Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, and in particular to a bridge concrete tower column curing system. Background Art

[0002] More and more large-span bridges have emerged in mountain valleys. Most of these bridges with strong spanning capacity are suspension bridges and cable-stayed bridges. High-altitude maintenance of concrete has always been a key difficulty for the main towers and tall piers of suspension bridges and cable-stayed bridges. The construction period of tower columns is generally nearly one year, which needs to experience seasonal changes. The tower column concrete is high-strength, high-performance concrete with thick walls and high columns and high hydration heat. In order to prevent cracks in the tower column concrete, concrete maintenance measures are extremely important.

[0003] Due to their unique vertical and upright structures, the area where towers and piers can be wet-cured is relatively small, and the curing processes adopted are not consistent, and the effects vary greatly. Whether the curing process is appropriate is related to the generation of cracks during the construction period of towers and piers. In the construction process of large bridges, due to the large size of the main tower of the bridge and the volume of concrete, water spraying is generally used to cure the surface of the tower after demolding. Because too fast drying during the hardening process will cause cracks, it is necessary to maintain appropriate humidity during the hardening process, that is, the concrete hardening process needs to be cured. Common curing methods include: water storage curing, water spraying curing, wet covering curing, plastic sheeting curing, and spraying curing agents. Basically, they are all for curing the exposed concrete surface. In view of the unique vertical and upright structure of the tower, water spraying is used for curing. Water spraying can ensure that the surface and interior of the concrete maintain the necessary moisture to prevent cracks caused by too fast drying. Compared with other curing methods, such as covering moisture or using chemical curing agents, water spraying curing is relatively simple to operate, easy to implement, and does not require special equipment or materials. Compared with spray curing agents, water spray curing does not involve the use of chemical substances, is environmentally friendly, and does not produce harmful waste or emissions.

[0004] However, since large bridges are built between mountain valleys, in complex mountain valley areas, due to the large terrain undulations, diverse landforms, and extremely complex wind environments, wind parameters at the bridge site are usually collected about a year in advance. Strong winds are easily formed between valleys, and the strong winds formed can easily blow away the spray, causing the water mist to be unable to moisturize the concrete tower column, resulting in poor water spray maintenance of the concrete tower column; if high-speed water flow is always used for spraying, the water consumption for large bridges is too large, resulting in a waste of water resources. Summary of the invention

[0005] In view of the deficiencies in the prior art, the technical problem solved by the present invention is to provide a concrete tower column maintenance system to solve the problem that the canyon wind environment where the existing tall tower columns are located is complex and the spray is easily blown away, resulting in the water mist being unable to moisturize the concrete tower columns, resulting in poor water spray maintenance effect for the concrete tower columns.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is: a concrete tower column maintenance system, including a data monitoring module, an analysis and control module, a data storage module, an automatic water spraying system, a wind field construction module, a canyon wind field prediction module and a meteorological data acquisition module connected in sequence;

[0007] The data monitoring module is used to obtain environmental data in real time and send the environmental data to the analysis and control module. The environmental data includes wind speed, wind direction and humidity parameters;

[0008] The data storage module is used to store the topographic data of the bridge and the collected environmental data;

[0009] The wind field construction module is used to construct canyon wind field information based on terrain data and the wind speed and wind direction data collected at the bridge site;

[0010] The meteorological data acquisition module is used to acquire meteorological data within a future set time period, the meteorological data including wind speed and wind direction parameters, and the canyon wind field prediction module predicts the wind speed and wind direction data at the tower column in a preset time period based on the pre-trained canyon wind field prediction model and the meteorological data and canyon wind field information;

[0011] The automatic water spraying system comprises a controller, an electric three-way valve, a water tank, a water pump, a spray mechanism and a spray mechanism. The controller controls the water pump and the electric three-way valve to work, and the water pump supplies water to the spray mechanism and the spray mechanism respectively through the electric three-way valve.

[0012] The analysis and control module includes an analysis and judgment unit, a wind speed and direction position judgment unit, and a mode switching unit; the analysis and judgment unit is used to judge whether the humidity of the tower column is greater than the set humidity. If the judgment result is yes, the automatic water spraying system is turned off, and if the judgment result is otherwise, the automatic water spraying system is turned on; the wind speed and direction position judgment unit is used to judge whether the wind speed is greater than the set wind speed. If the judgment result is otherwise, no processing is performed. If the judgment result is yes, then further judge whether each side of the tower column is the leeward side according to the wind direction. If the judgment result is no, the mode switching unit controls the automatic water spraying system on this side to work in the spray mode. If the judgment result is yes, then the mode switching unit controls the automatic water spraying system on this side to work in the spray mode.

