Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of electric power construction, and in particular relates to a grounding pin installation system. Background Art
[0002] The main function of the grounding pin is to reliably ground the power equipment, prevent electric shock accidents caused by electrical faults, and ensure the safety of personnel and equipment. Conventional grounding pins are usually conical structures. The tip design of the conical structure makes it easy to insert into the soil. In addition, the grounding pin is usually driven into the ground by knocking, but the knocking force is difficult to control, which can easily cause the grounding pin to bend or damage. Especially when the soil is hard or there are stones in the soil, it is very easy to damage the grounding pin by knocking directly and vigorously. Even if the grounding pin is not damaged, it is difficult to knock it to the specified depth, affecting the grounding effect. In the case of soft soil, after the grounding pin is inserted into the soil, the connection between it and the soil is not tight, and there is a gap, which makes the grounding pin unable to remain stable and affects the grounding effect. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides a grounding pin installation system to solve the problem that when the soil is hard or there are stones in the soil, the grounding pin is easily damaged by directly hitting it with great force. Even if the grounding pin is not damaged, it is difficult to knock it to a specified depth. When the soil is relatively soft, after the grounding pin is inserted into the soil, the connection between the grounding pin and the soil is not tight, and there is a gap, which makes the grounding pin unable to remain stable. Both of the above situations will affect the grounding effect.
[0004] According to an embodiment of the present invention, the present invention adopts the following technical solution:
[0005] The invention discloses a grounding needle installation system, comprising a needle body and a driving mechanism for driving the needle body to be inserted into the soil, wherein the outer wall of the needle body is provided with a thread; the driving mechanism comprises a bracket, a mounting plate slidably connected to the bracket in a vertical direction, a swivel rotatably connected to the mounting plate, and a connecting rod fixed in the swivel, and the needle body is detachably connected to the lower end of the connecting rod; a first channel and a second channel are provided in the needle body, wherein the first channel is used for introducing a soil softener, a first outlet connected to the first channel is provided at the free end of the needle body, and the second channel is used for introducing a conductive gel, a plurality of second outlets connected to the second channel are provided along the axial direction of the needle body side wall, and a stopper is slidably connected to the first outlet and the second outlet, and the stopper comprises an inserting portion inserted into the first outlet or the second outlet and a limiting portion fixed on the inserting portion, and an embedding groove for embedding the limiting portion is provided on the outer wall of the needle body.
[0006] Compared with the prior art, the present invention has the following beneficial effects:
[0007] 1. A thread is set on the outer wall of the needle body. By rotating the swivel and sliding the mounting plate downward, the needle body can be driven to move downward while rotating, so that the needle body is screwed into the soil. Compared with directly knocking the needle body vertically into the soil, the vertical force on the needle body is reduced, thereby reducing the bending or damage of the needle body.
[0008] 2. According to the judgment of soil hardness, when the soil hardness is relatively high, soil softener can be introduced through the first channel, and the soil softener is discharged into the soil from the first outlet located at the free end of the needle body, which makes it easier for the free end of the needle body to continue to rotate downward. When the soil is relatively soft, conductive gel is introduced through the second channel, and the conductive gel is discharged into the soil from the second outlet located on the side wall of the needle body, and can penetrate into the soil near the needle body along the axial direction of the needle body, increase the viscosity of the needle body and the soil, and enhance the conductive effect.
[0009] In this solution, according to the actual soil hardness, it can be selected whether to introduce soil softener or conductive gel into the first channel or the second channel to reduce material waste. Only the first channel, the second channel, the first outlet and the second outlet need to be opened in the needle body to transmit the soil softener or the conductive gel, which makes the processing of the needle body more convenient.
[0010] In addition, by setting the stopper, when the needle body enters the soil, it can be prevented that the soil enters the needle body through the first outlet or the second outlet.
[0011] Furthermore, a gear is fixed on the outside of the rotating ring, and the driving mechanism also includes a rack slidably connected to the mounting plate, and the rack and the gear are meshed for transmission.
[0012] Furthermore, a first detection member for detecting a sliding speed of the mounting plate is mounted on the bracket.
[0013] Furthermore, a mounting ring is fixed on the connecting rod, and a first box body for communicating with the first channel and a second box body for communicating with the second channel are installed on the mounting ring. The first box body is used to store soil softener, and the second box body is used to store conductive gel.
[0014] Furthermore, a first piston is vertically slidably connected in the first box body, a first connecting hole for connecting with the first channel is opened on the first box body, a first valve is installed in the first connecting hole, a first connecting hole is connected to a first hose for inserting into the first channel, and the first hose extends to the bottom of the first channel.
