[0034] The following will be described in detail in combination with the accompanying drawings Figures 1-6 The present application will be further described in detail.

[0035] Embodiment 1

[0036] The embodiment of the present application discloses a multifunctional well lid opening auxiliary device. Referring to Figure 1 , the opening auxiliary device comprises a mounting seat 1, a force applying rod 2 rotatably arranged on the mounting seat 1, and a force applying seat 3 arranged at the end of the force applying rod 2 away from the mounting seat 1, wherein the force applying rod 2 is arranged in two and symmetrically arranged on the mounting seat 1, and the rotation axes of the two force applying rods 2 are parallel to each other, so that the lower ends of the two force applying rods 2 can rotate towards the direction of moving away from each other or moving close to each other, so as to adjust the included angle formed between the two force applying rods 2; the force applying seat 3 extends out of the side wall of the force applying rod 2 at both ends, so as to be inserted into the reserved hole 104 of the well lid.

[0037] Referring to Figure 1 and Figure 2 , the existing well lid generally comprises a heat well lid 101 provided with a reserved seat, a common double-hole well lid 102 and a common single-hole well lid 103, wherein the heat well lid 101 is also provided with two reserved seats, the force applying seat 3 can be inserted into the reserved hole 104 in the reserved seat, and can also be inserted into the reserved hole 104 of the common double-hole well lid 102, so that when the heat well lid 101 or the common double-hole well lid 102 needs to be opened, the two force applying rods 2 are only needed to be rotated to control the insertion of the inner end part of the force applying seat 3 into the reserved hole 104, and then the expansion of the two force applying rods 2 is limited, so that the well lid can be lifted upwards.

[0038] Further, the length of the force applying seat 3 is less than the length of the reserved hole 104 of the common well lid and greater than the width of the reserved hole 104 of the common well lid, so that for the common single-hole well lid 103, the force applying seat 3 on one of the force applying rods 2 can be inserted into the reserved hole 104 first, and then rotated by 90 degrees to cross the reserved hole 104, so that the well lid can be lifted upwards to be opened. Optionally, the common double-hole well lid 102 can also be opened in this way according to needs.

[0039] Referring to Figure 1 and Figure 3 , in the embodiment of the present application, the mounting seat 1 serves as the basic structure of the whole device, which comprises a first side plate 11, a second side plate 12 and two anchor shafts 13, wherein the first side plate 11 and the second side plate 12 are mutually parallel rectangular plates, and the two anchor rods are fixed between the first side plate 11 and the second side plate 12 for fixing the force applying rods 2, the upper ends of the two force applying rods 2 are rotatably arranged on the two anchor shafts 13, and the side of the upper ends of the two force applying rods 2 close to each other is preferably arranged in an arc shape to avoid interference between the two force applying rods 2 when the force applying rods 2 rotate. The first side plate 11 and the second side plate 12 can be made of high-strength steel plates, which have good strength and rigidity to ensure the stability of the overall structure; the anchor shaft 13 can be a solid steel shaft or a hollow steel pipe to ensure good stress strength.

[0040] Further, the mounting seat 1 further comprises a force ring 14, the two ends of which extend to the first side plate 11 and the second side plate 12, and the outer surface thereof can be inserted into the force ring 14 when it is necessary to control the mounting seat 1, and the manhole cover can be lifted by applying force to the force ring 14, thereby improving the convenience of operation. The side wall of each force lever 2, which is close to the other force lever 2, is provided with a clearance groove 21 for avoiding the force ring 14, and the shape and size of the clearance groove 21 should match those of the force ring 14, so that a proper gap is ensured between them.

[0041] With reference to Figure 1 and Figure 3 In the embodiment, the force seat 3 can be an integrally formed stainless steel plate, and the side upper surface thereof, which faces the other force lever 2, is provided with an inclined abutting surface and a horizontal clamping surface. When the force seat 3 is obliquely inserted into the reserved hole 104, the inclined abutting surface and the horizontal clamping surface are clamped to the edge of the manhole cover reserved hole 104, so that the manhole cover is stably clamped.

[0042] With reference to Figure 1 and Figure 3 In an alternative embodiment, the cover opening auxiliary device further comprises a limiting sleeve ring 4, which is preferably provided in a rectangular ring structure, is sleeved on the outer side of the force lever 2, and can freely move in the up-down direction. In use, the limiting sleeve ring 4 can be first moved upward, and then the two force levers 2 are rotated so that the inner side of the mounting seat 1 at the lower end of the force lever 2 is obliquely inserted into the reserved hole 104 and abuts against the reserved hole 104. At this time, the limiting sleeve ring 4 can be moved downward so that the lower part of the limiting sleeve ring 4 abuts against the side wall of the force lever 2, thereby clamping the force lever 2 and limiting the outward rotation of the force lever 2, thereby improving the stability during lifting of the manhole cover.

[0043] The implementation principle of the multifunctional manhole cover opening auxiliary device in the embodiment is as follows: when it is necessary to open the manhole cover, the force lever 2 is first controlled to open, the force seat 3 is inserted into the manhole cover reserved hole 104, and clamping is realized by using the inclined abutting surface and the horizontal clamping surface; then the limiting sleeve ring 4 is moved downward to clamp the force lever 2, and finally external force is applied through the force ring 14, so that the manhole cover can be lifted upward. Compared with the traditional crowbar, the device not only is more labor-saving in operation, but also can effectively avoid damage to the edge of the reserved hole 104. At the same time, when the manhole cover is lifted, the manhole cover can be clamped and limited, so that the manhole cover is prevented from falling and the safety hazard is reduced.

Further, the limiting grooves 22 extend into a waist-shaped groove along the width direction of the force applying rod to adapt to different opening angles. When the limiting column 51 is inserted into the limiting groove 22, the limiting spring 52 is in a compressed state, thereby being able to provide a certain elastic force to ensure that the limiting column 51 is firmly embedded in the limiting groove 22.
