[0048] The present invention provides the following embodiments:
[0049] Example 1
[0050] This invention provides an integrated box-type energy storage lithium battery, such as... Figure 1-4 As shown, the device includes a container 1, a photovoltaic panel 100, and a lithium battery body 2. The photovoltaic panel 100 is installed on the container 1 via a photovoltaic storage assembly 101, and the lithium battery body 2 is installed inside the container 1. The photovoltaic panel 100 and the lithium battery body 2 are electrically connected.
[0051] The working principle and beneficial effects of the above technical solution are as follows: When the integrated box-type energy storage lithium battery is in use, the photovoltaic panel 100 converts solar energy into electrical energy and stores it in the lithium battery body 2. When the integrated box-type energy storage lithium battery is being moved or is not in use, the photovoltaic storage component 101 stores the photovoltaic panel 100 into the container 1, thereby reducing the probability of damage to the photovoltaic panel 100, extending the overall service life of the box-type energy storage lithium battery, and reducing maintenance costs. The lithium battery body 2 is installed in the container 1, resulting in a high degree of system integration, strong environmental adaptability, and reduced workload for on-site installation, commissioning, and subsequent maintenance. This invention solves the technical problem that in lithium battery energy storage systems with photovoltaic panels fixedly connected to the box via columns, the photovoltaic panels cannot be stored during transportation or when they are not in use, which greatly increases the probability of damage to the photovoltaic panels, thereby shortening the overall service life of the box-type energy storage lithium battery and increasing maintenance costs.
[0052] Example 2
[0053] Based on the above embodiment 1, the photovoltaic data storage module 101 includes:
[0054] The lifting platform 1010 is connected to the container 1 via an electric telescopic component 1011;
[0055] L-shaped plate 1012 is slidably connected to the lifting plate 1010. The end of L-shaped plate 1012 away from the lifting plate 1010 is located in the storage cavity 1013 of container 1. L-shaped plate 1012 is provided with a first sliding drive component, which is used to drive L-shaped plate 1012 to slide along the lifting plate 1010. Container 1 is provided with a photovoltaic panel placement opening 1019, which communicates with the storage cavity 1013.
[0056] Two sets of linkage assemblies are provided, each including a first linkage 1014 and a second linkage 1015. One end of the first linkage 1014 is hinged to the L-shaped plate 1012, and the other end is hinged to the photovoltaic panel 100. One end of the second linkage 1015 is hinged to the middle of the first linkage 1014, and the other end is hinged to a storage slider 1016. The storage slider 1016 is slidably connected in the storage slider groove 1017 of the L-shaped plate 1012. A buffer elastic element 1018 is fixedly connected between the storage slider groove 1017 and the storage slider 1016. A second sliding drive element is provided on the storage slider 1016, which is used to drive the storage slider 1016 to slide along the storage slider groove 1017.
[0057] The container 1 is equipped with a battery control cabinet 3, which is electrically connected to the photovoltaic panel 100 and the lithium battery body 2. The lithium battery body 2 has a total capacity of 5018kWh and consists of 14 battery clusters. The battery clusters are connected to the DC side of the energy storage converter after being combined in the battery control cabinet 3.
[0058] The container 1 is equipped with a temperature control system, which is used to regulate the temperature inside the container 1. The temperature control system includes an outdoor air conditioning unit 300 and an indoor air conditioning unit 301, which are connected by a pipe 302.
[0059] The container 1 is equipped with an automatic fire protection system, which includes a smoke sensor 303, a fire pipe 304 and a fire sprinkler 305.

