Description

[0001] The application is based on the application number 2024109786579, the application date is July 22, 2024, and the invention name is: a free-moving algae cleaning device TECHNICAL FIELD

[0002] The present application relates to the technical field of environmental protection equipment, in particular to an algae cleaning device with corrected balance. BACKGROUND

[0003] With the acceleration of social industrialization, a large amount of nutrients such as nitrogen and phosphorus enters natural water bodies, causing water eutrophication, which stimulates the growth of algae. A large amount of algae consumes oxygen in water, disturbs the ecological system, and may also release toxins to pollute human drinking water sources.

[0004] Traditional cyanobacterial bloom control can use physical or chemical methods. To safely and efficiently remove algae, ultrasonic waves have been used to remove algae by placing algae removal equipment in water and using the various effects (such as cavitation effect, mechanical effect, and free radical oxidation effect) generated by the ultrasonic waves propagating in water to destroy the pseudo-vacuoles of microalgae cells, leading to apoptosis of algae.

[0005] Chinese patent (patent number CN117569282A) discloses an algae cleaning device with corrected balance. High-pressure gas is delivered to the underwater gas injection pipe through the gas delivery pipe, and the gas is injected out, so that the algae removal device is moved under the reaction force of water. However, the center of gravity of the entire algae removal device is located above, and the gas injection pipe is located below the floating box, so that the algae removal device is prone to tilting when the gas pump power is increased and the algae removal device moves quickly. In addition, there are many algae on the surface of the lake, and the algae removal device will push the algae on the moving track when it moves to other water areas. The accumulation of the pushed algae will cause an obstruction force in front of the algae removal device, and the obstruction force of the algae is located above the water surface, while the gas injection pipe is located underwater, that is, the resistance of the algae to the algae removal device is relatively higher than the gas injection pipe. Therefore, the algae removal device is prone to overturning and sinking into the water during the process of quick movement and tilting. SUMMARY

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] Please refer to Figure 1 The present embodiment provides a balanced correction algae cleaning device, which comprises a protective cover 1, an algae removal mechanism installed on the protective cover 1, the algae removal mechanism comprising an ultrasonic assembly 2 arranged in the protective cover 1 and a warning light 10 and a signal transceiver antenna 11 arranged on the protective cover 1, a floating tank 3 arranged at the bottom of the protective cover 1, and a controller 9 arranged in the protective cover 1.

[0042] The ultrasonic assembly 2 comprises a PLC, an ultrasonic controller (model: RLC-UC100 of Hangzhou Ruili Ultrasonic Technology Co., Ltd.), a data acquisition and transmission module, and an ultrasonic transducer (model: RLC-UC100 of Hangzhou Ruili Ultrasonic Technology Co., Ltd., water action distance about 150-200 m).

[0043] In addition, the algae removal device of the present embodiment is provided with a GPS module 12 for determining the current position of the algae removal device in real time, so as to track the position of the device, and facilitate the understanding of the driving position and the distance from the target water area.

[0044] When the algae removal work is needed in a river or lake, the algae removal device is placed in the area to be removed. Due to the presence of the floating box 3, the protective cover 1 floats on the water surface and is not sunk to the bottom of the water, facilitating the signal receiving and sending of the signal transceiving antenna 11. After the signal transceiving antenna 11 receives the signal, the electric signal is transmitted to the controller 9, the controller 9 transmits the electric signal to the ultrasonic assembly 2, and the ultrasonic assembly 2 emits ultrasonic waves to remove the algae in the target water area.

