Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a dual-fan heat dissipation device for a charging pile. Background Art

[0002] With the vigorous development of the electric vehicle industry, charging piles, as important supporting facilities for electric vehicles, are attracting more and more attention for their performance and stability. Charging piles will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will not only affect the working efficiency of the charging piles, but may also cause damage to the internal components of the charging piles. Therefore, a dual-fan heat dissipation device for the charging pile is needed to efficiently dissipate the heat of the charging piles.

[0003] However, during the operation of the existing dual-fan heat dissipation device of the charging pile, it is not convenient to prevent dust from entering the fan when the fan stops running. Dust, debris, etc. can easily enter the heat dissipation device and adhere to the internal parts of the fan, which not only affects the fan speed and heat dissipation effect, but also may cause wear and blockage of the fan blades, shortening the service life of the heat dissipation device. Utility Model Content

[0004] The purpose of the utility model is to provide a dual-fan heat dissipation device for a charging pile. By setting a dust-proof fan mechanism, the problem that the existing dual-fan heat dissipation device for a charging pile is not convenient to prevent dust from entering the fan when the fan stops running during operation is solved, and dust, debris, etc. can easily enter the interior of the heat dissipation device and adhere to the internal parts of the fan, which not only affects the fan speed and heat dissipation effect, but also may cause wear and blockage of the fan blades, thereby shortening the service life of the heat dissipation device.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a dual-fan heat dissipation device for a charging pile, comprising a heat dissipation box, on which a dust-proof fan mechanism and an oscillating cleaning mechanism are provided;

[0007] The dust-proof fan mechanism includes a dust-proof component and a fan component, the dust-proof component includes two rectangular fixing rods fixedly connected to the inner wall of the heat dissipation box, a number of hinged rods 1 are fixedly connected between the two rectangular fixing rods, the outer walls of several hinged rods 1 are rotatably connected with dust-proof plates, the bottoms of several dust-proof plates are rotatably connected with hinged rod 2, and the left and right sides of several hinged rods 2 are rotatably connected with two limit rods, the fan component includes two fixing rods 1 fixedly connected to the inner wall of the heat dissipation box, a rotating shaft is rotatably passed through the two fixing rods 1, impellers are fixedly connected to the outer walls of the two rotating shafts, and a pulley 1 is fixedly connected to the outer wall of the rotating shaft located on the left.

[0008] Furthermore, a second fixing rod is fixedly connected to the left inner wall of the heat dissipation box, a first motor is fixedly connected to the front side of the second fixing rod, and an output shaft of the first motor is fixedly connected to the rotating shaft through a coupling.

[0009] Furthermore, a second pulley is fixedly connected to the outer wall of the rotating shaft located on the right side, and belts are sleeved on the outer walls of the first pulley and the second pulley.

[0010] Furthermore, the oscillating cleaning mechanism includes an oscillating component and a power component. The oscillating component includes a filter plate arranged at the bottom of the heat dissipation box, and the top of the filter plate is fixedly connected to a cylindrical box.

[0011] Furthermore, an oscillation block 1 is slidably connected to the inner wall of the cylindrical box, a spring is fixedly connected to the bottom of the oscillation block 1, the bottom of the spring is fixedly connected to the filter plate, and an oscillation rod is fixedly connected to the bottom of the oscillation block 1.

[0012] Furthermore, the power assembly includes a third fixing rod fixedly connected to the right inner wall of the heat dissipation box, and a sliding rod is slidably penetrated through the third fixing rod.

[0013] Furthermore, the bottom of the sliding rod is fixedly connected to an oscillation block 2, and the top of the sliding rod is hingedly provided with a hinge rod 3.

[0014] Furthermore, a turntable is hingedly provided on the left side of the hinged rod three, a motor two is fixedly connected to the top inner wall of the heat dissipation box, and an output shaft of the motor two is fixedly connected to the turntable through a coupling.

[0015] The utility model has the following beneficial effects:

[0016] The second belt pulley is driven by the belt pulley on the right side, so that the two impellers rotate to generate wind force, thereby blowing the dust shield on the hinged rod one to rotate upward, and the dust shield is blown away by the weight of the hinged rod one. When the wind blows, the dust shield is easily blown away when there is wind, and falls away with gravity when there is no wind. When the hinged rod one is blown up, it will keep synchronization due to the limiting effect of the limiting rod to prevent each other from getting stuck. After the motor one is turned off, all the dust shields fall back with gravity to block in front of the fan assembly, so that dust, debris, etc. can be prevented from entering the fan when the device stops, thereby avoiding wear and blockage of the fan blades, and also protecting the fan assembly from damage by the external environment, thereby ensuring the normal operation of the heat dissipation device when it is started next time.

[0017] 2. By setting an oscillating cleaning mechanism, when motor 1 is started, motor 2 is started, and motor 2 drives the turntable to rotate, and the turntable drives the hinged rod 3 on it to move, and the hinged rod 3 drives the sliding rod below it to move. At this time, due to the limiting effect of the fixed rod 3, the sliding rod will make a vertical reciprocating motion, thereby driving the oscillating block 2 to continuously hit the oscillating block 1. When the oscillating block 1 is hit, it will squeeze the spring to make it contract, so that the oscillating block 1 brings the oscillating rod down and hits the filter plate. After the oscillating block 2 leaves the oscillating block 1, the spring rebounds, and the oscillating block 1 and the oscillating rod reset, waiting for the continuous impact of the oscillating block 2, so that the filter plate is subjected to continuous oscillation, so that the dust and debris on the filter plate are shaken off, realizing the automatic cleaning function, preventing the filter plate from being blocked by dust, thereby maintaining its good filtration efficiency, ensuring that the air entering the fan is unobstructed, and thus ensuring the normal operation of the device.
