Technical Field

[0001] The utility model relates to the field of drainage pipeline detection, in particular to a drainage pipeline detection device. Background Art

[0002] Drainage pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage and wastewater. This system includes main pipes, branch pipes, and pipes leading to treatment plants. Whether built on the street or elsewhere, as long as the pipes are used for drainage, they should be included in the statistics of drainage pipes.

[0003] Water quality testing is a key link in ensuring water quality safety and environmental protection. In particular, it is very important to inspect the water quality of drainage pipes. By confirming the quality of the water body, the types of pollutants in the water body are analyzed. If pollutants are found to exceed the standard, the sewage needs to be treated to prevent the sewage from entering the underground and polluting the groundwater and soil. When sampling the water quality of small drainage pipes, the conventional sampling method is that the sampling personnel go to the location of the drainage pipe discharge port, use containers to pack the water samples and bring them back to the laboratory, and then use water quality testing instruments for testing. This type of testing method is time-consuming and labor-intensive, and it is impossible to quickly detect the water body in real time. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5As shown, the utility model provides a drainage pipe detection device, a drainage pipe detection device, which includes a square pipe 1, both ends of the square pipe 1 are connected to the drainage pipe through a connecting pipe 2, a water storage structure is arranged inside the square pipe 1, the water storage structure includes a connecting tube 6 fixedly connected to the inside of the square pipe 1, both sides of the connecting tube 6 are provided with openings 61, a docking assembly is movably plugged on the connecting tube 6, the docking assembly includes a cover plate 7, and a docking piece 71 arranged at the bottom of the cover plate 7 and plugged and fixed with the connecting tube 6, two baffles 72 are symmetrically arranged at the bottom of the docking piece 71, and the outer walls of the two baffles 72 are in contact with the inner wall of the connecting tube 6; a water quality detector 5 is installed at the bottom of the square pipe 1, and the detection probe 53 of the water quality monitor extends into the connecting tube 6. An adjustment assembly is arranged on the side of the surface of the square pipe 1 away from the water storage structure, and the adjustment assembly can drive the docking assembly to rotate on the connecting tube 6, and the adjustment assembly at least includes a handle 10.

[0024] When the handle 10 is parallel to the length direction of the square tube 1, the midpoint line of the two baffles 72 and the midpoint line of the two openings 61 are perpendicular to each other;

[0025] When the handle 10 is perpendicular to the length direction of the square tube 1 , the central axis of the baffle 72 coincides with the central axis of the opening 61 , and the area of ​​the baffle 72 is larger than that of the opening 61 .

[0026] In this embodiment, the connecting tube 6 and the docking assembly are both cylindrical structures, and the docking piece 71 is plugged into and corresponds to the connecting tube 6. Under normal conditions, the midpoint line of the two baffles 72 is perpendicular to the midpoint line of the two openings 61, and the baffle 72 does not block the opening 61, so that the water flow in the drain pipe can flow between the two openings 61; in the detection state, the central axis of the baffle 72 coincides with the central axis of the opening 61, and the two openings 61 are completely blocked by the two baffles 72. The connecting tube 6 and the docking assembly are in a closed state, and the water inside them does not circulate with the outside, and the water flow inside the water storage structure is in a static state. At this time, the water quality detector 5 can be turned on to detect the water quality of the water body used in the water storage structure. The operation is convenient and quick, and the water quality of the drain pipe can be monitored in real time.

[0027] In some embodiments, the adjustment assembly also includes a transmission rod 8 passing through the surface of the square tube 1, and a bearing 9 arranged between the transmission rod 8 and the square tube 1, one end of the transmission rod 8 is welded and fixed to the center of the cover plate 7, and the other end of the transmission rod 8 extends to the outside of the square tube 1, and the handle piece 10 is fixedly welded to the other end of the transmission rod 8; the inner ring of the bearing 9 is fixedly connected to the surface of the transmission rod 8, and the outer ring of the bearing 9 is fixedly connected to the square tube 1.

