[0049] In order to make the purpose, features and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0050] As shown in Figure 1 , it comprises a pool body 1, wherein the bottom wall of the pool body 1 is provided with two vertically upward extending partition plates 101, and the inner cavity of the pool body 1 is divided into a second chamber 103 and first chambers 102 located on both sides of the second chamber 103 by the two partition plates 101. Specifically, the second chamber 103 is located between the two partition plates 101, and the first chambers 102 are used to store solutions in order to oxidize aluminum profiles.

[0051] Among them, the first cleaning assembly 2 for cleaning the bottom wall of the first chamber 102 and the second cleaning assembly 3 for cleaning the side wall of the first chamber 102 are included, and the driving assembly 4 for driving the first cleaning assembly 2 and the second cleaning assembly 3 to move is also included.

[0052] As shown in Figure 1 andFigure 2 As shown, the bottom wall of the first chamber 102 is further provided with a sewage groove 1021, which is communicated with the side wall of the pool body 1 to form a sewage outlet 1022, wherein a detachable sealing cover 1023 is installed in the sewage outlet 1022.

[0053] In this embodiment, the first cleaning assembly 2 and the second cleaning assembly 3 can be driven by the driving assembly 4 to move towards or away from the sewage groove 1021, where the direction is redefined, the direction in which the first cleaning assembly 2 and the second cleaning assembly 3 move towards the side of the sewage groove 1021 is defined as the first direction X, and the direction in which the first cleaning assembly 2 and the second cleaning assembly 3 move away from the sewage groove 1021 is defined as the third direction Z, and the direction along the length of the sewage groove 1021 is defined as the second direction Y.

[0054] It is worth noting that the first direction X and the third direction Z are the width direction of the pool body 1, and the second direction Y is the length direction of the pool body 1.

[0055] In this embodiment, as shown in Figure 2 and Figure 3 The driving assembly 4 is installed in the second chamber 103 and located at the upper position of the pool body 1, and the driving assembly 4 includes a motor 41, a lead screw 42, a sliding block 43, and a frame 44, wherein the lead screw 42 is arranged along the width direction of the pool body 1, the motor 41 is fixedly installed on the pool body 1, the output shaft of the motor 41 is fixedly connected with the lead screw 42, the sliding block 43 is threadedly connected with the lead screw 42, and the side wall of the sliding block 43 abuts against the side wall of the second chamber 103, thereby preventing the sliding block 43 from rotating synchronously with the lead screw 42 during movement, wherein the frame 44 is fixedly connected with the sliding block 43 and installed in the first chamber 102, the first cleaning assembly 2 and the second cleaning assembly 3 are installed on the frame 44, thereby enabling the first cleaning assembly 2 and the second cleaning assembly 3 to be driven by the motor 41 to move along the first direction X or the third direction Z, achieving cleaning of the residues on the bottom wall and the side wall of the first chamber 102, and pushing the residues to the sewage groove 1021, thereby facilitating further processing of the accumulated residues.

[0056] It is worth noting that, as shown in Figure 1 The overflow port 1011 is located at the same horizontal plane as the lead screw 42, when the aluminum profile is placed in the first chamber 102 for oxidation, the solution in the first chamber 102 rises to the overflow port 1011, or flows to the second chamber 103 through the overflow port 1011, thereby preventing the solution in the first chamber 102 from flowing out of the pool body 1.

[0057] The sliding block 43 is provided with a connecting block extending through the overflow port 1011 to the first chamber 102, and the connecting block is used to fix the frame 44.

[0058] In order to improve the stability of the frame 44 when moving, in the embodiment, as shown in Figure 1 and Figure 3 shown, a guide mechanism 5 is further included to guide the frame 44, and specifically, the guide mechanism 5 includes a guide rod 51 fixedly installed on the pool body 1, wherein the frame 44 is in sliding connection with the guide rod 51, and it is worth noting that the guide rod 51 is arranged along the axial direction of the lead screw 42.

[0059] As shown in Figure 3 , the frame 44 adopts a rectangular structure, and the first cleaning assembly 2 is installed on the bottom frame of the frame 44 to clean the bottom wall of the first chamber 102, and the second cleaning assembly 3 is installed on the side frame of the frame 44 to clean the side wall of the first chamber 102.

