Description

Technical Field

[0001] This utility model belongs to the technical field of tower-type solar thermal collectors, specifically relating to a tower-type solar thermal collector that is easy to clean. Background Technology

[0002] A tower solar thermal collector is a device that uses concentrated solar power technology to convert solar energy into thermal energy. It is an important component of a tower solar thermal power generation system. In tower solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to produce high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0003] In practical applications, the surface of a tower-type solar thermal collector is exposed to the outdoors for a long time. Over time, various dust and other impurities will inevitably adhere to the surface of the tower, requiring cleaning by staff. However, due to the excessive height of the tower, cleaning is extremely inconvenient. Utility Model Content

[0014] As a further improvement to the technical solution of this utility model, the winding mechanism includes a placement groove opened at the bottom of the inner cavity of the support frame, a second motor is embedded in the inner cavity of the side wall of the placement groove, a winding rod is installed at the output end of the second motor, a sealing cloth is fixedly installed on the outside of the winding rod, and multiple sets of guide strips are fixedly installed on the surface of the sealing cloth.

[0015] As a further improvement to the technical solution of this utility model, the outer surface of the guide strip is slidably installed with the inner cavity of the corresponding sliding groove.

[0016] The beneficial effects of this utility model are: (1) The tower-type solar thermal collector of this utility model is easy to clean. It can collect rain and snow with the collection cover. When there is dirt on the surface of the tower-type solar thermal collector, the first motor can be started. The first motor will drive the steering rod to rotate.

[0023] Example 1 like Figures 1 to 3 As shown, the present invention provides a tower-type solar thermal collector that is easy to clean, comprising a tower-type solar thermal collector 1, a support frame 2 fixedly installed on the top of the tower-type solar thermal collector 1, a turning groove 3 opened on the outer side of the support frame 2, and a collection cover 7 for holding liquid rotatably arranged in the turning groove.

[0024] The tower-type solar thermal collector 1 mentioned here is an existing tower-type solar thermal collector. This tower-type solar thermal collector is a device that uses concentrating technology to convert solar energy into thermal energy. It is an important component of the tower-type solar thermal power generation system. In tower-type solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to generate high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0025] Compared with the prior art, in Embodiment 1, the improvement of the present invention, which provides an easy-to-clean tower-type solar thermal collector, is that a flip-up collection cover 7 is added to the top of the existing tower-type solar thermal collector.

[0026] In order to install the collection cover 7, a support frame 2 is first installed on the top of the tower solar thermal collector 1. Then, a turning groove for placing the collection cover 7 is opened on the side of the support frame 2. Finally, the collection cover 7 can be installed in the turning groove in a flip-up manner.

[0027] Therefore, in this easy-to-clean tower-type solar thermal collector, the functions of each component are as follows: The support frame 2 is used to form a support, serving as a basic support frame to bear the weight of the collection cover 7 and to install the collection cover 7.

[0028] The function of the collection cover 7 is to collect rain and snow in rainy or snowy weather. After collecting the rain and snow, the liquid in the collection cover 7 can be poured from the top of the tower solar thermal collector 1 by flipping the collection cover 7, so as to clean the surface of the tower solar thermal collector 1 and remove dust and other impurities attached to the surface of the tower solar thermal collector 1.

[0029] The present invention discloses an easy-to-clean tower-type solar thermal collector, the working principle of which is as follows: During rainy or snowy weather, rain and snow can be collected using the collection cover 7. When there is dirt on the surface of the tower-type solar thermal collector 1, the collection cover 7 can be flipped over. The flipped collection cover 7 will pour the liquid inside onto the top of the tower-type solar thermal collector 1. At this time, the liquid can wash the outside of the tower-type solar thermal collector 1, realizing the automatic cleaning function of the tower-type solar thermal collector 1. The entire cleaning process is simple and convenient, without the need for manual wiping, which not only greatly improves the efficiency of production operations, but also saves labor.

[0030] Example 2 like Figures 1 to 3 As shown in Embodiment 1, Embodiment 2 of this utility model, a tower-type solar thermal collector that is easy to clean, also includes a tower-type solar thermal collector 1. A support frame 2 is fixedly installed on the top of the tower-type solar thermal collector 1. A turning groove 3 is opened on the outside of the support frame 2. A collection cover 7 for holding liquid is rotatably arranged in the turning groove 3.

[0031] like Figure 1 As shown, unlike Embodiment 1, in Embodiment 2, a tower-type solar thermal collector of this utility model is provided with a first motor 4 in the steering groove 3, and the drive end of the first motor 4 is connected to a steering rod 5, and the collection cover 7 is connected to the steering rod 5.

