Description

Technical Field

[0001] The invention belongs to the technical field of lightning protection safety detection, and more specifically, particularly relates to a telescopic and lengthened lightning protection safety detection device. Background Art

[0002] Lightning protection refers to avoiding the harm to human body, buildings, etc. caused by lightning through certain methods and measures. At present, lightning protection devices are installed on various building facilities, power lines and their ancillary equipment. It is necessary to regularly test the lightning protection performance of these lightning protection devices through special detection devices to ensure that the lightning protection devices can be used stably and play a lightning protection role.

[0003] For example, in the patent with application number: CN201610810597.5, a lightning protection type residual current operated circuit breaker is disclosed, including a leakage circuit breaker module and a lightning protection module S connected to the leakage circuit breaker module, the leakage circuit breaker module includes a zero-sequence mutual inductor L1 for detecting the residual current in the main circuit, and the power supply L phase and the power supply N phase pass through the zero-sequence mutual inductor L1; it also includes a backup protection circuit linked with the lightning protection module, the lightning protection module S is connected to the backup protection circuit, and the backup protection circuit is connected in parallel between the power supply L phase and the power supply N phase; when the lightning protection module S fails, the lightning protection module S triggers the backup protection circuit to connect, at this time, the zero-sequence mutual inductor L1 of the leakage circuit breaker module detects the residual current, and sends a control signal to the tripping mechanism of the circuit breaker to cut off the main circuit. The lightning protection type residual current operated circuit breaker of the present invention, after the lightning protection module fails, by connecting the backup protection circuit, the main circuit is cut off in time, and the lightning protection module and the leakage circuit breaker module cooperate with each other to protect the safety of electricity use.

[0004] Existing lightning protection detection devices are mostly clamped on the lightning protection device line or conductor rod for detection. If the lightning protection line or conductor rod is too high, it is necessary to use an extension rod to drive the clamp to clamp on the line or conductor rod. After extension, the opening and closing of the clamp cannot be controlled manually. The clamp is easy to fall off during detection, affecting the accuracy and efficiency of the lightning protection device performance detection, and is not very practical.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a telescopic extended lightning protection safety detection device is provided, in order to achieve a more practical purpose. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a telescopic extended lightning protection safety detection device to solve the problem that most existing lightning protection detection devices are clamped on the lightning protection device line or conductor rod for detection. If the lightning protection line or conductor rod is too high, it is necessary to drive the clamp to clamp on the line or conductor rod through an extension rod. After extension, the opening and closing of the clamp cannot be controlled manually, and the clamp is easy to fall off during detection, affecting the accuracy and detection efficiency of the lightning protection device performance detection, and the practicality is not high.

[0007] The purpose and effect of the telescopic extended lightning protection safety detection device of the present invention are achieved by the following specific technical means:

[0008] A telescopic extended lightning protection safety detection device comprises a telescopic extension rod, a detection clamp mechanism, an adjustment rod and a drive motor; the telescopic extension rod is fixedly connected to the bottom of a protective shell; the detection clamp mechanism consists of a left clamp and a right clamp; the left clamp and the right clamp are plugged into the interior of the protective shell; the adjustment rod is rotatably connected to the interior of the protective shell; the drive motor is fixed to the interior of the protective shell by screwing, and the drive motor is electrically connected to an external power supply and a control device.

[0009] Furthermore, a positioning hole is provided in the middle of the clamp body of the left clamp and the right clamp, and a positioning rod is rotatably connected inside the positioning hole, and the left clamp is located at the top of the clamp body of the right clamp.

[0010] Furthermore, the clamp bodies of the left clamp and the right clamp are in an "L" shape, and the left clamp and the right clamp are in a symmetrical design.

[0011] Furthermore, a control slide bar is provided at one end of the clamp body of the left clamp and the right clamp, and the control slide bar is symmetrical with the vertical bar of the corresponding clamp body of the detection clamp mechanism, and the control slide bar and the clamp body of the detection clamp mechanism are respectively located on both sides of the positioning hole.

[0012] Furthermore, the top and bottom of the positioning rod body are provided with track blocks, and the block shape of the track block is a "T"-shaped design. The shells at the top and bottom of the protective shell are provided with track grooves, and the track blocks are inserted into the inside of the track grooves.

