Description

[0001] The present invention relates to the technical field of photovoltaic panels, and in particular to a solar photovoltaic regulating device and a use method thereof. Background Art

[0002] A solar photovoltaic system refers to a facility that uses the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of the photovoltaic facility is the solar photovoltaic panel, which is a device that directly converts sunlight energy into electrical energy due to the photovoltaic effect.

The present invention drives the operation of the plurality of angle adjustment mechanisms through a driving mechanism, thereby driving the plurality of photovoltaic panels to rotate upward by 45°, so that a 90° angle is formed between the two photovoltaic panels of each group, so that the light is obliquely irradiated on the surface of the photovoltaic panel. Compared with vertical irradiation, oblique irradiation can reflect a part of the light, so that the light intensity received by the photovoltaic panel is appropriately reduced, the heating of the photovoltaic panel is reduced, and the power generation efficiency of the photovoltaic panel is prevented from decreasing.

[0004] Based on the above search and combined with actual practice, it can be known that in the prior art, by adjusting the angle between the two photovoltaic panels to 90°, the light is irradiated obliquely on the surface of the photovoltaic panel. Compared with vertical irradiation of the light, the heating of the photovoltaic panel can be reduced. Although this method can reflect part of the light, the light on the two photovoltaic panels will also reflect each other, causing part of the light to be converted into heat energy, causing the photovoltaic panel to heat up and reducing the power generation efficiency.

[0009] As a further improvement of the present technical solution, the partition divides the air storage chamber inside the air storage box into two identical chambers, wherein the chamber is divided into a left chamber and a right chamber, the left chamber and the right chamber are respectively connected with an air duct and an air supply pipe, and a first one-way valve is arranged in the air duct and the air supply pipe. The first one-way valve in the air duct is used to supply the air in the left chamber to enter the jet box, and the tops of the left chamber and the right chamber are both connected with an air intake pipe, and a second one-way valve is arranged in the air intake pipe for external air to enter the two chambers.

[0010] As a further improvement of the present technical solution, the end of the air pipe is connected to a water tank fixed on the support plate, and the connection between the air pipe and the water tank is located above the water tank. The bottom of the water tank is connected to a sprinkler fixed on the upper end of the outer frame through a pipeline, and the sprinkler has multiple nozzles to utilize the air entering the water tank to pressurize the water, and the sprayed water cleans the dust on the upper photovoltaic panel.

[0011] As a further improvement of the present technical solution, when the water flows from the upper photovoltaic panel to the lower photovoltaic panel, a water curtain is formed at the air flow channel to restrict the flow of the air flow, so that the air flow flows to both sides of the photovoltaic panel to clean the dust on the end surface of the photovoltaic panel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the solar photovoltaic adjustment device, the rotation of the upper and lower photovoltaic panels is controlled by a power mechanism. By adjusting the angle between the photovoltaic panel and the light so that it is not completely perpendicular to the incident light, part of the light will be reflected or scattered on the surface of the photovoltaic panel, reducing the directly absorbed heat energy, which helps to maintain the photovoltaic panel at a relatively stable operating temperature. In addition, an air flow channel is formed between the upper and lower photovoltaic panels for the circulation of the jet box and external air, reducing the heat on the back of the upper photovoltaic panel and the front of the lower photovoltaic panel, thereby improving the heat dissipation effect of the photovoltaic panel.

[0015] 2.

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. 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.

[0020] First, in the prior art, by adjusting the angle between the two photovoltaic panels 102 to 90°, the light is irradiated obliquely on the surface of the photovoltaic panel 102. Compared with vertical irradiation of the light, the heating of the photovoltaic panel 102 can be reduced. Although this method can reflect part of the light, the light on the two photovoltaic panels 102 will also reflect each other, causing part of the light to be converted into heat energy, causing the photovoltaic panel 102 to heat up, thereby reducing the power generation efficiency.

