[0001] The utility model relates to the technical field of pharmaceutical insect prevention, and particularly relates to a device for preventing reptiles from entering the production area through the factory building door. Background Technique

[0002] In the pharmaceutical industry, the environmental cleanliness requirements of the production area are extremely high. Any minor pollution may have a serious impact on the quality of drugs. Among them, the entry of insects, especially reptiles, is a potential pollution source that cannot be ignored. As an important connection channel between the production area and the external environment, the factory building door is often one of the most vulnerable ways for reptiles and other insects to invade.

[0003] The existing insect prevention method is to install an air curtain machine above the factory building entrance and exit. The airflow generated by the air curtain machine is used to prevent mosquitoes from entering the factory building. This method has a good effect on flying insects, but has little effect on crawling insects. Crawling insects are often found in the factory building. Especially in the pharmaceutical industry, insects are strictly prohibited from entering the production clean area. Therefore, a device for preventing reptiles from entering the production area through the factory building door needs to be proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for preventing reptiles from entering the production area through the factory building door, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for preventing reptiles from entering the production area through the factory building door, including a door frame. A glass sheet is adhesively connected to the front side of the door frame. A pipe clamp is fixedly installed on the front side of the door frame. An air distribution pipe is fixedly installed inside the pipe clamp. A connecting pipe is fixedly installed at the upper end of the air distribution pipe. A fixed seat is fixedly installed on the front side of the door frame. A centrifugal fan is fixedly installed on the front side of the fixed seat. An air curtain machine is fixedly installed on the rear side of the door frame. Air holes are formed on the outer side of the air distribution pipe. <​​​​​​​​​​​​​​​Preferably, the pipe diameter of the air distribution pipe is 10mm, and the air distribution pipe is made of PVC material.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] 1. The device for preventing insects from entering the production area through the factory building door, by setting the glass sheet on the door frame, the glass surface is relatively smooth, and the friction between the feet of most insects and the glass surface is small, so it is difficult for them to climb stably on the vertical glass surface, especially for some small insects with claws that are not suitable for attaching to smooth surfaces, it is difficult for them to climb upwards more than 200mm of glass height without auxiliary support, thereby providing a primary physical barrier, and then by setting the air distribution pipe and the air hole in the inner side of the glass sheet, air can enter the air distribution pipe from the connecting pipe and be sprayed out of the air hole under the action of the centrifugal fan, since the air hole faces the glass sheet, when the airflow is blown out of the air hole, a layer of airflow with a certain speed and pressure is formed on the surface of the glass sheet, for the insects trying to climb the glass, the airflow will interfere with them, making it difficult for them to overcome the resistance of the airflow to climb upwards, thereby preventing insects from entering and causing production risks.

[0014] 2. The device for preventing insects from entering the production area through the factory building door, by setting the air curtain machine on the door frame, a high-speed airflow can be blown to form an air curtain, and in the flight process of the flying insects, the airflow blocks them, making it difficult for them to pass through the air curtain and enter the factory building, thereby effectively blocking the flying insects outside, and the combination of the two insect prevention mechanisms can work simultaneously without interference, thereby preventing different types of insects, improving the insect prevention success rate, and being simple to manufacture and low in cost.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a device for preventing crawlers from entering the production area through the factory building door, including a door frame 1, a glass sheet 2 is adhesively connected to the front side of the door frame 1, a pipe clamp 3 is fixedly installed on the front side of the door frame 1, a cloth air duct 4 is fixedly installed inside the pipe clamp 3, a connecting pipe 5 is fixedly installed at the upper end of the cloth air duct 4, a fixed seat 6 is fixedly installed on the front side of the door frame 1, a centrifugal fan 7 is fixedly installed on the front side of the fixed seat 6, and an air curtain machine 8 is fixedly installed on the rear side of the door frame 1. Through the setting of the air curtain machine 8 on the door frame 1, a high-speed air flow can be blown out to form an air curtain. During the flight of flying insects, blocked by this air flow, it is very difficult to cross the air curtain and enter the factory building, which can effectively block the flying insects outside. Wind holes 9 are provided on the outer side of the cloth air duct 4.

[0022] Please refer to Figures 2-4 , in this embodiment, four glass sheets 2 are adhesively connected to the front side of the door frame 1, and the width of the glass sheet 2 is 200 mm. Through the setting of the glass sheet 2 on the door frame 1, since the glass surface is relatively smooth, for most crawlers, the friction between their feet and the glass surface is small, and it is difficult to stably climb on the vertical glass surface. Especially for some crawlers with small body sizes and claw structures not suitable for attaching to smooth surfaces, it is very difficult to climb upward more than 200 mm in height without auxiliary support, providing a primary physical barrier. A plurality of pipe clamps 3 are fixedly installed on the front side of the door frame 1. The cloth air duct 4 is integrally in a "return" shape. The cloth air duct 4 is located inside the glass sheet 2. The connecting pipe 5 is located between the cloth air duct 4 and the centrifugal fan 7. A plurality of wind holes 9 are evenly provided on the outer side of the cloth air duct 4, and the aperture of the wind holes 9 is 1 mm. Through the setting of the cloth air duct 4 and the wind holes 9 inside the glass sheet 2, under the action of the centrifugal fan 7, air can enter the cloth air duct 4 from the connecting pipe 5 and be ejected from the wind holes 9. Since the wind holes 9 face the glass sheet 2, when the air flow blows out from these wind holes 9, an air flow layer with a certain speed and pressure will be formed on the surface of the glass sheet 2. For the crawlers trying to climb the glass, this air flow will interfere with them and make it difficult for them to overcome the resistance of the air flow and climb upward, thereby preventing production risks brought by crawlers entering. The diameter of the cloth air duct 4 is 10 mm, and the cloth air duct 4 is made of PVC material.

[0023] Working principle: through the setting of glass sheet 2 on door frame 1, because the glass surface is relatively smooth, the friction between the feet of most reptiles and the glass surface is small, and it is difficult for them to climb stably on the vertical glass surface, especially some reptiles with small body size and claw structure not suitable for attaching to smooth surface, which are difficult to climb up more than 200mm glass height without auxiliary support, providing a primary physical barrier, then through the setting of air distribution pipe 4 and air hole 9 on the inner side of glass sheet 2, the wind can enter air distribution pipe 4 from connecting pipe 5 and be sprayed from air hole 9 under the action of centrifugal fan 7, because air hole 9 is opposite to glass sheet 2, when the airflow is blown out from the air hole 9, a airflow layer with a certain speed and pressure is formed on the surface of glass sheet 2, which interferes with the reptiles trying to climb the glass, making it difficult for them to overcome the resistance of the airflow to climb upwards, thereby preventing reptiles from entering and causing production risks, through the setting of air curtain machine 8 on door frame 1, a high-speed airflow can be blown to form an air curtain, and flying insects are blocked by the airflow during flight, making it difficult for them to pass through the air curtain and enter the factory building, which can effectively block flying insects outside, the combination of the two insect prevention mechanisms can work simultaneously without interference, which can protect different types of insects and improve the insect prevention success rate, and the manufacturing is simple and the cost is low.
