Description

Technical Field

[0001] The utility model relates to the field of gas stations, in particular to an electrostatic detection device for gas stations. Background Art

[0002] During the work process of gas station staff, static electricity is easily generated by the friction of clothes. The oil products and steam during refueling exist in the air, and the mixture of static electricity and oil products and steam is likely to cause an explosion and fire. Therefore, it is necessary to detect whether there is static electricity when the staff is refueling. This solution specifically relates to an electrostatic detection device for gas stations;

[0003] When the existing electrostatic detection device for gas stations is in use, when the detection probe rod contacts the human body for detection, it is easy to collide and cause damage, and it is not convenient to adapt to contraction. After the detection is completed, the detection probe rod is easy to contact with external objects and cause damage, and it is not convenient for protection. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an electrostatic detection device for gas stations, which can effectively solve the technical problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An electrostatic detection device for gas stations includes a detector body. A contraction mechanism is installed at the top of the detector body. The contraction mechanism includes two detection probe rods. The two detection probe rods are movably installed at the top of the detector body. Ball bearings are movably installed at the tops of the two detection probe rods. A rod groove is opened through the inside of the detection probe rod. A chassis is fixedly installed at the bottom of the detection probe rod. A limit groove is opened at the bottom of the detection probe rod and the chassis. A guide rod is installed inside the detector body and passes through the limit groove and into the inside of the rod groove. A spring is sleeved on the periphery of the guide rod.

[0007] As a further solution of the utility model, the detection probe rod penetrates through the top of the detector body and is arranged to slide up and down. The diameter of the chassis is larger than the cross-sectional diameter of the detection probe rod.

[0008] As a further solution of the utility model, the guide rod is fixedly installed inside the detector body, and the top end of the guide rod penetrates into the rod groove and is arranged to slide.

[0009] As a further solution of the utility model, the cross-sectional diameter of the limit groove is larger than the cross-sectional diameter of the rod groove. The spring is sleeved on the periphery of the guide rod and is arranged to be mutually matched inside the limit groove.

[0010] As a further solution of the present utility model, a protection mechanism is installed at the rear of the detector body. The protection mechanism includes a protection cover which is movably installed on the top of the detector body. Card slots are opened on both sides of the protection cover. A hinge shaft is installed between the protection cover and the detector body. Card plates are fixedly installed on both sides of the top of the detector body. A buckle groove is opened at the top of the front part of the detector body. A storage groove is opened at the top of the rear part of the detector body.

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1-4 shown, an electrostatic detection device for a gas station includes a detector body 1. A shrinkage mechanism 2 is installed at the top of the detector body 1. The shrinkage mechanism 2 includes two detection probes 4. The two detection probes 4 are movably installed at the top of the detector body 1. Balls 5 are movably installed at the tops of the two detection probes 4. A rod groove 6 is opened through the inside of the detection probe 4. A chassis 8 is fixedly installed at the bottom of the detection probe 4. A limit groove 7 is opened at the bottom of the detection probe 4 and the chassis 8. A guide rod 9 is installed inside the detector body 1 and passes through the limit groove 7 and the inside of the rod groove 6. A spring 10 is sleeved on the periphery of the guide rod 9. The static voltage of the staff is detected by touching the detection probe 4.

[0023] In this embodiment, the detection probe 4 penetrates through the top of the detector body 1 and is arranged to slide up and down. The diameter of the chassis 8 is larger than the cross-sectional diameter of the detection probe 4. The chassis 8 slides inside the detector body 1 to prevent the detection probe 4 from detaching through the chassis 8.

[0024] In this embodiment, the guide rod 9 is fixedly installed inside the detector body 1. The top end of the guide rod 9 penetrates into the rod groove 6 and is arranged to slide. The detection probe 4 is connected to the inside of the detector body 1 through the guide rod 9 to enable the detection probe 4 to adapt to telescoping.

[0025] In this embodiment, the cross-sectional diameter of the limit groove 7 is larger than the cross-sectional diameter of the rod groove 6. The spring 10 is sleeved on the periphery of the guide rod 9 and is arranged to be mutually matched inside the limit groove 7. The detection probe 4 slides up and down under the action of the spring 10 to reduce external collisions.

[0026] In this embodiment, a protection mechanism 3 is installed at the rear of the detector body 1. The protection mechanism 3 includes a protection cover 11 which is movably installed on the top of the detector body 1. Card slots 12 are formed on both sides of the protection cover 11. A hinge shaft 13 is installed between the protection cover 11 and the detector body 1. Clamping plates 14 are fixedly installed on both sides of the top of the detector body 1. A buckling groove 15 is formed at the top of the front part of the detector body 1. A storage groove 16 is formed at the top of the rear part of the detector body 1. Magnetic attraction blocks 17 are installed in the storage groove 16 and at the rear of the protection cover 11. In cooperation with the telescopic movement of the detection probe 4, the detection probe 4 is covered by the protection cover 11 to improve the protection of the detection probe 4.

[0027] In this embodiment, the protection cover 11 is rotatably arranged on the top of the detector body 1 through the hinge shaft 13. An arc-shaped groove is formed inside the protection cover 11. The protection cover 11 rotates through the hinge shaft 13, so that the detection probe 4 automatically contracts through the arc-shaped groove inside the protection cover 11.

[0028] In this embodiment, the clamping plate 14 and the card slot 12 are in a clamping connection. The protection cover 11 and the storage groove 16 are arranged in a matching manner. After the protection cover 11 is rotated and opened, the magnetic attraction block 17 at the rear of the protection cover 11 is adsorbed to the magnetic attraction block 17 in the storage groove 16 and is stored through the storage groove 16.

[0029] It should be noted that the present utility model is an electrostatic detection device for a gas station. When in use, before the gas station staff carry out the refueling work, they touch the detection probe 4 to detect the static voltage in the body. When static electricity is detected, an alarm is given through the detector body 1 to prompt the staff to eliminate the static electricity. When detecting oneself or others, the detection probe 4 contacts and presses against the human body. The detection probe 4 telescopically moves in a matching manner through the telescopic movement of the spring 10 to reduce the damage caused by the collision between the human body and the detection probe 4. When protection is carried out after the detection, the protection cover 11 is rotated to cover the detection probe 4. Through the telescopic movement of the detection probe 4, the ball 5 of the detection probe 4 slides through the arc-shaped groove inside the protection cover 11 and contracts into the protection cover 11. It is fixed through the clamping connection between the clamping plate 14 and the card slot 12. The protection cover 11 is opened through the buckling groove 15. Through the mutual adsorption of the magnetic attraction block 17 in the shaft of the protection cover 11 and the magnetic attraction block 17 in the storage groove 16, the protection cover 11 is rotated into the storage groove 16 for storage.
