DETAILED DESCRIPTION

[0024] 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.

[0025] When implementing: Figure 1-7As shown, the buried liquid-cooled charging pile comprises: land 1, a first shell 2, a capping mechanism 3, a charging pile body 4, a liquid cooling mechanism 6 and a clamping mechanism 7. The first shell 2 is embedded inside the land 1, and the upper end of the first shell 2 is rotatably connected to the capping mechanism 3. The charging pile body 4 is arranged inside the first shell 2, and the side of the charging pile body 4 is provided with a winding mechanism 5. The side of the charging pile body 4 is symmetrically provided with two grooves 8. The liquid cooling mechanism 6 is arranged inside the first shell 2, and the clamping mechanism 7 is arranged on both sides of the first shell 2. When the device is in use, the first shell 2 is installed on the inside of the land 1 during use, and then the charging pile body 4 is installed on the inside of the first shell 2, clamped by the clamping mechanism 7, and then blocked by the capping mechanism 3. During use, the winding mechanism 5 is pulled to charge. During the charging process, the charging pile body 4 heats up and triggers the liquid cooling mechanism 6 to cool down the charging pile body 4.

[0026] The covering mechanism 3 includes a rotating block 31, a cover plate 32, a first connecting block 37 and a bolt 38. The rotating block 31 is arranged on the side of the first shell 2, and the rotating block 31 is rotatably connected to the cover plate 32. The cover plate 32 and the side of the first shell 2 are both connected with the first connecting block 37. The two first connecting blocks 37 are connected by bolts 38. When the device is in use, the first shell 2 is blocked by the cover plate 32 and rotation. After blocking, the first connecting block 37 is locked by the bolts 38, so that the cover plate 32 closes the first shell 2.

[0027] A first slot 33 is provided at the upper end of the cover plate 32, a handle 34 is provided inside the first slot 33, a second slot 35 is provided at the upper end of the first slot 33, a round hole is provided inside the second slot 35, a soft rubber pad 39 is provided inside the second slot 35, and two water outlet holes 36 are symmetrically provided inside the second slot 35. When the device is in use, when the device needs to be opened for maintenance, the bolt 38 can be rotated, and then the handle 34 is pulled to drive the cover plate 32 to rotate and open through the rotating block 31. On rainy days, water is discharged through the water outlet holes 36. At the same time, the soft rubber pad 39 is slidably connected to the power cord 55, and the friction force is large to prevent water from flowing into the inner side of the first shell 2.

[0028] The winding mechanism 5 includes a second connecting block 51, a rotating rod 52, a torsion spring 53, a second shell 54, a power cord 55 and a power connector 56. Two second connecting blocks 51 are symmetrically arranged on the side of the charging pile body 4. A rotating rod 52 is rotatably connected between the two second connecting blocks 51. A torsion spring 53 is arranged on the side of the rotating rod 52. The side of the rotating rod 52 is connected to the second shell 54. The side of the second shell 54 is wrapped with a power cord 55. One end of the power cord 55 is connected to the charging pile body 4, and the other end of the power cord 55 is connected to the power connector 56.

[0029] The power connector 56 penetrates the soft rubber pad 39, and the soft rubber pad 39 is snap-connected to the inner side of the second slot 35. When the device is in use and needs to be charged, the power connector 56 is pulled to pull out the power cord 55, and at the same time, the power cord 55 drives the rotating rod 52 to rotate. Since the friction between the power cord 55 and the soft rubber pad 39 is relatively large, it is not easy for the power cord 55 to be pulled back to the side of the second shell 54 by the torsion spring 53 when it is pulled out. After charging is completed, the operator can assist in pushing the power cord 55 to reel in the side of the second shell 54, and drive the rotating rod 52 to rotate through the torsion spring 53 to assist in reeling.

