DETAILED DESCRIPTION

[0048] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0049] Embodiment 1

[0050] like Figure 1-3 As shown, the present invention provides a sprinkler system attached to a street light pole, comprising:

[0051] A detector 1, which is arranged on a street light pole 3 and is used to detect a gas state. The detector 1 includes but is not limited to an atmosphere monitoring device and a PM detector;

[0052] A spraying part 2, wherein the spraying part 2 is arranged on the street light pole 3 and is used for irrigation;

[0053] A control system, wherein the control system is electrically connected to the detector 1 and the spray part 2, and the control system is used to drive the spray part 2 to irrigate and remove dust after receiving the state of the detector 1;

[0054] The control system includes a data acquisition module, a central processing unit, a data analysis module, a sending module and an execution module, wherein:

[0055] The acquisition module is used to acquire the air state monitored by the detector 1, and send the air state to the central processor through the sending module. The central processor is used to process the air state data to obtain air pollution degree information, and send the gas pollution degree information to the data analysis module through the sending module. The data analysis module is used to analyze whether the air pollution degree information reaches a threshold value;

[0056] If the threshold is reached, the data analysis module sends a start instruction to the execution module, and the execution module drives the spraying part 2 to irrigate and remove dust. Specifically, in the prior art, watering and dust reduction work is carried out by a sprinkler truck. During the driving process of the sprinkler truck, due to factors such as vehicle speed and water volume control, it is often impossible to achieve accurate dust reduction, resulting in low equipment efficiency. The purchase, maintenance and operation costs of the sprinkler truck are high, which brings great economic pressure to urban managers. When the sprinkler truck is driving on the road, it is easy to cause traffic jams and aggravate urban traffic pressure. In view of the above problems, the existing resources in urban road construction are in urgent need of more effective utilization. Usually, street lights, green belts and irrigation systems are set up beside urban roads. If these resources can be effectively integrated, especially the greening spray device is effectively connected with the street light, it will significantly improve the microclimate beside the road, and play a multiple role in purifying the air and maintaining greening. Such an innovative design is not only expected to solve the heat island effect and air pollution problems, but also to improve the utilization efficiency of urban infrastructure and create a more livable living environment for urban residents. The present invention uses a detector 1 to monitor the dust status in the air in real time, and obtains it through a data acquisition module, processes it through a central processing unit, analyzes it through a data analysis module, sends it through a sending module, and executes it through an execution module, so that the spray part 2 is intelligently triggered, and sprays dust multiple times or in a targeted manner according to the dust status in real time, and its operation can only be intelligently triggered when the dust amount exceeds the threshold. The water mist sprayed by the spray part 2 adheres to the dust, and it falls together with the load. The dust-carrying water mist can also act on the plants in the green belt, thereby improving efficiency, reducing waste, and protecting the respiratory health and vision of passers-by; and this product is attached to the street light pole 3, and can be quickly set up and modified, playing a variety of protective and Cleaning effect. According to the construction logic of the street light pole 3 being close to the green belt, the spray part 2 on the street light pole 3 can also act on the green belt. While reducing dust, it can replenish water and clean the green belt, so that irrigation work and dust reduction work can be well coordinated. By combining the street light pole 3 with the spray device and installing an intelligent monitoring and control system, the problem of the existing technology of separately carrying out road watering or greening maintenance can be solved, and the automatic spraying maintenance function can be achieved, the use of sprinkler trucks can be reduced, traffic pressure can be alleviated, and air quality can be improved. The application of the intelligent monitoring and control system solves the problem that traditional road watering and greening maintenance usually rely on manual operation, which is inefficient and difficult to achieve precise control. By integrating the street light pole and the spray device, the device not only has the lighting function, but can also carry out road watering and greening maintenance, realizing the multifunctionality of a single facility.

