Abstract
Description
Technical Field
[0001] This invention relates to the field of fish and shrimp farming technology, specifically to a pond bottom water quality monitoring robot for fish and shrimp farming. Background Technology
[0002] Disease severely restricts the development of the shrimp industry. Diseased shrimp carcasses are eaten by live shrimp, triggering outbreaks throughout the pond and wiping out all the shrimp. Often, by the time disease is detected, it's too late to reverse the damage. Uneaten feed and feces pollute the water, breeding bacteria and causing disease. Farms discharge wastewater 10 times daily, but there are often blind spots in the drainage. Uneaten feed and feces in these blind spots cause disease. Manual feeding relies entirely on experience; overfeeding not only increases farming costs but also pollutes the water and leads to disease.
[0003] Existing technologies for cleaning and water quality testing in aquaculture ponds cannot meet the needs of actual aquaculture. Dead corners in cleaning will affect water quality, and the sedimentation of uneaten feed and feces will affect the accuracy of water quality testing. At the same time, the aquaculture ponds are deep and turbid, making it impossible to clearly detect or observe the specific conditions of the water quality at the bottom of the pond, and thus impossible to judge the effectiveness of cleaning and sewage discharge.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1 to 6 The present invention provides a technical solution: A pond bottom water quality monitoring robot for fish and shrimp farming includes a submersible mobile base 1, with multiple sets of movable rollers 14 at the lower end of the submersible mobile base 1.
[0020] By setting rollers 14, the underwater mobile base 1 can be moved easily, enabling the monitoring robot to perform underwater mobile detection.
[0021] The inner side of the submersible mobile base 1 is equipped with an adjustable sampling base frame 3. The main control device 2 has a built-in drive component for adjusting the lifting of the sampling base frame 3 and a detection device for testing water quality. The drive component includes a lead screw 17. The lower end of the main control device 2 is equipped with an electrically driven lead screw 17. The upper middle of the sampling base frame 3 is vertically equipped with a helical tube 4. The upper end of the helical tube 4 is equipped with a downward-extending screw hole 30. The lead screw 17 is threadedly inserted into the screw hole 30. The inner wall of the submersible mobile base 1 is equipped with a lifting groove 12. The outer wall of the sampling base frame 3 is equipped with a side block 31 that slides up and down along the lifting groove 12.
[0022] The height of the sampling base frame 3 is adjusted by the screw rod 17 and the solenoid 4 rotating together. The lifting position is limited by the side block 31 and the lifting groove 12 to ensure the smoothness of the lifting.
[0023] The upper end of the submersible mobile base 1 is fixedly equipped with a main control device 2 located directly above the sampling base frame 3. The sampling base frame 3 is equipped with multiple sets of stirring blades 16 driven by motor 25. Multiple sets of stirring blades 16 are arranged in the inner cavity of the sampling base frame 3. There is a gap between adjacent stirring blades 16, and multiple sets of stirring blades 16 are linked together by a transmission belt.
[0024] By setting multiple sets of stirring blades 16, the rotation of the stirring blades 16 is used to stir the inner cavity of the sampling bottom frame 3, so that the residual feed and feces settled at the bottom of the pool are stirred up and mixed in the water flow, which facilitates the accurate sampling of water quality in the future and avoids the reduction of water quality detection accuracy due to sedimentation.
[0025] Sampling tubes 10 are fixedly installed on both sides of the sampling base frame 3. Side tubes 22 that are sleeved with the sampling tubes 10 are installed on both sides of the main control device 2. The lower end of the main control device 2 and the side tubes 22 are connected through a horizontally extending sampling channel 18. An I-shaped plug 24 is installed at the upper end of the sampling tube 10. The height of the plug 24 is greater than the inner diameter of the port of the sampling channel 18. The plug 24 slides against the lower inner wall of the side tube 22.
[0026] By setting the plug 24, the sampling and testing and drainage processes can be switched.
[0027] A piston rod 23 for lifting and lowering is provided in the side tube 22. A ball tube 11 is provided in the middle section of the sampling tube 10. A drainage box 5 is provided at the upper end of the main control device 2. The detection device of the main control device 2 and the drainage box 5 are both laterally connected to the side tube 22. A base is provided at the lower end of the visible top ball 6. The base extends to the top of the side tube 22. A telescopic drive rod 21 is provided at the lower end of the base. The lower end of the telescopic drive rod 21 is connected to the piston rod 23. The piston rod 23 is inserted vertically downward along the side tube 22. The piston at the end of the piston rod 23 extends into the sampling tube 10. The inner diameter of the middle section of the sampling tube 10 is smaller than the inner diameter of the ball tube 11. The piston at the end of the piston rod 23 slides along the inner wall of the sampling tube 10 and the side tube 22. The piston at the end of the piston rod 23 can extend into the inner cavity of the ball tube 11.
