Description

Technical Field

[0001] This invention relates to the field of seawater pump technology, specifically to a seawater pump with an impact-resistant and anti-deviation mounting structure. Background Technology

[0002] Seawater pumps are widely used in complex environments such as ships, offshore platforms, and coastal water supply and drainage, where they operate under high disturbance and impact conditions for extended periods. They are primarily used for transporting marine media. During actual operation, seawater pumps are continuously subjected to multiple alternating loads, including wave impacts, ship swaying and pitching, and equipment resonance. The operating environment is harsh and the vibration and impact are highly random.

[0003] Traditional seawater pumps mostly use a fixed flange rigid locking installation structure to be rigidly connected and fixed to the mounting base. They rely solely on fixing holes and bolts to achieve single-point planar locking. The overall installation structure lacks buffer and shock absorption design and has a single form of limit constraint. After long-term operation under alternating loads, it is very easy to cause various installation failures and equipment operation hazards.

[0004] Firstly, the rigid fixed structure without buffer and shock absorption will directly transmit the alternating load generated by the impact of sea waves and the vibration of the ship to the pump body and mounting bolts. Under long-term reciprocating action, the bolts are prone to fatigue and loosening, causing the pump body to move and shift, which affects the long-term stability of the seawater pump.

[0005] Secondly, traditional flanges rely solely on single-plane bolts for fixing and limiting, resulting in a single limiting dimension and a lack of multi-directional clamping and constraint structures. This makes it impossible to provide three-dimensional limiting protection for the pump body. When the pump body is disturbed by external forces, it is prone to displacement, which can lead to problems such as pipeline sealing failure and wear and damage to the precision structure inside the pump.

[0006] Furthermore, the traditional flange installation structure has a fixed locking position, low overall limit redundancy, and the force is concentrated on a few bolt points. Under continuous alternating loads, it is prone to local overload and insufficient structural offset reserve, making it difficult to adapt to the harsh working conditions of long-term high disturbance and high impact at sea. Summary of the Invention

[0007] To address the aforementioned technical deficiencies, this invention provides a seawater pump with an impact-resistant and anti-deviation installation structure. By using a buffered, split-type mounting base combined with adjustable clamping and a multi-point circumferential limiting structure, it achieves impact-resistant and multi-directional anti-deviation installation and fixation, thereby improving the installation reliability of the seawater pump under marine operating conditions.

[0008] To address the problems of existing technologies, this invention provides a seawater pump with an impact-resistant and anti-deviation mounting structure, comprising: a pump body, a connecting seat fixedly mounted at the bottom of the pump body, the connecting seat having two sets of positioning holes symmetrically arranged along a plane passing through the pump body axis; a split mounting base disposed below the connecting seat, the split mounting base including two transverse fixing plates and a buffer member disposed between the two transverse fixing plates, the buffer member being spaced apart along the length direction of the transverse fixing plates; an adjustable clamping seat assembly for clamping the peripheral wall of the top corner of the connecting seat is mounted on the top of each transverse fixing plate; two-section folding arms are hinged to both ends of each transverse fixing plate, and vertical threaded holes are provided at the rotation positions of the transverse fixing plates and the corresponding two-section folding arms, with locking bolts passing through the threaded holes to lock the transverse fixing plates and the two-section folding arms onto the component to be installed, thereby limiting the circumferential movement of the seawater pump.

[0009] Preferably, buffer pads are provided on the bottom sides of the threaded holes of the transverse fixing plate and the two-section folding arm.

[0010] Preferably, each transverse fixing plate has two oppositely arranged bearing seats at its top, and a retaining seat is provided at the middle position between the two bearing seats; a rotating rod is rotatably assembled between the two bearing seats, and the retaining seat has a through hole for the rotating rod to pass through; a clamping seat is provided between the retaining seat and the two adjacent bearing seats, and the clamping seat can be slidably arranged along the axial direction of the rotating rod.

