Description

Technical Field

[0001] This utility model relates to the field of intelligent measurement switch technology, and in particular to an HPLC communication-enhanced intelligent measurement switch. Background Technology

[0002] The HPLC communication-enhanced intelligent measurement switch is an IoT-sensing low-voltage switch adapted to the construction of ubiquitous power IoT. Essentially, it is an intelligent circuit breaker that integrates a high-speed power line carrier (HPLC) communication module. It not only has the power distribution protection capabilities of traditional switches, but also realizes intelligent functions such as electrical parameter monitoring and remote data transmission by relying on enhanced HPLC communication. It is widely used in metering boxes, branch boxes and other scenarios in low-voltage distribution substations.

[0003] When staff inspect the equipment in the metering box or branch box of the low-voltage distribution area, or the power distribution lines connected to the back end of the switch, they need to manually move the lever to the open position to ensure that the circuit is de-energized in order to carry out the maintenance. However, during the maintenance process, there is a risk of staff operation errors or non-maintenance personnel accidentally touching the switch, resulting in electrical continuity and leaving the staff in an electrically exposed environment, which poses a risk of electric shock. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] An HPLC communication-enhanced intelligent measurement switch includes:

[0006] The measurement switch body includes a measurement switch housing. A lever body is connected internally to the upper end of the measurement switch housing. The lever body includes a C-shaped plate. A connecting plate is provided on the inner side of the C-shaped plate. A hollow plate slides on the outer surface of one end of the connecting plate. An arc plate is connected to one end of the hollow plate. A lever is fixed to one inclined side of the arc plate. A T-shaped rod is connected to the inner side of the hollow plate. A cylinder is provided at the end of the T-shaped rod away from the hollow plate. A locking assembly is connected to the inner side of the middle portion of the C-shaped plate. An elastic assembly is also connected to the inner side of the middle portion of the C-shaped plate.

[0007] As an improvement to the above technical solution, a slot is provided on the upper part of the measuring switch housing, and a threaded groove is provided on the outer surface of one side of the measuring switch housing. The outer side of the C-shaped plate is connected to the inside of the measuring switch housing.

[0008] As an improvement to the above technical solution, an HPLC communication module is provided inside the bottom of the measuring switch housing. A rotating block is connected to the outer surface of the bottom of the measuring switch housing and below the HPLC communication module. A transparent cover is rotatably attached to one end of the rotating block, and a threaded groove is connected to one side of the transparent cover.

[0009] As an improvement to the above technical solution, a spring is provided inside the hollow plate. One end of the spring is connected to one end of the connecting plate, and the other end of the spring is connected to one side of the arc plate. A rotating rod is connected to one end of the connecting plate and the rotating rod rotates inside the C-shaped plate.

[0010] As an improvement to the above technical solution, one end of the T-shaped rod is connected to a trapezoidal block, the inclined surface of the trapezoidal block is provided with a slot, one end of the trapezoidal block is connected to a connecting rod, and one end of the connecting rod is connected to both ends of the cylinder.

[0011] As an improvement to the above technical solution, the locking assembly includes a second fixed block, a second rotating rod, a first arc-shaped locking plate, and a second arc-shaped locking plate. One end of the second fixed block is connected to the inner side of the C-shaped plate, one end of the second rotating rod rotates inside the second fixed block, and the other end of the second rotating rod passes through the intersection of the first arc-shaped locking plate and the second arc-shaped locking plate.

[0012] As an improvement to the above technical solution, the elastic component includes a second spring and a second connecting plate. One end of the second spring is connected to the inner side of the C-shaped plate, and the other end of the second spring is connected to one side of the second connecting plate.

[0013] As an improvement to the above technical solution, one end of the connecting plate two is connected to the outer arc surface of the arc plate one and the arc plate two, and a locking block is connected to one side of the connecting plate two.

