[0002] The purpose of a precipitation well is to lower the groundwater level or drain groundwater. It can be deep or shallow. When draining water, the precipitation well uses a precipitation well pipe. A submersible pump is installed in the precipitation well, and the precipitation well pipe is connected to the submersible pump to pump and drain groundwater. During the on-site construction process, the groundwater level of the precipitation well needs to be observed to determine whether the foundation pit can be excavated.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-5 As shown, the utility model provides a technical solution: a water level observation device for a construction precipitation well, comprising an auxiliary plate 1, and a pumping mechanism 3 and an observation mechanism 2 are respectively arranged on the left and right sides of the auxiliary plate 1;

[0030] The observation mechanism 2 includes a circular groove 21 provided on the outer wall of the right side of the auxiliary plate 1 and a rotating shaft 23 connected to the inner wall of the circular groove 21 by a bearing. A coil spring 22 and a measuring rope 24 are respectively wound around the outer wall of the rotating shaft 23. The coil spring 22 is located in the inner cavity of the circular groove 21, and one end of the coil spring 22 is fixedly connected to the inner wall of the circular groove 21, and the other end is fixedly connected to the outer wall of the rotating shaft 23. The rotating shaft 23 is rotated by the elastic force of the coil spring 22, so that the measuring rope 24 is wound around the rotating shaft 23 to avoid the measuring rope from being wound around the rotating shaft 23. The looseness of 24 leads to inaccurate water level measurement. The rotating shaft 23 is fixedly connected to a circular plate 6 at one end away from the auxiliary plate 1. By setting the circular plate 6, the measuring rope 24 on the rotating shaft 23 can be blocked to prevent the measuring rope 24 from falling off the rotating shaft 23. A U-shaped block 25 is fixedly connected to the right side of the auxiliary plate 1. A strip long hole 26 is opened on the right side of the U-shaped block 25. One end of the measuring rope 24 passes through the port on the top of the U-shaped block 25, the strip long hole 26 opened on the right side of the U-shaped block 25, and the measuring rope 24 passes through the port on the top of the U-shaped block 25 and the strip long hole 26 opened on the right side of the U-shaped block 25. A counterweight block 27 is fixedly connected, and a floating plate 28 is fixedly connected to the top of the counterweight block 27. A rope rack 4 is fixedly connected to the outer wall of the auxiliary plate 1 between the circular groove 21 and the U-shaped block 25. The measuring rope 24 passes through the rope hole on the rope rack 4, and the diameter of the measuring rope 24 matches the width of the strip long hole 26, so that the measuring rope 24 can easily pass through the strip long hole 26 under the action of the coil spring 22, and the counterweight block 27 cannot pass through the strip long hole 26. A scale pointer 5 is fixedly connected to the back of the rotating shaft 23 on the right side of the auxiliary plate 1. The scale pointer 5 is convenient to provide a standard observation direction for workers, so that the observation device is easy to use. A scale bar is provided on the surface of the measuring rope 24. The scale bar is provided on the surface of the measuring rope, and the order of the scale bar is that the scale of the end of the measuring rope wound around the rotating shaft 23 is small, and the scale of the end connected to the counterweight block 27 is large, so that the depth of the water level can be conveniently known through the scale of the measuring rope 24 pointed by the scale pointer 5.

[0031] The pumping mechanism 3 includes a base 31 and a bracket 34 which are respectively fixedly connected to the outer wall of the auxiliary plate 1. A water pump 32 is fixedly installed on the top of the base 31 by bolts. The output end of the water pump 32 is connected to a water pipe 33, and the water pipe 33 is fixedly installed on the outer wall of the auxiliary plate 1 through the bracket 34. By setting up the pumping mechanism 3, it is convenient to pump out the water in the precipitation well, thereby facilitating construction.

[0032] Working principle: The buoyancy generated by the floating plate 28 in the water drives the counterweight 27 to float on the water surface. At this time, the measuring rope 24 drives the rotating shaft 23 to rotate under the elastic force of the coil spring 22. The measuring rope 24 is wound around the rotating shaft 23. Since the counterweight 27 cannot pass through the strip-shaped long hole 26, the measuring rope 24 between the counterweight 27 and the rotating shaft 23 is stretched straight, avoiding errors in the water level measurement results due to the relaxation of the measuring rope 24. Then, the user can intuitively observe the depth of the water level at the scale indicator, and it is displayed in real time during the pumping process, which is convenient and fast.

[0033] The water in the precipitation well is pumped into the water pump 32 through the water pump 32, and then transmitted through the water pipe 33 to facilitate the pumping out of the water in the precipitation well, thereby facilitating the construction. The water pipe 33 is fixed to the auxiliary plate 1 through the bracket 34, so that the water pipe 33 will not affect other construction during the water pumping process.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
