Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically a low-temperature cold storage structure. Background Technology

[0002] With social development and technological progress, cold storage facilities, as an indispensable part of the modern logistics system, play a vital role. They not only provide reliable storage and transportation solutions for the food industry but also offer stable temperature control environments for the pharmaceutical and chemical industries. Because low-temperature cold storage facilities need to maintain a low-temperature environment, their structure has some special design and construction requirements compared to ordinary warehouses. Their walls, floors, and ceilings need to be made of insulation materials, and air coolers are installed inside to cool the interior and achieve low-temperature storage of materials. The air coolers are usually installed on one side of the wall to blow air into the interior, generally lacking a guiding structure. Due to the large area of ​​the cold storage, the uniformity of cold air diffusion is poor, and local temperature control is generally not possible, resulting in a generally poor storage effect for materials. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a low-temperature cold storage structure that can evenly diffuse the cold air from the air cooler into the interior of the insulated house through the diversion pipe. At the same time, the ventilation holes of the diversion pipe can be controlled to control the local temperature inside the insulated house, which has a good storage effect on materials and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature cold storage structure, including an insulated roof and an air control unit;

[0005] Insulated roof: A cold air fan is installed at the upper end of the rear side wall. A connector pipe is installed at the rear end of the upper side wall of the insulated roof. The rear end of the connector pipe is connected to the air outlet of the cold air fan. Symmetrically distributed diversion pipes are installed in the middle of the upper side wall of the insulated roof. The rear end of each diversion pipe is connected to the interior of the connector pipe. A connecting pipe is installed at the front end of the upper side wall of the insulated roof. The front end of each diversion pipe is connected to the interior of the connecting pipe. Evenly distributed ventilation holes are opened on the lower surface of the diversion pipe.

[0006] Air control unit: Each unit is installed at the air vent on the lower surface of the split pipe;

[0007] The system also includes a controller, which is located on the front side of the insulated building. The input of the air cooler is electrically connected to the output of the controller, and the input of the controller is electrically connected to an external power source. During use, the air cooler can be evenly diffused into the interior of the insulated building through the diversion pipe. At the same time, the ventilation holes of the diversion pipe can be controlled to control the local temperature inside the insulated building, resulting in good storage effect for materials.

[0008] Furthermore, temperature sensors are evenly distributed on both the left and right side walls of the insulated roof. The output of the temperature sensors is electrically connected to the input of the controller to facilitate the detection of the internal temperature.

[0009] Furthermore, the air control unit includes a support frame and air control plates. The support frame is respectively disposed at the air vents on the lower surface of the diversion pipe. The lower end of the support frame is rotatably connected to evenly distributed air control plates to facilitate the control of the air vents of the diversion pipe.

[0010] Furthermore, the air control unit also includes a paddle, a slide, a moving bar, and a paddle post. The paddles are all located at the front end of the front pivot of the air control plate. The slides are symmetrically located at the front end of the lower surface of the support frame. Moving bars are slidably connected between two slides under the same support frame. The middle of each moving bar is provided with evenly distributed paddle posts. The paddle posts are evenly vertically connected to the paddles to facilitate the control of the air control plate.

[0011] Furthermore, the air control unit also includes electric push rods, which are respectively disposed below the support frame. The telescopic ends of the electric push rods are fixedly connected to the vertically corresponding moving bars, and the input ends of the electric push rods are electrically connected to the output ends of the controller to facilitate the control of the movement of the moving bars.

[0012] Furthermore, the rear side of the bottom wall of the insulated roof is provided with anti-collision strip one, and the left and right sides of the bottom wall of the insulated roof are provided with anti-collision strip two, which provide protection for the insulated roof.

[0013] Furthermore, the insulated roof is a double-sided color steel polyurethane insulated roof, which has good insulation effect and low construction cost.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This low-temperature cold storage structure has the following advantages:

[0015] 1. Control the controller: When the air cooler is working, it delivers cold air into the connector pipe. At the same time, the electric push rod operates. The extension end of the electric push rod retracts, causing the moving strip to slide forward along the slide block. The moving strip drives the dial to move synchronously and rotate the dial clockwise. Simultaneously, the dial and the long sliding hole of the dial slide relative to each other. The dial drives the air control plate to rotate into a vertical position. The electric push rod stops working. Then, the cold air inside the connector pipe enters the interior of the distribution pipe. The cold air then passes through the gap of the air control plate and is evenly discharged into the interior of the insulated house. During use, the air cooler's cold air can be evenly diffused into the interior of the insulated house through the diversion pipe, which can quickly and evenly cool the interior of the insulated house.

[0016] 2. Temperature sensors detect the temperature at various points inside the insulated enclosure and transmit the results to the controller. When the temperature at a certain point reaches the specified temperature, the controller controls the corresponding electric push rod to operate. The telescopic end of the electric push rod extends, and the air control vane gradually rotates to a horizontal state and then blocks the ventilation holes of the distribution pipe. Similarly, it can perform targeted air blowing, which can accurately regulate the temperature inside the insulated enclosure. It can detect the temperature at multiple points inside the insulated enclosure and control the ventilation holes of the distribution pipe, thus controlling the local temperature inside the insulated enclosure. As a result, the low-temperature cold storage has a good storage effect on materials. Attached Figure Description

The air control unit 8 also includes a lever 83, a slide 84, a moving bar 85, and a lever 86. The lever 83 drives the air control plates 82 to rotate into a vertical position.
