Description

Technical Field

[0001] The utility model belongs to the technical field of heavy-duty busbars, and particularly relates to a safe heavy-duty busbar. Background Art

[0002] Modern high-rise buildings and large workshops require huge amounts of electrical energy. Facing the hundreds or thousands of amperes of strong current required by this huge load, a safe and reliable current conduction device needs to be selected. The busbar is a highly efficient current distribution device for transporting current, especially meeting the needs of more and more high-rise buildings and large-scale factories for economical and reasonable wiring.

[0003] Chinese Patent with the publication number of "CN205846647U" discloses a safe heavy-duty busbar. Busbar fixing devices are provided on both the busbar cover plate and the busbar bottom plate. The number of busbar fixing devices is two, which are respectively located at the center position of the bottom of the busbar cover plate and the center position of the top of the busbar bottom plate. The two busbar fixing devices are symmetrically arranged up and down. There are nine fixing positions on the busbar fixing device, and fixing partitions are provided between the fixing positions.

[0004] However, there are still some deficiencies in this busbar. Since the busbars are installed inside the busbar, when the busbar is closed, the heat dissipation capacity of the busbar itself will be greatly reduced. When the busbars are operating, they will release a certain amount of heat, and these heats will be discharged into the busbar. Due to the low heat dissipation performance of the busbar itself, the heat released by the busbars cannot be well dissipated, which will in turn affect the service life of the busbars themselves. Content of the Utility Model

[0005] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide a safe heavy-duty busbar to solve the problems raised in the above background art.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A safety type heavy-duty busbar trunking, comprising a busbar trunking body. A first clamping plate is clamped at the inner bottom end of the busbar trunking body. A busbar is installed at the inner bottom end of the busbar trunking body, and the busbar is located inside the first clamping plate. A top cover is clamped at the top end of the busbar trunking body, and the top cover covers the top end of the busbar trunking body. A second clamping plate matched with the first clamping plate is fixedly connected to the bottom end of the top cover. The position of the first clamping plate is symmetrical to the position of the second clamping plate. A ventilation opening is provided at the bottom end of the busbar trunking body, and the ventilation opening communicates with the inside of the busbar trunking body. A dust-proof plate is slidably connected to the inner wall of the ventilation opening. A chute matched with the dust-proof plate is provided on the inner wall of the ventilation opening, and the dust-proof plate is slidably connected to the inner wall of the ventilation opening through the chute. A fixing block is fixedly connected to the bottom end of the dust-proof plate, and the top end of the fixing block is attached to the bottom end of the busbar trunking body. A screw hole is provided at the bottom end of the fixing block, and the screw hole penetrates through the fixing block and the top end of the busbar trunking body. A bolt is threadedly connected to the inside of the screw hole, and the top end of the bolt is threadedly connected to the inside of the busbar trunking body through the screw hole. By installing the top cover, the busbar can be completely wrapped, thereby achieving a good protection effect. The mutual fitting of the first clamping plate and the second clamping plate can effectively divide the busbar. Due to the opening of the ventilation opening, effective ventilation and heat dissipation can be carried out inside the busbar trunking body. The dust-proof plate can protect the inside of the ventilation opening while not hindering the heat dissipation of the ventilation opening, and can also prevent a large amount of dust and pollutants in the air from entering the inside of the busbar trunking body, thereby achieving a good ventilation and heat dissipation effect.

[0008] As a preferred technical solution, an insertion block is fixedly connected to the bottom end of the top cover, and a slot matched with the insertion block is provided at the top end of the busbar trunking body. The insertion block is inserted into the inside of the slot. By inserting the insertion block, the position of the shell cover can be effectively limited, thereby improving the accuracy of fixing the position of the shell cover.

