Description

Technical Field

[0001] This application relates to the technical field of anti-freezing and heat preservation devices for mass concrete, specifically an anti-freezing and heat preservation device for mass concrete. Background Technique

[0002] Mass concrete refers to concrete structures with a minimum geometric dimension of the entity not less than one meter. In some construction sites, the construction of mass concrete is also required. For example, when making concrete blocks, the surface coefficient of mass concrete is relatively small, the heat release of cement hydration is relatively concentrated, and the internal temperature rises relatively fast. When the temperature difference between the inside and outside of the mass concrete is relatively large, temperature cracks will occur in the mass concrete, affecting the structural safety and normal use. Therefore, an anti-freezing and heat preservation device for mass concrete is needed to keep the concrete blocks warm.

[0003] For example, Chinese Patent (Publication No.: CN217711836U) discloses an anti-freezing and heat preservation device for mass concrete, including a heat preservation board and a heating component arranged on the outer side of the concrete block. The heat preservation board is fixed on the side wall of the concrete block. An installation groove is opened on one side of the heat preservation board. The heating component includes a solar panel, a storage battery electrically connected to the solar panel, and a heating plate electrically connected to the storage battery. The heating plate is installed in the installation groove. This application has the effect of being able to keep the concrete block warm, thereby improving the problem that the concrete block is prone to cracking due to the large temperature difference between day and night in high-altitude and cold regions.

[0004] However, there are still some deficiencies in the above-mentioned retrieved patent. It sets multiple heating plates inside the heat preservation board for heating and heat preservation. When one of the heating plates is damaged and not discovered in time, it will cause the unilateral heat loss of the concrete block and then affect the block due to uneven temperature. When repairing the heating plate, it is also necessary to disassemble the waterproof board and the heat preservation board and then disassemble the heating plate, and the steps are very cumbersome and inconvenient. Therefore, this application proposes an anti-freezing and heat preservation device for mass concrete to solve the above problems. Utility Model Content

[0006] To achieve the above object, this application provides the following technical solution: An anti-freezing and heat preservation device for mass concrete, including a bottom plate, an annular plate installed on the top surface of the bottom plate, a heating mechanism arranged on the bottom plate, and a cover plate installed on the top surface of the annular plate;

A rectangular hole is formed in the top surface of the heating chamber.

[0008] With the above technical solution, during use, a heat preservation box is formed by the arranged bottom plate and the annular plate to place concrete blocks for heat preservation.

[0010] With the above technical solution, heat is transported to the heat conduction component through a liquid heat conduction medium and a water pump. The heat conduction component makes the heat conduction more uniform through the vertical pipes and connecting pipes evenly arranged around the blocks, and will not cause unilateral heat loss of the concrete blocks to affect heat preservation. It has better practicability and is more convenient for popularization and use.

[0011] Furthermore, the fixing mechanism includes a rotating rod rotatably connected to the top surface of the sealing plate, a main bevel gear installed at the bottom end of the rotating rod, a support plate installed on the bottom surface of the sealing plate, a screw rod rotatably connected to the left side of the support plate and penetrating through the support plate, a driven bevel gear installed on the outer peripheral wall of the screw rod and meshing with the main bevel gear, a limit block threadedly connected to the outer peripheral wall of the screw rod, and a guide block installed on the top surface of the limit block. A guide groove for the sliding connection of the guide block is formed in the bottom surface of the sealing plate.

[0012] With the above technical solution, when the sealing plate needs to be opened, rotating the rotating rod can drive the limit block to move, thereby facilitating the pushing and disassembly of the sealing plate.

[0013] Furthermore, both the bottom plate and the annular plate are heat preservation plates, and the cover plate is fixed to the annular plate by bolts.

[0014] With the above technical solution, it is convenient to improve the heat preservation performance of the device.

[0015] Furthermore, the heating chamber is filled with a heat conduction liquid, and the water inlet end of the water pump is communicated with the heating chamber.

[0016] With the above technical solution, it is convenient to make the heat conduction liquid flow through the water pump, thereby ensuring a constant temperature.

The left end of the horizontal pipe penetrates through the first annular pipe and is communicated with it. One end of the connecting pipe is communicated with the first annular pipe, and the other end is communicated with the horizontal pipe.

[0033] During use, a heat preservation box is formed by the provided bottom plate 1 and the annular plate 2 to place concrete blocks for heat preservation. After the concrete blocks are placed, the heating chamber 301 provided by the heating mechanism 3 can continuously generate heat, and the heat is transported to the heat conduction component through a liquid heat conduction medium and the water pump 303. The heat conduction components are evenly arranged around the blocks, and the heat conduction is more uniform, which will not cause unilateral heat loss of the concrete blocks and affect heat preservation. The practicability is better and it is more convenient to promote and use.

[0034] In this embodiment, both the bottom plate 1 and the annular plate 2 are heat preservation plates. The cover plate 4 is fixed to the annular plate 2 by bolts. The heating chamber 301 is filled with heat conduction liquid, and the water inlet end of the water pump 303 is communicated with the heating chamber 301.

[0035] Please refer to Figures 1-3 , in this embodiment, the heat conduction assembly includes a first annular pipe 306 installed inside the bottom plate 1, a horizontal pipe 307 installed inside the bottom plate 1, a second annular pipe 308 installed inside the annular plate 2, a connecting pipe 309 installed inside the bottom plate 1, a vertical pipe 310 installed inside the annular plate 2, a water supply pipe 311 installed at the water outlet end of the water pump 303, and a water return pipe 312 installed on the left side of the annular plate 2. The water pump 303 is arranged on the top of the cover plate 4 for easy maintenance. At the same time, the heating pipe 302 is arranged inside the heating chamber 301.

