Description

Technical Field

[0001] This invention relates to the field of pipeline inspection equipment technology, specifically to deformation inspection equipment for water conservancy pipeline facilities. Background Technology

[0002] Water conservancy projects are a key component of national infrastructure construction. Among them, pipeline systems, such as water transmission pipelines, drainage networks, and dam culverts, bear the core functions of water resource transportation, allocation, and discharge. Due to long-term exposure to factors such as internal pressure, external loads, foundation settlement, corrosion, and geological activity, pipelines are prone to structural deformation, which may lead to leakage, pipe bursts, or even systemic failure.

[0003] With the aging of urban water conservancy facilities, the demand for pipeline inner wall deformation detection is becoming increasingly prominent. Existing wheeled / tracked pipe climbers have significant drawbacks due to their continuous walking characteristics: they cannot accurately locate the same coordinate point for re-inspection during movement, resulting in data gaps in the 360° omnidirectional scan of the pipeline inner wall, making it particularly difficult to track the deformation development at specific locations. Current technologies typically employ two solutions to address the scanning coverage problem: one is to add an independently rotating detection probe, but this requires an additional drive motor and control system, increasing equipment complexity and failure rate; the other is to configure multi-angle fixed probes, leading to increased equipment size and the existence of detection blind spots.

[0004] However, in reality, most water conservancy pipelines have limited internal space, making it difficult for these solutions to achieve high-precision fixed-point re-inspection while miniaturizing the pipeline. Therefore, there is an urgent need for an integrated mechanism that can simultaneously solve the needs of travel and fixed-point scanning through mechanical linkage without adding a drive source. To this end, we provide water conservancy pipeline facility deformation detection equipment to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a deformation detection device for water conservancy pipeline facilities to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: Deformation detection equipment for water conservancy pipeline facilities includes a main frame, multiple support arms fixed around the periphery of the main frame, a track rotatably mounted on each support arm and attached to the inner wall of the pipeline, a rotating detection ring rotatably disposed at the port of the main frame, a laser displacement sensor fixed on the rotating detection ring, and a main shaft rotatably disposed inside the main frame. The main shaft and the track are connected by a first linkage structure. When the main shaft rotates clockwise, it will drive the track to rotate on the support arm to drive the main frame of the equipment to move inside the pipe. The main shaft and the rotating detection ring are connected by a second linkage structure. When the main shaft rotates counterclockwise, it will drive the rotating detection ring to rotate counterclockwise, thereby driving the laser displacement sensor to rotate along the circumferential direction of the rotating detection ring to detect the deformation of the inner wall of the pipe.

[0007] The water conservancy pipeline deformation detection equipment described above: a drive motor is fixedly installed inside the main frame of the equipment, and the output end of the drive motor is connected to the main shaft through a coupling to drive the main shaft to rotate.

[0008] The water conservancy pipeline deformation detection equipment described above: two rotating shafts are rotatably mounted on the support arm, and a transmission wheel is fixed on the rotating shaft. The track is sleeved on the transmission wheel and cooperates with the transmission wheel for transmission.

[0009] The water conservancy pipeline deformation detection equipment described above includes: the first linkage structure comprising a rotating drum rotatably disposed inside the main frame of the equipment; the rotating drum and the main shaft are driven by a first ratchet mechanism; when the main shaft rotates clockwise, it drives the rotating drum to rotate clockwise; when the main shaft rotates counterclockwise, the rotating drum does not rotate; a first transmission shaft and a second transmission shaft are rotatably disposed on the main frame of the equipment; the first transmission shaft and the rotating drum are driven by a first bevel gear mechanism; when the rotating drum rotates, it drives the first transmission shaft to rotate synchronously; the first transmission shaft and the second transmission shaft are driven by a second bevel gear mechanism; when the first transmission shaft rotates, it drives the second transmission shaft to rotate synchronously; the second transmission shaft and one of the rotating shafts are driven by a first pulley mechanism; when the second transmission shaft rotates, it drives the rotating shaft to rotate synchronously.