[0011] Preferably, the outer wall of the rotating rod is provided with a bidirectional thread, and the clamping seat is threadedly engaged with the bidirectional thread; both ends of the rotating rod are respectively mounted on rotating bearings in corresponding bearing seats; and the two sides of the retaining seat are respectively provided with stoppers for limiting the rotation of the rotating rod.

[0012] Preferably, the clamping seat is a three-sided clamping structure, and the clamping seat cooperates with the transverse fixing plate to form a four-sided clamping structure for clamping the corners of the connecting seat; the lower end face of the clamping seat is flush with the upper end face of the transverse fixing plate.

[0013] Preferably, the clamping seat has a vertically opening vertical limiting hole, and the vertical limiting hole and the positioning hole on the connecting seat are arranged vertically opposite each other.

[0014] Preferably, the stop is a stop nut, which is threadedly connected to the rotating rod, and one end face of the stop nut can fit against the outer wall of the retaining seat.

[0015] Preferably, one end of the rotating rod extends outward from the bearing seat to form an operating rotating part.

[0016] Preferably, the bottom of the clamping seat extends downward to form a guide portion, and a guide groove is provided on the transverse fixing plate along the axial direction of the rotating rod, and the guide portion is slidably assembled in the guide groove.

[0017] Preferably, the buffer is an adjustable external spring damper.

[0018] The advantages of this invention compared to the prior art are: 1. A flexible buffer installation structure is formed by using a split mounting base with buffer components and buffer pads. The damping structure dissipates the alternating loads generated by the hull's turbulence and wave impact, reduces the direct transmission of impact force to the pump body and mounting bolts, slows down bolt fatigue and loosening, improves the equipment's impact resistance, and reduces the probability of vibration-induced failures.

[0019] 2. The adjustable clamping seat assembly forms a four-sided circumferential positioning structure for the pump body connection seat. Combined with the vertical locking structure and the two-section folding arm multi-point circumferential locking structure, a multi-dimensional limiting constraint is constructed. This makes up for the shortcomings of the traditional flange which only relies on single-plane bolts for limiting. It can constrain the multi-directional displacement of the pump body, reduce the possibility of displacement during pump operation, and reduce the damage caused by displacement of pipelines and internal pump structure.

[0020] 3. The adjustable clamping structure combined with the foldable multi-point locking structure allows for fine-tuning of the clamping and locking positions according to the actual installation stress, making the installation stress more uniform and dispersing the bearing pressure of a single bolt point. This enhances the limit redundancy and anti-offset reserve of the installation structure, strengthens the limit reliability of the overall structure under long-term alternating loads, and adapts to the harsh operating environment of high disturbance and high impact at sea.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figures 1 to 4 As shown, a seawater pump with an impact-resistant and anti-deviation mounting structure includes: a pump body 1, a connecting seat 1a fixedly disposed at the bottom of the pump body 1, the connecting seat 1a having two sets of positioning holes symmetrically arranged along a plane passing through the axis of the pump body 1; and a split mounting base 2 disposed below the connecting seat 1a, the split mounting base 2 including two transverse fixing plates 2a and a buffer member 2b disposed between the two transverse fixing plates 2a, the buffer member 2b being spaced apart along the length direction of the transverse fixing plates 2a.

[0032] The aforementioned buffer component 2b adopts an adjustable external spring damper. Operators can adjust the pre-compression of the external spring and the buffer stroke of the damping medium according to the wave level, hull pitching frequency, and equipment resonance amplitude in the operating sea area. This allows for targeted matching of vibration and impact loads of different intensities, solving the technical drawbacks of traditional fixed buffer structures such as poor adaptability, limited shock absorption effect, and inability to be adjusted as needed. This gives the installation structure a more adaptable shock absorption capability.

