Description
Technical Field
[0001] This invention belongs to the field of central control system technology, and specifically relates to an energy feedback type central control system. Background Technology
[0002] Passenger and cargo transportation includes air, land, and sea transport. Air transport refers to using airplanes to transport passengers and cargo, land transport refers to using trains and trucks, and sea transport refers to using ships of different displacements to transport passengers and cargo on the ocean. The choice of these three modes depends on various transport conditions. Most ships in the current technology use diesel fuel as their primary fuel for propulsion and electrical power. Furthermore, ocean waves of varying degrees cause ships to sway from side to side, and excessively large waves can easily lead to capsizing. Therefore, capsizing is one of the most serious maritime accidents. Based on this, an energy feedback central control system is proposed. This system incorporates photovoltaic panels on the ship to generate electricity, and the swaying of these panels effectively collects potential energy from ocean waves for power generation, while also reducing the risk of capsizing during navigation. Summary of the Invention
[0003] This invention provides an energy feedback type central control system, which uses photovoltaic panels on the ship to generate electricity. The system can also effectively collect the potential energy of ocean waves by swaying the photovoltaic panels, and at the same time reduce the risk of the ship capsizing during navigation.
[0004] The technical solution adopted in this invention:
[0005] An energy feedback type central control system includes a hull, an energy feedback system, and an energy storage module. The hull has multiple supports, and a rotating shaft is rotatably mounted between two of the supports. A fixed cylinder is rotatably fitted onto the rotating shaft, and multiple magnets are mounted on the inner wall of the fixed cylinder. The fixed cylinder is fixed to the hull. The energy feedback system includes an armature and a photovoltaic panel. The armature is mounted on the rotating shaft, located inside the fixed cylinder, and matched with the magnets. Connecting rods are hinged to both sides of the bottom of the photovoltaic panel, with the ends of the connecting rods connected to the rotating shaft. Multiple springs are connected to the bottom of the photovoltaic panel and the upper surface of the hull. The energy storage module is located inside the hull and is electrically connected to the photovoltaic panel and the armature.
[0006] Furthermore, a counterweight water tank is provided on the lower surface of the photovoltaic panel, and the spring is connected between the bottom of the counterweight water tank and the upper surface of the hull. It also includes an anti-tipping adjustment system, which includes a suction pump. The suction pump is located on the hull and connected to the counterweight water tank through a hose. The suction pump extends to the bottom of the hull through a rigid pipe.
[0007] Furthermore, the anti-tipping adjustment system also includes a photovoltaic panel tilt angle detection module located on the upper surface of the photovoltaic panel and a hull tilt angle detection module located on the hull. The photovoltaic panel tilt angle detection module and the hull tilt angle detection module are electrically connected to a central control unit. The central control unit includes a sway frequency calculation module and a sway frequency coupling module. The photovoltaic panel tilt angle detection module is used to detect the tilt angle of the photovoltaic panel, and the hull tilt angle detection module is used to detect the hull tilt angle. The sway frequency calculation module calculates the sway frequency of the photovoltaic panel and the hull based on the tilt angle of the photovoltaic panel and the tilt angle of the hull. The sway frequency coupling module controls the suction pump to draw water from or deliver water to the counterweight water tank based on the sway frequency of the photovoltaic panel and the hull, so that the natural sway frequency of the photovoltaic panel is close to the sway frequency of the hull.
[0008] Furthermore, it also includes electrical equipment installed on the hull, which is electrically connected to the energy storage module.
[0009] Furthermore, the central control unit also includes a power distribution module, which is used to control the energy storage module to supply power to the electrical equipment.
[0010] Furthermore, the method for calculating the frequency by the swing frequency calculation module is as follows:
[0011] S1. The photovoltaic panel tilt angle detection module and the ship tilt angle detection module are calibrated so that one side is a positive tilt angle and the other side is a positive tilt angle;
[0012] S2. Based on the tilt angle signals transmitted by the photovoltaic panel tilt angle detection module and the hull tilt angle detection module, obtain the time period of the photovoltaic panel and the hull when adjacent maximum positive and negative oscillation tilt angles occur, respectively. The reciprocal of the time period is the oscillation frequency, where the oscillation frequency of the hull is f1 and the oscillation frequency of the photovoltaic panel is f2.
