Description

Technical Field

[0001] The utility model relates to the technical field of ventilation eyelets, in particular to a ventilation eyelet with a wind control function. Background Art

[0002] During the ore mining process, in order to ensure the flow of air in the mine, it is generally necessary to drill a ventilation hole (fixed size) at a specific location, namely the ventilation hole. Some ventilation holes are protected by grates at the ventilation holes to prevent larger debris from entering.

[0003] However, the existing ventilation holes have the following defects: 1. If the air volume of the ventilation holes is too large, it is easy to cause the air volume in other places in the mine to fail to meet the needs; 2. If a disaster occurs on the working face, such as gas (methane, carbon monoxide, hydrogen sulfide, ammonia and other toxic and harmful gases) diffusion, combustion, explosion, fire, etc., it will diffuse outward through the ventilation holes.

[0004] To this end, we have designed a ventilation eye with wind control function to solve at least one of the above-mentioned defects. Utility Model Content

[0005] The purpose of the utility model is to provide a ventilation eye with wind control function in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A ventilation eye with a wind control function comprises a ventilation cylinder with upper and lower openings, wherein the ventilation cylinder body is provided with a plurality of ventilation openings at even intervals along its circumference, and a sliding door that can be slid open and closed is provided inside the ventilation opening, and an outward opening door that can be opened and closed is hinged outside the ventilation opening; and a top plate is provided at the upper opening of the ventilation cylinder;

[0008] Wherein, the ventilator body is provided with a limiter for limiting the opening angle of the outward-opening door.

[0009] Preferably, the ventilation opening is located at the middle section of the ventilation cylinder body.

[0010] Preferably, an emergency door that can be opened and closed is provided in the middle of the top plate.

[0011] Preferably, the inner wall of the ventilation duct is provided with sliding rails cooperating with the sliding door at positions corresponding to the upper and lower sides of the ventilation opening.

[0012] Preferably, the cross-sectional outline of the ventilator is a circle or a regular polygon.

[0013] Preferably, a horizontal support frame is provided at the lower section of the inner cavity of the ventilator to increase the strength of the ventilator.

[0014] Preferably, the bottom of the ventilator is provided with an outer flange with a mounting hole to facilitate the installation and fixing of the ventilator.

[0015] Preferably, rollers are provided on both sides of the bottom of the sliding door to facilitate opening and closing of the sliding door.

[0016] Preferably, the inner cavity of the ventilation tube is provided with an opening and closing mechanism for adjusting the opening size of the sliding door.

[0017] Preferably, the opening and closing mechanism includes a screw motor coaxially arranged in the inner cavity of the ventilation duct and a guide column arranged in the inner cavity of the ventilation duct, the guide column is arranged parallel to the screw part of the screw motor, the screw part of the screw motor is threaded with a threaded slider, and the threaded slider is slidably connected to the guide column, and the threaded slider is universally hinged with an inclined connecting rod between the threaded slider and each sliding door.

[0018] The beneficial effects are:

[0019] 1. When in use, the outward-opening door can be opened, and then the sliding door can be opened according to the ventilation demand. That is, when the ventilation demand changes, the size of the opening and closing of the sliding door can be used to adapt to the change in ventilation demand, so as to prevent the technical problem that the air volume in other places of the mine cannot meet the demand; at the same time, when a disaster occurs on the working face, such as gas diffusion, combustion, explosion, fire, etc., the sliding door and the outward-opening door can be closed to prevent harmful gases from spreading outward through the ventilation holes; at the same time, when the external airflow is large, the outward-opening door facing the oncoming airflow will be closed under the action of the airflow, which can effectively prevent the external airflow from entering the ventilation duct, prevent the reverse flow of the airflow, and then prevent the toxic and harmful gases from entering other working faces after the disaster on the working face, and prevent the personnel on other working faces from being harmed;

[0020] 2. The setting of the opening and closing mechanism can make the screw part rotate through the operation of the screw motor, and the threaded slider moves upward or downward under the constraint of the guide column, thereby driving the inner end of the connecting rod to move up or down. Since the sliding door will not move up and down due to the constraint of the slide rail, the sliding door can only move in the horizontal direction, so that the sliding door can move to the open or closed position, and the function of adjusting the opening and closing size of the sliding door is realized.

[0021] The additional technical features and advantages of the present invention will be more clearly explained in the following description, or can be understood through the specific practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1, as Figure 1-3 As shown, a ventilation stand with wind control function comprises a ventilation tube 1 which is open at both top and bottom, a plurality of ventilation holes 11 are evenly spaced along the circumference of the ventilation tube 1, a sliding door 12 which can be slid open and closed is provided inside the ventilation hole 11, and an outward opening door 13 which can be opened and closed is hinged outside the ventilation hole 11; a top plate 2 is provided at the upper opening of the ventilation tube 1;

[0038] As needed, the inner wall of the ventilation duct 1 is provided with slide rails 14 cooperating with the sliding doors 12 at positions corresponding to the upper and lower sides of the ventilation opening 11; when the cross-sectional outer contour of the ventilation duct 1 can be circular, that is, the ventilation duct 1 is a cylinder, the slide rails 14 can be arc-shaped slide rails, and each group of arc-shaped slide rails corresponds to one of the sliding doors 12; the slide rails 14 can also be circular slide rails, so that all the sliding doors 12 are slidably connected to the slide rails 14; when the cross-sectional outer contour of the ventilation duct 1 can also be a polygon, such as a quadrilateral, pentagon, hexagon, heptagon, etc., preferably, the polygon is a regular polygon, and the slide rails 14 are linear slide rails, and each group of linear slide rails corresponds to one of the sliding doors 12.

