Description

  The present invention relates to a pipe mount sensor mount for fixing a sensor for measuring a water level or a flow rate of a fluid flowing in a pipe pipe such as a sewer pipe in the pipe pipe.

  Conventionally, a sensor S of a pressure-type water level meter for measuring the level of sewage flowing in a vertical pipe (for example, a sewage pipe) K is a pipe mount sensor mount (hereinafter referred to as a mount) as shown in FIG. It is used by being attached to the lower upper surface of 51 (refer to Patent Document 1).

  The mount 51 has a substantially arcuate vertical cross section and has a shape in which the upper part is notched (opened). The mount 51 is inserted into the tube rod K in a state of being elastically deformed in the diameter reducing direction, and is pressed against the inner wall of the tube rod K by a restoring force acting in the diameter expanding direction after the insertion, thereby being fixed to the tube rod K. It will be in the state. When the mount 51 is removed from the pipe rod K, the mount 51 may be elastically deformed in the diameter-reducing direction by using two gripping portions 52 extending from both open ends toward the lower side (inner side). It is detachable from the inner wall of the tube K.

Utility Model Registration No. 32007086

  However, since the mount 51 is inserted and fixed to the tube rod K solely depending on the elastic restoring force, there remains anxiety about the stability of the fixed state. Specifically, the mount 51 may be detached from the pipe rod K in a situation where an extreme water pressure other than normal is applied. Therefore, if the elastic restoring force is increased in order to increase the stability of the fixed state, a large force is required to reduce the diameter of the mount 51 when inserting and fixing to the tube rod K, resulting in a problem that workability is reduced. .

  The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide a tube rod sensor mount that can be easily fixed to the tube rod and can improve the stability of the fixed state. There is.

  In order to achieve the above-mentioned object, a tube mount sensor mount according to the present invention is a tube mount sensor mount for fixing a sensor for measuring a water level or a flow rate of a fluid flowing in the tube tube. A pair of opposed end portions that are separated in the circumferential direction by a dividing groove and formed in a strip shape having a substantially circular shape with a longitudinal section divided, and are opposed to each other across the dividing groove at a position facing the dividing groove. The formed flexible band, and inserted into the dividing groove so as to be able to advance and retreat in the axial direction perpendicular to the circumferential direction of the tensile band, both left and right sides abut against the set of opposing ends, A restricting piece configured such that a distance between the pair of opposed end portions expands / contracts as it enters / retreats into the dividing groove, and extends across the set of opposed end portions. Are slidable on the tension band. And Tagged connecting band Ri, the said restriction piece is provided over a connecting band, and and a moving mechanism for moving the the regulating piece in the axial direction (claim 1).

  In the tube rod sensor mount, the moving mechanism is threadedly engaged with the male screw and a shaft that extends in the axial direction and has a male screw and a shaft that is provided with an interval in the axial direction provided on an outer surface. A stand provided with an internal thread, and a slider that is passed through the shaft so as not to come out between the two protrusions and is slidable on the shaft. The slider may be fixed to one of the connecting bands (Claim 2).

  According to the present invention, a tube mount sensor mount capable of enhancing the stability of the fixed state while being easily fixed to the tube tube is obtained.

  In other words, the pipe rod sensor mount of the invention according to each claim of the present application is to reduce and expand the diameter by operating the moving mechanism to advance and retract the restricting piece with respect to the dividing groove. When mounting, the regulating piece is retracted to a certain extent from the dividing groove to reduce the diameter, and then inserted into the pipe rod.After the insertion, the moving mechanism is operated to insert the regulating piece into the dividing groove to expand the mount. What is necessary is just to make it diameter, and this can make it easy to fix to a pipe rod, and can also improve the stability of the fixed state.

  Embodiments of the present invention will be described below with reference to the drawings.

  A pipe rod sensor mount (hereinafter referred to as a mount) 1 according to the present embodiment measures a water level or a flow rate of a fluid flowing through a vertical pipe rod (for example, a sewer pipe) K as shown in FIG. For fixing the sensor S for the inside of the tube K (lower part).

