Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power stations, and in particular to a safety detection device for an electrochemical energy storage power station. Background Art

[0002] An electrochemical energy storage power station is a power station that uses electrochemical batteries as energy storage elements and can store, convert, and release electrical energy. Electrochemical energy storage is a technology that converts electrical energy into chemical energy through an electrochemical reaction for storage and then converts the chemical energy back into electrical energy when needed. It utilizes the charge and discharge processes of batteries or similar chemical devices to achieve energy storage and release. For an electrochemical energy storage system, during charging, the negative electrode gains electrons and undergoes a reduction reaction; the positive electrode loses electrons and undergoes an oxidation reaction, and the discharge process is the opposite. Taking a lithium-ion battery as an example, during charging, the positive electrode (usually containing a lithium-containing compound) releases lithium ions and simultaneously releases electrons. The lithium ions move through the electrolyte towards the negative electrode (usually containing carbonaceous materials), and the electrons reach the negative electrode through an external circuit and recombine with the lithium ions to form a lithium compound. During the discharge process, the potential difference between the positive and negative electrodes causes electrons to flow from the negative electrode to the positive electrode, and the ions in the electrolyte also migrate accordingly, thereby releasing electrical energy. This electrochemical reaction is reversible, so the electrochemical energy storage device can be repeatedly charged and discharged.

[0003] An electrochemical energy storage power station is generally equipped with devices such as an energy storage system, a busbar cabin, a PCS step-up cabin, and a reactive power compensation prefabricated cabin. The energy storage system is composed of a dozen battery cores connected in series and parallel to form battery boxes. Multiple battery boxes are connected in series to form a battery string, and the battery strings are connected in parallel and integrated in a storage battery cabinet. Some of the storage battery cabinets are arranged outdoors. Since the battery boxes generate high temperatures during operation, temperature detection is required, and cooling measures are taken to ensure the safety of the storage battery cabinet. Some existing storage battery cabinets use fans to cool the inside, but the cooling effect is not ideal, the cooling is not uniform, and although a dust-proof net is set at the inlet of the fan to prevent dust from entering the cabinet, some fine dust can pass through the dust-proof net and enter the inside of the storage cabinet. The fine dust covering the surface of the battery box will hinder the heat dissipation, resulting in an increase in the internal temperature of the battery box. A long-term high-temperature environment may accelerate the aging process of the battery, shorten the service life of the battery, and even cause safety problems. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0045] As Figures 1 to 12 shown, the safety detection device of the electrochemical energy storage power station according to the embodiment of the present invention includes a cabinet body 1 and a plurality of battery box bodies 4, wherein two sides of the front surface of the cabinet body 1 are hinged with cabinet doors 2. The device further includes a partition frame 3, a refrigeration device, an infusion circulation mechanism 17, a transmission mechanism 18, and a blowing mechanism 19.

[0046] Among them, the partition rack 3 is arranged inside the cabinet body 1. The partition rack 3 includes a plurality of compartments. A first heat conducting plate 8 and a second heat conducting plate 9 are respectively arranged corresponding to the bottom and the top of each compartment. A temperature sensor 5 and a smoke sensor 6 are respectively arranged inside each compartment. Each battery box body 4 is correspondingly arranged inside each compartment. The temperature sensor 5 is used to monitor the temperature of the battery box body 4, while the smoke sensor 6 is used for smoke detection to realize fire warning.

