Description

Technical Field

[0001] The utility model belongs to the technical field of battery monitoring, and in particular relates to a battery monitoring device based on a cloud platform. Background Art

[0002] Batteries are widely used. With the development of their technology, their application areas will continue to expand and the market space will become larger and larger. Batteries will bulge after long-term use. In severe cases, it will cause battery leakage, rupture, burn, and even cause safety accidents such as explosion and fire. Therefore, it is necessary to detect battery bulging in time.

[0003] The existing patent authorization number is: CN214587156U, which discloses a battery monitoring device based on a smart cloud platform. The battery monitoring device based on the smart cloud platform includes a monitoring box, a groove is provided on the inner bottom wall of the monitoring box, and pressure sensing blocks are fixedly connected to both sides of the inner bottom wall of the groove. A control box is fixedly connected to the back of the monitoring box, a pressure signal receiver is fixedly connected to one side of the inner bottom wall of the control box, and a smoke signal receiver is fixedly connected to the middle of the inner bottom wall of the control box; the pressure sensing block and the smoke detection block detect the battery and the inside of the monitoring box, and then the detected data are respectively transmitted to the pressure signal receiver and the smoke signal receiver, the battery is analyzed and processed, and then the signal processor is used to transmit the analyzed data to a computer or mobile phone APP, so as to ensure that the staff can monitor and manage the battery anytime and anywhere, thereby improving the monitoring efficiency of the battery; generally speaking, the battery A high-hardness protective structure will be set at the top and bottom. The battery bulging failure mostly occurs on the side of the battery. After analyzing the above monitoring device, it is found that the core component of its monitoring is to use the force change of the pressure sensor to determine the battery bulging damage failure. Although this method can detect the bulging failure in time, in the actual installation and design process, due to the relatively large volume of the battery, when setting the pressure sensor, it is necessary to evenly distribute multiple groups on multiple sides of the battery to ensure that the stress points on the outside of the battery can be fully covered. In this way, more pressure sensors will be required, and when the pressure sensor is used for fault monitoring, the pressure sensor needs to be directly or indirectly in contact with the outer wall of the battery, which will reduce the air flow outside the battery, affecting the heat discharge during normal operation of the battery, and thus to a certain extent, it will also increase the failure rate of the battery.

[0004] Therefore, in view of the above-mentioned problems, the present application proposes a technical solution that can solve the problems. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a battery monitoring device based on a cloud platform, aiming to solve the problem.

[0006] The utility model is implemented as follows: a battery monitoring device based on a cloud platform comprises: a monitoring box and a battery; a battery positioning groove is provided at the bottom of the monitoring box, and the battery base is plugged into the positioning groove to stably install the battery inside the monitoring box, and the monitoring box and the battery are spaced apart, and two groups of monitoring mechanism power lifting columns and two groups of monitoring mechanism sliding limit columns are detachably installed at the bottom of the monitoring box corresponding to the outer side of the top of the battery positioning groove, and the two groups of monitoring mechanism power lifting columns and the two groups of monitoring mechanism sliding limit columns are symmetrically arranged at the two ends of the diagonal top of the positioning groove, and a monitoring mechanism is arranged between the adjacent monitoring mechanism power lifting columns and the monitoring mechanism sliding limit columns, and the monitoring mechanism is used for regular real-time monitoring of the side bulging fault of the battery, and the monitoring mechanism comprises a monitoring device close to the battery A rectangular flame-retardant explosion-proof rubber net is arranged on the outer wall of the pool. Both ends of the flame-retardant explosion-proof rubber net are stretched to be straight and longitudinally slidably connected to the side walls of the monitoring mechanism power lifting columns and the sliding limit columns of the monitoring mechanism on both sides. A group of laser ranging components are arranged on the outer lifting side of the flame-retardant explosion-proof rubber net. The laser ranging components move up and down along the flame-retardant explosion-proof rubber net to measure the width of the flame-retardant explosion-proof rubber net at each height. Since the flame-retardant explosion-proof rubber net is arranged in a rectangular structure, the width corresponding to each height above and below is the same. Once the laser ranging component measures different widths, it means that the flame-retardant explosion-proof rubber net at the corresponding height has a bulging problem, that is, the bulging bulge will hinder the laser ranging component from measuring the normal width of the flame-retardant explosion-proof rubber net, thereby automatically monitoring the battery for faults.

