Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a baffle structure for confined spaces. Background Technology

[0002] As a sealing device for specific scenarios, confined space blocking structures are widely used in drainage systems and narrow cavities of various mechanical equipment. They are primarily used to isolate different spatial areas, prevent media leakage, or facilitate maintenance and repair. In practical applications, confined space blocking structures typically require the following structures:

[0003] 1. As the main path for fluid flow, drainage channels need to have a certain strength and corrosion resistance;

[0004] 2. Drain pipes connect to the drainage system and guide fluid flow; their connection to the drainage system must be airtight.

[0005] 3. The sealing mechanism is used to seal the sewer channels and is the core part of the entire structure;

[0006] 4. The positioning rod and positioning block work together to limit the movement direction of the sealing block and ensure the accuracy of the sealing operation.

[0007] Currently, manufacturers employ various equipment and methods to effectively seal confined spaces. Some manufacturers use simple flat sealing plates, fixed with bolts, etc. This method is simple in structure, but installation and disassembly are difficult in confined spaces. Other manufacturers use expandable sealing plates, which expand by inflating with air or liquid to achieve sealing. This method has a better sealing effect, but requires high-quality sealing plate materials and an expansion mechanism. Some manufacturers have introduced mechanical sealing plates, using screws, gears, and other mechanical structures to move and seal the sealing plate.

[0008] However, the above-described implementation methods still have the following problems. Regarding sealing stability, some sealing plate structures are prone to loosening or displacement after long-term use or when subjected to fluid impact, resulting in poor sealing performance. Regarding ease of installation and disassembly, many sealing plate structures are difficult to operate in confined spaces due to their complex design or large size, increasing construction difficulty and time costs. This application proposes a solution to this problem: a sealing plate structure designed for confined spaces. This structure improves the stability of the sealing block after sealing through designs such as the threaded engagement between the lead screw and the sealing block, the sliding engagement between the positioning rod and the positioning block, and the fitting insertion of the sealing plate into the groove. Simultaneously, structures such as locking blocks and elastic plates enhance the ease of installation, disassembly, and replacement of the sealing block. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a blocking plate structure for confined spaces. This solves the problem that some blocking plate structures are prone to loosening or displacement during long-term use or when subjected to fluid impact, resulting in poor sealing performance. In terms of ease of installation and disassembly, many blocking plate structures are difficult to operate in confined spaces due to their complex design or large size, which increases the difficulty of construction and time costs.

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

[0011] A blockage structure for a confined space includes a drainage channel, a drainage pipe fixed to the left surface of the drainage channel, and a blocking mechanism on the right side of the drainage pipe. The blocking mechanism includes a lead screw and two blocking blocks, which are threaded together. A receiving pipe is embedded in the drainage channel, and two positioning rods are fixedly connected between the receiving pipe and the drainage channel. Two positioning blocks are movably engaged with the surfaces of the two blocking blocks, and the two positioning blocks are movably connected to the two positioning rods respectively. A turntable is fixedly installed at the right end of the lead screw, and the other end is rotatably connected to a support mechanism inside the drainage pipe. A fastening plate is fixedly connected to the right surface of the drainage channel, and a set of fastening bolts is installed inside the fastening plate.

[0012] Preferably, both outer walls of the two sealing blocks are provided with connection holes, and both connection holes are equipped with connecting bolts. Both sealing blocks are movably connected to the receiving pipe. Both outer walls of the two sealing blocks are provided with grooves. The support mechanism includes a support plate and support rods fixed at both ends of the support plate. Both support rods are fixedly connected to the inner wall of the drain pipe. Bearings are provided in the support plate, and the lead screw is rotatably inserted into the support plate through the bearings.

[0013] Preferably, a sealing plate is fixedly installed on the side wall of the support plate, and the sealing plate is movably engaged with the groove. An arc-shaped groove is opened on the opposite back of the two positioning blocks, and the two arc-shaped grooves are movably connected to the two positioning rods respectively. Two telescopic grooves are opened on the opposite surface of the positioning blocks, and a locking block is movably engaged in the two pairs of telescopic grooves. The two pairs of locking blocks abut against the two ends of the two sealing blocks respectively. An elastic plate is fixedly connected between the two pairs of telescopic grooves and the two pairs of locking blocks.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When sealing the sewer pipe, the knob drives the screw to rotate, and during the rotation, the sealing block slides between the two positioning rods to seal the sewer pipe. The screw drives the sealing block to move and position, which facilitates sealing the sewer pipe from the outside and improves the stability of the sealing block after sealing.

