Description

Technical Field

[0001] The utility model relates to the technical field of weir gates, and more specifically, to a prefabricated door frame component for a lower weir. Background Art

[0002] The lower opening weir gate is a kind of interception, regulation and backflow prevention equipment currently widely used in the middle interception well and terminal outlet of the combined sewer network. In the process flow, the rainwater and sewage diversion can be achieved by controlling the opening and closing of the lower opening weir gate. In the dry season, there is only sewage in the combined pipe, and the lower opening weir gate is closed to intercept the sewage, which flows to the sewage treatment plant through the sewage pipe for treatment. In the rainy season, the initial rainwater and the sewage in the pipe are intercepted and discharged into the sewage pipe. The middle and late rainwater is discharged downstream through the opened lower opening weir gate.

[0030] A support assembly is arranged on the outside of the prefabricated door frame body 1, and the support assembly includes two limit plates 7, an adjustment bracket and a connecting frame. The adjustment bracket is connected to the connecting frame through the limit plates 7. The connecting frame is used to adjust the distance between the two limit plates 7. The adjustment bracket is used to adjust the height to support the prefabricated door frame body 1 during installation.

[0031] When prefabricated door frame body 1 is pre-supported, the distance between two limit plates 7 is adjusted through the connecting frame so that the limit plates 7 are in contact with the side surfaces of prefabricated door frame body 1 to pre-support the prefabricated door frame body 1 and effectively improve the installation efficiency.

[0032] Furthermore, the limiting plate 7 includes two telescopic plates 8 , which are slidably installed in the inner cavity of the limiting plate 7 , and the telescopic plates 8 are located at the upper and lower ends of the limiting plate 7 .

[0033] In this embodiment, the implementation scenario is specifically as follows: the distance that the telescopic plate 8 extends out of the inner cavity of the limiting plate 7 is used to adjust the length of the limiting plate 7, thereby increasing the contact area between the limiting plate 7 and the side wall of the prefabricated door frame body 1, thereby improving the stability of the prefabricated door frame body 1 during pre-installation support.

[0034] Furthermore, the connecting frame includes a sleeve 4, a screw 5 and a mounting block 41. The mounting block 41 is connected to the screw 5 through the sleeve 4.

The outer ends of the screw 5 and the mounting block 41 are connected to a connecting plate 6. Two limit plates 7 are respectively connected to the mounting block 41 and the screw 5 through the connecting plate 6.

[0035] In this embodiment, the implementation scenario is specifically as follows: by rotating the sleeve 4 to adjust the length of the screw rod 5 extending out of the sleeve 4, the distance between the two limit plates 7 can be adjusted, so that the prefabricated door frame body 1 can be clamped conveniently.

[0036] Furthermore, the adjustment bracket includes a first support rod 9, a first adjustment cylinder 10, a second support rod 11 and a second adjustment cylinder 12.

The length of the second support rod 11 extending out of the second adjustment tube 12 is adjusted to achieve the adjustment of the length of the second support rod 11, increase the support points with the ground when supporting the prefabricated door frame body 1, and improve the stability of the prefabricated door frame body 1 during pre-installation.

[0038] Furthermore, a gripping block 13 is disposed at the bottom of each of the first adjusting cylinder 10 and the second adjusting cylinder 12 , and the gripping block 13 is rotatably connected to the first adjusting cylinder 10 and the second adjusting cylinder 12 , respectively.

[0039] In this embodiment, the implementation scenario is specifically as follows: the gripping block 13 is used to increase the resistance between the bottom of the first adjustment cylinder 10 and the second adjustment cylinder 12 and the ground, thereby improving the stability of the pre-support when the prefabricated door frame body 1 is installed.

[0040] Furthermore, a plurality of through holes 14 are provided on the surface of the limit plate 7, and the telescopic plate 8 is connected to the outside through the through holes 14. A spring is provided on the surface of the telescopic plate 8 corresponding to one of the through holes 14, and one end of the spring is connected to the limit block 15, and the limit block 15 is slidably connected to the through hole 14.
