Description

Technical Field

[0001] The present application relates to the field of automatic water sprinkling and dust suppression devices, and in particular to a main unit of an automatic water sprinkling and dust suppression device for mining. Background Art

[0002] Currently, working in mines generates large amounts of airborne dust, which not only interferes with workers' vision but also poses health risks. During material transportation, the dust accumulates on the surfaces of transport machinery, interfering with its operation and, over time, causing damage.

[0003] The existing automatic water sprinkler and dust suppression devices for mines are all controlled by the host to continuously or periodically spray dust removal water mist to absorb the dust in the air. When people or materials pass through the mine, the sensor installed on the mine will sense it and the host will control the water mist spraying device to stop working, and continue working after the people or materials pass through. The staff can check the working status of the equipment through the host and set the automatic water sprinkler and dust suppression device to work regularly or continuously.

[0004] The above-mentioned existing technical solutions have the following defects: the main unit of the automatic sprinkler device for mines is usually set on the wall of the mine, and the main unit shell is fixed to the wall with bolts. When the main unit needs to be replaced after long-term use, the bolts need to be removed from the inside of the main unit shell. This method is inconvenient for repairing and replacing the main unit. At the same time, since the wall of the mine is not flat, the installation stability of the main unit on the wall is poor, which increases the possibility of damage to the main unit after long-term use. Utility Model Content

[0005] In order to stably install the host on the wall and facilitate the maintenance and replacement of the host, the present application provides a host of an automatic water sprinkler and dust suppression device for mining.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A main unit of an automatic water sprinkler and dust suppression device for mining includes a main unit body, a mounting plate and a second fixing structure. The main unit body is arranged on the plate surface of the mounting plate. A positioning column is fixedly connected to the outer wall of the main unit body. A positioning hole is opened on the plate surface of the mounting plate. The positioning hole is adapted to the positioning column. The positioning column is detachably clamped in the positioning hole. The second fixing structure is arranged on the plate surface of the mounting plate away from the main unit body. The length of the second fixing structure is adjustable and can be fixed to the wall by bolts.

[0008] By adopting the above technical solution, the entire mounting plate can be aligned parallel to the wall on which the host is to be installed, using an adjustable second fixing structure. Bolts are used to secure the second fixing structure and the mounting plate to the wall. Compared to directly mounting the host on the wall, using the base to support the host can reduce the possibility of the host becoming loose after long-term use on an uneven wall. The provision of positioning holes and positioning posts allows the host body to be quickly positioned on the mounting plate. The positioning posts and positioning holes allow the host body to be removably mounted on the mounting plate, facilitating subsequent replacement and maintenance of the host during use and improving work efficiency.

[0009] Optionally, the main machine also includes a first fixed structure, which includes a rack and a half gear. A mounting cavity is provided in the mounting plate, and the mounting cavity opening is connected to the side wall of the mounting plate. The rack is slidably arranged in the mounting cavity opening, and the half gear is rotatably installed in the mounting cavity.

This first fixing structure allows the main unit to be quickly removed from and installed on the base, improving work efficiency and facilitating subsequent replacement and maintenance of the main unit.

[0011] Optionally, when the end face of the rack is in contact with the bottom surface of the mounting cavity, the half gear is inserted into the annular groove.

[0012] By adopting the above technical solution, the movement direction of the rack is clarified and the position of the rack is fixed, so as to avoid accidental collision causing the rack movement to interfere with the position of the half gear.

[0013] Optionally, the main unit also includes a limiting structure, which includes a fixed block, a limiting column and a spring. The fixed block is fixed in the installation cavity and spaced apart from the rack.

The two ends of the spring are respectively fixed to the fixed block and the limiting column. A first limiting hole is opened on the side wall of the rack. When the half gear is inserted in the annular groove, the spherical end of the limiting column is inserted in the first limiting hole.

[0014] By adopting the above technical solution, by setting a limit column and a first limit hole, the position of the rack is fixed, and the half gear is inserted into the annular groove of the positioning column to prevent the rack from sliding, thereby reducing interference with the half gear and making the main body more stably connected to the mounting plate.

[0015] Optionally, a second limiting hole is opened on the side wall of the rack, and the second limiting hole is on the same side as the first limiting hole and is arranged at intervals. When the center of the disengagement groove coincides with the center of the positioning hole, the spherical end of the limiting column is inserted into the second limiting hole.

[0016] By adopting the above technical solution, by setting a limiting column and a second limiting hole, the position of the rack is fixed, and the center of the arc surface that is out of the groove is coincided with the center of the positioning hole, the positioning column can be inserted into and pulled out of the positioning hole, thereby improving work efficiency.

