Description

Technical Field

[0001] This utility model relates to the field of fire drainage technology, and in particular to an emergency drainage device for fire-fighting equipment. Background Technology

[0002] In recent years, due to unscientific drainage network layout, aging pipes, and low drainage standards in some Chinese cities, urban flooding and waterlogging disasters are highly likely to occur when heavy or continuous rainfall exceeds the city's drainage capacity and there is no emergency drainage system.

[0003] Chinese Patent CN222025230U discloses an emergency drainage device for fire-fighting equipment, including an emergency vehicle. The emergency vehicle has an anti-clogging mechanism at its front, a winding mechanism inside, and a positioning mechanism at its bottom. The anti-clogging mechanism consists of a set of side panels, each with a support rod fixedly connected to its inner side. A water inlet head is fixedly connected between the support rods. The surface of the water inlet head has multiple water inlet holes evenly distributed, and the surface of the filter screen has multiple winding spikes. This technical solution, through its anti-clogging mechanism, allows the set of side panels and the internal water inlet head to be submerged in accumulated water. This not only ensures that the water intake is significantly greater than the direct suction of the water pipe, but also that the multiple filter screens between the side panels filter out debris and other contaminants from the water pipe, preventing them from being sucked in and causing blockages or even reducing the lifespan of the water pump. The winding spikes on the filter screen surface can wrap plastic bags, hair, and other debris around the outside for easy disposal.

[0004] However, the above technical solutions have the following shortcomings: after urban flooding, roads will deteriorate due to floating debris, making it difficult for the wheels and hydraulic cylinders on the emergency vehicle to travel on poor roads. Furthermore, when traveling on bumpy roads, the vibrations on the emergency vehicle will affect the service life of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an emergency drainage device for fire-fighting equipment that uses a hydraulic cylinder to drive multiple wheels to lift and lower, thereby adjusting the distance between the chassis and the ground, and a buffer component to absorb and reduce vibrations during the movement of the device.

[0006] The technical solution of this utility model is an emergency drainage device for fire-fighting equipment, comprising: a chassis with a generator box and a drainage pump mounted on its top; two sets of movable components mounted on the chassis, each movable component including a mounting frame, multiple rotating seats mounted on the mounting frame, two buffer components mounted opposite each other on the mounting frame, two adjusting rods rotatably mounted opposite each other on the mounting frame, bearings a and b mounted on each of the two adjusting rods, a rotating disk mounted on each of the two bearings a, and a fixed disk mounted on each of the two bearings b; the two buffer components are connected to the two adjusting rods one-to-one, and each of the two fixed disks is equipped with a wheel; and multiple hydraulic cylinders are rotatably mounted on the chassis, with the output ends of the multiple hydraulic cylinders rotatably connected to the multiple rotating seats one-to-one.

[0007] Preferably, the chassis has two pairs of inclined channels, and the two pairs of rotating disks are distributed one-to-one at the two pairs of inclined channels.

[0008] Preferably, a buffer pad is provided at the inclined channel.

[0009] Preferably, the buffer assembly includes a buffer cylinder mounted on a mounting frame, a pusher mounted slidably on the buffer cylinder, a spring mounted on the buffer cylinder and the pusher, a clamping frame rotatably mounted on the pusher, and two clamping blocks rotatably mounted on the clamping frame.

[0010] Preferably, both clamping blocks are provided with elastic pads.

[0011] Preferably, each of the multiple bearings a and bearing b is provided with a sealing disc.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] When in use, the hydraulic cylinder pulls the mounting frame to move according to the water depth on the moving road. The rotating plate rotates and contacts the chassis. The rotating plate and the hydraulic cylinder work together to pull the mounting frame up, raising the height of the wheels set on the fixed plate. This improves the versatility of the device. When the drainage device moves on bumpy roads, the wheels are tubeless tires. As the fixed plate is tilted by the adjusting rod, the width of the wheels can ignore the rotation range of the adjusting rod. Furthermore, the buffer component absorbs the vibration transmitted by the adjusting rod, thereby reducing the vibration amplitude during the movement of the drainage device and extending its service life.

