DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1 to Figure 5 The utility model provides a water supply and drainage intercepting device, including a pipeline 1, which is connected to other pipelines through a flange (not shown in the figure). The flange is a mature prior art, and its structure and connection method are common knowledge for those skilled in the art, so it is not repeated in the utility model. An intercepting component 2 is provided in the pipeline 1.

[0024] See also Figure 1 to Figure 5The intercepting assembly 2 includes a baffle ring 21 and an intermediate plate 22. The baffle ring 21 is arranged inside the pipe 1 and fixedly connected to the inner wall of the pipe 1. The baffle ring 21 is provided with an intermediate plate 22. Both sides of the intermediate plate 22 are rotatably connected with intercepting plates 23. The intercepting plates 23 are all semicircular plates. When the two intercepting plates 23 are parallel to the intermediate plates 22, the intermediate plates 22, the intercepting plates 23 and the baffle ring 21 can cooperate to form a blocking structure, thereby achieving the interception effect. Torsion springs are provided at the connections between the intercepting plates 23 and the intermediate plates 22. When the torsion springs are in a natural state, the intercepting plates 23 are perpendicular to the intermediate plates 22, so that water can pass normally.

The surface of the first sleeve shaft 25 is provided with two first circulation grooves in opposite directions, and the first sliders 251 are matched with the first circulation grooves one by one. The first sliders 251 are provided with first guide pillars matched with the first circulation grooves. When the first sleeve shaft 25 rotates unidirectionally, it can drive the two first sliders 251 to synchronously reciprocate and reversely move. Push plates 253 are provided on both sides of the first sleeve shaft 25, and connecting rods 252 are rotatably provided between the first sliders 251 and the push plates 253 (that is, one end of the connecting rod 252 is rotatably connected to the push plates 253, and the other end of the connecting rod 252 is rotatably connected to the first sliders 251). When the two first sliders 251 approach each other, they can drive the two push plates 253 to move away synchronously, and the push plates 253 are matched with the intercepting plates 23 one by one, thereby driving the intercepting plates 23 to rotate.

[0025] See also Figure 1 to Figure 5 A second rotating shaft 26 is rotatably provided on the side of the first rotating shaft 24 away from the middle plate 22. Both ends of the second rotating shaft 26 are rotatably connected to the inner wall of the pipeline 1. A rope shaft 273 is rotatably provided in the middle of the second rotating shaft 26. A plurality of connecting ropes 273 are connected and wound on the rope shaft 273. The plurality of connecting ropes 273 are respectively connected to the two intercepting plates 23, and the number of connecting ropes 273 connected to the two intercepting plates 23 is the same. A torsion spring is provided at the connection between the rope shaft 273 and the second rotating shaft 26. When the intercepting plate 23 is perpendicular to the middle plate 22, the torsion spring is in a natural state. At this time, the connecting rope 273 is completely wound around the rope shaft 273. A second sleeve shaft 28 is rotatably provided at both ends of the first rotating shaft 24, a second slider 281 is provided on the second sleeve shaft 28, a second circulation groove is provided on the surface of the second sleeve shaft 28, a second guide column matching the second circulation groove is provided on the second slider 281, a fixed disk 282 is provided on the second slider 281, a plurality of pin holes 283 are provided on the fixed disk 282, end plates 271 are provided at both ends of the rope shaft 27, a latch 272 which can match with the pin hole 283 is provided on the end plate 271, and when the latch 272 matches with the pin hole 283, the rope shaft 27 can be locked.

[0026] See also Figure 1 to Figure 5A belt is provided between the first rotating shaft 24 and the second rotating shaft 26, a positive ratchet is provided on the first sleeve shaft 25, a positive pawl is connected to the first rotating shaft 24 for unidirectional rotation, a reverse ratchet is provided on the second sleeve shaft 28, a reverse pawl is connected to the second rotating shaft 26 for unidirectional rotation, and a torsion spring is provided at the connection between the first rotating shaft 24 and the positive pawl and at the connection between the second rotating shaft 26 and the reverse pawl.

[0027] See also Figure 1 to Figure 5 Preferably, a limit rod passing through the first slider 251 is provided next to the first rotating shaft 24, both ends of the limit rod are connected to the inner wall of the pipeline 1, and a telescopic shaft is connected between the second slider 281 and the inner wall of the pipeline 1. The limit rod and the telescopic shaft can prevent the first slider 251 and the second slider 281 from rotating.

[0028] See also Figure 1 to Figure 5 Preferably, one end of the first rotating shaft 24 or the second rotating shaft 26 passes through the side wall of the pipeline 1 and is connected to the output shaft of the driving member, so that the device can achieve automatic adjustment.

[0029] See also Figure 1 to Figure 5 Preferably, the push plate 253 is provided with a chamfer so that the device can achieve the function of flow regulation.

[0030] See also Figure 1 to Figure 5 Preferably, a sealing ring 211 capable of cooperating with the intercepting plate 23 is provided on one side of the retaining ring 21, so as to improve the intercepting effect.

[0031] During the implementation of the utility model: when it is necessary to intercept, the user starts the driving member, and the driving member drives the first rotating shaft 24 and the second rotating shaft 26 to rotate forward, at this time, the positive ratchet cooperates with the positive pawl, and the reverse ratchet does not cooperate with the reverse pawl (at this time, the latch 272 and the pin hole 283 are in a disengaged state), the first sleeve shaft 25 rotates, and the second sleeve shaft 28 does not rotate. When the first sleeve shaft 25 rotates, the two first sliding blocks 251 approach each other, and under the action of the connecting rod 252, the two push plates 253 push the two intercepting plates 23 to rotate synchronously, and when the intercepting plate 23 cooperates with the baffle ring 21, the intercepting plate 23, the baffle ring 21, the middle plate 22 and the sealing ring 211 cooperate with each other to form a blocking structure, thereby realizing interception.

[0032] When flow regulation is required, the driving member first rotates forward to move the two push plates 253 away from each other. When the intercepting plate 23 cooperates with the chamfer on the push plate 253, the intercepting plate 23 rotates a certain angle and does not completely fit with the retaining ring 21 (in this process, the rope shaft 27 rotates with the movement of the intercepting plate 23, and the connecting rope 273 automatically extends). Then the driving member reverses. At this time, the anti-ratchet and the anti-ratchet cooperate, and the two second sliders 281 both move toward the rope shaft 27. The latch 272 cooperates with the pin hole 283 to lock the rope shaft 27. At this time, the connecting rope 23 cooperates with the push plate 253 to lock the rotation angle of the intercepting plate 23 to prevent it from shaking when impacted by water flow, thereby reducing the risk of damage to the device.

[0033] The utility model provides a water supply and drainage interception device, which has the following beneficial effects:

[0034] 1. By setting up the interception component, the interception function can be realized quickly and conveniently, and good tightness can be ensured to improve the interception effect;

[0035] 2. By setting up the interception component, the device can have a flow regulation function, and the interception plate can be fixed to prevent it from shaking due to the impact of water flow, thereby reducing the risk of damage to the device.

[0036] In summary, the beneficial effects of the utility model are: it can realize the interception function, the flow regulation function, and the interception plate can be fixed to ensure the safe use of the device.
