Description

TECHNICAL FIELD

[0001] The utility model relates to electromechanical installation technical field, concretely relates to the electrical pipeline connection integrated connection assembly of hidden laying. BACKGROUND

[0002] In modern construction engineering, the installation quality and efficiency of electrical system have a very key influence on the functionality, safety and subsequent operation and maintenance of the whole building. As an important link of electrical system installation, the connection of open assembly distribution box and hidden laying electrical pipeline, especially the hidden laying pipeline in water environment, gradually exposes a series of problems in the traditional construction method, which promotes the research and application of integrated connection assembly.

[0003] The traditional construction of open assembly distribution box and hidden laying electrical pipeline connection usually cuts, bends and connects the electrical pipeline on site after the distribution box is in place to realize the butt joint with the distribution box. This process highly depends on the manual skills and experience of construction personnel, and has many disadvantages.

[0004] Firstly, the construction precision is difficult to guarantee. Due to the complex construction site environment and many interference factors, it is difficult for construction personnel to accurately control the connection angle, depth and position relationship when connecting the pipeline and the distribution box. For example, when determining the depth of pipeline insertion into the distribution box, it may be too deep or too shallow due to measurement error or improper operation. Too deep may affect the layout and normal operation of internal components of the distribution box, and even cause line extrusion damage; too shallow may cause loose connection, easy to fall off, and cause electrical failure, such as heating and sparking caused by poor contact, which seriously affects the stability and reliability of the electrical system.

[0005] Secondly, the construction efficiency is low. The traditional connection method involves a lot of on-site processing and adjustment work, and each connection point needs to spend more time. From the port processing of the pipeline, the butt joint installation with the distribution box to the quality inspection and adjustment after connection, the process is complicated and complex. Especially in large-scale construction engineering, the number of distribution boxes and electrical pipelines is large, and this inefficient construction method will significantly prolong the construction period and increase the time cost of the project.

[0006] Furthermore, construction quality varies considerably. The skill levels and work attitudes of different construction workers differ, making it difficult to maintain consistent results even under the same construction standards. In traditional connection processes, the lack of standardized connection components and standardized operating procedures easily leads to problems such as unstable welding quality, loose threaded connections, and poor sealing performance. These quality issues may not be apparent in the short term, but as the building ages, the failure rate of the electrical system will gradually increase, posing significant challenges to later maintenance and repair. For example, poor sealing performance can allow moisture, dust, and other impurities to enter the distribution box or electrical conduit, potentially corroding wiring and components, reducing their lifespan, and increasing maintenance costs and replacement frequency.

[0007] Furthermore, traditional construction methods result in significant material waste. Due to the numerous uncertainties inherent in on-site processing and adjustments, a certain amount of material surplus needs to be reserved to handle various possible situations. For example, when cutting electrical conduits, multiple cuts may be required due to inaccurate initial cuts, leading to material waste; similarly, when remaking connecting components after a connection failure, the original materials are often unusable. This material waste not only increases the project's material costs but also contradicts the concept of sustainable development in modern construction engineering.

[0008] With the continuous development of the construction industry, the quality requirements for building electrical installation projects are becoming increasingly stringent. Simultaneously, to improve construction efficiency, reduce costs, minimize resource waste, and enhance the overall performance and safety of building electrical systems, the development of an integrated connection component for connecting surface-mounted electrical boxes to concealed electrical conduits has become an urgent need in the building electrical field. This integrated connection component aims to achieve precise, efficient, and reliable connections through standardized design and factory production, overcoming many shortcomings of traditional construction methods. It provides a new and more optimized solution for the installation of building electrical systems, especially for concealed conduits in water-related environments. Utility Model Content

[0009] The purpose of this utility model is to provide an integrated connection component for concealed electrical conduit connections, which aims to improve the problem of unreliable construction quality during the electrical conduit connection process.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An integrated connection component for concealed electrical conduit connections includes a pre-embedded pipe, a first junction box, and a second junction box. A connecting hole is provided on one wall of both the first and second junction boxes. One end of the pre-embedded pipe is connected to the connecting hole of the first junction box, and the other end is connected to the connecting hole of the second junction box.

