A floating gate with speed regulation function

Abstract

The present invention relates to the field of gate technology, and in particular to a floating gate with a speed regulation function. The technical problem of the present invention is that the weight of the gate will affect the burden when opening and the resistance to water flow impact, and the current gate is not convenient for adjusting the weight of the gate when opening and closing when in use, which makes it difficult for the gate to reduce the opening burden while maintaining the water-blocking weight, and the water flow will cause the gate to vibrate in the door frame, causing the gate to be unstable, resulting in poor water-blocking effect of the gate. A floating gate with a speed regulation function includes a door frame, and two jacks are provided in the middle of the door frame. When closing, the gate's own weight is increased by sucking in water and discharging air, and when opening, the weight is reduced by discharging water and sucking in air, thereby adjusting the weight of the gate when opening and closing, so that the gate can maintain the water-blocking weight while reducing the opening burden, thereby enhancing the gate's water-blocking effect.

Description

Technical Field

[0001] The present invention relates to the technical field of gates, and in particular to a floating gate with a speed regulation function. Background Art

[0002] Gates originate from the need for water flow control in water conservancy projects and are usually used to intercept water flow, regulate water levels and manage flow. Traditional gates are mainly made of cast iron and steel. When opening and closing, the existing integrated mechanical gates are driven by motors to drive threaded rods to lift and close the gates. By adjusting the speed of the motor, the opening and closing speed of the gates can also be adjusted.

[0003] Since the weight of the gate affects the burden when opening and its ability to resist the impact of water flow, the current gate is not easy to adjust the weight of the gate when opening and closing, which makes it difficult to reduce the opening burden while maintaining the water-blocking weight. In addition, the water flow will cause the gate to vibrate in the door frame, resulting in the gate being unstable, resulting in poor water-blocking effect of the gate. Summary of the Invention

[0004] In order to overcome the above shortcomings, the present invention provides a floating gate with a speed regulation function, which can adjust the weight of the gate during opening and closing so that the gate can reduce the opening burden while maintaining the water-blocking weight, and fix the gate on the door frame to make the gate more stable, thereby enhancing the water-blocking effect of the gate.

[0005] The technical solution is: a floating gate with speed regulation function, including a door frame, two sockets are provided in the middle of the door frame, a top beam is fixed to the door frame, a gate is slidably connected to the door frame, a cavity is provided in the gate, an air vent is provided at the top of the gate, a water hole is provided at the bottom of the gate, the air vent and water hole of the gate are connected to the cavity of the gate, a channel is left between the gate and the bottom of the door frame, three rollers are rotatably connected to both sides of the gate, six rollers are slidably connected to the door frame, and a lifting mechanism for lifting the gate is provided on the top beam.

[0006] Furthermore, a frame is provided on the gate.

[0007] Furthermore, the lifting mechanism includes a casing, the casing is fixed to the top beam, a servo motor is fixed to the casing, a worm is fixed to the output shaft of the servo motor, the worm is rotatably connected to the casing, a threaded sleeve is rotatably connected inside the casing, a worm wheel is fixed to the threaded sleeve, the worm wheel is engaged with the worm, a threaded rod is threadedly connected inside the threaded sleeve, a lifting frame is fixed to the bottom of the threaded rod, the lifting frame is slidably connected to the gate, and a compensation component for compensating for the weight of the gate is provided on the lifting frame.

[0008] Furthermore, the compensation assembly includes a piston plate, which is fixed to the lifting frame. The piston plate divides the cavity of the gate into two parts, upper and lower parts, so that the air vent of the gate is connected to the lower cavity of the gate, and the water hole of the gate is connected to the upper cavity of the gate. A guide pipe is slidably connected to the water hole of the gate, the bottom of the guide pipe is fixed to the door frame, and the guide pipe is connected to the upper cavity of the gate.

[0009] Furthermore, the air vents of the door frame and the bottom of the guide pipe are both provided with filter screens.

[0010] Furthermore, a protective cover is also included.

