Description

Technical Field

[0001] The invention belongs to the technical field of deicing of refrigeration equipment, and specifically refers to a deicing device for refrigeration equipment. Background Art

[0002] Refrigeration equipment mainly refers to equipment used for refrigerating crew food, refrigerating various types of cargo, and air conditioning in cabins during summer. The temperature of the evaporator and other components inside the refrigeration equipment is much lower than the dew point temperature of the ambient air when working, so that the water vapor in the air condenses into water droplets on its surface after being cooled. Over time, these water droplets gradually freeze in a low temperature environment, and the formation of ice reduces the refrigeration efficiency of the equipment.

[0003] In order to solve the icing problem of refrigeration equipment, the current heating de-icing and wooden shovel de-icing have the following technical problems: 1. It is difficult to accurately control the de-icing force by heating de-icing. When the heating power is too large, although the ice layer can be melted quickly, it may cause the local temperature to be too high, causing thermal damage to the insulation layer, refrigeration pipes and other internal components of the refrigeration equipment, affecting its performance and service life; 2. The heat from heating de-icing may not be evenly transferred to the entire ice layer, resulting in uneven melting of the ice layer. Part of the ice layer may still adhere to the surface of the equipment, affecting the refrigeration efficiency; 3. It is difficult to accurately control the scraping force when using a wooden shovel to scrape ice. If the force is too small, the ice layer cannot be effectively scraped off and the de-icing effect is poor. If the force is too large, it is very easy to scratch the surface of the evaporator, pipes and other internal components of the refrigeration equipment, destroying their original smoothness and structural integrity, thereby affecting the refrigeration performance of the equipment.

[0014] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects:

[0015] 1. Through the setting of the adjustable preheating ice scraping mechanism, it can flexibly cope with ice layers of various thicknesses. When the thickness of the ice layer is uneven, the extension distance of the shovel blade can be adjusted, and targeted adjustments can be made according to the actual conditions of the ice layer in different parts. When the shovel blade is preheated and contacts the ice layer, the part of the ice layer close to the shovel blade will melt due to the increase in temperature, thereby reducing the adhesion between the ice layer and the surface of the refrigeration equipment and the shovel blade itself. This makes it easier for the shovel blade to shovel the ice layer during the ice scraping process, reducing the force required for shoveling ice, and improving the smoothness and efficiency of ice removal. At the same time, the ice layer scraped by the shovel blade will be cracked and loosened. At this time, it is vibrated with the energy storage vibration mechanism, so that the ice layer can fall off over a large area, improving the efficiency of ice removal. Compared with simply relying on mechanical force to forcibly scrape the ice layer, the energy storage vibration method is more gentle and effective. It causes the ice layer to fall off naturally through vibration, reducing direct scratches and impact force on the surface of the refrigeration equipment, thereby reducing the risk of damage to the internal structure and components of the equipment;

[0016] 2. After the shovel blade has scraped off the ice layer and cracked it, the eccentric concentric adjustment assembly can be used to adjust the adjustment disc and the drive disc to be concentric. At this time, the shovel blade will no longer be displaced due to the rotation of the drive motor. In this way, even if the adjustable preheating ice scraping mechanism and the force storage vibration mechanism use only the same drive source, they can also achieve unilateral vibration of the ice layer;

[0017] 3. It realizes unilateral vibration of the ice layer, effectively avoiding the shovel blade from working all the time during the vibration process. Excessive force of the shovel blade may damage the internal components of the refrigeration equipment. The vibration plate vibrates with accumulated force, and the rubber strip on the vibration plate contacts the ice layer loosened by the preheated shovel blade, vibrating the ice layer so that the loosened ice layer can fall off quickly. The rubber strip has a buffering effect, avoiding excessive vibration force from causing damage to the internal components of the refrigeration equipment.

[0018] 4. Use the secondary output end of the double-stage multi-stage telescopic cylinder to control the movement of the rack, so that after the primary output end of the multi-stage telescopic cylinder drives the moving sleeve to move to the limit distance on the grip, the secondary output end of the multi-stage telescopic cylinder continues to drive it to move toward the end of the grip, and at the same time drives the incomplete gear to rotate. The incomplete gear drives the support plate to rotate 90 degrees to a vertical state, so as to de-ice the vertical surface of the refrigeration equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting disc 924 moves eccentrically and drives the scraper 913 on the T-shaped connecting frame 912 to extend out of the U-shaped support plate 8 through the contact protrusion 914. After the extended scraper 913 is preheated by the running heating rod 919, the scraper 913 scrapes the ice layer. At this time, the ice layer is broken and loosened by the scraping force.

[0041] After the adjusting disc 924 is adjusted to be concentric with the driving disc 921, the driving motor 10 is operated again, and the driving motor 10 drives the bevel gear 1 713 to rotate through the transmission belt 1 715 on the rotating shaft 11, and the bevel gear 1 713 drives the bevel gear 2 714 to rotate, and the bevel gear 2 714 drives the central shaft 723 to rotate through the transmission belt 2 716, and the central shaft 723 drives the inner rotating cylinder 724 to rotate, and the vibration cylinder 725 is squeezed by the S-shaped convex ridge 727 through the carrying convex block 729 to move, and the central shaft 723 drives the S-shaped convex ridge 727 of the inner rotating cylinder 724 to rotate. When the 720 refrigeration device is rotated away from the mounting protrusion 729, the vibration plate 726 is vibrated by the restoring force of the vibration spring 728, and the rubber strip 7210 on the vibration plate 726 contacts the ice layer loosened by the preheated shovel blade 913, and vibrates the ice layer, so that the loosened ice layer can fall off quickly. The rubber strip 7210 has a buffering effect to prevent the internal components of the refrigeration device from being damaged by excessive vibration. The rubber strip 7210 on the vibration plate 726 contacts the ice layer loosened by the preheated shovel blade 913 and vibrates repeatedly, so that the loosened ice layer can fall off quickly.

[0042] When it is necessary to de-ice the ice layer on the vertical surface of the refrigeration equipment, the multi-stage telescopic cylinder 63 is started, and the first-stage output end of the multi-stage telescopic cylinder 63 drives the movable ring 4 to move on the grip rod 1. After moving to the limit distance of the first-stage output end, the second-stage output end of the multi-stage telescopic cylinder 63 continues to push the movable ring 4 to move. At this time, the rack 62 is driven to move through the arc-shaped connecting plate 64 and the connecting rod 65, and the rack 62 drives the incomplete gear 61 to rotate. The incomplete gear 61 drives the support plate 2 to rotate 90 degrees to a vertical state, and the above-mentioned de-icing operation is repeated to de-ice the ice layer on the vertical surface of the refrigeration equipment.

[0043] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
