Description

Technical Field

[0001] The utility model relates to the technical field of air flotation equipment, in particular to an air flotation pool scraping device. Background Art

[0002] According to the patent number CN117585755A, the name is: a flotation scraper device. By setting a telescopic plate, the length of the scraper can be adjusted when the water level inside the contact area rises due to rain. The rotating rod in the telescopic plate will drive the universal joint to rotate during the rotation process, and the universal joint will drive the screw at the other end to rotate. The height of the brush is adjusted to clean the scraper. In actual production, due to the complex structure, the failure rate is high. For this reason, we propose a flotation tank scraper device.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See attached Figure 1-5A flotation tank scraping device comprises a scraping frame 1 arranged on both sides of the edge of the flotation tank, a trapezoidal plate 2 arranged on the scraping frame 1, a rack 21 is laid on the upper part of the trapezoidal plate 2, and a scraper 3 connected between the scraping frames 1 by a chain 13. The side wall of the scraping frame 1 is provided with a first trough 11 for accommodating a sprocket 12 and a chain 13. The sprocket 12 is located on both sides of the inner side of the first trough 11. The chain 13 is sleeved on the sprocket 12 to form synchronous rotation. The sprocket 12 is also connected to a motor (not shown in the figure) for driving it to rotate. A gap is also reserved between the chain 13 and the inner side wall of the first trough 11 for fixing a fixing rod 35 on the scraper 3. A second trough 14 for accommodating a guide rod 34 on the scraper 3 is also provided on the scraping frame 1. The second trough 14 is arranged on the outer side of the first trough 11. The sizes of the second trough 14 and the guide rod 34 correspond. The guide rod 34 slides in the second trough 14 to guide the direction of the scraper 3.

[0025] In this embodiment, a groove 31 is longitudinally opened inward on the scraper 3, sliding grooves 32 are horizontally opened on both sides of the groove 31, and a lifting groove 33 is also opened on the inner wall of the sliding groove 32. A brush rod 4 is horizontally arranged in the groove 31, and both ends of the brush rod 4 extend to the outside of the scraper 3 and are connected to a brush rod gear 41 after passing through the sliding groove 32. The brush rod gear 41 is engaged with the rack 21 to drive the brush rod 4 to rotate in the groove 31. Since the brush rod gear 41 has to pass through the trapezoidal slope of the trapezoidal plate 2 before passing through the rack 21, the brush rod 4 will be lifted to the edge of the scraper, and then the rack 21 drives the brush rod 4 to rotate, thereby removing the dirt on the scraper surface.

[0026] Furthermore, in order to prevent the brush rod 4 from shaking in the sliding groove 32, a sleeve 42 is rotated on the brush rod 4, and a pair of symmetrically arranged extension rods 43 are connected to the cylindrical surface of the sleeve 42. The extension rods 43 extend into the lifting groove 33 to limit the sliding of the sleeve 42. A spring 44 is connected between the cylindrical surface of the sleeve 42 and the top inner wall of the sliding groove 32. After the brush rod 4 rises and rotates to clean the scraper, the spring 44 can reset the brush rod 4.

[0027] In this embodiment, a guide rod 34 and a fixed rod 35 are connected to the outer bottom of the scraper 3. The fixed rod 35 is fixed on the chain 13 of the scraping frame 1, and the guide rod 34 is embedded in the second groove body 14 to ensure the stability of the scraper 3 after rotation.

[0028] In this embodiment, an extension plate 22 is further connected between the scraping frame 1 and the trapezoidal plate 2 . The extension plate 22 compensates the height according to the length of the scraper 3 . The initial height of the brush rod gear 41 is consistent with the height of the trapezoidal plate 2 .

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
