This invention discloses a method, system, and device for detecting weak seismic signals based on instantaneous phase analysis, relating to the field of reservoir prediction. The method includes: 1. Inputting a three-dimensional seismic data volume; 2. Extracting the amplitude data of the current seismic trace and recording it as a one-dimensional array; 3. Performing a -90° phase shift on the one-dimensional array to obtain a phase shift array; 4. Performing a time-frequency continuous wavelet transform on the phase shift array to obtain multiple common-frequency amplitude arrays; 5. Performing a Hilbert transform on each common-frequency amplitude array to obtain the corresponding instantaneous phase array; 6. Calculating the second derivative of each instantaneous phase array with respect to the time variable n to obtain a three-dimensional data volume indicating weak signals at the current seismic trace's common frequency; 7. Changing the seismic trace and repeating steps 2-6 to obtain multiple three-dimensional data volumes indicating weak signals at the common frequency; 8. Selecting the optimal weak signal indicator data volume. This invention can effectively find the three-dimensional data volume indicating weak signals, improving the accuracy of detection.

The electric kettle comprises a base, a kettle body arranged on the base, a heating device and a temperature control device, and is characterized in that the temperature control device comprises a power supply main controller and a sliding temperature adjusting assembly, and the sliding temperature adjusting assembly comprises a touch control module, a first display and a touch sliding temperature adjusting area which are in circuit connection with the power supply main controller; when a finger touches and slides in the touch sliding temperature adjusting area, the water temperature in the kettle body is set through the matching effect of the touch control module and the power source main controller, and the first displayer is at least used for displaying the set temperature under the control of the power source main controller. The temperature control device is provided with a brand-new human-computer interaction interface, temperature adjustment can be achieved by sliding a finger on the temperature control device, and the temperature control device can rapidly and accurately rise and fall to a certain temperature value. The continuous sliding temperature regulation mode is novel and smooth in operation mode, more accurate in temperature regulation and control, attractive in overall appearance, high in grade, simple and reliable in structure and low in production cost.

The utility model belongs to the technical field of traffic indication equipment, and particularly relates to a traffic sign post which comprises an indication board. The device comprises a rod body, a horizontal guide rail, a vertical guide rail, a horizontal locking piece, a vertical connecting piece and a vertical locking piece, a cross rod perpendicular to the rod body is arranged at the top of the rod body; the horizontal guide rail is arranged on the indication board, the horizontal guide rail and the cross rod are distributed in parallel, and a sliding block is arranged on the horizontal guide rail in the axial direction of the cross rod in a sliding mode; the vertical guide rail is arranged on the sliding block; the horizontal locking piece can lock the sliding block at the current position on the horizontal guide rail and can unlock the sliding block; the vertical guide rail can be connected to the transverse rod through the vertical connecting piece, and the vertical connecting piece can vertically move on the vertical guide rail. The vertical locking piece can lock the vertical connecting piece at the current position on the vertical guide rail and can unlock the vertical connecting piece; compared with the prior art, after the traffic sign post is installed and fixed, the height and the horizontal position of the sign can be adjusted, the application range is wide, and an operator can adjust and operate the traffic sign post easily.

This utility model discloses a surge arrester disconnector, including a disconnector housing, a high-voltage electrode disposed inside the disconnector housing, and a grounding electrode installed at the bottom of the disconnector housing. An electronic resistor is disposed inside the disconnector housing, and a second spring is sleeved on the outside of the electronic resistor. A thermal nail gun is installed at the bottom of the electronic resistor. An indicator shell is slidably mounted on the outside of the disconnector housing. Connecting rods are symmetrically arranged on the outside of the high-voltage electrode. Low-temperature solder is provided between the two connecting rods and the indicator shell. Multiple vertical rods are integrally formed on the inner side of the indicator shell, and a first spring is sleeved on the outside of the vertical rods. This utility model, through the use of low-temperature solder, the first spring, the vertical rods, and the connecting rods, ensures that when the surge arrester malfunctions or ages, the indicator shell will automatically separate from the disconnector housing, thus exposing the red outer shell of the disconnector housing for indication, resulting in a very clear indication effect.