  First, the outline of the mount 1 will be described. The mount 1 is formed of a material having corrosion resistance and rust resistance (for example, a metal such as stainless steel), has a substantially circular longitudinal section, and has a reduced diameter. The tube is inserted into K and expanded in diameter after insertion, thereby being brought into pressure contact with the inner wall of the tube rod K, thereby being fixed to the tube rod K. The sensor S is attached to the lower upper surface of the mount 1. Normally, the sensor S is attached to the mount 1 before the mount 1 is fixed to the tube K.

  On the other hand, the sensor S of this example constitutes a pressure-type water level gauge, has a cylindrical appearance, has a sensor pressure-receiving surface S1 on one end side, and has a main body S2 used in a horizontal orientation, and a main body S2. A streamlined head S3 having a length of about 8 cm whose base end is detachable on one end side and a cone-shaped head S4 having a length of about 3 cm detachable on the other end of the main body S2 are provided. The cone-shaped head 4 is installed on the upstream side with the downstream side facing. The main body S2 is configured to accommodate a battery, a memory, a base, etc., not shown, and to transmit and receive data by removing the cone-shaped head S4 and connecting a communication cable.

  Hereinafter, details of the configuration of the mount 1 will be described.

  As shown in FIGS. 1 to 3, the mount 1 includes a tension band 2 that can be stretched so that the outer peripheral surface can be brought into contact with the inner wall of the tube rod K. In order to enable such a tension, the tension band 2 has flexibility. The tension band 2 is divided in the circumferential direction by a dividing groove 3 (see also FIG. 8), and is formed in a belt shape having a substantially circular shape with a longitudinal section divided.

  As shown in FIGS. 2 and 3, a pair of opposed end portions 4 that are opposed to each other with the dividing groove 3 interposed therebetween are formed at positions facing the dividing groove 3 in the tension band 2. FIG. 4 is an exploded view showing an unfolded state (a state unfolded in a plane) of each member constituting the mount 1, and as shown in FIG. 4, the opposing end 4 is a periphery of the body 5 of the tension band 2. It is composed of a direction end 6, a spacer 7 joined to the inner peripheral surface of the circumferential end 6, and a guide piece 8 joined to the spacer 7.

  Here, in FIG. 4, three black circles respectively shown in the circumferential end portion 6, the spacer 7, and the guide piece 8 indicate mutual joint portions. As is clear from these joint portions, the spacer 7 is The guide piece 8 is joined to the circumferential end 6 at a position away from the tip, and the guide piece 8 is joined to the spacer 7 so that the tip matches the tip of the circumferential end 6. The longitudinal section of the tip of the end 4 is bifurcated (see also FIG. 8).

  As shown in FIGS. 3, 5, 6, and 8, the mount 1 can also advance and retract in the axial direction (X direction shown in FIG. 3) perpendicular to the circumferential direction of the tension band 2 with respect to the dividing groove 3. A restriction piece 9 to be inserted is provided. In the restricting piece 9, the left and right sides 9a and 9b are in contact with the pair of opposed end portions 4 and 4, and at least one of the left and right sides 9a and 9b (both in this example) is oblique with respect to the axial direction (X direction). Extend to.

  In this example, the left and right sides 9a, 9b of the regulating piece 9 are inserted into the gap between the circumferential end 6 of the opposing end 4 and the guide piece 8, respectively, and come into contact with the spacer 7 at the back thereof. The left and right ends of the restriction piece 9 are guided by the pair of opposed end portions 4 and 4. The regulating piece 9 can be advanced and retracted in the axial direction (X direction) with respect to the dividing groove 3 while being guided by the opposing end portion 4.

  Further, as shown in FIGS. 2, 5, and 8, the regulating piece 9 is a member having a plate shape whose longitudinal section is curved in an arc shape, and as shown in FIG. The left and right sides 9a and 9b are inclined so as to be symmetric, and the left and right widths are narrowed from one end to the other end. The tip of the spacer 7 that receives the contact between the left and right sides 9 a and 9 b is also inclined so as to correspond to the inclination angle of the left and right sides 9 a and 9 b of the regulating piece 9. In this example, the circumferential end 6 and the tip of the guide piece 8 are also inclined in the same manner as the tip of the spacer 7.

