Description

Technical Field

[0001] The present invention relates to the technical field of power station battery packs, and in particular to an energy storage power station capable of preventing battery overheating. Background Art

[0002] The energy storage station is an equipment system that stores, converts and releases cyclic electric energy through electrochemical batteries or electromagnetic energy storage media. One of the core functions of the energy storage station is to store and release energy according to the needs of the power grid to balance the supply and demand of electricity. When the input power changes, the control system of the energy storage station will adjust its charging and discharging power according to the preset program or remote command to maintain the stability of the power grid. For example, when there is excess power generation in the power grid, the energy storage station will increase the charging power to store excess power; when the demand of the power grid increases, the energy storage station will increase the discharge power to supplement the power supply of the power grid. The energy storage station is equipped with a battery pack. Due to the change of the input power of the power station, when the power is too large, the battery will quickly generate heat during the charging and discharging process, resulting in changes in the battery temperature. The temperature of the battery pack has an important impact on its performance and life. If the heat dissipation problem cannot be effectively solved, the high temperature of the environment will reduce the charging and discharging efficiency of the battery, and in severe cases, it will cause the battery to burn, thereby causing a series of power station safety accidents. In order to achieve cooling control of the temperature of the battery assembly, the present invention provides an energy storage station that can avoid battery overheating. Summary of the invention

In addition, a row of batteries in the battery pack are supplied with cold water in turn. After the cold water wraps the battery, it will be retained for a period of time, thereby ensuring that the cold water can fully absorb the heat in the battery and improve the utilization of cold water, which is in line with the concept of energy conservation and emission reduction of the energy storage power station.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 technical solutions in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 16The present invention provides a technical solution: an energy storage power station capable of preventing battery overheating, comprising a power station box 1, a battery pack 2 being arranged in the power station box 1, the battery pack 2 comprising a main frame 3, a row of roller tracks 4 fixed on the main frame 3, a battery 5 placed on each roller track 4, a line integration device 6 in conductive contact with the row of batteries 5, a water supply integration 7 for supplying water and cooling the row of batteries 5, a drainage integration 8 for draining water from the row of batteries 5, a unit power integration 9 for driving and applying pressure on one side of each battery 5, and a bottom frame rail body 10 fixed at the bottom end of each battery 5, the bottom frame rail body 10 and the drainage integration 8 are connected, a row of sockets are arranged on the line integration device 6, and the battery 5 is plugged into the socket on the line integration device 6 by setting a plug, a square cylindrical cavity layer for water flow to pass through is opened in the outer square cylinder shell of the battery 5, a row of horizontal concave folding diverter sheets 11 are arranged in the cavity layer, and a A vertical long piece 12 is used to separate the water inlet end and the water outlet end. An upper neck tube 13 connected to the water inlet end of the cavity layer and a lower neck tube 14 connected to the water outlet end of the cavity layer are fixed on the battery 5 shell. There is a water diversion channel between the two concave diversion pieces 11. An interception wall panel can be set at the water inlet of the channel. A guide plate hole is opened on the wall panel to assist in the diversion of water entering the cavity layer of the battery 5 shell. In this way, the water flow flows evenly in the battery 5 shell in a closed loop and then is discharged to evenly take away the heat emitted from the battery 5. Here, the shell of the battery 5 is innovatively developed and transformed. The other structures in the battery 5 are existing technology products. In addition, the plug, socket and line integrated device 6 are all existing technology devices. When the battery 5 moves away from the water supply integrated device 7 and the drainage integrated device 8 under the pressure of the unit power integrated device 9, the plug will be directly pulled out of the socket, and then the battery 5 and the line integrated device 6 are powered off and separated.

[0036] refer to Figure 8 It is understood that the water supply integration 7 includes a square cylindrical water pipe 16 in contact with a row of upper neck tubes 13, an integrated worm 17 arranged in the square cylindrical water pipe 16, a row of internal adjustment parts 19 driven on the integrated worm 17, and a first one-way valve 18 corresponding to each internal adjustment part 19. A circular hole is opened on the shell of the square cylindrical water pipe 16 between the first one-way valve 18 and the upper neck tube 13, and the internal channel of the first one-way valve 18 is pushed open by fixing the T-frame 15 in the upper neck tube 13. The outside of the square cylindrical water pipe 16 is padded between the upper neck tube 13 and the square cylindrical water pipe 16 by fixing a rubber sealing ring plate. One end of the square cylindrical water pipe 16 is a blocking shell, and one end of the integrated worm 17 passes through the blocking shell of the square cylindrical water pipe 16, and the end of the integrated worm 17 is externally connected to the motor drive mechanism in the prior art, and the other end of the square cylindrical water pipe 16 is externally connected to the cold water supply mechanism in the prior art.

