Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation channel technology, and in particular to an adjustable water diversion control gate device for water conservancy and irrigation channels. Background Technology

[0002] With the advancement of high-level farmland water conservancy infrastructure construction projects in my country, especially the increasing demand for irrigation in irrigation districts, efficient irrigation in these districts has brought enormous challenges. In farmland water conservancy construction, main canals are built to vigorously promote water-saving irrigation, and diversion gates are usually installed at the junctions of main and branch canals.

[0003] In existing technologies, there are dedicated water supply channels in farmland environments that can stably deliver water to various farmland areas, ensuring that crops can obtain the water they need at different growth stages and avoiding drought problems caused by uneven natural rainfall.

[0004] However, during the process of releasing water through the irrigation canal, due to the lack of an object to measure the distance between the gate and the canal, an excessively large gap between the gate openings may cause the water flow to be too strong. The strong water flow may erode the field ridges, causing them to collapse, and causing the water flow from adjacent plots to mix. At the same time, because the water flow is uncontrollable, it is impossible to detect in time that the farmland has been irrigated to the required level. Utility Model Content

[0026] Example 1

[0027] like Figure 1 - Figure 5As shown, this utility model provides a technical solution: an adjustable water diversion control gate device for irrigation channels, including an adjusting mechanism 1, an auxiliary mechanism 2 arranged inside the adjusting mechanism 1, the adjusting mechanism 1 including a channel body 11, a gate plate 12 arranged inside the channel body 11, the inner side of the channel body 11 contacting the outer side of the gate plate 12, a central column 13 arranged on the inner wall of the middle end of the gate plate 12, the inner wall of the middle end of the gate plate 12 being fixedly connected to the outer side of the central column 13, and a top end of the central column 13 being provided with... There is a finger rod 16, the top end of which is fixedly connected to the bottom end of the finger rod 16. A scale mark 18 is provided at the top end of the finger rod 16, and the top end of the finger rod 16 slides in correspondence with one side of the scale mark 18. A side plate 17 is provided on the outer side of the scale mark 18, and the outer side of the scale mark 18 is fixedly connected to the inner wall of the side plate 17. A floor plate 14 is provided at the bottom end of the side plate 17, and the bottom end of the side plate 17 is fixedly connected to the top side of the floor plate 14. A lead screw 15 is provided on the inner wall of the center column 13, and the inner wall of the center column 13 is connected to the lead screw 15. The outer side of the rod 15 is threaded. A horizontal plate 112 is provided on the outer side of the top end of the rod 15. The outer side of the top end of the rod 15 is rotatably connected to the inner wall of one end of the horizontal plate 112. A slide 111 is provided on the inner wall of the horizontal plate 112. The inner wall of the horizontal plate 112 is slidably connected to the outer side of the slide 111. An arc-shaped plate 110 is provided on the top end of the slide 111. The top end of the slide 111 is fixedly connected to the bottom side of the arc-shaped plate 110. A locking plate 113 is provided at the bottom end of the slide 111. The bottom end of the slide 111 is connected to... One end of the locking plate 113 is vertically snapped in place. A guide rod 114 is provided on the inner wall of the locking plate 113. The inner wall of the locking plate 113 and the outer side of the guide rod 114 are slidably connected through it. The top end of the guide rod 114 is fixedly connected to the bottom side of the horizontal plate 112. A spring 115 is provided on the inner wall of the horizontal plate 112. The inner wall of the horizontal plate 112 and the top end of the spring 115 are fixedly connected. The bottom end of the spring 115 is fixedly connected to the top side of one end of the locking plate 113. The bottom end of the floor 14 is fixedly connected to the top side of the channel body 11.

[0028] In this embodiment, when using this type of adjustable irrigation canal water diversion control gate device, firstly, a gate plate 12 is provided in the canal, and the two are connected in a tightly fitted manner. A center column 13 is fixedly connected to the inner wall of the middle end of the gate plate 12, and a screw rod 15 is designed on the inner wall of the center column 13. The center column 13 can move up and down under the helical engagement of the screw rod 15. A finger rod 16 is installed at the top of the center column 13, and a scale mark 18 is designed on the top of the finger rod 16 in the corresponding direction. Then, the handle 19 on the screw rod 15 is rotated, causing the center column 13 to move up and down. The position column 13 and the gate 12 are raised synchronously. During the raising process, the finger rod 16 will slide next to the scale mark 18. In this way, the distance between the gate 12 and the channel body 11 can be determined. For example, if the opening is 20 centimeters, then 8 cubic meters of fluid can pass through per hour. Based on the correspondence between the opening of the gate 12 and the flow rate, the amount of fluid passing through the channel can be accurately controlled to meet the water demand of different irrigation areas. At the same time, with the cooperation of the scale mark 18 and the finger rod 16, the real-time status of the gate 12 can be intuitively and conveniently grasped.

