DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0028] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0029] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0031] Passivated contact cells are a type of solar cell technology based on tunnel oxide passivated contacts. During the cell manufacturing process, a cleaning device is required to clean silicon wafers or cell wafers. The drain pipe of the cleaning device is often exposed outside the equipment, which makes it easy for workers to accidentally step on the drain pipe when entering the area for maintenance work. This careless stepping not only causes the drain pipe to bend and deform, but may also cause the drain pipe to loosen and deform, thereby causing chemical leakage.

[0032] In order to prevent this from happening, it is necessary to design a cover assembly for protecting the drain pipe. The cover assembly should have the function of effectively protecting the drain pipe. However, by designing the cover assembly on the drain pipe, there may be problems with inconvenient assembly and disassembly, thereby affecting the efficiency of installation, maintenance and disassembly. In order to meet the needs of protecting the cover assembly and rapid on-site maintenance at the same time, the cover assembly should also have a structure that is convenient and quick to disassemble and assemble to reduce the downtime during equipment maintenance. In addition, in order to prevent staff from accidentally stepping on the cover and falling, the cover assembly should also have the function of limiting horizontal displacement. Based on this, an embodiment of the present application provides a cover assembly and a cleaning device.

[0033] Figure 1 and Figure 2 The structure schematic diagram of the cover assembly 1 provided in the embodiment of the present application is shown, which includes a first cover 10, a second cover 20, a first connector 30 and a second connector 40. The first cover 10 includes a first receiving groove 103 with an opening; the second cover 20 includes a second receiving groove 203 with an opening; the first connector 30 is arranged at the end of the first cover 10 along the first direction; the second connector 40 is arranged at the end of the second cover 20 along the first direction, and the second connector 40 can form an embedded connection with the first connector 30 to connect the first cover 10 and the second cover 20 and connect the first receiving groove 103 and the second receiving groove 203, and the first cover 10 and the second cover 20 are mutually limited along the first direction; the second connector 40 can also be separated from the first connector 30 along the second direction perpendicular to the first direction to separate the first cover 10 and the second cover 20.

[0034] In this embodiment, the first cover body 10 includes a first accommodating groove 103 with an opening. When the first cover body 10 is installed in the use scenario, the opening is arranged toward the installation surface (which can be the ground), and the first accommodating groove 103 is used to accommodate the drain pipe to protect the drain pipe. The first cover body 10 can have a strong structural strength so as to support the staff to step on the first cover body 10. At the same time, since the cleaning device may inevitably need to be used in an acid-base environment, in order to avoid the first cover body 10 being corroded in the acid-base environment to reduce the structural strength, the first cover body 10 can be made of corrosion-resistant plastic plate, such as: PAF plastic (English name: Polyfluoroalkoxy, Chinese name: soluble polytetrafluoroethylene), so that the first cover body 10 has corrosion-resistant properties. The length of the first cover body 10 can be cut as needed according to the laying of the drain pipe.

[0035] It can be understood that since the length of the drain pipe is relatively long and it may not always extend in the same direction, it is necessary to use multiple sections of cover bodies to splice to fully cover and protect the drain pipe. Therefore, the cover body assembly 1 of the embodiment of the present application also includes a second cover body 20, and the second cover body 20 is also a second receiving groove 203 with an opening. When the second cover body 20 is installed in the use scenario, the opening is set toward the installation surface. The second receiving groove 203 is used to accommodate the drain pipe to protect the drain pipe. Like the first cover body 10, the second cover body 20 can also be made of PAF plastic.

[0036] In addition to acid and alkaline environments, the cover assembly 1 can also be used in outdoor environments, thereby preventing the drain pipe from being corroded by rainwater, snow water and other pollutants, thereby ensuring the service life of the drain pipe.

[0037] It should be noted that the cover assembly 1 includes not only the first cover 10 and the second cover 20, but multiple groups of connected first cover 10 and second cover 20 can be provided according to actual needs on site. The embodiment of the present application only takes one group of the first cover 10 and the second cover 20 as an exemplary description.

[0038] The first cover body 10 and the second cover body 20 can be connected using the first connecting member 30 and the second connecting member 40, so that the first receiving groove 103 is connected to the second receiving groove 203, and the drain pipe can smoothly extend in the receiving space constructed by the first receiving groove 103 and the second receiving groove 203.

