[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0025] See also Figure 1 A preferred embodiment of a maintenance device for porcelain insulators is disclosed. In this embodiment, the main structure of the maintenance device for porcelain insulators is a maintenance room, which includes a maintenance room wall 1; the maintenance room wall 1 is a composite structure, and the outer side is an outer shell body formed by welding steel plates, the outer shell body is directly formed on the cement floor, and is closed on the left, right, rear and top surfaces, with only an opening reserved on the front side, the maintenance room wall 1 is formed with a sealing layer formed by cutting a stainless steel plate on the inner side of the outer shell body, and an interlayer is formed between the outer shell body and the sealing layer, and the interlayer is filled with rock wool as a thermal insulation material. The structural setting of the maintenance room wall 1 makes the maintenance room have a good thermal insulation effect, and can effectively keep the temperature in the maintenance room stable, thereby improving the maintenance effect.

[0026] An openable door 9 is installed at the front opening of the curing room. In this embodiment, the door 9 is a double-leaf structure, connected to the curing room wall 1 by hinges 10 on both sides, so that operators can enter and exit the curing room and perform necessary operations or inspections on the porcelain insulators inside. At the same time, in order to ensure the sealing and thermal insulation performance of the curing room, the structure of the door 9 is consistent with that of the curing room wall 1, which is also a sandwich structure composed of an outer shell, a sealing layer and an interlayer; at the same time, handles 8 are provided on both sides of the door 9 for convenient opening operation.

[0027] Figure 1 The embodiment shows the structure of the curing room after the left half door 9 is removed. In this embodiment, a plurality of curing racks 5 are arranged in parallel and spaced apart on the floor of the curing room. Each curing rack 5 is a hollow cabinet-type bracket, and the size of the cabinet is matched with the base cross-sectional size of the porcelain insulator 6 to ensure that the porcelain insulator 6 can be firmly placed in the cabinet. In this embodiment, the porcelain insulator 6 is placed in a horizontal position in the cabinet of the maintenance frame 5, with both ends facing outward, and each cabinet is provided with a flexible lining material on the bottom surface of the bottom plate to support the bottom surface of the horizontal porcelain insulator 6. In order to ensure the stability of the porcelain insulator 6, the maintenance frame 5 should also have a certain thickness, and its thickness is preferably 1 / 3 to 2 / 3 of the height of the porcelain insulator 6, so that while ensuring the support of the porcelain insulator 6, the connection hardware installed at both ends of the porcelain insulator 6 can be exposed from the maintenance frame 5. At the same time, the flexible lining material can also be formed with an arc convex surface that matches the umbrella section of the porcelain insulator surface to further increase the stability of the support and prevent the porcelain insulator 6 from shifting or tilting during the maintenance process. The placement of the maintenance frame 5 is convenient for spraying and maintaining the porcelain insulator 6, and also convenient for operators to check or take and place the porcelain insulator 6.

[0028] Spray plate racks are arranged on both sides of each curing frame 5. These spray plate racks have two arrangement forms, including a single-side spray plate rack 12 arranged at the outermost sides and a double-side spray plate rack 7 arranged in the middle. Both the single-side spray plate rack 12 and the double-side spray plate rack 7 are hollow bracket structures to facilitate the installation of pipelines and the arrangement of the nozzle combination of the steam nozzle 15 and the curing liquid nozzle 16. The difference between the single-side spray plate rack 12 and the double-side spray plate rack 7 is only whether the nozzle combination is assembled on one side or on both sides.

[0029] The steam nozzle 15 and the curing liquid nozzle 16 are respectively connected to the steam generating device and the curing liquid container through independent pipelines with pumping devices, so as to spray steam and curing liquid on the porcelain insulator 6. The steam nozzle 15 and the curing liquid nozzle 16 are both oriented to the facing sides to form a surface spraying structure on the single-side spraying plate frame 12 and / or the double-side spraying plate frame 7. In this embodiment, the curing liquid in the curing liquid container can be selected and prepared according to actual needs to ensure that it has a good curing effect on the porcelain insulator 6; and the curing liquid nozzle 16 adopts a wide-angle atomizing nozzle to ensure that the curing liquid can be evenly sprayed on the surface of the porcelain insulator 6 to improve the curing effect.

