Description

Technical Field

[0001] The invention belongs to the technical field of grounding devices, and in particular relates to a grounding device for ensuring the safety of electricity use. Background Art

[0002] Grounding device refers to the grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment, also known as grounding integrated device. It mainly consists of grounding electrode (plate), grounding busbar (indoor, outdoor), grounding down conductor (grounding jumper wire), frame grounding and other parts. The main function of grounding device is to connect the metal casing or other conductor of electrical equipment to the earth to form an electrical circuit, so as to maintain the balance and stability of the electric potential.

[0003] In some high-power electrical equipment made of metal casings, grounding equipment is the key to ensuring that the equipment casing does not leak electricity. However, when faced with some movable high-power electrical equipment used outdoors, in order to ensure its grounding effect, a mobile grounding device is used. However, this grounding device is more complicated to deploy and cannot be installed and used quickly. At the same time, it requires external excavation equipment to plug the conductive column into the ground, and its efficiency is low.

[0004] At the same time, after the installation of the grounding device is completed, the grounding device needs to be connected to the casing of the electrical equipment through conductive devices such as conductive sheets or conductive wires. This connection method takes a long time to complete, and it also takes a long time to disassemble when removing the grounding device. It is impossible to achieve rapid disassembly and assembly with the electrical equipment, and improvement is urgently needed. Summary of the invention

[0005] The purpose of the present invention is to provide a grounding device for ensuring the safety of electricity use, so as to solve the problems raised in the above-mentioned background technology.

[0006] The cam is secured to a position 400 feet high and has a first end fixed to the side panel that is located adjacent to the first support bracket, the second end being secured to a position 500 feet high and having a first end being secured to a position adjacent to the first support bracket.

[0007] Before using the device, it is necessary to place the device near external electrical equipment. At this time, the device is in the storage state. If the device needs to be used, the entire grounding assembly can be pressed downward. At this time, the grounding assembly can be moved downward relative to the fixed plate. At the same time, the grounding assembly can synchronously drive the movable plate to move downward when it moves downward. At this time, the distance between the fixed plate and the movable plate increases accordingly. At the same time, the second fixed seat moves downward, and the connecting rod on the outer side of the second fixed seat is driven to deflect toward the outer side, that is, from a vertical state to a horizontal state. At this time, the support rod can be subjected to the thrust from the connecting rod, and rotates relative to the fixed plate through the first fixed seat, and changes from the storage state to the unfolded state. After the unfolding is completed, the device can be supported by the supporting feet at the bottom of the support rod;

[0008] When the device is not needed, the grounding assembly can be pulled upward to drive the movable plate to move upward until the connecting rod is deflected in the vertical direction and the support rod is pulled to rotate inward, finally completing the inward retraction of multiple support rods and completing the storage process.

[0009] By providing a plurality of movable support rods and cooperating with the function of the grounding component, the device can be quickly unfolded by pressing the grounding component downward, and the device can be quickly stored by pulling up the grounding component to complete the folding process. The whole process is completed quickly, and the device can be quickly unfolded and stored, thereby improving the use efficiency of the device.

[0010] As a further technical solution of the present invention, the grounding assembly includes a movable sleeve, the outer side surface of the movable sleeve is movably connected to the fixed plate, the outer side surface of the movable sleeve is fixedly connected to the movable plate, the middle part of the movable sleeve is movably connected to a conductive rod, and the bottom end of the conductive rod passes through the bottom end of the movable sleeve.

[0011] As a further technical solution of the present invention, a limiting sleeve is fixedly installed on the top of the movable sleeve, a mounting plate is fixedly installed on the top of the conductive rod, and a magnet located above the limiting sleeve is fixedly installed on the bottom of the mounting plate.

[0012] As a further technical solution of the present invention, a limit ring is fixedly sleeved on the inner cavity of the movable sleeve near the bottom end, a limit plate located inside the movable sleeve is fixedly installed on the outer side of the conductive rod near the bottom end, and a limit spring is movably sleeved on the outer side of the conductive rod.

[0013] As a further technical solution of the present invention, the upper and lower ends of the limit spring are respectively connected to the bottom end of the limit plate and the top end of the limit ring. When the magnet and the limit sleeve are adsorbed on each other, the limit spring is in a compressed state. When the limit spring is in an initial state, the magnet and the limit sleeve are not adsorbed on each other.

