  Conventionally, for measuring the temperature of an object to be measured or an object to be monitored, for example, a temperature recording device and a temperature record management system of a power transmission facility, temperature is detected at a predetermined time interval, and the measured value is stored in a history memory as a history. A temperature recording apparatus has been proposed (see, for example, Patent Document 1).

  However, according to the conventional temperature recording device, in the attachment to the measurement object, it is not possible to fix to the glass or the like because it is fixed using an attachment member such as a screw, and not only a tool is required, There is a problem that it takes time and effort when there are a large number of attachment points or when it is necessary to attach or detach due to maintenance inspection or the like. In particular, in a narrow place or high place, the use of tools or the like may be dangerous because an operator may be forced to take an unnatural posture. In addition, when fixing using a mounting member such as a screw, the temperature recording device and the outside air are not sufficiently shut off, so that it is easily affected by the ambient temperature, and high-precision measurement cannot be performed.

  In addition, when attaching a temperature recording device to an object to be measured using a suction cup, the suction position on the object to be measured is not constant due to changes in the pressing force on the object to be measured. There was a problem that the temperature recording device could not be attached to the object to be measured at a certain distance from the surface, the measurement accuracy varied, and stable temperature measurement could not be performed.

  Therefore, the object of the present invention is that it can be fixed in a place where it has not been conventionally attached without using a tool, etc., and the temperature recording device can be easily and reliably attached and is not easily affected by the ambient temperature, and the measurement accuracy It is an object of the present invention to provide a suction holder for a temperature recording apparatus that enables stable temperature measurement without causing variations.

  In order to achieve the above-mentioned object, the present invention measures the temperature of a measurement object and holds a temperature recording device for storing the measurement data in a storage unit as necessary, and adsorbs and fixes the measurement object to the measurement object. An adsorption holder for a temperature recording apparatus, comprising: a positioning unit that sets a distance from the temperature recording apparatus to the measurement object to be a predetermined distance. provide.

  In the above-described invention, the suction holder may include a grip portion having a hollow portion communicating with a dome portion formed on the suction side.

  In order to achieve the above object, the present invention holds a temperature recording device that measures the temperature of a measurement object and stores the measurement data in a storage unit as necessary, and adsorbs the measurement object on the measurement object. An adsorption holder that is fixed to the temperature recording apparatus, wherein the adsorption holder includes an abutting unit that presses the temperature recording apparatus against the measurement object with a predetermined force. An adsorption holder is provided.

  In the above invention, it is desirable that the contact means generate a pressing force smaller than the suction force generated by the suction holder.

  According to the suction holding tool of the temperature recording apparatus of the present invention, the distance to the measurement object can be easily set at a constant distance. Accordingly, the temperature recording device can be easily attached to and detached from the measurement object, and the temperature measurement of the measurement object can be performed stably and accurately.

(First embodiment)
(Configuration of adsorption holder of temperature recording device)
1A and 1B are cross-sectional views according to the first embodiment, in which FIG. 1A is a state before the suction holder is fixed to a measurement object, and FIG. 1B is a measurement target of the suction holder. It is a figure which shows the state adsorbed and fixed to the thing. The suction holding tool of the temperature recording device according to the present invention includes a suction cup body 1, an outer peripheral edge portion 2 provided around the outer periphery thereof, a grip portion 3, and a temperature recording device 40 mounted on the suction surface side of the suction cup body 1. It has a temperature recording device mounting portion 4 that can be formed and a positioning portion 5 that is formed on the suction surface side of the suction cup body 1.

  The suction cup body 1 and its outer peripheral edge 2 are formed of an elastic material such as silicon rubber. The outer peripheral edge 2 is a portion that comes into contact with the suction surface 11 when sucked to the suction surface 11 that is the surface of the measurement object 10, and forms a dome shape before being sucked. Form. The grip portion 3 has a hollow portion 3a having a hollow inside, and the hollow portion 3a is connected to the dome portion 20 by at least one communicating portion 3b, and has a structure capable of moving air. The temperature recording device mounting portion 4 is formed as a hole that fits the temperature recording device 40 to the extent that the temperature recording device 40 does not easily fall off after the temperature recording device 40 is mounted.

  The positioning portion 5 is formed on the suction surface 11 side, and the end portion 5a that contacts the suction surface 11 side of the positioning portion 5 does not protrude toward the suction surface 11 side than the end portion of the outer peripheral edge portion 2, and The temperature recording device 40 mounted on the temperature recording device mounting portion 4 is positioned so as to protrude from the temperature sensing surface 40a toward the suction surface 11 side. The positioning portion 5 is formed between the outer peripheral edge portion 2 and the temperature recording device 40 at a position in the radial direction from the center of the suction cup body 1, but may be continuously formed in a circumferential shape. , May be provided in a state where a part thereof is not continuous. Further, the positioning portion 5 does not have to be formed integrally with the suction cup body 1, and may be formed by attaching another member to the suction cup body 1.

