Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a reservoir channel gate for water conservancy projects. Background Art

[0002] In modern society, with the increase of national strength, the investment in water conservancy construction has become higher and higher. Not only large-scale water conservancy projects are continuously invested, but the country has also paid more and more attention to small-scale urban and rural water conservancy projects. With the continuous progress of water conservancy construction, the requirements for water conservancy facilities are also getting higher and higher. At present, most of the gates used in my country are lifting gates. This style of gate is easy to use, has good water storage capacity and high stability.

[0003] For example, the utility model with application number CN202320838422.0 discloses a channel gate for a reservoir used in a small water conservancy project. The utility model includes a base, and slide rails are fixedly connected to both sides of the top of the base, and a mounting plate is fixedly connected to one side of the slide rail. A bracket is fixedly connected between the tops of the two slide rails, and a slider is slidably connected to the inside of the slide rail. A door panel is fixedly connected between the sliders. A buffer mechanism is provided on the front and back of the door panel, and a fixing mechanism is provided on the top of the door panel. A motor is fixedly connected to the top of the bracket, and a screw rod is rotatably connected to the bottom end of the motor. However, during the use of the gate, due to the presence of aquatic plants such as water grass and water hyacinth in the canal, and sometimes a lot of floating garbage, and the gate is not easy to filter the water flow, when the gate is opened to discharge flood water, the water hyacinth or garbage will float away with the water flow and flow to the next water area. Once too much water hyacinth or garbage accumulates, it will destroy the ecology of the water area and affect the water quality.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a reservoir channel gate for water conservancy projects is proposed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reservoir channel gate for a water conservancy project, comprising a base, a main frame is fixed to the upper end of the base, and a winch mechanism is fixed to the top of the main frame, a sling is fixed to the output end of the winch mechanism, and a gate plate is fixed to the end of the sling away from the winch mechanism, guide slides are fixed to the left and right ends of the gate plate, a guide slide is fixed to the inner side wall of the main frame, a protruding bracket is fixed to the front end of the guide slide, a connecting plate is fixed to the front end of the bottom of the gate plate, a filter screen plate is fixed to the end of the connecting plate away from the gate plate, a guide slide groove is opened on the inner side wall of the protruding bracket, and a rear baffle is fixed to the rear of the filter screen plate at the rear end of the protruding bracket.

[0007] Furthermore, a fixing frame is fixed to the front end of the protruding bracket, and the fixing frame is symmetrically distributed about the center line of the protruding bracket.

[0008] Furthermore, a connecting shaft is rotatably connected between the two fixing frames, and a plurality of rotating disks are fixed on the outer surface of the connecting shaft.

[0009] Furthermore, the rotating disks are equidistantly distributed with respect to the surface connected to the rotating shaft.

[0010] Furthermore, blades are fixed on the surface of the rotating disk, and a cleaning brush is fixed on one end of the blade away from the rotating disk.

[0011] Furthermore, mounting seats are fixed on both left and right ends of the main frame.

[0012] The utility model provides a reservoir channel gate for water conservancy projects, which has the following beneficial effects:

[0013] 1. The utility model can utilize the hoisting mechanism to reel in the sling through the arrangement of the base, the main frame, the winch mechanism, the sling, the gate plate, the guide slide bar, the guide slide seat, the protruding bracket, the filter screen plate, the guide slide groove, the connecting plate and the rear baffle plate, so that the gate plate can be raised, and the filter screen plate fixedly connected to it can be raised together through the connecting plate, so that the filter screen plate can filter the water flow after the gate is opened. The structural design can increase the performance of the gate and prevent water hyacinths or garbage in the channel from floating away with the water flow when the gate is opened to release water, thereby affecting the ecology and water quality of the next water area.

[0014] 2. The utility model can utilize the kinetic energy generated by the impact of water flow on the blades to rotate the connecting shaft when the gate is opened to release flood water through the arrangement of the fixed frame, the connecting shaft, the turntable and the blades.

