Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to an electrical control switch cabinet for a charging pile. Background Art

[0002] The charging pile electrical control switch cabinet is an electrical device used to control and protect the power supply of the charging pile. The working principle of the charging pile electrical control switch cabinet is based on the control and protection mechanism of the circuit. When the vehicle is connected to the charging pile and starts charging, the control switch cabinet first detects the status and demand of the vehicle battery through the measurement circuit, and then sends instructions to the actuators such as the contactor through the control circuit according to the preset charging strategy, adjusts the charging current and voltage, and starts charging the vehicle.

[0003] Charging piles are often used in public areas, commercial center parking lots, residential parking lots, and highway service areas. When the charging pile needs to meet the demand for fast charging, the electrical control switch cabinet is required to provide high-power power output to ensure that the vehicle obtains sufficient power in a short time. Then the interior of the electrical control switch cabinet will also quickly generate a lot of heat, so the charging pile electrical control switch cabinet needs to have a good heat dissipation function.

[0004] Existing electrical control switch cabinets for charging piles generally use heat dissipation holes to dissipate heat. However, electrical control switch cabinets are generally installed near outdoor charging piles. Vehicles driving near the electrical control switch cabinets and regular cleaning of nearby roads will stir up dust, which can easily penetrate the heat dissipation holes and enter the cabinet. Existing electrical control switch cabinets for charging piles use heat dissipation holes to ensure heat dissipation while it is difficult to ensure good dust prevention effects, which is not conducive to the use of electrical control switch cabinets for charging piles.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1 like Figures 1 to 9As shown, a charging pile electrical control switch cabinet comprises an outer shell 1, the top and bottom of the outer shell 1 are respectively sealed and fixedly connected with a top cover 2 and a bottom cover 3, a cabinet door 4 is hinged on the front of the outer shell 1, the outer shell 1 is a sealed structure, and a sealing ring is inlaid on the outer side of the cabinet door 4, the cabinet door 4 and the outer shell 1 are sealed by a sealing ring, the sealing ring is made of high temperature resistant material and inlaid around the outer side of the cabinet door 4, the outer shell 1, the top cover 2, the bottom cover 3 and the cabinet door 4 are all made of bent metal materials, a plurality of heat dissipation holes 5 are fixedly connected at equal intervals on both sides of the outer shell 1, a driving assembly is fixedly connected on both sides of the inner wall of the outer shell 1, and a sealing plate 6 corresponding to the heat dissipation holes 5 is inserted on the driving assembly, and a plurality of adjustment plates 7 are vertically fixedly connected inside the outer shell 1, the adjustment plates 7 are at least two groups and are vertically fixed, and at the same time, long strip holes are fixedly connected on the adjustment plates 7 at equal intervals, and a mounting plate 8 is detachably fixedly connected on the adjustment plate 7, and the mounting plate 8 is horizontally arranged and has a circular hole that cooperates with the long strip holes on the adjustment plate 7 for positioning, and the adjustment plate 7 is detachably fixed to the mounting plate 8 by bolts, so that the mounting plate 8 can be adjusted up and down on the adjustment plate 7, thereby ensuring that the installation position of the electric cabinet control body 9 and the charging pile can be adjusted, thereby ensuring the versatility of the switch cabinet, which realizes fire prevention by monitoring the concentration of smoke. The mounting plate 8 is fixedly connected to the electric cabinet control body 9 and the protection box 10, and the electric cabinet control body 9 and the charging pile can be fixed on the mounting plate 8. The protection box 10 is fixedly connected to the inside of the power-off self-starting component and the battery 11, and the outside of the protection box 10 is fixedly connected to the smoke sensor 12. The smoke sensor 12 is electrically connected to the electric cabinet control body 9, and its working principle is the prior art, and no further explanation is given here. The top cover 2 is fixedly connected to a power converter 13 and an air pump 14 electrically connected to the electric cabinet control body 9, and the air pump 14 is electrically connected to the battery 11 through the power-off self-starting component, and the top cover 2 is respectively penetrated with an inlet 15 and an outlet 16, and the top of the bottom cover 3 is fixedly connected to a fire extinguishing component facing the electric cabinet control body 9.

