Description

Technical Field

[0001] The present invention relates to the technical field of insulator testing, and particularly to an insulator water boiling test device and a test method thereof. Background Art

[0002] Insulators play two basic roles in overhead transmission lines, namely supporting the conductor and preventing current from returning to the ground. These two roles must be ensured. Insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulators will not play a significant role and will damage the service life and operation of the entire line. In order to ensure the electrical and mechanical properties of composite insulators, the external environment should be simulated through a water boiling test, the appearance of the product after water boiling should be observed, the degree of influence of the composite insulator by external factors should be judged, and a conclusion should be drawn.

[0003] A water boiling test tank for high-voltage composite insulators with a steam retraction function provided by a Chinese utility model patent with the publication number CN207081680U includes a tank body and a tank cover. A plurality of movable partitions that divide the tank body into several sections are evenly arranged along the axial direction in the tank body. Each section of the tank body corresponds to a tank cover, and an exhaust port is opened on the tank cover. A heating resistance wire is arranged in each section of the tank body; it also includes a water-cooled jacket. The water-cooled jacket includes a cooling water chamber and a steam channel. The steam channel is arranged vertically from bottom to top in the cooling water chamber. The lower end of the steam channel is an air inlet, and the upper end is an air outlet. The cooling water chamber is provided with a water inlet and a water outlet. The cooling water chamber is fixed on a support frame. The exhaust port of the tank cover is connected to the air inlet of the steam channel through an exhaust pipe. This water boiling test tank uses a water-cooled jacket to condense the steam. After the steam condenses into water droplets, it flows back into the water boiling test tank, which can reduce heat loss, lower energy consumption, and at the same time reduce the air humidity in the test environment.

[0004] However, the above water boiling test tank still has some defects: the evenly distributed movable partitions in the tank need to be manually loaded and unloaded. In addition, when placing the insulators, it is necessary to manually move the insulators into the tank body. After the water boiling is completed, the insulators are moved out of the tank body, or the lifting device is used to complete the taking and placing of the insulators. The labor intensity is high, the degree of automation is low, and the test cycle is long.

[0005] Therefore, the present invention proposes an insulator water boiling test device and a test method thereof to solve the above problems. Summary of the Invention

An insulator limiting plate is fixedly provided on the side of the chain plate close to the fixing rod. The insulator limiting plate is arranged on the side of the chain plate close to the telescopic rod. An ear plate detachably connected to the arc-shaped hook body of the telescopic rod is provided on the side of the chain plate away from the fixing rod. A connection hole for the arc-shaped hook body to pass through is opened on the ear plate.

The third slider is movably installed in the chute, and the planetary gear is rotatably installed on the third slider.

[0012] Further, the sealed connection assembly includes a sealing frame and a wedge block. The sealing frame is vertically installed in the box body. A first sealing strip is provided on one side wall of the sealing frame close to the corresponding partition board. A connecting plate is provided on one side of the top of the partition board close to the sealing frame. A connecting groove is formed on the top surface of the sealing frame for the connecting plate to rotate into or out of along with the partition board. The wedge block is movably installed on the sealing frame and is driven to move linearly by a first linear driver. A through groove for the wedge block to insert is formed on the connecting plate.

[0013] Further, the locking assembly includes a fixed seat and an eccentric rotating block. The fixed seat is installed on the top surface of the box body.

The eccentric rotating block is driven by a second rotating driver to rotate into the locking groove of the fixed seat, and the top surface of the eccentric rotating block abuts against the fixed seat.

[0014] Further, the lifting assembly includes a rotating arm and a fixed arm. The fixed arm is fixedly installed on one side of the box body close to the first hinge. The rotating arm is arranged above the fixed arm. The middle part of the rotating arm is hinged to the top of the fixed arm. One end of the rotating arm is movably connected to the box cover through a roller assembly, and the other end is connected to the box body through a second linear driver; The roller assembly includes two rollers and a track.

The rotating arm is arranged between the two Z-shaped side plates, and the two rollers are respectively installed in the corresponding guiding grooves in a rolling manner.

[0015] Further, the insulator boiling water test device includes a plurality of condensing pipes. Two condensing pipes correspond to each boiling water tank. Each condensing pipe is installed above the box body. The upper outlets of the two condensing pipes of the same boiling water tank are connected to each other through a first pipeline. The first pipeline is connected to the inside of the box body through a first hose. The lower outlets of the two condensing pipes of the same boiling water tank are connected to each other through a second pipeline. The second pipeline is connected to the inside of the box body through a second hose. The bottom air inlets of each condensing pipe are respectively connected to the inside of the box body through an air inlet corrugated pipe.

