As shown in FIG. 1, in order to achieve the above object, the present invention provides a battery isolation device 1. The device mainly comprises a box body 11, a falling sand mechanism 12 and a battery roller table 13. A leakage plate 111 having a plurality of sand leakage holes 1111 is disposed in the casing 11, and the leakage plate 111 divides the casing 11 into a first cavity and a second cavity. The first cavity is mainly used for storing the isolation sand 3, for example, the top of the first cavity is provided with a sand loading port 113, and the sand filling port 113 can be equipped with a corresponding sanding cover 114, and the isolation sand 3 to be used can pass The sanding port 113 is placed in the first cavity.

The battery roller table 13 is disposed within the second cavity, and the battery roller 13 extends from the battery inlet 112 to the opposite side of the second cavity. The battery roller 13 mainly includes a roller ramp 131 and a plurality of sets of unpowered rollers 132 disposed on the roller ramp 131. The unpowered roller 132 is mainly used to reduce the power battery 4 under the influence of its own gravity on the roller ramp. The friction during sliding on 131. In this way, the power battery 4 entering the second cavity can be automatically moved to the target position along the set of unpowered rollers 132 under the action of its own gravity. Preferably, the sand leakage plate 111 may be provided with a plurality of corresponding slopes around the sand leakage holes 1111 on the side where the first cavity is formed (for example, an annular slope which is gradually increased in thickness from the leakage hole 1111 to the outer edge), thereby The sand leakage hole 1111 and the annular slope surface form a funnel shape, which facilitates gathering the isolation sand 3 to the nearest sand leakage hole 1111, and speeds up the flow speed of the isolation sand 3. Of course, those skilled in the art can conceive that the sand leakage plate 111 can also be provided with no inclined surface, and can be arranged in other structural forms capable of accelerating the accumulation and flow of the isolation sand 3.

According to the orientation shown in FIG. 1, the sand leakage plate 111 disposed in a substantially horizontal direction partitions the casing 11 into a first cavity located above the leakage board 111 and a second cavity located below the leakage board 111, and the leakage board A plurality of sand leakage holes 1111 are disposed on the 111, and a plurality of corresponding slopes are disposed around the plurality of sand leakage holes 1111. The isolation chamber 3 is stored in the first cavity, and the top surface of the first cavity is provided with a sand loading port 113 and a corresponding sanding cover 114. The battery inlet 132 is opened on the right side of the second cavity, and the battery roller 13 disposed in the second cavity extends from the battery inlet 112 to the left side of the second cavity. There are several groups on the roller ramp 131 of the battery roller table 13 The power roller 132 is unmanned, and the roller ramp 131 of the battery roller 13 is disposed toward the left side surface of the second cavity.

As shown in FIGS. 2 and 3, the falling mechanism 12 mainly includes a partition 121, a first rope structure 123, and a guide wheel 124. The bottom of the partition plate 121 is provided with a plurality of pulleys 125. The partition plate 121 is disposed on a side of the second cavity near the sand leakage plate 111, and the guide wheel 124 is relatively fixed to the casing 11. A plurality of pulleys 125 are disposed on a side of the partition plate 121 away from the sand leakage plate 111, and a plurality of partition holes 122 corresponding to the sand leakage holes 1111 are defined in the partition plate 121. A first slide 115 that is matched with the plurality of pulleys 125 is also disposed in the second chamber, and the partition 121 can be moved by sliding on the first slide 115 by the plurality of pulleys 125. The first end of the first rope structure 123 is connected to the side of the second cavity away from the sand leakage plate 111, and the second end of the first rope structure 123 is connected to the partition 121 by bypassing the guide wheel 124. In the process of moving the power battery 4 to the target position, the first rope structure 123 is pushed by the power battery 4, and the first rope structure 123 pulls the partition plate 121 to slide on the first slide 115 relative to the sand leakage plate 111, so that A plurality of sand leakage holes 1111 are at least partially aligned with the corresponding plurality of baffle holes 122, and the aligned passages allow the isolation sand 3 to flow from the first cavity into the second cavity and bury the power battery 4 at the target location. Preferably, the first rope structure 123 may be a steel cord. Of course, the specific form and material of the first rope structure 123 are not fixed, and those skilled in the art can flexibly adjust according to the specific application environment, as long as the first rope structure 123 adopting the form and material can be pushed and pulled by the power battery 4. The partition 121 moves.

