[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] Since the long side and short side of the photovoltaic module are not proportional, it is easy to have arrangement gaps when the photovoltaic modules are arranged horizontally and vertically on the photovoltaic bracket, which affects the waterproof performance and overall aesthetics of the photovoltaic power station. Most existing photovoltaic power stations use color steel tiles to fill the gaps formed by the arrangement of photovoltaic modules. However, the size difference between the color steel tiles and the photovoltaic modules is large, resulting in the inability of the color steel tiles to fit well to fill the gaps formed after the photovoltaic modules of various sizes are arranged. The adaptability is poor and the problem of water leakage and aesthetics cannot be completely changed. In view of the above problems, the utility model proposes a cover assembly 100.

[0035] Reference Figures 1 to 7 In an embodiment of the utility model, the cover assembly 100 includes a mounting frame, a fixed cover 30 and an adjustable cover 50. A guide groove 11 is formed in the mounting frame. The fixed cover 30 is movably clamped in the guide groove 11. A fixed socket 31 is formed in the fixed cover 30. The fixed cover 30 is provided with a sealing fold 33. The sealing fold 33 can be bent and arranged in the fixed socket 31; the adjustable cover 50 is movably clamped in the guide groove 11, and part of the structure of the adjustable cover 50 is inserted in the fixed socket 31 and abuts against the sealing fold 33.

[0036] It is understandable that the photovoltaic power station can be erected on the roof of a building or on an open ground plane using a photovoltaic bracket, and then the photovoltaic module 300 can be laid and fixed on the support frame 200 of the photovoltaic bracket, so that the photovoltaic module 300 can stably absorb and convert light energy on the photovoltaic bracket, thereby ensuring the stable and reliable operation of the photovoltaic power station. Among them, since the shape of the photovoltaic module 300 is mostly a rectangular parallelepiped, when laying the photovoltaic module 300 on the support frame 200, some of the photovoltaic modules 300 can be arranged on the support frame 200 in multiple vertical rows with the short sides connected, and some of the photovoltaic modules 300 can be arranged on the support frame 200 in a horizontal direction with the short sides connected, so that the support frame 200 can be compatible with the photovoltaic modules 300 of various arrangements and then lay as many photovoltaic modules 300 as possible, making full use of the limited occupied space of the photovoltaic power station on the installation platform, and better improving the light energy utilization rate of the photovoltaic power station.

[0037] However, the long side and the short side of the photovoltaic module 300 are usually arranged in a disproportionate relationship, which causes a photovoltaic power station that is compatible with both horizontal and vertical arrangements of the photovoltaic modules 300 to easily form a gap on one side of the horizontally arranged photovoltaic module 300. The existence of the gap causes rainwater falling on the photovoltaic module 300 to easily drip from the gap onto the installation platform of the photovoltaic power station, causing water to easily accumulate under the photovoltaic bracket, affecting the waterproof performance of the photovoltaic power station; and the gap destroys the overall structural integrity of the photovoltaic power station, affecting the overall aesthetics of the photovoltaic power station.

[0038] In the present application, after the photovoltaic power station has arranged the photovoltaic module 300 on the photovoltaic support, the cover assembly 100 can be installed at the gap formed after the photovoltaic module 300 is arranged. The cover assembly 100 can be composed of a mounting frame, a fixed cover 30 and an adjustable cover 50. The mounting frame can be a frame structure with a retractable and adjustable size, or a frame structure made according to the size of the gap on the construction site, and the thickness of the mounting frame can match the thickness of the photovoltaic module 300, so that the cover assembly 100 can be set flush with the photovoltaic module 300 when filling the gap, thereby ensuring the overall aesthetics of the photovoltaic power station. By utilizing the guide groove 11 structure formed in the mounting frame, the fixed cover 30 and the adjustable cover 50 can be moved and clamped in the guide groove 11 structure, so that the fixed cover 30 and the adjustable cover 50 can be moved in the mounting frame to adjust the covering area of ​​the cover assembly 100. It should be noted that during the assembly process of the photovoltaic power station, installation components such as pressure blocks and clamps can be set on the support frame 200 of the photovoltaic bracket to connect and fix the installation frame of the cover assembly 100, or bolts or self-tapping screws can be used to penetrate and connect the support frame 200 and the installation frame, so that the cover assembly 100 can be stably assembled on the photovoltaic bracket to fill the gap formed after the photovoltaic assembly 300 is laid out, thereby better improving the practicality and reliability of the cover assembly 100.

