[0040] Referring to Figures 2 to 9 Suspension power generation monitoring device 100 includes first suspension and stabilizing assembly 1, monitoring assembly 2, electromagnetic signal emitter 3, first stabilizing auxiliary 4 and first auxiliary suspension and power generation assembly 5.

[0041] Specifically, referring to Figure 4 First suspension and stabilizing assembly 1 includes suspension shell 11, first gas generating device 12, first floating air bag 14 and first inflatable stabilizing air bag 15. Wherein, first gas generating device 12 and first floating air bag 14 are arranged in suspension shell 11, and first inflatable stabilizing air bag 15 is three, three first inflatable stabilizing air bag 15 is evenly distributed on the outer wall of suspension shell 11 along the circumference. First gas generating device 12 and the inlet of first floating air bag 14 are provided with first switch valve 13 for realizing the on-off of pipeline between them. First exhaust passage 16 is also provided at the exhaust port of first floating air bag 14, and a third switch valve 17 is arranged on the pipeline between them for controlling the on-off of pipeline.

At the same time, the module contains a passage for absorbing gas, which separates gas and liquid, and the gas is introduced into first floating air bag 14 by first gas generating device 12. Thus, first suspension and stabilizing assembly 1 can electrolyze the water in PCCP pipe and introduce the generated gas into first inflatable stabilizing air bag 15 through first floating air bag 14, so that the sustained monitoring device is inflated and fixed in PCCP, and prepares for subsequent power generation. It should be noted that the number of first gas generating device 12 and first switch valve 13 can be multiple, for example, two, two first gas generating device 12 is arranged symmetrically. In addition, the specific number of first gas generating device 12 and first switch valve 13 is selected according to actual working condition, which is not limited here.

[0043] Referring toFigure 2 and Figure 3 The monitoring assembly 2 comprises a monitoring ring 21 arranged at the head of the floating shell 11 and a directional monitoring and sensor 22. The monitoring ring 21 is capable of scanning the PCCP pipe (detecting the corrosion of the inner wall and the broken wires of the prestressed steel wire layer) and sending the scanning result to the electromagnetic signal transmitter. Specifically, the monitoring ring 21 is a ring-shaped probe group formed by a plurality of ultrasonic flaw detection probes. The directional monitoring and sensor 22 is capable of detecting the water flow condition in the PCCP pipe.

[0044] The electromagnetic signal transmitter 3 is capable of sending the scanning result of the PCCP pipe to the signal floating power generation transmission device group 2 and sending the water flow condition signal to the first auxiliary floating and power generation assembly 5.

[0045] Referring to Figures 7 to 9 The first stabilizing auxiliary 4 comprises a stabilizing auxiliary shell 41 and a motor with a brake 42, a gyroscope module (not shown in the figure), a rotating shaft 43 and a counterweight 44 arranged in the stabilizing auxiliary shell 41. The electromagnetic signal transmitter 3 is also integrated in the stabilizing auxiliary shell 41. The stabilizing auxiliary shell 41 comprises a streamlined shell 411 and a cover plate 412 connected to the end of the streamlined shell 411. The gyroscope module is connected to and in communication connection with the motor with a brake 42. The motor with a brake 42 is also in electrical connection with the first auxiliary floating and power generation assembly 5, which is capable of supplying power to the motor with a brake 42. The fixed end of the motor with a brake 42 is connected to the cover plate 412, and the output end is connected to the rotating shaft 43 through a counterweight and rotating shaft connector 45. The counterweight 44 is fixedly connected to the rotating shaft 43 and is in sliding connection with the streamlined shell 411 through a counterweight ring stabilizer 46. In this way, the gyroscope module is capable of controlling the rotation of the motor with a brake 42 according to the water flow condition, so as to change the ring-shaped counterweight distribution and adjust the rotation of the whole device. In addition, in order to make the motor with a brake 42 more reliable, the stabilizing auxiliary shell 41 is further provided with a limit stop 47, four connecting columns 48 and a stabilizer 49. Specifically, the limit stop 47 is sleeved on the rotating shaft 43, the outside of the limit stop 47 is fixedly connected to the stabilizer 49, and the stabilizer 49 is connected to the cover plate 412 through the four connecting columns 48.

