Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to an anti-loosening mounting mechanism for temperature sensors. Background Technology

[0002] In power systems, the plum blossom contact is an important conductive connection component, and its operating temperature directly reflects the contact state and safety performance, making temperature measurement crucial.

[0003] When the stationary contact is inserted into the Phillips head contact, the bolts connecting the temperature sensor can easily loosen under the tension and vibration of the Phillips head contact, resulting in a gap between the temperature sensor and the Phillips head contact. This gap can lead to consequences such as temperature monitoring failure or data distortion, increased risk of local overheating, mechanical structural safety hazards, and decreased insulation performance. To address these issues, we propose an anti-loosening mounting mechanism for temperature sensors. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-loosening mounting mechanism for a temperature sensor, thereby solving the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: It includes a perforated contact and a steel strip. A temperature sensor is fixedly connected to the middle of the steel strip. Silicone gaskets are fixedly connected to both horizontal sides of the temperature sensor on the steel strip. Rivets are fixedly connected to both ends of the steel strip. Connecting rings are fitted onto both ends of the steel strip via the rivets, and each of the two connecting rings is connected to one end of a tension spring.

[0005] The plum blossom contact is fixedly connected to several central columns, and a spring is sleeved on the central column. An outer ring is fixedly connected to one end of the central column, and an inner ring is fixedly connected to the inner surface of the outer ring.

[0006] Several guide rods are fixedly connected to the surface of the inner ring. A pin is slidably connected to the front side of the guide rod. A wedge block is fixedly connected to the top of the pin. A spring is sleeved on the top of the pin. The spring is located inside the guide rod. The wedge block is slidably connected to the guide rod. A locking rod is fixedly connected to the middle of the pin. The locking rod contacts the outer surface of the guide rod. A connecting rod is fixedly connected to the bottom of the pin.

[0007] An outer ring two is slidably connected to one side of the central column relative to the outer ring one. An inner ring two is fixedly connected to the inner surface of the outer ring two. The inner surface of the inner ring two abuts against the surface of the wedge block. The inner ring two is used to axially limit the steel strip.

[0008] Preferably, an unlocking ring is provided on the inner side of the guide rod, and a guide groove is provided through the surface of the unlocking ring, and the unlocking ring is slidably connected to the slip ring through the guide groove.

[0009] Preferably, the inner surface of the unlocking ring is fixedly connected with inclined rails, the number of inclined rails being adapted to the connecting rods and abutting against their surface, and the inclined rails being arc-shaped.

[0010] Preferably, a slip ring is rotatably connected to the surface of the outer ring two, and a plurality of levers are fixedly connected to the inner surface of the slip ring.

[0011] Preferably, a plurality of blocks are fixedly connected to the front side of the unlocking ring, and the surface of the blocks abuts against the surface of the lever.

[0012] Preferably, an arc ring is fixedly connected to the outer surface of the slip ring, and a spring three is sleeved on the arc ring, with one side of the spring three abutting against the outer ring two.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In this invention, by setting tension springs on both sides of the steel strip, the temperature sensor is prevented from being affected by the tension and vibration of the plum blossom contact, thereby avoiding the formation of gaps between the temperature sensor and the plum blossom contact, and preventing the occurrence of temperature monitoring failure and local overheating.

[0015] 2. In this invention, the outer ring two and the inner ring two are movably set so that the wedge block locks the inner ring two, which facilitates axial positioning of the steel strip and the temperature sensor, and further restricts the position of the temperature sensor to prevent displacement.

[0016] 3. In this invention, the steel strip can be unlocked by rotating the slip ring through the unlocking ring, which facilitates disassembly. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1:

[0026] Please see Figures 1 to 2 The present invention provides a technical solution: including a plum blossom contact 1 and a steel strip 2, a temperature sensor 3 is fixedly connected to the middle of the steel strip 2, silicone pads 4 are fixedly connected to the horizontal sides of the temperature sensor 3 on the steel strip 2, rivets 5 are fixedly connected to both ends of the steel strip 2, and connecting rings 6 are sleeved on both ends of the steel strip 2 through the rivets 5, and one end of a tension spring 7 is connected to each of the two connecting rings 6.

[0027] In this embodiment, the temperature sensor 3 is fixed in the middle of the steel strip 2, and the silicone pads 4 on both sides are attached to the surface of the plum blossom contact 1 during installation, so that the temperature sensor 3 is subjected to more uniform force. The two ends of the steel strip 2 are inserted into the connecting ring 6 through the rivets 5. After the steel strip 2 is attached to the surface of the plum blossom contact 1, a ring structure is formed, and the two ends of the tension spring 7 are connected to the two connecting rings 6.

