Description

Technical Field

[0001] This utility model relates to the field of dust control, and in particular to a dust monitoring and automatic spraying device. Background Technology

[0002] Dust pollution specifically refers to the phenomenon where dust on the ground is lifted into the atmosphere by factors such as wind and human activities. Common human activities include building construction, road construction, material handling, and industrial production. The hazards of dust pollution include affecting air quality, reducing visibility, and damaging the environment.

[0003] Currently, considering the impact of dust, continuous sprinkler systems are often deployed at construction sites. While these systems effectively reduce dust, they consume significant amounts of water and electricity and cannot accurately determine dust concentration. To address this, some construction sites have added dust monitoring devices to monitor dust concentration in real time. However, the lack of a correlation between these monitoring devices and the sprinkler systems prevents timely spraying, resulting in unnecessary water and electricity consumption. Furthermore, existing sprinkler systems have limited coverage; when moved to a designated location, they can only spray dust within a certain area. Utility Model Content

[0004] The purpose of this invention is to provide a dust monitoring and automatic spraying device that can spray water and electricity in a timely manner according to dust concentration, has a large spraying range and can be appropriately adjusted.

[0005] The purpose of this utility model is achieved as follows: A dust monitoring and automatic sprinkler device includes several dust monitoring assemblies, each of which includes a dust monitoring sensor, a wireless communication device, and a mobile power supply; an automatic sprinkler device includes a water storage tank, a hollow central column disposed on the upper end of the water storage tank, a turntable rotatably mounted on the central column, a control box disposed on the side of the water storage tank, several sprinkler units disposed along the outer periphery of the turntable, and a turntable control mechanism disposed on the water storage tank for driving the turntable to reciprocate; the upper end of the central column is provided with several water inlets, each water inlet is provided with a solenoid valve, and the solenoid valves are respectively connected to the corresponding sprinkler units.

[0006] Furthermore, the above-mentioned spray unit includes a base, which is disposed on the outer periphery of the turntable; a first fixed seat, which is disposed on the base; and a spray rod, which is disposed on the first fixed seat, with a spray head at its outer end and a connecting hose connected to a corresponding solenoid valve at its inner end.

[0007] As a preferred embodiment of this utility model, the turntable is further provided with a limiting groove, the base is installed on the turntable and can slide along the outer periphery of the turntable; the cross section of the base is approximately C-shaped, the upper end of which is provided with a limiting screw that slides with the limiting groove, and the lower end of which is provided with a locking screw for locking and fixing the position of the base.

[0008] As a preferred embodiment of this utility model, the spray rod is hinged to the first fixed seat; the spray unit further includes an angle adjustment mechanism for controlling the spray angle of the spray rod; the angle adjustment mechanism includes a worm gear, which is disposed outside the first fixed seat and coaxially fixedly connected to the hinge end of the spray rod; a second fixed seat, which is disposed on the base; a worm, which is rotatably mounted on the second fixed seat and meshes with the worm gear; and a handwheel is provided at the outer end of the worm.

[0009] Furthermore, the aforementioned turntable control mechanism includes a gear disposed below the turntable and fixedly connected to the turntable coaxially, a rack meshing with the gear and capable of linear reciprocating movement, and a reciprocating drive mechanism disposed on the water storage tank for driving the rack to reciprocate linearly.

[0010] As a preferred embodiment of this utility model, the reciprocating drive mechanism includes a third fixed base, which is disposed on a water storage tank; a slide rod is provided on the third fixed base; a reciprocating lead screw, which is rotatably mounted on the third fixed base; a slider, which is disposed on the reciprocating lead screw and can move linearly back and forth along the reciprocating lead screw, one end of which is fixedly connected to a rack and the other end is slidably engaged with the slide rod; and a reciprocating motor, which is disposed on the third fixed base and is drivenly connected to the reciprocating lead screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model adds a dust monitoring assembly, which can monitor the dust concentration at the construction site in real time and feed the data back to the control box of the automatic sprinkler assembly. The control box opens the corresponding sprinkler unit in a timely manner according to the dust concentration, and sprays the dust to reduce the dust in the areas where the dust concentration exceeds the standard, thereby realizing timely spraying in combination with dust concentration to save water and electricity.

