[0001] This application belongs to the field of pipeline monitoring technology, and in particular relates to a pipeline full water monitoring device. Background Technology

[0002] Penetration testing is an important part of nuclear power plant maintenance.

Therefore, how to confirm that the pipe is full of water is the key task of the test. Thus, how to measure whether the pipe is full of water is an important research direction.

[0003] The above statements are for the purpose of providing background information in relation to this application only, and do not necessarily constitute prior art. Utility Model Content

[0032] Penetration testing is an important part of nuclear power plant maintenance. The penetration test uses the water method for measurement, but this method requires ensuring that the downstream pipe is completely filled with water. This requirement is crucial for the accuracy of the work. The accuracy of the measurement results can only be guaranteed when the water flow is continuous and there is no air in the pipe. Therefore, how to confirm that the pipe is full of water is the key task of the test. Thus, how to measure whether the pipe is full of water is an important research direction.

[0033] This application provides a pipe full-water monitoring device. In use, the clamping component of the detection unit is clamped outside the pipe. The acoustic wave sensor emits sound waves into the pipe and receives the sound waves reflected back from the pipe. Since the propagation speed of sound waves in water and air is different, the propagation speed of sound waves in the pipe is different when air is present and when air is not present. By utilizing this speed difference, it can be determined whether the pipe is full. When the acoustic wave sensor detects the presence of air in the pipe, the acoustic wave sensor feeds back a signal to the alarm component, which then sounds an alarm to remind personnel that the pipe is not full. In this way, the full-water monitoring of the pipe is realized.

[0034] The following combination Figures 1-4 This application describes a pipeline full-water monitoring device according to an embodiment of the present application.

[0035] See Figures 1-2 As shown, in some embodiments, the pipe full water monitoring device includes at least one detection unit 1. The detection unit 1 includes a mounting bracket 11, a clamping assembly 12, an acoustic sensor 13, and an alarm component 14. The clamping assembly 12 is connected to the mounting bracket 11 and is used to clamp the pipe 2. The acoustic sensor 13 is connected to the mounting bracket 11 and is used to emit sound waves into the pipe 2 and receive sound waves reflected back from the pipe 2. The alarm component 14 is electrically connected to the acoustic sensor 13.

[0036] The detection unit 1 is used to detect whether the pipe 2 is full of water. The number of detection units 1 can be one or more, and the specific number can be arranged according to the location of the pipe 2 to be detected and the length of the pipe 2.

[0037] In some examples, during the penetration test, there are multiple detection units 1, which are arranged at intervals along the length of the pipe 2. The multiple detection units 1 can be distributed at equal intervals, and the distance between two adjacent detection units 1 can be set to 10m. The multiple detection units 1 can also be distributed at non-equal intervals.

[0038] The detection unit 1 includes a mounting bracket 11, a clamping assembly 12, an acoustic sensor 13, and an alarm component 14.

[0039] Mounting bracket 11 can refer to the mounting base for clamping assembly 12, acoustic sensor 13 and alarm component 14, serving to support clamping assembly 12, acoustic sensor 13 and alarm component 14. The material of mounting bracket 11 can be plastic or metal, etc.

[0040] The clamping assembly 12 is used to clamp the outside of the pipe 2, thereby fixing the detection unit 1 outside the pipe 2.

[0041] The acoustic sensor 13 is capable of emitting sound waves and receiving reflected sound waves. The acoustic sensor 13 can be an ultrasonic sensor 13 or the like. The acoustic sensor 13 has a transmitting end and a receiving end. The transmitting end is used to emit sound waves, and the receiving end is used to receive sound waves.

[0042] After the clamping assembly 12 is clamped onto the pipe 2, the acoustic sensor 13 is located on one side of the pipe 2. The acoustic sensor 13 emits sound waves into the pipe 2. After the sound waves travel through the pipe 2 to the pipe wall on the other side of the pipe 2, they are reflected back and received by the acoustic sensor 13. Since the speed of sound propagation in water and air is different, the speed of sound propagation in the pipe 2 is different when there is air and when there is no air. Therefore, the time from emitting the sound wave to receiving the reflected sound wave by the acoustic sensor 13 is different. Based on the time, it can be determined whether the pipe 2 has reached the full water state.

