Description

Technical Field

[0001] This invention relates to the field of water gate technology in water conservancy projects, specifically to a water gate device for water conservancy projects. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, and discharge sediment and floating debris. When selecting a gate type, it is necessary to consider the gate's working nature, installation location, operating conditions, gate span, opening and closing force, and project cost, combined with the gate's characteristics and existing operating experience, and determine the type through technical and economic comparison. Among them, plane gates and arc gates are the most commonly used gate types. Large and medium-sized exposed and submerged working gates mostly use arc gates. Arc gates are especially commonly used for high-head deep-hole working gates. Over a long period of use in water conservancy projects, foreign objects and dirt in the water will adhere to the gate, affecting the normal opening of the gate and affecting its appearance.

[0003] Chinese Patent CN211340688U discloses a sluice gate cleaning device for hydraulic engineering, including a sluice gate side plate. A gate plate is provided on the rear side of the sluice gate side plate, and the gate plate is fixedly connected to the lower surface of the sluice gate side plate. First sliding grooves are formed on the rear sides of both the inner left and inner right walls of the sluice gate side plate, and second sliding grooves are formed on the front sides of both the inner left and inner right walls. A water suction device is provided at the inner bottom of the sluice gate side plate. This sluice gate cleaning device achieves primary cleaning of the sluice gate through the cooperation of cleaning nozzles and cleaning wheels, improving the cleaning speed and efficiency, reducing the adhesion of dirt on the sluice gate surface, and making the cleaning more thorough. Secondary cleaning of the sluice gate is achieved by scraping the surface with a scraper, further improving the cleaning efficiency and achieving a more thorough cleaning effect. However, this application does not disclose the following technical effects:

[0004] 1. Unable to automatically approach the gate plate and clean its side wall surface without power;

[0005] 2. Existing gates have poor safety during use, especially during the process of lowering and closing the gate. They are prone to contact with suspended objects, large aquatic animals, or underwater workers, causing injury and safety accidents. They can also easily hinder the complete closure of the gate plate, which is not conducive to the gate closing. Summary of the Invention

[0006] To address the problems existing in current technology, a sluice gate device for hydraulic engineering is provided. Through the coordination of a linkage mechanism, a horizontal support, and a movable support, the cleaning component automatically moves closer to the side wall of the gate plate during its ascent. The cleaning component cleans the side wall of the gate plate during this ascent. A drive wheel on the drive shaft rotates along the rising gate plate, and a synchronous belt mechanism on the drive shaft drives the cleaning rollers to rotate. This allows the cleaning rollers to rotate automatically during the gate plate's ascent, driving the first cleaning brushes to clean the dirt on the side wall of the gate plate. A reverse rotation mechanism between the two cleaning rollers causes them to rotate in opposite directions, which in turn drives the corresponding first cleaning brushes to rotate in opposite directions, thereby increasing the cleaning effect and making the dirt on the side wall of the gate plate more thorough. During the descent of the gate plate, the cleaning component moves away from the side wall of the gate plate, moving horizontally. When the gate plate closes, it prevents suspended solids, large aquatic animals, or personnel working in the water from approaching the gate plate, providing safety protection and ensuring complete closure of the gate plate.

[0007] To address the problems of existing technologies, this invention provides a sluice gate device for water conservancy projects, comprising a frame, a gate plate disposed within the frame, and a lifting device disposed at the top of the frame for raising and lowering the gate plate. Vertically arranged limiting rods are provided on both sides of the upper end of the gate plate. A shaft bearing is provided on the frame for each limiting rod to pass through. Horizontal supports corresponding to each limiting rod are provided on both sides of the frame. Movable supports that can move closer to or further away from the side wall of the gate plate are provided on the horizontal supports. A linkage mechanism is provided between the limiting rods and the movable supports to drive the movable supports to translate. A cleaning assembly is provided between symmetrically arranged movable supports. The cleaning assembly includes at least two vertically parallel cleaning rollers. A first cleaning brush is provided on the outside of the cleaning rollers to contact the outer wall of the gate plate. The cleaning assembly also includes a drive shaft with a drive wheel that can slide in contact with the outer wall of the gate plate. A synchronous belt mechanism is provided at one end of the drive shaft to drive one of the two cleaning rollers to rotate. A reversing rotation mechanism is provided between the two cleaning rollers to cause them to rotate in opposite directions.

