[0015] A detection method for a water diversion pipeline leakage detection device comprises the following steps:

[0016] S1. Install the connecting flanges of multiple adjacent water diversion pipe bodies together. When in use, install the pointer pressure gauge in the fixed sleeve. When the water diversion pipe body leaks, its internal pressure will change. When inspecting, the staff can determine whether there is a leak inside the water diversion pipe body by observing whether the reading of the pointer pressure gauge is stable. The guided water will flow through the connecting pipe and the metal tube rotor flowmeter. Under normal use, when there is no leakage in the water diversion pipe body, the flow rate measured by the metal tube rotor flowmeter will not change significantly. When the water diversion pipe body leaks, water will leak out of the leaking point, and the water flow rate through the metal tube rotor flowmeter will change. The inspector can also determine whether there is a leak in the water diversion pipe body by observing the numerical display of the metal tube rotor flowmeter.

[0017] S2. Wrap the color ring around the outside of the two connecting flanges. The color ring is made of liquid-permeable fabric. Apply a water indicator to the inner and outer surfaces of the color ring. When a leak occurs at the connection between the two connecting flanges, the water indicator will change color.

The camera can record the color development situation.

[0019] S4. By starting the multi-stage electric push rod, the multi-stage electric push rod is extended and retracted, thereby driving the slide plate to slide back and forth on the slide rod. At this time, the infrared thermal imager is in the turned-on state. The slide plate will drive the infrared thermal imager to scan the surface of the water diversion pipe body to detect whether there is a leak.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When in use, the color ring is made of cloth that can be penetrated by liquids, and a water indicator is applied to the inner and outer surfaces of the color ring. When a leak occurs at the connection between the two connecting flanges, the color of the water indicator will change. The extent of the leak can be judged based on the area and speed of the color change of the color ring. When the color ring is installed, the transparent protective cover is put on the outside of the color ring. At this time, each sealing strip is tightly attached to the water pipe body, which can keep the transparent protective cover in a sealed state, thereby effectively preventing external moisture from entering the transparent protective cover and interfering with the color development of the color ring. By starting the camera, the two cameras monitor the surface of the color ring in all directions. When the color ring shows color, the controller receives an abnormal signal and controls the activation of the alarm to sound an alarm, reminding the inspector of the leak and making further inspection and repairs on the leak. The camera can record the color development.

[0022] 2. When in use, by starting the multi-stage electric push rod, the multi-stage electric push rod is extended and retracted, thereby driving the slide plate to slide back and forth on the slide rod. By turning on the infrared thermal imager and putting the infrared thermal imager into scanning state, the slide plate will drive the infrared thermal imager to scan the surface of the water diversion pipe body. By detecting the temperature abnormality at the leak point, the degree of leakage can be judged, which can prevent misjudgment during manual inspection;

[0023] 3. During use, when the water diversion pipe body leaks, its internal pressure will change. When inspecting, the staff can judge whether there is a leak inside the water diversion pipe body by observing whether the reading of the pointer pressure gauge is stable. In addition, the guided water flow will flow through the connecting pipe and the metal tube rotor flowmeter. Under normal use, when the water diversion pipe body does not leak, the flow rate measured by the metal tube rotor flowmeter will not change significantly. When the water diversion pipe body leaks, water will leak out of the leak, and the speed of the water flow through the metal tube rotor flowmeter will change. The inspector can also judge whether there is a leak in the water diversion pipe body by observing the numerical display of the metal tube rotor flowmeter. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of each sealing groove 504 is pasted with a sealing strip 503. When sleeved, the transparent protective cover 501 is sleeved on the outside of the color-developing ring 502. At this time, each sealing strip 503 is tightly attached to the water diversion pipe body 1, which can make the transparent protective cover 501 in a sealed state, thereby effectively preventing external moisture from entering the transparent protective cover 501 and interfering with the color-developing effect of the color-developing ring 502.

[0040] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, every two fixing rings 601 are symmetrically arranged, and a rotating plate 602 is welded at one end of each fixing ring 601. Every two rotating plates 602 are connected to each other by a hinge, and a reinforcing block 603 is welded between the outer surface of each rotating plate 602 and the outer surface of each fixing ring 601. The triangular structure of the reinforcing block 603 strengthens the fixing ring 601, so that the fixing ring 601 can be made firm.

