Description

Technical Field

[0001] This invention relates to the field of pipeline anti-crystallization technology, and in particular to an ultrasonic resonance device for treating crystallization in transverse drainage pipes of highway tunnels. Background Technology

[0002] In recent years, with the rapid development of highway transportation, tunnel engineering has become an important means of overcoming terrain obstacles, adverse geological conditions, and severe weather, and is widely used in highway construction. However, due to various factors such as tunnel geology, design and construction technology, and operation and management, tunnel defects are becoming increasingly prominent. Some tunnels develop defects and require treatment shortly after opening to traffic, and have undergone multiple treatments in a short period. These treatments are difficult and costly, making it difficult to maintain normal tunnel performance, reducing tunnel durability, endangering traffic safety, and having a significant impact on society, posing enormous challenges to tunnel builders and managers.

[0003] Highway tunnel drainage pipes are pipes embedded in concrete that serve to guide and drain water. However, these pipes inevitably experience varying degrees of blockage. Several factors contribute to this blockage, such as the accumulation and sedimentation caused by unremoved silt, or the formation of crystals and precipitates from calcium ions or impurities in groundwater that adhere to the pipe's inner wall. Blockage in highway tunnel drainage pipes prevents timely drainage of groundwater, posing a significant threat to the tunnel's structural safety. Transverse drainage pipes are also crucial drainage systems in highway tunnels. They are perpendicular to the length of the tunnel and to the central drainage ditch, allowing water to flow into and out of the central ditch. In existing technologies, ultrasonic generators are generally used to dredge transverse drainage pipes in highway tunnels. Before removing crystals from the transverse drainage pipes, the ultrasonic transducer on the ultrasonic generator needs to be installed on the transverse drainage pipes. However, in actual operation, the ultrasonic transducer cannot be easily installed on the transverse drainage pipes, which not only reduces the efficiency of removing crystals from the transverse drainage pipes, but also wastes the time and energy of the staff. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an ultrasonic resonance device for treating crystallization in transverse drainage pipes of highway tunnels. This addresses the technical problem that in the prior art, ultrasonic generators are generally used to unclog transverse drainage pipes in tunnels. Before removing crystals from the transverse drainage pipes, the ultrasonic transducer on the ultrasonic generator needs to be installed on the transverse drainage pipe. However, in actual operation, the ultrasonic transducer cannot be easily installed on the transverse drainage pipe, which not only reduces the efficiency of crystal removal from the transverse drainage pipe but also wastes the time and effort of the workers.

[0005] To achieve the above-mentioned technical objectives, the present invention provides an ultrasonic resonance device for treating crystallization in transverse drainage pipes of highway tunnels. The device includes a gantry frame, within which an ultrasonic transducer and a distance sensor are installed via a lifting mechanism. The ultrasonic transducer is electrically connected to an ultrasonic generator, and the distance sensor is electrically connected to a controller. The distance sensor is used to detect the distance between the underground transverse drainage pipe and the ultrasonic transducer. The controller is used to receive the signal sent by the distance sensor and control the lifting mechanism to raise and lower, so that the ultrasonic transducer contacts the transverse drainage pipe to remove the crystallization inside the transverse drainage pipe.

[0006] Furthermore, rollers are installed at all four corners of the bottom of the gantry frame.

[0007] Furthermore, cylinders are installed at the four corners of the bottom of the gantry frame, and each cylinder's piston rod is equipped with a pad.

[0008] Furthermore, a handle is installed on the top of the gantry.

[0009] Furthermore, the lifting mechanism includes a lifting plate, a distance sensor installed at the bottom of the lifting plate, a lifting rod installed at the bottom of the lifting plate, an ultrasonic transducer installed at the lower end of the lifting rod, threaded sleeves installed on both sides of the lifting plate, and a transmission screw threadedly connected to each of the two threaded sleeves. The lower ends of the two transmission screws are respectively mounted on two support rods via bearings, and the two support rods are respectively fixedly installed inside the gantry frame. The upper ends of the two transmission screws are respectively mounted on the top of the gantry frame via bearings, and the upper ends of the two transmission screws are also respectively connected to a drive mechanism for driving the two transmission screws to rotate.

[0010] Furthermore, the drive mechanism includes two gears, which are respectively mounted on the upper ends of two transmission screws and are connected by a transmission chain. One of the gears is connected to the output shaft of the motor.

