Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1, the protective structure of a flowmeter for hydraulic engineering according to an embodiment of the present invention includes two upper horizontal pipes 1 for communicating with two sides of the flowmeter, a vertical pipe 2 is hinged to the other end of the upper horizontal pipe 1, a lower horizontal pipe 3 is hinged to the other end of the vertical pipe 2, the upper horizontal pipe 1 and the lower horizontal pipe 3 have the same hinge direction on the vertical pipe 2 and are both communicated with the vertical pipe 2, the vertical pipe 2 is vertically buried underground during installation, the upper horizontal pipe 1 and the lower horizontal pipe 3 are horizontally buried, so that when two lower horizontal pipes 3 are respectively subjected to two-direction pulling forces, the overall length can be extended through the hinge relation, compared with the original method of directly mounting the flowmeter on a pipeline section, the design can prevent the flowmeter from being pulled rigidly, when the pulling force is too large, only the vertical pipe 2 or the lower horizontal pipe 3 can be damaged, and no obvious damage can be caused to the flowmeter, standpipe 2 or go up violently pipe 1 and violently pipe 3 down the manufacturing cost here compare in the flowmeter extremely low, so played an economic nature, is in under the condition that normally subsides on ground, and it is comparatively even to subside, consequently drags the range can not be too big, so standpipe 2 and violently pipe 3 direct damage's probability is extremely low down, unless meetting the condition of collapsing, nevertheless still can meet unavoidable deformation when normal atress, this can not lead to the fact the influence to discharge expert.

As shown in fig. 1 and 4, in some embodiments, the upper horizontal tube 1 and the lower horizontal tube 3 are both in a bent shape, the upper horizontal tube 1 and the lower horizontal tube 3 are both hinged to the vertical tube 2 through the annular plate 4 fixed to the end of the upper horizontal tube 1, here, the upper horizontal tube 1 is hinged to the vertical tube 2, the end of the vertical tube 2 is sealed, the vertical tube 2 is close to the side wall of the end, and a communication port is formed in the side wall of the end, the annular plate 4 is fixed to the end of the upper horizontal tube 1, namely, the tube opening of the upper horizontal tube 1 is fixed to the inner opening edge of the annular plate 4, the outer circumferential side of the annular plate 4 is rotatably connected to the communication port of the vertical tube 2, so that the hinged relationship between the two is realized, and in order to facilitate the rotating relationship of the rotating connection between the annular plate 4 and the vertical tube 2, the cross section of the vertical tube 2 is set to be rectangular.

As shown in fig. 2-4, in some embodiments, the two ends of the vertical tube 2 can rotate independently, i.e. can rotate around the axial line in the length direction thereof, and the light can only enable the whole body to achieve one horizontal expansion through two identical hinged relations between the upper horizontal tube 1 and the lower horizontal tube 3 on the vertical tube 2, i.e. only can cope with the horizontal pulling force, so that when the two ends of the vertical tube 2 can rotate independently, a vertical hinged relation is added between the upper horizontal tube 1 and the lower horizontal tube 3, so that the whole body has one more function of coping with the force stressed in the horizontal direction.

As shown in fig. 2-4, in some embodiments, the vertical pipe 2 is divided into two sections, the two sections are rotatably connected by a cylinder 5, the two sections are equivalent to two rectangular hollow blocks, two opposite surfaces between the opposite sides of the two sections are respectively provided with a circular opening, two ends of the cylinder 5 are respectively inserted into the two circular openings, the circumferential sides are tightly attached to each other and are not permeable to water, and two end parts of the cylinder 5 are limited, so that the vertical pipe 2 can independently rotate at the upper end and the lower end of the whole vertical pipe.

As shown in fig. 3, in some embodiments, two sections of the standpipe 2 can slide on the cylinder 5, that is, the upper and lower sections of the standpipe 2 can slide on the cylinder 5 along the axial direction of the cylinder 5, so that the standpipe 2 can be extended and retracted in a short distance as a whole, the length of the cylinder 5 is greater than twice the thickness of the shell of the blocks, that is, the distance between the limiting positions of the two ends of the cylinder 5 is large enough, so that the upper and lower blocks can slide on the cylinder 5, so that when the whole standpipe 2 is buried underground, a slidable room is left between the upper and lower sections, so that the standpipe 2 can be extended and retracted when there is extrusion above the ground, and the vertical pulling force or extrusion force can be handled.

As shown in fig. 1, in some embodiments, the hinged ends of the upper horizontal tube 1 and the lower horizontal tube 3 are bifurcated, the connection of the upper horizontal tube 1 and the vertical tube 2 is still used as an example, that is, the end of the upper horizontal tube 1 is equivalent to two symmetrical bending heads, the end of the vertical tube 2 is located between the two bending heads, and the shape of the upper horizontal tube 1 and the vertical tube 2 is like a clamping structure, so that the hinged part is stable and firm, the effect of increasing the strength of the upper horizontal tube 1 is achieved, the hinged parts between the upper horizontal tube 1 and the lower horizontal tube 3 and the vertical tube 2 are provided with sealing cloth, so that all the hinged parts are shielded, the connecting part is prevented from being blocked by silt, and the connecting part cannot rotate.
