Description

Technical Field

[0001] The present invention relates to the field of liquid-cooled charging piles, and in particular to a liquid-cooled charging pile with an insulating protection structure. Background Art

[0002] Liquid-cooled charging pile is a kind of charging pile that uses liquid circulation cooling to cool the battery. It mainly adopts annular heat pipe technology, and through the circulation of heat-conducting liquid, the temperature of the charging pile battery is always kept within a suitable range, thereby achieving the purpose of fast charging.

[0003] Because the liquid-cooled charging pile uses liquid as a cooling medium to cool the charging pile, its own insulation protection is more important. Usually, insulating materials are set between the various electrical structures, and the joint structures in the liquid cooling system need to be strictly sealed. Therefore, the existing liquid-cooled charging pile has good insulation protection performance. However, there are still shortcomings in actual use: the liquid cooling system is composed of fins and pipes, and the coolant flows inside the pipes. Therefore, there is a large temperature difference between the outside temperature and the pipe temperature, which makes it easy for water droplets to condense on the pipes. After the water droplets drip into the charging pile, it will not only directly affect the internal circuit structure of the charging pile, but also cause certain corrosion to its insulating materials, resulting in a reduction in the service life of the charging pile body.

[0004] Therefore, it is necessary to provide a new liquid-cooled charging pile with an insulating protection structure to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a liquid-cooled charging pile with an insulating protection structure.

[0006] The liquid-cooled charging pile with an insulating protective structure provided by the present invention comprises a charging pile body, a vent on the side of the charging pile body, a fan installed on the back of the charging pile body, and a liquid cooling system installed inside the charging pile body and near the vent; The liquid cooling system is flexibly installed inside the charging pile body; A vibrating member is also fixed near the middle of the liquid cooling system, and the vibrating member includes a rotatable cylindrical shaft, and an impeller corresponding to the position of the air hole and driven to rotate by airflow is fixed on the circumferential outer wall of the cylindrical shaft, and an eccentric counterweight is also fixed; A drainage bucket is fixed near the bottom of the liquid cooling system, a drainage pipe is fixed at the bottom of the drainage bucket, the other end of the drainage pipe is passed through and extends to the outside of the charging pile body to drain the accumulated water, and a plurality of buffer parts are fixed on the inner wall of the drainage bucket.

[0007] Preferably, the pores are Z-shaped, and the holes located on the outer wall of the charging pile body are located lower than the holes located on the inner wall.

[0008] Preferably, the liquid cooling system comprises two groups of symmetrically arranged mounting frames, a plurality of fins distributed vertically and inclined are welded and fixed between the two groups of mounting frames, and row pipes are passed through and fixed on the fins.

[0009] Preferably, a tripod is welded and fixed on the mounting frame near the lower end, a vertically arranged sliding rod passes through the tripod, and the tripod and the sliding rod are slidably connected, a first mounting seat is welded and fixed to the lower end of the sliding rod, and the first mounting seat is welded and fixed inside the charging pile body, and a spring for supporting the liquid cooling system is also sleeved on the sliding rod, and both ends of the spring are respectively pressed against the tripod and the first mounting seat.

[0010] Preferably, mounting plates are bolted to both groups of the mounting frames, a strip frame is integrally connected between the two mounting plates, a second mounting seat is welded and fixed to the strip frame, and a positioning shaft is vertically welded to one side of the second mounting seat.

[0011] Preferably, the cylindrical shaft is mounted on the positioning shaft via a bearing.

[0012] Preferably, the drain bucket is screwed to the mounting frame, the upper end of the drain bucket has an opening and is located directly below the fin, the inner bottom of the drain bucket has an inclined surface, and the drain pipe is installed at the lowest point of the corresponding inclined surface.

[0013] Preferably, the buffer component includes a plurality of positioning rods, the positioning rods are vertically bonded to the inner wall of the drainage bucket, an intercepting net is sleeved on the positioning rods, and a folding support tube for supporting the intercepting net is also sleeved, and the intercepting net has a certain displacement floating amount through the extension and retraction of the folding support tube.

