Description

  The present invention relates to a drain outlet structure and a drainage method in a pool, particularly a swimming pool.

  Conventionally, there is a drain outlet as part of the water circulation circuit to drain the injected water into the pool, or to collect the water and purify it with a filter, etc. Is provided. This drainage port is usually formed in the bottom or inner wall of the pool.

  A metal strainer plate having a comb shape, a lattice shape, or a concentric shape is attached to the opening of the drain port. The drain pipe and water in the pool are communicated with each other through the strainer plate. As described above, the water collected from the drainage port is purified through a filter and mixed with a disinfectant such as hypochlorous acid or a chemical for the purpose of preserving the hygienic condition of the pool. It is re-delivered from the water inlet formed in

  This also applies to a flowing water pool. In this flowing water type, flowing water is formed by sampling, pressurizing, and returning to the inside of the pool. It has been laid out and designed.

  In any case, since the pool is collecting water by sucking the water in the pool with a pump from the drain outlet, it is devised so that a human body, clothes and the like are not drawn into the drain outlet. In addition, if a circulation drainage port is formed at the bottom of the pool, the person's legs in the pool may be sucked in, the person in the dive may be sucked in and drowned. It is customary to provide a drainage outlet for water stop at a high position.

  In particular, when a drain outlet is provided in the inner wall of the pool, the strainer plate provided in the opening is fixedly secured to the inner wall surface of the pool, a fixed frame, etc. by fastening members such as bolts, nuts, screws, etc. Etc., so that they are not easily removed.

  However, in this structure, it is necessary to keep the pool hygienic, so the drain outlet must be periodically cleaned. In order to remove the strainer plate each time, the above-mentioned fastening member is removed, and again Tightening work is required. Repeating this operation may cause turning or unevenness on the head or corner of the bolt or nut. Of course, the fact that the bolts and nuts are positioned in the pool itself has a risk of damaging the human body. However, the deformation of the bolts and nuts further increases the risk.

In addition, due to the structure described above, running water hits the strainer plate, and in addition, vibration of the water absorption pump is also applied, the strainer plate resonates, generates large energy, and loosens the fastening member as a result. There is a risk of inviting.
Although the applicant investigated the prior art documents related to the present invention, the applicant could not find any documents that seem to be particularly relevant to the present invention regarding the drainage or outlet of the pool.

  The problem to be solved by the present invention is that, when the strainer plate is fixed to the opening of the drain outlet, if a fastening element such as a bolt or a nut is used, a part of the fastening element is located in the pool and the human body may be damaged. In addition, the fastening element resonates with various vibration elements, and there is a possibility that it may drop off unintentionally, and in the unlikely event that foreign matter enters the drainage pipe, If it cannot be reversed, the treatment is significantly delayed, and if the foreign body is a human body, it is greatly involved in life and death.

  In order to solve this problem, a drain outlet structure of a pool according to the present invention is fixed to a drain opening formed on a side wall surface of the pool with a frame having a guide groove at least on the left and right sides. The strainer plate is detachably provided in the guide groove of the frame, and the upper opening of the drainage port is equipped with a lid that can be opened and closed, and is formed on the side wall surface of the pool. A step groove is formed at the opening edge of the drain port, and a guide groove is formed by combining a flat frame having a water passage port with the step portion, and a strainer plate is detachably provided in the guide groove, and above the drain port. The opening is equipped with a lid that can be freely opened and closed, and is provided with an inclined recess in a part of the bottom surface of the drain port formed on the side wall surface or the bottom surface of the pool. A panel with a drainage port formed on the side wall surface of the pool that is slightly larger than the strainer plate, and has an elastic material such as urethane, silicon, or rubber on the periphery. The panel is fixed by a fixing element such as a turnbuckle.

  In addition, the drainage method for a pool according to the present invention branches a drainage pipe communicating with a drainage port formed on the bottom surface of the pool, a main drainage pump is disposed on one side, and a push-back pump is disposed on the other side. When the foreign matter enters the drainage pump, the reverse pump is operated and pushed back to the discharge port.

  The pool drainage structure and drainage method according to the present invention are configured as described above. For this reason, there is no need for fastening elements such as bolts and nuts to fix the strainer plate, and there is no risk of damaging the human body, and the fastening elements will not fall off due to vibration or other factors. The strainer plate cannot be removed at all.

  In addition, according to the drainage method described above, even if the main pump cannot be reversed, the sub-pump can be used to reverse-pressure feed the invading foreign substance into the drainage pipe and push it back to the drainage port. Prompt handling is possible, and it is possible to save lives.

  This was realized by configuring as in the embodiment shown as a drawing.

  Next, a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a drain outlet structure of a pool embodying the present invention, FIG. 2 is a diagram showing another example in which a strainer plate is similarly attached, FIG. 3 is a diagram showing a structure in the drain outlet, and FIG. The figure which shows a panel and FIG. 5 are the figures which similarly show the arrangement | positioning of a drain pipe and a pump.

