Description

Technical Field

[0001] The present invention relates to the technical field of gas pipeline detection equipment, and in particular to an integrated device for detecting and pumping water accumulation in a low-pressure gas pipeline. Background Art

[0002] In low-pressure gas pipeline systems, the presence of moisture is a problem that cannot be ignored. This moisture may come from a variety of sources, such as the humid environment when the pipeline is laid, moisture penetration in the soil, condensation of water vapor carried in the gas in the pipeline, etc. Over time, this moisture will gradually accumulate at the bottom of the pipeline and form water accumulation.

[0003] The presence of accumulated water in the pipeline poses a serious threat to the safe operation of the gas system. First, the accumulated water will occupy the effective volume of the pipeline and reduce the gas transmission efficiency. Secondly, the accumulated water may react chemically with certain components in the gas to produce corrosive substances, which will accelerate the corrosion of the inner wall of the pipeline. This corrosion will not only reduce the strength and durability of the pipeline, but may also cause safety accidents such as gas leaks. In addition, the accumulated water may also become a breeding ground for bacteria and pollute the gas quality.

[0004] To address the problem of water accumulation in pipelines, existing detection equipment mostly uses liquid level meters for monitoring. When there is water inside the pipeline, the liquid level meter can detect it in real time and issue an alarm message, prompting the operator to take corresponding measures. However, this detection method has obvious limitations. The liquid level meter can only detect whether there is water inside the pipeline and the water level, but cannot provide information about the corrosion condition of the inner wall of the pipeline.

[0005] In actual operation, when the liquid level meter sounds an alarm, it is usually necessary to manually place a suction hose into the pipe and use a vacuum pump to pump out the water. This manual water pumping method is not only inefficient, but also poses a safety hazard. In addition, since the corrosion of the inner wall of the pipe cannot be directly observed, operators often find it difficult to determine the specific cause and degree of harm of the water accumulation, and thus cannot formulate targeted solutions. Summary of the invention

[0006] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0007] To this end, the purpose of the present invention is to propose an integrated device for detecting and pumping water in a low-pressure gas pipeline.

[0025] Specifically, the present invention has a reasonable structure and not only has the ability to detect water accumulation inside the pipeline, but also can accurately detect the corrosion condition inside the pipeline. This dual detection function enables the operator to quickly grasp the internal condition of the pipeline, accurately determine the cause of water accumulation and its potential hazards, and then formulate targeted solutions. In addition, the device also has the ability to automatically start the pumping device for drainage, which effectively replaces manual operation, significantly improves work efficiency, and enhances the convenience of operation.

[0026] Specifically, the present invention is provided with a frame 1, a water collecting and pumping component 2 and a controller 4, wherein the water collecting and pumping component 2 realizes the automatic collection and intelligent treatment of accumulated water, and the water collecting and pumping component 2 includes a concave pipe 21, a water collecting pipe 22, a water accumulation tank 23 and a pumping mechanism 24, and the concave pipe 21 is respectively connected with the inside of the left pipe 50 and the right pipe 51, so as to construct a smooth accumulated water flow path, and its concave design makes full use of the principle of gravity, so that the accumulated water in the left pipe 50 and the right pipe 51 can naturally flow into the concave pipe 21, so as to realize efficient collection. In order to further improve the classified management of accumulated water, the system is equipped with two sets of water collecting pipes 22 and corresponding water accumulation tanks 23, which are respectively responsible for collecting the accumulated water from the inside of the left pipe 50 and the right pipe 51. This design is not only convenient for independently monitoring the water accumulation in the pipelines on both sides, but also can accurately calculate the flow rate and total amount of liquid per unit time by detecting the total amount of liquid in each water storage tank 23, thereby effectively evaluating the degree of water accumulation in the pipeline and the potential corrosion risk. In addition, the present invention also has an intelligent drainage function. When the liquid in any water storage tank 23 reaches a preset liquid level, the controller 4 will automatically activate the pumping mechanism 24 to perform the drainage operation.