[0045] Please refer to Figure 1 and Figure 9 for the convenience of monitoring the algae density of the target water area. It also includes a monitoring assembly installed at the bottom of the floating box 3, which includes a chlorophyll a sensing electrode 13 (model: OSA-ChlA of Hangzhou Naqing Optoelectronic Technology Co., Ltd.) and a blue-green algae sensing electrode 14 (model: OSA-Cyano of Hangzhou Naqing Optoelectronic Technology Co., Ltd.) fixedly installed on the floating box 3. In the present embodiment, the chlorophyll a sensing electrode 13 and the blue-green algae sensing electrode 14 are immersed below the water surface. The chlorophyll a concentration of the target water body is monitored in real time by the chlorophyll a sensing electrode 13, and the algae density of the target water body is monitored in real time by the blue-green algae sensing electrode 14. When the algae density of the target water area decreases to a set value, the monitoring assembly sends an electric signal to the controller 9, and the controller 9 controls the signal transceiving antenna 11 to send a signal for prompting the staff to replace the algae removal device in time to clean the water area. At the same time, the algae density of the water area in the current range can also be monitored by the monitoring assembly to understand the algae density of the current water area in real time.

[0046] Please refer to Figure 1 and Figure 9 to reduce the influence and damage of water impurities (such as fish, driftwood flowing with water, etc.) on the monitoring assembly. An electrode protective cover 15 is installed outside the monitoring assembly, which is fixedly installed on the floating box 3, and a plurality of water inlet holes 16 are formed on the surface of the electrode protective cover 15. The water in the target water area can flow to the monitoring assembly through the water inlet holes 16 for detection, thereby reducing the influence and damage of water animals or impurities on the monitoring assembly.

[0047] When the algae removal device finishes removing the algae in an area, the water area needs to be replaced. However, due to the large coverage area of rivers or lakes, it is not only time-consuming and laborious to move by ship and manually, but also the moving of the ship will pollute the cleaned water area.

[0048] Please refer to Figure 1 and Figure 2To solve the above technical problems, the floating box 3 is provided with a moving mechanism 4 for driving the floating box 3 to move. The moving mechanism 4 comprises a jet pipe 43 located underwater, an air pump 41 located on water, and an air supply pipe 42 connecting the air pump 41 and the jet pipe 43, and further comprises a driving unit 44 for driving the jet pipe 43 to rotate circumferentially, wherein the circumferential rotation is substantially horizontal plane circumferential rotation. The air pump 41 is electrically connected to the controller 9, and the driving unit 44 is electrically connected to the controller 9. The air pump 41 is preferably an electric air pump, which has the functions of air charging and air pumping.

[0049] When the algal density of the target water area decreases to a set value, the monitoring assembly sends an electrical signal to the controller 9, and the controller 9 controls the signal transceiver antenna 11 to send a signal for prompting the staff to replace the algae removal device in time to clean the water area, so that the staff sends a signal, the signal transceiver antenna 11 receives the signal, and the electrical signal is transmitted to the controller 9, and the controller 9 controls the air pump 41 to start working, thereby delivering gas to the outside, and the high-pressure gas is delivered to the jet pipe 43 through the air supply pipe 42. Since the jet pipe 43 is located underwater, the jet pipe 43 will spray gas underwater, and the direction of the sprayed gas is horizontal, so that the jet pipe 43 will move in the opposite direction of the jet under the action of the water, and since the jet pipe 43 is installed on the floating box 3, the floating box 3 and the protective cover 1 upward of the floating box 3 will move together on the water, thereby realizing the movement of the algae removal device;

[0050] During the movement of the algae removal device, due to the instability of the movement in the water flow, the route deviation may easily occur when moving to the target water area, so that when the staff on the shore observes that the algae removal device deviates from the route or automatically detects according to the data transmitted by the GPS module 12, the signal can be continuously transmitted to the signal transceiver antenna 11, the signal transceiver antenna 11 transmits an electrical signal to the controller 9, the controller 9 controls the driving unit 44, the driving unit 44 controls the jet pipe 43 to rotate, thereby adjusting the jet direction of the jet pipe 43 in the water, and adjusting the moving path of the entire algae removal device to reach the specified area.

