The control mechanism comprises jacks 11 arranged on the top walls of the two fixing plates 7, stop rods 12 are vertically and movably inserted into the jacks 11, the side walls of the adjacent sides of the two stop rods 12 are inclined planes, and a driving mechanism matched with the baffle is arranged on the mounting frame 1.
The driving mechanism comprises a first elastic air bag 13 fixedly arranged on the inner top wall of the mounting frame 1, a first magnet 14 is fixedly arranged on the bottom wall of the first elastic air bag 13, and a second magnet 15 mutually attracted with the first elastic air bag 13 is fixedly arranged on the output end of the hydraulic rod 2;
a second elastic air bag 16 is fixedly arranged in the jack 11, and a conduit 17 communicated with the air inlet of the second elastic air bag 16 is fixedly arranged on the air inlet of the first elastic air bag 13;
a spring telescopic rod 18 matched with the guide plate 9 is fixedly installed on the side wall of the installation frame 1, and a steel ball 19 is fixedly installed at the output end of the spring telescopic rod 18.
Firstly, mounting a mounting frame 1 at a position between two adjacent air ducts, wherein the two air ducts are communicated under the action of holes; in an initial state, the hydraulic rod 2 and the electric telescopic rod 6 are both in a contraction state, the mounting plate 5 is located at one end, away from the front wall of the mounting frame 1, of the sliding groove 4, the top wall of the partition plate 3 is attached to the inner top wall of the mounting frame 1, and at the moment, air flow can normally penetrate through the hole in the mounting frame 1;
when needs are sealed with the wind channel, at first start hydraulic stem 2, hydraulic stem 2's output drives baffle 3 and moves down, baffle 3 moves to the dead ahead in the hole gradually in this process, when hydraulic stem 2 furthest moves down, start electric telescopic handle 6, electric telescopic handle 6 extends and drives mounting panel 5 and remove along spout 4 this moment, in this process, mounting panel 5 drives hydraulic stem 2 and installs baffle 3 on hydraulic stem 2 output and removes towards the direction of hole, when the installation moves to electric telescopic handle 6 furthest and extends, the lateral wall of baffle 3 and the laminating of the inside wall of installing frame 1, cover the surface at the hole for baffle 3 promptly, thereby can plug up the hole.
When the hydraulic rod 2 works, firstly the first magnet 14 and the second magnet 15 are attracted together, at this time, the output end of the hydraulic rod 2 pulls the first elastic air bag 13 downwards, at this time, the volume of the first elastic air bag 13 increases, and in this process, the inside of the first elastic air bag 13 is in a negative pressure state, so that the first elastic air bag 13 sucks air from the second elastic air bag 16 through the conduit 17, so that the inside of the second elastic air bag 16 is in a negative pressure state, therefore, the baffle rod 12 is driven to be retracted into the insertion hole 11 during the contraction of the second elastic air bag 16, since the air flow in the air duct enters the space between the baffle plate 9 and the side wall of the air duct, under the action of the air flow impact force, the baffle plate 9 drives the rotating rod 8 to rotate, at this time, the spring telescopic rod 18 is squeezed and has a restoring trend, and the two baffle plates 9 are in contact, at this time, the first elastic air bag 13 is in a maximally extended state, then the hydraulic rod 2 continues to be extended, at this time, the first magnet 14 is separated from the second magnet 15, and the attractive force between the first magnet 14 and the second magnet 15 is gradually reduced, when the elastic air bag 13 is smaller than the elastic air bag 13, the elastic air bag 13 is contracted, and the elastic air bag 13 again, the elastic air bag 16 pushes the elastic air bag 16 to flow back out of the second elastic air bag 16, and the insertion hole 16, and the second elastic air bag 16 again; when two guide plates 9 contact each other, the air current in the wind channel need pass the gas pocket 10 on the guide plate 9 and just can contact with baffle 3, pass the in-process of gas pocket 10 at the air current, the tiny particle that carries in air current and the air current all rubs with gas pocket 10 lateral wall each other, thereby turn into internal energy with the kinetic energy of tiny particle and air current, the impact force of tiny particle and gas to baffle 3 has been reduced, and when reducing tiny particle kinetic energy, the speed of tiny particle at 3 surface sliding of baffle has equally been reduced, the effect of the frictional force that 3 surface thermal insulation coating of baffle received has been reduced to the effect.
