Description

Technical Field

[0001] This utility model belongs to the technical field of foam fire extinguishing devices, and in particular relates to a mobile clean gas foam fire extinguishing device. Background Technology

[0002] Compressed air foam fire extinguishing systems are a type of efficient, low-consumption, multi-purpose, lightweight, and environmentally friendly fire extinguishing system. Compared with traditional negative pressure foam fire extinguishing technology, compressed air foam generated by positive pressure has the characteristics of finer and more uniform foam structure and higher foam stability. In addition, compressed air foam has the characteristics of low frictional resistance and controllable foaming ratio. The appropriate foaming ratio and foam state can be adjusted according to different protected objects, which can effectively extinguish solid and liquid fires and greatly improve fire extinguishing efficiency.

[0003] A search revealed Chinese patent application number 202321347646.8, which discloses a mobile compressed air foam fire extinguishing device. The device includes a base and a foam fire extinguishing tank. A push rod is fixedly connected to the outer wall of the base, and a control panel is installed on the outer wall of the push rod. Two symmetrical blocks are fixedly connected to the upper surface of the base. A bidirectional screw is fixedly connected to the outer wall of each block via a bearing. The other end of the bidirectional screw passes through the inner wall of the block and is rotatably connected to a rotating handle. This invention effectively adjusts the height of the foam fire extinguishing tank according to actual conditions, making it convenient for users of different heights to use the device and avoiding safety hazards during fire extinguishing. It allows for easy movement of the foam fire extinguishing tank during use and can be fixed in place during fire extinguishing to prevent slippage. This improves the effectiveness and practicality of the mobile compressed air foam fire extinguishing device. However, it suffers from the following drawbacks: complex structure and high manufacturing cost. Utility Model Content

[0004] This invention provides a mobile clean gas foam fire extinguishing device, which aims to solve the problems of complex equipment structure and high manufacturing cost in the prior art.

[0005] This utility model is implemented as follows: a mobile clean gas foam fire extinguishing device includes a base plate, a foam fire extinguishing tank, and a controller. A support rod is fixedly connected to the lower surface of the base plate, and a base is provided below the support rod. An electro-hydraulic rod is hinged to the lower surface of the base plate, and the electro-hydraulic rods are symmetrically distributed along the vertical center line of the base plate. A connecting plate is fixedly connected to the telescopic end of the electro-hydraulic rod, and a device shaft is rotatably connected to the outer wall of the connecting plate. Tires are fixedly connected to both ends of the device shaft, and a movable plate is rotatably connected to the outer wall of the device shaft. A fixed plate is fixedly connected to the lower surface of the base plate, and the fixed plate and the movable plate are rotatably hinged. The electro-hydraulic rod is electrically connected to the controller.

[0006] Preferably, a handrail is fixedly connected to the upper surface of the base plate.

[0007] Preferably, the outer wall of the handrail is provided with anti-slip texture.

[0008] Preferably, a damper is provided between the support rod and the base, and a spring is sleeved on the outer wall of the damper.

[0009] Preferably, an anti-slip pad is fixedly connected to the lower surface of the base.

[0010] Compared with the prior art, the embodiments of this application have the following main advantages:

[0011] When the equipment needs to be moved, the operator uses the controller to extend the telescopic end of the electro-hydraulic rod, allowing the movable plate to rotate on the outer wall of the fixed plate. This reduces the angle between the vertical center line of the movable plate and the vertical center line of the fixed plate, causing the tire to rotate downwards and lift the base plate. This facilitates the movement of the equipment. When the equipment reaches the designated location, the operator retracts the telescopic end of the electro-hydraulic rod, increasing the angle between the vertical center line of the movable plate and the vertical center line of the fixed plate. This causes the movable plate to rotate upwards, raising the tire and allowing the support rod and base to support the base plate. This improves the stability of the equipment and prevents displacement during operation. Attached Figure Description

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model embodiment provides a mobile clean gas foam fire extinguishing device, such as... Figure 1-4 As shown, the device includes a base plate 1, a foam fire extinguishing tank 2, and a controller 3. A support rod 5 is fixedly connected to the lower surface of the base plate 1, and a base 6 is provided below the support rod 5. An electro-hydraulic rod 7 is hinged to the lower surface of the base plate 1, and the electro-hydraulic rod 7 is symmetrically distributed along the vertical center line of the base plate 1. A connecting plate 8 is fixedly connected to the telescopic end of the electro-hydraulic rod 7, and an equipment shaft 9 is rotatably connected to the outer wall of the connecting plate 8. Tires 10 are fixedly connected to both ends of the equipment shaft 9, and a movable plate 11 is rotatably connected to the outer wall of the equipment shaft 9. A fixed plate 12 is fixedly connected to the lower surface of the base plate 1, and the fixed plate 12 and the movable plate 11 are rotatably hinged. The electro-hydraulic rod 7 and the controller 3 are electrically connected.

[0020] It should be noted that, due to the complex structure and high manufacturing cost of existing equipment, this solution addresses this issue by having personnel operate the controller 3 when the equipment needs to be moved. The controller 3 controls the extension of the telescopic end of the electro-hydraulic rod 7, allowing the movable plate 11 to rotate on the outer wall of the fixed plate 12. This reduces the angle between the vertical center line of the movable plate 11 and the vertical center line of the fixed plate 12, causing the tire 10 to rotate downwards and lift the base plate 1. The tire 10 facilitates the movement of the equipment. When the equipment reaches the designated location, the telescopic end of the electro-hydraulic rod 7 retracts, increasing the angle between the vertical center line of the movable plate 11 and the vertical center line of the fixed plate 12. This causes the movable plate 11 to rotate upwards, raising the tire 10 and allowing the support rod 5 and the base 6 to support the base plate 1. This improves the stability of the equipment placement and prevents displacement during operation.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a handrail 4 is fixedly connected to the upper surface of the base plate 1.

[0022] In this embodiment, the handrail 4 facilitates the operation of the equipment by personnel.

[0023] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the outer wall of the handrail 4 is provided with anti-slip texture.

[0024] In this embodiment, the anti-slip texture increases the friction of the outer wall of the handrail 4, preventing slippage when people operate the handrail 4.

[0025] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a damper 13 is provided between the support rod 5 and the base 6, and a spring is sleeved on the outer wall of the damper 13.

[0026] In this embodiment, the device will generate vibrations when it is working. The damper 13 and the spring absorb and weaken the vibrations of the device, reduce the impact of the vibrations on the surrounding environment, and further improve the stability of the device when it is working.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 As shown, an anti-slip pad is fixedly connected to the lower surface of the base 6.

[0028] In this embodiment, the anti-slip pad increases the friction on the lower surface of the base 6, preventing the base 6 from slipping on the ground.
