Description

Technical Field

[0001] The invention relates to the technical field of outdoor cabinets for communication users, and in particular to a protective device for suppressing electromagnetic pollution of outdoor cabinets for communication users. Background Art

[0002] Communication refers to the exchange and transmission of information between people or between people and nature through certain behaviors or media. In a broad sense, it refers to the accurate and safe transmission of information from one party to another by any method and any media without violating their own will by two or more parties who need information. Existing communication users can use communication user outdoor cabinets to receive signals, thereby increasing the efficiency of information transmission. During the use of communication user outdoor cabinets, protective devices need to be used to protect the devices to prevent the devices from being damaged by the outside world. However, general protective devices have some disadvantages when used, such as:

[0003] When a general protective device is in use, the components inside the device will emit electromagnetic signals, thereby causing electromagnetic pollution. However, it is difficult for existing protective devices to eliminate electromagnetic pollution, and thus it is impossible to prevent the electromagnetic pollution from spreading outward, which in turn easily affects external components when the communication user outdoor cabinet is used. At the same time, when the communication user outdoor cabinet is in use, noise will be generated, and traditional protective devices can only isolate the noise but it is difficult to eliminate the noise, thus placing high requirements on the material of the protective device, which is not conducive to the production and use of the device. Summary of the invention

[0004] The object of the present invention is to provide a device for suppressing electromagnetic pollution of an outdoor cabinet of a communication user, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a communication user outdoor cabinet electromagnetic pollution protection device, comprising a cabinet and a door body, the door body is rotatably arranged at the side opening of the cabinet, the inner side of the cabinet and the interior of the door body are provided with a blocking layer, a fixed buffer support structure is arranged at the lower part of the interior of the cabinet, the inner side of the cabinet and the inner door body are provided with an inductive blocking structure, the interior of the inductive blocking structure is hollow, a heat sink is arranged on the outer side of the cabinet, and an exhaust heat dissipation mechanism is arranged at the upper end of the cabinet. When the device is in use, the exhaust heat dissipation mechanism works normally, so that the gas in the cabinet enters the interior of the cabinet through the inductive blocking structure, and then The gas is emitted to the outside by the exhaust heat dissipation mechanism. When the gas enters the inside of the device through the inductive blocking structure, the noise will be mixed in the air and flow inwards because the gas continuously impacts the inductive blocking structure. During the operation of the device, the noise generated by the device is mainly transmitted to the outside by the inductive blocking structure connected inside and outside, so that the noise transmitted to the outside is offset by the gas and noise flowing inwards, reducing the noise transmitted to the surroundings during the operation of the device. Since the noise transmitted upward by the exhaust heat dissipation mechanism is not directly transmitted to the surroundings, the noise transmitted by the exhaust heat dissipation mechanism is difficult to affect the surroundings, thereby avoiding the impact of excessive noise on the surroundings during the operation of the device;

[0006] When the device is in use, the electromagnetic force moving outward will be weakened by the blocking layer, thereby preventing the electromagnetic force from passing through the cabinet. When the magnetic force passes through the inductive blocking structure, since the outer side of the inductive blocking structure is surrounded by a spiral coil, when the magnetic force passes through the inductive blocking structure, according to the "reject what comes and leave what goes" principle in Lenz's law, an inductive magnetic force moving inward will be formed inside the inductive blocking structure to weaken the magnetic force moving outward, thereby preventing the sudden increase of the magnetic force from affecting external components. Since the current in the inductive blocking structure moves inward, it can be judged that the spiral coil will generate an inward current. Since the inward current is in opposite directions to the outward current, the magnetic fields generated by the two currents are opposite, so the two currents have an attractive force. When the outward current contacts the induced current, since the current directions of the two are opposite, part of the current will be offset, and the excess current will be converted into heat energy or move along the inductive blocking structure.

[0007] The cabinet can be opened by rotating the door, so that the components can be placed on the fixed buffer support structure inside the cabinet for installation, thereby using the fixed buffer support structure to provide buffer protection for the components.

