Description

Technical Field

[0001] The present invention belongs to the technical field of lithium batteries, and in particular is a mobile energy storage power station lithium battery pack. Background Art

[0002] Lithium battery is a kind of battery with excellent performance. It is widely used in various fields due to its many outstanding advantages. Lithium battery has high energy density and can store a large amount of electrical energy in a relatively small volume and weight. This feature makes it perform well in application scenarios with strict requirements on space and weight, such as portable electronic devices, electric vehicles, etc. At the same time, lithium battery also has a long cycle life. After multiple charges and discharges, it can still maintain high capacity and performance, reducing the cost of use and the trouble of frequent battery replacement. Among them, the existing mobile energy storage power stations also use lithium batteries. This is because lithium batteries can meet the needs of energy storage power stations for efficient and reliable energy storage and supply. Mobile energy storage power stations usually need to provide power support for various equipment and systems in different locations, so they have high requirements for battery performance and portability. The high energy density and light weight of lithium batteries enable energy storage power stations to be more conveniently transported and deployed during movement, providing rapid response to various emergency situations and temporary power needs.

[0003] Lithium batteries usually install lithium battery units in a shell. However, this traditional shell design has some obvious disadvantages in actual use. It needs to be locked with screws during disassembly and installation. This operation is cumbersome, takes a lot of time and effort, and has high technical requirements for operators. On the other hand, for lithium batteries on mobile energy storage power stations, different tools are needed to fix multiple lithium batteries in the energy storage power station during installation. This not only increases the complexity of installation, but also may cause the lithium battery to be installed loosely due to tool mismatch or improper use, affecting the performance and safety of the energy storage power station. In addition, lithium batteries rarely cause explosions due to internal current short circuits. Although the probability of this happening is low, once it happens, the consequences will be disastrous. When a short circuit occurs inside a lithium battery, the large amount of heat and gas generated instantly may cause explosions and fires, posing a serious threat to surrounding personnel and equipment. Moreover, since mobile energy storage power stations are usually used outdoors or in different places, once an explosion accident occurs, the difficulty of rescue will increase accordingly. Summary of the invention

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a mobile energy storage power station lithium battery pack, comprising an energy storage power station body and a battery pack, as well as a protective structure located outside the battery pack and a fire warning structure located inside the energy storage power station body, wherein a quick installation structure for installing the battery pack is provided on the back of the energy storage power station body; The protective structure includes protective side plates located on the left and right sides of the battery pack and sliding grooves opened on the inner walls of the protective side plates, and protective baffles slidably connected to the inner walls of the sliding grooves. A hidden groove is opened on the inner wall of the sliding groove, and a return spring is installed inside the hidden groove. An oblique movable block is fixedly installed on one side of the return spring close to the protective baffle. A sliding groove connected to the sliding groove and the hidden groove is opened on the outer wall of the protective side plate.

[0005] Preferably, an abutment block abutting against the oblique movable block is slidably connected to the inner wall of the slide groove, and an abutment plate is fixedly connected to the outside of the abutment block. A rotating block is rotatably connected above the slide groove, and the rotating block is locked and connected to the outside of the protective side plate by a nut. A protective top plate plug-connected between the two protective side plates is provided above the battery pack.

[0006] Preferably, the fire warning structure includes a smoke detector and a temperature detector installed on the top wall of the energy storage power station body, a spray pipe and a spray box installed on the top of the energy storage power station body, and a buzzer alarm is provided on the top of the spray box.

[0007] Preferably, a partition is provided in the middle of the energy storage power station body, and exhaust grooves distributed equidistantly are provided inside the partition.

[0008] Preferably, a purification box connected to the exhaust slot is installed at the back of the energy storage power station body, an explosion-proof fan is installed inside the purification box, and two layers of adsorption nets for adsorbing smoke and harmful substances are arranged in front of the explosion-proof fan.

[0009] Preferably, the quick installation structure includes a linearly distributed installation frame and two symmetrically distributed A buffer springs and B buffer springs fixedly installed on the inner wall of the installation frame, the other end of the A buffer spring is fixedly connected to the A clamping block, and the other end of the B buffer spring is fixedly connected to the B clamping block.

[0010] Preferably, the A clamping block is rotatably connected to the inner wall of the installation frame through a rotating rod, and a gap is provided in the middle of the A clamping block and the B clamping block.