[0010] The water conservancy pipeline deformation detection equipment described above: The first ratchet mechanism includes a first ratchet internal gear ring fixed to the inner wall of the rotating drum and a first drive disk fixed to the main shaft. A first pawl is hinged on the first drive disk. A first spring limiting piece is fixed on the first drive disk and movably attached to one side wall of the first pawl. The first pawl is movably engaged with the gear teeth on the inner edge of the first ratchet internal gear ring.

[0011] The water conservancy pipeline deformation detection equipment described above: the first bevel gear mechanism includes a first bevel gear ring fixed on the rotating drum and a first bevel gear fixed at one end of the first transmission shaft, wherein the first bevel gear ring meshes with the first bevel gear.

[0012] The deformation detection equipment for water conservancy pipeline facilities as described above: the second bevel gear mechanism includes a second bevel gear fixed at the other end of the first transmission shaft and a second bevel gear ring fixed on the second transmission shaft, the second bevel gear ring meshing with the second bevel gear.

[0013] The water conservancy pipeline deformation detection equipment described above: the first pulley mechanism includes a first pulley fixed on a second transmission shaft and a second pulley fixed on a rotating shaft, and the first pulley and the second pulley are driven by a belt.

[0014] The deformation detection equipment for water conservancy pipeline facilities as described above: the second linkage structure includes a second ratchet internal gear ring fixed to the inner wall of the rotating detection ring and a second drive disk fixed to the main shaft. A second pawl is hinged on the second drive disk. A second spring limiting piece is fixed on the second drive disk and movably attached to one side wall of the second pawl. The second pawl is movably engaged with the gear teeth on the inner edge of the second ratchet internal gear ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, multiple support arms are fixed around the periphery of the main frame of the equipment, and a track that fits against the inner wall of the pipe is rotatably installed on each support arm. A rotating detection ring is rotatably installed at the port of the main frame of the equipment, and a laser displacement sensor is fixed on the rotating detection ring. A main shaft is rotatably installed inside the main frame of the equipment. When the main shaft is driven to rotate clockwise, it will drive the track to rotate on the support arm to drive the main frame of the equipment to move inside the pipe. When the main shaft is driven to rotate counterclockwise, it will drive the rotating detection ring to rotate counterclockwise, so that the laser displacement sensor will rotate circumferentially along the rotating detection ring to detect the deformation of the inner wall of the pipe. Thus, when the main shaft of this invention rotates clockwise, it drives the track to rotate and continuously travel along the inner wall of the pipe to the area to be inspected. When the main shaft rotates counterclockwise, it drives the rotating detection ring to rotate, causing the laser displacement sensor to rotate and scan 360°. At the same time, the track remains stationary because the first ratchet inner gear ring of the first ratchet mechanism is disengaged from the first pawl. This mechanism ensures that the equipment can be fixed in a specific position inside the pipe for displacement-free detection, which can eliminate the positioning detection error caused by the continuous movement of the equipment. At the same time, the rotation of the laser displacement sensor can be used to re-inspect the fixed position and perform 360° all-round scanning, resulting in a wide detection coverage and high detection accuracy. In addition, this invention only requires a drive motor to drive the main shaft to rotate clockwise or counterclockwise. The main shaft can rotate clockwise for movement and counterclockwise for detection simply by switching the direction of rotation of the main shaft. By utilizing the physical characteristics of the ratchet structure, the transmission chain of the track rotation and the transmission chain of the laser displacement sensor rotation can be automatically separated. Compared with the traditional method of adding a motor, reducing the drive source significantly reduces energy consumption and control system complexity. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-10 As an embodiment of the present invention, the deformation detection equipment for water conservancy pipeline facilities includes a main frame 1, a plurality of support arms 2 are fixed on the periphery of the main frame 1, a track 5 that fits against the inner wall of the pipeline is rotatably installed on each support arm 2, a rotating detection ring 22 is rotatably arranged at the port of the main frame 1, a laser displacement sensor 23 is fixed on the rotating detection ring 22, and a main shaft 6 is rotatably arranged inside the main frame 1. The main shaft 6 and the track 5 are connected by the first linkage structure. When the main shaft 6 rotates clockwise, it will drive the track 5 to rotate on the support arm 2 to drive the main frame 1 of the equipment to move inside the pipeline. The main shaft 6 and the rotating detection ring 22 are connected by a second linkage structure. When the main shaft 6 rotates counterclockwise, it will drive the rotating detection ring 22 to rotate counterclockwise, thereby driving the laser displacement sensor 23 to rotate circumferentially along the rotating detection ring 22 to detect the deformation of the inner wall of the pipe.

