Description

  The present invention relates to a drainage basin that is suitably installed, for example, in a bent portion of a drainage pipe in a residential land.

  Usually, there are bent portions in the drainage pipes and the like in residential land, and there are cases where drainage drains are provided at such bent portions. The drainage basin provided in the bent portion has an inflow port and an outflow port, and a curved flow path from the inflow port to the outflow port is formed in the inside. For example, as an example of such a drain, a so-called 90-degree bent drain, that is, a drain with an inlet and an outlet opened in directions orthogonal to each other is known.

  By the way, the pipe bottom of the drainage pipe line needs to have a gradient that descends from the upstream side toward the downstream side. The bottom of the drainage basin is also provided with a gradient that descends from the inlet side toward the outlet side. For this reason, the inflow port and the outflow port cannot normally be used in reverse.

  The bent portion of the drainage pipe has a left bent portion that turns to the left in the traveling direction and a right bent portion that turns to the right in the moving direction. As described above, since the inlet and outlet cannot be used in reverse, conventionally, a drain for left is installed at the left turn, and a drain for right is installed at the right turn.

  However, if the left and right drainage drains are properly used depending on the direction of the bent part of the drainage pipe at the construction site, two types of drainage drains for the left and right must be manufactured and stored in advance. Don't be. Therefore, there is a problem that product inventory increases.

  Therefore, it has been proposed to use a drainage basin having no gradient at the tube bottom itself as a left and right drainage basin (see, for example, Patent Document 1). The left and right drainage basin is installed at a slight angle at the construction site. As a result, a gradient is secured at the bottom of the drainage basin. By using the left and right drainage basins, there is no need to use two types of drainage basins according to the direction of the bent portion, and the product inventory can be reduced.

Japanese Patent Laid-Open No. 11-21988

  However, with the above-mentioned drainage basin for both left and right, it is necessary to incline the drainage basin itself, but it is not always easy to install the drainage basin so as to have an appropriate gradient.

  This invention is made | formed in view of this point, The place made into the objective is to provide the drainage basin for both right and left easy to install.

  The drainage basin according to the present invention has a pipe section having a pipe bottom in which a connection port is formed at one end and an outflow port is formed at the other end, and a downward slope is provided from the connection port side toward the outflow port side. And a main body having a cylindrical portion extending upward from the pipe section, an inflow port is formed at one end, and a connection port is formed at the other end, and the connection port is rotated to the connection port of the pipe section. And a freely connected bent pipe.

  According to the drainage basin, since both connection ports are rotatably connected, the bent pipe can be further rotated with respect to the main body. The drainage basin can be used as a drainage basin for the left by rotating the bent pipe so that the outlet is located on the left side when the inlet is viewed from the front. Further, when the inflow port is viewed from the front, the bent pipe is rotated so that the outflow port is located on the right side, so that it can be used as a right drain. Therefore, the same drainage can be used as the drainage basin for the left and the right by appropriately rotating the bent pipe according to the direction of the bent portion of the drainage pipe. Therefore, it is not necessary to use two types of drainage basins separately, and the product inventory can be reduced. Moreover, since it is not necessary to incline the drainage tank itself, the installation is easy.

  The angle formed by the opening direction of the inlet of the bent pipe and the opening direction of the connection port may be 90 degrees. This makes it possible to obtain a drainage basin that is suitably used for a bent portion of a drainage pipe whose traveling direction changes by 90 degrees.

  The drainage pipe regulates a rotation range of the bent pipe with respect to the main body so that a downward slope is not formed from a connection port of the bent pipe toward the inlet with the rotation of the bent pipe with respect to the main body. A stopper may be provided. As a result, it is possible to reliably prevent the smooth flow of the waste water from being hindered or the drainage from flowing backward.

  The drainage basin may further include another bent pipe in which an inlet is formed at one end and a connection port is formed at the other end, and the connection port is rotatably connected to the inlet of the bent pipe. .

