Abstract
Description
Technical Field
[0001] This invention relates to the field of energy storage tank technology, and more specifically, to an energy storage tank with a built-in herringbone-shaped water distributor. Background Technology
[0002] In the field of energy storage and environmental control, energy storage tanks, as key equipment, are not only widely used in various energy storage scenarios such as solar water heating systems, industrial waste heat recovery, and pumped storage power stations, but also play an important role in applications such as air conditioning, air humidification, ventilation, and airflow shielding. Especially in places where air quality needs to be controlled, pollutants need to be removed, or specific environmental conditions need to be maintained, such as industrial production workshops, data centers, hospital operating rooms, and laboratories, the design and operating efficiency of energy storage tanks and their related systems are particularly important.
[0003] Currently, thermal stratification (such as high temperature at the top and low temperature at the bottom) is prone to occur inside energy storage tanks, which leads to reduced heat exchange efficiency and may even cause local overheating and damage to the equipment. Traditional temperature detection solutions mostly use fixed multi-point sensor arrays, which can cover the entire tank but are expensive. Moreover, the sensors are susceptible to corrosion or scaling due to long-term immersion, and the maintenance cycle is short. Therefore, we propose an energy storage tank with a built-in herringbone-shaped water distributor. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy storage tank with a built-in fishbone-shaped water distributor to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy storage tank with a built-in fishbone-shaped water distributor, comprising an energy storage tank body, temperature detection components being provided on the upper, middle and lower parts of the outer side of the energy storage tank body, a fishbone-shaped water distributor body being provided inside the energy storage tank body, a random detection component being provided on the top of the energy storage tank body, a fixing plate being installed inside the energy storage tank body, an mounting plate being installed on the top of the fixing plate, a waterproof cover being installed at the bottom of the mounting plate, a waterproof motor being installed inside the waterproof cover, a stirring paddle being connected to the power drive end of the waterproof motor, and a control device being installed on the outer side of the energy storage tank body; The temperature detection component includes a water inlet pipe installed on one side of the energy storage tank body. The water inlet pipe is equipped with a control valve. An installation cylinder is installed at one end of the water inlet pipe. The installation cylinder has two chambers arranged from top to bottom. A water inlet hole is provided inside the water inlet pipe between chambers one and two. A pressure sensor is installed inside the installation cylinder near the water inlet hole. A float ball is installed inside chamber two. A counterweight sand is provided at the bottom of the float ball. A float plate is provided outside the float ball. A drain pipe with a control valve is provided at the bottom of the installation cylinder. A temperature detector is installed outside the water inlet pipe. The detection end of the temperature detector is located inside chamber one.
[0006] Preferably, the water inlet of the fishbone-shaped water distributor body is located outside the energy storage tank body, and the agitator is rotatably connected to the top of the mounting plate.
[0007] Preferably, the water inlet pipe is connected to the position of chamber one, and chamber one and chamber two are connected through the water inlet hole.
[0008] Preferably, the counterweight sand is lightweight and is used to balance the buoy and float.
[0009] Preferably, the random detection component includes a mounting base installed on the top of the energy storage tank body, and an electromagnet is installed at the top of the interior of the mounting base.
[0010] Preferably, the electromagnet has an iron ball magnetically attracted to its bottom, a guide post is installed at the center of the bottom of the mounting base, and several sets of guide blocks of different heights are provided at the bottom of the mounting base.
[0011] Preferably, the mounting base has three grooves, namely groove one, groove two, and groove three, which are adapted to fit the iron ball. Pressure sensor two is installed inside each of the three grooves.
[0012] The technical effects and advantages of this invention are as follows: In use, this invention uses an electromagnet to drive an iron ball to randomly fall into different grooves, triggering the temperature detection component at the corresponding position. Combined with the linkage design of the float and pressure sensor, physical isolation between chamber one and chamber two is achieved during detection. This innovative design effectively avoids the problems of medium corrosion and scaling caused by long-term immersion of traditional fixed sensors. At the same time, by isolating the sampling, it eliminates the thermal conduction interference between the inlet pipe and the tank wall, ensuring that the detected fluid is a fully mixed mid-section sample and reducing temperature measurement errors.
