Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and in particular to a water conservancy irrigation gate device and a use method thereof. Background Art

[0002] In the process of agricultural irrigation, sluice gates are key facilities for controlling water flow. However, the existing technology still has some shortcomings in the use of sluice gates:

[0003] 1. When using a gate to control water flow, the silt and sand carried in the water tend to accumulate at the bottom of the gate. These deposits will affect the sealing of the gate when it is closed, resulting in a poor effect of the gate intercepting the water flow. At the same time, too much mud and stone in the water flow may also cause blockage of the downstream canal, thus affecting the irrigation effect;

[0004] 2. When the gates are opened to release water, the water will carry garbage into the farmland canals. The garbage will accumulate in the canals, which is not only difficult to clean up, but also easy to cause water blockage, which has an adverse effect on irrigation.

[0005] In view of the above problems, the present invention document proposes a water conservancy irrigation gate device and a method of using the same. Summary of the invention

[0025] S4. When the rotating shaft rotates, it also drives the stirring blade to stir the silt in the collection tank to mix it with water; the water pump then pumps the mixture into the silt tank, and this process also uses suction to remove the residue in the triangular groove; the silt is rich in organic matter and inorganic elements and can be used as a soil conditioner;

[0026] S5. When the gate is opened, the flow-gathering plate drives the guide rod and the inclined scraper to move toward the filter plate to prevent silt and sand from falling into the triangular groove; when the gate is closed, the triangular bar not only scrapes off the debris on the filter plate, but also cooperates with the inclined scraper to remove the garbage on the triangular bar to prevent it from entering the triangular groove.

The triangular bars can prevent the sludge accumulated in the triangular groove from affecting the closure of the gate, and can also prevent the filter plate from being blocked;

[0029] In the present invention, the baffle plates are all slidably penetrated by a same guide rod, a same flow-gathering plate is fixed to one end of the plurality of guide rods away from the frame, and a same inclined scraper is fixed to the other end of the plurality of guide rods; when the gate is opened on the top plate and the gate, the flow-gathering plate drives the guide rod and the inclined scraper to move toward the filter plate under the push of the water flow until the inclined scraper is against the filter plate, thereby preventing mud and silt from falling into the triangular groove; when the gate is moved downward, the triangular bar can not only scrape off the debris and garbage on one side of the filter plate, but the cooperation between the triangular bar and the inclined scraper can also scrape off the debris and garbage scraped off by the triangular bar, thereby preventing the garbage on the triangular bar from entering the triangular groove.

[0030] In the present invention, in the process of the up and down movement of the gate, it is possible to prevent excessive sediment from entering the collecting trough, and the sediment and sludge in the triangular groove and the collecting trough can be extracted and discharged, thereby ensuring the sealing between the gate and the frame.

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] Example 1: Reference Figure 1-Figure 5 The gate device is used in the field of water conservancy projects. The device includes a frame 1 installed in a water channel. A gate 3 is slidably connected inside the frame 1 to control the opening and closing of the water channel. A filter plate 4 is fixed to the inner wall of the bottom of the frame 1. The function of the filter plate 4 is to filter debris and garbage in the water flow to prevent it from entering the area behind the gate 3. The top of the filter plate 4 slides and extends into the gate 3 to ensure that the water flows through the filter plate 4 before flowing through the gate 3.

[0045] Reference Figure 5 and Figure 6 Two triangular grooves 11 are provided on the inner wall of the bottom of the frame 1. The function of the two triangular grooves 11 is to collect the silt and mud in the water flow. A collecting groove 12 is also provided in the frame 1. It is located below the triangular groove 11 and is used to collect the silt and mud falling from the triangular groove 11. A plurality of connecting holes 13 are provided on the side where the two triangular grooves 11 are close to each other. These connecting holes 13 are connected to the collecting groove 12 to ensure that the silt and mud can smoothly enter the collecting groove 12.

[0046] Reference Figure 1-Figure 3 and Figure 5-Figure 7In order to remove the silt and mud, the device also includes a dredging structure. The dredging structure includes a rotating shaft 14 rotating in the collection tank 12, and a plurality of stirring blades 18 are fixedly sleeved on the outer wall of the rotating shaft 14. When the rotating shaft 14 rotates, the stirring blades 18 will rotate accordingly to lift the silt and mud deposited in the collection tank 12. On one side of the frame 1, two sprocket wheels 15 are rotatably connected to the rotating shaft, and the two sprocket wheels 15 are arranged up and down. One end of the rotating shaft 14 rotates and extends to one side of the frame 1, and is fixedly connected to the rotating shaft of the sprocket wheel 15 located below. When the sprocket wheel 15 rotates, it will drive the rotating shaft 14 to rotate together. In order to protect the rotating shaft 14 and the sprocket wheel 15, a protective box 17 is also fixed to one side of the frame 1.

