Embodiment
In order to solve the venthole of existing switch board into water problems, the utility model proposes a kind of waterproof switch board, control
Cabinet cabinet processed is equipped with venthole, and venthole periphery is equipped with sink, is provided with piston movable up and down in the sink, according to weight
Power and law of buoyancy, under normal circumstances, piston is separated with venthole, ensures ventilation function, living when the water level in sink rises
Plug is closed with venthole, reaches waterproof purpose, it is ensured that venthole is not intake, so as to protect switch board cabinet not to be damaged, is realized
Simply, cost is relatively low, and is also prevented from venthole import and is blocked by scum silica frost, and device performance is reliable..
The utility model is described in detail with reference to specification drawings and specific embodiments.
The utility model embodiment provides a kind of waterproof switch board, as shown in Figure 1, including：For integrated electronic member device
The switch board cabinet 1 of part, switch board cabinet 1 are equipped with venthole 2, and 2 periphery of venthole is equipped with sink, and sets in the sink
There is piston 3 movable up and down, and closure or the separation of venthole 2 and piston 3 are controlled by the height of water level in sink.
Venthole 2 is in syphon shape, can ensure that the upper surface of venthole 2 blocks the water droplet of whereabouts and enters switch board cabinet 1
The empty interlayer on top, avoids water droplet from entering in venthole 2, causes switch board cabinet 1 to damage.
Venthole 2 includes：Air inlet 20,21 and the bent portion 22 being arranged between air inlet 20 and gas outlet 21, into
Gas port 20 and gas outlet 21 are arranged in parallel, and guide rod 4 is fixedly installed between the top surface of air inlet 20 and switch board cabinet 1,
Piston 3 is slided along guide rod 4.The sink width of 20 side of air inlet is more than the sink width of the opposite side of air inlet 20.
Piston 3 includes：Closed with venthole 2 or separated first floating block 30, and be arranged on 30 bottom of the first floating block
Second floating block 31, the first floating block 30 and the second floating block 31 are connected by connecting rod 5, and are provided through being oriented in connecting rod 5
The hole of bar 4.
The top of first floating block 30 and air inlet 20 match, air inlet 20 include straight sections 201 and with 201 phase of straight sections
The cylindrical portion 202 of connection, the top of 202 and first floating block 30 of cylindrical portion is in round table-like, so that the top of the first floating block 30
