Description

[0001] The present invention relates to the field of inverters, and in particular to a protective inverter for an energy storage power supply system. Background Art

[0002] The inverter is a common device in the energy storage power supply system. For example, the existing Chinese patent: CN117729760B discloses a protective device for a photovoltaic inverter. The protective device is provided with a protective mechanism, and cold water enters the heat dissipation pipe through the water inlet pipe to cool the components. Water is added to the counterweight box according to the temperature changes in different seasons, so that the adjustment component moves and the size of the gap on the protective shell is adjusted to facilitate air cooling. When the temperature is high, water is added to the counterweight box, and the adjustment component enlarges the vent of the protective shell to increase the ventilation volume and accelerate the cooling. On rainy days, water is released from the counterweight box to reduce the vent to prevent rainwater from entering the protective shell and reduce the damage to the components caused by humid air.

[0029] The inverter body 2 is fixedly connected with the heat dissipation pipe 101, and the heat dissipation pipe 101 is connected to the bottom box 1; the heat dissipation pipe 101 is fixedly connected with the circulation pump 102; the inverter body 2 is slidably connected with two U-shaped plates 103 distributed on the left and right, and the total length of the two U-shaped plates 103 is greater than the width of the inverter body 2; the inverter body 2 is fixedly connected with an elastic cloth 104, and the elastic cloth 104 is fixedly connected to the U-shaped plate 103, and the elastic cloth 104 is made of heat-insulating material; the heat dissipation pipe 101 is connected with two electrically controlled three-way valves 105; each electrically controlled three-way valve 105 is connected with a connecting pipe 106, and the connecting pipe 106 is fixedly connected to the limiting groove 2a; the inverter body 2 is bolted with an electric push rod Ⅰ107, and the telescopic end of the electric push rod Ⅰ107 is fixedly connected to the U-shaped plate 103, and the electric push rod Ⅰ107 can move in both directions.

[0030] It also includes a round tube 109 and a one-way valve 1010; one of the electrically controlled three-way valves 105 is connected to the round tube 109; the inverter body 2 is fixedly connected with a plurality of one-way valves 1010, and the one-way valves 1010 only allow the fluid to move from top to bottom.

[0031] It also includes a dustproof net 1011, a guide plate 1012 and a guide tube 1013; each U-shaped plate 103 is fixedly connected to a dustproof net 1011, and the dustproof net 1011 is fixedly connected to the inverter body 2, and the dustproof net 1011 is made of flexible material; one of the U-shaped plates 103 is rotatably connected to the guide plate 1012, and a torsion spring is provided between the guide plate 1012 and the U-shaped plate 103; the protector is connected to the inverter body 2 and fixedly connected to two guide tubes 1013 distributed front and back.

[0032] It also includes a filter 1014, a spring body I 1015 and an elastic rope 1016; the inverter body 2 is fixedly connected with a plurality of filters 1014 distributed on the left and right; the filters 1014 on the left and right are connected by a plurality of spring bodies I 1015; the outermost filter 1014 on each side is fixedly connected with a plurality of elastic ropes 1016, and the elastic ropes 1016 are fixedly connected to the elastic cloth 104, and the elastic ropes 1016 are fixedly connected to the U-shaped plate 103.

[0033] The heat dissipation pipe 101 is provided with a temperature insulation ring 101 a .

[0034] When used under high temperature conditions in summer, first inject cooling water into the bottom box 1, then put the bottom box 1 into a pre-dug pit, and then bury the bottom box 1 underground for fixation, the burial depth just covers the upper side of the bottom box 1. During normal use, control the electric push rod Ⅰ107 to extend and push the two U-shaped plates 103 apart, and the two U-shaped plates 103 move back to back on the inverter body 2. At the same time, the two U-shaped plates 103 stretch the lower side of the elastic cloth 104, so that the lower left and right ends of the elastic cloth 104 are spaced from the left and right sides of the inverter body 2 respectively, as shown in FIG. Figure 2 As shown, the initially electrically controlled three-way valve 105 is closed, and the heat dissipation pipe 101 is not connected to the connecting pipe 106. Then the circulating pump 102 is controlled to start, and the cooling water in the bottom box 1 is pumped into the heat dissipation pipe 101 through the right end of the heat dissipation pipe 101, and then flows back into the bottom box 1 from the left end of the heat dissipation pipe 101, thereby dissipating the heat of the inverter body 2. Since the bottom box 1 is buried underground, the cooling water in the bottom box 1 can be cooled, thereby enhancing the cooling and heat dissipation effect on the inverter body 2. The temperature insulation ring 101a on the heat dissipation pipe 101 can isolate the cooling water in the heat dissipation pipe 101 from the contact with the external hot air, thereby ensuring the cooling efficiency of the cooling water in the heat dissipation pipe 101.

