[0003] The constant temperature control device usually includes components such as a temperature sensor, a controller, a heater and a refrigerator. The temperature sensor is used to monitor the temperature in the container and transmit the real-time temperature information to the controller. The controller controls the heater and refrigerator to adjust the temperature in the container. When the temperature in the container exceeds the set upper limit temperature, the controller will start the refrigerator to lower the temperature.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1

[0031] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a constant temperature control device for an energy storage system container, including a container body 100, a monitoring component 200, and a temperature control component 300; wherein, a receiving space 101 with openings at both ends is arranged inside the container body 100, and a placement rack 102 for placing energy storage batteries is arranged in the receiving space 101; the monitoring component 200 is arranged in the receiving space 101, and is used to monitor the state of the energy storage batteries placed in the receiving space 101; the temperature control component 300 is used to adjust the internal temperature of the receiving space 101, and includes a primary temperature control unit 301 that uses groundwater resources to adjust the temperature of the container body 100 and the internal receiving space 101, and a secondary temperature control unit 302 that uses refrigeration and heating in coordination.

[0032] Specifically, a partition 103 is provided in the accommodating space 101, and two partitions 104 are provided on the partition 103 and are vertically fixed to the inner wall of the container body 100. The two partitions 104 and the inner wall of the container enclose a monitoring equipment cavity 104a for installing the monitoring component 200. The energy storage battery and the mounting rack 102 are arranged in the accommodating space 101 and are located on one side of the space opposite to the two partitions 104, and the energy storage battery is placed on the mounting rack 102.

[0033] As a further improvement, the monitoring component 200 includes a temperature and humidity sensor for monitoring the temperature and humidity inside the accommodating space 101, an infrared detector for monitoring the temperature of the energy storage battery in the accommodating space 101, and a smoke alarm.

[0034] As a further improvement, the first-level temperature control unit 301 includes a water pump 301a, a protective box 301b, and a spiral water pipe 301c; wherein, the water pump 301a is arranged in the protective box 301b, and the protective box 301b is a hollow box body, which ensures that groundwater can enter the protective box 301b and be extracted by the water pump 301a. At the same time, the hollow box body can also play a role in blocking weeds and other water garbage to prevent garbage from being pumped into the water pump 301a and causing pump damage.

The groundwater after participating in the heat exchange flows back to the underground. The water temperature of the groundwater is usually warm in winter and cool in summer. It can provide heating for the container in winter and cooling for the container in summer, thereby meeting the constant temperature requirement of the accommodating space 101 in the container body 100.

[0036] As a further improvement, the secondary temperature control unit 302 includes a blowing member 302a arranged in the accommodating space 101, and an exhaust member 302b arranged on one side of the outside of the container body 100, and the blowing member 302a is connected to the exhaust member 302b. Specifically, the blowing member 302a is an indoor unit of the air conditioner, and the exhaust member 302b is an outdoor unit of the air conditioner.

[0037] In summary, when the monitoring component 200 sets a first-level preset detection value, a second-level preset detection value, and a third-level preset detection value for the temperature detection in the accommodating space 101, when the detection value is between the first-level preset detection value and the second-level preset detection value, the first-level temperature control unit 301 is started, and the groundwater is pumped, and the groundwater circulates along the water pipeline on the surface of the container body 100 to adjust the temperature in the accommodating space 101 and cool down the inside of the accommodating space 101. When the temperature detection value in the accommodating space 101 is higher than the second-level preset detection value, the second-level temperature control unit 302 is started to adjust the temperature in the accommodating space 101 and cool down the inside of the accommodating space 101. When the temperature detection value in the accommodating space 101 is higher than the third-level preset detection value, the first-level temperature control unit 301 and the second-level temperature control unit 302 are started at the same time to adjust the temperature in the accommodating space 101 and cool down the inside of the accommodating space 101.

[0038] Compared with the traditional constant temperature control device, the present invention introduces a primary temperature control unit 301, utilizes natural resources for temperature regulation, and activates different temperature regulation schemes based on different temperature detection values, thereby maximally saving the power consumption of the energy storage system by the constant temperature control device.

