Description

Technical Field

[0001] This utility model relates to the technical field of diversion devices for water conservancy construction, specifically a diversion device for water conservancy construction. Background Technology

[0002] Water flow control during water conservancy construction is usually called construction diversion. It is to create the necessary construction conditions and meet the water use requirements of various departments as much as possible by safely diverting or impounding part or all of the water from the original river at various times in a predetermined manner, time and place. Diversion construction technology is a measure of water conservancy projects.

[0003] For example, a water conservancy construction diversion device with authorization announcement number "CN220868111U" solves the problem that existing water conservancy construction diversion devices are difficult to clean during backflow, and the filter equipment is prone to clogging. The aforementioned anti-backflow plate can effectively prevent water backflow and can also perform simple filtration of the water flow. In water conservancy construction, it prevents the filtered water from mixing with the unfiltered water due to backflow, reducing impurities in the water. Considering that the existing anti-backflow plate has a fixed orientation, the water flow direction is singular, and an external adapter is needed to control the direction, making it convenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing water diversion devices for water conservancy construction require external adapters to control the direction, which makes them inconvenient to use. Therefore, this invention proposes a water diversion device for water conservancy construction.

[0006] Preferably, the adjusting mechanism includes a round rod, the outer wall of which is fixedly connected to the filter box, the outer wall of which is rotatably connected to a cylinder, the outer wall of which is fixedly connected to a fixing plate, and the inner wall of which is rotatably connected to a connecting rod.

[0007] Preferably, the outer wall of the slider is slidably connected to the connecting rod, and the outer wall of the fixing plate is connected to a cleaning mechanism.

[0008] Preferably, the cleaning mechanism includes a first fixed frame, the outer wall of the first fixed frame is fixedly connected to a fixed plate, the inner wall of the first fixed frame is movably connected to a filter frame, the inner wall of the filter frame is movably connected to an inlet hard pipe, and the outer wall of the inlet hard pipe is movably connected to the first fixed frame.

[0009] Preferably, the inner wall of the water inlet rigid pipe is rotatably connected to the guide vane, and the outer wall of the first fixed frame is machined with through holes.

[0011] Preferably, the lower end of the fixing plate is fixedly connected to the second fixing frame.

[0012] The present invention proposes a flow guiding device for water conservancy construction, which has the following advantages: by driving the fixed plate to deflect at an arc angle through the end of the connecting rod, the lower end of the fixed plate will rest on the fixed rod on one side inside the filter box, so that the orientation of the fixed plate in the filter box is changed.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a diversion device for water conservancy construction includes a filter box 1 and a box cover 2. The filter box 1 is fixedly connected to the box cover 2 by bolts. A cover plate 3 is installed on the upper end of the box cover 2. The inner wall of the filter box 1 is fixedly connected to a rigid pipe 4. A water valve 5 is installed on the outer wall of the rigid pipe 4. The inner wall of the box cover 2 is slidably connected to a slider 7. An adjustment mechanism 6 is connected to the inner wall of the filter box 1.

[0023] The adjustment mechanism 6 includes a round rod 601, which is driven by a fixed plate 603 through a cylinder 602. The angle of the round rod 601 is adjusted so that the orientation of the fixed plate 603 is adjusted. The outer wall of the round rod 601 is fixedly connected to the filter box 1, the outer wall of the round rod 601 is rotatably connected to the cylinder 602, the outer wall of the cylinder 602 is fixedly connected to the fixed plate 603, and the inner wall of the fixed plate 603 is rotatably connected to the connecting rod 604.

[0024] The end of the connecting rod 603 drives the fixing plate 603 to deflect at an arc angle. The lower end of the fixing plate 603 will rest on the fixing rod 9 on one side inside the filter box 1, so that the orientation of the fixing plate 603 in the filter box 1 is changed. The end of the water inlet hard pipe 803 is inserted into the interior of the first fixing frame 801 and the filter frame 802. The water inlet valve 5 of the hard pipe 4 facing the same direction is turned to open it, so that the direction of water flow outward is directly changed, making it more convenient to use.

[0025] The outer wall of the slider 7 is slidably connected to the connecting rod 604. The outer wall of the fixed plate 603 is connected to the cleaning mechanism 8. The filter frame 802 can be directly pulled outward from the inside of the first fixed frame 801 to achieve the effect of cleaning the inside of the filter frame 802. The cleaning mechanism 8 includes the first fixed frame 801. The outer wall of the first fixed frame 801 is fixedly connected to the fixed plate 603. The inner wall of the first fixed frame 801 is movably connected to the filter frame 802. The filter frame 802 is made of stainless steel wire mesh woven into a rectangular filter frame shape, which mainly filters impurities in the incoming water. The inner wall of the filter frame 802 is movably connected to the inlet hard pipe 803. The outer wall of the inlet hard pipe 803 is movably connected to the first fixed frame 801.

[0026] Working principle:

[0027] Preparation stage

[0028] By fixing the rigid pipes 4 on both sides of the filter box 1 to the external water pipe, and manually pushing the connecting rod 603 to drive the slider 7 to slide left and right on the box cover 2, the end of the connecting rod 603 drives the fixing plate 603 to deflect in an arc angle, and the cylinder 602 at the lower end of the fixing plate 603 will rotate on the round rod 601. At the same time, when the fixing plate 603 deflects in an arc angle, the inner wall of the connecting rod 603 will move up and down on the slider 7 until the lower end of the fixing plate 603 rests on the fixing rod 9, so that the position of the fixing plate 603 is stabilized. Manually lift the cover plate 3 on the box cover 2, put the filter frame 802 into the first fixing frame 801, and continue to insert the end of the water inlet rigid pipe 803 into the first fixing frame 801 and the filter frame 802. The overall preparation stage is completed.

[0029] Use phase

[0030] Water is injected into the interior of the first fixed frame 801 and the filter frame 802 through the rigid pipe 4. At this time, the filter frame 802 filters the water, and the blocky impurities remain inside the filter frame 802. The water will flow outward from the multiple through holes 12 on the outer wall of the second fixed frame 10. Turn the water valve 5 on the right rigid pipe 4 to open it and let the water flow outward. Depending on the usage cycle and flow direction, the cover plate 3 on the overbox cover 2 can be lifted to remove and clean the filter frame 802 inside the first fixed frame 801. The filter frame 802 can be put into the interior of the second fixed frame 10 in the same way to control the flow direction and size of the water flow, thereby realizing the guidance of water flow in the water conservancy construction process.

[0031] Example 2:

[0032] Please see Figure 1-6 In this embodiment, the inner wall of the water inlet hard pipe 803 is rotatably connected to the guide vane 11, the outer wall of the first fixed frame 801 is machined with a through hole 12, the outer wall of the filter box 1 is fixedly connected to the fixed rod 9, the outer wall of the fixed rod 9 abuts against the fixed plate 603, and the lower end of the fixed plate 603 is fixedly connected to the second fixed frame 10.

[0033] The guide vanes 11 inside the inlet hard pipe 803 are rotated by the water, and the water forms a dispersed flow to alleviate the impact force. This prevents the water from flowing from the inlet hard pipe 803 into the filter frame 802 in a fixed direction. The water inside the filter frame 802 forms a tumbling effect, which increases the speed at which the water flows out of the filter frame 802.
