Description

Technical Field

[0001] The present invention relates to the technical field of safe production, and in particular to a safe production reminder device and a use method thereof. Background Art

[0002] Production safety reminder devices are important devices used to remind people to pay attention to safety. They are widely used in various industrial and production environments to reduce accident risks and improve workplace safety.

[0003] In mines, smoke alarms are usually installed in key areas underground, such as coal mining faces, tunneling faces, electromechanical chambers, etc. Since there are a lot of coal dust and gas in these areas, once a fire or explosion occurs, the consequences will be disastrous. By installing smoke concentration detectors, the smoke concentration in these areas can be monitored in real time, and an alarm can be issued in time when an abnormality is found, thereby avoiding accidents.

[0004] In actual use, current smoke alarms are often directly installed on a support frame, which is exposed to the air. Due to the dusty working environment, a lot of dust will adhere to its surface. When the detection port is covered with dust, the concentration of harmful gases such as gas will be affected, and the monitoring accuracy will be affected, which will affect safety. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the invention

[0005] The purpose of the present invention is to provide a production safety reminder device and a method of using the same, which solves the problems raised in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a production safety reminder device, comprising a box, a smoke alarm is passed through the top of the box, an exhaust fan is fixedly connected to one end of the box, and an air intake pipe is passed through and fixed to the other end of the box, and further comprising:

[0007] A dustproof screen plate, which is slidably mounted on the outer end surface of the air intake pipe to prevent impurities from entering the air intake pipe;

[0008] Brushing components, the number of which is two, and the two brushing components are respectively attached to both sides of a side wall of the dustproof screen;

[0009] Blowing components, the number of the blowing components is two, and the two blowing components are respectively placed on both sides of the other side wall of the dustproof screen;

[0010] A driving assembly is connected to one side of the dustproof screen plate, and is used to drive the dustproof screen plate to rise and fall.

[0011] By adopting the above technical solution, in actual use, the exhaust fan is used to exhaust air, so that the gas is drawn into the box, and is filtered through the dustproof screen to avoid the invasion of impurities. The continuous gas passes through the box, and then the smoke alarm is used to monitor the smoke concentration. When it exceeds the standard, an alarm will be sounded to alert the staff to deal with it. When the outer wall of the dustproof screen is blocked, the starting drive component can drive the dustproof screen to move, so that the unused part of the dustproof screen can be replaced and moved to the air inlet for filtering. In the process of moving, the brushing component will brush and clean the blocked part of the dustproof screen, and at the same time, the blowing component will be started for blowing, so that high-pressure gas is used to blow to the dustproof screen in the opposite direction, so as to achieve secondary cleaning, which is beneficial to improve the cleaning effect. At the same time, the dust brushed down can be blown away to a farther position, which is beneficial to avoid the dust brushed down from accumulating at the dustproof screen, and thus it is beneficial to avoid the situation where the accumulated impurities are attached to the dustproof screen again when the gas is introduced into the box.

[0012] As a preferred embodiment of the present invention, the driving assembly comprises:

[0013] A servo motor, wherein the servo motor is fixed to a side wall of the air intake pipe, and a gear is fixedly connected to the outer end of the transmission shaft of the servo motor;

[0014] The rack is fixed to one side of the dustproof screen plate, and the rack is meshed with the gear.

[0015] By adopting the above technical solution, starting the servo motor can drive the gear to rotate, thereby driving the rack to move, and the rack will drive the dustproof screen to rise and fall.

[0016] As a preferred embodiment of the present invention, the brushing assembly includes:

[0017] A fixing strip, wherein the number of the fixing strips is two, and the two fixing strips are respectively arranged on both sides of a side wall of the dustproof screen plate;

[0018] The bristles are multiple in number, and the multiple bristles are fixed to a side wall of the fixing strip corresponding to the dustproof mesh plate, and the outer ends of the bristles are attached to the outer wall of the dustproof mesh plate.

[0019] By adopting the above technical solution, when the driving component drives the dustproof mesh plate to move up and down, the bristles will brush the dust on the outer wall of the dustproof mesh plate, thereby cleaning the attached dust and impurities.

[0020] As a preferred embodiment of the present invention, the blowing assembly comprises:

[0021] Hollow plates, the number of which is two, the two hollow plates are respectively arranged on both sides of the other side wall of the dustproof mesh plate, and one side wall of the hollow plate is provided with a plurality of evenly distributed holes;

[0022] Sleeves, the number of the sleeves is two, the two sleeves are respectively installed on both sides of the two hollow plates, the inner cavity of the sleeve is provided with an adapted piston, the outer wall of the piston is fixed with a push rod, the outer end of the push rod passes through the sleeve and is fixedly connected to the end surface of the dustproof mesh plate;

[0023] A one-way valve is fixedly connected to the outer wall of the sleeve, the outer end of the one-way valve is fixedly connected to an air outlet pipe, and the outer end of the air outlet pipe is connected to the hollow plate on the symmetrical side.

