[0024] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0025] Please see Figures 1-5 As shown, a docking charging device for underground mobile equipment includes a mobile power supply 1. A power cord 101 is fixedly provided at the middle of the rear end of the outer surface of the mobile power supply 1. A storage cavity 102 is opened at the middle of the front end of the outer surface of the mobile power supply 1. A cavity door 103 is movably installed on one side of the front end of the storage cavity 102 via a hinge. A ring-shaped limiting guide rail 2 is fixedly installed at the rear end of the storage cavity 102.

[0026] It should be noted that the mobile power bank 1 is used as a power replenishment point. It is connected to an external power supply device through the power cord 101. The power is delivered to the mobile power bank 1 and then converted by the mobile power bank 1 to replenish the underground equipment. The charging cable 3 of the mobile power bank 1 can be sealed and stored with the help of the storage cavity 102 and the cavity door 103, so as to reduce the impact of the harsh underground environment on the charging cable 3.

[0027] The inner surface of the limiting guide rail 2 is movably fitted with a limiting rotating ring 201. The upper and lower front ends of the outer surface of the limiting guide rail 2 are movably fitted with a aligning frame 202. A limiting groove is opened through the middle of the front end of the outer surface of the limiting guide rail 2. The rear end of the aligning frame 202 is protruding and is fixedly connected to the limiting rotating ring 201 through the limiting groove.

[0028] It should be noted that by moving the straightening frame 202, the limiting ring 201 can be controlled to rotate clockwise and counterclockwise along the limiting guide rail 2. The rotation of the limiting ring 201 drives the straightening frame 202 to rotate synchronously. When the straightening frame 202 rotates clockwise, the charging cable 3 wrapped on its surface can be extended and released. When the straightening frame 202 rotates counterclockwise, the extended charging cable 3 can be wound and stored, ensuring the straightness of the extended charging cable 3. Since the limiting ring 201 and the straightening frame 202 are made of rubber, they have high elasticity and adhesion. When the limiting ring 201 contacts the limiting guide rail 2, its surface will deform and generate a large friction force with the inner surface of the limiting guide rail 2 to form a tight contact, thereby ensuring the stability of the connection between the limiting ring 201 and the limiting guide rail 2 without external force.

[0029] A charging cable 3 is movably mounted on the outer surface of the organizing frame 202. One end of the charging cable 3 is connected to the power bank 1, and the other end of the charging cable 3 is fixedly equipped with a charging head 301. A fixing sleeve 4 is fixedly mounted on the outer surface of the charging head 301. A support ring 401 is fixedly mounted on the outer ring surface of the fixing sleeve 4. A fixing ring 5 is movably mounted below the support ring 401. A connecting rod 402 is movably inserted through the center of each of the four sides of the upper surface of the support ring 401. The other end of the connecting rod 402 is fixedly connected to the upper surface of the fixing ring 5. A magnetic ring 501 is fixedly mounted on the lower surface of the fixing ring 5. An isolation sleeve 502 is movably mounted on the outer surface of the magnetic ring 501.

[0030] It should be noted that the charging cable 3 is extended to control the charging head 301 to be inserted and connected to the charging port of the device. After the connection is completed, the isolation sleeve 502 on the outer surface of the magnetic ring 501 can be removed. Since the surface of the device is mostly made of steel, the magnetic ring 501 can be attracted to the outer surface of the charging port. The magnetic ring 501 drives the fixing ring 5 to control the support ring 401 to stably support the charging head 301, so as to ensure the stability of the connection between the charging head 301 and the device charging port. At the same time, the isolation sleeve 502 and the fixing ring 5 are both made of rubber, and their insulation properties can effectively isolate the magnetic field of the magnetic ring 501, reducing the influence of the magnetic field of the magnetic ring 501 when the magnetic ring 501 is not in use.

[0031] When using this utility model, firstly, both the downhole equipment and the mobile power supply 1 can be moved to a stable position downhole. At this time, the cavity door 103 can be opened and the straightening frame 202 can be rotated clockwise to extend and release the charging cable 3 wrapped on its surface. Then, the extended charging cable 3 can be stretched to control the charging head 301 to dock with the charging port of the downhole equipment to complete the power replenishment. After the charging head 301 is docked and inserted, the isolation sleeve 502 can be removed from the magnetic ring 501 and the magnetic ring 501 can be adsorbed on the outside of the charging port of the downhole equipment. Utilizing the magnetic adsorption between the magnetic ring 501 and the downhole equipment, the support ring 401 is controlled by the fixing ring 5 to provide stable support for the charging head 301, thereby improving the stability of the connection between the charging head 301 and the downhole equipment.

[0032] After the power supply is replenished, the charging head 301 is taken out and the magnetic ring 501 is covered again with the isolation sleeve 502. At this time, the organizing frame 202 can be rotated counterclockwise to wind and store the charging cable 3 into the storage cavity 102, thereby completing the sorting and sealing of the large-span charging cable 3 and reducing the impact of the harsh underground environment on the charging cable 3.

[0033] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
