Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to an online detector with an explosion-proof structure. Background Art

[0002] There are many types of equipment in petrochemical plants, and the media are flammable and explosive, which leads to high operational risks. Many of the media are extremely flammable and explosive, such as hydrogen, hydrogen sulfide, butane, acetylene, liquefied gas, etc. During operations, users often need to perform various tests on the gas at the location through online detectors.

[0003] At present, ordinary online detection equipment is usually made of laptop computers or industrial plastic instrument boxes. When using it, it is necessary to arrive at the site, then turn on the detector and detect the gas through the multiple sets of detection heads on the upper end.

[0004] However, the existing detectors are unable to seal the battery, circuit board and other locations of the detector when in use, because during normal use, it is necessary to open multiple sets of vents to facilitate air circulation of the entire device. However, when the device is located in such a harsh environment, when a part of the flammable and explosive medium enters the body through the vents, it is easy to explode, thereby affecting the use effect of the device. In view of this, we propose an online detector with an explosion-proof structure. Utility Model Content

[0005] The purpose of the utility model is to provide an online detector with an explosion-proof structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: an online detector with an explosion-proof structure, comprising a body, a bottom plate fixedly mounted on the inner wall of the body, a circuit board fixedly mounted on the upper end of the bottom plate, a cover hingedly connected to the upper side wall of the body, a support plate fixedly mounted on the inner wall of the body, a display screen body arranged on the upper surface of the support plate, a protective structure arranged inside the body, and the protective structure comprising:

[0009] Preferably, the sealing structure includes sealing airbags fixedly mounted on four sides of the sealing plate, two groups of air storage airbags are fixedly mounted on both sides of the lower end of the support plate, and the air storage airbags and the sealing airbags are connected via two groups of ventilation pipes.

[0010] Preferably, directional openings are provided on both sides of the lower end of the support plate, and a slide plate is fixedly mounted on the lower end of the sealing plate, and the slide plate is slidably connected to the inner wall of the directional opening.

[0011] Preferably, the interior of the air storage airbag is in a state of being filled with gas, and the gas content inside the sealing airbag is one-half.

[0014] Compared with the prior art, the utility model provides an online detector with an explosion-proof structure, which has the following beneficial effects:

[0015] 1. The online detector with explosion-proof structure is convenient for explosion-proof protection of the inside of the machine body by setting up a protective structure. When the machine body is located in a flammable and explosive environment for detection, the user can energize the electromagnet through the controller, so that the electromagnet generates magnetic force, and then utilizes the effect of like-sex repulsion on the side of the electromagnet close to the magnetic plate, so that the electromagnet generates a repulsive force on the magnetic plate, and then the magnetic plate and the sealing plate move under the repulsive force of the electromagnet, so as to block the lower end of the vent through the sealing plate, thereby preventing these flammable and explosive media from entering the inside of the machine body, which may cause the battery body and circuit board to explode, thereby improving the use effect of the device.

[0016] 2. The online detector with an explosion-proof structure further improves the sealing effect of the sealing plate and the vent by setting a sealing structure. Through the movement of the sealing plate, the extrusion plate of its side wall will contact and squeeze the air storage airbag, so that the air storage airbag is deformed and the gas inside it is added to the sealed airbag, so that the sealed airbag expands outward, thereby preventing flammable and explosive media from entering the interior of the body through the connecting gap between the sealing plate and the vent, further improving the use effect of the device.

[0024] Specifically, the protective structure 3 of the technical solution of the utility model includes: a fixing frame 31, a battery body 32, a vent 33, a dustproof net 34, a fixing plate 35, a sealing plate 36, an electromagnet 37, a magnetic plate 38, a reset spring 39, and a controller 310.

[0025] In one embodiment of the utility model, a protective structure 3 is provided to facilitate explosion-proof protection of the interior of the body 1. When using the device, the user can detachably connect the cover 6 to the upper end of the body 1, and then the user can conveniently carry the device to a designated location by holding the handle 14.

