Description

Technical Field

[0001] This application relates to the technical field of air film equipment, and particularly relates to an air film equipment with an automatic smoke exhaust system. Background Art

[0002] Air film equipment is a new type of equipment that uses high-strength polyurethane-coated polyester cloth or polyester film as the main material and inflates it into a spatial structure through inflation. It has the advantages of light weight, flexibility, energy saving, etc., and is widely used in stadiums, warehouses, exhibition halls, event tents and other fields.

[0003] In recent years, under the guidance of various policies, the air film equipment industry has developed rapidly, and a large number of air film equipment with large spans and large spaces have emerged. These air film equipment are often used to store materials. As the volume of the air film equipment becomes larger and the stored materials become more, the fire protection problem of the air film equipment has increasingly attracted people's attention. When a fire breaks out, thick smoke is likely to pose a threat to the lives and property safety of the staff. In the prior art, some air film equipment usually has smoke exhaust openings. If the smoke exhaust openings are always open during use, a large amount of air leakage will occur, increasing the energy consumption of the air film main body. If the smoke exhaust openings are closed, they need to be manually opened during a fire, but manual control is not sensitive enough, and it is often discovered only after the fire is serious, and the losses caused at this time are already relatively serious. Moreover, since the internal space of the air film equipment is often relatively airtight, there are easily smoke exhaust dead corners, poor smoke exhaust, low smoke exhaust efficiency, and thick smoke cannot be discharged in time and effectively.

[0044] Embodiment

[0045] An embodiment of the present application provides a pneumatic film device with an automatic smoke exhaust system, as Figures 1 to 6 shown, including: a pneumatic film main body 1, a smoke exhaust device 2, a monitoring device 3, and a control device 4. The arrows in the figure are the simulated flow directions of the flue gas;

[0046] The smoke exhaust device 2 includes a smoke exhaust valve 21 and a smoke exhaust belt 22. The smoke exhaust device 2 is used to form a smoke exhaust passage 23 on the outer surface of the pneumatic film main body 1 and discharge the flue gas in the smoke exhaust passage 23 through the smoke exhaust valve 21;

[0047] The smoke exhaust passage 23 includes a passage separately formed inside the smoke exhaust belt 22 and a passage jointly formed between the smoke exhaust belt 22 and the outer surface of the air film main body 1; the smoke exhaust valve 21 is installed on the air film main body 1 and connected to one or at least two smoke exhaust belts 22 to communicate with the smoke exhaust passage 23; at least two smoke exhaust holes 12 are formed on the air film main body 1, and the inside of the air film main body 1 communicates with the smoke exhaust passage 23 through the smoke exhaust holes 12, and the smoke exhaust passage 23 communicates with the outside through the smoke exhaust valve 21;

[0048] Specifically, in some embodiments of the present application, the smoke exhaust holes 12 corresponding to the ranges of the respective smoke exhaust belts 22 are uniformly distributed along the extending direction of the respective smoke exhaust belts 22.

[0049] It can be understood that a smoke exhaust passage 23 for exhausting smoke from the air film device can be formed between the smoke exhaust belt 22 and the outer surface of the air film main body 1. By opening and closing the smoke exhaust valve 21, the connection and closing of each smoke exhaust passage 23 can be separately controlled, improving the flexibility of use of the automatic smoke exhaust system of the air film device; when there is no smoke exhaust requirement usually, the smoke exhaust valve 21 is in a closed state, and the gas inside the air film main body 1 does not exchange with the outside or reduces the exchange of gas with the outside, reducing the air supply pressure of the air film device and unnecessary energy consumption.

[0050] Specifically, in some embodiments of the present application, the smoke exhaust passage 23 includes a passage separately formed inside the smoke exhaust belt 22. At this time, the smoke exhaust belt 22 includes a pipeline and openings (not shown in the figure) provided on the pipeline, and all the openings correspond one-to-one to the smoke exhaust holes 12 provided on the air film main body 1. Through the connection between the openings and the exhaust holes, the connection between the smoke exhaust passage 23 and the inside of the air film main body 1 is realized.

