Abstract
Description
Technical Field
[0001] This utility model relates to the field of air resistance detection technology, and in particular to an air resistance detector for primary network pipelines. Background Technology
[0002] The primary pipeline network refers to the network from the main heat source of the centralized heating system to the heat exchange stations of each heating community. Air resistance can sometimes occur in the pipelines of the primary network. Air resistance can lead to increased liquid flow resistance and reduced flow velocity in the pipeline, as well as insufficient water pressure and accelerated pipeline corrosion. Therefore, it is necessary to regularly check the air resistance of the primary network pipelines.
[0003] In existing technologies, air resistance is mainly detected by pressure sensors, flow meters, or manual inspection. When detecting air resistance, pressure sensors and flow meters require manual judgment based on water pressure and flow rate, which can lead to inaccurate results. Furthermore, the disassembly and assembly of pressure sensors and flow meters are cumbersome, resulting in low detection efficiency. Manual inspection mainly involves tapping the pipe and listening to the sound, which not only requires a high level of experience from the inspector but also yields inaccurate results, making it prone to mishearing or oversight.
[0004] Therefore, there is an urgent need to provide a primary network pipeline air resistance detector to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a primary network pipeline gas resistance detector.
[0006] To solve the above technical problems, the present invention adopts a technical solution as follows: a primary network pipeline air resistance detector is provided, including a detector body and a gripping part. The bottom end of the detector body is provided with a connecting line mechanism for transmitting electrical signals, the other end of the connecting line mechanism is connected to the gripping part, and a pressing mechanism is provided on one side of the gripping part.
[0007] The gripping part is provided with a fixing mechanism for clamping the pipeline;
[0008] The gripping part is also provided with a connecting mechanism, and a fixing mechanism two for clamping the pipeline is fixed at the top of the connecting mechanism.
[0009] The present invention is further configured such that: the connecting wire mechanism includes a protective sleeve, and a first wire is disposed inside the protective sleeve, and a second wire is also disposed inside the protective sleeve.
[0010] The above technical solution provides a display screen and operation buttons on the detector body. The detector body contains an electronic board, a comparator, an analog-to-digital converter, and a rechargeable battery. The detector body is electrically connected to the detection part through wire one and wire two, enabling the detector body to receive electrical signals transmitted from the detection part and process the electrical signals to determine whether there is air resistance in the pipeline.
[0011] The present invention is further configured such that: the pressing mechanism includes a pressing member rotatably disposed on the inner wall of one side of the gripping part, and a transmission groove plate is fixed on the pressing member.
[0012] Through the above technical solution, the pressing part has a hollow structure and several grooves on its outside that match the shape of the fingers, which improves the comfort of gripping and pressing. The transmission groove plate has a hollow arc-shaped plate structure. When the pressing part is pressed, the transmission groove plate will rotate accordingly.
[0013] The present invention is further configured such that: the fixing mechanism includes a lower clamp fixed to the top of the gripping part, and at least two ultrasonic transducers are provided on the inner side of the lower clamp.
[0014] Through the above technical solution, the lower clamp has an arc-shaped structure, and the ultrasonic transducer has the function of emitting ultrasonic waves and receiving ultrasonic waves and converting them into electrical signals. The ultrasonic transducer is electrically connected to the detector body through the wire, so that the electrical signal can be transmitted to the detector body.
[0015] The present invention is further configured such that: the connecting mechanism includes a sliding rod slidably disposed on the top wall of the gripping part, a connecting plate is fixed at the bottom end of the sliding rod, and a compression spring is disposed on the connecting plate.
[0016] With the above technical solution, the sliding rod can slide up and down along the gripping part, while the compression spring and connecting plate can push the sliding rod downward to provide clamping force.
[0017] The present invention is further configured such that: a connecting rod is fixed at the bottom end of the connecting plate, and a slider is provided at the bottom end of the connecting rod.
[0018] With the above technical solution, the slider is set in the arc-shaped groove inside the transmission slot. When the user presses down the pressing piece, the transmission slot rotates, forcing the slider to move upward along the arc-shaped groove. At this time, the connecting rod and connecting plate rise, causing the sliding rod and the upper clamp to rise. The upper clamp moves in the opposite direction to the lower clamp, increasing the distance between the two clamps. The user can place the pipe between the lower clamp and the upper clamp and release the pressing piece. Under the elastic force of the compression spring, the upper clamp and the lower clamp will clamp the pipe.
[0019] The present invention is further configured such that: the fixing mechanism II includes an upper clamp fixed to the top of the sliding rod, and at least two ultrasonic transducers II are fixed on the inner side of the upper clamp.
