Description

Technical Field

[0001] The present invention relates to the field of leak detectors, and in particular to a highly sensitive intelligent leak detector. Background Art

[0002] A leak detector is a device used to detect whether there are leaks in pipelines, containers or other closed systems. It determines the location and size of the leak by receiving and analyzing the sound signals generated by gas or liquid leaks.

[0003] The existing leak detector main body generally adopts high-precision sensors such as ultrasonic or piezoelectric sensors, combined with wide-band response, noise suppression technology and high sampling rate, which can accurately capture weak leak sound signals, thus achieving highly sensitive detection. In the traditional leak detector main body, the sensor mainly relies on directly receiving sound signals on the object surface or in the air. When used in a noisy environment, external noise easily interferes with the detection of leak sound signals, reducing the accuracy and precision of leak sound detection. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the traditional leak detector main body, the sensor mainly relies on directly receiving sound signals on the object surface or in the air. When used in a noisy environment, external noise easily interferes with the detection of leak sound signals, reducing the accuracy and precision of leak sound detection.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a highly sensitive intelligent leak detector, including a leak detector main body. On one side of the leak detector main body, knob blocks are symmetrically and rotatably installed. A loudspeaker is arranged on one side of the leak detector main body. A wire is inserted and connected at the interface of the leak detector main body. One end of the wire is fixedly installed with a sensor. A sound insulation device is arranged on the outer surface of the sensor. The sound insulation device can limit and fix a rubber airbag at the outer surface of one end of the sensor through a limiting framework, so as to achieve the effect of blocking external sounds during detection. At the same time, the limiting framework can be adjusted according to the use requirements by means of an adjustment mechanism, thereby changing the blocking range.

[0006] The effects achieved by the above components are as follows: When using the leak detector main body to detect the sound leakage of water pipes inside a building, the wire on one side of the sensor can be inserted into the connection hole of the leak detector main body. Then, by operating the knob block, the leak detector main body and the sensor are started, and the sensor is placed and attached to the position to be detected. After the sensor receives the ultrasonic sound leakage signal, the signal is transmitted to the leak detector main body through the wire, and then a sound prompt is issued by the speaker. When the sensor is placed on the surface of the object to be detected, the sound insulation device is also placed on the surface of the object and covers the outer surface of the sensor to block external sounds. At the same time, according to the usage requirements, the blocking range is adjusted to optimize the aggregation effect and change the sound collection range, improving the accuracy and precision of sound leakage detection.

[0007] Preferably, the sound insulation device includes an arc-shaped frame, a plurality of limiting skeletons and rubber air bags. A detachable device is provided between one side of the arc-shaped frame and the outer surface of the sensor. A plurality of first springs are fixedly installed on one side of the arc-shaped frame. The rubber air bags are arranged inside the inner walls of the plurality of limiting skeletons; a circular ring frame, one ends of the plurality of first springs are fixedly installed on one side of the circular ring frame. One end of the sensor is inserted into the inner walls of the arc-shaped frame and the circular ring frame; an adjusting mechanism is arranged between the plurality of limiting skeletons and the circular ring frame and is used for adjusting the limiting skeletons to change the blocking range; an inflation mechanism is arranged between the rubber air bags and the circular ring frame and is used for inflating the inside of the rubber air bags so that their outer surfaces can closely adhere to the object during use.

[0008] The effects achieved by the above components are as follows: By setting the sound insulation device, when the sensor is placed on the surface of the object to be detected, one side of the plurality of limiting skeletons and the outer surface of the rubber air bag are driven to abut against the surface of the object. Then, according to the size of the detection range required and the actual usage situation, the range surrounded by the plurality of limiting skeletons is adjusted through the adjusting mechanism, which will drive the rubber air bag to be pulled open to optimize the aggregation effect and change the sound collection range. Then, while holding the sensor, the inflation mechanism can be pressed to inflate the inside of the rubber air bag, causing it to expand between the inner wall of the limiting skeleton and the plurality of limiting skeletons, completely covering the outer surface of the detection end of the sensor tightly, thereby isolating external sounds and avoiding interference with the detection of sound leakage signals, improving the accuracy and precision of sound leakage detection.