  In these drawings, reference numeral 1 denotes a frame fixed to the opening of the drain of the pool. This frame 1 is substantially U-shaped with its upper part opened, and a continuous guide groove 2 is formed at least on the left and right sides of the inner wall peripheral surface here. Then, the strainer plate 3 is fitted into the guide groove 2 from above. With this configuration, the strainer plate 3 is detachably positioned without any fastening elements such as bolts and nuts, and the outer peripheral edge of the strainer plate 3 enters the guide groove 2. The strainer plate 3 can be removed only by human work. The frame 1 can be easily formed by punching a stainless steel plate and bending it with a press. And the stopper of the strainer plate 3 can be made by tapering the bottom of the guide groove 2 formed at least on both sides.

  Further, a lid body that can be freely opened and closed by rotating via a hinge, for example, is provided at the upper part of the drainage port having a structure in which the strainer plate 3 is fitted to the frame 1. By making the lid body non-porous, it is usually possible to walk on the upper surface, and even if a coin, a key, or the like is dropped, there is no possibility of falling into the drain port.

  In addition, it is assumed that the frame 1 is installed corresponding to the opening of the drain port, but the frame 1 is disposed obliquely from the upper edge of the opening edge to the lower part of the drain port, and the strainer plate 3 is attached in the oblique direction. Further, it is possible to make a modified application such that the frame 1 has a depth, the guide groove has an arc shape that descends from the front to the rear, and the strainer plate 3 is formed in a curved plate shape.

  Further, such a configuration can be realized by designing as shown in FIG. That is, first and second step portions 5 and 6 are formed on the front opening edge of the drain port 4, and a frame 7 having a quadrangle or upper opening and a water passage port is fitted and fixed to the first step portion 5. The guide groove 8 is formed by the frame 7 and the second step portion 6. The upper strainer plate 3 can be mounted in the guide groove 8.

  On the other hand, a recess 9 can be formed in a part of the chamber-shaped drain outlet 4, particularly in a part of the bottom surface in the back, and a pipe 10 is connected to the recess 9, and the recess is formed by the drain pipe 11. 9. Forcibly, it is possible to remove the accumulated water in the drain port 4. This action, together with the use of a water stop panel, which will be described later, makes it possible to perform various operations in the drain outlet 4 without completely draining the water in the pool at the time of inspection or emergency.

  Further, when the work is performed in the drain port 4 described above, a water stop panel 12 as shown in FIG. 4 is used. The panel 12 has a size slightly larger than that of the strainer plate 3, and the peripheral edge thereof is covered with a material 13 having elasticity such as urethane, silicon, or rubber. This panel 12 is fixed to the opening of the drain port 4 using a fixing tool such as a turnbuckle, for example. When the water in the drain port 4 is drained, the water in the pool flows into the drain port 4. This makes it possible to work in the drain 4. The peripheral elastic material 13 buffers the panel 12 that is subjected to water pressure. This water-stopping action enables immediate response in an emergency, so that underwater work is not required even during inspection, and water as a resource is not wasted and discarded.

  Furthermore, when a drain outlet is provided on the bottom surface of the pool, there are cases where it is provided as a single unit and a case where a drain groove is formed. Then apply the lid. In this case, it is possible to form a stepped part overlapping each other on the edge of each strainer plate, or to hold it with a T-shaped presser bracket, etc., and the outer edge along the groove has an L-shaped cross section from above. Apply a split-type presser foot and slide it in place. In this way, it is only necessary to hold only the outermost metal fitting with a fastening element such as a bolt, and there is no trouble of fastening for each strainer plate, and it is usually impossible to lift the strainer plate upward. . And when the stepped parts are overlapped, it is required to remove the strainer plate in order, and it is impossible to remove the strainer on its own, but places where it can be removed every few meters as necessary are formed It is also possible.

  In particular, when the main pump 15 connected to the drain pipe 14 and sucking and discharging the water in the pool is non-reversible such as a multistage type, a branch pipe 16 is formed in the drain pipe 14, The branch pipe 16 may be provided with a sub-pump 17 that rotates to push water back. With such a configuration, in the unlikely event that foreign matter is mixed into the drainage pipe 14, it is possible to push the foreign matter back to the discharge port by reversely rotating the main pump 15, but the main pump 15 cannot be reversely rotated. Even in such a case, the above-described operation can be performed by operating the sub pump 17.

  The configuration according to the present embodiment is as described above. Here, when the strainer plate 3 is attached to the obliquely arranged frame 1, both sides of the strainer plate 3 are restrained by the frame 1, and the upper end portion is fastened with fastening elements such as bolts. Is also possible. In this configuration, the heads of bolts and the like are located at a location deeper than the inner wall of the pool, so there is no risk of injury due to contact with the human body, etc., and there is some backlash with a margin in the diagonal direction. Even if there is, there will be no need for perfect fastening work. In this case, it is possible to use a snap or clip with a spring interposed instead of a bolt or the like. In addition, with respect to the panel 12, a hook point to which a turnbuckle is attached in advance is provided in the pool inner wall, a turnbuckle set in advance on the panel 12 can be used, and further, a U-shaped bracket formed on the panel 12 can be turned on. A buckle can be attached. In short, the panel 12 can be installed from either the front surface or the back surface of the strainer plate 3.

  It is also possible to provide a system in which a switch is provided on the lid and the water absorption pump is stopped when the lid is opened. Further, if an unexpected operation or pump stoppage occurs, an alarm is sounded. Or, it can be configured to notify by turning on a lamp.
