[0034] In order to clearly understand the technical solution of the present application, a heat preservation device and a cold storage system provided by the present application will be described in detail below with reference to specific embodiments and drawings.

[0035] The terms used in the following examples are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0036] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "one embodiment," "some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0037] Example 1: This example provides a heat preservation device. Figure 1, which shows a schematic diagram of the overall structure of the heat preservation device. As can be seen from the figure, the heat preservation device mainly consists of three parts: a refrigerant storage tank 1, a constant temperature mechanism, and an anti-collapse mechanism. The refrigerant storage tank 1 is used to store refrigerant (such as water, carbon dioxide, etc.) delivered from other processes for subsequent use of the refrigerant. The refrigerant stored in the refrigerant storage tank 1 needs to be adjusted to a reasonable range at any time by the constant temperature mechanism so that the temperature of the refrigerant can meet the temperature required by the designated work station. In order to save space on the ground, the refrigerant storage tank 1 is usually placed in a foundation pit excavated on the ground. However, since the chloroprene rubber production plant is located on the bank of the Yellow River, the foundation pit may collapse after long-term use. For this reason, an anti-collapse mechanism is installed on the side of the refrigerant storage tank 1 to prevent the foundation pit from collapsing.

[0038] refer to Figure 3 and Figure 1 The top of the refrigerant storage tank 1 is respectively provided with a refrigerant inlet 2 and a refrigerant outlet 3; the top of the refrigerant storage tank 1 is also fixedly connected with a hook 4 by welding, and a traction device (such as a crane, etc.) completes the ascent or descent of the refrigerant storage tank 1 by pulling the hook 4; the surrounding side of the refrigerant storage tank 1 is provided with an anti-collapse mechanism, and the specific structure of the anti-collapse mechanism is as follows.

[0039] Combine Figure 1 、 Figure 2 ,in, Figure 3 A schematic diagram of the three-dimensional structure of the anti-collapse mechanism is shown. As can be seen from the figure, the anti-collapse mechanism includes a storage compartment, within which a refrigerant storage tank 1 is placed and adapted. The bottom edge of the storage compartment is used to support the refrigerant storage tank 1. As an optimization, multiple through-holes 5 are provided on the surface of the storage compartment. The through-holes 5 not only save material usage to a certain extent, but also ensure ventilation, allowing natural wind to initially cool the refrigerant storage tank 1. Baffles 6 are installed on each of the four sides of the refrigerant storage tank 1. Each baffle 6 is designed to form a snug fit with the adjacent sides of the foundation pit. As an optimization, wire mesh 7 is installed on baffles 6. The flexible shape of wire mesh 7 can adapt to the uneven pit sidewalls and various irregularly shaped rocks. A constant temperature mechanism is installed on the anti-collapse mechanism. This constant temperature mechanism is used to promptly cool the surface of the refrigerant storage tank 1, thereby indirectly maintaining a constant temperature for the refrigerant. The specific structure of the constant temperature mechanism is as follows.

[0040] refer to Figure 1 、 Figure 3 ,in, Figure 2What is shown is a schematic diagram of the partial installation structure of the constant temperature mechanism. As can be seen from the above figure, the constant temperature mechanism includes a liquid storage tank 8, which can be connected to the top of the refrigerant storage tank 1 in a detachable manner (such as bolt connection), and the liquid storage tank 8 is used to add liquids such as pure water or emulsion (the composition of the emulsion is usually composed of 95% pure water and 5% oil; the liquid in the liquid storage tank 8 is pumped in through other pump bodies, which will not be repeated here); a circulating water pump 9 is placed in the liquid storage tank 8, and the suction port of the circulating water pump 9 is connected to a liquid inlet conduit 10, and the discharge port of the circulating water pump 9 is connected to a liquid outlet conduit 11. A condensing pipe 12 is coiled around the side of the refrigerant storage tank 1 in a serpentine manner. A refrigerator is installed on the condensing pipe 12 (an existing product available on the market can be directly used, which is not shown in the figure). An outlet and an inlet are respectively formed at the two free ends of the condensing pipe 12. The outlet and the inlet of the condensing pipe 12 are respectively connected to the liquid inlet conduit 10 and the liquid outlet conduit 11 of the circulating water pump 9.

