Description
Technical Field
[0001] The invention relates to the technical field of electrical testers, and in particular to a tester for electrical comprehensive safety performance. Background Art
[0002] During operation, electrical equipment needs to be maintained in a timely manner to improve the safety of the electrical equipment and avoid damage to the electrical equipment due to failure of components within the electrical equipment, or even threats to surrounding personnel and the overall power system.
[0003] When conducting safety inspections on electrical equipment, existing electrical safety performance testing instruments have a single detection capability. When conducting comprehensive safety performance inspections on electrical equipment, multiple devices need to be used. By repeatedly replacing different testing instruments, the comprehensive safety performance inspection of electrical equipment is completed. The inspection process is relatively cumbersome and the inspection efficiency is low. At the same time, when using different gas detection components, it is necessary to equip multiple air intake pumps or constantly disassemble and assemble the connection between the gas detection components and the air intake pump. The former increases the difficulty of carrying multiple gas detection components, and the latter increases the inspection time and reduces the inspection effect. At the same time, when working with different gas or power detection components, it is impossible to uniformly supply power and display the detection data, which increases the difficulty of powering different detection components and the difficulty of comprehensively analyzing and comparing various types of data. Summary of the invention

[0009] Preferably, the tops of the first mounting groove and the second mounting groove are both penetrated, the first mounting groove is connected with a matching groove, the matching groove is arranged on the mounting frame, and the air inlet head is loosely matched with the matching groove, so that the gas detection module can be inserted into the first mounting groove without obstruction.
[0010] Preferably, the air intake pump input end is connected to a ventilation pipe, and the output end is connected to an exhaust pipe, and the ventilation pipe is connected to a connecting component at one end away from the air intake pump.
[0011] Preferably, the connecting component includes a connecting pipe, an external gear and a reset spring piece. The inner circumference of one end of the connecting pipe is threadedly connected to the ventilation pipe, and the inner circumference of one end away from the ventilation pipe is threadedly matched with the outer circumference of the connecting head. The outer circumference of the middle part of the connecting pipe is coaxially fixedly connected with an external gear. A reset spring piece is connected between the connecting pipe and the main body. A plurality of toggle racks are fixedly connected to the control ring. The external gear and the toggle rack are meshed with each other.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The present invention inserts different gas detection components and power detection components into the installation frame, and completes the comprehensive detection of different power equipment through the combination of the two types of detection components, without the need to repeatedly replace multiple detection devices, thereby improving the detection efficiency; and through the rotation control of the control ring, only one detection module is in the power-on state at the same time, avoiding other detection modules from being triggered by mistake and reducing the consumption of power supply energy; and various types of data are recorded and displayed through the same display screen, which is convenient for comprehensive analysis of the data.
[0016] 2. When the gas detection module is used in the present invention, the control ring is rotated, and the conductive contact on the control ring is electrically contacted with the energized end at the bottom of the gas detection component in the gas detection module, so that the detection data of the gas detection component can be transmitted to the display screen, which is convenient for the user to check. The control ring rotates and the toggle rack rotates at the same time. The movement of the toggle rack drives the outer gear to rotate, which drives the connecting pipe to rotate spirally and snap into the ventilation head, so that the gas detection component and the air intake pump are connected. Finally, the air intake head is connected to the device on the tested side, and the air intake pump is started to draw the gas on the tested side into the interior of the gas detection component, which is convenient for the gas detection component to complete the detection of the gas.

[0017] 3. When the power detection module is used in the present invention, the control ring is rotated to make the conductive contact on the control ring electrically contact with the energized end at the bottom of the power detection component in the power detection module, and finally the power connection end is electrically connected to the device on the tested side, so that the detection data of the power detection component can be transmitted to the display screen, which is convenient for the user to check. By rotating the control ring, the power detection of the device on the tested side can be carried out through a variety of power detection components.
[0018] 4. During the rotation of the control ring of the present invention, the limit block in the upper limit assembly of the control ring is moved out from the limit groove on the installation frame and inserted into the limit groove on the outer shell of the two types of detection modules, thereby forming a fixing effect on the two types of detection modules, preventing the detection modules from loosening or even detaching from the installation frame during work; after the detection module completes the detection, the control ring rotates in the opposite direction to disengage the limit block from the limit groove on the outer shell of the detection module, thereby facilitating the direct extraction of the gas detection module and making the installation and replacement of the detection module more convenient.
[0019] 5. In the present invention, a small magnetic block is arranged in the limit block.

