Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, and more specifically, to a temperature monitoring instrument based on cipp pipeline repair. Background Technology

[0002] CIPP (Chip-In-Place) pipeline repair is a trenchless underground pipeline repair technology that originated in the UK in the 1970s. To date, it is the most widely used trenchless underground pipeline repair technology in the world. CIPP technology has a wide range of applications and is suitable for trenchless repair of pressure pipelines such as gravity flow pipelines, water supply, and gas pipelines.

[0003] Currently, CIPP involves inserting a resin-impregnated tubing into the damaged pipe, then using an air compressor to inflate the tubing, causing it to rotate and advance along the damaged pipe to adhere the resin to it. Finally, heating is used to cure the resin, thus fixing the tubing inside the damaged pipe for repair. However, when using CIPP technology to repair pipes, it is difficult to control the temperature of the curing tubing, which can easily lead to uneven heating of the resin on the tubing and affect the pipe repair effect. Therefore, this utility model proposes a temperature monitoring instrument based on CIPP pipe repair. Utility Model Content

[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a temperature monitoring instrument based on cipp pipe repair, which aims to solve the problem that in the prior art, when using cipp technology to repair pipes, the temperature of the heating and curing of the inner lining hose is not easy to control, which easily leads to uneven heating of the resin on the inner lining hose and affects the pipe repair effect.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution: A temperature monitoring device based on CIPP pipe repair includes a base box and a cover. The cover is hinged to the base box via a hinge shaft. A V-CIPP thermostat is fixedly connected inside the base box, and a display is fixedly connected inside the cover. The display is electrically connected to the V-CIPP thermostat. A sensing optical fiber is detachably connected to the V-CIPP thermostat, with one end of the sensing optical fiber located outside the base box. A screw is rotatably connected to one side of the base box, and a threaded block is threaded onto the circumferential surface of the screw. Two pressure rods are rotatably connected to one side of the base box, and the two pressure rods correspond to the sensing optical fiber. The two pressure rods are respectively hinged to the symmetrical ends of the threaded blocks via hinge shafts.

[0006] As a preferred embodiment of this utility model, the V-CIPP temperature controller is equipped with a laser, a beam splitter, a reflector, and a signal processor. The laser emits laser pulses that penetrate the beam splitter, enter the sensing optical fiber, and generate backscattered light. The backscattered light penetrates the reflector, is collected and processed by the signal processor, and is displayed on the display.

[0007] As a preferred embodiment of this utility model, the top of the base box is provided with a lead wire port, and the sensing optical fiber moves through the lead wire port.

[0008] As a preferred embodiment of this utility model, a positioning block is fixedly connected to one side of the base box, and the sensing optical fiber is matched with the positioning block.

[0009] As a preferred embodiment of this utility model, rubber pads are fixedly connected to both pressure rods, and the two rubber pads correspond to the sensing optical fiber.

[0010] As a preferred embodiment of this utility model, a guide rod assembly is fixedly connected to one side of the bottom box, and a threaded block is slidably connected to the inner side of the guide rod assembly.

[0011] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: In this solution, when using CIPP technology for pipe repair, the inner lining pipe needs to be heated to cure the resin between the inner lining pipe and the damaged pipe, thus completing the repair. While heating the resin on the inner lining pipe, one end of the sensing fiber is connected to the V-CIPP temperature controller. Two pressure rods fix the portion of the sensing fiber located outside the base box, ensuring a stable connection between the sensing fiber and the V-CIPP temperature controller and preventing poor contact due to pulling. The other end of the sensing fiber is inserted into the damaged pipe and evenly distributed according to the length of the inner lining pipe to sense the local temperature within the pipe, collecting temperature data from different areas. The V-CIPP temperature controller displays the temperature data collected by the sensing fiber on a monitor, allowing construction personnel to better control the curing quality of the resin on the inner lining pipe and ensure the pipe repair effect.

[0012] In this solution, in the scenario of monitoring the curing temperature of hose materials for trenchless pipeline repair, the entity executing the data acquisition and data usage steps of the hose material curing temperature includes, but is not limited to, a mobile terminal that is independent of the on-site temperature monitoring equipment. That is, through this mobile terminal, the data acquisition of the hose curing temperature and subsequent data usage operations (such as temperature curve generation and curing quality prediction) can be completed without the local operation of the on-site temperature monitoring equipment, so as to adapt to the scenario requirements of trenchless pipeline repair operations where on-site space is limited and remote and flexible monitoring is required.

[0018] Example:

[0019] Please see Figure 1-4 A temperature monitoring device based on CIPP pipe repair includes a base box 1 and a cover 2. The cover 2 is movably hinged to the base box 1 via a hinge shaft. A V-CIPP thermostat 3 is fixedly connected inside the base box 1. A display 4 is fixedly connected inside the cover 2, and the display 4 is electrically connected to the V-CIPP thermostat 3. A sensing fiber 5 is detachably connected to the V-CIPP thermostat 3, and one end of the sensing fiber 5 is located outside the base box 1. A screw 6 is rotatably connected to one side of the base box 1. A threaded block 7 is threadedly connected to the circumferential surface of the screw 6. Two pressure rods 8 are rotatably connected to one side of the base box 1, and the two pressure rods 8 correspond to the sensing fiber 5. The two pressure rods 8 are respectively movably hinged to the symmetrical ends of the threaded block 7 via hinge shafts via connecting rods 9.

