Description

Technical Field

[0001] The utility model belongs to the field of electric power equipment, and more specifically, relates to a fault monitoring device for electric power lines. Background Art

[0002] During the use of power lines, there are faults caused by line aging and other reasons. When problems occur in power lines, dangerous situations such as explosions are prone to occur. Therefore, it is necessary to monitor the power lines to ensure safe operation. At this time, fault monitoring equipment is needed.

[0003] However, when the fault monitoring equipment for power lines currently on the market is in use, dust and other impurities are easily introduced into the heat dissipation port area. As the dust and other impurities inside the fault monitoring equipment increase, it will directly affect the heat dissipation of the fault monitoring equipment. When the equipment is running, it will be affected by dust and other impurities and will also experience rapid temperature rise, which will cause the internal temperature of the equipment to be too high, thereby causing heat loss to the internal components of the equipment and reducing the service life of the equipment. To address this problem, existing fault monitoring equipment will be equipped with dust-proof components such as filters at the heat dissipation vents of the fault monitoring equipment.

[0004] For example, the patent document with Chinese patent application number: CN201621245309.8 and publication date: May 24, 2017 discloses a fault monitoring device for a power line, including a box body, the bottoms of the left and right sides of the box body are provided with wiring ports, the tops of the left and right sides of the box body are provided with vents, and the power generation device can provide the monitoring equipment with the power required for normal operation when the line in the box body fails and the power is cut off through the power generation device, the outer wall of the camera is provided with a ring-shaped LED light group, which is convenient for observing the working status of the electrical components inside the box body at night, and the vents can enhance the air flow in the inner cavity of the box body, which is convenient for the heat dissipation of the electrical components. At the same time, the inner cavity of the vents is provided with a filter to prevent dust or other debris from entering the box body through the vents, so as to avoid affecting the normal operation of the electrical components.

[0005] Another example is the Chinese patent application number: CN201920375409.X, the publication date: January 14, 2020, which discloses a heat dissipation mechanism of a power line fault monitoring device, including a power monitoring device body, a transmission rod fixedly connected to the back side of the power monitoring device body, a turntable fixedly connected to the back side of the transmission rod, and the front side of the transmission rod penetrates the back side of the power monitoring device body and is fixedly connected to the transmission plate. The utility model drives the connecting column to move left and right by rotating the movable rod in coordination with the rotating shaft, and the connecting column drives the baffle to move left and right while cooperating with the left and right limit movement of the slide groove, and the baffle starts the cooling fan while cooperating with the left and right limit movement of the slide rail, and similarly turns off the cooling, and a dust screen is fixedly installed on the surface of the cooling fan.

[0006] The power line fault monitoring devices of the above two solutions are both equipped with dust-proof mesh components to address the dust accumulation problem in the fault monitoring devices. However, after long-term use, such dust-proof mesh components will inevitably cause network ports to be clogged due to the adhesion of dust and debris, affecting the heat dissipation of the fault monitoring devices. Therefore, they need to be frequently disassembled for cleaning, which is more troublesome. Summary of the invention

DETAILED DESCRIPTION

[0031] Exemplary embodiments of the present invention are described in detail below. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from the spirit and scope of the present invention. The more detailed description of the embodiments of the present invention below is not intended to limit the scope of the claimed present invention, but is merely for illustration and does not limit the description of the features and characteristics of the present invention, in order to propose the best way to perform the present invention, and is sufficient to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0032] Example 1

[0033] Depend on Figure 1-3 As shown, a fault monitoring device for a power line includes a fault monitoring device body 1, which is used to monitor the power line. A retaining box 2 is installed at the side air outlet of the fault monitoring device body 1, and an assembly frame 3 is provided on the upper part of the retaining box 2 relative to the position of the air outlet of the fault monitoring device body 1.

[0034] The inner cavity of the retaining box 2 is installed with a motor 4, and a rotatable transmission rod 5 is installed at the output end of the motor 4. When the motor 4 is powered on, the transmission rod 5 can be driven to rotate. A circular positioning frame 6 is fixed to the outside of the transmission rod 5. When the transmission rod 5 rotates, the positioning frame 6 rotates accordingly. The inner cavity of the positioning frame 6 is divided into two assembly areas 7 of the same size, and the inner cavity of the assembly area 7 is installed with a filter screen 8 for blocking dust.

[0035] When the transmission rod 5 rotates to move one of the assembly areas 7 to the position of the assembly frame 3, the filter 8 inside the assembly area 7 corresponds to the air outlet on the fault monitoring device body 1, so that the filter 8 can block dust and other impurities from entering the air outlet, avoiding dust and other impurities from entering the fault monitoring device body 1 through the air outlet, ensuring that the fault monitoring device body 1 can effectively and stably dissipate heat, preventing the problem of rapid temperature rise caused by dust and other impurities entering the fault monitoring device body 1, and improving the service life of the fault monitoring device body 1. After the motor 4 is started, the positioning frame 6 can be driven to rotate through the transmission rod 5, so that when too much dust and other impurities adhere to the surface of one of the filter nets 8, a new filter net 8 can be automatically replaced, so that the air outlet on the fault monitoring device body 1 can be ensured to dissipate heat stably.

