Technical Field

[0001] This utility model relates to the field of tunnel wall protection technology, and in particular to a spraying system for long-distance water conveyance tunnels. Background Technology

[0002] Long-distance water conveyance tunnels are key structures in water conservancy and water diversion projects. To ensure the long-term safe operation of the tunnels and prevent weathering, leakage, and erosion of the concrete or rock mass by water flow, a special coating with anti-corrosion, anti-seepage, and reinforcement functions is usually applied to the tunnel wall surface. However, conducting efficient, uniform, and high-quality spraying operations in long-distance, large-diameter tunnels with complex environments presents numerous technical challenges:

[0003] 1. The thickness and uniformity of the coating are highly dependent on the worker's experience and skill level, which can easily lead to problems such as uneven thickness and missed areas.

[0004] 2. Traditional methods require frequent interruptions for manual resupply, which severely restricts continuous operation capabilities and significantly reduces construction efficiency.

[0005] 3. The tunnel cross-section may be irregular, and changes in the distance between the spraying equipment and the tunnel wall will affect the spraying effect.

[0006] Therefore, there is an urgent need for a highly automated, integrated spraying system capable of long-distance continuous operation to solve the above problems and improve the efficiency, quality, and safety of spraying construction on the inner walls of long-distance water conveyance tunnels.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0034] The following describes some embodiments of the collision detection device of the present invention with reference to the accompanying drawings.

[0035] like Figures 1 to 3 As shown, this embodiment discloses a spraying system for long-distance water conveyance tunnels, including an electronic control device and a spraying device 20 and a supply device 30 electrically connected to the electronic control device. The electronic control device is used to control the operation of the spraying device 20 and the supply device 30 according to a preset program.

[0036] The spraying device 20 includes a first traveling component 21, a spraying component 22 and a measuring component 23 disposed on the first traveling component 21. The measuring component 23 is used to detect the distance between the spraying component 22 and the cavity wall and the thickness of the paint sprayed on the cavity wall. The spraying component 22 sprays paint onto the cavity wall according to the detection results of the measuring component 23.

[0037] The supply device 30 includes a second walking assembly 31 and a power supply assembly 32 and a paint supply assembly 33 disposed on the second walking assembly 31. The power supply assembly 32 is used to supply power to the paint supply assembly 33, the spraying assembly 22 and the measuring assembly 23. The paint supply assembly 33 is used to supply paint to the spraying assembly 22.

[0038] The first walking component 21 is used to walk along a set route in the tunnel, and the second walking component 31 moves synchronously with the first walking component 21.

[0039] This application discloses a spraying system for long-distance water conveyance tunnels. A spraying component 22 and a measuring component 23 are mounted on a first traveling component 21, while a power supply component 32 and a paint supply component 33 are mounted on a second traveling component 31. The spraying system employs a separate but synchronously moving spraying device 20 and a supply device 30. The supply device 30 continuously provides power and paint to the spraying device 20. The power supply component 32 acts as a mobile power source, directly following the spraying device 20. This effectively solves the problems of insufficient fixed power supply points or difficulties in cable dragging in long tunnels, providing a stable and reliable power supply. The component 33 moves synchronously with the supply device 30, and can carry a large amount of paint, enabling continuous and convenient paint delivery and supporting long-term continuous operation. This solves the problem of frequent shutdowns caused by supply interruptions in traditional spraying processes, achieving uninterrupted continuous spraying operations in ultra-long tunnels and greatly improving construction efficiency. The measuring component 23 detects in real time the distance between the spraying component 22 and the tunnel wall, as well as the thickness of the paint sprayed on the tunnel wall. The spraying component 22 dynamically adjusts the spraying parameters based on real-time data, achieving closed-loop control and ensuring uniform and accurate protective paint thickness, effectively avoiding problems such as missed spraying or insufficient thickness. Based on the cooperation of the electrical control device, the spraying device 20, and the supply device 30, this application effectively overcomes many bottlenecks in long-distance water conveyance tunnel spraying operations, achieving safe, efficient, high-quality, and continuous spraying construction.

[0040] The supply device 30 can continuously supply paint and power to the spraying device 20. The supply device 30 may include a second walking component 31, a paint supply component 33, and a power supply component 32. The paint supply component 33 can continuously produce protective paint based on raw materials and deliver it to the spraying device 20. For example, the protective paint can be produced by mixing one or more raw materials. The paint supply component 33 consists of at least a stirrer and a screw conveyor. The stirrer mixes the raw materials, and the screw conveyor and corresponding pipelines deliver the protective paint to the spraying device 20.

