Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy equipment, in particular to a transmission mechanism of a hydraulic self-controlled flap gate. Background Art

[0002] According to the transmission mechanism of the hydraulic automatic flap gate of the patent No. CN202626955U, the transmission mechanism includes a support leg and a pier, a panel is fixed on the support leg, and the support leg and the pier are movably connected through the transmission mechanism. The gate can be opened and closed through the transmission mechanism. The gate is convenient to open and close and is suitable for various water storage dams. However, there are still the following shortcomings, such as:

[0003] The above transmission mechanism is controlled by the water storage capacity, but when faced with a small amount of water storage, the gate cannot be opened to allow water to flow, and manual operation is required to open the gate, which reduces its scope of application. Therefore, we propose a transmission mechanism for a hydraulic automatic flap gate. Utility Model Content

[0004] The utility model aims to provide a transmission mechanism of a hydraulic automatic flap gate, which drives the gate to rotate by pulling the connecting block through the hydraulic cylinder, so that the rotating rod on the connecting block rotates on the inner wall of the groove, and the sliding rod on the fixed block rotates on the inner wall of the slide groove, and the rotation of the connecting block is limited to open the gate, so that water can flow out from the bottom of the gate, which solves the problem in the prior art that when faced with a small amount of water storage, the gate cannot be opened to allow water to circulate, and manual operation is required to open the gate, thereby reducing its scope of application.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a transmission mechanism of a hydraulic self-controlled flap gate, comprising a pier, a support block is fixedly connected to the top of the pier, a fixed plate is fixedly connected to the left top of the support block, a notch is opened on the inner wall of the fixed plate, a rotating rod is rotatably connected to the inner wall of the notch, a connecting block is fixedly connected to the outer surface of the rotating rod, a gate is fixedly connected to the side of the connecting block away from the rotating rod, and reinforcing ribs are fixedly connected between the gate and the connecting block.

[0007] Furthermore, a rotating rod is rotatably connected to the left side of the pier, a rotating blade is fixedly connected to the outer surface of the rotating rod, and a sliding groove is provided on the fixed plate.

[0008] Furthermore, a fixed block is fixedly connected to the outer surface of the rotating rod, a sliding rod is fixedly connected to the fixed block, and the sliding rod is slidably connected to the inner wall of the sliding groove.

[0009] Furthermore, the top of the support block is fixedly connected to a fixing frame, the fixing frame is fixedly connected to a hydraulic cylinder, the hydraulic cylinder is obliquely arranged on the fixing frame, and the side of the connecting block away from the gate is fixedly connected to a bracket 1.

[0010] Furthermore, the telescopic end of the hydraulic cylinder is rotatably connected to the inner wall of bracket one, the side of the connecting block away from the gate is fixedly connected to bracket two, and the inner wall of bracket two is rotatably connected to an arc-shaped protective plate.

[0011] Furthermore, an arc-shaped slide groove is provided on the fixing frame, the arc-shaped protective plate is slidably connected to the inner wall of the arc-shaped slide groove, and the top of the fixing frame is fixedly connected to a limit plate.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model rotates the telescopic end of the hydraulic cylinder on the inner wall of the bracket one, so that the hydraulic cylinder pulls the connecting block to rotate and drives the gate to rotate, so that the rotating rod on the connecting block rotates on the inner wall of the groove, and the sliding rod on the fixed block rotates on the inner wall of the slide groove, and the rotation of the connecting block is limited to open the gate, so that water can flow out from the bottom of the gate. The gate is opened by the hydraulic cylinder, and it can be convenient to open the gate when facing a small amount of water storage to circulate water.

[0014] 2. The utility model continuously increases the pressure of water flow on the gate by increasing the water storage volume. When the water storage volume is about to exceed the top of the gate, the pressure of the water storage volume on the gate will cause the gate on the connecting block to rotate, so that the rotating rod on the connecting block rotates on the inner wall of the notch, and the sliding rod on the fixed block rotates on the inner wall of the slide groove, thereby opening the gate, allowing the water flow to flow out from the top and bottom of the gate at the same time. As the water flows, the water pressure on the gate decreases, causing the gate to rotate as the water storage volume decreases, and then close, and can be automatically reset, realizing hydraulic self-control, improving the automation degree of the gate, and reducing labor costs and operational complexity.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A reinforcing rib 112 is fixedly connected between the gate 111 and the connecting block 110. The telescopic end of the hydraulic cylinder 201 rotates on the inner wall of the bracket 202, so that the hydraulic cylinder 201 pulls the connecting block 110 to rotate and drives the gate 111 to rotate, so that the rotating rod 106 on the connecting block 110 rotates on the inner wall of the notch 105, and the sliding rod 109 on the fixed block 108 rotates on the inner wall of the slide groove 107, thereby opening the gate 111 and allowing water to flow out from the bottom of the gate 111.

