[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figures 1 to 2 , Figures 5-11 As shown, the present invention provides a photovoltaic power generation transformer anti-misoperation isolation lock, comprising two locking mechanisms 1.

[0046] Two locking mechanisms 1 are respectively provided on the rotating shaft 5 of the high-voltage switch and the grounding switch. The locking mechanism 1 has a locked state and an unlocked state. The locking mechanism 1 includes:

[0047] The first locking sleeve 11 is provided with a fitting part 111 and a limiting hole 112. The first locking sleeve 11 is fitted onto the knife switch rotating shaft 5 through the fitting part 111.

[0048] The second lock sleeve 12 is fitted onto the first lock sleeve 11;

[0049] Ball bearing 13 is disposed on the limiting hole 112;

[0050] When the locking mechanism 1 is switched to the locked state, the ball 13 is squeezed by the second locking sleeve 12 and squeezes the knife switch rotating shaft 5 through the limiting hole 112 to lock the first locking sleeve 11 on the knife switch rotating shaft 5.

[0051] When the locking mechanism 1 is switched to the unlocked state, the second locking sleeve 12 moves relative to the first locking sleeve 11, releasing the compression lock on the ball 13, and the ball 13 disengages from the knife switch rotating shaft 5, so that the first locking sleeve 11 and the knife switch rotating shaft 5 can be separated from each other.

[0052] In this embodiment, two locking mechanisms 1 are provided, corresponding to the rotating shafts 5 of the high-voltage switch and the grounding switch on the operating area 61 of the transformer substation 6, respectively. This allows for locking and shielding of the rotating shafts 5 of the high-voltage switch and the grounding switch after safety electrical isolation measures are implemented, thereby improving operational safety and preventing misoperation, as well as personnel injury and equipment damage.

[0053] Specifically, when it is necessary to lock the knife switch rotating shaft 5, the locking mechanism 1 is first switched to the unlocked state so that the first locking sleeve 11 is fitted onto the knife switch rotating shaft 5. Then, by moving the second locking sleeve 12, the ball 13 is squeezed through the second locking sleeve 12. At this time, the ball 13 is squeezed into the limiting hole 112 and squeezed toward the knife switch rotating shaft 5, thereby locking the first locking sleeve 11 onto the knife switch rotating shaft 5 and preventing personnel from operating the knife switch rotating shaft 5.

[0054] When it is necessary to unlock the knife switch rotating shaft 5 for operation, the second locking sleeve 12 is moved, thereby releasing the compression lock on the ball bearing 13. At this time, without external force, the ball bearing 13 disengages from the knife switch rotating shaft 5, allowing the first locking sleeve 11 to separate from the knife switch rotating shaft 5. The quick locking and unlocking of the knife switch rotating shaft 5 is achieved through the first locking sleeve 11, the second locking sleeve 12, and the ball bearing 13, making it safer, more efficient, and more reliable.

[0055] like Figures 8-11 As shown, in one embodiment, the second locking sleeve 12 is provided with a first limiting part 121 and an active area 122;

[0056] When the locking mechanism 1 is in the locked state, the second locking sleeve 12 squeezes the ball 13 through the first limiting part 121, so that the ball 13 squeezes the knife switch rotating shaft 5.

[0057] When the locking mechanism 1 is switched to the unlocked state, the first limiting part 121 moves away from the ball 13 so that the ball 13 disengages from the knife switch rotating shaft 5 and can move between the limiting hole 112 and the active area 122.

[0058] In this embodiment, by setting a first limiting part 121 on the second locking sleeve 12, the ball 13 is quickly squeezed to achieve a fast locking effect. By setting an active area 122, the active space of the ball 13 is increased when unlocking is required, so that the ball 13 is disengaged from the knife gate rotating shaft 5, thereby facilitating the removal of the locking mechanism 1 from the knife gate rotating shaft 5.

[0059] like Figures 8-11 As shown, in one embodiment, the first locking sleeve 11 is further provided with a limiting groove and a second limiting part 114. An elastic retaining ring 113 is provided on the limiting groove, and a limiting area is formed between the elastic retaining ring 113 and the second limiting part 114.

[0060] The first limiting part 121 is located within the limiting area, which is used to prevent the first locking sleeve 11 from separating from the second locking sleeve 12.

[0061] In this embodiment, a limiting groove is provided on the first locking sleeve 11 to facilitate the installation of the elastic retaining ring 113, and a limiting part 114 is provided to cooperate with the elastic retaining ring 113 to form a limiting area that limits the first limiting part 121 of the second locking sleeve 12, thereby preventing the second locking sleeve 12 from disengaging from the first locking sleeve 11 when it moves, thus ensuring operational stability.

