Technical Field

[0001] The invention relates to the technical field of electromagnetic field application, in particular to a low-frequency alternating electromagnetic field cover. Background Art

[0002] In the fields of modern cold chain logistics and food preservation, low-frequency alternating electromagnetic fields are widely used to extend the shelf life of food and inhibit the reproduction of microorganisms. The low-frequency alternating electromagnetic field in the cold storage covers the preservation of fruits, vegetables, fresh meat, and fresh seafood in the cold storage, solving the problem of extending the preservation of high-end fruits, vegetables, fresh meat, and fresh seafood in the storage, transportation, and high-temperature environments. For the preservation time of cold storage, the spatial coverage of low-frequency alternating electromagnetic fields is a key technology. However, existing electromagnetic field covering devices often have problems such as uneven electromagnetic field distribution, high power consumption, complex installation, and poor protection performance. Especially in large cold storage environments, how to efficiently and evenly cover the low-frequency alternating electromagnetic field while ensuring the safety and durability of the equipment has become a technical problem that needs to be solved urgently.

[0003] The electromagnetic field cover devices in the prior art mostly adopt non-standard designs, and a large number of customized accessories are required during installation, resulting in a long installation period and high costs. In addition, some devices have poor electromagnetic field radiation directionality and uneven coverage due to unreasonable material or structural design, which affects the use effect. At the same time, the lack of effective waterproof measures makes the equipment easily damaged in a humid environment, reducing its service life. Summary of the invention

[0004] In view of the shortcomings of the existing technology, this solution aims to provide a low-frequency alternating electromagnetic field cover, which achieves uniform coverage of the electromagnetic field, low power consumption operation and high protection performance by optimizing the structural design, selecting high-quality materials and adopting sealing technology. At the same time, this solution also provides the installation and debugging method of the cover to simplify the installation process and improve the debugging efficiency.

[0005] Specifically, the technical solution provided by the present invention is: a low-frequency alternating electromagnetic field cover, including an electrical port, a grounding port, a grounding foot, a cylindrical electrode, a plastic-sealed shell, and a grounding foot. The grounding foot is integrally provided with a grounding foot, a section of the plastic-sealed shell is mounted on the grounding foot, a cylindrical electrode is placed in the plastic-sealed shell, the electrical port of the cylindrical electrode extends out from an opening at the top of the plastic-sealed shell, and the grounding port of the cylindrical electrode is completed by a grounded stainless steel plate at the bottom of the grounding foot. The grounding connection can be completed by fixing the grounding foot to the floor in the cold storage with self-tapping screws.

[0006] The advantages of the present invention compared with the prior art are: 1) Uniform coverage: The design of the cylindrical electrode enables the electromagnetic field to uniformly cover the target area, thereby improving the preservation effect;

[0007] 2) Low power consumption: high-quality materials and reasonable structural design reduce the operating power consumption of the equipment and save energy;

[0008] 3) Easy installation: integrated design and standardized installation accessories simplify the installation process and reduce installation costs;

[0009] 4) High protection: Sealing technology and waterproof design improve the protection performance of the equipment and extend its service life;

[0010] 5) Efficient debugging: Clear debugging steps and easy-to-adjust structure make the debugging process more efficient and accurate.

[0011] Furthermore, the installation steps of the low frequency alternating electromagnetic field cover include:

[0012] 1) Use self-tapping screws to pass through the installation feet and fix the cover to the corresponding position in the cold storage according to the distribution deployment standard;

[0013] 2) The cold storage floor is connected to the negative pole of the low-frequency alternating electric field generator;

[0014] 3) Connect the electrical port in parallel with a high-voltage wire and connect it to the positive pole of the low-frequency alternating electric field generator.

[0015] Further, the debugging steps of the low-frequency alternating electromagnetic field cover include:

[0016] 1) Turn on the low-frequency alternating electric field generator and measure the electromagnetic field strength at each point of the cover;

[0017] 2) Adjust the generator parameters and fine-tune the position of the coverer so that the electromagnetic field strength at each point covered by the coverer meets the standard. Once the standard is met, it can work continuously.

