技术领域Technical Field
本实用新型涉及市政建设技术领域，特别涉及一种市政建设用雨水收集装置。The utility model relates to the technical field of municipal construction, in particular to a rainwater collection device for municipal construction.
背景技术Background Art
我国水资源紧缺，尤其是大部分以城市为中心的地区，全国700多个地级市以上的城市中，有近400座城市缺水或严重缺水，且成递增趋势，以致国家不得不花费巨资建设调水工程。雨水是自然界一种优质的淡水资源，经简单处理即可实现冲厕、路面喷洒、绿化浇灌的功能。但是雨水中常会含有大量的树叶和泥沙等杂质，雨水需要经过过滤才能投入使用。Water resources are in short supply in my country, especially in most urban areas. Among the more than 700 cities above the prefecture level in China, nearly 400 cities are short of water or seriously short of water, and the shortage is increasing, so the country has to spend a huge amount of money to build water diversion projects. Rainwater is a high-quality freshwater resource in nature. After simple treatment, it can be used for flushing toilets, spraying roads, and watering greenery. However, rainwater often contains a large amount of impurities such as leaves and sediment, so rainwater needs to be filtered before it can be put into use.
公开（公告）号：CN213062191U，公开了一种市政建设用雨水收集装置，通过设置涡轮、转轴和刮泥板，下雨天气时，雨水通过收集罩汇集到收集室的上方，雨水通过滤孔流进收集室内部，滤孔过滤掉了树叶和树枝等大型杂物，当收集室内部储存到一定量的水后，水压大于弹簧压力的时候，水的压力会将滑动挡水板向下压，当滑动挡水板离开挡水环内部时，大量的水流会向下流动，水流经过涡轮时，水的流动会带动涡轮旋转，由于涡轮和刮泥板是同轴设置，刮泥板会跟随涡轮一起旋转，此时刮泥板会将圆锥过滤板表面的泥沙刮掉，达到了刮泥板自动清理圆锥过滤板的效果，解决了雨水收集装置过滤板容易堵塞，不能自动清理的问题。Publication (Announcement) No.: CN213062191U discloses a rainwater collection device for municipal construction. By arranging a turbine, a rotating shaft and a scraper, when it rains, rainwater is collected to the top of the collection chamber through a collection cover, and the rainwater flows into the collection chamber through filter holes. The filter holes filter out large debris such as leaves and branches. When a certain amount of water is stored in the collection chamber and the water pressure is greater than the spring pressure, the water pressure will press the sliding water baffle downward. When the sliding water baffle leaves the inside of the water baffle ring, a large amount of water will flow downward. When the water flows through the turbine, the flow of water will drive the turbine to rotate. Since the turbine and the scraper are coaxially arranged, the scraper will rotate with the turbine. At this time, the scraper will scrape off the mud and sand on the surface of the conical filter plate, thereby achieving the effect of the scraper automatically cleaning the conical filter plate, and solving the problem that the filter plate of the rainwater collection device is easily blocked and cannot be automatically cleaned.
上述专利中，在雨水收集过滤过程中，通过刮泥板自动清理过滤板，但是清理的泥沙依旧在其内部，达不到很好的过滤效果，且拆装不便，实用性不高，因此，有必要提供一种市政建设用雨水收集装置。In the above patent, during the rainwater collection and filtration process, the filter plate is automatically cleaned by a scraper, but the cleaned mud and sand are still inside it, which cannot achieve a good filtration effect, and it is inconvenient to disassemble and assemble, and the practicality is not high. Therefore, it is necessary to provide a rainwater collection device for municipal construction.

The rotating ring block 501 is movably limited inside the rotating through groove 402 of the fixed block 401, the bottom of the sealing block 504 is in close contact with the threaded base 506, and the fixing bolt 505 is threadedly connected to the threaded base 506.
工作原理：首先通过将过滤单元400安装在固定杆503上后，通过手持手提环502，并将其插入中转壳201的内部，使第二过滤架405与第一过滤架403的外壁贴合中转壳201的内壁放入内部，当固定杆503底部的固定螺栓505接触到螺纹底座506后，通过转动手提环502，手提环502带动旋转环块501在固定块401的旋转通槽402的内部转动而带动固定杆503转动，固定杆503的转动通过密封块504带动固定螺栓505转动，使固定螺栓505螺纹拧进螺纹底座506的内部，直至完全拧紧，此时密封块504与螺纹底座506完全紧密连接，避免了雨水的侵蚀，该结构能够方便过滤单元400的整体拆装，拆装效率高，且省时省力易操作，便于后期过滤单元400的清洁和处理。Working principle: first, after the filter unit 400 is installed on the fixing rod 503, the hand ring 502 is held and inserted into the interior of the transfer shell 201, so that the outer wall of the second filter frame 405 and the outer wall of the first filter frame 403 are in contact with the inner wall of the transfer shell 201 and placed inside. When the fixing bolt 505 at the bottom of the fixing rod 503 contacts the threaded base 506, the hand ring 502 is rotated, and the hand ring 502 drives the rotating ring block 501 to rotate inside the rotating groove 402 of the fixing block 401, thereby driving the fixing rod 503 to rotate. The rotation of the fixing rod 503 drives the fixing bolt 505 to rotate through the sealing block 504, so that the fixing bolt 505 is threaded into the interior of the threaded base 506 until it is fully tightened. At this time, the sealing block 504 is completely and tightly connected with the threaded base 506 to avoid erosion by rainwater. This structure can facilitate the overall disassembly and assembly of the filter unit 400, has high disassembly and assembly efficiency, saves time and effort, and is easy to operate, which is convenient for the cleaning and treatment of the filter unit 400 in the later stage.
