When the existing mining power connector is used, the cable conductor is inserted into the corresponding terminal of the connector, and then the two connectors are docked to connect the circuit. However, since the connectors are usually docked by staff, the power may not be turned off in advance during docking, which may easily cause electric shock to the staff, which is quite dangerous. In addition, the environment in the mine is special, with dust, high humidity, and a wide range of temperature changes. When dust or water mist enters the connector docking, it is easy to affect the docking of the connector, thereby affecting the normal operation of the circuit.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0033] by Figure 1 Determine the direction based on the viewing direction, and determine the front, back, left, and right directions.

[0034] A waterproof and dustproof mining power connector, such as Figure 1-Figure 9 As shown, it includes a first connector 1, a second connector 2 and a docking mechanism 3. The left part of the docking mechanism 3 is slidably connected to the first connector 1, and the right part of the docking mechanism 3 is slidably connected to the second connector 2. The first connector 1 and the second connector 2 are both provided with fastening bolts to facilitate fixing the cables. The docking mechanism 3 is used to dock the first connector 1 and the second connector 2.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the docking mechanism 3 includes a connecting frame 30, a connecting shell 31, a bidirectional motor 32 and a screw rod 33. The first connector 1 and the second connector 2 are both slidably connected to the connecting frame 30. A heat dissipation groove is opened on the upper part of the connecting frame 30 to facilitate heat dissipation. The middle part of the connecting frame 30 is connected to the connecting shell 31, and the front part of the connecting frame 30 is connected to the bidirectional motor 32. The output shaft of the bidirectional motor 32 is connected to the screw rod 33, and the screw rod 33 is rotatably connected to the connecting frame 30. The first connector 1 is threadedly connected to the screw rod 33 on the left, and the second connector 2 is threadedly connected to the screw rod 33 on the right.

[0036] When using the present invention, firstly, the cables are connected to the first connector 1 and the second connector 2 respectively. After the connection is completed, the bidirectional motor 32 is started to drive the screw rod 33 to rotate, so that the first connector 1 and the second connector 2 move close to each other and dock in the connection shell 31, thereby automatically docking the connectors to avoid electric shock accidents caused by manual docking, and the docking point of the connectors can be waterproof and dustproof, thereby improving the safety of mining power connection.

[0037] like Figure 1 and Figure 5 As shown, it also includes a moving mechanism 4, which includes a connecting plate 40, a moving vehicle 41 and fixing screws 42. The lower side of the connecting frame 30 is detachably connected to the connecting plate 40 through four fixing screws 42, and the lower side of the connecting plate 40 is connected to the moving vehicle 41. The lower part of the moving vehicle 41 is rotatably provided with four moving wheels for easy movement.

[0038] When the mining equipment and power supply need to be moved, the connecting frame 30 can be installed on the connecting plate 40 by fixing screws 42, and then the mobile vehicle 41 drives the connecting frame 30 to move, so that it can move with the mining equipment and power supply, reducing the number of plug-in and unplugging times of the first connector 1 and the second connector 2.

[0039] like Figure 1 and Figure 6As shown, a prompt mechanism 5 is also included, which includes a guide column 50, a first spring 51, a rotating roller 52, a rotating plate 53, a guide knocking column 54, a second spring 55 and a prompt bell 56. Three guide columns 50 are slidably connected to the left and right sides of the connecting frame 30. The first spring 51 is connected between the guide columns 50 and the connecting frame 30. The upper side of the guide column 50 is rotatably connected to the rotating roller 52. The front side of the rotating roller 52 is connected to the rotating plate 53.

The front side of the guide column 50 is connected to a prompt bell 56.

[0040] By using the prompt mechanism 5 of the present device, the staff can be prompted about the docking status of the first connector 1 and the second connector 2. After the cable is connected to the first connector 1 and the second connector 2, the cable is located on the upper side of the rotating roller 52. Through the action of the first spring 51, the rotating roller 52 supports the cable, thereby preventing the cable from being worn when it moves. When the first connector 1 and the second connector 2 move and drive the cable to move for docking or detachment, the cable drives the rotating roller 52 to rotate, and the rotating plate 53 rotates, so that the guide knocking column 54 knocks the prompt bell 56 under the action of the second spring 55, causing the prompt bell 56 to emit a prompt sound, thereby prompting the staff about the docking status of the first connector 1 and the second connector 2.

[0041] like Figure 1 and Figure 7 As shown, a protection mechanism 6 is also included, which includes a conductive rod 60, a connecting block 61 and a grounding wire 62.

The front side of the conductive rod 60 is connected to the connecting block 61, and the connecting block 61 is connected to the grounding wire 62, which is in contact with the ground.

[0042] The protection mechanism 6 of the device can improve circuit safety. When leakage occurs at the joint between the first connector 1 and the second connector 2, the current is introduced into the conductive rod 60, and then the current is introduced into the ground through the grounding wire 62, thereby improving circuit safety and reducing the risk of electric shock.

[0043] like Figure 1 and Figure 8 As shown, a cooling mechanism 7 is also included. The cooling mechanism 7 includes a shell 70 and a fan 71. Four shells 70 are connected to the lower part of the connecting frame 30, and the shells 70 are rotatably connected to the fans 71.

[0044] By using the cooling mechanism 7 of the device, the first connector 1 and the second connector 2 can be cooled, and the fan 71 on the outer shell 70 can be started to accelerate the circulation of surrounding air, thereby cooling the first connector 1 and the second connector 2 and preventing high temperature from affecting the normal operation of the first connector 1 and the second connector 2.

[0045] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a splicing mechanism 8, which includes a first splicing block 80 and a second splicing block 81. The front sides of the left and right parts of the connecting frame 30 are connected to the first splicing block 80, and the rear sides of the left and right parts of the connecting frame 30 are connected to the second splicing block 81.

[0046] By using the splicing mechanism 8 of the present device, the connecting frame 30 can be spliced. When multiple cables need to be connected, the first splicing block 80 is engaged with the second splicing block 81 on another connecting frame 30 to vertically splice the connecting frame 30, thereby achieving the effect of splicing the connecting frame 30 and improving the overall stability of the connecting frame 30.
