Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0026] Embodiment 1

[0027] See Figure 2 And Figure 5 For a speed bump for generating electricity from the remaining energy of vehicle deceleration, it includes a protective cover body 1, a speed bump power generation component 2, an installation component 3 and a buffer component 4. The speed bump power generation component 2 is installed on the protective cover body 1, the installation component 3 is installed on the protective cover body 1, and the buffer component 4 is installed on one side outer wall of the protective cover body 1; a lifting groove 5 is opened on one side of the top end of the liquid pool 201, and the bottom end of the speed bump 204 is installed on the inner wall of the lifting groove 5. The pressure generated by the self-weight of the vehicle body and the reverse acceleration during vehicle deceleration are used to squeeze the speed bump 204, facilitating the speed bump 204 to descend along the lifting groove 5; a storage battery 6 is installed on the bottom inner wall of the protective cover body 1, the second conducting wires 8 are symmetrically installed on one side of the storage battery 6, and the other ends of the second conducting wires 8 are installed on the inner wall of the liquid pool 201. The first conducting wires 7 are symmetrically installed on one side of the storage battery 6, and the other ends of the first conducting wires 7 are installed on the inner wall of the liquid generator 206. The generated electricity is input into the storage battery 6 through the first conducting wires 7 and the second conducting wires 8, facilitating the storage of electricity;

[0028] The speed bump power generation assembly 2 includes a liquid pool 201, a piezoelectric plate 202, an elastic plate 203, a speed bump 204, a first liquid guide pipe 205, a liquid generator 206, a second liquid guide pipe 207, and an expansion buffer tank 208. A liquid pool 201 is fixedly connected to the outer wall of one side of the protective cover body 1. A piezoelectric plate 202 is installed on the inner wall of one side of the liquid pool 201. An elastic plate 203 is installed on the outer wall of the top end of the piezoelectric plate 202. A speed bump 204 is installed at the top end of the liquid pool 201, and the bottom end of the speed bump 204 is attached to the outer wall of the elastic plate 203. A first liquid guide pipe 205 is connected through the outer wall of one side of the protective cover body 1. A liquid generator 206 is installed on the outer wall of one end of the first liquid guide pipe 205. An expansion buffer tank 208 is installed on the inner wall of the bottom end of the protective cover body 1. A second liquid guide pipe 207 is installed between the expansion buffer tank 208 and one end of the liquid generator 206.

[0029] Working principle: A piezoelectric plate 202 is added to the speed bump 204 at the highway toll station. The pressure generated by the vehicle body weight and the reverse acceleration when the vehicle decelerates are used to squeeze the speed bump 204, so that the speed bump 204 descends along the lifting groove 5, and then the piezoelectric plate 202 is deformed by the elastic plate 203, so that the piezoelectric material in the piezoelectric plate 202 generates electricity. At the same time, when the vehicle decelerates by passing over the speed bump 204, an internal and external pressure difference is generated on the conductive liquid inside the liquid pool 201, so that indium gallium alloy flows through the first liquid guide pipe 205 into the liquid generator 206, and current is generated by electromagnetic induction. Moreover, the indium gallium alloy then flows through the second liquid guide pipe 207 into the expansion buffer tank 208. After the vehicle passes over the speed bump 204, the elastic plate 203 raises the speed bump 204 and resets the piezoelectric plate 202, then the air pressure returns to normal, the dielectric flows back, and the reverse electromotive force is collected by the one-way conductivity of the diode, thereby generating secondary power generation. Then, the generated electricity is input into the storage battery 6 through the first wire 7 and the second wire 8. By adopting a vehicle deceleration residual energy power generation isolated power supply system and coupling the energy-saving speed bump 204 of "piezoelectric-magnetohydrodynamic" power generation, not only can the trivial energy on the highway toll station be utilized, but also the cable laying can be reduced and the cost can be saved. Moreover, the energy-saving speed bump 204 of "piezoelectric-magnetohydrodynamic" power generation has the advantages of continuous external power supply, small volume, easy production, long service life, high energy conversion rate, etc.

