Description

Technical Field

[0001] The invention relates to the technical field of grounding protection, and in particular to a grounding device for construction of an electric power system. Background Art

[0002] As a basic protection device for power equipment and construction and operation personnel, the grounding device provides a low-impedance path for the fault current to flow back to the power supply when a ground fault occurs in the electrical equipment, limiting the overvoltage at the discharge point of the power equipment. The grounding grid is an important basic equipment for the safe and stable operation of electrical equipment. Due to the special operation form of the power system construction site, it is impossible to have the conditions of the grounding grid like conventional substations and power plants, which makes the power system construction site encounter great difficulties in lightning protection grounding, anti-static grounding, neutral point working grounding and other requirements. Since a large number of electrical preparations are arranged at the power system construction site, and most of them are put into use in open areas, there are generally no tall buildings around to provide lightning protection, and the probability of being struck by lightning is much greater than that of conventional fixed infrastructure. In addition, static electricity has direct or indirect harm to electronic equipment such as instruments and meters, automation devices and workers at the power system construction site. Therefore, reliable lightning protection and working grounding have become important safety measures that must be considered at the power system construction site.

[0003] The Chinese patent with publication number CN113607983A discloses a 10 kV overhead line maintenance intelligent temporary grounding device. The device adopts a first telescopic rod that can be freely contracted and can adjust the distance between the two concave blocks to adapt to the distance between high-voltage lines with different spacings. The pull-down handle is pulled downward, and the elastic force generated by the second return spring allows the clamping plate and the concave block to clamp the high-voltage wires, which can quickly fix the cables and make them safer to use. The current in the cable can be guided to the grounding column through the connecting wires and conductors, which facilitates rapid grounding and maintenance. The wires can be stored in a wire box, and the wire box can store and fix the first telescopic sleeve, further saving space.

[0004] However, in actual use, the temporary grounding point should be away from the crowd to avoid electric shock. The current conventional construction method is to arrange a fence around the grounding point to limit the approach of the surrounding people. However, this method has many inconveniences when used. First of all, the carrying fence occupies a large space, which makes it inconvenient to carry, and it is time-consuming and laborious to arrange the fence. In addition, the electric potential at the location of the fence is not detected, and the increase of the electric potential outside the fence is still easy to cause electric shock to people.

[0044] (4) The present invention uses a hydraulic cylinder to push the pressure plate up and down. At the same time, the driving motor drives the driving gear to rotate, and the engagement between the driving gear and the driven gear causes the grounding electrode to rotate, so that the grounding electrode is inserted into the ground in a rotational manner, thereby reducing the difficulty of grounding the grounding electrode and controlling the depth of the grounding electrode inserted into the ground. In addition, by setting the spiral groove, the contact stability between the grounding electrode and the ground is increased, thereby improving the grounding safety.

[0046] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0064] Example 1

[0065] like Figure 1 - Fig.13 As shown, an embodiment of the present invention provides a grounding device for construction of a power system, including a base plate 1, and also including a railing 7. Preferably, the railing 7 is a component of an insulating material, such as impact-resistant polystyrene, polymethacrylate, high-density polyethylene, etc. The railings 7 are arranged at equal intervals on the upper surface of the base plate 1. Preferably, there are four railings 7, and the four railings 7 are respectively placed at the four corners of the base plate 1, and a ground column 16 is movably installed at the lower end of the railing 7. The ground column 16 is made of metal, preferably copper, stainless steel, etc., and has excellent conductive and anti-corrosion properties. In addition, a warning tape 10 is installed between two adjacent railings 7, and a first winding component for winding and unwinding the warning tape 10 is provided in the railing 7.

[0066] Specifically, this embodiment surrounds the grounding component through the cooperation of multiple railings 7 and warning tapes 10 to prevent the surrounding people from approaching and improve the safety performance during grounding. The first winding component is used to realize the winding and unwinding of the warning tape 10 between two adjacent railings 7, which is beneficial for adjusting the size of the area enclosed by the warning tape 10, and is convenient for the storage and carrying of the railings 7 and the warning tape 10, thereby improving the portability of the equipment.

[0067] In addition, the power system construction grounding device provided in this embodiment also includes a detection component, which is arranged in the railing 7 and is used to detect the voltage at the ground position where the ground column 16 is located, so as to determine whether the potential there is harmful to the human body.

[0068] Specifically, the power system construction grounding device provided in this embodiment also includes a grounding component, which is arranged on the upper surface of the base plate 1 and is located at the center of the range enclosed by the warning belt 10.

