Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a water quality control device for breeding and preventing diseases in aquatic fish fry. Background Technology

[0002] With the continuous development of the economy, the market demand for highly nutritious fish food is constantly increasing, resulting in the scale of fish farming becoming larger and larger. For fish farming ponds, it is necessary to constantly monitor their water quality and nutrient content to ensure the healthy growth of the fish.

[0003] Patent publication number CN115024263B discloses a water quality control device for disease prevention in aquaculture, including a float plate. The float plate is evenly divided into three parts, from left to right: a first collection box, a storage box, and a second collection box. The bottom of the storage box has a circular opening, and a feed hopper is fixedly connected to the opening. A support block is fixedly connected to the bottom of the feed hopper. A motor is fixedly installed at the top of the float plate. This patent mixes fish feed with oral medication and distributes it intermittently via a winch, avoiding concentrated feeding that could cause the fish to fall into the pond and affect the medication's effectiveness. A drive wheel propels the device forward, allowing for flexible movement of the feeding location. A shovel collects excrement and uneaten feed from the pond bottom, removes dense aquatic plants to control their density, and shreds them before pumping them onto the float plate, thereby reducing eutrophication and facilitating water quality control.

[0004] However, the device still has shortcomings: the device indirectly spreads the feed through a winch to ensure the consumption rate of the medicine, but as the fish reproduce, the thickness of the excrement and uneaten feed at the bottom of the water increases. At this time, simply scooping up the excrement and uneaten feed is not enough to effectively reduce the bacterial content, which can easily lead to the proliferation of a large number of bacteria in the fish pond water, which can easily affect the normal growth and reproduction of the fish. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a water quality control device for disease prevention and aquatic fish breeding, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water quality control device for disease prevention and aquatic fish breeding, comprising a carrier, a mixing tank at the bottom edge of the inner wall of the carrier, two symmetrically fixedly installed feeding shells at the bottom of the carrier, the top of the feeding shells communicating with the mixing tank, an electric rotating rod rotatably installed at the top of the mixing tank, the outer wall of the electric rotating rod located inside the feeding shells, a non-self-locking reciprocating spiral groove opened on the bottom outer wall of the electric rotating rod, several agitator plates equidistantly and fixedly installed on the top outer wall of the electric rotating rod, a spiral blade fixedly installed on the outer wall of the electric rotating rod, disinfection mechanisms fixedly installed on both the left and right sides of the carrier, a crossbar fixedly installed inside the square groove of the disinfection mechanism, a baffle plate rotatably installed through the outer wall of the crossbar by a torsion spring, a U-shaped plate movably installed through the outer wall of the reciprocating spiral groove of the electric rotating rod, an anti-compaction device for scooping up excrement provided below the U-shaped plate, and an anti-tipping device to improve the overall stability of the equipment provided around the anti-compaction device.

[0007] According to the above technical solution, a water trough is provided at the bottom of the carrier, and two arc-shaped partitions are symmetrically arranged inside the carrier to divide the interior into areas. The mixing bucket is used for mixing and storing feed and medicine. Floating mechanisms are provided on both the front and back outer walls of the carrier to provide buoyancy to the carrier in water. Several support rods are symmetrically and fixedly installed at the bottom of the carrier, and H-shaped seats are provided at the bottom of the support rods. Moving mechanisms are symmetrically arranged on the outer wall of the H-shaped seats to drive the entire device to move in the water. A sludge pump is provided at the top of the H-shaped seats, and the sludge pump is used to remove dirt from the bottom of the pond through pipes that pass through both the carrier and the H-shaped seats.