[0009] Preferably, the adjusting mechanism includes a plurality of abutting plates, one side of the plurality of abutting plates is fixedly installed on one side of the limiting framework; a plurality of telescopic rods, both ends of the plurality of telescopic rods are respectively fixedly installed on one side of the plurality of limiting frameworks and the outer surface of the circular ring frame; a plurality of springs, the inner walls of the plurality of springs are respectively sleeved on the outer surfaces of the plurality of telescopic rods, and both ends are respectively fixedly installed on one side of the plurality of limiting frameworks and the outer surface of the circular ring frame; a threaded rod, one end of the threaded rod is spirally penetrated and installed on one side of the circular ring frame; a conical ring block, the inner wall of the conical ring block is sleeved on the outer surface of the sensor, and one side is rotatably connected to one end of the threaded rod, and one side of the conical ring block abuts against one side of the abutting plate.

[0010] The effects achieved by the above components are as follows: By setting the adjusting mechanism, when it is necessary to adjust the range enclosed by the limiting framework according to the usage requirements, the threaded rod can be manually rotated spirally in the inner wall of the circular ring frame to a certain position, and then it drives the conical ring block sleeved on the sensor to slide towards one end. The outer surface of one end will abut against the abutting plate, pushing it outwards, driving the plurality of limiting frameworks to expand outwards under the limitation of the telescopic rods and the second springs, causing the telescopic rods and the second springs to be stretched, and at the same time stretching the rubber airbag, so as to adjust the sound receiving range, optimize the aggregation effect and change the sound collection range, and improve the accuracy and precision of sound leakage detection.

[0011] Preferably, a plurality of rollers are rotatably connected to one side of the abutting plate, and the rollers are arranged on the side of the abutting plate away from the limiting framework.

[0012] The effects achieved by the above components are as follows: By setting the rollers, the abutting friction between the abutting plate and the conical ring block can be reduced, which is convenient for pushing the abutting plate.

[0013] Preferably, the inflation mechanism includes an air box, the inner wall of the air box is fixedly installed on the outer surface of the circular ring frame, and one side is fixedly connected to one end of the rubber airbag. A plurality of through holes are opened on one side of the inner wall of the air box, and the through holes connect the inner wall of the air box and the inner wall of the rubber airbag to form a sealed space; a push frame, several ends of the push frame penetrate through one side of the air box and extend into the inner wall; a piston plate, the outer surface of the piston plate is slidably connected to the inner wall of the air box, and one side is fixedly connected to one side of the push frame; a plurality of third springs, the plurality of third springs are respectively sleeved on the outer surfaces of several ends of the push frame, and both ends are respectively fixedly installed on one side of the inner wall of the air box and one side of the piston plate.

[0014] The effects achieved by the above components are as follows: By setting up the inflation mechanism, after the limiting skeleton and the rubber airbag are abutted against the surface of the object to be detected, the push frame can be pressed to drive the piston plate to slide towards one end along the inner wall of the air tank, stretching its third spring. The piston plate squeezes the air inside the air tank into the airbag through the through hole, causing it to expand, so that the joint can fit more tightly, improving the sound insulation effect and adapting to different usage scenarios at the same time.

[0015] Preferably, the detachable device includes a U-shaped block, both ends of which are fixedly installed on the outer surface of the sensor. A threaded hole is provided on one side of the inner wall of the U-shaped block; a threaded hole block, one side of which is fixedly installed on one side of the arc-shaped frame and one end of which is inserted into the inner wall of the U-shaped block; a bolt, one end of which is spirally inserted into the inner walls of the threaded hole block and the threaded hole.

[0016] The effects achieved by the above components are as follows: By setting up the detachable device, when the sound insulation device needs to be replaced, the bolt can be manually screwed out from the inner walls of the threaded hole and the threaded hole block, and then the arc-shaped frame is pulled downwards, and the threaded hole block can be pulled out from the inner wall of the U-shaped block and disassembled from the sensor, which is convenient for replacement.

[0017] Preferably, one end of the bolt is fixedly installed with a connecting rope, and one end of the connecting rope is fixedly installed on one side of the arc-shaped frame.

