Description

Technical Field

[0001] This application relates to the technical field of photovoltaic panel heat dissipation devices, and particularly to a circulating heat dissipation device for a photovoltaic power station. Background Art

[0002] The core component of a photovoltaic power generation system is a photovoltaic module. Whether a photovoltaic module can operate normally is often affected by factors such as the material and structure of the photovoltaic panel and external conditions. And temperature is an important factor affecting the power generation efficiency of the photovoltaic panel.

[0003] Under standard test conditions, the optimal operating temperature of a photovoltaic cell is around 25°C. When the temperature of the photovoltaic panel exceeds 50°C, its photoelectric conversion efficiency will decrease. If the temperature rises above 60°C, the peak power generation capacity of the panel will be affected. Therefore, a heat dissipation device is provided on the lower side of the photovoltaic panel. Generally, the heat dissipation device is a heat dissipation pipe, and a cooling medium (such as cooling water) is introduced into it. The cooling medium flows continuously and takes away the excess heat of the photovoltaic panel through heat exchange.

[0004] During the circulation process, impurities inevitably exist in the cooling medium, whether it is scale or debris originally carried in the cooling medium. It is necessary to perform circulating filtration to remove the impurities. Therefore, a filter rod is added in the heat dissipation pipe. However, after a long time of filtration, when the load of the filter rod is too large, it still needs to be replaced. At this time, the circulating heat dissipation device needs to be paused, and the filter rod is removed from the heat dissipation pipe, which is rather troublesome. Utility Model Content

[0005] In order to replace the filter rod more conveniently, this application provides a circulating heat dissipation device for a photovoltaic power station.

[0006] A circulating heat dissipation device for a photovoltaic power station provided by this application adopts the following technical solution: A circulating heat dissipation device for a photovoltaic power station includes a heat dissipation pipe for installation on one side of a photovoltaic panel. A filter box is provided on the heat dissipation pipe, and the filter box is perpendicular to the heat dissipation pipe. The filter box includes a filtering section inside the heat dissipation pipe and spare sections provided at both ends of the filtering section. Two detachably connected filter rods are slidably arranged in the filter box in a positionable manner, and the filter rods are of the same length as the filtering section.

[0007] By adopting the above technical solution, generally, one of the filter rods is located in the heat dissipation pipe for filtration. When it is necessary to replace the filter rod after a long filtering time, generally after one month, by sliding the two filter rods synchronously, the filter rod located in the filtering section is moved into the spare section. At this time, the other filter rod replaces it, and then the previous filter rod is disassembled and replaced. There is no need to pause the circulating heat dissipation device, which is rather convenient.

[0008] Preferably, the filter element rod includes a core body, a central axis passing through the core body, and closing plates arranged at both ends of the central axis. The closing plates are used to cooperate with the outer wall of the filtering section to achieve sealing.

[0009] Preferably, the filtering section is provided with a limiting member for clamping with the closing plate to circumferentially limit the filter element rod. Adjacent two filter element rods are connected by threads.

[0010] Preferably, the limiting member includes a plurality of limiting rods arranged on the inner wall of the filtering section, and the circumferential side of the closing plate is provided with a limiting groove for the limiting rods to insert.

[0011] Preferably, one end of one of the filter element rods is provided with a threaded post, and the end of the other filter element rod is provided with a threaded sleeve for threaded connection with the threaded post.

[0012] Preferably, the end of the spare section is provided with a driving member for driving the filter element rod to translate.

[0013] Preferably, the driving member includes a threaded rod threadedly connected to the spare section, and a pressing block rotatably arranged at the end of the threaded rod and used for abutting against the closing plate.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. One of the filter element rods is located inside the heat dissipation pipe for filtering. When the filtering time is relatively long, generally one month, when the filter element rod needs to be replaced, by sliding the two filter element rods synchronously, the filter element rod located in the filtering section is moved into the spare section. At this time, the filter element rod on the other side is replaced, and then the previous filter element rod is disassembled and replaced. There is no need to pause the circulating heat dissipation device, which is relatively convenient.

[0016] 2. The cooperation of the limiting rods and the limiting grooves can enable the filter element rod located in the filtering section to maintain circumferential limitation when the filter element rod is disassembled. Description of the Drawings

Detailed Description of the Invention

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] A circulating heat dissipation device for a photovoltaic power station, referring to Figure 1 , includes a heat dissipation pipe 100 installed on one side of a photovoltaic panel. A filter box is arranged on the heat dissipation pipe 100, and the filter box is perpendicular to the heat dissipation pipe 100. The filter box includes a filtering section 110 located inside the heat dissipation pipe 100 and spare sections 111 arranged at both ends of the filtering section 110.

[0022] Referring to Figure 1 , Figure 2 , two detachably connected filter element rods are slidably arranged in the filter box in a positionable manner, and the filter element rods are of the same length as the filtering section 110. The filter element rod includes a core body 112, a central shaft 113 passing through the core body 112, and closing plates 114 arranged at both ends of the central shaft 113. The closing plates 114 are used to cooperate with the outer wall of the heat dissipation pipe 100 to achieve sealing. The closing plates 114 are circular, the heat dissipation pipe 100 is a square pipe, and the diameter of the closing plates 114 is greater than the inner wall height of the filtering section 110.

[0023] The filtering section 110 is provided with limiting members for clamping with the closing plates 114 to circumferentially limit the filter element rods, and adjacent two filter element rods are connected by threads. Specifically, the limiting members include a plurality of limiting rods 115 arranged on the inner wall of the filtering section 110. In this embodiment, there is one limiting rod 115 on both the upper and lower sides of the filtering section 110, and the limiting rods 115 are parallel to the length of the filter box. The circumferential side of the closing plates 114 is provided with limiting grooves 116 for the limiting rods 115 to insert into.

[0024] One end of one of the filter element rods is provided with a threaded column 117, and the end of the other filter element rod is provided with a threaded sleeve 118 for threaded connection with the threaded column 117. A driving member for driving the filter element rods to move synchronously in parallel is arranged at the end of the spare section 111. In this example, the driving member is a threaded rod 120 threadedly connected to the end of the spare section 111 and a pressing block 121 connected to the end of the threaded rod 120. The pressing block 121 is rotatably connected to the end of the threaded rod 120 through a bearing. When rotating, it can press on the closing plate 114 to move the filter element rods, and during the moving process, at least part of the limiting rods 115 cooperate with the limiting grooves 116 for guiding.

[0025] When the threaded rod 120 rotates to the end, it just makes the new filter element rod completely located inside the filtering section 110. It should be noted that before rotation, the threaded rod 120 on the other side needs to be completely unscrewed. After replacing the position, the spare section 111 is opened. A hexagonal hole is provided on the exposed closing plate 114, and the replaced filter element rod can be rotated through a tool, so that the threaded sleeve 118 and the threaded column 117 will be separated, and at this time, the filter element rod located inside the filtering section 110 will be circumferentially limited by the limiting rods 115, which is very convenient.

[0026] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
