Description

  The present invention relates to a siphon-type overflow device that drops water in a water tank using a drop.

  When fish such as tropical fish are bred mainly for the purpose of viewing, ammonia, sea cucumbers, etc. may be generated in the aquarium due to food left over by fish or excrement such as manure. Thus, if ammonia or a giant sea bream generated in the water tank is left as it is, there is a risk that the fish will get sick, and in the worst case, it may be killed. Moreover, viewing may be hindered by the water in the water tank getting dirty.

  Accordingly, it is necessary to exchange the water in the aquarium. At this time, first, the fish is put in another aquarium, a bucket or the like, and the water in the aquarium is exchanged. However, when exchanging, it is necessary to pick up the fish and move it to another aquarium or bucket, so it is inevitable to touch the body of the fish, and the fish may be damaged and weakened.

  Therefore, an overflow device that does not require exchanging fish to exchange water is useful. Regarding the conventional overflow device, there are the following documents (1) and (2). Document (1) makes it possible to drop water from a sewage in a water tank using a water drop system. Reference (2) is different from what pumps out water in the water tank, and pumps liquid such as kerosene. References (1) and (2) will be described below.

  Document (1) is “Water tank with improved water drop system and filtration device” of Noto 3018619. This device is a water tank and a filtration device that can drop water in the water tank without special work on the water tank provided in the lower part. It is a water tank with an improved water drop system having a bent siphon having a discharge hole, an overflow pipe capable of discharging water to the filter tank, and a filtration device having the system. This device is a tank with a dropping system that allows ammonia generated in aquarium for raising tropical fish, goldfish, etc. It aims at providing the filtration apparatus which has a system, and can drop the water in an aquarium, without accompanying a special work to an aquarium.

  In addition, as can be said for conventional overflow devices in general, there is a problem that a large noise is generated when water is discharged, and abnormal noise may be generated.

  Reference (2) is “Simple pumping pump” of Utility Model 2-85900. This device is a simple pumping pump that easily pumps liquid such as kerosene, and has an air supply port that can be opened and closed at the top of a hose that forms an inverted U-shaped siphon tube. Enclose in a large-diameter tube of the required length, tightly and tightly contact the upper part of the large-diameter pipe with the suction pipe, and reduce the lower part in a tapered shape to form a close-contact part and a predetermined gap between the suction pipe This is a simple pumping pump that forms a space, inserts a blow-in pipe in an airtight manner from the upper part of the large-diameter pipe, and arranges a throttle part at the lower end of the other discharge pipe. This device is not designed to suck up by generating negative pressure by the restoring force of the elastic body, unlike the conventional pumping manual pumping pump. The purpose is to provide a pump.

  However, the idea of the document (1) is that water enters from the filter provided on the water injection hole side of the bent siphon's water tank and falls to the lower filter tank, and the filter is below the water tank. It is difficult to adjust the water level. Moreover, since the pipe | tube is not provided in the inside of the bending siphon through which water passes, it is fundamentally different from this invention. Further, in the device of Document (1), since the water injection hole side of the bent siphon on the water tank side is fixed without rotating, it is difficult to finely adjust the water injection amount depending on the water level in the water tank. Furthermore, since the device of Document (1) does not have a water level fine adjustment pipe inside the bent siphon, fine adjustment of the water level may be difficult.

  Further, the idea of the document (2) relates to a simple pumping pump that pumps up liquid in the receiving container from the suction pipe and discharges it from the discharge pipe, and pumps up liquid such as kerosene easily. This is different from the siphon-type overflow device that drops the water in a simple aquarium. Further, since neither the suction pipe nor the discharge pipe is provided inside, it is essentially different from the present invention. Furthermore, the idea of the reference (2) is that the upper part of the suction pipe is embedded in a large-diameter pipe of a required length, and the upper part of the large-diameter pipe is hermetically adhered to the suction pipe, and the suction pipe does not rotate. Therefore, it is difficult to finely adjust the amount of water that enters from the suction pipe.

  In consideration of the above problems, the siphon-type overflow device of the first invention includes a U-shaped double pipe mounted on a water tank composed of a first pipe and a second pipe provided therein, and the U-shaped double pipe. A siphon-type overflow device comprising a water supply pipe connected to the first pipe of the type double pipe and a drooping pipe connected to the second pipe, and a honeycomb-shaped separation passage is provided at both ends of the drooping pipe. It is formed.

