Description

Technical Field

[0001] This invention relates to the field of firefighting robot technology, and more specifically, to a cooling system for a firefighting robot used in multi-condition operations and its operating method. Background Technology

[0002] With the advancement of urban construction, the number of high-rise and super high-rise buildings has increased dramatically, bringing new challenges to fire protection. Improper handling can cause enormous losses of life and property. To effectively improve rescue efficiency and overcome fire rescue difficulties, various firefighting robots have been developed to assist firefighters in carrying out firefighting tasks in high-rise buildings.

[0003] However, existing firefighting robots directly face fire scenes when performing tasks, and their components generate heat during operation. Therefore, the optimized design of the cooling system is particularly critical. Existing firefighting robots suffer from low protection levels and a lack of effective cooling for internal components, resulting in low working efficiency under high-temperature conditions and a significantly shortened lifespan.

[0004] Some firefighting robots are equipped with automatic sprinkler cooling devices, but their sprinkler cooling water delivery pipelines lack effective protection. When the firefighting robot enters a high-temperature fire scene, the water curtain will not be able to completely protect the robot as a whole, causing the circuits to age rapidly and reducing the robot's service life. Furthermore, the automatic sprinkler cooling technology only cools the outer shell of the firefighting robot. The radiant heat inside the firefighting robot and the heat generated by its various components during operation cannot be effectively exchanged, which will shorten the working time of the firefighting robot in the fire scene. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling system for a fire-fighting robot and its operation method for multi-condition operation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for operating a cooling system for a fire-fighting robot under multiple operating conditions, comprising the following steps:

[0007] Step 1: When the fire-fighting robot enters the fire scene, the large and small water tanks are filled with cold storage material.

[0010] Step 2: When the fire-fighting robot participates in fire-fighting operations, all external pipeline valves are opened. External water enters the distributor through the deceleration valve and is output to each external pipeline valve through the distributor. All solenoid valves are in the state of being connected to the external pipeline. External water flows through each branch, thereby cooling the various components of the fire-fighting robot.

[0011] Step 3: When the fire-fighting robot is operating in a non-fire environment, all external pipeline valves are closed, all solenoid valves are disconnected from the external pipelines and kept closed, and the various components of the fire-fighting robot can be cooled by air using the two fans installed on it.

[0020] The second cooling mechanism includes a reducer and a second coil. The second coil is disposed inside the small water tank. The outlet pipe of the second coil is coiled around the outside of the reducer, and the inlet pipe passes through the small water tank.

[0023] The outlet of the third water pump is connected to the inlet of the solenoid valve VI via a pipe, and the outlet of the second water pump is connected to the inlet of the solenoid valve IV via a pipe.

The present invention has three cooling methods for cooling the firefighting robot, which are respectively used to deal with three working conditions: entering the fire scene, participating in firefighting operations, and performing operations in non-fire scene environments, effectively enhancing the multi-functionality of the firefighting robot.

[0027] Second, this invention greatly improves the heat dissipation efficiency of the fire-fighting robot by setting up an internal cooling cycle, thereby increasing its working time in the fire scene. The internal cooling cycle of the fire-fighting robot is divided into three parts, which dissipate heat from each internal component, ensuring the normal operation of the internal components of the fire-fighting robot during operation.

[0028] Third, this invention enables the fire-fighting robot to adaptively switch its cooling system when dealing with different fire-fighting scenarios by installing solenoid valves on various branch pipelines inside the fire-fighting robot and connecting them to the electrical control cabinet and circuit system.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 The present invention provides a cooling system for a fire-fighting robot for multi-condition operation, including a first cooling mechanism, a second cooling mechanism, a third cooling mechanism and a fourth cooling mechanism.

[0033] In this embodiment, the first cooling mechanism includes a small water tank 13, a battery pack 2, and a first coil 101. The first coil 101 is located inside the small water tank 13. The water outlet pipe of the first coil 101 is coiled around the outside of the battery pack 2, and the water return pipe passes through the small water tank 13. A solenoid valve I 16, a solenoid valve II 17, and a first water pump 601 are installed on the first coil 101.

[0034] In the first cooling mechanism, the ethylene glycol aqueous solution reaches the battery pack 2 through the internal cooling circulation pipe of the battery pack 2, absorbs the heat of the battery pack 2 and flows out, flows through point b of solenoid valve I 16 to the first water pump 601, and reaches the small water tank 13 through the action of the first water pump 601. It flows through the first coil 101 in the small water tank 13 for heat exchange. The cooled ethylene glycol aqueous solution flows through point p of solenoid valve II 17 to the battery pack 2, absorbs the heat generated by the battery pack 2 again, thus forming a cycle and ensuring the normal operation of the battery pack 2.

