Description

Technical Field

[0001] This application relates to the field of inverter testing technology, and in particular to an outdoor energy storage inverter airtightness testing fixture and testing line. Background Technology

[0002] An energy storage inverter is a comprehensive device that combines an inverter and an energy storage system. It can be used to convert electrical energy into another form and store it in batteries to cope with power fluctuations, improve grid stability, and provide convenient power support for renewable energy and daily life and travel.

[0003] Outdoor energy storage inverters, as the name suggests, are energy storage inverters installed or fixed in outdoor environments. Because outdoor energy storage inverters are highly reliable devices used outdoors, their waterproof performance must be guaranteed. Therefore, during the production process, the waterproof performance of outdoor energy storage inverters needs to be tested. This is typically done through an airtightness test, which achieves the desired waterproofing effect while being fast and efficient.

[0004] Knockout holes are often made on the casing of outdoor energy storage inverters to facilitate pipe installation by users. However, during the manufacturing process, these knockout holes can allow air to pass through, affecting the effectiveness and efficiency of airtightness testing. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0037] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of some known functions and components have been omitted.

[0038] This disclosure provides an outdoor energy storage inverter airtightness testing fixture, including:

[0039] A sealing structure is used to abut against the outdoor energy storage inverter and to airtightly seal the knockout hole of the outdoor energy storage inverter.

[0040] The airtight seal is controllable.

[0041] The airtightness testing of outdoor energy storage inverters is typically conducted in an assembly line manner. The airtightness of outdoor energy storage inverters needs to be controllable, meaning the airtightness sealing process must be completed and maintained quickly. In the design, the outer casing of the outdoor energy storage inverter is airtight, with only the knockout hole allowing ventilation.

[0042] Therefore, during operation, the sealing structure abuts against the outdoor energy storage inverter, cooperating with the inverter's outer casing to form an airtight sealing space outside the knockout hole, thus providing an airtight seal for the outdoor energy storage inverter. When the sealing structure disengages, this airtight sealing space is released.

[0043] As one optional embodiment, the sealing structure is a movable structure;

[0044] The movable structural component is movably connected to the outdoor energy storage inverter, and when connected, it provides an airtight seal to the knockout hole of the outdoor energy storage inverter; when disconnected, the airtight seal is released.

[0045] The movable contact of the sealing structure can be based on the outdoor energy storage inverter or the assembly line base.

[0046] As one optional embodiment, the outdoor energy storage inverter airtightness test fixture of a disclosed embodiment further includes:

[0047] A power unit is used to provide a power source for the movable structural member.

[0048] The power unit is used to enable the movable structural components to perform corresponding controllable movements, such as engaging or disengaging from the outdoor energy storage inverter. The power unit can be a pushing device, a rotating device, etc., and can be adaptively adjusted according to the structural characteristics of the movable structural components.

[0049] As one optional embodiment, the sealing structure is an adhesive structure;

[0050] The adhesive structural component is used to abut against the outdoor energy storage inverter by adhesive bonding, and to airtightly seal the knockout hole of the outdoor energy storage inverter.

[0051] Unlike movable structural components, adhesive structural components are bonded to the outdoor energy storage inverter by adhesive bonding and the bonding is removed by detaching the adhesive.

[0052] As a preferred embodiment, taking the sealing structure as a movable structure, and the movable structure cooperating with the outer casing of the outdoor energy storage inverter to form an airtight sealed space outside the knockout hole as an example, a schematic diagram of the airtightness test fixture structure for an outdoor energy storage inverter of a preferred embodiment is provided, as follows. Figure 1 As shown.

[0053] like Figure 1 As shown, the sealing structure includes:

[0054] A sealed housing with one side open;

[0055] A sealing strip 1 is provided at the edge of the opening on the open surface of the sealing housing 3;

[0056] The open surface is used to abut against the outdoor energy storage inverter, and a sealed space is formed between the sealed housing 3 and the outdoor energy storage inverter to airtightly seal the knockout hole of the outdoor energy storage inverter.