[0051] Since the area of the lake is large, and the radiation treatment range of the device is 250m-400m around, after two to three days, the current water area is treated, and the algae removal device needs to be moved to the adjacent water area or a remote water area. Due to the long distance, the power of the air pump 41 is often increased in the early stage, thereby increasing the jet flow and accelerating the moving speed of the algae removal device, and then accelerating the efficiency, and when approaching the target water area, the moving speed of the algae removal device is slowed down to facilitate the stay at the specified position.

[0052] The gas pump 41, the ultrasonic assembly 2, the protective cover 1 and other equipment are on the upper side of the floating box 3, and the floating box 3 is a hollow body, so that the center of gravity of the entire algae removal device is on the upper side, and the air jet pipe 43 is located below the floating box 3, so that in the process of increasing the power of the gas pump 41 and the rapid movement of the algae removal device, the algae removal device is prone to tilting. When the algae removal device moves to other water areas, it will push the algae on the moving track. With the accumulation of the pushed algae, an obstruction force will be caused to the front of the moving algae removal device. The obstruction force of the algae is located on the water surface, that is, the resistance of the algae to the algae removal device is relatively high to the air jet pipe 43. In the process of rapid movement and tilting of the algae removal device, the direction of the air jet of the air jet pipe 43 will also change, so that the algae removal device is prone to overturning and sinking into the water.

[0053] Please refer to Figure 10 and Figure 11 To solve the above technical problems. The air jet pipe 43 is fixedly installed with a cylinder 18, the axis of the cylinder 18 is perpendicular to the axis of the air jet pipe 43, the cylinder 18 is rotatably installed with a sealing cylinder 19, the side of the cylinder 18 away from the outlet of the air jet pipe 43 is provided with a gas exchange hole 20, the side of the sealing cylinder 19 is provided with a gas guide hole 21 matched with the gas exchange hole 20, the lower side of the cylinder 18 is fixedly installed with a correction pipe 22 extending to the lower side of the air jet pipe 43, the lower side of the sealing cylinder 19 is provided with a gas transmission hole 27 communicating with the correction pipe 22, and the side of the sealing cylinder 19 is installed with a horizontal detection mechanism 23. When the axis of the air jet pipe 43 is parallel to the horizontal plane, the gas exchange hole 20 and the gas guide hole 21 are misaligned with each other, and the sealing cylinder 19 blocks the gas exchange hole 20. When the axis of the air jet pipe 43 is inclined to the horizontal plane, the horizontal detection mechanism 23 drives the sealing cylinder 19 to rotate, and the gas exchange hole 20 and the gas guide hole 21 are communicated.

[0054] In the process of rapid movement of the algae removal device in a large amount of air jet of the air jet pipe 43, the algae removal device tilts, so that the direction of the air jet of the air jet pipe 43 changes, so that the axis of the air jet pipe 43 is inclined to the horizontal plane. At this time, the horizontal detection mechanism 23 drives the sealing cylinder 19 to rotate, so that the gas guide hole 21 on the sealing cylinder 19 is communicated with the gas exchange hole 20 on the cylinder 18, so that part of the high-pressure gas of the air jet pipe 43 passes through the gas exchange hole 20, the gas guide hole 21 and the gas transmission hole 27 to reach the correction pipe 22. Since the correction pipe 22 is located below the air jet pipe 43, the gas is jetted from the lower side of the air jet pipe 43, so as to provide an upward thrust for the air jet pipe 43, so that the air jet pipe 43 inclined to the horizontal plane receives an upward thrust, that is, an upward thrust appears on the opposite side of the tilted algae removal device, which assists the algae removal device to correct and stabilize, and reduces the tilting amplitude.

[0055] Please refer to Figure 11 and Figure 12The horizontal detection mechanism 23 comprises an arc-shaped protective shell 231 fixedly installed on the air jet pipe 43, a connecting rod 232 fixedly installed on the shaft side of the sealing cylinder 19, a transmission rod 233 fixedly installed on the circumferential side of the connecting rod 232 and located in the arc-shaped protective shell 231, and a counterweight 234 fixedly installed on the side of the transmission rod 233 away from the connecting rod 232, and the transmission rod 233 is perpendicular to the horizontal plane.

