Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted fire pump technology, specifically to a manual foam proportioner for vehicle-mounted fire pumps. Background Technology

[0002] Vehicle-mounted fire pumps are key equipment on fire trucks, mainly used to transport water or other fire extinguishing media to respond to fire rescue missions. Vehicle-mounted fire pumps are classified by the media they transport: fire water pumps (transport water), foam liquid pumps (transport foam liquid), and priming fire pumps (transport air).

[0003] Currently, existing vehicle-mounted fire pumps do not have a mixing structure and cannot mix the pumped clean water with foam. Therefore, a manual foam proportioner for vehicle-mounted fire pumps is proposed. The electric ball valve is opened by manually controlling the control panel, allowing foam to flow into the Venturi tube and mix with the clean water flowing into the Venturi tube before being sprayed out. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a manual foam proportioner for vehicle-mounted fire pumps. The electric ball valve is opened by manually controlling the control panel, allowing foam to flow into the venturi tube, mix with the clean water flowing into the venturi tube, and then be sprayed out.

[0005] The technical solution adopted by this utility model to solve its technical problem is a manual foam proportioner for vehicle-mounted fire pumps, including a foam feed pipe, an electric ball valve connected to the top of the foam feed pipe through a threaded groove, a venturi tube connected to the top of the electric ball valve through a pipe joint, and a manual operation panel provided on one side of the electric ball valve.

[0006] A fixing component is provided on the outside of the foam feed pipe. The fixing component includes a first collar fixedly sleeved on the outside of the foam feed pipe. A long screw is welded to one side of the first collar. An internal threaded sleeve is sleeved on the outside of the long screw. A hook is rotatably connected to the end of the internal threaded sleeve away from the long screw.

[0007] By adopting the above technical solution, the electric ball valve is opened by manually controlling the control panel to allow foam to flow through the foam feed pipe to the venturi pipe and mix with clean water. The connection stability between the foam feed pipe and the vehicle-mounted fire pump can be improved by using a long screw and an internal threaded sleeve.

[0008] Specifically, a second sleeve ring is fixedly sleeved on the outside of the venturi tube, and an L-shaped connecting plate is welded between the second sleeve ring and the first sleeve ring. The manual operation panel is mounted on one side of the L-shaped connecting plate via a mounting bracket.

[0009] Specifically, a flow sensor is fitted onto one side of the foam feed pipe, and the detection end of the flow sensor is located inside the foam feed pipe.

[0011] Specifically, an anti-slip sleeve is provided on the outer side of the internal threaded sleeve.

[0012] Specifically, one end of the venturi tube is connected to a transparent sleeve via a threaded groove.

[0013] The beneficial effects of this utility model are:

[0014] (1) The manual foam proportioner for vehicle-mounted fire pumps described in this utility model is used to control the opening of an electric ball valve when the vehicle-mounted fire pump pumps clean water through the Venturi tube.

[0022] The electric ball valve is opened via the manual control panel, allowing foam to flow into the venturi tube, mix with the clean water flowing into the venturi tube, and then be sprayed out. Figure 1-3 As shown, the present invention provides a manual foam proportioner for a vehicle-mounted fire pump, comprising a foam feed pipe 1, an electric ball valve 3 connected to the top of the foam feed pipe 1 via a threaded groove, a venturi tube 4 connected to the top of the electric ball valve 3 via a pipe joint, and a manual operation panel 5 provided on one side of the electric ball valve 3.

[0023] A fixing component 2 is provided on the outside of the foam feed pipe 1. The fixing component 2 includes a first collar 201 fixedly sleeved on the outside of the foam feed pipe 1. A long screw 204 is welded to one side of the first collar 201. An internal threaded sleeve 205 is sleeved on the outside of the long screw 204. A hook 206 is rotatably connected to the end of the internal threaded sleeve 205 away from the long screw 204.

[0024] During use, the electric ball valve 3 is opened by manually controlling the control panel 5 to allow the foam to flow through the foam feed pipe 1 to the venturi pipe 4 and mix with clean water. The long screw 204 and the internal threaded sleeve 205 can improve the connection stability between the foam feed pipe 1 and the vehicle-mounted fire pump.

[0025] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a second sleeve ring 202 fixedly sleeved on the outside of the venturi tube 4, an L-shaped connecting plate 203 welded between the second sleeve ring 202 and the first sleeve ring 201, and the manual operation panel 5 mounted on one side of the L-shaped connecting plate 203 by a mounting bracket.

[0026] In use, the L-shaped connecting plate 203 connects the second ring 202 and the first ring 201 to improve the connection stability between the venturi tube 4 and the foam feed tube 1.

[0027] For example, such as Figure 1 As shown, the present invention also includes a flow sensor 6 sleeved on one side of the foam feed pipe 1, and the detection end of the flow sensor 6 is located inside the foam feed pipe 1.

[0028] When in use, the flow sensor 6 can detect the flow rate of foam in the foam feed pipe 1.

[0029] For example, such as Figure 1 As shown, this utility model also includes a current output terminal of the manual operation panel 5 that is electrically connected to the current input terminal of the electric ball valve 3 via a power cord.

[0030] In use, the manual operation panel 5 is used to control the opening and closing of the electric ball valve 3 and its opening and closing angle.

[0031] For example, such as Figure 3 As shown, the present invention also includes an anti-slip sleeve 207 provided on the outer side of the internal threaded sleeve 205.

[0032] When in use, the transparent sleeve 7 is designed to prevent slippage, so that the person holding the internal threaded sleeve 205 will not slip when rotating it.

[0033] For example, such as Figure 2 As shown, the present invention also includes a transparent sleeve 7 connected to one end of the venturi tube 4 via a threaded groove.

[0034] When in use, the foam mixed with water in the venturi tube 4 flows out through the transparent sleeve 7, and the mixing of water and foam can be observed through the transparent sleeve 7.

[0035] When using this utility model, the personnel fix one end of the Venturi tube 4 to the outlet end of the vehicle-mounted fire pump, fix the bottom end of the foam feed pipe 1 to the foam pumping equipment, and connect the device to an external power source using a power cord.

[0036] When the vehicle-mounted fire pump pumps clean water out through the Venturi tube 4, the personnel control the electric ball valve 3 to open through the manual operation panel 5. After the electric ball valve 3 is opened, the foam flows into the Venturi tube 4 through the foam feed pipe 1, mixes with the clean water in the Venturi tube 4 and is then sprayed out.

[0037] The detection end of the flow sensor 6 is located inside the foam feed pipe 1. It can detect the flow rate of the foam flowing in the foam feed pipe 1 and transmit the data to the fire truck's on-board display device. Personnel can control the opening and closing angle of the electric ball valve 3 through the manual operation panel 5 to control the amount of foam entering the venturi tube 4, which facilitates the mixing of foam and water with the glass.

[0038] After the device is installed on the vehicle-mounted fire pump, the hook 206 is hooked onto the pipeline of the vehicle-mounted fire pump. The hook 206 is rotated and moved through the internal threaded sleeve 205. The distance between the hook 206 and the first sleeve 201 is adjusted. After the long screw 204 and the internal threaded sleeve 205 are tightened, the connection stability between the foam feed pipe 1 and the vehicle-mounted fire pump can be improved. The anti-slip sleeve 207 is set to prevent slipping and make it convenient for personnel to hold and rotate the internal threaded sleeve 205.
