Description

Technical Field

[0001] The present invention belongs to the technical field of charging piles, and specifically relates to an automatically protected charging pile for rainstorm waterlogging. Background Art

[0002] With the wide popularization of electric vehicles, as an important energy supply facility for electric vehicles, the safety and stability of charging piles in use are becoming increasingly important. In the actual use process, the impact of rainstorm waterlogging on charging piles is particularly significant.

[0003] For the convenience of manual maintenance, the power components inside the existing charging piles are set at a low position. If a lifting mechanism is set and the power components are raised to a high position after maintenance, there may also be a situation where the staff forgets to raise the power components, lacking an automatic protection mechanism. When encountering rainstorm weather, the ground water level rises rapidly, and the water is likely to enter the interior through the ventilation holes, resulting in the internal power components being soaked by water, affecting the normal use of the charging pile, and may also cause safety accidents such as short circuits and electric leakage. After the water recedes, the charging pile cannot automatically return to the normal state, and manual inspection and debugging are required, increasing the maintenance cost and inconvenience of use.

[0004] Therefore, the existing charging piles have deficiencies in dealing with rainstorm waterlogging, and there is an urgent need for an automatically protected charging pile for rainstorm waterlogging, which can automatically protect the power components during rainstorm waterlogging to avoid damage and automatically return to normal after the water recedes, so as to improve the safety and reliability of the charging pile. Summary of the Invention

[0005] In view of this, the present invention provides an automatically protected charging pile for rainstorm waterlogging.

[0006] The technical solution is: an automatically protected charging pile for rainstorm waterlogging, including a base, an outer box with a built-in charging device is fixedly arranged above the base, a round hole is opened at the center of the bottom of the outer box, ventilation holes are opened at both the upper and lower parts of the side of the outer box, a guide rod is connected inside the outer box, a floating plate one that slides up and down is arranged on the guide rod, the top of the floating plate one is connected with a mounting plate, mounting holes are opened on the mounting plate, two mounting shells are connected to the inner wall of the outer box, electric push rods controlled by a control component are arranged inside the mounting shells, moving rods are connected to the telescopic rods of the electric push rods, sliding connections are arranged at one ends of the two moving rods close to each other with limit blocks, an elastic part one is connected between the limit blocks and the moving rods, and two limit holes are opened on the mounting plate.

[0007] Further, the control component includes a fixed cylinder, a connection shell, an induction part and a floating plate two. A fixed cylinder is connected to the inner bottom of the outer box at the position of the round hole, a connection shell with a built-in pressure sensor is connected to the top of the fixed cylinder, the bottom of the pressure sensor has an induction part located inside the fixed cylinder, and the bottom of the induction part is connected with a floating plate two.

[0008] Further, the charging device includes two charging guns, two charging cables, and a control panel. The electric push rod and the pressure sensor are both electrically connected to the control panel.

[0009] Further, the bottom surfaces of the limiting blocks are all inclined planes, and the limiting holes are used for the limiting blocks to extend into.

[0010] Further, the automatic protection type charging pile for rainstorm waterlogging also includes sliding rods. Two sliding rods extending into the fixed cylinder are slidably connected to the connecting shell. The sliding rods slidably penetrate through the second floating plate. The tops of the two sliding rods are connected to the bottom of the first floating plate. A third floating plate is commonly connected between the bottoms of the two sliding rods. The inner wall of the bottom end of the fixed cylinder has an inwardly protruding annular portion, and the annular portion is used to limit the descending stroke of the third floating plate. A filter cover is connected to the bottom of the fixed cylinder.

[0011] Further, the automatic protection type charging pile for rainstorm waterlogging also includes connecting rods. Two connecting rods are connected to the upper part of the mounting plate. Two fixed rods are connected to the outer wall of the outer box. Limiting plates that slide up and down are provided on the fixed rods. An elastic member II is connected between the limiting plates and the fixed rods. Limiting grooves for the charging cables to be embedded are opened at the mutually remote ends of the two limiting plates. Through holes for the charging cables to pass through are opened in the middle of the limiting plates. Two guide wheels are rotatably connected to the lower part of the outer wall of the outer box. Pulling ropes that bypass the guide wheels are respectively connected between the two connecting rods and the two limiting plates. When the connecting rods rise along with the mounting plate, the pulling ropes will pull the limiting plates to descend synchronously.

