[0025] Example:

[0026] like Figure 1 and 2 As shown, this embodiment provides a flow regulation and interception well structure, including:

[0027] A well body 1, wherein a receiving chamber 11 with an open upper end is defined in the well body 1;

[0028] A water inlet pipe 2 is provided with a water inlet 12 on the left side of the well body 1, and the water inlet pipe 2 is connected to the water inlet 12 to guide external drainage into the well body 1;

[0029] The intercepting pipe 3 is provided with an intercepting port 13 at the rear end or the front end of the well body 1, and the lower edge height of the intercepting port 13 is lower than the lower edge height of the water inlet 12, and the intercepting pipe 3 is connected with the intercepting port 13 to discharge the drainage entering the accommodating chamber 11 outward through the intercepting port 13;

[0030] The overflow pipe 4 is provided with an overflow port 14 on the right side end of the well body 1, and the lower edge height of the overflow port 14 is higher than or equal to the lower edge height of the water inlet 12. The overflow pipe 4 is connected to the overflow port 14, and a gate is provided at the overflow port 14 to open and close the overflow port 14. The overflow port 14 is opened and closed to allow the drainage entering the accommodating chamber 11 to overflow outward through the overflow port 14.

[0031] In this embodiment, a receiving chamber 11 with an open upper end is defined in the well body 1, and a water inlet 12 and an overflow port 14 are respectively provided at the left and right ends of the receiving chamber 11, and the lower edge height of the intercepting port 13 is lower than the lower edge height of the water inlet 12. An intercepting port 13 is provided on the front end wall or the rear end wall of the receiving chamber 11, and the lower edge height of the intercepting port 13 is lower than the lower edge height of the water inlet 12, so that external drainage is introduced into the well body 1 through the water inlet pipe 2. Then, since a gate is provided at the position of the overflow port 14 to open and close the overflow port 14, the overflow port 14 is used to discharge the external drainage water into the well body 1. The drain water entering the accommodating chamber 11 can be discharged outwardly through the intercepting port 13 by closing the overflow port 14, or the drain water entering the accommodating chamber 11 can be discharged outwardly through the intercepting port 13 by opening the overflow port 14, while a small part of the drain water entering the accommodating chamber 11 can overflow outwardly through the overflow port 14, thereby greatly improving the efficiency and accuracy of water treatment, thus reducing the difficulty and error of manual operation, and further improving the reliability of the overall operation. The structure is simple, which can effectively ensure that rainwater can be discharged smoothly, and can also prevent excessive sewage from entering the rainwater system.

[0032] Furthermore, it also includes a bottom plate 5 arranged on the bottom wall of the accommodating chamber 11, one end of the bottom plate 5 is connected to one end of the well body 1, and the other end is connected to a guide plate 6, the guide plate 6 is connected to the other end of the well body 1 at the end away from the bottom plate 5 and is arranged to be tilted downward to guide the drainage in the accommodating chamber 11 to the intercepting port 13.

[0033] In this embodiment, a bottom plate 5 and a guide plate 6 are respectively arranged on the bottom wall of the accommodating chamber 11. One end of the bottom plate 5 is connected to one end of the well body 1, and the other end is connected to the guide plate 6. The guide plate 6 is connected to the other end of the well body 1 at the end away from the bottom plate 5 and is inclined from top to bottom. After the external drainage is introduced into the well body 1 through the water inlet pipe 2, the drainage in the accommodating chamber 11 is guided to the intercepting port 13 through the action of the guide plate 6. In this way, the drainage in the accommodating chamber 11 can be quickly discharged outward through the intercepting port 13, thereby ensuring that all drainage or sewage enters the sewage channel through the intercepting pipe 3 for treatment.

[0034] Preferably, it also includes a driving mechanism and a controller, wherein the driving mechanism is arranged on the well body 1 and is electrically connected to the controller, and the output end of the driving mechanism is connected to the gate to drive the gate to move in the vertical direction.

[0035] Specifically, it also includes a rain gauge electrically connected to the controller, the rain gauge is suitable for measuring the rainfall situation, and the controller controls the action of the driving mechanism according to the acquired rainfall, thereby controlling the opening of the gate.

[0036] Preferably, it also includes a first liquid level sensor electrically connected to the controller, which is arranged below the overflow port 14 to detect the liquid level height in the well body 1. The controller controls the switch of the driving mechanism according to the information detected by the first liquid level sensor.

[0037] Furthermore, it also includes a manhole cover, which is opened at the upper end of the manhole body 1 and is arranged at the opening.

[0038] Specifically, it also includes a plurality of pedals 7 , which are sequentially arranged on the inner wall of the accommodating cavity 11 at intervals along the vertical direction of the well body 1 .

[0039] In particular, it also includes a second liquid level sensor and a submersible sewage pump, wherein the second liquid level sensor is arranged at a position below the interception port 13 to detect the liquid level height in the well body 1, the submersible sewage pump is arranged in the accommodating cavity 11 and the water outlet end of the submersible sewage pump is arranged corresponding to the interception port 13, and the submersible sewage pump performs switching actions according to the information detected by the second liquid level sensor.

[0040] In this embodiment, a first liquid level sensor and a second liquid level sensor are sequentially arranged in the accommodating chamber 11 from top to bottom. Specifically, the first liquid level sensor is arranged below the overflow port 14 to detect the liquid level height in the well body 1, and the second liquid level sensor is arranged below the interception port 13 to detect the liquid level height in the well body 1. When the external drainage is introduced into the well body 1 through the water inlet 12, the drainage in the accommodating chamber 11 is diverted to the interception port 13 through the function of the guide plate 6. Since the gate closes the overflow, the drainage in the accommodating chamber 11 is diverted to the interception port 13. The outlet 14 is formed by a plurality of channels, and the drainage in the accommodating chamber 11 can only be discharged to the intercepting outlet 13. If the amount of drainage water in the well body 1 is large, a large amount of drainage will be collected in the well body 1 until the current liquid level reaches the second liquid level sensor. The submersible sewage pump is controlled to work to quickly pump the drainage in the well body 1 out through the intercepting outlet 13. If the current liquid level continues to rise to the first liquid level sensor, the gate is controlled by the driving mechanism to open the overflow outlet 14, so that the drainage entering the accommodating chamber 11 can overflow out through the overflow outlet 14 at the same time.

[0041] In addition, on sunny days, the controller can ensure that all drainage enters the sewage pipe for treatment through the interception port 13; on rainy days, the controller can automatically adjust the opening of the overflow port 14 through the gate according to the amount of rainfall monitored by the rain gauge, thereby ensuring that rainwater can be discharged smoothly and preventing excessive sewage from entering the rainwater system. In this way, it can be flexibly adjusted according to real-time conditions, greatly improving the efficiency and accuracy of water treatment, while reducing the difficulty and error of manual operation, thereby improving the reliability of the overall operation.

[0042] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
