Description

Technical Field

[0001] This utility model relates to the field of hydraulic structures technology, specifically a quick-installation dam gate. Background Technology

[0002] Dam gates are control facilities installed in water conservancy projects such as dams, rivers, and reservoirs. They achieve precise control of water flow through opening and closing operations and are mainly used for water storage and power generation, irrigation and water supply, flood discharge and drainage, or to create artificial landscapes. They can effectively improve the efficiency of water resource management.

[0003] When existing dam gates are installed in the ditch where the dam is located, a concrete structure with a slot is usually poured in advance at a designated location in the ditch. The gate is then installed into the slot by hoisting. Since the width of the slot is larger than the thickness of the existing gate, the gate is prone to swaying in the slot when it slides down the slot. This makes it difficult for the gate to connect with the embedded fasteners in the ditch, making the gate installation process troublesome and time-consuming. In addition, during the opening and closing of the gate leaf on the existing dam gate, the lack of a corresponding reinforcement structure between the gate leaf and the embedded fasteners makes the gate leaf susceptible to the impact of water flow and difficult to maintain a vertical position, thus affecting the normal opening and closing of the gate. Utility Model Content

[0004] The purpose of this invention is to provide a quick-installation dam gate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation dam gate, comprising a U-shaped frame, a top box at the center of the top of the U-shaped frame, a forward and reverse motor mounted on one side of the top of the top box, a rotating shaft at the output end of the forward and reverse motor, a spur gear at the center of the rotating shaft, an external gear ring meshing with the outer wall of the spur gear, an internally threaded cylinder fixedly connected to the inner side of the external gear ring, a screw thread passing through the center of the internally threaded cylinder, a gate leaf fixedly connected to the bottom end of the screw, sliding strips fixedly connected to the inner walls of both sides of the U-shaped frame, a crossbeam at the center of the U-shaped frame, an opening at the center of the crossbeam, a fixed base at the bottom of the U-shaped frame, side plates fixedly connected to both sides of the top of the fixed base, a connecting rod on one side of each of the two side plates, and a sealing strip fixedly connected to the bottom end of the gate leaf.

[0006] Preferably, the top of the top box has a through hole, and the screw is movably connected to the top box through the through hole.

[0007] Preferably, the internally threaded rotary drum is rotatably connected to the U-shaped frame via an external gear ring, and the screw is movably inserted and connected to the U-shaped frame via the internally threaded rotary drum.

[0008] Preferably, the door leaf is slidably connected to the slide bar via a screw, and the door leaf is movably connected to the crossbeam via an opening.

[0009] Preferably, both sides of the U-shaped frame are provided with sliding grooves, which are slidably connected to the side plates, and the U-shaped frame is slidably connected to the side plates through the sliding grooves.

[0010] Preferably, the bottom of the U-shaped frame is provided with insertion holes on both sides, the connecting rod is fixedly connected to the embedded base, the connecting rod is engaged with the U-shaped frame through the insertion holes, and the U-shaped frame is engaged with the embedded base through the connecting rod and the side plate.

[0011] Preferably, multiple reinforcing bars are fixedly connected to the other side wall of the side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This quick-installation dam gate, through its embedded base, side plates, reinforcing bars, and connecting rods, allows for positioning and connection with the pre-embedded base, side plates, and connecting rods within the concrete structure during hoisting. This enables the sliding grooves on both sides of the gate to slide stably along the side plates, and allows the U-shaped frame on the gate to smoothly connect with the connecting rods on the embedded base. This facilitates the connection between the gate and the embedded components in the ditch, enabling quick installation of the gate.

[0014] This quick-installation dam gate, through the setting of sliding strips, crossbeams and openings, allows the gate leaf to slide up and down along the opening on the crossbeam when it is opened and closed by the drive mechanism. This ensures that the front and back of the gate leaf are supported by the crossbeam during the opening and closing process, while the side walls of the gate leaf are limited by the sliding strips. This helps the gate leaf maintain a vertical state during opening and closing, thereby reducing the adverse effects of water flow on the opening and closing of the gate leaf.

[0023] like Figures 1 to 4As shown, the quick-installation dam gate in this embodiment includes a U-shaped frame 1. The function of the U-shaped frame 1 is to support the gate leaf 6 when the gate is opened, thereby facilitating the subsequent closing of the gate leaf 6. A top box 2 is provided at the middle of the top of the U-shaped frame 1. The front of the top box 2 is also provided with an inspection port for easy inspection and maintenance of the components inside the top box 2. A forward and reverse motor 4 is installed on one side of the top of the top box 2. The forward and reverse motor 4 is controlled by a microcontroller, so that the forward and reverse motor 4 drives the spur gear 12 by rotating in the forward or reverse direction, thereby enabling the spur gear 12 to drive the external gear ring 11. The rotation of the internal threaded drum 10 is more conducive to the rotation of the external gear ring 11. The output end of the forward and reverse motor 4 is provided with a rotating shaft 13. A spur gear 12 is provided in the middle of the rotating shaft 13. The outer side of the spur gear 12 is meshed with the external gear ring 11. The inner side of the external gear ring 11 is fixedly connected to the internal threaded drum 10. The internal threaded drum 10 is located inside the top box 2 and can be protected by the top box 2. The movable thread of the internal threaded drum 10 is threaded through the middle of the screw rod 3. The screw rod 3 will slide up or down along the U-shaped frame 1 under the drive of the internal threaded drum 10, so that the door leaf 6 can move up or down. The screw 3 moves downwards, thereby opening and closing the door leaf 6. The bottom end of the screw 3 is fixedly connected to the door leaf 6. A reinforcing beam is provided on the back surface of the door leaf 6 to increase its stability. Sliding strips 17 are fixedly connected to the inner walls of both sides of the U-shaped frame 1. The function of the sliding strips 17 is to allow the door leaf 6 to slide up and down vertically along the U-shaped frame 1. A crossbeam 14 is provided in the middle of the U-shaped frame 1. The function of the crossbeam 14 is to support the front and back of the door leaf 6, which is more conducive to maintaining the stability of the door leaf 6 when opening and closing. An opening 19 is provided in the middle of the crossbeam 14. The width of the opening 19 is... The thickness of the gate leaf 6 is matched with the thickness of the gate leaf 6 so that the gate leaf 6 can maintain contact with the crossbeam 14. The bottom of the U-shaped frame 1 is provided with a fixed base 9, which is pre-buried at the gate installation point. The top two sides of the fixed base 9 are fixedly connected with side plates 7, which are also fixed fasteners and are connected to the precast concrete structure on the dam. One side of each of the two side plates 7 is provided with a connecting rod 15. The connecting rod 15 is used to reinforce the U-shaped frame 1 on the fixed base 9, thereby improving the connection strength between the bottom of the U-shaped frame 1 and the fixed base 9. The bottom end of the gate leaf 6 is fixedly connected with a sealing strip 16.

