Abstract
The invention discloses a valve locking device for an armored withdrawable switch cabinet. A movable plate, a baffle and a limiting plate are horizontally placed in sequence from top to bottom. A longitudinal slotted hole I is formed in the rear protruding part of the right end of the movable plate. The limiting plate is fixed to a cabinet body, and a transverse slotted hole II is formed in the middle of the limiting plate. A round hole is formed in the middle of the baffle. A bolt I penetrates through the slotted hole I, the slotted hole II and the round hole in sequence from top to bottom. A bolt II penetrates through the front right end of the movable plate and the front right end of the limiting plate in sequence from top to bottom, so that the movable plate and the limiting plate are hinged. The rear end of a spring is fixed to the rear left end of the limiting plate, and the front end of the spring is fixed to the rear end of the rear protruding part of the movable plate. The valve locking device has the advantages of being flexible, convenient to use, safe, reliable and easy to install.
Description
Technical field
The present invention relates to a kind of switch cabinet shutter blocking device.
Background technology
Currently, along with KYN28A-12 (Z) series armor removing high-voltage switch extensive application in 10kV distribution system, its operation maintenance safety is increasingly subject to the attention of user.Wherein, it is prevented that cabinet valve opens by mistake measure and becomes more and more important.
Cabinet design originally, mainly from the viewpoint of the safety of the degree of protection equipment of cabinet profile and personnel.But in real work, the situation of power-on serving breaker chamber can be encountered.When safeguarding, valve is likely opened by mistake by instrument and opens or personnel's maloperation is opened.Once valve is opened, very easily cause electric shock accidents.
Summary of the invention
For solving the above-mentioned purpose that prior art exists, the invention provides a kind of novel withdraw-type switch cabinet valve locking device, its technical scheme taked is:
Including dynamic plate, baffle plate, limiting plate, bolt I, bolt II and spring, dynamic plate, baffle plate and limiting plate horizontal positioned from top to bottom successively, dynamic plate is the handle structure of right-hand member processus aboralis, the processus aboralis part of dynamic plate right-hand member has longitudinal long slot bore I, limiting plate is fixed on cabinet, limiting plate centre position has horizontal long slot bore II, baffle plate has circular hole on centre position, bolt I sequentially passes through long slot bore I from top to bottom, long slot bore II and circular hole, bolt II sequentially passes through the right front ends of dynamic plate and the right front ends of limiting plate from top to bottom, plate and limiting plate is made to be hinged, and dynamic plate can bolt II be that axle rotates, the rear end of spring is fixed on the left back end of limiting plate, its front end is fixed on the rear end of dynamic plate processus aboralis part；When dynamic plate and handcart shake the angle into direction be 60 ° time, the left side of baffle plate is stuck in the opening position of upper plate and lower plate, makes baffle plate engage with upper plate and lower plate, and bolt I is positioned at the rear end of long slot bore I, bolt I is positioned at the left end of long slot bore II simultaneously, and now spring is in nature compressive state.
The present invention is truly realized automatic blocking, it is not necessary to manual operation.Closedown mode is forced blocking, when effectively preventing chopper to extract out, valve is subjected to displacement under external force, ensure that the personal safety of operator, the generation of electric shock accidents is avoided root, effectively prevent and move after parts (such as handcart) remove at switch cubicle, the accident of high-voltage charged body occurs to brush up against outside the person or switch cubicle, there is feature flexible, safe and reliable, easy-to-install.
Accompanying drawing explanation
Fig. 1 is that the present invention works as the handcart not structural representation in switch cubicle；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is that the present invention works as handcart and shakes into the top view in switch cubicle.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, dynamic plate 3, baffle plate 4 and limiting plate 6 horizontal positioned from top to bottom successively, dynamic plate 3 is the handle structure of right-hand member processus aboralis, the processus aboralis part of dynamic plate 3 right-hand member has longitudinal long slot bore I 2, limiting plate 6 is fixed on cabinet, limiting plate 6 centre position has horizontal long slot bore II 8, baffle plate 4 has circular hole on centre position, bolt I 5 sequentially passes through long slot bore I 2 from top to bottom, long slot bore II 8 and circular hole, bolt II 7 sequentially passes through the right front ends of dynamic plate 3 and the right front ends of limiting plate 6 from top to bottom, plate 3 and limiting plate 6 is made to be hinged, and dynamic plate 3 can bolt II 7 be that axle rotates, the rear end of spring 10 is fixed on the left back end of limiting plate 6, its front end is fixed on the rear end of dynamic plate 3 processus aboralis part.
When circuit breaker cart is not in switch cubicle, the angle that dynamic plate 3 and handcart shake into direction is 60 °, the left side of baffle plate 4 is stuck in upper plate 1 and the opening position of lower plate 9, baffle plate 4 is made to engage with upper plate 1 and lower plate 9, stoping upper plate 1 and lower plate 9 transmission, then stop valve to be subjected to displacement due to external force or self gravitation effect, now bolt I 5 is positioned at the rear end of long slot bore I 2, bolt I 5 is positioned at the left end of long slot bore II 8 simultaneously, and spring 10 is in nature compressive state.
As shown in Figure 3, squeeze pressure dynamic plate 3 to rotate clockwise when handcart is moved to the left, baffle plate 6 is made to move right, spring 10 is upheld gradually, when dynamic plate 3 shake with handcart into direction parallel time (now handcart has been pushed into), baffle plate 6 separates with upper plate 1, lower plate 9, and now valve mechanism can transmission, valve can be opened, and bolt I 5 is positioned at the right-hand member of long slot bore II 8 simultaneously.
