DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a landscaping drainage system, comprising a sewage well 1 and a well cover 2 arranged on the sewage well 1, and also comprising a drainage channel pipe 3 used in conjunction with the sewage well 1 and used for drainage, wherein the sewage well 1 is provided with a drainage structure for discharging rainwater therein; The drainage structure includes a siphon pipe 4 disposed between the sewage well 1 and the drainage channel pipe 3. The siphon pipe 4 is in a U-shaped structure and its two ends are respectively connected to the gas between the sewage well 1 and the drainage channel pipe 3. The end of the siphon pipe 4 facing the sewage well 1 is located at the bottom of the sewage well 1. The drainage structure also includes a plurality of groups of special-shaped positioning bases 23 fixedly connected to the inner wall of the sewage well 1, the sewage well 1 includes an integrally formed transverse partition 101 and a water outlet 11 is provided at the position corresponding to the special-shaped positioning base 23, and a water response component for sensing a water source is provided on the water outlet 11; An upper channel pipe 12 and a lower channel pipe 13 are provided on the special-shaped positioning base 23 , and a rainwater channel for rainwater to flow is formed therebetween. A water-blocking component for blocking the rainwater channel is provided between the upper channel pipe 12 and the lower channel pipe 13 .

[0022] like Figure 1 and Figure 2 As shown, in the landscaping drainage, rainwater flows into the sewage well 1 through the manhole cover 2, wherein the manhole cover 2 can effectively prevent leaves, garbage, stones and other debris from entering the sewage well 1, prevent the drainage system from being blocked, and ensure that rainwater can be discharged smoothly. The manhole cover 2 has good load-bearing capacity, can withstand the weight of pedestrians, vehicles, etc., is not easy to be damaged, and has a long service life.

[0023] At the same time, after passing through the manhole cover 2, the rainwater passes through the water-response component. After passing through the water-response component, the rainwater can drive the water-blocking component to operate. When the water-blocking component is operating, negative pressure suction can be generated at the position of the siphon pipe 4. At the same time, after the rainwater enters the sewage well 1, the rainwater temporarily stays therein. The end of the siphon pipe 4 facing the sewage well 1 is at the bottom position of the sewage well 1, that is, the water inlet end of the siphon pipe 4 faces the bottom plate position of the sewage well 1. Therefore, the water inlet end of the siphon pipe 4 is immersed in the rainwater in the sewage well 1.

[0024] Therefore, a negative pressure phenomenon is driven to occur in the siphon pipe 4 through the water-blocking component. When an air pressure difference occurs in the siphon pipe 4, rainwater in the sewage well 1 is sucked into the siphon pipe 4 and flows freely in the siphon pipe 4, thereby generating a siphon effect in the sewage well 1 and the drainage channel pipe 3, thereby driving the rainwater in the sewage well 1 to actively flow into the drainage channel pipe 3 through the siphon pipe 4.

[0025] Among them, the rainwater in the sewage well 1 is actively driven to be discharged through the siphon effect, so it will not be affected by the relative position of the drainage channel pipe 3 and the sewage well 1. Compared with the traditional gravity drainage, its gravity drainage may be affected by the terrain undulation or the angle of the pipe, but under the siphon effect, the drainage channel pipe 3 can be buried at a shallow depth, and it can still ensure that the rainwater in the sewage well 1 can be quickly discharged.

[0026] Therefore, during the actual construction of the drainage system, the burial depth of the drainage channel pipe 3 does not need to be deeper than the sewage well 1. Therefore, during the laying process of the drainage channel pipe 3, it is possible to avoid underground obstacles such as rock layers, other pipes and cables, thereby reducing the difficulty of construction. Moreover, the shallower the burial operation, the less difficult the construction, and the labor cost and machinery cost will be reduced accordingly, thereby significantly reducing the construction cost.

[0027] In one of the more preferred embodiments, the water blocking assembly includes a plurality of groups of triangular sealing blocks 16 that are synchronously and horizontally swung and are arranged in a special-shaped positioning base 23, and the plurality of groups of triangular sealing blocks 16 jointly block the rainwater channel between the upper channel pipe 12 and the lower channel pipe 13, and the plurality of groups of triangular sealing blocks 16 are all provided with air holes 29; The siphon pipe 4 is provided with a plurality of venturi tubes 26 fixedly passing through. The venturi tubes 26 are fixedly connected to the triangular sealing block 16 and are in gas communication with the air holes 29. The siphon pipe 4 is provided with a one-way sealing component for sealing itself.

[0028] The one-way sealing assembly includes a radial frame 27 fixedly connected to the inner wall of the siphon pipe 4 , on which two groups of semicircular air blocking plates 28 symmetrically arranged are arranged to rotate on a fixed axis, and the semicircular air blocking plates 28 are in sliding contact with the inner wall of the siphon pipe 4 .

