Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a frequency converter which is easy to install. Background Art

[0002] The frequency converter is an electric energy control device that converts the industrial frequency power supply into another frequency by using the on-off function of power semiconductor devices. However, the existing frequency converters have some shortcomings when used;

[0003] Existing inverters basically have a mounting structure on the back, which means that the inverter can only be installed in one direction, which limits the installation direction of the inverter and causes inconvenience. In addition, the mounting structures of existing inverters are relatively complex, which leads to a long installation time. In addition, the mounting structures are basically attached to the back of the inverter, which means that the inverter can only dissipate heat at the top, which can easily cause dust to fall from the heat dissipation holes into the inverter, thereby causing dust to damage the internal parts of the inverter. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a frequency converter that is easy to install, so as to more accurately solve the problems of inconvenient installation and easy entry of dust into the interior of the frequency converter.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model proposes an inverter that is easy to install, comprising an inverter body, connecting frames are fixedly arranged on both sides of the inverter body, a connecting rod is fixedly arranged on the back of the inverter body, mounting plates are fixedly arranged at both ends of the connecting rod, a threaded rod is threadedly connected to the front of the connecting frame, a threaded sleeve is threadedly connected to the surface of the threaded rod, a clamping plate is fixedly arranged on the surface of the threaded sleeve, a top cover is movably arranged on the top of the connecting frame, and a fan is fixedly arranged inside the top cover.

[0007] Furthermore, rectangular slide grooves are provided on both sides of the inverter body, and heat dissipation holes are provided on the top and back of the inverter body. The rectangular slide grooves are provided to facilitate the movement of the clamping plate. The heat dissipation holes can be used to easily diffuse the heat inside the inverter, thereby avoiding the situation where the inverter itself has a high temperature and damages its internal parts.

[0008] Furthermore, a turntable is fixedly provided on the front side of the threaded rod, and the turntable is located outside the inverter body. The surface of the turntable is provided with anti-slip grooves. The anti-slip grooves can increase the friction between the user's hand and the turntable, making it easier for the user to drive the threaded rod to rotate by turning the turntable.

[0009] Furthermore, the surface of the threaded rod is provided with two groups of symmetrically distributed threads, and a group of threaded sleeves are threadedly connected to the two groups of threads, ensuring that the threaded rod can drive the two groups of threaded sleeves to move toward or relative to each other when rotating.

[0010] Furthermore, one side of the clamping plate is arranged as an arc structure, and a rubber block is arranged on the surface of the arc structure, and the two adjacent groups of the clamping plates are symmetrically distributed. The arc structure can clamp devices of most shapes, thereby increasing the applicability of the device. The rubber block can increase the friction between the clamping plate and the clamped device, thereby avoiding the occurrence of unstable clamping.

[0011] Furthermore, the connecting rod is an overall C-shaped structure, and there are two groups of connecting rods, which are respectively located on both sides of the back of the inverter body. The connecting rods with the C-shaped structure can ensure that there is a gap between the inverter and the installation wall. The two groups of connecting rods can ensure that the force on the inverter is uniform, thereby ensuring the stability of the installation, and facilitating heat dissipation through the heat dissipation holes on the back of the inverter.

[0012] Furthermore, the top cover is a triangular structure as a whole, and a horizontal plate is fixedly arranged inside the top cover, and a motor is movably connected inside the horizontal plate. The triangular structure can utilize the inclined surface to drain the fallen dust, and the movable connection can ensure that the motor swings inside the horizontal plate.

[0013] Furthermore, the fan is fixedly connected to the output end of the motor, and the motor is used to drive the fan to rotate, thereby cooling the inverter body.

[0014] Beneficial effects of the utility model:

[0015] The utility model adds a clamping and fixing device on the side of the inverter body, and the clamping plate can clamp some devices through the rotation of the threaded rod, so that the inverter body can be installed in the air, and the inverter can be installed by the coordinated use of bolts and the mounting plate. The curved shape of the connecting rod can make the inverter away from the mounting surface, so that the inverter can be radiated from the back. Not only does it increase the installation method of the inverter body, but it is also convenient and quick to operate, and has strong practical significance.