[0024] By adopting the above technical solution, during the lifting process of the dustproof mesh plate, the push rod on the lower side will drive the piston to move, thereby pressurizing the gas in the sleeve, and the gas is pushed into the hollow plate on the upper side, so that the gas is discharged along the holes and blown toward the dustproof mesh plate, thereby achieving secondary cleaning. Similarly, when the lifting plate descends, it will drive the piston in another sleeve to move, so that the other hollow plate can be cleaned by gas discharge.

[0025] As a preferred embodiment of the present invention, it also includes a control component, and the control component includes:

[0026] An end plate, one side of the end plate is hinged to the inner end of the air intake pipe, both side walls of the air intake pipe are fixed with springs, and the outer ends of the springs are fixedly connected to the side walls of the end plate;

[0027] A pressure switch is provided through the outer wall of the end plate and is arranged facing the end face of the air inlet pipe.

[0028] By adopting the above technical solution, the pressure switch and the servo motor are electrically connected. During normal use, the exhaust fan draws air, and the gas will push the end plate away to stretch the spring. When a lot of dust and impurities are blocked on the surface of the dustproof screen, the air intake volume is reduced, thereby weakening the thrust on the end plate. At this time, the spring pulls the end plate back to press the pressure switch on the inner end face of the intake pipe, thereby driving the drive assembly to drive the dustproof screen to rise and fall, thereby realizing automatic cleaning.

[0029] As a preferred embodiment of the present invention, it also includes a limit sliding assembly, which includes:

[0030] Slide rails, there are two slide rails, and the two slide rails are respectively fixed to the two side walls of the dustproof screen;

[0031] The sliders are two in number, and the two sliders are respectively slidably mounted on two slide rails, and the sliders are fixedly connected to the side wall of the air intake pipe through a connecting block.

[0032] By adopting the above technical solution, the dustproof screen plate is limited by the slider and the slide rail during the lifting process, thereby ensuring its high lifting stability.

[0033] As a preferred embodiment of the present invention, a lower side of one side wall of the sleeve is fixedly connected to an air intake valve.

[0034] As a preferred embodiment of the present invention, one end of the hollow plate is fixedly connected by a connecting frame and a fixing bar.

[0035] As a preferred embodiment of the present invention, connecting columns are fixed on both sides of one side wall of the hollow plate, and the connecting columns are fixedly connected to the air intake pipe.

[0036] The present invention also relates to a method for using a production safety reminder device, comprising the following steps:

[0037] Step 1: Use the exhaust fan to draw air into the box, and filter it through the dustproof screen to prevent impurities from invading. The continuous gas passes through the box, and then the smoke alarm is used to monitor the smoke concentration;

[0038] Step 2: When the outer wall of the dust screen is blocked, the control component will start the driving component to drive the dust screen to move, so as to replace the unused part of the dust screen to move to the air inlet for filtering, and the brush component will brush and clean the blocked part of the dust screen during the movement;

[0039] Step 3: The lifting of the dust screen will drive the push rod to push the piston, thereby pressurizing the gas in the sleeve, and then blowing air along the holes on the hollow plate, so as to use the high-pressure gas to blow back to the dust screen, thereby achieving secondary cleaning.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The present invention arranges the smoke alarm in the box, and then uses the exhaust fan to draw air, so as to draw the external gas into the box for monitoring, and can use the dustproof screen to filter, so as to prevent dust invasion, and can use the control component to realize automatic cleaning when the dustproof screen is blocked, so as to prolong the service life of the smoke alarm and improve the accuracy of detection;

[0042] The dust screen is driven to rise and fall by the driving component, so that it can be brushed and cleaned by the brushing component. In the process of driving the dust screen to rise and fall, the driving component can use the lifting and lowering of the dust screen to drive the push rod to move, thereby driving the blowing component to blow air, so as to use the back-blowing effect to blow away the debris remaining on the dust screen after brushing, thereby facilitating improving the cleaning effect.

[0043] The high-pressure gas generated by the blowing component can blow the brushed dust away to a farther location. While improving the cleaning effect, it helps to prevent the brushed dust from accumulating on the dustproof screen, which in turn helps to prevent the accumulated impurities from adhering to the dustproof screen again when the gas is introduced into the box.

