Description

Technical Field

[0001] This utility model relates to the field of sewage pipe network detection, and in particular to an adjustable-angle sewage pipe network detection device. Background Technology

[0002] Wastewater pipe network inspection is a key measure to ensure the safe operation of the city. First, aging, cracks, or sediment accumulation inside the pipe network can directly cause ground subsidence, sewage backflow, and environmental pollution. It is necessary to proactively discover hidden dangers through internal inspection. Second, hidden defects such as corrosion of the inner wall of the pipe and misalignment of the joints cannot be identified from the outside. Only by going deep inside can the location of the disease be accurately located and the degree of damage be quantified, providing a basis for repair plans.

[0003] There are several methods for inspecting the inside of sewage pipes. One method is to use CCTV cameras to record images of the inner wall of the pipe. Another method is to use sonar scanning to detect the thickness of sediment in full-water pipe sections. A third method is to use lasers or 3D modeling to scan for pipe wall deformation or cracks. A fourth method is to use intelligent detectors equipped with adjustable gimbals and sensors to conduct multi-angle inspections of bends and branches, proactively identifying potential problems through internal "check-ups" and avoiding costly emergency repairs.

[0004] In existing technologies, detectors need to penetrate deep into sewage pipes for detection, but detectors can generally only move horizontally back and forth, resulting in blind spots. Due to angle limitations, bends and misaligned joints cannot be fully imaged, and side wall cracks cause distortion in length or width measurements due to non-perpendicular observation, reducing detection accuracy. To address these issues, an adjustable-angle sewage pipe network detection device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable-angle sewage pipe network detection device, which aims to improve the problem that the existing adjustable-angle sewage pipe network detection devices cannot be adjusted to multiple angles, resulting in reduced detection accuracy.

An adjustment plate is provided on the outside of the slide. A sliding groove is provided on the side wall of the adjustment plate.

[0021] This utility model has the following beneficial effects:

[0022] 1.

[0030] 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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of an adjustable-angle sewage pipe network detection device, comprising a fixed base 1, a motor 2 fixedly connected to the outer wall of the fixed base 1, a slot 3 formed on the side wall of the motor 2, a rotating shaft 4 fixedly connected to the output end of the motor 2, the end of the rotating shaft 4 being rotatably connected to the inner wall of the slot 3, a transmission belt 5 being driven by a transmission wheel to the outer wall of the rotating shaft 4, and a screw 6 being driven by the transmission wheel to the transmission belt 5, the screw 6 penetrating the fixed base 1 and rotatably connected to the inner wall of the fixed base 1, and a limit rod 7 fixedly connected to the outer wall of the fixed base 1, which, in conjunction with the limit rod 7, controls the movement of the base. The limit rod 7 is used to limit the movement of the movable seat 8 along the axial direction of the sewage pipe, ensuring that the detection device can penetrate into different positions inside the pipe network for detection. The movable seat 8 is slidably connected to the outer wall of the limit rod 7. The inner wall of the movable seat 8 is threadedly connected to the outer wall of the screw rod 6. The movable seat 8 is circular and can adapt to the shape of the sewage pipe. The side wall of the movable seat 8 is fixedly connected to the motor 9. The output end of the motor 9 is fixedly connected to the gear 10 through the rotating rod. The center of the movable seat 8 is rotatably connected to the support shaft 12. The outer wall of the support shaft 12 is fixedly connected to the gear 11. The gear 10 and the gear 11 mesh with each other.

[0032] Reference Figures 2-4 A turntable 13 is fixedly connected to the end of the support shaft 12. A mounting groove 14 is provided on the side wall of the turntable 13. An electric push rod 15 is fixedly connected to the inner wall of the mounting groove 14. Two sets of electric push rods 15 are provided, and the two sets of electric push rods 15 are symmetrically arranged with respect to the center point of the turntable 13. A mounting plate 16 is fixedly connected to the output end of the electric push rod 15. A slide block 17 is hinged to the side wall of the mounting plate 16. The number of slide blocks 17 and mounting plates 16 is equal to the number of electric push rods 15. The two sets of electric push rods 15 can switch on and off by sliding in the slide groove 19 through the slide block 17, which can change the pitch angle of the adjustment plate 18. An adjustment plate 18 is provided on the outside of the slide block 17. A slide groove 19 is provided on the side wall of the adjustment plate 18. The inner wall of the slide groove 19 is slidably connected to the outer wall of the slide block 17 away from the mounting plate 16. A detector 20 is fixedly connected to the outer wall of the adjustment plate 18 away from the slide groove 19.

[0033] Reference Figure 3A limiting plate 21 is fixedly connected to the outer wall of the fixed seat 1. A screw rod 23 is threadedly connected to the inner wall of the limiting plate 21. A knob 22 is fixedly connected to one end of the screw rod 23, and a clamping plate 25 is rotatably connected to the other end of the screw rod 23. The clamping plate 25 is arc-shaped. A sliding rod 24 is fixedly connected to the outer wall of the clamping plate 25. The sliding rod 24 passes through the fixed seat 1 and is slidably connected to the inner wall of the fixed seat 1. Two sets of limiting plates 21, knobs 22, screw rods 23, sliding rods 24 and clamping plates 25 are respectively provided and are mirrored about the central axis of the fixed seat 1. When the fixed seat 1 is located at the sewage pipe opening, the screw rod 23 is controlled by the left and right sets of knobs 22 to clamp and position the sewage pipe opening.

[0034] Working principle: First, place the fixed seat 1 at the sewage pipe opening. Rotating the two sets of knobs 22 drives the lead screw 23 to rotate. The lead screw 23 pushes the arc-shaped clamp 25 to slide along the slide bar 24, thereby clamping and positioning the sewage pipe opening to ensure stable installation of the detection device. Start motor 2; its output drives the rotating shaft 4 to rotate. Power is transmitted to the screw 6 via the transmission belt 5 and transmission wheel. The screw 6 rotates within the fixed seat 1. Because the movable seat 8 is threadedly connected to the screw 6 and is restricted to sliding along the rod by the limiting rod 7, the movable seat 8 moves axially along the sewage pipe when the screw 6 rotates. When the movable seat 8 moves to the appropriate position, start motor 9. The second gear 10 is driven to rotate by the rotating rod. The first gear 10 meshes with the second gear 11, which in turn drives the support shaft 12 to rotate, causing the turntable 13 to rotate. This allows the detector 20 to perform circumferential detection around the axis of the sewage pipe. If the pitch angle of the detector 20 needs to be adjusted, two sets of electric push rods 15 can be switched on and off. When the electric push rods 15 extend or retract, they push the mounting plate 16 to move. The mounting plate 16 slides in the groove 19 of the adjusting plate 18 through the hinged slide block 17, thereby changing the pitch angle of the adjusting plate 18. This causes the detector 20, which is fixed on the adjusting plate 18, to adjust the detection angle, thus achieving comprehensive detection of the sewage pipe network at different angles and positions.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