Before utilizing baffle 3 to block up the hole completely, baffle 3 does not contact with installing frame 1, consequently move down or be close to the in-process of installing frame 1 at baffle 3, the surface of baffle 3 only receives the frictional force of tiny granule in the air current, thereby the frictional force that 3 surface heat preservation coatings of baffle received has been reduced, the degree of wear of coating has been alleviateed, thereby can prevent that baffle 3 from leading to the surface unevenness under the effect of expend with heat and contract with cold, consequently, at spout 4, mounting panel 5, electric telescopic handle 6, under the combined action of guide plate 9, the effect of preventing 3 blocks puckery of baffle has been played.
When the hole on the mounting frame 1 is completely blocked by the partition plate 3, the airflow in the air duct stops impacting the guide plate 9, so that the guide plate 9 stops applying pressure to the spring telescopic rod 18, the spring telescopic rod 18 gradually recovers and pushes the guide plate 9 to rotate, in the rotating process of the guide plate 9, the guide plate 9 is in contact with the inclined plane on the stop rod 12, the stop rod 12 is pushed horizontally, the stop rod 12 starts to move upwards under the action of the component force of the thrust along the inclined plane and gradually retracts into the jack 11, and when the stop rod 12 retracts into the jack 11, the guide plate 9 passes through the bottom end of the stop rod 12, and the stop rod 12 extends out of the jack 11 again at the moment, so that the guide plate 9 can be fixed, and the function of preparing for the next work is achieved; and the spring telescopic link 18 is in the extruded in-process, and spring telescopic link 18 has the trend of restoring, and the output of spring telescopic link 18 promotes guide plate 9 this moment, and partial air current impact force that guide plate 9 received this moment has owing to guide plate 9 need overcome the thrust of spring telescopic link 18, consequently has further reduced the gas flow rate.
At guide plate 9 pivoted in-process, the outer wall of ball contacts with guide plate 9 all the time, because the ball surface is the curve, consequently the in-process that rotates and promote the ejector pin withdrawal sleeve at guide plate 9 has reduced the frictional force that the guide plate 9 lateral wall received to reduce the degree of wear of guide plate 9, prolonged the life of guide plate 9, reduced the frequency of maintenance, played the effect that improves work efficiency.
Specifically, as shown in fig. 7, the thermal insulation sleeves 20 made of aluminum silicate fiber are fixedly sleeved outside the first magnet 14 and the second magnet 15.
Since the alumina silicate fiber is a high temperature insulating material, the fire resistant temperature is 1000 to 1790 degrees, and the temperature in the flue is usually within 800 degrees, the first magnet 14 and the second magnet 15 can be prevented from being demagnetized due to heating by the insulating sleeve 20 which is formed by sheathing the alumina silicate fiber on the surfaces of the first magnet 14 and the second magnet 15, and the function of ensuring the normal mutual attraction of the first magnet 14 and the second magnet 15 is achieved.
Specifically, as shown in fig. 3, a cross bar 21 is horizontally installed in each air hole 10, and a spoiler 22 is movably sleeved on the cross bar 21.
The bottom wall of the spoiler is provided with a groove 23, and the side wall of the groove 23 far away from one side of the cross rod 21 inclines downwards.
When the air flow passes through the air holes 10, the spoiler 22 is impacted by the air flow, and the spoiler 22 rotates around the cross rod 21, so that the impact force of the smoke on the partition plate 3 is further reduced; because the holes are gradually blocked by the partition plate 3, the amount of the flue gas passing through the holes changes at any time, that is, the amount of the flue gas passing through the air holes 10 also changes at any time, the impact force applied to the spoiler 22 also changes at any time, so the spoiler 22 shakes up and down around the cross rod 21, the spoiler is in an inclined state in the shaking process of the spoiler 22, the air flows along the grooves 23 on the spoiler at the moment, and the flowing direction of the air flow is finally changed under the action of the inclined side walls of the grooves 23, the impact force of the air flow on the partition plate 3 is reduced again, and the abrasion degree of the heat-insulating coating on the surface of the partition plate 3 is reduced.
