Description

[Detailed description of the invention] Industrial application field This invention relates to a water faucet that is attached to fish culture equipment such as fish ponds and fish tanks, and at the same time efficiently supplies oxygen during watering. It was designed to be done.

Conventional technology Fish farming requires constant water supply and supplementation of underwater oxygen.
In order to replenish oxygen in the water, air can be directly blown into the water in the fish pond or in the water supply channel through a blower or cylinder, or a rotary blade wheel connected to a motor can be used to agitate the water.
Air bubbles are continuously generated by drawing in external air along the blade axle.

Problems that the invention aims to solve However, these methods are expensive as they require blowers and rotary wheels, and are unrelated to changes in the flow rate of the water supply channel. It is difficult to adjust the amount of bubbles generated, and the stirring type has the disadvantage that the range in which bubbles are generated is limited.

Means to Solve the Problems In order to overcome these problems with conventional water taps, water is supplied by a specific sprinkling system that forcibly draws air from the atmosphere, and the amount of water supplied is Oxygen supplementation can be done at the same time, and in this way no power is required. This idea was developed with this point in mind; in other words, it adjusts the amount of water sprinkled, and at the same time supplies oxygen according to the amount of water sprinkled without requiring any power, and it can be used in a 360-degree direction. It is designed to scatter water.

That is, this invention has a stepped portion 4 on the inner circumferential surface, and a large number of through holes 5 in the peripheral wall above the stepped portion 4.
A bell-shaped lid 2 is attached to the upper end of a cylindrical body 1 which is open at the upper and lower ends and has a plurality of rows of vertically disposed around the cylindrical body 1. The valve body 3 is mounted on the cylindrical body 1 at a height substantially in line with the center of the through holes 5 in the bottom row, and a disc-shaped valve body 3 is installed in advance in the cylindrical body 1 at a height above the stepped portion 4. This is a water faucet for fish culture, in which the lower end of a spindle 15, which is screwed into the center of a lid 2, is rotatably fixed around a valve body 3.

Example An example of this invention will be explained with reference to the drawings.
The whole is assembled by inserting a cylindrical body 1, a lid 2, and a valve body 3, each made of hard synthetic resin, into the cylindrical body 1, and then covering the upper end and fixing the lid 2 on top. It is assembled in.

The cylindrical main body 1 is formed as a cylindrical body whose lower end is connected to and attached to a required water supply pipe, and has a stepped portion 4 on the inner peripheral surface, and a large number of holes arranged at regular intervals on the peripheral wall above the stepped portion 4. Through holes 5 are opened in two rows, upper and lower. In addition, in the drawing, the through holes 5 are arranged in two rows, but may be arranged in three or more rows. Four female screw fittings 6 are embedded in the peripheral wall from the upper end, and guide ridges 7 are vertically provided on the inner peripheral surface.

The lid 2 is made into a bell shape, and has a screw hole 9 with a female screw tube 8 embedded in the center, and four bolt holes 10 near the periphery. When this lid 2 is mounted on the cylindrical body 1, the lower end of its hanging edge 11 is located at approximately the same height as the center of the lower row of through holes 5, and is in contact with the outer peripheral surface of the cylindrical body 1. The size is such that an annular gap of considerable width is formed between them.

The valve body 3 has a spindle mounting hole 12 having a groove on the inner surface at the center, a groove 13 vertically provided on the circumferential surface to engage with the guide ridge 7 of the cylindrical body 1, and a groove on the lower surface. There is an annular packing 14 along the periphery.
is installed vertically. On the upper surface of this valve body 3, a spindle 15 made of a stainless steel threaded rod is inserted with its lower end into the spindle mounting hole 12 via O-rings 16, 16, and a retaining ring 17 is engaged with the threaded part. It is rotatably attached to the valve body 3.

As described above, these cylindrical body 1, lid 2, and valve body 3 are mounted on step 4 with valve body 3 placed inside cylindrical body 1, and its groove 13 engaged with guide ridge 7. At the same time, a lid 2 is placed on the top surface of the cylindrical body 1, and the spindle 15 of the valve body 3 is screwed into the screw hole 9 of the cylindrical body 1. Then, stainless steel bolts 18 are inserted into the bolt holes 10...
are inserted into each, and screwed into the female threaded metal fitting 6 and tightened to be assembled integrally. Reference numeral 19 denotes a rotating handle that is engaged with a spindle 15 that projects upward from the lid 2.

Function This device has the above-mentioned structure, and is used by being connected to the upper end of a water supply pipe installed in a fish pond or a shellfish pond, for example, in the state shown in FIG. That is,
When the spindle 15 is rotated and the valve body 3 is pushed down to the stepped portion 4 which is the valve seat, the water supply is blocked, but when the spindle 15 is raised, the water supply passes through the outer periphery of the valve body 3 and the water is passed through. Water is ejected outward from the holes 5..., and this ejected water is diffused 360° by the through holes 5... uniformly provided on the circumferential surface of the cylindrical body 1, and is refracted downward by the arcuate inner surface of the lid 2. This refraction causes a sufficient amount of external air to be drawn in and dispersed over the water surface of the fishpond.

That is, as described above, the hanging edge 11 of the lid 2
has a considerable gap with the outer peripheral surface of the cylindrical main body 1, and the lower end is provided at a height corresponding to approximately the center of the through holes 5 in the bottom row. ...The water jet ejected from the lower half is sprayed horizontally in a 360° range, but the upper half is blocked by the inner surface of the hanging edge 11 and becomes a downward cylindrical stream, where it spreads horizontally. A vortex is generated due to the collision between the current and this downward flow, and the external air below the hanging edge 11 is drawn in to perform the above-mentioned oxygen replenishment.In this way, oxygen is replenished into the fish pond by sprinkling water mixed with air and oxygen. The amount of replenishment can be correspondingly increased by rotating the spindle 15 to increase the amount of water, that is, by increasing the downward flow through the through holes 5 in the upper row and increasing the degree of collision with the horizontal flow. . The increase in the downward flow increases bubbling on the fish pond water surface, further promoting oxygen supply.

Effects of the invention As described above, this invention can supply oxygen without requiring power by simply attaching it to the top of the water supply, which has pressure such as natural head or water supply. It has many advantages, such as easy adjustment of the amount of water and oxygen supplementation, and the fact that the whole can be disassembled for convenient cleaning.
