Description

Technical Field

[0001] The present invention belongs to the technical field of thermal runaway monitoring of energy storage power stations, and in particular relates to a nanoparticle detection device for energy storage power stations. Background Art

[0002] Energy storage power stations are facilities that can convert electrical energy into other forms for storage, and then convert it back into electrical energy to supply the power grid or users when needed. The existence of such power stations makes the power system more flexible and able to cope with fluctuations in energy supply and peak demand. Energy storage power stations can use a variety of technologies to achieve energy storage, such as battery energy storage systems, using batteries as energy storage media.

[0003] During the operation of the energy storage battery pack, when the battery in the energy storage battery system experiences thermal runaway, excessive heat is generated inside the battery and cannot be effectively dissipated, which eventually causes the battery system to enter a state of self-heating and self-reaction uncontrollably, which may cause fire, explosion or other safety accidents. For such thermal runaway situations, nanoparticle detectors are usually used for monitoring. After the energy storage battery pack thermally runs away, it will thermally decompose to produce solid particles (nanoscale microparticles). At this time, these nanoparticles can be detected by nanoparticle detectors.

[0004] The Chinese patent with application number 202221377157.2 relates to a battery fire monitoring and early warning system for a wind-solar energy storage power station. The battery fire monitoring and early warning system for a wind-solar energy storage power station provided by the patent monitors the parameter data of the battery compartment and / or battery pack by setting a fire early warning unit. At the same time, after receiving the early warning signal or fire signal, the fire alarm linkage unit automatically starts the fire extinguishing system according to the established fire extinguishing strategy, realizes automatic fire fighting linkage, and multi-level fire fighting and fire prevention and control; on the one hand, it can extend the battery life, on the other hand, it can reduce the probability of fault accidents, reduce investment costs, make up for the current deficiencies in fire detection technology in wind power and photovoltaic energy storage sites and the re-ignition of fires, and ensure the safe operation of wind-solar energy storage power stations.

[0005] In the prior art, when monitoring the particle situation in the energy storage power station through nanoparticle detectors, the dust and other impurities in the air can easily interfere with the detection results of the particle detectors, causing the nanoparticle detectors to falsely report the detection results. At the same time, some nanoparticle detection structures can only determine whether thermal runaway has occurred, but cannot specifically determine which battery pack has a problem, making it impossible to perform maintenance and repairs in a timely manner, thereby reducing processing efficiency. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention arranges four square channels connected in sequence above the energy storage battery pack, and arranges the detection port downward, so as to quickly detect the changes of air nanoparticles in four different directions of the energy storage battery pack; at the same time, through the cooperation of the vertical detection port and the horizontal arc-shaped square tube, the air entry direction is first changed from vertical to horizontal, and the dust and other debris in the air are initially blocked by changing the direction and gravity, and then the arc-shaped side wall of the arc-shaped square tube is used to make the air continuously collide with the arc-shaped side wall. During the collision process, the dust will be continuously blocked from falling, thereby further blocking the dust and comprehensively reducing the probability of false alarm of the nanoparticle detector.

[0022] (2) The present invention continuously performs forward and reverse cycle operation through the forward and reverse rotating fans. When the forward and reverse rotating fans rotate forward, the air in the energy storage power station enters the detection area through the detection port under the separation of the partition plate. Due to the structural design of the air inlet, the air enters the air inlet through the action of the side wind. A part of the dust and impurities in the detection area are brought into the ventilation area on the other side by the main wind of the forward and reverse rotating fans, and are filtered by the dustproof net. The filtered air is discharged to the outside of the energy storage power station through the ventilation window; when the forward and reverse rotating fans reverse, the forward and reverse rotating fans suck the air outside the ventilation window into the ventilation area through the dustproof net, and then discharge it into the energy storage power station through the detection area and the detection port, thereby realizing ventilation. Due to the setting of the air inlet, the air sucked in at this time will not enter the arc-shaped square tube, thereby realizing ventilation without interfering with the operation of the nanoparticle detector.

[0023] (3) The present invention provides a partition plate. When a forward and reverse fan at a certain position is damaged and stops operating, since there is still a gap between one end of the partition plate and the inner peripheral side wall of the square channel, the forward and reverse fans at other positions can still drive the air below this position to enter, thereby continuing to maintain the detection function at this position, thereby preventing the situation where the air at this position cannot be sucked in in time when the fan is damaged.

