Description

  The present invention relates to a configuration of a multi-stage water temperature measuring apparatus that can measure the water temperature at multiple positions in the vertical direction in water as desired regardless of fluctuations in the water level.

  Conventionally, as a general water temperature measuring device for measuring the temperature of water in a reservoir such as a dam, for example, an anchor block is submerged in the bottom of the pond and has a surplus length that can cope with fluctuations in the water level assumed from the anchor block. A configuration has been adopted in which a check line is extended, a float on the water surface side is moored, and a rod-like water temperature sensor extending toward a predetermined measurement depth in water is provided on the float.

  In the case of such a configuration, the water temperature at the predetermined depth portion can be easily measured by the rod-shaped water temperature sensor extending from the float portion toward the predetermined measurement depth portion in water.

  However, in the case of a water temperature measuring device having such a configuration, it is not possible to appropriately cope with fluctuations in the water level, and when the water level fluctuates, the float floats down and the check line becomes slack, so that There was a problem that could not be measured. When the check line is loosened, there is a disadvantage that the float flows under the influence of the wind and the vertical position itself changes.

  Therefore, in order to solve such a problem, in the above-described configuration, for example, a pulley is attached to the float side, and the leading end side of the trajectory extending from the anchor block is U-turned downward via the pulley, By providing a balance weight, a water temperature measuring device has been proposed in which the float properly follows fluctuations in the water level, and the anchor line from the anchor block does not loosen and is always maintained at a constant tension. (For example, refer to the configuration of Patent Document 1).

  In the configuration of the water temperature measuring device, for example, a first water temperature sensor (water temperature measurement 1 m below the water surface) and a second water temperature sensor (water surface) having different lengths (measurement depths) extending from the floating part toward the water. The water temperature is measured at a vertical position of a plurality of stages (two stages).

  In such a configuration, even if the water level fluctuates, the float properly follows the fluctuation of the water level due to the action of the pulley, and the balance weight acts to constantly maintain a constant tension without slackening the check line from the anchor block. Since it is maintained in the maintained state, the problem that the float cannot sink and the check line is slackened and the water temperature cannot be measured at the exact set position as in the configuration of the conventional general water temperature measuring device is solved.

  Further, the flow of the float due to the influence of the wind can be suppressed by the tension value of the check line corresponding to the weight value of the balance weight.

Japanese Utility Model Publication No. 5-3952

  By the way, in the measurement of water temperature in the above lakes, etc., in order to establish a muddy water inflow model for studying measures to prevent prolonged muddy water in dam reservoirs and to grasp the diffusion status of red tide organisms, details at the same point in the reservoir It is necessary to acquire continuous measurement data of vertical water temperature distribution.

  In light of such technical problems, when the configuration of Patent Document 1 is viewed, the float follows the fluctuation of the water level due to the action of the pulley, and the check line from the anchor block does not loosen due to the action of the balance weight. Since it is maintained in a state where a certain tension is maintained, it is possible to prevent the float from sinking and the check line from sagging. Further, the flow of the float due to the influence of the wind can be suppressed by the tension value of the check line corresponding to the weight value of the balance weight.

  However, in the case of the configuration of Patent Document 1, the water temperature sensors that measure the water temperature at a plurality of water depths are provided on both sides of the float part and have a length (measurement depth) extending from the float part toward the water. It consists only of a different first water temperature sensor (water temperature measurement 1 m below the water surface) and a second water temperature sensor (water temperature measurement 3 m below the water surface).

  Therefore, it is not possible to measure the water temperature in multiple steps at a predetermined interval over the entire surface from the surface layer to the low layer of the reservoir at the same vertical position at a specific point. It can only measure the water temperature (1m and 3m below the surface).

  Moreover, since these 1st, 2nd water temperature sensors are provided in the both sides of the float, a measurement point differs mutually and it does not become the measurement in the same vertical position.

  Further, since the water temperature sensor is provided in the float itself, it is easily affected by wind and waves acting on the float, and the measurement point and measurement depth (vertical position) are likely to fluctuate.

  The present invention has been made to solve such a conventional problem, and includes two sets of water temperature measuring devices, a water temperature measuring device for measuring the water temperature of the upper layer portion and a water temperature measuring device for measuring the water temperature of the lower layer portion. Combining a water temperature measuring device in combination with each other and providing a water level change absorbing function, the entire vertical region of the reservoir from the surface layer to the lower layer is measured at the same vertical position at a predetermined measurement point regardless of the water level. It is an object of the present invention to provide a water temperature measuring device that can measure water temperature in multiple stages at predetermined intervals.