[0035] At the same time, the outside air is sucked in from the gap on the right side of the inverter body 2 through the fan 3 on the right side, and the air is discharged from the gap on the left side of the inverter body 2 through the fan 3 on the left side, thereby dissipating the heat generated inside the inverter body 2 during operation and dissipating the heat inside the inverter body 2.

[0036] When encountering severe weather with ice and snow, first control the circulation pump 102 to pump all the cooling water in the heat pipe 101 into the bottom box 1 to ensure that there is no liquid in the heat pipe 101. Then, control the electric push rod I 107 to contract and drive the two U-shaped plates 103 to move toward each other on the inverter body 2 until the U-shaped plate 103 on the left is attached to the left side of the inverter body 2. Since the U-shaped plate 103 on the right is narrower than the U-shaped plate 103 on the left, under the same resilience of the elastic fabric 104, there is a gap between the U-shaped plate 103 on the right and the right side of the inverter body 2, such as Figure 5 As shown, the contact between the inverter body 2 and the low-temperature external air is reduced, and the inverter body 2 is protected. The fan 3 on the right side continues to draw part of the external air from the right side of the inverter body 2 into the inverter body 2. After the external air passes through the inverter body 2, the heat is taken away. At this time, the fan 3 on the left side blows out hot air.

[0037] Next, the circulation pump 102 is controlled to be closed, and the electronically controlled three-way valve 105 is controlled to be opened, so that the heat dissipation pipe 101 is connected only with the connecting pipe 106 and the circular pipe 109. At this time, the hot air blown out by the fan 3 on the left can only enter the connecting pipe 106 from the limiting groove 2a, and enter the heat dissipation pipe 101 from the connecting pipe 106, and finally come out from the connecting pipe 106 on the right, so that the hot air generated by heat dissipation circulates in the heat dissipation pipe 101, thereby keeping the heat dissipation pipe 101 warm, avoiding the cooling water in the heat dissipation pipe 101 from being frozen at an extremely low temperature, thereby damaging the heat dissipation pipe 101 and affecting the service life of the heat dissipation pipe 101.

[0038] Since ice forms on the side of the inverter body 2 under low temperature, the ice will penetrate into the inverter body 2 after melting, which is inconvenient to clean manually. Therefore, after the hot air blown out by the fan 3 on the left side enters the connecting pipe 106, a part of the hot air is blown out from the circular pipe 109 to the side of the inverter body 2, and finally blown downward after passing through the one-way valve 1010, thereby melting the ice formed on the side of the inverter body 2.

[0039] During normal use, the dustproof net 1011 is used to prevent external impurities and dust from entering the elastic fabric 104. In rainy and humid weather, water vapor will be sucked into the inverter body 2 together with the external air, and the humid water vapor will damage the electronic components in the inverter body 2. Therefore, after the hot air is blown out from the left side of the inverter body 2, a part of the hot air is guided into the guide pipe 1013 through the guide plate 1012, and the hot air entering the guide pipe 1013 is finally blown out to the dustproof net 1011 on the right side, thereby drying the water vapor in the external air. In ice and snowy low temperature weather, after the U-shaped plate 103 on the left moves to the right and fits the inverter body 2, the dustproof net 1011 is folded, and the guide plate 1012 moves to the right following the U-shaped plate 103. After the guide plate 1012 contacts the inverter body 2, the inverter body 2 rotates downward to a vertical state under the action of the torsion spring, and the torsion spring is compressed.

[0040] During normal use, the elastic cloth 104 is stretched and then pulls the filter 1014 through the elastic rope 1016, so that the intervals between the multiple filters 1014 are increased, and the spring body I 1015 is stretched to improve the heat dissipation efficiency. In icy and snowy low temperature weather, the elastic cloth 104 is contracted, the elastic rope 1016 rebounds, and the filter 1014 is overlapped with each other under the action of the rebound force of the spring body I 1015, thereby further reducing the outside air from entering the inverter body 2 and keeping the inverter body 2 warm.

