[0016] The present invention is described in detail below in conjunction with embodiments, but the present invention is not limited to these embodiments.

[0017] The embodiment of the present invention provides a gas storage reservoir sealant automatic application device, such as Figures 1 to 10 As shown, the device comprises: A moving mechanism, which has a cavity for accommodating the sealant, and the moving mechanism can move along the center line 9 of the gas storage reservoir; A rotating conveying mechanism, one end of which is connected to the cavity; The glue discharging mechanism is connected to the end of the rotating conveying mechanism away from the cavity; the rotating conveying mechanism is used to drive the glue discharging mechanism to rotate with the center line 9 of the gas storage reservoir as the central axis, and to convey the sealant to the glue discharging mechanism; the glue discharging mechanism is used to apply the sealant on the inner wall of the lining 10 of the gas storage reservoir; The glue dispensing mechanism comprises a first-sequence glue dispensing head 1 and a second-sequence glue dispensing head 2. The first-sequence glue dispensing head 1 and the second-sequence glue dispensing head 2 are constructed in a skip-bin interval. Convex slopes are formed on both sides of the first-sequence glue layer applied by the first-sequence glue dispensing head 1, and concave slopes are formed on both sides of the second-sequence glue layer applied by the second-sequence glue dispensing head 2. Adjacent convex slopes and concave slopes form a pressure slope joint.

[0018] Furthermore, the moving mechanism comprises: Track 7, laid at the bottom of the inner wall of the lining 10 of the gas storage reservoir, the track 7 is formed by connecting multiple sections of guide rails in sequence, and the multiple sections of guide rails are detachably connected; The glue machine 8 is arranged on the track 7 and can move along the center line 9 of the gas storage reservoir; the glue machine 8 has a cavity inside, and the cavity is filled with sealant; the vertical distance between the first-order glue head 1 and the glue machine 8 is greater than the length of each section of the guide rail.

[0019] In practical applications, reference Figure 2 As shown, two tracks 7 can be set at the bottom of the lining 10 of the circular gas storage to ensure that the glue machine 8 moves along the center line 9 of the gas storage. The track 7 is connected by multiple sections of guide rails, and the length S2 of each section of the guide rail is less than the distance S1 between the first-order glue head 1 and the glue machine 8. After the glue machine 8 passes a section of the guide rail, this section of the guide rail can be removed. The purpose of this arrangement is to ensure that the first-order glue head 1 can rotate along the circumference of the gas storage, so that the sealant can be scraped and coated on the concrete surface of all the linings 10 around the gas storage.

[0020] In an embodiment of the present invention, the rotary conveying mechanism comprises: An L-shaped glue supply hose, one end of which is connected to the cavity, and the other end of which is connected to the first-order glue outlet 1 and the second-order glue outlet 2 through a glue guide hose 3; The driving member is connected to the L-shaped rubber supply hose and is used to drive the L-shaped rubber supply hose to rotate around the center line 9 of the gas storage reservoir to drive the first-order rubber outlet head 1 and the second-order rubber outlet head 2 to rotate.

[0021] The L-shaped rubber supply hose includes a horizontal pipe section 6 and a vertical pipe section 5 .

[0022] The horizontal pipe section 6 of the L-shaped glue supply hose is connected to the glue machine 8, and its length should be greater than the distance S1 between the first-order glue head 1 and the glue machine 8, and its position should be on the center line 9 of the circular gas storage reservoir. The vertical pipe section 5 is connected to the end of the horizontal pipe section 6 away from the glue machine 8, and the vertical pipe section 5 is respectively connected to the first-order glue head 1 and the second-order glue head 2 through the glue guide pipe 3. The driving member drives the L-shaped glue supply hose to rotate around the center line 9 of the gas storage reservoir to drive the first-order glue head 1 and the second-order glue head 2 to rotate. This setting can ensure that the first-order glue head 1 and the second-order glue head 2 rotate 360° in the radial direction of the gas storage reservoir with the center line 9 of the circular gas storage reservoir as the central axis, so as to scrape the sealing layer on the surface of the lining 10 of the gas storage reservoir.

[0023] Furthermore, the rotating conveying mechanism also includes: a rotating joint 4, which is arranged at the end of the L-shaped glue supply hose away from the cavity, and the first-sequence glue head 1 and the second-sequence glue head 2 are connected to the rotating joint 4 through the glue guide hose 3; the first-sequence glue head 1 and the second-sequence glue head 2 can rotate in the horizontal direction through the rotating joint 4.