[0013] The beneficial effect of this solution is: by constructing wind field information and predicting the wind force and wind speed in the future based on meteorological data and wind field information, it is possible to judge whether each side of the bridge tower is on the windward side or the leeward side according to the prediction results, and then intelligently select the spray mode or the spray mode, which can significantly improve the maintenance effect of the concrete tower. For example, when the prediction result shows that the wind speed is high and the side is on the windward side, the system will switch to the spray mode in advance. In this mode, the water flow rate is high and the water droplets are large. Compared with fine mist, it is less likely to be blown away by strong winds, thereby ensuring that the maintenance water can evenly wet the surface of the tower column and achieve the expected maintenance effect. In the case of high wind speed, the leeward side is basically not affected by the wind, so it can still work in the spray mode. When the wind speed decreases, the automatic water spraying system on the windward side will switch back to the spray mode, which not only ensures the maintenance effect of the concrete, but also effectively reduces the amount of maintenance water, realizing resource conservation and efficient utilization.

[0014] Compared with the existing water spraying system that can only be maintained by spraying, it is impossible to ensure that a sufficient amount of water reaches the surface of the concrete tower column evenly in strong wind weather. This solution predicts the wind speed and wind direction data in advance based on wind field information and meteorological data, so that the spraying and spraying working modes can be switched in advance according to the wind speed and wind direction data, effectively responding to the maintenance needs under different wind conditions. In addition, it can also be used in conjunction with the angle adjustment unit to further reduce the impact of wind force and wind direction on the offset of the sprayed water mist or water droplets, thereby improving the accuracy and effect of maintenance. Secondly, determine whether the automatic water spraying system needs to be turned on based on the humidity of the tower column. For example, if the humidity of the concrete surface of the tower column meets the requirements on a rainy day, there is no need to use the automatic water spraying system, saving water.

[0015] Furthermore, it also includes a flow budget module. The data monitoring module is also used to collect water level data of the water tank of the automatic sprinkler system, and obtain the water volume in the water tank based on the current water level data of the water tank. The flow budget module calculates the total amount of spraying of the automatic sprinkler system within a preset time period based on the wind speed data, and determines whether water replenishment is needed based on the total amount of spraying and the water volume in the water tank. If the judgment result is yes, the automatic sprinkler system is controlled to replenish the water tank in advance.

[0016] The predicted wind speed can be used to calculate the water consumption within a preset time period in the future, so that the water tank can be replenished in time to prevent the automatic sprinkler system from being short of water, which would affect the tower column concrete maintenance effect and even cause cracks on the concrete surface, affecting the safety and durability of the structure.

[0017] Furthermore, the automatic sprinkler system also includes an angle adjustment mechanism for adjusting the angle of the nozzle of the sprinkler mechanism or the spray mechanism, and the analysis and control module also includes an angle adjustment unit. The angle adjustment unit is used to calculate the offset and offset angle of the water droplets from the nozzle of the current automatic sprinkler system to the tower column based on the predicted wind direction and wind speed data, and calculate the adjustment direction and adjustment angle based on the offset and the offset angle. The automatic sprinkler system adjusts the nozzle according to the adjustment direction and the adjustment angle.

[0018] Generally, the spray direction of the sprinkler is fixed, and changes in wind direction and speed can easily cause the water droplets to deviate from the target tower column. The angle adjustment unit can calculate the offset and offset angle in real time based on the wind direction and speed data, so that the sprinkler head can make corresponding adjustments to ensure that the water droplets can accurately reach the tower column surface. It can be used as an auxiliary means to deal with strong winds, so that each part of the tower column can be sprayed as evenly as possible, improving the effectiveness of the water spraying operation.

