Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a device for cleaning up uneaten feed during the temporary rearing and fattening of wild-caught swimming crabs. Background Technology

[0002] During the temporary rearing and fattening process of wild swimming crabs caught at sea, uneaten feed will rapidly decompose and cause a sharp increase in the concentration of ammonia nitrogen and nitrite in the water, disrupting water quality stability. Wild swimming crabs are extremely sensitive to water pollution, which can easily trigger stress reactions and even lead to diseases such as "milk disease," resulting in a decrease in the survival rate of temporary rearing. At the same time, traditional uneaten feed collection relies on manual collection at regular intervals, which is not only inefficient and labor-intensive, but also cannot cover the period when crabs concentrate uneaten feed after feeding, such as at night, creating obvious management blind spots. By the time manual collection is discovered, the uneaten feed has already partially decomposed and is difficult to completely remove. It may also disturb the crab population during the collection process, exacerbating their stress and mortality risk.

[0003] Currently, the industry mainly uses two types of uneaten feed treatment methods: one is traditional manual recycling, which relies on farmers to clean regularly with hand nets or suction pipes. This is not only inefficient (a single person can only handle 2-3 temporary holding ponds per day), but also makes it difficult to thoroughly clean uneaten feed from dead corners such as the bottom of the pond and the gaps in the crab apartments. The water disturbance during manual operation can also disturb the stress-sensitive wild swimming crabs, causing them to reduce their feeding frequency by 10%-15%. The other is general aquatic uneaten feed recycling equipment, which is mostly a pond bottom suction device designed for fish and shrimp. It uses a fixed-pore size filter screen (usually 5-10mm) and a constant-power suction pump, which cannot be adapted to the characteristics of swimming crabs. Summary of the Invention

[0004] The purpose of this invention is to provide a residual feed cleaning device for aquaculture, which can not only recover residual feed at the bottom of the aquaculture pond, but also clean residual feed in dead corners such as the crevices of crab apartments. While improving the cleaning effect, it can also adapt to the living characteristics of swimming crabs.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A device for cleaning up uneaten feed in aquaculture includes a mobile vehicle. A water storage tank with an open top is located at the middle of the upper end of the mobile vehicle. An openable tank cover is hinged between the left and right sides of the upper front end of the water storage tank. A water level gauge is installed on one side of the inner wall of the water storage tank. Limit frames are provided at the front and rear ends of the inner wall of the water storage tank, sloping downwards from front to back. A filter assembly is detachably connected to the upper end of the limit frame. Hollow telescopic rods are detachably connected between the left and right sides of the upper end of the mobile vehicle. A cleaning assembly is detachably connected to the front end of the telescopic rod. The mobile vehicle is equipped with an adjustable power first water pump and a second water pump at its front and rear ends. The inlet of the first water pump is connected to the rear end of the telescopic rod through a first water inlet pipe, and its outlet is connected to a first water outlet pipe extending above the filter assembly. The inlet of the second water pump is connected to a second water inlet pipe extending to the bottom of the inner wall of the water storage tank, and its outlet is connected to a return water pipe. A control cabinet is installed at the rear end of the mobile vehicle, and a power cord electrically connected to the control cabinet is provided on the outer wall of the control cabinet.

[0006] By adopting the above technical solution, when using the device, first move it to the location of the breeding pond that needs to be cleaned using a mobile vehicle, then plug the power cord into the socket to turn it on, then put the return water pipe into the breeding pond, operate the control cabinet to make the first water pump work and adjust the power of the first water pump according to the amount of uneaten feed and the amount of swimming crabs in the breeding pond, then the staff adjusts the length of the telescopic rod according to the height of the breeding pond, and then extends the cleaning component into the breeding pond. With the cooperation of the first water pump, the uneaten feed in the breeding pond is sucked out. At the same time, the sucked-out sewage will first be filtered through the filter component, and the filtered water will flow into the storage tank. When the water level height monitored by the water level gauge reaches the set threshold range, the second water pump works to pump the water in the storage tank back into the breeding pond, thus realizing water circulation and cleaning of uneaten feed at the same time.

[0007] A further embodiment of the present invention is that the mobile vehicle includes a base plate, rollers installed on the bottom of the base plate and arranged in an array, a handrail frame disposed between the left and right sides of the rear end of the base plate, and a placement rack disposed at the rear end of the handrail frame.

[0008] A further embodiment of the present invention is that the filter assembly includes a permeable frame with an open top and an inclined bottom, fixing strips respectively disposed at the front and rear ends of the inner wall of the permeable frame, and a filter screen detachably connected to the upper ends of the two fixing strips, wherein the mesh diameter of the filter screen is larger than the mesh diameter of the permeable frame.