(Operation of adsorption holder of temperature recording device)
The temperature-sensitive surface 40a of the temperature recording device 40 is mounted on the temperature recording device mounting portion 4 with the suction surface 11 side, and the suction cup body 1 is measured while holding the grip portion 3 and reducing the air in the cavity 3a. Press against the suction surface 11 of the object. At this time, as shown in FIG. 1B, the suction cup body 1 and the outer peripheral edge 2 are elastically deformed, and the end 5a of the positioning part 5 is pressed against the suction surface 11, and the suction cup body 1 While the volume of the dome portion 20 is reduced, the outer peripheral edge portion 2 comes into close contact with the suction surface 11. Based on the elastic restoring force of the suction cup main body 1 and the outer peripheral edge portion 2, when trying to return to the shape before adsorption, the capacity of the dome portion 20 tends to increase in the absence of inflow of air from the outside air. The atmospheric pressure is smaller than the external atmospheric pressure. As a result, the elastic restoring force and the force due to the atmospheric pressure difference between the external pressure and the dome portion 20 are balanced, and the suction cup body 1 is attracted to the suction surface 11. In this case, with the outer peripheral edge 2 in close contact with the suction surface 11, the end portion 5 a that is in contact with the suction surface 11 side of the positioning portion 5 temporarily returns to the shape before the suction by the elastic restoring force. However, since the grip portion 3 is removed from the hand at the final stage of the suction operation, diluted air flows from the dome portion 20 into the cavity portion 3a, and the atmospheric pressure of the dome portion 20 further decreases. Thus, the end portion 5 a is not separated from the suction surface 11 and is sucked while being in contact with the suction surface 11. That is, the suction holder is adsorbed to the measurement object 10 when the air pressure of the dome portion 20 of the suction cup body 1 is lower than the air pressure of the dome portion 20 of the suction cup body 1.

  Here, the positioning unit 5 presses the suction cup body 1 against the suction surface 11 of the measurement object 10, thereby sucking the end portion 5 a while being in contact with the suction surface 11. It is not pressed and fixed to the side. Accordingly, the temperature-sensitive surface 40a of the temperature recording device 40 is positioned and attached at a position separated from the suction surface 11 by the value D shown in FIG. The value of D can be set from the depth of the concave portion of the temperature recording device mounting portion 4 and the thickness of the temperature recording device 40. That is, considering the positioning unit 5 as a reference, the value of the above D is obtained by designing and manufacturing the depth of the concave portion of the temperature recording device mounting portion 4 in consideration of the thickness of the temperature recording device 40 from the positioning unit 5. Can be set. The value of D can be set arbitrarily, and this value can be made substantially constant except for errors such as manufacturing. The value of D is determined from the relationship between the temperature sensing surface 40a of the temperature recording device 40 and the adsorption surface 11 of the measurement object, and the temperature measurement data of the temperature recording device 40 and the temperature of the adsorption surface 11 of the measurement object 10 are previously determined. Measurement data and temperature measurement data of the required part such as the center temperature of the measurement object are measured, and various corrections are made when analyzing the data after temperature measurement, so that it is attached by the suction holder of the present invention. By using the temperature measurement data of the temperature recording device 40 thus obtained, the temperature data of the required part of the measurement object 10 can be obtained.

(Effect of adsorption holder of temperature recording device)
According to the first embodiment of the present invention, it is possible to easily fix a glass or the like where it has been difficult to fix conventionally without using a tool or the like. In addition, the temperature recording device can be attached and detached easily and reliably, and since the temperature recording device 40 is mounted inside the suction cup body 1, the temperature recording device is not easily affected by the outside air or the ambient temperature, and does not vary in measurement accuracy. It is possible to provide an adsorption holder for a temperature recording device that enables measurement. That is, the temperature recording device 40 can be attached and detached with a simple operation while maintaining a certain distance from the measurement object 10. Thereby, stable and accurate temperature measurement data of the measurement object can be obtained, and temperature data of a part required by the measurement object can be obtained using this data.

The suction holder is attracted to the object to be measured by the pressure inside the dome shape of the suction cup body 1 being lower than the air pressure of the dome portion 20 of the suction cup body 1. The outer peripheral edge 2 is deformed by the close contact operation to the suction surface 11, and the temperature sensitive surface 40 a of the temperature recording device 40 contacts the suction surface 11 of the measurement object 10.