[0008] Preferably, the movable support is vertically positioned below the horizontal support, with a slider at the top and a horizontally positioned slide rail at the bottom. The slider is slidably positioned within the slide rail, and a movable plate passing through the slide rail and the horizontal support is located at the top of the slider. One end of the linkage mechanism is connected to the top of the movable plate via a transmission mechanism. Both the slide rail and the horizontal support have movable through holes for the movable plate to move.

[0009] Preferably, the linkage mechanism includes a telescopic rod, which consists of a sleeve rod and an inner rod. One end of the sleeve rod is hinged to the upper end of the limiting light rod, and the inner rod is telescopically inserted into the sleeve rod. One end of the inner rod is hinged to the top of the moving plate.

[0010] Preferably, the movable support includes a C-shaped support and a movable frame. The C-shaped support is vertically positioned directly below the horizontal support, and its top is connected to the slider. The movable frame is vertically positioned inside the movable support and can move horizontally towards the gate plate. The upper and lower ends of the movable frame are respectively provided with slide bars. The upper and lower ends of the C-shaped support are respectively provided with strip grooves for each slide bar to move horizontally. The two ends of the drive shaft and the cleaning roller shaft are respectively axially connected to the side wall of the corresponding movable frame. The C-shaped support is provided with a buffer rod that is elastically connected to the movable frame.

[0011] Preferably, the buffer rod includes a buffer rod and a spring. The buffer rod is horizontally positioned on the side of the movable frame away from the gate plate. One end of the buffer rod extends outward through one side of the C-shaped bracket. The C-shaped bracket has a first movable through hole for the buffer rod to pass through. The spring is sleeved on the outside of the buffer rod and located between the movable frame and the C-shaped bracket. An anti-detachment disc is provided on the outside of the end of the buffer rod away from the C-shaped bracket. A vertically positioned vertical plate is provided at the bottom of the end of the transverse bracket away from the frame. One end of the buffer rod extends outward through the vertical plate. A second movable through hole is provided on the vertical plate for the buffer rod to pass through.

[0012] Preferably, the reverse rotation mechanism includes a first gear, a second gear, a third gear, and a fourth gear. The first gear and the second gear are coaxially arranged at one end of the two cleaning roller shafts, with the first gear and the second gear corresponding vertically. The third gear and the fourth gear are located between the first gear and the second gear, and the third gear and the fourth gear are rotatably arranged on the side wall of the movable frame. The first gear and the third gear are meshed, the third gear and the fourth gear are meshed, and the fourth gear and the second gear are meshed.

[0013] Preferably, the synchronous belt mechanism includes a driving pulley and a driven pulley. The driving pulley is coaxially disposed at one end of the drive shaft, and the driven pulley is coaxially disposed at one end of one of the two cleaning roller shafts. The driven pulley is located directly above the driving pulley, and the driven pulley is connected to the driving pulley via a synchronous belt.

[0014] Preferably, the drive wheel has several protrusions that are evenly spaced along the circumference of the drive wheel.

[0015] Preferably, a cover is provided above the drive shaft to cover the upper end of each drive wheel, and the two sides of the cover are fixedly connected to the inner sidewall of the corresponding movable frame through connecting brackets.

[0016] Preferably, a second cleaning brush is provided laterally at the bottom of the cover, which can contact the circumferential surface of the drive wheel.

