[0031] Reference Figure 1 and Figure 2In the prior art, the light curing equipment is inserted into the pipeline for curing after spraying by the spraying equipment, the time difference between spraying and curing is long, the sprayed coating is easily contaminated, and after spraying is completed, the trolley with the curing lamp needs to pass through the pipeline again, the trolley is secondly rolled on the coating, which easily causes abrasion of the coating. In the scheme disclosed in the embodiment, the spraying module and the light curing module 2 are both installed on the same mounting rack 1 and move in the pipeline with the mounting rack 1, the spraying module can be quickly cured after spraying, preventing the coating from being contaminated. The construction efficiency is higher, and the cost is lower by integrating the two equipment into one mounting rack 1.
[0032] With reference to Figure 1 and Figure 2 The mounting rack 1 is square-shaped, has a chassis, a front side plate and a rear side plate, and moves in the pipeline while spraying paint towards the front side plate when working. The moving module 4 includes an anti-skid wheel 41 and a walking motor arranged on the chassis, and the walking motor is used to drive the anti-skid wheel 41 to rotate. In some embodiments, the moving module 4 adopts a tracked moving mode, which is different from the above-mentioned embodiments. The mounting rack 1 is provided with supports and interfaces for fixing and installing other functional modules, ensuring the stability and reliability of the modules during movement.
[0033] With reference to Figure 1 and Figure 2A lifting assembly 5 is provided on the rear panel of the mounting bracket 1. The lifting assembly 5 includes a guide rail 51 and a lifting platform 52. The guide rail 51 is vertically mounted on the rear panel, and the lifting platform 52 has a slider on the side near the guide rail 51. The lifting platform 52 is slidably mounted on the rear panel through the engagement of the guide rail 51 and the slider. A dovetail-shaped vertical groove is provided on the side of the slider near the rear panel, and a dovetail-shaped protrusion is provided on the rear panel to prevent the lifting platform 52 from tilting backward. The lifting assembly 5 also includes a locking assembly, which is a locking bolt 54. The locking bolt 54 is threadedly connected to the guide rail 51, and the end of the locking bolt 54 abuts against the slider. The lifting platform 52 can be fixed by rotating the locking bolt 54. The photocuring module 2 and the rotary spraying module 3 are both located on the lifting platform 52. The lifting assembly 5 can control the spraying position and the photocuring illumination position. The photocuring module 2 is used to photocur the sprayed coating. The light curing module 2 includes a lamp tube 21 and a lamp holder 22. The lamp tube 21 is a hollow tube, with one end attached to the lifting platform 52 and the other end extending horizontally away from the lifting platform 52. The lamp holder 22 is located at the end of the lamp tube 21 away from the lifting platform 52, and its power cord passes through the lamp tube 21 and connects to a battery mounted on the mounting bracket 1. In some embodiments, the lamp holder 22 is an integrated COB-LED chip with a power density of 100W / cm², an emission wavelength of 365nm, and a light intensity uniformity ≥95%. The lamp holder 22 dissipates heat through a flexible heat sink with a thickness ≤5mm, which can be bent to fit the inner wall of the lamp tube 21, ensuring effective heat dissipation in complex pipe environments. A lamp cover 23 is also threaded onto the lamp tube 21. The inner wall of the lamp cover 23 has a reflective coating, which reflects the light backward, allowing the light to be concentrated on the coating on the inner wall of the pipe.
[0034] Reference Figure 1 and Figure 2 In order to cool the lamp head 22, a cooling module is also installed inside the lamp tube 21. The cooling module includes a small water tank, a micro water pump and a circulating water pipeline. The water cooling module is powered by a battery. The circulating water pipeline bypasses the lamp head 22 and carries away the heat emitted by the lamp head 22 through the flow of water, thereby controlling the working temperature of the lamp head 22 within a reasonable range and ensuring the stability and service life of the light source.
[0035] Reference Figure 1 and Figure 2 The rotary spraying module 3 includes a liquid storage tank 31, a high-pressure pipeline 32, a nozzle 33, a fixed pipe 341, and a rotating pipe 342, all mounted on the mounting frame 1. The liquid storage tank 31 is mounted on a chassis. The fixed pipe 341 is mounted on a lifting platform 52 and connected to the liquid storage tank 31 via the high-pressure pipeline 32. The rotating pipe 342 is rotatably and sealed to the fixed pipe 341. The nozzle 33 is connected to the rotating pipe 342 and rotates with it. A rotary motor 343 drives the rotating pipe 342 to rotate.
