Description

Technical Field

[0001] This utility model relates to the field of floor heating technology, specifically a replaceable floor heating structure. Background Technology

[0002] In recent years, my country's cold chain has entered a stage of explosive growth, with the development of cold storage and frozen warehouses being particularly rapid. They can effectively extend the shelf life of food, ensure food quality, promote food circulation, thereby improving the flexibility and stability of market supply, reduce losses and improve economic benefits for food producers and sellers, meet the low-temperature storage and transportation needs of special fields, and reduce energy consumption and carbon emissions through energy-saving and environmental protection measures.

[0003] Due to the frequent movement of goods in and out of cold storage facilities, cold air loss is significant, particularly at the floor level around the cold storage doors. Currently, heating components, such as heating wires, are embedded in the cold storage floor. The heat generated can prevent large-scale cold air leakage when the insulated doors are open. However, conventional cold storage floor heating wires are usually pre-embedded in the concrete floor, which makes replacement inconvenient and costly if the heating wires malfunction. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a replaceable floor heating structure to solve the technical problem that the current conventional construction process of cold storage floor heating wires is usually carried out by pre-embedding them in the concrete floor, which leads to the inconvenience and high cost of replacing the heating wires when they fail.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a replaceable floor heating structure is designed, including a heating threshold. The top of the heating threshold is detachably connected to a cover plate by fixing bolts. A galvanized conduit is provided on the inner side of the heating threshold. The galvanized conduit is movably connected to a control box installed on one side inside the heating threshold. A heating wire is threaded through the inner side of the galvanized conduit. Positioning strips are provided on both the left and right outer walls of the heating threshold. The positioning strips are inserted into the positioning grooves opened on the side walls of the threshold body. The heating threshold is vertically slidably connected to the threshold bodies on the left and right sides.

[0006] In this solution, the heating wire in the internal galvanized conduit can be replaced simply by opening the cover plate, without having to chisel the ground. This enables modular replacement of the heating components, reducing on-site workload and installation pollution. It is practical, reliable, and easy to use. Furthermore, the entire heating threshold is made of aluminum, which has good elasticity, corrosion resistance, and low-temperature resistance, reducing limitations and expanding the scope of application.

[0007] Preferably, the inner bottom of the heating threshold has two grooves, and the inner sides of the two grooves are slidably connected with a rod, one end of which penetrates the outer wall of the heating threshold.

[0008] In practical applications, the insertion rod extends out of the heating threshold and then inserts into the pre-drilled hole in the foundation, thereby improving the stability of the heating threshold.

[0009] Preferably, two locking blocks are fixedly connected to the top of the insertion rod, the galvanized conduit is located between the locking blocks and the insertion rod, and several equidistant protrusions are opened on the surface of the two insertion rods on opposite sides, the protrusions meshing with gears.

[0010] In practical applications, the locking block also limits and constrains the galvanized conduit during the sliding process of the insertion rod, thereby improving the stability of the galvanized conduit.

[0011] Preferably, the gear is rotatably connected to the bottom surface of the heating threshold between the two insert rods, and a fixing block is fixedly connected to the top of the gear, and a crossbar is fixedly connected to the top of the fixing block.

[0012] In practical applications, the lateral sliding of the two rods is controlled by gears, and the gears are controlled to rotate by the crossbar. During the rotation of the gears, they have a damping effect, which can prevent them from rotating freely.

[0013] Preferably, the inner sidewalls of the heating threshold corresponding to the horizontal height of the crossbar are provided with arc-shaped grooves, and the height of the arc-shaped grooves is consistent with the thickness of the crossbar.

[0014] In practical applications, when the crossbar rotates, both ends of it enter the arc-shaped groove. Since the internal height of the arc-shaped groove is the same as the thickness of the crossbar, there will be a frictional damping effect when the crossbar enters the arc-shaped groove, which ensures the stability of the crossbar.

[0015] Preferably, the fixing bolts on the surface of the cover plate are installed inside the groove on the surface of the cover plate, and the top edge of the heating threshold body directly below the fixing bolts is provided with bolt holes of corresponding size. The top surface of the heating threshold above the arc groove is provided with two bolt holes, which are connected to the arc groove.

[0016] In practical applications, when the crossbar reaches the center of the arc groove, it can be clamped in the center by the fixing bolts screwed into the bolt holes on both sides, thus preventing it from coming out of the arc groove again and ensuring the stability of the insertion rod and the galvanized conduit.