[0013] Furthermore, a threaded hole is provided inside the block body of the track block, and a thread is provided outside the middle rod body of the adjusting rod, and the adjusting rod is screwed into the threaded hole of the track block through the rod body thread.

[0014] Furthermore, a synchronous gear is provided at the outer end of the adjusting rod, and two adjusting rods are provided inside the protective shell, a driving gear is provided at one end of the rotating rod of the driving motor, and the two adjusting rods are symmetrically distributed on both sides of the driving gear, and the gear teeth at the top and bottom of the driving gear are respectively connected to the synchronous gears at one end of the two adjusting rods.

[0015] Furthermore, two groups of control grooves are provided inside the protective shell, and the two groups of control grooves are respectively arranged at the top and bottom of the protective shell, each group of control grooves is provided with two symmetrical groove bodies, and the direction of the two groove bodies of each group of control grooves is an "eight" shape, and the top and bottom rod bodies of the control slide rod are respectively inserted into the control grooves at the top and bottom of the protective shell.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the device is testing a higher line or conductor rod, the protective shell can be controlled to move to the line or conductor rod position by the telescopic extension rod, and then the detection clamp mechanism can be automatically extended from the inside of the protective shell and clamped on the line or conductor rod under the drive of the driving motor. The clamping is stable and will not fall off. The performance of the lightning protection device can be stably tested through the line or conductor rod of the lightning protection device, and the data is accurate. The reversal of the driving motor can make the detection clamp mechanism automatically reset and shrink to be hidden in the protective shell, so as to avoid damage to the detection clamp mechanism. The working efficiency is high, the use is convenient and quick, and the practicality of the device is improved.

[0018] Firstly, the detection clamp mechanism has two clamps, one upper and one lower. The left clamp and the right clamp can stably clamp in an offset manner, and can adapt to the clamping contact detection of lines and conductor rods of different thicknesses. The "L"-shaped design of the left clamp and the right clamp enables the left clamp and the right clamp to be hung on the line or the conductor rod after clamping, thereby increasing the contact area between the line and the conductor rod and the detection clamp mechanism, making the test more accurate and efficient, and improving the flexibility and adaptability of the device.

[0019] Secondly, when the driving motor rotates forward, the active gear synchronously drives the two synchronous gears to rotate, so that the adjusting rod can drive the positioning rod to move forward through the threaded hole of the rod body thread, thereby pushing the detection clamp mechanism out of the protective shell. When the detection clamp mechanism is pushed out of the protective shell, the control slide bars of the left clamp and the right clamp can shrink and close along the "eight"-shaped control groove to achieve clamping and fixing of the line or conductor rod. When the driving motor reverses, the adjusting rod also reverses, so that the detection clamp mechanism shrinks and resets to the inside of the protective shell. At the same time, the control slide bars of the left clamp and the right clamp automatically open under the control of the "eight"-shaped control groove to release the clamping of the line and the conductor rod. It is easy to install and disassemble, flexible to use, and the detection efficiency is greatly improved, thereby improving the flexibility and practicality of the device.

[0020] Furthermore, the track groove can limit the moving trajectory of the positioning rod through the track block, and the cooperation with the control groove can prevent the detection clamp mechanism from being skewed or twisted during movement, which may cause the device to get stuck. It is stable to use and improves the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

This design makes it possible that when the driving motor 5 rotates, the driving gear 501 synchronously drives the two synchronous gears 401 to rotate, so that the rotation rate of the adjusting rod 4 is the same, so that the two adjusting rods 4 can stably drive the track block 3031 to move forward and backward through the rod body thread; the driving motor 5 is fixed to the inside of the protective shell 2 by screwing, and the driving motor 5 is electrically connected to the external power supply and the control device.

The left clamp 301 is located at the top of the clamp body of the right clamp 302, so that when the device detects a higher line or conductor rod, it can control the protective shell 2 to move to the line or conductor rod through the telescopic extension rod 1, and then the detection clamp mechanism 3 can automatically extend out of the protective shell 2 driven by the drive motor 5 and clamp on the line or conductor rod.

