Description

A double power doorless weathertight shutter

technical field

The invention relates to the technical field of marine windows, in particular to a more convenient double-power doorless weathertight shutter.

Background technique

Doorless weathertight shutters are a substitute for steel shutters, especially suitable for places with high ventilation requirements, narrow operating space, and weathertight requirements. When the doorless weathertight shutters are to be installed at the height of the ship's chimney or on the outside of the ship's side, additional ladders and platforms are required, and it is usually difficult for ordinary operators to operate manually. The use of manual actuators to remotely control the blinds in this position has the advantage of easy operation. However, once the pneumatic system is damaged, it is inconvenient to maintain, and new hidden dangers will appear in an emergency.

Therefore, it is necessary to provide a new structure to solve the above problems.

Detailed ways

The present invention will be described in further detail below in conjunction with specific embodiments.

Example:

As shown in Figures 1 and 3, a doorless weathertight shutter of the present invention includes a frame 1, a pneumatic actuator 2 mounted on the frame 1 and a manual actuator 4, and the pneumatic actuator 2 or the manual actuator vertically Directly driven pull bars 3 and several louvers 11 pivotally connected to the frame 1 in parallel, the free edge of each louver 11 is pivotally connected to the pull bars 3 through a connecting rod 111, and several sealing strips 12 are fixed on the frame 1; When closed, the sealing strip 12 can close the gap between adjacent louvers 11 . When the louvers are closed, the pull bar 3 does not exert upward pulling force on each louver 11, and the louvers 11 droop naturally, and cooperate with the sealing strip 12 to isolate the air flow channel in the frame 1; when the louvers need to be opened, the pneumatic actuator 2 will make the pull bars 3 going up, the tie bar 3 will pull up all the louvers 11, so that the airflow can pass through the gaps between adjacent louvers 11. Pneumatic actuator 2 is powered by conventional compressed air, driven by a two-position five-way reversing valve installed on the operating platform, so people can control the action of pneumatic actuator 2 from a distance, and then change the opening and closing state of louvers 11. So this kind of shutter is suitable for use in high places.

As shown in Figures 1 and 2, the pneumatic actuator 2 includes a cylinder 21 fixed on the frame 1, a first rack 22 connected to the main shaft of the cylinder 21, a drive shaft 23 pivotally connected to the bottom of the frame 1, and a The second rack 33 below the pull bar 3 is provided with the first gear 24 engaged with the first rack 22 and the second gear 25 engaged with the second rack 33 on the drive shaft 23, and the second rack 33 is used for Lift the tie bar 3. When the main shaft of the cylinder 21 stretches out, the first rack 22 drives the first gear 24 to rotate downwards, driven by the drive shaft 23, the second rack 33 pulls up the pull bar 3, so that the shutter 11 can be opened; When the main shaft of the air cylinder 21 is retracted, the first rack 22 goes up and the first gear 24 rotates in the opposite direction, the second rack 33 stops lifting the stay bar 3, and the louver 11 makes the stay bar 3 descend under the action of its own weight.

As shown in Figures 2 and 4, the manual actuator 4 includes a box body 41 fixed in the frame 1, a worm shaft 42 and a worm 45 pivotally connected to the box body 41, the worm shaft 42 is parallel to the drive shaft 23, and the drive shaft 23 is fixed with a third gear 26, and the worm shaft 42 is provided with a fourth gear 44 meshed with the third gear 26 and a worm wheel 43 meshed with a worm 45, and a hand wheel 46 is fixed at the outer end of the worm 45. When the hand wheel 46 is turned, the worm gear 43 is driven to rotate the worm gear shaft 42, and then the fourth gear 44 drives the third gear 26 to rotate, so that the manual actuator 4 can use the mechanism on the pneumatic actuator 2 to adjust the posture of the shutter 11, so The shutter can be adjusted in two ways, pneumatic and manual, and has better universality.

As shown in Figures 2 and 4, the manual actuator 4 is also provided with a disengager 5, the disengager 5 includes a shift lever 51 pivotally connected to the box body 41, a shift fork 52 pivotally connected to the free end of the shift lever 51, and a to drive the stop pin 53 of the shift lever 51 to rotate; the worm gear shaft 42 has a chute 421 extending axially, the fourth gear 44 can slide along the chute 421, and the shift fork 52 is used to drive the fourth gear 44 to be in contact with the first The two positions of the three gears 26 meshing and non-engaging slide. The sliding groove 421 allows the radial position of the fourth gear 44 to be variable but can rotate together with the worm gear shaft 42 , and the radial position of the fourth gear 44 is adjusted by the shift fork 52 . When the pneumatic actuator 2 works, the manual actuator 4 will hinder the rotation of the drive shaft 23 through the third gear 26, so the stop pin 53 needs to be adjusted, and the shift fork 52 can switch the fourth gear 44 and the third gear 26 to disengage. open state, so that the manual actuator 4 will not hinder the normal operation of the pneumatic actuator 2; Rotate handwheel 46 and just can carry out the manual adjustment of shutter switch.

As shown in FIG. 3 , the brace 3 is provided with a plurality of vertically extending waist-shaped holes 31 , and the inner wall of the frame 1 is provided with protrusions 13 passing through the waist-shaped holes 31 . Because each waist-shaped hole 31 can only move vertically along the protrusion 13, the action of the tie bar 3 is limited to lifting movement, so as to prevent the tie bar 3 from being too slender and deformed after use.

As shown in Figure 1 and Figure 2, there are two braces 3 inside the frame 1, and the two braces 3 are connected to the two ends of the louver 11, and the drive shaft 23 is provided with two second rods that respectively drive one of the braces 3. Rack 25.

As shown in FIGS. 1 and 3 , a pair of lifting lugs 14 are arranged above the frame 1 . The lifting lugs 14 enable the frame 1 to be hoisted at a high place.

What have been described above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
