Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage separation technology, specifically a sewage interception well. Background Technology

[0002] Rainwater and sewage separation is a drainage system that separates rainwater and sewage, each using its own pipeline for discharge or subsequent treatment. Rainwater is discharged directly into rivers through a rainwater pipe network, while sewage is collected through a sewage pipe network and sent to a sewage treatment plant for treatment, preventing sewage from directly entering rivers and causing pollution. Rainwater and sewage interception wells are an essential part of the rainwater and sewage separation system. As the name suggests, buried rainwater and sewage interception wells are rainwater and sewage interception wells buried underground.

[0003] In actual use, existing intercepting wells still have some unresolved problems: when encountering situations such as short-term heavy rainfall that require a large amount of drainage, traditional well covers and well bodies are mostly fixedly connected and cannot be lifted and opened separately to increase the drainage diameter, which easily leads to rainwater accumulation. Cleaning the intercepting components often requires first disassembling the well cover and then separately removing the intercepting cylinder and intercepting pan, which is a cumbersome process and increases the workload of maintenance personnel. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a intercepting well to solve the problems mentioned in the background art. This utility model has a novel structure. By adjusting the correspondence between the adjustment disc and the well cover indicator block, two working modes can be quickly switched: when the indicator blocks correspond, the well cover and the intercepting cylinder are released from fixation and can move upward independently. The height is fixed by the inclined side block and the slot. At this time, the well cover opens to form a larger drainage channel to meet the demand for short-term large-volume drainage; when the handle is rotated 180 degrees to reverse the position of the indicator blocks, the well cover and the intercepting cylinder are firmly connected and can be lifted to the well opening, making it easy to directly clean the dirt in the intercepting disc and the intercepting cylinder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage interception well, comprising a well body, a drain pipe fixedly installed on the outer wall of the well body and communicating with its inner cavity, an installation ring block fixedly connected to the top of the well body, a well cover with multiple holes provided in the middle of the installation ring block, a sewage interception cylinder and a sewage interception plate provided inside the well body, the sewage interception cylinder being located above the sewage interception plate and fixedly connected to it, multiple drainage holes being provided on the periphery of the sewage interception cylinder and the upper side of the sewage interception plate, and a connecting component being provided between the well cover, the sewage interception cylinder, and the well body.

[0006] Furthermore, the inner wall of the well body is provided with oppositely arranged displacement grooves on both sides, the displacement grooves extend longitudinally to the top of the mounting ring block, the well cover is provided with displacement strips that slide in cooperation with the displacement grooves on both sides, and the sludge trap is provided with displacement blocks that slide in cooperation with the displacement grooves on both sides.

[0007] Furthermore, the connecting assembly includes an adjusting disc that rotatably engages with a groove in the center of the manhole cover, and a limiting groove that rotatably engages with the adjusting disc is provided on the upper side of the manhole cover. The inner walls on both sides of the limiting groove are provided with through grooves extending outwards.

[0008] Furthermore, the inner wall of the through groove is slidably fitted with an L-shaped strip, and the outer sides of the two displacement strips are provided with sliding grooves. The longitudinal edge of the L-shaped strip is laterally slidably fitted in the sliding groove, and the transverse edge of the L-shaped strip is divided into two segments with a first spring installed between them.

[0009] Furthermore, the longitudinal side of the L-shaped strip is linearly arrayed with multiple inclined edge blocks, the inclined edges of the inclined edge blocks are set upwards, and the inner wall of the displacement groove is provided with multiple slots in a linear array, the inclined edge blocks and slots cooperating with each other.

[0010] Furthermore, a fixing block is installed inside the through groove, and an abutment rod that slides through and is slidably fitted on the fixing block is installed on the side of the L-shaped strip facing the adjustment plate. A second spring is installed between the abutment rod and the fixing block.

[0011] Furthermore, the bottom of the adjusting disc is equipped with an elliptical block that cooperates with the abutment rods on both sides, and the bottom of the elliptical block is equipped with an L-shaped connecting block. The top of the intercepting cylinder is provided with a slot facing downwards, and the bottom of the slot is provided with a circular groove. The L-shaped connecting block cooperates with the slot and the circular groove.

[0012] Furthermore, corresponding indicator blocks are installed on the upper side of the adjusting disc and the upper side of the manhole cover, and a handle is fixedly connected in the groove in the middle of the adjusting disc.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model allows for quick switching between two working modes by adjusting the correspondence between the adjustment disc and the manhole cover indicator block: when the indicator blocks correspond, the manhole cover and the intercepting cylinder are released from fixation and can move upward independently, with the height fixed by the inclined side block and the slot. At this time, the manhole cover opens to form a larger drainage channel, meeting the demand for short-term large-volume drainage; when the handle is rotated 180 degrees to reverse the indicator block setting, the manhole cover and the intercepting cylinder are firmly connected and can be lifted to the opening of the manhole body, facilitating direct cleaning of the dirt in the intercepting disc and the intercepting cylinder.