[0008] According to the above technical solution, the stirring plate is used to improve the mixing effect of feed and medicine; the spiral plate facilitates the spillage of feed during spiral conveying; the disinfection mechanism has a square groove at the bottom and contains chlorine dioxide to regulate the pond bottom environment; the baffle plate achieves rotation and reset through torsion spring force; the baffle plate indirectly sprays chlorine dioxide; the bottom of the baffle plate is located on the top movement trajectory of the U-shaped plate near the disinfection mechanism; the U-shaped plate indirectly flips the baffle plate. The plate, located at the top of the end furthest from the disinfection mechanism, is slidably installed inside the carrier. When the moving mechanism rotates underwater, it moves the H-shaped seat, which in turn moves the sludge pump and support rod synchronously. The sludge pump then moves its connected pipes synchronously, and the support rod moves the carrier synchronously. The carrier, in turn, moves the mixing tank and the feeding shell synchronously. When it is necessary to clean the excrement at the bottom of the fishpond, the sludge pump is activated. The pump transports the pumped excrement through the pipes into the carrier, and the arc-shaped baffle shields the excrement, preventing the mixing tank from being contaminated. Simultaneously, the water pumped by the sewage pump falls and is discharged through the carrier tank, reducing the carrier's weight while removing the excrement. The electric rotary rod is activated, causing the stirring plate to revolve. This revolve stirs the bait and medicine inside the mixing tank, ensuring better and more even mixing. When feeding is needed, the mixed bait is conveyed into the feeding shell through the mixing tank. The electric rotary rod also drives the spiral blades to revolve, which receive the bait in a revolving posture and use centrifugal force to propel it. The feed is thrown through the feeding shell to different directions and water depths, and the moving carrier causes the feeding location to change continuously. When the electric rotating rod rotates, it drives the U-shaped plate to slide upward and reset along the inside of the carrier through a non-self-locking reciprocating spiral groove. When the U-shaped plate moves upward, it contacts and pushes the shielding plate to generate a rotational force. The shielding plate flips along the outer wall of the crossbar in an arc trajectory due to the pushing action of the U-shaped plate. When the shielding plate flips, it releases the shielding of the bottom of the disinfection mechanism. Afterward, the shielding plate is reset by the torsion spring, so that the chlorine dioxide inside the disinfection mechanism falls indirectly into the fish pond.

[0009] According to the above technical solution, the anti-sludge device includes a U-shaped block, the top of which is fixedly installed at the bottom of a U-shaped plate. An arc-shaped baffle is fixedly installed on the top of the U-shaped block. The arc-shaped baffle is telescopic and has a built-in spring. The arc-shaped baffle blocks and guides the sewage falling from the carrier tank through its arc surface. When the U-shaped plate moves upward and resets, it drives the U-shaped block to move synchronously. The U-shaped block drives the arc-shaped baffle to move synchronously. The top of the telescopic end of the arc-shaped baffle contacts the bottom of the carrier and contracts. Then, the telescopic end of the arc-shaped baffle resets due to the spring force. Thus, the arc-shaped baffle guides the sewage falling from the carrier tank through its arc surface.

[0010] According to the above technical solution, a circular roller is rotatably installed inside the bottom end of the U-shaped block, an L-shaped shovel plate is slidably installed inside the H-shaped seat through a spring, the L-shaped shovel plate is horizontally reset by the spring force, a trapezoidal frame is fixedly installed on the side of the L-shaped shovel plate near the arc-shaped baffle, a circular rod is fixedly installed inside the H-shaped seat, and an irregularly shaped plate is rotatably installed through the outer wall of the circular rod by a torsion spring, and several hook-shaped teeth are equidistantly and fixedly installed inside the bottom end of the irregularly shaped plate.

[0011] According to the above technical solution, the bottom end of the L-shaped shovel plate scoops up the fish excrement deposited at the bottom of the fishpond. The inclined surface of the trapezoidal frame is located on the trajectory of the circular roller. The circular rod is located above the bottom end of the L-shaped shovel plate. The irregularly shaped plate completes the reset movement after flipping through a torsion spring. The hook-shaped teeth and the slots at the bottom end of the L-shaped shovel plate are staggered. The hook-shaped teeth are used to assist the L-shaped shovel plate in loosening the accumulated excrement. When the U-shaped block drives the circular roller to move upward, the outer wall of the circular roller contacts and rubs against the inclined surface of the trapezoidal frame. With the help of the circular roller's contact with the trapezoidal frame, the trapezoidal frame... The trapezoidal frame generates a horizontal force, causing the L-shaped shovel to slide horizontally along the inside of the H-shaped seat. During this process, the L-shaped shovel scoops up the compacted excrement at the bottom of the fishpond. At the same time, as the L-shaped shovel moves horizontally, it abuts against the top of the irregular plate, which generates a rotational force. When the irregular plate flips along the outer wall of the round rod in an arc trajectory, it drives the hook-shaped teeth to move synchronously. Afterward, when the irregular plate is reset by the torsion spring, it drives the hook-shaped teeth to reset synchronously. This process is repeated, causing the hook-shaped teeth to swing from top to bottom and strike the top of the compacted excrement.

