Description

Technical Field

[0001] This invention relates to the field of fire truck technology, specifically to a water-based new energy electric fire truck. Background Technology

[0002] With increasing environmental awareness and the continuous development of new energy technologies, water-based new energy electric fire trucks are gradually becoming a new trend in the fire protection field. Water-based new energy electric fire trucks use water as the extinguishing agent, offering advantages over traditional fuel-powered fire trucks in terms of environmental friendliness, safety, and energy efficiency.

[0003] Currently, fire extinguishing systems in water-based fire trucks generally employ direct water supply or small-volume water-based fire extinguishing tanks. Furthermore, the water-based extinguishing agents in these systems are often pre-prepared. When the extinguishing agent is used up and the fire is not completely extinguished, direct water supply is the only option for further fire suppression. Therefore, this method is not very effective at extinguishing fires.

[0004] Therefore, it is necessary to provide a water-based new energy electric fire truck to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-based new energy electric fire truck, comprising a new energy vehicle body, a water tank disposed in the body of the new energy vehicle, and a water spray frame disposed on the roof of the new energy vehicle. The drain end of the water tank is connected to the lower port of a three-way pipe. An online batching system is installed on the roof of the new energy vehicle. The online batching system includes multiple mixing and proportioning units arranged in series. The mixing and proportioning unit located on the water inlet side of the online batching system is connected to the middle port of the three-way pipe, and the mixing and proportioning unit located on the water outlet side of the online batching system is connected to the water spray frame. The lower port and upper port of the three-way pipe are respectively provided with a water valve one and a water valve two.

[0006] Furthermore, as a preferred embodiment, the mixing configuration unit includes a base, a pressurizing pipe, and a mixing tank. The pressurizing pipe and the mixing tank are respectively mounted on the base. A connecting cover is connected to the middle tank wall of the mixing tank.

The pressurizing pipe is equipped with an online mixing mechanism for quantitatively guiding the raw materials in the mixing tank.

[0007] Furthermore, as a preferred embodiment, the online batching mechanism includes a mixing column, a telescopic component, and a quantitative feeding component. The mixing column is fixedly assembled with the pressurization pipe, and the mixing column is provided with an axial guide hole, a receiving hole, and a flow hole, respectively. The mixing column is also provided with a discharge hole that communicates with the receiving hole and the connecting cover, respectively.

[0008] The quantitative feeding component is installed on the receiving hole and is used to control the quantitative amount of raw material fed from the feeding hole.

[0009] Furthermore, as a preferred embodiment, the telescopic assembly includes a guide post slidably assembled through the guide hole, a rotating fan bearing is mounted on the end of the guide post located on the water inlet side of the booster pipe, one end of the elastic telescopic frame is coaxially fixedly connected to the rotating fan, and a baffle is fixed to the other end of the elastic telescopic frame. When the rotating fan rotates and drives the baffle to rotate circumferentially, it can block or disengage from the flow hole. When the baffle blocks the flow hole, the fluid in the booster pipe can push the elastic telescopic frame to contract. When the baffle disengages from the flow hole, the elastic telescopic frame resets. A tail plate seat is fixed to the end of the guide post located on the water outlet side of the booster pipe.

[0010] Furthermore, as a preferred embodiment, the guide column central bearing is equipped with a shaft, one end of which is coaxially fixed with the rotating fan, and the other end of which is equipped with a turbulence tail frame.

[0011] Furthermore, as a preferred embodiment, the quantitative feeding assembly includes a plug and a quantitative block. The plug is fixed to the end of the receiving hole on the water inlet side of the booster pipe, and the quantitative block is slidably mounted on the receiving hole. The end of the quantitative block away from the plug is mounted on the tail plate seat, and the quantitative block is provided with a quantitative cavity for receiving the feed from the feed hole. When the plug moves the quantitative block toward the water outlet side of the booster pipe, the quantitative cavity is exposed outside the receiving hole. The quantitative cavity is also provided with a quantitative control component.

[0012] Furthermore, as a preferred embodiment, the metering block facing the plug is also provided with a groove, and a sliding hole is provided between the groove and the metering cavity to connect the two.

