Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to an anti-icing device and method based on a photovoltaic protection reservoir water measuring facility. Background Art

[0002] With the increasing popularity of information technology, water conservancy systems are developing towards informatization. Taking the automation of reservoir water measurement facilities as an example, many reservoirs have built automated water measurement facilities. Figure 1 This structure is achieved by vertically fixing a steel tube water level gauge platform on the water-facing side of the reservoir dam, setting up a working platform on the top, and equipping it with equipment such as a rain gauge, lightning rod and solar power supply system.

[0003] However, in applications in western and northern regions, the construction of steel-tube water level gauges presents significant challenges. Due to prolonged freezing periods in winter, the water surface forms cones of ice, which periodically collide with the steel tubes. This causes plastic deformation under repeated bending loads, potentially cracking the internal power supply insulation and dramatically increasing microbending losses in communication cables, leading to larger measurement errors.

[0004] Based on this, it is particularly important to study a device for protecting the periphery of steel pipe columns and preventing them from freezing. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the present invention proposes an anti-icing device and method based on a photovoltaic protection reservoir water measuring facility.

When the lifting assembly drives the piston plate upward, the gas reverse thrust is used to push the buoyancy shell downward, driving the impact ring to impact the water surface. When the lifting assembly drives the piston plate downward, the air cavity draws gas through the one-way air inlet pipe assembly, driving the buoyancy shell and the impact ring to move upward synchronously.

[0007] Preferably, the lifting component includes a base frame, the base frame is in a "C" - shaped structure, and a notch is formed at the top of the base frame; a spiral cam and two guide rods. The spiral cam and the guide rods are both arranged inside the base frame. The two guide rods are respectively fixed on both sides of the spiral cam. The spiral cam is driven to rotate by a rotating motor; a slider, the slider is sleeved on the spiral cam and the two guide rods. A spring is connected between the slider and the base frame, and the spring is respectively sleeved on the guide rods; a convex block, the convex block is connected to both sides of the slider and respectively moves along the spiral groove inside the spiral cam to drive the slider to move up and down; a push rod, the push rod is connected above the slider, and the other end passes through the notch and is connected to the piston plate.

[0008] Preferably, two symmetrically distributed support seats are connected to the lower part of the base frame. The support seats are in an "L" - shaped structure, and reinforcing ribs are arranged on the support seats. The rotating motor is arranged between the two support seats.

[0009] Preferably, a counterweight block is detachably connected to the bottom of the floating shell, and the support seats and the rotating motor are detachably installed above the counterweight block.

[0010] Preferably, the counterweight block is in a conical structure, and a sliding through - hole which forms a clearance fit with the pipe body is arranged at the center of the counterweight block.

[0011] Preferably, a taper ring is fixedly connected to the bottom of the impact ring.

[0012] Preferably, several groups of ice - breaking cones are respectively fixed on the bottom surfaces of the impact ring and the taper ring.

[0013] Preferably, check valves are respectively arranged inside the one - way air outlet pipe group and the one - way air inlet pipe group; the air outlet of the one - way air outlet pipe group is in a frustum - shaped structure with an inward contraction.

[0014] Preferably, photovoltaic panels are arranged on the floating shell, and the photovoltaic panels are electrically connected to the lifting component.

[0015] The present invention also proposes a method for an anti - icing device based on a photovoltaic - protected reservoir water - measuring facility. Using any one of the above - mentioned anti - icing devices based on a photovoltaic - protected reservoir water - measuring facility, it includes the following steps:

[0016] S1, installation and positioning:

[0017] The above - mentioned anti - icing device based on a photovoltaic - protected reservoir water - measuring facility is sleeved on the steel pipe body and can slide along the steel pipe body.

