Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a full-spectrum water quality monitoring device capable of collecting samples at different water depths, and solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A full-spectrum water quality monitoring device capable of collecting samples at different water depths, including a housing, a base is fixedly installed at the bottom of the housing, floating rings are fixedly installed on both sides of the surface of the housing, a signal booster is fixedly installed at the top of the housing, a square hole is opened on the surface of the housing, and a detection device, a support device, and a wire winding device are arranged inside the housing;

By starting the rotation of the wire coil at different times, the height difference of the detectors entering the water is generated, so that one detector is at the top and the other detector is at the bottom.

[0008] According to the above technical solution, the adjustment block contacts the adjustment frame, and a detection port is opened on the surface of the base. The detector can sink into the water through the detector.

The first torsion spring drives the small rotating shaft to rotate, and the rotation of the small rotating shaft drives the telescopic bracket to rotate.

[0011] According to the above technical solution, a first torsion spring is provided between the small rotating shaft and the storage groove. The sliding rod contacts the transmission long rod, and the first torsion spring drives the small rotating shaft to reset.

The other end of the linkage rod is rotatably installed at the end of the round rod away from the transmission long rod. The rotating plate is fixedly installed at the end of the round rod away from the linkage rod. The movement of the linkage rod drives the movement of the long plate. The movement of the long plate drives the movement of the wire winding hook. The movement of the wire winding hook contacts the steel cable. After the wire winding hook contacts the steel cable, the friction force between them increases.

[0014] According to the above technical solution, the wire winding hook contacts the steel cable. A second torsion spring is provided between the round rod and the vertical rod, and the second torsion spring drives the round rod to reset.

[0015] The present invention provides a full-spectrum water quality monitoring device capable of collecting samples at different water depths. It has the following beneficial effects:

[0016] (1) In this invention, due to the different starting times of the rotation of the wire winding coil, the deviation of the water entry height between the detectors is generated, so that one detector is at the top and the other detector is at the bottom, enabling the detection of water quality at different heights simultaneously without the need for multiple detections, saving working time and improving work efficiency. By selecting the time point when the adjusting block contacts the adjusting frame when it rotates to 180 degrees or 270 degrees, the height difference between the detectors can be adjusted, and it is possible to detect the water surface and the bottom at different heights even in the face of different water depths, improving the practicability of the device.

[0017] (2) In this invention, when the support frame rotates, it will pass through the square hole and be stuck into the nearby wall, improving the stability of the device, preventing the device from shaking after the detector enters the water bottom, which may affect the detection area and the monitoring result, and enhancing the reliability of data monitoring. After the telescopic support rotates, it will be stuck into the nearby wall and assist the support frame in supporting, further improving the stability of the device.

[0018] (3) In this invention, when the wire-receiving hook moves and no longer contacts the steel cable, the steel cable will not be hindered when moving downward, facilitating the movement of the detector, ensuring the smoothness of the monitoring process, and enhancing the practicality of the device. When the wire-receiving hook contacts the steel cable, due to the increased friction between them, the steel cable will be slowly wound when being wound, preventing the steel cable from being damaged due to excessive load caused by rapid winding, and enhancing the protection of the device.
