Description

Technical Field

[0001] The utility model relates to the technical field of power plants and transformer substations, in particular to an adjusting locking mechanism and a detection system. Background Art

[0002] In power plants and substations, the mode function handle refers to a functional handle that realizes mode switching by switching the handle position. It consists of two or more node states inside, and the switching of different functions is realized by switching between nodes. It has a wide range of uses, such as realizing the state switching of electrical switches with local and remote operation functions, or realizing the switching of unlocking and interlocking functions of related systems and electrical switches, or realizing the switching of remote and local functions of systems such as hydropower station excitation and speed regulators, or realizing the switching of electric pumps, motors, air compressors, etc. with automatic, cut-off, and local operation mode functions.

[0003] Currently, there are two mainstream mode handles. One is the mode function handle without anti-error function. It is simple to operate and can switch the mode function at the specified position by directly rotating the handle. However, it has no anti-error function and is generally only used for switching unimportant mode functions, such as switching of electric pumps, motors, air compressors, etc. with automatic, cut-off, and local operation mode functions; the other is the mode function handle with anti-error function. Its operation requires first releasing the anti-error function and then directly rotating the handle at the specified position to switch the mode function. It is generally used for switching more important mode functions, such as unlocking an electrical switch, switching an interlocking function, or switching remote and local functions of important systems such as excitation and speed regulators in hydropower stations.

[0004] At present, the mode function handles with anti-error function are unlocked by inserting relevant keys. Different mode function handles are unlocked by different keys, and the keys are generally stored together for management. At present, there are the following operational deficiencies for such mode function handles: 1. If a person finds that the equipment or system fails during the on-site inspection and needs to switch the mode urgently, he needs to return to the place where the unlocking key is stored and take the key to return to the site to switch the mode, which increases the time for emergency processing and is not conducive to emergency processing or accident processing; 2. If it is necessary to operate, it is found that the unlocking key is broken or lost for some reason, or the key is broken in the keyhole due to excessive force during the insertion of the unlocking key, which is not conducive to subsequent operations and affects the quality of work; 3. The anti-error keys of some mode function handles with anti-error function are the same unlocking keys in the same system of the whole factory, which are not independent and have no function to prevent wrong interval operation; 4. If there are many mode function handles with anti-error function, the complexity of unlocking key management is increased. Utility Model Content

[0049] Specifically, the thread groove 203a-1 is rotatably connected to the thread column 201, and when the thread column 201 rotates to a fixed value, it is aligned with the thread groove 203a-1. A locking member 203b is provided on the switching member 203a, and a hole is provided in the middle of the locking member 203b so that the first connecting rod 102a can pass through. When the first connecting rod 102a passes through the hole in the middle of the locking member 203b, the movable member 202b enters the interior of the locking member 203b.

At this time, the fixed ring 202b-3 contacts the inclined surface of the inclined block 203b-4 and causes the inclined block 203b-4 to drive the second connecting rod 203b-3 to compress the second telescopic spring 203b-6 and move it into the locking shell 203b-2. When the fixed ring 202b-3 passes through the inclined block 203b-4, the plane on the inclined block 203b-4 contacts the plane of the fixed ring 202b-3 and cannot be disassembled to form a locking state.

[0051] During disassembly, the staff needs to unlock the first adjusting disk 103c before the first connecting rod 102a can drive the protrusion 103a into the groove 103c-2. At this time, the movable column 202b-1 is displaced into the locking piece 203b again, and the movable column 202b-1 is pressed again to make the movable ring 202b-2 on the movable column 202b-1 pass through the inclined block 203b-4. At this time, the movable column 202b-1 is subjected to the pulling force of the first telescopic spring 202a-3 to insert the side of the movable ring 202b-2 close to the fixed ring 202b-3 into the interior of the fixed ring 202b-3. At this time, as the arc surface of the movable ring 202b-2 close to the inclined block 203b-4 side is disengaged from the locking piece 203b, the threaded column 201 is rotated to make the threaded column 201 disengage from the threaded groove 203a-1 to form disassembly.
