[0035] The pressure power generation and power supply excitation device includes an L-shaped shell 22, a laminated wood structure layer 3, a force transmission keel 5, a piezoelectric material module 6, a metal mesh 7 and a battery and power supply circuit module 9. The L-shaped shell 22 is arranged along the right-angle interface formed by the curbstone 1 and the sidewalk pavement 2. The upper surface of the L-shaped shell 22 is a concave structure. The laminated wood structure layer 3 and the force transmission keel 5 are sequentially arranged in the concave structure from top to bottom, and the upper surface of the L-shaped shell is a metal elastic sheet. Two force transmission keels 5 are arranged, and the upper and lower back-to-back arrangements, that is, each keel of the upper force transmission keel is in contact with the bottom of the laminated wood structure layer 3, and each keel of the lower force transmission keel is against the upper surface of the L-shaped shell;

[0036] The piezoelectric material module 6 and the metal mesh 7 are arranged in sequence from top to bottom in the long side area of ​​the L-shaped shell 22, and the piezoelectric material module 6 and the metal mesh 7 are arranged in contact with each other. The battery and power supply circuit module 9 are arranged in the short side area of ​​the L-shaped shell 22. The metal mesh 7 is fixed on the inner wall of the L-shaped shell 22. A plurality of metal spring modules 8 are supported around the bottom of the concave structure. The metal mesh 7 is connected to the battery and power supply circuit module 9 through wires. The battery and power supply circuit module 9 is wrapped with an insulation layer 23. The battery and power supply circuit module 9 is provided with a main power supply control switch 10. The L-shaped shell 22 is riveted and fixed to the sidewalk pavement 2 through the installation limit holes 15.

[0037] The battery and power supply circuit module 9 are provided in two groups, and each group of the battery and power supply circuit module 9 corresponds to two groups of heating plate improvement devices, and each group of heating improvement devices includes a plurality of heating plates connected in series. The heating plate includes a metal shell 17, a far-infrared ceramic heating coil 18 and an infrared lamp tube 19, and the far-infrared ceramic heating coil 18 and the infrared lamp tube 19 are arranged in the metal shell 17, and a plurality of heat dissipation holes 20 are provided on the upper surface of the metal shell 17 at positions corresponding to the far-infrared ceramic heating coil 18, and the infrared lamp tube 19 is energized to irradiate the far-infrared ceramic heating coil 18 to generate heat.

When working, it can ensure that both the inner and outer sides of the far-infrared ceramic layer can receive infrared irradiation and improve the heating efficiency and shorten the heating time; the far-infrared ceramic heating coil 18 is a loop structure composed of several U-shaped structures connected in sequence, and a heat dissipation hole 20 is opened on the upper surface of the metal shell 17 corresponding to the position of each U-shaped structure.

[0038] A support and adjustment device is provided at the bottom of the short side area of ​​the L-shaped shell 22, and the support and adjustment device includes a plurality of limit blocks 12 arranged in the short side area of ​​the L-shaped shell 22 for positioning the battery and the power supply circuit module 9. Each limit block 12 is matched with a metal slide rod 11, and the metal slide rod 11 is a screw structure. The bottom of the metal slide rod 11 is in contact with the ground, and the top is connected to the corresponding limit block 12 through a thread.

[0039] There are four metal spring modules 8 in total, and two of them are fixed on the bottom of the long side area of ​​the L-shaped shell 22, and the other two are fixed on the top surface of the battery and power supply circuit module 9. This arrangement has a good supporting effect and uniform force transmission.

[0040] The outer surface of the L-shaped housing 22 and the outer surface of the metal shell 17 are both wrapped with a waterproof insulating cushion layer 13 to prevent the device from being electrically connected. A non-slip cushion layer 4 is provided on the glued wood structure layer 3 to facilitate pedestrians to step on.

[0041] This application is applied to pedestrian crossings in cold climates, which is conducive to automatically melting snow and ice in snowy conditions, reducing the manpower and time costs consumed by traffic clearance, and ensuring the safety of pedestrians in cold climates to the greatest extent. The specific installation method is:

[0042] First, the number of laying device systems needs to be determined according to the height of the curbstones and the width of the pedestrian crossing, and the corresponding waterproof insulation pads need to be laid on the curbstones and the sidewalk to level them;

[0043] Then install the prefabricated pressure power generation and power supply excitation device, perform fixed-point mechanical installation through the installation hole, and adjust the height from the ground through the limit slide rod;

[0044] Then, the wires in the pressure power generation and power supply excitation device are led out, the position is determined by staking out on the road surface, and connected to the prefabricated heating plate;

[0045] After the overall connection is completed, a small part of the road surface is excavated, the wire nodes are excavated linearly, and the heating plate nodes are excavated in a planar manner. Dig down 2-3cm, put in the road heating plate improvement device, and then backfill with asphalt;

[0046] Finally, a waterproof insulating cushion layer is laid on top of the heating plate for leveling, and then the cushion layer is painted with road warning materials.