[0041] The general working principle of the thermal insulation device is as follows: First, a foundation pit is excavated at a designated work location (e.g., along the Yellow River). The baffles 6 of the anti-collapse mechanism are adapted to fit the surrounding side walls of the foundation pit. A crane or other traction equipment is used to transfer the anti-collapse mechanism into the foundation pit. When the baffles 6 of the anti-collapse mechanism fit the side walls of the foundation pit, they can also prevent minor collapse of the foundation pit and the fall of soil and falling rocks to a certain extent. Then, once the anti-collapse mechanism is in place in the foundation pit, the traction equipment is again used to transfer the refrigerant storage tank 1 into the storage compartment of the anti-collapse mechanism until the bottom of the refrigerant storage tank 1 contacts and fits with the bottom edge of the storage compartment. At this point, the storage compartment can restrict the movement of the refrigerant storage tank 1. Finally, the condensing pipe 12 is manually wound in a snake form on the outer surface of the refrigerant storage tank 1, and the liquid storage tank 8 is bolted to the top of the refrigerant storage tank 1, the outlet of the condensing pipe 12 is connected to the liquid inlet pipe 10, and the inlet of the condensing pipe 12 is connected to the liquid outlet pipe 11; at the same time, the liquid needs to be injected into the liquid storage tank 8 in advance, and then the circulating water pump 9 and the refrigerator are started. The refrigerated liquid in the condensing pipe 12 continuously cools the refrigerant storage tank 1 and the refrigerant medium during the flow, so that the refrigerant medium is kept at a low temperature state, thereby achieving the insulation effect (of course, in actual design, a temperature sensor can also be installed in the refrigerant storage tank 1 to accurately grasp the temperature of the refrigerant medium).

[0042] The present invention combines the refrigerant storage box 1, the constant temperature mechanism and the refrigerant medium together to cool the refrigerant medium and maintain it at different temperatures, thereby effectively solving the problem of keeping the refrigerant warm; and by combining it with the foundation pit, it can effectively save the usable space on the ground; and by combining it with the anti-collapse mechanism, it can effectively avoid slight landslides in the foundation pit and the falling of soil and rocks.

[0043] In order to facilitate the subsequent disassembly and assembly of the storage bin, this embodiment optimizes the anti-collapse mechanism. Figure 4 , Figure 4 What is shown is a schematic diagram of the partially exploded structure of the optimized storage bin, and the specific structure is as follows: the storage bin is composed of four enclosures 13, the bottom of a single enclosure 13 is bent inward and formed with a folded edge 14, and the four enclosures 13 are fitted together end to end to form a rectangular storage bin, and the four folded edges 14 together constitute the bottom edge of the storage bin for supporting the refrigerant storage box 1; a rectangular keel frame 15 is provided in the middle of the four enclosures 13, and the side walls of the keel frame 15 are fixedly connected to the single enclosure 13 on the adjacent side by bolts.

[0044] As a further optimization of the anti-collapse mechanism, continue to refer to Figure 4 Ground piles are formed at the bottom of each single-leaf enclosure 13, and the tips of the ground piles are used to be inserted into the bottom of the foundation pit. The advantages of providing ground piles are that, on the one hand, the ground piles can ensure that the storage bin can be more firmly fixed in the foundation pit, and on the other hand, the different depths of the ground piles inserted into the foundation pit ensure that there is a certain distance between the storage bin and the bottom of the foundation pit, so that when a small amount of water accumulates in the foundation pit, it can prevent the accumulated water from affecting the refrigerant storage tank 1.

[0045] In Example 2, as the accumulated water accumulates in the foundation pit, the water level will gradually exceed the ground pile and contact the refrigerant storage tank 1; in order to prevent the accumulated water from soaking and damaging the refrigerant storage tank 1, a drainage mechanism is further designed in this embodiment. Figure 5 , which shows a schematic diagram of the assembly structure of the drainage mechanism, the drainage mechanism is arranged on the anti-collapse mechanism; the specific structure of the drainage mechanism is as follows.