[0022] like Figures 1 to 7As shown, the driving assembly includes a plurality of parallel rotating shafts 21 and a driving motor 22 fixed to the inner wall of the outer shell 1, both ends of the rotating shaft 21 are connected to the inner wall of the outer shell 1 through a first bearing seat 23, a sealing plate 6 is fixedly inserted in the middle of the rotating shaft 21, one end of the rotating shaft 21 is fixedly connected to a worm gear 24, the output end of the driving motor 22 is fixedly connected to a worm 25 meshing with the worm gear 24, the meshing of the worm gear 24 and the worm gear 25 is mechanically self-locking, and the worm gear 25 is connected to the inner wall of the outer shell 1 through a second bearing seat 26, the driving motor 22 is electrically connected to the electric cabinet control body 9, and one end of the worm gear 25 is connected to the inner wall of the outer shell 1. A first elastic member 27 is connected, and the drive motor 22 has a self-locking function when powered on. After the drive motor 22 is started, it can drive the worm 25 to rotate a fixed number of circles and make the rotating shaft 21 rotate at least 90 degrees, and the rotation angle of the rotating shaft 21 does not exceed 120 degrees. This can ensure that the sealing plate 6 is fully opened, so that the heat dissipation effect of the heat dissipation hole 5 is optimal. At the same time, the meshing of the worm wheel 24 and the worm 25 has mechanical self-locking. In actual use, the worm 25 can actively drive the worm wheel 24 to rotate, but the worm wheel 24 cannot drive the worm 25 to rotate in the opposite direction. This can ensure the stability of the opening angle of the sealing plate 6 and effectively improve the service life of the drive motor 22.

[0023] The first elastic member 27 is always in a contracted state, and the torque of the drive motor 22 is greater than the elastic force of the first elastic member 27. When the drive motor 22 is powered off and loses the self-locking function, the first elastic member 27 can drive the worm 25 to actively reverse and ensure that the sealing strip 28 is tightly fitted with the heat dissipation hole 5. One situation in which the drive motor 22 is powered off is an external power failure, and another situation is a power failure caused by an internal failure of the electrical cabinet control body 9 itself. In the event of a fire, the charging pile cannot be used in these two situations. Therefore, the first elastic member 27 drives the sealing plate 6 to actively reverse and seal, which can play an active dust prevention or active sealing and fire extinguishing effect.

[0024] like Figure 8As shown, the power-off self-starting components include two groups of support blocks 29 fixedly connected to the bottom end of the protective box 10, and the tops of the two groups of support blocks 29 are horizontally penetrated and fixedly connected with a first connector 30 and a second connector 31, one end of the first connector 30 is electrically connected to one pole of the battery 11, one end of the second connector 31 is connected in series with the air pump 14 and electrically connected to the other pole of the battery 11, and the second connector 31 is rotatably connected to the third connector 32 at one end close to the first connector 30, and a second elastic member 33 is connected between the third connector 32 and the inner bottom wall of the protective box 10, and the bottom of one side of the third connector 32 A magnet 34 is fixedly connected, and an iron core 35 fixedly connected to the bottom wall of the protective box 10 is provided directly below the magnet 34. A coil 36 is wound and fixedly connected to the outer side of the iron core 35. The coil 36 is electrically connected to the electric cabinet control body 9. When the coil 36 is energized, the iron core 35 generates magnetism, and the end of the iron core 35 and the magnet 34 that are close to each other have the same magnetism and repel each other. At this time, the third connector 32 and the first connector 30 are in a disconnected state. When the coil 36 is energized, the repulsive force between the iron core 35 and the magnet 34 is greater than the pulling force of the second elastic member 33, and the material of the third connector 32 is non-magnetic material copper or aluminum.

[0025] In this embodiment, the charging pile is fixed inside the outer shell 1 by using the adjustment plate 7 and the mounting plate 8, and the control chip is fixedly connected inside the electric cabinet control body 9, and the electric cabinet control body 9 is electrically connected to the external power supply through the inlet 15 and the outlet 16. In actual use, the electric cabinet control body 9 controls the drive motor 22 to rotate forward, and the drive motor 22 rotates forward to drive the worm 25 to rotate. At this time, the worm 25 drives the worm wheel 24 to rotate, and the worm wheel 24 drives the rotating shaft 21 to rotate. At the same time, the rotating shaft 21 drives the sealing plate 6 to rotate a certain angle, so that the sealing strip 28 leaves the heat dissipation hole 5, that is, the heat dissipation hole 5 is in In the on state, when the charging pile is in use, the heat dissipation holes 5 are opened and the heat dissipation fan 17 is started, so that the heat can be effectively dissipated. On the contrary, when the charging pile is not in use, the electric cabinet control body 9 controls the driving motor 22 to reverse, and the rotating shaft 21 drives the sealing plate 6 to reverse and reset, so that the sealing strip 28 can close the heat dissipation holes 5. In addition, in actual use, a buzzer or a warning light can be connected in series between the first connector 30 or the second connector 31 and the battery 11. In this way, when the electric cabinet control body 9 fails and the power is cut off, the battery 11 can be used to start the buzzer or the warning light, thereby playing a warning role and reminding personnel to check the fault.

