Description
Technical Field
[0001] The present application relates to a sluice, and particularly to a gate opening and closing device for a sluice. Background Art
[0002] A sluice is a water-cooled engineering structure used to regulate water level and control flow, and is widely used in shipping, power generation, etc. Generally, a gate chamber needs to be built at a corresponding position, and the gate opening and closing device is installed in the gate chamber to realize the opening and closing of the gate, so as to realize the switching between water retaining and water discharging. The gate opening and closing device generally includes: a gate, a blade water stop installed on the gate, and a power mechanism for controlling the opening and closing of the gate. The movement mode between the gate and the two pier is generally of two types: up and down movement and swing. For the up and down movable gate, generally guide rails are embedded in the two piers so that the gate moves along the guide rails. Correspondingly, the power mechanism generally adopts a winch hoist or a lifting screw module. For the swing gate, generally a main shaft is arranged between the gate and the two piers for rotation. Correspondingly, the power mechanism generally adopts a hydraulic cylinder. The up and down movable gate has a relatively simple structure, but requires a relatively large space in the up and down direction, otherwise it is easy to affect the opening degree and subsequent maintenance and repair. The swing gate has a relatively complex structure, but has small space requirements, is convenient for opening to a large extent, and the blade water stop is easier to complete the sealing of water retaining. Summary of the Invention
[0003] The present application provides a gate opening and closing device for a sluice, combining two methods of movement and swing.
[0004] In the present application, a gate opening and closing device for a sluice is provided, including: Two groups of guide rails, respectively used for being embedded in two opposite piers of the gate chamber; one group of guide rails includes: a first track and a second track. The first track is vertical, the lower part of the second track is vertical, and the distance between the upper part of the second track and the first track gradually increases; A gate, the lower parts of the two vertical side walls are both provided with first guide wheels cooperating with the first track, and the upper parts are both provided with second guide wheels cooperating with the second track; the water retaining surface is on the side far from the second track; Two sections of blade water stops, installed on the water retaining surface of the gate, respectively cooperating with the two piers; A winch hoist, used for being installed on the working bridge of the gate chamber; a steel wire rope is connected to the lower part of the water retaining surface of the gate, driving the gate to switch between the following two states: a vertical closed state: the first guide wheel and the second guide wheel are respectively at the lower parts of the first track and the second track; a horizontal open state: the first guide wheel and the second guide wheel respectively abut against the tops of the first track and the second track; Two groups of locking parts, respectively acting on the two groups of first guide wheels of the gate in the horizontal open state; one group of locking parts includes: a movable arm and a driving mechanism.
[0005] In some embodiments, the lower portions of the first track and the second track coincide; the axes of the first guide wheel and the second guide wheel are vertically aligned; the connection position of the steel wire rope of the hoisting type hoist on the gate is lower than the first guide wheel.
[0006] In some embodiments, the drive mechanism includes: a mounting portion for rotatably connecting the movable arm, a rotating shaft rotatably connected to the mounting portion, and a worm and worm gear transmission pair provided between the rotating shaft and the movable arm.
[0007] In some embodiments, the gate seal includes: a base portion for fixedly connecting to the gate; two sealing portions, the first ends of which are respectively connected to both sides of the base portion, and the second ends are both inclined outward.
[0008] In some embodiments, the upper portion of the first track has a notch for the movable arm to enter / leave the first track.
[0009] In some embodiments, butterfly bolts and nuts for fixing the gate seal and the gate are provided between the gate seal and the gate; the butterfly bolts can be restricted from rotating within the trapezoidal notch formed by the two sealing portions and the base portion.
[0010] In some embodiments, the two sealing portions face the front of the water retaining surface.
[0011] In some embodiments, mounting shafts are fixedly provided at the positions of the gate corresponding to the first guide wheel and the second guide wheel; universal balls for abutting against the inner wall of the guide rail are installed at the outer ends of the mounting shafts.
