Description

Technical Field

[0001] The present invention mainly relates to the technical field of tunnel railway protection, and in particular to a railway tunnel ice melting device and system. Background Art

[0002] Due to the gaps between the arches on the top wall of the tunnel, varying degrees of leakage, dripping, and seepage are a common problem in railway tunnels. When the temperature is low in winter, the arches and side walls in the railway tunnel condense into icicles due to seepage. When the length of the arch icicles is too long and invades the discharge area of ​​the high-voltage contact network erected in the railway tunnel, discharge will occur, causing the traction substation to trip and power off, interrupting the train operation. In severe cases, the load-bearing cables and contact network equipment will be burned, posing a great hidden danger and threat to the railway power supply safety and transportation safety.

[0003] Artificial deicing is the method used by most railway tunnels to de-ice. Deicers have to use iron pickaxes to knock off the icicles on the top of the tunnel one by one. This method is performed several times a day in winter, and each operation lasts for a long time. The tunnel vault is high and the wind force in the tunnel is strong, which makes this method difficult to work, the environment is harsh, and it is accompanied by great danger. Therefore, developing a safe and effective deicing method to replace artificial deicing has good application prospects and practical significance.

[0004] At present, the alternative to manual deicing is thermal deicing, which converts electrical energy into thermal energy through electric heating belts, and realizes automatic heating and temperature control with temperature control devices, and achieves deicing effect by increasing the temperature. Although this method can effectively eliminate icicles, it is not economical due to the large number of tunnels and the high density of ice points, and the required thermal energy consumption is huge, so the current utilization rate is not high. For example, in the patent application with application number 201320135646.1, when the ambient temperature in the tunnel is below zero or the temperature of the roof itself is too low, the temperature controller starts the heating switch and starts deicing; in winter, the heating element is basically always enabled, which consumes too much energy.

[0009] Preferably, a walking module is provided inside the right side plate, and the walking module includes an arc-shaped electric guide rail, on which a slider slides, and the slider is connected to the two placement blocks by connecting arm rings, and arc bars are provided at the upper and lower ends of the arc-shaped electric guide rail, respectively, and the side of the arc bar facing the power rod is a wavy surface, and the power rod is slidably installed on the wavy surface of the arc bar.

[0010] Preferably, the temperature control module also includes a plurality of rotating gears arranged inside the left side plate, each rotating gear is connected to a driving rod through a chain sprocket transmission, the driving rod extends into the cylindrical groove and is connected to the insulation sleeve, a movable rack slides back and forth inside the left side plate, the movable rack is meshed with the rotating gear, a telescopic sleeve frame is installed on the upper end of the movable rack, and the telescopic sleeve frame is slidably connected to one of the power rods.

[0011] Preferably, the temperature control module is connected to the melting module, and the melting module includes a heat storage tube arranged inside the right side plate. Each cylindrical groove is connected to the heat storage tube through a connecting pipe, a ventilation pipe is arranged on one side of each power rod, and a fan is arranged at one end of each ventilation pipe. The fan is connected to the heat storage tube through a hose, and a plurality of air nozzles are installed on the U-groove plate frame, and each air nozzle is connected to the ventilation pipe.

[0012] Preferably, the temperature control module further includes a temperature sensor arranged inside the left side panel.

[0013] A railway tunnel de-icing system is applicable to any railway tunnel de-icing device, comprising: a central control, a temperature control module, a melting module, a de-icing module and a travel module, wherein the electrical components of each module are controlled by the central control; Among them, the central control is set inside the left side panel; the temperature control module is used to obtain the tunnel temperature data to determine whether to send a control signal to control the heating of the heating element; the melting module is used to obtain the current ice thickness to adjust the fan speed; the deicing module is used to crush the ice layer; the walking module controls the movement of the deicing module and provides deicing power for the deicing module.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) When the de-icing module is moving, if the ice layer is thin, that is, the rolling rod does not contact the ice layer, as the placement block moves, the power rod continuously moves back and forth, so that the triangular plate moves with it, pushing the ice-breaking rod to move, and the ice-breaking rod inserts into the ice layer and peels it, quickly destroying the ice layer and crushing it; if the ice layer is thick, the ice-breaking rod directly inserts into the ice layer and peels it, which is easy to cause damage to the ice-breaking rod. Therefore, the material requirements for the ice-breaking rod are relatively high, and a powerful power source is also required to drive the ice-breaking rod to move. Both of these will undoubtedly increase the production cost and usage. The cost is low and it is only for a few cases, so the cost performance is low. The ice layer is thicker, that is, the rolling rod contacts the ice layer, so that the elastic telescopic rod contracts and pushes the adjusting rack to move. The adjusting rack moves through the gear ring to rotate the power rod, so that the ice-breaking rod is offset. In this way, the ice-breaking rod is inserted into the ice layer at an angle without too much resistance, and the thick ice layer is crushed in batches. Under the premise of avoiding damage to the ice-breaking rod and not using a high-power power source, the device ensures the effective breaking of the ice layer and the ice-melting effect, while reducing the production and use costs.