[0051] Specifically, in some embodiments of the present application, at least one smoke exhaust hole 12 corresponds to the area of each smoke exhaust belt 22, and at least one smoke exhaust hole 12 also corresponds to the area of each smoke exhaust valve 21.

[0052] At least one smoke exhaust hole 12 corresponds to the area of each smoke exhaust belt 22, and at least one smoke exhaust hole 12 also corresponds to the area of each smoke exhaust valve 21, which can expand the control area of smoke exhaust of each smoke exhaust valve 21, thereby improving the smoke exhaust efficiency.

[0053] The control device 4 is respectively communicatively connected to the smoke exhaust valve 21 and the monitoring device 3 to obtain the smoke state inside the air film main body 1 monitored by the monitoring device 3 and control the opening and closing of the smoke exhaust valve 21.

[0054] Exemplarily, the control device 4 may include any one of a microcontroller, a single-chip microcomputer, a system controller, and an embedded system controller.

[0055] The monitoring device 3 can monitor the smoke state inside the air film main body 1 in real time, which helps to detect dangerous situations such as fires in a timely manner; the smoke exhaust system can automatically open the smoke exhaust channel 23 when detecting smoke by automatically controlling the smoke exhaust valve 21, which can effectively exhaust the smoke in a timely manner, improve the smoke exhaust efficiency, control the deterioration of the dangerous situation, and enhance the safety performance.

[0056] Specifically, in some embodiments of the present application, when the monitoring device 3 monitors that the flue gas in the air film main body 1 exceeds the normal concentration, that is, when the smoke state is abnormal, it will send a signal to the control device 4 and give an alarm. When the control device 4 receives the smoke abnormality alarm signal, it controls the smoke exhaust valve 21 to open for smoke exhaust; when the monitoring device 3 monitors that the smoke concentration in the air film main body 1 returns to normal, the monitoring device 3 ends the alarm and sends a signal to the control device 4. The control device 4 obtains the information that the smoke concentration has returned to normal and controls the smoke exhaust valve 21 to close to stop smoke exhaust.

[0057] Further, as Figure 3 shown in Figure 4 , one or at least two installation areas 11 for installing the smoke exhaust device 2 are preset on the outer surface of the air film main body 1, and all the installation areas 11 cover the outer surface of the air film main body 1, and all the smoke exhaust belts 22 are arranged on each installation area 11.

[0058] Preferably, all the installation areas 11 uniformly cover the outer surface of the air film main body 1, and all the smoke exhaust belts 22 are uniformly arranged on each installation area 11.

[0059] Specifically, in some embodiments of the present application, all the smoke exhaust belts 22 are uniformly arranged along the extending direction of each installation area 11 to form a smoke exhaust belt 22 array to improve the smoke exhaust efficiency;

[0060] The installation area 11 can reduce the installation and positioning calibration time of the smoke exhaust belt 22 and the smoke exhaust valve 21, which helps to improve the installation efficiency. By presetting the installation area 11, after the smoke exhaust belt 22 and the smoke exhaust valve 21 are installed on the installation area 11, the outer surface of the air film main body 1 can be covered, and a smoke exhaust device 2 array can also be formed. On the one hand, it helps to reduce the smoke exhaust dead angle and avoid local smoke retention, so that the flue gas inside the air film main body 1 can be effectively exhausted in time; on the other hand, the smoke exhaust device 2 is uniformly arranged on the outer surface of the air film main body 1 and is arranged in an array scale, which can expand the effective smoke exhaust area and improve the smoke exhaust efficiency without increasing the number of the smoke exhaust devices 2.

[0061] The outer surface of the air film main body 1 includes a flat area 13 at the top and an inclined area 14 around it;

[0062] Each installation area 11 is at least partially located within the gentle area 13. The extending direction of the installation area 11 is the same as or approximately the same as the span direction of the air film main body 1, or the extending direction of the installation area 11 is the same as or approximately the same as the length direction of the air film main body 1; all the smoke exhaust holes 12 are distributed along the extending direction of the installation area 11.

