Description

Technical Field

[0001] The present invention belongs to the technical field of water sprinkling and dust reduction devices, and in particular relates to a water sprinkling and dust reduction device for mining. Background Art

[0002] A mine is an underground location where mineral resources are extracted. It includes a series of tunnels, shafts, working faces, and other facilities used for miner access, mineral transportation, ventilation, and drainage. The primary function of a mine is to access underground mineral resources to meet the needs of industrial production and social development. Mining operations (such as drilling, blasting, crushing, and transportation) generate large amounts of dust, which may contain harmful substances such as silicon dioxide (silica dust). Long-term inhalation of dust can lead to occupational diseases such as silicosis and respiratory diseases. Water sprinklers can effectively reduce airborne dust concentrations and mitigate worker exposure risks.

[0003] However, the above patent has the following shortcomings:

[0004] 1. Existing water sprinkler dust suppression devices in mines are generally divided into two types. One type is a sprinkler nozzle fixed on a fixed pipe. This method can reduce the size of the sprinkler device. However, as the mine is developed, the nozzle on the original pipe will lose its function. The nozzle itself is fixed, so it is difficult for the position and angle of the nozzle to be easily adjusted except by the pipe workers.

[0005] The other is a water-storing sprinkler, but the size of this type of sprinkler is generally large, while the space in the mine is generally small, making it inconvenient to place this type of sprinkler.

[0006] Because there is a lot of dust in the mine, the nozzle holes of the nozzles installed in the mine are easily clogged by dust when not in use. Although the existing nozzles in the mine are equipped with dust-proof structures such as dust covers, the passive dust-proof structure is easily forgotten by users, and thus the original dust-proof effect cannot be achieved. Summary of the Invention

[0007] The present invention provides a water sprinkling and dust suppression device for mines, which aims to solve the problem mentioned in the background art above that the existing water sprinkling and dust suppression devices in mines are generally divided into two types. One type is a sprinkler nozzle fixedly installed on a fixed pipe. This method can reduce the size of the sprinkler device. However, as the mine is developed, the nozzle on the original pipe will lose its function. The nozzle itself is fixed, so the position and angle of the nozzle cannot be easily adjusted except by the pipe workers.

[0008] The other is a water-storing sprinkler, but the size of this type of sprinkler is generally large, while the space in the mine is generally small, which makes it inconvenient to place this type of sprinkler.

[0009] The present invention is achieved by providing a water sprinkling and dust suppression device for mining, comprising a connecting pipe, flanges at both ends of the connecting pipe, a plug-in sleeve above the connecting pipe, a connecting structure between the plug-in sleeve and the connecting pipe, and the connecting structure is used for quickly fixing the plug-in sleeve and the connecting pipe;

[0010] A nozzle is provided above the plug-in cylinder, and an adjustment mechanism is provided between the plug-in cylinder and the nozzle, and the adjustment mechanism is used to adjust the spray angle of the nozzle;

[0011] A protective mechanism is provided above the nozzle, and the protective mechanism is used to prevent the nozzle from being exposed to the mine environment when not in use.

[0012] Preferably, the connection structure includes a fixed cylinder and a plug-in cylinder, the middle portion of the fixed cylinder is arranged through the top of the connecting pipe, the fixed cylinder is fixedly connected to the connecting pipe, a slot is opened through the top of the fixed cylinder, a sealing member is slidably connected inside the fixed cylinder, and the bottom of the fixed cylinder is threadedly connected to the connecting cylinder;

[0013] The outer circumference of the connecting tube is provided with a plurality of filter holes, and a return spring is provided inside the connecting tube. The top of the return spring abuts against the seal, and the bottom of the return spring abuts against the inner wall of the connecting tube. The plug-in tube matches the slot, and through grooves are provided on both sides of the bottom of the plug-in tube. A locking structure is provided between the plug-in tube and the connecting pipe.

[0014] In the initial state, the seal is squeezed by the return spring, which can drive the seal to abut against the slot on the top of the fixed cylinder, thereby completing the sealing of the slot. At this time, the water flow in the connecting pipe will not leak to the outside of the connecting pipe;

[0015] When the nozzle needs to be connected to the connecting pipe, first insert the plug-in cylinder into the slot. At this time, the end of the plug-in cylinder will squeeze and drive the seal to move downward in the fixed cylinder. At the same time, the return spring will be squeezed and compressed by the seal until the fixing ring on the outer periphery of the plug-in cylinder is against the fixed cylinder. At this time, the water in the connecting pipe can enter the connecting cylinder through the filter hole on the surface of the connecting cylinder, and then the water in the connecting cylinder will enter the plug-in cylinder through the through groove on the surface of the plug-in cylinder.