[0024] (4) The present invention cooperates with the reversing structure and the regulating tube and controls the control structure. When only particles in a single direction need to be detected, the control tube rotates through the rotation of the second stepper motor, and the closing plate closes the first connecting port. At this time, the first stepper motor rotates to connect the docking groove with the corresponding connecting port. In this way, the nanoparticles in the corresponding direction can enter the guide tube and the control tube in turn through the arc-shaped square tube, and finally enter the detection cavity of the nanoparticle detector to be detected. As a result, under the continuous rotation of the first stepper motor, the docking groove is connected with each connecting port in turn, so that the nanoparticle detector can cyclically detect the particle conditions in each direction of the energy storage battery pack. When the energy storage battery in a certain direction is about to thermally run away, the nanoparticle detector can detect the particle conditions in each direction of the energy storage battery pack in a circular manner. The particle detector can accurately determine the specific location of the energy storage battery, thereby improving the effect of maintenance and inspection; when it is necessary to comprehensively detect nanoparticles in all locations at the same time, the control tube is rotated by the rotation of the second stepper motor, the closing plate is moved away, and the first connecting port connects the air intake pipe with the regulating tube. At this time, nanoparticles in three locations enter the air intake pipe through the arc-shaped square tube, and nanoparticles in the remaining location enter the guide tube through the arc-shaped square tube. Finally, the nanoparticles in the guide tube and the nanoparticles in the air intake pipe are combined in the regulating tube through the second connecting port. After the combination, they enter the detection cavity of the nanoparticle detector through the control tube to be detected, realizing all-round detection, thereby meeting the detection requirements under different environments.

Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0037] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

[0038] Example

[0039] like Figures 1 to 9As shown, a nanoparticle detection device for an energy storage power station includes square channels 100 arranged on all sides, and four of the square channels 100 are connected in sequence; the square channels 100 are located above the energy storage battery pack, and a detection port 110 is connected to one side of the bottom of the square channels 100, and the detection port 110 is arranged downward; forward and reverse fans 140 are installed at the connecting diagonals of adjacent square channels 100, and a dustproof net 120 is connected to the middle of the outer peripheral side wall of the square channels 100, and the dustproof net 120 is connected to the ventilation window of the energy storage power station; the dustproof net 120 can block a certain amount of dust, and the ventilation window can be connected to the outside of the energy storage power station.

[0040] It is worth noting that the forward and reverse fan 140 can realize the switching of the fan blades between forward and reverse rotation, thereby changing the wind direction. The forward and reverse fan 140 can be switched through an external switch or control device and is powered by an external power supply. This is a prior art and will not be described in detail here.

[0041] The inner peripheral side walls of the square channel 100 are connected and installed with an arc-shaped square tube 200, and the air inlet 220 of the arc-shaped square tube 200 extends into the interior of the square channel 100, and the air inlet 220 is located between the adjacent forward and reverse fans 140 and the detection port 110; the outer peripheral side walls of the square channel 100 are plugged with a partition plate 130, and the partition plate 130 is located between the detection port 110 and the dustproof net 120; the partition plate 130 divides the square channel 100 into a ventilation area and a detection area, and the detection port 110 and the air inlet 220 are both located in the detection area;

[0042] It is worth noting that the ventilation area is mainly used for the circulation of air, and the detection area is mainly used for the circulation of air containing nanoparticles, which will be further described in detail below.

[0043] The air outlets of the arc-shaped square tube 200 are connected to the air inlet pipe 300 , and the air outlet end of the air inlet pipe 300 is connected to the nanoparticle detector 400 to send the nanoparticles into the detection cavity of the nanoparticle detector 400 for detection.

[0044] It is worth explaining that the working principle of the nanoparticle detector 400 of the present invention is to detect nanoparticles in the air through its own particle sensor. After the energy storage battery pack has thermal runaway, it can issue an early warning of excessive solid particles (microparticles) volatilized into the air by thermal decomposition, thereby early detection of thermal runaway and other phenomena and taking other measures, such as maintenance or replacement, to prevent fire and other situations. The nanoparticle detector 400 is a prior art and is not described in detail here.

[0045] The present invention arranges four square channels 100 connected in sequence above the energy storage battery pack, and the detection port 110 is arranged downward, so that the changes of air nanoparticles in four different directions of the energy storage battery pack can be quickly detected; at the same time, through the cooperation of the vertical detection port 110 and the horizontal arc-shaped square tube 200, the air entry direction is first changed from vertical to horizontal, and the dust and other debris in the air are initially blocked by changing the direction and gravity, and then the arc-shaped side wall of the arc-shaped square tube 200 acts to make the air continuously collide with the arc-shaped side wall, and the dust will be continuously blocked from falling during the collision, thereby further blocking the dust and comprehensively reducing the probability of false alarm of the nanoparticle detector 400.

