[0033] In order to make the technical problems, technical solutions and beneficial effects of the embodiments of the utility model clearer, the following will make a brief introduction to the drawings needed to be used in the embodiments or prior art description. Obviously, the drawings in the following description are only some embodiments of the utility model, and other drawings can be obtained by those skilled in the art without creative labor.
[0034] In the prior art, the switch assembly 5 generally comprises a switch panel 51, a switch knob 52 and electrical components, the switch panel 51 is fixed, and the switch assembly 5 is closed and opened by pulling the switch knob 52. In order to facilitate operation, the switch knob 52 is generally in an exposed state without position limitation, and there is a risk of being mistakenly touched by unauthorized personnel.
[0035] In order to solve the above problems, please refer to Figures 1 to 3 The switch anti-mis-touch assembly for nuclear power plants comprises a shielding structure 1, a sliding structure 2 and a locking piece 3. The shielding structure 1 is arranged on the outer side of the switch panel 51; the shielding structure 1 has a clearance 11 for avoiding the switch knob 52, and the clearance 11 has a diameter greater than the moving stroke of the switch knob 52; the sliding structure 2 is arranged between the shielding structure 1 and the switch panel 51; and the locking piece 3 is arranged on the sliding structure 2 and used for locking the sliding structure 2.
[0036] The sliding structure 2 has a first position and a second position. In the first position, the locking piece 3 is in a locked state, and the sliding structure 2 abuts against the switch knob 52 along the pulling direction of the switch knob 52; in the second position, the locking piece 3 is in an unlocked state, and the sliding structure 2 is separated from the switch knob 52.
[0037] The shielding structure 1 is arranged on the outer side of the switch panel 51, and the shielding structure 1 is fixed and in a fixed state. It should be noted that the above-mentioned "inner" and "outer" are based on the installation direction of the switch panel 51 as a reference, and the side of the switch panel 51 facing the installation base is "inner", and the side away from the installation base is "outer".
[0038] The shielding structure 1 has an outer dimension greater than that of the switch panel 51, so that the shielding structure 1 can be completely covered on the switch panel 51, and only the switch knob 52 needs to be exposed.
[0039] In addition, the shielding structure 1 is further provided with the clearance 11, and the clearance 11 has a diameter greater than the moving stroke of the switch knob 52, so that the switch knob 52 can be normally pulled without interference with the shielding structure 1.
[0040] The sliding structure 2 is slidingly arranged between the switch panel 51 and the shielding structure 1. The sliding structure 2 is controlled to slide by an operator, and can be electrically sliding or manually sliding. The sliding direction of the sliding structure 2 can be any direction parallel to the plane where the switch panel 51 is located, and since the sliding structure 2 is limited between the switch panel 51 and the shielding structure 1, there is no problem of sliding disengagement.
[0041] It should be noted that although the sliding direction of the sliding structure 2 is arbitrary, the sliding structure 2 has a preset sliding track. When in the first position, the sliding structure 2 abuts against the switch knob 52, and the sliding structure 2 limits the switch knob 52, so that the switch knob 52 is blocked and cannot be arbitrarily actuated. When in the second position, the sliding structure 2 is separated from the switch knob 52, and the operator can actuate the switch knob 52. The first position and the second position described above are fixed positions, and in particular for the second position, the sliding structure 2 can stably be in the second position and not be arbitrarily moved.
[0042] The switch knob 52 has a normally open state and a normally closed state. The normally open state corresponds to the first position, and the normally closed state corresponds to the second position. Alternatively, the normally open state corresponds to the second position, and the normally open state corresponds to the first position. The specific correspondence relationship is determined according to the application requirements of the switch assembly 5. In addition, the switch knob 52 can be linearly actuated or rotationally actuated, and the specific actuation form is determined according to the use requirements.
[0043] The locking member 3 is used to lock the sliding structure 2, so that the sliding structure 2 cannot be arbitrarily moved when in the first position, and remains in a stable state. When the locking member 3 is unlocked, the sliding structure 2 can be moved under the action of an external force, thereby achieving switching between the first position and the second position.
[0044] The locking member 3 can adopt a mechanical locking structure, or use an existing lock, or use a commonly used locking member in the prior art. The embodiment does not limit the specific form of the locking member 3, as long as it can be locked and unlocked, and can lock the sliding structure 2 in the first position. The locking member 3 can be directly locked on the shielding structure 1, or can be locked on the switch panel 51, or can be hidden and locked on the periphery of the switch panel 51. Preferably, the locking member 3 is locked on the periphery of the switch panel 51, and the locked position can be hidden and not easily found by non-operators.
[0045] In actual application, the operator uses the locking member 3 to lock the sliding structure 2, so that the sliding structure 2 is in the first position and the switch knob 52 cannot be actuated, thereby avoiding unauthorized personnel from causing the switch assembly 5 to be tripped due to accidental touch of the switch knob 52. When it is actually necessary to actuate the switch knob 52, the operator releases the locking of the locking member 3, and slides the sliding structure 2, so that the sliding structure 2 loses the abutting limit, and the switch knob 52 can be freely actuated.