[0021] Therefore, if Figure 1-Figure 8 As shown, a solar photovoltaic adjustment device is provided to solve the above problems, comprising an outer frame 100 and two upper and lower inner frames 101 surrounded by the outer frame 100, each inner frame 101 is embedded with a photovoltaic panel 102, and the inner frame 101 is rotatably connected to the outer frame 100, a support plate 103 is fixedly connected to the bottom of the outer frame 100, and a power mechanism 110 for controlling the synchronous rotation of the two inner frames 101 is arranged on the support plate 103, and the support plate 102 at the bottom of the upper inner frame 101 is fixedly connected to the bottom of the outer frame 100. 3 is provided with a gas storage box 120 for storing gas, the gas storage box 120 is connected with an injection box 121 fixed at the bottom of the upper inner frame 101, the injection box 121 has air holes, and the gas storage box 120 is provided with an exhaust mechanism 130 fixedly connected to the upper inner frame 101. When the upper and lower photovoltaic panels 102 rotate, an air flow channel is formed between the upper and lower photovoltaic panels 102. The air ejected from the injection box 121 passes through the air flow channel, so that the air at the bottom of the photovoltaic panel 102 circulates to dissipate heat from the photovoltaic panel 102.

[0022] Under normal conditions, the upper and lower photovoltaic panels 102 maintain an angle of 45° with the horizontal ground. At noon in summer, the light intensity is very strong, and the power generation efficiency of the photovoltaic panel 102 is not in a stable positive correlation with the light intensity. If the light intensity is too high, not only will the power generation efficiency fail to be improved, but it will also easily cause the photovoltaic panel 102 to overheat, thereby reducing the power generation efficiency. Therefore, the upper and lower photovoltaic panels 102 are controlled to rotate by the power mechanism 110, and the angle between the photovoltaic panel 102 and the light is adjusted so that it is not completely perpendicular to the incident light. Part of the light will be reflected or scattered on the surface of the photovoltaic panel 102, reducing the directly absorbed heat energy, which helps to maintain the photovoltaic panel 102 at a relatively stable operating temperature. In addition, an air flow channel is formed between the upper and lower photovoltaic panels 102, which can provide circulation for the jet box 121 and external air, reduce the heat on the back of the upper photovoltaic panel 102 and the front of the lower photovoltaic panel 102, and improve the heat dissipation effect of the photovoltaic panel 102.

[0023] It should be noted that when the photovoltaic panel 102 needs to rotate, the temperature of the photovoltaic panel 102 can be detected by an external temperature control system, and the start and stop of the power mechanism 110 can be controlled by setting a temperature threshold.

[0024] Secondly, on the basis of the above, the specific structure of the power mechanism 110 is first disclosed. The power mechanism 110 includes a power motor 111 fixed on the support plate 103 and a belt 112 driven by the output shaft of the power motor 111. The belts 112 are respectively connected to pulleys 113 fixedly connected to the middle of the frame of the inner frame 101. When adjusting the angle between the photovoltaic panel 102 and the light, the upper and lower photovoltaic panels 102 rotate synchronously, and then combined with Figure 7 As shown, by creating gaps between the upper and lower photovoltaic panels 102 and increasing the distance between the gaps, an airflow channel is formed to allow air to flow through the airflow channel.

[0025] Because the photovoltaic panel 102 generates a certain amount of heat during operation, the temperature around the photovoltaic panel 102 increases. When there is wind in the external environment, air can flow through the airflow channel, which helps to dissipate the heat of the photovoltaic panel 102. Good heat dissipation can improve the efficiency and life of the photovoltaic system.

[0026] Furthermore, during the rotation of the upper inner frame 101 (the rotation direction of the inner frame 101 is as follows Figure 6 As shown by the arrow in the figure), the inner frame 101 pulls the exhaust mechanism 130 to make the air in the air storage box 120 eject from the ejection box 121. Figure 4As shown, the structure of the exhaust mechanism 130 is publicly described, the exhaust mechanism 130 includes a push plate 131 which is sleeved with the inside of the gas storage box 120, a tension spring 134 is elastically connected between the bottom of the push plate 131 and the inner wall of the gas storage box 120, a partition 132 which penetrates the gas storage box 120 is fixedly connected to the upper middle part of the push plate 131, a traction rope 133 is connected between the top of the partition 132 and the bottom of the upper inner frame 101, and the connection between the traction rope 133 and the inner frame 101 is close to the border of the inner frame 101. The purpose of this is: with the help of the connection between one end of the traction rope 133 and the inner frame 101 being close to the border of the inner frame 101, that is, the connection is located at the farthest end of the inner frame 101, any slight angle adjustment will cause a significant change in the length of the traction rope 133, thereby ensuring the sensitivity and response speed of the traction rope 133 to the posture change of the inner frame 101, so that more air is discharged from the chamber.

