Description

Technical Field

[0001] This invention relates to the field of construction technology for grounding electrodes made of precious metal materials in oil and gas production equipment, specifically to a grounding electrode installation and construction device. Background Technology

[0002] Drill pipes are crucial equipment for oil and gas extraction. Most of the grounding electrodes for drill pipes are made of electrical contact precious metal materials. Lightning protection is essential for these grounding electrodes made of electrical contact precious metal materials. Grounding is a vital part of lightning protection engineering. Whether it's direct lightning strike protection or protection against lightning electrostatic induction, electromagnetic induction, and lightning surge intrusion, the ultimate goal is to send the lightning current into the earth. The function of protective grounding is to create a good metallic connection between the non-energized metal parts of electrical equipment and the grounding electrode, reducing the voltage to ground at the connection point and preventing the risk of electric shock. During construction, the grounding electrode needs to be buried in the ground to ensure good contact with the ground and conduct electrical energy to the earth.

[0003] However, traditional grounding electrode installation mostly involves manually drilling holes with the aid of tools, inserting the grounding electrode into the holes, and finally filling the gaps in the inner wall of the holes with filler. The soil inside the holes is prone to collapse when the drill bit is pulled out, making it difficult for the grounding electrode to be vertical after insertion and for the filler to be evenly distributed in the holes, thus reducing conductivity. Summary of the Invention

[0004] The purpose of this invention is to provide a grounding electrode installation and construction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grounding electrode installation and construction device, including a motor, and further comprising,

A discharge hole is provided on the bottom side of the drill bit, with the opening of the discharge hole facing the opposite direction to the rotation direction of the drill bit during drilling. A feed hole is provided on one side of the top of the drill rod. A vertical through groove is provided in the middle of the drill rod. A baffle tube and a funnel tube are fixedly connected to the top of the drill rod.

[0007] The mounting tube is equipped with a snap-fit ​​assembly for quick assembly and disassembly of the drill pipe.

[0008] Preferably, a drive rod is fixedly connected to the output shaft end of the motor. A groove is provided at the bottom of the drive rod, and a positioning hole is provided on the lower side of the drive rod. The top of the filling rod is slidably connected to the inner wall of the groove of the drive rod, and the bottom of the drive rod is slidably inserted into the inner wall of the mounting tube. An insertion hole is provided on the surface of the mounting tube and corresponds to the positioning hole.

[0009] Preferably, the snap-fit ​​assembly includes a mounting plate, which is fixedly sleeved on the outer wall of the mounting tube. Both sides of the mounting plate have through holes that correspond to the insertion holes and positioning holes of the mounting tube. Insert rods are slidably inserted through the inner walls of the through holes, insertion holes, and positioning holes of the mounting plate. A side plate is fixedly connected to one side of the insert rod, and a handle is fixedly connected to the side of the side plate away from the insert rod. An annular groove is formed on the surface of the insert rod.

[0010] Preferably, an L-shaped plate two is fixedly connected to the top of the mounting plate on the side away from the side plate, a spring telescopic rod is fixedly connected to the upper part of the L-shaped plate two, and an L-shaped plate one is fixedly connected to the bottom of the spring telescopic rod. A slot is opened on the surface of the L-shaped plate one, and the inner wall of the slot slides and engages with the inner wall of the annular groove.

[0011] Preferably, a connecting plate is fixedly connected to the top of the motor, a hydraulic rod and a sliding rod are fixedly connected to the top of the connecting plate, a fixed tube is slidably sleeved on the top of the sliding rod, a top plate is fixedly connected to the top of the hydraulic rod and the fixed tube, a support plate is fixedly connected to the bottom of the top plate, and a bottom plate is fixedly connected to the bottom of the support plate.

[0012] Preferably, self-locking wheel sets are fixedly connected to the four bottom corners of the base plate.