[0046] The switch anti-misoperation assembly for nuclear power station has the advantages that the sliding structure 2 is arranged between the shielding structure 1 and the switch panel 51, the locking piece 3 is arranged on the sliding structure 2, the locking piece 3 is locked when the sliding structure 2 is in the first position, the stable abutment of the sliding structure 2 and the switch knob 52 is formed, the switch knob 52 is prevented from being actuated under the action of other external forces, the switch assembly 5 is prevented from being tripped due to the misoperation of the switch knob 52 by non-operating personnel, and the safety hazard is eliminated.
[0047] In some embodiments, the structure between the shielding structure 1 and the sliding structure 2 can be as shown in Figure 1 、 Figure 2 and Figure 3 , referring to Figure 1 、 Figure 2 and Figure 3 , the sliding rail 12 is arranged on the shielding structure 1, and the sliding block 22 is connected to the sliding structure 2; or the sliding rail 12 is arranged on the sliding structure 2, and the sliding block 22 is connected to the shielding structure 1; the sliding block 22 and the sliding rail 12 are in sliding cooperation, so that the sliding structure 2 is switched between the first position and the second position.
[0048] The sliding block 22 and the sliding rail 12 are in sliding cooperation between the shielding structure 1 and the sliding structure 2, the sliding rail 12 plays a guiding role, the sliding of the sliding structure 2 along the preset path is ensured, and the sliding block 22 is located in the sliding rail 12, so that the sliding structure 2 is prevented from being separated from the shielding structure 1 due to excessive force when sliding.
[0049] In addition, the sliding block 22 and the sliding rail 12 are in sliding friction, if the sliding rail 12 extends and is arranged in the upward and downward directions, when the sliding block 22 is located at the top of the sliding rail 12, under the action of gravity, due to the friction between the sliding block 22 and the sliding rail 12, the sliding structure 2 is also prevented from falling rapidly and hitting the switch knob 52.
[0050] It should be noted that the sliding rail 12 can be arranged on the shielding structure 1 or the sliding structure 2, correspondingly, the sliding block 22 can be arranged on the sliding structure 2 or the shielding structure 1, the specific fixed position of the sliding rail 12 and the sliding block 22 is not limited in the embodiment, as long as the sliding block 22 and the sliding rail 12 are fixed between the sliding structure 2 and the shielding structure 1 and in sliding cooperation.
[0051] Preferably, on the basis of the above embodiment, the sliding rail 12 is arranged on the shielding structure 1, the sliding block 22 is arranged on the sliding structure 2, and one end of the sliding block 22 penetrates through the shielding structure 1 and is exposed outside the shielding structure 1.
[0052] Since the sliding structure 2 is a sliding member, the sliding block 22 is arranged on the sliding structure 2, so that the sliding block 22 moves along with the sliding structure 2, to further ensure the sliding stability, and the design and manufacture are facilitated.
[0053] In addition, the slider 22 and the slide rail 12 not only play the role of sliding guide limiter for the sliding structure 2, but also one end of the slider 22 extends out of the slide rail 12 to assist in applying force. When the operator slides the sliding structure 2, the operator can hold the slider 22 to apply force, thereby facilitating the operation.
[0054] Preferably, the slide rails 12 extend horizontally. The shielding structure 1 is provided with two sets of slide rails 12, and correspondingly, the sliding structure 2 is provided with two sets of sliders 22. When the sliders 22 slide to one end of the slide rails 12, the sliding structure 2 is in a first position. When the sliders 22 slide to the other end of the slide rails 12, the sliding structure 2 is in a second position.
[0055] In some embodiments, the sliding structure 2 may be configured as follows: Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 The sliding structure 2 is a plate-shaped structure, and a notch 23 is provided on the sliding structure 2. When in the second position, the notch 23 corresponds to the switch button 52 along the toggle direction.
[0056] Since the sliding structure 2 is slidably arranged between the shielding structure 1 and the switch panel 51, the sliding structure 2 is a plate-like structure, which can save its occupied space and reduce the overall thickness of the nuclear power plant switch anti-accidental touch assembly, and the plate-like structure is easy to process, manufacture and assemble.
[0057] The sliding structure 2 is provided with a notch 23 , which is used to avoid the switch button 52 so that the switch button 52 can be smoothly toggled when the sliding structure 2 is in the second position; on the other hand, it can also reduce the overall weight of the sliding structure 2 .
[0058] In some embodiments, the sliding structure 2 can also be used as follows Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 The sliding structure 2 has a locking portion 21 , which extends to the outside of the shielding structure 1 ; the locking member 3 is arranged on the locking portion 21 .
[0059] The locking portion 21 is mainly used to set the locking member 3, so the locking member 3 is also located outside the shielding structure 1, which increases the manual operation space. When locking and unlocking the locking member 3, there is no need to perform actions at the avoidance opening 11.