[0014] When the device is being deployed, the limit sleeve can be pressed downward, which can drive the movable sleeve and the conductive rod to move downward synchronously, and drive the movable plate to move downward. As the limit sleeve moves further downward, the bottom end of the movable sleeve is inserted into the ground surface. When the plug-in is completed, the device can be deployed synchronously. At this time, the mounting plate can be pressed downward, so that the conductive rod moves downward relative to the movable sleeve. At this time, the conductive rod protrudes from the bottom end of the movable sleeve and is inserted into the soil through the bottom end of the movable sleeve to complete the grounding process.

[0015] At the same time, when the device is reset, the adsorption between the magnet and the limit sleeve can be released by pulling the mounting plate upwards, and the limit spring can be automatically reset, and finally the conductive rod can be automatically raised, so that the conductive rod is completely retracted into the interior of the movable sleeve, and the device can be pulled out of the soil by pulling the movable sleeve upwards, and the storage is automatically completed.

[0016] By utilizing the unfolding process of the device, the device only needs to press down the grounding component to quickly realize the unfolding and grounding process of the device. The two processes are completed at the same time, which effectively avoids the traditional device that needs to be carried out step by step and also requires the use of external excavation equipment to realize the grounding process, effectively shortens the preliminary preparation time, and improves the disassembly and assembly efficiency of the device, thereby improving work efficiency.

[0017] As a further technical solution of the present invention, the external component includes an extended guide rail, one side of the extended guide rail is connected to the outer side surface of the limit sleeve, the internal movable clamp of the extended guide rail is connected with a guide block, the guide block is connected to the conductive rod through a wire, and the end of the guide block away from the limit sleeve is fixedly connected with an adjustable telescopic rod.

[0018] As a further technical solution of the present invention, the adjustable end of the adjustable telescopic rod passes through one side of the extended guide rail and is fixedly connected with a contact pole, and the contact pole is in contact with the external electrical equipment.

[0019] As a further technical solution of the present invention, a fourth fixed seat is fixedly installed on the top of the guide block, and the end of the fourth fixed seat away from the guide block is movably connected to an adjusting rod via a rotating shaft, and the end of the adjusting rod away from the fourth fixed seat is movably connected to a fifth fixed seat via a rotating shaft, and the end of the fifth fixed seat away from the adjusting rod is connected to the outer side surface of the mounting plate.

[0020] As a further technical solution of the present invention, when the magnet is not adsorbed to the limiting sleeve, the mounting plate is at the highest point, and the distance that the contact pole protrudes out of the extended guide rail is the minimum.

[0021] When the device is deployed and grounded, the downward movement of the limit sleeve can synchronously drive the extended guide rail to move downward. When the grounding operation is performed, that is, the mounting plate moves downward, the fifth fixing seat can be driven to move downward. At the same time, the adjusting rod is deflected and drives the guide block to move in the direction away from the limit sleeve. At this time, the adjustable telescopic rod and the contact pole can be pushed to move in the direction away from the device. By adjusting the length of the adjustable telescopic rod, the contact pole just contacts with the casing of the electrical equipment after the plugging is completed, and the grounding operation of the casing of the electrical equipment can be completed, and the overlapping process is completed.

[0022] By reusing the unfolding and grounding process of the device, the device can simultaneously achieve overlap with the casing of the external electrical equipment during the unfolding and grounding process. The entire process is completed automatically, so that the device can quickly achieve grounding of the external electrical equipment and achieve safe use of electricity in a single step. At the same time, during disassembly, it only takes one step to achieve rapid disassembly and assembly, further improving the working efficiency of the device.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention utilizes the unfolding process of the device so that the device can quickly realize the unfolding and grounding process of the device only by pressing the grounding component downward. The two processes are completed at the same time, which effectively avoids the need for traditional devices to be carried out step by step. At the same time, external excavation equipment is also required to realize the grounding process, which effectively shortens the preliminary preparation time, improves the disassembly and assembly efficiency of the device, and improves work efficiency.

[0025] 2. The present invention is provided with a plurality of movable support rods, and cooperates with the function of the grounding component, so that the device can be quickly unfolded by pressing the grounding component downward, and the device can be quickly stored by pulling up the grounding component to complete the folding process.