[0018] Furthermore, the cylindrical electrode is made of 304 stainless steel. Based on the material properties, the cylindrical stainless steel cover formed by the cylindrical electrode can make the electromagnetic field radiate when in use, and has the advantages of uniform coverage, low power consumption and high strength.

[0019] Furthermore, the low-frequency alternating electromagnetic field cover adopts a sealing process, and the prefabricated cylindrical electrode is plastic-sealed using a plastic sealing mold, and the waterproof grade is IPX7. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figure 1 and Figure 2 As shown, the device mainly includes:

[0026] 1) Foot 3

[0027] The foot 3 is made of metal or high-strength plastic and has sufficient load-bearing capacity and stability. As the supporting structure of the entire cover, it ensures that the cover is firmly installed in the cold storage. The bottom of the foot 3 is designed with a mounting hole, which is fixed to the ground by self-tapping screws or expansion bolts.

[0028] 2) Anchor 6

[0029] The anchor seat 6 is integrally formed on the top of the anchor 3 and is made of plastic or metal, having the same corrosion resistance and stability as the anchor 3. It provides a mounting base for the plastic-encapsulated housing 5 and strengthens the connection strength between the anchor 3 and the housing. It is connected to the anchor 3 through an integrated molding process, and no additional installation steps are required.

[0030] 3) Plastic enclosure 5

[0031] The plastic housing 5 is a sealed structure, made of waterproof and corrosion-resistant plastic material, with openings on the top and bottom to accommodate the power connection port 1 and the grounding port 2 of the cylindrical electrode 4. It protects the internal cylindrical electrode 4 from the external environment and provides electrical insulation. It is installed on the footrest 6 by snap-fit, thread or other fastening methods.

[0032] 4) Cylindrical electrode 4

[0033] The cylindrical electrode 4 is a hollow tubular structure, made of 304 stainless steel, and has good conductivity and corrosion resistance. As the main component of the electromagnetic field generator, it generates a low-frequency alternating electromagnetic field by receiving a low-frequency alternating electrical signal. It is inserted through the opening of the plastic-encapsulated shell 5 and fixed inside the plastic-encapsulated shell 5, and the power port 1 and the ground port 2 extend out of the top and bottom of the shell respectively.

[0034] 5) Connect electrical port 1 to ground port 2

[0035] Both the power port 1 and the ground port 2 are standardized electrical interfaces with anti-loosening and waterproof functions. The power port 1 is used to connect the high-frequency wire to input the low-frequency alternating electric signal into the cylindrical electrode 4; the ground port 2 is fixed on the cold storage floor by self-tapping screws and connected to the negative pole of the low-frequency alternating electric field generator to form a complete circuit loop. It is connected to the high-frequency wire and the low-frequency alternating electric field generator by means of thread, buckle or crimping.

[0036] Embodiment 2

[0037] Based on the first embodiment, Figure 1 and Figure 2 As shown in the figure, the overall working principle is: when the low-frequency alternating electric field generator is working, the high-frequency wire transmits the low-frequency alternating electric signal to the cylindrical electrode 4 through the power port 1. As the main component of the electromagnetic field generator, the cylindrical electrode 4 generates a low-frequency alternating electromagnetic field after receiving the electric signal. The electromagnetic field radiates to the surrounding space with the cylindrical electrode 4 as the center, forming a uniform electromagnetic field coverage area. The grounding port 2 connects the cylindrical electrode 4 to the negative pole of the low-frequency alternating electric field generator to form a complete circuit loop to ensure the stable generation and transmission of the electromagnetic field.

[0038] Embodiment 3

[0039] On the basis of the first and second embodiments, Figure 1 and Figure 2 As shown, the installation steps of this device are:

[0040] 1) First, determine the installation location of the cover according to the layout and distribution deployment standards within the cold storage.

[0041] 2) Use tools such as self-tapping screws or expansion bolts to fix the cover to the ground at the selected location.

