Description
Technical Field
[0001] This utility model relates to the field of water conservancy gate technology, and in particular to a river gate opening and closing device. Background Technology
[0002] In the field of water conservancy engineering, river gates are key facilities for controlling water flow. River gates are usually opened and closed by being equipped with lifting and opening devices.
[0003] Most existing opening and closing devices lack a mechanism to remove particulate impurities embedded in the grease within the outer threads of the lead screw used to drive the gate's opening and closing after long-term use. This results in the inability to quickly and easily clean the particulate impurities along with the grease when they cause obstruction to the screw's thread-driving effect, thus restoring the screw's thread-driving function. Consequently, workers must use external brushes to repeatedly and cumbersomely clean the particulate impurities. Although some opening and closing devices are equipped with cleaning mechanisms, these mechanisms still require additional drive units, making it impossible to utilize the drive units that are already necessary on the opening and closing device. This is detrimental to reducing the cost and power consumption of the opening and closing device. Utility Model Content
[0004] In view of this, the present invention provides a river gate opening and closing device to solve the problem that the existing opening and closing device lacks a mechanism to remove particulate impurities embedded in the lubricating grease in the outer circumferential thread of the lead screw used to drive the gate to open and close up and down after long-term use.
[0005] The technical solution proposed by this utility model is as follows: a river gate opening and closing device, specifically including a U-shaped support frame, a threaded sleeve rotatably mounted through the top side crossbeam of the U-shaped support frame, and a gear ring and a limiting ring respectively formed at the upper and lower ends of the threaded sleeve; an opening and closing screw that meshes with the threaded sleeve is disposed through the threaded sleeve; a drive assembly is fixedly mounted above the U-shaped support frame, and a drive gear is fixedly mounted on the power output shaft of the drive assembly, the drive gear meshing with the gear ring; a mounting column is fixedly suspended at the bottom of the power output shaft; on the mounting column... The welding assembly includes an installation ring, and a drive slip ring is slidably mounted on the mounting column. A T-shaped cleaning component is rotatably connected to the outer circumference of the installation ring. Stainless steel wires are evenly distributed on the outer side of the short arc-shaped support plate of the T-shaped cleaning component. A connecting rod is rotatably connected between the long support plate of the T-shaped cleaning component and the drive slip ring. A tightening bolt is threaded through the circumference of the installation ring, and the head end of the tightening bolt is in contact with the top of the mounting column. When the T-shaped cleaning component swings to switch to a horizontal unfolded state and rotates with the mounting column, the stainless steel brushes on it are in contact with the outer circumferential threads of the opening and closing screw.
[0006] Furthermore, a transmission box is welded to the top of the top side crossbeam of the U-shaped support frame. The top opening of the transmission box is covered with a box cover, and a circular through hole is provided on the box cover. The opening and closing screw slides through the circular through hole.
[0007] Furthermore, the drive gear and the gear ring are both located in the transmission box, and the bottom end of the housing of the drive assembly reducer is fixedly connected to the box cover.
[0008] Furthermore, it also includes a gate, which is slidably installed in the U-shaped channel. A U-shaped guide frame is fixedly connected to the top of the gate, and the two vertical guide shafts of the U-shaped guide frame are slidably engaged with the top side beam of the U-shaped guide frame.
[0009] Furthermore, the bottom end of the opening and closing screw is fixedly connected to the middle position of the top end of the gate.
[0010] Furthermore, a U-shaped support frame is fixedly installed at the top of the two vertical sidewalls of the U-shaped channel.
[0011] Furthermore, the bottom end of the power output shaft is rotatably engaged with the top side beam of the U-shaped support frame, and the gear ring and the limiting ring are respectively in contact with the upper and lower sides of the top side beam.
