[0025] Referring to Figures 1 - 3 , a busbar groove sealing structure of the present utility model is shown, including a busbar groove body 10 and a connection housing 20 sleeved at the end of the busbar groove body 10. A sealing member 21 is provided at one end of the connection housing 20 facing the adjacent busbar groove body 10.

[0026] Heat dissipation holes 22 are formed on opposite sides of the connection housing 20, and the heat dissipation holes 22 communicate with the inside of the busbar groove body 10. A driving assembly and a sealing clamp are provided on the outer wall of the connection housing 20. The sealing clamp clamps the outer wall of the connection housing 20 and is respectively opposite to the two heat dissipation holes 22. A sealing plug 35 is provided at a position on the inner wall of the sealing clamp opposite to the heat dissipation hole 22, and the sealing plug 35 is adapted to the heat dissipation hole 22. The driving assembly is connected to the sealing clamp and is used to drive the sealing clamp to move relatively.

[0027] The busbar groove body 10 is provided with a temperature sensor, and the temperature sensor is electrically connected to the driving assembly. When the temperature sensor detects that the temperature exceeds the set value, the driving assembly drives the sealing clamp to move away from each other, and the sealing plug 35 is separated from the heat dissipation hole 22.

[0028] In an embodiment of the present application, through a busbar trunking body 10 and a connection housing 20 sleeved at the end of the busbar trunking body 10, a sealing member 21 is provided at one end of the connection housing 20 facing the adjacent busbar trunking body 10; heat dissipation holes 22 are formed on opposite sides of the connection housing 20, and the heat dissipation holes 22 communicate with the inside of the busbar trunking body 10; a driving assembly and a sealing fixture are provided on the outer wall of the connection housing 20, the sealing fixture clamps on the outer wall of the connection housing 20 and is respectively opposite to the two heat dissipation holes 22, a sealing plug 35 is provided at a position on the inner wall of the sealing fixture opposite to the heat dissipation holes 22, and the sealing plug 35 is adapted to the heat dissipation holes 22; the driving assembly is connected to the sealing fixture and is used to drive the sealing fixture to move relatively; the busbar trunking body 10 is provided with a temperature sensor, and the temperature sensor is electrically connected to the driving assembly; when the temperature sensor detects that the temperature exceeds a set value, the driving assembly drives the sealing fixture to move away from each other, and the sealing plug 35 is separated from the heat dissipation holes 22. The adjacent two busbar trunking bodies 10 are docked through the connection housing 20, and the connection part is sealed through the sealing member 21; by providing a driving assembly and a sealing fixture on the outer wall of the connection housing 20, in a normal state, the sealing fixture clamps on the outside of the connection housing 20, and the sealing plug 35 seals the heat dissipation holes 22. When the temperature of the busbar trunking body 10 is too high, the driving assembly drives the sealing fixture to move away from each other, so that the sealing plug 35 is separated from the heat dissipation holes 22, thereby dissipating heat from the busbar trunking body 10 through the heat dissipation holes 22. The present application can improve the sealing performance of the busbar trunking body 10 and can effectively dissipate heat from the busbar trunking body 10.

[0029] Next, a busbar trunking sealing structure in this exemplary embodiment will be further described.

[0030] In an embodiment of the present application, a sealing member 21 is provided at one end of the connection housing 20 facing the adjacent busbar trunking body 10. Generally, connection housings 20 are respectively provided at both ends of the busbar trunking body 10 for connecting with the connection housings 20 adjacent to both ends and sealing the connection part of the busbar trunking body 10 inside.

[0031] As an example, the sealing member 21 includes an annular sealing strip / sealing groove, and the sealing strip / sealing groove is adapted to the sealing groove / sealing strip of the adjacent connection housing 20. That is, when the sealing member 21 of one connection housing 20 is a sealing strip, the sealing member 21 of the connection housing 20 docked with it is a sealing groove. After the sealing strip and the sealing groove are adaptively connected, they can effectively seal the connection part. When connecting, the two connection housings 20 are abutted, and the sealing strip is embedded in the sealing groove. Among them, the sealing strip is made of silica gel material, which can improve the sealing performance.

[0032] As an example, the seal 21 further includes an annular male connector / female connector, and the male connector / female connector is respectively adapted to the female connector / male connector of the adjacent connection housing 20. That is, when the seal 21 of one connection housing 20 further includes a male connector, the seal 21 of the connection housing 20 docked with it further includes a female connector. After the male connector and the female connector are adaptively connected, they can connect the two connection housings 20 and prevent accidental detachment. Specifically, the above male connector and female connector can be a clamping block and a clamping groove respectively, and are connected by clamping, and a certain external force needs to be applied to separate and disassemble them.

[0033] As an example, the sealing strip / sealing groove is located inside the male connector / female connector. In addition to playing a connecting role, the connector can also serve as the first layer of seal on the outer layer. The sealing strip and the sealing groove play the second layer of seal on the inner layer, which can effectively improve the sealing effect.

