Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection endoscope technology, specifically a rainwater pipeline inspection endoscope with self-cleaning function. Background Technology

[0002] Municipal drainage systems require rainwater pipes. To ensure proper drainage and sewage discharge, regular inspections of the pipe interior are necessary. Due to the narrow diameter of the pipes, endoscopic devices capable of moving inside the rainwater pipes are required. These devices are equipped with wheels, cameras, remote transmission modules, and power supplies, enabling them to travel long distances and continuously within the pipes. The cameras remotely transmit video images from inside the pipes to the client.

[0003] Utility model CN209417316U discloses a remotely controlled pipe endoscope, comprising a main body, a 360-degree panoramic camera, a wheel support rod, a walking wheel frame, and walking wheels. The 360-degree panoramic camera is fixedly mounted at the front end of the main body. The main body is equipped with a data processing and conversion device connected to a communication cable or wireless signal input / output device. The signal output interface of the 360-degree panoramic camera is electrically connected to the data processing and conversion device. A spring mounting bracket is fixed in the middle of the main body. This utility model has a reasonable and compact structure and is easy to use. It uses a drive motor to rotate the walking wheels and allows for real-time dynamic observation of the foreground through the 360-degree panoramic camera, enabling long pipe penetration distances. By adjusting the angle of the video head, a wide range of real-time observation of the manhole's interior can be achieved. It can also cross smaller obstacles, featuring good obstacle clearance, high reliability, labor-saving, simplicity, and high efficiency.

[0004] However, the existing technology has its shortcomings in use: the rainwater pipes are not only humid but also contain dirt (sludge, weeds, etc.), which makes it easy for water droplets and dirt to adhere to the lens surface of the 360-degree panoramic camera, thus affecting the clarity of the image.

[0005] Therefore, this utility model provides an endoscope for inspecting rainwater pipes with a self-cleaning function. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rainwater pipe inspection endoscope with self-cleaning function to solve the problems mentioned in the background technology. This utility model has the function of cleaning and blocking dirt during image acquisition, thus ensuring the clarity of the image acquisition.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an endoscope for inspecting rainwater pipes with a self-cleaning function, comprising a device body, an adapter seat at the front end of the device body, a positioning plate fixedly mounted on the front side of the adapter seat, a camera and a hemispherical transparent cover mounted in the middle of the front side of the positioning plate, the camera being housed within the hemispherical transparent cover, the opening of the hemispherical transparent cover being rotatably connected to the positioning plate, a support rod located on one side of the hemispherical transparent cover mounted on the front side of the positioning plate, one end of the support rod being rotatably connected to the positioning plate, and a rubber scraper fixedly mounted on one side of the support rod.

[0008] Furthermore, a positioning platform located inside a hemispherical transparent cover is fixedly connected to the front side of the positioning disk, and the base of the camera is fixedly connected to the front end of the positioning platform.

[0009] Furthermore, the opening of the hemispherical transparent cover is fixedly connected to a docking sleeve, and the front side of the positioning disk is fixedly fitted with a support sleeve that is fitted inside the docking sleeve. The support sleeve and the docking sleeve are rotatably sealed together.

[0010] Furthermore, a sealing ring is fitted between the support sleeve and the mating sleeve.

[0011] Furthermore, the outer fixed sleeve of the support sleeve is provided with a gear ring, and the back of the positioning disk is fixedly connected to a control motor. The output shaft of the control motor passes through the positioning disk and is fixedly connected to a gear that meshes with the gear ring.

[0012] Furthermore, a support is fixedly connected to the front side of the positioning disk, and one end of the support and the strut are hinged together with a torsion spring at the hinge. An electric push rod is fixedly connected to the back of the positioning disk, and the output shaft of the electric push rod passes through the positioning disk and abuts against the side of the strut that is away from the rubber scraper.

[0013] Furthermore, the adapter has a wire channel inside, one end of which is connected to the inner cavity of the hemispherical transparent cover.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a positioning plate is provided, and a hemispherical transparent cover is provided on the front side of the positioning plate. The camera is housed in the hemispherical transparent cover, and the hemispherical transparent cover and the positioning plate are rotatably connected. Then, a support rod is provided on the front side of the positioning plate, located outside the hemispherical transparent cover. A rubber scraper is provided on one side of the support rod. The hemispherical transparent cover serves to prevent dirt (water droplets and mud, etc.) from directly blocking the camera lens. When dirt is attached to the hemispherical transparent cover, the rotation of the hemispherical transparent cover is controlled, and the rubber scraper can scrape off the dirt attached to the outside of the hemispherical transparent cover, thereby ensuring that the camera captures clear images.

[0016] 2. In this utility model, when the hemispherical transparent cover rotates in one direction, the dirt on it will accumulate on one side of the rubber scraper. This design can effectively prevent the dirt accumulated on the rubber scraper from causing secondary contamination of the hemispherical transparent cover, thus greatly improving the cleanliness of the hemispherical transparent cover after cleaning.