[0016] The test method of the above insulator boiling water test device includes: Step 1, insulator transfer: The console controls to move the insulator support frame to the material receiving position of the feeding conveyor belt in advance. The insulator to be tested is conveyed and moved by the feeding conveyor belt. When the fourth sensor detects that the insulator to be tested enters the insulator support groove of the insulator support frame, the scanning identifier scans the QR code of the insulator to be tested to obtain the size information of the insulator to be tested. The console allocates the boiling position according to the size information of the insulator to be detected and the usage of the boiling tanks in the boiling water tank, and controls the drivers of the gear drive assembly and the sealed connection assembly to adjust the positions of the partition plates covered by the boiling position, ensuring that the partition plates at both ends of the boiling position are in a vertical sealed state, and the partition plates in the middle are in a horizontal state so that the boiling tanks in the boiling position are interconnected; Step 2, insulator feeding: The console controls the drivers of the insulator moving and transferring assembly to move the insulator support frame and the insulator to be tested to the feeding position corresponding to the boiling position. Then the insulator support frame rises to lift the insulator to be tested to the set height. The console controls the drivers of the locking assembly and the lifting assembly to rotate the lids of the boiling position to the inclined half-open state. The console controls the drivers of the insulator fixing assembly to make the telescopic end of the telescopic rod extend obliquely downward to the lower part of the insulator to be tested. At the same time, the chain plate gradually unfolds obliquely downward under the action of gravity as the telescopic rod extends. When the first sensor detects that the chain plate is flattened in place, the telescopic end of the telescopic rod continues to extend forward to disengage the arc-shaped hook body from the chain plate ear plate. After the telescopic rod rotates away from the chain plate, the telescopic end retracts. The lid rotates to the vertical open state. The insulator support frame descends, and the insulator to be tested descends onto the chain plate and is supported by the insulator support frame and the chain plate together. The telescopic rod acts to make the telescopic end extend above the insulator to be tested. After the arc-shaped hook plate is connected to the chain plate ear plate, the insulator support frame descends, and the insulator to be tested is limited between the chain plate and the telescopic rod, completing the feeding; Step 3, boiling test: The console controls the drivers of the insulator fixing assembly. The telescopic end of the telescopic rod retracts to pull the chain plate to turn and bend. The chain plate pushes the insulator to be tested to move closer to the lid. When the third sensor detects that the insulator to be tested reaches the insulator limit plate, the telescopic end of the telescopic rod stops retracting. The console controls the drivers of the lifting assembly to rotate the lids of the boiling position downward to close. The insulator fixing assembly and the insulator to be tested rotate into the box body with the lid. The console controls the telescopic end of the telescopic rod to extend downward according to the liquid level height of the box detected by the fifth sensor, so that the insulator to be tested moves downward below the liquid level, and the boiling test begins; Step 4. Insulator blanking: After the water boiling is completed, the control console controls the retraction of the telescopic end of the telescopic rod, and the tested insulator moves upward. When the third sensor detects that the tested insulator reaches the insulator limit plate, the telescopic end of the telescopic rod stops retracting. Control the drivers of the locking assembly and the lifting assembly to rotate the lids of each box at the water boiling position to the inclined half-open state. The telescopic end of the telescopic rod extends obliquely downward. During the extension process, the chain plate gradually unfolds obliquely downward under the action of its own gravity and the gravity of the tested insulator as the telescopic end of the telescopic rod extends. The tested insulator rolls downward along the chain plate. When the first sensor detects that the chain plate is flattened in place, control the drivers of the insulator moving and transferring assembly to raise the insulator support frame close to the tested insulator. When the fourth sensor detects that the tested insulator enters the insulator support groove of the insulator support frame, the telescopic end of the telescopic rod continues to extend forward to separate the arc-shaped hook body from the chain plate ear plate. The telescopic rod rotates away from the chain plate and then the telescopic end retracts. The insulator support frame rises to move the tested insulator away from the chain plate. The telescopic rod acts. After the arc-shaped hook body is connected to the chain plate ear plate, the telescopic end of the telescopic rod retracts to pull the chain plate to flip and bend away from the feeding position, completing the blanking; Step 5. Insulator removal: Control the drivers of the insulator moving and transferring assembly. After the insulator support frame descends and moves, it drives the tested insulator to move above the blanking conveyor belt. The insulator support frame descends to place the tested insulator on the blanking conveyor belt, and the blanking conveyor belt conveys and removes the tested insulator.

[0017] The advantages of the present invention are as follows: The insulator water boiling test device of the present invention divides the interior of the water boiling tank into multiple water boiling tanks by arranging a partition plate in the water boiling tank. The partition plate is lifted and lowered by a gear drive assembly to realize the mutual independence and mutual connection of each water boiling tank. The control console can arrange a suitable water boiling position according to the conditions of each water boiling tank and the size of the insulator to be tested, and automatically adjust the corresponding partition plate; the insulator moving and transferring assembly realizes the automatic switching of the position of the insulator among the feeding conveyor belt, the corresponding water boiling position of the water boiling tank, and the blanking conveyor belt; by installing the insulator fixing assembly on the lid, after the insulator moving and transferring assembly moves the insulator to be tested to the insulator fixing assembly, the insulator fixing assembly can automatically enter the water boiling tank with the closing of the lid for water boiling. After the water boiling is completed, it automatically moves out of the water boiling tank with the opening of the lid, simplifying the operation procedures of separately putting the insulator to be tested into the water boiling tank and then closing the lid, and taking out the tested insulator from the water boiling tank after the lid is opened, realizing the automatic control of the entire process of insulator moving in, feeding, water boiling, blanking, and removal.

