[0042] In order to enable those skilled in the art of the present technology to better understand the solutions of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0045] Figure 1 Schematic diagram of a gripping device provided by an embodiment of the utility model. Figure 1 As shown, it includes a grabbing component 101, an image acquisition component 102 and a folding component 103; wherein the grabbing component 101 is connected to one end of the folding component 103 for grabbing; the image acquisition component 102 is arranged on one side of the grabbing component 101 for acquiring a grabbing state image of the grabbing component 101; the folding component 103 includes at least two folding rods 1031, and a hoisting receiving unit 1032 is arranged on one side of the folding rod 1031 away from the grabbing component 101 for being hoisted and lifted by an external hoisting device.

[0046] Specifically, Figure 1 As shown, the image acquisition component 102 is disposed on one side of the grabbing component 101, wherein the image acquired by the image acquisition component 102 is the captured image of the grabbing component 101. Optionally, the operator can receive the image information acquired by the image acquisition component 102 through a display device to monitor the grabbing situation of the grabbing component 101 in real time and make adjustments at any time.

[0047] Continue to refer to Figure 1 The folding assembly 103 is provided with two folding rods, a first folding rod 10311 and a second folding rod 10312, wherein the first folding rod 10311 is provided with a first hoisting receiving unit 10321; the second folding rod 10312 is provided with a second hoisting receiving unit 10322. The corresponding hoisting receiving unit can be selected according to the distance between the grabbing target and the external hoisting device, such as Figure 1When the grab target is far from the external lifting device, a longer folding rod is needed for grabbing, so the first lifting receiving unit 10321 can be selected to be connected with the external lifting device so that the gripping device is lifted by the external lifting device. When the grab target is close to the external lifting device, a shorter folding rod is needed for grabbing, so the second lifting receiving unit 10322 can be selected to be connected with the external lifting device so that the gripping device is lifted by the external lifting device.

[0048] When the gripper device needs to grab the filter element, the gripper device can also be configured according to the current working environment: when the operating environment on the ground in the working environment is small and the filter element in the filter element storage well is close to the ground, the pull rod in the gripper device can be folded according to the operating environment on the ground. Figure 1 As shown, according to the limitation of the working space on the ground, the first pull rod 10331 can be folded around the first folding portion 10341 during the grabbing stage, and the external lifting device is connected to the second lifting receiving unit 10322. If the depth of the filter element in the filter element storage well is shallow and the required folding assembly is short, then such a gripper device can be used to grab the filter element.

[0049] When lifting the gripper, the folding rod needs to be folded due to the limitation of the lifting range of the lifting device. Then, the external lifting device can be unloaded from the first lifting receiving unit 10321 and connected to the second lifting receiving unit 10322. After the external lifting device is unloaded from the first lifting receiving unit 10321, the first pull rod 10331 rotates along the first direction around the first folding portion 10341. After the external lifting device is connected to the second lifting receiving unit 10322, the gripper device 100 continues to lift.

[0050] In the prior art, the pull rod of the gripper device cannot be folded. In actual application, if the working environment at that time is small, the staff needs to replace the pull rod. In the gripper system provided by the embodiment of the utility model, when the operating environment is small, the design of the folding pull rod allows the gripper device to be folded up when not in use or when entering a small space to reduce the overall volume, thereby making it easier to enter and adapt to a small operating environment. This design helps the gripper device in the gripper system to operate flexibly in a limited space, thereby improving work efficiency. At the same time, the design of the folding pull rod allows the gripper device to fold and stow unnecessary pull rods when the required pull rod length is not high, thereby avoiding occupying space when not in use and reducing the risk of collision and damage. In addition, by adjusting the folding angle and number of the pull rods, the gripper device can adapt to the requirements of grabbing filter elements of different heights and positions, thereby improving its flexibility and versatility.

