Description

Technical Field

[0001] This utility model relates to the field of RH immersion pipe maintenance, specifically to a spray gun head for RH immersion pipe maintenance. Background Technology

[0002] Commonly used spray gun types in RH impregnation pipe maintenance include, but are not limited to, all-angle manual spray guns. These spray guns are designed with a base and a spray gun body, and the entire angle of the spray gun is adjustable via a support plate and positioning rod on the base, thus facilitating manual repair of the inner wall of the impregnated pipe.

[0003] By positioning the spray gun nozzle below the immersion tube, water and solution are added to the spray gun storage tank through the water pipe and material pipe. The water and solution mix in the spray gun storage tank to form the spray gun material. Then, the position of the positioning rod on the support plate is adjusted to change the working height of the spray gun. After the spray gun is turned on, the spray gun will evenly spray the spray gun material onto the area that needs to be repaired on the inner wall of the immersion tube.

[0004] In existing technology, water and solution are added to the spray gun storage tank through water pipes and material pipes. The water and solution in the spray gun storage tank will then mix and be used. However, allowing the water and solution in the spray gun storage tank to mix on their own is problematic. First, the mixing time is too slow and inconvenient to use. Second, the water and solution will mix unevenly, resulting in uneven spraying of the repair material and failure to complete the repair work. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5 As shown, this utility model is a spray gun head for RH impregnation pipe maintenance, including a base 1; a rotating shaft 13 is rotatably connected to the top of the base 1; a working barrel 2 is fixedly connected to the top of the rotating shaft 13; a lifting assembly is provided inside the working barrel 2; the lifting assembly includes a support block 14; a mixing tank 8 is fixedly connected to one end of the support block 14; an agitator 21 is rotatably connected inside the mixing tank 8; a fan blade 22 is fixedly connected to the agitator 21; a drive motor 12 is fixedly connected to the bottom of the mixing tank 8; the drive motor 12 is connected to the agitator 21; a water inlet pipe 9 is fixedly connected to one side of the mixing tank 8; and a material pipe 10 is fixedly connected to the other side of the mixing tank 8.

[0026] The internal motor installed in the base 1 drives the rotating shaft 13 to rotate, which in turn drives the working barrel 2 to a designated position. Then, water and liquid are added into the mixing tank 8 through the water inlet pipe 9 and the material pipe 10. The drive motor 12 at the bottom of the mixing tank 8 drives the stirring shaft 21 inside the mixing tank 8 to rotate. The rotating stirring shaft 21 drives the fan blade 22 to rotate, which stirs the water and liquid entering the mixing tank 8, ensuring that the water and liquid in the mixing tank 8 are fully mixed and avoiding uneven mixing. Then, the lifting component drives the mixing tank 8 to rise or fall, allowing the device to spray.

[0027] Please refer to the attached image. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, specifically, a limiting post 19 is fixedly connected inside the mixing tank 8; four limiting posts 19 are provided and are respectively arranged at the four corners inside the mixing tank 8; a float 17 is slidably connected to the limiting post 19; a spring 18 is fixedly connected inside the float 17; multiple springs 18 are provided and are equidistantly arranged inside the float 17; a blocking block 16 is fixedly connected to the end of the spring 18 away from the float 17; during operation, when water and liquid enter the mixing tank 8, the float 17 will float under the action of buoyancy, and the floating float 17 will cause the blocking block 16 to move, allowing the blocking block 16 to slowly rebound under the spring 18. The liquid slides into the inlet pipe 9 and the feed pipe 10, blocking them. This is designed so that water and liquid will continuously flow into the mixing tank 8. When the water and liquid overflow the inlet pipe 9 and the feed pipe 10, the mixture will flow back into the inlet pipe 9 and the feed pipe 10, causing contamination at the output end. This will result in contamination of the solution discharged from the feed pipe 10 and the inlet pipe 9. When the liquid level in the mixing tank 8 drops, the float 17 will drop accordingly. The blocking block 16 is designed with a conical slope. When the float 17 drops, the blocking block 16 will slide out of the inlet pipe 9 and the feed pipe 10, and the inner wall of the mixing tank 8 will press the blocking block 16 and the spring 18 to move into the float 17.

