A zooplankton delivery device and its technology for river management

Abstract

This invention belongs to the field of river management technology. It discloses a zooplankton release device and its process for river management. The device includes a counterweight box mounted on top of a support plate. A counterweight block is fixedly connected inside the counterweight box, and a cylinder is fixedly connected to the outside of the counterweight block. The output end of the cylinder passes through the counterweight box and extends to its outer side. A connecting plate is fixedly connected to the output end of the cylinder, and a release box is fixedly connected to the end of the connecting plate opposite to the cylinder. Through the structural design of the adjustment mechanism, bottom pipe, and guide square tube, this device enables the water flow to drive the adjustment mechanism, which in turn drives the bottom pipe and guide square tube to continuously oscillate back and forth. This allows the zooplankton to be evenly released into different areas of the river through the guide square tube, solving the problem of uneven distribution of zooplankton during release, which may result in localized over- or under-release and affect the river's ecological restoration effect.

Description

Technical Field

[0001] This invention relates to the field of river management technology, and more specifically, to a zooplankton release device and its process for river management. Background Technology

[0002] Zooplankton is a general term for heterotrophic invertebrates and chordate larvae that frequently float in water and cannot produce organic matter themselves. They are a group of animals that live a planktonic life in water. With the rapid development of industrialization and urbanization, river pollution and ecological damage have become increasingly serious problems. Zooplankton in rivers are an important part of the aquatic ecosystem and play a key role in water purification, ecological balance and the maintenance of aquatic biodiversity. In order to facilitate the release of zooplankton into rivers, release devices are needed.

[0003] The existing release devices are mostly release boxes. Artificially cultivated zooplankton—algae-eating insects—are poured into the release box along with the water source. Some trace elements are added to the release box to promote the growth of the algae-eating insects. Then the release box is transported to a designated river, and the algae-eating insects in the release box are poured into the river, thus completing the algae-eating insect release process.

[0004] However, the existing release devices are not precise enough, resulting in uneven distribution of algae-eating insects during the release process. This may lead to local over- or under-release, affecting the ecological restoration of the river. During the release process, trace elements tend to accumulate at the bottom of the release box, preventing them from being evenly distributed in the area where the algae-eating insects are located, thus affecting their reproduction. Summary of the Invention

[0011] Furthermore, a float plate, made of polyurethane foam, is slidably connected inside the delivery box. A pair of first limiting rods penetrate the interior of the float plate, with both ends of the first limiting rods fixed to the inner wall of the delivery box. A first sprocket is located at the top of the delivery box, with a second connecting rod rotatably connected inside the first sprocket and fixed to the top of the delivery box. A second sprocket is located outside the first sprocket, with a third connecting rod rotatably connected inside the second sprocket and fixed to the outside of the delivery box. A nylon rope is fixed to the top of the float plate, and the nylon rope is located away from... One end of the float passes through the release box and extends to the outside of the release box. The nylon rope passes through one end of the release box and is wrapped around the outside of the first sprocket and the second sprocket.

[0014] A process for releasing zooplankton into rivers for river management, comprising the following steps:

[0015] S1. First, pour the algae-eating insects along with the water source into the feeding box through the inlet, and add trace elements suitable for the growth of the algae-eating insects into the feeding box. The solenoid valve at the bottom of the feeding box is in the closed state.

[0016] S2. Then move the delivery box to the designated river, place the pallet on the riverbank, start the cylinder, and the cylinder will move the delivery box toward the center of the river.

[0017] S3. Place one end of the mixing mechanism in the river, start the mixing mechanism, the mixing mechanism draws water from the river, the water from the river enters the interior of the first connecting box, and finally, the water source is sprayed into the interior of the delivery box through the nozzle;

[0018] S4. The sprayed water creates a water vortex inside the dispensing tank, accelerating the mixing of trace elements inside the tank.

[0019] S5 also disperses the algae-eating insects, preventing them from accumulating in one place inside the distribution box and causing uneven distribution in subsequent distributions.