[0020] Through the above technical solution, the upper clamp has an arc-shaped structure, and the second ultrasonic transducer also has the function of generating ultrasonic waves and receiving ultrasonic waves and converting them into electrical signals. The upper clamp is electrically connected to the detector body through the second wire. After the upper clamp and the lower clamp clamp the pipe, at least two sets of ultrasonic transducers can emit ultrasonic waves to detect the pipe. Since the propagation speed and attenuation of ultrasonic waves are different in liquid and gaseous media, and the acoustic impedance of bubbles and liquids are different, when there are bubbles in the pipe, ultrasonic waves will produce reflection, refraction and scattering phenomena on the surface of the bubbles. By analyzing the changes in these signals, the detector body can determine whether there are bubbles or air resistance in the pipe.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. With the arrangement of the pressing part, transmission groove plate, fixing mechanism one, connecting mechanism and fixing mechanism two, the user only needs to press and release the pressing part to open and close the clamping structure, thereby effectively improving the installation and testing efficiency of the device;
[0023] 2. This utility model achieves ultrasonic detection of gas resistance in pipelines by setting up a detector body, ultrasonic transducer one, and ultrasonic transducer two, resulting in more accurate detection results and higher detection efficiency. Attached Figure Description

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0030] Please see Figures 1-4 A primary pipeline air resistance detector includes a detector body 1 and a gripping part 3. The bottom of the detector body 1 is provided with a connecting wire mechanism 2 for transmitting electrical signals. The connecting wire mechanism 2 includes a protective sleeve 201. The protective sleeve 201 contains a first wire 202 and a second wire 203. The detector body 1 is provided with a display screen and operation buttons. The detector body 1 contains an electronic board, a comparator, an analog-to-digital converter module, and a rechargeable battery. The detector body 1 is electrically connected to the detection part through the first wire 202 and the second wire 203, so that the detector body 1 can receive the electrical signals transmitted from the detection part and determine whether there is air resistance in the pipeline after processing the electrical signals.
[0031] like Figure 1 and Figure 3 As shown, the other end of the connecting line mechanism 2 is connected to the gripping part 3. A pressing mechanism 4 is provided on one side of the gripping part 3. The pressing mechanism 4 includes a pressing member 401 rotatably disposed on the inner wall of one side of the gripping part 3. A transmission groove plate 402 is fixed on the pressing member 401. The pressing member 401 has a hollow structure and several grooves matching the shape of the fingers are provided on its outside, which improves the comfort of gripping and pressing. The transmission groove plate 402 has a hollow arc-shaped plate structure. When the pressing member 401 is pressed, the transmission groove plate 402 will rotate accordingly.
[0032] like Figure 3As shown, the gripping part 3 is provided with a fixing mechanism 5 for clamping the pipeline. The fixing mechanism 5 includes a lower clamp 501 fixed to the top of the gripping part 3. At least two ultrasonic transducers 502 are provided on the inner side of the lower clamp 501. The lower clamp 501 has an arc-shaped structure. The ultrasonic transducers 502 have the function of emitting ultrasonic waves and receiving ultrasonic waves and converting them into electrical signals. The ultrasonic transducers 502 are electrically connected to the detector body 1 through the wire 202, so that the electrical signals can be transmitted to the detector body 1.
[0033] like Figure 4 As shown, a connecting mechanism 6 is also provided on the gripping part 3. The connecting mechanism 6 includes a sliding rod 601 slidably disposed on the top wall of the gripping part 3. A connecting plate 602 is fixed to the bottom end of the sliding rod 601. A compression spring 603 is provided on the connecting plate 602. A connecting rod 604 is fixed to the bottom end of the connecting plate 602, and a slider 605 is provided at the bottom end of the connecting rod 604. The sliding rod 601 can slide up and down along the gripping part 3, while the compression spring 603 and the connecting plate 602 can push the sliding rod 601 downward to provide clamping force. The slider 605 is disposed in the transmission groove 402. In the inner arc-shaped groove, when the user presses down the pressing piece 401, the transmission groove piece 402 rotates, forcing the slider 605 to move upward along the arc-shaped groove. At this time, the connecting rod 604 and the connecting plate 602 rise, causing the sliding rod 601 and the upper clamp 701 to rise. At this time, the upper clamp 701 moves in the opposite direction to the lower clamp 501, increasing the distance between the two clamps. The user can place the pipe between the lower clamp 501 and the upper clamp 701 and release the pressing piece 401. Under the elastic force of the compression spring 603, the upper clamp 701 and the lower clamp 501 will clamp the pipe.
[0034] like Figure 1 and Figure 3 As shown, the top of the connecting mechanism 6 is fixed with a fixing mechanism 7 for clamping the pipeline. The fixing mechanism 7 includes an upper clamp 701 fixed to the top of the sliding rod 601. At least two ultrasonic transducers 702 are fixed on the inner side of the upper clamp 701. The upper clamp 701 has an arc-shaped structure. The ultrasonic transducers 702 also have the function of generating ultrasonic waves and receiving ultrasonic waves and converting them into electrical signals. The upper clamp 701 is electrically connected to the detector body 1 through a wire 203. After the upper clamp 701 and the lower clamp 501 clamp the pipeline, at least two sets of ultrasonic transducers can emit ultrasonic waves to detect the pipeline. Since the propagation speed and attenuation of ultrasonic waves are different in liquid and gas media, and the acoustic impedance of bubbles and liquids are different, when there are bubbles in the pipeline, ultrasonic waves will be reflected, refracted and scattered on the surface of the bubbles. By analyzing the changes in these signals, the detector body 1 can determine whether there are bubbles or air resistance in the pipeline.
[0035] When using this invention, the user can hold the detector body 1 with one hand and the gripping part 3 with the other, and press the pressing mechanism 4 to open the upper clamp 701. Then, place the lower clamp 501 and the upper clamp 701 outside the pipe and release the pressing mechanism 4. At this time, the upper clamp 701 and the lower clamp 501 will automatically clamp the pipe under the action of the compression spring 603. The user can use the detector body 1 to detect whether there is air resistance in the pipe. The installation process of this device is convenient and quick, and effectively improves the detection efficiency.
