Description

Technical Field

[0001] This utility model belongs to the field of cold storage tank technology, and in particular relates to a cold storage tank with an automatic exhaust and pressure reduction device. Background Technology

[0002] Data centers are a critical IT infrastructure that typically houses critical applications, data, and physical equipment. These devices continuously generate heat during normal operation. In the event of an emergency such as a power outage, without backup power, the air conditioning system will be unable to function properly and may not be able to provide the necessary cooling services to the data center. To address this situation, cold storage tank systems have been designed. When the power supply is interrupted, the cold storage tank can provide emergency cooling for the air conditioning system, thereby maintaining the normal operation of the data center.

[0003] Existing cold storage tanks typically operate by circulating water, with hot and cold water flowing within the tank. When the water is at a high temperature, the internal pressure increases. During the reflux process, air or bubbles may appear in the pipes. Combined with the high pressure of the hot water itself, this can lead to excessive internal pressure, causing serious problems such as equipment damage or tank expansion. Utility Model Content

[0004] This utility model addresses the problem that existing cold storage tanks typically operate through water circulation, where hot and cold water circulate within the tank. High-temperature water increases internal pressure, and during the return flow, air or bubbles may form in the pipes. Combined with the already high pressure of the hot water, this can lead to excessive internal pressure, causing equipment damage or serious problems such as tank expansion. The following technical solution is proposed:

[0005] A cold storage tank with an automatic venting and pressure reducing device includes a tank body. An inlet pipe is fixedly connected to the outer surface of the tank body, and an outlet pipe is fixedly connected to the outer surface of the tank body below the inlet pipe. A fixed plate is fixedly installed inside the tank body above the inlet pipe. A movable plate is movably connected inside the fixed plate. A cylinder is fixedly connected to the top of the movable plate. A fixed rod is fixedly connected to the outer surface of the cylinder. One end of the fixed rod is fixedly connected to the inside of the tank body. A pressure sensor is fixedly installed inside the fixed plate at the side of the movable plate. An venting assembly is movably connected to the top of the tank body.

[0006] Preferably, the exhaust assembly includes an exhaust pipe movably connected to the inside of the top of the tank. The exhaust pipe has multiple exhaust holes at both the top and bottom. The bottom of the exhaust pipe has multiple slots, and a locking block is engaged inside each slot. A rubber plug is fixedly connected to the top of each locking block, and a collection groove is fixedly connected to the bottom of each locking block.

[0007] Preferably, the bottom of the fixing plate is at a higher level than the top of the water inlet pipe.

[0008] Preferably, the center of the cylinder and the center of the movable plate are on the same vertical line.

[0009] Preferably, the top of the collection groove is formed into an arc-shaped surface located inside the card block.

[0010] Preferably, the rubber stopper is frustum-shaped, and the diameter of the top end of the rubber stopper is smaller than the diameter of the bottom end.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) It can automatically adjust the pressure inside the cold storage tank, effectively improve the gas discharge rate, and ensure that the cold storage tank will not be damaged or expand due to excessive internal pressure, thereby improving the protection of the cold storage tank.

[0013] (2) It can simplify the installation process of the collection tank, and can quickly disassemble and install the collection tank, making it convenient to thoroughly clean the collection tank, effectively improving the cleaning efficiency of the collection tank, thereby improving the maintenance efficiency of the collection tank.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1: This utility model provides a cold storage tank with an automatic exhaust and pressure reduction device, such as... Figures 1 to 4As shown, the device includes a tank 1, an inlet pipe 2 fixedly connected to the outer surface of the tank 1, an outlet pipe 3 fixedly connected to the outer surface of the tank 1 below the inlet pipe 2, a fixed plate 4 fixedly installed inside the tank 1 above the inlet pipe 2, a movable plate 5 movably connected inside the fixed plate 4, a cylinder 6 fixedly connected to the top of the movable plate 5, a fixed rod 7 fixedly connected to the outer surface of the cylinder 6, one end of the fixed rod 7 fixedly connected to the inside of the tank 1, a pressure sensor 8 fixedly installed inside the fixed plate 4 at the side of the movable plate 5, the pressure sensor 8 and the cylinder 6 being electrically connected, and an exhaust assembly 9 movably connected inside the top of the tank 1.

