Description

Technical Field

[0001] The invention relates to the technical field of interception wells, and in particular to a tunnel interception well and a working method thereof. Background Art

[0002] An interception well is a well structure used to intercept sewage. It is generally used in a combined rainwater and sewage system to separate rainwater from sewage. In the dry season, there is less water flowing into the water inlet, and there is only sewage in the pipe. The interception well can intercept the sewage and guide it to the sewage pipe to achieve sewage diversion; in the rainy season, rainwater mixed with sewage pours in from the water inlet in large quantities. Some rainwater and sewage will still be intercepted and flow into the sewage pipe, and the rest of the rainwater overflows through the weir in the well and continues to flow downstream, thus not delaying drainage in the rainy season.

[0003] Interception wells are of great significance for the collection and drainage of urban sewage, especially in some old communities or narrow alleys where it is impossible to lay sewage pipes. Interception wells play a major role in collecting alley sewage and draining rainwater. However, such old communities and narrow alleys also have certain requirements for the volume of interception wells. How to meet the requirements of sewage interception in the dry season and timely discharge of rainwater in the rainy season under the premise of shrinking the volume of the interception well is an urgent problem to be solved. Moreover, the opening and closing of different pipes in the interception well are controlled by gates, and the gate driving mechanism consumes a lot of energy.

[0042] Interception wells are of great significance for the collection and drainage of urban sewage, especially in some old communities or narrow alleys where it is impossible to lay sewage pipes. Interception wells play a major role in collecting alley sewage and draining rainwater. However, such old communities and narrow alleys also have certain requirements for the volume of interception wells. How to meet the requirements of sewage interception in the dry season and timely discharge of rainwater in the rainy season under the premise of shrinking the volume of the interception well is an urgent problem to be solved.

[0043] In this regard, the present application proposes a tunnel interception well. When the daily water flow is small, the sewage can be intercepted in the first well chamber 110 and flow out from the sewage interception branch pipe 112 to the external sewage pipe; when the water flow is large on rainy days, the rainwater passes over the first water hole 140 and drives the driving member 410 to move, and the impact force of the water flow is used to close the first gate 200 and open the second gate 300, thereby reducing dependence on external energy and playing a role in energy conservation and emission reduction. In addition, the present application also proposes a working method for the above-mentioned tunnel interception well, which can guide domestic sewage when it is not raining, and can close the first gate 200 when it is raining to prevent a large amount of water from flowing into the sewage interception branch pipe 112, and open the second gate 300 to discharge the water as soon as possible to prevent flooding of the tunnel.

[0044] Reference Figure 1 The tunnel intercepting well in the embodiment of the first aspect of the present application comprises an intercepting well body 100, a first gate 200, a second gate 300 and a linkage assembly. The intercepting well body 100 is the main structure of the tunnel intercepting well, the first gate 200 is used to control whether the water flows to the sewage pipe, and the second gate 300 is used to control whether the water flows to the drainage pipe. The linkage assembly connects the first gate 200 and the second gate 300, and when the first gate 200 is opened, the second gate 300 is driven to close, and when the first gate 200 is closed, the second gate 300 is driven to open.

[0045] Specifically, the intercepting well body 100 includes a first well chamber 110, a second well chamber 120 and a third well chamber 130 which are interconnected. A wall is provided between the first well chamber 110 and the second well chamber 120 and a first water hole 140 is provided on the wall. A wall is provided between the second well chamber 120 and the third well chamber 130 and a second water hole 150 is provided on the wall. The first well chamber 110 is provided with a water inlet pipe 111 and a sewage interception branch pipe 112, and water flows into the intercepting well body 100 from the water inlet pipe 111. It is worth noting that the bottom of the first water hole 140 is higher than the top of the sewage interception branch pipe 112, so that when the water volume is insufficient and the water level is lower than the first water hole 140, the water flows out from the sewage interception branch pipe 112, which plays a role in guiding sewage; when the water volume is sufficient and the water level exceeds the bottom of the first water hole 140, the excess water will overflow to the first water hole 140 and enter the second well chamber 120.

[0046] The first gate 200 is movably connected to the sewage interception branch pipe 112 to control whether the sewage interception branch pipe 112 is connected to the first well chamber 110. The second gate is movably connected to the second water hole 150 to control whether the third well chamber 130 is connected to the second well chamber 120.

[0047] The linkage assembly is connected to the first gate 200 and the second gate 300 to realize the linkage of the two gates. The linkage assembly includes a driving member 410 suspended in the first water hole 140. The water flow can drive the driving member 410 to move, thereby driving the first gate 200 and the second gate 300 to open or close.

[0048] When no water flows through the first water hole 140, the driving member 410 is suspended in midair, at which time the first gate 200 is opened and the second gate 300 is closed, and sewage flows into the sewage interception branch pipe 112 to complete the sewage discharge work. When water flows through the first water hole 140, the driving member 410 moves downward under the action of the water flow, at which time the first gate 200 is closed and the second gate 300 is opened, and the water flows through the first water hole 140 and the second water hole 150 in sequence, and is finally discharged to the outside to complete the drainage work.