[0011] Preferably, the protective baffle close to the A clamping block and the B clamping block is installed with a plug-in block plugged into the gap.

[0012] Preferably, the protective baffle close to the A clamping block and the B clamping block is installed with a plug-in block plugged into the gap.

[0013] Preferably, a placement plate is installed in the middle of the partition and below the battery pack.

[0014] Preferably, a protective bottom plate is provided at the bottom of the battery pack and is plug-connected to the two protective side plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention can achieve strict protection of the battery pack through the design of the protective structure, and provide reliable guarantee for the safe and stable operation of the battery. When performing the installation operation, the process is extremely simple and efficient. First, the two protective side plates are tightly pressed against the two sides of the battery pack, and then the two protective baffles are inserted into the pre-set sliding grooves. As the protective baffles slowly move downward, they will gradually contact the oblique movable block. The inclined surface of the protective baffle can convert the vertical movement of the protective baffle into a horizontal force. When the protective baffle contacts the oblique movable block, the reset spring begins to be stressed. During the stress process, the reset spring can store energy and release it at an appropriate time, bringing The movable oblique movable block and the abutment block abutting against it move, and the abutment block slides smoothly inside the slide groove. In order to further fix the protective structure, it can be locked by a nut. Finally, the protective top plate is covered on the top of the battery pack and plugged into the two protective side plates. The protective top plate is also made of high-strength material, which can effectively prevent external objects from impacting and squeezing the battery pack. The plug-in connection method makes the installation process faster and more convenient, and also ensures the firmness of the connection. Through such installation steps, the battery pack and the external shell can be quickly installed and disassembled, which not only improves the efficiency of installation and maintenance, but also reduces the difficulty and risk of operation.

[0016] The present invention provides a strong guarantee for the safe operation of the energy storage power station through the design of the fire warning structure. When a short circuit occurs in the battery pack inside the energy storage power station, a large amount of thick smoke will be quickly generated, and the temperature will gradually increase with the spread of the fire. At this critical moment, the smoke detector can keenly sense the change in smoke concentration in the air. When the smoke concentration exceeds the set threshold, the smoke detector will immediately send out an alarm signal through the buzzer alarm, while the temperature detector will continuously monitor the temperature changes of the surrounding environment. Once the temperature rises to a preset dangerous value, the temperature detector will also quickly The alarm mechanism is triggered. As the temperature continues to rise and the smoke density becomes higher and higher, the sprinkler pipe will quickly pump out the water in the sprinkler box and spray it evenly through the nozzle to prevent the fire from spreading further. At the same time, water can also play a role in cooling and extinguishing fires, buying precious time for subsequent rescue work. In addition, when a fire occurs, the explosion-proof fan will automatically start. The explosion-proof fan has a strong exhaust capacity and can quickly exhaust the thick smoke in the energy storage power station body. This can not only improve the visibility on the scene and provide a better working environment for rescue personnel, but also reduce the damage of thick smoke to equipment.

[0017] The present invention provides great convenience and efficiency for the installation of the battery pack in the energy storage power station body through the design of the quick installation structure. When the battery pack needs to be installed in the energy storage power station body, it is only necessary to accurately insert the plug-in block into the gap in the middle of the A clamping block and the B clamping block. In this process, due to the insertion of the plug-in block, the A buffer spring and the B buffer spring will be quickly stressed and deformed, and the A clamping block will rotate through the rotating rod. When the plug-in block is completely inserted in the middle of the A clamping block and the B clamping block, the A buffer spring and the B buffer spring will rebound in the elastic potential energy. Under the action, it will drive the A clamping block and the B clamping block to reset quickly. This resetting action can tightly clamp the plug-in block, thereby firmly fixing the battery pack. In addition, during the entire installation process, the plug-in position is precisely designed. It is only necessary to place the battery pack on top of the placement plate to ensure that the plug-in block is accurately aligned with the gap between the A clamping block and the B clamping block, thereby achieving the significant effect of quickly installing the battery pack inside the energy storage power station body, which not only greatly saves installation time and improves work efficiency, but also reduces the complexity and difficulty of operation during the installation process.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides a mobile energy storage power station lithium battery pack, including an energy storage power station body 1 and a battery pack 2, as well as a protective structure 3 located outside the battery pack 2 and a fire warning structure 4 located inside the energy storage power station body 1, and a quick installation structure 5 for installing the battery pack 2 is provided on the back of the energy storage power station body 1; The protective structure 3 includes protective side plates 31 located on the left and right sides of the battery pack 2, sliding grooves 32 opened on the inner walls of the protective side plates 31, and protective baffles 33 slidably connected to the inner walls of the sliding grooves 32. A hidden groove 34 is opened on the inner wall of the sliding groove 32, and a return spring 35 is installed inside the hidden groove 34. An oblique movable block 36 is fixedly installed on one side of the return spring 35 close to the protective baffle 33. A sliding groove 37 connected to the sliding groove 32 and the hidden groove 34 is opened on the outer wall of the protective side plate 31.

