Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, and in particular to a fan-shaped protective netting that is easy to assemble. Background Technology

[0002] When promoting rural domestic sewage treatment, considering the unique geographical environment of some densely networked waterways in southern China, traditional drainage pipe laying methods could easily damage river ecosystems during construction and affect the normal operation of pipelines due to factors such as water level fluctuations during the flood season. Therefore, these areas have innovatively elevated drainage pipe networks above the water surface. By constructing a stable bridge-pipe system, using micro-steel pipe piles as foundations, and connecting them with angle steel supports, the pipe network is stably suspended above the water. This measure not only reduces disturbance to the river channel and protects the habitat of aquatic life, but also prevents the pipes from aging and being damaged by long-term immersion in river water.

[0003] After the pipeline is installed, in order to prevent people from climbing onto the pipeline and causing safety accidents, a protective net needs to be installed on the side of the steel pipe near the riverbank. The bottom of the protective net is fixed to the angle steel bracket. Existing protective nets are generally connected to the angle steel bracket with bolts, which is time-consuming and inconvenient for quick assembly. Therefore, we disclose a fan-shaped protective net that is easy to assemble to meet people's needs. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows:

[0023] A fan-shaped protective net that is easy to assemble includes a fan-shaped frame 2. Multiple longitudinal grid strips 3 and multiple transverse grid strips 1 are fixedly installed on the inner wall of the fan-shaped frame 2 in an alternating manner. A connecting block 5 is fixedly installed at the bottom of the fan-shaped frame 2. Two rectangular holes 6 are opened on the vertical side of the connecting block 5. Rectangular posts 12 are slidably installed in the two rectangular holes 6. Angle steel brackets 4 are pre-welded and fixed to the two rectangular posts 12. A stop hole 8 is opened on the inner wall of the two rectangular holes 6 that are far apart from each other. A clamping rod 11 is fixedly installed on the side of the two rectangular posts 12 that are far apart from each other. The two clamping rods 11 pass through the two stop holes 8 respectively. A U-shaped plate 10 is installed at the bottom of the connecting block 5 through an elastic mechanism. A clamping hole 9 is opened on the inner wall of both sides of the U-shaped plate 10. The ends of the two clamping rods 11 that are far apart from each other pass through the two clamping holes 9 respectively. Two arc-shaped grooves 7 are opened on the side and top of the U-shaped plate 10. The two arc-shaped grooves 7 correspond to the positions of the two clamping rods 11 respectively.

[0024] With the above structure: during installation, the moving connecting block 5 and the two locking rods 11 press against the two arc-shaped grooves 7, causing the U-shaped plate 10 to move downward. The elastic mechanism deforms, and when the two locking holes 9 correspond to the positions of the two locking rods 11, the U-shaped plate 10 moves upward under the action of the elastic mechanism, so that the two locking rods 11 enter the two locking holes 9 respectively, completing the rapid positioning.

[0025] like Figure 3 and Figure 4 As shown, the elastic mechanism includes a cavity 19 formed on the connecting block 5, a reset plate 17 is provided in the cavity 19, two reset rods 15 are fixedly installed at the bottom of the reset plate 17, the bottom ends of the two reset rods 15 penetrate the bottom inner wall of the cavity 19 and are fixedly installed on the top of the U-shaped plate 10, and a reset spring 20 is sleeved on each of the two reset rods 15, the top ends of the two reset springs 20 are fixedly installed on the bottom of the reset plate 17, and the bottom ends of the two reset springs 20 are fixedly installed on the bottom inner wall of the cavity 19; the elastic mechanism also includes two pull holes 14 formed on the vertical inner wall of the cavity 19, U-shaped pull rods 13 are slidably installed in the two pull holes 14, both ends of the U-shaped pull rods 13 extend into the cavity 19 and are rotatably installed with connecting rods 18, and the bottom ends of the two connecting rods 18 are rotatably installed on the top of the reset plate 17. When disassembly is required, simply pull the U-shaped lever 13. The movement of the U-shaped lever 13 will cause the two connecting rods 18 to move. The movement of the two connecting rods 18 will cause the reset plate 17 to move downward. The movement of the reset plate 17 will cause the two reset rods 15 and the U-shaped plate 10 to move downward. When the two locking holes 9 on the U-shaped plate 10 separate from the two locking rods 11, the connecting block 5 can continue to move, thereby separating the protective net from the angle steel bracket 4 and completing the disassembly. Disassembly can be completed by simply pulling in one direction.

[0026] like Figure 4As shown, the connecting rod 18 is inclined. The advantage of this design is that it facilitates the downward movement of the reset plate 17.

[0027] like Figure 4 As shown, the distance between the top end of the connecting rod 18 and the cavity 19 away from the inner wall of the U-shaped tie rod 13 is less than the distance between the bottom end of the connecting rod 18 and the cavity 19 away from the inner wall of the U-shaped tie rod 13. The advantage of this arrangement is that when the U-shaped tie rod 13 is pulled, the reset plate 17 will move downward.

[0028] like Figure 4 As shown, two reset holes 16 are formed on the bottom inner wall of the cavity 19, and the bottom ends of the two reset rods 15 pass through the two reset holes 16 respectively. The reset holes 16 are provided to limit the position of the reset rods 15.

[0029] like Figure 4 and Figure 3 As shown, the distance between the bottom of the reset plate 17 and the top inner wall of the cavity 19 is greater than the distance between the bottom of the latch 11 and the top of the U-shaped plate 10. The advantage of this arrangement is that the downward movement of the reset plate 17 will cause the latch 11 to move out of the latch hole 9.

[0030] Working principle:

[0031] During installation, the angle steel bracket 4 is pre-welded and fixed to the two rectangular columns 12. The movable connecting block 5 allows the two rectangular columns 12 to enter the two rectangular holes 6 respectively, and the two locking rods 11 to enter the two blocking holes 8 respectively. When the two locking rods 11 contact the two arc grooves 7, the two locking rods 11 squeeze the two arc grooves 7, thereby causing the U-shaped plate 10 to move downward. The movement of the U-shaped plate 10 drives the two reset rods 15 and the reset plate 17 to move downward. The two reset springs 20 deform. When the two locking holes 9 correspond to the positions of the two locking rods 11 respectively, the U-shaped plate 10 moves upward under the action of the two reset springs 20, thereby allowing the two locking rods 11 to enter the two locking holes 9 respectively, completing the limit.

[0032] When disassembly is required, simply pull the U-shaped lever 13. The movement of the U-shaped lever 13 will cause the two connecting rods 18 to move. The movement of the two connecting rods 18 will cause the reset plate 17 to move downward. The movement of the reset plate 17 will cause the two reset rods 15 and the U-shaped plate 10 to move downward. When the two locking holes 9 on the U-shaped plate 10 separate from the two locking rods 11, the connecting block 5 can continue to move, thereby separating the protective net from the angle steel bracket 4 and completing the disassembly. Disassembly can be completed by simply pulling in one direction.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
