Technical Field

[0001] The utility model relates to the technical field of curtain wall building drainage, and particularly relates to a drainage part and a drainage structure. Background Art

[0002] In the glass curtain wall building structure, multiple fixed connection structures are usually arranged on the building structure to install and fix large glass panels on the building structure, so as to complete the installation and construction of the glass curtain wall. However, due to actual technical short - board problems, there are often gaps between the fixed connection structures and the glass. Therefore, whenever it rains, the rainwater outside the glass curtain wall may seep into the gaps between the inner - layer structures through the gaps between the outer - layer structures. And the rainwater contains various substances, which may cause the corrosion of each connection structure over time. Therefore, how to do a good job in the drainage between such buildings urgently needs to propose a solution. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a drainage part and a drainage structure, which can automatically reset the position of the drainage part in the drainage structure and prevent water from flowing back into the building.

[0004] The technical solution of the utility model is realized as follows:

[0005] A drainage part includes a rotating shaft, a long baffle and a short baffle. The long baffle is connected to the rotating shaft, and the short baffle is connected to the side of the long baffle close to the rotating shaft.

[0006] Preferably, the short baffle is connected to one end of the long baffle where the long baffle is connected to the rotating shaft.

[0007] Preferably, the included angle between the long baffle and the short baffle is 20° - 110°.

[0008] Preferably, the length ratio of the short baffle to the long baffle is 1:1.8 - 1:3.

[0009] Preferably, the rotating shaft, the long baffle and the short baffle are integrally formed.

[0010] The utility model also provides a drainage structure, which includes a drainage valve, a fastener and a first gasket. The drainage valve is internally provided with the above - mentioned drainage part. The drainage valve is fixed in the building gap through the fastener. The rotating shaft of the drainage part is rotatably connected inside the drainage valve. The sum of the longitudinal height of the long baffle and the diameter of the rotating shaft is not greater than the height of the water flow channel in the drainage valve. The short baffle is arranged towards the water inlet of the drainage valve. The first gasket is arranged between the fastener and the building structure, and a first opening adapted to the water inlet of the drainage valve is opened on the first gasket.

[0011] Preferably, the sum of the longitudinal height of the long baffle and the diameter of the rotating shaft has an interference fit with the height of the water flow channel in the drain valve.

[0012] Preferably, the drain valve includes an integrally formed water flow part and a water outlet part. The water flow part is located inside the building hole, and the water outlet part is located outside the building hole.

[0013] Preferably, it further includes a second gasket. The second gasket is arranged between the water outlet part and the building structure, and a second opening adapted to the water outlet of the water flow part is provided on the second gasket.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] The present utility model is installed and fixed in a building gap. Among them, a first opening adapted to the water inlet of the drain valve is provided on the first gasket. Through the action of the first gasket, water flows from the first opening into the drain valve, and the sealing performance between the drain valve and the building gap can be enhanced to avoid water leakage. During drainage, water flows into the drain valve from the water inlet. When only a small amount of water needs to be discharged, the water flows from below the long baffle of the drainage part to the water outlet of the drain valve and is then discharged outside the building gap where this drainage structure is installed; when a large amount of water needs to be discharged, due to the certain weight and impact force of the water flow, it will automatically push open the long baffle, causing it to rotate along the rotating shaft to the side fitting the drain valve pipe wall to ensure that all the water can be discharged; when the water flow is exhausted, there is no longer any water flow acting in the drain valve. At this time, the long baffle and the short baffle reverse along the rotating shaft under the action of their own gravity until they return to their original positions. When water backflows in the drain valve, the long baffle can also block the reverse impact of the water flow in cooperation with the short baffle to prevent the water in the direction of the drain valve water outlet from flowing back into the water inlet.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 creative efforts shall fall within the protection scope of the present utility model.

[0027] See Figures 4 to 5 , an embodiment of the present utility model discloses a drainage part 11, including a rotating shaft 111, a long baffle 112 and a short baffle 113. The long baffle 112 is connected to the rotating shaft 111, and the short baffle 113 is connected to one side of the long baffle 112 close to the rotating shaft 111. This structure will be specifically described together in a drainage structure in the second aspect.

[0028] Furthermore, the short baffle 113 is connected to one end of the long baffle 112 where the long baffle 112 is connected to the rotating shaft 111. Specifically, the short baffle 113 is a counterweight of the long baffle 112, so that the long baffle 112 can reverse and reset itself without external force after rotation.

[0029] Furthermore, the included angle between the long baffle 112 and the short baffle 113 is 20° - 110°. Ensure that the long baffle 112 and the short baffle 113 can reverse and reset along the rotating shaft 111 under the action of their own gravity.