[0039] At this time, the fixed cover 30 can be moved to one side of the mounting frame along the extension direction of the guide groove 11, and then the adjustable cover 50 is inserted into the fixed socket 31 of the fixed cover 30 toward one side of the fixed cover 30 as the adjustable cover 50 slides in the guide groove 11. By providing a bendable sealing fold 33 in the fixed socket 31, the sealing fold 33 can be a flange formed by folding the fixed cover 30 toward the side of the adjustable cover 50, and the elasticity of the sealing fold 33 in the fixed socket 31 can be achieved by utilizing the steel toughness of the fixed cover 30. Bending; or the sealing folded edge 33 can be made into an elastic baffle welded or adhesively fixed on the inner wall of the fixed socket 31, so that part of the structure of the adjustable cover 50 can abut against the sealing folded edge 33 when it is inserted into the fixed socket 31, and the abutting effect of the sealing folded edge 33 and the adjusting cover 50 can be used to effectively reduce the gap between the fixed cover 30 and the adjusting cover 50, and reduce rainwater, snow water, etc. from flowing through the gap between the fixed cover 30 and the adjusting cover 50 to the bottom of the cover assembly 100, thereby effectively ensuring the waterproof effect of the cover assembly 100. At the same time, when the adjustable cover 50 moves relative to the fixed cover 30, the elastic bending effect of the sealing fold 33 in the fixed socket 31 can be utilized to allow the sealing fold 33 to maintain contact with the portion of the adjustable cover 50 inserted in the fixed socket 31 during the movement of the adjustable cover 50. Therefore, in the process of adjusting the overall covering size of the cover assembly 100 by relative movement of the adjustable cover 50 and the fixed cover 30, a small gap between the adjustable cover 50 and the fixed cover 30 can be stably maintained, thereby improving the structural stability and waterproof performance of the cover assembly 100.

[0040] Therefore, during the construction of the photovoltaic assembly 300, the adjustable cover plate 50 and the fixed cover plate 30 can be moved in the mounting frame according to the size of the gap formed after the photovoltaic assembly 300 is arranged on the photovoltaic bracket, and the overall shielding area of ​​the cover plate assembly 100 can be adjusted by increasing or reducing the part of the adjustable cover plate 50 inserted in the fixed cover plate 30, so that the cover plate assembly 100 can better adapt to the gaps formed after the photovoltaic assembly 300 of various sizes is arranged, and the practicality of the cover plate assembly 100 is guaranteed. The cover plate assembly 100 uses the fixed cover plate 30 and the adjustable cover plate 50 that are spliced ​​with each other, so that the cover plate assembly 100 can better correspond to the thickness size and shape structure setting of the photovoltaic assembly 300, and the cover plate assembly 100 can be kept flush with the photovoltaic assembly 300, so as to ensure the integrity of the cover plate assembly 100 and the photovoltaic assembly 300, which is conducive to better improving the overall aesthetics of the photovoltaic power station. By providing a sealing folded edge 33 with a certain elasticity and bendable arrangement in the fixed socket 31 of the fixed cover plate 30, the sealing folded edge 33 can be used to abut the adjustable cover plate 50 to reduce the gap between the fixed cover plate 30 and the adjustable cover plate 50, thereby achieving a higher waterproof performance, thereby enabling the cover plate assembly 100 to better fill the gap formed after the photovoltaic assembly 300 is arranged on the photovoltaic bracket, thereby improving the practicality and reliability of the cover plate assembly 100.