[0019] Furthermore, the data storage module is also used to store the maintenance time of the current tower column spraying section, and the analysis and judgment module is also used to calculate the concrete predicted strength data based on the temperature data and the maintenance time, and judge whether the concrete predicted strength data is greater than the preset spraying intensity limit. If the judgment result is yes, then when it is judged that the wind speed is greater than the set wind speed, the mode switching unit controls the automatic water sprinkler system to operate in the spray mode; if the judgment result is no, then when it is judged that the wind speed is greater than the set wind speed, the mode switching unit still controls the automatic water sprinkler system to operate in the spray mode, and only adjusts the angle of the nozzle of the automatic water sprinkler system by deriving the adjustment direction and adjustment angle through the angle adjustment unit.

[0020] When the concrete strength does not meet the requirements, that is, it is less than the spray intensity limit, the water flow intensity of the spray mechanism is easy to damage the concrete surface, thereby affecting the concrete surface structure of the tower column. Therefore, at this time, the angle adjustment mechanism is used to adjust the angle of the nozzle to prevent the droplets sprayed by the spray system from being too offset and unable to moisturize and cool the tower column surface. When the strength of the concrete reaches or exceeds the required spray intensity limit, it indicates that the concrete has sufficient structural strength to resist the higher water flow pressure. At this time, you can choose whether to enable the spray mode according to the actual wind speed conditions. In the case of high wind speed, the spray mode is more suitable because the water droplets it produces are larger and not easily blown away by the wind, so as to more effectively keep the concrete surface moist. In addition, even when the spray mode is enabled, the angle adjustment mechanism can be used to further optimize the spray angle of the nozzle to cope with the challenges brought by strong winds and ensure that the water can be evenly distributed on the surface of the tower column, so as to achieve the best maintenance effect.

[0021] Furthermore, the water pump is also connected to a variable frequency speed regulator, and the spray mechanism and the mist spray mechanism are both provided with a flow meter, which is electrically connected to the controller. The flow meter is used to monitor the flow velocity and flow rate of water in the pipeline of the spray or mist spray mechanism. The analysis and judgment unit is also used to calculate the flow velocity of the automatic sprinkler system according to the wind speed, and send the flow velocity to the controller of the automatic sprinkler system. The controller is used to control the variable frequency speed regulator to adjust the working frequency of the water pump according to the flow velocity.

[0022] Since the spray water sprayed at high speed is not easily blown away by the wind, the flow rate of the curing water can be controlled according to the wind speed to reduce the deviation effect of the wind speed on the curing water and improve the curing effect. At the same time, when the concrete strength does not meet the requirements of the spray water spraying, the spray flow rate of the spray mechanism can be increased to increase the spray volume, which can also further reduce the deviation effect of the wind speed on the curing water.

[0023] Furthermore, the angle adjustment mechanism includes a fixed bracket, a movable bracket, and a driving rod for driving the movable bracket, the fixed bracket is detachably fixed to the tower column, one end of the driving rod is rotatably connected to the fixed bracket, and the other end is hinged to the movable bracket, the driving rod includes a transverse telescopic rod for driving the movable bracket to move left and right, and a vertical telescopic rod for driving the movable bracket to move up and down; a water pipe is detachably fixed to the fixed bracket, the nozzle is connected to the water pipe through a universal joint and the water outlet faces the surface of the tower column, the movable bracket is provided with a slot, and the movable bracket is located between the fixed bracket and the tower column, the nozzle passes through the slot and is movably connected to the movable bracket; an angle sensor is provided on the nozzle, and the angle sensor and the driving rod are electrically connected to the controller respectively.

[0024] The controller controls the telescopic distance of the horizontal telescopic rod and the vertical telescopic rod, so as to accurately adjust the position of the movable bracket and adjust the angle of the nozzle. Through the cooperation of the movable bracket and the horizontal telescopic rod and the vertical telescopic rod, the angles of multiple nozzles on the same side of the tower column can be adjusted synchronously, with high adjustment efficiency. The structural design of the whole equipment is concise and easy to operate and maintain.

[0025] Furthermore, a retention groove is provided at the lower end of the fixing bracket, which is in close contact with the tower column surface and can be detachably fixed to the tower column. The retention groove is used to collect the maintenance water sprayed from the upper construction section and the possible rust water to prevent affecting the surface structure and appearance of the tower column below.

[0029] The following is further described in detail through specific implementation methods:

[0030] The reference numerals in the drawings of the specification include: tower column 1, fixed support 2, movable support 3, water pipe 4, spray nozzle 41, spray nozzle 42, horizontal telescopic rod 5, vertical telescopic rod 6, and retention groove 7.