[0060] The locking member 3 can be directly locked to the shielding structure 1 or locked to the switch panel 51. Of course, the locking member 3 can also be shielded and locked to the outer periphery of the switch panel 51. If the switch panel 51 is fixed to the door panel of a nuclear power plant cabinet, the locking member 3 can also be locked to the door panel of the nuclear power plant cabinet.
[0061] In some embodiments, the shielding structure 1 may be configured as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The shielding structure 1 is a cover structure with one side open, and the avoidance opening 11 is provided on a side panel opposite to the opening side.
[0062] The shielding structure 1 is a cover structure, which is arranged on the outside of the switch panel 51. It has a simple structure and is easy to process and manufacture and assemble with the switch panel 51. It is also thin and occupies little space, which can further reduce the overall thickness of the switch anti-accidental touch assembly for nuclear power plants.
[0063] In some embodiments, the shielding structure 1 may be configured as follows: Figure 2 The structure shown, see Figure 2 A flange 13 is provided on the wall of the avoidance opening 11 , and the flange 13 is folded toward the inside of the shielding structure 1 .
[0064] The shielding structure 1 is generally a sheet metal part, and the avoidance opening 11 is cut out. Then, the cut edge (i.e., the wall of the avoidance opening 11) may have burrs or sharp edges. When the operator turns the switch button 52, there is a risk of accidentally touching the wall of the avoidance opening 11 and being scratched.
[0065] In order to avoid the above problems, a flange 13 is provided at the mouth wall of the avoidance opening 11. The flange 13 is integrally formed with the shielding structure 1 and is folded toward the inside of the shielding structure 1 to form an arc transition. There are no burrs or sharp edges on the flange 13. Even if the operator touches the flange 13, there is no risk of being cut.
[0066] In some embodiments, the locking member 3 may be configured as follows: Figure 1 The structure shown, see Figure 1 The locking member 3 is a captive screw.
[0067] The captive screw is press-riveted or expansion-riveted on the locking portion 21. The captive screw generally comprises a screw, a hand-tightening sleeve, a pressure riveting sleeve and a spring. The captive screw used in this embodiment is a common structure in the prior art, and its specific structure is not repeated here.
[0068] The captive screw can be directly fixed on the locking portion 21 to avoid loss. Moreover, the captive screw does not require tools when locking or unlocking, making operation convenient.
[0069] Based on the same inventive concept, an embodiment of the present application also provides a cabinet door panel for a nuclear power plant, comprising a door panel body 4, a switch assembly 5 and the above-mentioned switch anti-accidental touch assembly for a nuclear power plant.
[0070] The switch assembly 5 is arranged on the door plate body 4; the switch assembly 5 comprises a switch panel 51 and a switch knob 52; and the shielding structure 1 of the switch anti-misoperation assembly for nuclear power plants is fixedly arranged on the door plate body 4.
[0071] In the prior art, the switch assembly 5 generally comprises the switch panel 51 and the switch knob 52; the switch panel 51 is fixed on the door plate body 4; and the switch assembly 5 is closed and opened by means of the switch knob 52. In order to facilitate human operation, the switch knob 52 is generally in an exposed state and has no position limit, and thus has a risk of being misoperated by unauthorized personnel.
[0072] Preferably, in order to improve the fixing strength and stability of the shielding structure 1, the shielding structure 1 is fixed on the door plate body 4 by means of a stud.
[0073] The cabinet door plate for nuclear power plants provided by the utility model is characterized in that the switch anti-misoperation assembly for nuclear power plants is arranged outside the switch panel 51; the sliding structure 2 is arranged between the switch panel 51 and the shielding structure 1 and can be locked by the locking piece 3 in the first position, so that the sliding structure 2 and the switch knob 52 form stable abutment, the switch knob 52 is limited from being actuated under the action of other external forces, and thus the switch assembly 5 is prevented from being opened due to the misoperation of the switch knob 52 by non-operating personnel, and the safety hazard is eliminated.
[0074] In some embodiments, the side edge of the door plate body 4 is provided with a stop edge 41; the sliding structure 2 is provided with a locking portion 21; the locking portion 21 extends to the outside of the shielding structure 1; and the locking piece 3 is arranged on the locking portion 21; and in the first position, the locking piece 3 is locked with the stop edge 41.
[0075] The locking portion 21 is mainly used for arranging the locking piece 3, and thus the locking piece 3 is also located at the periphery of the shielding structure 1; when the locking piece 3 is locked and unlocked, no action needs to be performed at the avoiding opening 11, and the human operation space is increased. Moreover, the stop edge 41 is located at the side edge of the door plate body 4 and is folded forward or backward; the locking piece 3 is locked on the stop edge 41 and can also be shielded by the stop edge 41 and is not easy to be found, and thus the misoperation of non-operating personnel is further avoided.
[0076] The above merely describes preferred embodiments of the utility model and is not intended to limit the utility model; any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
