Technical Field
[0001] The present application relates to the technical field of firefighting robots, and in particular to a water cooling and heat dissipation system for a high temperature resistant reconnaissance firefighting robot. Background Art
[0002] When the fire situation is unclear and the fire is large, and firefighters cannot enter and carry out firefighting work, the high-temperature resistant reconnaissance robot can directly pass through the fire zone and reach into the high-temperature fire scene to monitor the fire in real time. It has functions such as image acquisition, heat source detection, and environmental detection. It can obtain important information such as the fire location, the situation of trapped people, the nature of the burning material, the way the fire spreads, the scope of the fire, and whether the fire has any impact on key equipment and areas. It provides first-hand data for fire scene rescue command decision-making. When flammable materials leak and spread at the scene, the fire is fierce and people and equipment must retreat to a certain safe distance, the high-temperature resistant reconnaissance fire-fighting robot can continue to hold its position and move freely in the open flame to perform reconnaissance tasks.
[0003] When the high-temperature resistant reconnaissance and firefighting robot is operating in a fire scene, it is necessary to dissipate heat and cool down the external equipment (such as cameras) and internal equipment (motors, batteries, drivers, etc.) of the high-temperature resistant reconnaissance and firefighting robot at the same time, and to ensure the heat insulation effect of the outer shell of the high-temperature resistant reconnaissance and firefighting robot to ensure the stable operation of the internal electronic components of the high-temperature resistant reconnaissance and firefighting robot. Therefore, a heat dissipation system with good heat dissipation and thermal insulation properties is needed to support the operation of the high-temperature resistant reconnaissance and firefighting robot. Summary of the invention
[0004] In order to provide a heat dissipation system with good heat dissipation and heat insulation performance to support the operation of a high-temperature resistant reconnaissance and firefighting robot, the present application provides a water-cooled heat dissipation system for a high-temperature resistant reconnaissance and firefighting robot.
[0005] The present application provides a water cooling system for a high temperature resistant fire detection robot, which adopts the following technical solution:
[0006] A water-cooling heat dissipation system for a high-temperature resistant reconnaissance fire-fighting robot comprises an external water layer structure, a first thermal insulation layer, and an internal water layer structure. The external water layer structure is used to cool the exterior of the fire-fighting robot, and the internal water layer structure is used to cool the internal equipment of the fire-fighting robot. An external water tank is arranged on the external water layer structure, and the external water layer structure is connected to the external water tank. A water pump for extracting water from the internal water layer structure and supplying it to the external water tank is arranged on the internal water layer structure. A second thermal insulation layer is arranged in the external water tank, and external equipment is installed in the second thermal insulation layer.
[0007] By adopting the above technical scheme, the external water layer cools down the outside of the robot, and the internal water layer cools down the inside of the robot. The first thermal insulation layer can isolate most of the external heat to ensure that the internal temperature of the robot will not rise excessively. After the internal water layer cools down the internal equipment, it will continue to flow toward the external water tank under the action of the water pump to spray water to cool the external water tank. The equipment installed in the second thermal insulation layer can maintain a stable operating temperature under the dual action of the external water tank and the second thermal insulation layer, so that the external equipment can work normally, ensuring the thermal insulation performance of the equipment on the high-temperature resistant reconnaissance and firefighting robot. The water inside the external water layer structure will evaporate due to direct contact with higher temperatures. Spraying water on the external water tank also continuously replenishes water in the external water layer structure, so that it can always maintain the external cooling effect, ensuring the heat dissipation performance of the high-temperature resistant reconnaissance and firefighting robot, and supporting the operation of the high-temperature resistant reconnaissance and firefighting robot.
[0008] Preferably, an exhaust port is provided on the external water tank.
[0009] By adopting the above technical solution and setting the exhaust port, since the external water layer structure is connected with the external water tank, the gas generated by evaporation in the external water layer structure and the external water tank will be discharged at the exhaust port, and at the same time, evaporation absorbs heat, which can effectively control the temperature inside the second insulation layer.
