Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, specifically to a multifunctional foam transfer device. Background Technology

[0002] In the handling of large-scale chemical fires, a large amount of foam is used. This is specifically achieved by transferring foam concentrate from foam tanks to foam trucks or other foam containers using a transfer pump. The foam transfer pump is a specialized device used by fire brigades to add and transport foam concentrate to their vehicles. It has its own gasoline engine, a baked-on paint finish, and its own power supply. It features one-button start, eliminating the need for an external power source. This pump is compact, has a large flow rate, operates stably with low noise, is highly mobile, and easy to use. It is primarily used for adding and transferring foam concentrate during and after firefighting operations, and can also be used to transport other viscous liquids.

[0003] However, in the actual process of foam transportation, the foam transfer pump is relatively heavy. When it needs to be moved, it is carried manually, which increases the labor force. Moreover, firefighters transport equipment to the scene by hand, which not only increases the labor force of firefighters, but also cannot ensure that the equipment can reach the rescue scene quickly. Therefore, there is an urgent need for a multi-functional foam transfer device that can both facilitate the movement of foam transfer pumps and quickly move firefighting equipment to designated locations. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a multifunctional foam transfer device that not only facilitates foam transfer but also enables rapid transport of firefighting equipment to designated areas and provides lighting for field rescue operations.

The handlebars are rotatably mounted on the frame by a support rod, and the end of the support rod passes through the frame and is connected to the front connecting rod.

[0007] Furthermore, the rear connecting rod is provided with a driven chain sprocket, and the other output end of the engine is provided with an active fuel-saving tooth, which is connected to the driven chain sprocket by a chain.

[0008] Furthermore, a chain tensioner that meshes with the chain is provided on the frame and located between the active oil-saving tooth and the driven sprocket.

[0009] Furthermore, a brake disc is provided on the rear connecting rod, and a brake lever is provided on the handlebar.

[0010] Furthermore, a toolbox is provided on the frame.

[0011] Furthermore, the frame is located above the explosion-proof transfer pump and a seat is mounted on it via a housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the overall structure of this utility model is compact, which can facilitate the delivery of fire-fighting equipment to some space-constrained areas; the engine provides a power source for the vehicle body and explosion-proof transfer pump, and at the same time, with the help of the generator, battery and other structures, it provides power and power sockets for the lighting.

[0018] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a multifunctional foam transfer device, including a vehicle body 1, an oil tank 3 mounted on the vehicle body 1, an engine 4, a generator and a power take-off 2 connected to the engine 4, a trailer bed 5, an explosion-proof transfer pump 6, and a battery 14. The explosion-proof transfer pump 6 and the battery 14 are mounted on the vehicle body 1 by cable ties and bolts. The generator is connected to the battery 14 through a rectifier. The output end of the battery 14 is connected to a power socket 15 and a cooling fan 16. The power socket 15 can provide a power port for a lighting lamp for use during field rescue. The lighting can use 480W 960 LEDs, with an effective lighting distance of 500 square meters; the cooling fan 16 is used to cool the generator; the front of the vehicle body 1 is equipped with a headlight 8, which is connected to the battery; the trailer 5 is installed at the rear of the vehicle body 1 via a tie rod 7, one end of the tie rod 7 is connected to the rear of the vehicle body 1 via a pin, which facilitates the installation and removal of the trailer 5; the power take-off 2 is a dual-output shaft power take-off, the input shaft end of the explosion-proof transfer pump 6 is connected to one output shaft end of the power take-off via a coupling, and the other output end of the power take-off 2 provides a power source for the drive of the vehicle body 1.

[0020] The vehicle body 1 includes a frame 101, two front wheels 102, two rear wheels 103, and handlebars 104. The two rear wheels 103 are connected to each other by a rear connecting rod 105 and mounted on the bottom of the frame 101. The two front wheels 102 are connected to each other by a front connecting rod 109 and mounted on the bottom of the frame 101. The handlebars 104 are rotatably mounted on the frame 101 by a support rod 110. A headlight 8 is installed at the front end of the handlebars 104. The headlight 8 is connected to the battery 14 by a wire. The end of the support rod 110 passes through the frame 101 and is connected to the front connecting rod 109.

