Description

Technical Field

[0001] This invention relates to the field of gate equipment technology, and in particular to a high-efficiency, energy-saving, and antifreeze gate. Background Technology

[0002] In hydraulic engineering, sluice gates are an important component of hydraulic structures. They can close or fully or partially open the orifices of structures as needed to regulate upstream and downstream water levels and flow rates, thereby achieving benefits such as flood control, irrigation, water supply, power generation, navigation, and the passage of logs and rafts. They can also be used to remove floating debris, silt, ice, etc., or provide necessary conditions for the maintenance of related structures and equipment. Cast iron sluice gates are typically installed at the inlet and outlet of water intake and conveyance structures, and their functions and benefits are realized through flexible and reliable opening and closing, ensuring the safety of the structures.

[0003] Among existing patents, one application, "CN201910012298.0," describes a "pre-embedded polarized aeration anti-freezing gate." This gate not only uses aeration to prevent icing but also employs both vibration crushing and electric heating to remove ice from the gate. However, these de-icing methods consume a significant amount of heat. Furthermore, due to the ice buildup on the gate surface, prolonged vibration de-icing can easily deform the gate's surface, affecting its sealing effect and reducing its airtightness. Therefore, a more efficient and energy-saving anti-freezing gate is needed. Summary of the Invention

[0004] The purpose of this application is to provide a high-efficiency, energy-saving, and antifreeze gate to solve the problems mentioned in the background art, such as the large amount of heat consumed during the de-icing and antifreeze process, and the fact that vibration de-icing can easily deform the surface of the gate and affect its sealing effect.

[0018] In summary, the technical effects and advantages of this invention are as follows:

[0019] In this invention, an L-shaped plate is used to support the movement of the driving plate while maintaining the fixed support of the first and second guide plates. A water-sealing strip prevents water from flowing out from both sides of the gate during overall swaying. A hydraulic telescopic cylinder is used; activating the cylinder changes the height of the driving plate. The driving plate influences the movement trajectory of the rollers within the first and second guide plates. When the rollers are at the turning point between the first and second guide plates, the gate is perpendicular to the baffle. The lower surface of the circular base plate presses against the surface of the semi-circular sealing strip for sealing. When the hydraulic telescopic cylinder controls the plate to continue descending, the roller moves along the inner wall below the first and second guide plates. Because the lower surface of the inner wall of the first and second guide plates has a gradually descending arc, the roller and the driving rod as a whole deflect at an angle around the central axis of the semi-circular base plate, causing the gate to deflect at an angle until the roller stops moving at the foremost point of the inner wall of the arc-shaped gradually changing slope. When the hydraulic telescopic cylinder controls the plate to rise, by setting the arc-shaped gradually changing slope, the roller moves along the inner wall of the plate as it rises. During the process, the roller moves towards the rear of the inner wall of the gradually tapering curved surface. Since the roller is also located within the first guide plate, it is driven to move towards the rear side of the inner wall below the first guide plate until it reaches the turning point of the first guide plate. During this process, the gate completes a certain angle of back-and-forth swing, causing the gate to move as a whole. This prevents ice from forming and solidifying in the gap between the gate and the U-shaped mounting plate, while allowing external water to flush the surface of the gate, preventing icing. The roller continues to rise under the action of the driving plate, and the inner wall space above the first guide plate does not interfere with it. By setting a driving rod and steel bars to maintain the driving connection with the gate, by setting a clearance hole to allow space clearance, and by setting a one-way valve to prevent liquid inside the gate from flowing back into the vent pipe after the vent pipe is inserted into the one-way valve, and at the same time to prevent liquid inside the gate from flowing out, by setting an insertion hole to provide space for the vent pipe to be installed, the gate can swing back and forth at a certain angle through the above structure. When the gate moves, it is not conducive to ice freezing in the gap between the gate and the U-shaped mounting plate, and at the same time, the external water source can wash the surface of the gate to prevent icing.

