Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and in particular to a telescopic rod type slot dredging robot. Background Technology

[0002] Dredging robots are automated devices used to clean up silt, debris, or blockages. They are mainly used in urban drainage networks, rivers, reservoirs, industrial pipelines, and sewage treatment plants. Dredging robots generally consist of a mobile platform with a wheeled or tracked chassis. The mobile platform is equipped with dredging functional components, and a collection and conveying system is located at one end of the mobile platform.

[0003] A search revealed that utility model patent CN215211233U discloses an underwater ecological dredging robot, comprising a main body with tracks at the lower end and a pump body inside. A drain pipe is connected to the upper end of the pump body. A first mounting block is located at the end of the main body, and a connecting rod is mounted on the first mounting block. One end of the connecting rod is connected to the first mounting block, and the other end is connected to a second mounting block. A protective shell is located at the lower end of the second mounting block. A through hole is located at one end of the protective shell, and a fixing block is located at the other end. This utility model can clean silt adhering to the bottom wall of sewer pipes, improving the dredging effect and efficiency.

[0004] In the structure disclosed in the above-mentioned utility model, spiral blades are used to clean up debris. However, when applied to cleaning bridge expansion joints, which are usually narrow or widened gaps ranging from a few centimeters to tens of centimeters in width, the spiral blades are difficult to cover the accumulated mud and debris in the bridge expansion joints when the dredging robot is cleaning them. Furthermore, the use of spiral blades can easily cause collisions that damage the sealing structures such as bridge rubber strips and waterstops, thus damaging the bridge expansion joints. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a telescopic rod-type slit dredging robot.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic rod type slit dredging robot, comprising a robot body, an installation chamber at one end of the robot body, a fixed rod rotatably connected to the inner wall of the installation chamber, a limiting groove on the inner wall of the fixed rod, a movable rod slidably connected to the inner wall of the limiting groove, and a cleaning shovel fixed at one end of the movable rod.

[0007] Preferably, a bearing seat is fixed in the middle of the inner wall of the installation chamber, a drive motor is fixed in the top of the inner wall of the installation chamber, and a starter motor is fixed in the bottom of the inner wall of the installation chamber.

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Reference Figures 1-5The telescopic rod-type slit cleaning robot includes a robot body 1, which comprises a mobile platform formed by a tracked chassis. The mobile platform is equipped with sludge cleaning components, and a collection and conveying system is located at one end of the mobile platform. An installation chamber 404 is opened at one end of the robot body 1. A fixed rod 2 is rotatably connected to the inner wall of the installation chamber 404. A limiting groove is opened in the inner wall of the fixed rod 2, and a movable rod 201 is slidably connected to the inner wall of the limiting groove. A cleaning shovel 3 is fixed at one end of the movable rod 201. The telescopic connection between the fixed rod 2 and the movable rod 201 allows workers to easily reach the bridge expansion joints for cleaning through the cleaning shovel 3. At the same time, the fixed rod 2, which is rotatably connected to the inner wall of the installation chamber 404, changes the direction of the cleaning shovel 3 by rotating, covering bridge expansion joints of different widths and cleaning up the mud, sand, and debris accumulated in the bridge expansion joints. While facilitating cleaning, it also prevents equipment such as spiral blades from colliding with bridge rubber strips, waterstops, and other sealing structures, which could damage the bridge expansion joints.

