Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to an insulating glove air tightness detector and a use method thereof. Background Art

[0002] When performing daily live operations in distribution networks, insulating gloves are used as protective equipment for direct contact with live parts. Even if the leak is so small that it cannot be observed by the naked eye, a considerable leakage current will be generated when contacting the live parts, seriously endangering the personal safety of the operators. Therefore, it is very important to check the air tightness of insulating gloves. Usually, to check whether the insulating gloves are leaking, one method is to use a simple leakage point detection method, that is, hold the two sides of the upper opening of the insulating gloves with both hands, and roll the gloves towards the fingers. When rolled to a certain extent, the internal air pressure increases due to the reduction in volume, and the finger part bulges. At this time, the ears or lips are used to sense whether there is leakage for detection; or a simple manual air pump is used, and a diaphragm stop-type reversing valve is used to ensure effective shutdown, and air is continuously pumped into the insulating gloves to expand their volume and bulge the finger part, and then the hearing or touch is used to sense whether there is leakage; the above two methods both use the hearing and touch of the inspectors to identify whether there is leakage, which is easily affected by the environment and relies on the subjective feelings and experience of the operator to draw conclusions and judgments. It is not objective and is easy to cause misjudgment. In addition, the inflation test requires the gloves to expand to 1.2-1.5 times of the original state. At the same time, this manual inspection method lacks rigor, has no means of measuring and controlling the amount of air pressed in, and can only inspect a single insulating glove at a time, which is inefficient, the data is not quantified, and it is easy to cause the insulating gloves to over-expand, shortening the service life of the insulating gloves. In addition, the repeated manual rolling up of the insulating gloves and the multiple rolling and folding also reduce the service life of the insulating gloves to a certain extent, and increase the investment cost of live working equipment.

[0009] Furthermore, the first pipeline and the second pipeline are both connected to the air inlet through the main pipeline, and the exhaust port is located on the main pipeline.

[0010] Furthermore, an air pressure regulating device is provided on the main pipeline, and the air pressure regulating device includes an air pressure regulating valve and an air pressure detection gauge. The air pressure detection gauge and the air pressure regulating valve are both electrically connected to the MCU, and a preset air pressure value is set in the MCU.

[0011] Further, the display device includes two indicator lights of different colors; or, the display device includes two indicator lights of different shapes.

[0012] Furthermore, the gas pipeline adopts BNG pressure-resistant explosion-proof pipe.

[0013] The present invention also discloses a method for using an insulating glove air tightness detector. The insulating glove air tightness detector adopts the insulating glove air tightness detector in any one of the above technical solutions, and comprises the following steps:

[0014] S100, installation steps: put the insulating glove to be tested on the interface of the glove to be tested, and fasten it by cooperating with the elastic sleeve and the annular positioning groove, select a standard glove of corresponding volume according to the model of the insulating glove to be tested, and fix the standard glove on the interface of the standard glove by threading;

[0018] S500, display step: MCU calculates the difference between the first differential pressure value and the second differential pressure value. If the difference is greater than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is unqualified; if the difference is less than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is qualified;

[0019] S600, exhaust step: the first pressure-maintaining valve, the second pressure-maintaining valve and the exhaust port are opened to exhaust.

[0020] After adopting the above technical solution, the present invention has the following advantages:

