Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to an automatic silt removal device for water conservancy project gates. Background Art

[0002] Gate desilting is an important maintenance task in water conservancy projects. It mainly involves clearing silt and sediment around and inside the gates to ensure the normal operation of the sluice and smooth water flow. At the gates, the water flow speed usually slows down, causing suspended matter to settle and form silt. The accumulation of silt will hinder the water flow and affect water level control and flood discharge capacity. At the same time, the silt will cause corrosion and wear to the mechanical structure of the gate, affecting its service life.

[0003] When existing engineers clean the silt at the gate, the most common method is to open the gate to a certain height so that the silt in the bottom area of ​​the gate is pressed into the downstream of the gate under the impact of the water flow, thereby completing the cleaning of the silt accumulated at the gate. However, the following problems still exist: although this method can quickly clean the silt through water pressure, the silt attached to the surface of the gate cannot be effectively cleaned, and manual dredging tools and high-altitude operations are required to clean the silt attached to the surface of the gate to prevent the gate from being corroded and worn by the silt. This method has great safety hazards and is relatively inefficient. Summary of the invention

[0004] In view of the problem that the existing technology of silting by opening the gate can only effectively clean the silt accumulated under the gate, but cannot clean the silt attached to the surface of the gate, an automatic silt cleaning device for water conservancy project gates is proposed.

[0005] The present application provides an automated silt removal device for water conservancy project gates, the purpose of which is to: by arranging a driving component, when engineering personnel open the gate to remove silt, the mixture of flowing river water and silt drives the rotating rod to rotate, thereby driving the cleaning component to simultaneously clean the silt attached to the gate surface, thereby achieving the goal of cleaning the silt accumulated under the gate while also cleaning the silt attached to the gate surface, without the need for manual intervention, and effectively improving the cleaning efficiency and quality of the gate silt.

[0006] The technical solution of the present invention is: an automatic silt removal device for a water conservancy project gate, comprising a gate plate, and a silt removal unit arranged on the gate plate, wherein the silt removal unit comprises a driving component arranged inside the gate plate and a cleaning component arranged on the surface of the gate plate;

The lifting rod and the rotating rod are both rotatably mounted on the synchronous seat plate, and the transmission gear 1 is meshed with the transmission gear 2.

[0010] Furthermore, the cleaning component includes vertical grooves opened on both sides of the gate plate, ball nuts threadedly arranged on the corresponding reciprocating screws, a receiving rod arranged on the ball nut, a cleaning plate 1 arranged between the two receiving rods, a square plate arranged at the lower end of the cleaning plate, and a cleaning plate 2 arranged at the lower end of the square plate, and the interiors of the cleaning plate 1 and the cleaning plate 2 are both provided with fitting components, and the interiors of the two vertical grooves are both installed with closing components.

[0011] Furthermore, the fitting component includes a plurality of telescopic springs arranged on the inner walls of cleaning plate one and cleaning plate two, and a scraper arranged at one end of the corresponding plurality of telescopic springs. Both of the scrapers are slidably installed inside the corresponding cleaning plate one and cleaning plate two, and one end of the two scrapers is tightly attached to the surface of the gate plate.

[0012] Furthermore, the closing assembly includes a horizontal groove opened on the side wall of the vertical groove, a water baffle plate slidably arranged inside the horizontal groove, a horizontal tooth plate arranged on the side wall of the water baffle plate, a rotating shaft arranged in the mounting groove, and a driving gear arranged on the rotating shaft, the horizontal tooth plate is meshed with the driving gear, and a trigger element is installed between the rotating shaft and the limit plate.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example 1, reference Figure 1-Figure 2 , which is the first embodiment of the present invention, provides an automatic silting device for a water conservancy project gate, comprising a gate plate 1, and a silting unit installed on the gate plate 1, wherein the silting unit comprises a driving component installed inside the gate plate 1 and a cleaning component arranged on the surface of the gate plate 1;

[0033] The driving component includes mounting grooves 2 opened on both sides of the gate plate 1, two mounting plates 3 fixedly installed in the two mounting grooves 2, two sleeves 4 fixedly installed at the lower ends of the two mounting plates 3, two sliding rods 5 slidably installed in the two sleeves 4, limit plates 6 fixedly installed at the upper ends of the two corresponding sliding rods 5, fixed rings 7 fixedly installed at the lower ends of the sliding rods 5, bearings 8 fixedly installed in the fixed rings 7, rotating rods 9 fixedly installed in the corresponding two bearings 8, a plurality of blade plates 10 fixedly installed on the rotating rods 9, a lifting groove opened at the lower end of the gate plate 1, and a linkage rod 11 fixedly installed between the two rotating rods 9;

[0034] A plurality of sliding rods 5 are slidably installed in the corresponding sleeves 4 , three blade plates 10 are fixedly installed on the side walls of the two rotating rods 9 , the linkage rod 11 is located in the lifting slot, and a transmission assembly is installed at one end of the two rotating rods 9 .

