A waterproof rotary rectifier assembly device

Abstract

This utility model provides a waterproof rotary rectifier component device, relating to the field of power electronic equipment. It includes an external tube with a cap at one end and an internal mounting plate inside. A rectifier is mounted and connected to the internal mounting plate. Multiple alignment ears are symmetrically arranged at the opening of the external tube. This utility model ensures initial sealing between the sealing ring and the inner wall of the cap by embedding an annular sealing ring into the annular groove of the internal ring. After direct installation, the sealing ring's own elasticity provides effective protection against dust and water droplets. Rotating the turntable drives the adjusting shaft to rotate, causing the slide rod and piston to move. Gas accumulated in the external air tube is discharged through the connecting pipe and gas channel, pressurizing the annular cavity inside the annular sealing ring. Under pressure, this allows the sealing ring to fit more tightly against the inner wall of the cap, enhancing the sealing effect.

Description

Technical Field

[0001] This utility model relates to the field of power electronic equipment, and in particular to a waterproof rotary rectifier component device. Background Technology

[0002] In the field of power electronics equipment, rectifiers, as key components for converting alternating current (AC) to direct current (DC), are widely used in industrial motors, new energy power generation systems, and underwater equipment. For rectifiers operating in humid environments, their waterproof sealing performance directly affects the reliability and service life of the equipment.

[0003] A search revealed a waterproof rotary rectifier assembly with publication number CN213425968U. This assembly includes a rotary rectifier, a rectifier mounting plate, a protective cover, and a wire-binding bracket. The wire-binding bracket is mounted on the rectifier mounting plate, which is divided into an upper and lower section. The lower section is circular, while the upper section consists of two crescent-shaped mounting plates symmetrically arranged on the lower section. The rotary rectifier is positioned between the two upper sections of the rectifier mounting plate. The protective cover is bolted to the rectifier mounting plate. The protective cover and the lower section of the rectifier mounting plate form a sealed space, which is waterproofed by injecting adhesive into the sealed space. This invention can be installed on any rotating component such as a shaft or fan, depending on the internal structural characteristics of the generator. It features a simple structure, convenient installation, and strong practicality.

[0004] One method involves potting, which involves injecting epoxy resin or silicone sealant into the sealing area to achieve waterproofing by filling the gaps. However, this sealing method makes later maintenance difficult. After potting, the component becomes a whole, and repairing or replacing the component requires damaging the sealing layer, resulting in high maintenance costs and time. Furthermore, the potting process may also cause the material to expand and contract due to changes in humidity and temperature in the environment, making it difficult to guarantee the sealing effect and prone to cracking after long-term use.

[0005] Therefore, it is necessary to provide a new waterproof rotary rectifier assembly to solve the above-mentioned technical problems. Utility Model Content

[0008] Preferably, the outer wall of the built-in ring is provided with an annular inner groove, and the annular sealing ring is fixedly installed in the annular inner groove.

[0009] Preferably, each of the plurality of fixing ears is provided with an installation port, and each of the plurality of installation ports is connected to a locking bolt. Each of the plurality of aligning ears is provided with a threaded port, and the plurality of locking bolts are respectively threadedly connected to the plurality of aligning ears.

[0010] Preferably, the inner wall of the external tube is provided with a gas flow channel, one end of the external tube is provided with a connecting tube, the other end of the connecting tube is connected to the gas flow channel, and the other end of the gas flow channel is connected to the annular cavity inside the annular sealing ring.

[0011] Preferably, the control component includes a strip plate, which is fixedly connected to the outer wall of the external tube. The external air tube is fixedly connected to the strip plate. A slide rod is slidably connected to one end of the external air tube. A piston is fixedly connected to one end of the slide rod, which is located inside the external air tube.

[0013] Compared with related technologies, the waterproof rotary rectifier component device provided by this utility model has the following advantages:

[0014] 1. This utility model provides a stable basic structure for sealing by embedding the annular sealing ring in the annular groove of the inner ring. This embedded design can accurately position the sealing ring and prevent it from shifting or twisting during the installation or use of the device. It ensures the initial sealing performance of the sealing ring in contact with the inner wall of the cover. After direct installation, it can also form effective protection by relying on the elasticity of the sealing ring itself, blocking the intrusion of dust, water droplets, etc., and laying a reliable foundation for subsequent pressure strengthening of sealing.

[0015] 2. This utility model drives the adjustment shaft to rotate by rotating the turntable, causing the pull plate to slide linearly along the fixed rod, which in turn moves the slide rod and piston. This allows the gas accumulated in the external air pipe to be discharged through the connecting pipe and the gas flow channel, pressurizing the annular cavity inside the annular sealing ring. Under the action of air pressure, the annular cavity can fit more tightly against the inner wall of the cover, enhancing the sealing effect. This effectively increases the contact pressure of the sealing surface, significantly improves the waterproof capability, and helps to cope with harsh environments such as high humidity and immersion, thus extending the service life and operational stability of the rectifier.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 3A waterproof rotary rectifier component device includes: an external tube 1, one end of which is provided with a cap 11; an internal mounting plate 2 is provided inside the external tube 1; a rectifier 3 is mounted and connected on the internal mounting plate 2; multiple alignment ears 4 are symmetrically provided at the opening of the external tube 1; multiple fixing ears 41 are symmetrically provided on the side wall of the cap 11; and a high-efficiency sealing mechanism, including an internal ring 5, which is fixedly connected to the opening of the external tube 1; an annular sealing ring 51 is provided on the outer side wall of the internal ring 5; an annular cavity is provided inside the annular sealing ring 51; an external air pipe 52 is provided outside the external tube 1; and a control component is provided between the external air pipe 52 and the external tube 1.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the outer wall of the built-in ring 5 is provided with an annular inner groove, and the annular sealing ring 51 is fixedly installed in the annular inner groove.

