Description

Technical Field

[0001] The present invention relates to a busbar heat dissipation protection structure and an installation method thereof. Background Art

[0002] As a key device in the field of power transmission, busbars are widely used in various buildings, industrial plants, substations and other places. It undertakes the important tasks of collecting, distributing and transmitting electric energy, and is one of the core components to ensure the stable operation of the power system.

[0003] The existing busbars are restricted by the wall after installation and cannot install heat sinks. For example, on a right-angled wall, heat sinks cannot be installed on one side, resulting in low heat dissipation efficiency. To solve this problem, only by setting the busbar away from the wall, but this causes waste of space. At the same time, the contact heads of the existing busbars are difficult to replace, and usually the entire busbar needs to be removed, causing trouble in maintenance.

[0004] Therefore, how to design a busbar that can be compactly installed on the wall and at the same time can facilitate the replacement of the contact head is a problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art, and provide a busbar heat dissipation protection structure and an installation method. By respectively arranging a chute on each of the four sides of the main body, and then designing a heat dissipation fin that can be engaged with the chute in a snap-fit manner, so that the main body can be closely arranged against the cavity when installed on a right-angled wall without affecting the installation of the heat dissipation fins. At the same time, by designing a detachable contact head, it is convenient to replace the contact head. These objects of the present invention are achieved as follows:

[0006] On the one hand, the present invention provides a busbar heat dissipation protection structure, including a main body, a heat dissipation fin plate, a fixing sleeve, a first contact device and a second contact device. The main body is integrally in a cuboid shape. A chute is provided on each of the upper part, lower part, left part and right part of the main body. Two inclined chutes are provided at the front end of the main body, and two inclined chutes are provided at the rear end of the main body. The heat dissipation fin plate is installed on a first mounting plate. The length of the first mounting plate is equal to the length of the main body. Three fixing members are installed on the first mounting plate. The fixing members are equidistantly distributed along the long axis direction of the first mounting plate. After the first mounting plate is attached to the main body, the fixing members are engaged with the chutes in a snap-fit manner. The first contact device includes a second mounting plate, an inclined plug and a contact head. The second contact device includes a second mounting plate, an inclined plug and a contact head. The first contact device and the second contact device are respectively arranged at the front end and the rear end of the main body. The inclined plug is installed on one side of the second mounting plate, and the contact head is installed on the other side of the second mounting plate. After the second mounting plate is attached to the main body, the inclined plug is engaged with the inclined chute in a snap-fit manner.

[0007] Furthermore, the sliding groove extends along the length direction of the main body. The depth of the sliding groove is 6 cm. The sliding groove includes a narrow part and a wide part. The narrow part penetrates through the outer surface of the main body and extends into the main body. The wide part is arranged at the bottom end of the narrow part. The width of the wide part is four times that of the narrow part. The width of the narrow part is 3 cm, and the width of the wide part is 12 cm.

[0008] Furthermore, the fixing member includes a spring and reverse teeth. The spring is installed inside the fixing member. The reverse teeth can protrude or retract on the fixing member. One end of the spring abuts and is fixed against the inner wall of the fixing member, and the other end of the spring abuts and is fixed against the bottom of the reverse teeth. An inclined surface is provided on the upper part of the reverse teeth, and the angle of the inclined surface is 45 degrees. There are two reverse teeth, which are oppositely arranged on the fixing member. The length of each reverse tooth is 4 cm, and the height of each reverse tooth is 3 cm. There are four springs.

[0009] Furthermore, the angle of the inclined groove is 45 degrees, the depth of the inclined groove is 6 cm, and there are two inclined grooves on each surface of the main body.

[0010] Furthermore, there are 27 heat dissipation fin plates, and the shape of the heat dissipation fin plates is rectangular.

[0011] Furthermore, the contact head of the first contact device of the main body and the contact head of the second contact device of another main body are fixedly installed through a fixing sleeve.

[0012] Furthermore, the fixing sleeve has an opening and closing mechanism. The material of the fixing sleeve is stainless steel, and a rubber sleeve is provided on the outside of the fixing sleeve.