[0031] As attached Figure 1 As shown: a concrete tower column maintenance system, including a data monitoring module, an analysis and control module, a data storage module, an automatic water spraying system, a wind field construction module, a canyon wind field prediction module and a meteorological data acquisition module connected in sequence;

[0032] The data monitoring module is used to obtain environmental data in real time and send the environmental data to the analysis and control module. The environmental data includes wind speed, wind direction, humidity and concrete strength parameters;

[0033] The data storage module is used to store the topographic data of the bridge and the collected environmental data;

[0034] The wind field construction module is used to construct canyon wind field information based on terrain data and collected wind speed and wind direction data;

[0035] The meteorological data acquisition module is used to acquire meteorological data within a future set time period, the meteorological data including wind speed and wind direction parameters, and the canyon wind field prediction module predicts the wind speed and wind direction data at the tower column in a preset time period based on the pre-trained canyon wind field prediction model and the meteorological data and canyon wind field information;

[0036] The analysis and control module includes an analysis and judgment unit, a wind speed and direction position judgment unit, and a mode switching unit. The analysis and judgment unit is used to judge whether the humidity of the tower column is greater than the set humidity. If the judgment result is yes, the automatic water spraying system is turned off, and if the judgment result is otherwise, the automatic water spraying system is turned on. The wind speed and direction position judgment unit is used to judge whether the wind speed is greater than the set wind speed. If the judgment result is otherwise, no processing is performed. If the judgment result is yes, then further judge whether each side of the tower column is the leeward side according to the wind direction. If the judgment result is no, the mode switching unit controls the automatic water spraying system on this side to work in the spray mode. If the judgment result is yes, the mode switching unit controls the automatic water spraying system on this side to work in the spray mode.

[0037] By detecting the wind speed, the spray mode or the mist mode can be selected according to the wind speed. When the wind speed is too high, it is switched to the spray mode. The water flow rate of the spray mode is large and the water droplets are large, which is less likely to be blown away by the strong wind. Therefore, the curing water can wet the surface of the tower column, thereby ensuring the curing effect of the system; when the wind speed decreases, it switches back to the spray mode, which can not only ensure the curing effect of the tower column concrete, but also reduce the amount of curing water. Compared with the existing water spray system, only spray curing cannot cope with strong wind weather, and the spray cannot reach the surface of the concrete tower column evenly and in sufficient quantity, affecting the curing effect of the concrete tower column; this scheme can flexibly switch the working modes of spray and spray according to the wind force to resist strong wind and ensure the moisturizing curing effect of the concrete surface; at the same time, it can be used in conjunction with the angle adjustment unit to reduce the offset of the wind force and wind direction on the sprayed water mist or water droplets. The constructed canyon wind field information can be used as a training data set for the prediction model of the canyon wind field prediction module to improve the accuracy of the prediction model. Secondly, the need to turn on the automatic sprinkler system can be determined based on the humidity of the tower column. For example, if the humidity on the concrete surface of the tower column meets the requirement on a rainy day, there is no need to use the automatic sprinkler system, thus saving water.

[0038] The automatic sprinkler system includes a controller, an electric three-way valve, a water tank, a water pump, a spray mechanism and a spray mechanism, wherein the controller, the electric three-way valve, the water tank, the water pump, are not shown in the figure, the spray mechanism and the spray mechanism are arranged in parallel and are located at different heights; the controller controls the operation of the water pump and the electric three-way valve, and the water pump supplies water to the spray mechanism and the spray mechanism respectively through the electric three-way valve; the water pump is also connected to a variable frequency speed regulator, and the spray mechanism and the spray mechanism are both provided with a flow meter, which is electrically connected to the controller, and the flow meter is used to monitor the water flow velocity and flow rate in the pipeline of the spray or spray mechanism, and the analysis and judgment unit is also used to calculate the flow velocity of the automatic sprinkler system according to the wind speed, and send the flow velocity to the controller of the automatic sprinkler system, and the controller is used to control the variable frequency speed regulator to adjust the working frequency of the water pump according to the flow velocity.

[0039] Since the spray water sprayed at high speed is not easily blown away by the wind, the flow rate of the curing water can be controlled according to the wind speed to reduce the deviation effect of the wind speed on the curing water and improve the curing effect. At the same time, when the concrete strength does not meet the requirements of the spray water spraying, the spray flow rate of the spray mechanism can be increased to increase the spray volume, which can also further reduce the deviation effect of the wind speed on the curing water.

