Description

Technical Field

[0001] The present application relates to the technical field of water conservancy projects, and in particular to an open water diversion system. Background Art

[0002] When the water diversion line of a hydropower station is long, or when the unit suddenly dumps load and closes the guide vane during operation, a large water hammer effect will occur in the flow channel due to the inertia of the water flow, which can easily damage the power generation equipment. If there is no surge tank, the water hammer will destroy the guide vane and other flow-passing components. In order to release the water hammer pressure in the flow channel, a water diversion system is often used to divert the water.

[0003] In the related art, a Chinese patent with publication number CN207419417U proposes an open water diversion system for water diversion and power generation projects, which is provided with an open water diversion system including an adaptive water pressure regulating device and a water delivery pipeline, and the water delivery pipeline is provided as a steel water delivery pipeline arranged on the basis of the overburden along the water diversion route, and then the adaptive water pressure regulating device is plugged into the output end of the water delivery pipeline. In the process of water diversion and power generation, the abnormal water pressure in the water delivery pipeline is eliminated by the adaptive water pressure regulating device.

[0004] The above-mentioned related technologies have the following defects: floating debris is easy to exist in open waters. When water is diverted and transported, these debris can easily enter the water pipeline with the water flow and block the water pipeline, thereby affecting the water diversion and pressure relief use of the device. Utility Model Content

[0006] The open water diversion system provided in this application adopts the following technical solution:

[0007] An open water diversion system includes a water delivery pipeline, a flow deflector, an output pipe, a motor and an anti-blocking component. The motor is installed and fixed on the end surface outer wall of the flow deflector, and the output end of the motor extends into the flow deflector to drive and connect the anti-blocking component. The output pipe is fixedly connected to the outer wall of the flow deflector, and the output pipe is communicated with the inner cavity of the flow deflector. One end of the output pipe facing away from the flow deflector is connected to the adjacent end of the water delivery pipeline, so that the water delivery pipeline is communicated with the inner cavity of the flow deflector.

An opening is formed at one end of the debris collection cage facing away from the rotating seat, and multiple groups of drainage holes communicating with the inner cavity are formed on the outer wall of the debris collection cage.

[0009] Furthermore, the debris collecting cage is configured as a stainless steel cage, and there is a gap between two adjacent groups of the debris collecting cages.

[0010] Furthermore, the deflector includes an outer shell, a drainage pipe and a waste removal pipe, the drainage pipe and the waste removal pipe are respectively connected and arranged at the top and bottom of the outer shell, the motor is installed and fixed on the end surface outer wall of the outer shell, and the output pipe is connected to the outer shell.

[0011] Furthermore, the inner diameter of the debris collection cage is adapted to the inner diameter of the drainage pipe, the end of the debris collection cage facing away from the rotating seat is in contact with the inner wall of the outer shell, the inner diameter of the debris collection cage is also adapted to the inner diameter of the waste cleaning pipe, and the lower end of the waste cleaning pipe is detachably sealed with a sealing plug.

[0013] Furthermore, it also includes a bracket and a plurality of groups of pipe brackets, wherein the bracket is installed below the air deflector and supports and fixes the air deflector, and the plurality of groups of pipe brackets are installed below the water pipeline and supports and fixes the water pipeline.

[0014] The beneficial technical effects of the present application are as follows: by coordinating the arrangement of the guide cover, the output pipe, the motor and the anti-blocking component with the water delivery pipeline, the water delivery pipeline can prevent large floating debris in the water area from entering the water delivery pipeline during the water diversion and water delivery process, thereby making it less likely for the water delivery pipeline to be blocked during the water diversion and water delivery process;

DETAILED DESCRIPTION

[0022] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0023] Reference Figure 1 In the prior art, the open water diversion system sets the water pipeline 60 as a steel water pipeline arranged on the base of the overburden along the water diversion route, and then plugs the adaptive water pressure regulating device into the output end of the water pipeline 60. During the water diversion and power generation process, the abnormal water pressure in the water pipeline 60 is eliminated through the adaptive water pressure regulating device.

