Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection, and particularly relates to a new type of pipeline protection sleeve for water conservancy projects. Background Technique

[0002] A pipeline protection sleeve is a device or covering specially designed to protect pipelines. Its main functions include preventing physical damage such as bumps, scratches, impacts, etc., avoiding the pipeline from cracking or deforming due to external forces, resisting environmental erosion, for example, resisting the corrosion of chemical substances, the penetration of moisture, the irradiation of ultraviolet rays, etc., extending the service life of the pipeline, heat preservation and insulation, maintaining the temperature of the medium inside the pipeline, reducing heat loss or preventing the influence of external high temperature on the medium inside the pipeline, reducing noise, reducing the noise transmission generated by the fluid flow or vibration inside the pipeline, fire prevention and flame retardancy. In case of a fire, it plays a certain role in fire prevention and prevents the spread of fire. The materials of pipeline protection sleeves are diverse, and common ones include rubber, polyethylene, polyvinyl chloride, stainless steel, aluminum foil, glass fiber, rock wool, etc. Their shapes and sizes are customized according to the specifications and shapes of the pipelines.

[0003] The existing pipeline protection sleeves for water conservancy projects protect the pipelines and prevent their surfaces from being corroded and leaking. However, due to the unstable structure of the existing pipeline protection sleeves for water conservancy construction, it is easy to affect the stability of the pipelines, resulting in pipeline fracture and leakage, which has drawbacks and leads to an increase in the pipeline maintenance workload and relatively high maintenance costs.

[0004] In response to the above problems, the existing patent (Publication No.: CN218564761U), a new type of pipeline protection sleeve for water conservancy projects, by setting rubber pads, tightly fitting the rubber pads on both sides with the outer surface of the pipeline, thus avoiding direct contact between the pipeline and the outside world, and further avoiding the pipeline from being corroded. By setting a rotating rod, the contact between the rotating rod and the outer surface of the inclined block reduces the friction between the inner wall of the receiving groove and the inclined surface of the inclined block, thus facilitating the staff to rotate the adjusting threaded cylinder.

[0005] In response to the above problems, the existing patent gives a solution to reinforce and protect the water delivery pipe. However, at the inflection point of the water delivery pipe, because large collisions often occur when the water flow direction changes, it is necessary to further reinforce it. Otherwise, the inflection point will still crack after long-term use, and there will be relatively large noise during the transportation of the water delivery pipe, which will cause a certain degree of noise pollution.

[0006] Therefore, a new type of pipeline protection sleeve for water conservancy projects is proposed. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a new type of protective sleeve for water conservancy project pipelines, which can solve the problems that the inflection points of existing water conveyance pipelines are prone to rupture and instability, and the noise pollution is relatively large.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A new type of protective sleeve for water conservancy project pipelines, including two water conveyance pipelines. A turning pipeline is fixedly connected to the rear side of the front water conveyance pipeline, and a rear water conveyance pipeline is fixedly connected to the left side of the turning pipeline. Anti-noise mechanisms are movably connected to the outer sides of the two water conveyance pipelines, a protective elastic pad is fixedly connected to the outer sides of the anti-noise mechanisms, and a buffer mechanism is movably connected to the outer side of the turning pipeline;

[0009] The buffer mechanism includes a buffer pad, a thick protective pad, an arch support, an arch frame reinforcement beam and an elastic block. The buffer pad is movably connected to the outer side of the turning pipeline, the arch support is fixedly connected to the right side of the outer side of the buffer pad, the arch frame reinforcement beam is fixedly connected to the inner side of the arch support, the elastic block is fixedly connected to the left side of the outer side of the buffer pad, and the thick protective pad is fixedly connected to the outer sides of the elastic block and the arch support.

[0010] Preferably, a sound-absorbing pad is fixedly connected to the outer side of the water conveyance pipeline, and a first sound-dispersing opening is formed in the inner side of the sound-absorbing pad.

[0011] Preferably, an air layer pad is fixedly connected to the outer side of the sound-absorbing pad, and a support frame is fixedly connected to the inner side of the air layer pad.

[0012] Preferably, a second sound-dispersing opening is formed in the inner side of the first sound-dispersing opening.

[0013] Preferably, a first card sleeve and a second card sleeve are clamped on the outer sides of the protective elastic pad and the thick protective pad, and bolts are bolted to the inner sides of the first card sleeve and the second card sleeve.

