Description

Technical Field

[0001] The present invention relates to the field of energy storage technology, and more specifically, to a self-unloading mobile energy storage cabin. Background Art

[0002] With the rapid development of social economy and the continuous improvement of infrastructure, the application demand of energy storage power stations is becoming more and more extensive. At present, energy storage power stations are mainly fixed power stations, which have disadvantages such as large size, heavy weight and immobility. Compared with fixed energy storage power stations, the invention of mobile energy storage power stations greatly meets the needs of different electricity usage scenarios, such as emergency response and disaster relief. Although ordinary emergency rescue vehicles can also achieve the above functions, the battery capacity they carry is limited and cannot meet the high-power and long-term power supply. Although the existing mobile energy storage power stations have achieved functions such as high-power power transfer to a certain extent, there are still some problems that need to be solved. For example, the existing mobile energy storage power stations require professional lifting equipment for auxiliary loading and unloading on the one hand, and it is difficult to overcome the placement problems caused by uneven roads on the other hand. Summary of the invention

[0003] In order to solve the application problems and transportation problems of loading and unloading and stable placement of mobile energy storage power stations, the present invention provides a self-unloading mobile energy storage cabin, which allows the energy storage cabin to lift itself and realize automatic loading and unloading of the mobile energy storage cabin without any lifting equipment.

[0004] In order to achieve these purposes and other advantages according to the present invention, a self-unloading mobile energy storage cabin is provided, comprising:

[0005] cabin body;

[0006] A levelness detection mechanism, which is arranged on the shelter body;

[0007] Four lifting mechanisms are respectively located at four right angles of the same rectangle and are respectively connected to the cabin body through driving mechanisms. The lifting ends of the lifting mechanisms are arranged downward and are vertically retracted. The driving mechanisms drive the corresponding lifting mechanisms to move inward to be stored on the side walls of the cabin body, or to move outward to be located outside the cabin body.

[0008] Furthermore, in the self-unloading mobile energy storage cabin, the levelness detection mechanism is a tilt sensor.

[0009] Furthermore, in the self-unloading mobile energy storage cabin, the lifting mechanism is a lifting cylinder.

[0010] Furthermore, in the self-unloading mobile energy storage cabin, the end of the lifting cylinder push rod is connected to a support leg, and the lower end of the support leg is provided with an in-position switch.

[0011] Furthermore, in the self-unloading mobile energy storage cabin, the driving mechanism includes:

[0012] Two supporting bases are arranged on the shelter body at an interval up and down;

[0013] Two mounting plates are arranged in parallel, one end of the two mounting plates is hinged to the two supporting bases respectively, and the other end of the two mounting plates is hinged to the lifting mechanism respectively;

[0014] The extension cylinder is arranged between the two mounting plates, one end of the extension cylinder is hinged to one of the support bases, and the other end of the extension cylinder is hinged to the mounting plate corresponding to the other support base.

[0015] Furthermore, in the self-unloading mobile energy storage cabin, the cylinder body of the extension cylinder is hinged to the support base located above, and the end of the push rod thereof is hinged to the mounting plate located below.

[0016] Furthermore, in the self-unloading mobile energy storage cabin, when the lifting mechanism is stored on the side wall of the cabin body, the two mounting plates are in a vertical state; when the lifting mechanism is located outside the cabin body, the two mounting plates are in a horizontal state.

[0017] The present invention also provides a self-unloading method of the self-unloading mobile energy storage cabin, comprising the following steps:

[0018] S1. After the mobile energy storage cabin is transported to the placement location by a transport vehicle, the driving mechanism drives the corresponding lifting mechanism to move outward to the outside of the transport vehicle;

[0019] S2, the lifting ends of the lifting mechanism move downward until they contact the ground;

[0020] S3, the level detection mechanism detects the level of the shelter body. If the shelter body is in a horizontal state, the lifting end of the lifting mechanism continues to extend to a predetermined height, and the transport vehicle drives away from under the shelter body;

[0021] S4, the lifting end of the lifting mechanism moves upward until the cabin body moves to a predetermined placement height, that is, the self-unloading of the mobile energy storage cabin is completed, and the driving mechanism drives the corresponding lifting mechanism to move inward to be stored on the side wall of the cabin body.

[0022] Furthermore, in the self-unloading method of the self-unloading mobile energy storage cabin, in S3, if the cabin body is in a tilted state, the lifting ends of the lifting mechanisms are controlled one by one to move downward until the cabin body is in a horizontal state.

[0023] Furthermore, in the self-unloading method of the self-unloading mobile energy storage cabin, when the lifting end of the lifting mechanism in S4 moves upward, the horizontality detection mechanism detects the horizontality of the cabin body. If the cabin body is in a horizontal state, the lifting end of the lifting mechanism continues to move upward until the cabin body moves to a predetermined placement height; if the cabin body is in an inclined state, the lifting mechanisms stop working, and the lifting ends of the lifting mechanisms are controlled one by one to move upward until the cabin body is in a horizontal state.

