Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, and particularly relates to a flood discharge gate for water conservancy and hydropower. Background Technique

[0002] Flood discharge gates for water conservancy and hydropower are provided in many reservoirs. They are important facilities in water conservancy projects. They are mainly used to control water flow and have functions such as flood prevention, water diversion, and water discharge, which are crucial for water resource management and flood prevention projects. Some existing flood discharge gates for water conservancy and hydropower drive the gate to move upward through a screw rod. The screw rod is exposed to the outside for a long time. When it rains outdoors, the screw rod will be washed by rainwater and is exposed to long-term sunlight. Even if there is a protective coating on the outside of the screw rod, rust will occur relatively quickly, and the overall service life is short. It requires manual regular maintenance and replacement. After a large amount of lubricating oil volatilizes on the outside of the screw rod, it is more laborious to drive the screw rod to rotate, making it difficult to open the gate and inconvenient to use.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figure 1-5, in the embodiment of the utility model, a flood discharge gate for water conservancy and hydropower projects includes a limit frame 10. A water isolation plate 11 is slidably connected inside the limit frame 10. A rectangular seat 13 is fixedly connected to the top of the limit frame 10. A top plate 131 is fixedly connected to the top of the rectangular seat 13. A shaft seat 15 is rotatably connected to the top of the top plate 131. A screw rod 151 is screwed inside the shaft seat 15. The bottom end of the screw rod 151 is fixedly connected to the water isolation plate 11. A U-shaped frame 16 is slidably connected to the front side of the limit frame 10. An oil storage box 17 and a permeable block 171 are fixedly embedded inside the rectangular seat 13. A control module 18 is arranged inside the rectangular seat 13. The control module 18 is used to control the oil storage box 17. A driving module 19 is arranged on the top of the top plate 131. The driving module 19 is used to drive the screw rod 151.

[0036] Specifically, an oil storage box 17 is fixedly embedded inside the rectangular seat​​​​​​​​​​In this embodiment, the heat insulation sleeve 132 is made of ceramic fiber material, which has excellent heat insulation performance and high temperature resistance. It can effectively isolate heat transfer in a high-temperature environment, has a certain flexibility, and is easy to be made into heat insulation pads of various shapes. It can prevent the temperature inside the rectangular seat 13 from being too high. The rectangular groove 133 is used to limit components such as the electric push rod 181 and the bellows 182. By rotating and opening the replenishment port 172, lubricating oil can be replenished into the oil storage box 17. The penetration block 171 is made of aerogel felt material. As a new type of heat insulation material, aerogel felt is a porous material with nano-scale pore size, which may have a slow penetration effect on oil molecules. Although it is mainly used for heat insulation, a similar porous structure may also affect oil penetration. It can slowly introduce the lubricating oil inside the oil storage box 17 to the outside of the screw rod 151. When there is a lot of rainwater storage and the sluice needs to be opened for flood discharge, the screw rod 151 is usually in a relatively hot environment, and most of the lubricating oil on it has evaporated, making it more difficult for the rotating shaft seat 15 to drive the screw rod 151 to move upward. Before opening the sluice, the electric push rod 181 is started to compress the bellows 182, and the air inside the bellows 182 is pressed into the oil storage box 17, thereby accelerating the influx of the lubricating oil in the oil storage box 17 into the penetration block 171, so that the penetration block 171 can temporarily extrude more lubricating oil to lubricate the screw rod 151. Subsequently, the T-shaped pipe 183 can be connected to the atmosphere by adjusting the air valve 184 from the outside, thereby driving the bellows 182 to deform and reset.

[0040] As Figure 1-5 shown, in this embodiment, a reinforcing plate 111 is fixedly connected to one side of the water isolation plate 11, a connecting seat 12 is fixedly connected to the top of the water isolation plate 11, the screw rod 151 passes through the connecting seat 12 and is fixedly connected to it. A plurality of ear plates 161 are fixedly connected to the front side of the U-shaped frame 16, a cross bar 162 is fixedly connected to one side of the ear plate 161, a plurality of limiting rods 163 are fixedly connected to the front side of the limiting frame 10, the limiting rods 163 pass through the adjacent cross bars 162 and are slidably connected to them, a spring 164 is fixedly connected between the cross bar 162 and the limiting rod 163, two arc-shaped plates 165 are fixedly connected to the bottom of the U-shaped frame 16, and a baffle 14 is fixedly connected between the two inner walls of the limiting frame 10.

[0041] During specific implementation, the overall support strength of the water barrier plate 11 is enhanced by the reinforcement plate 111. The connecting seat 12 is used to rotatably connect the screw rod 151 to the water barrier plate 11. When the screw rod 151 rotates, it moves upward, thereby driving the water barrier plate 11 to move upward through the connecting seat 12 to open the gate. The cross bar 162 is limited by the ear plate 161, and the sliding limit of the cross bar 162 is achieved by multiple limiting rods 163, realizing the overall horizontal sliding limit of the U-shaped frame 16. When the water barrier plate 11 moves upward, it contacts the arc plate 165, thereby driving the U-shaped frame 16 to move forward, stretching multiple springs 164, so that the U-shaped frame 16 can protect the screw rod 151 during normal gate closing. When the water barrier plate 11 moves upward, the U-shaped frame 16 will not block the water barrier plate 11. After the water barrier plate 11 moves downward, multiple springs 164 drive the U-shaped frame 16 to automatically move back to its original position.

[0042] Embodiment 2

[0043] On the basis of Embodiment 1, in order to remotely drive and manually drive the screw rod 151, it is convenient to deal with various emergencies during flood discharge.

[0044] As Figure 3 shown, in this embodiment, a turntable 152 is fixedly sleeved on the outer wall of the shaft seat 15, and a docking plate 153 is fixedly connected to the top of the top plate 131. The shaft seat 15 is rotatably connected to the docking plate 153. The driving module 19 includes a fixed seat 191 slidably connected to the top of the top plate 131. A second motor 193 is fixedly connected to the top of the fixed seat 191. A gear 194 is fixedly sleeved on the output end of the second motor 193. A toothed ring 195 is fixedly sleeved on the outer wall of the shaft seat 15. The toothed ring 195 meshes with the gear 194. A second electric push rod 192 and a protective shell 196 are fixedly connected to the top of the top plate 131. The output end of the second electric push rod 192 is fixedly connected to the fixed seat 191.

[0045] During specific implementation, when the protective shell 196 and its internal components are damaged for various reasons, the screw rod 151 can be rotated through the turntable 152. When it is necessary to automatically drive the shaft seat 15 to move the water barrier plate 11 upward, the second electric push rod 192 is started to drive the second motor 193 and the gear 194 to move, so that the gear 194 meshes with the toothed ring 195. The second motor 193 is started, and the shaft seat 15 is driven to rotate through the transmission of the gear 194 and the toothed ring 195, thereby driving the screw rod 151 to rotate, so that the water barrier plate 11 moves upward to open the gate. The protective shell 196 can protect its internal transmission components. When there is a power supply obstacle or the internal components of the protective shell 196 are damaged, the turntable 152 can be manually rotated to rotate the shaft seat 15.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0047] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
