Description

Technical Field

[0001] This utility model relates to municipal water conservancy pipelines, and in particular to a municipal water conservancy pipeline dredging device, belonging to the field of pipeline dredging technology. Background Technology

[0002] Municipal water conservancy pipeline dredging equipment is a type of specialized mechanical equipment used to remove sediment and debris from urban water supply and drainage pipelines, stormwater and sewage pipe networks, and other municipal water conservancy facilities, and to unclog blocked channels.

[0003] Publication number CN221682064U discloses a municipal water conservancy pipeline dredging device, belonging to the field of pipeline cleaning technology. It includes an installation rod, with an installation sleeve fixedly installed on the outer wall of the rod. A motor is fixedly installed on one side of the installation sleeve, and a gear is fixedly connected to the output shaft of the motor. A sleeve is rotatably connected to the top of the installation rod, and a toothed ring is fixedly connected to the bottom end of the sleeve. An installation disc is fixedly connected to the top surface of the sleeve. In this invention, a scraper is installed inside. By rotating a nut, the scraper contacts the inner wall of the pipeline. Starting the motor causes the output shaft to rotate, driving the gear to rotate. The gear, through the toothed ring, drives the sleeve to rotate, which in turn drives the installation disc to rotate, thus rotating the scraper. This design effectively cleans the sludge from the inner wall of the pipeline, preventing re-blockage after dredging and reducing subsequent dredging costs.

[0004] However, the aforementioned unblocking device has significant shortcomings in its use. First, before unblocking operations, the nut must be manually rotated to ensure the four scraper blades are in contact with the inner wall of the pipe. This process requires not only ensuring the scraper blades are in close contact with the pipe wall but also maintaining the drill bit in the pipe's axis position, making the operation cumbersome. Due to the lack of precise control methods, the accuracy of manual adjustment is difficult to guarantee. If the scraper blades do not make uniform contact with the pipe wall, force imbalance can easily occur during rotation, severely affecting the unblocking effect. Second, the device lacks a quick-change mechanism between the drill bit and the output motor. For pipes of different diameters, it is impossible to promptly replace the drill bit with the appropriate specification, greatly limiting the equipment's applicability and operational efficiency, thus requiring improvement.

[0005] Therefore, a municipal water conservancy pipeline dredging device is proposed. Utility Model Content

[0006] In view of this, the present invention provides a municipal water conservancy pipeline dredging device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A municipal water conservancy pipeline dredging device includes a connecting rod, a base plate installed on the connecting rod, a connecting disc installed below the base plate, a frame plate installed on the base plate, a slider slidably installed inside the frame plate, a protruding rod installed below the slider, the protruding rod penetrating the base plate and extending to the bottom of the base plate, a connecting cover installed above the slider, a top plate installed on the connecting cover, a scraper slidably installed inside the top plate, a spring A installed inside the top plate, a grooved disc rotatably installed below the base plate, the grooved disc rotatably installed inside the connecting disc, a worm gear rotatably installed on the connecting disc, a motor A installed on the connecting disc, a worm wheel meshing on the side of the worm gear, an mounting plate installed on the connecting rod, a gear ring installed below the connecting disc, a motor B installed on the mounting plate, a gear installed at the output end of the motor B, a motor C installed inside the connecting rod, and a drill bit connected to the output end of the motor C through a quick-change mechanism.

[0008] More preferably, one end of the worm gear is installed at the output end of the motor A, the worm wheel is installed below the slotted plate, and the gear meshes with the gear ring.

[0009] More preferably, the tray is provided with multiple sets of guide grooves, and the protruding rod is disposed in the guide groove.

[0010] In a further preferred embodiment, the connecting rod is provided with a sewage guiding channel, and the connecting rod is connected to a sludge suction pipe, which is connected to the sewage guiding channel.

[0011] More preferably, one end of the spring A is installed inside the top plate, and the other end of the spring A is installed on the back of the scraper, and the spring A drives the scraper to tend to move away from the top plate.