[0043] Alarm component 14 can refer to a component that can issue an alarm prompt, such as a buzzer, an audible and visual alarm, etc.

[0044] The electrical connection between the alarm component 14 and the acoustic sensor 13 can mean that the acoustic sensor 13 can control the alarm component 14 to sound an alarm; when the acoustic sensor 13 detects air in the pipe 2, the acoustic sensor 13 can send a signal back to the alarm component 14, and the alarm component 14 will sound an alarm upon receiving the signal, thereby reminding personnel that the pipe 2 is not full of water.

[0045] In some examples, the pipe full water monitoring device also includes a controller 15, an acoustic sensor 13, and an alarm component 14, all electrically connected to the controller 15. When the acoustic sensor 13 detects air in the pipe 2, it sends a signal back to the controller 15. Upon receiving the signal, the controller 15 activates the alarm component 14 to sound an alarm, thus alerting personnel that the pipe 2 is not full. The controller 15 can be a PLC controller, etc.

[0046] In this embodiment of the pipe full water monitoring device, the clamping component 12 is clamped outside the pipe 2. The acoustic wave sensor 13 emits sound waves into the pipe 2 and receives the sound waves reflected back from the pipe 2. Since the propagation speed of sound waves in water and air is different, the propagation speed of sound waves in the pipe 2 is different when there is air and when there is no air. By using the speed difference between the two, it can be determined whether the pipe 2 has reached the full water state. When the acoustic wave sensor 13 detects the presence of air in the pipe 2, the acoustic wave sensor 13 feeds back a signal to the alarm component 14, and the alarm component 14 sounds an alarm to remind personnel that the pipe 2 has not reached the full water state. In this way, the full water monitoring of the pipe 2 is realized.

[0047] In some embodiments, the clamping assembly 12 includes a driving component 121 and two clamping members 122. The driving component 121 is connected to the mounting bracket 11, and the two clamping members 122 are respectively connected to opposite sides of the mounting bracket 11. The driving component 121 is connected to the two clamping members 122, and the driving component 121 drives the two clamping members 122 to move closer to each other to clamp the pipe 2.

[0048] The driving component 121 can refer to the component that drives the two clamping members 122 to move closer together. The driving component 121 can be a cylinder or other components.

[0049] The clamping component 122 can refer to a component used to clamp the pipe 2. There are two clamping components 122, which are located on opposite sides of the mounting bracket 11. When clamping, the pipe 2 is located between the two clamping components 122. Under the drive of the driving component 121, the two clamping components 122 move closer to each other, thereby clamping the pipe 2 and fixing the detection unit 1 to the pipe 2.

[0050] By adopting the technical solution of this embodiment, the driving component 121 drives the two clamping components 122 to move closer to each other, thereby clamping the pipe 2. The clamping structure is simple and easy to process and manufacture.

[0051] In some embodiments, the drive component 121 drives the two clamping members 122 to move away from each other, thereby releasing the pipe 2 and disassembling the pipe 2 from the detection unit 1.

[0052] In some embodiments, the driving component 121 includes a driving unit 1211, a connecting block 1212, and two connecting rods 1213. One end of each connecting rod 1213 is hinged to the opposite sides of the connecting block 1212, and the other end of each connecting rod 1213 is hinged to two clamping members 122. The driving unit 1211 is connected to the mounting bracket 11 and the driving unit 1211 is connected to the connecting block 1212 to drive the connecting block 1212 to move, thereby causing the two clamping members 122 to move closer to each other.

[0053] The drive unit 1211 can refer to the component that drives the connecting block 1212 to move. The drive unit 1211 drives the connecting block 1212 to move linearly, thereby driving the two connecting rods 1213 to move, which in turn drives the two clamping members 122 to move closer or further apart.

