SUMMERY OF THE UTILITY MODEL

In order to solve the problems that in the prior art, in order to ensure that inspection personnel can timely process the heat supply pipeline at the initial stage of dangerous case occurrence and effectively ensure the stable operation of the heat supply pipeline, the inspection of thermal cells is required every day, a large amount of manpower is consumed, the workload is huge, the danger is large, and a plurality of underground cells are located below main traffic main roads and often seriously affect the traffic during the inspection. Need provide a liquid level monitoring device, can replace artifical real-time supervision to take place the height of the back water level of leaking and send the early warning, avoid the workman to go into the pit to measure on the spot and bring potential safety hazard scheduling problem, improve work efficiency when reduce cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a liquid level monitoring device, is in including liquid level pipe subassembly and setting base and seat of honour that liquid level pipe subassembly both ends are used for fixing, its characterized in that, the liquid level pipe subassembly includes: welded welding head, liquid level pipe, bearing weld cover and water joint in proper order to and assembly plastic sealing head, insulation board and circuit board together, plastic sealing head, insulation board and circuit board whole assembly are in the liquid level is intraductal and the encapsulating is sealed, liquid level outside of tubes surface cover is equipped with a magnetic levitation ball, magnetic levitation ball with liquid level pipe contact part is sliding connection.

Furthermore, the circuit board is connected with a wire, the wire passes through the waterproof connector and extends outwards, and the extension section of the wire is connected with a signal collector.

Further, still be provided with rotary mechanism on the bearing weld bushing, rotary mechanism includes the bearing mount pad and with the joint bearing that the bearing mount pad matches.

According to the technical scheme provided by the utility model, the utility model provides a liquid level monitoring device can replace artifical real-time supervision to take place the height of the back water level of leaking and send the early warning, avoids the workman to go into the pit to measure on the spot and brings the potential safety hazard scheduling problem, has improved work efficiency greatly when reduce cost.

Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the liquid level monitoring device includes a liquid level pipe assembly 1, and an upper seat 21 and a base 22 provided at both ends of the liquid level pipe assembly for fixing, the liquid level pipe assembly includes: welded welding head 11, liquid level pipe 12, bearing weld cover 13 and waterproof 14 joints in proper order to and assembly plastic sealing head 15, insulation board 16 and circuit board 17 together, plastic sealing head, insulation board and circuit board whole assembly are in the liquid level pipe is interior and the encapsulating is sealed, liquid level pipe surface cover is equipped with a magnetic levitation ball 3, the magnetic levitation ball with liquid level pipe contact part is sliding connection.

As shown in fig. 1, the circuit board 17 is connected to a wire 18, the wire passes through the waterproof connector and extends outward, and the extending section of the wire is connected to a signal collector.
