Description

TECHNICAL FIELD

[0001] The present application relates to the field of liquid flow energy storage batteries, and more particularly to a container liquid flow energy storage system. BACKGROUND

[0002] The core of the liquid flow energy storage battery is to store energy in active substances (such as vanadium ions) dissolved in liquid electrolyte. This large electrochemical device realizes energy storage and release through the circulation of electrolyte between the storage tank and the stack. The system is composed of two independent liquid storage tanks, an electrode-containing stack and a key ion exchange membrane, and a circulating pump. During charging, external electrical energy is input into the stack to drive the oxidation-reduction reaction of the active substance, converting electrical energy into chemical energy for storage. When discharging, the stored chemical energy drives the reverse reaction to generate electrical energy output. Most existing liquid flow energy storage systems use two tanks for positive and negative electrodes, which are then connected to the stack system. For example, a large-capacity liquid flow battery storage device disclosed in application No. 202411786662.6; a liquid flow battery system and battery storage tank disclosed in application No. 201210056897.0. The number of storage tanks in the above prior art is 2, the capacity is limited, and the temperature fluctuation range that can be stably tolerated needs to be improved. If the capacity is increased, very complex connecting pipelines are needed, and the pipelines are prone to misconnection or missed connection during assembly, affecting assembly efficiency and convenience.

[0003] Secondly, in order to facilitate the connection and convenient installation of the electrolyte inside the storage tank, the existing method uses a corrugated pipe for connection. The corrugated pipe has a multi-angle effect, so even if there is a deviation in the connection distance and position of the two ends, it can still be reliably connected. However, due to the flexibility of the corrugated pipe, when the electrolyte enters the inside of the corrugated pipe, the weight increases, causing the corrugated pipe to locally collapse downward. Long-term use can also affect the reliability of the connection of the two ends of the corrugated pipe.

[0049] As Figure 1 - Figure 12 shown:

[0050] The embodiment provides a container liquid flow energy storage system, which comprises a stack system (not shown) and a container 1, a positive tank group 2 and a negative tank group 3 are arranged in the container 1, the positive tank group 2 is connected with the stack system through a positive liquid inlet pipe 4 and a positive liquid return pipe 5, the negative tank group 3 is connected with the stack system through a negative liquid inlet pipe 6 and a negative liquid return pipe 7, the positive tank group 2 comprises two positive tank bodies 21, a positive liquid inlet inner pipe 211 and a positive liquid return inner pipe 212 are arranged in the positive tank body 21, the positive liquid inlet pipe 4 is communicated with the positive liquid inlet inner pipe 211 in the two positive tank bodies 21 through a positive liquid inlet three-way pipe 41 respectively, and the positive liquid return pipe 5 is communicated with the positive liquid return inner pipe 212 in the two positive tank bodies 21 through a positive liquid return three-way pipe 51 respectively; the negative tank group 3 comprises two negative tank bodies 31, a negative liquid inlet inner pipe 311 and a negative liquid return inner pipe 312 are arranged in the negative tank body 31, the negative liquid inlet pipe 6 is communicated with the negative liquid inlet inner pipe 311 in the two negative tank bodies 31 through a negative liquid inlet three-way pipe 61 respectively, and the negative liquid return pipe 7 is communicated with the negative liquid return inner pipe 312 in the two negative tank bodies 31 through a negative liquid return three-way pipe 71 respectively.

[0051] Specifically, the positive liquid inlet pipe 4, the positive liquid return pipe 5, the negative liquid inlet pipe 6 and the negative liquid return pipe 7 form a positive liquid inlet connecting pipe 42, a positive liquid return connecting pipe 52, a negative liquid inlet connecting pipe 62 and a negative liquid return connecting pipe 72 connected with the stack system respectively, and the positive liquid inlet connecting pipe 42, the positive liquid return connecting pipe 52, the negative liquid inlet connecting pipe 62 and the negative liquid return connecting pipe 72 are vertically and parallelly arranged on the top of one side of the container.

