Description

Technical Field

[0001] This utility model belongs to the field of emergency robot technology, specifically, it relates to an amphibious emergency robot that facilitates the position adjustment of a drainage pump. Background Technology

[0002] In emergency rescue operations, amphibious emergency robots, with their adaptability to complex aquatic and terrestrial environments, have become key equipment for tasks such as flood drainage and water rescue. These robots typically integrate a powered locomotion mechanism (such as multi-terrain adaptive wheels), a control module, and a work unit, enabling them to autonomously or remotely enter dangerous flooded areas. Drainage operations rely on onboard drainage pumps, which, as core functional components, must efficiently remove floodwater and small debris (such as mud and branches) to ensure rapid removal of water from the area, thus aiding rescue and subsequent recovery efforts.

[0003] Currently, the drainage pumps in amphibious emergency robots are mostly installed in fixed or simple connection structures, which are difficult to meet the needs of diverse working conditions. The fixed installation of drainage pumps cannot be flexibly adjusted. When facing different water depths, the drainage efficiency may be low because the pump end cannot adapt to the depth (e.g., the pump end cannot reach the effective water level in deep water, and it is easy to hit the bottom and be damaged in shallow water). When operating in complex terrain (such as in the presence of obstacles or slopes), the fixed drainage pump is prone to collision with the environment, which not only damages the equipment, but also interrupts the drainage operation and delays the rescue opportunity. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an amphibious emergency robot that can overcome or at least partially solve the above problems and facilitate the position adjustment of the drainage pump.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an amphibious emergency robot that facilitates the position adjustment of a drainage pump, comprising an amphibious robot, wherein the chassis of the amphibious robot has an installation groove for mounting a drainage pump body, the drainage end of the drainage pump body is equipped with a pipe connector for connecting to a water pipe, and further comprising: a first support frame, sleeved on the drainage pump body near the pipe connector, the two sides of the first support frame being rotatably connected to the wall of the installation groove via rotating shafts; a second support frame, sleeved on the drainage pump body near the pumping end; and a waterproof hydraulic telescopic cylinder, rotatably connected to the top of the installation groove, the telescopic end of the waterproof hydraulic telescopic cylinder being rotatably connected to the second support frame.

[0006] To facilitate buffering and protecting the drainage pump body, a groove is further provided on the side wall of the mounting slot near the first support frame. A slider is slidably connected in the groove. The rotating shaft on the first support frame is rotatably connected to the slider on the same side. Buffer springs are symmetrically fixedly connected to the upper and lower sides of the slider. The side of the buffer spring away from the slider is fixedly connected to the groove wall. A buffer rubber ring is provided between the inner wall of the second support frame and the drainage pump body. The buffer rubber ring is fixedly connected to the second support frame.

[0007] To facilitate increased drainage capacity, two drainage pump bodies are symmetrically arranged, with two installation ports for use with the drainage pump bodies on both the first and second support frames.

[0008] To facilitate the simultaneous suction of small impurities and reduce the risk of blockage and short circuit, the drainage pump body is further described as a hydraulic slurry pump.

[0009] To facilitate the interception of larger impurities in the drainage pump body, a filter screen is further installed at the pumping end of the drainage pump body.

[0010] To facilitate quick assembly and disassembly of the filter screen, a threaded ring is further provided at the pumping end of the drainage pump body, and the filter screen is fixedly connected to the threaded ring.

[0011] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through the adjustment mechanism composed of a waterproof hydraulic telescopic cylinder, a first support frame, a second support frame, etc., can flexibly adjust the position of the pumping end of the drainage pump body. Facing different water depth conditions, such as deep water accumulation areas, the pumping end can be inserted into the water for efficient water pumping, while shallow water areas or areas with obstacles can be moved upward to avoid them, adapting to various complex water accumulation environments and solving the problem that fixed-position drainage pumps are difficult to adapt to different working conditions.

[0012] Because the pumping end position can be adjusted, the drainage pump body is always in the optimal pumping posture. Whether pumping deep water, water containing impurities, or dynamically adjusting when the water depth changes, it can ensure stable and efficient drainage, reduce pumping difficulties and pump idling caused by unsuitable position, and improve the efficiency of emergency drainage operations.

