Description

TECHNICAL FIELD

[0001] The application relates to the technical field of power equipment, in particular to a dynamic voltage restorer. BACKGROUND

[0002] In the present power supply system, a voltage restorer is widely used, mainly for adjusting the output voltage when the grid voltage appears short-time clipping, hysteresis or transient overvoltage and other abnormal conditions, so as to restore it to the normal voltage level. The common voltage restorer mainly comprises an input module, an output module and a control module. The input module is responsible for receiving the voltage of the grid, the control module calculates the adjusted voltage according to the received voltage and the set target voltage, and then the output module outputs the adjusted voltage to the grid. In the use process, the voltage restorer usually needs to be connected with the grid through wires to receive and output the voltage. The existing dynamic voltage restorer is laid on the ground, which is easy to be corroded at the bottom in a humid environment, and is inconvenient to move. Even the bottom may be infiltrated with water. The bottom cannot be ventilated while working, and the heat generated inside cannot be utilized for dehumidification.

[0003] In view of the above, we provide a dynamic voltage restorer to solve the above problems. SUMMARY

[0004] In view of the above, we provide a dynamic voltage restorer to solve the above problems.

[0005] A dynamic voltage restorer comprises a box body and a voltage recovery module. The bottom of the box body is provided with a ventilation module. The ventilation module comprises a ventilation pipe and a suction pipe. The lower surface of the suction pipe is rotationally provided with a rotating pipe. The outer surface of the rotating pipe is provided with a rotating force storage mechanism. The rotating force storage mechanism comprises a rotating groove, a cross rod and a one-way block. The rotating groove is opened on the outer surface of the rotating pipe. The surface of the rotating groove is lapped with the one-way block. The one-way block is rotationally arranged on one side of the cross rod. The bottom of the box body is provided with a lifting mechanism. The lifting mechanism comprises a push rod and a bottom sheet. The push rod is arranged on the lower surface of the box body. The protruding end of the push rod is provided with the bottom sheet. The bottom of the box body is slidingly provided with a lifting frame. The middle part of the lifting frame is integrally provided with a cross rod. The upper surface of the bottom sheet is provided with a channel opening mechanism. The upper surface of the rotating pipe is provided with an air inflation mechanism.

[0006] The above technical solution has the following advantages:

[0007] Through the upper and lower side ports designed on the bottom film, air can be blown to the bottom of the lifted bottom film, and air can be blown to the ground under the lifted bottom film, thereby achieving a double-sided blowing effect. The blowing direction of the lower side port corresponds to the position of the rotating tube. The rotating tube can transport the blown dust or liquid to the outside, and the bottom of the rotating tube can be deformed so that dust and liquid can quickly accumulate near the suction pipe. The suction position of the ventilation pipe is a module, and the heat generated by the module can be used to dehumidify the surface of the bottom film. When there is water seepage at the bottom of the box, the liquid can be automatically transported to the outside to prevent the bottom of the box from corroding faster.

DETAILED DESCRIPTION

[0021] The foregoing and other technical contents, features and effects of the present application will be described in detail below with reference to the accompanying drawings. Figures 1 to 12 In the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all referred to the accompanying drawings.

