Description

Technical Field

[0001] The invention relates to the technical field of battery monitoring, and in particular to an online monitoring device for batteries in a transformer substation. Background Art

[0002] Monitor the temperature changes of battery packs and single cells. Abnormal temperature may indicate battery problems. Through the above technologies and systems, substation batteries can be effectively monitored and managed online, improving the reliability, safety and service life of the battery system, ensuring the stable operation and emergency response capabilities of the power system.

[0003] The patent with the announcement number CN219086049U discloses an online monitoring device for the temperature of a single battery in a substation, including a monitoring module and a loading and unloading module. The monitoring module includes a monitoring chamber connected to the monitoring module, a mobile power supply connected to the bottom of the inner chamber of the monitoring chamber, a partition connected between the monitoring chamber and the mobile power supply, and a battery attached to the top of the partition. In the patent, the controller shrinks the movable end of the electric push rod, and then the toothed plate drives the two gears to rotate. The gears loosen the clamping bolts through the swing plate, the rod body, and the wrench. After the clamping bolts are separated from the partition, the insulation plate is opened, and then the battery is attached to the top of the partition, the mobile power supply is connected to the battery, and then the movable end of the electric push rod is controlled to extend, the clamping bolts are tightened, and the wiring is compressed. Then the temperature sensor and the humidity sensor monitor the mobile power supply in real time, avoiding manual tightening of the clamping bolts, and improving the monitoring efficiency. However, the patent still has the problem of not being able to monitor the discharge of the battery during use, which leads to internal overheating and easy spontaneous combustion. Therefore, it is very necessary to design an online monitoring device for substation batteries. Summary of the invention

[0004] The object of the present invention is to provide an online monitoring device for storage batteries in a substation to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an online monitoring device for a substation battery, comprising a battery body, a ventilation port is provided on the top surface of the battery body, a terminal is fixedly connected to the front top surface of the battery body, a power module is installed inside the battery body, a monitoring and protection mechanism is installed above the power module, a monitoring component is provided above the monitoring and protection mechanism, a safety protection mechanism is provided above the monitoring component, and a heat dissipation mechanism is provided on the top of the safety protection mechanism;

[0006] The monitoring component includes an integrated module, which is fixedly connected to the top of the power module, and the rear side of the integrated module is electrically connected to a transmission wire, and the end of the transmission wire away from the integrated module is fixedly connected to a temperature sensor, and the outer side of the temperature sensor is fixedly connected to a heat collecting copper sheet, and the outer side of the heat collecting copper sheet is fixedly connected to a heat spreading plate, and the left end of the heat collecting copper sheet is fixedly connected to a collecting guide sheet. When the heat spreading plate absorbs heat from the side of the battery and transfers the heat to the heat collecting copper sheet, the temperature sensor on the heat collecting copper sheet transmits the induced heat to the integrated module through the transmission wire, and sends the detected data to an external terminal through the built-in wireless module of the integrated module, and the data is viewed by the terminal to realize online real-time monitoring of the battery temperature of the battery body.

[0007] The monitoring and protection mechanism includes a protective end shell, which is fixedly connected to the front side of the integrated module, a guide bar is fixedly connected to the inner wall of the protective end shell, an inner alloy wire is arranged on the outer side of the guide bar, a sliding plate is slidably connected to the outer side of the guide bar, a connecting rod is fixedly connected to the front edge of the sliding plate, an end of the connecting rod away from the sliding plate is fixedly connected to a wiring block, two power-carrying contacts and two contact connecting pieces are arranged on the bottom surface of the wiring block, a transformer is fixedly connected to the left end of the power-carrying contact piece, an output wire is fixedly connected to the top of the transformer, the power module is composed of multiple batteries, and a heat spreader is attached between the two batteries, two ends of the inner alloy wire are fixedly connected to the protective end shell and the sliding plate respectively, the output wire is electrically connected to the terminal post, the contact connecting piece is electrically connected to the power module through a wire, and the collecting guide is away from the heat collecting copper One end of the sheet is fixedly connected to a protective end shell, and part of the heat on the heat-collecting copper sheet is transferred to the protective end shell through the collecting guide sheet. The temperature rise of the protective end shell will cause the temperature of the inner alloy wire to rise. Since the inner alloy wire is made of nickel-titanium alloy, it begins to shrink after the temperature rises. At this time, the heated inner alloy wire will pull the sliding plate to slide along the guide bar. When the sliding plate slides, it will drive the connected connecting rod to move together, so that the connecting rod pulls the wiring block. When the temperature inside the protective end shell is high, the contraction distance of the inner alloy wire increases. The contraction of the inner alloy wire will pull the wiring block away from the contact link through the connecting rod, so that the wiring block no longer contacts the contact link. At this time, the contact link and the energized contact piece are in a short-circuit state. At this time, the power module cannot transmit electrical energy to the energized contact piece through the contact link connected by the wire. By disconnecting the energized line, the power module is prevented from continuing to supply power and causing the temperature to continue to rise.

