Description

Technical Field

[0001] The utility model relates to the field of air membranes, in particular to a device for preventing snow accumulation on the surface of an inflatable membrane. Background Art

[0002] The inflatable membrane structure is a flexible structure. It mainly relies on a pressurized fan to supply air and pressurize the enclosed space, so that a pressure difference is formed inside and outside the membrane, thereby achieving a structure that supports the main body of the air membrane. It has developed rapidly due to its advantages such as large space area, no beams and columns, simple and quick construction, and low cost. The inflatable membrane structure can effectively increase its stiffness when the pressure is increased, so the inflatable membrane structure has certain wind and snow resistance functions.

[0003] Existing inflatable membrane structures are very susceptible to severe weather conditions during winter windy and snowy weather. As the thickness of snow on the membrane surface increases, there is a risk that the membrane material of the inflatable membrane structure will sag or even collapse. Currently, most research focuses on the structural design and material properties of inflatable membranes, while there is relatively little research on anti-snow accumulation solutions for inflatable membrane structures. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides an inflatable membrane surface anti-snow accumulation device to solve at least one of the above-mentioned technical problems.

[0005] An inflatable membrane surface snow accumulation prevention device includes a water supply system and a cleaning system. The water supply system includes a water pump and a water supply main pipe; the water pump is arranged at one end of the water supply main pipe connected to an external water source.

[0006] Among them, the cleaning system includes a water supply branch pipe; one or more water supply branches are connected to the other end of each water supply main pipe, the water supply branches are laid on the surface of the inflatable membrane, and each water supply branch pipe is provided with one or more water outlet structures.

[0007] In actual application, the bottom of the inflatable membrane is connected to the ground through a retaining wall. The water supply main pipe is a rigid pipe and can be set along the retaining wall; the water supply branch pipe is a flexible pipe and can be set along the curved surface of the inflatable membrane.

[0008] In a specific embodiment, the water outlet structure includes a cleaning nozzle and / or a water outlet channel.

[0009] In a specific embodiment, the cleaning nozzles and / or water outlet channels can be evenly arranged along the water supply branch pipe, and each cleaning nozzle and / or water outlet channel corresponds to a different area on the surface of the inflatable membrane. It should be noted that as long as the snow on the surface of the inflatable membrane can be cleaned, the water outlet structure can have a variety of shapes and structures. For example, the cleaning nozzle can include a flat nozzle and / or a fishbone nozzle that can spray a fan-shaped water flow. In actual application, the cleaning water flow is pressurized by a water pump, so that the cleaning nozzle can spray a fan-shaped water flow to clean the surface of the inflatable membrane.

[0010] In some specific embodiments, a monitoring system is further included, and the monitoring system is connected to the surface of the inflatable membrane or is arranged near the surface of the inflatable membrane.

[0011] In some specific embodiments, the monitoring system includes at least one snow thickness sensor and / or temperature sensor. The snow thickness sensor is positioned near the inflatable membrane to detect the thickness of snow in the external environment; alternatively, the snow thickness sensor is positioned on the surface of the inflatable membrane to detect the actual thickness of snow accumulated on the surface of the inflatable membrane. In actual applications, there is a certain quantitative relationship between the thickness of snow accumulated in the external environment, such as the ground or other building surfaces, and the thickness of snow accumulated on the surface of the inflatable membrane. Therefore, the thickness of snow accumulated on the surface of the inflatable membrane can be further inferred based on the snow thickness in the external environment.

[0012] The temperature sensor is arranged close to the inflatable membrane to detect the external environment temperature; or the temperature sensor is located on the surface of the inflatable membrane to directly detect the temperature of the inflatable membrane surface.

[0013] In some specific embodiments, the water supply system further includes a deicing agent addition device connected to the water supply main pipe and / or the water supply branch pipe. During the process of clearing snow from the surface of the inflatable membrane, deicing agent is added to the water supply main pipe and / or the water supply branch pipe via the deicing agent addition device, so that the deicing agent can be dissolved into the cleaning water during the cleaning process, further improving the snow cleaning efficiency.

