Abstract
Description
Technical Field
[0001] This invention relates to a waterproof device for busbar bridges and its installation method. Background Technology
[0002] In the field of high-voltage electrical equipment, busbars are a type of high-voltage power transmission and distribution device. With the continuous development of busbar trays, they have gradually moved from indoor installation to outdoor installation. However, due to the unpredictable outdoor weather, the waterproofing capabilities of busbar trays are extremely important, especially during rainy days. Currently, outdoor busbar trays generally use a welded structure. This structure can create small gaps at each connection point, posing a risk of leakage. Typically, waterproofing is achieved by sealing the bridge structure with a waterproof coating between sections.
[0003] While this method can provide waterproofing, the long-term exposure to the outdoors and the effects of sunlight, air oxidation, and corrosion result in a short aging cycle for the waterproof adhesive, which means the sealing of the cable tray cannot be adequately guaranteed. Summary of the Invention
[0004] The main objective of this invention is to provide a waterproof device for busbar bridges and its installation method. This device utilizes a purely mechanical structure to waterproof the busbar bridge. Furthermore, while the mechanical structure possesses excellent waterproofing performance, it is also easy to install. Moreover, the mechanical structure is not easily damaged after installation and can provide waterproofing for a longer period of time. In addition, this invention provides a simple and quick installation method.
[0005] The objective of this invention can be achieved by adopting the following technical solution:
[0006] A busbar bridge waterproofing device includes a busbar bridge cover plate and a busbar bridge base plate spaced apart vertically, with a busbar bridge body disposed between the busbar bridge cover plate and the busbar bridge base plate.
[0007] The outer side of the busbar bridge body is provided with rain shields and support plates distributed vertically, wherein the rain shields are inclined.
[0008] The top of the rain shield is attached to the outer wall of the busbar bridge body, and the bottom of the rain shield protrudes outward relative to the outer wall of the busbar bridge bottom plate below it.
[0009] The top of the support plate is provided with several support columns, and the side of the rain shield near the support plate has several grooves. The support columns are inserted into the corresponding grooves to provide inclined support for the rain shield.
[0010] The outer wall of the busbar bridge body is provided with a fixing groove, and an elastic clamp is engaged with the inner side of the fixing groove. A guide plate is provided at one end of the elastic clamp.
[0011] The top of the rain shield and the guide plate are distributed at intervals, and the bottom of the guide plate protrudes outward relative to the outer wall of the busbar bridge bottom plate below it.
[0012] Preferably, the elastic clamp is composed of an elastic bending section and two spaced vertical plates, with the elastic bending section disposed between the two vertical plates.
[0013] Preferably, the support plate includes a support portion, and both ends of the support portion are provided with connecting portions. An internal threaded hole is provided through the side of the connecting portion. The outer wall of the busbar bridge body is provided with another internal threaded hole that corresponds one-to-one with the internal threaded hole on the connecting portion. Fixing screws are inserted into the two corresponding internal threaded holes to fix the support plate to the outer wall of the busbar bridge body.
[0014] Preferably, there is a space between the support and the busbar bridge body, and the length of the space is equal to the length of the support, and the space is located directly below the rain shield.
[0015] Preferably, the busbar bridge cover plate, busbar bridge body, and busbar bridge bottom plate are all C-shaped plate structures.
[0016] Preferably, the outer walls of the busbar bridge cover plate and the busbar bridge bottom plate both protrude outward relative to the outer walls of the busbar bridge body, and the bottom end of the busbar bridge body is lower than the top sides of the left and right ends of the busbar bridge bottom plate.
[0017] Preferably, the top of the rain shield is located within the area enclosed by the busbar bridge cover plate and the busbar bridge bottom plate.
[0018] Preferably, the fixing groove includes a first vertical groove, and a second vertical groove is formed at the top of the first vertical groove. The thickness of the second vertical groove is less than the thickness of the first vertical groove. The elastic clamp is used to be embedded in the second vertical groove from top to bottom, so that the elastic clamp is compressed and the position of the elastic clamp is fixed.