[0028] The piston rod 23 is raised and lowered by the telescopic drive rod 21, thereby raising the water level. When the piston at the lower end of the piston rod 23 moves into the inner cavity of the ball tube 11, the inner cavity of the sampling base frame 3, the side tube 22 and the sampling tube 10 are connected. When the piston rod 23 rises, it drives the water level in the side tube 22 to rise, thereby causing the water level to be discharged into the drainage tank 5 along the drainage channel 20, achieving the purpose of fixed-point sewage discharge.
[0029] The upper end of the drainage tank 5 is equipped with a visible top ball 6 located above the water surface. The sampling bottom frame 3 and the visible top ball 6 are connected by a return flow tube 8. The lower end of the visible top ball 6 is connected to the drainage tank 5 through a downpipe 7. The lower end of the drainage tank 5 is fixedly connected to the upper end of the main control device 2 by a connecting rod 33. The drainage tank 5 and the upper inner cavity of the side pipe 22 are connected by a drainage channel 20. The upper end port of the side pipe 22 and the drainage tank 5 are both located on the water surface. The inner cavity of the upper end port of the side pipe 22 is funnel-shaped. The drainage channel 20 extends downward at an angle. A drainage pipe 19 extending outward is provided on one side of the drainage tank 5. The drainage tank 5 can be filled with filter media for filtering water flow.
[0030] When the piston rod 23 descends, it squeezes the water flow in the sampling bottom frame 3. Under pressure, some of the water flow will flow back up along the return tube 8 to the visible top ball 6. By manually observing the state of the water flow in the visible top ball 6, the cleaning status of impurities at the bottom of the pool can be judged in a timely manner, avoiding repeated sampling and testing during the sewage discharge process, which greatly improves the efficiency of sewage discharge and cleaning.
[0031] Working principle: First, the rollers 14 facilitate the movement of the underwater mobile base 1, enabling the monitoring robot to perform underwater mobile detection. When it moves to a blind spot, the screw 17 and the solenoid 4 rotate in conjunction to drive the sampling base frame 3 to descend, covering the bottom of the pool. At this time, the rotation of the stirring fan blades 16 stirs the inner cavity of the sampling base frame 3, causing the residual feed and feces settled at the bottom of the pool to be stirred up and mixed in the water flow. This facilitates accurate water quality sampling and avoids a decrease in water quality detection accuracy due to sedimentation.
[0032] As the piston rod 23 descends, its piston is located in the ball tube 11. Driven by the descent, the plug 24 is located at the lower end of the port of the sampling channel 18. During the ascent of the piston rod 23, the stirred water is carried up and transported along the sampling channel 18 to the main control device 2 for water quality testing.
[0033] When the water quality test fails, the sampling bottom frame 3 is driven to rise slightly, causing the plug 24 to block the sampling channel 18 under the upward movement, thus switching between the sampling and sewage discharge processes. Then, the piston rod 23 is used to rise to raise the water level and discharge it into the drainage tank 5 along the drainage channel 20. When the piston rod 23 descends, it will squeeze the water flow in the sampling bottom frame 3. Under pressure, some of the water will flow back up along the return flow tube 8 to the visible top ball 6. By manually observing the state of the water flow in the visible top ball 6, the cleaning status of the impurities at the bottom of the pool can be judged in a timely manner, avoiding repeated sampling and testing during the sewage discharge process, and greatly improving the efficiency of sewage discharge and cleaning.
[0034] The lower end of the sampling base frame 3 is provided with a retractable frame-shaped grid 9, and the lower end of the sampling base frame 3 is provided with a storage groove 13. A first spring 15 is provided in the storage groove 13. The upper horizontal plate of the frame-shaped grid 9 is slidably inserted into the storage groove 13, and the first spring 15 is pressed between the upper horizontal plate of the frame-shaped grid 9 and the upper inner wall of the storage groove 13. Multiple sets of baffles are provided on both the inner and outer sides of the lower end port of the storage groove 13 to prevent the upper horizontal plate of the frame-shaped grid 9 from falling off.
[0035] By setting the first spring 15, the frame grid 9 is elastically installed, so that after the sampling bottom frame 3 rises, the elastic extension of the frame grid 9 supports the bottom of the pool and prevents fish and shrimp from entering the sampling bottom frame 3.
[0036] The upper end of the reflux tube 8 is connected to the visible top ball 6, and the lower end of the reflux tube 8 is slidably inserted into the sampling base frame 3. The end of the reflux tube 8 is provided with a detachable bottom ring 29, which is located in the inner cavity of the sampling base frame 3. The lower end of the reflux tube 8 is slidably sleeved with a collar 28, which is located in the inner cavity of the sampling base frame 3. A second spring 26 is pressed between the collar 28 and the bottom ring 29. The sampling base frame 3 is provided with a through hole for accommodating the reflux tube 8 to extend through. A rubber gasket 27 is fixedly provided at the lower end of the through hole, and the collar 28 abuts against the lower end of the rubber gasket 27.
[0037] By setting a second spring 26, the collar 28 is pressed against the rubber gasket 27, ensuring a simple seal at the through hole position and preventing rapid pressure loss, which would prevent the water flow from having sufficient pressure to flow back to the visible top ball 6.
[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