[0014] In some specific embodiments, the water supply system further includes an air compressor connected to the water supply main pipe for delivering compressed air into the water supply main pipe. In actual applications, when the snow on the surface of the inflatable membrane is cleared and the water pump is turned off, undischarged cleaning water may still remain in the water supply main pipe and the water supply branch pipe. In cold weather, the cleaning water remaining in the water supply main pipe and the water supply branch pipe may freeze, which will block the pipe. The accumulated water may further freeze and cause the pipe to expand and crack, causing damage to the pipe. By using an air compressor to deliver compressed air into the water supply main pipe, the compressed air passes from the water supply main pipe through the water supply branch pipe and is then sprayed out by the water outlet structure, and the water stains remaining in the pipe can be sprayed out at the same time, thereby clearing the accumulated water in the water supply main pipe and the water supply branch pipe.

[0015] In some embodiments, the water supply system further includes a drain valve disposed on the end of the water supply main pipe connected to the external water source and / or on the water supply branch pipe. In a specific application, after snow has been cleared from the surface of the inflatable membrane, the drain valve can be opened manually or via a signal control to drain any remaining water from the water supply main pipe and the water supply branch pipe.

[0016] In one embodiment, the water supply system may further include an adjustment valve disposed between the water outlet structure and the water supply branch pipe. This adjustment valve can individually adjust the water flow rate of the corresponding water outlet structure. In practical applications, the adjustment valve can be communicatively connected to the system controller, allowing the user to remotely adjust the water flow rate of each water outlet structure through the system controller, making the entire snow clearing process more flexible and targeted.

[0017] In actual applications, the external water source can be a pool or a mobile water supply vehicle. In a specific embodiment, the mobile water supply vehicle can have a heating function, which can heat the cleaning water to be transported to the water supply main to improve the efficiency of clearing snow.

[0018] In some specific embodiments, the water main and branch pipes have a slope against the water flow. In practical applications, the slope of some or all of the branch pipes against the water flow is greater than or equal to 0.1%. By providing the branch pipes with a slope against the water flow, water can flow in the pipes in the direction of gravity, preventing stagnation and accumulation of water in the pipes.

[0019] In some specific embodiments, the water supply system further includes a water heating device connected to the end of the water supply main connected to the external water source and communicatively connected to the monitoring system. The water heating device heats the cleaning water, enabling the use of hot water to clean snow from the surface of the inflatable membrane, effectively accelerating the melting and sliding of snow and improving cleaning efficiency.

[0020] In some specific embodiments, the water supply system further includes a system controller and control valves, with all control valves communicatively connected to the system controller. Control valves may be installed on some or all of the water supply mains, and / or on some or all of the water supply branch pipes. In practical applications, when the surface area of ​​the inflatable membrane is large, varying snow thicknesses may occur on different areas of the membrane surface. Users can operate the system controller to open or close the control valves on each water supply main or branch pipe in batches or rapidly.

[0021] In an actual application process, the system controller can also be connected to the monitoring system and the water supply heating device. After the temperature sensor in the monitoring system detects the temperature of the external environment or the temperature of the inflatable membrane surface from the outside, this data is sent to the system controller. The system controller further calculates the target temperature of the cleaning water required to be heated by the water supply heating device based on this data and sends it to the water supply heating device. The water supply heating device heats the cleaning water. When the cleaning water reaches the target temperature, the water pump further transports the cleaning water from the water supply main pipe to the water supply branch pipe, forming a jet of water at the water outlet structure to clear the snow on the surface of the inflatable membrane.

[0022] In a specific application process, the surface of the inflatable membrane can be divided into multiple snow accumulation areas, each snow accumulation area is connected to a water supply branch pipe, and each water supply branch pipe is provided with multiple water outlet structures. The spraying range of different water outlet structures can cover different positions on the snow accumulation area, and the spraying ranges between different water outlet structures can overlap with each other.

[0023] In some specific embodiments, the water supply system further includes a filter device, through which the water supply main is connected to an external water source. By using the filter device to filter the cleaning water entering the water supply main, impurities in the cleaning water can be reduced, further reducing the risk of clogging of the pipeline and the water outlet structure.

[0024] Some specific embodiments also include a fastener and an anti-slip device. The water supply branch pipe and the external cable net on the surface of the inflatable membrane are fixedly connected to the surface of the inflatable membrane via the fastener; the anti-slip device is installed on the water supply branch pipe near the connection between the water supply branch pipe and the external cable net. In one application, the external cable net is installed on the surface of the inflatable membrane, and the fastener is a U-shaped fastener. Through the U-shaped fastener, the water supply branch pipe can be cross-engaged with the external cable net, which makes the connection between the water supply branch pipe and the inflatable membrane surface more stable.

