Description

Technical Field

[0001] The utility model relates to a raft structure and belongs to the technical field of aquaculture. Background Art

[0002] During fishery resource surveys, fish are caught using nets, placed in containers for easy measurement, and then returned to the water. To facilitate fishery resource surveys, these surveys are typically conducted on rafts, which are wider than ordinary boats, making it easier to place fishing nets and buckets, and allowing operators to move around and conduct operations. However, the biggest problem with current raft structures is that, for ease of operation, there are generally no fences on either side. Fishing nets and buckets are typically placed directly on the raft, forcing operators to be extremely careful to avoid tripping over the nets and falling, preventing them from fully focusing on their fishing efforts. Furthermore, the buckets themselves cannot be secured, and once the fish are placed in the buckets, the fish's struggles can easily cause the buckets to shift, or even fall into the water. Utility Model Content

[0003] The purpose of the utility model is to provide a raft structure, which is provided with a fishing net placement frame for loading the fishing net, so that people can devote themselves to fishing operations, and can also fix the fishing bucket to prevent the fishing bucket from being displaced and falling into the water.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0022] An embodiment of the utility model: a raft structure, including a raft body 1, a plurality of longitudinal fixing plates 2 are fixedly arranged at intervals on the surface of the raft body 1 along its width direction, the longitudinal fixing plates 2 are perpendicular to the raft body 1, and fixed limiting tubes 3 are vertically arranged in some of the longitudinal fixing plates 2 and the raft body 1 directly below them, and also includes a square-structured fishing net placement frame 4 and a circular fishing bucket placement frame 5, the fishing net placement frame 4 and the fishing bucket placement frame 5 can be formed by welding steel bars to each other, and the bottom of the fishing net placement frame 4 and the fishing bucket placement frame 5 are provided with a plurality of downward-extending fixed plugs 6, which can be inserted into the fixed limiting tubes 3.

[0023] When a fishery resource survey is needed, the fishing net frame 4 and the fishing bucket frame 5 can be lifted onto the raft body 1. The fixing plugs 6 at the bottom of the frames 4 and 5 are inserted into the fixed stop tubes 3. This secures the frames 4 and 5 via the fixed stop tubes 3, preventing them from shifting on the raft body 1. The fishing net is then placed into the fishing net frame 4, and the fishing bucket is placed into the fishing bucket frame 5. This prevents people from stepping on the fishing net while walking back and forth on the raft body 1, freeing them from having to worry about tripping over the net and allowing them to fully focus on their work. Placing the fishing bucket in the fishing bucket frame 5 prevents it from shifting or even falling into the water. When fishing is needed, the fishing net is removed from the fishing net frame 4, and the caught fish are promptly placed into the fishing bucket. After the survey is complete, the fish are promptly returned to the water. When there is no need to conduct a fishery resource fishing survey, the fishing net placement frame 4 and the fishing bucket placement frame 5 can be placed on land, so that the space of the entire raft body 1 is larger and it is more convenient to move back and forth.

[0024] In order to avoid the fishing net being easily caught in the fishing net placement frame 4 during the process of taking out and putting in, the fishing net placement frame 4 can be covered with woven bags inside, outside and bottom to avoid the net being hooked during the net placement process.

[0025] The raft body 1 includes a plurality of closely spaced PVC pipes 7. Compared to bamboo rafts, the PVC pipes 7 are lightweight, have high buoyancy, are corrosion-resistant, and have a long service life. Furthermore, the overall structure of the PVC pipes 7 remains consistent, resulting in a more aesthetically pleasing raft body 1 that is easy to install, maintain, and repair. The use of the PVC pipes 7 to manufacture the raft body 1 is conventional in the art, as described in CN103832558A and CN203921148U, and will not be elaborated on here.