[0020] The technical effects and advantages of the present invention regarding a zooplankton release device and its process for river management are as follows:

[0021] (1) Through the structural design of the regulating mechanism, bottom pipe and guide square tube, the water flow drives the regulating mechanism to operate, and the regulating mechanism in turn drives the bottom pipe and guide square tube to swing back and forth continuously, so that the algae-eating insects are evenly released into different areas of the river through the guide square tube. This solves the problem that the algae-eating insects are unevenly distributed during the release process, and there may be local over-release or under-release, which affects the ecological restoration effect of the river.

[0022] (2) Through the structural design of the mixing mechanism and the nozzle, the mixing mechanism sprays water into the inside of the feeding box through the nozzle, thereby achieving the function of dispersing algae-eating insects and trace elements. This solves the problem that trace elements are easy to accumulate at the bottom of the feeding box, causing the trace elements to be unable to be evenly distributed in the area where the algae-eating insects are located during the feeding process, thus affecting the reproduction of the algae-eating insects.

[0023] (3) Through the structural design of the float plate, the first electrical contact plate, the second electrical contact plate and the moving mechanism, the float plate can drive the first electrical contact plate and the second electrical contact plate to fit together according to the actual water level. The external controller then receives the information from the first electrical contact plate and the second electrical contact plate and controls the start and stop of the nozzle through the moving mechanism. This plays a role in using the nozzle carefully to prevent adverse effects on algae-eating insects and improves the safety of the device during operation. Attached Figure Description

[0037] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1 - Figure 8As shown, a zooplankton release device for river management includes a counterweight box 2 mounted on top of a support plate 1. A counterweight block 3 is fixedly connected inside the counterweight box 2, and a cylinder 4 is fixedly connected to the outside of the counterweight block 3. The output end of the cylinder 4 passes through the counterweight box 2 and extends to the outside of the counterweight box 2. A connecting plate 5 is fixedly connected to the output end of the cylinder 4. A release box 6 is fixedly connected to the end of the connecting plate 5 opposite to the cylinder 4. An inlet 7 is fixedly connected to the outside of the release box 6, and the inlet 7 communicates with the inside of the release box 6. A solenoid valve is installed at the bottom of the release box 6 to control the flow of liquid inside the release box 6. A nozzle 8 is fixedly connected to the inner wall of the release box 6. The device also includes…

[0039] A mixing mechanism is provided at the top of the tray 1, which is used to provide water to the nozzle 8;

[0040] An adjustment mechanism is provided at the bottom of the dispensing box 6. The adjustment mechanism includes a first connecting box 9, a second connecting box 10, and a bottom tube 11. The first connecting box 9 and the second connecting box 10 are fixedly connected to each other. The bottom tube 11 is rotatably connected to the bottom of the dispensing box 6. A guide square tube 12 is fixedly connected to the bottom of the bottom tube 11. The guide square tube 12 communicates with the interior of the bottom tube 11. The adjustment mechanism is used to adjust the angle of the guide square tube 12.