[0040] The data storage module is also used to store the maintenance time of the current tower column spraying section. The analysis and judgment module is also used to calculate the concrete predicted strength data based on the temperature data and the maintenance time, and judge whether the concrete predicted strength data is greater than the preset spraying intensity limit. If the judgment result is yes, then when it is judged that the wind speed is greater than the set wind speed, the mode switching unit controls the automatic water sprinkler system to work in the spray mode; if the judgment result is no, then when it is judged that the wind speed is greater than the set wind speed, the mode switching unit still controls the automatic water sprinkler system to work in the spray mode.

[0041] When the concrete strength does not meet the requirements, that is, it is less than the spray intensity limit, the water flow intensity of the spray mechanism is likely to damage the concrete surface, thereby affecting the surface structure of the tower column concrete. Therefore, at this time, the water output is adjusted through the flow meter and frequency converter, and the spray flow rate of the spray mechanism is increased to increase the spray volume, which can further reduce the deviation effect of wind speed on the curing water. When the strength of the concrete reaches or exceeds the required spray intensity limit, it indicates that the concrete has sufficient structural strength to resist the higher water flow pressure. At this time, you can choose whether to enable the spray mode according to the actual wind speed conditions. In the case of high wind speed, the spray mode is more suitable because the water droplets it produces are larger and not easily blown away by the wind, so it can more effectively keep the concrete surface moist.

[0042] It also includes a canyon wind field prediction module, a meteorological data acquisition module and a flow budget module. The meteorological data acquisition module is used to obtain meteorological data within a future set time period. The meteorological data includes wind speed and wind direction parameters. The canyon wind field prediction module uses a pre-trained prediction model and predicts the wind speed data at the tower column within a preset time period based on the meteorological data; the data monitoring module is also used to collect the water level data of the water tank of the automatic sprinkler system, and obtain the water volume of the water tank based on the current water tank water level data. The flow budget module calculates the total amount of spraying of the automatic sprinkler system within a preset time period based on the wind speed data, and determines whether water replenishment is needed based on the total amount of spraying and the water volume in the water tank. If the judgment result is yes, the automatic sprinkler system is controlled to replenish the water tank in advance.

[0043] The predicted wind speed can be used to determine the water consumption in the future preset time period, so as to achieve timely water replenishment in the water tank to prevent the automatic water sprinkler system from being insufficiently supplied with water, affecting the curing effect of the tower column concrete, and even causing cracks on the concrete surface, affecting the safety and durability of the structure. For example, if the preset time is the next 2 days, and it is predicted that the wind speed in the next 2 days will be high, high-flow spraying maintenance is required to prevent the concrete from being blown away by the wind and failing to meet the concrete curing requirements, resulting in a large water consumption in the next two days. The water tank is replenished in time with the water volume estimated in advance to ensure that there is enough water to supply the automatic water sprinkler system.

[0044] Example 2 Figure 2As shown, the automatic water spraying system includes a controller, an electric three-way valve, a water tank, a water pump, a spray mechanism and a spray mechanism, and an angle adjustment mechanism for adjusting the nozzle angle of the spray mechanism or the spray mechanism, wherein the controller, the electric three-way valve, the water tank, the water pump, are not shown in the figure, the spray mechanism and the spray mechanism are arranged in parallel and are located at different heights; the controller controls the water pump and the electric three-way valve to work, and the water pump supplies water to the spray mechanism and the spray mechanism respectively through the electric three-way valve; the angle adjustment mechanism includes a fixed bracket 2, a movable bracket 3, and a driving rod for driving the movable bracket 3, the driving rod adopts an electric telescopic rod, and the fixed bracket 2 It is detachably fixed to the tower column 1, one end of the driving rod is rotatably connected to the fixed bracket 2, and the other end is hinged to the movable bracket 3. The driving rod includes a horizontal telescopic rod 5 that drives the movable bracket 3 to move left and right, and a vertical telescopic rod that drives the movable bracket 3 to move up and down; a water pipe 4 is detachably fixed to the fixed bracket 2, the nozzle is connected to the water pipe 4 through a universal joint and the water outlet faces the surface of the tower column 1, the movable bracket 3 is provided with a slot, and the movable bracket 3 is located between the fixed bracket 2 and the tower column 1, and the nozzle passes through the slot and is movably connected to the movable bracket 3; an angle sensor is provided on the nozzle, and the angle sensor and the driving rod are electrically connected to the controller respectively. A retention groove 7 is provided at the lower end of the fixed bracket 2, and the retention groove 7 is tightly attached to the surface of the tower column 1 and is detachably fixed to the tower column 1. The retention groove 7 is used to collect the maintenance water sprayed from the upper construction section and the rust water that may be generated.

