Description

Technical Field

[0001] This invention relates to the field of inverter technology, and more particularly to an energy storage inverter. Background Technology

[0002] Energy storage inverters are the core conversion devices in new energy storage systems, responsible for converting the direct current (DC) stored in batteries into alternating current (AC). They integrate numerous electronic components and metal connectors, and their operational stability directly determines the power supply reliability of the energy storage system. When the inverter is operating, its core components generate heat, requiring a cooling structure to maintain a stable internal temperature. However, when shut down, the lower internal temperature can create negative pressure, allowing humid air from outside to enter the device.

[0003] Traditional energy storage inverters typically circulate heat dissipation air only within the internal core component area, lacking a targeted airflow guidance design at the bottom, which is often a sealed structure. When humid air enters, the moisture sinks to the bottom due to gravity and condenses into water. This condensate and moisture cannot be discharged in time, and long-term accumulation at the bottom can cause corrosion of metal parts, decreased insulation performance, and even short circuits, seriously affecting the service life and operational safety of the energy storage inverter. To solve the above problems, this application proposes an energy storage inverter. Summary of the Invention

[0006] As a further optimization of the present invention, the conversion mechanism includes: a support frame, which is fixedly installed inside the heat dissipation pipe and has a screw threadedly installed on it, which is fixedly connected to the sealing plate; and a winding disc, which is fixedly installed at the bottom end of the screw.

[0007] As a further optimization of the present invention, a sealing mechanism is also included, comprising: a sealing plate, which is slidably connected to the inner wall of the housing and is used to seal the drain hole; a pull rope, which passes through the first connecting pipe, with one end fixedly connected to the sealing plate and the other end fixedly connected to the winding reel; a mounting cover, which is fixedly mounted on the sealing plate; and a fixing block, which is fixedly mounted on the first connecting pipe and connected to the mounting cover by a first spring.

[0008] As a further optimization of the present invention, a cleaning mechanism is also included, the cleaning mechanism comprising: a second connecting pipe, fixedly installed on the first connecting pipe; and a rotating pipe, one end of which is rotatably connected to the second connecting pipe, and the other end of which is rotatably installed with a third connecting pipe.

[0009] As a further optimization of the present invention, the cleaning mechanism further includes: a connecting cover, which is fixedly installed on the rotating tube and has two first positioning plates fixedly installed on it; a second positioning plate, which is fixedly installed on the third connecting tube and has a third rotating shaft fixedly installed on it and rotatably connected to the first positioning plate; and a torsion spring, which is sleeved on the third rotating shaft, with one end fixedly connected to the first positioning plate and the other end fixedly connected to the second positioning plate.

[0010] As a further optimization of the present invention, it also includes an extrusion mechanism, which includes: a first rotating shaft rotatably mounted on the first connecting pipe, on which a first pulley is fixedly mounted; a fixed seat fixedly mounted on the first connecting pipe, on which a second rotating shaft is rotatably mounted; a second pulley fixedly mounted on the second rotating shaft and connected to the first pulley via a drive belt; and an inclined column fixedly mounted on the second rotating shaft.

[0011] As a further optimization of the present invention, the extrusion mechanism further includes: a first gear, which is fixedly mounted on the first rotating shaft; the sealing mechanism further includes: a rack, which is fixedly mounted on the mounting cover and meshes with the first gear.

[0012] As a further optimization of the present invention, a swing mechanism is also included, the swing mechanism comprising: a slide rod, fixedly mounted on the fixed base, on which a movable plate is slidably mounted; and a second spring, sleeved on the slide rod, one end of which is fixedly connected to the fixed base and the other end of which is fixedly connected to the movable plate.

[0014] As a further optimization of the present invention, the swing mechanism further includes: a second screw, which is rotatably mounted on the movable plate and threadedly connected to the gear frame.

[0015] The above-described technical solution of the present invention has the following beneficial technical effects:

[0016] 1. This invention controls the movement of the sealing disc to switch the airflow path inside the housing. During normal operation, the airflow circulation dissipates heat from the core components. During dehumidification, the airflow is guided to the bottom through the first connecting pipe. With the help of the inclined base, the condensate and moisture are guided to the four corner drain holes for discharge. This solves the problem of moisture accumulation caused by the bottom sealing of the inverter and avoids corrosion of metal parts and degradation of insulation performance.

[0017] 2. The cleaning mechanism of the present invention uses a torsion spring to bend the third connecting pipe to fit the inclined base, allowing the airflow to flow along the inclined surface to improve the dehumidification efficiency. The squeezing mechanism drives the inclined column to rotate, and the swing mechanism drives the third connecting pipe to rotate in both directions. The airflow is sprayed to form a fan-shaped coverage area, which can more thoroughly clean all parts of the bottom. In addition, the hot air sprayed by the third connecting pipe can neutralize the moisture, further improving the cleaning effect of condensate and moisture.

