Description

Technical Field

[0001] This utility model relates to the technical field of cable fireproof coating construction tools, and more specifically, it relates to cable fireproof coating spraying device. Background Technology

[0002] Cable fire-retardant coating spraying equipment is a specialized device used in the power and telecommunications industries to improve the fire resistance of cables. By uniformly applying fire-retardant coating to the cable surface, a flame-retardant protective layer is formed, slowing down the combustion rate of the cable in high-temperature environments and buying time for fire rescue and personnel evacuation. This device plays a crucial role in cable installation and maintenance of aging cables, effectively reducing the risk of cable fires and ensuring the safe and stable operation of power and communication systems.

[0003] However, existing methods for applying fire-retardant coatings to cables have significant shortcomings. Traditionally, when using a brush, the irregular, curved surface of the cable (such as the irregular shape of a multi-core cable) makes it difficult for the brush to fully adhere to the surface, resulting in uneven coating and affecting the fire-retardant effect. While professional spraying equipment can achieve more uniform coating, these devices are often large-scale production line equipment with poor portability, making them unsuitable for on-site spraying of already installed cables (such as overhead cables), thus limiting their application in later maintenance scenarios. Although portable electric spray guns are now available, in actual use, the paint from these guns can mostly only be sprayed in a designated direction. The cylindrical surface of the cable, located behind the spray direction, is usually not covered, requiring recoating, which severely impacts spraying efficiency and effect. Furthermore, cleaning traditional electric spray guns after use is quite complex. The connection between the nozzle and the paint tank is often difficult to clean, which can easily lead to blockage over time, affecting the coating effect. Therefore, there is an urgent need for a cable fire-retardant coating spraying device to solve the above problems. Utility Model Content

[0028] Please see Figures 1-4 A cable fire-retardant coating spraying device includes an electric spray gun 1, a battery 2 at the lower end of the electric spray gun 1, a connecting seat 3 at the output end of the electric spray gun 1, a first connector 4 detachably connected to one end of the connecting seat 3, a paint supply pipe 6 rotatably connected to the outer surface of the first connector 4 via a hinge block 5, a connecting cover 8 at the lower surface of the paint supply pipe 6, a paint storage tank 9 detachably connected to the lower surface of the connecting cover 8, two paint supply pipes 6 arranged symmetrically, a paint supply channel 7 opened on the inner side wall of the paint supply pipe 6, a sealing strip 10 located on the outer side of the paint supply channel 7 on the inner side wall of the paint supply pipe 6, a first external thread 11 opened on the outer surface of the paint supply pipe 6, and a fastening threaded ring 12 threadedly connected to the outer surface of the first external thread 11.

[0029] Specifically, the connecting seat 3 of the electric spray gun 1 is detachably connected to the first connecting head 4. The first connecting head 4 is rotatably connected to two symmetrical paint supply pipes 6 through the hinge block 5. The inner side of the first connecting head 4 has a paint supply channel 7, and the outer side has a first external thread 11 that is threadedly connected to the fastening threaded ring 12. The sealing strip 10 on the inner wall achieves a seal when closed. One end of the paint supply pipe 6 is connected to the second connecting head 14 through the second external thread 13. After use, the second connecting head 14 is unscrewed to separate the nozzle from the paint supply pipe 6. Then the fastening threaded ring 12 is loosened, and the two paint supply pipes 6 are rotated around the hinge block 5 to open outward. At this time, the paint supply channel 7 is fully exposed, and the sealing strip 10 is released from the sealed state as the paint supply pipe 6 opens. The inner wall of the channel can be directly rinsed with clean water or solvent to remove residual paint. This structure avoids blockage caused by paint solidification and ensures smooth paint delivery in the next use.