[0011] Furthermore, an anti-vibration mechanism is included, which is provided on the lifting frame and is used to reduce the vibration of the gate. The anti-vibration mechanism includes a guide frame, which is fixed to the lifting frame. Two guide sleeves are fixed to the top of the gate, and locking columns are slidably connected in the two guide sleeves. The ends of the two locking columns away from each other are respectively in contact with the two jacks of the door frame, and the ends of the two locking columns close to each other are fixed with contact frames. The two contact frames are both obliquely arranged, and the sides of the two contact frames close to each other are respectively in contact with the two ends of the guide frame, and tension springs are connected between the two locking columns and the two guide sleeves.

[0012] Furthermore, it also includes a blood stasis discharge mechanism, which is arranged in the protective cover and is used to discharge silt. The blood stasis discharge mechanism includes a lifting frame, which is slidably connected to the lower part of the protective cover, the top of the lifting frame is in contact with the lifting frame, and the bottom of the lifting frame is fixed with a baffle, which is in contact with the gate and the door frame, and a pressure spring is connected between the lifting frame and the protective cover.

[0013] Furthermore, a sealing mechanism is included, which is provided on the guide sleeve and is used to seal the gap between the gate and the door frame. The sealing mechanism includes a piston cylinder, and the two piston cylinders are respectively fixed to the top of the two guide sleeves. Piston rods are slidably connected in the two piston cylinders, and the two piston rods are respectively fixed to the two locking columns. Two inflatable sealing strips are installed on the gate, and the two inflatable sealing strips are in contact with the door frame. Connecting pipes are connected between the two inflatable sealing strips and the two piston cylinders.

[0014] The beneficial effects are: 1. When the gate is closed, water is sucked in and air is discharged through the gate to increase the gate's own weight, and when the gate needs to be opened, water is discharged and air is sucked in through the gate to reduce the weight, thereby adjusting the weight of the gate when opening and closing, so that the gate can reduce the opening burden while maintaining the water-blocking weight, thereby enhancing the water-blocking effect of the gate.

[0015] 2. After closing the gate, insert the locking column into the gate's socket to fix the gate on the door frame, making the gate more stable and further enhancing the gate's water-blocking effect; the lifting frame drives the baffle to move upward, so that the water flow at the bottom carries the silt out from the channel between the door frame and the gate, and then the accumulated silt is cleared by the water flow, making the subsequent opening of the gate smoother, thereby improving the gate's opening efficiency, and the lifting frame can be regularly controlled to move upward a certain distance to open the baffle, thereby regularly clearing the silt accumulated at the bottom of the gate.

[0016] 3. By inflating the inflatable sealing strip after closing the gate, the gate can be sealed without affecting the opening and closing resistance of the gate, making it difficult for water to flow out from the gap between the gate and the door frame, thereby further enhancing the water-blocking effect of the gate.

DETAILED DESCRIPTION

[0029] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0030] Example 1: A floating gate with speed regulation function, such as Figure 1-Figure 5 As shown, it includes a door frame 1, two jacks are provided in the middle of the door frame 1, a top beam 2 is connected to the door frame 1 by bolts, a gate 3 is slidably connected to the door frame 1, the door frame 1 is used to guide and support the gate 3, the gate 3 is used to block the water flow, a cavity is provided in the gate 3, an air vent is provided on the top of the gate 3, the air vent of the gate 3 is used for the air in and out, a water hole is provided at the bottom of the gate 3, the water hole of the gate 3 is used for the water in and out, the air vent and the water hole of the gate 3 are connected with the cavity of the gate 3, a channel is left between the gate 3 and the bottom of the door frame 1, three rollers 4 are rotatably connected to both sides of the gate 3, six rollers 4 are slidably connected to the door frame 1, the rollers 4 are used to reduce the friction between the gate 3 and the door frame 1, and a lifting mechanism 5 for lifting the gate 3 is provided on the top beam 2.

[0031] A frame is provided on the gate 3, and the frame of the gate 3 can prevent the gate 3 from being deformed.

[0032] The lifting mechanism 5 includes a casing 51, which is connected to the top beam 2 by bolts. A servo motor 52 is connected to the casing 51 by bolts. A worm 53 is connected to the output shaft of the servo motor 52 by a keyway. The worm 53 is rotatably connected to the casing 51. A threaded sleeve 55 is rotatably connected to the casing 51. A worm gear 54 is connected to the threaded sleeve 55 by bolts. The worm gear 54 engages with the worm 53. A threaded rod 56 is threadedly connected to the threaded sleeve 55. A lifting frame 57 is connected to the bottom of the threaded rod 56 by bolts. The lifting frame 57 is slidably connected to the gate 3. The lifting frame 57 is used to open and close the gate 3. A compensation component 6 for compensating for the weight of the gate 3 is provided on the lifting frame 57.

