Description

Technical Field

[0001] This utility model relates to the technical field of off-peak electricity heating, and in particular to a thermal storage type off-peak electricity heating conversion device. Background Technology

[0002] The heat conversion equipment is the core hub of the thermal system, responsible for efficiently and controllably transferring the energy of the primary heat source (such as boiler, industrial waste heat, geothermal energy, etc.) to the secondary heat supply circuit, while realizing medium conversion, parameter adjustment and safety assurance.

[0003] Off-peak electricity heating technology can be an important part of the clean energy transition, especially suitable for the peak-shaving needs of grids with a high proportion of renewable energy. In practical applications, the technology selection should be combined with local electricity price policies, climate conditions and building characteristics.

[0004] The existing technical solutions mentioned above have the following drawbacks: existing off-peak electric heating equipment basically converts solar energy directly into electrical energy or solar energy into heat energy. However, separating the two processes results in mediocre heating effects and reduces the overall utilization of solar energy, thus reducing the overall heating effect. Utility Model Content

[0005] The purpose of this invention is to provide a thermal storage-type off-peak electricity heating conversion device that fully collects and utilizes solar energy in multiple stages.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A heat storage type off-peak electricity heating conversion device includes a heat storage tank for storing the heating medium. The upper end of the heat storage tank is detachably connected to a tank cover. A solar tube is fixedly connected to the upper end of the tank cover. One end of the solar tube extends through the upper end of the tank cover into the interior of the heat storage tank. The solar tube on the outside of the heat storage tank is in the shape of a serpentine tube. An electric heating device is fixedly connected to the left side of the heat storage tank. A heating tube is fixedly connected to the heating end of the electric heating device. The heating tube extends through the outside of the heat storage tank into the interior of the heat storage tank. The heating tube inside the heat storage tank is in the shape of a serpentine tube.

[0008] By adopting the above technical solution, the serpentine solar tube can fully absorb solar energy, while the electric heating device can fully heat the heating medium inside the heating storage tank when the overall temperature is insufficient, ensuring a good overall heating effect.

[0009] Furthermore, a first circulation pump is fixedly connected to the outside of the solar tube on the outside of the heating storage tank. A first solar power supply mechanism for supplying power to the first circulation pump is fixedly connected to the upper end of the first circulation pump. The first solar power supply mechanism includes a solar battery. A solar photovoltaic panel for absorbing solar energy and converting solar energy into electrical energy for the solar battery is fixedly connected to the upper end of the solar battery.

[0010] By adopting the above technical solution, the first circulation pump can circulate the heating medium inside the heating storage tank, which not only ensures that the heating medium inside the heating storage tank is fully irradiated and heated, but also ensures that the heating medium is fully heated, thereby improving the overall heating effect.

[0011] Furthermore, a second solar power supply mechanism for supplying power to the electric heating device is fixedly connected to the upper end of the electric heating device. The second solar power supply mechanism has the same specifications as the first solar power supply mechanism.

[0012] By adopting the above technical solution, the second solar power supply mechanism and the first solar power supply mechanism can absorb solar energy and convert it into electrical energy, ensuring that the heating medium is fully heated.

[0013] Furthermore, a circulation pipe for connecting to a heating pipeline is fixedly connected to the lower end of the heating storage tank, and a second circulation pump is fixedly connected to the outside of the circulation pipe. The circulation pipe is symmetrically distributed about the horizontal center line of the heating storage tank.

[0014] By adopting the above technical solution, the circulation pipe can be connected to the heating pipeline to achieve overall heating, realize the effect of off-peak electricity heating, reduce overall resource consumption, and increase overall practicality.

[0015] Furthermore, the upper end of the heating storage box is provided with a sealing groove, and the lower end of the box cover is fixedly connected with a sealing block that matches the sealing groove. A spring latch is movably connected inside the sealing block, and the side wall of the heating storage box is provided with a positioning hole that communicates with the inside of the sealing groove.

[0016] By adopting the above technical solution, no leakage will occur during the insertion of the sealing block and the sealing groove, thereby ensuring the normal operation of the whole and facilitating the overall heat preservation.

[0017] Furthermore, the sealing block has a movable groove inside for the spring latch to move, and a mounting spring is movably connected inside the movable groove. The side of the mounting spring away from the movable groove is fixedly connected to the spring latch, and the spring latch is adapted to the positioning hole.

[0018] The above technical solution allows the spring to engage with the positioning hole, making it easy to open and close the lid. This facilitates cleaning and maintenance, and increases overall flexibility.

[0019] In summary, the beneficial technical effects of this utility model are as follows:

[0020] 1. The solar tubes, which adopt a serpentine tube structure, can fully absorb solar energy. At the same time, the electric heating device can fully heat the heating medium inside the heating storage tank when the overall temperature is insufficient, ensuring a good overall heating effect and achieving the effect of dual solar energy conversion to increase heating.

[0021] 2. The first circulation pump is used to circulate the heating medium inside the heating storage tank. This not only ensures that the heating medium inside the heating storage tank is fully irradiated and heated, but also ensures that the heating medium is fully heated, thereby improving the overall heating effect and achieving the effect of fully heating and increasing the heating effect.

[0022] 3. The installation spring drives the spring latch to engage with the positioning hole, making it easy to open and close the lid. This facilitates cleaning and maintenance, increases overall flexibility, and achieves the effect of easy cleaning and maintenance. Attached Figure Description
