Description

[0001] This application is based on application number 2024109786579, application date July 22, 2024, and the invention name is: A free-moving algae cleaning device Technical Field The invention relates to the technical field of environmental protection equipment, and in particular to an algae cleaning device capable of preventing rollover. Background Art

[0002] With the acceleration of the industrialization process, a large amount of nutrients such as nitrogen and phosphorus enter natural water bodies, causing eutrophication of water bodies and stimulating the growth of algae. A large amount of algae will consume oxygen in the water, disrupt the ecosystem, and may also release toxins to pollute human drinking water sources.

[0003] Traditionally, physical or chemical methods can be used to control blue algae blooms. In order to remove algae safely and efficiently, ultrasonic algae removal has begun to be used. By placing algae removal equipment in the water, the various effects (such as cavitation effect, mechanical effect and free radical oxidation effect, etc.) produced by the ultrasonic wave on the equipment during the propagation in the water are used to destroy the pseudo-cavitation of microalgae cells and cause apoptosis of algae.

[0004] A Chinese patent (patent number CN117569282A) discloses an anti-rollover algae cleaning device. High-pressure gas is delivered to the jet pipe through an air supply pipe to spray gas underwater, thereby realizing the movement of the algae removal device under the reaction force of the water. However, because the center of gravity of the entire algae removal device is upward, and the jet pipe is located below the float box, the algae removal device is prone to tilting when the air pump power is increased and the algae removal device moves rapidly. At the same time, there are many algae on the surface of the lake. When the algae removal device moves to other waters, it will push the algae on the moving track. As the pushed algae accumulate, it will cause an obstruction to the movement of the algae removal device. The obstruction of the algae is located on the water surface, while the jet pipe pushes it underwater, that is, the resistance of the algae to the algae removal device is relatively high relative to the jet pipe. In the process of the algae removal device moving rapidly and tilting, the algae removal device is prone to flipping and sinking into the water. Summary of the invention

At this time, the horizontal detection mechanism drives the sealing cylinder to rotate, so that the air guide holes on the sealing cylinder are connected with the air exchange holes on the cylinder, so that part of the high-pressure gas passing through the jet pipe will pass through the air exchange holes, the air guide holes and the air transfer holes to reach the correction pipe. Since the correction pipe is located at the lower side of the jet pipe, gas will be ejected from the lower side of the jet pipe, thereby providing an upward thrust for the jet pipe, so that the jet pipe in an inclined state relative to the horizontal plane is subjected to an upward thrust, that is, an upward thrust is applied to the opposite side of the tilted algae removal device, thereby assisting the algae removal device to be corrected smoothly, reducing the tilting amplitude, and thereby reducing the occurrence of rollover.

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 The present embodiment provides an algae cleaning device for preventing rollover, including a protective cover 1, an algae removal mechanism installed on the protective cover 1, the algae removal mechanism including an ultrasonic component 2 arranged in the protective cover 1, a warning light 10 and a signal transceiver antenna 11 arranged on the protective cover 1, a float box 3 is arranged at the bottom of the protective cover 1, and a controller 9 is arranged in the protective cover 1.

[0028] The ultrasonic component 2 includes a plc, an ultrasonic controller (model: Hangzhou Rayleigh Ultrasonic Technology Co., Ltd. RLC-UC100), a data acquisition and transmission module, and an ultrasonic transducer (model: Hangzhou Rayleigh Ultrasonic Technology Co., Ltd. RLC-UC100, the effective distance in water is about 150~200m).

[0029] In addition, the algae removal device of this embodiment is installed with a GPS module 12 for determining the current position of the algae removal device in real time to locate and track the device, so as to facilitate knowing the driving position and the distance to the target water area at any time.

[0030] When algae removal is required for rivers or lakes, the algae removal device is placed in the corresponding algae removal area. Due to the presence of the float box 3, the protective cover 1 floats on the water surface and does not sink to the bottom of the water, which facilitates the signal receiving and sending of the signal transceiver antenna 11. After the signal transceiver antenna 11 receives the signal, it transmits the electrical signal to the controller 9, and the controller 9 transmits the electrical signal to the ultrasonic component 2, which emits ultrasonic waves to remove algae from the target water area.