[0054] The connecting block 1212 is the component that connects the drive unit 1211 and the connecting rod 1213; the connecting rod 1213 is the component that connects the connecting block 1212 and the clamping member 122. One end of the connecting rod 1213 is hinged to the connecting block 1212, and the other end of the connecting rod 1213 is hinged to the clamping member 122. Thus, during the process of the drive unit 1211 driving the connecting block 1212 to move linearly, the two connecting rods 1213 move accordingly and rotate relative to the clamping member 122 and the connecting block 1212, thereby driving the two clamping members 122 to rotate relative to the mounting bracket 11, thereby realizing the relative approach or distance of the two clamping members 122, thereby realizing the clamping and release of the pipe 2.

[0055] "Hinged connection" refers to a connection method in which two components can rotate relative to each other about a specific axis. For example, both components are provided with hinge holes, and a hinge axis passes through the hinge holes of the two components, allowing the two components to rotate relative to each other about the hinge axis.

[0056] In some examples, see Figure 3 As shown, the connecting block 1212 has a receiving groove 12121. The two opposite groove walls of the receiving groove 12121 have hinge holes. One end of the connecting rod 1213 is located in the receiving groove 12121. The connecting rod 1213 is located at the end of the receiving groove 12121. The hinge shaft passes through the hinge hole of the connecting rod 1213 and the hinge hole of the connecting block 1212, thus realizing the hinge connection between the connecting block 1212 and the connecting rod 1213.

[0057] By adopting the technical solution of this embodiment, the driving component 121 adopts the structural form of driving unit 1211, connecting block 1212 and two connecting rods 1213, which has a simple structure and is easy to process and manufacture.

[0058] In some embodiments, the clamping member 122 has a fixing lug 1222 on the side facing away from the pipe 2, and the connecting rod 1213 is hinged to the fixing lug 1222. The hinge structure between the connecting rod 1213 and the clamping member 122 is simple.

[0059] In some examples, the fixed ear 1222 has a receiving groove 12221, and the two opposite groove walls of the receiving groove 12221 have hinge holes. The other end of the connecting rod 1213 is located in the receiving groove 12221, and the end of the connecting rod 1213 located in the receiving groove 12221 has a hinge hole. The hinge shaft passes through the hinge hole of the connecting rod 1213 and the hinge hole of the fixed ear 1222, thus realizing the hinge of the fixed ear 1222 and the connecting rod 1213.

[0060] In some embodiments, the detection unit 1 further includes a connecting plate 16, one end of which is hinged to one end of the clamping member 122, and the other end of which is hinged to the mounting bracket 11.

[0061] The connecting plate 16 can refer to the component used to connect the mounting bracket 11 and the clamping member 122. One end of the connecting plate 16 is hinged to one end of the clamping member 122, and the other end of the connecting plate 16 is hinged to the mounting bracket 11, so that the clamping member 122 can rotate relative to the mounting bracket 11, thereby realizing the clamping and loosening of the pipe 2.

[0062] In some examples, two connecting plates 16 are connected between the mounting bracket 11 and the clamp 122, with the two connecting plates 16 connected to opposite sides of the clamp 122 to improve the reliability of the connection between the mounting bracket 11 and the clamp 122.

[0063] By adopting the technical solution of this embodiment, the two ends of the connecting plate 16 are respectively hinged to the mounting bracket 11 and the clamping member 122, so that the clamping member 122 can rotate in two stages relative to the mounting bracket 11, and the rotation of the clamping member 122 relative to the mounting bracket 11 is more flexible.

[0064] In some embodiments, the drive unit 1211 includes a rotary drive 12111 and a lead screw 12112 connected to the mounting bracket 11. The rotary drive 12111 is connected to the lead screw 12112 and is used to drive the lead screw 12112 to rotate. The connecting block 1212 and the lead screw 12112 are screwed together.

[0065] Rotary drive component 12111 can refer to a component that can output rotational power, such as a motor or electric motor.

[0066] The lead screw 12112 can refer to a rod with external threads on its outer side. The connecting block 1212 has a threaded hole, and the lead screw 12112 passes through the threaded hole, with the external thread meshing with the internal thread in the threaded hole.

