[0002] In the existing high- and low-voltage power transmission equipment, the switchgear and transformers will occupy a large space. In order to save space, box-type substations will be set up. A box-type substation is a special equipment used in the power supply and distribution system, which is divided into different forms such as buried type and semi-buried type.

[0003] In the existing technology, the box-type substation organically combines functions such as transformer step-down and low-voltage power distribution, and is installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulated, fully enclosed steel structure box. Under normal circumstances, the whole machine is buried underground, and the ground can be greened, beautified or used as a road or a parking lot;

[0004] In the existing technical solutions, parking lots are all in the form of conventional parking lots. However, due to the increase in new energy vehicles, it is necessary to set up charging piles. If charging piles are set up separately, some communities and public places cannot be compatible at the same time due to limited area, resulting in waste of space. At the same time, long-distance power transmission will cause voltage drop and waste of electric energy. Summary of the Invention

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a technical solution:

[0029] See also Figures 1 to 5, A buried box-type substation for charging automobiles, including a pre-buried box 1. One side of the outer wall of the pre-buried box 1 is fixedly provided with a pre-buried shell 2, and an opening and closing mechanism 3 is arranged inside the pre-buried shell 2; The opening and closing mechanism 3 includes a housing 301, the housing 301 is fixed at the inner bottom end of the pre-buried shell 2, a double-output motor 302 is embedded in the housing 301, one end of the double-output motor 302 is connected with a first worm 303, the outer wall of the end of the first worm 303 penetrating into the pre-buried box 1 is connected with a first worm gear 304, a first threaded rod 305 penetrates out of the inside of the first worm gear 304, a slider 306 is slidably connected above the outer wall of the first threaded rod 305, one end of the slider 306 is fixed with a baffle 307, an installation groove 308 is opened at the position of the outer wall of the pre-buried box 1 corresponding to the baffle 307, the baffle 307 forms a sliding structure with the pre-buried box 1 through the slider 306, the slider 306 is threadedly connected with the first threaded rod 305, a limiting groove 4 is opened at the position of the outer wall of the pre-buried box 1 corresponding to the slider 306, and a limiting rod 5 penetrates out of the inside of the other slider 306.

[0030] By adopting the above technical solution, both the pre-buried box 1 and the pre-buried shell 2 are buried underground. When the automobile parks in the parking space, after the double-output motor 302 works, through the transmission of the first worm 303 and the first worm gear 304, the first threaded rod 305 rotates accordingly, so that the slider 306 drives the baffle 307 along the limiting groove 4, and stably slides under the guidance of the first threaded rod 305 and the limiting rod 5, thereby opening the installation groove 308, enabling the driver to operate the charging pile embedded in the installation groove 308. After the vehicle drives away after charging, the baffle 307 is reset under the drive of the double-output motor 302, avoiding corrosion or pollution caused by rainwater, etc. By integrating the pre-buried box 1 and the charging pile, space is saved and waste or voltage instability caused during the cable pulling process is avoided.

[0031] Specifically, as Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, a pressing block 6 penetrates out of one side of the top end of the pre-buried shell 2. Below the end of the pressing block 6 penetrating into the pre-buried shell 2 is connected with a resisting rod 8. A spring 7 is sleeved outside the resisting rod 8. A limiting hole 9 is opened at the position of the top end of the housing 301 corresponding to the resisting rod 8. A penetrating groove 10 is opened on one side of the pressing block 6 at the top end of the pre-buried shell 2. A limiting mechanism 11 is arranged inside the penetrating groove 10. The limiting mechanism 11 includes a blocking block 1101, the blocking block 1101 is slidably connected inside the penetrating groove 10, a sleeve 1102 is fixed below the blocking block 1101, a second threaded rod 1103 penetrates out of the bottom end of the sleeve 1102, the limiting mechanism 11 further includes a second worm 1105, the second worm 1105 is connected to the other end of the double-output motor 302, and a second worm gear 1104 is connected to the outer wall of the second worm 1105.

[0032] By adopting the above technical solution, when the vehicle enters the parking space, the rear wheel presses and tightens the pressing block 6, so that the spring 7 elastically contracts to allow the resistance rod 8 to penetrate the limiting hole 9 provided in the casing 301 to trigger the start button of the dual-output end motor 302. When the vehicle leaves, the resistance rod 8 is disengaged and closed by the spring 7 reset, so that the baffle 307 can be automatically controlled to avoid the driver's operation. When the dual-output end motor 302 is working, it drives the second worm 1105 at the same time, and drives the second threaded rod 1103 to rotate through the second worm gear 1104. The sleeve 1102 set on the second threaded rod 1103 is fixed at the bottom end of the blocking block 1101. Under the limit of the groove 10, the sleeve 1102 pushes the blocking block 1101 upward to slide, thereby limiting and locking the rear wheels of the vehicle. When charging is not completed, the dual-output end motor 302 is in a stopped state, thereby effectively controlling the vehicle to leave when charging is not completed.

[0033] Working principle: the embedded box 1 is half buried underground and the top of the embedded shell 2 is flush with the road surface. The dual-output motor 302 drives the first worm 303, thereby driving the first worm wheel 304 to drive the first threaded rod 305 to rotate, allowing the slider 306 to slide stably along the first threaded rod 305 and the limit rod 5, along the limit groove 4, thereby driving the baffle 307 to move and open the placement groove 308, making it convenient for the driver to operate the charging pile embedded in the placement groove 308. When the car stops, the rear wheel pressure By pressing the block 6 tightly, the spring 7 elastically contracts to allow the resistance rod 8 to penetrate into the limiting hole 9 provided in the casing 301 and touch the dual-output motor 302, so that the baffle 307 can be automatically opened after the vehicle is stopped. At the same time, another set of second worm gears 1105 rotates accordingly, and the second threaded rod 1103 is driven to rotate via the second worm gear 1104. At the same time, under the limitation of the groove 10, the blocking block 1101 rises along the second threaded rod 1103 through the sleeve 1102, thereby locking the vehicle tire.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