[0021] 1. By setting standard gloves of different volumes, multiple standard gloves are set in one-to-one correspondence with different types of insulating gloves, which can be used to detect different types of insulating gloves. The standard glove interface is provided with an external thread, and the different standard gloves are provided with an internal thread matched with the external thread. The standard gloves of different volumes can be installed on the standard glove interface through the internal thread and the external thread to ensure the air tightness between the standard gloves and the standard glove interface; the glove interface to be tested is provided with an annular positioning groove, and different types of insulating gloves to be tested can be put on the glove interface to be tested, and the insulating gloves to be tested are tightly put on the glove interface to be tested by an elastic band to ensure the air tightness between the insulating gloves to be tested and the glove interface to be tested; by setting multiple inflation times t1, different types of insulating gloves to be tested can choose different inflation times, so that the volume of the insulating gloves to be tested after inflation is equal to the volume of the corresponding standard gloves, so that the same insulating glove air tightness tester can detect different types of insulating gloves. By setting the pressure stabilization time, the first pressure holding time and the second pressure holding time, after inflation for time t1, the air inlet valve is closed to enter the pressure stabilization state, after pressure stabilization for time t2, the first pressure holding valve and the second pressure holding valve are closed to enter the pressure holding state, after pressure holding for time t3, the differential pressure sensor works to detect and obtain the first differential pressure value, and then after pressure holding for time t4, the differential pressure sensor works to detect and obtain the second differential pressure value. When the difference between the first differential pressure value and the second differential pressure value is greater than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is unqualified; when the difference between the first differential pressure value and the second differential pressure value is less than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is qualified. By setting the pressure stabilization time, the accuracy and reliability of the insulating glove air tightness tester are improved, and by comparing the difference between the differential pressure values ​​after the first pressure holding time and the second pressure holding time, the accuracy and reliability of the insulating glove air tightness tester are further guaranteed.

[0022] 2. The standard gloves are metal gloves. To ensure the air tightness of the standard gloves, the volume of the standard gloves is 1.5 times the volume of the corresponding insulating gloves before inflation. The insulating gloves to be tested are inflated to 1.5 times the original state before a differential pressure test is performed to ensure that the air pressure inside the insulating gloves to be tested is consistent with the air pressure inside the standard gloves, thereby improving the accuracy of the insulating gloves air tightness tester.

[0023] 3. By setting up two test glove interfaces, two insulating gloves can be tested at the same time, which improves the detection efficiency. By setting up two display devices, the detection results of the two test insulating gloves can be viewed separately without interfering with each other.

[0024] 4. By setting two second pipelines, the two second pipelines are respectively connected to the interfaces of the two gloves to be tested, so that the detection of the two insulating gloves to be tested is independent of each other and will not affect each other. At the same time, the two second pipelines are respectively located on both sides of the first pipeline and are symmetrically arranged along the first pipeline, so as to minimize and offset the pressure change caused by the leakage of the pressure-maintaining valve and the pipeline, so that the two insulating gloves to be tested are under the same detection conditions as much as possible.

[0025] 5. The present invention also discloses a method for using an insulating glove air tightness tester. The insulating glove air tightness tester can detect insulating gloves of different types, thereby improving the detection efficiency of the insulating gloves air tightness and reducing the detection cost. The differential pressure detection method is used to detect, thereby overcoming the distortion of the detection value caused by the barometer error or the external environment in the existing detection work, thereby improving the detection accuracy and resolution. The voltage stabilization step and the pressure maintenance detection step greatly reduce the impact of the external environment and the air pressure change, thereby improving the detection accuracy. The display step intuitively reflects the air tightness result of the insulating glove to be tested, thereby avoiding the problem of low resolution in the existing detection work.

