The utility model relates to a battery cell assembly and electronic equipment, the battery cell assembly comprises a battery cell shell, a battery cell and an early warning circuit, the early warning circuit is located in the battery cell shell, the battery cell shell is further provided with a battery cell accommodating cavity, the battery cell accommodating cavity is used for placing the battery cell, and the early warning circuit is used for being connected with the placed battery cell. The first connector is selectively in a first connection state or a second connection state; when the battery cell is placed in the battery cell containing cavity in the first direction, the battery cell is connected to the early warning circuit, the early warning circuit is in a first connection state, and an early warning prompt is given out. And when the battery cell is placed in the battery cell accommodating cavity along a second direction, the early warning circuit is in a second connection state and does not give out an early warning prompt, and the first direction is opposite to the second direction. According to the invention, automatic detection and alarm functions can be realized when the battery cell is reversely inserted, so that the safety and accuracy of battery cell installation are improved, the situation that normal operation of the electronic equipment is influenced or even the electronic equipment is damaged due to wrong installation of the battery cell can be effectively prevented, and meanwhile, the use safety of the electronic equipment can be improved.

The utility model discloses an embodiment of a kind of steel wire rope strand detection device, including strand receiving piece, guide piece, mounting seat, limit sheet, monitoring rod and strand detector.Strand receiving piece is used to contact and transmit the force generated when steel wire rope strand passes;Guide piece is fixedly connected with it and passes through mounting seat, and end connects limit sheet;Monitoring rod is arranged in parallel with guide piece on limit sheet;Strand detector is used to detect the position change of monitoring rod.The device monitors the state of lifting steel wire rope in real time, triggers alarm as soon as strand occurs, can effectively prevent steel wire rope fracture and stacker goods falling accident, guarantee safety production.

This utility model discloses a diaphragm rupture alarm device for a diaphragm metering pump, relating to the field of diaphragm rupture alarm technology. The device includes a pressure gauge connected to the first end of a tee via a first double-threaded nut. The second end of the tee is connected to a venting and draining assembly. The third end of the tee is connected to a valve guide sleeve via a second double-threaded nut. The valve guide sleeve has a valve ball guide hole that communicates with the interior of the tee. The valve guide sleeve is connected to an air / liquid inlet assembly, which is connected to the diaphragm metering pump. This invention solves the problem that existing pressure gauge-type alarm devices are inconvenient for implementing venting and draining functions.

The utility model belongs to the technical field of ultrafiltration energy-saving devices, and particularly relates to an ultrafiltration energy-saving device broken belt detection device which comprises a base, a sleeve is fixedly connected to the interior of the base, a sliding rod is slidably connected to the interior of the sleeve, a mounting plate is fixedly connected to the upper end of the sliding rod, a limiting ring is fixedly connected to the interior of the sleeve, and the limiting ring is fixedly connected to the interior of the base. The limiting ring is slidably connected with the sliding rod, a spring is arranged in the sleeve, the lower end of the base makes contact with an alarm, and a button is arranged at the upper end of the alarm. According to the utility model, the alarm function is realized by additionally arranging the alarm. Meanwhile, the guide wheel, the spring and other components are arranged, when the belt is broken, the spring can drive the guide wheel to trigger an alarm button, and the alarm rapidly gives an alarm. Therefore, the breakage condition of the belt can be perceived at the first time, and the problem that normal operation of the ultrafiltration energy-saving device is affected due to the fact that the driving belt is prone to breakage is effectively solved.

The utility model relates to the technical field of heat supply devices, and discloses a heat supply energy-saving multi-mode heat supply device which comprises a heat supply device body, a multi-channel valve is arranged in the heat supply device body, a first heat pipe is fixedly installed at one end of the multi-channel valve, and a second heat pipe is fixedly installed at the other end of the multi-channel valve. Connecting pipes are arranged on the two sides of the heat supply device. Through the arrangement of the multi-channel valve and the two groups of heat pipes in the heat supply device, a worker can respectively or simultaneously supply heat through the first heat pipe and the second heat pipe, so that the heat supply is energy-saving, and the steam can flow in the pipeline when the steam flows in the pipeline. The gas tightness between the circulating pipe and the connecting pipe is detected in real time by sealing the pipeline joint through the rubber protective sleeve, when the pipeline joint is abraded and leaks gas, the gas can enable the alarm to give out whistling sound through the alarm, the alarm function is achieved, and workers can be prevented from being scalded while maintenance is provided for the workers.

The utility model relates to a rail cab apron which comprises a main body frame, an anti-skid panel embedded in the main body frame and fixed bottom corners arranged at the four corners of the bottom of the main body frame. The main body frame is a rectangular frame formed by welding hollow profiles on four sides, and a supporting beam is arranged in the rectangular frame; a clamping groove is formed in the upper end of each fixed bottom corner, and the section bars at the four corners of the main body frame are clamped to the fixed bottom corners; a fixed connecting part is arranged at the outer end of the lower part of each fixed bottom corner, and the fixed connecting parts are connected with a rail steel rail through fasteners; lighting, alarming and protecting units are arranged on the peripheral side walls outside the main body frame; the rail cab apron solves the problem that a sight blind area is generated during operation of a traditional cab apron, the operation condition of personnel above the cab apron and the operation condition of personnel at the bottom of a pit can be visually observed, and potential safety hazards generated during cross operation are prevented; compared with an existing cab apron, the service life is prolonged, the operation safety coefficient is improved, the personnel operation risk is reduced, and the operation security function is fundamentally achieved.