Of course, it will be understood by those skilled in the art that the first cavity and the second cavity may also be relatively independent box structures, such as a first case and a second case. In this case, the sand leakage plate 111 corresponds to the bottom of the first case. The top of the box of the second box is a coverless structure, and the first slide 115 can be fixed to the top of the box of the second box by welding, screwing or the like.

It should be noted that the above-mentioned target position may be a position where the power battery 4 can be arranged when at least partially aligning the plurality of sand holes 1111 with the plurality of the partition holes 122. Specifically, the position may be when the hole axes of the plurality of sand leakage holes 1111 are in a state of being collinear with the hole axes of the corresponding plurality of the plate holes 122 (ie, the sand leakage holes 1111 and the partition holes 122 are completely aligned or The projection of one of the holes is included in the projection of the other hole), the position at which the power battery 4 is stopped after pushing the first rope structure 123. This position allows the isolation sand 3 to quickly flow into the second chamber and bury the power battery 4. Of course, the position may also be a position when the plurality of sand leakage holes 1111 and the corresponding plurality of the partition holes 122 are partially aligned, and the power battery 4 pushes the first knot. The position stopped after the structure 123. This position allows the isolation sand 3 to flow into the second cavity faster and bury the power battery 4.

According to the orientation shown in FIG. 3, the partition plate 121 of the falling sand mechanism 12 is disposed below the sand leakage plate 111 in a substantially horizontal direction, and a plurality of pulleys 125 are disposed at the bottom of the partition plate 121, and the partition plate 121 is provided with a plurality of leaks. A plurality of baffle holes 122 corresponding to the sand holes 1111. The first slide 115 is disposed below the partition 121 in a substantially horizontal direction, and the guide wheel 124 is disposed on the left side of the partition 121. The left end of the first rope structure 123 is fixedly connected to the bottom surface of the second cavity in a substantially vertical direction. The right end of the first rope structure 123 is wound around the guide wheel 124 and is fixedly connected to the left end of the partition 121 in a substantially horizontal direction.

As shown in FIG. 3 and FIG. 4 , the battery isolation device 1 further includes a sand blocking door 14 . The casing 11 is further provided with a second sliding passage 116 corresponding to the sand blocking door 14 , and the sand blocking door 14 can slide along the second sliding passage 116 . The way to close the battery inlet 112. Referring to FIG. 4, the falling mechanism 12 further includes a second tether structure 126 and a latch 127. The first end of the second rope structure 126 is connected to the partition 121, and the second end of the second rope structure 126 is connected to the first end of the plug 127. In addition, the housing 11 is further provided with a pin sleeve 117 corresponding to the latch 127. The second end of the latch 127 can fix the sand blocking door 14 by passing through the pin sleeve 117. And during the process of the power battery 4 reaching the target position, the second rope structure 126 can pull the latch 127 away from the pin sleeve 117, thereby enabling the sand blocking door 14 to slide along the second slide 116, and the battery inlet 112 is closed by the sliding.

It can be seen that the length of the pin 127 is much larger than the length of the pin sleeve 117 so that in the assembled state, the first end of the pin 127 can be located within the pin sleeve 117, and the second end of the pin 127 can extend the pin sleeve 117 and the extended portion can be sufficient to support the sand blocking door 14 to maintain its current position.

In the orientation shown in FIG. 4, the second slide 116 is disposed in a substantially vertical direction outside the casing 11 corresponding to the right side surface of the first cavity, and the sand blocking door 14 can be substantially vertical on the second slide 116. Slide in the direction. The left end of the second rope structure 126 is fixedly coupled to the right end of the partition 121 in a substantially horizontal direction, and the right end of the second rope structure 126 is fixedly coupled to the left end of the latch 127 in a substantially horizontal direction. The pin sleeve 117 is disposed on the right side surface of the first cavity in a substantially horizontal direction, and the right end of the pin 127 can fix the sand blocking door 14 by passing through the pin sleeve 117, that is, the bottom of the sand blocking door 14 can be extended by the pin 127 Partially lifted up.

