All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In addition, "a plurality of" means two or more.
See fig. 1-7.
In the forest fire control vehicle provided by the invention, the places which are not marked with the driving mode are all hydraulically driven.
The invention provides a forest fire-extinguishing vehicle, comprising:
the vehicle body 1 with a carriage 11 is provided with a power driving mechanism 2, a speed increasing mechanism 3, a pumping mechanism 4, a pump station 5 and an oil pipe winch 6 from back to front in the carriage 11, a floating boat pump storage chamber 7 is arranged below the carriage 11 and used for storing a floating boat pump, and a water pipe placing frame (not shown in the figure) is arranged at one side of the carriage 11 corresponding to the power driving mechanism 2 and used for storing a coiled water pipe. The power driving mechanism 2 is provided with an output shaft connected with the speed increasing mechanism 3 and transmits the rotating speed and the torque to the speed increasing mechanism 3; the speed increasing mechanism 3 is connected to the pumping mechanism 4, and is used for amplifying the rotation speed transmitted by the power driving mechanism 2, so as to improve the pumping capacity (the pumping capacity comprises the lift and the flow rate) of the pumping mechanism 4.
In the concrete implementation, when facing forest fire, fire fighters drive the vehicle to the water taking place closest to the fire source, then take out the floating boat pump from the floating boat pump storage chamber 7 and move the floating boat pump to the water surface, one end of an oil pipe on the oil pipe winch 6 is connected with the pump station 5, the other end is connected with the floating boat pump, and the water outlet of the floating boat pump is connected with the water inlet of the pumping mechanism 4 through a water pipe; and meanwhile, the water pipe on the water pipe placing frame is taken down, one end of the water pipe is connected with the water outlet of the pumping mechanism 4, and the other end of the water pipe reaches the fire place in a splicing mode with the rest water pipes. After the early work is completed, starting a pump station 5, wherein the pump station 5 works to provide power for the floating boat pump through an oil pipe; meanwhile, the pumping mechanism 4 is driven by the power driving mechanism 2 and the speed increasing mechanism 3, the water inlet of the pumping mechanism generates suction force, the suction force and the buoyancy pump are combined in a multistage pumping mode, the pumping effect is improved, and the water is pumped to a fire place. The power of the pump station 5 may be electric power or may be obtained directly from the vehicle body 1 by using a power take-off. The power take-off and the power take-off method thereof are common knowledge of those skilled in the art, and therefore are not described herein.
In order to ensure that the forest fire extinguishing vehicle has enough pumping capacity, the torque output by the power driving mechanism 2 needs to be increased, and then the power driving mechanism 2 with a larger size needs to be used, and in order to save space, the power driving mechanism 2, the speed increasing mechanism 3, the pumping mechanism 4, the pump station 5 and the oil pipe winch 6 are sequentially arranged, so that the compactness in the carriage 11 is improved. The winding grooves on the oil pipe winding disc 6 face to two sides of the width direction of the carriage 11, so that the oil pipe can be conveniently taken out from the oil pipe winding disc 6 from any side of the width direction of the carriage 11; meanwhile, the arrangement mode of the oil pipe winch 6 can reduce the space occupied by the oil pipe winch in the length direction of the carriage 11, so that the length of the carriage 11 can be designed to be shorter.
This application through setting up the water pipe rack in the one side of power drive mechanism 2, when utilizing the space of carriage 11 inside as far as, can not lengthen the length of carriage 11, reasonable in design.
The prior art buoyancy pump is typically disposed inside the cabin 11, and the present application removes the buoyancy pump from the cabin 11 in order to reduce the length of the cabin 11. Although there are also floating boat pumps in the prior art which are arranged outside the carriage, for example, the chinese patent application No. CN201710058083.3 discloses a semi-submersible floating boat pump structure for an automatic water-guiding fire engine, as can be seen from fig. 4 of the specification, the floating boat pump is arranged at the top of the carriage, and the floating boat pump is lifted off the carriage by a crane arm arranged at the tail of the carriage. However, the boom provided in this patent not only aggravates the overall weight of the vehicle body, but also lengthens the length of the vehicle body, which is not consistent with the original purpose of the present application, and at the same time, in a forest environment, there is a lack of space for the normal lifting and rotating operation of the boom, and the boom is provided with a slight rib. According to the floating boat pump storage device, the floating boat pump storage chamber is arranged below the carriage, the floating boat pump is stored in the storage chamber, corresponding work can be completed only by using manpower when the floating boat pump is stored and taken out, and the purpose of reducing the length of the carriage is achieved without additionally arranging a lifting arm.