[0014] Preferably, the folding support tube and the intercepting net are both made of rubber and are integrally formed.

[0015] Compared with the related art, the liquid-cooled charging pile with an insulating protection structure provided by the present invention has the following beneficial effects: 1. The liquid cooling system is flexibly installed inside the charging pile body, and a vibrator is arranged on it. The vibrator can drive the entire liquid cooling system to vibrate together, so as to shake off the water droplets condensed on the drain pipe. A drainage bucket is installed at the lower end of the liquid cooling system. The shaken water droplets can drip into the drainage bucket and then be discharged through the drainage pipe, which has a good protective effect on the charging pile body; 2. A fan is also added inside the charging pile body. When the fan is running, it can accelerate the air flow rate inside the charging pile body, thereby accelerating the evaporation rate of water droplets on the drain pipe and improving the cooling effect. At the same time, during the rapid flow of air, the air flow can act on the impeller to drive the impeller to rotate, and then drive the eccentric counterweight block to rotate together through the barrel shaft. When the eccentric counterweight block rotates, centrifugal force can be generated, which can drive the liquid cooling system to vibrate. Therefore, it does not require an independent power structure when vibrating, which can reduce the production cost and energy consumption of the device; 3. A buffer is also provided inside the drain bucket. When water droplets fall into the drain bucket, the buffer can be used to buffer the dripping water droplets, thereby avoiding splashing of water droplets and achieving a higher protective effect.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] See also Figures 1 to 9 An embodiment of the present invention provides a liquid-cooled charging pile with an insulating protection structure. The liquid-cooled charging pile with an insulating protection structure includes a charging pile body 1, a liquid cooling system 2, a vibrating member 3, a drainage bucket 4, and a buffer member 42 arranged inside the drainage bucket 4.

[0021] It should be noted that: in the device, a liquid cooling system 2 is arranged inside the charging pile body 1 to perform heat dissipation operation on the charging pile body 1, and a vibrator 3 and a drainage bucket 4 are installed on the liquid cooling system 2. When the vibrator 3 is in operation, it can drive the liquid cooling system 2 to vibrate, and under the action of vibration, it can shake off the water droplets generated on the liquid cooling system 2, so that the water droplets fall into the drainage bucket 4, are concentrated by the drainage bucket 4, and finally are discharged through the drainage pipe 41, so that the formed water droplets can be better processed to prevent the water droplets from falling into the charging pile body 1, and have a better protective effect on the charging pile body 1; At the same time, a buffer member 42 is also provided inside the drainage bucket 4 , and the buffer member 42 can buffer the water droplets dripping into the drainage bucket 4 , thereby preventing the water droplets from splashing, and further improving the protection of the charging pile body 1 .

[0022] For the charging pile body 1; See also Figure 1 , Figure 2 and Figure 4 There is an air hole 11 on the side of the charging pile body 1, and a fan 12 is installed on the back side of the charging pile body 1. The air hole 11 is Z-shaped, and the hole located on the outer wall of the charging pile body 1 is lower than the hole located on the inner wall.

[0023] It should be noted that: for the charging pile body 1, there are air holes 11 on both sides, through which the internal heat can be discharged for heat dissipation. At the same time, a fan 12 is also installed on the back side of the charging pile body 1. The fan 12 is preferably an exhaust type. When in use, the exhaust fan 12 can prevent the heat generated by itself from entering the charging pile body 1, and will not affect the heat dissipation of the charging pile body 1. Moreover, when external cold air enters the charging pile body 1, the liquid cooling system 2 can be cooled, and the charging pile body 1 can also be cooled by air, further improving the efficiency of heat dissipation; The air hole 11 is Z-shaped, and the height of the hole located on the outer wall of the charging pile body 1 is lower than the height of the hole located on the inner wall, which can meet the normal circulation of airflow and also has a certain waterproof effect. Therefore, when used on rainy days, it can prevent rainwater from rushing through the air hole 11 into the interior of the charging pile body 1, and it can also prevent some solid impurities from entering the interior of the charging pile body 1, which will have a better protection effect on the charging pile body 1.

