[0001] The present invention relates to a water level gauge base material for producing a water level gauge to be installed in a farm field, a method for producing a water level gauge main body using the water level gauge base material, and a method for producing a water level gauge using the water level gauge main body. [Background technology]
[0002] Conventionally, there have been water level gauges for monitoring the water level in rice paddies. For example, a marker water level gauge 11 shown in Patent Document 1 includes a main body 12 and a base 13 that supports the main body 12 (see FIG. 12). The main body 12 is cone-shaped and is divided in the height direction, with main body surface regions 12a, 12a that are different in color from each other. The base 13 is made of a rubber plate and serves as a weight for the marker water level gauge 11. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-156778 Summary of the Invention [Problem to be solved by the invention]
[0004] However, with the conventional marker water level gauge 11, when transporting a large number of marker water level gauges 11, 11 at once to install them in each rice paddy, each marker water level gauge was heavy enough to act as a weight, and due to its shape it was bulky, making it difficult to transport.
[0005] The present invention has been made to solve the above-mentioned drawbacks of the conventional technology, and its object is to provide a water level gauge base material that can be easily transported in large numbers, a method for manufacturing a water level gauge body using the water level gauge base material, and a method for manufacturing a water level gauge. [Means for solving the problem]
[0006] In order to achieve the above-mentioned object, the water level gauge base material, the method for manufacturing the water level gauge body, and the method for manufacturing the water level gauge according to the present invention are configured as follows: The water level gauge base according to claim 1 is a flat-shaped water level gauge base for manufacturing a water level gauge to be installed in a field. This water level gauge base includes a base portion to be placed on the soil in the field, a stake portion to be inserted into the soil to fix the base portion to the soil, and a water level measuring portion whose tip protrudes above the water surface in the field to measure the water level in the field. Here, the stake portion extends from the base, and the stake portion and the base are bendable at their joints. The water level measuring portion extends from the base, and the water level measuring portion and the base are bendable at their joints. Thus, the water level gauge main body of the water level gauge can be formed by bending the stake portion toward the bottom surface of the base at their joints and bending the water level measuring portion toward the top surface of the base at their joints.
[0007] According to this water level gauge base material, the water level gauge base material includes a base portion that is placed in the soil in the field, a stake portion that is inserted into the soil, and a water level measuring portion whose tip protrudes above the water surface in the field. Here, the water level gauge base material is flat, and the water level gauge main body can be easily formed by bending the stake portion toward the underside of the base at their joints, and bending the water level measuring portion toward the upper side of the base at their joints. Therefore, by stacking the water level gauge base materials in their flat, unfolded state rather than in the state of the water level gauge main body, it becomes easy to transport a large number of these base materials together without increasing their bulk.
[0008] The water level gauge base according to the invention described in claim 2 is the water level gauge base according to claim 1, wherein the pile portion and the base portion are adjacent to each other across a slit extending in the extension direction of the pile portion.
[0009] The water level gauge base material according to the invention described in claim 3 is the water level gauge base material described in claim 1, wherein the water level measuring portion and the base portion are adjacent to each other across a slit extending in the extension direction of the water level measuring portion.
[0010] The water level gauge base material according to claim 4 is the water level gauge base material according to claim 1, wherein the pile portion and the base portion are adjacent to each other across a first slit extending in the extension direction of the pile portion, and the water level measuring portion and the base portion are adjacent to each other across a second slit extending in the extension direction of the water level measuring portion.
[0011] The water level gauge base according to claim 5 is the water level gauge base according to claim 4, wherein the base comprises a main base extending in one direction, a first base extending from one side of the main base in the one direction in a direction intersecting the one direction, and a second base extending from the other side of the main base in the one direction in a direction intersecting the one direction. The pile extends from a side of the first base facing the other side toward the other side, and the first slit is formed between the pile and the main base. The water level measuring unit extends from a side of the second base facing the one side toward the one side, and the second slit is formed between the water level measuring unit and the main base.
[0012] The water level gauge base material according to the invention described in claim 6 is the water level gauge base material described in any one of claims 1 to 5, wherein a hole, notch or groove is formed in the connecting portion between the pile portion and the base portion to facilitate bending. And a hole, notch or groove is formed in the connecting portion between the water level measuring portion and the base portion to facilitate bending.
[0013] The water level gauge base material according to the invention described in claim 7 is the water level gauge base material described in any one of claims 1 to 5, in which a plurality of colored parts made of different colors are arranged in the direction in which the water level measuring part extends. This makes it possible to easily measure the water level in the field based on the color of the water level measuring part exposed above the water surface.