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Reference Figure 1 A tester for comprehensive electrical safety performance includes a main body 1, a mounting frame 2 is fixedly connected to the outer peripheral side of the main body 1, a plurality of first mounting grooves 21 and second mounting grooves 22 are provided on the mounting frame 2, a gas detection module 3 is slidably connected in the first mounting groove 21, and a power detection module 4 is slidably connected in the second mounting groove 22, the gas detection module 3 includes a shell and a gas detection component 31, the gas detection component 31 is located in the shell, the power detection module 4 includes a shell and a power detection component 41, the power detection component 41 is located in the shell, and the power detection component 41 is not shown in the figure, wherein the gas detection component 31 and the power detection component 41 adopt detection components in the prior art for detecting gas pressure, temperature, concentration and circuit current, voltage, resistance and other data, so that comprehensive detection of different electrical equipment is completed by combining different gas detection components 31 and power detection components 41, without repeatedly replacing multiple detection equipment, thereby improving detection efficiency.
[0028] The input end of the gas detection component 31 is connected to an air inlet head 32, and the output end is connected to a connecting head 33. The air inlet head 32 is used to connect to the device on the inspected side. The tops of the first mounting groove 21 and the second mounting groove 22 are both penetrated. The first mounting groove 21 is connected to a matching groove, and the matching groove is provided on the mounting frame 2. The air inlet head 32 and the matching groove are matched with each other in a clearance, so that when the gas detection module 3 is inserted into the first mounting groove 21, the air inlet head 32 can pass through the matching groove without obstruction.
[0029] The input end of the power detection component 41 is electrically connected to the power connection terminal 42, which is used to electrically connect to the device on the detected side. The limit groove 23 is opened on the shell, and the bottom of the gas detection component 31 and the power detection component 41 are both electrically connected to the power supply terminal 43.
[0030] Reference Figure 2 An air intake pump 5 is installed in the main body 1, and the input end of the air intake pump 5 is connected to a connecting component 53. The input end of the air intake pump 5 is connected to a ventilation pipe 51, and the output end is connected to an exhaust pipe 52. The end of the ventilation pipe 51 away from the air intake pump 5 is connected to the connecting component 53, and the end of the connecting component 53 away from the ventilation pipe 51 is connected to the gas detection module 3. The end of the exhaust pipe 52 away from the air intake pump 5 is connected to the outside world. A control ring 6 is coaxially connected to the main body 1.
[0031] Reference Figure 3 and 4 The connecting assembly 53 includes a connecting pipe 531, an external gear 532 and a reset spring 533. The inner circumference of one end of the connecting pipe 531 is threadedly connected to the vent pipe 51, and the inner circumference of one end away from the vent pipe 51 is threadedly matched with the outer circumference of the connecting head 33. The outer circumference of the middle part of the connecting pipe 531 is coaxially fixedly connected with the external gear 532. A reset spring 533 is connected between the connecting pipe 531 and the main body 1. The reset spring 533 adopts a spring-type structure, wherein the inner end of the spring-type reset spring 533 is connected to the outer side of the connecting pipe 531. It is fixedly connected, and the outer end is axially slidably connected to the main body 1 along the connecting tube 531, so that when the connecting tube 531 spirally rotates, the reset spring 533 moves with the connecting tube 531 while storing force, thereby avoiding twisting of the reset spring 533 to affect its working ability, and the reset spring 533 rotates and resets the connecting tube 531 after the connecting tube 531 loses external force, wherein the elastic force of the reset spring 533 on the connecting tube 531 is smaller than the rotational friction between the control ring 6 and the main body 1, thereby avoiding the reset spring 533 affecting the rotation of the control ring 6.
[0032] A plurality of toggle racks 63 are fixedly connected to the control ring 6, and the outer gear 532 is meshed with the toggle rack 63. When the control ring 6 is rotated, the toggle rack 63 moves to push the outer gear 532 to rotate, driving the connecting pipe 531 to spirally rotate on the ventilation pipe 51 and snap into the connecting head 33, connecting the gas detection component 31 and the air intake pump 5, facilitating the operation of the air intake pump 5, and drawing the gas in the device on the inspected side into the gas detection component 31 for detection; after the toggle rack 63 is removed, under the elastic force of the reset spring 533, the connecting pipe 531 rotates in the opposite direction and resets, facilitating the gas detection module 3 to be separated from the first mounting groove 21 and facilitating the replacement of the gas detection module 3.
[0033] Reference Figure 1 , a plurality of limit components 61 are connected to the control ring 6, and limit grooves 23 are provided on the outer sides of the installation frame 2, the gas detection module 3 and the power detection module 4. The limit component 61 is clamped in the limit groove 23 at one end away from the control ring 6. The limit component 61 includes a bracket 611 and a limit block 612. A plurality of brackets 611 are fixedly connected to the outer peripheral side of the control ring 6, and the bracket 611 is fixedly connected to the limit block 612 at one end away from the control ring 6. Both ends of the limit block 612 are wedge-shaped and slidably connected in the limit groove 23. The limit block 612 rotates with the control ring 6, moves from the limit groove 23 on the installation frame 2 to the limit groove 23 on the outer shell of the two types of detection modules, thereby forming a fixing effect on the detection module in the installation frame 2.