[0029] In this embodiment, during use, multiple support arms 2 are fixed around the periphery of the main frame 1 of the equipment. Each support arm 2 is rotatably mounted with a track 5 that fits against the inner wall of the pipe. A rotating detection ring 22 is rotatably installed at the port of the main frame 1 of the equipment, and a laser displacement sensor 23 is fixed on the rotating detection ring 22. The laser displacement sensor 23 detects the deformation of the inner wall of the pipe. A main shaft 6 is rotatably installed inside the main frame 1 of the equipment. When the main shaft 6 is driven to rotate clockwise, it will drive the track 5 to rotate on the support arm 2 to drive the main frame 1 of the equipment to move continuously inside the pipe. When the main shaft 6 is driven to rotate counterclockwise, it will drive the rotating detection ring 22 to rotate counterclockwise to drive the laser displacement sensor. The device 23 rotates circumferentially along the rotating detection ring 22 to detect deformation of the inner wall of the pipeline. During detection, when the main shaft 6 rotates clockwise, it drives the track 5 to rotate and continuously travel along the inner wall of the pipeline to the area to be detected. When the main shaft 6 rotates counterclockwise, it drives the rotating detection ring 22 to rotate and drive the laser displacement sensor 23 to perform a 360° rotational scan. At the same time, the track 5 remains stationary. This mechanism ensures that the equipment can be fixed in a specific position inside the pipeline for displacement-free detection, which can eliminate the positioning detection error caused by continuous movement of the equipment. At the same time, the rotation of the laser displacement sensor 23 can be used to re-inspect the fixed position and perform a 360° all-round scan, resulting in a wide detection coverage and high detection accuracy.

[0030] As a further embodiment of the present invention, a drive motor 7 is fixedly installed inside the main frame 1 of the equipment, and the output end of the drive motor 7 is connected to the main shaft 6 through a coupling to drive the main shaft 6 to rotate.

[0031] In this embodiment, the drive motor 7 is electrically connected to an external power source via a wire. The drive motor 7 is fixed to the axial center position of the main frame 1 of the equipment via a flange. Starting the drive motor 7 can drive the main shaft 6 to rotate forward or in reverse.

[0032] As a further embodiment of the present invention, two rotating shafts 3 are rotatably arranged on the support arm 2, and a transmission wheel 4 is fixed on the rotating shaft 3. The track 5 is sleeved on the transmission wheel 4 and cooperates with the transmission wheel 4 for transmission.

[0033] In this embodiment, multiple support arms 2 are circumferentially distributed at equal angles on the outer periphery of the main frame 1 of the equipment. Each support arm 2 adopts a U-shaped fork structure at both ends. The rotating shaft 3 is rotatably mounted on the U-shaped fork through a sealed bearing. The inner wall of the track 5 is fixed with uniformly spaced first teeth, and the outer wall of the transmission wheel 4 is fixed with equally spaced second teeth. The first teeth and the second teeth mesh with each other. When the rotating shaft 3 rotates, it will drive the transmission wheel 4 to rotate. The transmission wheel 4 meshes with the track 5 to drive the track 5 to rotate.

