Description
技术领域technical field
本实用新型属于市政排水设施,特别是涉及一种分流式屋面雨水自动弃流装置。The utility model belongs to municipal drainage facilities, in particular to a diversion type roof rainwater automatic discarding device.
背景技术Background technique
屋面雨水具有污染较少,水质稳定等优点,并且,随着城市化的不断加速,会建造更多的高楼大厦,因此,屋面雨水收集利用就成为城市节约水资源的有效措施。有研究表明,降雨开始后,屋面雨水形成径流,把空气中沉积在屋顶的颗粒污染物一起冲走,此时雨水径流污染较大,水质较差,而当降雨量达到2mm-3mm时,屋面雨水径流的水质就会有明显提高,并保持稳定。因此,在对屋面雨水进行收集时,将初期雨水弃流,然后收集后期雨水,即可达到较好的收集目的。目前,初期雨水弃流装置往往存在两个问题,一是尺寸规模较大,雨水弃流装置过大,若安放在地上会影响建筑的美观,若埋地不便于日后的检修及清理淤泥。如2009年9月23日公开的申请号为200820215494.5的实用新型专利,公开了一种初期雨水弃流装置,该装置包括弃流池、分水井和弃流器。使用时,雨水首先进入分水井初步过滤,然后通过弃流器流入弃流池里,当弃流池里水量达到初期雨水量时,弃流器关闭,中、后期雨水在分水井里改道流进储存池。由于该装置分水井、弃流池和储存池都分开建设,所以该装置占地面积大,埋地建设增加了土方开挖量,提高了工程费用。二是运行管理较为复杂,如使用电子设备控制闸阀启闭,在室外雨天时常会出现事故,造成设备失效,且不便于维修。如2010年11月17日公开的申请号为201010213032.1的发明专利,公开了一种立式屋面雨水自动初期弃流装置,该装置主要由整流板、分离室、弃流进水渠、弃流临时贮槽、弃流排水槽、浮球装置、电磁阀、液位传感器、电控箱、雨水收集管等组成。使用时,初期雨水流入弃流临时贮槽,到达预定水位时浮球将会封闭进水管进口,之后雨水全部进入收集管,与此同时,液位传感器根据设置的液位高度,将水位信号传送到电控箱,经过预先设定的时间间隔,电控箱向电磁阀发出信号,电磁阀开启将初期雨水排出。该装置使用了液位传感器、电控箱和电磁阀等电子设备,如不做保护措施,在雨天时设备易损坏失灵,当装置埋于地下时,由于电磁阀在装置的最底部,不易发现故障情况,且不便于维修。Roof rainwater has the advantages of less pollution and stable water quality, and with the continuous acceleration of urbanization, more high-rise buildings will be built. Therefore, the collection and utilization of roof rainwater has become an effective measure for urban water conservation. Studies have shown that after the rainfall begins, the roof rainwater forms runoff, which washes away the particulate pollutants deposited on the roof in the air. At this time, the rainwater runoff is more polluted and the water quality is poor. When the rainfall reaches 2mm-3mm, the roof The water quality of stormwater runoff will be significantly improved and remain stable. Therefore, when collecting roof rainwater, the initial rainwater is discarded, and then the later rainwater is collected to achieve a better collection purpose. At present, there are often two problems with the initial rainwater disposal device. One is that the size of the rainwater disposal device is too large. As the utility model patent published on September 23, 2009, the application number is 200820215494.5, which discloses a device for abandoning flow of initial rainwater, which device includes a flow abandoning pond, a diversion well and a flow abandoning device. When in use, the rainwater first enters the diversion well for preliminary filtration, and then flows into the diversion pool through the jet diverter. When the water volume in the diversion pool reaches the initial rainwater volume, the jet diverter is closed, and the rainwater in the middle and late stages diverts into the diversion well. storage pool. Because the water diversion well of the device, the jettison pond and the storage pond are all constructed separately, the device occupies a large area, and the buried construction increases the amount of earth excavation and increases the project cost. The second is that the operation management is relatively complicated. For example, if electronic equipment is used to control the opening and closing of the gate valve, accidents often occur in outdoor rainy days, resulting in equipment failure and inconvenient maintenance. For example, the invention patent with the application number 201010213032.1 published on November 17, 2010 discloses a vertical roof rainwater automatic initial discharge device, which is mainly composed of a rectifying plate, a separation chamber, a waste flow inlet channel, and a temporary storage of the waste flow. Tank, waste water drainage tank, floating ball device, solenoid valve, liquid level sensor, electric control box, rainwater collection pipe, etc. When in use, the initial rainwater flows into the temporary storage tank for the abandoned flow. When the predetermined water level is reached, the floating ball will close the inlet of the water inlet pipe, and then all the rainwater will enter the collection pipe. At the same time, the liquid level sensor will transmit the water level signal according to the set liquid level height. To the electric control box, after a preset time interval, the electric control box sends a signal to the solenoid valve, and the solenoid valve opens to discharge the initial rainwater. The device uses electronic equipment such as liquid level sensors, electric control boxes, and solenoid valves. If no protection measures are taken, the equipment will be easily damaged and malfunction in rainy days. When the device is buried underground, the solenoid valve is at the bottom of the device, so it is difficult to find fault condition and is not easy to repair.