[0013] On the other hand, the present invention proposes a method for installing a busway, including: fixing the main body on the wall surface; determining the preset installation surface of the heat dissipation fin plates according to the wall structure; clamping the fixing member in the sliding groove and fixing the heat dissipation fin plates on the preset installation surface; fixing another main body on the wall surface and corresponding to the previous main body, and installing the heat dissipation fin plates of another main body; inserting the inclined plug into the inclined groove to install the first contact device and the second contact device of each main body, and then using the fixing sleeve to fixedly install the contact heads of adjacent main bodies.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the fitting and clamping method of the inclined plug and the inclined groove on the main body, when the contact head needs to be replaced, only the fixing sleeve needs to be removed and the inclined plug is pulled out from the inclined groove, and then the contact head can be conveniently replaced, which greatly improves the maintenance efficiency, reduces the power outage time caused by maintenance, and ensures the continuity of power supply;

[0015] By providing sliding grooves on four sides of the main body and cooperating with the heat dissipation fins that can be snap-connected, when the busbar trunking is installed on complex wall structures such as right-angled walls, it can be closely attached to the wall, effectively utilizing the installation space and making the installation more compact.

[0033] In this embodiment, the chute 2 extends along the length direction of the main body 1. The depth of the chute 2 is 10 cm. The chute 2 includes a narrow part 6 and a wide part 5.

[0034] In a possible usage scenario, in the corridor area of a commercial complex, due to limited space and the need to install a large number of pipelines, the traditional installation method of bus ducts is difficult to implement because the installation of heat sinks is restricted. With the bus duct heat dissipation and protection structure of the present invention, the installer first tightly fixes the cuboid main body 1 on the wall surface of the corridor. At the right-angle corner, taking advantage of the fact that the four side surfaces of the main body 1 are all provided with chutes 2, the installation surface of the heat dissipation fin 3 on the side is determined according to the wall structure. The fixing member 7 on the first mounting plate 4 has a spring 10 inside it, which pushes the reverse tooth 9 with a 45-degree inclined surface 8. When it fits and engages with the chute 2 of the main body 1, the reverse tooth 9 is pressed into the fixing member 7 under the action of the inclined surface 8, and then pops out under the action of the spring 10 after entering the wide part 5, firmly clamping in the wide part 5, thus firmly fixing the heat dissipation fin 3 on the preset installation surface. Here, the depth of the chute 2 of the main body 1 is 6 cm, the narrow part 6 is 3 cm wide, the wide part 5 is 12 cm wide, the length of the reverse tooth 9 is 4 cm, and the height is 3 cm, which is adapted to the size of the chute 2 to ensure firm installation. 27 rectangular heat dissipation fins 3 are installed in this area, increasing the heat dissipation area and effectively dissipating the heat generated during the operation of the bus duct. The main bodies 1 of the bus ducts in different areas are connected through the first contact device 13 and the second contact device 16. Between different floors of the shopping mall, the inclined plugs 15 of the first contact device 13 at the front end and the second contact device 16 at the rear end of the main body 1 are accurately inserted into the inclined slots 17 with the same angle and a depth of 6 cm on the main body 1 at a 45-degree angle, and the fitting and engagement are completed for installation. Then, a stainless steel fixing sleeve 14 with an opening and closing mechanism is used to fixedly install the contact heads 11 of adjacent main bodies 1. The external rubber sleeve plays a role in insulation and increasing friction, ensuring a firm connection. During daily maintenance, if it is found that a certain contact head 11 has a problem, the maintenance personnel do not need to disassemble the entire bus duct. They only need to open the fixing sleeve 14 and pull out the inclined plug 15 from the inclined slot 17, and then they can complete the replacement of the contact head 11 in a short time, greatly improving the maintenance efficiency and ensuring the continuity of the power supply in the commercial complex, and avoiding inconveniences to merchants and customers caused by power outages.

[0035] It should be noted that the structure of the fixing sleeve 14 is an existing general technical means, such as a structure similar to handcuffs and a hinge structure. In this solution, they are all opening and closing structures with hinges.

[0036] On the other hand, the present invention proposes a method for installing a bus duct, including: S1, fixing the main body 1 on the wall surface; S2, determining the preset installation surface of the heat dissipation fin 3 according to the wall structure; S3, the fixing member 7 is clamped in the chute 2 to fix the heat dissipation fin 3 on the preset installation surface; S4, fixing another main body 1 on the wall surface and corresponding to the previous main body 1, and installing the heat dissipation fin 3 of the other main body 1; S5, inserting the inclined plug 15 into the inclined slot 17, thereby installing the first contact device 13 and the second contact device 16 of each main body 1, and then using the fixing sleeve 14 to fixedly install the contact heads 11 of adjacent main bodies 1.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
