Description

Technical Field

[0001] The utility model relates to a frostbite prevention system for transporting and repairing energy storage equipment in low-temperature areas, and relates to the field of electrochemical energy storage. Background Art

[0002] Currently, electrochemical energy storage products are mostly presented in the form of containers or outdoor cabinets. To ensure that the batteries installed inside operate within a constant temperature range, containers and outdoor cabinets are generally equipped with a certain thickness of insulation layer. At the same time, air conditioners or chillers are also installed to cool the batteries when the temperature is high and heat them when the temperature is low to ensure a constant temperature.

[0003] The constant temperature measures used in energy storage systems generally do not cause major problems when they are operating normally. However, in cold regions, the energy storage system cannot be powered on during the transportation of energy storage products or during the system installation phase, and its air conditioning cannot generate heat. If it is in a low-temperature environment for a long time, even containers and outdoor cabinets with insulation layers will reach temperature equilibrium with the external environment, and the battery will be frozen below -20°C. During shutdowns for maintenance, the system may not be powered on and the heating equipment may not work properly. This is especially true for some purely off-grid systems that do not have grid power. Once shut down, the equipment will be in low temperatures. If timely measures are not taken, the battery will soon be frozen and cause losses. At the same time, it will also cause freezing of low-temperature-sensitive equipment such as control panels. Utility Model Content

[0004] The purpose of the utility model is to address the defects or shortcomings in the existing technology and provide a frostbite prevention system for the transportation and maintenance of energy storage equipment in low-temperature areas. By arranging air inlets and air outlets on the loading cabinet of the energy storage equipment and cooperating with the heating blower arranged on the energy storage equipment transportation vehicle to perform convection constant temperature, it is ensured that the energy storage equipment will not be affected by the low temperature and frostbite during transportation. In addition, a high-power heating blower is equipped in the maintenance area to connect multiple energy storage equipment through bellows for centralized heating, ensuring that the energy storage equipment is not affected by the low temperature during shutdown and maintenance, thereby effectively providing constant temperature protection for the energy storage equipment and preventing damage due to environmental influences during transportation or shutdown and maintenance in low-temperature areas.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a system for transporting, repairing and preventing frostbite of energy storage equipment in low-temperature areas, which includes a cabinet 1, a first heating blower 2, a second heating blower 3, and a transport vehicle 5. The first heating blower 2 is arranged on the transport vehicle 5, and the second heating blower 3 is arranged in the maintenance area 9. The cabinet 1 is provided with an air inlet 11 at the lower part of one end and an air outlet 12 at the upper part of the other end. The first heating blower 2 is provided with a first bellows 4 that matches the air inlet 11, and the second heating blower 3 is provided with a second bellows 6 that matches the air inlet 11.

[0006] Furthermore, a one-way sealing plate is provided inside the air inlet 11 , and a one-way sealing plate is provided outside the air outlet 12 .

[0007] Furthermore, the outer layers of the first corrugated pipe 4 and the second corrugated pipe 6 are provided with a thermal insulation cotton layer 7 .

[0008] Furthermore, the second corrugated pipe 6 includes a long air duct and a plurality of bent short pipes connected thereto. The long air duct has a short pipe connected to the second heating blower 2 , and the bent short pipe matches the air inlet 11 .

[0009] Furthermore, the transport vehicle 5 is also provided with a diesel generator 8 , which is electrically connected to the first heating blower 2 .

[0010] The working principle of the present invention is as follows: during the transportation of the energy storage equipment, the diesel generator 8 generates electricity to drive the first heating blower 2 to blow out hot air. The hot air enters the cabinet 1 through the first bellows 4, and the colder air in the cabinet 1 is discharged from the air outlet 11. The air in the cabinet 1 remains in a circulating state, which effectively prevents the battery cell temperature from being too low during transportation and causing battery damage. When the energy storage equipment is transported to the construction site, the diesel generator 8 and the first heating blower 2 are placed together on one side until the construction is completed to ensure that the battery cells remain at a constant temperature during the construction process. After the construction is completed, the diesel generator 8 and the first heating blower 2 are moved back to the transport vehicle 5 and fixed. If there is a temporary grid power supply at the construction site, the temporary grid power supply is used to supply the first heating blower 2. The fan 2 is powered to ensure that hot air is continuously supplied to the cabinet 1 for 24 hours; and when the energy storage equipment needs to be shut down for maintenance, after being transported to the maintenance area 9, the second bellows 6 is connected to the air inlet 11 on the cabinet 1, and the second heating blower 3 is started to provide hot air for the cabinet 1. At this time, the second heating blower 3 can provide hot air to multiple cabinets 1 at the same time. The second heating blower 3 provides electricity through the grid power supply of the maintenance area 9, or provides electricity through photovoltaic equipment, or provides electricity through wind power generation equipment. By adopting a constant temperature method of on-board heating and unified heating in place, it can effectively provide continuous heat for the energy storage equipment to prevent the battery from being damaged by frostbite due to low temperature in cold and low-temperature areas, thereby ensuring the normal and effective transportation and storage of the energy storage equipment.

