Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable channel inspection device. Background Art

[0002] Cables are important carriers for the transmission of electric energy and information. If a cable fails, it will cause huge losses to people's work, life, and industrial production. Most of the current wires and cables are laid in underground pipelines or cable trenches. In order to ensure the normal operation of the line for a long time, it is necessary to conduct regular inspections inside it. In the existing technology, most of the inspections of cable trenches are still done manually. There are many inconveniences in manual inspections. For example, the space in the power cable trench is small, the number of equipment is large, the distribution points are large, and the total mileage is long, resulting in the shortcomings of large amount of monitoring information, long monitoring distance, and short inspection cycle. At the same time, it has problems such as easy accumulation of water, easy generation of harmful gases, poor air circulation, high voltage, and high radiation, which makes manual inspection work extremely difficult. There is an urgent need for cable tunnel inspection robots to replace manual inspections.

[0003] Many existing inspection devices are prone to collision during the process of moving in the channel, thereby damaging inspection sensors and other precision instruments. Therefore, an anti-collision protection for cable channel inspection devices is urgently needed. Utility Model Content

[0004] One purpose of the utility model is to provide a cable channel inspection device, which can protect the inspection device from collision through a buffer platform and a buffer plate, thereby protecting the inspection sensor.

[0005] This purpose is achieved by adopting the following technical solutions:

[0006] A cable channel inspection device includes a mobile station, a buffer station is provided at the front end of the mobile station, buffer plates are provided on two opposite sides of the mobile station, a transmission structure is connected inside the mobile station, one end of the transmission structure is connected to the buffer station, and the other end of the transmission structure is connected to two buffer plates. During the inspection movement of the inspection device, the device moves forward. If the front end of the mobile station is hit, the buffer station moves toward the direction close to the mobile station. Since there is a distance between the buffer station and the mobile station, when the front end of the mobile station is hit, the buffer station can have a buffering effect and can protect the mobile station. At the same time, when the buffer station moves toward the direction close to the mobile station, the transmission structure drives the two buffer plates to move in the direction away from the side of the mobile station respectively. The two buffer plates protect the side of the mobile station.

[0007] When the existing device is in use, the front end of the existing device has a buffer platform, and when the front end is hit, the buffer platform can provide buffer protection. However, when the front end is hit, the inspection device is prone to deflect left and right. When deflecting left and right, the side of the mobile platform is prone to be hit, which can easily damage the inspection sensor. The buffer platform, transmission structure and buffer plate of the device can protect the two sides of the device at the same time when the front end is hit, thereby improving the anti-collision effect.

[0008] Furthermore, an arc-shaped spring piece is arranged between the transmission structure and the buffer plate of the device, and the arc-shaped spring piece is in an arc shape that is concave inwards; the two buffer plates are in the same shape as the arc-shaped spring piece, and the arc-shaped spring piece and the buffer plate are in contact with each other; wherein the arc-shaped spring piece can change from an arc shape that is concave inwards to an arc shape that is convex outwards under the action of an external force, and in the original state, the arc-shaped spring piece is in an arc shape that is concave inwards, and when the buffer platform moves toward the direction close to the mobile platform, the transmission structure acts on the arc-shaped spring piece to push the arc-shaped spring piece outwards, and then the arc-shaped spring piece changes from an arc shape that is concave inwards to an arc shape that is convex outwards, and when the arc-shaped spring piece changes, it drives the buffer plate together from an arc shape that is concave inwards to an arc shape that is convex outwards. The arc shape that is convex outwards can have a better anti-collision protection effect and is more conducive to long-term use.

[0009] Preferably, the buffer plate is an air cushion layer, which can not only adapt to the shape change of the arc-shaped spring piece, but also has a better protective effect to prevent collision.

[0010] Furthermore, a first groove is provided at the front end of the movable platform, and two second grooves are provided on the inner side surface of the first groove. The transmission structure includes a first transmission rod and two second transmission rods. The first transmission rod is located in the first groove, and one end of the first transmission rod is connected to the buffer platform; the two second transmission rods are respectively located in the two second grooves, and one end of the two second transmission rods is respectively connected to the two buffer plates; the other end of the first transmission rod is provided with two first action surfaces, and the other ends of the two second transmission rods are both provided with second action surfaces. The two first action surfaces of the first transmission rod can respectively act on the second action surfaces of the two second transmission rods, so that the two second transmission rods move in the two second grooves respectively and drive the two buffer plates to move.

[0011] In addition, first springs are disposed on the side surfaces of the two second transmission rods, first grooves are disposed on the inner sides of the two second grooves, the first springs are respectively located in the corresponding first grooves, and the first springs are used to drive the buffer plate to move.

[0012] A second spring is arranged between the buffer platform and the moving platform.

[0013] When impacted, the first spring and the second spring are compressed, driving the first transmission rod and the second transmission rod to move, thereby protecting the device from impact. At the same time, when no external force is applied, the device returns to its original state under the action of the first spring and the second spring.

[0014] Preferably, the end of the buffer platform away from the moving platform is an arc convex outward. The lower end of the buffer platform is provided with a baffle. The lower end of the baffle is provided with a plurality of rollers. The lower end of the moving platform is provided with a pulley.

[0015] The pulley can be used to facilitate the movement of the device to the desired position. During the movement of the inspection device, the baffle is used to block obstacles to avoid increasing the risk of the inspection device rolling over during the movement.

[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0017] The utility model discloses a cable channel inspection device. During the inspection process, the front end and the side of the device are protected by a buffer table and a buffer plate respectively, so as to avoid the device being damaged when being hit.

