Description

Technical Field

[0001] The present invention relates to the field of energy towers, and more specifically, to a hybrid energy tower based on solar energy and air energy. Background Art

[0002] An energy tower is a tower-type heat exchange device that uses a heat transfer medium to exchange heat with air therein and provides continuous cold and heat sources for a heat pump unit. The energy tower mainly includes parts such as a tower body, a fan, a heat exchanger, a sprayer, and an antifreeze water replenishing system. It is mainly classified into an open energy tower and a closed energy tower. The main difference between the two lies in the heat exchanger. The heat exchanger of the open energy tower uses packing, and the heat exchanger of the closed energy tower is a copper tube and fins.

[0003] Traditional energy towers mainly rely on the heat exchange between a circulating agent and air to transport cold and heat sources. In winter, due to the low ambient temperature and less heat energy in the air, the heat source collection efficiency of the energy tower is not high during winter heating, affecting the operation efficiency of the energy tower. Summary of the Invention

When the fan rotates in the reverse direction, the fan drives the shielding cylinder to rotate through a one-way acceleration transmission assembly, so that the light-transmitting holes of the shielding cylinder are misaligned with the Fresnel lenses.

[0008] As a further solution of the present invention: an opening communicating with the housing is provided at the upper end of the shielding cylinder. The one-way deceleration transmission assembly includes a fixed disk fixed at the opening at the upper end of the shielding cylinder. A rotating disk is nested inside the fixed disk. A pawl hinged on the side wall of the rotating disk is clamped with the inner wall of the fixed disk. The rotating disk is fixedly connected with a prism cylinder extending to the outside of the fixed disk and rotatably connected thereto. A prism shaft passes through the prism cylinder. The upper end of the prism shaft is connected to an inner rotating shaft through a first transmission gear set. The inner rotating shaft is connected to an upper connecting shaft through a second transmission gear set. The upper connecting shaft is fixedly connected to the front end of the output shaft of the fan.

[0009] As a further solution of the present invention: the liquid inlet pipe includes a central pipe passing through the central position of the packing cylinder. The upper end of the central pipe is communicated with the spray pipe through a rotary joint. The upper end of the spray pipe is fixedly connected with a plug-in cylinder. The prism shaft is inserted into the plug-in cylinder.

[0010] As a further solution of the present invention: the fixed disk is fixedly connected with the shielding cylinder through a connecting plate integrally formed therewith. The fixed disk is provided with a cylindrical cavity for accommodating the rotating disk. The inner wall of the cylindrical cavity is provided with a pawl groove cooperating with the pawl.

[0011] As a further solution of the present invention: the distance between adjacent Fresnel lenses is greater than the diameter of the Fresnel lens.

[0012] As a further solution of the present invention: the inner rotating shaft is rotatably connected with a protective cylinder sleeved outside the first transmission gear set and the second transmission gear set. The protective cylinder is fixedly connected with the inner wall of the housing through a connecting rod integrally formed therewith.

[0013] As a further solution of the present invention: the housing is of a cylindrical structure. A water collecting cavity is provided at the position of the housing below the air inlet net. The water collecting cavity is a conical cavity with the tip facing downwards. The water collecting cavity is communicated with the drain pipe.

[0014] As a further solution of the present invention: the packing cylinder is of a cylindrical structure. The lower end of the packing cylinder abuts against a bearing liquid leakage disk fixedly connected with the inner wall of the housing. The bearing liquid leakage disk is provided with uniformly distributed liquid leakage holes.

[0015] As a further solution of the present invention: the spray pipe is fixedly connected with multiple groups of nozzles evenly distributed. The plug-in cylinder is provided with a prism groove for inserting the prism shaft.

[0016] As a further solution of the present invention: the heat exchange cavity is a ribbed cavity penetrating the packing cylinder. The central pipe is a vertical pipe made of a heat-conducting material.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) The present invention realizes the concentration of sunlight through a filler cylinder with a vertical heat exchange cavity and made of transparent material, and a Fresnel lens uniformly distributed on the tower body shell, and enables the sunlight to irradiate and transfer heat to the filler cylinder, realizing the mixed heat exchange between the circulating liquid and solar energy and air energy, improving the heat source collection efficiency of the energy tower in winter, and improving the operation efficiency of the energy tower.