[0012] According to the above technical solution, the anti-rollover device includes a transmission rod, which is rotatably installed on the outer wall of the H-shaped seat at one end near the sewage pump, and a disc is fixedly installed at the other end of the transmission rod away from the sewage pump. Several cutting blades are equidistantly and fixedly installed on the side of the disc near the L-shaped shovel plate.

[0013] According to the above technical solution, the outer wall of the transmission rod is provided with a non-self-locking spiral groove. The outer wall of the spiral groove of the transmission rod is penetrated and movably installed inside the L-shaped shovel plate. The cutting blade is used to cut aquatic plants or crush larger pieces of dirt. When the L-shaped shovel plate moves horizontally along the outer wall of the non-self-locking spiral groove of the transmission rod, the transmission rod is caused to generate rotational force and start to rotate by the limiting of the spiral groove. When the transmission rod rotates, it drives the disc to revolve. When the disc revolves, it drives the cutting blade to revolve. When the cutting blade revolves, it cuts the aquatic plants on the moving path of the H-shaped seat.

[0014] According to the above technical solution, two arc-shaped plates are symmetrically and fixedly installed on the outer wall of the disc, and a Z-shaped frame is slidably installed on the outer wall of the H-shaped seat through a spring. The top end of the Z-shaped frame, near the disc, contacts the arc surface of the arc-shaped plate. Several angled plates are equidistantly and fixedly installed inside the bottom end of the Z-shaped frame. The angled plates are used to remove obstacles on the moving path of the moving mechanism. When the disc revolves, it drives the arc-shaped plates to revolve. The arc-shaped plates revolve and disengage from the Z-shaped frame. At this time, the Z-shaped frame moves horizontally along the outer wall of the H-shaped seat towards the disc under the pull of the spring force. When the arc-shaped plate contacts the Z-shaped frame again, it will resist and push the Z-shaped frame to reset. This process is repeated, and the Z-shaped frame drives the angled plates to move synchronously. During the reciprocating horizontal movement, the angled plates push away obstacles such as stones on the moving path of the moving mechanism.

[0015] This invention provides a water quality control device for disease prevention and aquatic fish breeding. It has the following beneficial effects: (1) This invention uses a combination of a feeding shell, an electric rotating rod, a stirring plate, a spiral blade, a disinfection mechanism, a crossbar, a shielding plate, and a U-shaped plate. The stirring plate achieves uniform mixing of feed and medicine, resulting in a more balanced disease prevention treatment for the fish. It also expands the feeding range while effectively preventing concentrated feeding that could cause fish to fight for food and get injured. This ensures that the fish eat in a dispersed manner during feeding, further avoiding waste caused by feed settling due to insufficient use. Through the intermittent spraying of chlorine dioxide and the constantly moving carrier, the spraying area of ​​chlorine dioxide can be changed at any time, avoiding the impact of excessively concentrated chlorine dioxide spraying on fish reproduction. At the same time, chlorine dioxide disinfects and kills bacteria that grow on the bottom of the fish pond due to excrement and uneaten feed, ensuring good water quality in the fish pond and further preventing diseases in the fish.

