Description

Technical Field

[0001] This invention belongs to the field of firefighting robots, and specifically relates to a wirelessly controlled firefighting robot. Background Technology

[0002] Fire is a major threat to human survival. Especially in recent years, frequent fires have caused significant loss of life and property. Generally, disaster relief relies on rescue personnel going to the scene in person. However, in harsh environments such as high temperatures, intense heat, radiation, dense smoke, complex terrain, numerous obstacles, chemical corrosion, and flammable and explosive materials, manual operation presents numerous difficulties and may even fail to achieve the intended tasks. Rescue personnel also face safety hazards when conducting close-range rescue operations in high-temperature, flammable, and explosive environments. Therefore, wirelessly controlled firefighting robots have emerged. These are special robots controlled via a wireless network to replace firefighters in fire rescue operations. They are typically equipped with a mobile base, fire monitor, water collector, connecting pipes, camera, and control system. The fire monitor is used to launch water jets for long-range firefighting and is equipped with a self-sprinkling system for cooling. However, if a large amount of water from these pipes enters the robot's interior, it will affect its normal operation. Therefore, the waterproof sealing performance of firefighting robots has become a key factor affecting their performance.

[0003] There are two main sources of water inside the firefighting robot: First, condensation. Since the robot's body cannot be completely airtight, moisture inevitably enters as water vapor. Under the influence of day-night temperature differences, condensation forms on the inner walls of the robot. If this condensation falls onto electronic components, it can cause short circuits. Second, water leakage. This is because the pipes supplying water to the fire monitors and the sprinkler system pass through the inside of the robot. There is a risk of leakage at pipe joints or along pipe walls. Additionally, insufficient sealing of the enclosure can allow water to enter from the outside. While existing firefighting robots can effectively seal large flow rates of water in the fire monitor and sprinkler systems, they cannot adequately seal small droplets like water vapor during use. This allows moisture to enter the robot as water vapor and condense, damaging internal electronic components and shortening the robot's lifespan. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The present invention provides a wirelessly controlled firefighting robot. The desiccant adsorbs water vapor inside the bottom shell of the firefighting robot and condenses it into liquid water that flows down the inner wall of the water suction cylinder, thereby removing water vapor from the base and preventing damage to the internal electronic components of the robot due to moisture or water immersion, thus effectively improving the service life of the firefighting robot.

[0014] 2. The present invention discloses a wirelessly controlled firefighting robot. Liquid flowing downwards through the suction cylinder falls into a water storage box. As the amount of liquid water collected in the storage box increases, the storage box moves downwards under the action of gravity. Through the cooperation of a slider, a rotating rod, a first helical gear, a second helical gear, a take-up shaft, a take-up reel, an elastic rope, a base plate, a mounting shell, a pay-off reel, a spring, a pay-off shaft, a pull line, a triangular block, a spring, a base plate, and a moving wheel, the liquid water can be automatically discharged and the collection of liquid water can continue. This can be completed mechanically and automatically without the need for electronic components. It has a high degree of automation, can be reused, and has a high utilization rate.

[0015] 3. In this invention, a wirelessly controlled firefighting robot has a water storage tank whose bottom opening only opens after it descends to a certain height, remaining closed otherwise. This effectively prevents external smoke and water vapor from entering the bottom shell during a fire, providing high protection for the components inside the bottom shell and effectively improving the service life of the wirelessly controlled robot. Furthermore, as the water storage tank moves up and down, it drives the rotating rod to rotate. The first and third helical gears mesh to drive the side shaft to rotate, which in turn drives the fan blades to rotate. This effectively dissipates heat from the electronic components inside the bottom shell, and the fan blades do not require an additional motor, thus effectively improving energy utilization.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] Please refer to Figures 1-5. In this embodiment, a wirelessly controlled firefighting robot includes: a firefighting robot 1 and a base shell 2. At least one drying component is installed inside the base shell 2. The drying component includes a water-absorbing cylinder 3. A desiccant 4 is provided on the upper inner wall of the water-absorbing cylinder 3. The desiccant 4 can absorb water vapor inside the base shell 2 of the firefighting robot. As the water vapor accumulates, it forms small droplets that slide down the inner wall formed by the desiccant 4. A cavity 7 is symmetrically opened on the side wall of the water-absorbing cylinder 3. A rotating rod 9 is rotatably installed inside the cavity 7. Two rotating rods 9 are arranged at the front and rear of one side of the cavity 7. Each rotating rod 9 is equipped with a slider 8. A water storage box 5 is provided inside the water-absorbing cylinder 3. One end of the slider 8 passes through the cavity 7 and is fixedly connected to the outer wall of the water storage box 5. A water outlet 6 is opened at the lower end of the water storage box 5. A bottom opening 10 is opened at the lower end of the water-absorbing cylinder 3. An automatic opening and closing component is provided inside, which is used to control the opening and closing of the bottom opening 10. The bottom opening 10 is directly opposite the water outlet 6. The length and width of the bottom opening 10 are both greater than those of the water outlet 5. At least one drain outlet is provided at the lower end of the bottom shell 2, which is directly opposite the bottom opening 10.