[0036] During use, the fixing mechanism 5 is provided to facilitate the disassembly of the sealing plate 304, and then the heating pipe 302 can be maintained and repaired. The heating pipes 302 are centrally arranged in the heating chamber 301. Even if a single one is damaged, it will not cause uneven temperature of the concrete blocks, and the practicability is better.

[0037] , in this embodiment, the first annular pipe 306 and the second annular pipe 308 are vertically opposite. The left end of the horizontal pipe 307 penetrates through the first annular pipe 306 and is communicated with it. One end of the connecting pipe 309 is communicated with the first annular pipe 306, and the other end is communicated with the horizontal pipe 307.

[0038] Please refer to Figures 1-3 , the top end of the vertical pipe 310 is communicated with the second annular pipe 308, and the bottom end is communicated with the first annular pipe 306.

Heat insulation cotton sleeves are fixed on the outer peripheral walls of the heating chamber 301, the water supply pipe 311, and the water return pipe 312.

[0039] During use, put the concrete blocks and fix the cover plate 4 with bolts. Start the heating pipe 302 to heat the heat-conducting liquid inside the heating chamber 301, and then start the water pump 303. The water pump 303 transports the heat-conducting liquid to the horizontal pipe 307 through the water supply pipe 311, and further transports it to the first annular pipe 306 through the connecting pipes 309 on both sides of the horizontal pipe 307. When the heat-conducting liquid enters the first annular pipe 306, it will enter multiple vertical pipes 310 for diversion. The heat-conducting liquid is transported upward along the vertical pipes 310 and converges at the second annular pipe 308, and is transported back to the heating chamber 301 through the water return pipe 312. The heat-conducting liquid circulates uniformly inside the annular plate 2 and the bottom plate 1, achieving the effect of heating the concrete blocks.

[0040] Please refer to Figures 1-3, in this embodiment, the fixing mechanism 5 includes a rotating rod 501 rotatably connected to the top surface of the sealing plate 304, a main bevel gear 502 mounted at the bottom end of the rotating rod 501, a support plate 503 mounted on the bottom surface of the sealing plate 304, a screw rod 504 rotatably connected to the left side of the support plate 503 and passing through the support plate 503, a driven bevel gear 505 mounted on the outer peripheral wall of the screw rod 504 and meshing with the main bevel gear 502, a limit block 506 threadedly connected to the outer peripheral wall of the screw rod 504, and a guide block 507 mounted on the top surface of the limit block 506. A guide groove 508 for the sliding connection of the guide block 507 is formed on the bottom surface of the sealing plate 304.

[0041] When it is necessary to open the sealing plate 304, rotate the rotating rod 501. The rotating rod 501 drives the main bevel gear 502 to rotate. The main bevel gear 502 drives the two driven bevel gears 505 to rotate synchronously and in opposite directions. The two driven bevel gears 505 drive the two screw rods 504 with the same thread direction to rotate synchronously and in opposite directions. Further, the screw rod 504 drives the limit block 506 to cooperate with the guide block 507 and slide along the guide groove 508 towards the main bevel gear 502. When the limit block 506 disengages from the inner top wall of the heating chamber 301, the sealing plate 304 can be removed from the rectangular hole 305. When it is necessary to fix it, rotate the rotating rod 501 in the reverse direction to fix the sealing plate 304.

[0042] , in this embodiment, a handle is fixed to the top end of the rotating rod 501. A threaded groove for the threaded connection of the screw rod 504 is formed at one end of the limit block 506 facing the main bevel gear 502. The top surface of the limit block 506 and the side away from the main bevel gear 502 is an inclined surface.

[0043] The working principle of the above embodiment is as follows:

[0044] (1). During use, put the concrete block and fix the cover plate 4 with bolts. Start the heating tube 302 to heat the heat-conducting liquid inside the heating chamber 301, and then start the water pump 303. The water pump 303 transports the heat-conducting liquid to the horizontal tube 307 through the water supply pipe 311, and further transports it to the first annular tube 306 through the connecting pipes 309 on both sides of the horizontal tube 307. When the heat-conducting liquid enters the first annular tube 306, it will enter a plurality of vertical tubes 310 for diversion. The heat-conducting liquid is transported upward along the vertical tubes 310 and converges at the second annular tube 308, and is transported back to the heating chamber 301 through the return pipe 312. The heat-conducting liquid circulates uniformly inside the annular plate 2 and the bottom plate 1, achieving the effect of heating the concrete block.

[0045] (2) When it is necessary to open the sealing plate 304, rotate the rotating rod 501. The rotating rod 501 drives the main bevel gear 502 to rotate. The main bevel gear 502 drives the two driven bevel gears 505 to rotate synchronously in opposite directions. The two driven bevel gears 505 drive the two screws 504 with the same thread direction to rotate synchronously in opposite directions. Further, the screw 504 drives the limiting block 506 to cooperate with the guiding block 507 and slide along the guiding groove 508 towards the side of the main bevel gear 502. When the limiting block 506 disengages from the inner top wall of the heating chamber 301, the sealing plate 304 can be removed through the rectangular hole 305. When it is necessary to fix it, reverse-rotate the rotating rod 501 to fix the sealing plate 304.
