Description

Technical Field

[0001] The invention relates to the technical field of water conservancy surveying and setting out, in particular to a cofferdam surveying and setting out device for water conservancy pump station construction. Background Art

[0002] A hydraulic pumping station refers to a pumping station used in water conservancy projects. It is mainly used to transport, lift and control water. It is usually composed of pumps, generators, control equipment and supporting pipelines. Its main function is to pump water from low places to high places or transport it over long distances to meet the needs of various purposes such as irrigation, urban water supply, and industrial water. Hydraulic pumping stations are usually designed and built according to specific project needs and geographical conditions. Their scale ranges from small rural water supply pumping stations to large urban water supply project pumping stations. During the construction of hydraulic pumping stations, it is usually necessary to measure and lay out the cofferdams, which plays a vital role in the construction of hydraulic pumping stations. It not only affects the construction quality and progress, but is also directly related to the safety and operation effect of the pumping stations.

[0003] In the related art, Chinese patent publication number CN217267572U discloses a cofferdam measurement and line-laying device for water conservancy pump station construction. When in use, it is convenient to wind the measuring line around the rotating shaft, and use the set upright pole body to fix the device on the target ground. The target height of the sleeve fixed pipe clamped on the upright pole body is used to fix the initial position of the measuring line, and then the line-laying operation can be realized through the set rotating shaft, and the end line is tied to the upright pole body at the end position. After the end of the later use, the rotating shaft can be rotated to facilitate the collection of the measuring line. The setting of the gear plate and the gear block can realize the limit of the rotating shaft, making the line-laying and line-recovering operation convenient, so the measuring line is easy to recycle and not easy to get knotted. The device also has the following disadvantages: the upright pole body is an integral structure, and its length is relatively long. When carried and used, the rod body cannot be folded, and it takes up a large space, which is inconvenient to carry. Summary of the invention

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. During use of the present invention, an appropriate number of connecting rods (N) are selected according to needs. The connecting rods are connected one by one through a hinge structure to form a connecting rod assembly. A locking sleeve is sleeved on each hinge structure to ensure that the connecting rod can fit tightly and lock. The winding structure is installed on the top connecting rod to ensure stability and reliability. The fixing seat of the auxiliary fixing structure is installed on the bottom connecting rod to firmly connect the connecting rod to the ground. If folding and storage are required, first loosen all the locking sleeves and fold the connecting rods one by one to reduce the occupied space. If it is necessary to increase or decrease the connecting rods, according to actual needs, the connecting rods can be added or reduced in the middle part of the connecting rod assembly, and the hinge structure and the locking sleeve can be reconnected. In this way, the cofferdam measurement and layout device for water conservancy pump station construction of the present invention realizes efficient, accurate and stable cofferdam measurement and layout functions through the coordinated work of the connecting rod assembly, the locking assembly, the winding structure and the auxiliary fixing structure. The device can be conveniently folded, stored and unfolded according to needs through the connecting rod assembly, and the number of connecting rods can be increased or decreased to adapt to cofferdam measurement and layout work of different scales. The locking function of the locking assembly ensures that the connecting rod can stably maintain an upright state when needed, thereby improving the overall stability of the device.

[0028] 2. When it is necessary to fix the connecting rod assembly, the construction personnel tighten the locking sleeve to the hinge part and the hinge block so that the connecting rods cannot rotate relative to each other, thereby maintaining an upright state and ensuring the stability of the device. When it is necessary to fold or adjust the connecting rod assembly, the construction personnel only need to loosen the locking sleeve, and the connecting rods can freely rotate to a parallel state, which is convenient for carrying and storage. The present invention provides an intermediate connection point through the design of the hinge seat, so that two adjacent connecting rods can rotate around the hinge seat respectively without interfering with each other. Through the hinge seat, two adjacent connecting rods can be easily rotated to a parallel state. In the parallel state, the gap between the connecting rods is smaller, making the entire device more compact.

