Description

Technical Field

[0001] This invention relates to the field of marine engineering equipment, and in particular to a high-efficiency pumping equipment that utilizes marine environmental energy. Background Technology

[0002] Tidal power generation utilizes the potential or kinetic energy generated by the periodic rise and fall of seawater to drive a generator through a water turbine. Potential energy generation primarily employs the method of constructing dams across the sea, while kinetic energy generation utilizes the water flow caused by tides to directly drive an underwater turbine. Both methods suffer from drawbacks such as high investment costs, limitations imposed by the marine environment, and low power generation efficiency.

[0003] Chinese document CN103867421A discloses a modular flexible telescopic cylinder marine tidal pumping device. This device can pump seawater to a higher reservoir during low tide and then generate electricity. However, this pumping device can only operate during low tide and cannot operate during high tide, resulting in low efficiency. Moreover, since there is only one tide per day, even if pumping could be performed during both high and low tides, the efficiency would still be insufficient. Summary of the Invention

[0004] In view of this, it is necessary to provide a high-efficiency pumping equipment that can not only utilize both high and low tides for pumping operations, but also utilize a marine environmental energy conversion mechanism to form a high-pressure gas storage, control the upward and downward movement of the buoy, and achieve all-weather pumping operations by utilizing marine environmental energy.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a high-efficiency water pumping device utilizing marine environmental energy, comprising: A high-pressure gas supply assembly includes a marine environmental energy conversion mechanism, an air compressor, and a high-pressure gas storage tank. The marine environmental energy conversion mechanism collects marine environmental energy and converts it into energy to drive the air compressor. The air compressor compresses air and stores it in the high-pressure gas storage tank. Guide post, the bottom end of which is connected to the seabed foundation; The middle float is slidably connected to the guide column. The bottom of the middle float has at least one inlet / outlet hole, and an electrically controlled inlet / outlet valve is installed in the inlet / outlet hole. The top of the middle float has a high-pressure air inlet hole and an exhaust hole. Both the high-pressure air inlet hole and the exhaust hole are equipped with electrically controlled valves. The high-pressure air inlet hole is connected to the outlet of the high-pressure air storage tank. When the electrically controlled valve of the high-pressure air inlet hole is opened, high-pressure gas enters the middle float. The upper telescopic cylinder has its bottom fixedly connected to the top of the middle float and its top fixedly connected to the upper part of the guide column. The upper telescopic cylinder has a first water inlet hole and a one-way valve that allows water to flow in but not out is installed in the first water inlet hole. The top of the upper telescopic cylinder has a first water supply pipe and a one-way valve that allows water to flow out but not in is installed on the first water supply pipe. The lower telescopic cylinder is fixedly installed at its bottom and its top is fixedly connected to the bottom of the middle float. The lower telescopic cylinder has a second water inlet hole, and a one-way valve that allows water to flow in but not out is installed in the second water inlet hole. The bottom of the lower telescopic cylinder has a second water supply pipe, and a one-way valve that allows water to flow out but not in is installed on the second water supply pipe.

[0006] Furthermore, the marine environmental energy conversion mechanism is one or more of the following: wind energy conversion mechanism, solar energy conversion mechanism, tidal energy conversion mechanism, and wave energy conversion mechanism.

[0007] Furthermore, it also includes a base, which is fixedly connected to the seabed foundation, and the guide post is fixedly connected to the base.

[0008] Furthermore, the top of the upper telescopic cylinder is connected to a first fixed cylinder, and the first water supply pipe is disposed in the first fixed cylinder; the bottom of the upper telescopic cylinder is connected to a second fixed cylinder, and the bottom of the upper telescopic cylinder is fixedly connected to the top of the middle float through the second fixed cylinder.

[0009] Furthermore, a third fixed cylinder is connected to the top of the lower telescopic cylinder, and the top of the lower telescopic cylinder is fixedly connected to the bottom of the middle float via the third fixed cylinder; a fourth fixed cylinder is connected to the bottom of the lower telescopic cylinder, the second water inlet pipe is disposed in the fourth fixed cylinder, and the bottom of the lower telescopic cylinder is fixedly connected to the base via the fourth fixed cylinder.

[0010] Furthermore, it also includes a main water supply pipe, which is connected to the first water supply pipe and the second water supply pipe respectively.

