One end of the first rotating shaft 63 is connected with the sleeving block 7, the other end of the first rotating shaft 63 is connected with the semicircular gear 6, and the first rotating shaft 63 plays a role in supporting the semicircular gear 6 and is beneficial to balance when the semicircular gear 6 rotates. The semicircular gear 6 is meshed with the transmission gear 61, the upper limiting block 81 and the lower limiting block 82 are respectively arranged on the valve rod 1 and are located inside the annular piece 5, the upper surface of the upper limiting block 81 is abutted against the upper surface inside the annular piece 5, and the lower surface of the lower limiting block 82 is abutted against the lower surface inside the annular piece 5. So that the valve rod 1 is driven to move up and down by the upper limit block 81 and the lower limit block 82 under the movement of the ring-shaped member 5.
Preferably, it includes idle rotation epicoele 211 and operation lower chamber 212 to rotate chamber 21, idle rotation epicoele 211 is the cylinder cavity, operation lower chamber 212 is the hexagonal prism cavity, idle rotation epicoele 211's diameter is greater than operation lower chamber 212, valve rod 1 is served and is equipped with the turning block 12 with operation lower chamber 212 assorted in the rotation chamber 21, turning block 12 is the hexagonal prism piece, makes valve rod 1 slide from top to bottom and makes the turning block 12 on the valve rod 1 move between idle rotation epicoele 211 and operation lower chamber 212 under the effect of extension spring 4.
When the rotating block 12 is located in the idle upper cavity 211, at this time, the rotating block 12 is located at the first station, and the rotation of the rotary disc 2 cannot drive the valve rod 1 to rotate; when the rotating block 12 is located in the operating lower cavity 212, at this time, the rotating block 12 is located at the second station, and since the rotating block 12 and the operating lower cavity 212 are both hexagonal prisms, the rotation of the rotary table 2 will drive the valve rod 1 to rotate, thereby driving the valve core to rotate.
Preferably, the driving shaft 62 is further provided with a driving hole 621, the driving hole 621 includes an arc portion 6211 and a triangular portion 6212, the indoor fire hydrant is further provided with an opening wrench 9, the opening wrench 9 includes an opening portion 91, an intermediate portion 92 and a handle portion 93, the opening portion 91 is arranged in parallel with the handle portion 93, one end of the intermediate portion 92 is connected with one end of the opening portion 91, the other end of the intermediate portion 92 is connected with the handle portion 93, and the intermediate portion 92 is arranged perpendicular to the opening portion 91;
the opening portion 91 includes an arc opening portion 911 and a triangular opening portion 912, the triangular opening portion 912 is provided on the arc opening portion 911, and the arc opening portion 911 and the triangular opening portion 912 are provided in a manner matching the arc portion 6211 and the triangular portion 6212, respectively. By inserting the opening portion 91 of the opening wrench 9 into the driving hole 621, the circular arc opening portion 911 of the opening portion 91 is engaged with the circular arc portion 6211 of the driving hole 621, and the triangular opening portion 912 of the opening portion 91 is engaged with the triangular portion 6212. Then, the handle 93 of the opening wrench 9 is rotated, so that the handle 93 rotates, and the rotation of the semicircular gear 6 is driven, and the ring 5 and finally the valve rod 1 are driven to move up and down.
Preferably, there are two semicircular gears 6, two driving shafts 62 and two first rotating shafts 63, and the two semicircular gears 6, the two driving shafts 62 and the two first rotating shafts 63 are symmetrically arranged. The arrangement of the symmetrical semicircular gear 6, the driving shaft 62 and the first rotating shaft 63 makes the rotation of the semicircular gear 6 more balanced during the rotation of the driving shaft 62, and increases the opening speed of the fire hydrant by reducing the force required to move the ring-shaped member 5 downward by the simultaneous rotation of the two driving shafts 62. In order to reduce the occurrence of the theft of the fire hydrant, the teeth of the semicircular gear 6 on one side are directed upward and the teeth of the semicircular gear 6 on the other side are directed downward by rotating the drive shaft 62 on one side. Therefore, when the driving shaft 62 is rotated simultaneously in the same clockwise direction, one of the semicircular gears 6 drives the ring-shaped member 5 to move upward, and the other semicircular gear 6 drives the ring-shaped member 5 to move downward, thereby further preventing the theft.
Preferably, when the fire hydrant needs to be opened for fire fighting, the triangular portion 6212 is positioned on the same vertical plane as the teeth on the semicircular gear 6, and the direction of the triangular portion 6212 is aligned with the direction of the teeth on the semicircular gear 6, so that the positions of the teeth of the semicircular gear 6 can be clearly known by the direction of the triangular portion 6212. When the tooth positions of the two semicircular gears 6 are different, the two semicircular gears 6 rotate in different clockwise directions to drive the annular part 5 to move in the same direction; when the teeth of the two semicircular gears 6 are at the same position, the annular member 5 can be driven to move in the same direction by rotating the two semicircular gears 6 in the same clockwise direction.
Preferably, one end of the valve rod 1, which is far away from the rotating block 12, is a prism body 11, and the prism body 11 is matched with the valve core.
The whole opening process of the fire hydrant is as follows: firstly, the opening wrench 9 extends into the driving hole 621, the opening wrench 9 is rotated to enable the driving shaft 62 to rotate, the driving shaft 62 drives the semicircular gear 6 to rotate, and the rotating semicircular gear 6 is matched with the transmission teeth 61 on the ring-shaped piece 5, so that the ring-shaped piece 5 is driven to move downwards. When the tension spring 4 is not subjected to external force, the rotating block 12 on the valve rod 1 is located in the idle rotation upper cavity 211, the annular part 5 moves downwards at the moment, the upper limiting block 81 is pushed to enable the valve rod 1 to move downwards, the valve rod 1 moves downwards to drive the rotating block 12 to move downwards to the operation lower cavity 212 from the idle rotation upper cavity 211, the prism part 11 on the valve rod 1 is matched with the valve core, and then the rotary disk 2 drives the valve rod 1 to rotate by rotating the rotary disk 2, so that the valve core is opened. When the valve rod 1 is not driven to move downwards by rotating the driving shaft 62, the rotating block 12 is still in the idle upper cavity 211, and the valve rod 1 cannot be driven to rotate no matter how the rotating disc 2 is rotated. And after the semicircular gear 6 is not matched with the transmission gear 61 any more, the ring-shaped part 5 moves upwards under the action of the tension spring 4, the ring-shaped part 5 pushes the lower limiting block 82 to move upwards, so that the valve rod 1 is driven to move upwards, and the rotating block 12 on the valve rod 1 is located in the idle upper cavity 211 again.
If the water thief lifts the rotary disc 2 upwards to enable the rotating block 12 to be located in the operating lower cavity 212, the valve rod 1 is not matched with the valve core, and therefore the valve core cannot be opened after the rotary disc 2 is rotated. If a water thief wants to press the rotary disc 2 downwards to enable the rotating block 12 to be located in the lower operating cavity 212, the situation cannot be achieved because the bottom end of the rotary disc 2 is abutted to the fixed block 3, the fixed block 3 is fixedly connected with the fire hydrant casing, and the rotary disc 2 cannot be pushed downwards. Therefore, the fire hydrant has strong water stealing prevention performance, fully ensures that the fire hydrant has sufficient water quantity and strong water pressure when in fire extinguishing, and improves the fire extinguishing efficiency.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