[0033] Under conditions of hull pitching and wave impact, the instantaneous impact energy is absorbed by the elastic deformation of the spring, and then the mechanical vibration energy is converted into heat energy and slowly dissipated through the damping effect of the damping medium, so as to achieve the gradual release of impact load, rather than rigidly resisting the impact.

[0034] The adjustable external spring damper's buffering mechanism reduces the amount of vertical and lateral bidirectional vibration stress transmitted upwards to the pump body 1, physically isolating the alternating load from continuously damaging the pump body 1's mounting structure. Simultaneously, the adjustable external spring damper provides bidirectional compression buffering, ensuring uniform force distribution on the bottom support of the pump body 1 and preventing structural micro-tilts and assembly gap misalignment caused by concentrated loads on one side. Under long-term operation, it effectively avoids various faults such as fatigue loosening of mounting bolts, misalignment of the mounting structure, base gap movement, and slight displacement of the pump body 1, while continuously maintaining the original installation accuracy of the pump body 1.

[0035] See Figure 2 , Figure 3 and Figure 5 As shown, each horizontal fixing plate 2a has an adjustable clamping seat assembly 2c installed on its top for clamping the peripheral wall of the top corner of the connecting seat 1a.

[0036] Compared to traditional installation methods, traditional seawater pump mounting flanges are integral fixed structures with non-adjustable hole positions and limit dimensions. Due to factors such as component machining tolerances, on-site assembly errors, and base installation deviations, problems such as loose clamping, excessive gaps on one side, and uneven stress are easily encountered. After the equipment starts operating, the gap position will continuously experience slight wobbling, which over time can lead to pump body misalignment, seal failure, and pipeline damage. In contrast, the adjustable clamping structure allows for gap adjustment based on the actual machining dimensions of the connecting seat 1a, the on-site assembly gap accuracy, and the equipment's operating stress state. This ensures a perfect fit to the outer contour of the connecting seat 1a, eliminating the assembly gaps and wobbling space inherent in traditional structures.

[0037] The two sets of symmetrically arranged adjustable clamping seat assemblies 2c can be clamped and aligned synchronously during operation, ensuring that the four corners of the connecting seat 1a are evenly stressed and avoiding assembly problems such as local suspension or local compression.

[0038] Meanwhile, the adjustable clamping seat assembly 2c adopts an integrated structure design with front adjustment and rear locking. After adjustment, the clamping state can be fixed by the mechanical locking structure, which will not cause gap rebound or clamping loosening due to marine vibration and impact. It can always maintain a tight clamping assembly state, providing a solid and stable assembly foundation for the subsequent multi-dimensional anti-deviation system of horizontal limit, vertical locking and circumferential constraint, and improving the installation reliability of seawater pumps under complex working conditions.

[0039] See Figures 2 to 5 As shown, each horizontal fixing plate 2a has a two-section folding arm 2a3 hinged at both ends. The horizontal fixing plate 2a and the corresponding two-section folding arm 2a3 have vertical threaded holes at their rotation positions. The locking bolts pass through the threaded holes to lock the horizontal fixing plate 2a and the two-section folding arm 2a3 onto the component to be installed, so as to limit the circumferential movement of the seawater pump.

[0040] The two-section folding arm 2a3 adopts a segmented hinge structure, and its unfolding angle can be freely adjusted. Compared with the single fixed hole of the fixed flange, this multi-point, adjustable locking structure can form multiple sets of circumferential constraint points. Under the conditions of seawater pump start-up and shutdown impact, lateral wave impact, and ship hull torsion and sway, it can limit the circumferential rotation, angular deviation and lateral movement of the pump body 1, avoid the problems of circumferential misalignment, pipeline twisting and seal leakage that occur after long-term operation of traditional equipment, and improve the equipment's anti-offset redundancy and working condition adaptability.

[0041] See Figures 3 to 5As shown, buffer pads 3 are provided on the bottom sides of the threaded holes of the transverse fixing plate 2a and the two-section folding arm 2a3.