[0052] Further, in order to ensure the liquid level degree of the two positive tank bodies 21, the two positive tank bodies 21 are communicated through a first balance pipe 22, and a valve is arranged on the first balance pipe 22; in order to ensure the liquid level degree of the two negative tank bodies 31, the two negative tank bodies 31 are communicated through a second balance pipe 32, and a valve is arranged on the second balance pipe 32; in order to ensure the liquid level degree of the positive tank body 21 and the negative tank body 31, adjacent positive tank bodies 21 and negative tank bodies 31 are communicated through a third balance pipe 8, and a valve is arranged on the third balance pipe 8, the valve on the balance pipe is used for internal communication and separation of the storage tank in the embodiment, the liquid level degree of multiple storage tanks can be adjusted after communication, and the function and stability between the tank bodies are not affected after separation, and the first balance pipe 22, the second balance pipe 32 and the third balance pipe 8 are close to the inner side wall surface of the container.

[0053] Specifically, the positive magnetic force pump 23 is installed between the two positive tank bodies 21 and connected between the positive liquid inlet pipe 4 and the positive liquid inlet three-way pipe 41. The positive magnetic force pump 23 is used to drive the electrolyte in the two positive tank bodies 21 to flow through the positive liquid inlet inner pipe 211, the positive liquid inlet three-way pipe 41, the positive liquid inlet pipe 4, the positive liquid inlet connecting pipe 42 into the stack system, and drive the positive electrolyte to flow through the positive liquid return connecting pipe 52, the positive liquid return pipe 5, the positive liquid return three-way pipe 51, the positive liquid return inner pipe 212 back to the two positive tank bodies 21 to form a circulation.

[0054] Further, as shown in Figure 6 The positive liquid inlet inner pipe 211 and the negative liquid inlet inner pipe 311 are connected to the liquid distribution pipes arranged at the bottom of the positive tank body 21 and the negative tank body 31. The liquid distribution pipes are provided with horizontal small holes for liquid inlet. The specific liquid flow direction is shown by the arrows in Figure 6 The electrolyte enters the liquid distribution pipe from the small holes, and then enters the positive liquid inlet inner pipe 211 and the negative liquid inlet inner pipe 311. The liquid distribution pipe is located at the lower layer, and the positive liquid return inner pipe 212 and the negative liquid return inner pipe 312 are located at the upper layer by the lower liquid outlet and upper liquid return mode, thereby ensuring the uniformity of the electrolyte use.

[0055] In this embodiment, the container 1 contains two containers and is located on the same side of the stack system. Since the positive liquid inlet connecting pipe 42, the positive liquid return connecting pipe 52, the negative liquid inlet connecting pipe 62, and the negative liquid return connecting pipe 72 connected to the stack system are all located at the top of one side of the container, if further increasing the system capacity is needed, only the number of the same configuration container 1 needs to be increased. For example, when the number of the container 1 is configured as four, it can be set as two groups, each group being the configuration in this embodiment and being symmetrically arranged on both sides of the stack system. In this way, the connection distance with the stack system is the closest, which is convenient for installation and maintenance with the stack system. Through the connection of multiple containers with the stack system, the system capacity is greatly improved, and the resistance to extreme environment is outstanding. It can stably withstand a wide temperature fluctuation of -40℃ to 50℃. Even in the local temperature difference environment caused by electrolyte circulation, it can still maintain structural stability, ensuring the continuous operation of the energy storage system under complex climate conditions.