[0069] like Figure 8 - Fig.13 As shown, the detection component includes an equipment cavity 36, which is arranged inside the railing 7, and a power supply 40 is installed in the equipment cavity 36. Preferably, the power supply 40 is a rechargeable battery, such as a rechargeable lithium battery. A controller 41 is also fixed in the equipment cavity 36, and the signal output end of the controller 41 is electrically connected to the alarm 30. The power supply 40 is used to power the controller 41 and the alarm 30. The alarm 30 is installed on the outside of the railing 7, and is preferably an audible and visual alarm or a buzzer.

[0070] Furthermore, the detection component also includes a detection wire 42, the lower end of the detection wire 42 is electrically connected to the ground column 16; a voltage sensor 46, the voltage sensor 46 is fixed on the railing 7, and the signal input end of the voltage sensor 46 is electrically connected to the other end of the detection wire 42, and the signal output end of the voltage sensor 46 is electrically connected to the controller 41.

[0071] It should be noted that the voltage sensor 46 can also be replaced by a potentiometer for detecting electric potential. The voltage intensity around the ground pole 16 is detected through the voltage sensor 46 and the detection wire 42, and the signal is transmitted to the controller 41. When the voltage intensity exceeds the threshold, the controller 41 transmits the signal to the alarm 30, thereby controlling the alarm 30 to indicate that there is still a risk of electric shock outside the warning belt 10, thereby reminding the staff to expand the area enclosed by the warning belt 10.

[0072] like Figure 8 - Fig.12 As shown, the first winding assembly provided in this embodiment includes a winding chamber 37 , which is opened inside the railing 7 near the upper end, and an outlet is provided on one side of the winding chamber 37 for conveying the warning tape 10 .

[0073] Specifically, the first winding component further includes a first winding roller 38, which is rotatably installed inside the winding cavity 37, and the first winding roller 38 is fixedly connected to one end of the warning tape 10. At the connection between both ends of the first winding roller 38 and the winding cavity 37, a first clockwork spring 39 is installed. The first clockwork spring 39 is used to drive the first winding roller 38 to rotate, so as to wind the pulling warning tape 10 around the first winding roller 38.

[0074] In this embodiment, by adjusting the distance between two adjacent railings 7, the warning tape 10 on the first winding roller 38 is unwound, further increasing the elastic potential energy of the first clockwork spring 39. When two adjacent railings 7 are fixed, the warning tape 10 loses the artificial pulling force. At this time, the elastic potential energy inside the first clockwork spring 39 is released, thereby pulling the warning tape 10 to wind in the reverse direction, so that the warning tape 10 contracts, making the warning tape 10 between two adjacent railings 7 in a taut state. This is beneficial for adjusting the size of the area enclosed by the warning tape 10, and is also convenient for the storage and carrying of the railings 7 and the warning tape 10, improving the portability of the device.

[0075] As Figure 4 、 Figure 5 and Figure 8 shown, the other end of the warning tape 10 provided in this embodiment is fixedly connected to the outside of one of the adjacent railings 7, and a reflective strip is provided on the surface of the warning tape 10, which is beneficial for night operations and improves the warning effect. In addition, a limiting post 17 is fixed on the warning tape 10. The limiting post 17 is used to limit the minimum distance between two adjacent railings 7, so as to prevent the length of the warning tape 10 from being less than the distance between two adjacent railings 7 during storage, providing convenience for the storage of the railings 7.

[0076] As Figure 1 、 Figure 2 、 Figure 3 and Figure 8 shown, for the convenience of storing and fixing the railings 7, support frames 2 are symmetrically fixed on the upper surface of the bottom plate 1. Preferably, the support frames 2 are in an inverted "U" shape structure, and an insulating coating is provided on the surface of the support frames 2. Partition plates 5 are symmetrically fixed on one side of each support frame 2. A clamping groove 6 is opened at the upper end of the partition plate 5. The clamping groove 6 is in a trumpet-shaped structure, and the maximum inner diameter of the clamping groove 6 is twice its minimum inner diameter. A hook 8 is fixed at a position near the upper end on the outside of the railing 7. The hook 8 is in an inverted "U" shape structure, and the hook 8 is clamped with the clamping groove 6.

[0077] In this embodiment, through the clamping connection between the hook 8 and the clamping groove 6, the railing 7 can be fixed on one side of the partition plate 5. Through the setting of the trumpet-shaped clamping groove 6, it is convenient for the hook 8 to be quickly inserted into the inside of the clamping groove 6, improving the stability of the connection between the hook 8 and the clamping groove 6.

[0078] As Figure 8 -​​​ Fig.13 As shown, in order to prevent the detection wire 42 from affecting the movement of the ground-inserted pole 16, an activity cavity 35 is opened near the lower end of the handrail 7, and a second winding component for winding the detection wire 42 is installed at the upper end of the activity cavity 35.

[0079] The second winding assembly provided in this embodiment includes a second winding roller 43 rotatably installed inside the active cavity 35. The second winding roller 43 is made of conductive material, and the second winding roller 43 is fixedly connected to one end of the detection wire 42.

