Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline safety covers, specifically a leak-proof chemical pipeline safety cover. Background Technology
[0002] Chemical pipelines refer to pipelines that transport chemical raw materials. They are mainly made of steel or alloys and have good wear resistance and corrosion resistance, so they are widely used in various fields. However, existing chemical pipelines are prone to leakage and spread of media due to loose installation or aging of connections over a long period of use, which can affect the surrounding environment. Furthermore, minor leaks cannot be detected in a timely and effective manner. Therefore, leak-proof chemical pipeline safety covers are installed, with leak detection mechanisms on the cover to determine the leakage situation.
[0003] However, since the current safety shields are connected using bolts, the efficiency of disassembly and repair is low when a leak occurs. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a safety cover for leak-proof chemical pipelines, which solves the problems mentioned in the background.
[0005] This utility model provides the following technical solution: a safety cover for a leak-proof chemical pipeline, including a conveying pipeline, an upper cover body is provided above the conveying pipeline, and a lower cover body is provided directly below the upper cover body. A fastening mechanism is provided on the outer side of the upper cover body outside the lower cover body. The fastening mechanism includes: an upper buckle block, a strap, and a rotating seat. A slot is provided on the upper surface of the upper buckle block. A D-ring buckle is installed on the upper side of the rotating seat above the side surface of the lower cover body. A rotating shaft is installed inside the rotating seat. A ratchet gear is installed on the outer side of one end of the rotating shaft. A limit pawl is installed on one side of the ratchet gear on the side surface of the rotating seat.
[0006] As a further embodiment of this utility model: a gasket mechanism is provided between the upper cover and the lower cover, the gasket mechanism including: a pipe gasket and a cover gasket.
[0007] As a further improvement of this utility model, an alarm mechanism is installed on the upper surface of the upper cover.
[0008] As a further improvement of this utility model: the upper end of the strap is installed with a limit stop inside the slot, and the slot is fixedly connected to the upper cover.
[0009] As a further improvement of this utility model: the rotating seat is fixedly connected to the lower cover, and a strap buckle is installed on the outside of the slot.
[0010] As a further embodiment of this utility model: the pipe gasket is fixedly connected to the cover gasket, and the gasket mechanism is a flexible rubber component.
[0011] As a further improvement of this utility model, the ratchet gear engages with the limiting ratchet pawl.
[0012] As a further improvement of this utility model, the alarm mechanism is configured to penetrate the upper cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The ratchet and pawl are designed for unidirectional limiting. The entire strap is wound around the shaft, thereby clamping the pipe gasket and cover gasket between the lower and upper covers. This ensures a tight clamping. The limiting and fixing method of the fastening mechanism allows for quick disassembly, facilitating rapid repairs in case of leakage. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0022] like Figure 1-5 As shown, this embodiment provides a leak-proof safety cover for a chemical pipeline, including a conveying pipeline 1. An upper cover 2 is disposed above the conveying pipeline 1, and a lower cover 3 is disposed directly below the upper cover 2. A fastening mechanism 5 is disposed on the outer side of the lower cover 3 of the upper cover 2. The fastening mechanism 5 includes: an upper buckle 501, a strap 503, and a rotating seat 505. A slot 502 is formed on the upper surface of the upper buckle 501. A limit stop is installed at the upper end of the strap 503 inside the slot 502. 02 is fixedly connected to the upper cover 2. A D-ring buckle 504 is installed on the side surface of the lower cover 3 above the rotating seat 505. A rotating shaft 506 is installed inside the rotating seat 505. The rotating seat 505 is fixedly connected to the lower cover 3. A strap buckle is installed on the outside of the slot 502. A ratchet 507 is installed on the outside of one end of the rotating shaft 506. A limiting pawl 508 is installed on one side of the ratchet 507 on the side surface of the rotating seat 505. The ratchet 507 and the limiting pawl 508 are engaged and locked.
[0023] like Figure 2-3 As shown, in this embodiment, a gasket mechanism 6 is provided between the upper cover 2 and the lower cover 3. The gasket mechanism 6 includes: a pipe gasket 601 and a cover gasket 602. The pipe gasket 601 and the cover gasket 602 are fixedly connected. The gasket mechanism 6 is a flexible rubber component. An alarm mechanism 4 is installed on the upper surface of the upper cover 2. The alarm mechanism 4 is connected to the upper cover 2.
[0024] The working principle of this utility model is as follows: During use and installation, the pipe gaskets 601 at both ends of the gasket mechanism 6 are respectively inserted into the joint positions of the flanges of the two conveying pipes 1. After the flanges at the ends of the conveying pipes 1 are engaged and fixed with bolts, the lower cover 3 is positioned below the cover gasket 602, and the upper cover 2 is positioned above the cover gasket 602. The limiting block at the upper end of the strap 503 is inserted into the slot 502 at the upper end of the upper buckle 501. The strap 503 is then inserted through the inside of the D-ring buckle 504. One end of the strap 503 is passed through the strap buckle on the rotating shaft 506. The rotating shaft 506 is then rotated... The internal rotation of the moving seat 505, with the ratchet 507 and the limiting pawl 508 providing unidirectional limiting, ensures a tight clamping of the upper cover 2 and the lower cover 3. The binding strap 503 is wound around the entire structure using the rotating shaft 506, thereby clamping the pipe gasket 601 and the cover gasket 602 onto the lower cover 3 and the upper cover 2 as a whole, thus achieving the binding of the flange joint position of the conveying pipe 1. The alarm mechanism 4 set on the upper cover 2 can be used for detection and handling during daily use. When a leak occurs at the joint position of the conveying pipe 1, it can be quickly identified. Therefore, the upper cover 2 and the lower cover 3 are fixed by the limiting method of the fastening mechanism 5, which can achieve the purpose of quick disassembly and facilitate rapid repair after a leak occurs.