[0041] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the outer surfaces of multiple fixing rings 601 are fixed with U-shaped fixing rods 608, and one end of the multiple U-shaped fixing rods 608 is fixedly connected to the outer surfaces of another multiple fixing rings 601. By taking two U-shaped fixing rods 608, the fixing rings 601 connected by the two U-shaped fixing rods 608 can be rotated and sleeved on the outer surface of the water diversion pipe body 1.

[0042] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the other end of each fixing ring 601 is fixedly connected to a reinforcement block 606, and a fixing hole 612 is opened on the outer surface of each reinforcement block 606. A fastening bolt 607 is movably connected between the inner walls of each two fixing holes 612, and a fastening nut 609 is threadedly sleeved on the outer surface of each fastening bolt 607. By passing the fastening bolt 607 through the two tightly fitting fixing holes 612 and then using the fastening nut 609 to tighten the two reinforcement blocks 606, the fixing ring 601 drives the transparent protective cover 501 to be tightly installed on the outside of the water diversion pipe body 1.

[0043] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, multiple connecting rods 605 are fixedly installed on one side of the multiple fixing rings 601, and the multiple connecting rods 605 are evenly divided into multiple groups. One end of each group of connecting rods 605 is fixedly connected to the two sides of the multiple transparent protective covers 501, and one end of the multiple groups of receiving rods 405 are fixedly connected to the other side of the multiple fixing rings 601. The receiving rods 405 can be used to install the detection component 4 and the monitoring component 6 together, and the display component 5 and the monitoring component 6 can be installed together through the connecting rods 605 to achieve simultaneous expansion and closure.

[0044] In the present invention, it is first necessary to install the connecting flanges 2 of multiple adjacent water diversion pipe bodies 1 together. In practice, the connection method of each section of the water diversion pipe body 1 is the same. After being connected together, the water diversion pipe body 1 can be put into use. Among them, the receiving rod 405 is installed on the surface of the water diversion pipe body 1 and can be used to support and fix the metal or concrete structure of the water diversion pipe body 1. A branch pipe 8 is connected to each water diversion pipe body 1. The branch pipe 8 is an auxiliary pipe connected to the main pipe of the water diversion pipe body 1, which can be used to distribute water to different areas or equipment to play a diversion role. When in use, the threaded mounting end of the pointer pressure gauge 9 must first be installed in the fixing sleeve 10. When the water diversion pipe body 1 is produced When a leak occurs, the internal pressure will change. When the staff is checking, they can judge whether there is a leak inside the water diversion pipe body 1 by observing whether the reading of the pointer pressure gauge 9 is stable. When a leak occurs inside the water diversion pipe body 1, the pressure value displayed by the pointer pressure gauge 9 will decrease. By installing the connecting pipe 11 in the corresponding installation sleeve 12, a metal tube rotor flowmeter 7 can be set between each two symmetrical connecting pipes 11. The connecting pipe 11 and the inside of the water diversion pipe body 1 are connected, and the guided water flow will flow through the connecting pipe 11 and the metal tube rotor flowmeter 7. Under normal use, when there is no leakage in the water diversion pipe body 1, the flow rate measured by the metal tube rotor flowmeter 7 will not be significantly different. Changes, when the water diversion pipe body 1 leaks, water will leak out of the leak, and the speed of the water flow through the metal tube rotor flowmeter 7 will change. The inspector can also judge whether there is a leak in the water diversion pipe body 1 of this section by observing the numerical display of the metal tube rotor flowmeter 7. Since the location of the leak is usually the connection of multiple water diversion pipe bodies 1, the color circle 502 is wrapped around the outside of the two connecting flanges 2. The material used for the color circle 502 is a cloth that can be penetrated by liquid. Water indicator is applied to the inner and outer surfaces of the color circle 502. When a leak occurs at the connection between the two connecting flanges 2, the color of the water indicator will change. The extent of the leak can be judged based on the area and speed of the color change of the color circle 502. By taking the two U-shaped fixing rods 608, the fixing ring 601 connected by the two U-shaped fixing rods 608 can be rotated and sleeved on the outer surface of the water diversion pipe body 1. When sleeved, the transparent protective cover 501 is sleeved on the outside of the color-developing circle 502. At this time, each sealing strip 503 is tightly attached to the water diversion pipe body 1, which can make the transparent protective cover 501 in a sealed state, thereby effectively preventing external moisture from entering the transparent protective cover 501 and interfering with the color-developing effect of the color-developing circle 502. By passing the fastening bolts 607 through the two tightly attached fixing holes 612, and then using the fastening nuts 609 to tighten the two reinforcement blocks 606, the fixing ring 601 drives the transparent protective cover 501 to be tightly installed on the outside of the water diversion pipe body 1.The transparent protective cover 501 is connected to the fixing ring 601 through the connecting rod 605 and can rotate with the rotation of the fixing ring 601. The triangular structure of the reinforcing block 603 strengthens the fixing ring 601. When the color ring 502 is wrapped around the outside of the connecting flange 2, the two cameras 613 are activated to monitor the surface of the color ring 502 in all directions. When the color ring 502 appears to be colored, the controller 610 receives an abnormal signal and controls the activation of the alarm. The device 611 sounds an alarm to remind the inspector of the leak, and further inspection and repair of the leak are carried out. The camera 613 can record the color display situation. By starting the multi-stage electric push rod 406, the multi-stage electric push rod 406 is extended and retracted, thereby driving the slide 408 to slide back and forth on the slide rod 403. At this time, the infrared thermal imager 404 is in the turned-on state. The slide 408 will drive the infrared thermal imager 404 to scan the surface of the water diversion pipe body 1. By detecting the temperature abnormality at the leak, the degree of leakage is determined;

