Description

Technical Field

[0001] This utility model relates to the field of building drainage, and in particular to a building drainage pipe well. Background Technology

[0002] An existing patent (publication number: CN110424462A) discloses a prefabricated building drainage pipe well: It includes a base, with a first side plate and a second side plate fixedly installed on both sides of the top of the base. Multiple prefabricated blocks are symmetrically arranged and fixedly installed on one side of the first side plate. A curved groove is formed on the side of each prefabricated block away from the first side plate, and a vertical pipe is movably fitted into the curved groove. Two of each of the first and second side plates are provided. The two first side plates, two second side plates, and the base combine to form a pipe well structure with an opening at the top. The first side plates, second side plates, and base are all made of concrete. Multiple placement holes are formed on both the first and second side plates, and horizontal pipes are installed in these holes. Multiple ladders are fixedly installed sequentially from top to bottom on one side of the second side plate. Two symmetrically arranged first clamps are fixedly installed on both sides of the precast block. An installation block is fixedly installed on one side of the first clamp, and a spring is fixedly installed on one side of the installation block. However, the pipe well, which is the transition position between two horizontal pipes, does not have a filter structure, which can easily lead to the blockage of large blocky impurities when the sewage flows through the pipe. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a building drainage pipe well in which, when the filter bucket is located at the bottom of the well body, the side filter screen precisely corresponds to the interface of the drainage pipe below, directly intercepting large impurities in the water flow, such as gravel, dead branches, and garbage, thus preventing them from entering the pipe and causing physical blockage.

[0004] The objective of this utility model is achieved through the following technical solution: A building drainage pipe well includes a drainage pipe well body, a rectangular lower plate, an L-shaped mounting plate, a side fixing plate, a handle, a hoisting rotating rod, a positioning shaft, a filter bucket, a lower filter screen, a side filter screen, and a drainage pipe. The lower side of the drainage pipe well body has a first pipe interface and a second pipe interface. The drainage pipe is adapted to the first pipe interface and inserted into it. The drainage pipe is also adapted to the second pipe interface and inserted into it. The filter bucket is adapted to the drainage pipe well body and inserted into it. The filter bucket slides within the drainage pipe well body. The side of the filter bucket has a filter bucket side groove. Inside the drainage pipe well body is a set of strip-shaped limiting rods. The strip-shaped limiting rods are adapted to the side grooves of the filter bucket and inserted into them, sliding within the side grooves.

[0005] The bottom of the filter bucket is connected to a lower filter screen, and the side of the filter bucket is connected to a side filter screen. The side filter screen corresponds to the No. 1 pipe interface. The side of the filter bucket has a clearance groove, which is located below the No. 2 pipe interface. The upper part of the filter bucket is connected to an upper connecting plate, and the upper part of the upper connecting plate is connected to a lifting ring. The upper side of the drainage pipe well body has a well body side plate. Beneficial effects

[0006] 1. This utility model comprises a set of drainage pipes that are respectively connected to pipe interface 1 and pipe interface 2, so that the set of drainage pipes are distributed at two different positions on both sides of the drainage pipe well body. Water in the higher drainage pipe flows through the drainage pipe well body into the lower drainage pipe. A filter bucket is placed at the bottom of the drainage pipe well body to settle the silt in the water flowing through the drainage pipe well body. A lower filter screen is installed at the bottom of the filter bucket. When the filter bucket slides upward, it filters the water inside the drainage pipe well body, causing the water to sink and the silt to settle onto the lower filter screen. A side filter screen is installed and fixed on the side of the filter bucket. When the filter bucket is placed at the bottom of the drainage pipe well body, the side filter screen is opposite to the lower drainage pipe, so that water flows from the upper drainage pipe through the drainage pipe well body and into the lower drainage pipe. Inside the well, the side filter screen filters the water flowing into the drainage pipe, preventing large impurities from entering the drainage pipe below and causing blockages. A set of strip-shaped limiting rods inserts into the side groove of the filter bucket, axially positioning the side filter screen to prevent misalignment with the lower drainage pipe, ensuring normal water flow and maintaining alignment between the side filter screen and the lower drainage pipe interface. This prevents misalignment caused by water flow impact or filter bucket movement, ensuring continuous and effective filtration. Positioning rods are installed and fixed on the side plate of the well body, inserting into the rectangular lower plate. A set of positioning rods positions the rectangular lower plate, which in turn positions the L-shaped mounting plate, suspending it above the drainage pipe well body. This prevents the lifting structure from shifting, which could cause the filter bucket to jam, ensuring smooth operation of all components. A set of side fixing plates are distributed on the L-shaped mounting plate. The positioning shaft passes through the side fixing plates and connects to the hoisting rotating rod. The handle side rod passes through the side fixing plates and connects to the hoisting rotating rod. The hoisting rotating rod can rotate between the set of side fixing plates by the cooperation of the positioning shaft and the handle side rod. The hoisting rotating rod can be rotated by holding the handle.

