Abstract
Description
Technical Field
[0001] This invention relates to the field of pipeline measurement, and more specifically to a pipeline measurement device. Background Technology
[0002] PE pipes are widely used in various fields such as water supply, gas supply, underfloor heating, electrical cable wiring, agricultural irrigation, and industrial sewage discharge. They retain the rigidity and strength of high-density polyethylene while possessing good flexibility and creep resistance. Their excellent heat-fusion connection performance facilitates pipe installation. PE pipes are resistant to acid and alkali corrosion, do not rust, do not scale, are resistant to aging, and do not breed microorganisms, making them ideal for drinking water transportation. PE pipes exhibit strong adaptability to uneven foundation settlement and misalignment, good seismic resistance, and strong low-temperature impact resistance.
[0003] When determining the location of PE pipes in a concrete layer, a detection operation is required. However, when existing pipe measuring equipment detects and measures PE pipes in a concrete layer, the surface at the detection location is often tilted, making it difficult to determine the detection location. This leads to deviations in detection and measurement, and ultrasonic and other signal measurements are easily affected by external interference. Summary of the Invention
[0004] In view of this, the present invention provides a pipeline measuring device to solve the problems mentioned in the background art.

[0007] The counterweight leveling mechanism includes a counterweight base and a counterweight assembly that can be adjusted horizontally. The counterweight base is fixedly installed on the upper end of the connecting ball, and the counterweight assembly is used to drive the connecting ball to keep the elastic telescopic assembly in a vertical state.
[0008] An acoustic wave detection mechanism is connected to the bottom end of the elastic telescopic component. The acoustic wave detection mechanism includes a mounting shell and an ultrasonic transmitter located at the bottom of the mounting shell, and a plurality of ultrasonic receivers arranged around the ultrasonic transmitter.
[0009] A synchronous support mechanism is arranged around the outside of the installation mechanism, including a conical protective cover and multiple elastic support units arranged in a circle; each elastic support unit includes a support rod hinged to the conical protective cover, a guide sleeve slidably sleeved at the bottom of the support rod, a support pulley at the end of the guide sleeve, and a support spring connecting the support rod and the guide sleeve.
[0010] The drive module includes a drive motor installed in the elastic telescopic component and a drive screw connected to the output end of the drive motor; the drive screw is threadedly connected to the elastic telescopic component to drive the elastic telescopic component to move the acoustic wave detection mechanism downward to press against the surface to be tested.
[0011] Beneficial effects: The counterweight leveling mechanism adjusts the horizontal position through the counterweight component, driving the connecting ball and two arc-shaped mounting covers to rotate and adjust, while keeping the elastic telescopic component vertical. This ensures that the acoustic wave detection mechanism below the elastic telescopic component is always perpendicular to the surface to be measured, thus adapting to the inclined surface and eliminating the detection angle deviation caused by the inclination of the concrete surface. The drive module drives the acoustic wave detection mechanism to press against the surface to be measured, specifically driven by the transmission motor and transmission screw. Combined with the elastic telescopic component to buffer pressure fluctuations, this ensures close contact between the ultrasonic wave transmitter, ultrasonic wave receiver, and the surface to be measured, effectively reducing signal attenuation and external interference. The elastic support unit of the synchronous support mechanism automatically adapts to the unevenness of the ground. Specifically, the support rod and guide sleeve slide together, the support pulley contacts the ground side, and the support spring adapts to the sliding pressure between the support rod and the guide sleeve, ensuring stable contact and anti-interference.

[0014] Beneficial effects: By setting a radial waist-shaped hole in the counterweight base for the level, the center of gravity position can be quickly adjusted by radially sliding the counterweight block and locking it. Combined with the real-time feedback of the level, it ensures that the counterweight base remains horizontal, that is, the entire equipment remains horizontal. The dynamic leveling method eliminates the measurement error caused by the tilt of the equipment. The locking knob and connecting sleeve design simplifies the counterweight adjustment method and is suitable for quick on-site operation. Its operation is convenient.

[0020] Beneficial effects: The elastic layer inside the second connecting rod absorbs the impact force during the pressing process, reducing the rigidity of the contact between the acoustic wave detection mechanism and the concrete surface, which can prevent damage to the acoustic wave detection mechanism from rigid contact; the elastic isolation cover plays the role of vibration isolation and noise reduction, which helps to reduce the transmission of external vibration to the ultrasonic receiver, reduce signal noise, and improve the detection signal-to-noise ratio.
