Description

Technical Field

[0001] This utility model relates to the field of contact protection technology, and in particular to a high-current contact protection device. Background Technology

[0002] In fields such as power transmission, industrial equipment, and high-current switching devices, reliable protection of high-current contacts is crucial for ensuring the safe and stable operation of electrical systems. These contacts withstand high current loads for extended periods during operation and are susceptible to impact damage from external environmental factors; therefore, physical isolation and protection through protective devices are necessary.

[0003] Currently, to provide comprehensive protection for high-current contacts, a two-part protective structure is typically used. This two-part structure is designed to completely enclose the contacts to isolate them from adverse effects of the external environment. However, since the contacts need to be periodically inspected, cleaned, or replaced, maintenance requires repeated disassembly and reassembly of bolts. The large number of bolts makes the process cumbersome, consuming a lot of time and effort, and greatly reducing maintenance efficiency. Furthermore, frequent tightening and loosening of bolts can easily cause thread wear, stripping, or even breakage, affecting the sealing and mechanical strength of the protective structure. Long-term use may lead to the risk of protective failure. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a high-current contact protection device to solve the technical problem that the current maintenance process requires repeated disassembly and installation of bolts, which is cumbersome due to the large number of bolts, consumes a lot of time and energy, and greatly reduces maintenance efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A high-current contact protection device includes a fixed base with fixing holes. A bidirectional drive assembly is installed on the top of the fixed base. A semi-circular plate one and a semi-circular plate two are respectively installed on the two rotating ends of the bidirectional drive assembly. A connecting groove one and a connecting groove two are respectively opened on the opposite ends of the semi-circular plate one and the semi-circular plate two.

[0008] The bidirectional drive assembly includes a first rotating column and a second rotating column, with a transmission assembly installed at the opposite ends of the first rotating column and the second rotating column. The bottom end of the first rotating column is rotatably mounted on the top of the fixed chassis via a bearing, and the bottom end of the second semi-circular plate is fixed on the first rotating column. At the same time, the bottom end of the second semi-circular plate is rotatably connected to the first rotating column via a bearing. A knob is installed on the top end of the second rotating column, and the top end of the second semi-circular plate is fixed on the second rotating column. At the same time, the top end of the second semi-circular plate is rotatably connected to the second rotating column via a bearing.

[0009] As an improved technical solution, a U-shaped connecting frame is rotatably connected between the opposite ends of the rotating column two and the rotating column one. An installation shaft is rotatably installed in the middle of the inner cavity of the U-shaped connecting frame. A bevel gear three is installed at the end of the rotating column two near the rotating column one. A bevel gear one is installed at the end of the rotating column one near the rotating column two. A bevel gear two that meshes with bevel gear one and bevel gear three is installed at the end of the installation shaft near bevel gear one.

[0010] As an improved technical solution, the peripheral surfaces of the first semicircular plate and the second semicircular plate are provided with multiple heat dissipation grooves at equal intervals.

[0011] As an improved technical solution, a locking strip is fixed to the outer side of the semicircular plate one away from the bidirectional drive component, and a locking strip is fixed to the outer side of the semicircular plate two away from the bidirectional drive component. Magnetic strips are embedded in the opposite surfaces of the locking strip one and the locking strip two, and the opposite surfaces of the magnetic strips one on both sides are magnetically attracted to each other.

[0012] As an improved technical solution, a limiting component is installed between the two semicircular plates near the bidirectional drive assembly. The limiting component includes a limiting strip 1 and a limiting strip 2 respectively installed on the semicircular plates 1 and 2. A magnetic strip 3 is embedded in the opposite surfaces of the limiting strip 1 and the limiting strip 2, and the opposite surfaces of the magnetic strips 3 on both sides are magnetically attracted to each other.

[0013] As an improved technical solution, the first semicircular plate and the second semicircular plate are controlled by a bidirectional drive assembly to rotate simultaneously toward the center or both sides, and the bidirectional drive assembly and the second semicircular plate are brought together to form a protective cavity.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model can simultaneously drive the first semicircular plate and the second semicircular plate to rotate synchronously through a bidirectional drive component, eliminating the need to rotate the first and second semicircular plates separately, simplifying the assembly and disassembly process, and improving the efficiency of subsequent maintenance. Furthermore, when the first and second semicircular plates are brought together, the magnetic strips on both sides are in a combined contact state, and the two magnetic strips magnetically attract and reinforce the bringing together of the first and second semicircular plates, which helps to prevent the first and second semicircular plates from separating due to accidents and improves the stability of the protection.

[0016] 2. In this utility model, after the semi-circular plate one and the semi-circular plate two are separated, the magnetic strips three on both sides will be in a state of merging and contact. The two magnetic strips three enter and exit magnetically attract each other, fixing the separated semi-circular plate one and the semi-circular plate two, preventing them from being in a swinging state and affecting the maintenance work of the staff on the contact.

[0028] like Figures 1 to 4 As shown in the figure, this embodiment provides a high current contact protection device. This high current contact protection device includes a fixed base 1 with a fixing hole. A bidirectional drive assembly 2 is installed on the top of the fixed base 1. A semi-circular plate 3 and a semi-circular plate 4 are respectively installed on the two rotating ends of the bidirectional drive assembly 2. A connecting groove 31 and a connecting groove 41 are respectively opened on the opposite ends of the semi-circular plate 3 and the semi-circular plate 4.

