Description

Technical Field

[0001] The invention relates to the technical field of compressed air energy storage equipment, in particular to a compressed air energy storage equipment capable of predicting wave intensity. Background Art

[0002] Compressed air energy storage can effectively store intermittent renewable energy such as wind and solar energy, reduce energy waste, and improve the utilization rate of renewable energy. By storing energy when the grid load is low and releasing it at peak times, compressed air energy storage helps improve the peak load and frequency regulation performance of the grid and enhance the flexibility and reliability of the grid.

[0003] The existing application number is CN201310155855.7. The patent document discloses a scheme of combining a constant pressure gas storage device and a variable pressure gas storage device. By measuring the pressure of the circulating medium and maintaining its constant pressure, constant power output is achieved. Specifically: during the low power consumption period, air is compressed into the constant pressure gas storage device through a compressor unit, and at the same time, the liquid in the constant pressure gas storage device is compressed into the variable pressure gas storage device through a liquid pump, so that the electrical energy is converted into the internal energy of the air and liquid and stored; during the peak power consumption period, the high-pressure air in the constant pressure gas storage device absorbs heat through the heater and drives the generator to generate electricity through the expander, and at the same time, the high-pressure fluid in the variable pressure gas storage device drives the hydraulic motor generator set to generate electricity, and the fluid is injected into the constant pressure gas storage device to maintain its constant pressure; the constant pressure compressed air energy storage and hydraulic energy storage are combined, and the pressure in the constant pressure gas storage device is kept constant by controlling the volume of the liquid in the constant pressure gas storage device, so that the compressor unit and the expander unit of the energy storage system always work stably at the rated pressure during the energy storage state and the energy release process;

[0004] When using the technical solution in the above patent document, the purpose of energy storage is achieved by compressing air and liquid with unused electricity during low electricity consumption. Although excess electricity can be effectively utilized, when the low electricity consumption lasts for a long time, more containers are needed to store the compressed air and liquid, which not only takes up a large space, but also requires a relatively high number of compression drive devices, resulting in a significant increase in the overall cost of the energy storage system. Therefore, the present application provides a compressed air energy storage device that can predict wave intensity. Summary of the invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The compressed air energy storage device capable of predicting wave strength in the example of the present invention, during the reciprocating swing of the V-shaped seat, the two connecting rods respectively control the two pistons to perform alternating lifting and lowering movements in the air purification tank and the air compression tank, and implement air intake and air compression and discharge operations by periodically opening and closing the valves on the pipe II, the air bleed pipe and the compressed air outlet pipe. Since the equipment is installed under the sea surface, it will not occupy the building area on the surface, saving floor space. Compared with the compressors used on a large scale in the comparative documents, the use of the technical solution of the present application can reduce the demand for compression drive equipment, thereby reducing the overall cost of the energy storage equipment.

[0024] 2. The compressed air energy storage device capable of predicting wave intensity in the example of the present invention has a large contact area between the side of the V-shaped seat and the seawater, and the energy density of the waves increases with the increase of wave height and wave period. When the wave contacts the V-shaped seat, it will transfer its kinetic energy to the V-shaped seat, and the V-shaped seat will be moved back and forth to realize full-time air compression energy storage. Combined with the use of high-pressure air to drive the turbine, it can share the pressure of the power plant during peak power consumption, effectively reduce the difference between excess power during peak power consumption and low power consumption, reduce the pressure on the power supply station, and reduce the waste of resources caused by excess power.

[0025] 3. The compressed air energy storage device capable of predicting wave intensity in the example of the present invention uses a heating rod to evaporate the moisture adsorbed by the filter cloth; uses a sponge cover to adsorb the moisture in the air flowing through the air duct; uses an air filter component to squeeze out the moisture inside the sponge cover. Combining the above-mentioned multiple schemes, the moisture in the air entering the equipment can be effectively reduced, thereby reducing the interference with the continuous operation of the equipment.

[0026] 4. The compressed air energy storage device capable of predicting wave strength in the example of the present invention has floating plates installed on both sides of the V-shaped seat. When there is no external force, the opening of the V-shaped seat faces upward, and the angles between the two sides of the bottom of the V-shaped seat and the horizontal plane are at the same state. The waves on either side of the V-shaped seat can exert a swinging force on the V-shaped seat. As the waves weaken, the V-shaped seat returns to the state of opening upward, forming a swing cycle of the V-shaped seat, realizing synchronous and continuous operation of air intake and air compression and discharge, and has good adaptability.

