Description

  The present invention relates to a detachable water supply apparatus including a pipe and a fluid machine that is detachable from the pipe.

  Conventionally, for example, in the field of sewage treatment, a pipe installed in a water tank and a fluid machine (for example, an underwater mixer or an underwater pump) attached outside the inlet or outlet of the pipe are provided. A watering device is known. When the fluid machine is attached to the inlet of the pipe, the water in the water tank is introduced into the pipe by operating the fluid machine in water. And the water introduce | transduced in piping is returned in a water tank through the said piping, or is discharged | emitted out of a water tank. On the other hand, when the fluid machine is attached to the outlet of the pipe, when the fluid machine operates in water, water in the pipe is sucked by the fluid machine and supplied from the pipe into the water tank.

  By the way, in order to facilitate installation and maintenance of the fluid machine, the fluid machine is often configured to be detachable from the pipe. For example, in the devices disclosed in the following Patent Documents 1 to 3, a guide rod extending in the vertical direction is provided in the water tank, and the fluid machine is suspended along the guide rod to the vicinity of the inlet of the pipe, thereby fluid to the pipe. The machine can be installed automatically. In the above apparatus, during the maintenance, the fluid machine is lifted along the guide rod to be removed from the pipe and carried out of the water tank.

  Here, a conventional detachable water supply device will be described with reference to FIG. The water feeding device includes a pipe 120 installed in a water tank and an underwater mixer 100 that is detachable from the pipe 120. A guide rod 110 extending in the vertical direction is attached to the upper portion of the pipe 120. The underwater mixer 100 includes an underwater motor 101, an impeller 102 connected to a rotation shaft of the underwater motor 101, and an impeller casing 103 that covers the periphery of the impeller 102. In addition, the underwater mixer 100 is provided with a support plate 104 and a roller 105 that is rotatably supported on the front end side of the support plate 104. The roller 105 is engaged with the guide rod 110 and guides the vertical movement of the underwater mixer 100 along the guide rod 110.

  In the detachable water feeding device, when the underwater mixer 100 is suspended to a predetermined position along the guide rod 110, the impeller casing 103 of the underwater mixer 100 reaches the position of the opening end of the pipe 120. As a result, the impeller casing 103 and the open end of the pipe 120 are continuous, and the underwater mixer 100 is attached to the pipe 120.

FIG. 8 shows another conventional detachable water supply device. The water feeding device includes a pipe 120 fixed in the water tank and a submersible pump 109 that is detachable from the pipe 120. The submersible pump 109 includes a submersible motor 107, an impeller 108 connected to the rotation shaft of the submersible motor 101, and a casing 106 that covers the entire submersible motor 101 and the impeller 108. Also in this water feeding device, the support plate 104 is fixed to the submersible pump 109, and the roller 105 that engages with the guide rod 110 is attached to the support plate 104. When the submersible pump 109 is suspended along the guide rod 110 to a predetermined position, the casing 106 of the submersible pump 109 and the open end of the pipe 120 are continuous, and the submersible pump 109 is attached to the pipe 120.

  However, the conventional detachable water feeding device has a problem that the installation area (plan view area) is large. That is, the conventional detachable water feeding device raises and lowers the submersible mixer 100 and the submersible pump 109 (hereinafter referred to as the submerged mixer 100) while maintaining the posture when the pipe 120 is mounted. Therefore, at least an area obtained by adding the installation area of the underwater mixer 100 itself and the installation area of the pipe 120 is necessary as the installation area of the apparatus.

  In addition, it is necessary to provide the underwater mixer 100 with an impeller casing 103 that covers the impeller 102. Further, the casing 106 that covers the entire submersible motor 101 and the impeller 108 is required for the submersible pump 109. Therefore, the size or weight of the underwater mixer 100 is increased by the amount of the casings 103 and 106, and it takes time and effort to attach and detach the underwater mixer 100 and the like.

  Furthermore, a lid 130 having an opening 131 may be provided in the water tank, such as a manhole pump station. However, in the conventional detachable water feeding device, in order to carry the underwater mixer 100 or the like into or out of the water tank, the opening 131 having a length A2 of the lateral length L2 or more of the underwater mixer 100 or the like is required. Met. That is, it is necessary to form a relatively large opening 131 in the lid 130.

