Description

Technical Field

[0001] The present invention relates to the technical field of radial gates, and specifically to a multi-stage mechanical locking device for a radial gate of a hydropower station based on a multi-condition environment. Background Technique

[0002] The radial gate of a hydropower station is a type of gate characterized by an arc-shaped structure and is widely used in scenarios such as water storage and flood discharge in water conservancy and hydropower projects. The working principle of the radial gate of a hydropower station is as follows: The hydraulic hoist drives the piston rod to expand and contract, driving the arc-shaped gate leaf to rotate around the fixed hinge, and adjusting the gate opening to control the water flow. In some designs, a distance measuring device is used to monitor the displacement of the piston rod in real time, and the actual opening is calculated in combination with geometric relationships. In the hydraulic hoist of the radial gate of a hydropower station, multi-stage mechanical locking is used. The principle of mechanical locking is a control function achieved through mechanical equipment to prevent misoperation and ensure the safe operation of the equipment. The structure of the radial gate of a hydropower station consists of components such as a gate leaf, a support arm, a hinge, a water stop device, a guiding device, and a lifting lug. The gate leaf is in a cylindrical arc shape, the support arm is connected to the basic structure through a hinge seat, and the hydraulic hoist drives the gate leaf to rotate around the hinge through the piston rod to achieve opening and closing. Mechanical locking mainly relies on locking cards, connecting rods, or other mechanical structures, which transmit power from one part of the machine to another part to achieve the locking effect. Specifically, mechanical locking restricts each other through the mechanical structures of the operating mechanism of the equipment to achieve an interlocking locking method;

[0003] A prior Chinese patent with the publication number CN204715307U discloses a radial gate for a flood discharge tunnel of a hydropower station dam bank. This prior art includes a civil engineering structure, a radial gate body, a support mechanism, a hydraulic cylinder, and a gate frame. Symmetric slope sealing grooves are provided inside the gate frame, and the radial gate is provided with convex grooves with a shape matching thereto. Sealing strips are provided on the convex grooves, and the radial gate is installed into the sealing grooves of the gate frame to fit together. The civil engineering structure is provided on the left and right sides of the radial gate body, the gate frame is provided below the radial gate body, the support mechanism is fixedly connected to the radial gate body and hinged to the civil engineering structure, the hydraulic cylinder is horizontally fixed on the civil engineering structure, and its piston rod is hinged to the support mechanism. While not affecting flood discharge, the present invention is also convenient for maintenance and repair;

[0004] There is a construction method for river diversion type hydropower station closure, with the Chinese patent publication number CN113981918B. The existing technology includes the following processes. After pouring the concrete of the spillway to the installation height of the hinge seat of the radial gate arm, install a two-hole radial gate on the hinge seat of the radial gate arm. After the installation of the two-hole radial gate is completed, divert the river to flow through the control section of the spillway and start the construction of the asphalt core wall concrete rockfill dam. When the remaining three bottom-hole radial gates are installed after the spillway is poured to the dam crest and during the dry season with small water flow, use the gate leaf of the maintenance gate to block water at the upstream orifice and build surrounding rock to block water at the downstream to install the remaining three bottom-hole radial gates. A construction method that advances the construction of the asphalt core wall concrete rockfill dam. Solve the construction project in the conventional design where the construction period is tight and the early construction period lags behind, resulting in the inability to generate electricity as scheduled for the overall construction;

[0005] However, the above-mentioned device and the existing radial gates of hydropower stations based on multi-condition environments cannot achieve multi-level interlocking during use, and have a poor protection level. When the arc-shaped partition rotating door body is opened at different angles and states, it cannot be stably locked and limited. At the same time, when the door body is opened and closed to different degrees, it cannot accurately detect whether the opening and closing angle is in place, and whether the device for locking the door body is fully operated in place to achieve locking and fixing. Moreover, when used in a complex environment, it cannot conveniently detect the environment and cannot timely repair and maintain the equipment inside the device. Therefore, a device is needed to solve the above problems. Summary of the Invention

The driving adjustment gear is rotatably clamped inside the installation limiting vertical plate. The first motor is fixedly installed on the installation limiting vertical plate, and the installation limiting vertical plate is located between the first sliding adjustment tooth plate and the second sliding adjustment tooth plate.