[0020] By setting the first and second teeth to mesh, when the semicircular base plate rotates, it drives the first tooth to rotate. The rotation of the first tooth drives the second tooth and the swing column to rotate as a whole. As the semicircular base plate swings back and forth, it drives the swing column and the swashplate to swing back and forth. By setting the swashplate, the horizontal distance between the first ball head and the pressure tube is changed. By setting the air inlet pipe, outside air is introduced. By setting the one-way valve, gas in the pressure tube is prevented from being discharged through the air inlet pipe. By setting the exhaust pipe, the gas is delivered to the gate to generate bubbles, which causes the antifreeze in the gate to flow and mix. By setting the piston rod, the gas inside the pressure tube is kept in a constant state. The gate's sealing is achieved through a connecting rod. The movement of the first ball joint drives the second ball joint, which in turn pushes the fixed block and piston rod to change their positions. Small holes facilitate the discharge of large amounts of air bubbles generated inside the gate. A trash can is included, which swings with the gate to collect floating debris. The gate's inner wall is filled with antifreeze to lower its freezing point, preventing it from freezing easily. This structure prevents excessive heat from freezing and avoids de-icing through gate vibration, ensuring the gate remains undeformed and maintaining its airtightness.

[0021] The trash can is preferably made of stainless steel wire to prevent rusting. It drains water to collect trash. The gate and steel bars are coated with anti-rust and antifreeze paint to prevent them from rusting upon contact with water. The curvature of the lower surface of the semi-circular base plate matches the curvature of the upper surface of the semi-circular sealing strip and baffle to achieve a better fit and seal. The distance between the inner walls of the first guide plates is the same as the diameter of the rollers, ensuring that the rollers always move along the inner walls of the first guide plates. The rollers are preferably made of a material with high wear resistance to prevent wear from the inner walls of the first guide plates over a long period of use. The driving plate and the first guide plates are preferably made of high-strength materials. During the process of the hydraulic telescopic cylinder driving the driving plate, the driving rod and gate are supported and lifted without deformation. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Reference Figures 1-8The high-efficiency energy-saving antifreeze gate shown includes a U-shaped mounting plate 1 and a gate 2. The gate 2 is installed inside the U-shaped mounting plate 1. An L-shaped plate 3 is fixedly connected to the upper surface of the U-shaped mounting plate 1. A support plate 4 is fixedly connected to the upper surface of the L-shaped plate 3. A hydraulic telescopic cylinder 5 is fixedly connected to the upper surface of the support plate 4. A baffle 7 is fixedly connected to the inner bottom wall of the U-shaped mounting plate 1. Water sealing strips 10 are fixedly connected to the inner walls of both the left and right sides of the U-shaped mounting plate 1. An antifreeze mechanism is fixedly connected to the output end of the hydraulic telescopic cylinder 5.

[0034] The antifreeze mechanism includes a drive plate 11 fixedly connected to the output end of the hydraulic telescopic cylinder 5, a first guide plate 12 fixedly connected to the inner wall of the left L-shaped plate 3, and a second guide plate 14 fixedly connected to the inner wall of the right L-shaped plate 3. Rollers 15 are installed inside the drive plate 11, the first guide plate 12, and the second guide plate 14. The opposite surfaces of a pair of rollers 15 are rotatably connected to the same drive rod 13. A steel strip 30 is fixedly connected to the surface of the drive rod 13. The bottom end of the steel strip 30 is fixedly connected to the upper surface of the gate 2.

[0035] The inner bottom wall of the driving plate 11 is set as an arc-shaped gradually changing inclined surface 17;

[0036] A semi-circular sealing strip 9 is fixedly connected to the upper surface of the baffle 7, and a semi-circular bottom plate 8 is fixedly connected to the lower surface of the gate 2. The upper surfaces of the baffle 7 and the semi-circular sealing strip 9 are provided with the same clearance hole 31. A one-way switch valve 16 is fixedly connected to the inner bottom wall of the gate 2. The inner bottom wall of the gate 2 and the surface of the semi-circular bottom plate 8 are provided with the same insertion hole 33. A bubble assembly is fixedly connected to the surface of the semi-circular bottom plate 8.

