Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a municipal pipeline leakage detection device. Background Technology

[0002] Municipal pipeline leakage detection devices can accurately collect leakage characteristic signals of different media pipelines by using technologies such as acoustic detection, pressure detection, and ultrasonic detection to address leakage problems in the three core municipal pipeline networks of water supply, gas supply, and heating. This avoids the problems of low efficiency and difficulty in detecting hidden leaks in traditional manual inspections.

[0003] In the prior art, a pipeline leakage detection device with patent publication number CN222392705U includes a base frame, a servo motor, a display control mechanism, a detection probe, and a dual-head servo motor. A bracket is fixedly connected to the middle of the upper surface of the base frame, and a servo motor is fixedly installed on the upper surface of the base frame on the side of the bracket. The display control mechanism is fixedly installed at the upper end of the bracket. A positioning frame is fixedly connected to the end face of the base, and a detection probe is fixedly installed at the lower end of the positioning frame.

[0004] During use, when controlling the raising and lowering of the detection probe, the detection end of the probe is difficult to adjust in pitch with the raising and lowering adjustment. As a result, when the detection probe is moved to the side or below the pipeline, it is difficult to align with the pipeline to be detected. Consequently, the signal collected by the detection probe is greatly attenuated because the detection end deviates from the leakage characteristic source. Ultimately, some hidden leaks miss the best time for repair, forming a blind spot of hidden leakage. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a municipal pipeline leakage detection device, which can effectively solve the problem that the detection end of the detection probe is difficult to adjust in pitch with the lifting adjustment in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a municipal pipeline leakage detection device, including a detection device body, a mobile trolley, a detection probe disposed above the mobile trolley, a fixed column fixedly connected to the top of the mobile trolley, and a display screen fixedly installed on the top of the fixed column and used in conjunction with the detection probe.

[0008] The auxiliary mechanism includes a lifting mechanism for controlling the height adjustment of the detection probe, a calibration component that can automatically adjust the pitch during the lifting and lowering of the detection probe, and a fitting component for assisting the detection probe in aligning with the surface of the pipe to be inspected.

[0009] The lifting mechanism is located above the detection probe, the calibration component is located outside the calibration component, and the bonding component is located between the detection probe and the calibration component;

[0010] The lifting mechanism includes a motor adapted to be installed on the outside of the fixed column, a threaded rod fixedly connected to the output end of the motor via a coupling, an internal threaded block threaded to the outer surface of the threaded rod, and a slider slidably sleeved on the outer surface of the fixed column and used in conjunction with the internal threaded block.

[0011] Furthermore, the outer end face of the threaded rod is fixedly mounted on the top of the mobile trolley via a bearing, and the internal threaded block and the slider are fixedly connected.

[0012] Furthermore, the calibration assembly includes a fixed plate fixedly connected to the top of the mobile trolley, a guide groove penetrating the surface of the threaded rod, and a force-bearing wheel movably connected to the inner wall of the guide groove.

[0013] Furthermore, the calibration assembly also includes a transmission block fixedly mounted on the outer end face of the force-bearing wheel via a bearing, a rotating rod fixedly connected to the inner surface of the other end of the transmission block, and a mounting block fixedly sleeved on the through end of the rotating rod.

[0014] Furthermore, a rotating bearing sleeve is installed at the connection between the rotating rod and the slider;

[0015] When the slider moves vertically along the surface of the display screen, it can drive the force-receiving wheel to slide along the inner wall of the guide groove through the rotating rod and the transmission block. Then, the force-receiving wheel is squeezed by the inner wall contour of the guide groove, so that the force-receiving wheel drives the rotating rod to rotate through the transmission block. Finally, the rotating rod drives the mounting block to flip during the lifting and lowering of the slider.

[0016] Furthermore, the bonding assembly includes a fixing rod fixedly connected to the bottom of the mounting block, a bearing bead integrally formed on the outer end face of the fixing rod, and a sleeve movably connected to the outer surface of the bearing bead for supporting the detection probe.

[0017] Furthermore, the bonding assembly also includes a plurality of force-bearing rods fixedly connected to the sleeve and used for bonding with the tube wall, and a spring sleeved on the outside of the fixed rod and used for controlling the reset of the sleeve.

[0018] Furthermore, the detection probe and the force-bearing rod are parallel, and the two ends of the spring are fixedly connected to the mounting block and the sleeve, respectively;

[0019] When the force-bearing rod contacts the pipe wall, it can push the sleeve to rotate around the bearing bead through the reaction force of the pipe wall until all the force-bearing rods are in contact with the pipe wall, so as to ensure that the detection direction of the detection probe is aligned with the pipe wall.