[0029] 3. The blocking ring of the present invention provides a clear positioning point for the connecting rod, ensuring that the connecting rod can maintain the correct position during assembly and use. The blocking ring serves as the lower limit of the locking sleeve to prevent the locking sleeve from over-pressing the connecting rod during the tightening process, thereby avoiding damage or difficulty in unlocking that may be caused by over-tightening. The blocking ring serves as an obvious reference point, making the installation and removal of the locking sleeve more convenient and quick, without the need for additional measurement or positioning. Through the cooperation of the blocking ring and the locking sleeve, the connection between the connecting rods is more stable and is not easy to loosen or fall off even when subjected to external forces.

[0030] 4. The cable winding structure of the present invention includes a first mounting member, a mounting frame, a winding roller, a rocker and a limiter; when the cable needs to be released or reeled in, the user drives the winding roller to rotate by shaking the rocker. The limiter ensures that the rocker and the winding roller rotate within a set range to prevent excessive rotation. The user can release or reel in the cable by simply shaking the rocker, which is easy and quick to operate. The design of the limiter effectively limits the rotation range of the rocker and the winding roller, enhancing safety during use.

[0031] 5. The various components of the auxiliary fixing structure of the present invention are assembled together in a stable connection manner, ensuring the stability and durability of the overall structure. Driven by the driving member, the slider, the support rod and the mounting rod can move flexibly to achieve auxiliary support for the support column. The auxiliary fixing structure can adjust the support strength and position of the support column according to actual needs, and has strong adaptability. The assembly process is simple and quick. It only needs to put the second mounting sleeve rod and the slider on the connecting rod, and screw the second fixing screw block to complete the installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Please refer to Figure 1-8 As shown, this embodiment provides a cofferdam measurement and laying-out device for water conservancy pump station construction, including: a connecting rod assembly, a locking assembly, a winding structure and an auxiliary fixing structure;

[0046] Specifically, the connecting rod assembly includes N connecting rods and M hinge structures; each two adjacent connecting rods are hinged to each other through a hinge structure, so that M hinge structures are formed between the N connecting rods, wherein N≥2, M=N-1;

[0047] Specifically, the locking assembly includes a plurality of locking sleeves 5, each hinge structure is sleeved with a locking sleeve 5; the locking sleeve 5 is used to lock or unlock the hinge structure, so that the connecting rod is in a locked state or an unlocked state; when the locking sleeve 5 is in an unlocked state, the plurality of connecting rods can rotate between each other, so that the plurality of connecting rods can be folded; when the locking sleeve 5 is in a locked state, the plurality of connecting rods are relatively fixed between each other, so that the plurality of connecting rods are kept in an upright state;

[0048] Specifically, the winding structure is installed on the uppermost connecting rod, and the winding structure is used for releasing or winding the wire;

[0049] Specifically, the auxiliary fixing structure is installed on the lowest connecting rod, and the auxiliary fixing structure is used to be fixed on the ground to provide auxiliary support for the lowest connecting rod.

[0050] On the basis of the above structure, during use, select an appropriate number of connecting rods (N) according to needs. Connect the connecting rods one by one through a hinged structure to form a connecting rod assembly. Sleeve the locking sleeve 5 on each hinged structure to ensure that the connecting rod can fit tightly and lock. Install the winding structure on the top connecting rod to ensure stability and reliability. Install the fixing seat of the auxiliary fixing structure on the bottom connecting rod to firmly connect the connecting rod to the ground. If folding and storage are required, first loosen all the locking sleeves 5, and fold the connecting rods one by one to reduce the occupied space. If you need to add or reduce connecting rods, you can add or reduce connecting rods in the middle part of the connecting rod assembly according to actual needs, and reconnect the hinged structure and the locking sleeve 5. In this way, the cofferdam measurement and layout device for water conservancy pump station construction of the present invention realizes efficient, accurate and stable cofferdam measurement and layout functions through the coordinated work of the connecting rod assembly, the locking assembly, the winding structure and the auxiliary fixing structure. The device can be conveniently folded, stored and unfolded according to needs through the connecting rod assembly, and the number of connecting rods can be increased or decreased to adapt to cofferdam measurement and layout work of different scales. The locking function of the locking assembly ensures that the connecting rod can stably maintain an upright state when needed, thereby improving the overall stability of the device.

