DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0046] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.

[0047] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 5 As shown, a container yard energy storage integrated station is provided, which mainly includes: a yard body 1, a plurality of lifting equipment 2 and a power grid system. A placement platform 101 away from the ground is arranged inside the yard body 1, and the placement platform 101 is suitable for stacking containers 4. Multiple lifting equipment 2 are arranged at intervals on the top of the yard body 1. Each lifting equipment 2 is provided with a generator-electric integrated machine 3. The power grid system is electrically connected to the generator-electric integrated machine 3. The container yard energy storage integrated station has an energy storage state and a power generation state. In the energy storage state, the power grid system drives the lifting equipment 2 through the generator-electric integrated machine 3 to drive the container 4 to be stacked on the placement platform 101. In the power generation state, the container 4 falls by its own weight and drives the generator-electric integrated machine 3 to generate electricity and transmit it to the power grid system.

[0048] In one embodiment, the container yard energy storage integrated station of the utility model embodiment can store energy and generate electricity according to the needs of the power grid system. In the energy storage state, multiple lifting equipment 2 are used to consume electrical energy and store the container 4 on the placement platform 101, which is stored in the form of potential energy. In the power generation state, the potential energy of the container 4 is used to drive the power generation electric integrated machine 3 to generate electricity, thereby reducing energy consumption and use costs. In addition, the integrated setting of the yard and the energy storage power station can save the overall occupied area of ​​the yard and the energy storage power station, improve land utilization, and further reduce use costs.

[0049] Specifically, since the placement platform 101 is far from the ground, the container 4 has a certain potential energy on the placement platform 101. In the energy storage state, the lifting device 2 consumes electric energy to lift the container 4 from the lower ground or truck to the higher placement platform 101. In the power generation state, the lifting device 2 supports the container 4, and the container 4 falls from the higher placement platform 101 to the lower ground or truck by its own weight.

[0050] In one embodiment, Figure 1 As shown, the placement platform 101 includes an energy storage area 1011 and an energy release area 1012, wherein the energy storage area 1011 is arranged above the energy release area 1012, and the container 4 has a certain potential energy on the energy storage area. In the energy storage state, the lifting equipment 2 consumes electric energy to lift the container 4 from the lower energy release area 1012 to the higher energy storage area 1011. In the power generation state, the lifting equipment 2 supports the container 4, and the container 4 falls from the higher energy storage area 1011 to the lower energy release area 1012 by its own weight.

[0051] It should be noted that the embodiment of the utility model does not limit the lifting device 2, as long as the lifting device 2 can lift or lower the container 4.

[0052] In one embodiment, Figure 4 and Figure 5 As shown, each lifting device 2 mainly includes: a sling 201, a driving member 202 and a flexible rope 204. The sling 201 is suitable for connecting to a container 4. The driving member 202 is arranged on the lifting device 2 and is electrically connected to the generator and motor integrated machine 3 through a transmission assembly 203. The flexible rope 204 connects the sling 201 and the driving member 202 respectively. The driving member 202 can be a drum, a winch, etc.

[0053] In the embodiment of the utility model, in the energy storage state, the driving member 202 rotates, and the driving member 202 transmits the motion to the sling 201 through the flexible rope 204. The sling 201 drives the container 4 to rise to the corresponding placement platform 101, and converts the excess electric energy into the potential energy of the container 4. In the power generation state, the container 4 falls by its own weight and drives the driving member 202 to rotate in the opposite direction through the flexible rope 204. The driving member 202 drives the generator and electric integrated machine 3 to generate electricity, converting the potential energy of the container 4 into electric energy and transmitting it to the power grid system, making up for the shortage of electric energy and improving the utilization rate of energy.

[0054] Specifically, twist locks are respectively provided at the four corners of the spreader 201. When the four corners of the spreader 201 are aligned with the four corners of the container 4, the spreader 201 and the container 4 are fixed by the twist locks.

[0055] In one embodiment, the transmission assembly 203 includes a reduction box, the input end of which is connected to the generator-motor integrated machine 3 through a coupling, and the output end of which is connected to the driving member 202 through another coupling. The speed of the generator-motor integrated machine 3 can be reduced by the reduction box, which facilitates the start of the spreader 201 to move the container 4 and facilitates use.

[0056] In one embodiment, Figure 4 As shown, each lifting device 2 further includes: a cantilever 205, a first moving mechanism 206 and a second moving mechanism 207. The cantilever 205 is arranged at the top of the yard body 1. A pair of first moving mechanisms 206 are arranged, respectively located at the two ends of the cantilever 205, and are used to drive the cantilever 205 to move along a length direction perpendicular to the cantilever 205. The direction here is the horizontal direction. The length direction of the cantilever 205 is as shown in FIG. Figure 4 As shown by arrow A in FIG. The second moving mechanism 207 is disposed on the cantilever 205 , and the hanger 201 is disposed on the second moving mechanism 207 . The second moving mechanism 207 can drive the hanger 201 to move along the length direction of the cantilever 205 .