[0024] See also Figure 2 and Figure 3 In order to avoid the water pipe from being blocked during water diversion and pressure relief, the open water diversion system of the present application also includes a deflector 10, an output pipe 20, a motor 30 and an anti-blocking assembly 40. The motor 30 is fixedly mounted on the outer wall of the end face of the deflector 10, and the output end of the motor 30 extends into the deflector 10 to drive and connect the anti-blocking assembly 40, so that the anti-blocking assembly 40 can deflect and adjust the angle position in the deflector 10. The output pipe 20 is fixedly connected to the outer wall of the deflector 10, and the output pipe 20 is connected to the inner cavity of the deflector 10. One end of the output pipe 20 facing away from the deflector 10 is connected to the adjacent end of the water pipe 60, so that the water pipe 60 is connected to the inner cavity of the deflector 10. The water body that needs to be transported and discharged is pre-input into the deflector 10, and after the impurities are screened out by the anti-blocking assembly 40, the water pipe 60 is used for subsequent water diversion and pressure relief.

[0025] See also Figure 4The deflector 10 includes an outer shell 11, a drainage pipe 12 and a waste removal pipe 13. The drainage pipe 12 and the waste removal pipe 13 are connected and arranged at the top and bottom of the outer shell 11 respectively. The drainage pipe 12 is used to input water into the outer shell 11; the lower end of the waste removal pipe 13 is detachably blocked by a sealing plug, and after the sealing plug is removed, the debris collected in the anti-blocking component 40 can be cleaned from the waste removal pipe 13. The motor 30 is fixed on the outer wall of the end surface of the outer shell 11, the output pipe 20 and the outer shell 11 are connected to each other, and the anti-blocking component 40 is rotatably arranged in the inner cavity of the outer shell 11.

[0026] See also Figure 5 The anti-blocking assembly 40 may include a rotating seat 41, a plurality of groups of debris collection cages 42 and an annular cover 44. The middle portion of the rotating seat 41 is fixedly connected to the output end of the motor 30, and a plurality of groups of debris collection cages 42 are fixed on the outer wall of the rotating seat 41 along the radial direction thereof, so that the debris collection cages 42 and the rotating seat 41 can be deflected with the drive of the motor 30, and the debris collection cages 42 facing the drainage pipe 12 can be adjusted. An opening is formed at one end of the debris collection cage 42 facing away from the rotating seat 41, and a plurality of groups of drainage holes 43 communicating with the inner cavity are formed on the outer wall of the debris collection cage 42. The inner diameter of the debris collection cage 42 matches the inner diameter of the drainage pipe 12. The end of the debris collection cage 42 facing away from the rotating seat 41 contacts the inner wall of the outer shell 11. There is a gap between two adjacent groups of debris collection cages 42, so that the water input from the drainage pipe 12 can flow into the debris collection cage 42, and the water flows out from the drainage holes 43 into the outer shell 11 until the liquid level is higher than the output pipe 20 and can be discharged through the water delivery pipe 60. Debris during drainage can be trapped in the debris collection cage 42. After each water diversion and pressure relief, the rotating seat 41 can be driven to deflect at a fixed angle, and another group of debris collection cages 42 can face the drainage pipe 12, so that the water can flow smoothly through the anti-blocking component 40 during subsequent water diversion and pressure relief. The inner diameter of the debris collection cage 42 is matched with the inner diameter of the drainage pipe 12. After each group of debris collection cages 42 is used once, the sealing plug at the waste cleaning pipe 13 can be removed, and each group of debris collection cages 42 can be rotated toward the waste cleaning pipe 13 to guide the debris downward. The annular cover 44 is sleeved on the outside of several groups of debris collection cages 42 and fixedly connected thereto. The outer diameter of the annular cover 44 is matched with the inner diameter of the outer shell 11, so that when the rotating seat 41 deflects to each group of debris collection cages 42 no longer facing the drainage pipe 12, the annular cover 44 can be used to block the drainage pipe 12, which can prevent water from entering and can be used in situations where maintenance and other shutdowns are required. The debris collection cage 42 is set as a stainless steel cage so that the debris collection cage 42 can reduce rust damage during use.

[0027] In this embodiment, a bracket 50 and a plurality of pipe brackets 70 may also be included. The bracket 50 is installed below the deflector 10 and is used to support and fix the deflector 10; the plurality of pipe brackets 70 are installed below the water pipe 60 at intervals along the length direction of the water pipe 60 and are used to support and fix the water pipe 60.

[0028] The system of the present invention may also include a control system for controlling the operation of the motor to automatically remove debris from the water body. It should be understood that the control system has no particular limitations and can be implemented by the control technology under the prior art, which will not be described in detail here.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
