Description

Technical Field

[0001] This utility model relates to the field of drainage machinery technology, and in particular to a flood drainage robot. Background Technology

[0002] Following urban flooding or regional flooding, various drainage machines are needed to carry out drainage operations in the affected areas. Currently, commonly used drainage robots are typically transported to the site by vehicles. Once operational, the direction of the water outlet from the drainage pipes needs frequent adjustments to alleviate drainage pressure in the flood-receiving area. This requires controlling the robot's overall movement, relying on its tracks or wheels to adjust its position and orientation. However, in drainage scenarios with complex road conditions or slippery surfaces, frequent movement of the drainage robot not only increases the risk of overturning or getting stuck but also wastes valuable drainage and rescue time, resulting in low drainage efficiency.

[0003] In view of this, the present invention proposes a drainage robot to solve or at least alleviate the above-mentioned problems. Utility Model Content

[0020] In one embodiment, the drainage assembly further includes a winding motor mounted on the winding frame, and the output shaft of the winding motor is connected to the reel to drive the reel to rotate.

[0040] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] 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.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] When cities experience severe weather leading to flooding (such as in urban tunnels and underground pedestrian crossings), or when regional flooding inundates low-lying areas, the water depth can exceed 0.5 meters, creating stagnant zones. In such disaster scenarios, specialized drainage machinery must be deployed for emergency operations. Most mainstream drainage robots currently employ a modular design. After being transported to the disaster site by flatbed trucks, they require operation by technicians. Their working principle involves using an onboard water pump to draw water into drainage pipes, which then transport it to designated drainage points. Because the drainage capacity of a single drainage point is limited, when the drainage capacity of a point reaches its limit, or when it is necessary to avoid important buildings, the drainage direction must be adjusted promptly. In this case, operators need to control the overall movement of the drainage robot via a remote control terminal, using its tracks or wheels to change the position and orientation of the equipment, aligning the drainage pipe outlet with another drainage point.

[0045] In real-world disaster relief scenarios, drainage robots often face challenges from complex terrain. Unpaved roads may contain areas prone to sinking, and newly constructed construction sites are littered with construction debris such as gravel and concrete blocks, all of which affect the stability of the equipment's movement. Especially after continuous rainfall or flooding, the coefficient of friction on the ground decreases significantly, making the wheels prone to slipping when turning on wet surfaces, and even potentially causing rollovers due to a shift in the center of gravity. Furthermore, frequently adjusting the position and orientation of the drainage robot consumes a large amount of energy, reducing its range. This situation also results in a significant amount of time being wasted on positioning rather than pumping water, especially when precise alignment (such as at sewer inlets) or multi-directional drainage is required. The lack of directional adjustment capability in these situations means that, in the race against time during disaster relief, this time loss directly reduces overall drainage efficiency and severely impacts the recovery progress of the affected area.

[0046] Therefore, this utility model proposes a drainage robot to solve the above problems.

[0047] Please see Figures 1 to 6 In one embodiment of this utility model, the drainage robot 1000 includes a housing 1, a pumping assembly 2, a water pipe 3, a rotary joint 4, an adjustment structure 5, and a drainage assembly 6. The pumping assembly 2 includes a water pump 21 and a pumping pipe 22 connected to the water pump 21, with the water pump 21 installed in the housing 1. The water pipe 3 is installed inside the housing 1. The rotary joint 4 includes a housing 41 and a rotating pipe 42, with the housing 41 installed in the housing 1 and the rotating pipe 42 rotatably installed in the housing 41. The two ends of the water pipe 3 are connected to the water pump 21 and the housing 41, respectively. The adjustment structure 5 includes a first gear 51, a rotating bracket 52, a first connecting rod 53, a second connecting rod 54, and a ball joint assembly 55. The ball joint assembly 55 includes mutually cooperating components... Ball seat 551 and universal ball joint 552, the two ends of the first connecting rod 53 are respectively connected to the rotating tube 42 and the ball seat 551, one end of the second connecting rod 54 is connected to the universal ball joint 552, and the first gear 51 is fixedly sleeved on the first connecting rod 53; the rotating bracket 52 includes a support 521, a rotating shaft 522, a support arm 523 and a support plate 524, the support 521 is fixedly installed on the side of the first gear 51 away from the housing 1, the support arm 523 is hinged to the support 521 through the rotating shaft 522, the support plate 524 is installed on the support arm 523, and the second connecting rod 54 passes through the support plate 524; the drainage component 6 is installed on the support plate 524, and the drainage component 6 includes a drainage pipe 62, which is connected to the second connecting rod 54.