[0022] The present embodiment provides a dynamic voltage restorer, as shown in the accompanying drawings Figures 1-12 The accompanying drawings Figure 1 is the overall structure diagram of the present scheme, the accompanying drawings Figure 2 is the middle cut of the box 1, from Figure 2 It can be seen that the design points of the present scheme are all in the bottom of the box 1, so the accompanying drawings Figure 3 has adopted the cross-sectional view of the bottom of the box 1, from the accompanying drawings Figure 2 and the accompanying drawings Figure 3 It can be seen that the bottom of the box 1 is provided with a closed space, the present scheme takes out this closed space alone, which gets the accompanying drawings Figure 4 , the accompanying drawings Figure 4 is also cut in the middle, while the accompanying drawings Figure 5 , 6 and 8 are all derived from the accompanying drawings Figure 4 , the accompanying drawings Figure 7 In order to show the structure of the rotating pipe 4, it is separately displayed, the accompanying drawings Figure 9 Cut the upper part of this closed space, the structure distribution of the present scheme can be directly seen, the accompanying drawings Figure 10 The closed space is turned upside down, which is convenient for watching the bottom of the box 1, the accompanying drawings Figure 11 In order to show the internal shape of the cross rod 22, the inside of the cross rod 22 is cut, the accompanying drawings Figure 12In order to show the relationship between the partition tube and the water storage leaf 29, it is partially cut, first introduce the voltage recovery module of this scheme, voltage recovery module is the key to protect the normal circuit, system power grid needs to be transmitted to the user load, and between the system power grid and the user load is the voltage recovery module of this scheme, first the system power grid will be connected to the user load through the electrical, which has a switch to control, also the voltage recovery module normally provides the communication between the system power grid and the user load, only through a switch, the voltage recovery module is also provided with a line parallel to the above, which is the thyristor electronic switch, the inverter unit is connected in series between the thyristor electronic switch and the user load, the inverter unit is connected in series on one side of the storage capacitor, which can also be called storage capacitor cabinet, the grid voltage is normal when standby mode, thyristor electronic switch is turned on, and the communication switch between the system power grid and the user load is turned off, so the current is through the system power grid to the thyristor electronic switch and then to the user load, so the grid directly supplies power to the user load, the operation characteristics are high efficiency and real-time monitoring, when the grid voltage is abnormal, enter the compensation mode, quickly cut off the thyristor electronic switch, so that the grid and the load are isolated, at this time the storage capacitor supplies power to the load, when the grid voltage is restored, the thyristor electronic switch is turned on, the grid supplies energy to the storage capacitor at the same time, this is the recovery mode, when the equipment needs to be repaired, switch to the first loop to supply power (the circuit in which the grid is directly connected to the user load), this is the fault repair mode, this is the function of the voltage recovery module, as shown in the description Figure 3At this time, there is a rectangular block inside the box 1, which represents the voltage recovery module. Since the voltage recovery module can generate a certain amount of heat when it is working, this solution uses this heat source to set a ventilation pipe 2 directly below the voltage recovery module. The ventilation pipe 2 does not directly transport wind. A fan needs to be installed above the ventilation pipe 2. The fan draws wind to the bottom of the ventilation pipe 2, and the suction channel 33 draws the gas near the water storage blades 29 to the vicinity of the voltage recovery module to cool the voltage recovery module. The suction channel 33 also needs to be installed with a fan, that is, the suction channel 33 and the ventilation pipe 2 both need to be installed with a fan to realize the function. The fan belongs to the existing technology and is not introduced in detail. The purpose of the ventilation pipe 2 is to transport the air in a circular manner to the four groups of negative films 9. The transportation position is at the edge, and the rotating tube 4 of this solution is at the center. Let’s first introduce the structure