The utility model discloses a liquid level float switch, which comprises a shell, a liquid level switch, a liquid level switch and a liquid level switch, the anti-reverse groove is formed in the shell; the fixing frame is inserted into the anti-reverse groove, and a storage area is arranged in the fixing frame; the steel balls are arranged in the storage area; the ballasting iron sand is arranged in the shell; the microswitch is arranged at the top of the fixing frame, and a cable of the microswitch sequentially penetrates through the ballasting iron sand and the bottom of the shell; the waterproof cover covers the fixing frame and the microswitch and is inserted into the ballasting iron sand; the epoxy resin fixes the waterproof cover, the ballasting iron sand, the fixing frame and the shell together. According to the utility model, the transparent special-shaped positioning waterproof cover is additionally arranged, so that water and gas can be prevented, a short-circuit fault caused by tin whiskers can be prevented, the top of the waterproof cover can be prevented from pressing a circuit through the positioning design of the waterproof cover, and the installation consistency is realized. And the problem of switch failure caused by reverse installation of the float switch is also solved.

The invention discloses an auxiliary device for armless disabled people, and relates to the technical field of brain-computer interfaces. In order to solve the problems that in the prior art, an invasive type and a semi-invasive type of existing wearable auxiliary devices for providing life assistance for people with upper limb disability need surgical operation, electrodes are implanted into the cerebral cortex, but the surgical risk is large, complications such as infection and bleeding are possibly caused, and long-term maintenance is needed after implantation; in order to solve the technical problems that a non-invasive interbrain interface is relatively small in risk, convenient to use, simple to operate, low in cost and relatively low in control precision, the technical scheme provided by the invention is as follows: the auxiliary system for the armless disabled person comprises a brain signal acquisition module for acquiring an electroencephalogram signal of a user in a non-invasive manner; the visual control module is used for collecting target object positioning information; and the main control module is used for generating grabbing action group signals according to the signals acquired by the brain signal acquisition module and the visual control module. The auxiliary grabbing device is suitable for being applied to auxiliary grabbing work of the arm-free handicapped.

The invention discloses a motor home multi-drive feedback control system, and relates to the technical field of motor home drive, and the motor home multi-drive feedback control system comprises an interaction end and an execution end; the interaction end comprises a user interaction module, an environment sensing module and a network communication module, and the interaction end obtains an instruction needing to be executed through the user interaction module, the environment sensing module and the network communication module and transmits the instruction to the execution end through a communication bus; the user interaction module comprises a control device which is used for providing an operation interface and a control mode for a user. According to the multi-drive feedback control system for the motor home, through mutual cooperation of the interaction end and the execution end, the problem of electrical appliance failure caused by failure of a drive scheme can be solved through a standby drive scheme, and fault reasons are rapidly judged through series connection of input feedback and output feedback.

A magnetic flap liquid level meter, including water tank, the top of the water tank is equipped with the first taper mouth, the top of the water tank is equipped with the third pulley and the fourth pulley, the recess of the third pulley and the fourth pulley is contacted with one end of the transmission rod, prevents the transmission rod from being inclined, the other end of the transmission rod is contacted with the circular annular recess of the first pulley and the second pulley;The top of the first pulley and the second pulley are fixedly connected with the air pipe. The liquid level meter realizes non-contact measurement with the liquid level through ingenious structure design and working principle, and has good anti-freezing performance, and can work stably in low temperature environment.
