[0001] The utility model relates to the technical field of gates, in particular to a water conservancy and hydropower gate device. Background Art

[0002] Gates are currently commonly used in the field of water conservancy projects, mainly to cut off the water flow. They can effectively control the flow of water in hydropower generation. Gates are usually raised and lowered by a special lifting mechanism to control the amount of water in each waterway.

[0003] The existing gates are easily corroded by water vapor due to long-term contact with water. When the gates are seriously corroded, the entire gate needs to be replaced, which is extremely wasteful. Moreover, when the gates are replaced, the effect of cutting off the water flow and controlling the flow rate will disappear. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the existing gates are easily corroded by water vapor due to long-term contact with water. When the gates are seriously corroded, the entire gates need to be replaced, which is extremely wasteful. When the gates are replaced, the effects of water flow cutoff and water flow control will disappear. A water conservancy and hydropower gate device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, the elastic component comprises a torsion spring sleeved on the rotating rod, a fixing block is fixedly mounted on one end of the rotating rod, and two ends of the torsion spring are fixedly connected to the fixing block and the protective plate respectively.

[0009] Preferably, the lifting mechanism comprises a lifting cylinder fixedly mounted on the upper surface of the frame, and a driving shaft of the lifting cylinder is fixedly connected to the gate.

[0010] Preferably, a limiting component is provided on the surface of the protective plate, and the limiting component is used to limit the rotation of the rotating rod.

[0012] Preferably, the side walls around the protective plate are bonded with sealing layers, and the sealing layers are made of rubber.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The protective plate design can replace the gate contact with water, avoiding direct contact between the gate and water, which would cause the gate to be corroded by water vapor.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0024] Reference Figure 1-Figure 5 A water conservancy and hydropower gate device comprises a frame 1 and two L-shaped protective plates 2. The left and right side walls of the frame 1 are vertically provided with slide grooves. The two slide grooves are vertically sealed and slidably inserted with gates 3. The gates 3 are controlled to move vertically by a lifting mechanism. The lifting mechanism comprises a lifting cylinder 9 fixedly mounted on the upper surface of the frame 1. The driving shaft of the lifting cylinder 9 is fixedly connected to the gate 3. The two protective plates 2 are engaged with the surface of the gate 3.

[0025] A rotating opening is horizontally opened on the surface of the protective plate 2, and a rotating rod 4 is sealed and rotatably installed in the rotating opening. The rotating rod 4 is connected to the protective plate 2 through an elastic component. The elastic component includes a torsion spring 8 sleeved on the rotating rod 4. A fixing block is fixedly installed on one end of the rotating rod 4. The two ends of the torsion spring 8 are respectively fixedly connected to the fixing block and the protective plate 2. A mounting block 5 is symmetrically fixedly installed on the surface of one end of the rotating rod 4. A socket 6 is horizontally opened on the surface of the protective plate 2. A through hole 7 is symmetrically opened horizontally on the wall of the socket 6. The socket 6 and the through hole 7 are used for the rotating rod 4 and the mounting block 5 to pass through;

[0026] Two protective plates 2 that are engaged with the surface of the gate 3 and locked with each other can replace the gate 3 in contact with water, thereby preventing the gate 3 from directly contacting water and causing the gate 3 to be corroded by water vapor;

[0027] When it is necessary to install the two protective plates 2, firstly, the two protective plates 2 are engaged with the gate 3. When the two protective plates 2 are approaching each other, the two rotating rods 4 are controlled to rotate so that the multiple installation blocks 5 correspond to the positions of the multiple through openings 7 respectively. Then, the two rotating rods 4 are controlled to be inserted into the two sockets 6 respectively until the two protective plates 2 are butted against each other and can be completely engaged with the surface of the gate 3. At this time, the multiple installation blocks 5 will be moved out of the multiple through openings 7. At this time, the rotating rod 4 is released, and the rotating rod 4 will quickly rotate and reset under the elastic potential energy of the torsion spring 8. At this time, the multiple installation blocks 5 will quickly rotate until they no longer correspond to the positions of the multiple through openings 7, and the two rotating rods 4 will no longer move in the horizontal direction, thereby completing the locking of the two protective plates 2.