[0020] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0021] This utility model, by setting up an auxiliary mechanism, can not only automatically control the pitch adjustment of the detection probe when controlling the probe to rise and fall for detection, thus avoiding the attenuation of the detection probe's collected signal due to deviation from the leakage characteristic source, but also automatically control the detection probe to make fine-tuning angles when the control rod contacts the pipe wall, further ensuring that the detection probe is accurately aligned with the pipe wall. This achieves the effect of enabling maintenance personnel to effectively judge pipeline leakage while reducing safety risks. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example: A municipal pipeline leakage detection device, as shown in the attached document. Figure 1 -Appendix Figure 5 ,include,

[0032] The detection device body 100 includes a mobile trolley 110, a detection probe 120 disposed above the mobile trolley 110, a fixed column 130 fixedly connected to the top of the mobile trolley 110, and a display screen 140 fixedly installed on the top of the fixed column 130 and used in conjunction with the detection probe 120.

[0033] It should be noted that the mobile trolley 110 can move synchronously along the municipal pipeline network, driving the detection probe 120, the fixed column 130, and the display screen 140 to meet the detection needs of long-distance pipeline networks. The fixed column 130 is used to provide vertical support for the display screen 140. The display screen 140 is used to detect the leakage signal collected by the detection probe 120 and convert the signal into intuitive waveforms, leakage probability, and other information for maintenance personnel to judge the leakage situation in real time. The detection probe 120 can use ultrasonic detection to penetrate the pipe wall to identify internal damage and collect leakage characteristic signals. Finally, the signal is displayed on the display screen 140 after transmission.

[0034] The auxiliary mechanism 200 includes a lifting mechanism 210 for controlling the height adjustment of the detection probe 120, a calibration component 220 that can automatically adjust the pitch of the detection probe 120 during the lifting process, and a bonding component 230 for assisting the detection probe 120 in aligning with the surface of the pipe to be inspected.

[0035] The lifting mechanism 210 is located above the detection probe 120, the calibration component 220 is located outside the calibration component 220, and the bonding component 230 is located between the detection probe 120 and the calibration component 220.

[0036] The lifting mechanism 210 includes a motor 211 adapted to be installed on the outside of the fixed column 130, a threaded rod 212 fixedly connected to the output end of the motor 211 via a coupling, an internal threaded block 213 threaded to the outer surface of the threaded rod 212, and a slider 214 slidably sleeved on the outer surface of the fixed column 130 and used in conjunction with the internal threaded block 213.

[0037] It should be explained that after the motor 211 is started, it can drive the threaded rod 212 to rotate, so that the threaded rod 212 drives the internal threaded block 213 and the slider 214 to slide vertically along the surface of the fixed column 130.

[0038] Specifically, the outer end face of the threaded rod 212 is fixedly mounted on the top of the moving trolley 110 by a bearing, and the internal threaded block 213 and the slider 214 are fixedly connected.

[0039] Furthermore, the calibration assembly 220 includes a fixed plate 221 fixedly connected to the top of the mobile trolley 110, a guide groove 222 penetrating the surface of the threaded rod 212, and a force-bearing wheel 223 movably connected to the inner wall of the guide groove 222.

[0040] Preferably, the calibration assembly 220 also includes a transmission block 224 fixedly mounted on the outer end face of the force-bearing wheel 223 via a bearing, a rotating rod 225 fixedly connected to the inner surface of the other end of the transmission block 224, and a mounting block 226 fixedly sleeved on the through end of the rotating rod 225.

[0041] It should also be noted that the fixing plate 221 is used to provide a stable mounting base for the calibration component 220. The inner wall of the guide groove 222 has a sloping profile with varying heights. When the slider 214 drives the force wheel 223 to move down, the force wheel 223 slides along the inner wall of the guide groove 222. At this time, the guide groove 222 squeezes the force wheel 223 through the inner wall, so that the force wheel 223 drives the rotating rod 225 through the transmission block 224. Then the rotating rod 225 drives the mounting block 226 to flip upward. When the slider 214 rises, it drives the mounting block 226 to flip downward. The flipping of the mounting block 226 will directly drive the detection probe 120 to adjust its pitch so that it is aligned with the center of the pipe surface.

[0042] It should be noted that a rotating bearing sleeve is installed at the connection between the rotating rod 225 and the slider 214;

[0043] When the slider 214 moves vertically along the surface of the display screen 140, it can drive the force wheel 223 to slide along the inner wall of the guide groove 222 through the rotating rod 225 and the transmission block 224. Then, the force wheel 223 is squeezed by the inner wall contour of the guide groove 222, so that the force wheel 223 drives the rotating rod 225 to rotate through the transmission block 224. Finally, the rotating rod 225 drives the mounting block 226 to flip during the lifting and lowering process of the slider 214.

