Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a disconnector operation detection device. Background Technique

[0002] The disconnector is an important part to ensure the safe operation of power equipment. Before use, it should be checked for electricity to ensure that its electrical performance complies with the specified standards. The performance of the disconnector product, such as loop resistance, withstand voltage, current, on-off, etc., needs to be detected. And the test of the disconnector current value is an important step to judge whether the switch is in poor contact. Before the detection process of the existing disconnector detection device, the disconnector needs to be fixed to prevent loosening during detection. In most of the existing detection devices, the switch to be tested is manually loaded by workers, and the detection equipment efficiency is not high. There is a need for a disconnector operation detection device.

[0003] On this basis, after retrieval, the Chinese patent application number 201811414778.1 discloses and authorizes a disconnector detection platform device; the present invention discloses a disconnector detection platform device, including a frame, a swing rod mechanism, an electric mechanism, and an automatic control system. A fixture for fixing the disconnector is installed on the frame. After the worker clamps the disconnector to be detected through the fixture, the detection component is started to detect the switch. The qualified and unqualified disconnectors are manually taken out and stored separately;

[0004] It can be seen that the above-mentioned utility model patent has deficiencies: the structure and function of the traditional disconnector detection equipment are simple. Although it can realize the work of detecting the switch, the device lacks the functions of automatic feeding and automatic discharging. The traditional detection equipment requires manual operation for feeding. However, when there are a large number of disconnectors to be detected during work, the method of manually taking the workpieces to be detected is time-consuming and laborious, reducing the working efficiency of the device.

[0005] In view of the above problems, a disconnector operation detection device is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a disconnector operation detection device. Using this device for work, it solves the problem that the structure and function of the traditional disconnector detection equipment in the above background are simple. Although it can realize the work of detecting the switch, the device lacks the functions of automatic feeding and automatic discharging. The traditional detection equipment requires manual operation for feeding. However, when there are a large number of disconnectors to be detected during work, the method of manually taking the workpieces to be detected is time-consuming and laborious, reducing the working efficiency of the device.

[0007] To achieve the above object, the present utility model provides the following technical solutions: An isolating switch operation detection device includes a detection chamber, inside which a clamping assembly and a detection ammeter are arranged. On both sides of the detection chamber, there are transmission chamber assemblies, and the two transmission chamber assemblies are communicated with the detection chamber. On one side of the detection chamber, there is a collection box, and on one side of the detection chamber, there is a through port. The clamping assembly includes a first long block arranged inside the detection chamber, and a long cavity is arranged on the top surface of the first long block. A positive and negative thread screw rod is rotatably connected inside the long cavity. On one side of the first long block, there is a rotating rod, and one end of the positive and negative thread screw rod is fixedly connected to one side of the rotating rod. Inside the transmission chamber assembly, there is a driving roller rotatably connected inside the transmission chamber assembly. On one side of the driving roller, there is a first motor, and the driving roller is connected to the output end of the first motor. Inside the transmission chamber assembly, there is a driven roller rotatably connected, and a conveyor belt component is sleeved between the driven roller and the driving roller. On both sides of the driven roller, there are connecting rods fixedly connected, and one end of each of the two connecting rods is fixedly connected to a first rotating roller, and the two first rotating rollers are rotatably connected inside the transmission chamber assembly.

[0008] Preferably, the clamping assembly further includes moving blocks threadedly connected to the outer periphery of the positive and negative thread screw rod, and there are two sets of the moving blocks, and both sets of moving blocks are slidably connected inside the long cavity.

[0009] Preferably, on the top of both sets of moving blocks, there are adjusting plates, and on one side of each of the two adjusting plates, there is a clamping plate fixedly connected.

[0010] Preferably, inside the transmission chamber assembly, there is also a second rotating roller rotatably connected, and there are two sets of the second rotating rollers. A belt is sleeved between the second rotating roller and the first rotating roller.

[0011] Preferably, on one side of the second rotating roller, there is a second reciprocating screw rod fixedly connected, and the second reciprocating screw rod is rotatably connected inside the transmission chamber assembly. A reciprocating block is threadedly connected to the outer periphery of the second reciprocating screw rod.

[0012] Preferably, inside the transmission chamber assembly, there is a fixed limiting rod fixedly connected, and the reciprocating block is slidably connected to the outer periphery of the fixed limiting rod, and there are two sets of the reciprocating blocks.

