Description

Technical Field

[0001] The utility model relates to a drainage pipe mud measuring device, belonging to the field of municipal equipment. Background Art

[0002] A municipal drainage pipe mud meter is a tool used to detect and clean blockages (such as mud, sand, grease, etc.) in municipal drainage pipes. It usually consists of a movable device and related sensors, which can accurately measure and record the amount and location of sediments in the pipe. The main function of the mud meter is to help urban management departments implement pipeline maintenance and cleaning plans. By regularly using the mud meter to conduct pipeline inspections, the sediment situation in the pipe can be understood in a timely manner, and targeted cleaning work can be carried out to ensure the smooth and normal operation of the drainage system.

[0003] In the prior art, the measuring end of the mud gauge is extended from the top of the drainage pipe to the bottom of the pipe to measure the silt depth inside the pipe. Due to the poor fluidity of the silt, the silt level inside the drainage pipe is inclined during the measurement process. If the measuring end of the mud gauge cannot be located at the center of the pipe for measurement, there will be a large error between the measurement position and the height of the silt level on the other side of the pipe, thereby resulting in a large error in the final measurement data of the mud gauge.

[0004] In summary, the utility model provides a drainage pipe mud meter to solve the above problems. Utility Model Content

[0025] See also Figure 2-5 The elastic pipe clamp seat 8 includes a fixed seat 81, which is fixedly connected to the top of the mounting plate 1 and located on one side of the chassis 3. The fixed seat 81 is fixedly connected to a spring 82 on the side away from the chassis 3. The spring 82 is fixedly connected to a moving block 83 at one end away from the fixed seat 31 and located just above one of the slide slots 2. The bottom of the moving block 83 is fixedly connected to a slider 84 located inside the slide slot 2. The bottom of the slider 84 is fixedly connected to a movable seat 85 located at the bottom of the mounting plate 1. The bottom of the movable seat 85 is fixedly connected to the bottom of the movable seat 85. A clamping plate 86 is fixedly connected, and the top-view cross-section of the clamping plate 86 is arc-shaped. The arc-shaped inner concave surface of the clamping plate 86 is fixedly connected with an anti-skid rubber pad 87. The surface of the anti-skid rubber pad 87 is injection-molded with wavy raised patterns, thereby increasing the friction between the anti-skid rubber pad 87 and the outer surface of the drainage pipe. The top of the moving block 83 is fixedly connected with a handle 88, the slider 84 is slidably connected to the slide groove 2, the bottom of the moving block 83 contacts the top of the mounting plate 1, and the top of the movable seat 85 contacts the bottom of the mounting plate 1.

[0026] Specific implementation method: Hold the handles 88 inside the two elastic pipe clamps 8 with both hands, and pull the two moving blocks 83 to both sides to stretch the two springs 82. The two moving blocks 83 slide to both sides inside the two slide grooves 2 through the two sliders 84, so that the two clamps 86 can be driven to move to both sides through the two movable seats 85, so as to expand the distance between the two clamps 86, and lift the mud meter upward as a whole through the two handles 88, place the measuring tube 7 into the municipal drainage pipe and make the pipe between the two clamps 86, and make the bottom of the mounting plate 1 contact with the port of the pipe, and then release it. The two clamping plates 86 drive the two moving blocks 83 to move closer through the resilience of the spring 82, so that the distance between the two clamping plates 86 can be reduced. The two clamping plates 86 clamp the municipal drainage pipe port through the anti-skid rubber pad 87. After the sludge is washed and settled inside the pipe with the water flow, the surface of the anti-skid rubber pad 87 is made of wavy convex patterns through injection molding, so that the friction between the anti-skid rubber pad 87 and the outer pipe surface of the drainage pipe can be increased, and the stability of the clamping plate 86 clamping the drainage pipe port can be improved. Then, the output end of the motor 4 is turned clockwise to drive the driving screw 6 to rotate clockwise. Since the outer ring surface of the top of the measuring tube 7 is a circular convex ring The measuring tube 7 is slidably connected with the limit tube 5 on both sides through long protrusions. When the driving screw 6 rotates forward and backward, the measuring tube 7 can be driven to move up and down, so that the measuring tube 7 moves downward from the center of the pipeline. When the top of the measuring tube 7 contacts the bottom of the inner wall of the pipeline, the highest position of the sludge will stick to the scale of the measuring tube 7, and the motor 4 is paused. Then, the clamping plates 86 are pulled to both sides through the two handles 88 at the same time, the elastic pipe clamping seat 8 is loosened, and the mounting plate 1 is moved upward as a whole through the two handles 88, so that the measured measuring tube 7 can be removed from the inside of the pipeline, and the scale position of the highest water level of the sludge can be recorded, so that After measuring the silt depth inside the municipal drainage pipe, the switch at the output end of the motor 4 is turned counterclockwise to start the measuring tube 7, and a sealing rubber ring is provided at the connection between the limit tube 5 and the measuring tube 7. The sealing rubber ring can be used to scrape off the mud on the surface of the measuring tube 7 when the measuring tube 7 moves upward by utilizing the close sealing performance between the sealing rubber ring and the measuring tube 7. When the pipe is installed in a horizontal position, the silt inside will still be in an inclined state due to its poor fluidity. The measuring tube 7 can be centered in the center of the pipe through two elastic pipe clamps 8, thereby effectively reducing the measurement error caused by the inclination of the silt horizontal surface.

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.