[0016] (2) The present invention, through the setting of the anti-compact device, through the cooperation of U-shaped plate, U-shaped block, arc baffle, round roller, L-shaped shovel, trapezoidal frame, round rod, irregular plate and hook teeth, and through the guidance of the arc surface of the arc baffle, allows dirty water to flow away from the direction of bait throwing, avoiding dirty water from rushing into the bait throwing area and being eaten by the fish, and further avoiding fish diseases; through the swinging hook teeth, while the L-shaped shovel is horizontally shoveling the excrement, the hook teeth knock on the top of the excrement, accelerating the loosening rate of the excrement on the original basis, thereby improving the shoveling effect of the L-shaped shovel on compacted excrement, avoiding a large amount of excrement in a large piece when the L-shaped shovel is shoveling, and preventing the sewage pump from having a poor extraction effect on the dirt.

[0017] (3) The present invention, through the setting of the anti-tipping device, uses an L-shaped shovel, transmission rod, disc, cutting blade, arc plate, Z-shaped frame and corner plate to cut through the revolution of the cutting blade, avoids the obstruction of the movement of the equipment by the bottom water plants. At the same time, the cut water plants are easier to be pumped away and transported by the sewage pump, thereby reducing the content of water plants at the bottom of the fish pond and preventing them from absorbing a large amount of nutrients in the water and thus affecting the reproduction of fish. The corner plate pushes away obstacles such as stones in time, which to a certain extent ensures the stability of the moving mechanism during the movement process, avoids the movement mechanism from being unbalanced on one side due to collision with obstacles during the movement process, prevents the overall equipment from tilting during the movement process, and reduces the possibility of equipment imbalance.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-9 One embodiment of the present invention is: a water quality control device for disease prevention and aquatic fish breeding, comprising a carrier 1, a mixing tank 3 disposed at the bottom edge of the inner wall of the carrier 1, two feeding shells 9 symmetrically and fixedly installed at the bottom of the carrier 1, the top of the feeding shells 9 communicating with the mixing tank 3, an electric rotating rod 10 rotatably installed at the top of the mixing tank 3, the outer wall of the electric rotating rod 10 located inside the feeding shells 9, a non-self-locking reciprocating spiral groove opened on the outer wall of the bottom end of the electric rotating rod 10, and a plurality of equidistant and fixedly installed on the outer wall of the top end of the electric rotating rod 10. A stirring plate 11 and an electric rotating rod 10 are fixedly installed with spiral blades 12 on their outer walls. Disinfection mechanisms 13 are fixedly installed on both the left and right sides of the carrier 1. A crossbar 14 is fixedly installed inside the square groove of the disinfection mechanism 13. A baffle plate 15 is rotatably installed on the outer wall of the crossbar 14 through a torsion spring. A U-shaped plate 16 is movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod 10. A scooping device 17 is provided below the U-shaped plate 16 to prevent the excrement from being compacted. An anti-tipping device 18 to improve the overall stability of the equipment is provided around the anti-tipping device 17.

[0022] The bottom of the carrier 1 has a water trough. Two arc-shaped partitions 2 are symmetrically arranged inside the carrier 1 to divide the interior of the carrier 1 into areas. The mixing tank 3 is used for mixing and storing feed and medicine. The outer walls on both the front and back sides of the carrier 1 are equipped with floating mechanisms 4, which provide a certain buoyancy for the carrier 1 in the water. Several support rods 5 are symmetrically and fixedly installed at the bottom of the carrier 1. H-shaped seats 6 are set at the bottom of the support rods 5. Moving mechanisms 7 are symmetrically arranged on the outer wall of the H-shaped seats 6. The moving mechanisms 7 drive the entire equipment to move in the water. A sludge pump 8 is set at the top of the H-shaped seats 6. The sludge pump 8 passes through the carrier 1 and the interior of the H-shaped seats 6 through pipes. The sludge pump 8 is used to remove dirt from the bottom of the pond.

[0023] The stirring plate 11 is used to improve the mixing effect of feed and medicine. The spiral plate 12 facilitates the spillage of feed during spiral conveying. The disinfection mechanism 13 has a square groove at the bottom and contains chlorine dioxide to regulate the environment at the bottom of the pond. The shielding plate 15 is rotated and reset by the spring force of the torsion spring. The shielding plate 15 indirectly sprays chlorine dioxide. The bottom of the shielding plate 15 is located on the top movement trajectory of the U-shaped plate 16 near the disinfection mechanism 13. The U-shaped plate 16 indirectly flips the shielding plate 15. The top of the U-shaped plate 16 away from the disinfection mechanism 13 is inserted through and slidably installed inside the carrier 1.

