Description

Technical Field

[0001] The present invention relates to the technical field of water-based fire extinguishing agent spraying, and particularly relates to a water-based fire extinguishing agent spraying and extinguishing device. Background Art

[0002] A water-based fire extinguishing agent is a fire extinguishing agent in which certain additives are added to water to improve the fire extinguishing performance of water. During the fire extinguishing process, when the "water-based foam fire extinguishing agent" spreads on the surface of the combustible, liquid is precipitated to cool its surface, and a water film is formed on the surface of the combustible to jointly seal the surface of the combustible with the foam layer, isolating the air to form a heat insulation barrier. The liquid vaporizes after absorbing heat and dilutes the oxygen content in the air on the surface of the combustible, producing an asphyxiating effect on the combustible object and preventing the continuation of combustion. At the same time, the fire extinguishing agent reacts chemically with the combustible substance to form a polymer substance, which can effectively inhibit or reduce the generation of combustion free radicals, break the combustion chain, and prevent combustion.

[0003] The existing spraying of water-based fire extinguishing agents is usually contained in a fire extinguisher. When in use, take the fire extinguisher containing the water-based fire extinguishing agent and spray the water-based fire extinguishing agent. However, traditional fire extinguishers need to be taken from a specific placement location during a fire, and then returned to the fire area for spraying and fire fighting. The water-based fire extinguishing agent cannot be ejected immediately to control the fire situation, and it requires manual operation. Firefighters cannot escape, and the safety is relatively low.

[0004] Therefore, a water-based fire extinguishing agent spraying and extinguishing device has now been developed, which can be set in a fire prevention area and can automatically spray and extinguish the fire with a water-based fire extinguishing agent during a fire, improving the fire extinguishing safety. Summary of the Invention

[0005] In order to overcome the shortcomings that traditional fire extinguishers need to be taken from a specific placement location during a fire, the water-based fire extinguishing agent cannot be ejected immediately to control the fire situation, and it requires manual operation. Firefighters cannot escape, and the safety is relatively low, the present invention provides a water-based fire extinguishing agent spraying and extinguishing device that can be set in a fire prevention area and can automatically spray and extinguish the fire with a water-based fire extinguishing agent during a fire, improving the fire extinguishing safety.

[0006] The technical solution of the present invention is: a water-based fire extinguishing agent spraying and extinguishing device, including a housing, a multi-stage lifting platform, a shunt cylinder, a spray head, a carbon dioxide sensor, a conveying mechanism, and a swinging mechanism.

[0007] Further explanation, the conveying mechanism includes a mounting seat, a recovery disk, a volute spring, a conveying pipe, a clamping piece, a rotating connector, a water pump and a water tank. The mounting seat is connected to the inner side of the lower left part of the outer shell, and the recovery disk is rotatably connected to the mounting seat. A volute spring is connected between the front of the recovery disk and the mounting seat, a clamping piece is connected to the lower part of the multi-stage lifting platform, a rotating connector is connected to the rear side of the recovery disk, a conveying pipe is connected between the rotating connector and the diversion cylinder, the conveying pipe is wound around the recovery disk, the conveying pipe passes through the clamping piece, and the clamping piece and the conveying pipe are squeezed and matched, a water tank is placed on the inner side of the rear of the outer shell, a water pump is connected to the bottom of the outer shell, the water inlet end of the water pump is connected to the water tank through a hose, and the water outlet end of the water pump is connected to the The rotating connector is connected through a conduit. When the multi-stage lifting platform rises, the diverter tube will pull the delivery pipe, so that the recovery plate can rotate to extend the delivery pipe. When the multi-stage lifting platform descends, the scroll spring rebounds to make the recovery plate rotate to reel in the delivery pipe to adapt to the lifting height of the multi-stage lifting platform. When the recovery plate rotates, the rotating connector can keep the water outlet of the water pump connected at all times to avoid affecting the water pump's extraction of the water-based fire extinguishing agent inside the water tank. The water pump introduces the water-based fire extinguishing agent in the water tank into the delivery pipe, and then from the delivery pipe into the diverter tube, and then diverts it through the diverter tube and introduces it into the sprinkler head, which is sprayed out by the sprinkler head to perform a fire extinguishing operation.

