The invention belongs to the technical field of monitoring cameras, and is specifically a method for testing a school monitoring camera, comprising: S1, installing the camera to be tested in a test device, and connecting the camera to be tested to a signal viewing port; S2, performing a test on the camera to be tested Rain test, and obtain the rain test result; S3, carry out the impact test of the camera to be tested while the rain test, and obtain the impact test result; S4, judge the test result of the camera to be tested according to the rain test result and the impact test result ; The side of the storage case is provided with a number of air intake holes. The test method of the school surveillance camera is to adjust and move the shot blasting mechanism through the ring guide rail and the electric slider, so as to perform impact tests on the camera to be tested at various angles, and cooperate with the electric turntable to adjust the ring guide rail to achieve Treat the test camera to a full crash test.

The invention discloses an alarm device for intelligent fire extinguishing equipment, which belongs to the technical field of alarm devices and comprises an alarm box and a box door. The interior of the alarm box is fixedly installed with a box control panel, and the side wall of the alarm box is fixedly equipped with a moisture collection mechanism; the present invention can realize automatic moisture collection by setting a moisture collection mechanism on the outside Function, the collected water will be effectively stored, through the design of the physical structure, through the use of physical phenomena during the operation and shutdown of the device, it can realize automatic water collection for secondary use, powerful functions, and a dredging and cleaning component for the water collection tank It can effectively cooperate with the moisture collection mechanism to realize the automatic cleaning process of the smoke sensor and temperature sensor on a regular basis, without manual management, and maintain the use effect of the smoke sensor and temperature sensor.

The invention relates to a wall knocking sound wave detection device, which includes a vehicle body, a knocking unit, a sensor unit and a controller, wherein: the knocking unit is arranged on the vehicle body, and includes a drive assembly, an elastic action assembly and a knocking unit sequentially connected by transmission. block, the driving component acts on the elastic action component through rotation, and drives the elastic action component to move, so that the knocking block hits the wall once in a working cycle and bounces up. The sensor unit is arranged on the vehicle body, including the acoustic wave sensor and the sensor The lifting component, the sensor lifting component drives the acoustic wave sensor to drop to fit the wall before the knocking block hits the wall, and drives the acoustic wave sensor to reset after the knocking is completed. Compared with the prior art, the present invention uses a motor to drive the elastic action assembly to move, and drives the knocking block to knock on the wall, each time the knocking force is constant and adjustable, and the sound wave is collected and detected by the sound wave sensor close to the wall, so that The detection is reliable and accurate.

The invention discloses a remote monitoring system for medical equipment based on a communication network. Its structure includes a communication signal pole, a monitoring eye shell, a night vision lamp, an automatic focus knob, a camera, a rotating disk, a housing, a sound amplification hole, a fixed base, Suction cup fixing mechanism, the suction cup fixing mechanism is located at the bottom of the front end of the casing, the casing and the suction cup fixing mechanism adopt clearance fit, the disk fixing mechanism consists of a transmission shaft, a first gear, a screw rod, a rocker, a rocker plate, a push rod, and a push block, horizontal connecting rod, rack, vertical connecting rod, transmission sliding rod, transmission rope, second gear, pressing rod, piston rod, first telescopic spring, piston block, piston pipe, through pipe, second telescopic spring, Suction cup, the user does not need to ask a professional installer to install it, and the user can install it by himself, and it is easy to install, strong in fixing performance, and convenient to disassemble. The user only needs to operate a rocker, which saves installation time and also Does not affect the beauty of the wall after dismantling.

The invention relates to an ejection type dispensing module of a glue dispenser, comprising a rubber outlet tube and a rubber extrusion sleeve slidingly sleeved outside the rubber outlet tube; when the rubber outlet tube moves toward the head of the rubber outlet tube relative Extrude the rubber tube radially to make the glue come out from the head; there are several piezoelectric shrapnels evenly arranged outside the head of the rubber outlet tube; The glue drop is ejected to its front; the ejection type dispensing module of the dispenser uses the high viscosity of the glue itself to decompose the dispensing process into extrusion and elastic, combining the advantages of the two methods to achieve faster , More stable and more accurate glue and viscose, to avoid glue dragging, drawing, etc., the pressure required for glue is small, and the viscose has wide applicability, which is conducive to dispensing operations for various parts with complex structures.

The invention discloses a hanging pendulum buffer device of a pendulum impact testing machine. The hanging pendulum buffer device comprises a rack and a pendulum, wherein a buffer device is arranged between the pendulum and the rack. The hanging pendulum buffer device is characterized in that the buffer device comprises a rocking arm, an electromagnetic controller and a hook tongue, wherein mounting holes are respectively formed in the middle and the two ends of the rocking arm; the middle of the rocking arm is hinged on the rack; one end of the rocking arm is hinged with an electromagnetic controller, and the other end of the rocking arm is hinged with a hook tongue; the upper end of the hook tongue is a hook working point, and the lower end of the hook tongue is a impact buffer point; the upper end of the hook tongue is matched with a hook on the pendulum; and the impact buffer point at the lower end of the hook tongue abuts against a hydraulic buffer. The the hydraulic buffer serves as a buffer element in the hanging pendulum buffer device, and according to the structure of the hydraulic buffer, the fit clearance between a piston and the inner surface of a cylinder body is properly controlled, so that the phenomenon that the movement of the piston is out of nimbleness and not flexible can be avoided. Through a buffer action of the hydraulic buffer, the problems that the joggling and the collision of the hanging pendulum can be radically solved, and thus the stability and no-impact of the hanging pendulum are realized.
