[0031] A pressure pipeline detection device of the present invention determines whether the liquid is turbid by detecting the intensity of the red light source based on the different abilities of the red light source to penetrate liquids of different turbidity levels, and can simultaneously detect the original liquid state inside the pressure pipeline and the state after the liquid and sediment are mixed.

[0049] Example 1, please refer to the attached manual Figure 1-6 The present invention provides a technical solution: a pressure pipeline detection device, comprising:

[0050] The detection mechanism 1 moves in the pressure pipeline 2 and can simultaneously detect cracks on the inner wall of the pressure pipeline 2 and turbidity of the liquid inside the pressure pipeline 2, thereby solving the problem that conventional pressure pipeline detection equipment can only detect cracks in the pipeline and has a small scope of application.

[0051] The testing organization 1 includes:

[0052] A power housing 111, wherein a working chamber 126 for storing lithium batteries is disposed inside the power housing 111, an inlet channel 124 is disposed at one end of the power housing 111, one end of the inlet channel 124 penetrates the end surface of the power housing 111, and the other end is communicated with the first channel 122, an end of the first channel 122 away from the inlet channel 124 is inclined downward and penetrates the outer ring surface of the power housing 111, and a second channel 123 is disposed at the other end of the power housing 111, one end of the second channel 123 penetrates the end surface of the power housing 111, and the other end penetrates the outer ring surface of the power housing 111, and a circulation channel is formed in sequence between the inlet channel 124, the first channel 122 and the second channel 123 for liquid to enter from the inlet channel 124 at one end of the power housing 111 and to be discharged to the other end of the power housing 111 after passing through the first channel 122, the outer ring of the power housing 111 and the second channel 123 in sequence;

[0053] Among them, a turbine device 125 for driving the flow of liquid is arranged inside the inlet channel 124. The turbine device 125 uses a conventional turbine and a motor, which is the existing technology and will not be described in detail here.

[0054] The detection housing 112 is an annular structure. Two detection housings 112 are provided. The two detection housings 112 are detachably provided at both ends of the power housing 111. The annular channel in the middle of one detection housing 112 corresponds to the end of the entrance channel 124 away from the first channel 122, and the annular channel in the middle of the other detection housing 112 corresponds to the position where the second channel 123 penetrates the end surface of the power housing 111;

[0055] Among them, the interior of the detection shell 112 is hollow, and a red spotlight 127, a photosensitive sensor 128, a camera 129 and an ultrasonic detector 130 are installed in the hollow. The red spotlight 127 is used to emit a red light source, and the photosensitive sensor 128 is used to receive a red light source. The red spotlight 127 and the photosensitive sensor 128 are arranged opposite to each other. An inner circle glass window 120 is installed on the inner wall of the annular structure of the detection shell 112. The red light source emitted by the red spotlight 127 passes through the inner circle glass window 120 and is received by the photosensitive sensor 128. The turbidity of the liquid inside the pressure pipe 2 is judged by the intensity of the red light source received by the photosensitive sensor 128. The stronger the intensity of the red light source, the stronger the ability of the red light source to penetrate the liquid, thereby proving that the liquid is relatively clear; if the liquid is relatively turbid, the ability of the red light source to penetrate the liquid is relatively weak, and finally the intensity of the red light source received by the photosensitive sensor 128 is relatively small; therefore, in the present invention, based on the different abilities of the red light source to penetrate liquids of different turbidities, it is realized by detecting the intensity of the red light source to judge whether the liquid is turbid.

[0056] When the intensity of the red light source received by the photosensor 128 drops to a certain threshold, it is determined that the turbidity of the liquid inside the pressure pipe 2 is too high and needs to be processed. The specific detection threshold can be determined according to production requirements and will not be elaborated here.

[0057] When the turbine device 125 is started, suction is generated, and the liquid enters from the inlet channel 124 at one end of the power housing 111 and passes through the first channel 122, the outer ring of the power housing 111, and the second channel 123 in sequence, and then is discharged to the other end of the power housing 111; it is worth noting that when the liquid passes through the middle of a detection housing 112 near the inlet channel 124, the turbidity is detected by the photosensitive sensor 128 there, and the turbidity of the liquid at this time is the original turbidity of the liquid inside the pressure pipe 2; when the liquid discharged from the turbine device 125 rushes to the inner wall of the pressure pipe 2 and is reflected by the inner wall of the pressure pipe 2 and enters the second channel 123, the liquid can drive the sediment accumulated on the bottom surface of the pressure pipe 2 to rise, so that a photosensitive sensor 128 near the second channel 123 detects the mixing degree of the liquid and sediment inside the pressure pipe 2 when they are mixed; if the turbidity data before and after the power housing 111 deviates too much, it proves that there are a lot of sediments on the bottom surface of the pressure pipe 2, which needs to be cleaned in time, otherwise it will affect the transmission efficiency of the pressure pipe 2 to the liquid and affect the quality of the liquid.

