DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The utility model relates to a pool water discharge device, which comprises an outer pipe 100, a water receiving pipe 200 and an inner pipe 300.

[0029] like Figure 1 、 Figure 2 and Figure 3As shown, the outer tube 100, the water receiving pipe 200, and the inner tube 300 are all hollow tubes. The outer tube 100 can be a straight tube placed vertically, while the water receiving pipe 200 can be configured as a curved tube. One end of the water receiving pipe 200 is defined as the first end 210, and the first end 210 is connected to the lower end of the outer tube 100. It is understood that the first end 210 and the lower end of the outer tube 100 can be coaxially connected by configuring an adapter tube. In this embodiment, the first end 210 is coaxially inserted into the lower end of the outer tube 100 from bottom to top. The outer wall of the first end 210 and the inner wall of the lower end of the outer tube 100 are tightly fitted to prevent water leakage. Glue can be applied between the two to further seal them. A sealing ring 220 is provided on the inner wall of the first end 210. The sealing ring 220 extends in a closed circular ring shape along the circumference of the first end 210. The sealing ring 220 is integrally formed on the inner wall of the first end 210. A first sealing surface 221 is provided on the sealing ring 220, and the first sealing surface 221 faces the central axis of the water receiving pipe 200. The first sealing surface 221 is conical, and the first sealing surface 221 gradually decreases from top to bottom. The inner tube 300 can be slidably installed in the outer tube 100. The outer diameter of the inner tube 300 is smaller than the inner diameter of the outer tube 100, so that there is a certain gap between the inner tube 300 and the outer tube 100. The gap allows water to flow. Among them, a sealing ring 400 is installed at the lower end of the inner tube 300, and the outer wall of the sealing ring 400 has a second sealing surface 410. The second sealing surface 410 is conical, and the outer diameter of the second sealing surface 410 gradually decreases from top to bottom. The conical shapes of the first sealing surface 221 and the second sealing surface 410 are adapted to each other. It can be understood that the maximum inner diameter of the first sealing surface 221 is smaller than the maximum outer diameter of the second sealing surface 410, and the minimum inner diameter of the first sealing surface 221 is larger than the minimum outer diameter of the second sealing surface 410. As Figure 3 and Figure 4 As shown, when the inner tube 300 moves downward to the lowest position in the outer tube 100, the inner tube 300 drives the sealing ring 400 into the first end 210, and the second sealing surface 410 of the sealing ring 400 abuts the first sealing surface 221 of the sealing ring 220, and the first sealing surface 221 and the second sealing surface 410 are tightly fitted together. Because the first sealing surface 221 and the second sealing surface 410 are tapered, the further the inner tube 300 moves downward, the tighter the contact between the first sealing surface 221 and the second sealing surface 410 becomes, thereby sealing the first end 210. Water in the water receiving pipe 200 cannot flow directly from the first end 210 into the outer tube 100, and can only flow upward into the inner tube 300. At the same time, when the pressure of the first sealing surface 221 on the second sealing surface 410 has a component force toward the central axis of the inner tube 300, the sealing ring 400 is more closely attached to the outer wall of the inner tube 300, which is equivalent to increasing the sealing performance between the sealing ring 400 and the inner tube 300. Figure 5As shown, when the inner tube 300 moves upward relative to the outer tube 100, the sealing ring 400 separates from the sealing ring 220, and the first sealing surface 221 and the second sealing surface 410 separate from each other. Water in the water receiving pipe 200 can flow directly from the first end 210 into the outer tube 100. The other end of the water receiving pipe 200 can be connected to a pool. Depending on the position of the inner tube 300, the water in the pool can be controlled to flow into the inner tube 300 or the outer tube 100 after passing through the first end 210, thereby achieving different usage functions. The sealing method between the sealing ring 400 and the sealing ring 220 can effectively ensure the sealing of the connection between the inner tube 300 and the water receiving pipe 200, preventing water from leaking from the connection between the inner tube 300 and the water receiving pipe 200 into the outer tube 100.

[0030] In one embodiment, if Figure 2 and Figure 4 As shown, a mounting groove 310 is provided on the outer wall of the lower end of the inner tube 300. The mounting groove 310 is arranged along the circumference of the inner tube 300, so that the mounting groove 310 is annular. The sealing ring 400 is sleeved in the mounting groove 310. The axial position of the sealing ring 400 is fixed by the mounting groove 310, and the sealing ring 400 is restricted from moving axially relative to the inner tube 300, ensuring that when the inner tube 300 moves down until the sealing ring 400 abuts against the sealing ring 220, the sealing ring 400 is stably pressed down on the sealing ring 220 under the action of the mounting groove 310. It can be understood that the inner wall of the sealing ring 400 close to the central axis is tightly fitted on the groove wall of the mounting groove 310 close to the central axis. Specifically, the upper and lower sides of the mounting groove 310 are the upper groove wall 311 and the lower groove wall 312 respectively. After the sealing ring 400 is fitted into the mounting groove 310, its upper side abuts the upper groove wall 311, which restricts upward movement of the sealing ring 400 relative to the inner tube 300. Its lower side abuts the lower groove wall 312, which restricts downward movement of the sealing ring 400 relative to the inner tube 300. The outer diameter of the lower groove wall 312 is smaller than the minimum inner diameter of the first sealing surface 221. Alternatively, the lower groove wall 312 may extend radially outward from the lower edge of the inner tube 300. When the inner tube 300 moves downward relative to the outer tube 100, the lower end of the inner tube 300, along with the lower groove wall 312, enters the first end 210. At least a portion of the second sealing surface 410 enters the first end 210 and abuts against the first sealing surface 221.