[0057] Among them, the sealing strip 1 abuts against the outdoor energy storage inverter to ensure the airtightness of the sealed space formed by the sealing shell 3 and the outdoor energy storage inverter.

[0058] like Figure 1 As shown, the sealing housing includes:

[0059] Base plate 4;

[0060] Side plates 2 are set around the base plate.

[0061] The base plate 4 and the side plate 2 together form a sealed housing 3, and an open surface is formed on the opposite side of the base plate 4 that contacts the outdoor energy storage inverter.

[0062] As a preferred embodiment, such as Figure 1 As shown, the power unit includes:

[0063] Push rod 8 used to push the movable structural member to move;

[0064] A push rod pushing device is used to provide pushing power for the push rod 8.

[0065] like Figure 1 As shown, the sealing housing 3 is pushed by the push rod 8 to bring it into contact with the outdoor energy storage inverter. Alternatively, the sealing housing 3 is retracted by the push rod 8 to disengage it from the outdoor energy storage inverter.

[0066] The push rod actuation device includes a cylinder or a motor. Preferably, such as... Figure 1 As shown, the push rod pushing device uses a cylinder (5 or 6) to push the push rod 8 or retract the push rod 8.

[0067] As one of the optional embodiments, the power unit is fixedly mounted on the assembly line base, which indirectly achieves the same purpose as fixing the sealing structure on the assembly line base. In this case, the airtightness test of the outdoor energy storage inverter can be carried out in the form of an assembly line.

[0068] The outdoor energy storage inverter airtightness testing fixture of any embodiment of this disclosure includes a sealing structure for abutting against the outdoor energy storage inverter and airtightly sealing the knockout hole of the outdoor energy storage inverter; wherein, the airtightness seal is controllable. Therefore, in the airtightness testing of the outdoor energy storage inverter, since the knockout hole is airtightly sealed, air can be directly injected into the outdoor energy storage inverter for airtightness testing, ensuring the effectiveness of the airtightness test. Simultaneously, because the airtightness seal is controllable, the airtightness sealing can be quickly terminated, ending the airtightness testing operation and improving the stability and efficiency of the airtightness testing operation.

[0069] Based on any embodiment of the outdoor energy storage inverter airtightness testing fixture of this disclosure, this disclosure also provides a testing pipeline, including:

[0070] Assembly line base;

[0071] An outdoor energy storage inverter airtightness testing fixture, as described in any of the above embodiments, is used for operations based on the assembly line base.

[0072] like Figure 2As shown, the outdoor energy storage inverter moves relative to the outdoor energy storage inverter airtightness test fixture in direction X. When the knockout hole 7 moves into the working range of the outdoor energy storage inverter airtightness test fixture, a sealed space is formed between the outdoor energy storage inverter airtightness test fixture and the outdoor energy storage inverter. After the air source fills the outdoor energy storage inverter with air, there is no air leakage problem in other parts of the outdoor energy storage inverter. At this time, the air inside the outdoor energy storage inverter will leak out through the knockout hole 7 at the bottom of the outdoor energy storage inverter. Since the outdoor energy storage inverter airtightness test fixture and the bottom of the outdoor energy storage inverter are tightly fitted and form a sealed space, becoming an integral part of the outdoor energy storage inverter, the air source filling the outdoor energy storage inverter will not leak out.

[0073] The test pipeline of this disclosure includes a pipeline base and an outdoor energy storage inverter airtightness testing fixture that operates based on the pipeline base. The outdoor energy storage inverter airtightness testing fixture includes a sealing structure for abutting against the outdoor energy storage inverter and airtightly sealing the knockout hole of the outdoor energy storage inverter; wherein, the airtightness seal is controllable. Therefore, in the airtightness testing of the outdoor energy storage inverter, since the knockout hole is airtightly sealed, air can be directly injected into the outdoor energy storage inverter for airtightness testing, ensuring the effectiveness of the airtightness test. Simultaneously, because the airtightness seal is controllable, the airtightness sealing can be quickly terminated, ending the airtightness testing operation, thus improving the stability and efficiency of the airtightness testing operation.