[0046] Referring to Figures 2 to 5The first auxiliary suspension and power generation assembly 5 comprises a motor 51, a water wheel 52, a control unit (not shown in the figure), an electric energy storage device (not shown in the figure) and an electric quantity detection unit (not shown in the figure). The motor 51 is a motor-generator, for example, a motor of model E-936-AX-IV, and the motor needs to be waterproofed. The motor 51 is fixed between the suspension shell 11 and the first stable auxiliary device 4, and the water wheel 52 is connected to the output shaft of the motor 51. It should be noted that the motor 51 and the water wheel 52 can also be multiple. The control unit, the electric energy storage device and the electric quantity detection unit are all arranged in the first stable auxiliary device, and the control unit is in communication connection with the motor and the directivity monitoring and sensor. The control unit can receive the water flow condition signal sent by the directivity monitoring and sensor, and control the motor 51 to start and stop according to the water flow condition signal. The electric energy storage device can store the electric energy generated by the motor 51. Specifically, the electric energy storage device can adopt a battery. The electric quantity detection unit is in communication connection with the battery and the motor 51. When the electric quantity detection unit detects that the battery has sufficient electric quantity, the electric quantity detection unit controls the motor 51 to drive the water wheel 52 to rotate as a motor, so that the suspension power generation monitoring device 100 can remain stable in the flowing water; and when the electric quantity detection unit detects that the battery has insufficient electric quantity, the electric quantity detection unit controls the motor 51 to generate electricity as a generator, drives the motor 51 to generate electricity through the water flow impacting the water wheel 52, and stores the obtained electric energy into the battery for use of the first suspension and stable assembly 1, the monitoring assembly 2 and the first stable auxiliary device 4.

[0047] With reference to Figure 1 The signal suspension power generation transmission device group 200 comprises a plurality of signal suspension power generation transmission devices 6 arranged in sequence along the axis of the PCCP pipe. With reference to Figure 10 and Figure 11 The signal suspension power generation transmission device 6 comprises a shell 7, a second suspension and stable assembly 8, a second auxiliary suspension and power generation assembly 9, two second stable auxiliary devices 10 and an electromagnetic signal transmitter (not shown in the figure).

[0048] The second suspension and stable assembly 8 has the same structure as the first suspension and stable assembly 1. The second suspension and stable assembly 8 comprises a plurality of second gas generating devices 81, a second floating air bag 82, a plurality of fifth switch valves (not shown in the figure), a plurality of second inflation stable air bags 83, a sixth switch valve (not shown in the figure) and a second exhaust passage (not shown in the figure). In some embodiments, the number of second gas generating devices 81 and fifth switch valves is four, and the number of second inflation stable air bags 83 is two. The four second gas generating devices 81 are arranged in pairs symmetrically above and below, and the two second inflation stable air bags 83 are connected symmetrically left and right outside the shell 7. It should be noted that the specific number of second gas generating devices 81, fifth switch valves and second inflation stable air bags 83 is selected according to actual working conditions and is not limited here.

[0049] The structure of the second gas generating device 81 is the same as that of the first gas generating device 12, and the inlet thereof is communicated with the liquid, and the outlet thereof is communicated with the inlet of the second floating air bag 82, and the outlet of the second floating air bag 82 is communicated with the second inflation stabilizing air bag 83. The second floating air bag 82 has the same structure as the first floating air bag 14; and the fifth switch valve has the same structure as the first switch valve 13. The second gas generating device 81 and the second floating air bag 82 are both located in the shell 7.

[0050] The sixth switch valve is arranged on the pipeline between the second floating air bag 82 and the second exhaust passage, and is used for controlling the opening and closing of the pipeline therebetween. Thus, after the fifth switch valve is opened, the second suspension and stabilizing assembly 8 can make the continuous monitoring device expand and be clamped in the PCCP, and prepare for the subsequent power generation. After the sixth switch valve is opened, the gas in the second inflation stabilizing air bag 83 is exhausted through the second floating air bag 82 and the second exhaust passage.

[0051] The second auxiliary suspension and power generation assembly 9 is similar to the first auxiliary suspension and power generation assembly 5 in structure, and the difference is that the control unit in the second auxiliary suspension and power generation assembly 9 is in communication connection with the motor and the electromagnetic signal transmitter, and the control unit can control the start and stop of the motor according to the received signal strength, so as to adjust the distance between the signal suspension power generation transmission device 6 and the suspension power generation monitoring device 100.

[0052] The two second stabilizing assistants 10 are connected at two ends of the shell 7. The second stabilizing assistant 10 has the same structure as the first stabilizing assistant 4.

[0053] Thus, the signal suspension power generation transmission device 6 located at the front end can receive the scanning signal of the PCCP pipe transmitted by the suspension power generation monitoring device 1, and transmit the signal to the adjacent signal suspension power generation transmission device; the signal suspension power generation transmission device 6 located at the middle part can receive the scanning signal of the PCCP pipe transmitted by the signal suspension power generation transmission device 6 at the front side, and transmit the signal to the signal suspension power generation transmission device at the rear side; and the signal suspension power generation transmission device 6 located at the tail end can receive the scanning signal of the PCCP pipe transmitted by the signal suspension power generation transmission device 6 at the front side, and transmit the signal to the external information receiving and analyzing end.

