Description

Technical Field

[0001] The utility model relates to the technical field of pipeline structures, in particular to a pipeline water hammer protection and shock absorbing device. Background Art

[0002] In the fields of high-rise buildings, urban water supply networks, mine water supply networks, etc., in order to promptly eliminate the water hammer effect caused by the sudden start and stop of water pumps in the pipe network, it is usually necessary to configure the pipe network with a water hammer elimination pipeline structure with a water hammer eliminator as the core component to promptly resolve the water hammer and provide protection for the pipe network.

[0003] According to the application number 202220285089.0, a pipeline water hammer damping device is disclosed. It includes: a water pipe; a buffer pipe connected to the water pipe and used to buffer the water hammer inside the water pipe; a fixed component; a buffer component located inside the buffer pipe and connected to the fixed component to slow down the impact of the water flow; a displacement component located on the fixed component and used to move with the water flow so that the water flow contacts the buffer component; a sealing component; the water pipe is connected to the buffer pipe, and a fixed component is provided inside the buffer pipe to facilitate the support of the buffer component and the displacement component, and the displacement component moves in the direction of the water flow.

[0004] The above scheme has certain limitations in actual use. In the above scheme, the water flow drives the baffle to move, thereby driving the sealing component to move, so that the water flow is connected to the buffer component to buffer the water hammer. However, there is a large amount of space in the middle of the baffle. When the water hammer passes, the water flow in the middle part of the water hammer can pass through the baffle quickly without obstruction. At this time, the water flow in the middle part still has impact force, which can have a greater impact on the pipeline, causing damage to the pipeline. For this reason, we provide a pipeline water hammer prevention and shock absorbing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present embodiment provides a pipeline water hammer prevention and shock absorbing device, which is used to buffer the water hammer formed by the water flow during the drainage process of the pipeline. By setting the cooperation between the buffer mechanism 2 and the blocking mechanism 3, when the water flows through the inside of the connecting pipe 1, the blocking mechanism 3 can divert and block the water hammer formed by the water flow when the water flows through the blocking mechanism 3, thereby reducing the impact force of the water flow. At this time, when the water flow impacts the blocking mechanism 3, it also drives the blocking mechanism 3 to move. At this time, the blocking mechanism 3 is connected to the buffer mechanism 2. At this time, the buffer mechanism 2 can buffer the transmitted impact force of the water flow, thereby improving the buffering effect of the water hammer and reducing the damage of the water hammer to the pipeline.

[0023] See also Figure 1 to Figure 4 A pipeline water hammer protection and shock absorbing device comprises a connecting pipe 1, and a buffer mechanism 2 is arranged inside the connecting pipe 1.

[0024] See also Figure 1 , Figure 3The buffer mechanism 2 includes a fixed ring 201, the outer surface of the fixed ring 201 is fixedly connected to the inner wall of the connecting pipe 1, the outer surface of the fixed ring 201 is fixedly connected with two sets of symmetrical guide rods 202, and one end of the guide rod 202 away from the outer surface of the fixed ring 201 is fixedly connected to the inner wall of the connecting pipe 1, and the outer surfaces of the two sets of guide rods 202 are slidably connected with a moving plate 203. In this embodiment, the guide rods 202 can guide the moving plate 203, so that the moving plate 203 is stable on the inner wall of the connecting pipe 1. Sliding, the outer surfaces of the two sets of guide rods 202 are sleeved with buffer springs 204, and the two ends of the buffer springs 204 are respectively fixedly connected to the outer surface of the fixed ring 201 and the outer surface of the movable plate 203. In this embodiment, the movement of the movable plate 203 can squeeze and pull the buffer springs 204 on both sides, so that the blocking mechanism 3 can effectively buffer the impact force transmitted by the water flow when driving the movable plate 203 to slide on the inner wall of the connecting pipe 1. The outer surfaces of the two movable plates 203 are provided with blocking mechanisms 3.

[0025] See also Figure 1 , Figure 4 The blocking mechanism 3 includes a first diverter frame 301 and a second diverter frame 302. The outer surface of the first diverter frame 301 is fixedly connected to the outer surface of the movable plate 203, and the outer surface of the second diverter frame 302 is fixedly connected to the outer surface of the movable plate 203. In this embodiment, the first diverter frame 301 can divert water hammer, thereby reducing the impact force of the water hammer.