  As shown in FIGS. 3, 6, and 8, the mount 1 further extends over a pair of opposing ends 4, 4, and both ends are slidably attached to the tension band 2. It comprises. As shown in FIG. 4, the connecting band 10 includes a main body 11 and a loop forming body 12 joined to both left and right ends of the main body 11.

  As shown in FIG. 2, the main body 11 has a plate shape whose longitudinal section is curved in an arc shape, and as shown in FIG. 4, the main body 11 has a substantially rectangular plate shape when expanded in a plane. As shown in FIGS. 7A and 7B, the loop forming body 12 has a bent plate shape, and a gap (loop) is formed between the loop forming body 12 and the main body 11. It is comprised so that the main body 5 of the tension band 2 can be passed through (refer FIG.3, FIG.5, FIG.6). In FIG. 4, black circles shown at four places on the left and right sides of the main body 11 and two places on the loop forming body 12 indicate joint places.

  As shown in FIGS. 3, 5, and 6, the mount 1 is also provided across the restricting piece 9 and the connecting band 10, and includes a moving mechanism 13 for moving the restricting piece 9 in the axial direction (X direction). It has.

  The moving mechanism 13 of the present example is provided with an external surface that extends in the axial direction (X direction) and has a male screw 14 (see FIG. 1) and two projecting portions 15 that are spaced apart in the axial direction (X direction). A shaft 16, a stand 17 provided with a female screw (not shown) that engages with the male screw 14, and a shaft 16 that is held through the shaft 16 so as not to come out between the two protrusions 15, 15. The stand 17 is fixed to one of the restricting piece 9 or the connecting band 10 (the connecting band 10 in this example), and the slider 18 is fixed to the other (the restricting piece 9 in this example). ing.

  Here, the male screw 14 is provided over substantially the entire shaft 16. The protruding portion 15 protrudes outward in the diameter direction of the shaft 16 and is configured as a large diameter portion in which the diameter of the shaft 16 is increased in this example. In this example, a slider 19 having the same configuration as the slider 18 is fixed to the restriction piece 9 and is slidable on the shaft 16. Furthermore, a hexagonal portion 20 for rotating operation is provided at one end of the shaft 16.

  In the moving mechanism 13 of this example, when the hexagonal portion 20 is rotated around its axis using, for example, an appropriate tool, the shaft 16 is screwed with respect to the stand 17 and is provided on the shaft 16. When the shaft 16 is screwed in a state where the protruding portion 15 is in contact with the slider 18, the restricting piece 9 is interlocked with the shaft 16 via the protruding portion 15 and the slider 18 and moves in a predetermined direction. This movement is performed more smoothly by providing the slider 19 in addition to the slider 18.

  The diameter of the mount 1 (stretch band 2) changes depending on the position where the restricting piece 9 stops. The mount 1 is reduced in diameter as the entry of the restricting piece 9 into the dividing groove 3 becomes shallower. 1 is expanded in diameter.

  Therefore, when the mount 1 is attached to the pipe rod K, the restricting piece 9 is retracted to some extent from the dividing groove 3 to reduce the diameter, and is inserted into the pipe rod K in that state. 20) may be operated to allow the restricting piece 9 to enter the dividing groove 3 to expand the diameter of the mount 1. Here, when the mount 1 is inserted into the tube rod K, a handle or the like is provided on a part of the mount 1 (for example, the regulating piece 9) so that the mount 1 does not enter the tube rod K. 1 may be held.

  In the mount 1 of the present example having the above configuration, it is possible to improve the stability of the fixed state while being easily fixed to the tube rod K. That is, the mounting time of the mount 1 can be shortened, and the time allowance for this leads to the improvement of the local work quality. In addition, shortening the time in dangerous places such as manholes contributes to ensuring the safety of workers. In addition, it can be expected to reduce the inconvenience of local residents.

  Moreover, in the mount 1 of this example, since the component which has a complicated mechanism is not used for the moving mechanism 13, the manufacturing cost can be reduced by that much. Moreover, the operation of the moving mechanism 13 (hexagonal portion 20) can be performed using a general-purpose tool, and eventually the mount 1 can be installed and removed by the general-purpose tool. Moreover, the mount 1 can be installed even under running water.