[0018] The insulator fixing component of the present invention realizes detachable connection with the end of the chain plate through the mutual cooperation of the chain plate and the telescopic rod. The end of the telescopic rod is mutually matched with the ear plate through the arc-shaped hook body, so as to realize detachable connection with the end of the chain plate. When the telescopic rod is connected to the chain plate, the chain plate and the telescopic rod respectively limit the upper and lower sides of the insulator, and due to the structural characteristics of the umbrella skirt of the insulator itself, it can be axially limited between two insulator fixing components, thereby realizing the relative fixation between the insulator and the box cover.

[0019] The insulator support frame of the present invention realizes the functions of lifting, longitudinal movement and lateral movement through the lifting structure, longitudinal movement structure and lateral movement structure, realizes the automatic switching of positions among the feeding conveyor belt, the boiling water tank and the discharging conveyor belt, and automatically adjusts the support height during loading and unloading.

[0020] The insulator boiling water tank test device of the present invention provides guarantee for realizing automatic loading and unloading of insulators by setting a sensor assembly, improves safety at the same time, and prevents operation failures.

[0021] The gear drive assembly of the present invention realizes the smooth switching between the horizontal state and the vertical state of the partition plate through the mutual cooperation of the gear ring, the planetary gear and the sun gear. The sun gear drives the planetary gear to rotate, and the planetary gear drives the partition plate to rotate around the first hinge shaft through the third slider. When the sun gear stops rotating, the planetary gear is braked by cooperating with the sun gear through the gear ring, so that the partition plate maintains the corresponding state unchanged.

[0022] The sealing connection component of the present invention realizes the sealing connection between the partition plate and the sealing frame through the mutual cooperation of the sealing frame, the connecting plate and the wedge block. When the partition plate is driven by the gear drive assembly to rotate to the vertical position, the wedge block uses its own shape characteristics to insert into the through groove of the connecting plate, so that the partition plate is tightly pressed on the first sealing strip of the sealing frame, realizing the sealing connection between the partition plate and the sealing frame, and further making the boiling water tanks on both sides of the partition plate independent of each other.

[0023] The locking component of the present invention adopts an eccentric rotating block, and the top surface of the eccentric rotating block is designed as an inclined surface. When the eccentric rotating block rotates and the inclined surface abuts against the fixed seat, it can effectively improve the connection tightness between the box cover and the box body and ensure the sealing performance between the box cover and the box body.

[0024] The rotating arm of the present invention is movably connected to the box cover through the roller assembly and cooperates with the first hinge on one side of the box cover, so that the position of one side of the box cover remains fixed, and the angle of the box cover is rotated and adjusted on the other side, realizing the rapid adjustment of the box cover angle and high position accuracy.

[0025] The present invention ensures the steam condensation and reflux of each boiling water tank by correspondingly arranging two condensing pipes for each boiling water tank, reduces liquid loss and temperature dissipation. Even if one of the condensing pipes is damaged, the other condensing pipe can still play the condensing role.

[0026] The test method of the present invention utilizes the chain plate and the telescopic rod in the insulator fixing assembly. Through the reasonable layout of the feeding position and the opening position of the box cover, the chain plate provides power by its own gravity and is limited by the arc-shaped hook body at the end of the telescopic rod, realizing the automatic flattening of the chain plate with controllable speed. It cooperates with the insulator support frame to optimize the support height in each process of the insulator support frame, achieving the automatic loading and unloading of the insulator. In the boiling water test stage, the telescopic rod drives the chain plate to push the insulator to be tested to move as close as possible to the box cover. On the one hand, it reduces the requirement for the width dimension of the opening at the top of the box body. On the other hand, it reduces the moment exerted by the insulator on the box cover and the load-bearing of the box cover and the lifting assembly. After the box cover is closed, the insulator enters the interior of the box body. By retracting and extending the chain plate through the telescopic rod, the height of the insulator in the box body is adjusted. On the one hand, it reduces the requirement for the volume of the liquid in the box body. On the other hand, it can make the insulator hang at the middle position of the liquid, improving the boiling water effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0041] Embodiment 1 This embodiment provides an insulator boiling test device, and this test device includes a boiling water tank 1, an automatic loading and unloading mechanism, and a console for controlling the actions of each driver, as Figures 1-12 shown.

[0042] The boiling water tank 1 includes a box body 101 with an opening at the top, a box cover 102 and several partition plates 103. A plurality of heating resistance wires 104 are evenly arranged on the bottom side inside the box body 101. The several partition plates 103 are evenly distributed inside the box body 101 along the axial direction of the box body 101. The bottom of each partition plate 103 is rotatably connected to the box body 101 through a first hinge shaft 105. The several partition plates 103 are each driven by a gear drive assembly 5 to rotate around the first hinge shaft 105 to lift between a horizontal position and a vertical position, and are hermetically connected to the box body 101 through a sealing connection assembly 6 to divide the box body 101 into several boiling water tanks.

