Description

Technical Field

[0001] The invention relates to a frequency converter, in particular to an outdoor waterproof frequency converter applied in the technical field of frequency converters. Background Art

[0002] With the development of industrial automation and power electronics technology, inverters have been widely used in various fields. In outdoor environments, such as open-air mining equipment, irrigation systems, outdoor industrial production lines, etc., ordinary inverters are easily affected by environmental factors such as rain, dew, dust and moisture. These factors may cause problems such as short circuits in the inverter's internal circuits, corrosion of components, and degradation of insulation performance, which will seriously affect the normal operation and service life of the inverter.

[0003] A Chinese patent with publication number CN219643806U discloses a waterproof inverter. When waterproofing the inverter, the inverter body is installed inside the mounting frame, and the upper and lower ends of the inverter body do not contact the upper and lower side walls of the mounting frame. Even if there is water on the lower side wall of the mounting frame, it will not touch the inverter body. At the same time, when installing the connecting line, the cooperation between the first sealing pad, the second sealing and the drying hole can make the inside of the mounting groove in a dry state.

[0004] A Chinese patent with publication number CN221381476U discloses a waterproof inverter, which solves the problem that traditional inverters are generally used by directly exposing the inverter to the outside. Under special circumstances, water will enter the inverter, causing damage to the inverter, making the device difficult to use, reducing the efficiency of the device, and making it difficult for the device to work effectively when in use.

[0005] In the prior art, in order to prevent the inverter from being damaged by rain and other factors, the inverter is mostly protected by a sealing structure. Although the sealing structure can improve the waterproof performance of the inverter, it will also reduce the heat dissipation performance of the inverter. Since the inverter generates a certain amount of heat when it is running, when the inverter temperature is high, if the heat cannot be dissipated in time, the inverter will be in a high temperature state for a long time and damaged. Therefore, we propose an outdoor waterproof inverter. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to balance the waterproof performance and the heat dissipation performance of the inverter.

[0007] In order to solve the above problems, the present invention provides an outdoor waterproof inverter, including an inverter body and a waterproof protection mechanism, the waterproof protection mechanism includes a sealed waterproof box, the inverter body is installed in the sealed waterproof box, the outer walls on both sides of the sealed waterproof box are provided with heat dissipation holes, and a dustproof net matching with the heat dissipation holes is fixedly installed in the heat dissipation holes;

[0008] The waterproof intelligent protection mechanism also includes an intelligent adjustment sealing component and an intelligent protection controller. The intelligent adjustment sealing component includes a vertical electric telescopic rod fixedly installed on the top of the sealed waterproof box, and the output end of the vertical electric telescopic rod is fixedly connected with a U-shaped linkage frame. The intelligent adjustment sealing component also includes two sealing covers matching the heat dissipation holes. The two sealing covers are respectively covered on the outsides of the two heat dissipation holes, and the sealing covers are slidingly sealed with the outer wall of the sealed waterproof box. A horizontal electric telescopic rod is fixedly installed in the sealing cover, and a dust removal brush matching the dustproof net is fixedly connected to the output end of the horizontal electric telescopic rod.

[0010] In the above-mentioned outdoor waterproof inverter, the waterproof intelligent protection mechanism can not only provide a sealed protection for the inverter body to prevent the inverter body from being eroded by rain and the like, but also when the temperature of the inverter body is high, the waterproof intelligent protection mechanism will automatically perform intelligent adjustments to ventilate and dissipate heat, so that the inverter in this application can take into account both waterproof performance and heat dissipation performance, and can operate safely and stably in outdoor environments.

[0011] As a further improvement of the present application, one end of the dustproof net is flush with the outer wall of the sealed waterproof box, the dust removal brush is against the outer wall of the sealed waterproof box, the connecting spring is in a compressed state, and the opening temperature threshold and the sealing temperature threshold are reasonably set through the threshold setting module according to the normal working temperature range of the inverter body. The temperature sensor is used to monitor the temperature inside the sealed waterproof box, and the temperature data monitored by the temperature sensor will be transmitted to the adjustment control module in real time. When the temperature inside the sealed waterproof box rises to the opening temperature threshold, the adjustment control module controls the horizontal electric telescopic rod to extend, causing the sealing cover to move away from the sealed waterproof box, and then, the adjustment control module controls the vertical electric telescopic rod to drive the sealing cover to move downward until the sealing cover moves to the bottom of the heat dissipation hole, causing the heat dissipation hole to be turned on, so as to ventilate and dissipate heat inside the sealed waterproof box, and the dust removal brush cleans the dust on the dustproof net. When the temperature inside the sealed waterproof box drops to the sealing temperature threshold, the adjustment control module controls the vertical electric telescopic rod to drive the observation plate to move upward and reset, and then, the adjustment control module controls the horizontal electric telescopic rod to retract, causing the sealing cover to be completely reset.

