Description

Technical Field

[0001] The present invention relates to the technical field of tunnel cleaning, in particular to an intelligent flushing device for an intercity railway tunnel. Background Art

[0002] Tunnels, as critical structural components in intercity railway construction and maintenance, are crucial for safe train operation and passenger comfort. Due to long-term exposure to the external environment and various factors generated by train operation, tunnel walls often accumulate foreign matter such as dust, oil, and dirt. These deposits not only detract from the tunnel's aesthetics but, more importantly, pose a potential threat to train safety and the durability of the tunnel structure.

[0003] Traditional tunnel cleaning methods rely on manually operated high-pressure water cannons or mechanical cleaning equipment. These methods are not only inefficient but also difficult to ensure uniform and thorough cleaning. Furthermore, manual inspection of tunnel wall cleanliness is a time-consuming and tedious process, often requiring multiple flushing and inspections to ensure both sides of the tunnel meet cleanliness standards. This undoubtedly increases maintenance costs and construction time. Summary of the Invention

[0004] The present invention provides an intelligent flushing device for an intercity railway tunnel, so as to solve the problem of low efficiency of manual cleaning.

[0005] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0006] An intelligent flushing device for an intercity railway tunnel comprises a washing vehicle, wherein the washing vehicle comprises a vehicle body, and a water spray ring, a detection mechanism, and a scraping mechanism are connected to the vehicle body;

[0007] The detection mechanism includes a detection block, which is close to the inner wall of the tunnel. The scraping mechanism includes an annular brush, which is provided with a first bristle and a second bristle in an annular array. The diameter of the first bristle is larger than that of the second bristle, and the hardness of the second bristle is higher than that of the first bristle.

[0008] When the detection block is blocked by objects adhered to the inner wall of the tunnel and swings, the annular brush moves upward, and both the first bristles and the second bristles contact the inner wall of the tunnel.

[0009] Furthermore, the detection mechanism further includes a support rod, the support rod is connected to an arc-shaped cylinder, and the detection block is connected to the output end of the arc-shaped cylinder.

[0010] Furthermore, the detection mechanism further includes a box body, a slide plate is slidably connected to the box body, a tension spring is connected between the slide plate and the box body, and the box body is communicated with the arc cylinder.

[0011] Furthermore, the detection mechanism further comprises a driving cylinder, the driving cylinder being connected to the vehicle body, and an output end of the driving cylinder being directed toward the slide;

[0012] A pressure-sensitive switch for controlling the driving cylinder is provided at the port of the box body. When the arc-shaped cylinder is shortened more, the slide approaches and squeezes the pressure-sensitive switch, so that the driving cylinder extends and then shortens to reset the detection block.

[0013] Furthermore, the scraping mechanism also includes a nozzle, a sleeve is axially slidably connected to the nozzle, the annular brush is rotatably connected to the outer wall of the sleeve, an electric telescopic rod is connected to the vehicle body, the output end of the electric telescopic rod is connected to the sleeve, and when the detection block swings, the electric telescopic rod extends and then shortens.

[0014] Furthermore, the annular brush and the detection block are both provided in plurality, and the plurality of annular brushes and the plurality of detection blocks correspond to each other one by one and are arranged in a fan-shaped array on the vehicle body;

[0015] The water spray ring is arranged at the traveling end of the vehicle body, and the detection block is arranged between the water spray ring and the annular brush.

[0016] Furthermore, the scraping mechanism also includes four crescent blocks, which are arranged in a circular array at the port of the nozzle, and the four crescent blocks can be close to or away from each other. Moreover, when the four crescent blocks are close to each other, a conical cylinder is formed to increase the impact force of the water spray from the nozzle.

[0017] Furthermore, a conical ring is connected to the top of the sleeve, and wedge blocks are connected to the outer walls of the four crescent blocks, and the wedge blocks are fitted with the inner walls of the conical ring.

[0018] Furthermore, a slider is connected to the bottom of the crescent block, and a sliding groove that cooperates with the slider is opened on the port of the nozzle.

[0019] Furthermore, the bottom of the vehicle body is provided with moving wheels and the vehicle travels in the tunnel via the moving wheels.

