DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0034] Embodiment one

[0035] Please refer to Figures 1-14The application provides a technical scheme: a water storage type cement base layer watering and curing device, which comprises a watering pipe 1, a plurality of spray heads 2, two transmission rods 3, a water pump 4 and a motion control assembly 5. The two transmission rods 3 are arranged at two ends of the watering pipe 1 respectively, and the inside of any one of the transmission rods 3 is provided with a water storage cavity 31. The output end of the motion control assembly 5 is connected with the top of the transmission rod 3, and the motion control assembly 5 comprises a bearing vehicle 51, an electric telescopic rod 52, a bearing frame 53, a motor 54 and a transmission shaft 55. The two transmission rods 3 are fixedly arranged at the middle part of the transmission shaft 55, and the transmission shaft 55 is connected with the output end of the motor 54. When the device is used, the water storage cavity 31 is first filled with water through the main water pipe at the top of the side wall of the transmission rod 3, then the bearing vehicle 51 can move the device to a designated position, at this time, the transmission rod 3 is in a vertical state, and the watering pipe 1 is located above the cement base layer 8. Then the water pump 4 works to deliver the water in the water storage cavity 31 to the watering pipe 1, and the plurality of spray heads 2 spray water to the cement base layer 8. At the same time, the motion control assembly 5 works, the motor 54 drives the transmission rod 3 to rotate to an inclined state, thereby driving the watering pipe 1 and the plurality of spray heads 2 to move in the horizontal direction, so as to increase the range of water spraying of the spray heads 2, and thus the watering and curing operation on a larger area of the cement base layer 8 can be completed. The output end of the electric telescopic rod 52 is shortened, the bearing frame 53 drives the motor 54, the transmission shaft 55 and the transmission rod 3 to move downward, so that the distance between the watering pipe 1 and the plurality of spray heads 2 and the cement base layer 8 remains unchanged during the horizontal movement, so as to ensure that each position on the top of the cement base layer 8 can be uniformly sprayed by the spray heads 2. When the watering and curing process is completed, the water pump 4 stops working, the output end of the motor 54 reverses, and the output end of the electric telescopic rod 52 is lengthened, so that the watering pipe 1 and the transmission rod 3 move reversely and reset.

[0036] Example two

[0037] On the basis of example one, please refer to Figures 1-3 and Figure 6 The motor 54 and the transmission shaft 55 can also be increased to two, so that the watering pipe 1 can also be increased to two. When the motion control assembly 5 works, the two motors 54 drive the two transmission shafts 55 to rotate in opposite directions, so that the two watering pipes 1 move in opposite directions. Therefore, the range of water spraying of the spray heads 2 can be further expanded, and the time for completing the watering and curing operation on the cement base layer 8 can be shortened.

[0038] Example three

[0039] On the basis of example one, please refer to Figures 1-3 , Figure 7 and Figures 9-14The upper portion of the sprinkling pipe 1 is provided with a direction control assembly 6. The two ends of the sprinkling pipe 1 are rotationally connected with two transmission rods 3 respectively, the output end of the direction control assembly 6 is connected with the sprinkling pipe 1, the direction control assembly 6 can drive the sprinkling pipe 1 to rotate, thereby adjusting the angle of the plurality of spray heads 2. In the case of no wind, the plurality of spray heads 2 always face the cement base layer 8, and the water sprayed by the spray heads 2 falls vertically on the cement base layer 8. In the case of wind, the plurality of spray heads 2 spray water obliquely to offset the wind force, and still ensure that the water sprayed by the spray heads 2 falls vertically on the cement base layer 8.

[0040] Please refer to Figure 3 、 Figure 7 and Figures 9-14 The direction control assembly 6 comprises a gear 61, a rack 62 and a position adjusting assembly 63. The gear 61 is sleeved on the outer surface of the sprinkling pipe 1, the rack 62 is in meshing transmission with the gear 61, and the output end of the position adjusting assembly 63 is connected with the rack 62. When the position adjusting assembly 63 drives the rack 62 to move upward or downward along the length extension direction of the transmission rod 3, the rack 62 can drive the gear 61 to rotate forward or reversely, thereby driving the sprinkling pipe 1 to rotate forward or reversely, so as to change the angle of the spray heads 2.

[0041] In the embodiment, the transmission rod 3 is further provided with a sensor assembly (not shown in the sensor assembly diagram), which comprises a wind direction sensor, an stm32 controller, a temperature and humidity sensor and a water outlet electromagnetic valve. The wind direction sensor can intuitively obtain the wind direction and the size of the wind force, so as to the working state of the direction control assembly 6, control the rotation angle of the sprinkling pipe 1, and make the plurality of spray heads 2 play the best spraying effect. The temperature and humidity sensor sends a signal to the stm32 controller according to the temperature and humidity of the on-site environment, and the stm32 controller opens the water outlet electromagnetic valve and starts the water pump 4, so as to deliver the water in the water storage cavity 31 to the sprinkling pipe 1, and spray through the plurality of spray heads 2. The sensor assembly can intelligently adjust the spraying water amount, so as to realize the effect of intelligent and accurate maintenance.