[0024] The stirring plate 11 ensures uniform mixing of feed and medicine, achieving a more balanced disease prevention treatment for the fish. It also expands the feeding area while effectively preventing concentrated feeding that could lead to injury due to fish fighting for food. This ensures the fish feed in a dispersed manner, further avoiding waste caused by feed settling due to insufficient use. The intermittently sprinkled chlorine dioxide, along with the constantly moving carrier 1, ensures that the chlorine dioxide is continuously distributed to the pond's spraying area, preventing overly concentrated chlorine dioxide application from affecting fish reproduction. Simultaneously, the chlorine dioxide disinfects and kills bacteria generated by excrement and uneaten feed at the bottom of the pond, maintaining good water quality and further preventing fish diseases.

[0025] In use, the moving mechanism 7 rotates underwater, causing the H-shaped seat 6 to move. The H-shaped seat 6 drives the sludge pump 8 and the support rod 5 to move synchronously. The sludge pump 8 drives the pipes it is connected to to move synchronously, and the support rod 5 drives the carrier 1 to move synchronously. The carrier 1 drives the mixing tank 3 and the feeding shell 9 to move synchronously. When it is necessary to clean the excrement at the bottom of the fishpond, the sludge pump 8 is started. The sludge pump 8 transports the pumped excrement to the inside of the carrier 1 through the pipes, and the arc baffle 2 shields the excrement to prevent the mixing tank 3 from being contaminated by the excrement. At the same time, the water pumped by the sludge pump 8 falls and is discharged through the water tank of the carrier 1, completing the removal of excrement while reducing the weight of the carrier 1. The electric rotating rod 10 is started. When the electric rotating rod 10 rotates, it drives the stirring plate 11 to revolve. When the stirring plate 11 revolves, it stirs the feed and medicine inside the mixing tank 3, so that the two can be mixed better and more evenly. When feeding is needed, the mixed bait is conveyed into the feeding shell 9 through the mixing tank 3. When the electric rotary rod 10 rotates, it drives the spiral blade 12 to revolve. The spiral blade 12 receives the bait in a revolving posture and throws the bait through the feeding shell 9 to different directions and water depths through the centrifugal force of rotation. The moving carrier 1 causes the feeding location to change continuously. When the electric rotary rod 10 rotates, it drives the U-shaped plate 16 to slide upward and reset along the inside of the carrier 1 through the non-self-locking reciprocating spiral groove. When the U-shaped plate 16 moves upward, it contacts and pushes the shielding plate 15 to generate a rotational force. The shielding plate 15 flips along the outer wall of the crossbar 14 in an arc trajectory due to the pushing action of the U-shaped plate 16. When the shielding plate 15 flips, it releases the shielding of the bottom of the disinfection mechanism 13. Then the shielding plate 15 is reset by the torsion spring. Thus, the chlorine dioxide inside the disinfection mechanism 13 falls into the fish pond indirectly.

[0026] According to the above embodiments, the stirring plate 11 achieves uniform mixing of feed and medicine, enabling more balanced disease prevention treatment for the fish. It also expands the feeding area while effectively preventing concentrated feeding that could lead to injury due to fish fighting over food. This ensures that the fish feed in a dispersed manner, further avoiding waste caused by feed settling due to insufficient use. The intermittently sprinkled chlorine dioxide and the constantly moving carrier 1 ensure that the chlorine dioxide is constantly distributed to the pond's spraying area, preventing overly concentrated chlorine dioxide application from affecting fish reproduction. Simultaneously, the chlorine dioxide disinfects and kills bacteria generated by excrement and uneaten feed at the bottom of the pond, maintaining good water quality and further preventing fish diseases.

