Technical Field
[0001] The utility model relates to the technical field of fish collecting hoppers, in particular to a fish collecting hopper that prevents tipping and jamming and scraping. Background Art
[0002] Collecting, transporting and releasing fish over a dam is one of the ecological compensation methods for hydropower stations or reservoir dams. The fixed fish collecting station at the tail water outlet is the safest, most reliable and effective fish collecting facility so far. At present, the fish collecting hopper in its fish collecting pond has the following problems: 1) It is relatively light in weight (especially the inlet and outlet ends are even lighter than the fish releasing end), 2) The overall shape is funnel-shaped and the lower end and the center of gravity incline towards the fish releasing end. Due to the surging waves generated by the disordered flow field in the fish collecting pond, the pushing from the water inlet side and the driving of the water outlet, it often swings and shakes greatly when stopped, and it is difficult to maintain its stable posture in the water. Especially when lifting and lowering, there are even potential safety hazards of tipping over or getting stuck and scratched on the inner wall of the fish collecting pond. Summary of the Invention
[0003] The technical problem to be solved by the utility model is that the fish collecting hopper is prone to tipping over due to water flow impact and lifting force during the lifting process, and is easily damaged by getting stuck and scratched on the side wall of the fish collecting pond.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a fish collecting hopper that prevents tipping and jamming and scraping, which includes an installation frame with a rectangular frame structure and a funnel-shaped fish collecting tank fixed inside the installation frame. Connecting frames are vertically and fixedly arranged around the installation frame, and guiding pulleys are horizontally rotatably arranged on the connecting frames and are in contact with the inner side wall of the fish collecting pond.
[0005] Preferably, iron sand is poured into the pipe cavity at the bottom of the installation frame, and a counterweight iron bar is fixedly connected to the pipe wall at the bottom of the installation frame.
[0006] Preferably, an extension section is arranged at the top of the connecting frame in the length direction of the installation frame, and the guiding pulley is rotatably installed on the extension section. Connecting frames are arranged at both ends of the installation frame in the length direction.
[0007] Preferably, a closed plate is vertically and fixedly arranged on the side wall in the length direction of the installation frame, and the closed plate blocks the gap on the side of the installation frame.
[0008] Preferably, baffles are horizontally and fixedly arranged on both sides at the top of the installation frame, and the baffles are distributed in the gaps between adjacent connecting frames.
[0009] Preferably, a triangular support frame is fixedly arranged inside the installation frame, and both sides of the support frame are respectively connected to the side wall of the installation frame and the bottom wall of the fish collecting tank.
[0010] The present utility model provides a fish collecting hopper that prevents rollover and jamming and scraping. By fixedly arranging connecting frames around the mounting frame, guiding pulleys are installed through the connecting frames, and the guiding pulleys are in contact with the inner wall of the fish collecting pond, which can make the movement of the fish collecting hopper smoother; while strengthening the attitude stability of the fish collecting hopper in the vertical direction, it avoids rollover or jamming with the fish collecting pond wall when lifting.
[0011] 2. Pour iron sand and install iron bars as counterweights at the bottom of the mounting frame of the fish collecting hopper, so that the center of gravity of the fish collecting hopper is located at the bottom, and the attitude of the fish collecting hopper in the water is stabilized.
[0012] 3. Install a closing plate on the side of the fish collecting hopper. The closing plate closes the side of the mounting frame, which not only improves the overall firmness of the mounting frame, but also reduces the water inflow on both sides of the fish collecting hopper and the jacking effect of the turbulent flow at the bottom of the fish collecting pond on the bottom of the fish collecting tank; the closing of the side of the mounting frame can prevent fish from entering the mounting frame and being trapped and killed without being collected.