[0011] Furthermore, a main water supply valve is installed on the main water supply pipe.

[0012] Furthermore, a top plate is fixedly connected to the upper part of the guide post, and the first fixing cylinder is fixedly connected to the top plate.

[0013] Furthermore, brackets for supporting the telescopic cylinders are fixedly connected to the outer walls of both the upper and lower telescopic cylinders, and the brackets are slidably connected to the guide post.

[0014] Furthermore, the first water inlet is connected to a water inlet pipe, the inlet of which is located outside the bottom of the middle buoy and is always submerged in seawater.

[0015] Furthermore, when high-pressure gas enters and exits, the central buoy can be completely submerged in water to perform upward and downward operations.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This device utilizes the difference in tidal energy between high and low tides. By controlling the buoyant tank to draw in water at high levels (increasing gravity) and discharge water at low levels (reducing gravity) under different tidal conditions (changes in sea level) in the sea area, the device propels the buoyant tank to move up and down within the range defined by the guide column. This effectively improves the utilization rate of tidal energy, allowing pumping operations to be performed during both high and low tides. This device is also equipped with a marine environmental energy conversion mechanism, which can fully utilize wind, solar, tidal, and wave energy in the marine environment. This energy is converted by an air compressor and stored in a high-pressure gas tank. The high-pressure gas is then controlled to enter the floating buoy in the water at appropriate times. By controlling the air intake (water pressurization) and exhaust (water intake) processes, the amount of water stored in the floating buoy is adjusted to change the balance between gravity and buoyancy in the water, thus altering the magnitude of the gravity-buoyancy difference. This propels the floating buoy to move upwards and downwards within a certain range on the equipment guide column, accelerating its upward and downward speeds. This, in turn, regulates the high-pressure gas generated by the marine environmental energy conversion, adjusting the upward and downward operating frequency of the floating buoy, thereby achieving high-frequency, high-efficiency water pumping. This device not only utilizes ocean tidal energy variations (high and low tides) for pumping operations, but also leverages energy generated by the marine environment (tidal energy, wave energy, wind energy, and solar energy) to efficiently and continuously pump water to higher levels. It intelligently integrates the changes in ocean tidal range and marine conditions, adjusting the pumping operation by switching the buoy's high-pressure discharge and intake states in real time, increasing the frequency of the buoy's ascent and descent, and significantly improving pumping efficiency. This equipment is low-cost to manufacture and easy to install and maintain.

Detailed Implementation

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] like Figure 1 As shown, a high-efficiency water pumping device utilizing marine environmental energy includes: a high-pressure gas supply assembly (not shown in the figure), a base 23, a guide column 7, a central float 20, an inlet water main 12, an upper telescopic cylinder 8, and a lower telescopic cylinder 22.

[0022] The high-pressure gas supply assembly includes a marine environmental energy conversion mechanism, an air compressor, and a high-pressure gas storage tank. The marine environmental energy conversion mechanism collects marine environmental energy and converts it into energy to drive the air compressor. The air compressor compresses the air and stores it in the high-pressure gas storage tank. Marine environmental energy conversion mechanisms can be one or more of the following: wind energy conversion mechanisms, solar energy conversion mechanisms, tidal energy conversion mechanisms, and wave energy conversion mechanisms. Wind energy conversion mechanisms, solar energy conversion mechanisms, tidal energy conversion mechanisms, and wave energy conversion mechanisms can all utilize existing mature products. For example, wind energy conversion mechanisms use existing mature wind turbines, utilizing their impellers to convert wind energy and then directly drive an air compressor through their built-in transmission system; solar energy conversion mechanisms use solar panels to generate electricity, which drives the air compressor; tidal energy conversion mechanisms convert tidal energy into compressed air energy or electrical energy to drive the air compressor; wave energy conversion mechanisms, such as various wave energy devices (oscillating water column type, pendulum type, raft type, etc.), capture mechanical energy and convert it into compressed air energy or electrical energy to drive the air compressor.

[0023] The base 23 is fixedly connected to the seabed foundation 1. There are multiple guide posts 7, which are fixedly connected to the base 23. The top plate 9 is fixedly connected to the top of the guide post 7.