[0049] Optionally, for the driving method of the driving member 410, a slope is provided on the side of the driving member 410 facing the water flow. When the water flow hits, the slope converts part of the horizontal component of the water flow into a vertical component to drive the driving member 410 to descend, thereby completing the triggering of the linkage assembly.

[0050] Furthermore, in order to make the triggering of the driving member 410 more stable and prevent the situation where the impact force of the water flow is insufficient to move the driving member 410 downward, the linkage assembly further includes a magnet 420, which is installed at the bottom of the first water hole 140. The driving member 410 is magnetic and can attract the magnet 420. Therefore, when the driving member 410 is driven by the water flow to descend, the magnetic force of the magnet 420 on the driving member 410 gradually increases, so that the driving member 410 moves downward smoothly to trigger the linkage assembly to act.

[0051] As for the specific structure of the linkage assembly, it includes a screw mechanism 430 and a transmission mechanism 440. There are three screw mechanisms 430 and they are respectively connected to the first gate 200, the second gate 300 and the driving member 410. The screw mechanism 430 is used to convert the vertical force of the gate and the driving member 410 into a rotational force, which is then transmitted by the transmission mechanism 440. The screw mechanism 430 includes a telescopic sleeve and a screw rod. One end of the screw rod is connected to the first gate 200, the second gate 300 or the driving member 410, and the other end of the screw rod is inserted into the telescopic sleeve and threadedly connected thereto. When the screw rod is driven by the gate or the driving member 410 to move up and down, it can drive the telescopic sleeve to rotate. The transmission mechanism 440 is connected to each telescopic sleeve to transmit power, so as to realize the linkage of the first gate 200, the second gate 300 and the driving member 410.

[0052] Regarding the specific transmission mode of the transmission mechanism 440, in some embodiments, the transmission mechanism 440 includes a sprocket and a chain, each telescopic sleeve is equipped with a sprocket, and the chain is wound around each sprocket to form a chain drive. In other embodiments, the transmission mechanism 440 includes a pulley and a synchronous belt, each telescopic sleeve is equipped with a pulley, and the synchronous belt is wound around each pulley to form a belt drive.

[0053] In this embodiment, the transmission mechanism 440 includes a bevel gear set 441 and a transmission rod 442. The bevel gear set 441 includes two bevel gears meshing with each other. One of the bevel gears in the bevel gear set 441 is connected to the telescopic sleeve, and the other bevel gear in the bevel gear set 441 is connected to the transmission rod 442, and power is transmitted through the transmission rod 442. Therefore, each bevel gear set 441 is linked through the transmission rod 442.

[0054] Furthermore, the transmission mechanism 440 also includes a universal joint, which is installed between the bevel gear set 441 and the telescopic sleeve, or between the bevel gear set 441 and the transmission rod 442, or between two connected transmission rods 442. The universal joint is used to change the transmission direction of the rotational force.

[0055] It is easy to understand that there may be multiple bevel gear sets 441 , transmission rods 442 , and universal joints in the transmission mechanism 440 , and the specific number is selected according to the actual working environment.

[0056] Further, refer to Figure 2 and Figure 3 A filter screen 1121 is also installed at the pipe opening of the sewage interception branch pipe 112 to prevent solid impurities from entering and causing pipe blockage. The solid impurities are intercepted by the filter screen 1121 and retained in the first well chamber 110 .

[0057] Furthermore, a buffer layer 121 is disposed in the second well chamber 120 , and a slope is disposed on the top of the buffer layer 121 to guide water flow toward the third well chamber 130 .

[0058] Furthermore, the third well chamber 130 is provided with a water outlet pipe 131 and a pebble cushion layer 132 . The pebble cushion layer 132 is arranged between the water outlet pipe 131 and the second water hole 150 to intercept solid impurities in rainwater.

[0059] A working method for the above-mentioned tunnel interception well in the second aspect of the present application includes a sewage diversion working mode and a rainwater discharge working mode, wherein:

[0060] The sewage diversion working mode includes the following steps:

[0061] S110. Sewage enters from the water inlet pipe 111, and the water does not overflow from the first water hole 140 and stays in the first well chamber 110;

[0062] S120. The second gate 300 is closed, the driving member 410 is suspended in midair, and the first gate 200 is pulled open by the linkage assembly;

[0063] S130. The sewage flows out from the sewage interception branch pipe 112 to the external sewage pipe;

[0064] The rainwater discharge working mode includes the following steps:

[0065] S210. A water flow mixed with rainwater and sewage enters from the water inlet pipe 111, and the water flows from the first water hole 140 to the second well chamber 120;

[0066] S220. The water flow impact causes the driving member 410 to move downward, driving the first gate 200 to close through the linkage assembly, and driving the second gate 300 to open;

[0067] S230. The water flows out from the second water hole 150, completing the discharge of rainwater.

[0068] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
