Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a flow regulation structure for a reservoir side channel spillway. Background Technology

[0002] Side-channel spillways are crucial flood discharge structures in water conservancy projects such as reservoirs and dams, and their flow regulation capacity directly affects the safety and operational efficiency of the entire system. Flow regulation is usually achieved by opening and closing gates mounted on fixed seats. The gates slide within pre-set guide channels on both sides via rollers or sliders to complete the lifting and lowering motion.

[0003] However, in actual operation, especially in rivers with a lot of silt and floating debris, the gate's guide channel is easily invaded and accumulated by silt, aquatic plants and other debris. Utility Model Content

[0004] The purpose of this invention is to provide a flow regulation structure for a reservoir side channel spillway to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reservoir side channel spillway flow regulation structure, including a fixed base, and further including: a spillway body fixedly connected to one end of the fixed base; a support plate is fixedly connected to the inner wall of the fixed base;

[0006] A cleaning component is mounted on a fixed base and corresponds to the gate's running trajectory. The cleaning component includes an arc-shaped baffle mounted on the surface of the fixed base. Both ends of the arc-shaped baffle are provided with receiving cavities, and a cleaning component is disposed inside the receiving cavity.

[0007] Preferably, the cleaning assembly further includes a slide rod slidably connected to one end of the cleaning component, and a spring is sleeved on the surface of the slide rod.

[0008] Preferably, the cleaning component is movably disposed within the receiving cavity and connected to the spring.

[0009] Preferably, the surface of the fixed base is provided with a guide groove, and a tapered guide plate is fixedly connected to the end of the guide groove, the working surface of which is an inclined surface.

[0010] Preferably, guide rollers are rotatably connected to both sides of the arc-shaped baffle, and the guide rollers are in rolling cooperation with the guide groove.

[0011] Preferably, the cleaning component is a scraper, the scraping edge of which matches the surface shape of the guide groove.

[0012] Preferably, when the arc-shaped baffle moves to the adjacent conical guide plate, the cleaning component is compressed and contracts, guiding the scraped material to the surface of the fixing seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By integrating cleaning components on the arc-shaped baffle, each opening and closing operation of the gate is equivalent to a comprehensive cleaning of the guide channel, fundamentally preventing the gate jamming problem caused by the accumulation of debris; the innovative linkage design of the scraper and the conical guide plate allows the scraper to be compressed and contracted at the end of its stroke, thereby smoothly guiding the scraped debris to the surface of the fixed seat and naturally flushing it away with the help of water flow, realizing full automation and no residue.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, a reservoir side channel type spillway flow regulation structure includes a fixed base 1, and also includes: a spillway body 2 fixedly connected to one end of the fixed base 1; a support plate 4 fixedly connected to the inner wall of the fixed base 1; and a cleaning component 3, which is set on the fixed base 1 and corresponds to the gate running trajectory. The cleaning component 3 includes an arc-shaped baffle 301 set on the surface of the fixed base 1, and two ends of the arc-shaped baffle 301 are provided with receiving cavities 308. A cleaning component 303 is set inside the receiving cavity 308.

[0021] The structure includes a fixed base 1, and a spillway body 2 is fixedly connected to the right end of the fixed base 1, together forming a discharge channel. A support plate 4 is fixedly connected to the inner wall of the fixed base 1 to enhance the overall structural strength. A cleaning assembly 3 is installed on the fixed base 1, the position of which precisely corresponds to the operating trajectory of the gate. This cleaning assembly 3 includes an arc-shaped baffle 301 that serves as the gate carrier, and the arc-shaped baffle 301 moves on the fixed base 1 via structures on both sides. A receiving cavity 308 is opened at each end of the arc-shaped baffle 301, and a movable cleaning component 303 is installed inside each receiving cavity 308.

[0022] The cleaning assembly 3 also includes a slide bar 304 slidably connected to one end of the cleaning component 303, and a spring 305 is sleeved on the surface of the slide bar 304.

[0023] For each cleaning component 303, a slide rod 304 is slidably connected to its side away from the working end. A spring 305 is fitted on the surface of the slide rod 304, which is an elastic element that provides continuous clamping force.

[0024] The cleaning component 303 is movably disposed within the receiving cavity 308 and is connected to the spring 305.

