Description

Technical Field

[0001] The utility model relates to the technical field of pond deicing, in particular to a simple and environmentally friendly pond deicer. Background Art

[0002] In winter, small water bodies such as ponds are prone to ice formation. For aquaculture, long-term ice cover not only affects the oxygen exchange of water bodies, but may also cause the death of aquatic organisms due to lack of oxygen.

[0003] In addition, ice also blocks sunlight and affects the photosynthesis of aquatic plants, thus having a negative impact on the aquatic ecosystem. Therefore, pond de-icing is necessary in aquaculture and ecological protection.

[0004] Currently, there are several solutions for pond deicing on the market.

[0005] For example, the patent "Surface Heating Pond De-icer" with application number 201920748050.6 consists of an upper cover, a lower cover, a heating cup body and a spiral heating wire, etc., and can be suspended above the pond for de-icing. However, the structure of this de-icer is relatively complex, and it is necessary to use a spiral heating wire to heat the upper cover at the same time to prevent it from being covered by snow or ice, and the heating cup body is also required to heat and de-ice below the water surface. This dual heating mechanism not only increases the manufacturing cost, but also due to its nature of use on water, the complex structure also leads to a complex sealing design, which may affect the durability of the equipment.

[0006] In order to circumvent the problems caused by this complex structure, the industry adopts some simplified design solutions. For example, simple ice-breaking devices such as icebreakers or manual ice-breaking tools are used to physically break the ice. However, these methods require a lot of manpower or mechanical equipment investment, which is not practical for small ponds or home users.

[0007] Another common method is to use chemical deicing agents. However, this method will pollute the water body and have potential toxic effects on aquatic organisms, which does not meet the requirements of environmental protection and sustainable development.

[0008] Another common practice is to increase the fluidity of the water body and stir the water body through equipment such as water pumps or air pumps to prevent freezing. However, this method consumes a lot of energy, and long-term operation will increase equipment wear and maintenance costs.

[0009] Therefore, how to design a pond deicing device with simple structure, low cost, high efficiency and environmental protection has become the technical problem to be solved by the utility model. Utility Model Content

[0021] As a further solution of the utility model, the shape of the lower shell is designed to be hemispherical.

[0022] As a further solution of the utility model, the power avoidance hole is arranged in the middle of the bottom end of the heat-conducting metal shell.

[0023] As a further solution of the utility model, the de-icer also includes a leakage protection switch, which is arranged on the power supply line and is used to cut off the power supply when leakage is detected.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. A single heating structure can melt ice and prevent the upper surface of the de-icer from being covered by snow or ice, thereby simplifying the structure and making it easy to manufacture and maintain.

[0026] 2. De-icing is carried out by heat conduction through the heat-conducting metal shell, and the large surface area of ​​the metal shell is utilized to achieve a wider de-icing range, thereby improving the de-icing efficiency and allowing the ice in a larger area to melt quickly.

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 —6. In an embodiment of the utility model, a simple and environmentally friendly pond de-icer comprises a heat-conducting metal shell 1, which is constructed with a closed shell cavity 2; a heating element 3 is fixedly installed in the shell cavity 2, and the heating element 3 is thermally connected to the heat-conducting metal shell 1; the heat-conducting metal shell 1 is provided with a power avoidance hole 4 connected to the shell cavity 2, and the heating element 3 comprises a power connection part 5, and the power connection part 5 extends to the outside of the heat-conducting metal shell 1 through the power avoidance hole 4, or one end of the power supply line 6 extends to the shell cavity 2 through the power avoidance hole 4.

[0040] When the power connection part 5 extends to the outside of the heat-conducting metal shell 1 through the power avoidance hole 4, the power connection part 5 of the heating element 3 is tightly connected to the heat-conducting metal shell 1 through the sealing member 7 to close the gap between the power avoidance hole 4 and the power connection part 5; when one end of the power supply line 6 extends into the shell cavity 2 through the power avoidance hole 4, the outer side surface of the power supply line 6 is tightly connected to the heat-conducting metal shell 1 through the sealing member 7 near one end thereof to close the gap between the power avoidance hole 4 and the line. Among them, regarding the specific method of tightly connecting to close the gap, for example, materials such as sealant, rubber gasket, waterproof tape, etc. can be used to ensure that the gap between the power avoidance hole and the power connection part or line is completely closed. During implementation, the sealing material can be placed at the gap first, and then the upper shell cover and the lower shell are tightly pressed together by tightening screws, snaps or other connection methods, so as to achieve the closure of the gap, which are all extended implementation methods that can be known to ordinary technicians in this field.