[0063] Preferably, all the smoke exhaust holes 12 are evenly distributed along the extending direction of the installation area 11.

[0064] It can be understood that the uniform distribution of the smoke exhaust holes 12 and the distribution of all the smoke exhaust holes 12 along the extending direction of the installation area 11 are both helpful for realizing the effective discharge of the flue gas in the air film main body 1, avoiding the situation of excessive local flue gas concentration, and enhancing the stability of the flue gas discharge; the installation area 11 being located in the gentle area 13 can reduce the obstruction of the air film main body 1 to the discharge of the flue gas, reduce the smoke blocking phenomenon on the smoke exhaust belt 22, help the smooth discharge of the flue gas, thereby increasing the discharge speed of the flue gas and improving the smoke exhaust efficiency; the smoke exhaust holes 12 in the gentle area 13 can reduce the fluctuation of the air film main body 1, making the air film main body 1 more stable, which is beneficial to the subsequent treatment or utilization process; the gentle area 13 is also helpful for the stability of the connection of the smoke exhaust device 2 and reduces the possibility of the smoke exhaust device 2 falling off.

[0065] Furthermore, there is a strip-shaped smoke exhaust channel 23 arranged along the extending direction of the installation area 11 within each installation area 11. The smoke exhaust belts 22 of the smoke exhaust channel 23 and the smoke exhaust valves 21 are arranged at intervals in turn. The smoke exhaust belts 22 include at least two, and the smoke exhaust valves 22 include at least one.

[0066] Specifically, as Figure 6 shown in the setting method of the third column from left to right in, all the smoke exhaust valves 21, all the smoke exhaust belts 22, and all the smoke exhaust holes 12 are communicated with each other, and the arrangement at intervals in turn means that there is a smoke exhaust valve 21 communicated between two adjacent smoke exhaust belts 22. The above setting method enables the smoke exhaust channel 23 to cover the entire installation area 11, makes full use of the space on the surface of the air film main body 1, effectively solves the problem of unsmooth local smoke exhaust, and improves the smoke exhaust efficiency; however, once a certain smoke exhaust belt 22 or smoke exhaust valve 21 fails, the control of the entire smoke exhaust channel 23 is lost.

[0067] Furthermore, as Figures 2 to 4 shown in and 6, at least two smoke exhaust channels 23 are arranged within each installation area 11, that is, some of the smoke exhaust valves 21 are communicated with some of the smoke exhaust belts 22 and are located at different positions. All the smoke exhaust channels 23 are distributed along the extending direction of the installation area 11.

[0068] Preferably, all the smoke exhaust channels 23 are evenly distributed along the extending direction of the installation area 11.

[0069] Through symmetric distribution, the smoke exhaust channel 23 covers the entire span area of the air film main body 1, making the smoke exhaust capacity more balanced within the entire span area of the air film main body 1, and thus achieving a more uniform smoke exhaust effect; the symmetric distribution of the smoke exhaust channel 23 also helps to reduce the occurrence of smoke exhaust dead corners or excessive local concentrations on the surface of the air film main body 1, and balances the smoke passing volume of each smoke exhaust channel 23; at the same time, through at least two symmetric smoke exhaust channels 23, without affecting the coverage range of the smoke exhaust area, the setting cost of the smoke exhaust valve 21 and the smoke exhaust belt 22 can be reduced, making the smoke exhaust in the entire area of the air film main body 1 more comprehensive and efficient, thereby improving the smoke exhaust efficiency.

[0070] Of course, the smoke exhaust channel 23 can also be asymmetrically distributed on the installation area 11. For example, when the fan supplies air unidirectionally, considering the flow field distribution inside the air film, the smoke exhaust channel 23 and the smoke exhaust valve 21 can be arranged asymmetrically.

[0071] In addition, if a certain smoke exhaust belt 22 or smoke exhaust valve 21 fails, the other smoke exhaust channels 23 except this smoke exhaust channel 23 can still be effectively controlled.

