[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0045] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0046] Example 1

[0047] Reference Figure 1-Figure 3 , this embodiment provides a concentrated photovoltaic power generation heat collecting tube.

[0048] The concentrated photovoltaic power generation heat collecting tube comprises a heat collecting tube mechanism 100 .

[0049] Specifically, the heat collecting tube mechanism 100 includes a tube body 101, both ends of which are movably sleeved with driving members 102, and the outer sides of the two driving members 102 are provided with tube seats 103 for connecting with the tube body 101, and at the same time, the inner walls at both ends of the tube body 101 are integrally provided with horizontal guide edges 104, and the inner side of the driving member 102 is also provided with a connecting member 105 for connection.

[0050] Furthermore, the driving member 102 includes a driving ring 102a movably sleeved on the end of the tube body 101, and a driving groove 102b is also reserved on the inner wall of the driving ring 102a.

[0051] The connecting piece 105 includes a connecting head tube 105a located on the inner side of the driving ring 102a. A guide groove 105b that can cooperate with the guide edge 104 is left at one end of the outer wall of the connecting head tube 105a. The rotation of the connecting head tube 105a can be restricted by the matching setting between the guide edge 104 and the guide groove 105b, ensuring that the connecting head tube 105a can only perform axial horizontal movement so as to be smoothly inserted into the tube seat 103, and a moving column 105c is integrally provided in the middle section of the connecting head tube 105a.

[0052] Preferably, the driving groove 102b is arranged in a spiral shape, and the moving column 105c can be slidably embedded in the driving groove 102b, so that when the driving ring 102a rotates, the driving groove 102b wall pushes the moving column 105c, so that the connecting head tube 105a is telescopically moved about the tube seat 103 under the cooperation of the guide groove 105b and the guide edge 104, and is linked with the driving ring 102a, thereby realizing the connection and disassembly between the tank body and the tube seat 103.

[0053] Example 2

[0054] Reference Figure 1-Figure 4 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0055] The heat collecting tube structure 100 further includes a closing member 106 disposed outside the connecting member 105 .

[0056] Specifically, the closure member 106 includes a movable ring 106a sleeved on the outside of the connecting head pipe 105a, and the movable ring 106a is located inside the pipe seat 103. The inner wall of the movable ring 106a is provided with a push groove 106b, and the outer wall of the connecting head pipe 105a is also fixedly provided with a push column 105d, and the push column 105d can cooperate with the push groove 106b. At the same time, a plurality of slide grooves 106c are provided at equal angles on the end surface of the movable ring 106a, and the interiors of the plurality of slide grooves 106c can be slidably embedded with slide columns 106d. The slide columns 106 d can slide inside the slide groove 106c, and the outer side of each slide column 106d is integrally connected with a closing piece 106e, and the surfaces of multiple closing pieces 106e are also provided with positioning grooves 106f. At the same time, a positioning block 103a matching the positioning groove 106f is arranged inside the tube seat 103, so that the positioning block 103a can limit the movement trajectory of the closing piece 106e in the positioning groove 106f, so that the closing piece 106e can only move along the straight line where the positioning block 103a and the center of the movable ring 106a are located.

[0057] Furthermore, the middle section of the push groove 106b is arranged in a spiral shape and tilted, and the two ends of the push groove 106b are arranged in horizontal grooves, so that the push column 105d on the outer wall of the connecting head tube 105a can be translated into the push groove 106b through the groove of the push groove 106b, and act on the middle section of the push groove 106b arranged in a spiral shape and tilted, so that the movable ring 106a can rotate with the insertion of the connecting head tube 105a, thereby realizing the subsequent transmission control of the closing piece 106e.

[0058] Preferably, the slide groove 106c is arranged in an arc shape along the radial direction of the movable ring 106a, that is, the distances between one end of the slide groove 106c and the other end from the center of the movable ring 106a are not equal, so that when the movable ring 106a rotates with the insertion of the connecting head tube 105a, the slide groove 106c can act on the sliding column 106d to drive the closing piece 106e restricted by the positioning block 103a to move in the opposite direction of the center of the movable ring 106a, thereby facilitating the complete insertion of the connecting head tube 105a, and the closing piece 106e is arranged in a fan shape formed by equally dividing a circular surface, so that when the connecting head tube 105a is pulled out, with the synchronous movement of multiple closing pieces 106e toward the center of the circle, when the vertices coincide at the center of the circle, they can be spliced ​​together to form a complete circular surface, thereby realizing the sealing of the tube seat 103 and preventing external impurities from entering the tube seat 103 or the liquid in the tube seat 103 from leaking out.

[0059] Example 3

[0060] Reference Figure 1-Figure 6 , which is the third embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0061] A transmission member 107 is embedded in the tube base 103 , and a locking member 108 is disposed on the outer side of the transmission member 107 .

