Problems solved by technology

[0003] 1. Most freezers are sealed by closing the lid. The existing lid can only be closed unilaterally, which cannot guarantee the tightness of the joint, and needs to be opened and closed manually. The cold air evaporates quickly and wastes resources;
[0004] 2. There is no air-conditioning leakage detection equipment on the freezer. During the transportation of g...

Embodiment 1

[0039] see figure 1 A cold air leakage detection and early warning device for a refrigerated box for cold chain equipment and an implementation method thereof, comprising a refrigerated box 1 and an inner box 2 arranged inside the refrigerated box 1, a box cover 11 is arranged above the refrigerated box 1, A cold air detection device 3 is arranged between the case cover 11 and the refrigerated case body 1, and the cold air detection device 3 is electrically connected to the early warning control system 4, and the outer shell of the early warning control system 4 is fixed on the top of the case cover 11.

[0040] see Figure 2-Figure 4 , the inner box 2 is composed of two layers of covering body 21, and the temperature insulating fiber layer 22 is filled between the inner and outer covering body 21, and a temperature insulation gap is opened between the inner box body 2 and the freezing box body 1, and the inner box body Vacuum treatment in the gap between the box body 2 and t...

Embodiment approach

[0043] In order to better demonstrate the process of realizing the cold air leakage detection and early warning device for refrigerated boxes for cold chain equipment, this embodiment proposes an implementation method for the cold air leak detection and early warning device for refrigerated boxes for cold chain equipment, including the following steps:

[0044] Step 1: When the box cover 11 is pressed together with the refrigerated box body 1, multiple groups of air sensors 31 at the joint between the box cover 11 and the refrigerated box body 1 work, and the air sensors 31 are used to detect whether there is cold air leakage in the joint gap;

[0045] Step 2: When the air sensor 31 detects that there is gas in the gap, the signal is transmitted to the general control circuit 41 through the wireless signal receiving module 43, and the analysis module 44 analyzes the detected data. When the data shows that the cold air leaks, the general control circuit 41 transmits information ...

Embodiment 2

[0048] see Figure 9 A cold air leakage detection and early warning device for a refrigerated box for cold chain equipment and an implementation method thereof, comprising a refrigerated box 1 and an inner box 2 arranged inside the refrigerated box 1, a box cover 11 is arranged above the refrigerated box 1, A cold air detection device 3 is arranged between the case cover 11 and the refrigerated case 1, the cold air detection device 3 is electrically connected to the early warning control system 4, the outer casing of the early warning control system 4 is fixed on the top of the case cover 11, and the case body of the refrigerated case 1 A pressing component 5 is arranged on the outside.

[0049] see Figure 10 , the pressing assembly 5 includes an L-shaped pressing plate 51, a shaft connecting rod 52, a shaft connecting motor 53 and a downward pressure cylinder 54. One end of the L-shaped pressing plate 51 is movably socketed on the outer end surface of the freezing box 1 thr...

Abstract

The invention discloses a freezing box cold air leakage detection and early warning device for cold chain equipment and an implementation method of the device and belongs to the technical field of cold air leakage detection. The device comprises a freezing box body and an inner box body arranged in the freezing box body; a box cover is arranged above the freezing box body; and cold air detection equipment is arranged between the box cover and the freezing box body. According to the freezing box cold air leakage detection early warning device for the cold chain equipment and the implementation method of the device, cold air is effectively blocked, leakage is prevented, air propagation temperature is effectively isolated, temperature transmission is prevented, the using effect of the freezing box body is improved, adjustability of the freezing box body is guaranteed, the service life of the whole device is prolonged; so that remote reminding can be conducted, personnel can conveniently conduct inspection; objects in the freezing box body can be effectively monitored in real time, the quality of the objects is guaranteed, and continuous leakage of cold air is prevented; and automatic handling can be conducted under the condition that no person handles the objects, damage is reduced to the maximum extent, intelligence is guaranteed, and use convenience is improved.

Description

technical field [0001] The invention relates to the technical field of cold air leakage detection, in particular to a cold air leakage detection and early warning device for a freezer for cold chain equipment and an implementation method thereof. Background technique [0002] In recent years, with the adjustment of agricultural structure and the improvement of residents' consumption power, the output and circulation of fresh agricultural products have continued to rise, and people have put forward higher requirements for the safety and quality of fresh agricultural products. The country is paying more and more attention to the cold chain industry, and has continuously increased policy support for the construction of cold chain equipment and cold chain systems. Freezers have the following disadvantages: [0003] 1. Most freezers are sealed by closing the lid. The existing lid can only be closed unilaterally, which cannot guarantee the tightness of the joint, and needs to be ...