[0028] The top view of the handle piece 10 is in the shape of a straight line. Since the handle is welded and fixed to the transmission rod 8, rotating the handle piece 10 can drive the transmission rod 8 to rotate, thereby driving the docking assembly to rotate and closing the water storage structure, so that the water flow inside it is in a static state, which is convenient for the water quality detector 5 to detect the water flow sample.

[0029] The bearing 9 is a waterproof stainless steel bearing 9. The waterproof bearing 9 is a sealing ring between the inner and outer rings on one or both sides of the bearing 9. The inner side of the sealing ring is in the shape of a ring groove. A spring hoop is hooped on the ring groove wall of the sealing ring close to the inner ring of the bearing 9. It has the characteristics of firm sealing, reliable waterproof, dustproof and oil retention.

[0030] Since the inner ring of the bearing 9 is fixedly connected to the surface of the transmission rod 8, and the outer ring of the bearing 9 is fixedly connected to the square tube 1, the transmission rod 8 can rotate on the square tube 1 while water leakage is not likely to occur at the connection between the transmission rod 8 and the square tube 1.

[0031] In some embodiments, the bottom of the square tube 1 is fixedly connected to a mounting frame 3 for placing a water quality monitor by screws, a waterproof box 4 is fixedly connected inside the mounting frame 3, a transparent plate 41 is rotatably connected to the front of the waterproof box 4, and the water quality monitor is placed inside the waterproof box 4.

[0032] In this embodiment, the mounting frame 3 and the square tube 1 are fixed by screws, which facilitates the disassembly of the mounting frame 3 for replacement. In other embodiments, the mounting frame 3 is fixedly welded to the bottom of the square tube 1, which can further strengthen the connection strength between the mounting frame 3 and the square tube 1.

[0033] The waterproof box 4 can protect the water quality monitor and effectively prevent humid gas from entering the water quality monitor and damaging its internal electrical components. The transparent plate 41 is made of PVC transparent plate 41 and is rotatably connected to the waterproof box 4 through hinges to isolate the water quality monitor from the outside world and prevent humid gas from invading. At the same time, the detection data displayed on the water quality monitor can be observed from the transparent plate 41.

[0034] In some embodiments, a power cord 51 is provided on one side of the bottom of the water quality monitor, and the power cord 51 is externally connected to a power source. A probe line 52 is provided on the other side of the bottom of the water quality monitor, and is electrically connected to a detection probe 53 through the probe line 52; a gap is left between the surface of the detection probe 53 and the baffle 72 to prevent the baffle 72 from scratching and wearing the surface of the detection probe 53 during movement.

[0035] In other embodiments, the detection probe 53 of the water quality monitor is movably inserted into the connecting tube 6. A socket is opened at the corresponding position of the connecting tube 6, and a waterproof rubber ring is glued to the socket. When no detection is needed, the handle 10 is rotated to be perpendicular to the length direction of the square tube 1, and the baffle 72 blocks the opening 61, so that water does not flow into the connecting tube 6. At this time, the detection probe 53 can be pulled out. When waiting for detection, the detection probe 53 can be reinserted into the socket. The probe fits the waterproof rubber ring, and water will not flow out of the socket during the detection process. This setting can facilitate the removal of the detection probe 53 for maintenance.

[0036] The working principle of this specific implementation is:

[0037] In the initial state, the water quality detector 5 is in the off state, the water from the drainage pipe enters the connecting pipe 2, and then enters the inside of the square tube 1 through the connecting pipe 2. When the water flows through the water storage structure in the process of flowing inside the square tube 1, it flows through an opening 61 on the connecting tube 6 to another opening 61 and then flows out; when testing the water quality, turn the handle 10 ninety degrees clockwise or counterclockwise to make it perpendicular to the length direction of the square tube 1. At this time, the central axis of the baffle 72 coincides with the central axis of the opening 61, and the two openings 61 are completely blocked by the two baffles 72. The water flow inside the water storage structure is in a static state. Then, open the transparent plate 41, turn on the water quality detector 5, and measure the content of various substances in the water sampled inside the water storage structure through the detection probe 53 to complete the use.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
