DETAILED DESCRIPTION

[0018] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 and Figure 2 The present invention provides a stainless steel composite grounding body auxiliary extraction device, comprising a grounding body main part 1 and an extraction device assembly, the extraction device assembly is composed of a bottom shell plate 2, a cylindrical piston plate 3, a push plate 4 and an ejection mechanism, the cylindrical piston plate 3 is slidably sleeved inside the bottom shell plate 2, the ejection mechanism is arranged inside the bottom shell plate 2, the ejection mechanism is used to control the cylindrical piston plate 3 to push upward, the push plate 4 is fixedly connected at the top of the cylindrical piston plate 3, an axial cavity hole is arranged at the center of the bottom shell plate 2 and the push plate 4, the grounding body main part 1 passes through the central cavity hole and sinks into the soil, the axial cavity hole is used to position the axis of the grounding body main part 1, and the grounding body main part 1 is fixedly installed in the axial cavity hole of the push plate 4; the grounding body main part 1 is composed of an end column 11 and a column body 12, the end column 11 is cylindrical and is arranged in the axial cavity holes of the bottom shell plate 2 and the push plate 4 and fits the inner wall of the axial cavity hole, and the column body 12 is conical and used to sink into the soil.

[0020] When the grounding body main component 1 needs to be pulled out, replaced or repaired, the ejection mechanism can drive the cylindrical piston plate 3 inside the bottom shell plate 2 to be ejected upward, and the cylindrical piston plate 3 can drive the push plate 4 to move upward. Since the grounding body main component 1 is connected to the push plate 4, when the push plate 4 moves upward, the grounding body main component 1 can be pulled out upward, and due to the conical shape characteristics of the column 12 of the grounding body main component 1, when the grounding body main component 1 moves upward for a distance, the column 12 loosens in the soil (since the column 12 is conical, when the column 12 sinks into the soil, a puncture hole is formed in the soil, and the shape of the puncture hole is adapted to the shape of the column 12, and after the column 12 moves upward, a gap can be formed between the column 12 and the puncture hole in the soil according to its shape characteristics, thereby achieving a loosening effect). At this time, the grounding body main component 1 can be easily pulled out after the connection between the grounding body main component 1 and the push plate 4 is disconnected; Because the grounding body main component 1 needs to pass through the axial cavity holes of the bottom shell plate 2 and the push plate 4 when sinking into the soil, and the fit between the end column 11 and the axial cavity hole can enable the device to have a straightening effect on the grounding body main component 1, thereby preventing the grounding body main component 1 from tilting and causing structural damage when sinking into the soil.

[0021] Reference Figure 3 The bottom shell 2 is composed of an upper cylinder shell 21 and a chassis assembly 22 . The upper cylinder shell 21 is fixedly connected to the top of the chassis assembly 22 . The diameter of the chassis assembly 22 is greater than the diameter of the upper cylinder shell 21 .

[0022] When sinking the grounding body main component 1 into the soil, first dig a pre-buried groove at the predetermined sinking position, then put the extraction device assembly into the groove, and then sink the grounding body main component 1 into the soil. After the operation is completed, bury the extraction device assembly in the groove. At this time, due to the shape characteristics of the bottom shell plate 2, the chassis assembly 22 will be subjected to the pressure of the buried soil, thereby reinforcing the grounding body main component 1 in the soil and preventing the top of the grounding body main component 1 exposed to the soil from being loosened by malicious pulling.

[0023] Reference Figure 4 A cylindrical hole is provided on the side wall of the push plate 4, and the cylindrical hole is vertically staggered with the axial cavity hole of the push plate 4. A rod penetration groove a is provided on the side wall of the grounding body main component 1, and a rigid rod 41 is inserted into the cylindrical hole. The rigid rod 41 passes through the rod penetration groove a of the grounding body main component 1, and one end of the rigid rod 41 is fixedly connected to an end cover 42, and the end cover 42 is locked to the side wall of the push plate 4 through a locking member.

[0024] By passing the rigid rod 41 through the rod insertion slot a of the grounding body main component 1, the connection strength between the grounding body main component 1 and the push plate 4 can be ensured, and locking the end cover 42 and the push plate 4 can prevent the connection between the grounding body main component 1 and the push plate 4 from being destroyed, thereby preventing the grounding body main component 1 from losing its reinforcement effect in the soil.

