Problems solved by technology

[0002] For the inspection gates of hydropower or water conservancy projects, considering the maintenance needs, an inspection gate is usually set in front of it. For the inspection gate with a small orifice with a high water head, although the gate size is small, the water pressure is large, and the thickness of the steel plate will increase. It is thicker, adopts the traditional welding gate structure, the welding space is narrow, the workers are difficult to operate, the welding quality is difficult to guarantee, the manufacturing is difficult, and the conventional water seal wears a lot, is easy to damage, and the opening and closing capacity is also large, so the existing There are still deficiencies in the technology and need to be further improved

Embodiment

[0035] The small orifice integral casting type flat fixed wheel maintenance gate in this example is as follows: Figures 1 to 3 As shown, a cast door body formed by a single casting is used. The casting door body 10 is cast with a top water seal installation groove 12, a bottom water seal installation groove 15, a longitudinal beam 16, a cross beam 17, a triangular through hole 18, an open cavity 19, a closed cavity 20, and a longitudinal guide hole. 21. Structures such as lateral guide holes 22, fixed wheel mounting holes 23, lateral sliders 24, and hanging holes 27.

[0036] like figure 2 As shown, the longitudinal beams 16 located on both sides of the casting door body 10 are used as side beams, and the upper and lower parts of the side beams are symmetrically provided with two fixed wheel mounting holes 23 in the center position; the fixed wheel mounting holes 23 are rounded inside; Figure 7 As shown, there is a fixed wheel assembly 50 in the fixed wheel installation h...

Abstract

The invention discloses a small-orifice integral casting type plane fixed wheel bulkhead gate. The small-orifice integral casting type plane fixed wheel bulkhead gate comprises a casting door body (10). A top side water seal mounting groove (12) is formed in the downstream surface of the casting door body, the cross section of the top side water seal mounting groove is in a rectangular shape, andthe top side water seal mounting groove is internally provided with a top side water seal assembly (30). The top side water seal assembly includes a steel-based sliding block (31) and a rubber pad (32). The steel-based sliding block and the rubber pad are fixed into the top side water seal mounting groove by a set of countersunk screws (33). A bottom water seal mounting groove (15) is formed in the bottom surface of the casting door body, and the bottom water seal mounting groove is internally provided with a bottom water seal assembly (40). A bottom water seal (41) in the bottom water seal mounting groove is fixed into the bottom water seal mounting groove through a bottom water seal pressing plate (42) and a set of countersunk screws. The bottom water seal and the rubber pad in the top side water seal assembly are tightly connected at both ends. The small-orifice integral casting type plane fixed wheel bulkhead gate can effectively guarantee the water stopping effect of the bulkheadgate under a special high water head.

Description

technical field [0001] The invention relates to a small orifice integral casting type plane fixed wheel maintenance gate, which belongs to the technical field of metal structures of water conservancy and hydropower engineering. Background technique [0002] For the maintenance gate of hydropower or water conservancy projects, considering the maintenance needs, an maintenance gate is usually set in front of it. For the small orifice plane maintenance gate with high water head, although the size of the gate is small, the water pressure is large, and the thickness of the steel plate will be reduced. It is thicker, adopts the traditional welding gate structure, the welding space is small, the workers are difficult to operate, the welding quality is difficult to guarantee, the manufacturing is difficult, and the conventional water seal has a large amount of wear and is easily damaged, and the opening and closing capacity is also large, so the existing The technology still has def...