at the center of this solution. In this solution, the ventilation pipe 2 is passed through by a suction pipe 3, and one side of the suction pipe 3 is connected to the outside of the box body 1, that is, an external device is required outside the box body 1, which can be a fan or a vacuum cleaner. A rotating pipe 4 is rotatably provided on the lower surface of the suction pipe 3, and a rotation seal is performed between the rotating pipe 4 and the suction pipe 3, and an anti-slip structure is provided, so that the rotating pipe 4 can rotate stably on the suction pipe 3. A middle frame 15 is integrally provided on the lower surface of the box body 1, and the middle frame 15 supports the sliding of the lifting frame 10 and the rotation of the rotating pipe 4. The middle frame 15 is relatively special, that is, it is distributed in the middle and also extends to the side. The next paragraph will introduce the effect of the middle frame 15 extending to the side. A circle is provided in the center of the middle frame 15 to facilitate the rotation of the rotating pipe 4. The extrusion groove 12 is opened on this circle. A reset spring 16 is provided between this circle and the rotating pipe 4. The reset spring 16 is a torsion spring that can be rotated and reset. Figure 5 The middle is in the untwisted state. The torsion of the return spring 16 relies on the cross bar 6. The cross bar 6 is arranged in a horizontal and integrated manner in the middle of the lifting frame 10. A one-way block 7 is provided on one side of the cross bar 6. The one-way block 7 rotates in one direction on one side of the cross bar 6. Figure 7 As shown in the instruction manual, Figure 7 The crossbar 6 is shown as suspended, but it is not. Instead, it is connected to the lifting frame 10, and the lifting frame 10 is hidden, so it appears to be suspended. Figure 7The one-way block 7 can only rotate upward and cannot rotate downward (a corresponding angle buckle is set at the rotation center of the cross bar 6 or an extension is set below the cross bar 6 to contact the bottom of the one-way block 7 to limit the bottom of the one-way block 7 to achieve one-way rotation. The above structure has been used many times in the prior art and is not a novel design. Therefore, the solution does not show how to achieve one-way clamping). When the cross bar 6 moves upward, it will move on the surface of the rotation groove 5, and the rotation groove 5 has to change its position to correspond to the upward movement of the cross bar 6, which makes the rotating tube 4 rotate, achieving the effect of torsional reset spring 16. The top of the rotating groove 5 is provided with an outlet, which just corresponds to the one-way block 7 being unable to control the rotation of the rotating tube 4. At this time, due to the torsion reset spring 16, the reset spring 16 will quickly reset, thereby achieving the effect of controlling the rotation of the rotating tube 4. When the one-way block 7 reaches the top and then reaches the bottom, the one-way block 7 needs to be rotated. A torsion spring is also provided on one side of the one-way block 7, and one side of the one-way block 7 (the side close to the rotating groove 5) is in the shape of a downward slope. This slope makes it easy to twist the one-way block 7 when it moves up and down, so that the one-way block 7 can be easily rotated and reaches the attached part of the instruction manual. Figure 7 The position of the rotating tube 4 can be moved upward again to realize the rotation and storage of the rotating tube 4. The rotation of the rotating tube 4 can achieve the effect of rotating in the direction of suction, and can make the expansion piece 19 inflated. The expansion piece 19 is at the bottom of the rotating tube 4. The expansion piece 19 is similar to an air bag, but the expansion piece 19 is made of two materials. The first is plastic, and the plastic material is distributed on the upper side of the expansion piece 19. The second is the air bag edge 21. The air bag edge 21 is distributed on the lower side of the expansion piece 19. The plastic edge 20 can be deformed but not stretched, and the air bag edge 21 can not only be deformed but also stretched, so that when the expansion piece 19 is inflated, the length of the air bag edge 21 is greater than the length of the plastic edge 20. Under the obstruction of the ground, the shape of the expansion piece 19 can only be concave upward, so that the shape of the expansion piece 19 is similar to a bowl shape ( Figure 7 The actual shape is not shown in the attached figure. Figure 7 It is necessary to show that the expansion piece 19 is in the shape of a bowl. The reason why it is still in the uninflated