[0041] First, the algae-eating insects, along with the water source, are poured into the feeding box 6 through the inlet 7. Trace elements suitable for the growth of the algae-eating insects are added to the inside of the feeding box 6. The solenoid valve at the bottom of the feeding box 6 is closed. Then, the feeding box 6 is moved to a designated river, the tray 1 is placed on the riverbank, and the cylinder 4 is activated. The cylinder 4 moves the feeding box 6 towards the center of the river. However, the existing feeding device design is not precise enough, resulting in uneven distribution of the algae-eating insects during the feeding process, potentially leading to localized over- or under-feeding, affecting the river's ecological restoration effect. During the feeding process, trace elements tend to accumulate at the bottom of the feeding box, preventing even distribution to the algae-eating insects and affecting their reproduction. To solve these problems, in this embodiment of the invention, one end of the mixing mechanism is placed in the river, and the mixing mechanism is activated. The mixing mechanism draws water from the river, which enters the first connecting box 9. Finally, the water source is sprayed into the feeding box 6 through the nozzle 8. The ejected water creates a vortex inside the distribution box 6, accelerating the mixing of trace elements and dispersing the algae-eating insects. This prevents them from accumulating in one place and causing uneven distribution during subsequent distributions. It's important to note that during the water flow inside the distribution box 6, the water source remains below the inlet 7, preventing the water and algae-eating insects from leaving the box. The first connecting box 9 activates the regulating mechanism during water flow, causing the bottom pipe 11 to rotate repeatedly, which in turn causes the guide square pipe 12 to swing back and forth. Opening the solenoid valve at the bottom of the distribution box 6 allows the water and algae-eating insects to enter the bottom pipe 11 and eventually flow into the designated river through the guide square pipe 12. The continuous swinging of the guide square pipe 12 adjusts the distribution area, preventing over- or under-distribution of water and algae-eating insects in a single area.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the mixing mechanism includes a water pump 13, which is fixedly connected to the top of the support plate 1. The output end of the water pump 13 is fixedly connected to a first water pipe 14, which is fixedly connected to the outside of a first connecting box 9. A second water pipe 15 is fixedly connected to the end of the first connecting box 9 away from the first water pipe 14. A connecting pipe 16 is provided at the end of the second water pipe 15 away from the first connecting box 9. A third water pipe 17 is provided at the end of the connecting pipe 16 away from the second water pipe 15. The end of the third water pipe 17 away from the connecting pipe 16 is fixedly connected to the outside of a nozzle 8. The nozzle 8 and the interior of the third water pipe 17 are interconnected.

[0043] Place the inlet of the water pump 13 in the river and start the water pump 13. The water pump 13 draws water from the river into the first water pipe 14. The water in the first water pipe 14 then enters the second water pipe 15 through the first connecting box 9. Finally, the water in the second water pipe 15 enters the nozzle 8 through the connecting pipe 16 and the third water pipe 17. The nozzle 8 sprays the water into the dispensing box 6, thereby achieving the function of dispersing algae-eating insects and trace elements.

[0044] like Figure 6 , Figure 7 and Figure 8 As shown, the adjusting mechanism also includes an impeller 18. The outer side of the impeller 18 is disposed inside the first connecting box 9. A support rod 19 is fixedly connected inside the impeller 18. One end of the support rod 19 is rotatably connected to the inner wall of the second connecting box 10. The end of the support rod 19 away from the second connecting box 10 passes through the second connecting box 10 and is fixedly connected to a side plate 20. The end of the side plate 20 away from the support rod 19 is rotatably connected to a slider 21. A straight groove 22 is slidably connected to the outer side of the slider 21. A rack 23 is fixedly connected to the top of the straight groove 22. A pair of second limiting rods 24 pass through the inside of the rack 23. Both ends of the second limiting rod 24 are fixedly connected to L-shaped plates 25. A pair of L-shaped plates 25 are respectively fixedly connected to both ends of the second connecting box 10. A fixing rod is fixedly connected to the opposite end of the pair of L-shaped plates 25. The end of the fixing rod away from the L-shaped plate 25 is fixedly connected to the outside of the delivery box 6. A first spur gear 26 is meshed on the outside of the side plate 20. A first connecting rod 27 is rotatably connected inside the first spur gear 26. The first connecting rod 27 is fixedly connected to the outside of the delivery box 6. A second spur gear 28 is meshed on the outside of the first spur gear 26. The second spur gear 28 is rotatably connected to the outside of the bottom tube 11.