[0014] The water level gauge base material according to the invention described in claim 8 is the water level gauge base material described in any one of claims 1 to 5, wherein the base has an attachment part for attaching a stake member to be inserted into the soil. By attaching a stake member to the base, the base, and therefore the water level gauge body, can be more stably fixed to the soil.
[0015] A method for manufacturing a water level gauge body according to the invention described in claim 9 uses the water level gauge base material described in any one of claims 1 to 5. In this method for manufacturing a water level gauge body, the stake portion is bent downward from the base portion at the joint portion thereof in the water level gauge base material, and the water level measuring portion is bent upward from the base portion at the joint portion thereof to form the water level gauge body.
[0016] Furthermore, the method for manufacturing a water level gauge body according to the invention recited in claim 10 is the method for manufacturing a water level gauge body recited in claim 9, wherein when bending the stake portion relative to the base portion toward the underside of the base at their joint, the stake portion is bent so as to face diagonally downward relative to the base portion. As a result, when the water level gauge body tries to come straight out of the soil or when the water level gauge body tries to tip over sideways, the soil acts on the stake portion, making it less likely for the water level gauge body to come out or tip over.
[0017] In addition, the method for manufacturing a water level meter according to the invention described in claim 11 comprises assembling a float that floats on water to the water level measuring section of a water level meter body manufactured by the method for manufacturing a water level meter body described in claim 9 so that the float can slide up and down in accordance with fluctuations in the water level in the field. [Effects of the Invention]
[0018] According to the water level gauge base material of the present invention, by stacking the base materials in the form of flat plates, it becomes possible to easily transport a large number of the base materials together without increasing the bulk.
[0019] Furthermore, according to the method for manufacturing a water level gauge body and a water level gauge of the present invention, a large number of water level gauge base materials can be transported together, and the water level gauge body or water level gauge can be formed at the destination using the water level gauge base materials.

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0022] 1 to 7 show one embodiment of the present invention. In the drawings, reference numeral 1 denotes a farm field. Reference numeral 2 denotes a water level gauge to be installed in the farm field 1. Reference numeral 3 denotes a flat water level gauge base material for manufacturing the water level gauge 2.
[0023] The water level gauge 2 comprises a water level gauge main body 2a. The water level gauge base 3 comprises a base 3a placed on the soil 1a in the farm field 1, a stake 3b inserted into the soil 1a to fix the base 3a to the soil 1a, and a water level measuring part 3c whose tip protrudes from the water surface 1b in the farm field 1 to measure the water level in the farm field 1. The stake 3b extends from the base 3a, and the stake 3b and the base 3a are bendable at a joint 3d between them. The water level measuring part 3c extends from the base 3a, and the water level measuring part 3c and the base 3a are bendable at a joint 3e between them. Therefore, the pile portion 3b is bent from the base portion 3a toward the underside of the base 3a at their connecting portion 3d, and the water level measuring portion 3c is bent from the base portion 3a toward the upper side of the base 3a at their connecting portion 3e, thereby making it possible to form the water level meter main body 2a.
[0024] In detail, in the state of the water level gauge base material 3, the pile portion 3b and the base portion 3a are adjacent to each other with a first slit 3f, which is a slit extending in the extension direction of the pile portion 3b, between them. Similarly, in the state of the water level gauge base material 3, the water level measuring portion 3c and the base portion 3a are adjacent to each other with a second slit 3g, which is a slit extending in the extension direction of the water level measuring portion 3c, between them. In the illustrated embodiment, the water level gauge base material 3 has a rectangular outer shape excluding the tip side of the water level measuring portion 3c, and the tip side of the water level measuring portion 3c is formed to protrude from the rectangular shape.
[0025] More specifically, the base 3a includes a main base 3i extending in one direction 3h, a first base 3j extending from one side 3x of the main base 3i in the direction 3h in a direction intersecting the direction 3h (in the illustrated embodiment, a direction perpendicular to the direction), and a second base 3k extending from the other side 3y of the main base 3i in the direction intersecting the direction 3h (in the illustrated embodiment, a direction perpendicular to the direction). In the state of the water level gauge base material 3, the stake 3b extends from the side of the first base 3j facing the other side 3y toward the other side 3y, and the first slit 3f is formed between the stake 3b and the main base 3i. Then, in the state of the water level meter base material 3, the water level measuring portion 3c extends from the side facing the one side 3x of the second base portion 3k toward the one side 3x, and the second slit 3g is formed between the water level measuring portion 3c and the main base portion 3i.
