The utility model can timely discharge the accumulated water inside the distribution cabinet, and at the same time can prevent the accumulated water outside from infiltrating into the cabinet body.

[0004] With regard to the above-mentioned related technologies, the sealing gasket is made of floating blocks. The accumulated water can lift the sealing gasket upward so that the sealing gasket fits the inner wall of the through hole. However, in actual use, there is a gap between the cabinet body and the cabinet door, which causes the accumulated water to still enter the cabinet body, causing the components inside the distribution cabinet to be in a low humidity environment, affecting the safe use of the distribution cabinet.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-3 A dustproof and explosion-proof reactive power compensation distribution cabinet comprises a distribution cabinet 1 and a cabinet door groove 11 opened at the front end of the distribution cabinet 1, a cabinet door 12 is installed on the front end surface of the distribution cabinet 1, a door side frame 13 is installed on one side of the cabinet door 12, a sealing component 14 is installed inside the distribution cabinet 1 and on one side close to the cabinet door groove 11, and a heat dissipation component 15 is installed at the bottom end of the inside of the distribution cabinet 1 and at the rear end of the sealing component 14.

[0024] The sealing component 14 includes an internal frame 141 and a front slot 142 opened on the front end surface of the internal frame 141. A push frame 146 is slidably installed inside the main body of the internal frame 141. A rubber frame 147 is installed at the front end of the push frame 146. When the humidity is high, the rubber frame 147 is inserted between the cabinet door slot 11 and the door side frame 13 to block the gap and prevent water from entering the interior of the distribution cabinet 1.

[0025] The heat dissipation component 15 includes a bottom box 151 and an exhaust pump 152 installed inside the bottom box 151, an exhaust pipe 153 is installed at the top of the bottom box 151, a dustproof net A154 is installed at the top of the exhaust pipe 153, a humidity sensor 1512 is installed at the top of the bottom box 151, an inner compartment box 1511 is installed at the top of the bottom box 151, a single-chip computer 1513 is installed inside the inner compartment box 1511, the single-chip computer 1513, the humidity sensor 1512 and the exhaust pump 152 are electrically connected, and the humidity sensor 1512 is used to monitor the humidity inside the distribution cabinet 1 in real time.

[0026] An air intake pipe 143 is installed at the rear end of the built-in frame 141, and one end of the air intake pipe 143 is installed in the interior of the bottom box 151. An air bag 145 is installed inside the main body of the built-in frame 141 and at the rear end of the push frame 146, and one end of the air intake pipe 143 is installed at the rear end of the air bag 145. The air inside the bottom box 151 flows into the interior of the air bag 145 through the air intake pipe 143. The inflated air bag 145 will push the push frame 146 to move to one side of the front slot 142, and the rubber frame 147 can be inserted between the cabinet door slot 11 and the door side frame 13.

[0027] A tension spring 144 is installed between the inner wall of the built-in frame 141 and one side of the push frame 146, and the tension spring 144 is arranged on the outside of the airbag 145. When the airbag 145 is deflated, the pulling force of the tension spring 144 is used to pull the push frame 146 to move to one side of the airbag 145, and the rubber frame 147 is pulled out from between the cabinet door groove 11 and the door side frame 13.

[0028] In this embodiment: when the distribution cabinet 1 is in operation, the hot air generated by the operation of the parts inside the distribution cabinet 1 is discharged to the upper part of the distribution cabinet 1. When the cabinet door 12 of the distribution cabinet 1 is closed, the accumulated water flows into the distribution cabinet 1 from the gap between the cabinet door groove 11 and the door side frame 13, and the humidity inside the distribution cabinet 1 increases. The humidity sensor 1512 detects the humidity inside the distribution cabinet 1, and the vacuum pump 152 operates to extract the hot air inside the distribution cabinet 1 through the vacuum pipe 153. The dustproof net A154 is set to remove dust in the air. To block the air, the air flows inside the bottom box 151, and the inside of the airbag 145 is inflated through the air inlet pipe 143. After the airbag 145 is expanded as a whole, it pushes the push frame 146 to move to the side of the front slot 142. The tension spring 144 is pushed by the push frame 146 when it moves. The rubber frame 147 moves from the inside of the front slot 142 into the space between the cabinet door slot 11 and the door side frame 13. The gap is blocked by the rubber frame 147 to prevent accumulated water from flowing into the inside of the distribution cabinet 1 from the gap.

[0029] Example 2: Please refer to Figure 4An exhaust pipe 155 is installed at the rear end of the bottom box 151, and a dustproof net B156 is installed at the top end of the exhaust pipe 155. The dustproof net B156 is located at the lower end of the components inside the distribution cabinet 1.

[0030] Aluminum alloy bars 157 are installed transversely inside the bottom box 151, and multiple groups of aluminum alloy bars 157 are provided. The multiple groups of aluminum alloy bars 157 are installed in the bottom box 151 in an offset manner. The staggered aluminum alloy bars 157 absorb heat and cool the hot air.

[0031] In this embodiment: after the vacuum pump 152 extracts the hot air, the hot air flows inside the bottom box 151. When the hot air passes through the aluminum alloy bar 157, the heat is absorbed by the aluminum alloy bar 157. After the air is cooled, it flows to the bottom end of the distribution cabinet 1 through the exhaust pipe 155. Since the dustproof net B156 is located at the lower end of the internal parts of the distribution cabinet 1, the cooled air can be discharged to the components inside the distribution cabinet 1 through the dustproof net B156 to cool the running components.

[0032] Working principle: The humidity sensor 1512 detects the humidity inside the distribution cabinet 1, and the air extracted by the vacuum pump 152 inflates the interior of the airbag 145 through the air inlet pipe 143. After the airbag 145 is expanded as a whole, it pushes the push frame 146 to move to the side of the front slot 142, and uses the rubber frame 147 to block the gap to prevent accumulated water from flowing into the interior of the distribution cabinet 1 through the gap.
