[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-5 A screw-on anti-backflow well seat comprises a protective cover seat 1, a waterproof blind plate 2 is provided in the middle of the protective cover seat 1, and a baffle 3 is installed on the inner wall of the protective cover seat 1 and above the corresponding waterproof blind plate 2, and a vent hole 21 is provided in the middle of the top of the waterproof blind plate 2. It is worth mentioning that the materials of the protective cover seat 1, the waterproof blind plate 2 and the baffle 3 are all made of high-strength and corrosion-resistant SMC fiberglass.

[0020] At the same time, a first groove is opened at the top of the protective cover seat 1, and a through hole is opened in the middle of the bottom of the first groove of the protective cover seat 1, and a screw buckle groove 11 is opened at the bottom of the groove of the protective cover seat 1 and outside the through hole, and the protective cover seat 1, the screw buckle groove 11 and the baffle 3 are integrally pressed and formed.

[0021] In addition, a sub-groove 22 is provided outside the bottom of the waterproof blind plate 2 and between the first groove and the through hole of the corresponding protective cover seat 1, wherein the bottom of the waterproof blind plate 2 is located on one side of the sub-groove 22 and on the side away from the middle of the waterproof blind plate 2 and is clamped into the screw buckle groove 11 of the corresponding protective cover seat 1, thereby completing the clamping of the waterproof blind plate 2 and the corresponding protective cover seat 1.

[0022] In addition, a placement groove is provided at the top of the sub-groove 22 of the waterproof blind plate 2, and a sealing ring 4 is provided in the placement groove. It is worth mentioning that the sealing ring 4 is an EPDM sealing ring, and the EPDM sealing ring is an existing structure and technology, so it is not elaborated in detail.

[0023] Furthermore, a second groove is opened in the middle of the top of the waterproof blind plate 2, and a vent hole 21 is opened in the middle of the top of the second groove. At the same time, a through hole is opened in the middle of the top of the baffle 3 at the corresponding second groove of the waterproof blind plate 2.

[0024] In the present embodiment, the waterproof blind plate 2 is clamped into the corresponding screw groove 11 of the protective cover seat 1 by clamping the bottom of the waterproof blind plate 2 on one side of the sub-groove 22 and on the side away from the middle of the waterproof blind plate 2. The waterproof blind plate 2 and the corresponding protective cover seat 1 are clamped together. At the same time, the sealing performance is ensured by the sealing ring 4 during this process.

[0025] At the same time, when it is rainy season and the water level in the underground pipe network is normal, the rainwater flows along the baffle 3 of the protective cover seat 1 to the top of the waterproof blind plate 2 and flows into the underground pipe network along the air vents 21 on the top of the waterproof blind plate 2.

[0026] When the water level in the underground pipe network rises, the accumulated water and sewage inside the underground pipe network moves upward along the bottom of the protective cover seat 1 and the bottom of the waterproof blind plate 2. During the movement, the sealing ring 4 ensures the sealing performance of the waterproof blind plate 2 and the protective cover seat 1, and the baffle plate 3 has a limiting and resisting effect on the waterproof blind plate 2, thereby reducing the phenomenon of the accumulated water and sewage in the underground pipe network flowing back to the ground.

[0027] In the utility model, when the water level in the underground pipe network rises, the accumulated water and sewage inside the underground pipe network move upward along the bottom of the protective cover seat 1 and the bottom of the waterproof blind plate 2, and the sealing performance of the waterproof blind plate 2 and the protective cover seat 1 is ensured by the sealing ring 4, and the waterproof blind plate 2 is limited and resisted by the baffle plate 3, thereby reducing the phenomenon of the accumulated water and sewage in the underground pipe network flowing back to the ground.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