[0046] like Figure 5-6 As shown in, where Figure 6What is shown is a schematic diagram of the three-dimensional structure of the drainage mechanism. It can be seen from the above two figures that the drainage mechanism includes a bearing seat 16, which is fixedly connected to the baffle 6 on the adjacent side by welding; a water pump 17 is fixedly connected to the bearing seat 16 (the water pump 17 can directly use an existing product that can be purchased on the market, which will not be described in detail here), one end of the water pump 17 is formed with a water suction port, and the other end of the water pump 17 is formed with a water outlet; the water outlet is connected to a drainage pipe 18, and the free end of the drainage pipe 18 is placed outside the foundation pit; the driving source of the existing water pump 17 is mostly driven by a motor, but the defect of using a motor is that: although the motor can be waterproofed, there is still a risk of leakage when used for a long time. For this reason, the motor is replaced by an emulsion pump 19 in this embodiment (the structure and working principle of the emulsion pump 19 are existing technology, which will not be described in detail here); the emulsion The pump 19 is fixedly connected to the bearing seat 16 by a support rod, and the power shaft of the emulsion pump 19 is connected to the power shaft of the water pump 17 through a transmission belt; the emulsion pump 19 is provided with an emulsion outlet and an emulsion return port, and the emulsion enters the emulsion pump 19 through the emulsion return port, and then the emulsion is discharged from the emulsion outlet of the emulsion pump 19. By continuously circulating the emulsion, the power shaft on the emulsion pump 19 rotates and generates power; the emulsion return port is connected to a diversion pipe 20, and the other end of the diversion pipe 20 is connected to the liquid outlet conduit 11 (in this embodiment, the refrigerant in the refrigerant storage tank 1 is limited to emulsion); the emulsion outlet is connected to a return pipe 21, and the free end of the return pipe 21 is connected to the diversion pipe 20. A one-way valve 22 is installed on the return pipe 21, and the one-way valve 22 allows the emulsion to flow from the return pipe 21 to the diversion pipe 20. It is also limited that the water suction port of the water pump 17 is lower than the bottom of the refrigerant storage tank 1 .

[0047] The general working principle of the drainage mechanism is as follows: when the emulsion flows out of the liquid outlet conduit 11, a portion of the emulsion first enters the diversion pipe 20 and flows in the direction a1, and eventually enters the emulsion pump 19; the emulsion flowing out of the emulsion pump 19 enters the return pipe 21 and flows in the direction a2 until the emulsion converges into the diversion pipe 20; the emulsion continuously circulates within the emulsion pump 19, causing the power shaft of the emulsion pump 19 to rotate; the operating emulsion pump 19 drives the water pump 17 to remain in operation. Once the accumulated water in the foundation pit contacts the water inlet of the water pump 17, the water in the foundation pit enters the water inlet under the suction action of the water pump 17, thereby preventing the accumulated water from reaching the bottom of the refrigerant storage tank 1. The provision of the drainage mechanism in this embodiment not only prevents the refrigerant storage tank 1 from being damaged by accumulated water, but also effectively extends the service life of the drainage mechanism by replacing the traditional motor with the emulsion pump 19, thereby preventing the occurrence of leakage accidents.

[0048] During the use of the drainage mechanism, there is still a problem: although the accumulated water that is about to reach the bottom of the refrigerant storage tank 1 can be sucked out in time, as long as the emulsion circulates in the liquid outlet conduit 11, the emulsion pump 19 will always be in the started state regardless of whether the accumulated water is sucked out. In order to further solve the above problem, refer to Figure 7 The schematic diagram of the assembly structure of the optimized drainage mechanism is shown in the figure. It can be seen from the figure that the drainage mechanism also includes a cut-off unit, which is connected to the diversion pipe 20. The cut-off unit is used to conduct or block the flow of the emulsion in the diversion pipe 20; when the accumulated water rises to the bottom of the refrigerant storage tank 1 and contacts the water suction port of the water pump 17, the cut-off unit will conduct the pipe, and the emulsion will enter the emulsion pump 19 from the diversion pipe 20; and when the accumulated water is away from the refrigerant storage tank 1 or the water suction port of the water pump 17, the cut-off unit will block the diversion pipe 20, preventing the emulsion from entering the emulsion pump 19 from the diversion pipe 20; the more specific structure of the cut-off unit is as follows.

