Description

Technical Field

[0001] The invention relates to the technical field of electric power installation engineering, and in particular to a withstand voltage test device for electric power installation. Background Art

[0002] Insulating boots are the protective equipment that power workers must wear in power installation projects. After a period of use, the insulation performance of insulating boots will change. Therefore, in order to ensure the safety of power workers, it is necessary to regularly conduct voltage resistance tests on insulating boots to detect the insulation degree of insulating boots.

[0003] The entire test operation process of the existing pressure test equipment on the market requires manual installation, placement, docking and other operations. For example, first, the insulating boots to be tested are placed in a pressure barrel, and then water is injected into the pressure barrel and the insulating shoes respectively. Then, the inner electrode connected to the operation box is placed in the insulating boots, and the outer electrode is placed in the pressure barrel, and then the power is turned on for testing. This kind of test operation process will greatly affect the test efficiency and the operation is time-consuming and laborious when facing a large number of objects to be tested; and if leakage occurs during manual operation, there will be great safety hazards. Therefore, the present invention was born. Summary of the invention

[0004] The purpose of the present invention is to provide a voltage withstand test device for power installation, which can reduce the workload of human intervention in the test operation process, thereby reducing the manual workload, improving the test efficiency and avoiding existing safety hazards.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a voltage withstand test device for power installation, including an operation box, which is configured to perform power-on detection; an inner conductive plug, which is configured to be connected to the operation box; an outer conductive sheet, which is configured to be connected to the operation box; and also includes: an expansion component, which is configured to cooperate with an insulating boot and is used to expand the boot opening of the insulating boot; a feeding component, which is configured to transmit the insulating boot to be tested and realize the output of the insulating boot in a vertically placed state; a voltage withstand tank, which is configured to receive the insulating boot output by the feeding component and is connected to the outer conductive sheet; a water inlet pipe, which is configured to inject water into the insulating boot; a docking component, which is configured to cooperate with the expansion component to form a detachable docking; a moving component, which is configured to drive the docking component to drive the insulating boot in the voltage withstand tank to move between a test position and an output position; a linkage member, which is configured to constitute a linkage between the inner conductive plug and the moving component and is used to control the inner conductive plug to enter and exit the insulating boot in the voltage withstand tank; a feeding component, which is configured to cooperate with the docking component to realize the separation of the docking component and the expansion component at the output position.

[0006] By adopting the above technical solution, an expansion component is installed at the opening of the insulating boot to be tested to open the opening, and then the insulating boot is horizontally placed on the feeding component for transmission. Under the action of the feeding component, the insulating boot switches from a horizontal placement state to a vertical placement state and enters the pressure tank, and then water is injected into the insulating boot through the set water inlet pipe. Then the moving component drives the docking component to move from the output position to the test position and docks with the expansion component on the insulating boot located in the pressure tank. During the movement, the moving component is linked with the inner conductive plug rod through the set linkage component to drive the inner conductive plug rod to be inserted into the insulating boot located in the pressure tank, and then the power is turned on to complete the test.

[0007] After the test is completed, the moving component cooperates with the docking component to drive the insulating boots that have completed the test to leave the pressure cell and move from the test position to the output position. During the movement, the moving component drives the inner conductive plug rod to leave the inside of the insulating boots through the provided linkage components to avoid mutual interference in the structure. The insulating boots that move to the output position are separated from the docking component and the expansion component by the action of the blanking component, and then the blanking and separation of the insulating boots are achieved after the test is completed, and the test operation of the insulating boots is completed in this cycle. The above structure is used to reduce the workload of human intervention in the test operation process, thereby reducing the manual workload, improving the test efficiency and avoiding the existing safety hazards.

[0008] It is further configured as follows: the feeding assembly includes a feeding stroke and a reversing output stroke connected to the feeding stroke and used to realize output of the insulating boot in a vertically placed state, and the water inlet pipe is arranged above the movement path of the reversing output stroke.

