It is equipped with a battery box inside, which is the energy source and main power supply of the inspection robot dog.

[0003] At present, the battery boxes of patrol robot dogs are installed inside the torso to reduce the external space occupied and do not affect the normal walking of the robot dog. However, the battery box will generate a certain amount of heat when it is in operation. If this heat cannot be dissipated in time, it may cause battery performance to decline, shorten its life, and even cause safety accidents. Therefore, in order to avoid excessive temperature affecting battery performance, or thermal runaway or battery explosion due to overheating, the battery box needs to be cooled in time.

When the battery box inside the robot dog body generates heat during operation, the heat will first be guided to a number of heat-conducting plates by a heat-conducting shell wrapped in the outside of the battery box, and then the heat will be driven by a transmission mechanism to rotate a number of fan blades, thereby forming flowing air between the several heat-conducting plates, thereby further improving the heat dissipation speed, thereby preventing the battery box inside the robot dog body from overheating, causing thermal runaway or even battery explosion.

[0005] The utility model provides the following technical solutions: a battery box protection mechanism for an inspection robot, comprising a heat-conducting shell installed inside a robot dog body, the battery box body being located inside the heat-conducting shell, a plurality of heat-conducting sheets being fixedly connected to the bottom surface of the outer wall of the heat-conducting shell, a transmission cavity being provided on the bottom surface of the robot dog body, a transmission mechanism being connected to the inner wall of the transmission cavity, a plurality of air outlets being penetrated through one side of the transmission cavity close to the heat-conducting shell, a cross bracket being fixedly connected to the inner walls of the plurality of air outlets, an output end of the transmission mechanism being penetrated through the plurality of cross brackets and connected to a plurality of fan blades, and the plurality of fan blades being aligned and matched with the plurality of heat-conducting sheets.

[0007] Furthermore, a sealing plate is fixedly connected to one side of the plurality of heat conducting sheets away from the heat conducting shell, and the sealing plate is located below the plurality of fan blades.

[0008] Furthermore, inclined blocks are fixedly connected between the plurality of heat conducting sheets, and the plurality of inclined blocks are located at an end away from the fan blades.

[0009] Furthermore, dustproof nets are fastened and connected between the plurality of heat conducting plates and on the bottom surface of the transmission cavity by bolts.

[0021] like Figures 1 to 6 As shown, when the battery box 5 inside the robot dog body 1 generates heat during operation, the heat will first be guided to the plurality of heat conductive plates 3 by the heat conductive shell 7 wrapped outside the battery box 5, and then the plurality of fan blades 10 will be driven to rotate through the transmission mechanism, thereby forming flowing air between the plurality of heat conductive plates 3, which can further increase the heat dissipation speed, thereby preventing the temperature of the battery box 5 inside the robot dog body 1 from being too high, thereby causing thermal runaway or even battery explosion.

[0022] Special mention should be made here:

[0023] 1. The robot dog body 1 is currently available technology, so it is not introduced in detail.

[0024] 2. There are also circuit boards and mechanisms for driving the limbs to walk inside the trunk of the robot dog body 1. In order to facilitate the display of the positions of components such as the battery box 5 and the heat-conducting shell 7, they are not shown in the figure.

[0025] 3. The transmission mechanism is electrically connected to the internal controller of the robot dog body 1.

[0026] 4. The transmission mechanism can start working when the robot dog body 1 starts running, or it can start working after the robot dog body 1 has been running for a period of time, or a temperature sensor can be installed on the heat conductive sheet 3 and the heat conductive shell 7 of the robot dog body 1, and it can start when the set stability is reached. There is no specific limitation.

[0027] Please refer to Figure 5The transmission mechanism includes a transmission motor 8, a chain 11 and a plurality of gears 12. The outer wall of the transmission motor 8 is fixedly connected to the inner wall of the transmission cavity 101. The sides of the plurality of gears 12 away from the transmission motor 8 are rotatably connected to the plurality of cross brackets 9 respectively, and the same sides of the plurality of gears 12 are fixedly connected to the rotating shafts of the plurality of blades 10 respectively.

The chain 11 is sleeved on the outer walls of the plurality of gears 12 and meshes with the plurality of gears 12.

[0028] More specifically, when it is necessary to dissipate heat from the battery box 5 inside the robot dog body 1, the controller inside the robot dog body 1 will turn on the transmission motor 8. After the transmission motor 8 is started, the output shaft drives the connected gear 12 to rotate. After the gear 12 rotates, it can drive other gears 12 to rotate together through the chain 11, and then drive the several fan blades 10 on the other side of the cross bracket 9 to rotate, so that air can be drawn from the bottom surface of the transmission cavity 101 and blown to the surface of several heat conducting plates 3 through the blowing port 102, thereby accelerating the heat conduction and heat dissipation speed of the heat conducting plates 3.

[0029] Please refer to Figure 1 , Figure 2 and Figure 6 , a plurality of heat-conducting sheets 3 are fixedly connected to a sealing plate 2 on one side away from the heat-conducting shell 7, and the sealing plate 2 is located below a plurality of fan blades 10. By setting the sealing plate 2, firstly, a plurality of heat-conducting sheets 3 can be connected together to form a whole, so that the plurality of heat-conducting sheets 3 are not easily deformed; secondly, a shield can be made below the plurality of heat-conducting sheets 3 to prevent the wind blown by the fan blades 10 from flowing out directly from the bottom of the heat-conducting sheets 3 without blowing the surface of the rear end of the heat-conducting sheets 3 for heat dissipation.

[0030] Please refer to Figure 2 and Figure 6 , a plurality of heat conducting sheets 3 are fixedly connected with an inclined block 6, and a plurality of inclined blocks 6 are located at one end away from the fan blade 10. By providing the inclined block 6, the wind blowing from between the plurality of heat conducting sheets 3 and the sealing plate 2 can be guided so that it can be discharged more smoothly.

[0031] Please refer to Figure 1 and Figure 6 The dustproof net 4 is fastened between the heat conducting sheets 3 and the bottom surface of the transmission cavity 101 by bolts. By setting the dustproof net 4, dust, mosquitoes and the like in the external environment can be prevented from entering the heat conducting space to affect the heat dissipation effect without affecting the air extraction and exhaust of the fan blades 10. And the installation by bolts is also more convenient for disassembly, cleaning and replacement.