[0034] Reference Figure 5 A conductive contact 62 is fixedly connected to the control ring 6, and the conductive contact 62 is electrically connected to multiple gas detection modules 3 and power detection modules 4 on the rotation trajectory, wherein the conductive contact 62 is electrically connected to multiple power-on terminals 43 on the rotation trajectory. A display screen 8 and a power supply are installed on the main body 1, and the power supply is not shown in the figure. The air intake pump 5 and the conductive contact 62 are electrically connected to the display screen 8, and the display screen 8 is electrically connected to the power supply. The power supply supplies power to the display screen 8 and the components electrically connected to the display screen 8. After the control ring 6 rotates to make the conductive contact 62 electrically contact with the power-on terminal 43 on a detection module, this detection module can start working, so that during the detection process, only one detection module is always in a power-on state, avoiding other detection modules from being triggered by mistake and reducing the consumption of power supply energy.
[0035] A small magnetic block is embedded in the limit block 612, and ferromagnetic blocks are embedded in the outer shells of the gas detection module 3 and the power detection module 4, wherein the ferromagnetic blocks are located above the limit groove 23 in the outer shell. The magnetic attraction of the small magnetic block to the ferromagnetic block is greater than the gravity of the gas detection module 3 and the power detection module 4 themselves, thereby preventing the two types of modules from easily detaching from the installation frame 2.
[0036] Before electrical testing, firstly, the multiple gas detection modules 3 and multiple power detection modules 4 to be used are correspondingly inserted into the first installation slot 21 and the second installation slot 22 on the installation frame 2. At this time, the connecting head 33 on the output end of the gas detection component 31 in the gas detection module 3 is facing the ventilation pipe 51 on the input end of the air intake pump 5 in the main body 1. After the installation of the two types of modules is completed;
[0037] When a separate gas detection module 3 is needed, the control ring 6 is rotated to make the conductive contact 62 on the control ring 6 electrically contact with the energized end 43 at the bottom of the gas detection component 31 in the gas detection module 3, so as to facilitate the transmission of the detection data of the gas detection component 31 to the display screen 8 for the user to check;
[0038] During the rotation of the control ring 6, the toggle rack 63 on the control ring 6 rotates accordingly, meshing with the external gear 532 on the connecting pipe 531 in the connecting assembly 53. The movement of the toggle rack 63 drives the external gear 532 to rotate, driving the connecting pipe 531 to spirally rotate on the vent pipe 51 until the end of the connecting pipe 531 away from the vent pipe 51 is spirally clamped on the connecting head 33, and the gas detection component 31 and the air intake pump 5 are connected through the connecting pipe 531, and then the air intake head 32 at the input end of the gas detection component 31 is connected to the device on the detected side, and the air intake pump 5 is started to draw the gas on the detected side into the gas detection component 31, so that the gas detection component 31 can complete the gas detection;
[0039] Similarly, when a separate power detection module 4 is needed, the control ring 6 is rotated to make the conductive contact 62 on the control ring 6 electrically contact the power-on terminal 43 at the bottom of the power detection component 41 in the power detection module 4, and finally the power-on terminal 42 is electrically connected to the device to be detected, so as to facilitate the transmission of the detection data of the power detection component 41 to the display screen 8, which is convenient for the user to check;
[0040] At the same time, during the rotation of the control ring 6, the limit block 612 in the upper limit assembly 61 of the control ring 6 moves accordingly, moves from the limit groove 23 on the installation frame 2, and is inserted into the limit groove 23 on the shells of the two types of detection modules, thereby forming a fixing effect on the detection module, preventing the detection module from loosening or even detaching from the installation frame 2 during operation, and after the detection module completes the detection, the control ring 6 rotates in the opposite direction, so that the limit block 612 detaches from the limit groove 23 on the shell of the detection module, making it convenient to directly extract the detection module, and making it more convenient to install and replace the two types of detection modules;
[0041] A small magnetic block is arranged in the limit block 612. The magnetic attraction of the small magnetic block to the ferromagnetic blocks on the two types of modules is greater than the gravity of the two types of modules themselves. Therefore, when the limit assembly 61 does not fix the two types of modules, the two types of modules are prevented from easily detaching from the installation frame 2, ensuring that the two types of modules remain stable during the rotation of the rotating control ring 6.
[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