[0042] 3) Use a high-voltage wire to connect the power port 1 to the positive pole of the low-frequency alternating electric field generator, and connect the cold storage floor to the negative pole of the generator.

[0043] The debugging steps of this device are:

[0044] 1) Check whether the cover is installed properly and turn on the low-frequency alternating electric field generator.

[0045] 2) Use an electromagnetic field strength measuring instrument to measure the electromagnetic field strength at each point in the coverage area to ensure that the electromagnetic field is evenly distributed and the strength meets the standard.

[0046] 3) According to the measurement results, adjust the parameters of the low-frequency alternating electric field generator such as voltage, frequency, etc., and fine-tune the position of the cover to achieve the best coverage effect.

[0047] 4) When the electromagnetic field strength at each point meets the standard, the cover can work continuously to extend the shelf life of the food in the cold storage.

[0048] Embodiment 4

[0049] like Figure 1 and Figure 2As shown, this scheme adopts a radial coverage mode, which solves the problem of uniform coverage of the electromagnetic field. Not only that, it also greatly reduces power consumption and simplifies the installation process. According to this scheme, the deployment standard of the cover in the cold storage can be formulated. No matter how large the volume of the cold storage is, the cover can be deployed according to the standard distribution to obtain a satisfactory coverage effect, thereby ensuring the quality of the preservation of fruits, vegetables, fresh meat, and fresh seafood in the cold storage. The freshness period of fruits, vegetables, fresh meat, and fresh seafood in the cold storage can be extended by 1-2 months. Structurally, it includes an electrical connection port, a grounding port, an installation foot, a debugging process, a cylindrical electrode and materials, and a manufacturing and packaging process. In terms of the installation process, use self-tapping screws to pass through the installation foot to fix the cover on the floor at the corresponding position in the cold storage according to the distribution deployment standard; the cold storage floor is connected to the negative pole of the low-frequency alternating electric field generator; the electrical connection port is connected in parallel with a high-voltage wire and connected to the positive pole of the low-frequency alternating electric field generator. The installation work is completed. In terms of debugging, turn on the low-frequency alternating electric field generator, measure the electromagnetic field strength at each point of the cover, adjust the generator parameters, and fine-tune the position of the cover so that the electromagnetic field strength at each point covered by the cover meets the standard. Once the standard is met, the cover can work continuously.

[0050] The material used for the cylindrical electrode is 304 stainless steel. 304 stainless steel is a common material among stainless steels, with a density of 7.93g / cm3 and a chemical formula of 06Cr19Ni10. It contains about 19% chromium (Cr) and about 10% nickel (Ni), and the rest is mainly iron (Fe). Since the main elements of 304 stainless steel include iron (Fe), chromium (Cr), nickel (Ni), and some other trace elements such as carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), nitrogen (N), etc., the magnetic conductivity is greatly enhanced, the power consumption is small, and the electromagnetic field strength is high. The use of a cylindrical stainless steel cover can make the electromagnetic field radial, evenly covered, with low power consumption and high strength. Since this solution is used in cold storage, a sealing process is used. The prefabricated electrode is sealed with a plastic sealing mold, and its waterproof level reaches IPX7.

[0051] The electrical parameters of this device are as follows:

[0052] 1. Electromagnetic field strength: 1200-1800

[0053] 2. The electromagnetic field strength at each monitoring point is shown in Table 1:

[0054] 1 2 3 4 5 6 7 8 15.83 38.88 14.44 49.65 17.44 15.25 4.23 63.9

[0055] Table 1

[0056] It can be seen that this solution provides a low-frequency alternating electromagnetic field cover, which achieves uniform coverage of the electromagnetic field, low power consumption operation and high protection performance by optimizing the structural design, selecting high-quality materials and adopting sealing technology. At the same time, this solution also provides detailed installation and debugging methods to ensure the stable operation and long-term use effect of the cover. The cover is particularly suitable for environments such as cold storage, and can effectively extend the shelf life of food and improve the quality and safety level of food.
