[0042] like Figure 1 and 6 As shown in 12, the first screw rod 6 drives the first active bevel gear 20 to rotate, the first active bevel gear 20 drives the first driven bevel gear 39 to rotate, and the first driven bevel gear 39 drives the sleeve rod 10 to rotate. Since the sleeve rod 10 is provided with a spline corresponding to the sleeve 21, the sleeve rod 10 can drive the sleeve 21 to rotate without affecting the sliding between the two, and the sleeve rod 10 is limitedly set on the sliding bracket 3, and can slide on the inner wall of the sleeve 21 as the sliding bracket 3 slides.

[0043] A slider 30 is provided at the upper end of the support plate 2, and a second screw barrel 40 is fixedly connected to the inner wall of one end of the slider 30. A second screw rod 29 threadably matched with the second screw barrel 40 is rotatably connected to the support plate 2, and a friction wheel 28 sleeved on the sleeve 21 is rotatably connected to the other end of the slider 30.

[0044] like Figure 6 and 7 As shown in FIG. 8 , the sleeve 21 rotates to drive the friction wheel 28. Since the friction wheel 28 is in contact with the conical friction cylinder 22 and is frictionally connected, the friction wheel 28 can drive the conical friction cylinder 22 to rotate, and the conical friction cylinder 22 drives the second active bevel gear 32 to rotate. The second active bevel gear 32 drives the second driven bevel gear 31 to rotate, and the second driven bevel gear 31 drives the rotating shaft rod 23 to rotate. During the circumferential rotation of one end of the rotating shaft rod 23, the first connecting rod 24 drives the swing rod 25 to deflect with the rotating pin 27 provided in the middle thereof as the axis. During the deflection of the swing rod 25 to one end, it drives the second connecting rod 26 to deflect. The second connecting rod 26 drives the sliding bracket 3 to slide back and forth, and cooperates with the sliding along the other horizontal direction of the sliding bracket 3, thereby realizing the range spraying of the nozzle 13, and it can also be achieved through By changing the contact position between the friction wheel 28 and the conical friction cylinder 22, the rotation speed of the conical friction cylinder 22 is adjusted. A handle 19 is provided at one end of the second screw 29, and the second screw 29 is driven to rotate by the handle 19. During the rotation process, the second screw 29 is threadedly engaged with the second screw cylinder 40 at one end of the slider 30, thereby driving the slider 30 to slide along the axial direction of the second screw 29. When the friction wheel 28 is closer to the thick end of the conical friction cylinder 22, the rotation speed of the friction wheel 28 is fixed, and the rotation speed of the conical friction cylinder 22 is lower, thereby adjusting the rotation speed of the shaft rod 23, changing the deflection frequency of the swing rod 25, and then adjusting the speed and frequency of the reciprocating horizontal sliding of the sliding bracket 3. According to different high temperature weather conditions, the spraying speed and frequency can be adjusted to improve the cooling effect and avoid cracking of the concrete.

[0045] Limiting rods 17 are respectively provided on both sides of the lower end of the sliding bracket 3 to limit the sliding movement with the supporting sliding rod 4 .

[0046] like Figure 3As shown, the limiting rods 17 are respectively arranged at both ends of the supporting slide bar 4 to ensure that the sliding bracket 3 slides horizontally along the axial direction of the supporting slide bar 4 under the action of the limiting rods 17 .

[0047] The height adjustment structure also includes a hydraulic cylinder 33 fixedly connected to the base plate 1, and the output end of the hydraulic cylinder 33 is fixedly connected to a sliding block 34. The two ends of the base plate 1 are respectively provided with a first support rod 35 and a second support rod 36 which are cross-rotatably connected. The lower end of the first support rod 35 is provided with a sliding pin 38 which is slidably connected to the inner wall of the base plate 1, the upper end of the first support rod 35 is provided with a fixed rotation pin 37 which is fixedly connected to the support plate 2, the lower end of the second support rod 36 is provided with the fixed rotation pin 37 which is fixedly connected to the base plate 1, the upper end of the second support rod 36 is provided with the sliding pin 38 which is slidably connected to the inner wall of the support plate 2, and the sliding pin 38 at the lower end of the first support rod 35 is coaxially rotatably connected to the two ends of the sliding block 34.

[0048] like Fig. 9 and 10 As shown, the hydraulic cylinder 33 is controlled to work according to the concrete pouring height of the substation, and the output end of the hydraulic cylinder 33 drives the sliding block 34 to slide along the upper end surface of the base plate 1, and the sliding block 34 drives the sliding pins 38 at both ends of the first support rod 35 to slide along the inner wall of the base plate 1 respectively. Since the first support rod 35 and the second support rod 36 are rotated in the middle, and the same side of the first support rod 35 and the second support rod 36 are respectively limited on the support plate 2 and the base plate 1 by the fixed rotation pin 37, when the first support rod 35 is driven in the center with the sliding pin 38, the angle between the first support rod 35 and the second support rod 36 becomes smaller, and the upper ends of the first support rod 35 and the second support rod 36 extend upward, thereby driving the support plate 2 to rise, and then adjusting the height of the support plate 2, and since the nozzle 13 is provided with the lower end of the sliding bracket 3 at one end of the support plate 2, the spraying height of the nozzle 13 is adjusted to adapt to the pouring height of the substation concrete.