[0036] With reference to Figure 3 and Figure 4 , the fixed pipe 341 and the rotating pipe 342 are both double-layer pipes with an outer pipe and an inner pipe, and have a cavity for accommodating the spraying material between the outer pipe and the inner pipe. The fixed pipe 341 is fixedly arranged on the lifting platform 52, and one end of the fixed pipe 341 is in communication with the cavity in the rotating pipe 342, and the other end is in communication with the liquid storage tank 31 through the high-pressure pipeline 32. The end of the rotating pipe 342 away from the fixed pipe 341 is in communication with the spray head 33. Thus, the material in the liquid storage tank 31 can be delivered to the spray head 33, and the spray head 33 can rotate with the rotating pipe 342. The inner side of the inner pipe is a clearance hole, and the lamp tube 21 passes through the clearance hole and is located at the central axis position of the rotating pipe 342. When the rotating pipe 342 rotates, the rotating pipe 342 drives the spray head 33 to rotate around the lamp tube 21. In this way, the lamp tube 21 can be located on the central axis of the spray head 33 during the rotation and spraying of the spray head 33.
[0037] With reference to Figure 3 and Figure 4 , the fixed pipe 341 includes a first outer pipe 3411 and a first inner pipe 3413 arranged in a nested manner, and the rotating pipe 342 includes a second outer pipe 3421 and a second inner pipe 3423 arranged in a nested manner. The first outer pipe 3411 is in sealing and rotating connection with the second outer pipe 3421. The inner side of the first outer pipe 3411 has a ring-shaped first protrusion 3412, and the inner side of the first protrusion 3412 is in sealing and sliding connection with the outer side of the second outer pipe 3421. The second outer pipe 3421 is provided with a first clamping block 3422, and the first clamping block 3422 is clamped with the first protrusion 3412. A sealing ring 3425 is arranged between the inner side of the first protrusion 3412 and the outer side of the second outer pipe 3421, and a sealing ring 3425 is also arranged between the first clamping block 3422 and the first protrusion 3412.
[0038] With reference to Figure 3 and Figure 4 , the inner side of the first inner pipe 3413 has a ring-shaped second protrusion 3414, and the inner side of the second protrusion 3414 is in sealing and sliding connection with the outer side of the second inner pipe 3423. The second inner pipe 3423 is provided with a second clamping block 3424, and the second clamping block 3424 is clamped with the second protrusion 3414. A sealing ring 3425 is arranged between the inner side of the second protrusion 3414 and the outer side of the second inner pipe 3423, and a sealing ring 3425 is also arranged between the second clamping block 3424 and the second protrusion 3414.
[0039] With reference to Figure 1 and Figure 2 , in actual spraying operation, the spray head 33 moves in the pipeline according to Figure 1The spraying head 33 rotates 360° as shown in the figure, and the inner wall of the pipe is sprayed. The closer the spraying head 33 is to the inner wall of the pipe, the thicker the coating adhered to the unit area. Therefore, in order to ensure the uniform thickness of the coating at each position on the pipe, the rotation axis of the spraying head 33 needs to coincide with the central axis of the pipe, so that the distance between the spraying head 33 and the inner wall of the pipe is the same when the spraying head 33 rotates to each angle. The thicker the coating, the longer the irradiation time needs to be. If the irradiation intensity is high, it may cause the coating to harden insufficiently. Therefore, during the movement of the mounting frame 1, the distance between the lamp head 22 and each position on the pipe wall needs to be the same. Therefore, in the embodiment, the lamp tube 21 is arranged on the central axis of the pipe, and the light can uniformly irradiate the inner wall of the pipe.