[0013] When in use, this invention addresses the problem of decreased heat exchange efficiency caused by thermal stratification inside the energy storage tank. When a temperature difference is detected, the control device immediately activates the stirring paddle to mix the fluid, breaking up the thermal stratification and thereby improving heat exchange efficiency. At the same time, the stirring paddle operates for ≤2 minutes at a time and is only activated when significant thermal stratification is detected, reducing energy consumption and equipment wear rate to 0%, and significantly extending the service life of the energy storage tank.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] As attached Figures 1-5 The energy storage tank shown includes an energy storage tank body 1. Temperature detection components 2 are provided on the upper, middle and lower parts of the outer side of the energy storage tank body 1. A fishbone-shaped water distributor body 3 is provided inside the energy storage tank body 1. The water inlet end of the fishbone-shaped water distributor body 3 is located outside the energy storage tank body 1. A random detection component 4 is provided on the top of the energy storage tank body 1. A fixing plate 5 is installed inside the energy storage tank body 1. An mounting plate 6 is installed on the top of the fixing plate 5. A waterproof cover 7 is installed at the bottom of the mounting plate 6. A waterproof motor 8 is installed inside the waterproof cover 7. The power drive end of the waterproof motor 8 is connected to a stirring paddle 9. The stirring paddle 9 is rotatably connected to the top of the mounting plate 6. A control device 10 is installed on the outer side of the energy storage tank body 1. Several sets of temperature detection components 2 are set up, located at the top, middle and bottom of the energy storage tank body 1 respectively. The water temperature at a certain location can be randomly detected by the random drop of the random detection component 4. The energy storage tank body 1 serves as the core container and stores the heat exchange medium inside. The water inlet of the fishbone-shaped water distributor body 3 is connected to an external heat source or cold source. The fluid is evenly distributed into the energy storage tank body 1 through a multi-branch structure, which enhances the heat exchange efficiency. The stirring paddle 9 is driven by a waterproof motor 8 and is used to break up the thermal stratification inside the tank and improve the temperature uniformity. The control device 10 can receive temperature detection data and control the water flow of the water distributor, the start and stop of the stirring paddle 9 and the random detection logic. Temperature detection component 2 includes a water inlet pipe 21 installed on one side of the energy storage tank body 1. The water inlet pipe 21 is equipped with a control valve. An installation cylinder 22 is installed at one end of the water inlet pipe 21. The installation cylinder 22 has a first chamber 23 and a second chamber 24 arranged sequentially from top to bottom. A water inlet hole 25 is provided inside the water inlet pipe 21 between the first chamber 23 and the second chamber 24. The water inlet pipe 21 is connected to the first chamber 23. The first chamber 23 and the second chamber 24 are connected through the water inlet hole 25. The installation cylinder 22... Pressure sensor 26 is installed inside the chamber 24 and near the inlet 25. A float 27 is installed inside the chamber 24. A counterweight sand 28 is installed at the bottom of the float 27. A float plate 29 is installed outside the float 27. The counterweight sand 28 is light in volume and is used to balance the float 27 and the float plate 29. A drain pipe 210 with a control valve is installed at the bottom of the mounting cylinder 22. A temperature detector 211 is installed outside the inlet pipe 21. The detection end of the temperature detector 211 is located inside the chamber 23. When one of the temperature detection components 2 is activated by the random detection component 4, the control valve of the inlet pipe 21 opens, and water enters the second chamber 24 through the inlet hole 25 until the float 27 blocks the inlet hole 25. When the float plate 29 presses against the pressure sensor 26, the temperature detector 211 is activated. The temperature detector 211 detects the temperature of the water source in the first chamber 23. The counterweight sand 28 is light and does not affect the floating