[0051] The embodiment of the utility model discloses a gripping device, including a gripping component, an image acquisition component and a folding component; wherein the gripping component is connected to one end of the folding component for gripping; the image acquisition component is arranged on one side of the gripping component for capturing the gripping state image of the gripping component; the folding component includes at least two folding rods, and a hoisting receiving unit is arranged on the side of the folding rod away from the gripping component for being hoisted and lifted by an external hoisting device. The gripping device provided by the utility model can grip the filter element in the waste filter element storage well, and each folding rod is provided with a hoisting receiving unit to adapt to waste filter element storage wells of different depths, thereby reducing the operating space required by the gripping device; at the same time, the image acquisition component can also grasp the gripping state of the component in real time, so as to facilitate the operator to center and grip the filter element handle, improve work efficiency, and reduce occupational exposure time.

[0052] Figure 2 This is a schematic diagram of another gripper device structure provided by an embodiment of the utility model. Figure 2 As shown, the folding assembly 103 also includes at least three pull rods 1033, and a folding portion 1034 is provided between two adjacent pull rods 1033; the pull rod 1033 can rotate within a preset angle range around the folding portion 1034 on the side of the pull rod 1033 close to the grasping assembly; wherein, the rotation directions of two adjacent pull rods 1033 are opposite.

[0053] Specifically, Figure 2 As shown, the folding assembly 103 includes a first pull rod 10331, a second pull rod 10332, and a third pull rod 10333. A first folding portion 10341 is provided between adjacent first pull rods 10331 and second pull rods 10332; a second folding portion 10342 is provided between adjacent second pull rods 10332 and third pull rods 10333. The first pull rod 10331 can rotate in a first direction within a preset angle range around the first folding portion 10341, and the second pull rod 10332 can rotate in a second direction within a preset angle range around the second folding portion 10342. The first direction is opposite to the second direction.

[0054] When at least three pull rods are provided, and the adjacent folding pull rods rotate in opposite directions around the folding portion, as Figure 2 As shown, when the adjacent folding rods rotate in opposite directions, all the rods are folded in a manner close to a "Z" shape, and they can fit together more closely in the folded state, further reducing the required space. At the same time, by alternating the rotation direction, the folding rods can form a smoother mechanical action during the folding and unfolding process, reducing the movement resistance, making the operation of the entire mechanism more convenient and quick. In addition, folding the folding assembly in this way also prevents the rods in the folding assembly from being squeezed due to folding, causing damage to the rods.

[0055] Optionally, the preset angle range can be 180 degrees. When the rotation angle is 180 degrees, the wiring of the power line and cable inside the folding part is relatively easy, and the power line and cable will not be damaged due to the folding of the folding part.

[0056] Figure 3 Schematic diagram of a grasping component structure provided by an embodiment of the present invention Figure 4 is Figure 3 a plan view along the X direction Figure 5 is Figure 3 a plan view along the Y direction. As Figures 3 - 5 shown, the grasping component includes a first connection unit 1011, at least two grasping units 1012, and a driving unit 1013; wherein, the first connection unit 1011 is arranged on one side of the driving unit 1013 close to the folding component 103 for connecting the grasping component to one end of the folding component 103; at least two grasping units 1012 are oppositely arranged on both sides of the driving unit 1013 for grasping; the grasping unit 1012 includes two claws, and the clamping planes of at least two grasping units 1012 are parallel.

[0057] Optionally, as Figure 3 shown, the first connection unit 1011 can be a mounting plate, and the mounting plate includes a first hole 10111 arranged in the center and a second hole 10112 arranged around the first hole. The first hole 10111 is communicated with the driving unit 1013 for routing and arranging the power line or cable; the second hole 10112 is arranged around the mounting plate for connecting to the folding component 103 through screws, so that the grasping component is connected to the folding component 103. Specifically, the structure of the first connection unit is set according to the actual situation and is not limited herein.

[0058] Optionally, the outer surface of the driving unit 1013 is a metal shell, and a driving mechanism is arranged inside the metal shell for driving the grasping unit. Specifically, the structure of the driving mechanism is set according to the situation of the grasping unit 1012 in practice and is not limited herein.

