Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clamping technology, and specifically relates to a clamping mechanism. Background Technology
[0002] The hydrological cableway signal tube is a device used in hydrological monitoring equipment to collect and transmit water flow velocity data. It is mainly used for flow monitoring in water bodies such as rivers, lakes and reservoirs. The working principle is to convert the water flow velocity into an electrical signal through a contact wire or sensor, and then transmit it to the onshore equipment for data reception and processing through the underwater signal tube.
[0003] As a crucial component of cableway flow measurement, the performance and quality of the hydrological cableway signal cylinder directly affect the accuracy and results of the test. In actual maintenance, it is necessary to regularly check the electrode status of the signal cylinder and calibrate the parameters to adapt to changes in fluid. Currently, signal cylinders on the market typically consist of a cylindrical stainless steel casing housing a lithium battery, main control circuit board, radio frequency module, and connector, protected by a sealing ring and a cap for waterproofing. The cap is usually quite narrow, and during actual testing and maintenance, it is easy for poor sealing to occur due to inadequate tightening, resulting in water ingress under underwater pressure, damaging the lithium battery and circuit board, and affecting the test quality.
[0004] To address this issue, the hydrological cableway signal cylinder requires a clamping mechanism for stable clamping during assembly and disassembly. The end cap is then removed to remove the internal electronic components before being tightened. Therefore, a clamping mechanism is an essential auxiliary tool in the assembly and disassembly of the hydrological cableway signal cylinder. Various existing mechanisms exist for clamping and fixing hydrological cableway signal cylinders. For example, Chinese utility model patent CN212044281U discloses a bench vise, comprising: a base, a fixed jaw, and a movable jaw. A fixed jaw is fixedly mounted on one end of the base, and a movable jaw is slidably mounted on the other end. A driving mechanism is provided within the base, which drives the movable jaw to move closer to the fixed jaw, allowing the fixed jaw and movable jaw to cooperate for clamping. However, when using the aforementioned bench vise to clamp the hydrological cableway signal cylinder, the following problems arise.
[0005] In the aforementioned bench vise, the moving jaws and fixed jaws are straight-plate structures, while the hydrological cableway signal cylinder is cylindrical. When the moving jaws and fixed jaws work together to clamp the hydrological cableway signal cylinder, the contact area between the straight-plate moving jaws and fixed jaws and the hydrological cableway signal cylinder is small, resulting in only single-line contact. Under these circumstances, the hydrological cableway signal cylinder is prone to movement during the disassembly and assembly of the end cap. Therefore, the aforementioned bench vise cannot guarantee the stability of the hydrological cableway signal cylinder during disassembly and assembly, nor can it guarantee the sealing effect of the end cap, causing certain inconvenience to the use of the hydrological cableway signal cylinder.
[0006] Therefore, in order to solve the above problems, this utility model provides a clamping mechanism for clamping and fixing the hydrological cableway signal cylinder, ensuring that the end cap of the hydrological cableway signal cylinder is in a stable state during the disassembly and assembly process, thereby facilitating the removal and installation of the end cap from the hydrological cableway signal cylinder, and ensuring the sealing effect of the end cap on the hydrological cableway signal cylinder.

[0014] As a preferred technical solution of this utility model, the side of the clamping member facing the clamping area is provided with anti-slip texture, which enhances the friction when the clamping member comes into contact with the object to be clamped.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In this invention, the size of the clamping area is adjusted by moving the movable seat relative to the fixed plate, and the hydrological cableway signal cylinder is clamped and fixed by the clamping component. This ensures the stability of the hydrological cableway signal cylinder during the installation and removal of the end cap.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0040] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0041] Example 1:
[0042] like Figure 1 , Figure 2 and Figure 3As shown, this is a schematic diagram of the clamping mechanism in this embodiment. The clamping mechanism in this embodiment is used to clamp the hydrological cableway signal cylinder to facilitate its assembly and disassembly, thereby assembling components into the hydrological cableway signal cylinder and ensuring its stability by clamping the hydrological cableway signal cylinder. The end cap is also tightened onto the end of the hydrological cableway signal cylinder to seal it. The clamping mechanism in this embodiment includes an installation component 1 and a clamping component 2. The clamping component 2 is fixed on the top of the installation component 1 and clamps and fixes the hydrological cableway signal cylinder. The installation component 1 fixes the clamping mechanism in this embodiment on the workbench so that the clamping component 2 can clamp the hydrological cableway signal cylinder, making it convenient for operators to inspect and maintain the hydrological cableway signal cylinder.