[0047] Among them, the refrigeration device includes a liquid storage tank 10 arranged at the top of the partition rack 3, an isolation box 11 arranged at the top of the liquid storage tank 10, and an air outlet hood 12 arranged at the top of the isolation box 11. The liquid storage tank 10 is filled with a coolant. A horizontal partition plate 13 is arranged inside the isolation box 11. A plurality of semiconductor refrigeration chips 16 are fixedly arranged on the partition plate 13. The heating surface of the semiconductor refrigeration chip 16 is connected with a heat conducting column 15, and the cooling surface of the semiconductor refrigeration chip 16 is connected with a cold conducting column 14. The upper end of the heat conducting column 15 penetrates into the inside of the air outlet hood 12, and the lower end of the cold conducting column 14 penetrates into the inside of the liquid storage tank 10. The heating surface of the semiconductor refrigeration chip 16 faces upward so as to transfer heat to the heat conducting column 15, and the cooling surface of the semiconductor refrigeration chip 16 faces downward so as to transfer cold to the cold conducting column 14. The semiconductor refrigeration chip 16 is used to cool down the coolant in the liquid storage tank 10.

[0048] Among them, the liquid infusion circulation mechanism 17 is used to circulate and convey the coolant in the liquid storage tank 10 to the first heat conducting plate 8 and the second heat conducting plate 9, so as to cool down and dissipate heat from the battery box body 4. The transmission mechanism 18 is used to drive the air blowing mechanism 19 to operate by using the power of the flowing coolant, and the air blowing mechanism 19 is used to blow and cool the heat conducting column 15 inside the air outlet hood 12, so as to cool down the semiconductor refrigeration chip 16.

[0049] When working, the temperature sensor 5 monitors the temperature of the battery box body 4 and uploads it to the power monitoring system. At the same time, the smoke sensor 6 monitors whether there is smoke generated in the battery box body 4 and also uploads the monitoring result to the power monitoring system to achieve fire warning. Meanwhile, the semiconductor refrigeration sheet 16 and the infusion circulation mechanism 17 are turned on to work. The heat generated by the semiconductor refrigeration sheet 16 is transferred to the heat conduction column 15, causing the temperature of the heat conduction column 15 to rise. The cold generated by the semiconductor refrigeration sheet 16 is transferred to the cold conduction column 14, making the cold conduction column 14 in a low-temperature state. Then, the cold conduction column 14 transfers the cold to the coolant inside the liquid storage tank 10, making the coolant in a low-temperature state. Then, through the infusion circulation mechanism 17, the low-temperature coolant can enter the first heat conduction plate 8 and the second heat conduction plate 9 at the bottom and top of the battery box body 4 respectively, and the coolant absorbs heat to cool the battery box body 4, thereby realizing the synchronous cooling of the upper and lower parts of the battery box body 4, and the cooling effect is uniform. During the circulation process of the coolant, it can drive the blowing mechanism 19 to operate, thereby purging and cooling the heat conduction column 15 inside the air outlet hood 12 to ensure that the semiconductor refrigeration sheet 16 can work efficiently.

[0050] Thus, the safety detection device of the electrochemical energy storage power station in the embodiment of the present invention can not only use the flow of the coolant to synchronously cool and dissipate heat on the upper and lower surfaces of the battery box body 4, but also use the power generated by the flow of the coolant to allow external air to enter the air outlet hood 12 to cool the core components of the cooling, without using additional power, saving the energy consumption of the device to a certain extent, and avoiding direct contact between the external air and the battery box body 4 inside the cabinet 1, and preventing fine dust from entering the cabinet 1.

[0051] Specifically, two bases 7 are respectively installed at the bottom of each compartment. The first heat conduction plate 8 is located between the two bases 7, and the battery box body 4 is installed on the two bases 7. The base 7 is used to support the battery box body 4 to prevent the battery box body 4 from crushing the first heat conduction plate 8.

[0052] Specifically, the first heat conduction plate 8 can be attached to the bottom of the battery box body 4, and at the same time, the second heat conduction plate 9 can be attached to the surface of the top of the battery box body 4.

[0053] Among them, the materials of the first heat conduction plate 8 and the second heat conduction plate 9 are both heat-conducting plastics. Heat-conducting plastics are plastic composites formed by adding heat-conductive metal oxides, graphite fibers or carbon fibers, etc. to ordinary plastics. This new material of heat-conducting plastics has begun to be widely used in the market. Its high heat conductivity can replace some radiators, shells, etc. made of aluminum. The interiors of the first heat conduction plate 8 and the second heat conduction plate 9 are both hollow designs, and the top of the first heat conduction plate 8 is flush with the top of the base 7.

