Detailed Description

For the purpose of clearly illustrating the aspects of the present invention, preferred embodiments are given below in conjunction with the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

Referring to fig. 1, the rainwater storage tank with overflow structure of the present invention may include a rainwater storage tank (10), a rainwater inlet pipe (20), a water level alarm (30), an overflow structure and an adjusting tank (60). The overflow pipe (41) is connected with the rainwater inlet pipe (20), a first switch valve (42) is arranged on the overflow pipe (41), a second switch valve (43) is arranged on the rainwater inlet pipe (20), and rainwater flowing down from the roof can be branched into two paths at the connection part of the overflow pipe (41) and the rainwater inlet pipe (20). One path may pass through a first switching valve (42) and the other path may pass through a second switching valve (43), depending on the switching state of the switching valves. The on-off valve may be a control valve such as a solenoid valve.

As shown in the figure, at the initial stage of water storage, the second on-off valve (43) is in a normally open state, and the first on-off valve (42) is in a normally closed state. Therefore, rainwater on the roof flows downwards, passes through the second switch valve (43) arranged on the water inlet pipe (20) and then flows into the regulating tank (60), the regulating tank (60) can have functions of preliminary sedimentation, filtration, buffering and the like, and for example, the regulating tank (60) can be used as a rainwater initial-stage drainage device. For rainwater regulation pond (10), equalizing basin (60) set up higher position, and the rainwater through the equalizing basin flows into rainwater regulation pond (10) naturally.

When the water level in the rainwater storage tank (10) gradually rises and reaches the alarm water level, the water level alarm (30) arranged on the rainwater storage tank (10) gives an alarm or other signals, and when a control unit (not shown) receives the alarm or other electric signals, a control command is given, the second switch valve (43) is closed, and the first switch valve (42) is opened at the same time. Thus, rainwater on the roof flows into the overflow pipe (41) and is directly discharged to the outdoor through the first switch valve (42), thereby preventing adverse consequences caused by overflow of the rainwater storage tank (10). Those skilled in the art will appreciate that the control unit having the above capabilities can be easily implemented and will not be described in detail herein. Of course, the valve can be controlled manually, for example, when the water level alarm (30) is heard, the valve is manually opened and closed.

Fig. 2 is another embodiment of the present invention. As shown in the figure, unlike the embodiment shown in fig. 1, a drain pump (51) and a drain pipe (52) connected to the drain pump (51) are provided at the bottom of the rainwater storage tank (10). The drain pipe (52) extends to the outside of the rainwater storage tank (10), and water in the rainwater storage tank (10) can be drained to the outside under the driving of the drainage pump (51). The drain pump (51) may be, for example, a submersible pump.

In addition, an overflow port (53) is arranged at the upper part of the rainwater storage tank (10), and when the water level in the rainwater storage tank (10) is up to the position of the overflow port (53), the rainwater can naturally flow out of the rainwater storage tank (10) through the action of gravity and is discharged to the outside.

When raining, rainwater on the roof flows downwards and flows into the rainwater storage tank (10) after passing through the water inlet pipe (20) and the regulating tank (60). When the water level in the rainwater storage tank (10) gradually rises and reaches the alarm water level, the water level alarm (30) arranged on the rainwater storage tank (10) sends out an alarm or other signals, and when the control unit (not shown) receives the alarm or other electric signals, a control instruction is sent out to start the drainage pump (51). Thus, the rainwater in the rainwater storage tank (10) is directly discharged to the outdoor through the drain pipe (52), thereby preventing adverse consequences caused by overflow of the rainwater storage tank (10). Those skilled in the art will appreciate that the control unit having the above capabilities can be easily implemented and will not be described in detail herein. Of course, the operation can also be performed manually, for example, when the alarm of the water level alarm (30) is heard, the drainage pump (51) is started manually.

In addition, the water level alarm (30) may alarm when the liquid level drops to a certain level, and the control unit may turn off the drain pump (51) after receiving the signal.

When an accident occurs, such as power loss or a fault of the drainage pump (51), the water level continues to rise to the overflow port (53), and the water can overflow and drain to the outdoor rainwater ditch by gravity, namely, the structure of the embodiment can realize double protection. The lower half part of the rainwater pipe from the roof to the rainwater storage tank is pressure-bearing when overflow occurs, so that the rainwater pipe and the connector thereof are ensured to be free of leakage and to be safe and reliable.

The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the device and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