[0008] The heat dissipation mechanism comprises a linkage rod, which is fixedly connected to the right side of the connecting rod, a baffle is fixedly connected to the top of the linkage rod, a cooling fan is arranged below the baffle, a fixing plate is fixedly connected to the bottom surface of the cooling fan, a filter is fixedly connected to the inside of the ventilation port, a pressure block slide is fixedly connected to the right side of the ventilation port, a voltage block is slidably penetrated by the top surface of the pressure block slide, an electric connection block is fixedly connected to the right side of the cooling fan, the fixing plate is fixedly connected to the top surface of the inside of the battery body, the baffle is slidably connected to the ventilation port, the right end of the baffle is an inclined section, the electric connection block is electrically connected to the cooling fan, a spring sheet is fixedly connected to the top surface of the pressure block slide, and two ends of the spring sheet are respectively connected to the pressure block slide and the voltage block. The pressure block is fixedly connected. When the connecting rod moves, the connecting rod will drive the connected connecting rod to pull the baffle and the ventilation port to slide, so that the baffle and the filter in the ventilation port move relative to each other. At this time, the baffle moves and contacts and rubs with the filter, so that the filter shakes off the dust through the vibration generated by the friction, thereby preventing the dust attached to the filter from affecting the ventilation. At the same time, after the baffle moves, it will no longer block the bottom of the ventilation port, and the inclined cross-section of the baffle will no longer block the voltage block, so that the voltage block moves downward along the pressure block slide under the action of the spring sheet, close to the power block connected to the cooling fan. At this time, the power block and the voltage block contact each other, so that the cooling fan is in a powered-on state, and the power module is used to supply power to make the cooling fan in a working state, so that the cooling fan can quickly discharge the heat accumulated in the battery body through the ventilation port.

[0009] According to the above technical solution, the safety protection mechanism includes a safety plug rod, which is fixedly connected to the right side of the connecting rod, and the safety plug rod is located at the rear side of the linkage rod, and the end of the safety plug rod away from the connecting rod is slidably connected to a rod-penetrating tube, and the inside of the rod-penetrating tube is slidably connected to a retracting rod, and the outside of the retracting rod is provided with an external alloy wire, and a movable tank and a fixed tank are respectively provided on the front and rear sides of the top of the retracting rod, and an inner sleeve valve is fixedly connected to the rear end of the inner wall of the fixed tank, and a sleeve valve through pipe is fixedly connected to the inside of the inner sleeve valve, and a through pipe closed loop is slidably connected to the end of the sleeve valve through pipe away from the fixed tank, and the fixed tank is connected to the battery body. The fixed tank is connected to the wall, the fixed tank is slidably connected to the mobile tank, the two ends of the outer alloy wire are respectively fixedly connected to the top surface of the power module and the side of the retractable rod, the through pipe closed loop is fixedly connected to the inner wall of the mobile tank, the inner wall of the mobile tank is provided with a connecting circular hole, and the connecting circular hole penetrates from the outer wall of the mobile tank to the inner wall, the inner wall of the sleeve valve through pipe is provided with a connecting square hole, and the connecting square hole penetrates from the outer wall of the sleeve valve through pipe to the inner wall, the fixed tank forms a connecting structure with the mobile tank through the sleeve valve through pipe, the retractable rod penetrates from the outer wall of the fixed tank to the outer wall of the mobile tank, the safety plug rod penetrates from one side of the rod tube to the other side, and the safety plug rod penetrates from one side of the retractable rod to the other side A spring is arranged inside the fixed tank, and the two ends of the spring are fixedly connected to the inner sleeve valve and the movable tank respectively. When the connecting rod moves, the connecting rod will pull the connected safety plug rod to allow the safety plug rod to pass through the side of the rod-piercing tube and the contraction rod. At this time, when the temperature of the inner alloy wire is not high, the safety plug rod connected to the connecting rod will not be completely pulled out from the side of the rod-piercing tube and the contraction rod, thereby preventing the connection between the rod-piercing tube and the contraction rod from loosening, ensuring that it can be accurately triggered during spontaneous combustion. When spontaneous combustion occurs in the battery body, the temperature inside the battery body rises, causing the inner alloy wire to completely shrink after being heated. After the inner alloy wire shrinks, the safety plug rod is completely separated from the rod-piercing tube and the contraction rod by pulling the safety plug rod. At this time, the alloy wire outside the rod-piercing tube and the contraction rod begins to contract under the heated state, and contracts into the rod-piercing tube through the contraction rod, so that the contraction rod is separated from the mobile tank and the fixed tank. When the mobile tank and the fixed tank are not bound by the contraction rod, the fixed tank releases the elastic force through the spring between the inner sleeve valve and the mobile tank, pushing the mobile tank away from the fixed tank. At this time, the inner sleeve valve slides with the pipe closed loop through the sleeve valve through the sleeve valve pipe, so that the pipe closed loop no longer blocks the connecting square hole on the side of the sleeve valve through the sleeve valve. At this time, the sodium bicarbonate in the fixed tank enters the mobile tank through the sleeve valve through the sleeve valve pipe and mixes with aluminum sulfate to produce a large amount of carbon dioxide and foam, and the carbon dioxide and foam are sprayed out from the connecting circular hole on the side of the mobile tank.

