[0024] The present invention is further described in detail below with reference to the embodiments.

[0025] The specific embodiment of the underground siphon drainage device provided by the utility model is as follows:

[0026] See also Figure 1-5 The underground siphon drainage device includes a drainage ditch 1 for collecting water, and the drainage ditch 1 is connected to the water storage pool 2; the drainage ditch 1 is arranged at the lower side of the water sprinkling gap belt to fully collect the sprinkling water discharged from the gap, and the water flows into the water pool 2 through the drainage ditch 1 for temporary storage.

[0027] A siphon tube 3 is set up between the pool 2 and the drainage well 13. The water inlet end of the siphon tube 3 is located at the lower part of the pool 2. A filter screen is set at the water inlet end of the siphon tube 3 to prevent large-volume impurities from entering the siphon tube 3; the siphon tube 3 bypasses the upper side of the pool 2 and bends downward, and the water outlet end extends into the drainage well 13; the siphon tube 3 is filled with water, and the water outlet end of the siphon tube 3 is lower than its water inlet end. Under the action of the siphon pressure difference, water passes through the siphon tube 3 and enters the drainage well 13.

[0028] A valve 4 is provided on the siphon pipe 3. Specifically, the valve 4 is arranged at a lower position of the siphon pipe 3, close to the wellhead of the drain well 13; the valve 4 includes a valve plate 41 and an elastic member, and the elastic member enables the valve plate 41 to close the valve 4 channel; the valve body of the valve 4 has a sealing ring facing the valve plate 41 side, and the structure of the valve 4 and the valve plate 41 is similar to that of the plug-in valve. Specifically, the valve plate 41 is plugged into the valve body of the valve 4; an external frame 42 is provided on the outside of the valve body of the valve 4, and the elastic member is a spring 43. Two springs 43 are provided, and the spring 43 is connected between the outside of the valve plate 41 and the external frame 42. When not subject to external force, the spring 43 enables the valve plate 41 to completely enter the valve body of the valve 4, closing the valve 4 channel.

[0029] A floating body 5 is provided in the pool 2, which rises and falls vertically with the water surface. The floating body 5 is a hollow annular structure. A vertical column 7 is provided in the pool 2. The lower end of the column 7 is pre-buried in the bottom wall of the pool 2, and a reinforcement bracket is connected between the upper end of the column 7 and the upper end of the pool 2. The floating body 5 surrounds the column 7 and fits on the outside of the column 7 and moves vertically along the column 7. The column 7 provides guidance for the vertical movement of the floating body 5.

[0030] A traction rope 6 connects the floating body 5 to the valve plate 41. Rope loops 8 are provided on the upper side and inner bottom of the pool 2. The traction rope 6 passes through the two loops 8 in sequence and connects to the underside of the floating body 5. The traction rope 6 is a non-elastic steel wire rope, which is strong and can be moved through the loops 8. The traction rope 6 passes through the outer frame 42. In other embodiments, a fixed pulley can be provided in place of the loops 8 to reduce friction.

[0031] When the amount of water collected by gutter 1 during a certain period is high and the water level in pool 2 rises, float 5 rises, using pull rope 6 to cause valve plate 41 to gradually open and widen valve 4, overcoming the elastic force of the spring. The higher the water level rises, the wider valve 4 opens, increasing the amount of water discharged and causing the water level to drop. As the water level drops, float 5 descends, loosening pull rope 6 a bit, and spring 43 gradually lowers valve plate 41, thus maintaining a stable water level. If the amount of water collected by gutter 1 during a certain period is too low, float 5 descends to the bottom of pool 2 until the water level in pool 2 drops too low, causing valve plate 41 to close valve 4. This maintains water upstream of valve 4 in siphon 3, preventing subsequent flow interruption.

[0032] Because the depth of the pool 2 is generally much greater than the inner diameter of the valve 4 passage and the siphon 3, a deceleration assembly is provided in this embodiment to ensure that the floating body 5 and the valve plate 41 move synchronously, but at different speeds. In this embodiment, the traction rope 6 includes a first rope member 61 connected to the floating body 5 and a second rope member 62 connected to the valve plate 41. The first rope member 61 and the second rope member 62 are connected by the deceleration assembly.

[0033] The reduction assembly includes a rotatably mounted first drum 9 and a second drum 10. A mounting bracket 12 is provided on the outside of the pool 2. The first drum 9 and the second drum 10 both include a central axis, each of which is rotatably connected to the mounting bracket 12. The outer diameter of the rope-winding portion of the first drum 9 is four times greater than the outer diameter of the rope-winding portion of the second drum 10. A first rope 61 is wound around the outside of the first drum 9, and a second rope 62 is wound around the outside of the second drum 10. Meshing gears 11 are connected to one end of the first drum 9 and the second drum 10. There are two identical gears 11, and their transmission ratio is one. Thus, when subjected to the force of the ropes, the first drum 9 and the second drum 10 rotate at the same speed. During the same rotation, the length of the first rope 61 wound or released by the first drum 9 is greater than the length of the second rope 62 wound or released by the second drum 10, thereby achieving synchronous but different-speed movement of the valve plate 41 following the floating body 5.

[0034] like Figure 4 and Figure 5 As shown, if the floating body 5 descends, driving the first drum 9 to rotate two circles, the first rope 61 is released two circles; the second drum 10 rotates two circles synchronously, but the second drum 10 winds two circles of the second rope 62. The second rope 62 causes the valve plate 41 to overcome the elastic force of the spring 43 and rise to a height of two circles of the second rope length 62. The rising distance of the valve plate 41 is less than the descending distance of the floating body 5.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