[0017] Optionally, the second fixed structure includes a fixed tube, a movable tube, a top screw and an annular platform, one end of the fixed tube is fixedly connected to the mounting plate, the other end of the fixed tube is sleeved on the movable tube, the top screw passes through the outer wall of one end of the fixed tube away from the mounting plate, the annular platform is installed on the end face of the movable tube away from the mounting plate, and the inner diameter of the annular platform is smaller than the inner diameter of the movable tube.

[0036] Combine Figure 1 and Figure 2 The host body 1 includes a shell 11, a display screen 12, an interface 13 and a positioning column 14. The shell 11 is a box body made of one piece. The cover area of ​​the shell 11 is larger than the bottom area of ​​the box and the cover is detachably arranged on the box body. The display screen 12 is embedded in the cover of the shell 11. The display screen 12 can facilitate the staff to observe the operating status of the equipment. There are six interfaces 13. The interfaces 13 are hollow bolts. The interfaces 13 are symmetrically embedded in the opposite side walls of the shell 11 in groups of three. The interfaces 13 can be connected to the sensor and the electric ball valve through wiring, which is convenient for the host to control the operation of the automatic water sprinkling and dust reduction device. There are four positioning columns 14. The positioning columns 14 are installed on the outer wall of the shell 11 away from the display screen 12. The positioning columns 14 are distributed in a rectangular shape. The positioning columns 14 are made of one piece with the shell 11. An annular groove 141 is provided on the circumference of the positioning column 14. The annular groove 141 facilitates fixing the host body 1 on the base 2.

[0037] Combine Figure 1 and Figure 3 The base 2 includes a mounting plate 21 and a support plate 22. The mounting plate 21 is attached to and fixed to the outer wall of the bottom of the outer shell 11. The mounting plate 21 is arranged between the main body 1 and the second fixed structure 5. There are two support plates 22. The support plate 22 is a strip-shaped metal plate. One end of the support plate 22 is bent to form an inner and outer chamfer with an arc. The other end of the support plate 22 is fixed to the plate surface of the mounting plate 21. It is located at one end of the plate surface of the mounting plate 21. The plate surface of the inner chamfer of the support plate 22 is attached to the main body 1. The support plate 22 supports the main body 1. The support plate 22 can provide stable support for the main body 1 to prevent the main body 1 from falling during use. Positioning holes 23 are provided on the plate surface of the mounting plate 21. There are four positioning holes 23. The positioning holes 23 are adapted to the positioning columns 14. The positioning columns 14 can be detachably inserted into the positioning holes 23 to facilitate the installation and disassembly of the main body 1.

[0038] Combine Figure 3 and Figure 4The mounting plate 21 includes a main body of the mounting plate 21 and a cover plate connected to the main body by bolts. A mounting slot is provided on the surface of the main body of the mounting plate 21. The slot of the mounting slot communicates with a side wall of the main body of the mounting plate 21. The cover plate is detachably connected to the main body of the mounting plate 21 and can cover the mounting slot, thereby forming a mounting cavity 24. The positioning hole 23 is located on the main body of the mounting plate 21 and communicates with the mounting cavity 24. The main unit also includes a first fixing structure 3 disposed within the mounting cavity 24. The first fixing structure 3 includes a rack 31 and a half gear 32. The rack 31 is slidably disposed at the opening of the mounting cavity 24, with one section disposed within the mounting cavity 24. The length of the rack 31 is perpendicular to the length of the mounting plate 21, and the surface of the rack 31 is parallel to the surface of the mounting plate 21. The rack 31 has four teeth sections, which are evenly and spaced apart on two opposite side walls of the rack 31. The rack 31 is located at a section outside the mounting plate 21, which makes it convenient for staff to pull the rack 31.

[0039] Combine Figure 3 and Figure 4 There are four half gears 32, with teeth distributed along one section of their circumference, and the remaining sections being arcuate. The half gears 32 are rotatably mounted on the inner wall of the mounting cavity 24, with their planes parallel to the surface of the mounting plate 21. Each half gear 32 is mounted on one side of the positioning hole 23, with the half gears 32 spaced apart from the opening of the positioning hole 23. The four half gears 32 respectively mesh with the four sections of teeth on the rack 31. The half gears 32 secure the rack 31 and define its direction of movement. When the rack 31 moves, the meshing teeth drive the half gears 32 to rotate. A section of the arcuate surface of the half gear 32 mates with the annular groove 141 defined on the positioning column 14, and the section of the arcuate surface of the half gear 32 can be inserted into the annular groove 141. A disengagement groove 321 is defined on the half gear 32, located along a section of its arcuate surface. The arc radius of the disengagement groove 321 is consistent with the radius of the positioning hole 23.