[0046] Furthermore, an end surface of the air inlet 220 is arranged toward a side of the adjacent detection port 110 .

[0047] It is worth noting that the end surface size of the air inlet 220 in the schematic diagram is only a schematic diagram and can be adjusted according to the actual wind force, which will not be described in detail here.

[0048] The present invention continuously performs forward and reverse cycle operation through the forward and reverse fan 140. When the forward and reverse fan 140 rotates forward, the air in the energy storage power station enters the detection area through the detection port 110 under the separation of the partition plate 130. Due to the structural design of the air inlet 220, the air enters the air inlet 220 through the action of the side wind. A part of the dust and impurities in the detection area are brought into the ventilation area on the other side by the main wind of the forward and reverse fan 140, and are filtered by the dustproof net 120. The filtered air is discharged to the outside of the energy storage power station through the ventilation window; when the forward and reverse fan 140 reverses, the forward and reverse fan 140 sucks the air outside the ventilation window into the ventilation area through the dustproof net 120, and then discharges it into the energy storage power station through the detection area and the detection port 110, thereby realizing ventilation. Due to the setting of the air inlet 220, the air sucked in at this time will not enter the arc-shaped square tube 200, thereby realizing ventilation without interfering with the operation of the nanoparticle detector 400.

[0049] Furthermore, the angle α between the end face of the air inlet 220 and the cross section of the square channel 100 is in the range of 45°>α>30°. By setting the range of the angle α, the operation of the forward and reverse fan 140 can bring the air entering the detection port 110 into the arc-shaped square tube 200 in the form of side wind.

[0050] Furthermore, the partition plate 130 is inclined toward the dustproof net 120 , and the distance between one end of the partition plate 130 and the inner peripheral side wall of the square channel 100 is d, and the value of d is less than half of the distance between the two side walls of the square channel 100 .

[0051] It is worth noting that since the distance d between one end of the partition plate 130 and the inner peripheral side wall of the square channel 100 is small, the caliber of the detection port 110 is much larger than the gap between the partition plate 130 and the inner peripheral side wall of the square channel 100. Therefore, when the forward and reverse rotating fan 140 rotates forward, the detection area is mainly entered by the air below the detection port 110, and the air in the ventilation area passes less through the gap between the partition plate 130 and the inner peripheral side wall of the square channel 100, so it will not affect the detection of nanoparticles in the air in this direction.

[0052] At the same time, through the provision of the partition plate 130, when the forward and reverse fan 140 at a certain position is damaged and stops working, since there is still a gap between one end of the partition plate 130 and the inner peripheral side wall of the square channel 100, the forward and reverse fans 140 at other positions can still drive the air below this position to enter, thereby continuing to maintain the detection function of this position, to prevent the situation where the air at this position cannot be sucked in time when the fan is damaged.

[0053] Further, the bottom end of the air inlet pipe 300 is closed, and the top end of the air inlet pipe 300 is connected to the nanoparticle detector 400; the side wall of the air inlet pipe 300 is provided with four connection ports 310, and the arc-shaped square tube 200 includes an arc-shaped square tube body 210, one end of the arc-shaped square tube body 210 is an air inlet 220, and the other end of the arc-shaped square tube body 210 is fixedly connected to the connection port 310 corresponding to the air inlet pipe 300. The reversing structure 600 can be connected to a specified arc-shaped square tube 200, which will be further described below.

[0054] Furthermore, a reversing structure 600 is installed in the intake pipe 300, and the reversing structure 600 includes a first stepper motor 630 and a guide tube 610, the bottom end of the guide tube 610 is closed, the output shaft of the first stepper motor 630 passes through the bottom end of the intake pipe 300 and the output shaft is fixedly connected to the bottom end of the guide tube 610; the outer diameter of the guide tube 610 is smaller than the inner diameter of the intake pipe 300, and the side wall of the guide tube 610 is connected and provided with a docking groove 620; when the output shaft of the first stepper motor 630 drives the guide tube 610 to rotate, the docking groove 620 can be docked and connected with the corresponding connecting port 310.