[0018] S2, position calibration:

[0019] Adjust the axial positioning of the floating shell on the steel pipe body to make the whole floating shell immersed in the water body, and the ports of the one - way air outlet pipe group are below the water surface; the ground of the impact ring is kept at a preset distance from the static water surface through a connecting column;

[0020] S3, action execution:

[0021] The lifting assembly drives the piston plate to move upward, and the gas in the air cavity is discharged at high speed through the one-way air outlet pipe assembly;

[0022] At the same time, under the action of negative pressure, the outside of the flexible water bag is filled with water and completely placed in the container cavity, increasing the total weight of the floating shell; the gas reverse thrust pushes the floating shell and the impact ring to move downward along the steel tube body;

[0023] The impact ring hits the water surface, forming water surface waves, and the bubble group discharged by the one-way air outlet group bursts in the water, disturbing the water around the pipe body;

[0024] S4, reset;

[0025] The lifting assembly drives the piston plate downward, and the negative pressure generated in the air cavity draws in external gas through the one-way air inlet assembly. The gas in the container cavity is compressed and filled into the inside of the flexible water bag assembly, and then discharged outside the floating shell to reduce weight. The air cavity is filled with gas to restore the buoyancy state, driving the impact ring to float up along the steel pipe body and return to the initial spacing.

[0026] S5, loop;

[0027] The above steps S3 to S4 are executed cyclically to keep the water around the steel pipe in a dynamic flow state, thereby achieving anti-icing through synergistic effect.

[0028] Compared with the existing technology, the above technical solution has the following advantages or beneficial effects:

[0029] 1. In this invention, the impact ring, one-way air outlet pipe assembly, and flexible water bladder assembly work together through the inflation and exhaust cycles within the buoyancy shell to prevent ice formation around the steel tube. During the exhaust process, the exhausted gas creates a reverse thrust for the buoyancy shell, causing it to move downward along the steel tube, thereby driving the impact ring to strike the water surface and disturb the surrounding water. Simultaneously, after the gas is discharged from the one-way air outlet pipe assembly, it forms a group of buoyant bubbles. When the bubbles burst at the water surface, the shock waves released cause the water surface to oscillate, thereby preventing ice formation around the steel tube.

[0030] 2. In the present invention, the lifting assembly can quickly discharge the gas in the air cavity from the one-way air outlet pipe group through the cooperation between the slider, spring, spiral cam and push rod, thereby increasing the downward thrust of the floating shell, thereby significantly enhancing the impact effect of the impact ring on the water surface, expanding the fluctuation range of the water surface, and achieving anti-icing protection in a wider range around the steel pipe body.

[0031] 3. In the present invention, photovoltaic panels are installed above the steel tube water level gauge and the floating shell. The photovoltaic panels are electrically connected to the lifting assembly, realizing the conversion between solar energy and mechanical energy, so that the lifting assembly obtains a sustainable power supply and reduces the dependence on external energy to a certain extent.

[0046] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0048] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0049] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0050] like Figure 1 As shown, the steel tube water level gauge platform b is fixed on the water-facing surface of the reservoir dam a, with its steel tube body b1 extending vertically downward into the water. The lower part of the steel tube body b1 extends at least 1 meter below the dead water level of the reservoir, and the upper part extends at least 1.5 meters above the maximum historical water level of the reservoir. A working platform b2 is set above the steel tube body b1 to facilitate equipment maintenance. Components such as the rain gauge equipment, lightning rod equipment, and solar power supply equipment b3 are set on the working platform b2.

[0051] However, this structure has certain problems. During winter, when the water surface freezes due to low temperatures, the ice cones will repeatedly impact and contact the steel pipe b1, causing it to bend. This can affect the normal operation of components such as the power supply, communication cables, and liquid level gauge, and lead to inaccurate water level measurement. Therefore, an anti-icing device was designed to protect the reservoir's water measurement facilities.

[0052] Example 1

[0053] like Figures 1 to 7 As shown, in this embodiment, an anti-icing device based on a photovoltaic protection reservoir water measuring facility includes a floating shell 1. A guide through-hole 2 is provided at the center of the floating shell 1, which is gap-matched with the steel tube body b1. The guide through-hole 2 allows the floating shell 1 to slide up and down along the steel tube body b1. The floating shell 1 is arranged below the water surface and is immersed in the water as a whole. The interior of the shell body is a hollow structure, forming a sealed air cavity 3 and a content cavity 4. The two chambers are separated by a piston plate 5 that can slide up and down inside the floating shell 1, forming two independent chambers.

