Description

Technical Field

[0001] This invention relates to a pipeline detection device, and more particularly to an adjustable underground pipeline detection device. Background Technology

[0002] A pipeline is a device consisting of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Pipelines have a wide range of applications, primarily for water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. However, with prolonged operation, natural aging of equipment, and changes in underground burial and climate, leaks occur frequently, especially in the petrochemical industry. Leaks in these pipelines can cause serious environmental pollution and safety incidents for residents, and also result in significant economic losses for the country. Therefore, it is necessary to establish a pipeline inspection system to monitor underground pipelines.

[0003] Current pipeline detection methods mostly rely on vibratory wave detection vehicles. The vibratory wave receiver is installed under the vehicle, which can only be used to detect the ground by moving the vehicle. This method is not convenient for detecting different angles at a specific location, and it is not conducive to quickly determining the pipeline's direction. After detection, marking is usually done manually by planting flags or applying paint. When planting flags, the flags can usually mark the location of the pipeline, but it is not conducive to determining the pipeline's direction. Manual application is more troublesome, as it requires carrying paint and following the detection vehicle to apply it. When applying paint, the location and direction of the pipeline must be marked based on visual memory after the detection vehicle leaves, which is prone to forgetting and memory errors, resulting in low marking accuracy. Summary of the Invention

The push rod is cylindrical. A first one-way valve is installed at the top of the push rod. The push rod communicates with the outside through a cavity.

[0006] The above technical solution facilitates the adjustment of the angle of the vibration wave receiver, enabling comprehensive land surveying.

[0007] The above technical solutions facilitate the control of paint discharge, land marking, and pipeline routing.

[0008] The above technical solution facilitates the opening and closing of the discharge pipe by installing a block, thereby controlling the discharge of the coating.

[0009] The above technical solution facilitates the cleaning of the bottom of the vibration wave receiver, thereby preventing sand and soil splashed on the ground from adhering to the vibration wave receiver and affecting its operation.

[0010] The above technical solution can be used to inflate the water chamber, thereby increasing the pressure inside the water chamber.

[0011] As a preferred embodiment of the present invention, a plurality of support rods are fixedly connected between the first fixed ring and the second fixed ring, and the plurality of support rods are arranged in a ring matrix.

[0012] The above technical solution increases the firmness between the first fixing ring and the second fixing ring.

[0013] As a preferred embodiment of the present invention, the fixing block has a cross-shaped structure, the vibration wave receiver is disposed on both sides of the fixing block, and the sliding plate has a "T"-shaped structure.

[0014] The above technical solution avoids the paint from spraying onto the vibration wave receiver.

[0015] As a preferred embodiment of the present invention, the air intake assembly includes an air groove, the housing is provided with an air groove at the bottom of the water chamber, the housing is provided with a plurality of air holes for the air groove to communicate with the water chamber, and the air groove is connected to the sliding cavity where the top rod is located through a second one-way valve.

[0016] The above technical solution allows gas to be dispersed into the water chamber, thereby increasing the flow of paint inside the water chamber, reducing paint sedimentation, and ensuring uniform distribution.

[0017] As a preferred embodiment of the present invention, a pressure relief mechanism is connected to the housing, the pressure relief mechanism includes a pressure relief pipe, the pressure relief pipe is installed on the top side of the housing located in the water chamber, the end of the pressure relief pipe opposite to the water chamber is installed on the transmission rod, and the pressure relief pipe is internally connected to the transmission rod.

[0018] The above technical solution facilitates the discharge of gas inside the water chamber, thereby preventing excessive pressure inside the water chamber. It also serves to clean the inside of the transmission rod, using airflow to clear any residual coating inside the transmission rod.

[0019] As a preferred embodiment of the present invention, a pressure relief valve is installed at the pressure relief pipe of the housing, and the water chamber is connected to the pressure relief pipe through the pressure relief valve.

[0020] The above technical solution facilitates the maintenance of a certain pressure inside the water chamber, which allows the coating to be discharged smoothly.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention comprises a vibration wave transmitter, a lever, a transmission rod, a universal joint, and a vibration wave receiver. The transmitter is first positioned at the end of the pipe, emitting vibration waves that extend along the pipe, pushing the housing and causing the receiver to move above the ground. Upon detecting a signal, the housing stops moving, and the lever is moved in the direction of detection. This causes the first rotating ball to rotate. The lever, via the universal joint, drives the transmission rod in the same direction, rotating the second rotating ball. The transmission rod slides on the second rotating ball, thus enabling the receiver on the fixed block at the bottom of the transmission rod to detect the ground. The first and second rotating balls allow for arbitrary angle rotation of the lever and transmission rod. The receiver receives the vibration waves on the ground, and the point of maximum wave peak displayed on the receiver is the detection point directly above the pipe. By changing the angle of the receiver, comprehensive ground detection is achieved, facilitating the location of strong signal sources and determining the pipeline's direction, thereby achieving precise adjustment and improving work efficiency.