[0025] Beneficial effects: The utility model provides an inflatable membrane surface anti-snow accumulation device. By setting up a water supply system and a cleaning system, it can realize that cleaning water flow is sprayed on the surface of the inflatable membrane through the water outlet structure, so that the accumulated snow melts and slides off the surface of the inflatable membrane, thereby realizing efficient cleaning of the snow on the surface of the inflatable membrane, which can protect the surface of the inflatable membrane, reduce the threat posed by windy and snowy weather to the inflatable membrane, and at the same time keep the surface of the inflatable membrane clean. There is no need to manually climb onto the surface of the inflatable membrane to accumulate snow, eliminating the high-altitude operation risk of manual snow cleaning on the membrane surface during snowfall, greatly improving safety performance, and reducing unnecessary labor costs.

[0041] Example

[0042] This embodiment provides an inflatable membrane surface anti-snow accumulation device that can effectively protect the surface of the inflatable membrane. The specific solution is as follows:

[0043] An inflatable membrane 6 membrane surface anti-snow accumulation device includes: a water supply system 1 and a cleaning system 2. The water supply system 1 includes a water pump 11 and a water supply main pipe 12; the water pump 11 is arranged on one end of the water supply main pipe 12 connected to an external water source.

[0044] The cleaning system 2 includes water supply branches 21. Each water supply main 12 is connected to one or more water supply branches 21 at its other end. These branches 21 are laid on the surface of the inflatable membrane 6 and are each provided with one or more water outlet structures. In practice, a retaining wall 62 is provided at the bottom of the inflatable membrane 6. The water supply main 12 is a rigid pipe and can be installed along the retaining wall 62. The water supply branches 21 are flexible pipes and can be installed along the curved surface of the inflatable membrane 6.

[0045] In a practical application, by arranging one or more water outlet structures on the water supply branch pipe 21 , the cleaning water pressurized by the water pump 11 can be sprayed out from the water outlet structure to clean the snow on the surface of the inflatable membrane 6 .

[0046] In a specific embodiment, the water outlet structure 22 includes a cleaning nozzle and / or a water outlet channel. In a specific embodiment, some of the water outlet structures 22 are evenly arranged along the water supply branch pipe 21, and each water outlet structure 22 corresponds to a different area on the surface of the inflatable membrane 6. It should be noted that as long as the snow on the surface of the inflatable membrane 6 can be cleaned, the water outlet structure 22 can have a variety of shapes and structures. For example, the cleaning nozzle can include a flat nozzle and / or a fishbone nozzle that can spray out a fan-shaped water flow. In actual application, the cleaning water flow is pressurized by the water pump 11, so that the cleaning nozzle can spray out a fan-shaped water flow to clean the surface of the inflatable membrane 6.

[0047] In some specific embodiments, a monitoring system 3 is further included, connected to or located near the surface of the inflatable membrane 6. In one specific embodiment, the monitoring system 3 includes at least one snow thickness sensor 31 and / or a temperature sensor 32. The snow thickness sensor 31 is located near the inflatable membrane 6 and is used to detect the thickness of snow in the external environment; alternatively, the snow thickness sensor 31 is located on the surface of the inflatable membrane 6 and is used to detect the actual thickness of snow on the surface of the inflatable membrane 6.

[0048] In practical applications, there is a certain quantitative relationship between the thickness of snow in the external environment, such as the ground or other building surfaces, and the thickness of snow on the surface of the inflatable membrane 6. Therefore, the thickness of snow on the surface of the inflatable membrane 6 can be further estimated by the thickness of snow in the external environment. Figure 2 , the snow thickness sensor 31 and the temperature sensor 32 may be arranged at a position close to the surface of the inflation membrane 6 .

[0049] The temperature sensor 32 is arranged close to the inflatable membrane 6 for detecting the external environment temperature; or the temperature sensor 32 is located on the surface of the inflatable membrane 6 for directly detecting the temperature of the surface of the inflatable membrane 6.

[0050] In some specific embodiments, the water supply system 1 further includes a deicing agent adding device 13; the deicing agent adding device 13 is connected to the water supply main pipe 12 and / or the water supply branch pipe 21. During the process of clearing snow from the surface of the inflatable membrane 6, deicing agent is added to the water supply main pipe 12 and / or the water supply branch pipe 21 via the deicing agent adding device 13. This allows the deicing agent to be incorporated into the cleaning water during the cleaning process, further improving the snow cleaning efficiency.

