Description

Technical Field

[0001] The utility model belongs to the technical field of storage door trough cover plates, and in particular relates to an automatic flip opening and closing device for a storage door trough steel grille cover plate of a hydropower station. Background Art

[0002] Existing hydropower station storage gate trough covers are mostly made of reinforced concrete covers, which are manually opened and closed by equipment such as gantry cranes on the dam surface.

[0003] However, due to factors such as large dimensional variations in the cover panels themselves, the low hoisting accuracy of traditional lifting equipment, and the low flatness of the hoisting position, in a gate hangar with multiple cover panels in parallel, after the previous panels have been hoisted, there is little space left for the last cover panel, making it impossible to install the last cover panel. Furthermore, the heavy weight of the cover panels makes hoisting inefficiency, which in turn reduces the efficiency of opening and closing the hydropower station's storage gate slots. Utility Model Content

[0004] The utility model provides an automatic flip opening and closing device for a steel grille cover plate of a storage gate trough of a hydropower station, so as to solve the problem of low opening and closing efficiency of the storage gate trough of the hydropower station.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An automatic flip opening and closing device for a steel grille cover of a storage gate trough of a hydropower station, comprising a first grille cover and a second grille cover rotatably mounted on the storage gate trough, wherein the first grille cover and the second grille cover are arranged side by side and can rotate relative to each other in a direction away from the bottom wall of the storage gate trough;

[0007] The side wall of the first grid cover plate adjacent to the rotating end and the side wall of the second grid cover plate adjacent to the rotating end are both installed with a flip driving device, and the flip driving device is also fixed to the bottom wall of the storage door slot.

[0008] Furthermore, the flipping drive device includes a base, on which a lifting shaft is fixed. The lifting shaft is arranged at an angle, and one end of the lifting shaft is fixed to the bottom wall of the storage door slot, and the other end is hinged to the first grid cover plate and the second grid cover plate. The middle part of the lifting shaft is fixed to the top of the base.

[0009] Furthermore, the lifting shaft includes a mounting tube, one end of which is fixed to the bottom wall of the storage door slot and the other end is fixed to the top of the base;

[0010] A support rod is slidably inserted in the installation cylinder, and one end of the support rod away from the installation cylinder is hinged to the first grid cover plate and the second grid cover plate. A driving source is provided in the installation cylinder to drive the support rod to move away from the installation cylinder.

[0011] Furthermore, sealing covers are fixed at the hinge points of the first grid cover plate, the second grid cover plate and the lifting shaft rod. When the first grid cover plate and the second grid cover plate are covered on the storage door slot, the sealing covers cover the top of the installation tube.

[0012] Furthermore, the inner diameter of the sealing cover is larger than the outer diameter of the mounting cylinder.

[0013] Furthermore, when the first grid cover plate and the second grid cover plate are both covered on the storage door slot, the free ends of the first grid cover plate and the second grid cover plate are connected, and a main support seat is fixed to the bottom wall of the storage door slot, and the free ends of the first grid cover plate and the second grid cover plate are both overlapped on the main support seat.

[0014] Furthermore, auxiliary support seats are provided between the base and the rotating side of the first grid cover plate, and between the base and the rotating side of the second grid cover plate. When the first grid cover plate and the second grid cover plate are covered, the auxiliary support seats support the first grid cover plate and the second grid cover plate.

[0015] Furthermore, a limit hinge is provided between the first grid cover plate, the second grid cover plate and the bottom wall of the storage door slot. When the first grid cover plate and the second grid cover plate are rotated to the maximum position, the limit hinge is straightened.

[0016] The utility model can achieve the following beneficial effects:

[0017] 1. The automatic flipping device of the present application can realize the automatic opening of the storage gate trough cover plate under the premise of meeting the bearing capacity of the dam surface, improve the opening and closing efficiency of the storage gate trough cover plate, and reduce the risk of the cover plate opening and closing process; through the separate control of the flipping drive device, it can realize the three states of separate opening of the first grid cover plate or the second grid cover plate, double opening of the first grid cover plate and the second grid cover plate, and complete closure of the first grid cover plate and the second grid cover plate, so as to flexibly switch according to the needs of the gate opening and closing operation.

[0018] 2. The present application fixes a sealing cover on the first grid cover plate and the second grid cover plate. When the first grid cover plate and the second grid cover plate are closed, the sealing cover covers the top of the mounting tube, thereby limiting the entry of pollutants into the gap between the mounting tube and the support rod, thereby increasing the service life of the lifting shaft rod.

[0019] 3. The main support seat and the auxiliary support seat can achieve stable support for the first grid cover plate and the second grid cover plate. The setting of the limit hinge can limit the rotation degree of the first grid cover plate and the second grid cover plate, reducing the possibility of excessive rotation of the first grid cover plate and the second grid cover plate.

