Description

Technical Field

[0001] The utility model relates to the field of spraying equipment, in particular to an anti-corrosion material spraying gun. Background Art

[0002] Offshore wind power is a key area for renewable energy development, boasting abundant resources, high power generation hours, minimal land occupation, and suitability for large-scale development. However, due to differences from onshore environments, offshore wind power equipment requires different levels of protection, necessitating the application of anti-corrosion materials to the equipment surface. While equipment with anti-corrosion materials may appear intact upon shipment, damage during transportation and installation is inevitable, compromising the overall protection of the equipment. This requires prompt detection and repair of damaged areas during equipment inspections.

[0003] However, in this repair process, such as for large pipelines, many equipment are large in size, and manual grip of the spray gun is very inconvenient and unstable, and the quality of the repair cannot be guaranteed. Utility Model Content

[0004] Therefore, the utility model provides an anti-corrosion material spray gun, which solves the problem of insufficient spraying operation stability of maintenance personnel in current offshore wind power maintenance scenarios.

[0005] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] A spray gun for anti-corrosion materials, comprising a liquid storage tank, a spray gun, and a connecting pipe connecting the liquid storage tank and the spray gun; the spray gun is connected to a support assembly for supporting the spray gun; the support assembly comprises a connecting rope hung on the spray gun and a telescopic buckle assembly for winding up the connecting rope; a hook is provided at the end of the connecting rope; the spray gun is provided with a hanging portion adapted to be connected to the hook; the telescopic buckle assembly is fixed on a rotating base; and the bottom of the rotating base is provided with a connecting piece for fixing to the periphery of the position to be sprayed.

[0007] Preferably, the connecting member is a magnetic attraction portion.

[0008] Preferably, the connecting member is a suction cup.

[0009] Preferably, there are a plurality of suction cups, and they are arranged in a dot matrix.

[0010] Preferably, there are two support assemblies.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] Based on the traditional spray gun, this technical solution adds a support component for off-site maintenance. During use, the support component provides an auxiliary supporting force from the outside, making it easier for maintenance personnel to operate. The maintenance personnel only need to provide a small supporting force to overcome the spray gun's own gravity; it is also more labor-saving during mobile spraying. During the movement, the connecting rope always has a pulling force. The maintenance personnel flexibly adjust the force to match the pulling force of the connecting rope. The combination of the two can better ensure the stability of movement during the spraying process; the overall structure of the connecting rope is installed on a rotating base, so that the connecting rope will not have a fold angle with the rope end, ensuring the stable power supply of the connecting rope and the subsequent extension and retraction are also smoother.

[0018] The following will describe the implementation methods of the present invention in detail with reference to specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Example

[0020] refer to Figure 1, a spray gun for anti-corrosion materials, comprising a liquid storage tank 1, a spray gun 2, and a connecting pipe 3 connecting the liquid storage tank 1 and the spray gun 2, a driving part is arranged on the liquid storage tank 1 to realize the spraying operation of the spray gun 2; the spray gun 2 is connected to a support assembly 4 for supporting the spray gun 2, and the support assembly 4 includes a connecting rope 41 hung on the spray gun 2, and a telescopic buckle assembly 42 for winding the connecting rope 41, wherein the telescopic buckle assembly 42 generally includes a rope drum and a coil spring (or torsion spring) inside the rope drum to realize the extension and contraction of the connecting rope 41; the telescopic buckle assembly 42 can also be replaced by a similar component structure that can be purchased on the market, which can realize the functions required by the present technical solution, and will not be elaborated here; the end of the connecting rope 41 is provided with a hook, and the spray gun 2 is provided with a hanging part 21 that is adapted to be connected to the hook, and the telescopic buckle assembly 42 is fixed on a rotating base 43, and the bottom of the rotating base 43 is provided with a connecting member 44 for fixing to the side of the position to be sprayed. Among them, since most of the equipment is made of metal, it is preferred that the connecting member 44 is a magnetic attraction portion, which has a strong magnetic structure and can be stably adsorbed on the side of the position to be sprayed;

[0021] Similarly, a suction cup can be used as the connecting member 44; the suction cup can be a single, larger one, allowing for flexible selection based on the actual application scenario, and is particularly suitable for scenarios where the circumferential surface is flat and lacks magnetic attraction. Accordingly, multiple suction cups can be provided, arranged in a dot matrix, allowing for a certain degree of construction operation capability even in situations where the surface is not flat and lacks magnetic attraction.

[0022] The present technical solution adds a support assembly 4 for off-site maintenance on the basis of the traditional spray gun 2. During use, the support assembly 4 provides an auxiliary supporting force externally, making it easier for maintenance personnel to operate. The maintenance personnel only need to provide a small supporting force to overcome the gravity of the spray gun 2 itself; it is also more labor-saving during mobile spraying. During the movement, the connecting rope 41 always has a pulling force. The maintenance personnel flexibly adjust the force to match the pulling force of the connecting rope 41. The combination of the two can better ensure the stability of movement during the spraying process; the overall structure of the connecting rope 41 is installed on a rotating base 43, so that the connecting rope 41 will not have a fold angle with the rope end, ensuring the stable power supply of the connecting rope 41 and the subsequent extension and retraction are also smoother.

[0023] During use, different types of telescopic buckle components 42 can be selected according to the actual maintenance scenario; and the connection rope 41 can be selected with a fixed length or a flexible telescopic length:

[0024] When the length is fixed, Figure 2 As shown, it is suitable for arc or curve damage, and the fixed point is set at the center of the arc to ensure that the connecting rope 41 is in a straight stretched state;

[0025] In flexible scaling state, such as Figure 3 As shown, this is suitable for linear damage. Once the fixed point is selected, the maintenance worker moves the spray gun 2 due to body rotation or foot movement, causing changes in applied force. During this movement, the connecting rope 41 automatically stretches and retracts to achieve different supporting forces, thereby achieving a flexible offset and balancing effect for this force change. The above two structures are highly practical and reduce the labor intensity of maintenance personnel.

[0026] Similarly, when necessary, additional support points can be added, for example, by using two support components 4; Figure 4 As shown, under this structure, two supporting components 4 simultaneously apply supporting force to form two auxiliary supporting points, which can be more flexible for repairing complex damage scenarios.

[0027] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
