Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation technology for grain, specifically a cold storage plate for cold chain truck compartments used in grain transportation. Background Technology

[0002] Cold chain transportation of grain is a logistics process that uses temperature control technology to store, transport, and distribute grain in a low-temperature environment. Its core purpose is to maintain the freshness and nutritional value of grain and reduce loss and waste.

[0003] In the cold chain transportation of grain, it is necessary to maintain a low temperature environment. In order to reduce energy consumption, cold chain transport vehicles are required to achieve stable temperature control even without continuous power supply. Cold storage plates can meet this requirement with their advantages of high-efficiency energy storage, stable temperature and passive temperature control.

[0004] In existing technologies, cold storage plates mostly require additional fixing devices or special box structures to be installed on the smooth inner walls of refrigerated truck compartments. For example, utility model patent CN222630074U discloses a passive cold chain box with an elastic clamping mechanism for the cold storage plate. This utility model achieves the fixed installation of the cold storage plate by installing an elastic clamping mechanism on the cold storage plate and opening a slot in the inner wall of the cold chain box. Although this device can meet the requirements for the installation and fixing of the cold storage plate, it can only be used for specially designed box structures. In actual use, the versatility of the cold storage plate is low and the cost of modifying the box is high. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cold storage plate for cold chain truck compartments used in grain transportation. This cold storage plate can be fixed to the smooth inner wall of the compartment without the need for additional fixing devices, significantly improving the versatility of the cold storage plate.

[0006] To achieve the above objectives, the specific solution adopted by this utility model is as follows: a cold storage plate for a cold chain truck body used for grain transportation, comprising an outer shell for storing phase change materials, an inlet on the outer shell, a heat dissipation plate fixedly connected to the front of the outer shell, an insulation layer and multiple suction cup bases fixedly connected to the back of the outer shell, suction cup bases being rotatably connected to suction cups, and a grid plate installed in the inner cavity of the outer shell, the grid plate being in a mesh shape, and the grid plate dividing the inner cavity of the outer shell into multiple liquid storage spaces, all of which are interconnected.

[0007] As an optimized solution for the aforementioned refrigerated storage plate for grain transportation, the heat dissipation plate includes a metal outer frame and multiple heat-conducting strips fixedly arranged inside the metal outer frame. All heat-conducting strips are parallel to each other, and the distance between any two adjacent heat-conducting strips is equal.

[0008] As another optimized solution for the aforementioned refrigerated storage plate in a refrigerated truck compartment used for grain transportation, the filling port is threaded with a cap.

[0009] As another optimized solution for the aforementioned refrigerated storage plate in a refrigerated truck compartment used for grain transportation, a soft rope is connected between the cap and the filling port.

[0010] As another optimized solution for the aforementioned cold storage plate for grain transportation in a cold chain vehicle, the suction cup base is fixedly connected to the outer shell, and the suction cup base penetrates the insulation layer.

[0011] As another optimized solution for the aforementioned cold storage plate for refrigerated truck compartments used in grain transportation, the suction cup is rotatably connected to the suction cup base, and a pressure relief valve is provided on the suction cup.

[0012] As another optimized solution for the aforementioned cold storage plate for refrigerated truck compartments used in grain transportation, the suction cup base has a groove, a central shaft is fixedly installed in the groove, and a rotating plate is fixedly connected to the tail of the suction cup. A through hole is provided on the rotating plate, and the central shaft passes through the through hole.

[0013] As another optimized solution for the aforementioned refrigerated storage plate for grain transportation, the outer shell is also equipped with multiple handles on its side.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1 As shown, a cold storage plate for a cold chain vehicle used for grain transportation includes an outer shell 1 for storing phase change materials. The outer shell 1 has a filling port 5 to facilitate the filling of phase change materials and prevent spillage of phase change materials.

[0022] When installed inside the carriage, the front of the outer shell 1 faces the interior space of the carriage, and a heat dissipation plate 2 is connected to the front of the outer shell 1 to improve the heat exchange efficiency of the cold storage plate; the back of the outer shell 1 faces the inner wall of the carriage, and an insulation layer 3 is connected to the back of the outer shell 1 to prevent the cold storage plate from exchanging temperature with the outside of the carriage; multiple suction cup bases 6 are also fixedly connected to the back of the outer shell 1, and each suction cup base 6 is rotatably connected to a suction cup 7. The suction cups 7 are distributed at the four corners of the back of the outer shell 1, which can adhere to the smooth inner wall of the carriage. The installation flexibility and applicability of the cold storage plate are improved by rotating the suction cups.