[0072] Furthermore, as Figure 6 shown, in the setting mode of the fourth column from left to right, the smoke exhaust channel 23 includes at least one smoke exhaust valve 21 and at least two smoke exhaust belts 22, and all the smoke exhaust belts 22 are distributed along the circumference of the smoke exhaust valve 21.

[0073] Preferably, all the smoke exhaust belts 22 are evenly distributed along the circumference of the smoke exhaust valve 21.

[0074] That is, the smoke exhaust belts 22 are cross - arranged with the smoke exhaust valve 21 as the center. Exemplarily, in some embodiments of the present application, the smoke exhaust belts 22 are cross - arranged in a cross shape with the smoke exhaust valve 21 as the center. Of course, no limitation is made on the specific number of the smoke exhaust belts 22.

[0075] The design that all the smoke exhaust belts 22 are distributed along the circumference of the smoke exhaust valve 21 increases the lateral area of the smoke absorption area of each smoke exhaust channel 23, and when evenly distributed, it can make the smoking and smoke exhaust capabilities in all directions more balanced, and the smoke can enter from different directions and through different smoke exhaust holes 12, which thus helps to improve the smoke exhaust efficiency.

[0076] It can be understood that the setting modes of the smoke exhaust channels 23 in different installation areas 11 on the same air film device can be the same or different, and no limitation is made on this.

[0077] Furthermore, the shape of the smoke exhaust hole 12 includes any one of a circle, an ellipse, and a rectangle, and the included angle formed between the orientation of each smoke exhaust hole 12 and the ground is between 70 degrees and 100 degrees.

[0078] The angle formed by the orientation of each smoke exhaust hole 12 and the ground is designed according to the characteristics of smoke flow. The arrows in each figure indicate the direction of smoke flow. In a fire, smoke often rises upward. The heat generated by the fire causes the air to expand, which in turn makes the smoke rise. At the same time, the density of smoke is usually smaller than that of air, which also causes a tendency for the smoke to rise. Therefore, in a fire, the main direction of smoke emission is upward. It usually rises along the direction of the flame and gradually spreads to the top or ventilation opening of the air film device.

[0079] The angle formed between the orientation of each smoke exhaust hole 12 and the ground ranges from 70 degrees to 100 degrees, which helps to reduce the blockage of the hole wall of the smoke exhaust hole 12 to the smoke emission, improve the passing efficiency of the smoke, and further promote the circulation of the gas inside the air film device, reducing potential safety hazards.

[0080] Preferably, the orientation of each smoke exhaust hole 12 is perpendicular to the ground, that is, the angle formed between the orientation of each smoke exhaust hole 12 and the ground is 90 degrees.

[0081] Specifically, in some embodiments of the present application, the shape of the smoke exhaust hole 12 is circular. Of course, no specific limitation is imposed on the specific shape of the smoke exhaust hole 12.

[0082] Furthermore, as Figure 5 shown, a sealing structure (not shown in the figure) is provided at the connection between the smoke exhaust valve 21 and the smoke exhaust belt 22. An eaves-shaped waterproof structure 211 is provided at the top of the smoke exhaust valve 21, and an adjustable ventilation structure 212 is provided inside the smoke exhaust valve 21.

[0083] The setting of the sealing structure can effectively prevent gas from leaking from the connection between the smoke exhaust valve 21 and the smoke exhaust belt 22, thereby reducing the possibility of gas leakage, reducing energy consumption, and improving the control effect of the smoke exhaust valve 21. The eaves-shaped waterproof structure 211 can effectively prevent rainwater or other water vapor from entering the inside of the smoke exhaust system from the top of the smoke exhaust valve 21, avoiding the smoke exhaust system from getting damp, rusting or being damaged, and extending the service life of the smoke exhaust system.

[0084] Optionally, in some embodiments of the present application, the sealing structure can be a rubber sealing strip. By using the elasticity and sealing property of the rubber, the connection is ensured to be airtight to prevent smoke from leaking. It can also be a metal sealing gasket, which forms a sealing effect through pressing or threaded connection to prevent smoke from leaking. It can also be sealant. Sealant is coated at the connection between the smoke exhaust valve 21 and the smoke exhaust belt 22. By using the viscosity and high-temperature resistance of the sealant, the gaps at the connection are filled to achieve a sealing effect.