[0051] In a preferred embodiment of the present invention, the hinge structure includes a hinge block 4; wherein the topmost connecting rod is denoted as a top rod 1, the bottommost connecting rod is denoted as a bottom rod 3, and the remaining connecting rods are denoted as middle rods 2;

[0052] The lower end of the top rod 1 and the upper end of the bottom rod 3 are respectively provided with hinged parts, both ends of the middle rod 2 are also provided with hinged parts, and both ends of the hinge block 4 are respectively provided with a hinged part;

[0053] The hinged portion of the top rod 1 is hinged to the hinged portion of the upper end of the adjacent connecting rod through a hinged block 4;

[0054] Each of the hinged parts of two adjacent middle rods 2 is hingedly connected via a hinge block 4;

[0055] The hinged portion of the bottom rod 3 is hinged to the hinged portion of the lower end of the adjacent connecting rod via a hinged block 4;

[0056] External threads are provided on the outer walls of the hinge portion and the hinge block 4;

[0057] An internal thread is formed on the inner wall of the locking sleeve 5;

[0058] Each hinge block 4 is threadedly connected to a locking sleeve 5, and each locking sleeve 5 is also threadedly connected to the hinged parts of two adjacent connecting rods.

[0059] On the basis of the above structure, when it is necessary to fix the connecting rod assembly, the construction personnel tighten the locking sleeve 5 to the hinge part and the hinge block 4 so that the connecting rods cannot rotate relative to each other, thereby maintaining an upright state and ensuring the stability of the device. When it is necessary to fold or adjust the connecting rod assembly, the construction personnel only need to loosen the locking sleeve 5, and the connecting rods can freely rotate to a parallel state, which is convenient for carrying and storage. When two connecting rods are directly hinged, their hinge parts will interfere with each other, resulting in an inability to rotate to a parallel state. The present invention provides an intermediate connection point through the design of the hinge seat, so that two adjacent connecting rods can rotate around the hinge seat respectively without interfering with each other. Through the hinge seat, two adjacent connecting rods can be easily rotated to a parallel state. In the parallel state, the gap between the connecting rods is smaller, making the entire device more compact.

[0060] In a preferred embodiment of the present invention, the length of the locking sleeve 5 is greater than the sum of the lengths of the hinge block 4 and the hinged parts of the two adjacent connecting rods; when the locking sleeve 5 is in a locked state, the locking sleeve 5 can completely cover the hinge block 4 and the hinged parts of the two adjacent connecting rods to prevent the external threads from being exposed. This design not only protects the external threads, but also improves the safety, aesthetics and user experience of the device.

[0061] In a preferred embodiment of the present invention, except for the uppermost connecting rod, a blocking ring 6 is provided at the upper end of the middle rod 2 below the external thread, and the locking sleeve 5 is provided above the blocking ring 6 .

[0062] On the basis of the above structure, the blocking ring 6 provides a clear positioning point for the connecting rod, ensuring that the connecting rod can maintain the correct position during assembly and use. The blocking ring 6 serves as the lower limit of the locking sleeve 5 to prevent the locking sleeve 5 from over-pressing the connecting rod during the tightening process, thereby avoiding the problem of damage or difficulty in unlocking that may be caused by over-tightening. The blocking ring 6 serves as an obvious reference point, making the installation and removal of the locking sleeve 5 more convenient and quick, without the need for additional measurement or positioning. Through the cooperation of the blocking ring 6 and the locking sleeve 5, the connection between the connecting rods is more stable and is not easy to loosen or fall off even when subjected to external forces.

[0063] In a preferred embodiment of the present invention, the winding structure includes a first mounting member, a mounting frame 9, a winding roller 10, a rocker 11 and a limiting member. The first mounting member is sleeved on the top rod 1, the mounting frame 9 is mounted on the first mounting member, the winding roller 10 is mounted on the mounting frame 9, the rocker 11 is mounted on one end of the winding roller 10 and is arranged on one side of the mounting frame 9, the limiting member is mounted on one side of the mounting frame 9, and the lower end extends into the rocker 11, which is used to limit the rocker 11 and the winding roller 10.

