Description

Technical Field

[0001] The utility model relates to the technical field of pressure-proof devices, in particular to a pipeline pressure-proof device for garden sprinkler irrigation. Background Art

[0002] In the daily work of garden irrigation, garden workers usually need to connect water pipes and water valves to spray flowers, plants and trees in the garden through water pipes to ensure the healthy growth of plants and the beauty of the garden. However, in this process, it is often necessary to pass the water pipes through the garden roads in order to cover various areas that need irrigation.

[0003] In actual operation, an issue that cannot be ignored is how to safely pass water pipes across garden roads. Due to the particularity of garden roads, although they are not as busy as urban main roads, they are still the only way for pedestrians, non-motor vehicles and garden maintenance vehicles. This means that when water pipes cross roads, various potential risk factors must be taken into account. Whether it is unintentional trampling by pedestrians or crushing by non-motor vehicles or garden maintenance vehicles, it may cause damage to the water pipes. Once the water pipes are damaged, it will not only lead to the interruption of sprinkler irrigation work and affect the normal growth of plants, but also increase additional maintenance costs and time costs. What is more serious is that if the water pipes are damaged and water overflows, it may also cause further damage to the soil and plants in the garden.

[0005] Although the device in the above document can prevent the support seat from being skewed at its connection when it is crushed by a car, the device in the above document cannot adjust the height and width of the anti-pressure device according to the size of the pipeline, which leads to certain limitations in the use of the device in the above document. Utility Model Content

[0006] The utility model aims to provide a garden sprinkler pipe pressure-proof device to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A pipe pressure-proof device for garden sprinkler irrigation comprises a base plate and a baffle; a slide groove 1 is symmetrically provided at the upper end of the base plate, a slide groove 2 is symmetrically provided on the side of the upper end of the base plate away from the slide groove 1, a placement groove is provided in the middle of the base plate, the inner cavities of the two slide grooves 1 are both slidably connected to a first support assembly, the inner cavities of the two slide grooves 2 are both slidably connected to a second support assembly, the opposite surfaces of the first support assembly and the second support assembly on the same side are fixedly connected to a limiting assembly, the middle parts of the two first support assemblies and the middle parts of the two second support assemblies are rotatably connected to a connecting shaft, the baffle is symmetrically rotatably connected to an inclined plate, and a driving assembly is arranged at the lower part of the baffle, and the driving assembly is used to drive the first support assembly and the second support assembly to move.

[0019] A further improvement of the technical solution of the utility model is that: a slide groove three is symmetrically opened on one side of the lower part of the baffle plate close to the slide groove one, and the inner cavity of the slide groove three on the same side is slidably connected to the outer surface of the T-block three; a slide groove four is symmetrically opened on one side of the lower part of the baffle plate close to the slide groove two, and the inner cavity of the slide groove four on the same side is slidably connected to the outer surface of the T-block one.

[0020] The above technical solution is adopted, in which the slide groove three is slidably connected to the T-block three, and the slide groove four is slidably connected to the T-block one, so that when the T-block three and the T-block one move, the moving trajectory of the T-block three and the T-block one can be limited to prevent the T-block three and the T-block one from getting off the track when moving, and both the T-block three and the T-block one are T-shaped designs, and the T-shaped design provides a larger support area, so that the T-block three and the T-block one can support the baffle more stably and reduce the shaking or displacement caused by external force.

The first support assembly and the second support assembly can be driven to move by operating a driving assembly, so that the height of the baffle can be adjusted according to the size of the water pipe. The first support assembly and the second support assembly are fixedly connected to the limit assembly, so that when the first support assembly and the second support assembly move, a plurality of limit assemblies can be used to limit the position of the water pipe to prevent non-motor vehicles or other external forces from applying force to the baffle, causing the water pipe to deviate from the original position when the baffle shakes or moves, thereby affecting the protection effect of the water pipe. The baffle is rotatably connected to the inclined plate, so that the placement angle of the inclined plate can be adjusted according to different position heights, so that the lower end of the inclined plate can always be kept in contact with the ground, and the inclined plate can be used to provide support to the baffle to enhance the pressure resistance of the baffle. Under the cooperation of the inclined plate and the baffle, the water pipe can be prevented from directly contacting the non-motor vehicle, etc., so that the water pipe can be protected.

[0043] Example 3

[0044] like Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the second supporting assembly 3 includes a main rod 2 31, the middle part of the main rod 2 31 is rotatably connected to the connecting shaft 7, the upper part of the main rod 2 31 is rotatably connected to a T-block 3 32, the lower part of the main rod 2 31 is rotatably connected to a T-block 4 33, and the outer surface of the T-block 4 33 on the same side is slidably connected to the inner cavity of the chute 2 13, and the first supporting assembly 2 includes a main rod 1 21, the main rod 1 21 is rotatably connected to the connecting shaft 7, the upper part of the main rod 1 21 is rotatably connected to a T-block 1 22, the lower part of the main rod 1 21 is rotatably connected to a T-block 23, and the outer surface of the T-block 23 on the same side is slidably connected to the inner cavity of the chute 1 11;

[0046] In this embodiment, since the connecting plate 1 51 is fixedly connected to the T-block 3 32, and the connecting plate 2 55 is fixedly connected to the T-block 1 22, when the connecting plate 1 51 and the connecting plate 2 55 move, they will respectively drive the T-block 3 32 and the T-block 1 22 to move, and then the T-block 1 22 slides in the inner cavity of the slide groove 4 62, and the T-block 3 32 slides in the inner cavity of the slide groove 4 62, so that under the cooperation of the first support assembly 2 and the second support assembly 3, the baffle 6 will be driven to move upward, and since the inclined plate 63 is rotatably connected to the baffle 6, when the baffle 6 moves upward, the inclined plate 6 3 can be adjusted so that the lower end of the inclined plate 63 can be in contact with the ground, and the inclined plate 63 can be used to strengthen the support of the baffle 6. When the T-block 1 22 moves, the main rod 1 21 rotates around the connecting shaft 7, so that the T-block 2 23 can be driven to slide in the inner cavity of the slide groove 1 1 under the action of the main rod 1 21. Similarly, when the T-block 3 32 moves, the T-block 3 32 can be driven to rotate around the connecting shaft 7, and then the T-block 4 33 can be driven to slide in the inner cavity of the slide groove 2 13 under the action of the main rod 2 31, thereby driving a number of limit assemblies 4 to move.