Detailed Implementation

[0018] Example 1

[0019] like Figures 1-3 As shown in the figure, this embodiment proposes an emergency drainage device for fire-fighting equipment, including a chassis 1, a moving assembly 4, and a hydraulic cylinder 5. A generator box 2 and a drainage pump 3 are mounted on the top of the chassis 1. The generator box 2 contains a diesel generator, a fuel tank, a battery, and a control device. The diesel generator generates electricity to power the control device and the drainage pump 3. A hook is also mounted on the chassis 1, allowing a vehicle to pull the chassis 1 using the hook and rope to move the drainage device to a suitable location. Two sets of the moving assembly 4 are mounted on the chassis 1. The moving assembly 4 includes a mounting frame 41, multiple rotating seats 42 mounted on the mounting frame 41, and... The mounting frame 41 has two buffer components 43 arranged opposite to each other, two adjusting rods 44 rotatably arranged opposite to each other on the mounting frame 41, a bearing a 45 and a bearing b on each of the two adjusting rods 44, a rotating disk 46 on each of the two bearings a 45, and a fixed disk 47 on each of the two bearings b; the two buffer components 43 are connected to the two adjusting rods 44 one by one, and each of the two fixed disks 47 has a wheel 6; multiple hydraulic cylinders 5 are rotatably arranged opposite to each other on the chassis 1, and the output ends of the multiple hydraulic cylinders 5 are rotatably connected to multiple rotating seats 42 one by one.

[0020] In this embodiment, the hydraulic cylinder 5 pulls the mounting frame 41 to move according to the water depth on the moving road. The rotating disk 46 rotates and contacts the chassis 1. The rotating disk 46 and the hydraulic cylinder 5 work together to pull the mounting frame 41 up. The height of the wheel 6 set on the fixed disk 47 increases, improving the versatility of the device. When the drainage device moves on bumpy roads, the wheels are tubeless tires. During the tilting process of the fixed disk 47 driven by the adjusting rod 44, the width of the wheels can ignore the rotation range of the adjusting rod 44. In addition, the buffer component will absorb the vibration transmitted by the adjusting rod 44, thereby reducing the vibration amplitude during the movement of the drainage device and improving the service life of the drainage device.

[0021] Example 2

[0022] like Figure 1 and Figure 2As shown, this embodiment of the emergency drainage device for fire-fighting equipment, compared to Embodiment 1, has two pairs of inclined channels 11 on the chassis 1, and two pairs of rotating disks 46 are correspondingly distributed at the two pairs of inclined channels 11. Buffer pads are provided at the inclined channels 11. Sealing discs are provided on multiple bearings a45 and bearing b.

[0023] When the rotating disk 46 in this embodiment is vibrated and moves upward, it will move upward for a certain distance before contacting the top of the inclined channel 11 at the chassis 1. An elastic pad is provided at the top of the inclined channel 11 to absorb the vibration generated when the rotating disk 46 contacts the chassis 1. A sealing pad is provided on each of the multiple sealing disks. Lubricating oil is provided on the multiple sealing pads and sealing disks in a one-to-one correspondence with the multiple bearings a45 and bearings b. The sealing pads and sealing disks can prevent sewage from contaminating the bearings a45 and bearings b.

[0024] Example 3

[0025] like Figure 2 and Figure 3 As shown, the emergency drainage device for fire-fighting equipment proposed in this embodiment, compared with the first embodiment, includes a buffer assembly 43 comprising a buffer cylinder 431 mounted on a mounting frame 41, a push frame 433 slidably mounted on the buffer cylinder 431, a spring 432 mounted on the buffer cylinder 431 and the push frame 433, a clamping frame 434 rotatably mounted on the push frame 433, and two clamping blocks 435 rotatably mounted on the clamping frame 434; both clamping blocks 435 are provided with elastic pads.

[0026] In this embodiment, two clamping blocks 435 clamp the adjusting rod 44 from both ends. The two clamping blocks 435 are fixed by bolts and nuts. The two clamping blocks 435 are in contact with the adjusting rod 44 through elastic pads. The adjusting rod 44 drives the push frame 433 to move through the clamping blocks 435. The push frame 433 pushes the spring 432 to compress, thereby absorbing the vibration generated during the movement of the device.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