At the same time, the contact connecting sheet and the energized contact sheet are in a short-circuit state. At this time, the power module cannot transmit electric energy to the energized contact sheet through the contact connecting sheet connected by the wire. By disconnecting the energized line, the power module is prevented from continuing to supply power to cause the temperature to continue to rise, and the possibility of spontaneous combustion due to continuous overheating of the power module is avoided, thereby improving the safety of power supply of the power module.

[0012] The present invention is provided with a linkage rod, a baffle, a fixing plate, a cooling fan, a filter screen, a pressure block slide plate, a voltage block, and a power connection block, so that the cooling fan is in a powered state, and the power module is used to supply power to put the cooling fan in a working state, so that the cooling fan can quickly discharge the heat accumulated in the battery body through the ventilation port, thereby preventing heat accumulation, reducing the high temperature load pressure of the power module, and ensuring the stability of the power supply power of the power module;

[0013] The present invention is provided with a safety plug rod, a rod-penetrating tube, a retractable rod, an outer alloy wire, a mobile tank, a fixed tank, an inner sleeve valve, a sleeve valve through pipe, and a through pipe closed loop.

At this time, the sodium bicarbonate in the fixed tank enters the mobile tank through the sleeve valve through pipe to mix with aluminum sulfate to generate a large amount of carbon dioxide and foam, and the carbon dioxide and foam are sprayed out from the communicating circular holes on the side of the mobile tank, so as to extinguish the burning flame in the battery body, prevent the fire from spreading, and avoid losses caused by the fire.

The end of the safety plug rod 71 away from the connecting rod 55 is slidably connected to a rod-penetrating tube 72, and a retracting rod 73 is slidably connected inside the rod-penetrating tube 72. An outer alloy wire 74 is provided on the outer side of the retracting rod 73. A movable tank 75 and a fixed tank 76 are respectively provided on the front and rear sides of the top of the retracting rod 73. The rear end of the inner wall of the fixed tank 76 is fixed. The inner sleeve valve 77 is fixedly connected, and the inner sleeve valve 77 is fixedly connected with the sleeve valve pipe 78, and the end of the sleeve valve pipe 78 away from the fixed tank 76 is slidably connected with the pipe closed loop 79, the fixed tank 76 is fixedly connected to the inner wall of the battery body 1, and the fixed tank 76 is slidably connected to the mobile tank 75, and the two ends of the outer alloy wire 74 are respectively fixedly connected to the top surface of the power module 4 and the side of the retractable rod 73, and the pipe closed loop 79 is fixedly connected to the inner wall of the mobile tank 75, and the inner wall of the mobile tank 75 is provided with a communicating circular hole, and The communicating circular hole penetrates from the outer wall of the mobile tank 75 to the inner wall, the inner wall of the sleeve valve pipe 78 is provided with a communicating square hole, and the communicating square hole penetrates from the outer wall of the sleeve valve pipe 78 to the inner wall, the fixed tank 76 forms a communicating structure with the mobile tank 75 through the sleeve valve pipe 78, the retracting rod 73 penetrates from the outer wall of the fixed tank 76 to the outer wall of the mobile tank 75, the insurance plug rod 71 penetrates from one side of the rod tube 72 to the other side, and the insurance plug rod 71 penetrates from one side of the retracting rod 73 to the other side, a spring is arranged inside the fixed tank 76, and the two ends of the spring are fixedly connected to the inner sleeve valve 77 and the mobile tank 75 respectively, so that the pipe closed loop 79 no longer blocks the communicating square hole on the side of the sleeve valve pipe 78, at this time, the sodium bicarbonate in the fixed tank 76 enters the mobile tank 75 through the sleeve valve pipe 78 and mixes with aluminum sulfate to produce a large amount of carbon dioxide and foam, and the carbon dioxide and foam are sprayed out from the communicating circular hole on the side of the mobile tank 75, the burning flame in the battery body 1 is extinguished, the fire is prevented from spreading, and the loss caused by the fire is avoided.

