A fire-fighting robot for use in chemical industrial parks

Abstract

This invention discloses a fire-fighting robot for use in chemical industrial parks. The robot includes a shell, with wheels for movement fixedly connected to the lower surface of the shell via a universal joint. Inside the shell is a water storage tank, on which a fire-fighting sprayer is mounted. A water storage detection component is installed on the water storage tank, and a retraction component protects the sprayer. The water storage detection component detects and alarms as the water in the tank gradually depletes. The retraction component retracts the sprayer back into the shell for protection. As the water in the tank gradually decreases, the weight on the compression spring gradually decreases, causing the spring to push the tank upwards. When the water in the tank is depleted, a first electrical contact contacts a second electrical contact, activating the circuit and triggering an alarm to indicate that the water in the tank is empty and needs to be refilled, thus achieving automatic water level detection.

Description

Technical Field

[0001] This invention relates to fire fighting in chemical industrial parks, specifically a fire fighting robot applicable to chemical industrial parks. Background Technology

[0002] The chemical industry is an important sector in my country's economic development, playing an increasingly important role in today's society. However, it also faces immense market competition, leading some chemical industrial parks to prioritize economic benefits. Failure to strictly adhere to safety management regulations during the production or handling of chemical raw materials, including unauthorized production operations and open flame work, can cause fires. If not extinguished promptly, these fires can escalate into larger conflagrations, often accompanied by fire and explosion risks. Currently, when fires occur in chemical plants, due to the unique nature of the large quantities of chemical products and hazardous materials involved, fire extinguishing robots are typically used. However, workers cannot directly observe the remaining water content inside the fire extinguishing robot, and they cannot know when the water inside the robot has been depleted. If the fire is not completely extinguished, the fire extinguishing robot may remain trapped in the flames and be damaged.

[0003] Based on this, the present invention designs a fire-fighting robot for use in chemical industrial parks to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a fire-fighting robot applicable to chemical industrial parks, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fire-fighting robot for use in chemical industrial parks, comprising a shell, with wheels for movement fixedly connected to the lower surface of the shell via a universal joint, a water storage tank inside the shell, a fire-fighting sprayer mounted on the water storage tank, a water storage detection component mounted on the water storage tank, and a retraction component for protecting the sprayer mounted on the sprayer. The water storage detection component detects and alarms when the water in the water storage tank is gradually consumed, and the retraction component can retract the sprayer back into the shell for protection.

[0006] As a further embodiment of the present invention, the water storage detection component includes a compression spring, which is fixed between the water storage cylinder and the inner wall of the bottom end of the shell. Fixing plates are fixedly connected to both sides of the water storage cylinder. A first electrical contact is fixedly connected to the fixing plate. A second electrical contact for electrical connection is provided directly above the electrical contact. The second electrical contact is fixedly connected to the inner wall of the shell.

[0007] As a further embodiment of the present invention, the shrinking assembly includes two first racks fixedly connected to the inner walls of both sides of the water storage tank. The first racks are engaged with first gears. The first gears are rotatably connected to fixed blocks. The fixed blocks are fixedly connected to second electrical contacts. A winding wheel is fixedly connected to the shaft of the first gears. A first traction rope is wound around the winding wheel. A fixed frame is fixedly connected to the upper end of the first traction rope. A fixed ring is fixedly connected to the fixed frame. A water outlet pipe is fixedly connected to the shaft of the fixed ring. The upper end of the water outlet pipe is fixedly connected to a sprayer. The lower end of the water outlet pipe is rotatably connected to the fixed ring. A turbine blade is fixedly connected to the lower end of the fixed ring. A return spring is fixedly connected between the fixed ring and the water storage tank.

[0008] As a further aspect of the present invention, the compression spring is in a compressed state when the water storage cylinder is full of water.

[0009] As a further embodiment of the present invention, the length of the two fixing brackets is greater than the diameter of the water storage cylinder.

[0010] As a further embodiment of the present invention, the lower surface of the second electrical contact is provided with a groove that is adapted to the first electrical contact. When energized, the first contact is electrically connected to the electrical piece in the groove of the second electrical contact.

[0011] As a further aspect of the present invention, the sprayer is provided with multiple spray holes, which can spray water from all directions to extinguish the fire during operation.

[0012] As a further embodiment of the present invention, the upper end of the housing is provided with an inlet hole adapted to the sprayer, so that the sprayer can be easily retracted into the housing during operation.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Through the coordinated use of the first gear, the winding reel, and the first traction rope, the sprayer is driven to gradually move downwards via the water outlet pipe. The remaining water level in the storage tank can be determined based on the height of the sprayer on the housing to observe whether there is enough water left in the storage tank to extinguish any remaining fire. If there is not enough water in the storage tank to extinguish the remaining fire, another unit of this device will be arranged to take over. The unit that has used up its water will return to refill its water tank and extinguish the fire again until the fire is completely extinguished.

