A detachable telescopic rod specially used for fire detection

Abstract

The invention discloses a detachable telescopic rod specially used for fire detection. The structure of the telescopic rod comprises a cylinder, a telescopic rod and a disassembly detection mechanism. The lower end of the telescopic rod is installed inside the cylinder by a clearance fit, and the top of the telescopic rod is provided with a disassembly detection mechanism. The opening and closing piece is squeezed by an electric wire, and the electric wire enters the inside of a shrinking plate individually, and then the outer side of the electric wire contacts the contact piece. At this time, a sliding shaft at the inner end of the fixed rod slides on the right end of the contact piece, so that the size of the openings at the left ends of the upper and lower contact pieces is adjusted to ensure that the outer side of the electric wire is tightly contacted, so that effective time-length contact detection is performed on the individual electric wires. The plate body is driven by the telescopic hose to perform elastic squeezing, so that the plate body and the elastic pull rope support the other electric wires except the electric wire to be tested, so as to avoid a plurality of electric wires being gathered together and improve the accuracy of the detection data.

Description

Technical Field

[0001] The invention relates to the field of fire detection, and more specifically, to a detachable telescopic rod specially used for fire detection. Background Art

[0002] The inspection of building fire protection facilities is to use specified methods to test the specific technical performance indicators of building fire protection facilities for each system of the building fire protection facilities. When inspecting electricity at high places in buildings, it is necessary to use telescopic rods to extend and retract to reach the inspection height. However, in the process of inspecting electricity at high places, when the wires at high places are relatively dense, the contact effect of the detection head on the top of the telescopic rod and the wires to be inspected is difficult to maintain for a long time. As a result, during the inspection process, the data detected by the detection head is relatively incomplete. At the same time, it is difficult for the top of the telescopic rod to stretch out the wires other than those to be inspected, which makes it easy for the detection head on the top of the telescopic rod to come into contact with multiple wires at the same time, resulting in certain errors in the inspection data. Summary of the invention

The lower end of the disassembly rod is installed on the top of the telescopic rod, and the opening and closing mechanism is provided on the top of the disassembly rod, and an external support mechanism is installed on the outside of the opening and closing mechanism.

[0004] As a further improvement of the present invention, the opening and closing mechanism includes an outer ring, an opening and closing plate, a torsion shaft, and a guide mechanism.

[0005] As a further improvement of the present invention, the guiding mechanism includes a necking plate, a connecting rod, a pulley, a conducting wire, a strut, and a contact mechanism. The left end of the necking plate is welded to the inner wall of the left side of the outer ring, and the interior of the necking plate is fixed to the outer end of the connecting rod. A pulley is provided at the inner end of the connecting rod. The right end of the necking plate is fixed to the left end of the contact mechanism. The conducting wire runs through the interior of the strut, and the conducting wire is electrically connected to the interior of the contact mechanism. The top of the strut is welded to the bottom of the contact mechanism, and the strut is installed on the top of the disassembly rod. A hose is provided at the middle end of the connecting rod, and the hose has a pleated structure, is made of rubber, and has a certain degree of elasticity.

[0006] As a further improvement of the present invention, the contact mechanism includes an arc plate, a fixed rod, a sliding shaft, a contact piece, and a data transmission line. The bottom plate of the arc plate is welded to the top of the support rod, the inner wall of the arc plate is welded to one end of the fixed rod, and a sliding shaft is provided at the inner end of the fixed rod, and the sliding shaft is slidably installed inside the right end of the contact piece, the middle part of the contact piece is fixed to the data transmission line, and the data transmission line is electrically connected to the wire, and two of the fixed rod, sliding shaft, contact piece and data transmission line are each provided, and are installed in an upper and lower symmetrical structure.

During the test, the wires other than the wire to be tested move on the plate. At this time, the ball rotates along the fixed axis to assist the sliding of the plate and the surface of the wire, preventing jamming during the mobile test and improving the accuracy of the test.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] As attached Figure 1 To Attachment Figure 5 As shown:

[0023] The present invention discloses a detachable telescopic rod specially used for fire detection, and its structure comprises a cylinder 1, a telescopic rod 2, and a disassembly detection mechanism 3. The lower end of the telescopic rod 2 is installed inside the cylinder 1 by a clearance fit, and the top of the telescopic rod 2 is provided with a disassembly detection mechanism 3, and the disassembly detection mechanism 3 comprises a disassembly rod 31, an opening and closing mechanism 32, and an external support mechanism 33. The lower end of the disassembly rod 31 is installed on the top of the telescopic rod 2, and the opening and closing mechanism 32 is provided on the top of the disassembly rod 31, and the external support mechanism 33 is installed on the outside of the opening and closing mechanism 32.

[0024] Among them, the opening and closing mechanism 32 includes an outer ring 321, an opening and closing piece 322, a torsion shaft 323, and a guide mechanism 324. The lower end of the outer ring 321 is fixedly installed on the top of the disassembly rod 31, and the left side of the outer ring 321 is hinged to the opening and closing piece 322 through the torsion shaft 323. The left end of the guide mechanism 324 is fixed to the inner wall of the left side of the outer ring 321. An external support mechanism 33 is installed on the outside of the outer ring 321. The outer ring 321 is a circular ring structure, and an opening is provided at the left end. Two opening and closing pieces 322 and a torsion shaft 323 are provided at the opening. The two opening and closing pieces 322 and the torsion shaft 323 are symmetrically installed up and down. When the elastic torsion force is applied by the torsion shaft 323 so that the wire contacts the opening and closing piece 322, the opening and closing piece 322 is automatically opened and closed, so that the wire enters the guide mechanism 324 alone.