[0067] The rotary drive component 12111 is connected to one end of the lead screw 12112, thereby driving the lead screw 12112 to rotate. The rotation of the lead screw 12112 causes the connecting block 1212 to move along the lead screw 12112. The rotary drive component 12111 and the lead screw 12112 can be connected by a coupling or directly fixedly.

[0068] By adopting the technical solution of this embodiment, the rotary drive component 12111 drives the lead screw 12112, and the lead screw 12112 drives the connecting block 1212 to move. Its structure is simple and easy to process and manufacture.

[0069] In some embodiments, the clamping member 122 is an arc-shaped plate adapted to the shape of the pipe 2.

[0070] For example, pipe 2 is a round pipe, and clamping member 122 is an arc plate (i.e., an arc plate), the inner diameter of which is equal to the outer diameter of the round pipe.

[0071] By adopting the technical solution of this embodiment, the arc shape of the arc plate is adapted to the shape of the pipe 2, so that the arc plate can fit better on the outer wall of the pipe 2, and the stability of the two clamping members 122 clamping on the pipe 2 is better.

[0072] In some embodiments, the clamping member 122 is connected to an elastic layer 1221 on the side facing the pipe 2.

[0073] The clamping member 122 has an elastic layer 1221 on its inner side. The elastic layer 1221 can refer to an elastic layered structure, such as a rubber layer or a silicone layer. The elastic layer 1221 can be fixed to the inner side of the clamping member 122 by means of bonding, snap-fitting, or other methods.

[0074] By adopting the technical solution of this embodiment, when the clamping member 122 is clamped on the pipe 2, the elastic layer 1221 is clamped between the pipe 2 and the clamping member 122. The elastic layer 1221 is elastic, which can prevent the clamping member 122 from making direct hard contact with the pipe 2 and reduce damage to the pipe 2.

[0075] In some embodiments, the mounting bracket 11 has a first wall 111 and a mounting cavity 112 for accommodating the acoustic sensor 13 and the drive unit 1211. The first wall 111 is located between the mounting cavity 112 and the pipe 2, and the acoustic sensor 13 is embedded in the first wall 111.

[0076] The mounting bracket 11 is hollow inside, and the internal cavity of the mounting bracket 11 forms a mounting cavity 112, which provides mounting space for the drive unit 1211 and the acoustic sensor 13.

[0077] The first wall 111 can refer to the side wall of the mounting bracket 11 located between the mounting cavity 112 and the pipe 2.

[0078] For example, the first wall 111 refers to the cavity wall of the mounting cavity 112 near the pipe 2.

[0079] For example, the mounting bracket 11 includes a housing 116 and a connecting plate 117, with the inner cavity of the housing 116 forming a mounting cavity 112. The connecting plate 117 is located between the housing 116 and the pipe 2, and the connecting plate 117 is connected to the side wall of the housing 116 near the connecting plate 117 to form a first wall 111. The connecting plate 117 and the housing 116 can be integrally formed or separately formed and then assembled together.

[0080] The acoustic sensor 13 is embedded in the first wall 111. It is understood that the first wall 111 has a mounting hole, and the acoustic sensor 13 is installed in the mounting hole.

[0081] In some examples, the mounting hole can be a through hole, so that the acoustic sensor 13 can pass through the first wall 111. There are no obstacles between the acoustic sensor 13 and the pipe 2, and the sound waves emitted by the acoustic sensor 13 can be directly transmitted to the pipe 2, which helps to reduce interference and improve the accuracy of monitoring.

[0082] In some examples, mounting holes may also be blind holes.

[0083] By adopting the technical solution of this embodiment, the drive unit 1211 and the acoustic sensor 13 are located in the mounting cavity 112. The mounting bracket 11 can protect the drive unit 1211 and the acoustic sensor 13, which is beneficial to improving the reliability of the detection unit 1. The first wall 111 is located between the mounting cavity 112 and the pipe 2. The acoustic sensor 13 is embedded in the first wall 111. The first wall 111 is set close to the pipe 2, and the acoustic sensor 13 is also set close to the pipe 2, which is beneficial to reduce the obstruction of the sound wave to the pipe 2 and improve the accuracy of monitoring.