[0012] As a further improvement of the present application, a cooling fan is fixedly installed in the sealed waterproof box, and a fan control module is also provided in the intelligent protection controller. The adjustment control module is signal-connected to the fan control module, and the fan control module is signal-connected to the cooling fan, which can further improve the heat dissipation performance of the inverter.

[0013] As a further improvement of the present application, a connecting slide rod is fixedly connected to the outer wall of the sealing hole cover, and the connecting slide rod passes through the linkage frame and is slidably connected thereto. The connecting slide rod can improve the stability of the sealing hole cover during movement, and further improve the reliability of the waterproof protection mechanism. A rain shield fixedly installed on the outer wall of the sealed waterproof box is provided above the sealing hole cover. When the heat dissipation hole is in a conducting state, the rain shield can prevent rainwater and the like from entering the sealed waterproof box through the heat dissipation hole.

[0014] As a further improvement of the present application, the sealed waterproof box is provided with a box door which is movably and sealingly connected thereto, and the box door is provided with a door lock, so that relevant technical personnel can conveniently operate and maintain the inverter body.

When the temperature of the inverter body is high, the waterproof intelligent protection mechanism will also use the air pressure changes caused by the temperature to detect the sealing of the sealed waterproof box.

[0018] As another improvement supplement to the present application, the combined leak detection assembly also includes a drain pipe connected to the bottom end of the sealed waterproof box, and a solenoid valve is provided on the drain pipe.

[0019] In summary, the present application sets up a waterproof intelligent protection mechanism, so that the waterproof intelligent protection mechanism can not only provide a sealed protection for the inverter body to prevent the inverter body from being eroded by rain and the like, but also greatly improve the waterproof performance of the inverter.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-Figure 5An outdoor waterproof inverter is shown, including an inverter body 001 and a waterproof intelligent protection mechanism, the waterproof intelligent protection mechanism includes a sealed waterproof box 201, the inverter body 001 is installed in the sealed waterproof box 201, and the outer walls on the left and right sides of the sealed waterproof box 201 are provided with heat dissipation holes 204, and the heat dissipation holes 204 are fixedly installed with dustproof nets 205 matching therewith, the waterproof intelligent protection mechanism also includes an intelligent adjustment sealing hole component and an intelligent protection controller 004, the intelligent adjustment sealing hole component includes a vertical electric telescopic rod 301 fixedly installed on the top of the sealed waterproof box 201, the output end of the vertical electric telescopic rod 301 is fixedly connected with a U-shaped linkage frame 302, the intelligent adjustment sealing hole component also includes two sealing hole covers 303 matching the heat dissipation holes 204, the two sealing hole covers 303 are respectively covered on the outsides of the two heat dissipation holes 204, and the sealing hole covers 303 are connected to the sealed waterproof The outer wall of the water tank 201 is slidably sealed and connected, a horizontal electric telescopic rod 304 is fixedly installed in the sealing cover 303, and a dust removal brush 305 matching the dustproof net 205 is fixedly connected to the output end of the horizontal electric telescopic rod 304, and a connecting spring 306 is fixedly connected between the sealing cover 303 and the linkage frame 302. The intelligent sealing component also includes a temperature sensor 307 installed in the sealed waterproof box 201, and a threshold setting module and an adjustment control module are provided in the intelligent protection controller 004. The temperature sensor 307 and the threshold setting module are both connected to the adjustment control module signal, and the adjustment control module is connected to the vertical electric telescopic rod 301 and the horizontal electric telescopic rod 304 signal. One end of the dustproof net 205 is flush with the outer wall of the sealed waterproof box 201, the dust removal brush 305 is against the outer wall of the sealed waterproof box 201, and the connecting spring 306 is in a compressed state.