For this purpose, the present invention comprises the following effective problem solving means.
(1) The problem-solving means of the invention of claim 1 The problem-solving means of the present invention can cope with fluctuations in the water level, the first anchor member submerged in the pond bottom, the first float floating on the water surface, and the like. A first check member for mooring the first float to the first anchor member with a surplus length, and a first water temperature provided in multiple stages in the vertical direction in the upper layer region of the first check member A first water temperature measuring device that measures the water temperature of the upper layer of the reservoir, a second anchor member submerged in the bottom of the pond, a second float that floats on the water surface, and responds to fluctuations in the water level. A second checker member that anchors the second float with the second anchor member with a possible extra length, and a second step provided in multiple stages in the vertical direction in the lower layer region of the second checker member A second water temperature measuring device comprising a water temperature sensor for measuring the water temperature in the lower layer of the reservoir The first check member of the first water temperature measuring device is configured such that the upper layer region where the first water temperature sensor is provided is constituted by a wire member and the lower layer region is constituted by a chain member, The second check member of the second water temperature measuring device is made of a wire member, and the tip of the second float side of the wire member is fed out for a predetermined length via a pulley provided on the second float. The weight member is provided at the tip of the feeding portion.

  According to such a structure, the chain member in the 1st tracking member of the 1st water temperature measuring apparatus which measures the water temperature of a reservoir upper layer part is a weight with respect to the wire member part which provided the 1st water temperature sensor in the vertical direction in multiple stages. Thus, it functions as a tension maintaining means for maintaining the tension. Moreover, even if the water level drops, the chain member is freely folded at the lower side according to the drop in the water level, and maintains its function as a weight without slacking like a wire member, and serves as a means for absorbing changes in the water level. Also works. The same is true when the water level rises.

  Therefore, the wire member portion provided with the water temperature sensors in multiple stages is always maintained in an appropriate vertical state. As a result, each first water temperature sensor can accurately measure the water temperature of each part of the upper reservoir region.

  In addition, the second check member of the second water temperature measuring device that measures the water temperature of the lower layer of the reservoir is a wire member as a whole, and the second water temperature sensor is provided in multiple stages in the vertical direction in the lower layer region. The wire member provided with the second water temperature sensor is always applied with a constant tension regardless of the fluctuation of the water level by the weight member at the tip end of the wire member that maintains the tension via the pulley. Maintained in a state.

  Therefore, the water temperature of each part of the lower layer area that cannot be measured by the first water temperature sensor of the first water temperature measuring device is accurately measured by the second water temperature sensor of the second water temperature measuring device.

As a result, according to the above configuration, the water temperature of each part in the vertical multi-stage part over the entire region from the upper layer part to the lower layer part of the reservoir is accurately measured.
(2) Problem solving means of the invention of claim 2 The problem solving means of the invention is the problem solving means of the invention of claim 1, wherein the wire member and the second checking member constituting the first checking member are arranged. Each of the constituting wire members is provided with a child wire member arranged in parallel so as to be relatively movable via a ring member, and first and second water temperature sensors are attached to the child wire members.

According to such a configuration, the wire member constituting the first check member and the wire member constituting the second check member are maintained in their original state, and the corresponding child wire member is simply pulled up. The first and second water temperature sensors can be recovered very easily.
(3) Problem Solving Means of Invention of Claim 3 The problem solving means of the present invention is the object solving means of the invention of claim 1, wherein the first water temperature measuring device is different from the first float. A float is provided, and a first water temperature sensor for measuring the water temperature of the surface layer portion using the float is installed.

  As in the problem solving means of the first aspect of the present invention, for the first check member of the first water temperature measuring device, the upper layer region where the first water temperature sensor is provided is the wire member, and the lower layer region is When configured as a chain member, the first float tends to sink by a predetermined depth due to the weight of the chain member. Accordingly, in the first water temperature sensor of the wire member portion, it becomes difficult to detect the water temperature of the surface layer portion.

