Description

Technical Field

[0001] This application relates to the technical field of fire safety, and particularly to a suspended fire extinguishing mechanism and a large-space radiant heating device. Background Art

[0002] In daily production and life, in order to eliminate potential fire safety hazards, a suspended dry powder fire extinguishing device, commonly known as a fire extinguishing ball, is often installed on the top of a building or the housing of a large device.

[0003] The inside of the tank body of the fire extinguishing ball is filled with dry powder fire extinguishing materials and gas (such as nitrogen, etc.); the top of the fire extinguishing ball is connected to the top of the building or the housing of the device through a hanging ring, and a pressure gauge and a heat-sensitive glass tube are arranged at the bottom of the fire extinguishing ball. When an open fire occurs below the fire extinguishing ball, the temperature below the fire extinguishing ball gradually rises until the heat-sensitive glass tube bursts due to high temperature, the seal at the nozzle of the tank body fails, and the dry powder material inside the tank body is ejected under the action of nitrogen to extinguish the fire.

[0004] When the installation height of the fire extinguishing ball is relatively high from the ground, if the ignition point starts from a low position of the building or the housing of the device, it is difficult for the heat-sensitive glass tube to sense the temperature change in the bottom space, and it cannot burst and trigger in time when the fire is relatively small, which is likely to cause the spread of the fire. After the fire spreads for a period of time, the temperature in the top space can rise, and at this time, the heat-sensitive glass tube bursts and releases the dry powder material, which has a relatively low effect on controlling the fire. Content of the Utility Model

[0007] A fire extinguishing ball assembly, on which a triggering member is provided;

[0008] A force application assembly, the force application assembly includes a striking member, a traction member, and a hanging member. The striking member is arranged opposite to the triggering member, the striking member is movably arranged, and the striking member always has a tendency to move towards the triggering member; one end of the traction member is connected to the striking member, and a hanging member is provided at the other end of the traction member. The hanging member is lower than the triggering member, and the hanging member always has a tendency to move the striking member away from the triggering member.

[0009] Optionally, the force application assembly further includes an elastic member, and the elastic member is connected to the striking member, and the elastic member always has a tendency to move the striking member closer to the triggering member.

[0010] Optionally, the striking member includes a bent portion and a sharp portion. The bent portion matches the outer contour of the fire extinguishing ball assembly, and the bottom end of the bent portion extends towards the triggering member. The sharp portion is connected to the bottom end of the bent portion and is disposed opposite to the triggering member.

[0011] Optionally, the suspended fire extinguishing mechanism further includes a limiting assembly. The limiting assembly includes a plurality of limiting members sequentially arranged along the outer periphery of the fire extinguishing ball assembly. The limiting members are provided with limiting chutes, and the striking member penetrates through the limiting chutes.

[0012] Optionally, the number of the force applying assemblies is multiple, and the multiple force applying assemblies are arranged in central symmetry with the triggering member as the center.

[0013] Optionally, the multiple force applying assemblies are arranged in pairs opposite to each other. The sharp portions of the two striking members arranged opposite to each other have opposite magnetic polarities, and the triggering member is located between the two sharp portions with opposite magnetic polarities.

[0014] Optionally, the suspended fire extinguishing mechanism further includes a pulley assembly. The pulley assembly is arranged in one-to-one correspondence with the force applying assembly, and the traction member is wound around the pulley assembly.

[0015] Optionally, the pulley assembly includes a fixed pulley. The traction member includes a radial traction section and a vertical traction section. The radial traction section extends along the radial direction of the fire extinguishing ball assembly, and one end of the radial traction section is connected to the striking member. The radial traction section and the vertical traction section are connected at the fixed pulley, and the end of the vertical traction section is connected to the hanging member.

[0016] Optionally, the suspended fire extinguishing mechanism further includes a hanging assembly. The hanging assembly includes a plurality of hanging brackets, and the hanging brackets are used to connect to the fire extinguishing ball assembly, the force applying assembly or the pulley assembly.

