Embodiment

[0028] In this embodiment, the device for measuring water level by automatic lifting is as follows: Figure 1-Figure 6 As shown, including 1-fixing ring in the middle of the floating ball, 2-scaling rope, 3-steel cable, 4-bottom fixing device, 5-fixing rod, 6-handle, 7-winding wheel, 8-riser, 9 -base, 10-bearing, 11-floating ball.

[0029] When in use, first open a hole with a diameter equal to the fixed ring in the middle of the floating ball on the large-area covering on the upper part of the water body, and then according to Figure 5 Install the upper body on the pre-drilled hole, and place the bottom fixing device 4 at the place where the center of the hole is vertically down. The device is Image 6 In the shown annular device, an expansion bolt is punched at a corresponding position and then vertically welded on the bottom of the channel with its shank, and its diameter is greater than that of the graduated rope. A section of welding steel cable 3 corresponding to the ...

Abstract

The invention provides an automatic lifting measuring device and measuring method for the water level of a top covering channel. The device comprises a floating ball, a steel cable, a scale rope, a bottom fixing device and a winding device, the bottom fixing device is fixedly mounted on a bottom wall of the channel; a hole is formed in the top of the channel in a covering mode, the winding deviceis installed on the hole, a fixing ring is arranged in the middle of the floating ball, the scale rope starts from the bottom of the floating ball, sequentially penetrates through a circular ring of the bottom fixing device and the fixing ring to be connected to the winding device, and the steel cable is fixedly connected with the bottom fixing device and the winding device, and the steel cable penetrates through the fixing ring. The brand-new measuring device and method are provided for measuring the water level in the channel with the covered upper portion, and the measuring device and method have the advantages of being simple in structure, time-saving, labor-saving, convenient to use, efficient and the like.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering and relates to the measurement of the water level of a channel, in particular to an automatic lifting measuring device and a measuring method for the water level of a channel covered by the top. Background technique [0002] Water level is an important parameter in hydraulic engineering. Therefore, the accuracy and accuracy of water level measurement are very important for water conservancy projects. However, in current water conservancy projects, existing water level measuring devices can only be used to measure the water surface without shelter, and it is impossible to measure the water level when there is a large area of ​​permanent coverage on the top of the channel and the water body is surrounded by no light. Examples include large box channels, or other channels with permanent coverings on top, etc. [0003] Designing a water level measuring device with simple struct...
