Description

Technical Field

[0001] This application relates to the field of wall penetration protection, specifically a pipeline wall penetration protection device. Background Technology

[0002] In construction projects, some pipelines often need to pass through walls. When pipelines pass through walls, in order to prevent damage to the contact surface between the pipeline and the wall, and also to facilitate subsequent dismantling, protective devices are often installed between the pipeline and the wall.

[0003] Utility model patent CN221402060U discloses a fireproof sealing device for a through-wall sleeve, including a fireproof sleeve, two fire-retardant protective frames, and a fireproof fixing frame that is fixedly connected to the inner wall of the through-wall sleeve body. A fixing mechanism is provided on the outer surface of the fireproof sleeve. A fire-retardant mechanism for fire sealing is provided inside the fire-retardant protective frames. A smoke alarm is installed to provide timely warnings in case of fire. Simultaneously, the combination of the fire-retardant protective frames, movable fireproof plates, and fixing frames provides initial fire retardancy and filtration on the outer surface of the sleeve, and also filters harmful gases generated by building materials, preventing the fire from spreading further through the through-wall sleeve body when it burns. Finally, fire-retardant bags and fire-retardant strips are used to achieve fireproof and heat insulation properties, thereby protecting the wiring inside the sleeve.

[0004] The device is equipped with a fireproof sleeve and a wall-penetrating sleeve body. When protecting pipelines through walls, workers fix the wall-penetrating sleeve body to the wall using a fixing frame. The lines and pipes are installed inside the fireproof sleeve. However, the length of the wall-penetrating sleeve body is fixed, and it can only be installed and fixed in walls of specific thicknesses, so its applicability is limited. Utility Model Content

[0005] To address the issue of limited applicability of existing technologies, this utility model provides a pipeline wall penetration protection device.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a pipe penetration wall protection device, including a clamping plate, a sleeve 1 fixedly installed on one side of the clamping plate, a sleeve 2 slidably installed inside the sleeve 1, a clamping plate 2 fixedly installed at the end of the sleeve 2 away from the sleeve 1, a limiting cylinder fixedly installed on the clamping plate 2, one end of the limiting cylinder located inside the sleeve 2, an installation cavity is formed between the limiting cylinder and the inner wall of the sleeve 2, a through hole 1 is provided inside the limiting cylinder, and a through hole 2 aligned with the through hole 1 is provided on the clamping plate 1;

[0008] It also includes a limiting mechanism, which is disposed in the limiting cylinder.

[0009] Preferably, the limiting mechanism includes a retaining ring, a spring, an adjusting rod, a nut, and a locking block. The retaining ring is located in the mounting cavity and slidably sleeved on the limiting cylinder. A spring is provided on the side of the retaining ring near the locking plate two, and the two ends of the spring are respectively connected and fixed to the limiting cylinder and the retaining ring. The locking plate one has a through hole, and the adjusting rod is inserted into the through hole. One end of the adjusting rod is located in the sleeve one and is fixedly mounted with a locking block. The end of the adjusting rod away from the locking block has a threaded section. The nut is fitted onto the adjusting rod. The retaining ring has a through hole three that matches the locking block. When the sleeve two is slidably sleeved along the sleeve one and the locking plates one and two are respectively in contact with the two sides of the wall, the operator slides the adjusting rod along the through hole to bring the locking block on the adjusting rod closer to the retaining ring in the mounting cavity, ultimately allowing the adjusting rod to move closer to the retaining ring. The locking block on the rod passes through the through hole three on the retaining ring. Then, the worker rotates the adjusting rod, causing the locking block to rotate to a misaligned state with the through hole three. The worker then pulls the adjusting rod, causing the locking block to slide along the limiting cylinder through the misalignment with the through hole three. This causes the retaining ring to stretch the spring. The worker then puts the nut on the adjusting rod and rotates it, so that the nut is in contact with the retaining plate one. The worker then uses an external cutting machine to cut off the section of the adjusting rod outside the nut to prevent the outer end of the adjusting rod from being directly exposed. The nut limits the adjusting rod and the retaining ring, keeping the spring in a stretched state. The spring's pull on the retaining ring and the limiting cylinder ensures the stability of the retaining plates one and two against the wall.

