Abstract
Description
Technical Field
[0001] This invention relates to the field of inflatable membrane equipment technology, and in particular to a method and system for preventing snow accumulation on the surface of an inflatable membrane. Background Technology
[0002] Inflatable membrane structures are flexible structures that rely on pressurized fans to supply air to the enclosed space, creating a pressure difference between the inside and outside of the membrane to support the main body. They have rapidly developed in my country due to their advantages such as large space area, no beams or columns, simple and quick construction, and low cost. Increasing pressure effectively improves the rigidity of inflatable membrane structures, giving them a certain degree of wind and snow resistance. However, in recent years, severe weather conditions, including widespread blizzards and freezing rain in northern China, have significantly impacted inflatable membrane structures. As snow accumulation on the membrane increases, there is a risk of the membrane material denting or even collapsing.
[0003] Currently, research on snow protection solutions for inflatable membrane structures is relatively limited, with most studies focusing on structural design and material properties. In recent years, with the rapid development of inflatable membrane structures across various industries, the problem of snow impact damage to these structures has become particularly serious, making research on snow protection solutions for inflatable membrane structures an urgent priority. Summary of the Invention
[0004] In view of this, the present invention proposes a method and system for preventing snow accumulation on an inflatable membrane surface, the specific solution of which is as follows:
[0005] Firstly, a method for preventing snow accumulation on an inflatable membrane surface is proposed, which is applied to an inflatable membrane surface snow prevention system. The system includes a water supply main pipe, a water pump and at least one water supply branch pipe installed on the water supply main pipe. The water supply branch pipe is laid along the surface of the inflatable membrane, and at least a control valve is installed on at least part of the water supply branch pipe. At least one cleaning structure is installed on the water supply branch pipe. The surface of the inflatable membrane includes multiple snow accumulation areas, and each snow accumulation area corresponds to at least one cleaning structure.
[0006] Methods to prevent snow accumulation include:
[0007] Acquire the snow thickness in each snow-covered area on the surface of the inflatable membrane and the current environmental data at the location of the inflatable membrane;
[0008] When the snow depth in a snow-covered area reaches a preset value, a snow-proofing operation is performed on the snow-covered area. The snow-proofing operation includes:
[0009] The water supply pressure and timing are determined based on snow depth and current environmental data.
[0010] Turn on the water pump and the control valve for the corresponding snow accumulation area. The water pump delivers the cleaning water flow with the corresponding water supply pressure to the water supply main pipe, and the water supply main pipe delivers the cleaning water flow to the water supply branch pipe and the cleaning structure.
[0011] The cleaning structure sprays cleaning water into its corresponding snow-covered area within the water supply time range to clear the snow in the snow-covered area;
[0012] Once the snow in the snow-covered area has been cleared, the snow prevention operation is complete.
[0013] In practical applications, there can be multiple water supply mains, and control valves can also be installed on the water supply mains. In one specific embodiment, the control valve can be an electric control valve, and the user can adjust the operation of the corresponding water supply branch pipes on different snow accumulation areas on the aerated membrane surface by opening or closing the control valves on each water supply main or branch pipe in batches or quickly.
[0014] In some specific embodiments, the method further includes: after the snow removal operation in all snow-covered areas is completed, turning off the water pump and draining the residual water in the water supply main and branch pipes.
[0015] In some specific embodiments, a drain valve is also provided on the water supply main and / or water supply branch pipes; the process of draining residual water in the water supply main and water supply branch pipes includes:
[0016] Compressed air is injected into the water supply main pipe. The compressed air passes through the water supply branch pipe and is sprayed out by the cleaning structure to remove some of the residual water in the water supply main pipe and water supply branch pipe.
[0017] Open the drain valve to drain the remaining water in the main water supply pipe and / or branch water supply pipe.