After the position of the rotating and adjusting frame is adjusted to the specified position, it can be stably maintained. Thus, after the use position of the arc-shaped rotating gate is adjusted to the appropriate position, it can be stably locked and maintained, and the arc-shaped rotating gate can be stably locked for use.

[0017] The present invention has at least the following beneficial effects:

[0018] First, the auxiliary driving and locking main body provided in the present invention can indirectly control the rotation and locking of the arc-shaped rotating gate, so that the position of the arc-shaped rotating gate during use can be accurately and conveniently controlled. And when the auxiliary driving and locking main body is operating, the locking control and adjustment part can simultaneously assist in locking and fixing the arc-shaped rotating gate. When the arc-shaped rotating gate rotates to the specified position, the second motor in the auxiliary driving and locking main body stops operating, and the second arc-shaped tooth plate meshes with the first arc-shaped tooth plate, which can achieve self-locking and fixing of the arc-shaped limiting frame, the rotating and adjusting frame, and the arc-shaped rotating gate, enabling the arc-shaped rotating gate to achieve preliminary locking and fixing. At the same time, start each first motor in the locking control and adjustment part. The first motor can drive each driving and adjusting gear to rotate synchronously. The rotating driving and adjusting gear can make the first sliding and adjusting tooth plate and the second sliding and adjusting tooth plate slide outward along the limiting frame stably synchronously, driving the sliding connection blocks slidably arranged inside both ends of the limiting frame to slide towards both ends of the limiting frame synchronously, so that the locking column penetrates through the limiting disc and inserts into the locking slot at the corresponding position. And the end of the locking column will squeeze the pressure sensor at the corresponding position. When the pressure sensor detects the squeezing force, it will transmit the detected information to the display terminal. By detecting the operation of the pressure sensor at the specified location, it can be judged which locking slot the locking column has inserted into, that is, it can judge whether mechanical locking is achieved, and it can also assist in detecting and judging whether the arc-shaped rotating gate rotates to the specified position for use. And each pressure sensor can be connected to an external display lamp to control the external display lamp. The lamp being on indicates that the insertion and locking are achieved.

[0019] Second, the present invention symmetrically and fixedly arranges auxiliary locking hydraulic cylinders inside the limiting installation dam. Starting the auxiliary locking hydraulic cylinders drives the friction discs at the front end to fully squeeze and fix the side ends of the swing limiting frame, which can assist in locking and limiting the swing limiting frame, so that the arc driving locking frame and the second arc-shaped tooth plate are stable. The second arc-shaped tooth plate plays a role in stably assisting in locking the first arc-shaped tooth plate, so that after the position of the rotation adjustment frame is adjusted to the specified position, it can be stably maintained. Therefore, after the use position of the arc-shaped rotating gate is adjusted to the appropriate position, it can be stably locked and maintained, and the arc-shaped rotating gate can be stably locked for use.

The limit disc 13 is fixedly installed in the middle of the rotating adjustment frame 12. The arc limit frame 17 is fixedly connected to the side end of the rotating adjustment frame 12 away from the fixed connection plate 11. The rotating limit card shafts 14 are fixedly connected to the middle of both ends of the arc limit frame 17. The first fixed limit discs 15 are distributed on the outer sides of both ends of the arc limit frame 17, and the rotating limit card shafts 14 are rotatably clamped in the middle of the first fixed limit discs 15. The locking control adjustment part 19 is arranged between the limit discs 13. By connecting with an external lifting device through an auxiliary lifting hook 20, the rotating adjustment frame 12 can be controlled to rotate around the rotating limit card shaft 14. At this time, the arc rotating gate 8 can stably slide and adjust the position used inside the arc limit card slot 5, so that the opening and closing of the arc rotating gate 8 can be conveniently controlled. First arc tooth plates 16 are fixedly installed on the outer sides of both ends of the arc limit frame 17.

