[0028] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Secondly, the so-called "one embodiment" or "embodiment" refers to specific features, structures or characteristics that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0030] Embodiment 1

[0031] Refer to Figure 1 and Figure 2 , which is the first embodiment of the present invention. This embodiment provides a thermal insulation and ice melting equipment for transmission towers in cold regions and its construction method. The thermal insulation and ice melting equipment for transmission towers in cold regions includes a thermal insulation component 100 and an installation component 200. The thermal insulation component 100 has the effect of heating and warming the transmission tower, melting the accumulated snow and ice on its top, improving the safety of the transmission tower during use. At the same time, the installation component 200 improves the disassembly and assembly efficiency of the equipment. When the climbers install and maintain the equipment, they do not need to carry too many tools, and the construction efficiency and safety are both higher.

[0032] Specifically, the thermal insulation component 100 includes a transmission tower support 101, a transfer box 102, a connecting pipe 103, a first heat exchange pipe 104, an installation pipe 105, a second heat exchange pipe 106 and a connecting pipe 107. The transfer box 102 is arranged on the top of the transmission tower support 101. The connecting pipe 103 is fixed to the bottom of the transfer box 102. An installation hole S is provided on the transmission tower support 101. The connecting pipe 103 is located in the installation hole S. The first heat exchange pipe 104 is communicated with the connecting pipe 103. The installation pipe 105 is fixed to the side of the transfer box 102. The second heat exchange pipe 106 is located in the installation pipe 105. The connecting pipe 107 is fixed in the transfer box 102 and is communicated with the connecting pipe 103 and the installation pipe 105.

[0033] The adapter box 102 is used to fix the heat exchange pipes of the adapter. The connecting pipe 103 is arranged based on the extended position of the transmission tower support 101 and is used to guide and fix the second heat exchange pipe 106. The first heat exchange pipe 104 and the installation pipe 105 are fixed at the bottom of the adapter box 102. The first heat exchange pipe 104 is connected to an external ground source heat pump and conveys the hot water from the heat exchange of the ground source heat pump into the second heat exchange pipe 106. Since there will be no snow accumulation in the vertical direction, a layer of thermal insulation material is coated on the surface of the first heat exchange pipe 104 during construction to prevent excessive heat loss when the hot water is conveyed upward, which may affect the snow and ice removal efficiency. The connecting pipe 107 is used to connect the first heat exchange pipe 104 and the second heat exchange pipe 106 to facilitate the conveyance of hot water to the second heat exchange pipe 106. Moreover, the first heat exchange pipe 104, the second heat exchange pipe 106 and the ground source heat pump form a water circulation system (not shown in the figure). The specific installation position can be set as required by those skilled in the art. This is prior art and will not be elaborated here.

[0034] The installation assembly 200 is arranged on the connecting pipe 103 and includes a movable pipe 201, a fastener 202, a fixing ring 203, a convex block 204, a receiving plate 205, a seal 206, a guiding plate 207, a pre-tightening member 208 and an installation member 209. The movable pipe 201 slides on the surface of the connecting pipe 103. The fastener 202 is arranged on the movable pipe 201 and is located within the installation hole S. The fixing ring 203 is fixed on the surface of the first heat exchange pipe 104. The convex block 204 is fixed around the fixing ring 203. A track P matching therewith is formed at the bottom of the movable pipe 201. The receiving plate 205 is fixed on the inner wall of the connecting pipe 103. The seal 206 is arranged at the end of the first heat exchange pipe 104. The guiding plate 207 is fixed on both sides of the second heat exchange pipe 106. The pre-tightening member 208 is arranged on both sides of the installation pipe 105. The installation member 209 cooperates with the pre-tightening member 208.

