Description

Technical Field

[0001] This invention belongs to the field of electrical safety equipment, and in particular relates to an intelligent detection and early warning device for safe electricity use. Background Technology

[0002] With the continuous establishment of ultra-high voltage and extra-high voltage transmission lines in my country, the AC transmission network above 750 kV is developing towards full coverage. To facilitate intelligent management, an online monitoring and early warning system for safe electricity use that can monitor in real time has emerged. It realizes basic model and data sharing, mutual transmission of monitoring alarms in safe areas, unified display of monitoring information, and unified processing, analysis, and judgment of equipment electrical quantities and status data. It provides monitors with comprehensive monitoring functions for safe electricity use status.

[0003] However, existing intelligent detection and early warning devices for safe electricity use still have the following problems:

[0004] Since power transmission lines are located outdoors, and the intelligent power safety detection and early warning device needs to be installed near the terminal of the power transmission line, it will also be installed outdoors. However, the outdoor environment is usually very harsh, with a lot of dust flying around. When the intelligent power safety detection and early warning device is working, its internal electronic components will generate a lot of heat. Therefore, it is necessary to reserve heat dissipation holes on the housing of the intelligent power safety detection and early warning device and install a cooling fan to dissipate the heat. When the cooling fan draws in the outside cold air, the floating dust will also enter the interior of the intelligent power safety detection and early warning device with the air.

[0005] When dust accumulates on electrical components and the inner walls of the enclosure, it reduces the enclosure's heat dissipation efficiency, causing the internal temperature to rise and potentially burning out the components. Furthermore, dust easily forms charged particles and may absorb moisture from the air, leading to a decrease in the insulation performance of components and increasing the risk of short circuits and grounding faults. Dust can also corrode electrical components and accelerate the aging of the wiring sheath, which is detrimental to the long-term use of the intelligent electrical safety detection and early warning device. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent detection and early warning device for safe electricity use, which aims to solve the technical problem in the prior art where dust entering the intelligent detection and early warning device for safe electricity use causes damage to its internal electronic components.

[0007] This invention is implemented as follows: a smart detection and early warning device for safe electricity use includes a housing. A door is hinged to the front side of the housing. Air inlets are provided on both the left and right sides of the housing. A partition is fixedly connected to the top of the housing. Heat dissipation holes are provided on the sides of the partition. A rain cover is fixedly installed on the top of the partition. A cooling fan is installed inside the partition, and the exhaust port of the cooling fan is connected to the interior of the housing. A control and early warning component is installed inside the housing. This control and early warning component is used to detect and control power transmission lines. When a short circuit, open circuit, current overload, or high temperature occurs in the power transmission line, the control and early warning component can automatically cut off the current to the power transmission line and transmit the information to the user's mobile terminal via a wireless module, so that the user can promptly inspect and repair it. This control and early warning component is existing technology and will not be described in detail here.

[0008] The housing also has two mounting cavities, each of which is equipped with a dust removal mechanism. The input end of the dust removal mechanism is connected to the air inlet, and the output end of the dust removal mechanism is connected to the interior of the housing. The dust removal mechanism is used to remove dust from the air entering the housing, so as to prevent dust from falling on the control and early warning components and causing damage to the control and early warning components, and to extend the service life of the control and early warning components.

[0009] A cover plate is installed on the side of the mounting cavity by screws to seal the mounting cavity and prevent air leakage from the side of the mounting cavity.

[0010] Further technical solution: The dust removal mechanism includes a partition fixedly installed in the installation cavity. The partition divides the installation cavity into a purification air duct, a baffle air duct, and a return air duct. The purification air duct is connected to the air inlet. The purification air duct, the baffle air duct, and the return air duct form an inverted U-shaped air duct. An air outlet is provided on the side of the installation cavity near the middle of the box.

[0011] The dust removal mechanism also includes an electrostatic dust removal component, which is installed inside the purification duct and is used to remove dust from the air passing through the purification duct.

