Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection, specifically a robot for detecting full water levels in drainage pipelines. Background Technology

[0002] Drainage pipes are piping systems used to collect and discharge liquids such as sewage and rainwater, and are crucial in building and municipal engineering. They are typically made of materials such as plastics (e.g., PVC, PE), metals (e.g., cast iron), or concrete, and are characterized by corrosion resistance, pressure resistance, and durability. Drainage pipes can be classified by use into sewage pipes, rainwater pipes, and combined sewer pipes, and by connection method into socket, adhesive, or flange connections. A well-designed drainage pipe system can effectively prevent water accumulation, blockages, and pollution, ensuring the hygiene and safety of living and production environments. Regular maintenance and inspection of drainage pipes can extend their service life and prevent problems such as leaks or ruptures.

[0003] Currently, the mainstream methods for detecting drain pipes mostly involve inserting a probe into the pipe and using a built-in camera to observe the internal condition of the pipe. However, these probes are usually made of flexible materials and have weak bending resistance. When the drain pipe is full of water, the buoyancy and flow of the water will exacerbate the shaking of the probe. As the insertion depth increases, the probe is more likely to bend, deviate, or even get stuck, which seriously affects the imaging quality and detection accuracy, and it is impossible to clear blockages.

[0004] Therefore, this utility model provides a robot for detecting full water in drainage pipes to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A robot for detecting full water levels in drainage pipes includes a pipe body with a detection tube inside. A protective tube is fixedly connected to one side of the detection tube, and a submersible camera is fixedly connected to one side of the protective tube. A cleaning assembly is provided on one side of the detection tube, comprising a protective seat slidably connected inside the protective tube, a fixing sleeve installed inside the protective seat, a square rod slidably connected inside the fixing sleeve, and an insert rod installed on one side of the square rod. A drive assembly is provided on one side of the detection tube, comprising a support tube installed on one side of the detection tube, a rotating shaft movably connected inside the support tube, and drive blades installed on the surface of the rotating shaft.

[0007] Furthermore, in this utility model, the drive assembly also includes a dual-axis motor installed inside the protective tube, a first gear installed at one output end of the dual-axis motor, a second gear installed at the other end of the rotating shaft, and one end of the square rod is fixedly connected to the other output end of the dual-axis motor.

[0008] Furthermore, in this invention, one side of the first gear meshes with the second gear, and the surface of the rotating shaft is movably connected to the inner wall of the detection tube via a bearing.

[0009] Furthermore, in this invention, the cleaning assembly also includes a circular guide rail movably connected inside the protective base, an electric push rod installed inside the protective tube, and a cutting blade installed on one side of the protective base.

[0010] Furthermore, in this utility model, the output end of the electric push rod is fixedly connected to the circular guide rail, and a storage groove is provided on one side of the protective seat.

[0011] Furthermore, in this utility model, an electric hoist is provided at the top of the pipe body, and a traction rope is installed inside the electric hoist. The other end of the traction rope is fixedly connected to the detection pipe.

[0012] Furthermore, in this invention, a support frame is fixedly connected to the surface of the detection tube, and a support wheel is movably connected inside the support frame.

[0013] Beneficial effects: This utility model has the following beneficial effects:

[0014] 1. This utility model effectively solves the problem of traditional flexible detection tubes being prone to bending and deformation in full-water pipelines through the coordinated design of rigid detection tubes and support frames. The detection tube is made of high-strength material and, together with the support wheels, makes multiple points of contact with the inner wall of the tube, ensuring that the equipment maintains a vertical and stable posture in a full-water environment. The dual-axis motor in the drive assembly drives the fan blades to rotate through gear transmission, generating a stable propulsion force, enabling the detection tube to overcome water flow resistance and penetrate deep into the pipeline. The imaging quality of the submersible camera is not affected by water flow, providing a reliable guarantee for the comprehensive inspection of full-water pipelines.

[0015] 2. This utility model integrates the cleaning component into the detection system. Through the cooperation of the retractable cutting blade and the rotating rod, the instant cleaning function is realized during the detection process. When the submersible camera detects a blockage in the pipe, the electric push rod can quickly unfold the protective seat, allowing the cutting blade to contact the blockage. At the same time, the dual-axis motor drives the rod to rotate and wrap around the debris. This integrated design avoids the defect of having to interrupt the operation when encountering a blockage in traditional detection, thus improving detection efficiency. Attached Figure Description

[0022] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figure 1-2 As shown, this is the first embodiment of the present invention. This embodiment provides a robot for detecting full water in drainage pipes, including a pipe body 1, a detection pipe 2 disposed inside the pipe body 1, a protective pipe 3 fixedly connected to one side of the detection pipe 2, and a submersible camera 4 fixedly connected to one side of the protective pipe 3; a cleaning component is disposed on one side of the detection pipe 2, the cleaning component including a protective seat 5 slidably connected to the inside of the protective pipe 3, a fixing sleeve 6 installed inside the protective seat 5, a square rod 7 slidably connected to the inside of the fixing sleeve 6, and an insert rod 8 installed on one side of the square rod 7; a driving component is disposed on one side of the detection pipe 2, the driving component including a support pipe 9 installed on one side of the detection pipe 2, a rotating shaft 10 movably connected to the inside of the support pipe 9, and a driving fan blade 11 installed on the surface of the rotating shaft 10.

