Description

Technical Field

[0001] The present invention relates to the technical field of power exchange facilities, and in particular to a water-cooled fire-fighting power exchange station. Background Art

[0002] As global attention to environmental protection continues to rise, energy transformation in the transportation sector has become an inevitable trend. With its significant advantages of low emissions and low pollution, electric vehicles are gradually replacing fuel vehicles and becoming a new direction for the development of the industry. Among them, heavy-duty trucks, as the main model for road freight, consume a lot of fuel, and their exhaust emissions contain a large amount of pollutants such as nitrogen oxides and particulate matter, causing serious pollution to the environment. Therefore, the development of electric heavy-duty trucks has become a key measure to alleviate environmental pollution problems and promote the green transformation of the transportation industry.

[0003] The construction of battery swap stations for electric heavy trucks is crucial to improving the efficiency of heavy truck use and accelerating the popularization of electric heavy trucks. Compared with traditional charging technology, battery swap technology can replace fully charged batteries for vehicles in a short period of time, greatly saving the time waiting for charging and effectively improving the operating efficiency of electric heavy trucks. However, due to the long mileage and heavy load of electric heavy trucks, the demand for battery power is extremely large. This results in a high power load during battery charging in the battery swap station, accompanied by a large amount of heat dissipation.

[0004] At present, battery swap stations generally adopt the mode of charging in the station, that is, the replaced empty batteries are charged centrally. However, the fire protection measures of existing battery swap stations are still imperfect, and it is difficult to deal with the fire risks that may occur during the battery charging process. During the charging process, lithium batteries are very likely to cause fires due to thermal runaway, overcharging, short circuits and other reasons. Once a fire occurs, the fire spreads rapidly and is accompanied by a large amount of toxic and harmful gases. Due to the slow response speed of the existing fire protection system and limited fire extinguishing means, when the battery catches fire, the staff often do not have time to take effective measures to extinguish the fire, resulting in major property losses and even casualties.

[0005] In addition, as the scale of battery swap stations continues to expand, the number of battery storage and charging equipment continues to increase, and the risk of fire is further increased. If the fire cannot be controlled in a timely and effective manner, it will not only cause devastating damage to the battery swap station itself, but may also affect surrounding buildings and facilities, causing more serious safety accidents. Therefore, the development of a complete battery swap station fire protection system is an inevitable trend in the development of battery swap stations. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Example

[0022] See also Figure 1 As shown, this embodiment provides a water-cooled fire-fighting battery swap station, which includes: a charging and discharging mechanism 100, the charging and discharging mechanism 100 includes a container 110 and a plurality of charging piles 120, the container 110 is connected to a plurality of temperature and smoke sensors 113, and the container 110 is provided with a plurality of battery bottom brackets 114 for carrying batteries, and the plurality of battery bottom brackets 114 are respectively connected to the plurality of charging piles 120; a cooling mechanism 300, the cooling mechanism 300 is arranged on one side of the container 110, and includes a water cooling box 310 and a lifting and lowering load box 311. The tray 320 contains coolant inside the water cooling box 310, and the lifting tray 320 is lifted and lowered along the height of the water cooling box 310. The thermal runaway battery is arranged in the lifting tray 320 to be immersed in the coolant along with the lifting tray 320; the battery moving mechanism 200 includes at least a moving hanger 220, and the moving hanger 220 is connected to the top of the container 110 and can be moved horizontally and / or vertically to move the thermal runaway battery from the container 110 to the water cooling box 310.

[0023] The water-cooled fire-fighting battery swap station described in the present invention charges and discharges the battery through the charging and discharging mechanism 100. If thermal runaway of the battery occurs during this process, the internal environment of the container 110 can be monitored in real time through the temperature and smoke sensor 113, and then the overheated battery is moved to the cooling mechanism 300 through the battery moving mechanism 200, thereby protecting other batteries and improving the safety performance of the battery swap station. Compared with conventional battery swap stations, this application not only has sensitive detection and accurate positioning, but also has a fast response speed, and can eliminate safety hazards before large-scale overheating occurs. Therefore, it has the advantages of strong controllability, flexible use, high safety and high automation, and provides new ideas for the layout design of battery swap stations.