[0056] When the algae removal device is tilted, the axis of the air jet pipe 43 is inclined relative to the horizontal plane. Due to the counterweight 234 under the action of gravity, the transmission rod 233 is always kept in a vertical downward state. Therefore, during the process that the air jet pipe 43 is inclined relative to the horizontal plane, the transmission rod 233 drives the sealing cylinder 19 to rotate through the connecting rod 232, so that the air guide hole 21 on the sealing cylinder 19 is in communication with the air exchange hole 20 on the cylinder 18.

[0057] Due to different air jet speeds of the air jet pipe 43 or different resistances suffered by the algae removal device on the water surface, the tilting angle of the algae removal device during movement is also different. If the tilting angle of the algae removal device is high and the air flow rate of the air jet pipe 43 is low, the correction effect on the algae removal device is poor. If the tilting angle of the algae removal device is low and the air flow rate of the air jet pipe 43 is high, the correction of the algae removal device is excessive, which leads to large shaking and poor stability of the algae removal device during movement.

[0058] Please refer to Figure 10 and Figure 13 To solve the above technical problems, a plurality of air exchange holes 20 are formed on the circumferential side of the cylinder 18 along the axis direction of the cylinder 18, and a plurality of air guide holes 21 are helically formed on the circumferential side of the sealing cylinder 19. With the increase of the rotation angle of the sealing cylinder 19 relative to the cylinder 18, the number of the air guide holes 21 in communication with the air exchange holes 20 increases.

[0059] With the gradual increase of the tilting angle of the algae removal device, the rotation angle of the sealing cylinder 19 relative to the cylinder 18 driven by the horizontal detection mechanism 23 also increases, so that the number of the air guide holes 21 on the sealing cylinder 19 in communication with the air exchange holes 20 also increases. In turn, the air flow in the air jet pipe 43 entering the correction pipe 22 through the air exchange holes 20, the air guide holes 21 and the air transmission holes 27 also increases, so that the upward thrust of the water on the air jet pipe 43 increases. Therefore, the greater the tilting angle of the algae removal device, the greater the upward thrust, which improves the stability of the algae removal device.

[0060] Please refer to Figure 11 and Figure 12 To reduce the backflow of the water from the correction pipe 22, the sealing plate 24 is rotatably installed on the inner wall of the correction pipe 22, the stop block 25 is fixedly installed on the inner wall of the correction pipe 22 and located on the upper side of the sealing plate 24, the elastic member 26 for driving the sealing plate 24 and the stop block 25 to abut is fixedly installed in the correction pipe 22, and the elastic member 26 is a volute spring.

[0061] When there is no gas flow in the correction pipeline 22, the sealing plate 24 is in abutment with the stopper 25 under the action of the elastic member 26, thereby sealing the correction pipeline 22 and preventing external water flow from entering the correction pipeline 22. When the correction pipeline 22 is ventilated, the gas pressure pushes away the sealing plate 24, so that the gas flow is sprayed into the water through the lower side of the correction pipeline 22.

[0062] Since the jet pipeline 43 is located in the water, the water will enter the inside of the jet pipeline 43 through the jet holes of the jet pipeline 43. Due to the hydraulic balance, there will be water in the gas delivery pipeline 42 as well. In the untreated water area, there are a large number of water algae in the water, so the water algae or impurities in the water will possibly flow into the jet pipeline 43 and the gas delivery pipeline 42 along with the water flow, thereby easily causing the blockage of the jet pipeline 43 and the gas delivery pipeline 42, or partial blockage, affecting the flow of the gas, and further affecting the moving efficiency of the algae removal device, and even causing the damage of the moving mechanism 4.