[0062] Specifically, the transmission member 107 includes a top block 107a movably arranged inside the tube seat 103, a connecting spring 107b is arranged on the outside of the top block 107a, the other end of the connecting spring 107b is connected to the movable block 107c, and a return spring 107d is also arranged on the outside of the top block 107a. The top block 107a can be quickly reset under the elastic support of the return spring 107d.

[0063] The locking member 108 includes a base 108a fixed to the outside of the movable block 107c, a pop-up spring 108b is arranged inside the base 108a, and a clamp 108c for limiting the connector pipe 105a is connected to the outside of the pop-up spring 108b.

[0064] Furthermore, a push piece 106g is provided on the outer side of the movable ring 106a, and the top end of the push piece 106g is inclined. At the same time, the top block 107a is located on the rotation path of the push piece 106g, so that when the push piece 106g rotates with the movable ring 106a, it can gradually contact the top block 107a, thereby pushing the top block 107a out, and the locking piece 108 can realize the position locking of the connecting head tube 105a.

[0065] The outer wall of the connector tube 105a is also provided with a bayonet 105e that matches the clamp head 108c. The clamp head 108c can be clamped into the bayonet 105e under the action of the pop-up spring 108b, thereby limiting the connector tube 105a and preventing the connector tube 105a from being disconnected from the tube seat 103. At the same time, the bayonet 105e and the clamp head 108c are arranged opposite to each other at an angle, so that when the driving member 102 moves toward the tube seat 103, the bayonet 105e can squeeze the clamp head 108c, and at the same time, the movable block 107c and the top block 107a are connected by the connecting spring 107b. b is connected, and the connecting spring 107b has a certain deformation ability, so that when the clamping head 108c is squeezed by the bayonet 105e, the movable block 107c can swing to make the locking piece 108 retract into the tube seat 103, so that the restriction on the connecting head tube 105a disappears, and the disconnection need between the connecting head tube 105a and the tube seat 103 can be met. At the same time, a stop spring 109 is connected between the driving member 102 and the tube body 101, and the stop spring 109 can prevent the driving member 102 from moving toward the tube seat 103 by itself and affecting the stable connection between the connecting head tube 105a and the tube seat 103.

[0066] When the connection between the tube seat 103 and the tube body 101 is being made, the closing piece 106 is in a closed state, the tube body 101 is moved between the two tube seats 103 by external hoisting, and after the driving piece 102 is aligned with the tube seat 103, the driving ring 102a is rotated to make the connecting head tube 105a extend into the tube seat 103, and as the connecting head tube 105a extends, the push column gradually moves into the push groove 106b, thereby pushing the movable ring 106a to rotate, and through the transmission of the movable ring 106a, each closing piece 106e moves outward, and the movable ring 106a is opened before the connecting head tube 105a extends out of the movable ring 106a, and at the same time, as the movable ring 106a rotates, the top block 107a is lifted up , so that after the connecting head tube 105a moves into place, the clamping head 108c can be smoothly inserted into the bayonet 105e, thereby completing the connection between the tube seat 103 and the tube body 101 bracket. When the tube body 101 is disassembled, the movable driving ring 102a can squeeze the stop spring 109, and as the driving ring 102a moves parallel, the bayonet 105e squeezes the clamping head 108c, so that the clamping head 108c moves into the tube seat 103 and offsets the outward movement path of the bayonet 105e. Then the user can reversely rotate the driving ring 102a again to move the connecting head tube 105a outward, completing the disassembly between the tube seat 103 and the tube body 101, and while it moves outward, the closure 106 is closed again. Through the coordinated arrangement of the driving member 102, the connecting member 105, the closing member 106, the transmission member 107 and the locking member 108, the loading and unloading locking and unlocking between the tube seat 103 and the tube body 101 can be realized by operating the driving ring 102a, and the tube seat 103 is sealed by the closing member 106 to prevent external impurities from entering the tube seat 103, thereby ensuring the stable installation of the heat collecting tube and improving the performance and reliability of the component. At the same time, the disassembly and replacement of the tube body 101 is also more convenient, reducing the user's daily maintenance cost.

[0067] Example 4

[0068] Reference Figure 1-Figure 8 , which is the fourth embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0069] The concentrated photovoltaic power generation heat collecting tube also includes an auxiliary plug-in mechanism 200 .

