Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, in particular to a water distribution device of a multifunctional submersible pump. Background Art

[0002] Aeration pump is a kind of equipment commonly used in fishery breeding industry. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be short of oxygen. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water and threaten the living environment of the fish.

[0003] Aeration pumps generally spray water into the air, mix it with air, and then sprinkle it in the water to achieve the purpose of oxygenating the water surface. However, for example, an aerator for fish pond farming with patent number 2020113875971 directly sprinkles water into the air from the water nozzle, so the degree of mixing with air is low and the oxygenation effect is not ideal.

[0004] In the prior art, oxygen pumps basically use asynchronous motors, which have low efficiency and small lift, resulting in unsatisfactory water spray diameter and water volume, and are also greatly restricted in their use scenarios. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a water distribution device for a multifunctional submersible pump. The problem to be solved by the utility model is: how to use it in more scenarios to meet personalized needs and how to improve the oxygenation effect.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a water distribution device of a multifunctional submersible pump, the submersible pump includes a permanent magnet synchronous motor and a pump assembly, the permanent magnet synchronous motor includes a motor housing and a motor shaft, the pump assembly includes a volute and an impeller arranged in the volute, a water inlet connector is fixedly connected between the volute and the motor housing, the upper end of the motor shaft passes through the water inlet connector and is fixed to the impeller, a water outlet section is welded and fixed to the upper part of the volute, the water outlet section has a water passage running through the upper and lower parts, and the upper part of the water outlet section is detachably fixedly connected with a water distribution device with an adjustable oxygenation area.

[0007] The submersible pump of this scheme can be used for flood control, drought resistance, seawater aquaculture and fish pond oxygenation. Since the water distribution device is a detachable device, when the water distribution device is not installed, the water outlet section is directly connected to the water outlet pipe to exert the pumping function of the multi-functional pump for flood control or drought resistance. After installing the water distribution device on the water outlet section, it can be used for seawater aquaculture or fish pond oxygenation, and then the aeration area can be adjusted by the water distribution device to adapt to seawater aquaculture or fish pond oxygenation. Permanent magnet synchronous motor is used as the power, which is high-speed and efficient, powerful, low-voltage, soft-start, low-noise operation, with overheating, overload and other protection functions, and significant energy-saving effect. The impeller is directly fixed on the motor shaft so that the impeller and the motor shaft have good concentricity, which can better drive the impeller to rotate. The detachable and adjustable aeration area water distribution device set on the water outlet section can meet the personalized needs of different occasions. The integrated design of the permanent magnet synchronous motor and pump assembly is convenient to carry and use.

[0008] Furthermore, the water distribution device includes a body guide and a water divider, the body guide includes an integrally formed conical mounting portion and a cylindrical fixing portion, the interior of the cylindrical fixing portion is a water outlet channel connected to the water flow channel, the conical mounting portion has a water outlet connected to the water outlet channel, the outer lower end of the cylindrical fixing portion is provided with an external thread, the upper part of the water outlet section has an internal thread, the cylindrical fixing portion and the water outlet section are threadedly fixed, and the water divider is adjustably fixed on the conical mounting portion.

[0009] This solution uses threaded fixing of the cylindrical fixing part and the water outlet section. The threaded fixing can be easily disassembled and can also well fix the cylindrical fixing part and the water outlet section. An adjustable water distributor is installed on the conical mounting part and a permanent magnet synchronous motor is used as the power. It is high-speed and efficient, with strong power and can also adjust the size of the oxygenation area.

[0010] Furthermore, the water divider includes a concave-convex water diversion body, the concave-convex water diversion body and the conical mounting portion have the same inclination angle, the bottom middle of the concave-convex water diversion body has an adjustment boss 1 protruding downward, the conical mounting portion has an adjustment boss 2 in the middle, and when the lower end surface of the adjustment boss 1 abuts against the upper end surface of the adjustment boss 2, it is the minimum water flow gap between the concave-convex water diversion body and the conical mounting portion, and adjustment bolts are provided on the adjustment boss 1 and the adjustment boss 2.

[0011] The concave-convex water-dividing body of the present invention has the same inclination angle as the conical mounting portion, and the water-passing gap formed between the two also has an inclination angle. The motor shaft of the permanent magnet synchronous motor drives the impeller to rotate and sucks in a large amount of water, which flows from the water outlet throttling to the guide body, and then flows from the water outlet on the conical mounting portion of the guide body to the water-passing gap between the concave-convex water-dividing body and the conical mounting portion. Since the water-passing channel in the water outlet throttling and the water outlet channel in the guide body are waterways with large areas, and the water-passing gap between the concave-convex water-dividing body and the conical mounting portion is relatively small, the large water flow brought up by the high power of the permanent magnet synchronous motor passes through the water-passing gap and forms a transverse annular spray out. The concave-convex water-dividing body increases the longitudinal area of ​​the water-passing gap, increases the area of ​​the water flow sprayed longitudinally, increases the spray height of the water flow, greatly increases the contact area between the water flow and the air, increases the contact area between water and oxygen, increases the surge oxygenation, and the falling water drops form a circle of "rainstorm" area, with a good oxygenation effect. The distance between the concave-convex water dividing body and the conical mounting portion can be adjusted by adjusting the bolts to realize water flow gaps of different sizes, thereby ensuring the controllability of the oxygenation area and meeting individual needs.

[0012] Furthermore, the conical mounting portion extends outwardly to form a conical annular portion, the conical annular portion and the concave-convex water dividing body form a concave-convex composite flow channel, the concave-convex composite flow channel is connected to the water outlet, and the adjusting bolt adjusts the space size of the concave-convex composite flow channel.

