Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, specifically to a water diversion structure. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Therefore, water conservancy projects are constructed to control water flow, prevent floods, and regulate and distribute water to meet the needs of human life and production. The water diversion structure in a water conservancy project is used to introduce water from rivers into channels to meet the needs of irrigation, power generation, industrial and domestic water use. The water diversion structure is located at the head of the water diversion channel and is also known as the headworks.

[0003] The current water diversion structure has certain drawbacks. When the gate is opened to divert water, floating objects on the water surface and coarse silt and other debris in the river channel are introduced into the water diversion channel through the water diversion structure. Over a long period of time, this can lead to blockage of the water diversion channel.

[0004] In existing technologies, such as the water-guiding structure proposed in Chinese Patent Application No. 202320299061.7, impurities in the water are filtered using a filter screen. To clean the impurities, a limiting block at one end of the moving tube is pulled out of the limiting hole by rotating the threaded tube, and then the insertion mounting plate is pulled out of the insertion mounting groove to clean the impurities inside the filter connecting tube. While this water-guiding structure can filter impurities in the water, cleaning the impurities inside the filter connecting tube requires disassembling the tube, which is a cumbersome process, making the entire cleaning process time-consuming and labor-intensive.

[0024] This utility model has the following beneficial effects:

[0025] 1. When the slag storage frame needs to be cleaned, the staff removes the water filtration mechanism from the water inlet channel. The scraper scrapes up the mud, sand and other small particles in the slag storage frame. As the cleaning frame is pulled out, a slag discharge port is formed between the two pull rods at the bottom of the cleaning frame and the bottom plate. The scraper pushes the mud, sand and impurities in the slag storage frame toward the slag discharge port, from which the mud, sand and impurities are discharged. After cleaning, the cleaning frame is pushed back into the slag storage frame, and then the water filtration mechanism is put back into the water inlet end of the water inlet channel to complete the cleaning of debris inside the water intake structure. It is time-saving, labor-saving and easy to operate.

[0026] 2. The scraper at the bottom of the scraper will scoop up the mud and impurities on the bottom plate, which can improve the cleaning efficiency of the cleaning frame;

[0027] 3. The pulley at the free end of the first pull rod rolls in the first slide groove, and the pulley at the free end of the second pull rod rolls in the second slide groove. This allows the cleaning frame to slide more smoothly in the slag storage frame and reduces sliding resistance.

[0028] 4. The baffle bar can block large pieces of garbage and debris such as branches in the water from entering the water filtration mechanism, preventing them from affecting the water flow. It can also prevent the cleaning frame from sliding due to garbage and debris entering the water filtration mechanism.

[0029] 5. The roller brush can brush off the mud and impurities attached to the filter screen, preventing them from clogging the filter screen and further improving cleaning efficiency.

[0030] 6. The hemispherical groove has a guiding function. When the hemispherical end of the lever is pulled by the auxiliary rod, it will slide out of the groove. The spring will hold the hemispherical end of the lever in the groove, thus fixing the auxiliary rod to the main rod.

[0031] 7. After the water filtration mechanism is pulled out from the water inlet channel, due to the alternating left and right hinge points of multiple auxiliary rods and the base plate along the length of the water inlet channel, as well as the cooperation between the clamping rod and the clamping groove, multiple support rods can support the water filtration mechanism and prevent it from descending during the cleaning process.

[0032] 8.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0046] This utility model proposes a water-diverting structure, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a water filtration mechanism 3 and a water inlet channel 2. The water filtration mechanism 3 is set at the water inlet end of the water inlet channel 2. The water filtration mechanism 3 includes a filter screen 33, a cleaning frame 31 and a slag storage frame 32. The cleaning frame 31 includes a side plate 311, a pull rod 312 and a scraper 313. The side plate 311 and the scraper 313 are arranged parallel to each other vertically. There are two pull rods 312. The two pull rods 312 are respectively fixedly connected between the bottom of the water inlet side of the side plate 311 and the bottom of the water outlet side of the scraper 313.

[0047] like Figure 3 and Figure 4As shown, the slag storage frame 32 includes a second side plate 321 and a bottom plate 322. The second side plate 321 and the bottom plate 322 are arranged perpendicular to each other. The second side plate 321 is fixedly connected to one side edge of the bottom plate 322. The filter screen 33 is fixedly installed at the water outlet end of the slag storage frame 32.

[0048] Pull rod 312 is slidably connected to the upper surface of base plate 322 in the horizontal left and right direction. Side plate 321 is set on the same side as scraper 313, and the bottom edge of scraper 313 abuts against the upper surface of base plate 322.

