Description

Technical Field

[0001] This invention relates to a device for emergency sealing and collection of hazardous substances in chemical leaks, belonging to the field of chemical pipeline technology. Background Technology

[0003] Chinese Patent Publication No. (CN 220228321 U) discloses a chemical pipeline leak-sealing device, comprising a base mounted on a movable component, a lower half-ring component mounted on the base, and an upper half-ring component mounted on the lower half-ring component. The upper and lower half-ring components are connected to form a complete ring. A chemical pipeline is disposed within the ring formed by the upper and lower half-ring components. A leak-sealing component is disposed between the upper and lower half-ring components. The leak-sealing component moves along the circumference of the ring to seal the leak point. This invention eliminates the need for manual leak sealing, preventing liquid from the chemical pipeline from splashing onto the human body and ensuring personal safety.

[0004] However, the above-mentioned technology can only temporarily seal the leak. During the sealing process, leaked material will still drip onto the ground and cannot be collected, causing pollution to the surrounding environment.

[0005] Therefore, an emergency sealing and hazardous substance collection device for chemical leaks is proposed. Summary of the Invention

[0006] In view of this, the present invention provides a chemical leak emergency sealing and hazardous substance collection device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of the present invention is implemented as follows: a chemical leak emergency sealing and hazardous substance collection device includes a support frame, a sealing mechanism is provided on the top of the support frame, the sealing mechanism includes a connecting plate, a blocking plate and a telescopic cylinder, the bottom of the connecting plate is fixedly connected to the top of the support frame, the bottom of the blocking plate is movably connected to the inside of the connecting plate, the inner side of the telescopic cylinder is fixedly connected to the outer side of the connecting plate, and the output end of the telescopic cylinder is fixedly connected to the bottom of the blocking plate.

[0008] More preferably, the connecting plate has a sliding groove inside, the bottom of the blocking plate is movably connected to the inside of the sliding groove, and a conveying pipe is fixedly connected to the inner side of the connecting plate.

[0009] More preferably, a rotating rod is movably connected to the right side of the support frame, and the left side of the rotating rod extends through to the left side of the support frame, with a rotating wheel fixedly connected to the left side of the rotating rod.

[0010] More preferably, the surface of the rotating rod is threadedly connected to a collection box, and the bottom of the collection box is movably connected to the support frame.

[0011] More preferably, a rotating motor is fixedly connected to the left side of the support frame, and a rotating wheel is fixedly connected to the output end of the rotating motor. Both the rotating wheel and the rotating wheel are fitted with connecting belts.

[0012] More preferably, a leakage sensor is fixedly connected to the front side of the support frame, and the leakage sensor is electrically connected to the rotating motor and the telescopic cylinder.

[0013] More preferably, a drain pipe is fixedly connected to the front side of the collection box, and a control valve is fixedly connected to the top of the drain pipe.

[0014] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention utilizes a sealing mechanism. When a leak occurs in the conveying pipe, a telescopic cylinder moves a baffle plate downwards, causing the bottom of the baffle plate to insert into the sliding groove, thus blocking and sealing both sides of the conveying pipe to prevent the leak from spreading. By blocking the conveying pipe, it facilitates maintenance of the conveying pipe by personnel and improves the overall emergency sealing efficiency of the equipment.

[0015] II. This invention uses a collection box and a rotating rod. The rotating wheel drives the rotating rod to rotate, and the rotating rod drives the collection box to move. A rotating motor drives the rotating wheel to rotate, and the rotating wheel drives the rotating rod to rotate via a connecting belt, which facilitates operation by the staff. By setting a leak sensor, when a leak occurs in the delivery pipe, the leak sensor controls the rotating motor to rotate, so that the collection box moves to the bottom of the leak point, making it convenient for the staff to collect the leaked material.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 1-5 As shown, this embodiment of the invention provides a chemical leak emergency sealing and hazardous substance collection device, including a support frame 1. A sealing mechanism 2 is provided on the top of the support frame 1. The sealing mechanism 2 includes a connecting plate 201, a baffle plate 202, and a telescopic cylinder 203. The bottom of the connecting plate 201 is fixedly connected to the top of the support frame 1. The bottom of the baffle plate 202 is movably connected to the inside of the connecting plate 201. The inner side of the telescopic cylinder 203 is fixedly connected to the outer side of the connecting plate 201. The output end of the telescopic cylinder 203 is fixedly connected to the bottom of the baffle plate 202. A sliding groove 3 is provided inside the connecting plate 201. The bottom of the baffle plate 202 is movably connected to the inside of the sliding groove 3. A conveying pipe 4 is fixedly connected to the inner side of the connecting plate 201.

[0023] When leakage occurs in the conveying pipe 4, the telescopic cylinder 203 drives the baffle plate 202 to move downward through the sealing mechanism 2, so that the bottom of the baffle plate 202 is inserted into the sliding groove 3 to block and seal both sides of the conveying pipe 4, preventing the leakage from expanding. By blocking the conveying of the conveying pipe 4, it is convenient for staff to maintain the conveying pipe 4 and improve the emergency sealing efficiency of the overall equipment.

[0024] Example 2 like Figure 1-5As shown, in one embodiment, a rotating rod 5 is movably connected to the right side of the support frame 1, and the left side of the rotating rod 5 extends through to the left side of the support frame 1. A rotating wheel 6 is fixedly connected to the left side of the rotating rod 5, and a collection box 7 is threadedly connected to the surface of the rotating rod 5. The bottom of the collection box 7 is movably connected to the support frame 1. A rotating motor 8 is fixedly connected to the left side of the support frame 1, and a rotating wheel 9 is fixedly connected to the output end of the rotating motor 8. A connecting belt 10 is fitted on the surface of both the rotating wheel 9 and the rotating wheel 6. A leakage sensor 11 is fixedly connected to the front side of the support frame 1. The leakage sensor is electrically connected to the rotating motor 8 and the telescopic cylinder 203. A drain pipe 12 is fixedly connected to the front side of the collection box 7, and a control valve 13 is fixedly connected to the top of the drain pipe 12.

[0025] The collection box 7 and the rotating rod 5 are connected by a rotating wheel 6, which drives the rotating rod 5 to rotate. The rotating rod 5 then moves the collection box 7. The rotating motor 8 drives the rotating wheel 9 to rotate, which in turn drives the rotating rod 5 to rotate via a connecting belt 10. This facilitates operation by the staff. By setting a leak sensor 11, when a leak occurs in the delivery pipe 4, the leak sensor 11 controls the rotating motor 8 to rotate, causing the collection box to move to the bottom of the leak point, making it convenient for the staff to collect the leaked material.

[0026] In operation, when a leak occurs in the delivery pipe 4, a leak sensor detects and triggers the leak. The leak sensor then moves the telescopic cylinder 203 downward, which in turn moves the baffle plate 202 downward, causing it to insert into the sliding groove 3 and block the delivery pipe 4. Once the blockage is complete, the leak sensor activates the rotating motor 8, which in turn drives the rotating wheel 9 to rotate. The rotating wheel 9, through the connecting belt 10, drives the rotating wheel 6 to rotate, which in turn drives the rotating rod 5 to rotate. The rotating rod 5 then moves the collection box left and right, bringing it to the bottom of the leak point to collect the leaked material. When there is too much leaked material inside the collection box, the control valve 13 opens the drain pipe 12 to discharge the leaked material, facilitating centralized collection by staff.

[0027] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