  A siphon-type overflow device according to a second aspect is characterized in that the water supply pipe of the siphon-type overflow device according to claim 1 is rotatable.

  A siphon type overflow device according to a third aspect of the present invention is characterized in that a water level fine adjustment pipe is provided from a side end portion of a water supply pipe of the siphon type overflow device according to claim 1 to a drooping pipe.

  A siphon-type overflow device according to a fourth aspect of the present invention is the siphon-type overflow device according to any one of claims 1 to 3, wherein the bottom portion of the water supply pipe and the upper end portion of the drooping pipe are used as the same, and the second pipe and the second pipe It is characterized in that the lower end of each is the same.

  According to the first invention, the U-shaped double pipe is composed of a first pipe and a second pipe provided in the first pipe, and a honeycomb-shaped separation passage is formed at both ends of the drooping pipe. Therefore, the water flowing from the second pipe to the drooping pipe becomes a water bubble while taking in the air in the first pipe, and is exhausted and drained to the lower end of the drooping pipe. Siphon can be made at a fast stage using all the pipes and water can be circulated.

  According to the second invention, since the water supply pipe of the overflow device is rotatable, the water level in the water tank can be easily changed.

  According to the third invention, since the water level fine adjustment pipe is provided in the overflow device, the water level in the water tank is raised by extending the water level fine adjustment pipe upward according to the situation. be able to. If the water level fine adjustment pipe is positioned below the water level adjustment hole, the water level can be stabilized on the lower surface of the water level adjustment hole.

  In the former case, that is, when the water level fine adjustment pipe is in the upward direction of the water level adjustment hole, the air that is taken in from the water level adjustment hole and flows into the first pipe is bypassed from the water level fine adjustment pipe to the droop pipe. The water density is lowered, the falling speed of water is lowered, and the water surface rises. Therefore, if this example is adopted, the desired water level can be maintained. Moreover, the sound (swirl sound etc.) generated in the vicinity of the water level adjustment hole and the sound (water current sound etc.) when flowing into the first pipe are suppressed, and further, the discharge of the food floating on the water surface is prevented.

  In the latter case, that is, when the water level fine adjustment pipe is in the downward direction of the water level adjustment hole, water is also taken from the water level fine adjustment pipe, the water density in the drooping pipe is increased, the falling speed is increased, the water surface is lowered, and the water tank The water level inside is stabilized in the vicinity of the water level adjustment hole. Therefore, suspended matter such as an oil film from the surface of the water surface can be discharged rationally.

  In the former and the latter, the present invention, as described above, quickly adjusts the water density in the downpipe, makes the drainage capacity follow the pumping capacity of the pump, and has a strong water level stability. When using, it is possible to use various pumps. Therefore, when using the present invention, in most cases, it is not necessary to purchase a new pump, and the existing pump can be used as it is. Useful in terms.

  Moreover, since the inside of the drooping pipe is in a water bubble state and an aeration effect for dissolving air into water is obtained, installation of an air pump may be unnecessary. Therefore, in this case, the entire equipment can be slimmed down, and the cost spent on the air pump can be suppressed, which is useful in terms of cost.

  According to the fourth invention, the bottom of the water supply pipe and the upper end of the drooping pipe are the same, and the lower end of the second pipe and the second pipe are the same, so the so-called priming water stretched in the second pipe is Regardless of the water level in the aquarium, it can remain without being affected by it, and the water level can be adjusted continuously.

  When the present invention is actually used, in addition to the present invention and the water tank 11, a lower water tank (not shown) provided below the water tank 11 and water stored in the lower water tank are pumped up and returned to the water tank. Use a pump (not shown). Although the present invention illustrated in FIGS. 10 to 12 has been described based on the first embodiment, the same applies not only to the first embodiment but also to the second embodiment.

  First, as a previous stage in FIG. 6, so-called priming water is poured into the empty first pipe 1, second pipe 2, water supply pipe 5, and adapter 7 in which no water 11 b is contained. There are various methods for putting the priming water 11b into the inside of the present invention. For example, the method of immersing the priming water into the inside of the present invention by immersing the present invention in the water tank 11 filled with the water 11b, There is a method in which water 11b is introduced from the lower end portion 8b of the drooping pipe 8, the present invention is swung, and priming water is introduced into the present invention.