Specifically, as shown in fig. 3, a second mounting rod 24 is horizontally and fixedly mounted on the inner side walls of the opposite sides of the mounting frame 1, and a sleeve rod 25 is rotatably sleeved on the second mounting rod 24.
The ratio of the inner diameter of the loop bar 25 to the diameter of the second mounting bar 24 is 4:1, and the length ratio of the second mounting rod 24 to the loop bar 25 is 2:1.
in the process that the partition plate 3 moves downwards, airflow impacts the partition plate 3, and the power arm at the output end of the hydraulic rod 2 gradually increases along with the extension of the hydraulic rod 2, so that when the airflow impacts the partition plate 3, the partition plate 3 has a shaking trend, and therefore, the partition plate 3 can be blocked by the loop rod 25 by enabling the rear wall of the partition plate 3 to be in contact with the outer wall of the loop rod 25, so that the shaking frequency of the partition plate 3 is reduced, and the hydraulic rod 2 is prevented from being damaged; and the baffle 3 can be prevented from contacting with the inner side wall of the mounting frame 1 due to overlarge shaking amplitude, and the effect of ensuring the normal downward movement of the baffle 3 is achieved.
Because the loop bar 25 with larger inner diameter is movably sleeved on the second mounting bar 24, the friction force between the loop bar 25 and the partition plate 3 is rolling friction in the downward moving process of the partition plate 3, so that the friction force borne by the partition plate 3 is reduced, and the function of preventing the heat-insulating coating on the surface of the partition plate 3 from being worn is achieved while the shaking amplitude of the partition plate 3 is reduced; since the inner diameter of the loop bar 25 is 4 times the diameter of the second installation bar 24 and the length of the second installation bar 24 is 2 times the length of the loop bar 25, the loop bar 25 can be ensured to normally rotate even if the second installation bar 24 is thermally expanded.
Specifically, as shown in fig. 5, fixing rods 26 are uniformly and fixedly mounted on the side wall of the partition plate 3, a protection plate 27 is fixedly mounted on one end of each fixing rod 26, which is far away from the partition plate 3, and the ratio of the side area of the protection plate 27 to the side area of the partition plate 3 is 1:1.5 and the diameter of the fixing rod 26 is 5mm.
The side wall of the protection plate 27 is evenly and fixedly provided with a sloping plate 28, the sloping plate 28 is matched with the partition plate 3, and the sloping plates 28 are connected with one another at the head.
Because the side area of baffle 3 is 1.5 times of the side area of guard plate 27, consequently when guard plate 27 installs on the baffle 3 surface, the most part in baffle 3 surface is covered by guard plate 27, only the edge of baffle 3 exposes outside this moment, receive the frictional force of granule through reducing the baffle 3 edge and can protect baffle 3, and the area of contact of dead lever 26 with baffle 3 is less, consequently even dead lever 26 takes place deformation because of expend with heat and contract with cold and also can not lead to baffle 3 to take place deformation by a wide margin, consequently can ensure that the jam phenomenon can not appear between baffle 3 and the installing frame 1.
When flue gas flow direction baffle 3, the flue gas at first strikes the surface of protection plate 27, and the flue gas flows along the surface of protection plate 27 this moment, and consequently the flue gas removes from the direction conversion of initial perpendicular to baffle 3 to the direction on parallel baffle 3 surface, and when flue gas and protection plate 27 break away from the contact, the air current can flow along the surface of swash plate 28, has changed the direction of air current this moment, promptly: the air flow coming out of contact with the protection plate 27 has a tendency to flow in a direction away from the partition plate 3, so that this portion of the air flow can strike the air flow directly impacting the side wall of the partition plate 3, thereby reducing the impact force of the air flow on the surface of the partition plate 3 and functioning to protect the thermal insulation coating.
