The utility model has a simple structure and is easy to use. The water quality sensor can be driven to move up and down by extending and contracting the telescopic rod, thereby adjusting the position of the water quality sensor to monitor the water quality at different depths. At the same time, the water quality sensor can be moved out of the water when not in use, thereby avoiding long-term contact between the water quality sensor and water, reducing the influence of substances in the water on the water quality sensor, and at the same time, in conjunction with a filtering network, it can block objects in the water, further reducing the influence of substances on the water quality sensor, thereby bringing convenience to use.

DETAILED DESCRIPTION

[0015] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0016] like Figure 1-2 As shown, the utility model describes a water quality monitoring device for a water conservancy dam, comprising a base plate 1, an L-shaped plate 2 is installed on the top surface of the base plate 1, two telescopic rods 3 distributed left and right are installed on the top surface of the L-shaped plate 2, a transverse plate 4 is installed between the bottom ends of the two telescopic rods 3, arc plates 5 are installed on both sides of the transverse plate 4, an adjusting rod 6 is threadedly installed on each of the arc plates 5, a clamping plate 7 is rotatably installed at one end of each of the adjusting rods 6, a filter cage 8 is installed between the two clamping plates 7, a placement block 9 is installed on the bottom surface of the transverse plate 4, a water quality sensor 10 is installed on the bottom surface of the placement block 9, and the water quality sensor 10 is located in the filter cage 8.

[0017] Specifically, both sides of the top surface of the bottom plate 1 are provided with limit screws 11, and the bottom ends of the limit screws 11 can be driven into the ground. The limit screws 11 have a limiting and fixing effect on the bottom plate 1, thereby ensuring the stability of the bottom plate 1.

[0018] Specifically, the four corners of the bottom surface of the bottom plate 1 are all equipped with pointed protrusions 12. The pointed protrusions 12 can be driven into the ground to further limit and fix the bottom plate 1, thereby further improving the stability of the bottom plate 1.

[0019] Specifically, a control box 13 is installed on one side of the L-shaped plate 2. The control box 13 is provided with a PLC control module, a signal processing module, a battery pack and a signal transmission module. The control box 13 is respectively connected to the telescopic rod 3 and the water quality sensor 10. The control box 13 can control the operation of the device.

[0020] Example:

[0021] When using the device, first install and fix the bottom plate 1 on the monitoring platform, and then control the telescopic rod 3 to extend downward through the control box 13. The extension of the telescopic rod 3 drives the horizontal plate 4 to move downward, and the movement of the horizontal plate 4 drives the water quality sensor 10 to move downward. The water quality sensor 10 contacts the water surface and extends underwater, thereby monitoring the water quality. The filter network 9 can filter and block large particles in the water, thereby avoiding damage to the water quality sensor. When the monitoring is completed and the water quality sensor 10 is no longer needed to stay in the water, the telescopic rod 3 retracts upward, thereby driving the water quality sensor 10 to move upward and then leave the water surface.

[0022] The utility model has a simple structure and is easy to use. The water quality sensor can be driven to move up and down through the extension and contraction of the telescopic rod, thereby adjusting the position of the water quality sensor to monitor water quality at different depths. At the same time, the water quality sensor can be moved out of the water when not in use, thereby avoiding long-term contact between the water quality sensor and water, reducing the influence of substances in the water on the water quality sensor. At the same time, in conjunction with the filtering network, it can block objects in the water, further reducing the influence of substances on the water quality sensor, thereby bringing convenience to use.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