[0085] The adjustable ventilation structure 212 can adjust the passing efficiency of the gas, and can also adjust the opening angle through an accurate control system, so as to effectively control the ventilation volume and smoke exhaust speed of the smoke exhaust passage 23, which helps to make flexible adjustments according to actual needs to adapt to different smoke exhaust requirements; especially in case of a fire, the adjustable ventilation structure 212 can improve the smoke exhaust speed and the smoke exhaust efficiency of the smoke exhaust valve 21.

[0086] Specifically, in some embodiments of the present application, the adjustable ventilation structure 212 is an electric louver. Of course, no limitation is made on the specific form of the adjustable ventilation structure 212.

[0087] Further, it further includes a fire alarm system (not shown in the figure);

[0088] As Figure 2 shown, the monitoring device 3 includes one or at least two. At least two monitoring devices 3 are circumferentially distributed along the inner wall of the air film main body 1 to sense the smoke state inside the air film main body;

[0089] Preferably, at least two monitoring devices 3 are evenly distributed along the circumferential direction of the inner wall of the air film main body 1.

[0090] It can be understood that through the distribution of at least two monitoring devices 3, the situation inside the air film main body 1 can be monitored more comprehensively and effectively, potential problems can be detected in time and corresponding measures can be taken. The distribution of at least two monitoring devices 3 can also improve the accuracy and reliability of smoke monitoring, and further improve the smoke exhaust stability of the automatic smoke exhaust system of the air film main body 1.

[0091] The control device 4 is also connected to the fire alarm system to obtain the smoke state data sensed by the monitoring device 3, and when the smoke state data conforms to the set threshold of the smoke state generated by the fire, the automatic smoke exhaust system is turned on.

[0092] Exemplarily, the fire alarm system may include a monitoring device, an alarm signal device, a fire extinguishing device, etc.; when a fire occurs, the fire alarm system can start the alarm signal device to give an alarm in the form of sound and light, and extinguish the fire by means of dry powder, gas, liquid, etc.

[0093] Exemplarily, the set threshold may be the smoke concentration. When the smoke concentration in the smoke state data obtained by the monitoring device 3 conforms to the set threshold, it indicates that a fire has occurred.

[0094] Further, it further includes a user terminal (not shown in the figure);

[0095] The user terminal is communicatively connected to the control device 4 for remotely controlling or locally controlling the operation of the automatic smoke exhaust system.

[0096] Specifically, in some embodiments of the present application, the user terminal may be a smart phone, a tablet computer or a dedicated control panel, so that the user can monitor and adjust the environment and devices inside the air film device;

[0097] The user can input a control command through the user terminal to conduct a daily inspection on whether the automatic smoke exhaust system can operate normally.

[0098] Further, the monitoring device 3 includes one or at least two of a photoelectric smoke sensor, an ionization smoke sensor, and a light scattering smoke sensor.

[0099] It can be understood that different types of smoke sensors have different detection principles for smoke. Comprehensive adoption can more comprehensively monitor the smoke situation inside the structure, including smoke of different particle sizes and types; different types of sensors have different sensitivities and response speeds to smoke. Comprehensive use can improve the detection accuracy and reduce the possibility of false alarms and missed alarms; using at least two types of sensors for monitoring can conduct multiple verifications, improve the credibility of the monitoring results, and enhance the authenticity and reliability of the monitoring; different types of sensors also have different adaptabilities in different environments. Comprehensive use can enhance the adaptability of the automatic smoke exhaust system in various complex environments.

[0100] Further, a cable structure 15 for restricting the shape of the air film main body 1 is also provided outside the air film main body 1.

[0101] The cable structure 15 can effectively restrict the shape of the air film main body 1, keep it in the required shape and structure, and further enhance the stability and wind resistance of the air film main body 1.