[0033] The compensation assembly 6 includes a piston plate 61, which is connected to the lifting frame 57 by bolts. The piston plate 61 divides the cavity of the gate 3 into two parts, the upper and lower parts. The piston plate 61 is used to adjust the cavity ratio of the upper and lower parts of the gate 3, so that the air vent of the gate 3 is connected to the lower cavity of the gate 3, and the water hole of the gate 3 is connected to the upper cavity of the gate 3. A guide pipe 62 is slidably connected to the water hole of the gate 3. The bottom of the guide pipe 62 is connected to the door frame 1 by bolts, and the guide pipe 62 is connected to the upper cavity of the gate 3.

[0034] The air vents of the door frame 1 and the bottom of the guide tube 62 are both provided with filter screens, and the air vents of the door frame 1 and the filter screens of the guide tube 62 are used to block debris.

[0035] A protective cover 7 is also included, which is used to protect the threaded rod 56.

[0036] Initially, the upper cavity of the gate 3 is filled with water, and the bottom of the guide tube 62 is immersed in water. When the gate 3 needs to be lifted, the operator starts the servo motor 52. The rotation of the output shaft of the servo motor 52 drives the worm 53 to rotate. The rotation of the worm 53 drives the threaded sleeve 55 to rotate through the worm gear 54. The rotation of the threaded sleeve 55 drives the lifting frame 57 to move upward through the threaded rod 56. The movement of the lifting frame 57 drives the piston plate 61 to move together. When the piston plate 61 moves to the upper part of the gate 3, it squeezes the water in the upper cavity of the gate 3. The water in the upper cavity of the gate 3 is squeezed and discharged from the guide tube 62 through the water hole of the gate 3, so that the weight of the gate 3 is reduced. At the same time, the gate 3 generates negative pressure in the cavity below the gate 3, so that air is sucked into the cavity below the gate 3 from the vent hole, which increases the buoyancy of the gate 3. Then the lifting frame 57 continues to move upward. At this time, the gate 3 moves upward under the action of the lifting frame 57 and the buoyancy of the gate 3. At the same time, the gate 3 reduces the friction between it and the door frame 1 through the roller 4, thereby opening the gate 3. At the same time, the opening speed of the gate 3 is adjusted by adjusting the rotation speed of the servo motor 52. When it is necessary to close the gate 3, the operator controls the output shaft of the servo motor 52 to reverse, so that the worm 53 is reversed. The reversal of the worm 53 drives the threaded sleeve 55 to reverse through the worm gear 54, so that the threaded rod 56 drives the lifting frame 57 to reverse. The lifting frame 57 moves downward to reset, and the lifting frame 57 moves downward to make the gate 3 move downward to reset. After the gate 3 is reset, the lifting frame 57 continues to move downward to drive the piston plate 61 to move together. The downward movement of the piston plate 61 will squeeze the air in the lower cavity of the gate 3, so that the air is discharged through the vent of the gate 3. At the same time, the upper cavity of the gate 3 generates negative pressure, so that water enters the upper cavity of the gate 3 through the guide pipe 62 and the water through hole of the gate 3. At the same time, the filter screens at the bottom of the vent of the gate 3 and the guide pipe 62 will intercept the debris in the water and the air, and the vent of the gate 3 and the guide pipe 62 will backwash the gate 3 and the guide pipe 62 when they are venting and draining respectively. 2, and then clean the debris attached to the filter; when the upper cavity of the gate 3 is filled with water, the gravity of the gate 3 will be increased. In this way, when the gate 3 is closed, water is sucked in and air is discharged through the gate 3 to increase the weight of the gate 3, and when the gate 3 needs to be opened, water is discharged and air is sucked in through the gate 3 to reduce the weight, thereby adjusting the weight of the gate 3 when opening and closing, so that the gate 3 can reduce the opening burden while maintaining the water-blocking weight, thereby enhancing the water-blocking effect of the gate 3; when the gate 3 blocks water, the skeleton on the gate 3 makes it difficult for the gate 3 to deform, and the threaded rod 56 is shielded by the protective cover 7, thereby preventing debris such as weeds and plastic bags from being entangled in the threaded rod 56.