[0023] The inner cavity of the outer shell 1 is equipped with a grid plate 8. The grid plate 8 is used to reduce the disturbance of the liquid, so that the cold storage plate can be more stably adsorbed on the inner wall of the carriage. The grid plate 8 divides the inner cavity of the outer shell 1 into multiple liquid storage spaces. All liquid storage spaces are interconnected, so that the phase change material can circulate in the liquid storage space.

[0024] The phase change material is obtained by compounding decanoic acid, lauric acid and palmitic acid in a ratio of 55:35:10. The phase change temperature of 12.38℃ and the latent heat of phase change of 134.99J / g of this phase change cold storage material are highly compatible with the requirements of low-temperature storage and transportation of grain. It can ensure that the cold storage plate can continuously and stably control the temperature inside the compartment during grain transportation, effectively reduce the heat accumulation generated by grain respiration and inhibit the growth of microorganisms.

[0025] Example 2

[0026] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in that the heat dissipation plate 2 includes a metal frame and multiple heat-conducting strips 9 fixedly arranged inside the metal frame. All heat-conducting strips 9 are parallel to each other, and the distance between any two adjacent heat-conducting strips 9 is equal. The multiple heat-conducting strips 9 increase the contact area between the cold storage plate and the air inside the cold chain compartment, thereby improving heat exchange efficiency.

[0027] Example 3

[0028] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that the filling port 5 is threaded with a cap 10.

[0029] The filling port 5 and the cap 10 are matched to facilitate the filling of phase change material and prevent the phase change material from spilling.

[0030] Example 4

[0031] This embodiment is an improvement on embodiment 3. Its main structure is the same as that of embodiment 3. The improvement is that a soft rope is connected between the cap 10 and the filling port 5.

[0032] When the cap 10 is removed, it can be hung on the filling port 5 by a soft rope to prevent the cap 10 from falling or being lost.

[0033] Example 5

[0034] like Figure 2 As shown, this embodiment is an improvement on embodiment 1. Its main structure is the same as embodiment 1, but the improvement lies in that the suction cup base 6 is fixedly connected to the outer shell 1, and the suction cup base 6 penetrates the insulation layer 3. In this embodiment, the insulation layer 3 uses conventional foam material and is fixed to the outer shell 1 by adhesive bonding, resulting in a simpler structure and easier installation. Considering that fixing the suction cup base 6 to the insulation layer 3 might lead to decreased stability or even detachment due to the low structural strength of the insulation layer 3, to avoid this situation, the suction cup base 6 is directly fixed to the outer shell 1 after penetrating the insulation layer 3, thereby ensuring the stability of the suction cup base 6.

[0035] Example 6

[0036] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that the suction cup 7 is rotatably connected to the suction cup base 6, and a pressure relief valve is provided on the suction cup 7.

[0037] The suction cup base 6 is connected to the suction cup 7 via a rotary joint. The suction cup 7 is equipped with a pressure relief valve to facilitate the disassembly of the cold storage plate.

[0038] Example 7

[0039] like Figure 4 As shown, this embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that: a groove is provided on the suction cup base 6, and a central shaft is fixedly installed in the groove. A rotating plate is fixedly connected to the tail of the suction cup 7, and a through hole is provided on the rotating plate. The central shaft passes through the through hole.

[0040] By setting a central shaft on the suction cup base 6, the suction cup 7 can be rotated to different angles, which makes it easier to attach the suction cup 7 to different positions on the inner wall of the carriage, thereby improving the applicability of the cold storage plate.

[0041] Example 8

[0042] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that multiple handles 4 are also installed on the side of the outer shell 1. The handles 4 facilitate the handling and installation of the cold storage plate and prevent the cold storage plate from slipping during handling or installation and causing damage to the outer shell 1.

[0043] Example 9

[0044] This embodiment is an improvement on embodiment 8. Its main structure is the same as that of embodiment 8. The improvement is that all the handles 4 are divided into two groups, and the two groups of handles 4 are symmetrically arranged on the outer shell 1.

[0045] like Figure 5 As shown, the handles 4 of adjacent cold storage plates can be fixed by rope flexible connection, thereby enhancing the overall installation stability of the cold storage plates.

[0046] Example 10

[0047] This embodiment is an improvement on embodiment 8. Its main structure is the same as that of embodiment 8. The improvement is that all the handles 4 are semi-circular and the inner side of the handle 4 forms a gripping area.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
