[0061] A plurality of holes are formed in the spray head three-way clamping groove 131, a plurality of insertion columns are arranged on the surface of the fastening part 133 facing the spray head three-way clamping groove 131, and the insertion columns are matched with the holes. When the spray head three-way 132 is fixed, the insertion columns of the fastening part 133 are inserted into the holes, and the insertion columns play a role of a reinforcing bar, and the reinforcing bar can pull the two sides of the fairing main body 12 tightly.

[0062] It can be understood that, by increasing the reinforcing bar (which has the same shape as the fixing part), the advantages are that the overall shape of the fairing is prevented from being loose, the steel sheet is tightly wrapped, and the two sides of the fairing main body are pulled tightly. The fairing main body and other accessories are prevented from being not tightly connected, being easily loose and deformed.

[0063] Please see Figure 5The spray head tee joint 132 includes a tee joint body 1321 having a hollow portion 1322 for fluid to pass through, the tee joint body 1321 also has a socket 1324 for installing the spray head, which is in communication with the hollow portion 1322, to fix the spray head 14, and the tee joint body 1321 also has a limiting block 1323 arranged on the tee joint body 1321.

[0064] It should be noted that the spray mode of the spray head 14 is continuous spraying, intermittent spraying or alternating spraying. Preferably, the spray mode is continuous spraying, and the second choice is intermittent spraying or alternating spraying. The shape of the liquid sprayed by the spray head is parallel fan spraying, conical fan spraying or wave fan spraying. Preferably, the shape is parallel fan spraying, and the second choice is conical fan spraying or wave fan spraying. The spray angle of the spray head to the glass is 10° to 50°. Preferably, the spray angle of the spray head to the glass is 10° to 50°. The second choice is that the spray angle of the spray head to the glass is 5° to 90°. The direction of the liquid sprayed by the spray head is backward, forward, forward and downward, vertically downward, sideways, sideways and downward, or vertically sideways. Preferably, the spray direction is backward (downward), and the second choice is forward, forward and downward, vertically downward, sideways, sideways and downward, or vertically sideways. The distance from the spray head to the glass surface is 30mm to 80mm. The flow rate of each spray head per 10 seconds is 25ml to 80ml. The second choice is that the flow rate of each spray head per 10 seconds is more than 80ml, and the second choice is that the flow rate of each spray head per 10 seconds is 10ml to more than 10ml.

The second choice is that the flow rate of each spray head per minute is more than 480ml, and the second choice is that the flow rate of each spray head per minute is 50ml to 150ml.

[0065] It should be noted that the present application also solves the technical problem of unreasonable connection of the base tee joint and the base in the prior art. The principle is that a limiting groove 164 is arranged at the corresponding end of the pipe body 161 and the base tee joint 22, and a limiting block 1323 matched with the limiting groove 164 is arranged correspondingly. The limiting block and the limiting groove are matched to limit the angle, so that the limiting is accurate and firm, and displacement and rotation are avoided.

[0067] As shown in Figure 6As shown, the connecting pipe 16 has a circular pipe body 161, the two ends of the pipe body 161 have a first port 162 and a second port 163, a limiting groove 164 is opened at the end of the pipe body 161 corresponding to the base tee joint 22, and the limiting groove 164 is matched with the limiting block 1323.

[0068] Optionally, the connecting pipe 16 is circular. It should be noted that the benefits of changing the shape of the two side connecting pipes 16 to circular are that when the nozzle tee joint and the base tee joint are connected with the fairing main body, the assembly is easier, the connection is tight, there is no water leakage, and the nozzle tee joint is accurately limited.

[0069] As shown in the accompanying drawings, Figure 8 , Figure 9 As shown in the accompanying drawings, the front and back of the base tee joint 22 are respectively provided with a first baffle 221 and a second baffle 222, and the first baffle 221 and the second baffle 222 both have a blocking surface; the base 21 includes a base main body 211 located between the first baffle 221 and the second baffle 222, and the front and back of the base main body 211 both have a bearing surface, and the blocking surfaces of the first baffle 221 and the second baffle 222 abut against the bearing surface. In this way, the front and back directions of the base tee joint 22 and the base 21 are limited, preventing the displacement of the base tee joint 22 and the base 21 in the front and back directions, improving stability, and preventing loosening.

[0070] A groove 215 is opened in the bearing surface of the base main body 211 at a position corresponding to the first baffle 221 and the second baffle 222 of the base tee joint 22, and the first baffle 221 and the second baffle 222 are both inserted into and matched with the groove 215. The left and right directions of the base tee joint 22 and the base 21 are limited, preventing the displacement of the base tee joint 22 and the base 21 in the left and right directions, improving stability, and preventing loosening.

[0071] Please continue to refer to Figure 8 , the base 21 further includes a first insertion slot 212 and a second insertion slot 213 located at the top left and right sides of the base main body 211 and located inside the middle part of the base, and the first insertion slot 212 and the second insertion slot 213 form a first limited space and a second limited space respectively between the base main body 211; the left and right sides of the base tee joint 22 are provided with a first insertion sheet 223 and a second insertion sheet 224, and the first insertion sheet 223 and the second insertion sheet 224 are located in the first limited space and the second limited space respectively. The base tee joint 22 and the base 21 are limited in the up and down directions, preventing the displacement of the base tee joint 22 and the base 21 in the up and down directions, improving stability, and preventing loosening.

[0072] Please continue to refer to Figure 8The first baffle 221 and the second baffle 222 are staggered. This staggered arrangement not only increases the width of the limiting surface but also improves the overall structural stability.
