Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically a dust suppression device for green construction. Background Technology

[0002] A large amount of dust generated during construction will be suspended in the air, increasing the content of pollutants such as inhalable particulate matter in the air. Dust reduction measures can effectively reduce dust emissions, lower the level of air pollution, and improve the air quality in and around the construction area.

[0003] Existing dust suppression devices mainly involve mounting a fog cannon onto a vehicle. The movement of the vehicle, combined with the rotation of the fog cannon, is used to suppress dust at the construction site. The pitch and rotation of the fog cannon are controlled by the extension and retraction of a hydraulic cylinder. However, since one end of the hydraulic cylinder is located on the base of the fog cannon and the other end is located below it, this structure has significant limitations on the pitch angle. As a result, in some special construction scenarios, such as dust suppression operations on the top of tall buildings or at the bottom of deep foundation pits, it is impossible to accurately cover the target area with water mist, significantly reducing the dust suppression effect and failing to meet the dust suppression needs of complex and ever-changing construction environments.

[0004] Therefore, it is necessary to design a dust suppression device for construction with a large pitch angle. Utility Model Content

[0005] The purpose of this invention is to provide a dust suppression device for green construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for green construction, comprising a turntable, wherein the turntable is rotatably mounted on a base, and the base is used to fix it on a carrier;

[0007] A bracket is fixed on the turntable to accommodate the tail of the fog cannon. One end of a driven short connecting rod is rotatably mounted at the front of the bracket, and the other end of the driven short connecting rod is rotatably mounted at the tail of the fog cannon.

[0008] The fog cannon has a long connecting rod at one end that rotates in the middle, an auxiliary short connecting rod at one end that rotates in the middle of the long connecting rod, and the other end of the auxiliary short connecting rod that rotates on the bracket.

[0009] One end of the middle long connecting rod is rotatably connected to one end of the active long connecting rod, and the other end of the active long connecting rod is rotatably located at the rear of the bracket.

[0010] The active long linkage is driven by a pitch actuator, which is mounted on a turntable and electrically connected to the control module.

[0011] Preferably, a hinge seat is fixed on the active long connecting rod, and the pitch actuator includes a servo hydraulic cylinder, one end of which is rotatably mounted on the turntable, and the other end is rotatably mounted on the hinge seat.

[0012] Preferably, the servo hydraulic cylinder pipeline is connected to the servo valve, and the servo valve is electrically connected to the control module.

[0013] Preferably, the servo valve pipeline is connected to the hydraulic station, which is fixed inside the base.

[0014] Preferably, the control module is fixed inside the base, and the control module is a 32-bit microcontroller.

[0015] Preferably, an external gear ring is fixed under the turntable, and the external gear ring is meshed with a drive gear, which is mounted on the base for rotation.

[0016] Preferably, the drive gear is driven by a servo motor, which is fixed inside the base.

[0017] Preferably, the servo motor is electrically connected to the control module.

[0018] Preferably, a reinforcing rib is fixed on the active long connecting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the pitch actuator drives the active long connecting rod to rotate, which in turn drives the intermediate long connecting rod to move, which in turn drives the auxiliary short connecting rod to rotate. The movement of the intermediate long connecting rod can drive the fog cannon to move, which in turn drives the driven short connecting rod to rotate. By setting the intermediate long connecting rod on the active long connecting rod and the auxiliary short connecting rod, the movement of the intermediate long connecting rod is controlled. By setting the fog cannon on the intermediate long connecting rod and the driven short connecting rod, the pitch range of the fog cannon is expanded, making it easier to cover the construction area on the top of higher buildings or the bottom of deeper foundation pits with water mist, thus meeting the dust suppression needs of complex and ever-changing construction environments.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: a dust suppression device for green construction, such as... Figure 1 As shown, it includes a turntable 1, which is rotatably mounted on a base 2, which is used to fix it to a carrier.

[0026] like Figure 1 , 3 As shown, a bracket 3 is fixed on the turntable 1. The bracket 3 is used to accommodate the tail of the fog cannon 4. One end of the driven short connecting rod 5 is rotatably arranged in front of the bracket 3, and the other end of the driven short connecting rod 5 is rotatably arranged in the tail of the fog cannon 4.

[0027] like Figure 1 , 3 As shown, one end of the middle long connecting rod 6 is rotatably mounted in the middle of the fog cannon 4, and one end of the middle long connecting rod 6 is rotatably mounted in the middle of the middle, with the length of the auxiliary short connecting rod 7 being shorter than the length of the middle long connecting rod 6. The other end of the auxiliary short connecting rod 7 is rotatably mounted on the bracket 3.