There are multiple t1s and they correspond to different types of insulating gloves to be tested one by one. Different types of insulating gloves to be tested can choose different inflation times. In this embodiment, there are three t1s, corresponding to small insulating gloves, medium insulating gloves and large insulating gloves, respectively. t1 is set according to the time when the insulating gloves to be tested are inflated to 1.5 times the volume, so that the volume of the insulating gloves to be tested after inflation is equal to the volume of the standard gloves. The box body 100 is provided with a power switch 170, a start key 180, an air inlet 110, a standard glove interface 120, a glove interface to be tested 130, an exhaust port 140, a model setting key 150 for selecting t1, and a display device for displaying the air tightness test result of the glove to be tested. The start key 180 is connected to the MCU through a wire. The model setting key 150 includes three setting keys corresponding to small insulating gloves, medium insulating gloves and large insulating gloves, respectively. The three setting keys are printed with the fonts "small", "medium" and "large" respectively, which is convenient for the operator to set.The gas pipeline includes a first pipeline 400 connecting the air inlet 110 and the standard glove interface 120, a second pipeline 500 connecting the air inlet 110 and the glove interface 130 to be tested, and a third pipeline 600 connecting the first pipeline 400 and the second pipeline 500. The air inlet 110 is connected to the inflation device 700 and an air inlet valve 111 is provided at the air inlet 110. A first pressure-maintaining valve 410 is provided in the first pipeline 400, a second pressure-maintaining valve 510 is provided in the second pipeline 500, and a differential pressure sensor 610 is provided in the third pipeline 600. The air inlet valve 111, the first pressure-maintaining valve 410, and the second pressure-maintaining valve 510 are all diaphragm solenoid valves and are all connected to the MCU through wires. The control module can control their opening and closing through the MCU. The standard glove interface 120 is provided with an external thread 121, and the plurality of standard gloves 200 are provided with an internal thread matched with the external thread 121. Standard gloves of different volumes can be installed on the standard glove interface by matching the internal thread with the external thread, thereby ensuring the air tightness between the standard gloves and the standard glove interface; the glove interface 130 to be tested is provided with an annular positioning groove 131, and different types of insulating gloves to be tested can be put on the glove interface to be tested, and the insulating gloves to be tested are tightly put on the glove interface to be tested through the elastic band 132, and the elastic band will not cause damage to the insulating gloves to be tested, while ensuring the air tightness between the insulating gloves to be tested and the glove interface to be tested, so that the same insulating glove air tightness tester can detect insulating gloves of different types.

[0035] After the air inlet valve 111 is opened and the inflation device 700 starts working, the timer starts timing. After time t1, the air inlet valve 111 is closed and the pressure stabilization state is entered. The timer restarts timing. After time t2, the first pressure maintaining valve 410 and the second pressure maintaining valve 510 are closed and the pressure maintaining state is entered. The timer restarts timing. After time t3, the differential pressure sensor 610 works to measure the first differential pressure value, and the timer restarts timing. After time t4, the differential pressure sensor 610 works to measure the second differential pressure value. The MCU calculates the difference between the first differential pressure value and the second differential pressure value. If the difference is greater than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is unqualified; if the difference is less than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is qualified, the first pressure maintaining valve 410, the second pressure maintaining valve 510 and the exhaust port 140 are opened to exhaust, and the power switch 170 is turned off to complete the detection. By setting the voltage stabilization time, the accuracy and reliability of the insulating glove air tightness tester are improved. By comparing the difference in differential pressure values ​​after the first pressure holding time and the second pressure holding time, the accuracy and reliability of the insulating glove air tightness tester are further guaranteed.

[0036] In this embodiment, two glove interfaces 130 to be tested are provided, and two insulating gloves can be tested at the same time, which improves the detection efficiency and reduces the detection cost; two display devices are also provided and are arranged one-to-one corresponding to the two glove interfaces 130 to be tested. By providing two display devices, the detection results of the two insulating gloves to be tested can be viewed separately without interfering with each other.

[0037] Two second pipes 500 are also provided, and the two second pipes 500 are respectively connected to the two glove interfaces 130 to be tested, so that the detection of the two insulating gloves to be tested is independent of each other and will not affect each other. At the same time, the two second pipes 500 are respectively located on both sides of the first pipe 400 and are symmetrically arranged along the first pipe 400, so as to minimize and offset the pressure change caused by the leakage of the pressure-maintaining valves and pipes on both sides, so that the two insulating gloves to be tested are under the same detection conditions as much as possible.

[0038] The two glove interfaces 130 to be tested are respectively provided with selection buttons 190, and the selection buttons 190 can control the opening of the second pressure-maintaining valve 510 in the corresponding second pipeline 500. If the two glove interfaces 130 to be tested detect two insulating gloves at the same time, the two selection buttons 190 are pressed. If only one of the glove interfaces to be tested is used to detect insulating gloves, the selection button corresponding to the working glove interface to be tested is pressed, and the second pressure-maintaining valve in the second pipeline connected to the glove interface to be tested where the selection button is not pressed is always in a closed state, thereby achieving the ability to detect two insulating gloves at the same time or to detect only one insulating glove.

