Description

Technical Field

[0001] This invention relates to the field of lightning protection device technology, and more particularly to a lightning arrester device. Background Technology

[0002] In the field of power distribution networks, controlled discharge lightning rods have a considerably large protection zone that is almost entirely free from backflashover. The discharge time of a controlled discharge lightning rod is on average 13.3 µs earlier than that of a Franklin lightning rod. When the simulated electric field is relatively low, the corona current of a controlled discharge lightning rod is much lower than that of a Franklin lightning rod, almost completely suppressed. Furthermore, when the simulated electric field increases to a level sufficient to activate the controlled discharge lightning rod, it generates a pulsed corona discharge current. The amplitude of this corona current is tens of times larger than that of a Franklin lightning rod, but the average value of the corona current is smaller. This facilitates the transition from corona discharge to pre-conduction arcing.

[0003] However, existing controllable discharge lightning rods have the following drawbacks:

[0004] 1. The top of the lightning rod is designed with a sharp point and has no protective measures. The controlled discharge lightning rod is easy to injure people during installation, transportation and handling. At the same time, the top of the lightning rod may be damaged by bumps during installation, transportation and handling, which will affect its subsequent use and has poor stability.

[0005] 2. The electrically controlled discharge lightning rod is a one-piece fixed structure that cannot be folded or extended. This results in the lightning rod occupying a large space during transportation and installation, making it inconvenient to transport. During installation, it reduces the operating space for workers, resulting in low work efficiency, poor flexibility and adaptability, and low practicality.

[0006] Therefore, a surge protector is needed to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a lightning protection device that can prevent damage to the lightning rod and injury to personnel, and is easy to transport and install.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] Lightning protection devices, including:

[0010] Mounting base, wherein a positioning groove is provided on the mounting base;

[0011] The installation control component is disposed in the mounting base and extends relative to the positioning groove. The installation control component has a first control position and a second control position relative to the mounting base, with the first control position located above the second control position.

[0012] The lightning rod body is inserted into the installation control assembly and connected to the grounding device;

[0013] Multiple linkage assemblies are arranged at circumferential intervals along the mounting base. The linkage assemblies are hinged to the mounting base and the mounting control assembly. When the mounting control assembly is in the first control position, the lightning rod body is located in the mounting control assembly, and the linkage assembly is folded up. When the mounting control assembly is in the second control position, the lightning rod body extends out relative to the mounting control assembly, and the linkage assembly is unfolded.

[0014] A dynamic ring is disposed on the extended link assembly.

[0015] Furthermore, the installation control assembly includes a control rod and a guide locking assembly. A through hole is formed on the control rod along its axial direction, and the lightning rod body is inserted into the through hole. The control rod is disposed in the positioning groove and is hinged to the connecting rod assembly. The guide locking assembly is disposed in the mounting base and can lock the control rod so that the control rod is in the first control position or the second control position.

[0016] Furthermore, the guide locking assembly includes a guide member and an elastic member. The guide member is disposed in the mounting base. One end of the elastic member abuts against the guide member, and the other end of the elastic member abuts against the mounting base. A locking structure is provided between the guide member and the control rod. The locking structure can lock the control rod so that the control rod is in the first control position or the second control position.

[0017] Furthermore, the locking structure includes a drive rod, which is disposed on the control rod. The guide member has a V-shaped groove, which includes an upward groove and a downward groove that are interconnected. The drive rod is slidably disposed in the V-shaped groove. When the drive rod is located at the upper end of the upward groove, the control rod is in the first control position. When the drive rod is located at the lower end of the downward groove, the control rod is in the second control position.

[0018] Furthermore, the linkage assembly includes a diagonal tie rod and a transverse tie rod. One end of the diagonal tie rod is hinged to the mounting base, one end of the transverse tie rod is hinged to the control rod, and the other end of the transverse tie rod is hinged to the diagonal tie rod. The upper end of the diagonal tie rod is used to fix the dynamic ring.

[0019] Furthermore, the upper end of the tie rod is provided with a snap-fit ​​groove, and the dynamic ring is snapped into the snap-fit ​​groove.

[0020] Furthermore, a locking structure is provided between the dynamic ring and the tie rod, the locking structure being used to lock the relative position between the tie rod and the dynamic ring.

[0021] Furthermore, the locking structure includes a locking rod that slides through the upper end of the tie rod, and a locking groove is provided on the dynamic ring, allowing the locking rod to be inserted into the locking groove to lock the dynamic ring.

[0022] Furthermore, a compression spring is fitted onto the locking rod, with one end of the compression spring abutting against the locking rod and the other end abutting against the inclined pull rod. The compression spring always tends to keep the locking rod in the locking groove.

[0023] Furthermore, the locking rod has an L-shaped functional groove, including a horizontal groove and a vertical groove that are interconnected. The tie rod has a positioning protrusion located in the functional groove. When the positioning protrusion is located in the horizontal groove, the locking rod can be inserted into the locking groove. When the positioning protrusion is located in the vertical groove, the locking rod disengages from the locking groove.

