Description

Technical Field

[0001] The present invention relates to the application field of fire-fighting equipment, and in particular to a movable waterlogging drainage robot and a waterlogging drainage method. Background Art

[0002] A drainage robot is an automated device used in floods or waterlogging disasters. It is designed to help drain accumulated water quickly and effectively and reduce the damage and losses caused by accumulated water. The design of a drainage robot usually includes a powerful water pump, an automated control system, and the ability to adapt to complex terrain. They can autonomously determine the location of accumulated water, automatically start the drainage process, and monitor water level changes in real time through sensors.

[0003] Drainage robots are mainly used in urban drainage, post-disaster rescue and agricultural irrigation systems. Through a powerful pump body, the accumulated water that forms floods is sucked and transferred to other places, thereby eliminating the harm of floods. In order to adapt to complex terrain, the main body of the drainage robot has high waterproof performance. The key electrical control equipment is made of waterproof components and waterproof coatings. The pump body of the drainage robot is often equipped with pump body self-cleaning equipment, such as self-cleaning impeller, reverse water flow flushing function, etc., to ensure that the pump body always maintains an efficient working state. The drainage robot can be used for fire fighting and fire rescue. The water inlet of the water pump is connected to a fire hydrant or a pipe to the river, and the water outlet is connected to a fire sprinkler gun. However, in most cases, the drainage robot is used to deal with waterlogging on urban roads, such as flooding in underground garages in residential areas.

[0004] In practical applications, there are usually two designs for the water inlet of a drainage robot. One is a straight pipe, whose water inlet is parallel to the ground. This straight pipe is located at a relatively high height of about 1m-1.5m. It is usually connected to an external soft water pipe. The other end of the external soft water pipe is placed in the accumulated water to start suction. It can pump water over a long distance. Since the height of the straight pipe matches the height of the human body, it is more convenient to connect the straight pipe to an external hose or a fire hose. Another type is a curved pipe, whose water inlet is perpendicular to the ground. Because the curved pipe design makes the water inlet closer to the ground than a straight pipe, the height of this curved pipe is usually set lower to make it easier to pump the accumulated water to a lower height. However, due to the height problem of the curved pipe, the curved pipe is not suitable for use with external water pipes.

[0005] Therefore, in actual applications, drainage robots with curved pipe designs tend to be more inclined to completely pump out accumulated water on urban roads, while drainage robots with straight pipe designs have more comprehensive functions. Connecting external pipes can not only pump water over long distances, but also pump accumulated water to a lower liquid level. However, the application of straight pipes involves the connection and laying of external pipes, which is more troublesome than curved pipes in use. Regardless of whether it is a curved pipe design or a straight pipe design, in order to completely pump out accumulated water on urban roads or accumulated water in community garages due to flooding, the water inlets used by both to contact the accumulated water need to be placed at the bottom of the accumulated water, which makes it easy for the pump body to suck up more silt and become blocked. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide a movable drainage robot and a drainage method to solve the technical problems mentioned in the above background.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a movable drainage robot, comprising two groups of crawler drive systems, a mounting frame is arranged between the two groups of crawler drive systems, and a water pump is installed on the top of the mounting frame, and a water inlet is provided on one side of the water pump, the water inlet is connected to a movable water inlet pipe by providing a soft water pipe, the movable water inlet pipe comprises a fixed plate, and one side of the fixed plate is rotatably connected to a sleeve, and a gear is installed on the outside of the sleeve, a mounting plate is provided at the end of the sleeve, and a first pipe and a second pipe are provided on the side of the mounting plate, a fixed rod is fixedly connected to one side of the fixed plate, and the fixed rod extends through the interior of the first pipe and the second pipe, and a filter assembly is provided at the end of the fixed rod, a lifting assembly and a moving assembly capable of adjusting the height of the movable water inlet pipe are provided on one side of the mounting frame, and a rack for driving the movable water inlet pipe to rotate is provided on the side of the lifting assembly.

[0014] Preferably, a gear is provided in the movable water inlet pipe and a rack is provided on the bottom side of the box body, so that when the movable water inlet pipe descends to the bottom, the gear and the rack engage, which can drive the movable water inlet pipe to flip 90°.

[0015] The present invention is further configured such that the moving assembly includes a moving block threadably connected to the screw rod, the moving block is provided with a limiting groove matching the limiting block, and the top of the limiting groove is configured as an arc-shaped guide surface.

