Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering, and in particular relates to an omnidirectional sprinkler head suitable for retention spraying in manholes. Background Art

[0002] Inspection manholes in municipal pipe networks play an important role in the processes of pipe network connection, pipe network inspection, pipe network maintenance, pipe network cleaning, and pipe network repair. The service life of the inspection manholes determines the life of the pipe network to a certain extent. The overall quality of the manhole is generally affected by factors such as construction technology, construction quality, road construction, and vehicle traffic. In the middle and late stages of the service life, manholes will have various problems that affect their normal operation, mainly including: holes in the manhole wall due to movement or collapse of the surrounding soil, overall sinking of the manhole due to movement or collapse of the bottom soil, leakage in the manhole chamber, and damage to the manhole chamber structure itself.

[0003] Chinese invention CN108005121B discloses a trenchless manhole all-round repair method. This method tilts the axis of the nozzle downward relative to the horizontal direction. During the up and down movement, not only can the well wall be sprayed in all directions, but the well bottom can also be sprayed and repaired when approaching one end of the well bottom, thereby minimizing the repair dead angle inside the well chamber. Therefore, all-round spraying is crucial for repairing the inner wall of the well chamber in the manhole. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned technical problems and provide an omnidirectional nozzle suitable for manhole retention spraying, which can rotate 360 ​​degrees in all directions to spray and repair the inner wall of the well chamber in the manhole, effectively improving the service life of the manhole and the corresponding pipeline network.

[0005] In view of this, the utility model provides an omnidirectional sprinkler suitable for manhole retention spraying, which is characterized in that it includes: a sleeve, the upper and lower ends of the sleeve are respectively connected with an upper cover and a lower cover by bolts, a water inlet pipe is movably connected inside the sleeve, the upper end of the water inlet pipe is connected with a water outlet pipe, the bottom end of the water inlet pipe is threadedly connected to a spray barrel and is connected to the spray barrel, the outer wall of the spray barrel is provided with a plurality of spray holes, a self-rotating component is provided inside the water inlet pipe, the upper and lower outer walls of the water inlet pipe are both provided with bearings, and the outer wall of the bearing is movably connected to the inner wall of the sleeve.

[0006] In this technical solution, the water inlet pipe is movably connected to the sleeve through bearings at both ends to ensure that the water inlet pipe can rotate freely in the sleeve. The spray barrel is connected to the bottom end of the water inlet pipe through threads, and it is ensured that the two are tightly connected so that the epoxy resin can flow smoothly from the water inlet pipe into the spray barrel. The upper cover and the lower cover are respectively fixed to the upper and lower ends of the sleeve by bolts to form a closed environment to protect the internal components and prevent debris from entering. The epoxy resin flows from the outlet pipe from top to bottom at high speed, and the water flow power is used to make the water inlet pipe and the spray barrel start to rotate in the sleeve, so that the spray holes on the outer wall of the spray barrel start to evenly spray water or paint to the surroundings, thereby performing all-round spray repair on the well wall and bottom.

[0007] In the above technical solution, further, the self-rotating component includes: a mounting rod, a plurality of fixing rods are provided circumferentially on the outer wall of the mounting rod, one end of the fixing rod is fixedly connected to the outer wall of the mounting rod, and the other end is connected to the inner wall of the water inlet pipe, and blades are provided between the fixing rods.

[0008] In this technical solution, epoxy resin is sprayed into the water inlet pipe at high pressure through the outlet pipe, and then flows along the inside of the water inlet pipe and impacts the blades. After the blades are impacted by the epoxy resin liquid, a rotational torque is generated. This torque is transmitted to the mounting rod and the water inlet pipe through the fixed rod, thereby driving the water inlet pipe to start rotating in the sleeve. As the water inlet pipe rotates, the spray barrel also rotates, and the spray holes on its outer wall begin to evenly spray water or paint all around.

[0009] In the above technical solution, further, limiting rings are provided at the upper and lower ends of the outer wall of the water inlet pipe, and limiting blocks are provided at the inner ends of the upper cover and the lower cover.

[0010] In the above technical solution, further, a first sealing ring is provided between the lower cover and the spray barrel.

[0011] In this technical solution, the sealing performance between the lower cover and the spray barrel is improved to avoid water leakage.

[0012] In the above technical solution, further, a threaded seat is provided on the top of the upper cover, and the upper cover is threadedly connected to the water outlet pipe through the threaded seat.

[0013] In the above technical solution, further, a second sealing ring is provided between the upper cover and the top end of the water inlet pipe to ensure the sealing of the upper cover and prevent the epoxy resin from entering the interior of the sleeve and causing waste of the epoxy resin.

[0014] The beneficial effect of the utility model is that epoxy resin flows from the water outlet pipe from top to bottom at a high speed, and the water flow power is used to make the water inlet pipe and the spray barrel start to rotate in the sleeve, so that the spray holes on the outer wall of the spray barrel start to spray water or paint evenly in all directions, thereby performing all-round spray repair on the well wall and the well bottom.

The water inlet pipe 8 is movably connected to the sleeve 1 through the bearings 13 at both ends to ensure that the water inlet pipe 8 can rotate freely in the sleeve 1. The spray barrel 4 is connected to the bottom end of the water inlet pipe 8 through threads, and ensure that the two are tightly connected so that the epoxy resin can flow smoothly from the water inlet pipe 8 into the spray barrel 4. The upper cover 2 and the lower cover 3 are respectively fixed to the upper and lower ends of the sleeve 1 by bolts 6 to form a closed environment to protect the internal components and prevent debris from entering. The epoxy resin flows from the outlet pipe from top to bottom at a high speed, and the water flow power is used to make the water inlet pipe 8 and the spray barrel 4 start to rotate in the sleeve 1, so that the spray holes 5 on the outer wall of the spray barrel 4 start to evenly spray water or paint to the surroundings, thereby performing all-round spray repair on the well wall and bottom.
