[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. During normal heat dissipation, the water-cooling pipe is located in the middle between the two batteries. If the battery on one side accidentally overheats, the water-cooling pipe will move closer to the overheated battery. At the same time, the flow of cold water in the water-cooling pipe will be enhanced, thereby effectively absorbing the heat around the overheated battery. The cooling work of the battery on the other side of the water-cooling pipe will not be affected. Although the distance from the water-cooling pipe has increased, the heat absorption effect of the water-cooling pipe has been enhanced, which can offset the heat absorption problem caused by the increased distance.

[0015] 2. When the water-cooling pipe absorbs heat normally in the middle between two batteries, cold water flows intermittently inside the water-cooling pipe. The cold water can fully absorb heat during the residence stage, avoiding the waste of cold water discharged before completely absorbing heat due to continuous water supply. If the water-cooling pipe is too close to the overheated battery, the intermittent flow of cold water in the water-cooling pipe will automatically turn into continuous flow, so that the water-cooling pipe can absorb heat more efficiently.

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figures 1 to 13 The present invention provides a technical solution: a photovoltaic energy storage power station, comprising a power station box 1, a plurality of vertical racks 2 installed in the power station box 1, a plurality of batteries 4 arranged vertically on each vertical rack 2, and a water cooling mechanism 3 correspondingly arranged on one side of each vertical rack 2, the water cooling mechanism 3 controls the water cooling intensity by adjusting the spacing, and the water cooling mechanism 3 includes: A plurality of water cooling tubes 5 are arranged vertically, each water cooling tube 5 is distributed between two adjacent batteries 4, and the water cooling tube 5 is closer to the battery 4 that is accidentally overheated on one side to enhance water cooling, while applying unchanged water cooling to the battery 4 on the other side; A double-channel pipe 6 for supplying water to a row of water cooling pipes 5, the double-channel pipe 6 is vertically fixed at one side of the vertical rack 2, and the double-channel pipe 6 includes a square pipe and a double-channel baffle fixed in the square pipe; A row of water supply regulators 7 are installed on the dual-channel pipe 6, and each water supply regulator 7 corresponds to a water inlet port position arranged on the water cooling pipe 5; A sub-frame 8, one sub-frame 8 is fixed on each water-cooling tube 5, and the sub-frame 8 drives the water-cooling tube 5 by lifting; The integrated shaft 9 is used to drive a row of water supply regulators 7. The integrated shaft 9 is distributed in parallel on one side of the dual-channel pipe 6. The integrated shaft 9 is movably sleeved in a through hole opened on the external fixed protrusion of the dual-channel pipe 6, and the integrated shaft 9 is externally connected to a driving motor in the prior art. When the dual-channel pipe 6 transports cold water to the water-cooling pipe 5, the integrated shaft 9 continuously rotates to control the operation of the row of water supply regulators 7.

[0032] The plate-shaped energy storage battery 4 is provided with temperature sensors of the prior art to transmit the temperature of the two sides of the battery 4 to the main terminal of the power station in real time. Each sub-frame 8 is externally connected with a lifting drive mechanism of the prior art. The main terminal receives the temperature increase signal and controls the lifting drive mechanism of the temperature increase position to work, so as to independently control the lifting and lowering of the sub-frame 8 and change the spatial position of the sub-frame 8 between the two adjacent batteries 4 above and below. That is, if the temperature of a battery rises due to its own aging failure or battery charge and discharge overload and other unexpected reasons, it will be subjected to enhanced cooling treatment. The water-cooling pipe 5 between the two adjacent batteries 4 will automatically approach the battery 4 with rising temperature. The water-cooling pipe 5 close to the battery 4 can absorb heat more efficiently. At the same time, the cold water flow in the water-cooling pipe 5 will accelerate to flow, and a lower temperature area will be generated around the water-cooling pipe 5. The accelerated flow of the cold water will cause the water-cooling pipe 5 to cool down, and the other battery 4 far away from the water-cooling pipe 5 can also be effectively absorbed by the water-cooling pipe 5 that has been further cooled down. By effectively absorbing the heat dissipated by the overheated battery 4, the temperature of the battery 4 can be prevented from further increasing.

[0033] During normal water cooling, the water flow in the water cooling tube 5 is in an intermittent flow state, so that the temporarily stopped cold water can fully absorb the heat from the outside, which can more fully exchange heat than the traditional water cooling technology with continuous water flow, avoiding the energy waste caused by the cold water being discharged without sufficient heat absorption. However, when the battery overheats accidentally, the intermittent water flow mechanism in the water cooling tube 5 automatically ends and is converted into continuous water flow in the water cooling tube 5, so that the water cooling tube 5 can enhance heat absorption to give priority to solving the problem of accidental overheating of the battery 4.

The control seat 35 is fixed on the concave plate shell 10, and the plate 36 slides through the square hole opened on the control seat 35. The outer end of the spring 22 hooks the plate 36 by setting a hook plate. One end of the adjusting device 28 is fixed on the concave plate shell 10, and the fixed shaft 37 is movably sleeved in the through hole opened on the lever pressure frame 34. Two external protrusions are set on the plate 36 to limit its own movement range.

