[0032] Example 1

[0033] Reference Figure 1 - Figure 5 , which is the first embodiment of the present invention, provides a tubular cooler cleaning and detection device, which includes an installation component 100, including a receiving part 101, a component 102, an auxiliary component 103 and an amplification component 104, the component 102 is arranged on the receiving part 101, the auxiliary component 103 is arranged on the component 102, and the amplification component 104 is arranged on the auxiliary component 103.

[0034] Specifically, the accommodating member 101 includes a reflux sealing plate 101a, a tube sheet 101b and a conduction tube 101c. There are several conduction tubes 101c and the first and second rows are arranged alternately. The third row and the first row are arranged in the same number. The conduction tube 101c is installed between the two tube sheets 101b. The reflux sealing plate 101a is fixedly connected to one side of the tube sheet 101b. The reflux sealing plate 101a, the tube sheet 101b and the conduction tube 101c form a part of the tubular cooler for conduction.

[0035] Furthermore, component 102 includes a first mounting arc plate 102a movably connected to one side of the conductive tube 101c. The first mounting arc plate 102a is an arc structure in contact with the outer surface of the conductive tube 101c. The curvature of the first mounting arc plate 102a is between 70 degrees and 80 degrees. A connecting tube 102b is fixedly connected to one side of the first mounting arc plate 102a. There are two connecting tubes 102b, which are respectively arranged on both sides of the first mounting arc plate 102a. A second mounting arc plate 102c is fixedly connected to the other side of the connecting tube 102b. The structure of the second mounting arc plate 102c is the same as that of the first mounting arc plate 102a, and the angle on the conductive tube 101c is 180 degrees through the connection between the first mounting arc plate 102a, the connecting tube 102b and the second mounting arc plate 102c.

[0036] Furthermore, the auxiliary component 103 includes an upper movable groove 103a opened on the upper sides of the first mounting arc plate 102a and the second mounting arc plate 102c, the upper movable groove 103a and the first mounting arc plate 102a have the same curvature and a certain length, and a lower movable groove 103b opened on the lower sides of the first mounting arc plate 102a and the second mounting arc plate 102c, the opening of the lower movable groove 103b forms an "L"-shaped structural surface on the lower sides of the first mounting arc plate 102a and the second mounting arc plate 102c, and the notch of the lower movable groove 103b corresponds to the notch of the upper movable groove 103a.

[0037] Furthermore, the expansion component 104 includes a moving block 104a movably connected to the upper moving groove 103a, one side of the moving block 104a has a certain curvature to facilitate pushing the moving block 104a, and a moving plate 104b movably connected to the lower moving groove 103b, the upper side of the moving plate 104b is fixedly connected to the lower side of the moving block 104a, and the moving plate 104b is just in the lower moving groove 103b. As the moving block 104a moves in the upper moving groove 103a, the moving plate 104b moves in the lower moving groove 103b. When the moving block 104a moves to the other side of the upper moving groove 103a The connection between the first mounting arc plate 102a, the connecting tube 102b and the second mounting arc plate 102c enables an increase in the angle on the conducting tube 101c, thereby improving the installation stability of the component 102 and facilitating installation and disassembly. The first mounting arc plate 102a and the second mounting arc plate 102c have a clamping groove 103c on the other side of the lower moving groove 103b. The opening of the clamping groove 103c forms a relatively arranged "L"-shaped structure on the upper side surfaces of the first mounting arc plate 102a and the second mounting arc plate 102c, wherein the "one" part has the same length as the connecting tube 102b.

[0038] During operation, the patch sensor 203a is installed in the upper movable groove 103a on the first installation arc plate 102a and the second installation arc plate 102c. Since the upper movable groove 103a has a certain length and a shape with the same curvature as the first installation arc plate 102a, the detection member 203 can move along the groove, which is convenient for installation and adjustment. By pushing the moving block 104a, the moving block 104a moves along the upper movable groove 103a, thereby driving the moving plate 104b fixed on its lower side to move in the lower movable groove 103b. This design allows the detection member 203 to be flexibly adjusted along the length direction of the conductive tube 101c to meet the detection needs of different positions. The clamping grooves 103a opened on the first installation arc plate 102a and the second installation arc plate 102c c, so that during operation, the first mounting arc plate 102a and the second mounting arc plate 102c can form an "L"-shaped structure that is relatively set, and the "one" part of the clamping groove 103c is the same length as the connecting tube 102b, so that it can ensure that the fixing of the detection member 203 on the conductive tube 101c is more stable, and when the moving block 104a moves to the other side of the upper moving groove 103a, the angle on the conductive tube 101c is increased through the connection between the first mounting arc plate 102a, the connecting tube 102b and the second mounting arc plate 102c, thereby reducing the risk of equipment failure caused by improper installation, and due to the linkage design of the moving block 104a and the moving plate 104b, the installation and disassembly of the detection member 203 becomes more convenient and quick, thereby improving the maintenance efficiency.

