[0034] Example 1
[0035] Reference Figures 1 to 6 , which is the first embodiment of the utility model, provides a ventilation mechanism, which can solve the problem of filtering, adsorbing and discharging the toxic gas leaked in the battery cabinet to the outside of the cabinet, and preventing the staff from suddenly contacting a large amount of toxic gas and causing physical damage, including a storage cabinet component 100, a filter component 200 arranged on the storage cabinet component 100, and a ventilation component 300 arranged on the filter component 200; wherein the ventilation component 300 includes a tube body assembly 301 and a driving assembly 302 arranged in the tube body assembly 301.
[0036] Specifically, the tube assembly 301 includes a ventilation tube 301a, a tube inner groove 301b provided on the ventilation tube 301a, a ventilation hole 301c provided on the ventilation tube 301a, an air inlet hole 301d provided on the ventilation tube 301a, and an inclined surface 301e provided on the air inlet hole 301d. The driving assembly 302 includes a driving column 302a, a contact surface 302b provided on the driving column 302a, a column groove 302c provided on the driving column 302a, and a driving spring 302d fixedly connected in the column groove 302c. The ventilation hole 301c passes through the top of the ventilation pipe 301a and is connected to the inner groove 301b of the tube, and there are multiple ventilation holes 301c, which is conducive to the rapid outflow of filtered gas. One end of the driving spring 302d is fixedly connected to the top wall of the inner groove 301b of the tube, and the other end of the driving spring 302d is fixedly connected to the bottom wall of the column groove 302c. The driving column 302a is placed in the inner groove 301b to slide, and the outer diameter of the driving column 302a is smaller than the diameter of the inner groove 301b of the tube, which is conducive to the outflow of filtered gas. The diameter of the air inlet hole 301d is smaller than the diameter of the driving column 302a, and the inclined surface 301e is adapted to the abutment surface 302b. When the driving spring 302d is in a normal state, the inclined surface 301e fits the abutment surface 302b.
[0037] Furthermore, the storage cabinet component 100 includes a storage cabinet body 101 and a through hole 102 provided on the storage cabinet body 101. The filter component 200 includes a blower 201, an acid-base neutralization treatment tube 202 fixedly connected to the blower 201, and an activated carbon adsorption tube 203 fixedly connected to the acid-base neutralization treatment tube 202. A battery is placed in the storage cabinet body 101, the through hole 102 is provided above the storage cabinet body 101, and the through hole 102 is fixedly connected to the air intake port of the blower 201, and the air outlet of the blower 201 is fixedly connected to the acid-base neutralization treatment tube 202.
[0038] During use, when it is necessary to discharge the toxic gas leaked in the battery cabinet, first start the blower 201, the air inlet of the blower 201 sucks out the toxic gas inside the storage cabinet body 101, and then transports the toxic gas to the acid-base neutral treatment tube 202 through the air outlet of the blower 201 for preliminary treatment. The harmful gas after preliminary treatment is then adsorbed by the activated carbon adsorption tube 203 for harmful substance treatment. At this time, the harmful gas can be discharged into the air after being treated. At this time, the gas pushes the drive column 302a upward when passing through the air inlet hole 301d. At this time, the drive spring 302d contracts, and the abutment surface 302b separates from the inclined surface 301e. At this time, the gas flows into the inner groove 301b of the tube and then flows out from the vent. After that, the staff will be less exposed to harmful gases when opening the cabinet door, so it will not cause damage to the body.
[0039] In summary, by setting up the ventilation component 300, the filtered gas can only be output in one direction, thereby preventing the gas from flowing back and mixing with the harmful gas that has not been treated, which is conducive to quickly discharging the harmful gas from the storage cabinet body 101, thereby purifying the air in the cabinet, and preventing the staff from being exposed to a large amount of harmful gas when opening the storage cabinet body.
[0040] Example 2
[0041] Reference Figures 1 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a barrier component 303. The barrier component 303 can be used to close the ventilation hole 301c when the air inside the storage cabinet body 101 is not purified to prevent dust from falling into the ventilation hole 301c and causing the tube body component 301 to be blocked. The ventilation component 300 also includes a barrier component 303; the barrier component 303 includes an inner column 303a, an inner groove 303b opened on the inner column 303a, a hole-blocking column 303c fixedly connected to the inner column 303a, an arc surface 303d arranged on the hole-blocking column 303c, a ladder block 303e fixedly connected to the inner column 303a, and an upper arc groove 303f opened on the inner column 303a. The outer diameter of the inner column 303a is matched with the diameter of the column groove 302c, and one end of the inner column 303a is placed in the column groove 302c to slide, the diameter of the inner groove 303b is matched with the driving spring 302d, and the hole blocking column 303c is matched with the ventilation hole 301c. The Shenzhen arc surface 303d is conducive to the smooth entry of the hole blocking column 303c into the ventilation hole 301c, and also makes it difficult for dust to accumulate on the hole blocking column 303c.