[0050] When the slag storage frame 32 needs to be cleaned, the staff removes the water filtration mechanism 3 from the water inlet channel 2. The scraper 313 scrapes up the mud and other small particles in the slag storage frame 32. As the cleaning frame is pulled out, a slag discharge port is formed between the two pull rods 312 at the bottom of the cleaning frame 31 and the bottom plate 322. The scraper 313 pushes the mud and impurities in the slag storage frame 32 toward the slag discharge port, and the mud and impurities are discharged from the slag discharge port. After cleaning, the cleaning frame is pushed back into the slag storage frame 32, and then the water filtration mechanism 3 is put back into the water inlet end of the water inlet channel 2 to complete the cleaning of the debris inside the water intake structure. It is time-saving, labor-saving, and easy to operate.

[0051] like Figure 2 and Figure 3 As shown, the scraper 313 is further provided with a shovel at the bottom, and the side of the shovel facing the inside of the cleaning frame 31 is a slope, with the bottom surface of the shovel abutting against the upper surface of the base plate 322.

[0052] The scraper belt at the bottom of scraper 313 will scrape up the mud and impurities on the base plate 322, thus improving the cleaning efficiency of cleaning frame 31.

[0053] like Figure 2 and Figure 3 As shown, the cleaning frame 31 further includes a second pull rod 314. Two pull rods 314 are provided, and the two pull rods 314 are respectively fixedly connected between the top of the water inlet side of the side plate 311 and the top of the water outlet side of the scraper 313.

[0054] like Figure 5 and Figure 7 As shown, the slag storage frame 32 also includes a slide bar 323. There are two slide bars 323, which are respectively fixedly connected to the top of the water inlet side and the top of the water outlet side of the side plate 321.

[0055] The two pull rods 314 are slidably connected to the two slide rods 323 in the horizontal left and right directions, respectively.

[0056] like Figure 2, Figure 3 and Figure 4 As shown, further, the bottom surface of the free end of the first pull rod 312 and the top surface of the free end of the second pull rod 314 are both provided with wheel grooves 318, and pulleys 319 are rotatably connected in the wheel grooves 318;

[0057] like Figure 5 , Figure 6 and Figure 8 As shown, the upper surface of the base plate 322 has two sliding grooves 324 along the left and right directions, and the bottom surface of the free ends of the two sliding rods 323 has a second sliding groove 325. The pulley 319 at the free end of the first rod 312 rolls in the first sliding groove 324, and the pulley 319 at the free end of the second rod 314 rolls in the second sliding groove 325.

[0058] The pulley 319 at the free end of the first pull rod 312 rolls in the first chute 324, and the pulley 319 at the free end of the second pull rod 314 rolls in the second chute 325. This allows the cleaning frame 31 to slide more smoothly in the slag storage frame 32, reducing sliding resistance.

[0059] like Figure 2 and Figure 7 As shown, further, multiple baffle rods 317 are fixedly connected between the first pull rod 312 and the second pull rod 314 located at the water inlet end of the cleaning frame 31;

[0060] like Figure 2 Figure 3 and Figure 7 As shown, a roller brush 315 is rotatably connected between the pull rod 312 and the pull rod 314 at the water outlet end of the cleaning frame 31. The roller brush 315 is located at the free end of the pull rod 312 and the pull rod 314, and the roller brush 315 abuts against the filter screen 33.

[0061] The baffle bar 317 can block large pieces of garbage and debris such as branches in the water from entering the water filtration mechanism 3, preventing large pieces of garbage and debris such as branches from entering the water filtration mechanism 3 and affecting the water flow. At the same time, it can also prevent the cleaning frame 31 from being obstructed due to garbage and debris entering the water filtration mechanism 3.

[0062] The roller brush 315 can brush off the mud and impurities attached to the filter screen 33, preventing the mud and impurities from clogging the mesh of the filter screen 33 and further improving the cleaning efficiency.

[0063] like Figure 9 As shown, multiple placement slots 21 perpendicular to the side walls of the water inlet channel 2 are provided on the bottom inner wall along its length direction. The placement slots 21 are provided with telescopic support rods 4. One end of the support rod 4 is hinged in the placement slot 21, and the other end of the support rod 4 is hinged to the bottom plate 322 of the slag storage frame 32. The hinge points of the multiple support rods 4 and the bottom plate 322 are alternately arranged on the left and right along the length direction of the water inlet channel 2.

[0064] like Figure 9 and Figure 10 As shown, the support rod 4 includes a secondary rod 41 and a main rod 42. The main rod 42 is a tubular rod, and the secondary rod 41 is sleeved inside the main rod 42. The connecting end of the main rod 42 is hinged in the placement groove 21, and the connecting end of the secondary rod 41 is hinged to the bottom plate 322 of the slag storage frame 32. The hinge points of multiple secondary rods 41 and the bottom plate 322 are alternately arranged on the left and right along the length direction of the water inlet channel 2.

