Detailed Description

The technical scheme of the utility model is clearly and completely described below with reference to the accompanying drawings and the specific embodiments. The specific matters listed in the following examples are not limited to the technical features necessary for solving the technical problems of the technical solutions described in the claims. Meanwhile, the list is only a part of embodiments of the present utility model, but not all embodiments.

The driving mechanism is used for the horizontal rotary sluice, one side of the sluice is hinged to the side retaining wall or the pier column through the rotating shaft, and the driving mechanism controls the sluice to open and close through driving the sluice to rotate around the rotating shaft. Taking the single-leaf gate shown in fig. 1-3 as an example, the drive mechanism includes a support assembly 2, a drive assembly 3, and a slider assembly 4. The support assembly 2 in the illustrated embodiment is a link having one end pivotally connected to the gate and the other end pivotally connected to the slider assembly 4. The driving assembly 3 adopts a hydraulic cylinder, the cylinder body of the hydraulic cylinder is a power part 301, and the power part can be arranged on a fixed plate above the gate or on a pier stud, and the setting position is higher than the gate and the water level line. The cylinder rod of the hydraulic cylinder is a driving portion 302 which extends vertically downward and is connected to the slider assembly 4. The cylinder rod of the hydraulic cylinder stretches and contracts to drive the sliding block assembly 4 to move up and down, and the sliding block assembly 4 moves by driving one end of the supporting assembly 2, so that the supporting assembly 2 rotates around a hinge point of the supporting assembly and the gate 1. The deflection of the supporting component 2 changes the extending length in the horizontal direction, when the horizontal length is increased, the gate 1 can be pushed to horizontally rotate around the rotating shaft 101 on the side surface to close the gate, and when the horizontal length is reduced, the gate is controlled to open.

In the embodiment of fig. 1-3, the retaining wall 6 on the side of the gate is provided with a guide mechanism for limiting the direction of movement of the slide assembly 4. The guide mechanism shown in the figures is in the form of a chute in which a portion of the slider assembly 4 is disposed, thereby limiting its movement to both sides so that it can withstand the opposing forces of the support assembly 2. The guide mechanism may also take the form of a rail or other structure, as desired. The specific structure of the slider assembly 4 is determined by the need and the form of the guiding mechanism, and may be a slider, a connecting shaft or other forms, for example, a roller is arranged on a connecting structure to match with the sliding groove.

Fig. 3-5 show two gates in opposite directions, which are respectively located at two sides of the pier column and are rotatably connected with the pier column through respective rotating shafts. The two gates are respectively connected with a supporting component 2, a driving component 3 and a sliding block component 4 are arranged between the two gates, and the two gates are shared. The driving component 3 controls the sliding block component 4 to act so as to drive the two gates to open and close synchronously. Also, a guide mechanism may be provided on abutment 7 to limit movement of slider assembly 4. In this embodiment, the left and right support assemblies 2 are counter-symmetrical, and the lateral forces acting on the slide assemblies 4 can cancel each other out, so that the drive assembly 3 or the guide mechanism does not have to take up excessive forces. In addition, by setting the positions of the slide block assemblies 4 after the two gates are closed, the acting forces of the two side support assemblies 2 are opposite in direction (for example, the two groups of support assemblies are parallel and opposite), so that the mutual locking can be realized in the gate closing state, and the hydraulic cylinder can release pressure at the moment and does not bear load.

Fig. 7 shows a sluice embodiment of a multi-leaf sluice, wherein the two-leaf sluice shown in fig. 6 is used as a group, multiple groups are arranged continuously along the width direction of the sluice, and after the sluice is closed, the two adjacent groups of sluice are connected, so that the sluice can be suitable for wider sluice.

Fig. 8 shows another embodiment of the slide block assembly and its guiding mechanism, in which a driving rod 8 is connected to the cylinder rod of the hydraulic cylinder, and the driving rod 8 may be connected to the cylinder rod in an integral structure, or may be connected by a universal joint or the like. The driving rod 8 extends vertically downwards and is fixedly connected with the slider assembly 4. A sliding sleeve 9 is fixed on the retaining wall or the pier column 7, and a driving rod 8 is arranged in the sliding sleeve 9 in a penetrating way and can only move along the up-down direction. In this embodiment, the cooperating structure of the driving rod 8 and the sliding sleeve 9 constitutes a guiding mechanism for limiting the up-and-down movement of the slider assembly 4.

In one embodiment, not shown, the drive assembly may be a motor or hydraulic motor in combination with a screw, which may be a powered part, and may be disposed in a relatively dry area above the gate. The screw extends downward as a driving portion, and the slider assembly has an internal thread therein which mates with the screw. When the motor or the hydraulic motor drives the screw rod to rotate, the sliding block component is limited by the supporting component 2 or the guiding mechanism connected with the sliding block component and cannot rotate, so that the sliding block component can move up and down along the screw rod to drive the supporting component 2 to control the gate to open and close. For this structural mode, the guiding mechanism may take the form of a chute, a guide rail, etc., or may refer to the embodiment shown in fig. 8, where a sleeve is disposed on a retaining wall or pier to limit the lateral movement of the screw, and the screw and the sleeve cooperate to form a guiding mechanism for limiting the up-and-down movement of the slider assembly.

The support members 2 for controlling the opening and closing of the shutter may be arranged in one or two groups in the vertical direction, or may be arranged in more groups. When two or more groups are arranged, each group of support assemblies 2 is correspondingly connected with a sliding block assembly 4, and the plurality of sliding block assemblies 4 are distributed in the vertical direction and are driven by the driving assembly 3 to move up and down.

The above description of the specific embodiments is only for aiding in understanding the technical concept of the present utility model and its core idea, and although the technical solution has been described and illustrated using specific preferred embodiments, it should not be construed as limiting the present utility model itself. Workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit of the technology. Such modifications and substitutions are intended to be included within the scope of the present utility model.