[0030] Furthermore, according to the electricity demand of the highway toll station, energy-saving speed bumps coupling "piezoelectric-magnetohydrodynamic" power generation are matched according to at least 9 lanes of the toll station.

[0031] The weight range of a general sedan is between 800 kg and 2000 kg. Assuming the average weight of each vehicle is 1000 kg, the piezoelectric constant of the ferroelectric crystal is between 10 pC / N and 100 pC / N. Let the piezoelectric constant of the ferroelectric crystal be 60 pC / N;

[0032] According to the formula Q = F·d33 (piezoelectric constant), the magnitude of its electric charge is obtained:

[0033] 60 pC / N * 1000 kg = 600000×10-12 C

[0034] Assume that the speed of the vehicle when passing through the speed bump at the toll station is 36 kilometers per hour, and the length of the speed bump is 0.4 meters. According to the formula t = s / v, the time for the vehicle to pass through the speed bump is 0.04 seconds. Furthermore, according to the formula Q = IT, the current I generated by piezoelectricity is obtained:

[0035] 30000000×10-12 = 3×10-5 A

[0036] Referring to the data, it is found that the voltage of the crystal piezoelectric material during power generation is 1.2 - 1.4 V. According to the electric energy formula W = UI, the electric energy generated by a vehicle passing through a speed bump once is

[0037] 1.4 V × 3 A × 10-5 = 4.2×10-5 J

[0038] Converting 4.2×10-5 J to kW, we get 4.2×10-8 kW. Therefore, the electric energy generated by a vehicle passing through a speed bump is

[0039] 4.2 kW×10-8 / 0.04 s × 1 / 3600 = 0.00378 kWh

[0040] On average, 70,000 vehicles pass through the toll station every day. The electric energy that 70,000 vehicles can generate is:

[0041] 0.00378 kWh / vehicle × 70000 vehicles = 264.6 kWh

[0042] After investigation, the average daily power consumption of a single lane at a large highway toll station in Beijing is about 30 kWh. Calculated according to at least 9 lanes at the toll station, the power supply required for a large toll station in one day is:

[0043] 30 kWh × 9 = 270 kWh

[0044] Based on the above calculations, it can be seen that the power generated by the energy-saving speed bump that couples "piezoelectric - magnetohydrodynamic" power generation basically meets the power demand.

The motor 301 is inlaid and installed on the bottom inner wall of the protective cover main body 1, and the bottom end of the output shaft of the motor 301 is fixedly connected to the outer wall of the first gear 302. Starting the motor 301 causes the first gear 302 to rotate, facilitating the toothed belt 303 to drive the second gear 305 to rotate by 90 degrees; limiting discs are provided at the bottoms of the first gear 302 and the second gear 305, and the bottom end of the toothed belt 303 is in fitting connection and is installed with the top ends of the limiting discs of the first gear 302 and the second gear 305, facilitating the limiting installation of the toothed belt 303 on the first gear 302 and the second gear 305 and preventing the toothed belt 303 from falling off.

[0047] Place the protective cover main body 1 underground. At this time, start the motor 301 to cause the first gear 302 to rotate, causing the toothed belt 303 to drive the second gear 305 to rotate by 90 degrees, and then causing the elliptical wheel 306 to rotate by 90 degrees along the rotating rod 304. The protruding part of the elliptical wheel 306 squeezes the connecting plate 308, causing the limiting plate 3010 on the connecting plate 308 to move along the guiding port 307, so that the limiting plate 3010 is inserted into the interior of the designated position, thereby fixing the protective cover main body 1. When it is necessary to disassemble the protective cover main body 1, start the motor 301 to reset the first gear 302, and then, under the action of the toothed belt 303 and the second gear 305, reset the elliptical wheel 306. Then, under the action of the first spring 309, the limiting plate 3010 on the connecting plate 308 is reset along the guiding port 307, and the protective cover main body 1 is disassembled. The equipment can be quickly and limitedly installed, thereby simplifying the installation process, reducing manual auxiliary installation, and improving the installation effect.
