Specific embodiment

With reference now to illustrating in accordance with a non-limiting embodiment of the present invention, it is construction and operation of for fire hydrant 12 Fig. 1 to Fig. 2 B of lock set 10.

Locked component 10 includes the delivery port covering (14A, 14B) of the delivery port 16 that can be fixed to fire hydrant 12.Water outlet Mouth covering includes Part I 14A and Part II 14B.With reference to Fig. 2A to Fig. 2 B, Part I 14A includes without limitation band There is the tubular The lid component 18 of hollow open cavity 20.Lock installation component 22 is such as threadably engaged or welds or any other Means for attachment is being fixed to the center of The lid component 18.Lock installation component 22 is formed with perforate 23.

Locking device is arranged in lock installation component 22.In the embodiment illustrated of Fig. 1, locking device includes key The cylinder locks 24 of operation.Cylinder locks 24 are fixed to into lock installation component 22 with nut 26.Cylinder locks 24 have lock core 28, the lock Core 28 can be rotated by the key (not shown) for authorizing, as is known in the art.Lock core 28 with key upstream end The contrary end in portion is attached to actuator 30.Actuator 30 is in shape cylindricality and is formed with the unlimited groove 32 in longitudinal direction (Fig. 1).Locking component 34, such as ball, in being arranged as the groove 32 for being received within actuator 30, such as will more fully below Explain.

Part II 14B includes without limitation center hub 36 (Fig. 2A and Fig. 2 B), and the center hub 36 is from round flange 38 Extend, it is convex that multiple perforates 40 (perforate 40 can be circumferentially spaced around the center of Part II 14B) are formed in the circle In edge 38.Center hub 36 is formed with one or more spines 42 (showing two in the embodiment illustrated of Fig. 1).

Part II 14B is sealably mounted on the delivery port 16 of fire hydrant 12 using the such as O-ring seals of seal 44. Part II 14B is such as fixed to delivery port 16 by bayonet connection 46.

Such as visible in Fig. 2A and Fig. 2 B, a part for Part II 14B and delivery port 16 is received within Part I 14A Hollow open cavity 20 in.In fig. 2 in shown latched position (that is, cylinder locks 24 are locked), Part I 14A Freely movable about Part II 14B rotations.In the latched position, locking component 34 is trapped in actuator 30 and not from lock peace The perforate 23 of dress component 22 is projected.In other words, in latched position, locking component 34 can be with Part I 14A and second 14B is divided to depart from, and Part I 14A can be rotated freely relative to delivery port 16.This prevents the unauthorized access of delivery port 16.Go out Mouth of a river covering seals fire hydrant to prevent hazardous material from invading.

In unlocked position as shown in fig. 2B (i.e. cylinder locks 24 are unlocked), actuator 30 is rotated, and is made Obtain locking component 34 to be projected into outside actuator 30 and perforate 23.Pin 48 (such as rolling pin) may be inserted into Part I 14A and second In the 14B of part so that two parts can mutually rotate, but be axially relative to one another movement by restriction.In the unlocked position, Locking component 34 can be pressed against the rotation stop wedge 42 of Part II 14B now so that the rotation of Part I 14A causes Part II The rotation of 14B, enables to remove Part II 14B from delivery port 16.In other words, in unlocked position, locking component 34 engagement Part I 14A and Part II 14B so that delivery port covering can remove to obtain to water from delivery port 16 Access.

In the embodiment in figure 1, locking device is mechanical.With reference now to illustrating another reality of the invention, Apply example to be construction and operation of Fig. 3 to Fig. 4 of the lock set for fire hydrant.The embodiment substantially with the embodiment phase of Fig. 1 Together, except the embodiment of Fig. 3 and Fig. 4 includes electromechanical locking devices 50, such as motor (for example, stepper motor or gear motor). May be provided on printed circuit board (PCB) 56 for the electromechanical locking of operation including the control electronic device 52 of one or more battery 54 Device 50.Covering 58 can be used for overlay electronic device and can be fixed to Part I 14A using screw 59.Electromechanical locking devices 50 can be operated by transponder (not shown) well known in the prior art.

With reference now to still further embodiment of the invention construction is illustrated, the lock for fire hydrant and to operate Fig. 5 of component.The embodiment is substantially identical with the embodiment of Fig. 3, except electromechanical locking devices 50 are by means of control electronics device Part 60 can be operated from the control centre 62 away from fire hydrant, and the control electronic device 60 is such as transceiver and with wireless Other electronic devices of communication work, such as, but not limited to infrared, bluetooth, RF, mobile phone communications, internet communication etc.. In this way, lock set can be opened from instruction (control) center 62 by telecommunication.Different covering 58A can be used for Overlay electronic device.

With reference now to the Fig. 6 for illustrating the override device 70 for lock set,.Override device 70 may include to obtain right The interface of the access of the disconnected element (for example, machine insurance device) in Part I 14A, it is described disconnect element be disconnected with Obtain the access to delivery port.For example, the disconnection of protector obtains the access in the perforate 40 of Part II 14B. Therefore, even if in latched position, it is also possible to access is obtained using override device 70 and rotates Part II 14B, so as to permit Perhaps delivery port covering is removed from delivery port.If fire department has lost the key of lock, this is probably useful.

Embodiments in accordance with the present invention, it is possible to provide sensor 72 (Fig. 2A), one of the sensing fire hydrant of the sensor 72 Hydraulic pressure in point.Sensor 72 can be the pressure sensor of the difference of the hydraulic pressure in the part for can alert fire hydrant.Pass Sensor can sense the operational factor of fire hydrant and the operational factor is sent to into control centre 62.

Different from all prior arts, terminal use can be provided with the selection for selecting to use which locking device Power：That is, mechanical locking, electromechanical locking devices or by can operate from the control centre away from fire hydrant locking dress Put.Used as another replacement, the present invention can be advantageously provided as external member.The locked component external member for being used for fire hydrant includes one group Locking device, each locking device includes the locking component that can be engaged with Part I and Part II, as described above.Lock It is mechanical locking to determine in device one, and another in locking device is in electromechanical locking devices, and locking device Another is the locking device that can be operated from the control centre away from fire hydrant.Terminal use selects application-specific to use Which locking device.