[0084] In some embodiments, the mounting bracket 11 is provided with a first partition 113, which is located in the mounting cavity 112. The first partition 113 divides the mounting cavity 112 into a first chamber 1121 and a second chamber 1122. The first chamber 1121 is located between the first wall 111 and the second chamber 1122. The acoustic sensor 13 is located in the first chamber 1121, and the driving unit 1211 is located in the second chamber 1122.

[0085] The first partition 113 divides the mounting cavity 112 into two independent chambers. The chamber closer to the pipe 2 is the first chamber 1121, and the chamber farther from the pipe 2 is the second chamber 1122. The acoustic sensor 13 is located in the first chamber 1121, and the drive unit 1211 is located in the second chamber 1122. This arrangement of the acoustic sensor 13 and the drive unit 1211 in two independent chambers reduces mutual interference and improves monitoring accuracy. The first chamber 1121 is located between the first wall 111 and the second chamber 1122. The acoustic sensor 13 is relatively close to the pipe 2, which helps reduce the obstruction of sound waves into the pipe 2 and improves monitoring accuracy.

[0086] In some embodiments, see Figure 4As shown, a second partition 115 is provided in the second chamber 1122, which divides the second chamber 1122 into a first half-chamber 11221 and a second half-chamber 11222. The first half-chamber 11221 is located between the second half-chamber 11222 and the first chamber 1121. The lead screw 12112 and the connecting block 1212 are located in the first half-chamber 11221, and the rotary drive component 12111 is located in the second half-chamber 11222. The second half-chamber 11222 is a closed cavity to protect the rotary drive component 12111. The first half-chamber 11221 is a cavity with openings on both sides to facilitate the connection of the connecting block 1212 with the two connecting rods 1213.

[0087] In some embodiments, the first chamber 1121 may be a closed chamber or a chamber with openings on both sides.

[0088] In some embodiments, the first wall 111 is an arc-shaped wall for fitting with the pipe 2. Two clamping members 122 are connected to opposite sides of the arc-shaped wall along the arc-shaped extension direction. The two clamping members 122 and the first wall 111 can form an arc structure that can be adapted to the shape of the pipe 2 to fit on the pipe wall of the pipe 2.

[0089] In some embodiments, the mounting bracket 11 is provided with a handle 114.

[0090] For example, the mounting bracket 11 has a handle 114 on the side facing away from the pipe 2. Of course, the handle 114 can also be provided in other positions on the mounting bracket 11.

[0091] By adopting the technical solution of this embodiment, the handle 114 can be held by personnel to facilitate the carrying of the detection unit 1.

[0092] In some embodiments, the pipeline full water monitoring device includes a power supply for powering the detection unit 1.

[0093] In this embodiment of the pipeline full-water monitoring device, several detection units 1 are connected to a power source. The detection units 1 are then placed at the top of the pipeline 2 every ten meters. The rotary drive 12111 is controlled to rotate the lead screw 12112. The rotation of the lead screw 12112 causes the connecting block 1212 to descend. The descent of the connecting block 1212 causes two connecting rods 1213 to descend, causing two clamping members 122 to move closer together and clamp the pipeline 2, thus fixing the detection units 1. The full-water status of the pipeline 2 is then detected by an acoustic sensor 13. The sound wave sensor 13 emits a sound wave into the pipe 2, and then receives the reflected sound wave through the receiver of the sound wave sensor 13. The sound wave travels faster in water than in air. When there is air at the top of the pipe 2, the time it takes for the receiver of the sound wave sensor 13 to receive the reflected sound wave becomes longer. At this time, the sound wave sensor 13 sends the detection result to the controller 15. The controller 15 then controls the alarm component 14 to issue an alarm, thereby reminding the staff that the pipe 2 is not full of water. A detection unit 1 is set at certain intervals in the pipe 2 to ensure the continuity of detection.
