Detailed implementation mode

[0029] In order to make the purpose, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] It should be noted that in the description of the present invention, the terms indicating the direction or positional relationship such as "upper", "lower", "left", "right", "inner", "outer", etc. are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] As Figure 1 shown, the steel pipe type water level gauge platform b is fixed at the water-facing side of the reservoir dam a. The steel pipe body b1 extends vertically downward into the water, and the lower part of the steel pipe body b1 extends at least 1 m below the dead water level of the reservoir, and the upper part extends at least 1.5 m above the maximum historical water level of the reservoir; an operation platform b2 is arranged above the steel pipe body b1 to facilitate the maintenance of the equipment, and components such as a rain gauge device, a lightning rod device, and a solar power supply device b3 are arranged on the operation platform b2.

[0034] However, this structure has certain problems. In winter, when the temperature is relatively low and the water surface freezes, affected by ice cones, it will repeatedly collide with the steel pipe body b1, which is likely to cause it to bend, affecting the normal operation of components such as power supply, communication cables, and liquid level gauges, making the water level gauge measurement inaccurate. Therefore, an anti-icing device for protecting the water measurement facilities of the reservoir is designed.

[0035] Embodiment 1 As Figures 1 to 7 shown, in this embodiment, an anti-icing device for protecting the water measurement facilities of the reservoir based on photovoltaic includes a floating shell 1. A guiding through hole 2 that is in clearance fit with the steel pipe body b1 is provided at the center of the floating shell 1. Through the guiding through hole 2, the floating shell 1 can slide up and down along the steel pipe body b1. The floating shell 1 is arranged below the water surface and is integrally immersed in the water body. The inside of the shell body is a hollow structure, forming a sealed air cavity 3 and a content cavity 4. The two cavities are separated by a piston plate 5 that can slide up and down inside the floating shell 1, forming two independent cavities.

[0036] The one-way air outlet pipe group 10 is composed of a plurality of groups of air outlet pipes and one-way valves therein. The 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.

[0037] The impact ring 7 is fixed to the top of the floating shell 1 at intervals through at least two groups of connecting columns 6. A one-way air inlet pipe group 11 connected to the air cavity 3 is arranged inside the connecting column 6. The one-way air inlet pipe group 11 is composed of a one-way air inlet pipe and a one-way valve. The air cavity 3 is filled with gas through the one-way air inlet pipe group 11 to increase the buoyancy inside the floating shell 1, so that it drives the impact ring 7 to float up and increase the distance between it and the static horizontal plane.

[0038] The flexible water bag group 8 is composed of a plurality of water bags connected to the shell in a circular array, and the inner side of the flexible water bag group 8 is connected to the container chamber 4. When the piston plate 5 moves upward, the negative pressure formed by the container chamber 4 adsorbs the inner surface of the flexible water bag group 8 into the container chamber 4. At this time, the outer side of the flexible water bag group 8 is filled with water to form a counterweight, which provides a certain amount of assistance for the floating shell 1 to move downward; when the piston plate 5 moves downward, the positive pressure generated in the container chamber 4 drives the flexible water bag group 8 to expand to the outside of the floating shell 1 and discharge the water, thereby appropriately reducing the overall weight of the floating shell 1, realizing buoyancy compensation and facilitating floating.

[0039] The lifting component 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 component 9 drives the piston plate 5 to move upward, the reverse thrust of the gas discharged from the one-way air outlet pipe group 10 is used to push the floating shell 1 to drive the impact ring 7 to impact the water surface downward, thereby disturbing the water around the steel pipe body b1 to prevent it from freezing; when the lifting component 9 drives the piston plate 5 to move downward, the air cavity 3 inhales gas through the one-way pipe group, and drives the floating shell 1 and the impact ring 7 to move upward synchronously under the action of buoyancy, thereby increasing the distance between the impact ring 7 and the horizontal plane, providing sufficient stroke for the next impact. In the present invention, the impact ring 7, the one-way air outlet pipe group 10 and the flexible water bag group 8 are coordinated by inflating the air inside the floating shell 1 to achieve the purpose of preventing ice from forming around the steel pipe body b1.

