Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline energy dissipation, and in particular relates to a drainage pipe outlet discharge energy dissipation structure. Background Art

[0002] In order to meet drainage requirements, modern buildings usually need to install a drainage riser connected to the roof of the building. In order to reduce the kinetic energy of the water in the drainage riser and reduce the scouring effect of the water on the ground and surrounding objects, the water in the drainage pipe needs to be energy-dissipated.

[0003] A Chinese patent with publication number CN216075424U discloses an energy dissipation device for a drainage pipe. The scheme includes an energy dissipation pipe fitting, which is sleeved outside the drainage pipe. A plug is integrally provided at one end of the drainage pipe in the energy dissipation pipe fitting. The above scheme uses the plug to be provided at one end of the drainage pipe to evenly disperse the water entering the energy dissipation pipe fitting from the drainage pipe into the cavity, so that the water bodies collide with each other in the cavity, thereby eliminating the potential energy of part of the water body, thereby playing the role of energy dissipation.

[0004] When the above solution is in use, if there is mud and sand in the water, the mud and sand in the water in the drainage pipe will impact the plug for a long time, and the plug is easily damaged. However, the plug is integrally formed at one end of the drainage pipe, which makes it difficult to replace and maintain. Utility Model Content

[0005] The utility model aims to provide a drainage pipe outlet discharge energy dissipation structure to solve the problem of difficult maintenance in the above-mentioned solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A drainage pipe outlet discharge energy dissipation structure comprises a drainage pipe, a drainage cover and an energy dissipation pipe, wherein the drainage cover is connected from top to bottom and has a truncated cone-shaped bottom, the top of the drainage cover is fixedly sleeved on the bottom of the drainage pipe, the energy dissipation pipe is connected from top to bottom, the top of the energy dissipation pipe is detachably arranged on the bottom of the drainage cover, a support plate is fixedly arranged in the transverse direction inside the energy dissipation pipe, a buffer plate is detachably arranged on the support plate below the drainage pipe, and a plurality of through grooves are arranged at intervals along the circumference of the buffer plate on the top of the support plate.

[0008] The principle and effect of this technical solution:

[0009] The water is discharged downward through the drainage pipe and flows into the drainage cover. Part of the water flows along the side walls of the drainage cover and the side walls of the energy dissipation pipe, and the remaining water directly impacts the buffer plate after flowing out of the drainage pipe. The buffer plate eliminates part of the potential energy of this part of the water and changes the flow direction of this part of the water, so that this part of the water collides with the water flowing along the side walls of the drainage cover and the side walls of the energy dissipation pipe, further eliminating the potential energy of the water in the energy dissipation pipe. The water after energy dissipation falls out of the energy dissipation pipe through the through groove. After the buffer plate is damaged due to long-term impact of water and sediment falling from the drainage pipe, the energy dissipation pipe is first removed and then the buffer plate in the energy dissipation pipe is replaced.

[0010] Through the above-mentioned configuration, by arranging a buffer plate in the energy dissipation pipe, it is possible to change the flow direction of the water body while offsetting a portion of the potential energy of the water body, so that the water bodies in the energy dissipation pipe collide with each other, further eliminating the potential energy of the water body, thereby achieving the purpose of energy dissipation. In addition, by arranging the energy dissipation pipe detachably at the bottom of the drainage cover, the buffer plate can be easily replaced, thereby reducing the difficulty and cost of maintenance.

[0011] In the utility model, a connecting rod is fixedly arranged at the bottom of the buffer plate along its axial direction, the connecting rod is slidably inserted into the support plate, and a compression spring is sleeved between the buffer plate and the support plate outside the connecting rod.

[0012] The principle and effect of this technical solution:

[0013] When water falls from the drain pipe and impacts the buffer plate, it pushes the buffer to move downward and compresses the compression spring, making it elastic.

[0014] Through the above arrangement, the buffer plate, under the action of the compression spring, can buffer the falling water, preventing the water from directly pushing the buffer plate to hit the support plate, thereby avoiding damage to the support plate and reducing vibration.

[0015] In the utility model, a truncated cone-shaped drainage block is fixedly arranged on the top of the buffer plate along its axial direction. Through the above arrangement, the water falling from the drainage pipe to the top of the buffer plate can be evenly dispersed, the movement trajectory of this part of the water can be changed, and the water in the energy dissipation pipe can collide with each other, thereby reducing the potential energy of the water falling from the drainage pipe.

[0016] The utility model also includes a drainage pipe. A funnel-shaped collecting bucket is arranged at the bottom of the energy dissipation pipe. The bottom flange of the collecting bucket is connected with a water outlet pipe. The top of the drainage pipe is fixedly sleeved on the bottom of the water outlet pipe.

[0017] In the utility model, the top of the energy dissipation pipe is connected to the bottom flange of the drainage cover.

[0018] The principle and effect of this technical solution:

[0019] Place the top of the drainage pipe just below the collecting bucket, and connect the bottom of the drainage pipe to the municipal pipe network. Then fix the drainage pipe and fix the bottom of the outlet pipe on the top of the drainage pipe. At this time, the drainage cover and the outlet pipe are both in a fixed state. Move the energy dissipation pipe horizontally so that it is stuck between the drainage cover and the outlet pipe, and connect the upper and lower ends of the energy dissipation pipe to the drainage cover and the outlet pipe flange respectively.