[0016] Preferably, a limiting groove is provided on the side of the movable block, and an arc-shaped guide surface is provided at the end of the limiting groove, so that the limiting block of the movable water inlet pipe can be more easily engaged in the limiting groove, thereby completing the installation of the movable water inlet pipe.

[0018] Preferably, by providing structures such as anti-loosening blocks and pressing blocks, the anti-loosening blocks release the restriction on the limit blocks when the movable assembly rises to the highest point, making it convenient for staff to disassemble and assemble the movable water inlet pipe.

[0019] The present invention is further configured such that an equipment cabinet and a control cabinet are provided on the top of the mounting frame, and a water outlet is provided on the bottom of the water pump.

[0020] Preferably, an equipment cabinet is provided to protect the drive device of the water pump and other structures, and a control cabinet is provided to protect the electrical control program of the drainage robot. The drainage robot as a whole adopts a waterproof design, and key components are coated with protective coating to improve sealing, thereby ensuring the drainage robot's wading ability.

[0021] A method for draining water using a mobile drainage robot, the process of which comprises the following steps: S1: First, the staff activates the crawler drive system of the drainage robot through the control terminal, moves it to the designated work location, connects various water pipes, and activates the lifting component to adjust the height of the moving component according to the height of the accumulated water level, thereby adjusting the movable water inlet pipe to 15cm-20cm below the liquid level; S2: Next, the water pump is started. The water pump sucks the accumulated water through the movable water inlet pipe immersed in the accumulated water and discharges it to other places through the water outlet; S3: When the accumulated water level gradually decreases and the movable water inlet pipe drops to the lowest working height, the gear and rack of the movable water inlet pipe engage with each other, causing the movable water inlet pipe to flip 90° and become perpendicular to the ground. Since the filter component is parallel to the ground, the filter component at this time will play a filtering role, preventing floating impurities from entering the interior of the movable water inlet pipe when the drainage robot is unattended.

[0023] Preferably, by arranging a floating plate assembly and a movable water inlet pipe for movable installation, the drainage equipment can ensure the pumping efficiency and reduce the entry of impurities into the water pump when pumping water over a long distance. The floating plate assembly consists of a floating plate, a filter baffle and a support rod. The movable water inlet pipe is installed about 15cm-20cm below the floating plate, and then as the liquid level drops, the movable water inlet pipe can still be maintained below the liquid level. The support rod has a certain safety height to prevent the movable water inlet pipe from being too close to the accumulated water and mud when it drops to the lowest working height, and the filter baffle can reduce the entry of floating impurities into the water pump.

[0024] In summary, the present invention mainly has the following beneficial effects: The present invention provides a movable water inlet pipe that can be movably lifted and rotated, which can not only ensure the pumping efficiency but also reduce the entry of impurities such as silt and leaves into the water pump. Floating impurities such as leaves and plastic bags can easily cause the water pump to be blocked. A soft water pipe is used to connect the water inlet of the water pump and the movable water inlet pipe. The movable water inlet pipe is adjusted to about 15cm-20cm below the liquid level of the accumulated water by the lifting component, and the height of the movable water inlet pipe is synchronously reduced as the liquid level drops. At this time, the movable water inlet pipe is parallel to the ground, and the filter component does not act as a filter component, ensuring that the water pump can pump water efficiently, and impurities floating on the liquid surface are always located above the movable water inlet pipe and are not easy to enter the interior of the water pump. When the movable water inlet pipe drops to the lowest working height, it will flip 90° to be perpendicular to the ground, which can better suck the accumulated water at a low water level. The filter component will play a filtering role due to the flipping of the movable water inlet pipe. Therefore, even if the drainage equipment is unattended, as the accumulated water level drops to the same level as the movable water inlet pipe, impurities floating on the liquid surface will also be reduced from entering the water pump due to the filtering effect of the filter component.

[0025] The present invention provides a floating plate assembly and a movable water inlet pipe for movable installation, so that the drainage equipment can ensure the pumping efficiency and reduce the entry of impurities into the water pump when pumping water at a long distance. The floating plate assembly is composed of a floating plate, a filter baffle and a support rod. The movable water inlet pipe is installed about 15cm-20cm below the floating plate, and then as the liquid level drops, the movable water inlet pipe can still be maintained at a position below the liquid level. The support rod has a certain safety height to prevent the movable water inlet pipe from being too close to the accumulated water and mud when it drops to the lowest working height, and the filter baffle can reduce the entry of floating impurities into the water pump.