[0017] In a second aspect, the present application provides a large-space radiant heating device, which includes the suspended fire extinguishing mechanism provided in the first aspect of the present application, and further includes a device housing. A combustion chamber is provided inside the device housing, the suspended fire extinguishing mechanism is arranged inside the device housing, and a preset distance is provided between the hanging member and the bottom of the device housing.

[0018] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art:

[0019] The suspension fire extinguishing mechanism provided by the embodiment of the present application can apply an external force to the trigger member in the fire extinguishing ball assembly through the force application assembly to trigger the fire extinguishing ball assembly. Specifically, the striking member in the force application assembly always has a tendency to move towards the trigger member. When the striking member is not affected by other external forces, the striking member can move towards the trigger member and break the trigger member to trigger the fire extinguishing ball assembly. One end of the traction member is connected to the striking member, and a hanging member is provided at the other end of the traction member. The hanging member is lower than the trigger member, and the hanging member always has a tendency to move the striking member away from the trigger member. The hanging member can apply an external force to the striking member through the traction member to overcome the tendency of the striking member to move towards the trigger member and prevent the striking member from contacting the trigger member under normal conditions, resulting in abnormal triggering of the fire extinguishing ball assembly. Since the hanging member is lower than the trigger member, when a fire breaks out at the bottom of a building or the bottom of a large device housing, the open fire at a low position will melt the hanging member or the bottom end of the traction member, resulting in the disappearance of the external force applied by the hanging member to the striking member through the traction member. The striking member will move towards the trigger member and break the trigger member to trigger the fire extinguishing ball assembly in a timely manner, enabling timely detection of the low-position fire source, facilitating control of the fire at the early stage of the fire occurrence, and preventing the spread of the fire.

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0041] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0042] For ease of description, spatially relative terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms such as "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or motion state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "upper" other elements or features. Therefore, the example term "below" can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative descriptors used in the text are interpreted accordingly.

[0043] To solve the technical problem in the prior art that when the installation height of the suspended fire extinguishing device is relatively high, it is difficult to trigger and control the fire in a timely manner, the present application provides a suspended fire extinguishing mechanism and a large-space radiant heating device. When the fire extinguishing ball assembly 1 is installed at a high position, the hanging member 23 and the traction member 22 below the fire extinguishing ball assembly 1 in the force application assembly 2 can sense a fire source at a low position. When the bottom end of the hanging member 23 or the traction member 22 is melted by an open fire at a low position, the striking member 21 connected to the traction member 22 can move towards the trigger member 11 of the fire extinguishing ball assembly 1. After breaking the trigger member 11, the fire extinguishing material inside the fire extinguishing ball assembly 1 can be ejected, enabling the timely triggering of the fire extinguishing ball assembly 1 when the fire is at a low level, which is beneficial to timely controlling the fire and preventing the spread of the fire.

[0044] Please refer to Figures 1 to 7 , in the first aspect of the embodiment of the present application, a suspended fire extinguishing mechanism is provided, including a fire extinguishing ball assembly 1 and a force application assembly 2, as Figure 1 and Figure 2As shown in the figure. Among them, the tank body 12 of the fire extinguishing ball assembly 1 is filled with fire extinguishing materials and gas. A trigger 11 is provided on the fire extinguishing ball assembly 1. When the trigger 11 is broken, the fire extinguishing materials inside the tank body 12 are ejected downward under the action of the gas. Specifically, the fire extinguishing ball assembly 1 can adopt a hanging dry powder fire extinguishing device in the prior art. The trigger 11 is a heat-sensitive glass tube in the hanging dry powder fire extinguishing device, and the trigger 11 is arranged in the valve seat 13 at the bottom of the tank body 12.