[0012] More preferably, the quick-change mechanism includes an installation rod, a grooved rod, a sleeve, a stop plate, a guide rod, and a spring B. The installation rod is installed at the output end of the motor C, the grooved rod is installed below the drill bit, the sleeve is installed on the installation rod, the stop plate is slidably installed inside the sleeve, the guide rod is installed below the stop plate, and the spring B is sleeved on the guide rod. The spring B drives the stop plate to tend to move closer to the grooved rod.

[0013] More preferably, the grooved rod is provided with a slot, and the top of the mounting rod is provided with a plug that matches the slot. The slot and the plug are T-shaped.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model not only demonstrates superior performance in pipe unblocking, efficiently removing blockages, but also simultaneously scrapes away sediment from the pipe walls, significantly improving the unblocking effect. Furthermore, driven by motor A, multiple sets of scrapers can be precisely controlled to extend and retract synchronously along the frame plate direction. This not only enables rapid contact between the scrapers and the inner walls of pipes of different diameters, greatly improving adjustment accuracy, but also ensures that the drill bit remains on the central axis of the connecting rod, effectively avoiding the risk of uneven force during rotational operation and improving the unblocking effect.

[0016] Second, this utility model features a quick-change drill bit mechanism. When dealing with pipes of different diameters, pulling down the abutment plate quickly releases the locking state of the mounting rod and the slotted rod, enabling rapid disassembly and replacement of drill bits of different specifications. This not only solves the problem of insufficient applicability caused by the limited drill bit specifications in traditional equipment, but also significantly improves work efficiency and enhances the practicality and versatility of the equipment.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this utility model embodiment provides a municipal water conservancy pipeline dredging device, including a connecting rod 1, a base plate 2 installed on the connecting rod 1, a connecting plate 3 installed below the base plate 2, a frame plate 4 installed on the base plate 2, a slider 5 slidably installed inside the frame plate 4, a protruding rod 6 installed below the slider 5, the protruding rod 6 penetrating the base plate 2 and extending to the bottom of the base plate 2, a connecting cover 7 installed above the slider 5, a top plate 8 installed on the connecting cover 7, a scraper 9 slidably installed inside the top plate 8, and a spring A10 provided inside the top plate 8. A grooved disc 11 is rotatably mounted below the connecting disc 3. A worm gear 13 is rotatably mounted on the connecting disc 3. A motor A14 is mounted on the connecting disc 3. A worm wheel 15 is meshed on the side of the worm gear 13. A mounting plate 16 is mounted on the connecting rod 1. A gear ring 17 is mounted below the connecting disc 3. A motor B18 is mounted on the mounting plate 16. A gear 19 is mounted on the output end of the motor B18. A motor C22 is mounted inside the connecting rod 1. A drill bit 21 is connected to the output end of the motor C22 through a quick-change mechanism.

[0029] In one embodiment, one end of the worm 13 is mounted on the output end of the motor A14, the worm wheel 15 is mounted below the grooved disc 11, and the gear 19 meshes with the gear ring 17. Starting the motor A14 drives the worm 13 to rotate, which in turn drives the worm wheel 15 and the grooved disc 11 to rotate along the axis.

[0030] In one embodiment, the slotted plate 11 is provided with multiple sets of guide grooves 12, and the protruding rod 6 is disposed within the guide grooves 12. During the rotation of the slotted plate 11 along its axis, the position of the guide grooves 12 changes, and under the mechanical coupling between the guide grooves 12 and the protruding rod 6, multiple sets of sliders 5 are driven to slide synchronously along the frame plate 4.

[0031] In one embodiment, a sludge guiding channel is provided inside the connecting rod 1, and the connecting rod 1 is connected to a sludge suction pipe 20, which is connected to the sludge guiding channel. The sludge will eventually enter the sludge suction pipe 20 through the sludge guiding channel on the connecting rod 1.

[0032] In one embodiment, one end of spring A10 is installed inside the top plate 8, and the other end of spring A10 is installed on the back of scraper 9. Spring A10 drives scraper 9 to tend to move away from top plate 8. Under the action of spring A10, top plate 8 is ensured to always be in contact with the inner wall of the pipe, and then the sludge on the inner wall of the pipe can be effectively scraped off during the rotation of scraper 9.