[0039] Specifically, for easy assembly, the first connector 30 can be disposed at the end of the first cover 10 along the first direction, and the second connector 40 can be disposed at the end of the second cover 20 along the first direction. The first direction can be horizontal or close to horizontal. Figure 1 The X-axis in shows the first direction.

[0040] In order to improve the overall service life of the cover body assembly 1, the first connecting member 30 and the second connecting member 40 can also be made of PAF plastic. The first connecting member 30 and the second connecting member 40 made of plastic material are not only suitable for acid and alkaline environments, but also easy to process the first connecting member 30 and the second connecting member 40 into different specifications and sizes to meet the connection requirements of cover body assemblies of different sizes and improve processing efficiency.

[0041] The second cover body 20 can be covered on the top of the drain pipe along the second direction, and form a connection relationship with the first cover body 10 during the covering process, wherein the second direction can be a vertical direction or close to the vertical direction. Figure 1 The Y-axis in shows the second direction.

[0042] Specifically, when the second cover body 20 is covered on the drain pipe from top to bottom, the second connecting member 40 forms an embedded relationship with the first connecting member 30 on the first cover body 10, and a limit is formed between the first connecting member 30 and the second connecting member 40 in the horizontal direction, so that the first cover body 10 and the second cover body 20 are limited to each other in the horizontal direction, and there will be no horizontal movement between the first cover body 10 and the second cover body 20. When the staff walks on the cover body assembly, they will not fall due to the movement of the first cover body 10 or the second cover body 20, thereby ensuring the safety of the staff's walking.

[0043] In the case where the drain pipe needs to be inspected and repaired, the staff only needs to lift the second cover body 20 upwards along the second direction to release the embedding relationship between the first connecting member 30 and the second connecting member 40, so that the first connecting member 30 and the second connecting member 40 can be separated, thereby separating the second cover body 20 and the first cover body 10, thereby removing the cover body assembly 1 in whole or in part from above the drain pipe, thereby facilitating the inspection and repair of the drain pipe.

[0044] It can be seen that the installation and separation process of the first cover body 10 and the second cover body 20 are very simple and quick. The staff only needs to align the second connecting member 40 with the first connecting member 30 in the vertical direction and then move the second cover body 20 downward to simultaneously complete the two operations of buckling the second cover body 20 on the drain pipe and forming an embedded connection between the second connecting member 40 and the first connecting member 30. When the drain pipe needs to be repaired or the cover body assembly 1 needs to be replaced, the cover body assembly 1 can be removed by simply lifting the second cover body 20 upward, thereby meeting the needs of quick installation and quick removal on site and improving the work efficiency of installation and maintenance.

[0045] In this way, the cover assembly 1 provided in the embodiment of the present application can be placed on top of the drain pipe to protect the drain pipe. When the staff enters the drainage pipe laying area, they can walk on the cover assembly 1 to ensure the smooth progress of the staff's maintenance work. By respectively arranging the first connector 30 and the second connector 40 on the first cover 10 and the second cover 20, an embedded relationship can be formed between the first connector 30 and the second connector 40, so that the first cover 10 and the second cover 20 can be mutually limited along the first direction to be stably connected to avoid movement and thus affect the safety of the staff's walking. In addition, in the case where the cover assembly 1 needs to be removed, this embedded relationship can be released by moving the second connector 40 along the second direction, thereby meeting the work requirements of rapid maintenance.

[0046] In another embodiment, one of the first connecting member 30 and the second connecting member 40 is formed with an avoidance groove 301, and the avoidance groove 301 is exposed to the first cover body 10 or the second cover body 20 along the first direction; the other of the first connecting member 30 and the second connecting member 40 is adapted to the avoidance groove 301 to form an embedded connection with the avoidance groove 301.

[0047] In this embodiment, a avoidance groove 301 is formed on one of the first connecting member 30 and the second connecting member 40, and the avoidance groove 301 can extend along the second direction. The notch of the avoidance groove 301 is connected to the outside, so as to facilitate the other of the first connecting member 30 and the second connecting member 40 to be inserted into the avoidance groove 301 along the second direction.

[0048] Furthermore, along the first direction, the avoidance groove 301 is exposed at the end of the first cover body 10 (when the avoidance groove 301 is set on the first connecting member 30) or the end of the second cover body 20 (when the avoidance groove 301 is set on the second connecting member 40), so as to facilitate the second connecting member 40 and the first connecting member 30 to form an embedded plug-in relationship through relative movement along the second direction.