[0059] Specifically, as Figures 3 - 5 shown, the first grasping unit 10121 and the second grasping unit 10122 are arranged on both sides of the driving unit 1013 for grasping operations; and the grasping unit 1012 includes two claws, and the two claws form a clamping plane, and the clamping planes of the first grasping unit 10121 and the second grasping unit 10122 are parallel. The handle of the filter element of the nuclear power plant waste (water) filter includes a "one"-shaped handle, and setting claws with two parallel clamping planes can grasp the "one"-shaped handle of the filter element more firmly. Optionally, multiple grasping units can be set to grasp the filter element more firmly and stably.

[0060] Continue to refer to Figure 2 The folding assembly 103 further includes a second connection unit; the second connection unit is disposed on the third pull rod 10333 adjacent to the grasping assembly in the folding assembly, and is disposed on the side of the third pull rod 10333 close to the grasping assembly 101; the first connection unit and the second connection unit can be connected and disassembled.

[0061] Optionally, it may include grasping assemblies with multiple different grasping structures, and different grasping structures are used to adapt to the grasping of filters in different forms. And these grasping assemblies all include the same first connection unit. In actual situations, different grasping assemblies can be connected to the folding assembly through the first connection unit and the second connection unit for grasping. So that it is allowed to quickly adjust or change the configuration of the folding assembly as needed; in addition, the modular design enables faulty components to be replaced individually without replacing the entire device, which helps to reduce the maintenance cost.

[0062] Figure 6 Another schematic structural diagram of the grasping assembly provided by the embodiment of the present invention. Combining the above, as Figure 6 shown, the image acquisition assembly 102 is disposed on one side of the grasping assembly 101; the image acquisition assembly 102 includes an illumination unit and an image acquisition unit; wherein the direction of the image acquisition unit for acquiring images points to the gripper, and the image information of the clamping and releasing processes of all grippers is acquired; the illumination direction of the illumination unit points to the gripper.

[0063] In the gripper device provided by the embodiment of the present invention, an image acquisition assembly is provided to collect the grasping state of the grippers in the grasping assembly in real time and provide illumination for the grasping of the grippers. Through the real-time image information, the relative position, posture and the magnitude of the clamping force between the gripper and the target object can be accurately judged. The design of the illumination unit ensures sufficient illumination in the gripper area, enabling the image acquisition unit to obtain clear and high-quality image information. It is beneficial to improve the accuracy and efficiency of image processing. The gripper device provided by the embodiment of the present invention realizes real-time monitoring during the grasping process.

[0064] Figure 7 Another schematic structural diagram of the gripper device provided by the embodiment of the present invention, wherein Figure 7 The upper part is a schematic structural diagram of the locking sleeve in the locked state, Figure 7 The lower part is a schematic structural diagram of the locking sleeve in the released state. Combining the above, as Figure 7 shown, each folding part 1034 is correspondingly provided with a locking sleeve 201, and the locking sleeve 201 is sleeved on the folding assembly 103; the locking sleeve 201 can move along at least one of the two pull rods connected to the folding part 1034 to lock the folding part 1034 and the two pull rods connected to the folding part 1034, or release the folding part 1034 and the two pull rods connected to the folding part 1034.

[0065] Specifically, as Figure 7 shown in the upper part, when the locking sleeve 201 is in the locked state, the folding connecting piece 202 is sleeved by the locking sleeve 201, and at this time, the folding assembly 103 cannot be folded; as Figure 7 shown in the lower part, when the locking sleeve 201 is in the released state, the locking sleeve 201 moves along the first pull rod 10331 connected to the folding part 1034. At this time, the folding connecting piece 202 is disengaged from the sleeved state of the locking sleeve 201. At this time, the locking sleeve 201 releases the folding part 1034 and the first pull rod 10331 and the second pull rod 10332 connected to the folding part 1034. Optionally, the locking sleeve 201 can move along the first pull rod 10331 or along the second pull rod 10332. The specific moving direction of the locking sleeve is set according to the actual situation and is not limited here.

