Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, a solar-powered electrocatalytic oxidation device for black and odorous water bodies in lakes and rivers includes a solar power generation device 1, an energy storage device 2, and an electrocatalytic oxidation device 3 connected by a circuit. During peak power generation periods, a portion of the electricity generated by the solar power generation device 1 is supplied to the electrocatalytic oxidation device 3, and the excess electricity is stored in the energy storage device 2. When the solar power generation device 1 is in a low-power period, the electricity generated is insufficient to supply the electrocatalytic oxidation device 3, and the electricity stored in the energy storage device 2 can be supplied to the electrocatalytic oxidation device 3.

[0030] like Figure 2As shown, the solar power generation device comprises a base 101, the base 101 is provided with a mounting rack 102, the mounting rack 102 is flatly installed, and the mounting rack 102 is provided with a rearwardly bent side plate 103 on the left and right sides in the width direction respectively; a photovoltaic panel 104 is fixedly installed on the front side of the mounting rack 102, the photovoltaic panel 104 converts sunlight into electric energy; the outer side of the lower end of each of the two side plates 103 is welded with a horizontally extending rotating shaft 105, the top front end of the base 101 is fixedly installed with two supports 106 which are oppositely arranged, and the rotating shaft 105 is rotatably installed on the corresponding support 106. A first telescopic component for adjusting the angle of the mounting rack 102 is hingedly connected between the base 101 and the mounting rack 102, the first telescopic component is a gas cylinder 107, one end of the gas cylinder 107 is hingedly connected to the top rear end of the base 101, the other end is hingedly connected to the side plate 103, and the mounting rack 102 can be swung forward and backward by the extension and contraction of the gas cylinder 107, thereby adjusting the angle of the photovoltaic panel 104, so as to adjust the photovoltaic panel 104 according to the angle of the sunlight, and improve the photoelectric conversion efficiency of the photovoltaic panel.

[0031] The mounting rack 102 is also provided with a movable rack driven by a power device and moving along the height direction of the mounting rack 102, the movable rack comprises a transversely extending horizontal plate 108, the horizontal plate 108 is located on the side of the mounting rack 102 provided with the photovoltaic panel 104 and is arranged in parallel with the mounting rack 102, the left and right ends of the horizontal plate 108 are integrally bent and formed with a connecting plate 109 arranged perpendicularly thereto, the mounting rack 102 is provided with a strip-shaped hole 110 through which the connecting plate 109 passes, the photovoltaic panel 104 is located between the two strip-shaped holes 110, and the length direction of the strip-shaped hole 110 extends along the height direction of the mounting rack 102; the movable rack is provided with an activity plate 111 fixedly installed between the two connecting plates 109 by bolts, as shown, Figure 3 The activity plate 111 is located on the side of the mounting rack 102 away from the photovoltaic panel 104, the side of the mounting rack 102 away from the photovoltaic panel 104 is provided with a slide rod 112 extending along the height direction of the mounting rack 102, the slide rod 112 is arranged in parallel with the two slide rods 112, the two ends of the slide rod 112 are fixedly installed on the mounting rack 102 through the fixing seat, and the activity plate 111 is slidingly installed on the two slide rods 112, and the slide rod 112 provides a guiding action for the movement of the movable rack.

[0032] The power device comprises a motor 113 installed on the side of the mounting rack 102 away from the photovoltaic panel 104 by bolts, the output end of the motor 113 is provided with a lead screw 114 arranged in parallel with the slide rod 112, one end of the lead screw 114 away from the motor 113 is rotatably connected to the mounting rack 102 through a bearing seat, and the activity plate 111 is threadedly connected to the lead screw 114. The lead screw 114 is driven to rotate by the motor 113, and then the lead screw 114 drives the activity plate 111 and the movable rack to move along the height direction of the mounting rack 102.

