Description

Technical Field

[0001] This utility model belongs to the field of fire protection technology, and in particular relates to a modular and rapid installation structure for fire protection pipelines in pump rooms. Background Technology

[0002] In fire protection systems of industrial and civil buildings, pump rooms serve as the core hub of the fire water system, and the quality of their pipeline installation directly affects fire fighting efficiency and system operational reliability. Fire pipelines within pump rooms are characterized by large diameters, dense layouts, and numerous interfaces. Traditional installation methods rely on manual alignment and bolt tightening, presenting three major technical bottlenecks:

[0003] First, installation efficiency is low. A single flange connection requires at least 4-6 bolts, and tightening them manually one by one is time-consuming, making it difficult to meet the rapid construction needs of modern building projects. Second, installation accuracy depends on experience. Manual operation is easily limited by physical strength and viewing angle, and uneven bolt preload leads to insufficient flange sealing surface fit, causing leaks during water flow testing, requiring multiple rework and adjustments, increasing material and labor costs. Third, the degree of mechanization is low. In existing technologies, some pipeline installation equipment uses a single drive device to tighten bolts one by one, or uses hydraulic clamps to fix a single set of interfaces, but neither solves the problem of multi-bolt linkage drive and synchronous positioning of multiple pipelines. Especially in the confined space of a pump room, the equipment has poor operational flexibility and cannot achieve modular rapid assembly.

[0004] To address these issues, we provide a modular, rapid installation structure for pump room fire protection piping. Utility Model Content

[0005] The purpose of this utility model is to provide a modular and rapid installation structure for fire-fighting pipelines in pump rooms. Through the cooperation of linkage and fixing parts, it solves the problem that in the prior art, fire-fighting pipelines need to be fixed with bolts one by one during installation, which is not only inefficient but also labor-intensive.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a modular rapid installation structure for fire-fighting pipelines in a pump room, comprising a first pipeline and a second pipeline. A modular fixing assembly is fixedly connected between the first pipeline and the second pipeline. The modular fixing assembly includes a linkage component and a fixing component. The linkage component includes a connecting ring sleeved on the surface of the first pipeline. A drive gear ring is fixedly connected to the inner cavity of the connecting ring via a bearing. A driven gear meshes with the inner wall of the drive gear ring, and a drive gear meshes with the surface of the drive gear ring. A transmission shaft is fixedly connected to the top of the drive gear. The fixing component includes a threaded rod fixedly connected to the driven gear and a fixing ring sleeved on the surface of the second pipeline. A threaded tube is threadedly connected to the end of the threaded rod away from the driven gear. A receiving groove is formed in the inner cavity of the fixing ring, and the threaded tube is slidably connected to the inner cavity of the receiving groove.

[0008] The present invention is further configured such that a flange is fixedly connected to one end of the first pipe and the second pipe respectively. The flange has a through hole for threaded rods to pass through on its surface. The edge of the through hole of the flange is chamfered at 45° to facilitate the quick passage of the threaded rods. Combined with the evenly distributed bolt hole design, it ensures the uniformity of force when the pipes are connected.

[0009] The present invention is further configured such that a sealing groove is provided at one end of the first pipe and the second pipe respectively, and a sealing ring is provided in the inner cavity of the sealing groove. The sealing groove has a built-in EPDM rubber sealing ring, which can withstand a water pressure of 1.6MPa when the compression reaches 20%, which significantly improves the waterproof sealing performance of the interface.

[0010] The present invention is further configured such that the linkage component also includes a protective cover threadedly connected to the surface of the connecting ring. The surface of the protective cover has a circular hole through which the drive shaft passes, and the circular hole is fixedly connected to the drive shaft by a bearing. The inner wall of the protective cover is sprayed with an epoxy resin anti-corrosion coating, and the bearing is sealed with lithium-based grease, which effectively resists the corrosion of water vapor and dust in the pump room and reduces the maintenance frequency.

[0011] The present invention is further configured such that a hexagonal groove is provided on the top of the transmission shaft, and the hexagonal groove transmits power to the external drive motor and tool. The hexagonal groove is compatible with mainstream power tools on the market and supports flexible switching between manual and automatic drive modes.

[0012] The present invention is further configured such that a limiting groove is provided in the inner cavity of the receiving groove, a limiting block is slidably connected to the inner cavity of the limiting groove, and the other side of the limiting block is fixedly connected to the surface of the spiral tube. The three-way limiting groove cooperates with the limiting block to restrict the rotational freedom of the spiral tube, ensuring that the axial driving force of the threaded rod is completely converted into the pipe fastening force, and avoiding flange deformation caused by off-center load.

[0013] The present invention is further configured such that the number of limiting grooves is three, and they are distributed at equal intervals around the circumference.

[0014] The present invention is further configured such that there are six threaded rods, which are distributed equidistantly around the circumference. The six threaded rods are evenly distributed around the circumference of the flange to ensure uniform force distribution during pipe connection.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model, through a drive gear-gear ring meshing transmission mechanism, can synchronously drive 6 threaded rods to rotate at a uniform speed, reducing the traditional manual tightening operation to less than 2 minutes, greatly improving the efficiency of single pump room pipeline installation. The coaxial fixed design of the driven gear and threaded rods ensures the consistency of the preload of each bolt and reduces its error. Combined with the sealing ring in the flange sealing groove, the probability of pipeline interface leakage is reduced. The hexagonal groove at the top of the drive shaft is compatible with electric wrenches and hydraulic drive devices, supporting mechanized operation and completely eliminating the dependence on manual experience. It is especially suitable for pump room construction at high altitudes or in confined spaces, freeing operators from high-intensity bending and climbing operations, significantly reducing labor intensity and safety risks.

