Description

Technical Field

[0001] This application relates to the field of drainage equipment technology, and in particular to a drainage robot. Background Technology

[0002] Drainage robot technology plays a crucial role in modern urban drainage and emergency response. With rapid urbanization, urban flooding caused by extreme weather is becoming increasingly severe, and traditional drainage equipment can no longer meet the demands for rapid and efficient drainage. Therefore, developing automated drainage robots with high-efficiency drainage capabilities has become an important direction for industry development. Such equipment can not only significantly improve drainage efficiency but also reduce the complexity and risks of manual operation, providing more reliable protection for urban drainage systems.

[0003] Currently, common methods for solving urban flooding problems include using portable water pumps and vehicle-mounted drainage systems. Portable water pumps typically require manual transport to the flooded area, which is cumbersome and inefficient. Vehicle-mounted drainage systems integrate the pump into a vehicle, utilizing the vehicle's mobility to improve drainage efficiency. However, most existing vehicle-mounted drainage systems use a single pump design with fixed displacement and head, making it impossible to flexibly adjust to different scenarios. Furthermore, traditional equipment often requires complex procedures to place the pump in the flooded area upon arrival, increasing operational difficulty and extending drainage response time.

[0004] Existing drainage equipment struggles to simultaneously meet the demands of large discharge capacity and high head, especially when dealing with varying water depths and drainage environments. The single-pump design limits the equipment's applicability. Furthermore, traditional equipment requires manual intervention during operation, increasing labor intensity and operational complexity, and hindering rapid deployment and efficient drainage. These problems urgently require solutions through technological innovation. Utility Model Content

[0005] To address the drainage problem in the prior art, this application provides a drainage robot.

[0006] This application provides a drainage robot, which adopts the following technical solution:

[0007] A drainage robot includes a walking base with a retraction mechanism on the base. A first submersible pump is suspended on the upper side of the retraction mechanism, and a second submersible pump is installed at the bottom of the walking base. The retraction mechanism includes a retraction rod rotatably connected to the walking base, with a suspension rod rotatably connected to the end of the retraction rod away from the walking base. The first submersible pump is fixedly installed on the suspension rod. The base also has a first drive mechanism for driving the retraction rod to rotate.

[0008] By adopting the above technical solutions, the drainage robot can flexibly deploy and retract the first submersible pump and adjust the height of the second submersible pump, thus adapting to different drainage scenarios. The walking base provides a stable mobile platform for the equipment, and the design of the deployment and retraction mechanism allows the first submersible pump to be quickly deployed to waterlogged areas or retrieved as needed, improving the ease of operation. Meanwhile, the inclusion of the second submersible pump further enhances the equipment's applicability in complex terrain, ensuring the efficiency and flexibility of drainage operations. The two sets of submersible pumps—one with a large head and the other with a large flow rate and a small head—meet the diverse and complex needs of urban drainage.

[0009] Preferably, the first driving mechanism includes a first driving hydraulic cylinder, the cylinder body of the first driving hydraulic cylinder is rotatably mounted on the traveling base, the traveling base is provided with a driving connecting rod, one end of the driving connecting rod is rotatably mounted on the traveling base, the other end of the driving connecting rod is slidably connected to the side of the take-up and extend rod, and the piston rod of the first driving hydraulic cylinder is rotatably connected to the end of the driving connecting rod near the take-up and extend rod.

[0010] By adopting the above technical solution, the first drive hydraulic cylinder can drive the drive linkage to move through the extension and retraction of the piston rod, thereby causing the drive linkage to push the retraction rod to rotate, thus realizing the deployment and retrieval operation of the first submersible pump. This design makes the deployment and retrieval of the first submersible pump more flexible and efficient, reduces manual intervention, and improves the automation and adaptability of the drainage robot. In addition, the hydraulic drive provides the system with higher stability and reliability, enabling it to maintain good working performance in complex environments.

[0011] Preferably, a push rod is also fixedly provided at one end of the drive link near the retractor rod. One end of the push rod is fixedly connected to the drive link, and the other end of the push rod is rotatably connected to the suspension rod.

[0012] By adopting the above technical solution, the push rod configuration effectively enhances the connection stability between the drive linkage and the suspension rod, ensuring the first submersible pump remains stable during deployment and retrieval. Simultaneously, the connection method between the push rod, drive linkage, and suspension rod allows for more flexible position adjustment of the first submersible pump, enabling it to quickly adapt to different drainage needs in complex terrain, thereby improving the overall operational efficiency and reliability of the drainage robot.

