Description

Technical Field

[0001] The invention relates to the technical field of drainage pipelines, and in particular to a non-destructive fixing device for monitoring drainage pipelines and an installation method thereof. Background Art

[0002] With the population growth and the acceleration of urbanization, urban water supply and drainage systems are facing greater pressure and need to meet the water needs of more residents and commercial activities. In recent years, the urban lifeline system, including water supply, power supply, gas supply, communication and transportation, is the basis for the normal operation of the city. Its construction and maintenance are crucial to ensuring urban safety.

[0003] With the introduction of the concept of smart city, the construction of urban lifeline systems has paid more and more attention to intelligence, and the real-time monitoring and efficient maintenance of key urban infrastructure are achieved through integrated management systems. At present, the drainage pipe systems in many cities were built decades ago. As time goes by, the pipe materials age and are prone to rupture, leakage and other problems. Long-term monitoring of drainage pipes, timely detection of pipe problems and pipeline maintenance are the prerequisites for ensuring the safety of urban lifelines.

[0004] Drainage monitoring equipment generally needs to be installed inside the pipeline. Due to the purpose and material characteristics of the drainage pipeline, the use of conventional anchor fixing devices will destroy its original structure and affect the original structural safety of the drainage pipeline. It is a hidden danger to the safe operation of the pipeline. In addition, the installation of the fixing device requires frogmen to enter the inside of the pipeline, which is inefficient. Summary of the invention

[0005] The purpose of the present invention is to provide a non-destructive fixing device for drainage pipeline monitoring and an installation method thereof based on the above-mentioned deficiencies of the prior art. By designing a gear push-pull ring structure, the pipeline is pushed into the well chamber, and after reaching the fixed position, the driving rod is shaken. The driving rod drives the gear to rotate, so that the diameter of the ring is expanded, and the force on the gear is displayed. When the force reaches the preset value, the fixation is completed.

[0006] The purpose of the present invention is achieved by the following technical solutions: A non-destructive fixing device for drainage pipeline monitoring, characterized in that: the non-destructive fixing device includes a high-strength circular hoop, an upper push-pull track and a lower push-pull track are arranged on the high-strength circular hoop, a transmission gear is arranged between the upper push-pull track and the lower push-pull track, the transmission gear forms a gear meshing with the upper push-pull track and the lower push-pull track, under the rotation drive of the transmission gear, the upper push-pull track and the lower push-pull track move in opposite directions, so that the diameter of the high-strength circular hoop changes, the transmission gear is provided with a push-type gear lock buckle, and the push-type gear lock buckle is used to lock the transmission gear.

[0007] The push-type gear lock buckle is connected with a push-type gear lock buckle button.

[0008] The non-destructive fixing device comprises a push rod matched with the high-strength circular hoop, and the push rod is used to push the high-strength circular hoop into the designed arrangement position in the drainage pipeline.

[0009] With the transmission gear as the center, a fixing buckle is set every 90 degrees on the high-strength hoop to fix the push rod. The push rod is connected to the high-strength hoop through the top quick disassembly buckle to send the high-strength hoop into the pipe and fix the position and posture of the high-strength hoop.

[0010] The non-destructive fixing device comprises a transmission rod matched with the transmission gear, and the transmission rod is used to drive the transmission gear to rotate.

[0011] A transmission fixing buckle is arranged on the transmission gear for fixing the transmission rod.

[0012] The transmission rod is provided with a snap lock button for ejecting and retracting the push-type gear lock.

[0013] A method for installing the above-mentioned non-destructive fixing device for monitoring drainage pipelines, characterized in that the installation method comprises the following steps: Use a push rod to push the high-strength round hoop into the pipe of the drainage line until it is pushed to a fixed installation position; The push rod is kept in a state so that the position and posture of the high-strength round hoop are fixed, and the push rod is inserted into the transmission rod so that the transmission rod is connected to the transmission gear; The transmission gear is rotated by rotating the transmission rod, and the transmission gear drives the diameter of the high-strength hoop to increase until the high-strength hoop is tightly fitted to the inner wall of the pipe; The transmission gear is locked by using a push-type gear lock; The transmission rod and the push rod are recovered to complete the installation.

[0019] Example: Figures 1 to 5 As shown, the non-destructive fixing device for monitoring the drainage pipeline in this embodiment includes a high-strength round hoop 1, an upper push-pull track 2, a lower push-pull track 3, a transmission lock 4, a push-type gear lock button 5, a push-type gear lock 6, a round steel gear 7, a push rod 8, a push rod 9, a push rod 10, a push rod 11, and a transmission rod 12. Among them, the push rod 8, the push rod 9, the push rod 10, the push rod 11 and the transmission rod 12 are installation components, that is, components used to realize the installation of the high-strength round hoop 1.

[0020] Specifically, the non-destructive fixing device in this embodiment includes the following installation method: 1) Collect information on pipe diameter design dimensions, pipe diameter construction dimensions, etc. to preliminarily confirm the pipeline diameter.

[0021] 2) Open the well chamber on site to detect the diameter of the drainage pipeline again and reconfirm the pipeline size.

[0022] 3) After determining the diameter of the drainage pipe, select a high-strength circular hoop 1 of appropriate size, open the well chamber at a nearby well chamber, and place the appropriate high-strength circular hoop 1 into the well chamber.

[0023] 4) Fix push rods 8, 9, 10 and 11 on the high-strength hoop 1 in a cross arrangement, push each push rod, and slowly move the high-strength hoop into the pipeline in a fixed posture, and push it to the position to be fixed and installed. Adjust the position of each push rod, place the push-pull track directly above the pipeline, fix the push rod, and fix the position and angle of the high-strength hoop 1 in the pipeline.

[0024] 5) Control the four push rods to fix the position of the high-strength round hoop 1, extend the transmission rod 12 to the transmission lock 4 of the circular steel gear 7, align the red dot above the transmission rod 12 with the push-type gear lock button 5 on the transmission lock 4, push the transmission rod hard, rotate the transmission rod 12, and the transmission rod 12 is connected to the circular steel gear 7.

[0025] 6) Turn the transmission rod 12 clockwise to make the internal circular steel gear 7 rotate with the transmission rod 12. The circular steel gear 7 is connected with the gears of the upper push-pull track 2 and the lower push-pull track 3, pushing the gears of the push-pull track to rotate, the upper push-pull track 2 moves to the left, and the lower push-pull track 3 moves to the right, so that the diameter of the high-strength round hoop 1 becomes larger, and the transmission rod 12 continues to be rotated until the transmission rod 12 displays the maximum pressure. The handle of the rotating rod 12 will automatically unload the force, and the button on the transmission rod 12 will be pressed to trigger the push-type gear lock buckle 5 to pop out, control the position of the circular steel gear 7, and prevent the circular steel gear 7 from rotating under force.

[0026] 7) Remove the transmission rod 12 and each push rod for recycling to complete the installation.
