Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building water supply and drainage, and more specifically, it relates to a protection device for water supply and drainage pipes in civil air defense buildings. Background Art
[0002] In the water supply and drainage pipe system of civil air defense buildings, water leakage is more likely to occur at the bent parts than at the straight parts. This is because:
[0003] First, the bent parts of the pipes need to be connected through elbows or bends and other components that are not continuous with the original pipeline, which will make the connection parts more likely to become loose and aged.
[0004] Second, at the bent parts, the direction of the water flow changes, the flow velocity and pressure fluctuate, and large stress effects are likely to occur at the elbows and connections, resulting in poor sealing or leakage at the interfaces.
[0005] Third, temperature changes will cause the expansion and contraction of the pipes. Due to the complex shape of the bent parts, the influence of thermal expansion and contraction is particularly obvious. If the stress at the connections is not well dispersed, leakage is likely to occur.
[0006] Currently, for the anti-leakage settings at the bent parts of water supply and drainage pipes, a certain protective structure is often added externally to strengthen the connection and increase the difficulty of loosening at the pipe connections. However, this measure can only achieve a preventive effect. When leakage occurs due to pipe damage and deformation, it is difficult to effectively prevent leakage, and the impact of the leaked water flow cannot be effectively buffered and diverted, resulting in the spread of the leakage site and aggravating the destructive impact of the leakage, which is not conducive to subsequent maintenance. Summary of the Invention
[0007] The present invention provides a protection device for water supply and drainage pipes in civil air defense buildings, which solves the technical problems in the related art that it can only prevent leakage and cannot buffer and divert the impact of leaked water flow.
[0008] The present invention provides a protection device for water supply and drainage pipes in civil air defense buildings, including:
[0009] A cover cylinder, in which a receiving cavity is provided, and the entire bent section, part of the first straight section, and part of the second straight section are covered in the receiving cavity;
[0010] A protection module, including a partition board, a traction rod, a plug, a support rod, a damper, and a top rod. A partition board that can close the top of the receiving cavity is slidably arranged in the receiving cavity. A traction rod is fixedly connected below the partition board. A diversion port is opened on the second straight section. A plug that can switch the opening and closing of the diversion port is fixed at the end of the traction rod. A support rod is fixed on the top of the cover cylinder, and a damper is fixed on the support rod. The acting end of the damper is connected to the partition board through a top rod.
[0011] As a further solution of the present invention: the top opening part of the cover cylinder is in a circular ring shape.
[0012] As a further solution of the present invention: springs are symmetrically connected between the inner wall of the top of the cover cylinder and the partition board.
[0013] As a further solution of the present invention: the cover cylinder is provided with a first connection port for plugging and matching with the first DC section and a second connection port for plugging and matching with the second DC section.
[0014] As a further solution of the present invention: a displacement sensor and a signaler are arranged in the cover cylinder, and the displacement sensor is used to detect the change of the displacement amount of the partition board and send the change signal to the background processing through the signaler.
[0015] As a further solution of the present invention: an elastically deformable sealing ring is sleeved on the side wall of the plug.
[0016] The beneficial effect of the present invention lies in:
[0017] The present invention plays a role when leakage occurs at the easily leaked part of the pipeline. The leaked water liquid fills the accommodating cavity. As the liquid level in the accommodating cavity rises and the accommodating cavity is initially filled, the partition board is lifted under the pushing of the water liquid. While expanding the accommodating cavity and above the partition board, the rising of the partition board drives the ejector rod to push upwards, squeezing the damper. Through the action of the damper, the high-speed impact generated by the leaked water flow is buffered, avoiding the continuous action of the impact of the leaked water flow on the leakage part and expanding the leakage range.
[0018] Below the partition board of the present invention, the rising of the partition board drives the traction rod to lift upwards, driving the plug to move upwards to open the diversion port, so that the leaked water liquid in the accommodating cavity is re-guided back into the pipeline through the diversion port, enabling the pipeline to still maintain normal diversion during the waiting time for maintenance after leakage occurs.
[0019] When water liquid leakage occurs in the present invention and the partition board is pushed to rise, the displacement sensor detects the position change of the partition board, transmits the displacement signal to the signaler and sends it to the background. The supervisors in the background can detect it in real time and make a leakage judgment, immediately giving corresponding flashing and beeping alarm reminders, and notifying professional personnel to go to the leaking pipeline for repair.