[0043] In this embodiment, the gear drive assemblies 5 are arranged in pairs on both sides of the corresponding partition plate 103. Gear mounting grooves 507 for mounting the gear drive assemblies 5 are formed in the inner wall of the box body 101, and the gear drive assemblies 5 are arranged in the gear mounting grooves 507. The gear drive assembly 5 includes a ring gear 501, a planetary gear 502 and a sun gear 503. The sun gear 503 is rotatably mounted on the box body 101 and is driven to rotate by a first rotary driver 504. The first rotary driver 504 is mounted on the inner wall of the gear mounting groove 507, and the rotating end of the first rotary driver 504 is coaxially connected to the sun gear 503. The ring gear 501 is sleeved outside the sun gear 503 and is fixedly mounted on the box body 101. The planetary gear 502 is arranged between the sun gear 503 and the ring gear 501. Both sides of the planetary gear 502 are meshed and connected to the sun gear 503 and the ring gear 501 respectively. The planetary gear 502 is movably mounted on the side wall of the partition plate 103 through a third slider 505. A chute 506 matching the third slider 505 is formed in the partition plate 103. The third slider 505 is movably mounted in the chute 506. The planetary gear 502 is rotatably mounted on the third slider 505 through a wheel shaft. One end of the wheel shaft is connected to the third slider 505, and the other end passes through the opening of the gear mounting groove 507 and enters the gear mounting groove 507 to be rotatably connected to the planetary gear 502. The opening of the gear mounting groove 507 forms a channel for the wheel shaft to move synchronously with the rotation of the planetary gear 502.

[0044] The gear drive assembly 5 cooperates with each other through the ring gear 501, the planetary gear 502 and the sun gear 503. The sun gear 503 drives the planetary gear 502 to rotate. The planetary gear 502 drives the partition plate 103 to rotate around the first hinge shaft 105 through the third slider 505. The third slider 505 slides in the chute 506 to realize the smooth switching between the horizontal state and the vertical state of the partition plate 103. When the third slider 505 moves with the planetary gear 502 to be in the same plane as the first hinge shaft 105 of the partition plate 103, the partition plate 103 is in the horizontal state. When the third slider 505 moves with the planetary gear 502 to be directly above the first hinge shaft 105 of the partition plate 103, the partition plate 103 is in the vertical state. When the sun gear 503 stops rotating, the planetary gear 502 is braked through the cooperation of the ring gear 501 and the sun gear 503, so that the partition plate 103 maintains the corresponding state unchanged.

[0045] In this embodiment, the sealed connection assembly 6 includes a sealing frame 601 and a wedge block 602. The sealing frame 601 has a U-shaped structure. The two sides and the bottom of the sealing frame 601 respectively correspond to the two side edges and the bottom edge of the partition plate 103. The sealing frame 601 is vertically installed in the box body 101. The outer edge of the sealing frame 601 is hermetically welded to the inner wall of the box body 101. A first sealing strip is provided on one side wall of the sealing frame 601 close to the corresponding partition plate 103. Two connecting plates 604 are provided on one side of the top of the partition plate 103 close to the sealing frame 601. Two connecting grooves are formed on the top surface of the sealing frame 601 for the connecting plates 604 to rotate into or out of along with the partition plate 103. The wedge blocks 602 correspond to the respective connecting plates 604 one by one. The wedge blocks 602 are movably installed on the sealing frame 601 through extension frames 603 and are driven to move linearly by a first linear driver 605. The extension frames 603 are installed on the side of the sealing frame 601 away from the partition plate 103. The first linear driver 605 is installed on the extension frame 603. The wedge blocks 602 are installed at the telescopic ends of the first linear driver 605. Through grooves for the wedge blocks 602 to insert are formed on the connecting plates 604. When the connecting plates 604 move into the connecting grooves along with the partition plate 103, the wedge blocks 602 are pushed by the first linear driver 605 to move into the through grooves, and the partition plate 103 is driven by the connecting plates 604 to press on the first sealing strip.

[0046] Through the mutual cooperation of the sealing frame 601, the connecting plates 604 and the wedge blocks 602 of the sealed connection assembly 6, when the partition plate 103 is driven by the gear drive assembly 5 to rotate to the vertical position, the wedge blocks 602 utilize their own shape characteristics to insert into the through grooves of the connecting plates 604, so that the partition plate 103 is tightly pressed on the first sealing strip of the sealing frame 601, realizing the sealed connection between the partition plate 103 and the sealing frame 601, and further making the water boiling tanks on both sides of the partition plate 103 independent of each other.

[0047] Each water boiling tank corresponds to a tank cover 102. The tank cover 102 covers the opening of the box body 101. A second sealing strip matching the tank cover 102 is provided on the top surface of the box body 101. One side of the tank cover 102 is hinged to the box body 101 through a first hinge 106, and the other side is detachably connected to the box body 101 through a locking assembly 7.