[0026] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0027] like Figures 1 to 3 As shown, the storage gate trough is a storage space excavated underground by a hydropower station for storing equipment. The flip-up opening and closing device of the present application is arranged above the storage gate trough to cover the storage gate trough. An automatic flip-up opening and closing device for a steel grating cover of a storage gate trough of a hydropower station comprises a first grating cover plate 1 and a second grating cover plate 2 arranged side by side, wherein one side edge of the first grating cover plate 1 is rotatably connected to a side wall of the storage gate trough, and one side edge of the second grating cover plate 2 is rotatably connected to the other side wall opposite the storage gate trough, and the free ends of the first grating cover plate 1 and the second grating cover plate 2 are in contact when the first grating cover plate 1 and the second grating cover plate 2 cover the storage gate trough.

[0028] A flip drive device 3 is disposed between each of the first and second grille covers 1 and 2 and the bottom wall of the storage door slot. The flip drive device 3 is configured to drive the first and second grille covers 1 and 2 to rotate away from the bottom wall of the storage door slot. The flip drive device 3 includes a base 31 and a lifting shaft 32 fixed to the base 31. The lifting shaft 32 is tilted and includes a mounting tube 321 and a support rod 322 that slides into the mounting tube 321. The mounting tube 321 has one end fixed to the base 31 and the other end fixed to the bottom wall of the storage door slot. The support rod 322 has one end that slides into the mounting tube 321 and the other end that is hinged to the surface of the first or second grille cover 1 or 2.

[0029] The lifting shaft 32 also includes a driving source for driving the supporting rod 322 to slide along the mounting tube 321. The supporting rod 322 can be moved by pneumatic propulsion. It should be noted that the straight-line distance between the hinge point of the supporting rod 322 and the rotating edge of the first grid cover 1 is consistent with the depth of the bottom wall of the storage door slot at the corresponding position of the base 31. Therefore, the setting length of the supporting rod 322 and the mounting tube 321 is consistent. When the supporting rod 322 is fully stored in the mounting tube 321, the supporting rod 322 can also push the first grid cover 1 to rotate to a vertical state. The second grid cover 2 is set in the same manner.

[0030] Two sets of flip drive devices 3 are respectively disposed below the first and second grid cover plates 1, 2. Taking the first grid cover plate 1 as an example, the two sets of flip drive devices 3 are respectively disposed on the two sides of the first grid cover plate 1 adjacent to the rotating side. The first grid cover plate 1 can be rotated by synchronously driving the two sets of flip drive devices 3.

[0031] Furthermore, a sealing cover 4 is fixed at the hinge point between the first and second grille covers 1 and 2 and the support rod 322. The hinge point is set inside the sealing cover 4, and the inner diameter of the sealing cover 4 is larger than the outer diameter of the mounting tube 321. Therefore, when the first and second grille covers 1 and 2 are covered above the storage door slot, the sealing cover 4 can surround and cover the side of the mounting tube 321. The provision of the sealing cover 4 can reduce the entry of dust or dirt into the gap between the support rod 322 and the mounting tube 321. At the same time, it can guide water leaking from the first and second grille covers 1 and 2, reducing water leakage between the support rod 322 and the mounting tube 321. This reduces the possibility of the support rod 322 getting stuck or rusted, reduces the maintenance cost of the lifting shaft 32, and increases the service life of the lifting shaft 32.

[0032] The bottom wall of the storage door slot is also provided with a main support seat 5 and a secondary support seat 6. The main support seat 5 is provided in the middle of the storage door slot; the secondary support seat 6 is provided between the flip drive device 3 and the rotating side of the first grid cover plate 1, or between the flip drive device 3 and the rotating side of the second grid cover plate 2. When the first grid cover plate 1 and the second grid cover plate 2 cover the storage door slot, the free ends of the first grid cover plate 1 and the second grid cover plate 2 overlap the main support seat 5, and the areas of the first grid cover plate 1 and the second grid cover plate 2 near the rotating side overlap the secondary support seat 6. The provision of the main support seat 5 and the secondary support seat 6 can achieve stable support for the first grid cover plate 1 and the second grid cover plate 2.

[0033] Limit hinges 7 are provided between the first grid cover 1 and the bottom wall of the storage door slot, and between the second grid cover 2 and the bottom wall of the storage door slot. When the first and second grid covers 1 and 2 are rotated to their maximum positions, the limit hinges 7 straighten. The provision of the limit hinges 7 limits the rotation angles of the first and second grid covers 1 and 2, thereby limiting the driving effect of the tilting drive device 3 on the first and second grid covers 1 and 2.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
