[0023] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0024] Example:
[0025] like Figure 1-Figure 4 As shown, the utility model provides a drainage pipe sealing device based on the capillary effect, including a sealing assembly 1 arranged at the end of the drainage pipe, the sealing assembly 1 including a sealing shell 11, a guide plate 12 and a capillary assembly 13. The sealing shell 11 has an inner cavity 2, and the inner cavity 2 has a sealing plate 3 arranged therein. The sealing plate 3 cooperates with the inner cavity 2 to form a drainage chamber. The guide plate 12 is formed in the drainage chamber, and the capillary assembly 13 is provided in the guide plate 12.
[0026] The sealing assembly 1 also includes a drain port 14, which is opened on one side of the sealing shell 11. The outside of the drain port 14 is connected to a drain pipe 4, which is connected to an external water tank. When draining, the main drain valve of the water tank is closed, and the drain pipe 4 connected to the water tank is equivalent to being closed, so that the drainage chamber can be closed.
[0027] An exhaust pipe 5 is provided on the top of the sealing plate 3, and the exhaust pipe 5 is connected to the external negative pressure forming component. The exhaust pipe 5 connects the drainage chamber with the external negative pressure forming component. The external negative pressure forming component uses technologically mature exhaust equipment and a matching power component. After the drain pipe 4 is closed, the external negative pressure forming component works to gradually extract the air in the drainage chamber. As the gas is gradually extracted, negative pressure is formed in the drainage chamber. Under the action of negative pressure, the water in the drain pipe gradually enters the drainage chamber through the capillary component 13.
[0028] The guide plate 12 is designed to be inclined, and the end of the guide plate 12 is flush with the opening position of the drain outlet 14. The water entering the drainage chamber flows quickly to the drain outlet 14 under the guidance of the guide plate 12, and enters the drain pipe 4 through the drain outlet 14. The water entering the drain pipe 4 enters the water storage device under the guidance of the drain pipe 4. The inclined design of the guide plate 12 allows the water to be quickly discharged from the drainage chamber, avoiding the water from remaining in the drainage chamber.
[0029] The capillary components 13 are provided in several groups, and the capillary components 13 are distributed in the guide plate 12. Each group of capillary components 13 is designed to be inclined in accordance with the guide plate 12. The water entering the drainage chamber from the capillary component 13 can quickly converge to one side along the guide plate 12. The capillary component 13 is composed of several groups of capillary tubes 131 arranged in parallel. The specifications of each group of capillary tubes 131 are the same, and each group of capillary tubes 131 is designed to be thin at the top and wide at the bottom. The wide-thin transition section of the capillary tube 131 is rounded. When drainage begins, the capillary component 13 extends into the drain pipe, which can reduce the power of vacuuming, so that the water in the soft foundation can be effectively discharged.
[0030] After drainage has been going on for a certain period of time, the drainage rate slows down. When the water level in the drainage pipe stays at the bottom interface of the capillary component 13, the water level in the drainage pipe will rise to the top surface of the capillary component 13 under the capillary action, so that drainage can continue, ensuring that the soft foundation drainage meets the requirements.
[0031] The lower end of the sealing shell 11 is annular and matches the drain pipe. The sealing shell 11 is sleeved on the end of the drain pipe through the annular design of the lower end. A sealing gasket 6 is attached to the surface of the annular part of the lower end of the sealing shell 11. The sealing gasket 6 contacts the end of the drain pipe under the pressure of the sealing shell 11. After the sealing shell 11 is sleeved to the end of the drain pipe, the sealing gasket 6 can ensure the sealing of the connection between the sealing shell 11 and the sealing gasket 6, so that the drainage chamber always maintains a negative pressure state, and the water in the drain pipe can be continuously discharged under the action of negative pressure.
[0032] In this embodiment, the drainage pipe is buried in the soft soil foundation. The water in the soft soil foundation enters the drainage pipe under the action of pressure. The water in the drainage pipe moves upward under the action of negative pressure and enters the capillary component 13. Under the action of the capillary effect, the capillary component 13 sends the water into the upper surface of the guide plate 12, and the water is discharged along the upper surface of the guide plate 12. In addition to being used for drainage of soft soil foundations, this equipment can also be used for other pumping equipment based on the negative pressure drainage principle.
[0033] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