[0029] A horizontal plate 112 is designed on the outer side of the top of the lead screw 15. One end of the side of the horizontal plate 112 is fixed to the top side of the floor 14. The horizontal plate 112 restricts the lead screw 15 from the top, providing rotational support for the lead screw 15. A slide 111 is installed on the inner wall of the horizontal plate 112. The slide 111 can slide within the horizontal plate 112. At the same time, an arc-shaped plate 110 is fixed to the top of the slide 111. A recess is formed on the inner side of the arc-shaped plate 110. The locking plate 113 corresponds to the recessed part of the throttle 19 on the lead screw 15. During the alignment process, the locking plate 113 needs to be pulled down. After alignment, the external force of the locking plate 113 is released, so that the spring 115 uses its own retraction to reset the locking plate 113. At the same time, one end of the locking plate 113 is inserted into the slide block 111, so that the position after the arc plate 110 and the throttle 19 are engaged does not loosen, thus preventing the lead screw 15 from rotating due to shaking when the gate 12 is subjected to excessive water flow impact.

[0030] A guide rod 114 is installed on the inner wall of the locking plate 113. The outer side of the guide rod 114 penetrates the inner wall of the locking plate 113. The locking plate 113 is rectangular in shape. As a result, the path of the locking plate 113 will not deviate during the sliding process, ensuring that it can accurately enter the slide block 111.

[0031] Example 2

[0032] like Figure 2 - Figure 3 As shown, the auxiliary mechanism 2 includes a filter screen 21, a connecting rod 22 is provided on one side of the filter screen 21, one side of the filter screen 21 is fixedly connected to one end of the connecting rod 22, the other end of the connecting rod 22 is slotted and slidably connected to the inner wall of the gate plate 12, and the outer side of the filter screen 21 is fixedly connected to the inner side of the channel body 11.

[0033] In this embodiment, a filter screen 21 is installed on the inner side of the channel body 11, and a connecting rod 22 is installed on one side of the filter screen 21. One end of the connecting rod 22 is designed with a roller, and the end with the roller is located on the inner wall of the gate plate 12. Thus, during the lifting and lowering movement of the gate plate 12, the roller and the inner wall of the gate plate 12 can be rolled together to adjust the position of the connecting rod 22 and the filter screen 21 synchronously. This ensures that the filter screen 21 always fits against the inner side of the channel and maintains the corresponding position as the gate plate 12 rises and falls. This avoids jamming or friction interference between the gate plate 12 and the filter screen 21 when the gate plate 12 moves, and allows the filter screen 21 to continuously filter the fluid in the channel, preventing impurities from entering the downstream and affecting the irrigation equipment or blocking the water flow.

[0034] Working principle:

[0035] like Figure 1 - Figure 5 As shown, rotating the handle 19 on the lead screw 15 causes the center column 13 and the gate 12 to rise synchronously. During the lifting process, the finger rod 16 slides to the side of the scale mark 18. In this way, the distance between the gate 12 and the channel body 11 is determined. Based on the correspondence between the opening of the gate 12 and the flow rate, the flow rate of the fluid in the channel can be precisely controlled. The horizontal plate 112 restricts the flow from the top of the lead screw 15, providing rotational support for the lead screw 15. A slide 111 is installed on the inner wall of the horizontal plate 112, which can slide within the horizontal plate 112. An arc-shaped plate 110 is fixed at the top of 1. The inner side of the arc-shaped plate 110 has a recess that corresponds to the recess of the handle 19 on the screw 15. During the alignment process, the locking plate 113 needs to be pulled down. After alignment, the external force of the locking plate 113 is released, so that the spring 115 uses its own retraction to reset the locking plate 113. At the same time, one end of the locking plate 113 is inserted into the slide 111, so that the position of the arc-shaped plate 110 and the handle 19 after engagement is not loose. This prevents the screw 15 from rotating due to shaking when the gate 12 is subjected to excessive water flow impact, which would affect the distance between the gate 12 and the channel body 11.

[0036] By installing a filter screen 21 on the inner side of the channel body 11, and a connecting rod 22 on one side of the filter screen 21, with a roller at one end of the connecting rod 22, the connecting rod 22 and the filter screen 21 can be adjusted synchronously by the rolling contact between the roller and the inner wall of the gate 12 during the lifting and lowering movement of the gate 12, so that the filter screen 21 always fits the inner side of the channel and maintains the corresponding position with the lifting and lowering of the gate 12.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