[0024] A rotating joint 4 is arranged at the end of the L-shaped glue supply pipe away from the cavity, and a glue guide pipe 3 is arranged on the rotating joint 4. The purpose of this arrangement is to ensure that the glue guide pipe 3 and the first-order glue outlet head 1 and the second-order glue outlet head 2 can rotate arbitrarily in the horizontal direction, so as to ensure that the sealant can be effectively scraped on all parts at the beginning and end of scraping.

[0025] In the embodiment of the present invention, the first-order glue dispensing head 1 and the second-order glue dispensing head 2 have the same width, and the farthest net distance between the first-order glue dispensing head 1 and the second-order glue dispensing head 2 is n times the width of the first-order glue dispensing head 1, where n is a positive integer.

[0026] Preferably, n is the ratio of the time taken for the surface of the sealant to initially solidify to the movement time of the first-sequence glue head 1; wherein, the movement time of the first-sequence glue head 1 is the sum of the time taken for the first-sequence glue head 1 to rotate one circle along the center line 9 of the gas storage reservoir and the time taken for the glue machine 8 to move one width of the first-sequence glue head 1.

[0027] Specifically, a first-order glue outlet head 1 and a second-order glue outlet head 2 are provided at the end of the glue guide tube 3, and the widths of the first-order glue outlet head 1 and the second-order glue outlet head 2 are both l , the clearance between the first-order glue head 1 and the second-order glue head 2 is L. L and l The relationship between integer multiples: L=n l , n is an integer, and the multiple n is based on the time taken for the sealant surface to initially solidify, the time taken for the first glue head 1 to rotate one circle along the lining 10, and the distance taken for the glue machine 8 to move one glue head l The duration is determined by the formula shown below.

[0028] n = t1 / (t2+t3); Among them, n is a multiple, and the calculation result is rounded; t1 is the time taken for the sealant surface to initially solidify; t2 is the time taken for the first-order glue head 1 to rotate one circle along the center line 9 of the gas storage reservoir; t3 is the time taken for the glue machine 8 to move one glue head width l Duration.

[0029] The effect of this setting is that after the first-order glue head 1 jumps out of the chamber to apply the first-order glue layer, the sealant that has been scraped and applied when the second-order glue head 2 applies glue has a certain strength, ensuring the thickness of the second-order glue.

Its main purpose is to form a convex slope on both sides of the first-order glue layer, and form a pressure slope joint with the concave slopes on both sides of the second-order glue layer, so that the two-order sealants are closely connected. A first-order spring bellows 13 is arranged between the first-order glue box 11 and the glue inlet pipe 3. The purpose of arranging the first-order spring bellows 13 is to ensure that the first-order glue head 1 is always pressed on the surface of the concrete lining 10, so that the sealant is scraped on the concrete lining 10. In addition, when the surface of the concrete lining 10 is uneven, it can automatically adjust; arc guide plates 14 are arranged on both sides of the first-order glue box 11. The arc guide plates 14 are arc-shaped, and the arc radius is the same as the radius of the circular gas storage reservoir, and the length is 20cm~30cm. The purpose is to ensure that when the surface of the concrete lining 10 has uneven defects, the first-order glue head 1 can stably cross the uneven parts of the concrete surface and ensure the thickness of the sealant scraping.

[0033] The structure of the second-order glue head 2 is as follows Figure 7, consisting of a second-order glue box 21, a second-order glue outlet 22, a second-order spring bellows 23 and a pressing plate 24. The thickness h of the second-order glue outlet 22 can be set according to the required sealant thickness, and this setting can effectively ensure the thickness of the scraped sealant; the second-order glue outlet 22 is set to a concave inverted trapezoid, and its top angle α is between 45° and 60°, and is the same as the bottom angle α of the first-order glue outlet 12 of the first-order glue outlet head 1. Its main purpose is to form a concave slope on both sides of the second-order glue layer, and form a pressure slope seam with the convex slopes on both sides of the first-order glue layer, so that the two-order sealants are closely connected. The pressing plates 24 are set on both sides of the second-order glue box 21 in a rectangular shape, with a width of 5cm~10cm and a length of 5cm, of which 2cm is welded to the second-order glue box 21. The purpose of setting the pressing plate 24 is to press it on the surface of the first-order glue layer that has been hit, so as to ensure the glue thickness of the second-order glue layer. A second-order spring bellows 23 is arranged between the second-order glue box 21 and the glue inlet pipe. The purpose of arranging the second-order spring bellows 23 is to ensure that the pressing plate 24 is always pressed on the surface of the first-order glue layer.