[0019] As Figures 1-4 shown, the present utility model provides a fish collecting hopper that prevents rollover and jamming and scraping, including a mounting frame 1 with a rectangular frame structure and a funnel-shaped fish collecting tank 2 fixed inside the mounting frame 1. Connecting frames 3 are vertically and fixedly arranged around the mounting frame 1, and guiding pulleys 4 are horizontally and rotatably arranged on the connecting frames 3, and the guiding pulleys 4 are in contact with the inner side wall of the fish collecting pond.
[0020] The mounting frame 1 adopts a rectangular frame structure with two layers. The fish collecting trough 2 has a funnel-shaped structure and is fixedly installed inside the mounting frame 1. The top of the fish collecting trough 2 is a rectangular plane and is fixedly connected to the side wall at the top of the mounting frame 1. A groove is provided at the bottom of the fish collecting trough 2, and the groove is arranged obliquely. A fish release gate is provided at the bottom end of the groove for releasing the fish in the fish collecting trough 2. Filter holes are arranged on the fish collecting trough 2 for water passing. During use, the hook of the winch is connected to the connecting ear on the mounting frame 1, and the fish collecting bucket is lowered into the fish collecting pool. Fishing bait is placed in the fish collecting trough 2. After a certain period of time, the fish collecting bucket is lifted by the winch. By using the rolling of the guiding pulleys 4 around the mounting frame 1 and the inner wall of the fish collecting pool, the smooth lifting and lowering process of the fish collecting bucket is ensured.
[0021] As a preferred embodiment of the present utility model. Iron sand is poured into the lumen of the bottom of the mounting frame 1, and a counterweight iron bar is fixedly connected to the bottom wall of the mounting frame 1. The iron sand and the counterweight iron bar are arranged at the bottom of the mounting frame 1 to ensure that the center of gravity of the fish collecting bucket is at the bottom, so that the fish collecting bucket can remain stable during the lifting process and is not prone to tipping over.
[0022] As Figures 1-4 shown. An extension section is provided at the top of the connecting frame 3 in the length direction of the mounting frame 1, and the guiding pulley 4 is rotatably installed on the extension section. The connecting frames 3 are arranged at both ends in the length direction of the mounting frame 1. Three lengthened connecting frames 3 are arranged on one side in the length direction of the mounting frame 1, and guiding pulleys 4 are also installed on the tops of the lengthened connecting frames 3 to extend the guiding length of the connecting frames 3, so that it can contact the inner side wall of the fish collecting pool through the guiding pulley 4 at the top after being lowered. A cross bar 5 is also connected between the tops of two opposite connecting frames 3, and diagonal bars are also arranged on the cross bar 5. The diagonal bars are fixedly connected to the connecting frames 3 to ensure the structural strength of the connecting frames 3.
[0023] As Figure 1 shown. A closed plate 7 is vertically and fixedly arranged on the side wall in the length direction of the mounting frame 1, and the closed plate 7 blocks the gap on the side of the mounting frame 1. The arrangement of the closed plate 7 can increase the connection strength between the top member and the bottom member of the mounting frame 1, and can also prevent fish from entering the inside of the mounting frame 1. Although the mounting frame 1 adopts a frame structure, in order to ensure its structural strength, multiple horizontal bars are provided at the bottom of the mounting frame 1. After the fish collecting bucket is lifted, it will be difficult to take out the fish stuck in the fish collecting bucket.
[0024] As Figure 1 and Figure 4 shown. Baffles 6 are horizontally and fixedly arranged on both sides at the top of the mounting frame 1, and the baffles 6 are distributed in the gaps between adjacent connecting frames 3. After the fish collecting bucket is lifted, by setting the baffles 6, the width of the fish collecting bucket is increased to prevent the fish in the fish collecting trough 2 from jumping out of the fish collecting bucket and falling to the ground, causing damage to the fish.
[0025] As Figure 3As shown in the figure, in order to improve the strength of the fish collecting tank 2. A support frame 8 with a triangular structure is fixedly arranged in the mounting frame 1, and both sides of the support frame 8 are respectively connected to the side wall of the mounting frame 1 and the bottom wall of the fish collecting tank 2.