[0041] The simple and environmentally friendly pond de-icer also includes an annular heat-conducting metal sheet 8, which is arranged in the shell cavity 2 and tightly sleeved on the outside of the heating element 3. The annular heat-conducting metal sheet 8 includes an annular lower end surface 9. A contact plane 16 that fits the annular lower end surface 9 is provided at the bottom of the shell cavity 2. The annular heat-conducting metal sheet 8 is thermally contacted and connected to the heat-conducting metal shell 1 through the contact plane 16.

[0042] The simple and environmentally friendly pond de-icer also includes a control module 10 and an insulation column 11, wherein the control module 10 is fixed on the top of the heating element 3 through the insulation column 11, and the heating element 3 is electrically connected to the control module 10. The heat-conducting metal shell 1 includes a lower shell 12 and an upper shell cover 13, the lower shell 12 has an upper surface, the upper surface is provided with a groove cavity 14, the groove cavity 14 is provided with an annular connection notch 15 that matches the upper shell cover 13 at the notch, the upper shell cover 13 is pressed on the lower shell 12 through the annular connection notch 15, and forms a sealed connection with the lower shell 12. The heating element 3 is made of cast aluminum. The shape of the lower shell 12 is designed to be hemispherical. The power avoidance hole 4 is arranged in the middle of the bottom end of the heat-conducting metal shell 1.

[0043] The de-icer further comprises a leakage protection switch, which is arranged on the power supply line 6 and is used for cutting off the power supply when leakage is detected.

[0044] Among them, the leakage protection switch is integrated on the power supply line 6, and its core function is to quickly and automatically cut off the power supply when leakage is detected in the line. Its principle is to adopt current detection technology, which can monitor the current change in the power supply line in real time. Once the current is abnormal, such as leakage, that is, the current flows to an unexpected path, the leakage protection switch will immediately act to cut off the power supply, thereby effectively preventing electric shock accidents or equipment damage caused by leakage. Its structure is that a current transformer is installed inside the leakage protection switch to monitor the current in the line. Under normal working conditions, the current in the power supply line is balanced, that is, the current flowing in and out is equal. However, once leakage occurs, this balance will be broken, and the leakage protection switch will immediately detect this imbalance and quickly cut off the power supply through its internal circuit breaker. It belongs to the ordinary technicians in the field and can be known to the extended implementation method. Through the addition of the leakage protection switch, not only the safety performance of the simple and environmentally friendly pond de-icer is significantly improved, but also additional safety protection is provided for users. In actual use, even in severe weather conditions such as rain, snow, humidity and other environments, users can use the de-icer with confidence without worrying about the safety risks of leakage to pond aquatic organisms.

[0045] Embodiment 1:

[0046] The present embodiment provides a simple and environmentally friendly pond deicer, which is designed to solve the problems of complex structure, high cost, insufficient durability and environmental protection in existing pond deicing solutions.

[0047] Specifically, the deicer includes a heat-conducting metal shell 1, which is composed of a lower shell 12 and an upper shell cover 13. The lower shell 12 is designed to be hemispherical to increase the contact area with the ice surface and improve the heat conduction efficiency. The upper shell cover 13 and the lower shell 12 are tightly pressed together through an annular connection notch 15 to form a sealed connection to ensure the waterproof performance in the shell cavity 2.

[0048] A heating element 3 is fixedly installed in the shell cavity 2. The heating element 3 is made of cast aluminum and has good thermal conductivity. The heating element 3 is connected to the heat-conducting metal shell 1 through heat conduction, ensuring that heat can be evenly and efficiently transferred to the metal shell, thereby melting the contacted ice layer.

[0049] In order to further improve the heat conduction efficiency, an annular heat-conducting metal sheet 8 is also provided in the shell cavity 2, which is tightly sleeved on the outer side of the heating element 3. The annular heat-conducting metal sheet 8 includes an annular lower end surface 9, which fits with the contact plane 16 at the bottom of the shell cavity 2, thereby forming a heat-conducting contact connection with the heat-conducting metal shell 1 through the contact plane 16. This design helps to spread the heat generated by the heating element 3 more evenly over the entire metal shell.

[0050] In addition, the deicer further includes a control module 10 and a heat-insulating column 11. The power supply line 6 is electrically connected to the control module 10, and the control module 10 is fixed to the top of the heating element 3 through the heat-insulating column 11 and is electrically connected to the heating element 3. This design can conveniently adjust the working state of the heating element 3 through the control module 10 to achieve intelligent control.

[0051] For example, the control module 10 is responsible for monitoring and adjusting the working state of the heating element 3. Specifically, the control module 10 generally includes the following key parts:

[0052] Microprocessor / microcontroller: This is the core of the control module, responsible for processing various sensor data, making decisions according to preset programs or algorithms, and controlling the working state of the heating element 3.

[0053] Temperature sensor: used to monitor the temperature around the de-icer in real time to ensure that the heating element 3 works at a suitable temperature, neither too hot nor too cold.