The locking card slots 6 and the pressure sensors 7 can be numbered for convenient detection and judgment.

[0031] As Figure 5As shown, the locking control adjustment part 19 includes a locking clamping post 21, a sliding connection clamping block 22, a limiting frame 23, a first sliding adjustment tooth plate 24, a mounting limiting vertical plate 25, a first motor 26, a driving adjustment gear 27, and a second sliding adjustment tooth plate 28. The sliding connection clamping blocks 22 are symmetrically distributed, and the two sliding connection clamping blocks 22 are slidably clamped inside the limiting frame 23. The first sliding adjustment tooth plate 24 and the second sliding adjustment tooth plate 28 are evenly distributed, and the ends of the first sliding adjustment tooth plate 24 and the second sliding adjustment tooth plate 28 are respectively fixedly connected to the side ends of the sliding connection clamping block 22.

The driving adjustment gear 27 is respectively meshed with the first sliding adjustment tooth plate 24 and the second sliding adjustment tooth plate 28. By the first motor 26, each driving adjustment gear 27 can be driven to rotate synchronously. The rotating driving adjustment gear 27 can make the first sliding adjustment tooth plate 24 and the second sliding adjustment tooth plate 28 slide outwards along the limiting frame 23 stably synchronously. At this time, the sliding connection clamping blocks 22 slidably arranged inside both ends of the limiting frame 23 are driven to slide towards both ends of the limiting frame 23 synchronously, so that the locking clamping post 21 penetrates through the limiting disc 13 and inserts into the corresponding locking slot 6 inside, and the end of the locking clamping post 21 presses the pressure sensor 7 at the corresponding position. When the pressure sensor 7 detects the extrusion force, the detected information is transmitted to the display terminal. By detecting the operation of the pressure sensor 7 at the specified position, it can be judged which locking slot 6 the locking clamping post 21 inserts into, that is, it can judge whether mechanical locking is achieved, and it can also assist in detecting and judging whether the arc rotating gate 8 rotates to the specified position for use.

[0032] As Figure 6As shown in the figure, the auxiliary drive locking body 3 includes a second arc-shaped tooth plate 30, an arc-shaped drive locking frame 31, a second motor 32, a swing limit frame 33, an angle sensor 34, and a second fixed limit disk 35. The second fixed limit disks 35 are distributed on the outer sides of both ends of the swing limit frame 33. The second motor 32 is fixedly installed on the second fixed limit disk 35 distributed on one side. The swing limit frame 33 is fixedly connected to the outer end of the arc-shaped drive locking frame 31. The angle sensor 34 is fixedly installed on the second fixed limit disk 35 distributed on the other side. One end of the swing limit frame 33 is connected to the angle sensor 34. The drive end of the second motor 32 is fixedly connected to the end of the swing limit frame 33 facing away from the angle sensor 34. Second arc-shaped tooth plates 30 are symmetrically and fixedly installed on the inner side of the arc-shaped drive locking frame 31. Starting the second motor 32 can drive the swing limit frame 33 and the arc-shaped drive locking frame 31 to rotate forward and backward, thereby driving the second arc-shaped tooth plate 30 to rotate. The rotating second arc-shaped tooth plate 30 can control the arc-shaped limit frame 17 to rotate around the rotating limit card shaft 14 through the first arc-shaped tooth plate 16.

[0033] The second arc-shaped tooth plate 30 is meshed and connected with the first arc-shaped tooth plate 16. Both the second fixed limit disk 35 and the first fixed limit disk 15 are fixedly installed on the limit installation dam 1 through pins and screws. The arc-shaped rotating gate 8 is adapted to the arc-shaped limit card slot 5. The limit frame 23 is fixedly installed between the limit disks 13. The locking column 21 is inserted through the middle of the limit disks 13. The locking column 21 is adapted to the locking card slot 6, so that the locking column 21 can be inserted into the inside of the locking card slot 6 to achieve locking and fixing.