[0029] The bidirectional drive assembly 2 includes a rotating column 1 21 and a rotating column 22, and a transmission assembly is installed at the opposite ends of the rotating column 1 21 and the rotating column 22. The bottom end of the rotating column 1 21 is rotatably mounted on the top of the fixed chassis 1 through a bearing, and the bottom end of the semi-circular plate 2 4 is fixed on the rotating column 1 21. At the same time, the bottom end of the semi-circular plate 3 is rotatably connected to the rotating column 1 21 through a bearing. A knob is installed at the top end of the rotating column 22, and the top end of the semi-circular plate 3 is fixed on the rotating column 22. At the same time, the top end of the semi-circular plate 4 is rotatably connected to the rotating column 22 through a bearing.

[0030] The bidirectional drive assembly 2 can simultaneously drive the semicircular plate 3 and the semicircular plate 4 to rotate synchronously, eliminating the need to rotate the semicircular plate 3 and the semicircular plate 4 separately, simplifying the assembly and disassembly process and improving the efficiency of subsequent maintenance.

[0031] like Figures 1 to 3 As shown in the figure, in this embodiment, a U-shaped connecting frame 23 is rotatably connected between the opposite ends of the rotating column 22 and the rotating column 21. An mounting shaft 24 is rotatably installed in the middle of the inner cavity of the U-shaped connecting frame 23. A bevel gear 27 is installed at the end of the rotating column 22 near the rotating column 21, and a bevel gear 25 is installed at the end of the rotating column 21 near the rotating column 22. A bevel gear 26 that meshes with the bevel gear 25 and the bevel gear 27 is installed at the end of the mounting shaft 24 near the bevel gear 25.

[0032] like Figures 1 to 2 As shown in the figure, in this embodiment, the peripheral surfaces of the first semicircular plate 3 and the second semicircular plate 4 are provided with multiple heat dissipation grooves 5 at equal intervals. The arrangement of heat dissipation grooves 5 on the first semicircular plate 3 and the second semicircular plate 4 is conducive to the heat of the contacts being dissipated to the outside.

[0033] like Figures 1 to 2 As shown in the figure, in this embodiment, a locking strip 6 is fixed to the outer side of the semicircular plate 3 away from the bidirectional drive assembly 2, and a locking strip 7 is fixed to the outer side of the semicircular plate 4 away from the bidirectional drive assembly 2. Magnetic strips 8 are embedded in the opposite surfaces of the locking strips 6 and 7, and the opposite surfaces of the two magnetic strips 8 are magnetically attracted to each other. When the semicircular plate 3 and the semicircular plate 4 are closed together, the two magnetic strips 8 are in a state of contact. The two magnetic strips 8 magnetically attract each other to reinforce the closure of the semicircular plate 3 and the semicircular plate 4, which helps to prevent the semicircular plate 3 and the semicircular plate 4 from separating due to accidents, thus improving the stability of the protection.

[0034] like Figure 1 and Figure 4 As shown in the figure, in this embodiment, a limiting component 9 is installed between the ends of the semicircular plate 3 and the semicircular plate 4 near the bidirectional drive assembly 2. The limiting component 9 includes a limiting strip 91 and a limiting strip 92 respectively installed on the semicircular plate 3 and the semicircular plate 4. A magnetic strip 93 is embedded in the opposite surface of the limiting strip 91 and the limiting strip 92, and the opposite surfaces of the magnetic strips 93 on both sides are magnetically attracted to each other. After the semicircular plate 3 and the semicircular plate 4 are separated, the magnetic strips 93 on both sides will be in a state of merging and contact. The two magnetic strips 93 magnetically attract each other, fixing the separated semicircular plate 3 and the semicircular plate 4, and preventing them from swinging and affecting the maintenance work of the contact.

[0035] like Figures 1 to 3 As shown in the figure, in this embodiment, the semi-circular plate 3 and the semi-circular plate 4 are controlled by the bidirectional drive assembly 2 to rotate simultaneously toward the center or both sides, and the bidirectional drive assembly 2 and the semi-circular plate 4 are brought together to form a protective cavity.

[0036] In use, the fixed base 1 is fixed to the side of the contact. After the semi-circular plate 3 and the semi-circular plate 4 are combined, they completely wrap around the contact, achieving physical isolation of the contact. The process of driving the bidirectional drive assembly 2 to bring the semi-circular plate 3 and the semi-circular plate 4 together is as follows:

[0037] When the knob drives the rotating column 22 to rotate counterclockwise, it will drive the semi-circular plate 3 to rotate counterclockwise. Under the transmission action of bevel gear 25, bevel gear 26 and bevel gear 3 27, the rotating column 22 drives the rotating column 21 to rotate clockwise, which will drive the semi-circular plate 4 to rotate clockwise. At this time, the semi-circular plate 3 and the semi-circular plate 4 rotate and close together in the direction of the semi-circular plate 4, and the contact is wrapped between the semi-circular plate 3 and the semi-circular plate 4 to achieve physical isolation.

[0038] Conversely, if the rotating column 22 is driven to rotate clockwise, the closed semicircular plate 3 and semicircular plate 4 will be separated, thus releasing the contact from its enclosure.

[0039] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