[0045] The angle adjustment mechanism uses four groups of fixed brackets 2, movable brackets 3, and driving rods to surround the tower column 1 on all sides. Each group is provided with a fixed bracket 2, a movable bracket 3, two transverse telescopic rods 5, and two vertical telescopic rods. The two transverse telescopic rods 5 are respectively arranged at the two ends of the movable bracket 3 along the transverse direction, and the two vertical telescopic rods are respectively arranged at the two ends of the movable bracket 3 along the vertical direction. The controller controls the transverse telescopic rod 5 and the vertical telescopic rod to adjust the position of the movable bracket 3, thereby adjusting the angle of the nozzle. For example, when only left and right offsets are required, the transverse telescopic rod 5 at one end is first controlled to shorten and the transverse telescopic rod 5 at the other end is extended. Since the movable bracket 3 is connected to the vertical telescopic rod at the same time, in order to meet the lateral movement, the vertical telescopic rod needs to be controlled to extend a certain distance at the same time, so that the movable bracket 3 can be translated to the set position, so that the rotation angle of the nozzle meets the set value. Through the cooperation of the movable bracket 3 and the transverse telescopic rod 5 and the vertical telescopic rod, the synchronous adjustment of the angles of multiple nozzles on the same side of the tower column 1 can be achieved, with high adjustment efficiency and simple equipment structure.

[0046] The analysis and control module also includes a degree adjustment unit. The angle adjustment unit is used to calculate the offset and offset angle of the water droplets from the nozzles of the current automatic sprinkler system to the tower column based on the predicted wind direction and wind speed data, and to calculate the adjustment direction and adjustment angle based on the offset and the offset angle. The automatic sprinkler system adjusts the sprinkler based on the adjustment direction and the adjustment angle.

[0047] For example, the calculated adjustment angle is α, which is the offset angle relative to the initial nozzle direction. If only the horizontal adjustment is considered to change the angle, for a rotating nozzle with a radius of r, r is the distance from the nozzle to its rotation center, the relationship between the horizontal movement and the angle can be expressed by trigonometric functions. Assuming that the nozzle rotates to the left as the positive angle direction, the horizontal movement Δx = rsinα. By controlling the distance Δx that the nozzle moves to the left or right in the horizontal direction, the initial adjustment of the angle can be achieved. Similarly, when only the distance in the up and down directions needs to be adjusted separately, the calculation method based on the same principle can be used.

[0048] When the obtained adjustment angle α needs to be adjusted in both horizontal and vertical directions, α is decomposed into the horizontal angle α' and the elevation angle β'. Assume that the current elevation angle of the nozzle is β; when the nozzle is adjusted up and down, the elevation angle value will change, which will indirectly affect the angle at which the water droplets reach the tower column. If the nozzle is moved upward by a distance Δy, the new nozzle elevation angle β' can be determined based on the structure of the nozzle and the water spray characteristics, which can be determined by the formula Δy is calculated, and by adjusting Δy, the elevation angle of the water spray can be changed, and combined with the horizontal adjustment Δx, the nozzle can reach the calculated ideal angle. The nozzle angle can be adjusted by moving the vertical telescopic rod and the horizontal telescopic rod by the distances of Δy and Δx respectively.

[0049] Secondly, when it is detected that the concrete strength does not meet the spraying intensity limit, the angle adjustment unit can be used to adjust the nozzle of the automatic water spraying system by adjusting the direction and angle, thereby preventing the mist droplets sprayed by the spray system from being too offset and unable to moisturize and cool the tower surface. In addition, even when the spray mode is enabled, the angle adjustment mechanism can be used to further optimize the spray angle of the nozzle to cope with the challenges brought by strong winds and ensure that the water can be evenly distributed on the surface of the tower, thereby achieving the best maintenance effect.

[0050] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