[0045] When water from the first water pipe 14 enters the first connecting box 9, the water impacts one side of the impeller 18, forcing it to rotate. This rotation of the impeller 18 then drives the support rod 19 to rotate, which in turn causes the side plate 20 to rotate around the support rod 19. The rotation of the side plate 20 further drives the slider 21 to rotate along the inside of the straight groove 22. During this movement, the slider 21 causes the straight groove 22 to reciprocate laterally. It should be noted that the movement distance of the straight groove 22 will not exceed the second limit rod 24. When the straight groove 22 moves back and forth, it will drive the rack 23 fixed at its top to move back and forth. The movement of the rack 23 will drive the first spur gear 26 to rotate. The rotation of the first spur gear 26 will then drive the bottom tube 11 to rotate back and forth through the second spur gear 28. The bottom tube 11 will eventually drive the guide square tube 12 to move back and forth around the bottom tube 11 as the circumference point. At this time, when the algae-eating insects and water source inside the release box 6 enter the guide square tube 12 through the bottom tube 11, the guide square tube 12 will continuously swing back and forth to evenly distribute the algae-eating insects and water source in different areas of the river.

[0046] like Figure 9 and Figure 10 As shown, a float 29 is slidably connected inside the delivery box 6. The float 29 is made of polyurethane foam. A pair of first limiting rods pass through the inside of the float 29, and both ends of the pair of first limiting rods are fixedly connected to the inner wall of the delivery box 6. A first sprocket 30 is provided at the top of the delivery box 6. A second connecting rod 31 is rotatably connected inside the first sprocket 30 and is fixedly connected to the top of the delivery box 6. A second sprocket 32 ​​is provided outside the first sprocket 30. A third connecting rod 33 is rotatably connected inside the second sprocket 32 ​​and is fixedly connected to the outside of the delivery box 6. A nylon rope 34 is fixedly connected to the top of the float 29, and the nylon rope 34 is away from the float. One end of the float 29 passes through the delivery box 6 and extends to the outside of the delivery box 6. One end of the nylon rope 34 passes through the delivery box 6 and is wrapped around the outside of the first sprocket 30 and the second sprocket 32. The bottom end of the float 29 is fixedly connected to the first electrical receiving plate 35. The second electrical receiving plate 36 is arranged directly below the first electrical receiving plate 35 and is fixedly connected to the inner wall of the delivery box 6. The first electrical receiving plate 35 and the second electrical receiving plate 36 are both made of waterproof material. A moving mechanism is arranged on the outside of the connecting pipe 16. The first electrical receiving plate 35, the second electrical receiving plate 36 and the moving mechanism are all electrically connected to an external controller. The external controller is used to receive signals from the first electrical receiving plate 35 and the second electrical receiving plate 36 and control the operation of the moving mechanism.

[0047] When the water level inside the dispensing tank 6 is half or lower, if the nozzle 8 generates an air vortex in the water inside the dispensing tank 6, causing the water to flow rapidly, such a water flow environment may harm the algae-eating insects. To solve the above problem, in the initial state of use, the water inside the dispensing tank 6 supports the float 29 to float. When the solenoid valve at the bottom of the dispensing tank 6 is opened, the water level inside the dispensing tank 6 will drop. Since the float 29 is made of polyurethane foam and has its own weight, the float 29 will drop along with the water level and remain level with the water level. It should be noted that the water flowing out of the dispensing tank 6 should be fast. The water level drops to half its maximum when it enters the water source through the nozzle 8. At this point, the float 29 lowers the first contact plate 35, bringing it into contact with the second contact plate 36. The float 29 must descend to its maximum distance above the nozzle 8. At this point, the external controller receives information about the contact between the first and second contact plates 35 and 36 and activates the moving mechanism. This mechanism moves the connecting pipe 16 upwards, disconnecting it from the connection between the second and third water pipes 15 and 17. When the connecting pipe 16 is above the second water pipe 15, the moving mechanism stops. At this point, water from the second water pipe 15 can no longer flow through the third water pipe 17. 7 enters the interior of the nozzle 8, thus preventing the nozzle 8 from continuing to spray even when the water level is too low. The nozzle 8 is then stopped, preventing the water sprayed from the nozzle 8 from harming the algae-eating insects. Through this structural design, the start and stop of the nozzle 8 are controlled according to the actual water level, ensuring careful use of the nozzle 8 to prevent adverse effects on the algae-eating insects and improving the safety of the device operation. When it is necessary to add water and algae-eating insects to the inside of the feeding tank 6 again, first pull the end of the nylon rope 34 away from the float 29. The nylon rope 34, under force, will then move along the second sprocket 32 ​​and the first sprocket 3... 0, which drives the float 29 to move upward. During the upward movement of the float 29, the first electrical contact plate 35 is simultaneously disengaged from the second electrical contact plate 36. At this time, the external controller receives the signal that the first electrical contact plate 35 and the second electrical contact plate 36 have disengaged, and will control the connecting pipe 16 to move downward and reset, reconnecting the second water pipe 15 and the third water pipe 17. When the float 29 moves above the connection between the feed inlet 7 and the feeding box 6, algae-eating insects can be fed into the feeding box 6 and water can be added through the feed inlet 7. Then, the nylon rope 34 is released, and the water inside the feeding box 6 will support the float 29 to float again, thus facilitating the repetition of the above actions.