[0054] Specifically, the heat-conducting columns 15 and the heat-dissipating columns 14 are both made of copper material, and the multiple heat-conducting columns 15 and the multiple heat-dissipating columns 14 are arranged in an interleaved manner.

[0055] Specifically, a liquid filling port needs to be opened at the top of the liquid storage tank 10 for adding coolant to the inside. Before working, a sufficient amount of heat-conducting oil needs to be poured into the inside of the liquid storage tank 10 as the coolant.

[0056] Specifically, the surface on one side of the air outlet hood 12 is designed to be open and penetrates through to the outer surface of the cabinet body 1. The outlet of the air outlet hood 12 is correspondingly installed at the air outlet on the side wall of the cabinet body 1, and a second dust-proof net 21 is installed at the outlet of the air outlet hood 12 to prevent dust from entering.

[0057] In some embodiments of the present invention, the infusion circulation mechanism 17 includes a pump body 171, a delivery pipe 172, a box body 173, a first long pipe 174, and a second long pipe 175. The pump body 171 is arranged on the top of the partition frame 3, the box body 173 is arranged on one side of the partition frame 3, the inlet end of the pump body 171 is communicated with the liquid storage tank 10 through a connecting pipe, the outlet end of the pump body 171 is communicated with one end of the delivery pipe 172, the other end of the delivery pipe 172 is communicated with the box body 173, the side of the box body 173 away from the delivery pipe 172 is communicated with the first long pipe 174, one side of the first heat-conducting plate 8 and the second heat-conducting plate 9 are respectively communicated with the first long pipe 174 through a hose, the other side of the first heat-conducting plate 8 and the second heat-conducting plate 9 are respectively communicated with the second long pipe 175 through a hose, and the second long pipe 175 is communicated with the liquid storage tank 10.

[0058] During operation, the pump body 171 is started to make the coolant in the liquid storage tank 10 pass through the delivery pipe 172, the box body 173, and the first long pipe 174, and then enter the inside of the first heat-conducting plate 8 and the second heat-conducting plate 9 respectively through multiple hoses. The heat generated during the operation of the battery box body 4 is respectively transferred to the first heat-conducting plate 8 and the second heat-conducting plate 9, and transferred to the coolant flowing inside the first heat-conducting plate 8 and the second heat-conducting plate 9. After the coolant in the first heat-conducting plate 8 and the second heat-conducting plate 9 absorbs heat, it then enters the inside of the second long pipe 175 through the hose on the other side, and then returns to the inside of the liquid storage tank 10 through the second long pipe 175, realizing cycle refrigeration. Moreover, the first heat-conducting plate 8 and the second heat-conducting plate 9 can cool the battery box body 4 synchronously from the upper and lower sides, making the temperature reduction more uniform and the temperature reduction effect better.

[0059] In some embodiments of the present invention, the transmission mechanism 18 includes a connecting block 181 and a turntable 183 disposed within the box body 173, as well as a vertical column 185 and a first bevel gear set disposed within the box body 173. The turntable 183 is rotatably connected to the inner wall of the box body 173, and a plurality of blades 182 arranged in a ring are fixedly provided on the outer peripheral surface of the turntable 183. A transmission column 184 is fixedly connected to the center of one side of the turntable 183. The transmission column 184 passes through the side wall of the box body 173 and is rotatably matched with the side wall of the box body 173. The top end of the vertical column 185 is drivingly connected to the transmission column 184 through the first bevel gear set. That is, when the coolant flows through the box body 173, it can drive the turntable 183 and the transmission column 184 to rotate synchronously, and then transmit the power to the vertical column 185 through the first bevel gear set to drive the vertical column 185 to rotate.

