Description

Technical Field

[0001] This utility model relates to the field of hydropower station equipment technology, and in particular to a protective gate for hydropower station construction. Background Technology

[0002] A hydropower station is a comprehensive engineering facility that converts water energy into electrical energy. It typically consists of a hydraulic system, a mechanical system, and an electrical energy generation device. Depending on the water source, hydropower stations can be classified into conventional hydropower stations, pumped storage power stations, and tidal power stations. Among them, the protective gate is an important facility in a hydropower station used to ensure safe operation and is mainly used for maintenance work during normal operation.

[0003] A search revealed that the announcement number is CN212506146U, and the name is a protective gate for the construction of a hydropower station, including a bottom dam, a gate mechanism and a winch. Through research and analysis, it was found that although it greatly reduces the weight of the gate lifting and reduces the overall workload, it still has the following disadvantages to a certain extent.

[0004] For example, if the device only uses a through hole for drainage, it cannot quickly discharge the intercepted water flow in scenarios that require rapid water discharge and flood control. It also lacks the function of diversion and buffering, and the water flow directly impacts the gate, affecting the service life of the gate.

[0005] Therefore, it is necessary to develop a protective gate for hydropower station construction to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to design a protective gate for the construction of hydropower stations in order to solve the above problems.

[0007] This utility model achieves the above objectives through the following technical solutions:

[0008] A protective gate for the construction of a hydropower station, comprising:

[0009] Gate frame;

[0010] Stabilizer; Both the stabilizer and the gate frame are U-shaped structures. The stabilizer is installed above the gate frame, and the stabilizer and the gate frame are combined to form a rectangular frame structure.

[0011] Displacement gate; the inner walls on both sides of the gate frame are provided with sliding grooves, and the two sides of the displacement gate are slidably placed in the sliding grooves. The sliding direction of the displacement gate is vertical. The displacement gate is provided with multiple first drainage holes and multiple first drainage channels. The first drainage channel is placed above the first drainage hole.

[0012] Fixed gate plate; the two ends of the fixed gate plate are fixedly installed on the inner walls of both sides of the gate frame, and the displacement gate plate is parallel to the fixed gate plate; corresponding to the setting positions of the first drainage hole and the first water discharge groove on the displacement gate plate, multiple second drainage holes and multiple second water discharge grooves are set on the fixed gate plate; the second water discharge grooves are placed above the second drainage holes;

[0013] At least one electric hoist; the electric hoist is mounted on a stabilizer, and the suspended end of the electric hoist is connected to a displacement gate.

[0014] Specifically, hanging rings are fixedly connected to both the left and right sides of the top of the displacement gate, and the suspension end of the electric hoist is connected to the hanging rings via steel cables.

[0015] Furthermore, the displacement gate is provided with multiple protruding ridges on the surface away from the fixed gate, and the protruding ridges are arranged vertically.

[0016] Specifically, the protective gate for hydropower station construction also includes a movable barrier component, which includes a geared motor, a screw, multiple toothed plates, multiple water-blocking blades, multiple positioning shafts, a displacement plate, and multiple teeth. The geared motor is installed upside down on the top of the stabilizer. The upper end of the screw is connected to the shaft of the geared motor. The displacement plate has a screw hole along its length. The screw and the displacement plate are threaded together. Multiple toothed plates are vertically fixed on both sides of the displacement plate. The first end of the positioning shaft is fixedly installed on the fixed gate plate, near the second spillway. The first end of the water-blocking blade is rotatably mounted on the second end of the positioning shaft through a bearing. The teeth are installed on the outside of the first end of the water-blocking blade and mesh with the toothed plate.

[0017] Preferably, there are six toothed plates, six water-blocking blades, six positioning shafts, and six toothed teeth, with the six toothed plates symmetrically distributed along the vertical axis of the displacement plate.

[0018] Furthermore, the dimensions of the first drainage channel, the second drainage channel, and the water-blocking blade increase sequentially.

[0019] The beneficial effects of this utility model are as follows:

[0020] By incorporating a displacement gate, convex ribs, a fixed gate, and movable blocking components, this system offers advantages in both rapid drainage and buffering. When rapid drainage is required, the geared motor is controlled to operate, and with the cooperation of the screw and the displacement plate, the toothed plate gradually moves downward. Under the engagement of the teeth, the water-blocking blade rotates around the positioning shaft and is misaligned with the second drainage channel, allowing high-level water to be discharged through the first and second drainage channels. During water accumulation, the convex ribs can divert the water flow to the side, reducing the impact force on the displacement gate and ensuring the service life of the equipment.

[0032] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1-4 As shown, a protective gate for the construction of a hydropower station includes:

[0034] Gate frame 1;

[0035] Stabilizer 5; Stabilizer 5 and gate frame 1 are both formed into U-shaped structures. Stabilizer 5 is installed above gate frame 1. Stabilizer 5 and gate frame 1 are combined to form a rectangular frame structure.