The filter screen plate 9 is a metal woven mesh. A guide slide groove 10 is opened on the inner side wall of the protruding bracket 8. Slide blocks are fixed to the left and right ends of the filter screen plate 9. The filter screen plate 9 is slidably connected to the guide slide groove 10 through the slide blocks. A rear baffle 12 is fixed to the rear of the filter screen plate 9 at the rear end of the protruding bracket 8, and the rear baffle 12 is fixedly connected to the base 1. The arrangement of the base 1, the main frame 2, the winch mechanism 3, the sling 4, the gate plate 5, the guide slide bar 6, the guide slide seat 7, the protruding bracket 8, the filter screen plate 9, the guide slide groove 10, the connecting plate 11 and the rear baffle 12 can increase the use function of the gate and filter the water flow.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a fixing frame 13 is fixed to the front end of the protruding bracket 8, and the fixing frames 13 are symmetrically distributed about the center line of the protruding bracket 8, a connecting shaft 14 is rotatably connected between the two fixing frames 13, and a plurality of turntables 15 are fixed to the outer surface of the connecting shaft 14, and the turntables 15 are equidistantly distributed about the surface of the connecting shaft 14, the number of the connecting shafts 14 is two, the number of the turntables 15 is six, and blades 16 are fixed to the surface of the turntable 15, and the blades 16 are equidistantly distributed in annular shapes about the center line of the turntable 15. The setting of the fixing frame 13, the connecting shaft 14, the turntable 15 and the blades 16 can consume a part of the impact force of the water flow to protect the gate, and a cleaning brush 17 is fixed to the end of the blade 16 away from the turntable 15, and the cleaning brush 17 is a brush made of hard bristle material to clean the surface of the filter screen plate 9, and mounting seats 18 are fixed to the left and right ends of the main frame 2.

[0024] Working principle: The water conservancy project uses reservoir channel gates. First, according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The structure shown in the figure needs to be installed before the gate is used. First, a groove is opened in the channel where the gate is to be installed, and the size matches the size of the rear baffle 12. Then, the structure composed of the protruding bracket 8 and the rear baffle 12 is embedded in the opened groove, and the protruding bracket 8 is not completely embedded in the groove. At this time, the base 1 will contact the bottom of the channel, and then the gate is installed and fixed in the reservoir channel by connecting the mounting seats 18 on both sides of the main frame 2 with the designated bolts. When it is necessary to open the gate to discharge flood, people can control the winch mechanism 3 on the top of the main frame 2 to start The sling 4 is moved to reel in the sling, so that the gate plate 5 fixedly connected to the sling 4 can be lifted up. At this time, the guide slides 6 at both ends of the gate plate 5 will slide upward on the guide slide seat 7 on the inner side wall of the main frame 2 to ensure the stability of the gate plate 5. As the gate plate 5 is lifted up, the filter screen plate 9 fixedly connected to the gate plate 5 through the connecting plate 11 will also be lifted up from the groove. At this time, the sliders at both ends of the filter screen plate 9 will slide in the guide slide grooves 10 provided on the inner side wall of the protruding bracket 8 to ensure the stability of the filter screen plate 9. When the gate plate 5 is lifted to a certain height, the filter screen plate 9 can slide in the guide slide grooves 10 provided on the inner side wall of the protruding bracket 8 to ensure the stability of the filter screen plate 9. When the filter screen plate 9 is lifted to the same height, the water in the channel will flow into the water area connected to the channel through the holes on the surface of the filter screen plate 9, and the filter screen plate 9 will prevent the water hyacinth or garbage in the channel from floating away with the water flow. In order to ensure the circulation of water, the water flow will impact the blades 16 on the multiple groups of turntables 15 arranged in front of the filter screen plate 9 during the flow, so that the blades 16 generate kinetic energy, which drives the connecting shaft 14 on the fixing frame 13 to rotate. As the blades 16 on the multiple turntables 15 fixedly connected to the filter screen plate 9 rotate, the blades 16 on the multiple turntables 15 fixedly connected to the filter screen plate 9 will also float away with the connecting shaft 14. The rotating shaft 14 rotates, and the cleaning brush 17 fixedly connected to the blade 16 will rotate with it, constantly contacting the surface of the filter screen plate 9, sweeping away the water hyacinth or garbage adhering to the filter screen plate 9, so as to avoid the surface of the filter screen plate 9 being completely covered by water hyacinth or garbage. When the gate is closed, the flow opening gradually becomes smaller, the water flow becomes faster, and the impact force generated will also become stronger. At this time, the blade 16 on the turntable 15 will continue to rotate under the impact of the water flow to consume part of the impact force of the water flow, thereby reducing the damage to the overall gate caused by the impact force of the water flow.
