[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1 - 4, A new type of adjustable rainwater volume attachment in the illustration, including a rainwater riser 1. In the middle of the bottom opening of the rainwater riser 1, an attachment 3 for adjusting the rainwater volume is hinged through an elastic shaft 2. The attachment 3 for adjusting the rainwater volume can be opened downward by 90 degrees. A number of water-permeable pores 4 are provided on the surface of the attachment 3 for adjusting the rainwater volume. By adding the new attachment 3 for adjusting the rainwater volume at the end of the gravity-flow rainwater riser 1, the present utility model can adjust the opening angle of the attachment according to the rainwater volume, adjust the flow rate of the rainwater. At the same time, when it is in heavy rain, the rainwater riser 1 is filled with water, generating a certain negative pressure in the rainwater riser 1, producing a siphon effect on the discharge of roof rainwater, achieving the effect of increasing the rainwater discharge volume. And by setting this new attachment 3 for adjusting the rainwater volume at the end of the rainwater riser 1, the effect of preventing insects and rodents can be achieved.
[0018] Furthermore, the attachment 3 for adjusting the rainwater volume is a semi-circular cover plate. After two attachments 3 for adjusting the rainwater volume are spliced together through the elastic shaft 2, they can block the bottom opening of the rainwater riser 1, and can block the bottom opening of the rainwater riser 1 when the rain stops to prevent snakes, insects and rodents from entering; furthermore, the attachment 3 for adjusting the rainwater volume is made of metal material, with a long service life; further, the elastic shaft 2 includes a hinge that can be opened downward by 90 degrees at both ends, which is convenient for opening the attachment 3 for adjusting the rainwater volume downward; further, a spring with both ends fixedly installed on the elastic shaft 2 is arranged outside the hinge shaft of the hinge, which can make the opened attachment 3 for adjusting the rainwater volume automatically reset when the rain stops.
[0019] In this solution, when in use, by adding the new attachment 3 for adjusting the rainwater volume at the end of the gravity-flow rainwater riser 1, the present utility model can adjust the opening angle of the attachment according to the rainwater volume, adjust the flow rate of the rainwater. At the same time, when it is in heavy rain, the rainwater riser 1 is filled with water, generating a certain negative pressure in the rainwater riser 1, producing a siphon effect on the discharge of roof rainwater, achieving the effect of increasing the rainwater discharge volume. And by setting this new attachment 3 for adjusting the rainwater volume at the end of the rainwater riser 1, the effect of preventing insects and rodents can be achieved. It can automatically adjust the instantaneous rainwater discharge volume according to the heavy rain state or light rain state. When the rainwater volume is small, the rainwater is discharged through the water-permeable pores 4, reducing the rainwater flow rate. When the rainwater volume is large, the speed of the rainwater pouring into the rainwater riser 1 is greater than the speed of the water flowing out of the water-permeable pores 4 at the bottom of the rainwater riser 1, and the rainwater riser 1 can be filled with rainwater. And when it is filled to a certain height, according to the water pressure above it, the elastic shaft 2 adaptively and automatically increases the opening angle of the attachment 3 for adjusting the rainwater volume, increasing the rainwater flow rate, so as to achieve the effect of adjusting the rainwater discharge volume. When the rain is small or even stops, the water in the rainwater riser 1 is drained, and the elastic shaft 2 can make the attachment 3 for adjusting the rainwater volume that is pressed down and opened automatically close upward under the action of the spring, and block the bottom opening of the rainwater riser 1 when the rain stops.