[0024] The beneficial effects of this invention are:

[0025] This invention provides a lightning arrester device with an installation control component housed in a mounting base. The installation control component extends from the positioning slot of the mounting base, and a lightning rod is inserted into the installation control component. Multiple connecting rod assemblies are arranged between the mounting base and the installation control component. When the installation control component is in the first control position, the lightning rod is located within the installation control component, and the connecting rod assemblies are folded up. The installation control component protects the lightning rod, preventing injury or damage from its tip. Furthermore, the folded connecting rod assemblies facilitate transportation. During installation, the installation control component is moved to the second control position, the lightning rod extends from the installation control component, and the connecting rod assemblies unfold. A dynamic ring is then installed on the unfolded connecting rod assemblies. This method facilitates transportation and installation. Moreover, the ability to fold and unfold the connecting rod assemblies ensures sufficient operating space and installation flexibility. Attached Figure Description

[0042] Example 1

[0043] In the field of power distribution networks, when using controlled discharge lightning rods for anti-slip purposes, in order to prevent damage to the lightning rod body and injury to personnel, and to facilitate transportation and installation, such as... Figures 1-11 As shown, the present invention provides a surge protector device. The surge protector device includes a mounting base 101, a mounting control assembly 1, a lightning rod body 103, multiple linkage assemblies 2, and a dynamic ring 3.

[0044] The mounting base 101 has a positioning groove 1011. A mounting control component 1 is disposed within the mounting base 101, extending out of the positioning groove 1011. The mounting control component 1 has a first control position and a second control position relative to the mounting base 101, with the first control position located above the second control position. A lightning rod body 103 is inserted into the mounting control component 1 and connected to a grounding device. Multiple connecting rod assemblies 2 are spaced circumferentially along the mounting base 101. The connecting rod assemblies 2 are hinged to the mounting base 101 and the mounting control component 1. When the mounting control component 1 is in the first control position, the lightning rod body 103 is located within the mounting control component 1, and the connecting rod assemblies 2 are folded up. When the mounting control component 1 is in the second control position, the lightning rod body 103 extends out of the mounting control component 1, and the connecting rod assemblies 2 are unfolded. A dynamic ring 3 is disposed on the unfolded connecting rod assembly 2.

[0045] When the installation control component 1 is in the first control position, the lightning rod body 103 is located within the installation control component 1, and the connecting rod assembly 2 is folded up. The installation control component 1 protects the lightning rod body 103, preventing injury or damage from its tip. Furthermore, the folded-up state of the connecting rod assembly 2 facilitates transportation. During installation, the installation control component 1 is moved to the second control position, the lightning rod body 103 extends relative to the installation control component 1, and the connecting rod assembly 2 unfolds. A dynamic ring 3 is then installed on the unfolded connecting rod assembly 2. This method facilitates transportation and installation. Moreover, the ability to fold and unfold the connecting rod assembly 2 ensures sufficient operating space and installation flexibility.

[0046] Further, the installation control assembly 1 includes a control rod 102 and a guide locking assembly. A through hole is formed on the control rod 102 along its axial direction, and the lightning rod body 103 is inserted into the through hole. The control rod 102 is slidably disposed in the positioning groove 1011 and is hinged to the connecting rod assembly 2. The guide locking assembly is disposed in the mounting base 101 and can lock the control rod 102, so that the control rod 102 is in a first control position or a second control position. Specifically, in order to prevent the control rod 102 from rotating relative to the mounting base 101 when it moves in the first control position and the second control position, in this embodiment, the positioning groove 1011 on the mounting base 101 is a quadrilateral groove, and the cross-section of the control rod 102 is a quadrilateral that matches the positioning groove 1011. Using the above method, the rotation of the control rod 102 relative to the positioning groove 1011 can be prevented. During transportation, the control lever 102 is in the first control position for easy transport; when installation is required, the control lever 102 is moved to the second control position. In other embodiments, the shape of the mounting groove and the control lever 102 can be designed according to actual needs, and no further restrictions are imposed here.

[0047] Furthermore, the guide locking assembly includes a guide member 104 and an elastic member 1042. The guide member 104 is slidably disposed in the mounting base 101. One end of the elastic member 1042 abuts against the guide member 104, and the other end of the elastic member 1042 abuts against the mounting base 101. A locking structure is provided between the guide member 104 and the control lever 102. The locking structure can lock the control lever 102, so that the control lever 102 is in a first control position or a second control position. Specifically, the elastic member 1042 is a compression elastic member. With the locking structure provided between the guide member 104 and the control lever 102, during the movement of the control lever 102, the guide member 104 moves relative to the mounting base 101, thereby compressing the elastic member 1042. The elastic force of the elastic member 1042 acts on the locking structure to lock the control lever 102.

