Description

Technical Field

[0001] The utility model relates to the technical field of sump drainage, in particular to a sump liquid level sensing device. Background Art

[0002] When a construction project is excavating a foundation pit, if the groundwater level is relatively high and the base elevation is below the groundwater level, a drainage method needs to be set up. A sump is a relatively simple method, which is suitable for base burial depths of less than 5m.

[0003] At present, most of the sumps liquid level sensors are of float type or probe type. Among them, the float type sensor has the problem of insensitivity and is easily unable to operate due to garbage attachment. Although the probe type liquid level sensor is sensitive, it is easily disturbed by the fluctuating water surface, causing the drainage pump to start and stop frequently, which can easily cause the drainage pump to overheat and overload. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a sump liquid level sensing device, which allows water in the sump to enter the interior of the pipe body through the water inlet. At this time, the water inside the pipe body is at the same height as the water level in the sump. At the same time, as the water level rises, the water level probe at the lower end is gradually squeezed to move until the induction magnetic block on the upper side of the water level probe at the lower end contacts the magnetic alarm, thereby sounding an alarm. Similarly, the magnetic alarm at the upper end is also sounded.

[0005] The technical solution to achieve the purpose of the utility model is: a sump liquid level sensing device, including a pipe body, the inner side of the pipe body is provided with a plurality of water inlets distributed in a circle at equal intervals at the lower end, and also includes: a sensing mechanism, the sensing mechanism is arranged inside the pipe body; the sensing mechanism includes a plurality of slide rails symmetrically fixed to the inner wall of the pipe body at equal intervals, and two water level probes are arranged on the inner side of the pipe body at equal intervals, and sliders compatible with the plurality of slide rails are symmetrically fixed to the outer sides of the two water level probes, and the plurality of slide rails are respectively slidably connected to the inner sides of the plurality of slide rails, wherein magnetic alarms are fixedly installed on the upper ends of the two slide rails, and induction magnets corresponding to the two magnetic alarms are arranged on the upper sides of the two water level probes.

[0006] In some embodiments, a water pipe is disposed inside the tube body, one end of the water pipe is located at the bottom of the inner side of the tube body, and the other end of the water pipe is connected to an external drainage device.

[0007] In some embodiments, two fixing plates are symmetrically fixed to the outer side of the tube body, and the inner sides of the two fixing plates are both rotatably connected with screws through threads.

[0008] In some embodiments, handles are fixed to the upper ends of the two screws.

[0009] In some embodiments, the plurality of water inlets are specifically trapezoidal in shape.

[0010] In some embodiments, the two handles are specifically regular pentagonal shapes.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First, the utility model allows the water in the sump to enter the pipe body through the water inlet. At this time, the water in the pipe body is at the same level as the water level in the sump. At the same time, as the water level rises, the water level probe at the lower end is gradually squeezed to move until the induction magnetic block on the upper side of the water level probe at the lower end contacts the magnetic alarm and sounds an alarm. Similarly, the magnetic alarm at the upper end sounds an alarm.

[0013] Second, the utility model has two screws rotatably installed on the inner sides of the two fixing plates. When the pipe body is installed and fixed, the two screws can be rotated and embedded in the soil, thereby improving the stability of the pipe body installation;

[0014] The invention solves the problem that the existing float type sensor is not sensitive and the probe type liquid level sensor is easily disturbed by the fluctuating water surface, causing the drainage pump to start and stop frequently. BRIEF DESCRIPTION OF THE DRAWINGS
