A spillway mechanism for hydraulic engineering

Abstract

This utility model discloses a spillway mechanism for water conservancy projects. A rotating circular frame is rotatably connected to the upper left side of the dam body. A filter circular frame is fixedly connected inside the rotating circular frame. An extrusion circular plate is slidably connected inside the filter circular frame. A guide frame is fixedly connected to the upper left end of the dam body. A debris removal conveyor belt is rotatably connected to the lower end of the guide frame. This utility model uses the filter circular frame to filter floating debris and other impurities carried in the water flow. The rotating circular frame is rotated by a stepper motor, causing the filter circular frame containing impurities to rotate as well. After rotating to the upper end, the ball bearings are pressed by the top pressure plate, causing the pressure-bearing movable block, sliding rod, and extrusion circular plate to be squeezed and moved to the left. This pushes the floating debris and other impurities to the upper end of the debris removal conveyor belt, which automatically discharges the debris to the bank for filtration and collection of impurities in the water.

Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a spillway mechanism for water conservancy projects. Background Technology

[0002] Dam body orifice discharge is a method of releasing reservoir water into the downstream area through orifices or pipes located inside the dam body with the inlet submerged underwater. It is mainly used for tasks such as flood discharge, water supply, sediment removal, reservoir emptying, and construction diversion. Concrete dams often use this type of discharge orifice, which can control the discharge flow in real time. According to the location, it is divided into middle orifices and bottom orifices, and according to the flow state, it is divided into pressurized discharge orifices and unpressurized discharge orifices.

[0003] An existing spillway mechanism for hydraulic engineering, with publication number CN222614123U, can collect and retrieve debris using a combination of a retrieval rod and a separation rod. It also incorporates a limiting component, allowing for the assembly and disassembly of the net using a combination of an insertion rod and a slot. However, while this device and other existing comparative documents can filter and collect debris through the orifice, they cannot automatically guide the collected floating debris, leading to continuous accumulation of debris inside the collection structure. This necessitates repeated manual cleaning, reducing the convenience of debris handling. Furthermore, this device and existing spillway mechanisms lack a buffer mechanism at the outlet, causing the discharged water to directly impact the bottom of the dam and the riverbed soil, potentially damaging the dam and reducing its service life. Therefore, a new spillway mechanism for hydraulic engineering is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a spillway mechanism for hydraulic engineering to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spillway mechanism for water conservancy projects, comprising a dam body and a spillway pipe, wherein a rotating circular frame is rotatably connected to the upper left side inside the dam body, a filter circular frame is fixedly connected inside the rotating circular frame, an extrusion circular plate is slidably connected inside the filter circular frame, a guide frame is fixedly connected to the upper left end of the dam body, and a waste removal conveyor belt is rotatably connected to the lower end inside the guide frame;

[0006] The lower inner side of the dam body is sealed with a discharge pipe. A fixing plate is fixedly connected to the outer side of the lower right end of the discharge pipe. A telescopic rod is fixedly connected to the outer side of the right end face of the fixing plate. A semi-circular buffer plate is fixedly connected to the right end of the movable inner rod of the telescopic rod.

[0007] Preferably, a discharge port and a debris discharge port are respectively provided on the upper side of the left end face of the dam body, and the position and size of the discharge port and the debris discharge port correspond to the position and size of the filter circle.

[0008] Preferably, a stepper motor is fixedly connected to the upper inner side of the dam body near the middle position, and a pulley assembly is fixedly connected to the left end of the output shaft of the stepper motor. The pulley assembly is rotatably connected to the dam body, and the inner pulley of the pulley assembly is fixedly connected to the rotating circular frame.

[0009] Preferably, a sliding rod is slidably connected to the outer side of the right end face of the rotating circular frame, the sliding rod is fixedly connected to the extrusion circular plate, a pressure-bearing movable block is fixedly connected to the right end of the sliding rod, a first spring is sleeved on the right side surface of the sliding rod, and a ball bearing is rotatably connected inside the pressure-bearing movable block.

[0010] Preferably, a top pressure slope plate is provided on the upper right side of the rotating circular frame, the top pressure slope plate is fixedly connected to the dam body, and the top pressure slope plate is rolledly connected to the ball bearings.

[0012] Preferably, an anti-scour slope plate is fixedly connected to the lower right end of the dam body, and a fixed support rod is fixedly connected between the dam body and the fixed plate.

[0013] Preferably, a second spring is sleeved on the inner movable rod surface of the telescopic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The spillway mechanism used in this water conservancy project allows water to enter a rotating circular frame through the spillway outlet and then be discharged through the spillway pipe at the lower end. The filtering circular frame filters out floating debris and other impurities carried in the water. The rotating frame is driven by a stepper motor, causing it to rotate. When the frame reaches the top, the ball bearings are pressed by the top pressure plate, causing the pressure-bearing movable block, sliding rod, and extrusion plate to be squeezed and moved to the left. This pushes the floating debris to the top of the waste removal conveyor belt. The waterproof motor drives the conveyor belt to automatically discharge the debris to the bank, facilitating the filtration and collection of impurities in the water.

