The patent was applied by Sanchuan Wisdom Technology Co., Ltd. and was authorized to be announced on May 17, 2017.
The figure is a schematic diagram of the structure of a meter protection device according to an embodiment of the present invention
Content Description
The utility model relates to the technical field of water meter equipment, in particular to a meter protection device and a water meter with the device.
Background of the invention
A large-caliber water meter is a water meter with a nominal diameter of 50 mm or more. In a large-caliber water meter, multiple sensors are usually installed inside a large-caliber water meter in order to detect the value of water pressure. Due to the large number of sensors used on large-diameter water meters, each sensor has its own leads. These leads are usually directly exposed outside the water meter and are easily damaged by humans or damaged during improper installation and use.
Summary of the Invention
The technical problem to be solved by the utility model is to provide a meter protection device and a water meter with the device, which can effectively protect the sensor and the lead wire, prevent it from being damaged or be disassembled by himself.
In order to solve the above technical problem, the utility model provides an instrument protection device comprising a pipeline, a sensor is installed in the pipeline, a protection plate is fixed on the sidewall of the pipeline, and the protection plate is correspondingly arranged outside the sensor. .
The figure is a schematic diagram of the structure of a meter protection device according to an embodiment of the present invention
Further, the protective plate is entirely attached to the side wall of the pipeline, and the head and tail joints and the middle portions are respectively fixed by fixing screws. The protection board includes a left half board and a right half board, and both ends of the left half board and the right half board are respectively oppositely connected. The left and right ends of the side wall of the pipeline are provided with a chute, and the left and right ends of the left half plate and the right half plate are correspondingly inserted into the chute, and can both slide along the chute. One end of the left half plate is sequentially connected to one end of the right half plate through a hinge, and the other end of the left half plate is detachably connected to the other end of the right half plate through a lock catch.
A data display mechanism is installed on the pipeline, the sensor is connected with a data display mechanism through a lead wire, and the protection board is correspondingly installed outside the lead wire. The data display mechanism is provided with a wire management mechanism, the wire management mechanism includes a baffle and a wire management hole, the baffle is fixed outside the data display mechanism, and the baffle is provided with a plurality of said principles. In the wire hole, one wire is correspondingly arranged in each of the wire management holes, and the protection board is correspondingly installed outside the wire management mechanism. The data display mechanism includes a circuit board and a display screen, the circuit board is connected with a display screen, and the sensor is connected with the circuit board through a lead wire. The left and right ends of the pipe are fitted with flanges.
The utility model also relates to a water meter, which comprises the meter guard device as described above. The above technical solution of the present invention has the following beneficial effects: The instrument protection device of the present invention includes a pipe, a sensor is installed in the pipe, and a protection plate is fixed on a sidewall of the pipe, and the protection plate is correspondingly disposed outside the sensor. The instrument protection device can effectively protect the sensors and their leads in the pipeline by adding a layer of protection plates outside the pipeline to prevent damage or unauthorized removal of the sensors. The instrument protection device has a simple structure and can greatly reduce the diameter of the large-diameter water meter pipeline. The difficulty of processing.