[0034] As a further embodiment of the present invention, the first linkage structure includes a rotating drum 8 rotatably disposed inside the main frame 1 of the equipment. The rotating drum 8 is driven by a first ratchet mechanism. When the main shaft 6 rotates clockwise, it will drive the rotating drum 8 to rotate clockwise. When the main shaft 6 rotates counterclockwise, the rotating drum 8 will not rotate. A first transmission shaft 9 and a second transmission shaft 12 are rotatably disposed on the main frame 1 of the equipment. The first transmission shaft 9 is driven by a first bevel gear mechanism. When the rotating drum 8 rotates, it will drive the first transmission shaft 9 to rotate synchronously. The first transmission shaft 9 is driven by a second bevel gear mechanism. When the first transmission shaft 9 rotates, it will drive the second transmission shaft 12 to rotate synchronously. The second transmission shaft 12 is driven by a first pulley mechanism. When the second transmission shaft 12 rotates, it will drive the rotating shaft 3 to rotate synchronously.

[0035] In this embodiment, when the main shaft 6 rotates clockwise, the rotating drum 8 will rotate clockwise due to the transmission between the rotating drum 8 and the main shaft 6 via the first ratchet mechanism. When the main shaft 6 rotates counterclockwise, the rotating drum 8 will not rotate. When the rotating drum 8 rotates, it will drive the first transmission shaft 9 to rotate synchronously. When the first transmission shaft 9 rotates, it will drive the second transmission shaft 12 to rotate synchronously. When the second transmission shaft 12 rotates, it will drive the rotating shaft 3 to rotate synchronously. The rotation of the rotating shaft 3 will drive the track 5 to rotate, thereby driving the main frame 1 of the equipment to move along the inner wall of the pipe. Since the rotating drum 8 will not rotate when the main shaft 6 rotates counterclockwise, the track 5 will not rotate either, and the main frame 1 of the equipment will remain stationary.

[0036] As a further embodiment of the present invention, the first ratchet mechanism includes a first ratchet internal gear ring 18 fixed to the inner wall of the rotating drum 8 and a first drive disk 19 fixed to the main shaft 6. A first pawl 20 is hinged to the first drive disk 19, and a first spring limiting piece 21 is fixed to the first drive disk 19 and movably attached to one side wall of the first pawl 20. The first pawl 20 is movably engaged with the gear teeth on the inner edge of the first ratchet internal gear ring 18.

[0037] In this embodiment, the first spring limiting plate 21 is pre-compressed and deformed, so that the first pawl 20 always elastically fits the tooth surface of the first ratchet inner gear ring 18. When the first drive disk 19 rotates clockwise, it drives the first pawl 20 to rotate clockwise. When the first pawl 20 rotates, it will drive the first ratchet inner gear ring 18 to rotate synchronously, thereby driving the rotating drum 8 to rotate synchronously. When the first drive disk 19 rotates counterclockwise, the first pawl 20 fits the tooth surface of the first ratchet inner gear ring 18. The rotation of the first pawl 20 will squeeze and deform the first spring limiting plate 21, and will not drive the first ratchet inner gear ring 18 to rotate, thus the rotating drum 8 will not rotate. The surface of the first pawl 20 is treated with tungsten carbide coating to increase wear resistance.

[0038] As a further embodiment of the present invention, the first bevel gear mechanism includes a first bevel gear ring 10 fixed on the rotating drum 8 and a first bevel gear 11 fixed at one end of the first transmission shaft 9, wherein the first bevel gear ring 10 meshes with the first bevel gear 11.

[0039] In this embodiment, when the rotating drum 8 rotates, it will drive the first bevel gear ring 10 to rotate. The first bevel gear ring 10 meshes with the first bevel gear 11. When the first bevel gear ring 10 rotates, it will drive the first bevel gear 11 to rotate, thereby driving the first transmission shaft 9 to rotate.

[0040] As a further embodiment of the present invention, the second bevel gear mechanism includes a second bevel gear 14 fixed at the other end of the first transmission shaft 9 and a second bevel gear ring 13 fixed on the second transmission shaft 12, wherein the second bevel gear ring 13 meshes with the second bevel gear 14.