[0028] Please refer to the attached image. Figure 1 and Figure 4 As shown, specifically, a lifting screw 6 is rotatably connected inside the working barrel 2; a lifting motor 24 is fixedly connected to the bottom of the working barrel 2; the lifting motor 24 is connected to the lifting screw 6; a lifting block 15 is rotatably connected to the lifting screw 6; one end of the lifting block 15 is fixedly connected to a support block 14; during operation, the lifting screw 6 is driven by the lifting motor 24 to rotate, and the rotating lifting screw 6 causes the lifting block 15 and the support block 14 to rise or fall, thereby driving the device to perform spraying operations at designated locations.

[0029] Please refer to the attached image. Figure 2 , Figure 3 and Figure 4 As shown, specifically, a connecting plate 23 is fixedly connected inside the mixing tank 8; the other end of the stirring shaft 21 is rotatably connected to the connecting plate 23; a water pump 20 is fixedly connected to the top of the connecting plate 23; a support pipe 5 is fixedly connected to the top of the water pump 20, and the support pipe 5 passes through the mixing tank 8; a nozzle 4 is fixedly connected to the top of the support pipe 5; during operation, the water pump 20 on the connecting plate 23 extracts the mixed liquid in the mixing tank 8, and the extracted mixed liquid is transported by the water pump 20 to the support pipe 5, and then sent to the nozzle 4 by the support pipe 5. The nozzle 4 then sprays the mixed solution out, and the rotating shaft 13 drives the working tank 2 to rotate, thereby achieving the effect of rotational spraying.

[0030] Please refer to the attached image. Figure 1 and Figure 4 As shown, specifically, a limiting groove 7 is fixedly connected inside the working barrel 2; there are two limiting grooves 7, which are symmetrically arranged inside the working barrel 2; the lifting block 15 is slidably disposed inside the limiting groove 7; during operation, when the lifting screw 6 drives the lifting block 15 to rise and fall, in order to prevent the lifting block 15 from deflecting, which would cause the mixing box 8 and the nozzle 4 to be unable to rise and fall according to the specified position, the lifting block 15 is allowed to slide inside the limiting groove 7, so that the lifting block 15 can only move up and down in the direction set by the limiting groove 7.

[0031] Please refer to the attached image. Figure 1 , Figure 2 and Figure 5 As shown, specifically, there are three water inlet pipes 9, which are equidistantly arranged on the mixing tank 8; there are three material pipes 10, which are equidistantly arranged on the mixing tank 8. During operation, the three water inlet pipes 9 and the three material pipes 10 are provided to allow water and liquid to be quickly replenished to the mixing tank 8 to meet the working requirements. They are also provided to allow the water and liquid sprayed from the water inlet pipes 9 and the material pipes 10 to have a certain impact force, thereby disturbing the water entering the mixing tank 8 for direct mixing.

[0032] Please refer to the attached image. Figure 2 , Figure 4 and Figure 5 As shown, specifically, a support column 11 is fixedly connected to the top of the working barrel 2; four support columns 11 are provided and are respectively arranged on the top of the working barrel 2; a protective top 3 is fixedly connected to the top of the support column 11; during operation, the support column 11 and the protective top 3 are provided on the top of the working barrel 2 to prevent high-temperature residue from falling down and damaging the components inside the working barrel 2 when the nozzle 4 is spraying, so the protective top 3 is used to protect the residue from falling into the working barrel 2.

[0033] The working principle of this utility model is as follows: The internal motor installed in the base 1 drives the rotating shaft 13 to rotate, which in turn drives the working barrel 2 to rotate to the designated position. Then, water and liquid are added into the mixing tank 8 through the water inlet pipe 9 and the material pipe 10. The drive motor 12 at the bottom of the mixing tank 8 drives the stirring shaft 21 inside the mixing tank 8 to rotate. The rotating stirring shaft 21 drives the fan blade 22 to rotate, which stirs the water and liquid entering the mixing tank 8, so that the water and liquid in the mixing tank 8 can be fully mixed and avoid uneven mixing. Then, the lifting component drives the mixing tank 8 to rise or fall, so that the device can spray.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
