Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a sewage outlet for a fish pond. Background Technology
[0002] A fishpond drain outlet is a specially designed drainage outlet, usually installed at the bottom of the fishpond, used to clean up sewage and waste at the bottom of the pond. Its main function is to maintain stable water quality, thereby ensuring the healthy growth of fish.
[0003] First, if the drain outlet cannot be automatically cleared and there is no anti-clogging design, the drain outlet is easily blocked by fish excrement, feed residue and other impurities, resulting in poor drainage. Furthermore, the blockage problem will force users to clean the drain outlet frequently, increasing the frequency and cost of manual maintenance.
[0004] Secondly, the installation process of devices without a quick-installation design for the sewage outlet is cumbersome, requiring more time and tools, especially for large aquaculture ponds. Furthermore, the lack of a stable installation design may lead to loosening or leakage of the sewage outlet, affecting the normal operation of the equipment and even causing fluctuations in water quality.
[0005] Finally, without protective measures, fish may accidentally enter the sewage outlet and get injured or be discharged from the pond, affecting the safety of the fish population. Furthermore, sewage discharge relies on manual operation, and the lack of automatic control means that manual operation is still necessary, increasing the workload of management, which can become a burden, especially in large-scale aquaculture.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1:
[0030] Please see Figures 1-5 A sewage outlet for a fish pond includes a water tank 1, a dredging mechanism, a fixing mechanism, and auxiliary components. The dredging mechanism includes a motor 2, a transmission belt 3, a straight pipe 4, a dredging shaft 5, and a placement frame 6. The motor 2 is fixedly mounted on the placement frame 6, and the placement frame 6 is fixedly mounted on the bottom of the straight pipe 4. The two ends of the transmission belt 3 are respectively mounted on the dredging shaft 5 and the motor 2. The straight pipe 4 is fixedly mounted on the bottom of the water tank 1 and detachably connected to the water tank 1. The fixing mechanism includes a fixing plate 7, a connecting rod 8, a mating rod 9, and a first bolt 10. The fixing plate 7 is fixedly mounted on the bottom of the water tank 1 and detachably connected to the water tank 1 via the first bolt 10. The connecting rod 8 is mounted on the fixing plate 7 and threadedly engaged with the first bolt 10. The mating rod 9 is mounted on the connecting rod 8 and rotatably connected to the connecting rod 8. The first bolt 10 is threadedly engaged with the water tank 1.
[0031] In this embodiment, the unblocking mechanism includes a motor 2, a transmission belt 3, a straight pipe 4, an unblocking shaft 5, and a placement frame 6. During use, the motor 2, which is mounted on the placement frame 6, rotates, causing the transmission block 20 on the motor 2 to rotate as well. The transmission belt 3, which is mounted in the placement groove 21 of the transmission block 20, starts to drive the conveying shaft to rotate. The rotation of the conveying shaft inside the straight pipe 4 causes the rotating frame 17 on the placement plate 15 to rotate at the bottom of the pool 1. The cooperation between the rotating frame 17 and the fixed rod 16 tears apart any large foreign objects mixed in with the water flow that is about to enter the straight pipe 4. At the same time, the rotation of the booster blade 18 facilitates the transport of water. After the booster blade 18 has finished transporting the water, it goes directly to the conveying blade 19. The conveying blade 19 then transmits the water flow to the extension pipe 11 and finally discharges it.
[0032] In this embodiment, the fixing mechanism includes a fixing plate 7, a connecting rod 8, a mating rod 9, and a first bolt 10. In use, the fixing plate 7 is installed on the straight pipe 4, and the support plate 25 on the straight pipe 4 is placed into the pressure groove 26 of the fixing plate 7. The upright 22 at the bottom of the pool 1 then enters the connecting hole 23 in the fixing plate 7. At this time, the connecting rod 8 can be placed on the fixing plate 7, and then the first bolt 10 is inserted into the bolt hole 28 of the connecting rod 8 and tightened. At this time, the connecting rod 8 is squeezed, and the mating rod 9 on the connecting rod 8 directly enters the insertion hole 24 of the upright 22 under the squeezing of the connecting rod 8, thereby fixing the fixing plate 7 to the bottom of the pool 1, so that the straight pipe 4 can be fixed to the bottom of the pool 1. Since the other end of the straight pipe 4 is on the placement frame 6, and the placement frame 6 is in contact with the ground, there is no need to worry about the fixing of the straight pipe 4.
[0033] In this embodiment, the auxiliary components include an extension pipe 11, an electric valve 12, a fish shield 13, and a second bolt 14. When in use, the electric valve 12 installed on the extension pipe 11 in the suspension plate 27 is activated, allowing water to flow out of the extension pipe 11. When the motor 2 is running, the fish shield 13 is firmly fixed to the bottom of the pool 1 by the action of the second bolt 14. The rain shield can prevent fish from being injured by the unblocking shaft 5 and discharge large foreign objects to prevent complete blockage of the straight pipe 4.
[0034] Example 2:
[0035] In summary, during use, the first step is to install the straight pipe 4 and the motor 2. At this point, the fixing plate 7 is installed on the straight pipe 4, and the support plate 25 on the straight pipe 4 is placed into the pressure groove 26 of the fixing plate 7. The upright 22 at the bottom of the water tank 1 then enters the connecting hole 23 in the fixing plate 7. The connecting rod 8 can then be placed on the fixing plate 7, and the first bolt 10 is inserted into the bolt hole 28 of the connecting rod 8 and tightened. The connecting rod 8 is then compressed, and the mating rod 9 on the connecting rod 8, under the compression of the connecting rod 8, directly enters the insertion hole 24 of the upright 22, thus fixing the fixing plate 7 to the bottom of the water tank 1. This allows the straight pipe 4 to be fixed to the bottom of the water tank 1. Since the other end of the straight pipe 4 is on the placement frame 6, which is in contact with the ground, there is no need to worry about fixing the straight pipe 4. When everything is installed and sewage needs to be discharged, the motor 2 installed on the placement frame 6 rotates, causing the transmission block 20 on the motor 2 to also start rotating. The transmission belt 3 installed in the placement slot 21 of the transmission block 20 starts to drive the conveyor shaft to rotate. The rotation of the conveyor shaft inside the straight pipe 4 causes the rotating frame 17 on the placement plate 15 to rotate at the bottom of the pool 1. The cooperation between the rotating frame 17 and the fixed rod 16 tears apart large foreign objects mixed in the water flow that is about to enter the straight pipe 4. At the same time, the rotation of the booster blade 18 is conducive to the transportation of water flow. After the booster blade 18 finishes transportation, it goes directly to the conveyor blade 19. Then the conveyor blade 19 transmits the water flow to the extension pipe 11 and finally discharges it. When the above mechanism is running, the electric valve 12 installed on the extension pipe 11 in the suspension plate 27 is activated, so that the water flow can flow out of the extension pipe 11. When the motor 2 is running, the fish cover 13 is tightly fixed to the bottom of the pool 1 by the action of the second bolt 14. The rain cover can prevent fish from being injured by the unblocking shaft 5 and discharge large foreign objects to the outside, preventing complete blockage of the straight pipe 4.
[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