[0035] In this embodiment, the second cooling mechanism includes a reducer 12 and a second coil 102. The second coil 102 is disposed inside the small water tank 13. The water outlet pipe of the second coil 102 is coiled around the outside of the reducer 12, and the water inlet pipe passes through the small water tank 13.

[0036] In the second cooling mechanism, gear oil flows through the reducer 12, carrying away the heat generated by the reducer 12. It then flows through the second coil 102 in the small water tank 13 to exchange heat with the ice water. The cooled gear oil continues to flow through the reducer 12, thus forming a circulation and ensuring the normal operation of the reducer 12.

[0037] In this embodiment, the third cooling mechanism includes a chiller 1, a water-cooled cover 4, an electrical control cabinet 5, and a large water tank 14. The chiller 1 is connected to a distributor 3. One of the outlet pipes of the distributor 3 is connected to the inlet pipe of the water-cooled cover 4. The inlet pipe of the water-cooled cover 4 is equipped with a solenoid valve IV 19, and the outlet pipe of the water-cooled cover 4 is equipped with a solenoid valve III 18. The water-cooled cover 4 is mounted on the electrical control cabinet 5. The outlet pipe of the water-cooled cover 4 is connected to the large water tank 14. A second water pump (602) and a third water pump (603) are symmetrically mounted on the large water tank 14.

[0038] In the third cooling mechanism, the water flows from the large water tank 14 through the second water pump 602 and point p of the three-way solenoid valve IV 19 to the water cooling cover 4, carrying away the heat generated by the sensor inside the water cooling cover 4 and flowing out. It continues to flow into the electrical control cabinet 5, carrying away the heat generated by the electrical control cabinet 5 and flowing out. It flows through point b of the three-way solenoid valve III 18 and finally flows back to the large water tank 14, thus forming a cycle.

[0039] In addition, in the third cooling mechanism, the cooling of the electrical control cabinet 5 and the water cooling cover 4 can also be achieved by the external pipeline valve II 24 flowing through the p point of the solenoid valve IV 19 to the water cooling cover 4, absorbing the heat generated by the sensor inside the water cooling cover 4 and flowing out, then flowing to the electrical control cabinet 5, absorbing the heat generated by the operation of the electrical control cabinet 5 and flowing out, passing through the a point of the solenoid valve III 18 and flowing out of the fire robot, thereby further maintaining the normal operation of the electrical control cabinet 5 and the sensor.

[0040] In this embodiment, the fourth cooling mechanism includes a motor 7 and a hydraulic device 8. A solenoid valve VI 21 is installed on another outlet pipe of the distributor 3. Small heat exchangers 9 are connected to both the motor 7 and the hydraulic device 8. The outlet of the solenoid valve VI 21 is connected to the inlet of one of the small heat exchangers 9 through a pipe body. The outlet of the other small heat exchanger 9 is connected to a solenoid valve V 20 through a pipe body. The outlet of the solenoid valve V 20 is connected to the large water tank 14 through a pipe body. The outlet of the second water pump 602 is connected to the inlet of the solenoid valve IV 19 through a pipe body.

[0041] In the fourth cooling mechanism, the circulating cooling medium is ice water in the large water tank 14. The ice water flows from the large water tank 14 through the third water pump 603 and point b of the solenoid valve VI 21 to the small heat exchanger 9 inside the motor 7. In the small heat exchanger 9, it exchanges heat with the cooling medium of the motor 7. After flowing out, it enters the small heat exchanger 9 inside the hydraulic device 8 and exchanges heat with the cooling medium in the hydraulic device 8. After flowing out, it flows back to the large water tank 14 through point p of the solenoid valve V 20, thus forming a circulation and ensuring the normal operation of the motor 7 and the hydraulic device 8.

[0042] Specifically, one of the outlet pipes of the distributor 3 is equipped with an external pipeline valve I23, the inlet pipe of the distributor 3 is equipped with a deceleration valve 15, the other two outlet pipes of the distributor 3 are equipped with external pipeline valves II24 and III25 respectively, a chiller 1 is installed on the outlet pipe of the distributor 3, one outlet of the chiller 1 is connected to the decelerator 12 through a pipe body, the other outlet of the chiller 1 is connected to the inlet of the solenoid valve II17 through a pipe body, the other inlet of the chiller 1 is connected to the outlet of the solenoid valve I16 through a pipe body, and a fan 11 is installed on the outside of the small heat exchanger 9.

[0043] When the fire-fighting robot participates in fire-fighting operations, under this condition, the internal equipment of the fire-fighting equipment relies on the water source of the internal external pipeline for heat dissipation. At this time, external pipeline valve I23, external pipeline valve II24, and external pipeline valve III25 are all in the open state, and the external water is divided into three branches through the deceleration valve 15 and the diverter 3.