[0051] In some specific embodiments, the water supply system 1 further comprises an air compressor 14, which is connected to the water supply main pipe 12 and is used to deliver compressed air into the water supply main pipe 12. In actual applications, when the snow on the surface of the inflatable membrane 6 is cleared and the water pump 11 is turned off, there may still be residual cleaning water in the water supply main pipe 12 and the water supply branch pipe 21. In cold weather, the cleaning water remaining in the water supply main pipe 12 and the water supply branch pipe 21 may freeze, which will block the pipes. The accumulated water may further freeze and damage the pipes. By using the air compressor 14 to deliver compressed air into the water supply main pipe 12, the compressed air passes from the water supply main pipe 12 through the water supply branch pipe 21 and is then ejected from the water outlet structure 22. At the same time, the remaining water stains in the pipes can be ejected to clear the accumulated water in the water supply main pipe 12 and the water supply branch pipe 21.

[0052] In some specific embodiments, the water supply system 1 further includes a drain valve 18, which is disposed on one end of the water supply main pipe 12 connected to an external water source and / or on the water supply branch pipe 21. In a specific application, after snow is cleared from the surface of the inflatable membrane 6, the drain valve 18 can be opened manually or by signal control to drain the residual water in the water supply main pipe 12 and the water supply branch pipe 21. In a specific embodiment, the drain valve 18 and the drain port on the water supply main pipe 12 controlled by the drain valve 18 can be disposed at the lowest position on the water supply main pipe 12 to ensure that the remaining residual water in the water supply main pipe 12 can be completely drained by the drain valve 18 under the influence of gravity.

[0053] In one embodiment, the water supply system 1 may further include an adjustment valve 171 disposed between the water outlet structure 22 and the water supply branch pipe 21. This adjustment valve 171 can individually adjust the water flow rate of the corresponding water outlet structure 22. In actual use, the adjustment valve 171 can be communicatively connected to the system controller 16, allowing the user to remotely adjust the water flow rate of each water outlet structure 22 through the system controller 16, making the entire snow clearing process more flexible and targeted.

[0054] In actual applications, the external water source can be a pool or a mobile water supply vehicle. In a specific embodiment, the mobile water supply vehicle can have a heating function, which can heat the cleaning water to be transported to the water supply main 12 to improve the efficiency of clearing snow. In one embodiment, the water supply main can be connected to multiple external water sources, including multiple backup water sources, to prevent insufficient water supply.

[0055] In some specific embodiments, the water supply main pipe 12 and the water supply branch pipe 21 have a slope in the direction against the water flow. In practical applications, the slope of some or all of the water supply branch pipes 21 in the direction against the water flow is greater than or equal to 0.1%. By making the water supply main pipe 12 and the water supply branch pipe 21 have a slope in the direction against the water flow, it helps the water flow in the pipe to flow along the direction of gravity, avoiding stagnation of water flow in the pipe to cause water accumulation. Some of the water supply branch pipes 21 are laid on the top of the surface of the inflatable membrane 6 in a direction approximately parallel to the ground, such as Figure 1 and Figure 3 As shown, part of the water supply branch pipe 21 is arranged along the center line 61 of the inflatable membrane 6 in the top view direction and extends along the preset first direction, and part of the water supply branch pipe 21 extends along the preset second direction, wherein 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 pipe 21, water accumulation in the water supply branch pipe 21 can be effectively prevented. Figure 1 As shown in the middle direction A, the preset second direction is as follows Figure 1 As shown in the direction B.

[0056] In some specific embodiments, the water supply system 1 further includes a water supply heating device 15, which is connected to the end of the water supply main 12 connected to the external water source and is communicatively connected to the monitoring system 3. The provision of the water supply heating device 15 heats the cleaning water, enabling the use of hot water to clean snow from the surface of the inflatable membrane 6, effectively accelerating the melting and sliding of the snow and improving the efficiency of snow cleaning.

[0057] In some specific embodiments, the water supply system 1 further includes a system controller 16 and control valves 17, and all control valves 17 are communicatively connected to the system controller 16. Part or all of the water supply main pipes 12 are provided with control valves 17; and / or part or all of the water supply branch pipes 21 are provided with control valves 17. In a specific embodiment, the connection relationship between the water supply main pipe 12 and each device in the water supply system 1 is shown in FIG. Figure 1 shown.