[0062] like Figures 1 to 2 , Figures 5-11 As shown, in one embodiment, the knife switch rotating shaft 5 has a shaft hole;

[0063] The locking mechanism 1 also includes a positioning pin 14, and the first locking sleeve 11 is connected to the positioning pin 14 through a bearing 15; wherein, the positioning pin 14 is used to be inserted into the shaft hole of the knife switch rotating shaft 5.

[0064] In this embodiment, a positioning pin 14 corresponding to the shaft hole is provided, and the positioning pin 14 is connected to the first locking sleeve 11 through a bearing 15, so as to facilitate the loading and unloading of the locking mechanism 1. It should be noted that the outer surface of the positioning pin 14 does not contact the inner surface of the shaft hole to avoid obstructing the operation of the locking mechanism 1.

[0065] like Figures 1 to 2 , Figures 5-11 As shown, in one embodiment, a pressing member 2 is also included. The pressing member 2 has connecting parts at both ends, and the pressing member 2 is connected to the second locking sleeves 12 of the two locking mechanisms 1 through the connecting parts at both ends.

[0066] In this embodiment, the two locking mechanisms 1 are connected by the pressing member 2, thereby improving the ease of operation.

[0067] The connecting part is provided with a through hole, and the positioning pins 14 of the two locking mechanisms 1 are connected to the pull rod 3 through the through hole. The diameter of the through hole is larger than the outer diameter of the upper part of the first locking sleeve 11 to avoid interference with the first locking sleeve 11 when the locking mechanism 1 is working.

[0068] like Figures 8-11 As shown, in one embodiment, the second lock sleeve 12 has a locked position and an unlocked position;

[0069] The locking mechanism 1 also includes a first elastic element 16, which is used to drive the second locking sleeve 12 to move to the locking position so that the locking mechanism 1 switches to the locking state;

[0070] The pressing element 2 is used to drive the second locking sleeve 12 to move to the unlocked position, so that the locking mechanism 1 switches to the unlocked state.

[0071] In this embodiment, since the second locking sleeve 12 is connected to the pressing member 2, the operator can manually drive the pressing member 2 to move relative to the first locking sleeve 11, thereby moving the second locking sleeve 12 to the unlocked position and switching the locking mechanism 1 to the unlocked state.

[0072] It should be noted that when the locking mechanism 1 is switched to the unlocked state, the first elastic element 16 is compressed. After the operator releases the force on the pressing element 2, the first elastic element 16 is reset, thereby driving the second locking sleeve 12 to move to the locking position, so that the locking mechanism 1 is switched to the locking state.

[0073] like Figures 8-11 As shown, in one embodiment, the first elastic element 16 includes a spring sleeved on the first locking sleeve 11, and the first elastic element 16 is located between the first limiting portion 121 of the second locking sleeve 12 and the second limiting portion 114 of the first locking sleeve 11.

[0074] In this embodiment, the first elastic element 16 includes a spring. By sleeved on the first locking sleeve 11 and located between the first limiting part 121 of the second locking sleeve 12 and the second limiting part 114 of the first locking sleeve 11, the first limiting part 121 is driven to move relative to the second limiting part 114, thereby driving the second locking sleeve 12 to move to the locking position, thus ensuring operational stability.

[0075] It should be noted that after the first locking sleeve 11 is engaged with the knife switch rotating shaft 5 through the fitting part 111, the first locking sleeve 11 can no longer move in the direction of the knife switch rotating shaft 5. It can only be removed from the knife switch rotating shaft 5 when the locking mechanism 1 is in the unlocked state. In other words, the operator can directly drive the pressing part 2 to move in the direction of the knife switch rotating shaft 5, so that the second locking sleeve 12 can move relative to the first locking sleeve 11, so that the second locking sleeve 12 moves to the unlocked position, thereby efficiently unlocking the locking mechanism 1.

[0076] It should be understood that there is a gap between the pressing part 2 and the surface of the operating area 61 of the transformer substation 6 so that the pressing part 2 can move relative to the first locking sleeve 11 and the knife switch rotating shaft 5, thereby enabling the locking mechanism 1 to be placed on the knife switch rotating shaft 5 and to be easily removed from the knife switch rotating shaft 5.

[0077] If necessary, a second elastic element can be provided between the pressing element 2 and the operating area 61 to ensure the locking effect on the knife switch rotating shaft 5. The second elastic element includes a spring.