The working principle is as follows: when needs are sealed with the wind channel, at first start hydraulic stem 2, hydraulic stem 2's output drives baffle 3 and moves down, baffle 3 moves to the dead ahead in the hole gradually in this in-process, when hydraulic stem 2 furthest moves down, start electric telescopic handle 6, electric telescopic handle 6 extends and drives mounting panel 5 and remove along spout 4 this moment, in this process, mounting panel 5 drives hydraulic stem 2 and installs baffle 3 on 2 output of hydraulic stem and removes towards the direction of hole, when the installation moves to 6 furthest of electric telescopic handle and extends, the lateral wall of baffle 3 and the inside wall laminating of installing frame 1, cover the surface at the hole promptly for baffle 3, thereby can be with plugging up the hole.
When the hydraulic stem 2 during operation, at first magnet 14 and second magnet 15 adsorb together, the output of hydraulic stem 2 spurts first elasticity gasbag 13 downwards this moment, the volume increase of first elasticity gasbag 13 this moment, be in the negative pressure state in first elasticity gasbag 13 in this in-process, consequently first elasticity gasbag 13 breathes in from second elasticity gasbag 16 through pipe 17, thereby make the inside negative pressure state that is in of second elasticity gasbag 16, consequently will drive in the shrink in-process of second elasticity gasbag 12 will be by withdrawal jack 11, because the air current in the wind channel can get into in the space between guide plate 9 and the wind channel lateral wall, consequently under the effect of air current impact force, guide plate 9 drives dwang 8 and rotates, when two guide plate 9 contact each other, the air current in the wind channel need pass the gas pocket 10 on guide plate 9 and just can contact with baffle 3.
When the hole on the installing frame 1 is blocked up by baffle 3 completely, the air current in the wind channel stops to strike guide plate 9, therefore guide plate 9 stops spring telescopic link 18 to exert pressure, spring telescopic link 18 recovers gradually and promotes guide plate 9 and rotates this moment, at guide plate 9 pivoted in-process, guide plate 9 contacts with the inclined plane on pin 12, pin 12 receives the thrust of horizontal direction this moment, and under the effect of thrust along the component force on inclined plane, pin 12 begins to shift up, and retract in the jack 11 gradually, in the jack 11 of pin 12 withdrawal, guide plate 9 crosses the bottom of pin 12, pin 12 stretches out from jack 11 once more this moment, thereby can be fixed guide plate 9.
When the air flow passes through the air holes 10, the spoiler 22 is impacted by the air flow, and the spoiler 22 rotates around the cross rod 21, so that the impact force of the smoke on the partition plate 3 is further reduced; since the partition plate 3 gradually blocks the holes, the amount of the flue gas passing through the holes changes at any time, that is, the amount of the flue gas passing through the air holes 10 also changes at any time, so that the impact force applied to the spoiler 22 also changes at any time, the spoiler 22 shakes up and down around the cross bar 21, the spoiler is in an inclined state during shaking of the spoiler 22, the air flows along the grooves 23 on the spoiler, and the flowing direction of the air flow is finally changed under the action of the inclined side walls of the grooves 23.
In the process that the partition plate 3 moves downwards, airflow impacts the partition plate 3, and the power arm at the output end of the hydraulic rod 2 gradually increases along with the extension of the hydraulic rod 2, so that when the airflow impacts the partition plate 3, the partition plate 3 has a shaking trend, and therefore, the partition plate 3 can be blocked by the loop rod 25 by enabling the rear wall of the partition plate 3 to be in contact with the outer wall of the loop rod 25, so that the shaking frequency of the partition plate 3 is reduced, and the hydraulic rod 2 is prevented from being damaged; and also can prevent the baffle 3 because of shaking range contact with the inside wall of installing frame 1 when too big, in the baffle 3 process that moves down, the frictional force between loop bar 25 and baffle 3 is rolling friction, has reduced the frictional force that baffle 3 received.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