  This invention is made | formed in view of this point, and one of the objectives is to make small opening of the cover of the installation water tank of a detachable water supply apparatus. Another object of the present invention is to reduce the installation area of the detachable water feeding device. Another object of the present invention is to reduce the size or weight of a fluid machine in a detachable water feeding device.

A detachable water supply device according to the present invention is installed in a water tank, and has a pipe having an open end opened in the water tank, and is detachably provided at the open end of the pipe, and is immersed in water in the water tank. A fluid machine that transports water through the pipe in a state where the fluid machine is installed, a guide rod that is installed in the water tank and extends substantially in the vertical direction, and is fixed to the fluid machine and engages with the guide rod. A detachable water supply device comprising a guide member for guiding up and down, wherein the fluid machine has an impeller, the axial direction of the impeller when the fluid machine is guided, and the fluid machine Are different from the axial direction of the impeller when mounted on the pipe.

  In the detachable water feeding device, the posture of the fluid machine is different between when being guided along the guide rod and when being attached to the pipe. That is, in the detachable water feeding device, the posture of the fluid machine is changed when it is attached to the pipe. Therefore, by adjusting the posture at the time of guiding the fluid machine, the planar view area of the fluid machine at the time of guiding can be made smaller than that at the time of wearing. When loading a fluid machine through the opening of the lid of the aquarium, it is possible to carry in the fluid machine through a smaller opening than before by adjusting the posture so that the area in plan view when loading is smaller than when installed. It becomes. Therefore, the required area of the lid opening can be reduced. In addition, the installation area of the entire apparatus can be reduced by adjusting the posture when the fluid machine is mounted.

Furthermore, in the detachable water supply device according to the present invention, when the fluid machine is mounted on the pipe, a part of the fluid machine is accommodated in the pipe from the open end of the pipe.

  Thus, a part of the fluid machine enters the inside of the pipe at the time of mounting. Therefore, in plan view, a part of the fluid machine and the piping overlap. Therefore, the planar view area of the entire apparatus is smaller than the sum of the planar view area of the fluid machine itself and the planar view area of the pipe itself. Therefore, the installation area of the whole apparatus is reduced.

  It is preferable that an impeller casing is provided at an opening end of the pipe, and the impeller is accommodated in the impeller casing when the fluid machine is mounted on the pipe.

  The impeller casing may be formed integrally with the pipe, may be formed separately from the pipe, and may be fixed to the pipe.

  This eliminates the need for an impeller casing in the fluid machine. Therefore, the fluid machine can be reduced in size and weight as much as there is no impeller casing.

The fluid machine includes a submersible motor having a rotating shaft connected to the impeller, and a casing that covers the impeller and a part of the submersible motor on the impeller side, and the fluid machine is connected to the pipe. When mounted, the casing and the pipe may be continuous, and the remaining portion of the submersible motor may be accommodated in the pipe.

  Thereby, a part of the submersible motor (a part on the side opposite to the impeller) is covered with the pipe. Therefore, it is not necessary to provide the fluid machine with a casing that covers the entire submersible motor. Therefore, the casing can be partially omitted, so that the fluid machine can be reduced in size and weight.

  It is preferable that a planar view area of the fluid machine and the pipe as a whole when the fluid machine is attached to the pipe is smaller than an area obtained by adding the planar views of the fluid machine and the pipe.

  As a result, the installation area of the detachable water feeder can be reduced.

  It is preferable that a part of the guide rod is bent, and the guide member includes a pinching member for pinching the guide rod.

  As a result, the fluid machine changes its posture along the curved shape of the guide rod. Therefore, the posture of the fluid machine can be arbitrarily changed by appropriately adjusting the curved shape of the guide rod. The posture change of the fluid machine can be realized with a simple configuration. The guide bar may be curved or bent.