Both are equipped with advanced densitometer 314 and spectrometer 317. Density detection reveals the overall content of corrosion products or impurities in the accumulated liquid, and spectrum detection deeply analyzes the specific chemical composition of these products, thereby indirectly reflecting the corrosion status of the inner wall of the pipeline, especially the type and proportion distribution of corrosion products. The middle detection mechanism 32 is responsible for filtering the accumulated water and weighing the corrosion products. By accurately quantifying the weight of the corrosion products, it is directly related to the total amount of corrosion products, providing an intuitive and reliable method for evaluating the severity of the corrosion of the inner wall of the pipeline. Data support, the rotating detection mechanism 34 innovatively simulates the real corrosion environment inside the pipeline, through the built-in rotatable test block 343 directly contact with the accumulated water, using the ultrasonic detector 345 to detect the rust on the surface of the test block 343. This method can directly observe and evaluate the degree of corrosion of the inner wall of the pipeline, especially the distribution and severity of the rust. The above three detection methods work together to form a comprehensive and multi-level monitoring system for the internal conditions of the pipeline, so that operators can quickly and accurately grasp the actual conditions inside the pipeline, accurately determine the cause of water accumulation and its potential hazards, and then formulate and implement targeted solutions. It is particularly worth mentioning that the drive mechanism 35 equipped in this system not only has a powerful synchronous drive capability,It can simultaneously drive the upper detection mechanism 31, the middle detection mechanism 32, the lower detection mechanism 33 and the rotating detection mechanism 34 to realize the simultaneous operation of density spectrum detection, weighing detection and ultrasonic detection, greatly improving the detection efficiency; moreover, the driving mechanism 35 can also drive the pumping mechanism 24 to realize the automatic drainage function, and only one power source is needed to meet the operation requirements of the entire system, effectively reducing the production cost, simplifying the control system, and enhancing the practicality and use effect.

[0027] In one embodiment of the present invention, Figure 3 As shown, the upper detection mechanism 31 has the same structure as the lower detection mechanism 33. The upper detection mechanism 31 includes a transparent container 311, a water inlet valve 312, a drain valve 313, a densitometer 314, a synchronous shaft 315, a limit guide cylinder 316 and a spectrometer 317. The transparent container 311 is fixedly connected to the surface of the frame 1. The water inlet pipe and the drain pipe surface of the transparent container 311 are respectively provided with a water inlet valve 312 and a drain valve 313. The water inlet valve 312 and the drain valve 313 are respectively connected to the driving mechanism 35. The transparent container 311 is connected to the upper end of the water collecting pipe 22 through the water inlet pipe. The densitometer 314 is vertically slidably connected to the transparent container 31 1, a synchronous shaft 315 is fixedly connected to the top of the densitometer 314, a limiting guide cylinder 316 is fixedly connected to the top of the transparent container 311, one end of the synchronous shaft 315 passes through the top of the transparent container 311 and is slidably connected to the inner wall of the limiting guide cylinder 316, a displacement sensor 3151 is arranged on the surface of one end of the synchronous shaft 315 passing through the top of the transparent container 311, a spectrometer 317 is fixedly connected to the surface of the frame 1 and corresponds to the position of the lower end surface of the transparent container 311, and the displacement sensor 3151 and the spectrometer 317 are respectively connected to the controller 4 through the bus system to realize data transmission and control instruction reception.

[0028] It should be noted that the two groups of transparent containers 311 have the same capacity, the drainage pipes of the two groups of transparent containers 311 are connected to the inside of the water storage tank 23 on the corresponding side through hoses, and the initial positions of the two groups of density meters 314 are the same.

[0029] Specifically, the structures and connection relationship of the upper detection mechanism 31 and the lower detection mechanism 33 are further explained. The upper detection mechanism 31 is used to sample and detect the unfiltered accumulated water inside the upper end of the water collection pipe 22, and the lower detection mechanism 33 is used to sample and detect the filtered accumulated water inside the lower end of the water collection pipe 22. The upper detection mechanism 31 and the lower detection mechanism 33 are respectively provided with a densitometer 314 and a spectrometer 317. The two samples are detected by using the densitometer 314 and the spectrometer 317. The density detection can reveal the overall content of corrosion products or impurities in the accumulated liquid, while the spectral detection can further analyze the specific composition of these products. This method can indirectly reflect the corrosion condition of the inner wall of the pipeline, especially the type and proportion of corrosion products.

