Description

Technical Field

[0001] The invention relates to the technical field of energy storage cabinets, in particular to a UPS battery energy storage cabinet with a conveying function. Background Art

[0002] An energy storage cabinet is a device for storing and releasing electrical energy. It is mainly composed of a cabinet body and batteries installed inside. As an energy storage device that can use mobile power supply, it has a wide range of applications in the field of mobile power supply. However, when used in complex outdoor environments, energy storage cabinets are generally susceptible to various unstable factors. Under harsh conditions, the stability of heat dissipation varies greatly, affecting the stability of the energy storage cabinet.

[0003] The utility model patent with application number CN202122310215.1 discloses a UPS power supply with efficient heat dissipation function and good protection performance, including a first shell, and connecting rods are fixedly connected on all four sides of the bottom of the inner cavity of the first shell, and the top of the connecting rod is fixedly connected to the second shell, which solves the problem that the current UPS power supply has poor heat dissipation effect and poor protection performance, which makes the UPS power supply easily damaged by foreign objects.

[0004] However, it only uses a high-strength layer for hard protection, which cannot play a role in buffer protection, cannot provide effective protection for the internal structure when impacted, and cannot automatically disconnect the external power supply to achieve rapid power-off protection when internal damage occurs. In addition, most general UPS energy storage cabinets use lead-acid batteries, but lead-acid batteries are heavy, have poor energy storage effects, are not convenient for mobile use, and have a relatively short lifespan. The reason why UPS energy storage cabinets do not use lithium batteries is that the energy storage cabinets cannot provide effective protection for lithium batteries, and cannot control the explosion of lithium batteries when danger occurs, resulting in the inability to promote the use of lithium battery energy storage cabinets.

[0018] (III) Beneficial effects

[0019] The present invention provides a UPS battery energy storage cabinet with a conveying function. It has the following beneficial effects:

[0020] 1. The UPS battery energy storage cabinet with a conveying function has a battery pack located inside the protective device during mobile operation. When the battery and the protective box are laterally displaced internally due to impact and shaking, the elastic protective spring and the water inside the cooling chamber provide resistance to buffer the shaking force and impact force on the battery pack, thereby improving the protection effect on the inside of the battery. In addition, in the transportation state, the battery pack is disconnected from the wiring terminal to prevent short circuits, further improving the protection effect.

[0021] 2. In the process of power supply and use, the battery pack of the UPS battery energy storage cabinet with a conveying function is supported on the upper side of the L-shaped bracket. When the outer box is impacted by external force, the outer box is displaced and the battery pack remains relatively static, so that the battery pack will be offset inside the outer box. After the offset, the battery pack will push the clamping and positioning baffle to move outward, and the clamping and positioning baffle pushes the telescopic support frame to shrink. The telescopic support frame drives the support shaft frame to rotate through the cooperation of the tooth head and the meshing gear, and the support shaft frame drives the L-shaped bracket to rotate, so that the L-shaped bracket releases its supporting effect on the battery pack, causing the battery pack to fall. After the battery pack falls, the electrical connection between the conductive contact copper sheet seat and the battery pack is disconnected, thereby achieving the effect of power-off protection, preventing the battery pack from being unstable internally after being hit and then being used continuously to cause danger, and the battery pack can be quickly cooled down when it falls into the inside of the protective device to prevent danger.

[0022] 3. For the UPS battery energy storage cabinet with conveying function, when the battery is damaged and burns, the high-temperature flame generated will melt the top sealing rubber ring, and the cold water inside the cooling chamber will enter the inside of the protection box to immerse the battery pack for cooling. The cold water is continuously supplied through the water injection pipe, and the hot water is discharged through the drainage pipe after flowing in the cooling chamber in a counterclockwise direction for one circle, so as to achieve the effect of rapid cooling, so that the fire can be quickly controlled, and the burning battery fire is controlled inside the outer box to achieve rapid cooling, thereby improving the safety performance of use.