[0063] Please refer to Figure 1 、 Figure 2 and Figure 5 , to solve the above technical problems. A plug 45 for blocking the outlet is slidably arranged inside the jet pipeline 43 at the outlet. The plug 45 is a circular truncated cone. A moving rod 46 is fixedly installed on one side of the plug 45. A guide disc 47 is sleeved on the surface of the moving rod 46. The guide disc 47 is fixedly connected with the inner wall of the jet pipeline 43. A pressing disc 48 is fixedly installed on the side of the moving rod 46 away from the plug 45. A first spring 49 is fixedly installed between the pressing disc 48 and the guide disc 47. In the initial state, the plug 45 is in abutment with the edge of the outlet, and the first spring 49 is in the compressed state.

[0064] In the initial state, under the elastic force of the first spring 49, the plug 45 is in abutment with the edge of the outlet, thereby blocking the outlet and avoiding the water flow from flowing into the inside of the jet pipeline 43. When the algae removal device needs to move to a position, the air pump 41 starts to work, and high-pressure gas is delivered to the inside of the jet pipeline 43 through the gas delivery pipeline 42. Although the outlet of the jet pipeline 43 is blocked by the plug 45, the pressure in the jet pipeline 43 is increased with the continuous delivery of the high-pressure gas to the inside of the jet pipeline 43, thereby pushing the plug 45 to move and separate from the edge of the outlet. At this time, the gas in the jet pipeline 43 is sprayed out through the gap between the plug 45 and the outlet, thereby realizing the movement of the algae removal device.

[0065] Wherein, the movement of the plug 45 will drive the movement of the moving rod 46, the movement of the moving rod 46 will drive the extrusion of the pressure plate 48 to the first spring 49, so as to increase the elastic potential energy accumulated in the first spring 49. When the gas conveying pipe 42 stops conveying gas, the pressure in the gas jet pipe 43 gradually decreases. Under the action of the elastic force of the first spring 49, the plug 45 gradually approaches the edge of the outlet of the gas jet pipe 43 until the plug 45 abuts against the edge of the outlet of the gas jet pipe 43, thereby isolating the outside water from the inside of the gas jet pipe 43 and preventing the water from flowing back into the gas jet pipe 43.

[0066] It should be noted that the first spring 49 is prone to radial bending when compressed, resulting in the release of the elastic potential energy accumulated in the first spring 49. Too much entanglement of waterweeds and too large surface attachment are not conducive to recovery, and too large occupation of area is not convenient for placement.

[0067] Please refer to Figure 5 To solve the above technical problems, a guide rod 410 is fixedly installed on one side of the pressure plate 48 and penetrates the first spring 49, and a guide hole 411 is formed in the guide disc 47 for the guide rod 410 to penetrate.

[0068] Since the guide rod 410 penetrates the first spring 49, if the first spring 49 is bent radially during compression, the first spring 49 will come into contact with the guide rod 410, thereby limiting the bending of the first spring 49 and ensuring the accumulation of elastic potential energy in the first spring 49.

[0069] When the plug 45 is separated from the edge of the outlet and the gap between the plug 45 and the outlet is open to the outside, the gas will be dispersed and sprayed from around the plug 45, so that part of the reaction force of the water is consumed after the gas contacts the water, thereby improving the gas spraying pressure and the reaction force of the water on the algae removal device.

[0070] Please refer to Figure 5 The gas jet pipe 43 is fixedly installed with an accumulation cover 412 on the side away from the gas conveying pipe 42. The accumulation cover 412 is a hollow circular truncated cone. Air holes are formed in the two sides of the accumulation cover 412. The inner diameter of the cross section of the accumulation cover 412 decreases away from the gas jet pipe 43.

[0071] When the gas is sprayed through the gap between the plug 45 and the outlet of the gas jet pipe 43, the plug 45 is a circular truncated cone, so that the gas is sprayed at an angle inclined to the axis of the plug 45. When the gas contacts the inner wall of the accumulation cover 412, the inner diameter of the cross section of the accumulation cover 412 decreases away from the gas jet pipe 43, so that the gas sprayed into the accumulation cover 412 changes its flow direction when it contacts the inner wall of the accumulation cover 412 and moves towards the middle of the accumulation cover 412, and then is sprayed into the water through the air holes in the accumulation cover 412, thereby improving the spraying intensity of the gas.