[0013] Preferably, on one side of the reciprocating block, there is a deviation correction long block fixedly installed, and there are two sets of the deviation correction long blocks.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. A disconnector operation detection device proposed by the utility model has transmission cavity components on both the left and right sides of the detection chamber. The transmission cavity component on the right is the feeding transmission component of the detection chamber, and the transmission cavity component on the left is the discharging transmission component of the detection chamber. The operator can place the disconnector to be tested on the conveyor belt component in the feeding transmission cavity component, start the motor that controls the driving roller in the transmission cavity component, so that the driving roller rotates. The driving roller will drive the conveyor belt component to drive, and the driven roller will also rotate at the same time. The transmission of the conveyor belt component can transport the disconnector above it. The switch to be tested will be conveyed into the detection chamber. At the same time, the rotation of the driven roller will drive the two connecting rods to rotate, and then the two deviation correction long blocks will make reciprocating movements of approaching and separating alternately. The two deviation correction long blocks are on both sides of the switch conveyed on the conveyor belt component. Once the switch conveyed on the conveyor belt component is displaced, after being touched and limited by the two deviation correction long blocks, the disconnector will be corrected back to the original correct track. This setting, through the cooperation of the conveyor belt component and the limiting component, can not only achieve the effect of automatically feeding the detection device, but also facilitate the deviation correction of the conveyed disconnector, prevent the switch from shifting during transportation, and reduce the practicability of the equipment;

[0016] 2. When a group of disconnectors enter the detection chamber, the transportation work in the feeding transmission cavity component can be briefly paused, and the detection work of the switch in the detection chamber can be started. After a group of switches are detected, the qualified switches are placed on the conveyor belt component in the discharging transmission cavity component, and the conveying work of the discharging transmission cavity component is started to automatically convey the qualified objects out of the detection chamber. The unqualified objects are taken out of the detection chamber and placed in the collection box. When detecting the next group of switches, the working mode in the feeding transmission cavity component can be restarted, and so on, until all the switches to be tested are detected. This can achieve the work of automatically conveying feeding and discharging through the transmission cavity component, avoid the time-consuming and laborious manual feeding, improve the practicability of the equipment, and at the same time can classify and store the qualified and unqualified switches.

[0017] 3. A disconnector operation detection device proposed by the utility model. The disconnector should be detected before use to ensure that its electrical performance meets the specified standards. The performance of the disconnector product, such as loop resistance, withstand voltage, current, and on-off, etc., needs to be detected. And the test of the disconnector current value is an important step to judge whether the switch has poor contact. The current test uses an ammeter to test the on-current and off-current of the disconnector;

[0018] 4. After the disconnecting switch is automatically transmitted into the detection chamber through the feeding transmission chamber assembly, the operator can first limit the position of the disconnecting switch through the clamping assembly, place the disconnecting switch between two clamping plates, and then rotate the rotating rod to make the positive and negative thread screw rotate until the two clamping plates firmly clamp the bottom of the disconnecting switch. After limiting the switch in the detection chamber, the worker connects the ammeter to the wiring point and the ground wire of the disconnecting switch in turn, and observes whether the current values when connected and disconnected are within the specified range; if the current value is too large, it indicates that there may be problems such as poor contact in the disconnecting switch, and it needs to be repaired. Then, the unqualified disconnecting switch is taken out from the detection chamber and placed in the collection box for temporary storage; the qualified switch is placed inside the discharging transmission chamber assembly on the left side of the detection chamber and automatically sent out of the detection chamber through the conveyor belt component in the discharging transmission chamber assembly. The qualified switch is moved to the designated location through the transmission chamber assembly. This setting can limit and fix the disconnecting switch before the detection process of the existing disconnecting switch detection device, preventing the switch from being easily loosened or displaced during detection, resulting in detection errors and reducing the practicality of the device.