  As a result, the bent pipe is further rotated with respect to the main body, and the other bent pipe is rotated with respect to the bent pipe, so that the inlet of the other bent pipe (this inlet is drained by its own flow). The position and orientation of the entrance can be changed relatively freely. Therefore, the position adjustment between the inlet and the pipe connected to the inlet becomes easy.

  The angle formed by the opening direction of the inlet of the other bent pipe and the opening direction of the connection port may be 90 degrees. Accordingly, the rotation direction of the bent pipe and the rotation direction of the other bent pipe are orthogonal to each other, and the position and orientation of the drainage outlet (that is, the outlet of the other bent pipe) can be easily adjusted.

  As described above, according to the present invention, it is possible to provide a left and right drainage basin that can be easily installed.

<First Embodiment>
As shown in FIG. 1, the drainage basin 10 according to the present embodiment is installed at a bent portion of the drainage pipeline 5 in the residential land. The drainage basin 10 is connected to the inflow pipe 1 and the outflow pipe 2. The drainage flows in the order of the inflow pipe 1, the drainage trough 10, and the outflow pipe 2. The inflow pipe 1, the drainage trough 10, and the outflow pipe 2 constitute a part of the drainage pipe 5 embedded in the ground. In addition, the kind of waste_water | drain is not specifically limited, For example, dirty water may be sufficient and rain water may be sufficient.

  The drainage basin 10 is provided with a main body 20 and a bent pipe 30. The main body 20 and the bent pipe 30 are made of resin and assembled to each other.

  As shown in FIG. 2, the main body 20 is composed of a pipeline portion 21 extending in the horizontal direction and a cylindrical portion 22 extending upward from the pipeline portion 21. The pipe line part 21 and the cylinder part 22 are integrally formed. However, the pipe line part 21 and the cylinder part 22 may be formed separately and assembled to each other. A connection port 23 is formed at one end of the conduit portion 21 and an outflow port 24 is formed at the other end. A pipe bottom 25 having a gradient that descends from the connection port 23 side toward the outlet port 24 side is formed inside the pipe line portion 21. Although not shown, an inspection cylinder is fitted into the cylinder portion 22 from above. Through this inspection cylinder, it is possible to inspect 10 drains from the ground surface. The outflow port 24 is a receiving port, and the outflow pipe 2 is fitted into the outflow port 24 (see FIG. 1). However, the outflow port 24 is not limited to the receiving port, and may be an outlet.

  As shown in FIG. 1, an inflow port 31 is formed at one end of the bent tube 30, and a connection port 32 is formed at the other end. The bent tube 30 is bent 90 degrees. The symbol R represents the bending direction of the bent tube 30. The angle formed by the opening direction of the inflow port 31 and the opening direction of the connection port 32 is 90 degrees. However, the angle is not necessarily limited to 90 degrees. The inflow port 31 is a receiving port, and the inflow pipe 1 is fitted into the inflow port 31. However, the inflow port 31 is not limited to the receiving port, and may be a difference port. The connection port 32 of the bent pipe 30 is connected to the connection port 23 of the main body 20 so as to be rotatable.

  Next, the structure of the connection port 23 and the connection port 32 will be described. However, the structure of the connection port 23 and the connection port 32 is not limited to the structure described below as long as they are rotatable with respect to each other.

  FIG. 3 is a longitudinal sectional view when the connection port 23 and the connection port 32 are cut along the vertical direction. However, the connection port 32 is a vertical cross-sectional view in a state where the bent pipe 30 is vertically raised (in other words, the inflow port 31 is opened upward). The connecting port 23 of the main body 20 is a receiving port. A concave portion 23 a extending in a circumferential shape is formed on the inner peripheral surface of the connection port 23. The connection port 32 of the bent pipe 30 is an insertion port. On the outer peripheral surface of the connection port 32, a convex portion 32a extending in a circumferential shape and a concave portion 32b extending in a circumferential shape are formed. The concave portion 32b is located on the tip side of the convex portion 32a.

