TECHNICAL FIELD

[0001] The present application relates to the field of control cabinet, in particular to a high-frequency stabilizer. BACKGROUND

[0002] The stabilizer refers to one kind of device designed to maintain constant automatically, which is composed of voltage regulating circuit, control circuit and etc. When the input voltage or load changes, the control circuit samples, compares and amplifies, and then drives the servo motor to rotate, so that the position of the stabilizer carbon brush changes, and the output voltage is kept stable by automatically adjusting the turns ratio. The stabilizer with large capacity also works by the principle of voltage compensation.

[0003] In the related art, a cooling fan is installed on the stabilizer to cool the stabilizer by rotating. The rotation of the cooling fan consumes additional electric energy, which increases the power consumption of the stabilizer, and needs to be improved. SUMMARY

[0004] In order to reduce the power consumption of the stabilizer, the present application provides a high-frequency stabilizer.

[0005] The high-frequency stabilizer provided by the present application adopts the following technical solution:

[0006] A high-frequency stabilizer comprises a mounting shell and a stabilizer body arranged in the mounting shell. A plurality of heat dissipation holes are formed in the mounting shell, and the heat dissipation holes are used for air exchange in the mounting shell. A refrigeration air bag is arranged on the mounting shell, and a refrigeration piece is arranged in the refrigeration air bag. The refrigeration piece is used for cooling the gas in the refrigeration air bag. An air outlet is formed in the refrigeration air bag, and a sealing cover is hingedly connected to the refrigeration air bag. The sealing cover is used for covering the air outlet. A thermal expansion and contraction block is arranged on the mounting shell, and the thermal expansion and contraction block is used for expanding and pressing the refrigeration air bag. An air inlet is formed in the refrigeration air bag, and the air inlet is used for inflating the refrigeration air bag. A sealing piece is arranged on the refrigeration air bag, and the sealing piece is used for plugging the air inlet.

[0007] By adopting the above technical solution, when the voltage or load changes, the servo motor in the stabilizer body moves to make the temperature in the mounting shell rise. After the temperature rises, the thermal expansion and contraction block expands and presses the refrigeration air bag, so that the air pressure in the refrigeration air bag rises. At this time, the air pressure in the refrigeration air bag is greater than the air pressure in the mounting shell, so that the sealing cover rotates away from the refrigeration air bag to open the air outlet. The cold air in the refrigeration air bag enters the mounting shell to cool the stabilizer body. The air inlet is used for inflating the refrigeration air bag, which is convenient for cooling next time. When the temperature in the mounting shell rises, the cold air in the refrigeration air bag is rushed into the mounting shell to cool the mounting shell. Compared with using the cooling fan, no electric energy is consumed, which is conducive to reducing the energy consumption of the stabilizer, and further conducive to embodying the concept of energy saving and environmental protection.

[0009] By using the above technical scheme, the elastic member is added to the sealing cover, and the force required for the sealing cover to open the air outlet is increased, so that when the sealing cover opens the air outlet, the pressure difference between the refrigeration air bag and the installation shell is increased, and the flow rate of the cold air in the refrigeration air bag entering the installation shell is increased, which is beneficial to promote the circulation of the air flow in the installation shell and improve the heat dissipation effect.

[0010] Preferably, the refrigeration air bag comprises a storage frame arranged on the installation shell and an air bag body arranged on the installation shell, the sealing cover, the sealing member, the air outlet and the air inlet are arranged on the air bag body, the air bag body is attached to the storage frame, the refrigeration member is arranged in the storage frame, a driving rod one is slidably arranged on the storage frame and slides out of the storage frame, the thermal expansion and contraction block drives the driving rod one to move, a driving rod two is slidably connected to the storage frame and abuts against the sealing cover, the sliding direction of the driving rod two is parallel to the distribution direction of the driving rod two, a guide surface is arranged on the driving rod one and inclined to the sealing cover, and the guide surface is used to abut against the driving rod two.

[0011] By using the above technical scheme, in order to make the flow rate of the gas in the air bag body entering the installation shell larger, the sealing cover is opened only when the air bag body is extruded to the maximum deformation degree, the elastic coefficient of the elastic member is selected in a smaller range, when the elastic coefficient is small, the sealing cover is opened when the air bag body is not extruded to the maximum degree; when the elastic coefficient is large, the sealing cover is closed when the air bag body is extruded to the maximum degree, and the selection difficulty of the elastic member is large. By adding the driving rod one and the driving rod two, the thermal expansion and contraction block expands and extrudes the air bag body, when the surface of the air bag body abuts against the storage frame, the air bag body is extruded to the maximum deformation degree, the thermal expansion and contraction block abuts against the driving rod one through the air bag body, the driving rod one extends into the storage frame, the driving rod one moves the driving rod two along the inclined direction of the guide surface to the direction close to the sealing cover through the guide surface, and the driving rod two pushes the sealing cover to move away from the air bag body to open the air outlet. By the cooperation between the thermal expansion and contraction block and the driving rod one and the driving rod two, when the elastic coefficient of the elastic member is large, the driving rod two can push the sealing cover away from the air outlet, so that the elastic coefficient range of the elastic member is increased when the elastic member is selected, which is beneficial to reduce the selection difficulty.

[0022] Preferably, the thermal expansion and contraction block is located below the pressure stabilizing body.