[0015] (2) As the de-icing module moves forward, the ice layer on the front half of the top arc plate surface is crushed and melted, while the ice layer on the back half of the top arc plate surface is not melted. At this time, if the heating element continues to heat the front half of the top arc plate surface, since there is no ice on the front half of the top arc plate surface, it will only interact thermally with the cold air flow, resulting in part of the heat of the hot air flow inside the heating groove being wasted on heating the cold air flow. When the device is in operation, as the de-icing module moves forward, the power rod and the telescopic sleeve will drive the moving rack to move, and the moving rack will drive the rotating gear to rotate. The rotating gear will drive the corresponding driving rod to rotate and let the insulation sleeve rotate half a circle, so that the insulation sleeve separates the contact groove and the cylindrical groove, that is, the heat will not flow to the area where the ice has melted, and the heat will flow to the unmelted area through the heat storage pipe, which can greatly reduce energy consumption.

[0016] (3) The temperature of the tunnel is detected by the temperature sensor. When the tunnel temperature is below zero, the device starts to operate. After the ice melting operation is completed, it will be activated again after an interval of one hour. The specific interval time depends on the temperature. The lower the temperature, the shorter the interval time. During the ice melting operation, the heating element heats the air inside the heating tank, so that the ice layer on the upper surface of the top arc plate is melted by the heat. After the temperature inside the heating tank rises to a certain level, the heating tank stops and keeps warm. Then, the de-icing module and the walking module are activated, that is, the arc-shaped electric guide rail is started, and the upper and lower placement blocks are driven to move through the connecting arm ring, so that the upper and lower groups of de-icing modules move. While moving, the upper and lower groups of de-icing modules are driven by the electric guide rail. Due to the special design of the wavy surface of the arc bar, the power rod continuously moves back and forth while moving, so that the triangular plate moves with it, pushing the ice-breaking rod to move. The ice-breaking rod inserts into the ice layer and peels it, quickly destroying and crushing the ice layer. At the same time, the fan draws the hot air flow inside the heating tank into the ventilation pipe and blows it out through the air nozzle to heat the surface of the ice layer. The ice layer is heated from top to bottom, further accelerating the ice melting efficiency. This device adopts a combination of thermal ice melting and mechanical de-icing. There is no need for the heating element to heat all the time, which greatly reduces energy consumption. At the same time, when heating the ice layer, the upper and lower parts are melted simultaneously to ensure the de-icing efficiency.

The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0022] Please refer to the attached Figure 1 - Figure 4As shown, a railway tunnel ice melting device comprises a top arc plate 101 and two side plates 102 installed on both sides of the top arc plate 101, and two upper and lower groups of deicing modules are arranged between the two side plates 102, and each group of the deicing modules comprises two arc grooves and a power rod 202, the two arc grooves are opposite to each other and are respectively arranged on the two side plates 102, and a placement block 201 is slidably arranged inside each arc groove, and the power rod 202 passes through the two placement blocks 201, and a plurality of equally spaced triangular plates 202 are arranged on the power rod 202. 03, an ice-crushing rod 204 is slidably mounted on the inclined surface of each triangular plate 203, and a plurality of the ice-crushing rods 204 are slidably connected to a fixed plate frame 205, and the fixed plate frame 205 is slidably connected to the power rod 202; an elastic telescopic rod 206 is mounted on each of the two placement blocks 201, and the other ends of the two elastic telescopic rods 206 are commonly connected to a U-groove plate frame 207, and a plurality of rolling rods 208 are mounted on the U-groove plate frame 207, and each rolling rod 208 is located in the area between two ice-crushing rods 204. An adjusting rack 209 is arranged on one of the placement blocks 201, and one end of the adjusting rack 209 is connected to the U-groove plate frame 207, and the other end thereof extends to the inside of the placement block 201 and is meshed with a gear ring, and the gear ring is located inside the placement block 201 and is slidably connected to the power rod 202, and one end of the adjusting rack 209 is arranged with a displacement sensor located inside the placement block 201.