[0026] It should be taken into account that when a fire occurs inside the cabinet and the cabinet control body 9 is not powered off, the smoke sensor 12 detects smoke and transmits a signal to the cabinet control body 9, and the cabinet control body 9 controls the drive motor 22 to reverse, thereby using the sealing strip 28 to seal the heat dissipation hole 5. At the same time, the cabinet control body 9 controls the air pump 14 to start, and the air pump 14 extracts the gas inside the cabinet, thereby forming a low-pressure and low-oxygen environment inside the cabinet, which can effectively extinguish the fire or reduce the fire. When a fire occurs inside the cabinet and the cabinet control body 9 is powered off, the drive motor 22 cannot be started. At this time, the first elastic member 27 can drive the worm 25 to actively reverse and ensure that the sealing strip 28 is tightly fitted with the heat dissipation hole 5. At the same time, the coil 36 is powered off and the iron core 35 loses its magnetism. At this time, the second elastic member 33 drives the third connector 32 to rotate and makes one end of it abut against the first connector 30. At this time, the first connector 30 is connected to the second connector 31, and the battery 11 can drive the air pump 14 to start.

[0027] like Figures 1 to 5 As shown, a plurality of cooling fans 17 electrically connected to the electric cabinet control body 9 are fixedly connected inside the outer shell 1, a filter screen 18 is fixedly connected to the outside of the heat dissipation hole 5, and a plurality of limit members 19 are fixedly connected around the filter screen 18. The end of the limit member 19 is set to a conical structure and is made of a flexible and high-temperature resistant material. A positioning hole 20 corresponding to the limit member 19 is opened through the outer shell 1, and the diameter of the positioning hole 20 is smaller than the maximum diameter of the limit member 19. A protective ring 37 is sleeved inside the inlet 15 and the outlet 16. The protective ring 37 and the external wiring are interference fit. There are at least two inlets 15 and outlets 16. The inlet 15 and outlet 16 that are not used during actual wiring need to be sealed with a blind rubber ring. The protective ring 37 and the blind rubber ring are both made of flame-retardant and high-temperature resistant materials.

[0028] It should be noted that the outer shell 1 can be sealed by closing the cabinet door 4 and the sealing plate 6. In addition, the protective ring 37 seals the wire inlet 15 and the wire outlet 16 with the external wires respectively. This not only protects the internal components of the cabinet from dust, but also isolates the internal components from the external environment in the event of a fire, thereby preventing the fire from spreading further. The filter 18 can play a dust-proof role. At the same time, when the sealing strip 28 is tightly fitted with the heat dissipation hole 5, the dust-proof effect can be further improved.

[0029] Embodiment 2 On the basis of the above embodiments, when the electrical control switch cabinet of the charging pile is running at high power, if the heat is not discharged in time, a short circuit and fire may easily occur. However, the existing charging piles do not have a mechanism for active and rapid fire extinguishing, and the safety factor is not high enough.

[0030] like Figure 4 and Fig. 9As shown, the fire extinguishing components include a sleeve 38 fixedly connected to the top of the bottom cover 3, a piston 39 is arranged inside the sleeve 38, a fuse 40 is fixedly connected to one side of the piston 39, the fuse 40 is electrically connected to the battery 11 through the power-off self-starting component, a needle 41 is fixedly connected to the other side of the piston 39, the needle 41 is arranged in a cone, and a third elastic member 42 is connected between one side of the piston 39 and the inner wall of the sleeve 38, a sealing sheet 43 is fixedly connected to one end of the sleeve 38, and an inert gas is filled between the sealing sheet 43 and the piston 39, and the fuse 40 is connected in series between the first connector 30 or the second connector 31 and the battery 11. In actual use, the opening of the sleeve 38 faces upward and the third elastic member 42 is in a compressed state.

[0031] In this embodiment, when a fire occurs inside the cabinet and the electrical cabinet control body 9 is powered off, the battery 11 is energized and the fuse 40 is broken by heat. At this time, the elastic potential energy stored in the third elastic member 42 is released and pushes the piston 39, and the inert gas is compressed. At the same time, the piston 39 continues to move forward and uses the needle 41 to pierce the sealing sheet 43, thereby spraying the inert gas toward the electrical cabinet control body 9. The inert gas has the characteristics of stable chemical properties, non-combustibility, non-combustibility, non-toxicity, and non-corrosiveness, and can play an auxiliary fire extinguishing effect. Compared with the traditional method of using a fire extinguisher to extinguish fire, the fire extinguishing method of this switch cabinet is more timely and will not cause damage to internal components. It has a high safety factor and can ensure the reuse of the switch cabinet, thereby achieving the purpose of cost saving.

[0032] Based on the above embodiments, the present invention also provides an application of the condenser as described above in a refrigerator, so as to further optimize the refrigeration effect of the refrigerator. Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