[0008] Furthermore, the blocking layer includes a pad, a fixing hole and an interlayer, the pad is made of plastic material, an interlayer is provided inside the pad, and fixing holes for the movement of the induction blocking structure are evenly distributed inside the pad. When the device is in use, since the interlayer is provided inside the pad, when electricity or magnetic force continuously passes through the pad and the interlayer, the pad and the interlayer can effectively weaken the electromagnetic force, thereby avoiding the phenomenon of excessive electromagnetic force, and the fixing hole can ensure that the interlayer and the induction blocking structure are fitted together, thereby preventing the electricity and magnetic force generated by the device from moving outward through the gap between the induction blocking structure and the interlayer and flowing to the outside world.

[0009] Furthermore, the fixed buffer support structure includes a support platform, a locking hole and a fixed spring. The support platform is slidably arranged inside the cabinet. The locking holes are evenly distributed inside the support platform. The bottom of the support platform is connected to one end of the fixed spring, and the other end of the fixed spring is connected to the lower part of the interior of the cabinet. After the components are placed on the support platform, bolts can be used to pass through the components and the locking holes to connect the components to the support platform. When the device is in use, the fixed spring can buffer the support platform, thereby buffering the components to prevent the device from being damaged during use.

[0010] Furthermore, the induction blocking structure includes a fixed column, and the fixed column is slidably connected to the cabinet, the heat sink and the heat sink. A buffer pad is provided at one end of the fixed column located inside the cabinet, and the buffer pad is fit-connected to the internal components of the cabinet. When the device is in use, the fixed column and the buffer pad are connected to the internal components of the device. The buffer pad can buffer the fixed column and the components to prevent damage to the components. Since the fixed column and the components are fit together, the heat of the components can be directly transferred to the fixed column, thereby conducting heat to the components through the fixed column, thereby increasing the heat dissipation effect of the components inside the device.

[0011] Furthermore, a spiral fixing groove is provided on the side of the fixing column, an induction coil is arranged inside the fixing groove, two ends of the induction coil are respectively connected to the fixing column, a spiral fixing groove is provided in the fixing column, and the induction coil is embedded in the fixing groove, so the induction coil can be prevented from affecting the movement of the fixing column when the fixing column moves, and when the magnetic force passes through the fixing column, an induced current will be generated on the surface of the induction coil, and a corresponding induced magnetic force moving inward will be generated in the fixing column, so the magnetic force moving outward will be weakened, and at the same time, the induced current is opposite to the current moving inward and flowing outward, thereby attracting the current moving outward, so that the current moves to the fixing column and the induction coil, and when the electric energy moves to the fixing column, due to the large resistance of the fixing column, most of the current will be converted into heat energy, and a small part of the electric energy will continue to move outward along the fixing column.

[0012] Furthermore, a grounding wire is fitted and connected to the side of the fixing column, and the grounding wire is stored inside the heat sink. The lower ends of the heat sink and the grounding wire are parallel to the lower end of the cabinet. When the current moves along the fixing column and contacts the grounding wire, due to the good conductivity of the grounding wire, the current will flow into the inside of the grounding wire, and then flow downward along the grounding wire to the ground, thereby conducting electrical energy into the underground and avoiding the phenomenon of incidental charge on the surface of the device.

[0013] Furthermore, a first filter layer is provided on the internal thread of one end of the fixed column located outside the cabinet, and a support plate is provided on the outer side of the fixed column, the surface of the first filter layer is arc-shaped, and the arc-shaped end of the first filter layer is in the shape of a filter mesh. Since the fixed column and the heat sink are fitted and connected, the heat of the fixed column will be transferred to the heat sink, and the heat sink is in contact with the external gas, so the heat dissipation speed of the fixed column will be increased through the heat sink, and the interior of the cabinet is in a negative pressure state for a long time, so the external gas will flow into the interior of the cabinet through the fixed column to supplement the internal gas, and when the gas passes through the first filter layer, since the first filter layer is in the shape of a filter mesh, when the gas passes through the first filter layer, noise will be generated, and the noise will flow into the interior of the fixed column with the gas, and most of the noise generated by the components in the cabinet will also move outward along the fixed column, so that the noise from the outside to the inside and the noise moving outward from the inside of the device offset each other, thereby reducing the noise generated by the device during operation.