[0015] 2. In this invention, after the manhole cover and the intercepting cylinder are fixedly connected via an L-shaped connecting block, a groove, and a circular groove, rotating the adjusting disc reverses the orientation of the indicator block. At this point, the inclined locking block engages with the slot to lift the entire intercepting assembly to the opening of the manhole body, eliminating the need for step-by-step disassembly of the manhole cover and the intercepting assembly. Maintenance personnel can directly clean the exposed intercepting disc and intercepting cylinder, reducing operational steps, shortening maintenance time, and lowering cleaning difficulty.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 5 This utility model provides a technical solution: a sewage interception well, including a well body 1, a drain pipe 2 fixedly installed on the outer wall of the well body 1 and communicating with its inner cavity, an installation ring block 3 fixedly connected to the top of the well body 1, a well cover 4 with multiple holes in the middle of the installation ring block 3, a sewage interception cylinder 5 and a sewage interception plate 6 arranged inside the well body 1, the sewage interception cylinder 5 being located above the sewage interception plate 6 and fixedly connected to it, multiple drainage holes 7 being opened on the periphery of the sewage interception cylinder 5 and the upper side of the sewage interception plate 6, and a connecting component 8 being provided between the well cover 4, the sewage interception cylinder 5 and the well body 1.

[0024] In this embodiment, the inner wall of the well body 1 has oppositely arranged displacement grooves 9 on both sides, which extend longitudinally to the top of the mounting ring block 3. The well cover 4 has displacement strips 11 on both sides that slide in cooperation with the displacement grooves 9. The intercepting disc 6 has displacement blocks 10 on both sides that slide in cooperation with the displacement grooves 9. The connecting assembly 8 includes an adjusting disc 801 that rotatably engages with the groove in the middle of the well cover 4. The upper side of the well cover 4 has a downwardly opening limiting groove 804 that rotatably engages with the adjusting disc 801. The inner walls of the limiting groove 804 on both sides have transversely extending through grooves 8. 05, the inner wall of the through groove 805 is slidably fitted with an L-shaped strip 806, and the outer sides of the two displacement strips 11 are provided with sliding grooves 808. The longitudinal side of the L-shaped strip 806 is slidably fitted in the sliding groove 808. The transverse side of the L-shaped strip 806 is divided into two segments and a first spring 807 is installed between them. The longitudinal side of the L-shaped strip 806 is linearly arrayed and fixedly connected with multiple inclined edge blocks 809. The inclined edge of the inclined edge blocks 809 is set upward. The inner wall of the displacement groove 9 is provided with multiple slots 12 in a linear array. The inclined edge blocks 809 cooperate with the slots 12.

[0025] Specifically, when the height of the manhole cover 4 is raised separately and a large amount of water is drained, the adjusting plate 801 corresponds to the indicator block 803 of the manhole cover 4, and the manhole cover 4 and the intercepting cylinder 5 are in a released state. At this time, the manhole cover 4 can be pulled upward by the handle 802. During the upward movement of the manhole cover 4, the longitudinal edges of the L-shaped strips 806 on both sides slide in the displacement groove 9. The inclined edge locking block 809 on the longitudinal edge of the L-shaped strip 806 cooperates with the locking groove 12. The L-shaped strip 806 is divided into two sections by the transverse edge and the first spring 807 is installed between them. This does not affect the upward movement of the manhole cover 4. At the same time, when the manhole cover 4 is released, the inclined edge locking block 809 and the locking groove 12 engage to fix the height of the manhole cover 4.

[0026] In this embodiment, a fixing block 810 is installed inside the through groove 805. An abutment rod 811 is installed on the side of the L-shaped strip 806 facing the adjusting plate 801, which is slidably fitted onto the fixing block 810. A second spring 812 is installed between the abutment rod 811 and the fixing block 810. An elliptical block 813 is installed at the bottom of the adjusting plate 801, which cooperates with the abutment rods 811 on both sides. An L-shaped connecting block 814 is installed at the bottom of the elliptical block 813. A slot 815 is opened downward at the top of the intercepting cylinder 5. A circular groove 816 is opened at the bottom of the slot 815. The L-shaped connecting block 814 cooperates with the slot 815 and the circular groove 816. Corresponding indicator blocks 803 are installed on the upper side of the adjusting plate 801 and the upper side of the manhole cover 4. A handle 802 is fixedly connected in the groove in the middle of the adjusting plate 801.

[0027] Specifically, the lateral edges of the two L-shaped strips 806 are connected by the abutment rod 811, the second spring 810, and the fixing block 810, causing the two L-shaped strips 806 to move closer to the center of the adjusting disc 801. Since the bottom of the fixing block 810 has an elliptical block 813 that cooperates with the end of the abutment rod 811, when the adjusting disc 801 corresponds to the indicator block 803 of the manhole cover 4, the bulging sides of the elliptical block 813 overlap with the two abutment rods 811. At this time, the second spring 812 is in a compressed state, pushing the L-shaped strips 806 outward, which can be engaged with the slot 12 by the inclined side locking block 809. The height of the manhole cover 4 is fixed; the L-shaped connecting block 814 is placed in the circular groove 816 through the slot 815, and the handle 802 is rotated 180 degrees. The adjusting plate 801 is set opposite to the indicator block 803 of the manhole cover 4. At this time, the manhole cover 4 is connected to the intercepting cylinder 5. The two bulging sides of the elliptical block 813 overlap with the two abutting rods 811. The height of the manhole cover 4 and the intercepting cylinder 5 can be fixed by the engagement of the inclined side locking block 809 with the locking groove 12. The intercepting plate 6 at the bottom of the intercepting cylinder 5 can be lifted to the opening of the well body 1 to facilitate the cleaning of the dirt inside.
