Technical Field

[0001] The invention relates to the technical field of switch cabinets, and in particular to a moisture-proof and heat-dissipating high and low voltage switch cabinet. Background Art

[0002] High and low voltage switchgear is a device that connects high voltage or low voltage cables. It is a distribution equipment used for power distribution, control, metering and cable connection in power supply systems.

[0003] When the switch cabinet is working, the operation of its internal electrical equipment will generate a large amount of heat. By setting channels for ventilation and heat dissipation on the cabinet, the heat in the cabinet can be discharged in time. In the prior art, when the high and low voltage switch cabinets are installed in outdoor environments, in order to prevent the electrical components in the cabinet from being damaged by the accumulated water on the ground in rainy weather, most of them directly close the ventilation and heat dissipation channels of the cabinet to prevent the accumulated water from flowing into the cabinet through the channels. Although this method can prevent the electrical components in the cabinet from being corroded by rainwater, it cannot meet the heat dissipation requirements of the switch cabinet, thereby affecting the normal use of the switch cabinet.

[0009] The inner top of the cabinet is slidably provided with two sliding sleeves, and a driving member for controlling the synchronous movement of the two sliding sleeves is installed on the cabinet. The cabinet is provided with a transmission member and a plug-in member. When the two sliding sleeves move synchronously in opposite directions, the transmission member first drives the ceiling to drive the air pipe to lift up. When the ceiling is lifted to the right position, as the sliding sleeve continues to slide, the air pipe is locked in height by the plug-in member.

[0010] A linkage is provided in the cabinet body, and when the air pipe is lifted up along with the ceiling, the sealing plate slides and closes the ventilation slot under the action of the linkage.

[0011] Preferably, the driving member includes a turntable rotatably connected to the top of the cabinet, and a first motor for controlling the rotation of the turntable is installed on the top of the cabinet.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In this application, when the accumulated water covers the liquid level sensor, the controller will control the two sleeves to slide synchronously in the opposite direction through the driving member. During this process, the ceiling will be lifted up under the action of the transmission member, so that the notch groove is exposed outward. By controlling the lifting of the ceiling, the air inlet and outlet of the switch cabinet are increased to meet the heat dissipation treatment of the cabinet in a water-accumulated environment, thereby ensuring the normal use of the switch cabinet in harsh environments.

[0021] 2. In the present application, when the ceiling is lifted into place, as the sleeve continues to slide, the air pipe is maintained at a fixed height under the action of the connector, preventing the ceiling from being affected by wind from the external environment or objects falling, so that the ceiling remains in a stable lifted state, which is conducive to continuous and effective heat dissipation of the cabinet.

[0022] 3. In the present application, during the process of lifting the ceiling, the sealing plate slides and closes the ventilation slot under the action of the linkage, thereby preventing accumulated water from seeping into the cabinet through the ventilation slot without changing the installation position of the cabinet, thereby protecting the electrical components installed inside the cabinet. Moreover, this water accumulation prevention method is not limited by the internal space of the cabinet, which is conducive to the switch cabinet maintaining a normal size while meeting its functions, and is easy to carry.

[0032] 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.

[0033] See also Figure 1-7 The present invention provides a technical solution: a moisture-proof and heat-dissipating high and low voltage switch cabinet, comprising a cabinet 1, a ventilation slot 101 formed in the cabinet 1, a liquid level sensor 29 installed on the cabinet 1, and a controller installed in the cabinet 1 and electrically connected to the liquid level sensor 29; the liquid level sensor 29 is an existing contact photoelectric liquid level sensor, and its contact head is installed outside the cabinet 1, and is used to detect the water level outside the cabinet 1 in a rainy environment. The output end of the liquid level sensor 29 and the controller are existing central control devices, and the output end of the liquid level sensor 29 is electrically connected to the input end of the controller.

[0034] The outer side of the cabinet 1 is slidably provided with a sealing plate 3 that cooperates with the ventilation slot 101 to close, the outer end of the cabinet 1 is fixedly provided with a blocking bar 2 that is slidably connected with the sealing plate 3, the top of the cabinet 1 is vertically slidably provided with a ceiling 11, and the bottom of the ceiling 11 is fixedly provided with two pairs of air pipes 12 that slide through the cabinet 1;

[0035] A notch 1101 connected to the air pipe 12 is formed inside the ceiling 11, and a blower impeller 26 for cooperating with the air circulation in the cabinet 1 is rotatably installed in the notch 1101. A second motor 27 for controlling the rotation of the blower impeller 26 is installed at the outer end of the ceiling 11; the output shaft of the second motor 27 is vertically distributed with the rotation axis of the blower impeller 26, and the two are driven by bevel gears. As the ceiling 11 is lifted, the notch 1101 located at the bottom of the ceiling 11 is connected to the outside world, and the rotation of the blower impeller 26 is controlled by the second motor 27 to accelerate the discharge of high-temperature gas inside the cabinet 1, thereby meeting the heat dissipation effect of the switch cabinet when there is deep water on the ground in rainy weather.

[0036] Two sliding sleeves 19 are provided for sliding movement on the inner top of the cabinet 1. A driving member for controlling the synchronous movement of the two sliding sleeves 19 is installed on the cabinet 1. Transmission members and connectors are provided in the cabinet 1. When the two sliding sleeves 19 move synchronously in the opposite direction, the transmission member first drives the ceiling 11 to drive the air pipe 12 to lift up. When the ceiling 11 is lifted into place, as the sliding sleeve 19 continues to slide, the height of the air pipe 12 is locked by the connector. When the accumulated water covers the liquid level sensor 29, the liquid level sensor 29 will respond to the water level to the controller, and the controller will control the two sliding sleeves 19 to slide synchronously in the opposite direction through the driving member. In this process, the ceiling 1 1 will be lifted up under the action of the transmission member, so that the notch 1101 at the bottom of the ceiling 11 is exposed outward. By controlling the lifting of the ceiling 11, the air inlet and outlet of the switch cabinet are increased to meet the heat dissipation treatment of the cabinet body 1 in a water-logged environment, thereby ensuring the normal use of the switch cabinet in a harsh environment; when the ceiling 11 is lifted up to the right position, as the sliding sleeve 19 continues to slide, the air pipe 12 will be kept at a fixed height position under the action of the connector, preventing the ceiling 11 from being affected by the wind from the external environment or the falling of objects, so that the ceiling 11 can maintain a stable lifting state, which is conducive to continuous and effective heat dissipation of the cabinet body 1.

[0037] A linkage is provided in the cabinet 1. When the air pipe 12 is lifted up along with the ceiling 11, the sealing plate 3 slides and closes the ventilation slot 101 under the action of the linkage. When the ceiling 11 is lifted up, when the ceiling 11 is about to be lifted into place, the sealing plate 3 slides along the baffle 2 and closes the ventilation slot 101 under the action of the linkage, thereby preventing accumulated water from penetrating into the cabinet 1 through the ventilation slot 101, thereby protecting the electrical components installed inside the cabinet 1.

As the protrusion 20 slides out of the spiral section of the slide rail 1401 and slides into the straight section of the slide rail 1401, the ceiling 11 is lifted into place. At this time, the shaft rod 14 remains stationary, and the air pipe 12 and the horizontal frame 13 fixed to the ceiling 11 will remain at the corresponding height position. As the insertion rod 21 slides into the slot 1301, the insertion and fixation of the horizontal frame 13 is realized, so that the ceiling 11 is stably maintained at the lifting height.
