Description

Technical Field

[0002] Hydraulic accumulator systems can store pressure, flow, and mechanical energy, providing flow and pressure stability and enabling adjustment of pressure and flow. In a hydraulic accumulator system, liquid is compressed by an elastomer and gas and stored in a sealed container. The pressure within the container changes with the volume of the liquid. When the hydraulic accumulator system needs to store energy, it does so by reducing the volume of the liquid within the container. When the hydraulic accumulator system needs to release energy, it does so by increasing the volume of the liquid within the container.

[0003] The working principle of a piston-type hydraulic accumulator system is to convert the pressure energy in the hydraulic system into gravitational potential energy by lifting a mass loaded on a sealed piston.

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0047] For easier understanding, see Figure 1 and Figure 2The present invention provides an embodiment of a hydraulic energy storage and discharge adaptive control system, comprising: a cylinder 1, a piston plate 2, a counterweight shaft 3, a counterweight assembly 4, a drive mechanism 5, a laser rangefinder 7, an energy storage valve module 8, an energy discharge valve module 9, and a controller 6. A water inlet is defined at the bottom of one side wall of the cylinder 1, and a water outlet is defined at the bottom of the other side wall of the cylinder 1. An energy storage valve module 8 is mounted outside the water inlet and is electrically connected to the controller 6. An energy discharge valve module 9 is mounted outside the water outlet and is electrically connected to the controller 6. The piston plate 2 is slidably installed inside the cylinder 1, and the driving mechanism 5 is installed on the top of the piston plate 2. The bottom of the counterweight shaft 3 is rotatably connected to the top of the piston plate 2 through the driving mechanism 5. The shaft body of the counterweight shaft 3 is fixed with a number of pressure bearing blocks 3-1 in a stepped manner. The several pressure bearing blocks 3-1 are rotated in sequence on the counterweight shaft 3 at preset angles according to the step height and are arranged in a circumferential array. The driving mechanism 5 is connected to the controller 6, and the driving mechanism 5 is used to drive the counterweight shaft 3 to rotate horizontally under the control of the controller 6. The counterweight assembly 4 includes a receiving plate 4-2 and a counterweight block 4-1. The receiving plate 4-2 is fixed inside the cylinder 1 parallel to the piston plate 2 and is arranged higher than the piston plate 2. The receiving plate 4-2 is provided with through holes for the counterweight shaft 3 and the pressure bearing block 3-1 to pass through. The counterweight block 4-1 is placed on top of the receiving plate 4-2. The counterweight block 4-1 is provided with a through hole of the same shape as the pressure bearing block 3-1. The through hole on the receiving plate 4-2 is larger than the through hole on the counterweight block 4-1. There are at least two counterweight assemblies 4, and adjacent two counterweight assemblies 4 are spaced apart in the height direction. A laser rangefinder 7 is fixedly mounted on the counterweight assembly 4 and is electrically connected to the controller 6. The laser rangefinder 7 is used to measure the height position of the piston plate 2.

[0048] It should be noted that the cylinder 1 can be constructed of two halves fastened together with bolts 10 and a sealing ring. A piston plate 2 is disposed within the cylinder 1. When the valve of the energy storage valve module 8 is opened and the valve of the energy release valve module 9 is closed, water can enter the cylinder 1 from the outside through the water inlet of the cylinder 1, causing the piston plate 2 to rise. A laser rangefinder 7 measures the height change of the piston plate 2 and transmits this height information to the controller 6. Based on the height position of the piston plate 2, the controller 6 calculates the energy storage capacity of the cylinder 1 and determines the load-bearing capacity of the counterweight shaft 3. As piston plate 2 rises, counterweight shaft 3 rises with it. The receiving block 3-1 at the top of counterweight shaft 3 passes through the through-hole in receiving plate 4-2. Controller 6 determines the load-bearing capacity of counterweight shaft 3 based on the energy storage capacity of cylinder barrel 1 and the acquired wave energy data. When counterweight block 4-1 needs to be added to counterweight shaft 3, drive mechanism 5 controls the rotation of counterweight shaft 3, causing the corresponding pressure receiving block 3-1 to lift counterweight block 4-1, forming a hydraulic energy storage counterweight and achieving the function of increasing the hydraulic energy storage limit. When the valve of energy storage valve module 8 is closed and the valve of energy discharge valve module 9 is opened, the water in cylinder barrel 1 flows out of the water outlet of cylinder barrel 1, and piston plate 2 descends. Laser rangefinder 7 measures the height change of piston plate 2 and transmits this height information to controller 6. When the piston plate 2 descends, the counterweight shaft 3 descends along with the piston plate 2. When the pressure bearing block 3-1 on the counterweight shaft 3, which bears the counterweight 4-1, descends to the through hole of the bearing plate 4-2, the counterweight 4-1 is supported by the bearing plate 4-2, and the pressure bearing block 3-1 is separated from the counterweight 4-1, thereby reducing the hydraulic energy storage limit.

