Description
Technical Field
[0001] The utility model relates to the technical field of electronic information engineering, in particular to an anti-interference grounding device for equipment in electronic information engineering. Background Art
[0002] Electronic information engineering refers to the technology of storing and transmitting information electronically, involving multiple fields such as circuits, computers, and communications. In order to avoid leakage and protect the lines during the use of electronic information equipment, there is also a requirement for the use of ground wires. The grounding device is the end point of the ground wire, and the ground wire discharges the current to the earth through the grounding body.
[0003] An anti-interference grounding device for equipment in electronic information engineering with application number 202122662243.X includes a base, a protective shell and a terminal. A mounting plate is fixed above the base, and a photovoltaic mechanism is placed above the mounting plate. A power supply is installed inside the protective shell, and the protective shell is located on the right side of the photovoltaic mechanism. A support foot is provided on the right side of the terminal, and the terminal is located below the base, and a fixing rod is placed below the support foot. The utility model is equipped with a hydraulic rod, and the position of the grounding rod can be adjusted through the operation of the hydraulic rod, so that the device can adjust the length of insertion into the ground according to the situation, thereby improving the flexibility of the device structure, so that the device can be suitable for different occasions, and the scope of application of the device is improved. At the same time, the device avoids the ground loop current through single-point grounding, thereby improving the anti-interference performance of the device from the side.
[0004] This technical solution uses a hydraulic structure to adjust the depth of the grounding body inserted into the ground so as to adapt to different scenarios and improve anti-interference performance. However, it can be seen from the attached drawings of the technical solution that due to the influence of the length of the hydraulic cylinder, the adjustment distance will not be too large, it is difficult to avoid the ground ring current, and the grip performance is weak. If the grounding body is deeply embedded in the soil and is supported by dense soil, gravel, underground parts of buildings and other objects, it is very likely that the entire device will be pushed out of the soil. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide an anti-interference grounding device for equipment in electronic information engineering to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-interference grounding device for equipment in electronic information engineering, comprising an embedded seat and a bracket, wherein ground claws are fixed on both sides of the bottom of the embedded seat, and expansion bolts are penetrated on both sides of the top of the embedded seat, a servo motor is installed on one side of the outer surface of the bracket, and a worm is connected to the output end of the servo motor, a guide column is fixed on the upper part of the bracket, and a grounding body is sleeved on the outside of the guide column, a threaded sleeve is connected to the lower part of the bracket, and a worm gear is sleeved on the outside of the threaded sleeve.
[0007] By adopting the above technical solution, after the servo motor is started, the output end drives the threaded sleeve to rotate through the meshing of the worm and the worm wheel. At the same time, the meshing of the worm and the worm wheel increases the torque and can apply greater force to the threaded sleeve, thereby facilitating the downward movement of the grounding body. After the threaded sleeve rotates, it cooperates with the guide column to guide the grounding body, so that the grounding body moves down or up to adjust the position of the grounding body. The large displacement distance can effectively avoid the ground ring current. At the same time, the inclined expansion bolts and the J-shaped gripping claws effectively increase the gripping force of the embedded seat, thereby effectively avoiding the phenomenon that the grounding body is fixed when it is extended downward, which causes the device to be lifted up.
[0008] Furthermore, the guide post has a square cross section, and the grounding body is slidably connected to the guide post.
[0009] By adopting the above technical solution, since the cross section of the guide column is square, the grounding body can be prevented from rotating along with the threaded sleeve when the guide column is used to guide the grounding body, so that the grounding body can move up or down after the threaded sleeve rotates.
[0010] Furthermore, the outer surface of the grounding body is provided with threads, and the grounding body is threadedly connected to the threaded sleeve.
[0011] By adopting the above technical solution, the threaded sleeve is rotated and cooperates with the guide column to guide the grounding body, so that the grounding body is moved down or up to adjust the position of the grounding body. The large displacement distance can effectively avoid the ground ring current and can be suitable for different scenarios.
[0012] Furthermore, the worm wheel is meshed with the worm.
