Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy irrigation, in particular to a gate transmission device for water conservancy irrigation. Background Art

[0002] Irrigation refers to watering the land, mainly including methods such as sprinkler irrigation, drip irrigation, subsurface irrigation, and flood irrigation. Its irrigation principle is determined according to the water demand characteristics, growth stages, local climate, and soil environment of crops during their growth process. China is a large agricultural country. Affected by natural factors such as climate and geography, it is determined that China must follow the development path of irrigation agriculture. Currently, water conservancy irrigation agriculture adopts the method of diverting water from the main trunk canal to each farmland branch canal for irrigation.

[0003] Currently, in existing water conservancy irrigation, a gate plate and an installation groove are usually provided at the water inlet, and the gate plate is inserted into the installation groove to intercept the water flow. Since the installation groove is generally arranged at the bottom of the ditch, during actual use, the sediment at the bottom of the ditch will remain in the installation groove, reducing the sealing performance between the gate plate and the installation groove, resulting in a poor water flow interception effect. If the method of using the upstream water flow to impact the installation groove is adopted, it will cause excessive sediment accumulation and blockage in the downstream ditch, thus reducing the irrigation effect. Summary of the Utility Model

[0004] In view of the above problems, the present application provides a gate transmission device for water conservancy irrigation. By providing a sediment cleaning structure at the bottom of the installation groove, and using the downward movement of the gate plate to drive the sediment cleaning structure to clean the bottom of the installation groove and collect the sediment at the same time, the problem that the sealing performance between the existing gate plate and the installation groove is poor due to sediment residue, thus affecting the water flow control effect, is solved.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a gate transmission device for water conservancy irrigation, including a base and a pedestal fixedly arranged at the upper end of the base. An installation groove is opened on the pedestal, a sealing plate assembly is slidably installed in the installation groove, and a sediment cleaning assembly is arranged at the bottom of the installation groove. The upper end of the sediment cleaning assembly is hinged to the lower end of the sealing plate assembly.

[0006] The sediment cleaning assembly includes a rectangular sliding groove. The rectangular sliding groove is opened at the bottom of the installation groove, and both ends of the rectangular sliding groove penetrate to the side of the pedestal. Symmetrically arranged limiting sliding grooves are opened in the middle of the opposite side walls of the rectangular sliding groove. A sediment cleaning block is slidably installed at the bottom of the rectangular sliding groove. A limiting block is fixedly installed in the middle of the side wall of the sediment cleaning block close to the limiting sliding groove, and the limiting block is slidably installed in the limiting sliding groove. A connecting rod is hinged at a position close to the end of the upper end of the sediment cleaning block, and the upper end of the connecting rod is hinged to the lower end of the sealing plate assembly.

[0007] Preferably, the sealing plate assembly includes a "T"-shaped threaded rod, a sealing plate, a connecting spring, a cylindrical hole, a compression spring and a sliding column. A threaded hole is formed in the middle of the upper end of the base, and the "T"-shaped threaded rod is screwed into the threaded hole. Connecting springs are uniformly arranged at the top of the installation groove, and the lower end of the connecting spring is fixedly connected to the sealing plate. A cylindrical hole is formed in the middle of the lower end surface of the sealing plate, and the sliding column is slidably arranged in the cylindrical hole through the compression spring. The lower end of the sliding column is hinged to the upper end of the connecting rod.

[0008] Preferably, semi-cylindrical sliding grooves are symmetrically formed on the vertical side walls of the inner side of the installation groove, and the middle parts of both sides of the sealing plate are semi-cylindrical and are arranged in the semi-cylindrical sliding grooves in a matching manner.

[0009] Preferably, a wear-resistant protrusion is fixedly arranged in the middle of the upper end surface of the sealing plate, and the upper end of the wear-resistant protrusion abuts against the lower end of the "T"-shaped threaded rod.

[0010] Preferably, receiving grooves are symmetrically formed at positions on both sides of the cylindrical hole on the lower end surface of the sealing plate.

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the present utility model in combination with the drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts. It should be noted here that the descriptions of these embodiments are used to help understand the present utility model, but do not constitute a limitation to the present utility model.

[0028] As Figures 1-6 shown, a gate transmission device for water conservancy irrigation includes a base 1 and a base 2 fixedly arranged at the upper end of the base 1. An installation groove 3 is formed in the base 2. A sealing plate assembly 4 is slidably installed in the installation groove 3. A sediment cleaning assembly 5 is arranged at the bottom of the installation groove 3. The upper end of the sediment cleaning assembly 5 is hinged to the lower end of the sealing plate assembly 4.