[0021] In some embodiments, the transmission screw passes through the first connecting rod and is threadedly connected to the second connecting rod to drive the acoustic wave detection mechanism to move downward and press against the surface to be tested.
[0022] Beneficial effects: The motor torque is converted into linear downward pressure by the transmission screw. The downward distance and clamping force of the acoustic wave detection mechanism are precisely controlled by the threaded connection, so as to achieve precise pressure control and ensure constant contact force between the acoustic wave detection mechanism and the surface to be tested, avoiding weak signal due to insufficient pressure or damage to the equipment due to excessive pressure.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0052] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.
[0053] An embodiment of the present invention provides a pipeline measuring device, which includes: an installation mechanism 1, a counterweight leveling mechanism 3, an acoustic wave detection mechanism 4, a synchronous support mechanism 2, and a drive module, wherein the synchronous support mechanism 2 is arranged around the outside of the installation mechanism 1.
[0054] like Figure 2 As shown, the mounting mechanism 1 includes a mounting box 101, two arc-shaped mounting covers 107 fixed to the bottom of the mounting box 101, and a connecting ball 108 rotatably connected between the two arc-shaped mounting covers 107; a rotating connecting cavity is formed between the interiors of the two arc-shaped mounting covers 107, and the inner wall of the rotating connecting cavity is in contact with the outer wall of the connecting ball 108 to form a ball-joint connection.
[0055] The installation mechanism 1 also includes an elastic telescopic component, the upper end of which is fixedly set with the connecting ball 108, and the acoustic wave detection mechanism 4 is connected to the bottom end of the elastic telescopic component.
[0056] In specific structural embodiments, such as Figure 3 and Figure 7 As shown, the elastic telescopic assembly includes a first connecting rod 109 and a second connecting rod 110. The top end of the first connecting rod 109 is fixedly connected to the connecting ball 108, and the second connecting rod 110 is slidably sleeved inside the first connecting rod 109.
[0057] In a further embodiment, such as Figure 7 As shown, an elastic layer is filled in the elastic cavity 114 in the middle of the second connecting rod 110. The elastic layer in the second connecting rod 110 absorbs the impact force during the downward pressing process, reducing the rigidity of the contact between the acoustic wave detection mechanism 4 and the concrete surface, thus preventing damage to the acoustic wave detection mechanism 4 from rigid contact. The elastic layer is specifically made of an elastic material, such as a rubber elastic buffer pad.
[0058] According to embodiments of the present invention, such as Figure 7 As shown, the drive module includes a drive motor 112 installed in the elastic telescopic component and a drive screw 113 connected to the output end of the drive motor 112; the drive screw 113 is threadedly connected to the elastic telescopic component to drive the elastic telescopic component to move the acoustic wave detection mechanism 4 downward to press the surface to be tested.
[0059] In some embodiments, the transmission screw 113 passes through the first connecting rod 109 and is threadedly connected to the second connecting rod 110 to drive the acoustic wave detection mechanism 4 to move downward and press against the surface to be tested.
[0060] The motor torque is converted into linear downward pressure by the transmission screw 113. The downward distance and clamping force of the acoustic wave detection mechanism 4 are precisely controlled by the threaded connection to achieve precise pressure control. This ensures that the acoustic wave detection mechanism 4 has a constant contact force with the surface to be tested, and avoids weak signal due to insufficient pressure or damage to the equipment due to excessive pressure.
[0061] In terms of selection, the drive motor 112 can be a high-speed motor of model KOM7080, which has good drive response capability and precision.
[0062] According to embodiments of the present invention, such as Figure 6 and Figure 8 As shown, the counterweight leveling mechanism 3 includes a counterweight base 301 and a counterweight assembly that can be adjusted horizontally. The counterweight base 301 is fixedly installed on the upper end of the connecting ball 108, and the counterweight assembly is used to drive the connecting ball 108 to drive the elastic telescopic assembly to maintain a vertical state.
[0063] In some embodiments, such as Figure 6 and Figure 8As shown, the counterweight base 301 is configured as a disc structure, and the upper end face of the counterweight base 301 is provided with a radial waist-shaped hole and a level. The counterweight assembly includes a locking knob 304 passing through the radial waist-shaped hole, a counterweight block 303 sleeved on the outside of the locking knob 304, and a connecting sleeve 305 threaded to the bottom end of the locking knob 304. The position of the counterweight block 303 on the radial waist-shaped hole is adjusted and locked by radial sliding, so that the upper end face of the counterweight base 301 remains horizontal.