[0017] The advantages of this application compared to the prior art are:

[0018] 1. This application uses the linkage mechanism, the horizontal support, and the movable support to automatically drive the cleaning component to approach the side wall of the gate plate during the upward process, and cleans the side wall of the gate plate during the upward process through the cleaning component.

[0019] 2. In this application, the drive wheel on the drive shaft rotates along the gate plate during the upward process, and the synchronous belt mechanism on the drive shaft drives the cleaning roller to rotate, so that the cleaning roller can automatically rotate during the upward process of the gate plate, and the first cleaning brush is driven by the rotation to clean the dirt on the side surface of the gate plate.

[0020] 3. This application uses a reverse rotation mechanism between two cleaning rollers to make the two cleaning rollers rotate in opposite directions. The two reverse rotating cleaning rollers drive the corresponding first cleaning brush to rotate in opposite directions, thereby increasing the cleaning effect and making the stains on the side wall of the gate plate more thoroughly cleaned.

[0021] 4. When the gate plate moves downward, the moving frame moves away from the gate plate, and the cleaning roller does not rotate. At this time, the cleaning roller moves outward, which can have an outward pushing effect. This prevents suspended objects, large animals, or underwater workers from approaching the gate plate during the closing process, ensuring the safe closure of the gate plate. The cleaning component not only cleans the dirt on the side wall of the gate plate when it is open, but also cleans objects in the water around the gate plate when it is closed.

Detailed Implementation

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1 to 10As shown, a sluice gate device for a water conservancy project includes a frame 1, a gate plate 2 disposed within the frame 1, and a lifting device 3 disposed on the top of the frame 1 for raising and lowering the gate plate 2. Vertically arranged limiting rods 21 are respectively provided on both sides of the upper end of the gate plate 2. A shaft bearing for each limiting rod 21 to pass through is provided on the frame 1. Horizontal supports 4 are provided on both sides of the frame 1, corresponding one-to-one with each limiting rod 21. Moving supports 41 that can move closer to or further away from the side wall of the gate plate 2 are provided on the horizontal supports 4. A linkage mechanism 42 is provided between the limiting rods 21 and the moving supports 41, enabling the moving supports 41 to translate. Cleaning components 5 are provided between the two symmetrical moving supports 41 in the moving support 41. The cleaning components 5 include at least two vertically parallel cleaning rollers 51. The outer side of the cleaning rollers 51 is provided with a first cleaning brush 511 that can contact the outer wall of the gate plate 2. The cleaning components 5 also include a drive shaft 52. The drive shaft 52 is provided with a drive wheel 521 that can roll on the outer wall of the gate plate 2. One end of the drive shaft 52 is provided with a synchronous belt mechanism 53 for driving one of the two cleaning rollers 51 to rotate. A reverse rotation mechanism 54 is provided between the two cleaning rollers 51 to make the two cleaning rollers 51 rotate in opposite directions.

[0035] When the gate plate 2 is lifted by the lifting device 3, the gate plate 2 drives the limit rod 21 to move upward simultaneously. When the limit rod 21 moves upward, the limit rod 21 drives the moving bracket 41 on the transverse bracket 4 to move towards the gate through the linkage mechanism 42, and at the same time drives the corresponding drive wheel 521 to slide into contact with the outer wall of the gate plate 2. When the gate plate 2 moves upward, the drive wheel 521 can rotate with the drive shaft 52 by friction with the outer wall of the gate plate 2. The drive shaft 52 drives one of the two cleaning roller shafts 51 to rotate through the synchronous belt mechanism 53, and drives the other cleaning roller shaft 51 to rotate in the opposite direction through the reverse rotation mechanism 54. The two cleaning roller shafts 51 clean the dirt on the outer wall of the gate plate 2 by rotating in the opposite direction and cooperating with the corresponding first cleaning brush 511, so that the dirt on the gate plate 2 is automatically cleaned in the lifting state, improving the use of the sluice gate.