[0060] Wherein, the first bevel gear set includes a first bevel gear 186 fixedly provided at the end of the transmission column 184 and a second bevel gear 187 fixedly provided at the top end of the vertical column 185, and the first bevel gear 186 is meshed and connected with the second bevel gear 187.

[0061] Wherein, there are two connecting blocks 181, and the two connecting blocks 181 are symmetrically installed on the left and right sides within the box body 173. Each connecting block 181 is arc-shaped near the middle side to facilitate the coolant flowing through the box body 173 to drive the turntable 183 to rotate.

[0062] Wherein, a plurality of first bearing seats are installed on the inner side wall of the cabinet body 1 corresponding to the extending direction of the vertical column 185, and the vertical column 185 is rotatably connected to each first bearing seat through a first bearing, thereby realizing the support and installation of the vertical column 185.

[0063] In some embodiments of the present invention, the blowing mechanism 19 includes a transverse cylinder 191, a connecting seat 192, a rotating column 193, an air supply pipe 195, and a second bevel gear set. The transverse cylinder 191 is disposed at the lower inner part of the cabinet body 1. One end of the air supply pipe 195 is communicated with the air outlet hood 12, and the other end of the air supply pipe 195 is communicated with the transverse cylinder 191, and the axial direction of the transverse cylinder 191 is perpendicular to the axial direction of the vertical column 185. The connecting seat 192 is installed inside the transverse cylinder 191, and the rotating column 193 is rotatably connected to the connecting seat 192. A plurality of fan blades 194 are annularly provided at one end of the rotating column 193. The lower end of the vertical column 185 rotatably penetrates through the transverse cylinder 191 and extends into the inside of the transverse cylinder 191, and the other end of the rotating column 193 is drivingly connected to the lower end of the vertical column 185 through the second bevel gear set.

[0064] Wherein, the inlet of the transverse cylinder 191 is correspondingly installed at the air inlet on the side wall of the cabinet body 1, and a first dust-proof net 20 is installed at the inlet of the transverse cylinder 191 to prevent dust from entering the transverse cylinder 191.

[0065] Among them, the second bevel gear set includes a third bevel gear 196 fixedly arranged at the other end of the rotating column 193 and a fourth bevel gear 197 fixedly arranged at the lower end of the vertical column 185, and the third bevel gear 196 is meshed and connected with the fourth bevel gear 197.

[0066] During operation, when the coolant flows through the interior of the box body 173, it can push the blade 182 to drive the turntable 183 to rotate. Then the turntable 183 drives the transmission column 184 to rotate, so that the transmission column 184 drives the vertical column 185 to rotate through the first bevel gear set. The vertical column 185 then drives the rotating column 193 to rotate through the second bevel gear set. The rotating column 193 drives the fan blade 194 on its surface to rotate. The rotation of the fan blade 194 enables the external air to enter the interior of the transverse cylinder 191 through the first dust-proof net 20, and then send air to the interior of the air outlet hood 12 through the air delivery pipe 195. The conveyed air blows towards the surface of the heat conduction column 15. The heat on the surface of the heat conduction column 15 exchanges heat with the flowing air, thereby cooling the heat conduction column 15, reducing the temperature of the heat conduction column 15, preventing the semiconductor refrigeration sheet 16 from being damaged due to continuous heat generation without being cooled, and maintaining the efficient operation of the semiconductor refrigeration sheet 16. Moreover, when using the flow of the coolant to drive the rotation of the fan blade 194, there is no need to adopt additional electric drive, which saves the energy consumption of the device to a certain extent. At the same time, the external air is only discharged after passing through the transverse cylinder 191, the air delivery pipe 195 and the air outlet hood 12, and does not enter the interior of the cabinet body 1, and also prevents fine dust from entering the interior of the cabinet body 1 and covering the surface of the battery box body 4.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
