DETAILED DESCRIPTION

[0035] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown:

[0037] Embodiment 1: The present invention provides a fire truck water source pressurized high-efficiency fire extinguishing device and method, comprising:

[0038] A base 1, a driving mechanism 5 is installed on the top of the base 1, a front end of the driving mechanism 5 is connected to a pressurizing mechanism 4, and one side of the pressurizing mechanism 4 is connected to a water storage tank 6;

[0039] The driving mechanism 5 includes a commutator 503 mounted on the top of the base 1, a driving motor 502 is installed on the top of the base 1 at the front end of the commutator 503, the output end of the driving motor 502 is connected to the input end of the commutator 503 through a belt, the output end of the commutator 503 is connected to a turntable 504, a fixed column 505 is installed on the top of the turntable 504, and the outer periphery of the fixed column 505 is rotatably connected to a transmission rod 506;

[0040] The pressurizing mechanism 4 includes a connecting rod 403 rotatably connected to the transmission rod 506, a piston 402 is connected to the end of the connecting rod 403, a T-shaped pressurizing tube 401 is sleeved on the periphery of the piston 402, and both sides of the T-shaped pressurizing tube 401 are connected to a one-way valve 404, and the one-way valve 404 is connected to the water storage tank 6 through a connecting pipe 406;

[0041] A water delivery pipe 10 is installed on the outer wall of the water tank 6 , a pressure detector 7 is installed on the top of the water tank 6 , a liquid level meter 8 is installed on the top of the water tank 6 , and an electric pressure relief valve 9 is installed on the top of the water tank 6 .

[0042] Among them, a water sealing plate is installed at the end of the water supply pipe 10 by bolts, and the liquid level meter 8 adopts a multi-point monitoring liquid level detector, which can detect the water level at multiple positions inside the water tank 6 when in use.

[0043] As can be seen from the above, after the device is assembled on the fire truck, it is moved to the fire rescue site under the drive of the fire truck, and the device is removed from the fire truck and moved to a nearby water source, and the pressurizing mechanism 4 is connected to the external water source, and after the sealing plate on the water pipe 10 is removed, the water pipe 10 is connected to the fire hose and the fire hose;

[0044] When the external water source has no pressure, the driving mechanism 5 is started, and the driving motor 502 drives the turntable 504 to rotate through the commutator 503 during operation. During the rotation of the turntable 504, the connecting rod 403 and the piston 402 are pulled by the fixing column 505 and the transmission rod 506 to reciprocate inside the T-shaped pressurized tube 401. Under the cooperation with the one-way valve 404, the one-way valve 404 on the other side is used to draw the external water source into the T-shaped pressurized tube 401, and after pressurization, the water is transported to the inside of the water storage tank 6 through the one-way valve 404 on one side and the connecting pipe 406 for storage;

[0045] During the operation of the device, the pressure detector 7 and the liquid level meter 8 detect the pressure and water level inside the water tank 6. When the gas pressure inside the water tank 6 is too high, the electric pressure relief valve 9 is opened to discharge the gas inside the water tank 6. When the water pressure inside the water tank 6 is too high, the electric pressure relief valve 9 is also opened to release the pressure, and at the same time, the power output of the driving mechanism 5 is reduced to reduce the pressure of the water tank 6.

[0046] The water stored in the water tank 6 is continuously supplied to the fire hose through the water pipe 10 to avoid intermittent supply.

[0047] By installing a pressurizing mechanism 4 and a driving mechanism 5, it is possible to improve the pumping capacity of the device while also pressurizing the drainage of the device. The water extracted by the pressurizing mechanism 4 and the driving mechanism 5 is stored in a water storage tank 6 and stably output to the outside through a water pipe 10, thereby avoiding intermittent water supply during firefighting and improving the water supply capacity of the device.

[0048] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown:

[0049] Specifically, regarding the above-mentioned pressurizing mechanism 4, the pressurizing mechanism 4 further includes a water inlet pipe 405, and the water inlet pipe 405 is connected to one side of the one-way valve 404, and the conducting direction of the one-way valve 404 is the same.

[0050] The shape and length of the water inlet pipe 405 can be changed according to actual conditions.

[0051] As can be seen from the above, by connecting the connecting pipe 406 with the external water source, the external water source can be guided to the inside of the device after the connection, thereby providing hydraulic supply for fire fighting. By making the flow direction of the one-way valve 404 the same direction, one can be kept open and the other automatically closed during the movement of the piston 402, thereby realizing continuous pressure delivery in one direction.

[0052] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 6 As shown:

[0053] Specifically, regarding the above-mentioned water storage tank 6, an L-shaped inclined filter plate 11 is installed inside the water storage tank 6, and the highest point of the cross section of the L-shaped inclined filter plate 11 is lower than the position of the through hole connecting the water storage tank 6 and the pressurizing mechanism 4;

[0054] A plurality of material collecting boxes 12 are installed at the bottom of the water storage tank 6 at the rear end of the L-shaped inclined filter plate 11 , and a detachable sealing cover 13 is installed at the bottom of the material collecting box 12 .

[0055] The L-shaped inclined filter plate 11 is provided with mesh holes.