[0007] The utility model provides a battery monitoring device based on a cloud platform. By arranging a flame retardant and explosion-proof rubber net on the outer side of the battery, utilizing the flame retardant and explosion-proof properties of the flame retardant and explosion-proof rubber net that are easy to deform under stress, and cooperating with the operation of a reflective lens channel and a laser ranging sensor, accurate real-time fault monitoring of the battery is achieved without affecting the heat release during the operation of the battery. By arranging four groups of laser ranging sensors, full coverage monitoring of the outer side of the battery can be achieved, thereby reducing the monitoring cost to a certain extent.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0016] like Figure 1-5As shown, it is a structural diagram of a battery monitoring device based on a cloud platform provided by an embodiment of the utility model, comprising: a monitoring box 10 and a battery 11; a battery positioning groove is provided at the bottom of the monitoring box 10, and the base of the battery 11 is plugged into the positioning groove, so that the battery 11 is stably installed inside the monitoring box 10, and the monitoring box 10 and the battery 11 are spaced apart, and two groups of monitoring mechanism power lifting columns 12 and two groups of monitoring mechanism sliding limit columns 16 are detachably installed at the bottom of the monitoring box 10 corresponding to the outer side of the top of the battery positioning groove, and the two groups of monitoring mechanism power lifting columns 12 and the two groups of monitoring mechanism sliding limit columns 16 are symmetrically arranged at the two ends of the diagonal top of the positioning groove, and a monitoring mechanism is arranged between adjacent monitoring mechanism power lifting columns 12 and monitoring mechanism sliding limit columns 16, and the monitoring mechanism is used to perform regular real-time monitoring of the side bulging fault of the battery 11, and the monitoring mechanism It includes a rectangular flame-retardant and explosion-proof rubber net 17 arranged near the outer wall of the battery 11. Both ends of the flame-retardant and explosion-proof rubber net 17 are stretched to be straight and longitudinally slidably connected to the side walls of the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 on both sides. A group of laser ranging components are lifted and lowered on the outer side of the flame-retardant and explosion-proof rubber net 17. The laser ranging components move up and down along the flame-retardant and explosion-proof rubber net 17 to measure the width of the flame-retardant and explosion-proof rubber net 17 at each height. Since the flame-retardant and explosion-proof rubber net 17 is set to a rectangular structure, the width corresponding to each height above and below is the same. Once the laser ranging component measures different widths, it means that the flame-retardant and explosion-proof rubber net 17 at the corresponding height has a bulging problem, that is, the bulging bulge will hinder the laser ranging component from measuring the normal width of the flame-retardant and explosion-proof rubber net 17, thereby automatically monitoring the battery 11 for faults.

[0017] In the embodiment of the utility model, a plurality of heat dissipation holes (not shown) are evenly arranged on the wall of the monitoring box 10, and the interval distribution between the monitoring box 10 and the battery 11 is coordinated to ensure that the heat generated by the battery 11 during operation can be smoothly and quickly released outwards; in order to keep the flame retardant and explosion-proof rubber net 17 flame retardant, explosion-proof and elastic, a nitrile rubber material is generally used, which is very easy to deform when pushed by the outer bulge of the battery 11;

[0018] The distance between the flame retardant and explosion-proof rubber net 17 and the outer wall of the battery 11 is less than Xmm. By controlling the distance between the two within Xmm, a buffer space is provided for the thermal expansion of the battery fluid inside the battery 11. Once the distance between the two exceeds Xmm, it means that the battery 11 is very likely to have a bulging failure, which should be handled in time. The setting of the X size depends on the type of each battery 11 and the change in the distance to the outside of the battery 11 caused by the thermal expansion of the internal battery fluid. Therefore, in the actual design process, it is necessary to conduct a thermal expansion test on the battery 11 in advance, and then set the spacing between the flame retardant and explosion-proof rubber net 17 and the outside of the battery 11.

[0019] In an example of the utility model, the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 are set to an L-shaped structure, and a plurality of bayonet pins 13 are evenly installed at the bottom of the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16. A bayonet pin 13 is provided at the bottom of the monitoring box 10 corresponding to the bayonet pin 13. The bayonet pin 13 is connected to the bayonet slot 14, thereby the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 are detachably installed on one side of the top of the battery positioning slot, and the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 are placed on the battery. At the diagonal end of the battery positioning groove, the L-shaped structure is used to fit the inner sides of the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 with the corners of the battery 11 installed inside the battery positioning groove, and then the battery 11 is further fixed in the battery positioning groove. The contact of the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 with the outer wall of the battery 11 only occupies a small area at the outer edge of the battery 11. Basically, there will be no bulging problem in this area, so it will not have a substantial impact on the monitoring of the battery 11.