[0016] 2. The spillway mechanism used in this water conservancy project discharges water through the spillway pipe. The water first impacts the semi-circular buffer plate. The arc surface on the left side of the semi-circular buffer plate can disperse the water flow. After the semi-circular buffer plate is impacted, the telescopic rod will stretch, and the internal second spring will stretch, thereby buffering the discharged water flow. In addition, the anti-scour slope plate can resist the impact of the river channel at the bottom of the dam, preventing the dam from being impacted by the water flow for a long time and reducing the service life of the dam.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please refer to Figure 1-6 As shown, this utility model provides a spillway mechanism for water conservancy projects, including a dam body 1 and a spillway pipe 7. A rotating circular frame 2 is rotatably connected to the upper left side inside the dam body 1. A filter circular frame 3 is fixedly connected inside the rotating circular frame 2. An extrusion circular plate 4 is slidably connected inside the filter circular frame 3. The rotating circular frame 2 can drive the filter circular frame 3 containing impurities to rotate. After rotating to the upper side, the extrusion circular plate 4 can squeeze the impurities out from its inner side, so as to facilitate the filtration and discharge of impurities. A guide frame 5 is fixedly connected to the upper left end of the dam body 1. A discharge conveyor belt 6 is rotatably connected to the lower end of the guide frame 5. The discharge conveyor belt 6 can guide the discharged impurities, so that the impurities can be transported to the bank for centralized collection and treatment.

[0027] The lower inner side of the dam body 1 is sealed with a discharge pipe 7. The lower right end of the discharge pipe 7 is fixedly connected to a fixing plate 8. The right end face of the fixing plate 8 is fixedly connected to a telescopic rod 9. The right end of the movable rod inside the telescopic rod 9 is fixedly connected to a semi-circular buffer plate 10. The semi-circular buffer plate 10 can disperse the water flow.

[0028] Specifically, a spillway 11 and a debris discharge outlet 12 are respectively provided on the upper side of the left end face of the dam body 1. The position and size of the spillway 11 and the debris discharge outlet 12 correspond to the position and size of the filter frame 3. The spillway 11 can be used to discharge water, while the debris discharge outlet 12 can be used to discharge debris.

[0029] Specifically, a stepper motor 13 is fixedly connected to the upper part of the dam body 1 near the middle position. A pulley group 14 is fixedly connected to the left end of the output shaft of the stepper motor 13. The pulley group 14 is rotatably connected to the dam body 1. The inner pulley of the pulley group 14 is fixedly connected to the rotating circular frame 2. The rotation of the stepper motor 13 enables the pulley group 14 to rotate. The rotation of the pulley group 14 can drive the rotating circular frames at multiple discharge holes to rotate simultaneously.

[0030] Specifically, a sliding rod 15 is slidably connected to the outer side of the right end face of the rotating circular frame 2. The sliding rod 15 is fixedly connected to the extrusion circular plate 4. A pressure-bearing movable block 16 is fixedly connected to the right end of the sliding rod 15. A first spring 17 is sleeved on the right side surface of the sliding rod 15. A ball bearing 18 is rotatably connected inside the pressure-bearing movable block 16. A top pressure slope plate 19 is provided on the upper right side of the rotating circular frame 2. The top pressure slope plate 19 is fixedly connected to the dam body 1. The top pressure slope plate 19 is rotatably connected to the ball bearing 18. The rotation of the rotating circular frame 2 can drive the ball bearing 18 to rotate. After the ball bearing 18 moves onto the top pressure slope plate 19, it can be squeezed, thereby causing the ball bearing 18 to be squeezed and move to the left, and drive the sliding rod 15 and the extrusion circular plate 4 to move to the left, so that the extrusion circular plate 4 can squeeze out the impurities in the filter circular frame 3.

[0031] Specifically, a waterproof motor 20 is fixedly connected to the lower left rear side of the guide frame 5. The output shaft of the waterproof motor 20 is fixedly connected to the internal roller shaft of the waste removal conveyor belt 6. The waterproof motor 20 can be waterproofed and can drive the waste removal conveyor belt 6 to rotate.

[0032] Specifically, an anti-scour slope plate 21 is fixedly connected to the lower right end of the dam body 1. The anti-scour slope plate 21 can resist the impact of the water flow rushing towards the bottom of the river channel of the dam body 1, and prevent the river channel from being damaged by impact. A fixed support rod 23 is fixedly connected between the dam body 1 and the fixed plate 8. The fixed support rod 23 can improve the stability of the fixed plate 8.

[0033] Specifically, a second spring 22 is sleeved on the inner movable rod surface of the telescopic rod 9, which can buffer the discharged water flow through the action of the second spring 22.

[0034] Working Principle: This utility model is a spillway mechanism for water conservancy projects. In use, water first flows through the spillway 11 and enters the filter frame 3 below the rotating frame 2. The filter frame 3 filters impurities carried in the water. The rotating frame 2 is rotated by the stepper motor 13, and the pulley group 14 causes the rotating frames 2 at multiple spillway 11 inside the dam body 1 to rotate simultaneously. The rotation of the rotating frame 2 drives the ball bearings 18 to rotate. When the ball bearings 18 move onto the top pressure slope plate 19, they are squeezed, causing them to move to the left. This squeezes the sliding rod 15 and the extrusion plate 4 to move to the left, allowing the extrusion plate 4 to squeeze out impurities from the filter frame 3. The impurities fall onto the upper end of the discharge conveyor belt 6, which is then rotated by the waterproof motor 20. The impurity discharge conveyor belt 6 can automatically discharge impurities to the bank, facilitating the filtration and collection of floating debris and other impurities. When the rotating circular frame 2 moves the ball bearing 18 downwards, the first spring 17 extends, allowing for the continuous discharge of large quantities of impurities without the need to consider impurity storage space. After filtration, the water can be discharged through the drain pipe 7. When the water is discharged, it impacts the semi-circular buffer plate 10, which disperses the water flow through its left arc surface. The impact force of the water flow causes the semi-circular buffer plate 10 to move to the right, stretching the telescopic rod 9 and compressing the internal second spring 22, thereby buffering the water flow and preventing the high-impact water flow from impacting the dam body 1 and the river channel, thus enhancing the protection of the dam body 1. Furthermore, the anti-scour slope plate 21 can resist the impact of the water flow dispersed to the lower side, greatly extending the service life of the dam body 1.