[0064] A radial waist-shaped hole is set on the counterweight seat 301 for the level. By radially sliding the counterweight block 303 and locking it, the center of gravity position can be quickly adjusted. Combined with the real-time feedback of the level, it is ensured that the counterweight seat 301 remains horizontal, that is, the entire equipment remains horizontal. The dynamic leveling method eliminates the measurement error caused by the tilt of the equipment. The design of the locking knob 304 and the connecting sleeve 305 simplifies the counterweight adjustment method and is suitable for quick on-site operation. Its operation is convenient.
[0065] In some embodiments, such as Figure 6 and Figure 8 As shown, multiple radial oblong holes are provided, with the extension direction of any one of them intersecting the central axis of the counterweight base 301. Multiple levels are also provided, arranged in a circular pattern on the outer edge of the upper surface of the counterweight base 301. The levels and counterweight blocks 303 are positioned to avoid obstruction in their sliding positions on the radial oblong holes. The multiple radial oblong holes in different radial directions support multi-angle counterweight adjustment, forming a multi-dimensional balance adjustment capable of handling complex inclined surfaces. The circularly arranged levels comprehensively monitor the levelness of the counterweight base 301 in all directions, avoiding detection deviations caused by local unevenness and achieving full-coverage level monitoring. Furthermore, the design that avoids obstruction by placing the levels on the outer edge of the upper surface of the counterweight base 301 ensures unobstructed observation and facilitates user observation.
[0066] The pipeline measuring equipment provided in this embodiment uses a counterweight leveling mechanism 3 for horizontal adjustment via a counterweight assembly. This drives the connecting ball 108 and the two arc-shaped mounting covers 107 to rotate and adjust, while keeping the elastic telescopic assembly vertical. This ensures that the acoustic wave detection mechanism 4 below the elastic telescopic assembly is always perpendicular to the surface to be measured, thus adapting to the tilted surface and eliminating the detection angle deviation caused by the tilt of the concrete surface. The acoustic wave detection mechanism 4 is driven by a drive module to press against the surface to be measured, specifically by a drive motor 112 and a drive screw 113. Combined with the elastic telescopic assembly to buffer pressure fluctuations, this ensures that the ultrasonic wave transmitter and receiver 405 are in close contact with the surface to be measured, effectively reducing signal attenuation and external interference.
[0067] According to embodiments of the present invention, such as Figure 7 and Figure 9As shown, the acoustic wave detection mechanism 4 includes a mounting housing 401 and an ultrasonic transmitter 404 located at the bottom of the mounting housing 401, and a plurality of ultrasonic receivers 405 arranged around the ultrasonic transmitter 404.
[0068] According to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the synchronous support mechanism 2 includes a conical protective cover 201 and multiple elastic support units arranged in a circular pattern; as Figures 3 to 5 As shown, each elastic support unit includes a support rod 203 hinged to the conical protective cover 201, a guide sleeve 204 slidably sleeved at the bottom of the support rod 203, a support pulley 202 located at the end of the guide sleeve 204, and a support spring 208 connecting the support rod 203 and the guide sleeve 204.
[0069] In some embodiments, such as Figure 4 As shown, the elastic support unit also includes a limiting link 206. The top end of the limiting link 206 is hinged to the conical protective cover 201, and the bottom end is inserted into the waist-shaped groove on the side wall of the support rod 203 to limit the unfolding angle of the support rod 203. The support rod 203 and the guide sleeve rod 204 are fixed together by a connecting insert 207.
[0070] The limiting link 206 and the waist-shaped groove are used to limit the unfolding angle of the support rod 203, prevent over-expansion, and avoid the elastic support unit from becoming unstable due to over-expansion; the guide sleeve 204 and the support rod 203 are slidably connected and fixed by the connecting plug 207, which can adjust the support length for different ground heights to ensure that the conical protective cover 201 is stably supported on various uneven concrete surfaces.
[0071] The pipeline measuring device provided in this embodiment automatically adapts to the unevenness of the ground through the elastic support unit of the synchronous support mechanism 2. Specifically, the support rod 203 and the guide sleeve rod 204 slide together, the support pulley 202 contacts the ground side, and the support spring 208 adapts to the sliding pressure between the support rod 203 and the guide sleeve rod 204 to ensure stable contact and anti-interference. The pipeline measuring device provided by this invention can achieve self-balancing, self-adaptive support and precise pressure, which significantly improves the positioning accuracy and anti-environmental interference ability of PE pipelines in concrete layers.