[0056] As can be seen from the above, the water entering the water storage tank 6 through the through hole of the pressurizing mechanism 4 contacts with the L-shaped inclined filter plate 11, and the impurities in the water are filtered by the mesh holes on the L-shaped inclined filter plate 11. The filtered impurities are subsequently flushed by the water entering the water storage tank 6 through the through hole and enter the collection box 12 along the top surface of the L-shaped inclined filter plate 11 for centralized storage. When the device stops running, the sealing cover 13 is removed from the collection box 12, so that the user can clean the impurities inside the collection box 12 after removal.

[0057] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown:

[0058] Specifically, regarding the above-mentioned driving mechanism 5 , the driving mechanism 5 further includes a mounting seat 501 mounted on the bottom of the commutator 503 , and the bottom of the mounting seat 501 is connected to the top of the base 1 .

[0059] As can be seen from the above, the mounting seat 501 can limit the position of the commutator 503 during use, ensuring that the commutator 503 will not deviate or shake during the transmission process, making the transmission between the pressurizing mechanism 4 and the driving mechanism 5 more stable.

[0060] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown:

[0061] Specifically, regarding the top plate 2 and the pressurizing mechanism 4, the top plate 2 is installed at the bottom of the pressurizing mechanism 4, and the top of the top plate 2 is installed with a protective cover 3 that is sleeved around the pressurizing mechanism 4 and the driving mechanism 5;

[0062] A plurality of support rods 15 are installed between the bottom of the top plate 2 and the base 1 .

[0063] As can be seen from the above, the protective cover 3 can wrap and protect the local structures of the pressurizing mechanism 4 and the driving mechanism 5 when in use, so as to prevent the pressurizing mechanism 4 and the driving mechanism 5 from causing harm to the firefighters after contact with the firefighters during the transmission process, thereby improving the protection effect. By using the support rod 15, the top plate 2 can be supported during use, making the device structure more stable.

[0064] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown:

[0065] Specifically, regarding the above-mentioned base 1 , a plurality of wheels 14 are installed on both sides of the bottom of the base 1 .

[0066] Wherein, each wheel 14 is additionally equipped with a foot valve.

[0067] As can be seen from the above, the wheels 14 can support the bottom of the base 1 during use, reduce the contact area between the base 1 and the external structure, and reduce the resistance encountered during the movement of the device, so that the user can move the position of the device according to needs and optimize the use process.

[0068] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown:

[0069] Embodiment 2: A method for using a water source pressurized high-efficiency fire extinguishing device in a fire truck, the steps are as follows:

[0070] Step 1: assemble the device on the fire truck, remove the sealing plate on the water pipe 10, and connect the water pipe 10 to the fire hose through a pipeline to complete the assembly, so that the firefighters can transport the device to the fire scene for use according to their needs;

[0071] Step 2: After the assembly is completed, the fire truck will transport the device to the place where the fire needs to be extinguished when on duty, remove the device from the fire truck, use the wheels 14 to move the device to the nearest fire hydrant or other water source, and use the pipeline to connect the water inlet pipe 405 with the external water source. After the connection is completed, the external water source can be guided to the inside of the device through the water inlet pipe 405 for storage and pressurization, so as to be fully prepared for fire extinguishing;

[0072] Step 3, after the connection is completed, the driving mechanism 5 is started. During the operation of the driving motor 502, the output end transmits power to the input end of the commutator 503 through a belt, so that the output end of the commutator 503 drives the turntable 504 to rotate. During the rotation of the turntable 504, the transmission rod 506 pulls the connecting rod 403 to reciprocate inside the T-shaped pressurized tube 401, and the piston 402 moves at the same time under the drive of the T-shaped pressurized tube 401. During the forward movement of the piston 402, the gas or The liquid is transported to the inside of the water storage tank 6 through the one-way valve 404 on one side of the T-shaped pressurizing tube 401. When the piston 402 moves backward, the one-way valve 404 on one side of the T-shaped pressurizing tube 401 is closed, and the one-way valve 404 on the other side is opened to extract the external water source or the gas inside the water inlet pipe 405, forming a negative pressure, and the external water source is drawn into the inside of the pressurizing mechanism 4. In this way, water pumping and pressurization are achieved reciprocatingly. The power output by the driving motor 502 can be adjusted according to specific needs to avoid the situation where the power is too strong and the device is overloaded and damaged;

[0073] Step 4: The gas and liquid delivered by the pressurizing mechanism 4 enter the interior of the water tank 6 through the connecting pipe 406. The pressure and water level inside the water tank 6 are detected by the pressure detector 7 and the liquid level gauge 8. The operation of the driving mechanism 5 and the electric pressure relief valve 9 is controlled according to the water level and pressure inside the water tank 6, so that the interior of the water tank 6 can always maintain stable water storage and the water delivery pipe 10 can output stably and continuously. When the gas pressure inside the water tank 6 is too high, the electric pressure relief valve 9 is opened to discharge the gas inside the water tank 6. When the water pressure inside the water tank 6 is too high, the electric pressure relief valve 9 is also opened to release the pressure, and at the same time, the power output of the driving mechanism 5 is reduced to reduce the pressure of the water tank 6.

[0074] Step 5: Filter the impurities in the liquid entering the water storage tank 6 through the L-shaped inclined filter plate 11, and under the guidance of the L-shaped inclined filter plate 11, the filtered impurities are accumulated inside the aggregate box 12. After the fire extinguishing effect is completed, open the sealing cover 13 to clean the impurities inside the aggregate box 12, disconnect the device from other structures, and retract it to the fire truck to complete the stable pressurized fire extinguishing.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
