Description

Laser type water level gauge with self-adaptive overturn-preventing floater

Technical Field

The utility model relates to the technical field of water leakage and drainage, in particular to a laser type water level gauge with a self-adaptive overturn-preventing floater.

Background

The laser type water level gauge mainly comprises a floater, a reflecting plate, a laser range finder and related accessories, wherein the reflecting plate is placed on the floater and floats on the water surface; the laser range finder is mounted in a fixed position. The laser range finder measures the distance between the reflector and the reflector, and then the current water level value can be calculated. At present, a floater for placing a reflector is cylindrical, and in order to prevent the floater from overturning, guide steel wire ropes need to be arranged on the left side and the right side of the floater, and the guide steel wire ropes penetrate through corresponding limiting holes in the floater to enable the floater to float up and down along the guide steel wire ropes without overturning. In the mode, in the process that the floater fluctuates up and down along with the water level, the guide steel wire rope and the limiting hole in the floater rub against each other, so that the steel wire rope is easily broken or the limiting hole is easily broken, the floater overturns, and the measured value of the laser water level meter is inaccurate or invalid; meanwhile, when the floater is placed into water, 2 lifting ropes are needed, the lifting ropes must be kept to be synchronously and slowly transferred, the floater is prevented from inclining and overturning after entering the water, and the operation difficulty is high, and time and labor are wasted.

Detailed Description

The utility model is described in further detail below with reference to the figures and specific embodiments.

As shown in fig. 1 to 3, a laser type water level gauge with a self-adaptive overturn-preventing floater comprises a laser range finder 1, a reflector 2 is arranged below the laser range finder 1, the reflector 2 is arranged on the upper surface of a buoy 3 with a truncated cone-shaped cavity structure, and a gravity center ball 4 is fixedly arranged on the bottom side inside the buoy 3.

Furthermore, a lifting lug 6 matched with the lifting rope 5 is arranged on one side of the floating barrel 3. In this embodiment, the lifting lug 6 is welded directly to the top side of the pontoon 3.

Furthermore, the tail end of the lifting rope 5 is provided with a lifting hook 7 matched with the lifting lug 6. Like this through hook lifting eye 6 with lifting hook 7 of lifting rope 5, alright with transferring the surface of water with flotation pontoon 3, continue to transfer lifting rope 5, can be so that lifting hook 7 and 6 separation of lifting eye.

Further, the reflector 2 is a circular plate-shaped structure, and the buoy 3 is a circular truncated cone-shaped cavity structure with a wide upper part and a narrow lower part.

Further, the outer circumference of the top of the buoy 3 is also fixedly provided with a mounting ring 8, and the mounting ring 8 is evenly hinged with a plurality of rollers 9. Because the phenomenon that the buoy 3 collides with the well wall possibly exists when the water surface in the measuring well floats up and down, in order to reduce the friction force of the up-and-down floating of the buoy, the buoy is contacted with the well wall through a plurality of rollers 9, so that the friction force of the buoy 3 and the well wall is greatly reduced.

Further, the laser range finder 1 is fixed on a cross beam 10, and a fixed pulley 11 for winding the lifting rope 5 is arranged on the cross beam 10. In this embodiment, fixed pulley 11 can play spacing effect to the process of transferring of lifting rope 5, prevents that lifting rope 5 from taking place the phenomenon of left and right rocking.

The working principle of the embodiment is as follows:

as shown in fig. 2, the lifting hook 7 of the lifting rope 5 hooks the lifting lug 6, so that the buoy 3 can be lowered to the water surface through the lifting rope 5, and the lifting rope 5 is continuously lowered, so that the lifting hook 7 can be separated from the lifting lug 6; after the floating barrel 3 enters water, the water generates upward buoyancy on the floating barrel 3, the integral gravity of the floating barrel 3 is overcome, and a balance state is achieved; when the water surface fluctuates, the buoy 3 deflects, so that the local buoyancy of the buoy 3 is changed, the change of the local buoyancy can inhibit the deflection of the buoy 3, the buoy is prevented from overturning, and the posture of the buoy is restored to be horizontal. For example, if the pontoon 3 deflects to the right, the horizontal projection area on the left side of the pontoon 3 becomes smaller, and the buoyancy becomes smaller; the horizontal projection area of the right side of the buoy 3 is enlarged, the buoyancy difference drives the buoy 3 to deflect to the left side, further deflection of the buoy 3 to the right side is inhibited, and overturning is avoided; if the buoy 3 deflects leftwards, the buoyancy changes reversely, the buoy 3 can be restrained from further deflecting leftwards, the overturning is avoided, the new balance is finally achieved, and the horizontal state of the buoy 3 is kept; in addition, in the embodiment, because the gravity center ball 4 at the bottom in the float bowl 3 has large mass, the gravity center of the float bowl 3 is close to the bottom, as shown in fig. 2, the float bowl 3 enters water in a posture inclined towards the left side, and under the action of buoyancy, the float bowl 3 finally recovers to be horizontal, and the water entering operation is completed.

The above-described embodiments are merely preferred embodiments of the present invention, and should not be construed as limiting the present invention, and features in the embodiments and examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims.
