Description

Technical Field

[0001] This utility model relates to the technical field of pollution interception devices, and in particular to an automated pollution interception device for river inlet gates. Background Technology

[0002] River intake gates are important structures in water conservancy projects, typically located at the junction of rivers with water diversion channels, pumping stations, or water treatment facilities. Their main functions include water volume regulation, water diversion guidance, and flood control and drainage. Because rivers often contain large amounts of floating debris or other pollutants, debris interception devices are usually installed on the intake side of the river intake gate to prevent these contaminants from clogging the gates.

[0003] Traditional river intake gates are mostly equipped with fixed trash racks or simple cleaning devices to intercept debris. They primarily rely on manual inspections to periodically clean floating objects or other debris. Manual cleaning is time-consuming and labor-intensive, resulting in low efficiency. Secondly, traditional trash racks face the problem of debris accumulation over long-term operation. Debris easily adheres to the rack walls, gradually forming a dense layer of grime. This not only reduces the effective water flow area between the racks but can also completely block the gaps, thus affecting the overall flow of water. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automated pollution interception device for river inlet gates.

[0005] The technical solution of this utility model is as follows:

[0006] An automated debris-blocking device for a river intake gate includes a debris-blocking grid installed behind the river intake gate. The debris-blocking grid comprises a fixed frame and multiple sets of vertically arranged grid plates. The multiple sets of grid plates are horizontally and equidistantly fixed to the rear side of the fixed frame. A debris-cleaning assembly is installed behind the debris-blocking grid. The debris-cleaning assembly includes two sets of support seats and two sets of screen plates symmetrically arranged on the left and right sides of the river. The two sets of support seats are respectively fixed to the banks on the left and right sides of the river. The upper ends of the two sets of screen plates are hinged to the two sets of support seats. Each of the two sets of support seats is connected to a drive component one for driving the screen plate to flip. The inside of the trash rack is equipped with a cleaning assembly for cleaning the side wall of the rack. The cleaning assembly includes multiple sets of blades, which are located between two adjacent sets of racks. One side of each blade is detachably connected to an L-shaped frame. The upper end of the L-shaped frame is fixedly connected to a vertical pole. The upper ends of the multiple vertical poles are detachably mounted on the support frame. One side of the support frame is equipped with a drive component two for driving the support frame to rise and fall.

[0007] Optionally, the screen plate is composed of multiple long screen bars arranged parallel to each other along the width of the river channel. The distance between two adjacent sets of long screen bars is equal to the width of a single long screen bar. When the left and right sets of screen plates are parallel to the river water surface, the free ends of the two sets of screen plates are staggered. Side guard plates are fixedly connected to the upper surfaces of the long screen bars located at the front and back sides. The upper ends of the multiple long screen bars are fixedly connected to a feed plate.

[0008] Optionally, a rotating seat is fixedly connected to the upper side of multiple sets of the long screen bars, and a shaft is fixedly connected to the front and rear ends of the rotating seat. Both sets of shafts are rotatably connected to the upper inner side of the support seat.

[0009] Optionally, the drive component one includes a sprocket one, a motor one, and a sprocket two. The sprocket one is fixedly sleeved on the outside of one set of shafts. The motor one is fixedly mounted on one side of the support base. The sprocket two is fixedly sleeved on the outside of the output shaft of the motor one. A synchronization chain is sleeved on the outside of the sprocket one and the sprocket two together.

[0010] Optionally, the cutting tool includes a fixed base and four sets of cutting tools. The four sets of cutting tools are detachably installed on the upper and lower surfaces of the fixed base on the left and right sides respectively. The upper and lower surfaces of the fixed base are symmetrically provided with slots. Each set of cutting tools consists of an insert plate and a scraper. The scraper and the insert plate are fixedly connected at an obtuse angle. The insert plate is movably inserted into the slot and the two are fixed by bolts. The side of the four sets of scrapers away from the insert plate is in contact with the side wall of the grid plate.

[0011] Optionally, the front and rear sides of the fixing base are provided with through slots, and the transverse side ends of the L-shaped frame are fixedly connected to fixing blocks. The fixing blocks are movably inserted into the through slots and the two are fixed by bolts.

