Description

Technical Field

[0001] This utility model belongs to the field of water conservancy construction, and more specifically, it relates to an underground pipeline protection structure that is easy to assemble. Background Technology

[0002] Water conservancy pipelines refer to pipeline systems used in water conservancy projects to transport water resources. These pipelines are typically buried underground and used in water conservancy projects such as farmland irrigation and urban water supply and drainage to ensure the effective transmission and distribution of water resources underground. Currently, when the concrete conveying water pipelines in water conservancy construction are laid and connected, the sealing concrete at the connection points between multiple sets of concrete conveying water pipelines has not yet fully solidified. To prevent cracking of the concrete at the connection points due to collisions with external objects, protective frames are usually erected outside the concrete conveying water pipelines for shielding and protection. However, the installation of protective frames requires a large number of bolts and rivets to assemble and install the side plates and crossbeams. As can be seen, the assembly and installation of traditional water conservancy pipeline protective frames is cumbersome and inconvenient. In addition, the rigid and fixed size and structure of the frames prevent the protective frames from being adjusted and installed according to the size of the concrete pipelines, reducing the applicability of the protective frames for shielding and protecting concrete pipelines.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] like Figures 1-10 As shown, this utility model provides an easily assembled underground pipeline protection structure, including a concrete hydraulic pipeline 1; vertical protection devices 2 are placed on the left and right sides of the concrete hydraulic pipeline 1; it also includes a horizontal protection device 3; the horizontal protection device 3 includes a crossbeam frame 301, an extended protection plate 302, a driving bevel gear 303, a protection plate extension knob 304, a bidirectional threaded rod 305, a driven bevel gear 306, a guide rod 307, and a transmission rod 308; the top of the transmission rod 308 is welded with the protection plate extension knob 304, the outer side of the transmission rod 308 is rotatably connected to the crossbeam frame 301, the left and right sides of the crossbeam frame 301 are both welded with the guide rod 307, the outer side of the guide rod 307 is slidably connected to the extended protection plate 302, the bottom end of the transmission rod 308 is welded with the driving bevel gear 303, the outer side of the driving bevel gear 303 is meshed with the driven bevel gear 306, and the driven bevel gear 306 is welded to the outer side of the bidirectional threaded rod 305.

[0029] In this embodiment, the vertical protective device 2 includes a side protective plate 201, a lifting mounting frame 202, a lifting knob 203, a threaded rotating rod 204, a guide post 205, a pin 206, a locking tongue plate 207, a baffle plate 208, a push spring 209, and a support guide rod 210. The top of the threaded rotating rod 204 is welded with the lifting knob 203, and the outer side of the threaded rotating rod 204 is rotatably connected to the side protective plate 201. The lower side of the side protective plate 201 is welded with the pin 206. The top and bottom of the guide post 205 are both welded with the side protective plate 201, and the outer side of the guide post 205 is slidably connected to the lifting mounting frame 202. The upper side of the lifting mounting frame 202 has two sets of rectangular through slots, and the rear side of the lifting mounting frame 202 has three sets of protrusions. A threaded through hole is provided on the protrusion at the center of the rear side of the lifting mounting frame 202. The threaded rotating rod 204 is threadedly engaged with the protrusion threaded through hole of the lifting mounting frame 202 on its outer side. The rear side of the lifting mounting frame 202 has two sets of vertically penetrating through holes on the protrusions near the left and right sides. The guide post 205 is inserted into the through hole structure of the lifting mounting frame 202. During the rotation of the threaded rotating rod 204, the threaded rotating rod 204 drives the lifting mounting frame 202 to move vertically and directionally along the guide post 205 through the thread on its outer side. This allows the lifting mounting frame 202 to adjust the installation height of the horizontal protection device 3 according to the height of the concrete hydraulic pipeline 1. A support guide rod 210 is welded to the front side of the lifting mounting frame 202. A baffle 208 is welded to the front end of the support guide rod 210. A locking tongue plate 207 is slidably connected to the outer side of the support guide rod 210. A push spring 209 is welded to the rear side of the locking tongue plate 207.

[0030] In this embodiment, there are two sets of extended protective plates 302, which are symmetrically distributed on the left and right sides. Each set of extended protective plates 302 has a threaded deep hole at its center. There are two sets of circular deep holes on both the front and rear sides of the threaded deep hole of the extended protective plate 302. The guide rod 307 is inserted into the circular deep hole of the extended protective plate 302. The positive thread end of the outer side of the bidirectional threaded rod 305 is engaged with the threaded deep hole of the left extended protective plate 302, and the negative thread end of the outer side of the bidirectional threaded rod 305 is engaged with the threaded deep hole of the right extended protective plate 302. During the rotation of the bidirectional threaded rod 305, the bidirectional threaded rod 305 drives the two sets of extended protective plates 302 to move in opposite directions along the guide rod 307, so that the left and right sides of the crossbeam frame 301 of the two sets of extended protective plates 302 can be adjusted to increase or decrease the horizontal covering surface of the extended protective plates 302 according to the width of the concrete hydraulic pipeline 1.