Another detachable water supply device according to the present invention is installed in a water tank, and has a pipe having an open end opened in the water tank, and is detachably provided at the open end of the pipe. A fluid machine that transports water through the pipe in an immersed state, a guide rod that is installed in the water tank and extends in a substantially vertical direction, and is fixed to the fluid machine and engages with the guide rod, thereby the fluid. A detachable water supply device comprising a guide member for guiding the raising and lowering of the machine, wherein the fluid machine has an impeller, and the axial direction of the impeller when the fluid machine is guided, and The axial direction of the impeller when the fluid machine is attached to the pipe is different from each other, and the planar view area of the fluid machine and the pipe as a whole when the fluid machine is attached to the pipe is The fluid machine and the piping It is smaller than the area of the sum of the plan view area of, respectively.
  Another detachable water supply device according to the present invention is installed in a water tank, and has a pipe having an open end opened in the water tank, and is detachably provided at the open end of the pipe. A fluid machine that transports water through the pipe in an immersed state, a guide rod that is installed in the water tank and extends in a substantially vertical direction, and is fixed to the fluid machine and engages with the guide rod, thereby the fluid. A detachable water supply device comprising a guide member for guiding the raising and lowering of the machine, wherein the fluid machine has an impeller, and the axial direction of the impeller when the fluid machine is guided, and The axial direction of the impeller when a fluid machine is mounted on the pipe is different from each other, a part of the guide rod is bent, and the guide member is a pinch that holds the guide rod. A member is provided.

  As described above, according to the present invention, since the posture of the fluid machine is different before and after being attached to the pipe, the fluid machine is carried into the water tank in such a posture that the area in plan view is reduced. It is possible to reduce the opening of the lid. Further, if the posture of the fluid machine is changed at the time of mounting and a part of the fluid machine is accommodated in the pipe, the installation area of the entire apparatus can be reduced. Further, if a part or all of the casing for the fluid machine is provided on the piping side, the fluid machine can be reduced in size and weight by the amount that part or all of the casing becomes unnecessary.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1-3, the detachable water feeder which concerns on embodiment is equipped with the underwater mixer 10 and the piping 20, and is installed in the water tank. A lid 30 is provided above the water tank, and an opening 31 that is used to carry in and out the underwater mixer 10 is formed in the lid 30.

  A base 24 is fixed to the bottom surface of the water tank, and the pipe 20 is supported by the base 24. The pipe 20 is a so-called bent pipe whose flow path direction changes by about 90 degrees. One end of the pipe 20 opens in the horizontal direction to form an inflow port. On the other hand, the other end of the pipe 20 opens upward. A flange 21 is provided at the other end of the pipe 20. The inlet side of the pipe 20 is enlarged toward the outside and forms a casing (impeller casing) 25 of the impeller 2 of the underwater mixer 10 described later. That is, in this embodiment, the impeller casing 25 is a part of the pipe 20 and is formed integrally with the pipe 20. However, the impeller casing 25 and the pipe 20 may be formed separately, and the impeller casing 25 may be fixed to the pipe 20. A flange 22 of another pipe 23 is connected to the flange 21 at the other end of the pipe 20.

  The pipe 23 may be configured to guide water into the water tank and may extend outside the water tank. That is, this detachable water supply device may circulate water in the water tank or may transport water outside the water tank. The application of this removable water supply device is not limited at all.

  A guide rod 11 extending substantially in the vertical direction is fixed to the upper part of the pipe 20 on the inlet side. As shown in FIG. 3, one guide bar 11 is provided on each of the left and right sides. The guide rod 11 may be a solid rod, but in this embodiment is a hollow rod. The cross-sectional shape of the guide rod 11 is not limited at all, and may be, for example, a circular shape or a rectangular shape. In the present embodiment, the guide rod 11 is formed in a circular cross section. The number of guide bars 11 is not limited to two, and may be one or three or more. When a plurality of guide bars 11 are provided, the shapes of the guide bars 11 may be the same or different. The lower side of the guide rod 11 is a curved portion 11a that is curved from the vertical direction toward the pipe 20 side. An inclined plate-like stopper 12 is provided at the lower end of the curved portion 11a.

  The underwater mixer 10 includes an underwater motor 1 and an impeller 2 connected to a rotation shaft of the underwater motor 1. The underwater mixer 10 is placed horizontally so that the axial direction of the impeller 2 is substantially horizontal. As shown in FIG. 1, the impeller 2 is accommodated in the impeller casing 25 of the pipe 20 in a state where the underwater mixer 10 is attached to the pipe 20.