[0012] Further technical solution: The electrostatic dust removal assembly includes two drive rollers rotatably installed in the purification air duct, and an annular insulating strip is connected between the two drive rollers. The surface of the annular insulating strip is embedded with metal foil.

[0013] An insulating plate is fixedly installed on the side wall of the purification air duct, and a cathode plate is fixedly installed on the side of the insulating plate. The cathode plate is electrically connected to the negative electrode, and the metal foil is electrically connected to the positive electrode.

[0014] Since the metal foil is in a rotating state, in order to achieve a stable electrical connection of the metal foil, the electrostatic dust removal assembly also includes a mounting block. The mounting block is installed inside the purification air duct. An electrode block is fixedly installed at the bottom of the mounting block. The electrode block abuts against the top of the metal foil and is electrically connected to the positive terminal of the power supply.

[0015] Further technical solution: The dust removal mechanism also includes a knocking component and a collecting component. The knocking component is installed inside the return air duct. One end of the knocking component extends into the interior of the purification air duct and can contact the surface of the metal foil. The knocking component is used to knock the dust off the surface of the metal foil.

[0016] The collection component is installed below the tapping component and is used to collect the dust knocked off the metal foil.

[0017] Further technical solution: The striking assembly includes a fixed rod fixedly installed inside the purification air duct, a rotating cylinder rotatably installed on the fixed rod, an upper vertical rod and a lower vertical rod fixedly connected to the upper and lower sides of the rotating cylinder respectively, a crossbeam fixedly connected to the end of the upper vertical rod, and multiple striking heads fixedly connected to the side of the crossbeam through a connecting rod, the striking heads contacting the surface of the metal foil, and a push ball fixedly connected to the end of the lower vertical rod;

[0018] The tapping assembly also includes a rotating column rotatably installed inside the return air duct. One end of the rotating column extending into the purification air duct is fixedly connected to a plurality of triangular push rods that cooperate with the push ball. A plurality of equally spaced rotating blades are fixedly connected to the circumferential side of the rotating column. The rotating column is located above the air outlet.

[0019] Further technical solution: The collection component includes a collection box, which is installed below the metal foil, and the bottom of the purification air duct has a first dust collection hole communicating with the collection box.

[0020] A further technical solution: a filter screen is installed inside the air outlet;

[0021] To prevent the filter screen from being clogged by dust, a cleaning brush is provided on the side of the rotating blade, and the cleaning brush is in contact with the surface of the filter screen.

[0022] To treat the dust in the return air duct, a second dust collection hole is provided at the bottom of the return air duct. A funnel-shaped dust guide hopper is fixedly installed inside the second dust collection hole. One end of the collection box extends below the dust guide hopper, and a partition plate is provided inside the collection box. The partition plate separates the purification air duct and the return air duct, preventing air in the purification air duct from directly entering the return air duct from the collection box, thus avoiding a reduction in the dust removal effect.

[0023] A further technical solution: The mounting block is slidably installed inside the purification air duct, and an adjusting screw is rotatably installed inside the purification air duct, the adjusting screw being threadedly connected to the mounting block.

[0024] Further technical solution: The dust removal mechanism also includes a windbreak structure, the windbreak structure includes a windbreak plate fixedly installed on the partition, and a friction strip is fixedly installed at the bottom of the windbreak plate, the bottom of the friction strip being in contact with the surface of the metal foil.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. This invention, by setting two dust removal mechanisms connected to the air inlet, can remove dust from the air entering the housing, preventing dust from falling onto the control and early warning components and causing damage to them, thus extending the service life of the control and early warning components;

[0027] 2. In this invention, by setting the anode as a transmission roller, an annular insulating belt, and a metal foil, the anode can be rotated by a servo motor, thereby rotating the metal foil area with attached dust to other places, avoiding excessive dust accumulation that would reduce the dust removal effect.

[0028] 3. The present invention, by setting a knocking component and a collecting component, can knock off the dust on the surface of the metal foil and collect the dust, so as to avoid excessive dust accumulation on the surface of the metal foil, which would affect the subsequent dust adhesion effect.

