Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator shaft protection, in particular to a device for shielding vents in elevator shaft rooms from rain and small animals. Background Art
[0002] The vents in the elevator shaft room are indispensable safety facilities in elevator installation. Their design and installation help the air circulation in the elevator shaft, ensuring that the shaft will not produce excessively high temperature and humidity due to the enclosure during the operation of the elevator, thereby reducing the risk of elevator failure caused by excessive temperature or humidity. At the same time, when a fire occurs, the vents can help exhaust smoke and reduce the accumulation of smoke in the elevator shaft, providing convenience for firefighters to enter and rescue, while reducing the temperature in the elevator shaft and preventing the elevator from being damaged due to overheating. However, in real life, because the vents in the elevator shaft room are through-structures, external factors will also affect the equipment in the elevator shaft room from the inside while ventilation is being carried out.
[0003] Factors that can affect the equipment in the elevator shaft room through the vents include the inflow of wind and rain, as well as small animals invading the elevator shaft room and causing damage. The former will cause electrical equipment to become damp, causing short circuits and leakage faults, and corrode the metal structure in the elevator shaft, shortening the service life of the elevator, while the latter will damage the elevator's cables, control systems and mechanical components, causing the elevator to malfunction. Therefore, the design of the vents in the elevator shaft room needs to take into account the factors of rain protection and small animal intrusion to ensure the safety of the equipment in the elevator shaft room.
[0004] In winter and summer, small animals will enter the elevator shaft through the vents to keep warm and avoid the heat, causing damage to the equipment inside. At the same time, rain, snow and strong winds will also enter the elevator shaft through the vents and cause damage. The elevator shafts in existing high-rise buildings are often not equipped with shields for ventilation efficiency. After long-term use and encountering extremely bad weather, the equipment inside is easily damaged, making it impossible for the elevator to operate normally, resulting in reduced safety and low practicality.

In order to improve the ventilation efficiency, most of them are not equipped with shielding materials. After long-term use and encountering extremely bad weather, the equipment inside is easily damaged, the elevator cannot operate normally, and the safety is reduced.
[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a device for shielding the vents of an elevator shaft room from rain and preventing small animals, comprising an elevator shaft room wall, an elevator shaft room vent is provided on the front side of the elevator shaft room wall, a wall support frame is fixedly connected to the front side of the elevator shaft room wall near the edge, a plurality of bolt holes are provided on the front side of the wall support frame, a rain shield support frame is fixedly connected to the top of the wall support frame, a plurality of rain shields are fixedly connected to the top of the rain shield support frame, a metal screen is fixedly connected to the inner wall of the elevator shaft room vent, a covering gap is provided between adjacent rain shields, and a connection with the wall is provided between the elevator shaft room wall and adjacent rain shields.