  The underwater mixer 10 is provided with a guide member 4 that guides the raising and lowering of the underwater mixer 10 along the guide rod 11. The guide member 4 includes a support plate 9 fixed to the upper part of the underwater mixer 10 and support bars 7a and 7b (see FIGS. 2 and 3) extending in the left-right direction from the left and right sides of the support plate 9. A substantially triangular guide plate 6 orthogonal to the support bars 7a and 7b is fixed to the tips of the support bars 7a and 7b. As shown in FIG. 1, three rollers 5 a, 5 b, and 5 c that protrude laterally from the guide plate 6 are attached to the corners of the guide plate 6. The first roller 5a is located on the pipe 20 side (right side in FIG. 1) of the guide rod 11, and the second roller 5b and the third roller 5c are on the opposite side of the guide rod 11 from the pipe 20 (left side in FIG. 1). ). Thus, the 1st-3rd rollers 5a-5c are located so that the guide rod 11 may be pinched | interposed from both sides, and may comprise the pinching member. A hanging chain 15 is attached to the underwater mixer 10.

  Next, a method for installing the underwater mixer 10 will be described with reference to FIG. When installing the underwater mixer 10, first, the underwater mixer 10 is carried into the water tank through the opening 31 of the lid 30, and the guide member 4 (specifically, the rollers 5 a to 5 c) is engaged with the guide rod 11 in the water. The mixer 10 is lowered. When the guide bar 11 extends outside the water tank, the engagement between the guide member 4 and the guide bar 11 is started before the underwater mixer 10 is carried into the water tank. On the other hand, when the guide bar 11 does not extend outside the water tank, the engagement between the guide member 4 and the guide bar 11 is started after the underwater mixer 10 is carried into the water tank.

  When the underwater mixer 10 passes through the opening 31 of the lid 30 and is guided by the guide rod 11, the attitude of the underwater mixer 10 is inclined such that the axial direction of the impeller 2 faces obliquely downward. Therefore, the planar view length L1 during movement of the underwater mixer 10 is shorter than the planar view length when the underwater mixer 10 is installed. Therefore, the planar view area during movement of the underwater mixer 10 is smaller than the planar view area at the time of installation.

  When the underwater mixer 10 is suspended along the guide rod 11, the rollers 5 a to 5 c of the guide member 4 eventually reach the curved portion 11 a of the guide rod 11. Then, since the rollers 5a to 5c move along the curved portion 11a, the posture of the underwater mixer 10 is changed from the inclined posture to the substantially horizontal posture. Specifically, the underwater mixer 10 rotates with the first roller 5a as a fulcrum. And if the 1st roller 5a and the 3rd roller 5c are latched by the stopper 12, the raising / lowering and attitude | position change of the underwater mixer 10 will be complete | finished. As a result, the impeller 2 is accommodated inside the impeller casing 25 of the pipe 20, and the underwater mixer 10 is attached to the pipe 20 (see FIG. 1).

  At the time of maintenance or the like, the submerged mixer 10 is carried out of the water tank by an operation reverse to the above. That is, by pulling up the suspension chain 15, the underwater mixer 10 is removed from the pipe 20 while changing the posture, and is lifted out of the water tank along the guide rod 11 while maintaining the inclined posture.

  As described above, according to the detachable water feeding device according to the present embodiment, when the underwater mixer 10 is carried into the water tank through the opening 31 of the lid 30, or the underwater mixer 10 is brought out of the water tank through the opening 31 of the lid 30. When carrying out, the underwater mixer 10 is moved in an inclined posture. Therefore, as shown in FIG. 4, the required length A <b> 1 of the opening 31 is not necessarily longer than the length in the longitudinal direction of the underwater mixer 10. That is, the required length A1 of the opening 31 only needs to be longer than the planar view length L1 in the inclined posture. Therefore, according to the present embodiment, the required area of the opening 31 can be reduced.

  In addition, since the impeller 2 of the underwater mixer 10 is housed inside the pipe 20 at the time of attachment, the entire planar view area of the underwater mixer 10 and the pipe 20 at the time of attachment can be kept small. That is, when a part of the underwater mixer 10 is not accommodated in the pipe 20, the total area obtained by adding up the plan view area of the underwater mixer 10 itself and the plan view area of the pipe 20 itself is the plan view area of the entire apparatus. It becomes. On the other hand, in this embodiment, since a part of the underwater mixer 10 and the pipe 20 overlap in plan view, the plan view area of the entire apparatus is smaller than the total area. Therefore, the installation area of the detachable water feeder can be reduced.