[0040] In the exhaust link, the gas in the air cavity 3 is discharged through the one-way air outlet pipe group 10. During the exhaust process, on the one hand, a reverse thrust is formed for the floating shell 1, so that it can move downward along the steel tube 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 group 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 tube body b1 from freezing.

[0041] During the alternating process of charging and discharging, the flexible water bag group 8 realizes its own contraction and expansion under the alternating positive and negative pressures of the content cavity 4. During this process, it can form an exchange with the surrounding water body, maintain the fluidity of the water body around it, and avoid icing.

[0042] On the other hand, for the steel pipe type water level gauge platform b to achieve accurate water level measurement. A number of groups of water inlet holes are distributed on the steel pipe body b1, and a float is arranged inside. The current water level is measured in real time through the lifting of the float. However, the steel pipe body b1 below the water surface is long-term invaded by pollutants such as floating algae and garbage in the water, which may not only cause the steel pipe body b1 to be eroded and shorten its service life, but also easily cause the water inlet holes to be blocked. Once blocked, it will seriously interfere with the accuracy of water level measurement.

[0043] In this design, the configuration of the one-way air outlet pipe 10 can solve the above problems while discharging gas to cause water surface oscillation. When the gas is discharged through the one-way air outlet pipe 10, the formed bubble group breaks in the water, prompting the water surface to oscillate and producing an effect similar to ultrasonic cleaning. This structure can not only completely remove the impurities attached to the outer wall of the steel pipe body b1 and the water inlet holes, avoid interference with water level measurement caused by impurity accumulation, but also effectively prevent the steel pipe body b1 from being damaged by the erosion of floating algae and garbage, and significantly extend its service life.

[0044] In this embodiment, a counterweight 12 is detachably connected to the bottom of the floating shell 1 through bolts. The position of the floating shell 1 underwater is further calibrated through the counterweight 12 to ensure that the one-way air outlet pipe group 10 is underwater and the impact ring 7 is at a preset distance above the water surface, avoiding the floating shell 1 having too much buoyancy and causing most of it to be above the water surface; a waterproof measure is taken between the counterweight 12 and the bottom of the floating shell 1 to prevent water from entering the inside of the floating shell 1; the lifting assembly 9 is installed above the counterweight 12. As Figure 2 shown, the lifting assembly 9 is installed on the counterweight 12. After lifting the floating shell 1 to the upper part, the counterweight 12 below it can be removed, and the lifting assembly 9 can be taken out for maintenance or overhaul.

[0045] In this embodiment, the counterweight 12 has a conical structure, and a sliding through hole 13 with a clearance fit with the steel pipe body b1 is provided at the center of the counterweight 12. Through the conical structure, the resistance of the floating shell 1 moving downward can be reduced, enabling it to obtain a faster falling speed, and significantly enhancing the hitting effect of the impact ring 7 on the water surface.

[0046] In this embodiment, a taper ring 14 is fixedly connected to the bottom surface of the impact ring 7; this taper ring 14 can convert the impact kinetic energy into fluctuations of the water body, so as to form a concentric ring wave surface with radial diffusion on the water surface, thereby inhibiting the icing of the water surface.

[0047] In this embodiment, several groups of ice-breaking cones 15 are respectively fixed to the bottom surfaces of the impact ring 7 and the taper ring 14. When icing occurs around the steel pipe body b1, during the process of the impact ring 7 hitting the water surface, in cooperation with the ice-breaking cones 15, the ice-breaking cones 15 can first break the ice into small pieces, thereby reducing the impact force of the ice on the impact ring 7 and avoiding damage caused by ice impact to a certain extent.

[0048] In this embodiment, the air outlet of the unidirectional air outlet pipe group has a frustum-shaped structure that contracts inward. This structure can enhance the reaction force generated by gas discharge, thereby enhancing the hitting effect of the impact ring 7 on the water surface.

[0049] In this embodiment, a photovoltaic panel 16 is provided above the floating shell 1. The photovoltaic panel 16 is electrically connected to the lifting assembly 9, realizing the conversion from solar energy to mechanical energy, enabling the lifting assembly 9 to obtain sustainable power supply, and reducing the dependence on external energy to a certain extent.

