Description

Technical Field

[0001] The utility model relates to the technical field of deep-water cofferdam construction for bridges, and in particular to an installation device for an intelligent monitoring system for deep-water cofferdam sinking construction. Background Art

[0002] In the deep-water cofferdam sinking operation, some sensors need to be installed underwater after the cofferdam sinks to the predetermined position. This is mainly because the installation position or installation conditions of these sensors need to be determined or met after the cofferdam is stable. For example, the water level sensor is used to monitor the water level changes inside and outside the cofferdam. Since the water level may change after the cofferdam sinks, it is necessary to install the water level sensor after the cofferdam is stable to ensure its accurate measurement. At present, the installation of water level sensors requires workers to wear diving suits and dive underwater for operations. Subsequent maintenance and replacement of sensors also require underwater operations. During the installation process, a large number of professional tools and auxiliary tools are involved, resulting in low efficiency of underwater operations and certain safety hazards.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 8As shown, the present embodiment provides an installation device for an intelligent monitoring system for deepwater cofferdam sinking construction, comprising a bracket 1, a protective tube 2 and a tube fixing assembly, wherein the bracket 1 is prefabricated on the side wall of the cofferdam, and a plurality of brackets 1 are sequentially arranged from top to bottom, the protective tube 2 is used to install a sensor, and a probe of the sensor is fixed to the bottom end of the protective tube 2 and extends from the bottom end of the protective tube 2, the cable of the sensor is located in the protective tube 2 and the tail end of the cable extends from the top end of the protective tube 2, and the tube fixing assembly comprises an operating rod 3 and two semicircular fixing plates 4 which are arranged opposite to each other on each bracket 1, and the operating rod 3 is used to control the opening and closing of the two semicircular fixing plates 4 on all brackets 1.

[0028] Before the deepwater cofferdam is sunk, the bracket 1 and the pipe fixing assembly are pre-installed on the side wall of the deepwater cofferdam. After the deepwater cofferdam is sunk and stabilized, when installing the water level sensor, the probe of the water level sensor is directly fixed to the bottom end of the protective tube 2, and the cable is passed through the protective tube 2 and extended from the top. Observe the state of the operating rod 3, and use the operating rod 3 to make the two semicircular fixing pieces 4 on the bracket 1 open, and then the protective tube 2 passes through all the brackets 1 in sequence with the probe facing downward. In the process of passing down, the protective tube 2 passes between the two semicircular fixing pieces 4 on the bracket 1 in an open state. The semicircular fixing piece 4 can not only guide the protective tube 2 to pass through in the preset state, but also limit the protective tube 2 to prevent the probe from being pulled and transitionally bent under the action of the water flow on the pile foundation deepwater cofferdam. When the protective tube 2 passes down to the specified depth, the semicircular fixing piece 4 is used to fix the protective tube 2 by the operating rod 3, and the installation of the water level sensor is completed. During the entire installation process of the water level sensor, the operator only needs to stand on the top edge of the deep water cofferdam to operate, without having to go into the water, which is safer and more efficient. In the subsequent replacement or maintenance process of the sensor in the event of a fault, there is no need to go into the water. All that is needed is to use the operating lever 3 to adjust the semicircular fixing pieces 4 in all the pipe fixing components to the open state, and then pull out the protective tube 2 as a whole to replace or repair the sensor.

[0029] The bracket 1 is in a "π"-shaped structure, with two semicircular fixing pieces 4 located on both sides of the inner cavity of the bracket 1, and a slide groove 5 is provided at the inner end of the semicircular fixing piece 4, and sliders 6 are provided on both sides of the inner surface of the bracket 1, and the slide groove 5 is sleeved on the slider 6. A threaded hole 7 is provided at the inner end of the semicircular fixing piece 4, and a threaded column 8 is threaded through the inner thread of the threaded hole 7. The outer end of the threaded column 8 is rotatably connected to the inner wall of the bracket 1, and the thread directions of the two threaded columns 8 in the bracket 1 are opposite. The operating rod 3 controls the opening and closing of the semicircular fixing piece 4 by driving the threaded column 8 to rotate.

[0030] The cooperation between the slide groove 5 and the slider 6 realizes the sliding cooperation between the semicircular fixing plate 4 and the bracket 1. The cooperation between the threaded column 8 and the threaded hole 7 not only stably installs the semicircular fixing plate 4 on the bracket 1, but also utilizes the rotation of the threaded column 8 to control the semicircular fixing plate 4 to switch between the open and merged states.

[0031] The opposite ends of the two threaded columns 8 are connected to a driving rod 9, and a circle of tooth grooves 10 are provided on the circumferential surface of the driving rod 9. The side of the operating rod 3 is provided with a rack 11 meshing with the tooth grooves 10. At this time, the driving rod 9 can be rotated through the rack 11 and the tooth groove 10 by controlling the up and down displacement of the operating rod 3. The driving rod 9 can realize the opening or merging of the semicircular fixing plate 4 by controlling the rotation of the threaded column 8.