[0042] A buffer pad 3 is added to the bottom of the threaded locking hole to isolate the metal from hard contact, so as to avoid metal extrusion deformation, surface wear and structural looseness defects under high frequency vibration, and protect the structural integrity of the transverse fixing plate 2a, the two-section folding arm 2a3 and the mounting base.

[0043] Meanwhile, the buffer pad 3 has excellent damping and shock absorption performance, which can specifically absorb the subtle high-frequency vibrations transmitted by the base, make up for the shortcomings of the bottom large-stroke buffer 2b in absorbing small-amplitude vibrations, and achieve a graded shock reduction effect of large impact damping dissipation and small vibration absorption by the pad, thereby avoiding the concentrated accumulation of vibration loads at the bolt tightening point and reducing the probability of bolt fatigue damage.

[0044] By using a dual-layer buffer system that works together to reduce the transmission of external vibration and impact to the pump body 1, the overall structure's impact resistance is improved, the service life of the mounting bolts and plate structure is extended, and the long-term stability of the equipment is ensured.

[0045] See Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, each transverse fixing plate 2a has two oppositely arranged bearing seats 2a1 on its top, and a retaining seat 2a2 is provided in the middle between the two bearing seats 2a1; a rotating rod 2c1 is rotatably assembled between the two bearing seats 2a1, and the retaining seat 2a2 has a through hole for the rotating rod 2c1 to pass through; a clamping seat 2c2 is provided between the retaining seat 2a2 and the two adjacent bearing seats 2a1, and the clamping seat 2c2 can be slidably arranged along the axial direction of the rotating rod 2c1.

[0046] The rotating rod 2c1 is supported by bearing seats 2a1 arranged symmetrically at both ends. The bearing seats 2a1 are equipped with rotating bearings, which can reduce the frictional resistance during the rotation of the rotating rod 2c1 and ensure that the rotating rod 2c1 rotates smoothly without deviation.

[0047] The fixed centering seat 2a2 is a fixed centering positioning structure with no positional offset or shaking. It can separate the clamping adjustment ranges on the left and right sides and limit the maximum adjustment stroke and minimum clamping distance of the clamping seats 2c2 on both sides, so that the adjustment stroke of the left and right clamping seats 2c2 always remains completely symmetrical and synchronously equal, avoiding the problems of unilateral adjustment offset and uneven stroke.

[0048] See Figure 3 , Figure 7 and Figure 8As shown, the outer wall of the rotating rod 2c1 is provided with a bidirectional thread, and the clamping seat 2c2 is threadedly engaged with the bidirectional thread; both ends of the rotating rod 2c1 are respectively mounted on the rotating bearings in the corresponding bearing seats 2a1; the two sides of the retaining seat 2a2 are respectively provided with stoppers 2c3 for restricting the rotation of the rotating rod 2c1.

[0049] The bidirectional threaded structure has a synchronous opposing adjustment function. When the rotating rod 2c1 rotates in the forward or reverse direction, it can drive the clamping seats 2c2 on both sides to move closer or further away synchronously, realizing stepless fine adjustment of the clamping distance. This ensures that the connecting seat 1a is subjected to uniform force and avoids micro-deformation of the structure caused by single-point compression.

[0050] See Figure 5 and Figure 7 As shown, the clamping seat 2c2 is a three-sided clamping structure. The clamping seat 2c2 and the transverse fixing plate 2a cooperate to form a four-sided clamping structure for clamping the corners of the connecting seat 1a. The lower end face of the clamping seat 2c2 is flush with the upper end face of the transverse fixing plate 2a.

[0051] The four-sided clamping method can wrap and constrain the connecting seat 1a from multiple horizontal directions, which greatly improves the horizontal limiting ability and eliminates the problems of horizontal deviation, slippage and micro-shaking that occur during the operation of the pump body 1. The limiting coverage is relatively wide.