[0010] Preferably, the first thermal insulation layer is a rock wool thermal insulation layer.
[0011] By adopting the above technical scheme, the surface of the rock wool insulation layer is strong and firm and can bear a certain weight. While having good insulation effect, it also has good wind resistance and impact resistance, and has the advantages of high temperature resistance, acid and alkali resistance, corrosion resistance, and aging resistance, and can achieve insulation in the harsh environment of a fire scene.
[0012] Preferably, the internal water layer structure is provided with a cold plate heat exchanger for facilitating heat dissipation and cooling of internal equipment.
[0013] By adopting the above technical solution and setting up the cold plate heat exchanger, cooling water can dissipate heat to internal equipment through the internal flow channel of the cold plate heat exchanger, thereby increasing the heat dissipation effect of the internal equipment and ensuring that the internal equipment can maintain a normal operating temperature.
[0014] Preferably, the second thermal insulation layer comprises a rock wool intermediate layer and a thermal insulation cavity layer.
[0015] By adopting the above technical solution, through the setting of the rock wool middle layer and the insulation cavity layer, the rock wool middle layer, the insulation cavity layer and the water in the external water tank form a three-layer protection structure, which can ensure that the operating temperature of the equipment installed inside the insulation cavity layer is controlled below 60°C.
[0016] Preferably, a temperature sensor is provided in the second heat insulation layer.
[0017] By adopting the above technical solution, through the setting of the temperature sensor, the temperature sensor is electrically connected to the external PLC device. The temperature sensor can detect the internal temperature of the second insulation layer in real time and send a signal to the external PLC device. The external PLC device receives and processes the electrical signal. When it is detected that the feedback temperature in the electrical signal is too high, the external PLC device can control and increase the output flow of the water pump, thereby controlling the working environment temperature of the external device.
[0018] Preferably, a cooling water replenishing device is provided on the internal water layer structure.
[0019] By adopting the above technical solution and providing a cooling water replenishing device, when the water in the internal water layer structure is about to run out, it can be replenished through the cooling water replenishing device to ensure long-term operation.
[0020] Preferably, the internal water layer structure can hold at least 120 liters of water.
[0021] By adopting the above technical solution, the internal water layer can accommodate the minimum water requirement, so that the robot itself has a certain weight while ensuring normal operation for a certain period of time.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. Through the arrangement of the internal water layer structure, the first heat insulation layer, the external water layer structure, the external water tank, and the second heat insulation layer, the external water layer structure cools down the outside of the robot, and the internal water layer structure cools down the internal equipment of the robot. The first heat insulation layer and the second heat insulation layer can isolate most of the external heat, ensuring that the temperature of the equipment on the robot will not rise excessively. After the internal water layer structure cools down the inside, it will be passed into the external water tank to continuously replenish water and cool down the outside, ensuring the heat dissipation effect of the external equipment and enabling the external equipment to work normally, ensuring the heat dissipation performance of the robot, and realizing the normal operation of the high-temperature resistant reconnaissance and firefighting robot;
[0024] 2. Through the setting of the temperature sensor, when the temperature sensor detects that the working temperature is too high, the PLC device can be used to control the water pump to increase the output flow rate for cooling, so as to keep the temperature within the normal temperature range;
[0025] 3. By setting up a cooling water replenishing device, cooling water can be replenished, which is convenient for ensuring long-term operation of the robot. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1 This application is described in further detail.
[0029] The embodiment of the present application discloses a water cooling and heat dissipation system for a high temperature resistant reconnaissance and fire fighting robot.
