Description

Technical Field

[0001] The present invention belongs to the field of heat conduction technology, and specifically relates to a heat insulation and heat exchange device for a robot power system, and more particularly to a heat insulation and heat exchange device for a fire scene robot power system. Background Art

[0002] With the rapid development of urbanization, the number of high-rise buildings, industrial plants, and other structures has increased rapidly year by year. Firefighting issues in these buildings are becoming a growing threat to building safety, as well as the safety of life and property. Due to the complex environments of factories and high-rise buildings, and the potential storage of flammable and explosive hazardous materials, firefighters face life-threatening situations if they fail to inspect the fire situation and the placement of hazardous materials before entering a fire scene. Therefore, the use of fire-entry robots is a safe and effective measure.

[0003] The power system is a key component in a robot's movements and is prone to heat generation during operation. When a fire robot enters a high-temperature environment, its external temperature is far higher than the ideal operating temperature for the robot's power system. This external temperature is transferred to the power system through heat conduction, and the heat generated by the power system itself is difficult to dissipate. Therefore, it is necessary to ensure that the power system temperature of the robot operating in a fire is within its adaptive range, while also eliminating the heat generated by the motor during operation. In summary, it is necessary to develop an effective thermal insulation and heat exchange device for the robot's power system in a fire environment. Summary of the Invention

[0004] The purpose of the present invention is to address the technical defect that the key components of the robot power system in a fire environment are prone to heat during operation, especially after entering a high-temperature environment, the external temperature heat is transferred to the power system, resulting in difficulty in dissipating the heat of the power system itself, and then making the power system unable to work normally. A heat insulation and heat exchange device for the power system of a fire scene robot is proposed to ensure that the temperature of the power system of the robot working in the fire scene should be within its adaptive range, and at the same time, it is also necessary to eliminate the heat generated by the motor when it is working.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions.

[0006] The heat insulation and heat exchange device of the fire scene robot power system is a sealed structure that can shield heat radiation and heat convection, and includes a heat insulation part and a heat exchange part;

[0007] The heat-insulating part adopts a closed cabin structure formed by an inner cabin, a middle layer of heat-insulating material and an outer frame;

[0008] The outer frame is made of high temperature resistant material and can be directly exposed to fire environment while still maintaining its reliable mechanical properties, providing external connection and support for the overall power system;

[0009] The middle layer insulation material is a low thermal conductivity insulation material that can block heat from entering the inner cabin through heat conduction to the greatest extent possible;

[0010] The motor is located in the lower cabin of the inner cabin;

[0011] The inner cabin provides support for components, mainly motors, while also providing overall protection to prevent insulation materials from entering the inner cabin. A temperature sensor is installed inside the inner cabin to monitor temperature changes inside the cabin in real time. While protecting the components inside the cabin, the robot can also be selected to continue exploration or return based on the cabin temperature.

[0012] The heat exchange part includes an upper cabin, a lower cabin, and a middle part connecting the upper cabin and the lower cabin; the upper cabin is a cold source cabin, the lower cabin is a power cabin, and the middle part includes a heat exchange copper plate and a cooling pipe; the heat exchange copper plate is sandwiched between the upper cabin and the lower cabin, and the cooling pipe is connected to the heat exchange copper plate and evenly arranged around the motor;

[0013] The cabin cover of the upper cabin can be opened and closed quickly for replacing the cooling source;

[0014] The heat generated by the motor in the lower cabin during operation is absorbed by the evenly arranged cooling pipes and transferred to the upper cabin to be absorbed by the cooling source; the cooling pipes are hollow copper tubes filled with heat-conducting fluid and sintered to achieve rapid heat exchange.