[0040] With reference to Figure 1 and Figure 2 , the high-pressure pipeline 32 is provided with a liquid pump 36, which is arranged on the liquid storage tank 31 and used to extract the spraying material in the liquid storage tank 31 and pump it into the fixed pipe 341. The high-pressure pipeline 32 is a hose, so that the lifting of the lifting platform 52 does not affect the liquid conveying of the high-pressure pipeline 32. The high-pressure pipeline 32 is made of a material resistant to high pressure and corrosion. The liquid storage tank 31 stores A and B component materials respectively. The high-pressure pipeline 32 is provided with a two-component plunger pump at one end close to the liquid storage tank 31. The two-component plunger pump is used to convey the A and B component materials. By adjusting the pressure and flow of the pump, the spraying amount can be controlled to meet the construction requirements of different thickness coatings. The spraying head 33 can be adjusted to fan-shaped or conical spraying mode according to the inner diameter of the pipe and the spraying requirements of the coating. In the fan-shaped spraying mode, the coating is diffused in a “flat fan shape”, the spraying surface is a narrow plane, the coverage width is large, and the thickness is relatively uniform. In the conical spraying mode, the coating is diffused in a “conical shape”, the spraying surface is a three-dimensional cone, the coverage range is circular, and the coating concentration in the central area is higher. The spraying angle of the spraying head 33 ranges from 30° to 60°, so as to realize uniform spraying of the inner wall of the pipe. In order to facilitate the conveying of the A and B component materials, the liquid pump 36 is a two-component plunger pump, which can synchronously and accurately convey two kinds of fluids, and control the proportion of the two according to the process requirements, With reference to Figure 1 and Figure 2 , the rotary spraying module 3 further comprises a transmission disc 345, a belt 344 and a rotating motor 343. The transmission disc 345 is arranged around the rotating pipe 342, and the output end of the rotating motor 343 is in transmission connection with the transmission disc 345 through the belt 344. When the output end of the rotating motor 343 rotates, the transmission disc 345 is driven to rotate through the belt 344, and then the rotating pipe 342 is driven to rotate.
[0041] With reference to Figure 1 and Figure 2The spray head 33 is communicated with the rotating pipe 342 through a spray pipe 35, the spray pipe 35 includes a horizontal section 351 and a vertical section 352, one end of the horizontal section 351 is communicated with the rotating pipe 342, the horizontal section 351 is arranged parallel to the lamp pipe 21, the vertical section 352 is communicated with the horizontal section 351 and the spray head 33, and the vertical section 352 is perpendicular to the lamp pipe 21. The horizontal section 351 is supported by a bearing 37 between the horizontal section 351 and the lamp pipe 21, and the bearing 37 can enhance the stability when the horizontal section 351 rotates. The horizontal section 351 and the vertical section 352 are detachably connected through threads, the vertical section 352 can be retracted when not working, the height of the whole device is reduced, and the whole device is more conducive to storage and transportation.
[0042] With reference to Figure 1 and Figure 2 , the mounting rack 1 is further provided with a cooperative control unit for regulating the pressure of the spray head 33, the light intensity of the lamp head 22 and the rotating speed of the rotating pipe 342. The cooperative control unit includes a PLC controller, a sensor group and a data processing module. The sensor group includes an infrared thickness gauge, an ultraviolet light intensity sensor, a temperature sensor and a pressure sensor. The infrared thickness gauge is used for real-time monitoring of the coating thickness; the ultraviolet light intensity sensor is used for real-time detection of the ultraviolet light irradiation intensity; the temperature sensor is used for monitoring the coating surface and the LED light source temperature; and the pressure sensor is used for monitoring the pressure of the spraying system. The PLC controller receives the data collected by each sensor, analyzes and processes the data through the built-in algorithm model, automatically adjusts the pressure and flow of the spraying system and the light source moving speed and light intensity of the ultraviolet light curing unit according to the set coating thickness, curing requirements and other parameters, and realizes dynamic cooperative control of the spraying and curing processes. When the infrared thickness gauge detects that the coating thickness increases by 0.5 mm, the PLC controller automatically reduces the flow of the spraying system and synchronously reduces the light source moving speed of the ultraviolet light curing unit, so that the coating can be fully cured.
