Description

Technical Field

[0001] This utility model relates to the technical field of interception devices in water conservancy construction, specifically an interception device used in water conservancy construction. Background Technology

[0002] The term "water diversion device" in water conservancy construction refers to the collective term for equipment used in water conservancy construction to divert rivers. These devices include dump trucks, loaders, cranes, bulldozers, vibrating screens, and transport ships. Dump trucks are commonly used transport tools in water diversion construction, responsible for transporting various diversion materials from the quarry to the diversion point. Loaders can quickly collect and gather scattered stones, sand, and other materials from the quarry using their buckets. Cranes can lift large prefabricated components and place them precisely in the river. Vibrating screens are used for pre-treatment of diversion materials, separating sand and gravel from different particle sizes. Smaller particles can be used to pave the foundation of the embankment, optimizing the quality of the diversion materials. Oversized particles are crushed and reused.

[0003] In existing technologies, the vibrating screen in the interception device of water conservancy construction can screen sand and gravel. However, the large pieces of sand and gravel screened out will accumulate on the metal screen, requiring workers to clean the large pieces of sand and gravel on the metal screen regularly to ensure the efficiency of sand and gravel screening. This results in high labor intensity for workers and affects the efficiency of sand and gravel screening. Therefore, an interception device for water conservancy construction is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a diversion device for water conservancy construction. It has the advantage of automatically cleaning large pieces of sand and gravel from a metal screen, solving the problem that while vibrating screens in water conservancy construction diversion devices can screen sand and gravel, large pieces of sand and gravel accumulate on the metal screen, requiring workers to regularly clean them to ensure the efficiency of sand and gravel screening. This results in high labor intensity for workers and affects the efficiency of sand and gravel screening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diversion device for water conservancy construction, comprising a screening machine, wherein a metal screen is provided inside the screening machine, a support bracket is provided outside the screening machine, and a cleaning structure and a control structure are provided on the top of the screening machine;

[0006] The cleaning structure includes a mounting frame fixedly installed on the top of the screening machine. A connecting block is slidably installed inside the mounting frame. A connecting bracket is fixedly installed on the front of the connecting block, with one end penetrating and extending into the interior of the screening machine. A cleaning plate for cleaning large pieces of sand and gravel is fixedly installed on the connecting bracket, located on top of the metal screen. A guide component for limiting the movement trajectory of the connecting block is provided inside the mounting frame. Two limiting plates for limiting the left and right movement range of the connecting bracket are fixedly installed on the front of the mounting frame.

[0007] Furthermore, the control structure includes a mounting platform fixedly installed on the left side of the mounting frame, a threaded rod with one end penetrating and extending to the outside of the mounting frame is rotatably installed inside the mounting frame, a connecting block is threadedly installed on the outer surface of the threaded rod, and an asynchronous motor fixedly connected to one end of the threaded rod is fixedly installed on the mounting platform.

[0008] Furthermore, the metal screen is fixedly installed inside the screening machine, a vibration motor is installed at the bottom of the metal screen, and the support bracket is fixedly installed on the front and back of the screening machine.

[0009] Furthermore, the connecting bracket includes an L-shaped connecting plate and a connecting frame, the L-shaped connecting plate and the connecting frame are welded together, the back of the L-shaped connecting plate is fixedly connected to the front of the connecting block, and the connecting frame is fixedly connected to the cleaning plate.

[0010] Furthermore, the guiding component includes a guide rod, which is fixedly installed between the left and right side walls of the inner cavity of the mounting frame. A connecting hole is provided inside the connecting block, and one end of the guide rod passes through the connecting hole and is slidably connected to the inner wall of the connecting hole.

[0011] Furthermore, each of the two limiting plates includes a mounting plate and a pressure sensor. The two pressure sensors are respectively fixedly mounted on opposite sides of the two mounting plates. The two pressure sensors are respectively electrically connected to the asynchronous motor. The two mounting plates are fixedly mounted on the front of the mounting frame.

[0012] Furthermore, a circular groove is provided on the left side of the mounting frame, and a bearing is fixedly installed inside the circular groove. One end of the threaded rod passes through the bearing and is fixedly connected to the output shaft of the asynchronous motor. The inner circumferential wall of the bearing is fixedly connected to the outer surface of the threaded rod.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This interception device for water conservancy construction, through the inclusion of a cleaning structure and a control structure, utilizes an asynchronous motor as a drive source to rotate a threaded rod. This causes the connecting block, connected by threads on the outer surface of the threaded rod, to move a connecting bracket to the right. The moving connecting bracket then moves the cleaning plate synchronously, pushing away large pieces of sand and gravel from the metal screen. The moving connecting bracket then presses against a pressure sensor in a limiting plate, triggering the asynchronous motor to drive the threaded rod to rotate in the opposite direction. This, in turn, controls the connecting block and the cleaning plate to move back to their initial positions for the next cleaning operation. This reduces the labor intensity of workers, further improves the efficiency of sand and gravel screening, and enhances the practicality of the interception device for water conservancy construction.

[0019] 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.

