Description

Technical Field

[0001] This utility model relates to the field of solar collector cleaning technology, and more specifically, to a manual solar collector cleaning device. Background Technology

[0002] Parabolic trough collectors are widely used in the field of solar energy utilization as key equipment for converting solar radiation energy into heat energy. However, during long-term use, dust, dirt, scale and other impurities easily accumulate on the surface and internal pipes of the collectors. The presence of these impurities seriously affects the collectors' absorption and conversion efficiency of solar energy, leading to a decline in collector performance and thus reducing the efficiency of the entire solar energy utilization system.

[0003] Currently, the cleaning of solar collectors is partly done manually using simple hand tools. This method has many drawbacks, such as low cleaning efficiency, difficulty in thoroughly cleaning all parts of the collector, especially the internal pipes, and significant safety risks associated with manual cleaning in high-altitude or complex installation environments. In addition, while some automated cleaning equipment can improve cleaning efficiency, it is complex in structure and expensive, making it unsuitable for small solar systems or users with limited financial resources.

[0004] Therefore, in view of the above situation, this utility model proposes a manual cleaning device for solar collectors. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a manual cleaning device for solar collectors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manual cleaning device for solar collectors, including a liquid storage tank, a cleaning rod assembly on one side of the liquid storage tank, a cleaning liquid delivery assembly inside the cleaning rod assembly, and a brush head assembly detachably installed at one end of the cleaning rod assembly.

[0007] As can be seen, this structure stores cleaning fluid in a storage tank, extends operation by relying on the cleaning rod assembly, and delivers the cleaning fluid to the detachable brush head assembly through the internal cleaning fluid delivery assembly, thereby realizing the cleaning operation of the solar collector components.

[0008] Preferably, the cleaning rod assembly is a telescopic structure consisting of several hollow rods connected together, and each hollow rod has a through-hole that is interconnected with a locking hole, the inside of which is threaded with a locking bolt.

[0009] This structure is designed to accommodate the cleaning needs of solar collectors at different installation positions and heights by adjusting the length of the hollow rod through telescopic movement and securing it with locking bolts.

[0010] Preferably, the cleaning fluid delivery structure includes a miniature pump fixed inside the hollow rod at the far right end. The input end of the miniature pump is provided with a delivery hose connected to the storage tank. A control valve is installed on the delivery hose. The output end of the miniature pump is provided with a connecting pipe located inside several hollow rods. One end of the connecting pipe extends to the hollow rod at the left end.

[0011] In order to provide power through a micro pump, the structure draws cleaning fluid from the storage tank through a delivery hose and delivers it to the hollow rod at the left end through a connecting pipe. At the same time, the flow rate is regulated by a control valve to achieve directional or controllable delivery of cleaning fluid to the brush head assembly, thus meeting the cleaning fluid supply requirements.

[0012] Preferably, the brush head assembly includes, but is not limited to, several cleaning brush heads for cleaning different structures of the solar collector. The surface of the cleaning brush head is connected to a connecting pipe, one end of which is threadedly and sealed to a connecting pipe. An internal threaded ring is fixedly installed on the outer wall of the cleaning brush head, and the internal threaded ring is threadedly connected to the outer wall of the hollow rod at the leftmost end.

[0013] This structure allows for easy disassembly and secure fixing of different cleaning brush heads, enabling flexible selection of appropriate cleaning brush heads based on the different structures of the solar collector. This ensures that the cleaning fluid is smoothly delivered to the brush head, improving the cleaning effect on all parts of the solar collector.

[0014] Preferably, a handle is installed on the outside of the hollow rod located at the rightmost end, and a battery assembly is installed on the outside of the handle, the battery assembly being electrically connected to the micro pump.

[0015] This structure provides operators with a stable grip via a handle, facilitating the adjustment of the cleaning rod assembly in terms of cleaning position and angle. Furthermore, a battery assembly provides the necessary power to the micro-pump, ensuring the extraction and delivery of the cleaning fluid.

[0016] Preferably, the surface of the liquid storage tank is provided with a liquid inlet pipe, and a sealing plug is threaded onto the liquid inlet pipe, and a handle is movably installed on the outer wall of the liquid storage tank.

[0017] This structure allows for convenient injection of cleaning fluid into the storage tank via the inlet pipe. A sealing plug is used to seal the inlet pipe, preventing leakage of cleaning fluid or the entry of external impurities. At the same time, a movable handle facilitates the handling and carrying of the storage tank by the operator.

