Description

Technical Field

[0001] This utility model relates to the field of inverter technology, specifically an inverter with moisture-proof function. Background Technology

[0002] An inverter is a power conversion device that converts direct current (DC) to alternating current (AC). It is commonly used in solar power systems, wind power systems, and other applications requiring DC-to-AC conversion. Inverters convert DC power generated by solar panels or wind turbines into AC power for domestic, industrial, or commercial use. The main function of an inverter is to transform the voltage, current, and power characteristics of a DC power source into those of an AC power source to suit various load requirements.

[0003] When an inverter is placed or used, humid air can enter the inverter from its surface, reducing the lifespan of the internal electrical components and making it unusable for extended periods. This significantly shortens the inverter's lifespan and causes unnecessary economic losses for the user. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of existing inverters, where external moisture can enter the inverter during use and affect its service life.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an inverter with a moisture-proof function, comprising an inverter body, a connection panel mounted on the surface of the inverter body, heat sinks fixedly connected to both sides of the inverter body, a moisture-proof device provided on the surface of the inverter body, a weight-increasing device fixedly connected to the upper surface of the inverter body, several rectangular strips formed on the upper surface of the inverter body, the moisture-proof device comprising four extension rods, the four extension rods being paired up, two extension rods being fixedly connected to the surface of the heat sink, a sliding rod slidably connected to the end of the two extension rods away from the heat sink, a placement frame fixedly connected to the end of the sliding rod away from the extension rod, a square frame fixedly connected to the inner wall of the placement frame, an activated carbon plate slidably connected to the inner wall of the square frame, and several air guide holes formed on both sides of the placement frame.

[0008] Furthermore, a circular plate is fixedly connected to the surface of each of the four extension rods, and a spring is fitted onto the surface of the slide rod. The two ends of the spring are fixedly connected to the circular plate and the surface of the placement frame, respectively.

[0009] Furthermore, a folding sleeve is fixedly connected to the surface of the circular plate, and the folding sleeve wraps around the surface of the spring.

[0010] Furthermore, an air guide frame is fixedly connected to the surface of the heat sink, and a plurality of exhaust holes are provided on the lower surface of the air guide frame, the lower surface of the air guide frame being inclined.

[0011] Furthermore, the weight-adding device includes two connecting strips, both of which are fixedly connected to the upper surface of the inverter body. Two connecting rods are slidably connected to the surfaces of the two connecting strips. A round rod is rotatably connected to the end of each connecting rod away from the connecting strip. A pull rod is fixedly connected to the end of the round rod away from the connecting strip. The size of the pull rod is adapted to the size of the rectangular strip. A placement cloth is fixedly connected to the surfaces of the two connecting strips. The side of the placement cloth away from the connecting strip is fixedly connected to the pull rod.

[0012] Furthermore, the surface of the cloth to be placed has a plurality of anti-slip holes, and the plurality of anti-slip holes are linearly arrayed on the surface of the cloth to be placed.

[0013] Furthermore, a support rod is movably connected to the inner wall of the pull rod, and two anti-slip pads are glued to the surface of the support rod, both of which are made of rubber.

[0014] Compared with existing technologies, this inverter with moisture-proof function has the following advantages:

[0015] I. This utility model, through the setting of a moisture-proof device, can install an activated carbon plate with a moisture-absorbing effect inside the placement frame. When the inverter body is placed, the moisture is absorbed by the activated carbon plate and will not enter the inner wall of the inverter body and affect the electrical components. Furthermore, the placement frame can be unfolded through the extension rod and sliding rod. The activated carbon plate is easy to install, can be quickly replaced, and can be used continuously.

[0016] Second, this utility model, through the weight-increasing device, allows the inverter to be used outdoors. By unfolding the cloth, the user can place heavy objects on the surface of the cloth to increase the weight of the inverter body. This makes the inverter body less likely to move due to collisions or other situations when the user is using it, and thus prevents it from coming into contact with other objects and causing collision damage.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: an inverter with a moisture-proof function, including an inverter body 1, a connection panel 2 installed on the surface of the inverter body 1, heat dissipation plates 3 fixedly connected to both sides of the inverter body 1, a moisture-proof device 4 provided on the surface of the inverter body 1, a weight-increasing device 5 fixedly connected to the upper surface of the inverter body 1, and a plurality of rectangular strips 6 opened on the upper surface of the inverter body 1.

[0026] In this embodiment of the utility model: when the inverter body 1 is in use, the moisture-proof device 4 can absorb the moisture around the inverter body 1, so that the moisture will not enter the interior of the inverter body 1. Furthermore, the weight-increasing device 5 can adjust the weight of the inverter body 1, making the inverter body 1 less prone to movement and thus less prone to damage, thereby protecting the inverter body 1 to a certain extent.

[0027] like Figure 1-4 As shown, the moisture-proof device 4 includes four extension rods 402, which are arranged in pairs. Two extension rods 402 are fixedly connected to the surface of the heat sink 3. The ends of the two extension rods 402 away from the heat sink 3 are slidably connected to a slide rod 403. The ends of the slide rods 403 away from the extension rods 402 are fixedly connected to a placement frame 407. A square frame 409 is fixedly connected to the inner wall of the placement frame 407. An activated carbon plate 410 is slidably connected to the inner wall of the square frame 409. Several air guide holes 408 are provided on both sides of the placement frame 407.