[0018] The effects achieved by the above components are as follows: By setting up the connecting rope, the bolt can be limited on the arc-shaped frame, so that it is not easy to be lost after being pulled out from the inner walls of the threaded hole and the threaded hole block.

[0019] Preferably, a control module is arranged inside the main body of the leak detector. The sensor is electrically connected to the control module by means of a wire, and both the speaker and the knob block are electrically connected to the control module.

[0020] The effects achieved by the above components are as follows: During detection, by operating the knob block, the command can be uploaded to the control module for analysis. After analysis, a command is issued to start the main body of the leak detector and the sensor. When the sensor detects and receives an ultrasonic leak sound signal, the signal will be transmitted to the control module on the main body of the leak detector through the wire for analysis and storage, and then a sound prompt will be issued by the speaker.

[0021] The beneficial effects of the present invention are:

[0022] By setting up a sound insulation device, when the sensor is placed on the surface of the object to be detected, one side of a number of limiting frameworks will be driven to abut against the outer surface of the rubber airbag on the surface of the object. Then, according to the size of the detection range required and the actual usage situation, the range enclosed by the number of limiting frameworks can be adjusted through an adjusting mechanism, which will drive the rubber airbag to be pulled apart to optimize the aggregation effect and change the sound collection range. Then, while holding the sensor, the inflation mechanism can be pressed to inflate the inside of the rubber airbag, causing it to expand between the inner wall of the limiting framework and the number of limiting frameworks, tightly covering the outer surface of the detection end of the sensor completely, so as to isolate the external sound, avoid interference with the detection of leakage signals, and improve the accuracy and precision of leakage sound detection.

[0037] Figure 1-10A high-sensitivity intelligent leak detector shown in the figure includes a leak detector main body 1. On one side of the leak detector main body 1, knob blocks 6 are symmetrically and rotatably installed. A speaker 7 is arranged on one side of the leak detector main body 1. A wire 4 is inserted and connected at the interface of the leak detector main body 1. One end of the wire 4 is fixedly installed with a sensor 5 (model: UT-CS002). A sound insulation device 2 is arranged on the outer surface of the sensor 5. The sound insulation device 2 can limit and fix the rubber airbag 26 at one end outer surface of the sensor 5 through a limit frame 24, so as to achieve the effect of blocking external sounds during detection. At the same time, the limit frame 24 can be adjusted by means of an adjustment mechanism 25 according to the use requirements, so as to change the blocking range. When using the leak detector main body 1 to detect the sound leakage of the water pipes inside the building, the wire 4 on one side of the sensor 5 can be inserted into the connection hole of the leak detector main body 1, and then the leak detector main body 1 and the sensor 5 are started by operating the knob block 6, and the sensor 5 is placed and attached to the position to be detected. After the sensor 5 receives the ultrasonic sound leakage signal, the signal will be transmitted to the leak detector main body 1 through the wire 4, and then a sound prompt will be issued by the speaker 7. When the sensor 5 is placed on the surface of the object to be detected, the sound insulation device 2 will also be placed on the surface of the object and cover the outer surface of the sensor 5 to block external sounds. At the same time, according to the use requirements, the blocking range is adjusted to optimize the aggregation effect and change the sound collection range, so as to improve the accuracy and precision of the sound leakage detection.

[0038] Figure 2-9The sound insulation device 2 shown includes an arc-shaped frame 21, a plurality of limiting skeletons 24, and a rubber airbag 26.