[0013] Preferably, the surface of the base plate has an opening and a push rod motor is fixedly installed above the opening. The bottom of the push rod of the push rod motor is fixedly connected to a pressure plate, and the bottom of the pressure plate is fixedly connected to an anti-slip spike.

[0014] Preferably, the surface of the support plate is provided with a strip-shaped through groove, and the top of the base plate is fixedly connected to a power supply module and a hydraulic oil tank. The hydraulic oil tank is connected to the hydraulic rod through an oil supply pipe, and the power supply module is connected to the motor and the push rod motor through a power supply line. The oil supply pipe and the power supply line pass through the strip-shaped through groove of the support plate.

[0015] Preferably, a circuit control panel is fixedly installed on one side of the support plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention involves setting up a drill rod, drill bit, discharge hole, and filler rod. After drilling is completed, the mounting tube and drive rod are disassembled, and the filler rod is removed from the drill rod, exposing the vertical through groove in the middle of the drill rod. Next, a grounding electrode is inserted into the vertical through groove of the drill rod. At this point, the grounding electrode surface is smooth and not welded with a grounding wire, allowing it to be fully inserted into the vertical through groove of the drill rod. Then, filler material is poured into the mounting tube and funnel tube. The filler material enters the drill rod through the inlet hole. After the drill rod is filled, the mounting tube and drive rod are disassembled. The moving rod is reconnected, the motor and hydraulic rod are turned on, the motor output shaft drives in reverse, and the hydraulic rod slowly pulls the drill rod upward and rotates it in the opposite direction. As the drill rod rotates upward, the filler material inside the drill rod is thrown out through the discharge hole and spirally fills the gap in the borehole along the surface of the grounding electrode. The grounding electrode gradually slides out from the vertical through groove of the drill rod and stays in the borehole. With the spiral discharge of the filler material, it can maintain a vertical state, and when the drill rod separates from the soil, the filler material can be replenished in time, thereby avoiding soil collapse and uneven distribution of filler material.

[0018] This invention, by setting up a snap-fit ​​assembly, allows for quick assembly and disassembly of the mounting tube and drive rod, enabling the switching and installation of the filling rod and grounding electrode, thereby improving construction efficiency.

[0019] This invention incorporates a filling rod and a baffle tube. The bottom shape of the filling rod matches the bottom shape of the drill bit, forming a complete drill bit shape. During drilling, no soil will enter the vertical groove of the drill rod. The baffle tube, in conjunction with the groove at the bottom of the drive rod, limits and fixes the filling rod. When filling material is added, the baffle tube also acts as a barrier, preventing the filling material from falling into the gap between the grounding electrode and the vertical groove of the drill rod.

[0020] This invention, by setting a self-locking wheel assembly and anti-slip spikes, facilitates the movement and switching of the drilling position while providing good stability when fixed, avoiding position deviation during drilling and preventing drilling failure. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 The present invention provides a technical solution: a grounding electrode installation and construction device, including a motor 1, and further comprising,

[0031] Drill rod 2, drill bit 3 is fixedly connected to the bottom of drill rod 2. Both drill rod 2 and drill bit 3 are hollow inside. A discharge hole 4 is opened on the bottom side of the drill bit 3. The opening of the discharge hole 4 faces the opposite direction of the rotation direction of the drill bit 3 when drilling. A feed hole 5 is opened on one side of the top of drill rod 2. A vertical through groove is opened in the middle of drill rod 2. A baffle tube 6 and a funnel tube 9 are fixedly connected to the top of drill rod 2. A filling rod 7 is slidably connected through the vertical through groove of drill rod 2 and the inner wall of baffle tube 6. A limit ring 8 is fixedly sleeved on the surface of filling rod 7. The bottom of the limit ring 8 fits the top of baffle tube 6. An installation tube 10 is fixedly connected to the top of funnel tube 9. The shape and size of filling rod 7 are compatible with the grounding electrode.