[0015] Furthermore, a second piston is vertically slidably connected in the second box body, a second connecting hole for connecting with the second channel is opened on the second box body, a second valve is installed in the second connecting hole, a second connecting hole is connected with a second hose for inserting into the second channel, and the second hose extends to the upper part of the second channel.
[0016] Furthermore, it also includes a controller, wherein a signal receiving end of the controller is used to receive a detection signal from the first detection member, and a signal output end of the controller is used to control the amount of soil softener entering the first channel from the first box or to control the amount of conductive gel entering the second channel from the second box.
[0017] Furthermore, a driving member for driving the mounting plate to slide is installed on the bracket, and the signal output end of the controller is also used to control the power output of the driving member.
[0018] Furthermore, magnetic blocks that attract each other are installed in the limiting portion and the embedding groove.

DETAILED DESCRIPTION
[0025] The present invention is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.
[0026] like Figure 1 As shown, the grounding needle installation system includes a needle body 13 and a driving mechanism for driving the needle body 13 to be inserted into the soil. The lower end of the needle body 13 is provided with a conical tip to facilitate the needle body 13 to enter the soil. The outer wall of the needle body 13 is provided with a thread. Through the setting of the thread, the needle body 13 can be screwed into the soil by rotating the needle body 13, which is more convenient for the needle body 13 to enter the soil. In order to facilitate the judgment of the depth of the needle body 13 entering the soil, the outer wall of the needle body 13 is provided with scale lines along its axial direction.
[0027] The driving mechanism includes a bracket 1, a mounting plate 2 vertically slidably connected to the bracket 1, a swivel 5 rotatably connected to the mounting plate 2, and a connecting rod 6 fixed in the swivel 5. The needle body 13 is detachably connected to the lower end of the connecting rod 6. Specifically, the needle body 13 and the connecting rod 6 can be connected by a flange or other detachable methods in the prior art. After the needle body 13 is inserted into the soil to a specified depth, the connection can be released. A driving member for driving the mounting plate 2 to slide is installed on the bracket 1. The driving member includes a first cylinder fixed on the bracket 1. A gear 3 is fixed on the outer side of the swivel 5. The driving mechanism also includes a rack 4 slidably connected to the mounting plate 2. The rack 4 and the gear 3 are meshed for transmission. A second cylinder for driving the rack 4 to slide is installed on the mounting plate 2. When the rack 4 is driven to slide, the rack 4 drives the gear 3 to rotate, thereby driving the needle body 13 to rotate, synchronously driving the mounting plate 2 to slide down, and cooperating with the downward movement of the needle body 13, so that the needle body 13 moves downward during the rotation process and is screwed into the soil.
[0028] The first cylinder and the second cylinder both use the change in air pressure as power when outputting power. When the soil hardness is relatively large, resulting in a large resistance to the needle body 13 entering the soil, the force required to push the mounting plate 2 downward is also large. Under the premise that the first cylinder maintains a constant power output, it is easy for the needle body 13 to only perform a rotational motion, but not to rotate downward or to rotate downward at a slow speed. Correspondingly, when the soil is relatively soft, the needle body 13 can easily enter the soil, and the force required to push the mounting plate 2 downward is also small. Therefore, according to the sliding speed of the mounting plate 2, the soil hardness can be judged to a certain extent. To this end, in the embodiment, a first detection member for detecting the sliding speed of the mounting plate 2 is installed on the bracket 1. Specifically, the first detection member can use a laser speed meter installed on the bracket 1 to obtain the movement speed of the mounting plate 2.
[0029] The first cylinder uses the change in air pressure as its power. Even if the mounting plate 2 cannot be pushed down, the air pressure in the first cylinder can serve as a buffer, and no strong force will be applied to push the needle 13, causing damage. This allows a certain amount of time for the staff to deal with the problem. During the actual design process, an air pressure sensor can also be installed in the first cylinder. When the air pressure in the first cylinder changes continuously, it means that there is a problem in pushing the mounting plate 2 down, reminding the staff to deal with it quickly.
[0030] Combination Figure 2As shown, the needle body 13 is provided with a first channel 15 and a second channel 16. The first channel 15 is used to introduce soil softener. The free end of the needle body 13 is provided with a first outlet 17 connected to the first channel 15. The soil softener is discharged into the soil from the first outlet 17 located at the free end of the needle body 13, which makes it easier for the free end of the needle body 13 to continue to rotate downward. The second channel 16 is used to introduce conductive gel. The side wall of the needle body 13 is provided with a plurality of second outlets 21 connected to the second channel 16 along its axial direction. The conductive gel is discharged into the soil from the second outlets 21 located on the side wall of the needle body 13, and can penetrate into the soil near the needle body 13 along the axial direction of the needle body 13, thereby increasing the viscosity between the needle body 13 and the soil and enhancing the conductive effect.