However, if a floating body different from the first floating body is provided as described above and the first water temperature sensor for measuring the water temperature of the surface layer portion is installed using the floating body, such a problem is surely achieved. Can be resolved.
(4) Problem solving means of the invention of claim 4 The problem solving means of the invention is the problem solving means of the invention of claim 1, 2, or 3, wherein the second water temperature measuring device includes a second float. In addition to the above, a third float away from the second float is provided, a second pulley is provided on the third float, and the upper end side of the second check member is suspended.

  The tension adjustment and length adjustment corresponding to the water level change of the second cable member can be performed only with the pulley of the second float part. However, in that case, the second cable member and the child wire member that extend from the lower second anchor member portion to the upper pulley portion and are folded back from the upper side to the lower counterweight in the same pulley portion are entangled with each other. Thus, not only the tension adjustment and the length adjustment according to the water level change are made impossible, but also the lifting of the child wire member for collecting the water temperature sensor is made difficult.

  On the other hand, a third float separated from the second float is provided separately from the second float as described above, and a second pulley is provided on the third float, and the second check line is provided. When the upper end side (count weight side) of the member is drooped, first, it extends from the lower second anchor member portion to the upper pulley portion, and is folded back from the upper side to the lower counter weight direction in the pulley portion. The second cable member is once extended by a predetermined distance in the horizontal direction, and then is lowered by the counterweight via the second pulley portion, and the second float and the third The length adjustment dimension corresponding to the water level change can be ensured by the distance between the floats, and the length of the cable member suspended downward from the second pulley can be shortened.

  As a result, the second cable member and the child wire member, which extend from the lower second anchor member portion to the upper pulley portion and are folded back from the upper side to the lower counterweight in the pulley portion, are entangled with each other. The problem is definitely solved. Also, the child wire member can be easily pulled up.

  In order to realize such an effect more reliably, more specifically, in order to maintain a constant distance between the second float and the third float, the second float and the third float are They are connected to each other via a connecting rod having a predetermined length.

  Further, in the case of such a configuration, in order to prevent the second cable member and the child wire member from the first pulley portion to the second pulley portion and the second wire member from being entangled with each other, the first and second A configuration in which each pulley section is a two-unit type equipped with first and second ropes is also adopted as necessary.

  As described above, according to the configuration of the present invention, it is possible to accurately measure the water temperature of each part of the vertical multi-stage part over the entire region from the upper layer part to the lower layer part of the reservoir without being affected by the fluctuation of the water level. It becomes like this.

  As a result, the present invention provides a detailed water temperature vertical distribution at the same point in the reservoir for constructing a muddy water inflow model for studying measures to prevent prolonged muddy water in a dam reservoir, and grasping the diffusion status of red tide organisms, etc. It is suitable for continuous measurement data acquisition.

  Hereinafter, with reference to FIGS. 1 to 6 of the accompanying drawings, the configuration and operation of a multi-stage water temperature measuring apparatus according to an embodiment of the present invention will be described in detail.

<Schematic configuration of the entire device>
First, FIG. 1 shows a schematic configuration of the entire multi-stage water temperature measuring apparatus according to the embodiment of the present invention. The multi-stage water temperature measuring apparatus according to the embodiment of the present invention includes a first anchor member (anchor block) 2 submerged in a pond bottom 1 portion of a reservoir, and a first levitation installed on a water surface 3 portion of the reservoir. Floating element (buoy) 4, first guiding member 5 for anchoring the first floating element 4 to the first anchor member 2 with a surplus length that can cope with fluctuations in the water level, and the first guiding member 5 A first water temperature measuring device 7 for measuring the water temperature of the reservoir upper layer area A, and a pond bottom 1, comprising first water temperature sensors 6, 6. The second anchor member 8 submerged in the part, the second float 9 buoyed and installed on the water surface 3 part, and floated and installed on the water surface 3 part in a state linked to the second float 9. The second float 50 has a surplus length that can cope with fluctuations in the water level. The second checker member 10 for mooring the third floats 9 and 50 to the second anchor member 8 and the second checkered member provided in multiple stages in the vertical direction in the lower layer region B of the second checker member 10 It consists of water temperature sensors 11, 11... And comprises two sets of water temperature measuring devices including a second water temperature measuring device 12 that measures the water temperature in the lower reservoir region B.