[0028] In practical use, firefighters can wirelessly control the fire-fighting robot to extinguish fires using fire monitors. To prevent damage to the internal electronic components of the fire-fighting robot due to moisture or water immersion caused by water vapor, at least one drying component is installed. Specifically, the desiccant 4 adsorbs the water vapor inside the bottom shell 2 of the fire-fighting robot 1 and condenses it into liquid water that flows down the inner wall of the water suction cylinder 3, thus removing the water vapor from the base.

[0029] To move the water storage box 5, the rotating rod 9 rotates. The slider 8 has a through hole in the middle, and five rotating grooves are evenly distributed around the through hole in a circular direction. The rotating rod 9 has five rotating protrusions evenly distributed around its circumference in a circular direction. The rotating rod 9 engages with the slider 8.

[0030] The automatic opening and closing assembly includes a mounting shell 20 located in the middle of the bottom opening 10 and base plates 19 symmetrically arranged on both sides of the mounting shell 20. Side grooves 18 are symmetrically formed on the side walls of the bottom opening 10. One end of the base plate 19 abuts against the mounting shell 20, and the other end extends into the side groove 18 and is fixedly connected to an elastic rope 16. A first helical gear 11 is fixedly installed at the bottom of the rotating rod 9. Mounting grooves 14 are formed at the four corners of the bottom of the water suction cylinder 3. Each mounting groove 14 contains a take-up shaft 13. A take-up reel 15 is fixedly installed at one end of each take-up shaft 13, and a second helical gear 12 is fixedly installed at the other end of each take-up shaft 13 into the cavity 7. The first helical gear 11 meshes with the second helical gear 12. The elastic rope 16 extends into the mounting groove 14 and is fixedly connected to the take-up reel 15. A feed shaft 21 is symmetrically arranged inside the mounting shell 20, and a feed reel 22 is fixedly installed on each feed shaft 21. A non-elastic pull wire 23 is fixedly provided on the top, one end of which is fixedly connected to the base plate 19.

[0031] The wire feeding shaft 21 has springs 24 at both ends.

[0032] The outlet is equipped with an opening and closing component that controls the opening and closing of the outlet.

[0033] Liquid flowing downwards through the suction cylinder 3 falls into the water storage box 5. As the water volume in the storage box 5 increases, the suction cylinder 3 moves downwards under the influence of gravity. Because the rotating rod 9 and the slider 8 are spirally engaged, the rotating rod 9 rotates, thereby driving the first helical gear 11 to rotate. The first helical gear 11 meshes with the second helical gear 12, driving the take-up shaft 13 and the take-up reel 15 to rotate. The take-up reel 15 pulls the elastic rope 16, and the elastic rope 16 pulls the base plate 19. In the initial stage, the force exerted on the base plate 19 by the spring 24 through the non-elastic tension line 23 is greater than the force of the elastic rope 16. Under the influence of gravity, the water storage tank descends, but the base plate 19 does not move, sealing the bottom opening 10 to prevent external smoke and water vapor from entering the bottom shell 2. As the liquid in the water storage tank increases, the water storage tank continues to descend, and the elastic rope 16 exerts a force on the base plate 19. The elasticity increases until it exceeds the spring force of 24.

[0034] The force of plate 19 causes the bottom plate 19 to move into the side groove 18, exposing the bottom opening 10. The outlet opening and closing assembly opens after water is discharged, and liquid water flows quickly from the water storage tank from the outlet 6 to the bottom opening 10, and finally flows out from the water outlet set at the lower end of the bottom shell 2, completing the discharge of liquid water collected in the bottom shell 2. After the water is discharged, the gravity in the water storage box 5 decreases, and under the action of the spring 24, the bottom opening 10 closes, and the water storage box 5 moves upward to continue collecting liquid water. It has a high degree of automation and can be recycled.

[0035] The mounting groove 14 is provided with a guide wheel to guide the elastic rope 16. The guide wheel can guide the elastic rope 16.