[0012] Furthermore, a cable is installed inside the pre-embedded pipe, with one end of the cable extending into the first junction box and the other end extending into the second junction box.

[0013] Furthermore, the interior of the pre-embedded pipe, the first junction box, and the second junction box are all coated with moisture-proof and insulating paint.

[0014] Furthermore, it also includes a distribution box, wherein an installation groove is provided on the outer rear wall of the distribution box, the first junction box is located in the installation groove, a wire through hole is provided on the inner bottom wall of the installation groove, and the first junction box and the installation groove of the distribution box are sealed together.

[0015] Furthermore, the first junction box is filled with fire-retardant sealant, and one end of the cable located inside the first junction box extends into the distribution box through a wire hole.

[0016] Furthermore, the pre-embedded pipe includes a first pipe segment and a second pipe segment, one end of the first pipe segment is connected to one end of the second pipe segment, and the first pipe segment and the second pipe segment are perpendicular to each other, and the inner side of the connection between the first pipe segment and the second pipe segment is chamfered.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Utilizing BIM technology during the construction preparation phase, the locations of the distribution box and submersible pump are accurately determined, as well as the routing of concealed conduits. Employing integrated prefabrication technology, the first junction box, second junction box, and concealed galvanized steel embedded conduits are manufactured as a single unit. Cables are threaded into the embedded conduits, with both ends of the cables located in their corresponding junction boxes. The first junction box connects to the distribution box and is filled with sealant. One end of the cable inside the first junction box extends outside the sealant. After the submersible pump cable is connected to the cable at one end in the second junction box, sealant is filled into the second junction box to prevent humid air from entering through the pipe joints, thus improving the quality of electrical conduit connection construction. A tight seal is formed at the connection between the electrical conduits and the submersible pump. This sealing design effectively prevents sewage, water vapor, dust, and other impurities from entering the electrical system, protecting the insulation performance of wires and electrical equipment.

[0019] 2. Precise Positioning: During factory prefabrication, the integrated connection components are designed to precisely match the electrical interfaces of the submersible pump and the concealed electrical conduits, ensuring a perfect fit. During installation, the components can be precisely positioned and connected, avoiding the positional deviations between the conduits and the pump body's electrical interfaces caused by manual measurement and on-site processing errors in traditional connection methods.

[0020] 3. Simplified Installation Process: Traditional submersible sewage pump electrical wiring connections require multiple complex steps on-site, including pipe cutting, threading, welding (if necessary), and connection and debugging to the pump body. Each step requires repeated measurement and adjustment. Integrated connection components pre-complete these steps in the factory, requiring only simple component installation and connection on-site. For example, previously, installing the electrical wiring for a single submersible sewage pump might have required 2-3 workers and 2-3 hours. With integrated connection components, installation can be completed by only 1-2 workers in about 1 hour, significantly reducing installation time and improving construction efficiency.

[0021] 4. Reduced on-site adjustments and rework: Due to the high precision and standardization of the integrated connection components, on-site adjustments or rework are rarely required during installation due to connection mismatches or quality issues. This contrasts sharply with traditional installation methods, which often require multiple reworks to meet requirements due to various errors and uncertainties.

[0022] 5. Easy to troubleshoot: When the electrical system of the submersible sewage pump malfunctions, the standardized structure of the integrated connection assembly makes troubleshooting much easier. Maintenance personnel can quickly locate the connection assembly and determine the cause of the fault by checking its connection status, sealing condition, and internal wiring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] An integrated connection component for concealed electrical conduit installation, as described in the following example. Figure 1 , Figure 2 It includes a pre-embedded pipe 1, a first junction box 2 and a second junction box 3. A connecting hole is opened on one wall of the first junction box 2 and the second junction box 3. One end of the pre-embedded pipe 1 is connected to the connecting hole of the first junction box 2 and the other end is connected to the connecting hole of the second junction box 3.

[0031] Furthermore, a cable is threaded through the pre-embedded conduit 1, with one end of the cable extending into the first junction box 2 and the other end extending into the second junction box 3. Threading a slightly longer cable according to the length of the pre-embedded conduit 1 helps reduce waste of cable materials.