[0030] The liquid cooling mechanism 6 includes a liquid cooling box 61 and a cooling plate 62 . Two liquid cooling boxes 61 are symmetrically arranged on the inner side of the first shell 2 , and cooling plates 62 are arranged on the sides of the liquid cooling boxes 61 .

[0031] A third shell 63 is provided at the lower end of the cover plate 32, and the third shell 63 is slidably connected with a first slider 64. A temperature sensor 66 is embedded at the lower end of the first slider 64. A first spring column 65 is provided on the inner side of the third shell 63, and the first spring column 65 is connected to the first slider 64. When the device is in use, when the cover plate 32 completely blocks the first shell 2, the first slider 64 is fitted with the charging pile body 4, and the first slider 64 is pushed by the first spring column 65, so that the temperature sensor 66 is tightly fitted with the charging pile body 4. When the temperature of the charging pile body 4 is high during charging, the liquid cooling box 61 is triggered by the temperature sensor 66 to cool down the charging pile body 4, and the charging pile body 4 is cooled by the cold conduction plate 62 fitting with the charging pile body 4.

[0032] The clamping mechanism 7 includes a fourth shell 71, a second slider 72, a clamping roller 73 and a second spring column 74. The fourth shell 71 is connected to both sides of the inner side of the first shell 2. The fourth shell 71 is slidably connected to the second slider 72. The second slider 72 is rotatably connected to the clamping roller 73 at the side. A second spring column 74 is arranged on the inner side of the first shell 2. The second spring column 74 is connected to the second slider 72. When the device is in use, when installing the charging pile body 4, the charging pile body 4 is inserted between the two clamping rollers 73, and the clamping roller 73 is squeezed, so that the second slider 72 slides on the inner side of the fourth shell 71 to squeeze the second spring column 74. When the clamping roller 73 reaches the side of the groove 8, the installation is completed.

[0033] When the utility model is in use, the first shell 2 is installed on the inner side of the land 1, and then the charging pile body 4 is installed on the inner side of the first shell 2. When installing the charging pile body 4, the charging pile body 4 is inserted between the two clamping rollers 73, and the clamping rollers 73 are squeezed, so that the second slider 72 slides on the inner side of the fourth shell 71 to squeeze the second spring column 74. When the clamping roller 73 reaches the side of the groove 8, the installation is completed at this time;

[0034] At this time, the first housing 2 is blocked by the cover plate 32 and rotated, and after blocking, the first connecting block 37 is locked by the bolt 38, so that the cover plate 32 closes the first housing 2;

[0035] On rainy days, water is discharged through the water outlet 36, and the soft rubber pad 39 is slidably connected with the power cord 55, and the friction force is large, which prevents water from flowing into the inside of the first shell 2;

[0036] When charging is needed, the power connector 56 is pulled to pull out the power cord 55, and at the same time, the power cord 55 drives the rotating rod 52 to rotate. Since the friction between the power cord 55 and the soft rubber pad 39 is relatively large, the power cord 55 is not easily pulled back to the side of the second shell 54 by the torsion spring 53 when it is pulled out. After charging is completed, the operator can assist in pushing the power cord 55 to reel in the side of the second shell 54, and drive the rotating rod 52 to rotate through the torsion spring 53 to assist in reeling.

[0037] When the cover plate 32 completely blocks the first shell 2, the first slider 64 fits with the charging pile body 4, and the first spring column 65 pushes the first slider 64, so that the temperature sensor 66 fits tightly with the charging pile body 4. When the temperature of the charging pile body 4 is high during charging, the temperature sensor 66 triggers the liquid cooling box 61 to cool the charging pile body 4, and the cooling plate 62 fits with the charging pile body 4 to cool the charging pile body 4.

[0038] When the device needs to be opened for maintenance, the bolt 38 can be rotated, and then the handle 34 can be pulled to drive the cover plate 32 to rotate and open through the rotating block 31, and the device can be pulled out by pulling the charging pile body 4, which is convenient for maintenance and improves the overall practicality of the device.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