[0048] Furthermore, such as Figure 3As shown, the locking structure includes a drive rod 1021, which is fixedly mounted on the control rod 102. A V-shaped groove 141 is provided on the guide member 104. The V-shaped groove 141 includes an upward groove 1411 and a downward groove 1412 that are interconnected. The drive rod 1021 is slidably mounted in the V-shaped groove 141. When the drive rod 1021 is located at the upper end of the upward groove 1411, the control rod 102 is in the first control position. When the drive rod 1021 is located at the lower end of the downward groove 1412, the control rod 102 is in the second control position. Specifically, when the control lever 102 moves from the first control position to the second control position, the drive lever 1021 moves in the upward groove 1411, thereby pushing the guide member 104 to compress the elastic member 1042. At this time, during the compression process, the elastic member 1042 applies a resistance torque to the control lever 102 through the guide member 104. During the continued movement, the drive lever 1021 slides into the downward groove 1412. At this time, under the action of its own elastic restoring force, the elastic member 1042 pushes the control lever 102 to move quickly down to the bottom of the downward groove 1412. In this process, the linkage assembly 2 is deployed. Moreover, the force of the elastic member 1042 can lock the relative position between the control lever 102 and the mounting base 101.

[0049] Furthermore, the linkage assembly 2 includes a diagonal tie rod 202 and a horizontal tie rod 201. One end of the diagonal tie rod 202 is hinged to the mounting base 101, and one end of the horizontal tie rod 201 is hinged to the control rod 102. The other end of the horizontal tie rod 201 is hinged to the diagonal tie rod 202. The upper end of the diagonal tie rod 202 is used to fix the dynamic ring 3. During the movement of the control rod 102 from the first control position to the second control position, the diagonal tie rod 202 and the horizontal tie rod 201 unfold. After the control rod 102 moves to the second control position, the horizontal tie rod 201 and the diagonal tie rod 202 are fully unfolded. Then, the dynamic ring 3 is installed on the diagonal tie rod 202 to limit the linkage assembly 2 and ensure the stability of the surge protector after installation.

[0050] Furthermore, the upper end of the tie rod 202 is provided with a snap-fit ​​groove, in which the dynamic ring 3 is snapped. The snap-fit ​​groove facilitates the positioning and installation of the dynamic ring 3.

[0051] Furthermore, a locking structure is provided between the dynamic ring 3 and the tie rod 202. The locking structure is used to lock the relative position between the tie rod 202 and the dynamic ring 3. By providing the locking structure, the relative position between the dynamic ring 3 and the tie rod 202 can be locked, ensuring the stability of the dynamic ring 3 installation.

[0052] Furthermore, the locking structure includes a locking rod 203, which slides through the upper end of the tie rod 202. A locking groove 301 is provided on the dynamic ring 3, and the locking rod 203 can be inserted into the locking groove 301 to lock the dynamic ring 3. Specifically, an installation hole communicating with a snap-fit ​​groove is provided at the upper end of the tie rod 202. The locking rod 203 passes through the installation hole. After the dynamic ring 3 is installed, the locking rod 203 is inserted into the locking groove 301, thus achieving the installation and fixation of the dynamic ring 3 on the tie rod 202.

[0053] Furthermore, a compression spring 2032 is fitted onto the locking rod 203. One end of the compression spring 2032 abuts against the locking rod 203, and the other end abuts against the tie rod 202. The compression spring 2032 always tends to keep the locking rod 203 in the locking groove 301. By setting the compression spring 2032, it is possible to ensure that the head of the locking rod 203 is stably inserted into the locking groove 301.

[0054] Furthermore, in order to quickly position the dynamic ring 3, limiting protrusions are provided on both sides of the locking groove 301. The limiting protrusions cooperate with the diagonal tie rod 202 for positioning, so as to realize the rapid installation of the dynamic ring 3.

[0055] Example 2

[0056] The biggest difference between this embodiment and Embodiment 1 is that a positioning structure is provided between the locking rod 203 and the tie rod 202. All other structures are the same, and only the positioning structure will be discussed here.

[0057] Furthermore, the positioning structure includes a positioning protrusion 2021, and an L-shaped functional groove 2031 on the locking rod 203, including a transverse groove and a vertical groove that are interconnected. The positioning protrusion 2021 is fixedly installed in the mounting hole of the tie rod 202. The positioning protrusion 2021 is located in the functional groove 2031. When the positioning protrusion 2021 is located in the transverse groove, the locking rod 203 can be inserted into the locking groove 301. When the positioning protrusion 2021 is located in the vertical groove, the locking rod 203 disengages from the locking groove 301. After the dynamic ring 3 is installed in place, the positioning protrusion 2021 on the tie rod 202 is located in the vertical groove. Under the push of the compression spring 2032, the locking rod 203 is inserted into the locking hole. At this time, the transverse groove plays a guiding role. When it is necessary to remove the dynamic ring 3, pull the locking rod 203 outward, and then rotate the locking rod 203 so that the positioning protrusion 2021 is located in the vertical groove, thereby positioning the locking rod 203. At this time, the locking rod 203 disengages from the locking groove 301, and the dynamic ring 3 can be removed.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