[0020] The beneficial effects of the present invention are analyzed as follows:

[0021] An intelligent flushing device for an intercity railway tunnel comprises a cleaning vehicle, which comprises a vehicle body connected to a water spray ring, a detection mechanism, and a scraping mechanism; the detection mechanism comprises a detection block, which is close to the inner wall of the tunnel; the scraping mechanism comprises an annular brush, which is provided with first and second bristles in an annular array; the first bristles have a larger diameter than the second bristles, and the second bristles have a higher hardness than the first bristles; when the detection block is blocked by adhesions on the inner wall of the tunnel and swings, the annular brush moves upward, and both the first and second bristles contact the inner wall of the tunnel.

[0022] During use, water is sprayed onto the tunnel wall through the water spray ring to flush the tunnel wall. The detection mechanism is used to detect whether there is any foreign matter attached to the tunnel wall after flushing. The detection mechanism detects the cleanliness of the tunnel wall by setting a detection block. The detection block is close to the tunnel wall but not in contact with it. When there is foreign matter on the tunnel wall, the foreign matter will protrude from the surface of the tunnel wall, so that the detection block will be blocked by the foreign matter when it moves with the vehicle body. At this time, when the position sensor detects that the detection block is moving relative to the vehicle body, the annular brush will move up. At this time, the first bristles and the second bristles on the annular brush are in contact with the tunnel wall. Due to the high hardness of the second bristles, the second bristles can brush off the foreign matter on the tunnel wall at this time. When the detection block does not move, the annular brush does not rise at this time, so that only the first bristles clean the tunnel wall, avoiding the long-term contact of the second bristles with the tunnel wall and causing a large degree of wear on the tunnel wall. Through the cooperation of the above structure, the debris on the tunnel wall is adaptively cleaned, so that there is no need to manually check the cleanliness of both sides of the tunnel wall again after one flush, so that the adhesion on both sides of the tunnel wall can be completely cleaned after one flush.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] like Figures 1-6As shown, an intelligent flushing device for an intercity railway tunnel includes a cleaning vehicle 100, which includes a vehicle body 110, to which a water spray ring 120, a detection mechanism 200, and a scraping mechanism 300 are connected; the detection mechanism 200 includes a detection block 230, which is close to the inner wall of the tunnel; the scraping mechanism 300 includes an annular brush 330, on which a first bristle 331 and a second bristle 332 in an annular array are provided, wherein the diameter of the first bristle 331 is larger than that of the second bristle 332, and the hardness of the second bristle 332 is higher than that of the first bristle 331; when the detection block 230 is blocked by adhesion on the inner wall of the tunnel and swings, the annular brush 330 moves upward, and the first bristle 331 and the second bristle 332 both contact the inner wall of the tunnel.

[0036] The working mechanism of the flushing device provided in this embodiment is as follows:

[0037] When in use, water is sprayed onto the tunnel wall through the water spray ring 120 to flush the tunnel wall. The detection mechanism 200 is used to detect whether there are still foreign objects adhering to the tunnel wall after flushing. The detection mechanism 200 detects the cleanliness of the tunnel wall by setting a detection block 230. The detection block 230 is close to the tunnel wall but does not touch it. When there is foreign matter on the tunnel wall, the foreign matter will protrude from the surface of the tunnel wall, so that when the detection block 230 moves with the vehicle body 110, it will be blocked by the foreign matter. At this time, when the position sensor detects that the detection block 230 moves relative to the vehicle body 110, the annular brush 330 will move up. At this time, the first The first bristle 331 and the second bristle 332 are both in contact with the tunnel wall. Due to the high hardness of the second bristle 332, the second bristle 332 can brush off foreign matter on the tunnel wall. When the detection block 230 does not move, the annular brush 330 does not rise, so that only the first bristle 331 cleans the tunnel wall, avoiding the second bristle 332 from contacting the tunnel wall for a long time and causing a large degree of wear on the tunnel wall. Through the cooperation of the above structure, the debris on the tunnel wall is adaptively cleaned, so that there is no need to manually re-check the cleanliness of both sides of the tunnel wall after one flushing, so that the adhesion on both sides of the tunnel wall can be thoroughly cleaned after one flushing;