[0029] 4. This invention, by setting up a striking head, rotating column, triangular push rod, rotating blade, rotating cylinder, etc., during the process of air entering the return air duct and flowing towards the air outlet, the air will drive the rotating column to rotate through the rotating blade, the rotating column will drive the triangular push rod to rotate, and the triangular push rod will drive the striking head away from the surface of the metal foil. Then, under the action of gravity, the striking head will quickly strike the surface of the metal foil, knocking off the dust on the surface of the metal foil. This process does not require a special driving device, reducing the production cost of the device.

[0030] 5. In this invention, by setting an adjusting screw and threading it to the mounting block, when oxidation occurs at the metal foil part in contact with the electrode block, the adjusting screw can be rotated. The adjusting screw drives the mounting block and the electrode block to move, which can move the electrode block to other areas of the metal foil, thereby allowing the metal foil to make good contact with the electrode block again and avoiding unstable electrical connection.

[0031] 6. In this invention, by setting up a baffle plate and a friction strip, the combination of the baffle plate and the friction strip blocks the gap at the top of the metal foil, preventing air from entering the space between the metal foil and the partition plate. This allows all the air to pass through the space between the cathode plate and the metal foil, improving the dust removal effect. In addition, the friction strip also rubs the surface of the metal foil, thereby polishing away the oxide layer on the surface of the metal foil, improving the contact between the metal foil and the electrode block, and extending the service life of the metal foil. Finally, the friction strip intercepts the dust on the surface of the metal foil, sweeping away the dust that the knocking component cannot remove, improving the adhesion and utilization rate of dust on the surface of the metal foil, and improving the dust removal effect.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] like Figures 1-7 As shown, this invention provides an intelligent detection and early warning device for safe electricity use, comprising a housing 3, a door 1 hinged to the front side of the housing 3, air inlets 2 on both the left and right sides of the housing 3, a surrounding panel 7 fixedly connected to the top of the housing 3, heat dissipation holes 8 on the side of the surrounding panel 7, a rain cover 4 fixedly installed on the top of the surrounding panel 7, a cooling fan 9 installed inside the surrounding panel 7, the exhaust port of the cooling fan 9 communicating with the interior of the housing 3, and a control and early warning component 6 installed inside the housing 3. The control and early warning component 6 is used to detect and control power transmission lines. When a short circuit, open circuit, current overload, or high temperature occurs in the power transmission line, the control and early warning component 6 can automatically cut off the current to the power transmission line and transmit the information to the user's mobile terminal via a wireless module so that the user can check and repair it in time. This control and early warning component 6 is prior art and will not be described in detail here.

[0043] The housing 3 also has two mounting cavities inside, and each mounting cavity is equipped with a dust removal mechanism 5. The input end of the dust removal mechanism 5 is connected to the air inlet 2, and the output end of the dust removal mechanism 5 is connected to the interior of the housing 3. The dust removal mechanism 5 is used to remove dust from the air entering the housing 3, so as to prevent dust from falling on the control and early warning components 6 and causing damage to the control and early warning components 6, and to extend the service life of the control and early warning components 6.

[0044] A cover plate 51 is installed on the side of the mounting cavity by screws to seal the mounting cavity and prevent air leakage from the side of the mounting cavity.

[0045] Specifically, the control and early warning component 6 can also integrate an AI module, which can intelligently monitor and regulate the current of the transmission line through AI, and send the information to the mobile terminal through the communication module. It can be monitored in real time through portable devices and operated in the background in the first instance, so that users can keep abreast of the on / off status of each circuit, clearly understand the power consumption of each line, and avoid overload operation.

[0046] Meanwhile, the detection module monitors electricity consumption in real time, providing data support for energy conservation and emission reduction; by monitoring the working status of switches, faulty switches can be detected in a timely manner, avoiding safety accidents caused by switch failures.

[0047] Given the unpredictable nature of electricity usage at construction sites, managers can remotely monitor the operation of distribution boxes via mobile phones and computers, flexibly setting the switching times of the distribution boxes. This allows them to remotely adjust the switching times according to construction needs, avoiding safety hazards associated with manual operation.