[0011] Furthermore, both ends of the lifting plate are equipped with sliding sleeves, and sliding rods are slidably installed inside the two sliding sleeves. The lower ends of the two sliding rods are fixed to the two support rods respectively, and the upper ends of the two sliding rods are fixedly installed on the top of the gantry frame respectively.

[0012] Furthermore, an elastic seat is installed at the lower end of the lifting rod, and the ultrasonic transducer is installed at the bottom of the elastic seat.

[0013] Furthermore, the elastic seat includes a telescopic sleeve, which is installed at the lower end of the lifting rod. A telescopic rod is provided inside the telescopic sleeve, and the lower end of the telescopic rod extends out of the telescopic sleeve and is fitted with a ball seat. The ball seat and the telescopic sleeve are connected by a first elastic element. The ball seat has a spherical cavity, and a rotating ball is provided inside the spherical cavity. The outer wall of the rotating ball is connected to the upper end of the connecting rod. The bottom of the ball seat has a through hole communicating with the spherical cavity. The lower end of the connecting rod passes through the through hole and is fitted with an installation block. The installation block and the ball seat are connected by a second elastic element. An ultrasonic transducer is installed at the bottom of the installation block.

[0014] Furthermore, both the first and second elastic elements are springs.

[0015] The beneficial effects of this invention include:

[0016] 1. The distance sensor can detect the distance between the underground horizontal drainage pipe and the ultrasonic transducer. The controller can receive the signal sent by the distance sensor and control the lifting mechanism to raise and lower, so that the ultrasonic transducer contacts the horizontal drainage pipe to remove the crystals in the horizontal drainage pipe. There is no need to manually install the ultrasonic transducer on the horizontal drainage pipe before crystal removal, which not only improves the efficiency of crystal removal in the horizontal drainage pipe, but also saves the time and effort of the staff.

[0017] 2. When the ultrasonic resonance device needs to be moved to the location where crystals need to be removed from the horizontal drain pipe, the cylinder can drive the pads to descend so that the pads are supported on the ground, and at the same time, the rollers are disengaged from the ground, which can prevent the ultrasonic resonance device from moving during operation. When the ultrasonic resonance device needs to be moved, the cylinder can drive the pads to rise so that the rollers contact the ground, thus making it easy to move the ultrasonic resonance device.

[0018] 3. The telescopic rod can extend and retract within the telescopic sleeve, allowing adjustment of the height of the ultrasonic transducer. The rotating ball can rotate within the spherical cavity of the ball seat, allowing adjustment of the angle between the ultrasonic transducer and the horizontal plane. Simultaneously, the first and second elastic elements possess certain elastic properties, and their combined action ensures close contact between the ultrasonic transducer and the transverse drainage pipe, improving the crystal removal effect of the transverse drainage pipe.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] This invention provides an ultrasonic resonance device for treating crystallization in transverse drainage pipes of highway tunnels, such as... Figure 1-3 As shown, the system includes a gantry frame 1. An ultrasonic transducer 3 and a distance sensor 4 are installed inside the gantry frame 1 via a lifting mechanism 2. The distance sensor 4 is a high-precision CMOS laser displacement sensor of the LK-G5000 series. The ultrasonic transducer 3 is electrically connected to an ultrasonic generator 5, model KMD-2840. The distance sensor 4 is also electrically connected to a controller 6, model FX1N-40MR-001. The distance sensor 4 is used to detect the distance between the underground horizontal drainage pipe and the ultrasonic transducer 3. The controller 6 receives the signal sent by the distance sensor 4 and controls the lifting mechanism 2 to raise and lower, bringing the ultrasonic transducer 3 into contact with the horizontal drainage pipe to remove crystals inside.

[0027] The distance sensor 4 can detect the distance between the underground horizontal drainage pipe and the ultrasonic transducer 3. The controller 6 can receive the signal sent by the distance sensor 4 and control the lifting mechanism 2 to lift and lower, so that the ultrasonic transducer 3 comes into contact with the horizontal drainage pipe to remove the crystals in the horizontal drainage pipe. There is no need to manually install the ultrasonic transducer 3 on the horizontal drainage pipe before removing the crystals, which not only improves the efficiency of removing crystals from the horizontal drainage pipe, but also saves the time and effort of the staff.

[0028] It should be noted that the gantry frame 1 includes a top plate and two side plates installed on both sides of the bottom of the top plate. The top plate and the two side plates form a U-shaped structure.

[0029] It should be noted that both the ultrasonic generator 5 and the controller 6 are mounted on top of the gantry frame 1.

[0030] Preferably, rollers 11 are installed at each of the four corners of the bottom of the gantry frame 1. The position of the ultrasonic resonance device can be easily moved using the rollers 11.

