[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] As Figures 1 to 6 shown, this embodiment proposes a leakage detection device for a gas heating pipe network, including an operating table body 1. On both symmetric sides of the upper end face of the operating table body 1, a first baffle 2 is fixedly installed. A sequential feeding component 100 is installed on the tops of the two first baffles 2. On one side of the operating table body 1, support vertical plates 3 are symmetrically installed. A detection water tank 4 is fixedly installed between the two support vertical plates 3. A first U-shaped frame 5 is installed on the tops of the two support vertical plates 3. The operating table body 1 is inclined. A second baffle 6 is fixedly installed on one side of the operating table body 1. Clamping plates 7 are arranged on both symmetric sides of the upper end face of the operating table body 1. A second electric push rod 8 and a second telescopic rod 9 are fixedly installed between the two clamping plates 7 and the first baffle 2. The input end of the second electric push rod 8 is connected to the power supply through an external cable. A moving groove is opened on one side of the two clamping plates 7. An air pump 10 is arranged on one side inside the protective cover 202. The input end of the air pump 10 is connected to the power supply through an external cable. The air outlet end of the air pump 10 is communicated with an air pipe 11. A clamping component 200 is installed at the bottom of the first U-shaped frame 5. A driving component 300 is installed on the two support vertical plates 3;

[0029] The sequential feeding component 100 includes a U-shaped frame two 101 fixedly installed on one side of the top of two baffles one 2. A support base 102 is fixedly installed on one side of the top of the U-shaped frame two 101. An electric push rod one 103 is rotatably connected to the support base 102. The output end of the electric push rod one 103 is fixedly installed with a connecting seat 104. A connecting rod 105 is rotatably connected to the connecting seat 104. An activity groove 106 is formed in the U-shaped frame two 101. The bottom end of the connecting rod 105 penetrates to the bottom of the activity groove 106 and is fixedly installed with a rotating block 107. A fixed rod 108 is fixedly installed inside the U-shaped frame two 101. The rotating block 107 is rotatably connected to the outer surface of the fixed rod 108. Limiting card strips 109 are symmetrically and fixedly installed on both sides of the lower end surface of the U-shaped frame two 101. The same inserting plate 110 is slidably connected inside every two limiting card strips 109. Vertical rods 111 are symmetrically and fixedly installed on the top of the two inserting plates 110. A connecting column 112 is rotatably connected to one side of a plurality of vertical rods 111. Through grooves 113 are formed on both symmetric sides of the rotating block 107. The side wall of the connecting column 112 matches the side wall of the through groove 113. The connecting column 112 is movably connected inside the through groove 113. The limiting card strip 109 matches the side wall of the inserting plate 110;

[0030] By setting the sequential feeding component 100, the heating pipelines can be effectively conveyed sequentially. When it is necessary to convey the heating pipelines sequentially, first, a plurality of heating pipelines are placed between the two clamping plates 7. Then, the electric push rod two 8 is started to drive the two clamping plates 7 to limit the heating pipelines. Then, due to the inclined setting of the operation table body 1, the heating pipelines roll. Then, the electric push rod one 103 is started to drive the rotating block 107 at the bottom of the connecting rod 105 to rotate reciprocally, so as to drive the inserting plates 110 at both ends of the rotating block 107 to move up and down sequentially inside the limiting card strips 109. When one inserting plate 110 is in contact with the operation table body 1, the other inserting plate 110 rises, thereby sequentially driving the heating pipelines.

