Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model relates to a foundation pit water level detector, which comprises a housing 12 with an inner cavity 13, a water inlet hole 22 arranged at the bottom end of the housing 12, a floating body 15 arranged at the bottom of the inner cavity, a follower 16 driven to rise when the floating body 15 rises, a movable contact 61 arranged on the follower 16, a fixed contact 66 fixedly arranged at the top of the inner cavity 13, and a double-way lead 68, wherein the double-way lead 68 is respectively connected with the movable contact 61 and the fixed contact 66 and penetrates out of the housing 12 in a sealing manner. Set up body 15 in fixed mounting's the casing 12, casing 12 below body 15 sets up into water hole 22, and water pours into from water hole 22 when suffering the water logging, thereby makes body 15 come-up drive follower 16 rise, and then moving contact 61 upwards with decide contact 66 contact switch-on, can guarantee that the water level detector is intact when the transmission suffers the feedback signal of water logging, experience the water logging also can not receive the damage, also can repeat effective use.
Furthermore, a sealing partition plate 31 which divides the inner cavity 13 into an upper cavity 32 and a lower cavity 33 is arranged in the shell 12, so that only the lower cavity 33 where the water inlet hole 22 is located can be filled when water is immersed into the water, and the upper cavity 32 is used for placing electronic components and cannot enter the water, thereby ensuring that the water level detector cannot be damaged even if the water is immersed into the water during the use process. The top of the lower cavity 33 allowing water to be poured in can be provided with an air hole, so that air can be exhausted when water enters, air can be supplemented when water is drained, the height of the water level can be reflected in real time, the water level inside the lower cavity is consistent with the water level outside the lower cavity in the corresponding water level interval, and the water level difference between the inside and the outside caused by the existence of the internal air pressure is avoided.
Specifically, the follower 16 is disposed within the upper chamber 32, the follower 16 having a passive magnet 62; the floating body 15 is positioned in the lower cavity 33, and the floating body 15 is provided with a driving magnet 52; the same poles of the driving magnet 52 and the driven magnet 62 are mutually repelled, so that the driven magnet 62 is supported and lifted when the driving magnet 52 is lifted. The sealing diaphragm 31 only blocks the flow of water and does not block the penetration of magnetic force, the pushing of the magnetic force makes the driven magnet 62 rise, so that the follower 16 rises to trigger the transmission of the water immersion signal. Even if the barrier of the sealing partition plate 31 is not provided, the follower 16 can be lifted to the height capable of triggering the feedback signal before the electronic components are soaked in water, and the air pressure is arranged in the follower, so that the safety of the electronic components can be ensured without damage when the external water level is ultrahigh.