[0012] Optionally, the support frame includes an upper crossbeam and a lower crossbeam. The surface of the upper crossbeam has multiple sets of equidistant limiting holes, and the surface of the lower crossbeam has multiple sets of equidistant positioning holes. A vertical pole is fixedly connected to the upper end of the vertical side of the L-shaped frame. The upper end of the vertical pole has positioning holes and limiting holes running through it from bottom to top. Two sets of fixing nuts are threaded on the outer side of the vertical pole. The two sets of fixing nuts abut against the upper and lower surfaces of the upper crossbeam, respectively. Side blocks are fixedly provided at both the left and right ends of the upper and lower crossbeams.

[0013] Optionally, the second driving component includes two sets of columns, a set of lead screws, and a set of motors. The two sets of columns are fixedly connected to the banks on the left and right sides of the river channel, respectively. A guide block is fixedly connected to one side of each of the two sets of side blocks. A guide groove is fixedly connected to the rear side of each of the two sets of columns. The two sets of guide blocks are slidably connected to the inner side of the guide grooves at corresponding positions. Two sets of horizontal plates distributed vertically are fixedly connected between the two sets of columns. The lead screw is rotatably connected to the center position of the upper surface of the lower horizontal plate. The upper end of the lead screw rotatably passes through the upper horizontal plate and is fixedly connected to the output shaft of the motor. The motor is fixedly installed on the upper surface of the upper horizontal plate by a fixing bracket. A nut seat is threaded on the outer side of the lead screw. Connecting rods are fixedly connected to both sides of the nut seat. A fixing plate is fixedly connected to the side of the connecting rod near the support frame. The fixing plate is fixedly connected to the front side of the upper and lower horizontal beams.

[0014] All of the above optional technical solutions can be combined arbitrarily, and this utility model does not provide a detailed description of the structure after each combination.

[0015] The beneficial effects of this utility model through the above solution are as follows:

[0016] 1. By incorporating a cleaning assembly, two sets of drive components simultaneously rotate two sets of screens towards the center of the river, thereby scooping up floating debris and sludge. As the screens continue to rotate, the floating debris and sludge are dumped onto the sides of the river, preventing their accumulation. Compared to traditional manual cleaning, this method is not only more timely but also significantly improves cleaning efficiency.

[0017] 2. By setting up a cleaning component, the second drive unit drives the support frame to descend. The support frame drives multiple sets of cutter parts to slide between two sets of grid plates through multiple sets of uprights and L-shaped frames, thereby effectively scraping off the dirt attached to the side wall of the grid plate, thus avoiding the formation of dirt layer and ensuring that water can flow through the trash rack unimpeded.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] Please see Figure 1-11 This utility model provides an automated debris-blocking device for a river intake gate, including a debris-blocking grid 2 installed behind the river intake gate 1. The debris-blocking grid 2 includes a set of fixed frames 21 and multiple sets of vertically arranged grid plates 22. The multiple sets of grid plates 22 are horizontally and equidistantly fixed to the rear side of the fixed frames 21. A debris-cleaning assembly 3 is installed behind the debris-blocking grid 2. The debris-cleaning assembly 3 includes two sets of support seats 31 and two sets of screen plates 33 symmetrically arranged on the left and right sides of the river. The two sets of support seats 31 are respectively fixed to the banks on the left and right sides of the river. The upper ends of the two sets of screen plates 33 are respectively hinged to the two sets of support seats 31. One side of each of the two sets of support seats 31 is connected to a drive component 34 for driving the screen plate 33 to flip. The inner side of the trash rack 2 is equipped with a cleaning component 4 for cleaning the side wall of the rack plate 22. The cleaning component 4 includes multiple sets of blades 41, which are located between two adjacent rack plates 22. One side of the blades 41 is detachably connected to an L-shaped frame 42. The upper end of the L-shaped frame 42 is fixedly connected to a vertical rod 422. The upper ends of the multiple vertical rods 422 are detachably installed on the support frame 43. One side of the support frame 43 is equipped with a drive component 44 for driving the support frame 43 to rise and fall.

[0033] Specifically, the debris barrier 2 is located behind the river inlet gate 1 and is used to intercept floating objects or debris in the river.

[0034] Specifically, the cleaning component 3 is located behind the trash rack 2 and is used to clean the debris intercepted by the trash rack 2. By setting up the cleaning component 3, when it is necessary to clean debris on one side of the trash rack 2, the drive unit 34 on the left drives the set of screen plates 33 to rotate counterclockwise, and the drive unit 34 on the right drives the set of screen plates 33 to rotate clockwise. Both sets of screen plates 33 rotate together, scooping up the debris on one side of the trash rack 2. After rotating to a suitable angle, the debris is dumped onto both sides of the river (in practical applications, debris storage hoppers can be installed on both sides of the river to facilitate the collection of the scooped debris).