[0023] It should be noted that: the inner wall of the cover 11 fits the outer wall of the built-in ring 5, so that the annular sealing ring 51 in the annular groove is tightly fitted with the inner wall of the cover 11 and forms an initial seal by contacting the inner wall of the cover 11. At this time, there is no additional pressure in the annular cavity, and the sealing effect depends on the elasticity of the sealing ring itself.

[0024] When pressure is applied to the annular cavity, the annular sealing ring 51 can further fit tightly against the inner wall of the cover 11, forming a highly efficient seal.

[0025] refer to Figure 1 As shown, each of the multiple fixing ears 41 is provided with an installation port, and each of the multiple installation ports is connected to a locking bolt 42. Each of the multiple aligning ears 4 is provided with a threaded port, and the multiple locking bolts 42 are respectively threadedly connected to the multiple aligning ears 4.

[0026] It should be noted that: the cover 11 uses the fixing ear 41 to overlap and approach the alignment ear 4 on the outer tube 1, and then tightens the locking bolt 42 in sequence to close the whole device and form a basic protective shell.

[0027] refer to Figure 1 and Figure 2 As shown, the inner wall of the external tube 1 is provided with a gas flow channel, and a connecting pipe 53 is provided on the wall of one end of the external gas tube 52. The other end of the connecting pipe 53 is connected to the gas flow channel, and the other end of the gas flow channel is connected to the annular cavity inside the annular sealing ring 51.

[0028] It should be noted that the concealed design of the gas flow channel allows the gas to flow alternately between the external gas pipe 52 and the annular sealing ring 51, which facilitates daily maintenance and repair while ensuring pressurization.

[0029] refer to Figure 1 and Figure 3As shown, the control component includes a strip plate 6, which is fixedly connected to the outer wall of the external tube 1. An external air tube 52 is fixedly connected to the strip plate 6. A slide rod 61 is slidably connected to one end of the external air tube 52. A piston 62 is fixedly connected to one end of the slide rod 61. The piston 62 is located inside the external air tube 52. A pull plate 63 is fixedly connected to the other end of the slide rod 61.

[0030] It should be noted that: the pull plate 63 drives the slide rod 61 and piston 62 to move, so that the gas accumulated in the external air pipe 52 is discharged through the connecting pipe 53 and the gas flow channel, and is transported to the inside of the annular sealing ring 51.

[0031] The internal air pressure of the annular sealing ring 51 gradually increases, allowing it to fit more tightly against the inner wall of the cap 11, forming a highly efficient seal.

[0032] refer to Figure 1 and Figure 3 As shown, two plates 7 are symmetrically arranged on the strip plate 6. A fixing rod 71 is fixedly connected between the two plates 7. The pull plate 63 is slidably connected to the fixing rod 71. An adjusting shaft 72 is rotatably connected between the two plates 7. The adjusting shaft 72 is a threaded rod. The pull plate 63 is threadedly connected to the adjusting shaft 72. A turntable 8 is installed and connected to one end of the adjusting shaft 72.

[0033] It should be noted that rotating the turntable 8 drives the adjusting shaft 72 to rotate, causing the pull plate 63 to slide linearly along the fixed rod 71, which in turn drives the slide rod 61 and the piston 62 to move. The fixed rod 71 limits the direction of movement of the pull plate 63.

[0034] The working principle of the waterproof rotary rectifier component device provided by this utility model is as follows: the cover 11 is aligned with the alignment ear 4 on the external tube 1 by using the fixing ear 41 to close together, and the locking bolt 42 is tightened in sequence to close the whole device and form a basic protective shell.

[0035] The inner wall of the cover 11 fits against the outer wall of the built-in ring 5, so that the annular sealing ring 51 in the annular groove is tightly fitted with the inner wall of the cover 11 and forms an initial seal by contacting the inner wall of the cover 11. At this time, there is no additional pressure in the annular cavity, and the sealing effect depends on the elasticity of the sealing ring itself.

[0036] The rotating turntable 8 drives the adjusting shaft 72 to rotate, causing the pull plate 63 to slide linearly along the fixed rod 71, which in turn moves the slide rod 61 and the piston 62. This allows the gas accumulated in the external air pipe 52 to be discharged through the connecting pipe 53 and the gas flow channel. The internal air pressure of the annular sealing ring 51 gradually increases, allowing it to fit more tightly against the inner wall of the cover 11, forming a highly efficient seal. This results in a tighter fit between the annular sealing ring 51 and the cover 11, preventing liquid penetration.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
