Description

Technical Field

[0001] The utility model belongs to the technical field of liquid-cooled charging piles, and in particular relates to automated liquid-cooled charging pile testing equipment. Background Art

[0002] Existing liquid-cooled charging pile products have a large number of liquid-cooling pipeline connections due to the need to connect the liquid-cooling heat dissipation system with the external charging gun and the entire system as well as the connection requirements for its own pipeline operation. When the liquid-cooled charging pile product is running, the internal coolant or cooling oil needs to be used to dissipate the heat of the liquid-cooled charging gun line through the pipeline. Since the liquid-cooled charging gun cable is long and the heat dissipation pipeline diameter is small after the cable is lightweight, the operating pressure in the pipeline is relatively high. To ensure that the product equipment does not cause leakage or other faults due to insufficient pipeline sealing when working, the current solution adopted in the industry is to only test the airtightness of the liquid-cooling heat dissipation system unit separately, and perform an aging test process separately after passing the test. The whole machine is then assembled together and shipped directly.

[0003] The existing technical solutions only test one or two steps in the product operation separately, and cannot achieve a closed-loop test for the equipment of the entire product from processing to finished product shipment. The product reliability cannot be guaranteed. In addition, the oiling of the liquid cooling system unit and the entire machine is a manual operation. Due to the limitation of the oil tank size, the equipment needs to be manually started a second time. The amount of oil cannot be controlled, and the consistency of the product cannot be guaranteed. The oil used in the aging test cannot be replaced before shipment. Since there may be impurities in the oil tank and pipelines, long-term use may easily cause pipeline blockage and reduce life. At the same time, it is easy to cause leakage or other quality problems, and the market application risk is relatively high. Summary of the Invention

[0004] The purpose of the utility model is to provide an automated liquid-cooled charging pile testing device that can significantly reduce the risks of leakage, pipe blockage, excessive internal pressure, affecting charging current and other quality risks of current liquid-cooled charging pile equipment.

[0005] The utility model provides an automated liquid-cooled charging pile testing device, comprising: a device main body, a new oil barrel located inside and at the bottom of the device main body, an output pair of sockets and an input pair of sockets connected to the side of the device main body, and a test circulation oil tank fixed inside and located on the upper part of the device main body; wherein the output pair of sockets and the input pair of sockets are arranged in parallel and are located between the new oil barrel and the test circulation oil tank; an external liquid-cooled charging pile liquid cooling pipeline is connected to the output pair of sockets and the input pair of sockets.

[0006] Furthermore, it also includes an industrial computer located in the device body.

[0007] Furthermore, it also includes an airtightness tester, multiple function indicators and multiple function debugging knobs located in the device body.

[0008] Furthermore, it also includes a ventilation valve device, a pressure detector, a heating device and a flow tester located in the device body.

[0009] Furthermore, the ventilation valve device, pressure detector, heating device and flow tester are all located on the upper surface of the equipment body.

[0010] Furthermore, it also includes an air compressor and a water vapor filtering device.

[0011] Furthermore, it also includes a universal wheel that supports the device body and is located at the bottom of the device body.

[0012] The utility model discloses an automated liquid-cooled charging pile testing equipment, which can greatly reduce other quality risks such as leakage of current liquid-cooled charging pile equipment and excessive internal pressure caused by pipe blockage, which affects the charging current. Because fine particles such as dust, iron filings, and welding slag will exist in the product processing process, in order to avoid clogging the oil circuit, this equipment is designed with two sets of isolation protection systems for production test oil and finished product delivery oil (that is, the test equipment uses circulating oil and the product is shipped with new oil), to avoid dust, iron filings, welding slag and other fine particles in the test equipment and oil circuit from mixing into the finished product, ensuring the consistency of the product during long-term use and avoiding quality risks. In addition, the equipment meets the requirements of automatic control of the refueling volume, and the refueling volume can be set according to the size of the equipment, which increases the compatibility of use while ensuring the consistency of the refueling volume of the product.

[0014] Hereinafter, some specific embodiments of the present invention will be described in detail in an illustrative and non-limiting manner with reference to the accompanying drawings. The same reference numerals in the accompanying drawings indicate the same or similar components or parts. It should be understood by those skilled in the art that these drawings are not necessarily drawn to scale.

[0015] In the attached figure:

[0016] Figure 1 This is a schematic diagram of the structure of an automated liquid-cooled charging pile testing device according to one embodiment of the present invention;

[0017] Figure 2 This is a structural schematic diagram of the automated liquid-cooled charging pile testing equipment from another angle according to an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The utility model discloses an automated liquid-cooling charging pile testing device, which can meet the requirements of full-process automated testing of liquid-cooling charging piles.

