Description

Technical Field

[0001] The present invention relates to the technical field of brackets, and in particular to an external wall bracket which is convenient for cleaning photovoltaic panels. Background Art

[0002] Photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They are composed of thin-film solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Installing photovoltaic panels on the exterior walls of buildings not only further utilizes the exterior wall space of the building, but also converts light energy into electrical energy.

[0003] Factors that affect the power generation of photovoltaic panels include: the angle between the photovoltaic panel and the sun's rays, dust covering the surface of the photovoltaic panel, the temperature of the photovoltaic panel, etc. In the existing photovoltaic brackets, there is a mechanism that can follow the light. First of all, adding this structure will undoubtedly increase the cost. Secondly, for brackets installed on the exterior wall of a building, if there are movable parts, under the influence of wind and other factors, the risk of damage to the movable structure is high, and the safety hazard is relatively large. Therefore, most of the existing photovoltaic panel exterior wall brackets adopt a fixed structure, but they are only used to fix the photovoltaic panel, and the convenience of maintenance and repair is not considered. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses an external wall bracket for convenient cleaning of photovoltaic panels, including a fixed frame and a supporting frame, the supporting frame including a second channel steel frame, the fixed frame including a first channel steel frame, and the first channel steel frame and the second channel steel frame have the same appearance, with a side opening, and the side wall of the first channel steel frame is fixedly connected with a square steel, and the square steel is matched with the inner side of the second channel steel frame. The bracket used by the existing photovoltaic panels is basically directly fixed, and the fixed parts need to be unscrewed to remove the photovoltaic panels. In this solution, a fixed frame and a supporting frame are provided, the fixed frame is used to fix the photovoltaic panels, and the supporting frame is fixedly connected to the external wall of the building, and the fixed frame can be pulled out from the supporting frame, which is convenient for the inspection, maintenance, replacement and other operations of the photovoltaic panels. It should be noted that in order to facilitate the operation of the photovoltaic panels, the supporting frame is fixedly connected to the wall at the balcony, so that personnel can directly operate the photovoltaic panels and operate in reverse.

[0005] A water trough is provided at the lower part of the first channel steel frame, and the length of the water trough is consistent with the width of the second channel steel frame, and the water trough is provided close to the first channel steel frame. One of the factors affecting the power generation of photovoltaic panels is the thickness of the dust covering the surface of the photovoltaic panels. The thicker the dust is, the greater the light is blocked, which is not conducive to the power generation of the photovoltaic panels. Therefore, the surface of the photovoltaic panels needs to be cleaned regularly. However, in this scheme, the photovoltaic panels are fixedly connected to the outer wall. If they are cleaned directly, the water stains dripping from the photovoltaic panels during the cleaning process will affect the pedestrians or green plants downstairs. In this scheme, a water trough is provided. During the cleaning process, water will flow into the water trough to reduce water dripping. At the same time, the relevant cleaning tools can be directly dipped in water in the water trough, which is conducive to the cleaning of the photovoltaic panels. The water in the water trough is evaporated in the daily process, and there is no need to worry about the problem of water post-treatment. You only need to remove the water trough regularly to clean the inside.

[0006] Furthermore, the space of the water tank is divided into two areas, the side close to the photovoltaic panel collects cleaning water, and the side outside is used to plant flowers and green plants, etc., which can not only improve the aesthetics of the outer circle, but also the water generated by cleaning the photovoltaic panel can be used for watering flowers and green plants, and the dust on the surface of the photovoltaic panel can also provide inorganic salt nutrition for flowers and green plants, which can achieve multiple effects at one stroke. A baffle is arranged on one side of the opening of the first channel steel frame, and second bolts are inserted at both ends of the baffle, and the second bolts are threadedly connected with the square steel. The baffle is arranged and combined with the first channel steel frame to form a closed frame.

[0007] The second channel steel frame is tilted, and a plurality of support rods are fixedly connected to the back of the second channel steel frame. The support rods are horizontally arranged, and the other ends of the support rods are fixedly connected to a mounting plate, and the mounting plate is provided with through holes. The second channel steel frame is tilted, and the tilt angle can refer to the local latitude. At this time, the lengths of the support rods connected to the upper and lower parts of the second channel steel frame are different. If it is to improve the aesthetics of the building's exterior wall, the second channel steel frame can also be set vertically. At this time, the lengths of the support rods connected to the upper and lower parts are the same. Further, expansion bolts are used to pass through the through holes to fix the support frame to the exterior wall. If a connection structure is reserved during the exterior wall construction, such as a threaded hole on an embedded part, bolts can be used to pass through the through holes and threadedly fit on the embedded part.

