Description

Technical Field

[0001] The utility model relates to the technical field of gates, and more specifically, to a water conservancy opening and closing gate used in water conservancy project construction. Background Art

[0002] River gates, also known as sluices, are low-head hydraulic structures built on rivers and channels that use gates to control flow and regulate water levels. Closing the gates can block floods, tides, or raise upstream water levels. Opening the gates can discharge floodwaters, waterlogging, abandoned water, or wastewater, and can also supply water to downstream rivers. Sluices are widely used in small tributaries of some rivers. With the increasing amount of domestic garbage, garbage will float on most river surfaces. As the gates are opened to release water, the floating garbage on the water will flow along the channels to the downstream rivers, thereby polluting the downstream rivers.

[0003] Patent document CN218322637U discloses a water conservancy opening and closing gate for water conservancy project construction, relating to the technical field of water conservancy engineering. The gate comprises a base plate, above which is disposed a lifting mechanism comprising a first U-shaped plate and a gate body. The first U-shaped plate has two first chutes defined within it, and rectangular slides are fixedly connected to the sides of the gate body. The two rectangular slides are slidably connected within the two first chutes. A cleaning mechanism is disposed on the outer surface of the first U-shaped plate, comprising two first rectangular plates. The cleaning mechanism automatically captures and cleans garbage accumulated at the gate body, thereby preventing this garbage from flowing into the downstream river channel and causing pollution. Compared to manually capturing and cleaning garbage accumulated at the gate, the cleaning mechanism not only saves time and effort but also significantly reduces safety hazards. However, the filter holes of the prior art filter plates are easily clogged with garbage. The clogged filter holes affect the drainage efficiency of the filter plates, thus affecting their repeated use. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment:

[0026] like Figure 1-5 As shown, a water conservancy opening and closing gate for water conservancy project construction includes a gate frame 1, which is arranged in a channel, and a gate 2 is slidably arranged in the gate frame 1. A first driving mechanism 3 is arranged between the gate 2 and the gate frame 1, and the first driving mechanism 3 is used to drive the lifting of the gate 2 to realize the opening and closing of the gate 2; a collecting frame 4 is arranged on the water-facing side of the gate 2 in the gate frame 1, and the collecting frame 4 is used to collect garbage floating on the water surface on the water-facing side of the gate 2. A second driving mechanism 5 is arranged between the collecting frame 4 and the gate frame 1, and the second driving mechanism 5 is used to drive the lifting of the collecting frame 4; the collecting frame 4 includes two filter plates 41 arranged in an inverted V shape, and the two filter plates 41 are fixedly connected to two side plates 42 along the water-facing side. The ends of the two filter plates 41 away from each other are rotatably connected to the frame door 43. During the rising process of the collecting frame 4, the frame door 43 always fits in the water. On the inner side of the gate frame 1, until the rotating connection between the frame door 43 and the filter plate 41 moves to the top of the gate frame 1, the collecting frame 4 is driven by the second driving mechanism 5 to rise, and the garbage floating on the water-facing side of the gate 2 is collected, and the water mixed with the garbage is discharged from the filter holes on the filter plate 41. During the rising process, due to the inclined arrangement of the two filter plates 41, part of the garbage slides to both sides along the inclined surface, which is convenient for the staff to clean. When the collecting frame 4 rises to above the gate frame 1, due to the push of the garbage, the frame door 43 rotates away from the filter plate 41 and is placed on the gate frame 1, forming a slope, which helps the staff to clean out the garbage in the collection frame 4, and the slope formed by the frame door 43 rolls down; a cleaning mechanism 6 is provided below the collecting frame 4, and the cleaning mechanism 6 slides below the collecting frame 4 and rises and falls with the collection frame 4. The cleaning mechanism 6 is used to dredge the filter holes of the filter plate 41.