[0022] Through the design of the protective structure 3, strict protection of the battery pack 2 can be achieved, providing reliable guarantee for the safe and stable operation of the battery. During the installation operation, first, the two protective side panels 31 are tightly pressed against the two sides of the battery pack 2. The two protective side panels 31 are usually made of high-strength materials, such as aluminum alloy or carbon fiber composite materials, and have good compression and impact resistance. The surface of the protective side panels 31 is specially treated and sprayed with an anti-corrosion coating to improve its corrosion resistance and wear resistance. Then, the two protective baffles 33 are inserted into the pre-set sliding grooves 32. As the protective baffles 33 slowly move downward, they will gradually contact the oblique movable block 36. The inclined surface can convert the vertical movement of the protective baffle 33 into a horizontal force. When the protective baffle 33 contacts the oblique movable block 36, the reset spring 35 begins to be stressed. The reset spring 35 is made of highly elastic steel and has It has good elastic recovery performance. During the force-bearing process, the reset spring 35 can store energy and release it at an appropriate time, driving the oblique movable block 36 and the abutment block 371 abutting therewith to move. The abutment block 371 slides smoothly inside the slide groove 37 to ensure the stability and reliability of the entire structure. In order to further fix the protective structure 3, it can be locked by a nut. The selection of nuts should be based on actual needs to ensure that they have sufficient strength and tightening force. Finally, the protective top plate 39 is covered on top of the battery pack 2 and plugged in between the two protective side plates 31. The protective top plate 39 is also made of high-strength material, which can effectively prevent external objects from impacting and squeezing the battery pack 2. The plug-in connection method makes the installation process faster and more convenient, while also ensuring the firmness of the connection. Through such installation steps, the battery pack 2 and the external shell can be quickly installed and disassembled.

[0023] like Figures 1 to 8 As shown, an abutment block 371 abutting against the oblique movable block 36 is slidably connected to the inner wall of the slide groove 37, and an abutment plate is fixedly connected to the outside of the abutment block 371, a rotating block 38 is rotatably connected to the top of the slide groove 37, and the rotating block 38 is locked and connected to the outside of the protective side plate 31 by a nut, and a protective top plate 39 plug-connected between the two protective side plates 31 is arranged above the battery pack 2, and the fire warning structure 4 includes a smoke detector 41 and a temperature detector 42 installed on the inner top wall of the energy storage power station body 1, as well as a spray pipe 43 and a spray box 44 installed on the top of the energy storage power station body 1, and a buzzer alarm 45 is arranged on the top of the spray box 44, and a partition 11 is arranged in the middle of the energy storage power station body 1, and exhaust grooves distributed equidistantly are opened inside the partition 11.