[0047] The combination of full-process prefabrication and a small amount of on-site construction can achieve the effect of completing the installation with a small amount of manpower.

[0048] The system working time is applied to the scene where it is inconvenient to carry out timely manual road snow removal during the snowy period in severe winter. According to the use requirements, the pressure power generation and power supply excitation device is installed on the interface of the curbstone 1 and the sidewalk pavement 2. The waterproof insulation cushion layer 13 is pre-paved and riveted through the installation limit hole 15. Since the height of the curbstone 1 is 80-150mm higher than the road surface, the position is adjusted by the metal slide bar 11 and the limit block 12.

[0049] When the device is in the power storage state, pedestrians step on the glued wood structure layer 3, and the pressure passes through the force transmission keel 5 and the metal spring module 8. Each keel of the force transmission keel 5 acts on the piezoelectric material module 6, thereby generating electric energy. After the pedestrians pass by, under the action of the metal spring module 8, the upper surface of the L-shaped shell returns to its original shape, and continues to generate electric energy when the next pedestrian steps on it, thereby continuously generating electric energy. A piezoelectric material module 6 is installed on the metal mesh 7, and 6 wires are connected to the metal mesh to connect to two groups of batteries and the power supply circuit module 9 for power storage. The battery can be replaced by opening the cover. During the operation in snowy weather, pedestrians' stepping will also replenish the battery with corresponding electric energy.

[0050] In the non-working scenario, the pressure power generation and power supply excitation device mainly stores electricity, and is switched to the working scenario through the main power supply control switch 10. The two groups of batteries and the power supply circuit module 9 are respectively connected to three wires, which are respectively connected to the corresponding groups of heating improvement devices. The main power supply control switch 10 can be controlled by a wireless control device.

[0051] Each set of heating improvement devices includes a number of heating plates connected in series, such as Figure 2 As shown, several heating plates at the same position are connected in series, that is: one heating plate is connected to 3 light tubes and 3 wires. Assuming there are N painted sidewalks, a1, a2, ..., aN heating plates form a series circuit relationship, b1, b2, ..., bN heating plates form a series circuit relationship, and c1, c2, ..., cN heating plates form a series circuit relationship.

[0052] When the heating plate generates heat, it transfers heat to the road surface through the heat dissipation holes 20 (heat convection and heat radiation), firstly melting the snow on the top of the road warning paint 16, and then radiates the heat to both sides, actively melting the snow on the road surface.

[0053] This application can be used not only on sidewalks, but also in other application scenarios, such as under other road warning paints (road yellow lines, etc.). However, due to the low density and the lack of power supply source from pedestrian walking pressure, it is necessary to connect to municipal cables for power supply. The application effect is limited to actively melting the snow covering the road warning paint, helping road signs to remain eye-catching in snowy weather and improving traffic safety guidance.

[0054] The infrared ceramic heating coil 18 of the present application is made of room temperature far-infrared ceramic powder material that can be prepared at present, and has the following characteristics:

[0055] 1. It has high far-infrared emissivity and excellent light-to-heat conversion performance at room temperature. It does not rely on external heat sources and can work at room temperature.

[0056] 2. Its working principle is the infrared heating principle - the heat transfer form of infrared is radiation heat transfer, and the energy is transferred by electromagnetic waves. When the far infrared ray irradiates the heated object, part of the ray is reflected back and part is penetrated. When the wavelength of the emitted far infrared ray is consistent with the absorption wavelength of the heated object, the heated object absorbs the far infrared ray. At this time, partons and atoms "resonate" - strong vibration and rotation are generated, and the vibration and rotation increase the temperature of the object, achieving the purpose of heating.

[0057] 3. The application direction of this material is gradually expanding from the traditional drying and heating field to the fields of building materials, antibacterial materials, medical care, fuel activation, etc.

[0058] The present application is combined with a heating improvement device for a far-infrared ceramic powder heating plate, which is used to utilize the heat generated by its physical properties as a heat release source; the present application is combined with a pressure power generation and power supply excitation device installed along the sidewalk, which is used to stimulate infrared lamps through electrical energy to supplement the infrared reception required by the road surface heating material in severe cold climates with insufficient sunlight conditions, so as to maintain the heating power under severe cold conditions to enable the automated normalization of snow melting on the sidewalk surface and reduce the occurrence of traffic accidents.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
