It can realize long-term automatic measurement of water depth, water temperature and conductivity parameters, and has the characteristics of good stability, small size and easy to carry. The invention of the three-parameter automatic water level meter has greatly facilitated people's monitoring of surface water and groundwater, and has a very wide range of uses in the fields of hydrological monitoring and environmental monitoring.

[0003] The three-parameter automatic water level gauge has integrated pressure, temperature and electrode sensors, and the outer shell is made of 316L stainless steel or titanium alloy that can contact with harsh measuring media, which is relatively expensive. In actual work, the three-parameter automatic water level gauge is usually directly suspended on the well platform with a rope or placed in a simple protection device. These methods can easily cause the water level gauge to be washed away by water or discovered and damaged by people, and it is very easy to be damaged and lost if left for a long time.

[0004] Based on the above problems, designing a concealed and stable underwater water level monitoring device has become an urgent problem that needs to be solved by technicians in the fields of hydrological monitoring and environmental monitoring. Utility Model Content

[0005] The utility model provides a water level monitoring device fixed on the bottom of the water, which can conceal and stably fix a water level meter on the bottom of the water for monitoring, thereby preventing the water level meter from being washed away by water and artificially damaged, and ensuring the stability and long-term performance of the detection.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention solves the above problems through the following technical solutions:

[0008] In the above scheme, the device is divided into a positioning mechanism and a retracting mechanism. The positioning mechanism is deployed and collected by the retracting mechanism, and the water level meter is loaded on the positioning mechanism and fixed to the bottom of the water for stable and long-term monitoring. The water level meter is fixed on the fixed rod, and the underwater camera is fixed under the retracting rod. The retracting rod and the fixed rod are threaded and detachable. After the ground plug is inserted into the bottom of the water for positioning through the retracting rod, the retracting rod is rotated to separate the retracting rod from the fixed rod, and the underwater fixation of the water level meter is completed. When the water level meter is collected, the underwater camera outputs the position information of the fixed rod to the display device in the form of an image. The operator can complete the threaded cooperation of the retracting rod and the fixed rod according to the displayed information, and can remove the positioning mechanism and the water level meter from the bottom of the water. In the scheme, the water level meter is installed in a concealed and stable manner to prevent the water level meter from being washed away by water and human damage.

[0009] Furthermore, the connector adopts a fishing umbrella universal connector, including a left connector, a right connector, a serration, a fixing nut, a screw, a shock-absorbing gasket and a tightening wrench; the left connector and the right connector are connected by the serration, and the screw passes through the left connector, the serration and the right connector, one end of which is engaged with the fixing nut thread, and the other end is sleeved with the shock-absorbing gasket and connected to the tightening wrench.

The positioning mechanism is placed on the bottom of the water by the retractable mechanism, and the water level gauge 4 is installed on the positioning mechanism. The positioning mechanism includes a ground plug 1, a fixing rod 2 and a connector 3. The ground plug 1 is a four-pin ground plug. The fixing rod 2 is longitudinally fixed to the upper part of the ground plug 1. The connector 3 is fixed to the fixing rod 2 to clamp and fix the water level gauge 4.

[0021] As attached Figure 2 As shown, the connector 3 is a universal connector for fishing umbrellas, including a left connector 31, a right connector 32, a sawtooth 33, a fixing nut 34, a screw rod 35, a shock absorbing washer 36 and a tightening wrench 37. The left connector 31 and the right connector 32 are arranged on the left and right sides and connected by the mutually matching sawtooth 33. One end of the screw rod 34 is threadedly matched with the fixing nut 34, and the other end passes through the left connector 31, the sawtooth 33, the right connector 32, the shock absorbing washer 36 in sequence and is connected to the tightening wrench 34.

[0022] When the water level gauge 4 is installed on the fixed rod 2, the left connector 31 and the right connector 32 are respectively sleeved on the fixed rod 2 and the water level gauge 4, the matching angle of the serration 33 is adjusted to determine the relative angle of the left connector 31 and the right connector 32, the tightening wrench 34 is rotated to adjust the matching length of the screw rod 34 and the fixing nut 34, and then the tightening wrench 34 is pulled down to clamp the left connector 31 and the right connector 32 into position, thereby completing the fixation of the water level gauge 4 relative to the fixed rod 2.

[0023] As attached Figure 1 As shown, the retracting mechanism includes a retracting rod 5 and an underwater camera 6 fixed on the rod body.

The top of the fixed rod 2 and the bottom of the retracting rod 5 are provided with internal and external threads that match each other.

[0024] When a water level monitoring device fixed to the bottom of water is used as described in this embodiment and the water level meter is deployed, the water level meter 4 is fixed on the fixed rod 2, and the underwater camera 6 is fixed under the retractable rod 5. The retractable rod 5 is threadedly matched with the fixed rod 3. The placement conditions of the bottom of water are observed through the display device 7 and the deployment position is selected. After the ground plug 1 is inserted into the bottom of water for positioning through the retractable rod 5, the retractable rod 4 is rotated to separate the retractable rod 4 from the fixed rod 2, and the underwater fixation of the water level meter is completed.

[0025] When collecting the water level meter, the position of the underwater fixed rod is known through the display device 7, and the retracting rod 5 is threadedly matched with the fixed rod 2, so that the positioning mechanism and the water level meter 4 can be taken out from the bottom of the water, and the collection of the water level meter 5 is completed. The utility model can be used to simply and conveniently install the water level meter 4 on the bottom of the water for monitoring, and the water level meter is installed in a concealed and stable manner.