[0048] In use, the drainage robot 1000 first moves to the area to be drained (such as a flooded road surface), places the pumping pipe 22 in the area, starts the water pump 21, and the water flows through the pumping pipe 22, the water pump 21 and the water pipe 3 into the rotary joint 4. After passing through the rotary joint 4, the water flows through the first connecting rod 53, the ball seat 551, the universal ball head 552 and the second connecting rod 54, and is discharged through the drain pipe 62. The shape of the end of the second connecting rod 54 away from the ball seat 551 can be designed according to the connection requirements of the drain pipe 62. In this embodiment, the second connecting rod 54 and the drain pipe 62 are connected by a flange. When the drainage direction needs to be adjusted, rotating the first gear 51 drives the rotating pipe 42 and the rotating bracket 52 to rotate horizontally, thereby causing the rotating bracket 52 to drive the drain pipe 62 to rotate horizontally. The first gear 51 can mesh with an external drive gear to drive its rotation, or it can be manually driven to rotate using a hand-held wrench. By adjusting the angle between the support arm 523 and the support 521, the drain pipe 62 can be rotated in the vertical plane. This allows for adjustment of the horizontal and pitch angles of the drain pipe 62. The support plate 524 and the support arm 523 form a U-shaped structure, which is symmetrically arranged. The two support arms 523 are hinged to the two supports 521 via two rotating shafts 522. This arrangement makes the rotation of the second connecting rod 54 more stable, preventing excessive swaying during rotation.

[0049] Through the technical solution of this embodiment, since the ball head assembly 55 and the rotary joint 4 can rotate flexibly, when it is necessary to adjust the drainage direction, the top end of the second connecting rod 54 can be rotated horizontally by rotating the first gear 51, and the top end of the second connecting rod 54 can be rotated in the vertical plane by rotating the support arm 523. Thus, the drainage direction can be flexibly adjusted without moving the drainage robot 1000, avoiding the risks of overturning and stagnation caused by frequently adjusting the position of the drainage robot 1000. At the same time, it saves the time of adjusting the drainage robot 1000, allowing the water pump 21 to operate continuously, thereby improving the efficiency of drainage operations.

[0050] Further, see Figure 3In one embodiment of this utility model, the adjustment structure 5 further includes a second gear 56 and a first drive motor 57. The second gear 56 meshes with the first gear 51, and the first drive motor 57 is mounted on the housing 1. The second gear 56 is connected to the output shaft of the first drive motor 57. The first drive motor 57 can be either a stepper motor or a servo motor. This configuration allows the first drive motor 57 to drive the second gear 56 to rotate, thereby causing the first gear 51 to rotate and adjusting the drainage direction of the drain pipe 62. Thus, there is no need for an external gear to mesh with the first gear 51, or for tools such as a wrench to drive the first gear 51, thereby improving the automation level of the drain pipe 62 rotation process and reducing the time consumed by the drain pipe 62 rotation.

[0051] For further information, please continue reading. Figure 3 In one embodiment of this utility model, the adjustment structure 5 further includes a second drive motor 58, which is mounted on the support 521. A rotating shaft 522 is connected to the output shaft of the second drive motor 58, and the rotating shaft 522 rotates synchronously with the support arm 523. The second drive motor 58 includes either a stepper motor or a servo motor. The main body of the second drive motor 58 is fixedly mounted on the support 521, and its output shaft rotates synchronously with the rotating shaft 522. The rotating shaft 522 can drive the support arm 523 to rotate synchronously. Thus, only the rotation angle of the output shaft of the second drive motor 58 needs to be controlled to control the pitch angle of the drain pipe 62, thereby further improving the automation level of the drainage direction adjustment process of the drain pipe 62.