[0027] 5. The compressed air energy storage device capable of predicting wave intensity in the example of the present invention utilizes the characteristic that the intensity of waves directly affects the swing speed and frequency of the V-shaped seat, uses a pressure gauge and a flow meter to monitor and record the air compression over a period of time, thereby realizing the prediction operation of wave intensity. When the wave intensity exceeds the threshold, the operation of the equipment is stopped and the people on the shore are warned.

[0028] 6. The compressed air energy storage device capable of predicting wave intensity in the example of the present invention uses multiple energy storage modules to intercept waves. When the floating swing component rotates to the state shown in the figure, all valves in the system are closed to make the floating swing component maintain a state in which one end is horizontal and the other end is raised. Under the action of multiple floating swing components, the waves are effectively intercepted, the impact damage of the waves on the embankment is reduced, and the safety of people and property is prevented from being damaged.

[0046] Embodiment 1:

[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a compressed air energy storage device capable of predicting wave strength, including a base 1, an underwater air storage component 2, a sea surface extension component 3, a floating swing component 4, an air inlet component 5 and an air filter component 6; the base 1 is erected on the seabed, the underwater air storage component 2 is installed on the base 1, the sea surface extension component 3 is fixedly installed on the top outer side of the underwater air storage component 2, the floating swing component 4 is movably installed in the sea surface extension component 3, and the air inlet component 5 is connected to the underwater air storage component 2.

[0048] Among them, the base 1, the underwater air storage component 2, the floating swing component 4, the air inlet component 5 and the air filter component 6 constitute an energy storage module. There are multiple energy storage modules, and multiple energy storage modules are installed on the sea surface extension component 3 at equal intervals. Different numbers of energy storage modules are enabled to cope with different electricity demands.

[0049] like Figure 2 and Figure 7 As shown, the underwater air storage component 2 includes an air purification tank 21 and an air compression tank 22; the air purification tank 21 and the air compression tank 22 are connected by pipes I 23, II 24 and III 25, the bottom outer side of the air purification tank 21 is connected by a drain pipe 211, and the side of the air compression tank 22 is connected by a compressed air outlet pipe 221, which is connected to the compressed air storage tank and the high-pressure air-driven turbine through a three-way connector to store compressed air or convert fluid energy into mechanical energy.

[0050] like Figure 2 , Figure 3 and Figure 5 As shown, the sea surface extension component 3 includes a supporting seat 31, and at least two supporting seats 32 are fixedly installed on the upper side of the supporting seat 31; the floating swinging component 4 includes an axle seat 41, a V-shaped seat 42 rotatably installed on the axle seat 41, and floating plates 43 installed on both sides of the inside of the V-shaped seat 42; the axle seat 41 is detachably fixedly installed between two adjacent supporting seats 32, and connecting rods 46 are rotatably installed on both sides of the bottom of the V-shaped seat 42, and the other end of the connecting rod 46 is rotatably connected to a lifting column 47, and a piston 472 is fixedly installed on the bottom of the lifting column 47, and the two pistons 472 are slidingly connected to the air purification tank 21 and the air compression tank 22 respectively.

[0051] Among them, the tops of the two pistons 472 and the areas enclosed by the air purification tank 21 and the air compression tank 22 constitute compression chamber I and compression chamber II. Compression chamber I and compression chamber II are connected to each other through tube I 23 to ensure the synchronous and smooth reciprocating rise and fall of the two pistons 472. Compressed air or hydraulic oil can be stored in compression chamber I and compression chamber II.

[0052] like Figure 3 and Figure 4 As shown, slopes 44 are respectively provided at both ends of the V-shaped seat 42, and a plurality of guide grooves 45 are provided on the slopes 44; the slopes 44 can reduce the resistance of the edge of the V-shaped seat 42 to the flow of seawater when the V-shaped seat 42 swings to one side horizontally, and the guide grooves 45 can buffer the impact force exerted by strong waves on the side of the V-shaped seat 42 when it swings to the raised side, thereby ensuring the continuous and stable operation of the V-shaped seat 42.

[0053] like Figure 2 , Figure 5 and Figure 7 As shown, the air bleed component 5 includes an air bleed pipe 51, the end of which extends above the sea surface; the drain pipe 211, pipe II 24, pipe III 25 and the air bleed pipe 51 are respectively provided with at least one valve, which includes a stop valve, a one-way valve and a safety valve.

