[0033] like Figures 1-6 As shown, the present invention discloses a steel pipe inner surface cleaning device, the main structure of which includes a steel pipe placement platform 1, a baffle 2, a steel pipe cleaning rod structure 3, a transverse moving structure 4, a rotating structure 5, a water injection structure 6, and a water tank 7. The device is mainly divided into two parts: the front part consists of the steel pipe placement platform 1, the baffle 2, and the water tank 7, and the rear part consists of the transverse moving structure 4, the rotating structure 5, and the water injection structure 6. The steel pipe cleaning rod structure 3 runs through both the front and rear parts.
[0034] The steel pipe placing table 1 is a stainless steel table body, and an arc-shaped groove 11 is arranged on the upper surface and extends from the front end of the steel pipe placing table 1 to the rear end of the steel pipe placing table 1. The arc-shaped groove 11 is used to position the steel pipe on the arc-shaped groove 11 and prevent the steel pipe from moving left and right. Generally, the steel pipe will not rotate when the steel pipe cleaning rod structure 3 cleans the inside of the steel pipe due to the weight of the steel pipe and the friction with the arc-shaped groove. If the steel pipe is relatively light, a fastening device can be added to the steel pipe to position the steel pipe in the arc-shaped groove 11. The length of the steel pipe to be cleaned is not longer than the length of the arc-shaped groove 11. The rear part of the steel pipe placing table 1 is provided with a baffle sliding groove 12. The baffle sliding groove 12 extends forward and backward, and the baffle 2 is slidingly installed in the baffle sliding groove 12. The baffle 2 can change the position on the steel pipe placing table 1 by sliding forward and backward. In order to cope with steel pipes of different lengths, it is necessary to adjust the position of the baffle 2. The baffle 2 with the adjusted position is fixedly connected to the baffle sliding groove 12 through a locking piece. In this way, the rear end of the steel pipe can be positioned at a predetermined position (in contact with the baffle 2) each time. In addition, the baffle 2 only blocks part of the steel pipe and does not completely block the opening of the steel pipe. Therefore, sewage can normally flow out from the rear end of the steel pipe and into the arc-shaped groove 11.
[0035] As shown in Figure 5 , the steel pipe cleaning rod structure 3 includes a cleaning rod 31 and a cleaning end 32. The cleaning end 32 is arranged at the front end of the cleaning rod 31 and has bristles on the surface. The length of the bristles is sufficient to contact the inner surface of the steel pipe. The bristles are hard and can scrape the inner surface of the steel pipe to effectively clean rust. The cleaning rod 31 is transversely arranged above the steel pipe placing table 1. The gap between the two is just enough for the steel pipe to pass through the cleaning rod 31 and then be placed in the arc-shaped groove 11. The rear end of the cleaning rod 31 extends to the rear of the baffle 2. The cleaning rod 31 is internally provided with a flushing water channel 33. The cleaning end 32 is provided with a flushing hole 34. The flushing hole 34 is in communication with the flushing water channel 33.

The sliding rails 45 are provided with meshing teeth. The transverse moving sliding seat 42 is slidingly installed on the bottom plate 41. The transverse moving motor 43 is fixed on the transverse moving sliding seat 42. The driving shaft of the transverse moving motor 43 is provided with the transverse moving meshing gear 44. The transverse moving meshing gear 44 is meshingly installed on the sliding rails 45. The transverse moving motor 43 can drive the transverse moving meshing gear 44 to rotate, thereby moving the transverse moving sliding seat 42 forward and backward on the bottom plate 41.
[0037] The rotating structure 5 comprises a rotating motor 51, an upper rotating gear 52, a lower rotating gear 53 and a belt 54, the rotating motor 51 is fixedly installed on the horizontal moving slide 42, the upper rotating gear 52 is coaxially fixed at the rear of the cleaning rod 31, the lower rotating gear 53 is fixedly connected with the motor shaft of the rotating motor 51, the belt 54 is wound on the upper rotating gear 52 and the lower rotating gear 53, the rotating motor 51 can drive the lower rotating gear 53 to rotate, and then the upper rotating gear 52 drives the cleaning rod 31 to rotate.
[0038] The water injection structure 6 comprises a water pump 61 and a sealing bearing 62, the water pump 61 is fixedly installed on the horizontal moving slide 42, one end of the water pump 61 is connected with the water tank 7 or an external water source, the other end of the water pump 61 is connected with the sealing bearing 62 through a water pump pipeline, the sealing bearing 62 is installed at the rear end of the cleaning rod 31, the sealing bearing 62 rotatably and sealingly connects the rear end of the cleaning rod 31 with the water pump pipeline, and the water pump pipeline is communicated with the flushing water flow channel 33.
[0039] Since the length of the cleaning rod 31 is relatively long, and the front half of the cleaning rod 31 is not provided with a supporting structure, two stable bearings for supporting the cleaning rod 31 are arranged at the rear of the cleaning rod 31, the two stable bearings are spaced apart by a certain distance, and the stability of the front end of the cleaning rod 31 is ensured.
[0040] When the utility model is used, the position of the baffle 2 is adjusted in advance, the baffle 2 is fixed, the steel pipe is sleeved on the cleaning rod 31, the rear end of the steel pipe abuts against the baffle 2, at this time, the cleaning end head 32 is located at the front end of the inner cavity of the steel pipe, the horizontal moving motor 43, the rotating motor 51 and the water pump 61 are started, the cleaning rod 31 rotates and moves backward at the same time, the flushing hole 34 sprays water to flush the inner surface of the steel pipe, the bristles can scrape the inner surface of the steel pipe, the water flows out from the front end and the rear end of the steel pipe to the arc-shaped groove 11, and then enters the water tank 7 through the sewage recovery hole 71, the cleaning rod 31 moves to the rear end of the steel pipe with the cleaning end head 32, the horizontal moving motor 43 is started in reverse, the cleaning rod 31 moves to the front end of the steel pipe with the cleaning end head 32, and the inner surface cleaning of the steel pipe is completed once.
[0041] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical scheme falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application are deemed to be within the protection scope of the present application.