  It should be noted that the present invention is not limited to the above-described embodiment, and can be variously modified and implemented without departing from the gist of the present invention. For example, the following modifications can be given.

  The sensor S is not limited to the one having the above configuration, and may be a flow meter, for example.

  In the above embodiment, the tension band 2 is divided in the circumferential direction by one dividing groove 3, but may be divided in the circumferential direction by a plurality of dividing grooves 3, and in this case, in each dividing groove 3, If the opposing end 4, the restricting piece 9, the connecting band 10 and the moving mechanism 13 are provided, the range of the diameter of the mount 1 that can be adjusted can be expanded. Of course, without providing a plurality of dividing grooves 3 or the like in this manner, it is possible to cope with pipe rods K having a small diameter to a large diameter by appropriately changing the molding dimension of the tension band 2.

  In the above-described embodiment, the left and right ends of the restriction piece 9 are guided by the opposed end portion 4 constituted by the circumferential end portion 6, the spacer 7 and the guide piece 8. For example, the end 6 in the circumferential direction may be eliminated, and the left and right ends of the regulating piece 9 may be guided by the main body 11 of the connecting band 10, the spacer 7 and the guide piece 8.

  In the above embodiment, the end of the spacer 7 that receives the contact between the left and right sides 9a and 9b of the restriction piece 9 is inclined so as to correspond to the inclination angle of the left and right sides 9a and 9b of the restriction piece 9, 6 and the tip of the guide piece 8 are also inclined in the same manner as the tip of the spacer 7. However, the present invention is not limited to this, and in essence, a set of opposing ends as the restricting piece 9 enters and retracts into the dividing groove 3. The distance between the portions 4 only needs to be enlarged or reduced. For example, the spacer 7, the circumferential end 6 and the tip of the guide piece 8 are parallel to the axial direction (X direction). It may be made to become.

  In the above embodiment, the main body 11 of the connecting band 10 is configured to be along the outer peripheral side of the tension band 2, but the main body 11 may be configured to pass through the inner peripheral side of the tension band 2, In this case, the stand 17 or the slider 18 (and the slider 19) may be fixed to the outer peripheral surface side instead of the inner peripheral surface side of the main body 11.

  In the above embodiment, the slider 19 is provided as the moving mechanism 13 in addition to the slider 18. However, the slider 19 may not be provided. Moreover, in the said embodiment, although the slider 18 is provided between the two protrusion parts 15, the example of arrangement | positioning of the protrusion part 15 is not restricted to this, For example, when providing two sliders 18 and 19, these are provided. Even if the two projecting portions 15 are provided with an interval in the axial direction (X direction) only between the two sliders 18 and 19, the same function can be exhibited. If the interval 19 is narrowed to some extent, it is also possible to have one projecting portion 15 provided between these 18 and 19.

  In the above embodiment, the stand 17 is provided on the connecting band 10 and the slider 18 (and the slider 19) is provided on the restriction piece 9. Conversely, the stand 17 is provided on the restriction piece 9 and the slider 18 (and slider 19) is provided. You may make it provide in the connection band 10. FIG. In this case, the protrusion 15 may be provided so as to correspond to the slider 18 (slider 19).

  The installation direction of the mount 1 with respect to the pipe rod K may be determined in consideration of the ease of operation of the moving mechanism 13 (hexagonal portion 20). In the example shown in FIG. 1, the hexagonal portion 20 and the streamlined head S3 of the sensor S are oriented in the same direction in the mount 1 installed on the tube K, but the direction of the sensor S is the fluid in the tube K The sensor S may be provided in the direction opposite to that in FIG. That is, the mount 1 is preferably configured so that the orientation of the sensor S with respect to the mount 1 is variable (changeable by 180 degrees). Incidentally, reference numeral 21 in FIGS. 3 and 4 is a sensor mounting hole for mounting the sensor S to the mount 1, and is provided in the main body 5 of the tension band 2. The direction of the sensor S to be attached to this can be changed by 180 degrees. ing.

  Needless to say, the above modifications may be combined as appropriate.
