Vegetable and fruit storage refrigeration house based on solar energy power supply

Abstract

The invention discloses a vegetable and fruit storage refrigeration house based on solar energy power supply. The structure of the vegetable and fruit storage refrigeration house is more reasonable, the solar energy at the arranging position of the refrigeration house can be sufficiently utilized, and a horizontal movement door can reliably slide. A refrigeration house body comprises a bottom terrace and mutually-connected heat preservation wall plates. A movable solar energy power supply mechanism arranged on the top of the top heat preservation wall plate is further included. The solar energy power supply mechanism is connected with a storage battery and comprises a movable base, a first lead screw base fixed to the movable base, a first lead screw located in the first lead screw base, afirst nut matched with the first lead screw, a first motor driving the first lead screw, a second lead screw base fixed to the first nut, a second lead screw located in the second lead screw base, asecond nut matched with the second lead screw, a second motor driving the second lead screw, a telescopic rod fixed to the second nut, an installing support and a universal joint connecting the telescopic rod with the installing support.

Description

technical field [0001] The invention relates to a cold store, which is specifically used for cold storage of fruits, vegetables and other items. Background technique [0002] With the increase of food types, many fruits, vegetables and other items need to be frozen and refrigerated at low temperature, so the use of cold storage is increasing; [0003] In the prior art, the cold storage body provides storage space, and the sliding door is generally used as the cold storage door, and its opening method is very popular and practical; it is also very common to use an air curtain to prevent the loss of cold air when the cold storage door is opened; we are In actual use, it is found that a large amount of dust will adhere to the filter screen of the air outlet of the air curtain machine after long-term use, resulting in poor air outlet; affecting the effect of the air curtain machine; [0004] At the same time, most of the cold storage is built outdoors for convenient pick-and-pl...

Problems solved by technology

[0003] In the prior art, the cold storage body provides storage space, and the sliding door is generally used as the cold storage door, and its opening method is very popular and practical; it is also very common to use an air curtain to prevent the loss of cold air when the cold storage door is opened; we are In actual use, it is found that a large amount of dust will adhere to the filter screen of the air outlet of the air curtain machine after long-term use, resulting in poor air outlet; affecting the effect of the air curtain machine;

[0004] At the same time, most of the cold storage is built outdoors for convenient pick-and-place, sales and other environments. The cold storage consumes a lot of power. The outdoor cold storage needs to lay sun protection nets on the roof or nearby to reduce the sun exposure, but this is contradictory. , In fact, most of the solar energy is wasted, which not only consumes a lot of energy, but also wastes energy; It doesn't make any sense, but the existing solar power generation components are bulky, highly adjustable, and difficult to adjust and move, so it is difficult to be accepted by cold storage users