[0033] Under normal circumstances (that is, when the temperature of the inverter body 001 is normal), the sealed waterproof box 201 is in a sealed state, and the inverter body 001 is located in the sealed waterproof box 201, so that the waterproof protection mechanism can provide a sealed protection for the inverter body 001, so that the inverter is protected from the intrusion of rainwater, etc., thereby greatly improving the waterproof performance of the inverter, and because the connecting spring 306 is in a compressed state, the connecting spring 306 can provide an elastic force, under the action of the elastic force, the sealing hole cover 303 can be tightly attached to the outer wall of the sealed waterproof box 201, thereby improving the sealing of the connection between the sealing hole cover 303 and the sealed waterproof box 201, and further preventing rainwater, etc. from entering the sealed waterproof box 201 through the heat dissipation hole 204. According to the normal operation of the inverter body 001 The threshold setting module is used to reasonably set the opening temperature threshold and the sealing temperature threshold in the operating temperature range. The temperature sensor 307 is used to monitor the temperature in the sealed waterproof box 201, and the temperature data monitored by the temperature sensor 307 will be transmitted to the adjustment control module in real time. When the temperature in the sealed waterproof box 201 rises to the opening temperature threshold (that is, when the temperature of the inverter body 001 is high), the adjustment control module controls the horizontal electric telescopic rod 304 to extend, so that the sealing cover 303 is away from the sealed waterproof box 201 (the extension of the horizontal electric telescopic rod 304 will push the dust removal brush 305. Since the dust removal brush 305 is against the outer wall of the sealed waterproof box 201, the dust removal brush 305 cannot be pushed, so the extension of the horizontal electric telescopic rod 304 will drive the sealing cover 303 to move away from the sealed waterproof box 201. The sealing and waterproof box 201 moves in the direction of the sealing and waterproof box 201), and then, the adjustment control module controls the vertical electric telescopic rod 301 to drive the sealing hole cover 303 to move downward, until the sealing hole cover 303 moves to the bottom of the heat dissipation hole 204, so that the heat dissipation hole 204 is turned on, so as to ventilate and dissipate heat inside the sealing and waterproof box 201, and make the dust removal brush 305 clean the dust on the dustproof net 205 (in the process of the observation plate 203 moving downward, the horizontal electric telescopic rod 304 and the dust removal brush 305 will also move together. When the dust removal brush 305 moves past the dustproof net 205, the dust on the dustproof net 205 can be wiped off, thereby achieving the purpose of automatically cleaning the dust on the dustproof net 205). Before the sealing hole cover 303 starts to move, the horizontal electric telescopic rod 304 and the dust removal brush 30 5, the sealing cover 303 will be away from the sealed waterproof box 201, so that during the movement of the sealing cover 303, the sealing cover 303 will not rub against the sealed waterproof box 201, thereby preventing the sealing cover 303 from being worn, and further improving the reliability of the waterproof protection mechanism. With the progress of ventilation and heat dissipation, the temperature in the sealed waterproof box 201 will gradually decrease. When the temperature in the sealed waterproof box 201 drops to the sealing temperature threshold (that is, after the temperature of the inverter body 201 returns to normal), the adjustment control module controls the vertical electric telescopic rod 301 to drive the observation plate 203 to move upward and reset, and then the adjustment control module controls the horizontal electric telescopic rod 304 to retract, so that the sealing cover 303 is completely reset, so that the heat dissipation hole 204 is sealed again.Then the sealed waterproof box 201 is restored to a sealed state. Therefore, through the setting of the waterproof intelligent protection mechanism, the waterproof intelligent protection mechanism can not only provide a sealed protection for the inverter body 001 to prevent the inverter body 001 from being eroded by rain and the like, but also greatly improve the waterproof performance of the inverter. When the temperature of the inverter body 001 is high, the waterproof intelligent protection mechanism will automatically make intelligent adjustments to ventilate and dissipate heat. In the adjustment process, it can not only effectively avoid the wear of the sealing hole cover 303, but also automatically clean the dust on the dustproof net 205, thereby not only improving the reliability of the waterproof intelligent protection mechanism, but also further improving the waterproof performance and heat dissipation performance of the inverter, so that the inverter in this application can take into account both waterproof performance and heat dissipation performance, and can operate safely and stably in outdoor environments.