[0054] In the present application, the valves on the drain pipe 211 and the pipe III 25 are normally closed and are opened only when it is necessary to discharge the liquid accumulated at the bottom of the air purification tank 21 or the air compression tank 22; when it is necessary to discharge the liquid accumulated at the bottom of the air purification tank 21, the valves on the pipe II 24, the pipe III 25 and the air duct 51 are closed, and the valve on the drain pipe 211 is opened. When the piston 472 in the air purification tank 21 moves downward, the liquid accumulated at the bottom of the air purification tank 21 is discharged to the outside of the air purification tank 21 through the drain pipe 211; using the above scheme, the moisture contained in the air can be reduced during the period when the air passes through the air purification tank 21 and then enters the air compression tank 22.

[0055] In the present application, in addition to the stop valve and the one-way valve installed on the compressed air outlet pipe 221, a pressure gauge and a flow meter are additionally provided to predict the intensity of the waves. Specifically: since the intensity of the waves will directly affect the swing speed and the swing frequency of the V-shaped seat 42, the pressure gauge and the flow meter are used to monitor and record the air compression over a period of time, so as to realize the prediction operation of the wave intensity. When the wave intensity exceeds the threshold, the operation of the equipment is stopped and the people on the shore are warned.

[0056] When multiple energy storage modules are used to intercept waves, the floating swing component 4 rotates to Figure 1When the floating swing component 4 is in the middle state, all valves in the system are closed, so that one end of the floating swing component 4 is kept horizontal and the other end is raised. Under the action of multiple floating swing components 4, the waves are effectively intercepted, the impact damage of the waves on the embankment is reduced, and the safety of personnel and property is avoided.

[0057] The details of air compression using the compressed air energy storage device of this application are as follows:

[0058] The device is installed in a sea area near the shore. In the absence of wind and waves, under the action of the floating plates 43 on both sides of the V-shaped seat 42, the opening of the V-shaped seat 42 faces upward, and the angles between the two sides of the bottom of the V-shaped seat 42 and the horizontal plane are in the same state;

[0059] As the waves surge, the waves drive the V-shaped seat 42 to swing back and forth. Under the action of the two connecting rods 46, the two pistons 472 are controlled to alternately move up and down in the air purification tank 21 and the air compression tank 22, respectively, and the valves on the pipe II 24, the air bleed pipe 51 and the compressed air outlet pipe 221 are periodically opened and closed to implement the operation of air intake and air compression discharge. Specifically:

[0060] by Figure 4 Taking the position of the middle V-shaped seat 42 as an example, the V-shaped seat 42 swings clockwise and then swings counterclockwise, which constitutes the entire swing cycle of the V-shaped seat 42;

[0061] When the V-shaped seat 42 swings clockwise, it drives the piston 472 in the air purification tank 21 to move upward. At this time, the valve on the air bleed pipe 51 is opened, and the valve on the pipe II 24 is closed; air is sucked into the air purification tank 21 through the air bleed pipe 51. At the same time, the piston 472 in the air compression tank 22 moves downward to compress the air pressed into the air compression tank 22 in the previous cycle. When the piston 472 moves to the limit position, the valve on the compressed air outlet pipe 221 is opened to discharge the compressed air;

[0062] When the V-shaped seat 42 swings counterclockwise, it drives the piston 472 in the air purification tank 21 to move downward. At this time, the valve on the air inlet pipe 51 is closed, and the valve on the pipe II 24 is opened; the air in the air purification tank 21 is compressed into the air compression tank 22. At the same time, the piston 472 in the air compression tank 22 moves upward to provide storage space for the air entering the air compression tank 22.

[0063] The above operation is repeated to implement multiple swing cycles of the V-shaped seat 42 to achieve synchronous and continuous operation of air intake and air compression and discharge.

[0064] In this process, since the contact area between the side of the V-shaped seat 42 and the sea water is larger, and the energy density of the waves increases with the increase of wave height and wave period, the waves will transfer their kinetic energy to the V-shaped seat 42 when contacting the V-shaped seat, and the V-shaped seat 42 will be reciprocated to realize full-time air compression energy storage. Combined with the use of high-pressure air to drive the turbine, the pressure of the power plant during peak power consumption is shared, thereby effectively reducing the difference between excess power during peak power consumption and low power consumption, reducing the pressure on the power supply station, and reducing the waste of resources caused by excess power.

[0065] Among them, since the equipment is installed under the sea surface, it will not occupy the surface building area, saving floor space. Compared with the compressors used on a large scale in the comparative documents, the use of the technical solution of the present application can reduce the demand for compression drive equipment, thereby reducing the overall cost of the energy storage equipment.

[0066] In order to prevent the inhaled air from containing debris that may affect the operation of the equipment, such as Figure 5 As shown, an air suction cylinder 53 is fixedly installed and connected to the end of the air duct 51 located on the upper side of the sea surface, and a plurality of fine small holes are provided on the side of the air suction cylinder 53 to intercept debris in the air to avoid adverse effects on the cleanliness of the inside of the equipment.