[0026] Multiple longitudinal fixing plates 2 are fixedly mounted on the surfaces of the multiple PVC pipes 7. The fixed stop tubes 3 pass through the longitudinal fixing plates 2 and extend into the PVC pipes 7, contacting the inner bottom of the PVC pipes 7. The longitudinal fixing plates 2 are provided to securely connect the multiple PVC pipes 7 together, effectively forming a single unit. A penetration hole is provided on the longitudinal fixing plates 2, and a hole is drilled in the top of the PVC pipe 7 directly below the penetration hole. The diameters of the penetration hole and the drilled hole are exactly equal to the outer diameter of the fixed stop tube 3. The fixed stop tube 3 is then vertically inserted into the PVC pipe 7, contacting the inner bottom of the PVC pipe 7. This structure effectively secures the fixed stop tube 3, preventing it from shifting or shaking, thereby preventing the net placement frame 4 and the bucket placement frame 5 from shaking. The fixed stop tube 3 extends downward into the interior of the PVC pipe 7, but does not penetrate the bottom of the PVC pipe 7. This is to prevent water from entering the interior of the PVC pipe 7 through the bottom opening of the PVC pipe 7, which would increase the weight of the entire raft body 1.

[0027] At the same time, in order to avoid increasing the weight of the raft body 1, each PVC pipe 7 of the utility model is a separate PVC pipe from beginning to end, and both ends of each PVC pipe 7 are bent upward, which not only facilitates driving in the water, but also prevents water from entering the PVC pipe 7 from the end of the PVC pipe 7.

[0028] The outer side walls of the fixed limiting tube 3 are respectively bonded and fixed to the contact parts of the longitudinal fixing plate 2 and the PVC pipe 7, and the bottom of the fixed limiting tube 3 is in contact with the inner bottom of the PVC pipe 7 and bonded and fixed together. By applying glue on the outer wall and bottom of the fixed limiting tube 3, the fixed limiting tube 3 is bonded and fixed to the longitudinal fixing plate 2 and the PVC pipe 7, thereby achieving the fixation of the fixed limiting tube 3 and preventing the fixed limiting tube 3 from deflecting or shaking.

[0029] The surface of the fixed limiting tube 3 is flush with the surface of the longitudinal fixing plate 2. When the fishing net placement frame 4 and the fishing bucket placement frame 5 are not placed on the raft body 1, people can avoid touching the fixed limiting tube 3 exposed to the outside of the longitudinal fixing plate 2 and falling when walking back and forth on the raft body 1.

[0030] The bottom of the longitudinal fixing plate 2 is provided with a plurality of semicircular notches 8 adjacent to each other, and a plurality of PVC pipes 7 are inserted into the plurality of semicircular notches 8. The longitudinal fixing plate 2 and the PVC pipe 7 are bonded and fixed to each other by glue. The provision of a plurality of semicircular notches 8 can increase the contact area between the longitudinal fixing plate 2 and the PVC pipe 7, thereby making the two better connected and the connection more firm.

[0031] The raft body 1 further includes a T-shaped cover 9 that can be snapped onto the fixed position limiting tube 3. A rotatable pull ring 10 is provided on the surface of the cover 9. When the fishing net placement frame 4 and the fishing bucket placement frame 5 are not required on the raft body 1, the cover 9 is placed on the fixed position limiting tube 3 to prevent water from entering the PVC pipe 7 from the top opening of the fixed position limiting tube 3, thereby increasing the weight of the entire raft body 1. Normally, the pull ring 10 is rotated downward to contact the surface of the fixed position limiting tube 3. When the cover 9 needs to be removed, the pull ring 10 is pulled upward to facilitate the removal of the cover 9.

[0032] The fishing net placement frame 4 is provided with two fixed plugs 6 on the front, rear, left and right sides; the fishing bucket placement frame 5 is provided with one fixed plug 6 on the front, rear, left and right sides; the length of the fixed plug 6 is greater than 1 / 2 of the depth of the fixed limiting tube 3, ensuring that the fishing net placement frame 4 and the fishing bucket placement frame 5 will not shake after being placed on the raft body 1, and the installation is relatively firm.

[0033] The size of the fixed plug 6 should be 1-2 mm smaller than the diameter of the fixed limiting tube 3, which facilitates the insertion of the fixed limiting tube 3 and prevents the fishing net placement frame 4 and the fishing bucket placement frame 5 from shaking after placement.

[0034] In order to ensure the stability of the raft body 1, the fishing net placing frame 4 and the fishing bucket placing frame 5 should be installed in the middle position in the width direction of the raft body 1, and the width of the fishing net placing frame 4 and the fishing bucket placing frame 5 should not be greater than 1 / 2 of the raft body 1, ensuring that there is enough space on both sides of the fishing net placing frame 4 and the fishing bucket placing frame 5 for people to move back and forth.