[0012] In summary, in the present application, a gate opening and closing device for a sluice includes: two groups of guide rails, a gate, two sections of gate seals, a hoisting type hoist, and two groups of locking portions. When the first guide wheel is in the lower portion of the first track and the second guide wheel is in the lower portion of the second track, the gate is in a vertically closed state. Under the action of gravity, the bottom of the gate fits against the gate bottom slab. The hoisting type hoist drives the gate to rise. The first guide wheel keeps moving upward. The second guide wheel first moves upward for a certain distance and then enters the upper portion of the second track and moves along the upper portion of the second track, and the gate starts to tilt. The first guide wheel abuts against the top end of the first track, and the second guide wheel simultaneously abuts against the top end of the second track. At this time, the first guide wheel and the second guide wheel are flush, and the gate changes from vertical to horizontal open state after tilting. The hoisting type hoist mainly acts on the lower portion of the gate to provide an upward pulling force. The inner wall of the inclined section of the second track supports the second guide wheel, and the supporting force has an upward component force in the vertical direction. The two cooperate to enable the gate to stably maintain a horizontal state. The locking portion blocks the first guide wheel to restrict the downward movement of the first guide wheel, so that the gate maintains a horizontal open state, ensuring safety. The beneficial effects are as follows: the opening degree of the gate is larger, the space required in the up and down directions is smaller, the gate can be changed to a horizontal state, and maintenance and repair are more convenient.

[0017] Please refer to Figure 1 and Figure 2 , a gate opening and closing device for a sluice, comprising: two groups of guide rails 1, a gate 2, two sections of gate leaf waterstops 3, a winch hoist 4, and two groups of locking parts 5.
[0018] The gate opening and closing device is installed in the lock chamber. The lock chamber includes: two opposite lock piers 6, a lock floor 7 connecting the bottoms of the two lock piers 6, and a working bridge 8 connecting the tops of the two lock piers 6.
[0019] The two groups of guide rails 1 are respectively embedded in the two lock piers 6, that is, the corresponding outer walls of the lock piers 6 have grooves with corresponding shapes for the guide rails 1 to enter and be installed.
[0020] One group of guide rails 1 includes: a first track 11 and a second track 12. The first track 11 is vertical, the lower part of the second track 12 is vertical, and the distance between the upper part of the second track 12 and the first track 11 gradually increases. More specifically, the lower part of the second track 12 is a vertical section, and the upper part includes an inclined section and an arc section connecting the inclined section and the vertical section.
[0021] Please refer to Figure 2 and Figure 3 , the lower parts of the two vertical side walls of the gate 2 are both provided with first guide wheels 2a that cooperate with the first track 11, and the upper parts are both provided with second guide wheels 2b that cooperate with the second track 12. The front of the gate 2 is a water retaining surface 2c, and the water retaining surface 2c is on the side away from the second track 12. More specifically, the back of the gate 2 has a plurality of horizontal plates and a plurality of vertical plates for reinforcement. A mounting shaft 2d is fixedly connected to two vertical plates close to the vertical side walls. The first guide wheel 2a / second guide wheel 2b is rotatably connected to the outer end of the mounting shaft 2d through a bushing.
[0022] In some embodiments, the lower parts of the first track 11 and the second track 12 are arranged side by side. Correspondingly, the axes of the first guide wheel 2a and the second guide wheel 2b are offset in the up-and-down direction.
[0023] Please refer to Figure 2 、 Figure 6 and Figure 7 When the first guide wheel 2a is at the lower part of the first track 11 and the second guide wheel 2b is at the lower part of the second track 12, the gate 2 is in a vertical state. As the gate 2 rises, the first guide wheel 2a keeps moving upward. The second guide wheel 2b first moves upward for a certain distance and then enters the upper part of the second track 12 and moves along the upper part of the second track 12, and the gate 2 starts to tilt. The first guide wheel 2a abuts against the top of the first track 11, and the second guide wheel 2b abuts against the top of the second track 12 at the same time. At this time, the first guide wheel 2a and the second guide wheel 2b are flush, and the gate 2 changes from vertical to horizontal after tilting.