  FIG. 4 is a partial cross-sectional view showing a state in which the connection port 23 and the connection port 32 are connected to each other. As shown in FIG. 4, when the connection port 32 is inserted into the connection port 23, the convex portion 32 a of the connection port 32 is fitted into the concave portion 23 a of the connection port 23. Since both the convex portion 32a and the concave portion 23a extend circumferentially, the convex portion 32a cannot be easily moved in the axial direction, but can be easily moved in the circumferential direction. Therefore, the connection port 32 can rotate with respect to the connection port 23.

  A seal 40 such as an O-ring is fitted in the recess 32b. The seal 40 closes the gap between the connection port 23 and the connection port 32.

  The angle range in which the connection port 32 can rotate with respect to the connection port 23 is not particularly limited, but is set to 180 degrees in the present embodiment. When the connection port 23 is viewed from the front (in other words, when the connection port 23 is viewed from the right side of FIG. 3), the connection port 32 is configured to be rotatable by 90 degrees left and right. When the drainage basin 10 is installed in the left-turned part of the drainage pipe 5, the connection port 32 may be rotated 90 degrees to the left. When the drainage basin 10 is installed in the right-handed part of the drainage pipe 5 The connection port 32 may be rotated 90 degrees to the right. In the present embodiment, the connection port 23 and the connection port 32 are arranged so that the connection port 32 stops at a predetermined position, that is, a position rotated 90 degrees to the left or right when the bend pipe 30 is rotated left or right. Stoppers 41 and 42 are provided.

  The stoppers 41 and 42 restrict the rotation range of the bent tube 30 so that a downward gradient is not formed from the connection port 32 toward the inlet 31 as the bent tube 30 rotates. In other words, the angle range in which the bent tube 30 can be rotated is restricted to the above-described 180 degree range, so that excessive rotation of the bent tube 30 is prevented, and the bent tube 30 is always kept in an appropriate posture. Thereby, the smooth distribution of the drainage in the bent pipe 30 is ensured, and the backflow of the drainage is prevented.

  The stoppers 41 are provided on the left side and the right side of the connection port 23, respectively. The upper side of the stopper 41 is an abutting surface 41 a that abuts against the stopper 42. The stopper 42 is provided on the outer peripheral surface of the connection port 32 and protrudes outward in the radial direction. The stopper 42 is provided above the connection port 32. In other words, the stopper 42 protrudes in the opening direction of the inflow port 31 (upward direction in FIG. 3). The stopper 42 may be separate from the connection port 32 or may be integrated as in the present embodiment. The stopper 42 is disposed on the back side (right side in FIG. 3) from the convex portion 32a.

  When the bent tube 30 is rotated to the left, the stopper 42 of the connection port 32 contacts the contact surface 41a of the left stopper 41 of the connection port 23, and the rotation of the bent tube 30 is restricted. As a result, the drainage basin 10 can be used as a drainage basin for the left suitable for the left bent portion of the drainage pipe 5 (see FIG. 1). On the other hand, when the bent tube 30 is rotated to the right side, the stopper 42 of the connection port 32 contacts the contact surface 41a of the right side stopper 41 of the connection port 23, and the rotation of the bent tube 30 is restricted. As a result, the drainage basin 10 can be used as a drainage basin for the right suitable for the right-turn portion of the drainage pipe 5 (see FIG. 5). The stoppers 41 and 42 are also used as positioning means for the bent tube 30.

  As described above, the drainage basin 10 can be used as a drainage basin for left and right by rotating the bent pipe 30 left and right with respect to the main body 20. Therefore, it is not necessary to use two types of drainage basins separately, and the product inventory can be reduced. Further, the pipe bottom 25 of the main body 20 is provided with an appropriate gradient in advance, so that it is not necessary to incline the drainage basin 10 itself. Therefore, it is easy to install the drainage basin 10 so as to have an appropriate gradient. According to the present embodiment, it is possible to obtain a left and right drainage basin 10 that is easy to install.

Second Embodiment
As shown in FIGS. 6 to 8, the drainage basin 10B according to the second embodiment is obtained by rotatably connecting another bent pipe 50 to the bent pipe 30 of the drainage basin 10 according to the first embodiment. The same reference numerals are given to the same parts as those in the first embodiment, and the description thereof is omitted.

