Description

Technical Field

[0001] This invention relates to a device base, and more particularly to a safety base for mounting electrical equipment. Background Technology

[0002] A battery discharger is a key device used for battery discharge maintenance, capacity testing, and performance evaluation. It obtains the battery's true capacity and performance parameters by simulating the actual discharge process. During the discharge test, the battery needs to establish an electrical connection with the discharger, and both the discharger and the battery under test must be mounted on a corresponding support structure. The mounting base, as the basic support component carrying the discharger and the battery under test, directly affects the safety, reliability, and ease of operation of the discharge test.

[0003] Currently, battery dischargers and their associated batteries are typically placed directly on ordinary workbenches or simple supports for discharge testing. The mounting base primarily serves a supporting and fixing function. These bases are often integral platform structures. When a battery catches fire or explodes during discharge due to internal short circuits, thermal runaway, or other reasons, the high-temperature flames and shock waves can easily spread along the base surface directly to the discharger body and other adjacent batteries, causing equipment damage or even secondary accidents. However, the aforementioned bases with isolation structures have several shortcomings. First, the installation of isolation baffles or compartments complicates the overall structure of the base, increasing manufacturing costs and installation difficulty. Furthermore, the isolation components are often fixed, making it impossible to flexibly adjust the range and position of the isolation area according to actual testing needs. Secondly, after adding isolation structures, existing bases often neglect the proper layout of heat dissipation channels, and the fixed isolation components are inconvenient to disassemble and clean, posing difficulties for daily maintenance and equipment repair.

[0004] Therefore, this case aims to provide a safety base for the installation of electrical equipment. Under normal use, the base can ensure stable and reliable support. At the same time, when the battery discharge becomes unstable, it can isolate the problem area in an adjustable or triggerable manner to prevent the spread of flames, high-temperature gases and shock waves to other areas, thus taking into account the base's versatility, safety, heat dissipation and ease of maintenance. Summary of the Invention

[0005] This invention provides a safety base for installing electrical equipment, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: A safety base for mounting electrical equipment, comprising: The supporting frame body includes an upper support plate for supporting electrical equipment, and a lower base plate is connected to the lower part of the upper support plate via a connecting seat; The equipment installation platform includes a main support platform movably disposed at the opening in the middle of the upper support plate, and an auxiliary support platform is disposed adjacent to the front end of the main support platform; The multifunctional connecting assembly has several flow ports on the main support platform. The multifunctional connecting assembly includes a receiving component disposed below the main support platform. The receiving component and the main support platform are spaced apart in the vertical direction. A guide component is disposed on the outside of the connecting seat. When the main support platform and the auxiliary support platform are at the same horizontal height, the guide component is activated. When the main support platform descends, the main support platform sinks into the interior of the support frame body, causing the bottom end of the electrical equipment to abut against the receiving component. The movable lateral constraint member has swing grooves on both sides of the upper support plate corresponding to the main support platform. The movable lateral constraint member is rotatably installed in the swing groove. The movable lateral constraint member is laterally linked with the main support platform. When the main support platform descends, the movable lateral constraint member flips upward relative to the upper support plate and points towards the electrical equipment.

[0007] As a further improvement, the electrical equipment includes a battery discharger and a battery to be tested. A temperature sensor is provided on the battery discharger on the auxiliary support platform. A fixed motor is provided in the connecting seat for pressing the battery to be tested against the battery discharger. The fixed motor is electrically connected to the temperature sensor. When the temperature sensor detects that the temperature is too high, the fixed motor retracts.

[0008] As a further improvement, the auxiliary support platform is provided with a heat sink that fits against the rear end of the battery discharger.

[0009] As a further improvement, the receiving component includes a grounding seat fixed to the upper end of the lower base plate. The grounding seat is electrically connected to the temperature sensor. An elastic connecting seat is connected to the upper end of the grounding seat. A grounding post is provided on the top of the grounding seat, located inside the elastic connecting seat. After the main support platform moves down, it contacts the grounding post.

[0010] As a further improvement, the elastic connecting seat includes a first electromagnet connected to a grounding seat. A spring is connected to the upper end of the first electromagnet, and a second electromagnet is connected to the top of the spring. The top of the second electromagnet is fixed to the lower end of the main support platform. When the first electromagnet is energized, it pulls the second electromagnet downward, causing the main support platform to descend.

[0011] As a further improvement, the flow guide is a fan. When the flow port is connected to the inside of the connector, the flow guide draws out the heat generated during battery discharge from the bottom.

[0012] As a further improvement, two turnover cylinders are provided on the outer side of the swing groove. The movable lateral constraint includes a rotating rod rotatably installed in the turnover cylinder. An isolation plate is sleeved on the outside of the rotating rod. The isolation plate is connected to the main support platform through a linkage. The isolation plate is raised or placed flat as the main support platform rises and falls. An external pipe is connected to the lower end of the isolation plate.

