Description

Technical Field

[0001] This invention relates to a landscape water feature device on a flap gate. It is applicable to the field of water conservancy engineering technology. Background Technology

[0002] In urban water conservancy projects, flap gates are often used, with the gates and piers almost completely submerged in water. Therefore, fountains, misting systems, and lighting can be installed on the gates to create water features. When the gate is fully open, silt accumulates in front of it, clogging the nozzles and preventing the water features from operating. Therefore, protecting the misting nozzles on the flap gate is crucial. Currently, a common solution is to place the water features inside the flap gate, with covers over the nozzles' spray channels. When the flap gate rotates to the bottom of the river, the covers close to prevent silt from entering and clogging the nozzles. The covers need to close when the flap gate is at the bottom and open when it's above the water. However, for gates that operate continuously in the water, ordinary hydraulic or electric control cover mechanisms often suffer from drawbacks such as difficult wiring and piping, susceptibility to damage, and difficulty in replacement and maintenance. Choosing the right cover type and figuring out how to handle the sludge at the nozzle outlet became a major challenge for design engineers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: In order to solve the above-mentioned technical problem, the present invention provides a landscape water show device on a flap gate that is not prone to clogging of the water show nozzles.

[0004] The technical solution adopted in this invention is: a landscape water feature device on a flap gate, characterized in that: a cavity is provided inside the flap gate, a channel leading to the cavity is provided on the top surface of the gate body, water feature nozzles are arranged inside the cavity, and a lifting mechanism for lifting the water feature nozzles through the channel to the outside of the flap gate is installed inside the cavity. The lifting mechanism is mounted on a mounting plate inside the cavity, and a mounting seat is installed at the end of the lifting mechanism. The water feature nozzle is mounted on the mounting seat, and an anti-clogging structure for preventing silt from clogging the water feature nozzles when the flap gate is opened due to them being underwater. Thus, when the gate needs to be closed, the flap gate is rotated to the bottom of the river. During this process, the lifting mechanism transports the water feature nozzles into the gate body, protecting them, while the anti-clogging structure encloses the water feature nozzles inside the gate body to prevent the nozzles from being clogged by silt from the bottom of the river.

[0005] A movable cover plate is provided at the position of the flap gate channel. The movable cover plate is rotatably connected to the gate body through a hinge structure. The movable cover plate is connected to the lifting mechanism through a linkage mechanism.

[0006] The linkage mechanism includes a traction spring, a slide rail, a slider, and a connecting rod. The slide rail is arranged on the inner wall of the cavity along the direction of the water jet nozzles. The slider is slidably mounted on the slide rail. One end of the traction spring is rotatably connected to the movable cover plate, and the other end is rotatably connected to the slider. The connecting rod is mounted on the slider and can move along the slide rail with the slider. Thus, when the flap gate needs to be closed, the flap gate is controlled to rotate. During the rotation, the movable cover plate rotates along the hinge structure under its own weight and the counterweight. Initially, the slider on the inner wall of the gate moves upward on the slide rail under the action of the return spring. At this time, the switch on the control circuit is disconnected, allowing the water jet nozzles to retract into the gate body through the channel, driven by the lifting mechanism. When the flap gate rotates to the bottom of the river channel, the movable cover plate rotates to the position of closing the channel. When the flap gate opens, it rotates to the water surface. During this rotation, the movable cover plate rotates along the hinge structure under its own weight and the counterweight. When the flap gate reaches the top position, the passage opens. At this time, the slider on the slide rail on the inner wall of the gate moves to the bottom position. The connecting rod installed on the slider then moves to the contact position with the switch, allowing the lifting mechanism to lift the water jet nozzle through the passage to the outside of the gate.

[0007] The lifting mechanism includes a telescopic cylinder installed inside the gate body. The fixed end of the telescopic cylinder is installed inside the cavity, and a water jet nozzle is installed on the telescopic end of the cylinder. The telescopic cylinder is connected to a two-way solenoid valve, which is connected to a control circuit. A switch is connected in series with the two-way solenoid valve in the control circuit, and the switch is connected to the movable cover plate through a linkage mechanism. Thus, when the gate is opened, the linkage mechanism connected to the movable cover plate activates the control circuit, and the two-way solenoid valve is activated. At this time, the telescopic cylinder extends and drives the water jet nozzle to extend outside the gate body. During the closing process of the gate, the linkage mechanism disengages from the switch, the control circuit is disconnected, the two-way solenoid valve is also disconnected, and the telescopic cylinder retracts, driving the water jet nozzle back into the gate body.

[0008] A counterweight is fixedly installed on the movable cover plate. When the flap gate is opened, the hinge structure on the movable cover plate is located above the counterweight on the movable cover plate.

[0009] A limit plate is installed on the gate body at the passage position, and rubber shock-absorbing pads are installed on the limit plate. In this way, during the rotation of the flap gate, the limit plate will limit the movement of the movable cover plate, and the rubber shock-absorbing pads will dampen the contact between the limit plate and the movable cover plate.