[0013] Preferably, a sliding sleeve is fixedly provided on the walking base, and a sliding rod is vertically slidably provided on the sliding sleeve. One end of the second submersible pump is rotatably provided on the walking base, and the other end of the second submersible pump is fixedly provided on one end of the sliding rod. The walking base is also provided with a second driving mechanism for driving the sliding rod to slide.

[0014] By adopting the above technical solution, the cooperative design of the sliding sleeve and sliding rod allows the main body of the second submersible pump to flexibly adjust its position, thereby adapting to water accumulation environments of different depths. Combined with the driving function of the second drive mechanism, the automation level and ease of operation of the drainage robot are also effectively improved.

[0015] Preferably, the second drive mechanism includes a second drive hydraulic cylinder, which is fixedly mounted on the walking base, and the piston rod of the second drive hydraulic cylinder is fixedly connected to the sliding rod.

[0016] By adopting the above technical solution, the second drive hydraulic cylinder enables the sliding rod to move stably along the sliding sleeve, thereby driving the second submersible pump to adjust its position. This design not only improves the adaptability of the equipment, allowing for flexible deployment of the second submersible pump at different water depths, but also simplifies the operation process, reduces manual intervention, and improves drainage efficiency.

[0017] Preferably, the first submersible pump, the retraction mechanism, and the first drive mechanism are all symmetrically arranged in two sets.

[0018] By adopting the above technical solution, the first submersible pump, the deployment and retraction mechanism, and the first drive mechanism of the drainage robot are all symmetrically arranged in two sets, which can significantly improve drainage efficiency and stability. The two sets of first submersible pumps arranged symmetrically can perform drainage operations simultaneously in different directions or positions, adapting to more complex water accumulation environments and reducing the off-center load problem that may occur when a single pump is working. In addition, the symmetrical design of the deployment and retraction mechanism and the first drive mechanism ensures that the movements of the two sides are coordinated and consistent, improving the reliability of equipment operation and further enhancing the adaptability and operational flexibility of the drainage robot.

[0019] Preferably, the second submersible pump, the sliding sleeve, the sliding rod, and the second drive mechanism are all symmetrically arranged in two sets.

[0020] By adopting the above technical solutions, the drainage robot can achieve more stable and efficient drainage operations. The symmetrically arranged two sets of second submersible pumps provide balanced drainage capacity under different working conditions, preventing equipment tilting or damage due to uneven load on one side. Simultaneously, the symmetrical design of the sliding sleeve, sliding rod, and second drive mechanism significantly improves the stability and reliability of the overall structure, ensuring that the equipment maintains good operational performance and drainage efficiency even in complex terrain or high water levels. Furthermore, this design facilitates equipment maintenance and repair, reduces operational difficulty, and further enhances the equipment's practicality and adaptability.

[0021] Preferably, the walking base includes a chassis and tracks, and the retraction mechanism and the second submersible pump are both mounted on the chassis.

[0022] By adopting the above technical solutions, the drainage robot has the ability to adapt to complex terrain. The combination of chassis and tracks enables the walking base to move stably on uneven ground, improving the overall mobility of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By cooperating with the retraction mechanism on the walking base and the first submersible pump, the first submersible pump can be quickly deployed to the waterlogged area, significantly reducing drainage response time and improving the equipment's emergency response capability;

[0025] 2. The second submersible pump, which is set up at the bottom, can be flexibly adjusted according to the actual water depth to achieve a balance between large discharge capacity and high head, meeting the needs of different drainage scenarios. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0031] This application discloses a drainage robot.

[0032] Reference Figure 1 and Figure 2A drainage robot includes a walking base 1, a retraction mechanism 2 on the walking base 1, a first submersible pump 3 hanging on the retraction mechanism 2, and a second submersible pump 4 at the bottom of the walking base 1. The retraction mechanism 2 includes a retraction rod 201 rotatably connected to the walking base 1, and a suspension rod 202 rotatably connected to the end of the retraction rod 201 away from the walking base 1. The first submersible pump 3 is fixedly mounted on the suspension rod 202. The base is also provided with a first drive mechanism 5 for driving the retraction rod 201 to rotate, thereby improving drainage efficiency and flexibility.

