Description

TECHNICAL FIELD

[0001] The utility model relates to mobile detection monitoring equipment technical field especially relates to a kind of fixing device for mobile detection monitoring equipment box. BACKGROUND

[0002] In many fields such as city security, traffic management, environmental monitoring, emergency rescue, mobile detection monitoring equipment box as the key carrier of integrated various detection instruments, monitoring equipment and data transmission module, its application is more and more widely, these equipment boxes often need to be deployed in outdoor complex environment, such as roadside, square edge, field operation area, etc., and may be flexibly moved and repositioned according to actual needs, which puts strict requirements on the fixing device of the equipment box.

[0003] The existing fixing device usually drives the clamping arm to tighten by motor when fixing the detection monitoring equipment box, and the locking is realized by the friction force between the clamping tool and the outer wall of the equipment box, so as to improve the stability of the equipment box during movement.

[0004] However, when the equipment box travels with the vehicle, the road bumps and sudden acceleration and deceleration conditions will produce continuous and irregular vibration, which is transmitted to the fixing device through the vehicle chassis. Because the clamping structure lacks effective buffer and shock absorption design, it will directly act on the equipment box body. Under the vibration impact, the contact part of the equipment box and the clamping tool is prone to local stress concentration, which causes the deformation of the box shell, the peeling of the paint surface, and even causes the loosening of the connecting screws, so that the precise detection elements inside the equipment box will fall off due to repeated vibration, and the display screen and other fragile components may also be displaced or broken due to resonance, thereby not only reducing the structural integrity and service life of the equipment box, but also affecting the running stability of the internal instruments. UTILITY MODEL CONTENTS

[0005] The utility model is through the effect of shock absorption and buffering assembly, which can quickly absorb part of impact energy through its elastic deformation, and weaken the transmission intensity of vibration, thereby effectively buffering and protecting the equipment box, reducing the damage of the equipment box shell caused by continuous vibration, thereby not only improving its structural integrity and service life, but also avoiding the problems of part loosening and parameter drift of internal precision instruments caused by vibration, and ensuring the stability of instrument operation, to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a fixing device for mobile detection monitoring equipment box, comprising a bottom plate;

[0007] The shock-absorbing and buffering assembly includes a tray and a magnetic shielding plate.

[0009] Preferably, a limiting box is fixedly installed on the top of the magnetic shielding plate, and a box door is fixedly installed on the top of the limiting box.

[0010] Preferably, the inner surface of the limiting box is adhesively connected with a silicone pad.

[0011] Preferably, a cooling assembly is provided on the top of the base plate;

[0012] The cooling assembly includes an air tank and a miniature fan. The bottom of the air tank is fixedly installed on the top of the base plate, and an air supply pipe is fixedly connected to the top of the air tank.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: Refer to Figure 1 - Figure 5 As shown: A fixing device for a mobile detection and monitoring equipment box, including a base plate 1;

[0027] The shock absorption and buffer assembly 2 includes a tray 201 and a magnetic shielding plate 205. A set of slots 202 are symmetrically opened on the top of the tray 201. A first permanent magnet 203 is provided on the inner wall of each slot 202. Guide sleeves 204 are fixedly installed on the top of the tray 201 near the four corners. A set of guide posts 206 are fixedly installed on the bottom of the magnetic shielding plate 205 near the four corners. The outer surface of the guide posts 206 is slidably connected to the inner wall of the guide sleeves 204. A set of second permanent magnets 207 are symmetrically fixedly installed on the bottom of the magnetic shielding plate 205. A triaxial accelerometer 208 is fixedly installed on the bottom of the magnetic shielding plate 205 near the center. The bottom of the tray 201 is fixedly connected to the top of the base plate 1. A limit box 209 is fixedly installed on the top of the magnetic shielding plate 205. A door 210 is fixedly installed on the top of the limit box 209. A silicone pad 211 is adhesively connected to the inner wall of the limit box 209.