[0048] You can also use your mobile phone to turn off all the switches in the distribution box with one click. In case of emergencies or dangerous events, it can automatically sound an alarm and push the alarm information to the mobile phone backend. It can remotely cut off the power supply at the first time to maximize the safety of personnel and equipment.

[0049] The present invention provides a safe electricity intelligent detection and early warning device. In this embodiment, the dust removal mechanism 5 includes a partition 53 fixedly installed in the installation cavity. The partition 53 divides the installation cavity into a purification air duct 55, a baffle air duct 52 and a return air duct 54. The purification air duct 55 is connected to the air inlet 2. The purification air duct 55, the baffle air duct 52 and the return air duct 54 form an inverted U-shaped air duct. An air outlet is opened on the side of the installation cavity near the middle of the box body 3.

[0050] The dust removal mechanism 5 also includes an electrostatic dust removal component 56, which is installed inside the purification duct 55 and is used to remove dust from the air passing through the purification duct 55.

[0051] Specifically, the cooling fan 9 draws air from the housing 3. Under negative pressure, outside air enters the purification duct 55 through the air inlet 2. After the electrostatic dust removal component 56 removes dust from the air, the clean air passes through the baffle duct 52 and the return duct 54 in sequence, and enters the housing 3 through the air outlet. Then the air is drawn out by the cooling fan 9. At the same time, the cold air carries away the heat of the control and early warning component 6 and is discharged from the housing 3 through the heat dissipation hole 8.

[0052] The present invention provides an intelligent detection and early warning device for safe electricity use. In this embodiment, the electrostatic dust removal component 56 includes two transmission rollers 565 rotatably installed in the purification air duct 55. An annular insulating strip 564 is connected between the two transmission rollers 565. The surface of the annular insulating strip 564 is embedded with a metal foil 563. A servo motor 569 is fixedly installed on the housing 3. The output shaft of the servo motor 569 is fixedly connected to one end of one transmission roller 565.

[0053] An insulating plate 562 is fixedly installed on the side wall of the purification air duct 55. A cathode plate 561 is fixedly installed on the side of the insulating plate 562. The cathode plate 561 is electrically connected to the negative electrode, and the metal foil 563 is electrically connected to the positive electrode.

[0054] Since the metal foil 563 is in a rotating state, in order to achieve a stable electrical connection of the metal foil 563, the electrostatic dust removal assembly 56 also includes a mounting block 567. The mounting block 567 is installed inside the purification air duct 55. An electrode block 568 is fixedly installed at the bottom of the mounting block 567. The electrode block 568 abuts against the top of the metal foil 563 and is electrically connected to the positive terminal of the power supply.

[0055] Specifically, the metal foil 563 is made of a metal with good conductivity and toughness, such as copper, and the electrode block 568 is made of a conductive metal with high strength, good wear resistance and not easy to oxidize, such as chromium zirconium copper (CuCrZr) and beryllium copper (BeCu).

[0056] When energized, an electric field is formed between the cathode plate 561 and the metal foil 563. The electric field ionizes the surrounding air molecules, generating a large number of free electrons and positive ions. These free electrons move rapidly toward the metal foil 563, colliding with dust particles in the air along the way and attaching to the dust, thus making the dust particles negatively charged. Due to the Coulomb force, the negatively charged dust particles are strongly attracted in the electric field and move toward the electrode with the opposite polarity—that is, the positive electrode (metal foil 563). After the dust particles reach the surface of the metal foil 563, they release the charge and deposit and accumulate on the surface of the metal foil 563, thereby achieving dust removal from the air.

[0057] Then, the servo motor 569 drives the transmission roller 565 to rotate, and the transmission roller 565 drives the metal foil 563 to rotate counterclockwise, which can rotate the area of ​​the metal foil 563 with attached dust to other places, avoiding excessive dust accumulation and reducing the dust removal effect.

