Description

Technical Field

[0001] The present invention belongs to the technical field of indoor pipelines, and particularly relates to a pipeline protection device for indoor prefabricated water and electricity installation with a moisture-proof function. Background Art

[0002] Indoor pipelines include electric wires, water pipelines, network cables, and fire pipelines, etc. Indoor pipelines are generally installed and fixed according to safety and the living habits of residents, which is convenient for residents to use and also helps to ensure safety and convenience. At the same time, these pipelines are divided into surface laying and concealed laying, and are installed according to needs.

[0003] In the past, people's operation on cable joints was to remove some of the insulation layers of two cables, then wind and twist the two copper wires together, and finally wrap the joint part with insulating tape to prevent leakage. However, the insulating tape is vulnerable to the external environment and is also prone to aging and losing its stickiness. The connection head will be wet and leak electricity after long-term use, leading to safety accidents. And due to the gaps between the joints, electric arcs are likely to be generated. Under the long-term burning of the electric arcs, the joints are likely to break, and in severe cases, parallel connection and other electricity-using accidents will also be caused. Therefore, there is an urgent need in the current market for a pipeline protection device for indoor prefabricated water and electricity installation with a moisture-proof function to solve the above problems.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, through the mutual cooperation of the structures such as the first protective sleeve, the second protective sleeve, the first extrusion sleeve, the second extrusion sleeve, the first support spring, the fixing clip, the fixing medium, the waterproof sealing ring and the moisture-absorbing filler, it is possible to prevent the two from falling off due to external adverse factors such as vibration. The provided first support spring has a shock absorption effect and is used to improve the stability of the stranded part of the cable joint between the first extrusion sleeve and the second extrusion sleeve. The two arc extinguishing methods complement each other, so that a good arc extinguishing effect can be achieved, avoiding electric arc breakdown of the first extrusion sleeve, the second extrusion sleeve, the first protective cover and the second protective cover and causing power accidents such as short circuit, and also avoiding the waterproof sealing ring being dried by the heat energy emitted inside the first protective sleeve and the second protective sleeve, ensuring the normal service life of the waterproof sealing ring.

[0027] 2. In the present invention, the first protective sleeve, the second protective sleeve, the first extrusion sleeve, the second extrusion sleeve, the first support spring and the fixing clip are designed, and the first hinge is used as a connecting medium between the first protective sleeve and the second protective sleeve, so that the two can be opened and closed. The fixing clips on the first protective sleeve and the second protective sleeve are used to squeeze and fix the two cables that are twisted between the two, which can prevent the two from falling off due to adverse external factors such as vibration. The first support spring has a shock-absorbing effect, which is used to improve the stability of the cable joint twisted part between the first extrusion sleeve and the second extrusion sleeve.

[0028] 3. In the present invention, by designing the first extrusion sleeve, the second extrusion sleeve, the fixing clamp and the fixing medium, the first extrusion sleeve and the second extrusion sleeve are combined and connected into an integrated structure to form a structure similar to an arc extinguishing cover, and with the help of the fixing medium between the fixing clamps, the arc generated at the twisted wire part of the cable joint can be elongated, thereby achieving a certain arc extinguishing effect and preventing the first extrusion sleeve, the second extrusion sleeve, the first protective cover and the second protective cover from being punctured by the arc.

[0029] 4. In the present invention, the first pin shaft, the second pin shaft, the connecting shaft, the fixed seat, the movable seat, the piston sleeve and the sealing gasket are designed. The sealing gasket is used to improve the sealing performance between the cable surface and the inner wall of the piston sleeve. In the process of closing the first protective sleeve and the second protective sleeve, the first extrusion sleeve will first contact the second extrusion sleeve. In the process of continuing to close the second protective sleeve and the first protective sleeve, since the two ends of the connecting shaft can respectively rotate with the first pin shaft and the second pin shaft as the center of the circle, the piston sleeve can be driven to move outward. Under the effect of the piston sleeve, the cavity surrounded by the first extrusion sleeve and the second extrusion sleeve can be in a negative pressure state. In the process of pulling the piston sleeve to slide through the connecting ring, the piston is also pulled by the pull rod to perform a corresponding sliding action in the piston hole, which can further increase the negative pressure inside the first extrusion sleeve and the second extrusion sleeve, and can play a certain effect similar to vacuum arc extinguishing. The two arc extinguishing methods complement each other, so that a good arc extinguishing effect can be achieved, avoiding the first extrusion sleeve, the second extrusion sleeve, the first protective cover and the second protective cover from being punctured by the arc and causing power accidents such as paralleling.