[0018] In practical applications, after snow removal from the inflatable membrane surface is completed and the water pump is turned off, residual cleaning water may still remain in the main and branch water supply pipes. In cold weather, this residual cleaning water may freeze, causing blockages and potentially further freezing and damage to the pipes. To address this, compressed air is injected into the main water supply pipe to effectively expel any remaining water through the cleaning mechanism, ensuring unobstructed flow. Simultaneously, the drain valve and the drain outlet on the main and / or branch water supply pipes it controls can be positioned at the lowest possible point on the main and / or branch water supply pipes to ensure that any remaining residual water in the main water supply pipe is completely drained by gravity.
[0019] In some specific embodiments, an adjusting valve is also provided between the cleaning structure and the water supply branch pipe, and the method further includes:
[0020] Get the current snow thickness of the snow-covered area corresponding to the clearing structure;
[0021] If the current snow thickness is not greater than the preset threshold, determine the amount of water and / or the flow rate of the cleaning water stream based on the current snow thickness and environmental data.
[0022] The control valve enables the cleaning structure to perform spraying operations based on a determined water volume and / or water flow rate.
[0023] If the current snow thickness is greater than the preset threshold, the amount of water and / or the flow rate of the cleaning water will be determined based on the current snow thickness and environmental data.
[0024] The control adjustment valve enables the cleaning structure to spray based on a determined water volume and / or water flow rate, and after a preset time interval, performs the operation of "obtaining the current snow thickness of the snow accumulation area corresponding to the cleaning structure".
[0025] In some specific embodiments, before delivering the cleaning water stream to the water supply main via a water pump, the method further includes:
[0026] After the water pump draws cleaning water from an external water source, the cleaning water is filtered. In practical applications, this can be done using a filtration device. Filtration reduces impurities in the cleaning water, prevents pipe blockage, and extends the service life of the pipes.
[0027] In some specific embodiments, the system further includes a de-icing agent adding device connected to the water supply main; and before the water supply main delivers the cleaning water flow to the water supply branch pipe and the cleaning structure, it further includes:
[0028] The difficulty of this snow removal operation will be assessed based on current environmental data and the current snow thickness in each snow-covered area.
[0029] When the difficulty of execution reaches the preset value, de-icing agent is added to the cleaning water stream through the de-icing agent adding device.
[0030] In some specific embodiments, a heating device connected to the water supply main is also included; before the water supply main delivers the cleaning water flow to the water supply branch pipe and the cleaning structure, the following is also included:
[0031] The water supply temperature is determined based on snow depth and current environmental data.
[0032] The temperature of the cleaning water is heated to the corresponding supply water temperature by a heating device.
[0033] In some specific embodiments, the water supply pressure and water supply time are determined based on the snow thickness and current environmental data, including: importing the snow thickness and current environmental data into the currently trained prediction model to obtain the water supply pressure and water supply time;
[0034] The method also includes: after completing the snow removal operation, acquiring environmental data, snow thickness and operation data in each snow area, including water supply pressure, water supply time and snow removal effect; and storing the acquired environmental data, snow thickness and operation data as historical data.
[0035] The method also includes:
[0036] The latest prediction model is trained periodically based on historical data.
[0037] In practical applications, prediction models can include deep learning models, time series models, machine learning models, etc. By analyzing or training historical data and learning various meteorological factors related to snow thickness, predictions of snow thickness can be made, which can further enable the simulation and data prediction of the snow removal process.
[0038] By training a predictive model using historical data, users can quickly obtain the necessary values for snow removal operations after acquiring snow depth and current environmental data. Since these values are derived from training the predictive model on a large amount of historical data, they can effectively simulate actual conditions and achieve snow removal results similar to those observed in historical data. Users can directly apply the values provided by the predictive model or use them as a reference to determine the water pressure and timing for subsequent snow removal operations. After multiple snow removal operations, the predictive model can obtain more effective data for training, and its output data will gradually become more accurate, maximizing snow removal efficiency, achieving better snow removal results, and effectively conserving water and electricity resources without waste.