[0024] It should be noted that, for ease of description, in this embodiment, the length direction of the container 110 is defined as the first direction X, the width direction of the container 110 is defined as the second direction Y, and the height direction of the container 110 is defined as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other in pairs, and the first direction X and the second direction Y are located in the same plane.

[0025] See also Figure 2 and Figure 3 As shown, in this embodiment, the container 110 is used to provide an installation and connection platform for its internal structure and the battery moving mechanism 200, and on the other hand, it is used to provide a reference point for the layout position of the cooling mechanism 300 and the parking position of the heavy truck 600 to be replaced. A plurality of battery bases 114 are arranged at intervals inside it to charge / discharge multiple batteries at the same time. Furthermore, the plurality of battery bases 114 in this embodiment are respectively connected to at least one charging pile 120, and the charging pile 120 is additionally provided with a temperature detection structure inside, thereby acting synchronously with the temperature and smoke sensor 113 to achieve a dual protection effect against battery overheating.

[0026] Furthermore, the container 110 in this embodiment includes a box body 111 and a top cover 112, wherein the top cover 112 is detachably connected to the top of the box body 111, a plurality of temperature and smoke sensors 113 are evenly arranged on the top cover 112, and a plurality of battery bases 114 are evenly spaced and arranged on the bottom surface of the box body 111. Furthermore, the plurality of temperature and smoke sensors 113 in this embodiment are spaced along the first direction X, and the spacing distance between two adjacent temperature and smoke sensors 113 is not greater than the width of one temperature and smoke sensor 113, thereby achieving a comprehensive detection of the internal environment of the box body 111 in the first direction X. In different embodiments, the specific number and setting position of the temperature and smoke sensors 113 and the battery base 114 can be adaptively adjusted according to actual use requirements, and the present invention does not impose specific restrictions on this.

[0027] Specifically, see Figure 4 As shown, the box body 111 in this embodiment includes a frame 1111, a side baffle 1112 and a sliding door assembly 1113, wherein the side baffle 1112 is connected to two opposite sides of the frame 1111 in the second direction Y, the sliding door assembly 1113 is arranged on at least one side of the frame 1111 in the first direction X, and the cooling mechanism 300 is arranged corresponding to the sliding door assembly 1113. Among them, the frame 1111 plays the main supporting role of the box body 111, and the side baffle 1112 is symmetrically arranged on two opposite sides of the frame 1111 in the second direction Y, which is used to seal and isolate the internal environment of the box body 111, thereby reducing the impact range when thermal runaway occurs, and further improving the safety protection of personnel; in this embodiment, two sets of sliding door assemblies 1113 are symmetrically arranged on both sides of the frame 1111 in the first direction X, thereby respectively corresponding to taking and placing batteries from the heavy truck 600 to be replaced and facilitating the transfer of thermal runaway batteries to the interior of the cooling mechanism 300.

[0028] Specifically, in this embodiment, two sliding door assemblies 1113 are provided in the first direction X, and the two sliding door assemblies 1113 on the same side are arranged opposite to each other to work together to realize the opening and closing of the box body 111. The structure of any sliding door assembly 1113 is the same, and only one of them is used as an example for description: the sliding door assembly 1113 includes a door body 1115, a push driver 1116 and a guide rod 1117, the push driver 1116 is arranged on the frame 1111, one end of the guide rod 1117 is connected to the working end of the push driver 1116, and the other end is connected to the door body 1115 to drive the door body 1115 to move along the second direction Y. In this embodiment, the push driver 1116 is preferably a linear motor, and the frame 1111 corresponding to the door body 1115 is provided with a first horizontal guide rail 1114 extending along the second direction Y, so as to allow the door body 1115 to open and close. Based on this structural setting, when the heavy truck 600 to be replaced with batteries moves to the vicinity of the box 111, the sliding door assembly 1113 on one side opens to facilitate battery replacement in the vehicle; when thermal runaway occurs, the sliding door assembly 1113 near the cooling mechanism 300 opens to facilitate the battery moving mechanism 200 to transfer the runaway battery to the inside of the cooling mechanism 300.