The second winding roller 43 is driven to rotate by the second clockwork spring 44, and an electrical sleeve 45 is rotatably installed at the other end of the active cavity 35, and the electrical sleeve 45 is fixed on the inner wall of the active cavity 35.

[0080] In order to connect the other end of the detection wire 42 with the voltage sensor 46, the active cavity 35 provided in this embodiment is electrically connected to the electrical sleeve 45, the electrical sleeve 45 is electrically connected to the upper end of the detection wire 42, and the electrical sleeve 45 is electrically connected to the signal input end of the voltage sensor 46 through a wire, which is conducive to inputting the voltage signal near the ground column 16 into the voltage sensor 46.

[0081] like Figure 8 - Fig.12 As shown, in order to facilitate the lifting and lowering of the ground column 16 and to facilitate the storage and insertion of the ground column 16 into the ground, a longitudinal through groove 31 is opened on the outer side of the railing 7 at the position of the movable cavity 35, and a limiting groove 32 is provided on the outer side of the railing 7 at the upper end of the longitudinal through groove 31; the upper end of the ground column 16 is inserted into the movable cavity 35 and fixed with a connecting seat 34, and a pressure rod 33 is installed on one side of the connecting seat 34, and the pressure rod 33 is slidably connected with the longitudinal through groove 31, and the pressure rod 33 is preferably a component of insulating material.

[0082] In this embodiment, the pressure rod 33 is pulled up and down through the sliding connection between the pressure rod 33 and the longitudinal through groove 31, so that the pressure rod 33 drives the connecting seat 34 to slide inside the movable cavity 35, and further adjusts the position of the ground column 16, which is beneficial for the ground column 16 to be inserted into the ground. With the setting of the limit groove 32, the pressure rod 33 can be fixed when the ground column 16 is stored, so as to facilitate the storage of the railing 7.

[0083] like Figure 6As shown, the grounding component includes a carrier plate 12, which is a component made of insulating material.

Through the setting of the bus 14, it can play a role in voltage equalization, so that the potential distribution of the entire electrical system is more uniform, avoiding the occurrence of ground potential counter-attack accidents.

[0084] Furthermore, the grounding component also includes a connecting sleeve 27, which is fixed on the bus 14 at equal intervals, and the connecting sleeve 27 is electrically connected to the bus 14, and a grounding electrode 15, which is installed on the connecting sleeve 27, and a spiral groove 26 is provided on the surface of the grounding electrode 15. The lower end of the grounding electrode 15 passes through the carrier plate 12 and the base plate 1 and is installed with a tip 28. The connecting sleeve 27 is in contact with the grounding electrode 15 and is electrically connected. Through the setting of the tip 28, the grounding electrode 15 is easily inserted into the ground, and tip discharge can be achieved to improve the discharge effect. Under the setting of the spiral groove 26, the contact effect between the grounding electrode 15 and the ground is improved, thereby improving the grounding effect.

[0085] Specifically, the grounding assembly provided in this embodiment also includes a fixing frame 21, and the fixing frame 21 is preferably an "H"-shaped structure, and the fixing frame 21 is fixed between the two supporting frames 2. A fixing sleeve 29 is rotatably installed at the middle position of the fixing frame 21, and a turntable 20 is provided at one end of the fixing sleeve 29, and a winding reel 18 is fixedly provided on the outer side of the fixing sleeve 29, and a connecting cable 19 is wound on the winding reel 18, one end of the connecting cable 19 is electrically connected to the bus 14, and the other end of the connecting cable 19 can be externally connected to a grounding wire clamp.

[0086] When in use, the turntable 20 is rotated to drive the winding reel 18 to rotate, thereby adjusting the length of the connecting cable 19, connecting one end of the connecting cable 19 to the grounding clamp to facilitate the connection of the connecting cable 19 to the transmission line, and electrically connecting the other end of the connecting cable 19 to the bus 14 to achieve grounding of the transmission line.

In order to avoid the increase of the potential on the pressure plate 22, an insulating column is installed at the connection between the upper end of the grounding electrode 15 and the pressure plate 22. The upper end of the grounding electrode 15 passes through the pressure plate 22 and is installed with a driven gear 25. An insulating sleeve is provided between the driven gear 25 and the grounding electrode 15, and the grounding electrode 15 is rotatably connected to the pressure plate 22.

[0088] In this embodiment, the pressure plate 22 is pushed up and down by the hydraulic cylinder 11. At the same time, the driving motor drives the driving gear 24 to rotate, and the engagement between the driving gear 24 and the driven gear 25 causes the grounding electrode 15 to rotate, so that the grounding electrode 15 is inserted into the ground in a rotating manner, so as to reduce the difficulty of grounding the grounding electrode 15 and control the insertion depth of the grounding electrode 15 into the ground.