[0019] A method for installing a waterproofing device for a busbar bridge, the method comprising the following steps:
[0020] Step 1: First, install and fix the busbar bridge cover plate, busbar bridge body and busbar bridge base plate with bolts, so that the outer walls of the two busbar bridge bodies are within the enclosure of the busbar bridge cover plate and busbar bridge base plate.
[0021] Step 2: Then, use bolts to install and fix the connecting part and the busbar bridge body. After the support plate is installed in the correct position, leave a gap between the support part and the busbar bridge body.

[0033] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0034] like Figures 1-4 As shown, the busbar bridge waterproofing device provided in this embodiment includes a busbar bridge cover plate 1 and a busbar bridge bottom plate 3 spaced vertically. A busbar bridge body 2 is disposed between the busbar bridge cover plate 1 and the busbar bridge bottom plate 3. The busbar bridge cover plate 1, the busbar bridge body 2, and the busbar bridge bottom plate 3 are all C-shaped plate structures. There are two busbar bridge bodies 2, which are symmetrically arranged from left to right. When the busbar bridge cover plate 1 and the busbar bridge bottom plate 3 are spaced vertically, they can form a surrounding ring, that is, a frame structure. Figure 1 As shown, both the left and right sides of the frame structure are exposed.
[0035] The outer side of the busbar bridge body 2 is provided with rain shields 4 and support plates 5 distributed vertically, wherein the rain shields 4 are inclined and the support plates 5 are horizontal.
[0036] The top of the rain shield 4 is attached to the outer wall of the busbar bridge body 2. It is only attached to the outer wall of the busbar bridge body 2, and the two are not connected by means such as welding. The rain shield 4 is only tilted and overlapped above the support plate 5, which effectively improves the installation efficiency of the rain shield 4. The bottom end of the rain shield 4 protrudes outward relative to the outer wall of the busbar bridge bottom plate 3 below it, ensuring that the rainwater falling on the rain shield 4 can flow outward along the bottom end of the rain shield 4 and will not fall at the connection between the busbar bridge body 2 and the busbar bridge bottom plate 3.
[0037] The top of the support plate 5 is provided with several support columns 6, and the side of the rain shield 4 near the support plate 5 is provided with several grooves 9. The support columns 6 are inserted into the corresponding grooves 9 to provide inclined support for the rain shield 4, which facilitates the installation of the rain shield 4. That is, the installation steps only require one step: match the grooves 9 and the support columns 6 one by one. There is no need for welding, bolt fixing or other methods. Moreover, relying on the structure and gravity of the rain shield 4 itself, it is not easy to detach from the busbar bridge body 2 when used in the external environment.
[0038] The outer wall of the busbar bridge body 2 is provided with a fixing groove 7. An elastic clamping plate 801 is snapped into the inner side of the fixing groove 7. A guide plate 802 is provided at one end of the elastic clamping plate 801. The guide plate 802 is also inclined. The fixing groove 7 includes a first vertical groove, the thickness of which is less than the thickness of the busbar bridge body 2. A second vertical groove is opened at the top of the first vertical groove, the thickness of which is less than the thickness of the first vertical groove. The elastic clamping plate 801 is used to be embedded into the second vertical groove from top to bottom, so that the elastic clamping plate 801 is compressed and the elastic clamping plate is subjected to pressure. The position of 801 is fixed, and the elastic clamp 801 can be directly moved horizontally into the first vertical groove. Then, the elastic clamp 801 is moved upward so that it is inserted into the second vertical groove. The elastic clamp 801 is composed of an elastic bending part and two spaced vertical plates. The elastic bending part is located between the two vertical plates. When the elastic clamp 801 is slowly inserted into the second vertical groove, the distance between the two vertical plates gradually decreases until the elastic clamp 801 is almost completely submerged in the second vertical groove, and then the position of the elastic clamp 801 is completely fixed.