[0014] Furthermore, the exhaust heat dissipation mechanism includes an exhaust pipe, a fan and a second filter layer. The exhaust pipe is arranged on the top of the cabinet, and a fan is arranged inside the exhaust pipe. The upper end of the exhaust pipe is threadedly provided with a second filter layer in the shape of a filter mesh at the center. When the fan rotates, the gas in the cabinet will move outward, thereby forming a negative pressure in the cabinet, and the second filter layer can prevent external impurities from flowing into the interior of the cabinet along the second filter layer.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the present invention is in use, the exhaust heat dissipation mechanism works normally, so that the gas in the cabinet enters the interior of the cabinet through the inductive blocking structure, and then is emitted to the outside by the exhaust heat dissipation mechanism. When the gas enters the interior of the device through the inductive blocking structure, since the gas continuously impacts the inductive blocking structure, the noise will be mixed in the air and flow inwards. In the process of the device working, the noise generated by the device is mainly transmitted to the outside by the inductive blocking structure connected inside and outside, so that the noise transmitted to the outside is offset by the gas and noise flowing inwards, reducing the noise transmitted to the surroundings during the operation of the device. Since the noise transmitted upward by the exhaust heat dissipation mechanism is not directly transmitted to the surroundings, the noise transmitted by the exhaust heat dissipation mechanism is difficult to affect the surroundings, thereby avoiding the impact of excessive noise on the surroundings during the operation of the device.

[0016] When the device is in use, the electromagnetic force moving outward will be weakened by the blocking layer, thereby preventing the electromagnetic force from passing through the cabinet. When the magnetic force passes through the inductive blocking structure, since the outer side of the inductive blocking structure is surrounded by a spiral coil, according to the "reject what comes and stay what goes" principle in Lenz's law, an induced magnetic force moving inward will be formed inside the inductive blocking structure to weaken the magnetic force moving outward, thereby preventing the sudden increase of the magnetic force from affecting external components. Since the current in the inductive blocking structure moves inward, it can be determined that the spiral coil will generate an inward current. Since the inward current and the outward current are in opposite directions, the magnetic fields generated by the two currents are opposite, so the two currents have an attractive force. When the outward current contacts the induced current, since the currents are in opposite directions, part of the current will cancel each other out, and the excess current will be converted into heat energy or move along the inductive blocking structure.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2As shown, a communication user outdoor cabinet electromagnetic pollution protection device comprises a cabinet body 1 and a door body 2, the door body 2 is rotatably provided at the side opening of the cabinet body 1, a blocking layer is provided on the inner side of the cabinet body 1 and the inside of the door body 2, a fixed buffer support structure is provided at the lower part of the interior of the cabinet body 1, an inductive blocking structure is provided inside the side of the cabinet body 1 and the inside of the door body 2, the inside of the inductive blocking structure is hollow, a heat sink 9 is provided on the outside of the cabinet body 1, and an exhaust heat dissipation mechanism is provided at the upper end of the cabinet body 1. When the device is in use, the exhaust heat dissipation mechanism works normally, so that the gas in the cabinet body 1 enters the interior of the cabinet body 1 through the inductive blocking structure, and is then dissipated to the inside of the cabinet body 1 by the exhaust heat dissipation mechanism. Outside, when the gas enters the inside of the device through the inductive blocking structure, the noise will be mixed in the air and flow inwards due to the continuous impact of the gas on the inductive blocking structure. During the operation of the device, the noise generated by the device is mainly transmitted to the outside by the inductive blocking structure connected inside and outside, so that the noise transmitted to the outside is offset by the gas and noise flowing inwards, reducing the noise transmitted to the surroundings during the operation of the device. Since the noise transmitted upward by the exhaust heat dissipation mechanism is not directly transmitted to the surroundings, the noise transmitted by the exhaust heat dissipation mechanism is difficult to affect the surroundings, thereby avoiding the impact of excessive noise on the surroundings during the operation of the device;