  That is, the multistage water temperature measuring apparatus according to the embodiment of the present invention is based on the water depth corresponding to the water storage amount of the reservoir, and the measurement area is divided into upper and lower measurement areas A and B. There are provided two sets of water temperature measuring devices, a first water temperature measuring device 7 that measures the water temperature of the upper layer region A and a second water temperature measuring device 12 that measures the water temperature of the lower layer region B. By combining these, the water temperature in the entire desired water depth region from the upper layer region to the lower layer region corresponding to the amount of water stored in the reservoir can be measured (see the state of FIG. 1). ).

  Therefore, the length from the first float 4 to the first anchor member 2 of the first check member 5 of the first water temperature measuring device 7 and the second check member 10 of the second water temperature measuring device 7 are described. The length from the second float 9 to the second anchor member 8 is the length corresponding to the maximum water depth corresponding to the maximum amount of water stored in the reservoir (the length from the upper end to the lower end). It is set to be. In addition, the first check member 5 of the first water temperature measuring device 7 is adjusted in length and maintaining tension corresponding to a change in water depth using the chain member 5b as described below. The second tracking member 10 of the second water temperature measuring device 12 has a length corresponding to a change in water depth using the third float 50, the first and second pulleys 13 and 44, and the counterweight 14 as described below. It tries to maintain adjustment and tension.

<Configuration of the first feeder member 5 in the first water temperature measuring device 7>
As for the 1st tracking member 5 of the said 1st water temperature measuring apparatus 7, the upper layer area A part in which the said 1st water temperature sensors 6, 6, ... were provided is a lightweight wire member 5a, and the lower layer area B is weight. It is comprised by the chain member 5b with. For example, as shown in FIG. 3, the wire member 5a and the chain member 5b are engaged with the ring portion formed at the lower end portion of the wire member 5a so as to be relatively rotatable in the direction around the axis. The U-shaped engagement ring 15 at the upper end portion on the chain member 5b side, which is configured in a straight line, is engaged with each other and integrally connected to each other, thereby constituting one traverse member as a whole.

  As a result, the first feeder member 5 has an upper layer area A side wire member 5a portion where the first water temperature sensors 6, 6,... Are attached and a lower layer region B side chain member 5b portion has a balance weight ( Function as a weight member). In addition, the chain member 5b has a chain structure, and even if the water storage amount is reduced and the water level is lowered, each ring part is folded to the pond bottom 1 one after another without any sag. The balance weight function is maintained, and the tension (extended state) of the wire member 5a provided with the first water temperature sensors 6, 6,. Therefore, the conventional problem does not occur.

  The upper end of the wire member 5a and the hook portion 4a at the lower end of the float 4 are, for example, as shown in FIG. 2, a straight engagement piece 16a similar to the engagement ring 15 on the chain member 5b side in FIG. And a U-shaped engagement ring 16 having a pivotal connection in the direction around the axis.

<Attachment structure of first water temperature sensors 6, 6 ... in the wire member 5a>
Incidentally, as described above, the first water temperature sensor 6, 6... Is provided in a multistage structure at a predetermined interval in the vertical direction at the wire member 5 a portion. , 6... Are attached as follows.

  That is, a predetermined ring member 17 is engaged with an engagement piece 16 a of an engagement ring 16 that connects the upper end of the wire member 5 a and the hook portion 4 a at the lower end of the float 4. The upper end of the child wire member 19 arranged in parallel to the wire member 5a as the parent wire member is connected via the attachment ring 18 that can be engaged and disengaged. A large number of water temperature sensors 6, 6... Are attached at predetermined intervals. The length from the upper end to the lower end of the child wire member 19 corresponds to the length of the wire member 5a which is the parent wire member, and a counterweight 35 is provided at the lower end.

  On the child wire member 19 side, a pair of upper and lower caulking members 19a and 19b as shown in FIG. 4, for example, are provided at a predetermined interval between the water temperature sensor mounting portions. By binding the first side binding member (insulok) 6a, the upper end side of the main body of the water temperature sensor 6 is locked. Moreover, the lower part side of the water temperature sensor 6 main body is locked by binding the second binding member (insulok) 6b on the lower end side of the water temperature sensor 6 main body to the lower part of the child wire member 19.

  The child wire member 19 having the multiple first water temperature sensors 6, 6 attached to the multi-stage structure in this way is connected via guide rings (carabiners) 20, 20. The wire member 5a is engaged in a loosely fitted state. Reference numeral 21 denotes a fixing member that crimps the guide rings 20, 20... To a predetermined position of the child wire member 19 via a ring member (double phosphorus) 22.