[0009] As a preferred technical solution, a bayonet is provided at the top end of the top cover, and a first clamping block is clamped inside the bayonet. A second clamping block is fixedly connected to the outer wall of the first clamping block, and a convex block is fixedly connected to the top end of the first clamping block. The shape of the convex block is an inverted cone. A second clamping slot matched with the first clamping block and the second clamping block is provided at the top end of the busbar trunking body. A circular groove is provided inside the second clamping slot, and the first clamping block and the second clamping block are clamped inside the circular groove through the second clamping slot. By providing the second clamping slot, it is beneficial to insert the first clamping block and the second clamping block into the circular groove. After entering the circular groove, slightly rotate the first clamping block through the grabbing point given by the convex block, so that the second clamping block and the second clamping slot are not symmetrical to each other, thereby avoiding the first clamping block from being ejected. While avoiding the top cover from falling off, it is also more beneficial for the user to disassemble and assemble the top cover later.

[0010] As a preferred technical solution, a snap spring matching the first clamping block and the second clamping block is installed inside the circular groove. The bottom ends of the first clamping block and the second clamping block are clamped to the top end of the snap spring. Through the installation of the snap spring, the snap spring can perform secondary clamping and fixing on the second clamping block clamped into the circular groove, thereby being able to prevent the second clamping block from deviating in angle, and thus effectively improving the clamping stability of the position of the first clamping block.

[0011] As a preferred technical solution, a rectangular opening is provided at the top end of the top cover. The rectangular opening communicates with the inside of the busbar trough body. A transparent glass is fixedly connected to the inside of the rectangular opening. The transparent glass covers the inside of the rectangular opening. The position of the transparent glass is symmetrical to the position of the busbar body. Through the opening of the rectangular opening, the user can directly view the inside of the busbar trough body through the transparent glass, so it is beneficial for the user to observe the position of the busbar body at all times.

[0012] As a preferred technical solution, a first card slot matching the first card board is provided at the bottom end inside the busbar trough body. The first card board is clamped to the bottom end inside the busbar trough body through the first card slot. The opening of the first card slot facilitates the user to disassemble and assemble the first card board.

[0013] As a preferred technical solution, a rubber pad is fixedly connected to the bottom end of the second card board. The rubber pad covers the bottom end of the second card board. The position of the bottom end of the rubber pad is in contact with the position of the top end of the first card board. Through the fixation of the rubber pad, the rubber pad has good anti-slip ability and rubber shock absorption ability, and at the same time can also make the first card board and the second card board fit more closely.

[0014] In summary, the present utility model mainly has the following beneficial effects:

[0015] First, when in use, the mutual fitting of the first card board and the second card board can effectively divide the busbar body. Due to the opening of the ventilation openings, effective ventilation and heat dissipation can be carried out inside the busbar trough body. The dust-proof board can protect the inside of the ventilation openings while not interfering with the heat dissipation of the ventilation openings, and at the same time can also prevent a large amount of dust and pollutants in the air from entering the inside of the busbar trough body, thereby achieving a good ventilation and heat dissipation effect. While solving the problem that the busbar trough body is not easy to dissipate heat, the service life of the busbar body itself is effectively improved;

[0016] Second, due to the existence of the insertion block, the insertion of the insertion block can effectively limit the position of the top cover, thereby improving the accuracy of fixing the position of the top cover. After the insertion block is inserted, the first clamping block and the second clamping block are clamped into the circular groove through the second clamping groove. Then, the first clamping block is slightly rotated through the convex block, and then the position of the second clamping block is clamped again through the clamping spring, thereby avoiding the angular deviation of the second clamping block. At the same time, the positions of the second clamping block and the second clamping groove cannot be symmetrical, which can effectively prevent the first clamping block from being ejected. While preventing the top cover from falling, it is also more conducive to the user to disassemble and assemble the top cover later. BRIEF DESCRIPTION OF THE DRAWINGS

The first clamping plate 4 and the second clamping plate 10 can effectively divide each bus bar 2. Due to the opening of the ventilation opening 19, effective ventilation and heat dissipation can be carried out inside the busway body 1. The dust - proof plate 21 can protect the inside of the ventilation opening 19 while not interfering with the heat dissipation of the ventilation opening 19, and at the same time can also prevent a large amount of dust and pollutants in the air from entering the inside of the busway body 1, thereby being able to achieve a good ventilation and heat dissipation effect and effectively improve the service life of the bus bar 2 itself.

