Description

Technical Field

[0001] The utility model relates to the technical field of weir gates, and more specifically, to a hydraulically operated downward-opening weir gate panel. Background Art

[0002] In the field of water conservancy projects, downward-opening weir gates, as a crucial water flow control device, play a vital role. Such devices are often installed at the outlet of the water flow channel to achieve effective regulation of the water flow. The core function of the downward-opening weir gate lies in its excellent water flow regulation ability. By precisely controlling the opening degree of the weir gate, the water flow in the drainage system can be flexibly adjusted to meet various actual needs and complex working conditions.

[0003] For a downward-opening weir gate disclosed in Chinese Patent CN115288280A, during actual operation, its panel can move back and forth relative to the driving device. Although this design achieves effective regulation of the water flow to a certain extent, it also brings a problem: the joint between the panel and the weir gate frame is prone to deformation under continuous impact, which gradually leads to a deterioration of the sealing effect. This deformation not only affects the overall performance and service life of the weir gate but also may pose a potential threat to the safe and stable operation of the water conservancy project.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the drawings and embodiments:

[0023] As shown Figures 1-4 in the figure, a hydraulic bottom-opening weir gate panel includes a central plate 1. Installation cylinders 4 are provided on both sides of the central plate. The installation of the installation cylinders increases the overall strength of the panel and improves its durability. Guide plates 7 are provided on both sides of the installation cylinders. The guide plates can cooperate with the weir gate frame for guiding. The design of the guide plates makes the movement of the panel more stable, reducing friction and wear. A sealing plate 44 is provided at the bottom of the installation cylinder. A hinge seat 48 is provided on the sealing plate. A number of reinforcing plates 5 are provided on the central plate. The setting of the reinforcing plates improves the overall load-bearing capacity of the panel, making it more firm and durable. Top plates 2 and bottom plates 3 are provided on the upper and lower sides of the central plate respectively. The setting of the top plates and bottom plates not only improves the appearance quality of the panel, but also further enhances its structural strength.

[0024] Further, an installation hole 481 is provided on the hinge seat. The design of the installation hole enables the telescopic rod of the hydraulic cylinder to be firmly connected to the hinge seat, ensuring the stable movement of the panel.

[0025] Further, a lifting ring 6 is installed on the reinforcing plate. The setting of the lifting ring makes the installation and maintenance of the panel more convenient and fast, improving work efficiency.

[0026] In at least one embodiment, the installation cylinder includes a back plate 42. Left plates 41 and right plates 43 are respectively provided on both sides of the back plate. The left plate is connected with a left connecting plate 45, and the right plate is connected with a right connecting plate 47. A front plate 46 is provided between the left connecting plate and the right connecting plate. The complex structure of the installation cylinder improves the overall stability and load-bearing capacity of the panel, enabling it to adapt to harsher working environments.

[0027] Further, the left plate 41 and the right plate 43 are perpendicular to the back plate.

[0028] Further, the front plate is parallel to the back plate.

[0029] In a refined solution, an installation cavity for the telescopic rod of the hydraulic cylinder to insert is formed in the installation cylinder, and a hinge seat 48 is provided at the bottom of the installation cavity.

[0030] In at least one embodiment, the reinforcing plate includes a first plate 52, a second plate 51 and a third plate 53. The first plate and the third plate are connected together through the second plate. The first plate and the third plate are welded to the central plate. The complex structure of the reinforcing plate improves the overall strength and stiffness of the panel, making it more durable.

[0031] Further, both sides of the reinforcing plate are welded to the installation cylinder. The welded connection between the reinforcing plate and the installation cylinder improves the overall load-bearing capacity of the panel, making it more stable.

[0032] In some embodiments, the reinforcing plate may be formed by bending a whole iron plate. The reinforcing plate formed by bending a whole iron plate reduces the processing steps and material waste, and improves the production efficiency.

[0033] Further, the second plate is arranged parallel to the center plate. The second plate arranged parallel to the center plate improves the supporting effect of the reinforcing plate on the center plate and enhances the overall strength of the door panel.