[0072] Please refer to Figure 2And Figure 3 The driving unit 44 comprises a first stepping motor 441 arranged in the protective cover 1, a gear 442 fixedly installed on an output shaft of the first stepping motor 441, a gear ring 443 fixedly installed on a side surface of the air feeding pipe 42 and engaged with the gear 442, the air feeding pipe 42 fixedly connected with the air pump 41, the air feeding pipe 42 fixedly connected with the air jet pipe 43, the first stepping motor 441 electrically connected with the controller 9, the air feeding pipe 42 and the air pump 41 both arranged to rotate with the floating body tank 3, and the air feeding pipe 42 and the air pump 41 both arranged to rotate with the protective cover 1.

[0073] When it is needed to adjust the moving track of the algae removing device, the operator sends a signal which is received by the signal transceiving antenna 11, the signal transceiving antenna 11 transmits the signal to the controller 9, the controller 9 controls the first stepping motor 441 to drive the gear 442 to rotate, the gear 442 drives the gear ring 443 to rotate, the gear ring 443 drives the air feeding pipe 42 to rotate, and further drives the air jet pipe 43 to rotate, so as to realize the adjustment of the air jet direction and further adjust the moving track of the algae removing device.

[0074] In order to further adjust the gravity center of the algae removing device and improve the stability of the algae removing device when moving, the air jet pipe 43 comprises an outer pipe 431 and a plurality of inner pipes 432 (only one inner pipe 432 is shown in the drawing), the outer pipe 431 is sleeved on the surface of the inner pipe 432, the adjacent inner pipes 432 are sleeved on each other, and the outer pipe 431 and the inner pipe 432 and the adjacent inner pipes 432 are provided with guiding units, which guide the adjacent pipes to slide linearly, the inner pipe 432 with the smallest inner diameter is fixedly connected with the air feeding pipe 42 on one side, and the correction pipe 22 is fixedly installed on the outer pipe 431.

[0075] The guiding unit comprises a guide block and a guide groove, the guide block is fixedly installed on the inner wall of the pipe with larger inner diameter between the adjacent pipes, the guide groove is opened on the outer side of the pipe with smaller inner diameter, and the guide block is slidingly arranged in the guide groove.

[0076] The gas in the gas pump 41 is delivered to the inner tube 432 with the smallest inner diameter through the gas delivery pipeline 42, so that the internal pressure of the gas jet pipeline 43 is increased, and at this time, the plug 45 blocks the gas jet port of the gas jet pipeline 43, that is, the plug 45 blocks the gas jet outlet of the outer tube 431, so that under the condition that the internal pressure gradually increases, the outer tube 431 will gradually slide along the axis of the inner tube 432, and the adjacent inner tubes 432 will also slide and make linear sliding under the guidance of the guide unit, thereby increasing the internal space of the gas jet pipeline 43, until the outer tube 431 and the inner tube 432 move to the maximum displacement, that is, the gas jet pipeline 43 is elongated to the maximum length, at this time, because the outer tube 431 and the inner tube 432 have no further extension, the internal pressure of the gas jet pipeline 43 gradually increases to push away the plug 45, thereby realizing the gas jet work of the gas jet pipeline 43, wherein the elongation operation of the gas jet pipeline 43, on the one hand, increases the contact area of the algae removal device bottom with water, improves the bottom range, reduces the gravity center of the algae removal device, makes the algae removal device move more stably, on the other hand, the elongation length of the gas jet pipeline 43 increases the internal space, which will increase the buoyancy of the algae removal device, and at the same time, when the algae removal device moves, it will float up, reducing the flow of water splashing into the protective cover 1 when moving, damaging the equipment;