[0066] The embodiment of the present utility model provides a gripper device with a locking sleeve arranged on the folding part. When the gripper device grabs the filter element, at this time, the grabbing assembly is ready to grab the filter element, and since the pull rod is a foldable design, it will cause instability of the folding assembly. Based on this, the locking sleeve is designed. When two adjacent pull rods are at an angle of 180°, the locking sleeve can lock the folding connecting piece so that the two adjacent pull rods are in a stable state. To ensure the stable connection between the pull rods, reduce the shaking or misoperation during the grabbing process, prevent the accidental folding of the pull rods, and increase the safety, accuracy and reliability of the grabbing operation.

[0067] As Figure 1 shown, in combination with the above, the grabbing assembly 101 further includes an isolation unit 1014. Among them, the isolation unit 1014 is arranged on one side of the grabbing assembly 101 close to the folding assembly 103 and is used for isolating between the grabbing assembly 101 and the folding assembly 103. After the grabbing assembly grabs the filter element, as the lifting distance of the filter element from the operator gets closer and closer, its radiation dose will also increase accordingly. The isolation unit is arranged to isolate between the grabbing assembly and the folding assembly, which is beneficial to isolating radiation and protecting the safety and health of the operator.

[0068] The embodiment of the present utility model also provides a gripper system. Figure 8 As a structural schematic diagram of a gripper system provided by the embodiment of the present utility model, as Figure 8 shown, it includes a gripper device 100 and an isolation device 200. The isolation device 200 includes a first locking component 2001; the first locking component 2001 is used for fixing the gripper device 100.

[0069] Specifically, Figure 9 As a structural schematic diagram of the gripper system provided by the embodiment of the present utility model when the gripper device performs grabbing; Figure 10A schematic diagram of the structure of the gripping device system provided by the embodiment of the utility model when the gripping device is lifting; Figure 11 This is a schematic diagram of the structure of the gripper system provided by the embodiment of the utility model when the gripper device completes gripping.

[0070] like Figure 9 As shown, the gripping device 100 is used for gripping, and the gripping device 100 is lowered to the depth of the storage well for gripping. At this time, due to the large gripping depth, a longer folding rod is required for gripping, and the external lifting device is connected to the first lifting receiving unit 10321 for lifting the gripping device 100. Figure 10 As shown, the gripper device 100 is lifted, and as the distance between the gripper device and the ground gradually decreases, the folding rod of the gripper device exposed on the ground is not enough to accommodate the lifting range of the lifting device and / or the height between the ground and the ceiling, so the folding rod needs to be folded. At this time, the first locking assembly 2001 fixes the gripper device 100 so that the gripper device is suspended, and the external lifting device is unloaded from the first lifting receiving unit 10321 and connected to the second lifting receiving unit 10322. After the external lifting device is unloaded from the first lifting receiving unit 10321, the first pull rod 10331 rotates around the first folding portion 10341 in the first direction. After the external lifting device is connected to the second lifting receiving unit 10322, the first locking assembly 2001 ends the fixation of the gripper device 100, and the gripper device 100 continues to be lifted.

[0071] Optional, such as Figure 10 As shown, according to the limitation of the working space on the ground, the first pull rod 10331 can be folded around the first folding portion 10341 during the grabbing stage, and the external lifting device is connected to the second lifting receiving unit 10322. If the depth of the filter element in the filter element storage well is shallow and the required folding assembly is short, then such a gripping device can be used to grab the filter element. This design helps the gripping device in the gripping system to operate flexibly in a limited space, thereby improving work efficiency.

[0072] like Figure 11 As shown, when the gripping device 100 is finished, the gripping device 100 is lifted, and the first locking assembly 2001 fixes the gripping device 100, and the external lifting device is unloaded from the connection of the gripping device. At this time, the second pull rod 10332 rotates around the second folding portion 10342 along the second direction.

[0073] The embodiment of the utility model provides a gripping system, including an isolation device and the above-mentioned gripping device; the isolation device includes a first locking assembly; the first locking assembly is used to fix the gripping device. When the gripping device is from gripping to gripping completion, the first locking assembly locks the gripping device to cooperate with the external lifting device to unload and reconnect the lifting receiving unit. In this way, the gripping system can adapt to waste filter element storage wells of different depths, reduce the operating space required for the gripping device, and improve the scope of application and reliability of the gripping system.