As described above, when the battery isolating device 1 is in the non-use state, the plurality of sand leakage holes 1111 and the corresponding bulkhead holes 122 are in a state of being "staggered" from each other, and this "staggered" state can be made in the first cavity. The isolation sand 3 cannot flow into the second cavity. When the battery is separated When the device 1 enters the use state, the power battery 4 in an abnormal state can be moved by the battery inlet 112 to the target position along the roller ramp surface 131 of the inclined battery roller 13 under its own gravity, and moved in the power battery 4 In the process of reaching the target position, the first rope structure 123 is pushed to generate a thrust after contacting the first rope structure 123, and the thrust causes the first rope structure 123 to pull the partition 121 to move relative to the sand leakage plate 111, so that a plurality of leaks The sand hole 1111 is at least partially aligned with the plurality of baffle holes 122 to form a passage, thereby causing the isolation sand 3 to flow into the second cavity and bury the power battery 4 at the target position. While the first rope structure 123 pulls the partition 121 to move, the partition 121 can pull the second rope structure 126, and the second rope structure 126 pulls the bolt 127 away from the sleeve 117, so that the sand blocking door 14 is along the second sliding path. 116 slides and closes the battery inlet 112, and the isolation of the power battery 4 is completed. It can be seen that by the cooperation between the self-gravity of the power battery 4, the inclined battery roller table 13, the first rope structure 123, the sand leakage plate 111 and the partition plate 121, the entire power battery 4 can be automatically completed without manual intervention. Isolation process. Therefore, the operating efficiency of the device is significantly improved. Moreover, since it is not necessary for the worker to approach the power battery 4 (such as overheating) in an abnormal state, the safety of the device in completing the isolation of the power battery 4 is greatly improved. Further, the falling sand mechanism 12 can be reused due to its simple structure, reliable operation, and operation.

In addition, in order to facilitate further processing of the isolated power battery 4, in a possible embodiment, a plurality of auxiliary wheels 15 may also be installed at the bottom of the casing 11 to improve the usability of the isolation device. Further, referring to FIG. 1, in order to prevent the power battery 4 from colliding with the inner wall of the second casing 11 due to excessive inertia, a buffer may be provided on the inner wall of the left side of the second cavity corresponding to the moving direction of the power battery 4. Layer 16 (such as a rubber layer) to further increase the safety of the battery isolation device 1. In a preferred embodiment, the position of the left side of the power battery 4 in the second cavity when it abuts against the buffer layer 16 can be defined as the aforementioned target position.

As shown in FIG. 5, the present invention also provides a charging and discharging station 2 having the above-described battery isolating device 1, which mainly includes a power changing robot (not shown) and a battery conveying device 22. Wherein, the battery outlet 23 may be disposed at a corresponding position, and the installation position of the battery outlet 23 should correspond to the installation position of the battery inlet 112 of the battery isolation device 1, that is, the power battery 4 from the battery outlet 23 can smoothly pass the battery. The inlet 112 enters the first cavity. For example, in the case where the battery isolating device 1 is placed next to the battery outlet 23 of the charging station 2, the power battery 4 can pass through the battery outlet 23 directly into the second cavity of the battery isolating device 1 through the battery inlet 112. The battery delivery device 22 mainly includes a carrying platform 221 and a driving mechanism (not shown), and the carrying platform 221 is mainly used for carrying the bearing The power battery 4 in an abnormal state, and the power-changing robot can move the power battery 4 to the carrier platform 221. The drive mechanism is primarily used to transport the power battery 4 carrying the platform 221 to a position that enables it to enter the second cavity. For example, the drive mechanism may include a plurality of sets of power rollers 222 disposed on the carrier platform 221, ie, the power roller 222 is configured with a corresponding power unit (such as a motor). In this way, under the driving of the motor, the power battery 4 on the carrying platform 221 can be moved from the battery outlet 23 to the battery inlet 112 of the battery isolating device 1.