[0035] Reference Figure 3 and Figure 4The transmission assembly includes a transmission gear 12 fixedly mounted on one end of the rotating rod 9, a reciprocating screw rod 13 rotatably mounted inside the mounting groove 2, a circular groove provided inside the reciprocating screw rod 13, a lifting rod 14 slidably mounted inside the reciprocating screw rod 13, a transmission gear 2 15 fixedly mounted on the lower end of the lifting rod 14, a synchronous seat plate 16 rotatably mounted between the lifting rod 14 and the rotating rod 9, the lifting rod 14 and the rotating rod 9 are both rotatably mounted on the synchronous seat plate 16, and the transmission gear 12 is meshed with the transmission gear 2 15.

[0036] Specifically, when the engineering staff begins to open the gate to desilt (that is, the staff lifts the gate plate 1 to a lower angle so that a large amount of silt accumulated under the gate plate 1 is pressed into the downstream of the gate plate 1 under the action of the water pressure above, thereby completing the cleaning of the silt under the gate plate 1), the driving component uses the water and silt mixture flowing below as kinetic energy, so that the flowing sewage hits the blade plate 10 below the gate plate 1, thereby driving the rotating rod 9 to rotate. By setting the sliding rod 5 and the lifting rod 14, when the gate plate 1 is in a closed state, the rotating rod 9 is inside the mounting groove 2 of the gate plate 1. When the staff opens the gate to desilt, the gate plate 1 moves upward to open the gate. At the same time, the rotating rod 9 slides downward in the sleeve 4 through the sliding rod 5 under the action of gravity, thereby causing the rotating rod 9 and the blade plate 10 below to move downward synchronously and exceed the inside of the mounting groove 2, so that the sewage flowing below can drive the blade plate 10 to drive the rotating rod 9 to rotate. At the same time, because the transmission gear 12 on the rotating rod 9 is meshed with the transmission gear 2 15, a synchronous seat plate 16 is provided so that when the rotating rod 9 and the transmission gear 1 12 move downward, the transmission gear 2 15 at the lower end of the lifting rod 14 can be driven to move downward synchronously through the synchronous seat plate 16, so that the transmission gear 1 12 and the transmission gear 2 15 are always in a meshing state.

[0037] Two clamping plates are integrally formed on the side wall of the lifting rod 14, and the end face shape of the circular groove opened on the reciprocating screw rod 13 is the same as the end face shape of the lifting rod 14, so that the lifting rod 14 can move freely in the vertical direction, and when the lifting rod 14 itself rotates, it can drive the reciprocating screw rod 13 to move synchronously.

[0038] During use, when the gate 1 is in a closed state, the rotating rod 9 and the blade plate 10 above are in the mounting groove 2. When the staff needs to open the gate to clean the silt accumulated under the gate 1, the staff opens the gate 1 to a certain height, so that the silt accumulated under the gate 1 is washed away by the water pressure above, and the mixture of water and silt (sewage) flows into the downstream of the gate 1 under the action of gravity. At the same time, when the gate plate 1 is rising, the rotating rod 9 slides downward under the action of gravity, so that the rotating rod 9 slides downward in the sleeve 4 through the sliding rod 5, and the rotating rod 9 drives the lifting rod 14 to move downward synchronously through the synchronous seat plate 16, ensuring that the transmission gear 1 12 and the transmission gear 2 15 are always in a meshing state. When the rotating rod 9 drops to the lowest point, the flowing sewage will produce an impact force on the blade plate 10, and then drive the rotating rod 9 to rotate through the blade plate 10. The rotation of the rotating rod 9 drives the transmission gear 1 12 at one end to rotate, and the rotation of the transmission gear 12 drives the lifting rod 14 to rotate through the transmission gear 2 15, thereby driving the reciprocating screw rod 13 above the lifting rod 14 to rotate synchronously.