[0019] like Figure 1 and Figure 2 As shown, the automated liquid-cooled charging pile testing equipment of the present invention includes: an equipment main body 1, a new oil barrel 2 and an air compressor 14 located in the equipment main body 1, a water vapor filtering device (not shown), a universal wheel 15 that supports the equipment main body 1 and is located at the bottom of the equipment main body 1, an output pair socket 3 and an input pair socket 4 connected to the side of the equipment main body 1, a test circulation oil tank 5 fixed on the equipment main body 1, an industrial computer 6 located in the equipment main body 1, an airtightness tester 11 located in the equipment main body 1 and arranged in parallel with the industrial computer 6, a plurality of function indicators 12, a plurality of function debugging knobs 13, a vent valve device 7, a pressure detector 8, a heating device 9 and a flow tester 10.

[0020] The new oil barrel 2 is located at the bottom of the equipment body 1, and the test circulation oil tank 5 is located at the upper part of the equipment body 1. The output socket 3 and the input socket 4 are arranged in parallel and located between the new oil barrel 2 and the test circulation oil tank 5.

[0021] The vent valve assembly 7, pressure detector 8, heating device 9, and flow meter 10 are all located on the upper surface of the main device 1. Multiple function indicators 12 display the compressor inlet pressure, compressor output pressure, and flow rate. Multiple function adjustment knobs 13 adjust the compressor inlet pressure, compressor output pressure, and flow rate.

[0022] During operation, the external liquid-cooled charging pile cooling pipes connect to the output and input sockets 3 and 4 of the automated liquid-cooled charging pile test equipment through self-sealing connectors. The interfaces meet the design requirements of self-sealing. By changing the adapters on the cooling pipes, single-gun and dual-gun testing can be achieved.

[0023] The utility model realizes a self-sealing quick-plug connection with the liquid cooling equipment end through the output socket 3 and the input socket 4, ensuring the convenience of the production operation of the entire pile test. The self-sealing property of the joint can ensure that there will be no leakage during the process of filling and drawing liquid from the entire machine pipeline.

[0024] Through the startup software of the industrial computer 6 that comes with the automated liquid-cooled charging pile test equipment of the present invention, the pressure test, test time, temperature setting and other related parameters are set. The automated liquid-cooled charging pile test equipment of the present invention supports fully automatic and semi-automatic process tests, and can also start a certain test separately, so that employees can choose to start the test item according to actual test needs.

[0025] The automated liquid-cooled charging pile testing equipment of the present invention sets the airtightness test parameters or selects the test parameters that have been preset by the system through the industrial computer interface. After the airtightness pressure test is started, the equipment's built-in air compressor 14 starts working until the pressure value set by the equipment is reached. At the same time, the water vapor filter filters the water vapor in the air pressure to ensure the dryness of the air. The equipment starts to inflate the cavity of the entire liquid cooling pipeline through the pipeline. At the same time, the function indicator is automatically started (i.e., the airtightness tester) 12 to display and monitor the test process values ​​in real time. The test results will be displayed in real time on the interface of the industrial computer 6, which is convenient for employees to confirm parameters and record and debug data.

[0026] After the aforementioned test steps pass, the automated liquid-cooled charging pile test equipment begins the second test step set by the system. The system fills the entire liquid-cooled charging pile pipeline with liquid through its built-in test circulation tank 5. During the filling process, the instantaneous flow rate and system pressure can be monitored in real time via the industrial computer 6 interface. If the system's set pressure is exceeded, an alarm will be issued via the screen or light, facilitating early assessment of any pressure blind spots in the equipment and enabling timely parameter or equipment adjustments. The automated liquid-cooled charging pile test equipment automatically fills the equipment according to the system's set oil volume, supporting single or multiple refills and compatibility with a wider range of equipment models.

[0027] After the oil filling process is completed, the automated liquid-cooled charging pile test equipment of the utility model begins the next aging test process set by the system. The pipeline first uses the flow tester 10 to detect flow-related data, and then uses the pressure tester 8 to collect pipeline pressure-related data. Finally, the oil temperature in the pipeline is raised to the set oil temperature by the adjustable heating device 9, and then transmitted to the oil inlet of the liquid-cooled charging gun, circulating cooling the liquid-cooled gun. The oil return line from the liquid-cooled charging gun then returns to the radiator for cooling, and finally returns to the test equipment circulating oil tank 5 through the pipeline, completing a round of heat dissipation cycle testing. The overall test time can be adjusted and set as needed.

[0028] After the above test process is completed, air compressor 14 starts to apply air pressure to the pipeline, blowing the circulating oil in the entire liquid cooling device cavity back into the test equipment circulating oil tank 5. At the same time, the air pressure is transmitted, and impurities, iron filings, etc. in the system pipeline are returned to the oil tank along with the oil line and fall into the oil tank filter box.

[0029] After the above steps are completed, the automated liquid-cooled charging pile test equipment automatically initiates the next step, performing a secondary airtightness test on the entire liquid-cooling equipment pipeline. The process is similar to the second step above. This ensures that the product can still meet the system's set operating pressure after long-term operation, thus ensuring product reliability.