[0041] The power supply component 32 can output different levels of AC or DC power to supply power to equipment such as the spraying device 20 and paint supply component 33 in the spraying system. The power supply component 32 can be one or a combination of a generator module or a battery module 321. For example, the power supply component 32 can use a battery module 321 to supply power externally. Increasing the battery capacity in the battery module 321 can improve the operating time of the electrical equipment in the spraying system. It should be noted that in some embodiments, the power supply component 32 can use a combination of a battery module and a generator module to supply power to the electrical equipment in the spraying system.

[0042] The second traveling assembly 31 can be used to carry equipment such as the power supply assembly 32 and the paint supply assembly 33, and the second traveling assembly 31 can move along with the spraying device 20 through intelligent driving and / or manned driving. Specifically, when the spraying device 20 performs a spraying task in the tunnel, when the spraying device 20 moves in the long water conveyance tunnel, the second traveling assembly 31 can be kept at a certain distance from the first traveling assembly 21 through manned driving. This not only ensures that the paint supply assembly 33 can reliably output protective paint to the spraying device 20, but also ensures that the power supply assembly 32 continuously supplies power to the spraying device 20.

[0043] The spraying device 20 may include a first traveling component 21, a spraying component 22, and a measuring component 23. The first traveling component 21 may carry the spraying component 22 and the measuring component 23, and the first traveling component 21 can travel in the tunnel along a pre-set path. The spraying component 22 can spray protective paint supplied from the paint supply component 33 onto the tunnel wall. The measuring component 23 can at least be used to detect the distance between the spraying component 22 and the tunnel wall and to detect the thickness of the protective paint sprayed on the tunnel wall. For example, before the spraying component 22 needs to spray, the measuring component 23 first detects the distance between the spraying component 22 and the tunnel wall to ensure that the distance between the spraying component 22 and the tunnel wall is maintained within the set distance before spraying begins. Then, the measuring component 23 detects the thickness of the protective paint on the tunnel wall. If it meets the standard, the next work area is sprayed; if it does not meet the standard, the spraying task for that area is repeated.

[0044] It should be noted that the measuring component 23 includes a sensor for detecting the distance between the spraying component 22 and the cavity wall, and a sensor for detecting the thickness of the protective coating.

[0045] The electronic control device can be installed on the first walking assembly 21 and / or the second walking assembly 31. For example, the electronic control device includes a first electronic control module and a second electronic control module. The first electronic control module is installed on the first walking assembly 21 and electrically connected to the spraying assembly 22 and the measuring assembly 23. The second electronic control module is installed on the second walking assembly 31 and electrically connected to the paint supply assembly 33. The second electronic control module is electrically connected to the first electronic control module.

[0046] like Figures 2 to 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the spraying assembly 22 includes a spray gun module 221, a rotary telescopic mechanism 222, and a pressurized conveying module 223. The spray gun module 221 is connected to the paint supply assembly 33 through the pressurized conveying module 223. The pressurized conveying module 223 is used to pressurize the received low-pressure paint to obtain high-pressure paint and convey it to the spray gun module 221. The rotary telescopic mechanism 222 is connected to the spray gun module 221 and is used to drive the spray gun module 221 to rotate and / or extend relative to the cavity wall.

[0047] The spray gun module 221 can rotate and extend relative to the tunnel via the rotary telescopic mechanism 222. When the rotary telescopic mechanism 222 extends or retracts, the spray gun module 221 can automatically extend or retract according to the distance between the spray gun module 221 and the tunnel wall fed back in real time by the measuring component 23 to maintain the optimal spraying distance. When the rotary telescopic mechanism 222 rotates, the spray gun module 221 can adapt to the complex tunnel contour and complete the spraying of the entire circumference of the tunnel.

[0048] For example, the rotary telescopic mechanism 222 may include a rotary component 2221 and a telescopic component 2222. The rotary component 2221 includes a first gear shaft 22211, a second gear shaft 22212, a first drive module 22213, and a second drive module 22214. The first gear shaft 22211 and the second gear shaft 22212 are coaxially arranged and rotatably connected. The first gear shaft 22211 is driven by the spraying component 22 and the first drive module 22213, respectively. The second gear shaft 22212 is driven by the measuring component 23 and the second drive module 22214, respectively. The first drive module 22213 drives the first gear shaft 22211 to rotate. The first drive module 22213 includes a first drive motor, the output end of which is meshed with the teeth of the first gear shaft 22211. The second drive module 22214 drives the second gear shaft 22212 to rotate. The second drive module 22214 includes a second drive motor, the output end of which is meshed with the teeth of the second gear shaft 22212. The second gear shaft 22212 has a groove structure with openings at both ends inside. The diameter of the groove structure is larger than the shaft diameter of the first gear, so that the second gear shaft 22212 can be fitted onto the first gear shaft 22211, and the first gear shaft 22211 and the second gear shaft 22212 are coaxially arranged.

