The motor module is the main source that generates heat of patrolling and examining the robot, therefore in order to guarantee to patrol and examine the radiating effect of robot, need to guarantee that the heat of motor module can in time outwards discharge.

The following detailed description of implementations of the present application is provided in conjunction with specific embodiments.

As shown in fig. 1 to fig. 3, an inspection robot according to an embodiment of the present application includes a sealed vehicle body 1 having a receiving cavity 11, a motor module 2 disposed in the receiving cavity 11, and a heat dissipation assembly 3 in heat conduction contact with the motor module 2; referring to fig. 8, the heat dissipation assembly 3 includes an air inlet fan 31 hermetically connected to the sealed vehicle body 1, an air outlet fan 32 hermetically connected to the sealed vehicle body 1, and a heat dissipation metal plate 33 connected between the air inlet fan 31 and the air outlet fan 32; the heat dissipation metal plate 33 is positioned in the accommodating cavity 11 and is in heat conduction contact with the motor module 2; the heat dissipation metal plate 33 has a heat dissipation cavity 334, and referring to fig. 7, the heat dissipation metal plate 33 is provided with an air inlet 3311 and an air outlet 3321 communicated with the heat dissipation cavity 334; the air inlet fan 31 is hermetically connected to the heat dissipation metal plate 33 at the air inlet 3311, and the air outlet fan 32 is hermetically connected to the heat dissipation metal plate 33 at the air outlet 3321.

In the embodiment of the present application, the heat dissipation assembly 3 composed of the air inlet fan 31, the air outlet fan 32, and the heat dissipation metal plate 33 is isolated from the components to be cooled by heat dissipation. The heat dissipation and cooling process comprises the following steps: the air intake fan 31 introduces external normal temperature air into the heat dissipation cavity 334 of the heat dissipation metal plate 33 through the air intake 3311, and moves a distance in the heat dissipation cavity 334 and then leaves the heat dissipation metal plate 33 from the air outlet 3321; because the heat dissipation metal plate 33 is in heat conduction contact with the motor module 2, when the air moves in the heat dissipation cavity 334 of the heat dissipation metal plate 33, the heat transferred to the heat dissipation metal plate 33 by the motor module 2 can be taken away, and further the heat dissipation of the motor module 2 is realized; because the heat dissipation metal plate 33 is located in the accommodating cavity 11 of the sealed vehicle body 1, heat generated by other heat generating components in the accommodating cavity 11 can be transferred to the heat dissipation metal plate 33 through the air inside the accommodating cavity 11, thereby realizing heat dissipation of other components in the accommodating cavity 11.

Because the motor module 2 is the largest heating source and the heat dissipation metal plate 33 is directly in heat conduction contact with the motor module, the heat of the largest heating source can be directly and rapidly discharged outwards; for the mode that the biggest source of generating heat passes through the air in the holding chamber 11 to the transmission of heat dissipation metal sheet 33, effectively promoted heat dissipation cooling's effect. Meanwhile, air entering the heat dissipation cavity 334 cannot leave the heat dissipation metal plate 33, so that dust and water mist possibly existing in the air in extreme weather cannot leave the heat dissipation metal plate 33 to reach other positions of the accommodating cavity 11, and the waterproof and dustproof effects of the inspection robot are met.

It can be understood that the dust and the water mist in the air entering the heat dissipation cavity 334 of the heat dissipation metal plate 33 can be discharged by the air outlet fan 32, and the dust accumulation caused by long-term use can be treated by replacing the heat dissipation metal plate 33 or cleaning the heat dissipation metal plate 33.

It is understood that the surface of the sealed vehicle body 1 has a combination of a dust screen and waterproof asbestos or equivalent to ensure the waterproof and dustproof effects of the other parts of the sealed vehicle body 1.

The first air guiding groove 341 on the first air guiding plate 34 enables the air in the heat dissipation cavity 334 to move along a predetermined direction and region, that is, the air is concentrated at the first air guiding groove 341 and moves along the length direction of the first air guiding groove 341, and since the first air guiding groove 341 corresponds to the motor module 2, the air in the heat dissipation cavity 334 is concentrated at the motor module 2 and disperses the heat generated by the motor module 2 to the heat metal plate 33. The heat is dissipated in a mode that the heat dissipation air is concentrated in the main heating source, and the heat dissipation effect is improved.

