Description

Technical Field

[0001] The utility model belongs to the technical field of storehouse ventilation, in particular to a ventilation device for an archive storehouse. Background Art

[0002] Archives Center is an internal organization of various agencies (including groups, schools, factories, enterprises, institutions, etc.) that uniformly preserves and manages the archives of the agency. It is an integral part of the entire agency and a professional organization of agency management and research and consulting nature. The archives room of the party, government, military and other agencies is also one of the confidential departments of the agency. From the perspective of national archives work, the archives room is the most common, largest, and most basic business organization in the national archives work organization system. Ventilation devices are generally installed in the archives room to ventilate the archives room or warehouse.

[0003] The ventilation volume of the existing ventilation devices is mostly fixed, which makes it inconvenient to adjust the ventilation volume at the vents according to needs, and it is also inconvenient to disassemble and clean the filter plates, so the practicality is low. Therefore, we propose a ventilation device for archive warehouses. Utility Model Content

[0004] The purpose of the utility model is to provide a ventilation device for an archive storeroom to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0006] The present application is specifically as follows: A ventilation device for an archive warehouse, comprising:

[0007] A box body, wherein three connecting plates are sequentially arranged on the left side of the inner cavity of the box body, ventilation plates are arranged on the right sides of the three connecting plates, connecting rods are arranged on the right sides of the three connecting plates, and a cylinder is arranged on the left side wall of the inner cavity of the box body, and the telescopic end of the cylinder is connected to the middle and lower end of the connecting rod;

[0008] A connecting pipe is located at the rear side of the box body, a ventilation fan is arranged at the middle of the rear side of the connecting pipe, and a motor is arranged at the front side of the ventilation fan.

[0009] As the preferred technical solution of this application,

[0010] The inner cavity of the box body is provided with a filter plate, and the front side of the filter plate is provided with a heating tube.

[0011] As the preferred technical solution of this application,

[0012] Slots are arranged at the left and right ends of the inner cavity of the box body, and the left and right ends of the filter plate are respectively located in the slots.

[0013] As the preferred technical solution of this application,

[0014] A switch cover is arranged on the top of the box body, and a handle is arranged on the upper end of the switch cover.

[0015] As the preferred technical solution of this application,

[0016] Mounting holes are provided at the four corners of the rear side of the connecting pipe, and support rods are provided on both left and right sides of the rear side of the connecting pipe.

[0017] As the preferred technical solution of this application,

[0018] A group of front-to-back symmetrical support frames are arranged in the middle of the rear side of the connecting pipe, the ventilation fan is located between the two opposite sides of the ventilation fans, and the driving end of the motor passes through the middle of the front support frame and is connected to the ventilation fan.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the scheme of this application:

[0021] 1. The cylinder is extended and pulls the lower end of the connecting rod to move backward and downward. The movement of the connecting rod pulls the rear ends of the three connecting plates to rotate downward. The rotation of the rear ends of the three connecting plates to the downward ends drives the front ends of the three connecting plates to rotate upward. The rotation of the front ends of the three connecting plates to the upward ends drives the three ventilation plates to open. The opening and closing angles of the ventilation plates can be adjusted, so as to adjust the ventilation volume of the device and improve the ventilation efficiency.

[0022] 2. The motor drives the ventilation fan to rotate. The rotation of the ventilation fan brings the external air into the inner cavity of the box through the connecting pipe. The air passes through the filter plate through the inner cavity of the box. The filter plate filters the impurities and dust in the air. The wind is blown out from the front side of the box and reaches the archive warehouse to ventilate the warehouse. When the air humidity in the archive warehouse is high, the heating pipe can be turned on. The external air is heated by the heating pipe and becomes warm air, which is then blown into the archive warehouse from the front side of the box to dehumidify the archive warehouse. It is very practical.

[0023] 3. The staff holds the handle on the upper end of the switch cover to open the switch door, holds the upper end of the filter plate, pulls the filter plate upward, and makes the filter plate leave the slot. The filter plate can be removed. The slot is set to facilitate the removal of the filter plate for cleaning or replacement of a new filter plate to prevent dust accumulation on the filter plate after long-term use, which affects the ventilation efficiency.
