DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Embodiment: As Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the stepping power generation device of the present utility model includes a stepping power generation mechanism 1 laid on the sidewalk and an equipment box 2 arranged on the roadside. A storage tank 3, a storage tank 4, a hydraulic motor 9 and a generator 10 are provided in the equipment box 2; the output end of the hydraulic motor 9 is connected to the shaft end of the generator 10.

[0025] The stepping power generation mechanism 1 includes a pre-buried box 5 buried on the road surface. A telescopic frame 7 that moves along the inner cavity of the pre-buried box 5 is provided in the pre-buried box 5. A stepping pedal 8 protruding from the road surface is fixed on the upper part of the telescopic frame 7. A plurality of stepping liquid storage mechanisms 6 are provided between the telescopic frame 7 and the pre-buried box 5;

[0026] The liquid outlet end of the stepping liquid storage mechanism 6 is connected to the liquid inlet pipe of the storage tank 3 through a liquid inlet pipe 11. A one-way liquid inlet valve 12 is provided on the liquid inlet pipe 11. The liquid outlet of the storage tank 3 is connected to the liquid inlet end of the hydraulic motor 9 through a first liquid outlet pipe 13. The liquid outlet end of the hydraulic motor 9 is connected to the storage tank 4 through a second liquid outlet pipe 14. The storage tank 4 is connected to the liquid inlet end of the stepping liquid storage mechanism 6 through a circulation pipe 15. A pressure gauge 18 for detecting the internal pressure of the storage tank 3 is provided on the storage tank 3. An electric control valve 16 is provided on the first liquid outlet pipe 13. A controller 17 is also provided in the equipment box 2. The pressure gauge 18 and the electric control valve 16 are both connected to the controller 17. A one-way valve 21 is provided on the circulation pipe 15. The present utility model is composed of a stepping power generation mechanism 1 buried on the road surface and a storage tank 3, a storage tank 4, a hydraulic motor 9 and a generator 10 provided in the equipment box 2. When a pedestrian steps on the stepping power generation mechanism 1, the stepping liquid storage mechanism 6 is pressed, and the stepping liquid storage mechanism 6 stores hydraulic energy for the storage tank 3. The pressure in the storage tank 3 is detected by the pressure gauge 18. When the pressure gauge 18 detects that the internal pressure of the storage tank 3 reaches the set power generation value, the electric control valve 16 is controlled to open, and the liquid with pressure drives the hydraulic motor 9 to drive the generator 10 to generate electricity. When the internal pressure of the storage tank 3 reaches the stop power generation value, the electric control valve 16 is controlled to close. In this way, energy storage and power generation are carried out, ensuring the stability of power generation and preventing the occurrence of sudden changes in the power generation voltage due to the number of people.

[0027] Among them, the stepping pressure storage mechanism 6 includes a positioning cylinder 601, and a piston block 602 that moves along the inner cavity of the positioning cylinder 601 is arranged inside the positioning cylinder 601. A return spring 603 is arranged between the piston block 602 and the inner cavity of the positioning cylinder 601. A telescopic rod 604 extending outside the positioning cylinder 601 is arranged on the back side of the piston block 602. The end of the telescopic rod 604 is fixed to the telescopic frame 7. The positioning cylinder 601 is fixed to the embedded box 5. An inlet pipe 605 and an outlet pipe 606 that are communicated with the inner cavity of the positioning cylinder 601 are arranged at the bottom of the positioning cylinder 601. The inlet pipe 605 is connected to the inlet pipeline 11, and the outlet pipe 606 is connected to the first outlet pipeline 13. By setting the specific stepping pressure storage mechanism 6 to perform stepping pressure storage, during stepping, the telescopic rod 604 drives the piston block 602 to move downward, then the liquid in the inner cavity of the positioning cylinder 601 is pressed. A one-way inlet valve 12 is arranged at the liquid inlet end of the positioning cylinder 601, which avoids the backflow of the inlet liquid. Then the liquid can only flow through the energy storage tank 3. When not stepping, under the action of the return spring 603, the piston block 602 moves upward, and the liquid in the storage tank 4 enters the inner cavity of the positioning cylinder 601. The storage tank 4 is connected to the liquid inlet end of the stepping pressure storage mechanism 6 through a circulation pipeline 15. A one-way valve 21 is arranged on the circulation pipeline 15, so that only one-way liquid inlet can be carried out to avoid the backflow of the liquid, thus forming a closed circulation loop.

[0028] Among them, the up and down lifting height of the telescopic rod 604 is 1-2 cm. In this way, the up and down amplitude is small, and discomfort will not be generated during the walking and stepping process.

[0029] Among them, a plurality of anti-slip protrusions are arranged on the surface of the stepping pedal 8, thus playing an anti-slip role.

[0030] Among them, the controller 17 controls the opening and closing of the electromagnetic valve 16 according to the internal pressure of the energy storage tank 3 detected by the pressure gauge 18. When the pressure gauge 18 detects that the internal pressure of the energy storage tank 3 reaches the set power generation value, it controls the electromagnetic valve 16 to open. Then the liquid with pressure drives the hydraulic motor 9, and drives the generator 10 to generate electricity. When the internal pressure of the energy storage tank 3 reaches the stop power generation value, it controls the electromagnetic valve 16 to close. In this way, the power generation is automatically and intelligently controlled without manual control.

[0031] Among them, the diameter of the positioning cylinder 601 is 5-8 cm. In this way, the internal volume of the positioning cylinder is relatively large, and more liquid can be pressed in when stepping.

[0032] Among them, a ventilation pipe 19 is arranged on the storage tank 4, and an air filter 20 is installed at the outer end of the ventilation pipe 19, so that a pressure difference is formed between the storage tank and the energy storage tank.

[0033] During operation, this type of stepping power generation device consists of a stepping generator 10 structure buried in the road surface and a storage tank 3, a storage tank 4, a hydraulic motor 9, and a generator 10 provided in the equipment box 2. When a pedestrian steps on the stepping generator 10 structure, the stepping liquid storage mechanism 6 is pressed, and the stepping liquid storage mechanism 6 hydraulically stores energy in the energy storage tank 3, and the pressure gauge 18 detects the pressure in the energy storage tank 3. When the pressure gauge 18 detects that the internal pressure of the energy storage tank 3 reaches the set power generation value, the control solenoid valve 16 is opened, and the liquid with pressure drives the hydraulic motor 9, and the generator 10 generates electricity. When the internal pressure of the energy storage tank 3 reaches the stop power generation value, the control solenoid valve 16 is closed. In this way, energy storage and power generation are carried out, ensuring the stability of power generation and preventing the occurrence of sudden fluctuations in the power generation voltage due to the number of people.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
