Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to an algae monitoring system. Background Art

[0002] The recent algal blooms in Shanghai and the eastern Yangtze River Delta further highlight the impact of eutrophication on the aquatic ecosystem. Algal blooms are caused by a variety of factors, primarily the high levels of nitrogen and phosphorus in domestic and industrial wastewater. Algal cells rapidly multiply in the adapted aquatic environment, accumulating on the water surface and forming a layer of foul-smelling floating debris. Currently, a number of automated salvaging devices have been developed to replace manual salvaging methods, improving the efficiency of algal bloom treatment. However, these automated salvaging devices are not highly intelligent and cannot dynamically monitor algae from initial formation to bloom formation. Even when these devices detect algae, they only passively salvage the algae and fail to proactively mitigate or prevent bloom formation at the source, resulting in sporadic algal blooms. Furthermore, the salvage of algae is done directly from the water surface to the salvage equipment or outside, without considering that the algae also contain a large amount of absorbed nitrogen and phosphorus, which can be buried in the bottom mud to form waste for fertilizing crops. In a water body longitudinal mixing device disclosed in the patent document with application number CN202210847795.4, a plurality of vertical mixing devices 3 are set at the lower end of the frame 2. The vertical mixing device 3 includes a plurality of fan blades 38 driven by a conveyor belt 310 for cyclic lifting. Through the cyclic lifting of the fan blades 38, the algae are driven into different layers in the water body, thereby achieving the purpose of killing the algae. However, the depth reached by the vertical mixing device 3 does not involve the bottom of the river. It does not take into account the ability to directly deliver the algae from the surface of the water body to the bottom of the river for burial. After it is buried and fermented in the river bottom mud, it is recovered together with the bottom mud for use in agricultural planting. In this way, the trouble of collecting algae can be avoided and the nitrogen and phosphorus absorbed by the algae can be recycled.

[0003] It can be seen from this that in the prior art, although there has been an automatic algae salvage device to replace manual salvage for the problem of algae bloom in water bodies, and there has also been a method of transporting algae to different levels of the water body to kill the algae, there has not been a method that can monitor the algae in the water body and take measures before the water body blooms, by burying the algae in the mud at the bottom of the water body so that the algae can be recycled when the mud is recycled. In order to cooperate with the burial of algae, a corresponding device is set up to intercept the algae in a certain water area, and a very small algae monitoring system is used to treat the algae in a large area of ​​water. To this end, the present invention provides an algae monitoring system for treating water body algae bloom, fermenting the algae in the bottom mud, and cooperating with a fence structure to carry out efficient and rapid algae treatment in the water body, which can avoid algae bloom or perform efficient treatment when algae bloom occurs.

[0014] The beneficial effects of the present invention are:

[0015] 1) The algae monitoring system of the present invention can monitor water bodies in real time and has a water bloom treatment mode and a normal operating mode. In the water bloom treatment mode, algae on the surface of the water body can be transported to the bottom of the water body through a number of hemispherical hoppers provided on the algae collection rod group, and the algae can be buried in the bottom mud at the bottom of the water body. This configuration not only takes into account the trouble of traditional algae salvage and subsequent processing, but also can convert the nitrogen and phosphorus elements within the algae into waste. By subsequently directly digging out the bottom mud, it can be used as fertilizer for local crop production, reducing the use of chemical fertilizers, thereby suppressing the occurrence of water blooms to a certain extent and reducing the capital investment in crop production. At the same time, aquatic plants are also planted within the main frame of the monitoring system. In the normal operating mode, the hemispherical hoppers can transport the bottom mud to the surface of the water body for the aquatic plants to absorb nutrients. In this way, the system can not only treat the algae produced by the water bloom, but also use the algae buried in the bottom mud as fertilizer for the aquatic plants to absorb, further reducing the nitrogen and phosphorus elements in the water body and reducing the application of fertilizers.