The fire sprinkler 305 is installed on the fire pipe 304 and the fire pipe 304 is connected to the external fire extinguishing gas source.
[0060] The extinguishing gas source includes either carbon dioxide or haloalkanes;
[0061] A buffer layer 306 is provided between the lithium battery body 2 and the inner wall of the container 1.
[0062] The working principle and beneficial effects of the above technical solution are as follows: When storing the photovoltaic panel 100, the second sliding drive component drives the storage slider 1016 to slide along the storage slider groove 1017, which compresses the buffer elastic component 1018. The sliding of the storage slider 1016 drives the second connecting rod 1015 and the first connecting rod 1014 to move, thereby allowing the photovoltaic panel 100 to be stored in the photovoltaic panel placement opening 1019. Then, the electric telescopic component 1011 extends and drives the lifting plate 1010 to move downward. After that, the first sliding drive component drives the L-shaped plate 1012 to slide along the lifting plate 1010, causing the L-shaped plate 1012 to move towards the storage cavity 1013. Finally, the photovoltaic panel 100 is stored in the storage cavity 1013.
[0063] When the photovoltaic panel 100 is put into use, the photovoltaic storage component 101 drives the photovoltaic panel 100 to extend out of the photovoltaic panel placement opening 1019. Then, the second sliding drive component corresponding to the two sets of linkage components drives the two storage sliders 1016 to slide along the storage slider groove 1017 for different distances, thereby making the photovoltaic panel 100 tilt at a certain angle and increasing the photoelectric conversion efficiency.
[0064] When the smoke sensor 303 detects that the smoke inside container 1 exceeds the standard, it controls the valve of the fire extinguishing pipe 304 to open, and the external fire extinguishing gas source is sprayed out through the fire sprinkler head 305 to extinguish the fire. A buffer layer 306 is provided between the inner walls of container 1. The design of the buffer layer 306 reduces the damage to the battery body 2 caused by the collision between the battery body 2 and container 1, and increases its service life.

A second bevel gear 5036 is connected to the linkage shaft 5035 by a sliding key. A first driving member is provided on the sliding key corresponding to the second bevel gear 5036.

An extension hole 5053 is opened on the heat conduction shell 500.
[0071] The working principle and beneficial effects of the above technical solution are as follows: When the temperature control system of the integrated box-type energy storage lithium battery malfunctions or its temperature control system is not strong enough, a pre-installed heat dissipation component 5 can be used to dissipate heat from the lithium battery body 2, including two heat dissipation methods:
[0072] Method 1: When in use, manually press button 5001 to make the locking block 5002 slide along the first slide groove 5003. During the sliding of the locking block 5002 along the first slide groove 5003, the first wedge block 5009 acts on the second wedge block 5031, pushing the second wedge block 5031 to move upward, so that the two flip covers 5021 rotate around the cover mounting rod 5020, so that a gap is created between the flip covers 5021 and the heat-conducting shell 500. When the flip covers 5021 are rotated to the position, manually push the stop block 5005 downward, so that the locking block 5002 will not reset under the action of the first elastic element 5007, thus keeping the flip covers 5021 in the current state (a gap is created between the flip covers 5021 and the heat-conducting shell 500). The existence of the gap increases the airflow between the inside and outside of the container 1, so that the heat generated by the lithium battery body 2 can be quickly dissipated into the air.
[0073] Method 2: When in use, the third driving component drives the sliding block 505 to slide along the second sliding groove 5051, causing the heat transfer metal block 5050 to be in close contact with the lithium battery body 2, and the heat on the lithium battery body 2 is transferred to the heat conduction shell 500 through the lithium battery body 2.
[0074] The first driving member drives the second bevel gear 5036 to slide along the linkage shaft 5035, so that the second bevel gear 5036 meshes with the first bevel gear 5034, and then the second driving member drives the meshing gear 5033 to reciprocate.
[0075] The reciprocating rotation of the meshing gear 5033 drives the Z-shaped rack 5032 to move up and down reciprocally. The reciprocating movement of the Z-shaped rack 5032 causes the two flip covers 5021 to rotate around the cover mounting rod 5020, resulting in a gap between the flip covers 5021 and the heat-conducting shell 500, and the gap is generated repeatedly.
[0076] The reciprocating rotation of meshing gear 5033 drives the first bevel gear 5034 to rotate, which in turn drives the second bevel gear 5036 to rotate, which in turn drives the linkage shaft 5035 to rotate, which in turn drives the third bevel gear 5040 to rotate, which in turn drives the fourth bevel gear 5042 to rotate, which in turn drives the rotating bent rod 5041 to rotate. 041 reciprocates, driving the actuator piston 5046 to move back and forth. The reciprocating movement of the actuator piston 5046 discharges the air in the sliding cylinder 5044 into the heat-conducting housing 500, driving the air flow and accelerating the air flow between the inside and outside of the heat-conducting housing 500, thus accelerating the heat dissipation of the lithium battery body 2. The hot air flows out of the heat-conducting housing 500 through the gap created between the flip cover 5021 and the heat-conducting housing 500. When the actuator piston 5046 squeezes the air outward, the gap between the flip cover 5021 and the heat-conducting housing 500 is just opened.
[0077] The design of the pre-heat dissipation component 5 avoids the technical problem that the lithium battery body 2 cannot dissipate heat in time during long-term operation when the temperature control system of the integrated box-type energy storage lithium battery fails, which greatly affects its stability and service life.

