Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting and extinguishing, in particular to a self-extinguishing fire extinguishing device. Background Art

[0002] Fire extinguishers are usually placed in places where fires may occur in public places. Common portable fire extinguishers weigh several kilograms and are light and easy to carry and use. The operation method is simple. Pull out the safety pin and press the pressure handle of the bottle valve to spray the fire extinguishing agent. The problem is that fire extinguishers are placed in fixed positions in the venue. When a fire occurs, someone must take the fire extinguisher to the fire scene and aim it at the fire source to extinguish the fire. In most fires, no one is on the scene. Failure to transport the fire extinguisher to the scene to extinguish the fire in the early stage of the fire will cause the fire to spread and even cause greater property losses.

[0003] The utility model patent with application number: CN201921635624.5 and publication number: CN210963668U (hereinafter referred to as "prior art 1") discloses a self-propelled pressurized fire extinguishing device.

The advantage of such a setting is that First, by installing multiple fire extinguishers 102 on the remote control car 101 at one time, the problem of investing a lot of manpower, material resources, time and effort in fire extinguishing is solved, thereby ensuring the life safety of fire extinguishers; second, by moving the remote control car 101, it is possible to quickly reach the fire scene to control the spread of fire, and remote control operation can solve the problem that the fire extinguishing device cannot extinguish fires at close range in many scenarios; third, the mobile device that can quickly replace and install the fire extinguisher 102 can realize the rapid replacement of the fire extinguisher 102 of various fire extinguishing agents, thereby avoiding the traditional water fire extinguishing method that causes damage to household items.

[0032] In some embodiments, an installation box 112 is provided on the electric trolley, and an extrusion device is provided on the installation box 112. One end of the delivery pipe 103 extends into the installation box 112, and the other end extends out of the installation box 112 and is connected to the X-axis rotation assembly 106; the X-axis rotation assembly 106 is fixedly connected to the installation box 112; the bottom of the fire extinguisher 102 is provided in the installation box 112, and the top extends out of the installation box 112 and contacts with the extrusion device.

After the fire extinguisher 102 passes through the through holes, it is exposed to the outside of the installation box 112, and the installation box 112 can protect the fire extinguisher 102 and the delivery pipe 103.

[0033] In some embodiments, the X-axis rotation assembly 106 includes a first annular rack 113, a first mounting ring 114 is rotatably provided on the first annular rack 113, a first motor 115 is provided on the first mounting ring 114, a first gear 116 is fixedly provided on the output shaft of the first motor 115, and the first gear 116 is meshed with the first annular rack 113; the first curved pipe 109 passes through the first mounting ring 114 and is fixedly connected to the first mounting ring 114 and rotatably cooperates with the first annular rack 113, and the conveying pipe 103 is fixedly connected to the first annular rack 113 is fixedly connected. In actual use, the staff controls the first motor 115 to rotate. Since the first annular rack 113 is fixed on the mounting box 112, when the first motor 115 rotates, it drives the first mounting ring 114 to rotate on the first annular rack 113, thereby driving the first elbow 109 to rotate 360° along the X-axis direction, thereby adjusting the spraying angle of the fire gun 105. In this process, the inner surfaces of the first elbow 109, the delivery pipe 103, and the first annular rack 113 form a delivery channel for the fire extinguishing medium.

[0034] In some embodiments, the Y-axis rotation assembly 107 includes a second annular rack 117, a second mounting ring 118 is rotatably provided on the second annular rack 117, a second motor 119 is provided on the second mounting ring 118, a second gear 120 is fixedly provided on the output shaft of the second motor 119, and the second gear 120 is meshed with the second annular rack 117; one end of the second curved pipe 110 passes through the second mounting ring 118 and is fixedly connected to the second mounting ring 118 and rotatably cooperates with the second annular rack 117, and the first curved pipe 109 is fixedly connected to the second annular rack 117 is fixedly connected. In actual use, the staff controls the second motor 119 to rotate. Since the second annular rack 117 is fixed on the first elbow 109, when the second motor 119 rotates, it drives the second mounting ring 118 to rotate on the second annular rack 117, and then drives the second elbow 110 to rotate 360° along the Y-axis direction, so as to adjust the spraying angle of the fire gun 105. In this process, the inner surfaces of the first elbow 109, the second elbow 110 and the second annular rack 117 form a conveying channel for the fire extinguishing medium.

[0035] In some embodiments, a connecting pipe 121 is provided at one end of the delivery pipe 103 away from the fire gun 105. The connecting pipe 121 has a plurality of connecting holes 122. The number of the connecting holes 122 corresponds to the number of the one-way valves 108. The one-way valves 108 are detachably connected to the connecting holes 122. The purpose of providing the connecting pipe 121 is to facilitate the installation of the one-way valves 108 and to facilitate the staff to organize the lines.

[0036] In some embodiments, the mounting frame 123 is hinged to the mounting box 112 via a hinge 125 . The hinge 125 can make the rotation between the mounting frame 123 and the mounting box 112 smoother.

[0037] In some embodiments, the camera 111 is connected to the fire gun 105 via a connector 126 . Providing the connector 126 can make the connection between the camera 111 and the fire gun 105 more stable.

The number of telescopic components 124 corresponds to the number of fire extinguishers 102. There is one telescopic component 124 corresponding to the top of the push switch of each fire extinguisher 102. In actual use, the mounting frame 123 is used to install the telescopic component 124. The purpose of hinged connection between the mounting frame 123 and the mounting box 112 is to facilitate the replacement of the fire extinguisher 102 and prevent the telescopic component 124 from interfering with the fire extinguisher 102 when the fire extinguisher 102 is replaced.

[0040] In some embodiments, the telescopic component 124 is an electric telescopic component, a pneumatic telescopic component or a hydraulic telescopic component. As an implementation mode, in this embodiment, the telescopic component 124 is specifically an electric push rod. During actual use, the staff drives the electric push rod to extend, and the active end of the electric push rod extends to press the push switch on the fire extinguisher 102. The fire extinguisher 102 sprays the fire extinguishing medium through the one-way valve 108 into the delivery pipe 103.