[0008] Further explanation, the swing mechanism includes a swing ring, a guide ring, a first spring, a first connecting plate, a pressure piece and an electric push rod. The sprinkler heads are all connected with swing rings, and a plurality of guide rings are connected to the diverter tube. The swing rings are all slidably connected to adjacent guide rings, and the upper and lower parts of the swing rings are connected to the adjacent guide rings with a first spring, the top of the diverter tube is connected to the electric push rod, and the telescopic end of the electric push rod is connected with the pressure piece, and the lower part of the pressure piece passes through the diverter tube and is slidably connected to the diverter tube, and the first connecting plate is rotatably connected to the pressure piece between the swing rings and the pressure piece, and the telescopic end of the electric push rod moves up and down to control the pressure piece to move up and down, and the pressure piece moves up and down to control the swing ring to slide through the first connecting plate, and the swing ring moves up and down in the guide ring to drive the sprinkler head to move up and down, and the sprinkler head moves up and down to increase the spraying range of the water-based fire extinguishing agent.

[0009] Further description, it also includes a shaking mechanism for shaking the water tank to loosen the water base in the water-based fire extinguishing agent, the shaking mechanism includes a guide rod, a shaking plate, a servo motor and a cam, a plurality of guide rods are connected to the bottom of the outer shell, a shaking plate is slidably connected between the guide rods, the water tank can be placed on the shaking plate, a servo motor is connected to the lower right side of the inner shell, a cam is connected to the output shaft of the servo motor, the cam and the shaking plate are squeezed together, the rotation of the servo motor output shaft drives the cam to rotate, the rotating protruding part of the cam repeatedly squeezes the shaking plate, so that the shaking plate drives the water tank to move up and down, the up and down movement of the water tank causes the water-based fire extinguishing agent inside to shake, so that the water base of the water-based fire extinguishing agent is loosened, thereby improving the spraying effect.

[0010] Furthermore, it also includes a diffusion mechanism for increasing the spraying area of the water-based fire extinguishing agent. The diffusion mechanism includes a fan, a filter screen, a wind guide plate, a hinge plate, a cover plate, a guide post, a pushing member, a second spring, a rack and pinion, and a pulling member. A plurality of fans are connected to the outer shell, and filter screens are connected to each fan. A plurality of wind guide plates are connected to the lower part of the outer shell. Hinge plates are connected to the left and right sides and the front and back sides of the lower part of the outer shell, and cover plates are rotatably connected to the hinge plates. A plurality of guide posts are connected to the inner bottom of the outer shell, and a pushing member is slidably connected between the guide posts. Second springs are connected between the guide posts and the pushing member. Rack and pinions are connected between the cover plates and the pushing member. A pulling member is connected to the middle of the multi-stage lifting platform, and the pulling member contacts the pushing member. When the multi-stage lifting platform moves upward, it will pull the pushing member through the pulling member, causing the pushing member to move upward and compress the second spring. When the pushing member moves upward, under the action of the rack and pinion, the cover plate rotates and opens away from the outer shell, exposing the fan to the outside. Then, air is blown through the fan, enabling the sprayed water-based fire extinguishing agent to be diffused, increasing the coverage range of the water-based fire extinguishing agent, and suppressing the fire in the distance.

[0011] Furthermore, it also includes a support mechanism for increasing the support of the outer shell. The support mechanism includes a mounting block, a support plate, a second connecting plate, and a hinge seat.

Hinge seats are slidably connected to the cover plates, and second connecting plates are rotatably connected between the support plates and the hinge seats on the cover plates on the same side. When the cover plate rotates and opens, the support plate is driven to rotate through the cooperation of the hinge seat and the second connecting plate, causing the support plate to rotate and approach the bottom, increasing the support stability of the outer shell.