[0023] The top arc plate 101 is fixed below the water leakage point on the top of the tunnel through the side plate 102. When deicing is performed, the deicing module starts to move under the drive of the walking module, the upper deicing module deices the ice layer on the arch, and the lower deicing module deices the surface of the top arc plate 101; during the movement, if the ice layer is thin, that is, the rolling rod 208 does not contact the ice layer, with the movement of the placement block 201, the power rod 202 continuously reciprocates left and right, so that the triangular plate 203 moves with it, pushing the ice crushing rod 204 to move, and the ice crushing rod 204 is inserted into the ice layer and peeled, quickly destroying the ice layer and crushing it; if the ice layer is thick, the ice crushing rod 204 is directly inserted into the ice layer and peeled, which is easy to cause damage to the ice crushing rod 204, so The material requirements of the ice crushing rod 204 are relatively high, and at the same time, a powerful power source is also required to drive the ice crushing rod 204 to move. Both of these will undoubtedly increase the production cost and the use cost, and it is only for a few cases, so the cost performance is low. The ice layer is thicker, that is, the rolling rod 208 contacts the ice layer, so that the elastic telescopic rod 206 contracts and pushes the adjustment rack 209 to move. The adjustment rack 209 moves through the gear ring to rotate the power rod 202, so that the ice crushing rod 204 is offset. In this way, when the ice crushing rod 204 is inserted into the ice layer, it is inserted obliquely without too much resistance. The thicker the ice layer, the larger the oblique insertion angle, and the thick ice layer is crushed in batches. The device ensures the effective breaking of the ice layer without damaging the ice crushing rod 204 and without using a high-power power source. Please refer to the attached pictures Figure 1 - Figure 6 As shown, a walking module is arranged inside the side plate 102 on the right side, and the walking module includes an arc-shaped electric guide rail 301, on which a slider slides, and the slider and the two placement blocks 201 are respectively connected through connecting arm rings 302, and arc bars 303 are respectively arranged at the upper and lower ends of the arc-shaped electric guide rail 301, and the side of the arc bar 303 facing the power rod 202 is a wavy surface 304, and the power rod 202 is slidably mounted on the wavy surface 304 of the arc bar 303. When the arc-shaped electric guide rail 301 is started, the upper and lower placement blocks 201 are driven to move through the connecting arm ring 302, thereby moving the upper and lower deicing modules. While moving, due to the special design of the wavy surface 304 of the arc bar 303, the power rod 202 continuously moves back and forth while moving.

[0024] Please refer to the attached pictures Figure 7 - Fig. 9As shown, a temperature control module is further provided inside the top arc plate 101 and the side plate 102, and the temperature control module includes a plurality of heating grooves equidistantly arranged inside the top arc plate 101, and each of the heating grooves is divided into a contact groove 402 in the upper half and a cylindrical groove 403 in the lower half, and the contact groove 402 is close to the upper end surface of the top arc plate 101, and a U-shaped insulation sleeve 404 is rotatably provided inside the cylindrical groove 403, and a heating element 401 is provided inside the insulation sleeve 404. The temperature control module also includes a plurality of rotating gears 405 arranged inside the left side plate 102, each of the rotating gears 405 is connected to a driving rod 406 through a chain sprocket transmission, the driving rod 406 extends to the inside of the cylindrical groove 403 and is connected to the heat insulation sleeve 404, and a movable rack 407 slides back and forth inside the left side plate 102, the movable rack 407 is meshed with the rotating gear 405, and a telescopic sleeve 408 is installed on the upper end of the movable rack 407, and the telescopic sleeve 408 is slidably connected to one of the power rods 202. The temperature control module is connected to the melting module, and the melting module includes a heat storage tube 409 arranged inside the right side plate 102. Each of the cylindrical grooves 403 is connected to the heat storage tube 409 through a connecting tube. A ventilation pipe 410 is arranged on one side of each power rod 202. A fan 411 is arranged at one end of each ventilation pipe 410. The fan 411 is connected to the heat storage tube 409 through a hose. A plurality of air nozzles 412 are installed on the U-groove plate frame 207, and each of the air nozzles 412 is connected to the ventilation pipe 410.