[0031] See also Figure 1 and Fig. 9 , in order to facilitate the monitoring of the algae density in the target water area. It also includes a monitoring component installed at the bottom of the float box 3, and the monitoring component includes a chlorophyll a sensor electrode 13 (model: OSA-ChlA of Hangzhou Naqing Optoelectronics Technology Co., Ltd.) and a blue-green algae sensor electrode 14 (model: OSA-Cyano of Hangzhou Naqing Optoelectronics Technology Co., Ltd.) fixedly installed on the float box 3. In this embodiment, the chlorophyll a sensor electrode 13 and the blue-green algae sensor electrode 14 are immersed below the water surface, and the chlorophyll a concentration of the target water body is monitored in real time by the chlorophyll a sensor electrode 13, and the algae density of the target water body is monitored in real time by the blue-green algae sensor electrode 14. When the algae density of the target water area drops to the set value, the monitoring component sends an electrical signal to the controller 9, and the controller 9 controls the signal transceiver antenna 11 to send a signal to prompt the staff to replace the algae removal device with the water area to be cleaned in time. At the same time, the algae density of the water area within the current range can be monitored by the monitoring component, and the algae density of the current water area can be understood in real time.

[0032] See also Figure 1 and Fig. 9In order to reduce the impact and damage of debris in the water (such as fish, floating wood flowing with the water flow, etc.) on the monitoring component. An electrode shield 15 is installed outside the monitoring component. The electrode shield 15 is fixedly installed on the float box 3, and a plurality of water inlet holes 16 are opened on the surface of the electrode shield 15. The water in the target water area can flow to the monitoring component through the water inlet holes 16 for detection, thereby reducing the impact and damage of animals or debris in the water on the monitoring component.

[0033] After the algae removal device has cleared the algae in an area, the water area needs to be changed. However, since rivers or lakes cover a large area, it is not only time-consuming and laborious to salvage and move them by ship or manual labor, but also the movement of ships will cause certain pollution to the cleaned water area.

[0034] See also Figure 1 and Figure 2 , in order to solve the above technical problems. A moving mechanism 4 for driving the floating box 3 to move is installed on the floating box 3. The moving mechanism 4 includes a jet pipe 43 located underwater, an air pump 41 and an air supply pipe 42 located above the water, wherein the air supply pipe 42 connects the air pump 41 and the jet pipe 43, and also includes a driving unit 44 for driving the jet pipe 43 to rotate circumferentially, wherein the circumferential rotation is roughly circumferential rotation on a horizontal plane, the air pump 41 is connected to the controller 9 by electrical signals, and the driving unit 44 is connected to the controller 9 by electrical signals. The air pump 41 is preferably an electric air pump, which has the functions of inflation and degassing.

[0035] When the algae density in the target water area drops to the set value, the monitoring component sends an electrical signal to the controller 9, and the controller 9 controls the signal transceiver antenna 11 to send a signal to prompt the staff to replace the algae removal device with the water area to be cleaned in time, so that the staff sends a signal, and the signal transceiver antenna 11 receives the signal, so that the electrical signal is transmitted to the controller 9, and the controller 9 controls the air pump 41 to start working, so as to transport gas to the outside, and transport the high-pressure gas to the jet pipe 43 through the air supply pipe 42. Because 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 under the reaction force of the water, the jet pipe 43 will be pushed to move in the opposite direction of the jet, and because the jet pipe 43 is installed on the float box 3, the float box 3 and the upward protective cover 1 of the float box 3 will move together on the water, thereby realizing the movement of the algae removal device; During the movement of the algae removal device, due to the unstable movement in the water flow, the route is easily deviated when moving to the target water area. Therefore, when the shore personnel observe that the algae removal device deviates from the route or the system automatically detects based on the data transmitted by the GPS module 12, it can continuously transmit signals to the signal transceiver antenna 11, and the signal transceiver antenna 11 transmits electrical signals to the controller 9. The controller 9 controls the drive unit 44, and the drive unit 44 controls the rotation of the jet pipe 43, thereby adjusting the jet direction of the jet pipe 43 in the water, thereby adjusting the moving path of the entire algae removal device to reach the designated area.

[0036] Since the lake area is large, and the radiation treatment range of this equipment is 250m-400m around, after two to three days, when the current water area is treated, the algae removal device needs to be moved to adjacent waters or farther waters. Due to the long distance, the power of the air pump 41 is often increased in the early stage to increase the jet flow rate, speed up the movement of the algae removal device, and thus increase the efficiency. When approaching the target water area, the movement speed of the algae removal device will be slowed down to facilitate staying at the designated location.