[0026] The inner wall of the first diverter rack 301 is rotatably connected to a rotating shaft 303, and one end of the rotating shaft 303 away from the first diverter rack 301 is rotatably connected to the inner wall of the second diverter rack 302, and the outer surface of the rotating shaft 303 is rotatably connected to a fan blade 304. In this embodiment, there is space between the outer rings on both sides of the second diverter rack 302 and the movable plate 203, so that after the water flow hits the second diverter rack 302, the water flow can always hit the fan blade 304, so that the fan blade 304 can continue to rotate stably.

[0027] The outer surface of the second diverter rack 302 is provided with four circular array water holes 305, wherein the inner walls of two water holes 305 are fixedly connected with the first baffle plate 306. In this embodiment, the second diverter rack 302 and the first baffle plate 306 can divert and block the water flow, thereby reducing the impact of water hammer and increasing the protection of the pipeline.

[0028] One end of the rotating shaft 303 is fixedly connected to a mounting plate 307, and the outer surface of the mounting plate 307 is fixedly connected to two symmetrical second blocking plates 308, and the second blocking plates 308 are adapted to the water through hole 305. In this embodiment, the fan blades 304 are driven by the water flow to cause the mounting plate 307 and the second blocking plates 308 to rotate continuously. When the second blocking plates 308 block the water through hole 305, the first blocking plates 306 can be used to block the middle part of the water hammer, and the second blocking plates 308 can rotate continuously driven by the rotating shaft 303, thereby indirectly blocking the water hammer, thereby maintaining the fluidity of the water flow and blocking the water hammer.

[0029] Both ends of the connecting pipe 1 are fixedly connected with the first flange 4, and the outer surfaces of the two first flanges 4 are provided with slots 5. The right end of the connecting pipe 1 is plugged with the water pipe 6, and the left end of the connecting pipe 1 is plugged with the water outlet pipe 10. The outer surfaces of the water pipe 6 and the water outlet pipe 10 are plugged into the inner walls of the slots 5. In this embodiment, when the connecting pipe 1 is connected with the water pipe 6 and the water outlet pipe 10, the water pipe 6 and the water outlet pipe 10 are inserted into the groove of the slot 5, thereby improving the sealing of the connection after the connecting pipe 1 is connected with the water pipe 6 and the water outlet pipe 10.

[0030] The ends of the water supply pipe 6 and the water outlet pipe 10 that are close to each other are fixedly connected with the second flange 7, the outer surfaces of the two second flanges 7 are inserted with bolts 8, and the outer surfaces of the bolts 8 are inserted into the inner wall of the first flange 4, and the outer surfaces of the bolts 8 are threadedly connected with nuts 9.

[0031] Working principle: When using this embodiment, first, insert the water pipe 6 and the water outlet pipe 10 into the interior of the connecting pipe 1. At this time, the water pipe 6 and the water outlet pipe 10 are inserted into the groove of the slot 5 at the same time. Then, when the connecting pipe 1 is connected with the water pipe 6 and the water outlet pipe 10, the first flange 4 and the second flange 7 are docked. The connecting pipe 1, the water pipe 6 and the water outlet pipe 10 can be fixedly connected by bolts 8 and nuts 9. Then, when the water flows through the connecting pipe 1, the water flow can be diverted under the first diverter frame 301. Then, the water flow drives the fan blade 304 to rotate, thereby driving the mounting plate 307 and the second baffle plate 308 to rotate. At this time, when the water flows through the second diverter frame 3 02, the flow can be diverted again, and blocked under the action of the first blocking plate 306, and while the second blocking plate 308 rotates, the second blocking plate 308 intermittently blocks the water hole 305, thereby allowing the water flow to pass intermittently, thereby reducing the impact force of the water flow, and finally, when the water flow drives the blocking mechanism 3 to move as a whole, the blocking mechanism 3 is connected to the moving plate 203, thereby allowing the moving plate 203 to slide on the inner wall of the connecting pipe 1, and while the two moving plates 203 move, the two sets of buffer springs 204 are squeezed and pulled, and under the action of the buffer springs 204, the water flow impact force transmitted by the blocking mechanism 3 can be buffered, thereby protecting the pipeline.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
