Description

Technical Field

[0001] This utility model relates to the field of emergency flood drainage technology, specifically an emergency flood drainage operation robot. Background Technology

[0002] Against the backdrop of global climate change, extreme rainfall is becoming more frequent, and floods have become a major threat to urban safety and people's lives and property. Traditional flood control operations mainly rely on manual operation of water pumps and dredging of pipelines, which is not only inefficient and labor-intensive, but also poses great safety risks to workers in flooded and complex terrain scenarios.

[0003] Chinese patent discloses a flood drainage robot (publication number CN214248749U). This patent includes a main body, hydraulic actuators, a water pump, hydraulic pipelines, and a hydraulic power station. The hydraulic power station is externally located on the main body and is connected to the hydraulic pipelines on the main body via an inlet pipe and a first return pipe. The hydraulic pipelines provide hydraulic power to the hydraulic actuators on the main body. The hydraulic pipelines include a second return pipe and an overflow system. The second return pipe connects to the first return pipe, and the overflow system allows the overflow valves of hydraulic actuators requiring overflow to connect to the second return pipe. The main body includes a buoyancy chamber, a base, and a walking mechanism. The base is located at the bottom of the buoyancy chamber. The mechanism is mounted on a base, and the buoyancy chamber has a accommodating notch for at least one water pump. The water pump is driven by a hydraulic actuator to carry out flood discharge operations. When using the above-mentioned device, due to the poor bearing capacity of muddy ground and the wide tracks, the tracked equipment is prone to mud sticking to its surface when walking on muddy ground because of the large contact area, which increases the overall weight of the tracks and causes the tracks to have to overcome greater resistance during rotation. In addition, in complex terrain full of obstacles, the tracks are easily punctured by sharp objects or stuck in gaps, making the equipment unable to move, or even causing the tracks to derail due to uneven force. This not only delays the flood discharge time, but also requires a lot of manpower and resources for repair and rescue. Utility Model Content

[0004] The purpose of this invention is to provide an emergency flood drainage robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An emergency flood drainage robot includes a main shell. A mud pump for pumping mud and water mixtures is fixedly connected to the top of the main shell. A water collection tray for collecting floodwater and accumulated water is fixedly installed below the mud pump. A connecting pipe is fixedly connected to the bottom of the mud pump. The mud pump is fixedly connected to the top of the water collection tray through the connecting pipe. A curved pipe for drainage is fixedly connected to the top of the mud pump. Rollers for conventional ground movement are rotatably connected to the inner cavity of the main shell. Four adaptable support legs are also slidably connected to the inner cavity of the main shell. The bottom of the four support legs is fixedly connected to irregularly shaped support bars for preventing tipping. Through the cooperation of the support legs and irregularly shaped support bars, the device can walk on flood-damaged ruins, wetlands, soft, uneven ground.

[0007] As a further embodiment of this invention, the inner cavity of the water collection tray is fitted with a filter screen for filtering floating debris.

[0008] As a further embodiment of this utility model, the end of the bend away from the sludge pump is fixedly connected to a connecting hose for drainage, and the sewage is discharged to a designated drainage channel or a safe area at a lower elevation through the connecting hose.

[0009] As a further embodiment of this utility model, two dual-head motors for driving the rollers to rotate are fixedly installed in the inner cavity of the main shell. Rollers are fixedly connected to both ends of the two dual-head motors, and belts are rotatably connected to the outer walls of the rollers through the drive wheel.

[0010] As a further embodiment of this utility model, four irregularly shaped plates for limiting the sliding range of the outriggers are fixedly installed in the inner cavity of the main shell. A rotating plate for pushing the outriggers to rise is rotatably connected to the outer wall of the four irregularly shaped plates. A swing rod for pushing the outriggers to swing is rotatably connected to the end of the rotating plate away from the irregularly shaped plates.