[0058] The present invention provides a flow channel with a reasonable trajectory, so that when the liquid circulates, it can generate power to push the detection mechanism 1 to move without affecting the detection of the turbidity degree of the liquid, replacing the setting of the turbine power device in the prior art that directly mixes the liquid and sediment inside the pressure pipe 2.

[0059] In the present invention, the red spotlight 127, the photosensor 128, the camera 129 and the ultrasonic detector 130 are all arranged in the hollow part inside the detection shell 112, and can operate in the liquid without being affected by the liquid and pressure. In particular, it solves the problem in the prior art that the photosensor 128 cannot work in the liquid and the pressure change may affect the band gap width of the material, thereby affecting the generation of photogenerated electron-hole pairs.

[0060] The camera 129 is used to capture images of the liquid inside the pressure pipe 2. An end glass window 119 for the camera 129 to capture is provided on one side of the detection housing 112 away from the power housing 111. The two cameras 129 are respectively used to capture images of the original state of the liquid inside the pressure pipe 2 and images of the state after the liquid and sediment are mixed, for easy comparative observation.

[0061] The ultrasonic detector 130 is used to detect whether there are cracks on the inner wall of the pressure pipe 2. The ultrasonic detector 130 uses ultrasonic emission to measure the measured distance through the reflection of the measured object and the time difference after the echo is received. When detecting whether there are cracks on the inner wall of the pressure pipe 2, the sound wave will be reflected at the defect, and the reflected ultrasonic wave is received by the ultrasonic detector 130. By analyzing the characteristics of the reflected wave and the time difference, the existence, location and nature of the defect can be determined.

[0062] During specific use, four ultrasonic detectors 130 are provided, and the four ultrasonic detectors 130 are distributed at equal angles around the axis of the detection shell 112 , so as to facilitate the detection of whether cracks appear on the inner wall of the pressure pipe 2 .

[0063] It should also be noted that reserved holes are provided inside the power housing 111 for the wiring of the lithium battery, controller, and wireless transmission device inside the working chamber 126 to pass through. Although not shown in the figure, this is a conventional setting that can be easily arranged by technicians in this field according to the specific installation position of the parts and will not be elaborated here.

[0064] The controller is the core component. The data detected by the ultrasonic detector 130, the images captured by the camera 129 and the data detected by the photosensitive sensor 128 are all fed back to the controller. The controller transmits the corresponding data information to the terminal server via a wireless transmission device in 5G or 4G mode. The remote server can obtain and record the corresponding data, which is practical and convenient.

[0065] When the data is abnormal, the server will alarm and send staff to handle it in time.

[0066] In order to ensure that the detection mechanism 1 can move normally in the pressure pipe 2 without being affected by the bends or defects of the pipe and getting stuck, a mounting groove 118 is provided at the outer ring of the power housing 111, and a guide rod 113 is provided in the mounting groove 118. One end of the guide rod 113 is rotatably connected to the inner wall of the mounting groove 118, and a guide wheel 117 is rotatably provided at the other end of the guide rod 113, and a spring 116 is fixedly provided between the guide rod 113 and the mounting groove 118; four guide rods 113 are provided, and the four guide rods 113 are distributed at equal angles around the axis of the power housing 111; when the detection mechanism 1 moves inside the pressure pipe 2, the spring 116 elastically supports the guide rod 113, so that the guide wheel 117 at the end of the guide rod 113 is always attached to the inner wall of the pressure pipe 2, and the four guide wheels 117 are evenly attached to the inner wall of the pressure pipe 2 around a circle, which provides the detection mechanism 1 with basic guidance and adaptability, so that the detection mechanism 1 can move smoothly in the pressure pipe 2, so as to pass through the bends and defects of the pressure pipe 2.

[0067] In the specific configuration, the diameter of the power housing 111 is smaller than the diameter of the pressure pipe 2 , thereby ensuring that the detection mechanism 1 can smoothly pass through the bend of the pressure pipe 2 .

[0068] Considering that if there are more impurities in the liquid inside the pressure pipe 2, it is easy to affect the turbine device 125, or even block the turbine device 125, making the turbine device 125 unable to work normally, a filter 121 is also installed at the end of the entrance channel 124 away from the first channel 122. The filter 121 filters the liquid entering the entrance channel 124 and the turbine device 125, ensuring that the liquid can pass through the entrance channel 124 and the turbine device 125 smoothly.