[0015] 2. As the water in the storage tank is gradually consumed, the weight borne by the compression spring gradually decreases, and the compression spring gradually pushes the storage tank upward. When the water in the storage tank is completely consumed, the first electrical contact and the second electrical contact make contact, the circuit is connected, and the device emits an alarm sound to indicate that the water in the storage tank is used up and needs to be refilled, thus achieving the effect of automatic water level detection.

[0016] 3. The water storage tank drives the first rack to rotate, which in turn drives the first gear. The rotation of the first gear causes the winding wheel to rotate, which in turn winds up the first traction rope. The winding of the first traction rope causes the fixing frame to move down, and the lowering of the fixing frame gradually moves the sprayer down, causing the sprayer to retract into the housing. This can protect the sprayer from burning if the fire is not completely extinguished when the water in the water storage tank is used up. It also prevents dust from accumulating on the sprayer during daily storage, thus avoiding dust affecting the use of the sprayer.

[0017] 4. When water is pumped upward through the outlet pipe, the water flow drives the turbine blades to rotate. The turbine blades can filter out impurities that accidentally enter the water in the storage tank, preventing them from being pumped into the outlet pipe and clogging it. This would affect the water output of the sprayer, which could lead to the inability to extinguish the fire in time when it breaks out in the chemical plant, and the fire could further intensify, causing unnecessary losses to the chemical plant.

[0026] Please see Figure 1-6This invention provides a technical solution: a fire-fighting robot for use in chemical industrial parks, comprising a shell 1, with a rotating wheel 2 for movement fixedly connected to the lower surface of the shell 1 via a universal joint 10. A water storage tank 3 is disposed inside the shell 1, and a fire-fighting sprayer 16 is disposed on the water storage tank 3. A water storage detection component is disposed on the water storage tank 3, and a retraction component for protecting the sprayer 16 is disposed on the sprayer 16. The water storage detection component detects and alarms when the water in the water storage tank 3 is gradually consumed, and the retraction component can retract the sprayer 16 back into the shell 1 for protection.

[0027] As a further embodiment of the present invention, the water storage detection component includes a compression spring 4, which is fixed between the water storage cylinder 3 and the inner wall of the bottom end of the housing 1. Fixing plates 5 are fixedly connected to both sides of the water storage cylinder 3. A first electrical contact 6 is fixedly connected to the fixing plate 5. A second electrical contact 19 for electrical connection is provided directly above the electrical contact 6. The second electrical contact 19 is fixedly connected to the inner wall of the housing 1.

[0028] During work: (e.g.) Figure 1 As shown in the diagram, the water storage tank 3 is filled with water that needs to be extinguished. When a fire breaks out in a corner of the chemical industrial park, this device is activated to extinguish the fire at the designated point. Then, the sprayer 16 is activated to pump the water in the water storage tank 3 out through the outlet pipe 14 for fire extinguishing. Since the spray holes 21 are arranged in a circular array on the sprayer 16, the sprayer 16 can extinguish the fire from all directions without adjusting the position of the sprayer 16. This avoids the time spent adjusting the position of the sprayer 16, which could lead to the fire not being controlled in time and further increasing in size.

[0029] As the water in the water tank 3 is gradually consumed, the weight borne by the compression spring 4 gradually decreases, and the compression spring 4 gradually pushes the water tank 3 upward. When the water in the water tank 3 is completely consumed, the first electrical contact 6 and the second electrical contact 19 come into contact, the circuit is connected, and the device emits an alarm sound, indicating that the water in the water tank 3 is used up and needs to be refilled, thus achieving the effect of automatically detecting the water level.

[0030] As a further embodiment of the present invention, the shrinking assembly includes two first racks 7 fixedly connected to the inner walls of both sides of the water storage cylinder 3. The first racks 7 are engaged with a first gear 8. The first gear 8 is rotatably connected to a fixing block 11. The fixing block 11 is fixedly connected to a second electrical contact block 19. A winding wheel 9 is fixedly connected to the shaft of the first gear 8. A first traction rope 12 is wound around the winding wheel 9. A fixing frame 13 is fixedly connected to the upper end of the first traction rope 12. A fixing ring 20 is fixedly connected to the fixing frame 13. A water outlet pipe 14 is fixedly connected to the shaft of the fixing ring 20. The upper end of the water outlet pipe 14 is fixedly connected to a sprayer 16. A fixing ring 17 is rotatably connected to the lower end of the water outlet pipe 14. A turbine blade 18 is fixedly connected to the lower end of the fixing ring 17. A return spring 15 is fixedly connected between the fixing ring 20 and the water storage cylinder 3.