[0029] like Figure 6 , Figure 7 and Figure 8 As shown, the electromagnetic force moving outward when the device is in use will be weakened by the blocking layer, thereby preventing the electromagnetic force from passing through the cabinet 1, and when the magnetic force passes through the inductive blocking structure, since the outer side of the inductive blocking structure is surrounded by a spiral coil, when the magnetic force passes through the inductive blocking structure, according to the "reject what comes and leave what goes" principle in Lenz's law, an inductive magnetic force moving inward will be formed inside the inductive blocking structure to weaken the magnetic force moving outward, thereby preventing the sudden increase of the magnetic force from affecting external components, and since the current in the inductive blocking structure moves inward, it can be judged that the spiral coil will generate an inward current, and since the inward current is opposite to the outward current in direction, the magnetic fields generated by the two currents are opposite, so the two currents have an attractive force, and when the outward current contacts the induced current, since the currents of the two are in opposite directions, part of the current will be offset, and the excess current will be converted into heat energy or move along the inductive blocking structure;

[0030] The cabinet 1 can be opened by rotating the door 2, so that the components can be placed on the fixed buffer support structure inside the cabinet 1 for installation, thereby using the fixed buffer support structure to provide buffer protection for the components.

[0031] like Figure 5As shown, the blocking layer includes a pad 6, a fixing hole 7 and an interlayer 8. The pad 6 is made of plastic material, and an interlayer 8 is provided inside the pad 6. The fixing holes 7 for the induction blocking structure to move are evenly distributed inside the pad 6. When the device is in use, since the interlayer 8 is provided inside the pad 6, when electricity or magnetic force continuously passes through the pad 6 and the interlayer 8, the pad 6 and the interlayer 8 can effectively weaken the electromagnetic force, thereby avoiding the phenomenon of excessive electromagnetic force, and the fixing hole 7 can ensure that the interlayer 8 and the induction blocking structure are fitted together, thereby preventing the electricity and magnetic force generated by the device from moving outward through the gap between the induction blocking structure and the interlayer 8 and flowing to the outside.

[0032] The fixed buffer support structure includes a support platform 3, a locking hole 4 and a fixed spring 5. The support platform 3 is slidably arranged inside the cabinet 1. The locking holes 4 are evenly distributed inside the support platform 3. The bottom of the support platform 3 is connected to one end of the fixed spring 5, and the other end of the fixed spring 5 is connected to the lower part of the interior of the cabinet 1. After the components are placed on the support platform 3, bolts can be used to pass through the components and the locking holes 4 to connect the components to the support platform 3. When the device is in use, the fixed spring 5 can buffer the support platform 3, thereby buffering the components to prevent the device from being damaged during use.

[0033] like Figure 3 As shown, the induction blocking structure includes a fixed column 10, and the fixed column 10 is slidably connected to the cabinet 1, the heat sink 9 and the heat sink 9. A buffer pad 13 is provided at one end of the fixed column 10 located inside the cabinet 1. The buffer pad 13 is fitted and connected to the internal components of the cabinet 1. When the device is in use, the fixed column 10 and the buffer pad 13 are connected to the internal components of the device. The buffer pad 13 can buffer the fixed column 10 and the components to prevent the components from being damaged. Since the fixed column 10 and the components are fitted together, the heat of the components can be directly transferred to the fixed column 10, so that the components are heat-conducted through the fixed column 10, thereby increasing the heat dissipation effect of the components inside the device.

[0034] A spiral fixing groove 11 is provided on the side of the fixing column 10, and an induction coil 12 is arranged inside the fixing groove 11. Both ends of the induction coil 12 are connected to the fixing column 10 respectively. A spiral fixing groove 11 is provided inside the fixing column 10, and the induction coil 12 is embedded inside the fixing groove 11, so that the induction coil 12 can be prevented from affecting the movement of the fixing column 10 when the fixing column 10 moves. When the magnetic force passes through the fixing column 10, an induced current will be generated on the surface of the induction coil 12, and an induced magnetic force moving inward will be generated in the fixing column 10 accordingly, so the magnetic force moving outward will be weakened. At the same time, the induced current is opposite to the current moving inward and flowing outward, thereby attracting the current moving outward, so that the current moves to the fixing column 10 and the induction coil 12. When the electric energy moves to the fixing column 10, due to the large resistance of the fixing column 10, most of the current will be converted into heat energy, and a small part of the electric energy will continue to move outward along the fixing column 10.

