Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding cabinets, and in particular to a waterproof marine electromagnetic shielding cabinet. Background Technology

[0002] Electromagnetic shielding cabinets are used to house electronic communication equipment such as computers, servers, and switches. They prevent the electronic equipment from being affected by external electromagnetic interference during operation and can also isolate electromagnetic waves from harming the human body. They are suitable for use in situations where it is not appropriate to install an electromagnetic shielding room but protection of information equipment is required.

[0003] The announcement number CN208175238U discloses "A Novel Electromagnetic Shielding Cabinet", which includes a cabinet body. A cooling fan is fixedly connected to the bottom of the cabinet body. A ventilation duct is opened inside the cabinet body. A guide plate is fixedly connected inside the ventilation duct. One end of the ventilation duct is connected to a ventilation hole. A cooler is fixedly connected to the inner wall of the cabinet body. One end of the cooler is connected to a telescopic pipe. By setting up a cooler and a dryer, the cooler cools the inside of the cabinet body to prevent the internal temperature from being too high and damaging the electrical equipment. The dryer dries the inside of the cabinet body to prevent moisture. The cooling fan is set upward so that hot air can flow out from the top of the cabinet body more quickly, which can accelerate the heat dissipation rate and further extend the service life of the equipment inside the cabinet body. The ventilation hole is set horizontally to prevent dust from entering and also has a waterproof function, thereby achieving the purpose of good heat dissipation and dust removal effect.

[0004] Although the aforementioned novel electromagnetic shielding cabinet has certain advantages in heat dissipation, when the patent is applied to a marine environment, the ship will be affected by waves and wind during navigation, resulting in continuous vibration and occasional impact. Vibration and impact will affect the stability of the equipment inside the cabinet. Utility Model Content

A clamping structure 8 is installed on the right side of the upper end face of the insert plates 7. The clamping structure 8 includes a slide rail 81, a mounting plate 82, a rectangular plate 83, a handle 84, and a limiter. The positioning structure 85 and clamping plate 86 are provided. Mounting plates 82 are provided on both the front and rear sides of the slide rail 81. A rectangular plate 83 is installed on the upper surface of the mounting plate 82. A handle 84 is provided on the front side of the mounting plate 82. The rear end of the handle 84 passes through the mounting plate 82 and is connected to the limiting structure 85 for transmission. A clamping plate 86 is installed on the bottom left end of the limiting structure 85. The lower ends of the slide rail 81 and the mounting plate 82 are fixedly connected to the insert plate 7. There are two sets of clamping structures 8, which are symmetrically distributed to facilitate clamping and limiting the placed equipment. The outer wall of the handle 84 is provided with anti-slip texture to prevent the operator from slipping when turning the handle 4. A sponge pad 87 is installed on the left end of the clamping plate 86 to prevent wear when clamping the placed equipment.

[0023] Please see Figure 4-5This utility model provides a waterproof marine electromagnetic shielding cabinet. The limiting structure 85 includes a rack 851, a ratchet 852, a limiting shaft 853, a pawl 854, a limiting rod 855, a first connecting rod 856, a tension spring 857, and a second connecting rod 858. The rack 851 is meshed with the ratchet 852. The ratchet 852 is fitted onto the outer wall of the limiting shaft 853. One end of the limiting shaft 853 is rotatably connected to the mounting plate 82 via a bearing, and the other end of the limiting shaft 853 is drively connected to the handle 84. The upper teeth of the ratchet 852 are in contact with the pawl 854. The left end of the pawl 854 is rotatably connected to the limiting rod 855. Both the front and rear ends of the limiting rod 855 are installed and connected to the mounting plate 82. The front and rear end faces of the pawl 854 are each equipped with a first connecting rod 856. The first connecting rod 856 respectively... The first electromagnetic block 859 is connected to the second connecting rod 858 by tension spring 857, and the second connecting rod 858 is installed and connected to the inner side wall of the mounting plate 82. The lower side of the rack 851 is slidably engaged with the slide rail 81. The left end face of the rack 851 is installed and connected to the clamping plate 86. The right side of the upper end face of the pawl 854 is equipped with a first electromagnetic block 859. The upper side of the first electromagnetic block 859 is provided with a second electromagnetic block 8510, and the second electromagnetic block 8510 is installed on the lower end face of the rectangular plate 83. The first electromagnetic block 859 and the second electromagnetic block 8510 are magnetically connected, so that when energized, the second electromagnetic block 8510 can drive the first electromagnetic block 859 to move upward. The ends of the first connecting rod 856 and the second connecting rod 858 connected to the tension spring 857 are both provided with limit blocks 8511 to prevent the tension spring 857 from shifting and falling off.

[0024] The working principle is as follows:

[0025] First, place the new device in the desired location and connect the circuitry.

[0026] Secondly, by placing the equipment to be clamped and limited in the middle of the upper end face of the insert plate 7, the operator turns the handle 84, which drives the limiting shaft 853 to rotate. The limiting shaft 853 drives the ratchet 852 to rotate, and the ratchet 852 drives the rack 851 to move to the left along the slide rail 81. At the same time, the ratchet 852 can push the pawl 854 to rotate around the limiting rod 855. The tension spring 857 pulls the first connecting rod 856, so that the pawl 854 limits the ratchet 852 to rotate in one direction. The rack 851 drives the clamping plate 86 to move. Through the cooperation of the two sets of clamping structures 8, the two sets of clamping plates 86 clamp the placed equipment through the sponge pad 87, achieving the effect of stable clamping of the placed equipment. This avoids the problem of continuous vibration and occasional impact on the stability of the equipment caused by the influence of waves and wind during the voyage of the ship.

[0027] Third, the first electromagnetic block 859 and the second electromagnetic block 8510 are energized. The first electromagnetic block 859 is attracted by the second electromagnetic block 8510. The first electromagnetic block 859 drives the pawl 854 to move. While the pawl 854 rotates around the limiting rod 855, it pulls the tension spring 857 through the first connecting rod 856. The tension spring 857 extends, and the pawl 854 separates from the ratchet 852, releasing the limitation on the ratchet 852. At this time, the rack 851 can be moved to the right, which makes it easier to remove the device placed on the upper surface of the insert plate 7.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