[0024] The beneficial effects of the present invention are:

[0025] In the self-unloading mobile energy storage cabin of the present invention, a four-link self-unloading lifting mechanism is arranged at the four corners of the cabin body, so that the cabin body can be loaded, unloaded and transported without the need for lifting equipment, thereby realizing the comprehensive application of reserve power in different scenarios. On the one hand, it solves the problem that the mobile energy storage cabin needs professional lifting equipment to assist in transportation, and on the other hand, it solves the problem that the mobile energy storage cabin can be lifted and placed horizontally on roads with different slopes, thereby effectively improving the environmental adaptability of the product.

[0034] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a self-unloading mobile energy storage cabin, comprising:

[0035] Shelter body 1; In this embodiment, the shelter body 1 can be an existing mobile energy storage shelter, such as Figure 1 As shown, the mobile energy storage cabin integrates modules such as the energy storage converter PCS module 11, the three-phase static transfer switch STS module 12, the grid cabinet module 13, the control cabinet 14, the fire cabinet 15 and the battery module 16. The mobile energy storage cabin connects the mobile energy storage cabin interface with the grid interface through the grid cabinet module, and other modules work at the same time to achieve effective storage of electricity.

[0036] A level detection mechanism, which is arranged on the shelter body 1, and the level detection mechanism is a tilt sensor;

[0037] Four lifting mechanisms 2 are respectively located at four right angles of the same rectangle and are respectively connected to the cabin body 1 through a driving mechanism 3. The lifting mechanism 2 is a lifting cylinder, and the end of the lifting cylinder push rod is connected to a leg 34, and the lower end of the leg 34 is provided with an in-position switch; the lifting end of the lifting mechanism 2 is arranged downward and vertically retracted, and the driving mechanism drives the corresponding lifting mechanism 2 to move inward to be stored on the side wall of the cabin body 1, or move outward to be located outside the cabin body 1.

[0038] In this embodiment, when the mobile energy storage cabin is used, Figure 3 As shown, the initial state is the folded state, and the lifting mechanism 2 is stored on the side wall of the cabin body 1. The mobile energy storage cabin that has been charged is transported to the designated place by a flatbed truck. The driver of the transport truck needs a suitable location to prepare to place the mobile energy storage cabin. If the inclination sensor prompts information such as excessive slope, the driver of the transport truck needs to find a suitable location again, otherwise, this place can be used as the location for placing the mobile energy storage cabin.

[0039] After the transport vehicle is parked, the transport vehicle driver holds the wireless display and control remote controller to operate. The wireless display and control remote controller is electrically connected to the four lifting mechanisms 2, the four driving mechanisms, the four in-position switches and the tilt sensor. First, the four driving mechanisms are controlled to work separately to drive the corresponding jacking cylinders to move outward to the outside of the shelter body 1. After the driving mechanisms stop working, the jacking cylinders are located outside the shelter body 1, and the push rods of the four jacking cylinders are located at the four right angles of the same rectangle, such as Figure 2 As shown, the energy storage cabin is in the unfolded state at this time. Then the lifting cylinder starts to work. When the legs 34 of the lifting cylinder touch the ground, the in-position switch contacts the ground and sends a signal to the wireless display and control remote controller, which controls the lifting cylinder to temporarily stop lifting. When the legs 34 of all the lifting cylinders touch the ground, the inclination sensor on the cabin body 1 measures the data and sends it to the wireless display and control remote controller, so that the push rod wireless display and control remote controller can determine whether the state of the cabin body 1 is horizontal at this time: if it is in a horizontal state, the four lifting cylinders continue to lift at the same time; otherwise, the lifting cylinder on which side the cabin body 1 tilts continues to lift, and so on, adjusting the extension of each lifting cylinder one by one to adjust the cabin body 1 to a horizontal state.

[0040] When the shelter body 1 is in a horizontal state, all the lifting cylinders continue to lift synchronously until the shelter body 1 reaches a predetermined height. If the shelter body 1 does not reach the predetermined height, the shelter body 1 continues to lift; if the shelter body 1 reaches the predetermined height at this time, the transport vehicle driver needs to re-operate the transport vehicle to drive the transport vehicle away from the bottom of the shelter body 1.

