Description

Electricity-free lift-off flood gate

technical field

The invention relates to an electric-free lift-off flood control gate, in particular to an electric-free lift-off flood control gate which can be used at the entrance and exit of a building to block water and prevent floods.

Background technique

Generally, in order to prevent flooding, waterproof gate equipment is usually installed at the entrance and exit of the building to prevent flooding from the gate and driveway, and the general waterproof gate equipment is usually composed of two sets corresponding to the entrance and exit The ㄈ-shaped guide rails on both sides, at least one waterproof door panel movably embedded in the ㄈ-shaped guide rail, and most of the knobs arranged on the ㄈ-shaped guide rail to lock the waterproof door panel; thus, the waterproof door panel can be used as a water-repellent use.

However, because the waterproof door panel is used to block water, it is usually made of stronger metal material, so that the waterproof door panel usually has a predetermined volume and heavy weight, so that it is not only difficult to carry by individuals, or It must be moved by a large number of people, and when it is not easy to move, it must be accurately embedded in the ㄈ-shaped guide rail with a predetermined distance, which often causes troubles in assembly during use, and because of the aforementioned reasons Generally, when a typhoon warning or heavy rain warning is released, the waterproof door panel needs to be installed first, but if no flood occurs after the first installation, it will cause obstacles when entering and exiting; moreover, when the waterproof door panel is not in use , It is necessary to find a space to store it, which leads to the lack of occupied space.

Therefore, in order to improve the deficiencies of the above-mentioned prior art, a related industry has developed a waterproof gate driven by electricity, which includes a frame arranged at the entrance and exit of a building, a waterproof door panel movable within the frame, a drive The electromechanical equipment of the waterproof door panel and a plurality of hydraulic cylinders supporting the waterproof door panel; through this, the electromechanical equipment can be used to drive the waterproof door panel to rise and fall, and the waterproof door panel is supported by the hydraulic cylinder after the waterproof door panel is raised, so as to use the waterproof door panel as a The role of water blocking.

Although the use of electric-driven waterproof gates can improve the lack of traditional waterproof gate equipment, it needs to re-transmit and distribute power to the electromechanical equipment during assembly, which makes the overall mechanism and assembly more complicated, and the cost is high. When typhoon warnings or heavy rains lead to power outages or power outages, it is impossible to use electromechanical equipment to operate the waterproof door panel. If the waterproof door panel is raised first, but there is no flood after that, it will cause obstacles when entering and exiting, resulting in poor use. There are major deficiencies; moreover, because the electric-driven waterproof gates are normally installed at the entrances and exits of buildings, they are often affected by the external environment and cause mechanical and electrical equipment to fail or be damaged, resulting in high maintenance and equipment costs. In the case of leakage of electricity due to mechanical failure caused by flooding, the safety of people entering and leaving will be endangered.

In view of this, the inventor of this case devoted himself to research and developed a power-free lifting flood gate, which can only lift the waterproof gate to form a stopper in a way that does not require electricity to achieve the waterproof function, in order to improve the above-mentioned existing Various deficiencies in technology.