According to the orientation shown in Fig. 5, a battery delivery device 22 is provided in the charging and discharging station 2, for example, the battery delivery device 22 is disposed at the bottom of the energy storage unit 21 for storing and charging the depleted battery. A plurality of sets of power rolls 222 are disposed on the carrying platform 221 of the conveyor, and the height of the carrying platform 221 is matched to the battery inlet 112. Correspondingly, the battery outlet 23 is disposed on the housing/wall of the energy storage unit 21 located on the left side of the battery delivery device 22, and the battery outlet 23 is positioned and shaped and disposed on the right side of the second cavity of the battery isolation device 1. The battery inlet 112 corresponds so that after the drive mechanism moves the power battery 4 out of the battery outlet 23, it can just dock to the battery inlet 112 and enter the second cavity through the battery inlet 112.

Further, in order to ensure safe operation of the charging and discharging station 2, a one-way door 24 may be provided at the battery outlet 23, and the one-way door 24 only allows the power battery 4 to move from the battery outlet 23 to the battery inlet 112. In this way, after the power battery 4 moves out of the battery outlet 23, the one-way door 24 is closed, and the charging and replacing station 2 is separated from the external environment to ensure the safe operation of the charging and replacing station 2.

With further reference to FIG. 5, preferably, at the bottom of the casing 11 of the battery isolating device 1, an auxiliary wheel 15 is provided, the arrangement of the auxiliary wheel 15 can increase the mobility of the battery isolating device 1, thereby facilitating the being The isolated power battery 4 is further processed. Of course, those skilled in the art may think that the bottom of the casing 11 of the battery isolation device 1 may not be provided with the auxiliary wheel 15, but the battery isolation device 1 may be directly disposed at a fixed position in the charging and replacing station 2 (refer to FIG. 6). ).

The charging and replacing station 2 having the battery isolating device 1 can move the power battery 4 in an abnormal state to the battery isolating device 1 through the power changing robot and the battery conveying device 22, and use the battery isolating device 1 to discharge the power battery 4 in an abnormal state. isolation. That is to say, in the isolation process of the power battery 4, the movement of the power battery 4 can be realized without introducing an external device, that is, the operation can be completed only by replacing the power-changing robot in the power station 2, and the isolation step is simple. Further, since the process of isolating the power battery 4 by the battery isolating device 1 does not require a staff-assisted operation, that is, the battery isolation device 1 can be realized only by the action of its own gravity. The second cavity is buried and isolated within the second cavity. Therefore, not only the operation efficiency of the isolation process is improved, but also the safety of the isolation operation is greatly improved since the worker is not required to approach the power battery 4 in an abnormal state.

As shown in FIG. 7, the present invention also provides a battery isolation method, which is mainly used for isolating the power battery 4 in an abnormal state in a buried manner. For example, the battery isolation device 1 is applied to the charging and replacing station 2, and the method mainly includes the following steps:

S100. The power changing robot moves the power battery 4 in an abnormal state to the carrying platform 221 of the battery conveying device 22.

S200, the battery transport device 22 moves the power battery 4 to the battery inlet 112, and after the power battery 4 moves out of the battery outlet 23, the one-way door 24 closes the battery outlet 23.

The battery delivery device 22 can transport the power battery 4 from the battery outlet 23 to the battery inlet 112 of the battery isolation device 1 through the power-changing robot, thereby causing the battery isolation device 1 to isolate the power battery 4. It can be seen that the power battery 4 is replaced by the power-changing robot instead of the external device, and the worker does not need to approach the power battery 4 during the entire isolation process, thereby greatly improving the safety of the isolation operation. In addition, the setting of the one-way door 24 can separate the charging and replacing station 2 from the external environment after the power battery 4 moves out of the battery outlet 23, further ensuring the operational safety of the charging and replacing station 2.

In addition, the implementation process of the battery isolation method mainly includes: the power-changing robot moves the power battery 4 to the battery delivery device 22; the battery delivery device 22 moves the power battery 4 to the battery inlet 112; the power battery 4 reaches the second under the action of its own gravity The target position of the cavity; and during the process in which the power battery 4 reaches the target position, the isolation sand 3 flows from the first cavity into the second cavity until the power battery 4 is buried. It can be seen that in the complete process of isolating the power battery 4, the power battery 4 is moved to the battery isolation device 1 by the cooperation of the power-changing robot and the battery delivery device 22, which saves cost since no external device needs to be introduced. The safety of the isolation work is greatly improved because no manual operation is required.