[0027] On the other hand, the partition 132 divides the air storage cavity inside the air storage box 120 into two identical chambers, wherein the chamber is divided into a left chamber and a right chamber, and the left chamber and the right chamber are respectively connected with an air duct 122 and an air supply pipe 123, and the air duct 122 and the air supply pipe 123 are both provided with a first one-way valve 124, and the first one-way valve 124 in the air duct 122 is used to supply the air in the left chamber to enter the jet box 121, and the tops of the left chamber and the right chamber are both connected with an air intake pipe, and the air intake pipe is provided with a second one-way valve 125 for external air to enter the two chambers.

[0028] Specifically during operation: when the upper inner frame 101 rotates, the inner frame 101 pulls the traction rope 133 to move, and with the help of the traction rope 133 and the partition 132, the push plate 131 moves upward inside the air storage box 120, and the push plate 131 discharges the air in the chamber through the air duct 122 and the air delivery pipe 123. At this time, the second one-way valve 125 in the air intake pipe is in a closed state. For the air in the left chamber, the air is transported to the jet box 121 through the air duct 122. The air ejected from the jet box 121 is parallel to the bottom of the inner frame 101, and the air passes from one end of the frame of the inner frame 101 to the other end, which helps to reduce the heat accumulation at the bottom of the inner frame 101 and improve the heat dissipation effect of the photovoltaic panel 102.

[0029] When the photovoltaic panel 102 rotates in the reverse direction to reset, the elastic potential energy of the tension spring 134 is used to pull the push plate 131 downward, and the push plate 131 draws external air into the chamber through the air inlet pipe for the next use.

[0030] As the inner frame 101 rotates, the upper and lower photovoltaic panels 102 rotate to Figure 7In the state shown, during this process, the air in the right chamber is discharged from the air pipe 123, and the end of the air pipe 123 is connected to a water tank 150 fixed on the support plate 103, and the connection between the air pipe 123 and the water tank 150 is located above the water tank 150, and the lower part of the water tank 150 is connected to a sprinkler 151 fixed on the upper end of the outer frame 100 through a pipeline, and the sprinkler 151 has a plurality of nozzles, so as to use the air entering the water tank 150 to pressurize the water, and the sprayed water cleans the dust on the upper photovoltaic panel 102, and then returns to Figure 7 As shown, after the water flow washes the dust on the upper photovoltaic panel 102, the water flow slides along the upper photovoltaic panel 102 to the lower photovoltaic panel 102. The stepped water flow can ensure that the water flow passes through more surfaces of the photovoltaic panels 102, which can more comprehensively clean the surface dust and reduce the waste of water resources.

[0031] It should be noted that: when the photovoltaic panel 102 rotates slightly, the displacement of the push plate 131 is short. In order to ensure that the air sprayed from the jet box 121 and the water flow sprayed from the sprinkler 151 can maintain a normal state, the water flow in the water tank 150 and the gas sprayed from the jet box 121 can be pressurized by an external booster device, and the booster device plays an auxiliary role, which belongs to the prior art and will not be described in detail.

[0032] In addition, due to the effect of inertia and the fact that the upper and lower photovoltaic panels 102 are parallel, but the photovoltaic panels 102 are not on the same straight line, the water flowing from the upper photovoltaic panel 102 cannot completely cover the lower photovoltaic panel 102, that is, there is an area where the water cannot flow through the end of the lower photovoltaic panel 102 close to the upper photovoltaic panel 102. Therefore, when the water flows from the upper photovoltaic panel 102 to the lower photovoltaic panel 102, a water curtain is formed at the airflow channel to restrict the flow of the airflow, so that the airflow flows to both sides of the photovoltaic panel 102 to clean the dust on the end surface of the photovoltaic panel 102. In this way, when the airflow in the airflow channel passes, the airflow will encounter the obstruction of the water curtain. Due to the density and continuity of the water curtain, the airflow is forced to change its original flow direction and no longer moves in a straight line, but is diverted to both sides of the channel. As the airflow flows to both sides, the airflow will carry the dust particles on the surface of the photovoltaic panel 102 together. These dust particles originally adhere to the surface of the photovoltaic panel 102, affecting the photoelectric conversion efficiency. However, driven by the airflow, the dust particles are gradually peeled off and taken away from the surface of the photovoltaic panel 102 along with the airflow, thereby achieving the effect of cleaning the dust on the end surface of the photovoltaic panel 102 and improving the light energy conversion efficiency of the photovoltaic panel 102.