[0024] Please refer to Figure 4 In some embodiments, universal balls 2e for abutting against the inner wall of the guide rail 1 are installed at the outer ends of the mounting shafts 2d.
[0025] The movement of the gate 2 in the horizontal direction is limited by abutting the inner wall of the guide rail 1 with two universal balls 2e. While the limiting is completed, the first guide wheel 2a / the second guide wheel 2b can move smoothly within the first track 11 / the second track 12.
[0026] Please refer to Figure 1 As shown in, the hoist 4 is installed on the working bridge 8 of the lock chamber. The steel wire rope of the hoist 4 is connected to the lower part of the water retaining surface 2c of the gate 2, driving the gate 2 to switch between the following two states: Vertical closed state: The first guide wheel 2a and the second guide wheel 2b are respectively at the lower parts of the first track 11 and the second track 12. That is, under the action of gravity, the bottom of the gate 2 fits against the lock floor 7.
[0027] Horizontal open state: The first guide wheel 2a and the second guide wheel 2b respectively abut against the tops of the first track 11 and the second track 12. That is, mainly the hoist acts on the lower part of the gate 2 to provide an upward pulling force, and the inner wall of the inclined section of the second track 12 supports the second guide wheel 2b. The supporting force has an upward component in the vertical direction. The two cooperate to enable the gate 2 to stably maintain a horizontal state.
[0028] Please refer to Figure 6 and Figure 7, in some embodiments, the lower parts of the first track 11 and the second track 12 coincide, that is, the first track 11 is connected between the arc segments of the second track 12. Correspondingly, the axes of the first guide wheel 2a and the second guide wheel 2b are aligned vertically and no longer offset. The connection position 4a of the steel wire rope of the hoist 4 on the gate 2 is lower than the first guide wheel 2a.
[0029] Because the connection position 4a of the steel wire rope on the gate 2 is lower than the first guide wheel 2a, when the hoist 4 pulls the gate 2 upward to switch the gate 2 from the vertical closed state to the horizontal open state, the first guide wheel 2a tends to abut against the first inner wall 1a on one side, and the second guide wheel 2b tends to abut against the second inner wall 1b on the opposite side.
[0030] The second guide wheel 2b first comes to the connection between the arc segment and the first track 11. The second guide wheel 2b does not enter the first track 11 but starts to tilt towards the second track 12 and enters the second track 12. Correspondingly, as the gate 2 tilts, the moment generated by the self-weight of the gate 2 will also keep the second guide wheel 2b abutting against the second inner wall 1b and the first guide wheel 2a abutting against the first inner wall 1a.
[0031] The first guide rail 1 then comes to the connection between the arc segment and the first track 11. The second guide wheel 2b does not enter the second track 12 but keeps abutting against the first inner wall 1a and continues to move upward along the first track 11.
[0032] Conversely, when the hoist 4 lowers the gate 2 to switch the gate 2 from the horizontal open state to the vertical closed state, the moment generated by the self-weight of the gate 2 keeps the second guide wheel 2b abutting against the second inner wall 1b and the first guide wheel 2a abutting against the first inner wall 1a.
[0033] Compared with the embodiment where "the lower parts of the first track 11 and the second track 12 are arranged side by side", the coincidence of the lower parts of the first track 11 and the second track 12 makes the structure of the guide rail 1 simpler. The axes of the first guide wheel 2a and the second guide wheel 2b can be aligned vertically, making the force on the gate 2 more balanced and allowing the gate 2 to be designed relatively narrower.
[0034] Please refer to Figure 3 , two sections of the gate leaf water stop 3 are installed on the water-retaining surface 2c of the gate 2. More specifically, the water-retaining surface 2c of the gate 2 has two vertical angle irons 2f, and multiple sets of fasteners are used to install the gate leaf water stop 3 on the angle irons 2f.
[0035] The two sections of the gate leaf water stop 3 cooperate with two gate piers 6 respectively. That is, the bottom of the gate 2 fits against the gate bottom slab 7 under the action of gravity to achieve sealed water retention, and the gate leaf water stop 3 and the gate pier 6 are pressed and fitted to achieve sealed water retention.
