[0033] The present application will be further described below in combination with the drawings and specific embodiments. The present application will be further described below in combination with the drawings and specific embodiments.

[0034] See Figure 1 , showing a schematic diagram of the use of the siphon drainage device for slopes of the present invention. Figure 2 , shows the schematic diagram of the rainwater bucket and the second siphon pipe structure of the siphon drainage device for slopes of the present invention. Figure 1 and Figure 2 , a siphon drainage device for slope and a method of using the same are described in the present invention.

[0035] like Figure 1 and Figure 2 As shown, a siphon drainage device for a slope of the present invention is used to drain water in a sump 2 on a slope platform into a drainage pit 6. The siphon drainage device includes: a first siphon pipe 5 fixed to the slope 1, the lower end of the first siphon pipe 5 being located in the drainage pit 6, and the upper end being located in the sump 2; a rain gutter 3 provided on the slope 1; a second siphon pipe 4, the upper end of the second siphon pipe 4 extending into the rain gutter 3, and the lower end connected to the first siphon pipe 5. When the water in the rain gutter 3 submerges the second siphon pipe 4, the water in the rain gutter 3 flows into the first siphon pipe 5 through the second siphon pipe 4, and continues to flow downward into the drainage pit 6 below. When the water flows in the first siphon pipe 5, a negative pressure is formed in the upper half of the first siphon pipe 5, thereby sucking the water in the sump 2 into the first siphon pipe 5 and discharging it into the drainage pit 6.

[0036] Specifically, the first siphon pipe 5 includes an inclined section and a horizontal section, the rain gutter 3 is arranged on the inclined section of the first siphon pipe 5 , and the lower end of the second siphon pipe 4 is connected to the inclined section of the first siphon pipe 5 .

[0037] like Figure 3 and Figure 4 As shown, in a specific embodiment, the rain gutter 3 includes a rain gutter body 32 and two supporting mechanisms 31. The two supporting mechanisms 31 are fixed on the slope 1 at intervals, and the rain gutter body 32 is installed on the supporting mechanism 31 with an adjustable angle so that the rain gutter 3 can adapt to slopes 1 with different inclination angles.

[0038] Specifically, the lower end of the first siphon pipe 5 is higher than the height of the drainage pit 6 , thereby preventing the water in the drainage pit 6 from clogging the lower end of the first siphon pipe 5 .

[0039] In a specific embodiment, the support mechanism 31 includes: a fixed plate 311, fixed on the slope 1; a support frame 312, fixedly mounted on the rain gutter body 32, and a support rod 313 is fixed to the lower end of the support frame 312, and the support rod 313 is hinged to the lower end of the fixed plate 311; an adjusting rod 314, one end of which is hinged to the upper end of the fixed plate 311, and the other end is movably connected to the upper end of the support frame 312, and the angle between the support frame 312 and the fixed plate 311 is adjusted by adjusting the connection position of the adjusting rod 314 and the support frame 312.

[0040] like Figure 5 As shown, in a specific embodiment, two clamping plates 315 are fixed at intervals on the upper end of the support frame 312, and the adjusting rod 314 is arranged between the two clamping plates 315. It also includes a limiting rod 316, which passes through the two clamping plates 315 and can be adjusted up and down so that the limiting rod 316 fixes the adjusting rod 314 between the two clamping plates 315.

[0041] Specifically, the limiting rod 316 is a screw with nuts at both ends. Tightening the nuts secures the screw to the clamping plates 315, thereby pressing down the adjustment rod 314 and securing it between the two clamping plates 315. The threads at both ends of the screw rotate in opposite directions, resulting in different rotation directions for the two nuts. The surface of the adjustment rod 314 is textured to increase friction with the screw 316.

[0042] In a specific embodiment, a slot is provided on one side of the fixing plate 311 , and the slot is used to be fixed on the lattice beam of the slope 1 .

