Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology, and in particular to a portable dust suppression device. Background Technology

[0002] In the process of building construction, in order to effectively curb the spread of a large amount of dust during construction and reduce its potential harm to the surrounding environment and construction workers, it is particularly important to use dust suppression devices to spray atomized water. This process can not only significantly reduce the concentration of dust in the air, but also create a healthier and safer working environment for the construction area.

[0003] In the application of existing dust suppression devices, the nozzles used for atomization and spraying are mostly fixed in appropriate positions on the dust suppression device by a threaded locking mechanism. Since the nozzles are consumables, they often need to be disassembled regularly for cleaning or replacement after a period of use. However, the traditional threaded locking method has brought inconvenience to the disassembly and assembly of the nozzles to a certain extent, making the maintenance process of the dust suppression device time-consuming. Summary of the Invention

[0004] This disclosure relates to a portable dust suppression device, which consists of a mounting base, support legs, sliding parts, and expansion linkages forming a folding structure. This folding structure allows the dust suppression device to be stably erected at the construction site, and its folding feature can lock the volume when not in use, making it convenient to carry or store.

[0005] In a first aspect, this disclosure provides a portable dust suppression device, specifically comprising: a mounting base, wherein a mounting plate is fixedly mounted on the outer circumferential wall of the mounting base; a support leg is rotatably mounted on the outer end of the mounting plate; a connector is fixedly mounted on the outer circumferential wall of the support leg; a connecting pipe is fixedly mounted on the bottom end of the mounting base; a threaded joint is fixedly connected to the bottom end of the connecting pipe; the connecting pipe is connected to an external water supply pipe via the threaded joint; a sliding element is slidably mounted on the connecting pipe; a spreading connecting rod is rotatably mounted on the outer wall of the sliding element; and the other end of the spreading connecting rod is rotatably connected to the connector. The mounting base is connected to the following components: a limiting post is slidably installed inside the mounting base; the outer end of the limiting post is hemispherical; a baffle is fixedly installed on the outer circumference of the limiting post; the baffle is disc-shaped; a spring is embedded between the outer side of the baffle and the interior of the mounting base; a connector is inserted at the center of the interior of the mounting base; a limiting hole is formed on the outer circumference of the connector; a dust suppression nozzle is fixedly connected to the top of the connector; a loading groove is formed at the bottom of the interior of the mounting base; a control torsion ring is rotatably installed inside the loading groove; the control torsion ring is an annular structure.

[0006] In at least some embodiments,

[0007] The control torsion ring is also rotatably connected to the outer wall of the mounting base; a transmission groove is provided on the inner circumference of the control torsion ring.

[0008] In at least some embodiments,

[0009] The interior of the transmission groove has an arc-shaped structure; a torsion spring is installed between the bottom of the control torsion ring and the interior of the loading groove.

[0010] In at least some embodiments,

[0011] When the connector is inserted into the mounting base, the inner end of the connector will be inserted into the limiting hole.

[0012] In at least some embodiments,

[0013] The hemispherical structure at the outer end of the limiting insert is also inside the transmission groove and in contact with the arc-shaped surface of the transmission groove.

[0014] In at least some embodiments,

[0015] When the control torsion ring rotates counterclockwise, the arc-shaped surface of the transmission groove will gradually cancel the pushing action on the limiting insert hemispherical structure.

[0016] In at least some embodiments,

[0017] After the arc-shaped surface of the transmission groove cancels the pushing and limiting of the limiting pin, the inner end of the limiting pin will disengage from the inside of the limiting hole.

[0018] This utility model provides a portable dust suppression device, which has the following beneficial effects:

[0019] 1. This dust suppression device is equipped with a control torsion ring. By simply rotating this torsion ring, the limiting pin can be smoothly disengaged from the limiting hole under the coordinated action of related structures, thereby releasing the positional constraints on the connector and dust suppression nozzle. This design greatly simplifies the replacement process of the dust suppression nozzle. Compared with the traditional threaded locking method, this device is more convenient and faster to install and remove the dust suppression nozzle, which not only improves the efficiency of maintenance work, but also further ensures the convenience of the maintenance process.

[0020] II. Through the design of the mounting base, support legs, sliding parts, and expansion linkages, a sturdy yet flexible folding structure is constructed. This structure not only allows the dust suppression device to be stably erected on the construction site, ensuring its stable operation, but also, thanks to its unique folding function, can significantly reduce the size of the device when not in use, thereby greatly facilitating the carrying and storage of the dust suppression device.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Please refer to Figures 1 to 6 :

[0034] Example 1:

