Description

[Technical Field]

[0001] The present invention relates to the technical field of ground piles for container-type energy storage devices, and more particularly to a ground pile structure for fixing container-type energy storage devices. [Background technology]

[0002] A containerized energy storage system is a device for storing electrical energy, and is primarily composed of major components such as a battery pack, inverter, and control system. Its functions include storing electrical energy and releasing it when needed. Its main role is to balance power supply and demand, improve energy utilization efficiency, and realize peak shaving, valley filling, and emergency backup by storing excess electrical energy and releasing it during peak demand. It also supports important functions such as grid connection of renewable energy, and therefore, when used in conjunction with solar power generation equipment and wind power generation equipment, it ensures stable power generation using clean energy.

[0003] However, since solar power generation devices and wind power generation devices are often installed outdoors or in mountainous areas, containerized energy storage devices also need to be installed in these locations. Because the terrain in outdoors or mountainous areas is generally complex, after a ground pile structure is installed, the containerized energy storage device is fixed and connected to the ground pile structure, thereby ensuring the stability of the containerized energy storage device's position.

[0004] In conventional ground pile structures, anchor rods are usually used to fix the fixed frame to the ground. However, because conventional anchor rods are usually bare rods, the anchor rods are prone to tilting after being inserted into the ground, reducing the stability of the ground pile structure, which makes the containerized energy storage device prone to tilting, which has a serious impact on the safe operation of the containerized energy storage device.

[0005] In order to solve the above problems, there is a demand for a ground pile structure for fixing a container-type power storage device. Summary of the Invention [Problem to be solved by the invention]

[0006] The purpose of the present invention is to provide a ground pile structure for fixing a container-type energy storage device, thereby solving the problem described in the background art above that the conventional ground pile structure for a container-type energy storage device is prone to tilting after the anchor rods are inserted into the ground, causing the container-type energy storage device to tilt and affecting its safe operation. [Means for solving the problem]

[0007] To achieve the above object, the present invention provides the following technical solution: a ground pile structure for fixing a container-type energy storage device, comprising two connection beams, a plurality of cross beams fixedly connected between the two connection beams, the plurality of cross beams being sequentially distributed along the length of the connection beams, two sets of connection structures symmetrically connected to the bottoms of the two connection beams, two sets of anchor rods fixedly connected to the two connection structures symmetrically, and spiral blades fixedly fitted on the outer circumferential surfaces of the anchor rods; The connecting structure can ensure that the anchor rod is fixedly connected to the bottom of the connecting beam when the anchor rod rotates at different angles.

[0008] Preferably, the two corners of the leading edge of the spiral blade that first contacts the bottom surface are rounded and the chamfer angle of the rounded chamfer is 30 to 45 degrees. The advantage of installing the spiral blade in this manner is that the spiral blade makes it easier to insert the anchor rod spirally into the soil of the ground as it rotates, allowing the anchor rod to be inserted more smoothly into the soil of the ground, reducing the difficulty of the installation work of the ground pile structure and improving the practicality and convenience of the ground pile structure.

[0009] Preferably, the number of spiral blades on the outer periphery of the anchor rod is up to three, and the spiral blades on each anchor rod are equally spaced from top to bottom, with the lowest spiral blade being closest to the top of the anchor rod. The advantage of this arrangement is that the spiral blades do not provide excessive resistance to the anchor rod being inserted into the soil, but improve the tensile strength, pull-out strength and overturning strength of the anchor rod, thereby effectively improving the reliability and stability of the ground pile structure.

[0010] Preferably, the connection structure includes a fixing plate fixedly connected to the bottom of the connection beam by a first bolt, a sleeve fixedly connected to the bottom of the fixing plate, two sets of arc-shaped through-chambers symmetrically formed on the outer periphery of the sleeve, a plurality of through-holes formed from top to bottom on the outer periphery of the anchor rod, the number of through-holes being equal to the number of through-chambers in each set and aligned one-to-one, the connection structure further includes a plurality of second bolts that respectively pass through the plurality of through-holes and the two sets of through-chambers to fix and connect the anchor rod and the sleeve together. The advantage of this installation is that by utilizing the two pairs of arc-shaped through-chambers, as the anchor rod rotates and is inserted into the ground, as long as both ends of the through-hole in the anchor rod are aligned with the two pairs of through-chambers, the anchor rod and the sleeve can be fixed and connected together by the second bolt, which reduces the difficulty of connecting the anchor rod and the connection beam and improves the convenience of the ground pile structure.

