Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation and energy storage, and in particular to an intelligent charger battery module based on photovoltaic components. Background Art

[0002] As a typical renewable energy source, the power generation of solar energy is greatly affected by weather and time, and is intermittent and unstable. The photovoltaic energy storage system can store electricity when there is sufficient sunshine and release electricity when there is insufficient sunshine or at night, which effectively smoothes the fluctuation of photovoltaic power generation and improves the continuity and stability of energy supply. At present, some photovoltaic power generation uses storage cabinets for energy storage. The storage cabinet is mainly composed of cabinet structure, battery module, control and protection system, and auxiliary equipment. In order to increase the storage capacity of the storage cabinet, the designer will place multiple batteries in the storage cabinet. The control and protection system is used to control the charging and discharging process of the storage cabinet and protect the battery from overcharging, over-discharging, short circuit and other damage.

[0003] In order to ensure the safe use of the battery cabinet, the staff needs to regularly inspect and maintain the battery cabinet. After long-term service, the battery may have leakage. If the staff fails to discover it in time, there are certain work hazards during maintenance. In addition, the battery may have high temperature during charging. Some battery cabinets cannot remove the connecting wires between the battery and other components in time, resulting in continuous temperature increase and even fire accidents. The flames may spread to other components through the connecting wires, causing greater losses. Summary of the invention

[0004] In response to the above problems, the present application provides an intelligent charger battery module based on photovoltaic components to solve the problem that after long-term service in the prior art, the battery may have leakage. If the staff fails to discover it in time, there are certain work hazards during maintenance. In addition, the battery may have high temperature during charging. Some power cabinets cannot remove the connecting wires between the battery and other components in time, resulting in continuous temperature increase and even fire accidents. The flames may spread to other components through the connecting wires, causing the losses to increase.

[0005] The technical solution of the present invention is:

[0006] A smart charger battery module based on a photovoltaic module comprises a cabinet, a control and protection mechanism and a battery module are installed inside the cabinet, the battery module comprises a battery for storing electric energy, the battery is connected to the control and protection mechanism through an integrated connector, two expansion tubes are symmetrically fixedly installed at the end of the battery module, and the gas inside the expansion tube absorbs heat and expands, pushing the integrated connector to separate from the battery;

[0007] The cabinet body is equipped with a door opening self-inspection mechanism, which includes an insulating handle and a pressing column. When the cabinet door is opened, the pressing column needs to be pressed to drive multiple leakage detection units to fit and detect the battery. When the green warning light is on, subsequent maintenance work can be carried out.

[0008] An emergency door opening mechanism is installed on the inside of the cabinet door. The emergency door opening mechanism includes an extrusion column. When the integrated connector moves, the transmission drives the extrusion column to move in the opposite direction, thereby driving the plunger to move downward to release the lock with the cabinet body.

[0009] Furthermore, the integrated connector is plugged into the end of the battery, the battery is fixedly installed inside the cabinet, a force-bearing plate is installed inside the expansion tube, a soft sealing ring is fixedly installed outside the force-bearing plate, and the outside of the soft sealing ring is sealed and fitted with the inside of the expansion tube;

[0010] A baffle and a limit frame are fixedly installed on the inner side of the expansion tube, a pressure sensor is inlaid and fixedly installed on the inner side of the baffle, a top column is fixedly installed on the end of the force plate, and the top column is slidably plugged with the limit frame.

[0011] Furthermore, the cabinet door is hinged to the cabinet body, the handle is fixedly installed on the outside of the cabinet door, the pressing column slides through the cabinet door and the handle, a linkage plate is fixedly installed on the end of the pressing column, a first spring is fixedly installed between the linkage plate and the inside of the cabinet door, and the first spring is movably sleeved on the outer periphery of the pressing column;

[0012] A linkage rod is fixedly installed on the outer side of the linkage plate, and one end of the linkage rod away from the linkage plate is fixedly connected to the leakage detection unit.

[0013] Furthermore, a limit block is fixedly installed on the outer side of the cabinet door, a through slot is provided inside the limit block, and the linkage rod is slidably installed in the through slot.

[0014] Furthermore, the plunger is slidably mounted on the top of the cabinet door, the plunger is plugged into the cabinet body, a second spring is fixedly mounted between the bottom of the plunger and the inner side of the cabinet door, and a linkage rope is fixedly connected between the bottom of the plunger and the outer side of the pressing column.