[0031] It should be noted that roller 11 is a swivel wheel.

[0032] Preferably, cylinders 12 are installed at the four corners of the bottom of the gantry frame 1. Each cylinder 12 is connected to an external air supply device to supply air to it. The cylinder 12 is a CM2B20-150 model. Each cylinder 12 has a foot 13 mounted on its piston rod. When the ultrasonic resonance device needs to be moved to the location where crystals need to be removed from the horizontal drain pipe, the cylinder 12 can lower the foot 13 to support it on the ground, simultaneously disengaging the roller 11 from the ground. This prevents the ultrasonic resonance device from shifting during operation. When the ultrasonic resonance device needs to be moved, the cylinder 12 can raise the foot 12, bringing the roller 11 into contact with the ground, thus facilitating the movement of the ultrasonic resonance device.

[0033] Preferably, a handle 14 is installed on the top of the gantry 1. The ultrasonic resonance device can be easily pushed by the handle 14, thereby further facilitating the movement of the ultrasonic resonance device.

[0034] It should be noted that there are two handles 14, both of which are inverted U-shaped structures, and the two handles 14 are symmetrically installed on both sides of the top of the gantry frame 1.

[0035] Preferably, both handles 14 are fitted with anti-slip sleeves. The anti-slip sleeves can prevent the staff from slipping when they hold the handles 14 to push the ultrasonic resonance device, so as to avoid accidents. At the same time, it can also make the staff feel more comfortable when they hold the handles 14.

[0036] More specifically, the lifting mechanism 2 includes a lifting plate 21, a distance sensor 4 installed at the bottom of the lifting plate 21, a lifting rod 22 installed at the bottom of the lifting plate 21, an ultrasonic transducer 3 installed at the lower end of the lifting rod, threaded sleeves 23 installed on both sides of the lifting plate 21, and transmission screws 24 threadedly connected to the two threaded sleeves 23. The lower ends of the two transmission screws 24 are respectively mounted on two support rods 25 through bearings. The two support rods 25 are respectively fixedly installed in the gantry frame 1. The upper ends of the two transmission screws 24 are respectively mounted on the top of the gantry frame 1 through bearings. The upper ends of the two transmission screws 24 are also respectively connected to a drive mechanism 26 for driving the rotation of the two transmission screws 24. The drive mechanism 26 can drive the two transmission screws 24 to rotate, and the two transmission screws 24 can drive the lifting plate 21 to rise and fall through the two threaded sleeves 23. The lifting plate 21 can drive the lifting rod 22 to rise and fall, thereby driving the ultrasonic transducer 3 to rise and fall. The structure is simple and the design is reasonable.

[0037] In this embodiment, the drive mechanism 26 includes two gears 261, which are respectively mounted on the upper ends of two transmission screws 24. The two gears 261 are connected by a transmission chain 262. One of the gears 261 is connected to the output shaft of a motor 263, which is a Panasonic MSME750W low-inertia motor. The motor 263 can drive one of the gears 261 to rotate, and one of the gears 261 can drive the other gear 261 to rotate via the transmission chain 262, thereby driving the two transmission screws 24 to rotate.

[0038] It should be noted that both gears 261 are installed inside the gearbox, which is mounted on top of the gantry frame 1, and the motor 263 is mounted on top of the gearbox.

[0039] Preferably, both ends of the lifting plate 21 are equipped with sliding sleeves 27, and each sliding sleeve 27 has a sliding rod 28 slidably mounted inside it. The lower ends of the two sliding rods 28 are respectively fixed to two support rods 25, and the upper ends of the two sliding rods 28 are respectively fixed to the top of the gantry frame 1. The sliding sleeves 27 and the sliding rods 28 work together to make the lifting plate 21 rise and fall stably.

[0040] In this embodiment, an elastic seat 29 is installed at the lower end of the lifting rod 22, and the ultrasonic transducer 3 is installed at the bottom of the elastic seat 29. The elastic seat 29 allows the ultrasonic transducer 3 to be in close contact with the transverse drain pipe, which can better remove crystals in the transverse drain pipe.

