Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a portable leakage detection device. Background Art

[0002] Most of the municipal pipelines in China are buried deep underground. Due to the complex underground conditions, harsh environment, long service life, high leakage rate, and difficulty in detecting leakage, a large amount of water leaks through underground pipelines, causing a huge waste of water resources. At the same time, the leakage of pipelines will also cause water pollution and even cause disasters. The installation and disassembly of existing leakage detection devices are very troublesome. Due to the complex underground ring, the detection process of underground water pipes is easily disturbed by the external environment, and the detection effect is poor. Due to the different water pressures in different pipelines, the existing detection devices cannot detect leaks in pipelines with different pressures, and have poor applicability.

[0003] The patent with application number 202121414129.9 discloses a portable leakage detection device, including a pipeline body, a detection tube equidistantly connected to the top of the pipeline body, and a leakage test cylinder arranged above the detection tube, wherein a control valve is installed at the center of the detection tube, and lifting test rods are slidably inserted on both sides of the top surface of the leakage test cylinder, and an elastic adjustment plate is provided at the inner top of the leakage test cylinder, wherein a piston for driving the lifting test rod to move is inserted at the inner bottom of the leakage test cylinder, and a spring is fixedly connected between the elastic adjustment plate and the piston, and a lifting adjustment assembly is connected to the top of the elastic adjustment plate, and at least two detection tubes are provided, and flanges are fixed at the bottom ends of multiple detection tubes. The portable leakage detection device avoids interference of pipeline leakage detection by external factors, improves the detection effect, and facilitates testing of pipelines with different pressures. In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] In practical applications, two pressure detection structures are used to detect pipeline leakage within a certain length. However, since the pressure detection structure is fixed on the pipeline, it is necessary to install the pressure detection structure at a certain interval of the pipeline, which results in high pipeline installation costs. In addition, since the two pressure detection structures are at a certain distance, the scales of the two pressure detection structures cannot be observed in real time. After the pressure detection structure is disassembled, the elastic force of the spring will cause the scale to reset, resulting in poor practicality of the pressure detection device. Utility Model Content

[0005] The purpose of the utility model is to provide a portable leakage detection device to solve the problem raised in the background technology that the scales of the two pressure detection structures cannot be observed in real time due to the certain distance between the two pressure detection structures, and the elastic force of the spring after disassembling the pressure detection structure will cause the scale to reset, which leads to poor practicality of the pressure detection device.

[0006] In the first aspect, the utility model provides a portable leakage detection device, comprising a conveying pipeline and a mounting tube equidistantly fixed on the outer wall of the conveying pipeline, and also comprising a detection tube detachably fixed to the top end of the mounting tube, a telescopic hole being provided at the top end of the detection tube, and a sealing plate being embedded in the bottom end of the detection tube, wherein a first spring abutting against the sealing plate is installed in the detection tube, a telescopic rod is fixed at the top end of the sealing plate, the top end of the telescopic rod is slidably inserted in the telescopic hole, and blocks that are equidistantly elastically inserted with the top end of the detection tube are provided on both sides of the outer wall of the telescopic rod.

[0007] In a specific embodiment, a connection hole is provided at the top end of the installation tube, and a control valve is provided at the bottom end of the installation tube.

[0008] In a specific embodiment, a connecting portion is fixed to the bottom end of the detection tube, and a sealing gasket is embedded in the connecting hole.

[0009] In a specific embodiment, the connecting portion is threadedly inserted into the connecting hole, and the bottom end of the connecting portion abuts against the sealing gasket.

[0010] In a specific implementation manner, a non-slip sleeve is fixedly sleeved on the detection tube, and the bottom end of the sealing plate abuts against the connecting portion.

[0011] In a specific implementation manner, an electromagnetic rod is embedded in the telescopic rod, and telescopic grooves are equidistantly provided on both sides of the outer wall of the telescopic rod.

[0012] In a specific implementation, a second spring is embedded in the telescopic slot, and the clamping block is slidably inserted in the telescopic slot and abuts against a side wall of the second spring.

[0013] In a specific implementation manner, a magnetic attraction rod is fixedly connected to the inner wall of the clamping block, and the magnetic attraction rod passes through the second spring and is fixedly engaged with the electromagnetic rod.

[0016] The utility model provides a portable leakage detection device, in which a mounting tube is fixed equidistantly at the top end of a conveying pipeline, and an inspection tube is fixed through the mounting tube. When performing detection, a connecting portion at the bottom end of the detection tube is threadedly inserted into a connecting hole at the top end of the mounting tube, and a control valve on the mounting tube is opened. After detection, the control valve is closed and the detection tube is unscrewed, so that the detection tube can be installed and disassembled easily, thereby improving the convenience of the detection device. A sealing plate and a first spring are embedded in the detection tube, and the pressure in the conveying pipeline squeezes the sealing plate and the first spring to move upward, so that the telescopic rod at the top end of the sealing plate moves synchronously. During the movement of the telescopic rod, the inner wall of the telescopic hole squeezes the card block to shrink into the telescopic groove. When the card block passes through the telescopic hole, the second spring pushes the card block to be clamped with the top of the detection tube. After detection, the telescopic rod cannot be retracted into the detection tube due to the influence of the card block, so that the position of the telescopic rod used for detecting pressure is maintained easily, and the situation that the telescopic rod is reset after disassembly is avoided, thereby improving the practicality of the detection device.