[0010] The anti-sprinkler clogging structure has a sprinkler protective cover arranged outside the water shower nozzle. When the flap gate rotates to the river surface, the sprinkler protective cover is opened by the protective cover opening and closing mechanism. When the flap gate starts to rotate towards the river bottom, the sprinkler protective cover is closed by the protective cover opening and closing mechanism.

[0011] The nozzle protective cover has baffles arranged around the outside of the water jet nozzle. The opening and closing mechanism of the protective cover has rotating plates installed on the top of each baffle. Each rotating plate is connected to the baffle by a hinge. The rotating plates installed on the baffles can rotate toward the water jet nozzle. When the rotating plates rotate toward the water jet nozzle, each rotating plate cooperates to close the nozzle protective cover. A tension spring is connected between the rotating plate and the baffle facing the water jet nozzle. A traction rope for rotating the rotating plate toward the baffle is connected to each rotating plate. One end of each traction rope is fixed to each rotating plate, and the other end of each traction rope passes through the mounting plate. The end of the traction rope passing through the mounting plate is connected to the baffle. Thus, when the flap gate rotates to the river surface and the lifting mechanism lifts the nozzle protection cover and water show nozzle to near the top, the baffle connected to the end of the traction rope moves to the position of contact with the mounting plate. At this time, as the nozzle protection cover continues to move, the traction rope will pull the rotating plate to rotate on each baffle, thereby opening the nozzle protection cover. Before the flap gate rotates to the river bottom, the lifting mechanism retracts the nozzle protection cover and water show nozzle. During the retraction of the nozzle protection cover, the baffle at the end of the traction rope no longer contacts the mounting plate, and the traction rope no longer pulls the rotating plate. The rotating plate installed on each baffle rotates towards the water show nozzle under the action of the tension spring, ultimately closing the nozzle protection cover and preventing silt from the river channel from entering the nozzle protection cover.

[0012] Each baffle plate is equipped with a stop block to limit the rotation range of the rotating plate. In this way, when the rotating plate on the baffle plate rotates towards the water jet nozzle, the stop block limits the rotation of each rotating plate, preventing large gaps between the rotating plates caused by different rotation amounts.

[0013] The beneficial effects of this invention are as follows: This invention provides a channel leading into the gate body on the top surface of the flap gate body, and a reversible movable cover plate at the channel position on the gate body. This allows the movable cover plate to cover and close the channel when the flap gate is closed and rotated to the bottom of the river channel. When the flap gate is opened and rotated to the top position, the movable cover plate will move away from the channel under gravity and open the channel. This invention also includes a lifting mechanism connected to the movable cover plate within the flap gate body via a linkage mechanism. This mechanism retracts the water jet nozzles into the gate body when the flap gate is closed and the movable cover plate closes the channel, and extends the water jet nozzles out of the gate body when the flap gate is opened and the movable cover plate opens the channel. This invention features a nozzle protective cover around the water feature nozzle, and an opening and closing mechanism for the cover. When the flap gate rotates to the water surface and the lifting mechanism raises the nozzle protective cover and the water feature nozzle to a certain height, the traction rope pulls the rotating plate towards the nozzle protective cover, thus opening it. When the flap gate begins to rotate towards the riverbed and the lifting mechanism begins to move the nozzle protective cover and the water feature nozzle into the gate body, the traction rope no longer pulls the rotating plate. Under the reset action of the tension spring, the rotating plate rotates towards the water feature nozzle, thus closing the nozzle protective cover and preventing silt from the riverbed from entering the nozzle protective cover and affecting the water feature nozzle.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] This embodiment describes a landscape water feature device on a flap gate. It is used to prevent the water feature nozzles 7 from being blocked by silt in the river when the flap gate is closed and rotated to the bottom of the river channel.

[0021] In this embodiment, a channel leading to the inner cavity of the gate body 14 is provided on the top surface of the gate body 14, and a water jet nozzle 7 is installed inside the cavity of the gate body 14. The top surface in this embodiment is the top surface of the gate body 14 when the gate is open and rotated to the river surface.

[0022] In this embodiment, a movable cover plate 4 is rotatably installed on the top surface of the gate body 14 at the channel position via a hinge structure 1. A counterweight 3 is provided on the movable cover plate 4 at a position away from the hinge structure 1. When the flap gate is closed and rotated to the bottom of the river channel, the counterweight 3 on the movable cover plate 4 is located below the hinge structure 1. When the flap gate is closed, it rotates to the bottom of the river channel, at which point the top surface of the gate body 14 rotates to a vertical position, while the movable cover plate 4 remains vertical under its own weight and the gravity of the counterweight 3. The movable cover plate 4 covers the channel of the gate body 14, thus closing the channel. To prevent collision between the movable cover plate 4 and the gate body 14 when the channel is closed, a limiting plate 6 is provided on the gate body 14, and a rubber shock-absorbing pad 4 is provided on the limiting plate 6. When the flap gate is opened, it rotates to the river surface. At this time, the top surface of the gate body 14 rotates to a horizontal position, while the movable cover plate 4 remains vertical under its own weight and the gravity of the counterweight block 3, and the passage is opened.