[0029] On the positions of the two outer side walls of the base 2 close to the lower end, a sediment collector 21 is fixedly installed. The sediment collector 21 is hermetically connected to the end of the rectangular chute 51. The sediment collector 21 is a hollow cylindrical shape and its arc-shaped side wall is a porous mesh structure.

[0030] On the inner vertical side walls of the installation groove 3, semi-cylindrical chutes are symmetrically opened. The middle parts on both sides of the sealing plate 42 are semi-cylindrical and are arranged in the semi-cylindrical chutes in a matching manner.

[0031] The sealing plate assembly 4 includes a "T"-shaped threaded rod 41. A threaded hole is opened in the middle of the upper end of the base 2, and the "T"-shaped threaded rod 41 is screwed into the threaded hole. Connecting springs 43 are evenly arranged at the top of the installation groove 3. The lower ends of the connecting springs 43 are fixedly connected to a sealing plate 42. A wear-resistant protrusion 421 is fixedly arranged in the middle of the upper end surface of the sealing plate 42. The upper end of the wear-resistant protrusion 421 abuts against the lower end of the "T"-shaped threaded rod 41. A cylindrical hole 44 is opened in the middle of the lower end surface of the sealing plate 42. A sliding column 46 is slidably arranged in the cylindrical hole 44 through a compression spring 45. The lower end of the sliding column 46 is hinged to the upper end of a connecting rod 55. On the lower end surface of the sealing plate 42 and at the positions on both sides of the cylindrical hole 44, accommodation grooves 422 are symmetrically opened.

[0032] During specific operation, when it is necessary to intercept the water flow, the "T"-shaped threaded rod 41 is manually rotated to move downward while rotating. At this time, the connecting spring 43 is stretched. During the downward movement of the "T"-shaped threaded rod 41, it will continuously press the wear-resistant protrusion 421, thereby driving the sealing plate 42 and the sliding column 46 to move downward synchronously. Since, and the sliding column 46 will drive the sediment cleaning assembly 5 to move to both sides and clean the sediment at the bottom of the base 2. Due to the action of the compression spring 45, finally, the sliding column 46 will move into the cylindrical hole 44.

[0033] The sediment cleaning assembly 5 includes a rectangular chute 51. A rectangular chute 51 is opened at the bottom of the installation groove 3. Both ends of the rectangular chute 51 penetrate to the side of the base 2. Limiting chutes 52 are symmetrically opened in the middle of the opposite side walls of the rectangular chute 51. A sediment cleaning block 53 is slidably installed at the bottom of the rectangular chute 51. A limiting block 54 is fixedly installed in the middle of the side wall of the sediment cleaning block 53 close to the limiting chute 52. The limiting block 54 is slidably installed in the limiting chute 52. A connecting rod 55 is hinged at the position close to the end of the upper end of the sediment cleaning block 53. The upper end of the connecting rod 55 is hinged to the lower end of the sealing plate assembly 4.

[0034] During specific operation, when the sliding column 46 drives the connecting rod 55 to move downward, the sediment cleaning block 53 will slide along the rectangular chute 51 to both sides, so as to gather the sediment at the bottom of the base 2 to both ends of the rectangular chute 51. At the same time, due to the existence of the receiving groove 422, the connecting rod 55 will finally lie horizontally in the receiving groove 422, thus not affecting the sealing performance between the lower end of the sealing plate 42 and the bottom of the base 2. Finally, the sediment is pushed into the sediment collector 21 by the sediment cleaning block 53 for centralized collection.

[0035] Working principle: When it is necessary to intercept the water flow, manually rotate the "T"-shaped threaded rod 41 so that it rotates and moves downward at the same time. At this time, the connecting spring 43 is stretched. During the downward movement of the "T"-shaped threaded rod 41, it will continuously squeeze the wear-resistant protrusions 421, thereby driving the sealing plate 42 and the sliding column 46 to move downward synchronously. Since [reason not provided in the original], and the sliding column 46 will drive the connecting rod 55 to move downward;

[0036] During the process of the sliding column 46 driving the connecting rod 55 to move downward, the sediment cleaning block 53 will slide along the rectangular chute 51 to both sides, so as to gather the sediment at the bottom of the base 2 to both ends of the rectangular chute 51. At the same time, due to the existence of the receiving groove 422, the connecting rod 55 will finally lie horizontally in the receiving groove 422, thus not affecting the sealing performance between the lower end of the sealing plate 42 and the bottom of the base 2. Finally, the sediment is pushed into the sediment collector 21 by the sediment cleaning block 53 for centralized collection.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