[0049] The telescopic assembly 2222 can consist of a motor, a lead screw, a multi-stage telescopic arm, and a guide rail. There can be two telescopic assemblies 2222, which are respectively connected to the spraying assembly 22 and the measuring assembly 23. The telescopic assembly 2222 can adjust the distance between the spraying assembly 22 or the measuring assembly 23 and the hole wall.

[0050] The pressurized conveying module 223 can pressurize the low-pressure paint supplied by the paint supply component 33, converting it into the high-pressure paint required for spraying, and then deliver the high-pressure paint to the spray gun module 221 to ensure the atomization effect of the paint. Specifically, the pressurized conveying module 223 includes a storage tank 2231, a hydraulic pump 2232, a high-pressure pump 2233, a reciprocating cylinder 2234, and an oil tank 2235. The storage tank 2231 is connected to the inlet of the high-pressure pump 2233, and the outlet of the high-pressure pump 2233 is connected to the spray gun module 221 through a diverter valve. The outlet of the oil tank 2235 is connected to the reciprocating cylinder 2234 through the hydraulic pump 2232, and the reciprocating cylinder 2234 is also connected to the return port of the oil tank 2235. When the hydraulic pump 2232 is activated, it draws oil from the oil tank 2235 and pressurizes it. Pressurized oil enters the reciprocating cylinder 2234, driving its reciprocating motion mechanism to perform reciprocating motion; the motion of the reciprocating motion mechanism in the reciprocating cylinder 2234 directly drives the piston / plunger of the high-pressure pump 2233 to perform synchronous reciprocating motion; the suction stroke of the piston / plunger of the high-pressure pump 2233 draws the paint from the storage tank 2231 into the pump chamber; the discharge stroke of the piston / plunger of the high-pressure pump 2233 pressurizes the drawn paint into high pressure and discharges it from the outlet of the spray gun module 221; the low-pressure hydraulic oil discharged after the reciprocating cylinder 2234 completes its action flows back to the oil tank 2235.

[0051] like Figures 2 to 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the spraying component 22 also includes a lifting module 224, the lifting module 224 is disposed on the first walking component 21, and the lifting module 224 is connected to the rotary telescopic mechanism 222. The lifting module 224 is used to drive the rotary telescopic mechanism 222 to move up and down along the height direction of the tunnel.

[0052] The lifting module 224 drives the rotary telescopic mechanism 222 to move up and down along the height of the tunnel. Specifically, the lifting module 224 includes a third drive module 2241, a lifting bracket 2242, and an assembly bracket 2243. The rotary telescopic mechanism 222 is mounted on the lifting bracket 2242, and the third drive module 2241 is mounted on the assembly bracket 2243. The assembly bracket 2243 is fixed to the first traveling component 21. The lifting bracket 2242 is provided with sliding teeth that mesh with the output end of the third drive module 2241. A sliding guide rail is provided between the lifting bracket 2242 and the assembly bracket 2243. When the third drive module 2241 rotates, the lifting bracket 2242 moves up and down relative to the assembly bracket 2243, thereby driving the rotary telescopic mechanism 222 to move up and down along the height of the tunnel. In addition, by providing a sliding guide rail between the lifting bracket 2242 and the assembly bracket 2243, the lifting bracket 2242 can move more smoothly and reliably during the lifting process.

[0053] like Figures 2 to 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first walking component 21 is an AGV trolley.

[0054] The first walking component 21 can autonomously walk and operate in long-distance water conveyance tunnels under the control of preset programs or real-time commands. The AGV can achieve high-precision positioning and stable tracking in tunnel environments without GPS signals based on technologies such as laser, inertial navigation, or magnetic strip / QR code navigation. It can also accurately control its walking speed and precisely match it with spraying parameters such as paint flow rate to ensure a constant amount of paint sprayed per unit area and uniform spraying thickness.

[0055] In addition to the features of the above embodiments, this embodiment further specifies that: the second walking assembly 31 is a two-way driving vehicle, and an assembly platform 301 for mounting the power supply assembly 32 and the paint supply assembly 33 is formed on the second walking assembly 31.

[0056] The second traveling assembly 31 can be a two-way driving vehicle, with complete driving control systems at both ends. The driver can quickly switch between forward and reverse driving modes simply by switching the driving end, eliminating the need for the second traveling assembly 31 to turn around in narrow tunnels. Furthermore, the second traveling assembly 31 is equipped with an assembly platform 301, which provides a stable, reliable, and large-load-bearing mounting base for larger power supply components 32 (such as diesel generator sets, large battery packs) and paint supply components 33 (such as large-capacity storage tanks and conveying pump stations), thereby providing a stable supply to the painting device 20.

