Description

Technical Field

[0001] This utility model relates to the technical field of marine and land-based pumps, specifically to a marine and land-based pump. Background Technology

[0002] The global mariculture industry is developing rapidly, and China, as a major marine fishery nation, is accelerating the construction of its "blue granary," leading to a surge in demand for efficient and environmentally friendly aquaculture equipment. Traditional seawater pumps suffer from problems such as low flow rate, poor environmental adaptability, high energy consumption, and insufficient corrosion resistance, making them unsuitable for deep-sea aquaculture and recirculating aquaculture systems. Coastal fisheries need to accommodate both land-based recirculating aquaculture and offshore cage farming, necessitating pump equipment with dual-use capabilities to reduce redundant equipment costs and improve efficiency.

[0003] Therefore, the research objective of this utility model is to design a dual-purpose pump that can switch modes between different marine and land scenarios, and that has corresponding anode components that can be detachably installed on a filter screen suitable for marine use to effectively mitigate the corrosion rate of seawater and extend its service life. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the present invention provides a descent pump that can effectively solve the technical problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] A amphibious pump, comprising:

[0007] The pump body has corresponding outlet and inlet ports at its upper and lower ends, respectively. A filter screen or flange is detachably and fixedly installed on the outside of the inlet port. The filter screen has many liquid permeable holes evenly distributed around its circumference.

[0008] The annular anode is detachably installed on the filter screen at the water inlet via a corresponding limiting mechanism, and is connected to the pump body via a corresponding metal wire.

[0009] The limiting mechanism includes a limiting cylinder fixedly installed inside the filter screen by support rods evenly distributed around the circumference, and an annular airbag fixedly installed on the inner side wall of the limiting cylinder; when the filter screen is installed, the top of the limiting cylinder abuts against the outside of the water inlet of the pump body; the annular anode is horizontally fitted inside the limiting cylinder, and the annular airbag, after being inflated, abuts against and presses against the circumference of the annular anode and fixes the annular anode;

[0010] The adjustment mechanism includes a connecting rod movably installed within the connecting rod through a corresponding elastic element. When the annular airbag is inflated and expands towards the connecting rod, it pushes the connecting rod outwards, and the elastic element is compressed. When the annular anode is consumed and shrinks, the elastic element resets, causing the connecting rod to gradually move inwards and push the annular airbag. The annular airbag expands outwards on one side of the annular anode, continuing to press and fix the annular anode.

[0011] The inner wall of the limiting cylinder is recessed inward and has an insert groove that communicates with the through hole. The annular airbag is glued and fixed inside the insert groove by an adhesive method. The inner end of the annular airbag is provided with an air inlet that extends through to the outer wall of the limiting cylinder. Its outer end is configured as an arc or wave shape that matches the annular anode.

[0012] The through holes are respectively inclinedly arranged on the upper and lower sides of the annular airbag, and the through holes on the upper and lower sides are staggered. The through holes on the upper side of the annular airbag are inclined upward, and the through holes on the lower side of the annular airbag are inclined downward. The two ends of the through holes are respectively connected to the inner side wall of the limiting cylinder and the mounting groove. The elastic element is sleeved on the outside of the connecting rod, with its upper end fixed to the through hole and its other end fixed to the connecting rod. The outer end of the connecting rod is flush with the inner side wall of the limiting cylinder. The annular airbag is provided with a corresponding pushing part extending towards the through hole. After the annular airbag is inflated, the pushing part expands towards the through hole and pushes the connecting rod outward so that its outer end is placed on the upper and lower sides of the annular anode.

[0013] The inner top of the motor cover of the pump body is equipped with a corresponding integrated sensor, which includes a vibration sensor, a flow sensor and a current sensor. The integrated sensor is electrically connected to the pump body and is connected to an external intelligent frequency conversion control cabinet through corresponding cables. The motor in the pump body is a frequency conversion motor.

[0014] The cable is fixedly installed on the pump body through a corresponding cable outlet seat and extends outward to the outside of the pump body. It is also fixedly installed on the handle of the pump body through corresponding clamps and collars.

[0015] The inner diameter of the annular anode is not less than the inner diameter of the pump body inlet.

[0016] The annular anode is made of carbon steel.

[0017] Advantages of this utility model:

[0018] 1) The amphibious pump of this utility model allows for convenient replacement of the filter screen or national standard flange according to different usage environments or locations. Based on the modular and quick switching of the applicability of the amphibious pump, the sacrificial anode added to the filter screen is used to effectively slow down the corrosion rate of the amphibious pump in seawater and extend its service life. Furthermore, the anode is set as a ring structure and installed at the water inlet of the pump body to ensure that the corrosion current must pass through the ring anode before flowing to the protected structure, effectively ensuring that the pump body is protected from corrosion.

