The invention relates to an anticollision device of a shelf column. The anticollision device comprises a shell and an internal lining matched with the column, wherein the internal lining is located between the shell and the column, the shell comprises a side plate and a front baffle, the side plate is matched and connected with the column, the front baffle is blocked and connected with the side plate, and the internal lining is located between the side plate and the column. Because a fixed method independent of a column hole is utilized, the size variation of an upright protector is reduced as much as possible, flexible design combination for the widths of different columns and positions of supporting a beam or the column is adopted, thereby the problem of the poor adaptability of the majority of the traditional upright protectors on different columns is substantially overcome, and the upright protector is convenient for mounting and transportation. The anticollision device can attach to or semi-attach to the column, thereby saving space.

The movable fixture comprises a first connecting rod, a second connecting rod and a carrying plate; an electric telescopic rod and an inflation pump are arranged on the carrying plate; the electric telescopic rod is sleeved with a cylindrical air bag; the inflation pump is connected with the cylindrical air bag; rotating pins are arranged at the two ends of the carrying plate correspondingly; bearing seats paired with the rotating pins are arranged on the first connecting rod and the second connecting rod correspondingly; a coder and a steering engine are connected to the rotating pins at the two ends of the carrying plate correspondingly; the first connecting rod and the second connecting rod are fixedly connected with the coder and the steering engine correspondingly; and the electric telescopic rod, the coder, the inflation pump and the steering engine are all electrically connected with the PLC. According to the roll paper sorting device, paper tubes are not liable to be damaged in sorting work.

The invention relates to the technical field of fixed installation, and discloses a fixing device for robot motors, which includes a fixing seat and a clamping groove opened on the fixing seat, and a number of clamping plates are evenly distributed along the circumference of the clamping groove, and the clamping The plates are all horizontally slidably connected to the fixing seat, and there is a space for heat dissipation between two adjacent clamping plates; a number of hollow outer shafts are arranged on the fixing seat along its circumference, and the number of the outer shafts is the same as that of the clamping plates. The outer shafts are all rotatably connected with the fixed seats, and the inner shafts of the outer shafts are threaded and connected with the inner shafts fixedly connected with the clamping plate; the outer shafts are coaxially fixed with gears, and the fixed seats are slidably connected with racks meshing with the gears. The invention has a simple structure and can quickly clamp the motor to protect the motor and perform certain heat dissipation.

The invention relates to a method and a device for wirelessly reading a meter, in particular to a centralized type method and a device for unidirectionally and wirelessly reading a meter. The device comprises N slave stations, P main stations, K simulation front terminals and a management center; and each slave station consists of a remote transmission meter and a radio transmitter. The method comprises the following steps: performing direct sequence spread spectrum of data collected by the N slave stations according to preset pseudo-random codes; transmitting signals after spread spectrum and digital modulation on M carrier frequencies; for the main stations, performing down conversion and digitalization of the received signals on the K carrier frequencies; and performing matching despread-spectrum of the digitalized signals one after another by using L pseudo-random codes adopted by the spread spectrum of the slave stations to demodulate out data sent by the slave stations. In the invention, spread spectrum is applied to the signal transmission of wireless meter reading, so that the signal to noise ratio is greatly improved, and better penetrability and transmission distance under slim transmission power can be obtained; the main stations can manage more than thousands of slave stations; the unidirectional communication greatly reduces the cost and power consumption of slavestation equipment of the wireless meter reading system; and with the invention, the centralized reading can be rapidly popularized and applied.

The invention discloses a detection device for a capacitive liquid level sensor, specifically relates to the technical field of capacitive sensor detection, comprising a protective box and a supporting plate, the lower surface of the inner wall of the protective box is fixedly connected to the lower surface of a first box body , the lower surface of the inner wall of the protective box is fixedly connected with the lower surface of the inner wall of the second box. The present invention simulates the detection conditions in the case of large shaking by setting the first driving assembly, cam assembly, slide bar, toggle plate, second driving assembly, extrusion wheel, knocking rod and protective box, and at the same time the second driving assembly drives The squeeze wheel rotates to squeeze the moving plate, and then the third elastic component drives the knock rod to knock and vibrate the second box, simulating the testing conditions under vibration, and checking whether the testing results are consistent with the actual amount of liquid added. Consistent, the device can be used to simulate detection situations in various environments, and it is convenient to judge the influencing factors of the detection results and the detection accuracy and stability of the sensor itself.
