Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring, in particular to an underground water level monitoring device. Background Art

[0002] Groundwater resources are more complex than surface water resources. Therefore, the changes in the quality and quantity of groundwater itself, the environmental conditions that cause groundwater changes, and the movement laws of groundwater cannot be directly observed. Groundwater pollution and ground subsidence caused by over-exploitation of groundwater are slow-changing. Once accumulated to a certain extent, it becomes irreversible damage. At the same time, groundwater affects the normal life of human beings. The monitoring of groundwater level is of indispensable significance. At present, groundwater level monitoring is usually carried out by regularly testing the water level of groundwater level observation wells to determine the groundwater level distribution in a certain area. The traditional detection method uses a pressure water level gauge and is detected by manually lowering a rope. While solving the problem of measuring groundwater level, it also has the following disadvantages:

[0003] The overall structure of the existing monitoring device is relatively complex, and when measuring, the water level meter body is prone to collide with the well wall, and the suspension rope is prone to rub against the well wall, thereby affecting the service life of the water level meter and the suspension rope.

[0023] The groundwater level monitoring device of the above structure is used by the user to move the bracket 1 to the position required for monitoring, and then align the monitoring frame 5 with the monitoring position. At this time, the user rotates the wire wheel 2, and the wire end on the wire wheel 2 moves downward due to the weight of the monitoring frame 5. The wire end of the wire wheel 2 guides the monitoring frame 5 vertically downward through the guide wheel 4, and locks the rotation of the wire wheel 2 through the second locking mechanism 200. In conjunction with the sensor 12, the user can know the depth of the downward movement through the control panel 11. When the monitoring frame 5 contacts the groundwater, the water quality is monitored through the detection rod 7. When the floating fat 6 contacts the water, the floating fat 6 moves upward along the monitoring frame 5, and at the same time, the collecting shell 8 scoops up the groundwater and moves it to the bottom of the monitoring frame 5. After moving to a certain position, the floating fat 6 is fixed at the required position through the first locking mechanism 100. Compared with the prior art, the wire end of the wire wheel can avoid collision and can collect groundwater samples at the same time.

[0024] like Figure 5 and 6 As shown, in some embodiments of the utility model, in order to achieve the effect of fixing the floating fat 6 at a desired position, the first locking mechanism 100 includes guide rods 101 symmetrically fixed on the floating fat 6, each of the guide rods 101 is movably plugged above the monitoring frame 5, and a plurality of card slots 102 are symmetrically arranged on each of the guide rods 101, and card blocks 104 are movably hinged on both sides of each of the guide rods 101 and located above the monitoring frame 5, and a hinge shaft 105 is fixed to each of the card blocks 104 at one time, and a plug-in shaft 106 is symmetrically fixed above the monitoring frame 5, and a movable plate 107 is movably plugged on each of the plug-in shafts 106, and an oblique groove 108 is symmetrically fixed on one side of each of the movable plates 107, and each of the oblique grooves 108 is movably sleeved on an adjacent hinge shaft 105, and a spring 109 is directly and fixedly connected between the movable plate 107 and the plug-in shaft 106.

At this time, the block 104 is stuck in the slot 102. When unlocking is required, the user pulls up the moving plate 107. At this time, the oblique groove 108 on the moving plate 107 drives the hinge shaft 105 to move. When the hinge shaft 105 moves, it drives the block 104 to swing outward, so that the block 104 and the slot 102 are separated.

[0027] When the groundwater level monitoring device using the above structure is in operation, the user moves the snap block 205 along the insertion slot 204 toward the snap slot 203, so that the snap block 205 is snapped into the snap slot 203. When unlocking is required, the user pulls the snap block 205 upward so that the snap block 205 is snapped into the snap slot 206 through the snap block 207, so that the snap slot 206, the snap block 207 and the snap slot 203 are separated.