Detailed Implementation

[0026] Reference Figure 1-8 The present invention provides a technical solution: a water-based new energy electric fire truck, including a new energy vehicle body 1, a water tank 3 installed in the body of the new energy vehicle body 1, and a water spray frame 2 installed on the roof of the new energy vehicle body 1. The drain end of the water tank 3 is connected to the lower port of a three-way pipe 6. An online batching system 4 is installed on the roof of the new energy vehicle body 1. The online batching system 4 includes multiple mixing and proportioning units 5 arranged in series. The mixing and proportioning unit 5 located on the water inlet side of the online batching system 4 is connected to the middle port of the three-way pipe 6, and the mixing and proportioning unit 5 located on the water outlet side of the online batching system 4 is connected to the water spray frame 2. The lower port and the upper port of the three-way pipe 6 are respectively provided with a water valve 61 and a water valve 62.

[0027] In this embodiment, the water supply methods for the sprinkler system are as follows: Water supply method one: when water valve one is open and water valve two is closed, water is supplied by water tank 3; Water supply method two: when water valve one is closed and water valve two is open, water can be supplied from an external water source. In this design, regardless of whether water supply method one or water supply method two is used, the water-based fire extinguishing agent can be prepared online by the online batching system 4 before the sprinkler system sprays water from the external water source or the water tank. That is to say, it is not necessary to pre-prepare the raw materials a, b, c, and e required for the preparation of the water-based fire extinguishing agent. Therefore, in this design, by setting up a corresponding number of mixing and proportioning units based on the required quantity and volume of raw materials for the preparation of the water-based fire extinguishing agent, the water-based fire extinguishing agent can be prepared and used in real time when fire extinguishing is needed. This avoids the situation where the prepared water-based fire extinguishing agent expires due to long-term non-use, thus saving resources. In addition, depending on the type of fire, the required water-based fire extinguishing agent can be prepared according to the actual situation, making fire extinguishing more precise and improving fire extinguishing efficiency and effect.

[0028] In this embodiment, the mixing and configuration unit 5 includes a base 5, a pressurizing pipe 52, and a mixing tank 53. The pressurizing pipe 52 and the mixing tank 53 are respectively mounted on the base 5. The middle wall of the mixing tank 53 is connected to a connecting cover 54, which is connected to the mixing tank 53. The connecting cover 54 is equipped with a one-way valve 55. The pressurizing pipe 52 is equipped with an online mixing mechanism 7 for quantitatively guiding the raw materials in the mixing tank 53. When the corresponding mixing tank 53 is required to participate in the online preparation of water-based fire extinguishing agent, the corresponding one-way valve can be opened to complete the preparation of water-based fire extinguishing agent that meets the requirements of on-site fire extinguishing. The operation is simple.

[0029] In this embodiment, the online batching mechanism 7 includes a mixing column 71, a telescopic component 72, and a quantitative feeding component 8. The mixing column 71 is fixedly assembled with the pressurizing pipe 52, and the mixing column 71 is provided with an axial guide hole 713, a receiving hole 711, and a flow hole 714. The mixing column 71 is also provided with a discharge hole 712 that communicates with the receiving hole 711 and the connecting cover 54 respectively.

[0030] The quantitative feeding component 8 is installed on the receiving hole 711 and is used to control the quantitative amount of raw material fed from the feeding hole 712. The telescopic component 72 is installed on the guide hole 713 and is used to control the output of the quantitatively fed raw material by the quantitative feeding component 8.

