Description

Technical Field

[0001] The utility model relates to the technical field of emergency drainage equipment, and specifically to an excavator water pump integrated drainage system that deeply integrates a large-flow water pump system with an excavator to achieve rapid deployment, efficient drainage, and adaptability to multiple scenarios. Background Art

[0002] Flood disasters are characterized by suddenness and destructiveness. Traditional water pumping equipment is difficult to deploy in complex terrain, has low efficiency, and is unable to meet the needs of rapid rescue. Emergency rescue products currently on the market suffer from low mobility, low intelligence, and high risks of disaster resistance and survival. For example, they have poor terrain adaptability, fixed pumping stations must be pre-built and cannot be moved, and trailer pumps are restricted by road conditions, making it difficult to quickly reach the core dangerous locations in disaster areas such as landslides and mud swamps. They also have a low level of intelligence, high reliance on manual labor, lack autonomous decision-making capabilities, and are unable to respond to water level changes in real time. They have low adaptability to harsh rescue environments, and the safety of operators cannot be effectively guaranteed. These shortcomings make it difficult for traditional rescue pumps to meet the needs of efficient rescue in extreme disaster scenarios. Utility Model Content

[0003] The utility model aims to provide an excavator water pump integrated drainage system to solve the limitations of traditional water pumps in complex environments, achieve rapid deployment, efficient drainage, and multi-scenario adaptability, and improve the efficiency and safety of flood control and rescue.

[0004] The technical solution adopted by the utility model is as follows: an excavator water pump integrated drainage system, comprising:

[0005] The excavator body provides the walking chassis, power source and hydraulic system;

[0006] The water pump module is installed at the end of the excavator boom through a mounting bracket and includes a pump body and a hydraulic motor that drives the pump body;

[0007] A water pump mounting bracket, one end of which is hinged to the end of the excavator boom, and the other end is connected to a pitch adjustment mechanism for adjusting the pitch angle of the water pump mounting bracket and the water pump module;

[0008] A hydraulic power coupling system connects the excavator hydraulic circuit and the hydraulic motor. The hydraulic power coupling system includes a main drive circuit and an auxiliary compensation circuit. The main drive circuit directly drives the impeller of the pump body through the hydraulic motor, and the auxiliary compensation circuit compensates for the hydraulic fluctuations caused by the movement of the excavator boom in real time through an accumulator and a pressure sensor.

[0009] Furthermore, the pump body adopts a high-strength aluminum alloy shell and a carbon fiber impeller.

[0010] Furthermore, the pitch adjustment mechanism includes an adjusting cylinder hingedly mounted on the excavator boom, a first connecting rod hingedly connected to the water pump mounting bracket, and a second connecting rod hingedly connected to the excavator boom, and the first connecting rod and the second connecting rod are hingedly connected to the piston rod end of the adjusting cylinder.

[0011] Furthermore, it also includes an intelligent control module, which includes a controller and a water level sensor and a turbidity sensor arranged at the water inlet of the pump body. The water level sensor monitors the water level changes in real time, and the turbidity sensor is used to detect the sand content. The controller dynamically adjusts the water pump speed according to the data collected by the water level sensor and the turbidity sensor.

[0012] Furthermore, it also includes a joint angle encoder group, which is installed on the boom joint of the excavator arm and the rotating shaft of the water pump mounting bracket to collect the angle values ​​of each joint in real time. The controller automatically calculates the water pump entry angle based on the angle value collected by the joint angle encoder group, and controls the pitch adjustment mechanism to perform angle adjustment.

[0013] The beneficial effects of the present invention are:

[0014] (1) High mobility. By utilizing the powerful off-road performance of the excavator, it can quickly reach the core dangerous areas that traditional equipment cannot reach. The hydraulic system of the excavator is used as the power source, and no external power supply is required. It can work anytime and anywhere, is not restricted by power conditions, and can be deployed quickly.