[0014] Preferably, a reinforcing plate is fixedly connected to the outer side of the protective elastic pad, a telescopic roller is fixedly connected to the inner side of the reinforcing plate, and the telescopic roller is arranged at the rear sides of the front first card sleeve and the second card sleeve and at the front sides of the rear first card sleeve and the second card sleeve.

[0015] Preferably, anti-slip pads are fixedly connected to the inner sides of the first card sleeve and the second card sleeve.

[0016] Preferably, a compression spring is fixedly connected to the inner side of the elastic block.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. In this application, an arch support is provided on the right side of the inflection point pipeline. When the moving water in the water conveyance pipeline passes through the inflection point pipeline, it collides with the inflection point and changes its conveyance direction. A buffer surface formed by arranging multiple arch supports on the collision surface further rebounds and alleviates the force absorbed by the buffer pad. Moreover, a thick protective pad is provided at the inflection point, greatly enhancing the protective endurance ability. Secondly, an elastic block is provided on the other side of the impacted surface of the inflection point pipeline, which also has the function of absorbing the remaining shock. When receiving the remaining force, the elastic block will slightly contract and rebound to dissipate the force. In this way, the inflection point pipeline can be effectively reinforced to prevent the problem of the inflection point pipeline cracking caused by the collision of the water flow direction change during long-term use.

[0019] 2. In this application, a sound insulation pad similar to that with a first sound-dissipating opening is provided on the outer side of the water conveyance pipeline, forming a resonance relationship with the air layer pad at the rear. When the noise frequency is nearly consistent with the resonance relationship frequency, the energy of the sound wave will be converted into other forms of energy for noise reduction. Secondly, a second sound-dissipating opening is provided inside the first sound-dissipating opening. By opening multiple second sound-dissipating openings, the volatilized noise is further finely converted, making it reverberate back and forth in multiple first sound-dissipating openings and second sound-dissipating openings, making it easier to enter the resonance frequency. In this way, the noise can be reduced to prevent noise pollution. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0029] A new type of pipeline protection sleeve for water conservancy projects includes two water conveyance pipelines 1. The rear side of the front water conveyance pipeline 1 is fixedly connected with an inflection point pipeline 2. The left side of the inflection point pipeline 2 is fixedly connected with the rear water conveyance pipeline 1. A noise prevention mechanism 3 is movably connected to the outer sides of the two water conveyance pipelines 1. A protective elastic pad 4 is fixedly connected to the outer side of the noise prevention mechanism 3. A buffer mechanism 5 is movably connected to the outer side of the inflection point pipeline 2;

[0030] The buffer mechanism 5 includes a buffer pad 51, a thick protective pad 52, an arch support 53, an arch support reinforcement beam 54 and an elastic block 55. The buffer pad 51 is movably connected to the outer side of the inflection point pipeline 2. The arch support 53 is fixedly connected to the right side of the outer side of the buffer pad 51. The arch support reinforcement beam 54 is fixedly connected to the inner side of the arch support 53. The elastic block 55 is fixedly connected to the left side of the outer side of the buffer pad 51. The thick protective pad 52 is fixedly connected to the outer sides of the elastic block 55 and the arch support 53.

[0031] In this embodiment: By arranging a buffer pad 51 on the outer side of the inflection point pipeline 2, a primary energy dissipation can be carried out when the water collides and changes direction during transportation. An arch support 53 is also arranged at the main impact point of the inflection point to divide the received force. The arch support reinforcement beam 54 can make the arch support 53 more stable. Finally, the divided force is transmitted to the outside, and a thick protective pad 52 is arranged on the outside, which has higher tolerance and is more stable than a general protective pad. Secondly, an elastic block 55 is arranged on the other side of the impact surface to eliminate the resonance remaining force generated by the impact. The elastic block 55 disperses the collision remaining force by slightly tightening and expanding after being stressed.

[0032] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 , a sound insulation pad 31 is fixedly connected to the outer side of the water conveyance pipeline 1, and a first sound-dispersing opening 32 is formed in the inner side of the sound insulation pad 31.

[0033] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 , an air layer pad 33 is fixedly connected to the outer side of the sound insulation pad 31, and a support frame 34 is fixedly connected to the inner side of the air layer pad 33.

[0034] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 , a second sound-dispersing opening 35 is formed in the inner side of the first sound-dispersing opening 32.