[0011] As a further embodiment of this utility model, the inner cavity of the main shell is rotatably connected to a transmission shaft for driving the rotating plate to rotate, and the outer wall of the roller is slidably connected to a friction sleeve for driving the transmission shaft to rotate. The inner cavity of the friction sleeve is coated with an anti-slip coating to increase friction. When the friction sleeve is slidably sleeved on the outer wall of the transmission shaft, the transmission shaft drives the irregular plate to rotate with the friction sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When in use, this invention features rollers that enable high-speed movement on flat ground or in areas with low water levels, thanks to their low rolling resistance. This ensures rapid deployment in the early stages of a flood. Furthermore, by providing four outriggers, the robot can overcome complex terrain such as flood-damaged ruins, wetlands, soft or uneven surfaces. These outriggers, along with the irregularly shaped support bars at the bottom, allow for alternating support gait, enabling the robot to climb and cross ditches, preventing it from sinking into muddy ground or getting stuck in ruins. This ensures the robot can reach areas inaccessible to traditional equipment to perform flood drainage tasks. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4An emergency flood drainage robot includes a main shell 1. A mud pump 2 for pumping mud and water mixtures is fixedly connected to the top of the main shell 1. The mud pump 2 pumps mud and water mixtures from flooded or waterlogged areas, using mechanical power to draw them from a lower to a higher location, thus realizing the functions of pumping water and removing mud during flood drainage operations. A water collection tray 3 for collecting floodwater and water is fixedly installed below the mud pump 2. A connecting pipe 301 is fixedly connected to the bottom of the mud pump 2, and the mud pump 2 is fixedly connected to the top of the water collection tray 3 through the connecting pipe 301, so that the water can be collected by the water collection tray 3. The accumulated water is guided into the mud pump 2 to improve the drainage efficiency. The top of the mud pump 2 is fixedly connected to a bend pipe 5 for drainage. The inner cavity of the main shell 1 is rotatably connected to a roller 6 for normal ground movement. There are four rollers 6 arranged in an array in the inner cavity of the main shell 1. The inner cavity of the main shell 1 is also slidably connected to four support legs 7 for adaptation. The bottom of the four support legs 7 is fixedly connected to a special-shaped support bar 701 for anti-tipping. Through the cooperation of the support legs 7 and the special-shaped support bar 701, the device can move on the ruins, wetlands, soft and uneven ground after floods.

[0022] Please see Figures 2-3 The inner cavity of the water collection tray 3 is fitted with a filter screen 4 for filtering floating objects, and the filter screen 4 filters out impurities such as leaves and plastics to prevent them from entering the mud pump 2 and causing blockage.

[0023] Please see Figures 1-3 The end of the bend 5 away from the sludge pump 2 is fixedly connected to a connecting hose 501 for drainage. The sewage is discharged to a designated drainage channel or a low-lying safe area through the connecting hose 501 to prevent sewage from flowing back or accumulating near the work area. Specifically, the outer wall of the main shell 1 is fixedly connected to a shell 502 for protecting the connecting hose 501. The inner cavity of the connecting hose 501 is rotatably connected to a rotating shaft 503 for winding the connecting hose 501 through a bearing. The outer wall of the main shell 1 is fixedly connected to a motor for driving the rotating shaft 503 to rotate, and the rotating shaft 503 is fixedly connected to the output shaft of the motor. After the work is completed, the rotating shaft 503 can be rotated by driving the motor to wind the loose connecting hose 501 around its outer wall to avoid the problem of tangling and knotting caused by the hose being dragged on the ground, saving storage time and labor costs, and making it convenient to quickly unfold for the next use.

[0024] Please see Figures 3-4Two dual-head motors 601 for driving the rollers 6 to rotate are fixedly installed in the inner cavity of the main housing 1. Rollers 602 are fixedly connected to both ends of the two dual-head motors 601. The outer wall of the rollers 602 is rotatably connected to the drive wheel via a belt 603. Specifically, the inner cavity of the main housing 1 is rotatably connected to the driven wheel via a bearing, and the belt 603 is rotatably connected to the outer wall of the driven wheel. The driven wheel is fixedly connected to the rollers 6. The end of the rollers 6 away from the driven wheel is rotatably connected to the inner cavity of the main housing 1 via a bearing. By driving the two dual-head motors 601, the rollers 602 are driven to rotate, and the four rollers 6 are driven to rotate via the belt 603, ensuring the smooth movement of the device.

[0025] Please see Figures 3-5 The inner cavity of the main shell 1 is fixedly equipped with four irregularly shaped plates 715 for limiting the sliding range of the outriggers 7. The outer walls of the four irregularly shaped plates 715 are rotatably connected to rotating plates 704 for pushing the outriggers 7 to rise. The end of the rotating plate 704 away from the irregularly shaped plates 715 is rotatably connected to a swing rod 705 for pushing the outriggers 7 to swing. The end of the irregularly shaped plate 715 near the swing rod 705 is rotatably connected via a bearing to a rotating sleeve block 706 for limiting the swing rod 705. The swing rod 705 is slidably connected to... Connected to the inner cavity of the rotating sleeve 706, the top of the swing rod 705 is rotatably connected to the outrigger 7 via a pivot. Specifically, two rotating plates 704 are grouped together, and the angles of the two groups of rotating plates 704 are 180° to each other. When one group of rotating plates 704 pushes the corresponding outrigger 7 to lift, the other group of rotating plates 704 simultaneously presses down on the outrigger 7, forming diagonal alternating support, which effectively improves walking stability and avoids tipping due to imbalance of the center of gravity when walking on muddy, soft or uneven ground.