The rubber airbag 26 is arranged in the inner walls of the plurality of limiting skeletons 24; a circular ring frame 23, one ends of the plurality of first springs 22 are fixedly installed on one side of the circular ring frame 23, and one end of the sensor 5 is inserted into the inner walls of the arc-shaped frame 21 and the circular ring frame 23; an adjusting mechanism 25, which is arranged between the plurality of limiting skeletons 24 and the circular ring frame 23 and is used to adjust the limiting skeletons 24 to change the blocking range; an inflation mechanism 27, which is arranged between the rubber airbag 26 and the circular ring frame 23 and is used to inflate the inside of the rubber airbag 26 so that its outer surface can closely adhere to an object during use. When the sensor 5 is placed on the surface of an object to be detected, it will drive one side of the plurality of limiting skeletons 24 and the outer surface of the rubber airbag 26 to abut against the surface of the object. Then, according to the size of the detection range required and the actual usage situation, the adjusting mechanism 25 can be used to adjust the range surrounded by the plurality of limiting skeletons 24, which will drive the rubber airbag 26 to be pulled apart to optimize the aggregation effect and change the sound collection range. Then, while holding the sensor 5, the inflation mechanism 27 can be pressed to inflate the inside of the rubber airbag 26, causing it to expand between the inner walls of the limiting skeletons 24 and the plurality of limiting skeletons 24, completely covering the outer surface of the detection end of the sensor 5 tightly, so as to isolate external sounds, avoid interference and leakage of detection signals, and improve the accuracy and precision of leakage sound detection. When one side of the sensor 5 is closely attached to the surface of the object to be detected, according to the distance between one end of the adjusted limiting skeleton 24 and one end of the sensor 5, after being placed on the object surface, it will push the limiting skeleton 24 and the circular ring frame 23 to move towards one end, driving the first spring 22 to contract. At the same time, the first spring 22 will provide a reverse thrust for resetting the limiting skeleton 24 and the circular ring frame 23, so that it can closely adhere to the surface of the object while not interfering with the detection of the sensor 5, and the outer surfaces of the adjusted limiting skeleton 24 and the rubber airbag 26 at one end can also closely adhere to the surface of the object.

When the sensor 5 detects and receives an ultrasonic leak sound signal, the signal will be transmitted to the control module on the leak detector main body 1 through the wire 4 for analysis and storage, and then a sound prompt will be emitted by the speaker 7.

[0042] Working principle: When using the leak detector main body 1 to detect the sound leakage of water pipes inside a building, the wire 4 on one side of the sensor 5 can be inserted into the connection hole of the leak detector main body 1. Then, by operating the knob block 6, the leak detector main body 1 and the sensor 5 are started, and the sensor 5 is placed and attached to the position to be detected. After the sensor 5 receives the ultrasonic sound leakage signal, the signal will be transmitted to the leak detector main body 1 through the wire 4, and then a sound prompt will be issued by the speaker 7. When the sensor 5 is placed on the surface of the object to be detected, one side of a number of limiting skeletons 24 and the outer surface of the rubber airbag 26 will be abutted against the surface of the object. Then, according to the size of the detection range required and the actual usage situation, the range enclosed by a number of limiting skeletons 24 can be adjusted through the adjusting mechanism 25, which will drive the rubber airbag 26 to be pulled apart to optimize the aggregation effect and change the sound collection range. Then, while holding the sensor 5, the inflation mechanism 27 can be pressed to inflate the inside of the rubber airbag 26, causing it to expand between the inner wall of the limiting skeleton 24 and a number of limiting skeletons 24, completely covering the outer surface of the detection end of the sensor 5 tightly, so as to isolate external sounds and avoid interfering with the detection of sound leakage signals, improving the accuracy and precision of sound leakage detection. When one side of the sensor 5 is closely attached to the surface of the object to be detected, according to the distance between one end of the adjusted limiting skeleton 24 and one end of the sensor 5, after being placed on the object surface, it will push the limiting skeleton 24 and the circular ring frame 23 to move towards one end, driving the first spring 22 to contract. At the same time, the first spring 22 will provide a reverse thrust for the reset of the limiting skeleton 24 and the circular ring frame 23, so that while not interfering with the detection of the sensor 5, the outer surfaces of one end of the adjusted limiting skeleton 24 and the rubber airbag 26 can be closely attached to the surface of the object.

[0043] When it is necessary to replace the sound insulation device 2, the bolt 34 can be manually screwed out from the inner walls of the threaded hole 32 and the screw hole block 33, and then the arc-shaped frame 21 can be pulled downward to pull out the screw hole block 33 from the inner wall of the U-shaped block 31 and disassemble it from the sensor 5 for easy replacement and processing.