[0030] 5. In the present invention, through the designed bolts, connecting holes and threaded holes, the threaded connection relationship between the first protective sleeve and the second protective sleeve, between the second protective clamp and the second protective clamp, and between the corresponding two locking sleeves is ensured by the threaded connection relationship between the threaded holes and the bolts, so as to ensure the stability relationship between the two corresponding ones.

[0031] 6. In the present invention, through the designed waterproof sealing ring and moisture-absorbing filler, the waterproof sealing ring can be used to prevent the infiltration of humid air through the connection part between the cable and the lock sleeve. The moisture-absorbing filler is used to absorb the moisture in the air. On the one hand, it can improve the sealing effect of the waterproof sealing ring on the moisture in the air. On the other hand, it can provide a certain amount of moisture for the waterproof sealing ring to avoid being dried by the heat energy emitted inside the first protective sleeve and the second protective sleeve, ensuring the normal service life of the waterproof sealing ring.

[0032] 7. In the present invention, through the designed shape memory alloy connector, the shape memory alloy connector serves as the connection medium between the first protective sleeve and the second protective sleeve and the corresponding first protective clip and second protective clip, enabling a cornering action to occur during the wire threading process, effectively ensuring the smoothness during the wire threading process.

After being combined and connected into an integrated structure, a structure similar to an arc-extinguishing cover can be formed, and with the help of the fixing medium between the fixing clamps 6, the arc generated at the twisted wire part of the cable joint can be elongated, thereby achieving a certain arc-extinguishing effect, and preventing the first extrusion sleeve 3, the second extrusion sleeve 4, the first protective cover and the second protective cover from being punctured by the arc. The inner side walls of the second protective cover 2 and the first protective cover 1 are fixedly connected with the fixing clamps 6, and a solid medium 7 is arranged between two adjacent fixing clamps 6. The first protective cover 1 and the second anti-slip cover are provided with a piston sleeve 8, and the side end faces of the second protective cover 2 and the first protective cover 1 are fixedly connected with a memory joint. The memory alloy connector 25 is designed as a connection medium between the first protective sleeve 1 and the second protective sleeve 2 and the corresponding first protective clip 26 and the second protective clip 27, so that the threading process can be turned, which effectively ensures the smoothness of the threading process. The first protective clip 26 and the second protective clip 27 are fixedly connected to the side of the two memory alloy connectors 25 away from the first protective sleeve 1 and the second protective sleeve 2, respectively, and the second protective clip 27 and the first protective clip 26 are fixedly connected to the side of the memory alloy connector 25 away from the memory alloy connector 25. The lock sleeve 28 is fixedly connected to the side of the memory alloy connector 25. The first protective sleeve 1, the second protective sleeve 2, the first extrusion sleeve 3, the second extrusion sleeve 4, the first support spring 5 and the fixing clamp 6 are designed. The first protective sleeve 1 and the second protective sleeve 2 are connected by a first hinge 21 so that the two can be opened and closed. The two cables located between the first protective sleeve 1 and the second protective sleeve 2 are squeezed and fixed by the fixing clamp 6 on the first protective sleeve 1 and the second protective sleeve 2 after being twisted, so as to prevent the two cables from falling off due to adverse external factors such as vibration. The first support spring 5 has a shock-absorbing effect, and is used to improve the stability of the cable joint twisted wire part between the first extrusion sleeve 3 and the second extrusion sleeve 4.

[0046] Specifically, Figure 2 As shown, a connecting ring 9 is provided on one side of the piston sleeve 8 away from the first protective sleeve 1 and the second protective sleeve 2, and a movable seat 12 is fixedly connected to the surface of the connecting ring 9 at positions corresponding to the second protective sleeve 2 and the first protective sleeve 1, and a fixed seat 11 is fixedly connected to the inner side walls of the first protective sleeve 1 and the second protective sleeve 2 at positions corresponding to the movable seat 12.

