[0017] The utility model discloses a portable marsh gas pool seal cover uncapping device, one kind of portable marsh gas pool seal cover uncapping device mainly includes L type bottom plate 1, support 2, reinforcing rib plate 3, screw rod 4, handle 5, limit plate 6, U type connecting piece 7, connecting bolt 8, the support 2 vertical installation in L type bottom plate 1 top, and the support 2 top is provided with the through screw hole, and the reinforcing rib plate 3 is installed on the support 2, and the screw rod 4 is rotatably installed on the support 2 through the screw hole, and the handle 5 for driving the screw rod 4 rotation is installed on the screw rod 4, and two limit plates 6 are symmetrically installed on both sides of the support 2, and the vertical direction's sliding slot 61 is set up on the limit plate 6, and the U type connecting piece 7 is rotatably installed on the screw rod 4 bottom, is located in the sliding slot 61 inside, and the connecting bolt 8 for connecting marsh gas pool seal cover 9 handle 91 can be detachably installed on the U type connecting piece 7.

[0018] The horizontal section of the L-shaped bottom plate 1 is provided with anti-skid lines, and the vertical section is provided with mounting holes 11 matched with the support 2; the reinforcing rib plate 3 is triangularly distributed on both sides of the support 2; the L-shaped bottom plate 1, the support 2, the reinforcing rib plate 3 and other structural components in the device cooperate with each other to form a stable support system, which can bear the weight of the seal cover 9 and the acting force when the seal cover 9 is opened during the uncapping process, ensures the stability of the device, and further improves the safety of operation.

[0019] As shown in Figure 2 , Figure 3 , the handle 5 includes a connecting ring 51 and two symmetrically arranged auxiliary handlebars 52, the connecting ring 51 is fixedly installed on the screw rod 4, the auxiliary handlebars 52 are installed on the connecting ring 51, and the surface of the auxiliary handlebars 52 is covered with an anti-skid rubber layer; when it is necessary to open the seal cover 9, the operator holds the auxiliary handlebars 52 and rotates them to drive the connecting ring 51 and the screw rod 4 to rotate, so that the U-shaped connecting piece 7 moves vertically along the sliding slot 61.

[0020] The sliding slot 61 of the limit plate 6 is embedded with a high-molecular wear-resistant bushing; the design of the limit plate 6 and the sliding slot 61 can limit the movement of the U-shaped connecting piece 7, ensure that the U-shaped connecting piece 7 can only move along the vertical direction during the rotation of the screw rod 4, make the seal cover 9 open smoothly, avoid the seal cover 9 from shaking or deviating, and the main function of the high-molecular wear-resistant bushing is to reduce friction and wear, thereby prolonging the service life of the limit plate 6 and the U-shaped connecting piece 7 and improving work efficiency.

[0021] Working process:

[0022] The horizontal section of the L-shaped bottom plate 1 is close to the edge of the biogas tank, and the anti-skid lines realize the stable fixing position of the equipment by increasing the friction force, the position of the adjusting device is adjusted to ensure that the center of the support 2 is aligned with the center line of the tank cover, the rotating handle 5 drives the screw rod 4 to rotate, so that the U-shaped connecting piece 7 is lowered to the lowest working position, then the connecting bolt 8 is penetrated through the handle 91 of the sealing cover 9 to fix the sealing cover 9 at the bottom end of the U-shaped connecting piece 7, so as to ensure that the U-shaped connecting piece 7 and the handle 91 form stable connection, and rotating the handle 5 makes the screw rod 4 rotate in the threaded hole of the support 2, since the U-shaped connecting piece 7 is rotatably installed at the bottom end of the screw rod 4 and located in the sliding groove 61 of the limiting plate 6, the rotation of the screw rod 4 drives the U-shaped connecting piece 7 to move up and down along the sliding groove 61, so as to adjust the height of the biogas tank sealing cover 9.

[0023] When it is needed to open the biogas tank sealing cover 9, the handle 5 is forwardly rotated to make the screw rod 4 rise, and the U-shaped connecting piece 7 moves upward, the handle 91 of the biogas tank sealing cover 9 is pulled up through the connecting bolt 8 to realize the opening operation, and the material adding is performed, in the opening process, the limiting plate 6 can limit the rotation of the U-shaped connecting piece 7, so as to ensure that it can only move in the vertical direction, thereby ensuring the stability and safety of the opening, and the reinforcing plate 3 continuously provides the bending moment to prevent the deformation of the support 2 in the lifting process.

[0024] After the material adding is completed, the biogas tank sealing cover 9 needs to be closed, the handle 5 is reversely rotated to make the screw rod 4 descend, and the U-shaped connecting piece 7 moves downward, the sealing cover 9 slowly resets under the action of gravity to complete the closing operation, after the operation is completed, the connecting bolt 8 is loosened to separate the device from the sealing cover 9, so as to be transferred to other biogas tanks for repeated use.