[0024] For liquid cooling system 2; See also Figure 3 and Figure 5 , the liquid cooling system 2 is elastically installed inside the charging pile body 1 and close to the air hole 11; The liquid cooling system 2 includes two groups of symmetrically arranged mounting frames 21, and a plurality of fins 22 distributed up and down and inclined are welded and fixed between the two groups of mounting frames 21. The fins 22 are penetrated and fixed with row pipes 23, and a tripod 24 is welded and fixed near the lower end of the mounting frame 21. A vertically arranged sliding rod 25 passes through the tripod 24, and the tripod 24 and the sliding rod 25 are slidably connected. A first mounting seat 26 is welded and fixed to the lower end of the sliding rod 25, and the first mounting seat 26 is welded and fixed to the inside of the charging pile body 1. A spring 27 for supporting the liquid cooling system 2 is also sleeved on the sliding rod 25, and the two ends of the spring 27 are respectively pressed against the tripod 24 and the first mounting seat 26.

[0025] It should be noted that the liquid cooling system 2 is only a part of the complete system, including only the fins 22 and the row pipes 23 (the complete liquid cooling system is a mature prior art and is not described in detail here). The cooling liquid flows through the row pipes 23 to cool the charging pile body 1. For the installation of the liquid cooling system 2, a bracket 24 is provided on the side of the mounting frame 21 and near the bottom. A slide bar 25 is provided on the bracket 24 to position the mounting frame 21. A spring 27 is sleeved on the slide bar 25 to support the mounting frame 21. The spring 27 can be extended and retracted, so that the mounting frame 21 has a certain displacement floating amount, so that it can cooperate with the vibrating member 3 to realize the vibration effect. The exhaust pipe 23 corresponds to the position of the air hole 11 , so when the fan 12 is used to accelerate the airflow, the airflow can directly act on the exhaust pipe 23 , which can accelerate the evaporation of water droplets on the exhaust pipe 23 , and also has a certain protective effect, and can also accelerate the heat dissipation of the fins 22 .

[0026] For the vibrating member 3; See also Figure 5 and Figure 6 The vibrating member 3 includes two groups of mounting plates 31, which are respectively bolted to the two groups of mounting frames 21, and a strip frame 32 is integrally connected between the two mounting plates 31. A second mounting seat 33 is welded and fixed to the strip frame 32, and a positioning shaft 34 is vertically welded to one side of the second mounting seat 33. A rotatable cylindrical shaft 35 is connected to the bearing on the positioning shaft 34. An impeller 36 corresponding to the position of the air hole 11 and driven to rotate by airflow is fixed to the circumferential outer wall of the cylindrical shaft 35, and an eccentric counterweight 37 is also fixed.

[0027] It should be noted that: in the vibrating member 3, the mounting plate 31 and the strip frame 32 form a bracket structure, which is fixed on the mounting frame 21 to ensure its own stability. At the same time, the strip frame 32 itself has a relatively small area, so it will not affect the circulation of the airflow. The strip frame 32 is used as the mounting base, and a second mounting seat 33 is fixed on it. The second mounting seat 33 is fixed with a positioning shaft 34. The positioning shaft 34 is installed with a cylindrical shaft 35 through a bearing, so that the cylindrical shaft 35 can rotate, and an impeller 36 is arranged outside the cylindrical shaft 35, and the impeller 36 is directly opposite to the cylindrical shaft 35. According to the position of the air hole 11, during the process of air flow, the air flow can directly act on the impeller 36, generating a force on the impeller 36 to drive the impeller 36 to rotate, and an eccentric counterweight 37 is also fixed on the cylinder shaft 35. When the eccentric counterweight 37 rotates, centrifugal force is generated. Under the action of the centrifugal force, the mounting frame 21 can vibrate, so that the water drops on the drain pipe 23 can be shaken off, and the vibration of the vibrating member 3 does not require an independent driving source, so no energy consumption is generated in actual use, and the production cost of the device can be reduced; The fins 22 are inclined so that water drops on the drainage pipes 23 can slide down along the surface of the fins 22, thereby improving the drainage effect.

