Description

Technical Field

[0001] The present invention relates to the technical field of water intake equipment, and in particular to an anti-scouring and anti-biological type water intake head for seawater. Background Art

[0002] An intake head is a facility located at the bottom of a submerged or semi-submerged river, drawing water into an inlet pipe through its inlet hole. It can also be installed on the seabed of shallow oceans to draw seawater. However, compared to freshwater, the ocean contains more biological populations, so the internal structure of the intake head is more susceptible to biological adhesion and clogging. Furthermore, the high construction costs of seawater intake structures make maintenance and management difficult. Therefore, the present invention proposes an intake head that effectively prevents biological adhesion and clogging.

[0006] As a further improvement of the present invention, the driving member is a cylinder with an outer wall covered with threads, one end of the driving member is hinged to the top cover, and the other end passes through the filter rack and is hinged to the support frame fixedly installed inside the support cylinder; the support frame is an internal hollow structure; the elastic member is arranged between the filter rack and the support frame, and is sleeved on the outer periphery of the driving member.

[0007] As a further improvement of the present invention, the dirt-repelling mechanism also includes a limiting rod, a one-way bearing and a threaded sleeve; two symmetrical limiting grooves are provided on the edge of the filter frame, and two limiting rods are provided on the inner wall of the corresponding support cylinder; a one-way bearing is provided in the center of the filter frame, and a threaded sleeve is fixedly installed on the inner ring of the one-way bearing.

[0008] As a further improvement of the present invention, the dirt ejecting mechanism further includes a power mechanism for driving the driving member to rotate. The power mechanism is provided with a connecting shaft and a worm wheel fan blade. The worm wheel fan blade is movably connected to one end of the connecting shaft, and the other end of the connecting shaft is movably connected to one side of the support frame close to the sealed end of the support cylinder.

[0009] As a further improvement of the present invention, the dirt ejecting mechanism further includes a transmission mechanism arranged inside the support frame, including a driving gear, a driven gear, a complete transmission gear, and a missing transmission gear; the driving gear is coaxially connected to the connecting shaft, the driven gear is coaxially connected to the threaded rod, the complete transmission gear is in tooth engagement with the driving gear, the missing transmission gear is in tooth engagement with the driven gear, and the complete transmission gear is coaxially connected to the missing transmission gear.

[0010] As a further improvement of the present invention, the dirt pushing mechanism includes a mounting frame, a fixed shaft, a connecting bar, a transmission shaft, a dirt pushing plate, and a transmission belt; there are four mounting frames, all arranged on the top cover and evenly distributed around the threaded rod; a fixed shaft is arranged on the mounting frame, and a transmission shaft is arranged on the dirt pushing plate; the connecting bar is non-bendable, and both ends are respectively hinged to the fixed shaft and the transmission shaft; transmission wheels are coaxially connected to both the fixed shaft and the transmission shaft, and the transmission belt is movably sleeved on the transmission wheels on the fixed shaft and the transmission shaft.

[0011] As a further improvement of the present invention, a limiting block is arranged at the position of the mounting frame facing the filter screen frame, and at the same time, the limiting block is arranged at the position of the mounting frame close to the driving member.

[0015] The beneficial effects of the present invention are embodied in:

[0016] Utilize the power generated by the water flow to cause the driving member to rotate intermittently. During the rotation of the driving member, it causes the filter screen frame to move towards the sealed end of the support cylinder and compress the elastic member; when the driving member stops rotating, the elastic member releases its elastic force, driving the filter screen frame to move towards the end cover direction; under the action of the filter screen frame moving towards the end cover direction, the sewage pushing plate moves from the center of the filter screen frame towards the outside. In this way, the dirt accumulated or attached inside the filter screen frame and the support cylinder is pushed out of the support cylinder, reducing the accumulation of dirt or the attachment of organisms inside the filter screen frame and the support cylinder. At the same time, it will also drive the water flow inside the support cylinder, further promoting the discharge of dirt, thus effectively ensuring the normal use of the water intake head; and without using electricity, it reduces the load of the water intake head and lowers the frequency and cost of maintaining the water intake head.

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0027] As Figures 1 to 7 shown, an anti-impact and anti-biological seawater intake head provided by an embodiment of the present invention includes: a device body, and a dirt-removing mechanism 5 and a dirt-pushing mechanism 6 provided inside the device body.

[0028] Specifically, as Figure 1 shown, the device body includes a support cylinder 1, a top cover 3, a railing 2 and a water intake pipe 4; the support cylinder 1 has a sealed structure at one end, and the top cover 3 is arranged at the non-sealed end of the support cylinder 1; a plurality of railings 2 are arranged, evenly distributed between the top cover 3 and the support cylinder 1, and both ends are respectively connected to the mouth of the support cylinder 1 and the edge of the top cover 3; the water intake pipe 4 is arranged on the side wall of the non-sealed end of the support cylinder 1 and is communicated with the inside of the support cylinder 1.

[0029] It should be noted that in order to realize the filtering effect of the intake head on organisms or particulate matter in water, an intercepting structure needs to be arranged at the water intake pipe 4. The intercepting structure formed between the support cylinder 1 and the top cover 3 through the railing 2 can intercept larger organisms or substances in the water and prevent them from entering the water intake pipe 4.