[0030] Please see Figures 1-7 The outer surface of the first connector 4 is rotatably connected to a paint supply pipe 6 via a hinge block 5. A second external thread 13 is formed on the outer surface of one end of the paint supply pipe 6. A second connector 14 is threaded onto the outer surface of the second external thread 13. A semi-circular nozzle 15 is fixedly connected to one end of the second connector 14. A connecting pipe 18 is fixedly connected to the outer surface of the semi-circular nozzle 15. One end of the connecting pipe 18 is fixedly connected to the outer surface of a quarter-circular nozzle 16. The interior of the semi-circular nozzle 15 communicates with the interior of the quarter-circular nozzle 16 via the connecting pipe 18. The quarter-circular nozzle 16 is hinged to one end of the semi-circular nozzle 15. Two circular nozzles 16 are provided and arranged symmetrically. A pressing plate 17 is fixedly connected to the outer surface of the circular nozzles 16. Spray holes 19 are provided on the inner sidewalls of the two circular nozzles 16 and the inner sidewalls of the semi-circular nozzles 15. Several spray holes 19 are provided and are evenly distributed in a ring array. Several bristles 22 are provided and are evenly distributed in a rectangular array. Mounting grooves 20 are provided on the inner sidewalls of the two circular nozzles 16 and the inner sidewalls of the semi-circular nozzles 15. Plastic clips 21 are movably connected to the inner sidewalls of the mounting grooves 20. Bristles 22 are fixedly connected to the outer surface of the plastic clips 21.

[0031] Specifically, the second connector 14 fixes the semi-circular nozzle 15, with two symmetrical quarter-circular nozzles 16 hinged at both ends. The outer surface is penetrated by the connecting pipe 18. The inner walls of all three are provided with annular array of paint spray holes 19 and mounting grooves 20. A plastic clip 21 with brush bristles 22 is movably connected in the mounting groove 20. A pressing plate 17 is provided on the outer surface of the quarter-circular nozzle 16. During spraying, pressing the pressing plate 17 causes the quarter-circular nozzle 16 to open around the hinge. After the cable is inserted, it is released. The elasticity of the connecting pipe 18 and the pressure of the paint cause the semi-circular nozzle 15 and the quarter-circular nozzle 16 to close and form a complete ring. The fireproof paint is sprayed out in a ring through the paint spray holes 19, covering the entire circumference of the cable. At the same time, the brush bristles 22 evenly smooth the paint, eliminating blind spots in the spraying. This structure increases the coverage area of ​​a single spray compared to traditional equipment, improves the uniformity of the coating, and eliminates the need for repeated direction adjustments, thus improving construction efficiency.

[0032] In summary, when using the entire equipment: First, pour the fire-retardant paint into the paint storage tank 9, then install the paint storage tank 9 on the connecting cover 8. Hold the electric spray gun 1 to spray. Squeeze the two pressure plates 17; at this time, the two quarter-ring nozzles 16 will rotate along the hinge with the semi-ring nozzle 15, causing the ends of the two quarter-ring nozzles 16 to open outwards. Then, insert the two plastic clips 21 from the ends of the mounting slots 20 respectively. Then, release the pressure plates 17. During spraying, press the two pressure plates 17 again to open the ends of the two quarter-ring nozzles 16 and secure them to the outside of the cable to be treated. After releasing the two pressure plates 17, the two quarter-ring nozzles 16 will automatically close due to the elasticity of the connecting pipe 18. The high pressure inside the connecting pipe 18 during operation will also cause the two quarter-ring nozzles 16 to close. Finally, press the switch on the electric spray gun 1; the electric spray gun 1 will then provide high-pressure gas during operation. This process carries the fire-retardant coating out of the paint storage tank 9 and supplies it to the semi-circular nozzle 15 through the paint supply channel 7. The coating is then supplied to the quarter-circular nozzle 16 via the connecting pipe 18, and finally sprayed out from the spray holes 19 on the inner walls of the semi-circular nozzle 15 and the quarter-circular nozzle 16. The sprayed paint is evenly spread by the brush bristles 22 as the device moves relative to the cable. The semi-circular nozzle 15 and the two quarter-circular nozzles 16 completely surround the cable, allowing for one-time coating and significantly improving spraying efficiency and effect. The entire device is more portable than large equipment. After use, the second connector 14 and the fastening threaded ring 12 can be unscrewed. At this time, the two paint supply pipes 6 can rotate outwards along the hinge block 5, exposing the paint supply channel 7. This allows for cleaning of the inside of the paint supply channel 7, preventing paint from adhering to the inner wall and causing blockage.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
