Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1 to 5 As shown, this embodiment provides an angle adjustment device for adjusting the water inlet angle of pipe 100, ensuring the accuracy of the water inlet angle of pipe 100, expanding the adjustable range of the water inlet angle of pipe 100, and making it applicable to various pipe 100 laying situations, thus expanding the versatility of the angle adjustment device.

[0040] See Figure 1 and Figure 2 The angle adjustment device includes a base 1 and multiple height adjustment components 2, which can be adjusted along the water inlet direction of the pipe 100. Figure 1The height adjusting members 2 are arranged at intervals in the X direction of the base 1, and the pipeline 100 can be movably placed on the height adjusting members 2 in the water inlet direction. The height adjusting members 2 are made of flexible material and have a variable volume air cavity 21 formed therein. The height adjusting members 2 are provided with air vents (not shown in the figure) in communication with the air cavity 21, through which air can be introduced into or discharged from the air cavity 21.

[0041] When air is introduced into or discharged from the air cavity 21 through the air vents, the amount of gas in the air cavity 21 changes, causing the volume of the air cavity 21 to change, and in turn, the height of the height adjusting members 2 made of flexible material also changes. The pipeline 100 is placed on the top of the height adjusting members 2, and by changing the height of each height adjusting member 2, the distance between each part of the pipeline 100 and the base 1 can be changed, thereby adjusting the water inlet angle of the pipeline 100. In the above adjustment process, the height of the height adjusting members 2 is changed by changing the amount of gas in the air cavity 21, so that the height adjusting members 2 can be adjusted to any height, improving the accuracy of the height of the height adjusting members 2 and ensuring the accuracy of the water inlet angle of the pipeline 100. Moreover, the height of each height adjusting member 2 can be adjusted individually, and the range of deformation of the height adjusting members 2 is large, so that the range of adjustment of the water inlet angle of the pipeline 100 is also large, to adapt to various pipeline 100 laying situations, and to expand the versatility of the angle adjusting device.

[0042] For example, the height adjusting members 2 are air bags made of rubber, and the air vents are arranged at the bottom of the height adjusting members 2 to maximize the effective volume of the air cavity 21 and improve the range of height adjustment of the height adjusting members 2.

[0043] Alternatively, referring to Figure 1 and Figure 3, any two adjacent height adjusting members 2 are provided with a first gas conveying pipe 31 and a second gas conveying pipe 32, the first gas conveying pipe 31 and the second gas conveying pipe 32 are in communication with the corresponding gas containing cavities 21, the first gas conveying pipe 31 is provided with a first one-way control valve 33, the gas in the gas containing cavity 21 at the first end of the first gas conveying pipe 31 can enter the gas containing cavity 21 at the second end of the first gas conveying pipe 31 through the first gas conveying pipe 31, the second gas conveying pipe 32 is provided with a second one-way control valve 34, the gas in the gas containing cavity 21 at the second end of the first gas conveying pipe 31 can enter the gas containing cavity 21 at the first end of the first gas conveying pipe 31 through the second gas conveying pipe 32. Wherein, the first end and the second end are two ends of the first gas conveying pipe 31 along the water inlet direction. The setting of the first one-way control valve 33 makes the gas only be able to be conveyed from the first end of the first gas conveying pipe 31 to the second end of the first gas conveying pipe 31, the setting of the second one-way control valve 34 makes the gas only be able to be conveyed from the second end of the first gas conveying pipe 31 to the first end of the first gas conveying pipe 31, that is, the gas can be transmitted directionally and quantitatively between any two adjacent height adjusting members 2, that is, even under the condition that the gas containing cavity 21 is not inflated or deflated, the worker can also individually and accurately adjust the height of the height adjusting member 2 according to the actual demand, which improves the flexibility of the pipeline 100 water inlet angle adjustment and the diversity of the adjustment mode, facilitates the worker to select the appropriate adjustment mode according to the specific construction site, so as to be suitable for the adjustment of the pipeline 100 water inlet angle under various conditions, and expands the universality of the angle adjustment device.