[0030] Specifically, when in use, the displacement sensor 3151, the spectrometer 317 and the driving mechanism 35 operate according to instructions. The driving mechanism 35 first drives the drain valve 313 in the upper detection mechanism 31 and the lower detection mechanism 33 to close synchronously, and then drives the water inlet valve 312 in the upper detection mechanism 31 and the lower detection mechanism 33 to open synchronously. After the water inlet valve 312 is opened, the unfiltered accumulated water in the upper end of the water collecting pipe 22 enters the transparent container 311 in the upper detection mechanism 31 through the water inlet pipe, and the filtered accumulated water in the lower end of the water collecting pipe 22 enters the transparent container 311 in the lower detection mechanism 33 through the water inlet pipe. When the unfiltered accumulated water and the filtered accumulated water enter the two groups of transparent containers 311 respectively, due to their different densities, the heights of the two groups of density meters 314 in the transparent container 311 are also different, which synchronously causes the two groups of displacement sensors 3151 to be at different positions inside the limit guide cylinder 316. The controller 4 receives the signals from the displacement sensors. After receiving the data sent by the sensor 3151, its value is compared with the value of the density meter 314, and then the density of the unfiltered accumulated water and the density of the filtered accumulated water are obtained. The density detection can reveal the overall content of corrosion products or impurities in the accumulated liquid. In this process, the two groups of spectrometers 317 respectively detect the liquid inside the lower ends of the two groups of transparent containers 311. The specific components of these products can be further analyzed by the spectrometer 317, so as to obtain the type and proportion of corrosion products. After the detection is completed, the displacement sensor 3151 and the spectrometer 317 are closed according to the instruction, and the driving mechanism 35 is operated again according to the instruction. The operation of the driving mechanism 35 first drives the water inlet valve 312 in the upper detection mechanism 31 and the lower detection mechanism 33 to close, and then drives the drain valve 313 in the upper detection mechanism 31 and the lower detection mechanism 33 to open. After the drain valve 313 is opened, the accumulated water inside the two groups of transparent containers 311 is discharged to the corresponding side of the water storage tank 23 through the hose for collection.

[0031] In one embodiment of the present invention, Figure 1 As shown, a one-way valve 221 is provided on the upper end surface of the water collecting pipe 22 , and the one-way valve 221 is located on one side of the top of the connection between the water inlet pipe of the transparent container 311 and the water collecting pipe 22 .

[0032] It should be noted that the one-way valve 221 described in this embodiment is a one-way valve 221 that can only be used for one-way delivery of liquid.

[0033] Specifically, one of the main functions of the one-way valve 221 is to be able to drain water automatically, which means that when water accumulates inside the water collection pipe 22, the one-way valve 221 can open automatically to allow water to flow out without human intervention. This automatic drainage mechanism greatly improves the efficiency and reliability of the system and reduces potential problems caused by water accumulation, such as pipeline corrosion. During the drainage process, since a one-way valve 221 that only allows one-way delivery of liquid is used, the one-way valve 221 can also achieve water-gas separation. This function allows water to flow through the valve while preventing gas from passing through. The importance of water-gas separation lies in that it prevents harmful gases such as gas from entering the water collection pipe 22, thereby avoiding potential safety risks and equipment damage. Therefore, the one-way valve 221 integrates multiple functions of automatic drainage, water-gas separation and preventing gas from entering the water collection pipe 22. Its effect in practical applications is very significant. It not only improves the overall performance and reliability of the system, but also reduces maintenance costs and safety risks.