[0013] The position of the drainage pump can be adjusted according to the working conditions to avoid collisions and damage caused by improper pump positioning in shallow water or areas with obstacles. At the same time, reasonable position adjustment reduces unnecessary wear on the pump (such as idling, overload, etc.), protects the drainage pump and related components of the amphibious robot, and extends the overall service life of the equipment.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] Example 1:

[0023] Reference Figures 1-4 An amphibious emergency robot for easy adjustment of the position of a drainage pump includes an amphibious robot 1. The chassis of the amphibious robot 1 has an installation groove 101 for mounting a drainage pump body 2. The drainage end of the drainage pump body 2 is equipped with a pipe connector 201 for connecting to a water pipe. The robot also includes: a first support frame 3, which is sleeved on the drainage pump body 2 near the pipe connector 201. The two sides of the first support frame 3 are rotatably connected to the groove wall of the installation groove 101 via pivots; a second support frame 4, which is sleeved on the drainage pump body 2 near the pumping end; and a waterproof hydraulic telescopic cylinder 5, which is rotatably connected to the top of the installation groove 101. The telescopic end of the waterproof hydraulic telescopic cylinder 5 is rotatably connected to the second support frame 4.

[0024] The drainage pump body 2 is a hydraulic slurry pump.

[0025] The amphibious robot 1 has the ability to operate on both land and water. The mounting slot 101 of its chassis provides installation space for the drainage pump body 2. Through its own power and walking mechanism (such as wheels, the figure shows that the wheel structure adapts to complex terrain), it can move in different environments such as land and water to reach the designated work area.

[0026] The drainage pump body 2 is a hydraulic slurry pump. It uses hydraulic power to drive the impeller to rotate, creating negative pressure inside the pump. This sucks in accumulated water, small particles, branches, mud, etc., and discharges them through the pipe joint 201 at the drainage end. This can greatly reduce the risk of short circuit in the drainage pump body 2, so that the robot can effectively and quickly drain the water when it reaches the water accumulation area.

[0027] Control Principle: The control system (which can be integrated into the control module of the amphibious robot 1) combines environmental information fed back by sensors (such as sensors for detecting water depth and terrain, which are not explicitly mentioned in the attached diagram, but are common configurations for the amphibious robot 1 to achieve intelligent adjustment and are known to those skilled in the art). The system sends commands to the waterproof hydraulic telescopic cylinder 5 to control its telescopic movement. At the same time, it can control the start and stop, speed, etc. of the drainage pump body 2 to complete the drainage operation in a coordinated manner.

[0028] The specific usage process is as follows: First, confirm whether the power system, walking mechanism, and control system of the amphibious robot 1 are normal, whether the drainage pump body 2 is damaged, whether the connection of the pipe joint 201 is well sealed, whether the hydraulic oil of the waterproof hydraulic telescopic cylinder 5 is sufficient and leak-free, and whether each rotating connection is flexible and reliable. Then, based on the terrain, water depth distribution, and other information of the water accumulation area, the robot's navigation system can be used to plan the path from the starting point to the work area and determine the locations that need to be drained.

[0029] The amphibious robot 1 relies on its wheels and other walking mechanisms to travel on land according to a planned path. It uses its obstacle-crossing ability (the wheel structure is adapted to complex terrain) to cross obstacles such as potholes and steps, approach the edge of the water accumulation area, and when it enters the water accumulation area, the robot moves on the water surface or in shallow water area by virtue of its amphibious characteristics. It uses sensors to monitor water depth and terrain changes in real time, adjusts its walking posture, and smoothly reaches the target drainage position.

[0030] Upon reaching the target location, the control system obtains the current position information of the pumping end of the drainage pump body 2, as well as the surrounding water depth and terrain data, through sensors (such as the position sensor installed in the mounting slot 101 or the robot chassis, and the water depth sensor), and determines whether the position needs to be adjusted.

[0031] When the position of the pumping end of the drainage pump body 2 needs to be adjusted, the control system sends a telescopic command to the waterproof hydraulic telescopic cylinder 5. If the pumping end is to be moved down (e.g., to pump water more efficiently in deeper water), the waterproof hydraulic telescopic cylinder 5 extends, and its telescopic end pushes the second support frame 4. Since the two sides of the first support frame 3 are rotatably connected to the wall of the mounting groove 101 through a rotating shaft, the drainage pump body 2 uses the rotatable connection point between the first support frame 3 and the mounting groove 101 as the fulcrum to swing the pumping end downward, approaching or contacting water at different depths. If the pumping end is to be moved up (e.g., to avoid damage to the pump body in shallow water areas, or to adjust the position after clearing obstacles), the waterproof hydraulic telescopic cylinder 5 retracts, pulling the second support frame 4, causing the pumping end of the drainage pump body 2 to swing upward, away from the danger zone or adjusted to a suitable height.