[0028] A bearing housing 402 is fixed in the middle of the inner wall of the mounting chamber 404. A drive motor 4 is fixed in the top of the inner wall of the mounting chamber 404, and a starter motor 403 is fixed in the bottom of the inner wall of the mounting chamber 404. A collar 401 is fixed to the output end of both the drive motor 4 and the starter motor 403. The output ends of both the drive motor 4 and the starter motor 403 are rotatably connected to the bearing housing 402. A side connecting rod 405 is fixed to the circumference of the collar 401 of the drive motor 4. A diagonal connecting rod 406 is rotatably connected to the inner wall of the side connecting rod 405. One end of the diagonal connecting rod 406 is rotatably connected to an end post 407. The bottom of column 407 is fixed to the top of moving rod 201, and the end of fixed rod 2 away from cleaning shovel 3 is fixed to the circumference of collar 401 of starter motor 403. The rotation of drive motor 4 drives collar 401 to rotate side connecting rod 405, pushes inclined connecting rod 406 and end column 407 to make moving rod 201 move forward or backward, changing the extension of cleaning shovel 3. At the same time, the rotation of starter motor 403 causes collar 401 and fixed rod 2 to rotate, changing the orientation of cleaning shovel 3. The length and orientation of cleaning shovel 3 can be changed using a simple structure, which is convenient for operators to operate and maintain.

[0029] A protective cover 5 is fixed to one end of the installation chamber 404. The surface of the protective cover 5 has multiple reserved slots 501. The inner wall of the lower reserved slot 501 is in contact with the surface of the fixed rod 2. The protective cover 5 protects the internal mechanism of the installation chamber 404 and prevents foreign objects from entering the installation chamber 404. At the same time, the reserved slot 501 supports the bottom of the fixed rod 2 and prevents the fixed rod 2 from bending when subjected to force.

[0030] A bottom ring 6 is fixed to one end of the moving rod 201 near the cleaning shovel 3. The inner wall of the bottom ring 6 has an inner ring groove 601. A locking post 602 is fixed to one end of the cleaning shovel 3 near the moving rod 201. A locking end ring 603 is fixed to one end of the locking post 602. The bottom ring 6 and the locking post 602 are fixed together by a buckle, which makes it easy for the staff to change different cleaning heads, thus making it more suitable for different usage scenarios.

[0031] The edge of the end ring 603 away from the cleaning shovel 3 is set as the ring end arc surface 7, and the edge of the bottom ring 6 near the locking post 602 is set as the bottom ring arc surface 701. Through the design of the ring end arc surface 7 and the bottom ring arc surface 701, the two are more likely to deform and nest when in contact, preventing damage caused by hard squeezing and improving their service life.

[0032] The inner wall of the embedded annular groove 601 is set as an annular groove slope 8 near the edge of the cleaning shovel 3. When the clamping ring 603 leaves, the force path is reduced through the annular groove slope 8, which reduces the damage caused by the hard squeezing of the two and makes it easier for the staff to pull out the clamping post 602.

[0033] A deformation groove 9 is provided at one end of the clamping post 602 near the moving rod 201. The deformation groove 9 is not less than three millimeters wide. The deformation groove 9 provides deformation space to the clamping post 602, which facilitates the installation of the cleaning shovel 3 by the staff.

[0034] A rubber pad is glued to the end of the moving rod 201 away from the cleaning shovel 3. The rubber pad provides buffering and isolation between the cleaning shovel 3 and the moving rod 201 to prevent damage from collision and increase the service life of both.

[0035] The working principle of this utility model is as follows: When workers need to clean the bridge expansion joint, a suitable cleaning shovel 3 is installed on the moving rod 201 according to the usage. When the locking post 602 is inserted into the embedded ring 6, the arc surface 7 of the ring end and the arc surface 701 of the bottom ring make it easier for them to deform by relying on the deformation groove 9 when they come into contact, so that the locking end ring 603 is locked into the embedded ring groove 601. When cleaning begins, the workers control the rotation of the drive motor 4 to drive the collar 401 to rotate the side connecting rod 405, push the inclined connecting rod 406 and the end post 407 to make the moving rod 201 move forward or backward, changing the extension of the cleaning shovel 3. At the same time, the rotation of the motor 403 is started to make the collar 401 and the fixed rod 2 rotate, changing the orientation of the cleaning shovel 3, thereby operating the cleaning shovel 3 to go deep into the inner wall of the bridge expansion joint to shovel off the mud, sand and debris, so that the debris is shoveled away and is difficult to aggregate, and is washed away with the water flow, or is easy for workers to use collection equipment to pull it out.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