  Thereby, in a state where a large number of first water temperature sensors 6, 6,... Can be pulled up and hung independently from the wire member 5a, as shown in FIG. 1, along the wire member 5a, It is suspended in multiple stages in the vertical direction. And the water temperature in each water depth position is measured.

<About the water temperature measurement structure of the surface layer part in the 1st water temperature measurement apparatus 7>
In the configuration of this embodiment, the float 4 is always subjected to a settling load due to the weight of the chain member 5b described above. And, it fulfills the function of appropriately maintaining the tension of the wire member 5a and the child wire member 19 regardless of the fluctuation of the water level. However, it also increases the amount of submergence of the float 4 compared to the case where it is not. As a result, the water temperature sensor 6 located at the uppermost end of the child wire member 19 is also submerged in a deep position accordingly, and the water temperature of the surface layer portion that is originally desired to be measured cannot be measured as it is.

  Therefore, in this embodiment, as shown in FIGS. 1 and 2, for example, a ring member 23 is provided on the engagement piece 16a of the engagement ring 16 that connects the float 4 to the wire member 5a and the child wire member 19. A small float 25 is provided at the tip of an arm 24 of a predetermined length that is connected to be freely pivoted up and down via the, and a grandchild wire attachment ring 26 is further provided at the tip of the float 25. The upper end of the grandchild wire 28 is connected through a connecting ring 27 that can be engaged and disengaged.

  And the 1st water temperature sensor 6 for measuring the water temperature of a surface layer part similarly to the case of the said child wire member 19 is provided in this grandchild wire 28 part. Further, a counterweight 29 for maintaining the suspended tension is provided at the lower end of the grandchild wire 28.

  According to such a configuration, the small float 25 can maintain free buoyancy without being affected by the weight of the chain member 5b described above, and the first water temperature sensor 6 for measuring the surface layer water temperature. Can be always located in the surface layer part near the water surface 3, and a water temperature can be measured.

<Installation of auxiliary floats 34 and 32 to prevent submersion during water temperature data collection>
In the above configuration, reference numerals 34 and 32 are auxiliary floats for preventing submergence at the time of collecting water temperature data, and upper end portions of the child wire member 19 and the grandchild wire 28 via flexible wires 33 and 31 having predetermined lengths, respectively. It is connected to.

  In the configuration of this embodiment, the first water temperature measurement sensors 6, 6... Maintained in the installation state of FIG. 1 for a predetermined period of time are used to lift the child wire member 19 to which the first water temperature measurement sensors 6, 6. The data is pulled up and collected, and each data is checked and recorded. However, if you release your hand in the middle of the pulling up, the first water temperature sensor 6, 6,... That was being pulled up will sink again, making it difficult to move the ship for a new pulling up. It involves a lot of work.

  However, if there is an auxiliary float 34 as shown in the figure, it can be lifted up again at the same position. Therefore, the pulling work becomes easy. This effect is exactly the same in the case of the auxiliary float 32 on the first water temperature sensor 6 side that measures the water temperature of the surface layer portion.

<Configuration of Second Check Member 10 in Second Water Temperature Measuring Device 12>
On the other hand, the second checking member 10 of the second water temperature measuring device 12 is entirely composed of the same (one) wire member, and the second floating member 9 side of the second checking member 10. The tip extends long in the horizontal direction opposite to the orthogonal direction via the first pulley 13 provided on the lower side of the second float 9, and further, the second provided on the lower side of the third float 50. A counterweight 14 for adjusting the length and maintaining the tension is provided at the lower end of the hanging portion.

  The second and third floats 9 and 50 are connected to each other via a connecting rod 47 having a predetermined length so as to be freely movable. The second and third floats 9 and 50 and the first floats 9 and 50 are connected to each other. By the action of the second pulleys 13 and 44 and the counterweight 14, the length from the second float 9 portion of the second tracking member 10 to the second anchor member 8 portion corresponding to the water depth change of the reservoir Adjustment and tension can be maintained.

  And as for the said 2nd check member 10 which consists entirely of a wire member, from the upper end side of the lower layer part area B side part to the lower end side is an attachment part of the said 2nd water temperature sensor 11, 11, .... The second water temperature sensors 11, 11,... Are attached as will be described later. The appropriate tension state is maintained by the counterweight 14 via the first and second pulleys 13 and 44 that absorb the water level change.