[0049] It should also be noted that there are at least two counterweight assemblies 4. In the embodiment of the present invention, there is no restriction on the number of counterweight assemblies 4. In a specific practical application scenario, the number of counterweight assemblies 4 can be configured according to actual needs. The laser rangefinder 7 is installed on the counterweight assembly 4 closest to the piston plate 2 to facilitate the measurement of the height of the piston plate 2. The shaft body of the counterweight shaft 3 is fixed with a number of pressure bearing blocks 3-1 in a stepped manner, and the number of pressure bearing blocks 3-1 on the counterweight shaft 3 is not less than the number of counterweight assemblies 4. A number of pressure bearing blocks 3-1 are arranged in a circumferential array on the counterweight shaft 3 in sequence of stepped heights to preset angles, which is conducive to quickly, evenly and accurately controlling the rotation adjustment of the counterweight shaft 3 driven by the driving mechanism 5. In a specific embodiment, as Figure 4 and Figure 5 As shown, the pressure bearing blocks 3 - 1 are triangular in structure, and the triangular pressure bearing blocks 3 - 1 are rotated in sequence by preset angles on the counterweight shaft 3 in a circumferential array arrangement according to the height of the ladder.

[0050] The hydraulic energy storage and energy release adaptive control system provided by the present invention has an energy storage valve module 8 that controls the water inlet of the cylinder 1, an energy release valve module 9 that controls the water outlet of the cylinder 1, and a piston plate 2 that rises and falls according to the water volume at the bottom of the cylinder 1. A laser rangefinder 7 measures the height position of the piston plate 2 and sends it to a controller 6. The controller 6 calculates the hydraulic energy storage capacity based on the received height position data of the piston plate 2, and controls the driving mechanism 5 to drive the counterweight shaft 3 to rotate horizontally according to the hydraulic energy storage capacity, thereby changing the connection relationship between the pressure receiving block 3-1 and the counterweight block 4-1, thereby changing the number of counterweight blocks 4-1 pressed on the counterweight shaft 3, and realizing automatic adjustment of the hydraulic energy storage mass block to adjust the energy storage limit. This solves the technical problems of the existing piston-type hydraulic energy storage system in that the mass block weight cannot be automatically and adaptively adjusted according to the liquid volume in the container, and its energy storage limit is fixed at the factory, the energy storage limit is single and cannot be adjusted, the degree of automation is low, and the real-time adjustability is poor.

[0051] In one embodiment, Figure 6 As shown, the drive mechanism 5 includes a forward and reverse motor 5-1, a first bevel gear 5-2, and a second bevel gear 5-3.

The second bevel gear 5-3 is rotatably mounted on the top of the piston plate 2. The second bevel gear 5-3 is fixedly connected to the bottom of the counterweight shaft 3. Under the drive of the forward and reverse motor 5-1, the first bevel gear 5-2 rotates vertically and the second bevel gear 5-3 rotates horizontally. The forward and reverse rotation of the forward and reverse motor 5-1 drives the clockwise and counterclockwise rotation of the first bevel gear 5-2. The second bevel gear 5-3 meshes with the first bevel gear 5-2. The rotation of the first bevel gear 5-2 drives the rotation of the second bevel gear 5-3, thereby driving the counterweight shaft 3 to rotate forward and reverse.

[0052] In one embodiment, Figure 7As shown, the energy storage valve module 8 includes an inlet pipe 8-3, a first control motor 8-1, and an inlet valve 8-2. One end of the inlet pipe 8-3 is connected to the water inlet of the cylinder 1. The inlet valve 8-2 is provided on the inlet pipe 8-3. The inlet valve 8-2 is electrically connected to the first control motor 8-1, which is connected to the controller 6. The first control motor 8-1 is used to control the opening and closing of the inlet valve 8-2. The first control motor 8-1 is a linear motor. The output end of the first control motor 8-1 is connected to the valve handle, which is connected to the valve switch. The first control motor 8-1 controls the valve switch by pushing the handle. The energy release valve module 9 has the same structure as the energy storage valve module 8. It includes an outlet pipe, a second control motor, and an outlet valve. One end of the water outlet pipe is connected to the water outlet of the cylinder 1. A water outlet valve is provided on the water outlet pipe.

Wind forces cause four horizontal mounting rods 11-5 to rotate horizontally, driving vertical mounting rods 11-4 to rotate and transmit power to second power generation module 11-6, generating electricity that is then stored in power storage module 11-3. Specifically, power storage module 11-3 is electrically connected to first power generation module 11-2, second power generation module 11-6, controller 6, and drive mechanism 5. The electricity generated by first and second power generation modules 11-2 and 11-6 is stored in power storage module 11-3, which then supplies power to controller 6 and drive mechanism 5.
