6results about How to "Realize the integration function" patented technology

The invention discloses a vibration self-sensing device based on a piezoelectric effect and a working method, relates to the technical field of vibration isolation, and solves the problems that a traditional control system is low in integration level, large in size and weight, serious in sensing and driving signal coupling interference and difficult to realize high-frequency response closed-loop control. The lower end of a piezoelectric actuator is connected with a connecting copper block, and a piezoelectric sensor is arranged in a groove in the bottom of the connecting copper block; the piezoelectric actuator comprises an actuator rotor, an actuator shell and a piezoelectric plate pile, the actuator shell is of a cylindrical structure, the actuator rotor and the piezoelectric plate pile are arranged in the actuator shell, and the piezoelectric plate pile is arranged below the actuator rotor and drives the actuator rotor to move up and down; and the piezoelectric patch stack is in signal connection with the piezoelectric sensor. According to the invention, the piezoelectric sensor and the piezoelectric actuator are deeply fused, so that a single piezoelectric element has dual functions of execution and sensing. When the actuator applies acting force, the sensor can synchronously detect micro-deformation or counter-acting force of the system in situ, and vibration isolation is better carried out.

The utility model relates to a fire fighting sand vehicle, and relates to the technical field of fire fighting. The fire fighting sand vehicle comprises a box body, a plurality of idler wheels, a valve element, a driving assembly and a limiting piece. The box body is provided with a sand storage cavity and a sand outlet communicated with the sand storage cavity; the plurality of rollers are rotatably arranged at the bottom of the box body; the valve core is movably arranged in the box body; the driving assembly is rotatably arranged at the bottom of the box body, and the driving assembly is used for driving the valve element to move in the height direction; the limiting piece is rotatably arranged on the side surface of the box body; in the sand laying state, the driving assembly drives the valve element to move in the direction away from the sand outlet hole in the height direction, and the limiting piece abuts against the driving assembly so that fire fighting sand in the sand storage cavity can flow out through the sand outlet hole. And in the sand storage state, the sand outlet hole is blocked by the valve element. According to the technical scheme, the labor intensity of fire fighting salad transportation can be relieved, the emergency rescue time efficiency is improved, and guarantee is provided for safety production of a gas recovery well station.

The utility model relates to the technical field of metamorphic robot, specifically disclose a multi -angle spacing's bionic metamorphic mobile robot, including support frame, its side surface fixedly connected with drive motor, the support frame is recessed type design, and the support frame inner wall is provided with transmission screw rod, both ends outer surfaces of transmission screw rod all install adjusting slide block. This multi -angle spacing's bionic metamorphic mobile robot, through transmission screw rod both ends reverse thread design, drive motor drives screw rod rotation, adjusting slide block synchronous reverse movement, through the linkage action of first linkage link and second linkage link, make spacing clamping plate realize open -and -close action, can adjust the clamping range according to object shape or environmental angle, the spring connection between support slide and support frame makes it elastic sliding when contacting object, drive the self -adaptation of the fitting baffle to adhere to irregular surface, cooperate hydraulic push rod and adjust two support frame spacing, realize multidirectional, multi -angle flexible spacing.

The present invention relates to the technical field of foundation pit drilling, and specifically proposes a construction equipment and method for bored pile foundation pits of building basements, including: a spiral drill bit and a reinforcement guide mechanism. The present invention cooperates with the spiral drill bit and the support column through the reinforcement guide mechanism, so as to provide support force for the middle part of the drill rod during the lifting and lowering movement of the spiral drill bit for drilling holes, thereby improving the stability of the spiral drill bit during rotation and downward movement, avoiding the spiral drill bit from tilting or deflecting due to centrifugal force during rotation, improving the quality of the spiral drill bit drilling, and automatically cleaning and guiding the soil on the spiral blades through the mud cleaning and discharge group when the spiral drill bit drives the soil to move upward, avoiding the problem of low efficiency and incomplete cleaning when manually cleaning the soil on the spiral blades in the traditional way, thereby realizing the integrated function of supporting and guiding the spiral drill bit during the working process and cleaning the soil on the spiral drill bit.

The utility model discloses a kind of inflatable mouth of tent or air cushion, including two ends opening inflatable pipe and being located in the deflation structure of inflatable pipe inside, the mounting base of inflatable pipe lower end outside is connected on tent or air cushion, inflatable pipe upper end outside is connected with gas nozzle cover;Inflatable pipe inside is equipped with spigot;The deflation structure includes connecting rod, baffle fixed in the bottom end of connecting rod and nut being connected in the top end of connecting rod, the connecting rod is inserted into spigot, flexible plug is sleeved on the connecting rod of baffle inboard, the flexible plug can be attached to inflatable pipe bottom end port;Two sides in spigot are equipped with sliding slot, the connecting rod both sides are equipped with sliding block, and the sliding block is slidably installed in sliding slot;Spring is abutted between nut and spigot.

This utility model belongs to the technical field of massage equipment, specifically relating to a calf massage mechanism and a foot massager. Through the worm gear and gear assembly formed between the output shaft of the drive motor and the gear components, as well as the linkage between the transmission shaft, eccentric protrusion, swing arm, and connecting rod, a novel composite massage transmission system is constructed. This system breaks through the limitations of traditional single rolling massage, simultaneously achieving surface rolling massage from the rollers and deep compression massage driven by the swing arm. The massage movements are richer, enabling comprehensive relaxation of the superficial fascia and deep muscles of the calf, solving the core problems of existing technologies such as limited massage methods and poor massage effects. Furthermore, integrating the aforementioned calf massage mechanism into a foot massager achieves a unified function of foot and calf massage, enriching the functional dimensions of the foot massager and enhancing the overall product's usability and market competitiveness.
