[0031] In order to solve the problem that the existing car charging piles are fixed on the ground, when there is a lot of water on the ground due to heavy rain, the charging piles are immersed in the water and easily cause water to penetrate into the interior and be damaged, please refer to Figure 1-Figure 6 , provide the following preferred technical solutions:

[0032] Positioning holes 101 are respectively provided at the four corners inside the device housing 1, and the end of the positioning hole 101 extends to the bottom of the device housing 1. A positioning column 102 is movably inserted into the positioning hole 101, and the lower end of the positioning column 102 passes through the end of the positioning hole 101, and the bottom of the positioning column 102 is fixedly connected to the top of the device base 5, and the top of the device base 5 supports the device housing 1. Buffer pads are evenly arranged on the top of the device base 5 outside the positioning column 102. Positioning grooves 103 are respectively provided on the side walls around the device housing 1 near the bottom. The positioning grooves 103 are located below the mounting inclined groove 13 and maintain a large distance therefrom. A lightweight floating plate 6 is movably provided between the inner walls on both sides of the top of the positioning groove 103. Positioning shafts 62 are fixedly connected to the outer walls on both sides of the lightweight floating plate 6 near the top. The inner walls at both ends of the positioning groove 103 are provided with corresponding positioning shafts 62. A first convex hole, the end of the positioning shaft 62 extends to the inside of the first convex hole, a spring 63 is wound on the outer wall of the positioning shaft 62 in the first convex hole, and the outer end of the spring 63 is fixedly connected to the inner wall of the first convex hole. The edges of the two ends of the outer wall of the lightweight floating plate 6 close to the positioning groove 103 are respectively movably connected with telescopic connecting rods 61, and the end of the telescopic connecting rod 61 is movably connected to the inner wall of the positioning groove 103. An inner groove 105 is provided at the middle of the bottom end of the device housing 1, and a liquid level sensor 106 is fixedly connected to the lower end of the top plate of the inner groove 105. A displacement sensor is also provided at the lower end of the top plate of the inner groove 105. Installation cavities 104 are respectively opened at the bottom of the device housing 1 at the four corners of the outer side of the inner groove 105. The installation cavities 104 are respectively arranged corresponding to the positioning holes 101 and are connected thereto, and an adjusting member 7 is movably provided on the inner wall of the installation cavity 104;

[0033] The adjusting member 7 comprises a positioning gear 71 and an axle rod fixedly connected to the outer walls on both sides of the positioning gear 71. The positioning gear 71 is movably arranged on the inner wall of the installation cavity 104 through the axle rod on one outer wall. A winding wheel 72 is fixedly connected to the outer wall of the axle rod on the other side of the positioning gear 71. A mounting strip 73 is movably sleeved on the outer wall of the axle rod of the positioning gear 71 outside the winding wheel 72, and an adjusting rope 74 is wound on the outer wall of the winding wheel 72. The other end of the adjusting rope 74 passes through the inner wall at the top of the positioning groove 103 and is fixedly connected to the outer wall of the lightweight floating plate 6. An auxiliary gear 75 is movably arranged on the side wall at the end of the installation strip 73. One end of the auxiliary gear 75 extends into the interior of the positioning hole 101. An electric push rod 76 is movably connected to the outer wall at the bottom of the installation strip 73. The liquid level sensor 106 and the electric push rod 76 are both electrically connected to the control host inside the equipment housing 1. The end of the electric push rod 76 is fixedly connected to the inner wall of the installation cavity 104.

[0034] A limiting groove 1021 is provided on the outer wall of the positioning column 102 close to the installation cavity 104, and a rack 1022 is fixedly connected to the inner wall of the limiting groove 1021 corresponding to the installation cavity 104. The rack 1022 is only arranged on the inner wall of the lower half of the limiting groove 1021. The setting length of the rack 1022 is just enough to realize the winding of the adjustment rope 74 while ensuring that the lightweight floating plate 6 is vertically folded in the positioning groove 103. The limiting groove 1021 is arranged corresponding to the auxiliary gear 75.

[0035] When the lightweight floating plate 6 is vertically engaged at the end of the positioning groove 103, the clockwork spring 63 is in a compressed state. At this time, the adjustment rope 74 is completely tightened and wound on the outer wall of the winding wheel 72, and the two ends of the auxiliary gear 75 are respectively engaged with the positioning gear 71 and the rack 1022, and the electric push rod 76 is at the maximum extension length.

