Description

Technical Field

[0001] This utility model relates to the field of water intake channel diversion technology, and more specifically, to an adjustable diversion structure for a water plant intake channel. Background Technology

[0002] As the first stage in the raw water transportation process, the diversion effect of the water plant's intake channel directly impacts the treatment efficiency of subsequent sedimentation and filtration tanks. Because raw water often contains suspended solids, silt, and other impurities, and water quality varies at different depths, diversion structures are typically installed in the intake channel to achieve proper flow distribution.

[0003] In existing technologies, fixed baffles are typically used to divert water in the intake channel. This involves vertically installing baffles of a fixed height within the intake channel, with gaps between the bottom of the baffles and the channel bottom. The baffles are arranged parallel to the water flow direction, thus forming multiple diversion channels. During diversion, as water flows through the gaps at the bottom of the baffles, the flow velocity decreases, and large particles of sediment settle to the front of the baffles under gravity. Surface water overflows through the top of the baffles into the next stage of the channel, achieving the functions of sediment retention and surface diversion.

[0004] However, when the influent flow rate changes, the overflow height of surface water containing floating matter (such as leaves, grease, etc.) from the top of the baffle increases, causing surface water to be carried to deeper water. At the same time, eddies easily form in the gaps at the bottom of the baffle, causing coarse silt to accumulate, requiring periodic water outages for dredging. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable diversion structure for the water intake channel of a water plant. By driving the diversion cavity to extend into the water intake channel body or retract into the diversion pipe, the water flow can be diverted. The diversion effect is better, and there is no need to stop the water supply for dredging, thus reducing maintenance costs.

[0006] This utility model is achieved through the following technical solution: an adjustable diversion structure for a water plant intake channel, including an intake channel body and a diversion pipe group disposed on both sides of the intake channel body. The side wall of the intake channel body is provided with a diversion port, and the diversion pipe is connected to the intake channel body through the diversion port. The diversion pipe group includes multiple diversion pipes, and a diversion mechanism is provided inside the diversion pipe.

[0007] The diversion mechanism includes a diversion cavity slidably disposed within a diversion pipe and a driving component for driving the diversion cavity to slide relative to the diversion pipe, so that the diversion cavity can extend into the inlet channel body through the diversion port or retract into the diversion pipe. The diversion cavity can slide along the length direction of the diversion pipe, and the side of the diversion cavity facing the water flow direction is open. When the diversion cavity extends into the inlet channel body, the water flow in the inlet channel body is guided by the diversion cavity into the diversion pipe.

[0008] Furthermore, the diversion pipe includes an integrally formed first pipe body and a second pipe body. The diversion cavity is slidably disposed within the first pipe body. The second pipe body is connected to the side wall of the first pipe body. The two ends of the first pipe body have an inlet and a slag discharge port, respectively. The inlet is connected to the diversion port and the slag discharge port are arranged opposite to each other. The end of the second pipe body away from the first pipe body is the outlet, which is used to connect to the water inlet pipe of the water plant.

[0009] Furthermore, the diversion mechanism also includes a filter screen plate arranged along the length of the first pipe body. The filter screen plate is located on the side of the first pipe body close to the second pipe body. The water flow guided into the first pipe body by the diversion cavity flows into the second pipe body after being filtered by the filter screen plate.

[0010] Furthermore, the filter screen includes a first screen and a second screen that are nested together. One end of the first screen is fixedly connected to the diversion cavity, the other end of the first screen is sleeved on the outside of the second screen, and the end of the second screen away from the first screen is fixedly connected to the first tube.

[0011] Furthermore, the driving component is a rodless cylinder fixedly disposed within the diversion pipe. The rodless cylinder is disposed along the length direction of the first pipe body, and the sliding block of the rodless cylinder is fixedly connected to the diversion cavity.

[0012] Furthermore, both the first pipe body and the diversion cavity are inclined, the inclination angles of the first pipe body and the diversion cavity are equal, and the angle formed by the axis of the first pipe body and the diversion cavity and the axis of the inlet channel body is an acute angle.

[0013] Furthermore, a limiting block is provided on the inner wall of the inlet channel facing the diversion port to limit the diversion cavity.

[0014] Furthermore, the limiting block is provided with a guide slope that cooperates with the diversion cavity on the side facing the water flow direction of the inlet channel body.

[0015] Furthermore, a baffle for opening and closing the slag discharge port is also provided inside the first pipe.

[0016] Furthermore, the first tube body is provided with a rotating block, and a connecting shaft is fixedly provided at the bottom of the rotating block. The rotating block is fixedly connected to the baffle through the connecting shaft. The bottom of the baffle is provided with a rotating shaft, which enables the baffle to rotate relative to the first tube body. The rotating block is also provided with a pin for locking the rotation angle of the baffle.

