[0030] Please refer to Figure 1 and 2 , the present application is suitable for intercepting sewage of intercepting well, relates to the present situation culvert 100, comprising:

[0031] The present situation culvert 100 is divided into water inlet cavity 101 and water outlet cavity 102 by partition, the water inlet cavity 101 is communicated with the water outlet cavity 102 through flap door 103, the lower part of the water inlet cavity 101 is provided with float valve 104, and the well head 105 is arranged on the water inlet cavity 101 and the water outlet cavity 102.

[0032] The residue blocking assembly 200 is arranged at the water inlet of the water inlet cavity 101, and is used for filtering the residue in the sewage entering the water inlet cavity 101.

[0033] The traditional intercepting well lacks the residue blocking assembly, cannot block the sundries in the sewage, and the sewage can cause the problem of pipe blockage after a long time. In the present application, the residue blocking assembly 200 is arranged to block the sundries in the passing sewage, so that the problem of pipe blockage is avoided. The residue blocking assembly can be directly cleaned outside the intercepting well in the cleaning process, without the need for manual entry into the intercepting well, so that the cleaning difficulty is reduced, the cleaning efficiency is improved, and the reinstallation process after cleaning is simple and fast, and the reutilization rate is high.

[0034] In an embodiment, please refer to Figure 2 The residue blocking assembly 200 includes a mounting bracket 201 fixedly arranged in the water inlet cavity 101, the mounting bracket 201 is fixed through a support rod 203 connected to the inner wall of the water inlet cavity 101 at one end, the mounting bracket 201 is provided with a vertical sliding rail 202, the vertical sliding rail 202 is provided with an inner support frame 204 in sliding fit, the inner support frame 204 is matched with the shape of the mounting bracket 201, and the inner support frame 204 is provided with a residue blocking net 205, the residue blocking net 205 covers the other three continuous vertical surfaces of the inner support frame 204 except the vertical surface opposite to the water inlet of the water inlet cavity 101.

[0035] It should be noted that the top surface and the surface facing the direction of sewage flow of the mounting bracket 201 are open, while the other surfaces are panel structures with water passage holes. The inner support 204 is fixed to the mounting bracket 201 by screws on the top. The sliding engagement between the inner support 204 and the vertical slide rail 202 allows the inner support 204 to be unscrewed and pulled upwards directly during subsequent cleaning. This makes disassembly convenient and quick, eliminating the need for manual entry into the interception well and improving work efficiency.

[0036] When sewage passes through the intercepting well, it passes through the sludge net 205 before entering the inlet chamber 101. The impurities contained therein are filtered out and remain on one side of the sludge net 205. The sludge net 205 is directly facing the direction of sewage flow. The water flow will press the sludge net 205 tightly onto the mounting bracket 201, and there will be no problem of detachment.

[0037] In one embodiment, please refer to Figure 3 and Figure 4 The vertical rod of the inner support frame 204 has a groove 2041, and the slag net 205 is folded and placed in the groove 2041 and is taut as a whole;

[0038] The inner support frame 204 is provided with inclined blocks 209 on both sides near the water inlet end of the water inlet chamber 101. The inclined blocks 209 have a structure that is wider at the bottom and narrower at the top, and the surface of the inclined blocks 209 has a groove for installing the slag net 205.

[0039] The corner contacts of the slag-blocking net 205 and the inner support frame 204 are all embedded connections, which are detachable. This makes it easy to remove the entire slag-blocking net 205 during subsequent cleaning, clean it, and then reinstall it, improving utilization. Moreover, it allows only the slag-blocking net 205 to be removed during cleaning, reducing operational difficulty and improving work efficiency. Since the slag-blocking net 205 needs to be pulled up from the bottom end first, and then pulled out together with the top end, the inclined block 209 is designed to ensure that the slag-blocking operation of the sewage is not affected during the smooth removal of the slag-blocking net 205, preventing sewage from leaking out of the uncovered areas of the slag-blocking net 205, and ensuring that all passing sewage can be intercepted.

[0040] In one embodiment, please refer to Figure 2 The mounting bracket 201 has a sloping end away from the water inlet of the water inlet cavity 101, and the bottom of the mounting bracket 201 has an extension plate that connects to the lower part of the water inlet end of the water inlet cavity 101.

