AI Technical Summary
Existing wheeled/tracked pipe climbing machines cannot achieve precise positioning and re-inspection within water conservancy pipelines, resulting in data gaps and blind spots in detection, making it difficult to track deformation development at specific locations, and existing solutions increase equipment complexity or size.
The main frame of the equipment uses multiple support arms to rotate and install tracks. The tracks move and the laser displacement sensor rotates and scans by rotating the main shaft clockwise and counterclockwise. The transmission chain is separated by a ratchet mechanism, and only one drive motor is needed to realize the movement and detection functions.

TECHNICAL FIELD
[0001] The present application relates to the technical field of pipeline detection equipment, in particular to a water conservancy pipeline facility deformation detection equipment. BACKGROUND
[0002] Water conservancy project is a key component of national infrastructure construction, and the pipeline system such as water delivery pipeline, drainage pipe network and dam body culvert bears the core function of water resource transportation, distribution and discharge. Due to the influence of long-term internal pressure, external load, foundation settlement, corrosion and geological activity, the pipeline is prone to structural deformation, which may lead to leakage, pipe explosion and even system paralysis.
[0003] With the aging of urban water conservancy facilities, the demand for pipeline inner wall deformation detection is increasing. The existing wheeled / track crawler pipe climbing machine has obvious defects due to the continuous walking characteristics: it cannot accurately position the same coordinate point for rechecking during the walking process, resulting in data faults in 360° omnidirectional scanning of the pipeline inner wall, especially difficult to track the deformation development of the specific position. To solve the scanning coverage problem, the existing technology usually adopts two schemes: one is to add an independently rotating detection probe, but an additional motor and control system are needed, which increases the complexity and failure rate of the equipment; the other is to configure multi-angle fixed probes, which increases the size of the equipment and has detection blind area.
[0004] However, in fact, the internal space of most water conservancy pipelines is narrow, and these schemes are difficult to ensure miniaturization in the pipeline while realizing high-precision fixed-point rechecking, so an integrated mechanism is needed to solve the walking and fixed-point scanning requirements without increasing the driving source. Therefore, we provide a water conservancy pipeline facility deformation detection equipment to solve the above-mentioned problems. SUMMARY

[0014] The water pipeline facility deformation detection equipment has a first bevel gear mechanism including a first bevel gear ring fixed to the rotating cylinder and a first bevel gear fixed to one end of the first transmission shaft, and the first bevel gear ring is in engagement with the first bevel gear.
[0015] The water pipeline facility deformation detection equipment has a second bevel gear mechanism including a second bevel gear fixed to the other end of the first transmission shaft and a second bevel gear ring fixed to the second transmission shaft, and the second bevel gear ring is in engagement with the second bevel gear.
[0016] The water pipeline facility deformation detection equipment has the beneficial effects that: when in use, the equipment main frame body is fixed with a plurality of support arms on the circumferential side, a track belt abutting against the inner wall of the pipeline is rotatably installed on each support arm, a rotation detection ring is rotatably arranged at the port of the equipment main frame body, a laser displacement sensor is fixed on the rotation detection ring, and a main shaft is rotatably arranged in the equipment main frame body, when the driving main shaft rotates clockwise, the track belt rotates on the support arm to drive the equipment main frame body to travel inside the pipeline, and when the driving main shaft rotates counterclockwise, the rotation detection ring rotates counterclockwise to drive the laser displacement sensor to rotate along the rotation detection ring to detect the deformation of the inner wall of the pipeline.
[0017] The second linkage structure comprises a second ratchet inner ring gear fixed on the inner wall of the rotation detection ring and a second driving disc fixed on the main shaft, the second driving disc is hinged with a second pawl, the second driving disc is fixed with a second spring limiting piece abutting against one side wall of the second pawl, and the second pawl is in movable engagement with the teeth of the inner edge of the second ratchet inner ring gear.
[0018] Compared with the prior art, the water pipeline facility deformation detection equipment has the beneficial effects that: when in use, the equipment main frame body is fixed with a plurality of support arms on the circumferential side, a track belt abutting against the inner wall of the pipeline is rotatably installed on each support arm, a rotation detection ring is rotatably arranged at the port of the equipment main frame body, a laser displacement sensor is fixed on the rotation detection ring, and a main shaft is rotatably arranged in the equipment main frame body, when the driving main shaft rotates clockwise, the track belt rotates on the support arm to drive the equipment main frame body to travel inside the pipeline, and when the driving main shaft rotates counterclockwise, the rotation detection ring rotates counterclockwise to drive the laser displacement sensor to rotate along the rotation detection ring to detect the deformation of the inner wall of the pipeline.

When the second pawl 26 rotates, the second pawl 26 is engaged with the second ratchet inner ring 24, which drives the second ratchet inner ring 24 to rotate synchronously, thereby driving the rotation detection ring 22 to rotate synchronously. The surface of the second pawl 26 is treated with a tungsten carbide coating to increase wear resistance.