The adjustment of the lifting component 10 is controlled by the feedback data of the liquid level sensor of the drainage robot, such as: HLM-40 / 60 series. At this time, the movable water inlet pipe 9 is parallel to the ground, and the impurities floating on the liquid surface are always located above the movable water inlet pipe 9 and are not easy to enter the water pump 5.

[0033] In the above embodiment, please refer to Figure 2 and Figure 3 The lifting assembly 10 includes a box body 1001 installed on the top of the mounting frame 2, and the interior of the box body 1001 is rotatably connected to a screw rod 1002, and the top of the screw rod 1002 is connected to a driving assembly 1003, and the external thread of the screw rod 1002 is connected to the moving assembly 11. A first guide rod 1004 is provided inside the box body 1001, and the first guide rod 1004 and the moving assembly 11 are movably arranged through it. By setting the lifting assembly 10, the height of the moving assembly 11 can be adjusted, thereby achieving the purpose of adjusting the height of the movable water inlet pipe 9.

[0034] In the above embodiment, please refer to Figure 3 The rack 12 is arranged at the bottom position of the side of the box body 1001, and the rack 12 and the gear 907 are engaged with each other. By arranging the gear 907 in the movable water inlet pipe 9 and arranging the rack 12 on the bottom side of the box body 1001, when the movable water inlet pipe 9 drops to the bottom, the gear 907 and the rack 12 are engaged, which can drive the movable water inlet pipe 9 to flip 90°.

[0035] In the above embodiment, please refer to Figure 4The moving component 11 includes a moving block 1101 threadedly connected to the screw rod 1002, and the moving block 1101 is provided with a limiting groove 1102 that matches the limiting block 902, and the top of the limiting groove 1102 is set as an arc-shaped guide surface 1103. By opening the limiting groove 1102 on the side of the moving block 1101 and setting the arc-shaped guide surface 1103 at the end of the limiting groove 1102, the limiting block 902 of the movable water inlet pipe 9 can be more easily engaged in the limiting groove 1102, thereby completing the installation of the movable water inlet pipe 9.

[0036] In the above embodiment, please refer to Figure 6 The internal movement of the moving block 1101 is penetrated by a second guide rod 1104, and the external sleeve of the second guide rod 1104 is provided with a first spring 1105, one end of the second guide rod 1104 is provided with an anti-loosening block 1106, and the other end of the second guide rod 1104 is provided with a linkage plate 1107, the internal movement of the moving block 1101 is installed with a pressing rod 1108, and one side of the pressing rod 1108 is provided with an inclined guide surface 1109, and the bottom of the pressing rod 1108 is provided with a second spring 1110.

The drainage robot adopts a waterproof design as a whole, and the key components are coated with protective coating to improve the sealing, thereby ensuring the wading ability of the drainage robot.

[0038] A method for draining water using a mobile drainage robot, the process of which comprises the following steps: S1: First, the staff activates the crawler drive system 1 of the drainage robot through the control terminal, moves it to the designated work location, connects various water pipes, activates the lifting component 10 to adjust the height of the moving component 11 according to the height of the accumulated water level, and adjusts the movable water inlet pipe 9 to 15cm-20cm below the liquid level; S2: Next, the water pump 5 is started. The water pump 5 sucks the accumulated water through the movable water inlet pipe 9 immersed in the accumulated water and discharges it to other places through the water outlet 6; S3: When the water level gradually decreases and the movable water inlet pipe 9 drops to the lowest working height, the gear 907 and the rack 12 of the movable water inlet pipe 9 engage with each other, causing the movable water inlet pipe 9 to flip 90° and become perpendicular to the ground. Since the filter assembly 905 is parallel to the ground, the filter assembly 905 at this time will play a filtering role, preventing floating impurities from entering the interior of the movable water inlet pipe 9 when the drainage robot is unattended.

