Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection structure technology, and in particular to a pipeline inspection structure for water conservancy projects. Background Technology

[0002] The use of drainage pipes is essential in water conservancy projects. In order to facilitate internal inspection and avoid potential hazards, it is necessary to use inspection devices to inspect them.

[0003] To address this, patent CN207540983U discloses a multifunctional pipeline inspection system structure, including a main unit, a cable retraction device, a floating raft, and a cable. The cable retraction device is mounted on the main unit. The floating raft is separate from the main unit and is equipped with a data acquisition device. The cable is wound around the cable retraction device, with one end electrically connected to the main unit and the other end fixedly connected to the floating raft. The data acquisition device is also electrically connected to the cable. By incorporating a cable retraction device on the main unit, the cable can be automatically retracted and deployed, replacing the traditional manual retraction. Furthermore, an automatic walking device is installed at the bottom of the floating raft, allowing it to move even in shallow water. This simplifies the inspection process, requiring only one operator.

[0004] The aforementioned detection device is difficult to move quickly in sewer pipes of different sizes during use, and the detection components are difficult to protect, which limits its application. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline inspection structure for water conservancy projects, which solves the shortcomings of existing pipeline inspection structures that are not convenient for quick movement inside pipelines and for protecting inspection components.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pipeline inspection structure for water conservancy projects, comprising a main body and a fixing ring;

[0007] A fixing ring is fixed to the top of the main body, and an adjustment structure is installed inside the main body;

[0008] The adjustment structure includes an adjustment motor installed inside the main body. A drive gear is provided on one side of the adjustment motor. Driven gears are evenly arranged on the outer wall of the drive gear. A double-acting lead screw is provided on one side of each driven gear. A moving block is provided on the outer wall of each double-acting lead screw. A support rod is hinged to the top of each moving block. A moving track is hinged to one side of each support rod.

[0009] A protective structure is installed at the bottom of the main body.

[0010] Preferably, the driven gears are evenly distributed on the outer wall of the driving gear, and the driving gear and the driven gear mesh with each other.

[0011] Preferably, the moving blocks are symmetrically distributed on the outer wall of the bidirectional lead screw, and each moving block is threadedly connected to the bidirectional lead screw.

[0012] Preferably, the mobile tracks are evenly spaced on the outer side of the main body.

[0013] Preferably, the protective structure includes a detection camera installed at the bottom of the main body, a lighting fixture installed at the bottom of the main body on one side of the detection camera, a reserved groove opened at the bottom of the main body on the outer side of the detection camera, a protective cover installed inside the reserved groove, a snap-fit ​​hole opened at the top of the protective cover, an internal groove opened inside the main body on one side of the reserved groove, a snap-fit ​​rod installed inside the internal groove, and a return spring fixed on one side of the snap-fit ​​rod.

[0014] Preferably, the snap-fit ​​holes are symmetrically distributed on the top of the protective cover, and the protective cover is rotatably connected inside the reserved slot.

[0015] Preferably, the locking rod is disposed inside the locking hole, and the locking rod and the protective cover form a locking structure through the locking hole.

[0016] The present invention provides a pipeline inspection structure for water conservancy projects, the advantages of which are:

[0017] By setting an adjustment structure, starting the adjustment motor causes the drive gear to rotate, which in turn drives the driven gear and the double-sided lead screw to rotate synchronously, thereby causing two sets of moving blocks to move towards each other on their outer walls. The top of the moving block is hinged to a support rod, and one side of the support rod is hinged to the moving track. Thus, when the position of the moving block changes, the support rod pushes the moving track to change the position, thereby achieving the purpose of facilitating the movement of the device inside pipes of different sizes.

[0018] By incorporating a protective structure, the device protects the detection components with a protective cover. This facilitates the insertion of the protective cover into the pre-drilled slot and its rotation, which presses the locking rod into the built-in slot. The locking rod is influenced by the push of the return spring, and when the locking hole moves to one side, it facilitates pushing the locking rod into the locking hole to engage and position the protective cover. This achieves the purpose of facilitating the use of a protective cover to protect the detection camera and to facilitate the installation, removal, and positioning of the protective cover.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides a pipeline inspection structure for water conservancy projects, comprising a main body 1 and a fixing ring 2.

