Description

Technical Field

[0001] The utility model relates to the technical field of tunnel safety operation, in particular to a tunnel vault thermal insulation and deicing system. Background Art

[0002] Frost damage is a common tunnel disease. The cyclic occurrence of frost damage will cause cracks in the tunnel lining. Due to cracks in the tunnel lining, groundwater leaking from the surrounding rock can seep out through the cracks and freeze into ice at the outlet of the seepage point due to the low temperature, which will further cause deformation of the lining and even spalling, seriously reducing the bearing capacity and ultimately leading to instability and damage of the lining structure.

[0003] At present, heat preservation and anti-freezing are the basic prevention and control measures for freezing damage in tunnels in cold regions. For example, ice melting devices can be installed in the tunnel vault area where cracks have already occurred and icicles can be frequently formed to melt the icicles. However, if ice melting devices are installed on the tunnel vault, the icicles will melt into water and fall onto the track, causing the track to freeze when the temperature drops again, which will also seriously affect driving safety.

The scraping device 5 is located at the top of the box body 4, and the scraping device 5 includes a scraping frame 51, and the scraping frame 51 is fixed to the box body 4 through an elastic device 52 at the bottom. The scraping frame 51 includes two vertical scrapers 511 and a horizontal plate 512, and the two vertical scrapers 511 are fixed to the top of the horizontal plate 512 in a V shape. The horizontal plate 512 between the two vertical scrapers 511 is hollowed out to form a drop channel, and a raindrop sensor 82 is provided on the top of the box body 4, and the raindrop sensor 82 is located below the drop channel.

[0049] A temperature sensor 81 is provided on the side of the box body 4 .

[0050] A partition 41 is provided in the box body 4 and divides the box body 4 into an upper cavity 43 and a lower cavity 42. The scraping device 5 and the heating device 6 are located in the upper cavity 43. A power supply 9 is provided in the lower cavity 42.

[0051] like Figure 1-6 In the embodiment of the present invention, the support frame 1 includes an arc-shaped guide rail frame 11, which is a track commonly used in some existing automation equipment, such as Figure 4 As shown, the shape of the arc guide frame 11 needs to be the same as the shape of the inner wall of the tunnel, which is semicircular. The arc guide frame 11 is fixed at the bottom of the tunnel. The arc guide frame 11 is parallel to the inner wall of the tunnel and a distance is reserved between the arc guide frame 11 and the inner wall of the tunnel for the walking sliding seat 2 to move. The walking sliding seat 2 can slide forward and backward along the arc guide frame 11. The walking sliding seat 2 drives the deicing mechanism 3 to move while moving. The deicing mechanism 3 is as shown in FIG. Figure 3 and Figure 4 As shown, it includes a deicing bracket 4, a scraping device 5, a heating device 6, and a control system 7, a detection module 8 and a power supply 9 arranged inside the deicing mechanism 3. Specifically, as Figure 5 As shown, the box body 4 is a square shell with an upper opening, a hollow middle part of the shell, and a partition 41 arranged in the middle to divide the box body 4 into a lower cavity 43 and an upper cavity 42. The control system 7 and the power supply 9 are arranged in the lower sealed cavity. The control system 7 is used to communicate with the external control room and the detection module 8 for information efficiency and control the forward and backward movement of the walking sliding seat 2. The detection module 8 includes a temperature sensor 81 for detecting temperature and a raindrop sensor 82 for detecting whether there is water. The temperature sensor 81 is used to detect the temperature in the current tunnel and transmit the temperature information to the control room and the control system 7. The raindrop sensor 82 generally adopts a piezoelectric raindrop sensor 82, which is installed below the scraping device 5. The scraping device 5 is used to scrape water or ice on the inner wall of the tunnel. Figure 3As shown, the scraping device 5 in this embodiment is arranged above the upper cavity 42, and the scraping device 5 includes a scraping frame 51 and an elastic device 52. The top of the scraping frame 51 abuts against the inner wall of the tunnel to remove the hanging ice from the inner wall of the tunnel. An elastic device 52 is provided between the scraping frame 51 and the box body 4. In this embodiment, the elastic device 52 includes two springs, and two vertical plugs for fixing the springs are provided on the partition 41. The spring is installed in the vertical plug, and the upper end of the spring is fixedly connected to the scraping frame 51, so that the scraping frame 51 can avoid causing greater damage to the inner wall of the tunnel, while ensuring that the inner wall of the tunnel can be A force sufficient to scrape the hanging ice is applied, and a dropping channel for the hanging ice to fall is provided in the scraping frame 51, and a raindrop sensor 82 is provided below the dropping channel, so that when the scraping device 5 passes through the water seepage point of the tunnel, if there is no water on the inner wall of the tunnel, the walking sliding seat 2 will continue to move forward, and if there is water on the inner wall of the tunnel or ice is scraped off by the scraping frame 51, it will fall on the raindrop sensor 82, and the raindrop sensor 82 will transmit this information to the control system 7 and the main control room, and the control system 7 will record the current position of the walking sliding seat 2 and turn on the heating device 6, which is provided below the scraping device 5 and fixed on the box body 4, as shown in FIG. Figure 3 As shown, in this embodiment, the heating device 6 is located on one side of the elastic device 52, and the heating device 6 transfers heat upward from the drop channel, which can accelerate the evaporation of water and the melting of residual hanging ice, thereby achieving a better cleaning effect. The utility model detects the real-time temperature through the temperature sensor 81. When the temperature is close to or below zero degrees, the control system 7 controls the walking sliding seat 2 to drive the deicing mechanism 3 to move along the arc guide frame 11, and the scraping mechanism pre-cleans the seepage points on the inner wall of the tunnel where water seepage may occur, wipes off the seepage on the inner wall of the tunnel, and removes the seepage before ice is generated, thereby fundamentally solving the problem of hanging ice. The rainwater sensor can detect whether there is water seepage when the scraping device 5 passes through the seepage point, so the device can be operated regularly to check in advance whether the seepage point is leaking. After detecting that the leaking point is leaking, the utility model can heat the leaking point through the heating device 6, evaporate the seepage or melt the hanging ice by heat.