of the float 27. After detection, the control valve of the drain pipe 210 is opened to drain the water in the installation cylinder 22. The pressure sensor 26 is set with a threshold pressure, such as 0.5N. It is only triggered when the pressure of the float plate 29 reaches the threshold to avoid false alarms. The detection time of the temperature detector 211 is ≤5 seconds to reduce the impact of heat exchange on the results. The random detection component 4 includes a mounting base 41 installed on the top of the energy storage tank body 1. An electromagnet 42 is installed at the top inside the mounting base 41, and an iron ball 43 is magnetically attracted to the bottom of the electromagnet 42. A guide post 44 is installed at the center of the bottom inside the mounting base 41. Several sets of guide blocks 45 of different heights are provided at the bottom inside the mounting base 41. The mounting base 41 has groove 1 46, groove 2 47 and groove 3 48 respectively. Grooves 1 46, groove 2 47 and groove 3 48 are all adapted to the iron ball 43. Pressure sensor 2 49 is provided inside groove 1 46, groove 2 47 and groove 3 48. Several sets of guide blocks 45 of varying heights facilitate the flow of iron balls 43. Pressure sensors 49 are installed in groove 1 46, groove 2 47 and groove 3 48, respectively, corresponding to temperature detection components 2 installed in the upper, middle and lower parts. Random detection component 4 releases iron balls 43 through electromagnet 42 and guides them into different grooves using guide blocks 45, triggering temperature detection at the corresponding positions.
[0022] Working principle of this invention: After water enters the energy storage tank body 1 through the fishbone-shaped water distributor body 3, when temperature detection is required, the random detection component 4 is activated, and the iron ball 43 falls into the corresponding groove (such as groove 47), triggering the temperature detection component 2 in the middle. At this time, the control device 10 opens the control valve of the water inlet pipe 21 of the temperature detection component 2 in the middle, and the external fluid enters the first chamber 23 through the water inlet pipe 21. The fluid flows into the second chamber 24 through the water inlet hole 25. The float 27 rises with the water level, and the float plate 29 gradually approaches the pressure sensor 26. When the float 27 completely blocks the water inlet hole 25, the water level stops rising. When the float plate 29 rises, it presses against the pressure sensor 26, generating a trigger signal. Upon receiving the signal, the control device 10 activates the temperature detector 211 to detect the fluid temperature inside chamber 23 (at this time, chamber 23 and chamber 24 are isolated by the float ball 27 through the water inlet 25, and the temperature is stable). After detection, the control device 10 opens the drain pipe 210 control valve, the fluid in chamber 24 is discharged, the float ball 27 falls back to the bottom, and the system resets. Since the inlet pipe is in contact with the tank wall, the fluid temperature is affected by environmental or tank conduction. Therefore, the latter part of the water flow is sampled for detection to improve detection quality. When the electromagnet 42 is energized, it attracts the iron ball 43 to the top. The guide blocks 45 are arranged in a staggered pattern to form multiple potential paths. The iron ball 43 falls freely and, affected by the collision of the guide blocks 45, rolls towards groove 1 46, groove 2 47 or groove 3 48 in a probabilistic path. The edges of the grooves are rounded to avoid the iron ball 43 getting stuck. When random detection reveals an excessive temperature gradient inside the tank, the control device 10 starts the waterproof motor 8 to drive the stirring paddle 9 to rotate and mix the fluid. The stirring paddle 9 is only started when significant thermal stratification is detected, and each run takes ≤2 minutes to avoid continuous energy consumption. This device triggers a random detection every 30 minutes (adjustable according to user needs). If the temperature at the same location is abnormal twice in a row (e.g., the temperature in the middle is >90℃), an alarm is triggered and the water distributor is suspended. The water flow rate of the water distributor is adjusted according to historical data (e.g., the flow rate is increased when the temperature in the middle is low), or the start / stop threshold of the stirring paddle 9 is adjusted.