[0041] Among them, the cover assembly 100 can be assembled into a whole during the production process. During the construction process, the cover assembly 100 is directly installed corresponding to the gap formed after the photovoltaic assembly 300 is laid out, and then the adjustable cover 50 and the fixed cover 30 are moved to adjust the overall size of the cover assembly 100. Alternatively, the size of the mounting frame can be adjusted according to the gap formed after the photovoltaic assembly 300 is laid out at the construction site, so that the mounting frame can better cover the surrounding areas of the gap, and then the fixed cover 30 and the adjustable cover 50 are successively installed from one side of the mounting frame, and the fixed cover 30 and the adjustable cover 50 are moved to adjust the overall covering area of ​​the cover assembly 100, so as to ensure that the cover assembly 100 fully fills the gap formed after the photovoltaic assembly 300 is laid out, thereby further improving the practicality and reliability of the cover assembly 100. After the fixed cover plate 30 and the adjustable cover plate 50 are adjusted, the sealing fold 33 can be used to abut the adjustable cover plate 50 to limit the fixed cover plate 30 and the adjustable cover plate 50. The photovoltaic assembly 300 and the support frame 200 of the photovoltaic bracket can be used to abut the opposite sides of the fixed cover plate 30 and the adjustable cover plate 50 respectively to achieve the fixed assembly of the cover plate assembly 100 on the support frame 200 of the photovoltaic bracket; or the mounting components on the support frame 200 of the photovoltaic bracket can be used to fix the fixed cover plate 30 and the adjustable cover plate 50; or the corresponding clamping structure or connecting structure can be set inside the cover plate assembly 100 to fix the position of the fixed cover plate 30 and the adjustable cover plate 50 on the mounting frame. In addition, the relative displacement of the fixed cover plate 30 and the adjustable cover plate 50 after the cover plate assembly 100 is assembled can be prevented, so that the cover plate assembly 100 can stably fill the gap formed after the photovoltaic assembly 300 is arranged, and the practicality and reliability of the cover plate assembly 100 are further improved.

[0042] Reference Figure 4 , Figure 5 and Figure 7 In one embodiment of the utility model, the adjustment cover 50 includes a main board section 51 and a plug-in section 53. The main board section 51 is clamped in the guide groove 11; the plug-in section 53 is connected to one side of the main board section 51, and the plug-in section 53 is inserted into the fixed socket 31 and abuts against the sealing folded edge 33.

[0043] In this embodiment, the adjustable cover plate 50 can be provided with a sliding structure on the main board section 51 that matches the guide groove 11 of the mounting frame, which can be a slider or a pulley that slides and snaps into the guide groove 11 on the side of the main board section 51 facing the guide groove 11; or the thickness of the main board section 51 can be set to correspond to the size of the guide groove 11, so that the mounting frame can use the guide groove 11 to clamp the main board section 51 to achieve the movement of the adjustable cover plate 50 in the mounting frame. By providing a plug-in section 53 on one side of the main board section 51, the plug-in section 53, which is slightly smaller than the main board section 51, can be plugged into the fixed socket 31 to achieve a stable connection between the fixed cover plate 30 and the adjustable cover plate 50, and the plug-in section 53 with a smaller size can be more conveniently plugged into the fixed socket 31, thereby improving the convenience of operation of the cover plate assembly 100. In addition, by plugging the plug-in section 53, which is smaller than the main board section 51, into the fixed cover plate 30, the adjustable cover plate 50 and the fixed cover plate 30 can be better prevented from being stuck to each other, thereby ensuring the stability and reliability of the relative movement of the adjustable cover plate 50 and the fixed cover plate 30, and further improving the practicality and reliability of the cover plate assembly 100.

[0044] Reference Figure 4 and Figure 7 In one embodiment of the present utility model, the main board segment 51 is defined to have a shielding plane, and the plug-in segment 53 is arranged to be inclined to the shielding plane of the main board segment 51 .

[0045] In this embodiment, the top surface of the main board segment 51 can be a plane parallel to or flush with the surface of the photovoltaic module 300, so that the main board segment 51 can block the plane relatively flatly, so that the cover assembly 100 can better ensure the overall aesthetics of the photovoltaic power station. By making the top surface of the plug-in segment 53 inclined to the blocking plane, the plug-in segment 53 can be arranged in a shuttle-shaped structure, so that the adjustable cover 50 can insert the plug-in segment 53 into the fixed plug hole 31 at a lower insertion angle, and under the action of the inclined plug-in segment 53, it can more smoothly abut the sealing fold 33 to push the sealing fold 33 to bend, which is conducive to better reducing the reaction force received by the adjustable cover 50 when it is moved and inserted into the fixed cover 30, and further improving the convenience of operation of the cover assembly 100.

[0046] Reference Figure 5 and Figure 7 In one embodiment of the present invention, a water collecting edge 531 is provided on a side of the plug-in section 53 facing away from the main board section 51 , and a water collecting groove 533 is formed on the water collecting edge 531 .