[0009] By adopting the above technical solution, the two-stage filtration can not only improve the filtration effect of the water and increase the cleanliness of the water flowing back into the aquaculture pond, but also make it easier for staff to clean the impurities in the filter components after cleaning.

[0010] A further embodiment of the present invention is that the telescopic rod includes an outer tube, an inner tube that slides along the inner wall of the outer tube and extends out of its front end opening, a water guide pipe that communicates with the rear end of the inner tube and extends out of the rear end opening of the outer tube, and an installation sleeve that communicates with the front end of the inner tube.

[0011] By adopting the above technical solution, the length of the aquaculture pond can be flexibly adjusted according to its depth, which is convenient for staff to use and also provides a cleaning effect.

[0012] A further configuration of the present invention is as follows: the cleaning component includes a funnel-shaped housing that is smaller at the top and larger at the bottom, a first drive motor that is installed on the left and right sides of the lower inner wall of the housing, a connecting rod that is configured to cooperate between the power output shafts of the two first drive motors, a plurality of flexible scrapers that are equally spaced on the outer wall of the connecting rods and extend out of the lower opening of the housing, and waterproof covers that are respectively configured on the inner wall of the housing and used to cover the first drive motors.

[0013] By adopting the above technical solution, not only can the uneaten feed at the bottom of the aquaculture pond be cleaned, but the cover can also prevent swimming crabs from getting close to the flexible scraper. At the same time, the rotation of the flexible scraper will scrape up the uneaten feed at the bottom of the pond and achieve the cleaning effect.

[0014] A further configuration of the present invention is as follows: the cleaning component includes a tube with a rear end opening, a limiting ring disposed at the rear end of the outer wall of the tube, a slot opened rearward on one side of the front end of the outer wall of the tube, a second drive motor installed in conjunction with the rear end of the inner wall of the tube, a second waterproof cover sleeved on the outer wall of the second drive motor, and a cleaning brush rotatably connected between the front and rear ends of the inner wall of the tube and the power output shaft of the second drive motor, wherein the bristles of the cleaning brush extend out of the slot.

[0015] By adopting the above technical solution, the gaps and other dead corners of the crab apartment can be cleaned. Moreover, the cleaning not only adheres to the inner wall of the crab apartment, but also prevents the swimming crabs from coming into contact with the cleaning brush, thus avoiding stress to the swimming crabs.

[0016] A further feature of the present invention is that an activated carbon filter is detachably connected to and communicates with the rear end of the return water pipe.

[0017] A further feature of the present invention is that a water guide nozzle, which is duckbill-shaped and extends above the front end of the filter assembly, is provided at the upper end of the outer wall of the box cover at an angle from front to back, and the first water outlet pipe is connected to the water guide nozzle.

[0018] By adopting the above technical solution, it is not only convenient to fix the first outlet pipe, but also to expand the contact range between sewage and filter components through the duckbill-shaped setting, thereby improving the filtration effect on the water.

[0019] In summary, the present invention has the following beneficial effects: Firstly, this invention can not only recycle uneaten feed at the bottom of the breeding pond, but also clean uneaten feed in dead corners such as the gaps in the crab apartments, improving the cleaning effect while adapting to the living characteristics of swimming crabs. Secondly, when cleaning up leftover feed, the present invention can select the corresponding cleaning components according to the actual breeding situation, which can improve its applicability and the cleaning effect of leftover feed. Thirdly, the filter assembly of the present invention can not only improve the filtration effect on the water body and improve the cleanliness of the water flowing back into the aquaculture pond through two-stage filtration, but also make it easier for staff to clean the impurities in the filter assembly after cleaning.

The upper front end of the outer wall of the box cover 21 is inclined downward from front to back and has a water guide nozzle 24 that extends above the front end of the filter assembly 3 and is in the shape of a duckbill.

[0027] The upper end of the placement rack 14 is detachably connected to a hollow telescopic rod 34. The telescopic rod 34 includes an outer tube 35, an inner tube 36 that slides along the inner wall of the outer tube 35 and extends out of its front opening, a water guide pipe 37 that connects to the rear end of the inner tube 36 and extends out of the rear opening of the outer tube 35, and a mounting sleeve 38 that connects to the front end of the inner tube 36. The inner tube 36 is fixed to a fixing bolt on one side of the front end of the outer wall of the outer tube 35 by a threaded connection. The front end of the inner wall of the mounting sleeve 38 is provided with an internal thread. The front end of the telescopic rod 34 is detachably connected to a cleaning component 4 that communicates with it. The cleaning component 4 includes a component that is smaller at the top and larger at the bottom and has a leak-proof design. The enclosure consists of a bucket-shaped shell 401, two first drive motors 402 mounted opposite each other on the lower left and right sides of the inner wall of the shell 401, a connecting rod 403 configured between the power output shafts of the two first drive motors 402, several flexible scrapers 404 evenly distributed on the outer wall of the connecting rods 403 and extending out of the lower opening of the shell 401, and a first waterproof cover 405 respectively configured on the inner wall of the shell 401 to cover the first drive motors 402. The upper end of the outer wall of the shell 401 is provided with an external thread that is connected to the internal thread. The first waterproof cover 405 is made of a heat-conducting material to facilitate heat conduction.