[0057] The two-way driving vehicle can be a gasoline or battery-powered vehicle. The second walking component 31 does not need to be towed by other means of transport and can drive itself from the base to the supply center outside the tunnel and then back to the work point. It should be noted that the number of supply devices 30 in the spraying system can be no less than two. The use of no less than two supply devices 30 to switch back and forth reduces the downtime of the spraying device 20 and improves the working efficiency of the spraying system.

[0058] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the power supply component 32 includes a battery module 321 and a power inverter 322, the number of battery modules 321 is multiple, and the power inverter 322 is connected to multiple battery modules 321 to output AC power to the first walking component 21, the spraying component 22 and the measuring component 23.

[0059] The power supply component 32 relies entirely on battery power, completely avoiding the emissions problems caused by using diesel generators in enclosed, poorly ventilated tunnels. This ensures personnel health and safety, meets increasingly stringent environmental protection construction requirements, and is particularly suitable for long-distance, deeply buried tunnels. The power supply component 32 may include battery modules 321 and power inverters 322. The number of battery modules 321 can be multiple, and the number can be flexibly increased or decreased according to the size of the assembly platform 301 in the second travel component 31 and actual operational needs such as spraying time, equipment power, and tunnel length.

[0060] The power inverter 322 can efficiently and stably convert the DC power output from multiple battery modules 321 into the AC power required by the equipment, such as 220V / 380V.

[0061] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the paint supply component 33 includes a stirring and grinding module 331 and a paint conveying module 332, the assembly platform 301 is divided into a raw material storage area 302, the stirring and grinding module 331 is used to grind and stir one or more raw materials to obtain paint, the paint conveying module 332 is connected to the stirring and grinding module 331 to convey the paint to the spraying component 22, and the raw material storage area 302 is used to store one or more raw materials for making paint.

[0062] The mixing and grinding module 331 and the paint conveying module 332 are both installed on the second traveling component 31. The entire flow of "raw material - grinding and mixing - finished paint - conveying and spraying" can be realized on the second traveling component 31. Based on the synchronous movement of the second traveling component 31 and the first traveling component 21, the distance between the two traveling components is kept within a certain range, avoiding the problem of paint solidification during pipeline transportation caused by excessively long pipeline distance between the paint conveying module 332 and the spraying component 22. Moreover, the mixing and grinding module 331 can continuously produce paint, which, together with the paint conveying module 332, can stably supply the spraying end, avoid spraying interruption, and reduce dependence on pre-mixed paint supply outside the tunnel. This is especially advantageous at the operation point of long water conveyance tunnels.

[0063] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a flexible connection structure 40 is provided between the first walking component 21 and the second walking component 31, the two ends of the flexible connection structure 40 are respectively connected to the first walking component 21 and the second walking component 31, and the flexible connection structure 40 can perform telescopic movement to limit the distance between the first walking component 21 and the second walking component 31.

[0064] The flexible connection structure 40 can dynamically limit the distance between the first walking component 21 and the second walking component 31. The flexible connection structure 40 can be a spring damping system, a hydraulic buffer, or an elastic tow cable, etc. The flexible structure can be designed with a maximum / minimum extension length of 3-5 meters, forcing the distance between the first walking component 21 and the second walking component 31 to be kept within a safe range. This not only prevents the second walking component 31 from accidentally accelerating and colliding with the first walking component 21, but also prevents the first walking component 21 from suddenly accelerating and tearing off the pipeline between the spraying device 20 and the supply device 30.

[0065] It should be noted that the flexible connection structure 40 can integrate cable / pipe channels, which can bind the power supply lines, paint pipes, signal lines, etc. between the spraying device 20, the supply device 30 and the electrical control device to the connection structure. This can prevent the pipelines from extending and retracting synchronously with the flexible connection structure 40, eliminating the risk of twisting and knotting.

[0066] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the flexible connection structure 40 includes a connecting rod 41, a support rod 42 and a caster wheel 43, the number of connecting rods 41 is multiple, two adjacent connecting rods 41 are hinged, and at least one of two adjacent connecting rods 41 is connected to the caster wheel 43 through the support rod 42.

[0067] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further includes a video monitoring device, which is installed on the first walking component 21 and / or the second walking component 31, and transmits video content to the command center via wired or wireless means.

[0068] In addition to the features of the above embodiments, this embodiment further includes a lighting device that is electrically connected to the power supply component 32 and is disposed on the first walking component 21 and / or the second walking component 31.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