[0034] In one embodiment of the present invention, Figure 4 As shown, the middle detection mechanism 32 includes a middle connecting tube 321, a filter bottom cover 322, a discharge port 323, a material receiving tube 324 and a weighing instrument 325. The middle connecting tube 321 is horizontally slidably connected to the surface of the frame 1 and is connected to the driving mechanism 35. The top of the middle connecting tube 321 corresponds to the position of the water collecting pipe 22 and is connected. The filter bottom cover 322 is hingedly fixed to the bottom of the middle connecting tube 321 and is horizontally slidably connected to the surface of the frame 1. The bottom of the filter bottom cover 322 corresponds to the position of the water collecting pipe 22. The filter bottom cover 322 is respectively connected to the middle connecting tube 321 and the inside of the water collecting pipe 22. The discharge port 323 is opened on the surface of the frame 1 and is located on one side of the filter bottom cover 322. The material receiving tube 324 is fixedly connected to the surface of the frame 1 and is connected to the inside of the discharge port 323. The weighing instrument 325 is arranged on the inner bottom wall of the material receiving tube 324. The weighing instrument 325 is connected to the controller 4 through the bus system to realize data transmission and reception of control instructions.

[0035] Specifically, the structure and connection relationship of the middle detection mechanism 32 are further explained. The middle detection mechanism 32 is used to filter the accumulated water and weigh the filtered corrosion products or impurities. The content of the corrosion products is quantified by weight. This method is directly related to the total amount of corrosion products and provides intuitive data for evaluating the severity of corrosion on the inner wall of the pipeline.

[0036] The upper detection mechanism 31 and the lower detection mechanism 33 detect the stagnant water and the filtered stagnant water through the density meter 314 and the spectrometer 317. This method mainly focuses on the proportion and type of corrosion products or impurities. The changes in density and spectral characteristics can indirectly reflect the content and type of corrosion products or impurities in the water, thereby inferring the corrosion condition of the inner wall of the pipeline. The middle detection mechanism 32 directly quantifies the content of the corrosion products or impurities after weighing the filtration. This method pays more attention to the total amount of corrosion products or impurities rather than their type or proportion. Although both methods involve the detection of corrosion products or impurities, they have different emphases. The upper detection mechanism 31 and the lower detection mechanism 33 pay more attention to the analysis of the type and proportion of corrosion products or impurities, while the middle detection mechanism 32 pays more attention to the quantification of the total amount of corrosion products or impurities. Therefore, the two methods are not completely redundant in function, but complement each other and can jointly provide more comprehensive information on the corrosion condition of the inner wall of the pipeline.

[0037] Specifically, when in use, the untreated accumulated water first enters the middle connecting tube 321 through the upper end of the water collecting pipe 22. Once entering the middle connecting tube 321, the accumulated water will be finely filtered by the filter bottom cover 322. In this step, the filter bottom cover 322 plays a key role. It can effectively intercept the corrosion products, impurities and other unnecessary particulate matter in the accumulated water, ensuring that these harmful substances are retained on the surface of the filter bottom cover 322. At the same time, the accumulated water filtered by the filter bottom cover 322 becomes purer, and then flows smoothly into the lower end of the water collecting pipe 22, ensuring the cleanliness of the accumulated water. The clean accumulated water filtered by the filter bottom cover 322 can be directly discharged without further treatment. This feature significantly reduces the pollution to the surrounding environment, because the discharged accumulated water has removed most of the corrosion products, impurities and other harmful substances. At the same time, the clean accumulated water also reduces the potential damage to the pump body 241, because the reduction of impurities and pollutants means that the friction and wear encountered by the pump body 241 during operation will also be reduced accordingly, thereby extending the service life of the pump body 241 and achieving good use effect.

[0038] The above is the filtering process. When it is necessary to discharge and weigh the harmful substances in the middle connecting cylinder 321, the driving mechanism 35 operates according to the command. The driving mechanism 35 drives the middle connecting cylinder 321 and the filter bottom cover 322 to move to the side of the discharge port 323. During the movement, the middle connecting cylinder 321 and the filter bottom cover 322 are staggered with the water collecting pipe 22 and the connection state is disconnected. When the filter bottom cover 322 moves to the position of the discharge port 323, its bottom loses its limit and automatically opens under the action of the gravity of the harmful substances. After the filter bottom cover 322 is opened, the harmful substances in the middle connecting cylinder 321 automatically fall into the receiving cylinder 3 24, the weight is weighed by the weighing instrument 325. After the weighing is completed, the weighing instrument 325 sends the data directly to the controller 4. After receiving the data, the controller 4 issues an instruction for the driving mechanism 35 to operate. The driving mechanism 35 operates according to the instruction. The operation of the driving mechanism 35 drives the middle connecting tube 321 and the filter bottom cover 322 to reset. When the filter bottom cover 322 moves, it is squeezed by the frame 1 and reset to the bottom of the middle connecting tube 321 and is slidably connected to the surface of the frame 1. After the middle connecting tube 321 and the filter bottom cover 322 are reset to the origin, they correspond to the position of the water collecting pipe 22 again and remain connected.

