Description

Technical Field

[0001] The present invention belongs to the technical field of algae prevention and control, and in particular relates to a floating photovoltaic algae control and oxygenation system and an application method thereof. Background Art

[0002] As prokaryotes, algae can photosynthesize and use light energy to convert carbon dioxide and water into organic matter and oxygen. Light is the main energy source for algae to photosynthesize. Light intensity directly affects the photosynthesis rate of algae. When there is sufficient light, the photosynthesis efficiency of algae increases, thereby accelerating its growth and reproduction. However, the large-scale reproduction of algae will form "water blooms", covering the water surface, hindering the gas exchange between the water body and the air, resulting in a decrease in dissolved oxygen in the water and affecting the water quality. Excessive reproduction of algae will squeeze the living space of aquatic plants and destroy the balance of the aquatic ecosystem.

[0003] Therefore, the existing technology reduces the light intensity on the water surface through sunshade nets, water grass planting, etc., and appropriately shortens the light time, which can also reduce the photosynthesis time of algae, thereby reducing its growth rate. However, it does not eliminate the possibility of algae generation from the root, that is, the control effect is poor. Summary of the invention

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Example 1 This embodiment provides a floating photovoltaic algae control and oxygenation system to solve the problem that a large number of algae will form "water blooms" and cover the water surface, hindering the gas exchange between the water body and the air, resulting in a decrease in dissolved oxygen in the water and affecting the water quality.

[0031] like Figure 1 As shown, the floating photovoltaic algae control and oxygenation system includes: a floating frame with a predetermined area. It should be noted that the algae outbreak area and region of rivers and lakes are generally local, so the area of ​​the floating frame in this embodiment is determined according to the algae area. At the same time, in order to facilitate independent operation and river and lake management in the later stage, the floating frame of this embodiment is assembled, that is, it includes at least one group of floating frames 1. In other words, the floating frame is connected by floating frames 1 according to a predetermined layout, such as Figure 1 Matrix connection in.

[0032] Combination Figure 2 , each group of floating frames 1 is equipped with a transmission component 2, and the transmission component 2 is transmission-connected to a photovoltaic component 3, and the photovoltaic component 3 is configured to install a plurality of photovoltaic panels, and realizes the dynamic laying of the photovoltaic panels under the coordinated action of the transmission component 2; the dynamic laying is the mutual switching between horizontal laying and inclined laying. When the photovoltaic panels are laid horizontally, the light is completely blocked, which hinders the photosynthesis of algae and inhibits the growth, thereby effectively controlling algae. When the photovoltaic panels are laid at an angle, the required operating space is provided for fixed-point sampling of the water body and maintenance of the photovoltaic panels. The floating board of this embodiment needs to have high durability and be able to resist adverse factors such as water flow impact, ultraviolet radiation, and chemical corrosion. In terms of material selection, corrosion-resistant and anti-aging polymer materials such as polyethylene and polypropylene can be used.

[0033] In order to fully utilize the light energy and protect the water environment, the present embodiment further includes: an aeration device arranged at a designated position of the river or lake, and the designated position is preferably located below or near the floating frame. The aeration device is connected to the photovoltaic module 3 through an electrical connection and a conversion member, so that the photovoltaic module 3 serves as a power source for the aeration device, driving the aeration device to oxygenate the oxygen-deficient bottom water body.

[0034] It is worth considering that cyanobacteria cells contain air sacs that provide buoyancy, allowing them to stay in the illuminated area of ​​the surface of the water body for a long time. When setting up the floating board, this characteristic of cyanobacteria needs to be taken into account to ensure that the floating board can effectively intercept the cyanobacteria floating on the water surface. Therefore, this embodiment also includes: a number of piles, which are pre-driven into designated positions of rivers and lakes according to the laying area, that is, the bottom of the pile is pre-buried in the mud layer of the river and lake, and the top is partially exposed to the water surface. The top of the pile is connected to the floating frame 1 through a quick installation structure to achieve temporary positioning of the floating frame.

[0035] This embodiment uses a quick installation structure to achieve a detachable connection between the floating frame 1 and the pile column. The purpose is to achieve the positioning setting of the floating frame 1 to overcome wind force, water buoyancy and cyanobacteria buoyancy. At the same time, it is also for the convenience of installation and disassembly to achieve the reuse of the floating photovoltaic algae control and oxygenation system. That is, after the current water area is controlled, the algae disappear or the area is stable in the short term, the floating photovoltaic algae control and oxygenation system can be quickly disassembled. The disassembled floating photovoltaic algae control and oxygenation system can be transferred to other waters and reinstalled and reused using the quick disassembly structure.

[0036] Combination Figure 3The quick installation structure in this embodiment includes: a fixing pin 101 embedded in the top of the pile column, the top surface of the fixing pin 101 is sunken from top to bottom to a predetermined depth to form a stepped cavity 102. On the outside, an annular limiting protrusion 103 is arranged on the top, and a plurality of columnar grooves 104 are arranged at equal distances below the annular limiting protrusion 103, and a ball 105 is movably placed in each columnar groove 104.