[0052] In one embodiment of this utility model, please refer to Figure 4 and Figure 5 The ball seat 551 has a ball groove 5511, and the universal ball head 552 has a through hole 5521, which is accommodated in the ball groove 5511. The ball seat 551 has a limiting flange 5512, which extends toward the universal ball head 552. The universal ball head 552 has a limiting stop 5522, which is accommodated in the ball groove 5511. The through hole 5521 is located inside the limiting stop 5522. In this embodiment, the ball seat 551 has a notch, and the limiting flange 5512 is located inside the notch. The depth of the notch can be designed according to the adjustment range of the pitch angle of the drain pipe 62. The side of the limiting flange 5512 facing the universal ball head 552 abuts against the surface of the universal ball head 552. During drainage operations, accumulated water enters the ball groove 5511 through the first connecting rod 53, then enters the interior of the universal ball head 552 through the through hole 5521, and finally flows into the second connecting rod 54. By setting the cooperation between the limiting stop 5522 and the limiting fold 5512, excessive rotation of the universal ball head 552 can be avoided, thereby preventing the through hole 5521 from disengaging from the ball groove 5511.

[0053] In one embodiment of this utility model, please refer to Figure 5 The ball joint assembly 55 also includes a sealing ring 553, which is fitted onto the side of the limiting flange 5512 facing the first connecting rod 53. The opposite sides of the sealing ring 553 are respectively fitted to the inner wall of the ball groove 5511 and the outer surface of the universal ball joint 552. By setting the sealing ring 553, the ball groove 5511 is kept in a sealed state, preventing water accumulated in the ball groove 5511 from flowing out along the gap between the ball groove 5511 and the universal ball joint 552.

[0054] In one embodiment of this utility model, please refer to Figure 4 and Figure 5 The ball joint assembly 55 also includes a limiting rod 554. A limiting groove 5514 is formed in the ball seat 551, extending circumferentially along the ball seat 551. One end of the limiting rod 554 is mounted on the outer side of the universal ball joint 552, and the limiting rod 554 passes through the limiting groove 5514. The extending direction of the limiting groove 5514 is parallel to the side of the first gear 51 away from the housing 1. This arrangement restricts the horizontal rotation of the universal ball joint 552 relative to the ball seat 551, preventing the universal ball joint 552 from causing the second connecting rod 54 to rotate excessively. This keeps the angle between the second connecting rod 54 and the drain pipe 62 within a preset range, preventing water from flowing sluggishly due to an excessive angle. Furthermore, the cooperation of the limiting rod 554 and the limiting groove 5514 provides a fulcrum for the rotation of the second connecting rod 54 in the vertical plane, facilitating accurate adjustment of the pitch angle of the second connecting rod 54.

[0055] Please see Figure 6 In one embodiment of this utility model, the drainage assembly 6 further includes a reel 61 and a winding frame 63. The winding frame 63 is installed on the side of the support plate 524 away from the first gear 51. The drainage pipe 62 is wound around the reel 61, and the reel 61 is hinged to the winding frame 63. The drainage pipe 62 is connected to the end of the second connecting rod 54 away from the universal ball joint 552. The drainage pipe 62 is a flexible hose. By winding it around the reel 61, it can be released or retracted by the reel 61, thereby flexibly adjusting the drainage distance.

[0056] For further information, please refer to [link / reference]. Figure 6 In one embodiment of this utility model, the drainage assembly 6 further includes a winding motor 64, which is mounted on a winding frame 63. The output shaft of the winding motor 64 is connected to a reel 61 to drive the reel 61 to rotate. The winding motor 64 includes either a stepper motor or a servo motor. The main body of the winding motor 64 is fixedly mounted on the winding frame 63, and its output shaft rotates coaxially with the reel 61 to achieve automatic winding and unwinding of the drainage pipe 62, thereby improving the automation level of the drainage distance adjustment process.

[0057] Please see Figure 1 In one embodiment of this utility model, the drainage robot 1000 further includes a walking component 7, which is installed at the bottom of the housing 1 to support the movement of the housing 1. The walking component 7 includes either a track or a rubber tire. In order to enable the drainage robot 1000 to adapt to various terrains and enhance its stability during movement and drainage, a track is used as the walking component 7 in this embodiment.

[0058] Please see Figure 2 In one embodiment of this utility model, the pumping pipe 22 includes a main pipe 221 and at least two branch pipes 222. The main pipe 221 is connected to the water pump 21, and the at least two branch pipes 222 are connected to the end of the main pipe 221 away from the water pump 21. With this arrangement, one water pump 21 can cover multiple drainage points, saving the number of drainage robots 1000, the space occupied, and the energy consumption.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