[0023] 4. The UPS battery energy storage cabinet with a conveying function discharges the high-pressure gas generated by internal combustion to the outside through a pressure relief valve to relieve the pressure, preventing the outer box from exploding due to high pressure. At the same time, the whistle installed at the end of the pressure relief valve is blown by the high-pressure airflow to sound an alarm for warning, which can enable the staff to quickly discover the fire and give an early warning, thereby preventing the fire from spreading and improving the safety of use.

[0024] 5. During normal use, the UPS battery energy storage cabinet with a conveying function adopts air cooling and water cooling to dissipate heat, and heat exchange is achieved inside the outer box, which reduces the impact of the external environment on the heat dissipation capacity of the equipment and improves the stability of heat dissipation.

[0036] Specifically, as attached Figure 6 As shown, the support spring 55 provides support force to the lower inclined plate 54 and the L-shaped bracket 53, so that the L-shaped bracket 53 can support the battery pack 8 on the upper side of the L-shaped bracket 53. At this time, the conductive contact copper sheet seat 12 is connected to the electrical contacts of the battery pack 8 under the support of the clamping positioning baffle 58, thereby realizing the power supply effect to the outside, and the inner sides of the L-shaped bracket 53 and the lower inclined plate 54 are inclined, so that when the battery pack 8 moves from bottom to top, it will push the L-shaped bracket 53 to deflect clockwise, so that the battery pack 8 can move to the upper side of the L-shaped bracket 53. After the battery pack 8 moves to the upper side of the L-shaped bracket 53, the L-shaped bracket 53 and the lower inclined plate 54 move to the bottom of the battery pack 8 for support under the push of the elastic force of the support spring 55.

[0037] In this embodiment, the protection device 6 includes a cooling box 61, a protection box 62, a heat spreader 63, an elastic protection spring 64, a top sealing connection rubber ring 65, a water injection pipe 66, a drainage pipe 67 and a bottom sealing connection rubber ring 68. The cooling box 61 is installed with the bottom inner wall of the outer box body 1, the protection box 62 is arranged inside the cooling box 61, the heat spreader 63 is installed on the inner wall surface of the protection box 62, the end of the elastic protection spring 64 is installed with the inner wall of the cooling box 61, the end of the elastic protection spring 64 away from the cooling box 61 is installed with the outer wall of the protection box 62, the top sealing connection rubber ring 65 is installed with the bottom of the protection box 68, and the bottom of the top sealing connection rubber ring 65 is installed with the protection box 61. The top of the protective box 62 is installed, the top of the top sealing connection rubber ring 65 is installed with the top inner wall of the cooling box 61, a gap is opened in the middle position of the bottom of the protective box 62 and the heat spreader 63, the bottom sealing connection rubber ring 68 is installed on the inner side of the bottom gap of the protective box 62, the inner side of the top sealing connection rubber ring 65 is rotatably installed through the sealing bearing and the outer wall of the support screw 71, the gap cavity between the cooling box 61 and the protective box 62 forms a cooling cavity, the water injection pipe 66 is installed with the outer wall of the outer box body 1, the drainage pipe 67 is installed with the outer wall of the outer box body 1, and the water injection pipe 66 and the drainage pipe 67 are both connected to the cooling cavity.

[0038] Specifically, as attached Figure 4 As shown, when the outer box 1 is impacted or shaken and offset during transportation, the cooling box 61 moves, and the battery pack 8 is offset on the inner side of the protection box 62 and the heat spreader 63. At this time, the elastic protection spring 64 and the water inside the cooling chamber provide resistance to buffer the shaking force and impact force on the battery pack 8, thereby improving the protection effect on the inside of the battery.

[0039] In this embodiment, the terminal 10 also includes a conductive copper sheet 11 and a conductive contact copper sheet seat 12. The conductive contact copper sheet seat 12 is installed on the surface of the clamping positioning baffle 58. The conductive contact copper sheet seat 12 is electrically connected to the battery pack 8 supported on the L-shaped bracket 53. The conductive copper sheet 11 is installed on the outer side of the conductive contact copper sheet seat 12. The end of the conductive copper sheet 11 with deformation ability away from the conductive contact copper sheet seat 12 is connected to the terminal 10.

