[0032] Embodiment 1

[0033] In order to solve the technical problems in the background technology, a dry powder and foam combined fire truck is provided as follows:

[0034] Combination Figure 1-Figure 11 As shown, a dry powder and foam combined fire truck provided by the present invention comprises a vehicle body 1, a vehicle compartment 2 is fixedly mounted on the vehicle body 1, a foam component 7 and a dry powder component 9 are respectively fixedly mounted inside the vehicle compartment 2, two groups of storage chambers 22 are arranged on the front of the vehicle compartment 2, an extraction component 8 is assembled inside the storage chamber 22, a transfer component 6 is installed on the front limit of the extraction component 8, two groups of high-position fire fighting mechanisms 4 are docked and mounted on the top of the vehicle compartment 2, a transfer component 3 is fixedly mounted on the vehicle compartment 2 between the high-position fire fighting mechanisms 4, and the transfer component 3 is used to operate the high-position fire fighting mechanisms 4;

[0035] During the period, the foam component 7 and the dry powder component 9 in the car 2 enable the fire truck to switch the fire-fighting medium between foam and dry powder according to the actual fire-fighting needs to meet the operation needs of the fire truck. The extraction component 8 in the storage room 22 cooperates with the adapter component 6 to realize the automatic storage and lowering of the adapter component 6, and the adapter component 6 is used to realize the auxiliary operation of the firefighters. When the personnel are working, the adapter component 6 can be used as a blocking structure to assist the personnel in protective advancement during the firefighting period, thereby improving the safety of the personnel during the operation. The high-position fire-fighting mechanism 4 enables the fire truck to cope with the fire-fighting operation at a high position, avoiding the influence of insufficient fire-fighting height or obstacles that make it difficult to better cover the ground, and by combining with the adapter component 6, the high-position fire-fighting mechanism 4 can be disassembled from the fire truck and can be used for mobile fire-fighting operations in a small space environment. This effectively avoids the limitations of the fire truck due to its large size. The transfer component 3 enables the high-position fire-fighting mechanism 4 to be automatically combined with the fire truck and the adapter component 6, without the need for personnel to disassemble and carry it, which is more efficient and convenient during the operation.

[0036] The transfer assembly 3 includes an extension component 31 and a clamping component 32; the high-position fire-fighting mechanism 4 includes a driving assembly 41, a first scissor-type telescopic frame 42, and a fire-fighting assembly 43. The driving assembly 41 is fixedly installed on the top of the carriage 2, the first scissor-type telescopic frame 42 is assembled on the top of the driving assembly 41, and the fire-fighting assembly 43 is docked and installed on the top of the first scissor-type telescopic frame 42. The extension component 31 is fixedly installed on the carriage 2 between the driving assemblies 41, and the clamping component 32 is docked and installed on the driving end of the extension component 31; the adapter assembly 6 includes a protective seat plate 61 and a fire-proof component 62, and the extraction assembly 8 includes a positioning component 81 , a lifting component 82, the interior of the storage chamber 22 is equipped with a lifting component 82, the upgraded end of the lifting component 82 is docked with a positioning component 81, the lifting component 82 is docked with a protective seat plate 61 through the positioning component 81, the front of the protective seat plate 61 is provided with a mounting groove 615, and the protective seat plate 61 is docked with a fireproof component 62 through the mounting groove 615, the bottom of the protective seat plate 61 is docked with two groups of lower wheels 613, and the top is docked with an upper wheel 614, both sides of the inside of the protective seat plate 61 are fixedly installed with operating handles 612, and both sides of the protective seat plate 61 are provided with two groups of positioning holes 611.

[0037] During this period, when it is necessary to perform high-position operations, personnel can climb onto the roof and enter the fire-fighting component 43, and drive the first scissor-type telescopic frame 42 by starting the driving component 41, so that the first scissor-type telescopic frame 42 lifts the fire-fighting component 43 to the required operating height, and then delivers the fire-fighting medium into the fire-fighting component 43, and personnel perform corresponding operations. When the fire-fighting intensity on the ground is high, the protective seat plate 61 can be put into operation, and the positioning component 81 and the lifting component 82 cooperate with each other to drive the front end of the protective seat plate 61 to extend, and push it out synchronously, and release the positioning after lowering it. The personnel then assemble the fire-proof component 62 with the protective seat plate 61, and then the personnel can operate the protective seat plate 61 by operating the handle 612. During this period, the fire-fighting personnel can stand behind the protective seat plate 61 to promote fire-fighting. When the fire-proof component 62 is damaged during the operation, it can be disassembled and replaced when waiting for the next operation.

[0038] When the fire truck encounters a special environment and cannot enter, the personnel can lower the high-position fire-fighting mechanism 4. First, the high-position fire-fighting mechanism 4 is clamped by the clamping component 32, and then the high-position fire-fighting mechanism 4 is lowered by adjusting and cooperating with the extension component 31. When lowering, it is necessary to ensure that the high-position fire-fighting mechanism 4 is docked with the mounting groove 615 in the protective seat plate 61. At this time, the protective seat plate 61 is in a horizontal state, and the lower wheel 613 and the upper wheel 614 are in contact with the ground to achieve rolling support for the protective seat plate 61. When operating, it is in a vertical state. By positioning the high-position fire-fighting mechanism 4 and the protective seat plate 61, the personnel can push the protective seat plate 61, thereby driving the high-position fire-fighting mechanism 4 to move to a specific fire-fighting area.