[0025] The heating element 401 can be an electric heating wire. When the device is running, the cylindrical groove 403 and the contact groove 402 are connected, and the heating element 401 heats the air inside the heating groove, so that the ice layer on the upper end surface of the top arc plate 101 is heated and melted. After the internal temperature rises to a certain level, it stops and keeps warm. The deicing module and the walking module are enabled, and the fan 411 is started at the same time, and the hot air flow inside the heating groove is attracted into the ventilation pipe 410 and blown out through the air nozzle 412 to heat the surface of the ice layer. The ice layer is heated up and down, and the ice melting efficiency is further accelerated. The greater the movement distance of the adjustment rack 209, the thicker the ice layer. The displacement sensor detects the movement amount of the adjustment rack 209. The central control adjusts the speed of the fan 411 according to the movement amount of the adjustment rack 209. The greater the movement amount of the adjustment rack 209, that is, the thicker the ice layer, the faster the speed of the fan 411, and the more hot air flow blown out of the air nozzle 412, so that the ice layer melts quickly; as the deicing module moves, the top arc plate After the ice layer on the front half of the surface of 101 is crushed and melted, the ice layer on the back half of the surface of the top arc plate 101 has not melted. At this time, if the heating element 401 continues to heat the front half of the surface of the top arc plate 101, because there is no ice on the surface of the front half of the top arc plate 101, it will only have thermal interaction with the cold air flow, resulting in part of the heat of the hot air flow inside the heating groove being wasted on heating the cold air flow. When the device is in operation, as the de-icing module moves, the power rod 202 and the telescopic sleeve 408 will drive the moving rack 407 to move, and the moving rack 407 will drive the rotating gear 405 to rotate. The rotating gear 405 drives the corresponding driving rod 406 to rotate and allows the insulation sleeve 404 to rotate half a circle, so that the insulation sleeve 404 separates the contact groove 402 and the cylindrical groove 403, that is, the heat will not flow to the area where the ice has melted, and the heat will flow to the unmelted area through the heat storage pipe 409, which can greatly reduce energy consumption.

[0026] The temperature control module also includes a temperature sensor disposed inside the left side plate 102. The temperature sensor detects the tunnel temperature. When the tunnel temperature is below zero, the device starts to operate. After the ice melting operation is completed, it is activated again after an interval of 2-6 hours. The specific interval time depends on the temperature. The lower the temperature, the shorter the interval time. A railway tunnel de-icing system, applicable to any one of the railway tunnel de-icing devices, comprising: a central control, a temperature control module, a melting module, a de-icing module and a travel module, wherein the electrical components of each module are controlled by the central control; Among them, the central control is arranged inside the left side panel. By setting up the central control, it is convenient to control the electrical components inside the device. The central control circuit can be realized through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0027] The temperature control module is used to obtain tunnel temperature data to determine whether to send a control signal to control the heating of the heating element; the melting module is used to obtain the current ice thickness to adjust the fan speed; the deicing module is used to crush the ice layer; the walking module controls the movement of the deicing module and provides deicing power for the deicing module. Specific operation method: When performing ice melting operation, the heating element 401 heats the air inside the heating tank, so that the ice layer on the upper end surface of the top arc plate 101 is heated and melted. When the temperature inside the heating tank rises to a certain level, the heating stops and heat preservation is performed; Next, the deicing module and the walking module are activated, that is, the arc-shaped electric guide rail 301 is activated, and the upper and lower placement blocks 201 are driven to move through the connecting arm ring 302, so that the upper and lower groups of deicing modules move. While moving, due to the special design of the wave surface 304 of the arc bar 303, the power rod 202 continuously moves back and forth while moving; During the movement of the de-icing module, if the ice layer is thin, that is, the rolling rod 208 does not contact the ice layer, as the placement block 201 moves, the power rod 202 continuously reciprocates back and forth, so that the triangular plate 203 moves with it, pushing the ice-breaking rod 204 to move, and the ice-breaking rod 204 inserts into the ice layer and peels, quickly destroying the ice layer and crushing it; if the ice layer is thick, the rolling rod 208 will contact the ice layer, so that the elastic telescopic rod 206 shrinks and pushes the adjustment rack 209 to move, and the adjustment rack 209 moves through the gear ring to rotate the power rod 202, so that the ice-breaking rod 204 is inserted into the ice layer obliquely, without too much resistance, and the thick ice layer is crushed in batches; When the de-icing module and the walking module are enabled, the fan 411 is started, and the hot air flow inside the heating tank is attracted into the ventilation pipe 410, and blown out through the air nozzle 412, so as to heat the surface of the ice layer. The ice layer is heated from top to bottom, and the ice melting efficiency is further accelerated. The greater the movement distance of the adjustment rack 209, the thicker the ice layer. The displacement sensor detects the movement amount of the adjustment rack 209, and the central control adjusts the speed of the fan 411 according to the movement amount of the adjustment rack 209. The greater the movement amount of the adjustment rack 209, that is, the thicker the ice layer, the faster the speed of the fan 411, and the more hot air flow is blown out by the air nozzle 412, so that the ice layer melts quickly. As the de-icing module moves, the moving rack 407 is driven to move through the power rod 202 and the telescopic sleeve 408, and the moving rack 407 drives the rotating gear 405 to rotate, and the rotating gear 405 drives the corresponding driving rod 406 to rotate and allows the insulation sleeve 404 to rotate half a circle, so that the insulation sleeve 404 separates the contact groove 402 and the cylindrical groove 403, that is, the heat will not flow to the area where the ice has melted, and the heat will flow to the unmelted area through the heat storage pipe 409, thereby greatly reducing energy consumption.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
