Description

Technical Field

[0001] This utility model relates to the field of solar energy technology, and in particular to a cleaning device. Background Technology

[0002] In a tower solar thermal system, the receiver is responsible for absorbing solar energy. Generally, the receiver has a polygonal prism structure, comprising multiple absorber tube panels. Each absorber tube panel consists of a series of metal absorber tubes arranged side-by-side. The two ends of each absorber tube are connected to a corresponding header. The header is equipped with a thermal protection component to prevent damage from the high temperatures generated by sunlight reflected from the heliostat field in the tower solar thermal system. Because tower solar thermal systems are typically built in deserts, Gobi, or other areas with high wind and sand, dust easily accumulates on the receiver surface. This dust forms an insulating layer on the surface of the absorber tube panels, preventing them from effectively absorbing solar energy and thus reducing the receiver's heat absorption efficiency.

[0003] Meanwhile, since dust accumulation reduces the heat absorption efficiency of the absorber, in order to make the tower solar thermal utilization system reach the set operating parameters, it is necessary to extend the heat absorption time of the absorber or increase the amount of solar energy projected onto the absorber by the heliostat field. Long-term accumulation will have an adverse effect on the performance of the absorber, such as causing thermal fatigue of the material and shortening the service life of the absorber.

[0036] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0037] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0038] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0039] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation.

Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0040] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0041] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts.

[0043] like Figures 1 to 7 As shown, this embodiment provides a cleaning device for cleaning a heat absorber 1000. A support member 2000 is disposed below the heat absorber 1000. The heat absorber 1000 has a polygonal prism structure and includes multiple heat-absorbing tube panels 1100. Each heat-absorbing tube panel 1100 is composed of a series of metal heat-absorbing tubes arranged side by side. Both ends of the heat-absorbing tube panel 1100 are connected to corresponding headers, and a thermal protection component 1200 is disposed on the outside of the headers. In this embodiment, the cleaning process of the heat absorber 1000 requires cleaning multiple heat-absorbing tube panels 1100 sequentially.

[0044] The cleaning device includes a guide assembly 100, a cleaning assembly 200, and a drive assembly 300. The guide assembly 100 includes a suspension member 110 and a guide member 120. One end of the suspension member 110 is located at the top of the absorber 1000, and the other end extends to the outside of the absorber 1000 and connects to the upper end of the guide member 120. The lower end of the guide member 120 is connected to a support member 2000. The guide member 120 is spaced apart from the absorber 1000. The cleaning assembly 200 includes a cleaning member 210, which is used to clean the outer wall of the absorber 1000. The cleaning member 210 has a guide portion that cooperates with the guide member 120 and can move up and down along the guide member 120. The drive assembly 300 is located at the top of the absorber 1000, and its output end is connected to the cleaning member 210.

[0045] The cleaning component 210 in the above-mentioned configuration can clean the outer wall of the heat absorber 1000 during the lifting and lowering process along the guide 120, thereby removing accumulated dust, which helps to improve the heat absorption efficiency of the heat absorber 1000 and ensure the service life of the heat absorber 1000. At the same time, the suspension component 110 allows the entire guide 120 to be kept away from the heat absorber 1000, thus guiding the cleaning component 210 while avoiding collisions or even scratches to the heat absorber 1000. Finally, the automatic cleaning function of the cleaning device is realized by driving the cleaning component 210 through the drive assembly 300, which improves the cleaning efficiency and reduces labor intensity.

[0046] In some embodiments, the guide assembly 100 further includes a first fixing member 130 and a second fixing member 140. The first fixing member 130 is connected to one end of the suspension member 110 extending to the outside of the heat absorber 1000, and the second fixing member 140 is fixed to the support member 2000 that supports the heat absorber 1000. The guide member 120 includes a plurality of guide ropes arranged parallel to each other, taut, and connected between the first fixing member 130 and the second fixing member 140. The guide portion includes a plurality of guide channels provided in the cleaning member 210, and the plurality of guide ropes are correspondingly threaded through the plurality of guide channels. By fixing the guide ropes with the first fixing member 130 and the second fixing member 140, the guide ropes form a straight structure, thereby playing a better guiding role and preventing the cleaning member 210 from swaying and shaking during the lifting and lowering process. For example, there are two guide ropes. The arrangement of the two guide ropes can restrain the swaying of the cleaning member 210 in the horizontal direction and prevent rotational movement.

