TECHNICAL FIELD

[0001] The utility model relates to the technical field of gate, especially a adjustable gate structure for water conservancy project. BACKGROUND

[0002] The gate is a device for controlling water flow, raising or lowering water level, and is an important part of hydraulic structures, widely used in water conservancy projects, rivers, lakes, channels and various hydraulic structures. In the process of controlling water flow by using the gate, a height-adjustable gate is usually used to change the opening degree of the gate to achieve the effect of regulating water flow.

[0003] According to the search, the patent "Lifting gate structure for water conservancy project" authorized announcement "CNU" drives the transmission shaft to rotate through the motor, drives the lead screw to rotate under the action of the first bevel gear and the second bevel gear, drives the sleeve to move up and down with the sliding plate fixedly connected with the sleeve, the sliding plate is arranged in the sliding groove, the sliding plate is fixedly connected with the gate, so as to realize the sliding of the gate in the sliding groove in the door frame, and achieve the effect of adjusting water level and controlling water flow by lifting the gate.

[0004] Although the height of the gate can be adjusted in the above-mentioned application, the lead screw is exposed in water and natural environment for a long time, which can easily cause rust on the surface of the lead screw, thereby affecting the stability of the connection between the lead screw and the sleeve when rotating, and leading to poor stability when the lead screw drives the gate to move up and down.

[0005] Therefore, a adjustable gate structure for water conservancy project is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at solving the above-mentioned problems and provides a adjustable gate structure for water conservancy project, which improves the problem that the lead screw in the above-mentioned application is exposed in water and natural environment for a long time, which can easily cause rust on the surface of the lead screw, thereby affecting the stability of the connection between the lead screw and the sleeve when rotating, and leading to poor stability when the lead screw drives the gate to move up and down.

[0007] The utility model realizes the above-mentioned purpose through the following technical scheme, a adjustable gate structure for water conservancy project, including: fixed frame, the inner wall sliding connection of fixed frame has the gate leaf, the top of fixed frame is fixedly connected with motor, the output shaft of motor penetrates fixed frame and is fixedly connected with lead screw, the surface of lead screw is connected with circular ring, the top of gate leaf is fixedly connected with the surface of circular ring, the surface of lead screw is provided with protection mechanism;

[0008] The protective mechanism includes a mounting plate fixedly connected to one side of the fixed frame. Corrugated sleeves are fixedly connected between the bottom end of the ring and the top end of the mounting plate, and between the top end of the ring and the inner top wall of the fixed frame. An annular tube is fixedly connected to the top end of the ring, and multiple circular tubes are connected to the surface of the annular tube. A cylinder is fixedly connected to the top end of the fixed frame, and the cylinder is filled with lubricating oil. An outlet pipe is connected between the cylinder and the annular tube.

[0009] Preferably, the protective mechanism further includes two gears meshing together. The inner wall of one gear is fixedly connected to the output shaft of the motor, and a cam is fixedly connected to the surface of the other gear. A piston plate is slidably connected to the inner wall of the cylinder. A pressing rod is fixedly connected to one end of the piston plate, and the other end of the pressing rod extends through the cylinder and fits against the surface of the cam. A spring is fixedly connected between one end of the piston plate and the inner wall of the cylinder. Under the action of the two gears, the cam intermittently pushes the pressing rod, thereby causing the piston plate to intermittently press the lubricating oil inside the cylinder. This allows the lubricating oil to enter the annular pipe and flow through the pipe to the gap between the annulus and the lead screw, ensuring that the lead screw remains lubricated at the connection point with the annulus during rotation.

[0010] Preferably, a storage cylinder is fixedly connected to the top of the fixed frame, and an inlet pipe connects the bottom of the storage cylinder to the cylinder. This helps to ensure that the space between the other end of the piston plate and the inner wall of the cylinder is always fully filled with lubricating oil.

[0011] Preferably, both the surface of the inlet pipe and the surface of the outlet pipe are equipped with one-way valves. This helps ensure the stability of the protective mechanism during operation.

[0012] Preferably, the upper end of the inner wall of the ring forms an angle with the vertical plane, and the inclination angle of the circular tube is the same as the inclination angle of the upper end of the inner wall of the ring. This facilitates better flow of lubricating oil to the gap between the ring and the lead screw.