[0064] On the basis of the above structure, when it is necessary to release or reel in the cable, the user drives the reel 10 to rotate by shaking the rocker 11. The limiter ensures that the rocker 11 and the reel 10 rotate within a set range to prevent excessive rotation. The user can release or reel in the cable by simply shaking the rocker 11, which is easy and quick to operate. The design of the limiter effectively limits the rotation range of the rocker 11 and the reel 10, enhancing safety during use.

[0065] In a preferred embodiment of the present invention, the first mounting member includes a first mounting sleeve rod 7 and a first fixing screw block 8, the first mounting sleeve rod 7 is sleeved on the outside of the top rod 1, the first fixing screw block 8 is threadedly installed on the first mounting sleeve rod 7, and extends to the inside of the first mounting sleeve rod 7, and is attached to the top rod 1, and the mounting frame 9 is installed on the first mounting sleeve rod 7; a fixing block 12 is installed on one side of the mounting frame 9, and a limiting member is installed on the fixing block 12; the limiting member includes a threaded rod 13 and an insert block 14, the insert block 14 is installed at the lower end of the threaded rod 13, and the threaded rod 13 is threadedly installed on the fixing block 12; the rocker 11 includes a rocking part and a limiting part, the limiting part is arranged between one end of the rocking part and one end of the winding roller 10, and the circumferential outer annular array of the limiting part has a slot 15 adapted to the insert block 14.

[0066] During assembly, the first installation sleeve rod 7 is first sleeved on the top rod 1, and then the first fixing screw block 8 is rotated to press the connecting rod tightly, so that the winding structure is firmly installed on the connecting rod.

[0067] When it is necessary to release the cable, the user rotates the threaded rod 13 upwards to move the plug block 14 upwards and separate it from the slot 15. Then, the user can shake the rocker 11 to drive the winding roller 10 to rotate, thereby releasing the cable.

[0068] When it is necessary to stop paying out the wire, the user rotates the threaded rod 13 downwards, so that the plug block 14 moves downwards and engages with the upwardly facing slot 15 on the limiting portion. In this way, the rotation of the rocker 11 and the winding roller 10 is restricted, thereby ensuring that the wire will not be accidentally released.

[0069] In a preferred embodiment of the present invention, the auxiliary fixing structure includes a second mounting member and a mounting rod 18 in an annular array along its outer circumference. The auxiliary fixing structure also includes a support member and a support rod 21 arranged on the mounting rod 18 and a driving member arranged on the second mounting member. The second mounting member is installed on the bottom rod 3, and the mounting rod 18 is rotatably arranged between the second mounting member and the support member; a slider 22 is connected to the lower end of the driving member, and the support rod 21 is rotatably arranged between the mounting rod 18 and the slider 22. The driving member drives the slider 22 to move, so that the support rod 21 opens the mounting rod 18, which is used to assist in supporting the support column.

[0070] In a preferred embodiment of the present invention, the second mounting member includes a second mounting sleeve rod 16 and a second fixing screw block 17. The second mounting sleeve rod 16 is sleeved on the bottom rod 3, and the second fixing screw block 17 is threadedly installed on the second mounting sleeve rod 16. One end of the second fixing screw block 17 extends into the second mounting sleeve rod 16 and is in contact with the bottom rod 3; the slider 22 is sleeved on the bottom rod 3 and is arranged below the second mounting sleeve rod 16. The slider 22 is a hollow cylinder. The outside of the slider 22 and the outside of the second mounting sleeve rod 16 are respectively provided with protrusions 25 in a circumferential annular array that is compatible with the number of mounting rods 18. The upper and lower protrusions 25 are symmetrically arranged, and three mounting rods 18 are arranged.