[0041] The inclined structure allows wastewater to directly enter the inlet chamber 101 along its original path, without having to follow a folding path.

[0042] The line moves and falls into the inlet chamber 101, ensuring the flow rate of sewage. The extended planar structure can collect debris in the blocked sewage, making it easier to clean the debris when the slag net 205 is lifted later.

[0043] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The two ends of the slag-blocking net 205 located on the lower part of the surface of the inclined block 209 are connected to the first pull rope 207, and the two ends located on the upper part of the surface of the inclined block 209 are connected to the first pull rope 207.

[0044] A second pull rope 206 is connected, and two ends located in the upper part of the inner support frame 204 are connected to a third pull rope 208. The movable ends of the first pull rope 207, the second pull rope 206 and the third pull rope 208 are all bolted to the hook ring 210 on the inner wall of the wellhead 105.

[0045] Specifically, during the cleaning process, the first rope 207 is pulled, causing the slag-blocking net 205 to gradually converge upwards. During this pulling process, because the slag-blocking net 205 moves vertically upwards, it helps to prevent the slag from being blocked.

[0046] The connection between the slag net 205 and the inner support frame 204 is disengaged sequentially. The trapped debris remains within the retracted space. After pulling the bottom end of the slag net 205 to be level with its top end, the second pull rope 206 and the third pull rope 208 are pulled upwards together until the entire slag net 205 is pulled out.

[0047] After collecting the debris and cleaning the slag-blocking net 205, remove the inner support frame 204 and reinstall the slag-blocking net 205 to complete the overall cleaning operation. The operation is simple, quick, and efficient.

[0048] In one embodiment, please refer to Figure 5 The inclined end of the mounting bracket 201 is provided with an outwardly rotatable baffle 211. Water passage holes are provided on the baffle 211. A slag-blocking net 205 covers the surface of the baffle 211 and has redundancy.

[0049] With the remaining capacity, when the baffle 211 rotates outward to open, the redundant slag-catching net 205 gradually tightens outward. Because the portion of the slag-catching net 205 located on the inclined surface filters out impurities that will slide downward and accumulate at the bottom, this design...

[0050] When too much debris accumulates on the bottom slag-blocking net 205, the baffle 211 can rotate outward to release the redundant slag-blocking net 205, thereby increasing the slag-blocking net 205's capacity to collect debris, which helps to extend the slag-blocking time and avoid repeated cleaning operations in a short period of time.

[0051] In one embodiment, please refer toFigure 5 The baffle 211 is rotatably arranged outwardly around the top end thereof by a rotating mechanism, the rotating mechanism is remotely controlled, and a sensor (not numbered in the figure) is arranged on the lower part of the surface of the baffle 211 for detecting the flow rate of the passing water flow. When the flow rate passing through the baffle 211 is lower than a set value, the baffle 211 is controlled to open outwardly to release the redundant debris blocking net 205. The sensor is a flow rate sensor, and the output end thereof is electrically connected with a controller, and the controller is electrically connected with a remote control module. When the flow rate passing through the baffle 211 is lower than the set value, the staff remotely controls to open the baffle 211 to release the redundant debris blocking net 205, expand the capacity of the debris blocking net 205 for collecting sundries, prolong the time for blocking debris, and avoid repeated cleaning operation in a short time.

[0052] In an embodiment, the rotating angle of the baffle 211 is 0-45°, and a position sensor is arranged on the mounting bracket 201 for detecting whether the baffle 211 is rotated to the vertical state. In this way, when the baffle 211 is rotated to the vertical state, it indicates that the slope state of the debris blocking net 205 does not exist, at this time, the amount of the redundant debris blocking net 205 is close to complete release, and the staff needs to perform cleaning operation, which helps the staff to judge the time when the debris blocking net 205 needs to be cleaned.

[0053] In an embodiment, please refer to Figure 1 The flap door 103 is arranged to be rotatable in a tilt manner, and the rotating direction is towards the water outlet cavity 102. For the river channel in the tidal area of the coastal area, the water level of the river channel is very high during the high tide period. In order to avoid the river water from flowing into the sewage pipe and the culvert, the anti-inversion facility is very important, and the traditional intercepting well does not have the anti-inversion facility. Through the arrangement of the flap door 103, the water flow in the existing culvert 100 is realized to be unidirectional, and the problem that the river water is inverted into the intercepting well is avoided.

[0054] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