[0035] Specifically, by setting up the cleaning component 4, the dirt attached to the side wall of the grid plate 22 can be effectively removed, preventing the dirt from adhering for a long time and forming a hard layer of dirt that would obstruct the normal flow of water. When cleaning the dirt on the side wall of the grid plate 22, the driving component 44 drives the support frame 43 to descend. The support frame 43 drives multiple sets of cutting tools 41 to slide between the two sets of grid plates 22 through multiple sets of uprights 422 and L-shaped frame 42, thereby scraping off the dirt attached to the side wall of the grid plate 22.

[0036] Furthermore, the screen plate 33 is composed of multiple long screen bars 331 arranged parallel to each other along the width of the river channel. The distance between two adjacent sets of long screen bars 331 is equal to the width of a single long screen bar 331. When the left and right sets of screen plates 33 are parallel to the river channel surface, the free ends of the two sets of screen plates 33 are interlaced. The upper surfaces of the long screen bars 331 located at the front and back sides are fixedly connected to side guard plates 332. The upper ends of the multiple long screen bars 331 are jointly fixedly connected to a feed plate 35.

[0037] Specifically, multiple long screen bars 331 are spaced apart, forming dense filtration gaps that can both intercept debris (such as branches and garbage) and ensure water flow, preventing blockages. When the left and right sets of screen plates 33 are in a horizontal state (parallel to the river surface), the free ends (unhinged ends) of the two sets of screen plates 33 are staggered, forming a continuous interception surface, preventing gaps between the two sets of screen plates 33 from causing debris to fall. Secondly, two sets of side guard plates 332 are fixed to both sides of the screen plate 33, preventing debris from sliding away from the sides of the screen plate 33 during debris removal. In addition, when the screen plate 33 is flipped so that the side of the discharge plate 35 is lower than the side of the free end of the screen plate 33, the debris on the screen plate 33 will slide down to the discharge plate 35 as the screen plate 33 tilts, and finally slide down along the discharge plate 35 to both sides of the river.

[0038] Furthermore, a rotating seat 32 is fixedly connected to the upper side of multiple sets of long screen bars 331. The front and rear ends of the rotating seat 32 are fixedly connected to shafts 321. Both sets of shafts 321 are rotatably connected to the upper inner side of the support seat 31. The driving component 34 includes a first sprocket 341, a first motor 342, and a second sprocket 343. The first sprocket 341 is fixedly sleeved on the outside of one set of shafts 321. The first motor 342 is fixedly installed on one side of the support seat 31. The second sprocket 343 is fixedly sleeved on the outside of the output shaft of the first motor 342. A synchronous chain 344 is sleeved on the outside of the first sprocket 341 and the second sprocket 343. A protective cover is also installed on one side of the support seat 31, which can protect the first motor 342, the first sprocket 341, the second sprocket 343, and the synchronous chain 344.

[0039] Specifically, when it is necessary to clean up the waste, motor 342 operates, and the output shaft of motor 342 drives the outer sprocket 341 to rotate. Under the action of synchronous chain 344, sprocket 343 also rotates synchronously. Sprocket 343 then drives the rotating seat 32 and multiple sets of long screen bars 331 to rotate through shaft 321, thereby realizing the flipping operation of screen plate 33. After the waste is dumped to both sides of the river, controlling the output shaft of motor 342 to operate in the opposite direction will drive screen plate 33 to reset.

[0040] Furthermore, the cutting tool component 41 includes a fixed base 411 and four sets of cutting tools 412. The four sets of cutting tools 412 are detachably installed on the upper and lower surfaces of the fixed base 411 on the left and right sides respectively. The upper and lower surfaces of the fixed base 411 are symmetrically provided with slots 4111. Each set of cutting tools 412 consists of an insert plate 4121 and a scraper 4122. The scraper 4122 and the insert plate 4121 are fixedly connected at an obtuse angle. The insert plate 4121 is movably inserted into the slot 4111 and the two are fixed by bolts. The side of the four sets of scrapers 4122 away from the insert plate 4121 is in contact with the side wall of the grid plate 22.

[0041] Specifically, the blade 412 is detachably fixed to the base 411, facilitating quick disassembly and replacement. Secondly, the scraper 4122 is fixedly connected to the insert plate 4121 at an obtuse angle. This obtuse angle design creates an inclined contact surface between the scraper 4122 and the side wall of the grid plate 22, enhancing the scraping force and improving the efficiency of the scraper 4122 in removing dirt adhering to the side wall of the grid plate 22.