[0024] Specifically, the top of the top box 2 has a through hole, and the screw 3 is movably connected to the top box 2 through the through hole, so that the screw 3 can pass through the top of the top box 2 and the top of the U-shaped frame 1 under the action of the internal threaded rotating cylinder 10, thereby facilitating the screw 3 to drive the door leaf 6, and thus enabling the door leaf 6 to open and close smoothly.

[0025] Furthermore, the internal threaded drum 10 is rotatably connected to the U-shaped frame 1 via the external gear ring 11, and the screw 3 is movably inserted and connected to the U-shaped frame 1 via the internal threaded drum 10. The threads on the internal threaded drum 10 and the screw 3 mesh with each other, so that the screw 3 moves linearly through the internal threaded drum 10, thereby realizing the lifting and lowering of the screw 3 on the U-shaped frame 1.

[0026] Furthermore, the door leaf 6 is slidably connected to the slide bar 17 via the screw 3, and the door leaf 6 is movably connected to the crossbeam 14 via the opening 19. Under the action of the slide bar 17 and the crossbeam 14, the door leaf 6 can slide stably along the inner side of the U-shaped frame 1, thereby realizing the opening or closing of the door leaf 6.

[0027] Furthermore, both sides of the U-shaped frame 1 are provided with sliding grooves 5, which are slidably connected to the side plates 7. The U-shaped frame 1 is slidably connected to the side plates 7 through the sliding grooves 5. The function of the sliding grooves 5 is to enable the two sides of the U-shaped frame 1 to connect with the side plates 7, thereby facilitating the U-shaped frame 1 to connect with the embedded base 9 more quickly.

[0028] Furthermore, insertion holes 18 are provided on both sides of the bottom end of the U-shaped frame 1. The connecting rod 15 is fixedly connected to the embedded base 9. The connecting rod 15 is engaged with the U-shaped frame 1 through the insertion holes 18. The U-shaped frame 1 is engaged with the embedded base 9 through the connecting rod 15 and the side plate 7. The inner diameter of the insertion hole 18 is adapted to the outer diameter of the connecting rod 15, so that the U-shaped frame 1 can stably engage with the connecting rod 15, thereby realizing the rapid positioning and installation of this gate.

[0029] Furthermore, multiple reinforcing bars 8 are fixedly connected to the other side wall of the side plate 7. The function of the reinforcing bars 8 is to strengthen the connection between the side plate 7 and the concrete structure poured in the ditch, thereby improving the stability of the connection between the side plate 7 and the embedded base 9 and the dam.

[0030] The usage method of this embodiment is as follows: When using this quick-installation dam gate, the embedded base 9 needs to be pre-cast and fixed to the concrete structure at the installation point of the gate. At this time, the rebar 8 on the other side wall of the side plate 7 will be connected to the concrete structure, and the side wall of the side plate 7 facing the U-shaped frame 1 will be exposed. At the same time, the connecting rod 15 on the embedded base 9 will also be exposed. Then, the U-shaped frame 1 and the gate leaf 6 can be aligned with the side plate 7 by hoisting. At this time, the two side walls of the U-shaped frame 1 will slide down along the side plate 7 through the sliding groove 5. Then, the bottom end of the U-shaped frame 1 will be connected to the connecting rod 15 on the embedded base 9 through the insertion hole 18. At this time, the U-shaped frame 1 will be connected to the embedded base 9. Then, the gate can be connected to the external connection. When the gate leaf 6 needs to be opened, the forward and reverse motor 4 will rotate forward under the control of the microcontroller, driving the rotating shaft 13 and the spur gear 12 on the rotating shaft 13 to rotate. This causes the spur gear 12 to mesh with the external gear ring 11, causing the external gear ring 11 to drive the internal threaded drum 10 to rotate at the top of the U-shaped frame 1. This causes the internal threaded drum 10 to mesh with the screw 3 and rotate. Under the meshing rotation of the internal threaded drum 10, the screw 3 rises along the U-shaped frame 1, causing the gate leaf 6 to rise along the opening 19 in the middle of the crossbeam 14. At this time, the gate is in the open state. If it is necessary to close the gate, the forward and reverse motor 4 will rotate in the reverse direction, causing the screw 3 to move down and driving the gate leaf 6 to descend until the gate is completely closed.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
