Description

Intelligent refrigerator car air curtain

Technical Field

The application relates to the technical field of air curtain machines, in particular to an intelligent air curtain of a refrigerator car.

Background

The air curtain is a strong air flow generated by a through-flow or centrifugal wind wheel driven by a high-speed motor to form an invisible door curtain, can prevent the isolated inner and outer spaces from exchanging cold and hot air, and has the effects of dust prevention, pollution prevention and mosquito and fly prevention. In order to avoid the problems of cold energy leakage, energy consumption increase, internal temperature rise and the like caused when a carriage door is opened by loading and unloading the refrigerated vehicle, the air curtain machine is additionally arranged at the carriage door of the refrigerated vehicle in the recent years to become a conventional technical means. For example, patent CN201610836710.7 discloses a refrigerator car air curtain machine and a refrigerator car such that the refrigerator car air curtain machine is integrally located at the top of a cabin door of the refrigerator car. However, the efficient and reliable operation of the air curtain machine of the refrigerator car depends on the unit-time air intake quantity, the installation quality (particularly under the multi-vibration working condition) and the control mode of the air curtain machine.

Firstly, because the carriage of the refrigerated vehicle runs and jolts along with the vehicle, the working condition of the air curtain machine on the carriage is different from application places such as a market and the like, the installation reliability of the air curtain machine needs to be effectively ensured, otherwise, the carriage is easy to loose or damage due to long-term vibration connecting pieces to cause accidental crash accidents. For example, the CN201720342551.5 patent provides a jet-induced ceiling type dehumidifying and heating integrated unit, which adopts a conventional lifting mode of the whole machine and is installed once by means of fastening of a fixing piece. In order to be able to change certain installation positions, patent CN201921077865.2 discloses a refrigerated vehicle in which an air curtain provided on a rail can reciprocate linearly along the rail by means of rails symmetrically provided on the inner side wall of a refrigerating compartment. The existing scheme is used for fixing the air curtain machine by means of the thread pre-tightening force of the fastener, and certain potential loosening risks exist under the vehicle-mounted working condition. Patent CN201120492299.9 discloses a vehicle-mounted air curtain machine, in which the fixing of the air curtain machine housing is performed by a mounting plate fixed to a vehicle wall (cabin side plate), and a damper rubber is provided between the mounting plate and the air curtain machine housing. Obviously, the installation of the existing air curtain machine is generally directly and fixedly installed by adopting a fastening sleeve, and the air curtain machine is at a certain risk of loosening in a frequently-vibrated vehicle-mounted environment.

Secondly, in order to achieve better air curtain effect, the air intake in unit time needs to be ensured. Therefore, patent CN202022884659.1 discloses a refrigerator car air curtain machine, through being equipped with the shower nozzle in the lower right side of worm wheel flabellum, through high-pressure water pipe, outside high-pressure water pump that connects gradually with the shower nozzle, regularly wash the dust on the worm wheel flabellum, effectively maintain the continuous conversion rate of air curtain machine to the amount of wind. However, this method cannot effectively improve the air intake and jet flow rate of the existing motor direct-drive worm wheel fan blade, and increases the cost.

In addition, in order to provide an air curtain more energy-saving, along with the development of the technology, patent CN202111553091.8 provides an air curtain adjusting structure, a refrigerator car and an air curtain control method for the refrigerator car, which can control the air outlet direction of the inner machine by detecting a door opening and closing signal, thereby controlling the existence of the air curtain. However, the control mode is relatively single.

In the process of realizing the application, the inventor finds that the technical route is not mainly from the working environment of the refrigerated vehicle, the vibration prevention and loosening installation mode of the air curtain machine is designed, and the air curtain isolation is realized only by virtue of a single-layer air curtain without from the working condition of large temperature difference between the inside and the outside, so that the isolation capability of exchanging cold and hot air for the inside and the outside space is limited.

Therefore, compared with the existing air curtain driving motor direct-drive pump impeller scheme, the working pump impeller can effectively improve air inlet and exhaust speeds.
