Description

Technical Field

[0001] This invention relates to the field of observation equipment technology, specifically to a groundwater level observation device that can be placed for a long period of time. Background Technology

[0002] Groundwater level observation is generally carried out by drilling a vertical observation well at a selected observation location and observing using existing equipment, such as the most common steel tape level gauge. When in use, the end of the steel tape level gauge is lowered along the observation well. When the sensor at the end descends to the groundwater level, an alarm is issued, and the operator above will observe it.

[0003] Currently, when long-term groundwater level monitoring is required for an observation well, the following problems often exist:

[0004] 1. As the monitoring and observation time continues to extend, microorganisms, silt and other substances are easily attached to the surface of the water level sensor, which causes inaccurate signal monitoring and reception of the water level sensor and makes the water level sensor and other components frequently damaged and repaired.

[0005] 2. The seepage holes on the seepage cylinder outside the water level sensor are also easily blocked. Therefore, it is necessary to frequently remove it from the well hole for cleaning, which increases the workload of the staff.

[0006] Therefore, those skilled in the art have provided a groundwater level monitoring device that can be placed for a long time to solve the problems mentioned in the background art. Summary of the Invention

[0026] 1. In this invention, by guiding and positioning the water level gauge and setting up a cleaning mechanism, the water level gauge can be placed for long-term monitoring and observation of groundwater level conditions. This avoids the accumulation of microorganisms, silt, and other substances on the surface of the water level gauge as the monitoring and observation time continues to extend, which would cause inaccurate signal reception of the water level sensor and extend the service life of the water level gauge.

[0027] 2. In this invention, the water level gauge is directly controlled via a control console. The structure of the walking wheel frame, dredging mechanism, and cleaning mechanism avoids disassembling the water level gauge from the well hole, thus improving cleaning efficiency.

[0042] Borehole 5;

[0043] The seepage pipe 6 has seepage holes on its wall; and

[0044] The walking and positioning mechanism 10 is capable of moving forward or backward along the inner wall of the seepage pipe 6, and a water level gauge 8 is installed at the lower end of the walking and positioning mechanism 10.

[0045] In this embodiment, the walking positioning mechanism 10 includes a drive mechanism 101, with at least two sets of vertically parallel walking wheel frames 102 on its outer side. A fixing column 103 is fixed at its bottom, and a fixing plate 104 is fixedly connected to the lower end of the fixing column 103. The upper end of the sliding column 105 is fixedly connected to the shaft of the fixing plate 104. A water level gauge 8 is connected and installed at the lower end of the sliding column 105. A rope hole is also provided on the fixing plate 104. A limiting protrusion 1051 is fixed on the outer wall of the sliding column 105. The walking positioning mechanism 10 is also provided with a cleaning mechanism 7 for cleaning the inner wall of the seepage pipe 6 and the surface of the water level gauge 8.

[0046] Specifically, the positioning guide wheel is driven by the drive mechanism to move and position the water level gauge 8 to the required monitoring and observation position. The cleaning mechanism 7 cleans and unblocks the dirt attached to the surface of the water level gauge and the blockage of the seepage hole when the water level gauge and seepage pipe are placed for a long time, so as to ensure the accuracy of monitoring and observation.

[0047] In this embodiment, the cleaning mechanism 7 includes: a cross plate 72, the central part of which is provided with a sliding hole 721 that slides in cooperation with the sliding column 105 and the limiting protrusion 1051; a support rope 73 is connected to the cross end of the cross plate 72 near the axis; the upper end of the support rope 73 passes through the rope hole and is locked by a locking ring 71; the locking ring 71 is connected to the lower end of the main rope 11; the upper end of the main rope 11 is connected to the reel 2; a long rod 751 is fixed to the outer side of the cross end of the cross plate 72; a cleaning plate is installed on the long rod 751; a return spring 74 is sleeved on the outer side of the sliding column 105; its upper and lower ends are connected to the lower end face of the cross plate 72 and the upper end face of the water level gauge 8, respectively; and a dredging mechanism 9, which is set near the bottom of the seepage pipe 6 for dredging the seepage hole;

[0048] Specifically, during cleaning, the main rope 11 is wound up and down by the reel, and the return spring is used to pull the support rope to drive the cross plate to slide up and down, thereby driving the cleaning plate to clean the surface of the water level gauge and the wall of the seepage pipe. It can also be used in conjunction with the drive mechanism to increase the cleaning area of ​​the seepage pipe wall.

[0049] In this embodiment, the cleaning plate includes a short rod 752, which is fixedly attached to the long rod 751. Its inner and outer ends are respectively fixedly connected to a scraper 753 that is close to the surface of the water level gauge and a scraper 754 that is close to the inner wall of the seepage pipe.

[0050] In this embodiment, the first scraper 753 and the second scraper 754 are circular ring structures.

[0051] In this embodiment, the cross-section of scraper blade 1 753 / scraper blade 2 754 is an equilateral triangle.

[0052] In this embodiment, the reel 2 is controlled and driven by the control console 1, and a cover 3 is provided at the upper end of the well hole 5. A positioning guide wheel 4 for positioning and guiding the main rope is installed in the cover 3.

[0054] When the sensing spring 97 detects that the weight supported by the dust collection tray increases by a certain weight M, it can provide feedback to the control console, which can then adjust the drive mechanism to drive the walking wheel frame. This causes the magnetic block to move towards the guide magnetic block, and the guide magnetic block becomes magnetic and attracts the magnetic block. This allows the polygonal frame to move along the square of the seepage hole, thereby clearing the seepage hole from the inside out. After clearing, the polygonal frame is controlled to move towards the dust collection tray, and the top of the clearing wheel is used to push the dust collection tray multiple times to remove the dust accumulated on the surface of the dust collection tray.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