[0034] The working principle of Embodiment 1 is as follows: During use, the auxiliary lifting hook 20 is connected to an external lifting device, which can control the rotation of the rotation adjustment frame 12 around the rotation limit card shaft 14. At this time, the arc-shaped rotating gate 8 can stably slide and adjust its position inside the arc-shaped limit card slot 5, so as to conveniently control the opening and closing of the arc-shaped rotating gate 8. Starting the second motor 32 can drive the swing limit frame 33 and the arc-shaped drive locking frame 31 to rotate forward and backward, thereby driving the second arc-shaped tooth plate 30 to rotate. The rotating second arc-shaped tooth plate 30 can control the rotation of the arc-shaped limit frame 17 around the rotation limit card shaft 14 through the first arc-shaped tooth plate 16. Thus, the rotating arc-shaped limit frame 17 can drive the rotation adjustment frame 12 to rotate, and the rotating rotation adjustment frame 12 can control the rotation of the arc-shaped rotating gate 8, making it convenient to control the position and angle of the arc-shaped rotating gate 8 during rotation. And through the angle sensor 34, the rotation angles of the arc-shaped drive locking frame 31 and the second arc-shaped tooth plate 30 can be detected and controlled, indirectly detecting and monitoring the position of the arc-shaped rotating gate 8 during rotation. When the arc-shaped rotating gate 8 rotates to the specified position, stop the operation of the second motor 32 at this time. At this time, the second arc-shaped tooth plate 30 meshes with the first arc-shaped tooth plate 16, which can realize self-locking fixation of the arc-shaped limit frame 17, the rotation adjustment frame 12, and the arc-shaped rotating gate 8, making the arc-shaped rotating gate 8 achieve preliminary locking and fixation. Then start each first motor 26 simultaneously. Through the first motor 26, each drive adjustment gear 27 can be driven to rotate synchronously. The rotating drive adjustment gear 27 can make the first sliding adjustment tooth plate 24 and the second sliding adjustment tooth plate 28 slide outward along the limit frame 23 stably at the same time. At this time, the sliding connection blocks 22 slidably arranged inside both ends of the limit frame 23 are driven to slide towards both ends of the limit frame 23 synchronously, so that the locking column 21 penetrates the limit disk 13 and inserts into the corresponding locking card slot 6 inside, and the end of the locking column 21 will squeeze the pressure sensor 7 at the corresponding position. When the pressure sensor 7 detects the extrusion force, the detected information is transmitted to the display terminal. By detecting the operation of the pressure sensor 7 at the specified location, it can be judged which locking card slot 6 the locking column 21 is inserted into, that is, it can be judged whether mechanical locking is achieved, and it can also assist in detecting and judging whether the arc-shaped rotating gate 8 rotates to the specified position for use. And each pressure sensor 7 can control an external display lamp. When the lamp is on, it means that the insertion and locking are achieved. The evenly distributed sensors 18 are respectively a temperature sensor, a humidity sensor, and an MT30 illuminance transmitter, which can detect the humidity, temperature, and illuminance of the use environment in real time, so as to facilitate the timely protection, maintenance, and detection of the electrical equipment inside this device.

The auxiliary locking hydraulic cylinders 4 are located outside the swing limiting frame 33.

[0037] When implementing this embodiment, by symmetrically and fixedly arranging the auxiliary locking hydraulic cylinders 4 on the inner side of the limiting installation dam 1, starting the auxiliary locking hydraulic cylinders 4 to drive the friction discs at the front ends to fully squeeze and fix the side ends of the swing limiting frame 33 can assist in locking and limiting the swing limiting frame 33, so that the arc driving and locking frame 31 and the second arc-shaped tooth plate 30 are stabilized, enabling the second arc-shaped tooth plate 30 to play a role in stabilizing and assisting in locking the first arc-shaped tooth plate 16, so that the position of the rotation adjustment frame 12 can be stably maintained after being adjusted to the specified position, and thus the use position of the arc-shaped rotating gate 8 can be stably locked and maintained after being adjusted to a suitable position, and the arc-shaped rotating gate 8 can be stably locked for use.
