The application provides an underwater fixed-distance luring camera device for shrimp culture, and relates to the technical field of aquaculture monitoring equipment. The underwater fixed-distance luring camera device comprises a water control terminal and an underwater collecting unit. The underwater collecting unit comprises a support connecting arm, and the support connecting arm is provided with an underwater camera module, a light supplementing assembly and a luring module. An observation cover plate is arranged on the shooting direction of the underwater camera module. A feeding outlet of the luring module is arranged towards the disc surface of the observation cover plate, and is used for feeding bait on the observation disc. The water control terminal comprises an intelligent main control terminal and an antenna. The application physically locks the shooting area in the best focal length range of the camera by using the observation cover plate, and enhances the picture by combining with an algorithm, so that the technical problem that ordinary cameras are difficult to capture clear images under water due to the fast swimming speed and uncertain position of shrimps is effectively solved.

The invention discloses a double-layer sewage disposal device for a culture pond. The double-layer sewage disposal device comprises a mounting seat, a sewage disposal mechanism and a driving mechanism, the sewage disposal mechanism comprises a connecting sleeve, a pool bottom sewage disposal assembly and a water surface sewage disposal assembly; the water surface sewage disposal assembly comprises a telescopic pipe, an upper sewage disposal pipeline and a floating ball fixed to the upper end of the telescopic pipe, the lower end of the telescopic pipe is communicated with the connecting sleeve, the upper end of the telescopic pipe is communicated with the upper sewage disposal pipeline, and the floating ball enables the upper sewage disposal pipeline to float on the water surface; the pool bottom sewage suction assembly comprises a lower sewage cleaning pipeline and a cleaning brush, one end of the lower sewage cleaning pipeline is communicated with the connecting sleeve, and the other end of the lower sewage cleaning pipeline extends outwards to be provided with a lower sewage suction opening; the driving mechanism drives the connecting sleeve to rotate, so that the pool bottom cleaning assembly and the water surface cleaning assembly are used for cleaning the pool bottom and the water surface respectively; a sewage suction pump does not need to be additionally mounted to suck cleaned stains out of the culture pond, so that the culture pond is cleaned in a more energy-saving manner, manual cleaning of the culture pond is replaced, the operation is simpler and more convenient, and water resources are saved.
