[0026] like Figures 1-6 As shown, the semi-automatic circular sprayer for wells provided in this embodiment includes a first housing 1, an annular pipe 2 on the outer side of the first housing 1, an atomizing nozzle 9 connected to the bottom of the annular pipe 2, a water outlet pipe 3 connected between the first housing 1 and the annular pipe 2, a water inlet pipe 4 fixedly connected to the outer wall of the first housing 1, a second housing 5 connected to the bottom of the first housing 1, a first rotating shaft 6 rotatably mounted on the inner side of the first housing 1, an impeller 7 located inside the first housing 1 connected to the outer wall of the first rotating shaft 6, the bottom end of the first rotating shaft 6 extending to the inner side of the second housing 5, and a plurality of fans 8 rotatably connected to the second housing 5 are driven and connected. With the arrangement of the first housing 1, the annular pipe 2, the outlet pipe 3, and the inlet pipe 4, the inlet pipe 4 is connected to an external water source. Water flows into the first housing 1 to form a circulation, and then flows from the outlet pipe 3 into the annular pipe 2. It is sprayed out through the atomizing nozzle 9 to form water mist for dust suppression. With the arrangement of the first rotating shaft 6, the impeller 7, and the fan 8, the water flow in the first housing 1 drives the impeller 7, which in turn drives the first rotating shaft 6 to rotate, thereby driving the fan 8 to work. This can diffuse the water mist, thereby expanding the effective coverage area and improving the dust suppression effect of spraying. This device can achieve the function of diffusing water mist without the need for an external power source, which is energy-saving and environmentally friendly.

Multiple annular pipes 2 are provided, all interconnected via the outlet pipe 3. The eccentric connection of the outlet pipe 3 and the inlet pipe 4 to the first housing 1 improves the circulation effect, thereby providing sufficient power to the impeller 7. The arrangement of multiple annular pipes 2 expands the effective coverage area of ​​the spray.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the top of the first box 1 is bolted with a sealing cover 10, the top of the sealing cover 10 is connected with a mounting rack 11, the top of the first box 1 is provided with an outer edge, a first connecting hole 16 matched with the bolt is formed on the outer edge, the sealing cover 10 is provided with a second connecting hole 17 corresponding to the first connecting hole 16, and the first box 1 and the second box 5 are connected with a connecting rod 18. Through the arrangement of the mounting rack 11, the device can be installed and fixed; through the arrangement of the connecting rod 18, the first box 1 and the second box 5 are not directly connected, so that water leakage of the first box 1 can not directly enter the second box 5, thereby preventing corrosion.

[0029] In this embodiment, as shown in Figure 2 、 Figure 5 and Figure 6 , four fans 8 are arranged on the four sides of the second box 5, the fan 8 comprises a second rotating shaft 12 rotatably connected with the second box 5, one end of the second rotating shaft 12 located outside the second box 5 is connected with a fan blade 13, one end of the fan 8 located inside the second box 5 is connected with a first gear 14, the bottom end of the first rotating shaft 6 is connected with a second gear 15 matched with the first gear 14, and the fan blade 13 is a plastic fan blade. Through the arrangement of the four fans 8, the circumferential wind force can be uniform, thereby improving the diffusion efficiency of the water mist; the plastic fan blade 13 can prevent corrosion and has a relatively light weight, thereby being convenient to be driven.

[0030] In this embodiment, as shown in Figures 1-6 , the working process of the downhole semi-automatic circular sprayer provided by the embodiment is as follows:

[0031] Step 1: connecting a water source to the water inlet pipe 4, the water flow enters the first box 1 to form a circulating flow, thereby driving the impeller 7 to rotate, and driving the first rotating shaft 6 to rotate;
