Description

Technical Field

[0001] The present disclosure relates to the technical field of substation operation and maintenance detection, and in particular to a substation operation and maintenance detection device. Background Art

[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid. During the stable operation of the substation, it is necessary to regularly use detection devices to maintain and inspect the operation and maintenance equipment of the substation. However, the existing detection devices have a single function. When inspecting the operation and maintenance equipment with complex structures, some hidden parts of the equipment are not easy to be detected, which increases the difficulty of the workers' work.

[0003] The inventors have found that it is difficult to perform leakage detection on hidden parts of operation and maintenance equipment with the existing technology. At the same time, insects, sand, etc. may exist in the hidden parts over time. The current detection device cannot achieve the unification of leakage detection and dehumidification and insect removal of hidden parts of operation and maintenance equipment. The detection steps are relatively complicated. At the same time, the electric tester is always exposed to the outside, which can easily cause damage to the electric tester. Therefore, this application proposes a substation operation and maintenance detection device to solve the above problems. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, the present invention provides a substation operation and maintenance detection device, which uses a handheld rod and can simultaneously complete the dehumidification, insect removal and leakage detection steps.

[0007] The interior of the hand-held pole is divided into an air inlet channel area and a lifting area. The lifting area is provided with a lifting device, and a voltage tester with an audible alarm is provided on the top of the lifting device. The lifting area inside the hand-held pole is also provided with a partition, and a blowing hood is provided on the top of the hand-held pole.

[0009] Furthermore, the lifting device also includes two push rods, a ring and a base. The ring is threadedly connected to the spiral shaft, the two push rods are fixedly connected to the ring, and the other ends of the two push rods pass through the partition and are fixedly connected to the base. The rotation of the spiral shaft can realize the lifting movement of the base driven by the ring through the push rod.

[0010] Furthermore, the storage battery on the bracket is connected to the suction fan through a wire and the fan, and supplies power to the fan and the suction fan at the same time.

[0011] Furthermore, the suction fan is connected to the collection box through an air pipe to form a negative pressure area inside the collection box. The collection box can also be connected to the air inlet channel of the handheld rod through a first hose.

[0012] Furthermore, a lighting lamp is provided on the blow hood, which is controlled by a control switch on the hand-held rod.

[0013] Furthermore, the bracket also includes universal wheels, which are arranged below the bottom plate of the bracket. The universal wheels are installed on the four corners of the bottom plate, and there are four of them.

[0014] Furthermore, a handle is provided above the bracket, and the handle is wrapped with an insulating sleeve.

[0015] Furthermore, a filter screen is provided inside the collection box and a sealing cover is provided on the top.

[0016] Furthermore, the spiral shaft is rotationally connected to the fixing seat, and the push rod and the sleeve are an integral structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

The dehumidification and pest control and leakage detection steps can be realized simultaneously with the hand-held pole, and the detection efficiency is greatly improved.

[0019] 2. The lifting area of ​​the present invention is provided with an electric test pen with sound alarm. When leakage detection is not needed, the electric test pen can be retracted into the inside of the hand-held pole, which will not interfere with the blowing, dehumidification and insect removal steps of the air inlet channel and will not cause damage to the electric test pen with sound alarm. When leakage detection is needed, the electric test pen is extended to the outside of the blowing hood through a rotating motor to perform leakage detection. At the same time, the lighting lamp on the blowing hood can provide lighting, thereby facilitating the detection of operation and maintenance equipment.

[0020] 3. The suction fan can also form negative pressure at the collection box connected to it through the air pipe through operation, so the present invention can not only achieve blowing, but also choose to recycle insect corpses, small stones, etc. into the collection box.