[0036] The upper end of the mounting shell 20 is fixedly provided with a triangular block 25. The side wall of the water outlet 6 is symmetrically provided with a sliding groove 28. Each sliding groove 28 is provided with a sealing plate 26. One end of each sealing plate 26 is fixedly connected to a spring 29, and the other end is pressed against each other. The spring 29 is fixedly connected to the side wall of the sliding groove 28. The lower side of the end of the sealing plate 26 that is pressed against each other is provided with a moving wheel 27. The triangular block 25 drives the moving wheel 27 to move to both sides.

[0037] Specifically, the liquid flowing downwards through the suction cylinder 3 falls into the water storage box 5. As the water volume in the storage box 5 increases, the suction cylinder 3 moves downwards under the action of gravity. Because the rotating rod 9 and the slider 8 are spirally engaged, the rotating rod 9 rotates, thereby driving the first helical gear 11 to rotate. The first helical gear 11 meshes with the second helical gear 12, driving the take-up shaft 13 and the take-up reel 15 to rotate. The take-up reel 15 pulls the elastic rope 16, and the elastic rope 16 pulls the base plate 19. In the initial stage, the force exerted on the base plate 19 by the spring 24 through the non-elastic tension line 23 is greater than the force of the elastic rope 16. Under the action of gravity, the water storage tank descends, but the base plate 19 does not move, sealing the bottom opening 10 to prevent external smoke and water vapor from entering the bottom shell 2. As the liquid in the water storage tank increases, the water storage tank continues to descend, and the elastic rope 16 exerts force on the base plate 19. The elastic force increases until it exceeds the force exerted on the base plate 19 by the spring 24. The base plate 19 moves into the side groove 18, exposing the bottom opening 10. When the water tank moves to the inclined side wall of the triangular plate and contacts the moving wheel 27, as the water tank continues to move downward, the moving wheel 27 moves to both sides with the sealing plate 26, exposing the outlet 6. The liquid in the water tank quickly flows from the outlet 6 to the bottom opening 10, and finally flows out from the outlet set at the lower end of the bottom shell 2, completing the discharge of the liquid water collected in the bottom shell 2. After the liquid in the water tank flows out, under the action of the spring 24, the base plate 19 re-seals the bottom opening 10. The elastic rope 16 gives the take-up reel 15 a rotational force, causing the take-up reel 15 and the take-up shaft 13 to rotate, driving the rotating rod 9 to rotate, causing the water storage box 5 to move upward. During the upward movement of the water storage box 5, the moving wheel 27 and the triangular block 25... Separation occurs when the sealing plate 26 blocks the outlet 6 under the action of the spring 29, allowing the collection of liquid water to continue. The liquid collection and discharge in the bottom shell 2 can be repeated without the need for control components, resulting in a high degree of automation.

[0038] In this invention, the water storage box 5 collects more liquid water and moves downwards. Through the cooperation of slider 8, rotating rod 9, first helical gear 11, second helical gear 12, take-up shaft 13, take-up reel 15, elastic rope 16, base plate 19, mounting shell 20, pay-off reel 22, spring 24, pay-off shaft 21, pull line 23, triangular block 25, spring 29, base plate 19, and moving wheel 27, it can automatically discharge the liquid water and continue to collect liquid water. It does not require electronic component control and can be completed mechanically and automatically. It has a high degree of automation, can be reused, and has a high utilization rate. In addition, the bottom opening 10 of the water storage tank in this invention only opens after it has descended to a certain height. Otherwise, it is in a closed state, which effectively prevents external smoke and water vapor from entering the bottom shell 2 in case of fire. It has a high protection effect on the components inside the bottom shell 2 and effectively improves the service life of the wirelessly controlled robot.

[0039] Two feed rollers 22 are symmetrically arranged on one of the feed roller shafts 21.

[0040] A side shaft 31 is rotatably mounted on the side wall of the water suction cylinder 3. One end of the side shaft 31 extends into the cavity 7 and is fixedly mounted with a third helical gear 30. The third helical gear 30 meshes with the first helical gear 11. The other end of the side shaft 31 extends out of the water suction cylinder 3 and is fixedly connected with a fan blade 17.

[0041] Specifically, as the water storage box 5 moves up and down, it drives the rotating rod 9 to rotate. The first helical gear 11 and the third helical gear 30 mesh to drive the side shaft 31 to rotate, which in turn drives the fan blade 17 to rotate. This effectively dissipates heat from the electronic components inside the bottom shell 2. Furthermore, driving the fan blade 17 to rotate does not require an additional motor. The liquid water collected in the water storage box 5 can be automatically collected and discharged. The mechanical automation level is high, which effectively improves energy utilization.
