Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment detection, and particularly relates to an electrical equipment detection device. Background Art

[0002] When an electrical equipment is in use, it needs to be pre - run before use and regularly maintained, etc. All these require the use of a detection device to detect the electrical parameters in the electrical equipment to ensure that its various parameters meet the design operation requirements and ensure its operation reliability.

[0003] After retrieval, a patent with the Chinese patent publication number CN208537583U discloses a portable electrical equipment detection device, including a telescopic plate, a positioning plate, a first support block and a second support block. A fixed joint is provided at the upper end of the telescopic plate. A protective sleeve is wrapped around the outer side of the connecting rod. The fixed frame body is fixedly connected to the telescopic plate through a fixing bolt, and the inner side of the fixed frame body is in mutual fitting connection with the detection instrument. The positioning plate is connected to the guide block through a locking knob. A first protective pad is pasted on one end of the positioning plate, and a second protective pad is pasted at the corner of the positioning plate. The first support block is fixed to the bottom of the fixed frame body, and the second support block is fixed to another telescopic plate.

[0004] The above - mentioned patent has the following deficiencies: When fixing the detection instrument, it needs to be carried out step by step manually, which is rather troublesome and loses the convenience of taking and placing the detection instrument.

[0005] Therefore, an electrical equipment detection device is proposed. Summary of the Invention

[0006] In view of this, the embodiments of the present invention hope to provide an electrical equipment detection device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the embodiments of the present invention is realized as follows: An electrical equipment detection device includes a box body and a detection instrument that is clamped and fixed inside the box body by a fixed arm and is used to detect electrical equipment. The fixed arm includes a folding cylinder fixed to the box body, a side piston and a linkage piston that are respectively slidably fitted at two points of the folding cylinder. The outer wall of the side piston is connected to a side clamping plate through a first piston rod. The top outer wall of the linkage piston is connected to a support plate through a second piston rod. The inner cavity of the folding cylinder is filled with a pressure transmission medium, and the pressure transmission medium is an inert gas. The two side ends of the folding cylinder are respectively fixedly installed with a first cylinder head and a second cylinder head. The first piston rod is slidably connected to the first cylinder head, the second piston rod is slidably connected to the second cylinder head, and a return spring is fixedly installed at the bottom of the linkage piston.

[0008] In some embodiments, an adsorption cylinder is fixedly embedded in the inner wall of the support plate, and a vacuum suction head communicated with its inner cavity is fixedly installed at the top of the adsorption cylinder.

[0009] In some embodiments, an adsorption piston is used in cooperation with the inner wall of the adsorption cylinder, and the adsorption piston is fixed to the outer wall of the top of the cylinder head II through a piston rod III.

[0010] In some embodiments, exhaust holes are formed in the inner wall of the adsorption cylinder.

[0011] In some embodiments, handle members are arranged on both sides of the box body. The handle members include a rotating shaft rotatably connected to the side wall of the box body and a handle fixed to the outer wall of the rotating shaft. A torsion spring is fixedly installed on the outer wall of the opposite side of the handle and the box body.

[0012] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0013] 1. For an electrical equipment detection device, on the one hand, it is only necessary to place the detection instrument on the support plate to achieve automatic clamping and fixing, which is relatively convenient. On the other hand, when the detection instrument is heavier, the pressure on the support plate is greater, so that the side clamping plate has a greater clamping force on the side of the detection instrument, realizing adaptive adjustment of the clamping force and ensuring the reliability of clamping and fixing.

[0014] 2. For an electrical equipment detection device, on the one hand, nitrogen gas is compressible as a gas, so that the whole pressure transmission is a flexible transmission, with a certain buffering effect, thus preventing the side clamping plate from hitting the side wall of the detection instrument and causing damage. On the other hand, the pressure transmission between the side piston and the linkage piston can compress nitrogen gas, preventing the side clamping plate from separating from the side wall of the detection instrument when the detection instrument vibrates up and down during the carrying process. Finally, nitrogen gas is an inert gas, which is relatively stable and non-combustible and non-supporting combustion, with high safety.

[0015] 3. For an electrical equipment detection device, when the detection instrument is placed on the top of the support plate and fits with the vacuum suction head, at this time the support plate descends, and the adsorption piston slides upward relative to the adsorption cylinder. In the early stage, the gas in the inner cavity of the adsorption cylinder is discharged through the exhaust hole. Subsequently, the adsorption piston moves above the exhaust hole, and the gas is discharged along the joint between the vacuum suction head and the detection instrument. In the final stage, the detection instrument presses the vacuum suction head to axial deformation, so as to adsorb the bottom of the detection instrument through negative pressure, realizing further fixing reliability. In addition, when it is necessary to take away the detection instrument, it is only necessary to lift the detection instrument upward. When the adsorption piston moves to the exhaust hole, the inner cavity of the adsorption cylinder is communicated with the outside world, and the adsorption effect can be released, which is relatively convenient.

[0016] The above summary is for the purpose of the specification only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will be readily apparent by reference to the drawings and the following detailed description.

