For example, the invention patent with application number 202311591062X discloses an energy-saving and environmentally friendly water tank for construction. Its basic structure is to set a trough body on the top of the water tank, collect rainwater through the trough body, and then filter the rainwater through the filter screen and store it in the water tank. An overflow pipe is set in the water tank. When the water level in the water tank exceeds the limit, the excess water is discharged to the outside of the water tank;

[0003] The problem of the above prior art is that dust will accumulate in the tank body at the top of the water tank during long-term placement, and dust will also be mixed in rainwater. The tank body does not block the dust, which increases the burden on the filter screen.

[0004] Secondly, since the overflow pipe is set in the water tank, although it can maintain the water level of the water tank, all the rainwater received will be filtered through the filter. If the rainfall is heavy, the filter will bear unnecessary burden. Utility Model Content

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, an energy-saving and environment-friendly water tank for construction provided by an embodiment includes a water tank 1, a water collecting tank 12 is arranged on the top surface of the water tank 1, a vertical downpipe 4 communicating with the inside of the water tank 1 is arranged on the bottom surface of the water collecting tank 12, the top of the downpipe 4 is higher than the bottom surface of the water collecting tank 12, a sleeve 41 is arranged inside the downpipe 4, the top of the sleeve 41 extends from the top of the downpipe 4, a water inlet pipe 42 with a hollow side wall is arranged on the top of the sleeve 41, the outer diameter of the water inlet pipe 42 is larger than the outer diameter of the downpipe 4, the water inlet pipe 4 has buoyancy, for example, it is made of plastic material, and the buoyancy provided by it enables it to float near the water surface of the water collecting tank 12, specifically, when there is a certain height of water in the water collecting tank 12, the liquid level is maintained in the middle of the water inlet pipe 4;

[0025] A filter basket 44 is arranged inside the water tank 1, and filter cotton or filter net is arranged inside the filter basket 44. The filter basket 44 is arranged directly below the sleeve 41. An overflow pipe 45 is arranged vertically penetrating the filter basket 44. The top of the overflow pipe 45 is lower than the top of the side wall of the filter basket 44. The bottom of the overflow pipe 45 is connected to a drainage pipe (not shown). The drainage pipe can be an elastic hose. One end of the drainage pipe away from the overflow pipe 45 is connected to the outside of the water tank 1, and the water outlet end of the drainage pipe is located below the filter basket 44.

[0026] The water collecting tank 12 is a rectangular tank, and four horizontally arranged strip-shaped floating plates 31 are arranged above the bottom surface of the water collecting tank 12. The four floating plates 31 are respectively adjacent to the four inner side walls of the rectangular tank 12.

[0027] The flip plate 3 is rotatably arranged on the floating plate 31, the middle part of the bottom end of the flip plate 3 is hinged to the top of the floating plate 31, and the top of the flip plate 3 is inclined toward the outside of the water collecting tank 12;

[0028] Vertically penetrating guide holes (not shown) are provided at both ends of the floating plate 31 , and vertical guide rods 32 are provided in the guide holes. The bottom ends of the guide rods 32 are fixedly connected to the bottom surface of the water collecting tank 12 .

[0029] When it rains, rainwater is collected by the water collection tank 12. As the water level in the water collection tank 12 rises, the water inlet pipe 42 drives the sleeve 41 to float, and the dust in the rainwater and the dust in the water collection tank 12 settle downward. Due to its own buoyancy, the water inlet pipe 42 floats near the water surface. Water flows in from the side wall of the water inlet pipe 12, is filtered by the filter cotton on the filter basket 44, and falls into the water tank 1. If the amount of water flowing into the water inlet pipe 12 is too large, the water level in the filter basket 44 rises until it flows out from the overflow pipe 45 through the drainage pipe, so as to prevent the unfiltered water from mixing with the clean water in the water tank 1.

[0030] When there is no water in the water collection tank 12, the floating plate 31 is located at the bottom of the water collection tank 12, and the flip plate 3 is tilted toward the outside of the water collection tank 12. As the water level inside the water collection tank 12 rises, the floating plate 31 floats up, driving the flip plate 3 to rise, and the flip plate 3 extends toward the outside of the water collection tank 12 to increase the area of ​​the device that receives rainwater. When the rain stops, as the remaining accumulated water in the water collection tank 12 evaporates, the gravity of the floating plate 31 itself causes the flip plate 3 to move downward and resume as Figure 3 In the state shown, the flip plate 3 is stored in the water collecting tank 12.

[0031] Preferably, the floating plate 31 can be a hollow metal plate with strong buoyancy and a certain gravity, and the flip plate 3 is a thin plastic plate with a light weight.

[0032] Furthermore, a through hole (not shown) is provided on the bottom surface of the water collecting tank 12, and the filter basket 44 is located within the vertical projection range of the through hole;

[0033] The through hole is covered with a cover plate 5, and the downpipe 4 passes through the cover plate 5 and is fixedly connected thereto. The outer edge of the top surface of the cover plate 5 has an annular outer extension 51, and the inner edge of the inner bottom end of the through hole has an annular inner extension (not shown). The outer extension 51 and the inner extension are of comparable size, and an annular sealing strip, such as a rubber sealing strip, is provided on the bottom surface of the outer extension 51 and / or the top surface of the inner extension.

[0034] A conical baffle plate 43 is provided above the water inlet pipe 42, and the baffle plate 43 is fixedly connected to the top of the cover plate 5 through a plurality of support rods (not shown);

[0035] When the filter cotton needs to be replaced, the baffle 43 is pulled up to lift out the cover plate 5 and the filter basket 44. After replacing the filter cotton, the cover plate 5 is put back into the through hole. The outer extension 51 and the inner extension are fitted together and sealed by the sealing strip therebetween. When it rains, the baffle 43 can prevent rainwater from falling directly into the water inlet pipe.

[0036] Furthermore, a limit plate 321 is provided at the top of the guide rod 32, and the limit plate 321 is lower than the top of the side wall of the water collecting tank 12. The limit plate 321 can limit the lifting height of the floating plate 31 and can also limit the maximum rotation angle of the flip plate 3. For example, when the flip plate 3 flips to the limit, the angle between it and the bottom surface of the water collecting tank 12 is 30 degrees.

[0037] In another embodiment, if Figure 4 As shown, an L-shaped rod 2 is set on the top of the floating plate 31. When the floating plate 31 is in a non-floating state, the end of the horizontal section of the L-shaped rod 2 is adjacent to the flip plate 3. The L-shaped rod 2 is located on the side of the flip plate 3 away from the inner wall of the water collecting tank 12. This can prevent the flip plate 3 from flipping into the water collecting tank 12 when it is affected by external forces, such as wind.

[0038] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