[0045] Please refer to Figure 1 、 Figure 5 and Figure 6 , the force application assembly 2 includes a striking member 21, a traction member 22 and a hanging member 23. The striking member 21 is arranged opposite to the trigger 11. The striking member 21 is movably arranged and can move relative to the trigger 11, so that the striking member 21 moves away from or approaches the trigger 11. And the striking member 21 always has a tendency to move towards the trigger 11. When the striking member 21 is not affected by other external forces, the striking member 21 can move towards the trigger 11 and break the trigger 11 to realize the triggering of the fire extinguishing ball assembly 1. One end of the traction member 22 is connected to the striking member 21, and a hanging member 23 is provided at the other end of the traction member 22. The hanging member 23 is lower than the trigger 11, and the hanging member 23 always has a tendency to move the striking member 21 away from the trigger 11. Specifically, the hanging member 23 can apply an external force to the striking member 21 through the traction member 22 to overcome the tendency of the striking member 21 to move towards the trigger 11, and prevent the striking member 21 from contacting the trigger 11 under normal conditions, resulting in abnormal triggering of the fire extinguishing ball assembly 1.

[0046] It should be noted that the hanging member 23 is a heavy object with a certain mass. By applying an external force to the striking member 21 through the gravity of the hanging member 23, the striking member 21 can be in a static state of force balance, so that the striking member 21 remains stationary relative to the trigger 11 under normal conditions. When the fire extinguishing ball assembly 1 is installed at a high place through the hanging ring 14, since the hanging member 23 is lower than the trigger 11, when a fire breaks out at the bottom of the building or the bottom of the large device housing 6, the open fire at a low place will melt the hanging member 23 or the bottom end of the traction member 22, resulting in the disappearance of the external force applied by the hanging member 23 to the striking member 21 through the traction member 22. The striking member 21 will move towards the trigger 11 and break the trigger 11, realizing the timely triggering of the fire extinguishing ball assembly 1, and can timely sense the low place fire source, which is beneficial to controlling the fire at the early stage of the fire and preventing the spread of the fire.

[0047] It should be noted that the hanging member 23 and the traction member 22 can be made of a low-melting-point material (with a melting point lower than 300°C, preferably 100°C - 200°C) to accelerate the melting speed of the hanging member 23 and / or the traction member 22. When the gravity of the hanging member 23 decreases due to melting, the external force exerted on the striking member 21 is reduced; when the traction member 22 is melted and broken, the connection between the hanging member 23 and the striking member 21 fails, and the external force exerted by the hanging member 23 on the striking member 21 completely disappears; in both of the above two cases, the force balance state of the striking member 21 will be broken. At this time, the tendency of the striking member 21 to move towards the triggering member 11 is greater than the tendency to move away from the triggering member 11, and the striking member 21 will move towards the triggering member 11 and break the triggering member 11.

[0048] In the above embodiment, since the traction member 22 is a flexible member, the gravity in the vertical direction provided by the hanging member 23 can be converted into a horizontal or inclined tension by bending the flexible member. It is only necessary to set a corner support or a pulley at the bending position of the flexible member (i.e., the traction member 22) to achieve the force commutation, so that the striking member 21 has a tendency to move away from the triggering member 11 under the gravity of the hanging member 23, as Figure 1 、 Figure 5 and Figure 6 shown.

[0049] In some embodiments of the present application, please refer to Figure 1 、 Figure 5 and Figure 6 . In order to make the striking member 21 have a tendency to move towards the triggering member 11 when not subjected to an external force, the force application assembly 2 further includes an elastic member 24. The elastic member 24 is connected to the striking member 21 and always has a tendency to make the striking member 21 approach the triggering member 11. Specifically, when the hanging member 23 and the traction member 22 pull the striking member 21 to the outside of the triggering member 11, the elastic member 24 undergoes elastic deformation. The elastic member 24 is rigidly connected to the striking member 21, and the elastic force of the elastic member 24 causes the striking member 21 to have a tendency to move towards the triggering member 11. When the external force exerted by the hanging member 23 and the traction member 22 on the striking member 21 decreases or is reduced, the elastic member 24 returns to its original state under the action of the elastic force and drives the striking member 21 to move towards the triggering member 11, so as to facilitate the striking member 21 to trigger the fire extinguishing ball assembly 1.