[0018] 3. The present invention can adjust the position of the gear frame by rotating the second screw, so that the gear frame is disengaged from the second gear, and the spray direction of the third connecting pipe can be manually adjusted to specifically treat the high humidity area at the bottom. After adjustment, the gear frame can be reset to restore automatic swing purging. At the same time, the guiding effect of the tilted base allows the condensate to flow to the drain hole in a concentrated manner, reducing residue. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0033] like Figures 1 to 12 As shown, the present invention proposes an energy storage inverter, comprising: a placement mechanism 110, a sealing mechanism 120, a conversion mechanism 130, a squeezing mechanism 140, a swinging mechanism 150, and a cleaning mechanism 160; the placement mechanism 110 includes a housing 111 with a through-hole vent 113, and an inclined base 112 for guiding gas and liquid to gather at the four corners is fixedly installed at the bottom of the inner cavity of the housing 111; wherein, two vent holes 113 are opened at the gas and liquid gathering points of the inclined base 112 for discharging condensate and moisture; the conversion mechanism 130... Mechanism 130 includes a heat dissipation pipe 131 fixedly installed on housing 111, a heat dissipation fan 137 providing airflow power fixedly installed at the bottom of heat dissipation pipe 131, a sealing plate 133 provided at the top of heat dissipation pipe 131, and first connecting pipes 132 extending to the bottom of the inner cavity of housing 111 fixedly installed on the left and right sides of heat dissipation pipe 131; wherein, by controlling the movement of sealing plate 133, the airflow path inside housing 111 is changed, so that the airflow after heat dissipation is directed to the bottom of the inner cavity of housing 111, and carries away the condensate and moisture at the bottom.

[0034] In this embodiment, in the initial state, the bottom of the housing 111 is a sealed structure. During normal operation, the airflow only circulates in the middle area of ​​the housing 111 and cannot reach the bottom of the inner cavity. When the inverter stops, the internal temperature drops, forming a negative pressure. Humid air from the outside is drawn into the housing 111. The moisture sinks under the influence of gravity and condenses at the bottom to form condensate. The sealed structure prevents the condensate and moisture from being discharged, and long-term accumulation leads to corrosion of the metal parts at the bottom of the housing 111 and a decrease in insulation performance. When dehumidification is required, the airflow path inside the housing 111 is switched by controlling the movement of the sealing plate 133. The airflow after heat dissipation is guided through the first connecting pipe 132 to the bottom of the inner cavity of the housing 111 to blow it clean. At the same time, the inclined base 112 guides the airflow and condensate to the four corners where they gather. The moisture and condensate are then discharged from the outside of the housing 111 through the drain hole 113 under the action of the airflow, allowing the bottom to be dehumidified and drained, thus preventing bottom corrosion.

[0035] like Figure 5 As shown, the conversion mechanism 130 includes a heat dissipation pipe 131, a first connecting pipe 132, a sealing plate 133, a screw 134, a support frame 135, a winding reel 136, and a cooling fan 137; the support frame 135 is fixedly installed inside the heat dissipation pipe 131, and the screw 134, which is fixedly connected to the sealing plate 133, is threaded onto the support frame 135; the winding reel 136 is fixedly installed at the bottom end of the screw 134.

[0036] In this embodiment, the sealing plate 133 has a hexagonal groove on its top, which is convenient to insert with a hexagonal wrench. The sealing plate 133 rotates, which in turn drives the screw 134 to rotate. As a result, the sealing plate 133 moves downward and enters the heat dissipation pipe 131, thus sealing the top of the heat dissipation pipe 131. In this way, the airflow drawn from the inside of the housing 111 by the cooling fan 137 enters the heat dissipation pipe 131 and cannot be discharged. Instead, it enters the first connecting pipe 132. Since the first connecting pipe 132 is a one-way pipe, air can only enter from the heat dissipation pipe 131 and exit from the bottom of the inner cavity of the housing 111. Thus, when the sealing plate 133 is not sealing, the gas in the upper part of the housing 111 circulates normally, dissipating the heat emitted from the core components. When it is necessary to clean moisture and condensate, the gas circulation path can be changed, and the airflow can be used to clean the moisture and condensate.

[0037] like Figure 5 and Figure 6 As shown, the sealing mechanism 120 includes a sealing plate 121, a pull rope 122, a first spring 123, a mounting cover 124, a rack 125, and a fixing block 126. The sealing plate 121 is slidably connected to the inner wall of the housing 111 and is used to seal the drain hole 113. The pull rope 122 passes through the first connecting pipe 132, with one end of the pull rope 122 fixedly connected to the sealing plate 121 and the other end of the pull rope 122 fixedly connected to the winding reel 136. The mounting cover 124 is fixedly installed on the sealing plate 121. The fixing block 126 is fixedly installed on the first connecting pipe 132 and is connected to the mounting cover 124 through the first spring 123.