[0013] The automatic sprinkler assembly of this utility model includes multiple sprinkler units, which can simultaneously spray and reduce dust in multiple locations. The sprinkler units can move accordingly as the turntable reciprocates, further expanding the spray range, thus providing a large spray range. In addition, the angle position of the sprinkler rod of the sprinkler unit can be adjusted. As the angle position changes, the spray trajectory of the sprinkler water also changes accordingly, thereby changing the spray range and expanding the applicable range. Attached Figure Description

[0019] The following will refer to the appendices in the embodiments of the present invention. Figure 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, in conjunction with Appendix Figure 1-4 As shown, a dust monitoring and automatic sprinkler system includes several dust monitoring assemblies, each of which includes a dust monitoring sensor, a wireless communication device, and a power supply; the automatic sprinkler system includes a water tank 1, a hollow central column 2 disposed on the upper end of the water tank 1, a turntable 3 rotatably mounted on the central column 2, a control box 4 disposed on the side of the water tank 1, several sprinkler units 5 disposed along the outer periphery of the turntable 3, and a turntable control mechanism disposed on the water tank 1 for driving the turntable 3 to reciprocate; the upper end of the central column 2 is provided with several water inlets 2a, each water inlet 2a is provided with a solenoid valve 2b, and the solenoid valve 2b is respectively connected to the corresponding sprinkler unit 5;

[0021] It should be noted that the aforementioned portable power supply is electrically connected to the dust monitoring sensor and the wireless power supply device, respectively. It is preferable to use a portable power supply with a solar charging system. This design facilitates the selection of monitoring points and reduces the trouble of wiring.

[0022] The aforementioned central column 2 is also provided with several wire-passing holes 2c. The upper port of the wire-passing hole 2c is located at the upper end of the central column 2, and the lower port is located below the hinge section of the central column 2. This design facilitates the wiring of the solenoid valve 2b.

[0023] The water storage tank 1 is equipped with a water pump, and the outlet of the water pump is connected to the inner cavity of the central column 2. The spray water pumped out by the water pump first enters the inner cavity of the central column 2, and then flows out from the water supply port 2a, and is delivered to each spray unit 5 through the solenoid valve 2b and the connecting hose 7b.

[0024] The control box 4 is equipped with a main unit and a wireless communication device. The main unit is electrically connected to the water pump, the reciprocating motor 16, and the solenoid valve 2b, respectively. The dust monitoring sensor is connected to the main unit via the wireless communication device.

[0025] The above-mentioned spray unit includes a base 6, which is disposed on the outer periphery of the turntable 3; a first fixed seat 5c, which is disposed on the base 6; and a spray rod 7, which is disposed on the first fixed seat 5c, with a spray head 7a at its outer end and a connecting hose 7b at its inner end that is connected to the corresponding solenoid valve 2b.

[0026] It should be noted that the aforementioned connecting hose 7b should be used with sufficient slack so that it can deform as the spray unit 5 moves.

[0027] The aforementioned turntable control mechanism includes a gear 11 disposed below the turntable 3 and coaxially fixedly connected to the turntable 3; a rack 12 meshing with the gear 11 and capable of linear reciprocating movement; and a reciprocating drive mechanism disposed on the water storage tank 1 for driving the rack 12 to reciprocate linearly. The reciprocating drive mechanism includes a third fixed base 13 disposed on the water storage tank 1; a slide rod 13a disposed on the third fixed base 13; a reciprocating lead screw 14 rotatably mounted on the third fixed base 13; a slider 15 disposed on the reciprocating lead screw 14 and capable of linear reciprocating along the reciprocating lead screw 14, one end of which is fixedly connected to the rack 12, and the other end slidingly engaged with the slide rod 13a; and a reciprocating motor 16 disposed on the third fixed base 13 and connected to the reciprocating lead screw 14 in a transmission connection.

