Description

Technical Field

[0001] The utility model relates to the field of hollow current-limiting reactors, in particular to a hollow current-limiting reactor with an anti-theft function. Background Technique

[0002] The main reason for the need to prevent theft of hollow current-limiting reactors is that the reactors contain metal components, such as copper coils, etc. These metals have a certain economic value and may attract thieves. Reactors are an important part of the power system, responsible for limiting short-circuit current and improving system stability. Theft of reactors may have a serious impact on the safe and stable operation of the power system. Therefore, appropriate anti-theft measures need to be taken for hollow current-limiting reactors.

[0003] After retrieval, Chinese Patent Publication No.: CN220381875U discloses a hollow current-limiting reactor with an anti-theft function. Through the cooperation of a vibration sensor, an alarm, a first circular frame, a second circular frame, a first guard rod, a second guard rod, a toothed ring, a self-locking motor, a gear and a ball, it has the advantages of being able to protect and prevent theft of the hollow current-limiting reactor body. Under the self-locking action of the self-locking motor, the second circular frame and the second guard rod are limited, so that illegal personnel cannot enter the interior to remove the hollow current-limiting reactor body. When violently disassembled, the vibration sensor detects severe vibration and feeds back the information to the control box to control the alarm to alarm and deter illegal personnel.

[0004] In the above technical solution, multiple sets of round rods are used in cooperation with the motor and the vibration sensor to prevent unauthorized personnel from disassembling and stealing the hollow current-limiting reactor. However, when unauthorized personnel steal the hollow current-limiting reactor as a whole and carry the hollow current-limiting reactor onto a trolley or transportation equipment, the above anti-theft method will lack anti-theft function, thus reducing the anti-theft effect. Therefore, a hollow current-limiting reactor with an anti-theft function is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a hollow current-limiting reactor with an anti-theft function, aiming to improve the problem that the hollow current-limiting reactor with an anti-theft function in the prior art lacks anti-theft function when unauthorized personnel carry the hollow current-limiting reactor as a whole for theft.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A hollow current-limiting reactor with an anti-theft function, including a hollow current-limiting reactor body, the bottom of the hollow current-limiting reactor body is fixedly connected with a base, the bottom of the base is fixedly connected with a support column, and an anti-theft structure is arranged on the surface of the support column. The anti-theft structure includes a mounting plate, the inner wall of the mounting plate is threadedly connected with a mounting bolt, the outer wall of the support column is slidably connected with a shielding ring, the bottom of the shielding ring is fixedly connected with spikes, the inner wall of the shielding ring is threadedly connected with a threaded rod, the top of the threaded rod is fixedly connected with a dial ring, the outer wall of the threaded rod is rotatably connected with a fixing plate, and an anti-theft component is arranged at the bottom of the base.

[0013] As a further description of the above technical solution:

[0014] An embedding groove is formed on the lower surface of the base, a pressing switch is fixedly connected to the inner wall of the embedding groove, a positioning plate is fixedly connected to the outer wall of the fixing plate, a pressing rod is slidably connected to the inner wall of the positioning plate, a spring is sleeved on the outer wall of the pressing rod, a lighting tube is arranged on the outer wall of the hollow current-limiting reactor body, and an alarm is arranged on the top of the lighting tube.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, the hollow current-limiting reactor is fixed to the ground through the cooperation of the mounting plate and the mounting bolts. The U-shaped frame cooperates with the U-shaped lock to penetrate the dial ring, the fixed pipe and the support column, preventing the threaded rod from rotating and causing the shielding ring to displace. The shielding ring cooperates with the spikes to prevent unauthorized personnel from removing the mounting bolts and stealing the entire hollow current-limiting reactor.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a hollow current-limiting reactor with an anti-theft function, including a hollow current-limiting reactor body 1. A base 2 is fixedly connected to the bottom of the hollow current-limiting reactor body 1. A round rod is fixedly connected to the top of the base 2. At the same time, a motor is arranged beside the base 2. The motor drives a driving wheel, which drives a driven wheel engaged with it, so that the driven wheel drives the second group of round rods at its top to rotate, intersect with the fixed round rods, and shield and prevent theft of the hollow current-limiting reactor body 1. A support column 3 is fixedly connected to the bottom of the base 2. There are four groups of support columns 3, and the four groups of support columns 3 are distributed in a rectangular array with the center point of the base 2 as the axis of symmetry. An anti-theft structure is arranged on the surface of the support column 3. The anti-theft structure includes a mounting plate 4. The number of mounting plates 4 arranged is the same as that of the support columns 3. The inner wall of the mounting plate 4 is threadedly connected with a mounting bolt 5. Four groups of equally spaced mounting bolts 5 are arranged on the surface of each mounting plate 4 to strengthen the fixation degree of the mounting plate 4 to the ground. A shielding ring 6 is slidably connected to the outer wall of the support column 3. A spike 7 is fixedly connected to the bottom of the shielding ring 6. The inner wall of the shielding ring 6 is threadedly connected with a threaded rod 8. The top end of the threaded rod 8 is fixedly connected with a dial ring 9. By rotating the dial ring 9, the threaded rod 8 can be driven to rotate, so that the shielding ring 6 descends or ascends. The outer wall of the threaded rod 8 is rotatably connected with a fixing plate 10. An anti-theft component is arranged at the bottom of the base 2.