[0032] In summary: For an isolating switch operation detection device proposed by the present utility model, transmission cavity components 2 are provided on both the left and right sides of the detection chamber 1. The transmission cavity component 2 on the right is the feeding transmission component for the detection chamber 1, and the transmission cavity component 2 on the left is the discharging transmission component for the detection chamber 1; the operator can place the isolating switch to be tested on the conveyor belt component 21 in the feeding transmission cavity component 2, turn on the motor controlling the driving roller 22 in the transmission cavity component 2, so that the driving roller 22 rotates. The driving roller 22 will drive the conveyor belt component 21 to drive, and the driven roller 23 will also rotate simultaneously. The transmission of the conveyor belt component 21 can transport the isolating switch above it. The switch to be tested will be conveyed into the detection chamber 1. At the same time, the rotation of the driven roller 23 will drive two connecting rods 24 to rotate. The connecting rods 24 will drive two first rotating rollers 25 to rotate. Through the transmission effect of the belt 26, two second rotating rollers 28 will rotate. The two second rotating rollers 28 will drive two second reciprocating screw rods 27 to rotate. The driving of the two second reciprocating screw rods 27 will cause two reciprocating blocks 291 to make horizontal reciprocating movements along the fixed limiting rod 29. Furthermore, two deviation - correcting long blocks 292 will make reciprocating movements of approaching and separating from each other alternately. The two deviation - correcting long blocks 292 are located on both sides of the switch conveyed on the conveyor belt component 21. Once the switch conveyed on the conveyor belt component 21 is misaligned, after being touched and limited by the two deviation - correcting long blocks 292, the isolating switch will be corrected back to the original correct track. This setting, through the cooperative work of the conveyor belt component 21 and the limiting component, can not only achieve the effect of automatically feeding the detection device, but also facilitate the deviation - correcting work of the conveyed isolating switch, prevent the switch from shifting during transportation, and reduce the practicality of the equipment. When a group of isolating switches enter the detection chamber 1, the transportation work in the feeding transmission cavity component 2 can be temporarily paused, and the detection work of the switch in the detection chamber 1 can be started. After a group of switches are detected, the qualified switches are placed on the conveyor belt component 21 in the discharging transmission cavity component 2, and the conveying work of the discharging transmission cavity component 2 is started to automatically convey the qualified objects out of the detection chamber 1. The unqualified objects are taken out of the detection chamber 1 and placed in the collection box 4. When detecting the next group of switches, the working mode in the feeding transmission cavity component 2 can be restarted, and so on, until all the switches to be tested are detected. This can realize the work of automatically conveying and feeding as well as discharging through the transmission cavity component 2, avoid the time - consuming and laborious manual feeding, improve the practicality of the equipment, and at the same time can classify and store the qualified and unqualified switches;

[0033] Before use, the disconnecting switch should be tested to ensure that its electrical performance meets the specified standards. The loop resistance, withstand voltage, current, on-off and other performances of the disconnecting switch products need to be tested. The test of the current value of the disconnecting switch is an important step to judge whether the switch has poor contact. The current test uses an ammeter to test the on-current and off-current of the disconnecting switch. After the disconnecting switch is automatically transferred into the detection chamber 1 through the feed transmission chamber assembly 2, the operator can first limit the position of the disconnecting switch through the clamping assembly 3, place the disconnecting switch between the two clamping plates 37, and then rotate the rotating rod 36 to make the forward and reverse thread screw 33 rotate. When the forward and reverse thread screw 33 rotates forward, it will drive the two moving blocks 34 to move closer to each other along the long cavity 32. Then, the two adjusting plates 35 and the two clamping plates 37 will move closer to each other until the bottom of the disconnecting switch is stably clamped by the two clamping plates 37. After the switch is limited in the detection chamber 1, the worker connects the ammeter to the wiring point and the ground wire of the disconnecting switch in turn, and observes whether the current values at the time of connection and disconnection are within the specified range. If the current value is too large, it means that there may be problems such as poor contact in the disconnecting switch and it needs to be repaired. Then, the unqualified disconnecting switch is taken out from the detection chamber 1, and the rotating rod 36 is rotated reversely to make the forward and reverse thread screw 33 rotate reversely. Then, the two adjusting plates 35 and the two clamping plates 37 will move away from each other until the two clamping plates 37 are both far away from the disconnecting switch. The unqualified switch is placed in the collection box 4 for temporary storage. The qualified switch is placed inside the discharge transmission chamber assembly 2 on the left side of the detection chamber 1 and is automatically sent out of the detection chamber 1 through the conveyor belt component 21 in the discharge transmission chamber assembly 2. The qualified switch is moved to the designated place through the transmission chamber assembly 2. This setting can limit and fix the disconnecting switch before the detection process of the existing disconnecting switch detection device, so as to prevent the switch from being easily loosened or displaced during the detection, resulting in detection errors and reducing the practicability of the device.