[0041] The water diversion gate 11 includes a door plate 41 blocking the water inlet port of the water-cooling pipe 5, an L-moving plate 39 fixed on one side of the door plate 41, and a direction plate frame 40 fixed on the concave plate shell 10. The direction plate frame 40 slides through the plate hole opened on the L-moving plate 39. One end of the lever pressure frame 34 is connected to a row of teeth on the L-moving plate 39 through an arc-shaped rack. A circular hole is opened at one end of the door plate 41 for water to flow into the water-cooling pipe 5.

[0042] The water booster gate 14 includes two half-sealing plates 45 symmetrically distributed to block the water inlet of the closing tube 17, a semi-movable shaft 43 distributed on one side of each semi-sealing plate 45, a main shaft 44 that is vertically driven by the two semi-movable shafts 43, and a half frame 42 for supporting the semi-movable shafts 43 and the main shaft 44. One end of the half frame 42 is fixed on the concave plate shell 10, and the half-sealing plate 45 slides through the plate hole opened on the half frame 42. One end of the semi-movable shaft 43 is meshed and connected to a row of teeth and grooves opened on the half-sealing plate 45 through a fixed gear. The other end of the semi-movable shaft 43 is meshed and connected to a ring-shaped bevel gear fixed on the main shaft 44 through a fixed bevel gear. One end of the main shaft 44 is meshed and connected to the cross plate rack 16 through a fixed shaft gear. The closing end of the closing tube 17 is opposite to the water inlet port of the water-cooling tube 5. The semi-movable shaft 43 and the main shaft 44 are respectively movably sleeved in two through holes opened on the half frame 42.

[0043] The rotating integrated shaft 9 drives the transfer shaft 19, and then the head shaft 26 drives the head gear 25 to rotate, and then the tail shaft 24 is driven by the overlapping gear 30. Next, the central shaft 23 rotates to drive the spring 22. The hook plate at the outer end of the spring 22 hooks the plate 36 encountered, and then the plate 36 moves to push the lever pressure frame 34. The lever pressure frame 34 swings to drive the L-moving plate 39 to move, and then the door panel 41 moves. Figure 8 The spring 22 in the middle continues to rotate counterclockwise, the spring 22 will deform and shrink, and the outer end of the spring 22 will remain in the state of hooking the plate 36 for a period of time. After the contraction pressure of the spring 22 is sufficient, the hook plate at the outer end of the spring 22 will deform, and then slide away from the end of the plate 36. Next, the return pressure spring 38 presses the lever pressure frame 34 to swing in the opposite direction to reset, and subsequent transmission causes the door panel 41 to reset and move. In summary, after the door panel 41 blocks the end of the water-cooling pipe 5 for a period of time, it will remain unblocked for a period of time, so that cold water is injected into the water-cooling pipe 5, and the cold water will stay in the water-cooling pipe 5 for a period of time. After the cold water fully absorbs heat, the remaining water is pushed away and replaced by the newly injected cold water.

[0044] In order to solve the problem of accidental overheating of the battery 4, the water cooling pipe 5 in the middle of the two batteries 4 will move, and the water cooling pipe 5 will drive the concave plate shell 10, Figure 7 Whether the concave plate shell 10 rises or falls, the contact point between the control member 12 and the concave frame 13 will change, that is, the concave frame 13 will force the T-disc wheel 33 to translate. Figure 8The T-disk wheel 33 in the middle drives the adjustment frame 32 to translate to the right, and then the overlapping shaft 29 drives the overlapping gear 30 to move along with it. If the overlapping gear 30 moves too much, it will be directly separated from the head gear 25, and the subsequent tail shaft 24 will no longer be transmitted. In this way, the drive of the mainspring 22 on the door control device 21 disappears, and the return pressure spring 38 presses the lever pressure frame 34 to reset. The subsequent transmission causes the door panel 41 to reset, and the circular hole on the door panel 41 will always remain connected with the water inlet port of the water cooling pipe 5, and cold water will be continuously supplied to the water cooling pipe 5. In summary, if the water cooling pipe 5 is too close to a battery 4, the intermittent water supply mode in the water cooling pipe 5 will be changed to a continuous water supply mode.

[0045] The two channels in the dual-channel tube 6 are respectively connected to different cold water supply mechanisms. The water-dividing channel supplies water to a row of water cooling tubes 5 normally, while the water-increasing channel is an additional water supply, and the intensity of the water supply depends on the heat absorption demand of the water cooling tube 5. That is, the closer the water cooling tube 5 is to an overheated battery 4, the greater the degree to which the T-disc wheel 33 that is accompanied by lifting is pressed by the concave frame 13. Figure 8 The greater the distance that the T-wheel 33 drives the adjusting frame 32 to move horizontally to the right, the Fig.11 The horizontal plate rack 16 in the middle moves the transmission main shaft 44 to the right, and then the semi-movable shaft 43 rotates to drive the semi-sealing plate 45 to move. The larger the distance between the two symmetrical semi-sealing plates 45, the stronger the cold water flow will be injected into the water-cooling pipe 5 nearby through the closing tube 17, and the water flow in the water-cooling pipe 5 will flow faster, thereby enhancing the cooling and heat absorption effect.
