[0024] Please refer to Figure 1-4 , the technical solution adopted by this utility model is:

[0025] A waterproof device for a ring network cabinet comprises a cabinet body with ventilation slots on the side walls, a waterproof box is installed on the cabinet body, and the waterproof box cover is provided on the ventilation slots, a first ventilation opening arranged opposite to the ventilation slots is provided on a side of the waterproof box away from the cabinet body, a lifting drive member is installed on the top of the waterproof box, the telescopic end of the lifting drive member passes through the top of the waterproof box and is provided with a lifting plate, and the lifting plate abuts against the opposite side walls of the inner cavity of the waterproof box, a second ventilation opening is provided through the lifting plate, and when the lifting plate abuts against the bottom of the inner cavity of the waterproof box, the second ventilation opening and the first ventilation opening are staggered, a sealing block that cooperates with the lifting plate is provided between the side walls of the inner cavity of the waterproof box, the sealing block is located above the ventilation slots and is provided with a sliding groove that cooperates with the lifting plate.

[0026] From the above description, it can be seen that the beneficial effects of the present invention are:

[0027] In rainy weather, the ring network cabinet of the present invention can drive the lifting plate to descend through the lifting drive member and abut against the bottom of the inner cavity of the waterproof box, so that a staggered heat dissipation channel is formed between the first vent, the second vent and the ventilation groove. When rainwater enters the waterproof box through the first vent, it can be blocked by the lifting plate to prevent rainwater from entering the cabinet, and a heat dissipation channel can still be formed in the waterproof box to ensure that the cabinet still has a certain heat dissipation effect. Under normal use, the cooperation of the first vent and the ventilation groove can ensure the heat dissipation effect of the cabinet in rainy weather.

[0028] Furthermore, there are two lifting plates, the tops of the two lifting plates are connected by a connecting strip, and the second vents on the two lifting plates are staggered.

[0029] From the above description, it can be seen that the two lifting plates can further block rainwater entering the waterproof box, thereby preventing rainwater from entering the cabinet.

[0030] Furthermore, a distance is provided between the two lifting plates.

[0031] It can be seen from the above description that the second vents between the two lifting plates can form a channel for air flow, thereby ensuring air circulation.

[0032] Furthermore, a rubber wiper strip is provided at the bottom of the sealing block and is in contact with the two side surfaces of the lifting plate.

[0033] It can be seen from the above description that rainwater adhering to the surface of the lifting plate can be scraped off to prevent the rainwater from adhering to the lifting plate.

[0034] Furthermore, the lifting drive component is an electric cylinder.

[0035] From the above description, it can be seen that the electric cylinder is easy to disassemble and assemble, and the control principle is simple.

[0036] Furthermore, a filter is installed on a side of the waterproof box away from the cabinet, and the filter cover is arranged on the first vent.

[0037] From the above description, it can be seen that the setting of the filter can filter the air entering the waterproof box to prevent dust from entering the cabinet.

[0038] Furthermore, the lifting plate is a dehumidification and moisture-proof plate.

[0039] From the above description, it can be seen that the use of the dehumidification and moisture-proof board can absorb the wet air in the rainwater entering the waterproof box.

[0040] Furthermore, a drainage outlet is provided at the bottom of the waterproof box.

[0041] From the above description, it can be seen that the provision of the drain outlet can achieve timely drainage of rainwater from the waterproof box.

[0042] Furthermore, an openable baffle assembly is provided at the bottom of the waterproof box, and the baffle assembly blocks the drain outlet. The baffle assembly includes four limit rods installed at the bottom of the waterproof box, and baffles are slidably connected between the four limit rods. The baffle is located below the lifting plate and covers the drain outlet. A limit block is installed at the bottom of the limit rod, and a spring is provided on the outer wall of the limit rod, and the spring is located between the limit block and the baffle. The cross-sectional shape of the baffle is convex, and the protruding end of the baffle is inserted into the drain outlet.

