Description

Technical Field

[0001] The utility model relates to the field of rubber dams, in particular to a rubber dam with multi-level protection functions. Background Art

[0002] A rubber dam, also known as a rubber sluice, is constructed with a high-strength synthetic fiber fabric as a load-bearing frame, coated internally and externally with rubber as a protective layer. This is then processed into a tape, anchored to a base plate to form a closed dam bag. This bag-type retaining dam is inflated with water (or air) through filling and discharge pipes. The dam top allows for overflow, and the dam height can be adjusted as needed to control upstream water levels. However, rubber dams require specialized flood discharge gates for use, as they can easily be breached by excessive flooding. Consequently, each construction of a rubber dam requires significant investment in flood discharge channels. Therefore, we propose a rubber dam with multi-level protection. Utility Model Content

[0003] The main purpose of the utility model is to provide a rubber dam with multi-level protection function, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

A filtering metal mesh cover is fixedly installed on the upper surface of the raised weir above the flood discharge protection structure. A side wall is fixedly installed on the upper surface of the raised weir. A rubber bottom plate is fixedly installed on the upper surface of the raised weir. The upper surface of the rubber bottom plate is fixed by an anchoring structure. An L-shaped three-way valve is fixedly connected to the surface of the water-injected rubber bag. One end of the flood discharge protection structure is connected to a manual turbine reducer.

[0006] Furthermore, the flood discharge protection structure includes an opening and closing valve groove, a transmission shaft, a valve core structure, a discharge channel, an input port and a sealed bearing. The valve core structure is movably installed inside the opening and closing valve groove, and a transmission shaft is fixedly inserted into the surface of the valve core structure. Sealed bearings are fixedly installed on the surface of the transmission shaft near both ends. An input port is opened on the upper part of the opening and closing valve groove, and the discharge channel is opened on the surface of the opening and closing valve groove.

[0007] Furthermore, one end of the drainage channel is communicated with the opening and closing valve groove, and the other end of the drainage channel is communicated with the downstream of the raised weir. The opening and closing valve groove is communicated with the upper space of the raised weir through the input port.

[0008] Furthermore, the filter metal mesh cover is fixed to the input port by expansion screws, and both ends of the transmission shaft are movably connected to the side wall through sealed bearings.

[0009] Furthermore, the flood discharge protection structure is connected to the output end of the manual turbine reducer through one end of the transmission shaft passing through the side wall.

[0010] Furthermore, the sealing portion of the water-injected rubber bag is fixedly mounted on the upper surface of the raised weir between the rubber bottom plate and the filtering metal mesh cover through an anchoring structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the utility model, the rubber dam can discharge flood water from the bottom of the rubber dam to the downstream through the provided flood discharge protection structure, and the size of the discharged water flow is controllable. The size of the drainage aperture can be controlled according to the size of the flood level, thereby controlling the upstream water level within a suitable range, effectively playing a flood discharge role, being simple to operate, and having low installation cost.

A filtering metal mesh cover 3 is fixedly installed on the upper surface of the raised weir 1 above the flood discharge protection structure 2. A side wall 4 is fixedly installed on the upper surface of the raised weir 1. A rubber base plate 7 is fixedly installed on the upper surface of the raised weir 1. The upper surface of the rubber base plate 7 is fixed by the anchoring structure 6. An L-shaped three-way valve 8 is fixedly connected to the surface of a water-filled rubber bladder 5. The L-shaped three-way valve 8 has a drainage port. The drainage port is connected to the interior of the water-filled rubber bladder 5 through the valve to drain water. One end of the flood discharge protection structure 2 is connected to a manual turbine reducer 9.

[0019] The flood discharge protection structure 2 includes an opening and closing valve groove 201, a transmission shaft 202, a valve core structure 203, a discharge channel 204, an input port 205 and a sealing bearing 206. The valve core structure 203 is movably installed inside the opening and closing valve groove 201, and the transmission shaft 202 is fixedly inserted on the surface of the valve core structure 203. Sealing bearings 206 are fixedly installed on the surface of the transmission shaft 202 near both ends. An input port 205 is provided on the upper part of the opening and closing valve groove 201, and the discharge channel 204 is provided on the surface of the opening and closing valve groove 201; one end of the discharge channel 204 is connected to the opening and closing valve groove 201, and the other end of the discharge channel 204 is connected to the lower end of the heightened weir 1. The opening and closing valve slot 201 is connected to the upper space of the raised weir 1 through the input port 205; the filter metal mesh cover 3 is fixed to the upper part of the input port 205 by the expansion screw 301, wherein the filter metal mesh cover 3 and both ends of the opening and closing valve slot 201 are tightly attached to the side walls 4 at both ends, and both ends of the transmission shaft 202 are movably connected to the side walls 4 through the sealing bearings 206; the flood discharge protection structure 2 is connected to the output end of the manual turbine reducer 9 through one end of the transmission shaft 202 through the side wall 4; the sealing part of the water injection rubber bag 5 is fixedly installed on the upper surface of the raised weir 1 between the rubber bottom plate 7 and the filter metal mesh cover 3 through the anchoring structure 6.