[0022] 2. This invention, by setting up an airbag, a closing plug, a rubber stopper, and a cleaning brush, compresses the airbag by pressing the pressing block. The gas pushes the closing plug downward, allowing the paint to enter the transmission rod from the discharge pipe and channel, and then be sprayed from the spray head. This marks the land, facilitating subsequent construction. During spraying, bending the lever along the pipeline direction marks the path on the ground, making it easier for workers to determine. When the gas inside the airbag enters the transmission rod, it pushes the rubber stopper, causing the cleaning brush to sweep across the bottom of the vibration wave receiver, thus cleaning the bottom of the receiver and preventing it from affecting the detection effect.

[0023] 3. This invention, by setting a cam, a push rod, and a pressure relief valve, allows the rotating shaft on the moving wheel to drive the cam to rotate during the movement of the housing, thereby pushing the push rod upward. This forces the air inside the sliding cavity where the push rod is located into the air groove in one direction, and then sprays it into the water chamber through the air hole. The gas is then sprayed out from the bottom of the water chamber, which makes the coating inside the water chamber more uniform. At the same time, it increases the pressure inside the water chamber, making it easier for the coating to be discharged from the discharge pipe. When the air pressure inside the water chamber reaches the threshold of the pressure relief valve, the excess gas inside the water chamber will enter the pressure relief pipe through the pressure relief valve and be sprayed out from the spray head, thereby playing a certain role in unblocking.

[0029] according to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, an adjustable underground pipeline detection device includes a marking mechanism 3 connected to a housing 1. The marking mechanism 3 includes a water chamber 31. The water chamber 31 is located at one end of the housing 1. Both the lever 212 and the transmission rod 216 have cavities inside to facilitate gas flow. The gas pushes the closing plug 37 to work. A discharge pipe 32 connected to the bottom of the water chamber 31 is installed on the housing 1. The end of the discharge pipe 32 away from the water chamber 31 is installed on the transmission rod 216 and connected to the inside of the transmission rod 216. A spray head 33 connected to the bottom of the transmission rod 216 is installed to facilitate spraying paint onto the ground to mark the pipeline route. A control component for controlling the opening and closing of the discharge pipe 32 is connected to the transmission rod 216.

[0030] The control assembly includes a closing plug 37. The closing plug 37 is slidably connected inside the transmission rod 216 at the discharge pipe 32. A first spring 38 is fixedly connected between the closing plug 37 and the transmission rod 216. The closing plug 37 is provided with an "L"-shaped through groove 39. A pressing block 34 is slidably connected to the actuating rod 212. An air bladder 36 is provided between the pressing block 34 and the actuating rod 212. The air bladder 36 communicates with the interior of the actuating rod 212. A connecting pipe 35 is installed on the actuating rod 212 and the transmission rod 216 to facilitate the opening and closing of the discharge pipe 32, thereby facilitating the control of paint discharge.

[0031] A cleaning mechanism 5 is connected to the fixed block 218. The cleaning mechanism 5 includes a slide groove 54. A rubber plug 55 is slidably connected to the fixed block 218 through the slide groove 54. The outer wall of the rubber plug 55 and the inner wall of the slide groove 54 are in close contact.

An air guide pipe 53 communicating with the slide groove 54 is installed on the fixed block 218. The end of the air guide pipe 53 away from the fixed block 218 is installed on the transmission rod 216. The transmission rod 216 is provided with a connecting groove 58 for communicating between the air guide pipe 53 and the inside of the transmission rod 216, so as to facilitate the control of the cleaning brush 52 to clean the vibration wave receiver 23.

[0032] The fixing block 218 has a cross-shaped structure, the vibration wave receiver 23 is located on both sides of the fixing block 218, and the sliding plate 51 has a "T" shaped structure, so that the cleaning brush 52 can not reach the bottom of the vibration wave receiver 23 and the vibration wave receiver 23 will not be sprayed with paint.

[0033] according to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an adjustable underground pipeline detection device includes a pressurizing mechanism 4 connected to a housing 1. The pressurizing mechanism 4 includes a cam 41, which is fixedly connected to the rotating shaft of a moving wheel 24. A push rod 42 is slidably connected to the housing 1 at the cam 41. The bottom end of the push rod 42 abuts against the edge of the cam 41. A second spring 44 abuts between the push rod 42 and the housing 1. The push rod 42 is cylindrical, and a first one-way valve 43 is installed at the top of the push rod 42. The push rod 42 is connected to the outside through a cavity. A second one-way valve 45 is installed at the top of the sliding cavity of the push rod 42 in the housing 1. An air intake assembly is provided at the top of the housing 1 at the water chamber 31. The connection end of the second one-way valve 45 is connected to the water chamber 31 through the air intake assembly, which facilitates air injection into the water chamber 31, thereby increasing the pressure inside the water chamber 31.

[0034] The air intake assembly includes an air groove 46. The housing 1 is provided with an air groove 46 at the bottom of the water chamber 31. The housing 1 is provided with a plurality of air holes 47 for the air groove 46 to communicate with the water chamber 31. The air groove 46 is connected to the sliding cavity where the top rod 42 is located through the second one-way valve 45. The air increases the flow of the coating inside the water chamber 31, thereby preventing sedimentation.