[0023] In this embodiment, a movable beam 2 is fixedly installed on the movable cover plate 4, and the hinge structure 1 is installed on the movable beam 2. The movable beam 2 serves to strengthen the movable cover plate 4.

[0024] In this embodiment, a lifting mechanism 13 is provided inside the cavity of the gate body 14. The lifting mechanism 13 in this embodiment is a telescopic cylinder. The fixed end of the telescopic cylinder is fixedly mounted on the mounting plate 15 inside the cavity. A mounting base 16 is mounted on the telescopic end of the telescopic cylinder, and a water jet nozzle 7 is mounted on the mounting base 16. A two-way solenoid valve is connected to the telescopic cylinder. The two-way solenoid valve is connected to a control circuit, and a switch is connected in series with the solenoid valve in the control circuit.

[0025] In this embodiment, a slide rail 9 is fixedly installed on the inner wall of the gate body 14 along the direction of the water jet nozzle 7, and a slider 11 is slidably installed on the slide rail 9. A traction spring 10 and a connecting rod 12 are respectively installed on the slider 11. One end of the traction spring 10 is rotatably connected to the counterweight 3, and the other end of the traction spring 10 is rotatably connected to the slider 11. When the flap gate rotates to the water surface, the movable baffle 21 rotates in the opposite direction relative to the gate body 14. At this time, the slider 11 moves towards the bottom of the slide rail 9 under the action of gravity, and the traction spring 10 is stretched. When the slider 11 moves to the bottom position of the slide rail 9, the connecting rod 12 installed on the slider 11 will touch the switch, causing the switch to close. At this time, the telescopic cylinder will extend and drive the mounting base 16 and the water jet nozzle 7 installed on the mounting base 16 to extend outside the gate body 14, and the channel opens synchronously. As the flap gate closes and rotates towards the bottom of the river channel, the movable baffle 21 rotates in the opposite direction relative to the gate body 14. At this time, the slider 11 moves towards the top of the slide rail 9 under the reset action of the traction spring 10. When the slider 11 begins to move, the connecting rod 12 installed on the slider 11 will disengage from the switch, causing the switch to open. At this time, under the action of the two-way solenoid valve, the telescopic cylinder will retract and drive the water jet nozzle 7 to retract into the gate body 14, at which point the channel closes synchronously.

[0026] In this embodiment, a nozzle protective cover 8 is fitted over the water spray nozzle 7. The nozzle protective cover 8 is opened by the protective cover opening and closing mechanism when the flap gate rotates to the river surface and the lifting mechanism lifts the mounting base 16 to a certain height, and is closed by the protective cover opening and closing mechanism when the flap gate begins to rotate towards the river bottom and the lifting mechanism drives the mounting base 16 to retract to a certain height.

[0027] In this embodiment, the nozzle protective cover 8 has baffles arranged around the outside of the water jet nozzle 7, and adjacent baffles are connected to each other. The opening and closing mechanism of the protective cover has rotating plates 17 arranged on each baffle, and each rotating plate 17 is connected to the baffle by a hinge, so that the rotating plate 17 on each baffle can rotate toward the water jet nozzle. Each rotating plate 17 and the baffle is connected to a tension spring 18 on the side facing the water jet nozzle, and a stop block 19 for limiting the rotation of the rotating plate 17 is installed on the side of each baffle facing the water jet nozzle. A traction rope 20 for rotating the rotating plate 17 toward the baffle is also installed on each rotating plate 17, one end of each traction rope 20 is connected to each rotating plate 17, and the other end of each traction rope 20 passes through a mounting plate 15. A baffle 21 is connected to the end of the traction rope 20 that passes through the mounting plate 15. When the flap gate rotates to the river surface, the lifting mechanism lifts the nozzle protective cover and water show nozzle to a certain height. Then, the baffle 21 at the end of the traction rope 20 moves to a position contacting the mounting plate 15. At this time, as the lifting mechanism continues to lift the nozzle protective cover and water show nozzle, the traction rope 20 is tightened, pulling the rotating plate 17 towards the baffle. The nozzle protective cover 8 opens, and the tension spring 18 connecting the rotating plate 17 and the baffle is stretched. When the flap gate begins to rotate towards the riverbed, the lifting mechanism retracts the nozzle protective cover and water show nozzle. During this retraction, the baffle 21 at the end of the traction rope 20 no longer contacts the mounting plate 15, and the traction rope 20 no longer pulls the rotating plate 17. At this time, the rotating plate 17 rotates towards the water show nozzle under the reset action of the tension spring 18. At this time, the rotating plate 17 is stopped by the stop 19 during rotation, so that each rotating plate 17 rotates to the same plane, avoiding excessive rotation of the rotating plate 17 and causing a gap between the two rotating plates 17.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