[0056] Specifically, the positive liquid inlet tee pipe 41, the positive liquid return tee pipe 51, the negative liquid inlet tee pipe 61, the negative liquid return tee pipe 71, the first balance pipe 22, the second balance pipe 32 and the third balance pipe 8 all comprise horizontally arranged corrugated pipes, which can improve the connection adaptability of both ends of the pipes, and even if there is axial or radial movement, it will not affect the stable connection. However, the corrugated pipes are horizontally arranged and have flexibility, and when there is electrolyte inside the corrugated pipes, a collapse phenomenon will occur. In order to avoid the collapse of the corrugated pipes, supports 9 are fixed on the inner side walls of the container 1 for supporting the corrugated pipes. The support 9 comprises a mounting seat 91 fixed on the inner side wall of the container 1 and a height adjusting seat 92 movably connected to the mounting seat 91 through a height adjusting mechanism 10. A horizontal sliding plate 93 is mounted on the height adjusting seat 92 through a horizontal adjusting mechanism 11. A pipe holder 94 for holding the corrugated pipe is fixed to the front end of the horizontal sliding plate 93. An upper clamping plate 95 and a lower clamping plate 96 are respectively hinged to the upper end and the lower end of the pipe holder 94. The pipe holder 94, the upper clamping plate 95 and the lower clamping plate 96 limit the corrugated pipe through a quick locking mechanism 12.

[0057] Further, in order to facilitate the axial movement of the corrugated pipe, the inner side upper end of the pipe holder 94 is a smooth arc surface, and a through groove 941 is formed in the pipe holder 94. The inner sides of the upper clamping plate 95 and the lower clamping plate 96 are provided with positioning ribs 97 which are in line with the outer ring grooves of the corrugated pipe.

[0058] In use, the corrugated pipe is placed in the pipe holder 94, the axial position of the corrugated pipe is adjusted, then the upper clamping plate 95 is turned down, the positioning rib 97 enters the outer ring groove of the corrugated pipe, then the lower clamping plate 96 is rotated upwards, the front end of the positioning rib 97 passes through the through groove 941 and enters the outer ring groove of the corrugated pipe. At this time, the upper clamping plate 95 forms radial and axial constraints on the corrugated pipe, but does not exert radial clamping force. In this embodiment, the positioning rib 97 cooperates with the outer ring groove of the corrugated pipe to achieve positioning, and also has the effects of buffering and preventing deformation, ensuring reliable use of the corrugated pipe.

[0059] Specifically, the height adjusting mechanism 10 comprises adjusting grooves 101 and hanging grooves 102 formed on the mounting seat 91, and a baffle 103 fixed on the side of the height adjusting seat 92 and located outside the mounting seat 91 through bolts. The inner side of the baffle 103 is formed with an adjusting sleeve 104 movably arranged in the adjusting grooves 101 and the hanging grooves 102. The adjusting grooves 101 and the hanging grooves 102 are provided to facilitate quick height adjustment. In order to avoid the adjusting sleeve 104 from being separated from the hanging grooves 102, the hanging grooves 102 are arranged in an inclined downward manner, and then the gravity synchronously prevents falling.

[0060] In use, the height adjusting seat 92 is lifted, the adjusting sleeve 104 is slid in the adjusting grooves 101, and after the required height is adjusted, the adjusting sleeve 104 is placed in the hanging grooves 102. At this time, the rear end and both sides of the height adjusting seat 92 are completely in contact with the inner side of the mounting seat 91.

[0061] A limiting bolt 105 is threadedly connected to the baffle 103, and a limiting hole 106 is formed in the outer side of the mounting seat 91 to be inserted and matched with the limiting bolt 105;

[0062] When the position of the height adjusting seat 92 needs to be adjusted, the limiting bolt 105 is completely separated from the limiting hole 106, so as to facilitate quick adjustment. When the adjusting sleeve 104 is located in the hanging groove 102, that is, after the adjustment is completed, the limiting bolt 105 is screwed at this time, and the front end of the limiting bolt 105 is inserted into the limiting hole 106 through the thread between the limiting bolt 105 and the baffle 103, so as to realize the locking after the height adjustment. This locking mode has the advantages of simple structure, convenient operation and high reliability.