[0013] As a further improvement, the isolation plate includes a rotating end sleeved on the rotating rod, and an isolation plate surface is connected to the rotating end. The end of the isolation plate surface facing the battery is provided with several positive through-holes, and the bottom end of the isolation plate surface is provided with several oblique through-holes. The bottom surface of the isolation plate surface is connected to an external through-pipe.

[0014] As a further improvement, the linkage is a plurality of steel cables, one end of which is welded to the main bearing platform and the other end of which is wound around the isolation plate.

[0015] As a further improvement, the external conduit includes a flexible hose portion that is connected to the bottom surface of the isolation plate, and the flexible hose portion is connected to a straight pipe portion that leads to the outside of the connector.

[0016] The beneficial effects of this invention are: Existing bases, after adding isolation structures, often neglect the reasonable layout of heat dissipation channels. Therefore, this invention, through the setting of multifunctional connecting components, can dissipate heat from the electrical equipment through the flow port on the main support platform during normal discharge, thereby quickly removing the heat generated during discharge. Once the temperature of the electrical equipment reaches the threshold, the increased temperature may lead to leakage, which will affect the entire discharge production line. This invention can also quickly lower the main support platform, allowing the electrical equipment on the main support platform to contact the receiving component set at the bottom through the port, and ground through the receiving component, thereby quickly conducting away the current in the event of leakage. Furthermore, because the main support platform sinks at this time, the discharge process of the electrical equipment is directly disconnected, making the electrical equipment safer on the base.

[0017] When the battery under test is discharging, pressure is applied to make it contact the battery discharger, thus ensuring the discharge effect. However, if the main support platform needs to be lowered, this limiting will affect the isolation effect. Therefore, this invention sets the fixing motor of the battery under test in a position away from the battery discharger and electrically connects the fixing motor to the temperature sensor on the battery discharger. The temperature sensor will detect the temperature of the battery under test, and when it detects that the temperature of the battery under test is too high, the fixing motor will automatically release, so that the connection between the battery under test and the battery discharger is no longer tight, and then it will be directly disconnected as the main support platform is lowered.

[0018] The battery discharger generates a lot of heat during use. Therefore, this invention provides a heat sink at the rear end of the battery discharger to reduce its temperature and thus avoid affecting the temperature of the battery under test.

[0019] When the receiving component is not overloaded during the discharge process, it is necessary to maintain a flow state between the flow port and the connecting seat to avoid overheating of the bottom of the battery. Under normal conditions, it is also necessary to stably support the battery under test. Therefore, the grounding seat of the receiving component of the present invention is connected to the main support platform through an elastic connecting seat. The elastic connecting seat can support the main support platform, and when the main support platform needs to be lowered, it can be compressed to allow the battery under test to contact the grounding post.

[0020] The elastic connector also adjusts its extension and retraction based on the temperature of the battery under test. When the temperature of the battery under test is too high, the grounding seat is energized by the electrical signal of the temperature sensor, which in turn energizes the first electromagnet. The first electromagnet attracts the second electromagnet, which compresses the spring and pulls the main support platform downward, thereby enabling the main support platform to drive the battery under test to sink.

[0021] Existing base isolation components mostly adopt fixed installation methods, which cannot flexibly adjust the range and position of the isolation area according to actual testing needs. Therefore, the present invention uses a movable lateral constraint to lift the movable lateral constraint under normal conditions, such as when a large device is discharging at a low current. In this case, the discharge process is safe and isolation is not required. However, when a small battery is discharging rapidly, the sinking of the main support platform caused by the high temperature of the battery under test will directly drive the movable lateral constraint to rise. This will lift the movable lateral constraint from the swing slot and isolate it on both sides of the electrical equipment, thereby preventing the high temperature of the electrical equipment from affecting other surrounding discharge equipment. After the abnormal state is resolved, the movable lateral constraint can be reset, thereby improving the flexibility of the entire base.

[0022] In normal conditions, the movable lateral constraint is flush with the entire upper support plate. Therefore, the rotating rod of the movable lateral constraint of the present invention cooperates with the embedded rotating cylinder, and the isolation plate is connected to the rotating rod to achieve a rotatable effect. The isolation plate is then linked with the main support platform through the linkage component, so that the synergistic effect of the isolation plate and the main support platform can be achieved and their movements can be synchronized.

[0023] When isolating, the isolation plate not only provides physical isolation but also chemical isolation. This invention has an external pipe at the lower end of the isolation plate, which is connected to an external fire extinguishing medium. This allows the positive and negative ports to be aligned with the battery to be tested after the isolation plate is raised. The medium is then introduced through the external pipe to force-cool the battery. Through chemical and physical isolation, the entire isolation process is made more stable.