  Furthermore, in the present embodiment, the impeller casing 25 is provided not on the underwater mixer 10 side but on the pipe 20 side. Therefore, in the underwater mixer 10, the impeller casing 25 is unnecessary. Therefore, the underwater mixer 10 can be reduced in size and weight. As a result, it is easy to carry in and out the underwater mixer 10.

  The mechanism for changing the posture of the underwater mixer 10 includes a guide rod 11 having a curved portion 11 a and a guide member 4 having rollers 5 a to 5 c that engage with the guide rod 11. Therefore, the underwater mixer can be changed in posture by a simple and inexpensive configuration.

  Next, with reference to FIG. 5, a detachable water feeder according to another embodiment will be described. The water supply device according to this embodiment includes a submersible pump 40 and a pipe 20.

  The pipe 20 has substantially the same configuration as that in the above embodiment. However, in this embodiment, the inlet side of the pipe 20 is formed in a straight pipe shape, not a divergent shape.

  The submersible pump 40 includes a submersible motor 42, an impeller 41 connected to the rotating shaft of the submersible motor 42, and a casing 43. The casing 43 covers the impeller 41 and a part of the underwater motor 42 on the impeller 41 side. The peripheral part of the impeller 41 of the casing 43 is formed in a divergent shape. A guide member 4 that is substantially the same as that of the first embodiment is attached to the casing 43.

  In the present embodiment, in a state where the submersible pump 40 is attached to the pipe 20, the casing 43 and the pipe 20 are smoothly continuous, and a part of the submersible motor 42 is accommodated inside the pipe 20. In other words, the inlet side of the pipe 20 covers a part of the submersible motor 42 and constitutes the casing of the submersible pump 40 together with the casing 43. That is, the pipe 20 constitutes a part of the casing for the submersible pump 40. In addition, the piping 20 does not necessarily need to be integrally formed, and the part which covers the underwater motor 42 and the other part may be assembled so that division | segmentation is possible.

  Also in this embodiment, the submersible pump 40 can be attached and detached in the same manner as in the above embodiment. That is, the installation method and removal method of the submersible pump 40 are the same as those in the above embodiment.

  Therefore, also in the present embodiment, the various effects described above can be obtained. Also in this embodiment, the required area of the opening 31 of the lid 30 can be reduced. Moreover, the installation area of a detachable water feeder can be reduced. Further, the submersible pump 40 can be reduced in size and weight, and attachment and detachment of the submersible pump 40 can be facilitated.

  By the way, in each said embodiment, the curved part 11a is provided in the lower end of the guide rod 11, and the guide member 4 of the underwater mixer 10 or the submersible pump 40 (henceforth the underwater mixer 10 etc.) is moved along the curved part 11a. Therefore, the posture of the underwater mixer 10 or the like is changed. However, the mechanism for changing the posture of the underwater mixer 10 or the like is not limited to the above-described mechanism. For example, as shown in FIG. 6, it is also possible to provide an inclined plate-like stopper 12a at the lower end of the guide rod 11 and omit the curved portion 11a. That is, it is possible to form the guide bar 11 with a straight bar. In this case, when the underwater mixer 10 or the like is lowered along the guide rod 11 in an inclined posture, the roller 5a contacts the stopper 12a, and then the underwater mixer 10 or the like rotates with the roller 5a as a fulcrum. As a result, the posture of the underwater mixer 10 or the like is changed from the inclined posture to the horizontal posture, and the underwater mixer 10 or the like is attached to the pipe 20.

  In the said embodiment, the underwater mixer 10 grade | etc., Was mounted | worn with the inflow port side of the piping 20, and supplied the water in a water tank to the piping 20. FIG. However, the underwater mixer 10 or the like may be mounted on the outlet side of the pipe 20 and supply water from the pipe 20 into the water tank.

  In the said embodiment, the fluid machine which comprises a detachable water supply apparatus was the submersible mixer 10 or the submersible pump 40. However, the fluid machine according to the present invention is not limited to a specific type as long as it carries water while being immersed in water in the water tank.

  The removable water supply apparatus according to the present invention is suitably used in, for example, a sewage treatment facility, a manhole pump station, a pump gate system, and the like. However, the utilization object of this removable water supply apparatus is not limited at all.

  As described above, the present invention is useful for water treatment facilities such as sewage treatment facilities and drainage facilities such as pump gate systems.
