Description

Technical Field

[0001] The utility model relates to the field of water conservancy drainage facilities, in particular to a water-injection rubber dam which is convenient for drainage. Background Art

[0002] Rubber dam, also known as rubber sluice, is made of high-strength synthetic fiber fabric as a load-bearing skeleton, coated with rubber inside and outside as a protective layer, processed into rubber tape, and then anchored on the bottom plate to form a closed dam bag. It is inflated with water (gas) through the filling and discharging pipeline to form a bag-type water retaining dam. The dam top can overflow, and the dam height can be adjusted as needed to control the upstream water level. These two types of dam bodies have fast gas filling and discharge speeds when in use, and can be used for emergency flood discharge, but their stability is poor, and the gas is easily compressed. The traditional water-injected rubber dam is filled with water very slowly when in use, and the drainage speed is also very slow when the upstream water level needs to be lowered, which reduces the speed of flood discharge during floods, and requires water sources and water injection devices for water injection, which is troublesome to operate. In order to solve the flood discharge problem, flood discharge gates are often built next to the rubber plate at this stage, which increases the cost. For this reason, we propose a water-injected rubber dam that is easy to drain. Utility Model Content

[0003] The main purpose of the utility model is to provide a water-filled rubber dam that is easy to drain, 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:

[0005] A water-injection rubber dam for easy drainage comprises a raised weir and a rubber dam body structure, wherein an upstream riverbed is fixedly connected and installed upstream of the raised weir, a downstream riverbed is connected and installed downstream of the raised weir, an anchoring structure is fixedly installed on the upper surface of the raised weir near the upstream riverbed, the rubber dam body structure is fixedly installed on the upper surface of the raised weir through the anchoring structure, a rubber bottom plate is fixedly installed on one side of the anchoring structure on the upper surface of the raised weir, a differential water filling structure is connected to the surface of the rubber dam body structure, and side walls are built and installed on the upper surface of the raised weir at both ends of the rubber dam body structure.

[0006] Furthermore, the rubber dam structure includes a water-injected rubber bag, an inflatable rubber bag, a water discharge three-way valve, a one-way inflation valve and an exhaust three-way valve. The upper surface of the water-injected rubber bag is connected to and installed with the inflatable rubber bag, the surface of the water-injected rubber bag is fixedly installed with the water discharge three-way valve near the downstream position, the upper surface of the inflatable rubber bag is connected to the one-way inflation valve, and the upper surface of the inflatable rubber bag is fixedly installed with the exhaust three-way valve on one side of the one-way inflation valve.

[0007] Furthermore, the air-inflated rubber bag and the water-injected rubber bag are separated by a rubber sheet and are not connected to each other.

[0008] Furthermore, the differential water filling structure includes a diversion high-pressure pipe, a stop valve and a filter mesh cover. The surface of the diversion high-pressure pipe is connected to the stop valve. The differential water filling structure is connected to the water injection rubber bag through one end of the diversion high-pressure pipe, and the other end of the diversion high-pressure pipe is connected to the filter mesh cover.

[0009] Furthermore, the filter screen cover is arranged in the water inside the upstream gate, and the filter screen cover is more than one meter above the riverbed.

[0010] Furthermore, the upper surface of the upstream riverbed is lower than the upper surface of the heightened weir, the upper surface of the downstream riverbed is lower than the upper surface of the upstream riverbed, and both ends of the rubber dam structure are anchored on the side wall surfaces at both ends.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the water-injected rubber dam can introduce the water inside the upstream gate into the water-injected rubber bag through the diversion high-pressure pipe in the differential water-filling structure, so that the water-injected rubber bag can be quickly filled through the water level difference by only opening the stop valve, which saves time and effort in filling water, and in conjunction with the inflatable rubber bag, the exhaust three-way valve can be opened to quickly discharge the gas when a flood comes or when the upstream water level needs to be lowered, thereby playing the role of timely flood discharge and water level lowering, and the later inflation to raise the upstream water level is faster and more convenient.

[0016] Embodiment 1:

[0017] like Figure 1As shown, a water injection type rubber dam for drainage includes a heightened weir 1 and a rubber dam body structure 6, wherein an upstream riverbed 2 is fixedly connected and installed at the upstream of the heightened weir 1, and a downstream riverbed 3 is connected and installed at the downstream of the heightened weir 1, an anchoring structure 4 is fixedly installed at a position close to the upstream riverbed 2 on the upper surface of the heightened weir 1, the rubber dam body structure 6 is fixedly installed on the upper surface of the heightened weir 1 through the anchoring structure 4, a rubber bottom plate 5 is fixedly installed on one side of the anchoring structure 4 on the upper surface of the heightened weir 1, a differential water filling structure 7 is connected to the surface of the rubber dam body structure 6, and side walls 8 are built and installed at both ends of the upper surface of the heightened weir 1 located at the rubber dam body structure 6;

[0018] The rubber dam structure 6 includes a water-filled rubber bag 601, an inflatable rubber bag 602, a water discharge three-way valve 603, a one-way inflation valve 604 and an exhaust three-way valve 605. The upper surface of the water-filled rubber bag 601 is connected to the inflatable rubber bag 602, and the surface of the water-filled rubber bag 601 is fixedly installed with the water discharge three-way valve 603 near the downstream position. The upper surface of the inflatable rubber bag 602 is connected to the one-way inflation valve 604, and the upper surface of the inflatable rubber bag 602 is located on one side of the one-way inflation valve 604 and the exhaust three-way valve 605 is fixedly installed. When multiple rubber dam structures 6 are provided, the water discharge three-way valve 603 is adjusted to a state where multiple water-filled rubber bags 601 are connected through a pipeline, and the drainage port is closed. When the exhaust three-way valve 605 is inflated, the valve is adjusted to a state where multiple inflatable rubber bags 602 are connected through a pipeline, and the exhaust port is closed. When the air is filled, only the exhaust and drainage ports need to be opened; the inflatable rubber bag 602 and the water injection rubber bag 601 are separated by a rubber sheet and are not connected to each other; the differential water filling structure 7 includes a diversion high-pressure pipe 701, a stop valve 702 and a filter screen cover 703. The surface of the diversion high-pressure pipe 701 is connected with the stop valve 702. The differential water filling structure 7 is connected to the water injection rubber bag 601 through one end of the diversion high-pressure pipe 701, and the other end of the diversion high-pressure pipe 701 is connected to the filter screen cover 703; the filter screen cover 703 is arranged in the water on the inner side of the upstream gate, and the filter screen cover 703 is more than one meter higher than the riverbed.

The filtered water is discharged into the water-injection rubber bag 601 through the diversion high-pressure pipe 701 for filling. After filling, it is closed by the stop valve 702. When filling, if there is a section of rubber dam body structure 6, the water discharge three-way valve 603 on the adjacent rubber dam body structure 6 can be connected in series through a pipeline, and the connected water discharge three-way valve 603 is opened, so that multiple rubber dam body structures 6 can share A differential water filling structure 7 is used for filling with water, so it is more convenient and simple to fill with water in the later stage.

In this way, inflation only needs to pass through a one-way inflation valve 604 to inflate all the inflatable rubber bags 602, which is more convenient and labor-saving. Similarly, exhausting only needs to open an exhaust three-way valve 605 to quickly discharge the gas for discharge.