Detailed Implementation

[0033] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Reference Figures 1 to 7 As shown, a safety base for installing electrical equipment includes: a support frame body 1, comprising an upper support plate 101 for supporting the electrical equipment, with a lower base plate 103 connected to the lower part of the upper support plate 101 via a connecting seat 102; an equipment mounting platform 2, comprising a main support platform 201 movably disposed at the opening in the middle of the upper support plate 101, with an auxiliary support platform 202 adjacent to the front end of the main support platform 201; and a multi-functional connecting assembly, wherein the main support platform 201 has a plurality of flow ports 2011, and the multi-functional connecting assembly includes a receiving member 301 disposed below the main support platform 201, the receiving member 301 being vertically spaced from the main support platform 201, and the outer side of the connecting seat 102 being provided with... The guide member 302 is activated when the main support platform 201 and the auxiliary support platform 202 are at the same horizontal height. When the main support platform 201 descends, it sinks into the interior of the support frame body 1, causing the bottom end of the electrical equipment to abut against the support member 301. The movable lateral constraint member 4 has swing grooves 2012 on both sides of the upper support plate 101 corresponding to the main support platform 201. The movable lateral constraint member 4 is rotatably installed in the swing grooves 2012. The movable lateral constraint member 4 is laterally linked with the main support platform 201. When the main support platform 201 descends, the movable lateral constraint member 4 flips upward relative to the upper support plate 101 and points towards the electrical equipment.

[0036] Existing bases, after adding isolation structures, often neglect the reasonable layout of heat dissipation channels. Therefore, this invention, through the setting of multifunctional connecting components, can dissipate heat from the electrical equipment through the flow port 2011 on the main support platform 201 during normal discharge, thereby quickly removing the heat generated during discharge. Once the temperature of the electrical equipment reaches a threshold, the increased temperature may lead to leakage, which will affect the entire discharge production line. This invention can also quickly lower the main support platform 201, allowing the electrical equipment on the main support platform 201 to contact the receiving component 301 set at the bottom through the flow port 2011. The receiving component 301 grounds the equipment, thereby quickly conducting away the current in case of leakage. Furthermore, because the main support platform 201 sinks at this time, the discharge process of the electrical equipment is directly disconnected, making the electrical equipment safer on the base.

[0037] When the battery under test 6 is discharging, pressure is applied to make it contact the battery discharger 5, thus ensuring the discharge effect. However, if the main support platform 201 needs to be lowered, this limiting will affect the isolation effect. Therefore, the electrical equipment in this embodiment includes the battery discharger 5 and the battery under test 6. A temperature sensor is provided on the auxiliary support platform 202 located on the battery discharger 5. A fixed motor 203 is provided in the connecting seat 102 for pressing the battery under test 6 against the battery discharger 5. The fixed motor 203 is electrically connected to the temperature sensor. Next, when the temperature sensor detects that the temperature is too high, the fixed motor 203 retracts, setting the fixed motor 203 of the battery under test 6 to a position away from the battery discharger 5, and making the fixed motor 203 electrically connected to the temperature sensor on the battery discharger 5. The temperature sensor will detect the temperature of the battery under test 6, and when it is known that the temperature of the battery under test 6 is too high, the fixed motor 203 will automatically release, so that the connection between the battery under test 6 and the battery discharger 5 is no longer tight, and then it will be directly disconnected as the main support platform 201 sinks. In this embodiment, the battery discharger 5 is a discharge plate.

[0038] The battery discharger 5 generates a lot of heat during use. Therefore, the auxiliary support platform 202 in this embodiment is provided with a heat sink 204 attached to the rear end of the battery discharger 5. The heat sink 204 is provided at the rear end of the battery discharger 5 to reduce its temperature and avoid affecting the temperature of the battery 6 to be tested. In this embodiment, the heat sink 204 is a heat sink fin structure formed by steel plates.

[0039] When the receiving component 301 is not overloaded during the discharge process, it needs to maintain a flow state between the flow port 2011 and the connecting seat 102 to avoid overheating of the bottom of the battery. Under normal conditions, it also needs to stably support the battery 6 to be tested. Therefore, the receiving component 301 in this embodiment includes a grounding seat 3011 fixed to the upper end of the lower base plate 103. The grounding seat 3011 is electrically connected to the temperature sensor. An elastic connecting seat 3012 is connected to the upper end of the grounding seat 3011. A grounding post 3013 located inside the elastic connecting seat 3012 is provided on the top of the grounding seat 3011. After the main support platform 201 moves down, it contacts the grounding post 3013. The grounding seat 3011 of the receiving component 301 is connected to the main support platform 201 through the elastic connecting seat 3012. The elastic connecting seat 3012 can support the main support platform 201. When the main support platform 201 needs to sink, it can be compressed to allow the battery 6 to be tested to contact the grounding post 3013.