[0047] Reference Figure 1 and Figure 3 In addition, a water pump 19 is fixed on the side of the frame 1 away from the rotating shaft 14. A liquid inlet pipe 20 is fixed to the liquid inlet end of the water pump 19, and one end of the liquid inlet pipe 20 is connected to the collecting tank 12. A liquid discharge pipe 21 is fixed to the liquid outlet end of the water pump 19, and one end of the liquid discharge pipe 21 extends to the sludge tank 41 of the farmland.

[0048] Specifically, when the water pump 19 is working, it will pump the mixed liquid containing sediment and silt in the collecting tank 12 into the silt tank 41 through the drainage pipe 21. These sediments and silt contain rich organic matter and inorganic elements, which can be used as soil conditioners for fertilizing farmland.

[0049] Reference Figure 5-Figure 8 In order to prevent sediment and silt from entering the collection tank 12 when the gate 3 is opened, the device also includes a blocking structure. This blocking structure includes a plurality of threaded rods 31 rotating on the top inner wall of the collection tank 12. Two blocking plates 33 are slidably connected to the top inner wall of the collection tank 12, and the two blocking plates 33 are respectively located on both sides of the threaded rods 31. The outer walls of the plurality of threaded rods 31 are threadedly sleeved with nut blocks 32, and the outer walls of the nut blocks 32 are rotatably connected to two connecting rods 34. The top ends of the plurality of connecting rods 34 located on the same side are rotatably connected to the adjacent blocking plates 33. When the nut block 32 is raised or lowered, the blocking plate 33 is driven to move through the connecting rod 34, thereby achieving the blocking and unblocking of the connecting hole 13.

[0050] Reference Figure 8In order to realize the lifting and lowering of the nut block 32, a plurality of transverse plates 29 are fixed in the collecting tank 12, and a gearbox 30 is fixedly passed through the transverse plates 29. The output shaft of the gearbox 30 is fixedly connected to the bottom end of the corresponding threaded rod 31. In order to slow down the rotation speed of the threaded rod 31, a plurality of box bodies 25 are rotatably sleeved on the outer wall of the rotating shaft 14, and the box bodies 25 are located below the gearbox 30. Fixed rods 24 are fixed on both sides of the box bodies 25, and one end of the fixed rod 24 away from the box body 25 is fixedly connected to the inner wall of one side of the collecting tank 12. A driving shaft 26 is rotatably connected to the top of the box body 25, and the top end of the driving shaft 26 is fixedly connected to the input shaft of the gearbox 30. When the rotating shaft 14 rotates, the gearbox 30 is driven to work through the driving shaft 26, thereby driving the threaded rod 31 to rotate. In order to further enhance the speed reduction effect, the bottom end of the driving shaft 26 rotates and extends into the box body 25 and is fixed with a bevel gear 27 , one side of the bevel gear 27 is meshed with a bevel gear ring 28 , and the bevel gear ring 28 is fixedly sleeved on the outer wall of the fixing rod 24 .

[0051] Reference Figure 1-Figure 4 In order to control the opening and closing of the gate 3 and drive the desilting structure and the blocking structure to work at the same time, a driving structure is set at the top of the frame 1. The driving structure includes a driving motor 6, which is firmly fixed to the top of the frame 1. The output shaft of the driving motor 6 is fixedly connected to a lead screw 5 through a coupling, and the driving motor 6 can drive the lead screw 5 to rotate. The bottom end of the lead screw 5 extends to the inside of the frame 1 by rotating, and is rotatably connected with the top of the filter plate 4. On the outer wall of the lead screw 5, a top plate 2 is provided on the threaded sleeve, and the top plate 2 can slide inside the frame 1. The top of the top plate 2 is fixedly connected to the top of the gate 3, so when the lead screw 5 rotates, the top plate 2 will move up and down along the thread of the lead screw 5, thereby driving the gate 3 to rise and fall. This design makes it possible to accurately control the opening and closing of the gate 3 by controlling the rotation direction and speed of the driving motor 6.