[0057] Optionally, the data acquisition module is used to obtain dust concentration information and record the time the concentration information value exists, wherein the calculation formula is:

[0058] D = V / K × 10S;

[0059] D is the concentration, V is the voltage, K is the sensitivity coefficient of the sensor, and 10S is the duration. Specifically,

[0060] D is the concentration of dust in the detection environment, and V is the voltage value converted from the electrical signal generated by the sensor during the dust detection process. This voltage value has a certain correspondence with the existence and concentration of dust, and is a characteristic parameter of the sensor. It reflects the sensitivity of the sensor to changes in dust concentration. It corresponds to detector 1, and 10 seconds is the duration of existence. This formula can be applied to dust monitoring equipment. By measuring the voltage value output by the sensor and combining it with the known sensitivity coefficient, the dust concentration in the environment is calculated. When the dust concentration exists for 10 seconds, the related equipment is triggered to work, avoiding short-term environmental pollution and allowing the spray part 2 to work. The short-term dust concentration state can be freely contacted, saving the use of water resources.

[0061] Optionally, the data acquisition module is further used to obtain the volume range of dust in the air, and determine whether it is less than a preset value according to the volume range;

[0062] If the volume range is less than the preset value, it is determined that the air pollution level is within the controllable range;

[0063] If the volume range is greater than the preset value, it is determined that the air pollution level exceeds the limit value, and the gas pollution level information is sent to the data analysis module through the sending module according to the central processor, and the data analysis module sends a start instruction to the execution module, and the execution module drives the spray part 2 to irrigate and remove dust. Specifically, the dust concentration range determines the pollution range. When the dust concentration range is small, it can be quickly diluted or dispersed by itself, and its state is released in a short time. There is no need to intervene through intervention measures, which also protects the waste of water resources to another extent. When the dust concentration range is large, when the free dispersion speed and efficiency are too slow, the spray part 2 can intervene in time and effectively.

[0064] Optionally, the execution module includes:

[0065] An execution unit, the execution unit is used to control the opening and closing of the spray part 2;

[0066] A pressurizing unit, the pressurizing unit is used to control the spraying part 2 to increase the water pressure;

[0067] The distance adjusting unit is used to adjust the irrigation range of the spraying part 2. Specifically, the spraying part 2 based on the execution unit can work effectively, the pressurizing unit can control the water pressure, and the distance adjusting unit can adjust the spraying distance, thereby completing the control of the spraying work.

[0068] Further, a remote terminal is included;

[0069] The data analysis module sends the gas pollution status to the remote terminal through the sending module;

[0070] After the gas pollution status is displayed on the remote terminal, the central processor can control the opening and closing of the spray part 2. Specifically, the remote terminal can be connected in an electrical or wireless network manner to receive background instructions. The remote terminal is a mobile phone or a computer, which can manually intervene in the spray part 2. When the intelligent dust reduction fails or the intelligent dust reduction effect is poor, timely remedial and emergency treatment can be carried out.

[0071] Embodiment 2

[0072] like Figure 4-6 As shown, two spray parts 2 are symmetrically staggered and arranged at different heights, and two through holes 7 are arranged on the left and right sides of the street light pole 3;

[0073] The spray part 2 includes a fixed tube 21 passing through the through hole 7, and two arc-shaped clamping plates 22 embedded in the fixed tube 21, wherein the inner wall of one of the arc-shaped clamping plates 22 is in contact with the outer side of the street light pole 3, and the outer side of the other arc-shaped clamping plate 22 is in contact with the inner side of the street light pole 3;

[0074] The distance between the two arc-shaped clamping plates 22 is equal to the wall thickness of the street light pole 3, and the height of the arc-shaped clamping plates 22 is greater than the height of the through hole 7, wherein:

[0075] The two arc-shaped clamping plates 22 are used to drive the fixed tube 21 to rise and fall along the street light pole 3. Specifically, the center of the arc-shaped clamping plates 22 coincides with the center of the street light pole 3. The spray part 2 at a lower height faces the green belt, mainly for irrigation, and the spray part 2 at a higher height faces the road surface, mainly for dust reduction. In one state, the street light pole 3 is pre-set not to consider facing the green belt or facing away from the green belt. The opening state of the through hole 7 can be adjusted according to actual application conditions. The combination of the two arc-shaped clamping plates 22 and the fixed tube 21 allows it to fine-tune the upper and lower distances and the rotation angles in the through hole 7, so that the fixed tube 21 can adapt to the angle and height of subsequent irrigation or dust reduction work.