[0058] In actual application, when the surface area of ​​the inflatable membrane 6 is large, the problem of different snow thicknesses on different areas of the surface of the inflatable membrane 6 may arise. The control valve 17 can be an electric control valve 17. The user can operate the system controller 16 to batch or quickly open or close the control valves 17 on each water supply main pipe 12 or water supply branch pipe 21. In an actual application process, since the inflatable membrane 6 is an arc-shaped surface, the thickness of snow at different positions on the surface of the inflatable membrane 6 may be different. Therefore, the time required to clear the snow at different positions is also different. The user can observe the process of clearing snow. When the snow in a certain area has completely melted or slid off, the user can control the control valve 17 corresponding to the water supply branch pipe 21 in this area to close, while keeping the control valves 17 corresponding to the water supply branch pipes 21 in other areas that have not been cleaned open. This can target a local position on the inflatable membrane 6 and save cleaning resources.

[0059] In a specific application, the system controller 16 can also be connected to the monitoring system 3 and the water supply heating device 15. After the temperature sensor 32 in the monitoring system 3 detects the temperature of the external environment or the temperature of the surface of the inflatable membrane 6 from the outside, it sends this data to the system controller 16. The system controller 16 further calculates the target temperature that the water supply heating device 15 needs to heat the cleaning water based on this data and sends it to the water supply heating device 15. The water supply heating device 15 heats the cleaning water. When the cleaning water reaches the target temperature, the water pump 11 further transports the cleaning water from the water supply main pipe 12 to the water supply branch pipe 21, forming a jet of water at the water outlet structure 22 to clean the snow on the surface of the inflatable membrane 6. By spraying hot water on the surface of the inflatable membrane 6 and the snow, the snow in contact with the surface of the inflatable membrane 6 is melted, and part or all of the snow on the surface of the inflatable membrane 6 is melted, so that the snow slides along the surface of the inflatable membrane 6 under the action of gravity and water flow, which can greatly accelerate the melting speed of the snow and improve the efficiency of snow cleaning.

[0060] In a specific application process, the surface of the inflatable membrane 6 can be divided into multiple snow accumulation areas 5, each snow accumulation area 5 is connected to a water supply branch pipe 21, and each water supply branch pipe 21 is connected to multiple water outlet structures 22. The spraying ranges of different water outlet structures 22 can cover different positions on the snow accumulation area 5. In some practical applications, the spraying ranges between the water outlet structures 22 can also overlap with each other.

[0061] In some specific embodiments, the water supply system 1 further includes a filter device 19, and the water supply main pipe 12 is connected to an external water source through the filter device 19. By using the filter device 19 to filter the cleaning water entering the water supply main pipe 12, impurities in the cleaning water can be reduced, further reducing the risk of clogging of the pipe and the water outlet structure 22.

[0062] In some specific embodiments, a fastener 41 and an anti-slip device 42 are also included. The water supply branch pipe 21 and the external cable net 4 structure on the surface of the inflatable membrane 6 are fixedly connected to the surface of the inflatable membrane 6 through the fastener 41; 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 external cable net 4 structure. In an application process, Figure 3 As shown, an external cable net 4 structure is provided on the surface of the inflatable membrane 6, as shown in FIG. Figure 4 As shown, the fastener 41 is a U-shaped fastener. Through the U-shaped fastener, the water supply branch pipe 21 can be cross-engaged with the external cable net 4 structure, which makes the connection between the water supply branch pipe 21 and the surface of the inflatable membrane 6 more stable. While the water outlet structure 22 sprays out cleaning water, it can still maintain a close connection with the surface of the inflatable membrane 6.

[0063] This embodiment provides an inflatable membrane surface snow-prevention device. By providing a water supply system and a cleaning system, a water outlet structure can be used to spray cleaning water onto the surface of the inflatable membrane, causing accumulated snow to melt and slide off the surface of the membrane, thereby achieving efficient snow removal from the membrane surface. Furthermore, by providing a monitoring system, a system controller, and control valves, the snow removal process on the inflatable membrane surface can be automated. By providing a water supply heating device and a snow-melting agent addition device, the melting rate of snow on the membrane surface can be further accelerated. There is no need to manually climb onto the inflatable membrane surface to collect snow, eliminating the high-altitude risks of manual snow removal during snowfall, significantly improving safety and reducing unnecessary labor costs. Furthermore, an air compressor is provided to effectively address the problem of residual water in the water supply main and branch pipes, protecting the inflatable membrane and the device itself, reducing the threat posed to the inflatable membrane by severe weather such as wind and snow, and maintaining the cleanliness of the membrane surface.