[0032] Compared to Embodiment 1, Embodiment 2 provides a first method to drive the collection cover 7. The principle is to use a motor to flip the collection cover 7 to collect rain and snow, and then let the collected rain and snow fall from the tower-type solar thermal collector 1.

[0033] The following is a detailed description of a tower-type solar thermal collector of this utility model that is easy to clean, according to Embodiment 2.

[0034] The tower-type solar thermal collector 1 mentioned here is an existing tower-type solar thermal collector. This tower-type solar thermal collector is a device that uses concentrating technology to convert solar energy into thermal energy. It is an important component of the tower-type solar thermal power generation system. In tower-type solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to generate high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0035] Compared with the prior art, in Embodiment 2, the improvement of the easy-to-clean tower-type solar thermal collector of the present invention is that a flip-up collection cover 7 is added to the top of the existing tower-type solar thermal collector, and the method of flipping the collection cover 7 is defined.

[0036] In order to install the collection cover 7, a support frame 2 is first installed on the top of the tower solar thermal collector 1. Then, a turning groove 3 for placing the collection cover 7 is opened on the side of the support frame 2. Finally, the collection cover 7 can be installed in the turning groove 3 in a flip-up manner.

[0037] To ensure that the collection cover 7 can be flipped, the tower-type solar thermal collector of this utility model, which is easy to clean, is driven by a motor. Specifically, a first motor 4 is installed on the inner side of the turning groove 3, and a turning rod 5 is connected to the output shaft of the first motor 4. Finally, the turning rod 5 is fixedly connected to the collection cover 7.

[0038] In this way, controlling the forward and reverse rotation of the first motor 4 drives the steering rod 5 to rotate, which in turn drives the collection cover 7 to rotate as well. Specifically: when the first motor 4 rotates forward, the collection cover 7 will gradually close onto the top of the tower-type solar thermal collector 1, allowing the collected water to fall from the top of the tower-type solar thermal collector 1, thus playing a certain role in surface cleaning; when the first motor 4 rotates in reverse, the collection cover 7 will gradually move away from the top of the tower-type solar thermal collector 1 until the opening of the collection cover 7 is horizontal and rests on the edge of the support frame 2, at which point the first motor 4 will also stop rotating in reverse.

[0039] Therefore, in this easy-to-clean tower-type solar thermal collector, the functions of each component are as follows: The support frame 2 is used to form a support, serving as a basic support frame to bear the weight of the collection cover 7 and to install the collection cover 7.

[0040] The function of the collection cover 7 is to collect rain and snow in rainy or snowy weather. After collecting the rain and snow, the liquid in the collection cover 7 can be poured from the top of the tower solar thermal collector 1 by flipping the collection cover 7, so as to clean the surface of the tower solar thermal collector 1 and remove dust and other impurities attached to the surface of the tower solar thermal collector 1.

[0041] The function of the first motor 4 is to provide driving force to drive the collection cover 7 to flip. The steering rod 5 serves as a connector to connect the output shaft of the first motor 4 with the collection cover 7, transmitting the driving force of the first motor 4 to the collection cover 7 and enabling the collection cover 7 to flip.

[0042] This utility model discloses an easy-to-clean tower-type solar thermal collector, the working principle of which is as follows: During rainy or snowy weather, rain and snow can be collected using the collection cover 7. When there is dirt on the surface of the tower-type solar thermal collector 1, the first motor 4 can be started. The first motor 4 will drive the steering rod 5 to rotate. The rotating steering rod will drive the collection cover 7 to flip over. The flipped collection cover 7 will pour the liquid inside onto the top of the tower-type solar thermal collector 1. At this time, the liquid can wash the outside of the tower-type solar thermal collector 1, realizing the automatic cleaning function of the tower-type solar thermal collector 1. The whole cleaning process is simple and convenient, without the need for manual wiping, which not only greatly improves the efficiency of production operations, but also saves labor.

[0043] Example 3 like Figures 1 to 3 As shown in Example 1, Example 3 of this utility model also includes a tower-type solar thermal collector 1. A support frame 2 is fixedly installed on the top of the tower-type solar thermal collector 1. A turning groove 3 is opened on the outside of the support frame 2. A collection cover 7 for holding liquid is rotatably arranged in the turning groove 3.

[0044] like Figure 1 As shown, unlike Embodiment 1, in Embodiment 3 of this utility model, a first motor 4 is provided in the steering groove 3, the drive end of the first motor 4 is connected to a steering rod 5, the collection cover 7 is connected to the steering rod 5, and the steering rod 5 is rotatably arranged in the steering groove 3 through a pair of bearings.

[0045] Compared to Embodiment 1, Embodiment 3 provides a method to drive the collection cover 7. The principle is to use a motor to flip the collection cover 7 to collect rain and snow, and then let the collected rain and snow fall from the tower-type solar thermal collector 1.