[0040] Specifically, as attached Figure 6 As shown, the wiring contacts opened on the outer surface of the battery pack 8 are concavely arranged, and the width of the wiring contacts is greater than the width of the conductive contact copper sheet seat 12, so that when the battery pack 8 is offset in the front-to-back direction, the conductive contact copper sheet seat 12 and the wiring contacts can maintain contact, thereby maintaining the stability of power supply, and the battery pack 8 is electrically connected to the wiring terminal 10 through the cooperation of the conductive contact copper sheet seat 12 and the conductive copper sheet 11, and the power supply is realized by connecting the wiring terminal 10 to the external power supply wire.

[0041] In this embodiment, there are four support shaft frames 52 respectively arranged on the four inner side walls of the outer box body 1. Bevel gears are installed at the ends of the support shaft frames 52, and adjacent support shaft frames 52 are meshed through the bevel gears.

[0042] Specifically, as attached Figure 5 As shown, the four support shaft frames 52 are connected by bevel gears. When the support shaft frames 52 in one direction are deflected, the four support shaft frames 52 are deflected at the same time to drive the L-shaped bracket 53 to rotate, thereby releasing the support for the battery pack 8, causing the battery pack 8 to fall downward and enter the protective device 6 for protection.

[0043] In this embodiment, a tooth head is provided at the top of the extended end of the telescopic support frame 56 , and the tooth head meshes with the meshing gear 57 .

[0044] Specifically, as attached Figure 6 As shown, when the battery pack 8 is offset above the L-shaped bracket 53, it pushes the clamping positioning baffle 58 to compress the telescopic support frame 56. The telescopic support frame 56 drives the meshing gear 57 to rotate through the tooth head, and the meshing gear 57 drives the support shaft frame 52 to rotate. The support shaft frame 52 drives the L-shaped bracket 53 to rotate to release the support for the battery pack 8, causing the battery pack 8 to fall and enter a protective state.

[0045] In this embodiment, one-way valves are installed inside the water injection pipe 66 and the drainage pipe 67, and the flow directions of the two one-way valves are opposite.

[0046] Specifically, a one-way valve is provided to make the flow direction of water inside the cooling chamber more stable, thereby preventing the drain pipe 67 from backflowing due to excessive internal pressure.

[0047] In this embodiment, an elastic and retractable partition for separation is installed on the inner wall of the cooling box 61 and located between the water injection pipe 66 and the drainage pipe 67 .

[0048] Specifically, the annular cooling cavity is separated by an elastic telescopic plate, and cold water is injected into the cooling cavity through the water injection pipe 66. The cold water then flows counterclockwise along the cooling cavity, and finally flows to a position close to the drain pipe 67, and then is discharged through the drain pipe 67.

[0049] In this embodiment, the outer box body 1 and the connecting frame 2 at the bottom thereof are clamped and fixed by bolts, and a groove for stacking installation is formed on the top of the outer box body 1 and the outside of the sealing cover 4 for clamping the connecting frame 2. The outer wall of the sealing cover 4 is provided with screw holes, and the bottom and top ends of the support screw 71 are provided with clamping grooves for docking transmission, and the output end of the control motor 7 is clamped with the bottom end of the support screw 71.

[0050] Specifically, as attached Figure 1 and attached Figure 2 As shown, multiple outer boxes 1 can be stacked and used through the connecting frame 2, so that energy storage cabinets of different sizes can be set up for use according to the needs of use, thereby improving the scope of application. When the upper and lower parts are connected, the support screws 71 on the upper and lower sides will be plugged in to realize transmission, and the control motor 7 does not have the function of locking the support screw 71 in the non-working state, so that the support screw 71 will rotate under the downward pressure of the battery pack 8 and the positioning sleeve 72, and will not hinder the battery pack 8 from falling.

[0051] In this embodiment, a heat dissipation fan is installed at the bottom of the battery pack 8 to accelerate the air flow at the bottom.

