Description

Technical Field

[0001] This utility model relates to the field of electromagnetic emission technology, specifically an electromagnetic emission device for exploring physical field signals. Background Technology

[0002] Electromagnetic detection of the inner wall of a pipeline is based on electromagnetic emission. Specifically, electromagnetic detection technology emits electromagnetic signals of a specific frequency, which induce current in the inner wall of the pipeline, thereby forming a magnetic field. By detecting changes in these magnetic fields, the condition of the inner wall of the pipeline can be determined.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN218659105U) discloses an intelligent electromagnetic transmitting device for detecting physical field signals. The device includes a body and a support structure. A detector is fixedly connected to the surface of the body, and two wheels are rotatably connected to both sides of the body. The support structure, located on the upper surface of the body, includes a support frame. A threaded rod is threaded to the inner wall of the support frame, and a placement block is rotatably connected to the upper surface of the threaded rod. Rollers are rotatably connected to the surface of the placement block. A counterweight device, comprising two rectangular blocks and a storage box, is located on the surface of the rectangular blocks. The counterweight blocks are inserted into the inner wall of the storage box. The support frame, threaded rod, and rollers support the body, reducing the possibility of tipping over during movement. The roller positions can also be adjusted according to the size of the pipe.

[0004] When the aforementioned patent is in use, the contact between the rollers and the inner wall of the pipe reduces the possibility of the machine tipping over. However, the contact between the rollers and the inner wall of the pipe is adjusted by adjusting the threaded rod, so the roller contact is a rigid contact. When there are uneven objects, the rigid contact will affect the movement of the machine. At this time, the machine can only continue to move forward by tilting the support frame and the machine itself, which will still cause the machine to tip over and reduce the stability of the device's movement.

[0005] Therefore, this invention provides an electromagnetic transmitting device for exploring physical field signals to solve the above problems. Utility Model Content

[0010] A limiting component is provided above the machine body.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this application are as follows:

[0018] 1. This utility model uses the cooperation of rollers, hinge frame, support base and tension spring to make the rollers elastically abut against the inner wall of the pipe. When there are uneven surfaces on the inner wall of the pipe, the elastic change of the rollers can ensure the stable passage of the machine body, avoid hard abutment affecting the movement of the machine body, and effectively reduce the possibility of the machine body overturning.

[0019] 2. This utility model, through the cooperation of the sleeve, inner rod, and bolt fasteners, allows the installation height of the inner rod to be freely pulled up and down, thereby realizing the height adjustment of the support plate. This facilitates the contact protection of pipes of different diameters and ensures the stability of the machine's movement.

[0020] 3. This utility model, by setting a storage basket at the end of the machine body, can realize the counterweight placement treatment, thereby increasing the overall weight of the machine body. This not only improves the contact friction between the wheels and the pipes, but also reduces the occurrence of the machine body tilting up, further improving the stability of the machine body during driving.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-4As shown, this utility model provides an electromagnetic transmitting device for exploring physical field signals, including a body 1. A storage frame 12 is fixedly connected to the front end of the body 1. A protruding shell 13 is integrally provided on the top end of the body 1, and a first hinge rod 14 and a second hinge rod 15 are hinged to the outside of the protruding shell 13. The other ends of the first hinge rod 14 and the second hinge rod 15 are hinged to a positioning seat 16, and an electromagnetic detector 2 is fixedly connected to the front of the positioning seat 16. A limiting component 3 is disposed above the body 1. The limiting component 3 includes a vertically movable support plate 33, and a support base 34 is fixedly connected to the upper surface of the support plate 33. A hinge frame 35 is rotatably connected between the support bases 34. A roller 36 is rotatably connected to one end of the hinge frame 35. The other end of the hinge frame 35 is tensioned to the support plate 33 by a tension spring 37. The roller 36 is elastically supported and limited by the elastic contact between the roller 36 and the inner wall of the pipe, thereby avoiding the tilting of the machine body 1 caused by hard contact. At the same time, the roller 36 is located above the rear wheel 11, so that the downward pressure of the roller 36 can be transmitted to the machine body 1, further ensuring the overall stability of the machine body 1 during travel. The parallelogram linkage structure of the first hinge rod 14 and the second hinge rod 15 ensures that the positioning seat 16 maintains stable horizontal support.

[0029] Furthermore, wheels 11 are connected to the outside of the drive shaft of the machine body 1. The outer wall of the wheel 11 is provided with anti-slip texture. The storage frame 12 contains counterweights. By placing counterweights or other counterweights inside the storage frame 12, the overall weight of the machine body 1 can be increased, while reducing the possibility of the machine body 1 tilting, and further improving the stability of the machine body 1. At the same time, the increase in the overall weight of the machine body 1 further increases the contact friction between the wheels 11 and the inner wall of the pipe, ensuring its driving stability.

[0030] Furthermore, two sets of the first hinge rod 14 and the second hinge rod 15 are provided, and the two sets of the first hinge rod 14 and the second hinge rod 15 are symmetrically distributed on both sides of the protrusion housing 13. A support shaft 17 is fixedly connected between the two sets of second hinge rods 15. An electric push rod 18 is sleeved on the outside of the support shaft 17, and the other end of the electric push rod 18 is hinged to the upper surface of the protrusion housing 13. By controlling the electric push rod 18 with electricity, the support shaft 17 can be lifted and the displacement can be adjusted, thereby realizing the tilt adjustment of the second hinge rod 15, and thus adjusting the support height of the positioning seat 16, so that it can be adapted to pipes of different diameters for electromagnetic detection, ensuring that the electromagnetic detector 2 is in the center area of ​​the pipe.

[0031] Furthermore, the limiting component 3 includes a sleeve 31, which is fixedly connected to the upper surface of the body 1 by screws. An inner rod 32 is inserted into the inside of the sleeve 31, and a support plate 33 is fixedly connected to the top of the inner rod 32. There are two sets of limiting components 3, and the two sets of limiting components 3 are symmetrically distributed on both sides of the protrusion housing 13. Each set of limiting components 3 is provided with two sleeves 31 and inner rods 32. Multiple sets of adjustment holes are evenly distributed on the sleeves 31 and inner rods 32, and a bolt fastener passes through the inside of one set of adjustment holes. By adjusting the extension and retraction of the sleeves 31 and inner rods 32, the support height can be adjusted to adapt to different heights, thereby realizing the adjustment of the support plate 33 at different heights, so that the roller 36 can abut and limit pipes of different diameters.

[0032] Furthermore, the outer surface of the inner rod 32 is provided with scale lines, the end of the hinge frame 35 near the roller 36 is U-shaped, and the roller 36 is rotatably connected in the middle of the U-shaped structure. The end of the hinge frame 35 located on the roller 36 is higher than the other end. The scale lines facilitate the adjustment of its height. At the same time, the end of the hinge frame 35 that moves forward is lower, so that the roller 36 can pass through the concave and convex surfaces better.

[0033] Working principle: First, the contact height of the roller 36 is adjusted according to the diameter of the pipe. By moving the inner rod 32 upward, the roller 36 is elastically abutted against the inner wall of the pipe. Then, the machine body 1 is placed inside the pipe. The machine body 1 can be driven by power supply and its self-propelled detection is achieved by the wheels 11. At the same time, the electromagnetic detector 2 performs electromagnetic detection processing on the inner wall of the pipe.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