[0031] Embodiment 2

[0032] As Figures 1 to 6As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that the clamping assembly 200 includes a hydraulic cylinder 201 fixedly installed on the top of the first U-shaped frame 5. The output end of the hydraulic cylinder 201 penetrates through the bottom of the first U-shaped frame 5 and is fixedly installed with a protective cover 202. A first telescopic rod 203 is symmetrically and fixedly installed between the top of the protective cover 202 and the first U-shaped frame 5. A bearing plate 204 is fixedly installed on the lower end surface of the protective cover 202. A first driving motor 205 is fixedly installed inside the protective cover 202. The input end of the first driving motor 205 is connected to a power supply through an external cable. The output end of the first driving motor 205 penetrates through the bearing plate 204 to the bottom through a bearing and is fixedly installed with a movable block 206. Transmission rods 207 are rotatably connected to both ends of the movable block 206. A T-shaped slider 208 is fixedly installed at one end of each of the two transmission rods 207. T-shaped slide rails 209 matching the T-shaped sliders 208 are symmetrically and fixedly installed on both sides of the bottom of the bearing plate 204. A clamping vertical plate 210 is fixedly installed on one side of each of the two T-shaped sliders 208. A pipe sealing plug 211 is fixedly installed on the opposite side of the bottom of the two clamping vertical plates 210. The other end of the air pipe 11 penetrates through one end of the pipe sealing plug 211;

[0033] The clamping assembly 200 provided can automatically seal and clamp both ends of the heating pipe. When it is necessary to automatically seal and clamp both ends of the heating pipe, the first driving motor 205 is started to drive the movable block 206 to rotate. While the movable block 206 is rotating, through the mutual cooperation between the movable block 206, the transmission rod 207, the T-shaped slider 208 and the T-shaped slide rail 209, the pipe sealing plugs 211 on the two clamping vertical plates 210 are driven to move relatively, so as to automatically seal and clamp both ends of the heating pipe.

[0034] The driving assembly 300 includes a protective box 301 fixedly installed on one side of the support vertical plate 3. A second driving motor 302 is fixedly installed inside the protective box 301. The input end of the second driving motor 302 is connected to a power supply through an external cable. Sliding grooves 303 are formed on both support vertical plates 3. Threaded rods 304 are rotatably connected in the two sliding grooves 303. One end of each of the two threaded rods 304 penetrates through the support vertical plate 3 to the outside through a bearing and is fixedly installed with a driving wheel 305. A belt 306 is drivingly connected between the two driving wheels 305. The output end of the second driving motor 302 is fixedly installed at one end of the driving wheel 305. The bottom of the first U-shaped frame 5 is threadedly connected to the outer surface of the threaded rod 304. The bottom of the first U-shaped frame 5 matches the sliding groove 303. The driving assembly 300 provided can effectively drive the clamped heating pipe to perform leakage detection.

[0035] During operation, first place the heating pipeline between the two clamping vertical plates 210, then start the second electric push rod 8 to drive the two clamping plates 7 to limit the heating pipeline. Next, due to the inclined setting of the operation table body 1, the heating pipeline rolls. Then start the first electric push rod 103 to drive the rotating block 107 at the bottom of the connecting rod 105 to rotate reciprocally, thereby driving the plug plates 110 at both ends of the rotating block 107 to move up and down in sequence within the limit clamping strips 109. When one side of the plug plate 110 is in contact with the operation table body 1, the other side of the plug plate 110 rises, thus driving the heating pipeline in sequence. When the heating pipeline rolls to one side of the second baffle 6, then start the second driving motor 302 to drive the driving wheel 305 to rotate. The driving wheel 305 drives another driving wheel 305 to rotate through the belt 306, thereby driving the two threaded rods 304 to rotate. The two threaded rods 304 drive the clamping assembly 200 on the first U-shaped frame 5 to move above the heating pipeline. Then start the hydraulic cylinder 201 to drive the protective cover 202 to move downward close to the heating pipeline. Next, start the first driving motor 205 to drive the movable block 206 to rotate. While the movable block 206 is rotating, through the mutual cooperation between the movable block 206, the transmission rod 207, the T-shaped slider 208, and the T-shaped slide rail 209, the pipe sealing plugs 211 on the two clamping vertical plates 210 are driven to move relatively, thereby clamping and sealing both ends of the heating pipeline. Then continue to move the clamped heating pipeline to above the detection water tank 4 through the driving assembly 300. Next, drive the clamped heating pipeline to extend into the detection water tank 4 filled with water through the hydraulic cylinder 201. Then start the air pump 10 to internally pressurize the heating pipeline. By observing whether there are bubbles emerging in the detection water tank 4, it is judged whether the heating pipeline has leaks. The detected heating pipeline is moved to the next process through the driving assembly 300, realizing integrated operation and reducing labor costs.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