[0037] Because the air pump 41, ultrasonic component 2, protective cover 1 and other equipment are located on the upper side of the float box 3, and the float box 3 is a hollow body, the center of gravity of the entire algae removal device is on the upper side, and the jet pipe 43 is located below the float box 3. As a result, when the power of the air pump 41 is increased and the algae removal device moves rapidly, the algae removal device is prone to tilting. At the same time, there are many algae on the surface of the lake. When the algae removal device moves to other waters, it will push the algae on the moving trajectory. As the pushed algae accumulate, it will cause an obstruction to the movement of the algae removal device in front, and the obstruction of the algae is located on the water surface, that is, the resistance of the algae to the algae removal device is relatively high relative to the jet pipe 43. During the rapid movement and tilting of the algae removal device, the jet direction of the jet pipe 43 will also change, so that the algae removal device is prone to flipping and sinking into the water.

[0038] See also Fig.10 and Fig.11, in order to solve the above technical problems. A cylinder 18 is fixedly installed on the jet pipe 43, and the axis of the cylinder 18 is perpendicular to the axis of the jet pipe 43. A sealing cylinder 19 is rotatably installed in the cylinder 18. A ventilation hole 20 is provided on the side of the cylinder 18 away from the outlet of the jet pipe 43, and an air guide hole 21 adapted to the ventilation hole 20 is provided on the side of the sealing cylinder 19. A correction pipe 22 extending to the lower side of the jet pipe 43 is fixedly installed on the lower side of the cylinder 18, and an air transmission hole 27 connected to the correction pipe 22 is provided on the lower side of the sealing cylinder 19. A horizontal detection mechanism 23 is installed on the side of the axis of the sealing cylinder 19. When the axis of the jet pipe 43 is parallel to the horizontal plane, the ventilation hole 20 and the air guide hole 21 are dislocated with each other, and the sealing cylinder 19 blocks the ventilation hole 20. When the axis of the jet pipe 43 is inclined relative to the horizontal plane, the horizontal detection mechanism 23 drives the sealing cylinder 19 to rotate, and the ventilation hole 20 is connected to the air guide hole 21.

[0039] When the jet pipe 43 jets a large amount of air and the algae removal device moves quickly, the algae removal device tilts up, thereby changing the jet direction of the jet pipe 43, so that the axis of the jet pipe 43 is tilted relative to the horizontal plane. At this time, the horizontal detection mechanism 23 drives the sealing cylinder 19 to rotate, so that the air guide hole 21 on the sealing cylinder 19 is connected with the air exchange hole 20 on the cylinder 18, so that the high-pressure gas passing through the jet pipe 43 will partially pass through the air exchange hole 20, the air guide hole 21 and the air transfer hole 27 to reach the correction pipe 22. Since the correction pipe 22 is located on the lower side of the jet pipe 43, gas will be ejected from the lower side of the jet pipe 43, thereby providing an upward thrust for the jet pipe 43, so that the jet pipe 43 that is in a tilted state relative to the horizontal plane is subjected to an upward thrust, that is, an upward thrust is applied to the opposite side of the tilted algae removal device, thereby assisting the algae removal device to be corrected smoothly and reducing the tilting amplitude.

[0040] See also Fig.11 and Fig.12 The horizontal detection mechanism 23 includes an arc-shaped protective shell 231 fixedly installed on the jet pipe 43, a connecting rod 232 is fixedly installed on the axial side of the sealing cylinder 19, a transmission rod 233 is fixedly installed on the side of the connecting rod 232 and located in the arc-shaped protective shell 231, a counterweight block 234 is 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.

[0041] When the algae removal device is tilted, the axis of the jet pipe 43 is inclined relative to the horizontal plane. Because the counterweight block 234, under the action of gravity, drives the transfer rod 233 to always remain in a vertical downward state, so that when the jet pipe 43 is tilted relative to the horizontal plane, the transfer 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 connected with the air exchange hole 20 on the cylinder 18.

[0042] Due to the different jet speeds of the jet pipe 43, or the different resistances encountered by the algae removal device on the water surface, the tilting angle of the algae removal device when moving is also different. If the tilting angle of the algae removal device is high, and the airflow flow rate sprayed by the correction pipe 22 is low, the correction effect of the algae removal device is poor. If the tilting angle of the algae removal device is low, and the airflow flow rate sprayed by the correction pipe 22 is high, the algae removal device is over-corrected, resulting in greater shaking of the algae removal device when moving and poor movement stability.