[0047] Specifically, as Figure 2 shown, the front of the fixed seat 11 is hinged to one end of the back of the connecting shaft 14 through the first pin shaft 13, and the other end of the back of the connecting shaft 14 is hinged to the adjacent side of the movable seat 12 through the second pin shaft 15. Through the designed first pin shaft 13, second pin shaft 15, connecting shaft 14, fixed seat 11, movable seat 12, piston sleeve 8 and gasket 10, the gasket 10 is used to improve the sealing performance between the surface of the cable and the inner wall of the piston sleeve 8. During the process of closing the first protective sleeve 1 and the second protective sleeve 2, the first pressing sleeve 3 will first come into contact with the second pressing sleeve 4. During the continuous closing process of the second protective sleeve 2 and the first protective sleeve 1, since the two ends of the connecting shaft 14 can rotate respectively around the first pin shaft 13 and the second pin shaft 15, therefore, it can drive the piston sleeve 8 to move outward. Under the action of the piston sleeve 8, the cavity formed by the first pressing sleeve 3 and the second pressing sleeve 4 can be in a negative pressure state. And during the process of pulling the piston sleeve 8 to slide through the connecting ring 9, the piston 18 will also be pulled by the pull rod 20 to perform corresponding sliding actions in the piston hole 16, which can further improve the negative pressure inside the first pressing sleeve 3 and the second pressing sleeve 4, and can play a certain effect similar to vacuum arc extinguishing. The two arc extinguishing methods complement each other, so that a good arc extinguishing effect can be achieved, and it can prevent the first pressing sleeve 3, the second pressing sleeve 4, the first protective cover and the second protective cover from being broken through by the arc and causing electrical accidents such as short circuit of wires.

[0048] Specifically, as Figure 4 shown, a piston hole 16 is provided at the side end face of the piston sleeve 8 corresponding to the position of the connecting ring 9. A support mesh seat 17 is fixedly connected inside the piston hole 16, and a piston 18 is sleeved inside the piston hole 16 corresponding to the position of the support mesh seat 17. The opposite surfaces of the piston 18 and the support mesh seat 17 are fixedly connected through the second support spring 19.

[0049] Specifically, as Figure 4 shown, a pull rod 20 is sleeved inside the piston hole 16. One end of the pull rod 20 is fixedly connected to the side close to the piston 18, and the other end of the pull rod 20 is fixedly connected to the side close to the connecting ring 9.

[0050] Specifically, as Figure 8 shown, the rear side edges of the opposite surfaces of the first protective sleeve 1 and the second protective sleeve 2 are hinged through the first hinge 21, and the rear side edges of the opposite surfaces of the second protective clip 27 and the second protective clip 27 are hinged through the second hinge 29.

[0051] Specifically, as Figure 9As shown in the figure, threaded holes 22 are provided on the upper end surfaces of the first protective sleeve 1 and the first protective clip 26. And connection holes 23 are provided at positions corresponding to the threaded holes 22 on the second protective sleeve 2 and the second anti-slip clip surface. Bolts are sleeved in the connection holes 23, and the surface of the bolt 24 is threadedly connected to the inner side wall of the threaded hole 22. Through the designed bolt 24, connection hole 23 and threaded hole 22, the threaded connection relationship between the threaded hole 22 and the bolt 24 is adopted between the first protective sleeve 1 and the second protective sleeve 2, between the second protective clip 27 and the second protective clip 27, and between the corresponding two locking sleeves 28, ensuring the stability relationship between the corresponding two.

[0052] Specifically, as Figure 5 shown, waterproof sealing rings 30 are provided on the inner side walls of the first protective clip 26 and the second anti-slip clip. And moisture-absorbing fillers 31 are provided on the inner side wall of the locking sleeve 28 at positions corresponding to the waterproof sealing rings 30. Through the designed waterproof sealing rings 30 and moisture-absorbing fillers 31, the waterproof sealing rings 30 can be used to prevent the infiltration of humid air through the connection part between the cable and the locking sleeve 28. The moisture-absorbing fillers 31 are used to absorb the moisture in the air. On the one hand, it can improve the sealing effect of the waterproof sealing rings 30 on the moisture in the air. On the other hand, it can provide a certain amount of moisture for the waterproof sealing rings 30 to avoid being dried by the heat energy emitted inside the first protective sleeve 1 and the second protective sleeve 2, ensuring the normal service life of the waterproof sealing rings 30.