[0054] The one-way air outlet pipe group 10 is composed of several groups of air outlet pipes and one-way valves inside them. The above-mentioned one-way air outlet pipe group 10 is arranged on the top of the floating shell 1 and is connected through the air cavity 3; preferably, the one-way air outlet pipe group 10 is vertically arranged on the top of the floating shell 1, so that the gas can be ejected vertically upward, the thrust is consistent with the direction of gravity, there is no additional energy loss, and the thrust can reach the maximum value.

[0055] The impact ring 7 is fixed to the top of the buoyancy shell 1 via at least two sets of connecting columns 6, spaced apart. A one-way air inlet assembly 11, connected to the air cavity 3, is located within the connecting columns 6. This one-way air inlet assembly 11 consists of a one-way air inlet pipe and a one-way valve. This one-way air inlet assembly 11 fills the air cavity 3 with gas, increasing the buoyancy within the buoyancy shell 1. This gas, in turn, drives the impact ring 7 upward, increasing the distance from the stationary horizontal plane.

[0056] The flexible water bladder assembly 8, comprised of several groups of water bladders arranged in a circular array, is connected to the shell, with its inner side connected to the container chamber 4. When the piston plate 5 moves upward, the negative pressure generated by the container chamber 4 draws the inner surface of the flexible water bladder assembly 8 into the container chamber 4. At this point, the outer side of the flexible water bladder assembly 8 is filled with water, forming a counterweight that provides a certain amount of assistance for the downward propulsion of the buoyant shell 1. When the piston plate 5 moves downward, the positive pressure generated within the container chamber 4 drives the flexible water bladder assembly 8 to expand to the outside of the buoyant shell 1 and expel the water, thereby appropriately reducing the overall weight of the buoyant shell 1, achieving buoyancy compensation and facilitating ascent.

[0057] The lifting assembly 9 is placed in the container chamber 4 and is connected to the piston plate 5 in a transmission manner, driving the piston plate 5 to slide up and down in the floating shell 1; when the lifting assembly 9 drives the piston plate 5 to move upward, the reverse thrust of the gas discharged by the one-way air outlet pipe group 10 is used to push the floating shell 1 to drive the impact ring 7 downward to impact the water surface, thereby disturbing the water around the steel pipe body b1 to prevent it from freezing; when the lifting assembly 9 drives the piston plate 5 to move downward, the air cavity 3 inhales gas through the one-way pipe group, and under the action of buoyancy, drives the floating shell 1 and the impact ring 7 to move upward synchronously, thereby increasing the distance between the impact ring 7 and the horizontal plane, providing sufficient stroke for the next impact.

[0058] In the present invention, by inflating and exhausting the interior of the buoyancy shell 1, the impact ring 7, the one-way air outlet pipe assembly 10 and the flexible water bag assembly 8 are coordinated to prevent ice from forming around the steel pipe b1.

[0059] During the exhaust process, the gas in the air cavity 3 is discharged through the one-way air outlet pipe assembly 10. During the exhaust process, on the one hand, a reverse thrust is generated for the floating shell 1, so that it can move downward along the steel pipe body b1, driving the impact ring 7 to hit the water surface, thereby disturbing the water body; on the other hand, when the gas is discharged from the one-way air outlet pipe assembly 10, a group of bubbles with buoyancy is formed. When the bubbles reach the water surface and burst, the shock wave released causes the water surface to oscillate, thereby preventing the water body around the steel pipe body b1 from freezing.

[0060] During the alternating inflation and exhaust process, the flexible water bag group 8 realizes its own contraction and expansion under the alternating positive and negative pressures of the content chamber 4. In this process, it can exchange with the surrounding water, maintain the fluidity of the surrounding water, and prevent it from freezing.

[0061] On the other hand, the steel pipe water level gauge platform b is designed to accurately measure the water level. Several water inlet holes are distributed throughout the steel pipe b1, and a float is installed inside. The rise and fall of the float provides real-time water level measurement. However, the steel pipe b1, located below the water surface, is constantly exposed to pollutants such as floating algae and garbage. This can not only corrode the steel pipe b1, shortening its service life, but also easily clog the water inlet holes, which can seriously interfere with accurate water level measurement.