[0026] The method for manufacturing the water level gauge main body 2a using this water level gauge base material 3 involves bending the stake portion 3b from the base portion 3a at their joint portion 3d toward the underside of the base 3a, and bending the water level measuring portion 3c from the base portion 3a at their joint portion 3e toward the upper side of the base 3a to form the water level gauge main body 2a. When bending the stake portion 3b from the base portion 3a at their joint portion 3d toward the underside of the base 3a, the stake portion 3b is bent so that it faces diagonally downward relative to the base 3a.
[0027] In addition, the manufacturing method of the water level gauge 2 is to attach a float 4 that floats on water to the water level measuring part 3c of the water level gauge main body 2a manufactured by the manufacturing method of the water level gauge main body 2a so that it can slide up and down in accordance with changes in the water level in the field 1.
[0028] Specifically, the water level gauge base material 3 is made of a metal plate such as a steel plate or an aluminum alloy plate, another plate, or a composite plate made by stacking multiple plates of different types. Two main bases 3i are provided in the base portion 3a of this water level gauge base material 3, and these main bases 3i, 3i are arranged in parallel. Two first bases 3j are provided, and each first base 3j extends in a direction away from the one side 3x of the respective main base 3i. A second base 3k is provided on the other side 3y of the main base 3i so as to connect both main bases 3i, 3i.
[0029] Two piles 3b are provided, each extending from the corresponding first base 3j parallel to the main base 3i. One water level measuring unit 3c is provided, and this water level measuring unit 3c extends from the second base 3k between the two main bases 3i, 3i, parallel to the main base 3i, and further extends beyond the main bases 3i, 3i.
[0030] Furthermore, a hole, notch, or groove (hole 3m (more specifically, a long hole) in the illustrated embodiment) is formed in connecting portion 3d between pile portion 3b and first base portion 3j (base portion 3a) to facilitate bending. Similarly, a hole, notch, or groove (hole 3n (more specifically, a long hole) in the illustrated embodiment) is formed in connecting portion 3e between water level measuring portion 3c and second base portion 3k (base portion 3a) to facilitate bending.
[0031] The base 3a also has mounting portions 3p for mounting stake members 5 to be inserted into the soil 1a, and in the case of the water level gauge main body 2a (water level gauge 2), the stake members 5 are mounted to these mounting portions 3p as needed (see FIG. 7). In the illustrated embodiment, these mounting portions 3p comprise mounting holes 3q into which the stake members 5 are inserted. More specifically, two mounting holes 3q are provided. The stake members 5 are formed in a U-shape, and each leg 5a is inserted into the corresponding mounting hole 3q.
[0032] The float 4 is formed in a disk shape with a through-hole 4a drilled in its center. The float 4 is assembled to the water level gauge main body 2a with the water level measuring unit 3c fitted into the through-hole 4a. A retaining member 6 is attached to the upper end of the water level measuring unit 3c to prevent the float 4 from slipping out. The retaining member 6 is made up of a male screw member 6a and a nut 6b. The male screw member 6a is passed through a hole 3r drilled in the upper end of the water level measuring unit 3c, and the nut 6b is screwed into the male screw member 6a, thereby attaching the retaining member 6 (male screw member 6a and nut 6b) to the water level measuring unit 3c.
[0033] Next, we will explain the effects of the method for manufacturing the water level gauge base material 3 and water level gauge main body 2a, which are configured as described above, and the method for manufacturing the water level gauge 2. The water level gauge base material 3 comprises a base 3a that is placed on the soil 1a in the farm field 1, a stake 3b that is inserted into the soil 1a, and a water level measuring part 3c whose tip protrudes from the water surface 1b in the farm field 1. Here, the water level gauge base material 3 is flat, and the water level gauge main body 2a can be easily formed by bending the stake 3b from the base 3a at their joint 3d toward the underside of the base 3a, and bending the water level measuring part 3c from the base 3a at their joint 3e toward the upper side of the base 3a. Therefore, by stacking the base materials 3, 3 in the state of the water level meter base material 3 before folding, that is, in a flat plate-like state, rather than in the state of the water level meter main body 2a, it becomes easy to transport a large number of the base materials 3, 3 together to the field 1 without them becoming bulky.
[0034] That is, with this water level gauge base material 3, by stacking the base materials 3, 3 in the form of flat plates, it becomes easy to transport a large number of these base materials 3, 3 together to the farm field 1 without taking up too much space, and at the farm field 1 (destination), the water level gauge main body 2a can be easily formed from the water level gauge base material 3 by folding it. Also, the water level gauge 2 can be formed by combining the water level gauge main body 2a with a float 4.