[0065] like Figure 10 and Figure 11 As shown, further, a clearance groove 411 is provided on the peripheral side of the end of the auxiliary rod 41 that extends into the main rod 42. A locking rod 413 is provided in the clearance groove 411. A spring 412 is fixedly connected between the end of the locking rod 413 located in the clearance groove 411 and the bottom surface of the clearance groove 411. The end of the locking rod 413 located outside the clearance groove 411 is hemispherical.

[0066] The inner sidewall of the main rod 42 is provided with multiple slots 421 along its length. The slots 421 are hemispherical and correspond to the positions of the locking rods 413.

[0067] The hemispherical slot 421 has a guiding function. In this way, after the hemispherical end of the lever 413 is pulled by the auxiliary rod 41, it will slide out from the slot 421. The spring 412 will push the hemispherical end of the lever 413 into the slot 421, thus fixing the auxiliary rod 41 to the main rod 42.

[0068] After the water filtration mechanism 3 is pulled out from the water inlet channel 2, due to the alternating left and right hinge points of multiple auxiliary rods 41 and the base plate 322 along the length of the water inlet channel 2, and the cooperation between the locking rod 413 and the locking groove 421, multiple support rods 4 can support the water filtration mechanism 3 and prevent the water filtration mechanism 3 from falling during the cleaning process.

[0069] like Figure 1 As shown, it also includes a water collection structure 1, which includes an anti-scouring plate 11 and a water collection guide plate 12. The anti-scouring plate 11 is fixedly connected to the bottom wall of the water inlet end of the water inlet channel 2.

[0070] Two water collection guide plates 12 are provided. Both water collection guide plates 12 are fixedly connected to the anti-scouring plate 11 and are arranged in a figure-eight shape. The small opening formed between the two water collection guide plates 12 is fixedly connected to the water inlet end of the water inlet channel 2.

[0071] The two water guide plates 12 are arranged in a figure-eight shape, which can effectively gather water at the inlet end of the water inlet channel 2 and improve the water diversion efficiency of the water diversion structure. The anti-scour plate 11 can protect the original ground in front of the inlet end of the water inlet channel 2 and prevent the water flow from scouring the original ground.

[0072] Using this invention, water enters the inlet channel 2 from the water collection structure 1. As water passes through the inlet end of the inlet channel 2, the baffle rod 317 blocks large pieces of garbage and debris such as branches from the water outside the filtration mechanism 3. Then, the filter screen 33 inside the filtration mechanism 3 filters out mud, sand, and other small particulate impurities from the water, leaving these impurities in the sludge storage frame 32. When it is necessary to clean the sludge storage frame 32, the worker pulls the filtration mechanism 3 out of the inlet channel 2, the support rod 4 is pulled out of the placement groove 21, and the auxiliary rod 41 is pulled out of the main rod 42. Pulling out, due to the guiding function of the hemispherical slot 421, the hemispherical end of the lever 413 slides out of the original slot 421 after being pulled by the auxiliary rod 41. The spring 412 is compressed, and after the hemispherical end of the lever 413 enters the next slot 421, the spring 412 returns to its original position and pushes the hemispherical end of the lever 413 into the slot 421. During the process of the auxiliary rod 41 being pulled out, the hemispherical end of the lever 413 will repeat the above action until the water filter mechanism 3 is completely pulled out of the water inlet channel 2. At this time, the lever 413... 13, in conjunction with the slot 421, temporarily fixes the auxiliary rod 41 and the main rod 42. Multiple support rods 4 support the water filtration mechanism 3. Then, the worker pulls the cleaning frame 31 out of the sludge storage frame 32. The scraper 313 scrapes up the mud, sand and other small particles of impurities in the sludge storage frame 32. The shovel at the bottom of the scraper 313 scrapes up the mud, sand and impurities on the bottom plate 322. As the cleaning frame is pulled out, a sludge discharge port is formed between the two pull rods 312 at the bottom of the cleaning frame 31 and the bottom plate 322. The scraper 313 pushes the sludge storage frame 32... The mud and impurities inside move towards the slag discharge port and are discharged from the slag discharge port. At the same time, the roller brush 315 brushes off the mud and impurities attached to the filter screen 33 and discharges them from the slag discharge port. After the mud and impurities in the slag storage frame 32 are cleaned, the cleaning frame is pushed into the slag storage frame 32, and then the water filtration mechanism 3 is pressed down. The auxiliary rod 41 is pressed into the main rod 42. As the water filtration mechanism 3 descends, the support rod 4 re-enters the placement tank 21, completing the cleaning of the debris inside the water intake structure. It is time-saving, labor-saving, and easy to operate.

[0073] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