[0016] 2) Furthermore, in order to improve the burying efficiency of algae on the surface of the water body when algae bloom occurs, the present invention further provides a gathering net group outside the main frame. The gathering net group performs a contraction action through a net action component. The gathering net group is composed of a number of arc-shaped contraction nets that can slide with each other. The focusing net group can perform a synchronous contraction action after the hemispherical hopper of the algae collection rod group collects the algae on the surface of the water body, so that the algae can be gathered together for a continuous cycle of burying action of the hemispherical hopper, which can further accelerate the efficiency of algae bloom treatment. At the same time, the hemispherical hopper is a structure formed by an elastic membrane and a hopper body. A liquid-filled space is formed in the elastic membrane and the hopper body. Oxygen can be introduced into the liquid-filled space. When the hopper body is in an idle state, the liquid-filled space can be filled, and oxygen can be ejected from the liquid-filled space, thereby oxygenating the water body. At the same time, the spherical structure formed by the elastic membrane and the hopper body can also rotate, so that oxygen can be more fully injected into the water body, further solving the problem of hypoxia.

[0017] 3) Furthermore, in order to enable the algae to be smoothly buried in the bottom mud in the algae bloom treatment mode without the bottom mud being brought out, a bottom mud retaining plate is provided at the lower end of the algae collecting rod group, and a circular blocking component 1 is provided on the bottom mud retaining plate. The circular blocking component 1 includes a through circular groove 1 with an opening and closing door structure, a through long strip groove and a through circular groove 2. The circular blocking component 1 cooperates with the elastic membrane of the hemispherical hopper and the shape of the hopper body, and can bury the algae in the bottom mud when the hemispherical hopper enters the circular blocking component 1. After being buried in the bottom mud, the elastic membrane and the hopper body expand to form a spherical structure. In this way, the algae can be unloaded, and at the same time, the bottom mud will not be brought out when the hemispherical hopper slides out of the bottom mud retaining plate. The mud is brought out, and in the normal operating mode, the upper end of the algae collecting rod group is slidably connected to a supplementary mud holding plate, which is arranged on the lower end of the outer ring frame and / or the inner ring frame through a telescopic cylinder. The supplementary mud holding plate also includes a circular blocking component 2, which includes a through circular groove 1, a through groove 1, a through circular groove 2, a through groove 2 and a return circular groove 2 with an opening and closing door structure. The circular blocking component 2 cooperates with the elastic membrane of the hemispherical hopper and the shape of the hopper body, and can bring the bottom mud into the hemispherical hopper when it enters the circular blocking component 2, and then the elastic membrane and the hopper body expand to form a spherical structure. In this way, the bottom mud can be unloaded, and at the same time, the bottom mud will not be brought out when the hemispherical hopper slides out of the supplementary mud holding plate;

[0018] 4) Furthermore, in order to adapt to main rods of different lengths, the transmission belt includes a belt insertion end and a belt receiving end, and the belt insertion end can be inserted into the inner side of the belt receiving end, and the belt insertion end and the belt receiving end can be driven to slide by a telescopic driving member, thereby realizing that the length of the transmission belt is adapted to the length of the main rod. Furthermore, in order to make the distance between the hemispherical hoppers still adaptively modified after the length of the transmission belt is changed, the first support rod is fixed, and the other support rods are all slidable structures, and the two support rods are connected by a tensioning fork. Through such an arrangement, after the length of the transmission belt is changed, the linkage action of the tensioning fork can realize that the distance between the support rods can be adapted to the length of the transmission belt, and the distance between the support rods is still equal. In this way, the amount of algae processed by the hemispherical hopper per unit time can be constant, which is convenient for calculating the distance that the synchronously moving aggregation net group needs to move, thereby realizing rapid processing of algae during water bloom.

[0019] 5) Finally, in order to be able to collect algae in all directions, the algae collecting rod group can be slidably set on the connecting rod connected between the inner ring frame and the outer ring frame, and sliding sealing grooves are provided on the bottom mud retaining plate and the supplementary mud retaining plate that cooperate with the algae collecting rod group, and the circular sealing component 1 and the circular sealing component 2 are both set in the sliding sealing grooves, so that it can adapt to the free sliding of the algae collecting rod group. At the same time, several algae collecting rods in the algae collecting rod group include rotating ends, so that the collection direction of the hemispherical hopper can be freely changed. At the same time, the support rod is also a retractable structure, which can further increase the working range of the hemispherical hopper. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is further described below with reference to the embodiments, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention fall within the scope of protection of the present invention.