[0078] like Figures 1 to 2 , Figures 5-11 As shown, in one embodiment, a pull rod 3 is also included, with both ends of the pull rod 3 connected to the positioning pins 14 of the two locking mechanisms 1 respectively.

[0079] In this embodiment, by setting a pull rod 3 and connecting its two ends to the positioning pins 14 of the two locking mechanisms 1 respectively, the overall stability and operability are improved.

[0080] It should be noted that the positioning pin 14 and the pull rod 3 can be threaded or fixedly connected. Specifically, when it is threaded, the end of the positioning pin 14 is provided with a threaded part, and both ends of the pull rod 3 are provided with threaded holes. The positioning pin 14 is installed in the threaded holes of the pull rod 3 through the threaded part. It should be understood that since the positioning pin 14 is connected to the first locking sleeve 11 through the bearing 15, the positioning pin 14 can rotate relative to the first locking sleeve 11, thereby achieving a detachable connection with the pull rod 3.

[0081] In one embodiment, when the locking mechanism 1 switches to the locked state, the pull rod 3 and the pressing member 2 move closer to each other.

[0082] When the locking mechanism 1 is switched to the unlocked state, the lever 3 and the pressing part 2 move away from each other.

[0083] In this embodiment, since the pull rod 3 is connected to the positioning pin 14, and the positioning pin 14 is connected to the first locking sleeve 11 through the bearing 15, and the pressing member 2 is connected to the second locking sleeve 12, it is ensured that by using the pull rod 3 and the pressing member 2 together, the operator can quickly switch between the unlocking state and the locking state of the locking mechanism 1.

[0084] Specifically, when it is necessary to switch the locking mechanism 1 to the unlocked state, simply move the pull rod 3 and the pressing member 2 away from each other. That is, by moving the pull rod 3 and the pressing member 2 in opposite directions, the pressing member 2 drives the second locking sleeve 12 to move relative to the first locking sleeve 11. At this time, the pull rod 3 provides a force to the first locking sleeve 11 in the opposite direction of the movement of the second locking sleeve 12 through the positioning pin 14 and the bearing 15, thereby ensuring that the second locking sleeve 12 moves to the unlocked position, thus switching the locking mechanism 1 to the unlocked state. After the operator cancels the force applied to the locking mechanism 1, the first elastic member 16 resets, driving the second locking sleeve 12 to the locked position, thereby switching the locking mechanism 1 to the locked state.

[0085] Meanwhile, the pressing element 2 and the pull rod 3 further prevent misoperation of one or both knife switch rotating shafts 5, ensuring the working stability and safety of this isolation lock.

[0086] like Figures 1 to 2 , Figures 5-7 As shown, in one embodiment, it also includes a protective shell 4, which is provided with a receiving cavity 41 and a first buckle 42, with the first buckle 42 disposed inside the receiving cavity 41.

[0087] The pressing part 2 is provided with a second buckle 21, and the first buckle 42 is engaged with the second buckle 21.

[0088] When the first buckle 42 and the second buckle 21 are engaged and connected, and the locking mechanism 1 is locked on the knife switch rotating shaft 5, the protective shell 4 covers the knife switch rotating shaft 5 of the high voltage knife switch and the grounding knife switch, and the pressing part 2, the pull rod 3 and the two locking mechanisms 1 are located in the accommodating cavity 41.

[0089] In this embodiment, please refer to Figures 3-4 Since the rotating shafts 5 of the high-voltage disconnect switch and the grounding disconnect switch are installed on the operating area 61 of the transformer substation 6, a protective shell 4 is installed over the operating area 61 of the transformer substation 6 to protect the locking mechanism 1, the pressing element 2, the pull rod 3, and the rotating shaft 5 from dust, thus preventing damage to the equipment. A first latch 42 and a second latch 21 are provided to install the protective shell 4 onto the pressing element 2.

[0090] It should be noted that when the protective shell 4 is connected to the pressing member 2, the protective shell 4 is placed over the operating area 61. At this time, the pressing member 2, the pull rod 3 and the two locking mechanisms 1 are located in the receiving cavity 41 of the protective shell 4. By moving the protective shell 4 toward the locking mechanism 1 (i.e. downward), the first buckle 42 and the second buckle 21 can be engaged and connected, thereby realizing the connection between the protective shell 4 and the pressing member 2. When the protective shell 4 needs to be removed, it is only necessary to move the protective shell 4 upward.