[0050] It should be noted that the elastic member 24 can be a spring or a spring sheet extending in the vertical direction. When the striking member 21 is subjected to a horizontal traction force, the elastic member 24 undergoes bending deformation under the pulling action of the striking member 21. When the hanging member 23 or the traction member 22 melts, the pulling force exerted by the striking member 21 on the elastic member 24 also decreases or disappears. The elastic member 24 returns from the bent deformation state to the vertical state and drives the striking member 21 to move horizontally, so that the striking member 21 gradually approaches and breaks the triggering member 11.

[0051] In some other embodiments of the present application, in order to make the striking member 21 have a tendency to move towards the triggering member 11 when not subjected to an external force, in addition to the connection method through the elastic member 24 described above, the striking member 21 can also be inclined and hung by a rope. When the pulling force of the traction member 22 on the striking member 21 decreases or disappears, under the action of the gravity of the striking member 21, the rope will swing from an inclined state to a vertical state. At this time, the striking member 21 can move towards the triggering member 11 under its own gravity.

[0052] However, when the striking member 21 is inclined and hung by a rope, the swinging amplitude of the striking member 21 is relatively large, and it is easy to be misaligned with the triggering member 11, and the fire extinguishing ball assembly 1 cannot be triggered. Therefore, it is preferably connected to the striking member 21 through the elastic member 24, so that the striking member 21 has a tendency to move towards the triggering member 11 when not subjected to an external force.

[0053] In some embodiments of the present application, please refer to Figure 5 , the striking member 21 includes a bent portion 211 and a sharp portion 212. The bent portion 211 matches the outer contour of the fire extinguishing ball assembly 1, and the bottom end of the bent portion 211 extends towards the triggering member 11. The sharp portion 212 is connected to the bottom end of the bent portion 211, and the sharp portion 212 is disposed opposite to the triggering member 11. Since the valve seat 13 of the triggering member 11 is disposed in the central area at the bottom of the tank body 12, in order to prevent the striking member 21 from being blocked by the tank body 12 when moving towards the triggering member 11, the sharp portion 212 is extended to an area close to the triggering member 11 through the bent portion 211, which can avoid interference between the striking member 21 and the tank body 12 and reduce the distance that the striking member 21 needs to move when breaking the triggering member 11.

[0054] In some embodiments of the present application, please refer to Figure 1 , Figure 5 and Figure 6 , the top end of the bent portion 211 is rigidly connected to the elastic member 24, so that the entire striking member 21 can be driven to move by the deformation or reset of the elastic member 24.

[0055] In some embodiments of the present application, the entire striking member 21 is supported by a high-strength material (such as steel, etc.). The shape of the sharp portion 212 can be set as a pyramid shape or a cone shape, so as to apply a force to the triggering member 11 through the vertex of the pyramid or the cone to break the triggering member 11.

[0056] In some embodiments of the present application, please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6In order to achieve precise matching between the striking member 21 and the trigger member 11, the suspended fire extinguishing mechanism further includes a limiting assembly 3, which includes a plurality of limiting members 31 sequentially arranged along the outer circumference of the fire extinguishing ball assembly 1, and can be used to limit the tank body 12 of the fire extinguishing ball assembly 1 to prevent the tank body 12 from shifting during the hanging process. A limiting slide 311 is provided on the limiting member 31, and the striking member 21 passes through the limiting slide 311. The bent portion 211 of the striking member 21 is slidably arranged in the limiting slide 311, and one end of the limiting slide 311 in the length direction points to the trigger member 11. When the striking member 21 moves toward the trigger member 11, the striking member 21 can be guided by the limiting slide 311.

[0057] For details, please refer to Figure 3 When the limiting member 31 is located on the left side of the tank body 12, the striking member 21 is pulled by the hanging member 23 so that the bent portion 211 is located in the left to middle area of the limiting slide groove 311. When the bottom end of the hanging member 23 or the pulling member 22 is melted, the striking member 21 moves to the right along the length direction of the limiting slide groove 311 under the elastic force of the elastic member 24, so that precise striking between the sharp portion 212 and the trigger member 11 can be achieved.

