Abstract
Description
Technical Field
[0001] This utility model relates to a grounding device for electric manifold skids, belonging to the technical field of oil and gas drilling and production equipment. Background Technology
[0002] With the continuous development of oil and gas extraction, the equipment related to oil and gas field extraction is gradually becoming more electrified, and control systems such as electro-hydraulic and electro-pneumatic systems are widely used. The requirements for electrical control on site are becoming increasingly higher, and safety, standardization, and compliance are becoming more stringent. The requirements for electrical control components are somewhat limited, and the operating environment is outdoors. Therefore, it is especially necessary to meet the characteristics of safety, reliability, and ease of maintenance.
[0003] Firstly, protective grounding is not directly used for equipment operation, but is specifically designed to protect personnel safety. It is connected to the metal casing of the equipment. When a leakage accident occurs, the grounding line becomes a "safety channel" to guide the dangerous current to the ground. At the same time, the linkage protection device cuts off the power, forming a double protection. This is especially important in the power system of industrial equipment and can effectively reduce the risk of electric shock.
[0004] The grounding devices of electric manifold skids currently suffer from various problems, including inconsistent styles, non-standard grounding lines, haphazard wiring, and insecure bolt connections. In some cases, grounding is not performed at all due to a lack of available space. Furthermore, some grounding resistances are unstable and susceptible to environmental factors such as humidity and corrosion, and grounding connections are prone to loosening, leading to grounding failure.
[0005] Installing a dozen or even dozens of electrical components on a motorized manifold skid can lead to a lengthy installation time for grounding wires, and may not meet the required standards for protective grounding.
[0006] Another problem is that if several sets of electric manifold skid-mounted equipment or skid-mounted rooms of remote control systems need to be connected in parallel with protective grounding and share a grounding pin, the previous practice was rather casual, simply finding a bolt position on the skid to connect.
[0007] For the grounding system of complete sets of electrical control equipment, each electrical component needs to be connected to the grounding copper busbar and then to the grounding pin inserted into the ground at the far end. It is necessary to ensure the lowest possible resistance so that the current can be introduced into the ground with the maximum conductivity in the event of electric shock or leakage accident, so as to ensure the safety of personnel on site as much as possible. Utility Model Content
[0008] The purpose of this utility model is to provide a grounding device for electric manifold skids. This grounding device standardizes the installation of the grounding wire in the field of electric manifold skids, is easy to operate and efficient, has a neat and beautiful installation, and provides good grounding safety.
[0009] To solve the above-mentioned technical problems, the present invention provides a grounding device for electric manifold skid mounting, which includes a grounding busbar with conductivity and a grounding pin. A quick-press connection device is provided on the grounding busbar, and a grounding bus is connected to the grounding busbar. One end of the grounding bus is fixedly connected to the grounding pin, and the other end of the grounding bus is fixedly connected to the quick-press connection device. The quick-press connection device includes a connecting block. Multiple wiring connection holes are horizontally arranged on the side of the connecting block, and multiple spindle holes are vertically arranged on the top surface of the connecting block. The lower end of one spindle hole communicates with one wiring connection hole. Each spindle hole is provided with a spindle that can be lifted and moved, and the spindle is provided with a through hole.
[0010] Preferably, it also includes a busbar fixing block, wherein the grounding busbar is fixed on the busbar fixing block.
[0011] Preferably, the quick-press connection device is disposed on one side of the grounding busbar.
[0012] Preferably, a spring is provided inside the mandrel hole, the spring is sleeved on the mandrel, the top of the mandrel hole is provided with a radially protruding upper step, the bottom of the mandrel hole is provided with a radially protruding lower step, the outer circumferential surface of the mandrel is provided with a radially protruding upper step and a lower step, the upper step is located below the upper step, the lower step is located below the lower step, and the spring is located below the lower step.
[0013] Preferably, the connecting block is made of conductive copper.
[0014] The beneficial effects of this utility model are:
[0015] (1) By setting ground busbars on the top of the electric manifold skid, the bottom of the electrical components, and one side, the material of the busbars is the same as that of the grounding cable conductor, which is standard conductive copper with tin-plated anti-corrosion treatment. The vertical installation allows all electrical components to connect the grounding cable to the grounding busbar nearby, which greatly standardizes the installation of the grounding wire on the electric manifold skid and avoids the problem of arbitrarily pulling the grounding line or even not grounding to the maximum extent.
