Under the action of the elastic force of the arc-shaped elastic piece 14, the support seat 5 is fixedly not moved, so that the cabin door 2 can keep closed, which is convenient for storage and transportation. When the cabin door 2 needs to be opened, a downward force is applied to the support seat 5, the guide rod 7 can pass between the two arc-shaped elastic pieces 14 again and be separated from the limiting box 13, so that the cabin door 2 is opened.

[0027] In order to achieve the effect of convenient loading and unloading and carrying, the driving assembly comprises a fixed groove 15 opened on the upper surface of the support base 5, the support rod 16 is detachably connected in the fixed groove 15, and the top end of the support rod 16 extends out of the groove rod 4. When the support base 5 is fixed on the groove rod 4 for limiting, the support rod 16 can be simply and conveniently loaded and unloaded, carrying and transportation are more convenient, and different environmental use requirements can be met.

[0028] In order to achieve the effect that the placing depth of the cabin body 1 can be flexibly adjusted, the number of the support rods 16 is several, the bottom end of the support rod 16 is provided with an external thread opening 17, the top end of the support rod 16 is provided with an internal thread opening 18, the external thread opening 17 is threadedly connected in the fixed groove 15, and the external thread opening 17 of one of the support rods 16 can be threadedly connected in the internal thread opening 18 of another one of the support rods 16. Through cooperation of the external thread opening 17 and the internal thread opening 18, a plurality of support rods 16 can be sequentially installed, so that the cabin body 1 can be placed in the underground cable trench at different depths, and in turn, the retracting and releasing operation of the inspection robot is more flexible, and different use requirements can be met.

Through the hollow treatment of the cabin body 1 and the first through hole 19, the cabin body 1 can be safely and stably placed to reduce the overall weight of the device, and the staff can operate and use more conveniently.

[0030] In order to achieve the effect that the inspection robot can conveniently enter and exit the cabin body 1, the second through hole 20 is arranged on the cabin door 2. Through the second through hole 20, the quality is further reduced, the friction between the inspection robot and the cabin door 2 is increased, and the inspection robot can smoothly enter and exit the cabin body 1.

[0031] In use, during the underground channel inspection operation of the inspection robot, the support rod 16 is installed on the support base 5, then the support rod 16 is moved downward to drive the support base 5 to move downward, the support base 5 stably descends in the groove rod 4 through cooperation of the guide rod 7 and the guide groove 6, the cabin door 2 is opened under the action of its own gravity and through cooperation of the pull rope 8, the first pulley 10, the second pulley 11 and the third pulley 12, the cabin door 2 is opened at the same time as the support rod 16 descends, until the cabin door 2 is completely opened, the inspection robot is placed in the cabin body 1, then a plurality of support rods 16 are sequentially installed according to the use requirement of the underground channel, and the cabin door 2 is closed by lifting the support rod 16 upward.

[0032] Then, the staff holds the support rod 16 to place the cabin body 1 on the bottom surface in the underground channel through the ground entrance, and according to the above principle, the cabin door 2 is opened as the support rod 16 descends, and then the inspection robot is released to perform the inspection operation.

[0033] After the inspection operation is completed, the inspection robot enters the cabin body 1, the worker lifts the support rod 16, along with the rising of the support rod 16, the hatch 2 is closed, when the support base 5 is located on the slot rod 4 upper limit, the hatch 2 is completely closed, then continue to lift the support rod 16, the cabin body 1 together with the inspection robot is retrieved.

[0034] The present application is novel in concept, convenient to operate, and strong in practicality. The worker holds the support rod 16 to retract and release, and the cabin body 1 and the hatch 2 cooperate to safely and stably retract and release the inspection robot. The operation is simple and can avoid damage caused by bumps. The support rod 16 drives the support base 5 to rise or fall, and the hatch 2 can be quickly closed or opened under the cooperation of the pull rope 8, the first pulley 10, the second pulley 11 and the third pulley 12. The retraction and release of the inspection robot is more convenient and efficient. The outer threaded opening 17 and the inner threaded opening 18 cooperate to connect different numbers of support rods 16 according to the use requirements, so that the inspection robot can be placed in underground channels of different depths, avoiding the worker to bend over to place it. The use is more flexible, the safety hazards to the worker are avoided, the work efficiency of the inspection is effectively improved, and the practicality of the use is greatly improved.

[0035] It can be seen that the high-safety retraction and release device for the channel robot can effectively solve the problems of poor safety and low efficiency, high difficulty, low stability and easy damage in the prior art.