[0044] It should be noted that solenoid valves I16, II17, III18, IV19, V20, and VI21 ​​are all three-way solenoid valves and are all connected to the circuit in electrical control cabinet 5.

[0045] Based on the above technical solutions, the working steps of this solution are summarized as follows:

[0046] When the firefighting robot enters the fire scene: In the first cooling mechanism, ethylene glycol aqueous solution reaches battery pack 2 through the internal cooling circulation pipe, absorbs the heat of battery pack 2, and flows out, passing through point b of solenoid valve I 16 to the first water pump 601. Through the action of the first water pump 601, it reaches the small water tank 13, flows through the first coil 101 in the small water tank 13 for heat exchange, and the cooled ethylene glycol aqueous solution flows through point p of solenoid valve II 17 to battery pack 2, again absorbing the heat generated by battery pack 2, thus forming a cycle to ensure the normal operation of battery pack 2; In the second cooling mechanism, gear oil flows through reducer 12, carrying away the heat generated by reducer 12, flows through the second coil 102 in the small water tank 13, exchanges heat with ice water, and the cooled gear oil continues to flow through reducer 12, thus forming a cycle to ensure the normal operation of reducer 12; The third... In the first cooling mechanism, the water flows from the large water tank 14 through the second water pump 602 and point p of the three-way solenoid valve IV 19 to the water-cooled cover 4, carrying away the heat generated by the sensor inside the water-cooled cover 4 and flowing out. The water-cooled cover 4 can continuously cool the electrical control cabinet 5. The water flows through point b of the three-way solenoid valve III 18 and finally flows back to the large water tank 14, thus forming a cycle. In the fourth cooling mechanism, the circulating cooling medium is ice water in the large water tank 14. The ice water flows from the large water tank 14 through the third water pump 603 and point b of the solenoid valve VI 21 to the small heat exchanger 9 inside the motor 7. In the small heat exchanger 9, it exchanges heat with the cooling medium of the motor 7. After flowing out, it enters the small heat exchanger 9 inside the hydraulic device 8 and exchanges heat with the cooling medium inside the hydraulic device 8. After flowing out, it flows back to the large water tank 14 through point p of the solenoid valve V 20, thus forming a cycle and ensuring the normal operation of the motor 7 and the hydraulic device 8.

[0047] When the fire-fighting robot participates in firefighting operations: Under this condition, the internal equipment of the fire-fighting equipment relies on the water source of the internal external pipeline for heat dissipation. At this time, external pipeline valves I23, II24, and III25 are all in the open state. The external water is divided into three branches through the deceleration valve 15 and the distributor 3. The battery pack 2 cooling cycle serves as the power source for the fire-fighting robot. The battery pack 2 requires a low cooling temperature. Therefore, the external water first flows through external pipeline valve I23 to the chiller 1 to further cool the water before flowing through point p of solenoid valve II17 to reach the battery pack 2, absorbing the heat generated by the battery pack 2. It then flows out of the battery pack 2, flows through point a of solenoid valve I16, and returns to the chiller 1 for cooling, thus forming a cycle to ensure the cooling of the battery pack. For the normal operation of 2, excess water flowing through the chiller 1 flows out from the reducer 12 to cool the reducer 12; the cooling of the electrical control cabinet 5 and the water-cooled cover 4 is achieved by the water flowing through the external pipeline valve II 24 to point p of the solenoid valve IV 19 to the water-cooled cover 4, absorbing the heat generated by the sensor inside the water-cooled cover 4 and flowing out, passing through point a of the solenoid valve III 18 and flowing out of the fire robot, thus ensuring the normal operation of the electrical control cabinet 5 and the sensor; the cooling of the motor 7 and the hydraulic device 8 is achieved by the water flowing through the external pipeline valve III 25 to point b of the solenoid valve VI 21 to the small heat exchanger 9 connected to the motor 7 and the hydraulic device 8, exchanging heat with the cooling medium of the motor 7 and the hydraulic device 8 and flowing out, passing through point a of the solenoid valve V 20 and flowing out, further ensuring the normal operation of the motor 7 and the hydraulic device 8.

[0048] When the fire-fighting robot operates in a non-fire environment: Under this condition, the heat dissipation of the internal equipment and the amount of external heat radiation are low. At this time, the installed fan 11 can fully meet the heat dissipation requirements of the whole machine. At this time, the external pipeline valves I 23, II 24, and III 25 are all in the closed state. The states of solenoid valves I 16, II 17, III 18, IV 19, V 20, and VI 21 are all consistent with the states when the fire-fighting robot participates in fire-fighting operations. Thus, the external water circulation pipeline and the internal cooling medium circulation pipeline are both in the closed state. Under this condition, only the fan 11 participates in the heat dissipation of the fire-fighting robot.

[0049] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
