[0007] A support column is arranged on the support cover body, a power generation unit is connected to the support column, a driving end of the power generation unit is connected to a rotating shaft, and the rotating shaft is connected to blades.

[0008] A further improvement of the present invention is:

[0009] The support cover body comprises an upper cover body, the upper cover body is connected to the upper end of the chimney to be fixed, the lower end of the upper cover body is connected to the support rod, and the lower end of the support rod is connected to the lower cover body.

[0013] The outer support rods are distributed circumferentially along the outer side wall of the chimney to be fixed.

[0014] Elastic members are arranged on the side walls of the inner support rod and the outer support rod close to the chimney to be fixed.

[0015] The elastic member is an elastic steel plate.

[0016] The support column is fixedly connected to the support cover body.

[0017] The support column is rotatably connected to the support cover body.

[0018] The power generation unit is a generator.

[0019] A bearing sleeve is arranged at the connection between the power generation unit and the rotating shaft.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention discloses a device for generating electricity on the top of a chimney. The device is directly installed on the top of the chimney, and there is no need to occupy additional land area on the ground or nearby areas, which saves land resources and maximizes the use of space. The power generation equipment disclosed by the device does not require large-scale ground transformation to install, which improves the flexibility and feasibility of project implementation. In addition, the cost of building an independent support frame is saved, there is no need for additional support frames, the installation process is simpler and faster, and the construction period and manpower investment are reduced. At the same time, the safety risks during the installation process are also reduced, because there is no need to build a complex support structure at high altitude. By directly fixing the power generation unit on the support cover at the top of the chimney, the high strength and stability of the chimney itself are used as the support basis, which ensures the safety and reliability of the power generation equipment under severe weather conditions.

[0022] Furthermore, in the present invention, the support cover includes an upper cover, the upper cover is connected to the upper end of the chimney to be fixed, the lower end of the upper cover is connected to the support rod, the lower end of the support rod is connected to the lower cover, the upper cover is directly connected to the upper end of the chimney, providing a first layer of stable support; and the lower cover is connected to the upper cover through the support rod, forming a second layer of support structure. This double protection design significantly enhances the stability of the entire power generation equipment at the top of the chimney, ensuring that it can operate stably under various climatic conditions. The design of the support rod not only plays a connecting role, but also effectively disperses the impact of external factors such as wind and vibration on the power generation equipment, reduces structural stress concentration, and extends the service life of the equipment.

[0023] Furthermore, in the present invention, a groove corresponding to the upper end of the chimney to be fixed is formed at the lower end of the upper cover, and the groove is sleeved on the upper end of the chimney. The groove design enables the upper cover to be accurately sleeved on the upper end of the chimney, thereby achieving seamless connection between the device and the chimney. This design not only improves the accuracy of installation, but also ensures the stability of the device on the top of the chimney, reduces the risk of shaking or falling off due to improper installation, and the groove design simplifies the connection process between the device and the chimney, without the need for complex fixing devices or additional installation steps.

[0024] Furthermore, in the present invention, the support rods include inner support rods and outer support rods; the inner support rods are distributed circumferentially along the inner wall of the chimney to be fixed, and the outer support rods are distributed circumferentially along the outer wall of the chimney to be fixed. The inner and outer double support structures significantly enhance the structural strength of the entire power generation equipment at the top of the chimney. The inner support rods are close to the inner wall of the chimney, providing inward support force; while the outer support rods are distributed along the outer wall, providing outward support force. This two-way support effect makes the equipment more stable and able to withstand stronger wind forces and other external forces. The circumferentially distributed inner and outer support rods form a uniform support network, which makes the center of gravity of the equipment at the top of the chimney more stable. No matter how the wind direction changes, the equipment can maintain a relatively balanced state, reducing the shaking or tilting caused by uneven wind force.

[0025] Furthermore, in the present invention, elastic members are arranged on the side walls of the inner support rods and the outer support rods close to the chimney to be fixed, and the elastic members can allow the inner support rods and the outer support rods to make slight dynamic adjustments when subjected to external forces. This adaptability helps to ensure that the support structure always maintains close contact with the chimney surface, reducing stress concentration caused by gap changes. In strong wind conditions, the elastic members can absorb part of the wind impact, reducing the impact of wind pressure on the support structure and the entire power generation equipment, thereby improving the wind resistance and stability of the equipment.

[0026] Furthermore, in the present invention, the support column is fixedly connected to the support cover, and the fixed connection between the support column and the support cover provides a stable structural support, so that the entire power generation equipment can be firmly installed and fixed on the top of the chimney. This rigid connection helps to resist adverse factors such as external wind force and vibration, and ensures long-term stable operation of the equipment.

[0027] Furthermore, in the present invention, the support column is rotatably connected to the support cover, and the rotatable connection allows the support cover to automatically adjust according to changes in wind direction, so that the power generation equipment always faces the best wind energy source, thereby improving power generation efficiency.

[0028] Furthermore, in the present invention, a bearing sleeve is provided at the connection between the power generation unit and the rotating shaft. The bearing sleeve serves as an intermediary between the power generation unit and the rotating shaft, and can effectively reduce direct contact between the two, thereby reducing wear caused by friction.

[0042] Furthermore, in this embodiment, during implementation, first, the support cover is accurately fixed on the top of the chimney according to the design requirements, and then the support column 5 is installed on the support cover to ensure its verticality and stability. The blade 2 is a key component for capturing wind energy. When natural wind blows over the blade, the blade begins to rotate under the action of wind force, and the rotation of the blade 2 is transmitted to the driving end of the power generation unit through the shaft 3. The design of the shaft 3 must take into account sufficient rigidity and wear resistance to ensure the efficiency and stability of power transmission. The shaft 3 may also be equipped with bearings or other friction reduction devices to reduce friction and energy loss during rotation. After the driving end of the power generation unit receives the power from the shaft 3, it drives the generator or other power generation mechanism inside it to start working. The generator uses the principle of electromagnetic induction to convert mechanical energy into electrical energy. The electrical energy generated during the conversion process can be transmitted to the power grid or energy storage device through cables or other transmission devices.

[0043] The device disclosed in this embodiment is directly installed on the top of the chimney, without occupying additional land area on the ground or nearby areas, saving land resources and maximizing the use of space.
