Description

Technical Field

[0001] The invention belongs to the technical field of insulation detection of electrical equipment, in particular to an insulation detection device for an electrical tool. Background Art

[0002] The electrical tool insulation detection device is an important tool for real-time monitoring of the surface insulation of electrical equipment, which is of great significance for ensuring the normal operation and safety of the equipment.

[0003] The existing electrical tool insulation detection device still has disadvantages in actual use: when a handheld insulation tester is used to detect the insulation of internal parts of electrical equipment, due to the large number of parts inside the electrical cabinet and the large number of wires used to connect the parts, when distributing the wires, for the convenience of installation, the arrangement of the wires does not appear regular and orderly. Some wires are even arranged on the outside of the parts, covering the parts. At this time, when the insulation of the internal parts of the electrical equipment is detected, the insulation of the parts to be detected also includes the insulation of the wires, which leads to errors in the insulation detection of the internal parts of the electrical equipment. It will then be necessary to pull the wires arranged outside the parts apart to expose the parts for accurate insulation detection of the parts. Therefore, an electrical tool insulation detection device is proposed. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides an electrical tool insulation detection device, including an insulation detection instrument body and a housing, and also includes:

[0005] A support member, wherein the support member is sleeved on the outer wall of the shell;

[0010] Preferably, the support member comprises a positioning ring, the positioning ring is fixedly sleeved on the outer wall of the shell, four brackets are annularly mounted at equal angles on one side of the positioning ring close to the rotating member, and one end of the bracket away from the positioning ring is fixedly connected to the support ring.

[0011] Preferably, two arc-shaped grooves are symmetrically provided on the circumference of the rotating plate, the arc-shaped grooves are made of rubber, and the rotating plate is transparent.

[0012] Preferably, the outer shape of the stop block is trapezoidal, and inclined surfaces are provided on both sides. Two stop blocks are arranged in an annular shape at equal angles and are both located on the inner side of the clamping plate.

[0013] Preferably, there are two groups of card plates symmetrically arranged and both are located on the outside of the stop block. A semicircular groove is provided at one end of the card plate away from the rotating plate. The inner wall of the semicircular groove is made of rubber. The semicircular groove is clamped with the cylinder. When the rotating plate rotates, the card plate will be driven to rotate synchronously. When the card plate rotates to the position of the cylinder, the semicircular groove of the card plate will be clamped on the outer wall of the cylinder as the rotating plate moves.

[0014] Preferably, the pillar is elastically connected to the rotating plate through a first spring, the end of the pillar close to the support ring is spherical, and the end of the pillar away from the support ring is truncated cone-shaped. The spherical shape of the contact end of the pillar and the support ring facilitates the contact between the pillar and the protrusion. At the same time, the truncated cone-shaped design of the end of the pillar away from the support ring, when the pillar moves to the outside of the electrical equipment parts covered with wires, the truncated cone-shaped design of the pillar will make it easier to separate two adjacent wires, thereby facilitating the insulation detection of the electrical equipment.

[0015] Preferably, a cylinder is installed on the outer wall of the protrusion, the outer wall of the cylinder is made of rubber material, and the cylinder is movably clamped in the semicircular groove of the clamping plate.

[0016] Preferably, two protrusions are symmetrically arranged and are fixed to one side of the support ring close to the movable module. One side of the protrusion, the support ring and the slope are all in contact with the pillar. One end of the pillar will slide to the top of the support ring through the protrusion and the slope. Conversely, one end of the pillar will slide to the top surface of the protrusion through the support ring and the slope.

[0017] Preferably, a detection module is installed inside the shell, and a resistance component is installed at one end of the detection module located inside the shell. The end of the detection module away from the insulation tester body extends to the outside of the shell, and one end of the detection module is located on the outside of the shell.

[0018] Preferably, the abutment assembly comprises a moving rod, the moving rod is elastically connected to the housing via a spring telescopic cylinder, and one end of the moving rod is abuttingly connected to the abutment block;

[0019] When the rotating plate is driven by an external force to rotate the abutment block in the same direction, the end of the moving rod will fit onto the side wall of the rotating plate along the inclined surface of the abutment block.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention arranges the cooperation of structures such as rotating parts and moving components, thereby expanding the wires arranged on the outside of the parts to be inspected and exposing them, so as to facilitate the accuracy of subsequent insulation detection of the parts to be inspected. Two pillars are placed in a vertical straight line in the middle area of ​​two adjacent wires. The rotating plate drives one end of the pillar to move along the outer wall of the slope to the side wall of the protrusion away from the support ring. The pillar will extend to the side away from the fixed component. The rotation of the rotating plate causes the two pillars to expand the two adjacent wires in opposite directions, so that the parts to be inspected are exposed to the outside, thereby facilitating the insulation detection of the parts to be inspected.