[0038] In this embodiment, when the winding reel 136 starts to rotate, the winding reel 136 will wind the pull rope 122. The pull rope 122 being wound will pull the sealing plate 121 upward, so that the sealing plate 121 will move out of the drain hole 113, opening the drain hole 113. When the drain hole 113 is open, the accumulated condensate will be discharged from the drain hole 113 in conjunction with the inclined base 112. When the winding reel 136 reverses and releases the pull rope 122, the first spring 123 will cause the sealing plate 121 to return to its original position and continue to seal the drain hole 113, ensuring the seal of the bottom of the housing 111.

[0039] like Figure 8 , Figure 10 and Figure 11 As shown, the cleaning mechanism 160 includes a second connecting pipe 161, a rotating pipe 162, a second gear 163, a connecting cover 164, a third connecting pipe 165, a first positioning plate 166, a second positioning plate 167, a torsion spring 168, and a third rotating shaft 169.

[0040] The second connecting pipe 161 is fixedly installed on the first connecting pipe 132; one end of the rotating pipe 162 is rotatably connected to the second connecting pipe 161, and the other end of the rotating pipe 162 is rotatably installed with a third connecting pipe 165; the connecting cover 164 is fixedly installed on the rotating pipe 162, and two first positioning plates 166 are fixedly installed on the connecting cover 164; the second positioning plate 167 is fixedly installed on the third connecting pipe 165, and a third rotating shaft 169 rotatably connected to the first positioning plate 166 is fixedly installed on the second positioning plate 167; the torsion spring 168 is sleeved on the third rotating shaft 169, one end of the torsion spring 168 is fixedly connected to the first positioning plate 166, and the other end of the torsion spring 168 is fixedly connected to the second positioning plate 167.

[0041] In this embodiment, the end of the third connecting pipe 165 near the rotating pipe 162 is a rigid pipe, while the rest is a flexible pipe. Therefore, the third connecting pipe 165 can be bent. When the gas drawn by the cooling fan 137 is delivered into the first connecting pipe 132, the gas will enter the second connecting pipe 161 through the first connecting pipe 132, and then enter the third connecting pipe 165 through the rotating pipe 162. Finally, it will be discharged from the third connecting pipe 165. Since a torsion spring 168 is provided at the third connecting pipe 165, the torsion spring 168 can bend one end of the third connecting pipe 165 to fit the inclined surface of the inclined base 112. In this way, the gas ejected from the third connecting pipe 165 can flow along the inclined surface of the inclined base 112, which helps to guide the airflow along the inclined surface and improve the dehumidification effect.

[0042] In this embodiment, as Figures 6 to 11 As shown, the extrusion mechanism 140 includes a second rotating shaft 141, a drive belt 142, a first pulley 143, a first gear 144, a first rotating shaft 145, an inclined column 146, a fixed seat 147, and a second pulley 148. The first rotating shaft 145 is rotatably mounted on the first connecting pipe 132, and the first pulley 143 is fixedly mounted on the first rotating shaft 145. The fixed seat 147 is fixedly mounted on the first connecting pipe 132, and the second rotating shaft 141 is rotatably mounted on the fixed seat 147. The second pulley 148 is fixedly mounted on the second rotating shaft 141 and is connected to the first pulley 143 via the drive belt 142. The inclined column 146 is fixedly mounted on the second rotating shaft 141. The first gear 144 is fixedly mounted on the first rotating shaft 145. The rack 125 is fixedly mounted on the mounting cover 124 and meshes with the first gear 144.

[0043] In this embodiment, when the mounting cover 124 begins to move upward, the mounting cover 124 will drive the rack 125 to move upward. The upward movement of the rack 125 will drive the first gear 144 to rotate. The rotation of the first gear 144 will cause the first rotating shaft 145 to drive the first pulley 143 to rotate. The rotation of the first pulley 143 will cause the second pulley 148 to rotate through the drive belt 142. The rotation of the second pulley 148 will cause the second rotating shaft 141 to rotate. The rotation of the second rotating shaft 141 will drive the inclined column 146 to rotate.

[0044] like Figure 10 and Figure 12 As shown, the swing mechanism 150 includes a second spring 151, a moving plate 152, a slide bar 153, a pressing column 154, a second screw 155, and a gear frame 156;

[0045] A slide rod 153 is fixedly mounted on a fixed base 147, and a movable plate 152 is slidably mounted on the slide rod 153; a second spring 151 is sleeved on the slide rod 153, one end of the second spring 151 is fixedly connected to the fixed base 147, and the other end of the second spring 151 is fixedly connected to the movable plate 152; a pressing column 154 is fixedly mounted on the movable plate 152; a gear frame 156 is slidably mounted on the movable plate 152; a second gear 163 is fixedly mounted on a rotating tube 162, and the second gear 163 meshes with the gear frame 156; a second screw 155 is rotatably mounted on the movable plate 152, and the second screw 155 is threadedly connected to the gear frame 156.

