Description

Technical Field

[0001] This utility model relates to the field of water diversion structure technology, and in particular to a water diversion structure for water conservancy and hydropower projects. Background Technology

[0002] In water conservancy and hydropower projects, the water diversion structure (or water diversion system) is a crucial component. Its core task is to safely, efficiently, and controllably transport water from the water source (such as a reservoir or river) to the hydropower station or the area in need of water.

[0003] Water diversion channels are common water diversion structures, often used in low-head, high-flow-rate hydroelectric power stations or irrigation projects. However, water diversion channels tend to accumulate garbage and floating debris at bends (turns). This is because at bends, water and garbage are affected by centrifugal force and thrown to the outside of the bend. Water flows smoothly and can turn smoothly along the concave bank of the channel, while garbage is more affected and will accumulate in the corner of the concave bank. When too much garbage and debris accumulates, it will seriously affect the water flow speed and flow rate of the bend in the water diversion channel.

[0004] Current water diversion channel structures typically install filtration devices on straight sections, while bends, where debris and waste are more likely to accumulate, are often overlooked. Existing filtration devices are not compatible with the bends in existing water diversion channel structures, thus requiring a new type of water diversion channel structure to solve the current problems. Utility Model Content

[0005] This utility model addresses the aforementioned problems by providing a water diversion structure for water conservancy and hydropower projects. It adds a collection trough to the outside of a traditional bend in the canal, allowing the garbage accumulated at the bend to be flushed into the collection trough for temporary storage. The garbage accumulation in the collection trough has a minimal impact on the water flow inside the bend, effectively solving the problem of reduced water flow speed and volume caused by garbage accumulation inside the bend, and facilitating subsequent cleaning operations.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: a water diversion structure for water conservancy and hydropower projects, including a curved water channel, a trough, a collection trough, a grid and a filter screen. The curved water channel has a trough on its outer side, the collection trough is integrally connected to the trough, the grid is connected inside the collection trough, the grid is close to the outer wall of the curved water channel, and the filter screen is rotatably connected to the bottom of the collection trough, the filter screen cooperates with the grid.

[0007] Furthermore, it also includes a connecting frame, a rotating drum, and a pull rope. The connecting frame is fixedly connected to the upper side of the collection tank, the rotating drum is rotatably connected to the upper side of the connecting frame, and the pull rope is wound around the rotating drum. The end of the pull rope is fixedly connected to the filter screen.

[0008] Furthermore, it also includes a ratchet, a pawl, a push rod, and a spring. The ratchet is coaxially fixed to the rotating drum, the pawl is slidably connected to the connecting frame, the push rod is fixed to the pawl and passes through the connecting frame, the push rod is slidably connected to the connecting frame, and the spring is sleeved on the pawl.

[0009] Furthermore, it also includes: the grid is arc-shaped, the arc of the grid matches the arc of the bend in the water channel, and multiple one-way stops are evenly connected to the upper side of the grid, with the one-way stops arranged in a "7" shape.

[0010] Furthermore, it also includes: sliding grooves are provided on both sides of the collection tank, and the grid is detachably connected to the collection tank through the sliding grooves.

[0011] The beneficial effects of this utility model are as follows: This utility model opens a trough on the outside of a curved water channel and connects a collection trough integrally at the trough. When garbage and debris accumulate at the bend of the curved water channel, they are flushed into the collection trough by the water flow. When a certain amount of garbage and debris accumulates in the collection trough, a rotating filter screen scoops the garbage out of the collection trough, and then cleaning is performed. This utility model adds a collection space to the outside of the traditional curved water channel, allowing the garbage accumulated at the bend to be flushed into the collection trough for temporary storage. The garbage accumulation in the collection trough has a smaller impact on the water flow inside the curved water channel, effectively solving the problem of reduced water flow speed and flow rate caused by garbage accumulation inside the curved water channel, and facilitating subsequent cleaning operations.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] like Figures 1-4 As shown, this embodiment provides a water diversion structure for water conservancy and hydropower projects, including a curved water channel 1, a trough 2, a collection trough 3, a grid 4, and a filter screen 5. The curved water channel 1 has a trough 2 on its outer side. The collection trough 3 is integrally connected to the trough 2. The grid 4 is connected inside the collection trough 3 and is close to the outer wall of the curved water channel 1. The filter screen 5 is rotatably connected to the bottom of the collection trough 3 and cooperates with the grid 4.