[0033] In one embodiment, the quick-change mechanism includes a mounting rod 23, a slotted rod 24, a sleeve 25, a stop plate 26, a guide rod 27, and a spring B28. The mounting rod 23 is mounted on the output end of the motor C22, the slotted rod 24 is mounted below the drill bit 21, the sleeve 25 is mounted on the mounting rod 23, the stop plate 26 is slidably mounted inside the sleeve 25, the guide rod 27 is mounted below the stop plate 26, and the spring B28 is sleeved on the guide rod 27. The spring B28 drives the stop plate 26 to tend to move closer to the slotted rod 24. By setting up a quick-change mechanism for the drill bit 21, different specifications of drill bits 21 can be quickly disassembled and replaced when dealing with pipes of different diameters. This solves the problem of insufficient applicability caused by the limited specifications of the drill bit 21 in traditional equipment. The height of the drill bit 21 is higher than that of the stop plate 26, and during crushing operations, the material to be crushed first contacts the drill bit 21 and is then extracted by the lower suction pipe 20, preventing direct contact with the stop plate 26.

[0034] In one embodiment, a slot 29 is provided inside the groove rod 24, and a plug 30 adapted to the slot 29 is provided at the top of the mounting rod 23. The slot 29 and the plug 30 are T-shaped. The T-shaped plug 30 and the slot 29 have a vertical limiting effect, high stability, and simple installation and operation.

[0035] In operation, this invention first adjusts the scraper 9 and replaces the drill bit 21 according to the inner diameter of the pipe to be dredged. When replacing the drill bit 21, first pull down the abutment plate 26 and let it slide down along the sleeve 25. During this process, the guide rod 27 will extend downwards, and the spring B28 will deform simultaneously until the abutment plate 26 no longer abuts against the connection between the groove rod 24 and the mounting rod 23. Then, the drill bit 21 can be moved along the slot 29 on the groove rod 24 to remove it from the mounting rod 23, thus completing the removal of the original drill bit 21. During installation... First, pull down the abutment plate 26 to expose the insert block 30 on the mounting rod 23. Then, align and insert the slot 29 on the groove rod 24. Then, release the abutment plate 26. At this time, under the action of the spring B28, the abutment plate 26 will slide upward and push against the connection between the groove rod 24 and the mounting rod 23, thus completing the locking and limiting work. The height of the drill bit 21 is higher than the abutment plate 26. During the crushing operation, the material to be crushed first contacts the drill bit 21 and is pulled out with the lower suction pipe 20. It cannot directly contact the abutment plate 26. Then, adjust the scraper 9. At this time, start the electric... Machine A14 drives the worm gear 13 to rotate, which in turn drives the worm wheel 15 and the grooved disc 11 to rotate along the axis. During this process, the position of the guide groove 12 changes, and under the mechanical coupling between the guide groove 12 and the protruding rod 6, multiple sets of sliders 5 slide synchronously along the frame plate 4. This enables the scraper 9 to quickly fit against the inner wall of pipes of different diameters, and ensures that the drill bit 21 is always on the central axis of the connecting rod 1, effectively avoiding the risk of uneven force during rotation. During operation, the drive motor B18 drives the gear 19 to rotate. At this time, the gear 19 meshes with the gear ring 17. The action will drive the connecting plate 3 and the base plate 2 to rotate. At this time, due to the locking effect between the worm gear 13 and the worm wheel 15, the groove plate 11 can be driven to rotate at the same time as the connecting plate 3 rotates. At the same time, the scraper 9 above will be driven to scrape. Under the action of the spring A10, the top plate 8 is always in contact with the inner wall of the pipe. Then, during the rotation of the scraper 9, the sludge on the inner wall of the pipe can be effectively scraped off. When the motor C22 drives the drill bit 21 to rotate, the blockage point can be quickly cleared. At the same time, the sludge will eventually enter the sludge suction pipe 20 through the sludge guide channel on the connecting rod 1.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
