[0002] A vehicle-mounted drilling rig is a specialized oil exploration equipment used for oil drilling, mainly for operations such as lifting and lowering drill pipes, tubing, and sucker rods. When drilling in an oilfield, mud needs to be circulated to cool the drill bit and carry cuttings, etc. Since the mud has a certain viscosity, mud often accumulates on the drilling base table, making the drilling base table slippery, affecting the safe operation and personal safety of drilling operators, and even corroding and polluting the drill table surface, reducing the service life of the drilling base.

[0003] During the operation of the vehicle-mounted drilling rig, especially in a low-temperature environment, the collection and heating of mud are particularly important. Low temperature will cause the viscosity of the mud to increase and the fluidity to decrease, which not only affects the drilling efficiency of the drilling rig but may also cause damage to the drilling rig equipment.

[0004] Therefore, we propose a mud collection and heating device for the base of a low-temperature vehicle-mounted drilling rig. Content of the Utility Model

A temperature sensor is arranged at the position of the control box on the left side inner wall of the mud collection box. An alarm box is fixedly installed at the upper end of the control box on the left side wall surface of the mud collection box. A liquid level sensor is arranged at the top of the inner wall of the mud collection box.

[0013] Beneficial effects

[0014] The utility model provides a mud collection and heating device for a low-temperature vehicle-mounted drill rig base, which has the following beneficial effects:

[0015] 1. For the mud collection and heating device for a low-temperature vehicle-mounted drill rig base, by setting an electric heating element and a heat preservation composite layer, through the setting of the electric heating element, the heating function of the mud in the mud collection tank is realized, effectively solving the problems of increased mud viscosity and reduced fluidity in a low-temperature environment, improving the drilling efficiency of the drill rig, and protecting the drill rig equipment from damage. At the same time, the heating effect of the electric heating element can also reduce the accumulation and slipperiness of the mud, improve the safety of the drilling base table surface, and reduce the threat to the personal safety of the operators. Through the setting of the heat preservation composite layer, the heat preservation effect of the mud collection tank is further enhanced.
