Description
Technical Field
[0001] The utility model relates to the technical field of seawater pumps, in particular to an emergency seawater pump for intelligent water regulation for sea surface fire fighting. Background Art
[0002] A seawater pump is a device specially used for extracting, transporting and treating seawater. It plays an important role in the fields of marine engineering, shipbuilding industry, marine scientific research, etc. The basic function of a seawater pump is to extract seawater from the ocean or seawater storage facilities, and then go through a series of treatment processes so that the seawater can meet the needs of different fields, such as seawater desalination, cooling systems, marine aquaculture, etc.
[0003] The emergency seawater pump for intelligent water diversion for sea surface fire fighting is a kind of equipment specially designed for marine fire rescue. It can quickly extract seawater in an emergency to provide water for firefighting vessels or onshore facilities. This type of pump usually has efficient drainage capacity, good corrosion resistance and high mobility, and can adapt to the complex and changeable marine environment.
[0004] When existing seawater pumps are pumping seawater, the direct impact of the water flow may cause the impeller to vibrate, affecting the stability and life of the pump. Due to the lack of an effective buffering mechanism, the impeller of a conventional seawater pump may produce unnecessary vibrations due to the impact of the water flow, thereby affecting the overall performance of the pump. Utility Model Content
[0005] In view of the above-mentioned problems, the utility model discloses an emergency seawater pump for intelligent water diversion for sea surface fire fighting.
[0006] The technical solution of the utility model is: an emergency seawater pump for intelligent water diversion for sea surface fire fighting, comprising a seawater pump body with a water inlet pipe and a water outlet pipe provided on the side wall, and a flow stabilizing filter provided at the water inlet pipe, wherein an impeller facing the water inlet pipe is provided in the seawater pump body;
[0007] The steady flow filter includes a plurality of sliding grooves arranged along the circumferential direction on the inner wall of the water inlet pipe, a filter mesh plate slidably connected to the sliding grooves in a one-to-one correspondence through sliding blocks, a fixed mounting ring slidably connected to the sliding grooves in a one-to-one correspondence through fixed blocks, and an elastic rod arranged between the fixed blocks and the corresponding sliding blocks.
[0008] Furthermore, the filter screen plate includes an annular main plate slidably connected to the sliding groove in a one-to-one correspondence through a sliding block, a filter body arranged at the bottom end of the annular main plate, and a plurality of adjustment screen plates hinged to the side wall of the filter body along the circumferential direction.
[0009] Description: When the filter screen is filtering the seawater entering the main body of the seawater pump, the impact of the seawater on the filter screen compresses the elastic rod, causing the sliding block to move in the corresponding sliding groove to the side close to the fixed block. At this time, the buffering effect of the elastic rod can reduce the impact force of the seawater flow entering the main body of the seawater pump, ensuring that the impeller can rotate more stably when rotating, avoiding slight shaking of the impeller due to excessive impact force of the water flow, reducing impact force and wear, and ensuring its service life. At the same time, when the water flow impacts the filter screen, in order to ensure the water flow rate of the main body of the seawater pump, the water flow can impact each adjustment screen and make it rotate and open.
[0010] Furthermore, the water outlet pipe is provided with a sealing connector for connecting to an external water pipe, and the sealing connector includes a sealed inner tube whose end can be inserted into the water outlet pipe, a fixed horizontal plate sleeved on the outer wall of the sealed inner tube, a sealed outer tube arranged on both sides of the fixed horizontal plate and located at the periphery of the sealed inner tube, and a sealing ring arranged on the inner wall of the sealed outer tube and the outer wall of the sealed inner tube.
[0011] Description: When the sealing connector is in use, the outlet pipe is inserted between the sealed outer pipe and the sealed inner pipe at the lower end of the fixed horizontal plate, and is sealed by a sealing ring to avoid leakage at the connection, thereby improving the working efficiency of the seawater pump body. When it is necessary to connect to an external water pipe, the external water pipe is inserted between the sealed outer pipe and the sealed inner pipe at the upper end of the fixed horizontal plate, and is sealed by a sealing ring to avoid leakage at the connection, thereby ensuring that the seawater pump can transport liquid with higher efficiency.