[0043] When inspecting underwater signal tubes for hydrological cableways, the signal tube is placed on clamping assembly 2. The operation of clamping assembly 2 squeezes the two sides of the signal tube to achieve stable clamping of the signal tube, making it easier for subsequent operators to tighten the tube cover.
[0044] like Figure 4 As shown, this is a structural schematic diagram of the clamping component 2 in this embodiment. Figure 3 as well as Figure 4 As shown, the clamping assembly 2 includes a fixed base 21, a fixed plate 22, and a movable base 23. The mounting assembly 1 is installed at the bottom of the fixed base 21. The fixed plate 22 is fixedly installed on the top of the fixed base 21, and the movable base 23 is also slidably mounted on the fixed base 21. In this embodiment, clamping members 24 are installed on the fixed plate 22 and the movable base 23. A clamping area is formed between the fixed plate 22 and the movable base 23. The movable base 23 moves relative to the fixed plate 22, causing the clamping members 24 to move towards the clamping area, thereby facilitating the clamping and fixing of the hydrological cableway signal cylinder in the clamping area.
[0045] like Figure 4 As shown, in this embodiment, a lead screw 25 is rotatably mounted on the fixed base 21. The lead screw 25 is threadedly connected to the movable base 23. A rotating handle 26 is installed at the end of the lead screw 25. By rotating the handle 26, the lead screw 25 can be driven to rotate, thereby enabling the movable base 23 to move along the linear direction of the lead screw 25. This is used to adjust the distance between the movable base 23 and the fixed plate 22, thus facilitating the clamping members 24 to cooperate in clamping and fixing the hydrological cableway signal cylinder. It is worth noting that the lead screw 25 in this embodiment is a driving mechanism for moving the movable base 23. Of course, other mechanisms capable of driving the movable base 23 to move can also be used in this embodiment.
[0046] As attached Figure 5As shown, this is a schematic diagram of the installation component 1 in this embodiment. The installation component 1 includes a side bracket 11, a mating seat 12, and a threaded rod 13. The side bracket 11 is fixedly installed at the bottom of the fixed seat 21. The mating seat 12 is installed at the end of the side bracket 11 away from the fixed seat 21. The threaded rod 13 is installed in the internal thread of the mating seat 12. The threaded rod 13 passes through the mating seat 12. A lifting plate 14 is installed at one end of the threaded rod 13, and a rotating end 15 is installed at the other end of the threaded rod 13. The rotating end 15 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the lifting plate 14 to move. The lifting plate 14 presses against the lower surface of the workbench, thereby fixing the clamping mechanism in this embodiment on the workbench to facilitate the clamping operation of the hydrological cableway signal cylinder.
[0047] like Figure 6 as well as Figure 7 As shown, it is a structural schematic diagram of the clamping member 24 in this embodiment. The clamping member 24 in this embodiment is in the shape of a "7". Specifically, the clamping member 24 in this embodiment includes a vertical part 241 and an inclined part 242. The top of the vertical part 241 is integrally formed with the inclined part 242, and the inclined direction of the inclined part 242 is upward from the vertical part 241 toward the clamping area.
[0048] When the clamping member 24 clamps the hydrological cableway signal cylinder, the movable seat 23 moves towards the fixed plate 22, thereby driving the clamping member 24 to move. This allows the clamping member 24 on the fixed plate 22 and the movable seat 23 to cooperate in clamping the hydrological cableway signal cylinder. After the clamping member 24 abuts against the hydrological cableway signal cylinder, the vertical part 241 abuts against the side of the hydrological cableway signal cylinder in a line contact state, and the inclined part 242 also abuts against the side of the hydrological cableway signal cylinder in a line contact state. This increases the contact points with the hydrological cableway signal cylinder and ensures the clamping effect of the clamping member 24 on the hydrological cableway signal cylinder.