[0077] When the algae removal device moves to the specified position, at this time, the gas pump 41 is used to extract air, at this time, during the air extraction process of the gas pump 41, the internal pressure of the gas jet pipeline 43 decreases, so that the plug 45 blocks the gas jet port again, at this time, the gas jet pipeline 43 is difficult to absorb gas from the outside, and the internal pressure will gradually decrease, so that the outer tube 431 and the inner tube 432 slide relative to each other again, and the gas jet pipeline 43 is contracted until it returns to the initial position, thereby on the one hand, by reducing the length of the gas jet pipeline 43, the attachment area of the water algae in the lake to the surface of the gas jet pipeline 43 is reduced, and the cleaning difficulty is reduced, on the other hand, it is convenient to recover the algae removal device, because if the length of the bottom gas jet pipeline 43 is too large, the range is too wide, it is not convenient to salvage and transport, and the occupied area is large when placed.

[0078] During the movement of the algae removal device caused by the gas jet pipeline 43 jetting gas, the gas jet pipeline 43 continuously jets gas in the water, so that during the rotation of the gas jet pipeline 43 driven by the driving unit 44, on the one hand, the resistance in the water is large, and the floating box 3 also floats on the water, when the gas jet pipeline 43 rotates relative to the floating box 3, the reaction force of the gas jet pipeline 43 on the floating box 3 will also make the floating box 3 receive a rotating torque, so that the floating box 3 rotates on the water, so that if the rotating angle of the gas jet pipeline 43 is too large and the speed is too fast, the floating box 3 will also rotate relative to the water surface, so that the actual rotating angle of the gas jet pipeline 43 relative to the floating box 3 is smaller than the predicted angle, which is easy to cause errors during trajectory correction;

[0079] On the other hand, in the process of correcting the trajectory, the jet pipe 43 is always jetting outward, so when the moving trajectory of the algae removal device is corrected, there will be a large arc, the correction range is too large, and the correction time is too long.

[0080] Please refer to Figures 4-6 To solve the above technical problems, the gas supply pipe 42 and the jet pipe 43 are connected through the adjusting mechanism 5, the adjusting mechanism 5 includes a cylindrical shell 51, the shaft side of the cylindrical shell 51 is fixedly connected with the shaft side of the gas supply pipe 42, the jet pipe 43 has at least four, the four jet pipes 43 are uniformly distributed on the side of the cylindrical shell 51, the cylindrical shell 51 is provided with a through hole 52 communicating with the jet pipe 43, the cylindrical shell 51 is rotatably installed with a sealing cover 53, the sealing cover 53 is a cylinder with an open upper end, the sealing cover 53 is provided with a gas outlet hole 54 on the side, and the sealing cover 53 is provided with a second stepping motor 55 for driving the sealing cover 53 to rotate axially around the cylindrical shell 51, when the gas outlet hole 54 on the sealing cover 53 communicates with one of the through holes 52, the sealing cover 53 seals the other through holes 52.

[0081] When the moving trajectory of the algae removal device needs to be corrected, if the deviation angle is too large, or the moving displacement is too large and needs to be returned, a signal can be sent to the signal transceiver antenna 11 at this time, the signal transceiver antenna 11 receives the signal, transmits the electric signal to the controller 9, the controller 9 controls the second stepping motor 55 to drive the sealing cover 53 to rotate, according to the judgment of the staff, the gas outlet hole 54 on the sealing cover 53 is rotated to the position of the jet pipe 43 with smaller adjusting angle, so that the jet is carried out through another jet pipe 43, so as to change the jet direction in the water and adjust the moving trajectory of the algae removal device faster without rotating the jet pipe 43 by a large angle.

[0082] More specific working method is, for example, when the algae removal device moves too much and exceeds the target position, at this time, only need to rotate 180 degrees through the second stepping motor 55, that is, rotate the gas outlet hole 54 on the sealing cover 53 to the position of the jet pipe 43 opposite to the current jet pipe 43, so that the jet direction in the water is directly opposite, because the sealing cover 53 rotates in the cylindrical shell 51, so it is not affected by the resistance in the water, and the current method consumes less energy.