[0017] 2. The three-way limiting groove in the receiving groove of this utility model allows the spiral tube to move only axially without circumferential rotation, ensuring a small coaxiality error when the pipe is connected. It solves the problem of difficult alignment of flange holes in traditional installation. The protective cover is threaded to the connecting ring, and the internal bearing supports the transmission shaft, effectively isolating the transmission components from the high humidity environment of the pump room and extending the service life of the equipment.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a modular quick-installation structure for fire-fighting pipelines in a pump room, including a first pipeline 1 and a second pipeline 2. A modular fixing component 3 is fixedly connected between the first pipeline 1 and the second pipeline 2. The modular fixing component 3 includes a linkage component 31 and a fixing component 32. The linkage component 31 includes a connecting ring 311 sleeved on the surface of the first pipeline 1. A drive gear ring 312 is fixedly connected to the inner cavity of the connecting ring 311 through a bearing. A driven gear 313 meshes with the inner wall of the drive gear ring 312. A drive gear 314 meshes with the surface of the drive gear ring 312. A transmission shaft 315 is fixedly connected to the top of the drive gear 314. The fixing component 32 includes a threaded rod 321 fixedly connected to the driven gear 313 and a fixing ring 322 sleeved on the surface of the second pipeline 2. A threaded tube 323 is threadedly connected to the end of the threaded rod 321 away from the driven gear 313. A receiving groove 324 is opened in the inner cavity of the fixing ring 322. The threaded tube 323 is slidably connected to the inner cavity of the receiving groove 324.

[0028] Specifically: the connecting ring 311 is a steel ring with an inner diameter that is interference-fitted with the outer diameter of the pipe. The inner wall is inlaid with a deep groove ball bearing, which allows the drive gear ring 312 to rotate freely 360°. The drive gear ring 312 and the drive gear 314 form a meshing transmission to ensure that the threaded rod 321 rotates at a stable speed. One end of the threaded rod 321 is fixed to the driven gear 313 by a flat key, and the other end is screwed into the threaded tube 323. The limiting block 326 on the outer wall of the threaded tube 323 receives the limiting groove 325 of the groove 324 and slides to form an axial guide.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, flanges are fixedly connected to the opposite ends of the first pipe 1 and the second pipe 2. The surface of the flange has a through hole for threaded rod 321. Sealing grooves 4 are provided at the opposite ends of the first pipe 1 and the second pipe 2. Sealing rings 5 ​​are provided in the inner cavity of the sealing grooves 4. The linkage 31 also includes a protective cover 316 that is threadedly connected to the surface of the connecting ring 311. A circular hole for the transmission shaft 315 is provided on the surface of the protective cover 316. The circular hole and the transmission shaft 315 are fixedly connected by a bearing. A hexagonal groove is provided on the top of the transmission shaft 315. The hexagonal groove transmits power to the external drive motor and tools. A limiting groove 325 is provided in the inner cavity of the receiving groove 324. A limiting block 326 is slidably connected in the inner cavity of the limiting groove 325. The other side of the limiting block 326 is fixedly connected to the surface of the threaded tube 323. There are three limiting grooves 325, which are evenly distributed in a circle. There are six threaded rods 321, which are evenly distributed in a circle.

[0031] Specifically: The flange through-hole edge is chamfered at 45° to facilitate the quick passage of the threaded rod 321. Combined with the evenly distributed bolt holes, this ensures uniform stress distribution during pipe connection. The sealing groove 4 has a built-in EPDM rubber sealing ring 5, which can withstand 1.6MPa water pressure when compressed to 20%, significantly improving the waterproof sealing performance of the interface. The inner wall of the protective cover 316 is coated with an epoxy resin anti-corrosion coating. The bearing uses lithium-based grease sealing, effectively resisting water vapor and dust corrosion in the pump room and reducing maintenance frequency. The hexagonal groove is compatible with mainstream power tools on the market, supporting flexible switching between manual and automatic drive modes. The three-way limiting groove 325 cooperates with the limiting block 326 to restrict the rotational freedom of the threaded tube 323, ensuring that the axial driving force of the threaded rod 321 is completely converted into pipe tightening force, avoiding flange deformation caused by uneven load. The six threaded rods 321 are evenly distributed around the circumference of the flange, ensuring uniform stress distribution during pipe connection.

[0032] The working principle of this utility model is as follows: Align the flanges of the first pipe 1 and the second pipe 2, so that the threaded rod 321 passes through the through hole, and the threaded tube 323 is initially inserted into the receiving groove 324 of the fixing ring 322. The limiting block 326 is embedded in the limiting groove 325 to achieve circumferential positioning. An external drive motor or manual wrench applies power through the hexagonal groove at the top of the transmission shaft 315, driving the drive gear 314 to rotate and mesh with the drive gear ring 312, driving the six driven gears 313 to rotate synchronously. The driven gears 313 drive the threaded rod 321 to rotate clockwise, and the threaded tube 323 moves axially along the limiting groove 325, connecting the fixing ring 322 with the connecting... As the connecting ring 311 gradually pulls closer, it presses against the sealing ring 5 on the flange sealing surface, completing the tightening. Under the axial pressure of the threaded tube 323, the sealing ring 5 between the flanges undergoes elastic deformation, forming the first waterproof barrier. The limiting groove 325 and the limiting block 326 prevent the threaded tube 323 from rotating, ensuring that the preload of the threaded rod 321 is evenly transmitted to the flange, avoiding sealing failure caused by local stress concentration. By reversing the drive shaft 315, the threaded tube 323 returns to its initial position, allowing for quick separation of the pipeline. The protective cover 316 can be disassembled separately to lubricate and maintain the bearings and gear sets, ensuring the long-term reliable operation of the linkage mechanism.
