[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model relates to an integrated adaptive photovoltaic panel cleaning and heat dissipation device, comprising a photovoltaic panel and a support frame.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] In the first embodiment, as Figure 1-3 As shown, this utility model provides an integrated adaptive photovoltaic panel cleaning and heat dissipation device, including a photovoltaic panel 1 and a support frame 101. The support frame 101 is fixedly supported on the lower side of the photovoltaic panel 1. An air duct chamber 2 is installed between the photovoltaic panel 1 and the support frame 101. An air pump 201 is installed at the bottom of the air duct chamber 2. A sliding member 3 is installed on the upper part of the air duct chamber 2 at an inclined angle. The sliding member 3 has a U-shaped structure and is slidably embedded on the upper part of both sides of the air duct chamber 2. A covering groove 4 is installed on the top of the sliding member 3. It has a C-shaped structure, with the top of the covering groove 4 located on the upper side of the photovoltaic panel 1. A sealing strip 102 is installed on the top of the photovoltaic panel 1. A micro motor 103 is provided inside the sealing strip 102. A screw 104 and a threaded sleeve 105 are axially installed on the surface of the screw 104. The threaded sleeve 105 is fixedly installed on the surface of the sliding member 3. The air duct 2 has internal air holes 202 on both sides, and the sliding member 3 has external air holes 301 on both sides. The positions of the internal air holes 202 and the external air holes 301 are correspondingly set.

[0026] To enable the photovoltaic panel 1 to adjust its cleaning and heat dissipation according to its own structure, a sliding member 3 is provided that moves up and down along the air duct chamber 2. Under normal conditions, the inner air hole 202 and the outer air hole 301 correspond to each other. The top covering groove 4, together with the top sealing strip 102 of the photovoltaic panel 1, seals the inside of the air duct chamber 2. After the air pump 201 is started, it will generate heat dissipation for the photovoltaic panel 1 from both sides to accelerate the heat dissipation efficiency of the bottom of the photovoltaic panel 1. When it is necessary to remove dust from the photovoltaic panel 1, the sliding member 3 is moved up to make the outer air hole 301 and the inner air hole 202 misaligned to seal the exhaust channels on both sides. The internal air pressure mainly moves from the air duct chamber 2 to the covering groove 4. At this time, the sealing strip 102 and the inner wall of the covering groove 4 separate, and the wind force will be concentrated from the top of the covering groove 4 to blow towards the surface of the photovoltaic panel 1 to form a rapid dust-blowing effect on the surface of the photovoltaic panel 1.

[0027] In a further embodiment, the upper and lower sides of the inner air hole 202 are provided with sliding grooves 203, and the upper and lower sides of the outer air hole 301 are provided with sliding rails 302. The sliding rails 302 and the sliding grooves 203 are slidably connected. Its structure allows the sliding member 3 to limit the structure in other directions when it slides on the surface of the air duct chamber 2, and the surface sliding member 3 falls off the air duct chamber 2.

[0028] In a further embodiment, the width of the photovoltaic panel 1 is the same as the inner diameter of the sliding member 3, the inner diameter of the sliding member 3 is uniform at the front and back, the width of the photovoltaic panel 1 is also the same as that of the air duct chamber 2, the photovoltaic panel 1 and the sealing strip 102 are of the same length, and the photovoltaic panel 1 and the sealing strip 102 are fixedly connected. The sealing strip 102 is made of metal material, and a sealing rubber ring is provided at the top of the sealing strip 102. The upper bottom of the air duct chamber 2 is provided with a slot 204, and an insert plate 401 is installed at the bottom of the covering groove 4. The insert plate 401 and the slot 204 are slidably inserted into each other.

[0029] To ensure a seal within the air duct chamber 2 when the sliding member 3 is closed, the width of the photovoltaic panel 1 is matched to the width of the air duct chamber 2, and the inner diameter of the sliding member 3 is also consistent. Furthermore, the sealing strip 102 is equipped with a sealing rubber ring. Due to the self-limiting nature of the sliding member 3, when the micro motor 103 starts, the screw 104 will rotate inside the sliding member 3, allowing the sliding member 3 to move up and down along the air duct chamber 2. This compresses the sealing rubber ring, causing the lower part of the covering groove 4 to cooperate with the air duct chamber 2 to form a seal. The insert plate 401, located on the outside, is inserted into the slot 204. Side plates are also provided on both sides of the sliding member 3, allowing internal airflow to flow along... Figure 3 The form is upward.

[0030] In a further embodiment, the support frame 101 is provided with an extension rod 5 at the top. The extension rod 5 extends from the bottom of the air duct chamber 2 to the upper part of the air duct chamber 2. The extension rod 5 is used to support the interior of the air duct chamber 2. The support frame 101 is inclined or trapezoidal along the bottom of the air duct chamber 2. The air outlet of the air pump 201 is inclined upward along the interior of the air duct chamber 2.

[0031] Its structure allows the top of the support to be located inside the air duct chamber 2 to form a fixed structure, preventing deformation inside the air duct chamber 2 due to different levels of wind pressure; in particular, in order to be versatile, the photovoltaic panel 1 will be used on the roof or the ground, so in order to adapt to different support frames 101, an extension rod 5 is provided to facilitate the formation of a support structure for the photovoltaic panel 1.

[0032] In a further embodiment, the photovoltaic panel 1 and the air duct chamber 2 are fixedly connected, and the upper side of the air duct chamber 2 is tightly fitted to the bottom of the photovoltaic panel 1; the photovoltaic panel 1 also includes a main control unit, which is electrically connected to the air pump 201 and the micro motor 103 respectively. The main control unit is used to control the power adjustment of the air pump 201 and the micro motor 103; the main control unit includes: a voltage regulator, a central processing unit, a storage device, a wireless connection module, and a temperature sensor, wherein the temperature sensor is located at the lower part of the photovoltaic panel 1;

[0033] To monitor the photovoltaic panel 1, a main control unit and a temperature sensor are provided. If necessary, a gravity sensor, a light bed sensor, or a camera can also be installed to monitor whether the irradiance decreases. The temperature sensor primarily senses the temperature of the photovoltaic panel 1. The temperature of a conventional photovoltaic panel 1 has a certain threshold, which depends on the local environment and is therefore set by the user through the main control unit. When the temperature is high, the air duct chamber 2 is generally only used as a heat dissipation structure. When the temperature of the photovoltaic panel 1 is too high or too low, it is generally because the surface of the photovoltaic panel 1 is heating up but cannot dissipate heat, or most of the surface of the photovoltaic panel 1 is covered and cannot directly contact the light, such as with snow. In this case, the main control unit will drive the micro motor 103 to start, causing the inner wall of the covering groove 4 to separate from the sealing strip 102. The insert plate 401 will also move out of the slot 204 and out of the lower part of the outer sealing covering groove 4. Because the pressure of the air pump 201 inside the air duct chamber 2 increases, but the outlet path between the upper part of the covering groove 4 and the photovoltaic panel 1 narrows, such as... Figure 3 As shown, if necessary, the distance between the covering groove 4 and the sealing strip 102 can be further reduced so that the increased wind pressure will blow away foreign objects such as dust from the surface of the photovoltaic panel 1 more quickly, thus avoiding long-term coverage of the photovoltaic panel 1 surface.

[0034] In another embodiment, the coating tank 4 can also be connected to a water tank, which has a spray structure extending to the upper part of the coating tank 4, so that it can achieve rapid spraying and cleaning effect in conjunction with wind pressure when blown by high-speed wind pressure.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