[0012] Further, the automatic protection type charging pile for rainstorm waterlogging also includes guide strips. Two pairs of guide strips are connected to the upper part of the inner wall of the outer box. Lifting baffles that slide are provided between each pair of guide strips. The lifting baffles are used to block the ventilation holes at the upper part of the outer box. Contact blocks are connected to the mutually close sides of the two lifting baffles. When the mounting plate rises along with the first floating plate, the mounting plate will push the contact blocks to rise.

[0013] Further, the automatic protection type charging pile for rainstorm waterlogging also includes a filter screen. The filter screen is installed on the inner wall of the outer box, and the filter screen covers the ventilation holes at the lower part of the outer box.

[0014] The beneficial effects are as follows: 1. When the liquid level of rainstorm waterlogging gradually rises, water enters the outer box and the fixed cylinder. The second floating plate rises, and the sensing part senses an increase in pressure. Under the cooperation of the pressure sensor and the control panel, the electric push rod drives the moving rod to move. The limiting block abuts against the side surface of the mounting plate. Under the action of buoyancy, the first floating plate and the mounting plate move upward, and the limiting block extends into the limiting hole, so that the mounting plate, the first floating plate, and the power components are stably maintained at a high position. It has an automatic protection function and automatically returns to normal after the waterlogging recedes, improving safety and reliability.

[0015] 2. The rising mounting plate drives the connecting rods to rise. The connecting rods pull the pulling ropes, and the pulling ropes pull the limiting plates to slide downward. The downward-moving limiting plates limit the charging cables, reducing the impact of flood water on the charging cables and avoiding the problem of the charging cables getting entangled.

[0016] 3. The rising mounting plate pushes the contact block to rise, driving the lifting baffle to rise along the guide strip. The lifting baffle blocks the ventilation holes on the upper side to prevent heavy rain from entering the ventilation holes on the upper side, thereby improving the waterproof performance.

DETAILED DESCRIPTION

[0027] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1: An automatic protection type charging pile for rainstorm waterlogging. Refer to Figures 1-7 , which includes a base 1, an outer box 2, guide rods 3, a first floating plate 4, a mounting plate 5, a mounting shell 6, a control component, a moving rod 7 and a limiting block 8. An outer box 2 with an in-built charging device is fixedly arranged above the base 1. The charging device is a prior art, specifically including two charging guns 21, two charging cables 22 and a control panel 23; As Figure 3 shown, the middle of the top surface of the base 1 is concave downward, the middle of the bottom surface of the outer box 2 is concave upward, a circular hole 20 is opened at the center of the bottom of the outer box 2, ventilation holes 24 are opened at both the upper and lower parts of the side surface of the outer box 2, and the ventilation holes 24 play a role in ventilation and heat dissipation. Guide rods 3 are connected at the four corners inside the outer box 2. A first floating plate 4 that slides up and down is arranged among the four guide rods 3. The top of the first floating plate 4 is connected with a mounting plate 5. A row of mounting holes 50 are opened on both the left and right sides of the mounting plate 5, and the mounting holes 50 are used for mounting electrical components. Mounting shells 6 are connected to both the left and right sides of the inner wall of the outer box 2. Electric push rods controlled by the control component are built in the mounting shells 6. Moving rods 7 are connected to the telescopic rods of the electric push rods. Limiting blocks 8 are slidably connected to the ends of the two moving rods 7 that are close to each other. A first elastic member is fixedly connected between the limiting block 8 and the moving rod 7. The first elastic member is specifically a spring. Limiting holes 80 are opened on both the left and right sides of the mounting plate 5; The bottom surfaces of the limiting blocks 8 are inclined surfaces 81 to reduce the friction force when the limiting blocks 8 contact the mounting plate 5. The limiting holes 80 are used for the limiting blocks 8 to extend into.