[0069] In actual use, a connecting rod 115 is fixedly provided on one side of the detection shell 112 close to the power shell 111, and a groove 114 is provided on the power shell 111, and the connecting rod 115 is fixed in the groove 114 by screws; disassembly and maintenance are convenient, and a gap for liquid circulation is provided between the detection shell 112 and the power shell 111, thereby ensuring smooth circulation of liquid, rather than just entering through the middle of the detection shell 112. When the liquid is sucked into the gap between the detection shell 112 and the power shell 111, the pressure of the liquid at the outer circle of the power shell 111 can be reduced, thereby reducing resistance and ensuring sufficient power.

[0070] The detection mechanism 1 in the present invention is suitable for a pressure pipe 2, and a plurality of auxiliary pipes 20 are arranged at equal distances on the pressure pipe 2, the auxiliary pipes 20 are connected to the upper surface of the pressure pipe 2, and the diameter of the auxiliary pipe 20 is larger than the diameter of the pressure pipe 2; a sealing block 204 is arranged in the auxiliary pipe 20 so as to be liftable, and one end of the sealing block 204 has an arc-shaped guide surface 205; when the sealing block 204 descends and fits against the inner bottom surface of the pressure pipe 2, the pressure pipe 2 is cut off, and the detection mechanism 1 in the moving process can enter the auxiliary pipe 20 along the arc-shaped guide surface 205, so as to achieve the purpose of recovering the detection mechanism 1 and facilitate the maintenance and charging of the detection mechanism 1; when the sealing block 204 rises and is flush with the bottom of the auxiliary pipe 20, the pressure pipe 2 and the auxiliary pipe 20 are separated; the liquid with a certain pressure in the pressure pipe 2 is prevented from entering the auxiliary pipe 20, and at this time, the upper end of the auxiliary pipe 20 is opened and the sealing cover 201 is arranged so as to smoothly take out the detection mechanism 1 without discharging the liquid in the pressure pipe 2.

[0071] Furthermore, the sealing cover 201 is connected to the opening at the upper end of the auxiliary pipe 20 by threaded fitting, and can be opened or installed by rotating operation, which is simple and convenient to operate.

[0072] It is worth mentioning that when the detection mechanism 1 moves in the pressure pipe 2, it can also push out obvious impurities in the pressure pipe 2. When the opening above the auxiliary pipe 20 is opened, the impurities and the detection mechanism 1 can be taken out together, which has a certain unblocking effect on the pressure pipe 2.

[0073] In the present invention, a fixed base 202 is fixedly provided on the inner wall of the auxiliary pipe 20, and a waterproof electric cylinder 203 is fixedly provided on the bottom surface of the fixed base 202. The waterproof electric cylinder 203 is vertically arranged, and the telescopic end of the waterproof electric cylinder 203 is fixedly connected to the blocking block 204. When the waterproof electric cylinder 203 is started, the blocking block 204 can be pushed up and down, and the operation is simple and convenient.

[0074] It should be noted that the parts where the auxiliary pipe 20 and the pressure pipe 2 are connected are square pipes, which are convenient for isolating the pressure pipe 2 or the auxiliary pipe 20 when the blocking block 204 is raised or lowered. Pipes of other suitable shapes can also be used and set according to actual needs. The joint between the square pipe and the pressure pipe 2 requires an arc chamfer to facilitate the passage of the detection mechanism 1, which will not be elaborated here.

[0075] In Example 2, please refer to the attached Figure 1-7 Considering that the detection mechanism 1 may change direction due to the obstruction of sediment or cracks on the inner wall of the pressure pipe 2 when moving in the pressure pipe 2, the present invention provides a plurality of first channels 122 and a plurality of second channels 123, and the plurality of first channels 122 correspond to the plurality of second channels 123 one by one, and the plurality of first channels 122 are connected to the entry channel 124, and the plurality of first channels 122 are distributed at equal angles around the axis of the power housing 111. When the liquid is discharged from the first channel 122, it can evenly impact the inner wall of the pressure pipe 2, and the liquid then enters from the corresponding second channel 123 and passes through the middle of a detection housing 112 close to the second channel 123, thereby avoiding the phenomenon that the liquid discharge position is difficult to control when only one first channel 122 and one second channel 123 are provided.

[0076] In actual use, due to the different resistances at different positions inside the pressure pipe 2, the liquid thrust discharged from the multiple first channels 122 and the multiple second channels 123 will push the power housing 111 to rotate, thereby achieving the purpose of spiral movement of the power housing 111, which can not only reduce resistance, but also cause most of the sediment at the bottom of the pressure pipe 2 to be lifted up, thereby improving the detection results and avoiding the formation of stubborn stains on the inner wall of the pressure pipe 2.

[0077] It should be noted that the first channel 122 and the second channel 123 may also be arranged to be inclined relative to the axial cross section of the power housing 111 , which can further increase the effect of the power housing 111 advancing spirally in the pressure pipe 2 .

[0078] When the power housing 111 spirally moves forward in the pressure pipe 2 , the dredging effect on the pressure pipe 2 is also increased.