[0015] The upper cabin is equipped with a cold source, including but not limited to dry ice;

[0016] Equal height columns are set between the inner cabin and the outer frame to ensure that the insulation material in the middle layer is evenly distributed;

[0017] The equal height columns are made of hollow high temperature resistant material and are connected to the inner cabin and the outer frame by screws through the inner holes;

[0018] The working process of the heat insulation and heat exchange device of the fire scene robot power system is as follows:

[0019] S1: Install the heat-insulating heat exchange device equipped with a power system without a cold source onto the robot;

[0020] S2: Open the cold source cabin cover near the fire scene, install the cold source in the cold source cabin, and close the cold source cabin cover;

[0021] S3: The device enters the fire scene with the robot and starts working;

[0022] S4: After entering the fire scene, the heat insulation part blocks the heat transfer; at the same time, the heat exchange part starts to work, transferring the heat generated by the motor through the cooling pipe to the cold source cabin to be absorbed by the cold source, ensuring that the working environment temperature of the motor is within its adaptive range;

[0023] S5: The temperature of the inner cabin is monitored in real time by a temperature sensor and sent to the communication system for the operator to decide the next action;

[0024] S6: After completing the survey and returning, open the cold source cabin cover and continue to add cold sources to the cold source cabin to achieve rapid cooling of the power cabin.

[0025] Beneficial effects:

[0026] The heat insulation and heat exchange device of the fire scene robot power system of the present invention has the following beneficial effects compared with existing heat insulation and heat exchange devices:

[0027] 1. The heat insulation portion of the device blocks the heat from the external fire environment from entering the inner cabin through heat conduction, heat radiation, and heat convection, protecting the temperature of the components in the inner cabin within an adaptive range and ensuring that the power system of the robot operates within its adaptable temperature range in a fire environment;

[0028] 2. The heat exchange part of the device absorbs the heat generated by the inner cabin itself, preventing the heat generated during its own operation from being unable to dissipate;

[0029] 3. The device allows the robot's power system to return after completing the survey, and the temperature inside the inner cabin will be higher than the initial operating temperature. In order to shorten the time it takes for the robot to repeat its work, cold sources are continuously added to the cold source cabin to achieve rapid cooling of the inner cabin.

[0030] 4. The device uses a temperature sensor to monitor the temperature of the inner cabin in real time and returns the temperature data to the robot operator as a reference for subsequent actions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following describes in detail the specific implementation of a heat insulation and heat exchange device for a power system of a fire scene working robot according to the present invention in conjunction with the accompanying drawings and embodiments.

[0039] Example 1

[0040] Figure 1 This is a schematic diagram of the heat insulation and heat exchange device of the fire scene robot power system of the present invention. In the figure, the device includes a heat insulation part and a heat exchange part. The heat insulation part includes an outer frame 1, a middle layer of heat insulation material 2, and an inner cabin 3.

[0041] Equal height columns 13 are provided between the inner cabin and the outer frame to ensure uniform distribution of the insulation material in the middle layer;

[0042] The heat exchange part includes an upper cabin (cold source cabin 5), a lower cabin (power cabin 6), and a heat exchange copper plate 7 and a cooling pipe 8 connecting the upper cabin and the lower cabin;

[0043] During the specific implementation, the cold source cabin cover 4 is opened and the cold source 9 is placed in; after entering the fire scene, the heat insulation part blocks the heat transfer; at the same time, the heat exchange part starts to work, and the heat generated by the motor 10 is transferred to the cold source cabin 5 through the cooling pipe 8 to be absorbed by the cold source 9; the working environment temperature of the motor 10 is ensured to be within its adaptive range; the bearing 11 is installed on the bearing seat processed on the inner cabin 3 to ensure the smooth power output (output through the power output shaft 12);

[0044] Temperature sensor 14 is glued to the inner cabin 3 below motor 10 using 3M adhesive to monitor the cabin temperature in real time. Motor power and control cables 16, as well as temperature sensor data cable 17, extend through outlet spacers 15 to connect to the power system and avionics system. Figure 2These are the bottom view (a), front view (b) and oblique view (c) of the heat insulation heat exchange device.