[0039] Example 2, reference Figure 6-Figure 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cleaning component includes vertical grooves 17 opened on both sides of the gate plate 1, ball nuts 18 respectively threadedly installed on the corresponding reciprocating screws 13, a receiving rod 19 fixedly installed on the ball nut 18, a cleaning plate 20 fixedly installed between the two receiving rods 19, a square plate 21 fixedly installed at the lower end of the cleaning plate 20, a cleaning plate 22 fixedly installed at the lower end of the square plate 21, the cleaning plates 1 20 and 22 are both provided with fitting components, and the two vertical grooves 17 are both installed with closing components.

[0040] Specifically, one end of the receiving rod 19 passes through the vertical groove 17 and is located on the outer side of the gate plate 1. The receiving rod 19 is used to limit the ball nut 18 to prevent the ball nut 18 from rotating with the rotation of the reciprocating screw 13. At the same time, the receiving rod 19 is used to support the cleaning plate 1 20. When the reciprocating screw 13 rotates, the ball nut 18 on the reciprocating screw 13 will reciprocate in the vertical direction, and then drive the cleaning plate 1 20 and the cleaning plate 2 22 to reciprocate synchronously through the receiving rod 19, and reciprocate to clean the sludge attached to the surface of the gate plate 1, thereby realizing the automatic cleaning of the sludge attached to the surface of the gate plate 1 while cleaning the sludge accumulated under the gate plate 1, effectively improving the cleaning efficiency and quality.

[0041] Reference Figure 6 and Figure 7The fitting component includes a plurality of telescopic springs 23 fixedly mounted on the inner walls of the cleaning plate 1 20 and the cleaning plate 2 22, and a scraper 24 fixedly mounted on one end of the corresponding plurality of telescopic springs 23. The two scrapers 24 are slidably mounted inside the corresponding cleaning plate 1 20 and the cleaning plate 2 22. One end of the two scrapers 24 is tightly attached to the surface of the gate plate 1. The length of the square plate 21 is equal to the distance from the bottom end of the vertical groove 17 to the lower end of the gate plate 1. The ends of the two scrapers 24 in contact with the gate plate 1 are both provided with chamfers.

[0042] Specifically, the existing gate plate 1 is usually designed to be arc-shaped, and the arc shape can more effectively withstand water pressure. The pressure exerted by the water flow will be evenly distributed along the surface of the gate plate 1, but in the above process, the cleaning plate 20 reciprocates in the vertical direction. Therefore, the single vertical reciprocating motion will cause the cleaning plate 20 to be unable to effectively clean the entire surface of the arc-shaped gate plate 1. Therefore, by setting a fitting component, multiple telescopic springs 23 always generate outward pressure on the scraper 24, so that no matter where the cleaning plate 20 and the cleaning plate 22 move to the gate plate 1, the telescopic spring 23 can always make one end of the scraper 24 close to the surface of the arc-shaped gate plate 1, so as to effectively clean the silt attached to the surface of the gate plate 1.

[0043] During use, when the reciprocating screw 13 rotates, the ball nut 18 thereon will move downward in the vertical direction, and then drive the cleaning plate 1 20 and the cleaning plate 2 22 to move synchronously through the receiving rod 19. During the movement of the cleaning plate 1 20 and the cleaning plate 22, one end of the scraper 24 slidably installed inside is always in close contact with the surface of the gate plate 1, so that the scraper 24 can effectively clean the silt attached to the surface of the gate plate 1 during the downward movement.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3, reference Figure 1 as well as Figure 4-Figure 5 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the closing component includes a horizontal groove opened on the side wall of the vertical groove 17, a water baffle 25 slidably installed inside the horizontal groove, a horizontal tooth plate 26 fixedly installed on the side wall of the water baffle 25, a rotating shaft 27 rotatably installed in the installation groove 2, a driving gear 28 fixedly installed on the rotating shaft 27, the horizontal tooth plate 26 is meshed with the driving gear 28, and a trigger element is installed between the rotating shaft 27 and the limiting plate 6.

[0046] Specifically, the water retaining plate 25 is used to keep the vertical groove 17 above it in a closed state when the gate plate 1 is in a closed state to ensure the water retaining effect of the gate plate 1. When the gate plate 1 is lifted, the vertical groove 17 will be automatically opened through the closing component to ensure that the receiving rod 19 can reciprocate normally in the vertical direction.

[0047] Reference Figure 8 The trigger element includes a vertical tooth plate 29 fixedly mounted on the side wall of the limiting plate 6, a shaft 30 rotatably mounted in the mounting groove 2, a trigger tooth column 31 fixedly mounted on the shaft 30, a bevel gear 1 32 fixedly mounted on the shaft 30, and a bevel gear 2 33 fixedly mounted on the rotating shaft 27, and the bevel gear 1 32 is meshed with the bevel gear 2 33.