[0028] For the drainage bucket 4 and the buffer 42; See also Figure 7 , Figure 8 and Fig. 9 The drain bucket 4 is screwed to the mounting frame 21. The upper end of the drain bucket 4 has an opening and is located directly below the fin 22. The bottom of the drain bucket 4 has an inclined surface. A drain pipe 41 is fixed at the lowest point of the inclined surface at the bottom of the drain bucket 4. The other end of the drain pipe 41 is extended to the outside of the charging pile body 1. The buffer member 42 includes a plurality of positioning rods 421, which are vertically bonded to the inner wall of the drainage bucket 4. An interception net 423 is sleeved on the positioning rods 421, and a folding support tube 422 for supporting the interception net 423 is also sleeved. The folding support tube 422 is telescopically extended to allow the interception net 423 to have a certain displacement floating amount. The folding support tube 422 and the intercepting net 423 are both made of rubber and are integrally formed.

[0029] It should be noted that: the drain bucket 4 is screwed to the mounting frame 21, so when the mounting frame 21 vibrates, the drain bucket 4 will also vibrate together. When water drops from the drain pipe 23 fall into the drain bucket 4, the vibration will make it easier to guide the accumulated water into the drain pipe 41 and drain the accumulated water through the drain pipe 41. In addition, the bottom of the drain bucket 4 is an inclined surface, which also has a drainage effect. The buffer member 42 is arranged on the inner wall of the drain bucket 4, and is used for buffering the water drops dripping into the drain bucket 4, that is, the water drops will directly drip onto the interception net 423, and the interception net 423 can directly buffer the water drops. At the same time, the interception net 423 is supported by a folding support tube 422, and the folding support tube 422 can have a telescopic effect. Moreover, the folding support tube 422 and the interception net 423 are both made of rubber material, and both have a certain elasticity, which can better buffer the water drops, thereby avoiding water droplet splashing and improving the protection of the charging pile body 1.

[0030] The specific usage process of the device is as follows: (1) Operation and use of liquid cooling system; In the liquid cooling system 2, the coolant is driven to flow by a water pump to absorb the heat generated inside the charging pile body 1, and then the coolant flows to the inside of the drain pipe 23, and the absorbed heat is conducted out through the fins 22 to achieve cooling of the coolant. In this process, the fan 12 can be turned on. When the fan 12 is in operation, the external cold air enters the inside of the charging pile body 1 from the air hole 11. The drain pipe 23 is close to the air hole 11, so the drain pipe 23 and the fin 22 can be directly cooled by air, thereby improving the heat dissipation efficiency; (2) The vibrating element is driven by airflow to operate; After the airflow passes through the fins 22, it can directly act on the impeller 36. Under the action of the airflow, the impeller 36 can be driven to rotate, thereby driving the barrel shaft 35 to rotate together. The barrel shaft 35 is also provided with an eccentric counterweight 37. Therefore, when the barrel shaft 35 rotates, the eccentric counterweight 37 can be driven to rotate together. When the eccentric counterweight 37 rotates, centrifugal force is generated. The mounting frame 21 itself is supported by the spring 27. Therefore, under the action of the centrifugal force, the mounting frame 21 can vibrate, thereby shaking off the water droplets attached to the drain pipe 23. (3) Collecting and draining water through drainage buckets; The water drops shaken off from the drain pipe 23 will directly fall into the drain bucket 4, and a buffer part 42 is provided inside the drain bucket 4 to buffer the dripping water drops, that is, the dripping water drops can directly drip onto the interception net 423, and the interception net 423 is made of rubber material, which can buffer the water drops. At the same time, the interception net 423 is supported by a folding support tube 422, and the folding support tube 422 can be retracted and is also made of rubber material. When the interception net 423 is impacted by water drops, the folding support tube 422 can also produce a certain deformation, thereby further enhancing the buffering effect; the water concentrated in the drain bucket 4 can finally be discharged through the drain pipe 41.