[0010] Preferably, the locking block is in the shape of a straight line. By setting the locking block in the shape of a straight line, it is convenient for the operator to switch the staggered state of the locking block and the through hole three when rotating the adjusting rod.

[0011] Preferably, the springs and through holes are arranged in multiple sets at intervals along the circumference of the retaining ring. By setting multiple sets of springs and through holes, the retaining ring can be limited at multiple points, ensuring the stability of the retaining ring when it slides.

[0012] Preferably, the outer wall of the limiting cylinder is fixedly provided with a locking strip, and the retaining ring is provided with a retaining groove that matches the locking strip. The locking strip and the retaining groove further limit the retaining ring and ensure the stability of the retaining ring when it slides.

[0013] Preferably, a sleeve is fixedly provided at one end of the card plate one inside the sleeve one. The sleeve is slidably sleeved on the limiting cylinder. The sleeve provided on the card plate one enables the through hole one to be directly connected to the through hole two through the sleeve, ensuring the safety of the pipeline.

[0014] Preferably, a retaining strip 2 is fixedly provided on the outer wall of the sleeve 2, and a retaining groove 2 is provided on the sleeve 1 to match the retaining strip 2. By setting the retaining strip 2 and the retaining groove 2, the sleeve 2 is further limited, ensuring the stability of the sleeve 2 sliding inside the sleeve 1.

[0015] The advantages of adopting the above technical solution are:

[0016] This utility model includes a first clamping plate, a first sleeve fixedly mounted on one side of the first clamping plate, a second sleeve slidably mounted inside the first sleeve, a second clamping plate fixedly mounted at the end of the second sleeve away from the first sleeve, a limiting cylinder fixedly mounted on the second clamping plate, one end of the limiting cylinder located inside the second sleeve, forming an installation cavity between the limiting cylinder and the inner wall of the second sleeve, a first through hole provided inside the limiting cylinder, and a second through hole provided on the first clamping plate aligned with the first through hole. In this device, the operator can slide the first sleeve and the second sleeve onto each other to adjust the distance between the first clamping plate and the second clamping plate, thereby effectively isolating pipelines and perforations on walls of different thicknesses, thus improving the applicability.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1-4As shown in the figure, this utility model embodiment discloses a pipeline through-wall protection device, including a clamping plate 1 and a limiting mechanism. A sleeve 2 is fixedly provided on one side of the clamping plate 1. A sleeve 3 is slidably sleeved inside the sleeve 2. A clamping plate 4 is fixedly provided at the end of the sleeve 3 away from the sleeve 2. A limiting cylinder 5 is fixedly provided on the clamping plate 4. One end of the limiting cylinder 5 is located inside the sleeve 3. An installation cavity 302 is formed between the limiting cylinder 5 and the inner wall of the sleeve 3. A through hole 501 is provided inside the limiting cylinder 5. A through hole 2 aligned with the through hole 501 is provided on the clamping plate 1. The limiting mechanism is provided on the limiting cylinder 5.