[0047] In this embodiment, a water collecting edge 531 is provided on the side of the plug-in section 53 facing away from the main board section 51. The water collecting edge 531 can be a flange structure formed by bending one side of the plug-in section 53, or an arc-shaped baffle can be welded or bonded on one side of the plug-in section 53 to form the water collecting edge 531. A water collecting trough 533 can be formed at the connection between the water collecting edge 531 and the plug-in section 53. When rainwater or snow water falls on the cover assembly 100 and flows on the plug-in section 53, the water collecting trough 533 can be used to collect the water falling on the plug-in section 53, which is beneficial to better prevent the water flowing through the gap between the plug-in section 53 and the sealing folded edge 33 from falling under the cover assembly 100, thereby achieving better waterproof performance of the cover assembly 100 and further improving the practicality and reliability of the cover assembly 100. The water collected in the water collecting tank 533 can flow to the mounting frame through both sides of the water collecting tank 533, and flow into the drainage tank on the supporting frame 200 through the opening on the mounting frame for centralized discharge, thereby ensuring the overall waterproof performance of the photovoltaic bracket.

[0048] In addition, when the plug-in section 53 is connected to the main board section 51 at an angle, the inclined setting of the plug-in section 53 can better enable part of the rainwater or snow water falling on the adjusting cover plate 50 to flow into the water collecting trough 533 for discharge, thereby ensuring the stable operation of the photovoltaic power station and further improving the structural stability and reliability of the cover plate assembly 100. Secondly, the water collecting edge 531 can also form a limiting structure for the movement of the adjusting cover plate 50 in the mounting frame after the adjusting cover plate 50 is inserted into the fixed plug hole 31 of the fixed cover plate 30. When the adjusting cover plate 50 moves in a direction away from the fixed cover plate 30, the water collecting edge 531 can be engaged with the sealing folding edge 33 when the adjusting cover plate 50 moves to a certain position, thereby limiting the further movement of the adjusting cover plate 50, which is conducive to preventing the adjusting cover plate 50 from being over-adjusted and separated from the fixed cover plate 30, and ensuring the connection stability and reliability between the adjusting cover plate 50 and the fixed cover plate 30.

[0049] Reference Figure 3 , Figure 5 and Figure 7 In one embodiment of the utility model, an extension socket 511 is provided in the main board segment 51, and the cover assembly 100 includes at least two adjustment covers 50. The plug-in segment 53 of one adjustment cover 50 is inserted into the extension socket 511 of another adjacent adjustment cover 50 and abuts against the main board segment 51 of the adjustment cover 50. At least two adjustment covers 50 are plugged and arranged in sequence.

[0050] In this embodiment, the adjustment cover 50 can also form an extension socket 511 in the main board section 51. The size of the extension socket 511 can be set corresponding to the size of the fixed socket 31, so that multiple adjustment covers 50 can be plugged in with each other to achieve extended assembly of the adjustment cover 50. Furthermore, when a larger gap needs to be filled, the cover assembly 100 can be configured with multiple adjustable cover plates 50. The plug-in section 53 of an adjustable cover plate 50 can be inserted into the fixed socket 31 of the fixed cover plate 30, and then the plug-in sections 53 of the remaining adjustable cover plates 50 are inserted into the extended socket 511 of the previous adjustable cover plate 50 in sequence. The multiple adjustable cover plates 50 can be arranged in sequence in the mounting frame, and the coordinated connection of the multiple adjustable cover plates 50 and the fixed cover plate 30 can be effectively utilized to increase the overall shielding area of ​​the cover assembly 100, thereby ensuring the effect of the cover assembly 100 in filling the gap after the photovoltaic components 300 are arranged, so that the cover assembly 100 can be better adapted to the gaps formed after the various photovoltaic components 300 are arranged, thereby further improving the practicality and reliability of the cover assembly 100.

[0051] Reference Figure 7 In one embodiment of the utility model, the main board section 51 is provided with a flow-blocking fold 513, and the flow-blocking fold 513 is bent in the extension socket 511, and the flow-blocking fold 513 of an adjustment cover 50 is used to abut against the plug-in section 53 of another adjacent adjustment cover 50.