[0046] Compared to Embodiment 1, Embodiment 3 also provides a method for installing the steering rod 5. The principle is to rotatably install the steering rod 5 inside the collection cover by a pair of bearings, so as to avoid bending when it is subjected to the large gravity of the collection cover 7 and to avoid radial runout during rotation.

[0047] The following is a detailed description of a tower-type solar thermal collector of this utility model that is easy to clean, according to Embodiment 3.

[0048] The tower-type solar thermal collector 1 mentioned here is an existing tower-type solar thermal collector. This tower-type solar thermal collector is a device that uses concentrating technology to convert solar energy into thermal energy. It is an important component of the tower-type solar thermal power generation system. In tower-type solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to generate high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0049] Compared with the prior art, in Embodiment 3, the improvement of the easy-to-clean tower-type solar thermal collector of this utility model lies in the following two aspects: 1) An inverted collection cover 7 was added to the top of the existing tower-type solar thermal collector, and a method for inverting the collection cover 7 was defined.

[0050] In order to install the collection cover 7, a support frame 2 is first installed on the top of the tower solar thermal collector 1. Then, a turning groove 3 for placing the collection cover 7 is opened on the side of the support frame 2. Finally, the collection cover 7 can be installed in the turning groove 3 in a flip-up manner.

[0051] To ensure that the collection cover 7 can be flipped, the tower-type solar thermal collector of this utility model, which is easy to clean, is driven by a motor. Specifically, a first motor 4 is installed on the inner side of the turning groove 3, and a turning rod 5 is connected to the output shaft of the first motor 4. Finally, the turning rod 5 is fixedly connected to the collection cover 7.

[0052] In this way, controlling the forward and reverse rotation of the first motor 4 drives the steering rod 5 to rotate, which in turn drives the collection cover 7 to rotate as well. Specifically: when the first motor 4 rotates forward, the collection cover 7 will gradually close onto the top of the tower-type solar thermal collector 1, allowing the collected water to fall from the top of the tower-type solar thermal collector 1, thus playing a certain role in surface cleaning; when the first motor 4 rotates in reverse, the collection cover 7 will gradually move away from the top of the tower-type solar thermal collector 1 until the opening of the collection cover 7 is horizontal and rests on the edge of the support frame 2, at which point the first motor 4 will also stop rotating in reverse.

[0053] 2) One assembly method for the steering rod 5 is specified.

[0054] Because the steering rod 5 has a certain length, if it is directly connected to the output shaft of the first motor 4 and then the collection cover 7 is connected to it, the steering rod 5 will bear a large force, causing it to deform. Therefore, a bearing can be installed at the front and rear of the steering rod 5 for rotational support. Specifically, the steering rod 5 is fixed to the inner ring of the bearing, while the outer ring of the bearing is fixed in the steering groove. With this design, when the steering rod 5 bears the large weight of the collection cover 7, the two bearings can support it and prevent it from bending or deforming, thus avoiding radial runout of the steering rod 5 when the first motor 4 rotates, which would affect the stability of rotation.

[0055] Therefore, in this easy-to-clean tower-type solar thermal collector, the functions of each component are as follows: The support frame 2 is used to form a support, serving as a basic support frame to bear the weight of the collection cover 7 and to install the collection cover 7.

[0056] The function of the collection cover 7 is to collect rain and snow in rainy or snowy weather. After collecting the rain and snow, the liquid in the collection cover 7 can be poured from the top of the tower solar thermal collector 1 by flipping the collection cover 7, so as to clean the surface of the tower solar thermal collector 1 and remove dust and other impurities attached to the surface of the tower solar thermal collector 1.

[0057] The function of the first motor 4 is to provide driving force to drive the collection cover 7 to flip. The steering rod 5 serves as a connector to connect the output shaft of the first motor 4 with the collection cover 7, transmitting the driving force of the first motor 4 to the collection cover 7 and enabling the collection cover 7 to flip.

[0058] A pair of bearings are used to enable the rotatable mounting of the steering rod 5, providing support for the steering rod 5 and ensuring that it can withstand a large amount of gravity while being rotatable.

[0059] This utility model discloses an easy-to-clean tower-type solar thermal collector, the working principle of which is as follows: During rainy or snowy weather, rain and snow can be collected using the collection cover 7. When there is dirt on the surface of the tower-type solar thermal collector 1, the first motor 4 can be started. The first motor 4 will drive the steering rod 5 to rotate. The rotating steering rod 5 will drive the collection cover 7 to flip over. The flipped collection cover 7 will pour the liquid inside onto the top of the tower-type solar thermal collector 1. At this time, the liquid can wash the outside of the tower-type solar thermal collector 1, realizing the automatic cleaning function of the tower-type solar thermal collector 1. The whole cleaning process is simple and convenient, without the need for manual wiping, which not only greatly improves the efficiency of production operations, but also saves labor.

