[0031] 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.

[0032] Example

[0033] like Figure 1-6As shown, a portable nondestructive testing device proposed in one embodiment of the present invention includes a portable case 1, a nondestructive testing instrument 2 is arranged inside the portable case 1, the portable case 1 is used to store and carry the nondestructive testing instrument 2, the nondestructive testing instrument 2 is used to detect whether there are defects or unevenness in the object to be tested, a dehumidification component is arranged in the portable case 1, and the dehumidification component is arranged in multiple numbers, the dehumidification component is used to remove moisture inside the portable case 1, and the dehumidification bag in the dehumidification component used for dehumidifying the inside of the portable case 1 can also be replaced regularly.

[0034] By setting the dehumidification component, not only can the inside of the portable box 1 be dehumidified, so that the non-destructive testing instrument 2 inside the portable box 1 is in a dry environment, thereby avoiding the normal use of the non-destructive testing instrument 2 due to the moisture inside the portable box 1, but also by regularly replacing the dehumidification bag inside the portable box 1, it can be avoided that the moisture inside the portable box 1 is increased due to forgetting to replace the dehumidification bag, thereby affecting the normal use of the non-destructive testing instrument 2.

[0035] like Figure 2-4 As shown, the dehumidification component includes a storage cylinder 3 fixedly arranged in a portable box 1, a top cover 30 is arranged at the top of the storage cylinder 3, a material discharge box 4 is arranged below the storage cylinder 3, the material discharge box 4 is arranged at the bottom end of the inner side of the portable box 1, a plurality of through openings 6 are opened on the material discharge box 4, a top block 5 is fixedly arranged at one end of the material discharge box 4, a turntable 7 is arranged between two connected dehumidification components, and the turntable 7 is rotatably connected to the portable box 1. Two connecting rods 8 are rotatably arranged on the turntable 7, and the two connecting rods 8 are arranged up and down, and the ends of the two connecting rods 8 away from the turntable 7 are rotatably connected to the two top blocks 5 respectively, and a servo motor 9 is arranged on one side of the turntable 7, and the servo motor 9 is fixedly arranged on the portable box 1, and the output end of the servo motor 9 passes through the portable box 1 and docks with the turntable 7. The portable case 1 is provided with a discharge port 10 , which corresponds to the position of the discharge port 10 and the discharge box 4 in the portable case 1 , and the size of the discharge port 10 is adapted to the size of the portable case 1 .

[0036] In this example: first, open the top cover 30 on the storage cylinder 3, and then put enough dehumidification bags into the storage cylinder 3, the dehumidification bags at the bottom inner side of the storage cylinder 3 will fall into the discharge box 4 below the storage cylinder 3, and the dehumidification bags in the discharge box 4 will absorb and eliminate the moisture inside the portable case 1. When the dehumidification bags in the discharge box 4 need to be replaced, start the servo motor 9. The start of the servo motor 9 drives the turntable 7 to rotate, and the rotation of the turntable 7 drives the connecting rod 8 thereon to move, and the connecting rod 8 drives the top block 5 to move. The movement of the top block 5 will push the discharge box 4 out of the discharge port 10. When the discharge box 4 is staggered with the storage cylinder 3, the top of the top block 5 will block the discharge of the discharge box 4. When the connecting rod 8 is rotated to ninety degrees, the discharge box 4 is completely The dehumidification bag in the discharge box 4 will fall into the discharge box 4, thereby completing the replacement of the dehumidification bag. The servo motor 9 restart time is set by the controller (based on the prior art, which will not be introduced in detail in the present invention), and the servo motor 9 is started in the reverse direction according to the above steps, so that the turntable 7 can be rotated one hundred and eighty degrees. The above steps can be repeated.

[0037] The provision of the through opening 6 improves the air flow between the dehumidification bag placed in the discharge box 4 and the storage space inside the portable case 1, thereby improving the dehumidification effect inside the portable case 1. The provision of the top block 5 can seal the discharge port of the storage cylinder 3, thereby preventing the dehumidification bag in the storage cylinder 3 from falling to the bottom end of the inner side of the portable case 1 by itself after the discharge box 4 and the storage cylinder 3 are offset, which will make it difficult for the dehumidification bag that falls to the bottom end of the inner side of the portable case 1 to be discharged from the portable case 1.

