Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage interception and treatment technology, and in particular to a rainwater and sewage diversion interception well. Background Technology

[0002] In the early stages of rainfall, rainwater dissolves vehicle exhaust and industrial waste gas in the air and washes away asphalt roads, resulting in rainwater containing a large amount of pollutants. If this highly polluted rainwater is directly discharged into rivers, it will cause serious environmental pollution. Therefore, it is necessary to use interception pumping stations to divert and treat the polluted rainwater.

[0003] CN222745259U discloses a smart road intercepting manhole, which includes a plugging mechanism for controlling the discharge of sewage from drain pipe one and drain pipe two, and a sewage discharge mechanism for discharging impurities and sludge from the lower half of the intercepting manhole. Specifically, the plugging mechanism includes a plugging frame installed inside the intercepting manhole, with a plugging gate slidably installed inside the plugging frame. An electric plugging push rod is also installed on the plugging frame, with its telescopic end passing through the plugging frame and fixedly connected to the upper end of the plugging gate. The sewage discharge mechanism includes a sewage pipe installed on the intercepting manhole, with a sewage pump also installed on the sewage pipe.

[0004] Based on the aforementioned publicly available technology, firstly, regarding the sealing mechanism, considering the cylindrical intercepting well, the wall surface of the sealing frame used to fix the sealing mechanism is an arc surface. Therefore, the sealing frame requires customized design and production to adapt to its shape, making it unsuitable for standardized sealing mechanisms. Secondly, regarding the sewage pipe, although the design of the sewage pump can prevent backflow of water from outside the well into the sewage pipe, the added sewage pump requires corresponding control software to adjust its operation, thus increasing the complexity of the control process.

[0005] Therefore, based on the aforementioned problems existing in the current interception wells, it is necessary to further optimize the structure of the interception wells. Utility Model Content

[0020] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] Example 1: Please see Figures 1 to 4 As shown, this embodiment provides a rainwater and sewage diversion interception well, including: a well body 1 and a sewage discharge component and a liquid discharge component disposed inside the well body 1.

[0022] Generally, the well body 1 includes a well body 1 having a hollow cavity and a well cover 2 for covering the upper end of the well body 1; the side wall of the well body 1 is respectively provided with a liquid inlet 3, a liquid outlet and a sewage outlet communicating with the hollow cavity.

[0023] The sewage discharge assembly includes a sewage pipe 5 disposed within a hollow cavity, with one end extending through a sewage outlet to the outside of the well body 1. A one-way valve is provided at the outlet of the sewage pipe 5 extending outside the well body 1. The one-way valve of the sewage pipe 5 allows for one-way flow from the inside of the well body 1 to the outside. A sewage pump 18, which cooperates with the sewage pipe 5, is also provided within the hollow cavity. The one-way valve used in this embodiment can be any one-way valve structure suitable for controlling unidirectional water flow used in water pipes in the prior art. In other words, any one-way valve that can theoretically achieve unidirectional flow of sewage from the inside of the well body 1 to the outside theoretically meets the usage requirements of this embodiment. The specific structure and implementation principle are not limited in this embodiment.

[0024] The drainage assembly includes a drainage pipe 4 that partially penetrates the drainage port and is inserted into the hollow cavity, and a gate disposed at the open end of the drainage pipe 4 within the hollow cavity; the inner wall of the hollow cavity of the well body 1 is integrally provided with a connecting part 6 for connecting the gate, and the end face of the connecting part 6 facing the gate is a flat wall surface.

[0025] More specifically, based on the above structure, the connecting part 6 extends from the bottom end of the well body 1 to the top end of the well body 1 along the depth direction. The gate here can be any mature method from the existing technology; that is, based on the design of the connecting part 6, the gate only needs to use standard parts, without the need for non-standard design and production. Generally, the gate includes a door sleeve 7 fixed to the connecting part 6, forming an opening communicating with the drain pipe 4, and a door plate 8 that slides with the door sleeve 7 to seal the opening. The door sleeve 7 can be directly installed and fixed to the connecting part 6 using fasteners. Of course, from a waterproofing perspective, a sealing structure such as, but not limited to, a sealing ring can be added between the door sleeve 7 and the connecting part 6.