The two Z-shaped side plates 902 are symmetrically installed on the top surface of the bottom plate 903 and cooperate with the bottom plate 903 to form an inverted T-shaped groove. A guiding groove 904 matching the two rollers 901 is formed on the top surface of the bottom plate 903 in the inverted T-shaped groove and on the bottom surface of the Z-shaped side plate 902. The rotating arm 801 is arranged between the two Z-shaped side plates 902, and the two rollers 901 are respectively rotatably installed in the corresponding guiding grooves 904.

[0052] The rotating arm 801 is movably connected to the box cover 102 through the roller assembly 9 and cooperates with the first hinge 106 on one side of the box cover 102, so that one side of the box cover 102 is fixed in position, and the angle of the box cover 102 is adjusted by rotating the other side, realizing rapid adjustment of the angle of the box cover 102 with high position accuracy.

Each water boiling tank corresponds to at least two insulator fixing assemblies 10. The insulator fixing assemblies 10 are installed on the bottom surface of the box cover 102 corresponding to the water boiling tank and rotate into or out of the box body 101 along with the box cover 102. The loading conveyor belt 3 and the unloading conveyor belt 4 are arranged on the same side of the box body 101. The insulator moving and transferring assembly 2 is arranged between the loading conveyor belt 3 and the box body 101 and moves the insulators to be tested on the loading conveyor belt 3 to the insulator fixing assembly 10. The insulator moving and transferring assembly 2 is arranged between the unloading conveyor belt 4 and the box body 101 and moves the insulators that have completed the test at the insulator fixing assembly 10 to the unloading conveyor belt 4.

[0054] In this embodiment, the insulator fixing assembly 10 includes a fixing rod 1001, a chain plate 1002 that can be bent and flattened, and a telescopic rod 1003. The fixed end of the telescopic rod 1003 is hinged to the bottom surface of the box cover 102. The telescopic rod 1003 is driven by a third linear driver 1007 to rotate close to or away from the chain plate 1002 between a first position and a second position.

The telescopic end of the telescopic rod 1003 has an arc-shaped hook body 1004.

[0055] The fixed rod 1001 is vertically and fixedly installed on the bottom surface of the box cover 102, on the side of the telescopic rod 1003 close to the first hinge 106; one end of the chain plate 1002 in the length direction is fixedly connected to the fixed rod 1001, and the fixed rod 1001, the chain plate 1002, and the telescopic rod 1003 are in the same vertical plane. The chain plate 1002 includes a plurality of flat plates 10021 sequentially distributed along the length direction of the chain plate 1002. Adjacent two flat plates 10021 are hinged by a second hinge shaft 10022. On the side of each flat plate 10021 away from the telescopic rod 1003, a limiting tip 10023 extends along the length direction of the chain plate 1002. When the top surface of the limiting tip 10023 abuts against the adjacent flat plate 10021, the chain plate 1002 is in a flattened state and is in the same plane as the fixed rod 1001. On the side of the chain plate 1002 close to the fixed rod 1001, an insulator limiting plate 1006 is fixedly provided. The insulator limiting plate 1006 is arranged on the side of the chain plate 1002 close to the telescopic rod 1003, and the end of the insulator limiting plate 1006 close to the telescopic rod 1003 bends towards the side away from the fixed rod 1001. On the side of the chain plate 1002 away from the fixed rod 1001, an ear plate 1005 detachably connected to the arc-shaped hook body 1004 of the telescopic rod 1003 is provided, and a connection hole for the arc-shaped hook body 1004 to pass through is opened on the ear plate 1005.

[0056] Through the mutual cooperation of the chain plate 1002 and the telescopic rod 1003, and the mutual cooperation of the arc-shaped hook body 1004 at the end of the telescopic rod 1003 and the ear plate 1005, the insulator fixing assembly 10 realizes detachable connection with the end of the chain plate 1002. When the telescopic rod 1003 is connected to the chain plate 1002, the chain plate 1002 and the telescopic rod 1003 respectively limit the upper and lower sides of the insulator. Due to the structural characteristics of the umbrella skirt of the insulator itself, it can be axially limited between two insulator fixing assemblies 10, thereby realizing the relative fixation between the insulator and the box cover 102.

[0057] In this embodiment, the insulator moving and transferring assembly 2 includes an insulator support frame 201, a lifting structure, a longitudinal moving structure, and a lateral moving structure. There are two insulator support frames 201, which are arranged in parallel.

Each insulator support frame 201 has an insulator support groove at the top. The lifting structure includes a lifting plate 202 and an intermediate plate 203. The two insulator support frames 201 are installed on the top surface of the lifting plate 202.

[0058] The longitudinal moving structure includes a moving seat 207, a first slider 208, and a first guide rail 209. The first guide rail 209 is horizontally installed on the top surface of the moving seat 207 and is perpendicular to the length direction of the box body 101. The first slider 208 is slidably installed on the first guide rail 209. The intermediate plate 203 is installed on the top of the first slider 208. The first slider 208 is driven by a fourth linear actuator 210 to move along the first guide rail 209, driving the lifting structure and the insulator support frame 201 to move synchronously. The lateral moving structure includes a second slider 211 and a second guide rail 212. The second guide rail 212 is arranged below the moving seat 207 and is parallel to the length direction of the box body 101. The second slider 211 is installed on the bottom surface of the moving seat 207 and is slidably connected to the second guide rail 212. The second slider 211 is driven by a fifth linear actuator 213 to move along the second guide rail 212, driving the longitudinal moving structure, the lifting structure, and the insulator support frame 201 to move synchronously.

