[0029] In order to more clearly describe the present invention, the present invention will be further described below with reference to the drawings and embodiments.

[0030] Please refer to Figures 1 to 3, the present invention discloses a magnetic material storage device, including a base 1, a protective sleeve 2 and a protective head 3. One end of the protective sleeve 2 is fixedly connected to the base 1, and the other end is provided with a thread adapted to the protective head. The protective sleeve 2 is a hollow sandwich structure, including a first sandwich layer 21 and a second sandwich layer 22. The second sandwich layer 22 is sleeved outside the first sandwich layer 21. One side of the protective sleeve 2 facing the protective head is provided with a baffle, which is fixedly connected to the protective sleeve 2, and through holes adapted to the first sandwich layer 21 and the second sandwich layer 22 are opened on the baffle. In this embodiment, the position of the protective sleeve is fixed by the base. The protective sleeve is a hollow sandwich structure, so that different objects can be effectively placed in different sandwich layers, thus achieving a protective effect. In the specific implementation process, a permanent magnet is placed in the first sandwich layer, and antifreeze is provided in the second sandwich layer, which can effectively protect the permanent magnet and prevent the permanent magnet from contacting the external environment and being corroded, affecting its magnetism. In the specific use process, the base and the protective sleeve are integrally formed, thus ensuring good sealing performance. In the use process, PVC hard plastic plates can be used, which can effectively achieve heat resistance while reducing costs. The protective head can effectively seal the protective sleeve, preventing liquids and the like from entering the interior of the protective sleeve, thus ensuring that the permanent magnet installed inside the protective sleeve will not be affected by the environment and undergo magnetic transformation. In the specific implementation process, the shape of the protective sleeve is adapted to the shape of the permanent magnet, which can be cylindrical or cubic, so as to facilitate the storage of the permanent magnet and meet the use requirements.

[0031] To implement the above solution, a magnetic material is installed in the first sandwich layer 21, and the second sandwich layer 22 is arranged as a linear pipeline and wound outside the first sandwich layer 21; the inlet 23 and the outlet 24 of the second sandwich layer 22 are communicated with the through holes. In this embodiment, the second sandwich layer is arranged in a winding manner outside the first sandwich layer. After the antifreeze is poured into the second sandwich layer, it can effectively control the temperature of the permanent magnet located in the first sandwich layer and can effectively save costs; when the whole device is buried in the road surface, after the tram with a charging coil travels on the road surface, due to the principle of electromagnetic induction, the charging coil generates electricity to meet the power required for vehicle travel; however, in the laying process, in order to achieve a better charging effect, the laying density of the magnetic material storage device is relatively large, so it is necessary to reduce the cost of a single device to a certain extent to reduce the overall cost; and because it is buried under the road surface and has a long service life, it is necessary to protect the whole device to prevent the permanent magnet from rusting or being affected by temperature changes and thus affecting its magnetism. By filling a corresponding substance, such as antifreeze, in the linear pipeline, it can effectively prevent the low temperature from affecting the magnetism of the permanent magnet and, to a certain extent, avoid the influence of high temperature on the permanent magnet.

[0032] Multiple fixing holes 11 are provided on the base 1, and the multiple fixing holes 11 are symmetrically distributed around the protective sleeve 2. In this embodiment, the fixing holes are provided to effectively fix the base, which is more convenient during installation and makes the installation faster.

[0033] The baffle is a double-layer structure, including an isolation baffle 5 and a protective baffle 4. The isolation baffle 5 and the protective baffle 4 are movably connected together; through holes are provided on the isolation baffle 5, and a protective edge 41 extending downward is provided at one end of the protective baffle 4 facing the isolation baffle 5. The protective edges 41 are symmetrically arranged on both sides of the protective baffle 4; one side of the protective baffle 4 is movably connected to the isolation baffle 5 through a hinge, and a protective plate 42 is provided on the side away from the above-mentioned side. An installation hole is provided at the lower end of the protective plate, and the upper end of the protective plate 42 is hinged to the protective baffle 4. A groove 51 is provided on the side of the isolation baffle 5 facing the protective baffle 4, and the width of the groove 51 is the same as the width of the protective edge 41. In this embodiment, the baffle is arranged in a double-layer structure, so as to form a receiving cavity for protecting the protective head. After being buried underground, it can effectively prevent soil or foreign objects from entering the receiving cavity, thereby corroding or damaging the protective head. The mutual cooperation of the groove and the protective edge further enhances the integrity of the cavity; the isolation baffle and the protective baffle are movably connected by a hinge, so that during subsequent maintenance, the maintenance is more convenient and the use safety is ensured.

[0034] Please refer to Figures 4 to 6 , the present application also discloses a usage method of a magnetic storage device, which is applied to the magnetic material storage device described above. The usage method includes the following steps:

[0035] S1: Transfer the permanent magnet to the protective sleeve of the magnetic storage structure for fixation, and mark the magnetic pole direction of the permanent magnet;

[0036] S2: According to the embedding method, dig a pre-embedded hole on the road surface that is adapted to the magnetic storage device;

[0037] S3: Place the magnetic storage device in the pre-embedded hole for fixation, and lay a hardening layer consistent with the road surface material on the outermost layer. In the specific implementation process, in step S2, the pre-embedding methods include horizontal lateral pre-embedding and vertical longitudinal pre-embedding. Horizontal lateral pre-embedding means horizontal laying on the road surface perpendicular to the vehicle traveling direction; vertical longitudinal pre-embedding means standing the permanent magnet and laying it with the magnetic pole perpendicular to the road surface direction (as Figure 4 shown), the polarities of two adjacent permanent magnets can be the same or opposite. When laying with opposite polarities, high-density laying can be adopted to improve the power generation efficiency. When laying with the same polarity, the distance between the two permanent magnets is 1-1.5 times the distance from the permanent magnet to the ground, and the optimal value is times. To prevent the two magnets from interacting with each other and affecting the power generation efficiency; when pre-buried horizontally, if the magnet occupies the entire lane, when the vehicle is driving in the middle of the road, the magnetic flux passing through the system's pickup coil becomes very small due to the direction of the magnetic field, so it is necessary to lay the magnet across two lanes (such as Figure 5 As shown in the figure), the system is in a high-efficiency power generation state. In the specific implementation process, the depth of the permanent magnet buried and the distance between the two magnets can be calculated by the formula Calculated, where is the magnetic charge of the magnet, k is the proportionality coefficient, and r is the distance between a point in the magnetic field and the magnetic pole; more specifically, through relevant calculations, a=0.5L, L, 2L, and 4L are substituted into the solution respectively, and it is known that when the magnetic flux is the largest, the angle of θ is 30 degrees, that is, the magnetic flux is the largest at Bm, and according to the law of magnetic flux, the magnetic flux from A to C increases first, then decreases, and then increases again. Therefore, there is also a point between BC where the magnetic flux is the largest, and the angle between this point and the N end is also 30 degrees. Therefore, according to the Pythagorean theorem of a triangle, the length of y is a. times, and the distance between the two magnets is