[0039] Second embodiment:

[0040] See also Figure 12 and Figure 13 , a floating plate assembly 13 is movably installed on the side of the movable water inlet pipe 9, and the floating plate assembly 13 includes a floating plate 1301, and a mounting column 1302 matching the limit block 902 is provided at the bottom of the floating plate 1301, and the mounting column 1302 and the limit block 902 are fixed by setting a threaded rod 1303, and a plurality of support rods 1304 are provided at the bottom of the floating plate 1301, and a plurality of filter baffles 1305 are provided at the bottom of the floating plate 1301. By setting the floating plate assembly 13 and the movable water inlet pipe 9 to be movably installed, the drainage equipment can also ensure the pumping efficiency and water reduction when pumping water over a long distance. Less impurities enter the water pump 5. The floating plate assembly 13 consists of a floating plate 1301, a filter baffle 1305 and a support rod 1304, all of which are made of low-density materials, such as plastic, rubber, etc. The movable water inlet pipe 9 is installed about 15cm-20cm below the floating plate 1301, and then as the liquid level drops, the movable water inlet pipe 9 can still remain below the liquid level. The support rod 1304 has a certain safety height to prevent the movable water inlet pipe 9 from being too close to the accumulated water and mud when it drops to the lowest working height, and the filter baffle 1305 can reduce the floating impurities from entering the water pump 5.

[0041] The present invention is used in specific operation: when it is necessary to drain flood water at a short distance, such as water accumulation on roads or in garages of residential areas, the crawler drive system 1 is started to drive the drainage robot to move to the work site, and then the drive component 1003 is started. The drive component 1003 drives the screw 1002 to rotate, and the height of the movable component 11 is adjusted by the screw principle, so that the movable water inlet pipe 9 is adjusted to 15cm-20cm below the liquid level of the accumulated water, and then the water pump 5 is started, and the accumulated water enters the interior of the water pump 5 through the movable water inlet pipe 9. At this time, the movable water inlet pipe 9 is parallel to the ground, and the filter component 905 is parallel to the ground, and the water inlet pipe 9 is parallel to the ground. The filter component 905 does not play a filtering role. Since the movable water inlet pipe 9 is located below the liquid level, floating impurities are not easy to enter the interior of the water pump 5. Therefore, the filter component 905 does not play a filtering role to ensure that the water pump 5 can perform efficient pumping work. The water outlet 6 can be connected to an external water pipe to pump the accumulated water to other places. A liquid level sensor is provided in the drainage robot, such as: HLM-40 / 60 series, which is used to detect the height of the accumulated water level in real time. The data of the water level detected by the liquid level sensor is used to control the drive component 1003, so that the movable water inlet pipe 9 is always located 15cm-20cm below the liquid level of the accumulated water.

[0042] As the water level gradually decreases, the height of the movable water inlet pipe 9 will also gradually decrease. When the movable water inlet pipe 9 drops to the lowest working height, the gear 907 and the rack 12 engage, causing the movable water inlet pipe 9 to flip 90° as a whole. At this time, the movable water inlet pipe 9 is perpendicular to the ground. Due to the flipping of the movable water inlet pipe 9, the filter component 905 plays a filtering role. When the water level drops to the same height as the movable water inlet pipe 9, floating impurities begin to gather towards the movable water inlet pipe 9, and the filter component 905 can prevent impurities from entering the water pump 5.

[0043] When long-distance drainage is required, the driving assembly 1003 is driven to raise the moving assembly 11 to the highest point, and then the pressing rod 1108 is squeezed by the inner wall of the box body 1001, so that the pressing rod 1108 compresses the second spring 1110 into the interior of the moving block 1101, and due to the action of the inclined guide surface 1109 of the pressing rod 1108, the linkage plate 1107 is squeezed, so that the anti-loosening block 1106 compresses the first spring 1105 into the interior of the moving block 1101, and then the movable water inlet pipe 9 loses the restricting effect of the anti-loosening block 1106, and the staff The movable water inlet pipe 9 can be quickly disassembled and installed into the mounting column 1302 of the float assembly 13, and the threaded rod 1303 is rotated to fix it. Then the float assembly 13 and the movable water inlet pipe 9 are placed on the surface of the accumulated water. Under the floating effect of the float plate 1301, the movable water inlet pipe 9 remains below the liquid surface. As the liquid level decreases, the float plate 1301 will fall to the ground first due to the support rod 1304, thereby preventing the movable water inlet pipe 9 from sticking to the ground and sucking in more silt. At the same time, the filter baffle 1305 has a filtering effect on larger impurities.

[0044] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