[0019] (2) The present invention is provided with a shielding cylinder arranged between the Fresnel lens and the packing tower, and a light-transmitting hole corresponding to the Fresnel lens is opened on the shielding cylinder. Since the shielding cylinder is connected and driven with the fan through a one-way decelerating transmission component, when heat exchange with solar energy is not required, the fan drives the shielding cylinder to rotate through the one-way decelerating transmission component, so that the light-transmitting hole and the Fresnel lens are misaligned, realizing the control of the light incident amount or completely shielding the light, and the operation is convenient.

[0020] (3) The present invention is provided with a one-way decelerating transmission component including a prismatic cylinder, a prismatic shaft, a pawl, a first transmission gear set and a second transmission gear, realizing the one-way rotation of the fixed disk, not affecting the normal operation of the fan, and facilitating the adjustment of the shielding cylinder at the same time.

[0021] (4) The present invention is provided with a spray pipe linked with the fan and a heat exchange cavity in a prismatic shape, so that the circulating liquid flows uniformly through the heat exchange cavity, and the sunlight is fully refracted in the filler cylinder, improving the heat exchange efficiency.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0036] Please refer to Figures 1-10, in an embodiment of the present invention, a hybrid energy tower based on solar energy and air energy includes a housing 1. Inside the housing 1, a packing cylinder 2 is installed. Above the packing cylinder 2, a spray pipe 3 is installed. The spray pipe 3 is connected to a liquid inlet pipe 4. An air inlet net 5 is installed on the side wall of the housing 1 below the packing cylinder 2. A fan 7 is installed at the upper opening of the housing 1. The lower end of the housing 1 is connected to a liquid discharge pipe 6. The packing cylinder 2 is provided with heat exchange cavities 201 that are evenly distributed and vertically penetrate the packing cylinder 2. The packing cylinder 2 is made of a transparent material. On the side wall of the housing 1 outside the packing cylinder 2, evenly distributed Fresnel lenses 8 are installed. Between the packing cylinder 2 and the side wall of the housing 1, there is a shielding cylinder 9 rotatably connected to the inner wall of the housing 1. The shielding cylinder 9 is provided with light-transmitting holes 901 corresponding to the Fresnel lenses 8 one by one. The shielding cylinder 9 is connected and driven by a one-way deceleration transmission assembly to the output shaft of the fan 7. When the fan 7 rotates in the reverse direction, the fan 7 drives the shielding cylinder 9 to rotate through a one-way acceleration transmission assembly, so that the light-transmitting holes 901 of the shielding cylinder 9 are misaligned with the Fresnel lenses 8.

[0037] Specifically, when the energy tower is working, the fan 7 and an external heat pump unit are started. When heating in winter, the external heat pump unit injects the circulating liquid into the spray pipe 3 through the liquid inlet pipe 4 and sprays it out. The sprayed circulating liquid is sprayed on the packing cylinder 2 and flows downward through the heat exchange cavity 201. The suction generated by the fan 7 causes the external air to be injected into the housing 1 through the air inlet net 5 and enter the heat exchange cavity 201. At the same time, the Fresnel lenses 8 on the outer wall of the housing 1 irradiate the sunlight through the light-transmitting holes 901 on the transparent packing cylinder 2, so that the circulating liquid flowing downward along the heat exchange cavity 201 exchanges heat with the heat energy of the sunlight and the heat energy of the air, enabling the circulating liquid to obtain more heat. The heat-exchanged circulating liquid flows back to the external heat pump unit through the liquid discharge pipe 6, improving the operating efficiency of the energy tower.

[0038] When cooling in summer, the fan 7 is started in the reverse direction. The fan 7 drives the shielding cylinder 9 to rotate through a one-way acceleration transmission gear set, so that the light-transmitting holes 901 on the shielding cylinder 9 are misaligned with the Fresnel lenses 8, preventing external light from entering the housing 1 to irradiate and transfer heat to the packing cylinder 2, and ensuring the heat dissipation effect of the sprayed circulating liquid.

[0039] Please refer to Figure 5, in this embodiment, an opening communicating with the housing 1 is provided at the upper end of the shielding cylinder 9. The one-way speed reduction transmission assembly includes a fixed disk 10 fixed at the opening at the upper end of the shielding cylinder 9. A rotating disk 11 is nested inside the fixed disk 10. A pawl 12 hinged on the side wall of the rotating disk 11 is clamped with the inner wall of the fixed disk 10. The rotating disk 11 is fixedly connected with a prism cylinder 13 extending to the outside of the fixed disk 10 and rotatably connected thereto. A prism shaft 14 passes through the prism cylinder 13. The upper end of the prism shaft 14 is connected to an inner rotating shaft 16 through a first transmission gear set 15. The inner rotating shaft 16 is connected to an upper connecting shaft 18 through a second transmission gear set 17. The upper connecting shaft 18 is fixedly connected to the front end of the output shaft of the fan 7.