[0038] The top of the car body corresponding to the top of the tunnel wall is not provided with a scraping mechanism 300 and a detection mechanism 200, thereby avoiding other devices such as the contact network. In addition, a nozzle is further provided at the bottom of the car body 110, and the nozzle at the bottom of the car body 110 cleans the railway track bed;

[0039] A visual sensor is also provided on the vehicle body 110 near the scraping and washing mechanism 300 and the water spray ring 120. When the visual sensor detects that the scraping and washing mechanism 300 or the water spray ring 120 moves to various switch positions, the control system controls the water spray ring 120 or the scraping and washing mechanism 300 to stop spraying water, thereby preventing these switches from getting wet.

[0040] Among the optional methods of this embodiment, the more preferred ones are:

[0041] The detection mechanism 200 further includes a support rod 210 , to which an arc-shaped cylinder 220 is connected, and a detection block 230 is connected to an output end of the arc-shaped cylinder 220 .

[0042] The support rod 210 can move axially relative to the vehicle body 110, so that the support rod 210 can drive the detection block 230 to move closer to or away from the tunnel wall, thereby being suitable for cleaning tunnel walls of different diameters. The movement of the support rod 210 can be driven by a hydraulic rod. When the detection block 230 is blocked by foreign objects on the tunnel wall, the detection block 230 can push the arc cylinder 220, thereby causing the arc cylinder 220 to retract.

[0043] Regarding how to reset the detection block 230, specifically:

[0044] The detection mechanism 200 further includes a box body 240 , in which a slide plate 250 is slidably connected. A tension spring 260 is connected between the slide plate 250 and the box body 240 . The box body 240 is in communication with the arc cylinder 220 .

[0045] When the detection block 230 pushes the arc cylinder 220, the gas in the arc cylinder 220 is transferred to the box body 240. At this time, the air pressure in the box body 240 increases, causing the slide plate 250 to slide toward the outside of the box body 240, thereby stretching the tension spring 260. When the detection block 230 no longer contacts the obstruction, the tension of the tension spring 260 is restored, causing the arc cylinder 220 to extend, thereby resetting the detection block 230.

[0046] In addition, the provision of the tension spring 260 provides resistance to the swing of the detection block 230 , so that the detection block 230 can resist the obstruction of loose adherents on the tunnel wall, so that the loose adherents can be removed by the detection block 230 .

[0047] Among the optional methods of this embodiment, the more preferred ones are:

[0048] The detection mechanism 200 also includes a driving cylinder 280, which is connected to the vehicle body 110, and the output end of the driving cylinder 280 is facing the slide plate 250; a pressure-sensitive switch 270 for controlling the driving cylinder 280 is provided at the port of the box body 240. When the degree of shortening of the arc cylinder 220 increases, the slide plate 250 approaches and squeezes the pressure-sensitive switch 270, thereby driving the cylinder 280 to extend and then shorten to reset the detection block 230.

[0049] The nozzle 310 has a port close to the tunnel wall, and the nozzle 310 can also move axially relative to the vehicle body 110, so that the distance between the nozzle 310 and the tunnel wall can be adjusted. The movement of the nozzle 310 can be adopted in the same manner as the support rod 210. After adjustment, the distance between the nozzle 310 and the tunnel wall is smaller than the distance between the water spray ring 120 and the tunnel wall. When the swing angle of the detection block 230 is large, it means that the length of the foreign matter protruding from the tunnel wall is longer. At this time, the arc cylinder 220 is shortened more, thereby allowing more air to be introduced into the box body 240, so that the slide plate 250 abuts against the pressure-sensitive switch 270, at which time the driving cylinder 280 extends, thereby driving the cylinder 280 to push the slide 250 to reset, so that the gas in the box body 240 flows back into the arc cylinder 220, so that the arc cylinder 220 pushes the detection block 230 to reset. At this time, the detection block 230 can push and cut off the foreign matter, thereby avoiding the foreign matter protruding too much and causing the subsequent nozzle 310 to be blocked. In addition, it should be noted that the distance between the water spray ring 120 and the tunnel wall is large enough, and thus the water spray ring 120 will not be blocked by foreign matter on the tunnel wall.