[0036] An annular mounting groove 9 is formed on the outer wall of the positioning frame 6, and a first sealing ring 10 is sleeved inside the mounting groove 9. After the mounting groove 9 and the first sealing ring 10 are sleeved, the positioning frame 6 is in direct contact with the inner wall of the retaining box 2 through the first sealing ring 10. Since the first sealing ring 10 is made of rubber material, and the rubber material has elastic properties, the first sealing ring 10 can produce an extrusion effect with the inner wall of the retaining box 2, and the two fit more closely. In this way, after the positioning frame 6 rotates, the first sealing ring 10 can be used to limit the position, so as to prevent the positioning frame 6 from rotating arbitrarily when there is no drive of the motor 4.

[0037] The surface of the retaining box 2 at the bottom of the assembly frame 3 is provided with an observation slot 11, through which the situation of the inner cavity at the bottom of the retaining box 2 can be directly viewed, and it is convenient for the user to inspect and clean the inside of the retaining box 2. The top of the observation slot 11 is connected to a closing cover 12 through a hinge transmission, and a second sealing ring 13 is bonded to the outer wall of the closing cover 12, and the closing cover 12 can be covered on the observation slot 11 for closing. At the same time, the second sealing ring 13 fits the inner wall of the observation slot 11, so that the stability of the closing cover 12 after covering the observation slot 11 can be achieved. A toggle rod 14 is fixed on the surface of the closing cover 12. When the observation slot 11 needs to be opened, it is only necessary to manually pull the toggle rod 14 outward to drive the closing cover 12 to move and separate from the observation slot 11.

[0038] like Figure 1-6 As shown, a buffer assembly 15 is installed in the inner cavity of the assembly area 7, and the buffer assembly 15 is connected to the filter 8. The filter 8 can move on the buffer assembly 15, so that it can be buffered after being hit by an object, avoiding direct damage after being hit. A dust removal mechanism 16 is installed at the bottom of the inner cavity of the retention box 2, and the dust removal mechanism 16 can automatically remove dust from the filter 8 to avoid the low efficiency of manual cleaning.

[0039] Specifically, the buffer assembly 15 includes a movable groove 151 provided on the inner wall of the assembly area 7, a slide bar 152 is fixed to the inner cavity of the movable groove 151, a first spring 153 is installed at one end of the slide bar 152, and one end of the slide bar 152 is movably connected to the outer portion of the filter screen 8. After the filter screen 8 is impacted, the filter screen 8 will move along the slide bar 152 and simultaneously squeeze the first spring 153. After being squeezed, the first spring 153 will first absorb the squeezing force and then release it. By utilizing the rebound function of the first spring 153, the filter screen 8 is repeatedly pushed and pulled, thereby effectively absorbing the impact force on the filter screen 8, thereby improving the protection and durability of the filter screen 8 when in use.

[0040] The dust removal mechanism 16 includes a fan 161 installed at the bottom of the retention box 2. After the fan 161 is powered on, the output end of the fan 161 is connected to the dust cover 162 through a hinge transmission. The fan 161 in the started state will use the squeezing force of the wind to push the dust cover 162 open, thereby making the input end and the output end of the fan 161 interlinked. The surface of the dust cover 162 facing the output end of the fan 161 is bonded with a soft magnet 163. The soft magnet 163 uses the principle of magnetic attraction to realize the dust cover 162 automatically closing the opening of the output end of the fan 161 after the fan 161 is turned off, thereby achieving the effect of preventing dust and other impurities. The fan 161 in the started state will absorb dust and other impurities on the surface of the filter screen 8 at the location of the inner cavity at the bottom of the retention box 2 through wind power, so that the filter screen 8 can be automatically cleaned.

[0041] A trapezoidal outlet groove 164 is provided at the bottom of the inner cavity of the retaining box 2. The bottom of the outlet groove 164 is connected to the input end of the fan 161. The absorbed dust and other impurities are guided to the input end of the fan 161 through the outlet groove 164, and then discharged through the output end of the fan 161. A steering rod 165 is fixed to the inner cavity of the outlet groove 164. A fan wheel 166 is movably installed in the middle of the steering rod 165. When the fan 161 is started, the absorbed airflow can drive the fan wheel 166 on the steering rod 165 to rotate synchronously. The rotating fan wheel 166 can loosen and dredge the dust and other impurities inside the outlet groove 164, so as to avoid blockage caused by excessive dust and other impurities inside the outlet groove 164.

[0042] In addition, the upper and lower ends of the assembly frame 3 are provided with telescopic grooves 17, and the inner cavity of the telescopic grooves 17 is movably sleeved with an extrusion rod 18, and a limiting block 19 is fixed in the middle of the extrusion rod 18. The two ends of the extrusion rod 18 located outside the limiting block 19 are movably installed with a second spring 20, and both ends of the extrusion rod 18 are installed with a positioning block 21 made of rubber material. The rotating impeller 166 can repeatedly squeeze the positioning block 21. When the positioning block 21 is squeezed, it will move upward using the extrusion rod 18. At this time, the extrusion rod 18 can cooperate with the limiting block 19 to drive the extrusion of the second spring 20, and the second spring 20 is used to reset the extrusion rod 18 after moving. In this way, as long as the impeller 166 is in a rotating state, it can repeatedly apply pressure to the extrusion rod 18 through the positioning block 21, so that the extrusion rod 18 repeatedly moves up and down. At this time, the positioning block 21 at the other end of the extrusion rod 18 repeatedly rubs the filter screen 8, thereby using the vibration generated by friction to more effectively remove dust from the surface of the filter screen 8, avoiding the inconvenience of cleaning caused by the strong adhesion of impurities such as dust.

[0043] In summary, in the power line fault monitoring device of the present embodiment, the structure of the dustproof component is improved, which effectively reduces the frequency of removing and cleaning the dustproof component, so that the device can be used for a long time.