[0052] See Figures 3 to 5 As shown, the clamping seat 2c2 has a vertically opening vertical limiting hole, which is vertically aligned with the positioning hole on the connecting seat 1a; the bearing seat 2a1, the fixing seat 2a2, the rotating rod 2c1, the clamping seat 2c2, the stop 2c3, and the vertical limiting hole together constitute the adjustable clamping seat assembly 2c.

[0053] Vertical locking can be achieved by assembling limit bolts through the vertical alignment holes, which restricts the vertical relative movement between the connecting seat 1a and the clamping seat 2c2. Together with the horizontal clamping structure, a three-dimensional limiting system is formed, which further improves the overall anti-deviation effect.

[0054] See Figure 3 and Figure 8 As shown, the stop 2c3 is a stop nut, which is threadedly connected to the rotating rod 2c1. One end face of the stop nut can fit against the outer wall of the fixed seat 2a2.

[0055] The stop nut can be locked and positioned after the clamping distance is adjusted, limiting the rotation of the rotating rod 2c1, preventing the thread from loosening due to long-term vibration of the equipment, ensuring that the clamping state remains stable for a long time, and avoiding clamping failure caused by working condition disturbances.

[0056] See Figure 3 and Figure 8As shown, one end of the rotating rod 2c1 extends outward from the bearing seat 2a1 to form an operating rotating part.

[0057] The rotating part is designed so that operators can directly turn the rotating rod 2c1 with tools to make fine adjustments to the clamping distance without disassembling other components, making assembly, maintenance and adjustment operations convenient and efficient.

[0058] See Figures 5 to 7 As shown, the bottom of the clamping seat 2c2 extends downward to form a guide portion, and a guide groove is provided on the transverse fixing plate 2a along the axial direction of the rotating rod 2c1. The guide portion is slidably assembled in the guide groove.

[0059] The aforementioned guide part, in conjunction with the guide groove, restricts the rotational freedom of the clamping seat 2c2, ensuring that the clamping seat 2c2 can only slide smoothly along the axial direction. This effectively avoids problems such as tilting, jamming, and offset during the clamping process, ensuring smooth clamping and adjustment and high structural fit accuracy.

[0060] In summary, during assembly and use, the split mounting base 2 is first placed in the preset position on the mounting base. The opening angle and locking position of the two-section folding arm 2a3 are adjusted according to the distribution of holes on the base. The horizontal fixing plate 2a and the two-section folding arm 2a3 are locked and fixed on the base using locking bolts and buffer pads 3, thus completing the installation and positioning of the bottom support structure.

[0061] Then, the connecting seat 1a at the bottom of the seawater pump is placed between the two sets of transverse fixing plates 2a. By rotating the exposed operating rotating part of the rotating rod 2c1, the clamping seats 2c2 on both sides are driven to slide synchronously towards each other, so that the clamping seats 2c2 fit and wrap around the corners of the connecting seat 1a, achieving four-sided clamping. After the clamping position is adjusted to the correct position, the stop pieces 2c3 on both sides are tightened to lock the rotating rod 2c1 and fix the current clamping distance.

[0062] Finally, the limiting bolt is passed through the vertical limiting hole of the clamping seat 2c2 and the positioning hole of the connecting seat 1a from top to bottom to complete the vertical locking assembly, so that the pump body 1 forms a reliable constraint in the horizontal, vertical and circumferential directions.

[0063] During actual operation, the alternating loads generated by the impact of sea waves and the turbulence of the ship are absorbed and dissipated by the buffer component 2b and the buffer pad 3, reducing the transmission of vibration to the pump body 1 and minimizing the risk of bolt fatigue and loosening. Simultaneously, the adjustable four-sided clamping structure, the vertical locking structure, and the multi-point circumferential locking structure work together to form a highly redundant, multi-dimensional anti-deviation limiting system. This system evenly distributes the force at each locking point, avoiding localized stress concentration and significantly improving the installation stability and operational reliability of the seawater pump under complex impact conditions at sea.

[0064] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
