PRIOR ART

BACKGROUND ART Conventionally, a combustion control device (the details thereof will be omitted since this itself is known) is used to measure the temperature and components of exhaust gas in a chimney. For measurement, the tip of the probe tube is inserted into a window installed in the chimney for detection, the exhaust gas is sucked and sampled from the tip, the amount of residual oxygen is measured with an oxygen sensor, and at the same time, the amount of residual oxygen is measured with a thermocouple etc. installed at the tip. The internal temperature was measured to measure the thermal efficiency of combustion equipment. The tip of the probe tube is required to be moved in accordance with the measurement position within the flue stipulated by the Air Pollution Control Act, and held for a predetermined period of time at each position. However, the chimney is not designed to hold the probe tube, so it must be held manually, or, since the chimney is heated to about 200 to 300 degrees Celsius, a strip of thin iron plate is wrapped around the outside of the chimney with a buckle. A probe tube holder was attached to this, and the probe tube wrapped in a thermal insulator such as asbestos was held in this holder.

[The problem that the idea attempts to solve]

By the way, the conventional probe tube holding means described above is unsuitable for long-term measurements when done manually and is prone to errors, and when it is fixed using a holder, it requires a large number of parts. It is expensive, and the length of the thin iron strip needs to be adjusted depending on the thickness of the chimney, which poses problems such as not being able to complete measurements in time when urgent measurements are required.

This idea was made to solve the above problems, and it is a probe tube holder that allows the probe tube to be easily held by hooking the holder with a hook into the chimney hole. The purpose is to obtain.

[Means to solve the problem]

The probe tube holder according to this invention is a holder for a probe tube whose tip end is inserted into the chimney to collect gas inside the chimney and detect the temperature inside the chimney, and is placed along the wall of the chimney. A hook part is provided on one side edge of the U-shaped base that is in contact with the through hole formed in the wall surface, and the base of the probe tube is attached to the through hole at a position corresponding to the hook part on the other side edge of the base. A holding part is formed on which the side is placed and held.

[Effect]

In this device, the base comes into contact with the wall by hooking the hook into the hole in the wall of the chimney, and installation is completed, and the tip end of the probe tube is inserted into the hole, and the base side is The probe tube is held by placing it on the holding part.

〔Example〕

Figure 1 is a configuration diagram showing an embodiment of this invention.
1 is a chimney, 2 is a wall of the chimney 1, 3 is a through hole of an arbitrary shape formed in the wall 2, and 10 is a combustion control device, which is composed of a sampling probe section 10A and a measuring instrument main body 10B. In the sampling probe section 10A, 11 is a probe tube, 12 is a thermocouple for detecting the temperature of the exhaust gas G, 13 is a suction port for sucking the exhaust gas G, and 14 is a probe tube 11 set at a required position in the chimney 1. A stopper 15 is a set screw for the stopper 14, 16
17 is a filter drain for removing dust and water from the sucked exhaust gas G; 18 is an exhaust gas introduction pipe for the exhaust gas G; 19 is a cable for the thermocouple 12. .

21 is a probe tube holder according to this invention that holds the probe tube 11, and FIGS. 2a, b, and c show a plan view (direction A), a front view (direction B), and a perspective view in the attitude shown in FIG. shows. 22 is the base of the probe tube holder 21; 23 is the base 2;
2, 24 is an L-shaped hook portion formed on the one side edge 23, 25 is the other side edge of the base 22, and 26 is a holding portion formed on the other side edge 25. The piece 27 is a concave holding portion for holding the probe tube 11 on the holding piece 26. Although the cross-sectional shape of the chimney 1 may be round or square, FIG. 1 shows a case where the wall surface 2 is square and has a flat surface.

Probe tube holder 21 configured as above
When in use, the probe tube holder 21 is set by hooking the hook 24 of the probe tube holder 21 into the through hole 3 as shown in FIG. Next, the probe tube 11
Set the stopper 14 at a position corresponding to the set position of the tip of the probe tube 11 in the chimney 1, fix it with the set screw 15, and then remove the probe tube 11.
After inserting the distal end of the probe tube 11 into the through hole 3 until it comes into contact with the stopper 14, the base side of the probe tube 11 is placed on the holding portion 27 to be held. In this state, the probe tube 11 receives a counterclockwise rotational moment about the holding portion 27 as a fulcrum, but the rotation is prevented by the stopper 14 inserted into the through hole 3 and is held.

[Effect of idea]

As explained above, this device is a holder for a probe tube whose tip end is inserted into a chimney and which collects gas inside the chimney and detects the temperature inside the chimney. A hook part is provided on one side edge of the letter-shaped base to hook into a through hole formed in the wall surface, and the base side of the probe tube is placed at a position corresponding to the hook part on the other side edge of the base. Since a holding part is formed to hold the probe tube holder, the hooking part of the probe tube holder can be attached to the through hole regardless of the thickness of the chimney. Further, since the structure is simple, it has advantages such as being inexpensive.