[0014] The beneficial effects of this utility model are:

[0015] Pressing the lever causes the cylinder to press against the locking assembly. After the locking assembly opens, it pushes the cylinder to the inside of the first and second arc-shaped locking plates. The elastic force of the second spring causes the first and second arc-shaped locking plates to close again, locking the cylinder. The inclined surface of the trapezoidal block is attached to one side of the connecting plate, and the locking block is inserted into the slot, preventing the lever from rotating and preventing the lever from moving, thus preventing accidental activation.

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0024] In existing HPLC communication-enhanced intelligent measurement switches, there is a risk of electrical continuity during appliance maintenance due to operator error or accidental activation by unauthorized personnel. This could expose workers to electrical shock.

[0025] See appendix Figures 1-5 As shown, to solve the above-mentioned technical problems, an HPLC communication-enhanced intelligent measurement switch is provided, including: a measurement switch body 10, the measurement switch body 10 including a measurement switch housing 11, a lever body 20 connected to the upper end of the measurement switch housing 11, the lever body 20 including a C-shaped plate 21, a connecting plate 22 disposed on the inner side of the C-shaped plate 21, a hollow plate 23 sliding on the outer surface of one end of the connecting plate 22, an arc plate 24 connected to one end of the hollow plate 23, a lever 25 fixed on one side of the inclined surface of the arc plate 24, a T-shaped rod 26 connected to the inner side of the hollow plate 23, a cylinder 27 disposed at the end of the T-shaped rod 26 away from the hollow plate 23, a locking component 28 connected to the inner side of the middle part of the C-shaped plate 21, and an elastic component 29 connected to the inner side of the middle part of the C-shaped plate 21.

[0026] The toggle lever 25 rotates inside the C-shaped plate 21 via the connecting plate 22, achieving a switch effect. During maintenance, toggling the toggle lever 25 achieves a closed effect, ensuring a power-off environment when repairing electrical appliances or measuring the switch housing 11. Then, pressing the toggle lever 25 inward causes the hollow plate 23 to slide along one end of the connecting plate 22 via the arc plate 24, moving the T-shaped rod 26 closer to the C-shaped plate 21. This causes the cylinder 27 connected to the T-shaped rod 26 to press against the engaging assembly 28, while the elastic assembly 29 deforms under pressure. Position the cylinder 27 inside the engaging assembly 28, while the inclined surface of the trapezoidal block 261 is close to one side of the connecting plate 292, allowing the locking block 293 to be inserted into the locking slot 2611. When the elastic component 29 begins to rebound, it drives the engaging assembly 28 back to its original position, clamping the cylinder 27 inside the engaging assembly 28, ensuring that the T-shaped rod 26 is locked, thereby ensuring that the actuating rod 25 is locked, preventing it from rotating left or right, and preventing the actuating rod 25 from rotating back to its original position. To release the fixation, simply reverse the above steps and pull the actuating rod 25 upwards.

[0027] See Figure 1 , Figure 2 The upper part of the measuring switch housing 11 has a slot 111, and the outer surface of one side of the measuring switch housing 11 has a threaded groove 112. The outer side of the C-shaped plate 21 is connected to the inside of the measuring switch housing 11. The bottom of the measuring switch housing 11 is equipped with an HPLC communication module 12. The outer surface of the bottom of the measuring switch housing 11 and below the HPLC communication module 12 is connected to a rotating block 13. One end of the rotating block 13 is rotated with a transparent cover 14, and one side of the transparent cover 14 is connected to a threaded groove 141.

[0028] The housing 11 of the measurement switch is the main body of the HPLC communication-enhanced intelligent measurement switch. It contains different modules, such as input / output units, which are responsible for detecting the opening and closing status of the switch and outputting active and reactive power pulse signals. The HPLC communication module 12 is the "data transmission core" of the HPLC communication-enhanced intelligent measurement switch. Its core function is to realize stable data interaction between the switch and the power grid system and other equipment by relying on high-speed power line carrier technology, and to support the implementation of the intelligent functions of the switch. The transparent cover 14 is rotated by the rotating block 13, and the threaded groove 141 is the same size as the threaded groove 112. The transparent cover 14 is fixed by screwing on the bolts. When the transparent cover 14 is in the closed state, it is used to protect the HPLC communication module 12.