[0041] In this embodiment, when the first drive shaft 9 rotates, it drives the second bevel gear 14 to rotate. The second bevel gear ring 13 meshes with the second bevel gear 14 to drive the second bevel gear ring 13 to rotate, which in turn drives the second drive shaft 12 to rotate.

[0042] As a further embodiment of the present invention, the first pulley mechanism includes a first pulley 15 fixed on a second transmission shaft 12 and a second pulley 16 fixed on a rotating shaft 3, with the first pulley 15 and the second pulley 16 being driven by a belt 17.

[0043] In this embodiment, when the second drive shaft 12 rotates, it drives the first pulley 15 to rotate. The first pulley 15 and the second pulley 16 are driven by a belt 17. When the first pulley 15 rotates, it drives the second pulley 16 to rotate. When the second pulley 16 rotates, it drives the rotating shaft 3 to rotate.

[0044] As a further embodiment of the present invention, the second linkage structure includes a second ratchet internal gear ring 24 fixed on the inner wall of the rotating detection ring 22 and a second drive disk 25 fixed on the main shaft 6. A second pawl 26 is hinged on the second drive disk 25, and a second spring limiting piece 27 is fixed on the second drive disk 25 and movably attached to one side wall of the second pawl 26. The second pawl 26 is movably engaged with the gear teeth on the inner edge of the second ratchet internal gear ring 24.

[0045] In this embodiment, the second spring limiting plate 27 is pre-compressed and deformed, so that the second pawl 26 always elastically fits against the tooth surface of the second ratchet inner gear ring 24. When the main shaft 6 rotates clockwise, it drives the second drive disk 25 to rotate clockwise. When the second drive disk 25 rotates, it drives the second pawl 26 to rotate. The second pawl 26 fits against the tooth surface of the second ratchet inner gear ring 24. The rotation of the second pawl 26 will compress and deform the second spring limiting plate 27, and will not drive the second ratchet inner gear ring 24 to rotate. Consequently, the rotating detection ring 22 will not rotate. The main shaft 6 rotates counterclockwise. When the clock hand rotates, it drives the second drive disk 25 to rotate counterclockwise, which in turn drives the second pawl 26 to rotate counterclockwise. When the second pawl 26 rotates, it is engaged with the inner gear ring 24 of the second ratchet, which drives the inner gear ring 24 to rotate synchronously, thereby driving the rotating detection ring 22 to rotate synchronously. The surface of the second pawl 26 is treated with tungsten carbide coating to increase wear resistance. In addition, a sealing end cap 28 is fixedly installed on the rotating detection ring 22 by bolts to prevent external moisture and dust from entering the inside of the rotating detection ring 22 and corroding the components.

[0046] The working principle of this invention is as follows: The drive motor 7 is started to drive the main shaft 6 to rotate clockwise. When the main shaft 6 rotates clockwise, it drives the track 5 to rotate on the support arm 2, thereby driving the main frame 1 of the equipment to move continuously inside the pipeline. When the drive motor 7 is started to drive the main shaft 6 to rotate counterclockwise, it drives the rotating detection ring 22 to rotate counterclockwise, thereby driving the laser displacement sensor 23 to rotate circumferentially along the rotating detection ring 22 to detect deformation of the inner wall of the pipeline. Thus, during detection, when the main shaft 6 rotates clockwise, it drives the track 5 to rotate and continuously travel along the inner wall of the pipeline to the area to be detected. When the main shaft 6 is driven counterclockwise again, it drives the rotating detection ring 22 to rotate, thereby driving the laser displacement sensor 23 to perform a 360° rotational scan. At the same time, the track 5 remains stationary. This mechanism ensures that the equipment can be fixed in a specific position inside the pipeline for displacement-free detection. At the same time, the rotation of the laser displacement sensor 23 allows for re-inspection of the fixed position and 360° all-round scanning, resulting in a wide detection coverage and high detection accuracy.

[0047] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