[0059] The insulator support frame 201 realizes the functions of lifting, longitudinal movement, and lateral movement through the lifting structure, the longitudinal moving structure, and the lateral moving structure, realizes the automatic switching of positions among the loading conveyor belt 3, the boiling water tank 1, and the unloading conveyor belt 4, and automatically adjusts the support height during loading and unloading.

[0060] In this embodiment, to ensure the automatic loading and unloading of insulators, improve safety, and prevent operation failures, the insulator water boiling tank test device further includes a sensor assembly; the sensor assembly includes a first sensor for detecting whether the chain plate 1002 is flattened in place, a third sensor for detecting whether the insulator rolls to reach the insulator limit plate 1006, a fourth sensor for detecting whether the insulator enters the insulator support groove, a fifth sensor for detecting the liquid level height in the box body 101, and a scanning identifier for scanning the information two-dimensional code of the insulator. In this embodiment, both the first sensor and the third sensor adopt position sensors. The first sensor is installed on the moving seat 207, and the third sensor is installed on the insulator limit plate 1006. The fourth sensor adopts a gravity sensor and is installed in the insulator support groove. The fifth sensor adopts a liquid level sensor and is installed on the inner wall of the box body 101.

The lower outlets of the two condenser tubes 11 of the same water boiling tank are interconnected through a second pipeline 1103. The second pipeline 1103 is connected to the inside of the box body 101 through a second hose 1104. The bottom air inlets of each condenser tube 11 are respectively connected to the inside of the box body 101 through an air inlet bellows 1105. The arrangement of the condenser tubes 11 ensures the steam condensation and reflux of each water boiling tank, reduces liquid loss and temperature dissipation. Even if one of the condenser tubes 11 is damaged, the other condenser tube 11 can still play the condensation role.

[0062] In this embodiment, each rotary driver and linear driver adopt components with waterproof functions and corresponding rotary or linear driving functions. For example, the rotary driver adopts a waterproof motor, and the linear driver adopts a waterproof oil cylinder or a waterproof air cylinder.

[0063] Embodiment 2 This embodiment provides a method for conducting a water boiling test on insulators using the insulator water boiling test device of Embodiment 1. The entire test process is realized by the console controlling each driver and the telescopic rod 1003 according to the feedback signals of each sensor. The test method includes the following steps: Step 1, insulator transfer: The console controls to move the insulator support frame 201 to the material receiving position of the feeding conveyor belt 3 in advance. The two insulator support frames 201 are respectively located on both sides of the feeding conveyor belt 3 and below the top surface of the feeding conveyor belt 3. The insulator to be tested is transported and moved to the material receiving position by the feeding conveyor belt 3. The feeding conveyor belt 3 stops transporting, and the two insulator support frames 201 rise. After the fourth sensor detects that the insulator to be tested enters the insulator support groove of the insulator support frame 201, the scanning and recognition device scans the QR code of the insulator to be tested to obtain the size information of the insulator to be tested; The console allocates the boiling position according to the size information of the insulator to be detected and the usage of the boiling tanks in the boiling water tank 1, and controls the drivers of the gear drive assembly 5 and the sealed connection assembly 6 to adjust the positions of the partition plates 103 covered by the boiling position, ensuring that the partition plates 103 at both ends of the boiling position are in a vertical sealed state, and the partition plates 103 in the middle are in a horizontal state so that the boiling tanks in the boiling position are interconnected.

[0064] Step 2, insulator feeding: The console controls the drivers of the insulator moving and transferring assembly 2 to move the insulator support frame 201 and the insulator to be tested to the feeding position corresponding to the boiling position. Then, the insulator support frame 201 rises to lift the insulator to be tested to a preset height. The console controls the drivers of the locking assembly 7 and the lifting assembly 8 to rotate the lids 102 of the boiling position to a semi-open and inclined state, with an included angle of 70° between each lid 102 and the horizontal plane. The console controls the drivers of the insulator fixing assembly 10 to make the telescopic end of the telescopic rod 1003 extend obliquely downward to the lower part of the insulator to be tested. During the downward extension of the telescopic end of the telescopic rod 1003, the chain plate 1002 gradually unfolds obliquely downward under the action of gravity as the telescopic rod 1003 extends to the lower part of the insulator to be tested; After the first sensor detects that the link plate 1002 is flattened in place, the telescopic end of the telescopic rod 1003 continues to extend forward to disengage the arc-shaped hook body 1004 from the ear plate 1005 of the link plate 1002. After the telescopic rod 1003 rotates away from the link plate 1002, the telescopic end retracts. The box cover 102 rotates to the vertical state and is fully opened. At this time, the link plate 1002 is in a horizontal state. The insulator support frame 201 descends. The insulator to be tested descends onto the link plate 1002 and is supported jointly by the insulator support frame 201 and the link plate 1002. The telescopic rod 1003 acts to extend the telescopic end above the insulator to be tested and extend the arc-shaped hook plate to the side of the ear plate 1005 of the link plate 1002 away from the insulator to be tested. The telescopic end of the telescopic rod 1003 retracts to pass the arc-shaped hook plate through the connection hole of the ear plate 1005 of the link plate 1002, realizing the connection between the telescopic rod 1003 and the link plate 1002. After that, the insulator support frame 201 descends, and the insulator to be tested is limited between the link plate 1002 and the telescopic rod 1003, completing the feeding. At this time, the link plate 1002 supports at the bottom of the insulator column of the insulator, and the telescopic rod 1003 is above the insulator column of the insulator, as Figure 9 shown.