The models of electrical appliances provided in the present invention are only for reference, and different models of electrical appliances with the same functions can be replaced according to actual usage.

[0059] See also Figure 1-6 The present invention provides a technical solution: a safety production reminder device, comprising a box body 1, a smoke alarm 11 is passed through the top of the box body 1, an exhaust fan 12 is fixedly connected to one end of the box body 1, and an air intake pipe 13 is passed through and fixed to the other end of the box body 1, and also includes:

[0060] A dustproof screen plate 14, which is slidably mounted on the outer end surface of the air inlet pipe 13 to prevent impurities from entering the air inlet pipe 13;

[0061] Brushing components, the number of which is two, and the two brushing components are respectively attached to both sides of a side wall of the dustproof mesh plate 14;

[0063] A driving assembly is connected to one side of the dustproof screen plate 14 and is used to drive the dustproof screen plate 14 to rise and fall.

[0064] It should be understood that in actual use, the exhaust fan 12 is used to exhaust air, so that the gas is drawn into the box body 1, and is filtered through the dustproof screen 14 to prevent impurities from invading. The continuous gas passes through the box body 1, and then the smoke alarm 11 is used to monitor the smoke concentration. When the smoke concentration exceeds the standard, an alarm will be sounded to alert the staff to deal with it. When the outer wall of the dustproof screen 14 is blocked, the starting drive component can drive the dustproof screen 14 to move, so as to achieve the replacement of the unused part of the dustproof screen 14 and move it to the air inlet for filtering. In the process of moving, the brushing component will brush and clean the blocked part of the dustproof screen 14, and at the same time, the blowing component will be started for blowing, so as to use high-pressure gas to blow back to the dustproof screen 14, so as to achieve secondary cleaning, which is beneficial to improve the cleaning effect. At the same time, the dust brushed down can be blown away to a farther position, which is beneficial to avoid the dust brushed down from accumulating at the dustproof screen 14, and thus it is beneficial to avoid the situation where the accumulated impurities are attached to the dustproof screen 14 again when the gas is introduced into the box body 1.

[0065] like Figure 1 and 2 , 3; the driving components include:

[0066] A servo motor 4, which is fixed to a side wall of the air intake pipe 13, and a gear 41 is fixedly connected to the outer end of the transmission shaft of the servo motor 4;

[0067] A rack 42, the rack 42 is fixed to one side of the dust screen 14, and the rack 42 is meshed with the gear 41;

[0068] It should be understood that starting the servo motor 4 can drive the gear 41 to rotate, thereby driving the rack 42 to move, and the rack 42 will drive the dust screen 14 to rise and fall.

[0069] like Figure 1 and 2 , 5; the brushing component includes:

[0070] Fixed strip 2, fixed strip 2, the number of fixed strips 2 is two, and the two fixed strips 2 are respectively arranged on both sides of one side wall of the dustproof screen plate 14;

[0071] Bristles 21, the number of bristles 21 is multiple, the multiple bristles 21 are fixed to a side wall of the fixing strip 2 corresponding to the dustproof screen plate 14, and the outer ends of the bristles 21 are attached to the outer wall of the dustproof screen plate 14;

[0072] It should be understood that when the driving component drives the dustproof mesh plate 14 to move up and down, the bristles 21 will brush the dust on the outer wall of the dustproof mesh plate 14, so as to clean the attached dust and impurities.

[0073] like Figure 1 and2 , 5; the blowing assembly includes:

[0074] Hollow plates 3, the number of hollow plates 3 is two, the two hollow plates 3 are respectively arranged on both sides of the other side wall of the dustproof mesh plate 14, and one side wall of the hollow plate 3 is provided with a plurality of evenly distributed holes 31;

[0075] Sleeve 34, the number of sleeves 34 is two, the two sleeves 34 are respectively installed on both sides of the two hollow plates 3, the inner cavity of the sleeve 34 is provided with an adapted piston 38, the outer wall of the piston 38 is fixed with a push rod 35, the outer end of the push rod 35 passes through the sleeve 34 and is fixedly connected to the end surface of the dustproof mesh plate 14;

[0076] The one-way valve 36 is fixedly connected to the outer wall of the sleeve 34 , and the outer end of the one-way valve 36 is fixedly connected to the air outlet pipe 33 , and the outer end of the air outlet pipe 33 is connected to the hollow plate 3 on the symmetrical side.