[0021] like Figure 1-4As shown, in this embodiment, the handlebars 104 are also equipped with an ignition switch for starting the engine 4 with a key, a switch button for controlling the headlight 8, a horn button, and a horn.

By rotating the handlebars 104, the two front wheels 102 are deflected, thereby changing the direction of movement of the vehicle 1. During nighttime rescues, it is generally necessary to connect to household electricity for lighting. However, in field rescues, it is difficult to find a power source at the rescue site. Therefore, in this embodiment, a battery 14 is installed on the frame 101. The battery 14 serves as the headlight 8, external lighting, and a diffuser. The hot air fan 16 provides power, and the external lighting is suitable for providing power for nighttime field rescue. In this embodiment, the engine 4 provides mechanical energy and indirectly provides electrical energy to drive the vehicle body 1 to move, control the explosion-proof transfer pump 6 to start, and provide power to the vehicle lights 8, external lighting, and cooling fan 16, etc. The explosion-proof transfer pump 6 can not only be used to transport foam, but also to pump water and other liquids. In this embodiment, the vehicle body 1 adopts a rear-drive mode, and the direction of the two front wheels 102 is controlled by turning the handlebars 104 to achieve the purpose of steering. The trailer 5 can transport goods, and the vehicle lights 8 ensure illumination during the journey. The multifunctional foam transfer device provided by this utility model has the advantages of compact structure and small footprint, which can meet the needs of transporting goods in some space-constrained areas, enabling fire-fighting equipment to reach the scene quickly, ensuring timely equipment arrival, and rapid rescue.

[0022] The rear connecting rod 105 is provided with a driven chain 106, and the other output end of the power take-off 2 is provided with an active oil-saving tooth 107. The active oil-saving tooth 107 and the driven chain 106 are connected by a chain 108.

[0023] like Figure 1 , 3 As shown in Figure 4, the generator 4 is started and converted into mechanical energy, which drives the active oil-saving gear 107 to rotate through the power take-off unit 2. Under the action of the chain 108 and the driven chain 106, the rear connecting rod 105 will rotate, and the rear connecting rod 105 will drive the two rear wheels 103 to rotate, thereby realizing the movement of the vehicle 1 by rear drive.

[0024] A chain tensioner 111, which meshes with the chain 108, is provided on the frame 101 and located between the active oil-saving tooth 107 and the driven sprocket 106.

[0025] like Figure 4 As shown, the tension of the chain 108 can be increased by the chain tensioner 111, thereby improving the transmission effect.

[0026] The rear connecting rod 105 is equipped with a brake disc 9, and the handlebar 104 is equipped with a brake lever 10. The brake lever 10 and the brake disc 9 are connected by a brake cable.

[0028] The frame 101 is equipped with a toolbox 11; the frame 101 is located above the explosion-proof transfer pump 6 and is mounted with a seat 13 through a housing 12. The inlet and outlet of the explosion-proof infusion pump 4 are exposed through the housing 12 for easy connection to pipes.

[0029] like Figure 4 As shown, the toolbox 11 is used to store tools, and the person sits on the seat 13 for easy control of the handlebars 104 and the brakes.

[0030] Operating principle: When only foam needs to be transferred, the trailer 5 can be disassembled first. Firefighters sit on the seat 13 and can use the start lever and ignition switch, then hold the handle 104 to change the orientation of the vehicle body 1 according to the actual situation. At the same time, they turn the handle to drive the vehicle body 1 to the required location. After arriving at the location, the foam transfer pipes can be installed at the inlet and outlet ends of the explosion-proof transfer pump 6 to realize the foam transfer function. When it is necessary to transport fire-fighting equipment, the trailer 5 can be installed on the vehicle body 1 through the pin, and then the fire-fighting equipment to be transported can be placed in the trailer 5.