[0042] Please refer to Figures 4-5 and Figures 7-14, the inside of the water storage cavity 31 is also provided with a first assembly cavity 32, the position adjusting assembly 63 comprises a pressing rod 631 and a pressing disc 632, when the water in the water storage cavity 31 enters the first assembly cavity 32, the pressing disc 632 can be pushed to move downwards, and then the rack 62 is driven to move downwards by the pressing rod 631, so that the sprinkling pipe 1 rotates forward. When the water in the first assembly cavity 32 leaves the first assembly cavity 32, the pressing rod 631 and the rack 62 can move upwards together, so that the sprinkling pipe 1 reverses. The water storage cavity 31 is provided with a partition plate 33, the partition plate 33 and the inner wall of the water storage cavity 31 jointly form a water distribution cavity 34, and the water distribution cavity 34 is provided with a water pushing assembly 7. The water in the water storage cavity 31 will first enter the water distribution cavity 34, and then the water pushing assembly 7 will transport the water in the water distribution cavity 34 into the first assembly cavity 32, so that the sprinkling pipe 1 rotates forward. The water pushing assembly 7 can also suck the water in the first assembly cavity 32 back into the water distribution cavity 34, so that the sprinkling pipe 1 reverses.

[0043] Please refer to Figures 4-5 and Figures 7-14 , the side wall and the bottom of the partition plate 33 are respectively provided with a first through hole 331 and a second through hole 332, and the first assembly cavity 32 and the water distribution cavity 34 are communicated through a water conveying channel 35. The lower portion of the first assembly cavity 32 is provided with a second assembly cavity 36, the position adjusting assembly 63 further comprises a pressing plate 633 and a spring 634, and the water pushing assembly 7 comprises an electric push rod 71, a water blocking block 72 and a plug rod 73. When the sprinkling pipe 1 does not need to be driven to rotate, the output end of the electric push rod 71 is in a shortened state, and the first through hole 331 and the second through hole 332 are not blocked. At this time, the water in the water storage cavity 31 can enter the water distribution cavity 34 through the first through hole 331, and fill the space below the water blocking block 72, and the water in the water distribution cavity 34 can also enter the first assembly cavity 32 through the water conveying channel 35, and the spring 634 can apply a counter force to the pressing plate 633, so that the pressure of the water in the first assembly cavity 32 to the pressing disc 632 cannot drive the pressing rod 631 and the rack 62 to move, and the pressing rod 631 and the rack 62 will remain stationary, and the sprinkling pipe 1 will not rotate.

[0044] Please refer to Figures 1-14When the sprinkler 1 needs to be driven to rotate, the output end of the electric push rod 71 is elongated, driving the water stop block 72 and the insertion rod 73 to move downward together, the water stop block 72 blocks the first through hole 331, and the insertion rod 73 blocks the second through hole 332, so that the water distribution cavity 34 and the water storage cavity 31 are no longer in communication. As the output end of the electric push rod 71 is continuously elongated, the space below the water stop block 72 in the water distribution cavity 34 becomes smaller and smaller, and the water in the water distribution cavity 34 is pushed by the water stop block 72 into the water delivery channel 35 and finally into the first assembly cavity 32. As more and more water enters the first assembly cavity 32, the pressure exerted by the water on the pressure plate 632 becomes larger and larger, and the pressure plate 632 can drive the rack 62 to move downward through the pressure rod 631, so that the sprinkler 1 rotates forward. In this process, the pressure plate 632 slides along the inner wall of the first assembly cavity 32, the pressure plate 633 slides along the inner wall of the second assembly cavity 36, the pressure plate 633 exerts pressure on the spring 634, and the spring 634 is compressed to store elastic potential energy. Therefore, in the absence of wind, the plurality of nozzles 2 can always face the cement base layer 8, and the water sprayed by the nozzles 2 falls vertically on the cement base layer 8.

[0045] Please refer to Figures 1-14 In the presence of wind, the wind direction will change constantly, at this time the output end of the electric push rod 71 is elongated or shortened in real time, if the space below the water stop block 72 in the water distribution cavity 34 decreases, the water in the first assembly cavity 32 will increase accordingly, if the space below the water stop block 72 in the water distribution cavity 34 increases, the water in the first assembly cavity 32 will return to the water distribution cavity 34, and the water in the first assembly cavity 32 will decrease. When the water in the first assembly cavity 32 increases, the sprinkler 1 can continue to rotate forward, and when the water in the first assembly cavity 32 decreases, the spring 634 releases the elastic potential energy to elongate, and through the pressure plate 633, the pressure rod 631 and the rack 62 can be driven to move upward together, so that the sprinkler 1 reverses. The orientation of the plurality of nozzles 2 will change in real time, and the inclined water spray will offset the wind force, still ensuring that the water sprayed by the nozzles 2 falls vertically on the cement base layer 8.

[0046] Please refer to Figures 1-14The inside of the transmission rod 3 is further provided with a first air channel 37 and a second air channel 38. One end of the first air channel 37 penetrates the top side wall of the transmission rod 3, and the other end communicates with the space above the water separation block 72 in the water separation cavity 34. The two ends of the second air channel 38 respectively communicate with the first assembly cavity 32 and the second assembly cavity 36. When the output end of the electric push rod 71 is extended, external air can enter the water separation cavity 34 through the first air channel 37, and the air in the first assembly cavity 32 can enter the second assembly cavity 36 through the second air channel 38. When the output end of the electric push rod 71 is shortened, the air in the water separation cavity 34 can be discharged from the transmission rod 3 through the first air channel 37, and the air in the second assembly cavity 36 can return to the first assembly cavity 32 through the second air channel 38. Therefore, the air in the water separation cavity 34 does not hinder the movement of the water separation block 72, and the air in the first assembly cavity 32 does not hinder the movement of the pressure plate 632.