[0049] It is worth noting that, in this embodiment, after the inclined part 242 abuts against the hydrological cableway signal tube, the hydrological cableway signal tube is also prevented from deflecting.
[0050] In this embodiment, by increasing the contact point between the clamping member 24 and the side wall of the hydrological cableway signal tube, the clamping effect of the clamping member 24 on the hydrological cableway signal tube is ensured, thereby facilitating the disassembly and assembly of the end cover of the hydrological cableway signal tube. After the end cover is assembled on the hydrological cableway signal tube, it is also easy to tighten the end cover, ensuring the sealing effect of the end cover.
[0051] Example 2:
[0052] like Figure 8 as well as Figure 9As shown, this is a schematic diagram of the clamping member 24 in this embodiment. The difference between the clamping member 24 in this embodiment and that in embodiment 1 is that, in order to further ensure the clamping effect of the clamping member 24, the clamping member 24 in this embodiment includes an arc-shaped part 243. A connecting block is installed on the back of the arc-shaped part 243. The clamping member 24 is respectively assembled on the fixed plate 22 and the movable seat 23 through the connecting block. When the hydrological cableway signal tube is clamped, the movable seat 23 moves and drives the clamping member 24 to move towards the fixed plate 22. The clamping members 24 cooperate with each other to clamp and fix the hydrological cableway signal tube in the clamping area. At this time, the arc-shaped part 243 is attached to the side wall of the hydrological cableway signal tube. Therefore, the clamping member 24 and the hydrological cableway signal tube are in surface contact, which further increases the contact area of the hydrological cableway signal tube, thereby ensuring the clamping effect.
[0053] It is worth noting that the radius of the arc-shaped part 243 in this embodiment is consistent with the radius of the hydrological cableway signal tube. Therefore, when the arc-shaped part 243 is attached to the hydrological cableway signal tube, the arc-shaped part 243 can be attached to the hydrological cableway signal tube in a surface contact state, ensuring the clamping effect.
[0054] Example 3:
[0055] like Figure 10 and Figure 11 As shown, this is a schematic diagram of the structure of the clamping member 24 in this embodiment. The difference between the clamping member 24 in this embodiment and that in embodiment 1 is that, in order to further ensure the clamping effect of the clamping member 24, the clamping member 24 in this embodiment includes a connecting part 244 and an enlarged part 245. The connecting part 244 is a straight plate structure, and the two ends of the connecting part 244 are integrally formed with the enlarged part 245, which is an arc-shaped structure. When it is necessary to clamp the hydrological cableway signal cylinder, the moving seat 23 moves relative to the fixed plate 22, so that the clamping member 24 approaches and clamps and fixes the hydrological cableway signal cylinder. During clamping, the connecting part 244 and the side wall of the hydrological cableway signal cylinder are in line contact, and the enlarged part 245 and the side wall of the hydrological cableway signal cylinder are in surface contact, thereby ensuring the clamping effect of the hydrological cableway signal cylinder.
[0056] Of course, the connecting part 244 in this embodiment can also be an arc-shaped structure. The arc radius of the connecting part 244 and the enlarged part 245 are the same. During the clamping process, the connecting part 244 and the enlarged part 245 respectively contact the surface of the hydrological cableway signal tube, which can also ensure the clamping effect of the hydrological cableway signal tube.
[0057] It is worth noting that the radius of the enlarged portion 245 in this embodiment is consistent with the radius of the hydrological cableway signal tube. Therefore, when the enlarged portion 245 is attached to the hydrological cableway signal tube, the enlarged portion 245 can be attached to the hydrological cableway signal tube in a surface contact state, ensuring the clamping effect.
[0058] In addition, in the above embodiments 1, 2 and 3, the side wall of the clamping member 24 facing the clamping area is provided with anti-slip texture. When the hydrological cableway signal tube is clamped, the anti-slip texture is used to increase the friction between the clamping member 24 and the hydrological cableway signal tube, further ensuring the clamping effect of the clamping member 24 on the hydrological cableway signal tube.
[0059] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
