[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a salvage claw for sewage treatment. The structure of the traditional salvage claw is relatively simple, and objects are usually grabbed by claw pieces only. The salvage claw is generally not provided with additional fixing parts, especially for objects with relatively smooth surfaces, which easily leads to the problem of falling off during the grabbing process. In the utility model, the outer cavity shell material connecting the main block, the claw piece block and the adsorption cavity block components is made of iron-carbon alloy as raw material. After precise processing and heat treatment process, the iron-carbon alloy has strong impact resistance and bending resistance, ensuring its structural strength and durability. It has been precisely welded and strengthened, can withstand strong impact and pressure, is not prone to deformation, breakage, etc., and effectively improves the service life of the salvage claw. In order to solve the above problems, when the user of the utility model uses the salvage claw to clamp floating objects on the water, the object to be clamped is placed between the two groups of claw fixing components, and the two groups of hydraulic cylinders are started at the same time to extend the hydraulic cylinders. The hydraulic cylinders will push the opening side of the claw block to tilt toward the side close to the object. At this time, the bevel angle of the hydraulic cylinder changes, and it will rotate clockwise between the two groups of fixed plates. The two groups of claw blocks are close to the side close to the object until the two groups of claw blocks are clamped against the two sides of the object by the drive of the hydraulic cylinder, and the adsorption cavity block components are tightly attached to the sides of the object. The user turns on the two groups of automatic telescopic rods to shrink the automatic telescopic rods, and the automatic telescopic rods drive the piston to move along the inner cavity of the air cylinder to the side away from the suction cup. The air is sucked away, forming a negative pressure state, so that the suction cup is closely fitted to the object to be clamped, and the two groups of suction cups are used to adsorb and fix the side of the object, further strengthening the clamping firmness of the claw fixing assembly; when the clamped object needs to be released, the automatic telescopic rod is started and extended, and the automatic telescopic rod drives the piston to move along the inner cavity of the air cylinder toward the side close to the suction cup. At this time, the two groups of suction cups lose the adsorption and fixing effect on the object, and subsequently the two groups of hydraulic cylinders are started to contract the hydraulic cylinders, and the hydraulic cylinders drive the opening of the claw block to move toward the side away from the object. The two groups of claw blocks move away from each other, giving up clamping and fixing the object, and the object can be placed in the designated location. This setting, through the design of the claw fixing assembly, allows the salvage claw to not only use the claw piece for clamping, but also use the adsorption effect of the suction cup to further increase the fixing effect on the object, and the operation is simple and quick, thereby improving the practicability and work efficiency of the device.

[0016] 2. The utility model discloses a salvage claw for sewage treatment. After the salvage claw is used for a long time, it needs to be replaced and maintained. However, the existing salvage claw and salvage support assembly are mostly integrated devices. The salvage claw is not easy to be disassembled from the salvage support assembly, which makes it difficult for users to replace or maintain the salvage claw. To solve the above problem, if the user needs to disassemble and replace the claw head of the salvage claw, the utility model rotates the knob in the opposite direction, and the knob drives the threaded rod and the gear to rotate. The gear will drive the upper and lower rack blocks to slide, and the two sets of rack blocks will move away from each other, and the rack blocks will slide horizontally along the long cavity groove block on one side, and the two sets of rack blocks will drive the first connecting plate and the second connecting plate to move away from each other until the multiple sets of plug-in fixing columns completely leave the first cavity grooves at the corresponding positions, and the first cavity grooves are separated from the plug-in fixing columns, and the plug-in fixing plates lose the clamping effect of the multiple sets of plug-in fixing columns. After that, the user pulls the supporting main block to the side away from the installation cavity box, so that the plug-in plate is pulled out of the inner cavity of the installation cavity box, and the claw piece fixing assembly can be disassembled; if it is necessary to reinstall the fixed claw piece fixing assembly, the plug-in plate is reinserted into the inner cavity of the installation cavity box, and the plug-in plate is located between the second connecting plate and the first connecting plate, and the knob is turned forward. The knob drives the gear to rotate, and the two sets of rack blocks move closer to each other, and the first connecting plate and the second connecting plate move closer to each other until the multiple sets of plug-in fixing columns are inserted into the corresponding first cavity groove cavities, the first cavity groove and the plug-in fixing columns are clamped and fixed, and the plug-in plate is clamped and fixed between the first connecting plate and the second connecting plate, that is, the salvage claw is fixed and installed. This arrangement makes it easy to disassemble the salvage claw, and it is convenient for users to perform maintenance work on the salvage claw, prevent the claw piece fixing assembly from being damaged due to long-term use and affect the normal use effect, and improve the practicality of the device.

