Embodiment Construction

[0031] The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] Such as figure 1 and 2 As shown, the integral horizontal swivel dam includes a retaining dam body 1, a plurality of connecting rotating rods 2 and a driving device. The retaining dam body 1 is arranged above the dam foundation 5 and extends along the width direction of the river channel. The retaining dam body 1 The specific length is determined according to the width of the river. Multi...

Abstract

The embodiment of the invention discloses an integral horizontal rotary dam and relates to the field of water conservancy projects. The integral horizontal rotary dam comprises a retaining dam body, aplurality of connecting rotary rods and a driving device. The retaining dam body is arranged above a dam base and stretches along the width direction of a riverway, the connecting rotary rods are arranged in a spaced manner along the width direction of the riverway, one ends of the connecting rotary rods are hinged to one side of the retaining dam body and the other ends of the connecting rotaryrods are separately hinged to a plurality of supports pre-buried on the dam base correspondingly one by one; and the driving device is connected to the retaining dam body. The integral horizontal rotary dam not only overcomes defects that a rubber dam is easy to damage and age, long in dam lifting and collapsing time, low in safety, poor in reliability, short in service life and the like, but alsosolves the problems that a hydraulic dam side stops and leaks water, a hydraulic cylinder and an oil pipe are failed easily in the riverway and are hard to overhaul and the like, and also overcomes the defects that a conventional steel dam gate is clumsy in bed shaft, unscientific in stress, poor in sand washover effect, high in cost and the like.

Description

technical field [0001] The embodiments of the present invention relate to the field of water conservancy engineering, and in particular to an integral horizontal swivel dam. Background technique [0002] At present, the dam bodies that are widely used in the construction of water conservancy projects include rubber dams, hydraulic dams, and steel dam gates. [0003] The rubber dam is a kind of dam body that was widely used in the early days. It does not block water after the dam is released, and the cost is low, but there are many problems, mainly including: easy to damage, easy to age, long time to rise and collapse, and When the sediment is buried, manual cleaning is required, and the service life is short. [0004] At present, hydraulic dams are widely used in the market and have various forms. The basic features include that the panels are assembled structures, and each panel is about 6-12 meters wide; there is a side water-stop rubber between the panels; each panel is ...