[0030] like Figure 1 As shown, a water cooling and heat dissipation system of a high-temperature resistant reconnaissance and fire-fighting robot includes an external water layer structure 1, a first insulation layer 2, and an internal water layer structure 3. In this embodiment, the thickness of the internal water layer structure 3 is at least 50 mm. The internal water layer structure 3 will form a protective layer of water installed by the shell inside the robot. The internal water layer structure 3 can accommodate at least 120 liters of water. The internal water layer structure 3 is also connected to a cooling water replenishing device 10. The cooling water replenishing device 10 is a fireproof hose connected to the internal water layer structure 3. The fireproof hose can be connected to an external water source and replenish water to the internal water layer structure 3. The internal water layer structure 3 is located inside the first insulation layer 2. A water pump 5 is installed on the internal water layer structure 3. A cold plate heat exchanger 8 is also installed on the internal water layer structure 3 for facilitating heat dissipation and cooling of internal equipment. The cooling water in the internal water layer structure 3 flows into the internal flow channel of the cold plate heat exchanger 8 to dissipate heat for batteries and other equipment installed inside the robot in real time.
[0031] like Figure 1As shown, the first insulation layer 2 is a rock wool insulation layer, which separates the inside of the robot from the outside of the robot and is used as a substitute for the shell of the robot. The external water layer structure 1 is arranged on the outside of the robot to cool the outside of the robot. In this embodiment, the thickness of the external water layer structure 1 on the outside of the robot is at least 20 mm. The external water layer structure 1 will form a protective layer on the outside of the robot that is filled with water by the shell. An external water tank 4 is installed on the external water layer structure 1, and the external water tank 4 is connected to the water channel in the external water layer structure 1. A second insulation layer 6 is installed inside the external water tank 4. The second insulation layer 6 includes a rock wool intermediate layer 61 and an insulation cavity layer 62. The external device is installed inside the second insulation layer 6. Furthermore, the external device is installed in the insulation cavity layer 62 and is powered by a battery arranged inside. In this embodiment, the heat-insulating cavity layer 62 is made of laminated glass, which can effectively insulate without blocking the equipment. On the outside of the external equipment, a three-layer heat dissipation or heat-insulating protection structure of water, heat-insulating cavity and rock wool is formed, which can ensure that the working temperature of the external equipment is controlled below 60°C. An exhaust port 7 is opened on the upper side of the water tank, and the upper side of the water tank is opposite to the pipeline of the internal water layer structure 3 passing through the first insulation layer 2. After cooling the internal equipment, the internal water layer structure 3 will be discharged outwardly and sprayed to the water tank under the action of the water pump 5. On the one hand, water is replenished to the external water layer structure 1 connected to the water tank, and on the other hand, the water tank is cooled to maintain the working temperature of the external equipment. At the same time, the water vapor evaporated by heat in the water tank and the external water layer structure 1 will also be discharged along the exhaust port 7, which is convenient for controlling the temperature of the water tank.
[0032] like Figure 1 As shown, a temperature sensor 9 is also installed in the insulation cavity layer 62. The temperature sensor 9 is electrically connected to the external PLC device. The temperature sensor 9 can detect the internal temperature of the second insulation layer 6 in real time and send a signal to the external PLC device. The external PLC device receives and processes the electrical signal. When it is detected that the feedback temperature in the electrical signal is too high, the external PLC device can control and increase the output flow of the water pump 5, thereby controlling the working environment temperature of the external device.
[0033] The implementation principle of the first embodiment of the present application is: when put into actual use, the internal water layer structure 3 cools the inside of the robot, and the external water layer structure 1 cools the outside of the robot. At the same time, the first insulation layer 2 isolates most of the external heat, reducing the impact of the external heat on the inside of the robot. Since the external water layer structure 1 is greatly affected by the fire, the external water layer structure 1 will evaporate continuously. After cooling the inside, the water in the internal water layer structure 3 is sprayed to the external water tank 4 under the action of the water pump 5 to replenish and cool the external water layer structure 1. The equipment outside the robot is installed in the second insulation layer 6 and is located in the external water tank 4. A three-layer heat dissipation and insulation structure is used to cool the external equipment to ensure the working temperature.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