[0058] In some embodiments of this application, please refer to Figure 1 , Figure 5 and Figure 6 There are multiple force-applying components 2, and the multiple force-applying components 2 are arranged in a centrally symmetrical manner with the trigger component 11 as the center, and the striking components 21 in the multiple force-applying components 2 are arranged opposite to the trigger component 11, and each striking component 21 is correspondingly connected to a hanging component 23, which can form multiple fire source sensing points around the fire extinguishing ball component 1. When any hanging component 23 around the fire extinguishing ball component 1 is melted by an open flame, the fire extinguishing ball component 1 can be triggered, which is beneficial to improving the fire source sensing range of a single suspended fire extinguishing mechanism.

[0059] In some embodiments of this application, please refer to Figure 1 , Figure 5 and Figure 6 The force-applying components 2 are arranged opposite to each other in pairs, and the two oppositely arranged striking members 21 have sharp portions 212 with opposite magnetic properties. The trigger member 11 is located between the two sharp portions 212 with opposite magnetic properties. When the traction effect of the suspension member 23 on one of the striking members 21 fails, the sharp portion 212 of the striking member 21 can have a tendency to move toward the trigger member 11 under the magnetic attraction of the sharp portion 212 on the opposite side, thereby realizing the triggering of the fire extinguishing ball assembly 1.

[0060] It should be noted that when the two oppositely arranged striking members 21 have sharp portions 212 with opposite magnetic polarities, it is possible to make the striking members 21 tend to move towards the triggering member 11 under the action of magnetic force without arranging an elastic member 24 at the top of the bending portion 211. When the traction force exerted by the hanging member 23 on the striking member 21 is balanced with the magnetic force received by the sharp portion 212, the striking member 21 can be kept stationary relative to the triggering member 11.

[0061] In some embodiments of the present application, since the triggering member 11 is arranged in the valve seat 13, and the valve seat 13 only has openings on both sides, as Figure 1 and Figure 2 shown, therefore, it is preferred that the number of the force application assemblies 2 is two, symmetrically arranged on both sides of the fire extinguishing ball assembly 1, and can be used to realize the fire source perception on both sides of the fire extinguishing ball assembly 1, as Figure 1 、 Figure 5 and Figure 6 shown.

[0062] In the above embodiments of the present application, it is necessary to convert the vertical gravity provided by the hanging member 23 into a horizontal traction force through the traction member 22, and a corner support portion or a pulley etc. needs to be arranged at the bending portion of the traction member 22 to realize the force commutation. In order to avoid that when the frictional resistance of the corner support portion to the traction member 22 is relatively large, it forms a resistance to the movement of the striking member 21 towards the triggering member 11. In some preferred embodiments of the present application, the hanging type fire extinguishing mechanism further includes a pulley assembly 4. The pulley assembly 4 is arranged in one-to-one correspondence with the force application assembly 2, and the traction member 22 is wound around the pulley assembly 4. The bending of the traction member 22 and the force commutation are realized through the pulley assembly 4, and the frictional resistance received by the traction member 22 can also be reduced, so as to avoid the movement of the striking member 21 being affected by the frictional resistance of the traction member 22 when the hanging member 23 or the bottom end of the traction member 22 melts, and it can ensure that the striking member 21 can quickly move towards the triggering member 11.

[0063] In some embodiments of the present application, please refer to Figure 1 、 Figure 5 and Figure 6 , the pulley assembly 4 includes a fixed pulley 41. The traction member 22 includes a radial traction section 221 and a vertical traction section 222. The radial traction section 221 extends along the radial direction of the fire extinguishing ball assembly 1. One end of the radial traction section 221 is connected to the striking member 21, which can realize the horizontal traction of the striking member 21, and can also expand the fire source perception range of the hanging type fire extinguishing mechanism in the radial direction; the radial traction section 221 and the vertical traction section 222 are connected at the fixed pulley 41, and the end of the vertical traction section 222 is connected to the hanging member 23. The traction member 22 is bent at the fixed pulley 41, so as to facilitate the commutation of force while transmitting force.

[0064] In some embodiments of the present application, the suspended fire extinguishing mechanism further includes a hanging component 5, and the hanging component 5 includes a plurality of hanging frames, which are used to connect with the fire extinguishing ball component 1, the force application component 2, the limiting component 3 or the pulley component 4. Thus, the suspended installation of each component inside the building or inside the device housing 6 is realized.