[0039] The first pipeline 400 and the second pipeline 500 are both connected to the air inlet 110 through the main pipeline 800. The exhaust port 140 is located on the main pipeline 800. An exhaust valve 141 is provided at the exhaust port 140. The exhaust valve 141 is connected to the MCU through a wire. After the detection is completed, the exhaust valve is opened to exhaust.

[0040] An air pressure regulating device 900 is provided on the main pipeline 800. The air pressure regulating device 900 includes an air pressure regulating valve 910 and an air pressure detection gauge 920. The air pressure detection gauge 920 and the air pressure regulating valve 910 are both electrically connected to the MCU. A preset air pressure value is set in the MCU. If the internal pressure value measured by the air pressure detection gauge 920 is greater than the preset pressure value after inflation is completed, the internal pressure value is made equal to the preset pressure value through the air pressure regulating valve 910, thereby ensuring the accuracy of the detection by the insulating glove air tightness tester.

[0041] The display device includes two indicator lights 160 of different colors, specifically a red indicator light indicating that the air tightness of the insulating glove to be tested is unqualified and a green indicator light indicating that the air tightness of the insulating glove to be tested is qualified.

[0042] It can be understood that the display device may also include two indicator lights of different shapes.

[0043] Specifically, the inflation device 700 is an electric inflation pump, and the gas pipeline adopts BNG pressure-resistant explosion-proof pipe to ensure the safety of the detector.

[0044] The present invention also discloses a method for using an insulating glove air tightness detector, wherein the insulating glove air tightness detector is any of the insulating glove air tightness detectors in the above technical solutions, and specifically comprises the following steps:

[0045] S100, installation steps: put the insulating glove to be tested on the interface of the glove to be tested, and fasten it by cooperating with the elastic sleeve and the annular positioning groove, select a standard glove of corresponding volume according to the model of the insulating glove to be tested, and fix the standard glove on the interface of the standard glove by threading;

[0046] S200, inflation step: turn on the power switch, select the corresponding inflation time t1 according to the model of the insulating gloves to be tested through the model setting key, press the start key, the air inlet valve opens, the inflation device starts to inflate, and the timer starts timing;

[0047] S300, pressure stabilization step: after time t1, the air intake valve is closed and the timer is restarted;

[0048] S400, pressure-maintaining detection step: after time t2, the first pressure-maintaining valve and the second pressure-maintaining valve are closed, and the timer is restarted; after time t3, the differential pressure sensor works to measure a first differential pressure value, and the timer is restarted; after time t4, the differential pressure sensor works to measure a second differential pressure value;

[0049] S500, display step: MCU calculates the difference between the first differential pressure value and the second differential pressure value. If the difference is greater than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is unqualified; if the difference is less than the preset differential pressure value, the display device displays that the air tightness of the insulating glove to be tested is qualified;

[0050] S600, exhaust step: the first pressure-maintaining valve, the second pressure-maintaining valve and the exhaust port are opened to exhaust.

[0051] The insulating glove air tightness tester can detect insulating gloves of different models, thereby improving the detection efficiency and reducing the detection cost. The detection is performed by a differential pressure detection method, thereby overcoming the distortion of the detection value caused by the barometer error or the external environment in the existing detection work, thereby improving the detection accuracy and resolution. The external environment influence and air pressure change are greatly reduced through the voltage stabilization step and the pressure maintenance detection step, thereby improving the detection accuracy. The air tightness result of the insulating glove to be tested is intuitively reflected through the display step, thereby avoiding the problem of low resolution in the existing detection work.

[0052] There is also S210, a pressure regulating step, between the inflation step and the pressure stabilization step: the air pressure detection meter detects the air pressure in the main pipeline. If the measured value is not equal to the preset air pressure value, the air pressure regulating valve adjusts the air pressure in the main pipeline so that the air pressure in the main pipeline reaches the preset value.