[0072] In the specific implementation of the structure, such as Figure 4As shown, limiting rods 206 can be installed on both sides of the upper end of the support rod 203. Both sides of the support rod 203 are provided with waist-shaped grooves. The bottom end of the limiting rod 206 is inserted into the inner side of the waist-shaped groove. The elastic support unit also includes mounting limiting seats 205. Multiple mounting limiting seats 205 are provided, arranged around the conical protective cover 201. The upper end of the limiting rod 206 is rotatably connected to the mounting limiting seat 205 via a pin. The limiting rods 206 and waist-shaped grooves on both sides of the upper end of the support rod 203 respectively help to strengthen structural limiting and improve the deployment accuracy of the elastic support unit.
[0073] In the specific implementation of the structure, such as Figure 5 As shown, two support springs 208 are provided at the bottom end of the support rod 203. The bottom end of the support rod 203 is connected to the guide sleeve rod 204 through the two support springs 208. A connecting rod 207 is installed between two adjacent support springs 208. The upper end of the connecting rod 207 passes through the guide sleeve rod 204 and is inserted into the inner side of the bottom end of the support rod 203. The upper end of the connecting rod 207 is connected to the support rod 203 by a thread. The support springs 208 can meet the elastic support of multiple elastic support units for the whole.
[0074] In some embodiments, such as Figure 7 As shown, the acoustic wave detection mechanism 4 is connected to the bottom end of the second connecting rod 110 via an elastic isolation cover 111. When the drive module drives the acoustic wave detection mechanism 4 to move downward, the second connecting rod 110, through the elastic isolation cover 111, moves the acoustic wave detection mechanism 4 downward between multiple elastic support units and into close contact with the surface of the position to be measured, effectively improving the transmission of ultrasonic waves. Furthermore, the elastic isolation cover 111 functions as vibration isolation and noise reduction, which helps reduce the transmission of external vibrations to the ultrasonic receiver 405, lowers signal noise, and improves the detection signal-to-noise ratio. Specifically, the elastic isolation cover 111 can be configured as an elastic rubber isolation cover.
[0075] In some embodiments, such as Figure 9 As shown, the bottom of the mounting housing 401 is fixed with an ultrasonic transmitter 404 and multiple ultrasonic receivers 405 by a sealing plate 402. The outer side of the mounting housing 401 is covered with a protective sleeve 403. The upper part of the mounting box 101 is provided with a control panel 103. A pressure sensor is provided at the connection between the elastic isolation cover 111 and the second connecting rod 110. The pressure sensor is electrically connected to the control panel 103, and the drive motor 112 is electrically connected to the control panel 103.
[0076] The sealing disc 402 prevents moisture, dust and other impurities from entering the ultrasonic device, and the protective sleeve 403 resists mechanical scratches, improving reliability and extending equipment life; the pressure sensor provides real-time feedback of contact pressure to the control panel 103, which controls the start and stop of the drive motor 112 to achieve constant pressure detection and adjustment, avoiding the impact of uneven pressure caused by human operation on measurement accuracy.
[0077] In some embodiments, such as Figure 2 As shown, the installation mechanism 1 also includes a sealing cover 102 on the installation box 101 and an installation box 106 below the sealing cover 102. The installation box 106 has a built-in wireless transmission module and a processor. The wireless transmission module is wirelessly connected to the pressure sensor and electrically connected to the processor. The processor is electrically connected to the drive motor 112. The processor is configured to control the start and stop of the drive motor 112 according to the feedback signal of the pressure sensor to maintain a constant contact pressure between the acoustic wave detection mechanism 4 and the surface to be measured.
[0078] The pipeline measurement equipment provided in this embodiment uses a processor to dynamically adjust the drive motor 112 based on the pressure signal, maintaining a constant pressure between the acoustic detection mechanism 4 and the surface to be measured, thus eliminating interference from human factors. The wireless transmission module supports remote data monitoring and command issuance, improving operational safety in complex environments (such as deeply buried pipelines).
[0079] During operation, the pressure sensor can monitor the degree of contact between the elastic isolation cover 111 and the concrete surface, which allows the user to control the descent height of the acoustic detection mechanism 4 through the control panel 103 and peripheral commands.
[0080] In some embodiments, such as Figure 1 and Figure 2 As shown, the mounting mechanism 1 also includes a handle 104 fixed to the upper end of the mounting box 101 and a battery pack 105 installed inside the mounting box 101. The battery pack 105 is used for power supply. The design of the battery pack 105 and the handle 104 enhances the portability of the device and is suitable for outdoor or power-free scenarios.