[0045] Among them, the infrared thermal imager 404, the metal tube rotor flowmeter 7 and the pointer pressure gauge 9 all belong to the existing technology, and their specific internal structures will not be described in detail. The structure of the infrared thermal imager 404 is composed of: first, the infrared detector, which is the core component of the infrared thermal imager 404 and is used to receive and convert the infrared radiation emitted by the object into an electrical signal; second, the optical system, which includes optical elements such as lenses and reflectors, and is used to collect and focus the infrared radiation emitted by the object and project it onto the infrared detector; third, the signal processing circuit, which is used to amplify, filter, digitize and other processes the infrared radiation signal received by the infrared detector to obtain a visual thermal image; fourth, the display is used to display the processed thermal image. Fifth, a control system is used to control various parameters and functions of the infrared thermal imager 404, which usually includes operation buttons, menus, touch screens, etc. Sixth, a power supply system is used to provide power supply, which is usually a rechargeable battery or directly connected to a power supply. The working principle of the infrared thermal imager 404 is based on the relationship between the infrared radiation emitted by an object and its temperature. When an object is heated, its temperature will affect the intensity and spectral distribution of the infrared radiation it emits. The infrared thermal imager 404 collects the infrared radiation emitted by the object through an optical system and focuses it onto an infrared detector. After receiving the infrared radiation, the infrared detector converts the infrared radiation into an electrical signal according to its working principle. The received infrared radiation signal is amplified, filtered, digitized, etc. by a signal processing circuit. , and then it is converted into the corresponding temperature value through the algorithm, and the pixel points are colored according to the different temperature values ​​to form a thermal image. Finally, the thermal image is displayed to the user through the display. The user can judge the temperature distribution and heat change of the object by observing the thermal image. In addition, the metal tube rotor flowmeter 7 is also called a mechanical flowmeter. Its structural components are: first, the metal tube. The metal tube is the main body of the flowmeter, usually made of stainless steel or other corrosion-resistant materials. It has a certain length and diameter and is used to guide the fluid through and measure the flow rate. Second, the rotor. The rotor is the core component of the metal tube flowmeter, usually made of metal. The rotor rotates in the metal tube and the flow rate of the fluid is calculated by measuring the rotation speed of the rotor. Third, the transmission device. The transmission device will The kinetic energy of the fluid is converted into the rotational kinetic energy of the rotor, which is usually composed of gears or magnetic coupling devices. Fourth, the instrument display part. The flow meter is usually equipped with a pointer or digital display to show the flow rate of the fluid. The working principle of the metal tube rotor flowmeter 7 is based on the interaction between the rotor and the fluid flow. When the fluid passes through the metal tube, the rotor will be impacted by the fluid and rotate. The speed of the rotor is proportional to the flow rate of the fluid. The specific working process is: the fluid enters the metal tube and interacts with the rotor. The rotor is impacted by the fluid and starts to rotate. The transmission device converts the kinetic energy of the fluid into the rotational kinetic energy of the rotor. By measuring the speed of the rotor, the flow rate of the fluid can be calculated. The display part of the flowmeter displays the flow data to the user. Finally,The pointer pressure gauge 9 is an instrument used to measure the pressure of gas or liquid. Its components are as follows: first, the pressure gauge housing, which is usually made of metal and has a certain sealing performance to prevent foreign substances from entering the pressure gauge. Second, the spring. The spring is the core component of the pointer pressure gauge 9 and is usually made of elastic material. Its shape and material selection determine the measuring range and sensitivity of the pressure gauge. Third, the connecting rod and the pointer. The connecting rod is connected to the spring, and the pointer is connected to the connecting rod. When the spring is displaced by pressure, the pointer will also move accordingly. The working principle of the pointer pressure gauge 9 is based on the spring being affected by pressure. When the pressure of the medium being measured acts on the spring of the pressure gauge, the spring undergoes elastic deformation, causing the connecting rod and pointer to move. The magnitude of the displacement is directly proportional to the magnitude of the pressure. The specific working process is as follows: the pressure of the medium being measured acts on the spring of the pressure gauge, and the spring undergoes elastic deformation under the action of pressure. The deformation of the spring causes the connecting rod and pointer to move. The pressure value indicated by the pressure gauge pointer can be read through the scale on the dial. The metal tube rotor flowmeter 7 and the pointer pressure gauge 9 are both installed on the water pipe body 1 and do not need to be connected to a power source when in use.