[0060] Example 4 like Figures 1 to 3As shown in Example 1, Example 4 of this utility model also includes a tower-type solar thermal collector 1. A support frame 2 is fixedly installed on the top of the tower-type solar thermal collector 1. A turning groove 3 is opened on the outside of the support frame 2. A collection cover 7 for holding liquid is rotatably arranged in the turning groove 3.

[0061] like Figure 1 As shown, unlike Embodiment 1, in Embodiment 4 of this utility model, a tower-type solar thermal collector is provided in the steering groove 3, a first motor 4 is provided in the steering groove 3, the drive end of the first motor 4 is connected to a steering rod 5, the collection cover 7 is connected to the steering rod 5, the steering rod 5 is rotatably provided in the steering groove 3 through a pair of bearings, and a steering tube 6 is provided on the side of the collection cover 7, the steering tube 6 is fixedly fitted on the steering rod 5.

[0062] Compared to Embodiment 1, Embodiment 4 provides a method to drive the collection cover 7. The principle is to use a motor to flip the collection cover 7 to collect rain and snow, and then let the collected rain and snow fall from the tower-type solar thermal collector 1.

[0063] Compared to Embodiment 1, Embodiment 4 also provides a method for installing the steering rod 5. The principle is to rotatably install the steering rod 5 inside the collection cover by a pair of bearings, so as to avoid bending when it is subjected to the large gravity of the collection cover 7 and to avoid radial runout during rotation.

[0064] Compared to Embodiment 1, Embodiment 4 also provides an installation method for the collection cover 7. The principle is to first fix a steering tube 6 to the side of the collection cover 7, and then fix the steering tube 6 to the steering rod 5. This allows the collection cover 7 to be fixed on the steering rod 5, making installation more convenient.

[0065] The following is a detailed description of a tower-type solar thermal collector of this utility model that is easy to clean, according to Embodiment 4.

[0066] The tower-type solar thermal collector 1 mentioned here is an existing tower-type solar thermal collector. This tower-type solar thermal collector is a device that uses concentrating technology to convert solar energy into thermal energy. It is an important component of the tower-type solar thermal power generation system. In tower-type solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to generate high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0067] Compared with the prior art, in Embodiment 4, the improvement of the easy-to-clean tower-type solar thermal collector of this utility model lies in the following three points: 1) An inverted collection cover 7 was added to the top of the existing tower-type solar thermal collector, and a method for inverting the collection cover 7 was defined.

[0068] In order to install the collection cover 7, a support frame 2 is first installed on the top of the tower solar thermal collector 1. Then, a turning groove 3 for placing the collection cover 7 is opened on the side of the support frame 2. Finally, the collection cover 7 can be installed in the turning groove 3 in a flip-up manner.

[0069] To ensure that the collection cover 7 can be flipped, the tower-type solar thermal collector of this utility model, which is easy to clean, is driven by a motor. Specifically, a first motor 4 is installed on the inner side of the turning groove 3, and a turning rod 5 is connected to the output shaft of the first motor 4. Finally, the turning rod 5 is fixedly connected to the collection cover 7.

[0070] In this way, controlling the forward and reverse rotation of the first motor 4 drives the steering rod 5 to rotate, which in turn drives the collection cover 7 to rotate as well. Specifically: when the first motor 4 rotates forward, the collection cover 7 will gradually close onto the top of the tower-type solar thermal collector 1, allowing the collected water to fall from the top of the tower-type solar thermal collector 1, thus playing a certain role in surface cleaning; when the first motor 4 rotates in reverse, the collection cover 7 will gradually move away from the top of the tower-type solar thermal collector 1 until the opening of the collection cover 7 is horizontal and rests on the edge of the support frame 2, at which point the first motor 4 will also stop rotating in reverse.

[0071] 2) One assembly method for the steering rod 5 is specified.

[0072] Because the steering rod 5 has a certain length, if it is directly connected to the output shaft of the first motor 4 and then the collection cover 7 is connected to it, the steering rod 5 will bear a large force, causing it to deform. Therefore, a bearing can be installed at the front and rear of the steering rod 5 for rotational support. Specifically, the steering rod 5 is fixed to the inner ring of the bearing, while the outer ring of the bearing is fixed in the steering groove. With this design, when the steering rod 5 bears the large weight of the collection cover 7, the two bearings can support it and prevent it from bending or deforming, thus avoiding radial runout of the steering rod 5 when the first motor 4 rotates, which would affect the stability of rotation.

[0073] 3) Defines one way in which the collection cover 7 is mounted on the steering rod 5.

