Description

Technical Field

[0001] This invention relates to the field of electric spraying technology, specifically to an RTV coating spraying device. Background Technology

[0002] Insulators are commonly used in high-voltage overhead transmission lines for insulation and conductor fixing. Environmental contaminants often accumulate on the insulating surface of insulators. Under humid conditions, soluble substances in the contaminants gradually dissolve in water, forming a conductive film on the insulating surface. This significantly reduces the insulator's insulating capacity, leading to strong discharge phenomena under the influence of an electric field. To prevent this discharge, an RTV (Reactive Voltage Transmission) anti-flashover coating is typically applied to the surface of the insulator. This RTV coating effectively solves the flashover problem.

[0003] In the actual insulator production process, the application of RTV anti-flashover coating mainly adopts two methods: spraying and dipping. Among them, the spraying method has the following problems:

[0004] (1) When using a general spraying device, the uniformity of the spraying is poor, which affects the quality of the spraying.

[0005] (2) Existing manual spraying devices can only spray at a single point. The spraying position is adjusted by manual hand movement, making it difficult to spray and cover some special positions. It is impossible to spray multiple points on the insulator at the same time, which affects the spraying efficiency. Summary of the Invention

[0006] To address the technical problems existing in the background art, the present invention provides an RTV coating spraying device, which has two spraying methods and can realize more convenient and faster RTV coating spraying.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0008] RTV paint spraying equipment includes:

[0009] Straight rod assembly;

[0010] The deformable component is installed at the front end of the straight rod component. The deformable component can be bent into a ring shape or unfolded into a straight strip shape. The inner ring of the ring-shaped deformable component has a nozzle.

[0011] Furthermore, the deformable assembly is composed of several rotatable joints;

[0012] A flexible hose, a first control rope, and a second control rope are inserted inside the elbow joint, with the first control rope and the second control rope located on both sides of the elbow joint, respectively.

[0013] The elbow sidewall of the second control rope is provided with a first side nozzle that communicates with the hose.

[0014] Furthermore, the toggle is provided with a first synchronous plate, a second synchronous plate, and a rotatable central shaft that can slide along the length of the toggle. The first and second synchronous plates of adjacent toggles are rotatably connected. The first and second synchronous plates are centrally symmetrically arranged on both sides of the central shaft. The first and second synchronous plates mesh with the central shaft for transmission. The central shaft can control the opening and closing of the first side nozzle.

[0015] Furthermore, the front end of the deformable component is equipped with a front end assembly, which is rotatably connected to the adjacent toggle joint. The front ends of the first control rope and the second control rope are fixedly connected to the front end assembly. The top of the front end assembly is provided with an openable and closable top nozzle, and the side wall of the front end assembly is provided with a second side nozzle that faces the same direction as the first side nozzle. The top nozzle and the second side nozzle are connected to the hose.

[0016] Furthermore, a liquid dispensing ball is rotatably arranged inside the front-end component, including a ball body, with rotating shafts at both ends of the ball body, a through internal liquid dispensing hole in the ball body, a first liquid dispensing hole in the side wall of the ball body, and a second liquid dispensing hole communicating with the first liquid dispensing hole at the end of the rotating shaft.

[0017] A second synchronization plate is slidably disposed within the front-end assembly. The second synchronization plate is rotatably connected to the first synchronization plate of the adjacent elbow joint. The second synchronization plate meshes with the rotating shaft for transmission. The rotating shaft can control the opening and closing of the second side nozzle.

[0018] Furthermore, the straight rod assembly is rotatably connected to the adjacent elbow joint, and the front end of the straight rod assembly is provided with a connecting block that can slide in a direction perpendicular to the length of the straight rod assembly. The connecting block is rotatably connected to the second synchronous plate of the adjacent elbow joint.

[0019] Furthermore, a control component is mounted on the straight rod assembly, the control component including:

[0020] The housing is fixedly connected to the straight rod assembly;

[0021] The first hinge shaft, driven by a motor, is housed inside the housing, and the rear end of the first control rope is wound around the first hinge shaft.

[0022] The second shaft, driven by a motor, is housed inside the housing, and the rear end of the second control rope is wound around the second shaft.

[0023] The pump is housed within the casing, and the rear end of the hose is connected to the pump.

[0024] Furthermore, the elbow joint has a first end face and a second end face symmetrically arranged at both ends. The first end faces at both ends of the elbow joint are parallel to each other, and the second end faces at both ends of the elbow joint form a certain angle. The rotating part is arranged at the junction of the first end face and the second end face, and adjacent elbow joints are rotatably connected through the rotating part.