[0016] 2. When the sealing block wears out after prolonged use, the clamping block is squeezed from the side wall of the positioning block and retracts into the telescopic groove, and the sealing block slides out from between the two positioning blocks. After sliding, the connecting bolts are unscrewed to separate the two sealing blocks from the screw. After replacing the sealing block, the two sealing blocks are fixed on the screw with the connecting bolts. After fixing, the sealing block is engaged with the positioning block. The elastic plate in the telescopic groove of the side wall of the positioning block pushes the clamping block to engage with both ends of the sealing block, which improves the convenience of installing, disassembling and replacing the sealing block.

Detailed Implementation

[0024] This application provides a blocking plate structure for confined spaces, effectively solving the problem that some blocking plate structures are prone to loosening and displacement after long-term use or when subjected to fluid impact, resulting in poor sealing effect. In terms of ease of installation and disassembly, many blocking plate structures are difficult to operate in confined spaces due to their complex design or large size, increasing construction difficulty and time costs. This structure improves the stability of the blocking block after sealing through the threaded engagement of the lead screw and the blocking block, the sliding engagement of the positioning rod and the positioning block, and the fitting insertion of the sealing plate and the groove. At the same time, the use of locking blocks, elastic plates and other structures improves the convenience of installing, disassembling and replacing the blocking block. Example

[0025] like Figures 1 to 5 As shown, the technical solution in this application embodiment effectively solves the problems that some blocking plate structures are prone to loosening and displacement after long-term use or when subjected to fluid impact, resulting in poor sealing effect. Regarding ease of installation and disassembly, many blocking plate structures are difficult to operate in confined spaces due to their complex design or large size, increasing construction difficulty and time costs. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a blocking structure for confined spaces, including a drain channel 1, a drain pipe 2 fixed to the left surface of the drain channel 1, and a blocking mechanism on the right side of the drain pipe 2. The blocking mechanism includes a lead screw 9 and two blocking blocks 10, which are threadedly connected. A receiving tube 11 is embedded and fixed in the drain channel 1, and two positioning rods 3 are fixedly connected between the receiving tube 11 and the drain channel 1. Two positioning blocks 7 are movably engaged on the surfaces of the two blocking blocks 10, and the two positioning blocks 7 are respectively engaged with two positioning rods 3. Positioning rod 3 is movably connected. The right end of screw 9 is fixedly installed with turntable 5 and the other end is rotatably connected to the support mechanism inside the drain pipe 2. The right surface of drain channel 1 is fixedly connected with fastening plate 4. A set of fastening bolts 6 are installed in fastening plate 4. Hold the knob to drive screw 9 to rotate. During the rotation, the sealing block 10 slides between the two positioning rods 3 to seal the drain pipe 2. The screw 9 drives the sealing block 10 to move and position. After sealing, the sealing plate 14 on the side wall of support plate 16 fits into the groove 8 to keep the side wall of sealing block 10 sealed.

[0027] Both sides of the outer wall of the two sealing blocks 10 are provided with connecting holes 12, and connecting bolts 13 are installed in both connecting holes 12.

A spring plate 18 is fixedly connected between each pair of telescopic grooves 20 and the two pairs of locking blocks 17. When the blocking blocks 10 wear out after prolonged use, the locking blocks 17 are squeezed from the side wall of the positioning block 7 and retracted into the telescopic groove 20, causing the blocking blocks 10 to slide out between the two positioning blocks 7. After sliding, the connecting bolt 13 is unscrewed to separate the two blocking blocks 10 from the lead screw 9. After replacing the blocking blocks 10, the two blocking blocks 10 are fixed to the lead screw 9 using the connecting bolt 13, and after fixing, the blocking blocks 10 are engaged with the positioning blocks 7. The spring plate 18 in the telescopic groove 20 on the side wall of the positioning block 7 pushes the locking blocks 17 to engage with both ends of the blocking blocks 10, improving the convenience of installing, disassembling, and replacing the blocking blocks 10.