[0036] When the gate plate 2 descends via the lifting device 3, the gate plate 2 drives the limit rod 21 to move downwards simultaneously. When the limit rod 21 moves downwards, it drives the movable bracket 41 on the transverse support 4 away from the gate plate 2 via the linkage mechanism 42, and simultaneously drives the corresponding drive wheel 521 and cleaning roller 51 away from the gate plate 2. After the drive wheel 521 is completely disengaged from the gate plate 2, the movable bracket 41 continues to drive the cleaning roller 51 to move outwards. At this time, the cleaning roller 51 will not rotate. The outward movement of the cleaning roller 51 can have an outward pushing effect, so that the gate plate 2 can prevent personnel and other objects in the water from approaching during the closing process, ensuring the safe closing of the gate plate 2.

[0037] Through the cooperation of the linkage mechanism 42, the horizontal support 4, and the movable support 41, the gate plate 2 automatically drives the cleaning component 5 to approach the side wall of the gate plate 2 during the rising process, and the cleaning component 5 cleans the side wall of the gate plate 2 during the rising process.

[0038] The drive wheel 521 on the drive shaft 52 rotates along the gate plate 2 during the upward process, and the synchronous belt mechanism 53 on the drive shaft 52 drives the cleaning roller shaft 51 to rotate, so that the cleaning roller shaft 51 can rotate automatically during the upward process of the gate plate 2, and the first cleaning brush 511 is driven by the rotation to clean the dirt on the side wall of the gate plate 2.

[0039] The two cleaning rollers 51 are rotated in opposite directions by a reverse rotation mechanism 54 between them. The two reverse rotating cleaning rollers 51 drive the corresponding first cleaning brush 511 to rotate in opposite directions, thereby increasing the cleaning effect and making the stains on the side wall of the gate plate 2 more thoroughly cleaned.

[0040] See Figure 1 , Figure 6 and Figure 7 As shown, the movable support 41 is vertically positioned below the horizontal support 4. A slider 411 is provided on the top of the movable support 41, and a horizontally positioned slide rail 43 is provided on the top of the horizontal support 4. The slider 411 is slidably positioned within the slide rail 43. A movable plate 4111, which passes through the slide rail 43 and the horizontal support 4, is provided on the top of the slider 4111. The linkage mechanism 42 is connected to the top of the movable plate 4111. Both the slide rail 43 and the horizontal support 4 are provided with movable through holes for the movable plate 4111 to move.

[0041] When the movable support 41 moves, the slider 411 moves parallel to the slide rail 43, so that the movable support 41 can move smoothly on the transverse support 4.

[0042] See Figure 1 , Figure 4 and Figure 5As shown, the linkage mechanism 42 includes a telescopic rod 421, which is composed of a sleeve rod 4211 and an inner rod 4212. One end of the sleeve rod 4211 is hinged to the upper end of the limiting light rod 21. The inner rod 4212 is telescopically inserted into the sleeve rod 4211, and one end of the inner rod 4212 is hinged to the top of the moving plate 4111.

[0043] When the limiting light rod 21 moves downward and one end of the inner rod 4212 is inserted to the deepest point of the sleeve rod 4211, the limiting light rod 21 will continue to move downward. Due to the contact between the inner rod 4212 and the sleeve rod 4211, the inner rod 4212 drives the moving plate 4111 to move away from the gate plate 2 along the horizontal direction of the transverse support 4, and drives the cleaning roller 51 and the drive shaft 52 to move away from the gate plate 2 at the same time, which can push objects close to the gate plate 2 outward.

[0044] When the limiting light rod 21 moves upward, the inner rod 4212 extends along the sleeve rod 4211, causing the sleeve rod 4211 and the inner rod 4212 to flip towards the axis of the limiting light rod 21. During the flipping process, the moving plate 4111 moves towards the gate plate 2.

