Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline dredging technology, specifically to a pipeline dredging connector. Background Technology
[0002] Paste backfilling mining is an important future development direction for green mining technology. Paste is transported to the stope over long distances through pipelines. If a section of the pipeline becomes blocked, it requires disconnecting the pipeline and manually knocking it down or using long rods to tamp it down. This process is time-consuming and labor-intensive. If not handled promptly, the entire pipeline is at risk of solidifying and becoming blocked. Pipeline ball unblocking is a solution to this problem. Pipeline ball unblocking typically utilizes the impact or friction generated by the movement of the ball within the pipeline, as well as the squeezing action of the ball on the blockage, to clear the obstruction. The movement of the ball within the pipeline is generally achieved by driving it with high-pressure water.
[0003] However, when the sphere moves in the paste delivery pipe, if no paste or water comes out at the other end of the pipe, the pressure in the pipe will continue to rise and exceed the pressure that the pipe can withstand, which may cause problems such as the pipe cracking. Summary of the Invention
[0004] This invention addresses the problem that increased pressure in pipes during dredging can easily cause pipes to crack. It provides a pipe dredging connector that can stop water delivery when no more paste or water is being dispensed from one end of the pipe, thus preventing the pressure inside the pipe from continuously increasing.
[0005] To solve the above problems, the technical solution of this utility model is:
[0006] A pipe dredging connector includes a power supply device, a connecting pipe, a pump body, and a control component. The right end opening of the connecting pipe is sealed by a sealing plate. The input end of the pump body is connected to the output end of the power supply device via a first wire. The outlet end of the pump body is connected to the inside of the connecting pipe. The control component includes a horizontal pipe and a conductive rod. The left end of the horizontal pipe passes through the sealing plate and is connected to the inside of the connecting pipe. A partition is provided inside the horizontal pipe to divide the inside of the horizontal pipe into a left cavity and a right cavity. A movable plate is slidably provided in the left cavity. An insulating rod is connected to the right side of the movable plate. The right end of the insulating rod is connected to a conductive rod with a free end that moves through the partition. A conductive ring is fixed in the right cavity. The right end of the conductive rod passes through the conductive ring and slides against the inner ring of the conductive ring. A spring is connected between the movable plate and the partition. A limiting component is provided on the horizontal pipe to limit the movement of the insulating rod when it contacts the conductive ring. The conductive ring is connected to the output end of the pump body via a second wire. The right end of the conductive rod is connected to the input end of the power supply device via a third wire.
[0007] Furthermore, a support plate is provided on the right side of the sealing plate, and a pump body is fixed on the support plate.
[0008] Furthermore, the insulating rod and the conductive rod are rectangular rods with the same cross-section, the conductive ring is a rectangular ring, and the length of the insulating rod is less than the length of the conductive rod.
[0009] Furthermore, when the spring is in its natural state, the left and right ends of the conductive rod are located in the left and right cavities, respectively, and the right end of the conductive rod passes through the conductive ring and has a gap to the right end of the horizontal tube.
[0010] Furthermore, the limiting component includes a limiting hole and a limiting rod. The limiting hole is opened on the bottom surface of the insulating rod. The upper end of the limiting rod movably passes through the lower side plate of the horizontal tube on the right side of the partition, and the lower end is connected to a pull plate. A second spring, sleeved outside the limiting rod, is connected between the pull plate and the horizontal tube. The upper end of the limiting rod slides in contact with the bottom surface of the conductive rod, and the second spring is in a stretched state. When the movable plate moves to the right and approaches the partition, and the first spring is compressed to its limit state, the right end of the insulating rod passes through the conductive ring, the upper end of the limiting rod extends into the limiting hole, and the second spring is in a natural state. A vent hole is provided on the lower side plate of the horizontal tube on the left side of the partition, and the vent hole is close to the partition.
[0011] Furthermore, the horizontal tube is an insulated tube made of rubber material, the movable plate is an insulated plate made of rubber material, and the limiting rod is an insulated rod made of rubber material.
[0012] The beneficial effects of this utility model through the above technical solution are as follows:
[0013] In use, the connecting pipe connects to the filling pipe. Initially, the pump body and power supply are connected. The pump body sends water into the filling pipe, and the water in the filling pipe drives the ball to move, cleaning the filling pipe. When no water or paste comes out at the other end of the filling pipe, the pressure in the filling pipe increases, which drives the movable plate to move the insulating rod and the conductive rod to the right until the insulating rod and the conductive ring contact, the pump body is disconnected, and the water supply to the filling pipe is stopped, thus avoiding damage to the filling pipe.

The right end of the conductive rod 6 is connected to the input end of the power supply device 1 via a third wire 14. One end of the third wire is connected to the conductive rod 6, and the other end passes through the right side plate of the horizontal tube 5 and is connected to the input end of the power supply device 1.
[0021] A horizontal support plate 15 is provided on the right side of the sealing plate 4. The support plate 15 is a rectangular plate, and the pump body 3 is fixed on the support plate 15.