[0053] Specifically, as Figure 5 shown, a sealing gasket 10 is provided on the inner side wall of the piston sleeve 8, and the sealing gasket 10 has good elasticity and sealing performance.

[0054] Specifically, as Figure 1 shown, the first extrusion sleeve 3 and the second extrusion sleeve 4 are both elastic insulating sleeves, and the vertical cross-sections of the first extrusion sleeve 3 and the second extrusion sleeve 4 are both arc-shaped, which is beneficial for the first extrusion sleeve 3 and the second extrusion sleeve 4 to be extruded and fixed, and can prevent electric leakage.

[0055] Working principle: When in use, the first hinge 21 is used as a connecting medium between the first protective sleeve 1 and the second protective sleeve 2, so that the two can be opened and closed. The fixing clips 6 on the first protective sleeve 1 and the second protective sleeve 2 are used to squeeze and fix the two cables that are twisted between the two, so as to prevent the two from falling off due to adverse external factors such as vibration. The first supporting spring 5 has a shock-absorbing effect, which is used to improve the stability of the cable joint stranded part between the first extrusion sleeve 3 and the second extrusion sleeve 4. After the first extrusion sleeve 3 and the second extrusion sleeve 4 are combined and connected into an integrated structure, a structure similar to an arc extinguishing cover can be formed, and the fixing medium between the fixing clips 6 can absorb the shock generated by the cable joint stranded part. The arc is elongated, so that a certain arc extinguishing effect can be achieved, and the first extrusion sleeve 3, the second extrusion sleeve 4, the first protective cover and the second protective cover are prevented from being punctured by the arc. The sealing gasket 10 is used to improve the sealing performance between the cable surface and the inner wall of the piston sleeve 8. In the process of closing the first protective sleeve 1 and the second protective sleeve 2, the first extrusion sleeve 3 will first contact the second extrusion sleeve 4. In the process of continuing to close the second protective sleeve 2 and the first protective sleeve 1, since the two ends of the connecting shaft 14 can rotate with the first pin shaft 13 and the second pin shaft 15 as the center of the circle, the piston sleeve 8 can be driven to move outward. Under the effect of the piston sleeve 8, the cavity surrounded by the first extrusion sleeve 3 and the second extrusion sleeve 4 can be in a state of negative pressure. In the process of pulling the piston sleeve 8 to slide through the connecting ring 9, the piston 18 will be pulled by the pull rod 20 to perform a corresponding sliding action in the piston hole 16, which can further increase the negative pressure inside the first extrusion sleeve 3 and the second extrusion sleeve 4, and can play a certain effect similar to vacuum arc extinguishing. The two arc extinguishing methods complement each other, so that a good arc extinguishing effect can be achieved, avoiding the first extrusion sleeve 3, the second extrusion sleeve 4, the first protective cover and the second protective cover from being pierced by the arc and causing power accidents such as parallel lines. The threaded connection relationship between the threaded hole 22 and the bolt 24 is adopted between the first protective cover 1 and the second protective cover 2, between the second protective clip 27 and the second protective clip 27, and between the corresponding two locking sleeves 28 to ensure that the corresponding two Stability relationship, the waterproof sealing ring 30 can be used to prevent humid air from infiltrating through the connection between the cable and the locking sleeve 28, and the hygroscopic filler 31 is used to absorb moisture in the air. On the one hand, it can improve the sealing effect of the waterproof sealing ring 30 on moisture in the air. On the other hand, it can provide a certain amount of moisture for the waterproof sealing ring 30 to avoid being dried by the heat energy emitted from the first protective sleeve 1 and the second protective sleeve 2, thereby ensuring the normal service life of the waterproof sealing ring 30. The memory alloy connector 25 serves as a connecting medium between the first protective sleeve 1 and the second protective sleeve 2 and the corresponding first protective clip 26 and the second protective clip 27, so that a turning action can occur during the threading process, effectively ensuring the smoothness of the threading process.