[0039] It is understandable that a vibrator may be provided on the surface of the middle connecting tube 321 to reduce the attachment of harmful substances and accelerate the discharge of harmful substances through vibration.

[0040] In one embodiment of the present invention, Figure 5 As shown, the rotation detection mechanism 34 includes a first worm gear 341, a transmission shaft 342, a test block 343, a mounting ring 344 and an ultrasonic detector 345, the concave pipe 21 includes a left connecting pipe 211 and a right connecting pipe 212, the left connecting pipe 211 and the right connecting pipe 212 are respectively connected to the inside of the left pipe 50 and the right pipe 51, the first worm gear 341 is arranged between the left connecting pipe 211 and the right connecting pipe 212, the two ends of the first worm gear 341 are respectively located inside the left connecting pipe 211 and the right connecting pipe 212, and are rotatably connected to the inner walls of the left connecting pipe 211 and the right connecting pipe 212, the first worm gear 341 is connected to the driving mechanism 35, and the transmission shaft 342 is fixedly connected to the inner wall of the first worm gear 341 The two ends of the transmission shaft 342 respectively penetrate into the left connecting pipe 211 and the right connecting pipe 212, and are fixedly connected with a test block 343. The test block 343 is respectively located on the outside of the connection between the water collecting pipe 22 and the left connecting pipe 211 and the connection between the water collecting pipe 22 and the right connecting pipe 212. The mounting ring sleeve 344 is respectively fixedly connected to the surface of the left connecting pipe 211 and the right connecting pipe 212, and corresponds to the position of the test block 343. The ultrasonic detector 345 is fixedly connected to the surface of the mounting ring sleeve 344, and is connected to the controller 4 through the bus system to realize data transmission and reception of control instructions. One end of the ultrasonic detector 345 respectively penetrates into the left connecting pipe 211 and the right connecting pipe 212.

[0041] It should be noted that, in the initial state, the bottom of the test block 343 described in this embodiment faces downward and contacts the accumulated water inside the pipeline. The surface of the test block 343 will be corroded by the accumulated water.

[0042] Specifically, the structure and connection relationship of the rotating detection mechanism 34 are further explained. The rotating detection mechanism 34 is set to simulate the actual corrosion situation inside the pipeline. By setting a rotatable test block 343 in the pipeline, when the test block 343 comes into contact with the accumulated water inside the pipeline, its surface will be corroded, and then the ultrasonic detector 345 is used to detect whether there is rust on the surface of the test block 343. This method can directly observe the corrosion situation of the inner wall of the pipeline, especially the severity of the rust. The ultrasonic detection method can directly observe the corrosion situation of the inner wall of the pipeline, and the use effect is good.

[0043] Specifically, when in use, the ultrasonic detector 345 and the driving mechanism 35 operate according to instructions. The driving mechanism 35 operates to synchronously drive the first worm gear 341 to rotate. The rotation of the first worm gear 341 synchronously drives the transmission shaft 342 and the two groups of test blocks 343 to rotate. After the test block 343 rotates, its bottom faces upward and corresponds to the position of the ultrasonic detector 345. The ultrasonic detector 345 operates to detect the surface of the test block 343. By detecting the degree of rust on its surface, the corrosion condition of the inner wall of the pipeline is judged, and the use effect is good.

