Technical Field

The invention belongs to an air suction pipeline, and particularly relates to a hose for sucking fluid.

Background

Underground engineering such as underground garages, subways, tunnels, mines, buildings or operation places with closed spaces and the like have strict requirements on ventilation and water communication, fresh air needs to be conveyed into the underground engineering, smoke dust and accumulated water in the underground engineering can be quickly and conveniently discharged under special conditions such as disasters like fire disasters and water permeability, and the underground engineering has important significance on rescuing lives and properties and subsequent rescue work. At present, the air suction pipelines applied to the market can be mainly divided into fixed installation type ventilation pipes and telescopic ventilation pipes. The fixed installation type ventilation pipe is mainly used in fixed places such as civil engineering, buildings, basements, factory buildings, kitchens and the like which have enough space and need ventilation for a long time; the telescopic ventilation pipe is mainly used in occasions with limited space or emergency rescue requirements, such as tunnels, ship bodies, fire-fighting rescue, municipal pipeline dredging, deep well operation and the like.

The existing telescopic ventilation pipe is mainly manufactured by adopting a mode of supporting a soft pipe body and a rigid framework, the soft pipe body can be stretched to be used for air draft during normal use, and the soft pipe body can be compressed in the axial direction to reduce the size and is convenient to store and store after being used up. However, the compressed pipeline still has a large volume and is difficult to transport and store, and if the pipeline is used as a fire-fighting emergency rescue vehicle, the length of the pipeline must meet certain requirements, and the storage space of the fire-fighting emergency rescue vehicle is very limited and cannot meet the storage requirement of the pipeline.

Disclosure of Invention

The invention aims to provide a hose for sucking fluid, which has a small volume after being stored and is suitable for being stored in a small space.

The technical scheme adopted for realizing the purpose of the invention is as follows:

the hose for sucking fluid provided by the invention comprises a hose body made of soft materials, wherein an upper arc elastic body and a lower arc elastic body which are distributed at intervals are fixed on the hose body along the hose body.

The elastic bodies in the upper row and the lower row are correspondingly arranged.

The correspondingly arranged elastic bodies are connected through flexible materials or through torsion springs or hinges.

The correspondingly arranged elastic bodies are steel wires which are connected in series through a plurality of torsion springs, and the correspondingly arranged steel wire elastic bodies are connected through the torsion springs.

The elastic body is made of one of a steel wire, a steel sheet and a serpentine spring or is made of a nonmetal elastic material.

And two ends of the pipe body are respectively provided with a joint made of flexible materials.

Elastic connecting parts which are axially connected are arranged between the elastic body and the joint and between the elastic body and the elastic body.

The elastic body or the elastic body and the elastic connecting part are fixed on the pipe body through a fixing buckle.

The elastomer is arranged in the joint.

The joints at the two ends of the pipe body are a male joint and a female joint which can be mutually sleeved.

Advantageous effects

1. The invention is characterized in that the upper and lower rows of arc-shaped elastic bodies which are distributed at intervals are fixed on the soft material pipe body, the pipe body between the two rows of elastic bodies can be bent and flattened, the structure ensures that the pipe body can be quickly stretched by the arc-shaped elastic bodies when being opened for use, meets the requirements of smoke dust, accumulated water and the like for suction in emergency rescue, and the pipe body can be flattened and wound into a disc-shaped body along with the elastic bodies when being stored, thereby reducing the volume to the maximum extent, being convenient for storing the pipe body as long as possible in a limited space, being very suitable for buildings, subways, civil air defense projects and fire emergency rescue vehicles with limited storage space, and having important significance for emergency and rescue dangerous disasters and guaranteeing the safety of lives and.

2. The connecting parts of the two elastic bodies which correspond to each other up and down are made of flexible materials, torsion springs or hinges, so that the elastic bodies are prevented from causing metal fatigue elastic failure and finally breaking as the whole elastic bodies when repeatedly pressed and deformed on the basis of enhancing the integrity of the elastic bodies, and the service life of the elastic bodies can be prolonged.

3. Elastic connecting parts which are axially connected are arranged between the elastic body and the joint and between the elastic body and the elastic body, so that the pipe body can be better prevented from twisting and contracting, and the smoothness of the pipe body is ensured.

The technical scheme of the invention is further explained by combining the attached drawings.