<Connection structure between the first and second pulleys 13 and 44 and the second and third floats 9 and 50>
By the way, the connecting ring 46 at the upper end of the first pulley 13 and the hook portion 9a at the lower end of the second float 9 are, for example, U-shaped having a straight engagement piece 45a on the lower side as shown in FIG. It is connected via an engagement ring 45 so as to be freely rotatable relative to the axis. Further, the connecting ring 49 at the upper end of the second pulley 44 and the hook portion 50a at the lower end of the third float 50 are also U-shaped having straight engaging pieces 48a on the lower side, as shown in FIG. It is connected via an engagement ring 48 so as to be freely rotatable relative to the axis.

  The second and third floats 9 and 50 are connected to each other in the horizontal direction along the water surface 3 via the connecting rod 47 having a predetermined length as described above. Ring members 47a and 47b are provided at both ends of 47, and these are fitted to the engagement pieces 45a and 48a of the U-shaped engagement rings 45 and 48 on the second and third floats 9 and 50 side. It is connected. Therefore, although the relative movements of the first and second pulleys 13 and 44 are also free, the relative positions and distances of the first and second pulleys 13 and 44 are properly restricted to a constant relationship by the connecting rod 47 at all times. Has been.

  Therefore, the distance between the first pulley 13 and the second pulley 44, that is, the length of the second check line member 10 between the first pulley 13 and the second pulley 44, the second pulley 44. The total length of the second drafting member 10 from the first pulley 13 combined with the length of the second drafting member 10 tip from the bottom to the lower side is also premised on the maximum water depth of the reservoir. Therefore, it is possible to set and regulate appropriately considering the water level change. Naturally, the length of the connecting rod 47 is also set to a desired length in consideration thereof.

  By the way, in the case of this embodiment, the connecting rod 47, together with the second and third floats 9 and 50, increases and decreases the adjustment distance corresponding to the water level change of the second cable member 10 depending on the length thereof. Earning is made not in the direction but in the horizontal direction, so that the drooping length of the second cable member 10 downward from the second pulley 44 is made as short as possible.

  Of course, it is possible to adjust the tension and length of the second cable member 10 only with the first pulley 13 of the second float 9 portion. However, in that case, it is only necessary to make tension adjustment and length adjustment impossible by entanglement between the second check members 10 folded back from above to below and from above to below, and the child wire members 40 from each other. However, it is difficult to pull up the water wire sensor 40 for recovery.

  However, as described above, the third float 50 separated from the second float 9 is provided separately from the second float 9, and the second pulley 44 is provided on the third float 50, so that the second float When the upper end side (counting weight 14 side) of the feeder member 10 is roped, first, the lower second anchor member 8 part extends to the upper first pulley 13, and the first pulley 13 part The second cable member 10 folded back from the upper side toward the lower counterweight is once extended in the horizontal direction by a predetermined distance, and then is lowered by the counterweight 14 via the second pulley 44. In other words, the distance between the second float 9 and the third float 50 can effectively secure the length adjustment dimension corresponding to the change in the water level, and the rope suspended downward from the second pulley 44. To shorten the length of the wire member as much as possible Kill (see the state of FIG. 1, FIG. 5).

  As a result, the second cable line extends from the lower second anchor member portion 8 to the upper first pulley 13 and is folded back from the upper side toward the lower counterweight 14 in the first pulley 13 portion. The problem that the member 10 and the child wire member 40 are entangled with each other is surely solved. Further, the water temperature sensors 11, 11,... Can be easily pulled up for recovery.

<Structure of the first and second pulleys 13 and 44>
In the case of this embodiment, the first and second pulleys 13 and 44 include first and second sets of ropes 13a, 13b, 44a and 44b, as shown in FIG. In addition, the two-sided type is adopted, the first side of the first rope 13a, 44a is used for guiding the second guide member 10, and the second side of the second rope 13b, 44b is described later. The water temperature sensors 11, 11,... Are used for guiding the child wire member 40.

  If comprised in this way, when the water level fluctuates and the 2nd check member 10 and the subwire member 40 move up and down according to it, a guide ring will be attached to the 2nd check member 10 and the 2nd check member 10 concerned. The child wire members 40 juxtaposed (arranged) via 20, 20,... Are smoothly guided independently without being entangled with each other.

<Attachment structure of second water temperature sensors 11, 11..
As described above, the second water temperature sensors 11, 11...