[0032] In summary: the utility model discloses a salvage claw for sewage treatment. The traditional salvage claw has a relatively simple structure and usually relies solely on the claw piece to grab objects. The salvage claw is generally not provided with additional fixing parts, especially for objects with relatively smooth surfaces, which can easily cause the claw to fall off during the grabbing process. In the utility model, the outer cavity shell material connecting the main block 31, the claw piece block 32 and the adsorption cavity block component 33 is made of iron-carbon alloy as raw material. After precise processing and heat treatment process, the iron-carbon alloy has strong impact resistance and bending resistance, ensuring its structural strength and durability. The utility model discloses that when using the salvage claw to clamp floating objects on the water, the user places the objects to be clamped between the two groups of claw fixing components 3, and starts the two groups of hydraulic cylinders 35 to extend the hydraulic cylinders 35, and the hydraulic cylinders 35 will push the opening side of the claw block 32 to tilt toward the side close to the object. At this time, the bevel angle of the hydraulic cylinder 35 changes, and the hydraulic cylinder 35 will rotate clockwise between the two groups of fixing plates 34. The two groups of claw blocks 32 are close to the side close to the object until the two groups of claw blocks 32 are clamped against the two sides of the object by the drive of the hydraulic cylinder 35, and the suction chamber block component 33 is tightly attached to the side of the object. The user turns on the two groups of automatic telescopic rods 332 to make the automatic telescopic rods 332 contract, and the automatic telescopic rods 332 will drive the piston 335 to move along the inner cavity of the air cylinder 333 to the side away from the suction cup 331. When the object is to be released, the automatic telescopic rod 332 is started and the automatic telescopic rod 332 is extended, and the automatic telescopic rod 332 drives the piston 335 to move along the inner cavity of the air cylinder 333 toward the side close to the suction cup 331. At this time, the two groups of suction cups 331 lose the adsorption and fixing effect on the object, and subsequently the two groups of hydraulic cylinders 35 are started to make the hydraulic cylinders 35 contract, and the hydraulic cylinders 35 drive the opening of the claw piece block 32 to move away from the object. The two groups of claw piece blocks 32 move away from each other, giving up the clamping and fixing of the object, and the object can be placed at the designated location. This setting, through the design of the claw piece fixing assembly 3, enables the salvage claw to not only use the claw piece for clamping, but also use the adsorption effect of the suction cup to further increase the fixing effect on the object, and the operation is simple and quick, thereby improving the practicability and work efficiency of the device.

[0033] After the salvage claw is used for a long time, it needs to be replaced and maintained. However, the existing salvage claw and salvage support assembly are mostly integrated devices. The salvage claw is not easy to be disassembled from the salvage support assembly, which makes it difficult for users to replace or maintain the salvage claw. To solve the above problem, if the user needs to disassemble and replace the claw head of the salvage claw, the knob 22 is rotated in the opposite direction. The knob 22 drives the threaded rod 23 and the gear 24 to rotate. The gear 24 will drive the upper and lower rack blocks 26 to slide. The two sets of rack blocks 26 move away from each other, and the rack blocks 26 will slide horizontally along the long cavity groove block 25 on one side. The two sets of rack blocks 26 will drive the first connecting plate 28 and the second connecting plate 29 to move away from each other until the multiple sets of plug-in fixing columns 291 completely leave the first cavity groove 121 at the corresponding position, and the first cavity groove 121 is separated from the plug-in fixing column 291. After the plug-in plate 12 loses the locking effect of the multiple sets of plug-in fixing columns 291, the user moves away from the installation cavity box 21. The first and second connecting plates 29 are then engaged and fixed to the respective first and second connecting plates 29. When the first and second connecting plates 29 are engaged, the first and second connecting plates 29 are engaged and fixed to the respective first and second connecting plates 29. The fixing plate 12 is then engaged and fixed to the respective first and second connecting plates 29. When the first and second connecting plates 29 are engaged, the fixing plate 12 is then engaged and fixed to the respective first and second connecting plates 29.