[0058] The present invention provides a safe electricity intelligent detection and early warning device. After too much dust accumulates on the surface of the metal foil 563, it will affect the adhesion effect of subsequent dust, so that some dust may still enter the housing 3 with the air flow. Therefore, in this embodiment, the dust removal mechanism 5 also includes a knocking component 58 and a collecting component 59. The knocking component 58 is installed inside the return air duct 54. One end of the knocking component 58 extends into the interior of the purification air duct 55 and can contact the surface of the metal foil 563. The knocking component 58 is used to knock the dust off the surface of the metal foil 563.

[0059] The collecting component 59 is installed below the striking component 58 and is used to collect dust knocked off the metal foil 563.

[0060] The present invention provides an intelligent detection and early warning device for safe electricity use. In this embodiment, the striking component 58 includes a fixed rod 588 fixedly installed inside the purification air duct 55. A rotating cylinder 589 is rotatably installed on the fixed rod 588. An upper vertical rod 587 and a lower vertical rod 5810 are fixedly connected to the upper and lower sides of the rotating cylinder 589, respectively. A crossbeam 584 is fixedly connected to the end of the upper vertical rod 587. A plurality of striking heads 586 are fixedly connected to the side of the crossbeam 584 through a connecting rod 585. The striking heads 586 are in contact with the surface of the metal foil 563. A push ball 5811 is fixedly connected to the end of the lower vertical rod 5810.

[0061] The tapping assembly 58 also includes a rotating column 582 rotatably installed inside the return air duct 54. One end of the rotating column 582 extending into the purification air duct 55 is fixedly connected to a plurality of triangular push rods 5812 that cooperate with the push ball 5811. A plurality of equally spaced rotating blades 581 are fixedly connected to the circumferential side of the rotating column 582. The rotating column 582 is located above the air outlet.

[0062] Specifically, as air enters the return air duct 54 and flows towards the air outlet, the air drives the rotating column 582 to rotate via the rotating blade 581. The rotating column 582 drives the triangular push rod 5812 to rotate, which in turn drives the push ball 5811 and the lower vertical rod 5810 to rotate. The lower vertical rod 5810 drives the rotating cylinder 589, the upper vertical rod 587, and the striking head 586 to rotate. According to the lever principle, the striking head 586 moves away from the surface of the metal foil 563. When the triangular push rod 5812 passes the push ball 5811, the striking head 586 strikes the surface of the metal foil 563 rapidly under the action of gravity. Under the action of vibration, the dust on the surface of the metal foil 563 is knocked off and falls into the collection component 59.

[0063] The present invention provides a smart detection and early warning device for safe electricity use. In this embodiment, the collection component 59 includes a collection box 594, which is installed below the metal foil 563. The bottom of the purification air duct 55 is provided with a first dust collection hole 592 that communicates with the collection box 594.

[0064] Specifically, the dust knocked down by the tapping head 586 will fall into the collection box 594 through the first dust collection hole 592.

[0065] The present invention provides a safe electricity intelligent detection and early warning device. In order to improve the dust removal effect of the dust removal mechanism 5, in this embodiment, a filter screen 57 is provided in the air outlet.

[0066] To prevent the filter screen 57 from being clogged by dust, a cleaning brush 583 is provided on the side of the rotating blade 581, and the cleaning brush 583 contacts the surface of the filter screen 57.

[0067] To treat the dust in the return air duct 54, a second dust collection hole is provided at the bottom of the return air duct 54. A funnel-shaped dust guide hopper 591 is fixedly installed inside the second dust collection hole. One end of the collection box 594 extends below the dust guide hopper 591, and a partition plate 593 is provided inside the collection box 594. The partition plate 593 separates the purification air duct 55 and the return air duct 54 to prevent air in the purification air duct 55 from directly entering the return air duct 54 from the collection box 594, thus avoiding a reduction in the dust removal effect.

[0068] Specifically, the funnel-shaped dust guide hopper 591 is wider at the top and narrower at the bottom, allowing dust to fall smoothly into the collection box 594 and preventing it from easily escaping. This avoids excessive dust accumulation in the return air duct 54, which could affect the ventilation of the filter 57.