[0033] A flushing pipe 115 for rinsing the photovoltaic panel 104 is bolted between two connecting plates 109. The flushing pipe 115 is located on the side of the mounting frame 102 where the photovoltaic panel 104 is located. The flushing pipe 115 extends laterally, and one end of the flushing pipe 115 is equipped with a water inlet pipe 116. The water inlet pipe 116 is connected to a water source through a hose, and a water pump is installed on the water inlet pipe 116. Multiple nozzles 117 are evenly spaced on the side of the flushing pipe 115 near the photovoltaic panel 104. During use, the photovoltaic panel 104 is rinsed periodically by spraying water mist through the flushing pipe 115 to prevent dirt from adhering to the photovoltaic panel 104 and affecting the photoelectric conversion efficiency. During the rinsing process of the photovoltaic panel 104 by the flushing pipe 115, the motor 113 drives the lead screw 114 to rotate periodically in both directions. In turn, the lead screw 114 drives the movable frame to move up and down along the height direction of the mounting frame 102, thereby expanding the rinsing range of the flushing pipe 115.

[0034] The movable frame is also equipped with a scraper 118 for cleaning the photovoltaic panels 104. A laterally extending scraper seat 119 is provided between the two connecting plates 109, and the scraper 118 is embedded in one side of the scraper seat 119. The left and right ends of the scraper seat 119 are rotatably mounted on the corresponding connecting plates 109 via laterally extending mounting shafts 120. The scraper seat 119 is driven to rotate by a second telescopic component, which is an electric push rod 121. One end of the electric push rod 121 is hinged to the horizontal plate 108, and the other end is hinged to one side of the scraper seat 119. Specifically, as... Figure 5 As shown, the extension of the electric push rod 121 drives the scraper seat 119 to rotate clockwise, causing one end of the scraper 118 to be pressed downwards against the photovoltaic panel 104; conversely, as shown... Figure 6 As shown, the electric push rod 121 retracts, causing the scraper seat 119 to rotate counterclockwise. The scraper seat 119 then lifts one end of the scraper 118 upwards, separating it from the photovoltaic panel 104. In practical use, as the lead screw 114 drives the movable frame to move up and down along the height of the mounting frame 102, when the movable frame moves downwards along the height of the mounting frame 102, the electric push rod 121 extends, causing one end of the scraper 118 to press downwards against the photovoltaic panel 104. Simultaneously, the scraper 118 removes moisture and dirt from the photovoltaic panel 104 as the movable frame moves downwards along the height of the mounting frame 102. When the movable frame moves upwards along the height of the mounting frame 102, the electric push rod 121 retracts, causing one end of the scraper 118 to lift upwards, separating it from the photovoltaic panel 104. This prevents the scraper 118 from pushing dirt onto the upper part of the photovoltaic panel 104.

[0035] The electrocatalytic oxidation device 3 includes an electrode support with a stand 301. A horizontally extending crossbar 302 is fixedly mounted on the upper end of the stand 301, and an electrode is fixedly mounted on the crossbar 302. The upper end of the electrode is fixedly mounted on the crossbar 302 via an extension rod, and the electrode is submerged below the surface of the river or lake. The electrode includes an anode plate 303 and two cathode plates 304 located on opposite sides of the anode plate 303. The anode plate 303 is made of materials such as carbon felt, titanium mesh, tin dioxide, graphite, or carbon cloth, while the cathode plates 304 are made of materials such as stainless steel mesh, titanium mesh, or nickel mesh. The anode plate 303 and cathode plates 304 are connected to the positive and negative terminals of a power source, respectively. Under energized conditions, the electrodes degrade COD in the black and odorous water body, oxidizing it into CO2 and H2O. Through long-term, slow electrocatalytic oxidation, the black and odorous water body of the lake or river is improved.

[0036] A plastic fence 305 is also fixedly installed on the crossbar 302 between the anode plate 303 and the cathode plate 304 to prevent the anode plate 303 and the cathode plate 304 from short-circuiting due to contact.
