Lodging；Second, the edge of impeller lacks safeguard structure, is easy that web plate punching shear is caused to damage because colliding, influences net
Plate hydrodynamic performance.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind to help the vertical trawl board of vertical type, is conducive to trawl board and exists
It is adjusted to the posture for standing and effectively keeping standing in water, the edge of web plate impeller is avoided to deform cause damage because colliding.
The technical solution adopted by the present invention to solve the technical problems is to provide one kind and helps the vertical trawl board of vertical type, including
Top plate, warp plate, bottom plate and several cambered surface impeller frames are distinguished between the top plate and warp plate, between bottom plate and warp plate
It is symmetrically arranged with several cambered surface impeller frames, interval, which is provided with, on the cambered surface impeller frame several engraves hole, the top plate and warp plate
Between engraving for cambered surface impeller frame the first filling plate is inlayed inside hole, the cambered surface impeller frame between the bottom plate and warp plate
The second filling plate is inlayed in engraving for frame inside hole, the density of the first filling plate is low compared with the second filling plate, the cambered surface
The two sides of impeller frame is respectively fixed with cover plate, and the edge of the cambered surface impeller frame is equipped with protection rib.
It is described first filling plate, second filling plate and cover plate respectively with the radian of corresponding cambered surface impeller frame
Match, the size and thickness of the first filling plate and the second filling plate match with corresponding hole of engraving respectively.
The protection rib is integrally cylindrical and is provided with mounting groove along its length, and the protection rib passes through mounting groove
Encapsulation in cambered surface impeller frame edge and fixed by fastener.
The protection rib is made of ballistic resistant material.
First inlayed inside hole of engraving of cambered surface impeller frame between the top plate and warp plate fills panel density certainly
It is gradually increased under above, the cambered surface impeller frame between the bottom plate and warp plate engraves the second filling plate inlayed inside hole
Density is gradually increased from top to bottom.
The trawl board is integrally V-shaped.
The cover plate is fixed by fastener and cambered surface impeller frame.
Beneficial effect
First, in the present invention, pass through engraving for the cambered surface impeller frame of the cambered surface impeller frame and lower part on web plate top
The filling plate of different densities is inlayed in hole respectively, so that web plate top quality lower part light weight, the decline of web plate center of gravity, it can
Web plate is easily adjusted to the state of standing in water body, and makes trawl board that this effectively be kept to hang down always in operation process
Standing position state.
Second, in the present invention, protection rib is installed at the edge of cambered surface impeller frame two sides, protection rib is using anti-
It hits material to be made, the edge that can be avoided web plate impeller causes punching shear to cause damage because colliding, and web plate water is effectively ensured
Power performance.

Fig. 2 is the cross section structure schematic diagram of web plate top of the present invention impeller.
Fig. 3 is the cross section structure schematic diagram of web plate lower part of the present invention impeller.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
One kind as shown in Figures 2 and 3 helps the vertical trawl board of vertical type, including top plate 1 as shown in Figure 1, warp plate 2,
Bottom plate 3 and cambered surface impeller frame 4.
As shown in Figure 1, be welded with four pieces of cambered surface impeller frames 4 between top plate 1 and warp plate 2, bottom plate 3 and warp plate 2 it
Between be welded with four pieces of cambered surface impeller frames 4, the cambered surface impeller frame 4 of top and the bottom is symmetrically V-shaped respectively.Each cambered surface impeller frame
It is opened to matrix distribution on frame 4 and spaced engraves hole 5.
As shown in Fig. 2, the engraving for cambered surface impeller frame 4 between top plate 1 and warp plate 2 inlays the first filling plate inside hole 5
Material 6, the size and thickness of the first filling plate 6 match with the hole 5 of engraving filled respectively, radian and corresponding cambered surface impeller frame
4 match.First filling plate 6 uses foamed material, and density is minimum, advantageously reduces web plate top quality.
