Description

Technical Field

[0001] The present invention relates to the technical field of communication auxiliary equipment, and in particular to a communication anti-signal interference equipment. Background Art

[0002] Communication system is a general term for technical systems used to complete the information transmission process. Communication systems are divided into wireless communication systems and wired communication systems. They are mainly realized by the propagation of electromagnetic waves in free space or the transmission mechanism in guided media. During the communication process of the communication system, it may be interfered by various conditions such as magnetic fields and noise, which in turn affects the transmission and reception of signals. Therefore, it is necessary to use anti-signal interference equipment.

[0003] At present, in the prior art, a Chinese patent with announcement number CN214626997U discloses an anti-interference device for a communication system. The device can achieve anti-interference for the wireless communication system and the wired communication device by setting up the antenna, the line inlet and the line outlet. At the same time, a detachable dust-proof net is set to facilitate the maintenance process of the device. Then, by combining the temperature sensor with the water-cooled heat dissipation device, the working efficiency of the water pump can be adjusted according to the situation while the device is effectively cooled. The device stops working when heat dissipation is not needed, thereby reducing energy consumption. However, during the actual use of the device, when the device is not in use, dust will continue to adhere to the dust-proof net and affect the subsequent ventilation and heat dissipation work. At the same time, moisture in the air will continue to enter the device, corroding the device and thus reducing the service life of the device.

One end of the housing 1 is fixedly connected with a fan blade 56. During use of the device, once the temperature in the housing 1 is higher than the value set by the temperature sensor 3, the controller controls the motor 52 to start, and the output shaft of the motor 52 rotates counterclockwise, driving the rotating shaft 53 to rotate counterclockwise, thereby driving the cam 55 and the fan blade 56 to rotate. The rotation of the fan blade 56 can discharge the hot air in the housing 1. At the same time, when the device is not in use, the temperature in the housing 1 will gradually decrease. When the temperature is lower than the value set by the temperature sensor 3, the controller controls the motor 52 to turn off and the fan blade 56 stops rotating.

[0037] Further, in order to enable the device to perform stable ventilation and heat dissipation, specifically, the L-plate 59 is fixedly connected to the inner wall of the shell 1, and a fixing block 58 is fixedly connected to the lower side of the L-plate 59. A telescopic card rod 57 is fixedly connected to the side of the fixing block 58 close to the rotating shaft 53. The telescopic card rod 57 is composed of a sleeve rod and an inner rod. The end of the inner rod away from the sleeve rod is wedge-shaped. The auxiliary positioning component 54 includes a fixing ring 541, and the fixing ring 541 is penetrated by the rotating shaft 53 and fixedly connected to the rotating shaft 53. The rotating shaft 53 penetrates the slip ring 1 542 and is slidably connected to the slip ring 1 542. The side of the slip ring 1 542 away from the fixing ring 541 is rotatably connected to the slip ring 2 543. The fixing ring 541 and The slip ring 1 542 is connected by an elastic telescopic rod 544, and the outer walls of the fixed ring 541 and the slip ring 1 542 are both hinged with a hinged rod 545, and the hinged rod 545 is hinged with a block 546. The slip ring 2 543 is sleeved on the outer wall of the rotating shaft 53, and the outer wall of the slip ring 2 543 is fixedly connected with a vertical rod 547, and the outer wall of the vertical rod 547 is hinged with a pull rod 548.

The pulley 65 and the steel rope 63 slide on the fixed pulley 65. A bayonet 611 is provided on the side of the slide bar 61 close to the telescopic card rod 57. The inner rod end of the telescopic card rod 57 matches the bayonet 611. A plurality of groups of protrusions 612 are fixedly connected to the outer wall of the slide bar 61. The plurality of groups of protrusions 612 are arranged in an equidistant array. The connecting block 62 is elastically connected to the L plate 59 through a return spring. The slide bar 61 penetrates the L plate 59 and is slidably connected to the L plate 59. When the rotating shaft 53 rotates counterclockwise to drive the cam 55 to rotate counterclockwise, the cam 55 squeezes the connecting block 62 to make the slide bar 61 slide downward. The connecting block 62 pulls the steel rope 63 to move, thereby driving the protective plate 64 to rotate on the outer wall of the shell 1. The sliding ring 542 is moved to open so that the heat dissipation port 101 can be exposed, so that the device can be ventilated and dissipated when in use. At the same time, during the rotation of the rotating shaft 53, the block 546 is pulled by the centrifugal force to move the hinged rod 545, so that the sliding ring 1 542 moves toward the direction of the fixed ring 541, compressing the telescopic end of the elastic telescopic rod 544. The sliding ring 1 542 slides to drive the sliding ring 2 543 to move, so that the vertical rod 547 drives the pulling rod 548 to pull the inner rod of the telescopic clamping rod 57 into the clamping slot 611, so that the sliding rod 61 is in a stable state, and the connecting block 62 and the protective plate 64 can be in a stable state, and will no longer affect the subsequent rotation of the cam 55.