[0036] Displacement gate 3; Slide grooves are provided on the inner walls of both sides of the gate frame 1, and the two sides of the displacement gate 3 are slidably placed in the slide grooves. The sliding direction of the displacement gate 3 is vertical. Multiple first drainage holes 7 and multiple first drainage channels 2 are provided on the displacement gate 3. The first drainage channels 2 are placed above the first drainage holes 7.

[0037] Fixed gate plate 8; both ends of fixed gate plate 8 are fixedly installed on the inner walls of both sides of gate frame 1, displacement gate plate 3 is parallel to fixed gate plate 8; corresponding to the setting positions of the first drainage hole 7 and the first drainage groove 2 on displacement gate plate 3, a plurality of second drainage holes 9 and a plurality of second drainage grooves 11 are provided on fixed gate plate 8; the second drainage grooves 11 are placed above the second drainage holes 9.

[0038] Two electric hoists 4; the two electric hoists 4 are installed on the stabilizer 5, and hanging rings are fixedly connected to the left and right sides of the top of the displacement gate 3. The suspension ends of the two electric hoists 4 are respectively connected to the two hanging rings through steel cables.

[0039] The movable barrier assembly 10 includes a geared motor 1001, a screw 1002, six toothed plates 1003, six water-blocking blades 1004, six positioning shafts 1005, a displacement plate 1006, and six teeth 1007. The geared motor 1001 is inverted and mounted on the top of the stabilizer 5. The upper end of the screw 1002 is connected to the shaft of the geared motor 1001. The displacement plate 1006 has a screw hole along its length. The screw 1002 and the displacement plate 1006 are connected. The six toothed plates 1003 are vertically fixed on both sides of the displacement plate 1006 with a threaded fit. The first end of the positioning shaft 1005 is fixedly mounted on the fixed gate plate 8, near the second drain groove 11. The first end of the water-blocking blade 1004 is rotatably mounted on the second end of the positioning shaft 1005 via a bearing (optionally a cylindrical roller bearing). The teeth 1007 are installed on the outer side of the first end of the water-blocking blade 1004 and mesh with the toothed plates 1003. The six toothed plates 1003 are symmetrically distributed along the vertical axis of the displacement plate 1006, and correspondingly, the water-blocking blade 1004, the positioning shaft 1005, and the teeth 1007 are also symmetrically distributed along the vertical axis of the displacement plate 1006. The dimensions of the first drain groove 2, the second drain groove 11, and the water-blocking blade 1004 increase sequentially. The displacement plate 1006 cannot rotate under the cooperation of the toothed teeth 1007 and the toothed plate 1003, so the displacement plate 1006 can only move up and down stably under the drive of the geared motor 1001.

[0040] In some embodiments, the displacement gate 3 is provided with a plurality of protruding ribs 6 on the surface away from the fixed gate 8, and the protruding ribs 6 are arranged vertically.

[0041] By setting the water-blocking blade 1004, the second drainage trough 11 can be blocked and covered in the initial state to prevent the accumulated water from being discharged randomly. By setting the displacement gate 3 and the fixed gate 8, a double interception structure can be formed to reduce the working load of the electric hoist 4. By setting the convex ribs 6, the water can be divided to both sides when it is impacted by the water flow in a straight direction. Since there are multiple convex ribs 6, when the water flow is divided between two adjacent convex ribs 6, the two divided water flows will impact each other to further reduce the impact force. When the toothed plate 1003 moves up and down, the water-blocking blade 1004 will rotate around the positioning shaft 1005. The surface of the displacement gate 3 slides and makes contact with the connection between it and the gate frame 1 and performs a sealing treatment.

[0042] In practical applications, in order to improve the rotational stability of the screw 1002, the bottom surface of the screw 1002 is designed to be smooth, and it is movably connected to the gate frame 1 through a bearing, which can effectively improve the operational stability of the screw 1002.

[0043] In use, all components are in their initial state. The first drainage trough 2 and the second drainage trough 11, the first drainage hole 7 and the second drainage hole 9 are all misaligned. At this time, the displacement gate 3 will intercept the water flow. When the water flows straight and impacts the displacement gate 3, the water flow is dispersed to the side due to the design of the convex rib 6 and the displacement gate 3, effectively reducing the impact force on the displacement gate 3, ensuring the service life of the displacement gate 3, and facilitating the lifting or lowering of the displacement gate 3. When slow drainage is required, the electric hoist 4 is controlled to work, pulling the displacement gate 3 upward, so that the first drainage hole 7 and the second drainage hole 9 coincide and align, and the first drainage trough 2 and the second drainage trough 9 are aligned. When the water-blocking blade 1004 covers and blocks the second drain trough 11, the water can only be discharged through the first drain hole 7 and the second drain hole 9. When rapid drainage is required, the reduction motor 1001 is controlled to work, driving the screw 1002 to rotate forward. Under the screw transmission, the displacement plate 1006 drives the toothed plate 1003 to move down stably. Under the meshing transmission of the teeth 1007, the water-blocking blade 1004 will rotate around the positioning shaft 1005 and no longer overlap with the second drain trough 11. At this time, the high-level water will be discharged through the first drain trough 2 and the second drain trough 11. In conjunction with the first drain hole 7 and the second drain hole 9, a dual rapid drainage operation can be achieved.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