[0052] In this embodiment, a bendable flow-blocking folded edge 513 can be provided in the extension socket 511 of the adjusting cover plate 50. The flow-blocking folded edge 513 can be a flange formed by folding inward on the side of the main board section 51 facing away from the plug-in section 53. The toughness of the steel material of the adjusting cover plate 50 can be utilized to realize the elastic bending of the flow-blocking folded edge 513 in the extension socket 511; or the flow-blocking folded edge 513 can be an elastic baffle welded or adhesively fixed on the inner wall of the extension socket 511, so that when the plug-in section 53 of another adjusting cover plate 50 is inserted into the extension socket 511, it can abut against the flow-blocking folded edge 513, and the abutting effect of the flow-blocking folded edge 513 and the plug-in section 53 of another adjusting cover plate 50 can be utilized to effectively reduce the gap at the plug-in point of two adjacent adjusting cover plates 50, thereby reducing rainwater, snow water, etc. from flowing through the connection gap between the two adjacent adjusting cover plates 50 to the bottom of the cover plate assembly 100, thereby effectively ensuring the waterproof effect of the cover plate assembly 100. At the same time, when two adjacent adjustable cover plates 50 move relative to each other, the elastic bending effect of the flow-blocking fold 513 in the extension socket 511 can be utilized to ensure that the flow-blocking fold 513 can maintain the abutment between the flow-blocking fold 513 and the plug-in section 53 of the other adjustable cover plate 50 during the relative movement of the adjustable cover plate 50. Therefore, in the process of adjusting the overall covering size of the cover plate assembly 100 by moving the adjustable cover plate 50, the smaller gap between adjacent adjustable cover plates 50 can be stably maintained, thereby improving the structural stability and waterproof performance of the cover plate assembly 100, and further improving the practicality and reliability of the cover plate assembly 100.

[0053] In one embodiment of the present invention, the cover plate assembly 100 further includes a connecting member, which connects the fixed mounting frame and the fixed cover plate 30 , and / or the connecting member connects the fixed mounting frame and the adjustable cover plate 50 .

[0054] In this embodiment, the cover assembly 100 can use connecting parts to connect the fixed mounting frame with the fixed cover 30 and the adjustable cover 50, so as to avoid the relative offset between the fixed cover 30 and the adjustable cover 50 after the cover assembly 100 is installed, thereby affecting the covering of the gap formed by the layout of the photovoltaic component 300 by the cover assembly 100, thereby further improving the structural stability and reliability of the cover assembly 100.

[0055] The connecting member may be a screw or a self-tapping screw, etc., and the connecting member may be inserted through the side wall of the mounting frame and the side wall of the fixed cover plate 30 to achieve the connection and fixation of the mounting frame and the fixed cover plate 30. Similarly, the connecting member in the form of a screw or a self-tapping screw may be inserted through the side wall of the mounting frame and the side wall of the adjustable cover plate 50 to achieve the connection and fixation of the mounting frame and the adjustable cover plate 50.

[0056] Alternatively, the connector can be made of materials such as glue, and the connector can be poured between the inner wall of the guide groove 11 and the surface of the fixed cover plate 30, so that the connector adheres to the mounting frame and the fixed cover plate 30 to achieve a stable connection and fixation between the two. Similarly, the connector made of materials such as glue can be poured between the inner wall of the guide groove 11 and the surface of the adjustable cover plate 50, so that the connector adheres to the mounting frame and the adjustable cover plate 50 to achieve a stable connection and fixation between the two.

[0057] Furthermore, under the action of the connecting piece, the overall size of the cover assembly 100 after adjustment can be firmly maintained, so that the cover assembly 100 can more stably fill the gap formed after the photovoltaic assembly 300 is arranged, further improving the practicality and reliability of the cover assembly 100.

[0058] Reference Figure 5 and Figure 6 In one embodiment of the utility model, the mounting frame is provided with two oppositely arranged connecting rods 10, and the connecting rods 10 are provided with guide grooves 11. The opposite sides of the fixed cover plate 30 are respectively clamped in the guide grooves 11 of the two connecting rods 10, and the opposite sides of the adjustable cover plate 50 are respectively clamped in the guide grooves 11 of the two connecting rods 10.

[0059] In this embodiment, the mounting frame may include two connecting rods 10 arranged opposite to each other, and guide grooves 11 may be recessed on the side surfaces of the two connecting rods 10 facing each other, so that the fixed cover plate 30 and the adjustable cover plate 50 can be clamped in the guide grooves 11 of the two connecting rods 10. A slider or pulley corresponding to the guide groove 11 may be provided on the side of the fixed cover plate 30 or the adjustable cover plate 50 facing the connecting rod 10, and the slider or pulley is used to slide in the guide groove 11 to realize the movement of the fixed cover plate 30 and the adjustable cover plate 50 in the mounting frame; or the opening size of the guide groove 11 can be set to correspond to the side thickness of the fixed cover plate 30 or the side thickness of the adjustable cover plate 50, so that the guide groove 11 can clamp the side of the fixed cover plate 30 or the side of the adjustable cover plate 50 to realize the movement of the fixed cover plate 30 and the adjustable cover plate 50 in the mounting frame, thereby better ensuring the stability and reliability of the movement of the fixed cover plate 30 and the adjustable cover plate 50 in the mounting frame. By using two connecting rods 10 to respectively clamp the opposite sides of the adjustable cover plate 50 and the opposite sides of the fixed cover plate 30, the connection stability and reliability of the fixed cover plate 30 and the adjustable cover plate 50 and the mounting frame can be better improved, which is conducive to better preventing the fixed cover plate 30 or the adjustable cover plate 50 from slipping and derailing in the mounting frame, and further improving the overall structural stability and reliability of the cover plate assembly 100.