[0033] Reference Figure 1 and Figure 2 One end of the retractable rod 201 is rotatably connected to the walking base 1 via a rotating shaft, and the suspension rod 202 is rotatably connected to the other end of the retractable rod 201 via another rotating shaft. The walking base 1 is also provided with a drive link 6, one end of the drive link 6 is rotatably mounted on the walking base 1, and the other end of the drive link 6 is slidably connected to the retractable rod 201 and slides along the retractable rod 201.

[0034] Reference Figure 1 and Figure 2 The first drive mechanism 5 includes a first drive hydraulic cylinder 501. The cylinder body of the first drive hydraulic cylinder 501 is rotatably mounted on the walking base 1 via a hinge, and the piston rod of the first drive hydraulic cylinder 501 is rotatably connected to one end of the drive connecting rod 6 near the retracting rod 201.

[0035] Reference Figure 1 and Figure 2 A push rod 7 is fixedly installed at one end of the drive linkage 6 near the retracting rod 201. One end of the push rod 7 is fixedly connected to the drive linkage 6, and the other end is rotatably connected to the suspension rod 202 via a pin. When the first drive hydraulic cylinder 501 retracts, the end of the drive linkage 6 near the traveling base 1 rotates, and the other end slides away from the traveling base 1 along the retracting rod 201. At this time, the retracting rod 201 rotates and the push rod 7 moves, causing the push rod 7 to push the suspension rod 202 to rotate. The angle between the suspension rod 202 and the retracting rod 201 gradually increases, and the first submersible pump 3 gradually lowers. The first drive hydraulic cylinder 501, the drive linkage 6, and the traveling base 1 form a triangular structure. When the first submersible pump 3 needs to be retracted, the first drive hydraulic cylinder 501 extends. Since the length of the drive linkage 6 is fixed, the drive linkage 6 rotates upward, causing the retracting rod 201 to rotate upward, and the first submersible pump 3 gradually retracts.

[0036] Reference Figure 1 and Figure 3A sliding sleeve 8 is fixedly mounted on the walking base 1, and a sliding rod 9 is vertically slidably mounted on the sliding sleeve 8. The sliding rod 9 is vertically slidably mounted inside the sliding sleeve 8. One end of the second submersible pump 4 is rotatably connected to the walking base 1, and the other end is fixedly connected to the sliding rod 9. The second drive mechanism 10 includes a second drive hydraulic cylinder 1001, which is fixedly mounted on the walking base 1. The piston rod of the second drive hydraulic cylinder 1001 is fixedly connected to the sliding rod 9. Through the extension and retraction of the second drive hydraulic cylinder 1001, the sliding rod 9 can move up and down, thereby driving the second submersible pump 4 to rotate and realize the up and down swing of the second submersible pump 4.

[0037] Reference Figure 1 and Figure 3 The first submersible pump 3, the retraction mechanism 2, and the first drive mechanism 5 are all symmetrically arranged in two sets, as are the second submersible pump 4, the sliding sleeve 8, the sliding rod 9, and the second drive mechanism 10. This symmetrical design improves the stability and load-bearing capacity of the equipment, preventing excessive force on one side from causing tilting or damage. The two symmetrically arranged sets of first submersible pumps 3 can be controlled independently by the retraction mechanism 2, achieving multi-point drainage; the two symmetrically arranged sets of second submersible pumps 4 can be controlled independently by the lifting mechanism, achieving multi-point adjustment. This design not only improves drainage efficiency but also enhances the reliability and safety of the equipment.

[0038] Reference Figure 1 and Figure 3 The walking base 1 includes a chassis 101 and tracks 102, and the retraction mechanism 2 and the second submersible pump 4 are both mounted on the chassis 101.

[0039] The implementation principle of this application embodiment is as follows: A dual-group submersible pump structure—one group with a large head and the other with a large flow rate and a small head—allows for flexible adjustment of the drainage robot's discharge capacity and head. The first submersible pump 1 achieves long-distance deployment via the deployment and retraction mechanism 2, suitable for drainage in open water areas; the second submersible pump 4 oscillates up and down to achieve localized drainage, suitable for drainage in narrow spaces or deep water areas. This design not only improves drainage efficiency but also enhances the equipment's adaptability. Simultaneously, the use of a hydraulic drive system enables precise control and rapid response, reducing operational difficulty and improving work efficiency.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