[0008] Preferably, the upper side wall of the second channel steel frame is provided with a side plate, the lower part of the side plate is fixed, and the upper part is bent, that is, the side plate can be bent by pulling from the upper bending part of the side plate, and after releasing, the side plate can automatically restore to its original state.

[0009] Preferably, a snap-fit ​​block is fixedly connected to the upper part of the side plate, and one side of the upper part of the snap-fit ​​block is provided with an inclined surface, and a snap-fit ​​hole is provided on the upper side wall of the square steel, and one side of the snap-fit ​​block fits in the snap-fit ​​hole. When the first channel steel frame slides and fits into the interior of the second channel steel frame, the snap-fit ​​block fits in the snap-fit ​​hole to limit the first channel steel frame and prevent the first channel steel frame from being pushed out. If the first channel steel frame is to be taken out, the side plate needs to be pulled, and the side plate bends and the snap-fit ​​block is disengaged from the snap-fit ​​hole, and the first channel steel frame can be pulled out at this time. It should be noted that the snap-fit ​​holes are provided on both sides of the first channel steel frame, so when disassembling the first channel steel frame, two people are required to pull the side plates on both sides at the same time to improve the safety of the operation.

[0010] Preferably, reinforcing rods are arranged between the support rods, and the reinforcing rods include vertically arranged rods and obliquely arranged rods. There are two obliquely arranged rods, which are arranged in an "X" shape, and the ends are connected to the end side walls of the vertically arranged rods, while the vertically arranged rods are used to connect the support rods at adjacent upper and lower positions. The purpose of setting the reinforcing rods is to improve the structural strength of the device.

[0011] Preferably, a plurality of screws are fixedly connected to the lower front part of the first channel steel frame, and the screws penetrate the upper part of the water tank, and nuts are provided on the screws to cooperate with the threads. The water tank is fixedly connected to the first channel steel frame through the structure of the screws and nuts, and the water tank can be disassembled according to the installation needs.

[0012] Preferably, the back of the first channel steel frame is threadedly matched and penetrated with a first bolt. When the photovoltaic is fixed, it is installed inside the first channel steel frame, and the end of the first bolt abuts against the frame of the photovoltaic panel to achieve its fixing operation, and a plurality of first bolts are provided to ensure reliable fixing.

[0013] Preferably, a handle is fixedly connected to the middle of the upper end of the baffle, that is, the photovoltaic panel can be pulled out of the first channel steel frame by holding the handle and lifting it up.

[0014] The beneficial effects of the present invention are as follows: 1. Split the bracket into a supporting frame and a fixed frame. The supporting frame is fixedly connected to the exterior wall of the building, while the fixed frame is used to install the photovoltaic panels. The two are connected by sliding grooves. In addition, the bracket is in a completely fixed state to meet the application scenarios of the exterior wall. It can be split if needed to facilitate the maintenance and repair of the photovoltaic panels.

[0015] 2. A water tank is provided, and the lower part of the first channel steel frame of the water tank can receive the water generated during the cleaning process of the photovoltaic panels to reduce the impact on the bottom of the building. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Combination Figures 1 to 7As shown, an external wall bracket for convenient cleaning of photovoltaic panels includes a fixed frame 2 and a supporting frame 3, that is, the bracket is provided with two parts and is designed to be split, the supporting frame 3 includes a second channel steel frame 31, the fixed frame 2 includes a first channel steel frame 21, and the first channel steel frame 21 and the second channel steel frame 31 have the same appearance and are provided with an opening on one side, that is, the first channel steel frame 21 and the second channel steel frame 31 are respectively provided with a U-shaped structure composed of three channel steels, and the side wall of the first channel steel frame 21 is fixedly connected with a square steel 23, and the square steel 23 is matched on the inner side of the second channel steel frame 31. The purpose of using the square steel 23 is that the square steel 23 can be supported by the second channel steel frame 31, that is, continuous support is provided for the outer side of the first channel steel frame 21, and further, in order to prevent the square steel 23 from shaking, a rubber pad can be provided inside the second channel steel frame 31 to fill the gap between the square steel 23 and the second channel steel frame 31. The interior of the first channel steel frame 21 is used to fix and support the photovoltaic panel 1. A detachable structure is adopted here. Compared with the traditional bracket, the photovoltaic panel 1 can be pulled out, which has the advantage of convenient installation, maintenance, repair and replacement. It should be noted that the support frame 3 in the present invention is fixed on the outer wall. For the convenience of maintenance, the support frame 3 is preferably fixedly connected to the balcony or the wall below the window.