[0012] The river gate opening and closing device provided by this utility model has the following beneficial effects: 1. A T-shaped cleaning component is a brush cleaning mechanism for removing grease and particulate impurities embedded in it. This utility model can directly utilize this brush cleaning mechanism to efficiently and conveniently remove particulate impurities embedded in grease. Compared with existing technologies that lack a brush cleaning mechanism, this eliminates the tedious step of workers having to use an external brush to repeatedly brush and clean particulate impurities from the outer threads of the opening and closing screw, thus reducing the workload of workers. Since the mounting column is fixedly connected to the power output shaft, the brush cleaning mechanism can be directly driven by the existing and necessary drive assembly on the door opening and closing device. This allows the brush cleaning mechanism and the opening and closing screw to share the same drive unit for synchronous driving, eliminating the need to configure an additional drive unit for the brush cleaning mechanism, which helps to reduce the cost and power consumption of the opening and closing device to a certain extent.
[0013] 2. In the idle state, the T-shaped cleaning component is in a downward-swinging retracted state. In this state, the T-shaped cleaning component is in a vertical downward swinging position almost parallel to the opening and closing screw, and the stainless steel bristles on it are separated from the outer circumferential thread of the opening and closing screw. This can prevent the T-shaped cleaning component from failing to swing downward and retract when idle, causing the stainless steel bristles on it to remain in a sweeping cleaning state in contact with the outer circumferential thread of the opening and closing screw for a long time. As a result, even when the opening and closing screw is not stuck and there is no need to clean the particulate impurities in the grease in its outer circumferential thread, the stainless steel bristles will still continue to remove the grease and the particulate impurities in the grease, affecting the effective lubrication of the opening and closing screw by the grease under normal use.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Please refer to Figures 1 to 7 Example 1: This embodiment proposes a river gate opening and closing device, including a U-shaped support frame 3. A threaded sleeve 4 is rotatably installed through the middle of the top side crossbeam of the U-shaped support frame 3. The upper and lower ends of the threaded sleeve 4 are respectively formed with a gear ring 402 and a limiting ring 401. An opening and closing screw 202 is threaded through the threaded sleeve 4 and meshes with it for transmission. A drive assembly 6 is fixedly installed above the U-shaped support frame 3. A drive gear 602 is fixedly mounted on the power output shaft 601 of the drive assembly 6, and the drive gear 602 meshes with the gear ring 402 for transmission. A mounting column 7 is fixedly suspended at the bottom of the power output shaft 601. A mounting ring 7 is welded and fitted onto the middle part of the mounting column 7. 01. A drive slip ring 702 is slidably fitted on the part of the mounting column 7 below the mounting ring 701. A T-shaped cleaning component 8 is rotatably connected to the outer circumference of the mounting ring 701. Stainless steel wires are evenly distributed on the outer side of the arc-shaped short support plate of the T-shaped cleaning component 8. A connecting rod 801 is rotatably connected between the long support plate of the T-shaped cleaning component 8 and the drive slip ring 702. A tightening bolt 7021 is threaded through the peripheral wall of the mounting ring 701. The head end of the tightening bolt 7021 is pressed and abutted against the mounting column 7. When the T-shaped cleaning component 8 swings to switch to the horizontal unfolded state and rotates with the mounting column 7, the stainless steel brush filaments on it are in rubbing contact with the outer circumferential threads of the opening and closing screw 202.
[0020] Preferably, a transmission box 5 is welded to the top of the top side crossbeam of the U-shaped support frame 3. The top opening of the transmission box 5 is covered with a box cover, and a circular through hole 501 is provided on the box cover. The opening and closing screw 202 slides through the circular through hole 501.
[0021] Preferably, the drive gear 602 and the gear ring 402 are both located in the transmission box 5, and the bottom of the housing of the drive assembly 6 reducer is fixedly connected to the box cover.
[0022] Implementation 2: This embodiment is based on Implementation 1, but with the following additions: This embodiment includes a gate 2, which is slidably installed in the U-shaped channel 1. A U-shaped guide frame 201 is fixedly connected to the top of the gate 2. Two vertical guide shafts of the U-shaped guide frame 201 are slidably connected to the top side beam of the U-shaped guide frame 201. The bottom end of the opening and closing screw 202 is fixedly connected to the middle position of the top of the gate 2. U-shaped support frames 3 are fixedly installed at the top of the two vertical side walls of the U-shaped channel 1.