[0026] More specifically, the inner cavity of the irregular plate 715 is provided with a transverse groove 702 for restricting the movement of the support leg 7. The inner cavity of the transverse groove 702 is slidably connected to a locking block 703 for following the sliding of the support leg 7. The support leg 7 is slidably connected to the inner cavity of the locking block 703, so that the support leg 7 slides in a straight line along the transverse groove 702 opened in the inner cavity of the irregular plate 715, avoiding tilting or deviation caused by uneven force during walking, and ensuring the consistency of the robot's movements when walking on complex terrain.

[0027] Please see Figures 3-5 The inner cavity of the main shell 1 is rotatably connected to a drive shaft 707 for driving the rotating plate 704 to rotate. There are four drive shafts 707, and each one passes through the irregular plate 715 and is fixedly connected to the rotating plate 704. The outer wall of the roller 602 is slidably connected to a friction sleeve 708 for driving the drive shaft 707 to rotate. The inner cavity of the friction sleeve 708 is coated with an anti-slip coating to increase friction. When the friction sleeve 708 is slidably sleeved on the outer wall of the drive shaft 707, the drive shaft 707 drives the irregular plate 715 to rotate with the friction sleeve 708.

[0028] Specifically, a limiting strip 709 is fixedly connected to the inner cavity of the main housing 1. A bidirectional threaded shaft 710 is rotatably connected to the top of the limiting strip 709. A motor for driving the bidirectional threaded shaft 710 is fixedly installed in the inner cavity of the main housing 1. The output shaft of the motor is fixedly connected to the bidirectional threaded shaft 710, and the end of the bidirectional threaded shaft 710 away from the motor is rotatably connected to the inner wall of the main housing 1 through a bearing. Two blocking blocks 714 are slidably connected to the outer wall of the bidirectional threaded shaft 710. A triangular push block 711 is fixedly connected to the top of each blocking block 714. A top block 712 is slidably connected to the top of the triangular push block 711. Both ends of the top block 712 are rotatably connected to a movable shaft for pushing the friction sleeve column 7. The inclined rod 713 is rotatably connected to a bearing at its bottom, and is rotatably connected to the outer wall of the friction sleeve 708 via the bearing. When the bidirectional threaded shaft 710 rotates via the drive motor, the two triangular push blocks 711 slide away from the bottom of the top block 712, causing the top block 712 to fall to the top of the blocking block 714. At the same time, the inclined rod 713 pushes the two friction sleeves 708 to slide to both sides and fit onto the outer wall of the drive shaft 707, transmitting the rotational power of the roller 602 to the rotating plate 704, driving the outriggers 7 to lift and move. This allows the device to quickly adapt to complex terrains such as mud and ruins, improving the emergency flood discharge response speed.

[0029] The working principle of this utility model is as follows: when the ground is relatively flat and the water level is low, two double-headed motors 601 can be driven to rotate the rollers 602, and the four rollers 6 can be rotated through the belt 603 to ensure the smooth movement of the device.

[0030] When the ground is rugged and the water level is high, the first step is to drive the bidirectional threaded shaft 710. Simultaneously, the two triangular push blocks 711 slide away from the bottom of the top block 712, causing the top block 712 to fall onto the top of the blocking block 714. At the same time, the inclined rod 713 pushes the two friction sleeves 708 to slide to both sides and fit onto the outer wall of the transmission shaft 707. Then, the two dual-head motors 601 are driven again, causing the roller 602 to rotate. The roller 602 then drives the friction sleeves 708 and the transmission shaft 707 to rotate, causing the transmission shaft 707 to drive a set of rotating plates 704 to rotate. The swing rod 705 then pushes the corresponding support leg 7. During the lifting process, another set of rotating plates 704 simultaneously flips downwards, pushing the swing arm 705 to press down the support leg 7. By continuously repeating the action of diagonal alternating support, the device is moved to the position to be discharged. The connecting hose 501 is then unfolded, and the port of the connecting hose 501 is placed in the drainage channel. The sludge pump 2 is then driven to allow sewage to enter the sludge pump 2 through the water collection pan 3 and enter the inner cavity of the connecting hose 501 through the bend pipe 5. The sewage is then discharged through the connecting hose 501, completing the emergency flood discharge operation. After the operation is completed, the motor is driven again to drive the rotating shaft 503 to wind up and retract the connecting hose 501, making it easy for the robot to evacuate or move to the next work point.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