[0084] The controller is electrically connected to the first temperature sensor, the humidity sensor, and the moisture-proof unit. The controller controls the triggering of the moisture-proof unit based on the first temperature sensor and the humidity sensor, including the following steps one and two:
[0085] Step 1: Based on the first temperature sensor, humidity sensor, and formula (1), calculate the actual humidity alarm trigger coefficient of the lithium battery body 2:
[0086]
[0087] in, T1 is the actual humidity alarm trigger coefficient of the lithium battery body 2, T0 is the detection value of the first temperature sensor, T0 is the temperature of the environment where the lithium battery body 2 is located, e is a natural number with a value of 2.72, ln is the natural logarithm with e as the base, C1 is the detection value of the humidity sensor, and C0 is the baseline maximum humidity of the lithium battery body 2 during normal operation.
[0088] Step 2: The controller compares the actual humidity alarm trigger coefficient of the lithium battery body 2 with the preset humidity alarm trigger coefficient of the lithium battery body 2. If the actual humidity alarm trigger coefficient of the lithium battery body 2 is greater than the preset humidity alarm trigger coefficient of the lithium battery body 2, the moisture-proof unit is triggered and starts working.
[0089] The moisture-proof unit includes:
[0090] The second temperature sensor is located at the air outlet of the moisture-proof unit and is used to detect the temperature of the hot air at the air outlet of the moisture-proof unit.
[0091] A timer is installed on the moisture-proof unit to detect the working time of the moisture-proof unit;
[0092] A flow rate sensor is installed at the air outlet of the moisture-proof unit to detect the flow rate of hot air at the air outlet of the moisture-proof unit.
[0093] The controller, alarm, is electrically connected to a second temperature sensor, a timer, a flow rate sensor, and the alarm. The controller controls the alarm to sound based on the second temperature sensor, the timer, and the flow rate sensor, including steps three and four:
[0094] Step 3: Based on the second temperature sensor, timer, flow rate sensor, and formula (2), calculate the actual effectiveness coefficient of the moisture-proof unit:
[0095]
[0096] in, This represents the actual effectiveness coefficient of the moisture-proof unit.

This represents the actual moisture alarm trigger coefficient for the lithium battery body 2. The actual mass of water to be evaporated in the lithium battery body 2;
[0097] Step 4: The controller compares the actual operating coefficient of the moisture-proof unit with the preset operating coefficient of the moisture-proof unit. If the actual operating coefficient of the moisture-proof unit is less than the preset operating coefficient, the alarm will sound, indicating that the moisture-proof unit is faulty.
[0098] The working principle and beneficial effects of the above technical solution are as follows: The design of the lithium battery moisture-proof system avoids the situation where the lithium battery body 2 cannot operate normally due to the humidity of the environment when it is in a humid environment. It expands the application environment of the lithium battery body 2 and increases the adaptability of the lithium battery body 2. Based on the temperature and humidity of the lithium battery body 2, the actual humidity alarm trigger coefficient of the lithium battery body 2 is calculated. Then the controller compares the actual humidity alarm trigger coefficient of the lithium battery body 2 with the preset humidity alarm trigger coefficient of the lithium battery body 2. If the actual humidity alarm trigger coefficient of the lithium battery body 2 is greater than the preset humidity alarm trigger coefficient of the lithium battery body 2, the moisture-proof unit is triggered and starts to work. Then, based on the second temperature sensor, timer, flow rate sensor and formula (2), the actual action coefficient of the moisture-proof unit is calculated. Finally, the controller compares the actual action coefficient of the moisture-proof unit with the preset action coefficient of the moisture-proof unit. If the actual action coefficient of the moisture-proof unit is less than the preset action coefficient of the moisture-proof unit, the alarm is triggered, indicating that the moisture-proof unit is faulty, and reminding the staff to carry out timely maintenance of the lithium battery moisture-proof system.