[0048] like Figure 9 and Figure 10As shown, the moving mechanism includes a sliding plate 37, which is fixed to the outside of the connecting pipe 16. Both ends of the sliding plate 37 are slidably connected to third limiting rods 38. The bottom ends of a pair of third limiting rods 38 are respectively fixed to the outside of the second water pipe 15 and the third water pipe 17. The top ends of the pair of third limiting rods 38 are fixed to a fixing plate 39. The top end of the fixing plate 39 is fixed to a telescopic rod 40. The output end of the telescopic rod 40 passes through the fixing plate 39 and is fixed to the top end of the sliding plate 37.

[0049] When the first and second electrical contacts 35 and 36 are in contact, the external controller receives information from the first and second electrical contacts 35 and 36 and controls the telescopic rod 40 to operate. The telescopic rod 40 drives the sliding plate 37 to move upward along the third limit rod 38. During the movement of the sliding plate 37, the connecting pipe 16 moves upward simultaneously. At this time, the connection between the second water pipe 15 and the third water pipe 17 will be broken, and the water source cannot enter the interior of the third water pipe 17 through the second water pipe 15. When the first and second electrical contacts 35 and 36 are separated, the external controller will control the telescopic rod 40 to reset, which will drive the connecting pipe 16 to descend, so that the second water pipe 15 and the third water pipe 17 are reconnected. The water source can then enter the interior of the third water pipe 17 through the second water pipe 15 and the connecting pipe 16, thus improving the automation level of the device.

[0050] like Figure 8 and Figure 10 As shown, the inner wall of the guide square tube 12 is fixed with an inclined block 41. The inclined block 41 is designed as a "right triangle". The right-angled side of the "right triangle" is located at the bottom end of the bottom tube 11. Both ends of the connecting tube 16 are fixed with rubber gaskets. The rubber gaskets are used to increase the sealing performance when the connecting tube 16 is connected to the second water pipe 15 and the third water pipe 17.

[0051] The right-angled triangle design of the inclined block 41 facilitates the flow of algae-eating insects out of the guide square tube 12. When the insects are on the inclined surface of the inclined block 41, the impact of the water flow accelerates their flow out. The rubber pads at both ends of the connecting pipe 16 increase the sealing between the connecting pipe 16 and the second water pipe 15 and the third water pipe 17, preventing water from flowing out from the connection points at both ends of the connecting pipe 16.

[0052] A process for releasing zooplankton into rivers for river management, comprising the following steps:

[0053] S1. First, pour the algae-eating insects along with the water source into the feeding box 6 through the feed inlet 7, and add trace elements suitable for the growth of algae-eating insects into the feeding box 6. The solenoid valve at the bottom of the feeding box 6 is in the closed state.

[0054] S2. Then move the delivery box 6 to the designated river, place the pallet 1 on the riverbank, start the cylinder 4, and when the cylinder 4 is running, it will drive the delivery box 6 to move towards the center of the river.