[0029] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 , the control component includes a fixed cylinder 61, a connecting shell 62, an induction part 63 and a second floating plate 64. A fixed cylinder 61 is fixedly connected to the inner bottom of the outer box 2 at the circular hole 20. A connecting shell 62 with a built-in pressure sensor is connected to the top of the fixed cylinder 61. The bottom of the pressure sensor has an induction part 63 located inside the fixed cylinder 61. The bottom of the induction part 63 is connected with a second floating plate 64. The electric push rod and the pressure sensor are both electrically connected to the control panel 23.

[0030] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 7, the automatic protection type charging pile for rainstorm waterlogging also includes a sliding rod 91, a third floating plate 92 and a filter cover 93. Two sliding rods 91 extending into the inside of the fixed cylinder 61 are slidably connected to the connecting shell 62. The sliding rods 91 slidably penetrate through the second floating plate 64. The tops of the two sliding rods 91 are fixedly connected to the bottom of the first floating plate 4. A third floating plate 92 is fixedly connected between the bottoms of the two sliding rods 91. The inner wall of the bottom end of the fixed cylinder 61 has an inwardly protruding annular portion 60, and the annular portion 60 is used to limit the downward stroke of the third floating plate 92. A filter cover 93 is connected to the bottom of the fixed cylinder 61.

[0031] Reference Figure 2 , the automatic protection type charging pile for rainstorm waterlogging also includes a filter screen 12. Filter screens 12 are installed on the lower parts of the left and right sides of the inner wall of the outer box 2, and the filter screens 12 cover the ventilation holes 24 at the lower part of the outer box 2.

[0032] The power components of the charging device are installed on the mounting plate 5. By pulling out the charging gun 21, under the energizing action of the charging cable 22 and the control action of the control panel 23, the charging gun 21 can be used to charge an electric vehicle, and the ventilation holes 24 play a role in ventilation and heat dissipation.

[0033] When there is rainstorm waterlogging, the liquid level of the ground water gradually rises. The water enters the inside of the outer box 2 through the lower ventilation holes 24, and the water is filtered by the filter screen 12. The water will also enter the inside of the fixed cylinder 61 through the round holes 20, and the water is filtered by the filter cover 93, so as to prevent large foreign objects from entering the outer box 2 and the fixed cylinder 61. The water flows through the gap between the third floating plate 92 and the inner wall of the fixed cylinder 61 to the upper side of the third floating plate 92. When the liquid level inside the fixed cylinder 61 reaches the height of the second floating plate 64, under the action of buoyancy, the second floating plate 64 rises, and the buoyancy of the second floating plate 64 increases the pressure sensed by the sensing part 63 until the pressure sensed by the sensing part 63 reaches the set value. Under the cooperation of the pressure sensor and the control panel 23, the control panel 23 controls the electric push rod to drive the moving rod 7 to move towards the mounting plate 5, driving the limiting block 8 to move towards the mounting plate 5. When the limiting block 8 contacts the mounting plate 5, the limiting block 8 stops moving, while the moving rod 7 continues to move, the first elastic member deforms, and the limiting block 8 abuts against the side of the mounting plate 5.

[0034] Meanwhile, the liquid level inside the outer box 2 gradually rises. When the liquid level inside the outer box 2 rises to the height of the first floating plate 4, the buoyancy force received by the first floating plate 4 is greater than the total gravity of the first floating plate 4, the mounting plate 5, and the electrical components. Under the action of the buoyancy force, the first floating plate 4 and the mounting plate 5 move upward, driving the slide rod 91 and the third floating plate 92 upward. When the limiting hole 80 aligns with the limiting block 8, under the action of the first elastic member, the limiting block 8 extends into the limiting hole 80, thereby fixing the position of the mounting plate 5 through the two limiting blocks 8, so that the mounting plate 5, the first floating plate 4, and the electrical components are stably maintained at a high position to avoid violent shaking of the mounting plate 5, the first floating plate 4, and the electrical components, thereby protecting the electrical components. At this time, the third floating plate 92 does not contact the second floating plate 64.

