[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0045] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.
[0046] According to an embodiment of the present invention, a drainage device is provided for fixed connection between a support structure 1 and a membrane structure 2, comprising: a drainage structure 3 fixed to the support structure 1, the drainage structure 3 having a receiving cavity, and one end of the drainage structure 3 away from the support structure 1 being fixedly connected to the membrane structure 2; and a diverting member 4 disposed in the receiving cavity, the diverting member 4 having a drainage channel, the bottom end of the diverting member 4 being inclined for diverting water in the drainage channel.
[0047] By setting up the drainage component 4 and tilting its bottom end to create a drainage slope, the water in the drainage channel can be completely drained. As a result, the membrane structure 2 can be set as a planar structure, which reduces the use of supporting components, lowers construction costs and difficulty, makes the stress more uniform, and improves structural stability. At the same time, it can reduce the self-weight of the structure, thereby increasing the service life and load-bearing capacity of the structure. It also avoids the risk of water leakage caused by the deposition of silt in the drainage channel and reduces the cost of later maintenance.
[0048] like Figure 1 As shown, in one embodiment, the supporting structure 1 is a purlin bracket, and multiple purlin brackets are spaced apart above the truss structure. A drainage structure 3 is fixed above the purlin brackets. The purlin brackets and the drainage structure 3 are welded together by a weld around the purlin brackets. By fixing the drainage structure 3 above the purlin brackets, the drainage structure 3 can also function as a purlin, thereby saving materials, reducing installation steps, and reducing the structural weight. As an alternative implementation, the supporting structure 1 can also be a truss structure, i.e., the drainage structure 3 is directly fixed above the truss structure. As an alternative implementation, the purlin brackets may have snap-fit grooves, and the drainage structure 3 may be disposed within the snap-fit grooves; alternatively, the purlin brackets and the drainage structure 3 may be fixedly connected by bolts. No further limitations are imposed here.
[0049] In one embodiment, the membrane structure 2 is supported by an arc-shaped steel pipe, and the ends of the membrane structure 2 are inclined.
[0050] like Figure 2 As shown, in one embodiment, the drainage structure 3 has a U-shaped cross-section, including a base plate 301 and two oppositely arranged side plates 302, which together form a receiving cavity. The base plate 301 and the two side plates 302 are 8mm thick, the base plate 301 is 200mm wide, and the side plates 302 are 300mm wide. The ends of the side plates 302 away from the base plate 301 are bent outwards at a 45° angle. The base plate 301 and the side plates 302 are made of steel plates. The width direction of the base plate 301 is... Figure 2 The horizontal direction of the side panel 302, i.e., the width direction of the side panel 302. Figure 2The vertical direction of the membrane structure 3 is as follows. As an alternative implementation, the drainage structure 3 may also include a detachably connected top plate with a square cross-section; this is not a limitation. As an alternative implementation, the thickness of the bottom plate 301 and the side plate 302 may be 7mm or 9mm; this is not a limitation. As an alternative implementation, the width of the bottom plate 301 may be 190mm or 210mm; this is not a limitation. As an alternative implementation, the width of the side plate 302 may be 290mm or 310mm; this is not a limitation. As an alternative implementation, the end of the side plate 302 away from the bottom plate 301 may be bent outwards at 40° or 50°, and the angle of the outward bending of the end of the side plate 302 is adjusted according to the end inclination angle of the membrane structure 2; this is not a limitation. As an alternative implementation, the bottom plate 301 and the side plate 302 may also be made of aluminum or other rigid materials; this is not a limitation.
[0051] In one embodiment, the drainage element 4 is a flexible element. The drainage element 4 has a U-shaped cross-section within the drainage structure 3, with the closed end of the U-shape forming a drainage channel; the flexible element is made of waterproof material. Using a flexible element as the drainage element 4 facilitates adjustment of its tilt angle, and the lightweight nature of the flexible element reduces the overall structural weight. As a possible implementation, the cross-sectional shape of the drainage element 4 within the drainage structure 3 is determined based on the shape of the receiving cavity, and no further limitations are imposed here.
