Siphon rain and sewage diversion device

Abstract

The utility model provides a siphon rainwater and sewage diversion device. A water mixing bin (Q1) and a rainwater bin (Q2) are communicated through a siphon (HX) arranged on a partition plate (G); the siphon is arranged on the partition plate, under the condition that the sewage outlet is closed, in the process that the liquid level of the water mixing bin rises to the position of the hook line, rainwater only enters but does not flow out, and therefore the liquid level of the water mixing bin can reach the position of the hook line in an accelerated mode; when the liquid level descends from the hook line to the blow-off line, the liquid level in the siphon rises to the position of the siphon line to form siphon, the liquid level enters and exits at the same time in the process of rising from the position of the outflow line to the position of the siphon line, and the stroke time is short and is not within the range of an external flow mixing pipe, so that the amount of needed rainwater is small, the siphon is easy to form, and after the siphon is formed, the siphon is easy to form. The flow rate is larger than the flow rate of self-flowing of the through hole with the same diameter, so that the liquid level can be quickly reduced to be below a pollution discharge line; not only can the accuracy of rainwater and sewage diversion be greatly improved, but also the failure rate of equipment can be reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage diversion devices, in particular to a siphon rainwater and sewage diversion device. Background Art

[0002] In the prior art, the patent application with the publication number CN 220704714 U discloses a driving mechanism and a rainwater and sewage diversion device, in which the technical solution provided is:

[0003] When it rains, as rainwater continues to enter, the liquid level inside the mixing tank drives the reset part to rise continuously, and drives the connecting arm mechanism to re-enter the first limit position but does not play a limiting role. The driving part still keeps falling to block the sewage outlet, and the current liquid level inside the mixing tank is named the hook line L1 position;

[0004] After the rain stops, the rainwater inside the mixed water tank flows through the through hole K on the partition to the rainwater tank and is discharged through the rainwater outlet. When the liquid level in the mixed water tank is lower than the preset position, the reset member moves down and drives the connecting arm mechanism to the first limit part position and plays a limiting role, and limits the first limit part through the second limit part. The reset member falls and pulls up the driving member to open the sewage outlet, and the remaining water in the mixed flow tank is discharged through the sewage outlet. The current liquid level inside the mixed water tank is named as the sewage discharge line L2 position;

[0005] When it rains for the first time, if the driving member falls and blocks the sewage outlet, if you want to pull up the driving member after the rain stops to reopen the sewage outlet, the water level in the mixing tank must rise above the hook line when it rains, and after the rain stops, the liquid level in the mixing tank must drop below the sewage line. Therefore, the relative positions of the through hole on the partition, the sewage line, and the hook line are as follows: Figure 1 As shown;

[0006] In actual use, it was found that the process of opening holes in the partition to allow rainwater inside the mixing tank to flow to the rainwater tank has the following disadvantages:

[0007] 1) When it rains, when the driving part falls and blocks the sewage outlet, the liquid level in the mixing tank wants to rise to the hook line. This is done while the mixed inlet is feeding water into the mixing tank and the holes on the partition are draining water into the rainwater tank. Moreover, when the mixed inlet is connected to a longer mixing pipe T, the process will be even longer. Figure 2 As shown; if the rainfall is small or the rainfall time is short, the liquid level cannot rise above the hook line, and the sewage outlet cannot be opened after the rain stops, causing a large amount of sewage to enter the rainwater pipe network;

[0008] 2) Even if the liquid level in the mixing water tank successfully rises above the hook line when it rains, after the rain stops, the liquid level in the mixing water tank needs to drop from the hook line to the sewage line before the reset part can be lowered and the drive part can be pulled up to reopen the sewage outlet. At this time, the liquid level drop process is completed by the through hole on the partition to allow the rainwater in the mixing water tank to flow to the rainwater tank. During this process, the mixed water inlet may intermittently enter the sewage, making it impossible for the liquid level to drop quickly to the sewage line, resulting in a large amount of sewage entering the rainwater pipe network.

[0009] In summary, when the liquid level in the mixed water tank rises to the hook line, it is hoped that less rainwater will flow from the through hole on the partition to the rainwater tank, or even no rainwater will flow from the through hole on the partition to the rainwater tank, so that the hook can be quickly and smoothly (i.e. the connecting arm mechanism enters the first limit part). When the liquid level drops to the sewage discharge line, it is hoped that the through hole can maintain a certain flow rate, so that the sewage outlet can be opened smoothly. However, it is impossible to achieve smooth progress of both processes by changing the diameter and position of the through hole, and a through hole with a diameter that is too small is also prone to blockage.

