[0028] Beneficial Effects

[0029] The present invention provides a safe self-locking box-type substation. Compared with the prior art, it has the following beneficial effects:

[0030] (1) The safety self-locking box-type substation pushes the connecting seat and the tooth plate and the limit block 2 to slide downward in the limit groove 2 through the electric push rod. The tooth plate drives the rack downward to drive the transmission gear and the travel screw to rotate. The sliding block moves along the travel screw. The sliding block drives the limit block 3 to slide in the inner wall of the limit groove 3. The sliding block drives the L-shaped limit seat through the opening to enter the inner wall of the trapezoidal groove. After the L-shaped limit seat enters the trapezoidal groove, it presses down the moving block to drive the limit block 1 to slide downward in the inner wall of the limit groove 1. The moving block slides downward in the inner wall of the accommodating groove. And stretch the spring. When the L-shaped limit seat moves to the left side of the inner wall of the trapezoidal groove, the moving block pushes the locking seat through the groove into the inner wall of the locking mouth to engage the limit. After the door is closed, the staff can start the preset program through the face recognition controller, and the self-locking component can be used to quickly complete the automatic locking of the door. There is no need to manually operate various components. It is easier to lock the door, and the influence of external factors on the locking of the door is reduced to a greater extent, and the operation is more convenient.

[0031] (2) The safe self-locking box-type substation starts working by starting a preset program through a face recognition controller. When the temperature sensor senses that the temperature inside the box is in a normal state, the movable end of the electric telescopic rod contracts and drives the movable seat to slide upward in the inner wall of the installation cavity. The sealing block gradually separates from the heat dissipation port. The movable seat drives the limit slider to slide upward in the inner wall of the corresponding limit slide groove. The sealing block increases the space for leakage of the heat dissipation port, and heat can be quickly discharged from the heat dissipation port. The dustproof plate mainly has the function of preventing dust. When the temperature sensor senses that the temperature inside the box is gradually rising, the sealing block gradually separates from the heat dissipation port, so that the space of the heat dissipation port is fully opened. When the temperature inside the box is normal, the normal heat dissipation work can be maintained by the mutual cooperation of the various components of the opening and closing components. When the temperature rises, the heat dissipation port is quickly fully opened, and the heat dissipation effect is improved by the mutual cooperation of the heat dissipation components.

[0032] (3) The safe self-locking box-type substation starts working by starting the preset program through the face recognition controller. The driving motor drives the pulley, the rotating shaft and the cooling fan to rotate. When the pulley on the right side rotates, it drives the belt and the pulley on the left side to rotate. Then, when the rotating shafts on both sides rotate, the cooling fan is driven to rotate at high speed, and the heat inside the box body begins to dissipate heat. The heat can be discharged through the installation port, so that the heat inside the box body can be quickly discharged from the bottom and top, preventing the temperature inside the box from being too high and avoiding affecting the normal operation of its internal equipment.

[0056] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0057] When working, first connect the electric telescopic rod 24, the electronic lock, the electric push rod 32, the temperature sensor 42, and the drive motor 47 through the face recognition controller 6. When the box door 5 needs to be closed, the box door 5 is closed and contacted with the box body 1 by pushing the handle 7. The staff performs face recognition through the face recognition controller 6, and then operates the face recognition controller 6 to start the set self-locking program. The electric push rod 32 pushes the connecting seat 324 and the tooth plate 33 to move downward. When the tooth plate 33 moves downward, it drives the limit block 2 35 to slide downward in the inner wall of the limit groove 2 322. The tooth plate 33 drives the rack 34 to move downward and then drives the transmission gear 37 meshing with the rack 34 to rotate. When the transmission gear 37 rotates, it drives the travel screw 36 to rotate, so that the travel When the screw rod 36 rotates, it drives the sliding block 38 to move linearly from right to left along the outer wall of the advancing screw rod 36, so that the sliding block 38 drives the limiting block 39 to slide in the inner wall of the limiting groove 321 to prevent the sliding block 38 from flipping over when moving, and the sliding block 38 drives the L-shaped limiting seat 310 to enter the inner wall of the trapezoidal groove 314 through the opening 319. After the L-shaped limiting seat 310 enters the trapezoidal groove 314, it starts to press down the moving block 311 to drive the limiting block 1 313 to slide downward in the inner wall of the limiting groove 1 317. At the same time, the moving block 311 slides downward in the inner wall of the accommodating groove 316 and stretches the spring 312. When the L-shaped limiting seat 310 moves to the left side of the inner wall of the trapezoidal groove 314, the moving block 311 pushes the locking seat 31 5 enters the inner wall of the locking opening 323 through the groove 318 to engage the limit, thereby completing the installation and fixation of the box door 5. When the self-locking component 3 needs to be inspected, the staff can open the electronic lock after recognizing the face through the face recognition controller 6, which can drive the closed door 31 to open and inspect the components inside the self-locking component 3. When the substation equipment installed inside the box body 1 is working, a lot of heat will be generated. The preset program is started by the face recognition controller 6 to start working. When the temperature sensor 42 senses that the temperature inside the box body 1 is in a normal state, the movable end of the electric telescopic rod 24 is contracted to drive the moving seat 25 to slide upward in the inner wall of the installation cavity 22, thereby driving the sealing block 27 to gradually separate from the heat dissipation port 28. When the moving seat 25 is moved upward, the sealing block 27 is gradually separated from the heat dissipation port 28. When the movable seat 25 is active, it drives the limit slider 26 to slide upward in the inner wall of the corresponding limit slot 23, so that the sealing block 27 increases the space for the heat dissipation port 28 to be leaked, so that the heat can be quickly discharged from the heat dissipation port 28. The dustproof plate 29 mainly has the function of dustproofing, and can also prevent small external animals from entering the interior of the box body 1. When the temperature sensor 42 senses that the temperature inside the box body 1 is gradually rising, the sealing block 27 gradually separates from the heat dissipation port 28, so that the space of the heat dissipation port 28 is completely opened, and then the face recognition controller 6 starts the preset program to start working, and drives the pulley 49, the shaft and the cooling fan 46 to rotate through the driving motor 47. When the pulley 49 on the right side rotates, it drives the belt 410 and the pulley 49 on the left side to rotate.Then, when the rotating shafts on both sides rotate, the cooling fan 46 is driven to rotate at high speed, and the heat inside the box body 1 begins to be dissipated. The heat can be discharged through the installation port 41, so that the heat inside the box body 1 can be quickly discharged from the bottom and the top, so that when the box door 5 is closed, the self-locking program can be activated by the face recognition controller 6 to lock the box door 5. At the same time, when the substation equipment inside the box body 1 is working, different cooling methods are activated according to different temperatures. The overall work is highly automated and does not require too much manual participation.
