Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0045] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0046] In this embodiment:

[0047] Reference Figure 1-3 As shown, a preferred embodiment of the present invention is provided.

[0048] The emergency power supply with a protective function of this embodiment includes a protective shell 1 and a chassis 2, wherein a battery assembly 3 and a control panel 4 are respectively installed inside the protective shell 1, and ventilation plates 13 are arranged on both sides of the protective shell 1 between the battery assembly 3 and the control panel 4, and the chassis 2 includes a track wheel 22 driven by a drive motor 21, and the battery assembly 3 includes a mounting frame 31 and a lock plate 35 installed in the protective shell 1, and a plurality of battery rails 32 are obliquely installed on the mounting frame 31, and a battery 34 is slidably installed on the battery rails 32, and the oblique upward arrangement along the travel direction can effectively avoid the situation where the battery 34 moves due to inertia when the emergency power supply stops suddenly during travel;

[0049] The lock plate 35 is provided with a drive box 38 and an induced draft fan 351 corresponding to the battery 34. The drive box 38 is used to lock the battery 34. The drive box 38 is also used to detect the temperature of the battery 34 introduced by the induced draft fan 351 and eject the overheated battery 34 out of the protective housing 1, while driving the induced draft fan 351 to supply air in the reverse direction to prevent the fire from being led back into the protective housing 1 after the overheated battery 34 burns.

[0050] Among them, the control panel 4 includes a PLC of model S4-400, which is electrically connected to each electrical component and integrated with a switch knob and an interface. It sends instructions to the PLC through the switch knob and the interface, and uses PLC programming to achieve real-time control of each electrical component.

[0051] Furthermore, a battery cover 11 is hinged on the top of one side of the protective shell 1 close to the battery assembly 3, and an operation cover 12 is hinged on the top of one side of the protective shell 1 close to the control panel 4, and triangular locks for locking the battery cover 11 and the operation cover 12 are provided on both sides of the protective shell 1, so that the battery cover 11 and the operation cover 12 can be conveniently opened and closed by the triangular locks.

[0052] In addition, the battery rail 32 is inclined toward the battery cover 11, and the end of the battery 34 passes through and extends to the outside of the battery cover 11, so that the battery 34 can be directly ejected from the battery cover 11 after overheating, thereby preventing the battery 34 from burning and igniting other batteries 34 in the protective shell 1, thereby achieving a protective effect. A blocking piece 341 is provided above one end of the battery 34 located outside the battery cover 11, and the blocking piece 341 is at the same height as the butterfly mounting piece 33. In order to prevent the butterfly mounting piece 33 and the extrusion plate 331 from being blocked and unable to eject when the battery 34 ejects, a certain through groove needs to be opened on the battery cover 11 above the battery 34, and the blocking piece 341 is used to cover the through groove. A handle 342 is also installed at the end of the battery 34 to facilitate loading and unloading of the battery 34.

[0053] In order to realize the installation of the above-mentioned battery 34, refer to the attached Figure 4-5 As shown, a guide rod 36 is installed on one side of the lock plate 35 close to the battery slide rail 32, and a first spring 37 is sleeved on the outside of the guide rod 36. A butterfly-shaped mounting piece 33 is provided on the top of the battery 34. The battery 34 is fixed with two sets of extrusion plates 331 sleeved on the outside of the guide rod 36 by bolts of the butterfly-shaped mounting piece 33. The extrusion plate 331 is provided with an extrusion plate 333 that abuts against the first spring 37. When installing the battery 34, the butterfly-shaped mounting piece 33 on the top of the battery 34 is fixed above the extrusion plate 331, and the battery 34 is moved along the battery slide rail 32 toward the anti-locking device. The battery 34 is pushed into the protective shell 1, and the end of the extrusion plate 331 is connected to two groups of hooks 332 through a rotating shaft. The surface of the lock plate 35 is provided with a slot 352 corresponding to the hook 332, and an inclined surface is provided below the end of the hook 332. When the hook 332 moves with the battery 34 on the battery slide rail 32 to the slot 352 of the lock plate 35, due to the existence of the inclined surface of the hook 332, the end of the hook 332 will be lifted up and buckled on the slot 352. At this time, the first spring 37 is in a compressed state, and the battery 34 is fixed to the inside of the protective shell 1 through the hook 332.