[0010] Therefore, there is an urgent need to provide an effective technical solution to solve the defects and shortcomings in the above-mentioned prior art. Utility Model Content

[0038] [First embodiment]

[0039] like Figure 4-5 The siphon rainwater-sewage diversion device provided by the first embodiment of the utility model is shown, including a box body H, on which a mixed inlet M, a rainwater inlet P, a rainwater outlet Y and a sewage outlet W are respectively opened. The mixed inlet M can be externally connected to a mixed flow pipe T as needed. A driving structure is installed inside the box body H, and the driving structure includes a bracket assembly 1. One side of the bracket assembly 1 is connected to a driving member 2 located at the top of the sewage outlet W through a connecting rod mechanism 4. The driving member 2 can be set to a cover body shape to facilitate the opening and closing of the sewage outlet W through its lifting. The other side is connected to a reset member 3 that can rise and fall synchronously with the liquid level inside the box through a connecting arm mechanism 5. The reset member 3 can It is set to a float shape to facilitate the synchronous rise and fall with the liquid level to realize the driving of the driving member 2; the bracket assembly 1 is also connected to a limit rod 7 and a driving assembly 6 that cooperates with the limit rod 7, the rainwater pipe P1 passes through the rainwater inlet P into the interior of the box H and is located at the top of the driving assembly 6, a first limit portion A is formed between the connecting arm mechanism 5 and the connecting rod mechanism 4, and a second limit portion B is formed between the limit rod 7 and the connecting arm mechanism 5, and rainwater entering the interior of the driving assembly 6 can help the limit rod 7 to disengage from the second limit portion B, and the second limit portion B can also realize the limiting effect on the first limit portion A, and the interior of the box H is divided into a mixing water tank Q1 and a rainwater tank Q2 by a partition G.

[0040] In the rain, when the connecting arm mechanism 5 re-enters the first limit portion A position and the driving member 2 still keeps falling to block the sewage outlet W, the liquid level in the mixing tank Q1 at this time is recorded as the hook line position;

[0041] After the rain stops, the reset member 3 drops down and pulls up the drive member 2 to open the sewage outlet W. The liquid level in the mixing tank Q1 at this time is recorded as the sewage discharge line position; and the hook line position is higher than the sewage discharge line position.

[0042] The above are all prior arts in this field. For details, please refer to the contents disclosed in the patent application with publication number CN 220704714 U, which will not be repeated here.

[0043] The outstanding contribution of this embodiment over the prior art is: Figure 3 As shown, the mixing water tank Q1 and the rainwater tank Q2 are connected by a siphon HX arranged on the partition G. By arranging the siphon on the partition, when the sewage outlet is closed, the liquid level in the mixing water tank Q1 can be accelerated to reach the hook line position; and when the sewage outlet is opened, the liquid level can be quickly lowered to below the sewage discharge line.

[0044] Its specific structure is as follows Figure 3 As shown, the siphon tube HX includes a sleeve HX1 fixed inside the partition G. Correspondingly, a through hole for passing and fixing the sleeve HX1 is opened on the top of the partition G, thereby facilitating the stable installation and fixation of the siphon tube HX inside the box body H.

[0045] One end of the sleeve HX1 extending into the mixing water tank Q1 is connected to the inlet pipe HX2, and one end of the sleeve HX1 extending into the rainwater tank Q2 is connected to the outlet pipe HX3. In the present embodiment, the sleeve HX1 is configured as a U-shaped tube with the opening facing downward, the axial directions of the inlet pipe HX2 and the outlet pipe HX3 are arranged in the vertical direction, and the bottom end of the inlet pipe HX2 is higher than the bottom end of the outlet pipe HX3, so as to achieve a siphon effect.

[0046] like Figure 3 As shown, the top of the inner wall of the casing HX1 is the siphon line position, and the siphon line position is higher than the hook line position. When the liquid level entering the siphon pipe HX rises to the siphon line position, a siphon is formed. The bottom of the inner wall of the casing HX1 is the outlet flow line position, and the outlet flow line position is higher than the hook line position but lower than the siphon line position. The liquid level entering the siphon pipe HX rises from the outlet flow line position to the siphon line position. Only in the process of the liquid level entering the siphon pipe HX rising from the outlet flow line position to the siphon line position can the effect of water entering from the mixed inlet M while water outflowing from the siphon pipe HX be achieved.

[0047] As a preferred embodiment of the present invention, the siphon diameter of the siphon tube HX can be set as needed. For example, the siphon diameter can be appropriately increased to reduce the probability of blockage, which can not only greatly improve the accuracy of rainwater and sewage diversion, but also reduce the failure rate of the equipment.

[0048] The specific working process of this embodiment is as follows:

[0049] When the sewage outlet is closed, during the process of the liquid level in the mixing tank rising to the hook line, rainwater only enters but does not flow out, so it will definitely reach the hook line position.

[0050] When the liquid level needs to drop from the hook line to the sewage line, the liquid level needs to rise to the siphon line first to form a siphon. The liquid level can only be in and out at the same time during the process of rising from the outlet line to the siphon line. However, this stroke is short and is not within the range of the external mixed flow pipe. Therefore, the required amount of rainwater is small and the siphon is easily formed. After the siphon is formed, the flow rate is larger than the flow rate of gravity of the same diameter through-hole, and the liquid level can be quickly lowered to below the sewage line.

[0051] In addition, the diameter of the siphon pipe can be set as needed. For example, the diameter of the siphon pipe can be appropriately increased to reduce the probability of blockage. This can not only greatly improve the accuracy of rainwater and sewage diversion, but also reduce the failure rate of equipment.

[0052] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