[0025] Reference Figure 5 A piston chamber is arranged inside the bottom shell plate 2, and a cylindrical piston plate 3 is arranged inside the piston chamber. The ejection mechanism includes a piston pump 5 and a hydraulic oil tank 7. The piston pump 5 and the hydraulic oil tank 7 are both arranged inside the bottom shell plate 2. The oil inlet nozzle of the piston pump 5 is connected with the inside of the hydraulic oil tank 7, and a one-way valve is arranged in the oil inlet nozzle. The oil outlet nozzle of the piston pump 5 is connected with the piston chamber of the bottom shell plate 2 through an oil pipe 8, and a one-way valve is arranged at the connection point between the oil pipe 8 and the piston chamber. The inside of the piston chamber is connected with the inside of the hydraulic oil tank 7 through an oil pipe 9, and a one-way valve is arranged at the connection point between the oil pipe 9 and the hydraulic oil tank 7. A pipeline valve is arranged on the oil pipe 9, and its pipeline valve control end is arranged outside the bottom shell plate 2, and the piston pump 5 control end is arranged outside the bottom shell plate 2 and is connected with a control handle 6. The bottom area of ​​the cylindrical piston plate 3 is larger than the bottom area of ​​the main piston of the piston pump 5.

[0026] The piston pump 5 is driven by the control handle 6 to extract the hydraulic oil in the hydraulic oil tank 7, and discharged into the piston chamber of the bottom shell plate 2 through the oil pipe 2 9. As the hydraulic oil increases, the cylindrical piston plate 3 can be ejected. By opening the pipeline valve on the oil pipe 2 9, the hydraulic oil in the piston chamber can flow back to the hydraulic oil tank 7 through the oil pipe 2 9, and the cylindrical piston plate 3 can be reset under the effect of gravity. Since the bottom area of ​​the cylindrical piston plate 3 is larger than the bottom area of ​​the main piston of the piston pump 5, the operation of the piston pump 5 can achieve a labor-saving effect according to Pascal's law.

[0027] Reference Figure 2 ,6 The control handle 6 consists of two parts: a fixed part and an assembly part. The fixed part includes a fixed block 61, which is fixedly connected to the top of the bottom shell plate 2. The rotating parts 62 are movably sleeved at both ends of the rotating part 62, and an embedding hole is opened on one side of the rotating part 62. The assembly part includes a handle frame 63, and a cylinder frame 65 is movably sleeved on the inner wall of the handle frame 63. A screw 66 is threadedly sleeved on the inner wall of the cylinder frame 65. An insert block 64 is provided on one side of the handle frame 63, and the insert block 64 is inserted into the embedding hole. A telescopic handle 67 is provided on the other side. A threaded hole is provided on the top of the control end of the piston pump 5, and the screw 66 is threadedly sleeved in the threaded hole. A storage box 10 for storing the assembly parts is provided on the side wall of the bottom shell plate 2.

[0028] During operation, the telescopic handle 67 is moved up and down to drive the piston pump 5 to operate and pump out the oil. The lever principle of the control handle 6 can achieve a labor-saving effect. In order to avoid malicious operation, the control handle 6 is set to an assembly type. The screw 66 is twisted to separate it from the piston pump 5, and the plug 64 is pulled out from the hole of the rotating part 62 to complete the disassembly of the assembly part, and the assembly part can be locked into the storage box 10 to avoid malicious operation.

[0029] Reference Figure 7 The piston pump 5 includes an oil cylinder 51, a piston plate 52 is slidably sleeved inside the oil cylinder 51, a piston core rod 53 is fixedly connected to the top of the piston plate 52, the top of the piston core rod 53 penetrates to the top of the bottom shell plate 2 and is connected to the control handle 6, and the top of the piston plate 52 is transmission connected to the top of the inner wall of the oil cylinder 51 through a spring 54.

[0030] The control handle 6 is used to control the up and down displacement of the piston core rod 53 to drive the piston plate 52 to reciprocate inside the oil cylinder 51 to pump and discharge oil. On this basis, a spring 54 is set to exert a downward pressure on the piston plate 52 due to its elasticity, thereby achieving a more labor-saving effect when the control handle 6 controls the piston core rod 53 to move downward.

[0031] Reference Figure 7 The side wall of the piston core rod 53 is provided with an annular groove, in which a positioning ring 55 is movably sleeved, the side wall of the positioning ring 55 is fixedly connected with a threaded tube 56, and the side wall of the threaded tube 56 is fixedly connected with a handle 57. A cylindrical recess is provided on the top of the bottom shell plate 2, and the threaded tube 56 is threadedly sleeved in the cylindrical recess.