[0043] See also Fig.10 and Fig.13 In order to solve the above technical problems, a plurality of ventilation holes 20 are provided on the side surface of the cylinder 18 along the axis direction of the cylinder 18, and a plurality of air guide holes 21 are provided on the side surface of the sealing cylinder 19 in a spiral manner. As the rotation angle of the sealing cylinder 19 relative to the cylinder 18 increases, the number of corresponding air guide holes 21 connected to the ventilation holes 20 increases.

[0044] As the tilting angle of the algae removal device gradually increases, the horizontal detection mechanism 23 drives the sealing tube 19 to rotate at an angle relative to the cylinder 18, thereby increasing the number of connections between the air guide holes 21 and the ventilation holes 20 on the sealing tube 19, and then the air flow in the jet pipe 43 enters the correction pipe 22 through the ventilation holes 20, the air guide holes 21 and the air transfer holes 27. The gas also increases, thereby increasing the upward thrust of the water on the jet pipe 43. As a result, the larger the tilting angle of the algae removal device, the greater the upward thrust it receives, thereby improving the stability of the algae removal device.

[0045] See also Fig.11 and Fig.12 , in order to reduce the backflow of water from the correction pipe 22. A sealing plate 24 is rotatably installed on the inner wall of the correction pipe 22, a stopper 25 is fixedly installed on the inner wall of the correction pipe 22 and located on the upper side of the sealing plate 24, and an elastic member 26 is fixedly installed in the correction pipe 22 for driving the sealing plate 24 to abut against the stopper 25, and the elastic member 26 is a volute spring.

[0046] When there is no gas flowing in the correction pipe 22, the sealing plate 24 abuts against the block 25 under the drive of the elastic member 26, thereby sealing the correction pipe 22 and preventing external water from flowing into the correction pipe 22; when the correction pipe 22 is ventilated, the air pressure pushes open the sealing plate 24, so that the air flow passes through the lower side of the correction pipe 22 and sprays into the water.

[0047] Because the jet pipe 43 is located in the water, water will enter the jet pipe 43 along the jet holes of the jet pipe 43. Due to the hydraulic balance, water may even exist in part of the air supply pipe 42. In untreated waters, there is a large amount of algae in the water, so the algae or impurities in the water may enter the jet pipe 43 and the air supply pipe 42 along with the water flow, which may easily cause the jet pipe 43 and the air supply pipe 42 to be blocked, or partially blocked, affecting the flow of gas, thereby affecting the movement efficiency of the algae removal device, and even causing damage to the moving mechanism 4.

[0048] See also Figure 1 , Figure 2 and Figure 5 In order to solve the above technical problems. A plug 45 for blocking the outlet is slidably arranged inside the jet pipe 43 and located at the outlet. The plug 45 is truncated cone-shaped. A moving rod 46 is fixedly installed on one side of the plug 45. A guide plate 47 is sleeved on the surface of the moving rod 46. The guide plate 47 is fixedly connected to the inner wall of the jet pipe 43. A pressure plate 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 pressure plate 48 and the guide plate 47. In the initial state, the plug 45 abuts against the edge of the outlet, and the first spring 49 is in a compressed state.

[0049] In the initial state, under the elastic force of the first spring 49, the plug 45 abuts against the edge of the outlet, thereby blocking the outlet and preventing water from flowing into the jet pipe 43. When the algae removal device needs to move, the air pump 41 starts to work and delivers high-pressure gas to the jet pipe 43 through the air delivery pipe 42. Although the outlet of the jet pipe 43 is blocked by the plug 45, as the high-pressure gas is continuously delivered to the jet pipe 43, the pressure in the jet pipe 43 increases, thereby pushing the plug 45 to move and separate from the edge of the outlet. At this time, the gas in the jet pipe 43 will be ejected through the gap between the plug 45 and the outlet, thereby realizing the movement of the algae removal device. The movement of the plug 45 will drive the moving rod 46 to move together, and the movement of the moving rod 46 will drive the pressure plate 48 to squeeze the first spring 49, thereby increasing the elastic potential energy accumulated inside the first spring 49. When the air supply pipe 42 no longer delivers gas, the pressure in the jet pipe 43 gradually decreases. Under the elastic force of the first spring 49, the plug 45 gradually approaches the edge of the outlet of the jet pipe 43 until the plug 45 abuts against the edge of the outlet of the jet pipe 43, isolating the external water from the inside of the jet pipe 43, and preventing water from flowing back into the jet pipe 43.