[0013] Furthermore, the swaying frequency coupling module adjusts the swaying frequency of the photovoltaic panel according to the following steps, so that the natural swaying frequency of the photovoltaic panel is close to the swaying frequency of the ship:
[0014] S1. When the swaying frequency f1 of the hull is greater than the swaying frequency f2 of the photovoltaic panel, control the suction pump to pump the water in the counterweight tank into the sea in a preset unit amount.
[0015] S2. When the swaying frequency f1 of the hull is less than the swaying frequency f2 of the photovoltaic panel, control the suction pump to deliver a preset unit amount of seawater into the counterweight tank.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] Installing photovoltaic panels on the hull can effectively collect solar energy for power generation. When the hull sways, the photovoltaic panels follow the sway of the hull with a delay, which is equivalent to the photovoltaic panels swaying on the hull. The photovoltaic panels drive the rotating shaft on the support through the connecting rod. The rotating shaft drives the armature to rotate relative to the magnet block in the fixed cylinder. The armature cuts the magnetic field lines to generate an induced electromotive force to generate electricity, which can effectively collect the potential energy of the waves. Moreover, when the hull sways, the swaying direction of the photovoltaic panels is opposite to the swaying direction of the hull. In this state, the restoring force of the spring will cause the photovoltaic panels to return to their original position. The reaction force acts on the hull to make the hull return to its original position and prevent the hull from tilting further. This helps to improve the stability of the hull and can reduce the risk of the ship capsizing during navigation. Attached Figure Description

Detailed Implementation
[0023] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.
[0024] Example 1:
[0025] See Figures 1 to 4This invention provides an energy feedback type central control system, including a hull 60, an energy feedback system 20, and an energy storage module 40. The hull 60 has four supports 26 on its deck. A rotating shaft 25 is rotatably mounted between two opposing supports 26 on the left and right sides. A fixed cylinder 24 is rotatably sleeved on the rotating shaft 25. Multiple magnets 27 are fixedly mounted on the inner wall of the fixed cylinder 24, which is fixed to the deck of the hull 60. The energy feedback system 20 includes an armature 22 and a photovoltaic panel 21. The armature 22 includes multiple wound wires and is fixedly mounted on the rotating shaft 25, located within the fixed cylinder 24. 4. A plurality of magnets 27 are located on the outer periphery of the armature 22. Connecting rods 23 are hinged at the four corners of the bottom of the photovoltaic panel 21. The lower ends of the two connecting rods 23 on the left are fixedly connected to the front and rear sides of the left rotating shaft 25, respectively, and the lower ends of the two connecting rods 23 on the right are fixedly connected to the front and rear sides of the right rotating shaft 25, respectively, so that the hull 60, the front connecting rods 23, and the photovoltaic panel 21 form a parallelogram structure. Multiple springs 16 are connected to the bottom of the photovoltaic panel 21 and the upper surface of the hull 60. Using the restoring force of the springs 16, the connecting rods 23 can support the photovoltaic panel 21 on the hull 60 (e.g., ...). Figure 2 (As shown in the figure) The energy storage module 40 uses a rechargeable battery. The energy storage module 40 is located inside the hull 60. The energy storage module 40 is electrically connected to the photovoltaic panel 21 and the armature 22. The photovoltaic panel 21 and the armature 22 can charge the energy storage module 40.
