Technical Field

[0001] The utility model relates to the technical field of photothermal technology, and more specifically, to a heat collecting tube support structure of a trough type photothermal collector. Background Art

[0002] Solar thermal power generation technology is mainly divided into three technical routes: trough type, tower type and dish type. Among them, trough type thermal power generation technology is the most mature. Most large-scale commercial power stations adopt trough type thermal power generation technology. For trough type thermal power generation equipment, its core equipment is trough type solar collector. The basic support of trough type solar collector is trough type solar collector device. The existing trough type solar collector device includes a support shaft. Reflectors are fixedly arranged on both sides of the top of the support shaft through a connecting frame. A heat collecting tube support device is fixedly arranged just above the support shaft. A gap is arranged between the reflectors on both sides for the heat collecting tube support device to pass through. In the above structure, due to the limited gap between the reflectors, the connection structure of the heat collecting tube support device and the support shaft is relatively weak. In order to ensure the normal reflection efficiency of the reflector, it is impossible to increase the gap simply to increase the connection strength of the heat collecting tube support device. A reasonable structure is urgently needed.

This structure of pressing to unlock and rotate, and popping up to lock and not rotate is a conventional design in the prior art. The specific structure is the same as that in the prior art and will not be described in detail here.

[0027] The support assembly can use a straight rod structure, which mainly plays a supporting role. The bottom of the support assembly is provided with a clamping hole 5, which is mainly used to fix the support assembly on other devices that need to be fixed.

[0028] The fixer also includes a fixing hole and a fixing bolt 6. The fixing hole is arranged on the side wall of the clamping hole, and the fixing bolt is screwed into the fixing hole.

[0029] Example 2

[0030] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below:

[0031] like Figure 1As shown, as a preferred embodiment; the bracket assembly 2 is divided into two parts, the upper part of the bracket assembly 2 is the tenon end 11, and the lower part of the bracket assembly 2 is the mortise end 12. The tenon end is provided with a protrusion, and the mortise end is provided with a groove. The protrusion of the tenon end is inserted into the groove of the mortise end. Further, the upper and lower parts of the bracket assembly 2 can be combined, and this mortise and tenon structure is more stable, which can prevent the bracket assembly 2 from loosening.

[0032] Furthermore, in order to enhance the firmness, the corresponding positions of the tenon and the mortise are provided with limiting holes penetrating the tenon and the mortise, and the limiting bolts are inserted into the limiting holes to fix the tenon and the mortise, and the clamping hole is arranged at the bottom of the mortise. The placement groove is arranged at the top of the tenon.

[0033] Among them: when using the device, the relevant personnel insert the tenon end 11 into the mortise end 12, align the limiting hole of the tenon end 11 with the limiting hole 3 of the mortise end 12, adjust the height of the bracket assembly 2 by aligning different limiting holes 3, and then insert the limiting bolt 4 into the corresponding limiting hole 3, and then install the device on the trough-type solar thermal collector bracket assembly 2, and adjust the handle 14 to install the tenon above the bracket assembly. When the position of the collector tube needs to be adjusted, the relevant personnel can press the adjusting handle 14 inward and rotate the adjusting handle 14 at the same time. The adjusting handle 14 drives the swing arm 16 to rotate and thus drives the device body 1 to rotate. When the relevant personnel let go, the spring 18 pushes the adjusting handle 14 outward, thereby fixing the position of the device body 1, and the placement slot 17 can limit the movement of the spring 18. Tighten the bolt 6 to fix the bracket assembly at the position where it needs to be installed.

[0034] like Figure 4 As shown, as a preferred embodiment; the hollow tube cavity 1 is provided with a heat preservation layer 10. Further, the heat preservation layer 10 can isolate the hollow tube cavity 1 from the heat collecting tube. When the heat collecting tube is working, the temperature will become high, and the high temperature will reduce the service life of the device. Therefore, the heat preservation layer 10 can prevent the hollow tube cavity 1 from being affected by the high temperature. When the heat collecting tube is working, the volume will be affected by the temperature and will be installed and contracted when hot. The pressure sensor 9 is embedded in the abutment plate 13. When the pressure exceeds the set value, the cylinder 7 will drive the abutment plate 13 to move through the abutment rod, and the partition 8 will separate the cylinder 7 from the hollow tube cavity 1, thereby preventing the heat collecting tube from loosening or being too tight.

[0035] like Figure 3 As shown, as a preferred embodiment; the surface of the adjustment handle 14 is provided with vertical lines 19, further, the vertical lines 19 can increase friction, prevent the relevant personnel from having difficulty twisting the adjustment handle 14 when there is sweat in their hands, and thus make twisting the adjustment handle 14 easier.

[0036] like Figure 2As shown, as a preferred embodiment; a limiting nut 15 is provided behind the limiting bolt 4. Further, relevant personnel can tighten the limiting nut 15 to prevent the limiting nut 15 from loosening, thereby causing the bracket assembly 2 to loosen.

[0037] like Figure 1 As shown, as a preferred embodiment; a fixing bolt 6 is provided on the left side of the clamping hole 5. Further, when the device is installed on the structure of the trough-type solar thermal collector mounting bracket assembly 2, relevant personnel tighten the bolt 6 to prevent the supporting structure from loosening and tipping over, thereby damaging the collector and the collector tube.

[0038] like Figure 1 As shown, as a preferred embodiment, the limiting holes 3 are arranged in parallel in five groups, totaling ten. Furthermore, the height of the bracket assembly 2 can be adjusted according to the situation, and the number of the limiting holes 3 is not limited. The number of the limiting holes 3 is controlled by relevant personnel.

[0039] like Figure 1 As shown, as a preferred embodiment; there are two limit bolts 4, or no less than two, and when installing the limit bolts, at least one limit bolt is set in the limit hole on each side, further increasing the stability of the bracket assembly 2 and preventing the bracket assembly 2 from tilting to both sides and damaging the device.

[0040] The working process of the utility model is as follows:

[0041] When the trough type solar thermal collector heat collecting tube support structure is in use, the relevant personnel insert the tenon end 11 into the mortise end 12, align the limiting hole 3 of the tenon end 11 with the limiting hole 3 of the mortise end 12, adjust the height of the bracket assembly 2 by aligning different limiting holes 3, and then insert the limiting bolt 4 into the corresponding limiting hole 3, and then install the device on the trough type solar thermal collector bracket assembly 2, tighten the fixing bolt 6, and install the adjustment handle 14 above the bracket assembly 2. When the position of the heat collecting tube needs to be adjusted, the relevant personnel can press the adjustment handle 14 inward and rotate the adjustment handle 14 at the same time. The adjusting handle 14 drives the swing arm 16 to rotate, thereby driving the hollow tube cavity 1 to rotate. When the relevant personnel let go, the spring 18 pushes the adjusting handle 14 outward, thereby fixing the position of the device body 1. The placement groove 17 can limit the movement of the spring 18. When the heat collecting tube is working, its volume will be affected by the temperature and will be installed hot and contracted cold. A pressure sensor 9 is embedded in the abutment plate 13. When the pressure exceeds the set value, the cylinder 7 will drive the abutment plate 13 to move, and the partition 8 will separate the cylinder 7 from the hollow tube cavity 1, thereby preventing the heat collecting tube from loosening or being too tight. This is the working process and working principle of the device.