[0032] During the adjustment process, the first support frame 3 is sleeved on the drainage pump body 2, and the second support frame 4 is also sleeved on the drainage pump body 2. The two work together to ensure that the drainage pump body 2 is stable during swing adjustment, and the rotating shaft and the rotating connection structure ensure smooth adjustment.

[0033] After the position is adjusted to the correct position, the control system starts the drainage pump body 2. The pump body uses the principle of hydraulic slurry pump to suck up the accumulated water and impurities from the pumping end and discharge them through the pipe joint 201 at the drainage end. During operation, the system continuously monitors the water depth changes and the pump body's working status (such as flow rate and pressure) through sensors. If the water depth changes or the working conditions change due to obstacles, the above adjustment steps are repeated to dynamically adjust the position of the pumping end of the drainage pump body 2 to ensure drainage efficiency.

[0034] When the water reaches the target depth (such as nearing full drainage or reaching a safe water level), or after the drainage task in the designated area is completed, the control system first shuts down the drainage pump body 2 to prevent it from running dry and causing damage. Then, it controls the waterproof hydraulic telescopic cylinder 5 to move and reset the pumping end of the drainage pump body 2 to the initial safe position (such as storing it in the installation slot 101 at a suitable height to facilitate land movement and protect the pump body). Then, the amphibious robot 1 returns from the waterlogged area according to the planned path or a new evacuation path to complete the operation.

[0035] The adjustment mechanism, consisting of a waterproof hydraulic telescopic cylinder 5, a first support frame 3, and a second support frame 4, allows for flexible adjustment of the pumping end position of the drainage pump body 2. It can be used to handle different water depths, such as deep water accumulation areas where the pumping end can be inserted into the water for efficient pumping, and shallow water areas or areas with obstacles where the pumping end can be moved upwards to avoid them. This adapts to various complex water accumulation environments and solves the problem that fixed-position drainage pumps are difficult to adapt to different working conditions.

[0036] Because the pumping end position can be adjusted, the drainage pump body 2 is always in the optimal pumping posture. Whether pumping deep water, water containing impurities, or dynamically adjusting when the water depth changes, it can ensure stable and efficient drainage, reduce pumping difficulties and pump idling caused by unsuitable position, and improve the efficiency of emergency drainage operations.

[0037] The position of the drainage pump body 2 can be adjusted according to the working conditions to avoid collisions and damage caused by improper pump body position in shallow water areas or areas with obstacles. At the same time, reasonable position adjustment reduces unnecessary wear of the drainage pump body 2 (such as idling, overload, etc.), protects the drainage pump body 2 and related components of the amphibious robot 1, and extends the overall service life of the equipment.

[0038] Example 2:

[0039] Reference Figures 1-4 An amphibious emergency robot that facilitates the position adjustment of a drainage pump is basically the same as in Embodiment 1, but with the following additional features: a groove 102 is provided on the side wall of the mounting groove 101 near the first support frame 3, and a slider 301 is slidably connected in the groove 102. The pivot on the first support frame 3 is rotatably connected to the slider 301 on the same side. Buffer springs 302 are symmetrically fixedly connected to the upper and lower sides of the slider 301. The side of the buffer spring 302 away from the slider 301 is fixedly connected to the groove wall of the groove 102. A buffer rubber ring is provided between the inner wall of the second support frame 4 and the drainage pump body 2, and the buffer rubber ring is fixedly connected to the second support frame 4.

[0040] During the movement of the amphibious robot 1, the unevenness of the ground will generate vibrations that are transmitted to the chassis. When the vibration causes the drainage pump body 2 to show a slight tendency to change position, the first support frame 3 drives the rotating shaft, which in turn causes the slider 301 to slide in the groove 102. At this time, the upper and lower symmetrical buffer springs 302 can absorb the vibration energy through their own elastic deformation, and play a buffering role on the slider 301 and the first support frame 3 and the drainage pump body 2 connected to it, reducing the direct impact of vibration on the drainage pump body 2.

[0041] The buffer rubber ring between the inner wall of the second support frame 4 and the drainage pump body 2 utilizes the elasticity and flexibility of the rubber material to effectively buffer the collision and compression between the drainage pump body 2 and the second support frame 4 when the robot moves and vibrates. The buffer rubber ring absorbs energy through its own deformation, which can effectively reduce the damage caused by hard contact. For example, when the robot is traveling on bumpy land or moving on wavy water, vibration will continue to be generated. The buffer spring 302 and the buffer rubber ring can continuously play a buffering role, maintain the relatively stable posture of the drainage pump body 2, and avoid the loosening and damage of the internal components of the pump body due to frequent and severe vibration, thus ensuring the structural integrity and long-term reliable operation of the drainage pump body 2.

