[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] Please refer to Figure 1 , a power generation cabin 10 for emergency rescue and disaster relief, which includes: a generator 100, a base 200 and a plurality of floating brackets 300.

[0040] Please refer to Figure 1 , the generator 100 is arranged on the base 200, and a plurality of telescopic brackets 110 are arranged on the outer wall of the generator 100, and a plurality of floating brackets 300 are arranged on the base 200 at intervals.

[0041] When transporting the power generation cabin 10 for emergency rescue and disaster relief, first start the telescopic brackets 110. When the telescopic brackets 110 extend, the generator 100 together with the base 200 will be lifted. The driver reverses the vehicle and moves the vehicle shelf under the base 200. In this way, when the telescopic brackets 110 contract, the power generation cabin 10 for emergency rescue and disaster relief will fall onto the vehicle shelf. When unloading, just start the telescopic brackets 110 again. After the generator 100 and the base 200 are lifted, the vehicle can be driven away. Forklift assistance is not required during the loading and unloading process, effectively reducing the transportation time of the power generation cabin 10 for emergency rescue and disaster relief. Preferably, an operation panel 120 is arranged on the generator 100.

[0042] Please refer to Figure 2 , Figure 3 and Figure 4, the floating bracket 300 includes a cylinder block 310, a foot cup 320, a piston rod 330, a pin 340, a rocker 350, and an operating rod 360 that matches the rocker 350. The cylinder block 310 is provided with a piston chamber 311, a liquid storage chamber 312 and a telescopic chamber 313 that communicate with the piston chamber 311. A partition 314 is provided between the liquid storage chamber 312 and the telescopic chamber 313. Hydraulic oil 11 is stored in the liquid storage chamber 312. The foot cup 320 penetrates the telescopic chamber 313. The rocker 350 is rotatably arranged on the cylinder block 310. The piston rod 330 is connected to the rocker 350. The piston rod 330 penetrates the piston chamber 311. The pin 340 is slidably arranged on the cylinder block 310. The pin 340 passes through the partition 314 and extends into the liquid storage chamber 312. A pressure relief channel 341 is provided at the position of the pin 340 in the liquid storage chamber 312. A lock nut 342 is provided on the pin 340. A limit groove 315 that matches the lock nut 342 is provided on the outer wall of the cylinder block 310 (as Figure 8 shown);

[0043] Please refer to Figure 4 and Figure 5 , check valves 370 are provided at the positions where the piston chamber 311 communicates with the liquid storage chamber 312 and where the piston chamber 311 communicates with the telescopic chamber 313. The orientations of the two check valves 370 are opposite. Specifically, the check valve 370 at the position where the piston chamber 311 communicates with the liquid storage chamber 312 faces the piston chamber 311, and the hydraulic oil 11 can only flow from the liquid storage chamber 312 into the piston chamber 311; the check valve 370 at the position where the piston chamber 311 communicates with the telescopic chamber 313 faces the telescopic chamber 313, and the hydraulic oil 11 can only flow from the piston chamber 311 into the telescopic chamber 313.

[0044] The foot cup 320 has the ability to expand and contract. After transporting the power generation cabin 10 for emergency rescue and disaster relief to the destination, the extension lengths of the respective foot cups 320 can be adjusted according to the on-site terrain, so that the generator 100 is evenly erected in the rescue site to provide electrical energy for the rescue equipment.