[0026] It is understood that, in this embodiment, the door panel 8 is also connected to a hoisting mechanism 9 for driving the door panel 8 to open and close the opening of the door frame 7. The hoisting mechanism 9 is located on the outside of the hollow cavity of the well body 1 or inside the hollow cavity. The principle by which the hoisting mechanism 9 drives the door panel 8 is a mature method in the prior art, and this embodiment does not impose an absolute limitation on it.

[0027] In summary, for the rainwater and sewage diversion interception well of this embodiment, by integrally providing a connecting part 6 for connecting to a gate on the inner wall of the hollow cavity of the well body 1, and the end face of the connecting part 6 facing the gate being a straight wall surface, the gate used in the rainwater and sewage diversion interception well of this utility model can be a standard structure gate, without the need for non-standard customization. The well body 1 is typically formed by concrete casting; therefore, integrally forming the well body 1 and the connecting part 6 by concrete casting is easier to operate than non-standard customization of the gate. Furthermore, by providing a one-way valve at the pipe opening of the sewage pipe 5 extending outside the well body 1, no additional control program is required, which can meet the sewage discharge requirements while preventing water outside the well body 1 from flowing back into the well body 1 through the sewage pipe 5.

[0028] Example 2: Based on the stormwater and sewage separation interception well of Embodiment 1, the one-way valve used in the stormwater and sewage separation interception well provided in this embodiment generally includes a sealing member 10 hinged to the pipe opening of the sewage pipe 5 extending outside the well body 1, and a follower member 11 provided on the outer wall of the sewage pipe 5 extending outside the well body 1, which is adapted to deform as the sealing member 10 rotates relative to the pipe opening toward the outside of the sewage pipe 5. Based on this structure, when the sewage inside the well body 1 is discharged to the outside of the well body 1 through the sewage pipe, the sewage in the sewage pipe will exert pressure on the sealing member 10 from inside the sewage pipe, causing the sealing member 10 to overcome the resistance of the follower member 11 and open toward the outside of the sewage pipe, thereby allowing the sewage in the sewage pipe to flow to the outside of the sewage pipe.

[0029] Based on the above structure, more specifically, the follower 11 is a spring; and a pin 13 is provided between the sealing member 10 and the drain pipe 5, with the spring sleeved on the pin 13. For this purpose, a protruding male connector 12 is provided on the outer wall of the drain pipe 5 extending outside the well body 1; the male connector 12 has a connecting hole 14 suitable for the pin 13 to pass through. The outer circumferential edge of the sealing member 10 has a protruding female connector 15 for engaging the pin 13; the female connector 15 has an adapter groove 16 suitable for the male connector 12 to be embedded in, and the female connector 15 also has a matching hole 17 communicating with the adapter groove 16; and when the pin 13 passes through the male connector 12 and the female connector 15, a spring is provided between each of the two ends of the male connector 12 and the groove wall of the adapter groove 16.

[0030] Based on this, it should be noted that both the sealing element 10 and the opening of the drain pipe 5 can be circular, and the outer diameter of the sealing element 10 can be slightly larger than the outer diameter of the opening, making it impossible for the sealing element 10 to rotate into the drain pipe 5. Furthermore, when the sealing element 10 seals the opening of the drain pipe 5, the spring applies resistance to the female connector 15 and the male connector 12, maintaining the sealing element 10 in a state of sealing the drain pipe 5. When the drain pipe 5 is discharging sewage, the sewage inside the drain pipe 5 will generate water pressure on the sealing element 10. This water pressure overcomes the spring force, causing the sealing element 10 to open towards the outside of the drain pipe 5. When the drain pipe 5 is not discharging sewage, the spring, under its restorative action, will cause the sealing element 10 to seal the opening of the drain pipe 5 again. This structural cooperation ensures that the drain pipe 5 can only achieve unidirectional drainage.

[0031] In summary, for the rainwater and sewage diversion interception well used in this embodiment, placing the one-way valve externally at the outlet of the sewage pipe 5 makes it easy to process and assemble.