[0037] An algae monitoring system, such as Figure 1-12 As shown, it includes a main frame 1, a gathering net group 2 and an algae collecting rod group 3. The gathering net group 2 is arranged on the periphery of the main frame 1 through a net action component 8. The algae collecting rod group 3 is arranged on the lower end of the main frame 1 through a collection rod group action component 9. The algae collecting rod group 3 is composed of a plurality of algae collecting rods. Figure 4-6 As shown, it includes a main rod 10 and a rotating end 11. The main rod 10 is provided with an upper horizontal through groove 12 at one end close to the rotating end 11, and a lower horizontal through groove 14 at the end away from the rotating end 11. Guide grooves 13 are provided at both ends of the main rod 10. An upper driving wheel 15 and a lower driving wheel 16 are respectively rotatably provided at the upper horizontal through groove 12 and the lower horizontal through groove 14. A transmission belt 44 is wound around the upper driving wheel 15 and the lower driving wheel 16, and a number of hemispherical hoppers 18 are provided on the transmission belt 44. When the hemispherical hopper 18 is driven by the transmission belt 44 to circulate, when the hemispherical hopper 18 moves to the uppermost end of the main rod 10, the algae on the surface of the water body can be collected into the hemispherical hopper 18. When the hemispherical hopper 18 moves to the lowermost end of the main rod 10, the algae in the hemispherical hopper 18 can be buried in the bottom mud at the bottom of the water body.

[0038] like Figure 7-8 As shown, it also includes a bottom mud holding plate 25, which is movably arranged at the lower end of the algae collecting rod group 3, and a plurality of circular blocking components 29 are also provided on the bottom mud holding plate 25. The circular blocking component 29 includes a guide ring plate 30, a rotating ring plate 31 and a blocking circular plate 32. The guide ring plate 30 is clamped on the inner periphery of the bottom mud holding plate 25, the inner periphery of the rotating ring plate 31 is fixedly connected to the blocking circular plate 32, and the outer periphery of the rotating ring plate 31 is clamped on the bottom mud holding plate 25. The inner periphery of the guide ring plate 30 is rotatable relative to the guide ring plate 30, and a passing long groove 35 is provided in the middle of the blocking circular plate 32. A passing circular groove 1 36 and a return circular groove 2 37 are provided at the longitudinal position of the long groove 35 at both ends of the passing long groove 35, and a positioning groove 1 33 and a positioning groove 2 34 are provided at the transverse position of the long groove 35 at both ends of the long groove 35. The positioning groove 1 33 and the positioning groove 2 34 are used for positioning with the lower end of the main rod 10.

[0039] like Figure 9As shown, the hemispherical hopper 18 includes a hopper body 38, a mounting block 39 and an elastic membrane 40. The mounting block is fixedly arranged on one side of the hopper body 38, and the elastic membrane 40 is fixedly arranged on the upper end of the hopper body 38. The head body 38 and the elastic membrane 40 are both hemispherical, and a liquid-filled space 41 is formed between the hopper body 38 and the elastic membrane 40. Figure 9 As shown in (a), at this time, the liquid-filled space 41 is not filled with fluid, and the elastic membrane 40 is attached to the inner side of the hopper body 38. At this time, the hemispherical hopper 18 can be loaded with algae, as shown in FIG. Figure 9 As shown in (b), at this time, the liquid-filled space 41 is filled with fluid, the elastic membrane 40 expands, and the elastic membrane 40 and the hopper body 38 form a complete sphere, and the algae are discharged from the hemispherical hopper 18. When the hemispherical hopper 18 moves to the surface of the water body, the liquid-filled space 41 of the hemispherical hopper 18 is not filled with fluid, and the algae on the surface of the water body enter the hemispherical hopper 18. As the hemispherical hopper 18 moves downward to the bottom of the water body, the algae in the hemispherical hopper 18 also move to the bottom of the water body. After further movement, the hemispherical hopper 18 passes through the circular groove 36 and enters the lower end of the bottom mud retaining plate 25. At this time, the algae are buried in the bottom mud, so that the liquid-filled space 41 is filled with fluid, thereby forming a sphere. The hemispherical hopper 18 continues to move. The hemispherical hopper 18 passes through the return circular groove 37 and is located above the bottom mud retaining plate 25. Through the expansion, contraction, collision and lifting action of the hemispherical hopper 18, the algae on the surface of the water body can be buried in the bottom mud, thereby solving the problem of a large amount of floating algae on the surface of the water body when algal bloom occurs. At the same time, the algae can be directly buried in the bottom mud. After the algae are buried for a period of time, the algae can also be turned into waste. Finally, the bottom mud can be dug out to obtain fertilizer rich in nitrogen and phosphorus elements.

