Description

Technical Field

[0001] This utility model relates to the field of seawater pump maintenance technology, specifically a seawater pump maintenance and transportation tool. Background Technology

[0002] A seawater pump is a special industrial pump used to transport seawater. It is a key piece of equipment in many coastal factories, power plants, ships and marine engineering projects. Due to the special nature of the medium it transports, it differs significantly from ordinary clean water pumps in design, materials and applications. The reason why seawater pumps are special is that they need to deal with seawater. Seawater contains a large amount of chloride ions, which will cause rapid corrosion to ordinary carbon steel and cast iron. Different metal materials inside the pump are prone to forming galvanic cells in the seawater electrolyte, resulting in galvanic corrosion. Seawater contains particulate matter such as silt and suspended solids, which will cause scouring and wear to the flow parts.

[0003] Seawater pumps are far more than simple water conveyance devices; they are high-value assets that integrate corrosion-resistant materials science, precision mechanical design, and high-reliability engineering. In energy hubs, their stable operation is directly related to the security of energy supply. Therefore, from pump manufacturing to installation and maintenance, every step requires extremely high professional standards and a rigorous attitude. However, when existing seawater pumps malfunction and need repair, they are usually lifted by ropes. Seawater pumps are easily affected by sea winds and other factors, making them prone to swinging and impacts, which can damage them. To address this, this utility model proposes a seawater pump maintenance and transportation tool. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the tendency of seawater pumps to swing erratically and be prone to impacts during lifting, which can damage the pumps, this invention proposes a seawater pump maintenance and transportation tool.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a seawater pump maintenance and transfer tooling, including a base plate, a support frame fixedly connected to the base plate, and a lifting and stabilizing structure provided on the support frame;

[0006] The lifting and stabilizing structure includes a fixed plate with an clearance groove. A sleeve is fixedly connected to the inner wall of the fixed plate. A limit piece is slidably connected to the inner wall of the sleeve. A guide rod is fixedly connected to one side of the limit piece. The side of the guide rod is slidably connected to the inner wall of the sleeve. A fixed platform is fixedly connected to one end of the guide rod.

[0007] Preferably, the support frame is divided into upper and lower layers, and the bottom of the fixing plate is slidably connected to the upper layer of the support frame.

[0008] Preferably, the inner wall of the fixed platform is threaded with a threaded rod, one end of which is rotatably connected to a clamping plate via a bearing, and a limit block is fixedly connected to one side of the clamping plate, the limit block being slidably connected to one side of the fixed platform.

[0009] Preferably, a lifting ring is fixedly connected to the top of the fixed platform, and a traction cable is connected to the lifting ring through a hook.

[0010] Preferably, one end of the traction cable is fixedly connected to a reel, and one side of the reel is fixedly connected to a motor, which is fixedly connected to a fixed plate.

[0011] Preferably, a support block is slidably connected to one side of the reel, the bottom of the support block is fixedly connected to the top of the fixing plate, and the traction cable passes through the clearance groove.

[0012] Preferably, the bottom of the base plate is fixedly connected to four sets of movable wheels, and a support plate is fixedly connected to the support frame, with a counterweight on the support plate.

[0013] The advantages of this utility model are:

[0014] This invention features a fixed plate for mounting a sleeve, a sleeve that works with a guide rod inside to stabilize the seawater pump during ascent, a fixed platform for securing the pump with a clamp, and a support frame that allows the lifting and stabilizing structure to slide on its upper layer, enabling the pump to be lifted into its lower layer. The pump can then be lowered onto a base plate and moved via four sets of wheels at the bottom of the base plate. The pump is enclosed within the support frame, further reducing the probability of damage from collisions during transport. A support plate on the support frame, along with a counterweight, maintains stability during pump lifting, further reducing the likelihood of the device tipping over. This design, which ensures stable vertical lifting and protects the pump during subsequent transport, solves the problem of the pump being easily damaged by sea winds and impacts during lifting.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a seawater pump maintenance and transportation tool. (Refer to...) Figure 1 , Figure 3 and Figure 5 A seawater pump maintenance and transfer tool includes a base plate 1, a support frame 2 fixedly connected to the base plate 1, and a lifting and stabilizing structure 3 provided on the support frame 2.

[0025] The stabilizing structure 3 includes a fixed plate 301 with a clearance groove 302. A sleeve 303 is fixedly connected to the inner wall of the fixed plate 301. A limiting piece 304 is slidably connected to the inner wall of the sleeve 303. A guide rod 305 is fixedly connected to one side of the limiting piece 304. The side of the guide rod 305 is slidably connected to the inner wall of the sleeve 303. A fixed platform 306 is fixedly connected to one end of the guide rod 305. When the seawater pump is fixed on the fixed platform 306, the seawater pump can be lifted. During the lifting process, the sleeve 303, in conjunction with the guide rod 305, can maintain the stability of the fixed platform 306, thereby maintaining the stability of the seawater pump, reducing the swaying of the seawater pump, and achieving a protective effect. By setting the limiting piece 304 on the guide rod 305, the guide rod 305 can be prevented from detaching from the sleeve 303.