[0041] After the transport vehicle completely leaves the bottom of the shelter body 1, the transport vehicle driver continues to operate the wireless display and control remote control to control the mobile shelter body 1 to descend to a specified height or place it on the ground. When descending, the four lifting cylinders shrink at the same time. At this time, the data measured by the inclination sensor is used to determine whether the state of the shelter body 1 is horizontal. If it is horizontal, the four lifting cylinders continue to shrink at the same time. Otherwise, the lifting cylinder on the side where the shelter body 1 is higher continues to shrink, and so on. The extension of each lifting cylinder is adjusted one by one to adjust the shelter body 1 to a horizontal state.

[0042] When the shelter body 1 is in a horizontal state, all the lifting cylinders continue to shrink, and the leveling system determines whether the shelter body 1 has reached the predetermined height. If it has not reached the predetermined height, the shelter body 1 continues to shrink; if the shelter body 1 has reached the predetermined height at this time, the transportation and placement of the mobile shelter body 1 is completed. If the mobile shelter body 1 is to be placed on the ground, it is necessary to determine whether the bottom of the shelter body 1 is completely touching the ground. If it is not completely touching the ground, the lifting cylinders with a long extension distance continue to shrink, while the ones with a short extension distance will temporarily stop working until the bottom of the shelter body 1 is adjusted to be completely in contact with the ground. At this time, all the extension cylinders are retracted, and the transportation and placement of the mobile shelter body 1 is completed.

[0043] Preferably, as another embodiment of the present invention, the driving mechanism comprises:

[0044] Two supporting bases 31 are arranged on the shelter body 1 at an interval from top to bottom;

[0045] Two mounting plates 32 are arranged in parallel, one end of the two mounting plates 32 is hinged to the two supporting bases 31 respectively, and the other end thereof is hinged to the lifting mechanism 2 respectively;

[0046] The extension cylinder 33 is arranged between the two mounting plates 32. The cylinder body of the extension cylinder 33 is hinged to the supporting base 31 located above, and the end of the push rod thereof is hinged to the mounting plate 32 located below.

[0047] In this embodiment, the two support bases 31 are arranged at intervals up and down, and the connection line of the two support bases 31 is vertical. One end of the two mounting plates 32 is hinged to the two support bases 31, that is, the position of one end of the two mounting plates 32 is fixed, and the jacking cylinder is arranged vertically and is hinged to the other end of the two mounting plates 32, respectively. The axis of the jacking cylinder is parallel to the connection line of the two support bases 31, and the two mounting plates 32 are arranged in parallel. At this time, a parallelogram structure is formed, and the connection line of the two support bases 31 is fixed. At this time, the parallelogram structure can rotate around the two support bases 31. At this time, the extension cylinder 33 between the two mounting plates 32 can drive the parallelogram structure to rotate around the two support bases 31. When the parallelogram structure rotates to the specified position, the extension cylinder 33 is fixed, and then the jacking cylinder starts to move, which can lift the cabin body 1 off the ground or the flatbed truck, thereby forming a self-loading and unloading mechanism.

[0048] Preferably, as another embodiment of the present invention, when the lifting mechanism 2 is stored on the side wall of the cabin body 1, the two mounting plates 32 are both in a vertical state, and when the lifting mechanism 2 is located outside the cabin body 1, the two mounting plates 32 are both in a horizontal state.

[0049] like Figure 5 As shown, an embodiment of the present invention further provides a self-unloading method of the self-unloading mobile energy storage cabin, comprising the following steps:

[0050] S1, after the mobile energy storage cabin is transported to the placement position by a transport vehicle, the driving mechanism drives the corresponding lifting mechanism 2 to move outward to the outside of the transport vehicle;

[0051] S2, the lifting ends of the lifting mechanism 2 move downward until they touch the ground;

[0052] S3, the levelness detection mechanism detects the levelness of the shelter body 1:

[0053] If the shelter body 1 is in a horizontal state, after the lifting end of the lifting mechanism 2 continues to extend to a predetermined height, the transport vehicle drives away from under the shelter body 1;

[0054] If the shelter body 1 is in a tilted state, the lifting ends of the lifting mechanisms 2 are controlled to move downward one by one until the shelter body 1 is in a horizontal state;

[0055] S4, the lifting end of the lifting mechanism 2 moves upward until the cabin body 1 moves to a predetermined placement height, that is, the self-unloading of the mobile energy storage cabin is completed, and the driving mechanism drives the corresponding lifting mechanism 2 to move inward to be stored on the side wall of the cabin body 1;

[0056] When the lifting end of the lifting mechanism 2 moves upward, the level detection mechanism detects the level of the cabin body 1. If the cabin body 1 is in a horizontal state, the lifting end of the lifting mechanism 2 continues to move upward until the cabin body 1 moves to a predetermined placement height; if the cabin body 1 is in an inclined state, the lifting mechanisms 2 stop working, and the lifting ends of the lifting mechanisms 2 are controlled to move upward one by one until the cabin body 1 is in a horizontal state.

[0057] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
