Description

Technical Field

[0001] The utility model mainly relates to the technical field of slope pressure regulating well water level monitoring, in particular to a slope type pressure regulating well water level meter casting device. Background Art

[0002] A surge well, also known as a pressure well, is a mechanical device used to regulate water pressure in hydropower stations and other places. Since the water supply pipeline of a power station is long, when the unit suddenly drops load and closes the guide vane during operation, there is a large water hammer effect due to the inertia of the water flow, which can easily damage the power generation equipment. If there is no surge well, the water hammer will destroy the guide vanes and other flow-through components. The function of a surge well is to allow the water hammer to have a release channel to reduce the pressure of the flow-through components.

[0003] If the water level in the surge tank is to be monitored online in real time, the water level gauge and transmission cable must be lowered into the bottom of the surge tank and fixed. In existing surge tanks, the water level gauge is generally submerged below the liquid surface at the bottom of the surge tank, and the sloped surge tank is generally sloped downward from the entrance to the bottom. Therefore, the water level gauge cannot be directly lowered and removed by gravity, which makes it inconvenient to maintain and replace the water level gauge at a later stage. Utility Model Content

Specifically, the present invention mainly provides a sloped pressure regulating well water level gauge launching device, which is used to solve the technical problem raised in the above background technology that in a sloped pressure regulating well, the water level gauge cannot be directly dropped to the bottom of the well by gravity.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A sloped pressure regulating well water level meter deployment device comprises a deployment component, wherein the deployment component comprises a U-shaped semicircular elbow and two connecting pipes, wherein the two connecting pipes are respectively located at both ends of the U-shaped semicircular elbow, a traction rope and a sensor cable are arranged in a cavity formed by the U-shaped semicircular elbow and the connecting pipes, a water level sensor is arranged at the lower end of the sensor cable, and three fixed pulleys are arranged at equal intervals in the U-shaped semicircular elbow, and the traction rope passes around the three fixed pulleys.

[0007] Furthermore, an annular limiting member for limiting the movement range of the water level sensor is arranged in the U-shaped semicircular elbow.

[0008] Furthermore, a plurality of connecting clasps are linearly arranged at equal intervals between the sensor cable and the traction rope.

[0009] Furthermore, winches are provided at both ends of the traction rope.

[0010] Furthermore, each of the connecting pipes is linearly provided with a plurality of water-permeable holes at equal intervals.

[0011] Furthermore, each of the connecting pipes is threadedly connected to the U-shaped semicircular elbow, and a plurality of steel clamps are linearly arranged at equal intervals between the two connecting pipes.

[0021] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] Please refer to the attached Figure 1-4 A slope-type pressure regulating well water level meter deployment device includes a deployment component 1, the deployment component 1 includes a U-shaped semicircular elbow 11 and two connecting pipes 12, the two connecting pipes 12 are respectively located at both ends of the U-shaped semicircular elbow 11, a traction rope 13 and a sensor cable 14 are arranged in the cavity formed by the U-shaped semicircular elbow 11 and the connecting pipe 12, a water level sensor 15 is arranged at the lower end of the sensor cable 14, three fixed pulleys 16 are evenly spaced around the U-shaped semicircular elbow 11, and the traction rope 13 passes around the three fixed pulleys 16.

[0024] The above structure realizes that in the sloped pressure regulating well, the water level sensor 15 and the corresponding cable can be directly dropped into the bottom of the well through the throwing component 1, and will not stagnate on the slope in the well. This is very convenient and fast, which is conducive to the online real-time monitoring of the water level of the sloped pressure regulating well, and it is easy to directly pull out the water level sensor 15, which is convenient for the later maintenance and replacement of the water level sensor 15. There is no need to inspect and maintain the water level sensor 15 after the water is stopped, which has certain practical value.

[0025] The specific operation is as follows: first, pass the traction rope 13 through the three fixed pulleys 16 in the U-shaped semicircular elbow 11, and then install the sensor cable 14 on the traction rope 13 through the connecting clamp 18, and then put the structure composed of the U-shaped semicircular elbow 11 and the two connecting pipes 12 into the sloped pressure regulating well, and then rotate a winch 2, and then the traction rope 13 drives the water level sensor 15 to the bottom of the well for real-time detection. When inspection and maintenance are required, another winch 2 can be rotated to pull out the water level sensor 15 through the traction rope 13.

[0026] Please refer to the attached Figure 1 and attached Figure 2A winch 2 is provided at both ends of the traction rope 13. The winch 2 is used to provide a fulcrum point, which is convenient for pulling the traction rope 13. A plurality of water-permeable holes 121 are evenly spaced and linearly arranged on each of the connecting pipes 12. Through the water-permeable holes 121, water in the well can flow into the connecting pipe 12, which is convenient for detection by the water level sensor 15. Each of the connecting pipes 12 is threadedly connected to the U-shaped semicircular elbow 11, and a plurality of steel hoops 19 are evenly spaced and linearly arranged between the two connecting pipes 12. The plurality of steel hoops 19 are used to reinforce the connection between the two connecting pipes 12, so that the overall structure forms a ladder shape.

[0027] Please refer to the attached Figure 3 The U-shaped semicircular elbow 11 is provided with an annular limiter 17 for limiting the movement range of the water level sensor 15. The annular limiter 17 is used to limit the movement range of the water level sensor 15 to prevent the water level sensor 15 from slipping into another connecting pipe 12. A plurality of connecting clasps 18 are linearly arranged at equal intervals between the sensor cable 14 and the traction rope 13. The connecting clasps 18 are used to install the sensor cable 14 on the traction rope 13, so that when the traction rope 13 is pulled, the water level sensor 15 on the sensor cable 14 moves accordingly.