[0007] 2. This utility model uses a lifting ring connected to a lifting boom via a lifting rope. Rotating the boom causes the rope to wind up, pulling the filter bucket upwards and out of the drainage pipe well. This allows for the cleaning of sediment and impurities within the filter bucket. Maintenance personnel do not need to enter the well; they only need to hold the handle at the wellhead and rotate the lifting boom to pull the filter bucket out of the well via the winding rope, directly cleaning the sediment and intercepted impurities inside. The device achieves graded protection through a dual filtration structure of a lower filter screen and a side filter screen. When the filter bucket is at the bottom of the well, the side filter screen precisely aligns with the lower drainage pipe interface, directly intercepting large impurities in the water flow, such as gravel, twigs, and garbage, preventing them from entering the pipe and causing physical blockage. When the filter bucket slides upwards, the lower filter screen comprehensively filters the water accumulated in the well, accelerating the sedimentation of fine particles such as sediment, preventing long-term accumulation and sludge blockage in the pipe, adapting to filtration needs under different water levels and flow conditions.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A building drainage pipe well includes a drainage pipe well body 01, a rectangular lower plate 05, an L-shaped mounting plate 08, a side fixing plate 09, a handle 10, a hoisting rotating rod 12, a positioning shaft 13, a filter bucket 14, a lower filter screen 16, a side filter screen 17, and drainage pipes 21. The lower side of the drainage pipe well body 01 has a first pipe interface 02 and a second pipe interface 03. The drainage pipe 21 is adapted to the first pipe interface 02 and inserted into it. The drainage pipe 21 is adapted to the second pipe interface 03 and inserted into it. A set of drainage pipes 21 are respectively connected to the first pipe interface 02 and the second pipe interface 03, so that the set of drainage pipes 21 are distributed at two unequal positions on both sides of the drainage pipe well body 01. Water in the higher drainage pipe 21 flows through the drainage pipe well body 01 into the lower one. Inside the drainage pipe 21, the filter bucket 14 is adapted to the drainage pipe well body 01. The filter bucket 14 is inserted into the drainage pipe well body 01 and placed at the bottom of the drainage pipe well body 01 to settle the silt in the water flowing through the drainage pipe well body 01. The filter bucket 14 slides inside the drainage pipe well body 01. The side of the filter bucket 14 has a filter bucket side groove 15. Inside the drainage pipe well body 01, there is a set of strip-shaped limiting rods 04. The strip-shaped limiting rods 04 are adapted to the filter bucket side groove 15 and are inserted into the filter bucket side groove 15. The strip-shaped limiting rods 04 slide inside the filter bucket side groove 15. The set of strip-shaped limiting rods 04 axially positions the strip-shaped limiting rods 04 to prevent the side filter screen 17 from being misaligned with the lower drainage pipe 21, ensuring normal water flow and ensuring that the side filter screen 17 is always aligned with the lower drainage pipe interface. This avoids filtration misalignment caused by water flow impact and filter bucket shaking, ensuring the continuous effectiveness of the filtration function.

[0014] Example 2: The bottom of the filter bucket 14 of this utility model is connected to a lower filter screen 16. The lower filter screen 16 is installed at the bottom of the filter bucket 14. When the filter bucket 14 slides upwards, it filters the water inside the drainage pipe well 01, causing the water to sink and filtering the sediment onto the lower filter screen 16. A side filter screen 17 is connected to the side of the filter bucket 14. The side filter screen 17 corresponds to the first pipe interface 02. The side filter screen 17 is installed and fixed on the side of the filter bucket 14. When the filter bucket 14 is placed at the bottom of the drainage pipe well 01, the side filter screen 17 is aligned with the drainage pipe 21 below it. Water flows from the upper drainage pipe 21 through the drainage pipe well body 01 and into the lower drainage pipe 21. The side filter screen 17 filters the water flowing into the drainage pipe 21 to prevent large impurities in the water from entering the lower drainage pipe 21 and to prevent blockage inside the drainage pipe 21. The filter bucket 14 has a relief groove 20 on its side, which is located below the second pipe interface 03. The upper part of the filter bucket 14 is connected to the upper connecting plate 18, and the upper part of the upper connecting plate 18 is connected to the hanging ring 19. The upper side of the drainage pipe well body 01 has a well body side plate 06.

