Abstract
Description
Technical Field

[0002] In the field of high-voltage motors, with the rapid development of industrial automation, the requirements for motor control systems are increasing. The high-voltage motor control cabinet is a key component in the motor system, which is used to monitor, control and protect the motor. It usually includes the control cabinet body, electrical components, ventilation system and other parts. The control cabinet obtains the operating status of the motor through various sensors, and executes the corresponding control strategy after processing by the logic controller to ensure the safe, efficient and stable operation of the motor.
[0003] Traditional high-voltage motor control cabinets have some problems in ventilation design. Simple fans are usually used, which cannot meet the changing needs of the motor under different workloads. This may cause the temperature inside the control cabinet to be too high, affecting the performance and life of the motor. At the same time, the line layout of traditional control cabinets is usually relatively fixed. When new lines need to be added, the layout needs to be changed, or maintenance is required, the operation is cumbersome and the maintenance cost is high, which restricts the flexibility and maintainability of the control system.
[0004] In summary, traditional high-voltage motor control cabinets have a series of technical problems in ventilation and heat dissipation, line layout, humidity control, system scalability and maintenance. At the same time, traditional motor control cabinets have some shortcomings in ventilation and heat dissipation. Traditional control cabinets usually adopt simple vent designs, which are difficult to meet the flexible adjustment needs under different working conditions. Utility Model Content

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0031] Example 1
[0032] Reference Figures 1 to 5 , which is the first embodiment of the utility model, provides a ventilation mechanism, including a control cabinet 300, a ventilation assembly 100 and a locking component 303. The ventilation volume is regulated by the ventilation assembly 100, and the air intake is increased when the temperature is high, and the incoming air is dehumidified to prevent the humidity inside the control cabinet body 301 from being too high. It includes a driving component 102 including a box body 102a arranged on one side of the mounting seat 101, an elastic member 102b arranged on the inner surface of the box body 102a, a piston 102c arranged at one end of the elastic member 102b, and a moving bar 102d arranged at one end of the piston 102c and extending out of the outer surface of the box body 102a.
[0033] Specifically, the box 102a and the piston 102c are filled with heat-expanding gas. When the heat-expanding gas evaporates, there is an overload pressure inside the box 102a to push the piston 102c. The piston 102c can slide in the box 102a. The elastic member 102b is a spring with one end connected to the inner surface of the box 102a and the other end connected to the outer surface of the piston 102c.
[0034] The linkage component 103 includes a sliding sleeve 103a disposed on one side of the moving bar 102d, a sliding block 103b disposed inside the sliding sleeve 103a, and a transmission shaft 103c disposed at one end of the sliding block 103b.
[0035] Furthermore, during the sliding of the moving bar 102d, the sliding sleeve 103a can be driven to move. There is also a waist-shaped sliding groove inside the sliding sleeve 103a. The slider 103b is a rectangular block and its long side slides along the waist-shaped sliding groove, so that the sliding sleeve 103a can drive the slider 103b in its inner cavity to slide during the movement, thereby enabling the slider 103b to drive the transmission shaft 103c to move.
[0036] The linkage component 103 further includes a rotating ring 103d disposed on the outer surface of the transmission shaft 103c, and the rotating ring 103d is mounted on the mounting seat 101 so as to be rotatable.
[0037] More preferably, the transmission shaft 103 c drives the rotating ring 103 d on the outer surface to rotate during the sliding process, so that the rotating ring 103 d can rotate on the mounting seat 101 .
[0038] The sliding sleeve 103a has an inner cavity, and the moving bar 102d drives the sliding block 103b to slide in the inner cavity of the sliding sleeve 103a.
[0039] The shielding component 104 includes a pull rod 104a disposed at one end of the transmission shaft 103c, a rotatable blade 104b disposed at the end of the pull rod 104a, and a filter hole 104c opened on the outer surface of the blade 104b.
[0040] Furthermore, the transmission shaft 103c drives the pull rod 104a at one end to move during sliding, and the pull rod 104a drives the blade 104b at the end to rotate during movement. The larger the rotation angle of the blade 104b, the more the opening and closing degree of the filter hole 104c on the outer surface is adjusted.
[0041] One end of the blade 104b is rotatably disposed on the inner surface of the mounting seat 101, and there are at least five blades 104b equidistantly distributed around the circumference.
[0042] Among them, there are five blades 104b and a circular array is arranged on the inner wall of 101. The blades 104b have three arc-shaped outer walls. Adjacent blades 104b fit together and as the blades 104b rotate, the blades 104b together form a circular hole coaxial with the vent. The greater the rotation angle of the blade 104b, the smaller the diameter of the circular hole, thereby adjusting the degree of opening and closing of the vent, adjusting the size of the vent of the control cabinet body 301, thereby adjusting the air volume and heat dissipation effect.