[0036] Specifically, when water accumulates on the road surface and the depth of the accumulated water submerges the device base 5 and contacts the device housing 1, the accumulated water enters the inner groove 105 at the bottom of the device housing 1 from the gap between the device base 5 and the device housing 1. After the accumulated water fills the inner groove 105, it contacts the liquid level sensor 106 to trigger an alarm signal, indicating that the depth of the accumulated water outside the charging pile has reached the warning line. The control host inside the device housing 1 controls the electric push rod 76 to retract. When the electric push rod 76 retracts, it uses the mounting strip 73 to drive the auxiliary gear 75 to rotate counterclockwise based on the shaft of the positioning gear 71. The auxiliary gear 75 rolls in contact with the positioning gear 71 and separates from the rack 1022 on the positioning column 102, thereby releasing the restriction of the auxiliary gear 75 on the positioning column 102 and the positioning gear 71, so that the winding wheel 72 and the positioning gear 71 can rotate. Under the winding and releasing action of the clockwork spring 63, the lightweight floating plate 6 in the positioning groove 103 on the side walls of the device housing 1 deflects based on the positioning shafts 62 at both ends. When the lower end of the floating plate 6 deflects and moves upward, the telescopic connecting rods 61 on both sides are stretched. At the same time, the lightweight floating plate 6 uses the adjusting rope 74 to pull the winding wheel 72 based on the positioning gear 71 to release the rotation of the adjusting rope 74. The lower end of the lightweight floating plate 6 deflects and moves upward until it is level with the top of the positioning groove 103 port. After the accumulated water continues to surge and immerse the charging pile to contact the lightweight floating plate 6, the lightweight floating plate 6 uses the buoyancy in the accumulated water to drive the device housing 1 to slide upward based on the positioning column 102 on the top of the device base 5, ensuring the stability of the device housing 1 in the water. At the same time, it avoids the problem of accumulated water penetrating into the interior of the device and causing damage to the equipment after the accumulated water surges and immerses the charging pile, realizing automatic protection of the charging pile when it is immersed in water. When the accumulated water recedes, the charging pile slowly slides down along the positioning column 102 based on the suspension of the lightweight floating plate 6. After the displacement sensor under the top plate of the inner groove 105 detects that the height of the device housing 1 has dropped, it controls the electric push rod 76 to extend and push the auxiliary gear 75 to reset. The device housing 1 After descending half the height, the auxiliary gear 75 meshes with the rack 1022 to roll when the device housing 1 moves down along the positioning column 102, and the auxiliary gear 75 cooperates with the positioning gear 71 to push the winding wheel 72 to reel in the adjustment rope 74, so that when the device housing 1 continues to move down, the adjustment rope 74 can simultaneously pull the lightweight floating plate 6 to deflect and fold. When the deflection and folding of the lightweight floating plate 6 are completed, the device housing 1 is re-seated on the top of the device base 5.

[0037] In order to further improve the lifting effect of the light floating plate 6 on the device housing 1, as Figure 3 and Figure 7 As shown, this embodiment provides the following preferred technical solutions:

[0038] Second convex holes 601 are evenly spaced on the side wall of the lightweight floating plate 6, and the second convex holes 601 penetrate the lightweight floating plate 6. A piston disk 602 is movably engaged between the inner walls of the second convex hole 601. A hollow cylinder 603 is fixedly connected to the outer wall of the piston disk 602 near the small aperture port of the second convex hole 601. Sealing rings 604 are fixedly provided on the inner wall of the small aperture port of the second convex hole 601 and on the circumferential side wall of the piston disk 602. The sealing ring 604 on the inner wall of the small aperture port of the second convex hole 601 is movably sleeved on the outer wall of the hollow cylinder 603.

[0039] Active cavities 605 are respectively provided on the outer walls of the lightweight floating plates 6 on both sides of the second convex hole 601, and the ports of the active cavities 605 extend to the outer wall of the lightweight floating plate 6 on one side of the large-aperture port of the second convex hole 601. A reset spring 606 is fixedly connected to the inner wall of the active cavity 605 at one end away from the large-aperture port of the second convex hole 601, and a counterweight 607 is fixedly connected to the end of the reset spring 606. The counterweight 607 is small in size and weight, and only needs to be able to pull the hollow cylinder 603 to move. The counterweight 607 is movably engaged in the active cavity 605, and a traction rope 608 is fixedly connected to the outer wall of the end of the fixed end of the counterweight 607. The other end of the traction rope 608 extends through the second convex hole 601 and is fixedly connected to the outer wall of the piston disk 602 on the outside of the hollow cylinder 603.

[0040] The small-aperture port of the second convex hole 601 is arranged away from the port of the positioning groove 103, and when the return spring 606 maintains a normal relaxation state, the divergent ends of the piston disk 602 and the hollow cylinder 603 are respectively flush with the ports at both ends of the second convex hole 601. At this time, the counterweight block 607 is completely retracted into the active chamber 605.

