[0040] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0041] Example

[0042] like Figures 1 to 11 As shown, the present invention includes a detection platform 1, on which a water bath heating box 2 is provided, and the water bath heating box 2 is detachably connected to the detection platform 1; a heating rod 6 and a pressure gas generating device are provided on the water bath heating box 2, on which a disc 19 is provided, and on which a mounting hole is provided, the heating rod 6 is located in the mounting hole, and an annular groove is provided on the inner wall of the mounting hole, in which an expansion piece 12 is provided, and the expansion piece 12 and the annular groove form a closed cavity, the pressure gas generating device is connected to the closed cavity, and a grinding block 14 is provided on the expansion piece 12, and the expansion piece 12 is used to push the grinding block 14 to move radially along the heating rod 6; a vertical pipe 5 is also provided in the water bath heating box 2, and a conduit 10 is also provided on the disc 19, one end of the conduit 10 extends into the closed cavity, and the other end is detachably connected to the vertical pipe 5.

[0043] In view of the prior art, when the temperature sensor is heated in a water bath, the water bath heating box 2 is usually fixed on the detection platform 1, which makes it difficult to replace the water bath heating box 2. At the same time, the use of chemical agents to remove scale on the heating rod is likely to cause corrosion of the heating rod, affecting the heating efficiency of the heating rod. For this reason, the technical solution connects the water bath heating box 2 and the detection platform 1 in a detachable manner, which is convenient for replacing the water bath heating box 2 on the detection platform 1; at the same time, in order to facilitate the cleaning of the scale attached to the heating rod 6, a disc 19 is provided on the heating rod 6, and the disc 19 is mounted on the heating rod 6 through the mounting hole, so that the disc 19 can move on the heating rod 6; and in order to ensure that the disc 19 can move on the heating rod 6 during its movement. In order to clean the scale attached to the outer wall of the heating rod 6, an annular groove is arranged on the inner wall of the mounting hole of the disc 19, and the annular groove is distributed axially with the mounting hole and is connected end to end. An expansion piece 12 is arranged in the annular groove, and the expansion piece 12 is an airbag. A closed cavity is formed between the airbag and the annular groove. When the pressure gas generating device delivers pressurized gas into the closed cavity, the gas entering the closed cavity can force the expansion piece 12 to expand radially along the mounting hole, thereby pushing the grinding block 14 on the expansion piece 12 to fit the outer wall of the heating rod 6. In this way, when the disc 19 moves on the heating rod 6, the grinding block 14 attached to the outer wall of the heating rod 6 can effectively remove the scale attached to the heating rod 6, thereby achieving the purpose of removing the scale on the heating rod 6.

[0044] The pressure gas generating device provided in the present technical solution is an air pump. When the water bath heating box 2 is used to heat the temperature sensor, in order to make full use of the existing resources, a vertical pipe 5 is also provided in the water bath heating box 2. The vertical pipe 5 is detachably connected to the conduit 10 on the disc 19. In this way, when the water bath heating box 2 needs to stop working and the scale attached to the heating rod 6 needs to be removed, the conduit 10 and the vertical pipe 5 are in a disconnected state, and the gas transported to the disc 19 by the pressure gas generating device will cause the expansion piece 12 to expand, ensuring that the grinding block 14 can effectively fit on the outer wall of the heating rod 6; and when the water bath heating box 2 is working, the conduit 10 is connected to the vertical pipe 5. At this time, the gas transported to the disc 19 by the pressure medium generating device will be transferred to the vertical pipe 5 through the conduit 10, and finally flow out from the vertical pipe 5, thereby realizing the bubbling of the water in the water bath heating box 2, and then achieving the purpose of cleaning the temperature sensor placed in the water bath heating box 2.

[0045] This technical solution adopts the manufacturing method of the Industrial Internet of Things, which can not only remove the scale on the heating rod 6 in the heating box 2, but also perform bubble cleaning on the immersed sensor 9. The Industrial Internet of Things can support the realization of intelligent manufacturing and improve the automated scheduling and optimization of the production line.

[0046] A notch is provided on one side of the detection platform 1, and the water bath heating box 2 is located in the notch; a side baffle 3 and an L-shaped baffle 4 are also provided on the top of the detection platform 1, and the side baffle 3 and the L-shaped baffle 4 are both connected to the top of the detection platform 1 by bolts.