[0039] Secondly, an inflatable membrane surface snow prevention system is proposed, which is applicable to any of the snow prevention methods for inflatable membrane surfaces as described in the aforementioned technical solutions, including: a monitoring system, a water supply system, and a cleaning system;
[0040] The monitoring system includes a snow thickness sensor and a temperature sensor. The snow thickness sensor is used to obtain the snow thickness in various snow-covered areas on the surface of the inflatable membrane; the temperature sensor is used to obtain the current environmental data at the location of the inflatable membrane. In practical applications, the snow thickness sensor and the temperature sensor can be connected to the surface of the inflatable membrane or placed close to it.
[0041] The water supply system includes a water supply main pipe, on which a water pump is installed; the water pump is used to deliver a stream of cleaning water to the water supply main pipe at the corresponding water supply pressure;
[0042] The cleaning system includes at least one water supply branch pipe and a cleaning structure. The water supply branch pipe is connected to the water supply main pipe and is laid along the surface of the air-supported membrane. At least a portion of the water supply branch pipe is equipped with a control valve. The surface of the air-supported membrane includes multiple snow accumulation areas. Each snow accumulation area corresponds to at least one cleaning structure. The cleaning structure is used to spray cleaning water into its corresponding snow accumulation area within the water supply time range.
[0043] In practical applications, the cleaning structure includes a cleaning nozzle or water outlet channel. It should be noted that, as long as it can achieve the goal of spraying water onto the surface of the aerated membrane under pressure from a water pump to clear snow accumulation on the membrane surface, the cleaning structure can be configured with various different appearances and specific structures. For example, the cleaning nozzle can include a flat-nozzle nozzle and / or a herringbone nozzle to spray a fan-shaped water stream to clear snow from the aerated membrane surface.
[0044] In some specific embodiments, the water supply system further includes a system controller, which is communicatively connected to the monitoring system, water pumps, and control valves. The system controller is used to acquire data from the monitoring system and to perform batch or individual control of the operation of the water pumps and control valves.
[0045] In practical applications, the system controller can be used to calculate and determine the water supply pressure and water supply time, or it can be used to train the prediction model and process the input and output of data.
[0046] In some specific embodiments, the water supply system further includes a drain valve, a heating device, and an air compressor, with the heating device and the air compressor both installed on the water supply main pipe; the drain valve is installed on the water supply main pipe and / or the water supply branch pipe.
[0047] The heating device is used to heat the temperature of the cleaning water flow to the corresponding water supply temperature after determining the water supply temperature based on the snow thickness and current environmental data; the air compressor is used to pressurize compressed air into the water supply main pipe, and the compressed air passes through the water supply branch pipe and is ejected by the cleaning structure to discharge a portion of the residual water in the water supply main pipe and / or water supply branch pipe; the drain valve is used to discharge another portion of the residual water in the water supply main pipe and / or water supply branch pipe when it is opened.
[0048] In some specific embodiments, it also includes a fixing buckle and an anti-slip device; the surface of the inflatable membrane is covered with a fixing cable net, and the water supply branch pipe and the fixing cable net are connected by the fixing buckle to be fixedly connected to the surface of the inflatable membrane; the anti-slip device is sleeved on the water supply branch pipe near the connection between the water supply branch pipe and the fixing cable net, and is used to engage with the fixing buckle to prevent the water supply branch pipe from sliding relative to the surface of the inflatable membrane.
[0049] In some specific embodiments, the water supply system also includes a de-icing agent adding device, which is connected to the water supply main pipe and / or water supply branch pipe for adding de-icing agent to the cleaning water flow.
[0050] In some specific embodiments, the water supply system also includes a filtration device connected to one end of the water supply main pipe connected to an external water source, used to filter the clean water flow obtained by the water pump.