[0045] See Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the movable support 41 includes a chamfered support 412 and a movable frame 413. The chamfered support 412 is vertically arranged, and its top is connected to the slider 411. The movable frame 413 is vertically arranged inside the chamfered support 412 and can be translated towards the gate plate 2. The upper and lower ends of the movable frame 413 are respectively provided with slide bars 4121. The upper and lower ends of the interior of the chamfered support 412 are respectively provided with strip grooves 4131 for each slide bar 4121 to translate. The two ends of the drive shaft 52 and the cleaning roller shaft 51 are respectively axially connected to the side wall of the corresponding movable frame 413. The chamfered support 412 is provided with a buffer rod 4122 that is elastically connected to the movable frame 413.

[0046] When the drive wheel 521 and the first cleaning brush 511 in the cleaning assembly 5 come into contact with the gate, the buffer rod 4122 enables the moving frame 413 to have a buffering force, so that the drive wheel 521 and the first cleaning brush 511 have a buffering force when they come into contact with the side wall of the gate plate 2, thus avoiding overpressure on the drive wheel 521 and the first cleaning brush 511.

[0047] See Figure 1 , Figure 4 and Figure 5As shown, the buffer rod 4122 includes a buffer rod 41223 and a spring 41224. The buffer rod 41223 is horizontally arranged on the side of the movable frame 413 away from the gate plate 2. One end of the buffer rod 41223 extends outward through one side of the U-shaped bracket 412. The U-shaped bracket 412 is provided with a first movable through hole for the buffer rod 41223 to pass through. The spring 41224 is sleeved on the outside of the buffer rod 41223 and is located between the movable frame 413 and the U-shaped bracket 412. An anti-detachment disc 41225 is provided on the outside of the end of the buffer rod 41223 away from the U-shaped bracket 412. A vertical plate 41226 is provided at the bottom of the end of the transverse bracket 4 away from the frame 1. One end of the buffer rod 41223 extends outward through the vertical plate 41226. The vertical plate 41226 is provided with a second movable through hole for the buffer rod 41223 to pass through.

[0048] When the first cleaning brush 511 and drive wheel 521 on the moving frame 413 contact the side wall of the gate plate 2, the moving frame 413 will translate towards the inside of the U-shaped bracket 412. The buffer rod 41223 will move along the first moving through hole on the U-shaped bracket 412, causing the two ends of the spring 41224 to abut against the inner side wall of the U-shaped bracket 412 and one side of the moving frame 413, respectively. This allows the first cleaning brush 511 on the moving frame 413 to contact the drive wheel... 521 can always slide in contact with the side wall of the gate plate 2, and the first cleaning brush 511 and the drive wheel 521 have a buffering force. The anti-detachment disc 41225 provided on the buffer light rod 41223 can prevent the moving frame 413 from falling off the U-shaped bracket 412 and is used to limit the moving frame 413. The second moving through hole on the vertical plate 41226 cooperates with the buffer light rod 41223 to make the U-shaped bracket 412 more stable when moving.

[0049] See Figure 2 and Figure 9 As shown, the reverse rotation mechanism 54 includes a first gear 541, a second gear 542, a third gear 543, and a fourth gear 544. The first gear 541 and the second gear 542 are coaxially arranged at one end of the two cleaning roller shafts 51, with the first gear 541 and the second gear 542 corresponding vertically. The third gear 543 and the fourth gear 544 are located between the first gear 541 and the second gear 542. The third gear 543 and the fourth gear 544 are rotatably mounted on the side wall of the movable frame 413. The first gear 541 and the third gear 543 are meshed, the third gear 543 and the fourth gear 544 are meshed, and the fourth gear 544 and the second gear 542 are meshed.

[0050] When one of the two cleaning rollers 51 rotates, it drives the first gear 541 to rotate clockwise. The first gear 541 drives the third gear 543 to rotate counterclockwise. The third gear 543 drives the fourth gear 544 to rotate clockwise. The fourth gear 544 drives the second gear 542 to rotate counterclockwise, causing the two cleaning rollers 51 to rotate in opposite directions.