[0033] Referring to Figures 3 - 5 , the anti-theft component includes a through hole 11. Through holes 11 are respectively formed through the central axes of the dial ring 9, a group of support columns 3 and the fixing plate 10. A support plate 12 is fixedly connected to the bottom of the base 2. A U-shaped frame 13 is arranged inside the through hole 11. A U-shaped lock 14 is arranged on the surface of the U-shaped frame 13. The upper surface of the mounting plate 4 is fixedly connected to the lower surface of the support column 3. The through hole 11 is formed through the outer wall of the dial ring 9. The outer wall of the U-shaped frame 13 is adapted to the inner wall of the through hole 11. The U-shaped frame 13 can sequentially pass through the dial ring 9, the support column 3 and the fixing plate 10 through the opening of the through hole 11.

[0034] Referring to Figure 1 、 Figure 3 、 Figure 5The lower surface of the base 2 is provided with an embedding groove 19, and the inner wall of the embedding groove 19 is fixedly connected with a push switch 18. When the push switch 18 is released, the alarm 20 and the lighting tube 21 are activated, the alarm 20 generates a buzzer, and the lighting tube 21 turns on the lighting, and the sound and light can deter unauthorized personnel at night. The outer wall of the fixed plate 10 is fixedly connected with a positioning plate 17, and the inner wall of the positioning plate 17 is slidably connected with an extrusion rod 15, which provides a pressing force to the push switch 18, and the outer wall of the extrusion rod 15 A spring 16 is provided on the wall sleeve, a lighting tube 21 is provided on the outer wall of the hollow current limiting reactor body 1, an alarm 20 is provided on the top of the lighting tube 21, the lighting tube 21 and the alarm 20 are both installed on the disc at the top of the round rod, and are located at the top position of the hollow current limiting reactor body 1, the bottom of the extrusion rod 15 is in contact with the outer wall of the U-shaped frame 13, the top of the extrusion rod 15 is in contact with the bottom of the push switch 18, the top of the spring 16 is fixedly connected to the lower surface of the positioning plate 17, and the extrusion rod 15 is arranged in an I-shape.

[0035] Working principle: When unauthorized personnel want to steal the hollow current-limiting reactor body 1 as a whole, they will separate the mounting bolts 5 from the mounting plate 4 to steal the hollow current-limiting reactor body 1. At this time, due to the setting of the spikes 7, it is impossible to remove the mounting bolts 5. When the unauthorized personnel use tools such as wrenches to pry the mounting bolts 5, the mounting bolts 5 will be blocked by the shielding ring 6 after they are away from the mounting plate 4 for a distance, making it impossible to completely remove the mounting bolts 5. Since the U-shaped frame 13 and the U-shaped lock 14 fix the dial ring 9, the support column 3 and the fixing plate 10, the dial ring 9 cannot be rotated. If the unauthorized personnel damage the U-shaped frame 13, the U-shaped After the frame 13 is moved out of the through hole 11, the extrusion rod 15 is separated from the extrusion force of the U-shaped frame 13, and the spring 16 recovers its deformation, so that the push switch 18 is separated from the pressing force. At this time, the alarm 20 and the lighting tube 21 are turned on at the same time, which has a deterrent effect on unauthorized personnel. When the staff needs to move the hollow current-limiting inductor body 1 as a whole, the alarm 20 and the lighting tube 21 are turned off through the PLC controller, and the U-shaped lock 14 is unlocked to separate it from the U-shaped frame 13, and the dial ring 9 is manually flipped. After the dial ring 9 is rotated, it drives the threaded rod 8 to rotate, so that the shielding ring 6 drives the spike 7 to rise, which is convenient for the staff to replace the position of the hollow current-limiting inductor body 1.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