[0044] Furthermore, the fitting assembly 230 includes a fixing rod 231 fixedly connected to the bottom of the mounting block 226, a bearing bead 232 integrally formed on the outer end face of the fixing rod 231, and a sleeve 233 movably connected to the outer surface of the bearing bead 232 and used to support the detection probe 120.

[0045] Specifically, the bonding assembly 230 also includes a plurality of force-bearing rods 234 fixedly connected to the sleeve 233 for bonding with the tube wall, and a spring 235 sleeved on the outside of the fixing rod 231 for controlling the reset of the sleeve 233.

[0046] It should be explained that the cooperation between the fixing rod 231 and the bearing bead 232 provides a rotational support point for the sleeve 233. When the force-bearing rod 234 contacts the pipe wall, the reaction force of the pipe wall will push the sleeve 233 to rotate around the bearing bead 232 until all the force-bearing rods 234 are in contact with the pipe wall. At this time, the sleeve 233 drives the detection probe 120 to adjust the angle synchronously to ensure that the detection end is accurately aligned with the pipe wall. After the detection is completed, when all the force-bearing rods 234 have moved to the point where they are no longer in contact with the pipe wall, the reaction force of the spring 235 pulls the sleeve 233 back to its original position for the next detection.

[0047] Preferably, the detection probe 120 and the force-bearing rod 234 are parallel, and the two ends of the spring 235 are fixedly connected to the mounting block 226 and the sleeve 233 respectively;

[0048] When the force-bearing rod 234 contacts the pipe wall, it can push the sleeve 233 to rotate around the bearing bead 232 through the reaction of the pipe wall until all the force-bearing rods 234 are in contact with the pipe wall, so as to ensure that the detection direction of the detection probe 120 is aligned with the pipe wall.

[0049] When using,

[0050] Push the mobile trolley 110 to the side of the municipal pipeline to be inspected, and control the mobile trolley 110 to move each component along the pipeline to adapt to long-distance inspection operations;

[0051] Then, the motor 211 is started to drive the threaded rod 212 to rotate, and the threaded rod 212 drives the internal thread block 213 and the slider 214 to be fixed and slide vertically along the surface of the fixed column 130, thereby driving the calibration component 220, the bonding component 230 and the detection probe 120 to rise and fall synchronously.

[0052] When the slider 214 moves: the rotating rod 225 and the transmission block 224 drive the force wheel 223 to slide along the guide groove 222 on the surface of the threaded rod 212. The guide groove 222 squeezes the force wheel 223 through its inner wall, causing the force wheel 223 to drive the rotating rod 225 to rotate through the transmission block 224. Then the rotating rod 225 drives the fixed mounting block 226 to flip. Thus, through the cooperation of the mounting block 226, the fixed rod 231, the bearing ball 232 and the sleeve 233, the detection probe 120 is driven to automatically adjust its pitch during the lifting and lowering process.

[0053] When the moving trolley 110 drives the force rod 234 to contact the pipe wall: the reaction force of the pipe wall pushes the force rod 234 to drive the sleeve 233 to rotate around the bearing bead 232 until all the force rods 234 are in contact with the pipe wall, ensuring that the detection probe 120 is aligned with the pipe wall;

[0054] Subsequently, the detection probe 120 collects leakage signals through ultrasonic detection, and the signals are transmitted to the display screen 140 to be converted into waveforms, leakage probability and other information for maintenance personnel to judge.

[0055] After the test is completed, the control motor 211 drives the threaded rod 212 to rotate in the opposite direction, causing the slider 214 to rise, thereby causing the force rod 234 to disengage from the pipe wall. The sleeve 233 is reset under the reaction force of the spring 235, and the test probe 120 is also reset. Then the moving trolley 110 is pushed to the next section of the pipeline to repeat the operation.

[0056] In summary, by setting up the auxiliary mechanism 200, not only can the detection probe 120 be automatically controlled to adjust its pitch when it is raised and lowered for detection, thus preventing the acquisition signal of the detection probe 120 from being attenuated due to deviation from the leakage characteristic source, but it can also automatically control the detection probe 120 to make fine-tuning angle adjustments when the force rod 234 contacts the pipe wall, further ensuring that the detection probe 120 is accurately aligned with the pipe wall. This achieves the effect of enabling maintenance personnel to effectively judge pipeline leakage while reducing safety risks.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