[0065] Specifically, the hanging component 5 includes a first hanging frame 51, a second hanging frame 52 and a third hanging frame 53. The hanging frame bodies 511 of the first hanging frame 51, the second hanging frame 52 and the third hanging frame 53 can all be made of channel steel. Each hanging frame body 511 is fixedly arranged on the inner wall of the building wall or the device housing 6 for realizing the installation of each component.

[0066] Among them, the first hanging frame 51 is used to hoist the elastic member 24 and the striking member 21 in the fire extinguishing ball component 1 and the force application component 2. A plurality of columns of connection holes are opened on the hanging frame body 511 of the first hanging frame 51. Each column of connection holes contains a plurality of connection holes. Among them, the first connection hole 512 arranged in the middle of the hanging frame body 511 is used to connect with the fire extinguishing ball component 1. When the length direction of the hanging frame body 511 is parallel to the length direction or the width direction of the building (or the device housing 6), a plurality of fire extinguishing ball components 1 can be sequentially arranged along the length direction or the width direction of the building (or the device housing 6) through the same hanging frame body 511, which is beneficial to expanding the spraying coverage range of the fire extinguishing material of the suspended fire extinguishing mechanism, as Figure 7 shown. Specifically, the fire extinguishing ball component 1 is connected to the first connection hole 512 through a first connecting member 15. To avoid abnormal shaking of the fire extinguishing ball component 1 during use, it is preferred that the first connecting member 15 is a rigid connecting member. Second connection holes 513 are arranged on both sides of the first connection hole 512, which can be used to respectively arrange the elastic member 24 and the striking member 21 on both sides of the fire extinguishing ball component 1. Specifically, the elastic member 24 is connected to the second connection hole 513 through a second connecting member 25, and the second connecting member 25 is also a rigid connecting member.

[0067] The second hanging frame 52 is used to connect with the limiting component 3. The limiting component 3 further includes a third connecting member 32 connected between the limiting member 31 and the second hanging frame 52. The second hanging frame 52 has the same structure as the first hanging frame 51. The difference is only that only one column of connection holes can be arranged on the second hanging frame 52 to realize the connection with the limiting component 3. Since the limiting component 3 needs to remain relatively stationary during use, it is preferred that the third connecting member 32 is a rigid connecting member.

[0068] The structure of the third suspension bracket 53 is the same as that of the second suspension bracket 52 and is used to connect with the fourth connecting member 42 in the pulley assembly 4, so as to realize the fixed installation of the fixed pulley 41. Since the fixed pulley 41 needs to remain relatively stationary during use to avoid affecting the traction member 22 and the striking member 21, it is preferred that the fourth connecting member 42 is a rigid connecting member.

[0069] In some embodiments of the present application, the suspension assembly 5 further includes a fourth suspension bracket 54 provided on the side wall of the building side wall or the device housing 6. The structure of the fourth suspension bracket 54 is the same as that of the third suspension bracket 53. When the hanging member 23 needs to be arranged in the corner area of the building or the device housing 6, the distance between the hanging member 23 and the side wall of the building side wall or the device housing 6 is relatively close. A fifth connecting member 43 extending in the horizontal direction can be provided on the fourth suspension bracket 54. The installation of the fixed pulley 41 can be realized through the fifth connecting member 43, and the winding support of the traction member 22 can also be realized; the fifth connecting member 43 is also a rigid connecting member.

[0070] It should be noted that the third suspension bracket 53 and the fourth suspension bracket 54 can be selected according to the installation area of the hanging member 23, or can be provided at the same time to enhance the installation stability of the fixed pulley 41, such as Figure 1 、 Figure 5 and Figure 6 As shown, the purpose of the present application can be achieved. To prevent the fixed pulley 41 from shaking laterally or longitudinally during use and affecting the force balance state of the striking member 21, it is preferred to connect and fix the fixed pulley 41 through the third suspension bracket 53 and the fourth suspension bracket 54 at the same time, so as to realize the two-way limit of the fixed pulley 41 and improve the stability of the fixed pulley 41.