[0035] The movable pipe 201 is sleeved on the surface of the connecting pipe 103. Limit rods are fixed around the connecting pipe 103, and the movable pipe 201 slides on the limit rods to limit it and prevent it from shifting or rotating during the up-and-down movement. The fastener 202 is used to fix this mechanism on the transmission tower bracket 101, and without excessive screws, etc., greatly improving the construction efficiency of the staff. The fixing ring 203 and the convex block 204 are used to drive the movable pipe 201 to move downward during installation for fastening operation, and the fixation can be completed only by the weight of the first heat exchange pipe 104 itself. There are at least four receiving plates 205, evenly distributed on the inner wall of the connecting pipe 103. The seal 206 is used to seal the connecting pipe 103 and the first heat exchange pipe 104 to prevent water leakage. The guide plate 207 is used to guide the second heat exchange pipe 106, and a corresponding guide groove is provided on the inner wall of the installation pipe 105 to improve the installation efficiency of the second heat exchange pipe 106. The pre-tightening member 208 performs a pre-tightening operation during the installation of the second heat exchange pipe 106, and then the installation member 209 further fastens the second heat exchange pipe 106 to complete the installation.

[0036] Embodiment 2

[0037] Refer to Figures 1 to 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the fastener 202 includes a first rotating plate 202a, a second rotating plate 202b, and a support plate 202c. Through holes K are provided around the movable pipe 201. The first rotating plate 202a is rotatably connected to the inner wall of the through hole K, the second rotating plate 202b is rotatably connected to the outside of the connecting pipe 103, and the support plate 202c is rotatably connected to the ends of the two rotating plates.

[0039] There are at least four groups of fasteners 202, evenly distributed around the movable pipe 201. When the movable pipe 201 moves up and down, it can drive the first rotating plate 202a to move. Thus, when the first rotating plate 202a approaches or moves away from the second rotating plate 202b, it can drive the support plate 202c to move outward or inward, so as to fasten the adapter box 102 through the frictional force and supporting force between the support plate 202c and the inner wall of the installation hole S. And because the downward movement of the movable pipe 201 is driven by the pulling of the convex block 204 and the weight of the first heat exchange pipe 104 itself, the installation is more stable, and the staff does not need to carry too many installation devices, with higher safety.

[0040] The fastener 202 further includes a limit ring 202d and a first spring 202e. The limit ring 202d is fixed on the surface of the connecting pipe 103, and the two ends of the first spring 202e are respectively fixed to the limit ring 202d and the movable pipe 201.

[0041] The first spring 202e applies an upward pulling force to the movable pipe 201. When the bump 204 disengages from the track P, the first spring 202e pulls the movable pipe 201 back to its original position, which can make the support plate 202c move away from the inner wall of the mounting hole S. At this time, the adapter box 102 can be removed.

[0042] The seal 206 includes a convex plate 206a, a baffle 206b, a connecting rod 206c, a pressing ring 206d, a sealing ring 206e, and a mounting ring 206f. The convex plate 206a is fixed around the top of the first heat exchange pipe 104, and an installation groove V is formed inside it. The baffle 206b is fixed to one side of the top of the receiving plate 205. The connecting rod 206c slides in the installation groove V. The pressing ring 206d slides on the first heat exchange pipe 104. The bottom end of the connecting rod 206c is fixed to the pressing ring 206d. The sealing ring 206e is located on the top of the pressing ring 206d. The mounting ring 206f is fixed on the first heat exchange pipe 104 and is located above the sealing ring 206e.

[0043] The number of the convex plates 206a corresponds to that of the receiving plates 205. During installation, the convex plates 206a are first moved above the receiving plates 205 until they contact the baffles 206b, and then they move downward due to the gravity of the first heat exchange pipe 104 itself, so that the convex plates 206a are located on the tops of the receiving plates 205, and thus the first heat exchange pipe 104 can be fixed by the receiving plates 205 and the convex plates 206a.

[0044] The connecting rod 206c is L-shaped. In the initial state, the sealing ring 206e is located on the top of the pressing ring 206d and there is a certain space between it and the mounting ring 206f. When the convex plate 206a is located on the top of the receiving plate 205, the connecting rod 206c moves upward in the installation groove V and drives the pressing ring 206d and the sealing ring 206e to move upward, causing the sealing ring 206e to be squeezed between the sealing ring 206e and the mounting ring 206f. At this time, the sealing ring 206e deforms and has a good sealing effect.