Further, referring to fig. 6, as another specific embodiment of the inspection robot provided in the present application, the first air guiding plate 34 is further provided with a second air guiding groove 342 and a third air guiding groove 343; the second wind-guiding groove 342 and the third wind-guiding groove 343 are respectively located at two opposite sides of the first wind-guiding groove 341; the widths of the second wind-guiding groove 342 and the third wind-guiding groove 343 are both greater than the width of the first wind-guiding groove 341. The width of the first air guiding groove 341 is the smallest, so that the speed of air flowing through the first air guiding groove 341 is the fastest, the speed of air flow exchange at the area is accelerated, and the heat dissipation efficiency of the motor module 2 is ensured. The main heating source in the inspection robot is the motor module 2, other parts which generate heat seriously can be used, the other parts which generate heat seriously can be corresponding to the second air guide groove 342 or the third air guide groove 343, and the air flow velocity at the positions of the second air guide groove 342 and the third air guide groove 343 is slightly smaller than that at the position of the first air guide groove 341, so that the air flow exchange speed is slightly smaller, but the heat dissipation and cooling effects can be ensured for the parts which generate heat less than the motor module 2. The arrangement of the first air guide groove 341, the second air guide groove 342 and the third air guide groove 343 reasonably distributes the heat dissipation airflow according to the requirement, so that the heat generated by the cooled parts at all places can be timely discharged, and the temperature at all places can be well controlled. The need for total airflow is reduced relative to providing the same heat dissipating airflow throughout. Since the width of the first air guiding groove 341 is the smallest, the number of the first air guiding grooves 341 per unit area is the largest, that is, the number of the inner walls of the first air guiding groove 341 is plural, thereby increasing the heat dissipation area.

Further, referring to fig. 6, as another specific embodiment of the inspection robot provided in the present application, a notch 3431 is formed on an inner wall of the third air guiding groove 343. When the number of the motor modules 2 of the inspection robot is multiple, for example, two, the number of the first air deflectors 34 is two, one first air deflector 34 corresponds to one motor module 2, and the two first air deflectors 34 are both located in the heat dissipation metal plate 33, so that when the first air deflector 34 dissipates heat of the first motor module 2, in order to ensure that the second motor module 2 can also dissipate heat by lower-temperature air, the notch 3431 at the third air guide groove 343 at the first air deflector 34 allows the lower-temperature air to leave the first air deflector 34 and reach the next first air deflector 34, enter the next first air guide groove 341, the second air guide groove 342 and the third air guide groove 343, and dissipate heat of the next motor module 2.

Further, referring to fig. 5, as another specific embodiment of the inspection robot provided in the present application, a second air guiding plate 35 and a third air guiding plate 36 are further disposed in the heat dissipation cavity 334; the second air guiding plate 35 is provided with a fourth air guiding groove 351, and the third air guiding plate 36 is provided with a fifth air guiding groove 361; the second air guiding plate 35 is located between the air intake fan 31 and the first air guiding plate 34 to introduce the air at the air inlet 3311 into the first air guiding plate 34, so as to realize the concentration of the air at the first air guiding plate 34; the third air guiding plate 36 is located between the air outlet fan 32 and the first air guiding plate 34 to guide the air in the heat dissipation cavity 334 to the air outlet 3321 and leave the heat dissipation metal plate 33, so that the hot air can quickly leave the heat dissipation metal plate 33, and the heat dissipation efficiency is prevented from being affected by the hot air flowing in the heat dissipation metal plate 33.

Further, referring to fig. 4, as another specific embodiment of the inspection robot provided in the present application, the heat dissipation metal plate 33 includes a first heat dissipation part 331 connected to the air intake fan 31, a second heat dissipation part 332 connected to the air outlet fan 32, and a heat dissipation connection part 333 connected between the first heat dissipation part 331 and the second heat dissipation part 332. Air enters the first heat dissipation part 331 through the air inlet 3311, flows through a certain heat dissipation stroke, enters the second heat dissipation part 332 through the heat dissipation connecting part 333, and then flows through a certain heat dissipation stroke in the second heat dissipation part 332 for heat dissipation; the coverage of a large area is realized in the minimum area, and the heat dissipation efficiency is improved.

When the number of the motor modules 2 is two, the two motor modules 2 correspond to the two first air deflectors 34 respectively, so that the air in the heat dissipation metal plate 33 is concentrated at the two first air deflectors 34 to dissipate heat of the motor modules 2.