[0083] If there is a small trajectory deviation of 10 to 45 degrees, the angle of the jet pipe 43 currently jetting can be adjusted by the driving unit 44, which is more flexible and accelerates the correction rate.

[0084] In the process of moving the algae removal device in the lake, due to the movement of the water flow, the algae removal device may be moved, thereby quickly changing the control of the other jet pipe 43 on the algae removal device, that is, the air outlet hole 54 on the sealing cover 53 is communicated with the other perforations 52, at this time the communicated jet pipe 43 will be extended again and jet air outward, but when the jet pipe 43 is recovered, because the air outlet hole 54 on the sealing cover 53 is only communicated with one of the perforations 52, the originally extended jet pipe 43 cannot be retracted and remains in the extended state.

[0085] To solve the above technical problems, three one-way air inlet valves 56 are fixedly installed on the inner wall of the sealing cover 53, and a transmission hole 566 communicated with the one-way air inlet valve 56 is formed in the side wall of the sealing cover 53. When the air outlet hole 54 is communicated with one of the perforations 52, the three transmission holes 566 are also communicated with the other three perforations 52, that is, one transmission hole 566 is communicated with one perforation 52. When the air pump 41 inhales, the one-way air inlet valve 56 is opened, so that the air pump 41 can inhale all the jet pipes 43, so that each jet pipe 43 can be retracted.

[0086] Please refer to Figure 4 and Figure 7 , wherein the one-way air inlet valve 56 includes a valve column 561 fixedly installed on the inner wall of the sealing cover 53, a valve cover 562 installed on one side of the valve column 561, a positioning column 563 fixedly installed on the side of the valve cover 562 close to the valve column 561, a retainer ring 564 fixedly installed on the inner wall of the valve column 561, and a second spring 565 fixedly installed between the retainer ring 564 and the positioning column 563. In the initial state, the valve cover 562 abuts against the side wall of the valve column 561, and the second spring 565 is in a stretched state.

[0087] When the sealing cover 53 is in a suction negative pressure state, at this time the valve cover 562 moves away from the valve column 561 under the negative pressure state, so as to open the sealing of the valve column 561, so that the gas in the jet pipe 43 is sucked out through the perforations 52, the transmission holes 566 and the valve column 561, and the retraction of the jet pipe 43 is completed.

[0088] Please refer to Figure 2 and Figure 3 , wherein the floating body box 3 is provided with a through hole 6 for the air supply pipe 42 to pass through, and a plurality of ball bearings 7 for supporting the jet pipe 43 are installed on the side surface of the air supply pipe 42 and located in the inner wall of the through hole 6. Through the ball bearings 7, on the one hand, the friction between the air supply pipe 42 and the through hole 6 is reduced, and on the other hand, the air supply pipe 42 is supported.

[0089] Please refer to Figure 2 and Figure 8The positioning mechanism 8 is installed on the protective cover 1, and comprises a winding machine 81, a pull rope 82 and a positioning anchor 83. One end of the pull rope 82 is wound on the winding machine 81, and the other end is fixedly installed on the positioning anchor 83. The winding machine 81 is electrically connected with the controller 9.

[0090] When the algae-removing device is moved to the corresponding water area, the operator sends a signal to the signal transceiver antenna 11. The signal transceiver antenna 11 receives the signal and transmits an electric signal to the controller 9. The winding machine 81 is controlled by the controller 9 to release the pull rope 82, so that the positioning anchor 83 sinks into the water bottom, thereby positioning the algae-removing device. When the algae-removing device needs to be moved, the pull rope 82 is wound by the winding machine, and the positioning anchor 83 is pulled up, and then the algae-removing device is moved.

[0091] Please refer to Figure 1 In order to keep the algae-removing device sufficient and self-sufficient in power, the solar panel 17 is installed on the protective cover 1, and the battery is installed in the protective cover 1. The battery is electrically connected with the solar panel 17, and provides power for the controller 9.

[0092] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be included in the present application.