The model is selected according to the actual use, so the control method and wiring layout of the infrared thermal imager 404, the multi-stage electric push rod 406, the controller 610, the alarm 611 and the camera 613 will no longer be explained in detail.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

2. A detection method for a water diversion pipeline leakage detection device, characterized in that: The device for detecting leakage of a water diversion pipeline according to claim 1 is used, comprising the following steps: S1. Install the connecting flanges (2) of a plurality of adjacent water diversion pipe bodies (1) together. When in use, install the pointer pressure gauge (9) in the fixed sleeve (10). When the water diversion pipe body (1) leaks, its internal pressure will change. When inspecting, the staff can judge whether there is a leak inside the water diversion pipe body (1) by observing whether the reading of the pointer pressure gauge (9) is stable. The guided water flow will flow through the connecting pipe (11) and the metal tube rotor flowmeter (7). Under normal use, when the water diversion pipe body (1) does not leak, the flow rate measured by the metal tube rotor flowmeter (7) will not change significantly. When the water diversion pipe body (1) leaks, water will leak out of the leaking part, and the speed of the water flow through the metal tube rotor flowmeter (7) will change. The inspector can also judge whether there is a leak in the water diversion pipe body (1) by observing the numerical display of the metal tube rotor flowmeter (7). S2. Wrap the color ring (502) around the outside of the two connecting flanges (2). The material of the color ring (502) is a cloth that can be penetrated by liquid. Apply a water indicator on the inner and outer surfaces of the color ring (502). When a leak occurs at the connection between the two connecting flanges (2), the color of the water indicator will change. The extent of the leak can be judged based on the area and speed of the color change of the color ring (502); S3, rotating the fixing ring (601) connected by the two U-shaped fixing rods (608) to cover the outer surface of the water diversion pipe body (1), and the transparent protective cover (501) is covered on the outside of the color development ring (502). At this time, each sealing strip (503) is in close contact with the water diversion pipe body (1), so that the transparent protective cover (501) is in a sealed state, thereby effectively preventing external moisture from entering the transparent protective cover (501) and interfering with the color development of the color development ring (502). By starting the camera (613), the two cameras (613) monitor the surface of the color development ring (502) in all directions. When the color development ring (502) appears to be colored, the controller (610) receives an abnormal signal and controls the alarm (611) to sound an alarm, reminding the inspector of the leak. The camera (613) can record the color development situation; S4. By starting the multi-stage electric push rod (406), the multi-stage electric push rod (406) is extended and retracted, thereby driving the slide plate (408) to slide back and forth on the slide rod (403). At this time, the infrared thermal imager (404) is in the turned-on state, and the slide plate (408) drives the infrared thermal imager (404) to scan the surface of the water diversion pipe body (1) to detect whether there is a leak.