[0042] Furthermore, the driving assembly 302 also includes a lower arc groove 302e, a limiting block 302f fixedly connected to the driving column 302a, and a ladder limiting groove 302g provided on the driving column 302a. The lower arc groove 302e is adapted to the upper arc groove 303f, and the starting point of the lower arc groove 302e and the upper arc groove 303f is at the same position, and the turning direction is also the same, but the lower arc groove 302e is downward, and the upper arc groove 303f is upward. The ladder limiting groove 302g is adapted to the ladder block 303e, and the ladder block 303e slides in the ladder limiting groove 302g. By setting the ladder limiting groove 302g and the ladder block 303e, it is beneficial to limit the inner column 303a to only move up and down, and cannot rotate. The ventilation component 300 further includes a sliding component 304 disposed on the baffle component 303; the sliding component 304 includes a sliding column 304a, an inner plate 304b fixedly connected to the sliding column 304a, and an outer plate 304c fixedly connected to the sliding column 304a. The pipe body component 301 further includes a limiting groove 301f provided on the side of the inner groove 301b of the pipe. The sliding column 304a slides in the upper arc groove 303f and the lower arc groove 302e, the inner plate 304b fits and slides with the inner groove 303b, the outer plate 304c fits and slides with the outer wall of the driving column 302a, the limiting block 302f fits and the limiting groove 301f, and the limiting block 302f slides in the limiting groove 301f. The setting of the limiting block 302f and the limiting groove 301f is conducive to limiting the driving block, so that the driving column 302a can only move up and down but cannot rotate.
[0043] During use, when it is necessary to filter and discharge the toxic gas in the storage cabinet, when the gas passes through the air inlet 301d, the driving column 302a is pushed upward, and the driving spring 302d is contracted, and the abutment surface 302b is separated from the inclined surface 301e. At this time, when the driving column 302a moves upward, it will drive the sliding column 304a to slide downward in the sliding groove. At this time, the sliding column 304a slides downward in the sliding groove, which will drive the sliding column 304a to slide upward in the upper sliding groove, and then drive the inner column 303a to slide downward in the column groove 302c. When the sliding column 304a slides in the lower arc groove 302e and the upper arc groove 303f, the upper arc groove 303f is When the groove 303f coincides with the other starting point of the lower arc groove 302e, the hole-blocking column 303c is completely separated from the ventilation hole 301c and is at a certain distance from the ventilation hole 301c. At this time, the gas flows into the inner groove 301b of the tube and then flows out from the vent; when the harmful gas inside the storage cabinet is completely filtered and discharged, at this time, no gas enters the air inlet 301d. At this time, the driving spring 302d is reset, driving the driving column 302a to reset, and then driving the inner column 303a to reset. At this time, the hole-blocking column 303c enters the ventilation hole 301c, and the arc surface 303d extends out of the ventilation hole 301c to prevent external dust from falling into the ventilation hole 301c and causing the tube body assembly 301 to be blocked.
[0044] Example 3
[0045] Reference Figures 7 to 9 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a method for monitoring leakage based on VOC gas in a battery cabinet, which solves the problem of inaccurate detection of battery leakage. It includes the ventilation mechanism in the above embodiment, including a VOC gas detector, a storage cabinet component 100, and an I.MX9352 control system; wherein, the VOC gas detector is controlled by I.MX9352 to detect whether the battery in the storage cabinet component 100 has leaked and produced harmful gases. When the VOC gas detector detects the leakage gas, the storage cabinet component 100 is started to exhaust, and the toxic gas is filtered, adsorbed and discharged outside the cabinet to purify the air quality in the cabinet.
[0046] Specifically, the VOC gas detection device is a device that ionizes VOC molecules by high-energy photons emitted by ultraviolet lamps. Under the action of the bias electric field, electrons and VOC ions are separated. The extremely weak ion flow is collected and converted into an analog signal output related to the concentration after filtering, multi-stage amplification and linear processing, which is used to detect the volatile gas emitted by battery leakage.
[0047] Furthermore, the VOC gas detection device includes a detection gas collection hole, an air compressor, a cavity air intake pipe, a battery to be tested, a cavity, and a gas detector. The detection gas collection hole will collect the gas in the battery cabinet at regular intervals, and the air compressor will compress the collected gas and send it into the cavity through the cavity air intake pipe. The battery to be tested will undergo ion separation and the corresponding conclusion will be drawn through the gas detector.
[0048] When in use, it is controlled by I.MX9352 and can be used to receive alarm signals from the gas detection module, and can control the operation of the VOC gas detection device to make it reach working conditions, extract gas samples once an hour, and when it detects leakage of volatile gas, it can control the start-up of the storage cabinet component 100 to perform exhaust filtration and purify the air in the cabinet, and at the same time send signals to the host computer remotely to achieve remote monitoring.
[0049] In summary, the VOC gas leakage monitoring method improves the detection accuracy and sensitivity of battery leakage inside the storage cabinet component 100, and can also realize remote monitoring of the system, real-time alarm, and immediately notify the operator for quick inspection.
