In some implementations, the first measuring assembly 2 may include two first sliding sleeves 201, and the first sliding sleeves 201 are spaced apart from each other and fit on the main ruler 1. Thus, when measuring the corrugation pitch of the corrugation of the plate heat exchanger, the measurement can be carried out only by adjusting the distance between the two first sliding sleeves 201.

Of course, the above-mentioned embodiment in which the first measuring assembly 2 includes two first sliding sleeves 201 is illustrative, and in other embodiments, other structures may be adopted. For example, the first measuring assembly 2 may comprise a first sliding sleeve 201 and set a starting point and a scale on the main scale 1, such that the corrugation pitch of the plate heat exchanger corrugations is measured according to the distance between the first sliding sleeve 201 and the starting point on the main scale 1 by sliding the first sliding sleeve 201 along the main scale 1.

In this way, the fixed base 202 can be fixed on the upper end of one of the first sliding sleeves 201, one end of the straight ruler 203 is fixed in the fixed base 202, then the ruler sleeve 204 is fixed on the upper end of the other first sliding sleeve 201, and the ruler sleeve 204 can slide along the first sliding sleeve 201 to drive the ruler sleeve 204 to slide synchronously along the straight ruler 203, so that the ripple pitch can be determined through the distance between the fixed base 202 and the ruler sleeve 204, namely, through the reading between the two on the straight ruler 203.

It should be noted that locking members are also provided on the two first sliding sleeves 201, and the locking members are used for locking the first sliding sleeves 201 on the main scale 1.

In some practical manners, the second measuring assembly 3 may include a housing 301, a top portion of the housing 301 is fixedly connected to the first measuring assembly 2, a vertical ruler 302 slidably connected to the housing 301 is disposed in the housing 301, a roller 303 is disposed at an outer end of the vertical ruler 302, and a positioning member 304 is disposed on the housing 301, wherein the positioning member 304 is used for fixing the vertical ruler 302 at a set position of the housing 301. Therefore, the main ruler 1 is attached to the highest point of the corrugation of the plate heat exchanger, then the vertical ruler 302 extends downwards, the roller 303 is attached to the lowest point of the corrugation of the plate heat exchanger, then the vertical ruler 302 is fixed through the positioning piece 304, and the depth of the corrugation is determined according to the distance of the downward extension of the vertical ruler 302.

Specifically, the positioning member 304 may be a locking screw, and after the vertical ruler 302 is moved to a designated position, the vertical ruler 302 and the housing 301 may be fixed by the locking screw.

Thus, on the basis of the two first sliding sleeves 201, one of the first sliding sleeves 201 is moved to a corrugated peak position, the second sliding sleeve 305 at the vertical ruler 302 corresponding to the first sliding sleeve 201 extends downwards to drive the positioning plate 306 to be attached to the peak position, then the other first sliding sleeve 201 is adjusted to slide to a corresponding corrugated trough position along the main ruler 1, the vertical ruler corresponding to the first sliding sleeve 201 extends downwards, the roller 303 is attached to the corrugated trough position, and the corrugated depth is determined according to the distance of the downward extension of the vertical ruler 302.

In some implementations, the third measuring assembly 4 may include a connection plate 5, a measuring wheel 6 is rotatably disposed in the connection plate 5, and a counter 7 is disposed on the measuring wheel 6, wherein the counter 7 is used for recording the number of rolling turns of the measuring wheel 6. In this way, the surface pitch of the corrugations of the plate heat exchanger is measured by the measuring wheel 6 rolling from the crest position of the corrugations along the surface of the corrugations until it rolls to the trough position of the corrugations, at which time the distance over which the measuring wheel 6 rolls is read by the counter 7.

It should be noted that the peak positions and the valley positions of the plate heat exchanger can be measured by combining the first measuring unit 2 and the second measuring unit 3, and then the peak positions and the valley positions are marked by a marker pen or other identification sticker, so that the counter 7 of the measuring wheel 6 is aligned with the peak positions to start rolling along the surface of the corrugation until the counter rolls to the valley positions, thereby completing the measurement. In addition, the counter 7 is an existing device, and a detailed structure thereof is not described herein.

Of course, when the rolling distance of the measuring wheel 6 is less than one turn, the scale 8 can be read by the peripheral side wall of the measuring wheel 6.