[0020] In this embodiment, when repairing the pipe using the CIPP method, one end of the sensing fiber 5 is connected to the V-CIPP thermostat 3, and the other end is on the outside of the base box 1. By passing the portion of the sensing fiber 5 on the outside of the base box 1 through two pressure rods 8, the screw 6 is rotated to move the threaded block 7 closer to the base box 1. The threaded block 7 pushes the two pressure rods 8 to rotate through two connecting rods 9, causing the two pressure rods 8 to rotate and unfold to press down on the sensing fiber 5, thereby fixing the portion of the sensing fiber 5 on the outside of the base box 1 to one side of the base box 1. This prevents the connection between the sensing fiber 5 and the V-CIPP thermostat 3 from being pulled and causing poor contact. Then, one end of the sensing fiber 5 is evenly distributed inside the pipe. The resin between the hose and the damaged pipe is heated by water or gas heating. During the heating process, the V-CIPP thermostat 3 collects temperature data from different areas inside the pipe through the sensing fiber 5. Finally, the temperature data is displayed on the display 4 inside the box cover 2, which facilitates the staff to confirm and adjust the heating temperature and ensure the heating effect.

[0021] Specifically, the V-CIPP temperature controller 3 is equipped with a laser 31, a beam splitter 32, a reflector 33, and a signal processor 34. The laser 31 emits laser pulses that penetrate the beam splitter 32 and enter the sensing fiber 5, generating backscattered light. The backscattered light penetrates the reflector 33, is collected and processed by the signal processor 34, and is displayed on the display 4.

[0022] In this embodiment, the temperature measurement of the V-CIPP temperature controller 3 is based on the spontaneous Raman scattering effect. After a high-power narrow-pulse laser pulse LD penetrates the beam splitter 32 and is incident on the sensing fiber 5, the laser interacts with the fiber molecules to generate extremely weak backscattered light. The scattered light has three wavelengths: Rayleigh, anti-stokes, and stokes light. Among them, anti-stokes light is temperature sensitive to all environments of the fiber and serves as the signal light; stokes light is not temperature sensitive and serves as the reference light. The signal light backscattered from the sensing fiber passes through the beam splitter filter again to isolate the Rayleigh scattered light and pass through the temperature-sensitive anti-stokes signal light and the temperature-insensitive stokes reference light. The signal light is received by the signal processor 34, and the temperature can be calculated based on the ratio of the light intensities of the two. The location is determined based on optical time-domain reflectometry (OTDR) technology. The fiber position corresponding to the scattered signal can be determined by measuring the echo time of the scattered signal using high-speed data acquisition.

[0023] Specifically, the top of the bottom box 1 is provided with a lead wire port 10, and the sensing optical fiber 5 moves through the lead wire port 10.

[0024] In this embodiment, the lead-in port 10 is used to locate the position of the sensing fiber 5, so that the sensing fiber 5 can enter the pipe from the outside of the bottom box 1.

[0025] Specifically, a positioning block 11 is fixedly connected to one side of the bottom box 1, and the sensing fiber 5 is matched with the positioning block 11.

[0026] In this embodiment, the positioning block 11 is used to position the sensing optical fiber 5 so that the sensing optical fiber 5 can be accurately pressed and fixed in accordance with the two pressure rods 8.

[0027] Specifically, rubber pads 12 are fixedly connected to both pressure rods 8, and the two rubber pads 12 correspond to the sensing optical fiber 5.

[0028] In this embodiment, when the two pressure rods 8 are pressing and fixing the sensing optical fiber 5, the two rubber pads 12 will come into contact with the sensing optical fiber 5. The two rubber pads 12 have a certain elasticity and friction, which improves the pressing effect of the two pressure rods 8 on the sensing optical fiber 5 while avoiding damage.

[0029] Specifically, a guide rod assembly 13 is fixedly connected to one side of the bottom box 1, and a threaded block 7 is slidably connected to the inside of the guide rod assembly 13.

[0030] In this embodiment, when the threaded block 7 moves, the guide rod assembly 13 restricts the linear movement of the threaded block 7, making the movement of the threaded block 7 more stable.

[0031] Working principle: One end of the sensing fiber optic cable 5 is placed inside the base box 1 and connected to the V-CIPP temperature controller 3. The other end of the sensing fiber optic cable 5 is located on the outside of the base box 1. The part of the sensing fiber optic cable 5 located on the outside of the base box 1 is placed inside the two pressure rods 8. By rotating the screw 6, the threaded block 7 moves closer to the base box 1. The threaded block 7 pushes the two pressure rods 8 through the two connecting rods 9. The two pressure rods 8 rotate and press the sensing fiber optic cable 5 on one side of the base box 1, fixing the sensing fiber optic cable 5 on one side of the base box 1 and preventing poor contact caused by pulling at the connection between the sensing fiber optic cable 5 and the V-CIPP temperature controller 3. Then, the end of the sensing fiber optic cable 5 located on the outside of the base box 1 is placed into the pipe and evenly distributed to monitor the temperature of the pipe being repaired by the CIPP method. The sensing fiber optic cable 5 senses the temperature of different areas in the pipe and transmits the local temperature data to the V-CIPP temperature controller 3. The V-CIPP temperature controller 3 displays the data on the display 4 inside the box cover 2, which is convenient for the staff to confirm and adjust the heating temperature.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