[0035] Furthermore, since the water level gauge base material 3 (water level gauge main body 2a) is plate-shaped and has a stake portion 3b that is inserted into the soil 1a, it is possible to reduce the weight of this water level gauge base material 3 (water level gauge main body 2a).
[0036] Furthermore, in the water level gauge base material 3, the pile portion 3b and the base portion 3a are adjacent to each other across the first slit 3f, and the water level measuring portion 3c and the base portion 3a are adjacent to each other across the second slit 3g, resulting in a cohesive shape (in the illustrated embodiment, the water level measuring portion 3c has a rectangular outer shape except for the tip side), which results in good yield when cutting the water level gauge base material 3 from plate material.
[0037] The base 3a also has an attachment portion 3p for attaching a stake member 5 to be inserted into the soil 1a. By attaching the stake member 5 to the base 3a, the base 3a, and therefore the water level gauge main body 2a, are more stably fixed to the soil 1a.
[0038] Furthermore, according to the method for manufacturing the water level gauge main body 2a and the method for manufacturing the water level gauge 2, a large number of water level gauge base materials 3 can be transported together to the field 1, and the water level gauge main body 2a or the water level gauge 2 can be formed in the field 1 (destination) using the water level gauge base materials 3.
[0039] Furthermore, when bending the pile portion 3b from the base 3a at their connecting portion 3d toward the underside of the base 3a, if the pile portion 3b is bent so that it faces diagonally downward relative to the base 3a, when the water level meter main body 2a (more specifically, the pile portion 3b) tries to come straight out of the soil 1a or when the water level meter main body 2a tries to tip over sideways, the pile portion 3b will be subjected to the resistance of the soil 1a, making it difficult for the water level meter main body 2a to come out or tip over.
[0040] Furthermore, the stake portion 3b and the water level measuring portion 3c are located on opposite sides, and the water level meter main body 2a (water level meter 2) is well balanced when installed in the field 1.
[0041] The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the water level indicator 2 includes the water level indicator main body 2a and the float 4, but the water level indicator main body 2a may serve as the water level indicator 2 without including the float 4.
[0042] Furthermore, the base 3a has an attachment portion 3p for attaching the stake member 5, but this attachment portion 3p may be omitted.
[0043] 8, the water level measuring unit 3c may be provided with a plurality of colored portions 3s, 3s of different colors arranged in the direction of extension of the water level measuring unit 3c. The color of the colored portions 3s (i.e., the color of the colored portions 3s) of the water level measuring unit 3c exposed above the water surface 1b makes it possible to easily measure the water level in the field 1. That is, when a float 4 is used, the color of the colored portion 3s located at the top of the float 4 can be used to determine the water level in the field 1. When a float 4 is not used, the color of the colored portion 3s located at the water surface 1b can be used to determine the water level. Here, the colors of the colored portions 3s may be, for example, red, yellow, and blue from bottom to top, with red indicating low water, yellow indicating water is almost low, and blue indicating sufficient water.
[0044] Furthermore, the water level measuring unit 3c may be provided with a scale or the like that indicates the water level in the farm field 1.
[0045] Furthermore, in the water level gauge base material 3, the second base 3k may extend from one side 3x of the direction 3h in which the main base 3i extends in a direction intersecting the direction 3h (in the illustrated embodiment, a direction perpendicular to the direction 3h) instead of extending from the other side 3y of the direction 3h in which the main base 3i extends in a direction intersecting the direction 3h (see FIG. 9). In this case, the water level measuring unit 3c extends from the side of the second base 3k facing the other side 3y toward the other side 3y, and a second slit 3g is formed between the water level measuring unit 3c and the main base 3i.
[0046] 10, the water level gauge base material 3 may be composed of a rectangular base 3a, stakes 3b extending from one side of the base (in the illustrated embodiment, stakes 3b, 3b extending from both ends of the side), and a water level measuring part 3c extending from the other side opposite the one side (in the illustrated embodiment, the water level measuring part 3c extending from the center of the other side). Fig. 11 shows a water level gauge main body 2a formed using this water level gauge base material 3.
[0047] Furthermore, a hole 3m is formed in the connecting portion 3d between the pile portion 3b and the base portion 3a to facilitate bending, but this hole 3m may be omitted. Similarly, a hole 3n is formed in the connecting portion 3e between the water level measuring portion 3c and the base portion 3a to facilitate bending, but this hole 3n may be omitted.