[0032] The mounting tube 10 is externally fitted with a snap-fit ​​assembly for quick assembly and disassembly of the drill rod 2;

[0033] A drive rod 11 is fixedly connected to the output shaft end of motor 1. The bottom of the drive rod 11 has a groove and the lower side of the drive rod 11 has a positioning hole 12. The top of the filling rod 7 is slidably connected to the inner wall of the groove of the drive rod 11, and the bottom of the drive rod 11 is slidably inserted into the inner wall of the mounting tube 10. The surface of the mounting tube 10 has an insertion hole that corresponds to the positioning hole 12. The drive rod 11 and the mounting tube 10 are detachable, which facilitates switching the filling rod 7 and the grounding electrode.

[0034] The snap-fit ​​assembly includes a mounting plate 13, which is fixedly sleeved on the outer wall of the mounting tube 10. Both sides of the mounting plate 13 have through holes that correspond to the insertion holes and positioning holes 12 of the mounting tube 10. Insert rods 14 are slidably inserted through the through holes of the mounting plate 13, the insertion holes of the mounting tube 10, and the inner walls of the positioning holes 12. A side plate 15 is fixedly connected to one side of the insert rod 14, and a handle 16 is fixedly connected to the side of the side plate 15 away from the insert rod 14. An annular groove 17 is formed on the surface of the insert rod 14. The mounting tube 10 and the drive rod 11 are snapped together by the insert rod 14, so that the motor 1 can drive the drill rod 2 to rotate.

[0035] An L-shaped plate 20 is fixedly connected to the top of the mounting plate 13 on the side away from the side plate 15. A spring telescopic rod 21 is fixedly connected to the upper part of the L-shaped plate 20. An L-shaped plate 18 is fixedly connected to the bottom of the spring telescopic rod 21. A slot 19 is provided on the surface of the L-shaped plate 18. The inner wall of the slot 19 slides and engages with the inner wall of the annular groove 17. The insertion rod 14 is held in place by the L-shaped plate 18, the slot 19, and the annular groove 17, so as to prevent the insertion rod 14 from slipping when the drill rod 2 rotates.

[0036] A connecting plate 23 is fixedly connected to the top of the motor 1. A hydraulic rod 22 and a sliding rod 26 are fixedly connected to the top of the connecting plate 23. A fixed tube 25 is slidably sleeved on the top of the sliding rod 26. A top plate 24 is fixedly connected to the top of the hydraulic rod 22 and the fixed tube 25. A support plate 27 is fixedly connected to the bottom of the top plate 24. A bottom plate 28 is fixedly connected to the bottom of the support plate 27. The drill rod 2 is driven to move up and down by the hydraulic rod 22 to change the drilling depth. The fixed tube 25 and the sliding rod 26 improve the stability of the up and down movement of the connecting plate 23.

[0037] The bottom four corners of the base plate 28 are fixedly connected with self-locking wheel sets 29. The self-locking wheel sets 29 can lock themselves, which facilitates the movement of the entire device. At the same time, the self-locking improves stability and prevents accidental slippage.

[0038] The surface of the base plate 28 has an opening and a push rod motor 32 is fixedly installed above the opening. The bottom of the push rod of the push rod motor 32 is fixedly connected to a pressure plate 33, and the bottom of the pressure plate 33 is fixedly connected to an anti-slip spike 34. After the working position is determined and the self-locking wheel assembly 29 is self-locked, the push rod motor 32 is turned on to press down the pressure plate 33, so that the anti-slip spike 34 is pressed into the soil, further improving the stability of the entire device and preventing movement during drilling.

[0039] The surface of the support plate 27 is provided with a strip-shaped through groove. The top of the base plate 28 is fixedly connected to the power supply module 30 and the hydraulic oil tank 31. The hydraulic oil tank 31 is connected to the hydraulic rod 22 through the oil supply pipe. The power supply module 30 is connected to the motor 1 and the push rod motor 32 through the power supply line. The oil supply pipe and the power supply line pass through the strip-shaped through groove of the support plate 27 for power supply and transmission of hydraulic oil.