[0030] Specifically, as Figure 2 and Figure 3 shown, the dirt-removing mechanism 5 includes: a filter mesh frame 11, a limiting rod 10 and a support frame 7; the filter mesh frame 11 is slidably installed inside the support cylinder 1 and is densely provided with a plurality of small holes for filtering smaller substances; two symmetrical limiting grooves are arranged at the edge of the filter mesh frame 11, and two limiting rods 10 are arranged on the inner part of the corresponding support cylinder, so that the filter mesh frame 11 will not tilt during the sliding process, avoiding the filter mesh frame 11 from tilting and causing the filtered matter to enter the water intake pipe 4; the filter mesh frame 11 is fixedly installed at a position close to the sealed end inside the support cylinder 1, so that the position of the filter mesh frame 11 inside the support cylinder 1 will not be lower than the position of the mouth of the water intake pipe 4.

[0031] It should be noted that the filter screen frame 11 with densely distributed small holes filters small organisms and substances in water, preventing them from entering the water intake pipe network. If small organisms are not cleaned for a long time, they will accumulate or adhere to the internal structure of the water intake head. Long-term accumulation will cause blockage, resulting in poor water intake. If the filter screen can slide within the support cylinder 1, the accumulated or adhered substances can be scraped off by the filter screen frame 11 and pushed outside the water intake head. If the filter screen tilts within the support cylinder 1 or its position within the support cylinder 1 is lower than the position of the water intake pipe 4 opening, its filtering function will be lost. Therefore, a limiting rod 10 and a support frame 7 are provided to limit the filter screen frame 11.

[0032] Furthermore, as Figure 2 and Figure 3 shown, the dirt ejecting mechanism 5 further includes: a threaded rod 9, a spring 14, a one-way bearing 12, and a threaded sleeve 13; the one-way bearing 12 is arranged at the central position of the filter screen frame 11, and a threaded sleeve 13 is arranged on the inner ring of the one-way bearing 12; one end of the threaded rod 9 is hinged to the middle of the top cover 3, and the other end passes through the threaded sleeve 13 and is hinged to the inside of the support frame 7; the spring 14 is arranged between the filter screen frame 11 and the support frame 7 and is sleeved around the threaded rod 9; by rotating the threaded rod 9 in one direction, the filter screen frame 11 is driven to move towards the sealed end of the support cylinder 1, and by releasing the elastic force of the spring 14 with accumulated pressure, the filter screen frame 11 is driven to move towards the end cover direction.

[0033] It should be noted that when the threaded rod 9 rotates in one direction, if the threaded sleeve 13 cannot rotate, it can move on the rotating threaded rod 9, and in this way, the filter screen frame 11 is driven to move inside the support cylinder 1; when the threaded rod 9 does not rotate or rotates in the reverse direction, under the above preconditions, to make the filter screen frame 11 movable inside the support cylinder 1, the threaded sleeve 13 needs to be rotatable, but the filter screen frame 11 cannot rotate. The above problem can be solved by arranging a one-way bearing 12 between the filter screen frame 11 and the threaded sleeve 13.

[0034] Furthermore, as Figure 2 shown, the dirt ejecting mechanism 5 further includes a power mechanism 8 for driving the threaded rod 9 to rotate. The power mechanism 8 includes a connecting shaft 15 and a turbine fan blade 16. The turbine fan blade is movably connected to one end of the connecting shaft 15, and the other end of the connecting shaft 15 is movably connected to one side of the support frame 7 close to the sealed end of the support cylinder; the water flow will drive the turbine fan blade 16 to rotate, and by the rotation of the turbine fan blade 16, the threaded rod 9 is driven to rotate.

[0035] It should be noted that if the threaded rod 9 is driven to rotate by electricity, it is necessary to build a power supply line or add a storage battery. Moreover, building a power supply line and adding a storage battery underwater are costly and difficult to maintain. However, water flow will be generated when water enters the water intake pipe 4 from the support cylinder 1, and the turbine blade will rotate under the impact of the water flow, and the threaded rod 9 is driven to rotate by the rotation of the turbine blade.

[0036] Furthermore, as Figure 4 shown, the dirt ejecting mechanism 5 further includes a transmission mechanism arranged inside the support frame 7, including a driving gear 17, a driven gear 18, a complete transmission gear 21 and an incomplete transmission gear 20; the driving gear 17 is coaxially connected with the connecting shaft 15, the driven gear 18 is coaxially connected with the threaded rod 9, the complete transmission gear 21 is in tooth engagement with the driving gear 17, the incomplete transmission gear 20 is in tooth engagement with the driven gear 18, and the complete transmission gear 21 is coaxially connected with the incomplete transmission gear 20. When the turbine blade drives the connecting shaft 15 to rotate, it will drive the driving gear 17 to rotate. The rotation of the driving gear 17 will drive the complete transmission gear 21 to rotate. The rotation of the complete driven gear will drive the incomplete transmission gear 20 to rotate. When the incomplete transmission gear 20 rotates, it will drive the driven gear 18 to rotate, and the rotation of the driven gear 18 will drive the threaded rod 9 to rotate; when the toothless block part of the incomplete transmission gear 20 faces the driven gear 18, the threaded rod 9 will stop rotating.