[0037] Using the above structure, the L-shaped plate 3 provides support for the movement of the driving plate 11 while maintaining the fixed support of the first guide plate 12 and the second guide plate 14. The water-sealing strip 10 prevents water from flowing out from both sides of the gate 2 during overall swaying. The hydraulic telescopic cylinder 5, when activated, causes a change in the height of the driving plate 11. The driving plate 11 influences the movement trajectory of the roller 15 within the first guide plate 12 and the second guide plate 14. When the roller 15 is positioned between the first guide plate 12 and the second guide plate 14... At the turning point within 4, the gate 2 is perpendicular to the baffle 7, and the lower surface of the semi-circular bottom plate 8 presses against the surface of the semi-circular sealing strip 9 for sealing. When the hydraulic telescopic cylinder 5 controls the driving plate 11 to continue descending, the roller 15 moves on the inner wall below the first guide plate 12 and the second guide plate 14. Since the lower surface of the inner wall of the first guide plate 12 and the second guide plate 14 has a gradually descending arc, the roller 15 and the driving rod 13 are deflected at an angle around the central axis of the semi-circular bottom plate 8, causing the gate 2 to deflect at an angle until the roller 15 is at the foremost position on the inner wall of the arc-shaped gradually changing slope 17. When the hydraulic telescopic cylinder 5 controls the upward movement of the plate 11, the roller 15 moves towards the rear of the inner wall of the arc-shaped gradient slope 17 as the plate 11 rises. Since the roller 15 is also located within the first guide plate 12, it moves towards the rear of the lower inner wall of the first guide plate 12 until it reaches the turning point of the first guide plate 12. During this process, the gate 2 swings back and forth at a certain angle, causing the gate 2 to move as a whole. This prevents ice from forming and solidifying in the gap between the gate 2 and the U-shaped mounting plate 1, while also allowing the outer... The water source washes the surface of the gate 2 to prevent freezing. The roller 15 will continue to rise under the action of the drive plate 11. The inner wall space above the first guide plate 12 will not interfere with it. By setting the drive rod 13 and the steel bar 30, the drive connection with the gate 2 is maintained. By setting the clearance hole 31, space clearance is provided. By setting the one-way switch valve 16, after the exhaust pipe 22 is inserted into the one-way switch valve 16, the liquid in the gate 2 is prevented from flowing back into the exhaust pipe 22, and the liquid in the gate 2 is also prevented from flowing out. By setting the insertion hole 33, space is provided for the installation of the exhaust pipe 22.

[0038] As a preferred embodiment of this example, please refer to the appendix. Figure 7 The bubble assembly includes a first tooth 18 fixedly connected to the surface of the semi-circular base plate 8. The first tooth 18 is installed inside the clearance hole 31. The inner wall of the baffle 7 is rotatably connected to a swing column 24. One end of the swing column 24 is fixedly connected to a swashplate 19. Multiple second teeth 23 are fixedly connected to the surface of the swing column 24. The first tooth 18 meshes with the second tooth 23.

[0039] By setting the first tooth 18 to mesh with the second tooth 23, when the semicircular base plate 8 rotates, it drives the first tooth 18 to rotate. The rotation of the first tooth 18 drives the second tooth 23 and the swing column 24 to rotate as a whole. As the semicircular base plate 8 swings back and forth, it drives the swing column 24 and the swashplate 19 to swing back and forth. By setting the swashplate 19, the horizontal distance between the first ball head 25 and the pressure tube 20 is changed.

[0040] As a preferred embodiment of this example, please refer to the appendix. Figure 6 , Figure 7 , Figure 8 The bubble assembly also includes a first ball head 25 that is rolled and connected to the inner wall of the swashplate 19. An air inlet pipe 21 is fixedly connected to the inner wall of the U-shaped mounting plate 1. A one-way valve 6 is fixedly connected to the surface of the air inlet pipe 21. A pressure pipe 20 is rotatably connected to one end of the air inlet pipe 21 near the swashplate 19. An exhaust pipe 22 is fixedly connected to the inner wall of the pressure pipe 20. The exhaust pipe 22 is installed inside the insertion hole 33. The position of the exhaust pipe 22 corresponds to the position of the one-way switch valve 16. Through holes are opened on the surfaces of the baffle 7 and the semi-circular sealing strip 9. The surface of the pressure pipe 20 is sealed and fitted to the lower surface of the through hole.

