[0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. The structure of a tunnel consists of two parts: the main building and auxiliary equipment. During the construction of a tunnel, it is necessary to use a sprinkler on the top to moisten the cement on the inner wall of the tunnel to avoid cracking of the cement due to rapid drying. At the same time, the sprinkler can also be used to adjust the temperature and humidity in the tunnel, and to extinguish open flames. The common tunnel top sprinkler equipment is generally a sprinkler pipe;

[0003] During the construction of the tunnel top, the existing sprinkler equipment mostly requires workers to push the equipment to move in the tunnel.

DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 3 as well as Figure 4 As shown, in an embodiment of the utility model, a tunnel top watering device includes:

[0028] There are multiple groups of water spray pipes 6, which are fixedly installed on the upper part of the tunnel through fixing parts. Multiple groups of water diverter valves 8 are installed at the bottom of the water spray pipes 6, and each group of water diverter valves 8 is connected to a group of rotating water spraying mechanisms 9;

[0029] A water supply pipe group, one end of which is connected to the pump device 3, and the other end is connected to one end of the corresponding water spray pipe 6, and the water supply pipe group is used to transport the liquid pumped by the pump device 3 to the corresponding water spray pipe 6;

[0030] The rotary sprinkler mechanism 9 includes a housing 901, a bearing 902 is connected to the top surface of the housing 901, a threaded column 903 is fixedly connected to the top of the bearing 902, a sealing gasket 904 is placed on the top of the bearing 902, and a plurality of groups of nozzles 905 are connected to the side of the housing 901 near the bottom, and a counterweight block 906 is fixedly connected to the center of the nozzle 905;

[0031] Specifically, when the rotary sprinkler mechanism 9 of the utility model is in use, it cooperates with the counterweight block 906 and the nozzle 905 to form a partial gravity structure. At the same time, the bearing 902 and the shell 901 are cooperated, and the impact of the water flow is used to make the rotary sprinkler mechanism 9 rotate and spray, which is very convenient. At the same time, the sealing gasket 904 is used for sealing to prevent the water flow from affecting the rotation of the bearing 902. At the same time, the water flow is concentrated through the inner cavity of the threaded column 903, reducing hydraulic consumption and providing sufficient power for the rotary sprinkler mechanism 9, thereby completing comprehensive and uniform watering of the tunnel top.

[0032] like Figure 1 and Figure 5 As shown, in an embodiment of the utility model, the water supply pipe group includes multiple groups of water supply main pipes 1 and multiple groups of water supply branch pipes 5. One end of the water supply main pipe 1 is connected to the water outlet of the pump equipment 3, and the other end is provided with a adapter for connecting multiple groups of water supply branch pipes 5. The water supply branch pipes 5 are connected to the corresponding water spray pipes 6.

[0033] Furthermore, a valve body 10 is fixedly connected to the bottom end of the water supply main pipe 1, and a pressing column 11 is fixedly sleeved on one side of the valve body 10, so that water can flow into the water supply branch pipe 5 through the pressing column 11 and the valve body 10, and then flow into the water spray pipe 6.

[0034] like Figure 4 As shown, in the embodiment of the utility model, a protective shell 2 is installed on the outside of the pump device 3, and a base 4 is welded and installed on the bottom of the pump device 3. Furthermore, the water flow is pressurized by the pump device 3, processed and transported to the water supply main 1, and the protective shell 2 and the base 4 are used to perform external protection and stable installation of the pump device 3.

[0035] like Figure 2 as well as Figure 3 As shown, in the embodiment of the utility model, the bearing 902 is detachably connected to the water diversion valve 8 via a threaded column 903 , and the bearing 902 and the housing 901 are tightly welded.

Through the relationship between the interface tubes inside the shell 901 and the nozzles 905, they can be replaced in later use, which is very convenient.

[0037] Furthermore, the counterweight block 906 forms a rotating structure through the shell 901, bearing 902, nozzle 905 and threaded column 903, and the nozzle 905 is rotated by using the counterweight block 906 and bearing 902. At the same time, the three groups of nozzles 905 form a eccentric gravity structure through the counterweight block 906, and the eccentric gravity structure can be rotated by the impact of the water flow.

[0038] like Figure 2 As shown, in the embodiment of the utility model, the fixing part is a U-shaped fixing device 7, and the U-shaped fixing device 7 is fixedly installed on the top of the tunnel by bolts, and the U-shaped fixing device 7 is provided with a mounting groove adapted to the outer arc of the water spray pipe 6, and the U-shaped fixing device 7 is made of stainless steel. In the utility model, the electrical components that appear are all connected to the external main controller and the 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0039] Based on the above, the working process of the utility model is as follows:

[0040] Connect one side of the pump device 3 to the water flow, pressurize the water flow through the pump device 3, then open the valve body 10 by pressing the column 11 to allow the water flow to enter the water supply main pipe 1, and then separate the water flow through the three rows of water supply branch pipes 5 fixed on the top of the tunnel to flow into the water spray pipe 6, and then let the water flow into the threaded column 903 through the water diversion valve 8 on the bottom of one side of the water spray pipe 6, and then flow into the shell 901, and then let the water flow into the nozzle 905 through the three holes opened in the shell 901, and at the same time use the impact of the water flow to make the eccentric gravity of the nozzle 905 The structure cooperates with the bearing 902 to realize the rotation function, and then the water flow can be further pressurized through the small holes inside the nozzle 905. At the same time, the umbrella-shaped nozzle on the top of the nozzle 905 can control the water flow to spray water on the top of the tunnel over a larger area. The three rows of water pipes 6 and the three groups of nozzles 905 can be set up to spray water on the tunnel comprehensively, thereby improving the work efficiency of the construction. The multiple detachable designs facilitate the early installation and later maintenance, and the cooperation of the valve body 10 and the pressing column 11 can achieve a fully automatic watering function, which is very convenient.