[0021] like Figure 1 and Figure 4 As shown, the exhaust assembly 9 includes an exhaust pipe 91 movably connected to the inside of the top of the tank 1. Multiple exhaust holes 92 are provided inside both the top and bottom of the exhaust pipe 91. Multiple slots 93 are provided inside the bottom of the exhaust pipe 91, and locking blocks 94 are engaged inside the slots 93. A rubber stopper 95 is fixedly connected to the top of the locking block 94, and a collection groove 96 is fixedly connected to the bottom of the locking block 94. With prolonged use of the exhaust assembly 9, a large amount of dust and debris will accumulate inside the collection groove 96. Therefore, the exhaust assembly 9 should first be removed from the inside of the tank 1. Next, the collection slot 96 is moved downwards. The movement of the collection slot 96 causes the locking block 94 and the rubber plug 95 to move synchronously. As the collection slot 96 moves slowly, when the locking block 94 and the rubber plug 95 are no longer in contact with the slot 93, the collection slot 96 is removed, making it convenient to clean the collection slot 96. This simplifies the installation process of the collection slot 96, allows for quick disassembly and installation of the collection slot 96, facilitates thorough cleaning of the collection slot 96, and effectively improves the cleaning efficiency of the collection slot 96, thereby improving the maintenance efficiency of the collection slot 96.

[0022] like Figure 1 and Figure 2 As shown, the bottom of the fixing plate 4 is at a higher level than the top of the water inlet pipe 2, ensuring that the water source inside the tank 1 is located below the fixing plate 4, and ensuring that the air pressure sensor 8 can work normally.

[0023] like Figure 1 and Figure 2 As shown, the center of cylinder 6 and the center of movable plate 5 are on the same vertical line, ensuring that the position of movable plate 5 will not shift when it moves, and ensuring that movable plate 5 can work normally.

[0024] like Figure 1 and Figure 4 As shown, the top of the collection tank 96 is opened into an arc-shaped surface at the position inside the card block 94, which facilitates dust and debris to smoothly enter the collection tank 96 along the arc-shaped surface, effectively improving the collection rate of the collection tank 96.

[0025] like Figure 1 and Figure 4 As shown, the rubber stopper 95 is shaped like a frustum, and the diameter of the top end of the rubber stopper 95 is smaller than the diameter of the bottom end, which can increase the friction when the rubber stopper 95 contacts the groove 93, thereby improving the stability of the rubber stopper 95.

[0026] Working Principle: In actual use, when the cold storage tank needs to provide emergency cooling for the air conditioning system, external water enters the tank 1 through the inlet pipe 2. As the cold storage tank continues to work, the temperature of the water inside the tank 1 will rise. The high temperature of the water will increase the pressure inside the tank 1. As the pressure inside the tank 1 gradually increases, when the internal air pressure exceeds the threshold set by the air pressure sensor 8, the cylinder 6 is automatically activated. The cylinder 6 drives the movable plate 5 to move upward. When the outer surface of the movable plate 5 is no longer in contact with the outer surface of the fixed plate 4, the gas inside the tank 1 is quickly discharged through the gap between the movable plate 5 and the fixed plate 4 due to the pressure difference between the top and bottom of the fixed plate 4. Then, it is discharged from the inside of the tank 1 through the exhaust port 92, thereby realizing the internal pressure regulation of the tank 1. It can automatically realize the internal pressure regulation of the cold storage tank, effectively improve the gas discharge rate, and ensure that the cold storage tank will not be damaged or expand due to excessive internal pressure, thus improving the protection of the cold storage tank.

[0027] Then, with prolonged use of the exhaust assembly 9, a large amount of dust and debris will accumulate inside the collection tank 96. First, remove the exhaust assembly 9 from the tank 1, then move the collection tank 96 downwards. The movement of the collection tank 96 causes the locking block 94 and the rubber plug 95 to move synchronously. As the collection tank 96 slowly moves, when the locking block 94 and the rubber plug 95 are no longer in contact with the locking slot 93, the collection tank 96 is removed, making it convenient to clean the collection tank 96. This simplifies the installation process of the collection tank 96, allows for quick disassembly and installation of the collection tank 96, facilitates thorough cleaning of the collection tank 96, and effectively improves the cleaning efficiency of the collection tank 96, thereby improving the maintenance efficiency of the collection tank 96.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