[0051] In some specific embodiments, the main water supply pipe is a rigid pipe, and the branch water supply pipes are flexible pipes. In one specific embodiment, the bottom of the inflatable membrane is connected to the ground via a retaining wall, the main water supply pipe is installed along the retaining wall, one end of the branch water supply pipe is connected to the main water supply pipe, and the pipe body and the other end are laid on the surface of the inflatable membrane. Since the surface of the inflatable membrane is an arc-shaped surface, the flexible branch water supply pipe can fit well with the surface of the inflatable membrane. In one specific embodiment, the branch water supply pipe has a slope in the direction against the water flow, and this slope is greater than or equal to 0.1%. This allows the water flow to flow in the direction of gravity in the pipe, which can effectively prevent the water flow from stagnating in the pipe and causing water accumulation.
[0052] Beneficial Effects: This application proposes a method and system for preventing snow accumulation on an inflatable membrane surface. When the snow thickness in a snow-covered area reaches a preset value, a snow-clearing operation is performed on the snow-covered area. This allows the cleaning structure to spray water onto the corresponding snow-covered area within a specified water supply time, thereby clearing the snow. This enables snow clearing using an inflatable membrane structure without the need for personnel, eliminating the high-altitude risks associated with manual snow removal during snowfall, significantly improving safety performance, and reducing unnecessary labor costs.

[0066] Example 1
[0067] This embodiment discloses a method for preventing snow accumulation on an inflatable membrane surface, the specific scheme of which is as follows:
[0068] Firstly, a method for preventing snow accumulation on the surface of an inflatable membrane is proposed, which is applied to an inflatable membrane 6 snow accumulation prevention system. The system includes a water supply main pipe 12, on which a water pump 11 and at least one water supply branch pipe 21 are installed. The water supply branch pipe 21 is laid along the surface of the inflatable membrane 6, and at least a control valve 17 is installed on at least part of the water supply branch pipe 21. At least one cleaning structure 22 is installed on the water supply branch pipe 21. The surface of the inflatable membrane 6 includes multiple snow accumulation areas, and each snow accumulation area corresponds to at least one cleaning structure 22.
[0069] like Figure 1 As shown, snow prevention methods include:
[0070] S100: Obtain the snow thickness in each snow-covered area on the surface of the inflatable membrane 6 and the current environmental data at the location of the inflatable membrane 6;
[0071] S200. When the snow thickness in the snow-covered area reaches a preset value, a snow-proofing operation is performed on the snow-covered area. The snow-proofing operation includes:
[0072] S210. Determine the water supply pressure and water supply time based on snow thickness and current environmental data;
[0073] S220, turn on the water pump 11 and the control valve 17 corresponding to the snow accumulation area, and deliver the cleaning water flow with the corresponding water supply pressure to the water supply main pipe 12 through the water pump 11. The water supply main pipe 12 delivers the cleaning water flow to the water supply branch pipe 21 and the cleaning structure 22.
[0074] S230, the cleaning structure 22 sprays cleaning water into the corresponding snow accumulation area within the water supply time range to clean the snow accumulation in the snow accumulation area;
[0075] S240. Once the snow in the snow-covered area has been cleared, the snow prevention operation is completed.
[0076] In practical applications, there can be multiple water supply mains 12, and control valves 17 can also be installed on the water supply mains 12. In one specific embodiment, the control valve 17 can be an electric control valve 17. Users can adjust the operation of the corresponding water supply branch pipes 21 on different snow accumulation areas on the surface of the air-filled membrane 6 by opening or closing the control valves 17 on each water supply main 12 or water supply branch pipe 21 in batches or quickly.
[0077] In practical applications, the cleaning structure 22 includes a cleaning nozzle or water outlet channel. It should be noted that, as long as it can achieve the goal of spraying a cleaning water stream onto the surface of the aerated membrane 6 under the pressure of the water pump 11 to clean the snow accumulation on the surface of the aerated membrane 6, the cleaning structure 22 can be configured with various different appearances and specific structures. For example, the cleaning nozzle may include a flat nozzle and / or a herringbone nozzle to spray a fan-shaped water stream to clean the snow accumulation on the surface of the aerated membrane 6, thus completing the snow-proofing operation.
