Description

Technical Field

[0001] The utility model relates to the technical field of sludge detection, in particular to a rainwater pipe sludge detection structure. Background Art

[0002] Municipal stormwater pipes generally discharge rainwater and accumulated water on the road into surrounding rivers or into drainage systems. The rainwater and accumulated water discharged into the stormwater pipes contain mud, etc. The long-term use of stormwater pipes will cause mud to accumulate and form silt.

[0003] The Chinese utility model patent with announcement number CN218329720U proposes an intelligent sludge detection device for municipal drainage pipes, including a municipal pipe, the top of which is movably connected to a fixed mounting plate, the bottom of which is fixedly connected to a detection device body, the top of which is fixedly connected to a servo motor, the inside of the detection device body is movably connected to a telescopic detection rod, and the telescopic detection rod and the servo motor are movably connected to each other through a screw thread; this scheme enables the detection device body and the pipe to be stable and in a vertical state through the contact between the fixed mounting plate and the top of the municipal pipe, which is convenient for measurement. However, since no limiting mechanism is set between the fixed mounting plate and the municipal pipe, the telescopic detection rod is easy to deviate from the center position of the municipal pipe, resulting in deviations in the detection results. In addition, this device requires electricity to work, but the municipal pipe is outdoors, which is inconvenient to power the device, and has low practicality.

[0004] To this end, the utility model provides a rainwater pipe silt detection structure. Utility Model Content

In addition, the detection structure does not require electricity to work, which improves the practicability of the detection structure.

[0012] Furthermore, the detection tube is a transparent acrylic tube, and the bottom of the detection tube is the 0 scale.

[0013] The beneficial effects of the utility model are as follows: the pressure plate of the sludge detection structure of the rainwater pipe of the utility model drives the rubber pad to squeeze the inner wall of the pipe mouth under the torsion force of the torsion spring shaft, and the positioning cover is conveniently fixed through the friction between the arc surface of the rubber pad and the pipe mouth and the pressure of the pressure plate, and the detection tube and the collecting rod can be positioned by the positioning cover to ensure that the collecting rod is in the center of the pipe mouth, thereby reducing the error, and the detection structure does not need electricity to work, which improves the practicality of the detection structure; the sludge inside the rainwater pipe body can be collected by the collecting rod and the collecting groove, and the internal sludge of the collecting groove can be blocked by the detection tube, so that the sludge depth in the rainwater pipe body can be detected according to the scale of the sludge position.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a rainwater pipe silt detection structure, comprising a structural body and a rainwater pipe body 1, the structural body is installed on the top of the rainwater pipe body 1 through a limiting mechanism, the structural body comprises a positioning cover 3, a detection tube 6 is movably installed at the center of the positioning cover 3, a collecting rod 7 is slidably installed inside the detection tube 6, collecting grooves 9 are symmetrically opened on both sides of the bottom end of the collecting rod 7, and scale lines 10 are arranged on the outer wall of the detection tube 6, the limiting mechanism comprises a pressing plate 5 and a rubber pad 8, and after the positioning cover 3 is installed on the top of the pipe mouth 2, it is convenient to position the detection tube 6 and the collecting rod 7, so as to ensure that the detection tube 6 and the collecting rod 7 are in the center of the pipe mouth 2, thereby reducing errors and improving the accuracy of the detection results.

[0021] In this embodiment, a pipe mouth 2 is provided at the top of the rainwater pipe body 1, and the pipe mouth 2 is the water inlet of the rainwater pipe body 1. The positioning cover 3 is covered on the top of the pipe mouth 2, and the bottom ends of the detection tube 6 and the collecting rod 7 are arranged inside the pipe mouth 2 and the rainwater pipe body 1. The positioning cover 3 and the pipe mouth 2 can limit each other to prevent the positioning cover 3 from sliding on the pipe mouth 2, thereby facilitating the subsequent detection of the silt depth inside the rainwater pipe body 1.

