[0051] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0052] In view of the problems raised in the background technology, the following embodiments are proposed in this solution to solve them:

[0053] Please refer to Figures 1 to 5 This embodiment proposes a tunnel deicing device, which includes: a support assembly 1; the support assembly 1 is used to support the entire microwave heating device 2, so that the microwave heating device 2 can move along the support assembly 1 and heat a designated position.

[0054] The support assembly 1 is provided with a microwave heating device 2; that is, in this embodiment, the ice on the tunnel side wall is heated by microwave heating. The principle and implementation of microwave heating belong to the prior art and can be implemented by those skilled in the art, so it will not be described in detail here.

[0055] Specifically, the support assembly 1 is arranged on the side wall of the tunnel along the length direction of the tunnel, and the microwave heating device 2 is connected to the support assembly 1 in a sliding manner, and the microwave heating device 2 can slide along the length direction of the support assembly 1; the microwave heating device 2 is used to heat the ice on the side wall of the tunnel. Specifically, the support assembly 1 includes a support rod, and the microwave heating device 2 is slidably arranged on the support rod. The support rod can be a round rod or a square rod. When the support rod is a square rod, the microwave heating device 2 can be limited to rotate around the support rod. When the support rod is a round rod, the number of walking wheels on the walking assembly 21 on the microwave heating device 2 should be at least two, and the two walking wheels are respectively located on the upper and lower sides of the support rod.

[0056] The support assembly 1 is provided with a temperature sensor 3, a humidity sensor 4 and a controller 6. The controller 6 is used to control the movement of the microwave heating device 2 according to the detection results of the temperature sensor 3 and the humidity sensor 4, and to heat the target position.

[0057] A pipe 11 is provided in the support assembly 1 , and a plurality of outlet holes 12 are provided on a side of the pipe 11 facing the tunnel side wall. The pipe 11 can spray a salt solution onto the tunnel side wall to lower the freezing point of water on the tunnel side wall.

[0058] In the above way, ice on the side wall of the tunnel can be cleared. In particular, ice can be cleared without heating within a certain temperature range to avoid damage to the tunnel caused by repeated heating. For example, when the temperature is between -10°C and 0°C, ice formation can be avoided by lowering the freezing point. Since the freezing point of saturated salt solution can be as low as about -22°C, spraying salt solution can be used to avoid ice formation between -10°C and 0°C. When the temperature is too low, the ice is heated by microwave heating.

[0059] In the specific implementation, it also includes a drainage ditch 5, which is fixedly arranged at the bottom of the tunnel side wall. A heating component 51 is embedded in the drainage ditch 5. The heating component 51 is used to heat the water in the drainage ditch 5 to prevent the water in the drainage ditch 5 from freezing. The function of the drainage ditch 5 is first to recover the salt solution, second to prevent the ice from accumulating in the tunnel after melting, causing it to freeze again at the bottom of the tunnel, and third, through the drainage ditch 5, the air with high humidity in the tunnel is taken away at the same time.

[0060] The bottom of the drainage groove 5 is provided with a drainage hole 52, and the drainage hole 52 is arranged along the length direction of the drainage groove 5, and the drainage hole 52 is connected to the drainage groove 5 through a connecting hole. The setting of the drainage hole 52 is mainly to prevent excessive evaporation of water into water vapor in the tunnel during the drainage process. In the specific implementation, one end of the drainage hole 52 is closed, and a fan is set at the other end to quickly exhaust air. In the specific implementation, a second solenoid valve can be set at the connecting hole. For the first target position and the second target position, the second solenoid valve is opened, and the air at the first target position and the second target position is discharged through the fan, and the water vapor is taken out.

[0061] In a specific implementation, it also includes a walking component 21 arranged on the microwave heating device 2, and the walking component 21 is provided with a walking wheel 22, the walking wheel 22 is rotatably connected to the walking component 21, and the walking wheel 22 abuts against the side wall of the tunnel; a pressure sensor is provided on the rotating shaft of the walking wheel 22; in a specific implementation, the walking component 21 is provided with a driving motor, and the driving motor is transmission-connected to the walking wheel 22, so that the driving motor drives the walking wheel 22 to rotate, thereby realizing the movement of the walking component 21.