DETAILED DESCRIPTION

[0023] In the prior art, since the two pressure detection structures are at a certain distance, the scales of the two pressure detection structures cannot be observed in real time. However, after the pressure detection structure is disassembled, the elastic force of the spring will cause the scale to reset, which leads to poor practicality of the pressure detection device. Therefore, the inventor provides a portable leakage detection device to solve the above defects.

[0024] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please refer to Figures 1 to 4 The embodiment of the utility model provides a portable leakage detection device, including a conveying pipeline 1 and a mounting tube 2 equidistantly fixed on the outer wall of the conveying pipeline 1, and also including a detection tube 3 detachably fixed on the top of the mounting tube 2, a telescopic hole 19 is opened at the top of the detection tube 3, and a sealing plate 7 is embedded in the bottom end of the detection tube 3, wherein a first spring 11 abutting against the sealing plate 7 is installed in the detection tube 3, a telescopic rod 9 is fixed at the top of the sealing plate 7, the top of the telescopic rod 9 is slidably inserted in the telescopic hole 19, and blocks 8 equidistantly elastically inserted on both sides of the outer wall of the telescopic rod 9 are inserted with the top of the detection tube 3. When performing detection, the connecting portion 6 at the bottom end of the detection tube 3 is threadedly inserted into the connecting hole 12 at the top of the mounting tube 2, and the control valve 4 on the mounting tube 2 is opened, and the control valve 4 is closed after the detection to unscrew the detection tube 3, so as to facilitate the installation and disassembly of the detection tube 3.

[0026] A connecting hole 12 is provided at the top end of the mounting tube 2, and a control valve 4 is installed at the bottom end of the mounting tube 2. A connecting part 6 is fixed to the bottom end of the detection tube 3, and a sealing gasket 13 is embedded in the connecting hole 12. The connecting part 6 is threadedly inserted into the connecting hole 12, and the bottom end of the connecting part 6 abuts against the sealing gasket 13. After the connecting part 6 is tightened, the sealing gasket 13 maintains a seal between the connecting part 6 and the mounting tube 2. An anti-slip sleeve 5 is fixedly sleeved on the detection tube 3, and the bottom end of the sealing plate 7 abuts against the connecting part 6.

[0027] An electromagnetic rod 10 is embedded in the telescopic rod 9, and telescopic grooves 14 are equidistantly provided on both sides of the outer wall of the telescopic rod 9, a second spring 18 is embedded in the telescopic groove 14, the card block 8 is slidably inserted in the telescopic groove 14, and abuts against the side wall of the second spring 18, and a magnetic suction rod 15 is fixedly connected to the inner wall of the card block 8, and the magnetic suction rod 15 passes through the second spring 18 and is fixedly engaged with the electromagnetic rod 10. After detection, the electromagnetic rod 10 is opened to be attracted to multiple magnetic suction rods 15, so that multiple card blocks 8 are simultaneously retracted into the telescopic groove 14, and the elastic force of the first spring 11 pushes the sealing plate 7 to move the telescopic rod 9 downward to reset, thereby improving the convenience of resetting the detection device. An anti-slip portion 17 is fixedly connected to the clamping block 8, and the anti-slip portion 17 is clamped with the inner wall of the telescopic groove 14. An inclined groove 16 is provided on the top of one end of the clamping block 8 extending out of the telescopic groove 14, and the inclined groove 16 abuts against the inner wall of the telescopic hole 19. The pressure in the conveying pipeline 1 squeezes the sealing plate 7 and the first spring 11 to move upward, so that the telescopic rod 9 at the top of the sealing plate 7 moves synchronously. During the movement of the telescopic rod 9, the inner wall of the telescopic hole 19 squeezes the clamping block 8 to shrink into the telescopic groove 14. When the clamping block 8 passes through the telescopic hole 19, the second spring 18 pushes the clamping block 8 to clamp with the top of the detection tube 3. After the detection, the telescopic rod 9 is affected by the clamping block 8 and cannot be retracted into the detection tube 3.

[0028] In summary, when in use, the connecting part 6 at the bottom end of the detection tube 3 is threadedly inserted into the connecting hole 12 at the top of the mounting tube 2, and the control valve 4 on the mounting tube 2 is opened. The pressure in the conveying pipeline 1 squeezes the sealing plate 7 and the first spring 11 to move upward, so that the telescopic rod 9 at the top of the sealing plate 7 moves synchronously. During the movement of the telescopic rod 9, the inner wall of the telescopic hole 19 squeezes the block 8 to shrink into the telescopic groove 14. When the block 8 passes through the telescopic hole 19, the second spring 18 pushes the block 8 to engage with the top of the detection tube 3. After the detection, the control valve 4 is closed and the detection tube 3 is unscrewed. The telescopic rod 9 is affected by the block 8 and cannot be retracted into the detection tube 3, which is convenient for maintaining the position of the telescopic rod 9 used to detect pressure.