[0052] As a further description of the scraping frame 51, Figure 4 and Figure 5As shown, the scraping frame 51 includes two vertical scrapers 511 and a horizontal plate 512 for connecting and supporting. The vertical scrapers 511 are V-shaped, and the drop channel is located below between the two vertical scrapers 511. The vertical scrapers 511 are V-shaped and fixed on the horizontal plate 512. The front end of the horizontal plate 512 is provided with a V-shaped slot. The spring connects the two sides of the rear end of the horizontal plate 512. The slot is below the drop channel. The heating device 6 is provided below the rear end of the horizontal plate 512. When the walking sliding seat 2 moves forward, water and ice will follow the vertical scrapers 511 to concentrate at the tip of the V shape, and move downward along the vertical scrapers 511 into the drop channel to ensure that they can fall on the water drop sensor.

[0053] As a specific description of the walking sliding seat 2, Figure 2 As shown, the walking sliding seat 2 includes a sliding frame 21, a walking wheel 22, a walking gear 23 and a servo motor 24. The outer side surface of the arc guide frame 11 is a sliding surface, and the inner side surface of the arc guide frame 11 is provided with a gear. The sliding frame 21 is slidably matched with the vertical side surface of the arc guide frame 11. The sliding frame 21 is a hollow rectangular frame. The arc guide frame 11 passes through the hollow area of ​​the sliding frame 21. The walking wheel 22 and the walking gear 23 are both rotatably arranged in the sliding frame 21 and arranged on both sides of the arc guide frame 11. The side of the sliding frame 21 close to the sliding surface is provided with at least two walking wheels 22, and the side of the sliding frame 21 close to the inner side surface of the arc guide frame 11 is provided with at least two walking gears 23. The servo motor 24 is connected to the control system 7. The servo motor 24 is arranged on the sliding frame 21 and drives the walking gear 23 to rotate. In the prior art, the device that can move on the arc guide rail has been developed relatively well and is often used in some automation industries, so it is not described in detail.

[0054] Because the arc guide frame 11 needs to be installed with a walking sliding seat 2, the walking sliding seat 2 needs to pass through all the arc areas of the arc guide frame 11 when walking. The only position where it can be connected and fixed with the inner wall of the tunnel is the end area of ​​the arc guide frame 11, and the stability after installation and fixation cannot be guaranteed. Therefore, a fixing frame 12 is added, and the fixing frame 12 includes multiple connecting rods 121 and multiple fixing plates 122. The connecting rod 121 is L-shaped, one end of which is connected to the side of the arc guide frame 11, and the other end is connected to the fixing plate 122. The fixing plate 122 is a small arc plate, which can be attached to the inner wall of the tunnel and fixed to the inner wall of the tunnel by bolts. A sliding groove is provided on one of the sides of the sliding frame 21. When the connecting rod 121 is in the sliding groove and the sliding frame 21 moves along the arc guide frame 11 to the position of the connecting rod 121, the connecting rod 121 can pass through the sliding groove. This will not hinder the movement of the walking sliding seat 2, and can enhance the firmness of the support frame 1.

[0055] As a specific description of the heating device 6, Figure 6 As shown, the heating device 6 includes a blowing device 61 and a heating device 62. The heating device 62 generally adopts an electric heating element, such as a heating wire. The heating device 62 is connected to a power supply 9 located in the lower cavity 43. The heating device 6 is arranged on one side of the falling channel, generally below the rear end of the horizontal plate 512. The blowing device 61 is arranged between the heating device 62 and the falling channel.

[0056] The utility model detects the real-time temperature through a temperature sensor. When the temperature is close to or below zero degrees, the control system controls the walking sliding seat to drive the deicing mechanism to move along the arc-shaped guide rail frame. The scraping mechanism pre-cleans the water seepage points on the inner wall of the tunnel where water seepage may occur, wipes off the water seepage on the inner wall of the tunnel, and removes the water seepage before ice is formed, thereby fundamentally solving the problem of ice hanging.

[0057] The utility model can detect whether there is water seepage when the scraping device passes through the water seepage point through the rain sensor, so the device can be operated at a fixed time, so as to check in advance whether the water seepage point is leaking.

[0058] After the utility model detects the water leakage at the water leakage point, the water leakage point can be heated by the heating device, and the seepage water is evaporated or the hanging ice is melted by the heat.

[0059] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