[0052] like Figure 2 As shown, in one embodiment, along the extension length direction of the drainage structure 3, two fixing positions are spaced apart on the inner wall of the drainage structure 3. Along the extension height direction of the drainage structure 3, the distances between the two fixing positions and the bottom end of the drainage structure 3 are different. The draining member 4 is fixedly connected to the drainage structure 3 through the fixing positions. Specifically, two fixing positions are spaced apart on the inner walls of both side plates 302, and the fixing positions on the two side plates 302 are arranged opposite to each other. The fixing position is a groove 5, and the draining member 4 extends into the groove 5 for fixing. The groove 5 is a circular groove with a depth of 4mm. By setting different distances between the two fixing positions and the bottom end of the drainage structure 3, an angle can be formed between the bottom end of the draining member 4 and the bottom end of the drainage structure 3, thereby facilitating drainage. As an alternative implementation, three or four fixing positions can also be spaced apart on the inner wall of the drainage structure 3 along the extension length direction; no further limitations are imposed here. As an alternative implementation, the fixing position can also be a protrusion, and the draining member 4 is supported on the protrusion for fixing.
[0053] In one embodiment, multiple fixing positions are spaced apart along the extension height direction of the drainage structure 3. By spaced apart multiple fixing positions along the extension height direction of the drainage structure 3, the inclination angle between the bottom end of the guide member 4 and the bottom end of the drainage structure 3 can be adjusted, thereby allowing the drainage channel between the multiple drainage structures 3 to present a gradually inclined state without any drainage dead angles. As an alternative implementation, the fixing position can also be a groove, in which the guide member 4 slides to adjust the inclination angle between the bottom end of the guide member 4 and the bottom end of the drainage structure 3.
[0054] like Figure 2 As shown, in one embodiment, the drainage device includes a fixing component 6, with both ends of the fixing component 6 extending into two oppositely arranged grooves 5 for fixing the draining member 4. The fixing component 6 extends from the inside of the drainage channel into the groove 5, thereby fixing the bottom end of the draining member 4 within the groove 5. By using the fixing component 6 to fix the draining member 4 within the groove 5, the position of the draining member 4 can be adjusted according to the tilt angle, and the fixing method is simple and secure. As an alternative implementation, a snap-fit component can also be provided within the groove 5, with the draining member 4 extending into the groove 5 and being snapped in place by the snap-fit component.
[0055] like Figure 2 As shown, in one embodiment, the fixing component 6 includes: a first fixing member 601; and a second fixing member 602, which is telescopically connected to the first fixing member 601 and used to adjust the length of the fixing component 6. Specifically, one end of the first fixing member 601 has a cavity with an internal thread, and one end of the second fixing member 602 has an external thread. The second fixing member 602 extends into the cavity for threaded fixing. By making the fixing component 6 a telescopic structure, it is easy to adjust the length of the fixing component 6 so that both ends of the fixing component 6 can be inserted into two oppositely arranged grooves 5. As an alternative implementation, the fixing component 6 can also be an elastic structure, utilizing elasticity to insert both ends of the elastic structure into two grooves 5 respectively.
[0056] like Figure 2 As shown, to prevent relative movement between the first fixing member 601 and the second fixing member 602, multiple through holes are provided at one end of the first fixing member 601 and one end of the second fixing member 602. After the second fixing member 602 is inserted into the cavity of the first fixing member 601, the first connector 10 is inserted into the through hole for fixation. The first connector 10 is a pin. Alternatively, one end of the first fixing member 601 may have one through hole, and one end of the second fixing member 602 may have multiple through holes; or one end of the first fixing member 601 may have multiple through holes, and one end of the second fixing member 602 may have one through hole. Alternatively, the first connector 10 may be a cylinder or a screw; no further limitations are imposed here.
[0057] like Figure 2 As shown, in one embodiment, the drainage device includes a connector 7, fixedly connected to the end of the drainage structure 3 away from the supporting structure 1, for fixing the membrane structure 2. Specifically, two connectors 7 are spaced apart at the ends of the two side plates 302 away from the bottom plate 301; the connector 7 is a flat plate, welded and fixed to the side plate 302. By providing the connectors 7, the connection with the membrane structure 2 is tighter, and the end of the membrane structure 2 can be guided to the top of the drainage channel, preventing water from flowing in from the gap between the diverter 4 and the drainage structure 3 and being unable to drain away. As an alternative implementation, each side plate 302 may also have three or four connectors 7, without much limitation here.