[0026] Reference Figure 1 and Figure 2 The support frame 2 is divided into upper and lower layers. The bottom of the fixing plate 301 is slidably connected to the upper layer of the support frame 2. By setting up the upper and lower layers of the support frame 2, the upper layer is used for the movement of the fixing plate 301, so that the lifted seawater pump can be brought into the lower support frame 2. The seawater pump is placed on the bottom plate 1 below the support frame 2. The lower layer of the support frame 2 surrounds the seawater pump to protect it during the transfer of the seawater pump and reduce the probability of impact.

[0027] Reference Figure 3 and Figure 4 The inner wall of the fixed platform 306 is threaded with a threaded rod 4. One end of the threaded rod 4 is rotatably connected to a clamping plate 5 via a bearing. A limit block 6 is fixedly connected to one side of the clamping plate 5. The limit block 6 is slidably connected to one side of the fixed platform 306. By rotating the threaded rod 4, the clamping plate 5 rotatably connected to it can be moved. The moving clamping plate 5 can clamp the seawater pump between the clamping plate 5 and the fixed platform 306. The limit block 6 on the clamping plate 5 is used to stabilize the clamping plate 5 and keep it stable during movement to prevent torsion.

[0028] Reference Figure 3 and Figure 4 The top of the fixed platform 306 is fixedly connected to a lifting ring 7. A traction cable 8 is connected to the lifting ring 7 through a hook. By setting the lifting ring 7 and the traction cable 8 to be connected through the hook, the fixed platform 306 and the seawater pump can be lifted by pulling the traction cable 8. After the seawater pump enters the lower layer of the support frame 2, the traction cable 8 can be released to place the seawater pump on the base plate 1.

[0029] Reference Figure 1 and Figure 3One end of the traction cable 8 is fixedly connected to a reel 9, and a motor 10 is fixedly connected to one side of the reel 9. The motor 10 is fixedly connected to the fixed plate 301. By starting the motor 10, the reel 9 connected to the output end of the motor 10 can be driven to rotate. The rotating reel 9 can wind up the traction cable 8, thereby lifting the fixed platform 306 connected to the traction cable 8, and thus lifting the seawater pump.

[0030] Reference Figure 1 and Figure 3 A support block 11 is slidably connected to one side of the reel 9. The bottom of the support block 11 is fixedly connected to the top of the fixed plate 301. The traction cable 8 passes through the clearance groove 302. The support block 11 is used to support the rotation of the reel 9. The support block 11 and the motor 10 can provide two stable support points for the reel 9, which can maintain the stable operation of the reel 9. The clearance groove 302 on the fixed plate 301 is used to avoid the traction cable 8, thus ensuring the operation function of the device.

[0031] Reference Figure 1 The bottom of the base plate 1 is fixedly connected with four sets of movable wheels 12. The support frame 2 is fixedly connected with a support plate 13 and a counterweight 14 is provided on the support plate 13. The movable wheels 12 are used for the transfer of the seawater pump after lifting. The support plate 13 and the counterweight 14 can stabilize the support frame 2, so that the device will not easily tip over when lifting the seawater pump.

[0032] Working principle: In use, first slide the fixing plate 301 on the upper layer of the support frame 2, so that it slides to the farthest end away from the counterweight block 14. Then, start the motor 10 to drive the reel 9, loosen the traction cable 8, and lower the support platform. With the cooperation of the sleeve 303 and the guide rod 305, the trajectory of the fixing platform 306 during the lowering process remains vertical. After the fixing platform 306 covers the outside of the seawater pump, rotate the threaded rod 4 to make the clamping plate 5 clamp the seawater pump. After the seawater pump is fixed, start the motor 10 to reverse, drive the reel 9 to wind the traction cable 8, and pass through... The connection between the traction cable 8 and the fixed platform 306 lifts the fixed platform 306 and the seawater pump. Similarly, the trajectory of the seawater pump remains vertical during the lifting process. After the seawater pump is fully lifted, the fixed plate 301 slides in the opposite direction on the upper layer of the support frame 2 to bring the seawater pump into the lower layer of the support frame 2. Then, the motor 10 is started to lower the seawater pump and place it on the base plate 1. At this time, the seawater pump is covered by the support frame 2, which can provide stable protection during the subsequent transportation of the seawater pump. During the lifting process of the seawater pump, the counterweight 14 provides stable support for the device.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
