[0024] The embodiment of the present application discloses an anti-collision type pipeline electric heater.

[0025] Reference Figure 1-2 The anti-collision type pipe electric heater includes a heater body 1 and an anti-collision component 2. The heater body 1 includes a heat-conducting inner tube 11 for liquid to flow through. The two ends of the heat-conducting inner tube 11 are connected to the pipes at both ends through flanges. A heating element is installed on the peripheral side wall of the heat-conducting inner tube 11 through a metal mounting seat. The heating element is energized and the temperature is adjusted by a thermostat. An insulating outer tube 12 is arranged on the outside of the mounting seat.

In this embodiment, two groups of anti-collision components 2 are arranged, and the two groups of anti-collision components 2 are respectively arranged near the two ends of the heater body 1. The anti-collision component 2 includes a support base 21 and an anti-collision ring 22. The support base 21 is arranged below the heater body 1 and outside the insulation outer tube 12. The support base 21 is gradually expanded from top to bottom, and the bottom length of the support base 21 is greater than the overall diameter of the anti-collision ring 22, thereby improving the stability of the support base 21.

[0027] The anti-collision ring 22 includes two semi-annular unit ring bodies 221, which are rotatably connected to the two ends of the support base 21 respectively. The two unit ring bodies 221 are located on both sides of the radial direction of the outer tube. The top surface of the support base 21 and the inner surface of the unit ring body 221 are both curved surfaces and are adapted to the curvature of the outer peripheral surface of the insulation outer tube 12.

[0028] An anti-collision pad 3 is provided on the inner wall of the unit ring body 221, and the anti-collision pad 3 is interference-fitted with the outer peripheral wall of the heat-insulating outer tube 12. A shock-absorbing pad 4 is provided on the top surface of the support base 21, and the shock-absorbing pad 4 is interference-fitted with the outer peripheral wall of the heat-insulating outer tube 12. The anti-collision pad 3 and the shock-absorbing pad 4 are both made of rubber material.

[0029] When the heater body 1 is hit, the anti-collision pad 3 and the shock-absorbing pad 4 provide a protective function of buffering and shock-absorbing the heater body 1, thereby reducing damage to the pipeline electric heater and ensuring the service life of the pipeline electric heater.

[0030] The inner wall of the unit ring body 221 is provided with a receiving groove 5 for embedding the crash pad 3. The crash pad 3 is clamped in the receiving groove 5 and has an interference fit with the receiving groove 5. The thickness of the crash pad 3 is greater than the depth of the receiving groove 5. The peripheral side wall of the crash pad 3 is integrally formed with a mounting ring edge 31. The inner peripheral wall of the receiving groove 5 is provided with a mounting ring groove 51 for clamping the mounting ring edge 31. The mounting ring edge 31 has an interference fit with the mounting ring groove 51. When assembling the crash pad 3, just clamp the mounting ring edge 31 into the mounting ring groove 51, which is convenient to operate.

[0031] The inner wall of the support base 21 is provided with a placement groove 6 for the shock-absorbing pad 4 to be embedded. The shock-absorbing pad 4 is clamped in the placement groove 6 and has an interference fit with the placement groove 6. The thickness of the shock-absorbing pad 4 is greater than the depth of the placement groove 6.

The nuts of the connecting bolts 72 and the connecting nuts 73 are respectively in contact with the sides of the connecting plates 71 away from each other.

[0033] When assembling the pipe electric heater, the two unit ring bodies 221 are rotated in the direction away from each other until they are open, and then the heater body 1 is placed on the curved surface of the support base 21 so that the shock-absorbing pad 4 is squeezed, and then the two unit ring bodies 221 are rotated in the direction close to each other until the connecting plates 71 are close to each other, so that the anti-collision pad 3 is squeezed, and finally the connecting bolts 72 are passed through the two connecting plates 71 in turn and the connecting nuts 73 are threadedly connected to the connecting bolts 72, so that the nuts of the connecting bolts 72 and the connecting nuts 73 are respectively abutted against the sides of the connecting plates 71 away from each other, and the assembly is completed.