[0060] Reference Figure 5 and Figure 6In one embodiment of the utility model, the connecting rod 10 includes a top plate 13, a bottom plate 15 and a side plate 17, the top plate 13 is provided with a drain port 131; the bottom plate 15 is arranged opposite to the top plate 13, and is used to be installed on the support frame 200 of the photovoltaic bracket; the side plate 17 connects the top plate 13 and the bottom plate 15, and is enclosed with the top plate 13 and the bottom plate 15 to form a guide groove 11.

[0061] In this embodiment, the connecting rod 10 can be a structure similar to a "C" shape formed by connecting a top plate 13, a bottom plate 15 and a side plate 17, which is conducive to better simplifying the overall structure of the connecting rod 10. At this time, the cover assembly 100 can use the bottom plate 15 of the connecting rod 10 to be connected to the support frame 200 of the photovoltaic bracket, and correspondingly arranged on the gutter structure exposed at the notch of the support frame 200, so that rainwater or snow water falling on the cover assembly 100 can flow to the bottom plates 15 of the two connecting rods 10 through the two sides of the adjustable cover plate 50 and the fixed cover plate 30, and then fall into the gutter structure for centralized discharge, preventing water falling on the cover assembly 100 from flowing to the bottom of the cover assembly 100 and causing water accumulation under the photovoltaic bracket with a certain probability, further improving the practicality and structural reliability of the mounting frame.

[0062] Since the fixed cover plate 30 and the adjustable cover plate 50 are moved and adjusted by being clamped in the guide groove 11 of the connecting rod 10, the surface of the top plate 13 can be slightly higher than the surface of the fixed cover plate 30 and the surface of the adjustable cover plate 50. At this time, rainwater, snow water, etc. falling on the cover plate assembly 100 are likely to accumulate on the surfaces of the fixed cover plate 30 and the adjustable cover plate 50 due to the height difference between the top plate 13 and the fixed cover plate 30 and the adjustable cover plate 50 to form water accumulation, thereby increasing the load of the cover plate assembly 100. At this time, by setting a drain port 131 on the top plate 13, the drain port 131 can penetrate the side wall of the top plate 13 facing away from the side plate 17, so that rainwater or snow water falling on the plate surface of the adjusting cover plate 50 and the fixed cover plate 30 can flow into the guide groove 11 through the drain port 131 and flow into the water tank under the connecting rod 10 through the bottom plate 15 for centralized discharge, which is beneficial to better reduce the load on the cover plate assembly 100, ensure the stable drainage of the cover plate assembly 100, and further improve the structural stability and practicality of the cover plate assembly 100.

[0063] Reference Figure 6 In one embodiment of the present utility model, the bottom plate 15 is provided with a water outlet 151 .

[0064] In this embodiment, the connecting rod 10 can also be provided with a drain port 151 on the bottom plate 15, and the position of the drain port 151 is set to correspond to the slot position of the water tank structure of the support frame 200. Then, under the action of the drain port 151, the water falling on the surface of the cover assembly 100 can be more stably made to flow into the guide groove 11 through the edges of the adjusting cover plate 50 and the fixed cover plate 30. Then, under the action of gravity, the water flow can be gathered on the bottom plate 15 and flow into the water tank structure through the drain port 151, which is beneficial to better ensure the stable discharge of water on the cover assembly 100 and improve the drainage efficiency of the cover assembly 100. At the same time, it is also beneficial to reduce the overflow of water on the bottom plate 15 and reduce the splashing of water when the cover assembly 100 is drained, so as to better improve the waterproof performance of the cover assembly 100 and further improve the overall structural stability and reliability of the cover assembly 100.