[0081] In a preferred embodiment, the connecting ball 108 is configured as a hollow structure to reduce the weight at the top, lower the center of gravity, improve stability, and provide space to facilitate the wiring and layout of devices and other facilities.
[0082] In some embodiments, the inner wall of the elastic shield 111 is provided with an electromagnetic shielding layer (not shown in the figure). The electromagnetic shielding layer can block external electromagnetic signals from interfering with the ultrasonic receiver 405, ensuring accurate detection data in a strong electromagnetic environment.
[0083] In a preferred embodiment, the number of ultrasonic receivers 405 is 4-8, and they are arranged in an equidistant circle with the ultrasonic transmitter 404 as the center; the mounting box 101 is configured as a regular polygonal structure, and the center of the mounting box 101 is collinear with the central axis of the circular arrangement of the multiple ultrasonic receivers 405.
[0084] With this design, the receivers, arranged in an equidistant circle, capture sound wave reflection signals from multiple directions to obtain more accurate information on the location and depth of the pipe. The regular polygonal design of the mounting box 101 is collinear with the center of the receiver, optimizing the structure, reducing the risk of equipment center of gravity shift, ensuring structural stability during detection, and improving data reliability.
[0085] The pipeline measuring device provided in this embodiment is used as follows:
[0086] When detecting PE pipes in concrete, the acoustic detection mechanism 4 is vertically zeroed. Specifically, the upper end of the connecting ball 108 is fitted between the two arc-shaped mounting covers 107, so that the connecting ball 108 remains vertically stable under the gravity of the first connecting rod 109, the second connecting rod 110, the elastic isolation cover 111, and the acoustic detection mechanism 4. The upper end face of the counterweight 301 is provided with multiple radial oblong holes, and the bottom end of the locking knob 304 passes through the counterweight 303 and the radial oblong holes. It is connected to the connecting sleeve 305 by threads. The counterweight 303 is horizontally adjusted along the radial waist-shaped hole and locked to the counterweight seat 301 by the locking knob 304 and the connecting sleeve 305. The level of the counterweight seat 301 can be displayed by the level instrument. The counterweight 303 is adjusted radially along the counterweight seat 301 by multiple locking knobs 304, so that the upper end face of the counterweight seat 301 can be adjusted to a horizontal state, keeping the sound wave detection mechanism 4 in a vertical state.
[0087] The entire unit is lifted and placed at the detection position by the handle 104. At this time, the support pulleys 202 at the bottom of the multiple elastic support units can contact the ground and roll. Then, the multiple guide sleeves 204 rotate synchronously relative to the mounting limit seat 205 through the support rod 203, thereby realizing the unfolding operation of multiple elastic support units relative to the polygonal mounting box 101. The unfolding angle of the multiple elastic support units can be limited by the limit link 206 and elastic protection is provided by the conical protective cover 201. The support rod 203 and the guide sleeve 204 are connected by two support springs 208. The support springs 208 can satisfy the elastic support of multiple elastic support units for the whole. Then, the hollow connecting ball 108 swings inside the two arc-shaped mounting covers 107 and drives the acoustic wave detection mechanism 4 to remain vertical through the first connecting rod 109, the second connecting rod 110 and the elastic isolation cover 111, so as to avoid the surface of the test position being tilted and causing the detection position deviation.
[0088] When the power is turned on, the drive motor 112 is started, causing the drive motor 112, supported by the first connecting rod 109, to drive the second connecting rod 110 downward through the drive screw 113. The second connecting rod 110 then drives the acoustic wave detection mechanism 4 downward between multiple elastic support units via the elastic isolation cover 111, making it in close contact with the surface to be tested, effectively improving the transmission of ultrasonic waves. An ultrasonic transmitter 404 and multiple ultrasonic receivers 405 are installed inside the mounting shell 401, with the multiple ultrasonic receivers 405 arranged circumferentially relative to the ultrasonic transmitter 404. Ultrasonic waves are emitted by the ultrasonic transmitter 404 and synchronously received by the multiple ultrasonic receivers 405, enabling accurate detection of PE pipes in concrete. A protective sleeve 403 covers the outside of the mounting shell 401, and a shielding layer is provided on the inner wall of the elastic isolation cover 111. The protective sleeve 403 and the shielding layer seal and shield the ultrasonic transmitter 404 and ultrasonic receivers 405, preventing external interference from affecting the ultrasonic wave reception.
[0089] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