[0071] When the device is assembled, the second mounting sleeve rod 16 is moved from bottom to top and sleeved on the connection at the bottom, while driving the slider 22 to move up and sleeved on the connecting rod. The second fixing screw block 17 is screwed inward so that one end of it squeezes the connecting rod until it cannot move further. At this time, the second mounting sleeve rod 16 cannot move up and down, thereby realizing the limited installation of the second mounting sleeve rod 16 and the structure installed outside it. When the support column needs to be auxiliary supported, the driving member drives the slider 22 to move. The movement of the slider 22 drives the support rod 21 and the mounting rod 18 to move, so that the support rod 21 opens the mounting rod 18. The opening of the mounting rod 18 causes the support member to move accordingly and provide a stable supporting force to the support column, thereby preventing the bottom rod 3 from tilting and affecting the line-laying effect. In this way, the various components of the auxiliary fixing structure are assembled together through a stable connection method, ensuring the stability and durability of the overall structure. Driven by the driving member, the slider 22, the support rod 21 and the mounting rod 18 can move flexibly to achieve auxiliary support for the support column. The auxiliary fixing structure can adjust the support strength and position of the support column according to actual needs, and has strong adaptability. The assembly process is simple and quick, and the installation can be completed by simply sleeve the second installation sleeve rod 16 and the slider 22 on the connecting rod and screwing the second fixing screw block 17.

[0072] In a preferred embodiment of the present invention, the support member includes a mounting plate 19 and an insertion rod 20 in a rectangular array at its bottom, the mounting plate 19 is in contact with the ground, and the insertion rod 20 and the bottom rod 3 are both inserted into the ground; the upper end of the mounting rod 18 is rotatably mounted on the second mounting sleeve rod 16, the lower end of the mounting rod 18 is rotatably mounted on the mounting plate 19, one end of the support rod 21 is rotatably mounted on the side of the mounting rod 18 close to the second mounting sleeve rod 16, and the other end of the support rod 21 is rotatably mounted on the slider 22.

[0073] When auxiliary support is required for the support column, the driving member drives the slider 22 to move. The movement of the slider 22 drives the support rod 21 to move. Since one end of the support rod 21 is rotatably mounted on the mounting rod 18 and the other end is rotatably mounted on the slider 22, the support rod 21 pushes the mounting rod 18 to rotate around its rotation point on the second mounting sleeve rod 16 and the mounting plate 19. The rotation of the mounting rod 18 causes the support member (i.e., the mounting plate 19 and the insertion rod 20) to move accordingly and provide a stable supporting force for the support column. The firm connection between the insertion rod 20 and the ground ensures that the support member will not slide or move, thereby improving the stability of the overall structure.

[0074] In a preferred embodiment of the present invention, the driving member includes a toothed plate 24, a gear 26 and a rotating block 27. The toothed plate 24 is mounted on one of the protrusions 25 on the slider 22, and the toothed plate 24 passes through one of the protrusions 25 on the second mounting sleeve rod 16. The gear 26 is meshingly arranged on the outside of the toothed plate 24, and the rotating block 27 is installed on one side of the gear 26; an installation box 28 is installed outside the second mounting sleeve rod 16, the gear 26 is installed in the installation box 28, the toothed plate 24 passes through the installation box 28, the rotating block 27 is arranged outside the installation box 28, and one end thereof extends into the inside of the installation box 28; guide rods 23 are respectively mounted on the other two protrusions 25 on the slider 22, and the guide rod 23 passes through the protrusion 25 on the upper second mounting sleeve rod 16, and the guide rod 23, the protrusion 25 and the toothed plate 24 are all staggered with the mounting rod 18.

[0075] When the slider 22 needs to be driven to move, the operator or mechanical device will rotate the rotating block 27, and the rotation of the rotating block 27 will drive the gear 26 to rotate in the installation box 28. Since the gear 26 is meshed with the tooth plate 24, the rotation of the gear 26 will further drive the tooth plate 24 to move. The movement of the tooth plate 24 will be transmitted to the slider 22, so that it moves along the connecting rod. The movement of the slider 22 will further drive the support rod 21 and the installation rod 18 to move, thereby realizing auxiliary support for the support column. The guide rod 23 ensures the stability and directionality of the slider 22 during the movement. In this way, the present invention ensures the stability and directionality of the slider 22 during the movement through the design of the driving member and the addition of the guide rod 23. The meshing design of the gear 26 and the tooth plate 24 and the protective function of the installation box 28 improve the reliability of the system. By rotating the rotating block 27 manually or mechanically, the movement of the slider 22 and the auxiliary support of the support column can be conveniently controlled. The driving member can be adjusted according to actual needs to adapt to different working environments and support requirements. At the same time, the staggered design avoids interference between components and improves the compactness and practicality of the overall structure.