[0016] Preferably, the locking structure includes a fixing member and a fixing ring, the number of the fixing members is set to two, the two fixing members are respectively fixedly connected to the two sides of the connecting pipe, and the side walls of the two fixing members are each provided with a card slot, and the two card slots face opposite directions;

[0017] The fixing ring is sleeved on the outer circumference of the plug-in tube, the fixing ring is fixedly connected to the plug-in tube, the first connecting rods are fixedly connected to both sides of the fixing ring, the ends of the two first connecting rods are fixedly connected to the limiting members, the side walls of the two limiting members are fixedly connected to the extension rods, and the ends of the two extension rods are eccentrically hinged with fasteners;

[0018] After the plug-in tube is inserted into the slot and the fixing ring on the outer circumference of the plug-in tube is against the fixing tube, the fixing ring is rotated. At this time, the fixing ring will drive the two extension rods to engage with the slots on the side walls of the two fixing parts through the first connecting rods and the limit members on both sides. Then, the two fasteners are pressed respectively to drive the two fasteners to rotate. When the two fasteners rotate, they will pull the two extension rods respectively. At the same time, the two extension rods will pull the fixing rings respectively through the two limit members and the two first connecting rods, and then against the fixing tube through the fixing ring, thereby completing the fixation between the plug-in tube and the fixing tube.

[0019] Preferably, the adjustment mechanism includes a mounting ring, two second connecting rods are fixedly connected between the mounting ring and the fixing ring, the inner wall of the mounting ring is set to be arc-shaped, the bottom of the mounting ring is provided with a locking ring, the inner wall of the locking ring is set to be arc-shaped, the locking ring is threadedly connected to the mounting ring, a universal ball is provided between the locking ring and the mounting ring, a connecting pipe is passed through the middle of the universal ball, the connecting pipe is fixedly connected to the universal ball, the top of the connecting pipe is connected to the nozzle, and the bottom of the connecting pipe is connected to the plug-in cylinder with a metal bellows;

[0020] In the initial state, the universal ball is limited between the mounting ring and the locking ring. By turning the connecting tube, the universal ball can be driven to deflect in any direction, so that the connecting tube and the universal ball can be turned to the required angle, and then the nozzle connected to the connecting tube can be adjusted to the appropriate angle. After that, the locking ring can be rotated to bring the locking ring closer to the mounting ring, so that the universal ball can be locked, and then the connecting tube and the nozzle can be locked.

[0021] Preferably, the protective mechanism includes a mounting plate and a mounting groove, the mounting plate is sleeved on the outer circumference of the connecting pipe, the mounting plate is fixedly connected to the connecting pipe, mounting rods are hingedly provided on both sides of the mounting plate, and protective covers are fixedly connected to the tops of the two mounting rods, and the two protective covers are matched with the nozzle;

[0022] The mounting groove is opened in the middle of the connecting pipe, a sealing ball is rotatably arranged in the middle of the mounting groove, a circulation groove is penetrated in the middle of the sealing ball, a first sealing ring is provided on both sides of the sealing ball, a rotating shaft is fixedly connected to the top of the sealing ball, the middle of the rotating shaft penetrates the connecting pipe, the rotating shaft is rotatably connected to the connecting pipe, a first rotating disk is fixedly connected to the top of the rotating shaft, an eccentric shaft is eccentrically fixedly connected to the top of the first rotating disk, a second rotating disk is fixedly connected to the top of the second rotating disk, a knob is fixedly connected to the top of the second rotating disk, and a movable sleeve is provided on the outer periphery of the eccentric shaft. The cam is fixedly provided with a movable rod, and a limit slot is provided in the middle of the movable rod. A hinged rod is provided between the end of the movable rod and the two mounting rods. One end of the two hinged rods is hingedly provided with the end of the movable rod, and the other end of the two hinged rods is hingedly provided with the end of the two mounting rods respectively. A limit rod is provided through the middle of the movable rod, and the limit rod is slidably connected to the movable rod. The top end of the limit rod is fixedly connected to the mounting plate, and the bottom end of the limit rod is fixedly connected to the limit block, and the limit block is slidably connected to the limit slot.