[0022] The present invention cooperates with structures such as a resistance component and a detection module, so that when faced with complex and difficult-to-detect parts, internal parts of electrical equipment can be smoothly detected. When the rotating plate rotates, the resistance block drives the resistance block to rotate. The resistance block will initially release the resistance effect on the moving rod. The moving rod is subjected to the elastic force of the spring telescopic tube, so that the end of the moving rod close to the resistance block is attached to the rotating plate along the inclined surface of the resistance block. The outward extension of the moving rod will drive the detection module to extend outward in the same direction. The detection module will extend outward from the inside of the shell and make it close to the part to be detected in the middle area of ​​the wire after it is supported by two pillars, so as to realize the insulation detection of the part to be detected.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, the present invention provides an electrical tool insulation detection device, including an insulation detection instrument body 1 and a housing 2, and also includes:

[0035] A support member 3, wherein the support member 3 is sleeved on the outer wall of the housing 2;

[0036] The movable module 4 is movably sleeved on a side of the outer wall of the shell 2 away from the insulation tester body 1;

[0037] A fixing assembly 5, the fixing assembly 5 is fixedly connected to the supporting member 3 and is in contact with the movable module 4;

[0038] The movable module 4 includes a rotating member 41, and a moving assembly 42 symmetrically sleeved inside the rotating member 41. The rotating member 41 includes a rotating plate 411. A stop block 412 and a clamping plate 413 are respectively installed on a side wall of the rotating plate 411 close to the housing 2. The moving assembly 42 includes a pillar 421.

[0039] The fixing assembly 5 includes a support ring 52 . A protrusion 51 is installed on a side wall of the support ring 52 close to the rotating plate 411 . Slopes 54 are respectively formed on two sides of the protrusion 51 .

[0040] like Figure 3 As shown, the support member 3 includes a positioning ring 31, which is fixedly sleeved on the outer wall of the shell 2, and four brackets 32 are installed in a circular shape at equal angles on one side of the positioning ring 31 close to the rotating member 41, and one end of the bracket 32 ​​away from the positioning ring 31 is fixedly connected to the support ring 52.

[0041] like Figures 3 to 5As shown, two arc grooves are symmetrically provided on the circumference of the rotating plate 411 , the arc grooves are made of rubber, and the rotating plate 411 is transparent.

[0042] By adopting the above solution, the rotating plate 411 can be rotated through the arc groove so that the rotating plate 411 drives the support 421 to reach a suitable position, and then the insulation test is performed. The transparent design of the rotating plate 411 makes it more convenient for personnel to observe.

[0043] like Figure 4 As shown, the outer shape of the stop block 412 is trapezoidal, and inclined surfaces are provided on both sides. Two stop blocks 412 are arranged in a ring at equal angles and are both located on the inner side of the clamping plate 413 .

[0044] By adopting the above solution, the trapezoidal design of the stop block 412 and the inclined surfaces on both sides enable the abutment component 7 to move from the side wall of the rotating plate 411 along the inclined surface of the stop block 412 to the end point of the stop block 412 .

[0045] like Figure 4 As shown, two groups of clamping plates 413 are symmetrically arranged and are both located on the outside of the stop block 412 . A semicircular groove is opened at one end of the clamping plate 413 away from the rotating plate 411 . The inner wall of the semicircular groove is made of rubber and is clamped with the cylinder 53 .

[0046] By adopting the above solution, when the rotating plate 411 rotates, the clamping plate 413 will be driven to rotate synchronously. When the clamping plate 413 rotates to the position of the cylinder 53, the semicircular notch of the clamping plate 413 will be clamped on the outer wall of the cylinder 53 as the rotating plate 411 moves, thereby achieving fixation between the two.

[0047] like Figure 4 As shown, the support 421 is elastically connected to the rotating plate 411 through a first spring 422 , and one end of the support 421 close to the support ring 52 is spherical, and one end of the support 421 away from the support ring 52 is truncated cone-shaped.

[0048] Adopt the above solution: Combine Figure 3 and Figure 4 It is concluded that the spherical shape of the contact end of the support 421 and the support ring 52 facilitates the contact between the support 421 and the protrusion 51. At the same time, the truncated cone design of the end of the support 421 away from the support ring 52, when the support 421 moves to the outside of the electrical equipment parts covered with wires, the truncated cone design of the support 421 will make it easier to separate two adjacent wires, thereby facilitating the insulation detection of the electrical equipment.