[0020] Through the above arrangement, after the drainage hood and the water outlet pipe are fixedly set, the energy dissipation pipe can be connected to the two and fixedly connected to the two. At the same time, when the buffer plate needs to be replaced, the energy dissipation pipe can be easily disassembled, reducing the difficulty of operation and improving work efficiency.

[0021] In the utility model, a plurality of mounting blocks are fixedly arranged at intervals along the circumference of the inner wall of the energy dissipation pipe, and the support plate is placed on the top of the mounting block and is fixedly connected to the plurality of mounting blocks by bolts. Through the above arrangement, the support plate can be fixedly arranged in the energy dissipation pipe in the horizontal direction, and the support plate can be conveniently disassembled and assembled by the staff, further reducing the maintenance cost of the utility model.

[0022] In the utility model, the diameter of the buffer plate is larger than the inner diameter of the drain pipe. Through the above arrangement, it is ensured that the water falling vertically from the drain pipe can impact the buffer plate, and part of the water is prevented from directly falling out of the energy dissipation pipe, thereby ensuring the energy dissipation effect of the utility model.

[0029] As attached Figure 1-4As shown, the utility model discloses a drainage pipe outlet discharge energy dissipation structure, including a drainage pipe 10, a drainage hood 20 and an energy dissipation pipe 30, the drainage hood 20 is connected from top to bottom, and the bottom is truncated, the top of the drainage hood 20 is fixedly sleeved on the bottom of the drainage pipe 10, the energy dissipation pipe 30 is connected from top to bottom, the top of the energy dissipation pipe 30 is detachably arranged on the bottom of the drainage hood 20, a support plate 40 is fixedly arranged in the transverse direction inside the energy dissipation pipe 30, a buffer plate 50 is detachably arranged on the support plate 40 below the drainage pipe 10, and a plurality of through grooves 41 are arranged at intervals along the circumference of the buffer plate 50 on the top of the support plate 40.

[0030] In this embodiment, a connecting rod 51 is fixedly provided at the bottom of the buffer plate 50 along its axial direction, and the connecting rod 51 is slidably inserted into the support plate 40. A compression spring 52 is sleeved between the buffer plate 50 and the support plate 40 outside the connecting rod 51. In the initial state, the lower edge of the connecting rod 51 is much lower than the lower edge of the support plate 40, so as to prevent the buffer plate 50 and the connecting rod 51 from being pushed away from the support plate 40 when the compression spring 52 is reset.

[0031] In this embodiment, a truncated cone-shaped drainage block 53 is fixedly provided on the top of the buffer plate 50 along its axial direction.

[0032] In this embodiment, a drainage pipe 60 is further included. A funnel-shaped collecting bucket 31 is provided at the bottom of the energy dissipation pipe 30 . The bottom flange of the collecting bucket 31 is connected to a water outlet pipe 70 . The top of the drainage pipe 60 is fixedly sleeved on the bottom of the water outlet pipe 70 .

[0033] In this embodiment, the top of the energy dissipation pipe 30 is connected to the bottom flange of the drainage cover 20 .

[0034] In this embodiment, a plurality of mounting blocks 32 are fixedly arranged at intervals along the circumference of the inner wall of the energy dissipation pipe 30 , and the support plate 40 is placed on the top of the mounting blocks 32 and is fixedly connected to the plurality of mounting blocks 32 by bolts.

[0035] In this embodiment, the diameter of the buffer plate 50 is greater than the inner diameter of the drain pipe 10 .

[0036] The specific implementation process is as follows:

[0037] The water is discharged downward through the drainage pipe 10 and flows into the drainage cover 20. Part of the water flows along the side wall of the drainage cover 20 and the side wall of the energy dissipation pipe 30. The remaining water directly impacts the buffer plate 50 after flowing out of the drainage pipe 10. The buffer plate 50 eliminates part of the potential energy of this part of the water and changes the flow direction of this part of the water, so that this part of the water collides with the water flowing along the side wall of the drainage cover 20 and the side wall of the energy dissipation pipe 30, further eliminating the potential energy of the water in the energy dissipation pipe 30. The water after energy dissipation falls out of the energy dissipation pipe 30 through the through groove 41. After the buffer plate 50 is damaged due to the long-term impact of the water and sediment falling from the impact of the drainage pipe 10, the energy dissipation pipe 30 is first removed, and then the buffer plate 50 in the energy dissipation pipe 30 is replaced.

[0038] When water falls from the drain pipe 10 and impacts the buffer plate 50 , the buffer plate 50 is pushed to move downward and the compression spring 52 is compressed to have elastic force.

[0039] Place the top of the drainage pipe 60 directly below the collecting bucket 31, and connect the bottom of the drainage pipe 60 to the municipal pipe network. Then fix the drainage pipe 60, and fix the bottom of the outlet pipe 70 to the top of the drainage pipe 60. At this time, the drainage hood 20 and the outlet pipe 70 are both in a fixed state. Move the energy dissipation pipe 30 horizontally so that it is stuck between the drainage hood 20 and the outlet pipe 70, and make the upper and lower ends of the energy dissipation pipe 30 flange-connected to the drainage hood 20 and the outlet pipe 70 respectively.