[0037] refer to Fig.10It is understood that the internal adjustment part 19 includes a sub-frame 24 fixed in the square tube water pipe 16, a sub-shaft 22 supported on the sub-frame 24, a dial 23 fixed at one end of the sub-shaft 22, a pressure group 21 contacted and driven by the dial 23, and a door panel 20 transmission-connected to the pressure group 21. The sub-frame 24 also supports and positions the integrated worm 17. One end of the door panel 20 is movably sleeved in a column hole opened on the sub-frame 24 through a fixed shaft, and the other end of the door panel 20 is blocked at the pipe tube port on the first one-way valve 18. The integrated worm 17 and the sub-shaft 22 are movably sleeved in different through holes opened on the sub-frame 24.

[0038] The dial 23 includes a rotating disk and a protrusion fixed on the outer edge of the rotating disk. The sub-shaft 22 is connected to the spiral teeth on the fixed gear and the integrated worm 17 through meshing transmission. The positions of the protrusions on the dial 23 are different. Fig.12 The protrusions on a row of dials 23 are arranged in a progressively surrounding position, so that when all the dials 23 rotate synchronously, the timing of turning the pressure group 21 is different, and the subsequent transmission makes the water injection timing of each battery 5 different, that is, each battery 5 is supplied with water in turn.

[0039] refer to Fig.11 It is understood that the pressure group 21 includes a side frame 27 fixed on the sub-frame 24, a positioning shaft 25 supported on the side frame 27, a stroke amplifier 28 which contacts the edge of the dial 23 on one side, and a return spring 26 which contacts the stroke amplifier 28 on the other side. One end of the return spring 26 is fixed on the side frame 27, one end of the stroke amplifier 28 is vertically fixed to the positioning shaft 25, and the other end is connected by an arc-shaped rack and a gear meshing transmission connected to the door panel 20. The positioning shaft 25 is movably sleeved in a through hole opened on the side frame 27.

[0040] refer to Fig.13 It is understood that the drainage integration 8 includes a return water main pipe 29, a row of branch pipes 30 fixedly connected to one side of the return water main pipe 29, a branch box 32 fixedly connected to the bottom end of each branch pipe 30, and a second one-way valve 33 set in each branch box 32, each lower neck pipe 14 is in contact with the branch box 32, and a diversion circular hole is opened on the shell of the branch box 32 between the second one-way valve 33 and the lower neck pipe 14. The second one-way valve 33 and the first one-way valve 18 have the same structure and are both one-way diversion devices in the prior art. The water in the battery 5 shell is discharged through the lower neck pipe 14, the water pressure impact can directly open the internal channel of the second one-way valve 33. If the lower neck tube 14 and the support box 32 are directly separated, the channel of the second one-way valve 33 is automatically closed to prevent the water in the support box 32 from being discharged. The function of the first one-way valve 18 is also to prevent the water in the square tube water pipe 16 from being discharged. However, the T-frame 15 pushes open the internal channel of the first one-way valve 18, that is, when the battery 5 and the water supply integrated circuit 7 are normally connected and connected, the water in the square tube water pipe 16 can pass through the first one-way valve 18 and the upper neck tube 13 and then be injected into the battery 5 housing.

[0041] The drainage integration 8 also includes a deformation rod 31 and a J-shaped rod 34 that are deformed by thermal expansion. The deformation rod 31 is distributed in the branch pipe 30. One end of the deformation rod 31 contacts the J-shaped rod 34. One end of the J-shaped rod 34 slides through the inner hole of the outer cylinder fixed on the support box 32. The other end of the J-shaped rod 34 slides into the column hole opened at one end of the bottom frame rail body 10. Fig.13 The deformable rod 31 is a column that is sensitive to thermal expansion and contraction in the prior art. The hot water discharged from the battery 5 flows through the branch box 32 and the branch pipe 30 in turn, and then is discharged to the outside through the return water main pipe 29. Passing through the branch pipe 30 will affect the deformable rod 31, and the discharged water will be overheated, and the deformable rod 31 will be excessively deformed and elongated. The top of the deformable rod 31 is supported by the return water main pipe 29, and the bottom of the deformable rod 31 will push the J-shaped rod 34 downward. After the J-shaped rod 34 descends, it will no longer hook the bottom frame rail body 10, and then the battery 5 will translate.