[0050] Embodiment 2 In Embodiment 1, conventional lifting assemblies 9 such as electric lifting rods and hydraulic rods can be used to achieve the function of inflating and exhausting the floating shell 1, thereby disturbing the water body around the steel pipe rack and preventing it from icing. On the basis of Embodiment 1, this embodiment provides another lifting assembly 9. There are no less than two groups of lifting assemblies 9, all located in the accommodation cavity 4. The lifting assemblies 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.

[0051] As Figure 3 shown, the lifting assembly 9 includes a base frame 91. The base frame 91 has a "C" - shaped structure, and a notch is provided 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. 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 grooves 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, facilitating the complete disassembly of the lifting assembly 9 from the bottom of the piston plate 5 for maintenance or replacement.

[0052] In this design, the rotation of the rotary motor 94 drives the spiral cam 92 to rotate. When the spiral cam 92 rotates, it can drive the lug 97 to move along the spiral groove line inside it, realizing the reciprocating motion of the push rod 98 to drive the piston plate 5, thereby realizing the up and down sliding of the piston plate 5 in the floating shell 1. When the spiral cam 92 rotates, it drives the lug 97 to move along the internal spiral groove; first, the lug 97 drives the slider 95 to move downward, compressing the spring 96. As the spiral cam 92 rotates, the lug 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 in the floating shell 1 and quickly discharging the gas in its air chamber 3.

[0053] Furthermore, symmetrically distributed support seats 99 are connected below the base frame 91. The support seats 99 are in an "L" shape structure, and reinforcing ribs are provided on the support seats 99. The rotary motor 94 is arranged between the two support seats 99; the bottom of the support seats 99 and the rotary motor 94 are detachably connected to the upper part of the counterweight block 12 through bolts, so as to facilitate the disassembly for subsequent maintenance or replacement.

[0054] Embodiment III As Figures 1 - 5 shown, this embodiment also proposes a method for an anti-icing device based on a photovoltaic-protected reservoir water measuring facility. Using the anti-icing device based on the photovoltaic-protected reservoir water measuring facility in any of the above embodiments, it includes the following steps: S1, Installation and positioning: The anti-icing device based on the photovoltaic-protected reservoir water measuring facility is sleeved on the steel pipe body b1 and can slide along the steel pipe body b1. S2, Position calibration: Adjust the axial positioning of the floating shell 1 on the steel pipe body b1 so that the entire floating shell 1 is immersed in the water body, and the port of the one-way air outlet pipe group 10 is below the water surface; the ground of the impact ring 7 is kept at a preset distance from the static water surface through the connecting column 6. S3, Action execution: The lifting assembly 9 drives the piston plate 5 to move upward, and discharges the gas in the air chamber 3 at high speed through the one-way air outlet pipe group 10. At the same time, under the negative pressure, the outer side of the flexible water bag is filled with water and is completely placed in the accommodating cavity 4, increasing the total weight of the floating shell 1; the gas reaction thrust pushes the floating shell 1 and the impact ring 7 to move downward along the steel pipe body b1. The impact ring 7 impacts the water surface, forming water surface fluctuations, and cooperating with the bubble group discharged by the one-way air outlet pipe group 10 to break in the water body, disturbing the water body around the pipe body. S4, Reset; The lifting component 9 drives the piston plate 5 to move downward, and the negative pressure generated in the air chamber 3 sucks the outside air through the one-way intake pipe group 11; the gas in the content chamber 4 is compressed and filled into the inner side of the flexible water bag group 8, and discharges it outside the floating shell 1 to reduce the weight; the air chamber 3 is filled with gas, restores the buoyancy state, drives the impact ring 7 to float upward along the steel pipe body b1, and restores to the initial distance; S5, loop; Loop and execute the above S3 to S4 to keep the water body around the steel pipe body b1 in a dynamic flow state, and achieve anti-icing under the synergistic effect.

[0055] In this method, through the synergistic cooperation of the impact ring 7, the one-way exhaust pipe group 10 and the flexible water bag group 8, the disturbance of the water body below the water surface and the hitting of the water surface are realized, so as to achieve the purpose of preventing icing around the steel pipe body b1.

[0056] Although the specific implementation manners of the invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the invention. Based on the technical solutions of the invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the invention.