[0037] The outer wall of the fixing pin 101 is also fixed with a clamping sleeve 106, and the clamping sleeve 106 is elastically connected with a sleeve 107 through a spring 108. The sleeve 107 is further movably sleeved on the fixing pin 101. Correspondingly, the inner wall of the sleeve 107 is provided with an annular operating protrusion 109, and the inner wall of the annular operating protrusion 109 is a wedge-shaped structure.

[0038] The device also includes a latch 110 having a contact end 110-a and an operating end 110-b, such as Figure 4 As shown, the outer diameter of the operating end 110-b is greater than the outer diameter of the abutting end 110-a. An annular groove 110-c is provided at a designated position on the outer wall of the abutting end 110-a, and an operating hole adapted to the operating end 110-b is reserved at a designated position on the floating frame 1. The inner diameter of the operating hole is equal to the outer diameter of the operating end 110-b. When in use, the latch 110 passes through the operating hole on the floating frame 1, so that the operating end 110-b is movably located in the operating hole, and the abutting end 110-a is located in the stepped cavity 102 as required.

[0039] Combination Figure 4 and Figure 5 When locked, the contact end 110-a of the pin 110 is completely located in the stepped cavity 102, the ball 105 is clamped with the annular groove 110-c, the spring 108 is reset, and the sleeve 107 moves upward to squeeze the annular operating protrusion 109 to squeeze the ball 105; when disassembling, external force acts on the pin 110 (pulling it upward), and the ball 105 is forced to move outward and reversely squeeze the annular operating protrusion 109. Due to the wedge-shaped structure, the sleeve 107 moves downward until the ball 105 is completely disengaged from the annular groove 110-c, and the spring 108 is in a compressed state.

[0040] In another embodiment, the transmission assembly 2 includes: two sets of guide rails 201 arranged on the upper surface of both sides of the floating frame 1 along the length direction, and two sets of sliding assemblies respectively arranged on the corresponding guide rails 201. In order to achieve real-time adjustment of the state of the mounting plate, firstly, a rack 202 is arranged along the length direction at the inner wall of the floating frame 1, and then an active trolley 203 adapted to the rack 202, at least one set of driven trolleys 204, a positioning trolley 205 and at least three sets of trusses 206 are arranged. The connection relationship between the truss 206 and the trolley can be referred to Figure 2It is understood that in the two sets of sliding components, the active trolley 203 is connected to the active trolley 203, the driven trolley 204 is connected to the driven trolley 204, and the positioning trolley 205 is connected to the positioning trolley 205.

[0041] In order to realize the association of the trusses 206 and drive all the photovoltaic panels in the floating frame 1 at the same time, the photovoltaic assembly 3 includes: a plurality of articulated assemblies arranged in parallel between two adjacent trusses 206; each articulated assembly includes: a first mounting plate 301 and a second mounting plate 302 that are articulated to each other, and the other sides of the first mounting plate 301 and the second mounting plate 302 are respectively articulated to the adjacent trusses 206. Among them, a plurality of positioning grooves are arranged on the first mounting plate 301 and the second mounting plate 302, and the positioning grooves are arranged to install solar panels 4 of corresponding sizes.

[0042] The direction of the active trolley 203 is the head end, and the direction of the positioning trolley 205 is the end end. When in use, the active trolley 203 is used as a power source to simultaneously control the position and angle of the mounting plate connected to it, and simultaneously realize the head end positioning; the driven trolley 204, under the joint action of the power trolley and the articulated assembly, simultaneously controls the position and angle of the mounting plate between the driven trolley 204 and the driven trolley 204 / positioning trolley 205; the positioning trolley 205 is used to realize the positioning connection of the last articulated assembly, that is, the end positioning.

[0043] For example, when the photovoltaic panels need to be laid out in the largest area, the active trolley 203 leads the corresponding hinge assembly, and the corresponding hinge assembly leads the driven trolley 204, and so on, the first mounting plate 301 and the second mounting plate 302 in the hinge assembly are stretched and laid out in sequence. Conversely, when the photovoltaic panels need to be stored and part of the water surface is exposed, the active trolley 203 is controlled to move in the opposite direction, leading the corresponding hinge assembly, and the corresponding hinge assembly leads the driven trolley 204, and so on, the first mounting plate 301 and the second mounting plate 302 in the hinge assembly are folded in sequence, and the folding angle can be determined according to the needs.

[0044] In order to meet the above requirements, Figure 5 and Figure 6 The active trolley 203 shown includes: a main bearing plate 203-a, on the inner side of which a main mounting plate 203-b is vertically fixed. A driving motor 203-c is installed on the upper surface of the main bearing plate 203-a, and at least four groups of guide wheels 203-d are arranged on the lower surface of the main bearing plate 203-a. This embodiment takes four groups as an example. The four groups of guide wheels 203-d are symmetrically arranged on both sides of the guide rail 201 in pairs, and are in surface contact with the guide rail 201.