[0047] To ensure the guide rope remains taut, in some embodiments, combined with Figure 2 and Figure 3 As shown, the suspension component 110 is a tower crane. The first fixing component 130 has two first lifting lugs 131 and two fixing parts 132 spaced apart along its length. The two first lifting lugs 131 are located outside the two fixing parts 132 (that is, in the horizontal direction, the distance between the two first lifting lugs 131 and the heat absorber 1000 is greater than the distance between the two fixing parts 132 and the heat absorber 1000). A first rope 1311 is connected between the two first lifting lugs 131. The output end of the second rope 111 of the tower crane is connected to the middle part of the first rope 1311. The guide assembly 100 also includes two fixed connecting rods 150. The two fixed connecting rods 150 are arranged in parallel and are connected between the two fixing parts 132 and the top of the heat absorber 1000. The tower crane can raise and lower the first fixed member 130 by winding and releasing the second rope 111 through its hoisting function. When the first fixed member 130 is raised, it moves away from the second fixed member 140, thus tautning the guide rope; when the first fixed member 130 is lowered, it moves closer to the second fixed member 140, thus facilitating the connection of the guide rope. Specifically, the top steel structure of the heat absorber 1000 is provided with lugs, one end of the fixing rod 150 is hinged to the lugs, and the other end is hinged to the fixing part 132, so as to accommodate the raising and lowering of the first fixed member 130 and prevent it from deflecting or swaying.

[0048] Considering that the absorber 1000 has a polygonal prism structure, in order to clean the absorber tube panels 1100 on other surfaces, in some embodiments, a tower crane is rotatably mounted on top of the absorber 1000, and the guide assembly 100 has several second fixing members 140, which are spaced apart around the axis of the absorber 1000. Each absorber tube panel 1100 corresponds to two second fixing members 140. This arrangement allows the guide rope and second fixing members 140 to be disassembled after cleaning one absorber tube panel 1100, and then the tower crane can be rotated so that the guide rope is outside another absorber tube panel 1100 before being fixed back to the corresponding second fixing member 140. In other embodiments, multiple cleaning members 210 can be set simultaneously to correspond to multiple absorber tube panels 1100 respectively, and cleaning can be completed by raising and lowering the multiple cleaning members 210 respectively to each of the multiple absorber tube panels 1100.

[0049] Regarding the connection between the guide rope and the first fixing member 130, in some embodiments, the first fixing member 130 is provided with a plurality of second lifting lugs 133 spaced apart along its own length direction. Each of the second lifting lugs 133 corresponds to a plurality of guide ropes, with the upper end of each guide rope fixed to one of the second lifting lugs 133. Specifically, the first fixing member 130 is provided with two second lifting lugs 133 spaced apart along its own length direction, and the upper ends of the two guide ropes are correspondingly fixed to the two second lifting lugs 133. This arrangement provides position guidance for the installation of the guide ropes, and connecting the guide ropes to the second lifting lugs 133 ensures the relative position of the guide ropes and the first fixing member 130. Along the extension direction of the first fixing member 130, it prevents the guide ropes and the first fixing member 130 from sliding relative to each other, thereby providing reliable guidance for the cleaning component 210.