[0028] like Figure 1 , 3 As shown, one end of the active long connecting rod 8 is rotatably mounted on the other end of the middle long connecting rod 6. The other end of the active long connecting rod 8 is rotatably mounted behind the bracket 3. The length of the active long connecting rod 8 is longer than the length of the driven short connecting rod 5.

[0029] like Figure 1 , 2 As shown, the active long link 8 is driven by a pitch actuator, which is mounted on the turntable 1 and electrically connected to the control module.

[0030] When the fog cannon 4 sprays upwards, the pitch actuator drives the active long connecting rod 8 to rotate backwards, which in turn drives the middle long connecting rod 6 to move, which in turn drives the auxiliary short connecting rod 7 to rotate backwards. The movement of the middle long connecting rod 6 can drive the middle part of the fog cannon 4 to move upwards, which in turn drives the driven short connecting rod 5 to rotate backwards, which in turn drives the tail of the fog cannon 4 to move backwards, which in turn drives the head of the fog cannon 4 to tilt upwards.

[0031] When the fog cannon 4 sprays downwards, the pitch actuator drives the active long connecting rod 8 to rotate forward, which in turn drives the middle long connecting rod 6 to move, which in turn drives the auxiliary short connecting rod 7 to rotate forward. The movement of the middle long connecting rod 6 can drive the middle part of the fog cannon 4 to move downwards, which in turn drives the driven short connecting rod 5 to rotate forward, which in turn drives the tail of the fog cannon 4 to move forward, which in turn drives the head of the fog cannon 4 to tilt downwards.

[0032] By setting the intermediate long connecting rod 6 on the active long connecting rod 8 and the auxiliary short connecting rod 7, the movement of the intermediate long connecting rod 6 is controlled. By setting the fog cannon 4 on the intermediate long connecting rod 6 and the driven short connecting rod 5, the pitch range of the fog cannon 4 is expanded, which makes it easier to cover the construction area on the top of higher buildings or the bottom of deeper foundation pits with water mist, and to meet the dust suppression needs of complex and ever-changing construction environments.

[0033] like Figure 2 , 3 As shown, in order to facilitate the driving of the active long link 8, a hinge seat 9 is fixed on the active long link 8. The pitch actuator includes a servo hydraulic cylinder 10. One end of the servo hydraulic cylinder 10 is rotatably mounted on the turntable 1, and the other end is rotatably mounted on the hinge seat 9. The servo hydraulic cylinder 10 is connected to a servo valve through a pipeline. The servo valve is electrically connected to the control module. The servo valve is connected to a hydraulic station through a pipeline. The hydraulic station is fixed inside the base 2.

[0034] When the servo hydraulic cylinder 10 shortens, it can drive the hinge seat 9 to rotate, which in turn drives the active link 8 to rotate backward. When the servo hydraulic cylinder 10 extends, it can drive the hinge seat 9 to rotate, which in turn drives the active link 8 to rotate forward.

[0035] For ease of control, the control module is fixed inside the base 2. The control module is a 32-bit microcontroller.

[0036] To facilitate direction adjustment, an external gear ring 11 is fixed under the turntable 1. The external gear ring 11 is meshed with a drive gear 12. The drive gear 12 is rotatably mounted on the base 2. The drive gear 12 is driven by a servo motor, which is fixed inside the base 2 and electrically connected to the control module.

[0037] The servo motor can drive the drive gear 12 to rotate, which in turn drives the external gear ring 11 to rotate, which in turn drives the turntable 1 to rotate.

[0038] To improve the strength of the active long link 8, a reinforcing rib 13 is fixed on the active long link 8.

[0039] Working process: When the fog cannon 4 sprays upwards, the control module controls the servo valve to operate. The servo valve controls the servo hydraulic cylinder 10 to shorten, which in turn drives the active long connecting rod 8 to rotate backwards, which in turn drives the middle long connecting rod 6 to move, which in turn drives the auxiliary short connecting rod 7 to rotate backwards. The movement of the middle long connecting rod 6 can drive the middle part of the fog cannon 4 to move upwards, which in turn drives the driven short connecting rod 5 to rotate backwards, which in turn drives the tail of the fog cannon 4 to move backwards, which in turn drives the head of the fog cannon 4 to tilt upwards.

[0040] When the fog cannon 4 sprays downwards, the control module controls the servo valve to operate. The servo valve controls the servo hydraulic cylinder 10 to extend, which in turn drives the active long connecting rod 8 to rotate forward, which in turn drives the middle long connecting rod 6 to move, which in turn drives the auxiliary short connecting rod 7 to rotate forward. The movement of the middle long connecting rod 6 can drive the middle part of the fog cannon 4 to move downwards, which in turn drives the driven short connecting rod 5 to rotate forward, which in turn drives the tail of the fog cannon 4 to move forward, which in turn drives the head of the fog cannon 4 to tilt downwards.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
