Description

Technical Field

[0001] This utility model relates to a water diversion guide gate for water conservancy and hydropower facilities, belonging to the technical field of water conservancy facilities. Background Technology

[0002] Water diversion guide gates are key control devices installed at the inlets of channels, tunnels, or pipelines in water conservancy and hydropower projects. They are mainly used to regulate the flow rate entering the water diversion system and guide the water flow. The gates are raised, lowered, or rotated by a hoist to precisely control the water level and flow velocity, while a special guiding structure ensures the water flows smoothly into the water conveyance structures.

[0003] Utility model patent CN219011124U discloses a hydraulic gate capable of intercepting garbage. This device, through an interception mechanism, allows water to flow out through holes in a rotating plate when the gate is opened. When garbage is present in the water, it is caught and fixed by a conical rod during flow, thus adhering to the rotating plate. When too much garbage accumulates on the rotating plate, affecting normal water flow, the increased water pressure causes the rotating plate to tilt, allowing water to drain through the gap between two rotating plates before contacting the next set of plates. In this way, with multiple supports connected, water can pass through multiple sets of rotating plates, achieving step-by-step interception of garbage.

[0004] However, although the device can hook the garbage passing through the canal with a conical rod, the garbage is difficult to remove and clean because the conical rod is located inside the support. Utility Model Content

[0032] This utility model embodiment provides a water diversion guide gate for water conservancy and hydropower facilities, such as... Figures 1 to 4 As shown, the water diversion guide gate includes:

[0033] The gate body 102 is installed in the water channel 1;

[0034] The interception mechanism 2 includes supports 201 arranged on both sides of the water channel 1, a drive unit arranged on the supports 201, and a filter cylinder 204 arranged in the water channel 1. The filter cylinder 204 has end plates 203 at both ends for closing its ports. A support shaft is arranged at the center of the end plate 203. The filter cylinder 204 is mounted on the supports 201 through the support shaft on the end plate 203. The drive unit is connected to the support shaft and is used to drive the support shaft to rotate, thereby driving the filter cylinder 204 to rotate.

[0035] The outer surface of the filter cartridge 204 is provided with multiple mounting grooves 205, which are arranged around the central axis of the filter cartridge 204. Each mounting groove 205 is provided with a mounting plate 207, and the surface of the mounting plate 207 is provided with multiple hooks 210, which are arranged along the length of the mounting plate 207.

[0036] A collection mechanism is installed in the water channel 1 and located on one side of the filter cylinder 204, for collecting garbage that falls from the hook 210 during the rotation of the filter cylinder 204.

[0037] In practical applications, each mounting slot 205 is equidistantly arranged around the central axis of the end plate 203, and each hook 210 is equidistantly arranged along the length of the mounting plate 207.

[0038] The aforementioned drive unit is a geared motor 202, which is mounted on the outer wall of the bracket 201. The output shaft of the geared motor 202 is connected to the support shaft of the end plate 203 via a coupling.

[0039] For example, the geared motor 202 can be a cycloidal pinwheel geared motor, with the power selected from 0.75kW to 3kW depending on the size of the drum. An overload protection switch can be installed to prevent foreign objects from getting stuck in the filter cartridge 204 and causing the motor to burn out.

[0040] refer to Figure 1 , Figure 3 and Figure 4 As shown, the mounting plate 207 is detachably connected to the end plate 203 of the filter cartridge 204.

[0041] Specifically, threaded holes 208 are provided at both ends of the mounting plate 207, and mounting holes 211 are provided on the inner walls of the two end plates 203 corresponding to the positions of the mounting plate 207. The threaded holes 208 and the corresponding mounting holes 211 are connected by bolts.

[0042] Furthermore, the mounting plate 207 has an external through hole 209 along its length, and the bottom wall of the mounting groove 205 has an internal through hole 206 along its length. The internal through hole 206 on the mounting groove 205 corresponds to the position of the external through hole 209 on the corresponding mounting plate 207.

[0043] This utility model has external through holes 209 through the upper and lower ends of each mounting plate 207, and internal through holes 206 through the upper and lower ends of the bottom wall of the corresponding mounting groove 205. The internal through holes 206 and external through holes 209 are aligned, which facilitates the flow of water in the water channel 1.

[0044] refer to Figure 1 and Figure 2 As shown, the collection agencies include:

[0045] A wedge-shaped strip 103 is set on one side of the filter cylinder 204, and its two ends are fixed on the two side walls 101 of the water channel 1. Multiple vertical grooves 105 are opened on the vertical surface of the wedge-shaped strip 103. The multiple vertical grooves 105 are arranged along the length direction of the wedge-shaped strip 103 and correspond one-to-one with multiple hooks 210 on each mounting plate 207.