Detailed implementation manners
[0026] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.
[0027] Embodiment
[0028] Figure 2 It shows the pipeline layout situation where the actual drainage pipeline needs to be bent due to factors such as elevation difference and building surface obstruction. Among them, the pipeline is divided into a first straight - flow section, a bent section, and a second straight - flow section. There is an elevation difference between the first straight - flow section and the second straight - flow section, and it is transitioned through the bent section. The two end parts of the bent section are prone to leakage points.
[0029] Regarding the protection treatment for the above - mentioned prone - to - leakage points, refer to Figures 1 to 5 As shown, the present invention discloses a protection device for water supply and drainage pipes in civil air defense buildings, including:
[0030] A hood cylinder 10, an accommodation cavity 100 is arranged inside the hood cylinder 10, and the entire bent section, part of the first straight - flow section, and part of the second straight - flow section are covered in the accommodation cavity 100;
[0031] The protection module 20 includes a partition plate 201, a towing rod 202, a plug 203, a support rod 204, a damper 205 and a push rod 206. A partition plate 201 that can seal the top of the accommodation cavity 100 is slidably arranged in the accommodation cavity 100. A towing rod 202 is fixedly connected below the partition plate 201. A diversion port is opened on the second DC section. A plug 203 detachably matched with the diversion port is fixed on the end of the towing rod 202. A support rod 204 is fixed on the top of the cover cylinder 10. A damper 205 is fixed on the support rod 204. The acting end of the damper 205 is connected with the partition plate 201 through a push rod 206.
[0032] The present invention plays a role when leakage occurs at the easily leaked part of the pipeline. Specifically, the leaked water liquid fills into the accommodation cavity 100. As the liquid level in the accommodation cavity 100 rises and the accommodation cavity 100 is initially filled, the partition plate 201 is lifted under the extrusion of the water liquid, expanding the accommodation cavity 100 and simultaneously generating post-leakage treatment operations on both sides respectively:
[0033] On the upper side of the partition plate 201, the rising of the partition plate 201 drives the push rod 206 to push upwards, squeezing the damper 205, and buffering the high-speed impact generated by the leaked water flow through the action of the damper 205, avoiding the continuous action of the impact of the leaked water flow on the leakage part and expanding the leakage range;
[0034] On the lower side of the partition plate 201, the rising of the partition plate 201 drives the towing rod 202 to lift upwards, driving the plug 203 to move upwards to open the diversion port, so that the leaked water liquid in the accommodation cavity 100 is re-directed back into the pipeline through the diversion port, enabling the pipeline to still maintain normal diversion during the waiting time for maintenance after leakage occurs.
[0035] The top opening part of the cover cylinder 10 is in a circular ring shape.
[0036] While ensuring that the up and down movement of the push rod 206 is unobstructed, it plays a limiting role in the rising of the partition plate 201.
[0037] Springs 210 are symmetrically connected between the inner wall of the top of the cover cylinder 10 and the partition plate 201.
[0038] The setting of the springs 210, on the one hand, provides a certain degree of supplement to the buffering effect of the damper 205 on the leaked water flow through its elastic expansion and contraction, and on the other hand, keeps the partition plate 201 in a suspended state when it is not squeezed by the water flow.
[0039] The cover cylinder 10 is provided with a first connection port 101 for plugging and matching with the first DC section and a second connection port 102 for plugging and matching with the second DC section.
[0040] A displacement sensor 30 and a signaler 300 are provided in the cover cylinder 10. The displacement sensor 30 is used to detect the change in the displacement of the partition plate 201 and send the change signal to the background processing through the signaler 300.
[0041] When water leakage occurs and the partition plate 201 is pushed up, the displacement sensor 30 detects the position change of the partition plate 201, transmits the displacement signal to the signaler 300 and sends it to the background. The supervisors in the background can detect it in real time and make a leakage judgment, immediately give corresponding flash and buzzer alarm reminders, and notify the professionals to go to the leaking pipeline for repair.
[0042] An elastically deformable sealing ring 2030 is sleeved on the side wall of the plug 203.
[0043] When the plug 203 is pressed into the diversion port, the sealing ring 2030 automatically expands outwards to keep close fit with the diversion port.
[0044] The embodiments of the present invention have been described above, but the embodiments are not limited to the above specific implementation manners. The above specific implementation manners are only illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make more equivalent embodiments in various forms, all of which fall within the protection scope of this embodiment.
