Description

Flat-bed composite rowing boat with balancing device
technical field
The present invention relates to a kind of rowing boat, especially a kind of
flat-plate composite material
rowing boat with balance plate.
Background technique
[0002] The rowing boat manufactured by the existing composite materials,
including the kayak, is a
composite material using glass fiber and carbon fiber as reinforcing material
and plastic as base
material. The fiber cloth is completed through the process of mold layup,
curing, cutting, repairing,
polishing and other processes. The production speed is slow, the labor is time-
consuming, and the cost
is high.
SUMMARY OF THE INVENTION
In order to solve the above-mentioned problems in the prior art, the present
invention provides a kind
of using flat plastic foam, cutting both sides of the plastic foam board by
simple tools, the two sides are
cut into polygonal diamond-shaped surfaces, and the middle of the two ends of
the hull is wide. The
core material is then sewn into a sleeve with glass fiber cloth, smeared with
resin to cover the core
material, wrapped with plastic film and cured, and then sewn with elastic
fiber cloth. Outside the cured
hull, the cockpit on the hull is made of waterproof fiber cloth sewn into a
cockpit cover, and a balance
plate is arranged behind the cockpit. The end face is immersed in water to
generate a reverse force to
restore the balance of the hull. Due to the balancing device, the hull can be
made narrower, thereby
increasing the speed.
The technical scheme that the present invention solves its technical problem
adopts is: a kind of flat-
plate composite material rowing boat with balancing device, comprises hull
(9), cockpit, balance plate
(4), it is characterized in that hull ( 9) The bow (10) to the stern (11) are
composite materials with flat-
type plastic foam (1) as the core material. The plastic foam (1) core material
is cut on both sides to form
the bow (10) tip, and the middle of the boat is wide, The core material at the
tip of the stern (11), the
core material is wrapped with a fiber cloth (2) coated with resin, and then a
plastic film is wrapped
around the fiber cloth, and then cured, and then an elastic fiber cloth cover
(3) is put on the outside
after curing; A cabin cover (12) sewn with waterproof fiber cloth is arranged
on the upper cabin of the
boat body (9), and the cabin cover (12) is sewn or bonded on the elastic fiber
cloth cover (3); the boat
body (9) is provided with a cabin cover (12). There is a balancing device,
which is arranged on both sides
of the hull (9) and is higher than the water surface. When the hull (9) is
inclined, one end of the
balancing device is immersed in the water to generate reverse buoyancy and
restore the balance.
The two sides of the flat-type plastic foam (1) core material of the above-
mentioned boat hull (9), the
two sides are cut into polygonal diamond-shaped surfaces (8), close to the bow
(10) and the stern (11),
gradually Cut with flat sides.
The above-mentioned cockpit cover (12) also includes a wire ring sewn into the
cover, and several
movable support rods are provided in the cockpit cover (12), and the support
rod supports the wire ring
to form a cockpit, and the upper part of the cockpit cover (12) is also

Above-mentioned balancing device comprises rotating type balancing plate (4),
and balancing plate (4)
center position is provided with rotating hole (6), rotating hole (6) to one
side, is provided with sliding
groove (7), balancing plate (4) Bolts are used to connect to the bottom of the
hull (9) through the
rotating hole (6), and plastic foam blocks (5) wrapped in fiber cloth are
arranged on both end faces of
the balance plate (4). The two sides are also respectively provided with
fixing straps (15) to the hull (9)

Above-mentioned rowing boat, comprises canoeing.
Above-mentioned rowing boat, also comprises boat bow and boat stern widening,
and the widened
boat stern can place the propeller of external hanging, can row, also can
machine propel.
The beneficial effect of the present invention is, the present invention has
the flat plate type composite
material rowing boat of balance board, comprises kayak, adopts plate type
plastic foam, cuts both sides
of plate by simple tool, makes solid core material boat body. Electric heating
wire or sheet is used for
cutting in this process, the equipment is simple, the processing speed is
fast, the cost is low, the weight
is light, it is not submerged, and the safety is high. The foam core material
is made of glass fiber cloth
sewn into a set. The process is low in labor time, low cost and neat in
appearance. The inner and outer
parts of the cloth cover are coated with resin and then wrapped around the
core material, and then
wrapped with a plastic film on the outer periphery to cure and form. This
process does not require a
mold, which saves the cost of mold manufacturing and the man-hours spent on
laying layers in the
mold. After that, a sleeve made of elastic fiber cloth is used, and the sleeve
is installed outside the cured
boat. This process does not require gel coat, no painting, no grinding,
repairing, and re-grinding, and no
grinding dust and water pollution during grinding are generated. Synthetic
fiber cloth is easy to dye and
has bright colors. It can also print pattern trademarks, and computer
embroidery trademarks and fonts.
The cockpit on the hull is made of waterproof fiber cloth sewn into the
cockpit cover, which is low cost,
light weight, small in size, easy to transport and store; a balance board is
set behind the cockpit, and the
balance board is higher than the set distance from the water surface. This
setting does not affect the
normal operation. The rowing speed, because the setting is in the air, when
the boat body is inclined to
the set angle, the end face of the balance plate is immersed in the water to
generate a reverse force, so
that the boat body is restored to balance. Because of the balance device, the
boat body can be made
narrower. thereby increasing the speed.