[0055] S3. Place one end of the mixing mechanism in the river and start the mixing mechanism. The mixing mechanism will draw water from the river and the water will enter the interior of the first connecting box 9. Finally, the water source will be sprayed into the interior of the delivery box 6 through the nozzle 8.

[0056] S4. The sprayed water creates a water vortex inside the injection tank 6, accelerating the mixing of trace elements inside the injection tank 6.

[0057] S5 also disperses the algae-eating insects, preventing them from accumulating in one place inside the distribution box 6 and causing uneven distribution in subsequent distributions.

[0058] Working principle: First, the algae-eating insects, along with the water source, are poured into the distribution box 6 through the inlet 7. Trace elements suitable for the growth of the algae-eating insects are added to the inside of the distribution box 6. The solenoid valve at the bottom of the distribution box 6 is closed. Then, the distribution box 6 is moved to the designated river, the tray 1 is placed on the riverbank, and the cylinder 4 is activated. The operation of the cylinder 4 moves the distribution box 6 towards the center of the river. However, the existing distribution device design is not precise enough, resulting in uneven distribution of the algae-eating insects during the distribution process. This may lead to localized over-distribution or under-distribution, affecting the river's ecological restoration effect. During the distribution process, trace elements tend to accumulate at the bottom of the distribution box, preventing even distribution to the area where the algae-eating insects are located. To address the aforementioned problem of hindering the reproduction of algae-eating insects, this embodiment of the invention places one end of the mixing mechanism in a river and activates it. The mixing mechanism draws water from the river, which then enters the first connecting box 9. Finally, the water is sprayed into the distribution box 6 through nozzle 8. The sprayed water creates a vortex within the distribution box 6, accelerating the mixing of trace elements and simultaneously dispersing the algae-eating insects. This prevents the insects from accumulating in one place and causing uneven distribution during subsequent distribution. It should be noted that during the water flow within the distribution box 6, the water source remains below the inlet 7, thus preventing the water and algae-eating insects from accumulating together. The water displaces from the inside of the feeding box 6 through the inlet 7. When water flows through the first connecting box 9, it drives the regulating mechanism, which in turn causes the bottom pipe 11 to rotate repeatedly, thus causing the guide square pipe 12 to swing back and forth. At this time, opening the solenoid valve at the bottom of the feeding box 6 allows the water and algae-eating insects inside to enter the bottom pipe 11 and finally flow into the designated river through the guide square pipe 12. The continuous swinging of the guide square pipe 12 adjusts the feeding area of ​​the water and algae-eating insects, preventing over- or under-feeding in certain areas. The inlet of the water pump 13 is placed in the river, and the pump is started, drawing water from the river into the first water pipe 14. Inside, water from the first water pipe 14 enters the second water pipe 15 through the first connecting box 9. Finally, water from the second water pipe 15 enters the nozzle 8 through the connecting pipe 16 and the third water pipe 17. The nozzle 8 sprays water into the dispensing box 6, thus dispersing algae-eating insects and trace elements. When water from the first water pipe 14 enters the first connecting box 9, it impacts one side of the impeller 18, forcing it to rotate. This rotation of the impeller 18 drives the support rod 19 to rotate, which in turn causes the side plate 20 to rotate around the support rod 19. The rotation of the side plate 20 then drives the slider 21 to rotate along the inside of the straight groove 22. During this movement, the slider 21...This will cause the straight groove 22 to reciprocate laterally. It should be noted that the movement distance of the straight groove 22 will not exceed the length of the second limit rod 24. When the straight groove 22 reciprocates, it will cause the rack 23 fixed at its top to reciprocate. The movement of the rack 23 will cause the first spur gear 26 to rotate. The rotation of the first spur gear 26 will then drive the bottom tube 11 to reciprocate through the second spur gear 28. The bottom tube 11 will eventually drive the guide square tube 12 to reciprocate around the bottom tube 11 as the circumference point. At this time, when the algae-eating insects and water inside the release box 6 enter the guide square tube 12 through the bottom tube 11, the guide square tube 12 