[0017] Secondly, this utility model is achieved through the following technical solution:

[0018] As can be seen from the above, this application drives the diversion cavity to slide relative to the diversion pipe, allowing the diversion cavity to extend into the main body of the inlet channel through the diversion port, thereby guiding the water flow in the main body of the inlet channel to the diversion pipe to achieve diversion. By driving the diversion cavity to slide in the opposite direction, the diversion cavity can be retracted into the diversion pipe, thus allowing the water flow in the main body of the inlet channel to flow normally. In other words, this application can drive the diversion cavity to slide relative to the diversion pipe to extend into the main body of the inlet channel for diversion according to actual needs, or retract the diversion cavity into the diversion pipe to stop diversion. It has high flexibility, good diversion effect, facilitates the later operation of the water plant, eliminates the need for water outages and dredging, and reduces maintenance costs.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0028] The following is for reference Figures 1-6 As shown in the figure, and further explained with reference to specific embodiments, this embodiment provides an adjustable diversion structure for a water plant intake channel, including an intake channel body 10 and diversion pipe groups disposed on both sides of the intake channel body 10. The intake channel body 10 has a diversion port 11 on its side wall, and the diversion pipe 20 is connected to the intake channel body 10 through the diversion port 11. The diversion pipe group includes multiple diversion pipes 20, and a diversion mechanism 30 is disposed in the diversion pipe 20.

[0029] In this embodiment, there are two groups of diversion pipes, with multiple diversion pipes 20 in each group evenly distributed along the length of the inlet channel body 10. In other embodiments, the number of diversion pipe groups can also be four, six, eight, etc., with the diversion pipe groups on the same side of the inlet channel body 10 respectively located at different heights of the inlet channel body 10, thereby diverting the water into the inlet channel body 10 at different heights, achieving layered diversion of the inlet channel body 10, and further improving the diversion effect.

[0030] The diversion mechanism 30 includes a diversion cavity 31 slidably disposed within the diversion pipe 20 and a driving member for driving the diversion cavity 31 to slide relative to the diversion pipe 20, so that the diversion pipe 20 can extend into the inlet channel body 10 through the diversion port 11 or retract into the diversion pipe 20. The diversion cavity 31 can slide along the length direction of the diversion pipe 20. The interior of the diversion cavity 31 is hollow and has an opening on the side facing the water flow direction. The end of the diversion cavity 31 located inside the diversion pipe 20 has an opening. When the diversion cavity 31 slides relative to the diversion pipe 20 and extends into the inlet channel body 10, the water flow in the inlet channel body 10 is guided by the diversion cavity 31 into the diversion pipe 20.

[0031] Understandably, by driving the diversion cavity 31 to slide relative to the diversion pipe 20 through the driving component, the diversion cavity 31 can be extended into the water inlet channel body 10 to achieve diversion, or the diversion cavity 31 can be retracted into the diversion pipe 20 to stop diversion. The operation is simple and convenient, highly flexible, and has a good diversion effect. It is convenient for the later operation of the water plant, and there is no need to stop the water supply for dredging, which reduces maintenance costs.

[0032] Furthermore, the diversion pipe 20 includes an integrally formed first pipe body 21 and a second pipe body 22. The diversion cavity 31 is slidably disposed inside the first pipe body 21. The second pipe body 22 is connected to the side wall of the first pipe body 21. The two ends of the first pipe body 21 have an inlet 211 and a slag discharge port 212, respectively. The inlet 211 is connected to the diversion port 11. The inlet 211 and the slag discharge port 212 are arranged opposite to each other. The end of the second pipe body 22 away from the first pipe body 21 is the outlet 221, which is used to connect with the water inlet pipe of the water plant.

[0033] By setting the diversion pipe 20 as the first pipe body 21 and the second pipe body 22, the impurities in the water flow that is guided from the diversion cavity 31 to the first pipe body 21 can be discharged. At the same time, the outlet 221 of the second pipe body 22 is directly connected to the water inlet pipe of the water plant through the conveying pipe, thereby facilitating the water plant's treatment of the water flow (such as sedimentation, filtration, etc.).

[0034] Furthermore, the diversion mechanism 30 also includes a filter screen 32 arranged along the length of the first pipe body 21. The filter screen 32 is located on the side of the first pipe body 21 near the second pipe body 22. The water flow guided by the diversion cavity 31 into the first pipe body 21 is filtered by the filter screen 32 and then flows into the second pipe body 22.

[0035] Understandably, the filter screen 32 can filter the water flow, so that the water flow guided from the diversion chamber 31 to the first pipe 21 can be filtered by the filter screen 32 before flowing into the second pipe 22, and finally discharged into the water plant's inlet pipe through the outlet 221 of the second pipe 22. While diverting the water flow in the inlet channel body 10, the water flow is initially filtered, thereby preventing impurities in the water flow from being directly discharged into the water plant's inlet pipe and affecting the water plant.

