Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting water supply equipment, in particular to a coupled water supply device. Background Art

[0002] When a fire occurs, the fire truck needs to immediately set off for the fire scene, arrive at the scene in the shortest time and start fire-fighting operations. After arriving at the fire scene, appropriate fire-fighting equipment should be selected according to the fire situation. Common fire-fighting strategies include direct fire-fighting (such as using a water gun to spray water on the fire source), indirect fire-fighting (such as extinguishing the fire by cutting off the fire source or the supply of combustibles), cooling fire-fighting (such as using water or other coolants to reduce the temperature of the fire scene), etc.; at the fire scene, the fire pump will start and pump water from the fire pool, fire water tank or municipal pipeline network, and transport it to the fire scene through the water supply network. Firefighters can connect the fire hose and fire hose through the terminal water intake device (such as a fire hydrant) to spray water at the fire source to extinguish the fire.

[0003] The fire trucks in current fire stations have insufficient water pressure for supplying water to super-high-rise buildings and long-distance water supply to forests and other places. Fire trucks and hand-lift pumps cannot provide sufficient water lift, resulting in poor super-high-rise or long-distance fire extinguishing effects. Some fire trucks with super-high-rise water supply functions are expensive and cannot be widely promoted and used. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a coupled water supply device, including a fire truck, a hand pump, and several coupled water supply device bodies, the water outlet of the fire truck and the hand pump are connected by a water pipe, the coupled water supply device body includes an outer bracket, an inner coupler, an outer coupler, an anti-throw device, and a water supply connecting pipe fitting, the upper and lower sides of the outer bracket are provided with cover plates, the inner coupler and the outer coupler are both located between the cover plates, a control panel is provided in front of the cover plate, the inner coupler and the outer coupler are connected through the anti-throw device, the inner coupler is connected with a water inlet connecting pipe, one end of the water supply connecting pipe fitting is connected with the water inlet connecting pipe, the outer coupler is provided with a water outlet connecting pipe, and a manual valve is provided on the cover plate.

[0006] Among them, multiple coupled water supply bodies can be used in series with each other according to specific on-site conditions to offset the problem of water pressure reduction caused by the large head of long-distance pipelines.

[0007] As an improvement, a water inlet pressure gauge is provided on the inner coupler, and an observation port is provided on the cover plate and above the water inlet pressure gauge.

[0008] As an improvement, a water pressure digital display is provided on the outer coupler, and the water pressure digital display is located above the cover plate.

[0010] The advantages of the present invention are that the fire trucks and hand pumps are connected in series with multiple coupled water supply bodies, replacing super-high-rise and high-pressure water supply fire trucks, reducing the construction cost of small fire stations, and realizing long-distance water supply, offsetting the problem of water pressure reduction caused by the large head of long-distance pipelines. For example, when extinguishing super-high-rise fires that cannot be reached by fire trucks or extinguishing fires inside forests, the terminal fire extinguishing water pipes are connected one by one to the coupled water supply body in sequence to achieve stable high-pressure water supply to the terminal.

[0017] Among them, multiple coupled water supply device bodies can be used in series with each other according to specific on-site conditions to offset the problem of water pressure reduction caused by the large head of long-distance pipelines. For example, when extinguishing fires in super-high-rise buildings or inside forests that fire trucks cannot reach, the terminal fire-fighting water pipes can be connected to the coupled water supply device bodies one by one in sequence to achieve stable high-pressure water supply to the terminal.

[0020] The water supply connecting pipe is provided with an automatic pressure relief valve, which automatically relieves pressure when the water inlet pressure is too high to prevent the pipeline connection from loosening due to excessive local water pressure.

[0021] During the specific implementation of the present invention, the water pump of the fire truck is connected to the municipal waterway or water storage station through a pipeline, the hand-lift pump is placed on the ground and connected to the fire truck through a pipeline. When extinguishing a fire in a super-high-rise building or a location that the fire truck cannot reach, the number of coupled water suppliers is selected according to the distance, the water inlet connecting pipe is connected to the hand-lift pump, the water outlet connecting pipe is connected to the water supply pipe connector, the water supply pipe connector is connected to the water inlet connecting pipe of the next coupled water supplier body, and finally connected to the water supply terminal pipeline. When the water pressure provided by the hand-lift pump is too high, the automatic pressure relief valve opens to relieve the pressure and then closes.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