[0035] When the accumulated water gradually recedes and the liquid level gradually drops, when the liquid level inside the fixed cylinder 61 is lower than the second floating plate 64, under the action of gravity, the second floating plate 64 descends, and the pressure sensed by the sensing portion 63 decreases. With the cooperation of the pressure sensor and the control panel 23, the control panel 23 controls the electric push rod to drive the moving rod 7 to move away from the mounting plate 5, driving the limiting block 8 away from the limiting hole 80. Under the action of gravity, the mounting plate 5, the first floating plate 4, and the electrical components gradually drop as the liquid level inside the outer box 2 decreases, driving the slide rod 91 and the third floating plate 92 to descend. The third floating plate 92 pushes out a small amount of sediment below the fixed cylinder 61 to prevent the fixed cylinder 61 from being blocked until the third floating plate 92 contacts the annular portion 60.

[0036] In this way, during a heavy rainstorm, the mounting plate 5, the first floating plate 4, and the electrical components can be automatically and stably maintained at a high position. After the accumulated water recedes, the mounting plate 5, the first floating plate 4, and the electrical components automatically descend, having an automatic protection function and can automatically return to normal after the accumulated water recedes, improving safety and reliability.

[0037] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8, further comprising a connecting rod 101, a fixing rod 102, a limiting plate 103, a guide wheel 105 and a pulling rope 106. Two symmetrical connecting rods 101 are fixedly connected to the front side of the upper part of the mounting plate 5. Fixing rods 102 are welded to the left and right sides of the outer wall of the outer box 2. Limiting plates 103 that can slide up and down are provided on the fixing rods 102. A second elastic member is fixedly connected between the limiting plate 103 and the fixing rod 102. The second elastic member is specifically a spring. Limiting grooves 104 for the charging cable 22 to be inserted into are formed at one end of the two limiting plates 103 away from each other. Through holes are formed in the middle of the limiting plates 103. The charging cable 22 passes through the through holes. Guide wheels 105 are rotatably connected to the lower parts of the left and right sides of the outer wall of the outer box 2. Pulling ropes 106 that bypass the guide wheels 105 are respectively connected between the two connecting rods 101 and the two limiting plates 103. When the connecting rod 101 rises with the mounting plate 5, the pulling rope 106 will pull the limiting plate 103 to descend synchronously.

[0038] When the charging gun 21 is pulled out, the charging cable 22 disengages from the limiting groove 104. When the charging gun 21 is plugged back in, the end of the charging cable 22 is inserted into the limiting groove 104. When the mounting plate 5 rises, the mounting plate 5 drives the connecting rod 101 to rise. Under the guiding action of the guide wheel 105, the connecting rod 101 pulls the pulling rope 106, and the pulling rope 106 pulls the limiting plate 103 to slide downward. The second elastic member deforms, and the descending limiting plate 103 limits the charging cable 22, reducing the influence of water on the charging cable 22 and avoiding the problem of the charging cable 22 being entangled.

[0039] Embodiment 3: On the basis of Embodiment 2, referring to Figure 2 , Figure 3 and Figure 9 , further comprising a guide strip 111, a lifting baffle 112 and a contact block 113. A pair of guide strips 111 are fixedly connected to the upper parts of the left and right sides of the inner wall of the outer box 2. A lifting baffle 112 that can slide up and down is provided between each pair of guide strips 111. The lifting baffle 112 is used to block the ventilation holes 24 in the upper part of the outer box 2. Contact blocks 113 are fixedly connected to one side of the two lifting baffles 112 close to each other. When the mounting plate 5 rises with the first floating plate 4, the mounting plate 5 will push the contact block 113 to rise.

[0040] When the mounting plate 5 rises, the mounting plate 5 will push the contact block 113 to rise, driving the lifting baffle 112 to rise along the guide strip 111. The lifting baffle 112 blocks the upper ventilation holes 24, preventing rainstorm from entering the upper ventilation holes 24 and improving the waterproof performance. When the mounting plate 5 descends, the lifting baffle 112 and the contact block 113 drop to the initial position by gravity.

[0041] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