[0013] By adopting the above technical solution, after the servo motor is started, the output end drives the threaded sleeve to rotate through the meshing of the worm and the worm wheel. At the same time, the meshing of the worm and the worm wheel increases the torque and can apply a greater force to the threaded sleeve, thereby facilitating the downward movement of the grounding body.
[0014] Furthermore, the expansion bolts are arranged obliquely, and the gripping claws are in a "J" shape.
[0015] By adopting the above technical solution, the staff tightens the expansion bolts to make them start to expand. At this time, the inclined expansion bolts and the J-shaped gripping claws effectively increase the gripping force of the embedded seat, thereby effectively avoiding the phenomenon that the grounding body is fixed when extending downward, causing the device to be lifted up.
[0016] Furthermore, a plurality of the expansion bolts and the gripping claws are provided, and the plurality of expansion bolts and the gripping claws are distributed in a ring array.
[0017] By adopting the above technical solution, the number of expansion bolts and gripping claws is increased, thereby increasing the contact area between the expansion bolts and the gripping claws and the ground, and further increasing the gripping force.
[0018] Furthermore, the bracket is connected to the top of the embedded seat, and a wire sliding groove is provided on the outer surface of the bracket.
[0019] By adopting the above technical solution, first, the staff digs a hole on the ground. After digging the hole, the staff evenly sprinkles the grounding resistance reducing agent in the hole to reduce the grounding resistance, so as to better utilize the grounding structure to discharge the current to the earth. Then the staff puts the embedded seat into the hole and backfills the soil to the bottom of the embedded seat.
[0020] Furthermore, a brush cylinder is connected to the bottom of the embedded seat, and the grounding body is slidably connected to the brush cylinder.
[0021] By adopting the above technical solution, the surface of the grounding body is cleaned by the brush tube while the grounding body moves upward, thereby reducing the adhesion of soil particles.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] 1. The utility model is provided with a servo motor, a grounding body, a guide column, a worm, a threaded sleeve and a worm wheel. After the servo motor is started, the output end drives the threaded sleeve to rotate through the meshing of the worm and the worm wheel. At the same time, the meshing of the worm and the worm wheel increases the torque and can apply a greater force to the threaded sleeve, thereby facilitating the downward movement of the grounding body. After the threaded sleeve rotates, it cooperates with the guide column to guide the grounding body, so that the grounding body moves downward or upward to adjust the position of the grounding body. The large displacement distance can effectively avoid the ground loop current; and the anti-interference performance is increased;
[0024] 2. The utility model effectively increases the gripping force of the embedded seat through the arrangement of the embedded seat, expansion bolts and gripping claws, and through the inclined expansion bolts and J-shaped gripping claws, thereby effectively avoiding the phenomenon that the grounding body is fixed when extending downward, which causes the device to be lifted up; and improves the stability of the device.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The following describes an embodiment of the utility model based on its overall structure.
[0032] Embodiment 1:
[0033] An anti-interference grounding device for equipment in electronic information engineering, such as Figure 1-Figure 4 As shown, it includes an embedded seat 1 and a bracket 2, both sides of the bottom of the embedded seat 1 are fixed with gripping claws 6, the gripping claws 6 are in a "J" shape, and both sides of the top of the embedded seat 1 are penetrated with expansion bolts 5, the expansion bolts 5 are arranged obliquely, and multiple expansion bolts 5 and gripping claws 6 are arranged, and multiple expansion bolts 5 and gripping claws 6 are distributed in a ring array. The inclined expansion bolts 5 and the J-shaped gripping claws 6 effectively increase the gripping force of the embedded seat 1, thereby effectively avoiding the phenomenon that the grounding body 8 is fixed when it extends downward, causing the device to be lifted up instead;
[0034] A servo motor 7 is installed on one side of the outer surface of the bracket 2, and a worm 10 is connected to the output end of the servo motor 7. A guide column 9 is fixed on the upper part of the inside of the bracket 2. The cross-section of the guide column 9 is square. A grounding body 8 is sleeved on the outside of the guide column 9. The grounding body 8 is slidably connected to the guide column 9. A threaded sleeve 11 is connected to the lower part of the inside of the bracket 2. The outer surface of the grounding body 8 is provided with threads. The grounding body 8 is threadedly connected to the threaded sleeve 11. A worm wheel 12 is sleeved on the outside of the threaded sleeve 11, and the worm wheel 12 is meshed with the worm 10. After the servo motor 7 is started, the output end drives the threaded sleeve 11 to rotate through the meshing of the worm 10 and the worm wheel 12. At the same time, the meshing of the worm 10 and the worm wheel 12 increases the torque and can apply a greater force to the threaded sleeve 11, thereby facilitating the downward movement of the grounding body 8. After the threaded sleeve 11 rotates, it cooperates with the guide column 9 to guide the grounding body 8, so that the grounding body 8 moves down or up to adjust the position of the grounding body 8.