[0025] The cavities 308 formed at both ends of the arc-shaped baffle 301 provide installation and movement space for the cleaning component 303 and the spring 305. The cleaning component 303 is configured to slide back and forth within the cavities 308. Meanwhile, one end of the spring 305 acts directly or indirectly on the cleaning component 303, while the other end abuts against the inner wall of the cavities 308, thus ensuring that the cleaning component 303 is always subjected to an outward thrust.

[0026] The surface of the fixed base 1 is provided with a guide groove 307, and a tapered guide plate 306 is fixedly connected to the end of the guide groove 307, the working surface of which is an inclined surface.

[0027] On the surfaces corresponding to both sides of the fixed base 1 and the arc-shaped baffle 301, a guide groove 307 is provided, which provides precise guidance for the movement of the arc-shaped baffle 301. At the end of each guide groove 307, a tapered guide plate 306 is fixedly connected. The working surface of the tapered guide plate 306 is designed as an inclined plane, which serves to guide the cleaning component 303 to retract and change the direction of movement of the scraped material.

[0028] Guide rollers 302 are rotatably connected to both sides of the arc-shaped baffle 301, and the guide rollers 302 are in rolling cooperation with the guide groove 307.

[0029] On both sides of the arc-shaped baffle 301, two guide rollers 302 are rotatably connected. These guide rollers 302 are precisely embedded and roll within the guide grooves 307 of the fixed seat 1, thereby converting sliding friction into rolling friction, greatly reducing the resistance of the arc-shaped baffle 301 during movement, and reducing wear.

[0030] The cleaning component 303 is a scraper, whose scraping edge matches the surface shape of the guide groove 307.

[0031] The cleaning component 303 is preferably in the form of a scraper. Its scraping edge is specially designed to closely match the shape of the contact surface of the guide groove 307. For example, if the surface of the guide groove 307 is flat, the scraper edge is straight; if the surface of the guide groove 307 is curved, the scraper edge is correspondingly curved to ensure maximum contact area and optimal scraping effect.

[0032] When the arc-shaped baffle 301 moves to the adjacent conical guide plate 306, the cleaning component 303 is squeezed and contracted, and the scraped material is guided to the surface of the fixed seat 1.

[0033] When the arc-shaped baffle 301 moves along the guide groove 307 to the conical guide plate 306 near the end, the cleaning component 303 (i.e., the scraper) will first contact the inclined surface of the conical guide plate 306. Under the squeezing action of the inclined surface, the cleaning component 303 overcomes the elastic force of the spring 305 and is forced to contract into the receiving cavity 308. During this contraction process, the mud, sand, and aquatic plants scraped away from the guide groove 307 by the scraper lose the obstruction of the scraper and will be naturally guided and discharged from the guide groove 307 along the inclined surface of the conical guide plate 306, falling onto the wide surface of the fixed base 1, and then being washed away by the flowing water, thus completing the automatic and continuous sludge removal process.

[0034] Working principle: When the gate (arc-shaped baffle 301) moves up and down along the guide groove 307 under the action of the drive device, the pre-tensioned spring 305 continuously pushes the cleaning component 303 (scraper) through the slide rod 304, so that its scraping edge is always pressed tightly against the working surface of the guide groove 307 to roll or slide. During this process, mud, sand, weeds and other debris attached to or falling into the guide groove 307 are scraped off in real time. When the gate moves to the end of the guide groove 307 and is about to reach the fully open or fully closed position, the cleaning component 303 first contacts and climbs up the inclined surface of the conical guide plate 306 fixed at the end of the guide groove 307. The inclined surface of the conical guide plate 306 generates a huge compressive force, forcing the cleaning component 303 to overcome the elastic force of the spring 305 and retract smoothly into the receiving cavity 308. As the cleaning component 303 retracts, the debris scraped between it and the working surface of the guide channel 307 is no longer obstructed. Guided by the inclined surface of the conical guide plate 306, it is naturally pushed out of the guide channel 307 and falls onto the wide surface of the fixed seat 1. At this time, the water flowing through the spillway body 2 will easily wash away the debris that has gathered on the surface of the fixed seat 1, thus completing a complete cleaning cycle.
