Description

Technical Field

[0001] The utility model relates to the technical field of movable dams, in particular to a detachable hydraulic movable dam. Background Art

[0002] A movable dam refers to a hydraulic structure with a dam body that can be raised and lowered and has the functions of storing water and discharging flood water. Existing hydraulic movable dams usually include gates, hinged supports, and hydraulic lifting devices. When manufacturing existing hydraulic movable dams, gates and ground axle frames are mostly welded together on hinged supports, and a hinged support water-stopping mechanism needs to be manufactured after manufacturing. The process is cumbersome, labor-intensive, and material-intensive, and it cannot be disassembled, making the movable dam difficult to inspect and repair, and prone to support hazards. In severe cases, the dam cannot be lowered during flood discharge, causing accidents. Therefore, it is necessary to design a detachable hydraulic movable dam that can quickly disassemble the hinged support and the gate. Utility Model Content

[0003] The utility model aims to provide a detachable hydraulic movable dam, which solves the problem that the hinge support and the gate of the existing movable dam cannot be disassembled.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] A detachable hydraulic movable dam comprises a gate, a hinge support and a hydraulic lifting device. The gate is provided with a hinge support connecting groove, a connecting piece is arranged in the hinge support connecting groove, and the hinge support is detachably connected through the connecting piece.

[0006] Furthermore, a ground axis is provided at the bottom of the gate, a second ear seat is welded on the axial position of the ground axis and in the connecting groove of the hinge support, a first ear seat extending out of the hinge support body is provided on the hinge support, and the connecting piece is a pin shaft, which is used to pass through the first ear seat and the second ear seat so that the gate and the hinge support can be detachably connected.

[0007] Furthermore, a clearance space is reserved in the connecting groove of the hinge support for installation and removal of the pin shaft.

[0008] Furthermore, the hydraulic lifting device includes a hydraulic telescopic rod, a third ear seat is arranged on the hinge support, a fourth ear seat is arranged on the back water surface of the upper end of the gate, the upper end of the hydraulic telescopic rod is hinged to the fourth ear seat, and the lower end is hinged to the third ear seat, and the hydraulic telescopic rod is used for lifting and lowering the gate.

[0009] Furthermore, a water guide eaves is arranged at the upper end of the gate.

[0010] The beneficial effects of the utility model are: (1) the gate of the hydraulic movable dam is detachably connected to the hinge support, rather than being welded as in the conventional hydraulic movable dam, so that the gate of the hydraulic movable dam can be quickly separated from the hinge support when the hydraulic movable dam needs to be overhauled.

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] like Figure 1-5 As shown, a detachable hydraulic movable dam includes a gate 1, a hinge support 2 and a hydraulic lifting device. The gate 1 is provided with a hinge support connecting groove 5, and a connecting piece is arranged in the hinge support connecting groove 5, and the hinge support 2 is detachably connected through the connecting piece.

[0020] Working principle: The gate 1 is the dam body of a movable dam, preferably with an arc-shaped dam surface, wherein the convex surface is near the water surface. The hydraulic lifting device is usually arranged on the concave surface of the arc-shaped dam surface, that is, the back water surface, to reduce the immersion of the hinge support 2 and the gate 1 in the water flow at the connection point. The hydraulic lifting device can not only be used to support the gate 1, but also to control the lifting and lowering of the gate 1. Since a connecting piece that can be detachably connected to the hinge support 2 is provided in the hinge support connecting groove 5, the hinge support 2 and the gate 1 can be quickly disassembled and installed through the connecting piece.

[0021] Preferably, a ground axis 4 is provided at the bottom of the gate 1, and a second ear seat 7 is welded on the axial position of the ground axis 4 and in the hinge support connecting groove 5. The hinge support 2 is provided with a first ear seat 6 extending out of the outside of the hinge support 2 body, and the connecting piece is a pin shaft 3. The pin shaft 3 is used to pass through the first ear seat 6 and the second ear seat 7, so that the gate 1 and the hinge support 2 can be detachably connected, and the first ear seat 6 extends out of the outside of the hinge support 2 body so that the hinge support 2 can be installed into the ground axis 4. The pin shaft 3 can be set as a threaded rod with a nut, and the threaded rod is threadedly matched with the nut. The ear holes of the first ear seat 6 and the second ear seat 7 are preferably able to be in close contact with the pin shaft 3, and the threaded rod is passed through the first ear seat 6 and the second ear seat 7, and clamped by the nut, so that the gate 1 is hinged to the hinge support 2. When the hinge support 2 needs to be disassembled, it is only necessary to lift the gate 1, loosen the nut, and pull out the threaded rod.

[0022] Preferably, a clearance space is reserved in the groove of the hinge support connecting groove 5 for the installation and disassembly of the pin shaft 3. Since the pin shaft 3 itself needs to have a certain length to pass through the first ear seat 6 and the second ear seat 7 so that the gate 1 and the hinge support 2 can be detachably connected, a clearance space must be reserved in the groove of the hinge support connecting groove 5 so that the pin 3 can be installed normally. The clearance space can preferably be used to place the hinge support 2. When the hydraulic movable dam needs to be transported, the hinge support 2 can be assembled and then placed in the clearance space in the hinge support connecting groove 5 on the gate 1, and then the gate 1 can be stacked up for transportation. There is no need for multiple assembly before and after transportation, which saves time and effort, reduces the space occupied, and improves the convenience of the device.

[0023] Preferably, the hydraulic lifting device includes a hydraulic telescopic rod 10, a third ear seat 8 is provided on the hinge support 2, and a fourth ear seat 9 is provided on the back water surface of the upper end of the gate 1. The upper end of the hydraulic telescopic rod 10 is hinged to the fourth ear seat 9, and the lower end is hinged to the third ear seat 8. The hydraulic telescopic rod 10 is used for lifting the gate 1. The upper end of the hydraulic telescopic rod 10 can be provided with a radial through hole and can be detachably hinged to the fourth ear seat 9 through screws and nuts, and can rotate relatively. The lower end of the hydraulic telescopic rod 10 can be provided with a radial through hole and can be detachably hinged to the third ear seat 8 through screws and nuts, and can rotate relatively. The extension of the hydraulic telescopic rod 10 will cause the water level intercepted by the gate 1 to rise, and the shortening of the hydraulic telescopic rod 10 will cause the water level intercepted by the gate 1 to drop, and the hydraulic telescopic rod 10 is detachably connected to the hinge support 2 and the gate 1, which is convenient for assembly and replacement and further improves the convenience of the device.

[0024] Preferably, a water guide eave 11 is provided at the upper end of the gate 1, and the water guide eave 11 can divert the water flow intercepted by the movable dam, reduce or prevent the movable dam from being soaked by the water flow at the connection between the hinge support 2 and the gate 1, thereby enhancing the service life of the device and reducing the replacement cost.

[0025] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