[0037] Example 2: Based on Example 1, Figures 1-9As shown, it also includes an anti-vibration mechanism 8, which is arranged on the lifting frame 57 and is used to reduce the vibration of the gate 3. The anti-vibration mechanism 8 includes a guide frame 81, which is connected to the lifting frame 57 by bolts. The top of the gate 3 is connected to two guide sleeves 82 by bolts, and locking columns 83 are slidably connected in the two guide sleeves 82. The ends of the two locking columns 83 that are away from each other are respectively in contact with the two sockets of the door frame 1. The locking columns 83 are used to be inserted into the sockets of the door frame 1. The ends of the two locking columns 83 that are close to each other are both connected to contact frames 84 by bolts. The two contact frames 84 are both obliquely arranged, and the sides of the two contact frames 84 that are close to each other are respectively in contact with the two ends of the guide frame 81. The guide frame 81 is used to drive the locking columns 83 to move by squeezing the contact frames 84, and tension springs 85 are connected between the two locking columns 83 and the two guide sleeves 82.

[0038] It also includes a blood sludge discharge mechanism 9, which is arranged in the protective cover 7 and is used to discharge silt. The blood sludge discharge mechanism 9 includes a lifting frame 91, which is slidably connected to the lower part of the protective cover 7. The top of the lifting frame 91 is in contact with the lifting frame 57, and the bottom of the lifting frame 91 is connected to a baffle 92 by bolts. The baffle 92 is in contact with the gate 3 and the door frame 1. The lifting frame 91 is used to drive the baffle 92 to move by the extrusion of the lifting frame 57. A pressure spring 93 is connected between the lifting frame 91 and the protective cover 7.

[0039] The two locking posts 83 are no longer respectively against the two insertion holes of the gate 3, so that the gate 3 can be opened laterally. When the gate 3 is closed, the lifting frame 57 moves downward to squeeze the lifting frame 91 to reset, and the pressure spring 93 returns to its initial state, so that the baffle 92 blocks the passage between the door frame 1 and the gate 3 again, thereby blocking the water flow.

[0040] Example 3: Based on Example 2, Figures 1-11 As shown, a sealing mechanism 10 is also included, which is provided on the guide sleeve 82 and is used to seal the gap between the gate 3 and the door frame 1. The sealing mechanism 10 includes a piston cylinder 101, and the two piston cylinders 101 are respectively connected to the top of the two guide sleeves 82 by bolts. The two piston cylinders 101 are slidably connected with piston rods 102, and the two piston rods 102 are respectively connected to the two locking columns 83 by bolts. Two inflatable sealing strips 104 are installed on the gate 3, and the two inflatable sealing strips 104 are in contact with the door frame 1. The inflatable sealing strips 104 are used to fill the gap between the door frame 1 and the gate 3. The two inflatable sealing strips 104 are respectively connected to the two piston cylinders 101 with connecting pipes 103.

[0041] Initially, the inflatable sealing strip 104 is in an inflated state, so that the inflatable sealing strip 104 contacts the door frame 1. When the gate 3 needs to be opened, the two locking columns 83 will move toward each other. At the same time, the two locking columns 83 will respectively drive the two piston rods 102 to move together, so that negative pressure is generated in the piston cylinder 101. Subsequently, the air in the two inflatable sealing strips 104 enters the two piston cylinders 101 through the connecting pipes 103, so that the inflatable sealing strips 104 no longer contact the door frame 1. When the gate 3 is closed, the two locking columns 83 will move toward each other. The column 83 drives the two piston rods 102 to reset respectively, so that the two piston rods 102 squeeze the air in the two piston cylinders 101 respectively, so that the air in the two piston cylinders 101 enters the two inflatable sealing strips 104 respectively through the connecting pipes 103. In this way, the inflatable sealing strips 104 are inflated after closing the gate 3, and the gate 3 is sealed without affecting the opening and closing resistance of the gate 3, so that water is not easy to flow out from the gap between the gate 3 and the door frame 1, thereby further enhancing the water-blocking effect of the gate 3.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