[0077] It should be understood that in the process of lifting the dustproof mesh plate 14, the push rod 35 on the lower side will drive the piston 38 to move, thereby pressurizing the gas in the sleeve 34, and the gas is pushed into the hollow plate 3 on the upper side, so that the gas is discharged along the hole 31 and blown to the dustproof mesh plate 14, thereby achieving secondary cleaning. Similarly, when the lifting plate descends, it will drive the piston 38 in another sleeve 34 to move, so that the other hollow plate 3 can be cleaned by exhausting gas.

[0078] Furthermore, connecting columns 32 are fixed on both sides of one side wall of the hollow plate 3, and the connecting columns 32 and the air intake pipe 13 are fixedly connected, thereby ensuring the stability of the hollow plate 3. It should be noted that the sleeve 34 can be externally installed and fixed through a mounting frame.

[0079] Furthermore, one end of the hollow plate 3 is fixedly connected to the fixing bar 2 via the connecting frame 22, so that when the hollow plate 3 is stable, the fixing bar 2 is also stable.

[0080] It is worth mentioning that an air intake valve 37 is fixedly connected to the lower side of one side wall of the sleeve 34. The setting of the air intake valve 37 enables the push rod 35 to use the air intake valve 37 to intake air when driving the piston 38 to slide outward, thereby ensuring air pressure balance.

[0081] like Figure 1 and 4 As shown, a control component is also included, and the control component includes:

[0082] An end plate 19, one side of the end plate 19 is hinged to the inner end of the air inlet pipe 13, and springs 17 are fixed to both side walls of the air inlet pipe 13, and the outer end of the spring 17 is fixedly connected to the side wall of the end plate 19;

[0083] The pressure switch 18 penetrates the outer wall of the end plate 19 and is arranged facing the end surface of the air intake pipe 13 .

[0084] It should be understood that the pressure switch 18 is electrically connected to the servo motor 4. During normal use, the exhaust fan 12 draws air, and the gas will push the end plate 19 away from the tension spring 17. When a lot of dust and impurities are blocked on the surface of the dustproof screen 14, the air intake volume is reduced, thereby weakening the thrust on the end plate 19. At this time, the spring 17 pulls the end plate 19 back so that the pressure switch 18 is pressed against the inner end surface of the intake pipe 13, thereby driving the drive assembly to drive the dustproof screen 14 to rise and fall, thereby realizing automatic cleaning.

[0085] like Figure 1 and 2 , 3, also includes a limit sliding assembly, the limit sliding assembly includes:

[0086] Slide rails 15, there are two slide rails 15, and the two slide rails 15 are respectively fixed to the two side walls of the dustproof screen plate 14;

[0087] The slider 16 includes two sliders 16 , which are slidably mounted on the two slide rails 15 , respectively. The slider 16 is fixedly connected to the side wall of the air inlet pipe 13 via a connecting block.

[0088] It should be understood that the dust screen plate 14 is limited by the slider 16 and the slide rail 15 during the lifting process, thereby ensuring the high lifting stability.

[0089] A method for using a production safety reminder device is as follows:

[0090] Step 1: The exhaust fan 12 is used to extract air, thereby drawing gas into the box 1, and filtering it through the dustproof screen 14 to prevent impurities from invading. The gas continues to pass through the box 1, and then the smoke alarm 11 is used to monitor the smoke concentration;

[0091] Step 2: When the outer wall of the dustproof screen 14 is blocked, the control component will start the start-up drive component to drive the dustproof screen 14 to move, so as to replace the unused part of the dustproof screen 14 and move it to the air inlet for filtering, and during the movement, the brushing component will brush and clean the blocked part of the dustproof screen 14;

[0092] Step 3: The lifting of the dust screen 14 will drive the push rod 35 to push the piston 38, thereby pressurizing the gas in the sleeve 34, and then blowing along the holes 31 on the hollow plate 3, so as to use the high-pressure gas to blow back to the dust screen 14, thereby achieving secondary cleaning.

The gas continuously passes through the box (1), and then the smoke alarm (11) is used to monitor the smoke concentration; Step 2: When the outer wall of the dustproof screen (14) is blocked, the control component will start the start-up drive component to drive the dustproof screen (14) to move, so as to achieve the replacement of the unused part of the dustproof screen (14) to move to the air inlet for filtering, and during the movement, the brushing component will brush and clean the blocked part of the dustproof screen (14); Step 3: The lifting and lowering of the dust screen (14) will drive the push rod (35) to push the piston (38), thereby pressurizing the gas in the sleeve (34), and then blowing along the holes (31) on the hollow plate (3), so that the high-pressure gas is blown back to the dust screen (14), thereby achieving secondary cleaning.
