DETAILED DESCRIPTION

[0016] 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.

[0017] Example 1

[0018] like Figures 1 to 3As shown, an outdoor switch cabinet in the embodiment of the first aspect of the utility model comprises a switch cabinet body 1, a cabinet door 2 is rotatably installed on the front of the switch cabinet body 1, a top cover 3 is fixedly installed on the top surface of the switch cabinet body 1, a heat dissipation groove 4 is opened on the side of the switch cabinet body 1, an automatic blocking device 5 is movably installed inside the heat dissipation groove 4, a mounting ring 6 is fixedly installed on the inner wall of the switch cabinet body 1, the automatic blocking device 5 comprises a connecting seat 51, and electric telescopic rods 52 are fixedly installed on the left and right ends of the connecting seat 51, the number of the connecting seats 51 is two, and the two connecting seats 51 are respectively fixedly installed inside the two mounting rings 6, and the electric telescopic rod 52 A limit block 53 is fixedly installed on the outer end, and a blocking strip 54 is fixedly installed on the outer side of the limit block 53. The number of the blocking strips 54 is two groups, and the sizes of the two groups of blocking strips 54 are adapted to the size of the heat dissipation slot 4. A wire tube 55 is fixedly installed on the middle section of the two connecting seats 51, and one end of the wire tube 55 is fixedly connected to a controller 56, and one end of the controller 56 is electrically connected to a humidity sensor 1 57 and a humidity sensor 2 58 respectively. The wire tube 55 is provided with a wire, and the electric telescopic rod 52 is electrically connected to the controller 56 through the wire, and the humidity sensor 1 57 and the humidity sensor 2 58 are respectively arranged at the bottom and the middle of the heat dissipation slot 4.

[0019] In the above embodiment, it should be noted that humidity sensor 1 57 and humidity sensor 2 58 are respectively arranged in the middle and bottom of the heat dissipation groove 4 to realize accurate measurement of different water levels, thereby realizing graded control, and the limit block 53 is slidably installed in the inner wall of the switch cabinet body 1. Its purpose is to have the function of limiting and prevent the jamming strip 54 from exerting excessive pressure on the electric telescopic rod 52, thereby extending the service life of the device.

[0020] The technical effect achieved by the above embodiment is: by using the size matching of the plug strip 54 and the heat dissipation slot 4, when it is inserted, it has the function of closing the heat dissipation slot 4 to prevent water from entering the inside, and two groups of plug strips 54 can be used to close the upper and lower parts in turn, thereby ensuring the normal operation of the hierarchical control closing of the device and improving its applicability in multiple environments.

[0021] Working principle: When the external precipitation is too large, the humidity sensor 57 at the bottom receives a signal, and then sends a signal to the controller 56, so that it controls the electric telescopic rod 52 at the corresponding position at the bottom to extend, driving the plug strip 54 to plug the heat dissipation slot 4 at the bottom, and then closes its channel to block the entirety. The heat dissipation slot 4 at the upper end is still in a flow state to continue heat dissipation. When the liquid level continues to rise to the humidity sensor 58, it receives a signal, and then controls the electric telescopic rod 52 at the upper end through the wire tube 55 to drive the limit block 53 to extend, so that the plug strip 54 at the corresponding position enters the interior of the heat dissipation slot 4 to complete the blockage.