[0012] Furthermore, it also includes a marking mechanism for marking the remaining amount of the water-based fire extinguishing agent inside the water tank. The marking mechanism includes a marking frame and a floating rod. The marking frame is connected to the upper sides of the left and right parts of the outer shell, and the floating rod is slidably connected to the marking frame. The bottom of the floating rod passes through the outer shell and penetrates into the water tank. The floating rod is subjected to the buoyancy of the water-based fire extinguishing agent inside the water tank and slides on the marking frame. When the water-based fire extinguishing agent decreases, the floating rod gradually moves downward. When it moves down to the critical value of the marking frame, it indicates that the remaining amount of the water-based fire extinguishing agent inside the water tank is insufficient and needs to be added.

[0013] Furthermore, a feeding pipe is provided at the upper part of the outer shell, and the bottom of the feeding pipe passes through the outer shell and is connected to the liquid inlet of the water tank.

[0036] As Figures 1 - 5 shown, the conveying mechanism 6 includes a mounting seat 61, a recovery disc 62, a volute spring 63, a conveying pipe 64, a pressing member 65, a rotating connector 66, a water pump 67 and a water tank 68. The mounting seat 61 is connected to the inner side of the lower left part of the housing 1, the recovery disc 62 is rotatably connected to the mounting seat 61, a volute spring 63 is connected between the front part of the recovery disc 62 and the mounting seat 61, the pressing member 65 is connected to the lower part of the multi-stage lifting platform 2, the rotating connector 66 is connected to the rear side of the recovery disc 62, a conveying pipe 64 is connected between the rotating connector 66 and the flow dividing cylinder 3, the conveying pipe 64 is wound around the recovery disc 62, the conveying pipe 64 passes through the pressing member 65, and the pressing member 65 is in pressing fit with the conveying pipe 64. The water tank 68 is placed on the inner side of the rear part of the housing 1, a feeding pipe is arranged on the upper part of the housing 1, the bottom of the feeding pipe passes through the housing 1 and is connected to the liquid inlet of the water tank 68 to facilitate adding water-based fire extinguishing agent into the water tank 68. The water pump 67 is connected to the bottom of the housing 1, the water inlet end of the water pump 67 is connected to the water tank 68 through a hose, and the water outlet end of the water pump 67 is connected to the rotating connector 66 through a conduit.

[0037] As Figure 1 、 Figure 2 and Figure 6 shown, the swinging mechanism 7 includes a swinging ring 71, a guiding ring 72, a first spring 73, a first connecting plate 74, a pressing-down member 75 and an electric push rod 76. The swinging rings 71 are all connected to the spray heads 4, ten guiding rings 72 are connected to the flow dividing cylinder 3, the swinging rings 71 are all slidably connected to the adjacent guiding rings 72, the first springs 73 are connected between the upper and lower parts of the swinging rings 71 and the adjacent guiding rings 72 respectively, the electric push rod 76 is connected to the top of the flow dividing cylinder 3, the pressing-down member 75 is connected to the telescopic end of the electric push rod 76, the lower part of the pressing-down member 75 passes through the flow dividing cylinder 3 and is slidably connected to the flow dividing cylinder 3, and the first connecting plates 74 are rotatably connected between the swinging rings 71 and the pressing-down member 75.