[0012] Furthermore, the sealing ring is a detachable structure, and the length between the two sealing rings is the same as the thickness of the water outlet pipe.
[0013] Description: The sealing ring is set as a detachable structure to facilitate maintenance and replacement and ensure reliable sealing. By limiting the relationship between the length between the two sealing rings and the thickness of the water outlet pipe, the water outlet pipe and the two sealing rings are ensured to fit tightly, providing a better sealing effect.
[0014] Furthermore, both upper and lower ends of the fixed horizontal plate are provided with mounting vertical rods, and the side walls of the mounting vertical rods are symmetrically hinged with two arc-shaped fixing plates connected by bolts at the front and rear sides of the sealed outer tube.
[0015] Note: When it is necessary to fix the outlet pipe to the sealed outer pipe and the sealed inner pipe to ensure the reliability of the connection, two relatively distributed arc-shaped fixing plates are buckled on the outside of the sealed outer pipe and fastened with bolts, which enhances the stability and sealing performance of the connection and reduces the maintenance requirements caused by leakage or looseness.
[0016] Beneficial effects of the utility model:
[0017] When the emergency seawater pump of the utility model is in use, solid impurities in the seawater are filtered through the filter screen disk in the steady flow filter. At the same time, the seawater impacts the filter screen body and compresses the elastic rod, so that the filter screen body moves to the side close to the fixed block. At this time, the impact force of the seawater flow entering the seawater pump body can be reduced through the buffering effect of the elastic rod, ensuring that the impeller can rotate more stably when rotating, avoiding slight shaking of the impeller due to excessive impact force of the water flow, reducing impact force and wear, and ensuring its service life. In order to ensure the water flow rate of the seawater pump body, the water flow can impact each adjusting screen and make it rotate and open, and the water outlet pipe and the external water pipe are tightly connected through the sealing connector. At the same time, the sealing ring is used to seal to avoid leakage at the connection, thereby improving the working efficiency of the seawater pump body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] Example 1
[0025] like Figure 1 , 2 As shown, an emergency seawater pump for intelligent water diversion for sea surface fire fighting comprises a seawater pump body 1 with a water inlet pipe 10 and a water outlet pipe 11 on the side wall, a flow stabilizing filter 2 arranged at the water inlet pipe 10, and an impeller 12 directly facing the water inlet pipe 10 is arranged in the seawater pump body 1, wherein the seawater pump body 1 adopts the existing technology;
[0026] The steady flow filter 2 includes four sliding grooves 20 arranged on the inner wall of the water inlet pipe 10 along the circumferential direction, a filter screen plate 22 slidably connected to the sliding grooves 20 in a one-to-one correspondence through a sliding block 220, a fixed mounting ring 23 slidably connected to the sliding grooves 20 in a one-to-one correspondence through a fixed block 230, and an elastic rod 24 arranged between the fixed block 230 and the corresponding sliding block 220;
[0027] The filter screen disc 22 includes an annular main disc 221 slidably connected to the sliding groove 20 by a sliding block 220, a filter body 222 arranged at the bottom end of the annular main disc 221, and four adjustment screens 223 hinged to the side wall of the filter body 222 along the circumferential direction. When the filter screen disc 22 filters the seawater entering the seawater pump body 1, due to the impact of the seawater on the filter body 222, the filter body 222 compresses the elastic rod 24, so that the sliding block 220 moves in the corresponding sliding groove 20 to the side close to the fixed block 230. At this time, the impact force of the seawater flow entering the seawater pump body 1 can be reduced through the buffering effect of the elastic rod 24, ensuring that the impeller 12 can rotate more stably when rotating, avoiding slight shaking of the impeller 12 due to excessive impact force of the water flow, reducing impact force and wear, and ensuring its service life. At the same time, when the water flow impacts the filter screen disc 22, in order to ensure the water flow rate of the seawater pump body 1, the water flow can impact each adjustment screen 223 and rotate it to open.