[0041] By setting an air intake pipe 21, outside air is introduced. By setting a one-way valve 6, gas in the pressure pipe 20 is prevented from being discharged through the air intake pipe 21. By setting an exhaust pipe 22, gas is transported to the gate 2 to generate bubbles, so that the antifreeze in the gate 2 flows and mixes.

[0042] As a preferred embodiment of this example, please refer to the appendix. Figure 6 , Figure 7 , Figure 8 The bubble assembly also includes a piston rod 29 sleeved on the inner wall of the pressure tube 20. The end of the piston rod 29 near the air inlet tube 21 is adapted to the inner wall of the pressure tube 20. The end of the piston rod 29 away from the air inlet tube 21 is fixedly connected to a fixing block 28. The inner wall of the fixing block 28 is rolledly connected to a second ball head 27. The surface of the second ball head 27 and the first ball head 25 are fixedly connected to the same connecting rod 26.

[0043] By setting the piston rod 29, the gas inside the pressure tube 20 is kept sealed. By setting the connecting rod 26, the movement of the first ball head 25 drives the second ball head 27 to be stressed through the connecting rod 26, thereby pushing the fixed block 28 and the piston rod 29 to change their positions.

[0044] As a preferred embodiment of this example, please refer to the appendix. Figure 1 The upper surface of the gate 2 has multiple small holes, and multiple trash cans 32 are fixedly connected to the front of the gate 2. The inner wall of the gate 2 is filled with antifreeze.

[0045] By setting small holes, it is easy to discharge a large number of air bubbles generated inside the gate 2. By setting a trash can 32, the trash can 32 swings with the gate 2, which can collect the trash floating on the water surface into the trash can 32. By setting the inner wall of the gate 2 to be filled with antifreeze, the freezing point of the gate 2 is lowered, making it less likely to freeze.

[0046] As a preferred embodiment of this example, please refer to the appendix. Figure 2 The trash can 32 is preferably made of stainless steel wire.

[0047] The trash can 32 is preferably made of stainless steel wire to prevent it from rusting and allows for the collection of trash by draining water.

[0048] As a preferred embodiment of this example, please refer to the appendix. Figure 5 The surfaces of gate 2 and steel bar 30 are coated with anti-rust and anti-freeze paint.

[0049] By coating the surfaces of the gate 2 and steel bar 30 with anti-rust and antifreeze paint, the gate 2 and steel bar 30 are prevented from rusting upon contact with water.

[0050] As a preferred embodiment of this example, please refer to the appendix. Figure 2 The curvature of the lower surface of the semi-circular base plate 8 is matched with the curvature of the upper surface of the semi-circular sealing strip 9 and the baffle 7.

[0051] By setting the curvature of the lower surface of the semi-circular base plate 8 to match the curvature of the upper surface of the semi-circular sealing strip 9 and the baffle 7, a better sealing effect can be achieved.

[0052] As a preferred embodiment of this example, please refer to the appendix. Figure 3 , Figure 4 The distance between the inner walls of the first guide plate 12 is the same, and the distance between the inner walls of the first guide plate 12 is the same as the diameter of the roller 15.

[0053] By setting the distance between the inner walls of the first guide plate 12 to be the same, and the distance between the inner walls of the first guide plate 12 to be the same as the diameter of the roller 15, the roller 15 is always guided to move along the inner wall of the first guide plate 12.

[0054] As a preferred embodiment of this example, please refer to the appendix. Figure 3 , Figure 4 The roller 15 is preferably made of a material with high wear resistance and strength, and the drive plate 11 and the first guide plate 12 are preferably made of a material with high strength and will not deform.

[0055] By setting the roller 15 to be made of a material with high wear resistance, wear on the inner wall of the first guide plate 12 is prevented from occurring due to long-term use of the roller 15. The driving plate 11 and the first guide plate 12 are preferably made of a material with high strength. During the process of the hydraulic telescopic cylinder 5 driving the driving plate 11, the driving rod 13 and the gate 2 are lifted and supported without deformation.