[0040] Please refer to Figures 5-7 , in this embodiment, the fixed disk 10 is fixedly connected to the shielding cylinder 9 through a connecting plate integrally formed therewith. The fixed disk 10 is provided with a cylindrical cavity for accommodating the rotating disk 11. The inner wall of the cylindrical cavity is provided with a pawl groove cooperating with the pawl 12.

[0041] Specifically, the output shaft of the fan 7 drives the upper connecting shaft 18 to rotate. The upper connecting shaft 18 drives the prism shaft 14 to rotate through the second transmission gear set 17, the inner rotating shaft 16 and the first transmission gear set 15. The prism shaft 14 drives the rotating disk 11 to rotate through the prism cylinder 13. The rotating disk 11 drives the fixed disk 10 to rotate through the pawl 12. The fixed disk 10 drives the shielding cylinder 9 to rotate, realizing the dislocation of the light-transmitting holes 901 and the Fresnel lens 8.

[0042] In this embodiment, the distance between adjacent Fresnel lenses 8 is greater than the diameter of the Fresnel lens 8.

[0043] Specifically, when the light-transmitting holes 901 and the Fresnel lens 8 are dislocated, the shielding cylinder 9 can completely cover the Fresnel lens 8, preventing light from entering the housing 1.

[0044] Please refer to Figure 5 , in this embodiment, the inner rotating shaft 16 is rotatably connected with a protective cylinder 19 sleeved outside the first transmission gear set 15 and the second transmission gear set 17. The protective cylinder 19 is fixedly connected to the inner wall of the housing 1 through a connecting rod integrally formed therewith.

[0045] Specifically, the installation and fixation of the first transmission gear set 15, the inner rotating shaft 16 and the second transmission gear set 17 are realized.

[0046] Please refer to Figure 8 , in this embodiment, the housing 1 is of a cylindrical structure. A water collecting cavity 101 is provided at the position of the housing 1 below the air inlet net 5. The water collecting cavity 101 is a conical cavity with the tip facing downwards. The water collecting cavity 101 is communicated with the liquid discharge pipe 6.

[0047] Specifically, it is convenient to collect the circulating liquid after heat exchange.

[0048] Please refer to Figure 8 In this embodiment, the packing cylinder 2 has a cylindrical structure. At the lower end of the packing cylinder 2, there is a bearing liquid leakage tray 20 fixedly connected to the inner wall of the housing 1. The bearing liquid leakage tray 20 is provided with uniformly distributed liquid leakage holes.

[0049] Specifically, it realizes the support and fixation of the packing cylinder 2 and facilitates the downward flow of the circulating liquid.

[0050] Please refer to Figure 5 and Figure 10 In another embodiment of the present invention, the liquid inlet pipe 4 includes a central pipe 401 passing through the central position of the packing cylinder 2. The upper end of the central pipe 401 is communicated with the spray pipe 3 through a rotary joint 21. The upper end of the spray pipe 3 is fixedly connected with a plug-in cylinder 22, and the prism shaft 14 is inserted into the plug-in cylinder 22.

[0051] Please refer to Figure 10 In this embodiment, the spray pipe 3 is fixedly connected with multiple groups of nozzles 301 distributed at equal intervals. The plug-in cylinder 22 is provided with a prism groove for inserting and holding the prism shaft 14.

[0052] Specifically, when the fan 7 drives the prism shaft 14 to rotate, the prism shaft 14 drives the spray pipe 3 to rotate in a circle through the plug-in cylinder 22, and uniformly sprays the circulating liquid on the packing cylinder 2, improving the uniformity and heat transfer efficiency of heat exchange.

[0053] Please refer to Figure 10 In this embodiment, the heat exchange cavity 201 is a rib-shaped cavity penetrating the packing cylinder 2, and the central pipe 401 is a vertical pipe made of a heat-conducting material.

[0054] Specifically, the rib-shaped heat exchange cavity 201 enables light to be fully refracted in the packing cylinder 2, so that the light not only conducts radiative heat transfer to the circulating liquid in the heat exchange cavity 201 but also conducts radiative heat transfer to the circulating liquid in the central pipe 401, improving the heat transfer efficiency.

[0055] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
