Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground engineering construction technology, and in particular to a self-opening precipitation depth reading device. Background Technology
[0002] Dewatering is widely used on construction sites to lower the groundwater level, facilitating underground engineering construction. However, traditional dewatering methods often involve setting up water level observation wells (3) and connecting a water pump to a main pipe (1), which in turn connects to a dewatering pipe (2) for continuous dewatering. During this process, water levels are manually monitored using measuring ropes (e.g.,...). Figure 1 As shown, this method is labor-intensive and time-consuming, and the observation results have large errors and cannot provide real-time feedback on water level depth; or it uses complex technical principles such as ultrasound, which is costly to apply, requires a high level of technical expertise from operators, and the equipment is bulky and has a narrow range of applications. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a self-opening precipitation depth reading device that can intuitively read the water level depth and control the start and stop of the precipitation pump by the change of water level height, thus realizing the function of self-opening precipitation control while observing the water level.
[0004] To achieve the above technical effects, this utility model provides a self-opening precipitation depth reading device, installed in a water level observation well within the foundation pit retaining wall. The self-opening precipitation depth reading device includes:
[0005] A float is vertically inserted into the water level observation well and is used to move up and down according to changes in water level. The float has scale lines along its length.
[0006] A dewatering pump is located outside the wellhead of the water level observation well;
[0007] The power circuit has its first end electrically connected to the rainwater pump and its second end electrically connected to the scale line on the float corresponding to the rainfall requirement.
[0008] Preferably, the float is made of hollow plastic.
[0009] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:
[0010] 1) Utilizing the principle of buoyancy, the initial water level depth is manually measured using a hollow plastic float. Water level markings are then made on the float, and upper and lower scale lines are drawn based on these markings. The current water level depth can be read directly from the scale lines on the float.
[0011] 2) Through the water level observation well + float, dewatering pump and power circuit, the change of water level causes the float to move up and down, and the water level depth is read through the scale line on the float. During the up and down movement of the float, the power circuit of the dewatering pump is connected or disconnected, thereby controlling the start and stop of the dewatering pump, and thus starting or stopping the dewatering.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 As shown, this utility model embodiment provides a self-opening precipitation depth reading device, including a water level observation well 3 installed within the foundation pit retaining wall 7. The self-opening precipitation depth reading device includes a float 4, a precipitation pump 5, and an electrical circuit 6. The float 4 is vertically inserted into the water level observation well 3 and moves up and down according to changes in the water level. The float 4 has a scale line 41 along its length. The precipitation pump 5 is located outside the wellhead of the water level observation well 3. The first end of the electrical circuit 6 is electrically connected to the precipitation pump 3, and the second end is electrically connected to the scale line 41 on the float 4 corresponding to the precipitation requirement.
[0019] Furthermore, in this embodiment, the float 4 is made of hollow plastic. Utilizing the principle of buoyancy, and with the mass of the float 4 remaining constant, the projected displacement from the observation port to the float 4 changes proportionally with the water level. This allows for marking water level scales. Specifically, the hollow plastic float 4 is inserted into the water level observation well 3, and the initial water level depth is manually measured. Water level scales are marked on the float 4, and upper and lower scale lines 41 are drawn based on these scales. At this point, the current water level depth can be directly read through the scale lines on the float 4.
[0020] Furthermore, when the water level rises, the float 4 rises until it reaches the mark required for precipitation. At this time, the power circuit 6 is energized, and the precipitation pump 5 starts to precipitate water. When the water level drops, the float 4 falls, the power circuit 6 is de-energized, and the precipitation pump 5 stops precipitating water. This achieves two functions: water level observation and automatic precipitation control.
[0021] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