[0041] Example 2

[0042] On the basis of Example 1, Figure 6-7As shown, it also includes a wedge block 201, a collecting tube 202, a spring rod I 203, a fixed tube 204 and a cover plate 206; the bottom box 1 is slidably connected to the inverter body 2; the protective box is provided in the bottom box 1 and a plurality of circular holes 1a are provided; two wedge blocks 201 are slidably connected in the bottom box 1; each wedge block 201 is fixedly connected to a plurality of collecting tubes 202, and the collecting tubes 202 correspond to the circular holes 1a; each wedge block 201 is fixedly connected to two spring rods I 203, and the spring rods I 203 are fixedly connected to the bottom box 1; each wedge block 201 is fixedly connected to a plurality of fixed tubes 204, and the fixed tubes 204 are connected to the corresponding collecting tubes 202; each collecting tube 202 is connected to a cover plate 206.

[0043] A sealing ring is provided on the inner side of the cover plate 206 to prevent water in the collecting pipe 202 from overflowing from the cover plate 206 .

[0044] The cover plate 206 is sleeved on the end of the collecting pipe 202, so that the cover plate 206 is flush with the collecting pipe 202, which facilitates the collecting pipe 202 to enter the soil.

[0045] During normal use in a high-temperature environment in summer, the bottom box 1 is placed in the dug pit, and the inverter body 2 slides downward on the bottom box 1 under the action of its own gravity, and then the inverter body 2 squeezes the wedge block 201, so that the wedge block 201 drives the collecting pipe 202 and the cover plate 206 to move away from each other in the bottom box 1, and the spring rod I 203 is compressed, so that the collecting pipe 202 and the cover plate 206 pass through the circular hole 1a and are inserted into the soil, thereby enhancing the fixing effect on the bottom box 1. Cooling water can be added to the bottom box 1 regularly to ensure that there is sufficient cooling water in the bottom box 1 to participate in the heat dissipation cycle of the heat pipe 101.

[0046] Example 3

[0047] On the basis of Example 2, Figure 6 As shown, it also includes a spring rod II 207, a spring plate 209, a spring body II 2010, an electric push rod II 2011, an extrusion block 2012 and an elastic cloth 2013; the bottom box 1 is provided with a V-shaped portion 1B; the cover plate 206 is slidably connected to the collecting tube 202; each fixed tube 204 is fixedly connected with a spring rod II 207, and the telescopic end of the spring rod II 207 is fixedly connected to the cover plate 206; the bottom box 1 is slidably connected with two spring plates 209; a plurality of spring bodies II 2010 are fixedly connected between the two spring plates 209; the inverter body 2 is bolted with an electric push rod II 2011; the telescopic end of the electric push rod II 2011 is fixedly connected with an extrusion block 2012; the bottom box 1 is fixedly connected with an elastic cloth 2013, and the extrusion block 2012 extrude the spring plate 209 through the elastic cloth 2013.

[0048] The elastic cloth 2013 is made of heat-insulating material to prevent the cooling water in the bottom box 1 from exchanging heat with the external hot air, thereby reducing the cooling efficiency of the cooling water.

[0049] Initially, there is a gap between the telescopic end of the spring plate 209 and the V-shaped portion 1B, which facilitates the circulation of cooling water in the bottom box 1. When it is cold and snowy, the electric push rod II 2011 is controlled to move the extrusion block 2012 downward. After the extrusion block 2012 contacts the elastic cloth 2013, the elastic cloth 2013 undergoes adaptive deformation, and the extrusion block 2012 continues to move downward to squeeze the spring plate 209, so that the two spring plates 209 slide back to back in the bottom box 1, and the spring body II 2010 is stretched. After the telescopic end of the spring plate 209 contacts the V-shaped portion 1B, it moves along the inclined surface of the V-shaped portion 1B, and the telescopic end of the spring plate 209 When compressed, the spring plate 209 moves along the inclined surface of the V-shaped portion 1B to squeeze the cooling water in the bottom box 1, and squeeze the cooling water into the fixed pipe 204. Then, the cooling water passes through the fixed pipe 204 and the collecting pipe 202 and pushes the cover plate 206, so that the cover plate 206 slides outward on the collecting pipe 202, thereby forming a gap between the cover plate 206 and the collecting pipe 202, and finally the cooling water enters the soil from the gap between the cover plate 206 and the collecting pipe 202, and then the cooling water is frozen in the soil on both sides of the bottom box 1, thereby enhancing the fixing effect of the bottom box 1 and the soil and resisting the wind force of the blizzard.