[0039] As needed, the sliding door 12 can be a double door, that is, the sliding door 12 has a small door on each side; wherein, the cross-sectional outer contour of the ventilation duct 1 is taken as an example for explanation: in a specific embodiment, the ventilation duct 1 is cut and butt-welded using an iron plate with a thickness of 2 mm, and the top plate 2 is welded to the top surface of the ventilation duct 1 using a circular iron plate with a thickness of 2 mm; at this time, the vent 11 is arranged in the middle of the corresponding side wall of the ventilation duct 1, so that the two small doors on the left and right can be opened and closed.

[0040] Among them, the body of the ventilator 1 is provided with a limit member 3 for limiting the opening angle of the outward-opening door 13; as needed, the limit member 3 is arranged on the outer wall of the ventilator 1 corresponding to a position outside the rotation center of the outward-opening door 13, that is, when the outward-opening door 13 is opened to a certain angle, the outward-opening door 13 will abut against the limit member 3, preventing the outward-opening door 13 from continuing to open; as needed, the opening angle limit of the outward-opening door 13 is 40 to 50 degrees; 45 degrees is used for explanation, that is, when the outward-opening door 13 is opened 45 degrees outward, the outward-opening door 13 will abut against the limit member 3, and the outward-opening door 13 cannot continue to open.

[0041] As needed, the outward-opening door 13 has the function of closing and self-locking, that is, after the outward-opening door 13 is closed, it requires manual operation to open and cannot be opened autonomously; since closing and self-locking doors are already existing conventional technologies, such as house doors, etc., their structural principles will not be described in detail here.

[0042] As required, in order to facilitate the movement of the sliding door 12 , rollers are provided on both sides of the bottom of the sliding door 12 .

[0043] When this arrangement is used, the outward-opening door 13 can be opened, and then the sliding door 12 can be opened according to the ventilation demand, that is, when the ventilation demand changes, the size of the opening and closing of the sliding door 12 can be used to adapt to the change in ventilation demand, thereby preventing the technical problem that the air volume in other places in the mine cannot meet the demand; at the same time, when a disaster occurs on the working face, such as the diffusion of toxic and harmful gases such as methane, carbon monoxide, hydrogen sulfide, ammonia, combustion, explosion, fire, etc., the sliding door 12 and the outward-opening door 13 can be closed to prevent the harmful gas from diffusing outward through the ventilation hole; at the same time, when the external airflow is large, the outward-opening door 13 of the oncoming airflow will be closed under the action of the airflow, which can effectively prevent the external airflow from entering the ventilation duct 1, prevent the airflow from flowing in the opposite direction, and then prevent the toxic and harmful gases from entering other working faces after the disaster on the working face, thereby preventing the personnel on other working faces from being injured.

[0044] As needed, the vent 11 is located in the middle section of the ventilation tube 1; an emergency door 21 that can be opened and closed is provided in the middle of the top plate 2; this arrangement can gather lighter gases such as gas, and then discharge them from the emergency door 21 through professional means.

[0045] As needed, in order to facilitate the installation of the ventilation eye, an outer flange 15 with a mounting hole is provided at the bottom of the ventilation duct 1 to facilitate the installation and fixing of the ventilation duct 1; specifically, the outer flange 15 can be formed at the bottom of the ventilation duct 1 by welding angle irons.

[0046] As needed, in order to increase the strength of the ventilator 1, a horizontal support frame 4 is provided in the lower section of the inner cavity of the ventilator 1; when the cross-sectional outer contour of the ventilator 1 is a hexagon, the horizontal support frame 4 is a triangular structure. Specifically, the sharp corners of the horizontal support frame 4 are welded to the inner edges of the ventilator 1, so that each side rod of the horizontal support frame 4 forms a triangular structure with the side wall of the ventilator 1 outside it, thereby effectively increasing the strength of the ventilator 1.

[0047] Embodiment 1, as Figure 4-5As shown, a ventilation eye with wind control function, based on the first embodiment, in order to realize automatic control of the opening size of the sliding door 12; the inner cavity of the ventilation tube 1 is provided with an opening and closing mechanism 5 for adjusting the opening size of the sliding door 12; the opening and closing mechanism 5 comprises a screw motor 51 coaxially arranged in the inner cavity of the ventilation tube 1 and a guide column 52 arranged in the inner cavity of the ventilation tube 1, the guide column 52 is arranged in parallel with the screw part of the screw motor 51, the screw part of the screw motor 51 is screwed with a threaded slider 53, and the threaded slider 53 is slidably connected with the guide column 52, and the threaded slider 53 and each sliding door 12 are universally hinged with an inclined connecting rod 54, that is, the two ends of the connecting rod 54 are connected to the corresponding sliding door 12 and the threaded slider 53 through a universal joint. Specifically, the connecting rod 54 is inclined up and down and horizontally inclined, that is, the angle between the connecting rod 54 and the corresponding sliding door 12 door panel surface in the horizontal direction and in the vertical direction are both acute angles.

[0048] Specifically, the lead screw motor 51 and the guide column 52 are both installed on the horizontal support frame 4 .

[0049] As required, the lead screw motor 51 has a module for remotely receiving signals, that is, the operation of the lead screw motor 51 can be controlled by a corresponding remote controller to realize forward or reverse rotation of the lead screw portion of the lead screw motor 51 .

[0050] This arrangement allows the screw motor 51 to rotate when the size of the sliding door 12 needs to be adjusted, and the threaded slider 53 moves upward or downward under the constraint of the guide column 52, thereby driving the inner end of the connecting rod 54 to move upward or downward. Since the sliding door 12 is constrained by the slide rail 14 and cannot move up and down, the sliding door 12 can only move in the horizontal direction, so that the sliding door 12 can move to the open or closed position, thereby realizing the function of adjusting the size of the sliding door 12.

[0051] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