[0034] In the embodiment of the present application, heat dissipation holes 22 are provided on opposite sides of the connection housing 20, and the heat dissipation holes 22 are internally communicated with the busbar trunk body 10. Specifically, through holes can be provided on the side wall of the busbar trunk body 10, and the through holes are communicated with the heat dissipation holes 22, so that the heat inside the busbar trunk body 10 can be discharged through the heat dissipation holes 22, improving the heat dissipation performance. A driving assembly and a sealing clamp are provided on the outer wall of the connection housing 20. The sealing clamp clamps the outer wall of the connection housing 20 and is respectively opposite to the two heat dissipation holes 22. A sealing plug 35 is provided at a position on the inner wall of the sealing clamp opposite to the heat dissipation holes 22, and the sealing plug 35 is adapted to the heat dissipation holes 22; the driving assembly is connected to the sealing clamp and is used to drive the sealing clamp to move relatively. By driving the sealing clamp to move towards or away from each other, the sealing plug 35 of the sealing clamp and the heat dissipation holes 22 are closed or separated, realizing the opening and closing of the heat dissipation holes 22. The busbar trunk body 10 is provided with a temperature sensor, and the temperature sensor is electrically connected to the driving assembly; when the temperature sensor detects that the temperature exceeds the set value, the driving assembly drives the sealing clamp to move away from each other, and the sealing plug 35 is separated from the heat dissipation holes 22. By detecting the temperature change through the temperature sensor, the movement of the sealing clamp is automatically controlled, realizing the automatic opening and closing of the heat dissipation holes 22, without manual operation and with high efficiency. Moreover, the clamping force of the sealing clamp can improve the sealing performance of the sealing plug 35 to the heat dissipation holes 22, and can effectively protect the busbar trunk body 10 when heat dissipation is not required.

[0035] As an example, the sealing fixture includes two L-shaped clamping plates 31 which are oppositely arranged on the outer wall of the connecting housing 20. The clamping plate 31 includes a horizontal plate and a vertical plate which are integrally connected, and the sealing plug 35 is arranged on the inner wall of the vertical plate. When the two clamping plates 31 move towards each other, the distance between the clamping plates 31 becomes smaller, and the sealing plug 35 enters the heat dissipation hole 22 to seal it. Under the clamping force of the clamping plate 31, the vertical plate is tightly attached to the outer wall of the connecting housing 20, and the sealing effect is good.

[0036] As an example, the driving assembly includes a controller, a driving member 32 and two lead screws 33. The controller is electrically connected to the driving member 32, and the temperature sensor is also electrically connected to the controller to send the detected data to the controller, and the opening and closing of the driving member 32 is controlled by the controller. The two lead screws 33 are respectively arranged on opposite sides of the driving member 32 and are respectively connected to two output ends of the driving member 32. Among them, the two lead screws 33 have opposite helix directions; the horizontal plate is screwed to the lead screw 33. Specifically, the driving member 32 includes a driving motor and a double-shaft reduction gear. The output end of the driving motor is connected to the input end of the double-shaft reduction gear. That is, by setting the driving member 32 with two output ends, the two lead screws 33 are synchronously driven to rotate, and the two lead screws 33 have opposite helix directions, so as to drive the two clamping plates 31 to move towards or away from each other, realizing clamping or opening.

[0037] Further, the driving motor, the controller and the reduction gear are integrated in a protective box 37. The protective box 37 is fixed outside the connecting housing 20, which can play a role in waterproofing and dustproofing for the above structure and extend its service life. The driving assembly can be arranged at the top or bottom of the connecting housing 20 according to the installation situation. When there is no waterproof device at the top, it is preferably arranged at the bottom of the connecting housing 20.

[0038] As an example, a blocking block 34 is arranged at one end of the lead screw 33 away from the driving member 32. The blocking block 34 is arranged at the end of the lead screw 33 to prevent the horizontal plate from accidentally separating from the lead screw 33 and improve the stability of the clamping plate 31.

[0039] As an example, a heat dissipation fan is arranged on the inner wall of the busbar trunking body 10, and the heat dissipation fan is electrically connected to the controller. By setting the heat dissipation fan, when the detected temperature is too high, the air flow inside the busbar trunking body 10 can be assisted and quickly discharged from the heat dissipation hole 22, improving the heat dissipation effect and efficiency.

[0040] As an example, a sealing disc 36 is provided on one side of the sealing plug 35 facing the heat dissipation hole 22. The sealing disc 36 is inclined towards the vertical plate, and the maximum diameter width of the sealing disc 36 is greater than the maximum diameter width of the sealing plug 35. When the sealing plug 35 moves towards the heat dissipation hole 22, the sealing disc 36 is bent towards the center of the sealing plug 35 under the extrusion of the heat dissipation hole 22, so as to be squeezed between the sealing plug 35 and the inner wall of the heat dissipation hole 22, which can greatly improve the sealing performance at the heat dissipation hole 22.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the present invention.