[0076] Optionally, two hand-tightening bolts 4 are spirally connected to one of the arc-shaped clamping plates 22, wherein:

[0077] The two hand-tightening bolts 4 are used to position the height of the fixing tube 21 after spiral tightening. Specifically, the two hand-tightening bolts 4 are away from the through hole 7. When the height of the fixing tube 21 is adjusted with the arc-shaped clamping plate 22, the hand-tightening bolts 4 can be rotated to make their head ends contact the outer avoidance surface of the street light pole 3 to obtain a tightening effect for adjusting the height of the through hole 7. This operation method is fast and efficient, and the position setting of the two hand-tightening bolts 4 makes their tightening force more balanced.

[0078] Optionally, the spraying part 2 further includes a rotating tube 23 rotatably connected to the fixed tube 21, and two electronic spray heads 24 mirror-connected to the upper and lower ends of the rotating tube 23;

[0079] The electronic spray head 24 is electrically connected to the execution module. Specifically, the electronic spray head 24 has the function of rotating spraying, and two upper and lower electronic spray heads are arranged on the rotating tube 23. Normally, only one electronic spray head 24 is working and the other is spare. When one of the electronic spray heads 24 is damaged, the two electronic spray heads 24 can be replaced by rotating the rotating tube 23 one hundred and eighty degrees to achieve efficient emergency maintenance work efficiency. The electronic spray head 24 receives the signal of the execution module and works.

[0080] Optionally, the spray part 2 further includes a fixed ring 25 arranged on the rotating tube 23, a plurality of circular grooves 26 circumferentially arranged at one end of the fixed ring 25, two flat cutouts 27 arranged on the outer walls of the upper and lower ends of the fixed tube 21, a movable ring 28 that fits the two flat cutouts 27 and is sleeved on the outer wall of the fixed tube 21, and a plurality of frustum columns 29 circumferentially arranged at one end of the movable ring 28;

[0081] The plurality of truncated cone columns 29 are elastic, and the plurality of truncated cone columns 29 correspond to the plurality of circular grooves 26 one by one, wherein:

[0082] The movable ring 28 can drive the plurality of the frustum columns 29 to move along the fixed tube 21, so that the plurality of the frustum columns 29 can be inserted into the plurality of the circular grooves 26 to fasten the rotating tube 23 and the fixed tube 21. Specifically, the electronic spray head 24 cannot be fixed after the angle is adjusted with the rotating tube 23. The two flat cutouts 27 can prevent the movable ring 28 from rotating and allow it to move radially along the fixed tube 21. During the radial movement of the movable ring 28, the plurality of frustum columns 29 are driven to be inserted toward the plurality of circular grooves 26. The insertion resistance of the plurality of frustum columns 29 gradually increases until the plurality of frustum columns 29 are clearance-fitted or interference-fitted with the plurality of circular grooves 26. The electronic spray head 24 is also locked after the angle of the rotating tube 23 is adjusted, thereby ensuring the stability of the electronic spray head 24 after switching to work.

[0083] Optionally, one end of the fixed pipe 21 is connected to a water injection pipe 5 through a flexible water pipe, and one end of the water injection pipe 5 passes through the ground and is connected to a water extractor 6 or a water source;

[0084] The water injection pipe 5 is provided with a valve. Specifically, the flexible water pipe ensures that the height and angle adjustment of the fixed pipe 21 is not disturbed. The water extractor 6 can extract water on site by cooperating with an externally-dispatched water source after the water source is cut off. The water extractor 6 includes a vertical pipe, a bracket connected to the vertical pipe by a clamp or a cable tie, and a water intake head threadedly connected to the vertical pipe. It is quick to disassemble and assemble, portable and practical.
