[0002] A photothermal converter is a device or system that converts sunlight into heat. One of the most common photothermal converters is a solar water heater. A solar water heater absorbs sunlight and converts it into heat using a photothermal converter (such as a solar collector) to heat water. This conversion process can provide a hot water supply and reduce the need for traditional energy sources.
[0003] Existing solar thermal converters are mostly placed on roofs during actual use, with their surfaces exposed to the outside to absorb heat. However, when used for a long time, in some dusty places, their surfaces will be covered with dust, which will affect the absorption of sunlight and its conversion into heat energy. In addition, the roofs are high and many are tilted, so manual cleaning by personnel is dangerous. Utility Model Content

DETAILED DESCRIPTION
[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a photothermal converter with heat insulation material, including a fixed frame 1, a storage box 2 is fixed on the surface of the fixed frame 1, a bottom plate 3 is fixed on the surface of the fixed frame 1, a photothermal converter 4 is fixed on the surface of the bottom plate 3, and the end of the photothermal converter 4 away from the bottom plate 3 is fixed to the storage box 2 and communicated with each other, and a cleaning component 5 is arranged on the surface of the fixed frame 1, and the cleaning component 5 includes: a limit plate 50, a base 51, a motor 52, a gear 53, a rack 54, a sliding rod 55, a connecting plate 56, a fixing column 57, a fixing rod 59, a stabilizing plate 500, and a through hole 501.
[0021] The limiting plate 50 is fixed on the surface of the fixing frame 1, and the bottom of the limiting plate 50 is rotatably connected with a gear 53, and the bottom of the limiting plate 50 is slidably connected with a rack 54, which meshes with the gear 53, and a sliding rod 55 is fixed to the bottom of the rack 54, and a fixing column 57 is attached to the inner side of the sliding rod 55, and a connecting plate 56 is fixed to the bottom of the fixing column 57. A motor 52 is arranged below the limiting plate 50, and a base 51 is fixed to the bottom of the motor 52, and the output shaft of the motor 52 is fixed to the bottom of the connecting plate 56. A fixing rod 59 is fixed to the top of the rack 54, and the top of the fixing rod 59 passes through the limiting plate 50, and the fixing rod 59 is slidably connected to the limiting plate 50, and a stabilizing plate 500 is fixed to the top of the fixing rod 59, which stabilizes the fixing plate 500. A through hole 501 is provided on the surface of the fixed plate 500, and the photothermal converter 4 passes through the through hole 501. When the motor 52 is turned on, the connecting plate 56 drives the fixed column 57 to rotate synchronously, and the surface of the fixed column 57 contacts the sliding rod 55 to move, driving the rack 54 and the fixed rod 59 to move synchronously. At this time, the fixed rod 59 drives the stabilizing plate 500 to move linearly, so that the brush cleans the surface of the photothermal converter 4. At the same time, when the rack 54 moves, it drives the gear 53 to rotate, so that the two groups of racks 54 perform simultaneous staggered movement. Through the sliding rod 55 and the fixed column 57, when the motor 52 continues to work, the two groups of racks 54 can be made to reciprocate in a linear alignment motion, so that the brush can reciprocate to clean the photothermal converter 4.
[0022] A brush is fixed on the inner side of the through hole 501, and the end of the brush away from the through hole 501 is in contact with the surface of the photothermal converter 4, which is convenient for cleaning the photothermal converter 4. A connecting rod 6 is fixed to the bottom of the stabilizing plate 500, and the bottom of the connecting rod 6 is slidably connected to the top of the limiting plate 50, thereby increasing the stability of the movement of the stabilizing plate 500.
[0023] There are two groups of racks 54, fixed rods 59 and stabilizing plates 500, and the two groups of racks 54, fixed rods 59 and stabilizing plates 500 are arranged in a circular array with the center of the gear 53 as the axis, so that when the motor 52 continues to work, the gear 53 can be used to make the two groups of racks 54, fixed rods 59 and stabilizing plates 500 reciprocate relative to each other in a straight line. The fixed column 57 is set to a cylindrical shape to avoid motion interference when the motor 52 moves. The slide bar 55 is fixed at the bottom of one of the two groups of racks 54, and when the slide bar 55 moves, it can drive the racks 54 to move, and through the gear 53, the other group of racks 54 can be moved.
[0024] In use, the photothermal converter 4 absorbs heat from the sun to heat the water, and stores it in the storage box 2. When used for a long time, the surface of the photothermal converter 4 is covered with dust. At this time, the personnel can turn on the motor 52. At this time, the output shaft of the motor 52 will drive the connecting plate 56 to rotate, thereby driving the fixed column 57 to rotate synchronously. At this time, the surface of the fixed column 57 contacts the sliding rod 55 to move, driving the rack 54 and the fixed rod 59 to move synchronously. At this time, the fixed rod 59 drives the stabilizing plate 500 to move in a straight line, so that the brush cleans the surface of the photothermal converter 4. At the same time, when the rack 54 moves, it drives the gear 53 to rotate. The two sets of racks 54 can make simultaneous staggered movements, and through the sliding rod 55 and the fixed column 57, when the motor 52 continues to work, the two sets of racks 54 can make reciprocating linear centering movements, so that the brush can reciprocate to clean the photothermal converter 4, without the need for manual cleaning by personnel, to avoid dust coverage affecting normal use. At the same time, when the stabilizing plate 500 moves, it will drive the connecting rod 6 to move. The connecting rod 6 can maintain the stability of the movement of the stabilizing plate 500 when it moves. The limit plate 50 is set to a polyurethane foam material, which can effectively insulate and avoid cracking caused by long-term exposure to the sun that affects the normal use of the device.
[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