[0052] Reference Figure 3 , Figure 4 and Figure 7 A rectangular groove 22 is provided on one side of the frame 1 near the protection box 17, and a connecting rod 23 is slidably connected in the rectangular groove 22. One end of the connecting rod 23 is fixedly connected to a link of a chain 16, and the other end is fixedly connected to one side of the top plate 2. Therefore, when the top plate 2 is raised or lowered, it drives the chain 16 to run through the connecting rod 23. The operation of the chain 16 further drives the rotating shaft 14 to rotate, thereby providing the required power for the dredging structure and the blocking structure.

[0053] Reference Figure 5 and Figure 6Two triangular bars 10 are fixed on both sides of the bottom of the gate 3. The two triangular bars 10 match the triangular grooves 11 at the bottom of the frame 1. When the gate 3 is closed, the triangular bars 10 will enter the triangular grooves 11 and squeeze the sand, silt and other impurities in the triangular grooves 11 into the collection grooves 12, or squeeze them to the side of the triangular grooves 11 away from the filter plate 4. At the same time, the two triangular bars 10 are closely attached to the two sides of the filter plate 4 on the side close to each other. During the lifting and lowering process of the gate 3, the triangular bars 10 can also scrape off the debris, garbage and the like filtered from the outer wall of the filter plate 4 to keep the filter plate 4 clean.

[0054] Reference Figure 5 In addition, a plurality of air holes 9 are designed in the top plate 2, and the bottom ends of these air holes 9 extend into the gate 3. When the gate 3 is closed, it can still maintain a certain air permeability, avoiding problems such as water quality deterioration or death of aquatic organisms caused by long-term closure.

[0055] Reference Figure 4 Two slide grooves 8 are provided on both sides of the gate 3, and the four slide grooves 8 are designed to accommodate the L-shaped water retaining strips 7. One end of the L-shaped water retaining strip 7 is slidably connected in the slide groove 8, and the other end is fixed on the inner wall of the frame 1, and the fixed position of the L-shaped water retaining strip 7 is adjacent to the gate 3. When the gate 3 is fully closed, the presence of the L-shaped water retaining strip 7 can greatly increase the sealing between the gate 3 and the frame 1, and effectively prevent water from seeping out of the gap between the gate 3 and the frame 1.

[0056] In summary, the water conservancy irrigation gate device of this embodiment drives the lead screw 5 to rotate through the driving motor 6, thereby controlling the lifting and lowering of the top plate 2 and the gate 3, and realizing the opening and closing of the gate 3. At the same time, the top plate 2 also drives the rotating shaft 14 to rotate through the cooperation of the connecting rod 23 and the chain 16, providing power for the silt removal structure and the blocking structure. The triangular bar 10 at the bottom of the gate 3 can effectively remove impurities such as silt and mud in the triangular groove 11, and keep the filter plate 4 clean. The air vents 9 in the top plate 2 can ensure the air permeability of the gate 3 when it is closed.

[0057] Example 2: Reference Figure 9-11 , based on the improvement of Example 1: a plurality of fixed columns 35 are fixed on the side of the frame 1 close to the water flow, and these fixed columns 35 jointly support a baffle 36. A guide rod 38 is slidably penetrated in the baffle 36, and the other end of the guide rod 38 is connected to a flow collecting plate 39. The flow collecting plate 39 is designed to move toward the direction of the frame 1 under the impact of the water flow. A sloped scraper 37 is also fixed on the end of the guide rod 38 close to the frame 1, and the sloped scraper 37 can slide on the bottom inner wall of the frame 1.

[0058] Reference Fig.11The design of the inclined scraper 37 is very clever. One side of it is provided with an inclined surface 40. This inclined surface 40 can cooperate with the triangular strip 10 (the triangular strip 10 is an existing structure in the device, which is used to further increase the sealing performance) to remove the debris and garbage that may be attached to the triangular strip 10. In addition, the inclined scraper 37 is also combined with the design of the filter plate 4. When the focusing plate 39 moves toward the filter plate 4 under the impetus of the water flow, the inclined scraper 37 will also move with it and finally abut against the filter plate 4. In this way, it can effectively prevent debris such as mud and silt from falling into the triangular groove 11, ensuring the smooth operation of the gate device.