[0011] Preferably, the number of through-chambers in each set is at least three, at least two second bolts are fixed when the anchor rod and the sleeve are fixed and connected, and two sets of gaskets are symmetrically connected between the top of the fixing plate and the bottom of the connecting beam, and each set has a plurality of gaskets. The advantage of this installation is that the depth to which the top end of the anchor rod is inserted into the sleeve can be adjusted, and the connecting beam and cross beam can be flexibly adjusted to be level according to the number of each set of gaskets between the fixing plate and the connecting beam. Therefore, after the two sets of anchor rods are fully inserted into the soil, the top ends of the anchor rods do not need to be positioned perfectly on the same plane, which further reduces the difficulty of the installation work of the ground pile structure and greatly improves the convenience and practicality of the ground pile structure.

[0012] Preferably, the connecting beams and cross beams are both I-beams, and a plurality of pairs of support reinforcement plates are fixedly connected to the gaps between the connecting beams and cross beams. The advantage of this arrangement is that it further improves the structural strength of the connecting beams and cross beams, thereby improving the stability and reliability of the ground pile structure. [Effects of the Invention]

[0013] From the above, it can be seen that the present invention has the following technical effects and advantages: 1. In this invention, by utilizing a spiral blade fixedly fitted onto the anchor rod, when inserting the anchor rod into the ground soil, the anchor rod can be rotated downwards to insert the anchor rod quickly and smoothly into the ground soil. This allows the spiral blade to increase the contact area between the anchor rod and the ground soil, effectively improving the tensile strength, pull-out strength and overturning strength of the anchor rod, and effectively improving the stability of the ground pile structure, thereby ensuring the stability of the container-type energy storage device connected to the ground pile structure.

[0014] 2. In this invention, a connecting structure is provided, and the two through-chambers in each pair are arc-shaped. Therefore, when the anchor rod rotates and is inserted into the ground, as long as both ends of the through-hole in the anchor rod are aligned with the two through-chambers in each pair, the anchor rod and sleeve can be fixed and connected together by the second bolt, which reduces the difficulty of connecting the anchor rod and the connecting beam and improves the convenience of the ground pile structure.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention. Needless to say, the described embodiments are not all embodiments, but only some embodiments of the present invention. Any other embodiments that a person skilled in the art can obtain based on the embodiments of the present invention without inventive work fall within the scope of protection of the present invention.

[0018] Referring to the ground pile structure for fixing the container-type energy storage device shown in Figures 1 to 6, it includes two connection beams 1, a plurality of cross beams 2 fixedly connected between the two connection beams 1, the plurality of cross beams 2 being sequentially distributed along the length direction of the connection beam 1, two sets of connection structures 3 symmetrically connected to the bottom of the two connection beams 1, two sets of anchor rods 4 fixedly connected to the two connection structures 3 symmetrically, and spiral blades 6 fixedly fitted onto the outer circumferential surfaces of the anchor rods 4. The connecting structure 3 can ensure that the anchor rod 4 is fixed and connected to the bottom of the connecting beam 1 when the anchor rod 4 rotates at different angles.

[0019] A container-type energy storage device 8 is fixedly connected to the top of the connecting beam 1 and the cross beam 2 by a third bolt. Two sets of first connection plates 11 are fixedly connected symmetrically between the adjacent gaps between the two connection beams 1, and two second connection plates 21 are fixedly connected symmetrically to both the front and rear ends of the cross beam 2, and the multiple cross beams 2 are fixedly connected integrally to the two connection beams 1 by the second connection plates 21, the first connection plates 11 and a fourth screw.

[0020] Referring to Figures 1, 2 and 5, the spiral blade 6 has rounded chamfers 7 at two corners of the leading edge that first contacts the bottom surface, and the chamfer angle of the rounded chamfers 7 is 30 to 45 degrees.

[0021] Specifically, this makes it easier for the spiral blade 6 to be spirally inserted into the soil of the ground as the anchor rod 4 rotates, allowing the anchor rod 4 to be inserted more smoothly into the soil of the ground, reducing the difficulty of the installation work of the ground pile structure and improving the practicality and convenience of the ground pile structure.