[0026] 3. The present invention reuses the unfolding and grounding process of the device, so that the device can simultaneously achieve overlap with the casing of the external electrical equipment during the unfolding and grounding process. The entire process is completed automatically, so that the device can quickly achieve grounding of the external electrical equipment and achieve safe use of electricity with only a single step. At the same time, when disassembling, it only takes one step to achieve rapid disassembly and assembly, further improving the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the distance between the fixed plate 1 and the movable plate 5 increases accordingly. At the same time, the second fixing seat 6 moves downward, and drives the connecting rod 7 on the outer side of the second fixing seat 6 to deflect toward the outer side, that is, from a partially vertical state to a partially horizontal state. At this time, the support rod 3 can be subjected to the thrust from the connecting rod 7, and rotates relative to the fixed plate 1 through the first fixing seat 2, and changes from the storage state to the unfolded state. After the unfolding is completed, the device can be supported by the supporting foot 4 at the bottom of the support rod 3;

[0038] When the device is not needed, the grounding assembly 9 can be pulled upward to drive the movable plate 5 to move upward until the connecting rod 7 is deflected in the vertical direction and the support rod 3 is pulled to rotate toward the inner side, and finally the multiple support rods 3 are retracted inwardly to complete the storage process.

[0039] By providing a plurality of movable support rods 3 and cooperating with the function of the grounding component 9, the device can be quickly unfolded by pressing the grounding component 9 downward, and the device can be quickly stored by pulling up the grounding component 9 to complete the folding process. The whole process is completed quickly, and the device can be quickly unfolded and stored, thereby improving the use efficiency of the device.

[0040] like Figure 1 and Figure 3 and Figure 4 as well as Figure 5As shown, the grounding assembly 9 includes a movable sleeve 901, the outer side of the movable sleeve 901 is movably sleeved with the fixed plate 1, the outer side of the movable sleeve 901 is fixedly sleeved with the movable plate 5, the middle part of the movable sleeve 901 is movably sleeved with a conductive rod 904, the bottom end of the conductive rod 904 passes through the bottom end of the movable sleeve 901, the top of the movable sleeve 901 is fixedly installed with a limiting sleeve 902, the top of the conductive rod 904 is fixedly installed with a mounting plate 905, the bottom end of the mounting plate 905 is fixedly installed with a magnet 906 located above the limiting sleeve 902, and the inner part of the movable sleeve 901 is fixedly installed with a conductive rod 904.

[0041] Embodiment: When the device is unfolded, the limiting sleeve 902 can be pressed downward, and the movable sleeve 901 and the conductive rod 904 can be driven to move downward synchronously, and the movable plate 5 can be driven to move downward. As the limiting sleeve 902 moves further downward, the bottom end of the movable sleeve 901 is inserted into the ground surface. When the plugging is completed, the device can be unfolded synchronously. At this time, the mounting plate 905 can be pressed downward, so that the conductive rod 904 moves downward relative to the movable sleeve 901. At this time, the conductive rod 904 protrudes from the bottom end of the movable sleeve 901 and is inserted into the soil through the bottom end of the movable sleeve 901 to complete the grounding process.

[0042] At the same time, when the device is reset, the adsorption between the magnet 906 and the limit sleeve 902 can be released by pulling the mounting plate 905 upwards, and the limit spring 908 can be automatically reset, and finally the conductive rod 904 can be automatically raised, so that the conductive rod 904 is completely retracted into the interior of the movable sleeve 901, and the device can be pulled out of the soil by pulling the movable sleeve 901 upwards, and the storage is automatically completed.

[0043] By utilizing the unfolding process of the device, the device only needs to press down the grounding component 9 to quickly realize the unfolding and grounding process of the device. The two processes are completed at the same time, which effectively avoids the need for traditional devices to be carried out step by step. At the same time, external excavation equipment is also required to realize the grounding process, which effectively shortens the preliminary preparation time, improves the disassembly and assembly efficiency of the device, and improves work efficiency.

[0044] like Figure 1 and Figure 2As shown, the external assembly 10 includes an extended guide rail 101, one side of the extended guide rail 101 is connected to the outer side of the limit sleeve 902, the inner part of the extended guide rail 101 is movably connected with a guide block 102, the guide block 102 is connected to the conductive rod 904 through a wire, and the end of the guide block 102 away from the limit sleeve 902 is fixedly connected to an adjustable telescopic rod 105, the adjustable end of the adjustable telescopic rod 105 passes through one side of the extended guide rail 101 and is fixedly connected to a contact pole 106, the contact pole 106 is in contact with the external electrical equipment, and the guide block 10 2 is fixedly installed with a fourth fixing seat 103 at the top, and an end of the fourth fixing seat 103 away from the guide block 102 is movably connected to an adjusting rod 107 through a rotating shaft, and an end of the adjusting rod 107 away from the fourth fixing seat 103 is movably connected to a fifth fixing seat 104 through a rotating shaft, and an end of the fifth fixing seat 104 away from the adjusting rod 107 is connected to the outer side surface of the mounting plate 905. When the magnet 906 is not adsorbed to the limiting sleeve 902, the mounting plate 905 is at the highest point, and the distance that the contact pole 106 protrudes from the extended guide rail 101 is the minimum value.

