Description

Technical Field

[0001] This utility model relates to the field of air-raid shelter wall spraying technology, and more specifically, to an air-raid shelter wall anti-mildew and moisture-proof spraying device. Background Technology

[0002] Anti-mold and moisture-proof spray is a highly effective protective technology specifically designed to address mold growth and moisture damage caused by humid environments. This product uses environmentally friendly polymer materials and antibacterial ingredients to form a dense, breathable protective film on the surface of objects, effectively blocking moisture penetration and inhibiting mold spore growth. It has a wide range of applications, suitable for damp areas such as bathrooms, kitchens, and basements, as well as furniture, walls, clothing, books, and other items susceptible to moisture. Application is simple; it can be quickly applied by direct spraying without requiring professional equipment. After drying, it is colorless and leaves no residue. Anti-mold and moisture-proof spray not only provides immediate moisture protection but also offers long-lasting anti-mold protection.

[0003] The interior of air-raid shelters is dark, damp, and poorly ventilated. To prevent mold growth on the walls, it is necessary to spray paint with moisture-proof and antibacterial ingredients. Currently, manual brushing and ordinary spraying equipment are mainly used. The inner walls and ceilings of air-raid shelters are usually arched, and the nozzle angle of ordinary spraying equipment is fixed, resulting in poor adaptability to the shape of the air-raid shelter. Both manual brushing and current equipment spraying suffer from low efficiency. In view of this, we propose an anti-mold and moisture-proof spraying device for air-raid shelter walls. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spraying device for mildew and moisture prevention on the walls of air-raid shelters, so as to solve the technical problem of low efficiency in both manual brushing and equipment spraying.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mildew-proof and moisture-proof spraying device for air-raid shelter walls, comprising a spraying trolley and a spraying mechanism mounted on the spraying trolley. The spraying trolley includes a movable base and a paint tank mounted on the movable base. The spraying mechanism includes a mounting plate fixedly mounted on the paint tank. A rotating plate is rotatably mounted on the front of the upper part of the mounting plate. An upper spray nozzle is provided at the top of the rotating plate. Symmetrically distributed swing rods are rotatably connected to the bottom end of the rotating plate. Mounting components are symmetrically mounted on the front of the mounting plate below the rotating plate. The ends of the swing rods are rotatably connected to the mounting components. An adjusting rod is provided on the mounting components. A side spray nozzle is provided at the end of the adjusting rod. The adjusting rod includes a sleeve rod and a telescopic rod telescopically mounted inside the sleeve rod. A limiting hole is provided on the telescopic rod. A guide rod for limiting and guiding the mounting components is mounted on the mounting plate.

[0006] Preferably, the movable base is provided with a push rod, and the bottom surface of the movable base is provided with a series of moving wheels.

[0007] Preferably, a motor is provided on the back of the mounting plate, and the output shaft of the motor is connected to the axis of rotation of the rotating plate.

[0008] Preferably, the swing arm is arc-shaped along its long axis, the mounting member is L-shaped along its long axis, and the width of the mounting member gradually increases from front to back.

[0009] Preferably, the top surface of the paint tank is provided with a feed pipe, the paint tank is provided with a spray pump, the spray pump is provided with a supply pipe, and the end of the supply pipe is provided with three pipes, which are respectively connected to the upper spray head and the side spray head.

[0010] Preferably, the guide rod includes a mounting part, the end of the mounting part is bent forward at 90 degrees to form a bending part, the end of the bending part is bent downward to form a guide part, the guide part is bent in a C-shape, and the guide part is located inside the limiting hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model designs a reciprocating rotating plate structure. Driven by a motor, the rotating plate rotates left and right, thereby driving the top spray head to move along an arc-shaped trajectory, perfectly matching the structural characteristics of the arched top surface of the air-raid shelter. At the same time, through the linkage design of the swing rod and the mounting parts, the side spray head can swing up and down. With the help of the telescopic adjustment rod, it realizes all-round adaptive spraying of the complex curved wall surface of the air-raid shelter. The staff only needs to push the spraying trolley to move along the air-raid shelter to complete the spraying work, solving the problem of low efficiency in both manual brushing and equipment spraying.

[0013] 2. This utility model also features a guide rod structure and a unique guide rod and limiting hole mechanism that allow the side spray head to automatically adjust its distance from the wall during up-and-down swinging. When the side spray head swings to its highest and lowest points, it automatically approaches the wall under the action of the C-shaped guide, ensuring that the paint spraying distance is always optimal. This effectively avoids paint splashing or uneven coverage caused by improper distance, further enhancing the adaptability and spraying effect of the spraying. It effectively overcomes the technical defects of traditional manual painting or fixed spray head equipment, such as low efficiency and poor adaptability. Attached Figure Description

