The utility model is suitable for sewage treatment technical field provides a kind of sewage treatment detection device, including;Transmission pipeline;Protective box, the protective box fixed mounting is at the top of transmission pipeline, and right end is established with transmission pipeline between opening;Supporting plate, the supporting plate fixed mounting is at the middle part of protective box;Chute, the chute is established in the top of protective box, and inside slidingly provided with slide plate;Detector main body, the detector main body slidingly is set in the top of supporting plate.Compared with prior art, the beneficial effects of the utility model are: and by setting plugging structure in the bottom of protective box, and linkage with displacement structure, and then when plugging structure opens, it will drive displacement structure to move, so that the detection probe of detector main body is extended, enters transmission pipeline and carries out sewage detection, then resets and closes, so as to protect detection probe, to avoid long time soaking in sewage, cause the emergence of damaged condition.

This invention provides a retractable, assembled concrete chute, relating to the field of concrete chute technology. The chute is composed of multiple individual chutes, each a cylindrical structure with one end larger than the other. Adjacent individual chutes are matched at their connecting ends. A chute assembly and fixing assembly is installed between adjacent individual chutes to fix them relatively. This assembly includes limiting members that are fixed to the individual chutes and connected to the limiting members of adjacent individual chutes. A vibrator is installed around the periphery of the individual chutes located in the middle of the chute. This invention allows for an adjustable number of individual chutes, thus changing the actual length of the assembled chute. Connected between the concrete mixer truck and the construction site, it adapts to complex mountainous terrain, is less restricted by road conditions, and effectively solves the problem of high dependence on pump trucks in large-volume continuous concrete construction. The retractable chute also facilitates transportation and storage.
