Description

Technical Field

[0001] The utility model relates to the technical field of gates, and more specifically, to a detachable flat steel gate. Background Art

[0002] Steel gates are usually movable structures used to open and close the water inlets of local hydraulic structures. They can regulate flow, control water levels, and transport ships. They have the characteristics of low manufacturing difficulty, simple installation, low cost, high degree of mechanization, wide application range, and good water-blocking effect.

[0003] With the extensive development of hydraulic structures, the functional requirements are becoming more and more diversified, and the structural requirements for steel gates are also changing. The drainage working well is connected to the open sea. The seawater level in the working well changes with the tide, which affects the dry land construction of the drainage box culvert structure connected to it. It is necessary to set a water-retaining steel gate in the drainage working well structure. After the drainage box culvert is completed, some seawater needs to be introduced for relevant water-closing experiments, structural flushing and other operations.

[0004] However, currently existing gates generally adopt an integral structure, which means that after the gates are installed, seawater regulation cannot be achieved, resulting in on-site cutting, resulting in poor cutting surface quality, greater safety hazards in operation, and difficulty in subsequent repeated closure. Utility Model Content

[0005] The utility model provides a detachable flat steel gate to solve the problem that the existing fixed gate needs to be cut later, which causes construction difficulties.

[0006] According to one aspect of the utility model, a detachable flat steel gate is provided, comprising a rectangular steel frame, a lower welded cover of the steel frame is provided with a stainless steel plate, a window is provided on the upper portion of the steel frame, and guide channel steels are provided on both sides of the steel frame, a sealing groove is provided on the periphery of the window, and a bracket is provided on the steel frame near the window side; a detachable cover is engaged with the bracket and the guide channel steel, a sealing ring is provided on the inner side of the detachable cover, a protrusion adapted to the sealing groove is provided on the sealing ring, and a lifting ear is provided on the top of the detachable cover.

[0007] Preferably, based on the above scheme, the steel frame is formed by welding steel sections, and support beams are arranged between the steel frames, and the support beams are multiple and supported at intervals in the steel frame.

[0008] Preferably, based on the above solution, a reinforcing beam is provided on the upper portion of the window, and a plurality of columns are provided between the reinforcing beam and the steel frame.

[0009] Preferably, based on the above solution, a plurality of expansion screws arranged at intervals are installed on the inner side of the steel frame.

[0010] Preferably, based on the above solution, the sealing ring is a water-stopping rubber pad.

[0011] The utility model discloses a detachable flat steel gate, which adopts a steel frame structure and is provided with brackets on the steel frame. The detachable cover can be limited in the window through the structural design of the brackets and the guide grooves, and the sealing groove on the window is combined with the sealing ring on the detachable cover to achieve sealing between the detachable cover and the window when water is stopped. When sealing is not needed, the detachable cover can be slid outward along the guide groove through the lifting ear on the top to achieve rapid withdrawal and use the window for flood discharge. The overall structure can be prepared in advance without on-site cutting, and the operation is convenient and stable, with low construction difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1 , and combined with Figure 2 , Figure 3 and Figure 5 As shown, the utility model is a detachable flat steel gate, including a rectangular steel frame 1, which is welded by channel steel or rectangular steel pipe. In order to ensure the strength of the steel frame 1, a support beam 11 is usually installed on the inner side of the steel frame 1. A plurality of support beams 11 can be designed according to the height or length of the steel frame 1, and the support beams 11 are supported on the inner side of the steel frame 1 at intervals.

[0028] The upper cover of the steel frame 1 is provided with a stainless steel plate 2 for sealing, and a window 3 is provided on the upper part of the steel frame 1. The window 3 is generally rectangular. Guide channel steels 4 are provided on both sides of the steel frame 1. A sealing groove 5 is provided around the window 3. A bracket 6 is provided on the side of the steel frame 1 near the window 3. A detachable cover 7 is detachably installed in the bracket 6 and the guide groove.

[0029] When in use, the steel frame 1 is fixed as a whole to the cement piers on both sides of the gate by the expansion screw 13 to achieve its fixation. When water is injected, the disassembly cover 7 is pressed on the steel frame 1 due to the force of the water pressure. At this time, the protrusion 9 on the sealing ring 8 is engaged in the sealing groove 5, so as to achieve the sealing connection between the disassembly cover 7 and the steel frame 1 to prevent water leakage. When the disassembly cover 7 is not needed, the top winch can be combined with the wire rope and the hook to be hung on the lifting ear 10, and the disassembly cover 7 can be moved upward along the guide channel steel 4, so as to achieve its rapid disassembly. During the whole operation, no manual high-level operation is required, and it is convenient and quick to use. Preferably, the sealing ring is a water-stopping rubber pad.

[0030] Specifically, the steel frame 1 of the utility model is welded by steel sections, and support beams 11 are arranged between the steel frames 1. There are multiple support beams 11 and they are supported in the steel frame at intervals to ensure the strength of the steel frame 1. Furthermore, a reinforcing beam 12 is arranged on the upper part of the window 3, and a plurality of columns are arranged between the reinforcing beam 12 and the steel frame 1 at intervals.

[0031] The utility model discloses a detachable flat steel gate, which adopts a steel frame 1 structure. A bracket 6 is arranged on the steel frame 1. Through the structural design of the bracket 6 and the guide groove, the detachable cover 7 can be limited in the window 3, and the sealing groove 5 on the window 3 is combined with the sealing ring on the detachable cover 7 to achieve sealing between the detachable cover 7 and the window 3 when water is stopped. When sealing is not needed, the detachable cover 7 can be slid outward along the guide groove through the lifting ear 10 on the top to achieve its rapid withdrawal, and the window 3 is used for flood discharge. The overall structure can be prepared in advance without on-site cutting, and the operation is convenient and stable, and the construction difficulty is small.

[0032] Finally, the method of this application is only a preferred implementation scheme and is not intended to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
