Description

Technical Field

[0001] This utility model relates to switch detection equipment, specifically a power-off switch detection device. Background Technology

[0002] Electric tricycles are typically equipped with power-off switches to cut off power when the vehicle is parked. However, existing power-off switches on the market have mechanical components that require testing before use. This testing should assess the tactile feedback and pressure applied to the buttons or operating parts, ensuring smooth and sensitive mechanical operation. During use, the switch should be operated repeatedly with varying pressure to observe its ability to smoothly switch on and off without any jamming or sticking. This testing requires continuous manual operation of the switch, which is impractical. Therefore, a device capable of continuously testing the performance of power-off switches is urgently needed.

[0003] Currently, a utility model patent with publication number CN212111677U discloses an air switch testing device, which relates to the field of testing device technology. The key points of its technical solution are: it includes a fixing plate, a connecting plate welded to the rear side of the fixing plate, and a placement groove opened on the top of the fixing plate. A first contact is fixedly installed inside the placement groove. Two symmetrically arranged springs are fixedly installed on one side of the inner wall of the placement groove. A fixing post is welded to one side of the spring. The first contact can contact the input terminal of the air switch, thereby inputting current into the air switch to ensure the testing work. The air switch can be fixed by the springs and the fixing post, thereby limiting the range of motion of the air switch.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN212111677U adopts a spring fixing and sliding test method, which can reduce the time used in testing air switches and facilitate the operation of staff, further reducing the cost of testing. However, this patent is mainly used for testing air switches and cannot be used to test power-off switches. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a power-off switch testing device that can continuously test the power-off switch and effectively detect the life limit of the power-off switch.

[0006] To achieve the above objectives, this utility model provides a power-off switch detection device, comprising a detection water tank, a mounting column, a reciprocating cylinder, a power-off switch fixing bracket, a solenoid valve, a PLC data cable, a detection water tank base, and an air hose connector. The reciprocating cylinder is mounted inside the detection water tank via the mounting column. The telescopic end of the reciprocating cylinder is connected to a cylinder head. The power-off switch fixing bracket is mounted at the lower end of the mounting column. The reciprocating cylinder is connected to the solenoid valve via a cylinder air pipe. The lower part of the solenoid valve is connected to an air hose connector, which is connected to a compressed air pressure reducing valve via a pipeline. The compressed air pressure reducing valve is connected to an external air source via a compressed air inlet pipe. A PLC control system is mounted at the rear of the detection water tank via a PLC mounting bracket. The solenoid valve is connected to the PLC control system via a PLC data cable. The PLC control system is connected to the power-off switch on the power-off switch fixing bracket via a power-off switch signal cable.

[0007] In addition, the power failure switch detection device proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the lower part of the detection water tank is provided with a detection water tank base.

[0009] As a further improvement of this utility model, the detection water tank base is equipped with a threaded rubber gasket.

[0010] As a further improvement of this utility model, the detection water tank is lower in the front and higher in the back, and the PLC control system is installed at the higher rear part of the detection water tank.

[0011] As a further improvement of this utility model, a drain valve is installed at the bottom of the detection water tank.

[0012] By means of the above solution, this utility model has at least the following advantages: by controlling the power-off switch to open and close continuously on the power-off switch fixed support by a reciprocating cylinder, it is possible to effectively detect the tactile feel of the buttons or operating parts of the power-off switch, whether the pressing pressure is appropriate, and whether the mechanical action is smooth and sensitive. It can also detect the continuity of the power-off switch circuit, whether there is a short circuit or open circuit, and can promptly alarm and automatically stop when the power-off switch signal cable detects an abnormality in the power-off switch, and can effectively detect the life limit of the power-off switch.

The PLC control system 7 is connected to the power-off switch on the power-off switch fixing bracket 4 through the power-off switch signal cable 10.

[0018] A utility model patent with the publication number CN212111677U describes an air switch testing device (hereinafter referred to as "the patent"). This patent uses a spring-fixed and sliding test method, which can reduce the time spent testing air switches and facilitate operation by staff, further reducing testing costs. However, this patent is mainly used for testing air switches and cannot test power-off switches. In contrast, this invention provides a mounting position for the power-off switch by installing a column 2 and a power-off switch fixing support 4, and uses a reciprocating cylinder 3 to test the power-off switch, which can effectively detect the life limit of the power-off switch.

[0019] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 1 and Figure 2 As shown, the lower part of the detection water tank 1 is provided with a detection water tank base 14.

[0020] To further optimize the working efficiency and improve the stability of the equipment, the test water tank base 14 is equipped with threaded rubber gaskets. For easy installation and removal of the power-off switch, the test water tank 1 is positioned with a lower front and higher rear, and the PLC control system 7 is installed at the higher rear part of the test water tank 1. To facilitate drainage after testing, a drain valve is installed at the bottom of the test water tank 1.

[0021] To use the equipment, simply install the power failure switch detection device and connect the corresponding pipelines. The equipment is then ready for use.

[0022] When this utility model is used, its specific operation is as follows:

[0023] The power-off switch is installed on the power-off switch mounting bracket 4. The PLC control system 7 is connected to the power-off switch via the power-off switch signal cable 10. Then, a reciprocating cylinder 3 is connected to the power-off switch lever. Water is filled into the detection water tank 1 until it is completely submerged above the power-off switch. The reciprocating cylinder 3 drives the power-off switch to reciprocate. The power-off switch circuit is connected to the power-off switch signal cable 10. Under normal conditions, the indicator light on the PLC control system 7 flashes green. Under abnormal conditions, the indicator light flashes yellow. Under abnormal conditions, the indicator light turns red after 10 seconds. When the red light turns on, the equipment stops running. The PLC control system 7 is responsible for functions such as setting the number of detections and handling abnormal situations.

[0024] In summary, the power-off switch detection device of this utility model embodiment controls the power-off switch to continuously open and close on the power-off switch fixed support 4 through the reciprocating cylinder 3. It can effectively detect the tactile feel of the buttons or operating parts of the power-off switch, whether the pressing pressure is appropriate, and whether the mechanical action is smooth and sensitive. It can also detect the continuity of the power-off switch circuit, whether there is a short circuit or open circuit, and can promptly alarm and automatically stop when the power-off switch signal cable 10 detects an abnormality in the power-off switch. It can effectively detect the life limit of the power-off switch.