[0063] Specifically, the horizontal adjusting mechanism 11 is formed by a sliding sleeve 111 in the inner side of the height adjusting seat 92 and symmetrical clamping grooves 112 formed in the inner side wall of the sliding sleeve 111. The horizontal sliding plate 93 is provided with a clamping block 113 on the side surface to be inserted and matched with the clamping groove 112. In this embodiment, the horizontal sliding plate 93 horizontally slides in the sliding sleeve 111. In order to be able to position at multiple positions after horizontal adjustment, the clamping groove 112 is provided with a plurality of horizontal parallel clamping grooves. In order to facilitate the insertion of the clamping block 113 and the clamping groove 112, the insertion ends of the two are provided with matching chamfers.

[0064] The clamping block 113 is fixed with an internal thread sleeve 114 sliding in the horizontal sliding plate 93. The horizontal sliding plate 93 is provided with a rotating bidirectional screw rod 115 which is threadedly matched with the internal thread sleeve 114. The bidirectional screw rod 115 also penetrates the clamping block 113 and extends to the outer side of the sliding sleeve 111.

[0065] In use, one end of the bidirectional screw rod 115 extending outward is provided with a knob for manual operation. The knob is used to rotate the bidirectional screw rod 115 in the horizontal sliding plate 93. At this time, the internal thread sleeve 114 drives the clamping blocks 113 at both ends to slide inward or outward through the screw of the bidirectional screw rod 115. The bidirectional screw rod 115 is counterclockwise rotated. The internal thread sleeve 114 drives the clamping block 113 to be separated from the clamping groove 112 through the screw of the bidirectional screw rod 115. The clamping block 113 can freely slide horizontally in the sliding sleeve 111. The sliding sleeve 111 is provided with a slot on the side surface for the sliding of the bidirectional screw rod 115. The bidirectional screw rod 115 is clockwise rotated. The internal thread sleeve 114 drives the clamping block 113 to be inserted into the clamping groove 112 through the screw of the bidirectional screw rod 115. The clamping block 113 is fixed on the sliding sleeve 111. In this embodiment, two symmetrical clamping blocks 113 and two rows of clamping grooves 112 are provided to ensure uniformity of stress and avoid shaking. The mode adopted in this embodiment has the advantages of convenient operation and reliable structure.

[0066] Specifically, the quick locking mechanism 12 comprises a locking rod 121 hinged to the lower clamping plate 96, the locking rod 121 can slide axially along the hinge, the pipe support 94 and the upper clamping plate 95 are both provided with a movable slot 126 at the same end, the movable slot 126 is provided with a locking slot 127 corresponding to the axial sliding of the locking rod 121, the locking rod 121 enters the locking slot 127 after sliding axially in the movable slot 126, the locking slot 127 is used to limit the rotation of the locking rod 121 on the lower clamping plate 96, further, the locking rod 121 is fixed with a cross rod 122, the cross rod 122 is penetrated by a sliding rod 124, the bottom of the sliding rod 124 is fixed with a locking block 125, the locking block 125 and the cross rod 122 are provided with a spring 123 abutting, the locking block 125 enters the movable slot 126 and blocks the locking rod 121 in the locking slot 127 through the spring 123;

[0067] In use, the locking rod 121 is rotated to correspond to the movable slot 126, and the sliding rod 124 is pulled upward first, at this time, the spring 123 is compressed, the locking block 125 moves upward, when the locking rod 121 enters the locking slot 127, the sliding rod 124 is released, and the locking block 125 can be inserted into the movable slot 126 under the action of the spring 123, so as to block the disengagement direction of the locking rod 121, for final positioning, this positioning mode is simple in structure, convenient to operate, and can achieve significant positioning effect, in the embodiment, in order to facilitate the upward pulling of the sliding rod 124, a handle, a pull rod or the like can be arranged at the upper end of the sliding rod 124.