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, multiple groups of triangular sealing blocks 16 jointly block the upper channel pipe 12 and the lower channel pipe 13. In the initial state, the multiple groups of triangular sealing blocks 16 completely block the rainwater channel. Although the manhole cover 2 can intercept most of the debris such as dead branches and leaves, there will still be some leaves, mud, garbage and other materials accumulated in the sewage well 1. These substances are decomposed by microorganisms in the sewage well 1 to produce volatile gases, such as ammonia and other gases, which then emit odors. Therefore, the multiple groups of triangular sealing blocks 16 in the initial state can completely block the rainwater channel, thereby preventing the odor in the sewage well 1 from flowing into the outside air through the upper channel pipe 12 and the lower channel pipe 13.

[0030] At the same time, when the rainwater falling into the sewage well 1 drives the water-resisting components to operate, the multiple groups of triangular sealing blocks 16 are deflected, so that the rainwater can accumulate at the bottom of the sewage well 1 through the rainwater channel, and a negative pressure phenomenon is generated in the siphon pipe 4 through the water-resisting components, thereby promoting a siphon effect between the sewage well 1 and the drainage channel pipe 3, so as to ensure that the rainwater deposited in the sewage well 1 is automatically discharged into the drainage channel pipe 3.

[0031] Among them, two groups of semicircular air barriers 28 are provided in the siphon pipe 4. The two groups of semicircular air barriers 28 jointly block the interface position between the siphon pipe 4 and the drainage channel pipe 3 in the initial state, and under the restriction of the radial frame 27, the semicircular air barrier 28 can only deflect toward the drainage channel pipe 3. When a negative pressure phenomenon is driven in the siphon pipe 4 by the Venturi tube 26, the semicircular air barrier 28 will not deflect. However, when the siphon phenomenon drives rainwater to flow from the sewage well 1 to the drainage channel pipe 3, the semicircular air barrier 28 will deflect under the flow force of rainwater to open the channel between the siphon pipe 4 and the drainage channel pipe 3, ensuring that rainwater can flow into the drainage channel pipe 3 through the siphon pipe 4.

[0032] At the same time, when rainwater passes through multiple groups of Venturi tubes 26, since the size of the channel for rainwater circulation between the Venturi tubes 26 is smaller than the size of the rainwater channel between the upper channel pipe 12 and the lower channel pipe 13, according to the Venturi effect, the Venturi effect is expressed as follows: when the fluid passes through a tightened channel, the flow rate will increase, and its size is inversely proportional to the cross-section of the tightening point. Therefore, when rainwater flows through the position of the Venturi tube 26, its flow rate at this position increases, and under the Bernoulli effect, low pressure will be generated near the highly flowing fluid. Therefore, low pressure is generated at the position of the Venturi tube 26, and the gas between the Venturi tube 26 and the pore 29 is the same. Therefore, when rainwater passes through the position of the Venturi tube 26, it can cause a low pressure phenomenon in the siphon pipe 4 through the Venturi tube 26 to promote the generation of a siphon effect.

[0033] It should be noted that a torsion spring is provided between the semicircular air blocking sheet 28 and the radial frame 27 to restore the radial frame 27 to its initial state. The torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure.

[0034] On the basis of the embodiment of the water blocking component, the special-shaped positioning base 23 is fixedly connected with a blocking disc 15, and a positioning disc 14 that can rotate freely in the horizontal direction is provided above the blocking disc 15. The special-shaped positioning base 23 is fixedly connected with an inwardly extending ring 10 toward the positioning disc 14, and the inwardly extending ring 10 is provided with an annular groove for the positioning disc 14 to slide. The triangular sealing block 16 includes an integrally formed lower portion 17 below, a hexagonal slide groove 18 for the lower portion 17 to slide horizontally is provided on the blocking disc 15, a limiting pin 19 is fixedly connected to the upper portion of the triangular sealing block 16, and a limiting groove 20 for the limiting pin 19 to slide is provided on the positioning disc 14; The outer circumference of the positioning disc 14 is fixedly connected with an outwardly extending bracket rod 21 , and the special-shaped positioning base 23 is provided with an arc-shaped clearance groove 22 for the outwardly extending bracket rod 21 to slide through, and the upper surface of the positioning disc 14 is in sliding contact with the upper channel pipe 12 .

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, when the positioning disc 14 rotates a certain angle in the horizontal direction, it can drive multiple groups of limit pins 19 and the triangular sealing block 16 on the limit pins 19 to deflect in the horizontal direction through the limit groove 20, wherein the lowering portion 17 arranged at the bottom of the triangular sealing block 16 is slidably connected to the positioning disc 14 through the hexagonal slide groove 18. Therefore, the stability of the triangular sealing block 16 during deflection can be guaranteed by the hexagonal slide groove 18.