[0043] In summary, when the temperature inside the control cabinet body 301 of the high-voltage motor changes during use, the gas inside the box body 102a disposed on the inner wall of the control cabinet body 301 evaporates, thereby increasing the volume and pushing the piston 102c to slide outward along the box body 102a, thereby driving the moving bar 102d to slide, thereby causing the sliding sleeve 103a connected to the moving bar 102d to slide, thereby driving the slider 103b to move along with the sliding sleeve 103a. Because the slider 103b is rotatably disposed on the end face of the transmission shaft 103c, the transmission shaft 103c can only rotate, thereby the slider 103d is rotated. 03b drives the transmission shaft 103c to rotate while sliding in the sleeve 103a, and drives the rotating ring 103d to rotate, thereby driving the blades 104b rotatably connected thereto to rotate outward, and increasing the diameter of the circular hole formed, thereby increasing the air intake, and at the same time absorbing moisture through the moisture-absorbing block inside the filter hole 104c to prevent excessive humidity inside the control cabinet body 301, and at the same time improve the heat dissipation effect to achieve better heat dissipation. When the heat dissipation is completed, the blades 104b are automatically reset under the drive of the first elastic member 102b to prevent a large amount of humid gas from entering the interior and causing a short circuit.
[0044] Example 2
[0045] Reference Figure 1 , 2 And 4, this embodiment provides a supply assembly 200 that cooperates with the ventilation assembly 100, which includes a control cabinet 300, which includes a control cabinet body 301 for carrying the ventilation assembly 100, a mounting hole 302 arranged on the outer surface of the control cabinet body 301, and a supply component 203 on the outer surface of the control cabinet body 301.
[0046] Specifically, the replenishment assembly 200 includes a one-way gas injection valve 202 disposed on the control cabinet body 301, and a replenishment pipe 201 disposed at one end of the one-way gas injection valve 202 and extending to the interior of the box body 102a.
[0047] The replenishment assembly 200 includes a one-way gas injection valve 202 disposed on the control cabinet body 301 , and a replenishment pipe 201 disposed at one end of the one-way gas injection valve 202 and extending to the interior of the box body 102 a .
[0048] The gas injection valve 202 is sealedly connected to the box body 102a through the supply pipe 201.
[0049] Preferably, since the piston 102c in the box 102a will slide, the sliding will produce a gap, and the heat expansion gas in the box 102a will volatilize. When replenishment is needed, the heat expansion gas is injected through the gas injection valve 202, and enters the box 102a through the supply pipe 201 to complete the replenishment of the heat expansion gas. The heat expansion gas can be helium or nitrogen, preferably nitrogen. According to Gay-Lussac's law, when the pressure of a certain mass of gas remains unchanged, the temperature rises by 1°C, and the increase in volume is equal to 1 / 273 of its volume at 0°C. Therefore, when the temperature is higher than 80°C, the temperature in the inner cavity can expand, and the thrust of the expansion is greater than the tension of the spring.
[0050] In summary, when in use, the heat expansion gas in the box 102a expands, and the heat expansion gas is replenished to the box 102a through the gas injection valve 202, and enters the box 102a through the supply pipe 201 to complete the supply of the heat expansion gas.
[0051] Example 3
[0052] Reference Figures 1 to 5 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a ventilation mechanism, including a ventilation component 100 and a locking component 303. The locking component 303 is detachably connected to the mounting cylinder 303b, so that the vent hole can not only be used as a ventilation hole, but also can be used as a spare wire pipe for wiring when new lines are added later.
[0053] Specifically, a ventilation component includes a mounting base 101 for being set on a cabinet, a driving component 102 set on the mounting base 101, a linkage component 103 connected to the driving end of the driving component 102, and a shielding component 104 set at one end of the linkage component 103.
[0054] The driving component 102 is installed on the mounting seat 101, and the driving component 102 is used to connect and drive the linkage component 103 at the driving end to move, so that the linkage component 103 links the shielding component 104 at one end to move, thereby achieving a ventilation effect.
[0055] The locking component 303 is arranged at one end of the mounting base 101, and includes a guide groove 303a arranged in the mounting base 101, a mounting tube 303b extending from one end of the guide groove 303a, a limit block 303c arranged on the outer surface of the mounting tube 303b and cooperating with the guide groove 303a, and a limit groove 303d movably engaged with the limit block 303c.
[0056] Specifically, the locking component 303 includes a mounting tube 303 b movably disposed inside the vent hole and a mounting hole 302 disposed on the outer wall of the control cabinet body 301 , and the mounting tube 303 b is movably engaged with the mounting hole 302 .
[0057] The inner wall of the mounting hole 302 is provided with a guide groove 303a and a limit block 303c respectively.
[0058] More preferably, the outer wall of the installation cylinder 303b is symmetrically provided with limiting blocks 303c, and the limiting blocks 303c can slide freely in the guide groove 303a.
[0059] Furthermore, the limiting block 303c is a square block, and the mounting tube 303b slides through the inside of the mounting hole 302 and can be further fixed by the movable engagement of the slot of the mounting seat 101. At the same time, the laying line slides through the mounting tube 303b, so that the mounting hole 302 and the mounting tube 303b can be used as spare wire tubes. When not in use, the mounting tube 303b can be removed and only serves as ventilation, which is simple, convenient and practical.
[0060] In summary, when in use, first align the installation cylinder 303b with the installation seat 101, so that the installation cylinder 303b is aligned with the inner wall of the guide groove 303a and slides in, and then continue to push the rotating installation cylinder 303b inward to make the limit block 303c on the outer wall of the installation cylinder 303b and the limit groove 303d movably engage with each other to play a fixing role, so that the cable to be laid can be laid through the installation cylinder 303b, so that the installation cylinder 303b serves as a spare wire tube.
