The invention provides a hot plug protection circuit and a circuit board, and relates to the technical field of circuit protection. In the hot plug protection circuit, the hot plug protection circuit is applied to a circuit board electrically connected with an external power supply, and an electromagnetic interference filtering module in the hot plug protection circuit is used for performing differential mode and common mode noise filtering on a first voltage output by the external power supply and outputting a second voltage; an electronic fusing module in the hot plug protection circuit comprises a voltage comparison unit and a voltage output unit which are electrically connected in sequence, and the voltage comparison unit is used for carrying out voltage comparison on a second voltage and a maximum voltage threshold value and a minimum voltage threshold value in a preset voltage threshold value range and outputting a voltage comparison signal. The voltage output unit is used for stopping supplying power to a post-stage circuit when the voltage comparison signal indicates that the second voltage is smaller than the minimum voltage threshold value, and outputting a target voltage when the voltage comparison signal indicates that the second voltage is larger than the maximum voltage threshold value; wherein the target voltage is the safe power supply voltage of the post-stage circuit.

The utility model relates to a forklift, in particular to an anti-toppling forklift. Comprising a forklift body and a fork arm carrier, a frame body is arranged at the bottom of the forklift body, electric sliding tables are symmetrically installed in the frame body, a weight bearing block sliding front and back in the frame body is arranged between sliding blocks of the two electric sliding tables, a cover plate is arranged on the frame body in a buckled mode, and an inclination angle sensor used for monitoring the inclination angle is arranged on the cover plate; an extension plate is arranged on the top of a fork frame of the fork arm carrier, and air cylinders are symmetrically installed in the extension plate. Through the structural arrangement that the air cylinders drive the side plates and the hinged plates, the stability of goods in the transportation process is ensured, forklift unbalance caused by goods sliding is prevented, the toppling risk is further reduced, meanwhile, the inclination angle of the forklift is monitored in real time by combining an inclination angle sensor and a weight bearing block driven by an electric sliding table, and the safety of the forklift is improved. And the position of the weight bearing block is adjusted according to needs, so that the gravity center of the forklift is dynamically adjusted, and the forklift is effectively prevented from toppling when the forklift carries heavy objects or runs on an unstable ground.

This utility model relates to the field of oil and gas extraction equipment technology, specifically to a mixed-transportation and pressurization device for negative pressure gas extraction. It includes a base frame and a mixed-transportation and pressurization main body. An integrated installation box is located on one side of the base frame, and several hydraulic bases are installed on the other side. The mixed-transportation and pressurization main body is housed within the integrated installation box and includes a mixed-transportation pump, a gas-liquid mixing pipeline, and a pressurization unit, used to pressurize the collected gas-liquid mixture and transport it to the gathering and transmission pipeline network. Compared to existing technologies, this application not only ensures the gas-liquid mixed-transportation and pressurization function during negative pressure gas extraction but also, through the inclusion of moving and opening / closing components, enables rapid deployment and position adjustment in complex field environments, thereby improving the equipment's adaptability and emergency response capabilities.