[0045] The seal 206 further includes a push plate 206g, a guide rod 206h, and a second spring 206i. The push plate 206g is fixed to the top of the receiving plate 205. The guide rod 206h is fixed in the installation groove V. The connecting rod 206c slides on the guide rod 206h. The two ends of the second spring 206i are respectively fixed to the inner wall of the installation groove V and the connecting rod 206c.

[0046] The push plate 206g is inserted into the installation groove V. By pushing the push plate 206g, the connecting rod 206c is moved. Since the gravity of the convex plate 206a and the first heat exchange tube 104 acts downward, the push plate 206g can always apply a large thrust to the connecting rod 206c, making the sealing effect of the sealing ring 206e better. At the same time, due to the limiting effect of the push plate 206g, the first heat exchange tube 104 cannot rotate during use, thereby making its installation more stable.

[0047] The guide rod 206h limits the connecting rod 206c to make its up and down movement more stable. The second spring 206i applies a downward pulling force to the connecting rod 206c. When the first heat exchange tube 104 is pushed upward, the second spring 206i drives the connecting rod 206c to reset, so that the sealing ring 206e resets, facilitating the removal of the first heat exchange tube 104.

[0048] The pre-tightening member 208 includes a hook plate 208a, a movable frame 208b, a pressing block 208c, an extension rod 208d, and a cross bar 208e. The hook plate 208a is fixed to the outside of the guide plate 207. Fixed slots Y are provided on both sides of the installation pipe 105. The movable frame 208b slides in the fixed slots Y. The pressing block 208c is fixed to the inner wall of the movable frame 208b and cooperates with the hook plate 208a. The extension rod 208d is fixed to the bottom of the movable frame 208b, and the cross bar 208e is fixed between two adjacent extension rods 208d.

[0049] The hook plate 208a is L-shaped. When installing the second heat exchange tube 106, first install the second heat exchange tube 106 correspondingly in the installation pipe 105. At this time, the hook plate 208a will move into the movable frame 208b. Then, when the first heat exchange tube 104 drives the movable tube 201 to move downward, the extension rod 208d and the movable frame 208b are driven to move downward by the movable tube 201. At this time, the hook plate 208a and the second heat exchange tube 106 are pressed towards the inside of the installation pipe 105 by the pressing block 208c. And a sealing gasket is fixed at the end of the installation pipe 105. When the second heat exchange tube 106 moves towards the inside of the installation pipe 105, its end can be in closer extrusion contact with the sealing gasket, thereby improving its sealing effect.

[0050] A set of extension rods 208d are provided on both sides of each installation pipe 105, and two adjacent extension rods 208d are fixedly connected by a cross bar 208e, improving the convenience of its disassembly and assembly.

[0051] The pre-tightening member 208 further includes a fixed rod 208f, a fixed block 208g, and a third spring 208h. The fixed rod 208f is fixed to the top of the movable tube 201, and its top extends above the cross bar 208e. The fixed block 208g is fixed to the top of the fixed rod 208f, and the two ends of the third spring 208h are respectively fixed to the fixed block 208g and the cross bar 208e.

[0052] The fixed rod 208f slides in the middle of the cross bar 208e. When the movable tube 201 moves up and down, it can drive the fixed rod 208f to move up and down, thereby driving the movable frame 208b to move up and down, squeezing the hook plate 208a. The third spring 208h applies a restoring force to the cross bar 208e and the extension rod 208d, improving the convenience of its reset. When it is necessary to remove the second heat exchange tube 106, the movable tube 201 moves up and resets, driving the fixed rod 208f to move up. At this time, the third spring 208h drives the extension rod 208d and the movable frame 208b to move up, so that they are separated from the hook plate 208a, and the removal of the second heat exchange tube 106 can be completed.