[0043] In a specific embodiment, the second siphon tube 4 extends into the rain gutter 3 by passing through one side of the rain gutter 3, so that the rainwater in the rain gutter 3 submerges the second siphon tube 4 before overflowing.

[0044] Specifically, the cross-section of the rain gutter body 32 is triangular, and is made by splicing two triangular plates and two rectangular plates. The two rectangular plates are connected between the two triangular plates, and the lower ends of the two rectangular plates are connected so that the opening of the rain gutter body 32 is upward, thereby forming a container that can hold water.

[0045] Preferably, the two triangular plates are glass plates, so that personnel can observe the water level in the rain gutter body 32 through the glass plates on both sides. A drainage hole is formed at the bottom of the rain gutter body 32, and a valve is provided in the drainage hole. By opening the valve, the water in the rain gutter body 32 is completely drained from the drainage hole, thereby facilitating cleaning of the rain gutter body 32.

[0046] The application also provides a method for using the siphon drainage device for the slope, which specifically comprises the following steps: providing the siphon drainage device as described above; fixing the first siphon pipe 5 on the slope 1, and extending the upper end of the first siphon pipe 5 into the water collecting pit 2 and extending the lower end of the first siphon pipe 5 into the drainage pit 6; fixing the rainwater head 3 on the slope 1, and extending the upper end of the second siphon pipe 4 into the rainwater head 3 and connecting the lower end of the second siphon pipe 4 to the first siphon pipe 5.

[0047] In a specific embodiment, the rainwater head 3 comprises a support mechanism 31 and a rainwater head body 32, and the angle between the rainwater head body 32 and the support mechanism 31 can be adjusted; when the rainwater head 3 is installed, the support mechanism 31 is fixed on the slope 1, and the angle between the rainwater head body 32 and the support mechanism 31 is adjusted so that the opening of the rainwater head body 32 faces upward and is kept horizontal.

[0048] The use process and working principle of the siphon drainage device for the slope will be described in detail below.

[0049] The first siphon pipe 5 is fixed on the slope 1, and the upper end of the first siphon pipe 5 is extended into the water collecting pit 2 and the lower end of the first siphon pipe 5 is located above the drainage pit 6.

[0050] The clamping groove of the fixing plate 311 is clamped on the lattice beam of the slope 1, then the rainwater head body 32 is rotated so that the opening of the rainwater head 32 faces upward and is kept horizontal, then the limiting rod 316 is moved downward so that the limiting rod 316 presses the adjusting rod 314, and the nuts at the two ends of the limiting rod 316 are tightened to fix the limiting rod 316 and the adjusting rod 314.

[0051] The upper end of the second siphon pipe 4 is extended through one side of the rainwater head body 32 and into the rainwater head body 32, and the lower end of the second siphon pipe 4 is communicated with the first siphon pipe 5.

[0052] Working principle: when in use, rainwater falls into the rainwater head body 32 and the water collecting pit 2, and the water level in the rainwater head body 32 gradually rises; when the water submerges the second siphon pipe 4, the water in the rainwater head body 32 flows into the first siphon pipe 5 through the second siphon pipe 4, and flows downward to the drainage pit 6 under the action of gravity. When the water flows in the first siphon pipe 5, the upper half of the first siphon pipe 5 forms a negative pressure, so that the water in the water collecting pit 2 flows into the first siphon pipe 5 and further flows into the drainage pit 6.

[0053] When the water level in the rainwater head body 32 drops to the height of the inlet of the upper end of the second siphon pipe 4, the water in the rainwater head body 32 stops flowing into the second siphon pipe 4. When the water level in the water collecting pit 2 drops to the height of the inlet of the upper end of the first siphon pipe 5, the water in the water collecting pit 2 stops flowing into the first siphon pipe 5.

[0054] The application is described in detail above with reference to the drawings. Those skilled in the art can make various changes to the application according to the above description. Therefore, some details in the embodiments should not be regarded as limiting the application, and the scope of protection of the application is defined by the appended claims.