[0049] The other one of the first connecting member 30 and the second connecting member 40 may also be constructed as a protrusion that matches the shape of the avoidance groove 301 . The shape of the protrusion may match the avoidance groove 301 , that is, the protrusion may be smoothly moved into or out of the avoidance groove 301 along the second direction.

[0050] For example, Figure 3 As shown, the first connecting member 30 may be provided with an avoidance groove 301, and the second connecting member 40 is constructed as a convex block. In this way, when the second connecting member 40 is covered on the drain pipe in the second direction along with the second cover body 20, since the avoidance groove 301 provided on the first connecting member 30 is exposed at the end of the first cover body 10, the notch of the avoidance groove 301 is connected to the upper surface of the first connecting member 30, that is, the surface away from the drain pipe, the second connecting member 40 can be directly inserted into the avoidance groove 301 along the second direction, so that an embedded connection relationship is formed between the first connecting member 30 and the second connecting member 40. The second connecting member 40 moves in the opposite direction along the second direction, and can be quickly separated from the first connecting member 30.

[0051] Exemplarily, the avoidance groove can also be provided on the second connecting member (not shown in the figure), the first connecting member is constructed as a protrusion, and the notch of the avoidance groove is connected to the lower surface of the second connecting member, that is, the surface of the second connecting member facing the drain pipe. Since the avoidance groove provided on the second connecting member is exposed at the end of the second cover body, when the second cover body drives the second connecting member to move toward the ground along the second direction, the first connecting member is inserted into the avoidance groove on the second connecting member, so that an embedded connection relationship is formed between the first connecting member and the second connecting member. The second connecting member moves in the opposite direction along the second direction, and can be quickly separated from the first connecting member.

[0052] In this way, by setting an avoidance groove 301 in one of the first connecting member 30 or the second connecting member 40, and constructing the other of the first connecting member 30 and the second connecting member 40 as a protrusion, one of the first connecting member 30 and the second connecting member 40 can be moved along the second direction to form a plug-in embedded connection between the two to complete the connection between the first connecting member 30 and the second connecting member 40. The removal process is also fast and convenient. There is no need to remove fasteners such as screws during installation and removal, thereby realizing quick installation and quick removal of the cover assembly 1, thereby improving the installation and maintenance efficiency of the cover assembly 1.

[0053] In another embodiment, the avoidance groove 301 is formed on the first connecting member 30, and the notch of the avoidance groove 301 is connected to the surface of the first connecting member 30 facing away from the opening of the first accommodating groove 103; the second connecting member 40 is embedded in the avoidance groove 301 along the second direction, and the first connecting member 30 and the second connecting member 40 are limited to each other along the first direction; the second connecting member 40 can be moved out of the avoidance groove 301 along the second direction to separate the second cover body 20 from the first cover body 10.

[0054] See also Figure 3 The first connecting member 30 is provided with an escape groove 301, the notch of the escape groove 301 is connected to the upper surface of the first connecting member 30, that is, the surface of the first connecting member 30 away from the discharge pipe, and the escape groove 301 extends along the second direction. The escape groove 301 is provided on the portion of the first connecting member 30 located outside the first cover body 10, so that the escape groove 301 can be exposed to the first cover body 10 along the first direction.

[0055] See also Figure 4, the second connecting member 40 is constructed as a convex block, which is protruded from the second cover body 20. Before the second cover body 20 is buckled on the drain pipe, the second connecting member 40 can be aligned with the avoidance groove 301, and then the second cover body 20 can be moved downward, so that the two operations of buckling the second cover body 20 on the drain pipe and inserting the second connecting member 40 into the avoidance groove 301 can be completed at the same time. After the second connecting member 40 is inserted into the avoidance groove 301, the first connecting member 30 and the second connecting member 40 form a limit in the first direction with each other, so that the first cover body 10 and the second cover body 20 form a limit in the first direction, and there will be no movement between the first cover body 10 and the second cover body 20, thereby ensuring the walking safety of the staff stepping on the cover assembly 1.

[0056] When it is necessary to remove the second cover body 20 or the entire cover body assembly 1, the staff can lift the second cover body 20 upward along the second direction, so that the second connecting member 40 moves along the second direction with the second cover body 20 and disengages from the avoidance groove 301 and separates from the first connecting member 30, thereby separating the first cover body 10 and the second cover body 20.