[0078] In some specific embodiments, such as Figure 2 As shown, it also includes:
[0079] S300. After the snow removal operation in all snow-covered areas is completed, turn off the water pump 11 and drain the residual water in the water supply main pipe 12 and water supply branch pipe 21.
[0080] In some specific embodiments, a drain valve 18 is also provided on the water supply main pipe 12 and / or water supply branch pipe 21; step S300 is specifically as follows: Figure 3 As shown, it includes:
[0081] S310. Compressed air is injected into the water supply main pipe 12. The compressed air passes through the water supply branch pipe 21 and is sprayed out by the cleaning structure 22 to discharge some of the residual water in the water supply main pipe 12 and the water supply branch pipe 21.
[0082] S320. Open the drain valve 18 to drain the remaining water in the water supply main pipe 12 and / or water supply branch pipe 21.
[0083] In practical applications, after the snow removal from the surface of the inflatable membrane 6 is completed and the water pump 11 is turned off, residual cleaning water may still remain in the water supply main pipe 12 and water supply branch pipe 21. In cold weather, this residual cleaning water may freeze, causing blockages in the pipes. The accumulated water may further freeze and damage the pipes. In practical applications, by injecting compressed air into the water supply main pipe 12, the residual water in the water supply main pipe 12 and water supply branch pipe 21 can be effectively blown out through the cleaning structure 22, ensuring the unobstructed flow of the water supply main pipe 12 and water supply branch pipe 21. Simultaneously, the drain valve 18 and the drain outlet on the water supply main pipe 12 controlled by the drain valve 18 can be positioned at the lowest point on the water supply main pipe 12 to ensure that any remaining residual water in the water supply main pipe 12 can be completely drained by the drain valve 18 under the influence of gravity.
[0084] In some specific embodiments, an adjusting valve 171 is also provided between the cleaning structure 22 and the water supply branch pipe 21, such as... Figure 4 As shown, the method also includes:
[0085] S510, Obtain the current snow thickness of the snow-covered area corresponding to the clearing structure 22;
[0086] S511. If the current snow thickness is not greater than the preset threshold, determine the amount of water and / or the flow rate of the cleaning water flow based on the current snow thickness and environmental data.
[0087] S512, Control adjustment valve 171 causes cleaning structure 22 to perform spraying operation based on a determined water volume and / or water flow rate;
[0088] S521. If the current snow thickness is greater than the preset threshold, the amount of water and / or the flow rate of the cleaning water stream are determined based on the current snow thickness and environmental data.
[0089] S522, control adjustment valve 171 to make cleaning structure 22 spray based on a determined water volume and / or water flow rate, and after a preset time interval, perform the operation of "obtaining the current snow thickness of the snow accumulation area corresponding to cleaning structure 22".
[0090] By setting an adjustment valve 171 for the snow-clearing structure 22 and periodically detecting the current snow thickness, when the current snow thickness exceeds a threshold, the snow thickness can be periodically re-detected and updated during the operation of the snow-clearing structure 22. This allows for flexible adjustment of the water consumption and flow rate of the snow-clearing structure 22, ensuring that the snow-clearing efficiency of each snow-covered area remains at a high level and reducing water waste. In practical applications, the current snow thickness in the snow-covered area corresponding to the snow-clearing structure 22 can be detected using methods such as infrared detection.
[0091] In some specific embodiments, before step 220, when the cleaning water is pumped to the water supply main by pump 11, such as Figure 3 As shown, it also includes:
[0092] S410. After the water pump 11 obtains cleaning water from an external water source, the cleaning water is filtered.
[0093] In practical applications, the cleaning water flow can be filtered through the filter device 19. Filtration can reduce impurities in the cleaning water flow, prevent pipe blockage, and extend the service life of the pipe.