[0026] Among them Figure 4 As shown, the left side of the pier 1 is rotatably connected to a rotating rod 102, and a rotating blade 103 is fixedly connected to the outer surface of the rotating rod 102. A sliding groove 107 is provided on the fixed plate 104, and a fixed block 108 is fixedly connected to the outer surface of the rotating rod 106. A sliding rod 109 is fixedly connected to the fixed block 108. The sliding rod 109 is slidably connected to the inner wall of the sliding groove 107. When water flows through it, it will impact the rotating blade 103, so that the rotating rod 102 drives the rotating blade 103 to rotate, thereby preventing garbage and other debris from accumulating on the front side of the pier 1, and the movement of the sliding rod 109 is limited by the sliding groove 107, thereby limiting the rotation of the connecting block 110.

[0027] Among them Figure 2 As shown, the top of the support block 101 is fixedly connected to a fixing frame 2, and the fixing frame 2 is fixedly connected to a hydraulic cylinder 201, which is tiltedly arranged on the fixing frame 2. A bracket 202 is fixedly connected to the side of the connecting block 110 away from the gate 111. The gate 111 is opened by the hydraulic cylinder 201. Even when facing a small amount of water storage, the gate 111 can be easily opened to allow water to circulate.

[0028] Among them Figure 3 As shown, the telescopic end of the hydraulic cylinder 201 is rotatably connected to the inner wall of the bracket 1 202, the side of the connecting block 110 away from the gate 111 is fixedly connected to the bracket 2 203, the inner wall of the bracket 203 is rotatably connected to the arc-shaped protective plate 204, an arc-shaped slide groove 205 is opened on the fixed frame 2, the arc-shaped protective plate 204 is slidably connected to the inner wall of the arc-shaped slide groove 205, and the top of the fixed frame 2 is fixedly connected to the limiting plate 206. During the rotation process, the gate 111 will drive the arc-shaped protective plate 204 to rotate on the inner wall of the bracket 203 and slide on the inner wall of the arc-shaped slide groove 205 to protect the hydraulic cylinder 201.

[0029] A specific application of this embodiment is:

[0030] When in use, the gate is installed at a designated position, and the hydraulic cylinder 201 is started. The telescopic end of the hydraulic cylinder 201 rotates on the inner wall of the bracket 202, so that the hydraulic cylinder 201 pulls the connecting block 110 to rotate, driving the gate 111 to rotate, so that the rotating rod 106 on the connecting block 110 rotates on the inner wall of the notch 105, and the sliding rod 109 on the fixed block 108 rotates on the inner wall of the slide groove 107. The movement of the sliding rod 109 is limited by the slide groove 107, and then the rotation of the connecting block 110 is limited, so that the gate 111 is opened, so that the water flow can flow out from the bottom of the gate 111;

[0031] When the hydraulic cylinder 201 is not used, as the water storage volume increases, the pressure of the water flow on the gate 111 continues to increase. When the water storage volume is about to exceed the top of the gate 111, the pressure of the water storage volume on the gate 111 will cause the gate 111 on the connecting block 110 to rotate, so that the rotating rod 106 on the connecting block 110 rotates on the inner wall of the notch 105, and the sliding rod 109 on the fixed block 108 rotates on the inner wall of the slide 107, thereby opening the gate 111, so that the water flow can flow out from the top and bottom of the gate 111 at the same time. At this time, the arc-shaped protective plate 204 rotates on the inner wall of the bracket 203 and slides on the inner wall of the arc-shaped slide 205 to protect the hydraulic cylinder 201. As the water flows, the water pressure on the gate 111 decreases, causing the gate 111 to rotate as the water storage volume decreases, and then close. There are two ways of opening the gate hydraulically and opening the gate according to the amount of water storage, which improves the scope of application.
