Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline maintenance technology, specifically, to a water supply and drainage maintenance device. Background Technology

[0002] Water supply and drainage engineering is a core component of urban infrastructure, involving the planning, design, and operation and maintenance of water supply, drainage, sewage treatment, and rainwater harvesting systems. It aims to ensure the safety of residents' domestic water use, effectively discharge wastewater, and prevent environmental pollution. Therefore, regular pipeline inspection is necessary. Currently, before pipeline inspection, it is necessary to use an endoscope to observe the inner wall of the pipeline. The purpose is to achieve non-destructive internal imaging through a high-definition camera, accurately locate the defect location in real time, avoid large-scale excavation operations, improve inspection efficiency and safety, and provide a reliable basis for subsequent maintenance.

[0003] Existing endoscopic devices require operators to hold the device by hand, gradually inserting it into the pipe by holding the end of a telescopic rod. As the tip of the endoscopic device continues to penetrate the pipe, the operator finds it increasingly difficult to hold the pipe end, and the tip is prone to wobbling due to its own weight inside the pipe, resulting in blurred images. If inserted too far, the device may collide with the pipe wall, damaging the precision camera and causing unnecessary losses. Therefore, those skilled in the art provide a water supply and drainage maintenance device to solve the problems mentioned in the background art. Utility Model Content

A worm is rotatably connected to the inner wall of the rotating cavity, and the worm gear and the worm mesh with each other. A rotating rod passes through the side wall of the support rod, and one end of the rotating rod is fixedly connected to one end of the worm.

[0007] As a preferred embodiment of the above technical solution, the fixing component includes a mounting groove, which is located at the center of the end of the support rod away from the telescopic member. Two working chambers are located at the end of the support rod away from the telescopic member, and are situated on both sides of the mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The first and second connecting rods, in conjunction with the rollers, can support the support rod inside the pipe, making it easier for the user to insert the detection component into the pipe. The first and second connecting rods, together with the rollers, form a mechanical fulcrum through the support, allowing the operator to more precisely control the forward and backward trajectory of the detection component, and keeping the detection component centered to avoid collision with the pipe wall and damage to the detection component. At the same time, the support can counteract the shaking caused by the weight of the detection component, ensuring that the detection component maintains a stable posture, thereby obtaining a clear image.

[0015] 2. By rotating the knob, the moving block slides within the sliding cavity through the cooperation of the worm gear, worm wheel, and threaded rod, causing the first and second connecting rods to retract or expand. When the moving sleeve approaches the detection component, the first and second connecting rods retract, and the roller moves away from the support rod. When the moving sleeve moves away from the detection component, the first and second connecting rods expand, and the roller moves closer to the support rod. By adjusting the position of the roller, the roller can be adjusted according to the inner diameter of the pipe, allowing the roller to support the inner wall of pipes with different inner diameters. This enables the device to detect pipes with different inner diameters, improving its practicality.

[0016] 3. The mounting block uses a locking mechanism with a slot for fixation, which significantly improves the efficiency and ease of operation of the testing components. Installation or disassembly can be completed quickly without tools, making it convenient for users to maintain the testing equipment after disassembly and improving the portability of the device.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-5 As shown, this utility model provides a technical solution: a water supply and drainage maintenance device, including a telescopic rod 1, a support rod 2 fixedly connected to the telescopic end of the telescopic rod 1, a support assembly 3 installed on the side wall of the support rod 2, a fixing assembly 4 installed at the end of the support rod 2 away from the telescopic rod 1, a detection assembly 5 installed inside the fixing assembly 4, the support assembly 3 including a plurality of first connecting rods 301, all of the plurality of first connecting rods 301 being hinged to the side wall of the support rod 2, a second connecting rod 302 being hinged to the end of the plurality of first connecting rods 301 away from the support rod 2, a movable sleeve 303 slidably sleeved on the outside of the support rod 2, the ends of the plurality of second connecting rods 302 away from the first connecting rods 301 being hinged to the outer wall of the movable sleeve 303, and a roller 304 fixedly installed on one side of the end of the plurality of second connecting rods 302 away from the support rod 2.

