[0001] The invention relates to the technical field of fire-fighting robots, and in particular to a water cooling and heat dissipation system of an explosion-proof fire-fighting robot. Background Art
[0002] Traditional fire rescue is usually carried out by firefighters, but the fire scene environment is complex and in a high-risk fire rescue environment, it is very easy to cause casualties among firefighters.
[0003] Existing high-risk fire rescue operations usually use explosion-proof fire-fighting robots. Explosion-proof fire-fighting robots are a type of special robot and are used in high-risk fire rescue operations, fire rescue in large oil and chemical companies, tunnels, subways and other places that are prone to collapse and need to enter for rescue and firefighting, rescue environments with flammable gas and liquid leakage, and a high possibility of explosion, rescue environments with thick smoke, toxic and harmful gases, and rescue environments where close-range firefighting is required and casualties are likely to occur when people get close. Therefore, all electrical parts of the fire-fighting robot are explosion-proof, and the internal cavity of the robot is isolated from the outside air to prevent the electric sparks generated inside from igniting the external flammable gas, thereby avoiding casualties among firefighters through rescue operations with explosion-proof fire-fighting robots.
[0004] However, the internal cavity of the robot is isolated from the outside air, which causes the motor and driver, two huge heat sources, to remain inside the cavity. The temperature inside the cavity rises sharply, which can easily cause damage to the internal electrical components of the robot. Summary of the invention
[0005] The purpose of the present invention is to provide a water-cooling heat dissipation system for an explosion-proof fire-fighting robot, which aims to solve the problem that the internal cavity of the robot is isolated from the external air, which leads to the motor and the driver inside the internal cavity, two heat sources with huge heat generation, being always inside the cavity, causing the temperature inside the cavity to rise sharply, thus easily causing damage to the internal electrical components of the robot.
[0006] To achieve the above-mentioned objectives, the present invention provides a water-cooling and heat dissipation system for an explosion-proof fire-fighting robot, comprising a water pump, a first water-cooled motor, a water tank, a water-cooled driver, a second water-cooled motor and an explosion-proof radiator, wherein the first water-cooled motor is connected to the water pump and is located on one side of the water pump, the water tank is connected to the first water-cooled motor and is located on a side of the first water-cooled motor away from the water pump, the water-cooled driver is connected to the water tank and is located on a side of the water tank away from the first water-cooled motor, the second water-cooled motor is connected to the water-cooled driver and is located on a side of the water-cooled driver away from the water tank, and the explosion-proof radiator is connected to the second water-cooled motor and the water pump respectively, and the explosion-proof radiator is located on a side of the second water-cooled motor close to the water pump.

[0008] The water cooling system of the explosion-proof fire-fighting robot further includes a second cable gland, and the second cable gland is arranged between the explosion-proof radiator and the water pump.
[0009] The water-cooling heat dissipation system of the explosion-proof fire-fighting robot further comprises a first clamp, which is arranged on the water-cooling driver and located on one side of the water-cooling driver.
[0010] Among them, the water cooling and heat dissipation system of the explosion-proof fire-fighting robot also includes a second clamp, which is arranged on the first water-cooled motor and is located on one side of the first water-cooled motor.
[0011] Among them, the water cooling and heat dissipation system of the explosion-proof fire-fighting robot also includes a third clamp, and the third clamp is arranged on the second water-cooled motor and is located on one side of the second water-cooled motor.
[0012] Among them, the water cooling and heat dissipation system of the explosion-proof fire-fighting robot also includes a fourth clamp, and the fourth clamp is arranged on the water pump and is located on one side of the water pump.
[0013] The present invention provides a water-cooling heat dissipation system for an explosion-proof fire-fighting robot. When the explosion-proof fire-fighting robot starts to run, the water pump also starts to run. Driven by the water pump, the coolant passes through the first water-cooling motor, the water tank, the water-cooling driver, the second water-cooling motor in sequence, and finally reaches the explosion-proof radiator. The fan in the explosion-proof radiator blows heat into the air to reduce the temperature of the coolant. The coolant with reduced temperature flows back to the water pump, thereby achieving the purpose of dissipating heat in the cavity of the fire-fighting robot by water-cooling heat dissipation, avoiding the heat in the cavity of the fire-fighting robot from not being able to be dissipated, and further avoiding damage to electrical components inside the cavity.

DETAILED DESCRIPTION
[0018] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.
[0019] The first embodiment of the present application is:
[0020] See also Figure 1 and Figure 2 ,in Figure 1 Schematic diagram of the structure of the explosion-proof fire-fighting robot according to the first embodiment of the present invention. Figure 2 It is a schematic structural diagram of the water cooling and heat dissipation system of the explosion-proof fire-fighting robot according to the first embodiment of the present invention.
[0021] The present invention provides a water cooling and heat dissipation system for an explosion-proof fire-fighting robot, comprising a water pump 101, a first water-cooled motor 102, a water tank 103, a water-cooled driver 104, a second water-cooled motor 105, an explosion-proof radiator 106, a first cable gland 107, a second cable gland 108, a first clamp 109, a second clamp 110, a third clamp 111 and a fourth clamp 112. The above solution solves the problem that the internal cavity of the robot is isolated from the external air, which results in the motor and the driver, two heat sources with huge heat generation, being inside the cavity all the time, causing the temperature inside the cavity to rise sharply, which can easily cause damage to the internal electrical parts of the robot. It can be understood that the above solution can be used when it is necessary to dissipate heat inside the fire-fighting robot.
[0022] In this embodiment, the water-cooled driver 104 and the first water-cooled motor 102 and the second water-cooled motor 105 are installed in the inner cavity of the fire-fighting robot, and heat is dissipated by water-cooling circulation to avoid heat accumulation in the robot cavity and damage to electrical components in the robot cavity.