Detailed Implementation

[0020] like Figures 1 to 5 As shown, this utility model relates to a mildew-proof and moisture-proof spraying device for air-raid shelter walls, including a spraying trolley 100 and a spraying mechanism 200 mounted on the spraying trolley 100. The spraying trolley 100 includes a movable base 101 and a paint tank 103 mounted on the movable base 101. The spraying mechanism 200 includes a mounting plate 201 fixedly mounted on the paint tank 103. A rotating plate 202 is rotatably mounted on the front of the upper part of the mounting plate 201. An upper spray nozzle 204 is provided at the top of the rotating plate 202, and the bottom end of the rotating plate 202 is rotatable. A symmetrically distributed swing rod 205 is connected to the mounting plate 201, which is located below the rotating plate 202. A mounting component 206 is symmetrically and rotatably mounted on the front of the mounting plate 201. The end of the swing rod 205 is rotatably connected to the mounting component 206. An adjusting rod 207 is provided on the mounting component 206. A side nozzle 208 is provided at the end of the adjusting rod 207. The adjusting rod 207 includes a sleeve rod and a telescopic rod that is telescopically set inside the sleeve rod. A limit hole 2071 is opened on the telescopic rod. A guide rod 209 is installed on the mounting plate 201 to limit and guide the mounting component 206. This invention uses a reciprocating rotating plate 202 to drive the upper spray head 204 to move along an arc-shaped trajectory, perfectly matching the arched top structure of the air-raid shelter. At the same time, the swing rod 205 and the mounting part 206 are linked to make the side spray head 208 swing up and down. With the help of the telescopic adjustment rod 207 and the guide rod 209, the side spray head 208 automatically adjusts its distance from the wall during the swing, ensuring uniform and efficient spraying. This effectively solves the problems of low efficiency and poor adaptability of manual painting or fixed spray head equipment.

[0021] Specifically, a push rod 102 is provided on the movable base 101, and a series of casters are arranged on the bottom surface of the movable base 101. The push rod 102 and casters facilitate the operator to move the device inside the air-raid shelter, completing the spraying work during the movement.

[0022] Furthermore, a motor 203 is provided on the back of the mounting plate 201, and the output shaft of the motor 203 is connected to the rotation axis of the rotating plate 202. The operation of the motor 203 can drive the rotating plate 202 to rotate back and forth. When the rotating plate 202 rotates back and forth, the upper spray head 204 can make an arc-shaped movement, thereby adapting to the arc shape of the top of the air-raid shelter and facilitating spraying work on it.

[0023] It is worth noting that the swing rod 205 is arc-shaped along its long axis, and the mounting part 206 is L-shaped along its long axis, with the width of the mounting part 206 gradually increasing from front to back. The gradual increase in width of the mounting part 206 from front to back ensures the strength of the mounting part 206. By rotating the rotating plate 202 back and forth, the swing rod 205 can swing up and down, thereby causing the side spray nozzle 208 to swing up and down to perform top-to-bottom spraying work on the side of the inner wall of the air-raid shelter.

[0024] It is worth mentioning that the top surface of the paint tank 103 is equipped with a feed pipe, and a spray pump is installed inside the paint tank 103. The spray pump is equipped with a supply pipe, and the end of the supply pipe has three branches, which are respectively connected to the upper spray head 204 and the side spray head 208. By operating the spray pump, the paint in the paint tank 103 can be transported to the upper spray head 204 and the side spray head 208, and the paint can be sprayed out from the spray head for spraying work.

[0025] It is worth noting that the guide rod 209 includes a mounting part 2091, the end of the mounting part 2091 is bent forward at a 90-degree angle to form a bending part 2092, the end of the bending part 2092 is bent downward to form a guide part 2093, the guide part 2093 is bent in a C-shape and is located inside the limiting hole 2071. The bending part 2092 is used to change the position of the guide part 2093, so that the guide part 2093 can limit and guide the side nozzle 208. During the spraying process on the side of the inner wall of the air-raid shelter, the side nozzle 208 will swing up and down. The guide part 2093 of the guide rod 209 can limit and guide the side nozzle 208. Since the guide part 2093 is C-shaped, when the side nozzle 208 swings from the middle to the upper and lower direction, it can move towards the inner wall of the air-raid shelter under the action of the guide part 2093. During this process, the adjusting rod 207 will extend and retract, thereby changing the distance between the side nozzle 208 and the inner wall of the air-raid shelter, which can improve the spraying effect of the side nozzle 208 on the inner wall of the air-raid shelter.

[0026] Working Principle: This embodiment provides a mildew-proof and moisture-proof spraying device for air-raid shelter walls. In use, the operator pushes the spraying trolley 100 along the interior of the air-raid shelter using the push rod 102. The motor 203 starts, causing the rotating plate 202 to rotate reciprocally left and right. The upper spray nozzle 204 on the top of the rotating plate 202 then moves in an arc shape to adapt to the curved surface of the arched structure at the top of the air-raid shelter, achieving uniform spraying of the top surface. Simultaneously, the reciprocating rotation of the rotating plate 202, through the swing rod 205 connected to its bottom, causes the mounting component 206 to swing up and down around the rotation point on the mounting plate 201. The adjusting rod 207 on the mounting component 206 then extends and retracts accordingly. The side spray nozzle 208 at the end of the adjusting rod 207 moves along the guide rod 201. Under the limiting and guiding effect of the guide part 2093 of 09, it can not only swing up and down, but also move closer or further away from the side wall of the air-raid shelter along the C-shaped guide part 2093 during the swing, thereby automatically adjusting the distance between the side nozzle 208 and the side wall, ensuring that the side nozzle 208 always covers the side wall with the best distance during the up and down swing. The spraying pump in the paint tank 103 delivers the anti-mildew and moisture-proof paint to the upper nozzle 204 and the two side nozzles 208 through the supply pipe, realizing synchronous, efficient and uniform spraying of the top and sides, effectively improving spraying efficiency and coverage quality, adapting to the complex internal structure of the air-raid shelter, and overcoming the problems of low efficiency and poor adaptability of traditional manual or fixed nozzle equipment.