[0047] Example 4

[0048] like Figure 7As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the limit assembly 4 includes a connecting rod 41, a sliding rod 42 is slidably connected to the inner cavity of the connecting rod 41, the end of the sliding rod 42 away from the connecting rod 41 is fixedly connected to a constraint plate 44, the side of the constraint plate 44 close to the connecting rod 41 is fixedly connected to a spring 43, the side of the spring 43 close to the connecting rod 41 is fixedly connected to the connecting rod 41, the constraint plate 44 is made of rubber material, and the side of the constraint plate 44 away from the connecting rod 41 is arc-shaped.

[0049] In this embodiment, after the position height of the baffle 6 is adjusted to an appropriate height according to the size of the water pipe, the water pipe is then placed in the inner cavity of the placement groove 12, and then the operating rod 56 is operated to allow the driving assembly 5 to drive the first support assembly 2 and the second support assembly 3 to move, and then the first support assembly 2 and the second support assembly 3 are used to push the limit assembly 4 to move toward the direction of the water pipe, and then the inner cavity of the constraint plate 44 contacts the surface of the water pipe, so that the constraint plate 44 can be used to constrain the position of the water pipe in the inner cavity of the placement groove 12. When the water pipe is slightly deformed due to temperature changes or water flow pressure, it will push the constraint plate 44 to move toward the connecting rod 41, so that the sliding rod 42 will be displaced in the inner cavity of the connecting rod 41, and then the elastic force of the spring 43 will push the constraint plate 44 to reset, and then the position of the water pipe is constrained, and the connecting rod 41 is slidably connected to the sliding rod 42, so that the constraint plate 44 can constrain water pipes of different sizes.

[0050] The working principle of the garden sprinkler pipe pressure protection device is described in detail below.

[0051] like Figure 1-10 As shown, when the garden is sprinkled, the water pipe needs to be protected to prevent the water pipe from being crushed by non-motor vehicles, etc. First, the device is placed on the road surface, and then the operating rod 56 is operated to rotate, and then the operating rod 56 can be used to drive the gear 2 58 to rotate, so that the gear 2 58 meshes with the adjacent gear 1 53, driving the gear 1 53 to rotate. Since the gear 1 53 is fixedly connected to the bidirectional threaded rod 52, the bidirectional threaded rod 52 can be driven to rotate when the gear 1 53 rotates, and then the bidirectional threaded rod 52 cooperates with the connecting plate 1 51 and the connecting plate 2 55 to drive the connecting plate 1 51 and the connecting plate 2 55 to move toward the direction of the gear 1 53;

[0052] Since the connecting plate 1 51 is fixedly connected to the T-block 3 32, and the connecting plate 2 55 is fixedly connected to the T-block 1 22, when the connecting plate 1 51 and the connecting plate 2 55 move, they will respectively drive the T-block 3 32 and the T-block 1 22 to move, and then the T-block 1 22 slides in the inner cavity of the slide groove 4 62, and the T-block 3 32 slides in the inner cavity of the slide groove 4 62, so that under the cooperation of the first support assembly 2 and the second support assembly 3, the baffle 6 will be driven to move upward, and since the inclined plate 63 is rotatably connected to the baffle 6, when the baffle 6 moves upward, the inclined plate 63 can be placed By adjusting the positioning angle, the lower end of the inclined plate 63 can be fitted with the ground, and the inclined plate 63 can be used to strengthen the support of the baffle 6. When the T-block 1 22 moves, the main rod 1 21 rotates around the connecting shaft 7, so that the T-block 2 23 is driven to slide in the inner cavity of the slide groove 1 1 under the action of the main rod 1 21. Similarly, when the T-block 3 32 moves, the T-block 3 32 is driven to rotate around the connecting shaft 7, and then the T-block 4 33 is driven to slide in the inner cavity of the slide groove 2 13 under the action of the main rod 2 31, thereby driving a number of limit assemblies 4 to move;

[0053] After the baffle 6 is adjusted to a suitable height according to the size of the water pipe, the water pipe is then placed in the inner cavity of the placement groove 12, and then the operating rod 56 is operated to allow the driving assembly 5 to drive the first support assembly 2 and the second support assembly 3 to move, and then the first support assembly 2 and the second support assembly 3 are used to push the limit assembly 4 to move toward the direction of the water pipe, and then the inner cavity of the constraint plate 44 contacts the surface of the water pipe, so that the constraint plate 44 can be used to constrain the position of the water pipe in the inner cavity of the placement groove 12. When the water pipe is slightly deformed due to temperature changes or water flow pressure, it will push the constraint plate 44 to move toward the connecting rod 41, so that the sliding rod 42 will be displaced in the inner cavity of the connecting rod 41, and then the elastic force of the spring 43 will push the constraint plate 44 to reset, and then the position of the water pipe is constrained, and the connecting rod 41 is slidably connected to the sliding rod 42, so that the constraint plate 44 can constrain water pipes of different sizes.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