[0024] The well-designed fire warning structure 4 provides a strong guarantee for the safe operation of the energy storage power station body 1. When the battery pack 2 inside the energy storage power station body 1 short-circuits and catches fire, it can respond in the first time. The short-circuit and fire of the battery pack 2 will quickly produce a large amount of thick smoke, which will not only affect the line of sight, but also may contain toxic and harmful substances, posing a serious threat to personnel and equipment. At the same time, the temperature will gradually increase with the spread of the fire. At this critical moment, the smoke detector 41 and the temperature detector 42 play a vital role. The smoke detector 41 can keenly sense the changes in the smoke concentration in the air. When the smoke concentration exceeds the set threshold, the smoke detector 41 will immediately send out an alarm signal, and the temperature detector 42 will continue to monitor the temperature changes of the surrounding environment. Once the temperature rises to the preset dangerous value, the temperature detector 42 will also quickly trigger the alarm mechanism. As the temperature continues to rise and the smoke density becomes higher and higher, the sprinkler pipe 43 begins to play a role. The sprinkler pipe 43 is connected to the sprinkler box 44 to quickly sprinkle the sprinkler box The water in 44 is extracted and sprayed evenly through the nozzle. The spraying of water can effectively reduce the temperature around the battery pack 2 and prevent the further spread of the fire. At the same time, water can also play a role in cooling and extinguishing the fire, buying precious time for subsequent rescue work. In addition, when a fire occurs, the explosion-proof fan 47 will also start automatically. The explosion-proof fan 47 has a strong exhaust capacity and can quickly exhaust the thick smoke in the energy storage power station body 1. This can not only improve the visibility on the scene and provide a better working environment for rescue personnel, but also reduce the damage of thick smoke to equipment. At the same time, exhausting thick smoke also helps to reduce the degree of harm caused by the fire and prevent the smoke from spreading to other areas and causing greater losses. In short, through the design of the fire warning structure 4, the smoke detector 41, the temperature detector 42, the spray pipe 43 and the explosion-proof fan 47 and other components work together, and can quickly respond when the battery pack 2 inside the energy storage power station body 1 short-circuit catches fire, and effectively cool down, extinguish the fire and exhaust the smoke, so as to maximize the safety of personnel and equipment.

[0025] like Figures 1 to 8 As shown, a purification box 46 connected to the exhaust slot is installed at the back of the energy storage power station body 1, an explosion-proof fan 47 is installed inside the purification box 46, and a two-layer adsorption net 48 for adsorbing smoke and harmful substances is arranged in front of the explosion-proof fan 47. The quick installation structure 5 includes a linearly distributed installation frame 51 and two symmetrically distributed A buffer springs 52 and B buffer springs 53 fixedly installed on the inner wall of the installation frame 51, the other end of the A buffer spring 52 is fixedly connected to the A clamping block 54, and the other end of the B buffer spring 53 is fixedly connected to the B clamping block 55.

[0026] The design of the quick installation structure 5 provides great convenience and efficiency for the installation of the battery pack 2 in the energy storage power station body 1. When the battery pack 2 needs to be installed in the energy storage power station body 1, it is only necessary to accurately insert the plug-in block 57 into the gap in the middle of the A clamping block 54 and the B clamping block 55. In this process, due to the insertion of the plug-in block 57, the A buffer spring 52 and the B buffer spring 53 will be quickly deformed by force, and the A clamping block 54 will rotate through the rotating rod 56. The design of the rotating rod 56 enables the A clamping block 54 to rotate flexibly to adapt to the insertion action of the plug-in block 57. The material of the rotating rod 56 usually has high strength and good wear resistance, ensuring that stable performance can be maintained during multiple uses. When the plug-in block 57 is fully inserted into the A clamping block 54 and the B clamping block 55, the A buffer spring 52 and the B buffer spring 53 will drive the A clamping block 54 and the B clamping block 55 to quickly reset under the rebound effect of the elastic potential energy. This resetting action can tightly clamp the plug-in block 57, so as to achieve a firm fixation of the battery pack 2. In addition, during the entire installation process, the plug-in position is precisely designed. It is only necessary to place the battery pack 2 on the top of the placement plate 12 to ensure that the plug-in block 57 is accurately aligned with the gap between the A clamping block 54 and the B clamping block 55. The placement plate 12 can ensure that the battery pack 2 maintains a stable position during the installation process to avoid sliding or shaking, thereby achieving a significant effect of quickly installing the battery pack 2 inside the energy storage power station body 1, which not only greatly saves installation time and improves work efficiency, but also reduces the complexity and difficulty of operation during the installation process.

[0027] like Figures 1 to 8 As shown, the A clamping block 54 is rotatably connected to the inner wall of the mounting frame 51 through a rotating rod 56, and a gap is provided in the middle of the A clamping block 54 and the B clamping block 55, wherein the protective baffle 33 close to the A clamping block 54 and the B clamping block 55 is installed with a plug-in block 57 plugged into the gap, a placement plate 12 is installed in the middle of the partition 11 and below the battery pack 2, and a protective bottom plate 311 plug-in connected to the two protective side plates 31 is provided at the bottom of the battery pack 2.