[0035] This utility model discloses a portable dust suppression device, comprising: a mounting base 1, a mounting plate 2 fixedly mounted on the outer circumference of the mounting base 1; a support leg 3 rotatably mounted on the outer end of the mounting plate 2; a connector 4 fixedly mounted on the outer circumference of the support leg 3; a connecting pipe 5 fixedly mounted on the bottom end of the mounting base 1; a threaded joint fixedly connected to the bottom end of the connecting pipe 5; the connecting pipe 5 is connected to an external water supply pipe through the threaded joint; a sliding component 6 is slidably mounted on the connecting pipe 5; a spreading connecting rod 7 is rotatably mounted on the outer wall of the sliding component 6; the other end of the spreading connecting rod 7 is rotatably connected to the connector 4; a limiting post 8 is slidably mounted inside the mounting base 1; the outer end of the limiting post 8 has a hemispherical structure; a baffle 9 is fixedly mounted on the outer circumference of the limiting post 8; the baffle 9 has a disc-shaped structure; a spring 10 is embedded between the outer side of the baffle 9 and the interior of the mounting base 1; and a spring 10 is inserted at the center of the interior of the mounting base 1. The device is equipped with a connector 11; a limiting hole 12 is opened on the outer circumference of the connector 11; a dust suppression nozzle 13 is fixedly connected to the top of the connector 11; a loading groove 14 is opened at the bottom of the inner side of the mounting base 1; a control torsion ring 15 is rotatably installed inside the loading groove 14; the control torsion ring 15 is a circular structure. When the dust suppression device needs to be erected on the construction site, the sliding member 6 is slid down along the connecting pipe 5 by hand, so that the sliding member 6 moves down with one end of the expansion rod 7, and the other end of the expansion rod 7 starts to push the connecting member 4 and the support leg 3 outward due to the downward effect, so that the support leg 3 is rotated by force to open up, so that the dust suppression device can be stably erected on the construction site through the opened support leg 3. Then, it is connected to the external water supply pipe through the threaded structure on the connecting pipe 5, and then water is supplied. The supplied water is atomized through the dust suppression nozzle 13 and discharged to complete the dust suppression work on the construction site.

[0036] In Example 2, based on Example 1, the control torsion ring 15 is also rotatably connected to the outer wall of the mounting base 1; a transmission groove 16 is provided on the inner circumference of the control torsion ring 15; the interior of the transmission groove 16 has an arc-shaped structure; a torsion spring 17 is installed between the bottom of the control torsion ring 15 and the interior of the loading groove 14; when the plug 11 is inserted into the interior of the mounting base 1, the inner end of the plug 11 will be inserted into the interior of the limiting hole 12. When the dust suppression device is not in use, the sliding member 6 is manually slid up, causing it to rise with one end of the expansion connecting rod 7, so that the other end of the expansion connecting rod 7 is subjected to a pulling force and the pulling force is transmitted to the connecting member 4 and the support leg rod 3, so that the support leg rod 3 is pulled and folded up, effectively reducing the volume of the dust suppression device and making it easier to carry and transfer the dust suppression device.

[0037] In Example 3, based on Example 2, the hemispherical structure at the outer end of the limiting pin 8 is still inside the transmission groove 16 and in contact with the arc surface of the transmission groove 16. When the control ring 15 is rotated counterclockwise, the arc surface of the transmission groove 16 will gradually release the pushing force on the hemispherical structure of the limiting pin 8. After the arc surface of the transmission groove 16 releases the pushing force on the limiting pin 8, the inner end of the limiting pin 8 will disengage from the inside of the limiting hole 12. When it is necessary to disassemble the dust suppression nozzle 13, it is only necessary to rotate the control ring 15 counterclockwise to make it rotate with the transmission groove 16, so that the arc surface of the transmission groove 16 will gradually release the pushing force on the hemispherical structure of the limiting pin 8, thereby causing the limiting pin 8 to move outward under the action of the spring 10, and causing the inner end of the limiting pin 8 to disengage from the inside of the limiting hole 12, thereby releasing the limiting force on the dust suppression nozzle 13, which facilitates the disassembly and maintenance of the dust suppression nozzle 13.

[0038] The working principle of this embodiment:

[0039] When the dust suppression device needs to be installed on the construction site, the sliding member 6 is manually slid down along the connecting pipe 5, causing the sliding member 6 to move downwards along with one end of the expansion rod 7. The other end of the expansion rod 7, affected by the downward movement, pushes outwards against the connecting member 4 and the support leg 3, causing the support leg 3 to rotate and open. This allows the dust suppression device to be stably installed on the construction site. Then, the threaded structure on the connecting pipe 5 is used to connect to an external water supply pipe, and water is supplied. The supplied water is atomized through the dust suppression nozzle 13 and discharged, completing the dust suppression work on the construction site. When the dust suppression device is not in use, the sliding member 6 is manually slid up, causing the expansion rod 7 to move downwards along with the support leg 7. One end of the connecting rod 7 rises, causing the other end of the expanding connecting rod 7 to be subjected to a pulling force, which is then transmitted to the connecting piece 4 and the support leg rod 3. This causes the support leg rod 3 to be pulled and folded up, effectively reducing the volume of the dust suppression device and making it easier to carry and transfer the dust suppression device. When it is necessary to disassemble the dust suppression nozzle 13, simply rotate the control ring 15 counterclockwise to make it rotate with the transmission groove 16. This causes the arc surface of the transmission groove 16 to gradually release the pushing force on the hemispherical structure of the limiting pin 8, thereby causing the limiting pin 8 to move outward under the action of the spring 10. This causes the inner end of the limiting pin 8 to disengage from the inside of the limiting hole 12, thereby releasing the limitation on the dust suppression nozzle 13 and making it easier to disassemble and maintain the dust suppression nozzle 13.
