Description

TECHNICAL FIELD

[0001] The present application relates to a power generation device for collecting and converting seismic energy into electric energy, which is suitable for various underground structures in seismic zones, and is a device for converting and utilizing the vibration energy of the underground space of the structure. BACKGROUND

[0002] Fossil fuels are the main energy source in the world today, but the environmental problems caused by the large-scale use of fossil fuels have not been solved, so it is urgent to find a new clean energy. Although earthquakes carry a large amount of vibration energy, there is currently no good way to collect and utilize seismic energy. There are many seismic zones distributed around the world, and how to utilize these seismic energy has become a new challenge. In addition, due to the huge energy carried by the earthquake, its destructive power is also very large. When an earthquake occurs, the power grid is usually damaged, and the power source for disaster relief and post-disaster reconstruction has become a major problem in the disaster relief process. SUMMARY

[0003] In order to be closer to the source of the earthquake to improve the energy collection efficiency, reduce the occupation of the available space of the building, and reduce the damage of the earthquake to the device, the present application provides a seismic energy conversion and utilization device for the underground space of a building and an operating method. The device is installed in the underground space of the building structure. During the period of frequent small earthquakes, the present application can collect seismic energy for daily use. When a major earthquake occurs, since the present application is installed in the underground space of the building, it is less affected by the earthquake, and the seismic energy collected by the device can be normally used for emergency power supply. In addition, in order to deal with the earthquake with greater destructive power, the device also has a certain ductility, which can ensure that the remaining devices can still operate normally when part of the device is damaged. The present application uses magnetic fluid to realize three-dimensional collection of seismic energy, which can effectively convert seismic energy with small power generation loss and high energy conversion efficiency. Since the present application can be effectively combined with the building and does not affect the normal construction of the building, it provides the possibility for practical application.

[0004] The technical scheme adopted by the present application to solve its technical problems is:

[0005] A seismic energy conversion and utilization device for underground space of a building includes a box, a magnetofluid, a spring, a balloon, an air pump, a longitudinal connecting rod, and a ring-shaped permanent magnet. The top of the box is provided with a spiral tube, the top of which is closed, and the inner cavity of the spiral tube communicates with the inner cavity of the box. The ring-shaped permanent magnet is fitted onto the spiral tube. The bottom of the box is connected to the upper end of the spring, and the lower end of the spring is fixed to the underground space of the building. The longitudinal connecting rod is welded inside the spring, and the lower end of the longitudinal connecting rod is fixed to the underground space of the building. The box is filled with the magnetofluid. The balloon is located in the inner cavity of the box, and the air inlet of the balloon communicates with the outlet of the air pump. The lower part of the box is provided with an electrode plate for drawing out induced current.

[0006] Furthermore, the lower end of the spring is welded to the steel mesh of the underground space of the building, and the spring is welded to the longitudinal connecting rod.

[0007] Furthermore, sponge pads are provided between adjacent annular permanent magnets for isolation.

[0008] Furthermore, the housing is equipped with controllable valves for controlling the entry and exit of lubricating fluid, air, and magnetofluid.

[0009] Preferably, spiral tubes are arranged at equal intervals around the top of the box.

[0010] An operating method for a seismic energy conversion and utilization device in underground building space includes the following steps:

[0011] (1) Determine the specific installation location of this device in the underground space of the building based on the building's design drawings;

[0012] (2) Adjust the dimensions of each component of this device and the spacing between the springs according to the building conditions;

[0013] (3) Install electrode plates, balloons and air pumps on the box. The electrode plates are cast together with the box and remain inside the box. Insert the balloons into the box through the reserved holes at the bottom of the box. The reserved holes are threaded holes. Tighten the air pumps to the reserved holes.

[0014] (4) Install valves on the box, embed electrode plates at the specified height of the valves, connect the wires of the electrode plates to the air pump to control the operation of the air pump; connect the electrode plate in series with the air pump to supply power to the air pump.

[0015] (5) Pour the lubricant into the tank through the valve and shake the tank to spread the lubricant evenly to reduce the friction work done by the magnetic fluid.

[0016] (6) The excess lubricant is led out, and the vacuum is continuously pumped to the tank to reach a vacuum state, further, the magnetic fluid is injected into the tank, and the tank is kept in a vacuum state; the valve is closed, and the sealing property is ensured;

[0017] (7) The annular permanent magnets are sleeved on the spiral pipe connected with the tank, and the sponge gaskets are sleeved between the annular permanent magnets to isolate;

[0018] (8) The basement formwork is erected, the bottom plate steel bars are arranged, the springs and the longitudinal connecting rods are welded to form the spring longitudinal connecting rod combined device;

[0019] (9) The spring longitudinal connecting rod combined device is welded with the steel mesh sheet. After the spring device of the whole layer is welded, the bottom plate concrete is poured;

[0020] (10) When the concrete strength reaches the design strength, the formwork is removed, and the exposed part of the tank and the spring longitudinal connecting rod combined device is welded. The electrode plates are connected in series in the unit of the whole row, the cable pipeline is arranged to form the power supply line, the maintenance door is arranged, the lead-out line is established to form the power circuit, and the power supply circuit for the power generation in the earthquake is formed.

[0021] Further, the method further comprises the following steps:

[0022] (11) When the earthquake occurs, the tank and the magnetic fluid produce relative displacement. Since the annular permanent magnets are sleeved outside the spiral pipe, when the magnetic fluid flows into the spiral pipe, the magnetic induction lines of the annular permanent magnets are cut, and the induced electromotive force is generated. The induced current is led out through the electrodes and connected with the circuit in the step (10), so that the conversion and utilization of the earthquake energy are realized;

[0023] (12) When the earthquake stops, the device can automatically adjust the liquid level of the magnetic fluid to restore the specific height to ensure the secondary use. Since the magnetic fluid has conductivity, the liquid level change of the magnetic fluid can control the opening and closing of the two groups of electrode sheets on the valve. When the liquid level is lower than the specific height, the air pump inflates the balloon to raise the liquid level to the specific height. When the liquid level is higher than the specific height, the air pump deflates the balloon to lower the liquid level to the specific height, so that the recycling effect is achieved.

[0024] Further, in the step (7), due to the adsorption of the magnets, the annular permanent magnets cannot form a spiral connection between them, which may generate a large pressure on the spiral pipe wall, affecting the service life of the device. Therefore, the sponge gaskets are sleeved between the annular permanent magnets to isolate.

[0025] The beneficial effects of the present application mainly manifest in: (1) realizing the absorption and utilization of three-dimensional vibration energy: the present application adopts magneto fluid power generation, which can realize the absorption of vibration energy from any direction and the conversion into electric energy; (2) green and non-polluted power generation process: the whole energy conversion process is energy-saving and environment-friendly, without material consumption, without material generation, realizing energy and energy conversion and utilization; (3) small electric quantity transmission loss: the installation mode of the present application has little influence on building engineering construction, can effectively connect with the building structure entity, avoids the electric quantity loss in the long-distance power generation process, and provides the possibility for large-scale production and installation; (4) high power generation efficiency: compared with the traditional vibration power generation, the present application adopts magneto fluid power generation, greatly reduces the friction, and improves the energy conversion efficiency; (5) certain self-regulating function: through the liquid level adjusting device, the liquid level height can be effectively controlled, the later-stage adjusting and maintenance cost is reduced, the magneto fluid can be recycled again, the economic effect is improved, the cost for the later-stage device upgrading and updating is saved.