[0049] Combine Figure 7-8 ,in Figure 8 The figure shows a schematic diagram of the three-dimensional structure of the cut-off unit. As can be seen from the above two figures, the cut-off unit includes a flow control chamber 23, both ends of the flow control chamber 23 are connected to the guide pipe 20, the top of the flow control chamber 23 is fixedly connected to a suspension arm 24, and the free end of the suspension arm 24 is fixedly connected to the adjacent side wall of the storage bin; further combined with Figure 9 The exploded structure of the flow control chamber 23 and the plug plate 26 shown in the figure is schematically shown. A plug hole 25 is formed at the bottom of the flow control chamber 23, and the plug hole 25 is connected to the interior of the flow control chamber 23. The plug plate 26 can be slidably inserted into the plug hole 25 and block the inner cavity of the flow control chamber 23; a driving source is installed on the plug plate 26, and the driving source can be used to drive the plug plate 26 to move and block the inner cavity of the flow control chamber 23; this embodiment cites one implementation method of the driving source as follows (of course, the implementation method of the driving source is not limited to this implementation method).

[0050] Continue to see Figure 7-8The driving source includes a storage groove 27, which is fixedly connected to the baffle 6 on the adjacent side. A guide arm 28 is fixedly connected to one side of the storage groove 27. A slide groove 29 extending vertically is provided on the surface of the guide arm 28. A sliding seat 30 is slidably connected in the slide groove 29, and the sliding seat 30 is fixedly connected to the plug plate 26; a sliding frame 31 is slidably connected in the storage groove 27, and a sponge 32 is bonded to the middle part of the sliding frame 31. Two steel ropes 33 are bolted to the left and right sides of the sliding frame 31, and the other end of the steel rope 33 is fixedly connected to the adjacent end of the sliding seat 30; a first elastic component 34 (such as a spring, etc.) is fixedly connected to the sliding seat 30, and the other end of the first elastic component 34 is fixedly connected to the surface of the flow control cavity 23. It is also defined that when the first elastic component 34 is in a natural state, the unsoaked sponge 32 and the sliding frame 31 are placed on the top of the storage groove 27 ; at the same time, the top of the storage groove 27 is placed below the refrigerant storage tank 1 .

[0051] The working principle of the cut-off unit is as follows: first, when the accumulated water in the foundation pit gradually overflows the top of the storage tank 27 and contacts the sponge 32, as the sponge 32 absorbs more and more accumulated water, the weight of the sponge 32 gradually increases; until the weighted sponge 32 far exceeds the deformation force of the first elastic component 34, the sponge 32 at this time drives the sliding frame 31 and the wire rope 33 to move downward, thereby indirectly driving the sliding seat 30 and the plug plate 26 to move downward (along the c direction); then, when the plug plate 26 moves downward, the inner cavity of the flow control chamber 23 blocked by the plug plate 26 is gradually opened, and the emulsion can flow through the gap between the plug plate 26 and the inner cavity of the flow control chamber 23 along the b direction (as shown in FIG. Figure 10 (a schematic diagram of the emulsion flowing through the flow control chamber 23 after the conduction), so that the emulsion pump 19 drives the water pump 17 to start, and the water pump 17 lowers the water level in the refrigerant storage tank 1 until the accumulated water is sucked out; finally, the water in the sponge 32 needs to be removed by natural wind or manually. When the water in the sponge 32 disappears, the first elastic component 34 indirectly returns the sliding frame 31 and the sponge 32 to their original positions.

[0052] Example 3, as an optimization solution for Example 1 and Example 2, after the anti-collapse mechanism and the refrigerant storage tank 1 are transferred to the foundation pit, in order to prevent dust from entering the foundation pit and considering the safety hazards of people falling into the foundation pit, reference Figure 11 The sealing plate 35 installation structure diagram shown in FIG needs to be laid above the anti-collapse mechanism and the refrigerant storage tank 1.