[0089] like Figure 1 and Figure 2 As shown, in order to facilitate the movement of the equipment, a connecting plate 4 is fixed above the base plate 1 near one side, both ends of the connecting plate 4 are fixedly connected to the support frame 2, and a push rod 9 is installed on the outside of the connecting plate 4. In addition, rollers are installed at the four corners of the bottom of the base plate 1 to facilitate the pushing of the equipment.

[0090] When in use, the base plate 1 is pushed to the specified position, the hydraulic cylinder 11 is started, and the pressure plate 22 is pushed up and down by the hydraulic cylinder 11. At the same time, the driving motor drives the driving gear 24 to rotate, and the engagement between the driving gear 24 and the driven gear 25 causes the grounding electrode 15 to rotate, so that the grounding electrode 15 is inserted into the ground in a rotating manner, so as to reduce the difficulty of the grounding electrode 15 to be grounded and control the insertion depth of the grounding electrode 15 into the ground.

[0091] The railing 7 is removed from the partition 5 in sequence, the position of the railing 7 is adjusted, and the pressure rod 33 is pressed. The sliding connection between the pressure rod 33 and the longitudinal through groove 31 is used to pull the pressure rod 33 up and down, so that the pressure rod 33 drives the connecting seat 34 to slide inside the movable cavity 35, and the position of the ground column 16 is further adjusted, which is conducive to the insertion of the ground column 16 into the ground to achieve the fixation of the railing 7. By adjusting the distance between the two adjacent railings 7, the warning tape 10 on the first winding roller 38 is unwound, and the elastic potential energy of the first spring 39 is further increased. When the two adjacent railings 7 are fixed, the warning tape 10 loses the artificial pulling force. At this time, the elastic potential energy inside the first spring 39 is released, thereby pulling the warning tape 10 to rewind in the opposite direction, so that the warning tape 10 shrinks, so that the warning tape 10 between the two adjacent railings 7 is in a taut state, which is conducive to adjusting the size of the area enclosed by the warning tape 10.

[0092] Rotate the turntable 20 to drive the winding reel 18 to rotate, thereby adjusting the length of the connecting cable 19, connect one end of the connecting cable 19 to the grounding clamp to facilitate the connection of the connecting cable 19 to the transmission line, and electrically connect the other end of the connecting cable 19 to the bus 14 to achieve grounding of the transmission line.

[0093] The voltage intensity around the ground pole 16 is detected by the voltage sensor 46 and the detection wire 42, and the signal is transmitted to the controller 41. When the voltage intensity exceeds the threshold, the controller 41 transmits the signal to the alarm 30, thereby controlling the alarm 30 to indicate that there is still a risk of electric shock outside the warning belt 10, thereby reminding the staff to expand the area enclosed by the warning belt 10.

[0094] Example 2

[0095] An embodiment of the present invention provides a method for using a power system construction grounding device, which specifically includes the following steps:

[0096] Move the base plate 1 to a predetermined construction position;

[0097] The hydraulic cylinder 11 is started to push the pressing plate 22 up and down through the hydraulic cylinder 11, and the driving gear 24 is driven to rotate by the driving motor. Through the meshing of the driving gear 24 and the driven gear 25, the grounding electrode 15 is inserted into the ground in a rotating manner to control the depth of the grounding electrode 15 inserted into the ground;

[0098] The position of the railing 7 is disassembled and adjusted, and the position of the ground-inserted column 16 is adjusted by using the sliding connection between the pressure rod 33 and the longitudinal through groove 31 to achieve the fixing of the railing 7;

[0099] By adjusting the distance between two adjacent railings 7, unwinding the warning tape 10, and utilizing the elastic potential energy of the first spring 39, the warning tape 10 is reversely rewound after losing the pulling force to reach a taut state, thereby adjusting the size of the area enclosed by the warning tape 10;

[0100] Rotate the turntable 20 to drive the cable reel 18 to rotate, adjust the length of the connecting cable 19, connect one end of the connecting cable 19 to the grounding clamp, and electrically connect the other end to the busbar 14 to achieve grounding of the power transmission line;

[0101] The voltage sensor 46 and the detection wire 42 are used to detect the voltage intensity around the ground-inserted pole 16, and the alarm 30 is controlled by the controller 41 to sound an alarm;

[0102] When the voltage intensity exceeds a preset threshold, the controller 41 transmits a signal to the alarm 30, which issues a warning to the worker that there is a risk of electric shock in the grounding area;

[0103] The area enclosed by the warning belt 10 is expanded.

[0104] Furthermore, when the device needs to be moved, the warning tape 10 and the detection wire 42 are recovered by the reeling assembly, and the railing 7 is fixed to the base plate 1 by the engagement of the hook 8 and the slot 6 .

[0105] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0106] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