[0028] When it is necessary to disassemble the two protective plates 2, it is only necessary to rotate the two rotating rods 4 again, control the two rotating rods 4 to rotate until the multiple mounting blocks 5 at the ends are respectively rotated to correspond to the positions of the multiple through openings 7, and then control the two protective plates 2 to move away from each other, so that the rotating rods 4 can be removed from the sockets 6, which is convenient for replacing the corroded protective plates 2, without replacing the entire gate 3, avoiding waste;

[0029] When the protective plate 2 is replaced, the position of the gate 3 will not change, so the gate 3 can still achieve the effect of cutting off the water flow and controlling the water flow, and the effect of cutting off the water flow and controlling the water flow will not disappear due to the replacement of the corroded protective plate 2.

[0030] A limiting assembly is provided on the surface of the protective plate 2, and the limiting assembly is used to limit the rotation of the rotating rod 4. The limiting assembly includes a mounting plate fixedly mounted on the surface of the protective plate 2, a spring rod 10, and a U-shaped limiting block 11 fixedly mounted on one end of the spring rod 10. The spring rod 10 is horizontally fixedly mounted on the surface of the mounting plate, and the limiting block 11 is used to clamp the mounting block 5;

[0031] Before installing the two protective plates 2, control the spring rod 10 to retract. When the two protective plates 2 are locked, one of the mounting blocks 5 at the end of the rotating rod 4 will correspond to the position of the limiting block 11. Then release the spring rod 10, and the limiting block 11 will quickly move and reset under the elastic potential energy of the spring rod 10. The mounting block 5 corresponding to its position will be snapped into the limiting block 11, thereby limiting the rotation of the rotating rod 4 and improving the installation stability of the two protective plates 2. When it is necessary to control the rotation of the rotating rod 4, just control the spring rod 10 to retract and separate the mounting block 5 from the limiting block 11 to release the restriction on the rotating rod 4.

[0032] The side walls around the protective plate 2 are all bonded with sealing layers, and the material of the sealing layers is rubber. The sealing layers made of rubber can increase the sealing between the contact surface of the protective plate 2 and the frame 1.

[0033] In the present invention, when it is necessary to install the two protective plates 2, the two protective plates 2 are first engaged on the gate 3. When the two protective plates 2 are approaching each other, the two rotating rods 4 are controlled to rotate so that the multiple installation blocks 5 correspond to the positions of the multiple through openings 7 respectively. Then, the two rotating rods 4 are controlled to be inserted into the two sockets 6 respectively until the two protective plates 2 are abutted against each other and can be completely engaged on the surface of the gate 3. At this time, the multiple installation blocks 5 will all be moved out of the multiple through openings 7. At this time, the rotating rod 4 is released, and the rotating rod 4 will quickly rotate and reset under the elastic potential energy of the elastic component. At this time, the multiple installation blocks 5 will quickly rotate until they no longer correspond to the positions of the multiple through openings 7, and the two rotating rods 4 will no longer move in the horizontal direction, thereby completing the locking of the two protective plates 2. When it is necessary to disassemble the two protective plates 2, It is only necessary to rotate the two rotating rods 4 again, control the two rotating rods 4 to rotate until the multiple mounting blocks 5 at the ends rotate to the positions corresponding to the multiple openings 7, and then control the two protective plates 2 to move away from each other, so that the rotating rod 4 is moved out of the socket 6. The two protective plates 2 that are engaged with the surface of the gate 3 and locked with each other can replace the gate 3 to contact with water, avoiding direct contact between the gate 3 and water, thereby causing the gate 3 to be corroded by water vapor, and facilitating the replacement of the corroded protective plates 2 without replacing the entire gate 3 to avoid waste. In addition, in the process of replacing the protective plates 2, since the position of the gate 3 will not change, the gate 3 can still achieve the effect of cutting off the water flow and controlling the water flow, and the effect of cutting off the water flow and controlling the water flow will not disappear due to the replacement of the corroded protective plates 2.

[0034] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
