[0003]

The conventional submersible pump is intended to be set at the bottom of the water, and is not provided with a function for setting the depth of the dive and ascent of the dive, and when it is particularly required, it is suspended. There are not many examples of pumps that have the functions of floating and self-propelling under the method of. It is a surface floating type that does not have the function of floating submergence even for filtering dirt that floats in the bath water for home use, and because it is used in the bath, there is a danger of electric shock at normal voltage and dry batteries are used. It also has a single function.

According to the present invention, the dive of the pump can be set to the required depth, the pump automatically floats when the operation is stopped, and even when used in the bath, there is no risk of electric shock and a drive capable of adding more than a single function is provided. The purpose of this pump is to provide a highly functional and safe submersible pump depending on the purpose of the pump, such as a pump with power, or a mechanism that allows the pump water absorption function to correspond to the water surface and the bottom of the water. Another object of the present invention is to provide a method for manufacturing a dive levitation propulsion adjusting device.

Insertion mounting is more efficient.

Further, in a heavy-duty pouring / discharging device for diving, which has a large pumping capacity, a large depth distance from the surface of the water to the bottom of the water without a constant working area depth, and a deep diving device, a valve composed of a column faucet is required. The desired effect is high.

[00013] An electric valve constituted by a faucet with an L-shaped water hole for pouring and discharging heavy objects for diving by remote control of floating underwater in and out of water is necessary for setting a target position. .

Further, in order to widen the work area on the water surface and enhance the efficiency of efficient purification and recovery work, the self-propelled movement can be performed without being fixed at a fixed position. It is efficient to provide a direction control ring in combination with the propulsion spout.

Water starts to flow through the filter installation chamber to the pump suction port, and it becomes a work drive, and the water flow from the water guide hole as the primary water flow is stopped by the pressure receiving operating panel and the water stop device attached to it. When the drive is stopped, it also serves as the discharge port.The setting of the desired work area depth from just below the water surface adjusts the rising position of the pressure receiving operating panel into the air chamber, limiting the water supply capacity to the heavy load chamber. Free depth setting is carried out by.

Further, in a pump in which the upper end of the float is set below the surface of water before driving the pump and the main working area of the bottom of the water and its vicinity are mainly closed, it is possible to feed, stop, and discharge water to and from a heavy load room by remote operation underwater.

The present invention has the effects described below because it is constructed as described above.

In a submersible pump in which the float water inlet at the upper end of the float is set above the water surface, water is absorbed from a water guide hole configured so that the water level for diving is located on the upper surface of the pump water inlet, and is installed below the water outlet. Water is sent to the diving spout to start diving, water is absorbed from the target float water suction port, and water supply to the diving spout is stopped by driving stop, and ascent is performed.

A wire shaft pump driven by a wire shaft is used instead of an electric internal motor driven pump as a pump drive source constituted by the float and the submersible levitation device having the above-mentioned structure, so that an electric shock accident in water or in a bath can be completely eliminated. It can be prevented. Also, connecting a telescopic shaft above the drive axis of the wire shaft pump or in the lateral direction is effective as an auxiliary function for floating in the submersible and for propulsive movement in the lateral direction.

Further, as a submersible levitation device for a submersible pump used in a water surface working area with a water surface area of 5 m ² or less, a heavy load chamber is formed by inserting a pressure receiving operation adjustment into an air chamber forming a float, and a heavy load chamber is formed at the bottom. In the case of a pump with a water pipe attachment port for sending water, where the upper end of the float is set above the water surface, a water guide hole is formed with the water surface position as the pump water intake port upper end for water passage for diving. The water pipe branched from the pump diversion pipe sends water as a heavy load to the heavy load chamber to start diving and to set the water depth as a heavy load to set the target depth position. When stopped, the pressure-sensitive operating panel is pushed down by the compression pressure in the air chamber to be discharged and floated.

As a submersible levitation device for a submersible pump used in the water surface work area of 10 m ^{2 or} less, water is passed through a water guide hole for primary diving to a target depth, and water is absorbed from the upper end of the float. When it starts, it stops the flow of water through the water guide hole, but as a water stop device when the water transfer capacity is large in proportion to the pump, a water stop plate with water holes at the bottom of the pressure receiving operating panel is hung. A more effective mechanism is one that is installed and vertically penetrates through a water guide hole that is provided in the lateral direction of the lower pump suction port of the float.

Further, as an equipment for discharging heavy substances of a submersible pump used in the vicinity of the water bottom where the upper end of the pre-driving float is below the water surface, a large amount of water is sent to the heavy goods chamber, and the volume of the air chamber is increased proportionally. In order to prevent the force that tends to discharge the heavy load chamber due to the pressure to push down the pressure receiving operating panel, a valve composed of a columnar water plug is attached to the water supply pipe used for water supply as a heavy load. Is a mechanism for connecting the pressure receiving actuating plate with a connecting rod, and assisting the water pressure to push up the pressure receiving actuating plate through the connecting rod, and to assist the pushing down effect of the faucet by reducing the water sending pressure by stopping the drive.

[0003] The water supply and the water supply stop forming the L water hole as a water supply and discharge device for heavy dive for diving to determine the depth setting corresponding to the change of the undulation of the water bottom and the volume condition of the recovered material near the water bottom. While the discharge is not performed by mounting the valve driven by an electric motor by remote control in and out of the water, the contact sensing frame attached to the bottom of the pump makes it possible to stop the water supply and correct the levitation to the target depth by contacting the bottom of the water.

Further, it is effective for maintaining airtightness and for injecting air at a pressure higher than normal pressure and for injecting other gas into the float air chamber which is basically constituted by the air chamber, the heavy load chamber, and the pressure receiving operating plate described above. In addition, the vertical bellows-shaped tube also expands and contracts satisfactorily due to vertical movement due to water supply and drainage. It is also effective to mount a spring in the air chamber as an up-and-down auxiliary mechanism for the pressure receiving operating plate.

Further, a propulsion mechanism that expands the water absorption surface instead of a single point by collecting the propulsion spout and the directional control ring is efficient. It is effective to switch the water flow of the propulsion spout. Inversion movement is also possible by mounting the operation ring.