[0034] See also Figure 2 and Figure 5 A cooling fan 206 is fixedly installed in the sealed waterproof box 201, and a fan control module is also provided in the intelligent protection controller 004. The regulating control module is connected to the fan control module by signal, and the fan control module is connected to the cooling fan 206 by signal. When the temperature in the sealed waterproof box 201 rises to the opening temperature threshold, the regulating control module will also send a start signal to the fan control module, causing the fan control module to start the cooling fan 206, and when the temperature in the sealed waterproof box 201 drops to the sealing temperature threshold, the regulating control module will send a shutdown signal to the fan control module, causing the fan control module to shut down the cooling fan 206, thereby further improving the heat dissipation performance of the inverter.

[0035] See also Figure 1-Figure 3 A connecting slide bar 308 is fixedly connected to the outer wall of the sealing hole cover 303, and the connecting slide bar 308 penetrates the linkage frame 302 and is slidably connected thereto. The connecting slide bar 308 can improve the stability of the sealing hole cover 303 when it moves, and further improve the reliability of the waterproof protection mechanism. A rain shield 309 fixedly installed on the outer wall of the sealed waterproof box 201 is arranged above the sealing hole cover 303. When the heat dissipation hole 204 is in a conducting state, the rain shield 309 can prevent rainwater from entering the sealed waterproof box 201 through the heat dissipation hole 204, and the sealed The sealed waterproof box 201 is provided with a box door 202 that is movably and sealingly connected thereto, and the box door 202 is provided with a door lock, so that relevant technical personnel can easily operate and maintain the inverter body 001. An observation panel 203 is embedded through the box door 202, and the observation panel 203 is made of transparent material, so that relevant technical personnel can observe the situation inside the sealed waterproof box 201 through the observation panel 203. A plurality of heat sinks are embedded through the back of the sealed waterproof box 201, which can further improve the heat dissipation performance of the inverter.

[0036] The second implementation method:

[0037] See also Figure 6-Figure 8Different from the first embodiment, the waterproof intelligent protection mechanism also includes a joint leak detection component, which includes a connecting pipe 501 connected to the bottom end of the sealed waterproof box 201, and the bottom end of the connecting pipe 501 is connected to a sealed leak detection cylinder 502. A distance sensor 503 is fixedly installed on the inner wall of the bottom end of the sealed leak detection cylinder 502. A piston plate 504 is provided above the distance sensor 503 and is slidingly and sealingly connected to the sealed leak detection cylinder 502. A pair of elastic pull ropes 505 are fixedly connected between the piston plate 504 and the top inner wall of the sealed leak detection cylinder 502. A leakage judgment module and a remote alarm module are also provided in the intelligent protection controller 004. The distance sensor 503 is signal-connected to the leakage judgment module, and the leakage judgment module is signal-connected to the remote alarm module. The adjustment control module and the threshold setting module are both signal-connected to the leakage judgment module.