[0032] Furthermore, the interiors of the embedded pipe 1, the first junction box 2, and the second junction box 3 are all coated with moisture-proof insulating varnish. This moisture-proof insulating varnish forms a continuous protective film on the inner wall of the pipe, preventing moisture from contacting the metal surface and simultaneously improving insulation performance.

[0033] Furthermore, the integrated connection component for concealed electrical conduit connections also includes a distribution box 4. A mounting groove 5 is formed on the outer rear wall of the distribution box 4. The first junction box 2 is located within the mounting groove 5. A wire-passing hole 6 is formed on the inner bottom wall of the mounting groove 5. The first junction box 2 and the mounting groove 5 of the distribution box 4 are sealed together. The distribution box 4 is customized, taking into account the dimensions of the pre-embedded first junction box 2, and an embedded mounting groove 5 is formed on its back. During installation, the mounting groove 5 is filled with fire-retardant sealant to fully bond with the outer wall of the protruding portion of the first junction box 2.

[0034] Furthermore, the first junction box 2 is filled with fire-retardant sealant, and one end of the cable inside the first junction box 2 extends to the outside of the fire-retardant sealant and then extends through the wire hole 6 to the inside of the distribution box 4.

[0035] Furthermore, the pre-embedded pipe 1 includes a first pipe section 7 and a second pipe section 8. One end of the first pipe section 7 is connected to one end of the second pipe section 8, and the first pipe section 7 and the second pipe section 8 are perpendicular to each other. The inner side of the connection between the first pipe section 7 and the second pipe section 8 is chamfered to facilitate the installation of cables. The first pipe section 7 is connected to the first junction box 2, and the second pipe section 8 is connected to the second junction box 3. During pre-embedding, the first pipe section 7 is vertically buried inside the wall, while the second pipe section 8 is horizontally buried in the ground, so that the open side of the first junction box 2 protrudes outside the wall, and the open side of the second junction box 3 is located on the side wall of the sump 9 to facilitate the connection of the submersible pump 10 to the distribution box 4.

[0036] During the construction preparation phase, BIM technology was used to accurately determine the locations of the distribution box 4 and the submersible sewage pump 10, as well as the route of the concealed piping. Utilizing prefabrication plant integrated production technology, the first junction box 2, the second junction box 3, and the concealed galvanized steel embedded pipe 1 were manufactured as a single unit. The cable was threaded into the embedded pipe 1, with both ends of the cable located within their respective junction boxes. The first junction box 2 was used to connect to the distribution box 4. Sealant was filled inside the first junction box 2, with one end of the cable extending outside the sealant. After the cable of the submersible sewage pump 10 was connected to the end of the cable located in the second junction box 3, sealant was filled into the second junction box 3 to prevent humid air from entering through the pipe connection, thus improving the quality of electrical conduit connection construction. A tight seal was formed at the connection between the electrical conduit and the submersible sewage pump 10. This sealing design effectively prevents sewage, water vapor, dust, and other impurities from entering the electrical system, protecting the insulation performance of the wires and electrical equipment.

[0037] The manufacturing and installation process of the integrated connection component for concealed electrical conduit connections includes the following steps: construction preparation → integrated conduit fabrication → distribution box 4 customization → flexible waterproof hose 11 fabrication → integrated conduit pre-embedding → distribution box 4 installation → submersible sewage pump 10 installation → submersible sewage pump 10 wiring.

[0041] (3) Customization of distribution box 4: Conventional distribution box 4 has top and bottom entry and exit. In this scheme, the distribution box 4 enters from the back. The mounting groove 5 is cut out in the shape of the first junction box 2 at the bottom of the back of the distribution box 4. A wire hole 6 with a diameter of 3cm is opened in the center of the mounting groove 5.

[0042] (4) Flexible waterproof hose 11 fabrication: On the basis of the original equipment’s own cable, wrap it with insulating tape, then cover it with fire-resistant and moisture-proof hose, overlap two layers in the direction of water flow, and the two layers are staggered and overlapped to ensure a secure connection.

[0043] (5) Installation of distribution box 4: Install distribution box 4 according to the location specified in the detailed design. Before installation, apply fireproof sealant to the groove at the bottom rear of the box and inside the pre-embedded integrated junction box.