will continuously swing back and forth, evenly distributing the algae-eating insects and water in different areas of the river. When the water level inside the release box 6... When the water level is halfway down or lower, if the nozzle 8 creates an air vortex in the water source inside the dispensing tank 6, causing the water to flow rapidly, this water flow environment may harm the algae-eating insects. To solve the above problem, in the initial state of use, the water source inside the dispensing tank 6 supports the float 29 to float. When the solenoid valve at the bottom of the dispensing tank 6 is opened, the water level inside the dispensing tank 6 will drop. Since the float 29 is made of polyurethane foam and has a certain weight, the float 29 will drop along with the water level and remain level with the water level. It should be noted that the speed at which the water source flows out of the dispensing tank 6 is faster than the speed at which the water source enters through the nozzle 8. When the water level drops to halfway down, the float 29 drives the first electrical contact plate 35 to drop, which is exactly the same as the second electrical contact plate 35. When the first contact plate 36 is in contact with the second contact plate 36, the float plate 29 should descend to its maximum distance above the nozzle 8. At this time, the external controller receives information from the contact plate 35 and the second contact plate 36 that they are in contact, and controls the moving mechanism to operate. The moving mechanism will drive the connecting pipe 16 to move upward, thereby disconnecting the connection between the connecting pipe 16 and the second water pipe 15 and the third water pipe 17. When the connecting pipe 16 is above the second water pipe 15, the moving mechanism stops. At this time, the water source inside the second water pipe 15 cannot enter the nozzle 8 through the third water pipe 17, thus preventing the nozzle 8 from still spraying when the water level is too low. The nozzle 8 is then stopped, preventing the water sprayed from the nozzle 8 from harming algae-eating insects. The structural design allows for the control of the nozzle 8's activation and deactivation based on the actual water level, ensuring careful use of the nozzle 8 to prevent adverse effects on the algae-eating insects and improving the safety of the device's operation. When it is necessary to add water and algae-eating insects to the distribution tank 6 again, first pull the end of the nylon rope 34 away from the float 29. The force on the nylon rope 34 will cause it to move upwards along the second sprocket 32 ​​and the first sprocket 30. During this upward movement, the first electrical contact plate 35 simultaneously disengages from the second electrical contact plate 36. At this point, the external controller receives the signal indicating the disengagement of the first and second electrical contact plates 35 and 36, and controls the connecting pipe 16 to move downwards to reset, reconnecting the second water pipe 15 and the third water pipe 17.When the float 29 moves above the connection between the inlet 7 and the delivery box 6, algae-eating insects and water can be added to the delivery box 6 through the inlet 7. Then, the nylon rope 34 is released, and the water inside the delivery box 6 will again support the float 29, allowing for repeated execution of the above actions. When the first and second electrical connectors 35 and 36 are in contact, the external controller receives information from the first and second electrical connectors 35 and 36, controlling the telescopic rod 40 to operate. The telescopic rod 40 drives the sliding plate 37 to move upwards along the third limit rod 38. During the movement of the sliding plate 37, the connecting pipe 16 moves upwards simultaneously. At this point, the connection between the second and third water pipes 15 is broken, preventing water from entering the third water pipe through the second pipe 15. Inside water pipe 17, when the first and second electrical connectors 35 and 36 disengage, the external controller will control the telescopic rod 40 to reset, causing the connecting pipe 16 to descend and reconnect the second and third water pipes 15 and 17. Water can then flow through the second water pipe 15 and connecting pipe 16 into the third water pipe 17, improving the automation level of the device. The right-angled triangle design of the inclined block 41 facilitates the flow of algae-eating insects out of the guide square tube 12. When on the inclined surface of the inclined block 41, the impact of the water flow accelerates the outflow of the algae-eating insects. The rubber gaskets at both ends of the connecting pipe 16 increase the sealing between the connecting pipe 16 and the second and third water pipes 15, preventing water from flowing out from the connection points of the connecting pipe 16.
