Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a fully sealed intelligent protective grounding box. Background Technology

[0002] A grounding box is used to house and protect grounding wires. Similar to a grounding busbar, its main function is to collect grounding wires. Traditionally, grounding boxes require manual opening to secure external cables to the internal copper busbars. This process is cumbersome, and the internal sealing and safety of the grounding box are insufficient, resulting in limited functionality. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that traditional grounding boxes require manual opening of the box and then fixing of the external cable to the internal copper busbar, which is not only cumbersome to operate, but also lacks internal sealing and safety, and has relatively limited functionality.

[0004] The technical solution adopted by this invention to solve its technical problem is: a fully sealed intelligent protective grounding box, including a main box and a connecting cable. The main box is equipped with four metal conductor connectors, which are arranged side by side on the bottom surface of the main box. A metal connecting pipe is axially fixed to the upper end of each metal conductor connector, and the metal connecting pipe is connected to the metal conductor connector by a connecting copper busbar. A heat energy regulating device is fixedly installed on the outer walls of both sides of the main box. A spiral internal heat-conducting pipe is fixedly installed inside the main box around the metal conductor connector. An external heat-conducting chamber for connecting the heat energy regulating device and the spiral internal heat-conducting pipe is opened on the inner wall of the main box. The upper end of the connecting cable is inserted into the metal conductor connector and fixedly connected to the metal conductor connector through an intelligent connecting ring.

[0005] The three metal connecting pipes inside the main housing on the left side are fixedly fitted with cable sheath protectors.

[0006] The thermal energy regulating device includes a first liquid collection cover fixedly installed at the lower left end of the main body, a second liquid collection cover fixedly installed at the upper right end of the main body, and a bottom-mounted drive liquid pump installed inside the first liquid collection cover.

[0007] The inlet of the first liquid collecting cover and the outlet of the second liquid collecting cover are fixedly connected by an external heat dissipation copper pipe.

[0008] An annular limiting groove is provided on the outer arc-shaped surface of the intelligent connecting ring. An embedded temperature sensor controller is installed inside the annular limiting groove. The bottom end of the metal connecting tube is inserted into the intelligent connecting ring and connected to the connecting cable through an axially fixed metal connector.

[0009] The main housing is filled with a waterproof and insulating filling layer.

[0010] The main housing is equipped with a lateral hydraulic adjustment device for controlling the rotation of the connecting copper busbars.

[0011] The lateral hydraulic adjustment device includes an inner guide cylinder movably mounted on the inner wall of the main housing, a piston telescopic rod slidably mounted on the inner guide cylinder for controlling the connecting copper busbar, an inner return spring mounted inside the inner guide cylinder, and a three-way solenoid valve.

[0012] A lateral flow guide bracket for connecting the inner flow guide cylinder is fixedly installed on the inner wall of the main housing. The lateral flow guide bracket is fixedly connected to the external heat dissipation copper pipe through a three-way electrically controlled valve on the outer side of the main housing.

[0013] The bottom of the metal conductor connector is elastically fitted with a bottom support tube at the lower end of the main housing.

[0014] The beneficial effects of this invention are: (1) The fully sealed intelligent protective grounding box of the present invention has a connecting copper busbar and a cable sheath protector that are vertically attached and fixed inside the main box, which greatly improves the internal safety; (2) Waterproof insulating filler is poured inside the box, making the internal structure more stable and reliable and theft-proof, reducing the impact of environmental factors on the grounding box. (3) The intelligent connecting ring at the top of the connecting cable is inserted into the metal conductor connector and fixedly connected to the metal conductor connector, thereby inserting it into the box and sealing it. The convenience and sealing of the power cable installation process are improved by quick insertion and removal. (4) During use, the intelligent detection ring transmits data such as cable circulating current and conductor temperature to the cloud via 5G signal for real-time early warning, and protects the filling inside the grounding box; (5) A heat energy regulating device is fixedly installed on the outer walls of both sides of the main box. The internal heat is quickly dissipated to the outside through the spiral internal heat conduction pipe located outside the metal conductor connector inside the main box, which improves the internal heat dissipation effect without affecting the internal sealing. (6) The intelligent detection ring can also synchronously control the flow of internal coolant and quickly drive the copper busbar to separate from the metal connecting pipe in extreme cases, greatly improving safety.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 , Figure 3 and Figure 4 The fully sealed intelligent protective grounding box shown includes a main box 1 and a connecting cable 2. The main box 1 is equipped with four metal conductor connectors 3, which are arranged side by side on the bottom surface of the main box 1. A metal connecting pipe 4 is axially fixed to the upper end of the metal conductor connector 3. The metal connecting pipe 4 is connected to the metal conductor connector 3 by a connecting copper busbar 5. A heat energy regulating device is fixedly installed on the outer walls of both sides of the main box 1. A spiral internal heat conduction pipe 7 is fixedly installed inside the main box 1 around the metal conductor connectors 3. An external heat conduction chamber 8 is opened on the inner wall of the main box 1 to connect the heat energy regulating device and the spiral internal heat conduction pipe 7. The upper end of the connecting cable 2 is inserted into the metal conductor connector 3 through an intelligent connecting ring 9 and fixedly connected to the metal conductor connector 3.

