Description

Technical Field

[0001] The utility model relates to the technical field of engineering, in particular to a protective device for underground pipeline diving operations. Background Art

[0002] Underground pipelines carry key functions such as water supply, drainage, gas, and heat in cities. Their integrity and stability are directly related to the normal operation of cities and the quality of life of residents. However, due to the long-term underground presence of underground pipelines, they are affected by soil corrosion, water erosion, pressure changes and other factors. The pipelines themselves and their ancillary facilities are prone to aging, damage, blockage and other problems. Therefore, divers are usually required to perform maintenance inside the pipelines.

[0003] Generally, divers wear protective clothing and masks and enter the sewer pipes directly for work. However, because the underground pipe environment is usually narrow, dim, and full of unknown factors, divers are easily hit by obstacles inside the pipes during work. If they only wear protective clothing and masks, they are likely to be inadequately protected.

[0004] Therefore, a protective device for underground pipeline diving operations is needed to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a protective device for underground pipeline diving operations, such as Figure 1-Figure 4As shown, the protective device includes a fixed block 1, connecting rings 2 symmetrically hinged on both sides of the fixed block 1, a buffer component 3 arranged at the bottom of the fixed block 1 for protective buffering, and a hip protective plate 4 arranged on the side of the buffer component 3 away from the fixed block 1 for hip protection; a locking component 22 for connecting the two connecting rings 2 is arranged at one end of the two connecting rings 2 away from the fixed block 1.

[0028] When in use, first release the connection between the two connecting rings 2 by the locking assembly 22. At this time, since the two connecting rings 2 are respectively hinged to the two sides of the connecting ring 2, when the diver puts on the protective suit, the connecting ring 2 can be opened and put around the waist, and then the two connecting rings 2 are locked by the locking assembly 22, so that the fixed block 1 and the connecting ring 2 are fixed at the waist. When the diver enters the sewer for maintenance work, at this time, under the wearing effect of the fixed block 1 and the two connecting rings 2, the waist of the diver can be protected. At the same time, when the diver enters the sewer or completely enters the sewer, when the hip protective plate 4 is hit by garbage or stones in the sewer, the buffer assembly 3 will promptly reduce the impact force on the hip protective plate 4 to protect the diver's buttocks.

[0029] Specifically, the locking assembly 22 includes a first sleeve 221 and a second sleeve 222 respectively screwed on one end of the two connecting rings 2 away from the fixing block 1, a slot opened at one end of the second sleeve 222 close to the first sleeve 221, an insert block 223 fixedly mounted on the first sleeve 221 and plugged into the slot, and a locking bolt 224 screwed on one side of the second sleeve 222 and abutting against the insert block 223; when it is necessary to unlock the connection between the two connecting rings 2, the operator only needs to rotate the locking bolt 224 to release the abutment of the locking bolt 224 on the insert block 223, and then pull the first sleeve 221 to disengage the insert block 223 on the first sleeve 221 from the slot on the second sleeve 222, so that the two connecting rings 2 can be easily opened. When it is necessary to lock the two connecting rings 2, the operator only needs to insert the insert block 223 into the slot and tighten the locking bolt 224 to connect the two connecting rings 2.

[0030] Among them, in order to improve the flexibility of use of the protective device, a receiving groove 21 is opened in the connecting ring 2; when using the protective device, the first sleeve 221 or the second sleeve 222 can be rotated according to the operator's own weight to release the connection between the first sleeve 221 or the second sleeve 222 and the corresponding connecting ring 2, and then fill the receiving groove 21 with lead blocks, so as to realize the adjustment of the gravity of the protective device, so as to be suitable for the adjustment of the buoyancy of operators of different weights when entering the water.

[0031] In addition, in order to further facilitate wearing, a wearing belt 23 is fixedly installed on the connecting ring 2; the user only needs to put the wearing belt 23 on the shoulders to easily fix the protective device on the body without complicated operating steps or additional fixing tools.

[0032] Furthermore, the buffer assembly 3 includes a fixed rod 31 fixedly installed at the bottom of the fixed block 1, a telescopic rod 32 slidably installed at one end of the fixed rod 31 away from the fixed block 1 and fixedly connected to the hip protective plate 4, and a buffer spring 33 sleeved on the telescopic rod 32, and the two ends of the buffer spring 33 are respectively fixedly connected to the inner wall of the fixed rod 31 and the telescopic rod 32; when the diver enters the sewer and his hip protective plate 4 is hit by garbage or stones in the sewer, the telescopic rod 32 connected to the hip protective plate 4 will longitudinally telescope and slide in the fixed rod 31 under the elastic deformation of the buffer spring 33, so as to achieve buffering of the impact force of the hip protective plate 4, thereby improving the protection of the diver.

[0033] Furthermore, a lifting ring 11 is fixedly installed on the top of the fixed block 1; when the diver wears the protective device, the operator on the ground can connect the lifting rope to the lifting ring 11 on the fixed block 1. When an emergency occurs, the operator on the ground can pull the lifting rope to pull the diver out of the sewer pipe, thereby improving the safety of the operation.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