[0045] Please refer to Figures 4 to 10 , the process of adjusting the extension length of the foot cup 320 is as follows:

[0046] After placing the power generation cabin 10 for emergency rescue and disaster relief on the ground, determine the foot cup 320 that needs to be adjusted in length according to the inclination of the generator 100;

[0047] The method of extending the foot cup 320 is as follows:

[0048] Pick up the operating rod 360, dock the operating rod 360 with the rocker 350 at the position of the target foot cup 320, and swing the operating rod 360 up and down. At this time, the rocker 350 drives the piston rod 330 to perform a piston movement in the piston chamber 311. Specifically, please refer to Figure 4, when the piston rod 330 moves upward, the space enclosed by the end of the piston rod 330 and the piston chamber 311 becomes larger, the pressure becomes lower, and the hydraulic oil 11 in the liquid storage chamber 312 enters the piston chamber 311 through the one-way valve 370 (as Figure 6 shown); please refer to Figure 5 , when the piston rod 330 is pressed down, the space enclosed by the end of the piston rod 330 and the piston chamber 311 shrinks, the pressure increases, and the hydraulic oil 11 in the piston chamber 311 is pushed into the telescopic chamber 313 (as Figure 7 shown). The hydraulic oil 11 entering the telescopic chamber 313 pushes the foot cup 320, causing the foot cup 320 to extend. And because a one-way valve 370 is provided at the position where the piston chamber 311 communicates with the telescopic chamber 313, it can prevent the hydraulic oil 11 from flowing back, and can prevent the foot cup 320 from retracting due to the pressure of the generator 100.

[0049] The method to retract the foot cup 320 is as follows:

[0050] When it is necessary to retract the foot cup 320, first toggle the latch 340 to make the lock cap 342 leave the limit groove 315 (as Figure 9 shown), then apply a pulling force to drag the latch 340 to make the pressure relief channel 341 communicate the liquid storage chamber 312 and the telescopic chamber 313 (as Figure 10 shown). Under the gravity of the generator 100, the foot cup 320 squeezes the hydraulic oil 11 in the telescopic chamber 313, causing the hydraulic oil 11 to flow back to the liquid storage chamber 312 through the pressure relief channel 341; push the latch 340 so that the part where the pressure relief channel 341 is located is completely immersed in the partition 314, and then the liquid storage chamber 312 and the telescopic chamber 313 are separated again (as Figure 4 shown). The hydraulic oil 11 cannot flow back, so the foot cup 320 stops contracting. Rotate the latch 340 to make the lock cap 342 re-enter the limit groove 315 (as Figure 8 shown), and complete the locking of the latch 340.

[0051] It should be emphasized that both the liquid storage chamber 312 and the telescopic chamber 313 communicate with the piston chamber 311, and the liquid storage chamber 312 and the telescopic chamber 313 are separated by a partition 314. Check valves 370 are provided at the positions where the liquid storage chamber 312 and the telescopic chamber 313 communicate with the piston chamber 311, and the orientations of the two check valves 370 are opposite. In this way, the negative pressure generated when the piston rod 330 moves away from the piston chamber 311 can draw the hydraulic oil 11 in the liquid storage chamber 312 into the piston chamber 311. When the piston rod 330 extends into the piston chamber 311, it compresses the hydraulic oil 11 and causes it to enter the telescopic chamber 313. The hydraulic oil 11 entering the telescopic chamber 313 pushes the foot cup 320 to extend. A pressure relief channel 341 is provided in the part of the plug 340 extending into the liquid storage chamber 312. Applying a pulling force to drag the plug 340 can make the pressure relief channel 341 communicate the telescopic chamber 313 and the liquid storage chamber 312, allowing the hydraulic oil 11 in the telescopic chamber 313 to flow back into the liquid storage chamber 312 and making the foot cup 320 retract. The piston rod 330 and the two check valves 370 cooperate to extend the foot cup 320, while the plug 340 and the partition 314 cooperate to contract the foot cup 320, enabling the foot cup 320 to expand and contract according to the ground undulation, thereby improving the adaptability of the power generation cabin 10 for emergency rescue and disaster relief to complex road conditions.