[0039] Example 2

[0040] Reference Figure 1 - Figure 5 As the first embodiment of the present invention, a cleaning and detection device for a tubular cooler is provided. This device includes a fixing component 200, which includes a first compression member 201, a second compression member 202, a detection member 203, and an output member 204. The first compression member 201 is disposed on the component 102, the second compression member 202 is disposed on the component 102, the detection member 203 is disposed on the first compression member 201, and the output member 204 is disposed on the detection member 203.

[0041] Specifically, the first compression member 201 includes a first compression groove 201a opened on the first mounting arc plate 102a. The first compression groove 201a extends to the inner side of the first mounting arc plate 102a through the "|" part of the clamping groove 103c. A first elastic piece 201b is fixedly connected to the bottom side of the first compression groove 201a. One side of the first elastic piece 201b is forced to be squeezed into the first compression groove 201a, and the other side of the first elastic piece 201b is fixedly connected to a first clamping block 201c.

[0042] Furthermore, the second compression member 202 includes a second compression groove 202a opened on the second mounting arc plate 102c. The second compression groove 202a extends to the inner side of the second mounting arc plate 102c through the "|" part of the clamping groove 103c. A second elastic piece 202b is fixedly connected to the bottom side of the second compression groove 202a. One side of the second elastic piece 202b is forced to be squeezed into the second compression groove 202a, and the other side of the second elastic piece 202b is fixedly connected to a second clamping block 202c. The first clamping block 201c and the second clamping block 202c are oppositely arranged. In this way, the first clamping block 201c and the second clamping block 202c move into the first compression groove 201a and the second compression groove 202a respectively under the thrust, which is convenient for increasing the interval between the first clamping block 201c and the second clamping block 202c.

[0043] Still further, the detection member 203 includes a patch sensor 203a movably connected between the first clamping block 201c and the second clamping block 202c. A plug connector 203b fixedly connected to one side of the patch sensor 203a. The plug connector 203b is plugged and unplugged at one end of the connecting pipe 203c. The connecting pipe 203c is a hose with a certain length. The length of the connecting pipe 203c is convenient for covering the entire conduction pipe 101c. Connecting wires are arranged inside it to connect the patch sensor 203a. A plurality of adapters 203d are plugged and unplugged on the connecting pipe 203c. Each adapter 203d is fixedly connected to another patch sensor 203a. The length of the connecting pipe 203c and the patch sensors 203a on a plurality of adapters 203d are convenient for simultaneously detecting a plurality of conduction pipes 101c on the tubular cooler.

[0044] Furthermore, the output component 204 includes a transmission pipe 204a fixedly connected on one side of the connecting pipe 203c, the transmission pipe 204a is used to further connect several patch sensors 203a, and a signal acquisition board 204b fixedly connected on the other side of the transmission pipe 204a, the signal acquisition board 204b is used to collect the signal output by the patch sensor 203a.

[0045] During operation, by applying a thrust when installing the patch sensor 203a, the first clamping block 201c and the second clamping block 202c are moved into the first compression groove 201a and the second compression groove 202a respectively, increasing the distance between the two, thereby fixing the patch sensor 203a and ensuring good contact between the patch sensor 203a and the conductive tube 101c, wherein due to the length of the connecting pipe 203c, the conductive tube 101c at different positions can be selected for testing, and synchronous detection is performed with the assistance of the connecting pipe 203c, the plug connector 203b and the adapter 203d.

[0046] Example 3

[0047] Reference Figure 1 - Figure 6 , which is the third embodiment of the present invention, provides a tubular cooler cleaning detection device and method, the contents of which are as follows:

[0048] S1: first select a position to be detected, and then install the detection member 203 on the receiving member 101;

[0049] The position to be detected is the conduction tube 101c on the tubular cooler. One or several conduction tubes 101c can be selected for installation. The patch sensor 203a can be installed on the outer wall of the conduction tube 101c to detect the cleaning effect.

[0050] S2: then collect information through the output element 204 connected to the detection element 203;

[0051] The real-time temperature of the outer wall surface of the patch sensor 203a can be read through the signal acquisition board 204b.

[0052] S3: Finally, the collected information is read on the measurement and control host computer, and the boundary parameter conditions are input through the measurement and control host computer to read the real-time heat transfer coefficient data, and the cleanliness of the inner wall of the pipeline is converted through the heat exchange relationship to quantify the cleaning effect of the cooler;

[0053] The measurement and control host computer interface includes boundary parameter input in the heat exchange relationship, cleanliness evaluation, historical data wireframe, real-time parameters (temperature of the space outside the pipe, water flow in the pipe), measurement and control start button and other functional areas. The system integrates internal relationship for data calculation and measurement and control operation output.

[0054] The cleanliness of the transfer tube 101c is converted using a heat exchange relationship. This step involves the application of a mathematical model. For example, the following relationship can be used to describe it:

[0055]

[0056] Among them, η represents the efficiency of the cooler, P2 represents the heat absorbed by the cooler, P1 represents the total heat dissipated by the main transformer insulating oil, and n represents the number of cooler tube bundles;

[0057] The data obtained through the above steps can quantify the effectiveness of cooler cleaning. If the η value increases after cleaning, it means that the cleaning effect is significant and the heat exchange efficiency of the cooler is improved.

[0058] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, as well as parameter values, mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application.