[0047] In order to achieve a detachable connection between the water bath heating box 2 and the detection platform 1 in this embodiment, a notch is provided on the detection platform 1 for placing the water bath heating box 2; at the same time, in order to ensure that the water bath heating box 2 can be stably located in the notch of the detection platform 1, a side baffle 3 and an L-shaped baffle 4 are also provided on the detection platform 1, wherein the side baffle 3 is used to limit one side of the water bath heating box 2 to prevent the water bath heating box 2 from moving left and right in the notch; the L-shaped baffle 4 is used to limit the front end of the water bath heating box 2 to prevent the water bath heating box 2 from moving out of the notch.

[0048] The heating rod 6 is of a U-shaped structure; a U-shaped groove 33 corresponding to the heating rod 6 is also provided on the inner wall of the water bath heating box 2, a slider 32 is provided in the U-shaped groove 33, and the slider 32 can slide in the U-shaped groove 33; a connecting block 31 is provided on the slider 32, and a hose 30 is provided on the connecting block 31, one end of the hose 30 extends into the disc 19 and communicates with the closed cavity, and the other end is connected to the pressure gas generating device.

[0049] In order to improve the heating efficiency of water in the present technical scheme, the heating rod 6 is set to a U-shaped structure. In order to ensure that the disc 19 mounted on the heating rod 6 can move on the heating rod 6, a U-shaped groove 33 is provided on the side wall of the water bath heating box 2 close to the heating rod 6. The projection of the U-shaped groove 33 in the horizontal direction is consistent with the projection of the heating rod 6 in the horizontal direction. Since the connecting block 31 and the disc 19 are connected by a hose 30 with a certain flexibility, when the slider 32 set in the U-shaped groove 33 moves, the disc 19 can be pulled to move together under the action of the hose 30, thereby realizing the movement of the disc 19 mounted on the heating rod 6 and achieving the purpose of removing scale attached to the outer wall of the heating rod 6.

[0050] A motor 34 is also provided on the top of the water bath heating box 2, and two pull ropes are also provided on the slider 32. The pull ropes are connected to the output shaft of the motor 34 after passing through the U-shaped slide groove 33, and the two pull ropes are wound around the output shaft of the motor 34 in opposite ways.

[0051] In order to achieve the purpose of automatically moving the slider set in the U-shaped chute 33 in this embodiment, thereby automatically removing the scale on the outer wall of the heating rod 6, a motor 34 is provided on the water bath heating box 2, and two pull ropes are wound around the output shaft of the motor 34. The two pull ropes are wound around the output shaft of the motor 34 in opposite directions, and the two pull ropes are connected to the slider 32 after passing through the two ends of the U-shaped chute 33. Therefore, when the motor 34 rotates forward, one of the pull ropes will gradually be wound around the output shaft of the motor 34, while the other pull rope originally wound around the output shaft of the motor 34 will be wound around the output shaft of the motor 34. The pull rope on the output shaft will be gradually untied, so that when the pull rope is gradually wound around the output shaft of the motor 34, it will pull the slider 32 to move in the U-shaped slot 33, thereby pulling the disc 19 sleeved on the heating rod 6 to move, thereby achieving the removal of scale on the heating rod 6; and when the motor 34 is reversed, another pull rope will be wound around the output shaft of the motor 34, thereby pulling the slider 32 to move in the U-shaped slot 33 in another direction, thereby achieving the reciprocating movement of the disc 19 on the heating rod 6, thereby better removing the scale on the heating rod 6.

[0052] A box body 7 is provided on the top of the vertical pipe 5, and the conduit 10 is communicated with the inside of the box body 7. A transverse tube 8 with an inner diameter the same as the outer diameter of the conduit 10 is provided on the inner wall of the box body 7. One end of the transverse tube 8 extends out of the box body 7, and the other end is a closed structure. The transverse tube 8 is located on the side wall of the box body 7 and is also provided with a first air hole 21; a connecting pipe 23 is provided in the closed end of the transverse tube 8, and a second air hole 22 and a third air hole 24 are also provided on the side wall of the connecting pipe 23, and the second air hole 22 and the third air hole 24 are respectively close to the two ends of the connecting pipe 23; the end of the conduit 10 away from the disk 19 is provided with a first connecting hole with an inner diameter the same as the outer diameter of the connecting pipe 23, a fixing plate 27 is provided in the conduit 10, and a first elastic member 26 is provided on the side wall of the fixing plate 27 facing the first connecting hole, and a blocking plate 25 for blocking the first connecting hole is provided on the first elastic member 26.