[0025] In at least one embodiment, the limiting mechanism includes a retaining ring 6, a spring 601, an adjusting rod 7, a nut 702, and a locking block 701. The retaining ring 6 is located in the mounting cavity 302 and slidably sleeved on the limiting cylinder 5. A spring 601 is provided on the side of the retaining ring 6 near the second locking plate 4. The two ends of the spring 601 are respectively connected and fixed to the limiting cylinder 5 and the retaining ring 6. The first locking plate 1 has a through hole, and the adjusting rod 7 is inserted into the through hole. One end of the adjusting rod 7 is located in the first sleeve 2 and is fixedly provided with the locking block 701. The end of the adjusting rod 7 away from the locking block 701 has a threaded section. The nut 702 is fitted onto the adjusting rod 7. The retaining ring 6 has a through hole 602 that matches the locking block 701. When the second sleeve 3 is slidably sleeved along the first sleeve 2 and the first locking plate 1 and the second locking plate 4 are respectively attached to the two sides of the wall, the operator slides the adjusting rod 7 along the through hole so that the locking block 701 on the adjusting rod 7 is close to the retaining ring 6 in the mounting cavity 302. Finally, the locking block 701 on the adjusting rod 7 passes through the through hole 602 on the retaining ring 6. Then, the worker rotates the adjusting rod 7, causing the locking block 701 to rotate to a misaligned state with the through hole 602. The worker then pulls the adjusting rod 7, causing the locking block 701 to slide along the limiting cylinder 5 due to the misalignment with the through hole 602. The retaining ring 6 then stretches the spring 601. The worker then puts the nut 702 on the adjusting rod 7 and rotates it, so that the nut 702 fits against the retaining plate 1. The worker then uses an external cutting machine to cut the section of the adjusting rod 7 outside the nut 702 to prevent the outer end of the adjusting rod 7 from being directly exposed. The nut 702 limits the adjusting rod 7 and the retaining ring 6, so that the spring 601 is always in a stretched state. The pull of the spring 601 on the retaining ring 6 and the limiting cylinder 5 ensures the stability of the retaining plate 1 and retaining plate 2 against the wall.

[0026] In at least one embodiment, the locking block 701 is in the shape of a straight line. By setting the locking block 701 in the shape of a straight line, it is convenient for the operator to switch the staggered state of the locking block 701 and the through hole 602 when rotating the adjusting rod 7.

[0027] In at least one embodiment, multiple sets of springs 601 and through holes 602 are arranged at intervals along the circumference of the retaining ring 6. By setting multiple sets of springs 601 and through holes 602, the retaining ring 6 is limited at multiple points, ensuring the stability of the retaining ring 6 when it slides.

[0028] In at least one embodiment, a retaining strip is fixedly provided on the outer wall of the limiting cylinder 5, and a retaining ring 6 is provided with a retaining groove 603 that matches the retaining strip. The retaining strip and the retaining groove 603 further limit the retaining ring 6 and ensure the stability of the retaining ring 6 when it slides.

[0029] In at least one embodiment, a sleeve 8 is fixedly provided at one end of the card plate 1 inside the sleeve 2. The sleeve 8 is slidably sleeved on the limiting cylinder 5. By using the sleeve 8 provided on the card plate 1, the through hole 501 is directly connected to the through hole 2 through the sleeve 8, thus ensuring the safety of the pipeline.

[0030] In at least one embodiment, a retaining strip 301 is fixedly provided on the outer wall of the sleeve 2 3, and a retaining groove 201 is provided on the sleeve 1 2 to match the retaining strip 301. By setting the retaining strip 301 and the retaining groove 201, the sleeve 2 3 is further limited, ensuring the stability of the sleeve 2 3 sliding inside the sleeve 1 2.

[0031] During the wall penetration protection work for pipelines, the workers will insert sleeve 2 on clamp 1 and sleeve 3 on clamp 4 into the wall penetration on both sides, allowing sleeve 3 to slide into sleeve 2. Then, they will continue to slide sleeves 2 and 3 until the distance between clamp 1 and clamp 4 is the same as the wall thickness, ensuring that clamp 1 and clamp 4 are each fitted against one side of the wall. The pipeline will then be laid along through hole 2 and through hole 501. The through-wall installation allows for the routing of pipelines through walls. Sleeve 1 2 and Sleeve 2 3 isolate the pipelines from the wall, preventing direct contact between the pipelines and the wall at the perforation point, thus protecting the pipelines' safety. Furthermore, the sliding sleeves 1 2 and Sleeve 2 3 can provide protection for perforations in walls of varying thicknesses, expanding the applicability. The limiting mechanism inside the limiting cylinder 5 can limit the positions of clamping plates 1 1 and 2 4, ensuring convenient operation and guaranteeing the stability of clamping plates 1 1 and 2 4 in contact with the wall.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