[0025] Furthermore, the elbow joint has two first rope-passing holes for passing through the first control rope and two second rope-passing holes for passing through the second control rope, and the elbow joint also has a pipe-passing hole for passing through the flexible hose.

[0026] The first side nozzle is located on the elbow sidewall near the second rope hole, and the hose and the first side nozzle are connected by a side spray hole.

[0027] Furthermore, a groove is provided on the side of the elbow joint near the second rope hole, and the first and second synchronization plates are slidably disposed in the groove, while the central rotating shaft is rotatably disposed in the groove.

[0028] The beneficial effects of this invention are:

[0029] (1) When it is in a straight state, it can perform single-point spraying on the insulator, just like the existing manual spraying device, and adjust the spraying position by manually moving it to achieve full spraying coverage of the insulator.

[0030] (2) When it is in a bent state, it can be wrapped around the outer periphery of the insulator in a ring shape, so as to spray the insulator in a ring shape, making the spraying more comprehensive, uniform and efficient.

[0048] The present invention will be further described in detail below with reference to the accompanying drawings.

[0049] The RTV coating spraying device includes: a front-end assembly 11, a deformation assembly 1, a straight rod assembly 2, and a control assembly 3 connected in sequence.

[0050] The deformable component 1 is installed at the front end of the straight rod component 2. The deformable component 1 is formed by several elbows 7 rotatably connected. The deformable component 1 can be bent into a ring shape or unfolded into a straight strip shape. The inner ring of the ring-shaped deformable component 1 is provided with a nozzle, which can spray the insulator in a ring shape.

[0051] A flexible hose 4, a first control rope 5, and a second control rope 6 are threaded through the elbow joint 7, with the first control rope 5 and the second control rope 6 located on opposite sides of the elbow joint 7. Pulling the control rope on one side causes the deformable component 1 to bend to the corresponding side. A first side nozzle 707 communicating with the flexible hose 4 is provided on the side wall of the elbow joint 7 on the side of the second control rope 6. RTV coating in the flexible hose 4 can be sprayed out from the first side nozzle 707.

[0052] The specific structure of the toggle joint 7 is as follows: A first end face 701 and a second end face 702 are symmetrically arranged at both ends of the toggle joint 7. The first end faces 701 at both ends of the toggle joint 7 are parallel to each other, and the second end faces 702 at both ends of the toggle joint 7 form a certain angle. In actual implementation, there are a total of 14 toggle joints 7 plus the front end component 11, and the angle between the second end faces 702 is 22.5 degrees. A rotating part 705 is disposed at the junction of the first end face 701 and the second end face 702, and adjacent toggle joints 7 are rotatably connected through the rotating part 705. When the first end faces 701 of adjacent toggle joints 7 are in contact, the deformation component 1 is in a straight state. When the second end faces 702 of adjacent toggle joints 7 are in contact, the deformation component 1 is in a bent state.

[0053] The elbow joint 7 has two first rope-passing holes 703 for passing through the first control rope 5 and two second rope-passing holes 704 for passing through the second control rope 6. The two first rope-passing holes 703 and two second rope-passing holes 704 are located at the four corners of the elbow joint 7. The elbow joint 7 also has a pipe-passing hole 708 for passing through the flexible hose 4. The first side nozzle 707 is located on the side wall of the elbow joint 7 near the second rope-passing hole 704. The flexible hose 4 and the first side nozzle 707 are connected by a side spray hole 709. The central rotating shaft 9 is rotatably mounted at the connection between the side spray hole 709 and the first side nozzle 707.

[0054] A groove 706 is provided on the side of the elbow joint 7 near the second rope hole 704. The first synchronization plate 8 and the second synchronization plate 10 are slidably disposed in the groove 706, and the central rotating shaft 9 is rotatably disposed in the groove 706. The first synchronization plate 8 and the second synchronization plate 10 can slide along the length of the elbow joint 7. The first synchronization plate 8 and the second synchronization plate 10 are centrally symmetrically disposed on both sides of the central rotating shaft 9. The first synchronization plate 8 and the second synchronization plate 10 of adjacent elbow joints 7 are rotatably connected. The first synchronization plate 8 and the second synchronization plate 10 mesh with the central rotating shaft 9 for transmission. The central rotating shaft 9 can control the opening and closing of the first side nozzle 707. That is, the central rotating shaft 9 has a flow channel. When the flow channel of the central rotating shaft 9 is connected to the side spray hole 709, the first side nozzle 707 is opened, and RTV paint can be sprayed. When the flow channel of the central rotating shaft 9 is misaligned with the side spray hole 709, the first side nozzle 707 is closed.