[0022] The insulating rod 9 and the conductive rod are rectangular rods with the same cross-section. The conductive ring is a rectangular ring. The insulating rod 9 is a rectangular rod made of rubber material. The conductive rod 6 is a rectangular rod made of iron. The conductive ring 10 is a rectangular ring made of iron. The length of the insulating rod 9 is less than the length of the conductive rod 6.
[0023] When the spring-12 is in its natural state, the left and right ends of the conductive rod 6 are located in the left cavity and the right cavity, respectively. The right end of the conductive rod 6 passes through the conductive ring 10 and has a gap to the right end of the horizontal tube 5.
[0024] The limiting component includes a limiting hole 16 and a limiting rod 17. The limiting hole 16 is formed on the bottom surface of the insulating rod 9. The upper end of the limiting rod 17 movably passes through the lower side plate of the horizontal tube on the right side of the partition 7, and the lower end is connected to a pull plate 19. A spring 18 is connected between the pull plate 19 and the horizontal tube 5 and is sleeved on the limiting rod 17. The upper end of the limiting rod 17 slides in contact with the bottom surface of the conductive rod 6, and the spring 18 is in a stretched state. The movable plate 8 moves to the right to be close to the partition 7, and the spring 18... When compressed to its limit, the right end of the insulating rod 9 passes through the conductive ring 10, the upper end of the limiting rod 17 extends into the limiting hole 16, and the spring 18 is in its natural state. The limiting hole 16 is a circular blind hole with its opening facing downwards, and the limiting rod 17 is a round rod with a diameter matching that of the limiting hole 16. A vent hole 20 is provided on the lower side plate of the horizontal tube on the left side of the partition. The vent hole 20 is close to the partition 7. When the spring 12 is compressed to its limit, the movable plate 8 is located to the left of the vent hole 20.
[0025] The horizontal tube 5 is an insulated tube made of rubber material, the movable plate 8 is an insulated plate made of rubber material, and the limiting rod 17 is an insulated rod made of rubber material.
[0026] In existing technology, the maximum pressure that a pipe filled with paste can withstand is 3.15 × 10⁻⁶. 6 Pa, the spring constant of this utility model - 12 is 1.26 × 10⁻⁶. 5 N / m; The area of the movable plate 8 subjected to water pressure is S = 0.01㎡. When the movable plate 8 moves to the right from the initial state to the limit state, the distance it moves is 0.25m. According to the elastic force formula of spring-12, F = kx, the maximum pressure on the movable plate 8 is F = 3.15 × 10 N / m. 4 At time N, the movable plate 8 can move to the right from its initial state to its limit state. According to the formula for pressure per unit area of an object, P = F / S, the pressure inside the filling pipe reaches 3.15 × 10⁻⁶. 6 When Pa, the moving plate is given F = 3.15 × 10 4 The pressure of N enables the movable plate 8 to move to the right from the initial state to the limit state.
[0027] In use, the water inlet end of the pump body 3 of this utility model is connected to the water supply pipe, and the free end of the connecting pipe 2 is connected to the clogged paste filling pipe. A ball for clearing blockage is inserted into the paste filling pipe.
[0028] Initially, spring 12 is in its natural state. Power supply device 1 provides power. The input end of pump body 3 is connected to the output end of power supply device 1 via wire 11. The output end of pump body 3 is connected to conductive ring 10 via wire 2 13. Conductive rod 6 is connected to the input end of power supply device 1 via wire 3 14. Conductive rod 6 contacts conductive ring 10, and pump body 3 and power supply device 1 are in a closed circuit. Pump body 3 starts, driving water in the water supply pipe to supply water into the paste filling pipe. The water entering the paste filling pipe drives the ball to move, clearing blockages in the paste filling pipe. Because the left end of horizontal pipe 5 is connected to connecting pipe 2, water in the filling pipe enters horizontal pipe 5, and the pressure in the filling pipe is lower than 3.15 × 10⁻⁶. 6 When Pa, the conductive rod 6 remains in contact with the conductive ring 10, and the pump body 3 continuously supplies water into the filling pipe;
[0029] When the paste fills the other end of the pipe but no more paste or water comes out, the pressure inside the pipe rises to 3.15 × 10⁻⁶. 6 When Pa, the movable plate 8 can move from the initial state to the right to the limit state. At this time, the right end of the insulating rod 9 passes through the conductive ring 10, the upper end of the limiting rod 17 extends into the limiting hole 16, the pump body 3 is disconnected, the pump body 3 no longer works, and no longer supplies water to the filling pipeline, so as to avoid the water in the filling pipeline from rising continuously and to avoid the pipeline from cracking.
[0030] After the blockage in the filling pipe is partially cleared by human intervention, the pressure inside the filling pipe decreases. Then, the limit rod 17 is pulled down to disengage from the limit hole. Under the restoring force of the spring 12, the movable plate 8 moves to the left, the conductive rod 6 re-contacts the conductive ring 10, and the pump body 3 resumes operation, supplying water to the filling pipe to continue cleaning it.

Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