[0032] An annular groove 12 is provided on the surface of the driving rod 9, and the tooth groove 10 is provided on the inner surface of the annular groove 12. The rack 11 is slidably restricted in the annular groove 12, and the operating rod 3 is slidably sleeved in the bracket 1. At this time, the annular groove 12 cooperates with the bracket 1 to sleeve the operating rod 3 and the rack 11 as a whole, so as to achieve the effect of stabilizing the operating rod 3.

[0033] The top of the operating rod 3 is rotatably mounted with a lead screw 13, and the external thread sleeve of the lead screw 13 is provided with a thread sleeve 14, and the thread sleeve 14 is fixedly mounted on a mounting frame 15, and the mounting frame 15 is used to be fixed on the side wall of the cofferdam, and the upper and lower ends of the thread sleeve 14 are provided with locking nuts 16 threadedly sleeved outside the lead screw 13. Specifically, the lead screw can be rotated by loosening the two locking nuts 16, and the lead screw can control the lifting and lowering movement of the operating rod 3 by moving up and down in the thread sleeve 14, and thereby directly control the opening or merging of all the semicircular fixing plates 4, and then, the locking nut 16 is screwed in to further fix the lead screw 13, which can improve the locking effect and stability of the operating rod 3.

[0034] The top of the semicircular fixing plate is provided with a conical guide plate 17 with an outwardly expanded top end. The conical guide plate 17 has a guiding function when the protection tube 2 is passed down, so that the bottom end of the protection tube 2 is inserted into the semicircular fixing plate 4 from top to bottom.

[0035] The surface of the protection tube 2 is provided with a limiting plate 18 which is relatively distributed inside and outside. The limiting plate 18 is staggered with the tube fixing assembly in the length direction of the protection tube 2, and the thickness of the limiting plate 18 is set to match the width of the channel 19 formed when the two semicircular fixing pieces 4 on the bracket 1 are opened. In the process of passing through or pulling up the protection tube 2, the limiting plate 18 moves in the channel 19, so that the accuracy of passing through is guaranteed by the limiting plate 18. At the same time, the cooperation between the limiting plate 18 and the channel 19 can prevent the protection tube 2 from shaking between the semicircular fixing pieces 4, so as to better protect the probe and the protection tube 2.

[0036] Of the two semicircular fixing plates 4 on the bracket 1, baffles 20 are provided on the outer end of one of the semicircular fixing plates 4 and the inner side of the other fixing plate, and the two baffles 20 respectively block the two channels 19. In the process of passing through or pulling up the protection tube 2, the baffle 20 limits the position of the limit plate 18, so that the protection tube 2 will not shake in and out of the semicircular fixing plate 4 in a direction perpendicular to the bracket 1, and further better protect the probe and the protection tube 2.

[0037] The outside of the protective tube 2 is fixed with an external screw sleeve 21 corresponding to each bracket 1, and the inner surfaces of the two semicircular fixing plates 4 in the bracket 1 are set as threaded surfaces, and when the two semicircular fixing plates 4 are in a combined state, the threads of the two threaded surfaces are connected and adapted to the threads on the surface of the external screw sleeve 21.

[0038] When the protection tube 2 is passed down to the specified depth, the limit plates 18 and the bracket 1 are in a staggered distribution state in the length direction of the protection tube 2. At this time, the outer screw sleeve 21 and the tube fixing assembly are in a one-to-one correspondence state, and the outer screw sleeve 21 is located above the two corresponding semicircular fixing pieces 4 in the height direction. After all the semicircular fixing pieces 4 are merged by the operating rod 3, the inner surfaces of the two semicircular fixing pieces 4 located on the same bracket 1 are complete threaded surfaces. At this time, the threaded fit between the outer screw sleeve 21 and the threaded surface can be used to more effectively fix the protection tube 2 using the tube fixing assembly, thereby improving the fixing effect.

[0039] The top end of the outer screw sleeve 21 is arranged in a conical structure parallel to the generatrix of the conical guide plate 17, and when the outer screw sleeve 21 is completely threadedly connected with the semicircular fixing plate 4, the top end of the outer side surface of the outer screw sleeve 21 contacts the bottom end of the inner side surface of the conical guide plate 17. When the protection tube 2 is rotated so that the outer screw sleeve 21 is threadedly matched with the threaded surfaces of the two semicircular fixing plates 4, the protection tube 2 is displaced downward until the outer screw sleeve 21 completely enters the semicircular fixing plate 4, and the top end of the outer screw sleeve 21 is limited by the conical guide plate 17.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