[0036] At the same time, when multiple groups of triangular sealing blocks 16 are deflected synchronously, the upper channel pipe 12 and the lower channel pipe 13 can be driven to be unobstructed, thereby ensuring that rainwater can flow through the upper channel pipe 12, through the Venturi tube 26, and accumulate at the bottom of the sewage well 1 through the lower channel pipe 13. When rainwater passes through the Venturi tube 26, the size of its flow channel becomes smaller. Under the Venturi effect and Bernoulli effect, the Venturi tube 26 causes a low pressure phenomenon to be generated in the siphon pipe 4, so that a siphon effect is generated between the sewage well 1 and the drainage channel pipe 3.

[0037] Furthermore, the water-resisting component includes a rain-resisting frame 5 arranged above the diaphragm 101, a central column 7 is fixedly connected to the bottom of the rain-resisting frame 5, and a ring frame 8 is fixedly connected to the position of the central column 7 on the inner wall of the sewage well 1, the central column 7 radially penetrates the diaphragm 101, and a receiving groove for the central column 7 to slide vertically is opened on the ring frame 8; A plurality of groups of return springs 9 are arranged in the receiving groove, and both ends of the plurality of groups of return springs 9 are fixedly connected to the center column 7 and the inner wall of the ring frame 8 respectively.

[0038] A freely deflectable connecting rod 24 is provided between the central column 7 and the extended bracket rod 21, and a group of ball head seats 25 are fixedly connected to the corresponding end positions of the connecting rod 24. The end of the connecting rod 24 includes an integrally formed ball head end, and both groups of ball head seats 25 are provided with ball head chambers for the ball head ends to slide.

[0039] like Figure 2 and Figure 6 As shown, when rainwater falls through the manhole cover 2, it can first fall into the rain response frame 5. As the amount of rainwater in the rain response frame 5 gradually increases, the rain response frame 5 moves downward under the gravity of the rainwater, thereby driving the center column 7 fixed thereon to move downward, thereby squeezing the reset spring 9 set under the center column 7 and driving the reset spring 9 to undergo compression deformation.

[0040] Among them, the sewage well 1 is fixedly connected with a ring frame 8 at the position corresponding to the center column 7, and the center column 7 and the ring frame 8 are slidably connected. Therefore, the center column 7 is jointly restricted by the ring frame 8 and the cross partition 101 to ensure the stability of the center column 7 when the height changes. At the same time, a connecting rod 24 is provided between the center column 7 and the extended bracket rod 21 to drive the extended bracket rod 21 to deflect. When the horizontal height of the center column 7 changes, the extended bracket rod 21 can be driven to deflect through the connecting rod 24, and the deflection of the extended bracket rod 21 can drive the positioning disk 14 to rotate to drive multiple groups of triangular sealing blocks 16 to deflect synchronously.

[0041] At the same time, when the outward-extending frame rod 21 is deflected, its horizontal lateral position and horizontal longitudinal position will change synchronously, but the center column 7 can only move in the vertical direction. Therefore, an integrally formed ball head end is provided at the end of the connecting rod 24, and a ball head seat 25 for the ball head end to rotate is fixedly provided on the center column 7 and the outward-extending frame rod 21, so as to adapt to the horizontal position change caused by the rotation of the outward-extending frame rod 21, so as to ensure that the height change of the center column 7 can synchronously drive multiple groups of outward-extending frame rods 21 to rotate a certain angle in the horizontal direction.

[0042] Among them, in order to ensure that rainwater can first fall into the rain response frame 5 when entering the sewage well 1, an annular rain guide plate 6 is provided above the rain response frame 5. The annular rain guide plate 6 is fixedly connected to the inner wall of the sewage well 1. The annular rain guide plate 6 is inclined and the inclination direction is toward the side of the rain response frame 5. After the rainwater passes through the well cover 2, the rainwater falls onto the annular rain guide plate 6. Since the outer peripheral height of the annular rain guide plate 6 is higher than the inner peripheral height, and the rain response frame 5 corresponds to the inclined position of the annular rain guide plate 6, the rainwater falling on the annular rain guide plate 6 flows into the rain response frame 5 under the action of gravity.

[0043] Therefore, as the amount of rainwater falling into the rain frame 5 gradually increases, the central column 7 can be driven to move downward gradually, and then the outward bracket rod 21 can be driven to deflect through the connecting rod 24, so as to drive multiple groups of triangular sealing blocks 16 to gradually deflect so that subsequent rainwater can fall into the lower area of ​​the sewage well 1 through the rainwater channel, and after the rainwater passes through the position of the triangular sealing block 16, the water-blocking component is driven to operate, so that a siphon effect is generated between the sewage well 1 and the drainage channel pipe 3 through the siphon pipe 4, so as to enable the rainwater to automatically flow from the sewage well 1 to the drainage channel pipe 3, so as to achieve the purpose of automatic drainage.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