[0031] In this embodiment, there are two sets of locking tongue plates 207. Each set of locking tongue plates 207 is an inverted L-shaped structure. A through hole is provided on the front side of the locking tongue plate 207 near the bottom. The support guide rod 210 is inserted into the through hole of the locking tongue plate 207. The locking tongue plate 207 is inserted into the rectangular through slot of the lifting mounting frame 202. The left and right sides of the locking tongue plate 207 are both attached to the left and right slot walls of the rectangular through slot of the lifting mounting frame 202. The locking tongue plate 207 moves horizontally back and forth along the rectangular through slot of the lifting mounting frame 202 and the support guide rod 210. This ensures that the locking tongue plate 207 is stably inserted into the through groove of the extension protective plate 302. The top of the L-shaped structure of the locking tongue plate 207 has a beveled structure. During the process of the extension protective plate 302 being pressed down on the upper side of the lifting mounting frame 202, the bottom end of the rectangular through groove of the extension protective plate 302 pushes against the beveled structure of the locking tongue plate 207, so that the locking tongue plate 207 overcomes the elastic force of the push spring 209 and automatically avoids the bottom end of the rectangular through groove of the extension protective plate 302, ensuring that the locking tongue plate 207 is quickly inserted into the rectangular through groove of the extension protective plate 302.

[0032] In this embodiment, the left end of the side protection plate 201 is provided with a trapezoidal slot, and the right end of the side protection plate 201 is provided with a trapezoidal protrusion. The trapezoidal protrusion of one set of side protection plates 201 is embedded in the trapezoidal slot of another set of side protection plates 201, so that the two sets of side protection plates 201 are connected by interlocking left and right ends, which replaces the connection and fixing structure of the protection plates using rivets, making the installation of the side protection plate 201 more convenient.

[0033] In this embodiment, there are two sets of push springs 209, which are symmetrically distributed on the left and right. Each set of push springs 209 has a locking tongue plate 207 welded to its front end and a lifting mounting bracket 202 welded to its rear end. When the locking tongue plate 207 is fully inserted into the rectangular through slot of the extension protective plate 302, the push spring 209 drives the locking tongue plate 207 to move forward along the rectangular through slot of the lifting mounting bracket 202 and the support guide rod 210 through its own elastic force. This causes the edge of the upper slot of the extension protective plate 302 to penetrate into the L-shaped bending part of the locking tongue plate 207. The L-shaped structure of the locking tongue plate 207 locks the extension protective plate 302 at the upper limit, thus completing the insertion, locking and installation of the vertical protective device 2 of the extension protective plate 302.

[0034] The specific usage and function of this embodiment are as follows:

[0035] When assembling the protective plate frame for the water conservancy pipeline, the first step is to insert the pins 206 welded to the lower side of the two sets of side protective plates 201 into the soil. At this time, the side protective plates 201 stand vertically on the left and right sides of the concrete water conservancy pipeline 1. Then, manually rotate the lifting knob 203, which drives the threaded rod 204 to rotate. The threaded rod 204 then drives the lifting mounting bracket 202, which is engaged with the outer side, to move up or down along the guide post 205 according to the height of the concrete water conservancy pipeline 1. Finally, manually rotate the protective plate extension knob 304 to extend the protective plate. The rotary knob 304 drives the active bevel gear 303, which is welded to the bottom of the transmission rod 308, to rotate. The active bevel gear 303 then drives the driven bevel gear 306, which is meshed with its outer side. The driven bevel gear 306 then drives the bidirectional threaded rod 305 to rotate. Since the forward and reverse threaded ends of the outer side of the bidirectional threaded rod 305 are respectively meshed with the deep threaded holes of the two sets of extended protective plates 302, the bidirectional threaded rod 305 drives the two sets of extended protective plates 302 to move left and right in opposite directions according to the width of the concrete hydraulic pipeline 1, until the rectangular through groove on the upper side of the extended protective plate 302 is reached. With the rectangular slot of the lifting mounting bracket 202 aligned vertically, the extended protective plate 302 is pressed downwards onto the upper side of the lifting mounting bracket 202. At this time, the bottom edge of the rectangular slot of the extended protective plate 302 presses against the inclined structure of the locking tongue plate 207, causing the locking tongue plate 207 to automatically avoid the bottom edge of the rectangular slot of the extended protective plate 302. When the lower side of the extended protective plate 302 is in contact with the upper side of the lifting mounting bracket 202, the locking tongue plate 207 is completely inserted into the inner side of the rectangular slot of the extended protective plate 302. At this time, the push spring 209, through its own elasticity... The force of the action drives the locking tongue plate 207 to move horizontally along the support guide rod 210. The L-shaped bending part of the locking tongue plate 207 fits against the edge of the upper groove of the rectangular through groove of the extended protective plate 302. The L-shaped structure of the locking tongue plate 207 locks the upper limit of the extended protective plate 302, thereby completing the insertion and locking assembly of two sets of vertical protective devices 2 and one set of horizontal protective devices 3. Then, the trapezoidal protrusions of the two sets of side protective plates 201 are inserted into the trapezoidal slots of the other two sets of side protective plates 201, thereby completing the insertion and splicing of multiple sets of vertical protective devices 2.

[0036] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired beneficial effect can be implemented. The concrete hydraulic pipes 1 used above are all common commercially available components; upon purchase and use, simply follow the instruction manual provided with the purchase, and therefore will not be elaborated upon further.