[0074] If the collection cover 7 is directly connected to the steering rod 5, it will affect the overall balance of the collection cover 7. Therefore, in embodiment 4, a steering tube 6 is welded to the side of the collection cover 7, and then the steering tube 6 is fitted onto the steering rod 5 and the two are fixed together. This design ensures that the collection cover 7 is easier to install and has relatively better balance, without requiring any changes to the overall structure of the collection cover 7.

[0075] Therefore, in this easy-to-clean tower-type solar thermal collector, the functions of each component are as follows: The support frame 2 is used to form a support, serving as a basic support frame to bear the weight of the collection cover 7 and to install the collection cover 7.

[0076] The function of the collection cover 7 is to collect rain and snow in rainy or snowy weather. After collecting the rain and snow, the liquid in the collection cover 7 can be poured from the top of the tower solar thermal collector 1 by flipping the collection cover 7, so as to clean the surface of the tower solar thermal collector 1 and remove dust and other impurities attached to the surface of the tower solar thermal collector 1.

[0077] The function of the first motor 4 is to provide driving force to drive the collection cover 7 to flip. The steering rod 5 serves as a connector to connect the output shaft of the first motor 4 with the collection cover 7, transmitting the driving force of the first motor 4 to the collection cover 7 and enabling the collection cover 7 to flip.

[0078] A pair of bearings are used to enable the rotatable mounting of the steering rod 5, providing support for the steering rod 5 and ensuring that it can withstand a large amount of gravity while being rotatable.

[0079] As a connecting component, the steering tube 6 can be installed on the steering rod 5 without changing the main structure of the collection bucket 7, ensuring good balance.

[0080] This utility model discloses an easy-to-clean tower-type solar thermal collector, the working principle of which is as follows: During rainy or snowy weather, rain and snow can be collected using the collection cover 7. When there is dirt on the surface of the tower-type solar thermal collector 1, the first motor 4 can be started. The first motor 4 will drive the steering rod 5 to rotate. The rotating steering rod 5 will drive the collection cover 7 to flip through the steering pipe 6. The flipped collection cover 7 will pour the internal liquid onto the top of the tower-type solar thermal collector 1. At this time, the liquid can wash the outside of the tower-type solar thermal collector 1, realizing the automatic cleaning function of the tower-type solar thermal collector 1. The whole cleaning process is simple and convenient, without the need for manual wiping, which not only greatly improves the efficiency of production operations, but also saves labor.

[0081] Example 5 like Figures 1 to 3 As shown in Example 1, Example 5 of this utility model also includes a tower-type solar thermal collector 1. A support frame 2 is fixedly installed on the top of the tower-type solar thermal collector 1. A turning groove 3 is opened on the outside of the support frame 2. A collection cover 7 for holding liquid is rotatably arranged in the turning groove 3.

[0082] like Figure 1As shown, unlike Embodiment 1, in Embodiment 5 of this utility model, a tower-type solar thermal collector is provided in the steering groove 3, a first motor 4 is provided in the steering groove 3, the drive end of the first motor 4 is connected to the steering rod 5, the collection cover 7 is connected to the steering rod 5, the steering rod 5 is rotatably provided in the steering groove 3 through a pair of bearings, the side of the collection cover 7 is provided with a steering tube 6, the steering tube 6 is fixedly fitted on the steering rod 5, and the outside of the support frame 2 is rectangular.

[0083] Compared to Embodiment 1, Embodiment 5 provides a method to drive the collection cover 7. The principle is to use a motor to flip the collection cover 7 to collect rain and snow, and then let the collected rain and snow fall from the tower-type solar thermal collector 1.

[0084] Compared to Embodiment 1, Embodiment 5 also provides a method for installing the steering rod 5. The principle is to rotatably install the steering rod 5 inside the collection cover by a pair of bearings, so as to avoid bending when it is subjected to the large gravity of the collection cover 7 and to avoid radial runout during rotation.

[0085] Compared to Embodiment 1, Embodiment 5 also provides an installation method for the collection cover 7. The principle is to first fix a steering tube 6 to the side of the collection cover 7, and then fix the steering tube 6 to the steering rod 5. This allows the collection cover 7 to be fixed on the steering rod 5, making installation more convenient.

[0086] Compared to Embodiment 1, Embodiment 5 also provides a support frame 2 with a rectangular outer shape, which can ensure installation stability and structural strength.

[0087] The following is a detailed description of a tower-type solar thermal collector of this utility model that is easy to clean, according to Embodiment 5.

[0088] The tower-type solar thermal collector 1 mentioned here is an existing tower-type solar thermal collector. This tower-type solar thermal collector is a device that uses concentrating technology to convert solar energy into thermal energy. It is an important component of the tower-type solar thermal power generation system. In tower-type solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to generate high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0089] Compared with the prior art, in Embodiment 5, the improvements of the easy-to-clean tower-type solar thermal collector of this utility model are as follows: 1) An inverted collection cover 7 was added to the top of the existing tower-type solar thermal collector, and a method for inverting the collection cover 7 was defined.