[0049] The working process of the present invention is as follows: when the present invention is in use, the hydraulic cylinder 33 is controlled to work according to the concrete pouring height of the substation, the output end of the hydraulic cylinder 33 drives the sliding block 34 to slide along the upper surface of the bottom plate 1, and the sliding block 34 drives the sliding pins 38 at both ends of the first support rod 35 to slide along the inner wall of the bottom plate 1 respectively. Since the first support rod 35 and the second support rod 36 are rotated in the middle, and the same side of the first support rod 35 and the second support rod 36 are respectively limited on the support plate 2 and the bottom plate 1 by the fixed rotation pin 37 Therefore, when the first support rod 35 is driven in the center along with the sliding pin 38, the angle between the first support rod 35 and the second support rod 36 becomes smaller, and the upper ends of the first support rod 35 and the second support rod 36 extend upward, thereby driving the support plate 2 to rise, and then adjusting the height of the support plate 2. Since the nozzle 13 is arranged at the lower end of the sliding bracket 3 at one end of the support plate 2, the spraying height of the nozzle 13 is adjusted to adapt to the pouring height of the substation concrete, and to perform a wide range spraying on the concrete poured on the substation.

[0050] The motor 5 is working, and the output end of the motor 5 drives the first screw 6 to rotate. The first screw 6 is threadedly matched with the first screw barrel 18 on the inner wall of the rotating shaft block 11, thereby driving the mounting turntable 7 at the lower end of the rotating shaft block 11 to slide horizontally along the axial direction of the sliding bracket 3. During the process of the mounting turntable 7 driving the surrounding gear 8 to slide horizontally, the surrounding gear 8 is meshed with the spur rack 9, thereby realizing that the surrounding gear 8 moves horizontally and rotates at the same time, and the mounting turntable 7 drives the fixed shaft block 16 to rotate and move horizontally, and the fixed shaft block 16 drives the mounting tube 12 to rotate and move horizontally, and the mounting tube 12 drives the nozzle 13 to realize range spraying, thereby improving the spraying range.

[0051] At the same time, the first screw rod 6 drives the first active bevel gear 20 to rotate, the first active bevel gear 20 drives the first driven bevel gear 39 to rotate, and the first driven bevel gear 39 drives the sleeve rod 10 to rotate. Since the sleeve rod 10 is provided with a spline corresponding to the sleeve 21, the sleeve rod 10 can drive the sleeve 21 to rotate without affecting the sliding between the two, and the sleeve rod 10 is limited on the sliding bracket 3 and can slide on the inner wall of the sleeve 21 as the sliding bracket 3 slides. The sleeve 21 rotates and drives the friction wheel 28. Since the friction wheel 28 is in contact with the conical friction cylinder 22 and is frictionally connected, the friction wheel 28 can drive the conical friction cylinder 22 to rotate, and the conical friction cylinder 22 drives the second active bevel gear 32 to rotate, and the second active bevel gear 32 drives the second driven bevel gear 31 to rotate, and the second driven bevel gear 31 drives the rotating shaft rod 23 to rotate. During the circumferential rotation of one end of the rotating shaft rod 23, the first connecting rod 24 drives the swing rod 25 with the rotating pin 2 provided in the middle thereof. 7 is the axis for deflection, and the swing rod 25 drives the second connecting rod 26 to deflect during the deflection to one end, and the second connecting rod 26 drives the sliding bracket 3 to slide back and forth, and the rotation speed of the conical friction cylinder 22 can also be adjusted by changing the contact position between the friction wheel 28 and the conical friction cylinder 22. A rotating handle 19 is provided at one end of the second screw rod 29, and the second screw rod 29 is driven to rotate by the rotating handle 19. During the rotation process, the second screw rod 29 is threadedly engaged with the second screw cylinder 40 at one end of the sliding block 30, thereby driving the sliding block 30 to slide axially along the second screw rod 29. When the friction wheel 28 is closer to the thick end of the conical friction cylinder 22, the rotation speed of the friction wheel 28 is fixed, and the rotation speed of the conical friction cylinder 22 is lower, thereby adjusting the rotation speed of the rotating shaft rod 23, changing the deflection frequency of the swing rod 25, and then adjusting the speed and frequency of the reciprocating horizontal sliding of the sliding bracket 3. According to different high temperature weather, the speed and frequency of spraying can be adjusted to improve the cooling effect and avoid cracking of concrete.