[0060] Specifically, as shown in Figure 4 and Figure 6 , the first cleaning assembly 2 includes a guide plate 21 and a first scraper 23 rotatably installed on the guide plate 21, wherein the guide plate 21 is fixedly installed on the frame 44 by bolts, and when the first cleaning assembly 2 moves along the first direction X, the scraping end of the first scraper 23 abuts against the bottom wall of the first chamber 102 to push the residues on the bottom wall of the first chamber 102 to the drain groove 1021, and when the first cleaning assembly 2 moves along the third direction Z, as shown in Figure 5 , the scraping end of the first scraper 23 will be raised to avoid driving the residues to flow away from the drain groove 1021.

[0061] Specifically, as shown in Figure 4 and Figure 6 , the guide plate 21 is an arc-shaped plate, and after the residues on the bottom wall of the first chamber 102 are pushed by the first scraper 23, the residues move along the third direction Z relative to the first scraper 23, and then the residues flow to the guide plate 21, and under the flow guiding effect of the guide plate 21, the residues are reflowed to the front side of the first scraper 23, so that the residues can be smoothly pushed to the side of the drain groove 1021, preventing the residues from overflowing the first scraper 23 and causing incomplete cleaning of the residues.

[0062] Specifically, as shown in Figure 6 , the side of the guide plate 21 away from the drain groove 1021 is provided with a first positioning block 211, and the first scraper 23 is provided with a first limiting plate 231, wherein the first limiting plate 231 is in rotary connection with the first positioning block 211 through a first rotating shaft 232.

[0063] It is worth mentioning that when the first cleaning assembly 2 is installed on the frame 44, as shown in Figure 4 the scraping end of the first scraper 23 is arranged obliquely downward and forms an obtuse angle with the first direction, at this time, the first limiting plate 231 on the first scraper 23 abuts against the side wall of the guide plate 21 to limit the clockwise rotation of the first scraper 23 around the first rotating shaft 232.

[0064] When the driving assembly 4 drives the frame 44 to move along the first direction X, at this time, the first scraper 23 moves to the side of the drain groove 1021 to shovel the residues on the bottom wall of the first chamber 102, at this time, the residues will accumulate on the first scraper 23, under the action of the gravity of the first scraper 23, the scraping end of the first scraper 23 always abuts against the bottom wall of the first chamber 102, the residues are flipped onto the first scraper 23, the accumulation of the residues will exert a pressure on the first scraper 23 to make the first scraper 23 tend to rotate clockwise around the first rotating shaft 232, due to the abutment of the first limiting plate 231 and the guide plate 21, the included angle between the first scraper 23 and the first direction X can be maintained, and the residues will be re-flipped on the front side of the first scraper 23 through the guidance of the guide plate 21, so as to push the residues into the drain groove 1021.

[0065] When the driving assembly 4 drives the frame 44 to move along the third direction Z, at this time, the first scraper 23 gradually moves away from the drain groove 1021 to realize the retreat of the first scraper 23, and then, the first scraper 23 can be driven by the driving assembly 4 to move along the first direction X again to realize the repeated cleaning of the residues, in order to prevent the residues from being pushed to the side away from the drain groove 1021 during the retreat of the first scraper 23, as shown in Figure 5 when the first scraper 23 moves along the third direction Z, at this time, the residues will lift the first scraper 23 to make the first scraper 23 rotate counterclockwise around the first rotating shaft 232, so that the residues avoid the pushing of the first scraper 23, and with the multiple movements of the first scraper 23 along the first direction X, the residues on the bottom wall of the first chamber 102 can be completely cleaned.

[0066] As shown in Figure 4 the guide plate 21 is fixedly provided with a positioning plate 22 extending vertically upward, and the positioning plate 22 is fixedly connected with the frame 44 by screws.