[0015] (2) Save equipment purchase and operation costs. With excavators as the carrier, there is no need to purchase special emergency drainage vehicles or equipment, which reduces equipment purchase costs. At the same time, excavators usually have strong power and can directly provide power support for water pumps. There is no need to configure additional high-power engines or motors, which reduces energy consumption and maintenance costs during equipment operation.

[0016] (3) The intelligent control system realizes multi-source perception, intelligent decision-making and automatic adjustment, reduces human intervention and improves drainage efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0020] like Figure 1 As shown, the excavator water pump integrated drainage system provided in this embodiment deeply integrates the water pump module with the excavator body, innovatively combining the mobility and power of the construction machinery with drainage functions to form a "one machine, multiple uses" emergency rescue solution. The system includes: an excavator body 1, a water pump module, a water pump mounting bracket 5, a pitch adjustment mechanism, and a hydraulic power coupling system.

[0021] The excavator body 1 provides a walking chassis, a power source and a hydraulic system, and is compatible with mainstream excavators of 25-35 tons.

[0022] The water pump module, mounted on the end of the excavator's boom 2 via a mounting bracket, includes a pump body 3 and a hydraulic motor 4 that drives it. The water pump module utilizes a lightweight structural design, with the pump body 3 utilizing a high-strength aluminum alloy casing and a carbon fiber impeller. The overall weight is kept below 300 kg, reducing the load on the boom 2 and improving operational flexibility.

[0023] The water pump mounting bracket 5 serves as the installation base for the water pump module. One side of the bracket is hinged to the end of the excavator boom 2, and the other end is connected to a pitch adjustment mechanism for adjusting the pitch angle of the water pump mounting bracket 5 and the water pump module. The pitch adjustment mechanism supports the water pump at the end of the boom to adjust the pitch angle of ±90° to adapt to complex terrains such as deep pits and steep slopes. In this embodiment, the pitch adjustment mechanism includes an adjusting cylinder 6 hingedly mounted on the excavator boom 2, a first connecting rod 7 hinged to the water pump mounting bracket 5, and a second connecting rod 8 hinged to the excavator boom 2. The first connecting rod 7 and the second connecting rod 8 are hinged together at the piston rod end of the adjusting cylinder 6. The water pump mounting bracket 5 is driven to rotate around the hinge point with the boom 2 by the hydraulic extension and contraction of the adjusting cylinder 6 to achieve pitch angle adjustment.

[0024] This system is directly powered by the excavator's hydraulic system, connecting the excavator's hydraulic circuit with the hydraulic motor 4 via a hydraulic power coupling system to provide driving energy for the water pump module. In this embodiment, the hydraulic power coupling system includes a main drive circuit and an auxiliary compensation circuit. The main drive circuit directly drives the impeller of the pump body 3 through the hydraulic motor 4. The auxiliary compensation circuit uses an accumulator and pressure sensor to compensate for hydraulic fluctuations caused by the movement of the excavator's boom 2 in real time, ensuring stable operation of the water pump.

[0025] This embodiment also integrates intelligent control technology, including an intelligent control module consisting of a controller, a water level sensor, a turbidity sensor, and a joint angle encoder group. The water level sensor and turbidity sensor are located at the water inlet of the pump body 3, respectively used to monitor water level changes and detect sediment content in real time. The controller uses a fuzzy PID algorithm to dynamically adjust the water pump speed based on the data collected by the water level and turbidity sensors, balancing efficiency and energy consumption. The joint angle encoder group is installed on the boom joint of the excavator boom 2 and the rotating shaft of the water pump mounting bracket 5, collecting the angle values ​​of each joint in real time. The controller automatically calculates the water pump entry angle based on the angle values ​​collected by the joint angle encoder group, reducing manual debugging steps, and controls the pitch adjustment mechanism to perform angle adjustment. Combined with the excavator boom's multi-degree-of-freedom adjustment, this achieves precise control of the water pump entry angle from -30° to 90°, adapting to different water levels and obstacle scenarios.

[0026] Many modifications and other embodiments of the present invention will occur to those skilled in the art with the aid of the teachings presented in the foregoing description and the associated drawings. Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