[0054] The working principle of the long-distance water conveying PCCP pipe continuous monitoring device according to the embodiment of the present application is as follows:

[0055] Before detection, the first switch valve 13 and the second switch valve 122 are opened, and the first floating air bag 14 is directly inflated, and after being filled with gas, the first switch valve 13 and the second switch valve 122 are closed. Then, the second floating air bag 14 is filled with gas in the same way. Then, the suspension power generation monitoring device 100 and the plurality of signal suspension power generation transmission devices 6 are all placed in the PCCP pipe to be detected.

[0056] When in the monitoring phase (i.e. when the power detection unit detects that the power storage device in the suspended power generation monitoring device 100 is in a sufficient power state), the motor 51 in the first auxiliary suspension and power generation assembly 5 is controlled to switch to the electric motor state, the motor 51 drives the water wheel 52 to rotate, ensuring that the suspended power generation monitoring device 100 can maintain a certain stability in the moving water flow in the PCCP pipe, so that the suspended power generation monitoring device 100 floats in the full water PCCP pipe by buoyancy, and adjusts its posture inside the pipe by the first stable auxiliary device 4 as needed, deflects the whole body, so that the monitoring ring 21 can fully contact and scan the inner wall of the PCCP pipe to be measured, and then the electromagnetic signal transmitter 3 sends the scanning result to the signal suspended power generation transmission device 6. At the same time, the directional monitoring and sensor 22 detects the flow of water and feeds back the detection result to the control unit, which controls the start and stop of the motor 51 according to the flow of water, forming a closed loop.

[0057] When in the charging phase (i.e. when the power detection unit detects that the power storage device in the suspended power generation monitoring device 100 is in a insufficient power state), the second switch valve 122 is opened to make water enter the first gas generating device 12, and then the second switch valve 122 is closed. The first gas generating device 12 electrolyzes the water in the PCCP pipe, and after the gas is generated, the first switch valve 13 is opened, so that the gas generated by the first gas generating device 12 enters the first inflatable stabilizing air bag 15 through the first floating air bag 14. The first inflatable stabilizing air bag 15 is inflated, so that the suspended power generation monitoring device 100 is inflated and clamped in the PCCP. It should be noted that the gas generated in the process of electrolyzing water can smoothly enter the air bag due to the increase in gas pressure. In addition, during the inflation process, the posture of the suspended power generation monitoring device 100 is adjusted by controlling the motor 51 and the first stable auxiliary device 4, so that the gas can smoothly enter the air bag.

[0058] After the suspended power generation monitoring device 100 is clamped in the PCCP, the motor 51 is controlled to switch to the generator state, and the first inflatable stabilizing air bag 15 and the water wheel 52 rotate under the impact of the water flow in the PCCP pipe, and drive the motor 51 to generate electricity. The obtained electric energy is stored in the battery for use by the first suspension and stabilizing assembly 1, the monitoring assembly 2, and the first stable auxiliary device 4. After charging is completed, the third switch valve 17 is opened, and the gas in the first inflatable stabilizing air bag 15 is discharged, and the suspended power generation monitoring device 100 is separated from the pipe wall. It should be noted that the first inflatable stabilizing air bag 15 is extruded due to the impact of the water flow, and the material of the first inflatable stabilizing air bag 15 itself is elastic, so that the gas can be smoothly discharged without the need to set up an external air extraction mechanism.

[0059] After the signal suspended power generation transmission device 6 is put into the PCCP pipe, the motor in the second auxiliary suspended power generation assembly 9 starts to work, driving the water wheel to move, so that the signal suspended power generation transmission device 6 can be in the water flow relatively stable. At the same time, the gas generated by the second gas generating device 81 in the second suspended and stable assembly 8 enters the second floating air bag 82 for storage. Thus, the signal suspended power generation transmission device 6 is floated in the full water PCCP pipe by the buoyancy. When in the state of insufficient power, the fifth switch valve and the switch valve in the second gas generating device 81 are opened, the second gas generating device 81 inflates the second inflatable stable air bag 83 through the second floating air bag 82, so that the second inflatable stable air bag 83 is inflated, so that the signal suspended power generation transmission device 6 is expanded and clamped in the PCCP. Then, the second auxiliary suspended power generation assembly 9 starts to generate electricity, and the working principle is the same as that of the first suspended and stable assembly 5, which will not be described here. In summary, the signal suspended power generation device is similar to the function of the signal repeater, and multiple signal suspended power generation transmission devices 6 work together to transmit the signal of the frontmost suspended power generation monitoring device 100 out of the PCCP pipe.

[0060] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
