Embodiment 1

[0018] like figure 1 , figure 2 As shown, the lifting mechanism of the drainage pump for the fire well of the substation described in this embodiment includes a base plate 1, a support frame 2 arranged on the base plate 1 and a roller 3 arranged under the base plate 1. The top of the support frame 1 is provided with The drum 4, one end of the drum 4 is provided with a handle 5 for rotating the drum 4, a pull rope 6 is wound on the drum 4, and the free end of the pull rope 6 is connected with a hook 7 for connecting the drainage pump;

[0019] The bottom plate 1 of the present embodiment is provided with a through hole 8, and a groove body 9 matching the shape of the through hole 8 is clamped on the through hole 8. One end of the groove body 9 is connected with the bottom plate 1 by a hinge, and the groove body 9 can be upward Open, so that the entire through hole 8 is exposed, which is convenient for the drainage pump to pass through.

[0020] like image 3 As shown, the m...

Embodiment 2

[0023] On the basis of Embodiment 1, the present embodiment defines the roller 3 as follows: the roller 3 in this embodiment is a universal wheel, so as to facilitate the position adjustment of the lifting structure, so that the through hole 8 is located at the center of the wellhead as much as possible. The steering wheel has a locking structure, and the locking structure can keep it in that position after the lifting structure is selected, which is convenient for stable operation. The locking structure is the existing structure in the field, and many rollers are currently used. , such as a stroller or some trolleys, the rollers have a locking structure, so the specific structure will not be repeated here.

Embodiment 3

[0025] In this embodiment, on the basis of Embodiment 1, the notch 10 is defined as follows: the part of the notch 10 in this embodiment close to the center of the groove body 9 is provided with a semicircular rubber strip, thereby reducing the size of the pull rope 6 and the groove body 9 The friction between them improves the stability and safety of the operation, and also prolongs the service life of the pull rope 6 .

Abstract

The invention discloses a drainage pump lifting mechanism for substation fire wells, comprising a bottom plate, a support frame arranged on the bottom plate and rollers arranged under the bottom plate, a roller is arranged on the top of the support frame, and a roller is provided at one end of the roller The rocker of the drum, the drum is wound with a drawstring, and the free end of the drawstring is connected with a hook for connecting the drainage pump; the bottom plate is provided with a through hole, and the through hole is fitted with a groove matching the shape of the through hole One end of the tank body is connected to the bottom plate by a hinge; the movable end of the tank body is provided with a notch extending to the center of the tank body, the notch is located directly below the drum, and a baffle plate is provided on the edge of the notch, the baffle plate One end and the edge of the notch are hinged. The present invention adopts the above structure, which can avoid friction or collision between the drainage pump and the well wall during the lifting process, and prevent the drainage pump from being damaged.

Description

technical field [0001] The invention relates to the field of placement of drainage pumps, in particular to a drainage pump lifting mechanism used for fire wells in substations. Background technique [0002] The substation is a place where the voltage is changed. In order to transmit the electric energy output by the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and the voltage must be lowered as needed near the user. This step-up and step-down work Mainly rely on the substation to complete. In order to prevent rainstorms, floods, etc. from affecting the substation, ensuring good drainage is the focus of flood control in the substation. General substations are equipped with fire wells. In order to discharge the accumulated water in the fire well, a drainage pump needs to be put into the fire well. At present, there is a more traditional method. 2~3 operators put the drainage pump into the fire well with bare hands. This metho...