[0094] In some specific embodiments, a de-icing agent adding device 13 connected to the water supply main 12 is also included; before the water supply main 12 delivers the cleaning water flow to the water supply branch 21 and the cleaning structure 22, the following is also included:
[0095] S421. Determine the difficulty of this snow removal operation based on the current environmental data and the current snow thickness in each snow-covered area;
[0096] S422. When the execution difficulty reaches the preset value, snow melting agent is added to the cleaning water flow through the snow melting agent adding device 13.
[0097] In practical applications, the de-icing agent adding device 13 can be connected to the water supply main pipe 12 and / or the water supply branch pipe 21. In one specific embodiment, it also includes a system controller 16. The drain valve 18, the air compressor 14, and the de-icing agent adding device 13 can all be communicatively connected to the system controller 16 and operate under the control of the system controller 16, allowing the user to remotely manage each device in the system. At the same time, the difficulty of snow removal operations can be visually observed manually, and de-icing agent can be added to the cleaning water flow in real time through the system controller 16 or manually.
[0098] In some specific embodiments, step S210 includes: S211, importing snow thickness and current environmental data into the currently trained prediction model to obtain water supply pressure and water supply time;
[0099] The method also includes: after completing the snow removal operation, acquiring environmental data, snow thickness and operation data in each snow area, including water supply pressure, water supply time and snow removal effect; and storing the acquired environmental data, snow thickness and operation data as historical data.
[0100] The method also includes periodically training the latest prediction model based on historical data.
[0101] In practical applications, prediction models can include deep learning models, time series models, machine learning models, etc. By analyzing or training historical data and learning various meteorological factors related to snow thickness, predictions of snow thickness can be made, which in turn enables the simulation and data prediction of the snow removal process.
[0102] In one specific embodiment, when a heating device 15 is installed on the water supply main, the water supply temperature can also be used as one of the operational data during the training of the prediction model, and further stored as historical data, so that the prediction model can also obtain the water supply temperature data after importing the snow thickness and current environmental data.
[0103] By training a prediction model using historical data, users can quickly obtain the necessary values for snow removal operations after acquiring snow depth and current environmental data. Furthermore, since these values are derived from training the prediction model on a large amount of historical data, they can effectively simulate actual conditions and achieve snow removal results similar to those observed in historical data. Users can directly apply the values provided by the prediction model or use them as a reference to determine the water pressure, temperature, and timing for subsequent snow removal operations. After multiple snow removal operations, the prediction model can obtain more effective data for training, and its output data will gradually become more accurate, leading to better snow removal results.
[0104] This embodiment proposes a method for preventing snow accumulation on an inflatable membrane surface. When the snow thickness in a snow-covered area reaches a preset value, a snow-clearing operation is performed. This involves a cleaning structure spraying water onto the corresponding snow-covered area within a specified water supply timeframe to clear the snow. This allows the inflatable membrane structure to clear snow without human intervention, eliminating the risks associated with manual snow removal at heights during snowfall, significantly improving safety, and reducing unnecessary labor costs.
[0105] Example 2
[0106] This embodiment discloses an inflatable membrane surface snow-proofing system, which can be used to implement any of the above-mentioned inflatable membrane surface snow-proofing methods, including:
[0107] An inflatable membrane surface snow prevention system is proposed, which is applicable to any of the snow prevention methods for inflatable membrane surfaces as described in the aforementioned technical solutions, including: a monitoring system 3, a water supply system 1, and a cleaning system 2;
[0108] The monitoring system 3 includes a snow thickness sensor 31 and a temperature sensor 32. The snow thickness sensor 31 is used to acquire the snow thickness in various snow-covered areas on the surface of the inflatable membrane 6; the temperature sensor 32 is used to acquire current environmental data at the location of the inflatable membrane 6. In practical applications, the snow thickness sensor 31 and the temperature sensor 32 can be connected to the surface of the inflatable membrane 6 or positioned close to the inflatable membrane 6. In a specific embodiment, such as... Figure 6 As shown, the monitoring system 3 is positioned close to the inflatable membrane 6.