[0053] The installation part 209 includes an installation block 209a, a plug rod 209b, a fixing plate 209c and a trigger block 209d. The installation block 209a is fixed to the outside of the guide plate 207. An installation hole N communicating with it is opened at the top of the fixed groove Y. The plug rod 209b slides in the installation hole N. The fixing plate 209c is fixed to the top end of the plug rod 209b. The trigger block 209d is fixed to the bottom of the fixing plate 209c and is located in the fixed groove Y.

[0054] The installation block 209a is rectangular. When the movable frame 208b moves downward, the movable frame 208b is separated from the trigger block 209d, and the plug rod 209b can be correspondingly inserted into the insertion hole opened at the top of the installation block 209a, thereby fixing the position of the second heat exchange tube 106 and preventing it from detaching from the installation tube 105.

[0055] The installation part 209 further includes a connection block 209e and a fourth spring 209f. The connection block 209e is fixed in the installation hole N. The two ends of the fourth spring 209f are respectively fixed to the connection block 209e and the fixing plate 209c.

[0056] The connection block 209e is fixed by means such as screws, which is convenient for the disassembly and assembly of the fixing plate 209c and the plug rod 209b. This part is not shown in the figure. The fourth spring 209f applies a downward thrust to the fixing plate 209c, making the plug rod 209b more firmly inserted into the insertion hole at the top of the installation block 209a.

[0057] Embodiment 3

[0058] Refer to Figures 1 to 10 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0059] Specifically, the following construction steps are further included:

[0060] Place the adapter box 102 at the position of the angle iron of the transmission tower bracket 101, and install the second heat exchange tubes 106 on both sides on the adapter box 102, and pre-tighten and fix their positions through the pre-tightening parts 208 for subsequent operations;

[0061] Then install the first heat exchange tube 104 correspondingly. At the same time, fix the adapter box 102 and the second heat exchange tubes 106 through the installation assembly 200. At this time, first move the convex plate 206a above the receiving plate 205, rotate the first heat exchange tube 104 so that the convex plate 206a contacts the baffle 206b, and then move downward by the gravity of the first heat exchange tube 104 itself, so that the convex plate 206a is located on the top of the receiving plate 205. In this way, the first heat exchange tube 104 can be fixed by the receiving plate 205 and the convex plate 206a. At this time, push the connecting rod 206c to move through the push plate 206g. The connecting rod 206c moves upward in the installation groove V and drives the extrusion ring 206d and the sealing ring 206e to move upward, so that extrusion occurs between the sealing ring 206e and the installation ring 206f. At this time, the sealing ring 206e deforms and has a good sealing effect;

[0062] At the same time, the convex block 204 rotates correspondingly into the track P. During the downward movement of the first heat exchange tube 104, it drives the movable tube 201 to move downward. By driving the movable tube 201, the first rotating plate 202a is driven to move. Thus, when the first rotating plate 202a approaches or moves away from the second rotating plate 202b, the support plate 202c can be driven to move outward. The adapter box 102 is fastened through the frictional force and supporting force between the support plate 202c and the inner wall of the installation hole S. And because the downward movement of the movable tube 201 is pulled by the convex block 204 and the self-weight of the first heat exchange tube 104, the installation is more stable, and there is no need for the staff to carry too many installation devices, and the safety is higher;

[0063] While the movable tube 201 moves downward, it drives the extension rod 208d and the movable frame 208b to move downward. At this time, the hook plate 208a and the second heat exchange tube 106 are pressed inward into the installation tube 105 through the extrusion block 208c. And a sealing gasket is fixed at the end of the installation tube 105. When the second heat exchange tube 106 moves inward into the installation tube 105, its end can be more closely pressed against the sealing gasket, thereby improving its sealing effect. When the movable frame 208b separates from the trigger block 209d, the insertion rod 209b can be correspondingly inserted into the insertion hole opened at the top of the installation block 209a, so as to fix the position of the second heat exchange tube 106 and prevent it from detaching from the installation tube 105;

[0064] Connect the second heat exchange tube 106 to the ground source heat pump and supply hot water to the first heat exchange tube 104. Through the setting of the water circulation, heat exchange is carried out on the surface of the transmission tower bracket 101, so as to melt the snow and ice, and improve the safety of the transmission tower.
