Description

The present invention relates to a pipe or duct probe for insertion into a pipe or duct, as described in claim 1. Furthermore, the present invention relates to a system comprising the pipe or duct probe according to the present invention. In sewer pipe technology, cleaning and coating devices are known that have tools mounted on flexible shafts, such as brushes or chain scrapers. The flexible shafts are driven here by external motors. These motors must be capable of applying large torques to cope with the resulting friction moments. When this type of flexible shaft rotates, it generates vibration, friction, and high torque, which essentially harms the application of the resin layer and makes the cleaning process more difficult. In addition, the aforementioned vibrations and friction, as well as high torque, increase wear on known cleaning and coating equipment. These are various figures relating to possible embodiments of a pipe or duct probe according to the present invention. Figures 1a to 1c are longitudinal cross-sectional views through a pipe or duct probe according to the present invention. This figure shows the system according to the present invention, along with a description of possible working methods. This is a diagram of the system according to the present invention, with a pipe or duct probe according to the present invention inserted into a pipe. In the following, the same reference numeral is used for similar parts that function similarly. Figures 1a to 1c and Figure 2 show the basic structure of possible embodiments of the pipe or duct probe 10. Figure 1a shows a side view of the pipe or duct probe. Figure 1b shows a front view of the pipe or duct probe. Figure 1c shows a perspective view of the pipe or duct probe 10 according to the present invention. Figure 2 shows a longitudinal cross-sectional view passing through the pipe or duct probe according to the present invention shown in Figures 1a to 1c. The pipe or duct probe 10 has a motor 15 (see Figure 2). The motor 15 itself has a motor housing, which is located within the housing 20. In other words, the motor 15 is mounted within the housing 20. Motor 15 is a DC motor. The design of the pipe or duct probe 10 according to the present invention eliminates the need to provide a separate AC motor. The motor 15 also has a motor shaft 18 (see Figure 2). The working means 30 is directly connected to the motor shaft 18. Furthermore, a connecting device 40 is shown. The connector 40 is used to connect the motor 15 to a cable (not shown here). A portion of the connector 40, particularly the cap-shaped portion 41, can form part of the capsule-shaped housing 20. The other end of the connector 40 is used to connect to the indicated cable using a mounting component 42. The centering device base 51 of the centering device 50 is formed on the housing 20 or partially surrounds the housing 20. The centering device base 51 is formed as an annular portion. Multiple elastic elements 55 are formed on the centering device base 51. As shown in Figure 1b, the elastic elements 55 are arranged at equal intervals from each other in the circumferential direction of the housing 20. The centering device base 51 can be interchangeably positioned on the housing 20. Various centering devices 50 can be mounted on the housing 20. Therefore, depending on the inner diameter of the pipe or duct, various centering devices 50 can be slid onto the housing 20 and connected to it. Eight resilient elements 55 (see Figure 1b) are formed in a manner similar to that of turbine blades. The elements 55 are preferably made of plastic material, thus allowing for a reduction or increase in the bending radius of the resilient elements 55. When the pipe or duct probe 10 is inserted into the pipe, the resilient elements 55 can bend in the direction of the central axis M, thus reducing the outer diameter of the centering device 50. The elastic element 55 does not have a constant width B in the longitudinal direction L. Rather, the elastic element 55 is formed in such a way that a certain type of convex surface is formed. On the one hand, this allows for proper centering of the pipe or duct probe 10 within the pipe, and on the other hand, it enables good flexibility. The housing 20 has a sealing cover or sealing cap 25. This sealing cap 25 is formed in the area of the motor shaft 18. A sealing material 35 is formed inside the sealing cap 25. The sealing material 35 prevents substances, particularly resin curing agent mixtures or other liquids, from entering the motor 15. In this case, the sealing material 35 is formed as a shaft ring seal. The shaft ring seal effectively prevents liquid from entering the housing 20, particularly the motor 15. The sealing cap 25 is preferably attached to the rest of the housing 20 in a manner that allows for the replacement or updating of the sealing material 35. For example, the sealing cap 25 is screwed onto another part of the housing 20. The working means 30