[0090] In order to install the collection cover 7, a support frame 2 is first installed on the top of the tower solar thermal collector 1. Then, a turning groove 3 for placing the collection cover 7 is opened on the side of the support frame 2. Finally, the collection cover 7 can be installed in the turning groove 3 in a flip-up manner.

[0091] To ensure that the collection cover 7 can be flipped, the tower-type solar thermal collector of this utility model, which is easy to clean, is driven by a motor. Specifically, a first motor 4 is installed on the inner side of the turning groove 3, and a turning rod 5 is connected to the output shaft of the first motor 4. Finally, the turning rod 5 is fixedly connected to the collection cover 7.

[0092] In this way, controlling the forward and reverse rotation of the first motor 4 drives the steering rod 5 to rotate, which in turn drives the collection cover 7 to rotate as well. Specifically: when the first motor 4 rotates forward, the collection cover 7 will gradually close onto the top of the tower-type solar thermal collector 1, allowing the collected water to fall from the top of the tower-type solar thermal collector 1, thus playing a certain role in surface cleaning; when the first motor 4 rotates in reverse, the collection cover 7 will gradually move away from the top of the tower-type solar thermal collector 1 until the opening of the collection cover 7 is horizontal and rests on the edge of the support frame 2, at which point the first motor 4 will also stop rotating in reverse.

[0093] 2) One assembly method for the steering rod 5 is specified.

[0094] Because the steering rod 5 has a certain length, if it is directly connected to the output shaft of the first motor 4 and then the collection cover 7 is connected to it, the steering rod 5 will bear a large force, causing it to deform. Therefore, a bearing can be installed at the front and rear of the steering rod 5 for rotational support. Specifically, the steering rod 5 is fixed to the inner ring of the bearing, while the outer ring of the bearing is fixed in the steering groove. With this design, when the steering rod 5 bears the large weight of the collection cover 7, the two bearings can support it and prevent it from bending or deforming, thus avoiding radial runout of the steering rod 5 when the first motor 4 rotates, which would affect the stability of rotation.

[0095] 3) Defines one way in which the collection cover 7 is mounted on the steering rod 5.

[0096] If the collection cover 7 is directly connected to the steering rod 5, it will affect the overall balance of the collection cover 7. Therefore, in embodiment 4, a steering tube 6 is welded to the side of the collection cover 7, and then the steering tube 6 is fitted onto the steering rod 5 and the two are fixed together. This design ensures that the collection cover 7 is easier to install and has relatively better balance, without requiring any changes to the overall structure of the collection cover 7.

[0097] 4) The support frame 2 has a rectangular design on the outside, which can ensure better stability and higher strength.

[0098] Therefore, in this easy-to-clean tower-type solar thermal collector, the functions of each component are as follows: The support frame 2 is used to form a support, serving as a basic support frame to bear the weight of the collection cover 7 and to install the collection cover 7. Its rectangular structure ensures good stability after installation and prevents shaking. At the same time, this structure also has better strength, is not easily damaged, and can be used for a long time with a long service life.

[0099] The function of the collection cover 7 is to collect rain and snow in rainy or snowy weather. After collecting the rain and snow, the liquid in the collection cover 7 can be poured from the top of the tower solar thermal collector 1 by flipping the collection cover 7, so as to clean the surface of the tower solar thermal collector 1 and remove dust and other impurities attached to the surface of the tower solar thermal collector 1.

[0100] The function of the first motor 4 is to provide driving force to drive the collection cover 7 to flip. The steering rod 5 serves as a connector to connect the output shaft of the first motor 4 with the collection cover 7, transmitting the driving force of the first motor 4 to the collection cover 7 and enabling the collection cover 7 to flip.

[0101] A pair of bearings are used to enable the rotatable mounting of the steering rod 5, providing support for the steering rod 5 and ensuring that it can withstand a large amount of gravity while being rotatable.

[0102] As a connecting component, the steering tube 6 can be installed on the steering rod 5 without changing the main structure of the collection bucket 7, ensuring good balance.

[0103] This utility model discloses an easy-to-clean tower-type solar thermal collector, the working principle of which is as follows: During rainy or snowy weather, rain and snow can be collected using the collection cover 7. When there is dirt on the surface of the tower-type solar thermal collector 1, the first motor 4 can be started. The first motor 4 will drive the steering rod 5 to rotate. The rotating steering rod 5 will drive the collection cover 7 to flip through the steering pipe 6. The flipped collection cover 7 will pour the internal liquid onto the top of the tower-type solar thermal collector 1. At this time, the liquid can wash the outside of the tower-type solar thermal collector 1, realizing the automatic cleaning function of the tower-type solar thermal collector 1. The whole cleaning process is simple and convenient, without the need for manual wiping, which not only greatly improves the efficiency of production operations, but also saves labor.