[0040] In order to enable the algae collecting rod group 3 to adapt to water bodies of different depths, the main rod 10 of the algae collecting rod is made into a telescopic rod structure. For example, the main rod 10 can be set to be connected with several rod ends, and then the end ends are connected through a telescopic oil cylinder. In this way, the overall length of the main rod 10 can be extended or shortened by the telescopic action of the telescopic oil cylinder. In order to adapt to the main rod 10 whose overall length can be extended or shortened, the transmission belt 44 is also a ring-shaped structure that can be changed or shortened. The specific structure of the transmission belt 44 is as follows: Figure 10-12 As shown, the two ends of the transmission belt 44 are respectively a belt accommodating end 45 and a belt insertion end 46. The belt accommodating end 45 and the belt insertion end 46 are connected by the belt body end. The belt insertion end 46 is inserted into the belt accommodating end 45 and driven by the telescopic driving member 47 to slide along the belt accommodating end 45.

[0041] In order to make the spacing between the several support rods 17 provided on the transmission belt 44 also adjustable accordingly with the change of the length of the transmission belt 44, a support rod 17 is fixedly provided at the end of the belt accommodating end 45, and it is defined as the first support rod 50. On the transmission belt 44, from the belt accommodating end 45 along the direction of the belt insertion end 46, the second support rod 61, the third support rod... the Nth support rod... the end support rod 52 are slidably provided in sequence (specifically N is a natural number, and the number can be flexibly selected according to the length of the transmission belt 44). The sliding structures of the second support rod 61, the third support rod... the Nth support rod... the end support rod 52 are the same. The sliding structure of the second support rod 61 is taken as an example for explanation. Figure 11-12 As shown, the belt accommodating end 45 includes a accommodating body 53, the upper end of the accommodating body 53 is provided with a guide groove 48, the inner side of the accommodating body 53 is formed with an accommodating cavity 54, the telescopic driving member 47 is fixedly arranged in the accommodating cavity 54, the lower end of the second support rod 61 is provided with a clamping end 55, the clamping end 55 is clamped into the guide groove 48, and a guide groove 2 49 is provided on the upper side of the belt insertion end 46, and the end support rod 52 is clamped into the guide groove through the clamping end 55 In the second 49, a tensioning fork 51 is provided between two adjacent support rods 17. The tensioning fork 51 includes an upper fork rod 59 and a lower fork rod 60. A rotating shaft 58 is fixedly provided at the lower end of the second support rod 61. The middle parts of the upper fork rod 59 and the lower fork rod 60 pass through the rotating shaft 58 in sequence. The upper fork rod 59 and the lower fork rod 60 are hinged to the rotating shaft 58. The two ends of the upper fork rod 59 are respectively hinged to the adjacent upper fork rod 59, and the two ends of the lower fork rod 60 are respectively hinged to the adjacent lower fork rod 60.

[0042] Taking into account that when algal bloom breaks out, the oxygen content in the water body, especially in the lower part of the water body, drops sharply, and the water body needs to be oxygenated, so that a plurality of controllable opening and closing holes 42 are provided on the elastic membrane 40, and a plurality of controllable opening and closing holes 43 are provided in the hopper body 38. The fluid introduced into the liquid-filled space 41 is oxygen. After the hemispherical hopper 18 leaves the bottom mud retaining plate 25, the controllable opening and closing holes 42 and the controllable opening and closing holes 43 are in an open state. Oxygen is discharged through the plurality of controllable opening and closing holes 42 and the plurality of controllable opening and closing holes 43 and introduced into the water body to alleviate the situation where the oxygen content in the water body drops sharply.