[0037] Among them, the clamp body shape of the left clamp 301 and the right clamp 302 is an "L"-shaped design, and the left clamp 301 and the right clamp 302 are symmetrically designed. The detection clamp mechanism 3 is provided with two upper and lower clamps. The left clamp 301 and the right clamp 302 can stably clamp in an offset manner, and can adapt to the clamping contact detection of lines and conductor rods of different thicknesses. The "L"-shaped design of the left clamp 301 and the right clamp 302 allows the left clamp 301 and the right clamp 302 to be hung on the line or the conductor rod after clamping, thereby increasing the contact area between the line and the conductor rod and the detection clamp mechanism 3, making the test more accurate and efficient, and improving the flexibility and adaptability of the device.

[0038] Among them, a control slide bar 3012 is provided at one end of the clamp body of the left clamp 301 and the right clamp 302, and the control slide bar 3012 is symmetrical with the vertical rod of the corresponding clamp body of the detection clamp mechanism 3, the control slide bar 3012 and the clamp body of the detection clamp mechanism 3 are respectively located on both sides of the positioning hole 3011, and two groups of control grooves 202 are provided inside the protective shell 2, and the two groups of control grooves 202 are respectively arranged at the top and bottom of the protective shell 2, each group of control grooves 202 is provided with two symmetrical groove bodies, and the direction of the two groove bodies of each group of control grooves 202 is an "eight" shape, and the top and bottom rod bodies of the control slide bar 3012 are respectively inserted into the control grooves 202 at the top and bottom of the protective shell 2, and this design makes the positioning rod 303 move forward When moving, the detection clamp mechanism 3 is pushed out of the protective shell 2. When the detection clamp mechanism 3 is pushed out of the protective shell 2, the control slide bar 3012 of the left clamp 301 and the right clamp 302 can shrink and close along the "eight"-shaped control groove 202 to achieve clamping and fixing of the line or conductor rod. When the positioning rod 303 moves backward, the detection clamp mechanism 3 shrinks and resets to the inside of the protective shell 2. At the same time, the control slide bar 3012 of the left clamp 301 and the right clamp 302 automatically opens under the control of the "eight"-shaped control groove 202 to release the clamping of the line and the conductor rod. The device is easy to install and disassemble, flexible to use, and the detection efficiency is greatly improved, thereby improving the flexibility and practicality of the device.

[0039] Among them, a threaded hole 3032 is provided inside the block body of the track block 3031, and a thread is provided on the outside of the middle rod body of the adjusting rod 4. The adjusting rod 4 is screwed into the threaded hole 3032 of the track block 3031 through the rod body thread. This design enables the rod body thread to drive the positioning rod 303 to move forward and backward through the threaded hole 3032 when the adjusting rod 4 rotates.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In the present invention, when the detection line or conductor rod of the lightning protection device is at a higher position, the detection personnel can control the protective shell 2 to move to the line or conductor rod position by holding the telescopic extension rod 1, and then the detection clamp mechanism 3 can automatically extend out of the protective shell 2 and clamp on the line or conductor rod under the drive of the drive motor 5, so that the performance of the lightning protection device can be detected by detecting the line or conductor rod of the lightning protection device, and the drive motor 5 is rotated forward by the control device. When the drive motor 5 rotates forward, the active gear 501 synchronously drives the two synchronous gears 401 to rotate, so that the adjustment rod 4 can drive the positioning rod 303 to move forward through the rod body thread through the threaded hole 3032, and the track groove 201 can limit the movement trajectory of the positioning rod 303 through the track block 3031. The cooperation with the control groove 202 can prevent the detection clamp mechanism 3 from being skewed or twisted during movement, which may cause the device to be stuck, and the use is stable, so that the detection clamp mechanism 3 is pushed out of the protective shell 2. When the detection clamp mechanism 3 is pushed out of the protective shell 2, the left clamp 301 and The control slide bar 3012 of the right clamp 302 can be retracted and closed along the "eight"-shaped control groove 202 to achieve clamping and fixing of the line or conductor rod.

When the drive motor 5 reverses, the adjustment rod 4 also reverses so that the detection clamp mechanism 3 shrinks and resets to the inside of the protective shell 2. At the same time, the control slide bars 3012 of the left clamp 301 and the right clamp 302 are automatically opened under the control of the "eight"-shaped control groove 202, releasing the clamping of the circuit and the conductor rod. It is easy to install and disassemble, flexible to use, and the detection efficiency is greatly improved.
