Description

201014118 VI. Description of the Invention: [Technical Field] The present invention relates to an electric actuator in which an electric motor for driving a valve is disposed in a casing. [Prior Art] Conventionally, an electric actuator has been used for opening and closing a rotary valve or a linear motion valve used in an air conditioner or a mechanical device. In such an electric actuator, various electrical components and mechanical parts, such as an electric motor and a speed reduction mechanism, are usually disposed in one casing, and the output shaft is protruded from a casing in which the various electrical components and mechanical parts are disposed. In addition, a conduit is provided in the casing for introducing a wire connected to an external power source and a signal line for outputting a valve opening signal. Further, such an electric actuator is attached to a valve provided with a valve body and is embodied as an electric control valve. At this time, the output shaft of the electric actuator and the valve shaft of the valve body (the shaft for fixing the valve body shaft) are coupled via a joint. In addition, the casing of the electric actuator is bolted to the valve. Further, when the electric actuator is integrated with the valve and becomes an electric adjustment valve, it is conceivable to be installed outdoors, and a waterproof structure for preventing penetration of rainwater or the like into the casing can be employed. For example, the following waterproof structure is adopted: the electric actuator is mounted above the valve, considering that rainwater or the like falls from the ± square of the casing, that is, it is considered to receive rainwater by using the top surface of the casing, and the machine-like roof In the case of the surface, the opening is not provided. (Patent Document 1 is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. 2000-33-7551. Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei.

The actuator is mounted below the valve. A In this case, the bottom surface of the casing faces upward, and the upper side is replaced by Μ*· τ* a / machine and the bottom surface receives rainwater, so the rain passes through the gap between the output shaft and the casing or the green 糸 wire The gap between the tube and the wire penetrates into the inside of the casing, thereby deteriorating the internal parts. In addition, even in the field where the electric control valve is installed with a normal makeup shape, the vibration of the machine (the vibration of the fluid from the external UB 4 and the flow of the valve through the valve) has a large influence on the site. When the vibration is loosened and the posture of the electric actuator is changed from the initial state to the right state, the state of the electric actuator is ignored, and the battery is deformed or damaged by the wheel of the electric actuator. In the case of the installation of the second and second actuators, etc., the maintenance of the motor is not particularly noticed. When the maintenance personnel who went to the site at the operation m confirmed the 201014118, it was found that the cause of the malfunction was an abnormal installation of the electric actuator. For the purpose of inspection, PI k is provided with a humidity sensor in the casing in Patent Document 2 to detect the infiltration of water into the casing, and the condition of Μ ^ ^ is cleared. At this time, if water penetrates into the casing, the temperature inside the casing rises, and the inside of the casing becomes a state of high temperature and humidity. The humidity sensor was used to detect the high moisture state of the dish, and it was judged that water was infiltrated into the casing. In addition, in this method, although it is possible to detect the infiltration of rainwater into the casing, the front part does not know that rainwater may infiltrate.

In addition, it is impossible to detect the rain infiltration machine (4) until the temperature is high in the machine. In addition, no countermeasures against damage caused by changes in the mounting posture of the electric actuator were taken. In addition to the patent document 2, there is an electric drive device that takes a table against the water in the casing (for example, refer to Patent Documents 3 and 4), but the electric drive devices are all taken for condensation generated inside the casing. The device of the countermeasures cannot be dealt with in the case of infiltration of rain from the outside. Further, similarly to the document 2, no measures against the damage caused by the change in the mounting posture of the electric actuator were taken. The present invention has been made in order to solve the above problems, and an object of the present invention is to provide an electric actuator which can be used in advance to detect that damage may occur due to the infiltration of rainwater or the change in the mounting posture. In order to achieve the above object, an electric actuator is provided, in which an electric motor for driving a valve is disposed in a casing, and a tilt angle sensor is disposed in the casing for measuring electric actuation The tilt angle 丨 transmitting means of the device transmits the information about the mounting posture of the electric actuator ^ obtained based on the tilt angle measured by the tilt angle sensor to the external device. According to the invention, the tilt angle of the electric actuator is measured by a tilt angle sensor provided in the casing, and information on the mounting posture of the electric actuator obtained based on the tilt angle is transmitted to the outside. For example, in the present invention, the tilt angle measured by the tilt angle sensor is transmitted to the external device as information on the mounting posture of the electric actuator. At this time, the maintenance person can know the installation posture of the electric actuator from the transmitted inclination angle, and if the installation posture of the electric actuator is reversed, it can be judged that the rainwater may infiltrate, and if the actuator is mounted, If there is a big change, it can be judged that the output shaft and the valve shaft may be deformed or damaged. In the present invention, the information on the mounting posture of the electric actuator obtained from the tilt angle measured by the tilt angle sensor is not limited to the tilt angle measured by the tilt angle sensor. For example, 'can be set: the normal installation posture storage means, the normal installation posture related information of the electric drive is stored as a normal installation posture; the current ampoule posture creation means, the electric actuator is based on the inclination angle measured by the inclination angle sensor The current installation posture related information is the purpose of: the installation posture; and the installation posture determination means, comparing the normal installation posture with the current installation posture to determine the normal/abnormality of the current installation posture of the electric actuator; The result of the shirt is transmitted to the external device as information on the mounting posture of the electric actuator.