[0030] The curing room is provided with an air outlet frame 11 on one or both sides, and a plurality of axial flow fans 4 are evenly mounted on the surface of the air outlet frame 11 in the form of mounting brackets. These axial flow fans 4 are evenly arranged on the plate surface of the air outlet frame 11 to obtain a surface air outlet structure on the air outlet frame facing the plane where the curing frame 5 is set. Through the operation of the axial flow fans 4, the steam and atomized curing liquid sprayed from the steam nozzle 15 and the curing liquid nozzle 16 can form a circulating flow in the curing room, thereby improving the curing efficiency and uniformity.

[0031] In addition, the axial fan 4 is also provided with an auxiliary heating device 3 on the back side. The auxiliary heating device 3 uses heating elements such as electric heating tubes or steam heating tubes to provide auxiliary heating when the temperature in the curing room is insufficient, ensuring that the temperature in the curing room can be stabilized within a set range. In order to cooperate with the auxiliary heating device 3, this embodiment is also provided with a temperature and humidity recorder and a controller for monitoring the temperature and humidity in the curing room. The temperature and humidity in the curing room are monitored in real time by the temperature and humidity recorder, and the data is fed back to the controller. The controller intelligently controls the auxiliary heating device 3, the steam generating device, and the curing liquid pumping device according to the preset curing parameters to ensure that the temperature and humidity in the curing room are always maintained in the best state, and to ensure that the porcelain insulator 6 is cured under suitable temperature and humidity, thereby further improving the curing effect and stability.

[0032] At the same time, a safe operating gap is reserved between the air outlet plate frame 11 and the wall 1 of the maintenance room to facilitate operators to maintain or overhaul the equipment. In order to ensure the safety of operators, the maintenance room is isolated outside the safe operating gap with a mesh partition frame 2 with a mesh door to prevent operators from accidentally touching the relevant equipment on the air outlet plate frame 11.

[0033] In addition, the single-side spray plate rack 12, the double-side spray plate rack 7 and the lower part of the curing frame 5 in the curing room are all provided with a guide frame 13, which is arranged on a transverse guide rail 14, and the transverse guide rail 14 is preformed on the cement floor of the curing room area. The transverse guide rail 14 is perpendicular to the setting direction of the curing frame 5. At the same time, the setting direction of the curing frame 5 is also perpendicular to the closed door 9, so as to maximize the space utilization rate in the curing room. The single-side spray plate rack 12, the double-side spray plate rack 7 and the curing frame 5 can slide horizontally along the transverse guide rail 14 through the design of the guide frame 13, so that the operator can adjust the adjacent curing frames 5 and the distance between the curing frame 5 and the air outlet plate rack 11 according to the needs of the porcelain insulator 6 to meet the maintenance requirements of porcelain insulators of different specifications. The design of the curing frame 5 being arranged vertically with the door 9 allows the operator to easily enter the curing frame area at different positions when the door is opened to perform necessary operations or inspections on the porcelain insulators.

[0034] A driving device, such as an electric push rod or a manual screw, is also provided inside the curing room to drive the guide frame 13 to move, so as to realize automatic or manual operation. This movable design not only improves the convenience of operation, but also makes the curing room more adaptable and flexible, and can meet the curing needs of porcelain insulators 6 of different sizes and quantities.

[0035] In addition, in this embodiment, a micro-slope can be set on the cement floor of the maintenance room setting area. The design of the micro-slope allows the accumulated water in the maintenance room to flow naturally to the designated area. The guide groove structure at the bottom of the micro-slope can effectively guide the accumulated water out of the maintenance room, preventing the accumulated water from having an adverse effect on the maintenance equipment or porcelain insulators.

[0036] The curing device of this embodiment uses a curing room to centrally curing porcelain insulators, and sets a plurality of curing racks in the curing room, so as to achieve the purpose of curing a plurality of porcelain insulators at the same time and improve the curing efficiency. At the same time, the porcelain insulators are sprayed with steam and curing liquid by the spray plate rack, so as to ensure the comprehensiveness and uniformity of the curing effect. In addition, the working state of the auxiliary heating device and the spray plate rack is automatically adjusted by the controller, so as to achieve the precise control of the environment in the curing room and ensure the stability and reliability of the curing effect.