[0056] The working principle of this invention is as follows: During use, the hydraulic telescopic cylinder 5 is activated. The output end of the hydraulic telescopic cylinder 5 causes a change in the height of the driving plate 11. When the roller 15 is located at the junction between the first guide plate 12 and the second guide plate 14, the gate 2 is perpendicular to the baffle 7. The lower surface of the semi-circular bottom plate 8 presses against the surface of the semi-circular sealing strip 9 for sealing. When the hydraulic telescopic cylinder 5 controls the driving plate 11 to continue descending, the roller 15 moves along the inner wall below the first guide plate 12 and the second guide plate 14. Because the lower surface of the inner wall of the first guide plate 12 and the second guide plate 14 has a gradually descending arc, the roller 15 and the driving rod 13 as a whole deflect at an angle around the central axis of the semi-circular bottom plate 8, causing the gate 2 to deflect at an angle. The roller 15 stops moving when it reaches the foremost point of the inner wall of the arc-shaped gradient slope 17. When the hydraulic telescopic cylinder 5 controls the lifting of the plate 11, the arc-shaped gradient slope 17 causes the roller 15 to move towards the rear of the inner wall of the arc-shaped gradient slope 17 as the plate 11 rises. Since the roller 15 is also located within the first guide plate 12, it moves towards the rear side of the inner wall below the first guide plate 12 until it reaches the turning point of the first guide plate 12. The hydraulic telescopic cylinder 5 is then controlled to repeat this movement process multiple times, causing the gate 2 to swing back and forth at a certain angle. During this movement, the gate 2 is protected from freezing and solidification at the gap between it and the U-shaped mounting plate 1, while allowing external water to wash over the surface of the gate 2, preventing... To prevent icing, the gate 2 is filled with antifreeze to lower its freezing point, making it less prone to freezing. The antifreeze inside the gate 2 flushes the inner wall of the gate 2, eliminating the need to fill it completely, thus saving antifreeze while achieving an antifreeze effect. The swinging of the gate 2 causes the semi-circular base plate 8 to swing back and forth. Since the first tooth 18 and the second tooth 23 are engaged, the rotation of the semi-circular base plate 8 causes the first tooth 18 to rotate. The rotation of the first tooth 18 causes the second tooth 23 and the swing column 24 to rotate as a whole. The movement of the swing column 24 causes the swashplate 19 to swing back and forth. The rotation of the swashplate 19 changes the horizontal distance between the first ball head 25 and the pressure tube 20. By setting the piston rod 29, the gas inside the pressure tube 20 is kept sealed. The movement of the first ball head 25 allows... The connecting rod 26 drives the second ball head 27 to receive force, which in turn pushes the fixed block 28 and piston rod 29 to change their positions. When the piston rod 29 moves towards the swashplate 19, it draws outside air into the pressure pipe 20 through the intake pipe 21. When the piston rod 29 moves towards the intake pipe 21, it pushes gas into the gate 2 through the exhaust pipe 22, generating bubbles. This causes the antifreeze in the gate 2 to mix and flow. As the gate 2 descends vertically from a high position, the exhaust pipe 22 is inserted into the one-way valve 16. After the exhaust pipe 22 is inserted, the one-way valve 16 prevents the antifreeze in the gate 2 from flowing back into the exhaust pipe 22. At the same time, after the exhaust pipe 22 separates from the one-way valve 16, it prevents the antifreeze in the gate 2 from flowing out.As the gate 2 swings, it causes the semi-circular bottom plate 8 and the exhaust pipe 22 to swing as a whole. The exhaust pipe 22, under pressure, causes the pressure pipe 20 to rotate adaptively. The roller 15 continues to rise under the action of the driving plate 11. The inner wall space above the first guide plate 12 does not interfere with it. When the roller 15 moves to the rear inner wall of the arc-shaped gradually changing slope 17, at the turning point between the first guide plate 12 and the second guide plate 14, it cooperates with the inner wall of the first guide plate 12 to maintain stable as the driving plate 11 continues to rise. During this process, the semi-circular bottom plate 8 below the gate 2 is disengaged from the surface of the semi-circular sealing strip 9 through the driving rod 13 and steel strip 30, achieving drainage. This structure prevents excessive heat from causing freezing and avoids de-icing through gate 2 vibration, ensuring that the gate 2 does not deform and guaranteeing its sealing performance.