[0028] It should be noted that when the turntable control mechanism is working, the reciprocating motor 16 starts, which drives the reciprocating lead screw 14 to rotate. The slider 15 moves back and forth linearly under the action of the reciprocating lead screw 14 and the slide bar 13a, which in turn drives the rack 12 to move back and forth linearly, and drives the turntable 3 to rotate back and forth through the gear 11, ultimately realizing the reciprocating rotation of the spray unit 5.

[0029] When using,

[0030] First, several dust monitoring assemblies are installed at each monitoring point;

[0031] Next, place the automatic sprinkler assembly in a suitable position to ensure that the spray range of the sprinkler unit 5 can cover the designated area;

[0032] Finally, connect the power supply and start the dust monitoring assembly and automatic spray assembly. The dust monitoring sensor transmits the monitored dust concentration data to the host via wireless communication equipment. When the host determines that the dust concentration in a certain area exceeds the standard, it starts the reciprocating motor 16 and the water pump, and opens the corresponding solenoid valve 2b, so that the corresponding spray unit 5 is connected to the water source to spray and reduce dust in the area where the dust concentration exceeds the standard. The start of the reciprocating motor 16 drives the turntable 3 to rotate back and forth, which in turn drives the spray unit 5 to rotate back and forth, further expanding the spray range and ensuring sufficient dust reduction until the dust concentration in the area meets the standard.

[0033] Example 2, in conjunction with Appendix Figure 1-3 As shown, Embodiment 2 is similar to Embodiment 1, except that the turntable 3 is further provided with a limiting groove 3a, and the base 6 is installed on the turntable 3 and can slide along the outer periphery of the turntable 3; the cross-section of the base 6 is approximately C-shaped, with a limiting screw 6a at the upper end that slides with the limiting groove 3a, and a locking screw 6b at the lower end for locking and fixing the position of the base 6; this design makes the relative position of the spray unit 5 and the turntable 3 adjustable, thereby enabling the automatic spray device to simultaneously cover multiple monitoring areas in different directions, thus facilitating flexible on-site adjustments and expanding the scope of application;

[0034] It should be noted that when adjusting the position of the spray unit 5, first loosen the locking screw 6b to ensure that the spray unit 5 can slide; then slide the spray unit 5 to the appropriate position along the turntable 3; finally, tighten the locking screw 6b to fix the position of the spray unit 5.

[0035] Example 3, in conjunction with Appendix Figure 1-3As shown, Embodiment 3 is similar to Embodiments 1 and 2, except that the spray rod 7 is hinged to the first fixed base 6c; the spray unit 5 also includes an angle adjustment mechanism for controlling the spray angle of the spray rod 7; the angle adjustment mechanism includes a worm gear 8, which is disposed outside the first fixed base 6c and coaxially fixedly connected to the hinge end of the spray rod 7; a second fixed base 9, which is disposed on the base 6; a worm 10, which is rotatably mounted on the second fixed base 9 and meshes with the worm gear 8; and a handwheel 10a is provided at the outer end of the worm 10. This design makes the vertical spray angle adjustable. Under the premise that the water pump supply pressure remains unchanged, as the vertical spray angle changes, the spray trajectory changes accordingly, and the spray range also changes accordingly, thereby enabling the spray range to overlap with the monitoring area more, so as to obtain a better dust suppression effect.

[0036] It should be noted that when adjusting the vertical spray angle, turning the handwheel 10a drives the worm gear 10 to rotate. As the worm gear 10 rotates, the worm wheel 8 rotates accordingly, which in turn drives the spray bar 7 to rotate vertically to the appropriate angle.

[0037] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In this invention, it should also be noted that the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integrally formed connection, a mechanical connection, or an indirect connection through intermediate connecting parts. The specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.
