Problems solved by technology

Due to different treatment or topography, the water level requirements of different downstream water levels cannot always be consistent. In such cases, another water level control system is often installed, which increases the cost.
[0004] 2. When the upstream water level control device shuts down or fails and the upstream water level no longer supplies water, or the downstream water level suddenly rises due to rainfall, artificial liquid addition and other factors, and the speed is inconsistent, or the water consumption speed of different downstream water levels is different, it is bound to Lead to cross-flow and pollution between different downstream water levels or even between upstream and downstream water levels
The check valve can solve the problem of cross-flow and pollution, but the effect is not good, because the check valve needs a certain starting pressure, and due to the problem of processing technology, the starting pressure of the check valve of the same type is also different. The operation will greatly affect the control accuracy of the downstream water level

Embodiment 1

[0031] Embodiment 1, the inverted siphon type water delivery device that the outlet pipe mouth floats out of the water surface, refer to figure 1 , including the upstream water level 102 of water supply, the inverted siphon and the downstream water level connected to the downstream water consumption device, wherein: the inverted siphon includes a water inlet 103, a water delivery pipe 104 and a water outlet, and the water delivery pipe 104 is connected to the water inlet 103 and the water outlet; The water end 103 is located at the upstream water level 102, and the mouth of the water inlet 103 is passed into the upstream water level 102 water; the water outlet is located at the downstream water level, including a flexible pipe, a vertical pipe and a floating body; The straight pipe is connected, and the vertical pipe body is fixedly connected with the floating body.

[0032] The upstream water level 102 is transported to at least one downstream water level through at least one...

Embodiment 2

[0038] Embodiment 2, with reference to figure 2 , the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that the water inlet of this embodiment includes a hose, an inverted U-shaped pipe and a floating body, which are respectively named as the water inlet hose 213 and the inverted U-shaped pipe 211 and the water inlet floating body 212; one end of the water inlet hose 213 is connected to the water delivery pipe 104, and the other end is connected to one end of the inverted U-shaped pipe 211, and the other end of the inverted U-shaped pipe 211 extends into the water at a predetermined depth from the upstream water level 102 water surface , the body of the inverted U-shaped pipe 211 is fixedly connected with the floating body 212 at the water inlet; The water inlet hose 213 is always in a loose state. The actual length of the water inlet hose 213 is recommended to be greater than the straight line length from the mouth ...

Embodiment 3

[0040] Embodiment 3, with reference to image 3 , the structure and principle of this embodiment and embodiment 1 are basically the same, the difference is: the vertical pipe of the present embodiment extends above the floating body 413 and includes an outer pipe 313 and an inner pipe 311, and the inner pipe 311 can be made in the outer pipe 313 Sliding up and down, the inner tube 311 and the outer tube 313 junction use a water-sealing material 312 such as a silicone tape or a plastic film to seal the water flow and brake the inner tube 311 to slide up and down arbitrarily by resistance.

[0041] Changing the length of the overlapping portion of the outer pipe 313 and the inner pipe 311 can easily change the height of the vertical pipe floating above the water surface of the downstream water level 412, and indirectly obtain the required height of the downstream water level 412.

Abstract

Provided is an inverted siphon water delivery device whose water outlet pipe mouth surfaces. An inverted siphon is arranged between a water supply upstream water level and downstream water levels of downstream water consumption devices. The device is characterized in that the inverted siphon comprises a water inlet end, a water pipe, and a water outlet end. The water pipe is connected with the water inlet end and the water outlet end. The water inlet end is on the upstream water level. A water outlet end pipe mouth is communicated with water of the upstream water level. The water outlet end is on the downstream water level. The water outlet end comprises a flexible pipe, a vertical pipe, and a floating body. One end of the flexible pipe is connected with the water pipe, and the other end is connected with the vertical pipe. The pipe body of the vertical pipe is fixedly connected with the floating body. The upper end of the vertical pipe extends out of water surface by set height, and the set height is water head of upstream and downstream. The inverted siphon can be provided with a plurality of water outlet ends. Through an upstream water level, the device can obtain multiple downstream water levels. The device is automatic and sensitive without errors. Since the pipe mouth of the upper end of the vertical pipe extends out of water surface, the upstream and downstream water level would not flow back, and the device has effects of a check valve.

Description

technical field [0001] The invention relates to a water delivery device, in particular to an inverted siphon water delivery device with a water outlet emerging from the water surface. The function of check valve. Background technique [0002] In experimental potted plants, soilless culture and nursery pond culture, a water level control device is often used to provide an upstream water level for water supply, and then connect multiple downstream water levels for water consumption through multiple inverted siphons, but there are two problems in actual practice: [0003] 1. One upstream water level, although multiple downstream water levels can be supplied simultaneously through multiple pipelines, these downstream water levels can only be at the same water level as the upstream water level. Due to different treatment or topography, the water level requirements of different downstream water levels cannot always be consistent. In such cases, another water level control system ...