[0038] A distance threshold is reasonably set through the threshold setting module (the distance threshold is set based on the distance between the piston plate 504 and the distance sensor 503 when the sealed waterproof box 201 is in a sealed state and the temperature inside the sealed waterproof box 201 reaches the opening temperature threshold). When the sealed waterproof box 201 is in a sealed state, as the temperature inside the sealed waterproof box 201 increases, the air pressure inside the sealed waterproof box 201 will gradually increase. Under the connection effect of the connecting pipe 501, the air pressure above the piston plate 504 will also increase, causing the piston plate 504 to be pushed downward. The distance sensor 503 can monitor the distance between it and the piston plate 504, and the distance sensor 503 monitors The distance data obtained will be transmitted to the leakage judgment module in real time. When the temperature in the sealed waterproof box 201 rises to the opening temperature threshold, the adjustment control module will first send a leakage judgment signal to the leakage judgment module before controlling the vertical electric telescopic rod 301, the horizontal electric telescopic rod 304, etc. to adjust, so that the leakage judgment module can judge whether there is a problem with the sealing of the sealed waterproof box 201 by comparing the actual distance between the piston plate 504 and the distance sensor 503 with the distance threshold. If the actual distance between the piston plate 504 and the distance sensor 503 is not greater than the distance threshold, it means that there is no problem with the sealing of the sealed waterproof box 201. On the contrary, if the sealing of the sealed waterproof box 201 is If there is a problem with the sealing performance of the sealed waterproof box 201, the air in the sealed waterproof box 201 will leak out, causing the piston plate 504 to be unable to move downward under the action of air pressure, or only move downward a very small distance. At this time, the actual distance between the piston plate 504 and the distance sensor 503 will be greater than the distance threshold, so that the leakage judgment module can judge whether there is a problem with the sealing performance of the sealed waterproof box 201 by analyzing the distance data monitored by the distance sensor 503. After the judgment is completed, the leakage judgment module will send a feedback signal to the adjustment control module, and then the adjustment control module will control the horizontal electric telescopic rod 304, the vertical electric telescopic rod 301, etc. to adjust, and when the judgment result is that the sealing performance of the sealed waterproof box 201 is When there is a problem with the sealing performance of the sealed waterproof box 201, the leakage judgment module will also control the remote alarm module to send an alarm message to the relevant technical personnel. Therefore, through the setting of the combined leak detection component, the waterproof intelligent protection mechanism also has a self-inspection function. When the temperature of the inverter body 001 is high, the waterproof intelligent protection mechanism will also use the air pressure changes caused by the temperature to detect the sealing performance of the sealed waterproof box 201, and when the detection finds that there is a problem with the sealing performance of the sealed waterproof box 201, it will promptly warn the relevant technical personnel, prompting the relevant technical personnel to promptly perform corresponding maintenance on the sealed waterproof box 201, thereby further improving the reliability of the waterproof intelligent protection mechanism and further improving the waterproof performance and safety performance of the inverter.

[0039] See also Figure 7-Figure 8A permeable net 506 is fixedly installed above the piston plate 504, and an expansion leak detection filler 507 is filled between the permeable net 506 and the piston plate 504. The expansion leak detection filler 507 is made of water-absorbing and expanding material. The elastic drawstring 505 penetrates the permeable net 506 and is movably connected to it. When there is a problem with the sealing performance of the sealed waterproof box 201, resulting in water infiltration into the sealed waterproof box 201, the water in the sealed waterproof box 201 will flow into the sealed leak detection cylinder 502 through the connecting pipe 501. The piston plate 504 is pushed downward by the expansion leak detection filler 507, and the distance between the piston plate 504 and the distance sensor 503 is reduced to less than the distance threshold. When the leakage judgment module finds that the distance between the piston plate 504 and the distance sensor 503 is reduced to less than the distance threshold, the leakage judgment module will analyze it. If a leakage detection signal is received from the regulating and controlling module, it indicates that the downward movement of the piston plate 504 is caused by changes in temperature and air pressure, which is normal. On the contrary, if no leakage detection signal is received from the regulating and controlling module, it indicates that the downward movement of the piston plate 504 is not caused by changes in temperature and air pressure, but is caused by the swelling leakage detection filler 507 absorbing water and expanding, which further indicates that there is a problem with the sealing of the sealed waterproof box 201 and water has penetrated into the sealed waterproof box 201. At this time, the leakage judgment module will control the remote alarm module to send an alarm message to the relevant technical personnel. Therefore, through the joint setting of the anti-penetration net 506, the swelling leakage detection filler 507, etc., when there is a problem with the sealing of the sealed waterproof box 201 and water has penetrated into the sealed waterproof box 201, the leakage judgment module will detect and analyze this phenomenon, and promptly warn the relevant technical personnel, which can further improve the reliability of the waterproof intelligent protection mechanism and the safety of the inverter.

[0040] See also Figure 6 and Figure 8 The combined leak detection assembly also includes a drain pipe 508 connected to the bottom end of the sealed waterproof box 201. A solenoid valve 509 is provided on the drain pipe 508. The leakage judgment module is connected to the solenoid valve 509 signal. When the leakage judgment module finds that water has seeped into the sealed waterproof box 201, the leakage judgment module will also open the solenoid valve 509 to discharge the water in the sealed waterproof box 201 through the drain pipe 508 to prevent the inverter body 001 from being damaged due to water accumulation in the sealed waterproof box 201.

[0041] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