[0050] Regarding the connection between the guide rope and the second fixing member 140, in some embodiments, combined with Figure 5 As shown, the guide assembly 100 also includes a guide joint 160, with the guide rope connected to the lifting ring 162 of the guide joint 160. One of the second fixing member 140 and the guide joint 160 is provided with a screw 161, and the other with a screw sleeve. The second fixing member 140 and the guide joint 160 are screwed together. This arrangement improves the connection speed, thereby facilitating the cleaning member 210 in cleaning multiple heat-absorbing tube screens 1100 and improving overall cleaning efficiency. Specifically, in this embodiment, the second fixing member 140 is provided with a screw sleeve, the guide joint 160 is provided with a screw 161, the lifting ring 162 is located at the upper end of the screw 161, and the guide rope is connected to the lifting ring 162.

[0051] For example, a threaded sleeve is provided on the second fixing member 140. When needed, the screw 161 of the guide joint 160 is screwed into the threaded sleeve. When the cleaning member 210 needs to change angle, the guide joint 160 needs to be separated from the second fixing member 140. To prevent impurities from entering the threaded sleeve, in some embodiments, the carrier member 2000 is provided with a connecting groove. Part of the second fixing member 140 is embedded below the connecting groove, and part of it is located in the connecting groove. The guide assembly 100 also includes a sealing member, which selectively seals the connecting groove. The sealing member can seal the connecting groove, thereby blocking the second fixing member 140 and preventing impurities from falling into the threaded sleeve for subsequent use. The sealing member can be a columnar structure with an annular connecting portion at the top. The carrier member 2000 is a conversion platform.

[0052] In some embodiments, combined with Figure 6 and Figure 7 As shown, the cleaning component 210 includes a cleaning cylinder with an internal cavity, an air inlet 211 communicating with the internal cavity, and several air outlets 212. The air inlet 211 is connected to an external air source, and the air outlets 212 are evenly distributed along the axial direction of the cleaning cylinder. Sealing heads are placed at both ends of the cleaning cylinder. In use, an external air source is connected to the air inlet 211 via a pipeline, and the air outlets 212 purge the heat absorber tube screen 1100. The pipeline is wound around the top of the heat absorber 1000 and can be rolled out or rewound to accommodate different positions of the cleaning component 210. In this embodiment, the cleaning assembly 200 also includes a guide tube 220. The internal channel of the guide tube 220 forms a guide channel, and two guide tubes 220 are respectively connected to both ends of the cleaning cylinder or spaced apart on the outside of the cleaning cylinder. Specifically, the guide tubes 220 are welded to the cleaning cylinder. In other embodiments, the guide channel can be directly formed on the cleaning component 210.

[0053] In other embodiments, the cleaning component 210 includes a brush for generating friction with the heat-absorbing tube screen 1100. The cleaning component 210 also includes a cleaning seat, to which the brush is fixed. The cleaning seat is slidably mounted on a guide rope via a guide tube 220, and the brush generates friction with the heat-absorbing tube screen 1100 during the raising and lowering of the cleaning seat. Furthermore, the brush is rotatably mounted on the cleaning seat and driven by a drive component to improve the cleaning effect.

[0054] To drive the cleaning component 210, in some embodiments, the drive assembly 300 includes a decelerator 310, which is located on top of the absorber 1000 and has its output end connected to the cleaning component 210. The decelerator 310 is detachably mounted on the steel structure on top of the absorber 1000. The structure and working principle of the decelerator 310 are well known to those skilled in the art and will not be described in detail here.

[0055] In some embodiments, combined with Figure 2and Figure 4 As shown, the guide assembly 100 includes a first fixing member 130, a guide member 120 disposed on the first fixing member 130, a fixed pulley 134 provided on the first fixing member 130, and a third rope 320 on the descent device 310 passing over the fixed pulley 134 and connected to a third lifting lug 213 on the cleaning member 210. This arrangement causes rolling friction between the third rope 320 and the fixed pulley 134, improving the service life of the third rope 320 and avoiding wear on the heat absorber 1000. There are two descent devices 310 and two third ropes 320, each passing over a corresponding fixed pulley 134 and connected to a corresponding third lifting lug 213.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