[0025] Furthermore, through the cooperation of the first connecting rod 301 and the second connecting rod 302 with the rollers 304, multiple rollers 304 can abut against the inside of the drainage pipe, thus supporting the support rod 2 inside the pipe. This makes it easier for the user to insert the detection component 5 into the pipe. The first connecting rod 301 and the second connecting rod 302, together with the rollers 304, form a mechanical fulcrum through support, allowing the operator to more precisely control the forward and backward trajectory of the detection component 5, and keeping the detection component 5 running in the center, avoiding the detection component 5 from colliding with the pipe wall and causing equipment damage. At the same time, the support can counteract the shaking caused by the weight of the detection component 5, ensuring that the detection component 5 maintains a stable posture, thereby obtaining a clear image. The telescopic rod 1 is existing technology, consisting of a sleeve, an inner rod, a locking mechanism, and a telescopic drive component. The length adjustment is achieved through a nested structure. Its working principle is that when an external force is applied to the drive component, the inner rod slides along the axial direction of the sleeve and is fixed at the target position by means of the locking mechanism, thereby completing the extension or retraction movement, which will not be elaborated here.

[0026] As one implementation method in this embodiment, please refer to Figure 3 As shown, a sliding cavity 305 is provided inside the support rod 2. Multiple sliding openings 306 are provided on the inner wall of the sliding cavity 305, extending to the outside and communicating with the outside. A threaded rod 307 is rotatably connected to the center of the inner wall of the sliding cavity 305. A movable block 308 is slidably connected inside the sliding cavity 305, slidingly connected within the multiple sliding openings 306, and fixedly connected to the inner wall of the movable sleeve 303. The threaded rod 307 is threadedly sleeved on the movable block 308. At the center, a rotating cavity 309 is provided inside the support rod 2. One end of the threaded rod 307 near the telescopic rod 1 passes through the inner wall of the sliding cavity 305 and is rotatably disposed in the rotating cavity 309. A worm gear 310 is fixedly connected to the end of the threaded rod 307 near the telescopic rod 1. A worm 311 is rotatably connected to the inner wall of the rotating cavity 309. The worm gear 310 and the worm 311 mesh with each other. A rotating rod 312 passes through the side wall of the support rod 2. One end of the rotating rod 312 is fixedly connected to one end of the worm 311.

[0027] Furthermore, by rotating knob 9, worm gear 311 rotates, driving worm wheel 310 to rotate, and threaded rod 307 in sliding cavity 305 rotates, causing moving block 308 to slide in sliding cavity 305 and moving sleeve 303 to slide outside support rod 2, thus causing first connecting rod 301 and second connecting rod 302 to retract or expand. When moving sleeve 303 approaches detection component 5, first connecting rod 301 and second connecting rod 302 retract, and roller 304 moves away from support rod 2. When moving sleeve 303 moves away from detection component 5, first connecting rod 301 and second connecting rod 302 expand, and roller 304 moves closer to support rod 2. By adjusting the position of roller 304, roller 304 can be adjusted according to the inner diameter of the pipe, allowing roller 304 to support the inner wall of pipes with different inner diameters. This enables the device to detect pipes with different inner diameters, improving the practicality of the device.

[0028] As one implementation method in this embodiment, please refer to Figure 4As shown, the fixing component 4 includes a mounting groove 401, which is located at the center of the end of the support rod 2 away from the telescopic rod 1. Two working chambers 402 are located at the end of the support rod 2 away from the telescopic rod 1, and are situated on both sides of the mounting groove 401. A set of springs 403 is fixedly connected to the inner wall of the side of each working chamber 402 away from the mounting groove 401. A locking block 404 is fixedly connected to the front end of each set of springs 403, and the two locking blocks 404 are slidably connected within the two working chambers 402 respectively. Each locking block 404 penetrates one side of the inner wall of the working cavity 402, and the locking ends of the two locking blocks 404 are slidably disposed in the mounting groove 401. A mounting block 405 is placed in the mounting groove 401. The mounting block 405 has a locking groove 406 on both sides. The locking ends of the two locking blocks 404 respectively engage with the two locking grooves 406. Two pull rods 407 penetrate the side wall of the support rod 2, and the two pull rods 407 are slidably disposed in the two working cavities 402 respectively. The two pull rods 407 are respectively fixedly connected to one end of the two locking blocks 404.

[0029] Furthermore, when the user pulls the toggle plate 8, the spring 403 retracts, and the locking end of the locking block 404 retracts into the working cavity 402. The locking end of the locking block 404 is then removed from the slot 406, at which point the mounting block 405 can be taken out. The installation method is the same, which significantly improves the efficiency and ease of operation of the detection component 5. Installation or disassembly can be completed quickly without tools, making it convenient for users to maintain the detection component 5 after disassembly, and improving the portability of the device.

[0030] As one implementation method in this embodiment, please refer to Figure 5 As shown, the detection component 5 includes a mounting housing 501, which is fixedly connected to the end of the mounting block 405 away from the telescopic rod 1. Multiple detection cameras 502 are fixedly mounted on the side wall of the mounting housing 501. An illumination lamp 503 is installed at the end of the mounting housing 501 away from the support rod 2. A lithium battery 504 is installed inside the mounting housing 501, and the lithium battery 504 is disposed on the detection cameras 502 and the illumination lamp 503.