[0027] Reference Figures 1-3 As shown, a fixing ring 2 is fixed to the top of the main body 1. An adjustment structure 3 is installed inside the main body 1. The adjustment structure 3 includes an adjustment motor 301 installed inside the main body 1. A drive gear 302 is provided on one side of the adjustment motor 301. Driven gears 303 are evenly arranged on the outer wall of the drive gear 302. A double-acting lead screw 304 is provided on one side of each driven gear 303. A moving block 305 is provided on the outer wall of each double-acting lead screw 304. A support rod 306 is hinged to the top of each moving block 305. A moving track 307 is hinged to one side of each support rod 306. The driven gears 303 are evenly distributed on the outer wall of the drive gear 302. The drive gear 302 and the driven gear 303 mesh with each other. The moving blocks 305 are symmetrically distributed on the outer wall of the double-acting lead screw 304. The moving blocks 305 are all threadedly connected to the double-acting lead screw 304. The moving track 307 is evenly distributed on the outer side of the main body 1.

[0028] To facilitate inspection of sewer pipes, the device needs to be placed inside the pipe. To prevent it from being difficult to remove in case of an accident, a rope is pre-installed inside the fixing ring 2 for easy pulling out. To facilitate the movement of the device inside pipes of different sizes, an adjustment structure 3 is provided. This allows the moving tracks 307, which are evenly spaced on the outside of the main body 1, to be activated, providing the power for the device's movement. The activation of the adjustment motor 301 causes the drive gear 302 to drive the driven gear 303 to rotate. A two-way lead screw 304 is provided on one side of the driven gear 303, causing it to rotate synchronously. The moving blocks 305 are threadedly connected to the lead screw 304, allowing the two sets of moving blocks 305 to move towards each other on their outer walls. The support rod 306, hinged to the top of the moving blocks 305, is also hinged to the moving tracks 307. When the moving blocks 305 push the support rod 306 to change position, they can easily push the moving tracks 307 to change position, thus greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a protective structure 4 is installed at the bottom of the main body 1. The protective structure 4 includes a detection camera 401 installed at the bottom of the main body 1. A lighting fixture 402 is installed at the bottom of the main body 1 on one side of the detection camera 401. A reserved groove 403 is opened at the bottom of the main body 1 outside the detection camera 401. A protective cover 404 is set inside the reserved groove 403. A snap-fit ​​hole 405 is opened on the top of the protective cover 404. An internal groove 406 is opened inside the main body 1 on one side of the reserved groove 403. A snap-fit ​​rod 407 is set inside the internal groove 406. A return spring 408 is fixed on one side of the snap-fit ​​rod 407. The snap-fit ​​holes 405 are symmetrically distributed on the top of the protective cover 404. The protective cover 404 is rotatably connected inside the reserved groove 403. The snap-fit ​​rod 407 is set inside the snap-fit ​​hole 405. The snap-fit ​​rod 407 and the protective cover 404 form a snap-fit ​​structure through the snap-fit ​​hole 405.

[0030] When inspecting the inside of a pipeline, a camera 401 captures images of the internal conditions, while a lighting fixture 402 provides illumination. Since the inside of the pipeline may contain debris or other objects that could cause damage, protection is necessary. A protective structure 4 is installed, allowing a protective cover 404 to be placed inside a pre-reserved slot 403 and positioned by a locking mechanism formed by a locking rod 407 and a locking hole 405. This protects the camera 401 and the lighting fixture 402. The locking rod 407 has a semi-circular design on one side; rotating the protective cover 404 forces the locking rod 407 into the internal slot 406, releasing the locking mechanism. This facilitates the removal and replacement of the protective cover 404 and the inspection and maintenance of the camera 401 and the lighting fixture 402, greatly increasing the practicality of the device.

[0031] Although the present invention 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 invention should be included within the protection scope of the present invention.