[0046] The collection basket 106 is fixed on the two side walls 101 of the water channel 1 and is located below the wedge-shaped strip 103.

[0047] The collection basket 106 has multiple drainage holes 107 on its side wall. A filter plate 108 is provided on the bottom wall of the collection basket 106.

[0048] This invention features a row of vertical grooves 105 on a wedge-shaped bar 103. Hooks 210 rotate axially around the filter cylinder 204 and pass directly through the vertical grooves 105. Debris adhering to the surface of the hooks 210 is trapped on the surface of the wedge-shaped bar 103. The vertical grooves 105 act like filter holes on a filter screen, filtering the debris. Simultaneously, the vertical sides of the wedge-shaped bar 103 push away debris adhering to the surface of the filter cylinder 204 or mounting plate 207, while the hooks 210 place the trapped debris on the inclined surface of the wedge-shaped bar 103, facilitating its fall into the collection basket 106 below the wedge-shaped bar 103.

[0049] In practical applications, both ends of the wedge-shaped strip 103 are provided with first mounting ears 104, and the first mounting ears 104 are bolted to the side walls 101 of the water channel 1. The top of the side wall of the collection basket 106 near the side walls 101 of the water channel 1 is provided with second mounting ears 109, and the second mounting ears 109 are bolted to the side walls 101 of the water channel 1.

[0050] refer to Figures 1 to 4As shown, the water channel 1 includes a side wall 101. A gate body 102 is installed on the inner side of the side wall 101. An end plate 203 and a filter cylinder 204 are supported on the upper inner side of the side wall 101. A wedge-shaped strip 103 is fixed on the top of the side wall 101 near the filter cylinder 204. Both ends of the wedge-shaped strip 103 are fixedly connected to a first mounting ear 104. The first mounting ear 104 is fixedly connected to the side wall 101 by bolts. Several vertical grooves 105 are formed on the vertical surface of the wedge-shaped strip 103. Each vertical groove 105 is equidistant from the length of the wedge-shaped strip 103. The inner wall of the wedge-shaped strip 103 is respectively connected to each vertical groove 105. The hooks 210 are located on the same vertical plane. A collection basket 106 is provided below the wedge-shaped strip 103. The top two sides of the collection basket 106 are fixedly connected with second mounting ears 109. The second mounting ears 109 are fixedly connected to the top of the side wall 101 by bolts. A drainage hole 107 is opened through the vertical surface of the collection basket 106. A filter plate 108 is fixedly connected to the bottom surface of the collection basket 106. The vertical groove 105 and the bottom filter plate 108 facilitate the drainage of water accumulated in the collection basket 106, avoiding excessive water accumulation in the collection basket 106, which would cause garbage to float upward and overflow from the top of the collection basket 106.

[0051] The working principle of this utility model:

[0052] Water flows through the inner through-hole 206 and the outer through-hole 209 in the water channel 1, while garbage is trapped on the surface of the filter cylinder 204 or the mounting plate 207. When cleaning the garbage on the water surface, the reduction motor 202 is started to drive the end plate 203 and the filter cylinder 204 to rotate. The rotation speed is maintained at 5-10 revolutions per minute. During the rotation of the filter cylinder 204, the hooks 210 on the outer surface hook up the garbage on the water surface. As the hooks 210 move, they pass through each vertical groove 105. The vertical side of the wedge bar 103 pushes away the garbage attached to the surface of the filter cylinder 204 or the mounting plate 207. The hooks 210 place the hooked garbage above the inclined surface of the wedge bar 103. The garbage on the surface of the wedge bar 103 slides down the inclined surface into the collection basket 106 under the action of gravity.

[0053] When collecting garbage in the collection basket 106, the bolts connecting the second mounting ear 109 to the side wall 101 can be removed, and then the collection basket 106 can be removed separately and the garbage cleaned. When the mounting plate 207 needs to be inspected, after turning off the reduction motor 202, the bolts inside the disassembly mounting hole 211 can be loosened, and then the mounting plate 207 can be removed from the mounting groove 205 and replaced.

[0054] The above description is only a few embodiments of this utility model and is not intended to limit this utility model in any way. Although this utility model is disclosed above with preferred embodiments, it is not intended to limit this utility model. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this utility model using the disclosed technical content are equivalent to equivalent implementation cases and all fall within the scope of the technical solution.
