[0002] With the continuous improvement of the national industrial system, my country's infrastructure construction has gradually gained attention and investment has increased. In engineering operations, choke manifolds mainly implement well control operations through choke valves, while well control manifolds can take corresponding solutions when the well is in danger.

[0003] A search revealed Chinese patent CN214576878U, which discloses an integrated choke and kill manifold, comprising a choke manifold, a second manifold, and a bottom connector. The second manifold is located on one side of the choke manifold, and a bottom connector is located at the top of the choke manifold. Both the choke manifold and the second manifold have stabilizing structures at their bottom ends. An encasing structure is provided between the choke manifold and the second manifold. Both the choke manifold and the second manifold have explosion-proof structures inside, including buffer blocks, pressure-reducing blocks, and pressure-reducing pipes. The buffer blocks are all located inside the choke manifold and the stabilizing structure, and pressure-reducing blocks are fixed to the bottom ends of each buffer block. This invention, by incorporating explosion-proof structures, achieves the function of preventing damage to the choke and kill manifold. When using the device, the fixing blocks maintain the stability of each pipe under the support of the support plate, and the support plate is connected into a whole by connecting rods under the fixation of the support columns, thereby improving the stability of the device.

[0017] Example 1 like Figure 1-3 As shown, this invention provides an integral throttling and kill manifold, including a manifold body 1. The outer wall of the manifold body 1 is provided with a heat insulation device, which includes a symmetrically arranged protective cover 2 and a protective cover 3. A fixing plate 4 is fixedly installed on both outer walls of the protective cover 2, and a fixing plate 5 is fixedly installed on both outer walls of the protective cover 3. In this embodiment, a magnet 6 is provided at the bottom of the fixing plate 4, and a magnet 7 is fixedly installed at the top of the fixing plate 5. The magnet 6 and magnet 7 are magnetically connected to each other. A fixing rod 8 is fixedly installed at the top of the fixing plate 5, and the fixing rod 8 passes through a through hole provided on the fixing plate 4. The interior of protective cover 1 2 and protective cover 2 3 is filled with heat insulation material. A cleaning device is also provided on the outside of the pipe of the manifold body 1. The cleaning device includes a collar 9, which is sleeved on the outer wall of the manifold body 1. A connecting rod 10 is provided on the outer wall of the collar 9. An installation plate 11 is fixedly installed on one end of the connecting rod 10. A moving rod 13 is movably provided through the middle of the installation plate 11. A brush 14 is provided on the outside of the moving rod 13. A handle 12 is provided on the outward end of the moving rod.

[0018] In this embodiment, an anti-slip pad is fitted on the outer wall of the handle 12.

[0019] The working principle and beneficial effects of the above technical solution are as follows: In use, the protective covers 1-2 and 2-3 prevent the inside of the manifold 1 from freezing, making it less susceptible to damage due to low temperatures. The magnets 1-6 and 2-7 allow for quick installation and removal of the protective covers 1-2 and 2-3 from the manifold 1. The fixing rod 8 passes through the fixing plate 1-4, preventing the protective covers 1-2 and 2-3 from becoming misaligned. The handle 12 moves the connecting rod 10, and the brush 14 on the moving rod 13 unclogs the inside of the manifold 1.

[0020] Example 2 like Figure 4-5 As shown, based on Embodiment 1, in this embodiment, the cleaning device further includes two slides 16, with two semi-arc connecting plates 17 arranged on the inner sidewalls of the slides 16. The two slides 16 are symmetrically arranged on both sides of the pipe end of the manifold body 1, and the two oppositely arranged connecting plates 17 are fastened together with bolts. A plurality of sliders 18 are arranged inside the collar 9, and the sliders 18 slide within the slides 16. In this embodiment, the collar 9 is an arc-shaped block, and two are provided.

[0021] In order to make the slide rail fit more closely to the outer wall of the pipe of the manifold body 1, in this embodiment, a rubber pad 15 is provided on the inner side wall of the slide rail 16.

[0022] In this embodiment, the brush 14 includes a sleeve 14-1, which is fitted onto the connecting rod 13 and threadedly connected to it. A plurality of support rods 14-2 are evenly distributed on the outer side of the sleeve 14-1. A connector 14-3 is provided at the bottom of each support rod 14-2, and the lower end of the connector 14-3 is hinged to the inward-facing end of the sleeve 14-1. Each support rod 14-2 includes an upper rod 14-21 and a lower rod 14-22. The lower rod 14-22 is rotatably mounted on the upper end of the connector 14-3, and a toothed ring 1 is provided on the outer side of the bottom of the lower rod 14-22. 4-4, A limiting ring 14-5 is provided across the outer side of the gear ring 14-4. A straight toothed pull bar 14-6 is inserted into the limiting ring 14-5. The straight toothed pull bar 14-6 meshes with the gear ring 14-4. A pull ring 14-7 is provided on the outward side of the straight toothed pull bar 14-6. The upper rod 14-21 and the lower rod 14-22 are hinged together, and a spring piece 14-8 is provided between the upper rod 14-21 and the lower rod 14-22. The spring piece 14-8 keeps the upper rod 14-21 away from the connecting rod 13. Brush bristles 14-9 are provided on the outer side of both the upper rod 14-21 and the lower rod 14-22.

[0023] The working principle and beneficial effects of the above technical solution are as follows: In use, first, install the two slide rails onto the outer wall of the manifold body 1 via the mating of the two connecting plates 17. Then, place the collar 9 onto the slide rails. During installation, keep the connecting rod 13 in its outermost position. After installation, the inner end of the connecting rod should be at the port of the manifold body 1. If only the pipe parallel to the connecting rod needs cleaning, there is no need to install the straight toothed strip 14-6. Simply insert the connecting rod into the pipe and pull it back and forth to rotate it axially to clean the inner wall of the pipe. When cleaning is required for the longitudinal pipeline connected to the rear of the pipeline, after the connecting rod 13 continues to extend into the pipeline, when it reaches the longitudinal pipeline, it continues to move forward until the support rod 14-2 is completely separated from the transversely arranged pipeline. Under the action of the spring piece 14-8, the upper rod 14-21 springs outward, and then the connecting rod 13 is pulled backward. The upper rod 14-21 is engaged in the longitudinal pipeline. As the connecting rod 13 moves backward, the support rod 14-2 unfolds, and then the straight toothed pull strip 14-6 is inserted into the limiting ring 14-5 so that it meshes with the toothed ring 14-4. To facilitate the installation of the straight toothed pull strip 14-6, a guide line can be tied to the inward end of the straight toothed pull strip 14-6. After the guide line passes around the limiting ring 14-5, it is folded back and extends out of the pipeline. During installation, the guide line is pulled to install. After installation, pull the straight toothed rod 14-6 back and forth to rotate the support rod 14-2, thus cleaning the longitudinal pipeline. After cleaning, simply pull the connecting rod backward to remove it.

[0024] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
