Description

Technical Field

[0001] The utility model relates to the technical field of embedded waterproof electric energy metering boxes, and more specifically, it relates to an embedded waterproof electric energy metering box. Background Technique

[0002] In the existing technology, as an important electric energy metering device, the embedded waterproof electric energy metering box plays a key role in outdoor or humid environments. However, during the use of this metering box, it needs to be connected to external cables to achieve electric energy measurement and data transmission. Unfortunately, the existing connection methods have certain deficiencies in ensuring the waterproof effect, which may reduce the overall waterproof performance of the device, thereby affecting its stability and reliability in harsh environments.

[0003] First of all, when connecting to external cables, the existing embedded waterproof electric energy metering boxes usually adopt traditional terminal blocks or socket-type connection methods. These connection points are often the weak links in waterproof performance because the contact surfaces between the cables and the terminals or sockets may not be completely sealed, resulting in the possibility of moisture, humidity, or other external substances penetrating into the box body. In this case, even if the metering box itself has a high level of waterproof ability, the defects at the connection points will greatly reduce the overall waterproof effect and increase the risk of equipment failure.

[0004] Secondly, due to the connection method, the embedded waterproof electric energy metering box may cause damage to the internal circuit due to water seepage at the cable connection during long-term use, affecting the accuracy of electric energy metering, and even may cause the equipment to fail. In addition, the decline in the waterproof performance of the connection may also increase the maintenance cost because it is necessary to regularly check and replace damaged connection components. This not only affects the normal operation of the equipment but also increases the difficulty and cost of operation and maintenance work. Content of the Utility Model

[0030] Please refer to Figures 1-5, An embedded waterproof electric energy metering box, including a high-voltage box body 1, the high-voltage box body 1 is embedded and installed on an external device, a sealing mechanism is provided on the high-voltage box body 1, the sealing mechanism includes a protective cover 2, a fixed sleeve 3, a positioning disc 4, a rotating sleeve 5, a limiting sleeve 6, a rubber ring 7, a fixing ring 8, an insertion rod 9, a clamping mechanism and a rotating mechanism. The protective cover 2 is installed on the high-voltage box body 1, the fixed sleeve 3 is installed on the protective cover 2, the positioning disc 4 is installed on the fixed sleeve 3, the positioning disc 4 fits on the protective cover 2, the rotating sleeve 5 is threadedly connected to the fixed sleeve 3, the limiting sleeve 6 is installed on the rotating sleeve 5, the rubber ring 7 is installed on the rotating sleeve 5, the fixing ring 8 is slidably connected to the rubber ring 7, there are multiple insertion rods 9, and one ends of the multiple insertion rods 9 are connected to the fixing ring 8, and the other ends of the multiple insertion rods 9 are slidably connected to the limiting sleeve 6. The clamping mechanism and the rotating mechanism are inside the fixed sleeve 3. There are follower sleeves 10 provided on the multiple insertion rods 9 respectively, and push springs 11 are provided on the follower sleeves 10, and the push springs 11 abut against the limiting sleeve 6. There are multiple insertion rods 9, and the multiple insertion rods 9 are inserted into the positioning disc 4. The rotating mechanism includes a hexagonal sleeve 12 and overload springs 13. The hexagonal sleeve 12 is installed on the rotating sleeve 5, there are multiple overload springs 13, and the multiple overload springs 13 are respectively installed on the inner wall of the hexagonal sleeve 12. A follower ring 14 is rotatably provided inside the fixed sleeve 3, there are multiple push bars 15 provided on the side wall of the follower ring 14, and the overload springs 13 abut against the push bars 15. There are multiple follower grooves 16 provided on the side wall of the follower ring 14. The clamping mechanism includes rubber strips 17 and an inner sleeve 18. There are multiple rubber strips 17, and the multiple rubber strips 17 are respectively connected to the follower ring 14 and the inner sleeve 18. There are multiple clamping strips 19 provided on the inner sleeve 18, and the clamping strips 19 are stuck on the fixed sleeve 3. A bottom ring 20 is threadedly provided on the inner sleeve 18, and the bottom ring 20 is stuck on the fixed sleeve 3. The multiple rubber strips 17 respectively abut against the side wall of the cable.

[0031] In this embodiment, when it is necessary to seal the cable, first, the hexagonal sleeve 12 is used to drive the overload spring 13 to abut against the push bar 15. Since the rotating sleeve 5 is threadedly connected to the fixed sleeve 3, it will drive the follower ring 14 to drive the rubber strip 17 to rotate and clamp on the cable. Then it will drive the follower ring 14 to slide downward, and then the multiple rubber strips 17 will approach each other, applying corresponding clamping force and sealing between the multiple rubber strips 17 at the same time, so as to achieve the sealing effect. When the clamping force exceeds the elastic force of the overload spring 13, the clamping between the overload spring 13 and the push bar 15 will be released, thus completing the process of fixed sealing.

[0032] More specifically, when it is necessary to fix after completing the sealing and clamping, since the fixing ring 8 is stuck on the rubber ring 7 at this time, the thrust of the push spring 11 is less than the frictional force at this time. Then when completing the clamping, the fixing ring 8 is pushed to release the clamping with the rubber ring 7, and then under the action of the push spring 11, the insertion rod 9 is inserted into the positioning disc 4, thus completing the fixation of the limiting disc and the positioning disc 4.

[0033] In summary, when the overall device is in use or operation: when the cable needs to be sealed, first, the hexagonal sleeve 12 drives the overload spring 13 to press against the push bar 15. Since the rotating sleeve 5 is threadedly connected to the fixed sleeve 3, it will drive the follower ring 14 to drive the rubber strip 17 to rotate and clamp on the cable. Then, it will drive the follower ring 14 to slide downward, and then the obtained multiple rubber strips 17 will approach each other, sealing between the multiple rubber strips 17 while applying the corresponding clamping force, thus achieving the sealing effect. When the clamping force exceeds the elastic force of the overload spring 13, the clamping between the overload spring 13 and the push bar 15 will be released, thus completing the process of fixed sealing.

[0034] When it is necessary to fix after completing the sealing and clamping, since the fixing ring 8 is clamped on the rubber ring 7 at this time, the thrust of the push spring 11 is less than the frictional force at this time. Then, when the clamping is completed, the fixing ring 8 is pushed to release the clamping with the rubber ring 7, and then under the action of the push spring 11, the insertion rod 9 is inserted into the positioning disk 4, thus completing the fixation of the limiting disk and the positioning disk 4.
