Description

Technical Field

[0001] The utility model relates to the technical field of flood discharge sluice devices, in particular to a lifting flood discharge sluice device. Background Technique

[0002] Flood discharge means that in the case of heavy rainfall or snowmelt, etc., the excess water volume of the reservoir is quickly discharged through special equipment to prevent the reservoir from exceeding the water level and avoid serious disasters such as water overflowing, the collapse of the reservoir dam or dike. As an important part of water conservancy facilities, the flood discharge sluice can not only intercept the water flow, control the water level, but also regulate the flow rate, discharge sediment and floating debris, etc., so as to ensure the safety of the reservoir and the surrounding environment. With the frequent occurrence of extreme weather events caused by climate change, the effectiveness of reservoir management and flood discharge measures is particularly important.

[0003] The patent with the publication number CN112176958A discloses an adjustable flood discharge gate for water conservancy projects, including an installation frame and a gate plate. Sliders are arranged on both sides of the gate plate, and the sliders are slidably matched with the guide grooves arranged on the installation frame. An elevation driving assembly is also arranged on the installation frame, and the elevation driving assembly is connected to the gate plate; a bottom groove is arranged at the bottom of the installation frame, a bottom plate is slidably installed inside the bottom groove, one side of the bottom plate facing the gate plate penetrates through the bottom groove, and embedded grooves are also arranged on both sides of the installation frame. A pressing plate is slid inside the embedded groove, and the pressing plate is also connected to the bottom plate through a linkage assembly. By setting the elevation driving mechanism to drive the opening and closing control of the gate plate relative to the installation frame, and when the gate plate moves towards the bottom plate and generates a squeezing force on the bottom plate, the bottom plate moves downward, and drives the pressing plates arranged on both sides of the installation frame to move towards the gate plate through the linkage assembly, thereby improving the sealing performance after the gate plate is closed.

[0004] Although the above-mentioned prior art improves the sealing performance after the gate plate is closed to a certain extent and avoids the problem of water leakage during flood discharge. However, since the device uses a frequent lifting mechanism to adjust the opening and closing of the gate, this is likely to cause wear of the gate during long-term use, thereby reducing its service life. In addition, during daily small-discharge flood discharge operations, frequent lifting actions will also consume a large amount of energy, affecting the economy and efficiency of the overall work. In view of this, we propose a lifting flood discharge sluice device. Content of the Utility Model

Guide rails 10 are provided on both the left and right sides of the inner wall of the installation frame 1. A fixed top plate 2 is provided at the top of the installation frame 1.

[0038] Further, a first motor 303 is provided on the right side of the first drive box 300. The first motor 303 operates with an external power supply. The output shaft of the first motor 303 is coaxially connected to the right end of the first rotating shaft 301, and the first rotating shaft 301 is driven to rotate forward and backward by the first motor 303.

The two positioning rods 11 respectively pass through the two positioning holes 323, and the gate 32 is slidably connected to the outside of the positioning rods 11, further improving the stability of the gate 32.

[0041] Further, the second traction assembly 40 includes a second drive box 400 with an open top structure. Second mounting plates 404 are provided at the tops of the front and rear sides of the second drive box 400. The second mounting plates 404 are detachably connected to the bottom of the fixed top plate 2 by screws, so that the second drive box 400 is fixed to the bottom of the fixed top plate 2. A wire passing hole b4000 for the second traction rope 41 to pass through is formed in the middle of the bottom of the second drive box 400.

[0042] Further, a second rotating shaft 401 is rotatably connected between the left and right sides of the inner wall of the second drive box 400. A second wire winding wheel 402 is provided on the outer wall of the second rotating shaft 401. The second traction rope 41 is wound around the second wire winding wheel 402. The second wire winding wheel 402 is driven to rotate by the second rotating shaft 401, so as to wind or unwind the second traction rope 41.

[0043] Further, a second motor 403 is provided on the right side of the second drive box 400. The second motor 403 operates with an external power supply. The output shaft of the second motor 403 is coaxially connected to the right end of the second rotating shaft 401, and the second rotating shaft 401 is driven to rotate forward and backward by the second motor 403.

[0044] Furthermore, a second lifting ring 420 is provided in the middle of the top of the hollow baffle 42.

Mounting holes 4300 are formed in the third mounting plates 430. Bolts 44 are connected in the mounting holes 4300. The threaded ends of the bolts 44 are threadedly connected to the thread grooves 422. Since the weight of the hollow baffle 42 is reduced, different depths of flood discharge can be adapted by equipping counterweights 43 of different weights.

[0045] When the lifting type flood discharge gate device of this embodiment is in use, first, the mounting frame 1 is fixed at a designated position to ensure its stability. The first drive box 300 is fixed to the top of the fixed top plate 2 by screws, and the second drive box 400 is fixed to the bottom of the fixed top plate 2. The first towing rope 31 of the first towing assembly 30 is connected to the first lifting ring 322 of the gate plate 32, and it is ensured that the two towing ropes 31 pass smoothly through the wire passing holes a20 on the fixed top plate 2 without entanglement. Similarly, the second towing rope 41 of the second towing assembly 40 is connected to the second lifting ring 420 of the hollow baffle 42 and correctly passes through the wire passing hole b4000. During large flow flood discharge operation, the first motor 303 is started to drive the first rotating shaft 301 to rotate, thereby driving the first towing rope 31 to perform a wire winding operation, so that the gate plate 32 rises along the guide rail 10 to open the flood discharge channel and realize large flow flood discharge. When the flood discharge is completed, the gate plate 32 is slowly lowered through a wire releasing operation until the flood discharge channel is completely closed to achieve the purpose of intercepting the flow. During small flow flood discharge operation, the second motor 403 is started to drive the second rotating shaft 401 to rotate, thereby tightening the second towing rope 41, so that the hollow baffle 42 and the counterweight 43 rise along the rectangular groove 320 to open a part of the flood discharge port 321 for small-scale flood discharge. After completion, the hollow baffle 42 and the counterweight 43 are lowered through a wire releasing operation to close the flood discharge port 321 to achieve flow interception. By adopting a hierarchical adjustment method, the frequent lifting actions of the gate plate 32 are reduced, the energy consumption is lowered, and the economy and efficiency of the equipment operation are improved.