[0027] Please see Figures 1-9 Based on the above embodiments, another embodiment of the present invention further includes an anti-solidification device 17; The anti-sludge device 17 includes a U-shaped block 171. The top of the U-shaped block 171 is fixedly installed at the bottom of the U-shaped plate 16. An arc-shaped baffle 172 is fixedly installed on the top of the U-shaped block 171. The arc-shaped baffle 172 is telescopic and has a built-in spring. The arc-shaped baffle 172 blocks and guides the sewage and wastewater falling from the water tank of the carrier 1 through the arc surface.

[0028] A circular roller 173 is rotatably installed inside the bottom end of the U-shaped block 171. An L-shaped shovel 174 is slidably installed inside the H-shaped seat 6 via a spring. The L-shaped shovel 174 is horizontally reset by the spring force. A trapezoidal frame 175 is fixedly installed on the side of the L-shaped shovel 174 near the arc-shaped baffle 172. A round rod 176 is fixedly installed inside the H-shaped seat 6. A shaped plate 177 is rotatably installed through the outer wall of the round rod 176 via a torsion spring. Several hook-shaped teeth 178 are equidistantly and fixedly installed inside the bottom end of the shaped plate 177.

[0029] The bottom of the L-shaped shovel 174 shovels the fish excrement deposited at the bottom of the fishpond. The inclined surface of the trapezoidal frame 175 is located on the movement trajectory of the roller 173. The round rod 176 is located above the bottom of the L-shaped shovel 174. The irregular plate 177 completes the reset movement after flipping through the torsion spring. The hook teeth 178 and the groove at the bottom of the L-shaped shovel 174 are staggered. The hook teeth 178 are used to assist the L-shaped shovel 174 in loosening the accumulated excrement.

[0030] The curved surface of the arc-shaped baffle 172 guides the dirty water away from the direction of bait throwing, preventing it from flowing into the bait throwing area and being ingested by the fish, thus further preventing fish diseases. The swinging hook-shaped teeth 178 strike the top of the excrement while the L-shaped shovel 174 horizontally shovels it, accelerating the loosening rate of the excrement and improving the shoveling effect of the L-shaped shovel 174 on compacted excrement. This prevents the excrement from being in large pieces when the L-shaped shovel 174 shovels it, thus preventing the sewage pump 8 from being ineffective in removing the dirt.

[0031] In use, when the U-shaped plate 16 moves upward and returns to its original position, it drives the U-shaped block 171 to move synchronously. The U-shaped block 171 drives the arc-shaped baffle 172 to move synchronously. The top of the arc-shaped baffle 172 retracts when it touches the bottom of the carrier 1. Afterward, the top of the arc-shaped baffle 172 retracts due to the spring force. Thus, the arc-shaped baffle 172 guides the excrement and dirty water falling into the water tank of the carrier 1 through its own arc surface. When the U-shaped block 171 drives the roller 173 to move upward, the outer wall of the roller 173 contacts and rubs against the inclined surface of the trapezoidal frame 175. With the help of the roller 173 against the trapezoidal frame 175, the trapezoidal frame 175 generates a force for horizontal movement. The trapezoidal frame 175 causes the L-shaped shovel 174 to slide horizontally along the inside of the H-shaped seat 6. During this process, the L-shaped shovel 174 shovels the compacted excrement at the bottom of the fishpond. At the same time, when the L-shaped shovel 174 moves horizontally, it abuts against the top of the irregular plate 177. At this time, the irregular plate 177 generates a rotational force. When the irregular plate 177 flips along the outer wall of the round rod 176 in an arc-shaped trajectory, the irregular plate 177 will drive the hook tooth 178 to move synchronously. Afterwards, when the irregular plate 177 is reset by the torsion spring, it drives the hook tooth 178 to reset synchronously. This process is repeated to cause the hook tooth 178 to swing from top to bottom and strike the top of the compacted excrement.

[0032] According to the above embodiment, the arc surface of the arc-shaped baffle 172 guides the dirty water to flow away from the direction of bait throwing, preventing dirty water from flowing into the bait throwing area and being ingested by the fish, thus further preventing fish diseases; the swinging hook-shaped teeth 178, while the L-shaped shovel 174 is horizontally shoveling the excrement, the hook-shaped teeth 178 knock on the top of the excrement, accelerating the loosening rate of the excrement on the original basis, thereby improving the shoveling effect of the L-shaped shovel 174 on the compacted excrement, avoiding a large amount of excrement in a large piece when the L-shaped shovel 174 is shoveling, and preventing the sewage pump 8 from having a poor extraction effect on the dirt.

