[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0013] A temperature regulating fixture for facilitating the construction of composite phase change asphalt pavement includes: a bearing plate assembly 1 and a box assembly 2, wherein the lower end of the bearing plate assembly 1 is fixed with the box assembly 2.

[0014] The support plate assembly 1 includes: a support plate 1-1, transverse water channels 1-2, connecting water channels 1-3, a mesh plate 1-4, connecting holes 1-5, water pipes 1-6, connecting pipes 1-7, drain pipes 1-8, and a one-way valve 1-9. The top surface of the support plate 1-1 is provided with multiple transverse water channels 1-2, each transverse water channel 1-2 having a conical bottom surface. The top surface of the support plate 1-1 is symmetrically provided with two connecting water channels 1-3, each connecting water channel 1-3 being connected to both ends of the multiple transverse water channels 1-2. Each of the 1-3 bottom surfaces is provided with a connecting hole 1-5, which penetrates the bottom surface of the support plate 1-1. A mesh plate 1-4 can be detachably fixed on each of the multiple horizontal water tanks 1-2 and the two connecting water tanks 1-3. Multiple water pipes 1-6 are provided inside the support plate 1-1, and the multiple water pipes 1-6 are connected to each other through a connecting pipe 1-7. A drain pipe 1-8 is provided at the lower end of the rightmost water pipe 1-6, and the drain pipe 1-8 extends out of the bottom surface of the support plate 1-1. A one-way valve 1-9 is fixedly connected to the lower end of the drain pipe 1-8.

[0015] The housing assembly 2 includes: housing 2-1, submersible pump 2-2 and heating rod 2-3. The housing 2-1 is fixed to the lower end of the support plate 1-1. The submersible pump 2-2 and heating rod 2-3 are fixed inside the housing 2-1. The connecting hole 1-5 is fixedly connected to the top surface of the housing 2-1. The drain pipe 1-8 is fixedly inserted into the housing 2-1. The water outlet of the submersible pump 2-2 is fixedly connected to the water pipe 1-6 located on the leftmost side.

[0016] The working principle of this utility model is as follows:

[0017] This utility model is laid continuously along the planned road or bridge, with multiple units side by side. During use, composite phase change asphalt and aggregate can be laid on the bearing plate 1-1. The mesh plate 1-4 can block the composite phase change asphalt and aggregate from falling into the transverse water channel 1-2 and connecting water channel 1-3, preventing blockage. The submersible pump 2-2 and heating rod 2-3 can be connected to the power supply of municipal streetlights on both sides of the road and controlled individually. During rainy weather, water permeates through the composite phase change asphalt and aggregate into the transverse water channel 1-2, flows along the tapered bottom of the transverse water channel 1-2 to both sides into the connecting water channel 1-3, and then flows into the collection box 2-1 through the connecting hole 1-5. In summer, when the road surface temperature is high, the submersible pump 2-2 is powered on, and the collection box 2-1... Water is pumped out of tank 2-1 and sent to water pipe 1-6, then flows into other water pipes 1-6 through connecting pipe 1-7. When water pipe 1-6 is full, the water flows back into tank 2-1 through drain pipe 1-8 at the far right and check valve 1-9 to complete the circulation. Check valve 1-9 is designed to prevent backflow of water in tank 2-1. The heat from the road surface is transferred to the bearing plate 1-1. The circulating water in water pipe 1-6 can cool the bearing plate 1-1, thereby cooling the road surface and preventing uneven ripples. In winter, heating rod 2-3 is powered on to heat the water inside tank 2-1, preventing the water in tank 2-1 from freezing. At the same time, the water is circulated through submersible pump 2-2 to heat the road surface and reduce the freezing phenomenon.

[0018] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