[0031] During operation: As the water in the storage tank 3 is gradually consumed, the weight borne by the compression spring 4 gradually decreases, and the compression spring 4 gradually pushes the storage tank 3 upward. The storage tank 3 drives the first rack 7 to rotate, which in turn drives the first gear 8 to rotate. The first gear 8 rotates, and the winding wheel 9 rotates, winding up the first traction rope 12. The winding of the first traction rope 12 causes the fixing frame 13 to move downward. After the fixing frame 13 moves downward, the sprayer 16 gradually moves downward, causing the sprayer 16 to retract into the housing 1. This can protect the sprayer 16 from burning if the fire is not completely extinguished when the water in the storage tank 3 is used up. It can also be used for daily storage. To prevent dust accumulation in the sprayer 16 and its impact on its use, and because the water in the water tank 3 is gradually consumed, the sprayer 16 is gradually lowered via the water outlet pipe 14 through the cooperation of the first gear 8, the winding wheel 9, and the first traction rope 12. The remaining water in the water tank 3 can be judged based on the height of the sprayer 16 on the housing 1 to observe whether there is enough water left in the water tank 3 to extinguish any remaining fire. If there is not enough water in the water tank 3 to extinguish the remaining fire, another device is arranged to take over. The device that has used up its water returns to refill the water tank and extinguishes the fire again until the fire is completely extinguished.

[0032] When water is pumped upward through the outlet pipe 14, the water flow will drive the turbine blades 18 to rotate. The turbine blades 18 can filter impurities that accidentally enter the water in the water storage tank 3, preventing them from being pumped into the outlet pipe 14 and clogging it. This would affect the water output of the sprayer 16, thus preventing the chemical plant from being able to extinguish the fire in time and causing the fire to intensify, resulting in unnecessary losses to the chemical plant and preventing more casualties among the workers.

[0033] As a further embodiment of the present invention, the compression spring 4 is in a compressed state when the water storage cylinder 3 is full of water.

[0034] As a further embodiment of the present invention, the length of the two fixing brackets 13 is greater than the diameter of the water storage cylinder 3.

[0035] As a further embodiment of the present invention, the lower surface of the second electrical contact 19 is provided with a groove that is adapted to the first electrical contact 6. When energized, the first contact 6 is electrically connected to the electrical piece in the groove of the second electrical contact 19.

[0036] As a further embodiment of the present invention, the sprayer 16 is provided with a plurality of spray holes 21. When in operation, the plurality of spray holes 21 can spray water from all directions in 360 degrees to extinguish the fire.

[0037] As a further embodiment of the present invention, the upper end of the housing 1 is provided with an inlet hole adapted to the sprayer 16, so that the sprayer 16 can be easily retracted into the housing 1 during operation.

[0038] Working principle: (e.g.) Figure 1 As shown in the diagram, the water storage tank 3 is filled with water that needs to be extinguished. When a fire breaks out in a corner of the chemical industrial park, this device is activated to extinguish the fire at the designated point. Then, the sprayer 16 is activated to pump the water in the water storage tank 3 out through the outlet pipe 14 for fire extinguishing. Since the spray holes 21 are arranged in a circular array on the sprayer 16, the sprayer 16 can extinguish the fire from all directions without adjusting the position of the sprayer 16. This avoids the time spent adjusting the position of the sprayer 16, which could lead to the fire not being controlled in time and further increasing in size.

[0039] As the water in the water tank 3 is gradually consumed, the weight borne by the compression spring 4 gradually decreases, and the compression spring 4 gradually pushes the water tank 3 upward. When the water in the water tank 3 is completely consumed, the first electrical contact 6 and the second electrical contact 19 come into contact, the circuit is connected, and the device emits an alarm sound, indicating that the water in the water tank 3 is used up and needs to be refilled, thus achieving the effect of automatically detecting the water level.

[0040] As the water in the water tank 3 is gradually consumed, the weight borne by the compression spring 4 gradually decreases, and the compression spring 4 gradually pushes the water tank 3 upward. The water tank 3 drives the first rack 7 to rotate, which in turn drives the first gear 8 to rotate. The first gear 8 rotates, and the winding wheel 9 rotates, winding up the first traction rope 12. The winding of the first traction rope 12 causes the fixing frame 13 to move downward. After the fixing frame 13 moves downward, the sprayer 16 gradually moves downward, causing the sprayer 16 to retract into the housing 1. This can prevent the sprayer 16 from being burned when the water in the water tank 3 is used up and the fire point is not completely extinguished. This protects the sprayer 16 and also avoids damage during daily storage. Dust accumulates in the sprayer 16 to prevent it from affecting its use. In addition, since the water in the water tank 3 is gradually consumed, the sprayer 16 is gradually lowered by the cooperation of the first gear 8, the winding wheel 9 and the first traction rope 12 through the water outlet pipe 14. The remaining water in the water tank 3 can be judged according to the height of the sprayer 16 on the housing 1 to see if there is enough water left in the water tank 3 to extinguish the remaining fire. If there is not enough water in the water tank 3 to extinguish the remaining fire, the next device is arranged to take over. The device that has used up the water returns to refill the water and extinguishes the fire again until the fire is completely extinguished.

[0041] When water is pumped upward through the outlet pipe 14, the water flow will drive the turbine blades 18 to rotate. The turbine blades 18 can filter impurities that accidentally enter the water in the water storage tank 3, preventing them from being pumped into the outlet pipe 14 and clogging it. This would affect the water output of the sprayer 16, thus preventing the chemical plant from being able to extinguish the fire in time and causing the fire to intensify, resulting in unnecessary losses to the chemical plant and preventing more casualties among the workers.