[0044] In one embodiment of the present invention, Figure 6As shown, the driving mechanism 35 includes a dual-axis motor 351, an encoder 352, an upper transmission rod 353, a lower transmission rod 354, a one-way transmission 355, a first bevel gear 356, four groups of worm parts 357, three groups of second worm gears 358, a two-way reciprocating screw rod 359, a driving plate frame 3510, an upper gear rod 3511 and a lower gear rod 3512. The dual-axis motor 351 is fixedly connected to the inner wall of the frame 1, and the encoder 352 is fixedly connected to the surface of the dual-axis motor 351. The dual-axis motor 351 and the encoder 352 are respectively connected to the controller 4 through the bus system to realize data The upper transmission rod 353 and the lower transmission rod 354 are respectively connected to the inner wall of the frame 1 and are located at the top and bottom sides of the dual-axis motor 351. The upper transmission rod 353 and the lower transmission rod 354 are respectively connected to the output end of the dual-axis motor 351 through a one-way transmission 355. The first bevel gear 356 is fixedly connected to the bottom of the lower transmission rod 354 and is connected to the pumping mechanism 24. One end of the upper transmission rod 353 passes through the outside of the frame 1 and is connected to the surface of the frame 1. The four groups of worm gears 357 are integrally formed in sequence along the vertical direction. The upper transmission rod 353 passes through one end surface of the outside of the frame 1, the topmost group of worm parts 357 is located on one side of the first worm wheel 341 and meshes with the first worm wheel 341, the three groups of second worm wheels 358 are rotated in sequence along the vertical direction and connected to the surface of the frame 1, and mesh with the other three groups of worm parts 357, the three groups of second worm wheels 358 correspond to the positions of the upper detection mechanism 31, the middle detection mechanism 32 and the lower detection mechanism 33 respectively, the two-way reciprocating screw rods 359 are fixedly connected to the surfaces of the three groups of second worm wheels 358, and are rotatably connected to the surface of the frame 1, driving the plate frame 351 0 are symmetrically threadedly connected to the surfaces of two sets of bidirectional reciprocating screw rods 359 corresponding to the positions of the upper detection mechanism 31 and the lower detection mechanism 33, and are horizontally slidably connected to the surface of the frame 1, the upper gear rod 3511 and the lower gear rod 3512 are respectively fixedly connected to the surface of the driving plate frame 3510, and are horizontally slidably connected to the inner wall of the frame 1, one end of the upper gear rod 3511 and the lower gear rod 3512 are respectively located at one side of the bottom of the water inlet valve 312 and the drain valve 313, and are meshed and connected, and one end of the middle connecting tube 321 is threadedly connected to the outer surface of the bidirectional reciprocating screw rod 359 corresponding to the position of the middle detection mechanism 32.

[0045] It should be noted that the encoder 352 described in this embodiment is used to detect the number of rotations of the dual-axis motor 351 in real time and send the data to the controller 4. The controller 4 determines the positions of the drive plate frame 3510 and the middle connecting tube 321 based on the number of rotations data.

[0046] Specifically, the structure and connection relationship of the driving mechanism 35 are further explained. The driving mechanism 35 can not only synchronously drive the upper detection mechanism 31, the middle detection mechanism 32, the lower detection mechanism 33 and the rotation detection mechanism 34 to operate, and synchronously realize density spectrum detection, weighing detection and ultrasonic detection, but also drive the pumping mechanism 24 to operate and realize automatic drainage. The one power source design reduces production costs, is easy to control, has strong practicality, and has good use effect.