[0016] (2) By setting up a quick-press connection device, the quick-press connection device is designed with a high-rigidity spring inside. The round through hole of the contact surface of the clamping wire, i.e. the wiring hole, is made of copper to ensure that the conduction resistance is the lowest value. The surface is tin-plated for corrosion protection. The top is designed with a pressing core shaft. The top of the pressing core shaft is set with a cylinder and is equipped with a special pressing wrench. The installer can easily insert and fix the grounding wire with one hand. After releasing, the guide post is pushed back by the strong force of the spring and stays there. The grounding wire can be clamped when the hand is released. In outdoor high-altitude cold and windy sand areas, it greatly improves the efficiency of on-site installation work and saves a lot of time compared to tightening bolts one by one in the past.
[0017] (3) The grounding line is easy, beautiful and neat to install. The high rigidity spring presses the grounding wire, and the grounding wire will not loosen during the shaking during the production of the electric manifold skid and the bumps during the transportation of the equipment. The safety of the protective grounding is greatly guaranteed in the later use of the equipment. The protective grounding device will not fail because a bolt in a certain part of the grounding device system is loose. When the internal insulation of the equipment is damaged and the outer shell becomes live, the grounding wire can provide a low impedance path so that the fault current can be quickly conducted to the ground, avoiding the current from forming a circuit through the human body and causing great personal injury.
[0018] (4) It has a simple structure, is easy to install and maintain, and has high practicality. Attached Figure Description

[0026] This utility model provides a grounding device for an electric manifold skid. Please refer to [link / reference]. Figures 1 to 4 The device includes a conductive grounding busbar 1 and a grounding pin 3. The grounding busbar 1 is equipped with a quick-press connection device 2. The grounding busbar 1 is made of standard conductive copper. A grounding bus 101 is connected to the grounding busbar 1. One end of the grounding bus 101 is fixedly connected to the grounding pin 3, and the other end of the grounding bus 101 is fixedly connected to the quick-press connection device 2. The quick-press connection device 2 includes a connecting block 201. Multiple wiring connection holes 202 are horizontally arranged on the side of the connecting block 201. Multiple spindle holes 203 are vertically arranged on the top surface of the connecting block 201. The lower end of one spindle hole 203 communicates with one wiring connection hole 202. Each spindle hole 203 is provided with a spindle 204 that can be raised and lowered. A through hole 205 is provided on the spindle 204. When the spindle 204 is pressed down, the position of the through hole 205 corresponds to the position of the wiring connection hole 202.
[0027] Preferably, it also includes a busbar fixing block 102, on which the grounding busbar 1 is fixed.
[0028] Preferably, the quick-press connection device 2 is disposed on one side of the grounding busbar 1.
[0029] Preferably, a spring 206 is provided inside the mandrel hole 203, and the spring 206 is sleeved on the mandrel 204. The top of the mandrel hole 203 is provided with a radially protruding upper step portion 207, and the bottom of the mandrel hole 203 is provided with a radially protruding lower step portion 208. The outer peripheral surface of the mandrel 204 is provided with a radially protruding upper step portion 209 and a lower step portion 210. The upper step portion 209 is located below the upper step portion 207, and the lower step portion 210 is located below the lower step portion 208. The spring 206 is located below the lower step portion 210.
[0030] Preferably, the connecting block 201 is made of conductive copper.
[0031] In use, the grounding device for electric manifold skid-mounted components of this utility model connects a grounding wire to the metal casing of the electric manifold skid-mounted electrical component. One end of the grounding wire is connected to the metal casing of the electrical component, and the other end is inserted into the wiring connection hole 202 of the quick-press connection device 2. During insertion, the pressing tool wrench 211 is used to press the top of the spindle 204, causing the spindle 204 to move downward. At the same time, the lower step portion 210 of the spindle presses down the spring 206, aligning the position of the through hole 205 on the spindle 204 with the position of the wiring connection hole 202. At this time, the grounding wire can be easily inserted. Then, the pressing tool wrench 211 is released, and the spring 206 rebounds, lifting the lower step portion 210 of the spindle 204, causing the spindle 204 to move downward. Move upwards until the lower step 210 of the mandrel abuts against the lower step 208, and the upper step 209 of the mandrel abuts against the upper step 207, and hold in place. At this time, the grounding wire is locked in the wiring connection hole 202 and the through hole 205, preventing it from loosening. This achieves a quick and stable connection between the grounding wire and the quick-press connection device 2, and also connects it to the grounding busbar 1 and the grounding pin 3. The grounding pin 3 is inserted into the ground soil. The leakage current on the metal casing of the electric manifold skid-mounted electrical components is connected to the quick-press connection device 2 and the grounding busbar 1 through the grounding wire, and then from the grounding busbar 1 through the grounding bus 101 to the grounding pin 3, guiding the dangerous current to the ground and maintaining the safe operation of the electric manifold skid-mounted equipment. The entire circuit connection is simple and neat, with high connection efficiency and stable wiring, effectively avoiding the problems of arbitrarily pulling the grounding wire or even not grounding at all.