[0022] In this embodiment, mounting grooves 4 are symmetrically opened inside the two ends of the positioning cover 3, and the pressure plate 5 is movably installed inside the mounting groove 4 through a torsion spring shaft. The shape of the pressure plate 5 is "V"-shaped, and the rubber pad 8 is fixedly arranged on the side wall of the bottom end of the pressure plate 5. The shape of one side of the rubber pad 8 is arc-shaped, and the arc-shaped surface of the rubber pad 8 contacts the inside of the pipe mouth 2. The arc-shaped surface of the rubber pad 8 is a rough surface. Under the torsion force of the torsion spring shaft, the pressure plate 5 drives the rubber pad 8 to squeeze the inner wall of the pipe mouth 2, thereby increasing the friction between the pressure plate 5 and the pipe mouth 2, thereby facilitating the limiting of the positioning cover 3 and improving the stability of the detection structure.

[0023] In this embodiment, the detection tube 6 is a transparent acrylic tube, the bottom of the detection tube 6 is 0 scale, the top and bottom of the collecting tank 9 are both provided with slopes, and a sealing rubber ring is fixedly provided on the inner wall of the bottom end of the detection tube 6 corresponding to the outer side of the collecting rod 7. The sealing rubber ring can seal the detection tube 6 and the collecting rod 7 to prevent the sludge collected in the collecting tank 9 from leaking, which is convenient for subsequent detection of the sludge depth. The slope is convenient for cleaning the sludge in the collecting tank 9, and the transparent acrylic tube is convenient for direct observation of the sludge depth.

[0024] When the rainwater pipe sludge detection structure is used, the torsion spring shaft itself has torsion in the natural state, and the pressing plate 5 is pressed downward on the top of the positioning cover 3, and the pressing plate 5 drives the torsion spring shaft and accumulates force, and the positioning cover 3 is installed on the top of the pipe mouth 2, and the pressing plate 5 is loosened. The pressing plate 5 rotates in the opposite direction under the torsion of the torsion spring shaft and drives the rubber pad 8. Under the torsion of the torsion spring shaft, the rubber pad 8 squeezes the inner wall of the pipe mouth 2, and the friction between the curved surface of the rubber pad 8 and the pipe mouth 2 and the pressure of the pressing plate 5 are convenient to fix the positioning cover 3, thereby improving the stability of the positioning cover 3 and preventing the positioning cover 3 from shaking. The positioning cover 3 can be used to position the detection tube 6 and the collecting rod 7 to ensure that the collecting rod 7 is in the center of the pipe mouth 2, thereby reducing the error, and the detection structure does not need electricity to work, which improves the practicality of the detection structure; when installing the positioning cover 3, the detection tube 6 and the collecting rod 7 are moved to the top, and the detection tube 6 is manually adjusted. The collecting rod 7 is fixed, and the collecting rod 7 is pressed downward. The bottom end of the collecting rod 7 drives the collecting tank 9 to be inserted into the silt, and the silt will enter the inside of the collecting tank 9. After standing for a period of time, the silt inside the collecting tank 9 is flush with the silt inside the rainwater pipe body 1. The collecting rod 7 is fixed, and the detection tube 6 is pressed downward. The detection tube 6 slides downward on the outside of the collecting tank 9 and blocks part of the silt inside the collecting tank 9. After the bottom end of the detection tube 6 contacts the bottom of the inner side of the rainwater pipe body 1, the detection tube 6 and the bottom end of the collecting rod 7 are sealed by the sealing rubber ring, and the pressure plate 5 is pressed to separate the rubber pad 8 from the pipe mouth 2. At the same time, the positioning cover 3, the collecting rod 7 and the detection tube 6 are pulled upward to separate the structural main body from the rainwater pipe body 1, and the collecting rod 7 and the detection tube 6 are kept in a vertical state. The scale line 10 corresponding to the silt inside the collecting tank 9 is observed through the detection tube 6. The reading of this scale is the depth of the silt inside the rainwater pipe body 1.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