[0062] In this design, the configuration of a one-way air outlet pipe 10 not only causes the water surface to oscillate due to the discharged gas, but also solves the aforementioned problem. When the gas is discharged through the one-way air outlet pipe 10, the resulting bubbles burst in the water, causing the water surface to oscillate, producing an effect similar to ultrasonic cleaning. This structure not only thoroughly removes impurities adhering to the outer wall of the steel tube b1 and the water inlet, preventing impurity accumulation from interfering with water level measurement, but also effectively prevents damage to the steel tube b1 due to erosion by floating algae and debris, significantly extending its service life.

[0063] In this embodiment, the bottom of the buoy 1 is detachably connected to a counterweight 12 by bolts. The counterweight 12 is used to further calibrate the position of the buoy 1 underwater, ensuring that the one-way air outlet pipe assembly 10 is underwater and the impact ring 7 is located a preset distance above the water surface, thereby preventing the buoyancy of the buoy 1 from being excessively large and causing most of it to be above the water surface. Waterproof measures are taken between the counterweight 12 and the bottom of the buoy 1 to prevent water from entering the interior of the buoy 1. The corresponding installation of the lifting assembly 9 is above the counterweight 12. Figure 2 As shown, the lifting assembly 9 is installed on the counterweight block 12. After the floating shell 1 is lifted to the top, the counterweight block 12 below it is removed, and the lifting assembly 9 can be taken out for maintenance or repair.

[0064] In this embodiment, the counterweight 12 is conical in shape, with a sliding hole 13 at its center that forms a clearance fit with the steel tube b1. This conical structure reduces the resistance to the downward movement of the buoyant shell 1, allowing it to fall faster and significantly enhancing the impact of the impact ring 7 on the water surface.

[0065] In this embodiment, a tapered ring 14 is fixedly connected to the bottom surface of the impact ring 7; the tapered ring 14 can convert the kinetic energy of the impact into waves on the water body, so that a radially diffused concentric annular wave surface is formed on the water surface, thereby suppressing ice on the water surface.

[0066] In this embodiment, a plurality of groups of ice-breaking cones 15 are fixed to the bottom surfaces of the impact ring 7 and the tapered ring 14 respectively. If ice forms around the steel tube body b1, the ice-breaking cones 15 can cooperate with the impact ring 7 in the process of hitting the water surface to break the ice into small pieces, thereby reducing the impact force of the ice on the impact ring 7 and avoiding damage caused by the impact of the ice to a certain extent.

[0067] In this embodiment, the air outlet of the one-way air outlet tube group is in an inwardly contracted frustum structure, which can enhance the reverse thrust generated by the gas discharge, thereby enhancing the impact effect of the impact ring 7 on the water surface.

[0068] In this embodiment, a photovoltaic panel is provided above the floating shell 1, and the photovoltaic panel is electrically connected to the lifting assembly 9, realizing the conversion between solar energy and mechanical energy, so that the lifting assembly 9 obtains a sustainable power supply, which can reduce the dependence on external energy to a certain extent.

[0069] Example 2

[0070] In Embodiment 1, conventional lifting components 9 such as electric lifting rods and hydraulic rods can be adopted to achieve the function of inflating and exhausting air inside the floating shell 1, so as to disturb the water body around the steel pipe rack and prevent it from freezing. Based on Embodiment 1, this embodiment provides another lifting component 9, with no less than two groups provided, all located in the accommodating cavity 4. The lifting components 9 cooperate with each other to quickly discharge the gas in the air cavity 3, thereby increasing the downward thrust of the floating shell 1.

[0071] As Figure 3 shown, the lifting component 9 includes a base frame 91, the base frame 91 has a "C" - shaped structure, and a notch is opened at the top of the base frame 91; a spiral cam 92 and two guide rods 93, the spiral cam 92 and the guide rods 93 are both arranged inside the base frame 91, the two guide rods 93 are respectively fixed on both sides of the spiral cam 92, and the spiral cam 92 is driven to rotate by a rotating motor 94; a slider 95, the slider 95 is sleeved on the spiral cam 92 and the two guide rods 93, a spring 96 is commonly connected between the slider 95 and the base frame 91, and the spring 96 is respectively sleeved on the guide rods 93; a convex block 97, the convex block 97 is connected to both sides of the slider 95 and respectively moves along the spiral groove inside the spiral cam 92 to drive the slider 95 to move up and down; a push rod 98, the push rod 98 is connected above the slider 95, and the other end passes through the notch and is connected to the piston plate 5. Specifically, an intermediate plate is connected between the push rod 98 and the piston plate 5, and the intermediate plate and the piston plate 5 are detachably connected by bolts, which is convenient for completely disassembling the lifting component 9 from the bottom of the piston plate 5 for maintenance or replacement.