[0026] This invention utilizes the combined design of the spring 16's rebound force and the connecting rod 23 to mount the photovoltaic panel 21 on the hull 60 for effective solar energy collection and power generation. When the hull 60 swings, the photovoltaic panel 21, under inertia, follows the swing of the hull 60 with a delay (e.g., Figure 3 (As shown in the diagram), this is equivalent to the hull 60 being fixed while the photovoltaic panel 21 is rocking on the hull 60. The photovoltaic panel 21 drives the rotating shaft 25 to rotate on the support 26 via the connecting rod 23. The rotating shaft 25 drives the armature 22 to rotate relative to the magnet block 27 in the fixed cylinder 24, causing the armature 22 to cut the magnetic field lines and generate an induced electromotive force to generate electricity. This can effectively collect the potential energy of the waves for power generation. Furthermore, when the hull 60 is rocking, the direction of the photovoltaic panel 21's swing is opposite to the direction of the hull 60's swing. In this state, the restoring force of the spring 16 will cause the photovoltaic panel 21 to reset, and the reaction force acting on the hull 60 will cause the hull 60 to reset and inhibit further tilting of the hull 60. This is beneficial to improving the stability of the hull 60 and can reduce the risk of the ship capsizing during navigation.
[0027] Specifically, a counterweight water tank 34 is fixedly installed on the lower surface of the photovoltaic panel 21. The two ends of the spring 16 are respectively connected between the bottom of the counterweight water tank 34 and the upper surface of the hull 60. It also includes an anti-tipping adjustment system 10, which includes a suction pump 13. The suction pump 13 is installed on the hull 60 and connected to the counterweight water tank 34 through a hose 14. The hose 14 can deform as the counterweight water tank 34 swings. The suction pump 13 extends to the bottom of the hull 60 through a rigid pipe 15, so that the lower end of the rigid pipe 15 remains underwater.
[0028] Water can be pumped into the counterweight tank 34 using the suction pump 13 to increase the supporting mass at the upper end of the connecting rod 23, thereby reducing the natural oscillation frequency of the photovoltaic panel 21 and the counterweight tank 34. Water can also be drawn from the counterweight tank 34 and discharged into the sea using the suction pump 13, further reducing the supporting mass at the upper end of the connecting rod 23 and increasing the natural oscillation frequency of the photovoltaic panel 21 and the counterweight tank 34. This allows the natural oscillation frequency of the photovoltaic panel 21 and the counterweight tank 34 to be adjusted to be close to or consistent with the oscillation frequency of the hull 60, thereby increasing the oscillation amplitude of the counterweight tank 34 and the photovoltaic panel 21 on the hull 60 (e.g., ...). Figure 3 As shown in the figure, the swaying direction of the photovoltaic panel 21 and the counterweight water tank 34 is opposite to the swaying direction of the hull 60, which can further suppress the hull 60 from tilting and help improve the safety of sailing in large waves.
[0029] Example 2:
[0030] See Figures 1 to 4 The difference from Example 2 is as follows:
[0031] Specifically, the anti-tipping adjustment system 10 also includes a photovoltaic panel tilt angle detection module 12 fixedly mounted on the upper surface of the photovoltaic panel 21 and a hull tilt angle detection module 11 fixedly mounted on the hull 60. The photovoltaic panel tilt angle detection module 12 and the hull tilt angle detection module 11 are electrically connected to a central control unit 30. The photovoltaic panel tilt angle detection module 12 and the hull tilt angle detection module 11 use tilt angle sensors in the prior art. The central control unit 30 includes a swing frequency calculation module 31 and a swing frequency coupling module 32. The photovoltaic panel tilt angle detection... Module 12 is used to detect the tilt angle of photovoltaic panel 21, hull tilt angle detection module 11 is used to detect the tilt angle of hull 60, sway frequency calculation module 31 can calculate the sway frequency of photovoltaic panel 21 and hull 60 based on the tilt angle of photovoltaic panel 21 and hull 60, and sway frequency coupling module 32 automatically controls suction pump 13 to draw water from or deliver water to counterweight water tank 34 based on the sway frequency of photovoltaic panel 21 and hull 60, so that the natural sway frequency of photovoltaic panel 21 is close to the sway frequency of hull 60.
