Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic release devices, in particular to a magnetic electrostatic release device with a conduction prompt. Background Art

[0002] Accidents caused by static electricity are numerous both domestically and internationally, and static discharge can potentially cause fires. In the petrochemical industry, the storage and transportation of flammable liquids, such as gasoline and diesel, are prone to generating static electricity during the flow and filling process. When static electricity accumulates to a certain level and discharges, the resulting spark is powerful enough to ignite the vapors of these flammable liquids, causing fires. Of the 115 gas station accidents, 86, or 75%, were caused by static electricity. Currently, for safety reasons, routine operations at oil depots, gas stations, and tankers requiring static electricity removal must be performed before any further operations can begin.

[0003] However, the static grounding devices currently used in many gas stations cannot meet actual needs and pose certain safety risks. For example, when encountering irregular containers such as cylindrical barrels, or when ground static grounding piles such as flat irons are installed in unreasonable positions, the existing clamp-type devices cannot be used safely and effectively.

[0004] Secondly, when existing electrostatic release devices are grounding charged bodies, there is no intuitive reference for testing and verification to determine whether they are correctly installed, whether the circuits are connected, and whether the static electricity is effectively released. This can easily lead to static electricity not being released due to device damage or improper installation. Therefore, it is necessary to design and manufacture a magnetic electrostatic release device with a conductive prompt to solve the real safety problems faced by many gas stations and other enterprises.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0020] Example:

[0021] like Figure 1 As shown, this embodiment provides a magnetic electrostatic release device with a conduction prompt, including a conductive clip 1, an audible and visual alarm 3 and two magnetic conductive heads 5. The audible and visual alarm 3 is provided with two wiring heads 301. The audible and visual alarm 3 is electrically connected to one end of the double-strand conductor 1 2 and the double-strand conductor 2 4 through the two wiring heads 301 respectively. The other end of the double-strand conductor 1 2 is fixedly connected to the conductive clip 1 and is conductive. The double-strand conductor 2 4 is provided with two single-wire cores 401. The two single-wire cores 401 are fixedly connected to the bottom of the two magnetic conductive heads 5 and are conductive.

[0022] Specifically, this device uses the principle of magnetic attraction, combined with the strong pressure of the copper spring needle 504 at the end of the magnetic conductive head 5, so that it can break through the paint, iron and other barriers on the surface of the detected object, and conduct static electricity through the effective connection between the copper conductive cylinder 501, the gold magnet, and the copper spring needle 504;

[0023] This device can be directly magnetically attached to the metal flat iron of the column, can automatically detect the grounding status, reduce the work pressure of the staff, and improve the efficiency of the oil filling operation. By using two magnetic conductive heads 5 instead of the conductive clamp 1, it can solve the problem of irregular containers such as cylindrical barrels, or the unreasonable installation position of the ground static grounding pile (flat iron), which makes it impossible to use the conductive clamp 1. It is more practical and enables the device to be flexibly adjusted to different equipment and usage environments. The other end of the device is a conventional conductive clamp 1, which can be used to clamp equipment or oil pipeline vehicles equipped with a special static discharge mechanism; when encountering special circumstances, the two ends of the device can be used interchangeably;

[0024] Furthermore, by connecting the sound and light alarm 3 in series in the device, the sound and light alarm 3 is powered by a dry cell battery. In the initial state during operation, the alarm sounds long. When the two magnetic conductive heads 5 at one end of the device and the conductive clip 1 at the other end are respectively connected to a charged device, equipment and a grounding structure, if the device is conductive, the sound and light alarm 3 stops sounding the alarm to prompt that the device has successfully released static electricity. The operation process is very intuitive, and can effectively reduce the effect of poor or unreleased static electricity due to installation errors or inexperienced operators, thereby further improving the safety performance of the device.

[0025] Through the above structural setting, the device has the characteristics of low development cost, high safety performance, high working efficiency, wide application range, and strong operability.

[0026] In a preferred embodiment of the present invention, the conductive clip 1 is made of metal, and a contact terminal 101 is fixedly installed on the top of the clamping arm on either side thereof, and the core of the double-strand conductor 1 2 is fixedly connected to the contact terminal 101 .

[0027] In a preferred embodiment of the present invention, further, a suspension wire rope 102 is fixedly connected between the bottoms of the two clamping arms of the conductive clamp 1 .

[0028] In a preferred embodiment of the present invention, further, the magnetic conductive head 5 includes a conductive cylinder 501, a strong magnet 503 is fixedly installed at the top center of the conductive cylinder 501, the conductive cylinder 501 is a hollow structure, and a copper spring needle 504 is provided at the top center thereof, and the copper spring needle 504 passes through the top center of the strong magnet 503.

[0029] In a preferred embodiment of the present invention, further, a press-fit bolt 502 is threadedly connected to one side of the bottom of the conductive cylinder 501 , and the single wire core 401 is tightly fixed to the inner wall of the conductive cylinder 501 through the press-fit bolt 502 .

[0030] In a preferred embodiment of the present invention, further, the top of the conductive cylinder 501 is disc-shaped, and anti-slip grooves are provided around the disc.

[0031] In a preferred embodiment of the present invention, further, a buzzer, a circuit board and a battery box are provided inside the sound and light alarm 3, and dry batteries are installed in the battery box.

[0032] In a preferred embodiment of the present invention, further, the buzzer, the circuit board and the battery box are electrically connected in series via a guide.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