[0062] According to the detection result of the pressure sensor, the microwave heating device 2 is controlled to heat the position where the walking wheel 22 is located. In some practical applications, depending on the environment, the walking assembly 21 may be frozen or ice may block the rolling of the walking wheel 22, causing a malfunction. When the walking wheel 22 is blocked, the pressure on the walking wheel 22 increases. For those skilled in the art, the walking mechanism belongs to the prior art and can be implemented by those skilled in the art. The specific structure thereof will not be described in detail in this embodiment.

[0063] Specifically, the controller 6 is used to obtain the detection result of the pressure sensor in real time when controlling the walking wheel 22 to walk; when the detection result of the pressure sensor is greater than the setting and the walking component 21 cannot move; the microwave heating device 2 is controlled to heat the position where the walking wheel 22 is located; if the walking component 21 still cannot move after heating, an alarm signal is generated through the controller 6, and if the walking component 21 can move after heating, the position is added as the target position.

[0064] Specifically, the position where the walking wheel 22 is located is heated by the microwave heating device 2 to remove the ice there. At the same time, the position is heated up and down by the microwave heating device 2 to remove the ice at the position. In this process, the change in the detection result of the humidity sensor near the position can be used to determine whether the ice at the position has melted. If the detection result of the humidity sensor increases, it means that the ice at the position is melting. When the detection result of the humidity sensor at the position remains unchanged, it means that there is no ice at the position. At this time, an alarm can be issued to the outside world through the controller; if the humidity at the position decreases, it means that the ice has completely melted. If the walking component 21 can move normally after heating, the position is added as the target position.

[0065] In a specific implementation, in order to determine the water seepage position in the tunnel, the detection results of the humidity sensor 4 are multiple, and the multiple humidity sensors 4 are evenly distributed along the length direction of the support assembly 1. For example, in a specific implementation, the distance between adjacent humidity sensors 4 is 0.5 meters. Specifically, the controller 6 obtains the detection result of the temperature sensor 3. When the result detected by the temperature sensor 3 is greater than the first temperature value, in a specific implementation, when the first temperature value is 5°C, the detection results of each humidity sensor 4 are intermittently obtained, and the first target position is determined according to the detection result. For example, the detection result of the humidity sensor 4 is obtained once every week or 5 days. In actual application, the controller is also used to analyze and process the detection results of the temperature sensor. For example, when the detection results of the temperature sensor continuously decrease in multiple consecutive detection cycles, it means that the temperature is decreasing. When the most recent temperature is lower than 5°C, the salt solution in the pipe 11 can be discharged first, and then hot air can be introduced to promote the evaporation of water at the target position. At the same time, air is pumped out of the tunnel through the drainage hole 52 in the drainage groove 5 to reduce the humidity of the air in the tunnel. In some implementations, there may be multiple support assemblies 1, arranged in parallel from top to bottom. When used, the top one can pump air out of the tunnel, and one or more of the lower ones can blow air toward the first target position. The blown air can be the same as the ambient temperature or slightly higher than the ambient temperature. In this way, the water in the tunnel can evaporate quickly before the temperature drops to 0°C to avoid freezing.

[0066] In a specific implementation, when the detection result of the temperature sensor 3 is between the first temperature value and the second temperature value, the detection result of each humidity sensor 4 is obtained in real time, and the second target position is determined according to the detection result of the humidity sensor 4; the second temperature value is 0°C, when the detection result of the temperature sensor 3 is between the first temperature value and the second temperature value, through the analysis of historical temperature data, if the temperature has dropped continuously recently, the salt solution in the pipe 11 is first discharged, and then hot air is introduced to promote the evaporation of water at the target position, and at the same time, air is drawn out of the tunnel through the drainage hole 52 in the drainage groove 5 to reduce the humidity of the air in the tunnel.

[0067] In a specific implementation, when the detection result of the temperature sensor 3 is between the second temperature value and the third temperature value, the salt solution is sprayed on the second target position. In a specific implementation, the third temperature value can be about -10°C. Within this temperature range, the freezing point of water on the side wall of the tunnel can be lowered by spraying a salt solution to prevent freezing. Specifically, a saturated salt solution can be sprayed. In a specific implementation, a three-way valve can be provided at the entrance of the pipeline 11 to allow the air in the hot air unit or the liquid in the saturated salt solution pool to enter the pipeline 11. Specifically, the three-way valve is a solenoid valve three-way valve, which is electrically connected to the controller. By controlling the solenoid three-way valve, hot air or saturated salt solution is introduced. In practical applications, the saturated salt solution can also be heated to 20°C and then sprayed. When spraying the second target position, it is only necessary to control the solenoid valve on the pipeline 11 corresponding to the second target position to open.