[0032] During navigation, the tilt angle detection module 12 and the hull tilt angle detection module 11 are used to detect the tilt angle of the photovoltaic panel 21 and the hull 60 in real time. When the hull 60 swings with the waves, the photovoltaic panel 21 will swing relative to the hull 60. The photovoltaic panel tilt angle detection module 12 and the hull tilt angle detection module 11 transmit the tilt angle signal to the swing frequency calculation module 31. After the swing frequency calculation module 31 calculates the swing frequency of the photovoltaic panel 21 and the hull 60, the swing frequency coupling module 32 controls the suction pump to draw water from or deliver water to the counterweight water tank 34 to adjust the support mass at the upper end of the connecting rod 23. In this way, the natural swing frequency of the photovoltaic panel 21 and the counterweight water tank 34 can be automatically adjusted. The natural swing frequency can be automatically adjusted according to the different degrees of waves during navigation.
[0033] Specifically, it also includes electrical equipment 50 installed on the hull 60. The electrical equipment 50 includes electricity for domestic use or electricity for controlling the hull 60. The electrical equipment 50 is electrically connected to the energy storage module 40, and the energy storage module 40 can supply power to the electrical equipment 50, thereby achieving the effect of energy saving.
[0034] Specifically, the central control unit 30 also includes a power distribution module 33, which controls the energy storage module 40 to supply power to the electrical equipment 50. The power distribution module 33 can control the power supply to the electrical equipment 50 according to the energy storage capacity of the energy storage module 40.
[0035] Specifically, the frequency calculation method of the swing frequency calculation module 31 is as follows:
[0036] S1. The photovoltaic panel tilt angle detection module 12 and the hull tilt angle detection module 11 are calibrated. A positive tilt angle is defined as a swing to the left, and a positive tilt angle is defined as a swing to the right (e.g., ...). Figure 3 (as shown);
[0037] S2. Based on the tilt angle signals transmitted by the photovoltaic panel tilt angle detection module 12 and the hull tilt angle detection module 11, the sway frequency calculation module 31 obtains the time period of the photovoltaic panel 21 and the hull 60 when adjacent maximum positive and negative sway tilt angles occur respectively. The reciprocal of the time period is the sway frequency, where the sway frequency of the hull 60 is f1 and the sway frequency of the photovoltaic panel 21 is f2.
[0038] Specifically, the swing frequency coupling module 32 adjusts the swing frequency of the photovoltaic panel 21 according to the following steps, so that the natural swing frequency of the photovoltaic panel 21 is close to the swing frequency of the hull 60:
[0039] S1. When the swaying frequency f1 of the hull 60 is greater than the swaying frequency f2 of the photovoltaic panel 21, the suction pump 13 is controlled to pump water from the counterweight tank 34 into the sea in a preset unit amount. The preset unit amount of water can be set according to the volume of the counterweight tank 34. It can be selected as 1 / 30 of the volume of the counterweight tank 34, and can also be adjusted to be larger or smaller according to the specific use. After each time seawater is pumped out in a preset unit amount, if the swaying frequency of the hull 60 is still greater than the swaying frequency of the photovoltaic panel 21, seawater is pumped out in a preset unit amount until the swaying frequency of the hull 60 is less than or equal to the swaying frequency of the photovoltaic panel 21, so that its natural swaying frequency is close to the swaying frequency of the hull 60.
[0040] S2. When the swaying frequency f1 of the hull 60 is less than the swaying frequency f2 of the photovoltaic panel 21, the suction pump 13 is controlled to deliver a preset unit amount of seawater into the counterweight tank 34. After each delivery of seawater into the counterweight tank 34 in the preset unit amount, if the swaying frequency of the photovoltaic panel 21 is still less than the swaying frequency of the hull 60, the preset unit amount of seawater is continued to be delivered into the counterweight tank 34 until the swaying frequency of the hull 60 is equal to or close to the swaying frequency of the photovoltaic panel 21, so that its natural swaying frequency is close to the swaying frequency of the hull 60.
[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