[0028] The mobile vehicle 1 is equipped with an adjustable power first water pump 5 and a second water pump 53 at its front and rear ends. The inlet of the first water pump 5 is connected to the rear end of the water guide pipe 37 through a first inlet pipe 51, and its outlet is connected to the outer wall of the water guide nozzle 24 through a first outlet pipe 52. The inlet of the second water pump 53 is connected to a second inlet pipe 54 that extends to the bottom of the inner wall of the water storage tank 2, and its outlet is connected to a return pipe 55. The rear end of the return pipe 55 is detachably connected to an activated carbon filter 56. A control cabinet 15 is installed at the rear end of the mobile vehicle 1. A power cord 16 is provided on the outer wall of the control cabinet 15 and is electrically connected to it. The cleaning component 4, water level gauge 22, first water pump 5 and second water pump 53 are all electrically connected to the control cabinet 15 through connecting wires (figure not shown).

[0029] Usage: When using this device, first move it to the location of the breeding pond that needs to be cleaned using the mobile vehicle 1. Then, plug the power cord 16 into the socket to turn on the power. Next, put the return water pipe 55 into the breeding pond. Operate the control cabinet 15 to make the first water pump 5 work and adjust the power of the first water pump 5 according to the amount of uneaten feed in the breeding pond and the amount of swimming crabs. Then, the operator adjusts the length of the telescopic rod 34 according to the height of the breeding pond, so that the inner tube 36 slides along the outer tube 35 and extends a certain length beyond the front end of the outer tube 35 and is fixed. Then, extend the cleaning component 4 into the breeding pond and make the first drive motor 402 work through the control cabinet 15. The two first drive motors 402 drive the flexible scraper 404 on the connecting rod 403 to scrape up the uneaten feed accumulated at the bottom of the breeding pond and suck out the uneaten feed in the breeding pond with the cooperation of the first water pump 5.

[0030] Wastewater flows into the filter assembly 3 through the water guide pipe 37 and the first outlet pipe 52 for two-stage filtration. The water guide nozzle 24 increases the contact area between the wastewater and the filter screen 33, thereby improving the filtration effect. The filtered water flows into the water storage tank 2. When the water level monitored by the water level gauge 22 reaches the set threshold range, the second water pump 53 works to pump the water in the water storage tank 2 back into the breeding pond. The activated carbon filter 56 at the front end of the return water pipe 55 can improve the filtration effect of the return water. While realizing water circulation, it can also clean up the uneaten feed. After cleaning, the tank cover 21 can be opened to remove the filter assembly 3 for cleaning. If it is necessary to clean the telescopic rod 34 and the cleaning assembly 4, the first water pump 5 can be used to continuously pump clean water.

[0031] Example 2, refer to Figure 6 The difference from Embodiment 1 is that the cleaning component 4 includes a tube 411 with a rear end opening, a limiting ring 412 disposed on the rear end of the outer wall of the tube 411, a slot 413 opened on the front end side of the outer wall of the tube 411 and extending rearward, a second drive motor 414 installed in conjunction with the rear end of the inner wall of the tube 411, a second waterproof cover 415 sleeved on the outer wall of the second drive motor 414, and a cleaning brush 416 rotatably connected between the front and rear of the inner wall of the tube 411 and the power output shaft of the second drive motor 414. The bristles of the cleaning brush 416 extend out of the slot 413 and are made of silicone material with a Shore hardness of 30°. The second waterproof cover 415 is made of thermally conductive material to facilitate heat conduction. The rear end of the outer wall of the tube 411 is provided with external threads.

[0032] In terms of usage, when cleaning the crab apartment, the cleaning component 4 is inserted into the crab apartment through the telescopic rod 34, and then the second drive motor 414 is activated. The second drive motor 414 drives the cleaning brush 416 to rotate inside the tube 411, and the bristles of the cleaning brush 416 extend out of the slot 413. Therefore, by bringing the slot 413 close to the inner wall of the crab apartment, the residual bait can be cleaned off. At the same time, with the cooperation of the first water pump 5, the sewage containing residual bait can be pumped out.