  Then, after the water 11b has entered the inside of the present invention, when the present invention is started with the horizontal portion 1c of the first pipe 1 set to the atmosphere side 12, a part of the water 11b inside the first pipe 1 flows down. The interior of the second pipe 2 is filled with so-called priming water. In addition, a state in which the first embodiment is mounted on the edge of the water tank 11 is shown in FIG.

  First, as a first step, the water level 11 a in the water tank 11 is below the bottom side 5 c of the water supply pipe 5 of the first pipe 1. On the other hand, the water level 11 a on the water supply pipe side 1 a of the first pipe 1 is on the horizontal line of the bottom part 5 c of the water supply pipe 5, and the water level 11 a on the droop pipe side 1 b in the first pipe 1 is drooping on the first pipe 1. It exists in the vicinity of the upper end part 8a of the drooping pipe 8 provided in the pipe side 1b. That is, the water level 11 a on the water supply pipe side 1 a and the drooping pipe side 1 b of the first pipe 1 is on the line A.

  In the next second stage, as shown in FIG. 7, when the water 11b pumped up from the lower water tank by the pump is drawn into the water tank 11, the water level adjustment hole 5a provided in the water supply pipe 5 of the first pipe 1 is reached. It will be filled with water 11b. Then, a small amount of water 11b flows from the upper end portion 8a of the drooping tube 8, and a small amount of water 11b is discharged from the drooping tube 8 in the form of a water bubble 11c.

  In the third stage in FIG. 8A, the air in the first pipe 1 is exhausted in the form of water bubbles 11c in the previous stage, and the first pipe 1, the second pipe 2, the water supply pipe 5, and the adapter 7 are exhausted. The inside of is filled with water 11b, so to speak, the device of the present invention is ready to function as a siphon. Therefore, a large amount of water 11b enters from the upper end portion 8a of the drooping tube 8, and a large amount of water 11b is discharged from the lower end portion 8b side of the drooping tube 8.

  8-2, since a large amount of water 11b is discharged into the water tank 11 in FIG. 8-1, the water level 11a in the water tank 11 is lowered below the water level fine adjustment pipe 6, and further in the water tank 11. Since the water level 11 a is below the water level fine adjustment pipe 6, air enters the water level fine adjustment pipe 6, and air also enters the inside of the droop pipe 8, and the water 11 b discharged from the droop pipe 8 is It becomes a water bubble 11c shape.

  In FIG. 9, which is the fifth stage of the present invention, when the pumping of the water 11b using the pump from the lower water tank into the water tank 11 is stopped, the mass drainage from the downpipe 8 as shown in FIG. 8-1 is stopped. The water level 11a in the water tank 11 falls below the water level adjusting hole 5a and the overflow is stopped. When the water 11b is pumped into the water tank 11 again, the process returns to the second stage in FIG.

  Thus, in the present invention, the overflowed water 11b in the water tank 11 is mainly drained from the hanging pipe 8, the drained water 11b is stored in the lower water tank, and the water 11b stored in the lower water tank is It is a structure that is pumped up and returned to the water tank 11.

  6-9, although the example which used a lower water tank and a pumping pump other than this invention and the water tank 11 was demonstrated, this invention is not limited to this example. This example is an exemplification, and when the same effect is obtained with the substantially same configuration as the present invention, it belongs to the technical scope of the present invention. For example, without using a lower aquarium or a pump, the water 11b drained from the downpipe 8 is not returned to the aquarium 11, but flows into a drainage ditch or given to a plant. It is good also as a structure of supplementing another new water 11b.

  When the components of the third embodiment are roughly classified based on FIG. 10, a U-shaped double pipe 3 having a substantially U shape, a water supply pipe 5 having a substantially T shape, and a drooping structure having a substantially L shape. It consists of a tube 8.

  The U-shaped double pipe 3 includes a first pipe 1 and a second pipe 2 (not shown in the figure) provided in the first pipe 1, and the first pipe 1 and the second pipe 2 are A single U-shaped double tube 3 is formed by combining them. Moreover, the 1st pipe | tube 1 which comprises the U-shaped double pipe | tube 3 can be classified into the site | part of the water supply pipe side 1a, the horizontal part 1c, and the drooping pipe side 1b.