[0032] When the control handle 6 is removed, the piston core rod 53 can still move. By setting the threaded barrel 56, the piston core rod 53 can be positioned due to the threaded fit of the cylindrical recess. In addition, since the bottom shell plate 2 needs to be buried in the soil, the threaded barrel 56 and the handle 57 can also seal the piston pump 5 to prevent dust or tiny particles from entering.

[0033] Reference Figure 8The chassis assembly 22 includes a main body plate 221, and an accessory chamber is provided at the bottom of the main body plate 221, and an accessory compartment 222 is fixedly connected therein. An elastic switch 223, a reset frame 224, a battery 226, and an alarm 227 are arranged inside the accessory compartment 222. The elastic switch 223, the battery 226, and the alarm 227 are connected in series. An elastic moving plate 225 is provided at the bottom of the accessory compartment 222, and a partition 228 is fixedly connected to the top of the elastic moving plate 225. The partition 228 penetrates into the interior of the accessory compartment 222 and docks with the elastic switch 223. The partition 228 is used to cut off the power supply to the elastic switch 223, and the reset frame 224 is used to control the power on and off of the elastic switch 223. A special-shaped rod groove that penetrates to the outside is arranged inside the main body plate 221, and the control end of the reset frame 224 is arranged inside the special-shaped rod groove. The chassis assembly 22 also includes a special-shaped handle rod 229, which is used to insert into the special-shaped rod groove to trigger the reset frame 224.

[0034] Although the grounding body main component 1 can be reinforced by the bottom shell plate 2, it cannot prevent theft. When the soil burying the bottom shell plate 2 is dug up, the reinforcement effect on the grounding body main component 1 is lost, so there is a risk of theft. By improving the structure of the chassis component 22, when the soil burying the bottom shell plate 2 is dug up, the bottom shell plate 2 loses the soil pressure effect. At this time, the elastic force of the elastic shift plate 225 drives the partition 228 to move down and disconnect the elastic switch 223. At this time, the elastic switch 223 is automatically energized to form a closed circuit, and the siren 227 is used to sound an alarm to achieve an anti-theft effect. When the alarm effect is triggered during normal maintenance, the special-shaped handle rod 229 is inserted into the special-shaped rod groove to trigger the reset frame 224, and the elastic switch 223 is disconnected and energized through the reset frame 224, thereby releasing the alarm.

[0035] Reference Fig. 9 The elastic moving plate 225 includes a main moving plate 2251, and a plurality of columns 2252 are arranged on the top of the main moving plate 2251. The top of the columns 2252 penetrates into the interior of the accessory compartment 222 and is connected with an anti-slip plate 2253. The top of the anti-slip plate 2253 is transmission-connected to the top of the accessory chamber of the main plate 221 through a spring 2254.

[0036] When the chassis assembly 22 loses pressure, the elastic force of the spring 2254 can cause the elastic shift plate 225 to automatically move downward, and the elastic shift plate 225 can be prevented from being separated from the accessory compartment 222 by the cooperation of the column 2252 and the anti-slip plate 2253.

[0037] Reference Figure 3The elastic switch 223 includes two fixed shells 2231, and the two fixed shells 2231 are both slidably sleeved with power terminals 2232. The inner ends of the two power terminals 2232 penetrate the outside of the two fixed shells 2231. The side walls of the power terminals 2232 are transmission-connected to the inner walls of the fixed shells 2231 through springs 2233. One side of the two springs 2233 is provided with a strip-shaped through-groove, and the reset frame 224 passes through the two strip-shaped through-grooves and is connected to the two power terminals 2232; the reset frame 224 includes two joints 1 2241 and a joint 2 2242. The two joints 1 2241 are respectively fixedly connected to the side walls of the two power terminals 2232, and the two joints 1 2241 are respectively movably connected to the joint 2 2242 through two support rods 2243. A special-shaped sliding rod 2244 is fixedly connected to one side of the joint 2 2242, and the special-shaped sliding rod 2244 enters the special-shaped rod groove of the main plate 221.

[0038] When the partition 228 is between the two power terminals 2232, the two power terminals 2232 are disconnected and cannot be energized. When the partition 228 moves downward, the two power terminals 2232 can be displaced and contacted under the influence of the elastic force of the two spring threes 2233 to achieve an automatic energization effect. The reset frame 224 controls the disconnection of the two power terminals 2232 by pushing the special-shaped sliding rod 2244 to displace the connector two 2242. Through the connection relationship between the two support rods 2243, the two spring threes 2233 can be pushed separately to move away and disconnect, thereby achieving the control effect of the reset frame 224.