[0023] Preferably, the bottom end of the power output shaft 601 is rotatably engaged with the top side beam of the U-shaped support frame 3, and the gear ring 402 and the limiting ring 401 are respectively in contact with the upper and lower sides of the top side beam.
[0024] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: When the drive assembly 6 drives the power output shaft 601 to rotate in both directions, it can drive the gear ring 402 and the threaded sleeve 4 to rotate in both directions through the meshing of the drive gear 602. When the threaded sleeve 4 is driven by the rotation in both directions, it can push the opening and closing screw 202 and the gate 2 to rise and slide, thereby opening and closing the shaped river channel 1. To ensure effective lubrication of the opening and closing screw 202 and the threaded sleeve 4, grease is applied to the outer circumferential threads of the opening and closing screw 202. Since the opening and closing screw 202 is directly exposed, a large amount of particulate impurities (such as small sand particles) will gradually accumulate in the grease after long-term use. These particulate impurities, embedded in the outer circumferential threads of the opening and closing screw 202, will cause jamming and obstruction to the threaded drive of the threaded sleeve 4 and the opening and closing screw 202, thus requiring regular cleaning.
[0025] When the T-shaped cleaning component 8 is rotated to a horizontally unfolded state, its stainless steel bristles rotate with the power output shaft 601 and the mounting post 7, sequentially contacting the outer circumferential threads of the opening / closing screw 202. This cleans and removes the grease and embedded particulate impurities within the threads, restoring the threaded sleeve 4's thread-driven function for the opening / closing screw 202. Thus, the T-shaped cleaning component 8 serves as a brushing and cleaning mechanism for removing grease and embedded particulate impurities. This invention allows for efficient and convenient removal of embedded particulate impurities from grease using this brushing and cleaning mechanism, which is significantly more efficient than... Given the lack of existing brush cleaning mechanisms, this eliminates the tedious step of workers having to repeatedly brush and clean particulate impurities from the outer threads of the opening and closing screw 202 using an external brush, thus reducing the workload of workers. Since the mounting column 7 is fixedly connected to the power output shaft 601, the brush cleaning mechanism can be directly driven by the existing and necessary drive assembly 6 on the door opening and closing device. This allows the brush cleaning mechanism and the opening and closing screw 202 to share the same drive unit in the drive assembly 6 for synchronous driving, eliminating the need to configure an additional drive unit for the brush cleaning mechanism and helping to reduce the cost and power consumption of the opening and closing device to a certain extent.
[0026] A ring of T-shaped cleaning components 8, a ring of connecting rods 801, and a drive slip ring 702 are connected to form a multi-crank rocker mechanism with a circular structure. This mechanism drives the slip ring 702 to slide up and down, causing the ring of T-shaped cleaning components 8 to swing synchronously up and down, switching between expansion and contraction. In the idle state, the ring of T-shaped cleaning components 8 is in a downward-swinging contracted state. In this state, the T-shaped cleaning components 8 are in a vertically swinging position almost parallel to the opening and closing screw 202, and the stainless steel brush bristles on them are connected to the opening and closing screw... The outer peripheral thread of the lever 202 is separated, which prevents the T-shaped cleaning part 8 from not being able to retract when idle. This would cause the stainless steel brush bristles on it to remain in a state of rubbing and cleaning in contact with the outer peripheral thread of the lever 202 for a long time. As a result, even when the lever 202 is not stuck and there is no need to clean the particulate impurities in the grease in its outer peripheral thread, the stainless steel brush bristles will still continue to remove the grease and the particulate impurities in the grease, affecting the effective lubrication of the lever 202 by the grease under normal use.
[0027] The tightening bolt 7021 can tighten the positioning drive slip ring 702, so that the T-shaped cleaning part 8 is kept in a horizontally extended or downward retracted state.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