[0022] Referring to Figures 1 to 4, the number of spiral blades 6 on the outer peripheral surface of the anchor rod 4 is a maximum of three, and the multiple spiral blades 6 on each anchor rod 4 are distributed at equal intervals from top to bottom, with the lowest spiral blade 6 being close to the apex of the tip of the anchor rod 4.

[0023] Specifically, the spiral blade 6 improves the tensile strength, pull-out strength and overturning strength of the anchor rod 4 without providing excessive resistance to the anchor rod 4 being inserted into the soil of the ground, thereby effectively improving the reliability and stability of the ground pile structure.

[0024] 3 to 6, the connection structure 3 includes a fixed plate 31 fixedly connected to the bottom of the connection beam 1 by a first bolt, a sleeve 32 fixedly connected to the bottom of the fixed plate 31, two sets of arc-shaped through-chambers 33 symmetrically opened on the outer circumferential surface of the sleeve 32, a plurality of through-holes opened from top to bottom on the outer circumferential surface of the anchor rod 4, the number of through-holes is equal to the number of through-chambers 33 in each set and can be aligned one-to-one, the connection structure 3 further includes a plurality of second bolts 34, the plurality of second bolts 34 respectively pass through the plurality of through-holes and the two sets of through-chambers 33 to fix and connect the anchor rod 4 and the sleeve 32 together.

[0025] Specifically, by utilizing the two arc-shaped through-chambers 33 of each pair, if both ends of the through-hole in the anchor rod 4 can be aligned with the two through-chambers 33 of each pair during the process in which the anchor rod 4 rotates and is inserted into the soil of the ground, the anchor rod 4 and the sleeve 32 can be fixed and connected together by the second bolt 34, which reduces the difficulty of connecting the anchor rod 4 and the connecting beam 1 and improves the convenience of the ground pile structure.

[0026] Referring to Figures 4 and 6, the number of through chambers 33 in each set is at least three, at least two second bolts 34 are fixed when the anchor rod 4 and the sleeve 32 are fixed and connected, and two sets of gaskets 35 are symmetrically connected between the top of the fixing plate 31 and the bottom of the connecting beam 1, and the number of gaskets 35 in each set is plural.

[0027] Specifically, the depth to which the top ends of the anchor rods 4 are inserted into the sleeves 32 can be adjusted, and the level of the connecting beams 1 and cross beams 2 can be flexibly adjusted according to the number of each set of gaskets 35 between the fixing plates 31 and the connecting beams 1. As a result, after the two sets of anchor rods 4 are fully inserted into the ground soil, the top ends of the anchor rods 4 do not need to be positioned on the same plane, which further reduces the difficulty of the installation work of the ground pile structure and greatly improves the convenience and practicality of the ground pile structure.

[0028] 1 to 4, the connection beam 1 and the cross beam 2 are both I-beams, and a plurality of pairs of support reinforcing plates 5 are fixed in the gap between the connection beam 1 and the cross beam 2 to connect them.

[0029] Specifically, the structural strength of the connecting beam 1 and the cross beam 2 has been further improved, thereby improving the stability and reliability of the ground pile structure.

[0030] The operating principle is as follows: the two sets of anchor rods 4 are rotated downward one after another until they are inserted to an appropriate depth into the soil of the ground, and then the two sets of sleeves 32 are fitted onto the top ends of the two sets of anchor rods 4, respectively. Next, the insertion depth of the two sets of sleeves 32 of each of the two sets of anchor rods 4 is adjusted so that the heights of the top surfaces of the two sets of fixing plates 31 are as even as possible. Next, the anchor rods 4 and the sleeves 32 are fixed and connected together by the second bolts 34, through holes and through chambers 33.

[0031] Next, the two connecting beams 1 are placed on the top surfaces of the two sets of fixed plates 31, respectively, and at this time the cross beam 2 is already fixed and connected integrally to the connecting beams 1. Next, when the number of gaskets 35 between each fixing plate 31 and the connecting beam 1 causes the two connecting beams 1 to be positioned on the same horizontal plane, the first bolts are used to fix and connect the fixing plates 31 and the connecting beams 1 integrally, thus completing the installation work of the ground pile structure.

[0032] Finally, the container-type power storage device 8 is fixed and connected to the top of the connecting beam 1 and the cross beam 2 by the third bolt, thus completing the fixing and installation work of the container-type power storage device 8.

[0033] Finally, it should be clearly stated that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features thereof, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