[0009] By adopting the above technical solution, the insulating boots to be tested are placed horizontally in the feeding stroke. When the insulating boots are transmitted from the feeding stroke to the reversing output stroke, the position of the insulating boots is changed under the action of the reversing output stroke, and the insulating boots are switched from a horizontal placement state to a vertical placement state and output into the pressure tank. The setting structure enables the insulating boots to complete the water injection operation in the reversing output stroke stage, and the weight of the insulating boots is increased by water injection, so that the insulating boots can enter the pressure tank more stably to offset the buoyancy of the water in the pressure tank on the insulating boots, thereby improving the feasibility and transmission reliability of the structure.

[0010] It is further configured as follows: the expansion assembly includes an expansion plug body, a detection port arranged on the expansion plug body and for the inner conductive plug rod to pass through, and a fixing clamp distributed around the outer peripheral wall of the expansion plug body and used to clamp the opening of the insulating boot; the expansion plug body is provided with a drainage channel, and when the insulating boot with the expansion assembly is in the reversing output stroke, the orthographic projections at both ends of the drainage channel correspond to the output path of the water inlet pipe and the inner cavity of the insulating boot respectively.

[0011] By adopting the above technical solution, the expansion plug is inserted into the opening of the insulating boot, and then the fixed clamp is used to fix the expansion plug and the insulating boot; and the drainage channel is provided to enable the water flow output by the water inlet pipe to enter the inner cavity of the insulating boot more smoothly, thereby improving the feasibility of the setting method.

[0012] It is further configured as follows: the moving component drives the docking component to move, and has a docking stroke in which it moves toward the pressure-resistant pool and docks with the expansion component, and a leaving stroke in which the insulating boot is driven to leave the pressure-resistant pool through the docking component. The linkage component includes a linkage component that links the moving component with the inner conductive rod, and a guide component that guides the movement of the inner conductive rod. When the docking component is in the docking stroke, the inner conductive rod is driven by the linkage component to be inserted into the insulating boot located in the pressure-resistant pool; when the docking component is in the leaving stroke, the inner conductive rod is driven to leave the insulating boot through the guide component.

[0013] By adopting the above technical solution, the linkage component is used to form the linkage between the moving component and the inner conductive plug rod, and the guide component is provided to realize the inner conductive plug rod entering the inner cavity of the insulating boot during the linkage process, so as to achieve the purpose of linkage control. This setting method makes it unnecessary to set an external driving source for the control of the inner conductive plug rod, and the pure mechanical linkage structure is more reliable and has lower cost.

[0014] It is further configured as follows: the moving component includes a moving frame, a moving seat slidably arranged on the moving frame in a horizontal direction, a horizontal screw rod rotatably arranged on the moving frame and threadedly connected to the moving seat, a moving motor driving the horizontal screw rod to rotate, a lifting block slidably arranged on the moving seat, and a lifting cylinder driving the lifting block to move up and down, and the docking component is arranged on the lifting block.

[0015] By adopting the above technical solution, the mobile motor cooperates with the horizontal screw to drive the mobile seat to move horizontally, and then cooperates with the set lifting cylinder to drive the lifting block to move vertically to realize the switching of spatial position and achieve the purpose of movement.

[0016] It is further configured as follows: the docking assembly includes a magnetic block fixedly arranged at the bottom of the lifting block and an iron sheet fixedly arranged at the expansion assembly and adsorbed by the magnetic block.

[0017] By adopting the above technical solution, the magnetic block cooperates with the iron sheet to realize the detachable docking operation between the lifting block and the expansion support assembly, which has a simple structure and low cost.

[0018] It is further configured as follows: the linkage component includes a linkage inner seat slidably arranged on the mobile seat along the movement direction of the lifting block, a linkage outer seat slidably arranged on the linkage inner seat perpendicular to the movement direction of the mobile seat, a one-way linkage plate hinged to the lifting block, a limit block arranged on the lifting block and located on the upper side of the rotation direction of the one-way linkage plate, a tightening torsion spring driving the one-way linkage plate to press against the limit block, and a reset spring driving the linkage inner seat to move away from the pressure-resistant pool, the one-way linkage plate presses against the linkage outer seat to drive it to move downward, and the inner conductive plug is arranged on the linkage outer seat.

