る。 Conventionally, when cleaning sample water sampling tubes, a cleaning device consisting of a bowl-shaped wiper attached to the washing end surface of a reciprocating cleaning rod is used to appropriately fix the sample water sampling tube to be cleaned and remove the sample to be cleaned. A cleaning rod is inserted into the water sampling tube from the open end and moved back and forth to mechanically remove contaminants adhering to the pipe wall. Since it is integrally connected to the driving force transmission shaft of the device that converts rotational motion into reciprocating motion, the component force in the direction perpendicular to the axial direction generated on the driving force transmission shaft is directly transmitted to the cleaning rod, so that the cleaning rod can move vertically or vertically. The sample water to be cleaned reciprocates inside the sample water collection tube while vibrating in the left and right directions, and the drive force transmission shaft and cleaning rod are deflected by their own weight. Due to reasons such as the fact that it is extremely difficult to connect the wiper directly to the pipe while maintaining a high degree of straightness, the inner wall of the sample water collection tube to be cleaned and the wiper do not come into uniform contact, resulting in deformation of the wiper and difficulty in cleaning. Not only will this cause non-uniformity, but there is also the risk of damaging the sample water collection tube to be cleaned. In particular, the longer the shaft length of these shafts and the cleaning rod, the greater the deflection of the driving force transmission shaft and the cleaning rod, and the greater the influence of the deflection becomes.

実現することを目的とする。 The present invention has an extremely simple structure, eliminates the influence of component forces in the axial direction and the right angle direction that occur on the drive force transmission shaft, and the influence of deflection of the drive force transmission shaft and cleaning rod, and achieves a high degree of processing precision in manufacturing. without requiring
It is an object of the present invention to realize a cleaning device that does not cause deformation of a wiper, nonuniform cleaning, or damage to a sample water collection tube to be cleaned, even when cleaning is performed in either a horizontal or vertical state.

Reference numeral 1 denotes a sample water sampling tube to be cleaned, and 2 a cleaning rod, each of which has a support hole 3 perpendicular to the central axis of the cleaning rod at its rear end. A bowl-shaped wiper 4 is made of rubber or a synthetic resin having appropriate elasticity, and is detachably attached to the tip end surface of the cleaning rod 2 by means of screws or the like. Reference numeral 5 denotes a driving force transmission shaft, which is formed of a hollow tube made of metal or hard synthetic resin, and has its rear end connected to a conventionally known device (not shown) for converting rotational motion into reciprocating motion. Reference numeral 6 denotes a support shaft of the cleaning rod 2, which is attached to the front end of the driving force transmission shaft 5 so as to be perpendicular to the central axis of the transmission shaft, and is inserted into a support hole 3 formed in the rear end of the cleaning rod 2. Then, the inner diameter of the support hole 3 is appropriately made larger than the outer diameter of the support shaft 6, and the overall outer diameter of the cleaning rod 2 is appropriately made smaller than the inner diameter of the driving force transmission shaft 5, or the cleaning rod The outer diameter of only the rear end portion of the cleaning rod 2, that is, the rear end portion inserted into the front end of the driving force transmission shaft 5, is appropriately reduced.
is formed to be rotatable around the support shaft 6 and swingable diagonally up and down or diagonally left and right. In addition, both ends of the support shaft 6 may be fixed to the tube wall of the driving force transmission shaft 5 by means such as caulking or welding, or the support shaft 6 may be formed with a bolt and fixed with a nut. Good too.

おそれは全くない。 In the present device, the driving force transmission shaft 5 and the cleaning rod 2 are not integrally connected, but the support shaft 6 and the support hole 3 are
Since the support shaft 6 and the support hole 3 are connected to each other through the support shaft 6 and the support hole 3, an appropriate play is provided between the support shaft 6 and the support hole 3, that is, an appropriate play is provided around the support shaft 6 and in the axial direction. The component force in the direction is the support shaft 6 and the support hole 3.
Even if the driving force transmission shaft 5 and the cleaning rod 2 are bent, the cleaning rod 2 will move around the support shaft 6 and diagonally up and down or diagonally left and right. Since it is freely rotatable, there is no risk of being affected by deflection, and therefore, the cleaning rod 2 can smoothly reciprocate within the sample water sampling tube 1 to be cleaned, which will cause deformation of the wiper 4 or uneven cleaning. There is no fear at all.

達軸と洗浄棒間に高度の真直度を要求されること
なく、真直度は全く無関係であるからその製作は
極めて容易である。 Furthermore, in the proposed device, there is no requirement for a high degree of straightness between the driving force transmitting shaft and the cleaning rod, unlike in conventional devices in which the driving force transmitting shaft and the cleaning rod are directly connected together, and straightness is completely irrelevant. Because of this, its production is extremely easy.