[0013] Preferably, the middle part of the outlet pipe is corrugated. This ensures the stability of the connection between the annular pipe and the outlet pipe when the annulus moves.

[0014] Preferably, a protective frame is fixedly connected to the top of the fixed frame, and a cover plate is provided at the top of the protective frame. This helps to improve the protective effect on the device.

[0015] The beneficial effects of this utility model are:

[0016] 1. The above-mentioned protective mechanism uses two corrugated sleeves to protect the surface of the lead screw, preventing the lead screw from being exposed to the outside for a long time and causing corrosion. This helps to improve the stability of the connection between the lead screw and the ring during long-term use. When adjusting the opening of the gate, the action of the two gears helps to make the cam intermittently push the extrusion rod, thereby causing the piston plate to intermittently extrude the lubricating oil in the cylinder. This allows the lubricating oil to enter the annular pipe and flow through the pipe to the gap between the ring and the lead screw. This helps to keep the connection between the lead screw and the ring lubricated at all times during rotation, thereby improving the stability of the lead screw driving the gate to move up and down through the ring.

[0017] 2. After the piston plate releases the pressure on the lubricating oil in the cylinder, the storage cylinder and the inlet pipe facilitate the automatic addition of lubricating oil into the cylinder, which helps to keep the space between the other end of the piston plate and the inner wall of the cylinder fully filled with lubricating oil.

Detailed Implementation

[0024] The technical solutions of the present 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figures 1-5As shown, an adjustable gate structure for water conservancy projects includes: a fixed frame 1, a gate plate 2 slidably connected to the inner wall of the fixed frame 1, a motor 3 fixedly connected to the top of the fixed frame 1, the output shaft of the motor 3 passing through the fixed frame 1 and fixedly connected to a lead screw 4, a ring 5 threadedly connected to the surface of the lead screw 4, the top of the gate plate 2 fixedly connected to the surface of the ring 5, and a protective mechanism 6 provided on the surface of the lead screw 4; wherein, the protective mechanism 6 includes an mounting plate 61 fixedly connected to one side of the fixed frame 1, corrugated sleeves 62 fixedly connected between the bottom end of the ring 5 and the top end of the mounting plate 61 and between the top end of the ring 5 and the inner top wall of the fixed frame 1, an annular tube 63 fixedly connected to the top end of the ring 5, multiple circular tubes 64 communicating with the surface of the annular tube 63, a cylinder 65 fixedly connected to the top end of the fixed frame 1, the cylinder 65 being filled with lubricating oil, and an outlet pipe 66 communicating between the cylinder 65 and the annular tube 63. The bottom end of the lead screw 4 is rotatably connected to the top end of the mounting plate 61, and the annular tube 63 is disposed inside the corrugated sleeve 62.

[0026] When adjusting the opening of the gate 2 using this device, the motor 3 is started by the controller. The output shaft of the motor 3 drives the lead screw 4 to rotate, thereby causing the ring 5 to move the gate 2.

[0027] The corrugated sleeve 62 is a rubber component and has corrosion-resistant properties. During use, the corrugated sleeve 62 protects the surface of the lead screw 4. When the ring 5 moves, it will cause the corresponding corrugated sleeve 62 to contract or expand.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the protective mechanism 6 also includes two gears 67 meshing together. The inner wall of one gear 67 is fixedly connected to the output shaft of the motor 3, and a cam 68 is fixedly connected to the surface of the other gear 67. A piston plate 69 is slidably connected to the inner wall of the cylinder 65. A pressing rod 610 is fixedly connected to one end of the piston plate 69, and the other end of the pressing rod 610 passes through the cylinder 65 and fits against the surface of the cam 68. A spring 611 is fixedly connected between one end of the piston plate 69 and the inner wall of the cylinder 65. A storage cylinder 612 is fixedly connected to the top of the fixed frame 1, and an inlet pipe 613 connects the bottom end of the storage cylinder 612 to the cylinder 65.

[0029] The top of the storage cylinder 612 is provided with a feed inlet and a sealing plug, through which lubricating oil can be periodically added to the storage cylinder 612.

[0030] In the initial state of the device, when the other end of the extrusion rod 610 is in contact with the surface of the cam 68, the space between the other end of the piston plate 69 and the inner wall of the cylinder 65 is fully filled with lubricating oil.