[0040] The elastic connector 3012 extends and retracts according to the temperature state of the battery 6 under test. Specifically, the elastic connector 3012 includes a first electromagnet 121 connected to the grounding base 3011. A spring 122 is connected to the upper end of the first electromagnet 121, and a second electromagnet 123 is connected to the top of the spring 122. The top of the second electromagnet 123 is fixed to the lower end of the main support platform 201. When the first electromagnet 121 is energized, it pulls the second electromagnet 123 downward, causing the main support platform 201 to descend. When the battery 6 under test is too high, the grounding base 3011 is energized by the electrical signal of the temperature sensor, which in turn energizes the first electromagnet 121. The first electromagnet 121 attracts the second electromagnet 123, causing the second electromagnet 123 to compress the spring 122 while simultaneously pulling the main support platform 201 downward, thereby enabling the main support platform 201 to drive the battery 6 under test to sink.

[0041] In this embodiment, the flow guide 302 is a fan. When the flow port 2011 is connected to the inside of the connecting seat 102, the flow guide 302 draws out the heat generated during battery discharge from the bottom, thereby providing a base support solution that combines heat dissipation and grounding conductivity.

[0042] Existing base isolation components mostly adopt fixed installation methods, which cannot flexibly adjust the range and position of the isolation area according to actual testing needs. Therefore, this embodiment uses the movable lateral constraint 4. Under normal conditions, such as the discharge of large equipment with low current, the discharge process is safe and isolation is not required. However, when a small battery discharges rapidly, the main support platform 201 sinks due to the high temperature of the battery under test 6, which directly drives the movable lateral constraint 4 to rise. This causes the movable lateral constraint 4 to be lifted from the swing groove 2012 and isolated on both sides of the electrical equipment, thereby preventing the high temperature of the electrical equipment from affecting other discharge equipment in the vicinity. After the abnormal state is resolved, the movable lateral constraint 4 can be reset, thereby improving the flexibility of the entire base.

[0043] The movable lateral constraint 4 is flush with the entire upper support plate 101 under normal conditions. Therefore, two turnover cylinders are provided on the outer side of the swing groove 2012 in this embodiment. The movable lateral constraint 4 includes a rotating rod 401 rotatably installed in the turnover cylinder. An isolation plate 402 is sleeved on the outside of the rotating rod 401. The isolation plate 402 is connected to the main support platform 201 through a linkage 403. The isolation plate 402 is raised or placed flat as the main support platform 201 rises and falls. An external pipe 404 is connected to the lower end of the isolation plate 402. The rotating rod 401 of the movable lateral constraint 4 cooperates with the embedded turnover cylinder, and the isolation plate 402 is connected to the rotating rod 401 to achieve a rotatable effect. The isolation plate 402 is then linked to the main support platform 201 through the linkage 403, so that the isolation plate 402 and the main support platform 201 have a coordinated effect and their movements can be synchronized.

[0044] When isolating, the isolation plate 402 uses not only physical isolation but also chemical isolation. In this embodiment, the isolation plate 402 includes a rotating end 4021 sleeved on the rotating rod 401. An isolation plate surface 4022 is connected to the rotating end 4021. The end of the isolation plate surface 4022 facing the battery is provided with several positive ports 4023. The bottom end of the isolation plate surface 4022 is provided with several oblique ports 4024. The bottom surface of the isolation plate surface 4022 is connected to an external pipe 404. An external pipe 404 is provided at the lower end of the isolation plate 402 and is connected to an external fire extinguishing medium. Thus, after the isolation plate 402 is raised, the positive ports 4023 and oblique ports 4024 are aligned with the battery 6 to be tested. Then, the medium is introduced through the external pipe 404 to force cooling of the battery. Through chemical and physical isolation, the entire isolation process is made more stable.

[0045] In this embodiment, the linkage 403 consists of several steel cables. One end of each steel cable is welded to the main support platform 201, and the other end of each steel cable is wrapped around the isolation plate 402. The number of steel cables is set to be multiple, thereby ensuring the pulling effect of the entire isolation plate surface 4022.

[0046] Since the isolation plate 402 is dynamically set, the external pipe 404 in this embodiment includes a flexible hose portion 4041 that is connected to the bottom surface of the isolation plate 402. The flexible hose portion 4041 is connected to a straight pipe portion 4042 that leads to the outside of the connecting seat 102. The flexible hose portion 4041 can undergo adaptive deformation when the isolation plate 402 rotates.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
