DETAILED DESCRIPTION

[0016] 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.

[0017] like Figures 1 to 3 As shown, a condenser cooling tube replacement device comprises a first cooling tube 2 and a second cooling tube 3, wherein a first connecting tube 21 is fixed on the first cooling tube 2, and a second connecting tube 31 is fixed on the second cooling tube 3, the first connecting tube 21 of the first cooling tube 2 and the second connecting tube 31 of the second cooling tube 3 are spliced ​​and connected by a first bolt 8; a third detection tube 32 is also sleeved on the second cooling tube 3, and the third detection tube 32 is fixedly connected to the second connecting tube 31, and a first detection box 41 and a second detection box 42 are fixed on both sides of the third detection tube 32, a laser sensor emitting end 411 is installed in the first detection box 41, and a laser sensor receiving end 421 is installed in the second detection box 42, and the third detection tube 32 is symmetrically connected with a first through hole 321, and a transparent window 5 is installed on the first cooling tube 2, and the laser sensor emitting end 411 passes through the transparent window 5 on the first cooling tube 2 and is aligned with another transparent window 5 on the first cooling tube 2 and the laser sensor receiving end 421. A plurality of cleaning rubber balls 7 are arranged inside the tube wall of the first cooling tube 2 and the tube wall of the second cooling tube 3 .

[0018] In the present invention, the laser sensor transmitting end 411 and the laser sensor receiving end 421 are prior art.

[0019] With the above structure, the first cooling tube 2 is spliced ​​with the second connecting tube 31 of the second cooling tube 3 through the first connecting tube 21, and the first cooling tube 2 and the second cooling tube 3 are fixed by the first bolt 8, which is conducive to the quick disassembly and assembly of the first cooling tube 2 and the second cooling tube 3, and the installation is more convenient; at the same time, a laser sensor transmitting end 411 and a laser sensor receiving end 421 are arranged on both sides of the third detection tube 32, and the laser sensor transmitting end 411 and the laser sensor receiving end 421 are coaxially installed, and the axes of the laser sensor transmitting end 411 and the laser sensor receiving end 421 intersect the axis of the first cooling tube 2 at right angles. The laser sensor transmitting end 411 emits the laser, which passes through the transparent window 5 on one side of the first cooling tube 2, the inside of the first cooling tube 2, and the transparent window 5 on the other side of the first cooling tube 2 in sequence, and is finally received by the laser sensor receiving end 421. When the cleaning rubber ball 7 passes through the inner wall of the first cooling tube 2, it will block the path of the laser emission from the laser sensor transmitting end 411 to the laser sensor receiving end 421, and the laser sensor receiving end 421 will automatically count it once. By setting the laser sensor transmitting end 411 and the laser sensor receiving end 421, it is beneficial to accurately count the cleaning balls, and the counting work efficiency is higher.

[0020] Specifically, if Figures 1 to 3 As shown, a first annular groove 211 is provided on the first connecting tube 21, and a first annular limiting portion 311 is provided on the second connecting tube 31. The first annular limiting portion 311 is clamped and limited with the first annular groove 211. With this structure, the first annular limiting portion 311 is clamped in the first annular groove 211, which is beneficial for the first connecting tube 21 of the first cooling tube 2 and the second connecting tube 31 of the second cooling tube 3 to be connected and fixed more securely, with a stable structure, and at the same time, it is convenient to splice the first cooling tube 2 and the second cooling tube 3.

[0021] like Figures 1 to 3 As shown, the first connecting tube 21 also has a second annular limiting portion 212, and the second connecting tube 31 has a third annular limiting portion 312. A second annular groove 313 is provided between the third annular limiting portion 312 and the first annular limiting portion 311, and the second annular limiting portion 212 is engaged with the second annular groove 313 for limiting.

[0022] With the above structure, the second annular limiting portion 212 is engaged with the second annular groove 313, which is conducive to more reliable connection and fixation of the first connecting tube 21 of the first cooling tube 2 and the second connecting tube 31 of the second cooling tube 3, and a more stable structure.

[0024] With the above structure, the first bolt 8 passes through the second threaded hole 6 of the first annular limiting portion 311 and the second annular limiting portion 212 and is threadedly connected in the second threaded hole 6, which is conducive to facilitating the splicing of the first cooling pipe 2 and the second cooling pipe 3 and fixing them to each other, and the structure is firm and stable.

[0025] like Figures 1 to 3 As shown, the glass material of the transparent window 5 is high temperature resistant glass.

[0026] In the present invention, the transparent window 5 is a prior art, which is a common window made of high temperature resistant glass.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention.