[0068] When the detection result of the temperature sensor 3 is lower than the third temperature value, the microwave heating device 2 is controlled to move to the first target position and the second target position, and heat the first target position and the second target position respectively. At this time, the ice forming speed is too fast, and microwave heating is required. Since microwaves can heat the inside of the ice, it is beneficial to reduce the adhesion between the ice and the tunnel side wall, so as to achieve rapid shedding of ice.

[0069] After deicing the first target position and the second target position, hot air is blown into the first target position and the second target position through the pipe 11 below, specifically, the air at 20-30°C, and the water vapor is discharged at the top of the first target position or the second target position. Water and air are discharged through the drainage holes 52 on the drainage groove 5 to reduce the retention of air with high humidity in the tunnel.

[0070] In a specific implementation, the method for determining the first target position and the second target position is:

[0071] The position of each humidity sensor 4 in the length direction of the tunnel is determined.

[0072] It is determined whether the detection result of each humidity sensor 4 is greater than a set humidity value. If it is greater than the set humidity value, it indicates that water seepage exists near the location of the humidity sensor 4.

[0073] For multiple humidity sensors 4 whose detection results are greater than the set humidity value and are continuous, the detection results are fitted to determine the position with the highest humidity, and the position is determined as the first target position or the second target position. The position with the highest humidity is the water seepage position. It is also the position that is prone to ice formation. When deicing, this position needs to be treated with emphasis.

[0074] In a specific implementation, the salt solution is a saturated salt solution; when the detection result of the temperature sensor 3 is lower than the third temperature value, the salt solution in the pipe 11 is discharged, and hot air is introduced to the first target position and the second target position through the pipe 11. In this application, hot air refers to air higher than the ambient temperature.

[0075] A first solenoid valve 13 is disposed in each outlet hole 12 on the pipeline 11 . The first solenoid valve 13 is used to open or close according to a signal from the controller 6 so that the salt solution or hot air can flow to a target location.

[0076] Please refer to Figure 4 The present invention also proposes a tunnel deicing system, including a controller 6, a microwave heating device 2, a support component 1, a temperature sensor 3, a humidity sensor 4, a pump, a hot air unit and a walking component 21.

[0077] The microwave heating device 2 , the supporting assembly 1 , the temperature sensor 3 , the humidity sensor 4 , the pump, the salt solution tank, the hot air unit and the walking assembly 21 are all electrically connected to the controller 6 .

[0078] The controller 6 determines the target position according to the detection results of the temperature sensor 3 and the humidity sensor 4, and controls the first solenoid valve 13, the travel assembly 21, the pump, the microwave heating device 2, and the hot air unit to de-ice the target position.

[0079] In specific implementation, the tunnel deicing system achieves deicing at the target location by the following method:

[0080] The detection result of the temperature sensor 3 is obtained; the detection result of the temperature sensor 3 is determined in the interval; when the detection result of the temperature sensor 3 is greater than the first temperature value, the detection results of the plurality of humidity sensors 4 are used to determine the first target position; when the detection result of the temperature sensor 3 is between the first temperature value and the second temperature value, the detection results of the plurality of humidity sensors 4 are used to determine the second target position; when the detection result of the temperature value is between the second temperature value and the third temperature value, the first electromagnetic valve 13 of the control part is opened to spray the salt solution to the first target position and the second target position; when the detection result of the temperature value is lower than the third temperature value, the travel component 21 is controlled to move to the first target position and the second target position respectively, and the microwave heating device 2 fixedly connected to the travel component 21 is controlled to heat the first target position and the second target position; the first electromagnetic valve 13 of the control part is opened to heat the first target position and the second target position through the hot air unit.

[0081] The working process of the tunnel deicing system proposed in the present invention can also refer to the aforementioned part, which will not be repeated here.

[0082] It should be pointed out that in the present application, the hot air unit heats the air through an electric heating wire, which is a prior art for those skilled in the art and can be implemented by those skilled in the art, and this application will not elaborate on this.

[0083] In specific implementation, the air inlet and outlet and the spraying of the salt solution are driven by a pump, and the pump is controlled by a controller. This belongs to the prior art and can be implemented for those skilled in the art.

[0084] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings.