[0015] Furthermore, the warning light is fixedly installed on the outside of the cabinet door, and the leakage detection unit is electrically connected to the warning light.

[0016] Furthermore, a plurality of magnets are embedded and fixedly installed on the inner side of the cabinet door, and a connected air chamber and a connecting hole are opened on the inner side of the cabinet door. An extrusion plate is slidably installed inside the air chamber, and a plurality of third springs are fixedly installed between the extrusion plate and the air chamber.

[0017] Furthermore, an extrusion tube is fixedly installed on the outer side of the cabinet door, the extrusion tube is connected with the connecting hole, and the extrusion column is slidably installed inside the extrusion tube.

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) In the case of an intelligent charger battery module based on a photovoltaic module described in the present invention, when the battery is abnormally charged or discharged, the battery may heat up, the air in the expansion tube expands due to the heat, squeezing the top column and the force plate to move toward the cabinet door, and the soft sealing ring deforms and squeezes the pressure sensor. If the pressure on the pressure sensor is small, the heat dissipation device in the cabinet can be linked to accelerate the heat dissipation, so that the battery temperature is lower than the set safe working temperature;

[0020] If the battery temperature continues to rise, the pressure on the pressure sensor increases. The pressure sensor controls the cabinet to cut off power through the data processor to reduce the risk of battery fire. The top column hits the integrated connector, causing the integrated connector to detach from the battery, disconnecting the battery with abnormal temperature from other components to prevent damage to other components and reduce losses. If the battery catches fire later, it can also reduce the spread of the fire and reduce losses.

[0021] The integrated connector moves to drive the leakage detection unit to fit the battery to detect whether the battery is leaking. Other detection mechanisms can also be added. Before the staff arrives at the site, the processor in the cabinet can analyze the cause of abnormal battery temperature based on the data fed back by the detection mechanism and formulate a reference solution to facilitate the staff to quickly solve the problem;

[0022] At the same time, the plunger moves down to release the lock on the cabinet body. The staff can use external tools to pull the cabinet door from a distance, and then check the internal situation of the cabinet. When it is confirmed that close-up operations are possible, subsequent operations can be carried out to improve work safety.

[0023] (2) The intelligent charger battery module based on photovoltaic components described in the present invention, during daily maintenance, when the staff opens the cabinet door, the leakage detection unit is attached to the battery to detect whether the battery is leaking. Other detection mechanisms can also be added here to detect other items of the battery, thereby ensuring the safety of subsequent staff during maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0043] As shown in Figure 1- Fig.11 As shown, an embodiment of the present invention provides a smart charger battery module based on a photovoltaic assembly, including a cabinet 1, a control and protection mechanism 2 and a battery module 3 are installed inside the cabinet 1, and the battery module 3 includes a battery 31 for storing electric energy, and the battery 31 is connected to the control and protection mechanism 2 through an integrated connector 32. Two expansion tubes 33 are symmetrically fixedly installed at the end of the battery module 3. The gas inside the expansion tube 33 absorbs heat and expands, pushing the integrated connector 32 to separate from the battery 31, quickly disconnecting the abnormal battery 31 from other components, preventing damage to other components, and reducing losses;

[0044] A door opening self-inspection mechanism 4 is installed on the outside of the cabinet body 1. The door opening self-inspection mechanism 4 includes a handle 42 and a pressing column 43 made of insulating material. When opening the cabinet door 41, it is necessary to press the pressing column 43 to drive multiple leakage detection units 411 to fit and detect the battery 31. When the green warning light 412 lights up, subsequent maintenance work can be carried out to improve operation safety. The warning light 412 is fixedly installed on the outside of the cabinet door 41, and the leakage detection unit 411 is electrically connected to the warning light 412.

[0045] In this embodiment, during daily maintenance, the staff uses the thumb to press the pressing column 43, driving the leakage detection unit 411 to fit the battery 31 to detect whether the battery 31 is leaking. Other detection mechanisms can also be added here to detect other items of the battery, thereby ensuring the safety of subsequent staff during maintenance. The specific detection mechanisms are all related to the existing technology and will not be repeated in this article. The leakage detection unit 411 sends the detection result to the data processor, and then controls the lighting state of the warning light 412. The green light is safe and the red light is a fault. It is necessary to turn off the power before working to ensure safe operation.

