Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage frequency converters for water pumps, specifically a high-voltage frequency converter for condensate pumps that is easy to assemble. Background Technology

[0002] High-voltage frequency converters for condensate pumps that are easy to assemble are a common type of equipment. They typically employ a modular design, where each functional unit of the frequency converter, such as the power unit, control unit, and filter unit, is designed as an independent module. These modules are connected to each other through standardized interfaces and connectors.

[0003] Currently, common condensate pumps typically have a base installed on the wiring connector using bolts and threads, with threaded holes around the base. The high-voltage frequency converter is then installed on this base via bolt thread connections. However, high-voltage frequency converters are high-precision devices and are prone to malfunctions under various influences during use, requiring disassembly for repair. Since the high-voltage frequency converter is installed on the base via bolt thread connections, workers must use screwdrivers and other tools to unscrew each bolt individually, making the process cumbersome and inefficient. Furthermore, while the high-voltage frequency converter is easy to assemble, during water transportation, the surrounding environment is often humid, and the bolts are not isolated from moisture, making them susceptible to rust, reducing their lifespan and increasing the difficulty of subsequent disassembly, thus affecting the normal disassembly and assembly of the high-voltage frequency converter.

The middle part of the base is provided with a sliding hole, and a plug rod is slidably disposed in the sliding hole. The middle part of the sliding plate is correspondingly provided with a plug hole. When the sliding plate slides along the sliding groove to a preset position, the plug rod can be inserted into the plug hole, thereby fixing the sliding plate and the high-voltage frequency converter to the base.

[0008] Furthermore, the base includes a base plate, a sliding hole is formed in the middle of the base plate, a connecting plate is provided on the upper part of the base plate, and a sliding groove is formed on the connecting plate.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a high-pressure frequency converter for condensate pumps that is easy to assemble, and has the following beneficial effects:

[0016] This easy-to-assemble condensate pump high-voltage frequency converter can be installed by having the operator pull the plug rod downwards to disengage it from the slot on the slide plate. The slide plate can then be removed from the groove, and the high-voltage frequency converter can be disassembled. Releasing the fingers allows the spring to contract, enabling the plug rod to be pulled upwards and inserted into the slot on the slide plate for installation. Next, by sliding the top plate within the slot, the hole is sealed, effectively sealing the plug rod and other components internally and isolating them from external moisture. This improves sealing, reduces the likelihood of rust on the plug rod and other components, and simplifies disassembly, thus achieving the goal of easy disassembly. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-2 This utility model discloses an easy-to-assemble high-voltage frequency converter for a condensate pump, comprising a condensate pump 1 and a high-voltage frequency converter 2. The top of the condensate pump 1 is provided with a wire connector 3. Several threaded holes are evenly distributed around the outer periphery of the wire connector 3, and each threaded hole is threaded with a bolt. The bolts are threadedly connected to the base, and the base is mounted on the wire connector 3 through the threaded connection of the bolts and threaded holes. A sliding groove 4 is provided on the upper part of the base, and a sliding plate 5 is slidably connected within the sliding groove 4. The cross-section of the sliding groove 4 is cross-shaped to prevent the sliding plate 5 from sliding off the groove 4. Slide upwards to disengage from the slide groove 4. The upper surface of the slide plate 5 is fixedly connected to the bottom of the high-voltage frequency converter 2. Through the sliding arrangement of the slide plate 5 and the slide groove 4, the high-voltage frequency converter 2 is initially installed on the base. A sliding hole is opened in the middle of the base, and a plug-in rod 6 is slidably arranged in the sliding hole. A corresponding plug hole 7 is opened in the middle of the slide plate 5. When the slide plate 5 slides along the slide groove 4 to the preset position, the plug-in rod 6 can be inserted into the plug hole 7, thereby fixing the slide plate 5 and the high-voltage frequency converter 2 on the base. At this time, the high-voltage frequency converter 2 is fixed. The installation operation steps are simple and improve the ease of assembly.

[0027] The base includes a base plate 8, a sliding hole is opened in the middle of the base plate 8, a connecting plate 9 is provided on the upper part of the base plate 8, and a sliding groove 4 is opened on the connecting plate 9.

[0028] The sliding hole includes a hole body 10, which penetrates the upper part of the base plate 8. The insertion rod 6 slides within the hole body 10. A hole body 2 11 is provided at the lower part of the hole body 10, which penetrates the lower part of the base plate 8. A limit block 12 is provided at the lower part of the insertion rod 6, which slides within the hole body 2 11. A spring 13 is fixedly provided at the upper part of the limit block 12. The upper part of the spring 13 is fixedly provided with the top of the hole body 2 11. The spring 13 provides an upward pulling force to the limit block 12, causing the limit block 12 to slide upward into the housing 2. At the top, push the plug rod 6 upward to slide within the hole 10, then slide out and enter the sliding hole of the bottom plate 8 to fix the slide plate 5. The lower part of the limiting block 12 is provided with an extension plate 14. The operator pinches the extension plate 14 and pulls it downward, causing the limiting block 12 and the plug rod 6 to slide downward, stretching the spring 13. When the upper part of the plug rod 6 disengages from the plug hole 7 of the slide plate 5 and enters the hole 10, the slide plate 5 can be slid out of the sliding groove 4 of the connecting plate 9 for disassembly.

Then, the extension plate 14 is pinched and pulled downwards, extending the spring 13 and causing the head of the insertion rod to slide into the hole 10. Next, the high-voltage frequency converter 2 is picked up, and the sliding plate 5 is aligned with the groove 4 of the connecting plate 9, then slid into the groove 4. Once fully inserted into the groove 4... When it reaches the side wall of the slide groove 4, it stops moving. At this time, the insertion hole 7 of the slide plate 5 and the hole body 10 are aligned. Then, the extension plate 14 is released, the spring 13 contracts, and provides an upward pulling force to the limiting block 12, causing the limiting block 12 to slide upward to the upper part of the housing 2. This pushes the insertion rod 6 to move upward, slide in the hole body 10, and then slide out into the sliding hole of the bottom plate 8 to fix the slide plate 5. After that, the sealing plate 16 is pulled to slide in the slot 15 until the hole body 2 11 is sealed.