[0065] Step 3: Boiling water test: The console controls each driver of the insulator fixing assembly 10. The telescopic end of the telescopic rod 1003 retracts to pull the link plate 1002 to turn and bend. The link plate 1002 pushes the insulator to be tested to roll and move closer to the box cover 102. When the third sensor detects that the insulator to be tested reaches the insulator limit plate 1006, the telescopic end of the telescopic rod 1003 stops retracting, as Figure 10 shown. Control each driver of the lifting assembly 8, and the box covers 102 at the boiling water position rotate downward and close synchronously. The insulator fixing assembly 10 and the insulator to be tested rotate into the box body 101 along with the box cover 102. The console controls the telescopic end of the telescopic rod 1003 to extend downward according to the liquid level height of the box body 101 detected by the fifth sensor. The link plate 1002 extends downward under its own gravity and the gravity of the insulator to be tested, so that the insulator to be tested moves downward below the liquid level, and then the telescopic rod 1003 stops acting, and the boiling water test starts. During the boiling water test, the heating resistance wire 104 is used to heat the inside of the box body 101, and the steam return is carried out by using the condenser pipe 11; Step 4. Insulator blanking: After the water boiling is completed, the console controls the retraction of the telescopic end of the telescopic rod 1003, and the tested insulator moves upward. When the third sensor detects that the tested insulator reaches the insulator limit plate 1006, the telescopic end of the telescopic rod 1003 stops retracting. Control the drivers of the locking assembly 7 and the lifting assembly 8 to rotate each lid 102 at the water boiling position to the inclined half-open state. The telescopic end of the telescopic rod 1003 extends obliquely downward. During the extension process, the chain plate 1002 gradually unfolds obliquely downward under the action of its own gravity and the gravity of the tested insulator as the telescopic end of the telescopic rod 1003 extends. The tested insulator rolls obliquely downward along the chain plate 1002. When the first sensor detects that the chain plate 1002 is flattened in place, control the drivers of the insulator moving and transferring assembly 2 to raise the insulator support frame 201 close to the tested insulator. When the fourth sensor detects that the tested insulator enters the insulator support groove of the insulator support frame 201, the telescopic end of the telescopic rod 1003 continues to extend forward to separate the arc-shaped hook body 1004 from the ear plate 1005 of the chain plate 1002. After the telescopic rod 1003 rotates away from the chain plate 1002, the telescopic end retracts. The insulator support frame 201 rises to move the tested insulator away from the chain plate 1002. The telescopic rod 1003 acts to extend the telescopic end above the insulator to be tested and extend the arc-shaped hook plate to the side of the ear plate 1005 of the chain plate 1002 away from the insulator to be tested. The telescopic end of the telescopic rod 1003 retracts to pass the arc-shaped hook plate through the connection hole of the ear plate 1005 of the chain plate 1002. After the arc-shaped hook body 1004 is connected to the ear plate 1005 of the chain plate 1002, the telescopic end of the telescopic rod 1003 retracts to pull the chain plate 1002 to flip and bend away from the feeding position, completing the blanking; Step 5. Insulator removal: Control the drivers of the insulator moving and transferring assembly 2. After the insulator support frame 201 descends and moves, it drives the tested insulator to move above the blanking conveyor belt 4. The insulator support frame 201 descends to place the tested insulator on the blanking conveyor belt 4, and the blanking conveyor belt 4 conveys and removes the tested insulator.

[0066] The test method of this embodiment utilizes the link plate 1002 and the telescopic rod 1003 in the insulator fixing assembly. Through the reasonable layout of the feeding position and the position where the box cover is opened, the link plate 1002 provides power by its own gravity and is limited by the arc-shaped hook body at the end of the telescopic rod 1003, realizing the automatically flattening of the link plate 1002 with controllable speed. It cooperates with the insulator support frame 201 to optimize the support height in each process of the insulator support frame 201, achieving the automatic loading and unloading of insulators. In the water boiling test stage, the telescopic rod 1003 drives the link plate to push the insulator to be tested to move as close as possible to the box cover 102. On the one hand, it reduces the requirement for the width dimension of the top opening of the box body 101. On the other hand, it reduces the torque exerted by the insulator on the box cover 102 and reduces the load-bearing of the box cover and the lifting assembly. After the box cover is closed, the insulator enters the interior of the box body. By retracting and extending the link plate 1002 through the telescopic rod 1003, the height of the insulator in the box body is adjusted. On the one hand, it reduces the requirement for the volume of the liquid in the box body. On the other hand, it can make the insulator hang at the middle position of the liquid, improving the water boiling effect.

