The fire-fighting pipeline is mainly used for water supply, gas supply, smoke exhaust, fire-fighting spraying and the like, and needs to meet the performance requirements of fire resistance, pressure resistance and corrosion resistance. When laying the fire-fighting pipeline, the pipeline needs to be fixed by a fixing device, but the existing pipeline fixing device can only fix the pipeline and has a single function, which cannot meet the use requirements. SUMMARY

[0003] The present application provides a fire-fighting water spraying pipeline laying device and a building method thereof, which solve the above technical problems.

[0004] The technical solutions of the present application for solving the above technical problems are as follows:

[0006] On the basis of the above technical solutions, the present application can also be improved as follows.

[0007] Further, the first shell and the second shell are provided with limiting plates, and the flanges at both ends of the Laval nozzle and the pipeline booster pump are limited by the limiting plates of the first shell and the second shell.

[0008] Further, a clamping groove is formed in the clamp, and a pressing plate is installed on the clamp through the clamping groove.

[0009] Further, both ends of the pressing plate are provided with threaded columns, and the pressing plate and the clamp are locked and fixed by nuts and the threaded columns.

[0010] Further, positioning grooves are formed in the first shell and the second shell, and the installation positions of the connecting pipe, the pipeline booster pump and the Laval nozzle are limited by the positioning grooves of the first shell and the second shell.

[0011] Further, the first shell and the second shell are provided with fixing plates, the fixing plates are provided with fixing holes, and the fixing plates are fixed on the plane through the fixing holes and bolts.

[0012] Further, the first shell and the pipeline booster pump are cross arranged.

[0013] Further, the lower surface of the connecting pipe is provided with spray heads, and the spray heads are uniformly distributed on the connecting pipe.

[0014] Further, the spray head is a fire-fighting spray head.

[0015] A construction method of a fire-fighting water spraying pipeline laying device, comprising the following steps:

[0016] S1, the Laval nozzle and the pipeline booster pump are communicated with the connecting pipe through the flange plate;

[0017] S2, the flange plates at the connecting positions of the Laval nozzle and the pipeline booster pump and the connecting pipe are limitedly installed in the first shell and the second shell through the limiting plates;

[0019] S4, the first shell and the second shell are fixed on the ceiling through the fixing holes on the fixing plates and the bolts;

[0020] S5, the connecting pipe is communicated with the water source through the delivery pump, and the fire-fighting water spraying pipeline laying is completed

[0021] The beneficial effects of the present application are: simple structure, high flexibility and strong reliability. The design of the internal fixing plate and the positioning groove can ensure that the Laval nozzle and the pipeline booster pump are stably installed in the accommodating cavity and the position is limited, thereby improving the stability of the whole device during operation. The Laval nozzle is a nozzle that can convert liquid flow into high-speed airflow, and its principle is based on Bernoulli's theorem and the continuity equation. When water or other liquids pass through the converging nozzle, they enter the converging section and accelerate with the gradual decrease of pressure, and finally reach the maximum flow rate at the nozzle throat. At this time, according to the continuity equation, the flow rate is inversely proportional to the speed, so the pressure of the liquid also reaches a minimum value. Next, the fluid jumps out of the nozzle throat and expands freely, generating a strong turbulent flow that produces a negative pressure effect on the surrounding air, forming a local low-pressure area, thereby causing air to be sucked in and forming a mixed airflow. Since the interaction between liquid molecules is very strong, water or other liquids can transmit momentum and energy. After the high-speed liquid and the sucked air are mixed, a high-speed airflow is formed at the nozzle outlet, which has a thrust effect similar to a rocket nozzle. In this way, the Laval nozzle can produce a high-speed, high-impact water column with a small water flow, and the Laval nozzle has the characteristics of accelerating fluid and effectively increasing thrust, which can make the ejected water flow have a larger impact force and a wider coverage range, thereby improving the efficiency of fire fighting and rescue work, and further ensuring the water flow pressure in the pipeline through the booster pump.

The design of the fixing plates 15 and the positioning grooves 17 in the device can ensure that the Laval nozzle 10 and the pipeline booster pump 5 are stably installed in the containing cavities 11 and the positions of the Laval nozzle 10 and the pipeline booster pump 5 are limited, and the stability of the device as a whole during operation is improved. The Laval nozzle 10 is a nozzle that can convert liquid flow into high-speed airflow, and its principle is based on Bernoulli's theorem and the continuity equation. When water or other liquids pass through the converging nozzle, they enter the converging section and accelerate with the gradual decrease in pressure, finally reaching the maximum flow rate at the nozzle throat; at this time, according to the continuity equation, the flow rate is inversely proportional to the speed, so the pressure of the liquid also reaches a minimum value.

[0035] The fire water spraying pipeline laying device based on the embodiment 1 has the advantages of simple structure, high flexibility and high reliability.