[0040] Combine Figure 3 and Figure 4 When the rack 31 is pulled outward as a whole, the half gear 32 is driven to rotate until the center of the arc surface that is out of the groove 321 coincides with the center of the positioning hole 23, and the positioning post 14 is inserted into the positioning hole 23 until the outer wall of the shell 11 is in contact with the surface of the mounting plate 21, and the plane where the annular groove 141 is located coincides with the plane where the half gear 32 is located. The rack 31 is pushed inward to drive the half gear 32 to rotate. When the end face of the rack 31 is in contact with the bottom surface of the mounting cavity 24, a section of the arc surface of the half gear 32 is stuck into the annular groove 141, fixing the positioning post 14, thereby fixing the main body 1 to the base 2. The provision of the first fixing structure 3 facilitates the disassembly and installation of the main body 1 on the base 2, and is convenient for inspection, replacement and maintenance.

[0041] Combine Figure 3 and Figure 5The main unit also includes a limiting structure 4, which includes a fixed block 41, a limiting column 42 and a spring 43. The limiting structure 4 is arranged in the mounting cavity 24, and the limiting structure 4 is located on the side of the rack 31 away from the support plate 22. The fixed block 41 is fixedly connected to the mounting plate 21. The fixed block 41 is a square block, and the fixed block 41 and the rack 31 are spaced apart. A sliding hole 411 is provided on the side of the fixed block 41 close to the rack 31. The length direction of the limiting column 42 is perpendicular to the length direction of the rack 31. One end of the limiting column 42 is processed to form a spherical surface, and the other end of the limiting column 42 is slidably inserted into the sliding hole 411. The spring 43 is arranged in the sliding hole 411, and one end of the spring 43 is fixed to the bottom of the hole, and the other end of the spring 43 is fixed to the other end of the limiting column 42.

[0042] Combine Figure 3 and Figure 5 A first limiting hole 44 and a second limiting hole 45 are formed on the side wall of the rack 31. The limiting post 42 is adapted to fit within both the first and second limiting holes 44 and 45. When the half gear 32 secures the positioning post 14 within the positioning hole 23, the limiting post 42 is inserted into the first limiting hole 44, securing the position of the rack 31 and preventing it from sliding freely. This allows the half gear 32 to more stably engage the positioning post 14. The second limiting hole 45 is spaced apart from the first limiting hole 44. When the rack 31 is pulled outward from the mounting plate 21, the limiting post 42 disengages from the first limiting hole 44. When the disengagement groove 321 coincides with the center of the positioning hole 23, the limiting post 42 is inserted into the second limiting hole 45 to fix the position of the rack 31. The spring 43 can enable the limiting post 42 to disengage from the first limiting hole 44 or the second limiting hole 45 under the action of external force, thereby facilitating the installation and disassembly of the host body 1.

[0043] Combine Figure 3 and Figure 6The second fixed structure 5 includes a fixed tube 51, a movable tube 52, a top screw 53 and an annular platform 54. The second fixed structure 5 is provided with four groups. The fixed tube 51 is a round tube. The fixed tube 51 and the mounting plate 21 are integrally formed. An annular thickened portion is formed on the outer wall of one end of the fixed tube 51. The annular thickened portion is away from the mounting plate 21. The mounting plate 21 is provided with holes that pass through the plate body at the four groups of second fixed structures 5. The hole diameter is consistent with the inner diameter of the fixed tube 51 and the hole is coaxially arranged with the fixed tube 51. The movable tube 52 is a round tube. The movable tube 52 is slidably inserted into the fixed tube 51. The top screw 53 is threadedly connected to the thickened portion of the side wall of the fixed tube 51 and is fixed by the top screw 53 when the movable tube 52 and the fixed tube 51 are adjusted to the appropriate length. An annular platform 54 is located on the end face of the movable tube 52 facing away from the mounting plate 21. The inner diameter of the annular platform 54 is smaller than that of the movable tube 52 and the annular platform 54 is integrally formed with the movable tube 52. The annular platform 54 allows bolts to secure the main unit to a wall. The retractable second fixing structure 5 allows the main unit to adapt to various uneven surfaces, reducing the possibility of damage to the main unit.