[0018] The buffer platform and the buffer plate of the device are connected through a transmission structure. When impacted, the buffer plate provides protection at the same time without the need for additional operation, thereby achieving a better anti-collision effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] like Figure 1 As shown, it includes a mobile platform 1, a pulley 11 is arranged at the lower end of the mobile platform 1, and the mobile platform 1 drives the device to move in the channel through the pulley. A detection structure 10 is arranged on the mobile platform 1, and the detection structure 10 includes a wireless communication device, a battery, a camera pan head, a CO sensor, a smoke sensor and a main control board; the camera pan head, the CO sensor, and the smoke sensor are used to detect cables, and the detected data are uploaded to the background through the wireless communication device.

[0030] A buffer platform 6 is provided at the front end of the mobile platform 1, and buffer plates 9 are provided on two opposite sides of the mobile platform 1. A transmission structure is connected inside the mobile platform 1, one end of the transmission structure is connected to the buffer platform 6, and the other end of the transmission structure is connected to the two buffer plates 9. When the buffer platform 6 moves toward a direction close to the mobile platform 1, the transmission structure drives the two buffer plates 9 to move in directions away from the sides of the mobile platform 1.

[0031] The transmission structure may be of various structures, as long as it can achieve the effect that when the buffer platform 6 moves toward the direction close to the moving platform 1 , the transmission structure drives the two buffer plates 9 to move toward the direction away from the side of the moving platform 1 .

[0032] The mobile platform moves forward. When the front end of the mobile platform is hit, the buffer platform at the front end of the mobile platform is hit first and moves toward the direction close to the mobile platform 1. During the movement, the transmission structure acts on the buffer plates on the two sides of the mobile platform, and the two buffer plates move toward the direction away from the side of the mobile platform 1, thereby protecting the mobile platform and preventing the front and rear ends from being hit.

[0033] Example 2

[0034] Based on the above embodiments, Figure 2 As shown, a second spring 7 is provided between the buffer table 6 and the moving table 1. A first groove 2 is provided at the front end of the moving table 1, and two second grooves 3 are provided on the inner side of the first groove 2. The transmission structure includes a first transmission rod 5 and two second transmission rods 4. The first transmission rod 5 is located in the first groove 2, and one end of the first transmission rod 5 is connected to the buffer table 6; the two second transmission rods 4 are respectively located in the two second grooves 3, and one end of the two second transmission rods 4 is respectively connected to the two buffer plates 9; the other end of the first transmission rod 5 is provided with two first action surfaces, and the other ends of the two second transmission rods 4 are both provided with second action surfaces. The side surfaces of the two second transmission rods 4 are both provided with first springs, and the inner sides of the two second grooves 3 are provided with first grooves. The first springs are respectively located in the corresponding first grooves, and the first springs are used to drive the buffer plate 9 to move.

[0035] In the original state, the transmission structure is as follows Figure 2 As shown, under the action of the first spring and the second spring, there is a certain distance between the buffer platform 6 and the moving platform 1, one end of the two second transmission rods 4 is located in the first groove, and the two buffer plates 9 are also located in the two second grooves respectively.

[0036] When the buffer platform 6 is hit, Figure 3 As shown, the buffer table 6 moves toward the direction close to the moving table 1. When moving, it drives the first transmission rod 5 to move toward the direction close to the bottom of the first groove. When moving, the two first action surfaces on the first transmission rod 5 act on the second action surfaces of the two second transmission rods 4 respectively, so that the two second transmission rods 4 move respectively in the direction away from the moving table 1, thereby protecting the two sides of the moving table. At this time, the first spring and the second spring are both in a compressed state.

[0037] When there is no external force, the first spring and the second spring return to their original state, thereby driving the first transmission rod 5 to move away from the bottom of the first groove, and the two second transmission rods 4 to move towards the direction close to the moving platform 1. Figure 2 Original condition shown.

[0038] Example 3

[0039] On the basis of the above embodiment, an arc-shaped spring piece 8 is arranged between the transmission structure and the buffer plate 9, and the arc-shaped spring piece 8 is an inwardly concave arc shape; under the action of external force, the arc-shaped spring piece 8 can change from an inwardly concave arc shape to an outwardly convex arc shape.

[0040] The two buffer plates 9 are of the same shape as the arc-shaped spring piece 8, and the arc-shaped spring piece 8 and the buffer plate 9 are in contact with each other; the arc-shaped spring piece 8 is connected to one end of the second transmission rod 4. When the second transmission rod 4 moves in the second groove 3, the second transmission rod 4 moves in a direction away from the bottom of the second groove, that is, the buffer plates 9 move in a direction away from the side of the moving platform 1, and the arc-shaped spring piece 8 changes into an outwardly convex arc shape under the action of the second transmission rod 4. When the second transmission rod 4 moves in a direction close to the bottom of the second groove, the arc-shaped spring piece 8 changes into an inwardly concave arc shape under the action of the second transmission rod 4.

[0041] The arc-shaped spring piece 8 is an elastic spring piece, which can change from an inwardly concave arc shape to an outwardly convex arc shape under the action of an external force, and change from an outwardly convex arc shape to an inwardly concave arc shape under the action of an opposite external force.

[0042] During collision prevention, the arc-shaped spring piece 8 drives the buffer plate 9 to change from an inwardly concave arc shape to an outwardly convex arc shape. The outwardly convex arc shape can better protect the device and improve the use efficiency.