[0039] The top of the rain shield 4 and the guide plate 802 are distributed vertically at intervals, and the bottom of the guide plate 802 protrudes outward relative to the outer side wall of the busbar bridge bottom plate 3 below it. That is, the bottom of the guide plate 802 in the inclined state extends beyond the right end face of the busbar bridge bottom plate 3, ensuring that the guide plate 802 can guide the rainwater on it to the outside of the busbar bridge. The vertical distance between the bottom of the rain shield 4 and the top side of the end of the busbar bridge bottom plate 3 can be between 2 and 3 cm, and the vertical distance between the bottom of the guide plate 802 and the top side of the end of the busbar bridge bottom plate 3 can be between 0.5 and 1.5 cm. Both are close to the end of the busbar bridge bottom plate 3, which can effectively prevent rainwater from seeping in from the connection between the busbar bridge body and the bottom plate.
[0040] In this embodiment, as Figure 1As shown, the support plate 5 includes a support portion 502, with connecting portions 501 at both ends. An internally threaded hole passes through the side of each connecting portion 501. The outer wall of the busbar bridge body 2 has another internally threaded hole corresponding to the internally threaded hole on the connecting portion 501. Fixing screws are inserted into the two corresponding internally threaded holes to fix the support plate 5 to the outer wall of the busbar bridge body 2. A space is left between the support portion 502 and the busbar bridge body 2, and the length of this space is equal to the length of the support portion 502. This space is located directly below the rain shield 4, ensuring the support plate 5... This will not affect the rainwater falling from the gap between the busbar bridge body 2 and the rain shield 4 onto the guide plate 802, which provides a second waterproofing effect for the busbar bridge. Because no other connection measures such as welding or sealing materials are used between the water shield 4 and the busbar bridge body 2 for the convenience of installation, there is a gap between the water shield 4 and the busbar bridge body 2. The guide plate 802 can ensure that the rainwater flowing from the gap to the connection between the busbar bridge body 2 and the busbar bridge bottom plate 3 will first flow onto the guide plate 802, ensuring that no rainwater enters the interior of the busbar bridge.
[0041] In this embodiment, as Figure 1 As shown, the outer walls of the busbar bridge cover plate 1 and the busbar bridge base plate 3 protrude outward relative to the outer wall of the busbar bridge body 2. The bottom end of the busbar bridge body 2 is lower than the top side of the left and right ends of the busbar bridge base plate 3. In order to facilitate the installation of the busbar bridge cover plate 1, the bridge body 2 and the base plate 3, the three can be fixed together by bolts or other means. For example, the bottom end of the bridge body 2 is fixed to the left and right ends of the base plate 3 by bolts or other fasteners, which is easier and simpler than welding.
[0042] In this embodiment, as Figure 1 As shown, the top of the rain shield 4 is located within the area enclosed by the busbar bridge cover plate 1 and the busbar bridge bottom plate 3, making the structure reasonable and ensuring that the rain shield 4 can play a role in blocking rain.
[0043] A method for installing a waterproof device for a busbar bridge, the method comprising the following steps:
[0044] Step 1: First, install and fix the busbar bridge cover plate 1, busbar bridge body 2 and busbar bridge bottom plate 3 with bolts, so that the outer walls of the two busbar bridge bodies 2 are within the enclosure of the busbar bridge cover plate 1 and the busbar bridge bottom plate 3.
[0045] Step 2: Then, install and fix the connecting part 501 and the busbar bridge body 2 with bolts. After the support plate 5 is installed, a gap is left between the support part 502 and the busbar bridge body 2.
[0046] Step 3: Insert the elastic clamp 801 into the first vertical groove and then move it upward to move the elastic clamp 801 into the second vertical groove until the elastic clamp 801 is in a fixed state.
[0047] Step 4: Place the rain shield 4 directly on top of the support plate 5, aligning the groove 9 on the bottom side of the rain shield 4 with the support column 6 on the support part 502. The support column 6 supports and limits the rain shield 4, ensuring that the rain shield 4 is tilted on the outside of the busbar bridge body 2, and at this time, the bottom end of the rain shield 4 protrudes outward relative to the outer wall of the busbar bridge bottom plate 3.
[0048] In summary, the installation method provided in this embodiment is simple to operate, requires no welding or other procedures, effectively improves the installation efficiency of the busbar bridge waterproofing device, and has excellent waterproofing performance after being neatly installed. Moreover, as a purely mechanical waterproofing device, its service life is not affected by welding, waterproofing adhesive, etc., and its service life can be greatly improved.
[0049] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