[0017] Preferably, four support blocks are fixedly connected to the inner bottom of the heating threshold, a heat insulation layer is provided at the bottom inner side of the heating threshold, a pressure-resistant layer is provided at the bottom of the heating threshold, and the threshold body and the front and rear sides of the threshold body are foundations.

[0018] In practical applications, the insulation layer can reduce the downward movement of heat and has a better effect on blocking cold air from above, while the compressive layer can effectively distribute the ground load, reduce local deformation, and provide some room for movement when the ground subsides.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model, by placing the galvanized conduit inside an independent heating threshold, allows for the replacement of the heating wire inside the galvanized conduit simply by opening the cover plate, without the need to chisel through the ground. This achieves modular replacement of the heating components, reducing on-site workload and installation pollution. It is practical, reliable, and easy to use. Furthermore, the entire heating threshold is made of aluminum, possessing good elasticity, corrosion resistance, and low-temperature resistance, reducing limitations and expanding the scope of application.

[0021] 2. This utility model, by setting up a plug rod and a locking block, allows the plug rod to extend out of the heated threshold and insert into a pre-drilled hole in the inner wall of the foundation, while the locking block limits and constrains the galvanized conduit. This improves the stability of the entire threshold body and the galvanized conduit, reduces the impact of vibrations caused by frequent cargo entry on the threshold body, and ensures the stable operation of the equipment.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: A replaceable floor heating structure, see [link / reference] Figures 1 to 5 The heating threshold 1 is detachably connected to a cover plate 2 via a fixing bolt 201. Four support blocks 4 are fixedly connected to the inner bottom of the heating threshold 1. The support blocks 4 can support and bear the load from below after the cover plate 2 is installed, effectively distributing the load and improving the compressive strength of the cover plate 2. In order to improve the overall compressive strength of the heating threshold 1, it can use aluminum-magnesium alloy instead of pure aluminum material, effectively improving its resistance to deformation while maintaining lightweight.

[0030] It is worth mentioning that the bottom of the heated threshold 1 is provided with a pressure-resistant layer 14. This pressure-resistant layer 14 can be a glass fiber reinforced nylon layer. Utilizing its high elastic modulus, it can effectively disperse the ground load, reduce local deformation, and provide a certain amount of movement space when the ground sinks. This provides a certain buffer movement space for the threshold body 101 and the heated threshold 1. Combined with the deformation resistance of its own aluminum-magnesium alloy material, even if the ground sinks and deforms slightly, it will not pop out of the ground, but will instead squeeze the pressure-resistant layer 14 downward.

[0031] Specifically, such as Figure 2 and Figure 4 As shown, the fixing bolts 201 on the surface of the cover plate 2 are installed inside the groove on the surface of the cover plate 2, and the top edge of the heating threshold 1 directly below the fixing bolts 201 is provided with bolt holes 8 of corresponding size. During installation, the cover plate 2 is first placed on the top of the heating threshold 1, and then the fixing bolts 201 are screwed into the groove at the top of the cover plate 2. The fixing bolts 201 will then enter the bolt holes 8, thereby installing the cover plate 2 and the heating threshold 1 together. The same principle applies when disassembling; simply unscrew the fixing bolts 201.

[0032] Specifically, such as Figure 4 As shown, a galvanized conduit 3 is provided on the inner side of the heating threshold 1. The galvanized conduit 3 is movably connected to a control box 301 installed on one side inside the heating threshold 1. The control box 301 is connected to an external power source via wires to ensure a stable power supply. A heating wire is threaded through the inner side of the galvanized conduit 3. The control box 301, as the core control unit, provides power to the heating wire, precisely regulates its working state, and ensures safe operation. The heating wire, as the actuator, converts electrical energy into heat energy under the command of the control box 301. The heat generated can prevent large-scale leakage of cold air when the cold storage insulation door is normally open.

[0033] It is worth mentioning that the heating wire can be made of carbon fiber. Compared with traditional metal heating wire, carbon fiber has a higher electrothermal conversion efficiency (≥98%), better resistance stability at low temperatures, and energy consumption is reduced by 20%-30%.