[0040] A circuit control panel 35 is fixedly installed on one side of the support plate 27 to control the working status of the power supply module 30, hydraulic oil tank 31, motor 1, push rod motor 32 and hydraulic rod 22.

[0041] Working principle: In the initial state, the filling rod 7 is located inside the drill rod 2. The bottom shape of the filling rod 7 matches the bottom shape of the drill bit 3, forming a complete drill bit shape. The base plate 28 is moved to the side of the grounding well, and the self-locking wheel assembly 29 is self-locked. The push rod motor 32 is activated to press down the pressure plate 33 and the anti-slip spikes 34 to improve stability. Then, the motor 1 and the hydraulic rod 22 are activated. The motor 1 drives the drill rod 2 to rotate through the drive rod 11 and the installation pipe 10. In conjunction with the hydraulic rod 22, the motor 1 is pressed down, causing the drill rod 2 and the drill bit 3 to drill into the soil to make a hole. The entire drill rod 2 is drilled into the soil until the funnel pipe 9 and the installation pipe are reached. 10 is close to the ground. The top of the filling rod 7 is blocked by the groove at the bottom of the drive rod 11 and will not move upward. The opening of the discharge hole 4 faces the opposite direction of rotation when the drill rod 2 is drilling, so no soil will enter. Then, turn off the motor 1 and the hydraulic rod 22, lift the L-shaped plate 18 to disengage the slot 19 from the annular groove 17, and then hold the handle 16 to disengage the insertion rod 14 from the mounting plate 13, thereby separating the drive rod 11 and the mounting tube 10. Next, remove the filling rod 7 from the drill rod 2, exposing the vertical through groove in the middle of the drill rod 2. Then, insert the grounding electrode into the vertical through groove of the drill rod 2. At this time, the grounding electrode is activated. The grounding electrode surface is not welded with a grounding wire and has a smooth surface, allowing it to be fully inserted into the vertical through slot of drill rod 2. Then, filler material is poured into the installation tube 10 and funnel tube 9. The filler material enters the drill rod 2 through the inlet hole 5. After the drill rod 2 is filled, the installation tube 10 and drive rod 11 are reconnected, and motor 1 and hydraulic rod 22 are turned on. The output shaft of motor 1 drives in reverse, and hydraulic rod 22 slowly pulls motor 1 upward. As drill rod 2 rotates in reverse and moves upward, the filler material inside drill rod 2 is thrown out through the discharge hole 4, spirally filling the drill hole gap along the surface of the grounding electrode. The grounding electrode then exits from drill rod 2... The drill rod gradually slides out of the vertical groove and stops inside the borehole. With the spiral discharge of the filler material, it can maintain a vertical state. When the drill rod 2 separates from the soil, the filler material can be replenished in time, thereby avoiding soil collapse and uneven distribution of filler material. This solves the problem that traditional grounding electrode installation construction mostly uses manual drilling with the help of tools, then inserts the grounding electrode into the hole, and finally puts filler material into the gaps in the hole wall. The soil in the hole wall is easy to collapse when the drill bit is pulled out, making it difficult for the grounding electrode to maintain a vertical state after insertion and making it difficult for the filler material to be evenly distributed in the hole, thus reducing the conductivity.

[0042] After all the filler material is discharged, the grounding electrode is buried underground. The grounding work is completed by welding the grounding wire to the upper side of the grounding electrode and connecting it to the non-energized metal parts of the equipment. The grounding electrode is made of a new type of electrical contact precious metal material, such as pure copper or copper alloy, which can provide extremely low grounding resistance and ensure that fault current or lightning current can be discharged into the ground quickly and smoothly. Copper has good corrosion resistance in most soil environments and has high mechanical strength, making it more reliable in use.