[0028] The design of the quick installation structure 5 provides great convenience and efficiency for the installation of the battery pack 2 in the energy storage power station body 1. When the battery pack 2 needs to be installed in the energy storage power station body 1, it is only necessary to accurately insert the plug-in block 57 into the gap between the A clamping block 54 and the B clamping block 55. In this process, due to the insertion of the plug-in block 57, the A buffer spring 52 and the B buffer spring 53 will be quickly deformed by force, and the A clamping block 54 will rotate through the rotating rod 56. When the plug-in block 57 is fully inserted into the middle of the A clamping block 54 and the B clamping block 55, the A buffer spring 52 and the B buffer spring 53 are elastically deformed. Under the rebound effect of potential energy, the A clamping block 54 and the B clamping block 55 will be quickly reset. This reset action can tightly clamp the plug-in block 57, thereby firmly fixing the battery pack 2. In addition, during the entire installation process, the plug-in position is precisely designed. It is only necessary to place the battery pack 2 above the placement plate 12 to ensure that the plug-in block 57 is accurately aligned with the gap between the A clamping block 54 and the B clamping block 55, thereby achieving a significant effect of quickly installing the battery pack 2 inside the energy storage power station body 1, which not only greatly saves installation time and improves work efficiency, but also reduces the complexity and difficulty of operation during the installation process.

[0029] The working principle and use process of the present invention: First, install the protective structure 3, first place the two protective side panels 31 close to the two sides of the battery pack 2, and then insert the protective baffle 33 into the sliding groove 32 on the inner wall of the protective side panel 31. As the protective baffle 33 moves downward, it gradually contacts the oblique movable block 36 in the hidden groove 34. The inclined surface of the oblique movable block 36 converts the vertical movement of the protective baffle 33 into a horizontal force, so that the reset spring 35 is stressed, driving the oblique movable block 36 and the abutting block 371 abutting therewith to slide inside the sliding groove 37. When the abutting block 371 slides to a suitable position, it is locked and connected to the protective side panel through the rotating block 38 and the nut. 31 outside, further fix the protection structure 3, and finally cover the top plate 39 on the battery pack 2, and connect it with the two protection side plates 31 to effectively prevent external objects from hitting and squeezing the battery pack 2, and then install the battery pack 2, and place the battery pack 2 on the placement plate 12 inside the energy storage power station body 1 to ensure the accurate position. At this time, the plug-in block 57 is aligned with the gap in the middle of the A clamping block 54 and the B clamping block 55, and then the plug-in block 57 is plugged into the gap in the middle of the A clamping block 54 and the B clamping block 55. During the plug-in process, the A buffer spring 52 and the B buffer spring 53 are deformed by force. At the same time, the A clamping block 54 rotates through the rotating rod 56 to provide space for the insertion of the plug-in block 57. When the plug-in block 57 is fully plugged in, the A buffer spring 52 and the B buffer spring 53 drive the A clamping block 54 and the B clamping block 55 to reset under the rebound effect of the elastic potential energy, tightly clamp the plug-in block 57, and firmly fix the battery pack 2. Finally, when the battery pack 2 inside the energy storage power station body 1 short-circuit catches fire, the smoke detector 41 and the temperature detector 42 detect the abnormality at the first time. The smoke detector 41 sensitively senses the change in smoke concentration in the air and emits a warning when the smoke concentration exceeds the set threshold. Alarm signal, the temperature detector 42 continuously monitors the temperature changes of the surrounding environment. Once the temperature rises to the preset dangerous value, the alarm mechanism is quickly triggered. As the temperature continues to rise and the smoke density becomes higher and higher, the spray pipe 43 draws water from the spray box 44 for spraying, cooling the internal battery pack 2 to prevent the fire from spreading further. At the same time, the explosion-proof fan 47 automatically starts to discharge the thick smoke in the energy storage power station body 1 through the purification box 46 connected to the exhaust slot. The two layers of adsorption net 48 in the purification box 46 absorb smoke and harmful substances, providing a better working environment for rescue personnel and reducing the degree of fire hazards.
