Description

Technical Field

[0001] The utility model relates to the field of steel gates, in particular to an efficient sealing steel gate for water conservancy projects. Background Technique

[0002] The installation method of the steel gate for water conservancy projects is as follows: Before installation, first complete the construction of basic structures such as the gate slot, and then use equipment such as a crane to lift the entire steel gate at one time and place it in the predetermined position; for large or heavy steel gates, they are usually manufactured and transported in sections, and then installed in sections on site; The working principle of the steel gate for water conservancy projects is: By controlling the opening and closing of the gate, the flow rate and water level of the water flow are adjusted; Taking the flat gate as an example, the water flow is usually controlled by vertical lifting; When the gate rises, the water flow can pass freely; When the gate descends, the water flow is blocked;

[0003] When the steel gate is under the action of large water pressure or external force, the connection between the steel gate and the sealing track will deform, resulting in gaps in the originally well-sealed parts; thereby destroying the seal; leading to water leakage in the steel gate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-6 , the present utility model provides an efficient sealing steel gate for water conservancy projects, including a gate body 1. A flood discharge channel 6 is opened in the middle of the gate body 1, and a first sealing frame 3 is fixedly installed at the front of the flood discharge channel 6. At the same time, a diversion pipe 2 is fixedly installed at the rear of the flood discharge channel 6. And connecting columns 10 are fixedly welded on both sides of the surface of the gate body 1. One end of the connecting column 10 away from the gate body 1 is fixedly welded to the top frame 11. A screw rod 12 is movably installed in the middle of the top frame 11. At the same time, the bottom of the screw rod 12 is movably connected to the surface of a connecting plate 71 through a pin shaft. One end of the connecting plate 71 is fixedly installed with a front door plate 8, and the other end of the connecting plate 71 is fixedly installed with a rear door plate 7.

[0021] Working principle: When in use, install this device in the flood discharge area of the pond dam. When it is necessary to intercept the flow of the pond dam, at this time, the screw rod 12 is driven to rotate, so that the connecting plate 71 moves downward, so that the rear door plate 7 and the front door plate 8 move downward synchronously. The downward movement of the rear door plate 7 intercepts the flood discharge channel 6 once through the rubber ring 4; the rear door plate 7 moves downward through the insertion port 13 and is inserted into the sealing groove 14 to intercept the flood discharge channel 6 twice; the method of intercepting and sealing with two groups of door plates is used to replace the traditional method of using a single group of valves for intercepting. The two gate plates cooperate with each other and can form a double sealing line when closed, effectively reducing the possibility of water leakage; the front door plate 8 is used as the main seal, and the rear door plate 7 is used as the auxiliary seal, greatly improving the overall sealing effect of the steel gate.

[0022] As a preferred embodiment, an insertion port 13 is opened on the top surface of the gate body 1, and a sealing groove 14 is opened inside the gate body 1. At the same time, the sealing groove 14 and the insertion port 13 are communicated, and the widths of the sealing groove 14 and the insertion port 13 are the same.

[0023] The insertion port 13 is adapted to the size of the rear door plate 7, and the rear door plate 7 moves downward through the insertion port 13 and is inserted into the sealing groove 14 to block the flood discharge channel 6 once.

[0024] A gasket can be fixedly installed on the outer surface of the rear door panel 7. When inserted into the inner part of the sealing groove 14, it can seal the gap between the rear door panel 7 and the sealing groove 14, improving the sealing performance when the rear door panel 7 is in the closed state. When the front door panel 8 and the rear door panel 7 move downward and intercept the water body in the flood discharge channel 6, the front door panel 8 can first obstruct the water flow, reducing the impact force of the water flow on the rear door panel 7, reducing the water pressure on the surface of the rear door panel 7, and avoiding deformation at the connection position between the rear door panel 7 and the sealing groove 14, so as to prevent the occurrence of gaps in the originally well-sealed part.

[0025] As a preferred embodiment, the first sealing frame 3 is annularly arranged, and a rubber ring 4 is fixedly installed on the surface of the first sealing frame 3. At the same time, the axial cross-section of the rubber ring 4, the first sealing frame 3, and the diversion pipe 2 is a concentric circle structure, and a limit clamping seat 5 is fixedly arranged at the bottom of the first sealing frame 3.

[0026] As Figures 1-4 shown: A slot 51 adapted to the size of the front door panel 8 is opened inside the limit clamping seat 5. The front door panel 8 moves downward to cover the outside of the first sealing frame 3 and is sealed by the rubber ring 4 to form a structure for secondary blocking of the flood discharge channel 6. At the same time, the bottom of the front door panel 8 is inserted into the slot 51.

[0027] As a preferred embodiment, the rear door panel 7, the connecting plate 71, and the front door panel 8 are combined to form a "U" - shaped structure, and the lengths of the rear door panel 7 and the front door panel 8 are the same. At the same time, two groups of reinforcing ribs 9 are fixedly installed on the outer sides of the rear door panel 7 and the front door panel 8, and the reinforcing ribs 9 are "U" - shaped.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