[0039] Example 2

[0040] Reference Figure 1 to Figure 6, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the primary temperature control unit 301 also includes a leakage detection module, which is used to monitor the operation of the spiral water pipeline 301c to prevent the spiral water pipeline 301c from rupturing and leaking; the leakage detection module includes a flow rate sensor for detecting the flow rate of the fluid in the spiral water pipeline 301c, a timer for detecting the total working time of the spiral water pipeline 301c, and a temperature and pressure sensor for detecting the temperature and pressure of the internal fluid of the spiral water pipeline 301c, wherein at least two temperature and pressure sensors are provided, and the two temperature and pressure sensors are respectively provided at the water inlet end and the water outlet end of the spiral water pipeline 301c.

[0041] As a further improvement, the mounting rack 102 is an electric mobile rack that can extend from the open end of the accommodating space 101 to the outside of the container body 100. The mounting rack 102 is electrically connected to the leakage detection module to promptly move the energy storage battery on the mounting rack 102 out of the container body 100 when the leakage detection module detects a leak in the spiral water pipeline 301c.

[0042] Specifically, the placement frame 102 includes two symmetrically arranged electric shift screws 102a, the electric shift screws 102a are threadedly connected with shift nuts 102b, the shift nuts 102b are fixedly connected with a bottom placement plate 102c, and the bottom placement plate 102c is connected to a plurality of upper placement plates 102d via telescopic rods 102e. The bottom placement plate 102c and the upper placement plate 102d are used for storing energy storage batteries.

[0043] As a further improvement, the leakage detection module further includes an alarm for sounding an alarm when the spiral water pipeline 301c is broken and leaks, and a controller for controlling the opening and closing of the valve on the spiral water pipeline 301c.

[0044] Specifically, the controller and the alarm are electrically connected to the flow rate sensor, the timer, the temperature and pressure sensor, and the mounting rack 102, and the working principle of the controller based on the flow rate sensor, the timer, the temperature and pressure sensor, and the mounting rack 102 is:

[0045] Calculate the actual leakage coefficient of the spiral water pipeline based on the flow rate sensor, timer, and temperature and pressure sensor;

[0046]

[0047] In the formula, is the actual leakage coefficient of the spiral water pipe 301c; θ i is the detection value of the flow velocity sensor for the i-th detection; t α is the detection value of the timer; t1 is the detection cycle of the flow velocity sensor, and the flow velocity is detected once every t1;

[0048] for The value of T is rounded; j is the detection value of the temperature sensor for the jth detection;

[0051] Furthermore, the controller compares the actual leakage coefficient of the spiral water pipeline 301c with the preset leakage coefficient of the spiral water pipeline 301c. If the actual leakage coefficient of the spiral water pipeline 301c is greater than the preset leakage coefficient of the spiral water pipeline 301c, the controller controls the alarm to sound, and at the same time controls the placement rack 102 to start, and moves the energy storage battery on the placement rack 102 out of the container body 100 in time.

[0052] The remaining structures are the same as those of Example 1.

[0053] Example 3

[0054] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it also includes a closing component 400. There are two groups of closing components 400 with the same structure. The two groups of closing components 400 are respectively arranged at the two end openings of the container body 100 corresponding to the accommodating space 101, and are used to close the accommodating space 101; the closing component 400 includes a door 401, and a driving unit 402. One end of the driving unit 402 is connected to the container body 100, and the other end of the driving unit 402 is connected to the door 401, and is used to control the opening and closing of the door 401.

[0056] As a further improvement, the drive unit 402 also includes a guide bar 402e arranged along the height direction of the box door 401, and a sleeve plate 402f slidably matched with the guide bar 402e; wherein, one end of the sleeve plate 402f is hinged to the top plate at the corresponding opening of the container body 100, and the guide bar 402e is arranged on the side of the box door 401 that fits the accommodating space 101.

[0057] The remaining structure is the same as that of Example 2.

[0058] Example 4

[0059] Reference Figure 1 to Figure 6 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: the device also includes a fire extinguishing component 500, which is used to promptly extinguish the open fire when the energy storage battery in the accommodating space 101 catches fire. The fire extinguishing component 500 includes an air chamber 501 for storing carbon dioxide, a powder chamber 502 for storing fire extinguishing dry powder, a nozzle 503 for extracting carbon dioxide and fire extinguishing dry powder and spraying them into the accommodating space 101, a first connecting pipe 504 connecting the nozzle 503 and the air chamber 501, and a second connecting pipe 505 connecting the nozzle 503 and the powder chamber 502; wherein, an air pump 506 is provided on the first connecting pipe 504, and the air pump 506 is electrically connected to the smoke alarm; a negative pressure fan 507 is provided in the powder chamber 502, which can assist in extracting the fire extinguishing dry powder in the powder chamber 502.

