Description

Technical Field

[0001] This application relates to the field of water turbine technology, and in particular to a gantry-type river hydroelectric generator set. Background Technology

[0002] my country is rich in water resources. In addition to large rivers and reservoirs, there are numerous irrigation canals, drainage ditches, and small streams, some only a few meters wide, widely distributed in urban and rural areas. These small waterways typically have a certain flow velocity and water level difference, and contain considerable hydropower potential.

[0003] However, traditional hydropower equipment usually requires damming or constructing complex hydraulic structures, which not only results in high investment costs and long construction periods but may also cause irreversible damage to the ecological environment. As a result, the hydropower resources of these small channels have not been effectively utilized for a long time. There are already some small hydropower devices on the market, but such power generation structures are complex to install and require fixed foundations or underwater construction, making them difficult to deploy quickly in ordinary channels. At the same time, the water depth of small waterways may vary depending on the season and rainfall, which leads to unstable power generation efficiency of traditional small hydropower devices. Some hydropower devices also need to be installed in the water or require damming, which affects the ecological environment of the waterway. Therefore, how to solve the above problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a gantry-type river hydroelectric generator set to solve one of the above-mentioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a gantry-type river hydroelectric generator set, comprising: a gantry frame, including a crossbar set at the top, fixedly installed on the ground; a turbine assembly, at least one set of which is mounted on the gantry frame, the turbine assembly including a turbine runner and a turbine frame, the turbine runner being rotatably mounted on the turbine frame, one end of the turbine frame being hinged to the gantry frame; an adjusting traction device, one end of which is mounted on the crossbar and the other end connected to the turbine assembly, capable of adjusting the traction length, the turbine runner having different drafts depending on the traction length of the adjusting traction device; and a power generation assembly, which is drivenly connected to the turbine assembly and capable of converting the mechanical energy of the turbine runner into electrical energy.

[0007] In some embodiments, an angle locking assembly is further included, which includes a locking seat, a fixed sleeve, and a movable rod. The locking seat is fixedly mounted on the gantry frame, the fixed sleeve is rotatably mounted on the locking seat, one end of the movable rod is rotatably mounted on the turbine frame, and the movable rod always slides within the fixed sleeve. The fixed sleeve is capable of locking the position of the movable rod.

[0008] In some embodiments, the fixed sleeve is provided with an adjusting bolt, and the fixed sleeve is locked by the friction between the adjusting bolt and the movable rod.

[0009] In some embodiments, a pulley is provided on one side of the turbine runner and on one side of the power generation component, and the pulley is used to transmit mechanical energy to the power generation component.

[0010] In some embodiments, bearing housings are provided on both sides of the turbine runner, with one bearing housing located at the axial gap between the pulley and the turbine runner.

[0011] In some embodiments, the adjusting traction device is any one of an electric hoist, a hand chain hoist, a winch, or a winding machine.

[0012] In some embodiments, the turbine frame is provided with a turbine runner cover on the turbine runner.

[0013] In some embodiments, the gantry can accommodate multiple turbine components depending on the width of the crossbars.

[0014] In some embodiments, the gantry frame is fixed to the ground by feet.

[0015] The beneficial effects of this application are as follows: by adjusting the traction device, the angle of the turbine component hinged to the gantry can be controlled, so that the turbine runner can be lowered or increased in horizontal height, thereby affecting the draft of the turbine runner. Its structure is simple and easy to install. At the same time, the gantry does not require dam construction or alteration of the river structure, does not affect the natural flow of water and the ecological environment, and is easy to transport. After assembly, the structure is simple and has good integrity. During the installation of the unit, the installation accuracy can be well controlled to ensure that the concentricity and levelness of the turbine shaft meet the requirements, and reduce vibration caused by installation errors.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0023] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a gantry-type river hydroelectric generator set, mainly comprising: a gantry 1, including a crossbar 11 set at the top, fixedly installed on the ground; a turbine assembly 2, at least one set of which is installed on the gantry 1, the turbine assembly 2 including a turbine runner 21 and a turbine frame 22, the turbine runner 21 being rotatably mounted on the turbine frame 22, one end of the turbine frame 22 being hinged to the gantry 1; an adjusting traction device 3, one end of which is set on the crossbar 11, the other end of which is connected to the turbine assembly 2, and capable of adjusting the traction length, the turbine runner 21 having different drafts depending on the different traction lengths of the adjusting traction device 3; and a power generation component 4, which is drivenly connected to the turbine assembly 2 and capable of converting the mechanical energy of the turbine runner 21 into electrical energy.

