Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, specifically relating to a quick cleaning device for contamination on the surface of insulator strings in power equipment. Background Technology

[0002] Insulator strings are the core insulating components of substation equipment, primarily responsible for electrical insulation, conductor suspension, and mechanical support. Their insulation performance directly determines the operational stability and power supply reliability of the substation transmission system. Regular and efficient cleaning and maintenance of insulator strings is of paramount importance in substation equipment operation and maintenance.

[0003] Currently, the power operation and maintenance industry employs various methods for cleaning insulator strings of substation equipment. Mainstream methods include manual wiping, high-pressure water washing, dry ice cleaning, and automated robotic cleaning. However, each method has significant technical shortcomings in practical application. Manual wiping, a traditional method, is labor-intensive and time-consuming. Furthermore, due to the varying shapes (diameters) of insulator strings, both manual wiping and high-pressure water washing require constant angle adjustments, resulting in poor cleaning effectiveness and low efficiency. Dry ice cleaning and automated robotic cleaning, on the other hand, suffer from high equipment purchase and maintenance costs and complex procedures, making them difficult to widely apply to the daily operation and maintenance of small and medium-sized substations. Therefore, there is an urgent need for a rapid cleaning device for the surface contamination of substation insulator strings to solve these technical problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick cleaning device for contamination on the surface of insulator strings in power equipment, including a pull rod; the pull rod is equipped with a cleaning assembly, which includes a fixed ring, connecting blocks, and cleaning brushes. The fixed ring is disposed on the pull rod, and multiple connecting blocks are evenly distributed along the circumference of the inner ring of the fixed ring. Multiple cleaning brushes are respectively hinged to the corresponding connecting blocks through hinge shafts, and the bristles of the multiple cleaning brushes face the center of the fixed ring.

[0005] By installing a cleaning brush that can rotate in both directions around the hinge axis on the inner ring surface of the fixed ring, when cleaning the surface of the insulator string, the fixed ring is fitted onto one end of the insulator string, and the pull rod is pulled to make the fixed ring reciprocate on the insulator string. During the movement, the cleaning brush rotates continuously around the hinge axis as the shape (diameter) of the insulator string changes, so that the fixed ring can slide smoothly on the insulator string while the bristles of the cleaning brush clean the surface of the insulator string.

[0006] Preferably, a torsion spring is provided on the hinge shaft. The torsion spring can apply a reverse force when the cleaning brush rotates around the hinge shaft, increasing the pressure between the bristles and the surface of the insulator string, thereby making the contact between the bristles of the cleaning brush and the surface of the insulator string more effective and improving the cleaning effect.

[0007] Preferably, the pull rod is equipped with two cleaning components, which are arranged in parallel. This further improves the cleaning effect.

[0008] Preferably, the retaining ring is fixed to one end of the pull rod.

[0009] Preferably, two sliders are fixed to the outer ring surface of the fixed ring. The two sliders are symmetrical about the center of the fixed ring. One slider has a through hole through which the pull rod passes. The other slider has a threaded hole with a threaded rod threaded into it. The threaded rod is parallel to the pull rod and is connected to one end of the pull rod via a connecting plate. The connecting plate has a handle. One end of the threaded rod passes through the connecting plate and is connected to a reversible motor. The motor drives the threaded rod to rotate in both directions. The threaded rod is rotatably connected to the connecting plate via a rolling bearing.

[0010] Specifically, motor one is connected to the threaded rod via a reducer. The housing of motor one is fixed on the connecting plate. The output end of motor one is connected to the input end of the reducer, and the output end of the reducer is connected to the threaded rod. When motor one starts, it drives the threaded rod to rotate forward and backward. The fixed ring moves back and forth along the threaded rod to clean the insulator string. Cleaning can be achieved without manually pulling the rod, saving time and effort and improving cleaning efficiency.

[0011] Preferably, the inner ring surface of the fixed ring is provided with an annular groove, and a rotating ring is rotatably connected to the annular groove through a rolling bearing. A plurality of connecting blocks are evenly fixed on the inner ring surface of the rotating ring. The hinged ends of the connecting blocks and the cleaning brush extend out from the annular groove. A rack is fixed on the outer ring surface of the rotating ring. A motor is provided on the outer ring surface of the fixed ring. The motor is connected to a gear. A transmission hole communicating with the annular groove is provided on the outer ring surface of the fixed ring. The lower part of the gear extends into the transmission hole and meshes with the rack.

[0012] Specifically, motor two is a geared motor. The outer casing of motor two is fixed on a fixed ring. The output end of motor two is connected to a gear. When motor two starts, it drives the gear to rotate. The gear drives the rotating ring to rotate through a rack. The rotating ring drives the connected sweeping brush to rotate, further improving the sweeping effect.

[0013] Preferably, the rotating ring has an annular support edge on its sidewall, and the annular groove corresponding to the support edge has a matching support groove on its sidewall, allowing the support edge to rotate within the support groove. The cooperation between the support edge and the support groove improves the stability of the rotating ring.

[0014] Preferably, the cleaning brush is fan-shaped. The fan-shaped cleaning brush is designed to better match the shape of the insulator string, which is beneficial for cleaning.

[0015] This invention also includes other components that enable the rapid cleaning device for cleaning contaminants on the surface of transformer insulator strings to function properly, such as the control components for the first motor and the geared motor. These are all conventional techniques and equipment in the field. Furthermore, any devices or components not specified in this invention, such as the first motor, the geared motor, the speed reducer, the brush bristles, the rolling bearing, the hinge shaft, and the torsion spring, all employ conventional techniques and equipment in the field.

[0016] The present invention has the following advantages: it has a reasonable structural design and low cost. Each cleaning brush can rotate around the hinge axis, and the range of the brush bristles can be flexibly changed according to the different diameters of the insulator strings. This enables synchronous cleaning of the insulator strings from top to bottom and left to right, reduces cleaning dead angles, improves cleaning effect and efficiency, and reduces labor intensity. It can be applied to the daily operation and maintenance of small and medium-sized substations. Attached Figure Description

[0022] A torsion spring is provided on the hinge shaft.

[0023] The pull rod 3 may be equipped with two cleaning components, which are arranged in parallel to each other. This further improves the cleaning effect.

[0026] During operation, the fixing ring 1 is fitted onto one end of the insulator string 9, and the pull rod 3 is manually pulled to make the fixing ring 1 move back and forth along the length of the insulator string 9. During the movement, the cleaning brush 5 rotates continuously around the hinge axis as the shape (diameter) of the insulator string 9 changes, so that the fixing ring 1 can slide smoothly on the insulator string 9 while the bristles 6 of the cleaning brush 5 clean the surface of the insulator string 9.

[0027] Example 2 like Figure 4As shown, the difference between this embodiment and Embodiment 1 is that two sliders 2 are fixed on the outer ring surface of the fixed ring 1.
