Abstract
The utility model provides a valve blocking mechanism including a blocking drive board, a blocking board, a guide post, a tension spring, a rotary shaft and a locking post. The locking post is installed on a side board of the cabinet body of a switch cabinet fixedly. The blocking drive board is installed on a valve main welding support in a rotary manner through the rotary shaft. Two ends of the blocking board are both installed on the blocking drive board fixedly. The middle part of the blocking board is provided with an arc-shaped gap use for fitting the locking post. The guide post is installed on the back side of the blocking drive board fixedly and can be inserted a guide groove arranged in the valve main welding support in a sliding manner. One end of the tension spring is fixed on the valve main welding support while the other end is fixed on the guide post. The valve blocking mechanism provided by the utility model has beneficial effects that the valve blocking mechanism is simple in structure and high in reliability. By arranging the blocking mechanism on a valve mechanism externally, a safety problem caused by blocking of the valve mechanism and a valve blocking board in traditional art is solved and possibility of faulty operation is reduced.
Description
Technical field
The utility model belongs to middle pressure power transmission and distribution field, is specifically related to a kind of valve blocking mechanism of withdraw-type switch cabinet.
Background technology
Valve mechanism is the safety device being arranged in switch cubicle between portable function handcart and main circuit contact box, and its structure generally comprises the valve plate up and down that is positioned at contact box the place ahead, and valve plate drives link rod, handcart compressive-shear knife plate etc.
When function handcart that can withdraw-type is during in normal operating condition, main circuit is connected.When needs power-off or while keeping in repair, functional part disengaging is connected with main circuit contact box, retreat to outside test position or switch cubicle, the former upper and lower valve of opening of valve mechanism is closed automatically, main circuit contact box sealing isolation by charged, enters the safety of carrying out the maintenance personal of maintenance work in cabinet to ensure.
Current switch cubicle, mostly at function handcart, shift out outside cabinet or during interruption maintenance, all exist manual push-and-pull valve still can open valve plate, once staff, occurring similar misoperation, easily encounter still charged main circuit contact box, cause great electric shock accidents.
Utility model content
The purpose of this utility model is to provide a kind of valve blocking mechanism, and valve blocking mechanism is arranged between valve mechanism and side cabinet, and with after reaching function handcart and leaving, valve automatic blocking, strengthens the protection to personal safety.
The utility model is achieved by the following technical solution:
A blocking mechanism, is characterized in that, comprises latch actuation plate, latch plate, lead, extension spring, rotating shaft and stops lock, and described only lock is fixedly mounted on the side cabinet of switch cubicle; Described latch actuation plate is arranged on the main weldering support of valve by rotating shaft is rotating; The two ends of described latch plate are all fixedly mounted on latch actuation plate, and the mid portion of latch plate is provided with one for the arc notch with only lock coordinates; Described lead is fixedly mounted on the back side of latch actuation plate, and slidably inserts in the guide groove arranging on the main weldering support of valve; One end of described extension spring is fixed on the main weldering support of valve, and the other end is fixed on lead.
Further setting of the present utility model is, the two ends of described latch plate are arranged on latch actuation plate by two reinforced shafts respectively.
Further setting of the present utility model is, described extension spring is fixed on the main weldering support of valve by extension spring post.
The beneficial effects of the utility model are: simple in structure, reliability is high, by setting up blocking mechanism on valve mechanism, thereby have solved the safety problem of bringing because of locking between valve mechanism and valve baffle plate in conventional art, have reduced the possibility of misoperation.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Fig. 1-6, the utility model provides a kind of valve blocking mechanism, comprises latch actuation plate 1, latch plate 2, lead 5, extension spring 6, rotating shaft 7 and stops lock 11.On the main weldering support 13 of valve that this valve blocking mechanism is installed on valve mechanism, form one with valve mechanism drive part, only lock 11 is all loaded on the same bearing-surface of switch cubicle side plate with valve mechanism rotating spindle 12, and install minute left and right sides, release simultaneously, valve just can be opened.
Wherein, described valve mechanism comprises the main weldering support 13 of valve, valve pressing plate 8, and valve pull bar 9 and valve mechanism rotating spindle 12 etc., this is the state of the art, does not repeat them here.
Described latch actuation plate 1 is arranged on the main weldering support 13 of valve by rotating shaft 7 is rotating; The two ends of described latch plate 2 are all fixedly mounted on latch actuation plate 1 by two reinforced shafts 3, and the mid portion of latch plate 2 is provided with one for the arc notch 14 with only lock 11 coordinates; Described lead 5 is fixedly mounted on the back side of latch actuation plate 1, and slidably inserts in the guide groove 15 arranging on the main weldering support 13 of valve; One end of described extension spring 6 is fixed on the main weldering support 13 of valve by extension spring post 4, and the other end is fixed on lead 5.
Automatic blocking process shown in Fig. 1 is: function handcart is moved in the process outside cabinet, slowly depart from latch actuation plate 1, latch plate 2, under the pulling force effect of extension spring 6, be take rotating shaft 7 as the center of circle, move upward clockwise, along the guide groove 15 of lead 5, move to top dead-centre.Only lock 11 is stuck in the arc notch 14 in latch plate 2, and latch plate 2 forms automatic blocking states with stopping lock 11, and upper and lower valve is locked.
Releasing process is as shown in Figure 2: function handcart enters in cabinet to reaching in the process of test position from cabinet, first function handcart driving wheel 10 will touch latch actuation plate 1, function handcart driving wheel 10 is to previous crops horizontal motion, latch actuation plate 1, latch plate 2 are done as a whole, be subject to after External Force Acting, take rotating shaft 7 as the center of circle, and the downward guide groove 15 along lead 5 moves counterclockwise.At function handcart, advance after a segment distance, latch plate 2 and only lock 11 disengagings, valve blocking mechanism is removed, and handcart arrives test position.After this, because function handcart driving wheel 10 1 vertical compressions 1 latch actuation wheel motion, until be transitioned into valve pressing plate 8, valve locking is all the time in released state.
When handcart enters service position state as shown in Figure 3, the final motion state of valve blocking mechanism.
More than described basic principle of the present utility model and principal character, its core is the ingenious release track principle contrary with movement locus of having utilized, and has improved the reliability of locking, and apparatus structure is simple simultaneously.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and departed from scope of the present utility model.All so apparent modifications of the technical staff to described field, within being included in the scope of this claim.