[0038] When the present invention is in use, first place the outer shell 1 in an area where fire prevention is required, such as a factory or a warehouse. When a fire occurs, the carbon dioxide sensor 5 detects that the carbon dioxide concentration in the air exceeds the standard and activates the multi-stage lifting platform 2. The multi-stage lifting platform 2 controls the diversion cylinder 3 to move upward out of the outer shell 1. After the multi-stage lifting platform 2 controls the diversion cylinder 3 and the spray head 4 to reach the proper positions, start the water pump 67. The water pump 67 introduces the water-based fire extinguishing agent in the water tank 68 into the delivery pipe 64, then into the diversion cylinder 3 through the delivery pipe 64, and then is diverted into the spray head 4 through the diversion cylinder 3 and sprayed out by the spray head 4 for fire extinguishing operations. When the multi-stage lifting platform 2 rises, the diversion cylinder 3 will pull the delivery pipe 64, so that the recovery disc 62 rotates adaptively to extend the delivery pipe 64. When the multi-stage lifting platform 2 descends, the scroll spring 63 rebounds to make the recovery disc 62 rotate to wind up the delivery pipe 64, adapting to the lifting height of the multi-stage lifting platform 2. When the recovery disc 62 rotates, the rotating connector 66 can keep the water outlet end of the water pump 67 always connected, avoiding affecting the export of the water-based fire extinguishing agent in the water tank 68 by the water pump 67. While the spray head 4 is performing the spraying operation, the telescopic end of the electric push rod 76 moves up and down to control the pressing member 75 to move up and down. The up and down movement of the pressing member 75 controls the sliding of the swing ring 71 through the first connecting plate 74. The swing ring 71 moves up and down in the guide ring 72 to drive the spray head 4 to move up and down. The up and down movement of the spray head 4 increases the spraying range of the water-based fire extinguishing agent. After the fire is extinguished, the multi-stage lifting platform 2 controls the diversion cylinder 3 and the spray head 4 to move downward and reset back into the outer shell 1 for storage. Through the above-mentioned carbon dioxide sensor 5 to monitor the fire situation, control the multi-stage lifting platform 2 to perform lifting operations, drive the diversion cylinder 3 and the spray head 4 to move, and have the water pump 67 pump the water-based fire extinguishing agent and spray it out by the spray head 4, it can achieve the effect of being set in the fire prevention area and automatically spraying water-based fire extinguishing agent for fire extinguishing when a fire occurs, improving the fire extinguishing safety.

[0039] As Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 shown in the figure, it further includes a shaking mechanism 8. The shaking mechanism 8 includes a guide rod 81, a shaking plate 82, a servo motor 83 and a cam 84. Three guide rods 81 are connected to the inner bottom of the outer shell 1. The shaking plate 82 is slidably connected between the guide rods 81. The water tank 68 can be placed on the shaking plate 82. The servo motor 83 is connected to the lower right side inside the outer shell 1. A cam 84 is connected to the output shaft of the servo motor 83. The cam 84 is in pressing fit with the shaking plate 82.

[0040] By using the shaking mechanism 8 of the present invention, the water tank 68 can be shaken to loosen the water base in the water-based fire extinguishing agent. Before the water-based fire extinguishing agent is sprayed, the output shaft of the servo motor 83 rotates to drive the cam 84 to rotate. The protruding part of the rotating cam 84 repeatedly presses the shaking plate 82, causing the shaking plate 82 to drive the water tank 68 to move up and down. The up and down movement of the water tank 68 causes the water-based fire extinguishing agent inside to shake, loosening the water base of the water-based fire extinguishing agent and improving the spraying effect. By controlling the rotation of the cam 84 through the output shaft of the above-mentioned servo motor 83, the cam 84 presses the shaking plate 82, and the shaking of the shaking plate 82 drives the water tank 68 to shake, which can shake the water tank 68 and loosen the water base in the water-based fire extinguishing agent to improve the spraying effect.

[0041] As Figure 1 , Figure 2 and Figure 9 shown, it further includes a diffusion mechanism 9. The diffusion mechanism 9 includes a fan 91, a filter screen 92, a wind guide plate 93, a hinge plate 94, a cover plate 95, a guide post 96, a pushing member 97, a second spring 98, a gear rack 99 and a pulling member 910. Four fans 91 are connected to the housing 1, filter screens 92 are connected to the fans 91, four wind guide plates 93 are connected to the lower part of the housing 1, hinge plates 94 are connected to the left and right sides and the front and rear sides of the lower part of the housing 1, cover plates 95 are rotatably connected to the hinge plates 94, four guide posts 96 are connected to the inner bottom of the housing 1, a pushing member 97 is slidably connected between the guide posts 96, second springs 98 are connected between the guide posts 96 and the pushing member 97, gear racks 99 are connected between the cover plates 95 and the pushing member 97, a pulling member 910 is connected to the middle of the multi-stage lifting platform 2, and the pulling member 910 contacts the pushing member 97.