[0043] The gathering net group 2 includes several arc-shaped contraction nets 7, and any two adjacent arc-shaped contraction nets 7 can slide relative to each other. There are several net action components 8, and the number is the same as the number of the arc-shaped contraction nets 7. Each net action component 8 includes a mounting seat 19 fixedly set on the outer ring frame 5, a mounting seat 2 20 fixedly set on the inner ring frame 4, and a telescopic rod group 67 set between the mounting seat 19 and the mounting seat 2 20. The end of the telescopic rod group 67 is connected to an arc-shaped contraction net 7. The telescopic rod group 67 includes several telescopic rods that are socketed with each other. The telescopic rods that are socketed with each other are driven by a motor to rotate and extend the threaded rod or the hydraulic cylinder to extend and extend the telescopic rod group 67. The arc-shaped contraction net 7 is moved away from or close to the outer ring frame 5 by the action of the motor or the hydraulic cylinder. In this way, the contraction of the focusing net group 2 composed of the arc-shaped contraction net 7 can be achieved.

[0044] There are several collecting rod group action components 9, the number of which is the same as the number of the algae collecting rods. The collecting rod group action components 9 all include a mounting seat three 21 fixedly set at the lower end of the inner ring frame 4, a mounting seat four 22 fixedly set at the lower end of the outer ring frame 5, and a rotating screw 23 set between the mounting seat three 21 and the mounting seat four 22. The sliding mounting seat 24 is slidably set on the rotating screw 23. A nut engaged with the rotating screw 23 is set in the sliding mounting seat 24. The rotation of the rotating screw 23 drives the sliding mounting seat 24 to slide along the connecting rod 6, so that the position of the algae collecting rod group 3 can be adjusted.

[0045] In order to make the bottom mud retaining plate 25 adapt to the algae collecting rod group 3 that can slide relative to the connecting rod 6, a plurality of sliding sealing grooves 26 are provided on the bottom mud retaining plate 25, and the number of the sliding sealing grooves 26 is the same as the number of the algae collecting rods, and the axis of the sliding sealing groove 26 is parallel to the axis of the connecting rod 6.

[0046] In order to ensure that the bottom mud will not rise due to the stirring of the hemispherical hopper 18, an elastic sealing film 27 is further provided in the sliding sealing groove 26. The elastic sealing film 27 is connected between the circular sealing component 1 29 and the bottom mud retaining plate 25, and a guide side plate 1 28 is further provided on the side of the elastic sealing film 27. An opening and closing door (not shown) is provided on the circular groove 1 36, the long groove 35 and the return circular groove 2 37. The opening and closing door is a left and right door panel that can rotate around the hinge axis. A reset spring is also provided on the hinge axis so that the door panel is closed through the circular groove 1 in the initial state. 36. After the hemispherical hopper 18 passes through the long groove 35 and the return circular groove 2 37, it pushes the opening and closing door at the circular groove 36 to open inward. After it fully enters, the opening and closing door is closed again under the action of the return spring. After the support rod 17 passes through the long groove 35, it pushes the opening and closing door at the long groove 35 to open inward. After it fully enters, the opening and closing door is closed again under the action of the return spring. After the hemispherical hopper 18 passes through the return circular groove 2, it pushes the opening and closing door at the return circular groove 2 to open outward. After it completely slides out, the opening and closing door is closed again under the action of the return spring.

[0047] The bottom end of the main rod 10 can be extended into the positioning groove 1 33 and the positioning groove 2 34. By setting a magnet in the main rod 10 and setting another magnet in the positioning groove 1 33 and the positioning groove 2 34, the movable connection between the bottom mud retaining plate 25 and the algae collection rod group 3 is achieved through the mutual attraction of the two magnets.

[0048] The specific structure of the telescopic drive member 47 takes into account that the transmission belt 44 needs to be bent. In order to adapt to the transmission belt 44, the telescopic drive member 47 is a rotary motor. The rotary motor is arranged in the accommodating body 53. The gear of the rotary motor is exposed to the accommodating cavity 54, so that the lower end of the belt insertion end 46 is provided with a plurality of teeth to form a rack structure. The gear of the rotary motor rotates to realize the sliding of the belt insertion end 46 relative to the belt accommodating end 45, thereby realizing the change of the length of the entire transmission belt 44.

[0049] Preferably, the rotating end head 11 is fixedly arranged on the sliding mounting seat 24, and the rotating end head 11 can make the main rod 10 rotate relative to the sliding mounting seat 24. Such a setting can make the working range of the hemispherical hopper 18 larger and can cover a larger range of algae. The specific rotation can be achieved by, for example, a motor driving a gear. The specific rotation method is common knowledge in this field and is not the focus of this application, so it will not be repeated.