[0072] In this design, the rotating motor 94 drives the spiral cam 92 to rotate. When the spiral cam 92 rotates, it can drive the convex block 97 to move along the spiral groove line inside it, realizing the reciprocating movement of the push rod 98 to drive the piston plate 5, so as to realize the up - and - down sliding of the piston plate 5 inside the floating shell 1;

[0073] When the spiral cam 92 rotates, it drives the convex block 97 to move along the internal spiral groove; first, the convex block 97 drives the slider 95 to move downward, compressing the spring 96. As the spiral cam 92 rotates, the convex block 97 moves along the spiral groove and quickly moves upward under the action of the spring 96, thereby increasing the thrust of the piston plate 5 inside the floating shell 1 and quickly discharging the gas in its air cavity 3.

[0074] Furthermore, symmetrically distributed support seats 99 are connected below the base frame 91. The support seats 99 have an "L" - shaped structure, and reinforcing ribs are provided on the support seats 99. The rotating motor 94 is arranged between the two support seats 99; the bottom of the support seats 99 and the rotating motor 94 are detachably connected to the upper part of the counterweight 12 by bolts, which is convenient for disassembling them for subsequent maintenance or replacement.

[0075] Embodiment Three

[0076] like Figure 1-5 As shown, this embodiment further proposes a method for an anti-icing device based on a photovoltaic protected reservoir water measuring facility, which uses the anti-icing device based on a photovoltaic protected reservoir water measuring facility in any of the above embodiments, and includes the following steps:

[0077] S1, installation and positioning:

[0078] The anti-icing device based on the photovoltaic protection reservoir water measuring facility is mounted on the steel pipe b1 and is able to slide along the steel pipe b1;

[0079] S2, position calibration:

[0080] Adjust the axial positioning of the buoyancy shell 1 on the steel pipe body b1 so that the buoyancy shell 1 is completely immersed in the water body and the port of the one-way air outlet pipe assembly 10 is located below the water surface; the impact ring 7 ground is maintained at a preset distance from the still water surface through the connecting column 6;

[0081] S3, action execution:

[0082] The lifting assembly 9 drives the piston plate 5 to move upward, and the gas in the air cavity 3 is discharged at high speed through the one-way air outlet pipe assembly 10;

[0083] At the same time, under the action of negative pressure, the outside of the flexible water bag is filled with water and completely placed in the container cavity 4, increasing the total weight of the buoyancy shell 1; the gas reverse thrust pushes the buoyancy shell 1 and the impact ring 7 downward along the steel tube body b1;

[0084] The impact ring 7 hits the water surface, forming water surface waves, and the bubble group discharged by the one-way air outlet pipe group 10 bursts in the water, disturbing the water around the pipe body;

[0085] S4, reset;

[0086] The lifting assembly 9 drives the piston plate 5 downward, and the negative pressure generated in the air chamber 3 draws in external gas through the one-way air inlet assembly 11. The gas in the container chamber 4 is compressed and filled into the inside of the flexible water bag assembly 8, and then discharged out of the floating shell 1 to reduce its weight. The air chamber 3 is filled with gas to restore the buoyancy state, driving the impact ring 7 to float up along the steel pipe body b1 and return to the initial spacing.

[0087] S5, loop;

[0088] The above steps S3 to S4 are executed cyclically, so that the water around the steel pipe b1 maintains a dynamic flow state, and anti-icing is achieved under the synergistic effect.

[0089] In this method, the impact ring 7, the one-way air outlet pipe group 10 and the flexible water bag group 8 cooperate with each other to achieve the disturbance of the water body below the water surface and the impact on the water surface, thereby achieving the purpose of preventing ice from forming around the steel pipe body b1.

[0090] Although the above describes the specific implementation methods of the invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