[0026] When the body 1 is located inside a flammable and explosive environment for detection, the user can first energize the electromagnet 37 through the controller 310, so that the electromagnet 37 generates a magnetic force, and then utilizes the effect of like-charge repulsion on the side of the electromagnet 37 close to the magnetic plate 38, so that the electromagnet 37 generates a repulsive force on the magnetic plate 38, and then the magnetic plate 38 and the sealing plate 36 of the side wall thereof move under the repulsive force of the electromagnet 37, and at this time the sealing plate 36 slides in a directional manner inside the directional opening 9 through the slide plate 10 fixedly connected at its upper end, so that the lower end of the vent 33 is blocked by the sealing plate 36, so as to prevent these flammable and explosive media from entering the body 1, which may cause the battery body 32 and the circuit board 5 to explode, thereby improving the use effect of the device, and the wiring holes 13 on the side walls of the device are plugged and fixed with the external wire body during normal use, so that the external gas will not enter the body 1 through the wiring holes 13.

[0027] In addition, by providing a sealing structure 4, the sealing effect of the sealing plate 36 and the vent 33 is further improved. When the sealing plate 36 moves, the extrusion plate 11 of the side wall will contact and squeeze the air storage bag 42, so that the side wall of the air storage bag 42 is deformed, so that the gas inside the air storage bag 42 is added to the sealing air bag 41 through two sets of ventilation pipes 43, so that the sealing air bag 41 expands outward, thereby preventing flammable and explosive media from entering the interior of the body 1 through the connecting gap between the sealing plate 36 and the vent 33, further improving the use effect of the device. Then the user can start the device for normal gas detection, and after leaving the environment, the user can return the sealing plate 36 to its original position.

[0028] Please continue reading Figure 1-Figure 5 The sealing structure 4 includes a sealing airbag 41 fixedly installed on four sides of the sealing plate 36, two groups of air storage airbags 42 are fixedly installed on both sides of the lower end of the support plate 7, the air storage airbag 42 and the sealing airbag 41 are connected by two groups of ventilation pipes 43, and directional openings 9 are opened on both sides of the lower end of the support plate 7. A slide plate 10 is fixedly installed on the lower end of the sealing plate 36, and the slide plate 10 is slidably connected to the inner wall of the directional opening 9. The interior of the air storage airbag 42 is in a state of being filled with gas, and the gas content in the sealing airbag 41 is one-half. The controller 310 is electrically connected to the electromagnet 37 through a wire, and a plurality of wiring holes 13 are opened on the side wall of the body 1, a handle 14 is fixedly installed on the upper end of the machine cover 6, an extrusion plate 11 is fixedly installed on the side wall of the sealing plate 36, and a plurality of fixed columns 12 are fixedly installed on the upper end of the circuit board 5, and the fixed columns 12 are detachably connected to the lower end of the support plate 7.

[0029] During operation, the user can conveniently carry the device to a designated location by holding the handle 14. When the body 1 is located in an inflammable and explosive environment for detection, the controller 310 is used to energize the electromagnet 37, and the electromagnet 37 and the magnetic plate 38 are close to each other on one side, so that the electromagnet 37 generates a repulsive force on the magnetic plate 38. Then, the magnetic plate 38 and the sealing plate 36 of its side wall move under the repulsive force of the electromagnet 37. The sealing plate 36 slides in a directional manner inside the directional port 9 through the slide plate 10, and the lower end of the vent 33 is blocked by the sealing plate 36, thereby avoiding these inflammable and explosive media. When the sealing plate 36 moves, the extrusion plate 11 on its side wall will contact and squeeze the air storage bag 42, causing the side wall of the air storage bag 42 to deform, so that the gas inside it is added to the sealing air bag 41 through two sets of ventilation pipes 43, so that the sealing air bag 41 expands outward, thereby preventing flammable and explosive media from entering the interior of the body 1 through the connecting gap between the sealing plate 36 and the vent 33. Then the user can start the device for normal gas detection. After leaving the environment, the user can return the sealing plate 36 to its original position.