[0045] A rotatable rotating gear 203-e is installed on the outer wall of the main mounting plate 203-b, and the rotating gear 203-e is transmission-connected to the output shaft of the driving motor 203-c and meshes with the rack 202. In this embodiment, the transmission connection between the rotating gear 203-e and the output shaft of the driving motor 203-c can be achieved through the gear rack 202, which is not described in detail here.

[0046] In order to ensure the stability of movement, a number of rotatable support wheels 203-f are also installed on the outer wall of the main mounting plate 203-b. The rolling surface of the support wheel 203-f is in contact with the floating frame 1 to provide a certain supporting force to increase stability.

[0047] When the active trolley 203 moves toward the head end, if it cannot stop moving quickly when it is about to reach the head end, it will not only cause damage to the trolley itself, but also cause the connection between the first mounting plate 301 and the second mounting plate 302 in the hinge assembly to break due to excessive pulling, causing irreversible damage.

[0048] Therefore, the active vehicle 203 also includes: a limit switch 207 arranged in the forward direction, which is used to sense the floating frame 1 and send a signal to shut down the driving motor 203-c. Figure 7 As shown, the limit switch 207 includes: a body 207-a installed at the head end of the main mounting plate 203-b, a bracket 207-b fixed on the body 207-a at a predetermined angle by a tensioning bolt on the body 207-a, and an infrared sensor 207-d is installed above the bracket 207-b. When in use, when the bracket 207-b maintains the predetermined angle unchanged, the infrared sensor 207-d detects that there is no obstruction; if the bracket 207-b rotates clockwise due to an external force of the trigger bar 207-c, the infrared sensor 207-d detects that there is an obstruction, and the trigger signal turns off the drive motor 203-c. It can effectively protect the active trolley 203 and other components of the floating photovoltaic algae control and oxygenation system and extend the service life.

[0049] In order to reduce the wear on the trigger bar 207-c, 207-e is installed at its head end.

[0050] In another embodiment, in combination Figure 8 The driven trolley 204 includes: a secondary bearing plate 204-a, on the inner side of which a secondary mounting plate 204-b is vertically fixed; at least four sets of guide wheels 203-d are arranged on the lower surface of the secondary bearing plate 204-a; the guide wheels 203-d are symmetrically arranged in pairs on both sides of the guide rail 201 and are in surface contact with the guide rail 201; a plurality of support wheels 203-f are rotatably mounted on the outer wall of the secondary mounting plate 204-b; the rolling surface of the support wheel 203-f is in contact with the floating frame 1.

[0051] Correspondingly, the positioning trolley 205 of this embodiment is based on the driven trolley 204 and has a fixed block 205-a, which is fixedly mounted on the floating frame 1 and located at the head end of the positioning trolley 205 to achieve long-term positioning. Fig. 9 shown.

[0052] Considering that the driven trolley 204 is prone to movement due to its unconstrained positioning, when the driven trolley 204 stops at a certain position, it is forced to drive the truss 206 to move, such as in the case of strong wind. Any uncontrolled movement of the driven trolley 204 will directly cause the connection of the mounting plate connected to it to break, especially when the photovoltaic panel is tilted.

[0053] In order to solve the above technical problems, in another embodiment, the driven trolley 204 is further provided with a positioning assembly. Fig. 9 As shown, the positioning assembly includes: a connecting frame 204-c fixed on the auxiliary bearing plate 204-a, and a pushing cylinder 204-d is hinged on the connecting frame 204-c. It also includes: a clamping plate 204-e with one end hinged on the auxiliary mounting plate 204-b, and the clamping plate 204-e is also hinged with the output end of the pushing cylinder 204-d. When the pushing cylinder 204-d is ejected, the other end of the clamping plate 204-e contacts the side of the guide rail 201, and positioning is achieved by increasing friction. When the driven trolley 204 moves, the pushing cylinder 204-d is in a compressed state.

[0054] Example 2 Based on the floating photovoltaic algae control and oxygenation system disclosed in Example 1, this embodiment discloses an application method of the floating photovoltaic algae control and oxygenation system, including the following steps: Piles are driven into the algae-infested areas of rivers and lakes, and floating frames of predetermined sizes are laid using a quick-installation structure. Transmission components, photovoltaic components and aeration devices are assembled in sequence. This assembly process increases the stability of the floating frame, especially to overcome the buoyancy of the algae, and secondly, enables reuse through detachable connections.

[0055] When algae erupts, the transmission assembly drives the photovoltaic assembly to be laid horizontally, that is, the photovoltaic panels are connected to each other first, effectively separating sunlight from algae. That is, the transmission assembly drives the active trolley to move to the head end until the photovoltaic panel is in a horizontal position, and the clamping assembly is used to position each group of driven trolleys.

[0056] When the water body under the photovoltaic panel or the photovoltaic panel itself is operated as required, the corresponding transmission assembly is selected to drive the photovoltaic panels in the photovoltaic assembly to be laid at a predetermined angle, that is, the photovoltaic panels are gathered together to expose part of the water body; At the same time, the photovoltaic panel absorbs light to generate light energy, and the light energy is input into the aeration device through the electrical connection and the conversion element as the power source of the aeration device, driving the aeration device to oxygenate the oxygen-deficient bottom water body.