[0023] The first water-cooled motor 102 is connected to the water pump 101 and is located on one side of the water pump 101. The water tank 103 is connected to the first water-cooled motor 102 and is located on a side of the first water-cooled motor 102 away from the water pump 101. The water-cooled driver 104 is connected to the water tank 103 and is located on a side of the water tank 103 away from the first water-cooled motor 102. The second water-cooled motor 105 is connected to the water-cooled driver 104 and is located on a side of the water-cooled driver 104 away from the water tank 103. The explosion-proof radiator 106 is connected to the second water-cooled motor 105 and the water pump 101 respectively. The explosion-proof radiator 106 is located on the side of the second water-cooled motor 105 close to the water pump 101. The water pump 101 and the first water-cooled motor 102 are connected by an explosion-proof water-cooling pipe. The water tank 103 and the first water-cooled motor 102 are connected by an explosion-proof water-cooling pipe. The water-cooled driver 104 is connected to the water tank 103 by an explosion-proof water-cooling pipe. The second water-cooled motor 105 and the water-cooled driver 104 are connected by an explosion-proof water-cooling pipe. The explosion-proof radiator 106 is connected with the second water-cooled motor 105 and the water pump 101 respectively by an explosion-proof water-cooling pipe, and the walking of the explosion-proof fire-fighting robot can be controlled by the first water-cooled motor 102 and the second water-cooled motor 105. The water-cooling driver 104 can drive the first water-cooled motor 102 and the second water-cooled motor 105 at the same time. The water tank 103 stores coolant, so that when the explosion-proof fire-fighting robot starts running, the water pump 101 also starts running, and the coolant in the water pump 101 Driven by the first water-cooled motor 102, the water tank 103, the water-cooled driver 104, the second water-cooled motor 105, and finally reach the explosion-proof radiator 106. The fan in the explosion-proof radiator 106 blows the heat into the air, so that the temperature of the coolant is reduced. The coolant with reduced temperature flows back to the water pump 101, so as to achieve the purpose of heat dissipation in the cavity of the fire-fighting robot by water cooling, so as to avoid the heat in the cavity of the fire-fighting robot from not being able to be dissipated, and further avoid damage to the electrical components inside the cavity.
[0024] Secondly, the first gland 107 is arranged between the second water-cooled motor 105 and the explosion-proof radiator 106, and the second gland 108 is arranged between the explosion-proof radiator 106 and the water pump 101. The first gland 107 and the second gland 108 are both composed of a clamping nut, a sealing ring, a gasket, a main body and a thread. The explosion-proof water-cooling pipe between the second water-cooled motor 105 and the explosion-proof radiator 106 passes through the first gland 107, and the explosion-proof water-cooling pipe between the second explosion-proof radiator 106 and the water pump 101 passes through the second gland 108. At this time, the clamping nuts of the first gland 107 and the second gland 108 are tightened, and the sealing ring will be squeezed and reduced by the gasket, resulting in a tight combination of the explosion-proof water-cooling pipe and the sealing ring, so that the inside and outside of the explosion-proof cavity are isolated, thereby achieving the effects of explosion-proof, sealing and waterproof.
[0025] Finally, the first clamp 109 is arranged on the water-cooled driver 104 and is located on one side of the water-cooled driver 104, the second clamp 110 is arranged on the first water-cooled motor 102 and is located on one side of the first water-cooled motor 102, the third clamp 111 is arranged on the second water-cooled motor 105 and is located on one side of the second water-cooled motor 105, the fourth clamp 112 is arranged on the water pump 101 and is located on one side of the water pump 101, the explosion-proof water-cooling pipe on the water-cooled driver 104 is fixed by the first clamp 109, the explosion-proof water-cooling pipe on the first water-cooled motor 102 is fixed by the second clamp 110, the explosion-proof water-cooling pipe on the second water-cooled motor 105 is fixed by the third clamp 111, the explosion-proof water-cooling pipe on the water pump 101 is fixed by the fourth clamp 112, and the first clamp 1 09. The inner liners of the second clamp 110, the third clamp 111 and the fourth clamp 112 are all flanged, so as to prevent the inner liners of each clamp from causing wear to the explosion-proof water-cooling pipes on each device. At the same time, each clamp has five groups of stainless steel spring washers, so that the five groups of spring washers use the rebound force generated by their own elastic deformation to continuously apply an axial force to the nuts or bolts of each clamp, so that a certain pressure is maintained between the threads, thereby increasing the friction force and effectively preventing the nuts or bolts of each clamp from loosening due to vibration. Therefore, by locking the first clamp 109, the second clamp 110, the third clamp 111 and the fourth clamp 112 on the water-cooled driver 104, the first water-cooled motor 102, the second water-cooled motor 105 and the water pump 101, it is possible to prevent the explosion-proof water-cooling pipes on each device from falling off, thereby preventing the coolant from leaking into the explosion-proof cavity.
[0026] When using the water cooling and heat dissipation system of an explosion-proof fire-fighting robot implemented in this embodiment, when the explosion-proof fire-fighting robot starts running, the water pump 101 also starts running. Driven by the water pump 101, the coolant passes through the first water-cooled motor 102, the water tank 103, the water-cooled driver 104, the second water-cooled motor 105 in sequence, and finally reaches the explosion-proof radiator 106. The fan in the explosion-proof radiator 106 blows the heat into the air to reduce the temperature of the coolant. The coolant with reduced temperature flows back to the water pump 101, thereby achieving the purpose of heat dissipation in the cavity of the fire-fighting robot by water cooling, avoiding the heat in the cavity of the fire-fighting robot from not being able to dissipate, and further avoiding damage to the electrical components inside the cavity.