[0047] Specifically, the dual-axis motor 351 and the encoder 352 operate according to the instructions. The dual-axis motor 351 rotates forward through the one-way transmission 355 to synchronously drive the upper transmission rod 353 to rotate. The upper transmission rod 353 rotates and synchronously drives the four groups of worm parts 357 to rotate. The top group of worm parts 357 rotates and synchronously drives the first worm wheel 341 in the rotation detection mechanism 34 to rotate. The other three groups of worm parts 357 rotate and synchronously drive the three groups of second worm wheels 358 to rotate. The three groups of second worm wheels 358 rotate and synchronously drive the three groups of two-way reciprocating screw rods 359 to rotate. The two-way reciprocating screw rod 359 corresponding to the position of the middle detection mechanism 32 rotates and synchronously drives the middle connecting tube 321 to rotate along the outer surface of the two-way reciprocating screw rod 359 and the surface of the frame 1. The two-way reciprocating screw rod 359 corresponding to the position of the upper detection mechanism 31 and the lower detection mechanism 33 rotates to drive the two sets of driving plate frames 3510 to move synchronously inward or outward along the surface of the frame 1. The two sets of driving plate frames 3510 move synchronously and drive the upper gear rod 3511 and the lower gear rod 3512 to move. The upper gear rod 3511 and the lower gear rod 3512 respectively drive the water inlet valve 312 and the drain valve 313 in the upper detection mechanism 31 and the lower detection mechanism 33 to rotate during the movement to realize the opening and closing operation. The dual-axis motor 351 reverses and synchronously drives the lower transmission rod 354 and the first bevel gear 356 to rotate through the one-way transmission 355. The rotation of the first bevel gear 356 synchronously drives the pumping mechanism 24 to operate.

[0048] In one embodiment of the present invention, Figure 6 As shown, the two sets of one-way transmission devices 355 have opposite transmission directions.

[0049] It should be noted that the one-way transmission 355 described in this embodiment is a ratchet one-way transmission.

[0050] Specifically, the two sets of one-way transmission devices 355 are arranged with opposite transmission directions, ensuring that the dual-axis motor 351 can independently drive the mechanism on either side via the one-way transmission device 355, thereby realizing separate drive. This design not only effectively reduces the purchase cost of the power source, but also greatly improves the flexibility of control, and has both high practicality and excellent use results.

[0051] In one embodiment of the present invention, Figure 7As shown, the pumping mechanism 24 includes a pump body 241, a three-way pipe 242, a solenoid valve 243 and a second bevel gear 244. The pump body 241 is arranged on the inner wall of the frame 1 and is located between the two groups of water storage tanks 23. The water inlet end of the pump body 241 is connected to the water outlet end of the three-way pipe 242, and the water inlet ends of the three-way pipe 242 are respectively connected to the inside of the two groups of water storage tanks 23. The solenoid valve 243 is symmetrically arranged on the surface of the three-way pipe 242, and is respectively connected to the controller 4 through the bus system to realize data transmission and control instruction reception. The drainage end of the pump body 241 passes through the outside of the frame 1, and the second bevel gear 244 is fixedly connected to the power output shaft of the pump body 241 and meshes with the first bevel gear 356.

[0052] Specifically, the structure and connection relationship of the pumping mechanism 24 are further explained. The pumping mechanism 24 can automatically drain water when the water level inside the water tank 23 reaches a set height, and make room in time to collect subsequent accumulated water to ensure efficient operation. This mechanism effectively replaces manual operation, which not only significantly improves work efficiency, but also greatly reduces labor intensity and has a good use effect.

[0053] Specifically, when the liquid level sensor 231 detects that the liquid level inside the water tank 23 reaches the set height, it sends the detection data to the controller 4. After receiving the data, the controller 4 issues an instruction to open the solenoid valve 243 and operate the dual-axis motor 351. The dual-axis motor 351 operates according to the instruction. The dual-axis motor 351 reverses and synchronously drives the lower transmission rod 354 and the first bevel gear 356 to rotate through the one-way transmission 355. The rotation of the first bevel gear 356 synchronously drives the second bevel gear 244 and the power output shaft of the pump body 241 to rotate. The rotation of the power output shaft synchronously drives the impeller inside the pump body 241 to rotate. The rotation of the impeller causes the liquid inside the water tank 23 to enter the pump body 241 through the three-way pipe 242, and then be discharged from the outside of the frame 1 through the drainage end.

[0054] In summary, the embodiment of the present invention is an integrated device for detecting and pumping water in a low-pressure gas pipeline. The present invention not only has the ability to detect water accumulation inside the pipeline, but also can accurately detect the corrosion condition inside the pipeline. This dual detection function enables the operator to quickly grasp the internal condition of the pipeline, accurately determine the cause of water accumulation and its potential hazards, and then formulate targeted solutions. In addition, the device also has the ability to automatically start the pumping device for drainage, which effectively replaces manual operation, significantly improves work efficiency, and enhances the convenience of operation.