[0017] 3. In this utility model, the support rod and the positioning plate are rotatably connected. When the support rod rotates away from the hemispherical transparent cover, the support rod and the rubber scraper will not obstruct the camera's view. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5This utility model provides a technical solution: an endoscope for inspecting rainwater pipes with a self-cleaning function, comprising a device body 1. The power supply, communication, and mobility structures on the device body 1 can all adopt the structures mentioned in the patent documents in the background art. In this technical solution, an adapter 2 is provided at the front end of the device body 1, and a positioning plate 3 is fixedly provided on the front side of the adapter 2. A camera 4 and a hemispherical transparent cover 5 are provided in the middle of the front side of the positioning plate 3. The camera 4 is housed in the hemispherical transparent cover 5. The hemispherical transparent cover 5 can be a resin glass cover or a cover supported by other transparent materials that do not affect the image clarity. The hemispherical transparent cover 5 serves to protect the camera 4 and at the same time prevents dirt from directly adhering to the lens of the camera 4.

[0026] The opening of the hemispherical transparent cover 5 is rotatably connected to the positioning disk 3. A support rod 6 is located on the front side of the positioning disk 3, positioned on one side of the hemispherical transparent cover 5. A rubber scraper 7 is fixedly mounted on one side of the support rod 6. One side of the rubber scraper 7 is curved, and the scraper 7 contacts the outer wall of the hemispherical transparent cover 5 through this curved surface, thereby increasing the coverage area of ​​the scraper. In use, the rubber scraper 7 is kept stationary, and then the hemispherical transparent cover 5 is rotated. At this time, the dirt attached to the outer wall of the hemispherical transparent cover 5 will be scraped off. It should be noted that some of the scraped dirt will adhere to one side of the rubber scraper 7. When the hemispherical transparent cover 5 rotates in one direction, this part of the dirt will not re-contaminate the hemispherical transparent cover 5, ensuring the cleanliness of the hemispherical transparent cover 5 after cleaning.

[0027] Furthermore, one end of the support rod 6 is rotatably connected to the positioning plate 3. When the support rod 6 rotates away from the hemispherical transparent cover 5, it will drive the rubber scraper 7 away from the hemispherical transparent cover 5. Thus, the support rod 6 and the rubber scraper 7 will not block the image capture line of the protective camera 4.

[0028] Specifically, a support 33 is fixedly connected to the front side of the positioning disk 3. The support 33 and one end of the support rod 6 are hinged together, and a torsion spring 102 is provided at the hinge. The function of the torsion spring 102 is to continuously apply an elastic thrust to the support rod 6 to move away from the hemispherical transparent cover 5. An electric push rod 103 is fixedly connected to the back side of the positioning disk 3. The output shaft of the electric push rod 103 passes through the positioning disk 3 and abuts against the side of the support rod 6 away from the rubber scraper 7. When the electric push rod 103 pushes, its output shaft will push the support rod 6 to swing towards the hemispherical transparent cover 5. In specific implementation, an arc-shaped pad can be welded to the side of the support rod 6 away from the rubber scraper 7. When in use, the arc-shaped pad abuts against the output shaft end of the electric push rod 103. Thus, the electric push rod 103, together with the torsion spring 102, can control the swing of the support rod 6.

[0029] In this embodiment, a positioning platform 31 located inside a hemispherical transparent cover 5 is fixedly connected to the front side of the positioning disk 3. The base of the camera 4 is fixedly connected to the front end of the positioning platform 31. The camera 4 adopts a structure with 360° panoramic imaging function to increase and expand the field of view of on-site imaging.

[0030] In this embodiment, a docking sleeve 51 is fixedly connected to the opening of the hemispherical transparent cover 5, and a support sleeve 32 is fixedly fitted inside the docking sleeve 51 on the front side of the positioning disk 3. The support sleeve 32 and the docking sleeve 51 are rotated and sealed together. In specific implementation, a sealing ring 8 and a bearing are fitted between the support sleeve 32 and the docking sleeve 51, thereby preventing water vapor from entering the hemispherical transparent cover 5 and affecting the image acquisition line of sight.

[0031] Furthermore, a gear ring 9 is fixedly fitted on the outside of the support sleeve 32, and a control motor 101 is fixedly connected to the back of the positioning disk 3. The output shaft of the control motor 101 passes through the positioning disk 3 and is fixedly connected to a gear 1011 that meshes with the gear ring 9. The control motor 101 drives the hemispherical transparent cover 5 to rotate through the meshing of the gear 1011 and the gear ring 9. In use, the control motor 101 is remotely connected to the client's controller through the communication system on the device body 1, which facilitates remote operation of the control motor 101.

[0032] In this embodiment, the adapter 2 has a wire channel 21. One end of the wire channel 21 is connected to the inner cavity of the hemispherical transparent cover 5. The wires connected to the camera 4 are electrically connected to the connector part in the device body 1 through this wire channel 21. After the wires pass through the wire channel 21, sealant can be injected into the wire channel 21 for sealing.

[0033] Working principle: When the device body 1 carrying the adapter 2 moves inside the rainwater pipe, if dirt adheres to the outer wall of the hemispherical transparent cover 5 and obstructs the camera 4's line of sight, the control motor 101 is activated. The hemispherical transparent cover 5 rotates at high speed, which can centrifugally shake off the dirt on it to achieve self-cleaning. When the dirt is difficult to shake off, the electric push rod 103 is controlled to move to push the support rod 6 to swing to the side of the rubber scraper 7 and the outer wall of the hemispherical transparent cover 5. At this time, the rubber scraper 7 can scrape off the dirt that is difficult to separate from the hemispherical transparent cover 5, thus achieving the self-cleaning function.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
