The invention discloses an air conditioner control method. The indoor environment temperature is detected through an indoor temperature sensor. The control method comprises the following steps that when an air conditioner runs, if it is judged that the indoor temperature sensor breaks down, the air conditioner is controlled to transmit indoor temperature sensor failure alarm information, and whether an indoor unit of the air conditioners is connected with a control terminal or not is judged; if the indoor unit is connected with the control terminal and only one control terminal is arranged, the current indoor environment temperature is obtained through the control terminal; and the air conditioner is controlled by taking the current indoor environment temperature obtained through the control terminal as a control parameter so that the air conditioner can run continuously. By means of the air conditioner control method, when the temperature sensor of the indoor unit breaks down, the air conditioner can obtain an indoor environment temperature substitute value while conducting failure alarm so that the indoor unit of the air conditioner can maintain subsequent running, and user experience is improved. The invention further discloses a computer readable storage medium, the air conditioner and a control device of the air conditioner.

The invention discloses a grinding wheel control device for a sander for a steel rail. The grinding wheel control device comprises a grinding wheel device and a rotation regulating mechanism. The grinding wheel control device is characterized in that the rotation regulating mechanism comprises a deflection regulating elbow; two ends of the deflection regulating elbow are horizontally arranged, and further, are each rotatablely mounted on two supporting shells; the middle part of the deflection regulating below is provided with a U-shaped bent part which is upwards concave; the middle part of the bent part is provided with a mounting block for mounting the grinding wheel device; one end of the deflection regulating elbow is a rotation regulating input end; the end part of the rotation regulating input end is provided with a worm wheel; the worm wheel cooperates with a worm vertically mounted on the supporting shell; the upper end of the worm upwards extends out of the supporting shell and is horizontally provided with a rotation control hand wheel. The grinding wheel control device can be used for the sander for the steel rail, so as to be better beneficial to the realization of the tightness regulation and the grinding direction regulation of a grinding wheel, and has advantages of being convenient to operate, flexible to regulate and convenient for realizing the continuous sanding of multiple side surfaces of the steel rail, and the like.

The invention discloses a servo device of a trenching machine pipe coiling system. The device comprises a speed reducer, a constant tension control mechanism and a driving mechanism, wherein the constant tension control mechanism is used for providing constant tension to a hydraulic rubber pipe in a trenching machine; the driving mechanism is used for transmitting the power output by the speed reducer to the constant tension control mechanism; the constant tension control mechanism comprises a plunger type hydraulic oil tank and an energy accumulator connected with the plunger type hydraulic oil tank through a first oil pipe; a second oil pipe is connected with the first oil pipe through a tee joint; the driving mechanism comprises a driving shaft, a gear driving mechanism and a screw rod driving mechanism; the driving shaft is connected with the speed reducer; the gear driving mechanism is connected with the driving shaft; and the screw rod driving mechanism is connected with the gear driving mechanism, used for converting the rotary movement of the gear driving mechanism into the linear movement of a plunger rod in the plunger type hydraulic oil tank and is connected with the plunger rod in the plunger type hydraulic oil tank. The servo device is compact in structure, reasonable in design, convenient to mount and use, complete in function, good in servo performance, good in constant tension control effect, stable and reliable in performance and high in popularization and application value.

The invention discloses a special take-out tool and a take-out method for a hydraulic injector. The special take-out tool for the hydraulic injector comprises a clamping take-out part and a handle part; the clamping take-out part consists of two parallel clamping bars; the middle parts of both the clamping bars are bent into a preset angle; the handle part consists of a vertical rod and a cross bar; the cross bar is fixed at one end of the vertical rod; and the other end of the vertical rod is fixedly connected to one end of the clamping take-out part. The invention ingeniously applies the lever principle, so that the force for pulling out the injector is greatly increased. When the special take-out tool for the hydraulic injector is in use, the handle part of the special take-out tool is grasped by an underwater robot; then a take-out part of the hydraulic injector is clamped by the tool; and by using the right angle point of the tool as the fulcrum, the handle part is repeatedly pressed by a manipulator of the underwater robot, so that the hydraulic injector can be rapidly taken out of an underwater facility injection hole and the success rate is ultrahigh.