[0049] like Figure 3 , Figures 5 to 7 As shown, a cylinder 53 is installed on the outer wall of the protrusion 51 . The outer wall of the cylinder 53 is made of rubber material. The cylinder 53 is movably clamped in the semicircular groove of the clamping plate 413 .

[0050] With the above solution, due to the rubber material of the cylinder 53, when the cylinder 53 is engaged with the semicircular notch of the clamping plate 413, the two can achieve a clamping and fixing effect.

[0051] like Figure 7 As shown, two protrusions 51 are symmetrically arranged and are both fixed to a side of the support ring 52 close to the movable module 4 . One side of the protrusion 51 , the support ring 52 and the slope 54 are all in contact with the support 421 .

[0052] With the above solution, when the rotating plate 411 rotates to drive the pillar 421 to rotate synchronously, one end of the pillar 421 will slide to the top of the support ring 52 through the protrusion 51 and the slope 54. Conversely, one end of the pillar 421 will slide to the top surface of the protrusion 51 through the support ring 52 and the slope 54.

[0053] like Figure 2 , Figure 3 and Figure 5 As shown, a detection module 6 is installed inside the shell 2 , and an abutment assembly 7 is installed at one end of the detection module 6 located inside the shell 2 . One end of the detection module 6 away from the insulation tester body 1 extends to the outside of the shell 2 .

[0054] Adopt the above scheme: according to Figure 2 It can be seen that one end of the detection module 6 is located outside the housing 2. Even when the detection module 6 is not extended, the one end of the detection module 6 can smoothly perform insulation detection on the internal parts of the electrical equipment.

[0055] like Figure 2 and Figure 5 As shown, the abutment assembly 7 includes a moving rod 71, the moving rod 71 is elastically connected to the housing 2 via a spring telescopic cylinder 72, and one end of the moving rod 71 is abutted and connected to the abutment block 412;

[0056] When the rotating plate 411 is driven by an external force to rotate the stop block 412 in the same direction, the end of the moving rod 71 will be attached to the side wall of the rotating plate 411 along the inclined surface of the stop block 412 .

[0057] The working principle and use process of the present invention:

[0058] First, when testing the internal parts of electrical equipment, if the outside of the parts is not covered by wires, the insulation tester body 1 can be directly held and the detection module 6 can be aimed at the outside of the part to be tested to obtain the insulation value;

[0059] Secondly, when the outside of the part to be inspected is covered with wires, the two pillars 421 are placed in a vertical straight line in the middle of two adjacent wires, and then the rotating plate 411 is rotated to drive the pillars 421 to rotate in the same direction. The end of the pillar 421 close to the support ring 52 will gradually move along the outer wall of the slope 54 to the side wall of the protrusion 51 away from the support ring 52. At this time, the pillar 421 will extend outward to the side away from the fixed component 5. With the rotation of the rotating plate 411, the two pillars 421 will move away from the two adjacent wires. The two pillars 421 will open the two adjacent wires, so that the part to be inspected is exposed to the outside;

[0060] Subsequently, when the rotating plate 411 rotates, it will also synchronously drive the stop block 412 to rotate. The stop block 412 will initially release the resistance effect on the moving rod 71. At this time, the moving rod 71 is elastically acted upon by the spring telescopic tube 72, so that the end of the moving rod 71 close to the stop block 412 will fit on the rotating plate 411 along the inclined surface of the stop block 412. The moving rod 71 will drive the detection module 6 to extend outward in the same direction. At this time, the detection module 6 will pass through the middle area of ​​the wire after the two pillars 421 are stretched open and approach the part to be detected, so as to realize the insulation detection of the part to be detected.

[0061] To sum up, when there is no wire arranged on the outside of the part to be detected inside the electrical equipment, the device can perform normal detection. When there is a wire arranged on the outside of the part to be detected, the device can first use the rotating plate 411 to drive the pillar 421 to rotate in the same direction, and then use the two pillars 421 to make the two adjacent wires move in opposite directions. The two pillars 421 support the two adjacent wires to expose the part to be detected. Then, when the rotating plate 411 rotates, the block 412 releases the resistance to the moving rod 71. The moving rod 71 is subjected to the elastic force of the spring telescopic tube 72, so that the moving rod 71 fits on the rotating plate 411 and drives the detection module 6 to extend outward in the same direction, and then performs detection, thereby avoiding the increase of heat caused by the wire covering the part, thereby affecting the detection effect. The operation is convenient and efficient.