[0055] It is worth noting that the first stepper motor 630 is powered by an external power source and the rotation angle can be controlled externally, for example, each rotation causes the guide tube 610 to rotate 90°. The same is true for the second stepper motor 550 below, which will not be described in detail here.

[0056] Furthermore, the top end of the air intake pipe 300 is fixedly connected with an adjusting cylinder 700, the top and bottom of the adjusting cylinder 700 are both closed, the bottom of the adjusting cylinder 700 is an adjusting plate 720, and a plurality of first connecting ports 740 are evenly arranged in an annular direction on the adjusting plate 720, and the first connecting ports 740 connect the adjusting cylinder 700 with the air intake pipe 300; a connecting pipe 730 is fixedly provided in the middle of the adjusting plate 720, the top end of the guide tube 610 is sealed in contact with the middle of the bottom of the adjusting plate 720, and the connecting pipe 730 connects the adjusting cylinder 700 with the guide tube 610.

[0057] It is worth noting that a layer of sealing rubber may be provided at the top of the guide tube 610 to improve the sealing performance, which will not be described in detail here.

[0058] Furthermore, a control structure 500 is installed in the regulating cylinder 700, and the control structure 500 includes a control tube 510, and the control tube 510 is rotatably inserted on the connecting tube 730, and a plurality of closing plates 540 are evenly arranged in an annular direction on the bottom of the side wall of the control tube 510, and the closing plates 540 correspond one by one to the first connecting ports 740; a plurality of second connecting ports 530 are evenly opened on the side wall of the control tube 510, and the second connecting ports 530 connect the control tube 510 with the regulating cylinder 700; the control tube 510 is arranged outward through the top of the regulating cylinder 700, and the top end of the control tube 510 is connected to the nanoparticle detector 400.

[0059] It is worth noting that the closing plate 540 is used to close the first connecting port 740. When the control tube 510 rotates a certain angle, the closing plate 540 is located above the corresponding first connecting port 740 to close the first connecting port 740, which will be further explained below.

[0060] Furthermore, a first gear 520 is fixedly connected to the top of the side wall of the control tube 510, a second stepper motor 550 is fixedly installed on the top of the adjustment cylinder 700, an output shaft of the second stepper motor 550 is fixedly connected to a second gear 560, and the first gear 520 is meshed with the second gear 560.

[0061] The present invention cooperates with the reversing structure 600 and the regulating cylinder 700 and is controlled by the control structure 500. When only particles in a single side orientation need to be detected, the control tube 510 is rotated by the rotation of the second stepper motor 550, and the closing plate 540 closes the first connecting port 740. At this time, the first stepper motor 630 rotates to connect the docking groove 620 with the corresponding connecting port 310, so that the nanoparticles in the corresponding orientation can enter the guide tube 610 and the control tube 510 in turn through the arc-shaped square tube 200, and finally enter the detection cavity of the nanoparticle detector 400 for detection. As a result, under the continuous rotation of the first stepper motor 630, the docking groove 620 is connected with each connecting port 310 in turn, so that the nanoparticle detector 400 can cyclically detect the particle conditions in each orientation of the energy storage battery pack. When the energy storage battery in a certain orientation is about to thermally run away, the nanoparticle detector 400 can detect the particle conditions in each orientation of the energy storage battery pack in a circular manner. The particle detector 400 can accurately determine the specific orientation of the energy storage battery, thereby improving the effect of maintenance and inspection; when it is necessary to comprehensively detect nanoparticles in all orientations at the same time, the control tube 510 is rotated by the rotation of the second stepper motor 550, the closing plate 540 is moved away, and the first connecting port 740 connects the air intake pipe 300 with the regulating tube 700. At this time, nanoparticles in three orientations enter the air intake pipe 300 through the arc-shaped square tube 200, and the nanoparticles in the remaining one orientation enter the guide tube 610 through the arc-shaped square tube 200. Finally, the nanoparticles in the guide tube 610 and the nanoparticles in the air intake pipe 300 are combined in the regulating tube 700 through the second connecting port 530. After the combination, they enter the detection cavity of the nanoparticle detector 400 through the control tube 510 to be detected, thereby realizing all-round detection, thereby meeting the detection requirements under different environments.

[0062] Furthermore, a support frame 410 and an air inlet end 420 are provided at the bottom of the nanoparticle detector 400 . The support frame 410 is fixedly connected to the top of the regulating cylinder 700 . The air inlet end 420 is inserted into the control tube 510 and is rotatably connected to the control tube 510 .

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