[0020] Please see Figures 1 to 3 In this embodiment, a diversion device for water conservancy construction includes a screening machine 1. The screening machine 1 has a metal screen 2 inside and a support bracket 3 outside. The top of the screening machine 1 has a cleaning structure and a control structure. The metal screen 2 is fixedly installed inside the screening machine 1. A vibration motor is installed at the bottom of the metal screen 2. The support bracket 3 is fixedly installed on the front and back of the screening machine 1.

[0021] In this embodiment, the cleaning structure includes a mounting frame 41 fixedly installed on the top of the screening machine 1. A connecting block 42 is slidably installed inside the mounting frame 41. A connecting bracket 43 is fixedly installed on the front of the connecting block 42, extending through and into the interior of the screening machine 1. A cleaning plate 44 for cleaning large pieces of sand and gravel is fixedly installed on the connecting bracket 43, located on top of the metal screen 2. The connecting bracket 43 includes an L-shaped connecting plate and a connecting frame. The L-shaped connecting plate and the connecting frame are welded together. The back of the L-shaped connecting plate is fixedly connected to the front of the connecting block 42. The connecting frame is fixedly connected to the cleaning plate 44, facilitating the replacement of the cleaning plate 44 that has worn out due to long-term use. A guide component 45 is provided inside the mounting frame 41 to limit the movement trajectory of the connecting block 42. Two limiting plates 46 are fixedly installed on the front of the mounting frame 41 to limit the left and right movement range of the connecting bracket 43.

[0022] The guide component 45 includes a guide rod, which is fixedly installed between the left and right side walls of the inner cavity of the mounting frame 41. The connecting block 42 has a connecting hole inside, and one end of the guide rod passes through the connecting hole and is slidably connected to the inner wall of the connecting hole, thereby restricting the connecting block 42 to move left and right only on the outer surface of the guide rod.

[0023] By adopting the above technical solution, the connecting block 42 is controlled by the control structure to move the connecting bracket 43 to the right, thereby the connecting bracket 43 drives the cleaning plate 44 to move synchronously, and the cleaning plate 44 cleans the large pieces of sand and gravel on the metal screen 2 until the moving connecting bracket 43 squeezes the pressure sensor in the right limit plate 46, thereby triggering the control structure to control the cleaning plate 44 to return to the initial position.

[0024] In this embodiment, the control structure includes a mounting platform 47 fixedly installed on the left side of the mounting frame 41. A threaded rod 48 with one end penetrating and extending to the outside is rotatably installed inside the mounting frame 41. A connecting block 42 is threaded onto the outer surface of the threaded rod 48, so that rotating the threaded rod 48 can control the left and right movement of the connecting block 42. A circular groove is opened on the left side of the mounting frame 41, and a bearing is fixedly installed inside the circular groove. One end of the threaded rod 48 passes through the bearing and is fixedly connected to the output shaft of the asynchronous motor 49. The inner circumferential wall of the bearing is fixedly connected to the outer surface of the threaded rod 48, so as to facilitate the rotation of the threaded rod 48 by using the bearing. An asynchronous motor 49 fixedly connected to one end of the threaded rod 48 is fixedly installed on the mounting platform 47.

[0025] Each of the two limiting plates 46 includes a mounting plate and a pressure sensor. The two pressure sensors are fixedly mounted on opposite sides of the two mounting plates and are electrically connected to the asynchronous motor 49. The two mounting plates are fixedly mounted on the front of the mounting frame 41. The movable connecting bracket 43 presses the pressure sensor in the right limiting plate 46, thereby triggering the asynchronous motor 49 to drive the threaded rod 48 to rotate in the opposite direction and the connecting bracket 43 to press the pressure sensor in the left limiting plate 46, thereby triggering the asynchronous motor 49 to shut down.

[0026] By adopting the above technical solution, the asynchronous motor 49 on the mounting platform 47 is started, so that the asynchronous motor 49 drives the output shaft to rotate, and the rotating output shaft drives the threaded rod 48 to rotate synchronously, thereby controlling the connecting block 42 threaded on the outer surface of the threaded rod 48 to drive the connecting bracket 43 to move to the right.

[0027] The working principle of the above embodiments is as follows:

[0028] The interception device used in water conservancy construction operates by activating the asynchronous motor 49 on the mounting platform 47. This drives the output shaft to rotate, causing the threaded rod 48 to rotate synchronously. This, in turn, controls the connecting block 42, which is threaded onto the outer surface of the threaded rod 48, to move the connecting bracket 43 to the right. The connecting bracket 43 then moves the cleaning plate 44 synchronously, cleaning large pieces of sand and gravel from the metal screen 2. This continues until the moving connecting bracket 43 presses against the pressure sensor in the right limit plate 46, triggering the asynchronous motor 49 to drive the threaded rod 48 to rotate in the opposite direction. This, in turn, controls the connecting block 42 and the connecting bracket 43 to move to the left until the connecting bracket 43 presses against the pressure sensor in the left limit plate 46. This triggers the asynchronous motor 49 to shut down, restoring the cleaning plate 44 to its initial position.