[0032] Working principle: a part of the heat on the heat collecting copper sheet 85 is transferred to the protective end shell 51 through the collecting guide sheet 86. The temperature rise of the protective end shell 51 will increase the temperature of the inner alloy wire 53. Since the inner alloy wire 53 is made of nickel-titanium alloy, it begins to shrink after the temperature rises. At this time, the heated inner alloy wire 53 will pull the sliding plate 54 to slide along the guide bar 52. When the sliding plate 54 slides, it will drive the connected connecting rod 55 to move together, so that the connecting rod 55 pulls the terminal block 56. When the temperature inside the protective end shell 51 is high, the contraction distance of the inner alloy wire 53 increases. The contraction of the inner alloy wire 53 will pull the terminal block 56 away from the contact link 510 through the connecting rod 55, so that the terminal block 56 is no longer in contact with the contact link 510. At this time, the contact link 510 and the energized contact piece 57 are in a short-circuit state. At this time, the power module 4 cannot transmit electrical energy to the energized contact piece 57 through the contact link 510 connected by the wire. By disconnecting the energized line, the power module 4 is prevented from continuing to supply power and causing the temperature to continue to rise.

[0033] When the connecting rod 55 moves, the connecting rod 55 will drive the connected connecting rod 55 to pull the baffle 62 and the ventilation port 2 to slide, so that the baffle 62 and the filter 65 in the ventilation port 2 move relative to each other. At this time, the baffle 62 moves and contacts and rubs with the filter 65, so that the filter 65 shakes off the dust through the vibration generated by the friction, so as to prevent the dust attached to the filter 65 from affecting the ventilation. At the same time, after the baffle 62 moves, it no longer blocks the bottom of the ventilation port 2, and the inclined section of the baffle 62 will no longer block the voltage block 67, so that the voltage block 67 moves downward along the pressure block slide plate 66 under the action of the spring sheet, close to the power block 68 connected to the cooling fan 64. At this time, the power block 68 and the power block 67 contact each other, so that the cooling fan 64 is in a powered state, and the power module 4 is used to supply power to put the cooling fan 64 in a working state, so that the cooling fan 64 can quickly discharge the heat accumulated in the battery body 1 through the ventilation port 2;

[0034] When the connecting rod 55 moves, the connecting rod 55 will pull the connected safety plug rod 71, allowing the safety plug rod 71 to pass through the side of the rod tube 72 and the contraction rod 73. At this time, when the temperature of the inner alloy wire 53 is not high, the safety plug rod 71 connected to the connecting rod 55 will not be completely pulled out from the side of the rod tube 72 and the contraction rod 73, thereby preventing the connection between the rod tube 72 and the contraction rod 73 from loosening, ensuring that it can be accurately triggered during spontaneous combustion. When spontaneous combustion occurs in the battery body 1, the internal temperature of the battery body 1 increases, causing the inner alloy wire 53 to completely shrink after being heated. After the inner alloy wire 53 shrinks, it is completely separated from the rod tube 72 and the contraction rod 73 by pulling the safety plug rod 71. At this time, the outer alloy wire 74 that has separated from the rod tube 72 and the contraction rod 73 begins to shrink under the heated state. , the retracting rod 73 is retracted into the rod-piercing tube 72, so that the retracting rod 73 is separated from the mobile tank 75 and the fixed tank 76. When the mobile tank 75 and the fixed tank 76 are not bound by the retracting rod 73, the fixed tank 76 releases the elastic force through the spring between the inner sleeve valve 77 and the mobile tank 75, pushing the mobile tank 75 away from the fixed tank 76. At this time, the inner sleeve valve 77 slides with the pipe closed loop 79 through the sleeve valve pipe 78, so that the pipe closed loop 79 no longer blocks the connecting square hole on the side of the sleeve valve pipe 78. At this time, the sodium bicarbonate in the fixed tank 76 enters the mobile tank 75 through the sleeve valve pipe 78 and mixes with aluminum sulfate to produce a large amount of carbon dioxide and foam, and the carbon dioxide and foam are sprayed out from the connecting circular hole on the side of the mobile tank 75 to extinguish the burning flame in the battery body 1.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
