Description

Technical Field

[0001] The invention belongs to the technical field of aquatic ecological environment, and in particular relates to an aquatic ecological environment detection platform. Background Art

[0002] Water pollution is the reduction or loss of water's use value caused by harmful chemicals, which pollutes the environment. Acids, alkalis, oxidants, compounds such as copper, cadmium, mercury, arsenic, and organic toxins such as benzene, ethylene dichloride, and ethylene glycol in sewage can kill aquatic organisms, affecting drinking water sources and scenic landscapes. Organic matter in sewage consumes oxygen in the water when decomposed by microorganisms, affecting the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, organic matter undergoes anaerobic decomposition, producing unpleasant gases such as hydrogen sulfide and mercaptans, further deteriorating the water quality.

[0003] According to a publicly disclosed water ecological environment detection platform (publication number: CN117434237A), it includes a floating structure, a water body detection device, a transmitting device, an energy storage device and a general control structure. The floating structure includes a floating body and a sealing cover body. The energy storage device includes an energy storage panel mounting frame, a solar energy storage panel group, a wind turbine generator set arranged on the upper part of the energy storage panel mounting frame, and an energy storage battery. The general control structure controls the transmitting device and the water body detection device. However, in the above-mentioned device, it is difficult to achieve the effect of fixing the detection platform after adjusting the height of the detection platform through the mutual cooperation of components such as the transmitting device, the energy storage device and the general control structure. It is difficult to adjust the height of the detection platform according to actual needs. It is difficult to ensure the stability of the detection platform during use. It is difficult to avoid errors or detection failures caused by platform instability. There is room for improvement. Summary of the invention

[0017] 1. The present invention uses a motor to drive the telescopic rod to rotate, and the force of the threaded rod, the fixed rod and the rotating rod in the adjusting device cooperate with each other, so that the threaded rod threadedly connected to the protective shell is driven to rotate by the rotation of the telescopic rod, so that the threaded rod is displaced upward, and the fixed rod is driven upward by the upward displacement of the threaded rod, and then the detection platform is driven upward by the upward displacement of the fixed rod, so that the detection platform is fixed after the height of the detection platform is adjusted.

[0019] 3.

When the mounting block is away from the side of the fixed block, the positioning rod drives the scraper to reset through the elastic force of the spring, so that the scraper rotates continuously to prevent the filter holes from being blocked by solid particles. The solid particles on the filter plate can be continuously cleaned to prevent the filter holes from being blocked, thereby maintaining the permeability of the filter plate, and can effectively remove impurities accumulated in the filter holes, ensuring the unimpeded flow of water during the filtration process.