[0019] 2) As the mass and volume of the anode component decrease during use, it will loosen as it is consumed when tightened with bolts or nuts. This loosening will cause high-frequency displacement and vibration of the anode component during pump operation, affecting the accuracy of pump performance measurements and potentially impacting the pump's lifespan. Therefore, this invention addresses this issue by fixing a limiting cylinder to the filter screen and bonding an annular airbag to the embedded groove on the inner wall of the limiting cylinder. The flexible compression of the annular airbag fixes the annular anode component, allowing for a more precise fit and improved stability. When the airbag inflates, it pushes the connecting rod outwards, compressing the elastic element and accumulating elastic potential energy. As the annular anode component gradually wears down, the pushing force of the annular airbag on the connecting rod gradually decreases, allowing the elastic element to recover and, under the influence of elastic potential energy, reset the connecting rod. This pushes the annular airbag, causing the gas inside to expand outwards towards the limiting cylinder, thus maintaining the compression and fixation of the annular anode component. This utility model combines an added limiting mechanism and an adjustment mechanism for automatically adjusting and fixing annular anode parts. The fixing method is a flexible connection, which not only improves its applicability but also enhances the fixing effect. The fixing method is convenient and simple.

[0020] 3) The present invention further sets the through hole to be inclined, and its two ends are respectively connected to the outside of the limiting cylinder and the embedded groove. When the annular airbag is inflated, it will push the connecting rod outward to the limiting cylinder, thereby forming a limiting protection part on the upper and lower sides of the inner side of the limiting cylinder. This can further support and limit the annular anode part, which is initially the heaviest, improve its fixed stability, and prevent it from falling.

[0021] 4) This utility model adds a comprehensive sensor consisting of a vibration sensor, a flow sensor, and a current sensor to detect the vibration, flow, and current of the pump body in real time. The data is combined to predict the wear and blockage risk of the pump body, which facilitates timely maintenance and unblocking, and improves the service life of the amphibious pump. Furthermore, by connecting the pump body's variable frequency motor to an intelligent variable frequency control cabinet, the rotation frequency of the pump body motor can be flexibly adjusted according to different usage scenarios of the amphibious pump, thereby reducing water supply energy consumption by more than 10%.

Detailed Implementation

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0027] refer to Figure 1-3 A amphibious pump, comprising:

[0028] Pump body 1, with corresponding outlet 101 and inlet 102 at the upper and lower ends of the pump body 1 respectively. A corresponding filter screen 2 or flange is detachably and fixedly installed on the outer side of the inlet 102. The filter screen 2 has many liquid permeable holes evenly distributed around its circumference.

[0029] The annular anode 3 is detachably installed on the filter screen 2 at the water inlet 102 via a corresponding limiting mechanism 4, and is connected to the pump body 1 via a corresponding metal wire (not marked). This creates a potential difference through the annular anode 3 to prevent corrosion of the pump body 1. The end of the metal wire is embedded inside the annular anode block 3 to ensure that the connection between the metal wire and the anode block does not fall off when the anode block is consumed.

[0030] The limiting mechanism 4 includes a limiting cylinder 402 fixedly installed inside the filter screen 2 by support rods evenly distributed around the circumference, and an annular airbag 401 fixedly installed on the inner side wall of the limiting cylinder 402; when the filter screen 2 is installed, the top of the limiting cylinder 402 abuts against the outside of the water inlet 102 of the pump body 1; the annular anode 3 is horizontally fitted inside the limiting cylinder 402, and after the annular airbag 401 is inflated, it abuts against and presses against the circumference of the annular anode 3 and fixes the annular anode 3.

[0031] The debugging mechanism 5 includes a limiting cylinder 402 with corresponding through holes 4021 at both the upper and lower ends of the annular airbag 401. The through holes 4021 are evenly distributed around the circumference of the limiting cylinder 402. The debugging mechanism 5 includes a connecting rod 502 movably installed in the through holes 4021 via a corresponding elastic element 501. When the annular airbag 401 is inflated and expands into the through holes 4021, it pushes the connecting rod 502 outward, and the elastic element 501 is compressed. When the annular anode 3 is worn down, the elastic element 501 resets, causing the connecting rod 502 to move inward gradually and push the annular airbag 401. The annular airbag 401 expands outward on the side of the annular anode 3 to continue to press and fix the annular anode 3.

[0032] This utility model's amphibious pump allows for convenient replacement of the filter screen 2 or national standard flange according to different usage environments or locations. Based on the modular and rapid switching of the amphibious pump's applicability, a sacrificial anode is added to the filter screen 2 to effectively slow down the corrosion rate of the amphibious pump in seawater, extending its service life. Furthermore, the anode is set as a ring structure and installed at the water inlet 102 of the pump body 1, ensuring that the corrosion current must pass through the ring anode 3 before flowing to the protected structure, effectively guaranteeing the protection of the pump body 1 from corrosion.