[0109] The water supply system 1 includes a water supply main pipe 12, on which a water pump 11 is installed; the water pump 11 is used to deliver cleaning water flow corresponding to the water supply pressure to the water supply main pipe 12.
[0110] The cleaning system 2 includes at least one water supply branch pipe 21 and a cleaning structure 22. The water supply branch pipe 21 is connected to the water supply main pipe 12 and is laid along the surface of the air-supported membrane 6. At least a portion of the water supply branch pipe 21 is equipped with a control valve 17. The surface of the air-supported membrane 6 includes multiple snow accumulation areas. Each snow accumulation area corresponds to at least one cleaning structure 22. The cleaning structure 22 is used to spray cleaning water into its corresponding snow accumulation area within the water supply time range.
[0111] In one specific embodiment, some of the cleaning structures 22 may be uniformly arranged along the water supply branch pipe 21. In actual application, the cleaning water flow is pressurized by the water pump 11, which causes the cleaning structures 22 to spray water to clean the surface of the air-filled membrane 6.
[0112] In practical applications, the cleaning structure 22 includes a cleaning nozzle or water outlet channel. It should be noted that, as long as it can achieve the goal of spraying a cleaning water stream onto the surface of the aerated membrane 6 under the pressure of the water pump 11 to clean the snow accumulation on the surface of the aerated membrane 5, the cleaning structure 22 can be configured with various different appearances and specific structures. For example, the cleaning nozzle may include a flat nozzle and / or a herringbone nozzle to spray a fan-shaped water stream to clean the snow accumulation on the surface of the aerated membrane 6.
[0113] It should be noted that this embodiment does not specifically limit the direction of the cleaning water sprayed by the cleaning structure 22. As long as the snow accumulation on the surface of the inflatable membrane 6 can be cleared, the user can adjust the direction of the cleaning water sprayed by the cleaning structure 22 according to actual needs, such as... Figure 6As shown, the cleaning structure 22 is located on top of the inflatable membrane 6 and sprays cleaning water along a preset first direction, wherein the preset first direction is approximately parallel to the ground.
[0114] In some specific embodiments, the water supply system 1 further includes a system controller 16, which is communicatively connected to the monitoring system 3, the water pump 11, the heating device 15, and the control valve 17. The system controller 16 is used to acquire data from the monitoring system 3 and to perform batch or individual control of the operation of the water pump 11, the heating device 15, and the control valve 17.
[0115] In some specific embodiments, the water supply system also includes a drain valve 18, a heating device and an air compressor, both of which are connected to the water supply main pipe; the drain valve 18 is installed on the water supply main pipe and / or the water supply branch pipe.
[0116] The heating device is used to heat the cleaning water flow to the corresponding water supply temperature after determining the supply water temperature based on the snow thickness and current environmental data. By setting the heating device 15, the cleaning water flow can be heated to clean the snow on the surface of the air-supported membrane 6 with hot water, melting the snow in contact with the surface of the air-supported membrane 6, and melting some or all of the snow on the surface of the air-supported membrane 6. Under the action of gravity and water flow, the snow slides down the surface of the air-supported membrane 6, which can effectively accelerate the melting and sliding speed of the snow and improve the snow cleaning efficiency.
[0117] The air compressor 14 is used to pressurize compressed air into the water supply main pipe 12. The compressed air passes through the water supply branch pipe 21 and is sprayed out by the cleaning structure 22 to discharge a portion of the residual water in the water supply main pipe 12 and the water supply branch pipe 21. The drain valve 18 is used to discharge another portion of the residual water in the water supply main pipe 12 and / or the water supply branch pipe 21 when it is opened.
[0118] In some specific embodiments, the water supply system 1 further includes a de-icing agent adding device 13, which is connected to the water supply main pipe 12 and / or the water supply branch pipe 21, and is used to add de-icing agent to the cleaning water flow.