[0018] The technical effects and advantages of this utility model are as follows: 1. By setting up a telescopic cleaning rod assembly consisting of several hollow rods connected together with locking holes and locking bolts, and a brush head assembly containing a variety of compatible brush heads and disassembly and assembly through threaded sealing connection, the equipment can flexibly adjust the length of the cleaning rod to adapt to collectors with different installation heights and positions, and can also select the corresponding brush head according to the structure of the part to be cleaned, significantly improving the adaptability and comprehensiveness of collector cleaning. 2. By setting up a cleaning fluid delivery structure and a battery assembly electrically connected to the micro pump, the micro pump can provide stable power to deliver the cleaning fluid to the brush head through the delivery channel. The flow rate can be adjusted as needed by the control valve to avoid waste of cleaning fluid and ensure cleaning power. On the other hand, the battery assembly provides independent power without the need for an external power source. The overall equipment is simple to operate and convenient for operators to use.

[0032] Specifically, in this structure, a suitable cleaning brush head 9 is selected according to different cleaning positions of the solar collector. In this embodiment, a roller cleaning brush head 9 can be selected to clean the surface of the solar collector. The connecting pipe 10, which is connected to the cleaning brush head 9, is threaded to one end of the connecting pipe 8, and the inner threaded ring 11 on the outer wall of the cleaning brush head 9 is threaded to the hollow rod 2 on the left end, thus realizing the installation of the cleaning brush head 9. The cleaning fluid inside the connecting pipe 8 can be delivered to the connecting pipe 10 and delivered to the surface of the cleaning brush head 9, so that the designated part of the solar collector can be cleaned through the cleaning brush head 9.

[0033] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figure 3, a handle 12 is installed on the outside of the hollow rod 2 located at the far right end, and a battery assembly 13 is installed on the outside of the handle 12.

[0036] Specifically, in this structure, the inlet pipe 14 allows the operator to pour the cleaning fluid into the inside of the storage tank 1 and seal it with the sealing plug 15, while the handle 16 allows the operator to move and carry the storage tank 1.

[0037] Example 2 As attached Figure 2 As shown, the difference between this embodiment and embodiment 1 is that a cylindrical brush head assembly is selected and installed according to different cleaning positions of the solar collector. The outer diameter of the cylindrical brush head assembly is adapted to the inner wall of the pipe of the solar collector, thereby cleaning the pipe of the solar collector. All other structures are the same as those in embodiment 1.

[0038] Example 3 As attached Figure 3 As shown, the difference between this embodiment and embodiment 1 is that a disc-shaped brush head assembly is selected for installation, which can perform cleaning operations on small parts of the solar collector. All other structures are the same as in embodiment 1.

[0039] It is worth noting that in the above embodiments, the operator selects to install brush head assemblies with different structures according to the different cleaning parts of the solar collector and the dust situation, and the shape and structure of the brush head assembly are not specifically limited in this application.

[0040] The principles of this application will be explained in detail below: This application provides a manual cleaning device for solar collectors. In actual use, the operator first injects a suitable cleaning solution through the liquid inlet pipe 14 on the surface of the liquid storage tank 1. After the injection is completed, the sealing plug 15 is threaded onto the liquid inlet pipe 14 to achieve a seal. The liquid storage tank 1 is then moved by means of the handle 16 that is movably installed on the outer wall. Next, select different brush head assemblies for installation based on the specific cleaning part of the solar collector. After determining the brush head, connect the connecting pipe 10 on the surface of the cleaning brush head 9 to one end of the connecting pipe 8 in the cleaning rod assembly with a threaded seal. At the same time, connect the inner threaded ring 11 on the outer wall of the cleaning brush head 9 to the outer wall of the leftmost hollow rod 2 with a threaded connection to complete the stable installation of the brush head assembly and ensure the sealing of the cleaning fluid delivery channel. Operators can stretch or shrink the hollow rod 2 according to actual needs. After the length is adjusted to the appropriate size, the locking bolt 4 is threaded into the locking holes 3 that are interconnected on the surface of several hollow rods 2 to fix the hollow rod 2 after adjustment and ensure the stability of the cleaning rod assembly during the cleaning operation. The operator holds the handle 12 on the outside of the rightmost hollow rod 2. After the micro pump 5 is powered on, it starts to work. At this time, the operator can manually adjust the control valve 7 on the delivery hose 6 to control the flow rate of the cleaning fluid according to the severity of the fouling of the collector and the cleaning needs. The micro pump 5 draws the cleaning fluid from the storage tank 1 through the delivery hose 6 at the input end. The drawn cleaning fluid is delivered to the left hollow rod 2 through the connecting pipe 8 at the output end of the micro pump 5, and then delivered to the surface of the cleaning brush head 9 through the connecting pipe 10. Finally, the operator drives the cleaning rod assembly and the brush head assembly by operating the handle 12, and uses the brush head with cleaning fluid to clean the designated parts of the collector until the cleaning operation of the entire collector is completed.