[0019] In the above embodiments, by opening a slot 2 on the outside of the curved water channel 1 and integrally connecting a collection tank 3 at the slot 2, when garbage and debris accumulate at the bend of the curved water channel 1, they are flushed into the collection tank 3 by the water flow. When the garbage and debris in the collection tank 3 accumulate to a certain amount, the rotating filter screen 5 scoops the garbage out of the collection tank 3, and then cleaning is performed. By adding a collection tank 3 to the outside of the traditional curved water channel 1, the garbage accumulated at the curved water channel 1 is flushed into the collection tank 3 by the water flow and temporarily stored. The garbage accumulation in the collection tank 3 has little impact on the water flow inside the curved water channel 1, effectively solving the problem of reduced water flow speed and flow rate caused by garbage accumulation inside the curved water channel 1, and facilitating subsequent cleaning operations.

[0020] Specifically, it also includes a connecting frame 6, a rotating drum 7, and a pull rope 8. The connecting frame 6 is fixedly connected to the upper side of the collection tank 3, the rotating drum 7 is rotatably connected to the upper side of the connecting frame 6, the pull rope 8 is wound around the rotating drum 7, and the end of the pull rope 8 is fixedly connected to the filter screen 5.

[0021] In the above embodiments, rotating the drum 7 causes the pull rope 8 to retract, and the retraction of the pull rope 8 causes the filter screen 5 to rotate, thereby scooping up the garbage in the collection tank 3 for easy manual cleaning.

[0022] Specifically, it also includes a ratchet 9, a pawl 10, a push rod 11, and a spring 12. The ratchet 9 is coaxially fixed to the rotating drum 7. The pawl 10 is slidably connected to the connecting frame 6. The push rod 11 is fixed to the pawl 10 and then passes through the connecting frame 6. The push rod 11 is slidably connected to the connecting frame 6. The spring 12 is sleeved on the pawl 10.

[0023] In the above embodiments, the ratchet 9 and pawl 10 mechanism enable the one-way locking operation of the rotating drum 7, which facilitates the fixing operation after the filter screen 5 rotates, allowing the operator to focus on the cleaning operation.

[0024] Specifically, it also includes: the grid 4 is set in an arc shape, the arc of the grid 4 matches the arc of the curved water channel 1, and multiple one-way stops 13 are evenly connected to the upper side of the grid 4, with the one-way stops 13 set in a "7" shape.

[0025] In the above embodiments, the grid 4 is set to be arc-shaped, which fits the curvature of the curved water channel 1, reducing the impact of the grid 4 on the water flow. The one-way baffle 13 set in the figure-7 shape can effectively prevent garbage from flowing back into the water channel. The height of the grid 4 and the one-way baffle 13 is selected according to the water flow of the actual installation environment, so that the upper end of the one-way baffle 13 is basically flush with the horizontal plane.

[0026] Specifically, it also includes: sliding grooves 14 are provided on both sides of the collection tank 3, and the grid 4 is detachably connected to the collection tank 3 through the sliding grooves 14.

[0027] In the above embodiments, the groove 14 allows the grid 4 to be detachably connected. After the grid 4 has been used for a period of time and becomes clogged, the grid 4 can be pulled out for cleaning.

[0028] The working principle of this utility model is as follows: the garbage moves with the water flow in the bend channel 1, and most of the garbage will accumulate on the concave bank of the bend channel 1. When the garbage accumulates to a certain amount, due to the flushing effect of the water flow, the garbage will be flushed into the collection tank 3. The "7"-shaped one-way baffle 13 prevents the garbage in the collection tank 3 from flowing back into the bend channel 1. When the garbage in the collection tank 3 accumulates to a certain amount, the rotating drum 7 is rotated, the ratchet 9 rotates in one direction and locks with the pawl 10, the pull rope 8 tightens and drives the filter screen 5 to rotate, and the filter screen 5 picks up the garbage in the collection tank 3 for regular cleaning.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