[0050] 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 inside the first spring 49. Too much entangled waterweed and excessive surface attachment are not conducive to recovery, and the floor space is too large and inconvenient to place.

[0051] See also Figure 5 In order to solve the above technical problems, a guide rod 410 passing through the first spring 49 is fixedly installed on one side of the pressure plate 48, and a socket 411 for the guide rod 410 to pass through is opened on the guide plate 47.

[0052] Because the guide rod 410 passes through the first spring 49 , if radial bending occurs during the compression of the first spring 49 , the first spring 49 will contact the guide rod 410 , so that the guide rod 410 limits the bending of the first spring 49 and ensures that elastic potential energy is accumulated inside the first spring 49 .

[0053] When the plug 45 is separated from the edge of the outlet and the gas is ejected outward from the gap between the plug 45 and the outlet, the gas will be dispersed and ejected from around the plug 45. As a result, after the gas comes into contact with water, the reaction force of the water is partially consumed, in order to increase the gas ejection pressure and the reaction force of the water on the algae removal device.

[0054] See also Figure 5 A gathering hood 412 is fixedly installed on one side of the jet pipe 43 away from the air supply pipe 42. The gathering hood 412 is a hollow frustum. Ventilation holes are provided on both sides of the gathering hood 412. The inner diameter of the cross section of the gathering hood 412 becomes smaller as it is away from the jet pipe 43.

[0055] When the gas is ejected through the gap between the plug block 45 and the outlet of the jet pipe 43, since the plug block 45 is in a truncated cone shape, the gas is ejected at an inclined angle relative to the axis of the plug block 45. When contacting the inner wall of the gathering hood 412, the inner diameter of the cross section of the gathering hood 412 becomes smaller as it is farther away from the jet pipe 43. Therefore, the gas ejected into the gathering hood 412 contacts the inner wall of the gathering hood 412 while moving, thereby changing the gas flow direction and moving toward the middle of the gathering hood 412, and then ejected into the water through the vents on the gathering hood 412, thereby increasing the gas ejection intensity.

[0056] See also Figure 2 and Figure 3 The driving unit 44 includes a first stepper motor 441 arranged in the protective cover 1, a gear 442 is fixedly installed on the output shaft of the first stepper motor 441, a gear ring 443 meshing with the gear 442 is fixedly installed on the side surface of the air supply pipe 42, the air supply pipe 42 is fixedly connected to the air pump 41, the air supply pipe 42 is fixedly connected to the jet pipe 43, the first stepper motor 441 is connected to the controller 9 by electrical signals, the air supply pipe 42 and the air pump 41 are both rotatably arranged with the float box 3, and the air supply pipe 42 and the air pump 41 are both rotatably arranged with the protective cover 1.

[0057] When it is necessary to adjust the moving trajectory of the algae removal device, the operator sends a signal which is received by the signal transceiver antenna 11, and the signal transceiver antenna 11 transmits the signal to the controller 9. The controller 9 controls the first stepper motor 441 to drive the gear 442 to rotate, the gear 442 drives the ring gear 443 to rotate, the ring gear 443 drives the air supply pipe 42 to rotate, and then drives the jet pipe 43 to rotate, thereby adjusting the jet direction and adjusting the moving trajectory of the algae removal device.

[0058] In order to further adjust the center of gravity of the algae removal device and improve the stability of the algae removal device when moving, the jet pipe 43 includes an outer pipe 431 and multiple inner pipes 432 (only one inner pipe 432 is drawn in the attached figure for representation), the outer pipe 431 is sleeved on the surface of the inner pipe 432, and the adjacent inner pipes 432 are sleeved on each other. A guide unit is provided between the outer pipe 431 and the inner pipe 432 and between the adjacent inner pipes 432 to guide the adjacent pipes to slide linearly (that is, a guide unit is provided between the outer pipe 431 and the inner pipe 432 with the largest inner diameter, and a guide unit is provided between two adjacent inner pipes 432), one side of the inner pipe 432 with the smallest inner diameter is fixedly connected to the air supply pipe 42, and the correction pipe 22 is fixedly installed on the outer pipe 431.