[0050] Preferably, a mounting block 39 is provided at the end of the support rod 17. The mounting block 39 also enables the hemispherical hopper 18 to rotate relative to the support rod 17. In this way, the direction of the hemispherical hopper 18 can be adjusted arbitrarily. When the liquid-filled space 41 in the hemispherical hopper 18 is full, the oxygen in the liquid-filled space can be fully exposed to more water when it is ejected, thereby achieving a better oxygenation effect in the water. Preferably, in order to increase the flexibility and movement space of the hemispherical hopper 18, the support rod 17 can be a telescopic rod structure.

[0051] Through the applicant's research on algal blooms in the waters of Shanghai and the eastern part of the Yangtze River Delta, it was found that before the algal bloom breaks out, the concentration of carbon dioxide in the water body will change greatly. After the algal bloom breaks out, the algae on the surface of the water body cover the water body, and the aquatic plants in the lower part of the water body cannot carry out photosynthesis well, which will eventually cause the oxygen in the water body to decrease and the carbon dioxide concentration to increase. Therefore, the algal bloom can be monitored by measuring the carbon dioxide concentration. For this purpose, a number of carbon dioxide concentration detection sensors are also provided on the algae collection rod group 3 to detect the concentration of carbon dioxide in the water body.

[0052] In order to ensure that the main frame can float stably on the water surface, an outer floating ring 56 is fixedly provided on the outer side of the outer ring frame 5 , and an inner floating ring 57 is provided on the inner side of the inner ring frame 4 .

[0053] Preferably, in order to better absorb nitrogen and phosphorus elements in the water body, a floating bed is provided in the space formed by the inner ring frame 4, the outer ring frame 5 and several connecting rods 6. The floating bed can be made using a foam box, etc., and then soil is placed on the floating bed to plant aquatic plants. Several holes are provided in the foam box for the roots of aquatic plants to extend out.

[0054] Furthermore, in order to facilitate the hemispherical bucket 18 to transport the bottom mud at the bottom of the water body to the upper part of the water body for use by aquatic plants, a supplementary mud retaining plate 62 that can be raised and lowered relative to the main frame 1 is fixedly provided at the bottom of the main frame 1, and the supplementary mud retaining plate 62 is fixedly provided at the lower end of the main frame 1 by a telescopic oil cylinder.

The through hole 64 is adapted to the size of the main rod 10.

[0056] A plurality of sliding sealing grooves 26 are provided on the supplementary mud retaining plate 62 , and the number of the sliding sealing grooves 26 is the same as the number of the algae collecting rods. The axis of the sliding sealing groove 26 is parallel to the axis of the connecting rod 6 .

[0057] An elastic sealing film 27 is also provided in the sliding sealing groove 26, and the elastic sealing film 27 is connected between the circular sealing component 2 63 and the replenishing mud retaining plate 62, and a guide side plate 1 28 is also provided on the side of the elastic sealing film 27. An opening and closing door (not shown) is provided on the circular groove 1 36, the through groove 1 65, the through groove 2 66 and the return circular groove 2 37. The opening and closing door is two left and right door panels that can rotate around the hinge axis. A reset spring is also provided on the hinge axis, so that the door panel is closed through the circular groove 1 36, the through groove 1 65, the through groove 2 66 and the return circular groove 2 37 in the initial state. The specific opening and closing door action process is similar to the opening and closing door action mode on the bottom mud retaining plate 25, and will not be repeated here.

[0058] Furthermore, in order to retain the soil in the supplementary mud retaining plate 62 , a blocking plate may be provided on the outer periphery of the supplementary mud retaining plate 62 to prevent soil loss.

[0059] Furthermore, in order to be able to sense whether algal bloom occurs in the water body, a camera can be set on the main frame 1. The pictures taken by the camera are compared with the pictures of algal bloom preset in the memory to determine whether algal bloom occurs. At the same time, the values ​​detected by the carbon dioxide sensor can also be combined to monitor in real time whether algal bloom occurs in the water body.