[0043] From the above description, it can be seen that the drain outlet can be blocked by the setting of the baffle assembly, so that in non-rainy weather, the external cold air can directly enter the ventilation slot of the cabinet along the first vent of the waterproof box, that is, the drain outlet will not cause air diversion, thereby ensuring the heat dissipation performance of the ring network cabinet, and when the lifting plate descends, the baffle can be pushed out of the drain outlet by the lifting plate to automatically open the drain outlet, and then when the lifting plate is separated from the baffle, it can return to its original position under the action of the spring restoring force and re-seal the drain outlet.

[0046] Please refer to Figure 3 As shown, there are two lifting plates 5 , the tops of the two lifting plates 5 are connected by a connecting strip, the second vents 6 on the two lifting plates 5 are staggered, and a distance is provided between the two lifting plates 5 .

[0047] Please refer to Figure 4 The bottom of the sealing block 7 is provided with a rubber wiper strip 9 that abuts against the two side surfaces of the lifting plate 5.

[0048] Please refer to Figure 1 , the lifting drive component 4 is an electric cylinder.

[0049] Please refer to Figure 1 and Figure 2 A filter screen 10 is installed on a side of the waterproof box 2 away from the cabinet 1 , and the filter screen 10 covers the first vent 3 .

[0050] Please refer to Figure 2 and Figure 4 A drain outlet 11 is provided at the bottom of the waterproof box 2 .

[0051] Please refer to Figure 4 An openable baffle assembly 12 is provided at the bottom of the waterproof box 2, and the baffle assembly 12 blocks the drain outlet 11. The baffle assembly 12 includes four 121 installed at the bottom of the waterproof box 2, and a baffle 122 is slidably connected between the four 121. The baffle 122 is located below the lifting plate 5 and covers the drain outlet 11. A limit block 123 is installed at the bottom of the 121, and a spring 124 is provided on the outer wall of the 121, and the spring 124 is located between the limit block 123 and the baffle 122.

[0052] Please refer to Figure 4 The cross-sectional shape of the baffle 122 is convex, and the protruding end of the baffle 122 is inserted into the drain outlet 11.

[0053] In this embodiment, no improvement is made to the structure and construction of the cabinet itself, and therefore no improvement is made to the connection lines and structure of the electronic components inside the cabinet.

[0054] The working process of the above waterproof device is as follows:

[0055] When it rains, the lifting drive member 4 is started (the lifting drive member 4 can be manually started by the operator or automatically started by the controller), and the lifting drive member 4 pushes the lifting plate 5 down, so that the bottom of the lifting plate 5 contacts the protrusion of the baffle 122 and pushes the baffle 122 away from the drain outlet 11, so that the drain outlet 11 is opened, and at this time, a staggered air flow channel is formed between the first vent 3, the second vents 6 of the two lifting plates 5 and the ventilation slot, thereby maintaining the heat dissipation effect of the cabinet 1;

[0056] At this time, when rainwater flows into the waterproof box 2 through the first vent 3, it first hits the filter 10, and some of the rainwater enters the waterproof box 2. Then, it is blocked by the two lifting plates 5 in sequence to prevent the rainwater from entering the cabinet 1. The blocked rainwater is discharged through the drain port 11.

[0057] After the rain stops, the lifting drive 4 pulls the lifting plate 5 back and inserts it into the sealing block 7. During the pulling back process, the rubber wiper strip 9 scrapes off the water stains on both sides of the lifting plate 5, and the baffle 122 returns to its original position under the action of the restoring force of the spring 124 to re-block the drain outlet 11.

[0058] To sum up, the utility model provides a waterproof device for a ring network cabinet, which can drive the lifting plate to descend through the lifting drive member and abut against the bottom of the inner cavity of the waterproof box in rainy weather, so that a staggered heat dissipation channel is formed between the first vent, the second vent and the ventilation groove. When rainwater enters the waterproof box through the first vent, it can be blocked by the lifting plate to prevent rainwater from entering the cabinet, and a heat dissipation channel can still be formed in the waterproof box to ensure that the cabinet still has a certain heat dissipation effect. Under normal use, the cooperation of the first vent and the ventilation groove can ensure the heat dissipation effect of the cabinet in rainy weather.
