Description

Technical Field

[0001] This utility model relates to the detection of moving objects in special areas, specifically to an explosion-proof radar device suitable for explosion-proof sites. Background Technology

[0002] At vehicle entrances and exits in explosion-proof sites (Ex areas) such as petrochemical plants, oil and gas storage and transportation facilities, and hazardous chemical warehouses, the barrier gate system must have anti-smashing function, using radar to detect obstacles (vehicles, pedestrians) below the barrier gate to prevent the barrier arm from falling accidentally and causing accidents; in addition, the barrier gate must also meet explosion-proof requirements to ensure that internal circuit sparks do not ignite external explosive gases (such as IIC type).

[0003] As mentioned above, the radar at the barrier gate is usually positioned only towards the direction of oncoming vehicles, and cannot cover the direction of departure. In order for the radar to detect both directions simultaneously, the radar probe or the entire radar device is usually made movable so that it can rotate. However, in this way, the driving process of the movement mainly relies on the motor. As mentioned above, in the explosion-proof area, it is necessary to avoid the exposure of electrical sparks. During the operation of the motor, the internal carbon brushes are very likely to cause sparks, which will affect safety. Utility Model Content

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0032] Reference Figure 1-8 This utility model provides an explosion-proof radar device suitable for explosion-proof sites, including a base (fixed plate 1), an encapsulation part (mounting box 3), and a radar probe 6. Specifically:

[0033] During installation, the fixing plate 1 is used to fix the gate at a fixed position, and the mounting box 3 is rotatably connected to the fixing plate 1. The structure of the mounting box 3 is as follows: Figure 4 and Figure 7 As shown, it consists of a high-strength housing 301 and a transparent tempered glass 302. The radar probe 6 is fixedly installed inside the mounting box 3, with its light-sensing part facing the tempered glass 302, thereby ensuring normal transmission and reception of light signals.

[0034] Regarding the orientation of the radar probe 6, the mounting plate has a connecting post 2, and the back of the mounting box 3 has a protruding ear plate 4, which is rotatably connected to the connecting post 2, thereby enabling the mounting box 3 to be rotatable. Several elastic metal plates 9 are connected to the connecting post 2, which elastically resist the back of the mounting box 3, keeping the mounting box 3 in a fixed initial position under normal conditions, thus keeping the radar probe 6 in its initial orientation under normal conditions. An electromagnet 7 is also provided inside the mounting box 3, and a permanent magnet 8 is provided on the fixing plate 1. When the electromagnet 7 is magnetized, it attracts the permanent magnet 8, thereby driving the mounting box 3 to overcome the elastic force and twist, so as to adjust the orientation of the radar probe 6. There can be multiple combinations of electromagnet 7 and permanent magnet 8. Taking the figure as an example, two sets are shown, so that the mounting box 3 can be twisted in two directions.

[0035] Furthermore, to address when the mounting box 3 needs to be rotated to adjust the detection direction of the radar probe 6, this invention is also equipped with at least two noise sensors 10 (ZXHD / HS2110L type) for detecting sound vibrations. These sensors detect sound from two directions, corresponding to the sounds of vehicles approaching and leaving the barrier gate, respectively, to determine the presence of a vehicle or person. The noise sensors are connected to the electromagnets 7 via a 51 microcontroller. The microcontroller can control the action of the two electromagnets 7 based on the detection structure of the noise sensor 10, thereby controlling the rotation of the mounting box 3. The microcontroller can be integrated into the mounting box 3, and the noise sensors 10 can also be directly mounted and distributed on both sides.

[0036] Furthermore, for the power supply inside the entire mounting box 3, this utility model is also equipped with a conductive slip ring mechanism. The guide ring 11 is set on the connecting post 2, and the ear plate 4 has a hidden cavity 5 inside. The connecting post 2 is rotatably sealed through the hidden cavity 5, and the guide plate 12 is set in the hidden cavity 5, so that the entire conductive slip ring mechanism is in a sealed state. The external power supply line is arranged on the mounting plate and is connected to the guide ring 11 mechanism by embedding it inside the connecting post 2. The guide plate 12 can be directly connected to the inside of the mounting box 3 through the wire, thereby realizing the power supply needs inside the mounting box 3.

[0037] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