[0038] like Figure 5 and Figure 6 As shown, a slot 11 is provided on the lower end surface of the discharge box 4, a fixing plate 12 is fixedly provided on the portable box 1, the fixing plate 12 is located below the discharge port 10, an elastic paddle 13 is fixedly provided on the fixing plate 12, and the elastic paddle 13 corresponds to the slot 11 on the discharge box 4.

[0039] In this example: when the discharge box 4 extends out of the portable case 1 from the discharge port 10, the elastic paddle 13 will move along the slot 11 toward the dehumidification bag placed on the discharge box 4; when the elastic paddle 13 contacts the dehumidification bag, the force on the elastic paddle 13 is fully applied, and the discharge box 4 continues to move, so that the top of the elastic paddle 13 moves along the inner bottom end of the dehumidification bag; when the discharge box 4 moves to the end of its stroke and moves toward the portable case 1, the elastic paddle 13 will support the dehumidification bag on the discharge box 4, so that the dehumidification bag on the discharge box 4 will not move with the movement of the discharge box 4; when the discharge box 4 is retracted into the portable case 1, the dehumidification bag on the discharge box 4 extending out of the portable case 1 will fall to the ground; when the dehumidification bag falls to the ground, the elastic paddle 13 returns to its original position through its own elasticity.

[0040] By providing the fixing plate 12 and the elastic paddle 13, the dehumidification bag extending from the portable case 1 can be automatically removed, thereby making the automatic replacement of the dehumidification bag more intelligent.

[0041] like Figure 6 As shown, grooves are provided on the upper and lower side walls of the inner side of the discharge port 10, a sealing plate 14 is provided in the groove located at the upper inner side of the discharge port 10 through a hinge, and a first mounting groove is provided in the groove located at the lower inner side of the discharge port 10, in which a magnet 15 is fixedly provided. A second mounting groove is provided on the sealing plate 14, in which an iron sheet 16 is fixedly provided, and the positions of the iron sheet 16 and the magnet 15 correspond to each other.

[0042] In this example: when the discharge box 4 extends out of the portable case 1 from the discharge port 10, the sealing plate 14 at the discharge port 10 will be lifted up, and the lifted sealing plate 14 will rotate along the hinge. When the discharge box 4 extends from the discharge port 10 to the end of the stroke and returns, the sealing plate 14 rotates toward the portable case 1 due to its own weight as the discharge box 4 moves. When the discharge box 4 is moved into the portable case 1, the sealing plate 14 is adsorbed on the magnet 15 on the discharge port 10 through the iron sheet 16 thereon.

[0043] The arrangement of the magnet 15 and the iron sheet 16 can improve the sealing effect between the sealing plate 14 and the discharge port 10 , thereby reducing the influence of the external environment on the nondestructive testing instrument 2 in the portable box 1 .

[0044] like Figure 1 As shown, a protective shell 17 is fixedly arranged on the portable box 1, and the protective shell 17 is arranged to cover the outside of the servo motor 9. Ventilation and heat dissipation holes 18 are opened on the protective shell 17. The servo motor 9 is protected by the provision of the protective shell 17, and the provision of the ventilation and heat dissipation holes 18 facilitates ventilation and heat dissipation of the servo motor 9 located in the protective shell 17.

[0045] like Figure 3As shown, two limit plates 19 are fixedly arranged in the portable box 1, a first rubber pad 20 is arranged between the two limit plates 19, and the nondestructive testing instrument 2 is seated on the first rubber pad 20. A protective cover 21 is rotatably arranged on the portable box 1 through a hinge, and a second rubber pad 22 is fixedly arranged on the side wall of the protective cover 21 opposite to the portable box 1.

[0046] The setting of the limit plate 19 serves to limit the position of the nondestructive testing instrument 2, thereby preventing the nondestructive testing instrument 2 in the portable box 1 from shaking with the shaking of the portable box 1, which may easily cause damage to the nondestructive testing instrument 2. The setting of the first rubber pad 20 and the second rubber pad 22 serves to protect the nondestructive testing instrument 2, thereby reducing the impact of up and down vibration or shaking on the nondestructive testing instrument 2.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