[0046] Specifically, an emergency door opening mechanism 5 is installed on the inner side of the cabinet door 41, and the emergency door opening mechanism 5 includes an extrusion column 57. When the integrated connecting head 32 moves, the transmission drives the extrusion column 57 to move in the opposite direction, thereby driving the plunger 47 to move downward to release the lock with the cabinet body 1. The staff can use external tools to pull the cabinet door 41 at a long distance, and then check the internal situation of the cabinet body 1. When it is confirmed that close-range operation is possible, subsequent operations can be carried out to improve work safety.

[0047] Specifically, a plurality of magnets 51 are embedded and fixedly installed on the inner side of the cabinet door 41, which are used to absorb and fix the integrated connector 32 detached from the battery 31. A connected air chamber 54 and a connecting hole 55 are opened on the inner side of the cabinet door 41. An extrusion plate 52 is slidably installed inside the air chamber 54. A plurality of third springs 53 are fixedly installed between the extrusion plate 52 and the air chamber 54, which are used for resetting the extrusion plate 52. An extrusion tube 56 is fixedly installed on the outer side of the cabinet door 41. The extrusion tube 56 is connected to the connecting hole 55, and an extrusion column 57 is slidably installed inside the extrusion tube 56.

[0048] In this embodiment, the integrated connector 32 hits the extrusion plate 52, and the extrusion plate 52 squeezes the air in the air chamber 54 and the connecting hole 55, thereby driving the extrusion column 57 to squeeze the leakage detection unit 411 to fit the battery 31, and detect whether the battery 31 is leaking. Other detection mechanisms can also be added. Before the staff arrives at the site, the processor in the cabinet 1 can analyze the cause of the abnormal temperature of the battery 31 based on the data fed back by the detection mechanism, and formulate a reference solution to facilitate the staff to quickly solve the problem;

[0049] At the same time, the plunger 47 moves downward to release the lock with the cabinet body 1. The staff can use external tools to pull the cabinet door 41 from a distance, and then check the internal situation of the cabinet body 1. When it is confirmed that close-up operations are possible, subsequent operations can be carried out to improve work safety.

[0050] Specifically, the integrated connector 32 is plugged into the end of the battery 31, the battery 31 is fixedly installed inside the cabinet 1, a force-bearing plate 38 is installed inside the expansion tube 33, a soft sealing ring 39 is fixedly installed outside the force-bearing plate 38, and the outside of the soft sealing ring 39 is sealed and fitted with the inside of the expansion tube 33;

[0051] A baffle 34 and a limit frame 36 are fixedly installed on the inside of the expansion tube 33, a pressure sensor 35 is embedded and fixedly installed on the inside of the baffle 34, a top column 37 is fixedly installed on the end of the force plate 38, the top column 37 is slidably plugged into the limit frame 36, and the limit frame 36 is used to limit the movement trajectory of the top column 37.

[0052] In this embodiment, when the battery is abnormally charged or discharged, the temperature of the battery 31 may rise, the air in the expansion tube 33 expands due to the heat, and the top column 37 and the force plate 38 move toward the cabinet door 41, and the soft sealing ring 39 deforms and squeezes the pressure sensor 35. If the pressure on the pressure sensor 35 is small, the soft sealing ring 39 does not cross the baffle 34, and the heat dissipation device in the cabinet 1 can be linked to accelerate the heat dissipation, so that the temperature of the battery 31 is lower than the set safe working temperature;

[0053] If the temperature of the battery 31 continues to rise, the pressure on the pressure sensor 35 increases, and the pressure sensor 35 controls the cabinet 1 to cut off the power through the data processor, thereby reducing the risk of battery fire. The soft sealing ring 39 passes over the baffle 34, and the top column 37 hits the integrated connector 32, so that the integrated connector 32 is separated from the battery 31 and adsorbed on the outside of the magnet 51, thereby disconnecting the battery 31 with abnormal temperature from other components, preventing damage to other components and reducing losses. If the battery 31 catches fire subsequently, it can also reduce the spread of the fire to a certain extent, thereby reducing losses.

[0054] Specifically, the cabinet door 41 is hinged to the cabinet body 1, and the handle 42 is fixedly installed on the outside of the cabinet door 41, so that the staff can pull and open the cabinet door 41 conveniently. The pressing column 43 slides through the cabinet door 41 and the handle 42, and a linkage plate 44 is fixedly installed on the end of the pressing column 43. A first spring 45 is fixedly installed between the linkage plate 44 and the inner side of the cabinet door 41 for resetting the linkage plate 44. The first spring 45 is movably sleeved on the outer periphery of the pressing column 43.