[0052] Specifically, a corresponding cooling fan mounting groove and a guide groove for assisting gas flow are provided at the bottom of the battery pack 8. The battery pack 8 blows the gas between the bottom of the battery pack 8 and the top of the protection box 62 to flow in a circular manner. When the gas flows to the bottom of the battery pack 8, the battery pack 8 is cooled. After the gas flows to the top of the protection box 62, it contacts the heat spreader 63. Through the cooperation of the protection box 62 and the heat spreader 63, the heat is transferred to the cooling water in the cooling chamber to achieve cooling.

[0053] The working principle and use process of the present invention are as follows: in the moving and transporting state, the battery pack 8 is located on the inner side of the heat spreader 63. The lateral impact and shaking generated during the movement will be absorbed and buffered by the elastic protection spring 64 and the cooling water sealed inside the cooling chamber, thereby improving the protection effect of the battery pack 8 and improving the safety of transportation. When installing after the transportation is completed, the control motor 7 is controlled to drive the support screw 71 to rotate, and the support screw 71 drives the positioning sleeve 72 to move upward through the thread, and the positioning sleeve 72 drives the battery pack 8 to move upward. During the upward movement of the battery pack 8, the edge contacts the lower inclined plate 54, and the lower inclined plate 54 and the L-shaped bracket 53 are pushed by the inclined surface to drive the support shaft frame 52 to deflect, so that the battery pack 8 can smoothly pass through the L-shaped bracket 53 and The lower inclined plate 54 is blocked and moved to the top of the L-shaped bracket 53, and then the control motor 7 is controlled to stop rotating. The L-shaped bracket 53 and the lower inclined plate 54 are deflected inwardly under the push of the support spring 55, so that the L-shaped bracket 53 moves to the bottom of the battery pack 8 for support. At this time, the clamping positioning baffle 58 is tightly attached to the outside of the battery pack 8, and the battery pack 8 is connected to the external wire through the cooperation of the conductive contact copper sheet seat 12, the conductive copper sheet 11 and the terminal 10 to realize power supply. When in use, the cooling fan at the bottom of the battery pack 8 realizes air circulation and cooling inside, and cold water is supplied through the water injection pipe 66. The cold water flows inside the cooling chamber to dissipate heat and cool down. The hot water after heat dissipation is discharged through the drain pipe 67. When it is hit during use, the outer box body 1 The battery pack 8 is displaced and the battery pack 8 maintains a relatively static state, so that the battery pack 8 will be offset inside the outer box body 1. After the offset, the battery pack 8 will push the clamping and positioning baffle 58 to move outward, and the clamping and positioning baffle 58 pushes the telescopic support frame 56 to retract. The telescopic support frame 56 drives the support shaft frame 52 to rotate through the cooperation of the tooth head and the meshing gear 57, and the support shaft frame 52 drives the L-shaped bracket 53 to rotate, so that the L-shaped bracket 53 releases the supporting effect on the battery pack 8, so that the battery pack 8 falls. After the battery pack 8 falls, the electrical connection between the conductive contact copper sheet seat 12 and the battery pack 8 is disconnected, thereby achieving the effect of power-off protection, preventing the battery pack 8 from being internally unstable after being hit and then continuously used to cause danger, and When the battery pack 8 is damaged by a process or impact and spontaneously ignites, the high-temperature flame generated will melt the top sealing rubber ring 65, and the cold water inside the cooling chamber will enter the interior of the protective box 62 to immerse the battery pack 8 for cooling. The cold water is continuously supplied through the water injection pipe 66, and the hot water is discharged through the drain pipe 67 after flowing in the cooling chamber in a counterclockwise direction for one circle, so as to achieve the effect of rapid cooling, so that the fire can be quickly controlled. The burning battery fire is controlled inside the outer box 1 to achieve rapid cooling. At the same time, the high-pressure gas generated by the combustion inside is discharged to the outside through the pressure relief valve 9 to relieve the pressure, so as to prevent the outer box 1 from exploding due to the high pressure. At the same time, the whistle installed at the end of the pressure relief valve 9 is blown by the high-pressure airflow to sound an alarm for warning.It enables workers to quickly detect fires and issue early warnings, thus preventing the fire from spreading.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