[0054] Power management circuit: responsible for providing a stable power supply to the heating element 3, and adjusting the current and voltage according to the instructions of the microprocessor, so as to control the heating power of the heating element.

[0055] In its specific implementation, an Arduino-based microcontroller can be selected as the core of the control module. Through programming, we can set the heating element 3 to automatically start heating when the temperature sensor detects that the ambient temperature is lower than a certain threshold (such as -5°C). At the same time, we can also manually adjust the heating power or set the timer switch through the buttons on the user interface. The main function of the insulation column 11 is to isolate the heat transfer between the control module 10 and the heating element 3 to prevent the high temperature generated by the heating element 3 from damaging the control module. The insulation column 11 can be made of a high-performance insulation material such as polytetrafluoroethylene (PTFE). These materials have excellent insulation performance and high temperature resistance, which can ensure that the control module maintains a normal working temperature when the heating element is working. In terms of structural design, the insulation column 11 is usually designed to be cylindrical or conical to adapt to the spatial layout between the heating element 3 and the control module 10. It may contain multiple layers of insulation material or air gaps inside to further enhance the insulation effect.

[0056] A power avoidance hole 4 is provided in the middle of the bottom end of the heat-conducting metal shell 1 for connecting the power supply line 6. In this embodiment, one end of the power supply line 6 extends into the shell cavity 2 through the power avoidance hole 4 and is connected to the heating element 3. In order to ensure the sealing performance, the outer side surface of the power supply line 6 is tightly connected to the heat-conducting metal shell 1 through a sealing member 7 near one end thereof to close the gap between the power avoidance hole 4 and the line.

[0057] When the simple and environmentally friendly pond de-icer is used, it only needs to be placed on the surface of the frozen pond. The heating element 3 is started by the control module 10, and the heat generated by the heating element 3 is evenly transferred to the ice layer through the heat-conducting metal shell 1 and the annular heat-conducting metal sheet 8, thereby effectively melting the ice layer. Due to its simple structure, low cost, environmental protection and high efficiency, the de-icer is particularly suitable for small ponds or home users.

[0058] Compared with the prior art, the simple and environmentally friendly pond de-icer provided in this embodiment has significant advantages: first, its structure is simple and the cost is low, which is convenient for large-scale production and promotion and application; second, the heat conduction efficiency is improved by optimizing the heat conduction path and adding the design of the annular heat-conducting metal sheet 8; finally, the de-icer does not require the addition of any chemical snow-melting agent during use, which meets the requirements of environmental protection and sustainable development.

[0059] Embodiment 2:

[0060] This embodiment describes in detail a simple and environmentally friendly pond deicer, and its design still focuses on providing a simple, low-cost, efficient and environmentally friendly solution to meet customers' actual needs for pond deicing.

[0061] The core component of the simple and environmentally friendly pond de-icer is a heat-conducting metal shell 1, which is designed with special emphasis on simplicity and practicality. The heat-conducting metal shell 1 is made of a lightweight material with good thermal conductivity, such as aluminum alloy, to ensure that the device is both lightweight and efficient. The metal shell is designed in a flat disc shape, which is convenient for stable floating placement on the ice surface, and is also convenient for carrying and storage.

[0062] A low-cost heating element 3, such as a PTC ceramic heater, is installed in the shell cavity 2, which can heat up quickly in a short time and transfer the heat evenly to the ice layer through the heat-conducting metal shell 1. The heat conduction connection between the heating element 3 and the heat-conducting metal shell 1 is optimized to reduce heat loss and improve thermal efficiency.

[0063] In order to further improve the deicing efficiency, the bottom surface of the heat-conducting metal shell 1 is treated with a high thermal conductivity coating, which helps to transfer more heat directly to the ice layer and accelerate the melting process. At the same time, the structural design of the entire deicer is very compact, without redundant complex parts, which not only reduces the manufacturing cost, but also improves the reliability and durability of the equipment.

[0064] In terms of power connection, this embodiment adopts a simple design. A power avoidance hole 4 is provided on one side of the heat-conducting metal shell 1, allowing the power line to be directly connected to the heating element 3. In order to ensure waterproof and dustproof performance, the power avoidance hole 4 is equipped with a dedicated sealing member 7, such as a waterproof joint, thereby ensuring the normal operation of the device under adverse weather conditions.

[0065] In actual application, the user only needs to place the simple and environmentally friendly pond de-icer on the surface of the frozen pond, and after turning on the power, the heating element 3 starts to work and transfers heat to the ice layer through the heat-conducting metal shell 1. As time goes by, the ice layer gradually melts to form an ice-free area, thereby restoring the oxygen exchange and sunlight exposure of the water body and protecting the living environment of aquatic organisms.

[0066] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0067] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