[0028] When the placement frame 407 is unfolded, the activated carbon plate 410 can be slidably installed inside the square frame 409. At this time, moisture enters the interior of the placement frame 407 through the air guide hole 408. The moisture is adsorbed on the surface of the activated carbon plate 410 and will not enter the interior of the inverter body 1.

[0029] The surfaces of the four extension rods 402 are all fixedly connected to circular plates 404, and the surfaces of the slide rods 403 are fitted with springs 405. The two ends of the springs 405 are fixedly connected to the surfaces of the circular plates 404 and the placement frame 407, respectively.

[0030] The spring 405 can tighten the placement frame 407 when carrying the inverter body 1, so that the placement frame 407 will not unfold and shake when the user carries it, which facilitates the carrying and use of the moisture-proof device 4 installed on the surface of the inverter body 1.

[0031] A folding sleeve 406 is fixedly connected to the surface of the circular plate 404, and the folding sleeve 406 wraps around the surface of the spring 405.

[0032] When the inverter body 1 is used outdoors, it may rain. At this time, the folding sleeve 406 can prevent water droplets from falling on the surface of the spring 405, making the spring 405 less susceptible to corrosion and damage, and protecting the service life of the spring 405 to a certain extent.

[0033] A venting frame 411 is fixedly connected to the surface of the heat sink 3. Several exhaust holes 401 are opened on the lower surface of the venting frame 411, and the lower surface of the venting frame 411 is inclined.

[0034] The hot air emitted by the heat sink 3 is guided by the air guide frame 411 to the lower surface of the inverter body 1 and sprayed onto the surface of the activated carbon plate 410, which can dry the activated carbon plate 410, increase the service life of the activated carbon plate 410, and enable it to be used for moisture protection for a long time.

[0035] Working Principle: When using or placing the inverter, the user can increase the distance between the placement frame 407 and the inverter body 1. At this time, the slide bar 403 slides from inside the extension bar 402, allowing the user to place the new activated carbon plate 410 on the inner wall of the square frame 409, thus completing the installation of the activated carbon plate 410. The user then releases the pulling force between the inverter body 1 and the placement frame 407, causing the lower surface of the inverter body 1 to adhere to the surface of the placement frame 407. The spring 405 tightens the distance between the placement frame 407 and the inverter body 1, facilitating the movement of the inverter body. When the inverter body 1 starts working, the internal heat will dissipate outward through the heat sink 3. Then, the heat will be guided by the air guide frame 411 to move towards the lower surface of the inverter body 1. Furthermore, because the lower surface of the air guide frame 411 is inclined and has an exhaust hole 401, the heat can be sprayed onto the surface of the activated carbon plate 410. At this time, the heat accumulates inside the placement frame 407, which can dry the activated carbon plate 410. The heat can still be dissipated from the openings on both sides of the placement frame 407, without affecting the heat dissipation of the inverter body 1.

[0036] like Figure 1-5 As shown, the weight-adding device 5 includes two connecting bars 51, both of which are fixedly connected to the upper surface of the inverter body 1. Two connecting rods 57 are slidably connected to the surfaces of the two connecting bars 51. A round rod 58 is rotatably connected to the end of each connecting rod 57 away from the connecting bar 51. A pull rod 53 is fixedly connected to the end of the round rod 58 away from the connecting bar 51. The size of the pull rod 53 is adapted to the size of the rectangular bar 6. A placement cloth 52 is fixedly connected to the surfaces of the two connecting bars 51. The side of the placement cloth 52 away from the connecting bar 51 is fixedly connected to the pull rod 53.

[0037] By unfolding the cover, heavy outdoor objects can be placed on the surface of the cover, further increasing the weight of the inverter body 1. This makes it less likely for the inverter body 1 to shift, thus facilitating its outdoor use.

[0038] The surface of the cloth 52 is provided with a number of anti-slip holes 55, and the number of anti-slip holes 55 are linearly arrayed on the surface of the cloth 52.

[0039] The anti-slip holes 55 can increase the friction between the object and the weight, improve the stability of the weight, and thus facilitate the use of the weight-adding device 5.

[0040] A support rod 54 is movably connected to the inner wall of the pull rod 53. Two anti-slip pads 56 are glued to the surface of the support rod 54. Both anti-slip pads 56 are made of rubber.

[0041] The support rod 54, together with the anti-slip mat 56, can be supported on the ground. At this time, it can help the cover cloth unfold, so that the surface of the cover cloth can place heavy objects of various shapes, which increases the practicality of the weight-adding device 5.

[0042] Working principle: When the user pulls the lever 53 outward, the cover cloth can be unfolded, and the support rod 54 can be rotated out from the inner wall of the lever 53. With the rotation position between the connecting rod 57 and the round rod 58, the support rod 54 can be supported on the ground. At the same time, the anti-slip pad 56 abuts against the ground to increase the stability of the support rod 54 and prevent it from changing position. At this time, the user can place heavy objects found outdoors on the surface of the cover cloth. Due to the support of the support rod 54, round, square or some irregularly shaped heavy objects placed on the surface of the cover cloth are not easy to fall off. At the same time, the anti-slip holes 55 further increase the friction between the heavy objects and the heavy objects, further improving the stability of the placement. By adding heavy objects, the inverter body 1 will not change position after being placed outdoors, and thus will not collide with other objects and be damaged.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