[0031] Combination Figure 3 As shown, in the process of the needle body 13 entering the soil, in order to prevent the soil from entering the needle body 13 through the first outlet 17 or the second outlet 21, a stopper 20 is slidably connected in the first outlet 17 and the second outlet 21. The stopper 20 includes an insertion portion 19 inserted into the first outlet 17 or the second outlet 21 and a limiting portion 18 fixed on the insertion portion 19. The outer wall of the needle body 13 is provided with an embedding groove 22 for the limiting portion 18 to be embedded. Through the design of the embedding groove 22, the limiting portion 18 can be prevented from hindering the needle body 13 from entering the soil. In order to prevent the stopper 20 from falling during transportation or the needle body 13 entering the soil, mutually attractive magnetic blocks are installed in the limiting portion 18 and the embedding groove 22. Through the magnetic attraction, the stopper 20 is fixed in the first outlet 17 or the second outlet 21 to a certain extent. In order to facilitate pushing the block 20 out of the first outlet 17 or the second outlet 21 when needed, a pointed end is provided on the side of the limiting portion 18 facing away from the needle body 13, and in the actual design process, the thickness of the limiting portion 18 is designed to be as small as possible, and the insertion portion 19 is conical or truncated cone-shaped with the small diameter end facing the inside of the needle body 13. The inclined side wall of the insertion portion 19 can guide the soil softener or conductive gel, and is also easier to be pushed. The block 20 only needs to move a small distance into the soil to open the first outlet 17 or the second outlet 21, and it is not necessary to completely push the block 20 out of the first outlet 17 or the second outlet 21.
[0032] The connecting rod 6 is fixed with a mounting ring 7, and the mounting ring 7 is provided with a first box 11 for communicating with the first channel 15 and a second box 8 for communicating with the second channel 16. The first box 11 is used to store a soil softener, and the soil softener can be directly selected from liquid softeners in the prior art, or powdered softeners can be selected and dissolved for use. If conditions do not permit, water can be directly selected to soak the soil, thereby softening the soil to a certain extent. The second box 8 is used to store a conductive gel, and the conductive gel can be a conductive glue in the prior art.
[0033] A first piston 12 is vertically slidably connected in the first box body 11, a first communication hole for communicating with the first channel 15 is opened on the first box body 11, a first valve is installed in the first communication hole, and a first hose 14 for inserting into the first channel 15 is connected to the first communication hole. Figure 4 As shown, the first hose 14 extends to the bottom of the first channel 15. A third cylinder for driving the first piston 12 to slide is installed in the first box 11. The first piston 12 slides to push the soil softener in the first box 11 from the first connecting hole into the first hose 14, and then extends to the bottom of the first channel 15 and is discharged into the soil from the first outlet 17. Through the design of the first hose 14, the soil softener does not actually pass through the first channel 15. After the soil hardness meets the requirement for the needle body 13 to be screwed in, the soil softener remaining in the first hose 14 can be withdrawn by sliding the first piston 12 in the reverse direction, so as to avoid the soil softener remaining in the first channel 15 from seeping into the soil for a long time, affecting the subsequent installation stability of the needle body 13, and also reducing material waste. In actual use, it is only necessary to insert the first hose 14 into the first channel 15.
[0034] A second piston 9 is vertically slidably connected in the second box body 8, a second connecting hole for connecting with the second channel 16 is opened on the second box body 8, a second valve is installed in the second connecting hole, and a second hose 10 for inserting into the second channel 16 is connected to the second connecting hole. Figure 4 As shown, the second hose 10 extends to the upper part of the second channel 16. A fourth cylinder for driving the second piston 9 to slide is installed in the second box 8. The sliding of the second piston 9 pushes the conductive gel in the second box 8 into the second hose 10 from the second connecting hole, and then into the second channel 16, and is discharged from the second outlet 21 into the soil. After the conductive gel fills the second channel 16, the hydraulic pressure of the conductive gel can push the block 20 in all the second outlets 21 to move, so that the conductive gel is discharged, and the conductive gel fills the second channel 16. After the needle body 13 is installed, the conductive gel remaining in the second channel 16 can also continue to seep out until all the conductive gel is solidified, and the conductive gel in the second channel 16 is connected with the conductive gel that has seeped into the soil, thereby improving the installation stability of the needle body 13 in the soil and improving the conductive performance.
[0035] During specific use, the bracket 1 is placed at the specified position, and the bracket 1 is used as a support to drive the rack 4 to slide and drive the needle body 13 to rotate, and the mounting plate 2 is synchronously driven to slide down, and the needle body 13 moves downward in coordination with the downward movement, so that the needle body 13 moves downward during the rotation process and is screwed into the soil.