[0059] The guide unit includes a guide block and a guide groove. Between adjacent pipes, the guide block is fixedly installed on the inner wall of the pipe with a larger inner diameter, the guide groove is opened on the outer side of the pipe with a smaller inner diameter, and the guide block is slidably arranged in the guide groove.

[0060] The gas in the air pump 41 is delivered to the inner tube 432 with the smallest inner diameter through the air delivery pipe 42, thereby increasing the internal pressure of the jet pipe 43. At this time, the jet port of the jet pipe 43 is blocked by the plug 45, that is, the jet outlet of the outer tube 431 is blocked by the plug 45. Therefore, when 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 slide in a straight line under the guidance of the guide unit, thereby increasing the internal space of the jet pipe 43, until the outer tube 431 and the inner tube 432 move to the maximum displacement, that is, the jet pipe 43 When the jet pipe 43 is extended to the maximum length, the outer tube 431 and the inner tube 432 can no longer be extended, and the internal pressure of the jet pipe 43 gradually increases to push the plug 45 away, thereby realizing the jetting operation of the jet pipe 43. The extension operation of the jet pipe 43, on the one hand, increases the contact area between the bottom of the algae removal device and the water, increases the bottom range, and lowers the center of gravity of the algae removal device, so that the movement of the algae removal device is more stable. On the other hand, the jet pipe 43 is extended in length, and its internal space is increased, which will increase the buoyancy of the algae removal device, and at the same time, the algae removal device floats upward when moving, reducing the splashing water flow into the protective cover 1 during movement, which damages the equipment; When the algae removal device moves to the designated position, air is pumped out through the air pump 41. During the pumping process, the pressure inside the jet pipe 43 decreases, so that the block 45 blocks the jet port again. At this time, it is difficult for the jet pipe 43 to absorb gas from the outside, and its internal pressure will gradually decrease, so that the outer tube 431 and the inner tube 432 slide relative to each other again, and the jet pipe 43 contracts until it returns to its initial position. On the one hand, by reducing the length of the jet pipe 43, the attachment area of ​​the algae in the lake to the surface of the jet pipe 43 is reduced, thereby reducing the difficulty of cleaning. On the other hand, it is convenient to recover the algae removal device. If the bottom jet pipe 43 is too long and the range is too wide, it is inconvenient to salvage and transport it, and it occupies a large area when placed.

[0061] When the jet pipe 43 ejects gas to move the algae removal device, the jet pipe 43 continuously ejects gas in the water. Therefore, when the driving unit 44 drives the jet pipe 43 to rotate, on the one hand, the water resistance is relatively large, and the buoyancy box 3 is also floating on the water. When the jet pipe 43 rotates relative to the buoyancy box 3, the reaction force of the jet pipe 43 on the buoyancy box 3 will also cause the buoyancy box 3 to be subjected to a rotational torque, so that the buoyancy box 3 rotates on the water. Therefore, if the rotation angle of the jet pipe 43 is too large and the speed is too fast, the buoyancy box 3 will also rotate relative to the water surface, resulting in the actual rotation angle of the jet pipe 43 relative to the buoyancy box 3 being smaller than the predicted angle, which is easy to cause errors in trajectory correction. On the other hand, during the trajectory correction process, the jet pipe 43 is always jetting outward, so when correcting the moving trajectory of the algae removal device, there will be a larger arc, the correction range is too large, and the correction time is too long.

[0062] See also Figure 4-Figure 6 , in order to solve the above technical problems. The air supply pipe 42 is connected to the air jet pipe 43 through an adjusting mechanism 5, which includes a cylindrical shell 51, the axial side of the cylindrical shell 51 is fixedly connected to the axial side of the air supply pipe 42, there are at least four air jet pipes 43, and the four air jet pipes 43 are evenly distributed on the side of the cylindrical shell 51, and the cylindrical shell 51 is provided with a through hole 52 connected to the air jet pipe 43, and a sealing cover 53 is rotatably installed in the cylindrical shell 51, the sealing cover 53 is a cylinder with an opening at the upper end, and the side of the sealing cover 53 is provided with an air outlet 54, and a second stepping motor 55 is installed on the sealing cover 53 to drive the sealing cover 53 to rotate around the axial direction of the cylindrical shell 51, and when the air outlet 54 on the sealing cover 53 is connected to one of the through holes 52, the sealing cover 53 seals the other through holes 52.

