Abstract

The utility model relates to a channel applied to solar energy collectors. The utility model comprises a shell with an interface, a plurality of connecting bolt components which are used for connecting the channel with a frame and arranged into two rows with each two bolts opposite and distributed at the two sides of the interface of the shell. Each two corresponding connecting bolts are provided with a gusset plate between. The collector channel of the utility model, which is fixedly connected with the frame, adopts an interface of a seam form, thereby making the appearance of the collector more beautiful; the utility model is fixed on the frame by bolts and a dead plate because the bolts have a high strength and the dead plate may prevent the shell from being torn by the bolts and the interface of the shell from splitting, thus, the utility model witnesses a quite firm connection between the collector channel and the frame.

Description

The heat collector header that is connected firmly with support

Technical field

The utility model relates to a kind of header that is used for solar thermal collector, especially a kind of heat collector header that is connected firmly with support.

Background technology

Header is the critical piece of solar thermal collector, its structure as shown in Figure 1, comprise that the cross section is rectangular cylindrical case 1, inner bag, is filled in thermal insulator and fixed head between shell 1 and the inner bag, wherein be provided with fillet 10 in the both sides of shell 1, be connected with several connecting bolts 2 between fillet 10 and the fixed head, these connecting bolts 2 are used for header is fixed to support simultaneously.In this kind structure, because fillet 10 and shell are one, thickness has only 0.4mm, thus very insecure by the fixing header of fillet 10, usually because the distortion of fillet 10, tear and damage; Because be provided with fillet 10 on the header, the structure relative complex has been wasted raw material simultaneously.As shown in Figure 2, existing another kind of header structure and header structure difference shown in Figure 1 are that shell is directly the iron plate bending to be formed rectangle, are formed with at interface and overlap, and be fixing with pulling rivet 11 at lap, so just saved fixed head.Though the header of this kind structure has been saved raw material, but because when mounted, directly header is fixed on the support with eight pulling rivets that are distributed in housing interface both sides, because the intensity of pulling rivet is limited, so header is still firm inadequately with being connected of support, also, or break away from support usually because pulling rivet distortion, fracture or header shell are torn etc. header is damaged.In addition, the header outward appearance of two kinds of structures is untidy, not attractive in appearance more than.

The utility model content

(1) technical problem that will solve

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of and is connected firmly and heat collector header attractive in appearance with support.

(2) technical scheme

For achieving the above object, the utility model adopts following technical scheme:

Heat collector header described in the utility model, comprise shell with interface, comprise also that wherein several are connected to connecting bolt on the support with header, these connecting bolts relatively are divided into two row in twos, be distributed in the both sides of enclosure interface, be connected with gusset plate between corresponding two connecting bolts.

Described connecting bolt is by being fixedly connected on the gusset plate.

Preferably, described connecting bolt is fixed on the gusset plate by welding manner.

Preferably, the fixed-site corresponding to the polygonal bolt head of each connecting bolt has a groove that stops that prevents its rotation on the described gusset plate.

Further, describedly stop that the shape of groove is corresponding with the shape of the polygonal bolt head of described connecting bolt.

Further, described connecting bolt has the polygonal bolt head on six limits, and the described groove that stops is a rectangle, and its two relative wall matches with a pair of relative edge of the polygonal bolt head of described connecting bolt.

The interface connected mode of wherein said shell is that seaming connects.

(3) beneficial effect

The advantage and the good effect of heat collector header described in the utility model are: the outward appearance of heat collector header is more attractive in appearance; The mode that the utility model has adopted screw bolt reinforcing to decide plate is fixed on the support, the intensity of bolt is big, fixed head can increase fixing, the bonding strength of shell, and can prevent that enclosure interface from splitting, so heat collector header described in the utility model is very firm with being connected of support.

The specific embodiment

Below in conjunction with accompanying drawing, further describe the specific embodiment of heat collector header described in the utility model, but be not used for limiting protection domain of the present utility model.

As Fig. 3, Fig. 4, shown in Figure 5, heat collector header described in the utility model comprises that the cross section is rectangular cylindrical case 1, inner bag 5, is filled in the thermal insulator 6 between shell 1 and the inner bag 5.

As Fig. 5, Fig. 6, shown in Figure 7, shell 1 both sides in the utility model relatively are distributed with two row connecting bolts 2 in twos, are connected with gusset plate 3 between corresponding two connecting bolts 2, and these connecting bolts 2 are used for header is connected to support.Between gusset plate 3 and the corresponding connecting bolt 2 can be relative movable, but for easy for installation, usually it is arranged to relatively-stationary connected mode.Fixing can the realization between gusset plate 3 and the connecting bolt 2 by the spot welding mode, also can by other electricity or mechanical structures realize, as on gusset plate 3 corresponding to the hex bolts head fixed-site of each connecting bolt 2 have one prevent its rotation stop groove 4, bolt hex bolts head two opposite side and stop that the both sides of groove work in coordination just can play the effect that prevents the connecting bolt rotation.In addition, when connecting bolt 2 is that polygonal bolt heads such as four angle head bolts or anistree bolt are when having the even number limit, match with a pair of relative edge of the polygonal bolt head of connecting bolt 2 as long as stop two relative cell walls of groove 4, can play the effect that prevents that connecting bolt from rotating equally.In addition polygonal bolt head directly is welded on the fixed head and also can obtains same effect.Prevent that connecting bolt from rotating mainly is for convenient, laborsaving when being installed to the utility model on the support.

Heat collector header described in the utility model, the mode that has adopted screw bolt reinforcing to decide plate is fixed on the support, and the intensity of bolt is big, and fixed head can prevent that enclosure interface from splitting and shell is torn, so very firm.

As shown in Figure 5 and Figure 8, the interface connected mode of the shell 1 in the utility model is that seaming connects, and can prevent that like this sheet material burr of making shell 1 from exposing, and not only attractive in appearance, main is the corrosion that can prevent air, rainwater etc., increases the service life.

More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that the utility model is protected.