[0036] In the above process, the first cylinder is set to maintain a constant power output. When the resistance of the soil is also constant, the movement speed of the mounting plate 2 has a theoretical value. The sliding speed of the mounting plate 2 is detected by the first detection member. When the sliding speed of the mounting plate 2 exceeds the theoretical value, it means that the soil is relatively soft and the resistance to the needle body 13 is small. The more it exceeds the theoretical value, the softer the soil is. After the needle body 13 is screwed into the specified position in the soil, the second piston 9 slides downward. The second piston 9 pushes the conductive gel in the second box 8 into the second hose 10 from the second connecting hole, and then into the second channel 16, and is discharged from the second outlet 21 into the soil. When the conductive gel fills the second channel 16, the hydraulic pressure of the conductive gel pushes the block 20 in all the second outlets 21 to move, so that the conductive gel is discharged. During the process of passing the conductive gel, the mounting plate 2 stops moving and continues to rotate the swivel 5 to rotate the needle body 13, so that the conductive gel can be distributed to the circumference of the needle body 13.
[0037] When the sliding speed of the mounting plate 2 is less than the theoretical value, it means that the soil hardness is relatively large and the resistance to the needle body 13 is relatively large. The smaller the sliding speed of the mounting plate 2 is, the greater the soil hardness is. As the mounting plate 2 continues to slide down, the sliding of the first piston 12 is controlled in real time by detecting the sliding speed of the mounting plate 2. By sliding the first piston 12 downward, the first piston 12 pushes the soil softener in the first box 11 into the first hose 14 from the first connecting hole, and then extends to the bottom of the first channel 15 and is discharged into the soil from the first outlet 17, so that the soil is softened in real time, so that the needle body 13 can be continuously fed.
[0038] When the sliding speed of the mounting plate 2 approaches zero and the soil softener is introduced for a period of time and still cannot drive the mounting plate 2 to slide down, it indicates that there may be objects such as stones in the soil that cannot be softened or passed through, and the staff needs to check and deal with it.
[0039] In another embodiment of the present invention, a controller is further included. The signal receiving end of the controller is used to receive the detection signal of the first detection element. The signal output end of the controller is used to control the amount of soil softener entering the first channel 15 from the first box 11 or the amount of conductive gel entering the second channel 16 from the second box 8. Specifically, the controller uses a single chip microcomputer or a controller controlled by a PLC program in the prior art. The signal output end of the controller controls the amount of soil softener entering the first channel 15 from the first box 11 by controlling the sliding speed of the output shaft of the third cylinder. The sliding speed of the output shaft of the third cylinder is the sliding speed of the first piston 12, and the amount of soil softener discharged per unit time can be controlled. The greater the soil hardness, the greater the amount of soil softener discharged per unit time. The signal output end of the controller controls the amount of conductive gel entering the second channel 16 from the second box 8 by controlling the movement stroke of the fourth cylinder. The movement stroke of the fourth cylinder is the distance required for the second piston 9 to slide, and the total amount of conductive gel discharged can be controlled. The softer the soil, the greater the total amount of conductive gel required.
[0040] In the actual design process, the signal output end of the controller is also used to control the power output of the driving member (i.e., the first cylinder). Specifically, when the first detection member detects that the sliding speed of the mounting plate 2 is gradually approaching zero, and after the soil softener is controlled to be introduced, the mounting plate 2 still cannot slide down, the controller can directly control the first cylinder to close. In addition, when an air pressure sensor is installed in the first cylinder, the signal receiving end of the controller can also receive the signal of the air pressure sensor. When the air pressure in the first cylinder continues to change (specifically, continues to increase), it can also indicate that there is a problem in pushing the mounting plate 2 to slide down. The controller can directly control the first cylinder to close. By coordinating the two detection methods, it is avoided that the needle body 13 is continuously subjected to downward force when the needle body 13 cannot slide down, causing deformation or damage to the needle body 13.
[0041] In another embodiment of the present invention, a second detection component for detecting the grounding voltage or the grounding resistance is installed in the needle body 13. The grounding effect of the needle body 13 is judged by detecting the grounding voltage or the grounding resistance in real time, and the detection data is transmitted to the monitoring terminal (the staff's mobile phone or computer) through the wireless communication module in the prior art, which is convenient for the staff to monitor in real time. During actual use, the second detection component can select the grounding resistance detector in the prior art.
[0042] In actual use, even if the soil hardness meets the requirements, after the needle body 13 is installed, if the grounding effect is not good, the conductive gel can be introduced to enhance the conductive effect between the needle body 13 and the soil to a certain extent.