[0036] Please refer to Figure 4 In some embodiments, the gate leaf water stop 3 includes: a base 31 and two water stop portions 32. The base 31 is used for fixedly connecting to the gate 2. The first ends of the two water stop portions 32 are respectively connected to both sides of the base 31, and the second ends of the two water stop portions 32 are both inclined outward, that is, a trapezoidal notch 3a is formed between the base 31 and the two water stop portions 32, and the distance between the two water stop portions 32 is larger the farther away from the base 31.
[0037] During the process of the gate leaf water stop 3 being squeezed and fitted to the pier 6, the second end of the water stop portion 32 is in a cylindrical shape and can be deformed, so that the second end of the water stop portion 32 remains in contact with the pier 6, and the design of the two water stop portions 32 also improves the sealing and water blocking effect.
[0038] Please refer to Figure 4 In some embodiments, based on the above embodiment where "the gate leaf water stop 3 includes: a base 31 and two water stop portions 32", the multiple sets of fasteners provided between the gate leaf water stop 3 and the gate 2 are all butterfly bolts 3b and nuts 3c, and the butterfly bolts 3b can be restricted from rotating within the trapezoidal notch 3a.
[0039] Please refer to Figure 5 In some embodiments, based on the above embodiment where "the gate leaf water stop 3 includes: a base 31 and two water stop portions 32", the two water stop portions 32 face the front of the water blocking surface 2c. More specifically, a square tube is fixedly connected to the water blocking surface 2c, and the base 31 is fixedly connected to the vertical surface opposite to the square tube and the water blocking surface 2c. Correspondingly, the pier 6 needs to have an inward protruding portion during construction for the gate leaf water stop 3 to abut against.
[0040] During the process of the gate 2 switching from the horizontal open state to the vertical closed state, through the swing of the gate 2, the gate leaf water stop 3 can better abut against the pier 6, and an extrusion is formed between the two to complete the sealing and water blocking.
[0041] The installation, disassembly, and replacement between the gate leaf water stop 3 and the gate 2 are simpler and more convenient.
[0042] Please refer to Figure 7 and Figure 8 Two sets of locking portions 5 respectively act on two sets of first guide wheels 2a of the gate 2 in the horizontal open state. One set of locking portion 5 includes: a movable arm 51 and a driving mechanism 52. More specifically, the locking portion 5 is installed on the pier 6 or the guide rail 1, and the movable arm 51 is driven to move through the driving mechanism 52 to switch the state; when the movable arm 51 is in the non-working state, it will not interfere with the movement of the first guide wheel 2a in the first track 11 and the second guide wheel 2b in the second track 12; when the movable arm 51 is in the working state, it blocks the first guide wheel 2a and restricts the first guide wheel 2a from moving downward, so that the gate 2 remains in the horizontal open state to ensure safety.
[0043] Please refer toFigure 8 and Figure 9 , in some embodiments, the driving mechanism 52 includes: a mounting portion 521 for rotatably connecting the movable arm 51, a rotating shaft 522 rotatably connected to the mounting portion 521, and a worm and worm gear transmission pair 523 disposed between the rotating shaft 522 and the movable arm 51. More specifically, the rotating shaft 522 enters the working bridge 8 upward, facilitating the operation of the rotating shaft 522 on the working bridge 8.
[0044] Please refer to Figure 6 , in some embodiments, based on the above embodiment of "the lower portions of the first track 11 and the second track 12 coincide", since the second guide wheel 2b remains in contact with the second inner wall 1b and the first guide wheel 2a remains in contact with the first inner wall 1a when the gate 2 switches between the vertical closed state and the horizontal open state, the upper portion of the first track 11 may have a notch 11a for the movable arm 51 to enter / leave the first track 11. Correspondingly, the upper portion of the second track 12 is not designed with a notch. When the movable arm 51 moves to contact the outer wall of the second track 12, the movable arm 51 reaches the non-operating state.