[0031] The telescopic assembly 72 includes a guide post 721 slidably mounted through a guide hole 713. A rotating fan 722 is mounted on the end bearing of the guide post 721 located at the water inlet end of the booster pipe 52. One end of an elastic telescopic frame 723 is coaxially fixedly connected to the rotating fan 722. A baffle 724 is fixed to the other end of the elastic telescopic frame 723. When the rotating fan 722 rotates, it drives the baffle 724 to rotate circumferentially, which can block or disengage from the flow hole 714. When the baffle 724 blocks the flow hole 714, the fluid in the booster pipe can push the elastic telescopic frame 723 to contract. When the baffle 724 disengages from the flow hole 714, the elastic telescopic frame 723 resets. The guide post 721 located at the water outlet end of the booster pipe 52... 1. A tail plate seat 725 is fixed at one end; that is, when the water spray frame is activated for spraying, the fluid passing through the mixing and proportioning unit serves as the power to drive the telescopic component, thereby causing the rotating fan to rotate and the baffle to pass through the flow hole during the circulation process. When the quantitative material guiding component moves against the flow direction along the receiving hole 711, it can receive the raw material in the discharge hole 712. When the quantitative material guiding component moves with the flow direction along the receiving hole 711, it can release the received raw material into the water source in the pressurization pipe and be flushed by the water flow. In addition, when the flow rate changes, the mixing rate will also be increased, thereby ensuring that the raw material and water source of the online prepared water-based fire extinguishing agent are mixed more evenly, thereby improving the fire extinguishing quality.

[0032] The guide column 721 has a central bearing with a shaft 9 installed. One end of the shaft 9 is coaxially fixed with the rotating fan 722, and the other end of the shaft 9 is equipped with a stirring tail frame 91, which helps to make the raw materials released into the water source mix more thoroughly and comprehensively with the water source within a short travel range.

[0033] In this embodiment, the quantitative feeding assembly 8 includes a plug 81 and a quantitative block 82. The plug 81 is fixed to the end of the receiving hole 711 on the water inlet side of the booster pipe 52. The quantitative block 82 is slidably mounted on the receiving hole 711. The end of the quantitative block 82 away from the plug 81 is mounted on the tail plate seat 725. The quantitative block 82 is provided with a quantitative cavity 821 for receiving the material from the feeding hole 712. When the plug 81 moves the quantitative block 82 towards the water outlet side of the booster pipe 52, the quantitative cavity 821 is exposed outside the receiving hole 711. The quantitative cavity 821 is also provided with a quantitative control assembly 84. By moving the quantitative block back and forth through the tail plate seat, the raw material in the feeding hole can be filled into the quantitative cavity. Figure 7 As shown, the metering chamber has a through-hole structure to allow the raw materials to mix into the water more quickly.

[0034] The metering block 82, located on the side facing the plug 81, is provided with a groove 823. A sliding hole 822 connects the groove 823 and the metering cavity 821. A compression spring 831 is connected to the plug 81. The other end of the compression spring 831 is connected to a sliding post 832 that slides in cooperation with the groove 823. A sliding rod 833, which slides through the sliding hole 822, is coaxially fixed to the sliding post 832. The other end of the sliding rod 833 is fixed with a stop 834 located in the metering cavity 821. When the compression spring 831 is in a free state, the stop 834 is located at the end of the receiving hole 711 on the side away from the plug 81. That is, when the metering block 82 is in a free state, the stop 834 is located at the end of the receiving hole 711 on the side away from the plug 81. When the metering block moves towards the block in the direction of water flow, the compression spring is compressed, placing the baffle at the end of the metering chamber orifice in the direction of water flow, allowing the raw material to enter the metering chamber orifice. When the metering block moves away from the block in the direction of water flow, the compression spring is stretched, further driving the raw material out of the metering chamber orifice. When the raw material is completely discharged, the compression spring returns to its free state, and the baffle is positioned outside the end of the receiving hole, sealing the receiving hole. This prevents the metering block from driving water into the metering chamber orifice when it moves in the direction of water flow, creating a backflow prevention effect and ensuring safe and quantitative feeding of the raw material.

[0035] The quantitative control component 84 includes a telescopic device 841 and a positioning cover 842. The telescopic device 841 is installed at the end of the quantitative block 82 on the side facing the water outlet of the booster pipe 52. The output end of the telescopic device 841 is equipped with a positioning cover 842 that slides with the quantitative cavity orifice 821. Therefore, by adjusting the size of the quantitative cavity orifice through the telescopic device, the proportion of each batching tank participating in online batching can be adjusted.

[0036] The positioning cover 842 has an opening on the shell surface facing the axis of the mixing column 71, and the end of the metering block 82 located at the installation position of the telescoping device 841 and facing the axis of the mixing column 71 has a connecting groove.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