[0031] Furthermore, the detection component 5 is pushed into the pipe using the telescopic rod 1. The lighting lamp 503 illuminates the inner wall of the pipe, and the detection camera 502 detects the inner wall of the pipe to determine whether the inner wall of the pipe is damaged. The detection camera 502 is existing technology and mainly consists of a high-definition camera and a transmission device. The camera is equipped with a wide-angle lens to capture images of the inner wall of the pipe. The lighting lamp 503 provides uniform illumination, and the images are transmitted wirelessly to the ground equipment in real time. The lithium battery 504 continuously supplies power to the lighting lamp 503 and the detection camera 502. Details will not be elaborated here. The inner wall of the mounting shell 501 is provided with heat-conducting fins to cool the lithium battery 504 and prevent it from overheating. The mounting shell 501 is provided with a charging port for charging the lithium battery 504, and a rubber pad is provided inside the charging port for protection. Details will not be elaborated here.

[0032] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, the end of the telescopic rod 1 away from the support rod 2 is fixedly connected to a fixed rod 6, and a handle 7 is fixedly connected to the side wall of the fixed rod 6.

[0033] Furthermore, the fixed rod 6 and handle 7 make it easier for users to hold the telescopic rod 1 and operate the telescopic rod 1 to extend and retract, thus improving the portability of the device.

[0034] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, both pull rods 407 are fixedly connected to a toggle plate 8 on the side away from the mounting groove 401, and both toggle plates 8 have toggle openings.

[0035] Furthermore, the toggle plate 8 facilitates user operation of the lever 407, thereby further enhancing the portability of the device.

[0036] As one implementation method in this embodiment, please refer to Figure 4 As shown, the inner wall of the mounting groove 401 is provided with an anti-slip pad layer, and the anti-slip pad layer is made of hard rubber.

[0037] Furthermore, the friction between the mounting groove 401 and the mounting block 405 is increased, which improves the stability of the mounting block 405 within the mounting groove 401, thereby improving the stability of the detection component 5.

[0038] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a knob 9 is fixedly connected to the end of the rotating rod 312 away from the worm gear 311.

[0039] Furthermore, the knob 9 makes it easier for users to rotate the lever 312, improving the portability of the device.

[0040] Working principle: The first connecting rod 301 and the second connecting rod 302, together with the rollers 304, support the support rod 2. Multiple rollers 304 can rest against the inside of the drainage pipe, facilitating the insertion of the detection component 5 into the pipe. The first connecting rod 301, the second connecting rod 302, and the rollers 304 form a mechanical fulcrum through support, allowing the operator to more precisely control the forward and backward trajectory of the detection component 5, and keeping the detection component 5 centered, preventing it from colliding with the pipe wall and causing equipment damage. Simultaneously, the support can offset the detection... The swaying caused by the weight of component 5 ensures that the detection component 5 maintains a stable posture, thereby obtaining a clear image. By rotating knob 9, worm gear 311 rotates, driving worm wheel 310 to rotate, and threaded rod 307 in sliding cavity 305 rotates, causing moving block 308 to slide within sliding cavity 305 and moving sleeve 303 to slide outside support rod 2, thus causing first connecting rod 301 and second connecting rod 302 to retract or expand. When moving sleeve 303 approaches detection component 5, first connecting rod 301 and second connecting rod 302 retract, and roller 304 moves away. As the movable sleeve 303 moves away from the detection component 5, away from the support rod 2, the first connecting rod 301 and the second connecting rod 302 unfold, and the roller 304 approaches the support rod 2. By adjusting the position of the roller 304, it can be adjusted according to the inner diameter of the pipe, allowing the roller 304 to support the inner wall of pipes with different inner diameters. This enables the device to detect pipes with different inner diameters, improving the device's practicality. Subsequently, the telescopic rod 1 is used to push the detection component 5 into the pipe, and the illumination lamp 503 illuminates the inner wall of the pipe, and the detection camera... 502 inspects the inner wall of the pipe to determine if it is damaged. After the device is used, the user pulls the actuating plate 8, the spring 403 retracts, and the locking end of the locking block 404 retracts into the working chamber 402. The locking end of the locking block 404 moves out of the slot 406, at which point the mounting block 405 can be removed. The installation method is the same, which significantly improves the efficiency and ease of operation of the detection component 5. Installation or disassembly can be completed quickly without tools, making it convenient for users to maintain the detection component 5 after disassembly, and improving the portability of the device.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