[0027] like Figure 1-5As shown, the cleaning mechanism 6 includes a movable frame 61 arranged below the collecting frame 4, and a plurality of second connecting rods 62 are fixedly connected to the upper end face of the movable frame 61. In this embodiment, four second connecting rods 62 are provided and the second connecting rods 62 are located at the four corners of the movable frame 61. The second connecting rod 62 passes through and slides on the side plate 42. A hand rod 63 is fixedly connected between two adjacent second connecting rods 62. The hand rod 63 is used by the staff to pull the movable frame 61 upward. A dredging rod 64 that is adapted to the filter holes on the filter plate 41 is fixedly connected to the movable frame 61, and a limiting ring 65 is fixedly connected to the rod body of the second connecting rod 62. The diameter of the limiting ring 65 is larger than the diameter of the second connecting rod 62. When the lower end face of the limiting ring 65 is in contact with the side plate 42, the dredging rod 64 does not contact the side plate 42. When the filter box 4 is lifted up, the limit ring 65 is pressed against the side plate 42 under the action of gravity, so that the movable frame 61 is away from the filter plate 41 and the dredging rod 64 does not contact the filter plate 41, so that the water in the collecting frame 4 can be discharged through the filter holes on the filter plate 41. In addition, the free ends of the dredging rods 64 are at the same distance from the filter plates 41 in the vertical direction. The free ends of the dredging rods 64 are provided with inclined surfaces, and the inclination of the inclined surfaces is the same as the inclination of the filter plates 41. When the hand lever 63 is pulled, the movable frame 61 is in contact with the side plate 42, and the dredging rods 64 are inserted into the filter holes, and the inclined surfaces on the dredging rods 64 form a whole with the inclined surfaces of the filter plates 41, which does not affect the staff from cleaning the garbage stuck on the filter plates 41 with tools such as scrapers (shovels). Moreover, after the dredging rods 64 penetrate into the filter holes, the clogged garbage in the filter holes can be pushed out, and the filter holes of the filter plates 41 are dredged, thereby improving the drainage efficiency when the filter plates 41 are used next time.

[0028] like Figure 1-5 As shown, a water hole 44 is further provided on the side plate 42, and the water hole 44 is arranged at the lowest point of the inclined surface of the filter plate 41. By setting the water hole 44, when some filter holes on the filter plate 41 are blocked, the drainage efficiency of the collection frame 4 is improved, and the water hole 44 is arranged on the side close to the staff, even if the water hole 44 is blocked, it is convenient for the staff to use tools (such as a screwdriver) to clear it.

[0029] like Figure 1-5 As shown, the gate frame 1 is provided with slide grooves 7 on both sides of the gate 2, and the slide grooves 7 are opened in the vertical direction. Slide blocks 8 are fixedly connected to both sides of the gate 2, and the slide blocks 8 slide in the slide grooves 7 to restrict the gate 2 so that it can only slide in the vertical direction.

[0030] like Figure 1-5As shown, the first driving mechanism 3 includes a first rotating ring 31 that passes through and is rotatably connected to the gate frame 1. A first threaded rod 32 is internally threadedly connected to the first rotating ring 31. The lower end of the first threaded rod 32 is fixedly connected to the gate 2. A first handwheel 33 is fixedly connected to the first rotating ring 31. By rotating the first handwheel 33, the first rotating ring 31 rotates on the gate frame 1, and the first threaded rod 32 drives the gate frame 1 to rise and fall, thereby achieving the raising and lowering of the gate 2.

[0031] like Figure 1-5 As shown, the second driving mechanism 5 includes a second rotating ring 51 that passes through and is rotatably connected to the gate frame 1. The second rotating ring 51 is internally threaded with a second threaded rod 52. The lower end of the second threaded rod 52 is fixedly connected to a connecting frame 53. A second hand wheel 54 is fixedly connected to the second rotating ring 51. A plurality of first connecting rods 55 are passed through and fixedly connected to the connecting frame 53. The upper ends of the first connecting rods 55 pass through and slide on the gate frame 1, and the lower ends of the first connecting rods 55 are fixedly connected to the side plates 42. By rotating the second hand wheel 54, the second rotating ring 51 is rotated on the gate frame 1. Under the cooperation restriction of the first connecting rods 55 and the gate frame 1, the second threaded rods 52 can drive the connecting frame 53 and the first connecting rods 55 to rise and fall, thereby causing the collection frame 4 to rise and fall.

[0032] The working principle of a water conservancy opening and closing gate used in a water conservancy project construction in this embodiment is as follows: when there is too much floating garbage on the water surface on the water-facing side of the gate 2, the staff rotates the second hand wheel 54 to make the collection frame 4 rise. During the rising process, the lower end surface of the limit ring 65 is in contact with the side plate 42, so that the cleaning mechanism 6 is also pulled and rises at the same time. During the rising process of the collection frame 4, the floating garbage on the water surface is collected. When the collection frame 4 rises above the water surface, due to the push of the garbage, the frame door 43 rotates away from the filter plate 41 and rests on the gate frame 1, forming a slope, which is helpful for the staff to collect the garbage. The garbage in the frame 4 is cleaned out and rolls down the slope formed by the frame door 43. If the filter holes on the filter plate 41 are blocked, the dredging rod 64 is inserted into the filter holes by pulling the hand lever 63 upwards to push out the blocked garbage in the filter holes and dredge the filter holes of the filter plate 41. Maintaining this height, another staff member uses a scraper or other tool to clean the garbage pushed out on the surface of the filter plate 41 to improve the drainage efficiency when the filter plate 41 is used next time; after cleaning, the hand lever 63 is lowered to lower the cleaning mechanism 6, and the collection frame 4 is lowered below the water surface again by turning the second hand wheel 54.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