[0023] To enhance internal safety, cable sheath protectors 10 are fixedly sleeved on the outside of the three metal connecting pipes 4 on the left side inside the main enclosure 1.

[0024] To coordinate with internal and external heat dissipation, the thermal energy regulation device includes a first liquid collection cover 61 fixedly installed at the lower left end of the main housing 1, a second liquid collection cover 62 fixedly installed at the upper right end of the main housing 1, and a bottom-mounted drive liquid pump 63 installed inside the first liquid collection cover 61.

[0025] The bottom-mounted drive liquid pump 63 is existing technology. It can freely change its speed by changing the internal temperature. Then, the heat dissipation oil located inside the first liquid collection shell 61 is introduced into the second liquid collection shell 62 through the spiral internal heat conduction pipe 7, and then flows back into the first liquid collection shell 61.

[0026] The first liquid collection cover 61 and the second liquid collection cover 62 are fixed to the outer walls of both sides of the main housing 1 by lateral bolts.

[0027] To facilitate external heat dissipation, the inlet of the first liquid collection cover 61 and the outlet of the second liquid collection cover 62 are fixedly connected by an external heat dissipation copper pipe 64.

[0028] To facilitate installation and monitoring of the working environment of the assembly surface, an annular limiting groove is provided on the outer arc surface of the intelligent connecting ring 9. An embedded temperature sensor controller 11 is installed inside the annular limiting groove. The bottom end of the metal connecting pipe 4 is inserted into the intelligent connecting ring 9 through an axially fixed metal connector and connected to the connecting cable 2.

[0029] The temperature sensor controller 11 is existing technology. During use, it transmits data such as cable circulation current and conductor temperature to the cloud via 5G signal through the intelligent detection ring for real-time early warning.

[0030] To improve the stability and sealing of the internal structure, the main housing 1 is filled with a waterproof and insulating filling layer 12.

[0031] The material of the waterproof insulating filler layer 12 is existing technology.

[0032] To complement the internal drive, the main housing 1 is equipped with a lateral hydraulic adjustment device for controlling the rotation of the connecting copper busbar 5.

[0033] To facilitate the flipping of the connecting copper busbar 5, a space is pre-formed on the outside of the connecting copper busbar 5 to facilitate its flipping.

[0034] To facilitate control of the inner guide cylinder 13, the lateral hydraulic adjustment device includes an inner guide cylinder 13 movably mounted on the inner wall of the main housing 1, a piston telescopic rod 14 slidably mounted on the inner guide cylinder 13 for controlling the connecting copper busbar 5, an inner return spring 15 installed inside the inner guide cylinder 13, and a three-way solenoid valve 16.

[0035] The three-way solenoid valve 16 is existing technology. It is linked with the temperature sensor controller 11. When the temperature is higher than the set maximum safe temperature, it will be activated, thereby controlling the drive fluid inside the external heat dissipation copper pipe 64 to flow into the lateral guide bracket 17.

[0036] In order to facilitate internal movement assembly and flow guidance, a lateral flow guide bracket 17 for connecting the inner flow guide cylinder 13 is fixedly installed on the inner wall of the main housing 1. The lateral flow guide bracket 17 is fixedly connected to the external heat dissipation copper pipe 64 through a three-way solenoid valve 16 on the outer side of the main housing 1.

[0037] The inner guide cylinder 13 is inserted into the side guide bracket 17 through the side guide tube and is in movable communication with the inside of the side guide bracket 17. The driving fluid inside the external heat dissipation copper pipe 64 can be introduced into the inner guide cylinder 13 through the side guide bracket 17, thereby driving the inner guide cylinder 13 to extend. Then, the reset spring inside the inner guide cylinder 13 is used to control the flipping and reset.

[0038] When the three-way solenoid valve 16 is adjusted, the driving fluid inside the external heat dissipation copper pipe 64 can be introduced into the inner guide cylinder 13 through the lateral guide bracket 17, thereby driving the inner guide cylinder 13 to extend. When the adjustment continues and the external heat dissipation copper pipes 64 on both sides of the three-way solenoid valve 16 are half-connected, the oil pressure introduced into the lateral guide bracket 17 will be reduced. At this time, the reset spring will control the inner guide cylinder 13 to retract and control the connecting copper busbar 5 to flip and reset.

[0039] To enhance bottom support, the bottom of the metal conductor connector 3 is elastically fitted with a bottom support tube 18 at the lower end of the main housing 1.

[0040] The bottom support tube 18, which extends downward elastically, can enhance the support of the bottom of the main housing 1 and provide closed protection around the connecting cable 2.

[0041] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
