Description

Technical Field

[0001] This utility model mainly relates to the field of artificial water feature technology, specifically a new type of artificial water feature overflow device. Background Technology

[0002] With economic development and improved living standards, people are placing greater emphasis on green and healthy lifestyles. They are no longer simply pursuing spaciousness and convenience but are increasingly concerned with external landscape features. This has led to the emergence of many artificial landscapes, among which artificial water features are frequently used due to their unique artistic effect and peaceful atmosphere. Existing artificial water features generally use side-wall overflow outlets, with water level regulation relying on a fixed height. This makes them susceptible to fluctuations in water flow and difficult to meet the needs of high-precision landscapes (such as mirror pools and ecological wetlands). Furthermore, they typically only use a single-layer filter at the overflow outlet, making the pipes prone to blockage by large particles, requiring frequent manual cleaning. Utility Model Content

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 6As shown, a novel artificial water feature overflow device includes a drain pipe 1 and an overflow pipe 2. The drain pipe 1 connects to a rainwater well 4 and an external sewage treatment system, thereby discharging excess water accumulated in the rainwater well 4. The overflow pipe 2 connects to a water feature pool 3 and the rainwater well 4. The overflow pipe 2 has a U-shaped structure, with a fixed outlet 21 and a movable overflow outlet 22 connected to its two ends, respectively. The movable overflow outlet 22 includes a movable pipe 222 movably connected to one end of the overflow pipe 2. An adjustment component 225 is fixedly installed on the outer wall of the overflow pipe 2, and a limit ring 223 is fixedly installed on the outer wall of the movable pipe 222. The adjustment component 225 drives the limit ring 223 to move and extend. Screens 224 are provided at both ends of the overflow pipe 2. A vortex guide groove 23 is formed on the inner wall of the overflow pipe 2. The surface of the vortex guide groove 23 is coated with a hydrophobic layer to prevent water from remaining in the vortex guide groove 23.

[0030] The adjusting assembly 225 includes a housing 2254 fixedly connected to the outer wall of the overflow pipe 2. A movable groove 2255 is formed on the side of the housing 2254 near the movable pipe 222. A connecting block 2232 is fixedly provided on the outer wall of the limiting ring 223. The connecting block 2232 is slidably connected to the movable groove 2255. A driven rack 2253 is fixedly connected to one side of the connecting block 2232. A waterproof motor 2251 is fixedly provided inside the housing 2254. The output end of the waterproof motor 2251 is connected to a drive gear 2252 that meshes with the driven rack 2253. The waterproof motor 2251 controls the drive gear 2252 to rotate, thereby driving the driven rack 2253 to move up and down in the height direction. In turn, with the cooperation of the connecting block 2232, the limiting ring 223 moves synchronously.

[0031] The bottom of the limiting ring 223 is provided with multiple buffer blocks 2231 at equal intervals along the circumference. When the limiting ring 223 moves to the position of tightly abutting the overflow pipe 2, the buffer blocks 2231 are in full contact with the top of the overflow pipe 2. The buffer blocks 2231 prevent the limiting ring 223 from directly colliding with the overflow pipe 2 after it moves down, thus avoiding damage.

[0032] A rubber ring 2221 is fixedly installed at the bottom of the movable pipe 222. The rubber ring 2221 is in elastic contact with the inner wall of the overflow pipe 2. The rubber ring 2221 provides an elastic seal between the movable pipe 222 and the inner wall of the overflow pipe 2, preventing water from leaking out along the connection between the movable pipe 222 and the overflow pipe 2 and affecting the overflow speed.

[0033] The movable tube 222 has a cleaning port 2222, which is located horizontally above the limiting ring 223. A sealing cap 226 is inserted into the cleaning port 2222. The horizontal cross-section of the sealing cap 226 is shaped like a convex character. Sealing strips 2261 are fixedly installed on the recessed parts on both sides of the sealing cap 226. The sealing strips 2261 are made of rubber. A sealing groove 2223 is formed on the cleaning port 2222 to fit the sealing strips 2261. The sealing cap 2261 and the sealing groove 2223 are elastically engaged to provide a detachable seal between the sealing cap 226 and the cleaning port 2222.

[0034] A pull handle 2262 is fixedly installed on one outer wall of the sealing cover 226.

[0035] The two screens 224 are located at the top of the movable overflow port 21 and the fixed water outlet 22, respectively. The fixed water outlet 22 is also provided with a cleaning port 2222 and a sealing cover 226. Both cleaning ports 2222 are located below the screens 224, so that the cleaning position can be selected according to the water flow direction when adding or draining water from the water feature pool 3.

[0036] A water level sensor 221 is fixedly installed on the top side wall of the movable pipe 222, and the actual water level in the rainwater well 4 is monitored in real time by the water level sensor 221.

[0037] A water stop valve 5 is installed in the overflow pipe 2 inside the rainwater well 4 to control the flow of water in the overflow pipe 2.

[0038] The implementation principle of this application embodiment is as follows: When this device is used, after the rainwater stored in the rainwater well 4 exceeds the top of the movable overflow port 22, the rainwater flows along the U-shaped overflow pipe 2 and flows into the water feature pool 3 from the fixed outlet 21. The water level in the water feature pool 3 is consistent with the height of the movable overflow port 22. Adjusting the water level in the water feature pool 3 only requires remote control of the waterproof motor 2251 to work. Under the meshing of the drive gear 2252 and the driven rack 2253, the movable pipe 222 moves and adjusts along the height direction, thereby accurately adjusting the water level in the water feature pool 3.

[0039] During operation, the external water flow first needs to pass through the screens 224 at both ends for double screening of large particles of impurities. The vortex guide channel 23 increases the water flow velocity to prevent small particles of impurities from accumulating and merging in the overflow pipe 2, thereby reducing the probability of blockage in the overflow pipe 2. The water level sensor 221 monitors the actual water level in the rainwater well 4 in real time. If the actual height is inconsistent with the theoretical height after adjustment by the waterproof motor 2251, a blockage may occur, and an alarm message will be sent to the staff so that they can carry out timely inspection and clearing of the blockage.

[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