[0033] Moreover, air guide plates 140 fixedly connected to the outer frame 100 are provided on both sides of the lower photovoltaic panel 102, the sides of the photovoltaic panel 102 are fitted with the air guide plates 140, the upper end of the air guide plates 140 is in a closed state, and the bottom of the air guide plates 140 rotates outward to form an arc-shaped air guide groove 141 for guiding the airflow flowing to the two sides of the photovoltaic panel 102 to the back of the photovoltaic panel 102. By guiding the airflow flowing to the two sides of the photovoltaic panel 102 to the back of the photovoltaic panel 102, the flow of the airflow can be used to take away the heat accumulated on the back of the photovoltaic panel 102, thereby reducing the temperature of the photovoltaic panel 102 and improving the power generation efficiency.

[0034] The second object of the present invention is to provide a method for using a solar photovoltaic regulating device, comprising the following steps: S1. During the rotation of the upper inner frame 101, the inner frame 101 pulls the traction rope 133 to move, and the push plate 131 moves upward inside the air storage box 120 with the help of the traction rope 133 and the partition 132. The air ejected from the jet box 121 passes from one end of the frame of the inner frame 101 to the other end, which helps to reduce the accumulation of heat at the bottom of the inner frame 101 and improve the heat dissipation effect on the photovoltaic panel 102; S2. After washing the dust on the upper photovoltaic panel 102, the water flows along the upper photovoltaic panel 102 to the lower photovoltaic panel 102. The stepped water flow can ensure that the water flows through more surfaces of the photovoltaic panels 102, which can more comprehensively clean the surface dust and reduce the waste of water resources. S3. When the airflow in the airflow channel passes through, the airflow will be blocked by the water curtain and will be diverted to both sides of the channel. As the airflow flows to both sides, the airflow will carry the dust particles on the surface of the photovoltaic panel 102 with it; S4. The airflow flowing toward the two sides of the photovoltaic panel 102 is guided to the back of the photovoltaic panel 102 by the air guide plate 140. The flow of the airflow can be used to take away the heat accumulated on the back of the photovoltaic panel 102, thereby reducing the temperature of the photovoltaic panel 102 and improving the power generation efficiency.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.

A method for operating a solar photovoltaic regulating device according to any one of claims 3 to 7, characterized in that: The method comprises the following steps: S1, during the rotation of the upper inner frame (101), the inner frame (101) pulls the traction rope (133) to move, and the push plate (131) is moved upward inside the air storage box (120) by means of the traction rope (133) and the partition plate (132), and the air ejected from the jet box (121) passes from one end of the frame of the inner frame (101) to the other end, which helps to reduce the accumulation of heat at the bottom of the inner frame (101) and improve the heat dissipation effect on the photovoltaic panel (102); S2, after the water flow washes away the dust on the upper photovoltaic panel (102), the water flow slides along the upper photovoltaic panel (102) to the lower photovoltaic panel (102). The stepped water flow can ensure that the water flow passes through more surfaces of the photovoltaic panels (102), thereby more comprehensively washing away the dust on the surfaces and reducing the waste of water resources; S3. When the airflow in the airflow channel passes through, the airflow will be blocked by the water curtain and will be split to the two sides of the channel. As the airflow flows to the two sides, the airflow will carry the dust particles on the surface of the photovoltaic panel (102) with it; S4. The airflow flowing toward the two sides of the photovoltaic panel (102) is guided to the back of the photovoltaic panel (102) by using the air guide plate (140). The heat accumulated on the back of the photovoltaic panel (102) can be taken away by the flow of the airflow, thereby reducing the temperature of the photovoltaic panel (102) and improving the power generation efficiency.