state is to substitute the following Figure 7 The unexpanded state needs to be shown in the figure, because the unexpanded state can be clearly expressed in this solution. If the expanded state is shown, the unexpanded state will be difficult to show. One state requires two figures to show, which greatly increases the number of drawings. Therefore, it is not shown. It is clear that the specification is attached. Figure 7 The expansion piece 19 should be in an expanded state, while the figure shows an unexpanded state). In this way, the expansion piece 19 can be deformed into a concave shape, which can collect dust and a small amount of liquid, achieving the effect of upward suction. Figure 7In the introduction, it is introduced above that the one-way block 7 rotates from bottom to top and the tube 4 rotates, and then releases and resets. Figure 7 Mainly, in the process of the one-way block 7 moving, the rotating tube 4 will rotate clockwise, and the clockwise rotation of the rotating tube 4 will drive the extrusion frame 11 to rotate (the extrusion frame 11 can slide up and down on the rotating tube 4), and the extrusion frame 11 also rotates clockwise, while the extrusion groove 12 does not move, so that the extrusion frame 11 will reach the inclined groove of the extrusion groove 12 (the extrusion groove 12 is an annular groove with an inclined groove on the top), and the extrusion spring 14 is squeezed, causing one side of the extrusion frame 11 to easily enter the inclined groove and reach the top of the inclined groove, so that the extrusion frame 11 is equivalent to the upward movement of the rotating tube 4. The upward movement of the extrusion frame 11 will cause the air inside the expansion piece 19 to be sucked into the inner groove 13. The inner groove 13 can store air inside the rotating tube 4, and the inside is connected to the expansion piece 19 through the connecting pipe 18, so the gas in the expansion piece 19 can be sucked into the memory, so that the expansion piece 19 is deflated ( Figure 7 The middle is dry, actually Figure 5 In the expanded state), since the one-way block 7 reaches the top, the rotating tube 4 is released, so the rotating tube 4 rotates counterclockwise, so that the extrusion frame 11 re-enters the chute under the counterclockwise action (before entering the chute, the extrusion spring 14 is in a stretched state, so it can enter the chute, and the entrance of the chute can be set wider for easy entry), and reaches the lower side of the branch marked 12, that is, the extrusion frame 11 is equivalent to the rotating tube 4 moving downward, discharging the gas inside the inner groove 13, completing the expansion of the expansion piece 19, and the expansion piece 19 expands to achieve a deformation effect, so that its surface can store dust and liquid. To achieve the effect of faster adsorption, an inner rod 17 is slidingly provided inside the rotating tube 4 and the suction tube 3. The function of the inner rod 17 is to block the bevel ring. The inclined ring 34 is to facilitate the liquid to flow into the water pipe 30. A valve 31 is provided on one side of the delivery pipe. There are two types of valves 31. The first is a one-way valve. The suction pipe 3 can enter the water pipe 30, but the delivery pipe cannot enter the suction pipe 3 (neither gas nor liquid). This ensures that the suction source of the suction pipe 3 can only reach the bottom hole at the bottom of the rotating tube 4 for suction (the bottom hole is opened on the upper side of the plastic edge 20 at the bottom of the rotating tube 4, as shown in the attached manual). Figure 9The upper side of the label 19, both sides of the curved connecting pipe 18), the second is an electric valve 31, which is closed when the suction pipe 3 is sucking air and opened when the suction pipe 3 is not sucking air. Since the one-way valve and the electric valve 31 are of different shapes, a simple cylinder is used instead, so that the liquid will reach the top of the bevel ring and reach the water pipe 30. The top of Lei Gang blocks the top and bottom of the bevel ring. In the normal state, the inclined ring 34 needs to be moved upward to open the channel. The lower side of the bevel ring is provided with a spring that can be pulled. In this way, squeezing this spring can make the long rod display move. The spring is squeezed by the suction force of the suction pipe 3. Because the elastic force of this spring is very small, when the suction force is large, the inner rod 17 can be moved upward to achieve the effect of opening the channel, and the suction pipe 3 can be automatically blocked when it is not working, so that the liquid can reach the water pipe 30.