10. The test method of the insulator boiling water test device according to any one of claims 1-9, characterized in that: The test method includes: Step 1. Insulator transfer: The console controls to move the insulator support frame to the material receiving position of the feeding conveyor belt in advance. The insulator to be tested is conveyed and moved by the feeding conveyor belt. When the fourth sensor detects that the insulator to be tested enters the insulator support groove of the insulator support frame, the scanning identifier scans the QR code of the insulator to be tested to obtain the size information of the insulator to be tested. The console distributes the boiling positions according to the size information of the insulator to be detected and in combination with the usage of the boiling tanks in the boiling box, and controls the drivers of the gear drive assembly and the sealed connection assembly to adjust the positions of the partitions covered by the boiling positions to ensure that the partitions at both ends of the boiling position are in a vertical sealed state and the middle partition is in a horizontal state so that the boiling tanks in the boiling position are communicated with each other; Step 2. Insulator loading: The console controls the drivers of the insulator moving and transfer assembly to move the insulator support frame and the insulator to be tested to the loading position corresponding to the boiling position. After that, the insulator support frame is raised to lift the insulator to be tested to the set height. Then, the console controls the drivers of the locking assembly and the lifting assembly to rotate the lids of each box at the boiling position to the inclined semi-open state. Next, the console controls the drivers of the insulator fixing assembly to make the telescopic end of the telescopic rod extend obliquely downward to the lower part of the insulator to be tested. At the same time, under the action of gravity, the chain plate gradually unfolds obliquely downward as the telescopic rod extends. When the first sensor detects that the chain plate is flattened in place, the telescopic end of the telescopic rod continues to extend forward to disengage the arc-shaped hook body from the chain plate ear plate. Then, the telescopic rod rotates away from the chain plate and the telescopic end retracts. The lid rotates to the vertically open state. The insulator support frame descends, and the insulator to be tested descends onto the chain plate and is supported by the insulator support frame and the chain plate together. The telescopic rod moves, making the telescopic end extend above the insulator to be tested. After the arc-shaped hook plate is connected to the chain plate ear plate, the insulator support frame descends, and the insulator to be tested is limited between the chain plate and the telescopic rod, completing the loading; Step 3. Boiling test: The console controls the drivers of the insulator fixing assembly. The telescopic end of the telescopic rod retracts to pull the chain plate to flip and bend. The chain plate pushes the insulator to be tested to move closer to the lid. When the third sensor detects that the insulator to be tested reaches the insulator limit plate, the telescopic end of the telescopic rod stops retracting. Then, the console controls the drivers of the lifting assembly to rotate the lids of each box at the boiling position downward to close. The insulator fixing assembly and the insulator to be tested rotate into the box with the lid. The console controls the telescopic end of the telescopic rod to extend downward according to the liquid level height of the box detected by the fifth sensor, so that the insulator to be tested moves downward below the liquid level and the boiling test begins; Step 4. Insulator unloading: After the boiling is completed, the console controls the telescopic end of the telescopic rod to retract, and the tested insulator moves upward. When the third sensor detects that the tested insulator reaches the insulator limit plate, the telescopic end of the telescopic rod stops retracting. Then, the console controls the drivers of the locking assembly and the lifting assembly to rotate the lids of each box at the boiling position to the inclined semi-open state. The telescopic end of the telescopic rod extends obliquely downward. During the extension process, under the action of its own gravity and the gravity of the tested insulator, the chain plate gradually unfolds obliquely downward as the telescopic end of the telescopic rod extends. The tested insulator rolls downward along the chain plate. When the first sensor detects that the chain plate is flattened in place, the console controls the drivers of the insulator moving and transfer assembly to raise the insulator support frame closer to the tested insulator. When the fourth sensor detects that the tested insulator enters the insulator support groove of the insulator support frame, the telescopic end of the telescopic rod continues to extend forward to disengage the arc-shaped hook body from the chain plate ear plate. Then, the telescopic rod rotates away from the chain plate and the telescopic end retracts. The insulator support frame rises to move the tested insulator away from the chain plate. The telescopic rod moves, and after the arc-shaped hook body is connected to the chain plate ear plate, the telescopic end of the telescopic rod retracts to pull the chain plate to flip and bend away from the loading position, completing the unloading; Step 5, insulator removal: Control each driver of the insulator moving and transferring assembly. After the insulator support frame descends and moves, it drives the tested insulator to move above the blanking conveyor belt. The insulator support frame moves downward to place the tested insulator on the blanking conveyor belt, and the blanking conveyor belt conveys and removes the tested insulator.