[0104] Example 6 like Figures 1 to 3As shown in Example 1, Example 6 of this utility model also includes a tower-type solar thermal collector 1, with a support frame 2 fixedly installed on the top of the tower-type solar thermal collector 1.

[0106] Compared to Embodiment 1, Embodiment 6 provides a method to drive the collection cover 7. The principle is to use a motor to flip the collection cover 7 to collect rain and snow, and then let the collected rain and snow fall from the tower-type solar thermal collector 1.

[0107] Compared to Embodiment 1, Embodiment 6 also provides a method for installing the steering rod 5. The principle is to rotatably install the steering rod 5 inside the collection cover by a pair of bearings, so as to avoid bending when it is subjected to the large gravity of the collection cover 7 and to avoid radial runout during rotation.

[0110] Compared to Embodiment 1, Embodiment 6 also provides a support frame 2 with multiple fixing rods 8 fixedly installed at the bottom, which can further support the support frame 2 and ensure its installation stability.

[0111] The following is a detailed description of a tower-type solar thermal collector of this utility model that is easy to clean, according to Embodiment 6.

On the one hand, this can strengthen the stability of the multiple retaining rods 8, and on the other hand, it can ensure that workers can climb up from the multiple sets of reinforcing frames 9.

[0166] Compared to Example 1, Example 8 also includes a winding mechanism 11, which works by using the winding mechanism 11 to enclose the closed fabric 1104 in the area where the worker is working, thus forming a protective barrier.

[0167] The following is a detailed description of a tower-type solar thermal collector of this utility model that is easy to clean, according to Embodiment 8.

[0168] The tower-type solar thermal collector 1 mentioned here is an existing tower-type solar thermal collector. This tower-type solar thermal collector is a device that uses concentrating technology to convert solar energy into thermal energy. It is an important component of the tower-type solar thermal power generation system. In tower-type solar thermal power generation, multiple heliostats form a heliostat field, which reflects and concentrates sunlight onto the receiver at the top of the tower. The receiver converts the received solar energy into thermal energy, which in turn heats the working fluid to generate high-temperature steam. This high-temperature steam can drive a steam turbine to rotate, thereby driving a generator to generate electricity.

[0169] Compared with the prior art, in Embodiment 8, the improvements of the easy-to-clean tower-type solar thermal collector of this utility model are as follows: 1) An inverted collection cover 7 was added to the top of the existing tower-type solar thermal collector, and a method for inverting the collection cover 7 was defined.

[0170] In order to install the collection cover 7, a support frame 2 is first installed on the top of the tower solar thermal collector 1. Then, a turning groove 3 for placing the collection cover 7 is opened on the side of the support frame 2. Finally, the collection cover 7 can be installed in the turning groove 3 in a flip-up manner.

[0171] To ensure that the collection cover 7 can be flipped, the tower-type solar thermal collector of this utility model, which is easy to clean, is driven by a motor. Specifically, a first motor 4 is installed on the inner side of the turning groove 3, and a turning rod 5 is connected to the output shaft of the first motor 4. Finally, the turning rod 5 is fixedly connected to the collection cover 7.

[0172] In this way, controlling the forward and reverse rotation of the first motor 4 drives the steering rod 5 to rotate, which in turn drives the collection cover 7 to rotate as well. Specifically: when the first motor 4 rotates forward, the collection cover 7 will gradually close onto the top of the tower-type solar thermal collector 1, allowing the collected water to fall from the top of the tower-type solar thermal collector 1, thus playing a certain role in surface cleaning; when the first motor 4 rotates in reverse, the collection cover 7 will gradually move away from the top of the tower-type solar thermal collector 1 until the opening of the collection cover 7 is horizontal and rests on the edge of the support frame 2, at which point the first motor 4 will also stop rotating in reverse.

[0173] 2) One assembly method for the steering rod 5 is specified.

[0174] Because the steering rod 5 has a certain length, if it is directly connected to the output shaft of the first motor 4 and then the collection cover 7 is connected to it, the steering rod 5 will bear a large force, causing it to deform. Therefore, a bearing can be installed at the front and rear of the steering rod 5 for rotational support. Specifically, the steering rod 5 is fixed to the inner ring of the bearing, while the outer ring of the bearing is fixed in the steering groove. With this design, when the steering rod 5 bears the large weight of the collection cover 7, the two bearings can support it and prevent it from bending or deforming, thus avoiding radial runout of the steering rod 5 when the first motor 4 rotates, which would affect the stability of rotation.

[0175] 3) Defines one way in which the collection cover 7 is mounted on the steering rod 5.