[0023] The previous paragraph introduces the middle structure of this scheme, and this paragraph introduces the side structure of this scheme, as shown in the attached manual. Figure 11As shown, the scheme has four push rods 8, push rod 8 is electric push rod 8, has self locking function, the top of push rod 8 is installed on the box 1, the lower side extension end installs the bottom sheet 9, and the bottom sheet 9 represents the bottom disc of the box 1, and is also contacted with the ground, and the problem solved by the scheme is to deal with the bottom damp, so the problem to be solved is the bottom damp and decay of the bottom sheet 9, so that the four push rods 8 of the scheme can control the bottom sheet 9 to be lifted two by two (two opposite ones), so that the remaining two bottom sheets 9 are still supporting, and the supporting area is large, without worrying about the stability of the box 1, and the lifting frame 10 is pressed on the four bottom sheets 9, so that no matter which two groups are lifted, the lifting frame 10 can be moved upward, and the lifting frame 10 of the scheme moves upward to make the cross bar 6 move upward, which corresponds to the previous paragraph, the spring between the lifting frame 10 and the middle frame 15 makes the lifting frame 10 reset when the bottom sheet 9 resets downward, the scheme utilizes the interaction of the lifted bottom sheet 9 and the bottom sheet 9 that has not been lifted, the shape of the bottom sheet 9 of the scheme is a triangle, and since the shape of the bottom of the box 1 is not likely to be a square, the cut is not an isosceles right triangle, actually the isosceles right triangle is the best, and it is because the shape is similar to the isosceles right triangle, so that when the two side columns 26 of the two lifted bottom sheets 9 blow, the dust or liquid can be blown to the position of the rotating pipe 4 through the lower side opening 28, and because the bottom sheet 9 that has not been lifted, the shape can make the blown dust reach the rotation of the rotating pipe 4, so that the lifted bottom sheet 9 can make the side column 26 blow the ground, and the above introduces that the air inlet of the ventilation pipe 2 is the high temperature gas of the module, so that the bottom ventilation effect of the bottom sheet 9 can be achieved, the bottom sheet 9 that has not been lifted can blow through the upper side opening 24, and the position opposite to the bottom of the lifted bottom sheet 9, so that the bottom sheet 9 that has not been lifted can be used, and the bottom ventilation effect of the bottom sheet 9 can be achieved, the lower side opening 28 in the lifted bottom sheet 9 (the bottom sheet 9 has upper side opening 24 and lower side opening 28 at the same time, which represents the lifted bottom sheet 9 in the introduction) will be connected, because the side column 26 is sealingly and slidably arranged on the lower surface of the ventilation pipe 2, so the side column 26 will move upward, and the lifting valve 27 will be lifted upward, and the lifting valve 27 will be opened (the spring below the lifting valve 27 can be reset), and the ventilation pipe 2 can supply air to the lower side opening 28, so that the ventilation effect of the lower side opening 28 can be achieved, and the through hole 23 is arranged above the lifting valve 27, and the through hole 23 can be connected with the cross rod 22, as shown in the drawings Figure 8As shown, for example, at this time, the bottom plate 9 on the right moves upward, which will drive the cross rod 22 to move upward (the cross rod 22 on the bottom plate 9 itself), and the cross rod 22 on the adjacent bottom plate 9 will drive it to move upward. Because the cross rods 22 are arranged crosswise, and the cross position passes over the adjacent upper part, this will cause the cross rod 22 on the left to move upward (the bottom plate 9 on the left does not move). The cross rod 22 moves upward so that the through hole 23 and the hidden channel 25 correspond to each other, achieving the effect of opening the channel, that is, water is transported to the boarding port through the hidden channel 25, and the upper side port 24 is in an oblique upward position, so it acts on the bottom of the raised bottom plate 9. The cross rod 22 is slidably set on the bottom plate 9 and has a spring for reset. Finally, the water storage leaf 29 of this scheme is introduced. The water storage leaf 29 is rotatably set on both sides of the box body 1. The interior is hollow and can store liquid. In order to balance the liquid inside the water storage leaf 29, a partition tube is inserted in the rotation center of the water storage leaf 29. The middle part of the partition tube is a long plate. ​As shown, there is a plate in the middle of the water storage blade 29, which is the separator. At this time, the liquid is all on the lower right side and is separated from the left and right sides so that this part of the liquid is stored and cooled. When the push rod 8 works, the lifting frame 10 moves upward. The upward vertical movement of the lifting frame 10 will cause the water storage blade 29 to rotate (the edge of the lifting frame 10 extends and overlaps the notch 32). The rotation of the water storage blade 29 causes the liquid on the right to move to the left, that is, water with low temperature. The suction end of the suction channel 33 corresponds to the position of the water storage blade 29, so that the wind inhales low-temperature gas from the position of the water storage blade 29 to solve the problem of high module temperature. The separator is fixed and should be installed on the ground. It is blocked on the lower side of the rotation center of the water storage blade 29 and has a Opening, so that the liquid level is higher than the upper side of the rotation center will be discharged to the outside. Summarizing the effect of this solution, through the upper side port 24 and the lower side port 28 designed by the bottom film 9, the bottom of the lifted bottom film 9 can be blown, and the ground below the lifted bottom film 9 can be blown to achieve the effect of double-sided blowing, and the blowing direction of the lower side port 28 corresponds to the position of the rotating tube 4. The rotating tube 4 can transport the blown dust or liquid to the outside, and the bottom of the rotating tube 4 can be deformed so that the dust and liquid can quickly accumulate near the suction pipe 3, and the suction position of the ventilation pipe 2 is a module, which can use the heat generated by the module to dehumidify the surface of the bottom film 9, and can automatically transport the liquid to the outside when there is water seepage at the bottom of the box body 1 to prevent the bottom of the box body 1 from accelerating Corrosion rate, a ventilation module is provided at the bottom of the box 1, and the ventilation module includes a ventilation pipe 2 and an air suction pipe 3.