[0019] By adopting the above technical solution, the torsion spring drives the one-way linkage plate to press against the limit block, so that the one-way linkage plate is kept horizontal to drive the linkage outer seat to drive the inner conductive plug rod to move downward toward the pressure-resistant tank, and cooperate with the reset spring to drive the inner conductive plug rod to move upward to achieve the purpose of linkage reciprocation. When the linkage outer seat is located above the one-way linkage plate, the one-way rotation structure of the one-way linkage plate enables the linkage outer seat to drive the one-way linkage plate to rotate downward and then pass the one-way linkage plate to the bottom of the one-way linkage plate, and the elastic force of the torsion spring is smaller than the reset spring.

[0020] It is further configured as follows: the guide assembly includes a guide groove and a check block arranged on the moving seat, a part of the linkage outer seat is slidably arranged in the guide groove, the guide groove includes a vertically arranged insertion section and a reset section whose two ends are connected to the insertion section, the check block is hinged at the intersection of the lower end of the reset section and the insertion section and guides the linkage outer seat from the insertion section to enter the reset section, when the linkage outer seat is located in the insertion section, the linkage outer seat and the one-way linkage plate form a linkage; when the linkage outer seat is located in the reset section, the linkage outer seat is separated from the one-way linkage plate, the inner conductive plug rod is slidably arranged on the linkage outer seat along the movement direction of the lifting block and a tightening spring is connected between the two.

[0021] By adopting the above technical solution, when the linkage outer seat is located in the insertion section, the position of the linkage outer seat against the one-way linkage plate is located on the movement path of the one-way linkage plate, so that the one-way linkage plate can resist the linkage outer seat to drive the inner conductive plug rod to move downward. When the linkage outer seat moves upward through the check block, the linkage outer seat enters the reset section from the insertion section under the action of the check block, and the position of the linkage outer seat against the one-way linkage plate is located on one side of the movement path of the one-way linkage plate, so that the top of the linkage outer seat is not blocked by the one-way linkage plate, and then under the action of the reset spring, the inner conductive plug rod can be driven to move upward and return from the reset section to the insertion section. Then the lifting block drives the one-way linkage plate to move upward, and through the one-way rotation structure of the one-way linkage plate, the linkage outer seat can drive the one-way linkage plate to rotate downward and then pass the one-way linkage plate to the bottom of the one-way linkage plate; and when the linkage outer seat returns from the reset section to the insertion section, the reset spring is in a state of no force. By setting the inner conductive plug rod as a floating structure and cooperating with the tightening spring, the stable contact between the inner conductive plug rod and the water body in the insulating boot is ensured.

[0022] It is further configured as follows: the unloading component includes a unloading rack, a unloading channel formed on the unloading rack, a qualified storage slot and an unqualified storage slot arranged below the unloading channel, a swing arm rotatably arranged on the unloading rack, a unloading motor driving the swing arm to rotate, and a qualified hook rod and an unqualified hook rod arranged on the swing arm and corresponding to the qualified storage slot and the unqualified storage slot above them respectively.

[0023] By adopting the above technical solution, when the insulating boots are qualified products, the unloading motor drives the swing arm to swing and lift the position height of the qualified hook rod, and then the moving assembly cooperates with the docking assembly to drive the insulating boots through the unloading channel to be hooked by the qualified hook rod, thereby realizing the separation of the docking assembly and the expansion assembly, so that the qualified insulating boots fall into the qualified storage slot located below the qualified hook rod. Similarly, the operation for unqualified insulating boots is the same as above.

[0024] It is further configured that: when the linkage outer seat moves from the reset section to the insertion section position, the horizontal height of the inner conductive insertion rod is located above the highest point of the qualified hook rod and the unqualified hook rod.

[0025] By adopting the above technical solution, this setting structure can avoid the contact between the inner conductive plug rod and the hook rod when the moving component drives the inner conductive plug rod to move toward the blanking component, thereby protecting the inner conductive plug rod.

[0026] In summary, the present invention has the following beneficial effects: the present invention can reduce the workload of human intervention in the test operation process, thereby reducing manual workload, improving test efficiency and avoiding existing safety hazards.