[0058] like Figure 1 As shown, in one embodiment, the connector 7 has a through hole, and the membrane structure 2 is disposed on one side of the connector 7. A second connector 11 passes through the through hole for fixing the membrane structure 2. The second connector 11 is a bolt; and a washer is provided between the bolt head and the membrane structure 2 to prevent the bolt head from tearing the membrane structure 2. Alternatively, the end of the membrane structure 2 can be tied to the connector 7 with a cable tie, or the end of the membrane structure 2 can be glued to the connector 7, as long as the membrane structure 2 can be fixed to the connector 7. Alternatively, the second connector 11 can also be a rivet or a screw; no further limitations are imposed here.
[0059] like Figure 1 As shown, in one embodiment, the connector 7 is inclined to match the inclination angle of the membrane structure 2. By inclining the connector 7, it can be adapted to the end shape of the membrane structure 2, thereby preventing the end of the drainage structure 3 from tearing or wearing down the membrane structure 2 and shortening its service life. As an alternative implementation, a flexible support member can also be fixed to the end of the drainage structure 3, in which case the connector 7 can be horizontally arranged; no further restrictions are imposed here.
[0060] In one embodiment, the end of the draining member 4 away from the supporting structure 1 is fixedly connected to the connector 7. Specifically, the draining member 4 is located on the other side of the connector 7, and the second plug 11 is used to fix the draining member 4. A washer is provided between the nut and the draining member 4 to prevent the nut from damaging the draining member 4. By fixing the draining member 4 to the connector 7, water can be prevented from flowing in through the gap between the draining member 4 and the drainage structure 3 and thus being unable to drain away. As an alternative implementation, the end of the draining member 4 can be disposed close to the side plate 302, such as by pasting it onto the side plate 302, without being fixedly connected to the connector 7.
[0061] like Figure 1As shown, in one embodiment, a reinforcing member 8 is provided between two oppositely arranged connecting members 7. The reinforcing member 8 is a stiffening plate with a thickness of 5mm. The width direction is... Figure 2 The horizontal direction is shown in the diagram. By providing the reinforcing member 8, the strength of the connecting member 7 can be improved, preventing cracking between the connecting member 7 and the drainage structure 3. As an alternative implementation, the contact area between the connecting member 7 and the side plate 302 can be increased, thus eliminating the need for the reinforcing member 8. As an alternative implementation, the thickness of the reinforcing member 8 can also be 4mm or 6mm; no further restrictions are imposed here.
[0062] According to an embodiment of the present invention, another aspect provides a shielding system, including: a support structure 1; a membrane structure 2, spaced apart from the support structure 1; and the aforementioned drainage device, fixedly connected between the support structure 1 and the membrane structure 2.
[0063] In one embodiment, multiple drainage devices are provided, and the distance between the bottom end of the drain element 4 of each drainage device and the bottom end of the drainage structure 3 is different. By setting the distance between the bottom end of the drain element 4 of each drainage device and the bottom end of the drainage structure 3 to be different, multiple drainage channels can be made to present a gradually inclined state, thereby avoiding the occurrence of drainage dead zones.
[0064] In one embodiment, such as Figure 2 Figure 1 As shown, a flexible element 9 is provided at the end of the drainage structure 3 away from the supporting structure 1. The flexible element 9 is used to support the membrane structure 2. The flexible element 9 is a rubber pad with a cavity, which is inserted into the end of the side plate 302 for fixation. By providing the flexible element 9, the membrane structure 2 can be prevented from being torn, thus preventing danger.
[0065] Furthermore, a rubber pad is also provided in the groove 5 to support the drainage component 4. Specifically, the rubber pad drives the drainage component 4 to be fixed in the groove 5, and the cavity is oriented towards the drainage channel. The end of the fixing component 6 extends into the cavity for fixation. As an alternative implementation, the end of the drainage structure 3 and the groove 5 can be chamfered, in which case the flexible component 9 can be omitted. As an alternative implementation, the flexible component 9 can also be a silicone pad or other structures with cushioning properties; no further restrictions are imposed here.
[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
