Description

Downhill ventilator is with preventing bird device and have this preventing bird device's downhill ventilator Technical Field The utility model relates to the field of ventilators, in particular to an anti-bird device for a downhill ventilator and the downhill ventilator with the anti-bird device. Background The downhill ventilator is a ventilation device installed on the slope of a roof, and is mainly used for promoting the circulation of indoor and outdoor air and improving the ventilation condition inside the roof. However, in practical applications, birds often enter the inside of the ventilator to nest, perch and excrete, which not only reduces the ventilation efficiency of the ventilator, but may also cause damage to the internal structure of the ventilator, and even cause safety hazards. The traditional bird prevention net mounting mode has some problems, for example, the bird prevention net cannot be completely attached to the shape of the frame structure, so that the bird prevention effect is poor, the mounting process is complex, and a large amount of manpower is consumed. In addition, some existing bird prevention devices can play a certain role in protection, but have inconvenience in installation and maintenance, and have a certain influence on the ventilation function of the ventilator. The prior patent 201920109779.9-a bird and insect prevention ventilator has the function of preventing birds and insects, but the installation mode is required to depend on an installation vertical plate, and when the bird and insect prevention ventilator is suitable for a downhill ventilator, the installation of the bird and insect prevention net plate disclosed by the patent on the downhill ventilator is troublesome. In order to improve or solve at least one of the above technical problems, it is necessary to optimize the structure of the existing ventilator or anti-bird device. Disclosure of utility model The utility model aims to provide an assembled bird preventing device which can be suitable for downhill ventilators. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The bird preventing device for the downhill ventilator comprises a ventilator framework, lateral ventilation openings are formed in the ventilator framework, the bird preventing device is mounted on the ventilator framework and comprises bird preventing mechanisms arranged on the ventilator framework, each bird preventing mechanism comprises a bird preventing net arranged on the lateral ventilation openings, each bird preventing net comprises a plurality of single nets arranged on the ventilator framework, each single net comprises a net body frame, and a steel net layer is arranged on each net body frame. Each single net end is provided with a lap joint mechanism, and each lap joint mechanism comprises a lap joint plate arranged at the single net end, and adjacent single nets or single nets are connected with adjacent ventilator frameworks through the lap joint plates. The lapping plate is fixedly connected to the ventilator framework. The net body frame comprises an annular frame, and a supporting beam is arranged in the annular frame. The steel mesh layer is embedded on the inner wall of the mesh frame or one side of the mesh frame, which is close to the ventilator framework. The bird prevention device comprises two bird prevention mechanisms which are oppositely arranged on two sides of the ventilator framework.