[0035] A pressure relief mechanism 6 is connected to the housing 1. The pressure relief mechanism 6 includes a pressure relief pipe 62. The pressure relief pipe 62 is installed on the top side of the housing 1 located in the water chamber 31. The end of the pressure relief pipe 62 away from the water chamber 31 is installed on the transmission rod 216. The pressure relief pipe 62 is connected to the inside of the transmission rod 216, so as to facilitate the discharge of excess gas into the transmission rod 216, thereby facilitating the cleaning of the coating inside the transmission rod 216.

[0036] The housing 1 is equipped with a pressure relief valve 61 at the pressure relief pipe 62. The water chamber 31 is connected to the pressure relief pipe 62 through the pressure relief valve 61, which facilitates the control of the pressure inside the water chamber 31 and retains a certain pressure of gas, thereby facilitating the discharge of the coating.

[0037] In practical use, the housing 1 is equipped with a cover. After opening the cover, paint is injected into the water chamber 31 of the housing 1. The cover is then tightened to seal the housing. When pipeline detection is required on the ground, the vibration wave transmitter 25 is first placed at the end of the pipeline. The vibration wave transmitter 25 emits vibration waves, which extend along the pipeline, pushing the housing 1. This movement is achieved through the casters 24 and swivel casters 22, thereby causing the vibration wave receiver 23 to move above the ground. When a signal is detected, the movement of the housing 1 can be stopped, and the lever 212 can be turned in the direction of detection. This causes the first rotating ball 214 to rotate. The lever 212, through the swivel shaft 215, drives the transmission rod 216 to move in the same direction, thus driving the second rotating ball 214 to rotate. The rotating ball 219 rotates, and the transmission rod 216 slides on the second rotating ball 219, thereby driving the vibration wave receiver 23 on the fixed block 218 at the bottom of the transmission rod 216 to detect the ground. The first rotating ball 214 and the second rotating ball 219 allow the lever 212 and transmission rod 216 to rotate at any angle. The vibration wave receiver 23 receives vibration waves on the ground. The point where the peak of the wave displayed on the vibration wave receiver 23 is the detection point directly above the pipeline. By changing the angle of the vibration wave receiver 23, the purpose of comprehensive ground detection can be achieved, facilitating the location of strong signal sources and determining the pipeline's direction, thus achieving precise adjustment and improving work efficiency; determining the pipeline... After the line is positioned and aligned, press the pressing block 34 to compress the airbag 36, causing the gas inside the airbag 36 to enter the lever 212 and then through the connecting pipe 35 into the transmission rod 216. This pushes the closing plug 37 downward, stretching the first spring 38. The closing plug 37 closes the discharge pipe 32. When the closing plug 37 moves downward, the discharge pipe 32 connects to the transmission rod 216 through the through groove 39. A certain air pressure is injected into the housing 1 by the top rod 42, facilitating the paint to enter the transmission rod 216 from the discharge pipe 32 and through groove 39, and then be sprayed out from the spray head 33. This marks the land for later construction. During spraying... By bending the lever 212 along the pipeline direction, the path can be drawn on the ground, making it easier for staff to determine. When the gas inside the airbag 36 enters the transmission rod 216, some of the gas enters the slide groove 54 through the air guide tube 53, thereby pushing the rubber plug 55 to move. This, in turn, pushes the slide plate 51 to move through the connecting rod 56. The third spring 57 will be stretched, thereby driving the cleaning brush 52 to sweep across the bottom of the vibration wave receiver 23, making it easier to clean the bottom of the vibration wave receiver 23 and avoid affecting the detection effect. When the pressing block 34 is released, the third spring 57 contracts, allowing gas to enter the airbag 36, which inflates the airbag 36. The pressing block 34 slides, making it easy to work again.During the movement of the housing 1, the moving wheel 24 rotates, thereby driving the cam 41 to rotate via the shaft on the moving wheel 24. This pushes the push rod 42 upward, compressing the second spring 44. When the push rod 42 moves upward, the first one-way valve 43 at the top of the push rod 42 is closed, thus forcing the air inside the slide cavity where the push rod 42 is located into the air groove 46 through the second one-way valve 45, and spraying it into the water chamber 31 through the air hole 47. When the thinner end of the cam 41 moves to the push rod 42, the second spring 44 pushes the push rod 42 downward, and external air enters the slide cavity of the push rod 42 through the first one-way valve 43, thereby achieving the purpose of continuous air pumping. Gas is ejected from the bottom of water chamber 31, which makes the coating inside water chamber 31 more uniform and increases the pressure inside water chamber 31, facilitating the discharge of coating from discharge pipe 32. When the air pressure inside water chamber 31 reaches the threshold of pressure relief valve 61, excess gas inside water chamber 31 will enter pressure relief pipe 62 through pressure relief valve 61, and then enter the transmission rod 216. During the movement of housing 1, pressing block 34 is not pressed, closing plug 37 is in place, blocking discharge pipe 32. Pressure relief pipe 62 is connected to transmission rod 216 through through groove 39, and gas will enter transmission rod 216 from pressure relief pipe 62 and be sprayed out from spray head 33, thus playing a certain role in unblocking.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