[0053] Example 4: This embodiment provides a cold storage system, which includes the heat preservation device shown in Example 3. The cold storage system is further provided with multiple pushing devices on the basis of the heat preservation device, and each baffle 6 is provided with at least one pushing device; Figure 12, shows a schematic diagram of the assembly structure of the jacking device. As can be seen from the figure, in this embodiment, two jacking devices are installed on corresponding sides of a single baffle 6, and the jacking devices are connected to the surface of the refrigerant storage tank 1. When the collapsed foundation pit sidewall squeezes the adjacent baffle 6, the anti-collapse mechanism can address mild collapse of the foundation pit. If the foundation pit experiences a more serious collapse, the jacking device is required to provide auxiliary support for the adjacent baffle 6, thereby to a certain extent enhancing the baffle 6's ability to resist collapsed soil and gravel. The specific structure of the jacking device is as follows.

[0054] Further integration Figure 13 , shows a schematic diagram of the installation structure of a single pushing device. As can be seen from the figure, a buffer groove 36 is opened on the surface of the refrigerant storage box 1, a slide 37 is fixedly connected to the top wall of the buffer groove 36, and a pushing seat 38 is slidably connected to the slide 37. The flange part of the pushing seat 38 is movable through the storage bin and opposite to the baffle 6 on the adjacent side; further combined Figure 14 , shows a schematic diagram of the assembly structure of the rotating unit. As can be seen from the figure, the rotating unit includes a fixed support 39 and a flip support 40. The fixed support 39 is fixedly connected to the surface of the storage bin, and the flip support 40 is fixedly connected to the corresponding baffle 6. The flip support 40 and the fixed support 39 are rotatably connected by a pin. A second elastic component 41 (such as a spring, etc.) is connected to the baffle 6, and the other end of the second elastic component 41 is connected to the fixed support 39. When the side wall of the foundation pit collapses more seriously, the baffle 6 on the corresponding side will slightly flip and tilt under the pressure of soil and gravel. The tilted baffle 6 presses the push seat 38 to move toward the buffer groove 36 until the push seat 38 contacts the side wall of the buffer groove 36. At this time, the push seat 38 forms a reaction force on the baffle 6, thereby assisting the baffle 6 in blocking the side wall of the foundation pit.

[0055] In order to facilitate the staff on duty or working to promptly detect the collapse of the foundation pit, this embodiment optimizes the pushing device as follows: Figure 15 , showing a schematic diagram of the optimized jacking mechanism's three-dimensional structure, shows a groove 42 formed on the bottom of the jacking seat 38. A sealed box 43 is fixedly connected to the slide 37, slidingly connected to the groove 42. The sealed box 43 is filled with an odorizing agent (off-the-shelf products can be used), and a plastic film 44 is provided on one side of the sealed box 43. A sharp needle 45 is installed in the groove 42, facing the plastic film 44. During use, as the jacking seat 38 moves into the buffer tank 36, the sharp needle 45 gradually contacts and punctures the plastic film 44. The odorizing agent then flows out of the puncture and into the surrounding environment. Upon smelling the odor, workers can promptly identify the extent of the foundation pit collapse, allowing for prompt and appropriate follow-up measures.

[0056] In order to ensure that the staff can accurately determine the approximate location of the collapse, this embodiment further optimizes the pushing device; Figure 16 , which shows a schematic diagram of the installation structure of the indicating unit. It can be seen from the figure that the indicating unit is transmission-connected to the push seat 38; the more specific structure of the indicating unit is as follows.

[0057] Specifically, the indicating unit includes a gear 46, the central axis of which is rotatably connected to the slide 37. A toothed plate 47 is fixedly connected to the bottom of the push seat 38, and the toothed plate 47 meshes with the gear 46. A roller 48 is concentrically fixedly connected to the central axis, and a tensioning pulley 49 is rotatably connected to the outer wall of the storage bin. A hole 50 is formed on the side of the sealing plate 35 adjacent to the single baffle 6. The bottom of the hole 50 is connected to a cover 51 for blocking the hole 50 via a torsion spring. A pull wire 52 is wound around the roller 48, which passes around the tensioning pulley 49 and is connected to the cover 51.