[0016] The utility model can drain fallen impurities or dust by installing a triangular cover plate on the top of the inverter, preventing dust from entering the inverter through the heat dissipation holes on the top of the inverter, and driving the fan to blow through the motor, thereby not only dissipating the heat inside the inverter, but also driving the top cover to vibrate on the top of the inverter through the shaking of the motor and the fan, thereby shaking off the dust on the surface of the top cover.

[0025] As an implementation method in this embodiment, Figure 2As shown, a turntable is fixedly provided on the front of the threaded rod 4, and the turntable is located outside the inverter body 1, and an anti-skid groove is provided on the surface of the turntable. The anti-skid groove can increase the friction between the user's hand and the turntable, so that the user can drive the threaded rod 4 to rotate by turning the turntable; two groups of symmetrically distributed threads are provided on the surface of the threaded rod 4, and a group of threaded sleeves 5 are threadedly connected on the two groups of threads to ensure that the threaded rod 4 can drive the two groups of threaded sleeves 5 to move toward or relative to each other when rotating; one side of the clamping plate 6 is provided with an arc structure, and the surface of the arc structure is provided with rubber blocks, which are symmetrically distributed between two adjacent groups of clamping plates 6. The arc structure can clamp devices of most shapes and increase the applicability of the device. The rubber block can increase the friction between the clamping plate 6 and the clamped device to avoid unstable clamping.

[0026] As an implementation method in this embodiment, Figure 3 As shown, the connecting rod 2 is an overall C-shaped structure, and there are two groups of connecting rods 2, which are respectively located on both sides of the back of the inverter body 1. The connecting rod 2 with a C-shaped structure can ensure that there is a gap between the inverter and the installation wall. The two groups of connecting rods 2 can ensure that the force on the inverter is uniform, thereby ensuring the stability of the installation, and facilitating heat dissipation through the heat dissipation holes on the back of the inverter.

[0027] As an implementation method in this embodiment, Figure 4 As shown, the top cover 7 is a triangular structure as a whole, and a horizontal plate is fixedly arranged inside the top cover 7, and a motor is movably connected inside the horizontal plate. The triangular structure can use the inclined surface to drain the fallen dust, and the movable connection can ensure that the motor swings inside the horizontal plate; the fan 8 is fixedly connected to the output end of the motor, and the motor is used to drive the fan 8 to rotate, thereby cooling the inverter body 1.

[0028] Working principle: During installation, the mounting plate 3 can be directly placed on the mounting surface, and then the mounting plate 3 and the mounting wall can be connected by plugging the bolts, or the threaded rod 4 can be manually rotated, and the threaded sleeve 5 can be driven to move on the surface of the threaded rod 4 by the rotation of the threaded rod 4, and then the threaded sleeve 5 will drive the clamping plate 6 to move synchronously, and then the two groups of clamping plates 6 can be moved toward each other to clamp the device, thereby realizing the stable installation of the inverter body 1. The appropriate installation method of the inverter can be selected according to needs;

[0029] When the inverter is working, that is, the motor is turned on, and the motor is used to drive the fan 8 to rotate, and then the fan 8 is used to exchange the hot and cold air flows inside and outside the inverter body 1. When the fan 8 rotates, it will generate a reverse force on the motor, thereby driving the motor to shake on the horizontal plate inside the top cover 7, and then driving the top cover 7 to shake at the top of the connecting frame on both sides of the inverter body 1, thereby shaking the fallen dust to avoid dust accumulation.

[0030] It is worth mentioning that the mounting plate 3 is a commercially available product, which can be used in conjunction with the bolts to mount the device on the wall. Since the mounting plate 3 is a commercially available product, it will not be elaborated on in detail here.

[0031] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