[0070] Specifically, the auxiliary plug-in mechanism 200 is symmetrically arranged with respect to the tube body 101, and the auxiliary plug-in mechanism 200 includes a positioning support plate 201 fixed to the outside of the tube seat 103, and the top surface of the positioning support plate 201 is arranged in an arc-shaped surface, which can cooperate with the bottom of both ends of the tube body 101 to support and fix the tube body 101, so as to facilitate the hoisting and positioning of the tube body 101 and the subsequent connection with the tube seat 103, and a power part 202 is arranged inside the positioning support plate 201, and a pin locking part 203 is arranged on the outside of the power part 202, and a driven gear ring 204 is also arranged on the outside of the power part 202.

[0071] Furthermore, the power part 202 includes a transmission tooth 202a rotatably embedded in the positioning support plate 201, and a torsion spring sheet 202b is fixedly connected to the periphery of the protruding portion of the transmission tooth 202a, and the other end of the torsion spring sheet 202b is fixed to the inner wall of the positioning support plate 201, so that the transmission tooth 202a can be driven to rotate by the elastic deformation of the torsion spring sheet 202b, and at the same time, a positioning tooth 202c is coaxially fixedly installed on one end face of the transmission tooth 202a.

[0072] The pin lock 203 includes a pin 203a located on the outside of the positioning tooth 202c, and the pin 203a can be engaged with the outer tooth portion of the positioning tooth 202c to limit the rotation of the transmission tooth 202a through the engagement of the pin 203a and the positioning tooth 202c, and a socket 203b is provided inside the pin 203a, and a support spring 203c is provided on one end face of the pin 203a. The support spring 203c is located between the pin 203a and the inner wall of the positioning support plate 201, and can elastically support the pin 203a to ensure that the pin 203a in the contracted state can be quickly reset, and at the same time, a pressure rod 203d is inserted into the socket 203b.

[0073] Preferably, the socket 203b is wedge-shaped, and the corresponding inclined surface inside can cooperate with the pressure rod 203d, so that when the pressure rod 203d moves downward due to the pressure of the tube body 101, the lower end of the pressure rod 203d can squeeze the inclined surface on one side of the socket 203b, so that the pin 203a moves in the horizontal direction and squeezes the support spring 203c, and the pin 203a is disengaged from the positioning tooth 202c, thereby achieving the purpose of releasing the rotation restriction of the transmission tooth 202a, so that the transmission tooth 202a can rotate under the elastic force of the torsion spring sheet 202b.

[0074] Furthermore, the transmission tooth 202a and the driven gear ring 204 are in meshing cooperation, that is, when the transmission tooth 202a rotates under the elastic force of the torsion spring sheet 202b, the driven gear ring 204 can be driven to rotate synchronously by meshing with the driven gear ring 204. At the same time, the driven gear ring 204 is fixedly sleeved on the outside of the driving ring 102a, so that the rotation of the driving ring 102a can be controlled by the rotation of the transmission tooth 202a, and then the power storage through the torsion spring sheet 202b can be realized. Under the linkage cooperation of the transmission tooth 202a, the driven gear ring 204 and the driving ring 102a, the purpose of automatically extending the connecting head pipe 105a is achieved, making the plug-in between the tube body 101 and the tube seat 103 more convenient.

[0075] During the hoisting process of the tube body 101, when the tube body 101 is hoisted onto the surface of the positioning support plate 201 and the driven gear ring 204 on the outer periphery of the tube body 101 is located in the groove on the surface of the positioning support plate 201, the pressure rod 203d higher than the surface of the positioning support plate 201 moves downward under the pressure of the tube body 101, and gradually squeezes the inclined surface of one side of the socket 203b through its lower end, so that the pin 203a moves in the horizontal direction and disengages from the engagement with the positioning tooth 202c. At this time, the rotation restriction of the transmission tooth 202a is released, and the power stored in the torsion spring 202b is released, and through the meshing cooperation between the transmission tooth 202a and the driven gear ring 204, the transmission tooth 202a drives the drive ring 102a to rotate, thereby achieving the purpose of automatically extending the connecting head pipe 105a. When the connecting head pipe 105a needs to be retracted, the drive ring 102a is rotated in the opposite direction. The driving ring 102a, with the cooperation of the driven gear ring 204 and the transmission tooth 202a, drives the transmission tooth 202a to rotate in the opposite direction. While the transmission tooth 202a rotates, the torsion spring 202b is gradually tightened to store power. When the connecting head tube 105a is fully retracted to lift the tube body 101, the pressure on the pressure rod 203d disappears. The pin 203a can be reset and engaged with the positioning tooth 202c again under the elastic force of the supporting spring 203c, so as to limit the transmission tooth 202a to ensure its subsequent normal use. Through the transmission cooperation between the power piece 202, the pin lock piece 203 and the driven gear ring 204, the tube body 101 can be positioned and the automatic control of the plug-in between the tube body 101 and the tube seat 103 can be realized, so that the lifting and placement of the tube body 101 is more accurate and efficient.
