Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a novel filtering structure of a sewer shaft. Background Art

[0002] Whenever the flood season comes, in order to prevent the blockage of sewer wells and cause urban waterlogging, the road sewer wells are usually dredged and desilted to ensure that rainwater can be discharged normally when heavy rain comes and to check whether the manhole covers on the road are safe. Most wells require regular manual inspection and cleaning. A few wells are equipped with automatic detection systems. The most important point is that there will be filter baffles in the wells. Currently, most filter baffles are fixed. If the filtering density of the filter baffle is too large, debris will easily clog and cause poor drainage. If the filtering density of the filter baffle is too small, the filtering effect will be greatly reduced, and more debris will enter the pipe, causing more debris in the pipe. Utility Model Content

[0003] The utility model provides a novel filtering structure for a sewer shaft, which can solve the problems pointed out in the background technology.

[0004] A novel filtering structure for a sewer shaft comprises a fixed filtering baffle built into the shaft, a movable filtering baffle located above the fixed filtering baffle, and a driving mechanism. One end of the movable filtering baffle is hingedly connected to the inner wall of the shaft. The movable filtering baffle is hingedly moved by the driving mechanism so that it can be overlapped and separated with the filtering baffle and the fixed filtering baffle, thereby increasing the filtering density by overlapping.

[0005] Preferably, the driving mechanism is an electric winch, which is connected to the other end of the movable filtering baffle through a winch rope.

[0006] Preferably, a sludge thickness sensor is provided below the fixed filter baffle.

[0007] Preferably, an infrared sensor is provided above the fixed filtering baffle.

[0008] Preferably, the driving mechanism, sludge thickness sensor and infrared sensor are all connected to a control system.

[0009] Beneficial effects: The utility model provides a new filtering structure for the sewer shaft, and is provided with a movable filtering baffle. When there is a lot of rain in summer, etc., the control system controls the movable filtering baffle to be in an open state, giving priority to drainage to ensure smooth drainage; at other times, the control system controls the movable filtering baffle to overlap with the fixed filtering baffle, the filtering density is increased, and debris can be effectively prevented from entering the pipeline.

[0014] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0015] Embodiment 1:

[0016] like Figure 1-2 As shown, a new filtering structure of a sewer shaft comprises a fixed filtering baffle 1 built into the shaft, a movable filtering baffle 2 located above the fixed filtering baffle 1 and a driving mechanism 3. One end of the movable filtering baffle 2 is hingedly connected to the inner wall of the shaft. The movable filtering baffle 2 is driven by the driving mechanism 3 to hinge so that it can be overlapped and separated with the filtering baffle 1 and the fixed filtering baffle 1, and the filtering density is increased by overlapping. A supporting member 7 is provided at a corresponding position of the inner wall of the shaft, and the fixed filtering baffle 1 is supported by the supporting member 7. One end of the movable filtering baffle 2 is hingedly connected by a rotating pin 8, and the rotating pin 8 is a detachable pin, so that the movable filtering baffle 2 can be freely disassembled and assembled, and the filtering density of the movable filtering baffle 2 can be greater than the filtering density of the fixed filtering baffle 1.

[0017] Specifically, the driving mechanism 3 is an electric winch, which is connected to the other end of the movable filtering baffle 2 through a winch rope.

[0018] In some embodiments, a sludge thickness sensor 4 is provided below the fixed filter baffle 1. The sludge thickness sensor 4 may be an ultrasonic sludge interface sensor for detecting the sludge thickness and notifying the backstage personnel when the sludge thickness reaches a set thickness.

[0019] In some embodiments, an infrared sensor 5 is provided above the fixed filtering baffle 1, and an alarm notification can be automatically issued if a person accidentally falls into the well.

[0020] The driving mechanism 3, the sludge thickness sensor 4, and the infrared sensor 5 are all connected to the control system 6. The control system 6 can be based on PLC. The control system 6 is connected to the background display control system 10 through the network communication module 9. The background performs corresponding data display, data alarm and remote control. The network communication module 9 can be based on Ethernet communication.