  The water supply pipe 5 of the third embodiment includes a water supply main pipe 15 and a connecting pipe 16. A connection hole 15a is provided in the water supply main pipe 15, and one end of the connection pipe 16 is inserted into the connection hole 15a. Further, a coupling hole 17 is provided on the water supply pipe side 1 a of the first pipe 1, and the other end of the connecting pipe 16 is inserted into the coupling hole 17. By comprising in this way, the 1st pipe | tube 1 and the water supply pipe | tube 5 which comprise the U-shaped double pipe 3 are united.

  A detachable cap 4 is provided on the upper end portion 5 e of the water supply pipe 5. If the cap 4 is removed while the water 11b is flowing, the air enters the inside, so the flow of the water 11b stops. Then, when the cap 4 is inserted again and the water level rises near the bottom of the connecting hole 15a, the water 11b flows again. Thus, intermittent drainage is possible using the tidal level of the water level in the water tank 11.

  A water level adjusting hole 5 a is provided below the water supply main pipe 15. Water enters from the water level adjusting hole 5a. The water 11b that has entered from the water level adjustment hole 5a reaches the drooping pipe 8 through the second pipe 2 and is drained from the dripping pipe 8.

  A detachable cap 4 is provided at the lower end 1a1 on the water supply pipe side 1a and the lower end 1b1 on the drooping pipe side 1b of the first pipe 1 constituting the substantially U-shaped pipe. The collected garbage can be taken out.

  The substantially L-shaped drooping pipe 8 is roughly divided into a connecting pipe 16a, an adapter 7, a cock portion 18, and a drooping main pipe 8c.

  A connecting hole 15b is provided in the hanging pipe side 1b of the first pipe 1 constituting the U-shaped double pipe 3, and one end of the connecting pipe 16a is inserted into the connecting hole 15b. Then, the other end of the connecting pipe 16a and the upper end portion 7a of the adapter 7 are connected, and the lower portion of the adapter 7 and the upper end portion 18a of the cock portion 18 are coupled. And the lower end part 7c of the cock part 18 and the drooping main pipe 8c are combined. By comprising in this way, the 1st pipe | tube 1 and the substantially L-shaped hanging main pipe | tube 8c are united. Since the connecting pipe 16 and the hanging main pipe 8 c have different diameters, the connecting pipe 16 and the hanging main pipe 8 c are connected by the adapter 7.

  When the cock 18c of the cock part 18 is closed, the drainage stops, so that the function of the apparatus can be stopped at an arbitrary water level 11a, and the desired pumping level can be maintained by stopping the pump.

  Although the water supply pipe | tube 5 can be rotated like FIG. 11, the inclination of the water supply pipe | tube 5 can be made into various angles by the desired water level 11a. Further, by removing the cap 4 and changing the inclination angle of the water supply pipe 5, the water level adjusting hole 5 a provided below the water supply pipe 5 allows not only the water 11 b in the surface layer area of the water tank 11, but also the middle and low water areas. Therefore, the sewage can be discharged by adjusting the inclination angle of the water supply pipe 5 to the layer that is sewed and desired to be drained. The description of other configurations is in accordance with the description of FIG.

  As shown in FIG. 12, the drooping main pipe 8 c is provided so as to extend across the adapter 7 and the cock portion 18, and the lower part of the adapter 7 is constituted only by the drooping main pipe 8 c.

  Further, the bottom 16b of the connecting pipe 16 and the upper end 8c1 of the drooping pipe 8 are the same. That is, the bottom 16b of the connecting pipe 16 and the upper end 8c1 of the drooping pipe 8 are on the same line C.

  A honeycomb-shaped separation passage 9 is provided on the upper end portion 8c1 side and the lower end portion 8c2 side of the hanging main pipe 8c, and the separation passage 9 has a configuration in which the thin tubes 10 are gathered together.

  As shown in FIG. 13, since the second pipe 2 is provided inside the first pipe 1 constituting the U-shaped double pipe 3, the second pipe 2 is shaped like the shape of the first pipe 1. Is substantially U-shaped.