[0044] Specifically, referring to the position in Figure 2 , the pipeline 100 moves into the water from left to right, under the premise that the gas is not injected into the gas containing cavity 21 through the air vent or the gas in the gas containing cavity 21 is not discharged, if the worker wants to reduce the water inlet angle of the pipeline 100, the first one-way control valve 33 can be opened, by extruding the gas containing cavity 21 of the height adjusting member 2 at the left end, the gas in the gas containing cavity 21 can be extruded into the gas containing cavity 21 of the height adjusting member 2 at the right end through the first gas conveying pipe 31, at this time, the height of the height adjusting member 2 at the left end is reduced, the height of the height adjusting member 2 at the right end is increased, the height difference between the two adjacent height adjusting members 2 is reduced, the water inlet angle of the pipeline 100 is reduced, and the pipeline 100 can enter the water more gently, which can be suitable for the laying of the pipeline 100 in shallow water; if the worker wants to increase the water inlet angle of the pipeline 100, the second one-way control valve 34 can be opened, by extruding the gas containing cavity 21 of the height adjusting member 2 at the right end, the gas in the gas containing cavity 21 can be extruded into the gas containing cavity 21 of the height adjusting member 2 at the left end through the second gas conveying pipe 32, at this time, the height of the height adjusting member 2 at the right end is reduced, the height of the height adjusting member 2 at the left end is increased, the height difference between the two adjacent height adjusting members 2 is increased, the water inlet angle of the pipeline 100 is increased, and the pipeline 100 can enter the water more obliquely, which can be suitable for the laying of the pipeline 100 in deep water.

[0045] Exemplarily, the first one-way control valve 33 and the second one-way control valve 34 are both one-way valves.

[0046] In the embodiment, referring to Figure 1 , the first gas conveying pipe 31 and the second gas conveying pipe 32 are both located at the bottom of the height adjusting member 2, so that the gas in the gas containing cavity 21 can be completely discharged.

[0047] Optionally, referring to Figure 1 and Figure 2 , the angle adjusting device further comprises an elastic support 4 located in the gas containing cavity 21, one end of the elastic support 4 is connected with the upper cavity wall of the gas containing cavity 21, the other end of the elastic support 4 is connected with the lower cavity wall of the gas containing cavity 21, and the extension length of the elastic support 4 is adjustable. When the volume of the gas containing cavity 21, i.e. the height of the height adjusting member 2, changes, the extension length of the elastic support 4 changes accordingly, and the elastic support 4 accumulates elastic potential energy; when the height adjusting member 2 moves to the required height, the elastic support 4 is fixed at the current length, which can provide stable support for the height adjusting member 2, so that the height adjusting member 2 can be kept at the current height, preventing the height adjusting member 2 from being deformed under the gravity of the pipeline 100 and affecting the angle of the pipeline 100 entering the water; when the angle of the pipeline 100 entering the water needs to be adjusted again, the gas is discharged from the gas containing cavity 21 at the same time, and the elastic support 4 releases the accumulated elastic potential energy, so that the elastic support 4 can quickly return to the position before the height adjustment, which helps to improve the efficiency of the angle adjustment of the pipeline 100 entering the water.

[0048] Specifically, referring to Figure 1 , the elastic support 4 comprises a telescopic rod 41 and an elastic member 42, the telescopic rod 41 is connected with the cavity wall of the gas containing cavity 21, and the elastic member 42 is sleeved on the telescopic rod 41. When the gas is filled into or discharged from the gas containing cavity 21, the height of the height adjusting member 2 changes, driving the telescopic rod 41 to elongate or shorten, and the elastic member 42 deforms, generating elastic force. When the amount of gas in the gas containing cavity 21 changes, the generated elastic force makes the pipeline 100 and the height adjusting member have a certain buffering effect, so as to avoid damage to the pipeline 100 caused by impact.

[0049] Exemplarily, the elastic member 42 is a spring.

[0050] Further, referring to Figure 1 , a plurality of elastic supports 4 are arranged in the gas containing cavity 21 to stably support the height adjusting member 2.