[0048] Specifically, when the gate 1 is opened, the rotating rod 9 and the limit plate 6 move downward relatively under the action of gravity. During the downward movement, the vertical tooth plate 29 on the limit plate 6 drives the trigger tooth column 31 to rotate, and then the water baffle 25 is opened through the trigger element for subsequent use.

[0049] During use, when the gate 1 moves upward to open, the rotating rod 9 and the limit plate 6 drive the sliding rod 5 to slide downward. During the downward sliding process of the limit plate 6, the vertical tooth plate 29 at its upper end moves downward synchronously. During the movement, the trigger tooth column 31 is driven to rotate, and then the shaft 30 is driven to rotate synchronously. The shaft 30 rotates through the bevel gear 1 32 to drive the bevel gear 2 33 to rotate, and then the rotating shaft 27 is driven to rotate. The rotating shaft 27 drives the coaxial driving gear 28 to rotate, and then the water retaining plate 25 is pulled to move in the horizontal direction through the horizontal tooth plate 26, thereby opening the vertical slot 17 to ensure subsequent normal cleaning. Similarly, when the receiving rod 19 rises to the highest position. When the gate 1 moves downward to close, it will drive the trigger tooth column 31 to rotate in the opposite direction, so that the water retaining plate 25 closes the vertical slot 17.

[0050] The remaining structure is the same as that of Example 2.

[0051] Based on Examples 1-3, the working principle of the present invention is as follows: when the gate 1 is in a closed state, the rotating rod 9 and the upper blade plate 10 are in the mounting groove 2. When the staff needs to open the gate to clean the silt accumulated under the gate 1, the staff opens the gate 1 to a certain height, so that the silt accumulated under the gate 1 is washed away by the water pressure from above, and the mixture of water and silt (sewage) flows into the downstream of the gate 1 under the action of gravity.

[0052] When the gate plate 1 moves upward to open, the rotating rod 9 and the limit plate 6 drive the sliding rod 5 to slide downward. During the downward sliding process of the limit plate 6, the vertical tooth plate 29 at its upper end moves downward synchronously. During the movement, the trigger tooth column 31 is driven to rotate, and then the shaft rod 30 is driven to rotate synchronously. The rotation of the shaft rod 30 drives the bevel gear 2 33 to rotate through the bevel gear 1 32, and then drives the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 drives the coaxial driving gear 28 to rotate, and then pulls the water retaining plate 25 in the horizontal direction through the horizontal tooth plate 26, thereby opening the vertical slot 17 to ensure subsequent normal cleaning.

[0053] When the gate plate 1 is rising, the rotating rod 9 slides downward under the action of gravity, so that the rotating rod 9 slides downward in the sleeve 4 through the sliding rod 5, and the rotating rod 9 drives the lifting rod 14 to move downward synchronously through the synchronous seat plate 16, ensuring that the transmission gear 1 12 and the transmission gear 2 15 are always in a meshing state. When the rotating rod 9 drops to the lowest point, the flowing sewage will produce an impact force on the blade plate 10, and then drive the rotating rod 9 to rotate through the blade plate 10. The rotation of the rotating rod 9 drives the transmission gear 1 12 at one end to rotate, and the rotation of the transmission gear 12 drives the lifting rod 14 to rotate through the transmission gear 2 15, thereby driving the reciprocating screw rod 13 above the lifting rod 14 to rotate synchronously.

[0054] When the reciprocating screw 13 rotates, the ball nut 18 thereon will move downward in the vertical direction, and then drive the cleaning plate 1 20 and the cleaning plate 2 22 to move synchronously through the receiving rod 19. During the movement of the cleaning plate 1 20 and the cleaning plate 22, one end of the scraper 24 slidably installed inside is always in close contact with the surface of the gate plate 1, so that the scraper 24 can effectively clean the silt attached to the surface of the gate plate 1 during the downward movement.

[0055] When the sludge is cleared, the receiving rod 19 rises to the initial position, and the staff controls the gate plate 1 to move downward. During the downward movement of the gate plate 1, the rotating rod 9 and the limit plate 6 will move upward relatively with the sliding rod 5 after contacting the bottom of the water, and then enter the installation groove 2 and no longer rotate with the water flow. During the rising process, the vertical tooth plate 29 moves upward, driving the trigger tooth column 31 to rotate in the opposite direction, thereby closing the water retaining plate 25.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