[0020] As a preferred embodiment of the utility model, a flame retardant and explosion-proof rubber net 17 is fixedly installed with a net end plate 18 on one edge of the net end plate 18. Under the connection of the net end plate 18, the flame retardant and explosion-proof rubber net 17 in a normal stress-free state can be stretched to be straight. Slide bars 19 are installed on the outer walls of the net end plates 18 on both sides of the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16. The side walls of the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 corresponding to the slide bars 19 are provided with slide rails 20 with top openings. The slide bars 19 are installed and disassembled along the slide rails 20 for longitudinal sliding.

[0021] In order to increase the stability of the flame retardant and explosion-proof rubber net 17 after being installed through the slide bar 19 and the slide rail 20 , the slide bar 19 and the slide rail 20 are generally set to have a T-shaped cross-section, that is, to prevent the slide bar 19 from moving laterally along the slide rail 20 .

[0022] As a preferred embodiment of the utility model, the laser ranging component includes a power component slot 21 opened inside the corner of the power lifting column 12 of the monitoring mechanism, a servo motor is fixedly installed at the bottom of the power component slot 21, a lead screw 22 is connected to the top of the servo motor, a nut is threadedly connected to the lead screw 22, and a guide device for limiting its rotation is provided on the nut, and a lifting slide is opened on the lead screw 22 toward the flame-retardant and explosion-proof rubber nets 17 on both sides, and a fixing rod 23 is fixedly installed on both sides of the nut located at the lifting slide, and the end of the fixing rod 23 extends to the outside of the lifting slide and is installed with a laser ranging sensor 24, and the output end of the laser ranging sensor 24 is distributed close to the outer surface of the flame-retardant and explosion-proof rubber net 17, and a reflective lens track 25 is provided on the outer side wall of the sliding limit column 16 of the monitoring mechanism corresponding to one side of the laser ranging sensor 24, and the laser ranging sensor 24 is started to operate and the laser diode inside it is used to aim at the target reflective lens track 25 to emit laser pulses, which are reflected by the reflective lens track 25 The laser is scattered in all directions, and part of the scattered light returns to the sensor receiver inside the laser ranging sensor 24, and then is received by the optical system and imaged onto the avalanche photodiode. The avalanche photodiode is an optical sensor with an internal amplification function. It can detect extremely weak light signals, record and process the time from the light pulse being sent to the return being received, and can measure the target distance. The above-mentioned operating principle between the laser ranging sensor 24 and the reflective lens track 25 belongs to the prior art and will not be described in detail. When the flame retardant and explosion-proof rubber net 17 is not deformed by the convexity, the distance measurement time between the laser ranging sensor 24 and the reflective lens track 25 remains unchanged. Once a bulge appears on the outside of the battery 11, a thrust is applied to the flame retardant and explosion-proof rubber net 17 to cause deformation. Then, under the premise that the nut drives the laser ranging sensor 24 to move up and down along the flame retardant and explosion-proof rubber net 17, when it encounters a deformation, it will be accurately discovered, thereby achieving accurate monitoring.

[0023] As a preferred embodiment of the utility model, the laser ranging sensor 24 can be connected to the terminal in a wired or wireless manner, and then the changes in the detected distance and time are displayed in a graphical manner to form a monitoring mode based on a cloud platform, thereby providing intuitive and accurate judgment for monitoring; the terminal can be a remote terminal (mobile phone) or a computer and other devices, and the specific choice depends on the actual situation.

[0024] The above embodiment of the utility model provides a battery monitoring device based on a cloud platform. When the device is in operation, the battery 11 is pre-installed inside the monitoring box 10, and then the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16 are respectively installed at the corners of the battery 11 through the latch 13 and the slot 14 to limit them, and then the flame-retardant and explosion-proof rubber net 17 is slidably installed between the monitoring mechanism power lifting column 12 and the monitoring mechanism sliding limit column 16, leaving a suitable distance between the flame-retardant and explosion-proof rubber net 17 and the outer side of the battery 11, and then the servo motor is regularly started to drive the laser ranging sensor 24 to move up and down along the flame-retardant and explosion-proof rubber net 17, and the width of the flame-retardant and explosion-proof rubber net 17 is detected in real time, and the distance detection result between the laser ranging sensor 24 and the reflective lens 25 is used to judge whether deformation occurs on the flame-retardant and explosion-proof rubber net 17, and then judge whether there is a bulging fault on the outer side of the battery 11, thereby realizing fault monitoring of the battery 11 during operation.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