[0029] See Figure 2 , Figure 3A spring 231 is installed inside the hollow plate 23. One end of the spring 231 is connected to one end of the connecting plate 22, and the other end of the spring 231 is connected to one side of the arc plate 24. One end of the connecting plate 22 is connected to a rotating rod 221, and the rotating rod 221 rotates inside the C-shaped plate 21. One end of the T-shaped rod 26 is connected to a trapezoidal block 261. The inclined surface of the trapezoidal block 261 is provided with a slot 2611. One end of the trapezoidal block 261 is connected to a connecting rod 262, and one end of the connecting rod 262 is connected to both ends of the cylinder 27.

[0030] The spring 231 inside the hollow plate 23 ensures that after the hollow plate 23 is compressed, it provides elasticity to return the hollow plate 23 to its original position. The elasticity of the hollow plate 23 is less than that of the spring 291, ensuring that the arc-shaped clamping plates 283 and 284 can hold the cylinder 27. The hollow plate 23 can drive the T-shaped rod 26 to slide, allowing the cylinder 27 connected by the connecting rod 262 to be inserted into the inner side of the arc-shaped clamping plates 283 and 284, while simultaneously... When the lever 25 is in the closed state, the inclined surface of the trapezoidal block 261 is at the same horizontal line as the connecting plate 292. After the cylinder 27 is closed, the trapezoidal block 261 and the connecting plate 292 fit together, allowing the locking block 293 to be inserted into the locking slot 2611. When the lever 25 is in the closed state, when the lever 25 is pushed, the end of the arc-shaped locking plate 284 near the C-shaped plate 21 abuts against the inner side of the C-shaped plate 21, thereby ensuring that the lever 25 cannot be pushed.

[0031] See Figure 4 , Figure 5 The engaging assembly 28 includes a second fixing block 281, a second rotating rod 282, a first arc-shaped locking plate 283, and a second arc-shaped locking plate 284. One end of the second fixing block 281 is connected to the inner side of the C-shaped plate 21. One end of the second rotating rod 282 rotates inside the second fixing block 281. The other end of the second rotating rod 282 passes through the intersection of the first arc-shaped locking plate 283 and the second arc-shaped locking plate 284. The elastic assembly 29 includes a second spring 291 and a second connecting plate 292. One end of the second spring 291 is connected to the inner side of the C-shaped plate 21. The other end of the second spring 291 is connected to one side of the second connecting plate 292. One end of the second connecting plate 292 is connected to the outer arc surface of the first arc-shaped locking plate 283 and the second arc-shaped locking plate 284. A locking block 293 is connected to one side of the second connecting plate 292.

[0032] Fixed block 281 is used to restrict the position of arc-shaped clamping plate 283 and arc-shaped clamping plate 284. Rotating rod 282 ensures that arc-shaped clamping plate 283 and arc-shaped clamping plate 284 can rotate. When cylinder 27 is inserted into arc-shaped clamping plate 283 and arc-shaped clamping plate 284, it first squeezes arc-shaped clamping plate 283 and arc-shaped clamping plate 284, causing arc-shaped clamping plate 283 and arc-shaped clamping plate 284 to open and drive connecting plate 292 to move. At the same time, it squeezes spring 291 to deform it. When half of cylinder 27 enters arc-shaped clamping plate 283 and arc-shaped clamping plate 284, spring 291 opens back. The spring-loaded connecting plate 292 moves back to its original position, causing the arc-shaped clamping plates 283 and 284 to close, thus clamping the cylinder 27. At the same time, the inclined surface of the trapezoidal block 261 is attached to one side of the connecting plate 292, and the clamping block 293 is inserted into the slot 2611. When the actuating rod 25 is pushed, the slot 2611 will be moved. When the trapezoidal block 261 is clamped by the clamping block 293, the end of the arc-shaped clamping plate 284 connected to the clamping block 293 near the C-shaped plate 21 will abut against the inner side of the C-shaped plate 21, preventing the T-shaped rod 26 from rotating and ensuring that the actuating rod 25 cannot rotate.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