[0057] Thus, by providing the avoidance groove 301 in the first connecting member 30 and configuring the second connecting member 40 as a convex block, the second connecting member 40 can be moved downward along the second direction so that the two can form a plug-in embedded connection, and the actions of installing the second cover 20 on the drain pipe and connecting the first cover 10 and the second cover 20 can be completed simultaneously. The removal process is also fast and convenient, and there is no need to remove fasteners such as screws during the installation and removal process, thereby realizing the quick installation and quick removal of the cover assembly 1, and improving the installation and maintenance efficiency of the cover assembly 1.

[0058] Optionally, the thickness of the second connecting member 40 is greater than or equal to the thickness of the first connecting member 30 .

[0059] It can be understood that when the thickness of the second connecting member 40 is greater than or equal to the thickness of the first connecting member 30 , the stability of the embedding relationship between the first connecting member 30 and the second connecting member 40 can be further ensured.

[0060] In this way, during the use of the cover body assembly 1, even if the friction force along the first direction is generated on the first cover body 10 and the second cover body 20 due to the staff's walking, since the thickness of the second connecting member 40 is greater than or equal to the thickness of the first connecting member 30, the second connecting member 40 will stably limit the avoidance groove 301 on the first connecting member 30, and the second connecting member 40 and the avoidance groove 301 will be avoided from moving along the first direction, so that the first cover body 10 and the second cover body 20 will not move along the first direction.

[0061] In another embodiment, the avoidance groove 301 includes an arcuate groove bottom 302, and the second connecting member 40 has an arcuate surface 401 that cooperates with the arcuate groove bottom 302. When the second connecting member 40 forms an embedded connection with the first connecting member 30, the arcuate surface 401 of the second connecting member 40 abuts against the arcuate groove bottom 302 of the avoidance groove 301.

[0062] In this example, see Figure 4 The groove bottom of the avoidance groove 301 is configured as an arc-shaped groove bottom 302 , and accordingly, the surface of the second connecting member 40 that matches the arc-shaped groove bottom 302 is configured as an arc-shaped surface 401 .

[0063] It can be understood that the arc surface 401 of the second connecting member 40 is formed at the insertion end of the second connecting member 40, so that when the second connecting member 40 is inserted into the avoidance groove 301, the jamming can be reduced, making the installation process smoother. On the other hand, since the groove bottom of the avoidance groove 301 is constructed as an arc groove bottom 302, and the insertion end of the second connecting member 40 is constructed as an arc surface 401, in the process of the two abutting, the cooperation between the two arc surfaces 401 can form a certain buffer protection for both the first connecting member 30 and the second connecting member 40, preventing the second connecting member 40 from being subjected to excessive force during the downward movement, thereby causing damage to its own corners or damaging the avoidance groove 301.

[0064] In another embodiment, the first cover body 10 includes: a first cover plate 101; two first side plates 102, respectively connected to the first cover plate 101, a first connecting member 30 is arranged on the first side plate 102, at least a portion of the first connecting member 30 protrudes from the first side plate 102 along the first direction, and an avoidance groove 301 is arranged on the portion of the first connecting member 30 protruding from the first side plate 102; the second cover body 20 includes: a second cover plate 201; two second side plates 202, respectively connected to the second cover plate 201, a second connecting member 40 is arranged on the second side plate 202, and is located at a position corresponding to the avoidance groove 301.

[0065] In this embodiment, the first cover body 10 includes a first cover plate 101 and two first side plates 102 connected to the sides of the first cover plate 101. The two first side plates 102 and the first cover plate 101 construct a first accommodating groove 103. The first cover plate 101 can be integrally formed with the two first side plates 102 to ensure the overall structural strength of the first cover body 10.

[0066] There can be two first connectors 30, which are respectively disposed on the two first side panels 102. Accordingly, there can also be two second connectors 40. In this way, it can be ensured that the first connector 30 and the second connector 40 can form a stable embedded connection on the two first side panels 102.

[0067] A portion of the first connecting member 30 is connected to the first side panel 102, and the other portion of the first side panel 102 can be exposed at the end of the first side panel 102 along the first direction. The avoidance groove 301 is arranged at the portion of the first connecting member 30 exposed at the first side panel 102, so that the second connecting member 40 can be smoothly inserted into the avoidance groove 301.