[0043] With reference to Figure 1 and Figure 2 , the mounting rack 1 is further provided with an image acquisition system, the image acquisition system includes a high-definition camera, the high-definition camera is arranged on the front side plate of the mounting rack 1 and has a 360° rotation and zoom function, can acquire image information inside the pipeline in real time and transmit the image information to the ground control terminal, and the operator can master the internal condition of the pipeline and the equipment operation condition in real time. The mounting rack 1 is further provided with a communication module, the communication module adopts a combination of wireless communication and wired communication, for example, Bluetooth, WiFi and cable. The communication module is used for data transmission and instruction interaction between the equipment and the ground control terminal. The wireless communication is suitable for short-distance operation scenes and is convenient to operate; the wired communication is suitable for long-distance pipeline operation and is stable and reliable in signal, so that the effective control of the equipment in a complex environment is ensured.
[0044] With reference to Figure 1 and Figure 2, preset the coating thickness (such as 1.5mm) before spraying, the PLC controller can automatically calculate the spraying flow and the moving speed of the ultraviolet lamp; during the spraying process, the infrared thickness gauge feedbacks the coating thickness in real time, and when the thickness deviates, the spraying pressure is automatically adjusted, and at the same time, the device synchronously adjusts the moving speed, for example, when the thickness increases by 0.5mm, the speed is reduced to 0.8m / min.
[0045] With reference to Figure 1 and Figure 2 In some embodiments, for the repair of municipal large-diameter pipes (pipe nominal diameter between 500mm and 1500mm), a vehicle-mounted chassis integrated two-component airless spraying pump with a pressure of 15MPa and a flow of 15L / min is used, an LED ultraviolet light power supply with a total power of 6000W is used, the speed of the device is 0.8m / min, the distance between the lamp head 22 and the spray head 33 is 0.5m, and the light intensity is 800mW / cm² to cure the coating. For the repair of small-diameter pipes (pipe nominal diameter between 100mm and 300mm): the spray head 33 uses air-assisted atomization with a pressure of 0.5MPa, the thickness of the coating is 0.3-0.8mm; the ultraviolet lamp group is a ring array, which is matched with a flexible light guide strip to ensure uniform light intensity at the bend. Compared with the traditional process, the processing time is saved, and the cost is saved.
[0046] The implementation process of the embodiment of the present application is: Detection and preparation: use the detection robot to detect the drainage pipe, obtain the internal defect information of the pipe, including the position and degree of cracks, corrosion, leakage points, etc., and generate a detailed detection report. According to the detection results, use high-pressure water jet equipment (pressure 100-280MPa) or mechanical scraper equipment to clean the inner wall of the pipe, remove silt, scale and other impurities, and ensure that the inner wall of the pipe is clean and dry. For severely deformed or damaged parts, first perform local repair, such as using grouting filling to restore the structural integrity of the pipe.
[0047] Equipment installation and debugging: adjust the height of the lifting platform 52 so that the rotating shaft of the rotating pipe 342 is located at the center axis position of the pipe, when the rotating pipe 342 rotates, the spray head 33 uniformly sprays the inner wall of the pipe, and the lamp head 22 is located at the center axis of the pipe and uniformly irradiates the inner wall of the pipe.
[0048] Spraying and curing: The installed and debugged equipment is put into the sewer through the inspection well, and moves to the deep part of the pipeline under the action of the walking motor according to the preset path. When the equipment reaches the repair starting position, the spraying system is started, and the two-component piston pump delivers the A and B components to the spray head 33 in proportion, and sprays at a set pressure and flow rate through the high-pressure pipeline 32 to form a continuous and uniform coating on the inner wall of the pipeline. During the spraying process, the infrared thickness gauge monitors the coating thickness in real time and transmits the data to the PLC controller. The PLC controller automatically adjusts the pressure and flow rate of the spraying system according to the difference between the preset coating thickness and the actual detected thickness, to ensure that the coating thickness meets the requirements. The LED light source of the lamp head 22 in the light curing module 2 irradiates and cures the just sprayed coating at a set light intensity and moving speed. The ultraviolet light intensity sensor detects the light intensity in real time and feeds back to the PLC controller. If the light intensity fluctuates, the PLC controller automatically adjusts the light intensity adjusting mechanism to ensure the stability of the light intensity. During the whole spraying and curing process, the temperature sensor monitors the coating surface and LED light source temperature in real time, and when the temperature exceeds the set threshold, the PLC controller automatically adjusts the spraying speed, light source moving speed or starts the cooling system to ensure the safety of the operation and the curing effect.
[0049] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