[0063] When the moving track of the algae removal device needs to be corrected, if the deviation angle is too large, or if there is too much displacement and it needs to return, a signal can be sent to the signal transceiver antenna 11, and the signal transceiver antenna 11 receives the signal and transmits the electrical signal to the controller 9. The controller 9 controls the second stepper motor 55 to drive the sealing cover 53 to rotate. According to the judgment of the staff, the air outlet 54 on the sealing cover 53 is rotated to the position of the other jet pipe 43 with a smaller adjustment angle, so that the jet is sprayed through another jet pipe 43, so that there is no need to rotate the jet pipe 43 at a large angle, and the jet direction in the water can be changed, and the moving track of the algae removal device can be adjusted more quickly; A more specific working method is, for example, when the algae removal device moves too much and exceeds the target position, at this time, it is only necessary to rotate 180 degrees through the second stepper motor 55, that is, to rotate the air outlet 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 housing 51, it is not affected by the resistance in the water, and the current method consumes less energy; If there is a slight trajectory deviation of 10 to 45 degrees, the driving unit 44 can be used to adjust the angle of the jet pipe 43 that is currently jetting, which is more flexible to use and speeds up the correction rate.

[0064] When the algae removal device moves in the lake, the water flow moves, which may cause the algae removal device to float. As a result, the control of the algae removal device by other jet pipes 43 will be quickly replaced, that is, the air outlet 54 on the sealing cover 53 will be connected with other perforations 52. At this time, the connected jet pipe 43 will be extended again and spray outward. However, when the jet pipe 43 is recovered, because the air outlet 54 on the sealing cover 53 is only connected with one of the perforations 52, the originally stretched jet pipe 43 cannot be contracted and remains stretched.

[0065] 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 transfer hole 566 connected to the one-way air inlet valve 56 is opened on the side wall of the sealing cover 53. When the air outlet 54 is connected to one of the through holes 52, the three transfer holes 566 are also connected to the remaining three through holes 52, that is, one transfer hole 566 is connected to one through hole 52. When the air pump 41 inhales, the one-way air inlet valve 56 opens, so that the air pump 41 can achieve the suction effect on all the jet pipes 43, so that each jet pipe 43 can shrink.

[0066] See also Figure 4 and Figure 7The one-way air intake valve 56 includes a valve column 561 fixedly mounted on the inner wall of the sealing cover 53, a valve cover 562 is mounted on one side of the valve column 561, a positioning column 563 is fixedly mounted on the side of the valve cover 562 close to the valve column 561, a retaining ring 564 is fixedly mounted on the inner wall of the valve column 561, and a second spring 565 is fixedly mounted between the retaining 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.

[0067] When the sealing cover 53 is in an inhalation negative pressure state, the valve cover 562 is in a negative pressure state, driving the positioning column 563 to overcome the elastic force of the second spring 565 and move in a direction away from the valve column 561, thereby opening the seal on the valve column 561, so that the gas in the jet pipe 43 is absorbed through the through hole 52, the transfer hole 566 and the valve column 561, completing the contraction of the jet pipe 43.

[0068] See also Figure 2 and Figure 3 A through hole 6 is provided in the buoyancy box 3 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 on the inner wall of the through hole 6. The ball bearings 7 can reduce the friction between the air supply pipe 42 and the through hole 6 on the one hand, and provide support for the air supply pipe 42 on the other hand.

[0069] See also Figure 2 and Figure 8 A positioning mechanism 8 is installed on the protective cover 1, and the positioning mechanism 8 includes 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 connected to the controller 9 by electrical signals.

[0070] When the algae removal device moves 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 the electrical signal to the controller 9. The controller 9 controls the winding machine 81 to release the pull rope 82, so that the positioning anchor 83 sinks to the bottom of the water, thereby positioning the algae removal device. When the algae removal device needs to be moved, the pull rope 82 is wound up by the winding machine, the positioning anchor 83 is pulled up, and then the algae removal device is moved.

[0071] See also Figure 1 In order to keep the algae removal equipment sufficient in power and self-sufficient, a solar panel 17 is installed on the protective cover 1, and a battery is installed in the protective cover 1. The battery is connected to the solar panel 17 with an electric wire, and the battery provides power for the controller 9.

Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