[0071] It should be noted that in the above embodiments, the first connecting member 15, the second connecting member 25, the third connecting member 32, the fourth connecting member 42 and the fifth connecting member 43 are all preferably rigid connections. For the purpose of realizing convenient assembly, it is preferred that the first connecting member 15, the second connecting member 25, the third connecting member 32, the fourth connecting member 42 and the fifth connecting member 43 are all high-strength through-threaded suspension rods (that is, threads are provided on the outer peripheral surfaces of each connecting member), and matching screw holes can be provided on the components connected to the connecting members to realize the connection. Specifically, when the first connecting member 15 is a high-strength through-threaded suspension rod, the hanging ring 14 on the fire extinguishing ball assembly 1 is detachable, and the end of the first connecting member 15 is directly threadedly connected to the screw hole of the hanging ring 14 on the tank body 12, so as to realize the convenient hoisting of the fire extinguishing ball assembly 1.

[0072] Please refer to Figures 1 to 7, in the second aspect of the present application, a high - space radiant heating device is provided, which includes the suspended fire - extinguishing mechanism in the above - mentioned embodiment, and also includes a device housing 6. Inside the device housing 6, there is a combustion chamber 7. The combustion chamber 7 is respectively connected to a return air pipe 8 and a radiation pipe 9 to form an air - flow circulation loop. When the air flow in the return air pipe 8 enters the combustion chamber 7, after heat exchange and temperature rise inside the combustion chamber 7, the hot air flow is then output through the radiation pipe 9, thereby realizing radiant heating for high - spaces (such as gymnasiums, factory workshops, etc.).

[0073] The suspended fire - extinguishing mechanism is arranged inside the device housing 6. There is a preset distance H between the hanging member 23 and the bottom of the device housing 6. When an open fire leaks inside the device housing 6 during the combustion process of the combustion chamber 7, the hanging member 23 located at a lower position can be used to sense the fire source, so as to trigger the fire - extinguishing ball assembly 1 in a timely manner and control the fire at an early stage of the fire occurrence, such as Figure 5 , Figure 6 and Figure 7 as shown.

[0074] It should be noted that when the hanging member 23 is arranged in the area where people are active, the height of the preset distance H is preferably more than 2 meters to avoid accidental triggering of the fire - extinguishing ball assembly 1 due to human factors; when the hanging member 23 is arranged in the non - personnel - activity area, the preset distance H can be less than 2 meters.

[0075] It should be noted that the suspended fire - extinguishing mechanism in the present application can be installed inside the device housing 6 to ensure the fire safety of the high - space radiant heating device, or can be installed inside high - spaces such as gymnasiums and factory workshops to ensure the fire safety inside the high - spaces.

[0076] Please refer to Figures 1 to 7 , in some embodiments of the present application, the fire - extinguishing method of the above - mentioned suspended fire - extinguishing mechanism includes:

[0077] Step 1: Install the suspended fire - extinguishing mechanism to make the striking member 21 in a force - balanced state. At this time, the elastic member 24 has elastic deformation. There is a horizontal distance between the sharp part 212 of the striking member 21 and the triggering member 11, and the sharp part 212 remains relatively stationary with respect to the triggering member 11.

[0078] Step 2: When a fire occurs, the hanging member 23 and the traction member 22 first come into contact with the fire source at a lower position. The bottom ends of the hanging member 23 and / or the traction member 22 melt. The traction force exerted by the hanging member 23 on the striking member 21 decreases or disappears, and the force - balanced state of the striking member 21 is broken. The tendency of the striking member 21 to move towards the triggering member 11 is greater than the tendency of the striking member 21 to move away from the triggering member 11.

[0079] Step 3: The striking member 21 moves toward the trigger member 11 under the elastic force of the elastic member 24, and the striking member 21 breaks the trigger member 11. The tank body 12 of the fire extinguishing ball assembly 1 sprays the fire extinguishing material under the action of high-pressure gas to control the fire.
