Abstract
The invention discloses a device for monitoring crack development. The device is characterized by being capable of monitoring crack extensive quantity and timely alarming when the crack development exceeds a set value. The device is composed of a baffle plate and a monitoring alarm device, wherein the monitoring alarm device is composed of a mechanical device and an alarm circuit. The mechanical device consists of a spring, a pushing rod, a guide rail and a slide block, wherein a metal screw is arranged on the slide block as a trigger switch. A circuit part is a series circuit consisting of a power supply, a power supply switch, a micro switch and a buzzer. The baffle plate and the monitoring alarm device are respectively arranged at the two sides of a crack, and are used for enabling a spring to be in a compression state while being fixed; when the crack on the wall is expanded, the spring in the compressed state pushes out the pushing rod and can be used for driving the slide block and the trigger switch fixed on the pushing rod to move together; and when the trigger switch touches the micro switch, the monitoring alarm device gives out an alarm. The crack monitoring alarm has the beneficial effects of being capable of timely and conveniently monitoring the development condition of the crack and alarming in advance when danger comes.
Description
Technical field
This patent is a kind of device of monitoring the crack development.It is characterized in that to monitor the crack extensive magnitude, and when the crack development surpasses setting value, in time report to the police.
Background technology
Present stage, there was the house of many rowlock wall load-bearing in China's part rural area, the masonry residential building that also has the no constructional column of a large amount of early stage construction in the city, on the bearing wall of these buildings the crack is arranged more, do not continue development as the crack, still comparatively safe, but when the sustainable development of crack, then no longer safe, just should in time withdraw.
The objective of the invention is to for avoiding bearing wall because of crack development unstability, and then cause house collapse, casualties, a kind of product is provided.
Summary of the invention
In order to monitor the development in crack, the utility model provides a kind of monitoring alarm, can monitor the extensive magnitude in crack, and when extensive magnitude reaches the numerical value of prior setting, just can report to the police.
The technical scheme that this patent adopts is made up of a baffle plate and monitoring alarm, and monitoring alarm is made up of mechanical hook-up and warning circuit.Mechanical hook-up is by spring, and push rod, guide rail, slide block are formed, and slide block is provided with one piece of metal screw as trigger switch.The series circuit that circuit part is made up of power supply, power switch, microswitch, hummer.The mechanical hook-up part: slide block set is on push rod, and tightening the metal screw can be fixed on slide block on the push rod.Guide rail is used for the restriction push rod, make its can be not up and down or about skew.Baffle plate and monitoring alarm are installed in the both sides, crack respectively, make spring be in compressive state in the time of fixedly, when crack on the wall enlarges, also corresponding expansion of distance between baffle plate and the device, the spring that is in compressive state will be released push rod, and drives slide block and the metal screw be fixed in the above and move together, when the metal screw touches microswitch, circuit is connected, and device is reported to the police.Subsidiary pointer can demonstrate the variable quantity in crack accurately on the metal screw, and in time reports to the police when reaching default alarming value.
The beneficial effect of this patent is can be in time and monitor the development in crack easily, reports to the police in advance when danger arrives.The mechanical part of this device except trigger switch and spring, is plastic material, and is with low cost.

I baffle plate among the figure, II monitoring alarm, 1 power supply, 2 hummers, 3 microswitches, 4 springs, 5 push rods, 6 slide blocks, 7 metal screws, 8 pointers, 9 guide rails.
Embodiment
Baffle plate and monitoring alarm are installed in the both sides, crack respectively.First fixing warning device, fixed dam more fixedly makes the spring of warning device be in compressive state during plate washer.
Unscrew the metal screw and make slide block move to predefined position at push rod, tighten metal key screw slide block and be fixed on the push rod.
When crack on the wall enlarges, also corresponding expansion of distance between baffle plate and the device, the spring that is in compressive state will be released push rod, and drives slide block and the metal screw be fixed in the above and move together, and subsidiary pointer can demonstrate the variable quantity in crack accurately on the metal screw.
When fracture width reached default alarming value, the metal screw touched microswitch, and circuit is connected, and device is in time reported to the police.
Claims (3)
1. monitor the crack development and timely device of reporting to the police when the crack development surpasses setting value for one kind.
2. the mechanical hook-up part is by spring, and push rod, guide rail, slide block are formed, and slide block is provided with one piece of metal screw as trigger switch, and device is reported to the police when trigger switch is run into microswitch.
