Detailed Description

The present application is described in further detail below in conjunction with figures 1-3.

The embodiment of the application discloses a small-size water conservancy throttle gate structure. Referring to fig. 1, the small-sized water conservancy throttle gate structure includes a plate-shaped shutter 1 and a support frame 2 in the form of a gate. The support frame 2 comprises two vertically arranged support bars 21 and a cross beam 22 for connecting the two support bars 21. One of the two ends of the cross beam 22 in the length direction is fixedly connected to the top end of one of the support rods 21, and the other end is fixedly connected to the top end of the other support rod 21. The flashboard 1 is connected on the inner side of a door-shaped frame surrounded by two supporting rods 21 and a cross beam 22 in a sliding way. The cross beam 22 is connected with a screw rod 3 in vertical arrangement in a threaded manner, and the bottom end of the screw rod 3 is rotationally connected with the end face of the top end of the flashboard 1. When the screw 3 rotates, the screw 3 drives the shutter 1 to rise or fall in the vertical direction.

Referring to fig. 1 and 2, a plurality of auxiliary rods 31 are fixedly connected to the screw 3, the axis of the auxiliary rods 31 is arranged along the axis direction of the screw 3, and the plurality of auxiliary rods 31 are arranged at intervals along the circumferential direction of the screw 3, and in this embodiment, two auxiliary rods 31 are taken as an example. The impact assembly 4 for striking the auxiliary rod 31 is rotatably connected to the top end surface of the cross beam 22, and when the screw 3 and the cross beam 22 are difficult to rotate, the auxiliary rod 31 is struck by the impact assembly 4, so that looseness is generated between the screw 3 and the cross beam 22, and the screw 3 can rotate conveniently.

Referring to fig. 2, a rib plate 32 is welded and fixed between the auxiliary rod 31 and the screw 3, the rib plate 32 is horizontally disposed, and when the impact assembly 4 impacts the auxiliary rod 31, the rib plate 32 increases the connection strength between the auxiliary rod 31 and the screw 3, thereby reducing the damage of the auxiliary rod 31.

Referring to fig. 2, the impact assembly 4 includes a plurality of impact bars 41 and a ring-shaped connection plate 42, and the connection plate 42 is rotatably connected to the tip end surface of the cross beam 22 and is disposed coaxially with the screw 3. The number of impact bars 41 is the same as and one-to-one opposite to the number of auxiliary bars 31, and a plurality of impact bars 41 are spaced apart along the circumferential direction of the connecting disc 42. The bottom of the impact rod 41 is fixedly connected with the side wall of the connecting disc 42, the top of the impact rod 41 is higher than the auxiliary rod 31, and when the connecting disc 42 rotates, the impact rod 41 contacts with the auxiliary rod 31, so that impact is generated at the joint of the screw 3 and the cross beam 22.

Referring to fig. 2, a hand guard 43 is rotatably connected to the top end of the impact rod 41, the hand guard 43 is 1/4 spherical, and the height of the hand guard 43 is lower than that of the impact rod 41. A rotary drum 431 is fixedly connected between two sharp corner ends of the hand guard 43, the axial direction of the rotary drum 431 is arranged along the diameter direction of the hand guard 43, and two ends of the rotary drum 431 are communicated with the outside. The striking rod 41 penetrates the drum 431 so that the hand guard 43 is rotatably coupled to the striking rod 41.

Referring to fig. 2, a locking bolt 421 is screw-coupled to the connection disc 42, and a screw thread section of the locking bolt 421 penetrates the connection disc 42. When the locking bolt 421 is rotated and approaches the cross member 22, the locking bolt 421 is pressed against the cross member 22, thereby relatively fixing the connection disc 42 and the cross member 22 by friction.

Referring to fig. 3, the connection pad 42 is provided with an oil groove 422, and the oil groove 422 is disposed obliquely. The top end of the oil groove 422 communicates with the top end face of the land 42, and the bottom end of the oil groove 422 communicates with the side wall of the inner side of the land 42. Lubricating oil can enter the connection between the screw 3 and the cross beam 22 through the oil groove 422, thereby lubricating the screw 3 and the cross beam 22. A cover 423 is further screwed into the top opening of the oil groove 422, and the top opening of the oil groove 422 is blocked by the cover 423, so that water flowing into the screw 3 and the cross beam 22 from the oil groove 422 is reduced.

The implementation principle of the small water conservancy throttle gate structure is as follows: before the throttle is operated, the cover 423 is first screwed to separate the cover 423 from the oil groove 422, lubricating oil is dropped into the oil groove 422, and then the rotary drum 431 is held to strike the impact rod 41 against the auxiliary rod 31 by rotating the connecting disc 42, thereby vibrating and separating the screw 3 from the cross beam 22, and thus, the screw 3 and the cross beam 22 are relatively rotated.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