[0024] The middle float 20 is a hollow, sealed float structure. The middle float 20 is slidably connected to the guide post 7. The bottom of the middle float 20 has at least one inlet and outlet hole, and an electrically controlled inlet and outlet valve 5 is installed in the inlet and outlet hole. The top of the middle float 20 has a high-pressure air inlet hole and an exhaust hole. An electrically controlled valve 19a is installed on the high-pressure air inlet hole, and an electrically controlled valve 19b is also installed on the exhaust hole. The high-pressure air inlet hole is connected to the outlet of the high-pressure air storage tank.

[0025] The top of the upper telescopic cylinder 8 is connected to a first fixed cylinder 15, and the bottom of the upper telescopic cylinder 8 is connected to a second fixed cylinder 6; the first fixed cylinder 15 is fixedly connected to the top plate 9, and the second fixed cylinder 6 is fixedly connected to the top of the middle float 20; the first fixed cylinder 15 has a first water inlet pipe 10, and the second fixed cylinder 6 has a first water inlet hole; the first water inlet pipe 10 has a one-way valve 11 that only allows water to flow out and not in, and the first water inlet hole has a one-way valve 17 that only allows water to flow in and not out.

[0026] The top of the lower telescopic cylinder 22 is connected to the third fixed cylinder 4, and the bottom of the lower telescopic cylinder 22 is connected to the fourth fixed cylinder 2; the third fixed cylinder 4 is fixedly connected to the bottom of the middle float 20, and the fourth fixed cylinder 2 is fixedly connected to the base 23; the third fixed cylinder 4 has a second water inlet hole, and the fourth fixed cylinder 2 has a second water supply pipe 16; the second water supply pipe 16 has a one-way valve 14 that only allows water to flow out and not in, and the second water inlet hole has a one-way valve 21 that only allows water to flow in and not out.

[0027] The main water supply pipe 12 is connected to the first water supply pipe 10 and the second water supply pipe 16 respectively, and the main water supply pipe 12 is equipped with a main water supply electric control valve 13.

[0028] In this embodiment, brackets 3 for supporting the telescopic cylinders are fixedly connected to the outer side walls of both the upper telescopic cylinder 8 and the lower telescopic cylinder 22, and the brackets 3 are slidably connected to the guide post 7.

[0029] To ensure that the upper telescopic cylinder 8 can take in water when it is extended, the first water inlet is connected to a water inlet pipe 18. The inlet of the water inlet pipe 18 is located outside the bottom of the middle float 20 and is always submerged in seawater.

[0030] This water pumping equipment shall be operated according to the following steps: 1. Downward movement: When the middle buoy 20 is in seawater and above the guide column, the electrically controlled valve 19b of the vent hole at the top of the middle buoy 20 is opened, and the high-pressure gas inside the middle buoy 20 is discharged. Then, the electrically controlled inlet and outlet valve 5 of the middle buoy 20 is opened, and water is injected into the middle buoy 20 through the inlet and outlet holes. When the weight of the middle buoy 20 is greater than the buoyancy it bears, and the downward movement conditions are met (i.e., sufficient pressure can be applied to the lower telescopic cylinder 22 to force it to compress), the electrically controlled inlet and outlet valves are opened. When the water valve 5 and the electrically controlled valve 19b of the vent are closed, the middle float 20 descends along the guide post 7 due to the weight of the middle float 20 being greater than the buoyancy it bears. This puts pressure on the lower telescopic cylinder 22, compressing it and increasing the water pressure inside. The water inside the lower telescopic cylinder 22 is then discharged from the second water inlet pipe. The descent of the middle float 20 pulls the upper telescopic cylinder 8, causing it to be stretched. This creates a negative pressure inside the cylinder and draws seawater into it from the water inlet pipe 18.

[0031] 2. Low-level air intake and drainage: When the middle float 20 is in seawater and below the guide column, the electrically controlled air intake and drainage valve 5 of the middle float 20 is opened, and the electrically controlled valve 19a of the high-pressure air intake port at the top of the middle float 20 is opened. High-pressure gas is injected into the middle float 20 through the high-pressure air tank, and the middle float 20 drains water. During this process, the middle float 20 drains water at a low level (reducing gravity). When the buoyancy of the middle float 20 is greater than its weight, and the upward condition is met (i.e., sufficient buoyancy can be applied to the upper telescopic cylinder 8 to force the upper telescopic cylinder 8 to be compressed), the electrically controlled air intake and drainage valve 5 and the electrically controlled valve 19a of the high-pressure air intake port are closed.