[0029] Further, see Figure 5 and Figure 6As shown, the cooling mechanism 300 also includes a lifting drive mechanism 330, and the lifting drive mechanism 330 includes a gear 333, a rack 334, a lifting guide rail 335 and a counterweight 336. The gear 333 is arranged at the top corner of the water cooling box 310, and the rack 334 is meshed with the gear 333. One end of the gear 333 is connected to the lifting plate 320, and the other end is connected to the counterweight 336. The mass of the counterweight 336 is greater than the unloaded mass of the lifting plate 320. Based on this, when the lifting plate 320 carries a thermal runaway battery inside, it can be lowered into the coolant of the water cooling box 310 under the action of gravity. Specifically, the lifting drive mechanism 330 in this embodiment also includes a rotary driver 331 and a transmission shaft 332. The rotary driver 331 is arranged at the top of the water cooling box 310, and a clamping module is provided inside the rotary driver 331. The transmission shaft 332 is connected to the working end of the rotary driver 331 and is connected to the gear 333. Based on this, when the thermal runaway battery is placed unstably, the rotary driver 331 is in a locked state until the battery is stabilized in the lifting carrier 320 and then descends, thereby avoiding the risk of tilting and falling due to battery shaking during the descent process. At the same time, it can also ensure that the thermal runaway battery is stably immersed in the coolant. In this embodiment, the rotary driver 331 is preferably a rotary motor, and in different embodiments, it can also be configured as other structures with a rotary locking function, and the present invention does not make specific restrictions on this.

[0030] In this embodiment, in order to facilitate cooperation with the battery moving mechanism 200 , a first horizontal guide rail 1114 is provided on the top of the box body 111 in this embodiment. The first horizontal guide rail 1114 extends along the first direction X, and the battery moving mechanism 200 is slidably connected to the first horizontal guide rail 1114 .

[0031] Specifically, see Figure 7 As shown, the battery moving mechanism 200 further includes a moving frame 240, the moving frame 240 is slidably connected to the container 110 along the first direction X, a second horizontal guide rail 210 is provided thereon, the second horizontal guide rail 210 extends along the second direction Y, and the moving spreader 220 is slidably connected to the second horizontal guide rail 210. Based on this structural design, the moving spreader 220 in this embodiment can realize movement in the first direction X and / or the second direction Y in a horizontal plane.

[0032] In this embodiment, the water-cooled fire-fighting battery swap station further includes a central control mechanism 400, and the charging and discharging mechanism 100, the battery moving mechanism 200, and the cooling mechanism 300 are respectively connected to the central control mechanism 400. In the actual operation process, the operator can control the above structures in real time through the central control mechanism 400, thereby improving the flexibility of the use of the device, and can also preset parameters through the central control mechanism 400, thereby improving the automation of the device.

[0033] In addition, the water-cooled fire-fighting battery swap station described in this embodiment also includes a monitoring room 500, which is arranged on one side of the container 110. The monitoring room 500 is arranged overhead, and an escalator 510 is connected to its bottom, and observation windows are provided on its side walls to facilitate monitoring and maintenance by operators.

[0034] In summary, the water-cooled fire-fighting battery swap station described in the present invention charges and discharges the battery through the charging and discharging mechanism 100. If thermal runaway of the battery occurs during this process, the internal environment of the container 110 can be monitored in real time through the temperature and smoke sensor 113, and then the overheated battery is moved to the cooling mechanism 300 through the battery moving mechanism 200, thereby protecting other batteries and improving the safety performance of the battery swap station. Compared with conventional battery swap stations, this application not only has sensitive detection and accurate positioning, but also has a fast response speed, and can eliminate safety hazards before large-scale overheating occurs. Therefore, it has the advantages of strong controllability, flexible use, high safety and high automation, and provides new ideas for the layout design of battery swap stations.

[0035] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