[0031] When the starting motor 3 moves the gate plate 2 through the ring 5, the output shaft of the motor 3 drives one of the gears 67 to rotate, which in turn drives the other gear 67 to rotate the cam 68 synchronously. When the cam 68 rotates from the lowest point to the highest point and contacts the other end of the extrusion rod 610, the extrusion rod 610 pushes the piston plate 69 to extrude the lubricating oil in the cylinder 65, so that the lubricating oil enters the outlet pipe 66 and flows out through the annular pipe 63 and then through multiple circular pipes 64. At this time, the lubricating oil flows to the gap between the ring 5 and the lead screw 4. When the cam 68 rotates from the highest point to the lowest point and contacts the other end of the extrusion rod 610, the piston plate 69 and the extrusion rod 610 are reset under the action of the spring 611. At this time, the lubricating oil in the storage cylinder 612 enters the cylinder 65 through the inlet pipe 613, so that the space between the other end of the piston plate 69 and the inner wall of the cylinder 65 is always fully filled with lubricating oil.

[0032] like Figure 4 As shown, a one-way valve 614 is provided on the surface of both the inlet pipe 613 and the outlet pipe 66.

[0033] Under the action of the one-way valve 614, the liquid in the inlet pipe 613 and outlet pipe 66 can only flow in one direction. When the piston plate 69 squeezes the lubricating oil in the cylinder 65, the lubricating oil enters the outlet pipe 66 and cannot enter the inlet pipe 613. When the piston plate 69 moves in the opposite direction, the lubricating oil in the storage cylinder 612 will enter the cylinder 65 through the inlet pipe 613, and the lubricating oil in the outlet pipe 66 cannot flow back.

[0034] like Figure 5 As shown, the upper end of the inner wall of the ring 5 forms an angle with the vertical plane, and the inclination angle of the circular tube 64 is the same as the inclination angle of the upper end of the inner wall of the ring 5.

[0035] When the lubricating oil flows out through the circular pipe 64, it flows through the inclined surface at the upper end of the inner wall of the circular ring 5 to the connection between the circular ring 5 and the lead screw 4. Under the action of the rotation of the lead screw 4, the lubricating oil is evenly distributed on the surface of the lead screw 4.

[0036] like Figure 5 As shown, the middle part of the outlet pipe 66 is set as a corrugated pipe. When the ring 5 moves up and down, the corrugated part will be stretched or contracted synchronously.

[0037] like Figure 1 and Figure 2 As shown, a protective frame 7 is fixedly connected to the top of the fixed frame 1, and a cover plate is provided at the top of the protective frame 7. The motor 3, gear 67, storage cylinder 612, and cylinder 65 are all located inside the protective frame 7, and the cover plate can be installed with the protective frame 7 by bolts. Lubricating oil can be introduced into the storage cylinder 612 by opening the cover plate.

[0038] In use, the two corrugated sleeves 62 protect the surface of the lead screw 4. When adjusting the opening of the gate 2, the controller starts the motor 3. The output shaft of the motor 3 drives the lead screw 4 to rotate, thereby causing the ring 5 to move the gate 2 and causing the corresponding corrugated sleeves 62 to contract or extend. At the same time, the output shaft of the motor 3 will drive the cam 68 to rotate synchronously under the action of the two gears 67. When the cam 68 rotates from the lowest point to the highest point and contacts the other end of the extrusion rod 610, the extrusion rod 610 will push the piston plate 69 to extrude the lubricating oil in the cylinder 65, so that the lubricating oil enters the annular pipe 63 through the outlet pipe 66 and exits from multiple As the lubricating oil flows out of the circular tube 64, it flows through the inclined surface at the upper end of the inner wall of the circular ring 5 to the connection between the circular ring 5 and the lead screw 4. Under the action of the rotation of the lead screw 4, the lubricating oil is evenly distributed on the surface of the lead screw 4, making the connection between the lead screw 4 and the circular ring 5 more stable during rotation. When the cam 68 rotates from the highest point to the lowest point and contacts the other end of the extrusion rod 610, the piston plate 69 and the extrusion rod 610 are reset under the action of the spring 611. At this time, the lubricating oil in the storage cylinder 612 enters the cylinder 65 through the liquid inlet pipe 613, so that the space between the other end of the piston plate 69 and the inner wall of the cylinder 65 is always fully filled with lubricating oil.

[0039] It should be noted that the motor 3 and check valve 614 mentioned above are devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 3 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