[0028] In this embodiment, during the operation of the mobile detection and monitoring equipment fixing device, the first permanent magnet 203 inside the slot 202 is activated using an external controller, causing it to quickly enter the working state. Simultaneously, the second permanent magnet 207 is activated to ensure they are in a completely opposite state, preparing for subsequent magnetic force application. Then, the box door 210 is manually opened, and the equipment box is placed above the magnetic shielding plate 205. Since the first permanent magnet 203 and the second permanent magnet 207 have the same polarity, according to the principle of like poles repelling each other in physics, a continuous and stable repulsive force is generated between them. This repulsive force acts evenly on the magnetic shielding plate 205, allowing the magnetic shielding plate 205 to overcome its own weight and the weight of the equipment box, presenting a stable suspended state. Meanwhile, the magnetic shielding plate 205... 05 is made of a special alloy material with high magnetic permeability, playing a crucial role in the process. It effectively cuts off the propagation path of magnetic lines of force, preventing strong magnetic fields from causing magnetization, interference, or other adverse effects on the precision detection and monitoring equipment inside the equipment box, thus ensuring the normal operation of the equipment. Simultaneously, the guide post 206 slides within the corresponding guide sleeve 204. The surface of the guide post 206 undergoes special lubrication treatment, maintaining a minimal gap with the guide sleeve 204. When the vehicle vibrates due to uneven road surfaces during travel, the vibration is transmitted to the base plate 1 and the tray 201. With the combined action of the guide post 206 and the guide sleeve 204, the suspended equipment box is almost unaffected by this vibration, maintaining relative stability. Furthermore, the outer perimeter of the equipment box... The positioning box 209 is made of high-strength engineering plastic. Its inner edge maintains a reasonable gap with the equipment box, providing precise positioning and preventing excessive lateral or longitudinal displacement due to inertia during movement. The silicone pad 211 inside the positioning box 209 has good elasticity and toughness, uniform thickness, and a smooth surface, further providing all-around protection for the equipment box. When the equipment box experiences slight shaking, the silicone pad 211 absorbs the impact through its deformation, reducing direct collision and friction between the equipment box and the inner wall of the positioning box 209, preventing scratches or damage to the equipment box surface. During the entire movement process, when the transport vehicle encounters road bumps, sudden braking, or other situations, the silicone pad 211 installed at the bottom of the magnetic shield 205... The triaxial accelerometer 208 monitors the vibration and displacement of the equipment box in three-dimensional space in real time. When the sensor detects that the vertical vibration amplitude of the equipment box exceeds the preset safety range, it immediately converts the detected displacement data and direction information into an electrical signal and quickly transmits it to the external controller. After receiving the signal, the external controller precisely adjusts the drive of the permanent magnet according to the displacement direction. When the equipment box tends to fall due to bumps, the controller instantly increases the current input to the permanent magnet. According to the principle of electromagnetic induction, the increase in current can significantly enhance the repulsive force between the permanent magnets, thereby instantly increasing the levitation force on the magnetic shielding plate 205 and the equipment box, forming an upward thrust to prevent the equipment box from falling. When the equipment box tends to float upward due to inertia...The controller rapidly reduces the current, thus decreasing the repulsive force between the permanent magnets. At this point, the equipment box's own gravity plays a dominant role, forming a new balance with the weakened magnetic force. Through dynamic adjustment between gravity and magnetic force, excess energy generated by the impact is promptly offset, ensuring the equipment box remains in a stable suspended state. This prevents damage to internal equipment due to severe vibration. The shock-absorbing buffer component 2 can quickly absorb some of the impact energy through its elastic deformation, while simultaneously weakening the intensity of vibration transmission. This effectively provides shock absorption and buffer protection for the equipment box, reducing damage to the outer shell caused by continuous vibration. This not only improves its structural integrity and service life but also prevents problems such as loose parts and parameter drift in internal precision instruments due to vibration, ensuring the stability of instrument operation.

[0029] Example 2: According to Figure 1 - Figure 5 As shown: A cooling assembly 3 is installed on the top of the base plate 1;

[0030] The cooling assembly 3 includes an air tank 301 and a miniature fan 304. The bottom of the air tank 301 is fixedly installed on the top of the base plate 1. An air supply pipe 302 is fixedly connected to the top of the air tank 301. An air pump 303 is provided on the outer surface of the air supply pipe 302. One end of the air supply pipe 302 slides through the top of the door 210 and extends downwards. The bottom of the air pump 303 is fixedly installed on the top of the base plate 1. The top of the miniature fan 304 is fixedly installed on the bottom of the door 210.

[0031] In this embodiment, during the operation of the equipment box, the temperature sensor built into the limit box 209 monitors the internal temperature in real time. When the temperature reaches the preset value, it immediately sends a signal to the external controller. At this time, the external controller starts the air pump 303, which delivers the cooling gas in the air storage tank 301 to the inside of the limit box 209 through the air supply pipe 302, directly cooling the equipment box. At the same time, the micro fan 304 starts synchronously, which promotes the internal cold air to mix fully with the air and diffuse evenly. Under the action of the cooling component 3, the internal environment can be quickly and effectively cooled, thereby improving the operating efficiency of the instruments in the equipment box and ensuring that the internal precision components work stably at a suitable temperature.

[0032] Working principle: When operating the fixed device of the mobile detection and monitoring equipment, the first permanent magnet 203 in the slot 202 is activated first through the external controller, and the second permanent magnet 207 is activated and kept in a relative state. The box door 210 is opened and the equipment box is placed on the magnetic shielding plate 205. Due to the repulsion between the like poles of the two permanent magnets, the magnetic shielding plate 205 overcomes gravity and is suspended in the air. The magnetic shielding plate 205 is made of a high magnetic permeability alloy, which can block magnetic force and protect the internal equipment. The guide column 206 slides in the guide sleeve 204, which, together with the limit box 209 and the internal silicone pad 211, reduces vehicle vibration. To prevent the equipment box from shifting or being scratched, the triaxial accelerometer 208 at the bottom of the magnetic shield 205 monitors vibration in real time. When the vibration exceeds the safe range, it transmits a signal to the controller. The controller adjusts the current to change the magnetic force, balances gravity and repulsive force, and counteracts the impact energy. During the operation of the equipment box, the temperature sensor built into the limit box 209 monitors the temperature. When the temperature reaches the preset value, it triggers the external controller, starts the air pump 303, and sends the cooling gas from the air tank 301 into the limit box 209 through the air pipe 302. The micro fan 304 runs synchronously to ensure that the cool air is evenly diffused and to ensure the stable operation of the equipment.

[0033] By following the steps outlined above, you can complete the use of the fixed device for the mobile detection and monitoring equipment box.
