Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a dust suppression device for building foundation pit spraying. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plan dimensions. Before excavation, an excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be carried out. During the excavation of the excavation pit, a large amount of dust will be generated. To avoid the impact of dust on the environment, dust suppression equipment needs to be used.

[0003] In existing technologies, the atomizing nozzles of spray dust suppression equipment are all fixed, which limits the range of dust suppression that can be achieved. Some areas still cannot be treated with atomized dust suppression, resulting in poor dust suppression effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the atomizing nozzles of existing dust suppression spraying equipment are all fixed, thus limiting the range of dust suppression and leaving some areas unable to be treated by atomization, resulting in poor dust suppression effect. Therefore, this invention proposes a dust suppression spraying device for building foundation pits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust suppression spraying device for building foundation pits, comprising a first limiting frame and a second limiting frame. Mounting seats are fixedly connected to the upper and lower parts of one end of the first limiting frame. Adjacent mounting seats are fixedly connected by bolts.

One end of the central tube is fixedly connected to a connection port, and the other end of the central tube is fixedly connected to an atomizing nozzle. A side mounting plate is fixedly connected to one side of the first limiting frame. A drive motor is fixedly connected to one side of the side mounting plate. A drive disc is fixedly connected to the output end of the drive motor. A connecting rod is installed between the drive disc and the central tube. The connection port is used to connect to a water supply component, and a flexible hose is required for the connection.

[0006] Preferably, one end of the connecting rod is fixedly connected to the drive disk, the other end of the drive disk is fixedly connected to a connecting ball, and a connecting block is fixedly connected to the outer surface of the middle tube.

[0007] Preferably, a limiting sleeve is fixedly installed on the outside of the connecting block, and the connecting ball is movably connected to the connecting block and the limiting sleeve.

[0011] Preferably, the outer surface of the mounting bracket is threaded with an adjustment component, and the lower end of the mounting bracket is fixedly connected to a base frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a dust suppression spraying device for building foundation pits, including a first limiting frame 1 and a second limiting frame 2. Mounting seats 3 are fixedly connected to the upper and lower parts of one end of the first limiting frame 1. Adjacent mounting seats 3 are fixedly connected by bolts. A rotating wheel seat 8 is rotatably connected between the first limiting frame 1 and the second limiting frame 2. A central tube 5 is fixedly connected inside the rotating wheel seat 8. One end of the central tube 5 is fixedly connected to a connection port 6, and the other end of the central tube 5 is fixedly connected to an atomizing nozzle 7. A side mounting plate 4 is fixedly connected to one side of the first limiting frame 1. A drive motor 14 is fixedly connected to one side of the side mounting plate 4. A drive disc 15 is fixedly connected to the output end of the drive motor 14. A connecting rod 16 is installed between the drive disc 15 and the central tube 5. The connection port 6 is used to connect to a water supply component, and a flexible hose must be used for the connection.

[0023] The specific settings and functions of this embodiment are described in detail below. By setting up the drive motor 14 and the rotating wheel seat 8, the middle tube 5 is driven to swing left and right, thereby increasing the coverage distance of the sprayed water mist. At the same time, the design structure is simple and easy to use. The separate design of the first limiting frame 1 and the second limiting frame 2 makes it easy to disassemble and remove the rotating wheel seat 8 for easy replacement. In addition, the swing frequency of the middle tube 5 can be adjusted according to the speed of the drive motor 14, making it convenient to use.

[0024] Example 2: Figures 1-4As shown, one end of the connecting rod 16 is fixedly connected to the drive disk 15, and the other end of the drive disk 15 is fixedly connected to the connecting ball 19. The outer surface of the middle tube 5 is fixedly connected to the connecting block 17, and the outer side of the connecting block 17 is fixedly installed with the limiting sleeve 18. The connecting ball 19 is movably connected to the connecting block 17 and the limiting sleeve 18. The lower ends of the second limiting frame 2 and the first limiting frame 1 are both fixedly connected to the extension base 20. A connecting base plate 9 is provided between the lower ends of the two extension bases 20. The connecting base plate 9 is fixedly connected to the first limiting frame 1 and the second limiting frame 2 by bolts. The lower end of the connecting base plate 9 is fixedly connected to the mounting block 13. A mounting frame 10 is provided below the connecting base plate 9. The mounting frame 10 is movably connected to the mounting block 13. The outer surface of the mounting frame 10 is threaded with the adjusting part 12. The lower end of the mounting frame 10 is fixedly connected to the base frame 11.

[0025] The overall effect of this embodiment is that by providing support through the extended base 20, the mounting base 3 can be prevented from contacting the connecting base plate 9, while the connection stability can be increased. Through the mounting block 13 and the mounting frame 10, the tilt angle of the first limiting frame 1 can be adjusted. With the mounting frame 10, it can be installed in different positions according to different dust suppression areas, and the appropriate angle can be adjusted for use. It has a wide range of applications and is simple and convenient to use.

[0026] The usage and working principle of this device are as follows: When in use, the base frame 11 is installed in the corresponding position according to the different dust suppression areas. Then, the angles of the first limiting frame 1 and the second limiting frame 2 are adjusted. The adjusting part 12 is rotated to squeeze the mounting block 13, thereby fixing the angles of the first limiting frame 1 and the second limiting frame 2. The connection port 6 is connected to the water supply equipment using a hose to supply water. The water is sprayed out from the atomizing nozzle 7 in the form of water mist. The drive disc 15 is started, causing the middle pipe 5 to swing, which is used for dust suppression in the foundation pit construction environment.