[0039] With reference to Figure 2 The air bag body 31 is provided with an air inlet 311 and an air outlet 312. The air outlet 312 is located at the side of the air bag body 31 close to the installation cavity two 132. The air outlet 312 is projected on the frame body 321 in the horizontal direction.

The one-way air inlet valve 41 is fixed on the air bag body 31 through the air inlet pipe 313.

In the embodiment, the elastic element 53 is a torsion spring.

[0042] With reference to Figure 2 The housing 11 is provided with a containing cavity 16 below the installation cavity one 131 and the installation cavity two 132, the housing 11 is fixed with a thermal expansion and contraction block 17 in the containing cavity 16, and the housing 11 is provided with a plurality of through holes 18 to communicate the installation cavity two 132 and the containing cavity 16, so that the heat in the installation cavity two 132 is transmitted to the containing cavity 16.

[0043] With reference to Figure 2 The housing 11 is slidably connected with a push rod 6 near the air bag body 31, one end of the push rod 6 penetrates the housing 11 and extends into the containing cavity 16, the push rod 6 is in a “T” shape, the opposite sides of the push rod 6 parallel to the vertical direction abut against the thermal expansion and contraction block 17 and the air bag body 31 respectively, the thermal expansion and contraction block 17 abuts against the surface of the air bag body 31 through the push rod 6, when the temperature in the containing cavity 16 rises, the thermal expansion and contraction block 17 expands to move the push rod 6 towards the frame 321, and the push rod 6 extrudes the air bag body 31 to deform the air bag body 31.

[0044] With reference to Figure 2 And Figure 3 The frame 321 is slidably connected with a driving rod one 3212 and a driving rod two 3213, the sliding direction of the driving rod one 3212 is parallel to the sliding direction of the push rod 6, and the driving rod one 3212 slides to extend into or out of the frame 321. When the thermal expansion and contraction block 17 is not in the expansion state, one end of the driving rod one 3212 near the push rod 6 extends out of the frame 321, the end of the driving rod one 3212 extending out of the frame 321 is located on the moving path of the push rod 6, the push rod 6 is used to abut against the driving rod one 3212, and the driving rod one 3212 is driven to move to extend into the frame 321.

[0045] With reference to Figure 2 And Figure 3, the end of the driving rod one 3212 away from the push rod 6 is machined to form a guide surface 3214, the guide surface 3214 is arranged obliquely, and the guide surface 3214 is inclined towards the direction close to the push rod 6.

When the driving rod one 3212 moves upward and extends into the frame 321 under the action of the thermal expansion and contraction block 17, the guide surface 3214 abuts against the driving rod two 3213, so that the driving rod two 3213 moves towards the air inlet 311 and pushes open the cover plate 51.

[0046] In actual use, the shell 11 is installed into a control cabinet, and the voltage stabilizing body 2 is in communication with a circuit. When the voltage changes, the voltage stabilizing body 2 works to generate heat, so that the temperature in the installation cavity two 132 rises, the temperature in the installation cavity two 132 is transmitted to the containing cavity 16, so that the temperature in the containing cavity 16 rises, and then the thermal expansion and contraction block 17 expands to drive the push rod 6 to press the air bag body 31. Along with the gradually reduced distance between the push rod 6 and the frame 321, the air pressure difference between the air bag body 31 and the installation cavity two 132 increases. When the push rod 6 moves the driving rod one into the frame 321, the driving rod two 3213 moves along the guide surface 3214 towards the air outlet 312 and pushes open the cover plate 51, so that the air outlet 312 is opened, and the cold air in the air bag body 31 quickly enters the installation cavity two 132, promotes the air circulation in the installation cavity two 132, and cools the voltage stabilizing body 2 at the same time.

[0047] When the gas in the air bag body 31 enters the installation cavity two 132, the cold air descends into the containing cavity 16, the hot air rises to the vicinity of the opening two 142, the cold air descending into the containing cavity 16 causes the temperature of the containing cavity 16 to drop, and the thermal expansion and contraction block 17 shrinks, so that the push rod 6 moves away from the frame 321 under the action of gravity, the driving rod one 3212 extends out of the frame under the action of gravity, the driving rod two 3213 loses the support of the driving rod one 3212, and the driving part two moves into the frame 321 and abuts against the guide surface 3214 under the cooperation of the elastic part 53 and the cover plate 51.

[0048] Since the push rod 6 no longer presses the air bag body 31, the air bag body 31 expands under the action of the elastic force thereof, the expansion of the air bag body 31 causes the hot air to enter the air bag body 31 from the opening two 142 along the air inlet pipe 313, and the hot air is cooled by the refrigeration part, so that the hot air in the installation cavity two 132 is reduced, and the temperature at the voltage stabilizing body 2 is reduced,

[0049] The implementation principle of the high-frequency voltage stabilizer in the embodiment of the application is as follows: when the voltage stabilizer body 2 works, the temperature rises, and through the cooperation between the thermal expansion and cold contraction block 17, the push rod 6, the first driving rod 3212 and the second driving rod 3213, the cold air in the air bag body 31 enters the installation cavity two 132 to cool the voltage stabilizer body 2, so that the power consumption in the working process of the voltage stabilizer is reduced, and the concept of energy saving and environmental protection is embodied.

[0050] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: all equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
