Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a high-efficiency water conservancy engineering dredging pipe head. Background Technology

[0002] Dredging in water conservancy projects generally refers to the process of using mechanical equipment to blow and stir up the deposited silt in rivers, reservoirs, ponds, and water pipelines, turning it into turbid water that is then carried away by the water flow, thereby clearing blockages.

[0003] Currently, Chinese patent application number CN202122456326.3 discloses a dredging pipe head for water conservancy projects, including a connecting rod and a cylindrical barrel. The lower surface of the connecting rod is movably connected to the cylindrical barrel. A fixing plate is fixedly connected to one side of the connecting rod, and a sleeve is fixedly connected to one side of the fixing plate. A spring is fixedly connected to the inner wall of the sleeve, and a connecting plate is fixedly connected to one side of the spring. A sleeve rod is fixedly connected to one side of the connecting plate. A sliding groove is formed on the inner wall of the sleeve, and a slider is slidably connected to the inner wall of the sliding groove.

[0004] However, in the use of existing water conservancy engineering dredging pipe heads, the scraper usually only contacts the inner wall of the water conservancy engineering pipe through the rebound force of the spring. It is not easy to change the overall size of the pipe head that can be extended or retracted, resulting in poor adaptability and flexibility of the dredging pipe head and affecting the efficiency of dredging work. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency dredging pipe head for water conservancy projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency dredging pipe head for water conservancy projects, comprising a base, a mounting base, a servo motor, an extension structure, and a wall scraping structure. The mounting base is fixedly attached to the top right side of the base, and the servo motor is fixedly attached to the top side of the mounting base. The extension structure is connected to the left output end of the servo motor. Wall scraping structures are provided on the front, rear, top, and bottom sides of the extension structure. The right end of the extension structure is rotatably connected to the base. The extension structure includes a shaft connected to the output end of the servo motor on the right side, a positioning frame fixed to the right side of the outer surface of the shaft, a sleeve slidably connected to the left side of the outer surface of the shaft, a screw rod rotating through the sleeve, a support plate fixedly connected to the outer surface of the sleeve, two push rods rotatably connected to the left and right sides of the support plate, a support frame rotatably connected to the top of the push rod, and a slider fixed to the right side of the support frame. The right side of the screw rod is threadedly connected to the inside of the shaft. The top side of the support frame is fixed to the wall scraping structure, and the slider is slidably connected to the inside of the positioning frame.

[0007] Preferably, the positioning frame has a cross-shaped structure, and rectangular through slots are provided on all four sides of the positioning frame.

[0008] Preferably, the slider is I-shaped and there are four of them, and the four sliders slide through the inner sides of the four rectangular slots of the positioning frame.

[0009] Preferably, the support plate, push rod and support frame are provided in four sets, and the positions of the four sets correspond to the four scraping structures respectively.

[0010] Preferably, the sleeve is hollow inside, and a support ring is provided on the left side inside the sleeve, with the screw rotating through the middle side of the support ring.

[0011] Preferably, a columnar groove is provided on the left side inside the shaft, and an internal thread is provided on the inner side of the columnar groove. The outer surface of the screw is threadedly connected to the internal thread in the columnar groove.

[0012] Preferably, the scraping structure includes a rectangular base fixed to the support frame at its bottom, a spring disposed on the bottom side inside the rectangular base, a support block connected to the top of the spring, and a scraper fixedly connected to the top side of the support block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features an optimized extension structure with scraping structures on its front, rear, top, and bottom sides. A servo motor drives the extension and scraping structures to rotate stably on the side of the base, scraping and cleaning the inner wall of the hydraulic pipe. Furthermore, the lateral position of the sleeve can be changed by the cooperation of the screw and shaft inside the extension structure. This allows the four sets of support plates to move stably within the positioning frame, moving the sliders on the sides of the four supports in conjunction with the push rod. This adjusts the height of the four supports, enabling the four scraping structures to extend outwards or retract inwards after the supports move, thus flexibly adapting to hydraulic pipes of different diameters and improving dredging efficiency.

Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 This utility model provides a high-efficiency dredging pipe head for water conservancy projects, including a base 1, a mounting base 2, a servo motor 3, an extension structure 4, and a scraping structure 5. The mounting base 2 is fixedly attached to the top right side of the base 1, and the servo motor 3 is fixedly attached to the top side of the mounting base 2. The extension structure 4 is connected to the left output end of the servo motor 3. The extension structure 4 is provided with scraping structures 5 on its front, back, top, and bottom sides. The right end of the extension structure 4 is rotatably connected to the base 1 so that the extension structure 4 and the scraping structure 5 can be driven by the servo motor 3 to rotate stably on the side of the base 1. The extension structure 4 can also drive the scraping structure 5 to extend outward or retract inward to flexibly adapt to water conservancy project pipes of different diameters and improve the efficiency of dredging.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a high-efficiency dredging pipe head for water conservancy projects. The extended structure 4 includes a shaft 41 connected to the output end of a servo motor 3 on the right side, a positioning frame 42 fixed to the right side of the outer surface of the shaft 41, which rotates under the action of the servo motor 3, a sleeve 43 slidably connected to the left side of the outer surface of the shaft 41, a screw 44 rotating through the sleeve 43, a support plate 45 fixedly connected to the outer surface of the sleeve 43, two push rods 46 rotatably connected to the left and right sides of the support plate 45, and a screw 44 rotatably connected to the push rod 45. The top support 47 and the slider 48 fixed to the right side of the support 47 are connected by a screw 44 to the inside of the shaft 41. The cooperation between the screw 44 and the shaft 41 changes the lateral position of the sleeve 43, thereby allowing the support plate 45 to adjust the height of the support 47 by pushing the push rod 46. The top side of the support 47 is fixed to the scraping structure 5 so that the scraping structure 5 can move outward or inward after the position of the support 47 moves. The slider 48 is slidably connected inside the positioning frame 42 to ensure the stability of the support 47 when it moves in height.

[0025] The positioning frame 42 has a cross-shaped structure, and rectangular slots are provided on all four sides of the positioning frame 42. The sliders 48 are I-shaped and there are four of them. The four sliders 48 slide through the four rectangular slots of the positioning frame 42 to ensure the stability of the sliders 48. The support plate 45, push rod 46 and support frame 47 are provided in four sets, and the positions of the four sets correspond to the four scraping structures 5, so as to drive the four scraping structures 5 to expand outward or retract inward, thereby adapting to different pipe diameters. The engineering tube has a hollow interior for the sleeve 43, and a support ring 431 is provided on the left side inside the sleeve 43. The screw 44 rotates through the middle of the support ring 431 to ensure the stability of the screw 44 during rotation. A columnar groove is provided on the left side inside the shaft 41, and an internal thread 411 is provided on the inner side of the columnar groove. The outer surface of the screw 44 is threadedly connected to the internal thread 411 in the columnar groove. After rotating the screw 44, the screw 44 is laterally displaced at the internal axis of the shaft 41, thereby changing the position of the sleeve 43.

[0026] Please see Figure 1 , Figure 2 and Figure 5This utility model provides a high-efficiency dredging pipe head for water conservancy projects. The wall scraping structure 5 includes a rectangular base 51 whose bottom is fixed to a support frame 47, a spring 52 disposed on the bottom side inside the rectangular base 51, a support block 53 connected to the top of the spring 52, and a scraper 54 fixedly connected to the top side of the support block 53. The left and right sides of the support block 53 are slidably connected to the inner wall of the rectangular base 51, allowing the support block 53 to move in height position inside the rectangular base 51. There are no fewer than five springs 52, which are evenly distributed inside the rectangular base 51, so that the scraper 54 is pressed against the inner wall of the water conservancy project pipe by the rebound force of the springs 52. The top of the scraper 54 is arc-shaped to reduce damage to the inner wall of the water conservancy project pipe.

[0027] The working principle of this utility model for a high-efficiency dredging pipe head for water conservancy projects is as follows:

[0028] First, the design is installed on the water flow engineering pipeline dredging equipment via the base 1 for use;

[0029] Second, according to the inner diameter of the water conservancy project pipeline, the user rotates the screw 44. After rotating the screw 44, the screw 44 is laterally moved at the inner axis of the shaft 41, thereby changing the position of the sleeve 43. After the sleeve 43 moves, the support plate 45 drives the slider 48 on the side of the support frame 47 to move inside the positioning frame 42 through the push rod 46, thereby adjusting the height of the support frame 47. The top side of the support frame 47 is fixed to the scraping structure 5, so that after the positions of the four supports 47 are moved, the four scraping structures 5 are respectively driven to expand outward or retract inward, thereby changing the position of the scraper 54 and making the scraper 54 contact the inner wall of the water conservancy project pipe. When the scraper 54 contacts the inner wall of the water conservancy project pipe, the spring 52 applies a rebound force to the scraper 54 through the support block 53, thereby making the scraper 54 abut against the inner wall of the water conservancy project pipe.

[0030] Third, control the start of the servo motor 3 to make the shaft 41 and the positioning frame 42 rotate on the side of the base 1, thereby scraping and cleaning the inner wall of the water conservancy project pipe.

[0031] The above description is merely 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.