[0068] The first connecting member 30 is disposed on the first side plate 102 , so that the first connecting member 30 can be located on the side of the first cover body 10 , thereby not occupying the space on the first cover plate 101 , keeping the first cover plate 101 flat, and preventing the staff from tripping over the first connecting member 30 .

[0069] The second cover body 20 includes a second cover plate 201 and two second side plates 202 connected to the sides of the second cover plate 201. The two second side plates 202 and the second cover plate 201 construct a second accommodating groove 203. The second cover plate 201 can be integrally formed with the two second side plates 202 to ensure the overall structural strength of the second cover body 20.

[0070] The second connecting member 40 may be disposed on the second side plate 202 , and the second connecting member 40 is located at a corresponding position corresponding to the avoidance groove 301 of the first connecting member 30 to ensure that the second connecting member 40 can be smoothly inserted into the first connecting member 30 .

[0071] The second connecting member 40 is arranged on the second side plate 202 , so that the second connecting member 40 can be located on the side of the second cover body 20 , thereby not occupying the space on the second cover plate 201 , so that the second cover plate 201 remains flat, and the staff is prevented from being tripped by the second connecting member 40 .

[0072] Further, a first distance is formed between the second connecting member 40 and the end of the second side plate 202 along the first direction, and a first distance L is formed between the avoidance groove 301 and the end of the first side plate 102 .

[0073] Specifically, there is a first distance L between the surface of the second connecting member 40 close to the end of the second side plate 202 and the end of the second side plate 202, and the distance between the surface of the avoidance groove 301 close to the end of the first side plate 102 and the end of the first side plate 102 can be close to the first distance L.

[0074] In this way, it is not only possible to ensure that the second connecting member 40 can be smoothly inserted into the avoidance groove 301, but also possible to ensure that the first side plate 102 and the second side plate 202 are close to or form abutment when the second connecting member 40 is inserted into the avoidance groove 301 of the first connecting member 30, and the first cover plate 101 and the second cover plate 201 are close to or form abutment, so that a relatively close matching relationship can be ensured between the first cover body 10 and the second cover body 20. On the one hand, it is further ensured that the first cover body 10 and the second cover body 20 are mutually limited along the first direction, and on the other hand, it is also ensured that the connection gap between the first cover body 10 and the second cover body 20 is small, so as to be more conducive to the comprehensive protection of the drain pipe. In particular, in an environment where the cover assembly 1 is suitable for outdoor use, it is possible to prevent rainwater and pollutants from entering the first receiving groove 103 and the second receiving groove 203.

[0075] In another possible embodiment, the avoidance groove is formed on the second connecting member, and the notch of the avoidance groove is connected to the surface of the second connecting member facing the opening of the second accommodating groove; the second connecting member moves along the second direction to allow the first connecting member to be embedded in the avoidance groove, and the second connecting member and the first connecting member are mutually limited along the first direction; the second connecting member can move along the second direction, the first connecting member escapes from the avoidance groove and is separated from the first connecting member, and the second cover body is separated from the first cover body.

[0076] In this embodiment, the avoidance groove is provided on the second connecting member (not shown in the figure), the notch of the avoidance groove is connected to the lower surface of the second connecting member, that is, the surface of the second connecting member facing the drain pipe, and the avoidance groove extends along the second direction. The avoidance groove is provided on the portion of the second connecting member located outside the second cover body, so that the avoidance groove can be exposed to the second cover body.

[0077] The first connecting member is constructed as a convex block, which is protruding from the first cover body. Before the second cover body is buckled on the drain pipe, the avoidance groove of the second connecting member can be aligned with the first connecting member, and then the second cover body can be moved downward, so that the two operations of buckling the second cover body on the drain pipe and placing the first connecting member into the avoidance groove of the second connecting member can be completed at the same time. After the first connecting member is placed in the avoidance groove, the first connecting member and the second connecting member form a limit in the first direction with each other, so that a limit in the first direction is formed between the first cover body and the second cover body, and the first cover body and the second cover body are prevented from moving, thereby ensuring the walking safety of the staff stepping on the cover assembly.

[0078] When it is necessary to remove the second cover body or the entire cover body assembly, the staff can lift the second cover body upward along the second direction, so that the second connecting member moves along the second direction with the second cover body, and the first connecting member escapes from the avoidance groove and separates from the second connecting member, thereby separating the first cover body and the second cover body.

