Description

Technical Field

[0001] The utility model relates to a vehicle-mounted optical purification compartment, in particular to a vehicle-mounted optical purification compartment which can continuously circulate and purify dust and other impurities in the air in the compartment to keep the compartment at a certain cleanliness level, and belongs to the technical field of vehicle supporting equipment. Background Art

[0002] With the continuous development of special vehicles used for optical applications such as large vehicle-mounted telescopes, lasers, optical cameras, and spectrometers, the requirements for air cleanliness in cabins are constantly increasing due to the high light transparency requirements of optical equipment. This is especially true when special vehicles are operating in the field, in environments with a lot of wind, sand, and dust, and a clean cabin environment is even more necessary. Currently, air purifiers are conventionally used to purify the air in the cabin. However, because the air inlet and return vents of the air purifiers are too close together, the air flow is unbalanced, resulting in the air in the corners of the cabin not being fully purified. Especially when operating in desert Gobi environments, factors such as workers opening and closing doors or opening ventilation windows on the cabin walls cause the amount of sand and dust in the environment to completely exceed the purification capacity of the air purifier, making it difficult for the air cleanliness in the cabin to meet the requirements of optical instruments. Utility Model Content

[0003] The utility model aims to provide a vehicle-mounted optical purification compartment which has a simple structure, low cost and can continuously circulate and purify impurities such as dust in the air in the compartment.

[0004] The utility model is achieved through the following technical solutions:

[0005] A vehicle-mounted optical purification compartment comprises a cabin, an optical hanger fixed on the upper side of the cabin, an FFU air purification device, a bellows and an optical platform; four rotating folding doors are symmetrically provided at both ends of one side of the cabin; an air inlet is provided in the middle of one end of the bottom plate of the optical hanger, and a return air hole is provided in the middle of the other end of the bottom plate of the optical hanger; the air outlet of the FFU air purification device is fixed downward at the air inlet hole at one end of the bottom plate of the optical hanger, and the air outlet of the FFU air purification device corresponds to the position of the air inlet hole; the bellows is placed horizontally in the optical hanger, one end of the bellows is fixedly connected to the air inlet of the FFU air purification device, and the other end of the bellows is fixedly connected to the return air hole on the bottom plate of the optical hanger; the optical platform is fixedly supported on the bottom plate of the cabin by a shock-proof base.

[0006] The purpose of the utility model can be further achieved by the following technical measures.

[0007] In the aforementioned vehicle-mounted optical purification compartment, a bracket is vertically fixed to the middle of the bottom plate of the optical hanger, and the middle part of the bellows is supported on the bracket.

[0009] In the aforementioned vehicle-mounted optical purification compartment, the optical platform is provided with a plurality of optical instrument mounting holes around it.

[0010] The utility model adopts a partition to separate the optical instrument from other equipment in the cabin, and purifies the air in the partition separately. It not only has a simple structure, low cost and easy maintenance, but also the gas flow in the cabin is balanced during purification, and the dust and other impurities in the air in the cabin can be continuously circulated and purified, including the air in the corners of the cabin can also be completely purified, so that the air in the cabin maintains a certain degree of cleanliness. Even in harsh environments such as deserts and Gobi with relatively strong winds, sand and dust, it can effectively meet the cleanliness requirements of the optical instruments in the cabin.

[0014] Figure 3 yes Figure 1 Top view of . DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model includes a cabin 1, an optical hanger 2, an FFU air purification device 3, a fixing frame 4, a bellows 5 and an optical platform 6. Four rotating folding doors 7 are symmetrically provided at both ends of one side of the cabin 1, and the four rotating folding doors 7 form a sealed area with the three bulkheads. The optical hanger 2 is fixed to the upper side of the cabin 1 by fasteners, and its bottom plate 21 divides the space inside the cabin 1 into two layers, the upper layer is the air purification device installation sealing area, and the lower layer is the optical device installation sealing area. An air inlet 22 is provided in the middle of the right end of the bottom plate 21 of the optical hanger 2. In order to maximize the air flow in the entire cabin, a return air hole 23 is provided at a position far away from the FFU air purification device 3, that is, in the middle of the left end of the bottom plate 21 of the optical hanger 2.

[0017] The FFU air purification device 3 is a fan filter unit, whose air outlet is fixed downward at the air inlet 22 at the right end of the bottom plate 21 of the optical hanger 2. The air outlet of the FFU air purification device 3 corresponds to the air inlet 22, and can input clean air into the concentrated area of ​​the lower optical equipment. The fixing frame 4 covers the FFU air purification device 3. The upper end of the fixing frame 4 is fixedly connected to the square flange 51 at the right end of the bellows 5 through fasteners, and the lower end of the fixing frame 4 is fixedly connected to the bottom plate 21 of the optical hanger 2 through fasteners. The bellows 5 is placed horizontally in the optical hanger 2, and its right end corresponds to the air inlet position of the FFU air purification device 3 and is fixedly connected to the upper end of the fixing frame 4. The square flange 52 at the left end of the bellows 5 is fixedly connected to the return air hole 23 on the bottom plate 21 of the optical hanger 2 through fasteners. A bracket 8 is vertically fixed to the middle of the bottom plate 21 of the optical hanger 2. The middle portion of the bellows 5 is supported on the bracket 8, thereby increasing the stability of the bellows 5. The optical platform 6 is fixedly supported on the bottom plate of the cabin 1 via a shock-proof base 9. It is surrounded by a number of optical instrument mounting holes 61 for mounting optical instruments.

[0018] like Figure 3 As shown, four rotating folding doors 7 are provided on one side of the cabin body 1. The rotating folding doors 7 can have three states, namely fully open, half open and fully closed. For example, personnel can use the half-open state to reduce contact with the outside air; when installing, adding and repairing equipment, the fully open state is used. The four rotating folding doors 7 can reduce the external floor area by half in the fully open state; when the optical cabin is in working state, the fully closed state is used to ensure the sealing of the cabin environment.

[0019] The FFU air purification unit 3 is opened before the optical instrument is used to ensure a clean air environment in the cabin during operation. Close the four rotating folding doors 7 and open the FFU air purification unit 3. Dust-laden air from the optical equipment area in the lower compartment is drawn into the air inlet of the FFU air purification unit 3 through the return air holes 23 on the bottom plate 21 of the optical hanger 2 and the bellows 5. It is then filtered by the FFU air purification unit 3 and finally re-entered into the optical equipment area in the lower compartment through the air inlet holes 22 on the bottom plate 21 of the optical hanger 2. This cycle repeats, forming a circulating air duct until the dust particle count reaches the national standard of less than 3,500 particles per cubic meter. The instrument can then operate normally, providing a reliable and clean working environment for the optical instruments installed on the optical platform in the compartment.

[0020] In addition to the above embodiments, the present invention may also have other implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