[0033] The inner wall of the limiting cylinder 402 is recessed inward and has an inlay groove that communicates with the through hole 4021. The annular airbag 401 is glued and fixed inside the inlay groove by an adhesive method. The inner end of the annular airbag 401 is provided with an air inlet 4011 that extends through to the outer wall of the limiting cylinder 402 and its outer end is configured as an arc or wave shape that is adapted to the annular anode 3.

[0034] Since the mass and volume of the anode components will decrease during use, they will loosen as they are worn out when tightened with bolts or nuts. This loosening will cause high-frequency displacement and vibration of the anode components during pump body 1 operation, thereby affecting the accuracy of pump body 1 performance measurement. Furthermore, the vibration generated by high-frequency displacement may affect the service life of pump body 1. Therefore, this utility model fixes a limiting cylinder 402 on the filter screen 2, and adheres and fixes an annular airbag 401 in the embedded groove on the inner side wall of the limiting cylinder 402. The annular anode 3 is fixed by the flexible pressing of the annular airbag 401, which can better fit the shape of the annular anode 3 for fixation, thus improving the stability of the fixation. Furthermore, when the airbag inflates, it pushes the connecting rod 502 outward, compressing the elastic element 501 and storing elastic potential energy. As the annular anode 3 gradually depletes, the pushing force of the annular airbag 401 on the connecting rod 502 gradually decreases, and the elastic element 501 gradually recovers. Under the action of elastic potential energy, it drives the connecting rod 502 to reset, pushing the annular airbag 401 to expand the gas inside to the outside of the limiting cylinder 402, thereby maintaining the pressurized fixation of the annular anode 3. This utility model combines the added limiting mechanism 4 and adjustment mechanism 5 for automatic adjustment and fixing of the annular anode 3. The fixing method is a flexible connection, which not only improves its applicability but also enhances the fixing effect. The fixing method is convenient and simple.

[0035] The through holes 4021 are respectively inclinedly arranged on the upper and lower sides of the annular airbag 401, and the through holes 4021 on the upper and lower sides are staggered. The through holes 4021 on the upper side of the annular airbag 401 are inclined upward, and the through holes 4021 on the lower side of the annular airbag 401 are inclined downward. The two ends of the through holes 4021 are respectively connected to the inner wall of the limiting cylinder 402 and the mounting groove. The elastic element 501 is sleeved on the outside of the connecting rod 502 and its upper end is fixed. The connecting rod 502 is fixed to the connecting hole 4021 at one end and the connecting rod 502 at the other end. The outer end of the connecting rod 502 is flush with the inner wall of the limiting cylinder 402. A corresponding pushing part 4012 is provided on the annular airbag 401 extending into the connecting hole 4021. After the annular airbag 401 is inflated, the pushing part 4012 expands into the connecting hole 4021 and pushes the connecting rod 502 outward so that its outer end is placed on the upper and lower sides of the annular anode 3.

[0036] This utility model further sets the through hole 4021 to an inclined shape, and its two ends are respectively connected to the outside of the limiting cylinder 402 and the embedded groove. When the annular airbag 401 is inflated, it will push the connecting rod 502 outward to extend the limiting cylinder 402, thereby forming a limiting and protective part on the upper and lower sides of the inner side of the limiting cylinder 402. This can further support and limit the annular anode part 3, which is initially the heaviest, improve its fixed stability, and prevent it from falling.

[0037] The inner top of the motor cover of the pump body 1 is provided with a corresponding integrated sensor 6. The integrated sensor 6 includes a vibration sensor, a flow sensor and a current sensor. The integrated sensor 6 is electrically connected to the pump body 1 and is connected to the external intelligent frequency conversion control cabinet 7 through a corresponding cable 8. The motor in the pump body 1 is a frequency conversion motor.

[0038] The cable 8 is fixedly installed on the pump body 1 through a corresponding cable outlet seat and extends outward to the outside of the pump body 1. It is also fixedly installed on the handle of the pump body 1 through corresponding clamps and collars.

[0039] The inner diameter of the annular anode 3 is not less than the inner diameter of the inlet 102 of the pump body 1.

[0040] The annular anode element 3 is made of carbon steel.

[0041] This utility model adds a comprehensive sensor 6 consisting of a vibration sensor, a flow sensor, and a current sensor to detect the vibration, flow, and current of the pump body 1 in real time. The data is then combined to predict the wear and blockage risk of the pump body 1, which facilitates timely maintenance and unblocking, and improves the service life of the amphibious pump. Furthermore, by connecting the variable frequency motor of the pump body 1 to an intelligent variable frequency control cabinet 7, the rotation frequency of the motor of the pump body 1 can be flexibly adjusted according to different usage scenarios of the amphibious pump, thereby reducing water supply energy consumption by more than 10%.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