[0051] See Figure 2 and Figure 9 As shown, the synchronous belt mechanism 53 includes a driving wheel 531 and a driven wheel 532. The driving wheel 531 is coaxially disposed at one end of the drive shaft 52, and the driven wheel 532 is coaxially disposed at one end of one of the two cleaning roller shafts 51. The driven wheel 532 is located directly above the driving wheel 531, and the driven wheel 532 is connected to the driving wheel 531 through the synchronous belt 533.

[0052] When the drive shaft 52 rotates, the drive shaft 52 drives the drive wheel 531 to rotate. The drive wheel 531 drives the driven wheel 532 to rotate through the synchronous belt 533. The driven wheel 532 drives the corresponding cleaning roller shaft 51 to rotate, so that the drive shaft 52 can start the cleaning roller shaft 51 to rotate during the rotation process.

[0053] See Figure 10 As shown, the drive wheel 521 has several protrusions 5211 that are evenly distributed along the circumference of the drive wheel 521 on its outer side.

[0054] When the drive wheel 521 moves along the outer wall of the gate plate 2, the protrusion 5211 provided on the drive wheel 521 can increase the contact area and friction of the drive wheel 521, so that the drive wheel 521 can move more smoothly along the outer wall of the gate plate 2.

[0055] See Figure 6 , Figure 8 and Figure 10 As shown, a cover 522 is provided above the drive shaft 52 to cover the upper end of each drive wheel 521. The two sides of the cover 522 are fixedly connected to the inner sidewall of the corresponding moving frame 413 through connecting brackets.

[0056] When the cleaning roller 51 drives the first cleaning brush 511 to clean the outer wall of the gate plate 2, the cleaned dirt will fall from top to bottom. The cover 522 can block the falling dirt and prevent it from affecting the rotation of the drive wheel 521.

[0057] See Figure 10 As shown, a second cleaning brush 5221 is horizontally arranged at the bottom of the cover 522, which can contact the circumferential surface of the drive wheel 521.

[0058] When the drive wheel 521 moves along the outer wall of the gate plate 2, dirt will adhere to the outside of the drive wheel 521. The second cleaning brush 5221 can clean the outside of the drive wheel 521 during the movement, so that the drive wheel 521 remains clean during the movement and avoids excessive dirt on the drive wheel 521 from affecting the rotation of the drive wheel 521.

[0059] Based on the technical solutions disclosed in the above embodiments, the working principle of the sluice gate device in this water conservancy project is as follows:

[0060] This application utilizes the coordination of the linkage mechanism 42, the transverse support 4, and the movable support 41 to automatically drive the cleaning component 5 close to the side wall of the gate plate 2 during its ascent. The cleaning component 5 cleans the side wall of the gate plate 2 during the ascent. The drive wheel 521 on the drive shaft 52 rotates along the gate plate 2 during the ascent, and the synchronous belt mechanism 53 on the drive shaft 52 drives the cleaning roller 51 to rotate. This allows the cleaning roller 51 to rotate automatically during the ascent of the gate plate 2, and the rotation drives the first cleaning brush 511 to clean the side wall of the gate plate 2. To clean the stains, a reverse rotation mechanism 54 is set between the two cleaning rollers 51 to make the two cleaning rollers 51 rotate in opposite directions. The two reverse rotating cleaning rollers 51 drive the corresponding first cleaning brush to rotate in opposite directions, thereby increasing the cleaning effect and making the stains on the side wall of the gate plate 2 more thoroughly cleaned. During the descent of the gate plate, the two cleaning rollers 51 and the drive shaft 52 move away from the gate plate 2. The cleaning rollers 51 and the drive shaft 52 can prevent other objects from moving toward the gate plate 2, especially preventing underwater workers and animals from approaching the gate plate 2, so that the gate plate 2 can be safely lowered and closed.

[0061] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