[0030] Further, the length ratio of the short baffle 113 to the long baffle 112 is 1:1.8 - 1:3.

[0031] Further, the rotating shaft 111, the long baffle 112 and the short baffle 113 are integrally formed, improving the stability of the drainage member 11.

[0032] See Figures 1 - 7 , a drainage structure is proposed in the second aspect of the present utility model, including a drainage valve 1, a fastener 2 and a first gasket 3. The drainage valve 1 is provided with the aforementioned drainage member 11. The drainage valve 1 is fixed in a building gap through the fastener 2. The rotating shaft 111 of the drainage member 11 is rotatably connected in the drainage valve 1. The sum of the longitudinal height of the long baffle 112 and the diameter of the rotating shaft 111 is not greater than the height of the water flow channel in the drainage valve 1. The short baffle 113 is arranged towards the water inlet of the drainage valve 1; the first gasket 3 is arranged between the fastener 2 and the building structure 4, and a first opening 31 adapted to the water inlet of the drainage valve 1 is provided on the first gasket 3.

[0033] Specifically, receiving holes 12 are provided on both sides of the rotating shaft 111 inside the drainage valve 1. The rotating shaft 111 is slightly longer than the width inside the drainage valve 1, and both ends are clamped and fixed on the receiving holes 12.

[0034] Specifically, both the short baffle 113 and the long baffle 112 have a certain weight, and the weight of the long baffle 112 is greater than that of the short baffle 113. Therefore, when the rotating shaft 111 is connected in the drainage valve 1 and drainage work is not required, the long baffle 112 is located on one side of the vertical line where the rotating shaft 111 is located, and the short baffle 113 is located on the other side of the vertical line where the rotating shaft 111 is located.

[0035] This utility model is installed and fixed in a building gap. Among them, a first opening 31 adapted to the water inlet of the drain valve 1 is provided on the first gasket 3. Through the action of the first gasket 3, water flows from the first opening 31 into the drain valve 1, and the tightness between the two can be enhanced when the drain valve 1 is arranged in the building gap to avoid water leakage. During drainage, water flows into the drain valve 1 from the water inlet. When only a small amount of water needs to be discharged, the water flows from below the long baffle 112 of the drainage part 11 to the water outlet of the drain valve 1 and is then discharged outside the building gap where this drainage structure is installed. When a large amount of water needs to be discharged, due to the certain weight and impact force of the water flow, it will automatically push open the long baffle 112, causing it to rotate along the rotating shaft 111 to the side fitting the pipe wall of the drain valve 1 to ensure that all the water flow can be discharged. When the water flow is exhausted and there is no longer any water flow acting in the drain valve 1, at this time, the long baffle 112 and the short baffle 113 reverse along the rotating shaft 111 under the action of their own gravity until they return to their original positions. When water backflows in the drain valve 1, the long baffle 112 can also block the reverse impact of the water flow in cooperation with the short baffle 113 to prevent the water in the direction of the water outlet of the drain valve 1 from flowing back into the water inlet.

[0036] Further, the sum of the longitudinal height of the long baffle 112 and the diameter of the rotating shaft 111 has an interference fit with the height of the water flow channel in the drain valve 1. The water flow has a certain weight and impact. When water flows into the drain valve 1 from the water inlet, the water will automatically push open the long baffle 112, causing it to rotate along the rotating shaft 111 towards the inner wall of the drain valve 1 to facilitate the rapid discharge of the water flow. And this length setting enables the long baffle 112 to also block the reverse impact of the water flow in cooperation with the short baffle 113 when water backflows in the drain valve 1, preventing the water flow from flowing back into the building.

[0037] Further, the drain valve 1 includes an integrally formed water flow part 13 and a water outlet part 14. The water flow part 13 is located inside the building hole, and the water outlet part 14 is located outside the building hole. The clearly separated water flow part 13 and water outlet part 14 ensure that the water flow can be completely discharged outside the building.

[0038] Further, it further includes a second gasket 5. The second gasket 5 is arranged between the water outlet part 14 and the building structure 4, and a second opening 51 adapted to the water outlet of the water flow part 13 is provided on the second gasket 5. The water flow flows out of the water outlet along the second opening 51 to the outside of the building.

[0039] Further, the fastener 2 is a bolt. Specifically, a number of screw holes adapted to the bolt are provided on the side wall of the drain valve 1. When the drain valve 1 is fixed to the building gap by the bolt, the bolt can simultaneously drive and press the first gasket 3 and the second gasket 5, making the two closely attached between the drain valve 1 and the building structure 4 to improve the connection stability and tightness.

[0040] Specifically, the first gasket 3 is provided with holes for mating with bolts, facilitating the bolts to pass through the first gasket 3 and connect to the drain valve 1.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