[0046] In this embodiment, when the second rotating shaft 141 starts to rotate, the second rotating shaft 141 will drive the inclined column 146 to rotate. As the inclined column 146 rotates, the inclined column 146, in conjunction with the second spring 151, will cause the extrusion column 154 to move left and right continuously. The left and right movement of the extrusion column 154 will drive the gear frame 156 to move left and right. In this way, the gear frame 156 will cause the second gear 163 to rotate in both directions. The rotation of the second gear 163 in both directions will drive the third connecting pipe 165 to rotate in both directions. In this way, the gas ejected from the third connecting pipe 165 will form a fan-shaped area, which can act on all parts of the drain hole 113, and can better clean up residual moisture and condensate. Moreover, the gas ejected from the third connecting pipe 165 is hot gas, which can neutralize the moisture, making it more conducive to removing moisture.

[0047] Furthermore, by rotating the second screw 155, the gear frame 156 can be moved up and down, which allows the gear frame 156 to disengage from the second gear 163. Then, by rotating the second gear 163, the third connecting pipe 165 is aligned with the other half, and the gear frame 156 is controlled to return to its original position. In this way, when the gear frame 156 moves left and right, the third connecting pipe 165 can clean the moisture on the other half. If the moisture concentration is high, a small amount of condensate may be formed when the hot air blows. The spray direction of the two third connecting pipes 165 can be adjusted to be consistent, so that the condensate flows in the same direction and is easy to be discharged from the drain hole 113.

[0048] Working principle: When the energy storage inverter is working, the core components generate heat, which starts the cooling fan 137 of the conversion mechanism 130. At this time, the sealing plate 133 does not seal the top of the heat dissipation pipe 131, and the airflow circulates in the upper part of the housing 111, carrying away the heat of the core components and achieving conventional heat dissipation.

[0049] When the inverter stops, the internal temperature drops, creating negative pressure. Humid air from the outside enters the casing 111, and the moisture sinks to the bottom and condenses into water. The dehumidification mode needs to be activated: the sealing plate 133 is rotated by a tool, which drives the screw 134 to rotate and move downward. The sealing plate 133 enters the heat sink 131 and blocks the airflow channel at the top. The airflow drawn by the cooling fan 137 cannot be discharged from the top and is guided to the bottom of the inner cavity of the casing 111 through the first connecting pipe 132. The rotation of the screw 134 drives the winding disc 136 to rotate, winding the pull rope 122. The pull rope 122 pulls the sealing plate 121 upward, disengaging it from the drain hole 113 and opening the drainage channel. The mounting cover 124 moves synchronously with the sealing plate 121, compressing the first spring 123.

[0050] When the mounting cover 124 moves upward, the rack 125 meshes with the first gear 144, driving the first rotating shaft 145 and the first pulley 143 to rotate; the first pulley 143 drives the second pulley 148 through the drive belt 142, driving the second rotating shaft 141 and the inclined column 146 to rotate.

[0051] The tilting column 146 rotates and squeezes the squeezing column 154. With the restoring force of the second spring 151, the moving plate 152 drives the gear frame 156 to move back and forth. The gear frame 156 meshes with the second gear 163, driving the rotating tube 162 and the third connecting tube 165 to swing in both directions.

[0052] Under the action of the torsion spring 168, the third connecting pipe 165 bends and fits the inclined surface of the inclined base 112; the airflow is sprayed through the third connecting pipe 165 to form a fan-shaped coverage area, sweeping all parts of the bottom, and cooperating with the inclined base 112 to guide the condensate and moisture to the drain hole 113 for discharge.

[0053] After dehumidification is completed, the sealing disc 133 is rotated in the opposite direction, and the screw 134 drives the sealing disc 133 to move upward and reset, and the winding disc 136 releases the pull rope 122; the first spring 123 resets and pushes the sealing plate 121 downward to re-seal the drain hole 113; each transmission component moves in the opposite direction, the third connecting pipe 165 stops swinging, and the heat dissipation airflow resumes its normal circulation path.

[0054] If a high-humidity area needs to be treated specifically, the second screw 155 can be rotated, the position of the gear 156 can be adjusted so that it disengages from the second gear 163, the spray direction of the third connecting pipe 165 can be manually adjusted, and the automatic oscillation can be restored by resetting the gear 156 after adjustment.

[0055] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