[0042] If a damper is required (it can be set between the slider 301 and the groove 102, at the buffer rubber ring, or at other suitable locations), the damper can work in conjunction with the buffer spring 302 and the buffer rubber ring. The damper can convert vibration energy into heat energy and dissipate it through the viscous resistance of the internal damping medium, further suppressing the transmission and amplification of vibration. During the continuous vibration process of the robot's movement, the buffer spring 302 is responsible for initially absorbing vibration energy, while the damper can slow down the reciprocating vibration of the spring, avoiding secondary vibration damage to the drainage pump body 2 caused by the continuous rebound of the spring, and enhancing the protection of the drainage pump body 2.

[0043] Example 3:

[0044] Reference Figures 1-4 An amphibious emergency robot with easily adjustable drainage pump position is basically the same as in Embodiment 2, but with a further improvement: two drainage pump bodies 2 are symmetrically arranged, and two installation ports for use with drainage pump bodies 2 are opened on the first support frame 3 and the second support frame 4. The two drainage pump bodies 2 work together, and the drainage flow rate can be greatly increased compared with a single pump body. In emergency flood drainage and other scenarios, the water depth can be reduced more quickly and the operation time can be shortened. Especially when facing large areas and deep water accumulation areas, the parallel operation of the two pumps can significantly enhance the drainage efficiency and meet the needs of emergency tasks for rapid drainage. When one of the drainage pump bodies 2 fails to work due to a malfunction (such as debris jamming or component damage), the other pump body can continue to operate and maintain basic drainage function, effectively improving the reliability of the robot's drainage operation, avoiding the complete interruption of the drainage task due to a single pump failure, and ensuring the continuity of emergency operations.

[0045] An intercepting filter 202 is installed at the water intake end of the drainage pump body 2. When the amphibious emergency robot performs drainage tasks, the water environment is often mixed with branches, large debris, and blocky garbage. The intercepting filter 202 at the water intake end of the drainage pump body 2 can directly physically intercept these larger impurities. For example, in urban flooding scenarios, the water may carry fallen branches and fragments of discarded building materials. The filter can block them outside the pump body in the first instance, preventing debris from entering the pump body and causing blockage of the water intake channel, ensuring a smooth drainage process, and allowing the robot to efficiently complete the water drainage operation. At the same time, if larger impurities enter the drainage pump body 2, they will cause serious damage to key internal components such as the impeller and pump chamber. For example, branches wrapped around the impeller may cause the impeller to jam, the motor to overload, or even damage the pump body's sealing structure. The intercepting filter 202 reduces such risks from the source by intercepting large particles of impurities in advance, protects the precision components inside the pump body, reduces the probability of failure caused by impurities, significantly extends the service life of the drainage pump body 2, and reduces the cost and time consumption of equipment maintenance and replacement during emergency operations.

[0046] A threaded ring 203 is threadedly connected to the pump body 2 at its intake end. An interceptor filter 202 is fixedly connected to the threaded ring 203. The connection between the pump body 2's intake end and the threaded ring 203 is threaded, requiring no complex tools; the interceptor filter 202 can be installed and removed simply by rotation. During robot assembly, the threaded ring 203, with the interceptor filter 202 fixed to it, can be quickly screwed into the pump body 2's intake end, achieving precise positioning and installation of the filter. During emergency operation breaks or routine maintenance, if it is necessary to clean debris adhering to the filter surface, simply reverse the rotation of the threaded ring 203 to easily remove the filter. The filter screen 202 can be removed from the pump body, which greatly simplifies the operation process and reduces the time cost and difficulty of manual intervention. During long-term use, the filter screen 202 may be damaged or its filtration efficiency may decrease due to impurities impacting or corroding. Since the filter screen 202 is fixed on the threaded ring 203 and the threaded ring 203 is detachably connected to the pump body, when the filter screen needs to be replaced, there is no need to disassemble the drainage pump body 2 itself. Only the threaded ring 203 with the new filter screen needs to be replaced. This not only reduces maintenance procedures but also reduces interference with the core components of the pump body and avoids the risk of damage to the internal structure caused by frequent disassembly and assembly of the pump body.
