Description

Technical Field

[0001] This utility model belongs to the field of cold storage technology, specifically relating to a water-cooled storage tank structure. Background Technology

[0002] Cold storage technology is an energy-saving technology that stores cold energy during off-peak hours and releases it during peak hours. Its background stems from the increasing scarcity of energy resources and stricter environmental protection requirements. In traditional air conditioning systems, energy consumption is high during peak hours and low during off-peak hours, leading to energy waste and a burden. Therefore, to solve this problem, researchers began to study how to store cold energy during off-peak hours for use during peak hours, thereby reducing energy waste and costs. In ice-water cold storage systems, the ice storage tank is an important cold storage device. Cold storage technology utilizes peak-valley electricity policies. During off-peak hours at night, electric chillers store cold energy in the form of chilled water or other media. Then, during peak hours during the day, the chillers are not used or are used less frequently, making full use of the cold energy stored overnight for cooling, thus alleviating the demand for cooling during peak electricity hours.

[0003] A search revealed that patent number "CN202321606254.9" discloses "a cold storage tank structure for an ice-water cold storage system," which includes a main body of a cold storage tank box structure. The main body of the cold storage tank box structure has a cold storage tank cavity inside, which contains a storage medium for heat exchange to lower the temperature of the medium. A heat exchanger air pipe is installed in the upper part of the cold storage tank cavity to release the cold energy, which is then output through a duct. A heat exchanger liquid pipe is installed in the lower part of the cold storage tank cavity to assist in the heat exchange process. By employing multiple ice storage tanks arranged in parallel, compared to existing technologies, multiple cold storage circuits can operate independently, achieving non-interference among them. Even if one circuit fails, the entire system can continue to perform cold storage operations, enabling the entire device to operate efficiently. However, the use of cold storage tanks ensures minimal temperature fluctuations, but the aforementioned patent does not mention how to control the temperature. If the cold storage tank is affected by changes in external temperature, it can lead to a large temperature difference between the inside and outside, causing temperature changes within the cold storage tank and affecting the water temperature. Therefore, improvements are needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5The present invention provides the following technical solution: a water storage tank structure, including a storage tank body 1, a layered plate 2 installed inside the storage tank body 1, and the inside of the storage tank body 1 is divided into a first water tank 3 and a second water tank 4 by the layered plate 2, a first drain pipe 5 and a second drain pipe 6 symmetrically installed on the outer side wall of the storage tank body 1, a cover plate 15 connected to the top of the storage tank body 1, a sliding groove 16 opened on the side wall of the inner wall of the storage tank body 1, sliders 22 installed at both ends of the cover plate 15, a connecting plate 19 connected to one end of the cover plate 15, a limit pin 21 inserted into the surface of the connecting plate 19, and a docking block 20 connected to the front and rear ends of the storage tank body 1.

[0024] In a preferred embodiment: the slider 22 is adapted to the slide groove 16 and installed inside the slide groove 16, and the cover plate 15 is slidably connected to the slide groove 16 through the slider 22.

[0025] In a preferred embodiment: the top of the docking block 20 has an opening that matches the limiting pin 21, and the cover plate 15 is connected to the docking block 20 by means of the connecting plate 19 and the limiting pin 21.

[0026] In a preferred embodiment: a cooling water pump 7 is installed on the surface of the first drain pipe 5, and a first control valve 8 and a first temperature sensor 9 are also connected to the surface of the first drain pipe 5. A first monitoring panel 10 is installed on the outer wall of the cold storage tank body 1 near the first drain pipe 5.

[0027] In a preferred embodiment: a cold water pump 11 is installed on the surface of the second drain pipe 6, and a second control valve 12 and a second temperature sensor 13 are also connected to the surface of the second drain pipe 6. A second monitoring panel 14 is installed on the outer wall of the cold storage tank body 1 near the second drain pipe 6.

[0028] In this embodiment, firstly, the cold storage tank body 1 belongs to the existing central air conditioning water storage technology. The working principle of the cold storage tank body 1 is not significantly related to the existing technology, so the working principle will not be described in detail here. At the same time, the second temperature sensor 13 and the first temperature sensor 9 described in this article also belong to the existing technology. The model of the second temperature sensor 13 and the first temperature sensor 9 is BD-PT100-X. The second temperature sensor 13 and the first temperature sensor 9 are electrically connected to the second monitoring panel 14 and the first monitoring panel 10, respectively. The second monitoring panel 14 and the first monitoring panel 10 provide feedback on the temperature monitored by the second temperature sensor 13 and the first temperature sensor 9. The subsequent steps will not be described in detail here. The cold storage tank body 1 is used for cooling at night. When the electricity price is low at night, it stores cold water, which saves energy and is very meaningful.

[0029] When the first drain pipe 5 drains water using the cooling water pump 7, the cooling water pump 7 can draw cold water from the inside of the cold storage tank 1 from the first drain pipe 5. Before this, the first control valve 8 needs to be opened. Then, when the first drain pipe 5 drains water, the first temperature sensor 9 can monitor the water temperature and then feed it back to the first monitoring panel 10 for display, so as to understand whether the water temperature is normal and meets the requirements. At the same time, when the second drain pipe 6 drains water using the cold storage water pump 11, its principle is the same as the cooperation between the cooling water pump 7 and the first drain pipe 5. Then, the second temperature sensor 13 can monitor the water temperature and feed it back to the second monitoring panel 14 for display, so as to understand whether the water temperature is normal and meets the requirements.

[0030] It should be noted that the cover plate 15 can be opened at the top of the cold storage tank body 1 by the cooperation of the slider 22 and the slide groove 16. First, pull out the limit pin 21 to disconnect it from the docking block 20, and then pull the cover plate 15 outward.

[0031] Example 2

[0032] Please see Figure 1-5 The cold storage tank body 1 is equipped with a filter screen 17 inside, and the filter screen 17 is adapted to be installed in the first water tank 3 and the second water tank 4. The inner wall of the cold storage tank body 1 is equipped with a heat insulation layer 18.

[0033] In a preferred embodiment: the insulation layer 18 is made of 100mm polyurethane foam material, and the insulation layer 18 is attached to the inner wall of the cold storage tank body 1.

[0034] In the embodiments, as described in Embodiment 1, after water is stored in the cold storage tank body 1, the insulation layer 18 can isolate the water from contact with the inner wall of the cold storage tank body 1, preventing the water from being affected by changes in the external temperature of the cold storage tank body 1, allowing the temperature to be transferred to the inner wall of the cold storage tank body 1, thereby affecting the stability of the water temperature. The filter screen 17 can filter impurities in the water, reducing the amount of impurities entering the first drain pipe 5 and the second drain pipe 6.

[0035] In summary, as described in Embodiments 1 and 2, the insulation layer 18 can isolate the water from contact with the inner wall of the cold storage tank body 1, preventing the water from being affected by changes in the external temperature of the cold storage tank body 1, which would allow the temperature to be transferred to the inner wall of the cold storage tank body 1 and thus affect the stability of the water temperature. At the same time, by utilizing the cooperation between the second temperature sensor 13 and the first temperature sensor 9, the water temperature inside the cold storage tank body 1 can be detected as it is discharged through the first drain pipe 5 and the second drain pipe 6, thereby improving the practicality of the water cold storage tank structure.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