[0067] In order to facilitate the disassembly and maintenance efficiency of the V-shaped seat 42, as Figure 4 and Figure 5 As shown, plugs 411 are respectively provided on both sides of the shaft seat 41, and a slot 33 is provided on the supporting seat 32. The plug 411 is detachably fixedly installed in the slot 33 by fasteners, and the articulated seat I 421 and the articulated seat II 471 are rotatably installed at both ends of the connecting rod 46, and the articulated seat I 421 and the articulated seat II 471 are detachably fixedly installed on the V-shaped seat 42 and the lifting column 47; by utilizing the docking connection of the plug 411 and the slot 33, combined with the detachable design of the articulated seat I 421 and the articulated seat II 471, the shaft seat 41 and the V-shaped seat 42 can be quickly removed together.

[0068] In addition, since the articulated seat I 421 and the articulated seat II 471 can be detachably installed on the V-shaped seat 42 and the lifting column 47, by adjusting the position of the articulated seat I 421 on the V-shaped seat 42, the distance between the rotation center of the V-shaped seat 42 and the shaft seat 41 is changed, and the movement limit of the lifting column 47 that can be driven by the V-shaped seat 42 rotating to a specified angle is adjusted, the equipment operation efficiency can be adjusted.

[0069] Embodiment 2:

[0070] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 7As shown, in this embodiment, an air filter component 6 is installed at a position corresponding to the air duct 51 on the inner side of the air purification tank 21, which is used to further remove moisture from the air entering the air duct 51. The specific structure is as follows:

[0071] The air filter component 6 includes a screw 61 and a fixing seat 64, which are respectively fixedly mounted on the bottom of the piston 472 and the inner side of the air purification tank 21. The outer side of the screw 61 is connected with an internal threaded sleeve 621 through a threaded transmission. The internal threaded sleeve 621 is fixedly mounted on the inner side of a rotating drum 62. The rotating drum 62 is rotatably connected to an inner ring 65 on the fixing seat 64, and a plurality of air holes 622 are arranged on the side of the rotating drum 62.

[0072] like Figure 8 and Fig. 9 As shown, a sponge cover 63 is fixedly installed on the outer side of the rotating drum 62, and the sponge cover 63 is used to absorb moisture in the air flowing through the air duct 51. A plurality of convex ridges 66 are installed on the fixed seat 64; as the rotating drum 62 and the sponge cover 63 rotate synchronously, the plurality of convex ridges 66 alternately apply extrusion force to the sponge cover 63 to squeeze out the water in the sponge cover 63.

[0073] When the piston 472 rises in the air purification tank 21, the negative pressure environment in the air purification tank 21 is used to allow the air above the sea surface to enter the air bleed pipe 51, and then this part of the air is intercepted by the sponge cover 63, and the moisture inside is absorbed by the sponge cover 63, and the dry air enters the air compression tank 22 through the multiple air holes 622 and the pipe II 24;

[0074] At the same time, the screw 61 rises together with the piston 472, and the threaded transmission between the screw 61 and the internal threaded rotating sleeve 621 drives the rotating drum 62 and the sponge cover 63 to rotate together. Under the action of multiple ridges 66, the moisture inside the sponge cover 63 is squeezed out, so that the sponge cover 63 is restored to a dry state for subsequent air drying and dehydration treatment.

[0075] In order to ensure that the opening of the V-shaped seat 42 can remain facing upward in the absence of wind and waves, the weights of the two pistons 472 are adjusted to avoid unbalanced resistance during the reciprocating swing of the V-shaped seat 42 due to the use of the air filter component 6.

[0076] Embodiment three:

[0077] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 7 As shown, in this embodiment, the tops of the air compression tank 22 and the air purification tank 21 are flush, and the bottom of the air compression tank 22 is higher than the bottom of the air purification tank 21; the tube III 25 is tiltedly arranged between the air compression tank 22 and the air purification tank 21.

[0078] Open the valve on tube III 25, close the valves on tube II 24 and the compressed air outlet pipe 221. As the piston 472 moves downward in the air compression tank 22, the internal pressure of the air compression tank 22 increases, thereby pushing the liquid gathered at the bottom of the air compression tank 22 into the air purification tank 21 for subsequent discharge, thereby ensuring the internal dryness and stable operation of the equipment.

[0079] Embodiment 4:

[0080] The features of this embodiment that are the same as those of the first embodiment are not described in detail.
