[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0019] like Figure 1 — Figure 7As shown, a cleaning device for a dish-type solar thermal hydrogen production equipment includes a concentrator 1, a cleaning component at the center of the concentrator 1, a drive motor 5 at the rear end of the concentrator 1, and a rotating disk 2. The drive motor 5 is driven by the rotating disk 2. A self-rotation drive component is installed inside the rotating disk 2, and several roller brush components 3 are mounted on the rotating disk 2. The roller brush components 3 are connected to the self-rotation drive component through the rotating disk 2. The roller brush components 3 have brush heads 304 passing through the rotating disk 2 and are located on the concentrating end face of the concentrator 1. When in use, the drive motor 5 starts, and its output end drives the rotating disk 2 to revolve around the central axis of the concentrator 1 through a rotating shaft 501. At this time, the roller brush components 3... The bevel gear 301 meshes with the bevel gear ring 6 fixed inside the rotating disk 2, causing the bevel gear 301 to rotate and drive the brush head 304 to rotate via the transmission shaft 302. During the revolution, the rotating disk 2 drives the brush head 304 to pass through the focusing end faces of several reflector discs 101 of the concentrator 1 for cleaning. During this process, the rotation of the brush head 304 can efficiently wipe the dust and stains on the surface of the reflector discs 101. During the cleaning process, the drive motor 5 drives the cleaning components to run for a long time. Through repeated friction and rolling action, it can effectively remove fine particles, sand, water stains and other pollutants attached to the end face of the reflector discs 101, significantly improving the cleaning effect and cleaning efficiency.
[0020] The brush head 304 is densely packed with bristles along its axis. As the brush head 304 rotates, the bristles sweep and contact the focusing end face of the reflector disc 101, effectively removing fine particles, dust, water stains and other contaminants attached to the focusing end face, thus preventing impurities from interfering with the focusing.
[0021] Furthermore, the concentrator 1 also includes a support base 4 and several reflective discs 101, which are equidistantly distributed around the rotating disk 2. A fixing frame 401 is installed at one end of the support base 4, and a support bone 402 is connected to the side of the reflective disc 101 away from its concentrating end face. The other end of the support bone 402 is connected to the fixing frame 401. By designing the reflective discs 101 to be equidistantly distributed around the rotating disk 2, each reflective disc 101 can be evenly and completely covered when the rotating disk 2 drives the brush head 304 to revolve, avoiding cleaning dead corners. The support base 4 is fixedly connected to the reflective discs 101 through the fixing frame 401, so that the reflective discs 101 will not shake or shift. The support base 4 is also connected to a reactor, so that the light and heat reflected by the reflective discs 101 are focused on the reflector to react. There are gaps between the reflective discs 101, which facilitates the passage of debris and prevents debris from accumulating on the concentrator 1 after cleaning and affecting the concentrating effect.
[0022] Furthermore, the brush head 304 extends outward along the radial direction of the reflector disc 101, and the cross-section of the brush head 304 is parallel to that of the reflector disc 101. During use, this ensures that the brush head 304 can closely fit the curved surface of the reflector disc 101, achieving cleaning without dead angles.
[0023] Furthermore, the rotating disk 2 includes a flange 201 and a cage 202. The output end of the drive motor 5 is driven to connect to a rotating shaft 501, and is driven to connect to the flange 201 through the rotating shaft 501. The flange 201 is fixedly connected to the cage 202. The self-rotation drive assembly is disposed inside the cage 202. Several roller sweeping assemblies 3 are equidistantly disposed on the side wall of the cage 202, and the several roller sweeping assemblies 3 are driven to connect to the self-rotation drive assembly.
[0024] Furthermore, the self-rotating drive assembly includes a bevel gear ring 6 fixedly disposed inside the retainer 202, the bevel gear ring 6 being coaxial with the retainer 202, and the roller brush assembly 3 including a bevel gear 301 disposed inside the retainer 202 and meshing with the bevel gear ring 6, the other end of the bevel gear 301 being provided with a drive shaft 302, the drive shaft 302 passing through the side wall of the retainer 202 and being connected to the brush head 304 for transmission.
[0025] Furthermore, the bevel gear ring 6 is fixedly connected to the fixed frame 401, and the rotating shaft 501 passes through the fixed frame 401 and the bevel gear ring 6 and is driven to connect to the flange 201. A first bearing 7 is provided between the rotating shaft 501 and the fixed frame 401 to provide radial support for the rotating shaft 501, ensuring the stability of the rotating shaft 501 during rotation and preventing the rotation accuracy of the rotating disk 2 from being affected by the shaking of the rotating shaft 501. This allows the brush head 304 to cover the focusing end face of the reflector disc 101 by rotation, ensuring the uniformity of cleaning.
[0026] Furthermore, a second bearing 8 is fitted on the outside of the fixed frame 401, and a sealing cover 203 is rotatably connected to the second bearing 8. The sealing cover 203 is fixedly connected to the retainer 202. During use, the sealing cover 203 rotates synchronously with the retainer 202, effectively preventing external dust, moisture and other impurities from entering the interior of the retainer 202, thus avoiding corrosion of the transmission components of the self-rotation drive assembly and the roller sweeping assembly 3.
[0027] Furthermore, a universal joint 303 connects the drive shaft 302 and the brush head 304. During use, the connection end between the brush head 304 and the drive shaft 302 can adapt to the installation angle of the reflector disc 101 and can stably transmit power, so that the brush head 304 always maintains good contact with the focusing end face of the reflector disc 101, thereby helping to ensure the cleaning effect.
[0028] Furthermore, the drive motor 5 is installed on the other axial end of the support base 4 away from the fixed frame 401. During use, it provides stable support for the drive motor 5, while avoiding the drive motor 5 from blocking or interfering with the focusing effect of the concentrator 1. It also facilitates the installation, maintenance and heat dissipation of the motor, ensuring its long-term stable operation.
[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