[0053] In this embodiment, in order to achieve communication between the conduit 10 and the vertical pipe 5, a box body 7 is provided on the top of the vertical pipe 5, and the top of the box body 7 is fixed to the inner bottom of the water bath heating box 2, so that the vertical pipe 5 can be suspended in the water bath heating box 2. In order to further improve the bubbling of water at different depths in the water bath heating box 2, a plurality of through holes are provided on the side wall of the vertical pipe 5.

[0054] When it is necessary to connect the vertical pipe 5 with the conduit 10, the conduit 10 on the disc 19 is moved to be flush with the transverse pipe 8, and then the conduit 10 is inserted into the transverse pipe 8. When the conduit 10 extends into the transverse pipe 8, the connecting pipe 23 arranged in the transverse pipe 8 is just inserted into the first connecting hole of the conduit 10, and the sealing plate 25 is pushed to compress the first elastic member 26, so that the third air hole 24 on the connecting pipe 23 is finally in the conduit 10. At this time, the conduit 10 and the transverse pipe 8 are in a connected state. Therefore, after the gas generated by the pressure gas generating device enters the conduit 10, the gas enters the connecting pipe 23 through the third air hole 24, and the gas entering the connecting pipe 23 enters the box body 7 through the second air hole 22 and the first air hole 21 in turn, so that the gas flows out from each through hole on the vertical pipe 5, so as to achieve the purpose of bubbling the water in the water bath heating box 2.

[0055] A second connecting hole 18 is also provided on the top of the disc 19, and a movable block 11 is also provided in the annular groove. The movable block 11 can move radially along the disc 19 in the annular groove; the conduit 10 passes through the movable block 11 and is connected to the closed cavity; a mounting groove is provided on the movable block 11, and a second elastic member 29 and a locking block 28 are provided in the mounting groove. The second elastic member 29 is used to push the locking block 28 to be inserted into the second connecting hole 18.

[0056] In this embodiment, in order to prevent the gas entering the closed cavity from the pressure gas generating device when clearing the scale on the heating rod 6, which may cause the connection between the conduit 10 and the cross tube 8, a second elastic member 29 and a locking block 28 are provided on the movable block 11. The elastic force generated by the second elastic member 29 is used to push the locking block 28 into the second connecting hole 18, so as to temporarily fix the movable block 11 in the annular groove. Therefore, when the pressure gas generating device transports gas into the closed cavity, since the conduit 10 is in a blocked state due to the action of the blocking plate 25, the gas entering the closed cavity will force the expansion member 12 to gradually expand.

[0057] A transverse plate 16 is also provided on the side wall of the box body 7, and the transverse plate 16 is sleeved on the heating rod 6. A limiting cylinder 13 is also provided at the bottom of the transverse plate 16, and the limiting cylinder 13 is sleeved on the heating rod 6; the outer diameter of the limiting cylinder 13 is smaller than the inner diameter of the mounting hole.

[0058] When it is necessary to connect the conduit 10 with the cross tube 8, in order to prevent the gas entering the closed cavity from causing the expansion piece 12 to expand, a limiting cylinder 13 is provided. When the disc 19 moves upward, the limiting cylinder 13 is inserted into the mounting hole of the disc 19, and the outer wall of the limiting cylinder 13 is used to block the grinding block 14, thereby limiting the movement of the grinding block 14 and preventing the expansion of the expansion piece 12.

[0059] A unlocking rod 15 is also provided at the bottom of the transverse plate, and the length of the unlocking rod 15 is consistent with the length of the second connecting hole 18 .

[0060] In order to realize automatic unlocking of the locking block 28, an unlocking rod 15 is provided. When the disc 19 moves upward on the heating rod 6, the unlocking rod 15 is inserted into the second connecting hole 18, pushing the locking block 28 to be removed from the second connecting hole 18, thereby realizing automatic unlocking of the locking block 28. At this time, when the pressure gas generating device delivers gas to the closed cavity, the gas enters the conduit 10. Since the conduit 10 is in a closed state at this time, as the pressure gas is continuously delivered to the closed cavity, the conduit 10 and the movable block 11 move in the annular groove, and finally the conduit 10 is extended into the cross tube 8, so that the cross tube 8 and the conduit 10 are connected.

[0061] A third elastic member 17 is also provided in the annular groove. The third elastic member 17 is sleeved on the conduit 10. When the conduit 10 moves toward the direction of the transverse tube 8, the movable block 11 will compress the third elastic member 17. Therefore, when it is necessary to disconnect the connection between the transverse tube 8 and the conduit 10, the pressure gas generating device is stopped from delivering gas into the closed cavity, and the movable block 11 can be pushed back under the action of the third elastic member 17.

[0062] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