[0060] Specifically, an electric nozzle adjusting screw 508 is provided on the top wall of the accommodating space 101, and a nozzle adjusting nut 509 is threadedly connected to the electric nozzle adjusting screw 508, and a nozzle connecting rod 510 is fixedly connected to the nozzle adjusting nut 509, and a nozzle is fixedly connected to the nozzle connecting rod 510, and the nozzle inlet end is connected to the first connecting pipe 504 through a hose, and an air pump 506 is provided on the first connecting pipe 504, and the other end of the first connecting pipe 504 is connected to the air outlet port of the air chamber 501, and the first connecting pipe 504 is connected to the second connecting pipe 505, and the second connecting pipe 505 is connected to the powder outlet port of the powder chamber 502, and both the first connecting pipe 504 and the second connecting pipe 505 are provided with a one-way valve.

[0061] As a further improvement, the powder chamber 502 includes a fire extinguishing powder storage chamber 502a and a powder feeding chamber 502b. An electric auger 511 is rotatably connected in the fire extinguishing powder storage chamber 502a. The outlet end of the electric auger 511 is communicated with the powder feeding chamber 502b. An electric disc net 512 and a negative pressure fan 507 are rotatably connected in the powder feeding chamber 502b.

[0062] As a further improvement, the front end of the nozzle 503 is provided with a gate 513 slidably connected to the container body 100, and a buffer elastic member 514 is fixedly connected between the gate 513 and the inner wall of the container body 100. A plurality of exhaust fans 515 are arranged on the top wall of the accommodating space 101, and a guide plate 516 is provided at the air suction port of the exhaust fan 515. A guide connecting rod 517 is slidably connected up and down in the guide plate 516, and a compression elastic member 518 is sleeved on the guide connecting rod 517. A sliding plate 519 is fixedly connected to the guide connecting rod 517, and a pull rope 520 is fixedly connected to the sliding plate 519. The end of the pull rope 520 away from the exhaust fan 515 is fixedly connected to the gate 513.

[0063] In summary, when the temperature in the accommodating space 101 rises to cause the air therein to expand, the sliding plate 519 moves upward under the action of air pressure, thereby compressing the compression elastic member 518, and the sliding plate 519 moves out of the air suction port of the exhaust fan 515, and the expanded gas is discharged upward, while driving the exhaust fan 515 to rotate, thereby accelerating the gas discharge efficiency and allowing the hot air in the accommodating space 101 to be drawn out.

[0064] When a fire occurs, such as when the energy storage battery is ignited due to high temperature, the expansion rate of the gas inside the accommodating space 101 is accelerated, and the sliding plate 519 can be moved out of the suction port of the exhaust fan 515 more quickly, and the smoke is drawn out under the rotation of the exhaust fan 515; at the same time, the sliding plate 519 drives the pull rope 520 to move, and the pull rope 520 pulls the gate 513 to open it.

[0065] At the same time, when the smoke alarm detects smoke, the fire extinguishing assembly 500 is activated, the electric nozzle adjustment screw 508 rotates to drive the nozzle adjustment nut 509 to move under the action of the thread, and the nozzle adjustment nut 509 moves to drive the nozzle to move outward and extend into the accommodating space 101, and at the same time, the air pump 506 is started to output the carbon dioxide in the air chamber 501 to the nozzle, and at the same time, the electric auger 511 rotates to input the fire extinguishing dry powder in the fire extinguishing powder storage chamber 502a into the powder supply chamber 502b, and then the negative pressure fan 507 rotates to input the powder input into the powder supply chamber 502b into the second connecting pipe 505, and then enters the first connecting pipe 504 through the second connecting pipe 505, and finally sprays out from the nozzle. During the operation of the negative pressure fan 507, the electric disc net 512 rotates. Thereby, the effect of the negative pressure fan 507 is enhanced. If the dry powder input into the powder supply chamber 502b is large, the excess dry powder will pass through the electric disc net 512 and fall into the fire extinguishing powder storage chamber 502a.

[0066] The remaining structures are the same as those of Example 4.