[0023] By turning the knob, the sealing ball can be driven to rotate in sequence through the second rotating disk, the eccentric shaft, the first rotating disk and the rotating shaft. When the two ends of the internal flow groove of the sealing ball correspond to the two first sealing rings respectively, the communicating pipe is in a communicating state. Then, the sealing ball can be rotated to make the two ends of the internal flow groove of the sealing ball staggered with the two first sealing rings respectively, so that the two first sealing rings and the sealing ball abut against each other, thereby sealing the communicating pipe.

[0024] When the inside of the connecting pipe is in a connected state, the two protective shells are in an expanded state. At this time, the eccentric shaft can be driven to rotate eccentrically through the second rotating disk by rotating the knob. When the eccentric shaft rotates eccentrically, it will drive the movable sleeve to move upward. At this time, the movable sleeve will drive one end of the two hinged hinged rods to move upward through the moving rod. At the same time, the other ends of the two hinged rods will respectively squeeze the two mounting rods, thereby driving the two mounting rods to rotate respectively. At the same time, the two mounting rods will respectively drive the two protective covers to close, and the connecting pipe is in a closed state. After that, resetting the rotary knob can drive the two protective covers to open, and the connecting pipe is in an expanded state. Therefore, through the above structure, the two protective covers will be opened in conjunction when the nozzle is opened, and the two protective covers will be closed in conjunction when the nozzle is closed, so that the nozzle can be automatically protected when not in use, thereby preventing the nozzle from being blocked by dust in the mine tunnel when the nozzle is not in use.

[0025] Preferably, the edges of the two protective covers are provided with sealing strips, the tops of the two protective covers are fixedly connected with magnets, and the magnetic poles of the two magnets are opposite;

[0026] When the two protective covers are close to each other, the magnetic attraction of the two magnets can improve the fit between the two protective covers, thereby improving the fit between the two sealing strips, thereby avoiding the formation of gaps between the protective covers, which allows dust in the mine to enter the interior of the protective covers.

[0027] Preferably, an annular pad is sleeved on the outer circumference of the two extension rods, and the two annular pads are respectively slidably connected to the two extension rods, and the two annular pads are made of rubber material. A second sealing ring is sleeved on the outer circumference of the plug-in cylinder, and the second sealing ring is slidably connected to the plug-in cylinder, and the second sealing ring matches the fixed cylinder;

[0028] When the two fasteners are pressed to drive the two fasteners to rotate, the two fasteners will rotate and pull the two extension rods respectively. At this time, the extension rod will drive the limiting part and the fixing part closer, thereby squeezing the annular gasket sleeved on the outer circumference of the extension rod. The deformed annular gasket can fill the gap between the limiting part and the fixing part so that the fasteners can continue to resist the fixing part, thereby preventing the extension rod and the fixing part from slipping. The second sealing ring can fill the gap between the fixing ring and the fixing tube, thereby improving the sealing performance between the plug-in tube and the connecting pipe.

[0029] Preferably, a convex ring is fixedly connected to the outer periphery of the connecting tube, and an anti-slip groove is opened on the outer periphery of the convex ring. The number of the anti-slip grooves is set to multiple, and the multiple anti-slip grooves are distributed around the center of the convex ring;

[0030] By arranging a convex ring on the outer periphery of the connecting tube and opening multiple anti-slip grooves on the outer periphery of the convex ring, the connecting tube can be easily rotated, thereby facilitating the rotation of the connecting tube to separate the connecting tube from the fixed tube, thereby facilitating the replacement of the connecting tube and further facilitating the cleaning of the filter holes on the surface of the connecting tube.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: a water sprinkling and dust reduction device for mining of the present invention:

[0032] 1. When laying pipes in the mine, connect the connecting pipes at the joints of the pipes according to the location where water needs to be sprinkled. Then, according to the location where water needs to be sprinkled, quickly fix the sprinkler head and the connecting pipe at this location through the connecting structure and connect them. Then, the sprinkler head can be used for watering.

[0033] By connecting the connecting pipe during the water pipe laying process, the volume required for the device can be reduced, thereby facilitating the laying of the device. In the process of mine development, the nozzle structure on the connecting pipe in the previously abandoned area can be quickly disassembled and installed on the required connecting pipe without the need for professional plumbers, so as to facilitate the reuse of the nozzle. At the same time, the spray angle of the nozzle can be adjusted in conjunction with the adjustment mechanism.