[0069] The present invention provides an intelligent detection and early warning device for safe electricity use. Due to frictional heat generation, the surface of the metal foil 563 is easily oxidized under prolonged friction between the electrode block 568 and the metal foil 563, which can easily lead to poor contact between the electrode block 568 and the metal foil 563. This can cause the dust removal mechanism 5 to malfunction and reduce the dust removal effect. Therefore, in this embodiment, the mounting block 567 is slidably installed inside the purification air duct 55, and an adjusting screw 566 is rotatably installed inside the purification air duct 55. The adjusting screw 566 is threadedly connected to the mounting block 567.

[0070] Specifically, when oxidation occurs at the metal foil 563 in contact with the electrode block 568, the adjusting screw 566 can be rotated. The adjusting screw 566 moves the mounting block 567 and the electrode block 568, allowing the electrode block 568 to be moved to other areas of the metal foil 563, thereby enabling the metal foil 563 to make good contact with the electrode block 568 again and avoiding unstable electrical connection.

[0071] The present invention provides an intelligent detection and early warning device for safe electricity use. Due to the presence of the adjusting screw 566, a gap appears between the top of the metal foil 563 and the partition 53. To allow the metal foil 563 to rotate carrying dust to the side of the striking component 58, a gap must also be left between the bottom of the metal foil 563 and the bottom of the purification duct 55. This causes air entering the purification duct 55 from the air inlet 2 to directly enter the space between the metal foil 563 and the partition 53 through the gap at the bottom of the metal foil 563, and then escape from the metal foil 563. The dust-laden air is discharged again through the gap at the top, causing it to pass over the area between the cathode plate 561 and the metal foil 563. This prevents the electrostatic dust removal assembly 56 from removing dust from this part of the air, resulting in a reduced dust removal effect. Therefore, in this embodiment, the dust removal mechanism 5 also includes a windbreak structure 510. The windbreak structure 510 includes a windbreak plate 5101 fixedly installed on the partition plate 53. A friction strip 5102 is fixedly installed at the bottom of the windbreak plate 5101, and the bottom of the friction strip 5102 is in contact with the surface of the metal foil 563.

[0072] Specifically, the friction strip 5102 is made of wear-resistant rubber.

[0073] The combination of the baffle plate 5101 and the friction strip 5102 will block the gap at the top of the metal foil 563, preventing air from entering the space between the metal foil 563 and the partition plate 53, so that all the air passes through the cathode plate 561 and the metal foil 563, improving the dust removal effect.

[0074] Furthermore, the friction strip 5102 will also rub the surface of the metal foil 563 against each other, thereby removing the oxide layer on the surface of the metal foil 563, making the contact between the metal foil 563 and the electrode block 568 better, and extending the service life of the metal foil 563.

[0075] Finally, the friction strip 5102 also intercepts dust on the surface of the metal foil 563, removes dust that the striking component 58 cannot knock off, improves the adhesion and utilization rate of dust on the surface of the metal foil 563, and improves the dust removal effect.

[0076] Working principle:

[0077] Start the cooling fan 9 and connect the power supply between the cathode plate 561 and the metal foil 563. The cooling fan 9 draws air from the box 3. Under negative pressure, outside air enters the purification air duct 55 from the air inlet 2. After the metal foil 563 removes dust from the air, the pure air passes through the baffle air duct 52 and the return air duct 54 in sequence, and enters the box 3 from the air outlet. Then the air is drawn out by the cooling fan 9. At the same time, the cold air carries away the heat of the control and early warning component 6 and is discharged from the box 3 from the heat dissipation hole 8.

[0078] At the same time, the air flowing through the return air duct 54 will drive the rotating column 582 to rotate, the rotating column 582 will drive the triangular push rod 5812 to rotate, the triangular push rod 5812 will drive the striking head 586 away from the surface of the metal foil 563, and when the triangular push rod 5812 passes the push ball 5811, under the action of gravity, the striking head 586 will quickly strike the surface of the metal foil 563. Under the action of vibration, the dust on the surface of the metal foil 563 will be knocked off, and the falling dust will pass through the first dust hole 592 and fall into the collection box 594.
