Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a fire fighting hose belt used for forest fire fighting. Background Art

[0002] Forest fire is the most dangerous enemy of forests and the most terrible disaster in forestry. It will bring the most harmful and devastating consequences to forests. Forest fire not only burns large tracts of forests and harms animals in the forest, but also reduces the reproductive capacity of forests, causes soil impoverishment and destroys forest water conservation, and even causes the ecological environment to lose balance. Due to the complex terrain, steep slopes and strong winds in forests, these factors make it difficult to control the fire. The relevant fire-fighting equipment is also difficult to effectively extinguish forest fires due to inconvenient transportation and difficulty in obtaining water. Firebreaks can only be set up and the fire can be extinguished. Therefore, forest fire fighting has become a problem in firefighting and rescue. Existing aircraft firefighting is also limited by the problem of transporting water resources. Not only is the transportation distance long, but the water absorption time is also long each time, which makes it impossible to effectively and timely extinguish the fire source. Summary of the invention

[0003] The purpose of the present invention is: to solve the problems existing in the above-mentioned background technology, and to provide a fire-fighting pipe belt for forest fire fighting, in which the power supply and water supply pipelines are integrated through a double-layer water hose, and the pipe belt is directly connected to the water source and the fire-fighting point by hanging an unmanned aerial vehicle, which can reduce the water transportation process and the back-and-forth movement of the aircraft. The power supply in the pipe belt can directly provide power to the unmanned aerial vehicle, so that it can directly power the flight and hang the pipe belt for fire fighting, and can quickly spray water to the fire-fighting point regardless of the terrain.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fire hose for forest fire fighting, comprising a hose main body, wherein the hose main body is sequentially provided with an outer protective layer, a positive electrode braided layer, a negative electrode braided layer, an insulating layer and a flexible water hose from the outside to the inside, wherein the outer protective layer is made of a flexible fire-retardant material, an insulating layer is bonded inside the outer protective layer, a positive electrode braided layer is bonded inside the insulating layer, an insulating layer is bonded inside the positive electrode braided layer, a negative electrode braided layer is bonded inside the insulating layer, an insulating layer is also bonded inside the negative electrode braided layer, and a flexible water hose is bonded inside the insulating layer. The positive electrode braided layer and the negative electrode braided layer are woven into a mesh with conductive metal wires, and the inner and outer surfaces of the two are covered with an insulating layer. Quick-release connectors are also provided at both ends of the tube belt body, which are a male head and a female head respectively, and the two can be rotatably connected. The quick-release connector includes a water channel, a negative electrode channel, a positive electrode channel and a shell arranged from the inside to the outside, wherein the water channel is connected with the flexible water belt, the positive electrode is connected with the positive electrode braided layer, the negative electrode channel is connected with the negative electrode braided layer, and the male head and the female head are quickly connected and disassembled by spiral claws arranged on the shell.

[0005] Further, a perforation for hanging and towing is also provided in the middle of the housing, and a power plug is provided outside the housing. The positive and negative poles of the power plug are respectively connected to the positive channel and the negative channel inside the housing through wires, facilitating power supply to the drone through the power plug. The perforation facilitates hanging the quick-release connector under the drone.

[0006] Further, the positive channel or the negative channel is composed of an insulating fixing seat, a circular conductor, and multiple groups of contacts. The circular conductor is circularly installed at the center of the insulating fixing seat, and the contacts are circumferentially distributed on the circular conductor and fixedly connected to the circular conductor, and are connected to the positive braided layer or the negative braided layer through the contacts.

[0007] Further, the insulating fixing seat is snap-fitted inside the housing, and two insulating fixing seats, namely an inner ring and an outer ring, are respectively used to install the circular conductors and contacts of the positive and negative poles.

[0008] Further, there are eight contacts, and the contacts on the positive channel and the negative channel are arranged at intervals and do not overlap.

[0009] Further, the outer protective layer is made of flame-retardant rubber.

[0010] The beneficial effects of the present invention are as follows: 1) In the present invention, multiple groups can be spliced and installed into an integral body. Through the perforation on the quick-release connector, the drone can be hung and powered. Through multiple drones, the entire pipeline can be hung and transported between the water source and the fire extinguishing point. Through an external water pump, water is pumped towards the fire extinguishing point for extinguishing. During the process, the power drive of the pipeline is adapted to the DC power supply of the drone. After being converted by an external power converter, the alternating current is connected to the power plug to provide power supply, providing a driving power supply for the directly connected drone. It can reduce the transportation of water and drones and reduce energy loss. It can quickly extinguish the fire at the fire site regardless of the terrain, and has a simple structure and is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
