Description

Technical Field

[0001] This utility model belongs to the field of municipal pipeline technology, and more specifically, it relates to a municipal diversion and flood discharge pipeline structure. Background Technology

[0002] The laying of municipal flood discharge pipelines involves the comprehensive application of urban planning, water conservancy engineering, materials science, and construction technology. It aims to efficiently drain rainwater, prevent urban flooding, and also consider environmental protection and sustainable development. Flood discharge pipelines are used for drainage, rapidly diverting rainwater during heavy rains or floods to reduce pressure on urban drainage systems and prevent flooding.

[0003] Currently, the number of main flood discharge pipelines installed is limited. In case of extreme weather or urban terrain constraints, it is necessary to divert the main pipeline for discharge. However, due to the large water pressure impact during the drainage process in the main pipeline, the diversion pipe is easily damaged at the turning point, which can lead to pipe bursts. In addition, impurities can easily accumulate at the turning point during long-term discharge, causing blockages.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a municipal diversion and flood discharge pipeline structure in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a municipal diversion and flood discharge pipeline structure to solve the issues that diversion pipes are easily damaged at turning points, which can lead to pipe bursts, and that impurities can easily accumulate at turning points and cause blockages during long-term discharge.

[0006] The purpose and function of this utility model's municipal diversion and flood discharge pipeline structure are achieved through the following specific technical means:

[0007] A municipal diversion and flood discharge pipeline structure includes a main pipeline, a diversion port is provided on one side of the main pipeline, the diversion port is connected to a diversion pipe through a valve, a pressure relief pipe head is provided at the front end of the diversion pipe, a cap is provided at the end of the pressure relief pipe head, a pressure relief mechanism is provided inside the pressure relief pipe head, the pressure relief mechanism includes an inclined guide plate, the guide plate is slidably locked inside the pressure relief pipe head, and the guide plate is connected to the cap through an elastic structure.

[0008] Furthermore, the elastic structure includes a spring, and a connector is provided at the rear end of the guide plate. The end of the connector forms a head, and the head is connected to the cover by the spring.

[0009] Furthermore, the protrusion on the periphery of the end forms a ring surrounding one end of the spring, and a limiting post is provided inside the cover, the limiting post extending into the inner ring of the spring.

[0010] Furthermore, the transition section between the connector and the end is recessed, and a sealing sleeve is fitted in the recess, the sealing sleeve abutting against the inner wall of the pressure relief pipe head.

[0011] Furthermore, the bottom of the bend in the steering pipe is recessed downward to form a slag discharge funnel, and a threaded outlet is provided at the bottom of the slag discharge funnel, with a plug installed on the threaded outlet.

[0012] Furthermore, the cover has at least one vent hole.

[0013] Furthermore, a bracket is installed on the steering tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By setting a pressure relief pipe head on the diversion pipe, when the valve is opened, the water flows from the main pipe into the diversion pipe. The water flow impacts the guide plate and deflects the water. The guide plate moves during the impact and is depressurized through the elastic structure. While guiding the water flow to change direction, it can also buffer the impact and reduce the impact damage to the diversion pipe. In addition, the flat slope and movable setting of the guide plate reduce the accumulation of impurities at the diversion point. Most impurities are carried away with the water flow, reducing the possibility of blockage. Attached Figure Description

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 2 As shown:

[0025] This utility model provides a municipal diversion and flood discharge pipeline structure, including a main pipeline 1 for municipal flood discharge and drainage. When there is a lot of rain, the gate is opened to discharge water. A diversion port 2 is set on one side of the main pipeline 1. The diversion port 2 is connected to the diversion pipe 4 through a valve 3. The figure shows a structural schematic diagram of the diversion point. If extreme weather or urban terrain restrictions cause water accumulation or flooding, and the drainage of the main pipeline 1 is too concentrated, it is necessary to divert the main pipeline 1 for discharge. Then, the valve 3 is opened to allow some water to enter the diversion pipe 4 for diversion.

[0026] A bracket 6 is installed on the turning pipe 4. Since the main pipe 1 has a large diameter, the pits excavated before the main pipe 1 is buried underground are of the same height. The bracket 6 can support the turning pipe 4 so that it matches the position of the main pipe 1, reducing the amount of excavation and filling work during construction.

[0027] The front section of the diverting pipe 4 is extended to be provided with a pressure relief pipe head 5. The end of the pressure relief pipe head 5 is provided with a cap 10. The pressure relief pipe head 5 is provided with a pressure relief mechanism. The pressure relief mechanism includes an inclined guide plate 802. The guide plate 802 is slidably locked in the pressure relief pipe head 5. When the water flows through the turning point of the diverting pipe 4, it impacts the guide plate 802 and turns. The guide plate 802 is movable to avoid excessive impact force and damage to the guide plate 802. The inclined flat surface of the guide plate 802 can change the direction of water flow and impurities, and reduce the accumulation of impurities at the turning point.

[0028] The guide plate 802 is connected to the cover 10 through an elastic structure, which includes a spring 804. A connector 803 is provided at the rear end of the guide plate 802. The end of the connector 803 forms an end 805. The end 805 is connected to the cover 10 through the spring 804. When the guide plate 802 is impacted, the guide plate 802 moves and transmits the impact force to the spring 804 through the connector 803. The spring 804 is compressed to buffer the impact and reduce the impact damage to the steering tube 4.

[0029] The protrusion on the periphery of end 805 forms a ring surrounding one end of spring 804, such as Figure 2 As shown, a limiting post 806 is provided inside the cover 10. The limiting post 806 extends into the inner ring of the spring 804. The end 805 and the limiting post 806 limit the spring 804 from the outer ring and inner ring of the spring 804 respectively, so as to prevent the spring 804 from tilting due to excessive impact force, resulting in poor buffering effect.

[0030] In addition, the transition section between the connector 803 and the end 805 is recessed, and a sealing sleeve 801 is fitted in the recessed area. The sealing sleeve 801 abuts against the inner wall of the pressure relief pipe head 5. Since the guide plate 802 is impacted by the main water flow, water is prevented from seeping out through the guide plate 802. At least one vent hole 11 is provided on the cover 10, so that when the sealing sleeve 801 moves with the connector 803, the air pressure inside the pressure relief pipe head 5 is too high.

[0031] If long-term drainage causes garbage and impurities to accumulate at the bend of the diversion pipe 4, the bottom of the bend of the diversion pipe 4 will be recessed downward to form a slag discharge funnel 9. The bottom of the slag discharge funnel 9 is provided with a threaded outlet, and a discharge plug 7 is installed on the threaded outlet. By removing the discharge plug 7, the garbage and impurities at the bend can be cleaned from below the slag discharge funnel 9.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