[0042] By using the diffusion mechanism 9 of the present invention, the spraying area of the water-based fire extinguishing agent can be increased. When the multi-stage lifting platform 2 moves upward, it will pull the pushing member 97 through the pulling member 910, causing the pushing member 97 to move upward and compress the second spring 98. When the pushing member 97 moves upward, under the action of the gear rack 99, the cover plate 95 rotates and opens away from the housing 1, exposing the fan 91 to the outside. Then, air is blown through the fan 91, enabling the sprayed water-based fire extinguishing agent to diffuse, increasing the coverage range of the water-based fire extinguishing agent, and suppressing the fire in the distance. When the multi-stage lifting platform 2 descends, the second spring 98 rebounds, causing the pushing member 97 to reset. When the pushing member 97 resets, under the action of the gear rack 99, the cover plate 95 flips and resets, re-fitting with the housing 1 to cover the fan 91 and the wind guide plate 93 for daily dust prevention operations. By blowing air through the above-mentioned fan 91 to blow the sprayed water-based fire extinguishing agent, the effect of increasing the spraying area of the water-based fire extinguishing agent and increasing the coverage range of the water-based fire extinguishing agent can be achieved.

[0043] As Figure 1 , Figure 2 , Figure 10and Figure 11 As shown in Figure 11 , it further includes a support mechanism 10, which includes a mounting block 101, a support plate 102, a second connecting plate 103 and a hinge seat 104. Eight mounting blocks 101 are connected to the lower part of the housing 1. A support plate 102 is rotatably connected between the mounting blocks 101 on the same side. Hinge seats 104 are slidably connected to the cover plates 95. A second connecting plate 103 is rotatably connected between the support plate 102 and the hinge seats 104 on the cover plates 95 on the same side.

[0044] When using the support mechanism 10 of the present invention, the supportability of the housing 1 can be increased. When the cover plate 95 is rotated and opened, the support plate 102 is driven to rotate through the cooperation of the hinge seat 104 and the second connecting plate 103, so that the support plate 102 rotates close to the bottom, increasing the support stability of the housing 1. By rotating and opening the cover plate 95 to control the rotation and deployment of the support plate 102, the support area of the housing 1 can be expanded, and the support stability of the housing 1 can be improved.

[0045] As Figure 2 、 Figure 12 and Figure 13 As shown in Figure 2 , Figure 12 and Figure 13 , it further includes a marking mechanism 11, which includes a marking frame 111 and a floating rod 112. The marking frame 111 is connected to the upper sides of the left and right parts of the housing 1. The floating rod 112 is slidably connected to the marking frame 111, and the bottom of the floating rod 112 passes through the housing 1 and penetrates into the water tank 68.

[0046] When using the marking mechanism 11 of the present invention, the remaining amount of the aqueous fire extinguishing agent inside the water tank 68 can be marked. The floating rod 112 is subjected to the buoyancy of the aqueous fire extinguishing agent inside the water tank 68 and slides on the marking frame 111. When the aqueous fire extinguishing agent decreases, the floating rod 112 gradually moves downward. When it moves down to the critical value of the marking frame 111, it indicates that the remaining amount of the aqueous fire extinguishing agent inside the water tank 68 is insufficient and needs to be added. By the above operation that the floating rod 112 is subjected to the buoyancy of the aqueous fire extinguishing agent inside the water tank 68 and slides on the marking frame 111, the remaining amount of the aqueous fire extinguishing agent inside the water tank 68 can be marked, facilitating the timely addition of the aqueous fire extinguishing agent inside the water tank 68.

[0047] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