[0060] Furthermore, the oxygen can be charged by providing an oxygen inlet at the hopper body 38 and inputting the oxygen into the oxygen inlet through an oxygen pipe. The specific oxygen input structure is common knowledge in the field and is not the focus of this application, so it will not be described in detail.

[0061] Furthermore, the present application also includes a power source, such as a solar cell or a battery, and also includes a main control unit for controlling the actions of all motors or hydraulic cylinders or telescopic cylinders. It also includes a communication unit for sending instructions from the main control unit to each action unit. At the same time, a drive motor can be set at the power input end of the rotating screw, upper drive wheel, lower drive wheel, and rotating end.

[0062] Furthermore, a monitoring method of an algae monitoring system is also included:

[0063] (1) Initialization settings of the monitoring system:

[0064] 1.1 The outer and inner floating rings 56 and 57 are filled with gas, and the main frame 1 is suspended on the surface of the water. Through the action of the net action assembly 8, the gathering net group 2 is in the maximum extension state, and the arc-shaped contraction nets 7 form a maximum encirclement circle, or the arc-shaped contraction nets 7 are separated, so that algae on the surface of the water can enter the main frame 1; aquatic plants are planted in the main frame 1;

[0065] 1.2 Each algae collecting rod of the algae collecting rod set 3 is in an extended state, so that the lower end of the main rod 10 contacts the bottom mud of the water;

[0066] (2) Monitoring system action mode selection:

[0067] Determine whether algal bloom has occurred based on the detection results of the camera and the carbon dioxide sensor. When the carbon dioxide sensor detects a normal carbon dioxide concentration value and the color of the water surface photographed by the camera is normal, it is determined that the water body is in a normal state, and the algae monitoring system is in a normal operating mode. When the carbon dioxide sensor detects an abnormal carbon dioxide concentration and the color of the water surface photographed by the camera appears green or black, it is determined that algal bloom has occurred in the water body, and the algae monitoring system is in an algal bloom treatment mode.

[0068] (3) Monitoring system algal bloom treatment mode:

[0069] 1.1 Algae collection rod group action:

[0070] The upper driving wheel 15 and / or the lower driving wheel 16 of each algae collecting rod of the algae collecting rod group 3 rotates, driving the transmission belt 44 to rotate, thereby causing the hemispherical hopper 18 to start moving in the vertical direction of the water body. At this time, the hemispherical hopper 18 with the opening facing the bottom of the water body moves downward, and the hemispherical hopper with the opening facing the surface of the water body moves upward. In the process of the uppermost hemispherical hopper 18 changing from opening upward to opening downward, the algae enriched on the surface of the water body are collected into the hemispherical hopper 18, and then as the hemispherical hopper 18 moves, it finally enters the bottom mud of the water body. Then, the hemispherical hopper 18 is filled with fluid (preferably oxygen), so that the hemispherical hopper becomes Spherical, so that the algae can be buried in the bottom mud without taking out the bottom mud and algae. At the same time, after the spherical hemispherical hopper 18 enters the water body again, the fluid continues to be introduced, so that the controllable opening and closing hole 1 42 and the controllable opening and closing hole 2 43 are in an open state, so that oxygen can be introduced into the water body through the hemispherical hopper 18 to alleviate the oxygen deficiency of the water body when the algal bloom occurs; after the spherical hemispherical hopper 18 moves above the water surface, the fluid in the hemispherical hopper 8 is controlled to be sucked out, and the hemispherical hopper 8 forms a hemispherical shape again. When the hemispherical hopper 8 turns downward, the algae on the surface of the water body are filled with the hemispherical hopper 8, and thus, another cycle is carried out;

[0071] 1.2 Synchronous shrinking of aggregation network groups:

[0072] After the hemispherical hopper 8 in the algae collecting rod assembly 3 continuously buries the algae on the surface of the water body into the bottom mud, the net action assembly 8 is activated to tighten the arc-shaped contraction nets 7. In this way, the arc-shaped contraction nets 7 can gather the algae in the main frame 1 together again, so that the hemispherical hopper 8 can continuously collect algae.

[0073] Through the action of the above-mentioned algae monitoring system, the algae bloom can be buried, and at the same time, oxygen can be introduced into the water body when the algae bloom occurs, which can alleviate the oxygen deficiency during the algae bloom.