[0045] Embodiment: When the device is unfolded and grounded, the downward movement of the limit sleeve 902 can synchronously drive the extended guide rail 101 to move downward. When the grounding operation is performed, that is, the mounting plate 905 moves downward, the fifth fixing seat 104 can be driven to move downward. At the same time, the adjustment rod 107 deflects and drives the guide block 102 to move away from the limit sleeve 902. At this time, the adjustable telescopic rod 105 and the contact pole 106 can be pushed to move away from the device. By adjusting the length of the adjustable telescopic rod 105, the contact pole 106 is just in contact with the casing of the electrical equipment after the plugging is completed, and the grounding operation of the casing of the electrical equipment can be completed, and the overlapping process is completed.

[0046] By reusing the unfolding and grounding process of the device, the device can simultaneously achieve overlap with the casing of the external electrical equipment during the unfolding and grounding process. The entire process is completed automatically, so that the device can quickly achieve grounding of the external electrical equipment and achieve safe use of electricity in a single step. At the same time, during disassembly, it only takes one step to achieve rapid disassembly and assembly, further improving the working efficiency of the device.

[0047] Working principle and usage process:

[0048] When the device is being deployed, the limiting sleeve 902 can be pressed downward, which can drive the movable sleeve 901 and the conductive rod 904 to move downward synchronously, and drive the movable plate 5 to move downward. As the limiting sleeve 902 moves further downward, the bottom end of the movable sleeve 901 is inserted into the ground surface. When the plugging is completed, the device can be deployed synchronously. At this time, the mounting plate 905 can be pressed downward, so that the conductive rod 904 moves downward relative to the movable sleeve 901. At this time, the conductive rod 904 protrudes from the bottom end of the movable sleeve 901 and is inserted into the soil through the bottom end of the movable sleeve 901, completing the grounding process.

[0049] Before using the device, it is necessary to place the device near external electrical equipment. At this time, the device is in the storage state. If the device needs to be used, the entire grounding component 9 can be pressed downward. At this time, the grounding component 9 can be moved downward relative to the fixed plate 1. At the same time, when the grounding component 9 moves downward, it can synchronously drive the movable plate 5 to move downward. At this time, the distance between the fixed plate 1 and the movable plate 5 increases accordingly. At the same time, the second fixing seat 6 moves downward, and drives the connecting rod 7 on the outer side of the second fixing seat 6 to deflect toward the outer side, that is, from a partially vertical state to a partially horizontal state. At this time, the support rod 3 can be subjected to the thrust from the connecting rod 7, and rotates relative to the fixed plate 1 through the first fixing seat 2, and changes from the storage state to the unfolded state. After the unfolding is completed, the device can be supported by the supporting foot 4 at the bottom of the support rod 3;

[0050] When the device is unfolded and grounded, the downward movement of the limit sleeve 902 can synchronously drive the extension guide rail 101 to move downward. When the grounding operation is performed, that is, the mounting plate 905 moves downward, the fifth fixing seat 104 can be driven to move downward, and the adjustment rod 107 deflects accordingly, and drives the guide block 102 to move in a direction away from the limit sleeve 902. At this time, the adjustable telescopic rod 105 and the contact pole 106 can be pushed to move in a direction away from the device, and by adjusting the length of the adjustable telescopic rod 105, the contact pole 106 is just in contact with the shell of the electrical equipment after the plugging is completed, so that the grounding operation of the shell of the electrical equipment can be completed, and the overlapping process is completed;

[0051] At the same time, when the device is reset, the adsorption between the magnet 906 and the limit sleeve 902 can be released by pulling the mounting plate 905 upwards, and the limit spring 908 can be automatically reset, and finally the conductive rod 904 can be automatically raised, so that the conductive rod 904 is completely retracted into the inside of the movable sleeve 901, and the device can be pulled out of the soil by pulling the movable sleeve 901 upwards, and the storage is automatically completed;

[0052] When the device is not needed, the grounding assembly 9 can be pulled upward to drive the movable plate 5 to move upward until the connecting rod 7 is deflected in the vertical direction and the support rod 3 is pulled to rotate toward the inner side, and finally the multiple support rods 3 are retracted inwardly to complete the storage process.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