[0057] The embodiment of the utility model can drive the cantilever 205 of the lifting device 2 and the second moving mechanism 207 to move in a length direction perpendicular to the cantilever 205 through the first moving mechanism 206, so as to adjust the position of the lifting device 2 relative to the container 4 in the length direction perpendicular to the cantilever 205. The second moving mechanism 207 can drive the sling 201 to move in the length direction of the cantilever 205, so as to adjust the relative position of the sling 201 and the cantilever 205 in the length direction of the cantilever 205.

[0058] It should be noted that the first moving mechanism 206 and the second moving mechanism 207 can both adopt any existing structure as needed, such as a self-moving device.

[0059] In one embodiment, a plurality of first rails 102 are provided on the top of the yard body 1 along a length direction perpendicular to the cantilever 205, and each first moving mechanism 206 is correspondingly provided on one first rail 102 and can slide along the first rail 102. The first moving mechanism 206 can move along a length direction perpendicular to the cantilever 205 through the first rail 102, so as to drive the cantilever 205 of the lifting device 2 and the second moving mechanism 207 to move along a length direction perpendicular to the cantilever 205.

[0060] In one embodiment, the cantilever 205 is provided with a second track along its length direction, and the second moving mechanism 207 is provided on the second track and can slide along the second track. The second moving mechanism 207 can move along the length direction of the cantilever 205 through the second track, so as to drive the sling 201 to move along the length direction of the cantilever 205.

[0061] In one embodiment, the flexible cable 204 is a steel wire rope, which has a simple structure and low use cost.

[0062] In one embodiment, Figure 2 As shown, the placement platform 101 is provided with a plurality of placement racks 1013 arranged in a row, and a corresponding lifting device 2 is provided at the upper end of each placement rack 1013. Each lifting device 2 can store and retrieve containers 4 on a placement rack 1013 individually, which can improve the working efficiency of the container yard energy storage integrated station.

[0063] In order to realize the basic functions of the container yard energy storage integrated station, the container yard energy storage integrated station in this embodiment may also include other necessary modules or components, such as control systems, wires, etc. It should be noted that the other necessary modules or components included in the container yard energy storage integrated station can be selected from any suitable existing structures. In order to clearly and briefly explain the technical solution provided by this embodiment, the above-mentioned parts will not be repeated here, and the drawings in the specification have also been simplified accordingly. However, it should be understood that the scope of the utility model is not limited by this.

[0064] According to an embodiment of the utility model, on the other hand, a container yard energy storage system is also provided, including: a new energy power station and a container yard energy storage integrated station, and the power grid system is electrically connected to the new energy power station. The new energy power station is used to supply power to the terminal, such as a photovoltaic power station using solar power generation, a wind power station using wind power generation, etc.

[0065] Because the container yard energy storage system includes a container yard energy storage integrated station, it has the same effect as the container yard energy storage integrated station, that is, in the energy storage state, multiple lifting equipment 2 are used to consume electrical energy and the container 4 is stored on the placement platform 101, which is stored in the form of potential energy. In the power generation state, the potential energy of the container 4 is used to drive the power generation electric integrated machine 3 to generate electricity, thereby reducing energy consumption and use costs. In addition, the integrated setting of the yard and the energy storage power station can save the overall occupied area of ​​the yard and the energy storage power station, improve land utilization, and further reduce the use cost.

[0066] It should be noted that the new energy power station must first meet the operational energy consumption of the terminal. Since the power source of the new energy power station is unstable, its power generation is also unstable. In some periods, there is a surplus of electricity, that is, the power generation exceeds the power consumption of the terminal. In some periods, there is a deficit of electricity, that is, the power generation cannot meet the power consumption of the terminal.

[0067] In one embodiment, the integrated container yard energy storage station enters the energy storage state in response to a surplus of electricity generated by the renewable energy power generation station. The integrated container yard energy storage station enters the power generation state in response to a deficit of electricity generated by the renewable energy power generation station.

[0068] The embodiment of the utility model can store energy or generate electricity according to the actual power generation state of the new energy power station. When the power of the new energy power station is in surplus, that is, after meeting the operating energy consumption of the terminal, the excess power is supplied to the container yard energy storage integrated station, and the container yard energy storage integrated station enters the energy storage state, using multiple lifting equipment 2 to consume excess power and lift the container 4 from the lower energy release area 1012 to the higher energy storage area 1011, and store the surplus power in the form of potential energy. When the power of the new energy power station is in deficit and cannot meet the operating energy consumption of the terminal, the container yard energy storage integrated station enters the power generation state, and the container 4 falls from the higher energy storage area 1011 to the lower energy release area 1012 by its own weight, and drives the generator electric integrated machine 3 to generate electricity to meet the operating energy consumption of the terminal. That is, the container yard energy storage integrated station is used for peak shaving and valley filling of the new energy power station, which can improve the use stability of the new energy power station.