[0041] More specifically, such as Figure 4-5 The elastic seat 29 shown includes a telescopic sleeve 291, which is installed at the lower end of the lifting rod 22. A telescopic rod 292 is provided inside the telescopic sleeve 291. The lower end of the telescopic rod 292 extends out of the telescopic sleeve 291 and is fitted with a ball seat 293. The ball seat 293 and the telescopic sleeve 291 are connected by a first elastic element 294. The ball seat 293 is provided with a spherical cavity 2931, and a rotating ball 295 is provided inside the spherical cavity 2931. The outer wall of the rotating ball 295 is connected to the upper end of the connecting rod 296. The bottom of the ball seat 293 is provided with a through hole 2932 communicating with the spherical cavity 2931. The lower end of the connecting rod 296 passes through the through hole 2932 and is fitted with a mounting block 297. The mounting block 297 and the ball seat 293 are connected by a second elastic element 298. The ultrasonic transducer 3 is installed at the bottom of the mounting block 297.

[0042] The telescopic rod 292 can extend and retract within the telescopic sleeve 291, allowing adjustment of the height of the ultrasonic transducer 3. The rotating ball 295 can rotate within the spherical cavity 2931 of the ball seat 293, allowing adjustment of the angle between the ultrasonic transducer 3 and the horizontal plane. Meanwhile, the first elastic element 294 and the second elastic element 298 have certain elastic properties, and their combined action allows the ultrasonic transducer 3 to make close contact with the transverse drain pipe, thereby better removing crystals from the transverse drain pipe.

[0043] It should be noted that the diameter of the spherical cavity 2931 is equal to the diameter of the rotating sphere 295.

[0044] It should be noted that the diameter of the through hole 2932 is smaller than the diameter of the spherical cavity 2931, and the diameter of the through hole 2931 is larger than the diameter of the connecting rod 296.

[0045] More specifically, the diameter of the through hole 2932 is 2 to 3 times the diameter of the connecting rod 296.

[0046] In this embodiment, both the first elastic element 294 and the second elastic element 298 are springs.

[0047] For the first elastic element 294 and the second elastic element 298, they only need to have certain elastic properties. Therefore, they are not limited to the form of springs. For example, in some other embodiments, the first elastic element 294 and the second elastic element 298 are both elastic elements with certain elastic properties, such as elastic silicone sleeves or elastic rubber sleeves.

[0048] In this embodiment, a portable power supply is also included for powering the electrical equipment on the ultrasonic resonance device. The portable power supply can power the electrical equipment on the ultrasonic resonance device without the need for an external power source, and can be used for different occasions.

[0049] Specific principle: Before using the ultrasonic resonance device to remove crystals from the transverse drainage pipe, a hole is drilled in the road surface at the location where crystals need to be removed from the transverse drainage pipe inside the highway tunnel, exposing this location underground. When using the ultrasonic resonance device to remove crystals from the transverse drainage pipe, the device is moved to the location where crystals need to be removed. The distance sensor 4 detects the distance between the underground transverse drainage pipe and the ultrasonic transducer 3. The controller 6 receives the signal sent by the distance sensor 4 and controls the motor 263. The motor 263 drives one of the gears 261 to rotate. One gear 261 drives another gear 261 to rotate via the transmission chain 262, thereby driving the two transmission screws 24 to rotate. 4. The lifting plate 21 can be lowered by two threaded sleeves 22. The lifting plate 21 can lower the lifting rod 22, which in turn lowers the ultrasonic transducer 3, bringing it into contact with the transverse drain pipe. The ultrasonic waves emitted by the ultrasonic transducer 3 can cause the transverse drain pipe to vibrate, removing the crystals inside. After the crystals are removed, the motor 263 can drive one of the gears 261 to rotate in the opposite direction. One of the gears 261 can drive the other gear 261 to rotate via the transmission chain 262, which in turn drives the two transmission screws 24 to rotate. The two transmission screws 24 can drive the lifting plate 21 to rise via the two threaded sleeves 22. The lifting plate 21 can then drive the lifting rod 22 to rise, which in turn raises the ultrasonic transducer 3, allowing it to return to its original position.

[0050] The beneficial effects of this invention include: This invention provides an ultrasonic resonance device for treating crystallization in transverse drainage pipes of highway tunnels. The distance sensor 4 can detect the distance between the underground transverse drainage pipe and the ultrasonic transducer 3. The controller 6 can receive the signal sent by the distance sensor 4 and control the lifting mechanism 2 to lift and lower, so that the ultrasonic transducer 3 comes into contact with the transverse drainage pipe to remove the crystals in the transverse drainage pipe. It is not necessary to manually install the ultrasonic transducer 3 in the transverse drainage pipe before removing the crystals, which not only improves the efficiency of removing crystals from the transverse drainage pipe, but also saves the time and effort of the staff.

[0051] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
