DETAILED DESCRIPTION

[0018] The specific embodiments of the present application will be further described below with reference to the accompanying drawings. Identical parts are denoted by identical reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.

[0019] In order to make the content of the present application more easily understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Identical parts are denoted by identical reference numerals.​​

[0020] The embodiment provides an oilfield winter protection heat preservation detachable safety explosion-proof heat preservation sleeve, which comprises a cloth bag 1, wherein the cloth bag 1 is provided with an electric heat tracing heating device 2 and an electric heat tracing heating device fixing device 3.

[0021] In the embodiment, the electric heat tracing heating device 2 comprises an explosion-proof terminal box 201 and an explosion-proof junction box 202 fixedly arranged on the cloth bag 1. The explosion-proof terminal box 201 is used as a terminal sealing device of the explosion-proof electric heating belt, and the model of the explosion-proof terminal box is ZDFZH. The explosion-proof terminal box with the model has good electrical performance and protection level, and can ensure the stability and safety of power input. The model of the explosion-proof junction box 202 is ZDJH220V, which is used for connecting the explosion-proof electric heating belt 203 and a wire 204, and also has excellent electrical performance and protection level.

[0022] The explosion-proof electric heating belt 203 is arranged between the explosion-proof terminal box 201 and the explosion-proof junction box 202, and is used as a main heating element. The explosion-proof electric heating belt 203 can generate heat after being powered on, and can heat the oilfield equipment in the cloth bag 1. The material and specifications of the explosion-proof electric heating belt 203 are selected according to specific application requirements, so as to ensure the heating effect and safety.

[0023] The wire 204 is connected to the explosion-proof junction box 202, and an explosion-proof connector 205 is connected to one end of the wire 204 away from the explosion-proof junction box 202. The explosion-proof connector 205 can ensure electrical connection while preventing explosion accidents caused by electrical sparks or short circuits, thereby improving the safety of the explosion-proof heat preservation sleeve. The wire 206 is connected to one end of the explosion-proof connector 205 away from the wire 204, and the wire 206 is used for connecting with an external power supply or other electrical equipment.