[0032] 3. Ascending: During the ascending process, since the buoyancy of the middle float 20 is greater than the gravity, the middle float 20 rises along the guide column 7, which in turn puts pressure on the upper telescopic cylinder 8. The upper telescopic cylinder 8 is compressed, and the water pressure inside the upper telescopic cylinder 8 increases. The water inside the upper telescopic cylinder 8 is discharged from the first water inlet pipe 10. The rising of the middle float 20 pulls the lower telescopic cylinder 22, causing the lower telescopic cylinder 22 to be stretched. A negative pressure is formed inside it, and seawater is drawn into the lower telescopic cylinder 22 from the second water inlet.

[0033] 4. High-level venting and water intake: When the middle float 20 rises to the top of the guide column, the electrically controlled valve of the vent hole at the top of the middle float 20 is opened, and the high-pressure gas inside the middle float 20 is discharged. Then, the electrically controlled water inlet and outlet valve 5 of the middle float 20 is opened, and water is injected into the middle float 20 through the water inlet and outlet holes. When the weight of the middle float 20 is greater than the buoyancy it bears, and the descent conditions are met (i.e., sufficient pressure can be applied to the lower telescopic cylinder 22 to force the lower telescopic cylinder 22 to compress), the electrically controlled water inlet and outlet valve 5 and the vent hole are closed, and the middle float 20 enters the descent. This cycle is repeated.

[0034] This equipment utilizes the marine environment (tidal energy, wind energy, wave energy, solar energy, etc.) to generate high-pressure gas, which is stored in a high-pressure gas tank. The high-pressure gas is controlled to enter the floating buoy in the water at appropriate times. By controlling the air intake (water pressure) and air exhaust (water intake) processes, the amount of water stored in the floating buoy is adjusted to change the balance between gravity and buoyancy of the floating buoy in the water, thereby changing the magnitude of the difference between gravity and buoyancy and propelling the floating buoy to move upward and downward within a certain range on the guide column.

[0035] By adjusting the opening and closing of each electrically controlled valve in a timely manner, the water volume in the float is regulated, thereby controlling the relationship between the float's weight and buoyancy during operation, and thus controlling the float's upward and downward movement. When the weight of the float is greater than the buoyancy (and the condition for downward force is met), positive pressure is formed inside the lower telescopic cylinder 22 (drainage), and negative pressure is formed inside the upper telescopic cylinder 8 (water intake); 2) When the buoyancy of the float is greater than the weight (and the condition for upward force is met), positive pressure is formed inside the upper telescopic cylinder 8 (drainage), and negative pressure is formed inside the lower telescopic cylinder 22 (water intake). When the upper and lower telescopic cylinders 8 and 22 are under pressure, the high-pressure water discharged by each is discharged through their respective water supply pipes and then collected into the main water supply pipe 12. The main water supply pipe 12 is equipped with a main water supply valve 14. When the main water supply valve 14 is opened, the water pumped by the equipment will be continuously sent to higher places during the ocean tidal changes (high tide and low tide) to meet the needs of high-level water delivery (seawater aquaculture) and high-level reservoir power generation for hydroelectric power generation. It can also meet the needs of seawater desalination through the high-pressure seawater conditions.

[0036] This pumping equipment can operate using ocean tidal changes or independently of tidal energy. High-pressure gas is used to continuously regulate the inflow and outflow (due to gravity changes) within the buoyancy chamber, accelerating its descent and ascent. This regulates the high-pressure gas generated from the conversion of marine environmental energy, adjusting the buoyancy chamber's up-and-down operating frequency to further improve pumping efficiency. The buoyancy chamber can operate fully submerged. High-pressure gas can be introduced into the sealed chamber to control the water pressure, thereby regulating the combined force of gravity and buoyancy to control its ascent and descent. This, in turn, drives the upper and lower telescopic cylinders to compress and extend, achieving high-frequency, high-efficiency pumping.

[0037] In this embodiment, to facilitate fixing the pumping equipment to the seabed foundation, a base is installed on the seabed foundation. Alternatively, a large floating platform can be used instead of a base to achieve mobile installation.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