[0025] Among them, the guiding mechanism 324 includes a shrinking plate 24a, a connecting rod 24b, a pulley 24c, a wire 24d, a strut 24e, and a contact mechanism 24f. The left end of the shrinking plate 24a is welded to the inner wall of the left side of the outer ring 321, and the inside of the shrinking plate 24a is fixed to the outer end of the connecting rod 24b. The inner end of the connecting rod 24b is provided with a pulley 24c. The right end of the shrinking plate 24a is fixed to the left end of the contact mechanism 24f. The wire 24d runs through the inside of the strut 24e, and the wire 24d is electrically connected to the inside of the contact mechanism 24f. The top of the strut 24e is welded to the bottom of the contact mechanism 24f, and the strut 24e is installed on the top of the disassembly rod 31. The middle end of the connecting rod 24b is provided with a hose, and the hose is a pleated structure, made of rubber material, and has a certain elasticity, ensuring that the pulley 24c assists in guiding and sliding wires of different diameters, ensuring that the wires smoothly enter the contact mechanism 24f for detection.

[0026] Among them, the contact mechanism 24f includes an arc plate f1, a fixed rod f2, a sliding shaft f3, a contact piece f4, and a data transmission line f5. The bottom plate of the arc plate f1 is welded to the top of the support rod 24e, the inner wall of the arc plate f1 is welded to one end of the fixed rod f2, and a sliding shaft f3 is provided at the inner end of the fixed rod f2, and the sliding shaft f3 is slidably installed inside the right end of the contact piece f4. The middle part of the contact piece f4 is fixed to the data transmission line f5, and the data transmission line f5 is electrically connected to the conductor 24d. The fixed rod f2, the sliding shaft f3, the contact piece f4 and the data transmission line f5 are each provided with two, and are installed in an upper and lower symmetrical structure. When wires of different diameters come into contact with the contact piece f4, they slide on the right end of the contact piece f4 through the sliding shaft f3, so that the openings at the left ends of the two contact pieces f4 are automatically adjusted to ensure close contact with the outside of the wires, thereby detecting the wires.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, the telescopic rod 2 is pushed up by starting the cylinder 1, and the telescopic rod 2 and the disassembly rod 31 can be disassembled. When the telescopic rod 2 rises, the disassembly rod 31 is driven up to move the opening and closing mechanism 32 to the vicinity of the wire to be detected. After approaching the wire, the opening and closing piece 322 is squeezed through the wire, so that the opening and closing piece 322 rotates around the torsion shaft 323. At this time, the wire enters the inside of the shrinking plate 24a alone. According to the diameter of the wire itself, the outer side of the wire conflicts with the pulley 24c, so that the connecting rod 24b drives the pulley 24c to adjust the telescopic adjustment, ensuring that the pulley 24c assists the wires of different diameters to slide smoothly into the arc plate f1, and then the outer side of the wire contacts with the contact piece f4. At this time, the sliding shaft f3 at the inner end of the fixed rod f2 slides on the right end of the contact piece f4, so that the openings at the left ends of the upper and lower contact pieces f4 are adjusted in size, ensuring that the outer side of the wire is tightly contacted, so that the individual wires can be effectively tested for the contact time.

[0029] Embodiment 2:

[0030] As attached Figure 6 To Attachment Figure 7 As shown:

[0031] Among them, the external support mechanism 33 includes a telescopic hose 331, an extrusion rod 332, a support plate mechanism 333, and an elastic pull rope 334. The telescopic hose 331 is installed inside the outer side of the outer ring 321, and the outer end of the telescopic hose 331 is fixed to the inner end of the extrusion rod 332. The inner end of the extrusion rod 332 is installed inside the outer side of the outer ring 321 with a clearance fit. An elastic pull rope 334 is provided on the outside of the support plate mechanism 333. The telescopic hose 331 is in a pleated structure and is made of rubber material. It has a certain resilience and good insulation. The support plate mechanism 333 is driven by the telescopic hose 331 to perform elastic extrusion, so that the support plate mechanism 333 can support other wires other than the wires to be tested, avoid multiple wires from being gathered together, and improve the accuracy of the detection data.

[0032] Among them, the support mechanism 333 includes a plate body 32a, a ball 32b, and a fixed shaft 32c. The inner end of the plate body 32a is fixed to the outer end of the telescopic hose 331, and an elastic pull rope 334 is provided on the outer side of the plate body 32a. The ball 32b is hinged to the inner part of the outer end of the plate body 32a through the fixed shaft 32c. The plate body 32a has an arc-shaped structure, and there are three ball 32b, which are equidistantly distributed in an arc on the plate body 32a, which is beneficial for the plate body 32a to assist the sliding of other wires during the movement, thereby preventing jamming during the mobile detection process.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the present invention, during the detection process, the plate body 32a is driven by the telescopic hose 331 to perform elastic extrusion, and at the same time, the elastic pull rope 334 between the plate body 32a is elastically deformed, so that the plate body 32a and the elastic pull rope 334 support other wires other than the wire to be tested, avoiding multiple wires from being gathered together, thereby improving the accuracy of the detection data. During the detection process, it is necessary to move and perform synchronous detection on multiple locations of the same wire. During the movement, other wires other than the wire to be tested move on the plate body 32a. At this time, the ball 32b rotates along the fixed shaft 32c, which plays an auxiliary sliding role between the plate body 32a and the surface of the wire, thereby preventing jamming during the mobile detection process and improving the accuracy of the detection.

[0035] Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