[0059] More specifically, when the top plate 2 and the gate 3 are opened, the flow collecting plate 39 will be pushed by the water flow to drive the guide rod 38 and the inclined scraper 37 to move toward the filter plate 4. In this process, the inclined scraper 37 will gradually stick to the filter plate 4, forming an effective barrier to prevent debris from falling into the triangular groove 11. When the gate 3 moves down and closes, the triangular strip 10 will not only scrape off the debris and garbage on one side of the filter plate 4, but its inclined surface will also cooperate with the inclined surface 40 of the inclined scraper 37 to drive the inclined scraper 37 to move away from the filter plate 4. In this process, the inclined scraper 37 will further remove the debris and garbage scraped off by the triangular strip 10 to ensure that the garbage on the triangular strip 10 will not enter the triangular groove 11.

[0060] Through such a design, the water conservancy irrigation gate device of this embodiment not only improves the sealing between the gate and the frame, but also effectively prevents the influence of debris and garbage on the operation of the gate device, thereby ensuring the smooth progress of water conservancy irrigation.

[0061] A method for using a water conservancy irrigation gate device comprises the following steps:

When it is necessary to open the gate to release water, the driving motor 6 drives the screw 5 to rotate, and the screw 5 drives the top plate 2 and the gate 3 to move upward, and the water flows through the filter plate 4 to flow to the farmland canal, and the filter plate 4 filters the debris and garbage in the water flow to avoid the blockage of the water flow caused by the accumulation of garbage, and the silt and mud carried by the water flow gradually accumulate in the triangular groove 11;

[0063] S2. When the top plate 2 moves upward, the top plate 2 drives the chain 16 to run through the connecting rod 23. The chain 16 drives the rotating shaft 14 to rotate under the cooperation of the two sprockets 15. The rotating shaft 14 drives the bevel gear 27 to rotate through the bevel gear ring 28. The gearbox 30 adjusts the rotation speed of the bevel gear 27 to drive the threaded rod 31. The threaded rod 31 drives the nut block 32 to move upward. The cooperation of the nut block 32 and the connecting rod 34 drives the blocking plate 33 to move outward, just closing the connecting hole 13 to prevent excessive sediment and silt from accumulating in the collecting tank 12.

[0064] S3. When the gate 3 needs to be closed, the top plate 2 and the gate 3 move downward, and the triangular bar 10 scrapes the debris and garbage filtered on one side of the filter plate 4 downward to prevent the debris and garbage from clogging the filter plate 4. When the gate 3 and the filter plate 4 move downward, the rotating shaft 14 is driven to rotate in the opposite direction, and the rotating shaft 14 drives the two blocking plates 33 to move toward the middle to release the blockage of the connecting hole 13. When the triangular bar 10 extends into the triangular groove 11, the silt and mud in the triangular groove 11 can be squeezed into the collecting tank 12 to prevent the silt and mud in the triangular groove 11 from affecting the closure of the gate 3.

[0065] S4, while the rotating shaft 14 rotates, the stirring blade 18 is driven to rotate, and the stirring blade 18 can stir the sediment and silt settled in the collecting tank 12, so that the sediment and silt are mixed with the water in the collecting tank 12, and then the water pump 19 pumps the sediment and silt in the collecting tank 12 into the silt tank 41, and the suction force generated during the extraction process can further remove the sediment and silt in the triangular groove 11, and the accumulated sediment and silt contain rich organic matter and inorganic elements, which can be used as soil conditioners for fertilizing farmland, can change the physical and chemical properties of the soil, increase the permeability and water retention capacity of the soil, and improve the fertility and water and fertilizer retention capacity of the soil;

[0066] S5. In addition, when the gates are opened on the top plate 2 and the gate 3, the focusing plate 39, pushed by the water flow, drives the guide rod 38 and the inclined scraper 37 to move toward the filter plate 4 until the inclined scraper 37 is close to the filter plate 4, thereby preventing mud and silt from falling into the triangular groove 11; when the gate 3 moves downward, the triangular bar 10 can not only scrape off the debris and garbage on one side of the filter plate 4, but also when the triangular bar 10 moves downward, the inclined surface of the triangular bar 10 cooperates with the inclined surface 40 to drive the inclined scraper 37 to move away from the filter plate 4. The cooperation between the triangular bar 10 and the inclined scraper 37 can scrape off the debris and garbage scraped off by the triangular bar 10, thereby preventing the garbage on the triangular bar 10 from entering the triangular groove 11.

[0067] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 6 and the water pump 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