  As shown in FIG. 7, an inflow port 51 is formed at one end of the other bent pipe 50, and a connection port 52 is formed at the other end. Similar to the bent tube 30, the bent tube 50 is bent 90 degrees. The angle formed by the opening direction of the inflow port 51 and the opening direction of the connection port 52 is 90 degrees. However, the angle is not necessarily limited to 90 degrees. The inflow port 51 is a receiving port, and an inflow pipe (not shown) is connected to the inflow port 51. The structure of the inflow port 51 is not limited at all, and may be, for example, a receiving port (adhesion receiving port) that is connected to the inflow pipe in a watertight manner by being bonded, and is watertight to the inflow pipe through a rubber ring. It may be a receptacle (rubber ring receptacle) of the type connected to In addition, the inflow port 51 is not limited to the receiving port, and may be a difference port.

  In the present embodiment, the inlet 31 of the bent tube 30 is a connection port connected to the connection port 52 of the bent tube 50. The connection port 52 is rotatably connected to the inlet 31 of the bent pipe 30. As long as they are rotatable with respect to each other, the structures of the inflow port 31 and the connection port 52 are not limited at all. For example, the same structure as the connection port 23 and the connection port 32 of the first embodiment may be used.

  The material of the bent pipe 50 is not limited at all, and may be made of resin like the bent pipe 30, for example.

  According to the drainage basin 10B according to the present embodiment, the bent pipe 30 is appropriately rotated with respect to the main body 20, and further the bent pipe 50 is appropriately rotated with respect to the bent pipe 30, thereby being used in various modes. It becomes possible. The drainage basin 10B can be installed at various bent portions of the drainage pipe. Further, the positional relationship between the inflow port 51 and the outflow port 24 can be appropriately adjusted by appropriately rotating the bent tube 30 and the bent tube 50. Therefore, the position can be finely adjusted in connection with the inflow pipe and the outflow pipe.

  Moreover, it is also possible to make the height position of the inflow port 51 and the height position of the outflow port 24 different (refer FIG. 7). The drainage basin 10B can be used not only as a drainage basin for the left or right, but also in a place where the height position of the inflow pipe is different from the height position of the outflow pipe.

  For example, as shown in FIGS. 9 and 10, the bent pipe 30 is further rotated 90 degrees with respect to the main body 20, and the bent pipe 50 is rotated by a predetermined angle with respect to the bent pipe 30, whereby the height position of the inflow port 51 is increased. Can be adjusted appropriately. According to this embodiment, position adjustment of the inflow port 51 and the inflow pipe 1 is easy. In the example shown in FIGS. 9 and 10, the inflow pipe 1 is formed by a plurality of pipe members.

  Further, for example, if the bent pipe 50 is rotated 45 degrees to the left or right from the state shown in FIG. 7, the drainage drain 10B can be installed at a portion where the traveling direction changes by 45 degrees in the drain pipe. Since the rotation angle of the bent pipe 50 can be set arbitrarily, the drainage 10B can be installed not only in the part where the traveling direction changes by 45 degrees but also in other parts. When the bent pipe 50 is rotated 90 degrees to the left from the state shown in FIG. 7, the drainage basin 10B can be used as a drainage basin for the left side. On the contrary, when the bent pipe 50 is rotated 90 degrees to the right from the state shown in FIG. 7, the drainage basin 10B can be used as a drainage basin for the right side.

<Other embodiments>
In the second embodiment, the main body 20 and the two bent pipes 30 and 50 are combined. However, the main body 20 and the bent pipe 30 may be integrated into one body, or the bent pipe 30 may be fixed to the main body 20 so as not to rotate. In this case, the whole of the main body 20 and the bent pipe 30 which cannot rotate with respect to each other can be regarded as one main body. Even in this case, although the height positions of the inlet 51 and the outlet 24 are different, as long as the bent pipe 50 is rotatable with respect to the main body (that is, the combination of the main body 20 and the bent pipe 30). Can be used as a left and right drain.