[0067] Since the first scraper 23 is rotatably installed on the guide plate 21, a gap will exist at the connection between the first scraper 23 and the guide plate 21, and the residues will easily remain in the gap between the first scraper 23 and the guide plate 21 during the pushing of the residues, which will affect the cleaning effect of the residues, therefore, in the embodiment, as shown in Figure 4 and Figure 6As shown, the second cleaning assembly 3 further comprises a drainage strip 24 installed at the joint of the first scraper 23 and the guide plate 21, wherein the drainage strip 24 covers the gap between the first scraper 23 and the guide plate 21, the drainage strip 24 is fixedly installed on the guide plate 21, and the other side of the drainage strip 24 is overlapped on the first scraper 23, wherein the drainage strip 24 is elastic and can press the first scraper 23 downward so that the scraping end of the first scraper 23 is in contact with the bottom wall of the first chamber 102, when the frame 44 moves along the third direction Z, the residue will lift the first scraper 23 so that the drainage strip 24 is deformed, and after passing the residue, the first scraper 23 is reset, and the scraping end of the first scraper 23 is in contact with the bottom wall of the first chamber 102 again.

[0068] In order to clean the residue on the side wall of the first chamber 102, in the embodiment, as shown, Figure 7 the second cleaning assembly 3 comprises a second scraper 31, a second rotating shaft 32 and a torsional spring 33, wherein the side wall of the frame 44 is fixedly provided with a second positioning block 441, the second scraper 31 is rotatably installed on the second positioning block 441 through the second rotating shaft 32, the torsional spring 33 is sleeved on the second rotating shaft 32, one end of the torsional spring 33 is fixedly connected with the second scraper 31, and the other end of the torsional spring 33 is fixedly connected with the second positioning block 441, and specifically, the second scraper 31 is further provided with a second limiting plate 311, and the second limiting plate 311 is in abutment with the side wall of the frame 44, wherein the scraping end of the second scraper 31 is in abutment with the side wall of the first chamber 102.

[0069] Through the above arrangement, when the frame 44 moves along the first direction X, at this time, the scraping end of the second scraper 31 is in abutment with the side wall of the first chamber 102, and after the scraping end of the second scraper 31 contacts with the residue, the second scraper 31 has a tendency to rotate around the second rotating shaft 32, and the rotation of the second scraper 31 is limited due to the abutment of the second limiting plate 311 with the side wall of the frame 44, so that the residue on the side wall of the first chamber 102 can be pushed, and when the frame 44 moves along the third direction Z, at this time, the second scraper 31 retreats, and in the retreat process, the second scraper 31 contacts with the residue and is lifted up, so that the torsional spring 33 is twisted, and when the second scraper 31 passes the residue again, the second scraper 31 is reset under the torsional moment provided by the torsional spring 33, so that the scraping end of the second scraper 31 is always in abutment with the side wall of the first chamber 102.

[0070] When the first scraper 23 and the second scraper 31 push the residue into the inside of the drain groove 1021, at this time, the residue in the drain groove 1021 can be pushed out of the first chamber 102 through the drain opening 1022 by standing on the side of the pool body 1, so that the cleaning operation of the residue in the first chamber 102 is realized, and manual operation in the pool is not required, which is convenient for cleaning the residue.

[0071] In this embodiment, cleaning the residue on the side wall of the first chamber 102 refers to the residue on the partition plate 101 and the residue on the side wall opposite to the partition plate 101. The residue on the other two side walls of the first chamber 102 can be cleaned by standing at the edge of the pool body 1.

[0072] After the residue in the first chamber 102 is cleaned, the drain outlet 1022 can be sealed with the sealing cap 1023, so that the treatment liquid can be injected into the first chamber 102 to facilitate the oxidation of the aluminum profile.

[0073] like Figure 4 As shown, it is worth noting that the projection of the second cleaning component 3 on the bottom wall of the first chamber 102 is in front of the first cleaning component 2. Here, "in front" refers to the first direction X. The advantage of this arrangement is that after the second cleaning component 3 cleans the residue on the side wall of the first chamber 102, the residue will fall onto the bottom wall of the first chamber 102. As the frame 44 moves, the first cleaning component 2 will continue to push the fallen residue towards the drain trough 1021, thereby improving the cleaning efficiency of the residue.

[0074] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this disclosure can be achieved, and this is not limited herein.

[0075] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0076] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