[0025] like Figure 1As shown, the submersible camera 4 uses a wide-angle high-definition lens and a high-sensitivity sensor to capture clear images even in dim environments inside the pipe 1. The built-in LED fill light can automatically adjust according to the ambient brightness to ensure uniform brightness of the captured image. The submersible camera 4 transmits the captured image to the ground control terminal in real time via a waterproof cable. It adopts anti-interference signal processing technology to ensure stable image quality during long-distance transmission. The waterproof cable is released and retracted synchronously with the traction rope 20, which is a mature existing technology application. The protective seat 5 adopts a sliding connection design, which can be flexibly adjusted as needed. The cooperation structure between the fixing sleeve 6 and the square rod 7 allows the insertion rod 8 to rotate stably. The insertion rod 8 adopts a barbed design, which can effectively wrap around fibrous debris inside the pipe. This combined cleaning structure can not only remove blockages, but also prevent secondary blockages.

[0026] Example 2

[0027] Reference Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] In this embodiment, the drive assembly also includes a dual-axis motor 12 installed inside the protective tube 3, a first gear 13 installed at one output end of the dual-axis motor 12, a second gear 14 installed at the other end of the rotating shaft 10, one end of the square rod 7 being fixedly connected to the other output end of the dual-axis motor 12, one side of the first gear 13 meshing with the second gear 14, and the surface of the rotating shaft 10 being movably connected to the inner wall of the detection tube 2 via a bearing. The cleaning assembly also includes a circular guide rail 15 movably connected inside the protective seat 5, an electric push rod 16 installed inside the protective tube 3, and a cutting blade 17 installed on one side of the protective seat 5.

[0029] like Figure 2 As shown, the support tube 9 provides stable support for the rotating shaft 10, ensuring the smooth operation of the drive fan blade 11. The drive fan blade 11 adopts an inclined blade angle design, which can generate sufficient propulsion to push the detection tube 2 forward in the full water pipe. This active propulsion method overcomes the limitations of traditional detection that relies on gravity to dive, so that the detection depth is no longer limited. The dual-axis motor 12 transmits power to the rotating shaft 10 and the square rod 7 simultaneously through the meshing of the first gear 13 and the second gear 14. This design realizes the synchronous operation of cleaning and propulsion functions, which greatly improves the detection efficiency. The bearing support structure ensures that the rotating shaft 10 operates smoothly and reduces the interference of vibration on the underwater camera 4.

[0030] Example 3

[0031] Reference Figure 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] In this embodiment, the output end of the electric push rod 16 is fixedly connected to the circular guide rail 15, a storage slot 18 is provided on one side of the protective seat 5, an electric hoist 19 is provided on the top of the tube body 1, a traction rope 20 is installed inside the electric hoist 19, the other end of the traction rope 20 is fixedly connected to the detection tube 2, a support frame 21 is fixedly connected to the surface of the detection tube 2, and a support wheel 22 is movably connected inside the support frame 21.

[0033] like Figure 3-5 As shown, the circular guide rail 15 allows the protective seat 5 to move in a circular motion. At the same time, the electric push rod 16 can precisely control the position of the protective seat 5. The storage slot 18 is designed to facilitate the storage of the insertion rod 8. When the impurities on the surface of the insertion rod 8 are too heavy, causing the insertion rod 8 to be unable to be pulled upward, the electric push rod 16 can be used to drive the protective seat 5 and the cutting blade 17 to reset. The cutting blade 17 can then be used to cut off the impurities wrapped around the surface of the insertion rod 8. The electric hoist 19 uses the traction rope 20 to control the lifting and lowering of the detection tube 2, which can quickly retrieve the equipment after the detection is completed. The support frame 21 adopts a multi-point support design, and the support wheel 22 contacts the inner wall of the tube body 1 to ensure that the detection tube 2 always remains vertical. This guiding structure effectively prevents the detection tube 2 from deviating during long-distance advancement and ensures that the submersible camera 4 is always aligned with the center line of the pipeline.

[0034] During use, the staff sets up the electric hoist 19 on top of the pipe 1 to be inspected, and at the same time controls the electric hoist 19 to initially release the traction rope 20. Then, the inspection tube 2 is released downward and inserted into the inside of the pipe 1. The support wheel 22 contacts the inner wall of the pipe 1, so that the inspection tube 2 can penetrate vertically into the water. Then, the underwater camera 4 is activated to take pictures of the inside of the pipe 1 and upload the video in real time, so that the staff can observe the inside of the pipe 1 in a timely manner.

[0035] When it is necessary to continue descending to the submersible camera 4, the dual-axis motor 12 can be activated. The dual-axis motor 12, in conjunction with the first gear 13, drives the second gear 14 to rotate. The second gear 14, in conjunction with the rotating shaft 10, drives the drive fan blade 11 to rotate. Using the reaction force of the water flow pushed by the drive fan blade 11, the detection tube 2 continues to descend, enabling it to capture and detect the situation at different depths inside the tube 1. When the camera detects impurities clogging the inside of the tube 1, the electric push rod 16 can be activated. The electric push rod 16 drives the protective seat 5 to retract into the protective tube 3, exposing the insertion rod 8. There are three insertion rods 8, all of which are inverted. Under the action of the drive fan blade 11, a pushing force is applied, thus inserting them into the impurities. At the same time, driven by the dual-axis motor 12, the square rod 7 and the insertion rod 8 can be rotated. The rotation of the insertion rod 8 is used to wrap and fix the impurities. Afterwards, the electric hoist 19 can be activated to wind up the traction rope 20. The insertion rod 8 is used to pull the impurities upward, clearing the impurities clogging the inside of the tube 1, thus achieving a cleaning effect.