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] As Figures 1-3As shown in the figure, an electrical equipment detection device includes a box body 1 and a detection instrument 2 that is clamped and fixed inside the box body 1 by a fixed arm 3 and is used to detect electrical equipment. The fixed arm 3 includes a folding cylinder 4 fixed to the box body 1 and a side piston 5 and a linkage piston 12 that are respectively slidably fitted to two points of the folding cylinder 4. The outer wall of the side piston 5 is connected to a side clamping plate 8 through a first piston rod 6. The top outer wall of the linkage piston 12 is connected to a support plate 9 through a second piston rod 10. The inner cavity of the folding cylinder 4 is filled with a pressure transmission medium. When this device is in use, the detection instrument 2 can be directly placed on the top of the support plate 9. The support plate 9 descends due to the pressure generated by the gravity of the detection instrument 2, and then is transmitted to the side piston 5 through the pressure transmission medium in the inner cavity of the folding cylinder 4, thereby driving the side clamping plate 8 to extend towards the detection instrument 2 and clamping and fixing it. On the one hand, in this device, only by placing the detection instrument 2 on the support plate 9 can automatic clamping and fixing be achieved, which is relatively convenient. On the other hand, the heavier the detection instrument 2 is, the greater the pressure it exerts on the support plate 9, so that the side clamping plate 8 has a greater clamping force on the side of the detection instrument 2, realizing adaptive adjustment of the clamping force and ensuring the reliability of clamping and fixing.

[0033] In this embodiment, the specific type of the pressure transmission medium is not limited and can be hydraulic oil, air or inert gas. Preferably, the pressure transmission medium is nitrogen. On the one hand, nitrogen as a gas has compressibility, so that the entire pressure transmission is a flexible transmission, with a certain buffering effect, thereby preventing the side clamping plate 8 from hitting the side wall of the detection instrument 2 and causing damage. On the other hand, the pressure transmission between the side piston 5 and the linkage piston 12 can compress nitrogen, preventing the side clamping plate 8 from separating from the side wall of the detection instrument 2 when the detection instrument 2 vibrates up and down during the carrying process. Finally, nitrogen as an inert gas is relatively stable and non-combustible and non-supportive of combustion, with high safety.

[0034] In this embodiment, the two ends of the folding cylinder 4 are respectively fixed with a first cylinder head 7 and a second cylinder head 11 through bolts. The first piston rod 6 is slidably connected to the first cylinder head 7, and the second piston rod 10 is slidably connected to the second cylinder head 11. By setting the first cylinder head 7 and the second cylinder head 11, which are respectively slidably fitted with the first piston rod 6 and the second piston rod 10, it can play a guiding role in the movement of the side clamping plate 8 and the support plate 9, preventing deformation and leakage in the cooperation between the side piston 5, the linkage piston 12 and the folding cylinder 4.

[0035] In this embodiment, a return spring 13 is fixedly installed at the bottom of the linkage piston 12. The return spring 13 can apply a return force to the linkage piston 12 through its elastic force to ensure that when the detection instrument 2 is taken out, the support plate 9 rises to the topmost position.

[0036] In this embodiment, a support rubber foot 14 is welded to the bottom outer wall of the folding cylinder 4.

[0037] In this embodiment: When in use, the detection instrument 2 can be directly placed on the top of the support plate 9. The pressure generated by the gravity of the detection instrument 2 on the support plate 9 decreases, and then is transmitted to the side piston 5 through the pressure transmission medium in the cavity of the folding cylinder 4, thereby driving the side clamping plate 8 to extend towards the detection instrument 2 and clamping and fixing it. By providing the cylinder head 7 and the cylinder head 11, which are respectively in sliding fit with the piston rod 6 and the piston rod 10, it can play a guiding role in the movement of the side clamping plate 8 and the support plate 9. The return spring 13 can apply a return force to the linkage piston 12 through its elastic force to ensure that when the detection instrument 2 is taken out, the support plate 9 rises to the topmost position.

[0038] Embodiment 2:

[0039] An electrical equipment detection device. In this embodiment, the following improvements are made on the basis of Embodiment 1, as Figure 3 shown, an adsorption cylinder 17 is fixedly embedded in the inner wall of the support plate 9, and a vacuum suction head 18 communicated with its inner cavity is fixedly bolted to the top of the adsorption cylinder 17.

[0040] In this embodiment, an adsorption piston 19 is used in cooperation with the inner wall of the adsorption cylinder 17, and the adsorption piston 19 is fixed to the outer wall of the top of the cylinder head 11 through a piston rod 15.

[0041] In this embodiment, an exhaust hole 16 is opened in the inner wall of the adsorption cylinder 17.

[0042] In this embodiment: When the detection instrument 2 is placed on the top of the support plate 9 and fits with the vacuum suction head 18, at this time the support plate 9 descends, and the adsorption piston 19 slides upward relative to the adsorption cylinder 17. In the early stage, the gas in the inner cavity of the adsorption cylinder 17 is discharged through the exhaust hole 16. Subsequently, the adsorption piston 19 moves above the exhaust hole 16, and the gas is discharged along the joint between the vacuum suction head 18 and the detection instrument 2. In the final stage, the detection instrument 2 presses the vacuum suction head 18 to axially deform, thereby adsorbing the bottom of the detection instrument 2 through negative pressure to achieve further fixing reliability. In addition, when the detection instrument 2 needs to be taken away, only need to lift the detection instrument 2 upward. When the adsorption piston 19 is displaced to the exhaust hole 16, the inner cavity of the adsorption cylinder 17 is communicated with the outside world, and the adsorption effect can be released, which is more convenient.

[0043] Embodiment 3:

[0044] An electrical equipment detection device. In this embodiment, the following improvements are made on the basis of Embodiments 1 and 2, as Figures 4-5 shown, handle parts 20 are provided on both sides of the box body 1. The handle parts 20 include a rotating shaft 21 rotatably connected to the side wall of the box body 1 and a handle 22 fixed to the outer wall of the rotating shaft 21. A torsion spring 23 is welded to the outer wall of the opposite side of the handle 22 and the box body 1.

[0045] In this embodiment, when it is necessary to carry and move, rotate the two handles 22 to the upper side, and then it can be carried by hand. When it is necessary to use, release the handle 22, and it will rotate to both sides under the torsion action of the torsion spring 23 to be in a storage state, and then the detection operation can be carried out, which is relatively convenient.

[0046] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