[0176] If the collection cover 7 is directly connected to the steering rod 5, it will affect the overall balance of the collection cover 7. Therefore, in embodiment 4, a steering tube 6 is welded to the side of the collection cover 7, and then the steering tube 6 is fitted onto the steering rod 5 and the two are fixed together. This design ensures that the collection cover 7 is easier to install and has relatively better balance, without requiring any changes to the overall structure of the collection cover 7.

[0177] 4) The support frame 2 is designed to be rectangular, which ensures better stability and higher strength.

[0178] 5) The bottom of the support frame 2 is fixedly installed with multiple fixing rods 8, which can further ensure that the support frame 2 is stably supported.

[0179] 6) Multiple sets of reinforcement frames 9 are fixedly installed inside the multiple fixing rods 8. On the one hand, this can strengthen the stability of the multiple fixing rods 8, and on the other hand, it can ensure that workers can climb up from the multiple sets of reinforcement frames 9.

[0180] 7) A winding mechanism 11 was added to close the sealing fabric 1104 in the area where the worker works, forming a protective barrier.

[0181] Therefore, in this easy-to-clean tower-type solar thermal collector, the functions of each component are as follows: The support frame 2 is used to form a support, serving as a basic support frame to bear the weight of the collection cover 7 and to install the collection cover 7. Its rectangular structure ensures good stability after installation and prevents shaking. At the same time, this structure also has better strength, is not easily damaged, and can be used for a long time with a long service life.

[0182] The function of the collection cover 7 is to collect rain and snow in rainy or snowy weather. After collecting the rain and snow, the liquid in the collection cover 7 can be poured from the top of the tower solar thermal collector 1 by flipping the collection cover 7, so as to clean the surface of the tower solar thermal collector 1 and remove dust and other impurities attached to the surface of the tower solar thermal collector 1.

[0183] The function of the first motor 4 is to provide driving force to drive the collection cover 7 to flip. The steering rod 5 serves as a connector to connect the output shaft of the first motor 4 with the collection cover 7, transmitting the driving force of the first motor 4 to the collection cover 7 and enabling the collection cover 7 to flip.

[0184] A pair of bearings are used to enable the rotatable mounting of the steering rod 5, providing support for the steering rod 5 and ensuring that it can withstand a large amount of gravity while being rotatable.

[0185] As a connecting component, the steering tube 6 can be installed on the steering rod 5 without changing the main structure of the collection bucket 7, ensuring good balance.

[0186] The retaining rod 8 is used to support the support frame 2, ensuring better stability of the support frame 2.

[0187] The reinforcement frame 9 is used to enhance the stability between the retaining rods 8, and at the same time facilitates workers' climbing.

[0188] The winding mechanism 11 is used to close the sealing fabric 1104 in the area where the worker is working to form protection.

[0189] This utility model discloses an easy-to-clean tower-type solar thermal collector, the working principle of which is as follows: During rainy or snowy weather, rain and snow can be collected using the collection cover 7. When there is dirt on the surface of the tower-type solar thermal collector 1, the first motor 4 can be started. The first motor 4 will drive the steering rod 5 to rotate. The rotating steering rod 5 will drive the collection cover 7 to flip through the steering pipe 6. The flipped collection cover 7 will pour the internal liquid onto the top of the tower-type solar thermal collector 1. At this time, the liquid can wash the outside of the tower-type solar thermal collector 1, realizing the automatic cleaning function of the tower-type solar thermal collector 1. The entire cleaning process is simple and convenient, requiring no manual wiping, which not only greatly improves the efficiency of production operations but also saves labor. In addition, when maintenance is needed, workers can climb up from the reinforcement frame 9 to carry out maintenance.

[0190] When hail occurs or when surface maintenance of the tower-type solar thermal collector 1 is required, the second motor 1102 can be started by powering on. The second motor 1102 will drive the winding rod 1103 to rotate. The rotating winding rod 1103 will drive the sealing cloth 1104 to move downwards. While the sealing cloth 1104 moves downwards, it will also slide inside the sliding groove 10 through the guide strip 1105. The cooperation between the guide strip 1105 and the sliding groove 10 ensures the stability of the movement of the sealing cloth 1104 and also prevents air from escaping. The airflow causes the sealing cloth 1104 to shake violently. Finally, the first motor 4 is started to drive the steering rod 5 to rotate. Then, the steering pipe 6 drives the collection cover 7 to seal the top of the tower solar thermal collector 1. This forms a closed space for the tower solar thermal collector 1. In the event of hail or other weather conditions, this can isolate the collector from hail. At the same time, it can prevent workers from being disturbed by strong winds when climbing to the high position of the tower solar thermal collector 1 during maintenance, thus improving the safety of workers during maintenance.