[0035] In this embodiment: By arranging a sound insulation pad 31 with a first sound-dispersing opening 32 on the outer side of the water conveyance pipeline 1 to form a resonance relationship with the air layer pad 33 at the rear side, when the noise frequency is nearly consistent with the frequency of the resonance relationship, the energy of the sound wave will be converted into other forms of energy for noise reduction. Secondly, a second sound-dispersing opening 35 is formed in the inner side of the first sound-dispersing opening 32. By arranging a plurality of second sound-dispersing openings 35, the volatilized noise is further finely converted, so that it reverberates back and forth in a plurality of first sound-dispersing openings 32 and second sound-dispersing openings 35, making it easier to enter the resonance frequency.

[0036] Specifically, as shown in Figure 1 , Figure 2 , Figure 5 , a first retaining sleeve 6 and a second retaining sleeve 7 are clamped on the outer sides of the protective elastic pad 4 and the thick protective pad 52, and bolts 8 are bolted to the inner sides of the first retaining sleeve 6 and the second retaining sleeve 7.

[0037] Specifically, as shown in Figure 1 , Figure 2 , Figure 5 , a reinforcing plate 9 is fixedly connected to the outer side of the protective elastic pad 4, and a telescopic roller 10 is fixedly connected to the inner side of the reinforcing plate 9. The telescopic roller 10 is arranged at the rear sides of the front first retaining sleeve 6 and the second retaining sleeve 7 and at the front sides of the rear first retaining sleeve 6 and the second retaining sleeve 7.

[0038] In this embodiment: By arranging the first retaining sleeve 6 and the second retaining sleeve 7 and clamping them on the outer sides of the protective elastic pad 4 and the thick protective pad 52 through the bolts 8, clamping and limiting are performed on them. Among them, the protective elastic pad 4 is made of a relatively soft material and is prone to wrinkling. By applying force to the front and rear closed first retaining sleeve 6 and second retaining sleeve 7 through the telescopic roller 10 on the reinforcing plate 9, stretching is performed on the front and rear sides, and the surface of the protective elastic pad 4 is tensioned.

[0039] Specifically, as shown inFigure 1 , Figure 5 , Figure 6 As shown in Figure 6 , anti-slip pads 11 are fixedly connected to the inner sides of the first ferrule 6 and the second ferrule 7 respectively.

[0040] Specifically, as Figure 1 , Figure 5 , Figure 6 shown, a compression spring 12 is fixedly connected to the inner side of the elastic block 55.

[0041] In this embodiment: By setting the anti-slip pads 11, the first ferrule 6 and the second ferrule 7 can be more firmly clamped outside the protective elastic pad 4, and by setting the compression spring 12, the elastic block 55 can be more easily deflected and the pressure on the elastic block 55 can be reduced.

[0042] Working principle: Before installing the protective elastic pad 4 and the thick protective pad 52, the first ferrule 6 and the second ferrule 7 are clamped outside the protective elastic pad 4 and the thick protective pad 52 by bolts 8 for clamping and limiting. The protective elastic pad 4 is made of a relatively soft material and is prone to wrinkles. The telescopic rollers 10 on the reinforcement plate 9 apply force to the first ferrule 6 and the second ferrule 7 that are closed on the front and rear sides, so that they stretch the front and rear sides, and tension the surface of the protective elastic pad 4. When water is transported in the water conveyance pipe 1 and enters the inflection pipe to change the direction, a buffer pad 51 is arranged outside the inflection pipe 2, which can dissipate the force once when the transported water collides and changes the direction. An arch support 53 is also arranged at the main impact point of the inflection point to divide the received force. The arch support reinforcement beam 54 can make the arch support 53 more stable, and finally transmit the divided force to the outside. A thick protective pad 52 is arranged on the outside, which has higher tolerance and is more stable than a general protective pad. Secondly, an elastic block 55 is arranged on the other side of the impact surface to eliminate the resonance remaining force generated by the impact. The elastic block 55 disperses the collision remaining force by slightly tightening and opening after being stressed. And when the water conveyance pipe conveys water, a sound-absorbing pad 31 similar to the one with the first sound-dissipating opening 32 is arranged outside the water conveyance pipe 1, forming a resonance relationship with the air layer pad 33 at the rear. When the noise frequency is almost the same as the resonance relationship frequency, the energy of the sound wave will be converted into other forms of energy for noise reduction. Secondly, a second sound-dissipating opening 35 is opened inside the first sound-dissipating opening 32. By opening a plurality of second sound-dissipating openings 35, the volatilized noise is further finely converted, making it reverberate back and forth in a plurality of first sound-dissipating openings 32 and second sound-dissipating openings 35, making it easier to enter the resonance frequency, and finally completing the reinforcement and noise reduction of the water conveyance pipe 1.

[0043] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