[0055] A linkage rod 49 is fixedly installed on the outer side of the linkage plate 44 , and one end of the linkage rod 49 away from the linkage plate 44 is fixedly connected to the leakage detection unit 411 .

[0056] Specifically, a limit block 410 is fixedly installed on the outer side of the cabinet door 41, a through groove is opened inside the limit block 410, and the linkage rod 49 is slidably installed in the through groove. The limit block 410 is used to limit the moving trajectory of the linkage rod 49, so that the movement of the linkage rod 49 is more stable.

[0057] Specifically, the plunger 47 is slidably installed on the top of the cabinet door 41, the plunger 47 is plugged into the cabinet body 1, a second spring 48 is fixedly installed between the bottom of the plunger 47 and the inner side of the cabinet door 41 for resetting the plunger 47, and a linkage rope 46 is fixedly connected between the bottom of the plunger 47 and the outer side of the pressing column 43.

[0058] In this embodiment, the staff uses the thumb to press the pressing column 43, driving the linkage plate 44 and the linkage rod 49 to move toward the battery 31. The pressing column 43 drives the plunger 47 to move downward through the linkage rope 46, releasing the lock between the plunger 47 and the cabinet body 1. The staff then rotates and uses the remaining four fingers to pull the cabinet door 41 to rotate the cabinet door 41 to open it.

[0059] How it works:

[0060] During routine maintenance, the staff uses the thumb to press the pressing column 43, driving the linkage plate 44 and the linkage rod 49 to move toward the battery 31. The linkage rod 49 drives the leakage detection unit 411 to fit the battery 31 to detect whether the battery 31 is leaking. Other detection mechanisms can also be added here to detect other items of the battery, thereby ensuring the safety of subsequent staff during maintenance. The specific detection mechanisms belong to the prior art and will not be described in detail herein. The leakage detection unit 411 sends the detection result to the data processor, and then controls the light state of the warning light 412. The green light is safe, and the red light is a fault. It is necessary to cut off the power before working, so as to ensure safe operation.

[0061] The pressing column 43 drives the plunger 47 to move downward through the linkage rope 46 to release the lock between the plunger 47 and the cabinet body 1. The staff then rotates and uses the remaining four fingers to pull the cabinet door 41 to rotate the cabinet door 41 to open it.

[0062] When the battery is abnormally charged or discharged, the temperature of the battery 31 may rise, and the air in the expansion tube 33 expands due to the heat, squeezing the top column 37 and the force plate 38 to move toward the cabinet door 41, and the soft sealing ring 39 deforms and squeezes the pressure sensor 35. If the pressure on the pressure sensor 35 is small, the soft sealing ring 39 does not cross the baffle 34, and the heat dissipation device in the cabinet 1 can be linked to accelerate the heat dissipation, so that the temperature of the battery 31 is lower than the set safe working temperature;

[0063] If the temperature of the battery 31 continues to rise, the pressure on the pressure sensor 35 increases, and the pressure sensor 35 controls the cabinet 1 to cut off the power through the data processor, thereby reducing the risk of battery fire. The soft sealing ring 39 passes over the baffle 34, and the top column 37 hits the integrated connector 32, so that the integrated connector 32 is separated from the battery 31 and adsorbed on the outside of the magnet 51, thereby disconnecting the battery 31 with abnormal temperature from other components, preventing damage to other components and reducing losses. If the battery 31 catches fire later, the spread of the fire can be reduced, which can also play a role in reducing losses.

[0064] The integrated connector 32 hits the extrusion plate 52, and the extrusion plate 52 squeezes the air in the air chamber 54 and the connecting hole 55, thereby driving the extrusion column 57 to squeeze the linkage rod 49, so that the linkage rod 49 and the leakage detection unit 411 fit the battery 31 to detect whether the battery 31 is leaking. Other detection mechanisms can also be added. Before the staff arrives at the site, the processor in the cabinet 1 can analyze the cause of the abnormal temperature of the battery 31 based on the data fed back by the detection mechanism, and formulate a reference solution to facilitate the staff to quickly solve the problem;

[0065] At the same time, the plunger 47 moves downward to release the lock with the cabinet 1. The specific work process will not be repeated here. The staff can use external tools to pull the cabinet door 41 from a distance, and then check the internal situation of the cabinet 1. When it is confirmed that close-range operation is possible, subsequent operations can be carried out to improve work safety.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