[0052] Optionally, referring to Figure 1 and Figure 4 , the angle adjusting device further comprises a plurality of first flexible supporting members 5, which correspond to the plurality of height adjusting members 2 one by one, and the first flexible supporting members 5 are arranged on the top of the corresponding height adjusting members 2 and used for supporting the pipeline 100. When the pipeline 100 is placed on the first flexible supporting members 5, the first flexible supporting members 5 can be in flexible contact with the pipeline 100 to prevent the pipeline 100 from being damaged by knocking, and the first flexible supporting members 5 can also be more closely attached to the pipeline 100 to improve the stability and safety of the pipeline 100 placed thereon and provide better support effect for the pipeline 100.

[0053] Exemplarily, the first flexible supporting members 5 are made of rubber and can withstand large deformation without being damaged.

[0054] In this embodiment, referring to Figure 4 , the top of the first flexible supporting member 5 is provided with an arc-shaped supporting groove 51, and the pipeline 100 can be embedded in the arc-shaped supporting groove 51. The arrangement of the arc-shaped supporting groove 51 enables the pipe wall of the pipeline 100 to be better attached to the first flexible supporting member 5, thereby providing more stable supporting effect for the pipeline 100; and the arc-shaped supporting groove 51 can also limit the movement of the pipeline 100 on the first flexible supporting member 5 along a preset direction (Y direction in the figure), so that the pipeline 100 can only move in the water inlet direction, thereby ensuring the accuracy of laying of the pipeline 100. Figure 4

[0055] Exemplarily, referring to Figure 4 , the cross-sectional shape of the pipeline 100 is circular, and the cross-sectional shape of the arc-shaped supporting groove 51 is semicircular.

When the pipeline 100 moves in the water inlet direction or needs to adjust the position of the pipeline 100 in the arc-shaped supporting groove 51, the balls 52 roll, which can effectively reduce the friction between the groove wall of the arc-shaped supporting groove 51 and the pipe wall of the pipeline 100, so that the movement of the pipeline 100 is more smooth, facilitating the movement of the pipeline 100, and also reducing the degree of wear on the surface of the pipeline 100. ​

[0057] Specifically, the inner wall of the arc-shaped supporting groove 51 is provided with a ball groove extending along the bending direction thereof, and the ball 52 is rollably arranged in the ball groove and partially protrudes from the groove wall of the arc-shaped supporting groove 51, so that the ball 52 can contact and rotate relative to the outer wall of the pipeline 100.

Exemplarily, the lubricant is lubricating oil.

The protective pieces 6 are in contact with the side wall of the height adjusting piece 2, which can limit the deformation of the height adjusting piece 2 along the preset direction, so as to constrain the deformation direction of the height adjusting piece 2, so that the height adjusting piece 2 can only deform along the vertical direction, thereby ensuring the accuracy of the adjustment of the water inlet pipeline 100; at the same time, the protective pieces 6 can provide protection for the height adjusting piece 2, so as to prevent the height adjusting piece 2 and the pipeline 100 from being damaged by accidental impact of external objects during work on water, thereby improving the safety of the construction site.

[0060] Exemplarily, referring to Figure 1 , the protective pieces 6 are protective plates, and the height of the protective pieces 6 along the vertical direction (Z direction in Figure 1 ) is greater than the height of the highest end of the pipeline 100, so as to ensure the protection effect of the height adjusting piece 2 and the pipeline 100.

[0061] Optionally, referring to Figure 1 , the angle adjusting device further comprises a second flexible supporting piece 7 arranged on the base 1, and the second flexible supporting piece 7 is used for supporting the lowest end of the pipeline 100, so as to prevent the lowest end of the pipeline 100 from being in hard contact with the base 1, thereby preventing the pipeline 100 from being abraded and affecting the service life of the pipeline 100.

[0064] Specifically, when the sealing cover 8 is connected with the height adjusting member 2, the air vent is plugged, and when the sealing cover 8 is detached from the height adjusting member 2, the air vent is unplugged.

[0065] Exemplarily, the sealing cover 8 is threadedly connected with the height adjusting member 2, the threaded connection has strong tightness, so that the connection parts of the sealing cover 8 and the height adjusting member 2 can be engaged with each other, and gas leakage can be effectively prevented.