[0015] Example 3: The upper part of the well body side plate 06 of this utility model is connected to a positioning rod 07, which is fixed on the well body side plate 06. The lower part of the L-shaped mounting plate 08 is connected to a rectangular lower plate 05. The positioning rod 07 passes through the rectangular lower plate 05. A set of positioning rods 07 are distributed on the well body side plate 06. The set of positioning rods 07 positions the rectangular lower plate 05, and then positions the L-shaped mounting plate 08, so that the L-shaped mounting plate 08 is suspended above the drainage pipe well body 01. This avoids the filter bucket 04 from being stuck due to the displacement of the hoisting structure, and ensures smooth linkage of all components of the device. The upper part of the side fixing plate 09 is connected to the L-shaped mounting plate 08. A set of side fixing plates 09 are distributed on the L-shaped mounting plate 08. The side of the hoisting rotating rod 12 is in contact with the side fixing plate 09. The side fixing plates 09 are symmetrically arranged at both ends of the hoisting rotating rod 12.

[0016] Example 4: The handle 10 of this utility model has a handle side rod 11 on its side. The handle side rod 11 passes through the side fixing plate 09 and is connected to the hoisting rotating rod 12. The positioning shaft 13 passes through the side fixing plate 09 and is connected to the hoisting rotating rod 12. The positioning shaft 13 cooperates with the handle side rod 11 to make the hoisting rotating rod 12 rotate between a set of side fixing plates 09. The hoisting rotating rod 12 can rotate by holding the handle 10 and rotating it. The lower part of the hoisting rope is tied to the hoisting ring 19 and the upper part of the hoisting rope is connected to the hoisting rotating rod 12. The hoisting ring 19 is connected to the hoisting rotating rod 12 through the hoisting rope. The rotation of the hoisting rotating rod 12 causes the hoisting rope to be wound up and pull the filter bucket 14 upward. The filter bucket 14 is pulled out of the drainage pipe well body 01 to clean the mud and sand impurities inside the filter bucket 14. The maintenance personnel do not need to enter the well body. They only need to hold the handle at the well opening and rotate the hoisting rotating rod to pull the filter bucket out of the well body by winding the hoisting rope and directly clean the sediment and sand and intercepted impurities inside. The device achieves graded protection through a dual filtration structure consisting of a lower filter screen 16 and a side filter screen 17. When the filter bucket 04 is at the bottom of the well, the side filter screen 17 precisely aligns with the interface of the drainage pipe below, directly intercepting large impurities in the water flow, such as gravel, dead branches, and garbage, preventing them from entering the pipe and causing physical blockage. When the filter bucket 04 slides upward, the lower filter screen 16 comprehensively filters the water accumulated in the well, accelerating the sedimentation of fine particles such as silt and preventing them from accumulating in the pipe over a long period of time and forming sludge blockage, thus adapting to the filtration needs under different water levels and flow conditions.

[0017] Example 5: The installation steps of this utility model are as follows: First, connect the lower filter screen 16 to the lower part of the filter bucket 14, connect the side filter screen 17 to the side of the filter bucket 14, connect the lower part of the upper connecting plate 18 to the filter bucket 14, connect the lifting ring 19 to the upper connecting plate 18, install the drainage pipe 21 on the second pipe interface 03, install another drainage pipe 21 on the first pipe interface 02, insert the filter bucket 14 into the drainage pipe well body 01, insert the strip-shaped limiting rod 04 into the side groove 15 of the filter bucket, connect the positioning rod 07 to the side plate 06 of the well body, insert the positioning rod 07 into the rectangular lower plate 05, pass the positioning shaft 13 through the side fixing plate 09 and connect it to the lifting rotating rod 12, pass the handle side rod 11 through the side fixing plate 09 and connect it to the lifting rotating rod 12, tie the lower part of the lifting rope to the lifting ring 19, and tie the upper part of the lifting rope to the lifting rotating rod 12.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