[0052] Please refer to Figure 6 and Figure 7 , in one embodiment, the check valve 370 includes a threaded cylinder 371 and a steel ball 372. A liquid inlet hole 371a and a liquid outlet hole 371b that communicate with each other are formed in the threaded cylinder 371. A funnel-shaped blocking portion 371c is provided between the liquid inlet hole 371a and the liquid outlet hole 371b, and the steel ball 372 is located in the liquid outlet hole 371b. The diameter of the liquid inlet hole 371a is smaller than that of the liquid outlet hole 371b, and the diameter of the liquid inlet hole 371a is smaller than the diameter of the steel ball 372. The check valve 370 and the piston rod 330 cooperate to control the flow of the hydraulic oil 11 as follows:

[0053] As Figure 6 shown, when the piston rod 330 moves upward, the pressure in the piston chamber 311 decreases, driving the hydraulic oil 11 to flow toward the piston chamber 311. Consequently, the steel ball 372 displaces toward the side where the piston chamber 311 is located (the right side in the figure). The orientations of the two check valves 370 are opposite. In the upper check valve 370, the steel ball 372 moves toward the liquid outlet hole 371b, and the liquid inlet hole 371a is not blocked, so the hydraulic oil 11 in the liquid storage chamber 312 can enter the piston chamber 311. In the lower check valve 370, the steel ball 372 moves toward the liquid inlet hole 371a and abuts against the funnel-shaped blocking portion 371c. Since the liquid inlet hole 371a is blocked, the hydraulic oil 11 in the telescopic chamber 313 cannot enter the piston chamber 311.

[0054] As Figure 7As shown, when the piston rod 330 presses down, the pressure in the piston chamber 311 increases, driving the hydraulic oil 11 to leave the piston chamber 311. The steel ball 372 moves away from the piston chamber 311 (to the left in the figure). In the upper one-way valve 370, the steel ball 372 moves towards the liquid inlet hole 371a and abuts against the funnel blocking portion 371c. Since the liquid inlet hole 371a is blocked, the hydraulic oil 11 in the piston chamber 311 cannot enter the liquid storage chamber 312. In the lower one-way valve 370, the steel ball 372 moves towards the liquid outlet hole 371b, and the liquid inlet hole 371a is not blocked, so the hydraulic oil 11 in the piston chamber 311 enters the telescopic chamber 313.

[0055] Please refer to Figure 2 and Figure 3 , preferably, a docking hole 351 is provided on the rocker 350, and a plugging portion is provided on the operating rod 360. The docking hole 351 is used to accommodate the plugging portion, and an avoidance hole 21 is provided on the base 200 near the rocker 350. When it is necessary to drive the foot cup 320 to extend, the operating rod 360 is passed through the avoidance hole 21, and the plugging portion on the operating rod 360 is inserted into the docking hole 351, then the rocker 350 can be swung.

[0056] Please refer to Figure 1 , in one embodiment, a storage portion 210 and a hinged door 220 are provided on the base 200. The storage portion 210 can be used to store maintenance tools, cables, etc., and the operating rod 360 is stored in the storage portion 210.

[0057] Please refer to Figure 3 and Figure 4 , preferably, a sleeve 316 for accommodating the foot cup 320 is provided on the cylinder block 310.

[0058] The above power generation cabin 10 for disaster relief and rescue has the following advantages:

[0059] 1. The telescopic support 110 can lift the whole power generation cabin, which is convenient for loading and thus facilitates handling;

[0060] 2. The swing of the rocker 350 can inject the hydraulic oil 11 in the liquid storage chamber 312 into the telescopic chamber 313, driving the foot cup 320 to extend. Unlocking the latch 340 can also allow the hydraulic oil 11 to flow back into the liquid storage chamber 312, enabling the foot cup 320 to have the ability to be telescopic while bearing the weight of the generator 100, and the extended length of each foot cup 320 can be flexibly adjusted to adapt to the uneven ground;

[0061] 3. By driving the rocker 350 to swing with the operating rod 360 and using the cooperation of two one-way valves 370 to prevent the hydraulic oil 11 from flowing back, the adjustment process of the foot cup 320 is simple and labor-saving.

[0062] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