[0036] Furthermore, the filter plate 32 includes a first filter plate 321 and a second filter plate 322 that are nested together. One end of the first filter plate 321 is fixedly connected to the flow distribution cavity 31, and the other end of the first filter plate 321 is fixedly fitted outside the second filter plate 322. The end of the second filter plate 322 that is away from the first filter plate 321 is fixedly connected to the first tube 21.

[0037] Understandably, by setting the filter screen 32 as a first screen 321 and a second screen 322 that are nested together, and fixing the first screen 321 and the second screen 322 to the diversion cavity and the diversion pipe 20 respectively, when the driving component drives the diversion cavity to slide relative to the first pipe body 21, it drives the first screen 321 to move synchronously. That is, when the diversion cavity 31 extends into the water inlet channel or retracts into the first pipe body 21, it drives the filter screen 32 to extend or retract synchronously, so that the filter screen 32 can continuously filter the water flow and improve the filtration effect.

[0038] Furthermore, the driving component is a rodless cylinder 33 fixedly installed inside the diversion pipe 20. The rodless cylinder 33 is arranged along the length direction of the first pipe body 21, and the sliding block of the rodless cylinder 33 is fixedly connected to the diversion cavity 31.

[0039] The flow divider 31 is driven to slide by the rodless cylinder 33, and the stroke is stable and reliable, so that the flow divider 31 can slide stably relative to the flow divider pipe 20 and extend into the water inlet channel through the flow divider port 11 or retract into the first pipe body 21.

[0040] Furthermore, both the first pipe body 21 and the diversion cavity 31 are inclined, the inclination angles of the first pipe body 21 and the diversion cavity 31 are equal, and the angle formed by the axis of the first pipe body 21 and the diversion cavity 31 and the axis of the inlet channel body 10 is an acute angle.

[0041] Understandably, by tilting the first pipe body 21 and the diversion cavity 31, and making the angle between the axis of the first pipe body 21 and the axis of the diversion cavity 31 and the axis of the inlet channel body 10 acute, the diversion effect is better than that of the first pipe body 21 and the diversion cavity 31 which are perpendicular to the inlet channel body 10.

[0042] Furthermore, a limiting block 12 for limiting the flow diversion cavity 31 is provided on the inside of the water inlet channel body 10 facing the diversion port 11.

[0043] Furthermore, the limiting block 12 is provided with a guide slope that cooperates with the diversion cavity 31 on the side facing the water flow direction in the water inlet channel body 10.

[0044] Understandably, when the diversion cavity 31 extends into the inlet channel body 10 and abuts against the limiting block 12 on the side wall of the inlet channel body 10, the limiting block 12 can limit the diversion cavity 31, so that the diversion cavity 31 is not easily deflected or deformed under the impact of water flow, thereby enabling the diversion cavity 31 to divert water stably and improve the diversion effect. The setting of the guide slope can make the diversion cavity 31 smoothly abut against the side wall of the inlet channel body 10 and the limiting block 12, avoiding the situation where the diversion cavity 31 cannot extend into the preset position and thus affect the diversion effect.

[0045] Furthermore, a baffle 213 for opening and closing the slag discharge port 212 is also provided inside the first pipe body 21.

[0046] Furthermore, a rotating block 214 is provided on the first tube 21, and a connecting shaft 215 is fixedly provided at the bottom of the rotating block 214. The rotating block 214 is fixedly connected to the baffle 213 through the connecting shaft 215. A rotating shaft 216 is provided at the bottom of the baffle 213, which allows the baffle 213 to rotate relative to the first tube 21. A pin 217 is provided on the rotating block 214 for locking the rotation angle of the baffle 213.

[0047] It should be noted that the first pipe body 21 is provided with two pin holes 218. Both pin holes 218 are used to cooperate with the pin 217. When slag discharge is required (the initial state of the slag discharge port 212 is closed by default, and the diversion cavity 31 is retracted into the first pipe body 21 at this time), first pull out the pin 217, drive the rotating block 214 to rotate 90°, drive the baffle 213 to rotate, and make the baffle 213 rotate 90°, and insert the pin 217 into the pin hole 218 to lock the rotation angle of the baffle 213. At this time, the slag discharge port 212 is opened, and the operator can insert a scraper into the first pipe to clean the impurities on the surface of the filter screen plate 32, and discharge the cleaned impurities from the slag discharge port 212. After the slag discharge is completed, pull out the pin 217 again, rotate the rotating block 214 in the opposite direction by 90°, and drive the baffle 213 to rotate back to the initial position. At this time, the slag discharge port 212 is closed, and then drive the diversion cavity 31 to extend into the water inlet channel body 10 relative to the first pipe to realize the diversion of the water inlet channel body 10.

[0048] In addition, in order to connect the rotating block 214 and the baffle 213, the top of the first pipe 21 is provided with a through hole for the connecting shaft 215 to extend into, and a sealing ring (not shown in the figure) is provided in the gap between the connecting shaft 215 and the inner wall of the through hole.

[0049] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