[0027] Reference Figure 1 And Figure 2 And Figure 5 , An insertion block 9 is fixedly connected to the bottom end of the top cover 6. A slot 5 matched with the insertion block 9 is opened at the top end of the busway body 1. The insertion block 9 is inserted into the inside of the slot 5.

At the same time, the positions of the second clamping block 14 and the second clamping groove 16 cannot be symmetrical with each other, which can effectively prevent the first clamping block 13 from being ejected. While preventing the top cover 6 from falling off, it is also more convenient for the user to disassemble and assemble the top cover 6 later.

A transparent glass 8 is fixedly connected to the inner side of the rectangular opening 7, and the transparent glass 8 covers the inner side of the rectangular opening 7. The position of the transparent glass 8 is symmetrical with the position of the bus body 2. Due to the opening of the rectangular opening 7, the user can directly view the inner side of the bus trough body 1 through the transparent glass 8 without opening the top cover 6, which is beneficial for the user to observe the installation point of the bus body 2 at all times, thereby effectively improving the safety of the installation position of the bus body 2.

[0030] refer to Figure 1 and Figure 4 A first card slot 3 matching the first card plate 4 is provided at the inner bottom end of the bus trough body 1. The first card plate 4 is connected to the inner bottom end of the bus trough body 1 through the first card slot 3.

[0031] refer to Figure 2, a rubber pad 11 is fixedly connected to the bottom end of the second clamping plate 10. The rubber pad 11 covers the bottom end of the second clamping plate 10. The position of the bottom end of the rubber pad 11 is in contact with the position of the top end of the first clamping plate 4. Due to the existence of the rubber pad 11, which is a rubber product, it has good rubber anti-slip ability and rubber shock-absorbing ability. At the same time, it can also make the first clamping plate 4 and the second clamping plate 10 fit more tightly, thereby effectively improving the stability of the fit between the first clamping plate 4 and the second clamping plate 10.

[0032] Principle of use and advantages: When using the busbar trough body 1, the top cover 6 is clamped and fixed. The top cover 6 and the busbar trough body 1 can completely wrap the busbar body 2, thereby being able to provide good protection for the busbar body 2. After the top cover 6 is fixed, the first clamping plate 4 and the second clamping plate 10 will fit together accordingly. The first clamping plate 4 and the second clamping plate 10 can effectively divide each busbar body 2. Due to the opening of the ventilation openings 19, effective ventilation and heat dissipation can be carried out inside the busbar trough body 1. The dust-proof plate 21 can protect the inside of the ventilation openings 19 while not hindering the heat dissipation of the ventilation openings 19, and at the same time can also prevent a large amount of dust and pollutants in the air from entering the inside of the busbar trough body 1, thereby achieving a good ventilation and heat dissipation effect and effectively improving the service life of the busbar body 2 itself. Due to the existence of the insertion block 9, when the insertion block 9 is inserted into the insertion slot 5, the position of the top cover 6 can be effectively limited, thereby improving the accuracy of the position fixation of the top cover 6. After the insertion block 9 is inserted, the first clamping block 13 and the second clamping block 14 are snapped into the circular groove 17 through the second clamping groove 16. Then, the first clamping block 13 is slightly rotated through the convex block 15, and then the position of the second clamping block 14 is secondarily clamped through the clamping spring 18, thereby being able to prevent the second clamping block 14 from deviating in angle. At the same time, the positions of the second clamping block 14 and the second clamping groove 16 are not symmetric with each other, which can effectively prevent the first clamping block 13 from being ejected. While preventing the top cover 6 from falling, it is also more conducive to the user to disassemble and assemble the top cover 6 later. Due to the opening of the rectangular opening 7, the user can directly view the inside of the busbar trough body 1 through the transparent glass 8 without opening the top cover 6, thereby facilitating the user to always observe the installation points of the busbar body 2, and thus effectively improving the safety of the installation position of the busbar body 2. Due to the opening of the first clamping groove 3, the position of the first clamping plate 4 can be effectively clamped and limited, thereby preventing the first clamping plate 4 from shifting, and at the same time facilitating the user to disassemble the first clamping plate 4 later for individual maintenance.