[0033] Please see Figures 1-9 Based on the above embodiments, another embodiment of the present invention further includes an anti-rollover device 18; The anti-rollover device 18 includes a transmission rod 181. The transmission rod 181 is rotatably installed on the outer wall of the H-shaped seat 6 at one end near the sewage pump 8. A disc 182 is fixedly installed at the other end of the transmission rod 181 away from the sewage pump 8. Several cutting blades 183 are equidistantly and fixedly installed on the side of the disc 182 near the L-shaped shovel plate 174.

[0034] The outer wall of the transmission rod 181 is provided with a non-self-locking spiral groove. The outer wall of the spiral groove of the transmission rod 181 is penetrated and movably installed inside the L-shaped shovel plate 174. The cutting blade 183 is used to cut aquatic plants or crush larger pieces of dirt.

[0035] Two arc-shaped plates 184 are symmetrically and fixedly installed on the outer wall of the disc 182. A Z-shaped frame 185 is slidably installed on the outer wall of the H-shaped seat 6 via a spring. The top of the Z-shaped frame 185 is in contact with the arc surface of the arc plate 184 at one end near the disc 182. Several angled plates 186 are equidistantly and fixedly installed inside the bottom of the Z-shaped frame 185. The angled plates 186 are used to remove obstacles on the moving path of the moving mechanism 7.

[0036] The cutting blade 183 rotates and cuts to prevent underwater weeds from obstructing the movement of the equipment. At the same time, the cut weeds are easier to be pumped and transported by the sewage pump 8, thereby reducing the content of underwater weeds at the bottom of the fishpond and preventing them from absorbing a large amount of nutrients from the water, which would affect the reproduction of the fish. The angled plate 186 pushes away obstacles such as stones in time, which to a certain extent ensures the stability of the moving mechanism 7 during the movement process. It also prevents the moving mechanism 7 from being unbalanced on one side due to collisions with obstacles during the movement, and prevents the overall equipment from tilting during the movement, reducing the possibility of equipment imbalance.

[0037] In use, when the L-shaped shovel 174 moves horizontally along the outer wall of the non-self-locking spiral groove of the transmission rod 181, the limiting force of the spiral groove causes the transmission rod 181 to generate rotational force and begin to rotate. The rotation of the transmission rod 181 drives the disc 182 to revolve, and the revolve of the disc 182 drives the cutting blade 183 to revolve. The revolve of the cutting blade 183 cuts the aquatic plants on the moving path of the H-shaped seat 6. The revolve of the disc 182 drives the arc-shaped plate 184 to revolve, and the arc-shaped plate 184... The Z-shaped frame 185 is released from its contact with the Z-shaped frame 185. At this time, under the pull of the spring force, the Z-shaped frame 185 moves horizontally along the outer wall of the H-shaped seat 6 towards the disk 182. When the arc plate 184 contacts the Z-shaped frame 185 again, it will resist and push the Z-shaped frame 185 to reset. This process is repeated, and the Z-shaped frame 185 drives the angle plate 186 to move synchronously. During the reciprocating horizontal movement, the angle plate 186 pushes away obstacles such as stones on the moving path of the moving mechanism 7.

[0038] According to the above embodiments, the cutting blade 183 rotates to cut, avoiding the obstruction of underwater weeds on the movement of the equipment. At the same time, the cut weeds are easier to be pumped and transported by the sewage pump 8, thereby reducing the content of weeds at the bottom of the fishpond and preventing them from absorbing a large amount of nutrients from the water, thus affecting the reproduction of fish. The corner plate 186 pushes away obstacles such as stones in time, ensuring the stability of the moving mechanism 7 during movement to a certain extent, avoiding the unilateral imbalance caused by collisions with obstacles during movement, preventing the overall equipment from tilting during movement, and reducing the possibility of equipment imbalance.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