[0018] See Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: a system for transporting, repairing and preventing frostbite of energy storage equipment in low temperature areas, which includes a cabinet 1, a first heating blower 2, a second heating blower 3, and a transport vehicle 5. The first heating blower 2 is arranged on the transport vehicle 5, and the second heating blower 3 is arranged in the maintenance area 9. The cabinet 1 is provided with an air inlet 11 at the lower part of one end and an air outlet 12 at the upper part of the other end. The first heating blower 2 is provided with a first bellows 4 that matches the air inlet 11, and the second heating blower 3 is provided with a second bellows 6 that matches the air inlet 11. In this embodiment, three scenarios of energy storage equipment are provided. Antifreeze methods include an antifreeze solution during transportation on a vehicle. A first heating blower is installed on the transport vehicle, and the first heating blower is connected to the cabinet through a first bellows to blow hot air to maintain a constant temperature for the energy storage equipment. It should be noted that the cabinet can be a container or an outdoor cabinet, which can be selected according to actual production needs. However, air inlets and air outlets must be provided on the cabinet. The air inlet is provided at the lower part of one end of the cabinet, that is, the air inlet is provided on the lower side of the battery compartment, and the air outlet is provided above the battery compartment and the electrical compartment on the opposite side of the air inlet. Hot air blown in from the bottom can be more evenly diffused in the cabinet, and convection constant temperature can be more effectively achieved.

[0019] Second, to prevent freezing during the installation of energy storage equipment, if there is no power supply at the installation site, the original vehicle power supply equipment will be used to provide power and heating for the transported energy storage equipment. If there is power supply at the installation site, such as photovoltaic or grid power, the power energy at the site will be directly used for power and heating to maintain a constant temperature for the energy storage equipment.

[0020] Third, if the energy storage equipment fails and needs to be repaired, the equipment is unloaded to the maintenance area. The maintenance area is provided with a second heating blower, and the second heating blower is a high-power device with a second bellows provided thereon. The second bellows can be connected to multiple cabinets. When the energy storage equipment to be repaired is placed, the second heating blower is turned on to heat all the equipment to be repaired. It can be understood that the power supply of the maintenance area 9 is selected according to the specific power supply conditions of the area. If photovoltaic power supply is convenient, the second heating blower can be powered by photovoltaic power, or by wind power, or by the grid. The power supply form can be diversified to obtain the most economical power supply method.

[0021] In this embodiment, a vehicle-mounted constant temperature solution is provided. In another embodiment, the radiator of the transport vehicle can be modified, and an air duct can be set on the radiator. A common blower is used to connect the network pipe, and then connected to the cabinet. The heat generated by the vehicle itself during operation is directly used for heating and constant temperature. This solution is more suitable for non-extreme climate areas, and the specific transport constant temperature and antifreeze solution is selected according to actual usage needs.

[0022] To be more specific, a one-way sealing plate is provided inside the air inlet 11, and a one-way sealing plate is provided outside the air outlet 12. During the transportation or storage of the energy storage equipment, such as in a normal temperature area, no heating is provided, and the one-way sealing plates of the air inlet and the air outlet are not opened. When entering a low-temperature cold area and turning on the heating blower, the one-way sealing plates at both locations will automatically open under the action of pressure, thereby achieving air circulation and improving heating efficiency.

[0023] To be more specific, the outer layers of the first bellows 4 and the second bellows 6 are provided with a thermal insulation cotton layer 7. The thermal insulation cotton layer provided on the outer layer of the bellows can effectively insulate the bellows, especially in the maintenance area where centralized heating is provided. Since the pipelines are long, the bellows need to be insulated to ensure the heating effect.

[0024] To be more specific, the second corrugated pipe 6 includes a long air duct and several bent short pipes connected thereto. There is a short pipe on the long air duct connected to the second heating blower 2, and the bent short pipe matches the air inlet 11. In this embodiment, the maintenance area has fixed maintenance stations for energy storage equipment. The long air duct is the main air duct, and the bent short pipes are branch pipes. All energy storage equipment are connected to the long air duct for heating, thereby realizing centralized heating.

[0025] To be more specific, the transport vehicle 5 is also provided with a diesel generator 8, which is electrically connected to the first heating blower 2. In this embodiment, a vehicle-mounted power supply method is illustrated, that is, the first heating blower is powered by a diesel generator. The diesel generator is a detachable structure. When the energy storage equipment is installed, if there is no temporary power supply at the site, the diesel generator can continue to be used to power the blower.

[0026] After adopting the above technical solution, the beneficial effects of the utility model are as follows: it effectively solves the problem of batteries and low-temperature-sensitive equipment in the energy storage system being frozen during the transportation of energy storage equipment in a low-temperature environment; it solves the problem of batteries and low-temperature-sensitive equipment in the energy storage system being frozen when the energy storage equipment is temporarily parked in a low-temperature environment during construction and installation; it solves the problem of batteries and low-temperature-sensitive equipment in the energy storage system being frozen when the energy storage equipment is in a low-temperature environment during shutdown for inspection or maintenance.

[0027] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
