Description

Technical Field

[0001] The present invention belongs to the field of nuclear power maintenance tooling equipment, and in particular relates to a detection device. Background Art

[0002] Currently, with the rapid development of modular integration technology in industrial applications, more and more control systems are adopting modular integration systems to collect input and output points, thereby improving the automation level of control systems. During the inspection and maintenance of modular integration systems, it is often necessary to check whether the fuse tube is functioning properly. Generally, this is done by using a multimeter to test the conductivity of the fuse tube ends.

[0003] However, this method can only test a single fuse, resulting in low efficiency and unstable contact between the multimeter's electrical contacts and the fuse, leading to inaccurate test results. Furthermore, fuses are small, making them prone to dropping or loss during individual testing due to improper handling.

[0004] Therefore, a rapid detection device for fuse tubes is needed to complete the detection of fuse tubes in batches, quickly, safely and accurately. Summary of the Invention

[0005] The purpose of the present invention is to provide a detection device, aiming to solve the problem of how to quickly and safely perform accurate detection on a fuse tube.

[0006] The present invention provides a detection device connected to a test power supply to detect a fuse tube, the detection device comprising:

[0007] A housing structure comprising a test box and a plurality of test sleeves connected to the test box and made of insulating material and each housing a fuse tube, wherein the test box has a test cavity and a surface of the test box has a plurality of test holes connected to the test cavity and corresponding to each of the test sleeves, one end of the test sleeve is inserted into the test cavity through the corresponding test hole, and the other end of the test sleeve is connected to the test box at the test hole; and

[0008] An electrode structure is made of a conductive material and is connected to the test set. The electrode structure is used to electrically connect the fuse tube to the test power supply. The electrode structure includes a first electrode arranged at one end of the test set and electrically connected to one end of the fuse tube, and a second electrode connected to the other end of the test set and electrically connected to the other end of the fuse tube. The first electrode and the second electrode are respectively electrically connected to two electrodes of the test power supply.

[0009] The technical effect of the present invention is as follows: by placing the fuse tube in the test sleeve, the test sleeve can effectively fix the fuse tube, making it difficult to fall or lose. Then, the electrode structure is connected to both ends of the fuse tube, and the electrode structure is also electrically connected to both ends of the test power supply, so that the fuse tube can be accurately and safely measured. Multiple fuse sleeves further enable batch testing of fuse tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figures 1 to 3 , an embodiment of the present invention provides a detection device 100, which is used to cooperate with a test power supply to detect a fuse tube 50. Specifically, the fuse tube 50 is cylindrical, and conductive ends are provided at both ends thereof. Furthermore, the material of the conductive end is a conductive metal material and can be magnetically attracted to the magnet 422, such as iron. Optionally, the test power supply is a DC power supply. The detection device 100 includes: a shell structure 101 and an electrode structure 49. The shell structure 101 includes a test box 10 and a plurality of test sleeves 20, each of which is connected to the test box 10 and is made of an insulating material and each accommodates a fuse tube 50. Optionally, the test sleeve 20 is used to fix the fuse tube 50, and its material can be a plastic material. A test cavity 111 is provided inside the test box 10, and a plurality of test holes 112 are provided on the surface of the test box 10, which are connected to the test cavity 111 and are respectively provided corresponding to each test sleeve 20. One end of the test sleeve 20 is inserted into the test cavity 111 through the corresponding test hole 112, and the other end of the test sleeve 20 is connected to the test box 10 at the test hole 112. The electrode structure 49 is made of a conductive material and is connected to the test sleeve 20. The electrode structure 49 is used to electrically connect the fuse tube 50 to the test power supply. The electrode structure 49 includes a first electrode 40 disposed at one end of the test sleeve 20 and electrically connected to one end of the fuse tube 50, and a second electrode 42 connected to the other end of the test sleeve 20 and electrically connected to the other end of the fuse tube 50. The first electrode 40 and the second electrode 42 are respectively electrically connected to the two electrodes of the test power supply.

[0023] See also Figures 4 to 7 By placing the fuse tube 50 in the test sleeve 20, the test sleeve 20 can effectively fix the fuse tube 50, making it not easy to fall or be lost. Then the electrode structure 49 is connected to both ends of the fuse tube 50, and the electrode structure 49 is also electrically connected to both ends of the test power supply, so that the fuse tube 50 can be accurately and safely measured. Multiple fuse sleeves further enable batch testing of the fuse tube 50.

[0024] Optionally, the length of the fuse tube 50 is slightly greater than the depth of the test sleeve 20, so that a portion of the fuse tube 50 extends out of the test sleeve 20, facilitating quick insertion and removal and saving working time. Alternatively, the fuse tube 50 can be quickly inserted and removed with the help of professional tools.

