The invention discloses a car covering device for a vehicle and a vehicle with the same. The car covering device comprises: a base, which is suitable for being installed on the outer top surface of the vehicle; a rotating shaft, which is rotatably arranged on the base; The driving device is connected to the rotating shaft; the car cover is connected to the rotating shaft; the upper shell is provided with a receiving cavity, and the base jointly defines a retractable opening, and the retractable opening is connected with the receiving cavity; the clutch device, the upper shell passes through the clutch device It is connected with the rotating shaft, wherein, the rotating shaft has a first rotating direction and a second rotating direction opposite to the first rotating direction, when the rotating shaft rotates along the second rotating direction, the clutch device makes the rotating shaft and the upper casing rotate relatively so as to pass the clothing through the collection The opening is retracted into the accommodation cavity, and when the rotation shaft rotates along the first rotation direction, the clutch device makes the upper casing rotate together with the rotation shaft so as to throw the car clothing out of the accommodation cavity through the storage opening. The car covering device for vehicles according to the embodiment of the present invention has the advantages of convenient use, good retractable effect, and the like.

The invention relates to an intelligent logging instrument for coal bed gas prospecting based on Internet of Things. The intelligent logging instrument comprises a main engine, a winch frame, a winch,a transmission line, a detecting stick, a steady mechanism and a guide line mechanism. According to the intelligent logging instrument for coal bed gas prospecting based on the Internet of Things, when the detecting stick stretches into the downhole to perform a logging work, through starting the steady mechanism, the detecting stick keeps steady as moving down, the detecting stick is prevented from sloshing during in the process of moving down, not only can the damage caused by the collision of the detecting stick to the rock wall be avoided, but also avoid the impact on the detecting stick;and secondly, when the winch is pulling in and out of the transmission line, the transmission line is always kept perpendicular to the axis of the winch by starting the guide line mechanism, so thatjamming of the transmission line can be avoided, thereby improving the effect of the collection, and the normal use of the logging instrument is avoided to be influenced.

The invention relates to the field of sewage treatment equipment, in particular to an operation control method of an oil pollution transfer vehicle. The operation control method respectively controls the four working processes of oil suction and oil removal; sewage suction and sewage discharge; among them, the control method of the sewage suction process is as follows: S1: initialization setting; S2: related to sewage suction The pipeline is switched to the conduction state; S3: release the hose; S4: pull the hose to the ship; S5, end the pipe release and connect the pipeline; S6: turn on the pump mechanism; S7: recoil the hose; the sewage The operation steps of the discharge process are as follows: S01: Initialize the equipment; S02: Mix and stir the sewage; S03: Turn on the pump body for sewage discharge; S04: Monitor the liquid level of the sewage storage tank; S05: Restore the initial state; The degree of automation of oil pollution transfer vehicles has been greatly improved, which can significantly improve the efficiency of oil pollution transfer vehicles and reduce the workload of operators.

The invention relates to an intelligent flame cutting machine. The intelligent flame cutting machine comprises a base, a cutting table, a cutting bridge and a cutting head; the base is provided with a pressing mechanism and a wire collecting mechanism; the pressing mechanism includes a cylinder, a driving plate, a support column, a fixed ring and a pressing module; the pressing module includes two pressing units; the pressing units include first support rods, second support rods, third support rods, pressing plates and connecting ropes; and the wire collecting mechanism includes a first motor, a wire collecting shaft, a second motor, a lead screw, a slide rod and a slide block. In the intelligent flame cutting machine, after raw materials are placed on the cutting table, the raw materials are fixed on the cutting table through the pressing mechanism; the pressing mechanism can increase the pressing area, so that the stability of the raw materials is improved, the cutting precision is improved, and the reject rate is reduced; in addition, gas transmission pipes are stored and freely collected and placed as needed through the wire collecting mechanism, so that the gas transmission pipes are not liable to wind; and the wire collecting mechanism can prevent blockage of the gas transmission pipes to improve the collecting and placing effects.

The invention discloses a tension control method, device and system of rolling and unrolling equipment. The tension control method comprises the steps of obtaining the current linear velocity V<n> of operation of a material and the current frequency f<n> of a motor rotor; calculating out the current rolling diameter calculated value D<n> of the outer diameter of the material on a roller wheel every other time cycle T according to the obtained current linear velocity V<n> and the current frequency f<n> of the motor rotor; comparing the current rolling diameter calculated value D<n> with a predetermined limiting condition, and determining the current rolling diameter determined value; according to the current rolling diameter determined value, controlling a motor to output a corresponding force moment. According to the tension control method, device and system of the rolling and unrolling equipment, due to the fact that a tension controller calculates out the current rolling diameter calculated value by obtaining the material operation linear velocity, then conducts error judgment on the current rolling diameter calculated value obtained through calculation, conducts judgment by comparing the current rolling diameter calculated value with the limiting condition and finally controls a frequency converter to output the corresponding force moment according to the current rolling diameter determined value obtained through calculation and judgment, the material on the roller wheel can obtain constant tensile force all the time, the material can be rolled and unrolled more stably, and the rolling and unrolling effect is better.