[0079] Thus, by providing an avoidance groove in the second connecting member, configuring the first connecting member as a convex block, and moving the second connecting member downward along the second direction, the two can form a plug-in embedded connection, and the actions of installing the second cover body on the drain pipe and connecting the first cover body and the second cover body can be completed simultaneously. The removal process is also fast and convenient, and there is no need to remove fasteners such as screws during the installation and removal process, thereby realizing quick installation and quick removal of the cover assembly, and improving the installation and maintenance efficiency of the cover assembly.

[0080] Optionally, when the thickness of the first connecting member is greater than or equal to the thickness of the second connecting member, the stability of the embedding relationship between the first connecting member and the second connecting member can be further ensured.

[0081] Optionally, the avoidance groove arranged on the second connecting member may also include an arcuate groove bottom, and the first connecting member has an arcuate surface matching the arcuate groove bottom. When the second connecting member forms an embedded connection with the first connecting member, the arcuate surface of the second connecting member abuts against the arcuate groove bottom of the avoidance groove.

[0082] In another possible embodiment, the first connecting member 30 and the first cover body 10 are an integrally formed structure or a detachably connected structure; and / or the second connecting member 40 and the second cover body 20 are an integrally formed structure or a detachably connected structure.

[0083] In this embodiment, the first connecting member 30 can be integrally formed with the first cover body 10 by welding or fusing, so as to ensure the reliability of the connection between the first connecting member 30 and the first cover body 10 .

[0084] Optionally, the second connecting member 40 may be integrally formed with the second cover body 20 by welding or fusing, so as to ensure the reliability of the connection between the second connecting member 40 and the second cover body 20 .

[0085] Optionally, considering the possibility that the first connecting member 30 may crack, deform or be completely damaged during long-term use, the first connecting member 30 and the first cover body 10 can be detachably connected by fasteners. When the first connecting member 30 needs to be replaced, the first connecting member 30 can be removed from the first cover body 10 and replaced with a new one.

[0086] Optionally, the second connecting member 40 can also be detachably mounted to the second cover body 20 . When the second connecting member 40 needs to be replaced, the second connecting member 40 can be removed from the second cover body 20 and replaced with a new second connecting member 40 .

[0087] In another possible embodiment, along the second direction, the first connecting member 30 does not protrude from the surface of the first cover body 10 ; along the second direction, the second connecting member 40 does not protrude from the surface of the second cover body 20 .

[0088] In this embodiment, along the second aspect, the first connecting member 30 does not protrude from the surface of the first cover body 10. Specifically, the first connecting member 30 does not protrude from the surface of the first cover plate 101, thereby ensuring the flatness of the surface of the first cover plate 101, thereby ensuring that the staff will not be tripped by the first connecting member 30 while walking.

[0089] Similarly, along the second aspect, the second connecting member 40 does not protrude from the surface of the second cover body 20. Specifically, the second connecting member 40 does not protrude from the surface of the second cover plate 201, thereby ensuring the flatness of the surface of the second cover plate 201, thereby ensuring that the staff will not be tripped by the second connecting member 40 while walking.

[0090] The second aspect of the embodiment of the present application provides a cleaning device, which includes the cover assembly 1, a cleaning tank and a drain pipe provided in the embodiment of the first aspect of the present application. The cleaning tank is used to contain cleaning liquid, and a drain port is provided on the cleaning tank; the drain pipe is connected to the drain port and is used to discharge the cleaning liquid in the cleaning tank, the first cover body 10 and the second cover body 20 are covered on the drain pipe, and the drain pipe is located in the first receiving tank 103 and the second receiving tank 203.

[0091] Since the cleaning device includes the cover assembly 1 provided by any of the above embodiments of the present application, the cleaning device includes all the beneficial technical effects of the cover assembly 1, which will not be repeated here.

[0092] The cleaning tank can be used to clean silicon wafers or battery cells involved in the battery production process. The cleaning liquid contained in the cleaning tank is used to clean the silicon wafers or battery cells. During the cleaning process, the used cleaning liquid needs to be discharged from the cleaning tank, and the cleaning liquid is injected into the drain pipe through the drain port.

[0093] The drain pipe is accommodated in the first accommodating groove 103 and the second accommodating groove 203 of the cover body assembly 1, that is, the first cover body 10 and the second cover body 20 form a comprehensive covering for the drain pipe, thereby preventing the staff from stepping on the drain pipe when entering the working area, and preventing the drain pipe from being deformed due to stepping on, causing the cleaning liquid to flow out of the drain pipe.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