[0025] In one embodiment, the first electrode 40 includes an electrode sheet 41 connected to the inner wall of the test sleeve 20 and abutting the fuse tube 50. It is understood that one end of the electrode sheet 41 is connected to the test power supply through a wire to connect the conductive end of the fuse tube 50 to an electrode of the test power supply.

[0026] In one embodiment, the test sleeve 20 defines a conductive slot 22 extending axially along the test sleeve 20, and a conductive opening 23 extending through the inner wall of the test sleeve 20 is defined. The electrode sheet 41 is disposed within the conductive slot 22 and abuts against the fuse tube 50 through the conductive opening 23. The conductive slot 22 extends to the edge of the sleeve opening at one end of the test sleeve 20, and the electrode sheet 41 is inserted into the conductive slot 22 through the slot, making assembly of the electrode sheet 41 simple and convenient.

[0027] In one embodiment, the electrode sheet 41 includes a conductive spring 412 with elastic restoring force and fixed arms 411 respectively connected to the two ends of the conductive spring 412. The two fixed arms 411 are respectively clamped at the two ends of the conductive slot 22. The extension path of the conductive spring 412 is arranged in an arc shape, and its raised portion passes through the conductive opening 23 and elastically abuts the fuse tube 50. Specifically, one of the two fixed arms 411 is connected to an electrode of the test power supply via a wire. The conductive spring 412 abuts the fuse tube 50 and the edge of the conductive opening 23 at the same time, and then the two fixed arms 411 are pressed against the groove wall of the guide groove, so that the electrode sheet 41 is adaptively fixed in the guide groove, improving the stability of the electrical connection between the electrode sheet 41 and the fuse tube 50, and facilitating the installation and removal of the electrode sheet 41.

[0028] In one embodiment, two electrode sheets 41 are symmetrically provided. The two conductive springs 412 elastically abut against the fuse tube 50, thereby clamping and securing the fuse tube 50. Optionally, more than two electrode sheets 41 may be provided, and the test sleeve 20 is provided with a conductive slot 22 and a conductive port 23 at a position corresponding to each electrode sheet 41.

[0029] In one embodiment, the second electrode 42 includes an electrode disk 421 disposed in the fuse tube 50 and electrically connected to the test power supply, with one end of the fuse tube 50 abutting against the electrode disk 421. The electrode disk 421 is electrically connected to another electrode of the test power supply via a wire.

[0030] See also Figures 5 to 7 In one embodiment, the second electrode 42 further includes a magnet 422 having an annular structure and generating a magnetic attraction between the fuse tube 50 and the electrode disk 421, and the electrode disk 421 is located inside the magnet 422. After the fuse tube 50 is inserted into the test set 20, due to the magnetic attraction, the magnet 422 can automatically adsorb the fuse tube 50 onto the electrode disk 421, without the need for manual adjustment and confirmation of whether it is plugged in place, thereby facilitating the electrical connection between the fuse tube 50 and the electrode disk 421, and maintaining the stability of the electrical connection of the fuse tube 50 during the test process. In particular, when the test set 20 is in a horizontal setting, the magnetic attraction can automatically adsorb the fuse tube 50 onto the electrode disk 421, thereby improving the convenience of assembling the fuse tube 50.

[0031] The test hole 112 also features multiple escape slots, spaced apart and extending one end through the surface of the test box 10. Each test sleeve 20 has multiple stoppers 21 protruding from its side surface, corresponding to the escape slots. Each stopper 21 snaps into its corresponding escape slot. Within each escape slot in the same test hole 112, at least one has a different width than the others, allowing the test sleeve 20 to be quickly aligned and inserted into the test hole 112.

[0032] In one embodiment, the detection device 100 further includes a circuit structure 30, which includes a circuit board 31 disposed within the test cavity 111 and a signal light 32 connected to the circuit board 31 and used to display the test results of the fuse tube 50. A signal light 32 is provided at intervals at each test hole 112. The circuit structure 30 also includes a manual switch, which can flexibly control the start and stop of the detection device 100. Optionally, when the signal light 32 displays green, it indicates that the corresponding fuse tube 50 is good; conversely, when the signal light 32 displays red, it indicates that the corresponding fuse tube 50 is bad. The signal light 32 allows for quick and intuitive reading of the condition of the fuse tube 50.

[0033] Optionally, the test box 10 includes a box body 11 having a test cavity 111 and a bottom cover 12 connected to the box body 11, and the circuit board 31 is disposed on the bottom cover 12. The box body 11 is provided with a wire hole 113 that connects to the test cavity 111 and allows wires to pass through.

[0034] In one embodiment, the circuit structure 30 further includes a display screen 33 connected to the test box 10 and corresponding to each test set 20 and used to display the resistance value of the corresponding fuse tube 50. The resistance value of each fuse tube 50 can be directly read through the display screen 33, which is highly intuitive.