[0020] A water trough 22 is provided at the lower part of the first channel steel frame 21. One of the factors affecting the power generation efficiency of the photovoltaic panel 1 is that the surface of the photovoltaic panel 1 is covered with dust and needs to be cleaned regularly. The photovoltaic panel 1 is installed on the outer wall. If it is cleaned directly, the water during the cleaning process will drip directly, affecting the pedestrians or green plants under the building. The water trough 22 is used here to receive the water during the tilting process and reduce the dripping of water. At the same time, the cleaning tools can be directly dipped in the water trough 22, which is more convenient to operate. The length of the water trough 22 is consistent with the width of the second channel steel frame 31. At the same time, the water trough 22 is set close to the first channel steel frame 21. The purpose of this setting is to fully receive the water that slides down from the photovoltaic panel 1.

[0021] Furthermore, the water in the water tank 22 can be completely evaporated under normal circumstances, so there is no need to consider the problem of water overflowing from the water tank 22. At the same time, it is also necessary to clean the interior of the water tank 22 regularly.

[0022] A baffle 24 is provided on one side of the opening of the first channel steel frame 21, and second bolts 210 are inserted at both ends of the baffle 24. The second bolts 210 and the square steel 23 are threadedly connected. After the photovoltaic panel 1 is pushed into the interior of the first channel steel frame 21, the baffle 24 is used to fix it at the opening of the first channel steel frame 21 to confine the photovoltaic panel 1 to the interior of the first channel steel frame 21.

[0023] The second channel steel frame 31 is tilted to improve lighting. The tilt angle of the second channel steel frame 31 can be adjusted according to the local latitude, and the tilt angle of the second channel steel frame 31 cannot affect the installation of the first channel steel frame 21. Furthermore, if the aesthetics of the exterior wall is to be improved, the second channel steel frame 31 can be vertically arranged, and a plurality of support rods 32 are fixedly connected to the back of the second channel steel frame 31. The support rods 32 are horizontally arranged, and the other end of the support rods 32 is fixedly connected to a mounting plate 33. A through hole 36 is arranged on the mounting plate 33, and expansion bolts can be used to pass through the through hole 36 to fix it to the exterior wall of the building.

[0024] The upper side wall of the second channel steel frame 31 is provided with a side plate 35, which is in the shape of a long strip, the lower part of the side plate 35 is fixed, and the upper part is bent, so that the side plate 35 can be easily pulled from the upper part of the side plate 35 and bent. It should be noted that after being released, the side plate 35 can also be restored to its original position. The upper part of the side plate 35 is fixedly connected with a buckle block 37, and the upper side of the buckle block 37 is inclined. When the first channel steel frame 21 is matched with the second channel steel frame 31, the square steel 23 is buckled by the buckle block. The inclined surface on the upper part of the block 37 can go over the snap-fit ​​block 37. The upper side wall of the square steel 23 is provided with a snap-fit ​​hole 29. One side of the snap-fit ​​block 37 fits in the snap-fit ​​hole 29. After the first channel steel frame 21 reaches the specified position, the snap-fit ​​block 37 extends into the snap-fit ​​hole 29, and the first channel steel frame 21 is limited. If it needs to be taken out again, two people are required to cooperate, pull the side panels 35 on both sides, separate the snap-fit ​​block 37 from the snap-fit ​​hole 39, and then the first channel steel frame 31 can be pulled out.

[0025] Reinforcing rods 34 are arranged between the support rods 32 to improve the structural strength of the support frame. The reinforcing rods 34 include vertically arranged and obliquely arranged rods to achieve the connection between the support rods 32, so that the support rods 32 become a whole.

[0026] A plurality of screws 27 are fixedly connected to the lower front part of the first channel steel frame 21, and the screws 27 penetrate the upper part of the water tank 22. The screws 27 are threadedly matched with nuts 28. That is, the water tank 22 can be removed by rotating and removing the nuts 28. According to the installation requirements, you can choose whether to install the water tank.

[0027] The back of the first channel steel frame 21 is threadedly matched and penetrated with a first bolt 26. When the photovoltaic panel 1 is inserted into the first channel steel frame 21, the first bolt 26 needs to be tightened so that the end of the first bolt 26 is tightly against the frame of the photovoltaic panel 1, thereby firmly fixing the photovoltaic panel 1 inside the first channel steel frame 21.

[0028] A handle 25 is fixedly connected to the middle of the upper end of the baffle 24, so as to facilitate the first channel steel frame 21 to be pulled out from the interior of the second channel steel frame 31.

[0029] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