[0013] This solution uses a permanent magnet synchronous motor whose motor shaft drives the impeller to rotate and sucks in a large amount of water from the water outlet throttling to the guide body, and then flows from the water outlet on the conical mounting portion of the guide body to the water gap between the concave-convex water dividing body and the conical mounting portion. The concave-convex composite flow channel formed by the concave annular portion and the concave-convex water dividing body is an extension of the above-mentioned water gap. Since the water passage in the water outlet section and the water outlet channel in the guide body are water passages with large water cross-sectional areas, and the water cross-sectional area of ​​the concave-convex composite flow channel is relatively small, the large amount of water brought up by the high power of the permanent magnet synchronous motor After passing through the water gap, the water forms a horizontal ring-shaped jet. Due to the addition of a straight-line extended conical ring-shaped part, the water flow ejected in the horizontal ring-shaped jet is tilted upward and more evenly and regularly, which increases the height of the water jet. In addition, the concave-convex water dividing body increases the longitudinal area of ​​the water gap, increases the area of ​​the water jet in the longitudinal direction, and further increases the water jet height. The water spray diameter can reach more than 15 meters, which greatly increases the contact area between the water flow and the air. The surge increases oxygen, and the falling water drops form a circle of "rainstorm" area, which has a good oxygenation effect.

[0014] Furthermore, the adjusting boss 2 has an inlaid adjusting nut, and the adjusting bolt passes through the adjusting boss 1 and is screwed with the adjusting nut. The distance between the concave-convex water diversion body and the conical mounting portion can be adjusted by screwing the adjusting bolt with the adjusting nut to achieve different sizes of water gaps, thereby ensuring the controllability of the oxygenation area and meeting personalized needs.

[0015] Furthermore, the guide body and the water divider are made of plastic material, preferably nylon, which is not easily deformed and more stable after long-term immersion.

[0016] Furthermore, the water outlet joint is made of plastic material, preferably nylon material, which is durable, not easily deformed and more stable after long-term immersion.

[0017] Furthermore, the impeller is made of stainless steel and fixed by welding. The impeller is preferably made of 304 stainless steel, and the impeller is welded in both directions to meet the requirements of high speed operation and durability.

[0018] Furthermore, the water distribution device is provided with a plastic float on the outer cover, and the plastic float is fixed to the water inlet connector by a chain. The plastic float is made of ABS engineering plastics and has a flat design. The whole machine is fixed to the float with a chain and floats on the water surface, so it will not sink into the mud, and it is easy to install and use. The whole machine can be set in the middle of the pond through the plastic float, and the water in the middle and lower layers can be pumped to the upper layer and lifted up to mix with the air to increase oxygen, which is convenient to carry and use.

[0019] Furthermore, the outer periphery of the water outlet section is provided with a plurality of tower-shaped mounting parts, the upper diameter of the tower-shaped mounting parts is smaller than the lower diameter, and the plurality of tower-shaped mounting parts are arranged in sequence up and down. The tower-shaped mounting parts can better fix the water pipe when used for external water pipe connection.

[0020] Compared with the prior art, the technical effects of the utility model are as follows: 1. With the permanent magnet synchronous motor as the power, the motor has high efficiency, energy saving and electricity saving. The large water flow brought up by the high power of the permanent magnet synchronous motor forms a horizontal annular spray after passing through the water gap. Due to the addition of a conical annular portion extending in a straight line, the water flow sprayed out in the horizontal annular shape is sprayed upward in an inclined manner and more uniformly and regularly, thereby increasing the height of the water flow spray. In addition, the concave-convex water dividing body increases the longitudinal area of ​​the water gap, increases the area of ​​the water flow spraying in the longitudinal direction, and further increases the spray height of the water flow. The water spray diameter can reach more than 15 meters, greatly increasing the contact area between the water flow and the air, and the surge increases oxygen. The falling water drops into a circle of "rainstorm" area, and the oxygenation effect is good; 2. The water outlet section, the guide body and the water divider are made of plastic material, which is durable, not easy to deform and more stable after long-term immersion; 3.

The motor shaft 2 is fixed to the rotor and rotates with the rotor. The pump assembly includes a volute 3 and an impeller 4 arranged in the volute 3. The volute 3 and the motor housing 1 are fixedly connected to the water inlet connector 5. The upper end of the motor shaft 2 passes through the water inlet connector 5 and is fixed to the impeller 4. The rotation of the impeller 4 increases the static pressure energy and kinetic energy of the liquid, and transports the water flow from the outside of the water inlet connector 5 to the water outlet section 6. The permanent magnet synchronous motor is used as a power source, which has high speed and high efficiency, strong power, low voltage, soft start, low noise operation, overheating, overload and other protection functions, and significant energy saving effect.

[0029] like Figure 2 , 3As shown, a water outlet section 6 is welded and fixed on the upper part of the volute 3. The water outlet section 6 has a water passage 601 that passes through from top to bottom. A water diversion device 7 with an adjustable oxygenation area is detachably fixedly connected to the upper part of the water outlet section 6.

The surface of the concave annular portion 714 is an inclined plane, and the space gap from the concave-convex water divider body 721 to the inclined plane is high and low, forming a circle of concave-convex composite flow channels 8a with orderly concave and convex arrangements. When the water flows out from the concave-convex composite flow channel 8a, it will be ejected upward along the surface of the conical annular portion 714 according to the shape of the concave-convex composite flow channel 8a, thereby increasing the spray height and spray diameter of the water flow, increasing the contact area between the water flow and the oxygen in the air, and achieving a good oxygenation effect.