[0031] Based on the above embodiment, the outer wall of the inner tube 300 is provided with a plurality of circumferentially distributed reinforcing ribs 320, with spacing between each rib 320. Each rib 320 extends axially along the inner tube 300, with the lower end of the rib 320 connected to the upper side of the upper groove wall 311. It is understood that two, three, or more ribs 320 may be provided. The ribs 320 are integrally formed on the outer wall of the inner tube 300. The provision of the ribs 320 strengthens the axial structural strength of the upper groove wall 311 of the mounting groove 310. When the inner tube 300 presses the sealing ring 400 downward onto the sealing ring 220, the sealing ring 400 exerts an upward thrust on the upper groove wall 311. The ribs 320 prevent upward deformation of the upper groove wall 311, thereby ensuring that the sealing ring 400 is securely fixed in the mounting groove 310.

[0032] The shape of the reinforcing rib 320 may include, but is not limited to, a strip, a plate, or a block. In this embodiment, the reinforcing rib 320 is in the shape of a right triangle. One right-angled side of the reinforcing rib 320 is formed on the outer wall of the inner tube 300 along the axial direction of the inner tube 300, while the other right-angled side (the lower side) of the reinforcing rib 320 is formed on the upper side of the upper groove wall 311. This right-angled triangle shape ensures the structural strength of the reinforcing rib 320 while preventing excessive stress on the inner tube 300 during molding, which could cause local deformation of the inner tube 300.

[0033] In one embodiment, Figure 2 and Figure 4 As shown, the inner wall of the inner tube 300 is provided with a flange 330 that protrudes radially inward. The flange 330 and the upper groove wall 311 are located in the same radial plane of the inner tube 300, that is, the flange 330 and the upper groove wall 311 of the mounting groove 310 are at the same height. The provision of the flange 330 improves the structural strength of the inner tube 300 at the location where the flange 330 is located. Combined with the upper groove wall 311 being at the same height, this prevents inward or outward deformation of the inner tube 300 at the corresponding location. When the inner tube 300 presses the sealing ring 400 downward onto the sealing ring 220, it can withstand a significant downward force.

[0034] In one embodiment, Figure 1As shown, the outer tube 100 has a first opening 110 and a second opening 120 defined in its sidewall. The outer tube 100 is positioned vertically, with the first opening 110 located above the second opening 120. Both the first opening 110 and the second opening 120 provide radial communication between the interior and exterior of the outer tube 100. A third opening 340 is defined in the upper sidewall of the inner tube 300, providing radial communication between the interior and exterior of the inner tube 300. During axial movement of the inner tube 300 relative to the outer tube 100, the third opening 340 remains above the second opening 120. In actual use, the water inlet pipe 200 connects to the bottom of the aquaculture pond. When the aquaculture pond does not need to be drained, the inner tube 300 is lowered until the sealing ring 400 abuts the sealing ring 220, allowing water from the aquaculture pond to flow through the water inlet pipe 200 into the inner tube 300. The inner tube 300, water inlet pipe 200, and aquaculture pond form a U-shaped pipe structure. like Figure 3 As shown, the height of the water in the inner tube 300 is the height of the water in the breeding pond. The user can observe the water level in the inner tube 300 through the first opening 110 and the third opening 340, and thus know the water level in the breeding pond. If the water level in the breeding pond rises above the third opening 340, the water will overflow from the inner tube 300 through the third opening 340 into the gap between the outer tube 100 and the inner tube 300, and then flow downward and be discharged from the second opening 120. Figure 5 As shown, when a large amount of water needs to be drained from the aquaculture pond, the inner tube 300 is moved upward, and the sealing ring 400 is separated from the sealing ring 220. The water in the aquaculture pond flows directly into the outer tube 100 through the water receiving pipe 200 and is quickly discharged from the second opening 120. When the inner tube 300 is moved axially downward to its lowest position relative to the outer tube 100, the highest point of the third opening 340 is no lower than the lowest point of the first opening 110. This prevents the first opening 110 from obstructing the user's view of the third opening 340.

[0035] It is understood that the movement of the inner tube 300 can be manually pulled or electrically driven by an external electronic control component. Figure 1 and Figure 3 As shown, the outer tube 100 also includes a cylinder 500. For example, the top of the outer tube 100 is sealed with a cover, and the cylinder 500 is mounted above the cover. The cylinder 500 is located at the top of the outer tube 100. The drive shaft of the cylinder 500 passes through the cover and is connected to the inner tube 300. The extension and contraction of the drive shaft of the cylinder 500 drives the inner tube 300 to move axially relative to the outer tube 100.