[0119] In practical applications, such as Figure 9 As shown, the drain valve 18, the air compressor 14, and the snow melting agent adding device 13 can all be connected to the system controller 16 and operate under the control of the system controller 16, allowing users to remotely manage each device in the system, which can effectively improve the automation and intelligence of the snow prevention system.
[0120] In some specific embodiments, such as Figure 7 As shown, it also includes a fixing buckle 41 and an anti-slip device 42; the surface of the inflatable membrane 6 is covered with a fixing cable net 4, such as Figure 7As shown, the water supply branch pipe 21 and the fixing cable net 4 are connected by the fixing buckle 41 to be fixedly connected to the surface of the air-filled membrane 6; the anti-slip device 42 is sleeved on the water supply branch pipe 21 near the connection between the water supply branch pipe 21 and the fixing cable net 4, and is used to engage with the fixing buckle 41 to prevent the water supply branch pipe 21 from sliding relative to the surface of the air-filled membrane 6.
[0121] In some specific embodiments, the water supply system 1 further includes a filter device 19, which is connected to one end of the water supply main pipe 12 that is connected to an external water source, and is used to filter the cleaning water flow obtained by the water pump 11.
[0122] In some specific embodiments, the water supply main pipe 12 is a rigid pipe, and the water supply branch pipe 21 is a flexible pipe. In one specific embodiment, such as Figure 7 As shown, the bottom of the inflatable membrane 6 is connected to the ground via a retaining wall 62. The water supply main pipe 12 is installed along the retaining wall 62. One end of the water supply branch pipe 21 is connected to the water supply main pipe 12, while the pipe body and the other end are laid on the surface of the inflatable membrane 6. Since the surface of the inflatable membrane 6 is an arc-shaped surface, the water supply branch pipe 21, being a flexible pipe, can fit well with the surface of the inflatable membrane 6. In a specific embodiment, the water supply branch pipe 21 has a slope in the direction against the water flow, which is greater than or equal to 0.1%. This allows the water flow to proceed along the direction of gravity in the pipe, effectively preventing water from stagnating and accumulating inside the pipe.
[0123] In one specific embodiment, some of the water supply branch pipes 21 are laid at the top of the surface of the inflatable membrane 6 in a direction approximately parallel to the ground, such as... Figure 5 and Figure 7 As shown, some water supply branch pipes 21 are arranged along the centerline 61 of the inflatable membrane 6 in the top view direction and extend along a preset first direction, while some water supply branch pipes 21 extend along a preset second direction. The preset first direction is approximately parallel to the horizontal plane and has a small slope; the preset second direction is approximately perpendicular to the horizontal plane and has a large slope. By setting a slope for the water supply branch pipes 21, water accumulation in the water supply branch pipes 21 can be effectively prevented. The preset first direction is as follows... Figure 5 As shown in the middle direction A, the preset second direction is as follows: Figure 5 As shown in the middle direction B.
[0124] This embodiment provides an inflatable membrane surface snow-proofing system, which can be used to implement any of the inflatable membrane surface snow-proofing methods in Embodiment 1. When the snow thickness in the snow-covered area reaches a preset value, a snow-proofing operation is performed on the snow-covered area. The cleaning structure sprays cleaning water into the corresponding snow-covered area within the water supply time range to clear the snow. This allows the inflatable membrane structure to clear snow without human intervention, eliminating the high-altitude risks associated with manual snow removal during snowfall, greatly improving safety performance, and reducing unnecessary labor costs. Furthermore, by setting up a monitoring system, system controller, and control valves, the snow-clearing process on the inflatable membrane surface can be automated. The melting speed of snow on the inflatable membrane surface can be further accelerated by setting up heating devices and de-icing agent addition devices. The installation of an air compressor effectively solves the problem of residual water in the water supply main and branch pipes, protecting the inflatable membrane and the device itself, and reducing the threat posed by severe weather such as wind and snow to the inflatable membrane.