[0034] Furthermore, such as Figure 4 and Figure 5 As shown, two grooves 9 are formed on the inner bottom of the heating threshold 1. Insert rods 10 are slidably connected to the inner sides of both grooves 9. One end of each insert rod 10 penetrates the outer wall of the heating threshold 1. Two locking blocks 11 are fixedly connected to the top of each insert rod 10. The locking blocks 11 can precisely hold the galvanized wire pipe 3, pressing it between the locking blocks 11 and the supporting block 4 below. The galvanized wire pipe 3 is located between the locking blocks 11 and the insert rod 10. Several equidistant protrusions 12 are formed on the surface of each insert rod 10 on opposite sides. The protrusions 12 mesh with gears 5. Gears 5 are rotatably connected to the inner bottom surface of the heating threshold 1 between the two insert rods 10. A fixing block 6 is fixedly connected to the top of the gear 5. 01. A crossbar 6 is fixedly connected to the top of the fixing block 601. After the galvanized wire pipe 3 and heating wire are installed, the crossbar 6 rotates, driving the gear 5 to rotate. The insert rods 10 on both sides of the gear 5 slide to both sides along their respective sliding grooves 9 under the meshing action of the convex teeth 12. The insert rods 10 extend out of the heating threshold 1 and are inserted into the holes reserved in the inner wall of the foundation 102 to fix the heating threshold 1, so that it cannot move freely up and down and remains fixed. At the same time, during the sliding process of the insert rods 10, the locking blocks 11 on its surface will also limit the galvanized wire pipe 3, improving the stability of the galvanized wire pipe 3. It can also be used normally and remain stable when encountering vibrations caused by frequent goods entering and exiting.

[0035] It is worth noting that, such as Figure 4 and Figure 5 As shown, the inner walls of the front and rear sides of the heating threshold 1, corresponding to the horizontal height of the crossbar 6, are provided with arc-shaped grooves 7. The height of the arc-shaped grooves 7 is the same as the thickness of the crossbar 6. Two bolt holes 8 are provided on the top surface of the heating threshold 1 above the arc-shaped grooves 7. These two bolt holes 8 are connected to the arc-shaped grooves 7. After the galvanized wire pipe 3 is threaded with the heating wire and connected to the control box 301, the galvanized wire pipe 3 will be placed on the support block 4. At this time, the crossbar 6 is rotated so that the two ends of the crossbar 6 enter the center of the arc-shaped grooves 7 on the front and rear sides respectively and form a limit. When the cover plate 2 is closed and the fixing bolts 201 are screwed in, the two fixing bolts 201 at the arc-shaped grooves 7 will just restrict the crossbar 6 in the center, thereby ensuring the stability of the crossbar 6. The crossbar 6 also controls the rotation of the gear 5, thereby keeping the insertion rod 10 fixed and stably inserted into the hole reserved in the foundation 102, thus fixing the entire heating threshold 1 between the foundation 102 and the threshold body 101.

[0036] It is worth noting that the left and right outer walls of the heating threshold 1 are provided with positioning strips 104. The positioning strips 104 are inserted into the inner side of the positioning grooves 103 opened on the side wall of the threshold body 101. The heating threshold 1 is vertically slidably connected to the threshold bodies 101 on the left and right sides. The size of the positioning grooves 103 is slightly larger than that of the positioning strips 104, thereby providing a certain space for the entire heating threshold 1 to expand under heat, avoiding the mutual collision and bulging caused by a tight fit. The threshold body 101 and the front and rear sides of the threshold body 101 are the foundation 102. The heating threshold 1 is actually a part cut off from the threshold body 101. When it is spliced ​​together with the threshold body 101, it is exactly the threshold of the entire cold storage door. In order to maintain the seal, a rubber sealing strip can be set on the contact surface between the threshold body 101 and the heating threshold 1. It has the effect of isolating cold air and also has elasticity to adapt to the thermal expansion of the heating threshold 1. The inner wall of the foundation 102 will have holes and grooves in advance at the positions corresponding to the insertion rods 10 on the front and rear sides of the heating threshold 1, so as to facilitate the insertion of the insertion rods 10, thereby ensuring the stability of the heating threshold 1.

[0037] It is worth mentioning that a heat insulation layer 13 is provided at the bottom inner side of the heating threshold 1. This heat insulation layer 13 can be made of nano-aerogel, which has super heat insulation performance, extremely low thermal conductivity, and heat preservation performance three to five times that of traditional heat preservation materials. It can effectively block extreme temperatures and also has excellent properties such as waterproofing and anti-aging. When used here, it can effectively prevent the heat of the heating wire from being conducted to the ground, so that the heat is transferred upward and outward, reducing the leakage of cold air.

[0038] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0039] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
