Description

Technical Field

[0002] With the rapid development of today's social economy, my country's fire truck industry has also developed rapidly. Especially after the introduction of foreign advanced technology, domestic high-power, long-distance, and large-flow water supply vehicles have made great breakthroughs, making a significant contribution to large fires, especially petrochemical industry fires.

[0003] The inventors have found that the flow rate of the existing fire water supply system is basically 300L / S. The fire truck chassis engine is used to drive the submersible pump to draw water and send it to the booster pump. Then an engine is installed on the vehicle to drive the booster pump to supply water to the outside. Two engines can meet the requirements; however, in order to meet the water supply needs of large-scale fires, the water supply needs to be increased to more than 400L / S, and the power of the original fire truck chassis engine that drives the submersible pump is obviously insufficient, and it cannot provide enough water to the booster pump so that the booster pump can increase the water supply to more than 400L / S.

[0028] The present embodiment provides a fire truck, which may be any model and type of fire truck. In order to solve the problem of insufficient water supply in the water supply system in the prior art, the present embodiment provides a vehicle-use coordinated water supply system, as described below.

[0029] like Figure 1 As shown, the utility model provides a vehicle-use coordinated water supply system, including a first water pump 10, a second water pump 20, a booster pump 30, a first engine 40, a second engine 50 and a third engine 60; the first water pump 10 and the second water pump 20 are connected to the water inlet of the booster pump 30, the first engine 40 drives the first water pump 10, the second engine 50 drives the second water pump 20, and the third engine 60 drives the booster pump 30. In detail, the first engine 40 and the third engine 60 in this embodiment are the original fire truck chassis engine and the original booster pump 30 engine, respectively, and the second engine 50 is an additional engine.

[0030] It can be understood that in this solution, the first engine 40 and the second engine 50 respectively drive the first water pump 10 and the second water pump 20 to draw water and send it to the water inlet of the booster pump 30, and the third engine 60 drives the booster pump 30 to supply water to the outside. The three engines work together to ensure that the booster pump 30 has sufficient water supply to meet the water supply demand of the water supply system.

[0031] In a preferred embodiment, the first water pump 10 and the second water pump 20 are connected to the booster pump 30 via a Y-shaped pipeline 70. In detail, the Y-shaped pipeline 70 is a PE fire-fighting pipe, which has the characteristics of corrosion resistance and high pressure resistance.

[0032] In a preferred embodiment, a first valve 80 is provided on the Y-shaped pipeline 70 , and the first valve 80 is used to open or close the passage between the first water pump 10 and the boosting pump 30 .

[0033] It is understandable that when the first water pump 10 is not needed, the first valve 80 can be used to close the passage between the first water pump 10 and the booster pump 30 to prevent water from flowing back into the first water pump 10 when the second water pump 20 is in use.

[0034] In a preferred embodiment, a second valve 90 is provided on the Y-shaped pipeline 70 , and the second valve 90 is used to open or close the passages of the second water pump 20 and the boosting pump 30 .

[0035] It can be understood that the function of the second valve 90 is the same as that of the first valve 80. When the second water pump 20 is not needed, the second valve 90 can be used to close the passage between the second water pump 20 and the booster pump 30 to prevent water from flowing back into the second water pump 20 when the first water pump 10 is in use.

[0036] In a preferred embodiment, the vehicle coordinated water supply system further includes an electronic control unit 100 , which is connected to the first engine 40 , the second engine 50 and the third engine 60 .

[0037] It is understandable that one electronic control unit 100 can control the rotation speeds of three engines. According to actual needs, one engine can be selected for use alone or multiple engines can be used together, which is convenient for operation.

[0038] In a preferred embodiment, the vehicle coordinated water supply system further includes an inlet pressure sensor 110, which is disposed at the water inlet of the boost pump 30 and connected to the electronic control unit 100. It can be understood that the inlet pressure sensor 110 is mainly used to detect the pressure value of the water inlet of the boost pump 30 to ensure that the boost pump 30 has sufficient water supply, and the electronic control unit 100 can calculate the inlet flow of the boost pump 30 according to the inlet pressure value, that is, the water supply of the first engine 40 and the second engine 50.

[0039] In a preferred embodiment, the vehicle coordinated water supply system further includes an outlet pressure sensor 120, which is disposed at the water outlet of the booster pump 30 and connected to the electronic control unit 100. It can be understood that the outlet pressure sensor 120 is mainly used to detect the outlet pressure value of the booster pump 30, and then calculate the water output of the booster pump 30 to meet the drainage needs of large fires.

[0040] Furthermore, both the first water pump 10 and the second water pump 20 are buoyant pumps. It is understandable that the buoyant pump is small in size, light in weight, simple and quick to operate, can directly use the nearby water source, is flexible, and has a large water output.

[0041] In a preferred embodiment, the vehicle coordinated water supply system further includes a flow meter 130, which is disposed at the water outlet of the booster pump 30 and connected to the electronic control unit 100. It is understandable that the flow meter 130 is used to detect the actual water output of the booster pump 30.

[0042] The vehicle coordinated water supply system provided in this embodiment has the following advantages:

[0043] In this embodiment, the first engine 40 and the second engine 50 respectively drive the first water pump 10 and the second water pump 20 to take water and send it to the water inlet of the boost pump 30, and the third engine 60 drives the boost pump 30 to supply water to the outside; in addition, an electronic control unit 100 is used to control the rotation speed of the three engines. The electronic control unit 100 monitors the water pressure at the water inlet and the water outlet of the boost pump 30, controls the water supply of the first engine 40 and the second engine 50, and makes the water pressure at the water inlet of the boost pump 30 positive, thereby ensuring that the boost pump 30 has sufficient water supply. The three engines work together to ensure that the boost pump 30 has sufficient water supply, thereby meeting the water supply demand of the water supply system.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
