The utility model discloses an electric control cabinet mistaken touch prevention mechanism which comprises a cabinet body, a cabinet door is connected to the cabinet body through a hinge, a first handle is fixedly connected to one side of the cabinet door, a control assembly is arranged on the cabinet door, a partition plate is fixedly connected to the interior of the cabinet body, a plurality of first threaded holes are formed in the partition plate, and a plurality of second threaded holes are formed in the partition plate. A protection assembly is arranged on one side of the partition plate, a heat dissipation assembly is arranged on the cabinet body, and a plurality of maintenance openings are formed in the two sides of the cabinet body. According to the utility model, the protection assemblies are used for isolating the electric power components among the partition plates, so that the situation that when the electric power component in a certain partition plate is maintained, other electric power components are touched by mistake, so that the components are closed or an operator gets an electric shock is avoided, and potential dangers are avoided; and the deepest power components of the cabinet body can be directly maintained, and the front power components do not need to be disassembled, so that the maintenance process is simplified.

The invention provides an inorganic salt solid particle spheroidizing device. The inorganic salt solid particle spheroidizing device comprises a signal generation system, a vibration system, a stirring system and a dissolving system which are connected in sequence, the signal generation system is used for providing a vibration signal; the vibration system comprises a vibration exciter, a lower liquid storage tank, an upper liquid storage tank and a particle vibration plate arranged between the lower liquid storage tank and the upper liquid storage tank; the stirring system is arranged in the upper liquid storage tank; the dissolving system comprises a solvent inlet formed in the side face of the upper liquid storage tank and a solvent outlet formed in the bottom face of the lower liquid storage tank. The device is simple in structure, firm and durable, convenient to observe particle change and excellent in practicability; according to the invention, environmental protection can be realized, resources can be saved, and pollution-free continuous preparation of the spherical inorganic salt particles can be realized; the operation safety is high, the flexibility is high, and potential risks caused by liquid accumulation can be avoided through timely removal of the saturated solution.

The utility model discloses a new energy assembly aluminum profile angle code drilling equipment, including frame, positioning clamp and drilling assembly, the positioning clamp contains clamping station, the first support plate and second support plate (the included angle is identical with the angle code opening angle) of adjustable clamping angle, the first pressure cylinder (the angle code reinforcing rib of pressure tightness), the second / third pressure cylinder (the angle code of pressure tightness up and down), and the groove of avoiding drilling and pressing plate, drilling assembly is two groups, contains motor, transmission and electric drill head (the axis is perpendicular to the angle code side plate). The equipment still integrates feeding assembly (contains vibrator, angle -adjustable unloading baffle and limit plate) and unloading assembly (inclined unloading plate). Through adjustable clamping angle's support plate adaptation angle code common opening angle, multiple pressure tightness positioning ensures the machining accuracy, cooperates the automatic feeding / unloading, and significantly improves the processing efficiency and security, is applicable to the angle code batch drilling production of new energy equipment such as photovoltaic support, energy storage cabinet.

This invention discloses a cement sheath micro-gap pressure testing device, method, data, medium, and application, relating to the field of oil and gas well sealing technology. It includes an outer casing and an inner casing, with the outer casing fitted over the outer side of the inner casing, forming an annular cavity between them; a sealing element that seals the inner cavity of the inner casing; a pressure injection system connected to the inner cavity of the inner casing; a pressure control system connected to the pressure injection system; an acoustic logging tool housed within the inner cavity of the inner casing; a logging control system connected to the acoustic logging tool; a micro-gap size acquisition system; and a data association system. This invention can simulate the generation and evolution process of cement sheath micro-gap under varying downhole pressure conditions, establish a calibration relationship between acoustic response and micro-gap state, and provide experimental basis for evaluating cement sheath sealing integrity and optimizing cementing quality.

The application provides a vehicle control method and device, a vehicle, a chip and a storage medium, and relates to the field of vehicle control.The method comprises the following steps: in response to the fact that a vehicle receives a power-off command and identifies that an object in the vehicle leaves the vehicle, acquiring statistical characteristics of signal strengths of at least one broadcast signal monitored in a target period; wherein the target period is determined according to a first time and a time when the vehicle door is closed last time; the first time is a time when the driving speed of the vehicle reaches a speed threshold; determining whether there is a target device left in the vehicle cabin according to the statistical characteristics of the broadcast signals; and if there is, controlling the vehicle to give a reminder. Thus, the method does not require that an electronic device has a wireless charging function or that the electronic device establishes a connection with a vehicle Bluetooth module as a prerequisite, but only needs to acquire the statistical characteristics of the signal strengths of the broadcast signals monitored by the vehicle in the target period, so that it can effectively determine whether there is a left device in the vehicle, and the applicability of the method is improved.