[0028] Example 2
[0029] The difference between this embodiment and embodiment 1 is that:
[0030] A sealing connector 3 for connecting an external water pipe is provided at the water outlet pipe 11. The sealing connector 3 includes a sealing inner pipe 30 with one end that can be inserted into the water outlet pipe 11, a fixed horizontal plate 31 sleeved on the outer wall of the sealing inner pipe 30, a sealing outer pipe 32 provided on both sides of the fixed horizontal plate 31 and located outside the sealing inner pipe 30, and a sealing ring 33 provided at the inner wall of the sealing outer pipe 32 and the outer wall of the sealing inner pipe 30. When the sealing connector 3 is in use, the water outlet pipe 11 is inserted between the sealing outer pipe 32 and the sealing inner pipe 30 at the lower end of the fixed horizontal plate 31, and is sealed by the sealing ring 33 to avoid leakage at the connection, thereby improving the working efficiency of the seawater pump body 1. When it is necessary to connect with an external water pipe, the external water pipe is inserted between the sealing outer pipe 32 and the sealing inner pipe 30 at the upper end of the fixed horizontal plate 31, and is sealed by the sealing ring 33 to avoid leakage at the connection, thereby ensuring that the seawater pump can transport liquid with higher efficiency.
[0031] The sealing ring 33 is a detachable structure, and the length between the two sealing rings 33 is the same as the thickness of the water outlet pipe 11. The sealing ring 33 is set as a detachable structure to facilitate maintenance and replacement, and ensure reliable sealing. By limiting the relationship between the length between the two sealing rings 33 and the thickness of the water outlet pipe 11, it is ensured that the water outlet pipe 11 and the two sealing rings 33 are closely fitted, providing a better sealing effect;
[0032] The upper and lower ends of the fixed horizontal plate 31 are provided with mounting vertical rods 310, and the side walls of the mounting vertical rods 310 are symmetrically hinged on the front and rear sides of the sealed outer tube 32 with two arc-shaped fixing plates 311 connected by bolts. When it is necessary to fix the water outlet pipe 11 to the sealed outer tube 32 and the sealed inner tube 30 to ensure the reliability of the connection, the two relatively distributed arc-shaped fixing plates 311 are buckled on the outside of the sealed outer tube 32 and fastened by bolts, thereby enhancing the stability of the connection and the sealing performance, and reducing the maintenance requirements caused by leakage or looseness.
[0033] A method for using an emergency seawater pump for intelligent water diversion for sea surface fire fighting in this embodiment includes the following steps:
[0034] S1. Insert the water outlet pipe 11 between the sealed outer pipe 32 and the sealed inner pipe 30 at the lower end of the fixed horizontal plate 31, and seal it with the sealing ring 33. Insert the external water pipe between the sealed outer pipe 32 and the sealed inner pipe 30 at the upper end of the fixed horizontal plate 31, and seal it with the sealing ring 33. At the same time, two relatively distributed arc-shaped fixed plates 311 are buckled on the outside of the sealed outer pipe 32 and fastened with bolts.
[0035] S2. The seawater pump body 1 works. The seawater is pumped into the seawater pump body 1 through the water inlet pipe 10 by the rotation of the impeller 12. When the seawater passes through the water inlet pipe 10, the solid impurities in the seawater are filtered through the filter body 222. At the same time, due to the impact of the seawater on the filter body 222, the filter body 222 compresses the elastic rod 24, so that the sliding block 220 moves in the corresponding sliding groove 20 to the side close to the fixed block 230. At this time, the impact force of the seawater flow entering the seawater pump body 1 can be reduced by the buffering effect of the elastic rod 24, ensuring that the impeller 12 can rotate more stably when rotating;
[0036] S3. When the water flow hits the filter screen 22, in order to ensure the water flow rate of the seawater pump body 1, the water flow can hit each adjustment screen 223 and make it rotate and open. Finally, the seawater pumped into the seawater pump body 1 can be discharged through the outlet pipe 11.