[0035] See also Figure 1-Figure 4In the above embodiment, the bracket 2 is connected to the top of the embedded seat 1, and the staff digs a hole on the ground. After digging the hole, the staff evenly sprinkles the grounding resistance reducing agent in the hole to reduce the grounding resistance, so as to better utilize the grounding structure to discharge the current to the earth. Then the staff puts the embedded seat 1 into the hole and backfills the soil to the bottom of the embedded seat 1; a sliding wire groove 3 is opened on the outer surface of the bracket 2, and the grounding wire moves up and down in the sliding wire groove 3 following the up and down displacement of the grounding body 8.
[0036] Embodiment 2:
[0037] On the basis of the above-mentioned embodiment 1, although the anti-interference performance can be increased by setting the servo motor 7, the grounding body 8, the guide column 9, the worm 10, the threaded sleeve 11 and the worm wheel 12; however, the mud can easily cover the surface of the grounding body 8 and affect its displacement; now, by setting the brush cylinder 4, the surface of the grounding body 8 can be cleaned.
[0038] See also Figure 2-Figure 4 In the above embodiment, a brush cylinder 4 is connected to the bottom of the embedded seat 1, and the grounding body 8 is slidably connected to the brush cylinder 4. When the grounding body 8 moves upward, the surface of the grounding body 8 is cleaned by the brush cylinder 4 to reduce the adhesion of soil particles.
[0039] The implementation principle of the utility model is as follows: first, the staff digs a hole on the ground. After the hole is dug, the staff evenly sprinkles the grounding resistance reducing agent in the hole to reduce the grounding resistance, so as to better utilize the grounding structure to discharge the current to the earth. Then the staff puts the embedded seat 1 into the hole and backfills the soil to the bottom of the embedded seat 1, and only the top of the expansion bolt 5 needs to leak out. Then the staff tightens the expansion bolt 5 to make the expansion bolt 5 start to expand. At this time, the inclined expansion bolt 5 and the J-shaped gripping claw 6 effectively increase the gripping force of the embedded seat 1, thereby effectively avoiding the phenomenon that the grounding body 8 is fixed when it is extended downward, causing the device to be lifted up. Then the staff passes the grounding wire through the sliding wire groove 3 to connect it to the grounding body 8;
[0040] After the servo motor 7 is started, the output end drives the threaded sleeve 11 to rotate through the meshing of the worm 10 and the worm wheel 12. At the same time, the meshing of the worm 10 and the worm wheel 12 increases the torque and can apply a greater force to the threaded sleeve 11, thereby facilitating the downward movement of the grounding body 8. After the threaded sleeve 11 rotates, it cooperates with the guide column 9 to guide the grounding body 8, so that the grounding body 8 moves down or up to adjust the position of the grounding body 8. The large displacement distance can effectively avoid the ground ring current and can be applied to different scenes. At the same time, the grounding wire moves up and down in the sliding wire groove 3 following the up and down displacement of the grounding body 8, and when the grounding body 8 moves up, the brush cylinder 4 cleans the surface of the grounding body 8 to reduce the adhesion of soil particles.
[0041] It should be noted that if the device is used outdoors, a shield should be set around the servo motor 7 to prevent rain from invading and affecting the servo motor 7. If it is used indoors, such as in underground distribution rooms, underground garages and other places, there is no need to set up a shield.