[0042] The unit power integration 9 includes a transverse rack 39 fixed on the battery 5, a longitudinal shaft 38 with one end transmitting to the transverse rack 39, a follower shaft 36 vertically transmitting to the other end of the longitudinal shaft 38, a mainspring group 35 transmitting to the follower shaft 36, and a thin plate frame 37 for simultaneously supporting the mainspring group 35, the follower shaft 36 and the longitudinal shaft 38.

[0043] One end of the longitudinal shaft 38 is connected to the horizontal rack 39 through a meshing transmission connection via a fixed gear, and the other end of the longitudinal shaft 38 is connected to the fixed bevel gear at one end of the follower shaft 36 through a meshing transmission connection. The follower shaft 36 and the longitudinal shaft 38 are respectively movably sleeved in different through holes opened on the thin plate frame 37.

[0044] The mainspring group 35 includes a Y-shaped plate 42 fixed on the thin plate frame 37, three rollers 40 evenly arranged on the Y-shaped plate 42, a pressure ring tube 41 clamped and limited by the three rollers 40, a mainspring 43 fixed in the pressure ring tube 41, and a central fixed shaft 44 fixed in the middle of the mainspring 43, one end of the central fixed shaft 44 is fixed in the middle of the Y-shaped plate 42, the pressure ring tube 41 includes a cylinder body and a rail body ring plate fixed on one side of the cylinder body, and the other side of the cylinder body of the pressure ring tube 41 is meshed and transmission connected with the cylinder gear fixed on the follower shaft 36 by setting an external gear ring.

[0045] The integrated worm 17 drives the sub-shaft 22 during rotation, thereby controlling the rotation of the dial 23. During the process of rotating the dial 23 for one circle, there will be a stage to turn the stroke amplifier 28. After the stroke amplifier 28 swings, it drives the gear on the door panel 20 to rotate, and then the door panel 20 swings. The door panel 20 no longer blocks the first one-way valve 18, and at the same time, the T-frame 15 always opens the internal passage of the first one-way valve 18, so that the cold water in the square tube water pipe 16 is injected into the battery 5 housing, flows in the battery 5 housing for one circle, and is discharged through the lower neck pipe 14 at the bottom, and then converges to the return water main pipe 29 through the branch box 32 and the branch pipe 30, and then is discharged in a centralized manner. In a row of batteries 5, each battery 5 is supplied with water in turn. Compared with the continuous water cooling and cooling mode of the battery 5 in the traditional technology, the intermittent water supply of the present invention can ensure that the cold water fully absorbs the heat emitted from the battery 5, improves the utilization rate of the cold water, and reduces the energy consumption of the entire battery pack, which is in line with the concept of energy conservation and emission reduction.

[0046] If the water discharged from a single battery 5 is overheated, it means that there is a problem inside the battery 5, and it needs to be kicked out of the battery pack queue in time to avoid the hidden danger of overheating and combustion that endangers other batteries 5. As mentioned earlier, when the deformable rod 31 detects that the water temperature is too high, it will automatically cause the subsequent J-shaped rod 34 to not block the chassis rail body 10, so that the battery 5 can directly drive the chassis rail body 10 to translate, because the spring 43 will deform and open, thereby driving the pressure ring tube 41 to rotate. The spring 43 is kept in a contracted and tightened state during installation. The rotation of the pressure ring tube 41 drives the follower shaft 36, and then the longitudinal shaft 38 rotates to drive the horizontal rack 39 to translate. The follower shaft 36 drives the battery 5. After the battery 5 translates, it detaches from a row of batteries 5. At the beginning of the translation of the battery 5, the upper neck tube 13 and the square tube water pipe 16 are directly separated, and the lower neck tube 14 and the support box 32 are also directly separated. At the same time, the battery 5 and the line integration device 6 will also be directly separated and powered off.

[0047] Water cooling is more in line with the use requirements of power station battery packs. Water-cooled batteries use the high thermal conductivity of water to quickly dissipate heat, thereby reducing the temperature of the battery and improving the performance and life of the battery. The cooling effect of water-cooled batteries can effectively reduce the degradation of components. In addition, water itself is an environmentally friendly resource. The use of water-cooled batteries will also reduce pollution to the environment. Due to the significant cooling effect of water-cooled batteries, the energy consumption of the battery can be reduced to achieve energy conservation and emission reduction, which is based on the research and development concept of water cooling of power station battery packs.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