[0042] Furthermore, the front and rear sides of the fixed base 411 are provided with through slots 4112, and the lateral side ends of the L-shaped frame 42 are fixedly connected to a fixing block 421. The fixing block 421 is movably inserted into the through slot 4112 and the two are fixed by bolts.

[0043] Specifically, the fixed base 411 and the L-shaped frame 42 adopt a detachable structure, which facilitates subsequent maintenance and disassembly.

[0044] Furthermore, the support frame 43 includes an upper crossbeam 431 and a lower crossbeam 432. The surface of the upper crossbeam 431 is provided with multiple sets of equidistantly distributed limiting holes 4311, and the surface of the lower crossbeam 432 is provided with multiple sets of equidistantly distributed positioning holes 4321. The upper end of the vertical side of the L-shaped frame 42 is fixedly connected to a vertical rod 422. The upper end of the vertical rod 422 passes through the positioning hole 4321 and the limiting hole 4311 from bottom to top. Two sets of fixing nuts 423 are threaded on the outer side of the vertical rod 422. The two sets of fixing nuts 423 abut against the upper and lower surfaces of the upper crossbeam 431 respectively. The left and right ends of the upper crossbeam 431 and the lower crossbeam 432 are both fixed with side blocks 433.

[0045] Specifically, the upright 422 is fixedly connected to the support frame 43 via a detachable structure, facilitating subsequent disassembly and replacement. When disassembling the upright 422, the upper fixing nut 423 is unscrewed, allowing the upright 422 to slide relative to the upper crossbeam 431. After the top of the upright 422 disengages from the limiting hole 4311, the other set of fixing nuts 423 is also unscrewed, allowing the top of the upright 422 to smoothly disengage from the positioning hole 4321, thus completing the disassembly operation between the upright 422 and the support frame 43.

[0046] Furthermore, the second driving component 44 includes two sets of columns 441, a set of lead screws 443, and a second motor 444. The two sets of columns 441 are fixedly connected to the embankments on the left and right sides of the river channel, respectively. A guide block 4331 is fixedly connected to one side of each of the two sets of side blocks 433. A guide groove 4411 is fixedly connected to the rear side of each of the two sets of columns 441. The two sets of guide blocks 4331 are slidably connected to the inner side of the guide groove 4411 at corresponding positions. Two sets of vertically distributed horizontal plates 442 are fixedly connected between the two sets of columns 441. The lead screw 443 is rotatably connected to the lower... At the center of the upper surface of the horizontal plate 442, the upper end of the lead screw 443 rotates through the upper horizontal plate 442 and is fixedly connected to the output shaft of the second motor 444. The second motor 444 is fixedly installed on the upper surface of the upper horizontal plate 442 by a fixing bracket. The outer side of the lead screw 443 is threaded with a nut seat 445. The left and right sides of the nut seat 445 are fixedly connected with connecting rods 446. The side of the connecting rod 446 near the support frame 43 is fixedly connected with a fixing plate 447. The fixing plate 447 is fixedly connected to the front side of the upper crossbeam 431 and the lower crossbeam 432.

[0047] Specifically, the guide groove 4411 guides and limits the guide block 4331, ensuring that the support frame 43 can only slide vertically along the column 441. When it is necessary to clean the dirt attached to the side wall of the grid plate 22, the control motor 444 operates. The output shaft of the motor 444 drives the lead screw 443 to rotate, thereby causing the nut seat 445 to slide vertically along the outside of the lead screw 443. The nut seat 445, through the connecting rod 446 and the fixing plate 447, drives the support frame 43 to move as a whole, thereby indirectly driving the cutting tool 41 to perform cleaning operations between the two sets of grid plates 22. In the uncleaned state, the nut seat 445 drives the support frame 43 to a high position, so that multiple sets of cutting tools 41 are above the water surface, preventing them from being immersed in water for a long time, thus preventing corrosion and damage to the cutting tools 41. In practical applications, protective covers can also be added to the outside of the lead screw 443 and the motor 444.

[0048] It should be noted that both motor 342 and motor 444 mentioned above are electrically connected to the control terminal. Simultaneously, the control terminal can be used in conjunction with a timer to automatically start motor 342 and motor 444 according to preset time intervals or conditions, thereby automating the operation of the cleaning component 3 and the cleaning component 4. The circuit structure and working principle involved here are existing technologies and will not be elaborated upon further in this article.

[0049] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
