[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] See also Figures 1 to 5 As shown, the utility model is a natural gas pipeline accumulated liquid cleaning device, comprising a pipeline body 1 and a liquid storage tank 2 arranged on one side of the bottom thereof, a bracket 101 and a cover plate 102 are sleeved on the bottom and top of the outer wall of the pipeline body 1, the rear end faces of the bracket 101 and the cover plate 102 are movably connected by hinges, a T-shaped slot 1012 is provided on one side of the front end of the upper surface of the bracket 101, a pressing plate 106 is arranged on the upper part of the cover plate 102, an adjusting spring 105 is arranged on the top of the pressing plate 106, and a mounting assembly 3 is arranged inside the T-shaped slot 1012, and the position of the pressing plate 106 can be adjusted under the elastic performance of the adjusting spring 105, so as to make corresponding adjustments according to the size of the pipeline body 1;

[0032] The mounting assembly 3 includes a push plate 301 and a clamping plate 302 fixed at the top center position thereof. A connecting rod 303 is fixedly connected to the bottom of the outer wall of one side of the clamping plate 302. The other end of the connecting rod 303 passes through a through hole on an end surface of one side of the fixing plate 305 and is connected to a limiting plate 306. The clamping plate 302 and the limiting plate 306 are connected by the connecting rod 303 to play a role of connecting transmission. The cross section of the clamping plate 302 is L-shaped.

[0033] The outer sides of the T-shaped slot 1012 are provided with sliding grooves 1011 at both ends. The top center of the pressing plate 106 is fixedly connected with a connecting rod 104. The top end of the connecting rod 104 passes through the through hole at the top of the inner wall of the cover plate 102 and is connected to the baffle plate 103. The pressing plate 106 and the baffle plate 103 are connected by the connecting rod 104, which plays a role of connecting transmission.

[0034] The adjusting spring 105 is sleeved on the outer side of the outer wall of the linkage rod 104 , and the adjusting spring 105 is located between the inner wall of the cover plate 102 and the top of the pressure plate 106 ;

[0035] A connecting pipe 201 is provided on one side of the top of the liquid storage tank 2, and the top of the connecting pipe 201 passes through the bottom center of the bracket 101 and the bottom outer wall of the pipeline body 1. A drain pipe 202 is provided on one side of the bottom of the liquid storage tank 2. The liquid storage tank 2, the connecting pipe 201, the drain pipe 202, etc. are all prior arts, so they will not be described in detail here.

[0036] The front and rear edges of the top of the push plate 301 are fixedly connected with a slide plate 3011, and the top of the slide plate 3011 is located inside the slide groove 1011. The push plate 301 is moved and limited with the assistance of the slide plate 3011 and the slide groove 1011.

[0037] A compression spring 304 is sleeved on the outer side of the outer wall of the connecting rod 303. The compression spring 304 is located between the clamping plate 302 and the fixing plate 305. The outer wall of the fixing plate 305 is fixed on the inner wall of the T-slot 1012. The elastic performance of the compression spring 304 drives the clamping plate 302 to move.

[0038] When the above arrangement is in use, the connecting pipe 201 in the bracket 101 is first inserted into the interior of the pipe body 1, and then the cover plate 102 is rotated under the action of the hinge. During the rotation of the cover plate 102, the pressure plate 106 inside it will contact the outer wall of the top of the pipe body 1, and the pressure plate 106 will move upward, and the top of the pressure plate 106 is connected to the baffle 103 through the connecting rod 104. Therefore, when the pressure plate 106 moves upward, the baffle 103 will be driven to move under the action of the connecting rod 104, and the adjusting spring 105 will be squeezed. Under the action of the elastic performance of the adjusting spring 105, a reverse force will be applied to the pressure plate 106, and the pressure plate 106 will be pressed tightly against the outside of the pipe body 1, so that corresponding adjustments can be made according to the size of the pipe body 1. It has a wide range of applications and is suitable for use in After the cover plate 102 covers the surface of the bracket 101, the push plate 301 is pushed to one side. The push plate 301 is subjected to force and drives the card plate 302 to slide with the assistance of the slide plate 3011 and the slide groove 1011. The inner wall of the card plate 302 is connected to the limit plate 306 through the connecting rod 303. Therefore, when the card plate 302 moves, the limit plate 306 will be driven to move under the action of the connecting rod 303, and the compression spring 304 will be squeezed. Then the top end of the card plate 302 is inserted into the through hole at the bottom of the cover plate 102. Since the cross-section of the card plate 302 is L-shaped, it can limit the cover plate 102, and the installation is completed. The same is true for disassembly, which makes it convenient for the staff to quickly disassemble and assemble the bracket 101, the cover plate 102, the liquid storage tank 2, etc., saving time and improving work efficiency.

[0039] Among them Figure 2 , 6As shown, a sealing assembly 4 is provided on one side of the interior of the liquid storage tank 2. The sealing assembly 4 includes a cylindrical frame 401 and a floating ball 404 placed therein. A sealing ring 405 is bonded to the outer edge of the bottom of the cylindrical frame 401. The sealing ring 405 can further increase the sealing performance.

[0040] The top of the outer wall of the cylindrical frame 401 is evenly spaced and fixedly connected with side plates 4011 along the circumferential direction, and a telescopic rod 402 is installed at the bottom center of the side plate 4011. A tension spring 403 is sleeved on the outer side of the outer wall of the telescopic rod 402, and the telescopic rod 402 plays a role of limiting the tension spring 403;

[0041] When the above arrangement is in use, the accumulated liquid inside the pipeline body 1 will enter the liquid storage tank 2 through the connecting pipe 201. As the liquid inside the liquid storage tank 2 increases, the buoyancy of the float 404 increases, so that it will move upward and drive the outer cylindrical frame 401 to move upward. The upward movement of the cylindrical frame 401 will drive the telescopic rod 402 to extend through the upper side plate 4011 of the outer wall, and stretch the tension spring 403. The sealing effect of the sealing ring 405 on the bottom plate of the cylindrical frame 401 on the outer side of the discharge pipe 202 disappears. At this time, the liquid inside the liquid storage tank 2 The liquid can be discharged from the drain pipe 202. When the liquid inside the liquid storage tank 2 gradually decreases, the buoyancy of the float 404 is reduced, and the buoyancy is less than the tension of the tension spring 403. At this time, the elastic performance of the tension spring 403 pulls the cylindrical frame 401 downward, and makes its bottom end and the sealing ring 405 seal the port of the drain pipe 202 again, thereby ensuring that there is a certain amount of liquid inside the liquid storage tank 2, and at the same time, the drain port can be sealed to avoid natural gas leakage when the liquid inside is discharged.

[0042] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