[0074] (IV) Normal operating mode of the monitoring system:

[0075] Adjust the vertical position of the mud replenishing holding plate 62 relative to the telescopic rod group 3, and rotate the upper drive wheel 15 and / or the lower drive wheel 16 of each algae collecting rod of the algae collecting rod group 3, driving the transmission belt 44 to rotate, thereby causing the hemispherical hopper 18 to start moving along the vertical direction of the water body. At this time, the hemispherical hopper 18 with the opening facing the bottom of the water body moves downward, and the hemispherical hopper with the opening facing the surface of the water body moves upward. In the process of the hemispherical hopper 18 at the lower end changing from opening downward to opening upward, the bottom mud at the bottom of the water body is scooped into the hemispherical hopper 18, and then as the hemispherical hopper 18 moves, it finally extends into the upper end of the mud replenishing holding plate 62, and leaves the bottom mud from the bottom of the water body on the mud replenishing holding plate 62 for the growth of aquatic plants, and when it is flipped to the During the downward movement, the hemispherical hopper 18 is filled with fluid (preferably oxygen), so that the hemispherical hopper becomes spherical. In this way, the bottom mud can be retained on the replenishing mud retaining plate without taking out the bottom mud. At the same time, after the spherical hemispherical hopper 18 enters the water body again, the fluid continues to be introduced so that the controllable opening and closing hole 1 42 and the controllable opening and closing hole 2 43 are in an open state. In this way, oxygen can be introduced into the water body through the hemispherical hopper 18, which can meet the oxygen deficiency condition of the water body and prevent the occurrence of algal bloom. After the spherical hemispherical hopper 18 moves under the bottom mud, the fluid in the hemispherical hopper 8 is controlled to be sucked out, and the hemispherical hopper 8 forms a hemispherical shape again. When the hemispherical hopper 8 flips upward, the bottom mud is filled up with the hemispherical head 8 again, and thus, another cycle is performed.

[0076] Furthermore, the step of (1) initializing the monitoring system also includes:

[0077] 1.3 The bottom mud retaining plate 25 is set at the lower end of the algae collecting rod group 3 by magnetic attraction.

[0078] Furthermore, in step 1.2 of synchronously contracting the gathering net group in (III) the monitoring system's water bloom processing mode, the specific contraction distance of the telescopic rod group 67 that drives the arc-shaped contraction net 7 to move is set so that the reduction in the area of ​​the circle enclosed by the arc-shaped contraction net 7 is equal to the area of ​​algae on the water surface absorbed by the hemispherical hopper 8 of the algae collection rod group 3, thereby enabling faster collection of algae when water blooms occur:

[0079] Furthermore, when all algae collecting rods of the 1.2 algae collecting rod group 3 in the initialization setting of the (1) monitoring system are in an extended state, the telescopic drive member of the transmission belt 44 is actuated, driving the belt insertion end 46 to slide out along the belt accommodating end 45, thereby lengthening the transmission belt 44. At the same time, the distance between the end support rod and the first support rod will increase, causing the tensioning fork 51 to be in an extended state, thereby adjusting the distance between the two support rods to increase simultaneously and synchronously, so that the distance between the hemispherical hoppers 18 changes with the length of the transmission belt 44.

[0080] Preferably, considering that the transmission belt 44 is in a cyclic action state, the upper fork rod 59 and the lower fork rod 60 are both made of a deformable material with a certain flexibility, such as PVC, plastic, etc.

[0081] Preferably, in order to facilitate the hemispherical hopper 18 to pass through the upper horizontal through slot 12 , the width of the upper horizontal through slot 12 can be set to be greater than or equal to the diameter of the hopper body 38 .

[0082] Preferably, the opening and closing of the controllable opening and closing hole 1 42 and the controllable opening and closing hole 2 43 can be achieved by setting an electromagnetic opening and closing valve with electromagnetic control in the hole. Specifically, it is sufficient to achieve the controllable opening and closing of the hole. This is not the focus of this application, so it will not be elaborated here.

[0083] Preferably, the above-mentioned normal operation mode of the monitoring system and the water bloom treatment mode of the monitoring system can also be selected by manual input, and the mode selection can also be performed by remote input, so that algae in the water body can still be treated after a camera or carbon dioxide sensor fails.

Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