[0037] It should be noted that the turbine fan blade 16 can only rotate in one direction under the drive of water flow. Since the filter screen frame 11 needs to slide inside the support cylinder 1, there must be a moment when the threaded rod 9 stops rotating; the existence of the incomplete transmission gear 20 can make the driving force transmitted from the turbine fan blade 16 to the threaded rod 9 have a disconnection moment, and the spring 14 that releases elasticity can cooperate to drive the filter screen frame 11 to move towards the end cover direction.

[0038] Specifically, as Figures 5 to 7 shown, the dirt pushing mechanism 6 includes a mounting frame 22, a fixed shaft 23, a connecting bar 24, a transmission shaft 19, a dirt pushing plate 26 and a transmission belt 27; there are four mounting frames 22, all of which are arranged on the top cover 3 and are evenly distributed around the threaded rod 9; a fixed shaft 23 is arranged on the mounting frame 22, and a transmission shaft 19 is arranged on the dirt pushing plate 26; the connecting bar 24 is not bendable, and both ends are respectively hinged to the fixed shaft 23 and the transmission shaft 19; transmission wheels are coaxially connected to both the fixed shaft 23 and the transmission shaft 19, and the transmission belt 27 is movably sleeved on the transmission wheels on the fixed shaft 23 and the transmission shaft 19. A limiting block is arranged at the position of the mounting frame 22 facing the filter screen frame 11. During the process of the filter screen frame 11 bouncing upwards, it will contact the dirt pushing plate 26. The dirt pushing plate 26 drives the connecting bar 24 to rotate. Due to the arrangement of the transmission belt 27, when the connecting bar 24 rotates, the transmission belt 27 will drive the rotating shaft 25, so that the dirt pushing plate 26 can maintain a horizontal state during the process of moving outwards, and the dirt pushing plate 26 will push the dirt on the filter screen frame 11 towards the outside of the support cylinder 1.

[0039] It should be noted that the non-bendable connecting bar 24 is hinged to the mounting bracket 22 and the sewage pushing plate 26 respectively. The setting of the mounting bracket 22 causes a certain angle between the connecting bar 24 and the axis of the threaded rod 9. When the sewage pushing plate 26 receives the force from the filter screen frame 11 towards the end cover direction, it will move towards the railing 2. When the filter screen moves towards the support frame 7, the connecting bar 24 moves closer to the threaded rod 9 under the gravity of the sewage pushing plate 26, so that the sewage pushing plate 26 returns to its original position. In the above process, in order to prevent the sewage pushing plate 26 from flipping during the movement, the design of the transmission belt 27 and the transmission wheel can ensure that the sewage pushing plate 26 always remains in a horizontal state during the movement.

[0040] In addition, for the convenience of understanding the anti-impact and anti-biological seawater intake head, its working principle and usage process are introduced as follows:

[0041] During the process of the intake head extracting seawater, the seawater flows into the interior of the support cylinder 1 through the railing 2 and is pumped out through the water intake pipe 4. The railing 2 will isolate the larger organisms in the seawater outside the support cylinder 1. At the same time, the seawater flow will drive the turbine fan blade 16, and the turbine fan blade 16 will drive the connecting shaft 15 to rotate. The driving gear 17 on the connecting shaft 15 drives the transmission shaft 19 to rotate through the transmission full gear 21, so that the transmission missing gear 20 on the transmission shaft 19 rotates simultaneously. The part with teeth on the transmission missing gear 20 contacts the driven gear 18 and drives the driven gear 18 to rotate. The driven gear 18 drives the threaded rod 9 to rotate. At this time, the one-way bearing 12 cannot rotate on the filter screen frame 11, which also makes the threaded sleeve 13 unable to rotate. Under the limitation of the limiting rod 10, the threaded rod 9 drives the filter screen frame 11 to move downward through the threaded sleeve 13. When the filter screen frame 11 moves to the bottom position of the threaded rod 9, the part without teeth on the transmission missing gear 20 will rotate to the position of the driven gear 18, so that the threaded rod 9 stops rotating. The spring 14 will give an upward force to the filter screen frame 11. At this time, the one-way bearing 12 can rotate and will drive the threaded sleeve 13 to rotate together. The filter screen frame 11 and the deposited dirt are bounced upward. And during the process of the filter screen frame 11 bouncing upward, it will contact the sewage pushing plate 26. The sewage pushing plate 26 drives the connecting bar 24 to rotate. And due to the setting of the transmission belt 27, during the rotation of the connecting bar 24, the transmission belt 27 will drive the rotating shaft 25, so that the sewage pushing plate 26 can remain in a horizontal state during the outward movement. The sewage pushing plate 26 will push the dirt on the filter screen frame 11 towards the outside of the support cylinder 1, so as to ensure that the dirt inside the filter screen frame 11 and the support cylinder 1 is better cleaned out.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