[0035] like Figure 4 As shown, the side of the fixing column 10 is fitted with a grounding wire 14, and the grounding wire 14 is stored inside the heat sink 9. The lower ends of the heat sink 9 and the grounding wire 14 are parallel to the lower end of the cabinet 1. When the current moves along the fixing column 10 and contacts the grounding wire 14, due to the good conductivity of the grounding wire 14, the current will flow into the inside of the grounding wire 14, and then flow downward along the grounding wire 14 to the ground, thereby conducting electrical energy into the ground to avoid the phenomenon of incidental charge on the surface of the device.

[0036] The first filter layer 16 is provided on the inner thread of one end of the fixing column 10 located outside the cabinet 1, and a support plate 15 is provided on the outer side of the fixing column 10. The surface of the first filter layer 16 is arc-shaped, and the arc-shaped end of the first filter layer 16 is in the shape of a filter mesh. Since the fixing column 10 and the heat sink 9 are closely connected, the heat of the fixing column 10 will be transferred to the heat sink 9, and the heat sink 9 is in contact with the external gas, so the heat dissipation speed of the fixing column 10 will be increased through the heat sink 9, and the interior of the cabinet 1 is in a negative pressure state for a long time, so the external gas will The gas flows into the interior of the cabinet 1 through the fixed column 10 to replenish the internal gas. When the gas passes through the first filter layer 16, since the first filter layer 16 is in the shape of a filter mesh, noise will be generated when the gas passes through the first filter layer 16. The noise will flow into the interior of the fixed column 10 along with the gas, and most of the noise generated by the components in the cabinet 1 will also move outward along the fixed column 10, so that the noise from the outside to the inside and the noise moving outward from the inside of the device cancel each other out, thereby reducing the noise generated by the device during operation.

[0037] The exhaust heat dissipation mechanism includes an exhaust pipe 17, a fan 18 and a second filter layer 19. The exhaust pipe 17 is arranged at the top of the cabinet 1. The fan 18 is arranged inside the exhaust pipe 17. The upper end of the exhaust pipe 17 is threaded with a second filter layer 19 in the shape of a filter mesh at the center. When the fan 18 rotates, the gas in the cabinet 1 will move outward, thereby forming a negative pressure in the cabinet 1, and the second filter layer 19 can prevent external impurities from flowing into the interior of the cabinet 1 along the second filter layer 19.

[0038] Working principle of the present invention: when the device is in use, the exhaust heat dissipation mechanism works normally, so that the gas in the cabinet 1 enters the interior of the cabinet 1 through the inductive blocking structure, and then is emitted to the outside by the exhaust heat dissipation mechanism. When the gas enters the interior of the device through the inductive blocking structure, since the gas continuously impacts the inductive blocking structure, the noise will be mixed in the air and flow inwards. In the process of the device working, the noise generated by the device is mainly transmitted to the outside by the inductive blocking structure connected inside and outside, so that the noise transmitted to the outside is offset by the gas and noise flowing inwards, reducing the noise transmitted to the surroundings during the operation of the device. Since the noise transmitted upward by the exhaust heat dissipation mechanism is not directly transmitted to the surroundings, the noise transmitted by the exhaust heat dissipation mechanism is difficult to affect the surroundings, thereby avoiding the impact of excessive noise on the surroundings when the device is running;

[0039] When the device is in use, the electromagnetic force moving outward will be weakened by the blocking layer, thereby preventing the electromagnetic force from passing through the cabinet 1. When the magnetic force passes through the inductive blocking structure, since the outer side of the inductive blocking structure is surrounded by a spiral coil, when the magnetic force passes through the inductive blocking structure, according to the "reject what comes and leave what goes" principle in Lenz's law, an induced magnetic force moving inward will be formed inside the inductive blocking structure to weaken the magnetic force moving outward, thereby preventing the sudden increase of the magnetic force from affecting external components. Since the current in the inductive blocking structure moves inward, it can be determined that the spiral coil will generate an inward current. Since the inward current and the outward current are in opposite directions, the magnetic fields generated by the two currents are opposite, so the two currents have an attractive force. When the outward current contacts the induced current, since the currents are in opposite directions, part of the current will cancel each other out, and the excess current will be converted into heat energy or move along the inductive blocking structure.