[0038] Furthermore, when the device stops working, the temperature in the shell 1 will gradually decrease. When the temperature is lower than the value set by the temperature sensor 3, the controller controls the motor 52 to turn off and the fan blades 56 to stop rotating. At this time, the telescopic end of the elastic telescopic rod 544 is reset, driving the slip ring 1 542 and the slip ring 2 543 to reset, and then driving the pull rod 548 and the inner rod of the telescopic clamping rod 57 to reset, releasing the limit fixation of the slide rod 61, and allowing the connecting block 62 to reset under the action of the reset spring, and then the protective plate 64 is closed again, so as to block the heat dissipation port 101, prevent dust from adhering to the dustproof net 4, and at the same time prevent moisture in the outside air from entering the shell 1, thereby improving the service life of the device.

[0039] In the embodiment of the present invention, in order to enable the dust attached to the dustproof net 4 to be cleaned when the protective plate 64 blocks the dustproof net 4, specifically, the auxiliary cleaning component 7 includes a swing rod 71, an end of the swing rod 71 away from the protrusion 612 is fixedly connected to an elastic ball 74, a middle part of the swing rod 71 is hinged with a bracket 72, the swing rod 71 and the bracket 72 are elastically connected by a torsion spring, the top of the bracket 72 is fixedly connected to a support plate 73, the support plate 73 is fixedly connected to the outer wall of the mounting plate 51, and the elastic ball 74 is fixed to the dustproof net 4 conflict with each other, and the protrusion 612 descends during the descending process of the slide bar 61. During the descending process of the protrusion 612, the protrusion 612 squeezes the swing rod 71, causing the swing rod 71 to rotate around the hinge point of the bracket 72, compressing the torsion spring. After the protrusion 612 passes through the swing rod 71, under the resetting action of the torsion spring, the swing rod 71 drives the elastic ball 74 to reset, and the dustproof net 4 is knocked and vibrated, so that the dust attached to the dustproof net 4 during the working process of the device can be shaken off, thereby ensuring the subsequent good ventilation state of the dustproof net 4.

[0040] It should be noted that the above-mentioned electrical components are all existing technology products. Technical personnel in this field select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The applicant does not make specific restrictions here.

[0041] When in use, when the temperature in the housing 1 is higher than the value set by the temperature sensor 3, the controller controls the motor 52 to start, and the output shaft of the motor 52 rotates counterclockwise, driving the rotating shaft 53 to rotate counterclockwise, thereby driving the cam 55 and the fan blade 56 to rotate. During this process, the cam 55 squeezes the connecting block 62, causing the slide bar 61 to slide downward, and the connecting block 62 pulls the steel rope 63 to move, thereby driving the protective plate 64 to rotate and open on the outer wall of the housing 1, so that the heat dissipation port 101 can be exposed, so that the device can be ventilated and dissipated when in use;

[0042] At the same time, during the rotation of the rotating shaft 53, the block 546 is acted upon by the centrifugal force to pull the hinge rod 545 to move, and then the sliding ring 1 542 moves toward the direction of the fixed ring 541, compressing the telescopic end of the elastic telescopic rod 544, and the sliding ring 1 542 slides to drive the sliding ring 2 543 to move, so that the vertical rod 547 drives the pull rod 548 to pull the inner rod of the telescopic clamping rod 57 into the clamping port 611, so that the sliding rod 61 is in a stable state, and the connecting block 62 and the protective plate 64 can both be in a stable state;

[0043] At the same time, when the device is not in use, the temperature in the housing 1 will gradually decrease. When the temperature is lower than the value set by the temperature sensor 3, the controller controls the motor 52 to turn off, the fan blade 56 stops rotating, the telescopic end of the elastic telescopic rod 544 is reset, and the slip ring 1 542 and the slip ring 2 543 are reset, and then the pull rod 548 and the inner rod of the telescopic clamping rod 57 are reset, and the limit fixation of the slide rod 61 is released, so that the connecting block 62 is reset under the action of the reset spring, and then the protective plate 64 is closed again, so that the heat dissipation port 101 is shielded;

[0044] At the same time, as the slide bar 61 descends, the protrusion 612 descends. As the protrusion 612 descends, the protrusion 612 squeezes the swing rod 71, causing the swing rod 71 to rotate around the hinge point of the bracket 72, compressing the torsion spring. After the protrusion 612 passes through the swing rod 71, under the resetting action of the torsion spring, the swing rod 71 drives the elastic ball 74 to reset, knocking and vibrating the dustproof net 4, so that the dust attached to the dustproof net 4 during the operation of the device can be shaken off.