[0034] By setting up a protective mechanism, the two protective covers will open in conjunction when the nozzle is opened, and will close in conjunction when the nozzle is closed, so that the nozzle can be automatically protected when not in use, thereby preventing the nozzle from being blocked by dust in the mine tunnel when the nozzle is not in use.

[0067] The working principle and use process of the present invention:

[0068] When laying pipes in a mine, the connecting pipe 1 is connected to the connection point of the pipe according to the location where water is required to be sprinkled. When the sprinkler head 13 needs to be connected to the connecting pipe 1, the plug-in cylinder 12 is first inserted into the slot 23. At this time, the end of the plug-in cylinder 12 will squeeze and drive the seal 24 to move downward in the fixed cylinder 21. At the same time, the return spring 27 will be squeezed and compressed by the seal 24 until the fixing ring 222 on the outer periphery of the plug-in cylinder 12 is against the fixed cylinder 21. At this time, the water in the connecting pipe 1 can enter the connecting cylinder 25 through the filter hole 26 on the surface of the connecting cylinder 25. After that, the water in the connecting cylinder 25 will enter the plug-in cylinder 12 through the through groove 28 on the surface of the plug-in cylinder 12. When the plug-in cylinder 12 is plugged into the slot 23 After the fixing ring 222 on the outer periphery of the plug-in cylinder 12 abuts against the fixing cylinder 21, the fixing ring 222 is rotated. At this time, the fixing ring 222 drives the two extension rods 226 to engage with the slots 223 on the side walls of the two fixing members 221 through the first connecting rods 224 and the limiting members 225 on both sides. Then, the two fasteners 227 are pressed respectively to drive the two fasteners 227 to rotate. When the two fasteners 227 rotate, they pull the two extension rods 226 respectively. At the same time, the two extension rods 226 pull the fixing ring 222 through the two limiting members 225 and the two first connecting rods 224 respectively, and then abut against the fixing cylinder 21 through the fixing ring 222, thereby completing the fixation between the plug-in cylinder 12 and the fixing cylinder 21;

[0069] In the initial state, the universal ball 34 is limited between the mounting ring 31 and the locking ring 33. By turning the connecting tube 35, the universal ball 34 can be driven to deflect in any direction, so that the connecting tube 35 and the universal ball 34 can be turned to a desired angle, and then the nozzle 13 connected to the connecting tube 35 can be adjusted to a suitable angle. Thereafter, by rotating the locking ring 33, the locking ring 33 and the mounting ring 31 are brought closer together, so that the universal ball 34 can be locked, and then the connecting tube 35 and the nozzle 13 can be locked.

[0070] By turning the knob 412, the sealing ball 45 can be rotated in sequence via the second rotating disk 411, the eccentric shaft 410, the first rotating disk 49, and the rotating shaft 48. When the two ends of the internal flow groove 46 of the sealing ball 45 correspond to the two first sealing rings 47, the connecting pipe 35 is in a connected state. Then, by rotating the sealing ball 45 90 degrees, the two ends of the internal flow groove 46 of the sealing ball 45 are staggered with the two first sealing rings 47, so that the two first sealing rings 47 abut against the sealing ball 45, thereby sealing the connecting pipe 35.

[0071] When the interior of the connecting pipe 35 is in a connected state, the two protective shells are in an expanded state. At this time, the eccentric shaft 410 can be driven to rotate eccentrically through the second rotating disk 411 by rotating the knob 412 90 degrees. When the eccentric shaft 410 rotates eccentrically, it will drive the movable sleeve 413 to move upward. At this time, the movable sleeve 413 will drive one end of the two hinged hinged rods 416 to move upward through the moving rod 414. At the same time, the other ends of the two hinged rods 416 will respectively squeeze the two mounting rods 43, thereby driving the two mounting rods 43 to rotate respectively. At the same time, the two mounting rods 43 will respectively drive the two protective covers to close, and the connecting pipe 35 is in a closed state. After that, resetting the rotating knob 412 can drive the two protective covers to open, and the connecting pipe 35 is in an expanded state. Therefore, through the above structure, when the nozzle 13 is opened, the two protective covers will be linked to open, and when the nozzle 13 is closed, the two protective covers will be linked to close, so that the nozzle 13 can be automatically protected when it is not in use, thereby preventing the nozzle 13 from being blocked by dust in the mine tunnel when the nozzle 13 is not in use.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