[0045] This embodiment provides a heat insulation and heat exchange system for the power system of a working robot in a fire scene. The overall shape is cylindrical, which is convenient for processing the frame structure or the cabin. The motor works in a rotary form, and the cylindrical structure can optimize the use of space. Figure 2 As shown in this embodiment, the heat insulation and heat exchange system for the power system of a robot operating in a fire scene includes an insulation section 18 and a heat exchange section 19. The insulation section 18 is composed of an outer frame 1, a middle layer of insulation material 2, and an inner chamber 3. The outer frame is constructed of a high-temperature resistant material (e.g., titanium alloy) that is directly exposed to the fire scene and maintains excellent mechanical properties at high temperatures. Screws are used to connect the power system to the robot via external supports and connections 18. The outer frame 1 is a completely sealed structure that blocks both convection and radiation from the external fire environment. The middle layer of insulation material 2 has an extremely low thermal conductivity, preventing heat from being transferred from the external fire scene to the inner chamber 3. The inner chamber 3 primarily supports internal components, and its sealed structure prevents the middle layer of insulation material 2 from entering and affecting component operation. Evenly spaced columns 13 of equal height are arranged between the outer frame 1 and the inner chamber 3 to ensure uniform distribution of the insulation material 2 between the outer frame 1 and the inner chamber 3, preventing uneven temperatures within the inner chamber 3. The equirectangular columns 13 are made of high-temperature-resistant material and are hollow cylinders. Screws connect the outer frame 1 and the inner chamber 3 through the hollow cylinders, ensuring structural stability after the entire insulation section 18 is assembled. The heat exchange section 19 is located within the insulation section 18 and is divided into two upper and lower chambers using heat exchange copper sheets 7: the cold source chamber 5 and the power chamber 6. The cold source chamber cover 4 and the cold source chamber 5 are quickly opened and closed using quick-release screws 19, facilitating the filling of the cold source 9 within the cold source chamber 5.

[0046] The cooling pipe 8 passes through the heat exchange copper plate 7 (as Figure 5 As shown), the cooling tube 8 is bent to form an umbrella-shaped cylinder (as shown Figure 6 As shown) around the motor 10, the heat generated by the motor 10 is quickly transferred to the cold source cabin 5 to be absorbed by the cold source 9. The heat exchange copper sheet 7 is an external thread structure, which is connected with the internal thread on the inner cabin 3. There is a motor mounting hole on the heat exchange copper sheet 7 for the installation of the motor 10 (as shown). Figure 5 As shown in Figure 1 ), the power output shaft 12 passes through the bearing 11 and extends out of the power system. A bearing seat is machined on the inner cabin 3 for the bearing 11 to install, ensuring stable power output.

[0047] The temperature sensor 14 is glued to the inner cabin 3 below the motor 10 using 3M adhesive to monitor the cabin temperature in real time. The motor power line and control line 16, as well as the temperature sensor data line 17, extend through the outlet spacer 15 to connect to the power system and the avionics system. The cross-sectional view of the device is shown in FIG. Figure 3 shown.

[0048] The overall working process of this embodiment is as follows:

[0049] like Figure 4 As shown, first install the power system on the robot and transport the robot to the vicinity of the fire scene; open the cold source cabin cover 4, fill a sufficient amount of cold source 9 into the cold source cabin 5, cover the cold source cabin cover 4, and fix the cold source cabin cover with quick release screws 19.

[0050] After the preparations are completed, the power system enters the fire scene with the robot and starts working. The heat insulation part will prevent the heat from the fire from being transferred into the inner cabin 3.

[0051] Motor 10 begins operating, generating heat. This creates a temperature difference between the cooling chamber 5 and the power chamber 6, prompting the heat exchanger to activate. A temperature difference develops between the cooling tube 8's end in the power chamber 6 and the end in the heat exchange copper plate 7. The heat transfer fluid within the cooling tube 8 begins to flow, transferring heat from the high-temperature side to the low-temperature side, bringing the temperatures at both ends of the cooling tube 8 toward equilibrium. Heat is then transferred from the cooling tube 8's end to the heat exchange copper plate 7, which comes into direct contact with the cooling chamber 9, where it is absorbed by the cooling chamber 9 within the cooling chamber 5.

[0052] The temperature sensor 14 in the inner cabin 3 detects the temperature of the inner cabin 3 in real time and transmits it to the avionics component through the temperature sensor data line 17. If the monitored temperature exceeds the warning value, an alarm will be issued to the robot remote control.

[0053] The motor power and control cables 16 and the temperature sensor data cable 17 extend through the power system through outlet spacers and connect to the avionics system. Conventional cables are used inside the cabin for these cables, while the power system's external cables, exposed to the fire, use high-temperature-resistant cables.

[0054] After completing the work, the robot returns, unscrews the quick-release screw 19, and continues to add the cold source 9 to the cold source compartment 5, and the power compartment 6 continues to cool down until the temperature drops to a level that allows the next work to begin.

[0055] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
