Description

A kind of roof rainwater collecting device

Technical field

The utility model relates to a kind of rainwater collection technique, is specifically related to a kind of device utilized by roof rainwater collection.

Background technology

Much area shortage of water resources is serious in current China, rainwater catchment system can partial rcsponse this kind of situation, and roofing runoff to compare other underlying runoff comparatively clean, be suitable for recycling. Rainfall Collection utilization technology is mostly realize by building large-scale rainwater collection and cleaning project in architectural application, and the amount of rainfall that rainwater catchment system engineering is collected is big, and water quality is better; But its shortcoming is: rainwater catchment system project occupation of land area is relatively big, structure and equipment are complicated, and cost is also higher.

China is populous, it it is the serious country of a shortage of water resources, a lot of areas underground water is on the verge of exhaustion because excessively gathering, and surface water body is seriously polluted again is difficult to utilization, if can be made full use of by rainwater, the nervous situation of water resources can be made to obtain partial rcsponse. But build that large-scale rainwater catchment system construction costs is high and floor space big, geologic condition is had certain requirement. If can small design and the collection container that comparatively clean rain water on roof can be carried out primary purifying, will more be conducive to universal in the whole nation of rainwater catchment system.

Summary of the invention

The purpose of this utility model is the defect existed to solve in prior art, it is provided that a kind of packaged unit that rain water on roof can carry out primary purifying.

In order to achieve the above object, the utility model provides a kind of roof rainwater collecting device, comprises dewatering horizontal tube, collection box and rising pipe; Collection box is connected with Drinage of house standpipe by dewatering horizontal tube; It is connected with dewatering horizontal tube above collection box left end, below left end, it is provided with sealed gate; Overflow weir vertically it is provided with in collection box; Collection box is interior, overflow weir right-hand member is provided with ball float switching arrangement; Being provided with water outlet below collection box right-hand member, this water outlet is connected with rising pipe.

Ball float switching arrangement comprises ball float, connecting rod and rubber ball-shaped plug; Ball float is connected with rubber ball-shaped plug by connecting rod; Connecting rod is fixed on the inwall of collection box by bearing; When collection box carries out Chu Shuishi, rubber ball-shaped plug is positioned at collection box, water outlet.

Connecting rod is Z font.

Above-mentioned ball float switching arrangement also comprises stay cord and pulley; Pulley rotates to be located on collection box; Stay cord is by pulley system on connecting rod, and one end stretches out outside collection box.

Case lid it is provided with above collection box.

In ramped shaped in collection box, bottom overflow weir left end, it is tilted to down along sealed gate.

Overflow weir is profile of tooth weir.

Collection box is rectangular parallelepiped, and internal capacity is 2 cubic metres.

The utility model has the following advantages compared to existing technology: the utility model utilizes overflow weir that collection box inside is divided into left and right two portions, left part casing is equivalent to a miniature settling tank, the solid particulate matter that roofing runoff is carried sinks under gravity and is separated with rainwater bottom left part casing, its underpart is provided with silt strobe emission, for discharging the silt of alluvial. Left part casing supernatant liquid flows into right portion casing by overflow weir, right portion casing is mainly used in storing the limpid rainwater by overflow weir, it is designed with ball float switching arrangement in right portion casing, prevent because the too high upset left part casing rainwater of liquid level in collection box carries particulate matter precipitation process in order to automatic regulating liquid surface height, make right portion casing rainwater keep limpid. The utility model volume is less, and structure is simple, and the rainwater of collection can be used in greening, flushes the toilet, and washes the lives such as car and uses mixedly, and can help the underground water saving part municipal water supply or preciousness on the ground of shortage of water resources.

Fig. 2 is the front shape schematic diagram of overflow weir in Fig. 1.

In figure, 1-dewatering horizontal tube, 2-sealed gate, 3-overflow weir, 4-ball float, 5-pulley, 6-stay cord, 7-bearing, 8-rubber ball-shaped plug, 9-collection box rising pipe, 10-connecting rod, 11-case lid, 12-Drinage of house standpipe.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, the utility model comprises dewatering horizontal tube, collection box rising pipe and collection box. Suitable at Drinage of house standpipe 12 highly connects dewatering horizontal tube 1, and the other end of dewatering horizontal tube 1 connects collection box. Collection box is rectangular parallelepiped, and useful volume about 2 cubic metres, its inside is provided with overflow weir 3, and box house is divided into left box body and right case. In ramped shaped bottom left end in collection box, it is tilted to down along left end, below collection box left end, it is provided with sealed gate 2. As shown in Figure 2, overflow weir 3 is profile of tooth weir. Rainfall early-stage rainwater carries the particulate matter of roofing accumulation, water quality is comparatively muddy, first this part roofing runoff enters the left box body of collection box, suspended particle in rainwater precipitates wherein, thereafter water level constantly raises, when left box body water level is elevated to a certain degree, the limpid rainwater on its upper strata just enters right case by overflow weir 3. When deposition accumulation is too much in left box body, sealed gate 2 can be opened and got rid of.

Right case is provided with ball float switching arrangement, and it is made up of ball float 4 and rubber ball-shaped plug 8, and as shown in Figure 1, ball float 4 is connected by connecting rod 10 with rubber ball-shaped plug 8. Connecting rod 10, in Z font, is inclined in right case, and upper flex point place is fixed on the right side of collection box on inwall by bearing 7, and upper end is connected with ball float 4, and lower end is connected with rubber ball-shaped plug 8. When right case water level is lower, ball plug 8 is pressed towards water outlet by connecting rod under ball float 4 action of gravity, prevents rainwater from flowing out; When collection box water level reach a certain height, ball float 4 drives ball plug 8 to move from water outlet by connecting rod 10 under buoyancy, and rainwater is discharged by rising pipe 9, so just can automatically regulate the water level in rainwater collection header. Being provided with the case lid 11 that can freely open above collection box, when not raining for slowing down, sun direct projection makes rainwater vaporization losses in collection box, and prevents external impurities from falling in casing. The upper right side of right case is provided with pulley 5, and stay cord 6 is tied up on connecting rod by pulley 5, as long as from collection box, water intaking pulls stay cord 6 to remove rubber ball-shaped plug 8 can to connect water from rising pipe 9 at ordinary times.