[0024] Specifically, when a hydroelectric generator set needs to be installed, a gantry frame 1 is fixedly installed on the riverbank and a corresponding number of turbine components 2 are hinged on it according to the width of the water surface. This allows the turbine runner 21 to swing at a certain angle. One end of the traction device 3 is connected to the crossbar 11, and the other end is connected to the turbine frame 22. Therefore, by controlling and adjusting the connection length of the traction device 3, the horizontal height of the turbine runner 21 can be changed, and the draft of the turbine runner 21 can be changed.

[0025] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0026] Specifically, to prevent the turbine runner 21 from changing its horizontal height due to water flow or buoyancy, thus affecting its draft and power generation efficiency, an angle locking assembly 5 is included. This assembly comprises a locking seat 51, a fixed sleeve 52, and a movable rod 53. The locking seat 51 is fixedly mounted on the gantry frame 1, the fixed sleeve 52 is rotatably mounted on the locking seat 51, and one end of the movable rod 53 is rotatably mounted on the turbine frame 22, with the movable rod 53 always sliding within the fixed sleeve 52. The fixed sleeve 52 locks the position of the movable rod 53. An adjusting bolt 521 is provided on the fixed sleeve 52, and the fixed sleeve 52 achieves locking by adjusting the friction between the adjusting bolt 521 and the movable rod 53. In summary, although the angle locking assembly 5 also has the function of adjusting the yaw angle of the turbine assembly 2, its effectiveness is poor; therefore, it needs to be used as a locking mechanism in conjunction with the adjusting traction mechanism.

[0027] For illustrative purposes, the above embodiments are merely examples of a common fitting method. However, those skilled in the art should know that the components provided on the fixed sleeve 52 can take many forms as long as they can prevent the movable rod 53 from shifting.

[0028] Specifically, in order to transmit the mechanical energy of the water turbine, a pulley 41 is provided on one side of the water turbine runner 21 and on one side of the power generation component 4 for mutual transmission. The pulley 41 is used to transmit mechanical energy to the power generation component 4.

[0029] Preferably, bearing housings 211 are provided on both sides of the turbine runner 21, one of which is located at the axial gap between the pulley 41 and the turbine runner 21. The bearing housing 211 is exposed to the outside, which ensures that the bearing is well lubricated and cooled during operation, reduces the bearing temperature and wear, extends the bearing service life, and improves the operational stability of the unit.

[0030] Preferably, the adjusting traction device 3 is any one of an electric hoist, a hand chain hoist, a winch, or a winding machine. For illustrative purposes, the above embodiments only list some common configurations; in specific applications, a suitable adjusting traction device 3 can be selected based on factors such as cost and terrain, and is not limited to the centralized adjusting device described above.

[0031] Preferably, in order to prevent external factors from affecting the normal operation of the turbine, the turbine frame 22 is provided with a turbine runner cover 212 on the turbine runner 21.

[0032] Figure 3 As shown, the gantry frame 1 can install multiple sets of water turbine components 2 depending on the width of the crossbar 11, and the width of the crossbar 11 can be determined according to the width of the waterway at the implementation location.

[0033] Preferably, in order to stably fix the gantry frame 1 to the ground, the gantry frame 1 is fixedly set on the ground by foot 12.

[0034] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