[0028] Example 2:

[0029] Please see Figures 3 to 5 The present invention provides a technical solution: a plurality of central columns 8 are fixedly connected to the plum blossom contact 1, a spring 9 is sleeved on the central column 8, an outer ring 10 is fixedly connected to one end of the central column 8, and an inner ring 11 is fixedly connected to the inner surface of the outer ring 10.

[0030] Several guide rods 12 are fixedly connected to the surface of the inner ring 11. A plug 13 is slidably connected to the front side of the guide rod 12. A wedge block 14 is fixedly connected to the top of the plug 13. A spring 15 is sleeved on the top of the plug 13. The spring 15 is located inside the guide rod 12. The wedge block 14 is slidably connected to the guide rod 12. A locking rod 16 is fixedly connected to the middle of the plug 13. The locking rod 16 contacts the outer surface of the guide rod 12. A connecting rod 17 is fixedly connected to the bottom of the plug 13.

[0031] An outer ring 18 is slidably connected to the middle column 8 on one side relative to the outer ring 10. An inner ring 19 is fixedly connected to the inner surface of the outer ring 18. The inner surface of the inner ring 19 abuts against the surface of the wedge block 14. The inner ring 19 is used to axially limit the steel strip 2.

[0032] In this embodiment, after the steel strip 2 is installed on the plum blossom contact 1 by the tension spring 7, the outer ring 18 is pushed towards the outer ring 10, so that the outer ring 18 drives the inner ring 19 to slide on the central column 8, and gradually compresses the spring 9. After the outer ring 18 is continuously pushed, the inner surface of the inner ring 19 contacts the top surface of the wedge block 14 and presses the wedge block 14 inward, so that the wedge block 14 compresses the spring 15. After the inner ring 19 passes the wedge block 14, it is relieved by the elastic force of the spring 15, and the wedge block 14 automatically pops outward to lock the inner ring 19. The steel strip 2 drives the temperature sensor 3 to be pushed to a position close to the outer ring 10, and the outer ring 10 and the outer ring 18 limit the two sides of the steel strip 2 to prevent the steel strip 2 from undergoing axial displacement relative to the plum blossom contact 1 during the operation of the equipment.

[0033] Example 3:

[0034] Please see Figures 5 to 6 The present invention provides a technical solution: an unlocking ring 20 is provided on the inner side of the guide rod 12, and a guide groove 21 is provided through the surface of the unlocking ring 20. The unlocking ring 20 is slidably connected to the sliding ring 23 through the guide groove 21.

[0035] An inclined rail 22 is fixedly connected to the inner surface of the unlocking ring 20. The number of inclined rails 22 is adapted to the connecting rod 17 and abuts against its surface. The inclined rail 22 is arc-shaped.

[0036] The outer ring 18 is rotatably connected to a slip ring 23, and the inner surface of the slip ring 23 is fixedly connected to several levers 24;

[0037] Several blocks 25 are fixedly connected to the front side of the unlocking ring 20, and the surface of the blocks 25 abuts against the surface of the lever 24.

[0038] An arc ring 26 is fixedly connected to the outer surface of the slip ring 23. A spring 3 27 is sleeved on the arc ring 26. One side of the spring 3 27 abuts against the outer ring 2 18.

[0039] In this embodiment, when it is necessary to remove the temperature sensor 3 from the plum blossom contact 1, the operator rotates the slip ring 23 clockwise on the outer ring 28. As the slip ring 23 slides on the outer ring 28, it drives the lever 24 to move the corresponding stop 25. The stop 25 is moved by the lever 24, causing the unlocking ring 20 to rotate and compressing the spring 3 27. When the unlocking ring 20 rotates, the inclined rail 22 fixedly installed on its inner side will lift the connecting rod 17 at the bottom of the insertion post 13 during continuous rotation. The connecting rod 17 triggers the insertion post 13 to retract inward. During this process, the locking rod 16 disconnects from the guide rod 12, and the wedge block 14 compresses the spring 15, causing the wedge block 14 to retract into the guide rod 12. At this time, the inner ring 19 disconnects from the wedge block 14. The operator slides the outer ring 18 backward, increasing the distance between the outer ring 18 and the outer ring 10, thus disconnecting the axial limit on the steel strip 2 and the temperature sensor 3. The temperature sensor 3 can then be removed by releasing the tension spring 7.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