[0054] Refer to the attached Figure 6-7As shown, a T-shaped guide groove 381 is provided in the drive box 38, and a vertically connected guide block 382 and a push rod 383 are slidably installed in the guide groove 381 along the vertical direction. The two ends of the push rod 383 extend to the outside of the drive box 38 respectively, and the end of the push rod 383 is provided with an inclined surface facing the side of the battery 34. A heat conducting plate 384 is provided in the drive box 38, and the heat conducting plate 384 extends to the side of the drive box 38 facing the battery 34, and an air bag 3841 is provided at the top of the heat conducting plate 384 corresponding to the guide block 382. Under the action of the induced draft fan 351, the external air of the protective shell 1 is introduced into the interior from the side of the battery cover 11, which can dissipate heat for the battery 34 on the one hand, and can carry the heat of the battery 34 to the heat conducting plate 384 extending to the outside of the drive box 38 on the other hand. The heat conducting plate 384 will transfer the heat to the air bag 3841, and the air bag 3841 inside The airbag 3841 is filled with shape memory alloy + inert gas. The shape memory alloy acts as a sensing element and bends with temperature changes, driving the airbag 3841 to expand and contract. The airbag 3841 is filled with inert gas such as nitrogen, which can better conduct the temperature to the shape memory alloy and also has the effect of thermal expansion and contraction. During the thermal expansion of the airbag 3841, the guide block 382 will be pushed upward, so that the push rod 383 slides upward in the guide groove 381, and then the hook 332 is pushed upward along the shaft connection until it is disengaged from the slot 352 and is reset and pushed out by the first spring 37, and the heat-generating battery 34 is pushed out to the outside of the protective shell 1 through the battery slide rail 32, and at the same time, all the induced draft fans 351 are driven in the reverse direction to draw air from the ventilation plate 13 and blown out in the direction of the overheated battery 34, so as to prevent the fire of the battery 34 from spreading to the inside of the protective shell 1 with the flow of air after spontaneous combustion, and effectively avoid damage to other batteries 34.

[0055] It is worth noting that the inner side of the drive box 38 is also telescopically provided with a sleeve rod 387, and the end of the sleeve rod 387 is installed with a power-on plate 385 extending to the outside of the drive box 38, and the surface of the power-on plate 385 is provided with two power-on conductive pieces 3851, and the two power-on conductive pieces 3851 are respectively connected to the first contact pieces 3852 extending to the inside of the two sides of the drive box 38, and the end of the battery 34 is provided with two battery conductive pieces 343, and the two battery conductive pieces 343 are connected to the two power-on conductive pieces 3851. The guide piece 3851 abuts against the driving box 38, and the two sides of the driving box 38 are provided with a terminal head 386, and the terminal head 386 is provided with a terminal piece 3861. The terminal pieces 3861 between the driving boxes 38 are connected in series through the wire 353. When the battery guide piece 343 of the battery 34 abuts against the power-on guide piece 3851, the first contact piece 3852 can contact the terminal head 386, thereby cooperating with the terminal piece 3861 and the wire 353 to realize the power-on series state between the batteries 34;

[0056] When the battery 34 is pushed into the protective shell 1, the battery guide 343 will conflict with the power-on guide 3851, and the battery 34 continues to push into the protective shell 1 and fix the hook 332, the second spring 3872 will be compressed, and the first contact piece 3852 will conflict with the terminal head 386, and the second spring 3872 will be compressed. When the battery 34 with abnormal temperature is pushed out of the protective shell 1, the first contact piece 3852 will be separated from the terminal head 386, and the inner wall of one side of the drive box 38 is provided with a pressure rod 3871 extending into the sleeve rod 387, and the sleeve rod 387 A second spring 3872 is also provided inside, and the end of the second spring 3872 contacts the end of the pressure rod 3871. A battery rack 388 is fixed to the outside of the sleeve rod 387, and a second contact piece 3881 is also provided at the end of the battery rack 388. When the second spring 3872 is reset, it pushes the battery rack 388 outside the sleeve rod 387 to move toward the terminal head 386, so that the first contact piece 3852 is separated from the terminal head 386, and the second contact piece 3881 contacts the terminal head 386, ensuring that the circuit between other batteries 34 is not disconnected and continues to provide emergency power supply for the equipment.

[0057] The emergency power supply makes the installation, replacement and maintenance of the battery 34 simple and efficient through the inclined battery slide rail 32 and the locking mechanism, and can also prevent the battery 34 from moving due to inertia when the equipment stops suddenly. The temperature of the battery 34 can be monitored in real time through the temperature detection system composed of the heat conduction plate 384, the air bag 3841 and the shape memory alloy in the drive box 38. When the battery 34 is detected to be overheated, the top rod 383 and the hook 332 work together to automatically eject the overheated battery 34 out of the casing. The design of the ventilation plate 13 and the induced draft fan 351 not only provides daily heat dissipation, but also can change the wind direction in an emergency to prevent the fire from spreading inward, thereby effectively preventing the spread of fire.

[0058] The emergency power supply, through the settings of the power-on board 385, the first contact piece 3852, the second contact piece 3881 and the terminal head 386, can automatically switch the circuit even when the abnormal battery 34 is ejected, to ensure that other batteries 34 continue to supply power and maintain the continuous operation of the system.