[0030] After the secondary airtightness is achieved, the device initiates the next process set by the system. Using the new oil barrel 2 placed at the bottom of the test device body 1, the liquid-cooled charging pile pipeline is filled with new oil once or multiple times with precise values. This ensures the consistency of the product injection.

[0031] After the above steps are completed, the self-sealing connectors on the output and input sockets 3 and 4 of the liquid-cooled charging pile connected to the automated liquid-cooled charging pile test equipment of the present invention are pulled out and reset to the liquid-cooled charging pile to complete the entire test process.

[0032] The test process documents can be saved in real time according to the product code, and can be automatically uploaded to the corresponding server through the industrial computer 6 and exported in real time to meet the requirements of subsequent product quality tracking and material traceability, making product maintenance more convenient.

[0033] The entire test process is: the equipment is connected to the liquid-cooled charging pile cooling system unit pipeline; the entire liquid-cooled charging pile is tested for air tightness; circulating test oil is added; the heating device 9 is started; the aging test is started (the equipment monitors the pipeline flow, pressure, and temperature in real time); the oil in the pipeline is blown into the test circulating oil tank 5; the whole machine is tested for air tightness after the aging test; new oil is automatically added; the pipeline is inserted back into the original liquid-cooled charging pile's plug-in pipeline to complete the entire test process.

[0034] The inlet and outlet cooling pipes of the liquid-cooled charging pile are connected to the self-sealing quick-connect plugs on the liquid-cooled complete unit test equipment using self-sealing plugs, ensuring convenient testing of the entire pile and increasing personnel efficiency. The self-sealing nature of the connectors prevents leakage during the filling and extraction process, while also meeting the requirements of automated extraction and injection. By adapting the cooling pipes, single-gun and dual-gun simultaneous testing can be achieved, increasing equipment compatibility and reducing investment costs.

[0035] The utility model discloses an automated liquid-cooled charging pile testing equipment, which can greatly reduce other quality risks such as leakage of current liquid-cooled charging pile equipment and excessive internal pressure caused by pipe blockage, which affects the charging current. Because fine particles such as dust, iron filings, and welding slag will exist in the product processing process, in order to avoid clogging the oil circuit, this equipment is designed with two sets of isolation protection systems for production test oil and finished product delivery oil (that is, the test equipment uses circulating oil and the product is shipped with new oil), to avoid dust, iron filings, welding slag and other fine particles in the test equipment and oil circuit from mixing into the finished product, ensuring the consistency of the product during long-term use and avoiding quality risks. In addition, the equipment meets the requirements of automatic control of the refueling volume, and the refueling volume can be set according to the size of the equipment, which increases the compatibility of use while ensuring the consistency of the refueling volume of the product.

[0036] This automated liquid-cooled charging pile tester features a built-in universal wheel structure, an air compressor, and a booster device at the bottom. It's self-contained and requires only a power connection. This automated liquid-cooled charging pile tester can be moved as needed, and it's not restricted by the factory's air compressor's location requirements. It's compatible with a wider range of environments and facilitates production testing.

[0037] This automated liquid-cooled charging pile test equipment meets the full automation testing requirements for liquid-cooled charging piles. The inlet and outlet cooling pipes of the liquid-cooled charging piles are connected to the self-sealing quick-connect plugs on the liquid-cooled complete unit test equipment using self-sealing quick-connect plugs, ensuring convenient testing of the entire pile and increasing personnel efficiency. By switching the cooling pipes, single-gun and dual-gun simultaneous testing can be achieved, increasing equipment compatibility and reducing investment costs.

[0038] This new automated liquid-cooled charging pile testing equipment has its own circulating oil tank, which can meet the needs of two systems for production testing oil and finished product delivery oil, avoiding the test oil from being mixed into the finished product, ensuring product quality. This new automated liquid-cooled charging pile testing equipment automatically and accurately controls the refueling amount according to the set value to ensure consistent product filling amount.

[0039] Through the complete set of tests of the utility model's automated liquid-cooled charging pile test equipment, the consistency of product quality can be guaranteed. During the test, only one insertion is required. The entire test process can be realized, from the airtightness of the liquid cooling system, the oil filling of the liquid-cooled charging pile, heating aging, real-time monitoring of flow, pressure, temperature, etc. during the aging process, the cycle test oil draining of the liquid cooling system after testing, and then the airtightness of the whole machine for the second time, automatic and accurate oil filling of the equipment after the test is completed, to delivery. The test results can be generated in the form of documents for easy storage and subsequent search. At the same time, through real-time monitoring of the test process, risks can be identified in advance. The equipment is easy to install and use. At the same time, compared with the current individual tests, it greatly increases the manpower efficiency of production, reduces product quality anomalies, and increases product reliability.