[0050] Regarding the structure of the scraping mechanism 300, specifically:

[0051] The scraping mechanism 300 also includes a nozzle 310, to which a sleeve 320 is axially slidably connected, and an annular brush 330 is rotatably connected to the outer wall of the sleeve 320. An electric telescopic rod 340 is connected to the vehicle body 110, and the output end of the electric telescopic rod 340 is connected to the sleeve 320. When the detection block 230 swings, the electric telescopic rod 340 extends and then shortens.

[0052] The position sensor is used to control the extension and retraction of the electric telescopic rod 340. When the electric telescopic rod 340 is extended, the sleeve 320 is driven to move the annular brush 330 upward, thereby shortening the distance between the annular brush 330 and the tunnel wall. In addition, when the length of the nozzle 310 is adjusted, the electric telescopic rod 340 is also synchronously extended and retracted to ensure that the annular brush 330 can always be located at the end position of the nozzle 310. After the electric telescopic rod 340 controlled by the position sensor is extended, the electric telescopic rod 340 is shortened and reset when the annular brush 330 moves over the foreign object position.

[0053] Among the optional methods of this embodiment, the more preferred ones are:

[0054] There are multiple annular brushes 330 and multiple detection blocks 230, which correspond one to one and are arranged in a fan-shaped array on the vehicle body 110; the water spray ring 120 is set at the moving end of the vehicle body 110, and the detection block 230 is set between the water spray ring 120 and the annular brush 330.

[0055] By setting up multiple annular brushes 330 and detection blocks 230, the interior of the tunnel wall can be cleaned on a large scale. The detection block 230 is set between the water spray ring 120 and the annular brush 330, so that after the water spray ring 120 flushes the tunnel wall, the detection block 230 promptly detects the flushed tunnel wall, and after the detection, the movement of the annular brush 330 is adaptively controlled to enhance the cleaning effect.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] The scraping mechanism 300 also includes four crescent blocks 360, which are arranged in a circular array at the end of the nozzle 310. The four crescent blocks 360 can be close to or far away from each other. Moreover, when the four crescent blocks 360 are close to each other, a conical cylinder is formed to increase the impact force of the water spray from the nozzle 310.

[0058] When the annular brush 330 moves upward, the four crescent blocks 360 are synchronously moved close to form a conical tube. This conical tube causes the nozzle of the nozzle 310 to shrink, thereby increasing the water pressure sprayed by the nozzle 310, so that foreign matter on the tunnel wall is impacted by high-pressure water, and combined with the cleaning of the second bristles 332, the cleaning effect of the tunnel wall is guaranteed.

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] The top of the sleeve 320 is connected to a conical ring 350 , and the outer walls of the four crescent blocks 360 are connected to wedge blocks 370 , which fit into the inner wall of the conical ring 350 .

[0061] When the sleeve 320 moves upward, the conical ring 350 connected to the sleeve 320 moves upward synchronously. At this time, the inner wall of the conical ring 350 pushes the wedge block 370, so that the four crescent blocks 360 connected to the wedge block 370 are synchronously approached. The conical ring 350 and the wedge block 370 can be magnetically attracted to each other, so that when the conical ring 350 moves downward, the wedge block 370 can be driven to reset by magnetic attraction.

[0062] Among the optional methods of this embodiment, the more preferred ones are:

[0063] The bottom of the crescent block 360 is connected to a slider 361 , and the end of the nozzle 310 is provided with a sliding groove that cooperates with the slider 361 .

[0064] The setting of the slider 361 provides guidance for the movement of the crescent blocks 360, ensuring that the four crescent blocks 360 can move along a fixed direction to be combined or dispersed.

[0065] Among the optional methods of this embodiment, the more preferred ones are:

[0066] The bottom of the vehicle body 110 is provided with moving wheels 111 and the vehicle body 110 moves in the tunnel via the moving wheels 111 .

[0067] The vehicle body 110 is moved in the tunnel by being towed by the vehicle head, and a power source may also be provided on the vehicle body 110 for independent movement. In addition, all components of the flushing device of this embodiment are manufactured using a waterproof process.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