[0041] Specifically, after the light floating plate 6 is deflected to a horizontal state, the counterweight block 607 slides out of the active cavity 605 port at the bottom of the light floating plate 6 under the action of gravity to stretch the reset spring 606, and the counterweight block 607 moves downward to pull the traction rope 608, and the traction rope 608 pulls the piston plate 602 to move upward in the second convex hole 601. After the top of the piston plate 602 contacts the sealing ring 604 provided on the inner wall at the top port of the second convex hole 601, the hollow cylinder 603 extends from the top port of the second convex hole 601 to the top of the light floating plate 6, and the piston plate 602 moves upward. An inverted cavity is formed in the internal space of the second convex hole 601 below, thereby increasing the contact area between the lightweight floating plate 6 and the accumulated water, and cooperating with the hollow tube 603 to increase the buoyancy of the lightweight floating plate 6 in the water, thereby better assisting the lightweight floating plate 6 to push the device housing 1 to float and move in the accumulated water, and maintaining the stability of the device housing 1 in the water. After the lightweight floating plate 6 is deflected and reset, under the action of the reset spring 606, the counterweight block 607 and the hollow tube 603 are automatically reset, avoiding the counterweight block 607 and the hollow tube 603 from extending out to affect the deflection and folding of the lightweight floating plate 6, which is convenient to use.

A shaft rod is arranged on the side wall of the fixed block 853, and the shaft rod is movably connected to the first rotating disk 851 and the second rotating disk 852. A movable bar 854 is fixedly connected to the bottom of the fixed block 853 on the second rotating disk 852. The bottom of the fixed block 853 on the first rotating disk 851 is movably clamped on the outer wall at the top of the movable bar 854. The fixed block 853 is fixedly connected to the outer wall of one end of the first rotating disk 851 and the second rotating disk 852. The limiting strip 855 is symmetrically arranged on the limiting column 9, and the limiting openings 91 are respectively opened on the outer walls on both sides of the limiting column 9 corresponding to the limiting strip 855.

[0046] Specifically, after the accumulated water fills and submerges the inner groove 105, the accumulated water enters the interior of the limiting cylinder 8 from the connecting port 81, and the accumulated water presses the movable disk 83 to move downward along the limiting column 9 inside the limiting cylinder 8 through gravity to compress the elastic component 82. When the movable disk 83 moves downward, the movable connecting rod 84 is used to drive the first rotating disk 851 to rotate clockwise. The first rotating disk 851 drives the limiting bar 855 to rotate and withdraw from the limiting port 91 on one side of the limiting column 9 based on the fixed block 853, and the first rotating disk 851 drives the fixed block 853 to rise in height when rotating. When rising, the fixed block 853 rotates on the outer wall of the first rotating disk 851 based on the shaft. , keeping the horizontal state of the limit bar 855 unchanged, so that the fixed block 853 slides along the top of the movable bar 854 and lifts the movable bar 854. When the movable bar 854 moves up, it cooperates with the fixed block 853 fixed at the other end to drive the second turntable 852 to rotate counterclockwise, so that the fixed block 853 on the second turntable 852 drives the limit bar 855 to rotate and withdraw from the limit opening 91 on the other side of the limit column 9, preventing the first turntable 851 from using friction to drive the second turntable 852 to rotate counterclockwise and slip, resulting in the second turntable 852 being unable to drive the limit bar 855 to rotate counterclockwise and withdraw from the limit opening 91 on the side wall of the limit column 9, so that the second turntable 852 The limiting strip 855 on the first rotating disk 851 and the second rotating disk 852 can be smoothly pulled out of the limiting opening 91 on the limiting column 9, so that when the accumulated water is immersed in the inner groove 105, the limiting strip 855 can automatically release the restriction on the limiting column 9 at the bottom of the device housing 1, and then release the restriction on the device housing 1 by the device base 5, so that the device housing 1 can float and move smoothly. When the accumulated water recedes and the device housing 1 is re-seated on the top of the device base 5, the limiting column 9 is reinserted into the limiting cylinder 8, and the accumulated water in the limiting cylinder 8 slowly drips through the drip hole, and is evaporated by the high temperature when the weather is clear, so that the limiting cylinder 8 is discharged, so that the elastic component 82 pushes The movable disk 83 moves up and resets inside the limit cylinder 8 along the limit column 9, so that the movable disk 83 uses the movable connecting rod 84 to drive the first turntable 851 and the second turntable 852 to rotate in the opposite direction. The movable bar 854 adjusts the angle of the upper limit bar 855 on the side wall of the fixed block 853 based on gravity, so that the limit bar 855 is horizontally inserted into the limit opening 91 on the limit column 9 after the turntable rotates, thereby realizing the locking of the limit bar 855 on the limit column 9, and then automatically completing the connection and locking of the two after the device housing 1 is seated on the top of the device base 5, so as to ensure the stability of the device housing 1 and the device base 5 during transportation, movement and use, and is easy to use.