[0055] The front end assembly 11 is rotatably connected to the adjacent elbow 7, and the front ends of the first control rope 5 and the second control rope 6 are fixedly connected to the front end assembly 11. The top end of the front end assembly 11 is provided with an openable and closable top nozzle 1101, and the side wall of the front end assembly 11 is provided with a second side nozzle 1102 in the same direction as the first side nozzle 707. The top nozzle 1101 and the second side nozzle 1102 are connected to the hose 4.

[0056] To ensure that the second nozzle 1102 of the front end assembly 11 opens when the deformable component 1 bends, and the top nozzle 1101 of the front end assembly 11 opens when the deformable component 1 straightens. A liquid-distributing ball 12 is rotatably disposed inside the front end assembly 11. The liquid-distributing ball 12 specifically includes a ball 1204, with rotating shafts 1205 at both ends of the ball 1204, a through-hole 1201 in the ball 1204, a first liquid-distributing hole 1202 on the side wall of the ball 1204, and a second liquid-distributing hole 1203 communicating with the first liquid-distributing hole 1202 at the end of the rotating shaft 1205.

[0057] A second synchronization plate 10 is slidably disposed within the front-end assembly 11. The rear end of the second synchronization plate 10 is rotatably connected to the first synchronization plate 8 of the adjacent elbow 7. The front end of the second synchronization plate 10 is engaged with the rotating shaft 1205 for transmission. The rotating shaft 1205 can control the rotation of the dispensing ball 12, thereby controlling the opening and closing of the second side nozzle 1102.

[0058] Specifically: when the dispensing ball 12 rotates to the liquid outlet 1201 and connects the top nozzle 1101 to the hose 4, the RTV coating can be sprayed out from the top nozzle 1101. When the dispensing ball 12 rotates to the first liquid outlet 1202 and connects to the hose 4, the RTV coating can be sprayed out from the second side nozzle 1102. That is, when the deformable component 1 bends, the second side nozzle 1102 of the front end component 11 opens; when the deformable component 1 straightens, the top nozzle 1101 of the front end component 11 opens.

[0059] The straight rod assembly 2 is rotatably connected to the adjacent elbow joint 7. The front end of the straight rod assembly 2 is provided with a connecting block 201 that can slide horizontally in a direction perpendicular to the length of the straight rod assembly 2. The connecting block 201 is rotatably connected to the second synchronization plate 10 of the adjacent elbow joint 7. Through the connecting block 201 and the sequentially connected first synchronization plate 8, central rotating shaft 9, and second synchronization plate 10, the elbow joints 7 can rotate at different angles, meaning that the rotation angle between each elbow joint 7 is equal, thereby allowing the deformable assembly 1 to form a perfect circular arc.

[0060] The control component 3 includes a housing 301 fixedly connected to the straight rod assembly 2. Inside the housing 301 are a first hinge 302 and a second hinge 303 driven by a motor. The rear end of the first control rope 5 is wound around the first hinge 302, and the rear end of the second control rope 6 is wound around the second hinge 303. A pump 304 is also installed inside the housing 301. The rear end of the hose 4 is connected to the pump 304, which can deliver RTV coating into the hose 4.

[0061] When it is in the straight position, RTV paint is sprayed from the top nozzle 1101 to spray the insulator at a single point, and the spraying position can be adjusted by hand to achieve full coverage of the insulator.

[0062] When annular spraying is required on the insulator, the second pivot 303 rotates to tighten the second control rope 6, while the first pivot 302 rotates to loosen the first control rope 5, causing the second end faces 702 of adjacent elbows 7 to contact. This device can then encircle the insulator in a ring shape, allowing RTV coating to be applied from the first side nozzle 707 and the second side nozzle 1102, resulting in a more comprehensive, uniform, and efficient coating. After the annular spraying is complete, the second pivot 303 rotates to loosen the second control rope 6, while the first pivot 302 rotates to tighten the first control rope 5, causing the first end faces 701 of adjacent elbows 7 to contact, and the deformable assembly 1 returns to its straightened state.

[0063] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
