Of course, the three preventative measures play different roles in the implementation process.

[0003] Detection, delay, and reaction are interdependent and indispensable. On the one hand, detection must be accurate, delay time must be appropriate, and reaction time must be rapid. On the other hand, the total reaction time should be less than (or at most equal to) the total time of detection plus delay: Treaction ≤ Tdetection + Tdelay.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0037] Now, a device for detecting the impact resistance strength of a fence structure provided by the present invention will be described.

[0038] As Figures 1 to 3As shown in the figure, a kind of impact strength detection device for a surrounding net structure provided by the present invention includes a support frame 1, a detection component 2, a control component, and a limit component 3. The support frame 1 is provided with a plurality of guide rails 11, and the guide rails 11 are vertically arranged on the support frame 1;

[0039] The detection component 2 includes a connecting plate 21, a vibrating cylinder 22, and a first driving member 23; the connecting plate 21 is horizontally arranged, and the connecting plate 21 is slidably connected to the guide rails 11; a vertically arranged vibrating cylinder 22 is provided on the lower end surface of the connecting plate 21, the vibrating cylinder 22 is fixedly arranged with the connecting plate 21, and the upper end of the vibrating cylinder 22 is connected to the connecting plate 21; the first driving member 23 is vertically arranged, and the power output end of the first driving member 23 is connected to the upper end surface of the connecting plate 21; the control component is electrically connected to the first driving member 23; the limit component 3 is arranged at the bottom of the support frame 1, and the limit component 3 is used for limiting and fixing the piece to be detected 10.

[0040] A kind of impact strength detection device for a surrounding net structure of the present invention includes a support frame 1, a detection component 2, a control component, and a limit component 3. The piece to be detected 10 is placed at the bottom of the support frame 1, and the limit component 3 limits and fixes the piece to be detected 10 to prevent the piece to be detected 10 from shifting during the strength detection of the piece to be detected 10, resulting in equipment damage. Start the control component, the control component drives the first driving member 23 to move, and then controls the connecting plate 21 to slide up and down on the guide rails 11, and finally drives the vibrating cylinder 22 to vibrate the piece to be detected 10, so as to detect the impact resistance performance of the piece to be detected 10, and solve the technical problem that the piece to be detected 10 is prone to shift during the detection of the impact resistance performance of the piece to be detected object in the prior art, resulting in easy damage to the equipment during the vibration process.

[0041] Further, please refer to Figure 3 , a receiving groove 12 is provided at the bottom of the support frame 1, the limit component 3 is arranged in the receiving groove 12, and the limit component 3 includes a supporting member 31, a clamping member 32, and a first spring 33. The supporting member 31 is slidably arranged along the vertical direction of the receiving groove 12, and a rack is vertically arranged on the side wall of the supporting member 31; the clamping member 32 is of an arc structure, a gear 321 is fixedly arranged at one end of the clamping member 32, the gear 321 is rotatably connected to the receiving groove 12, and the gear 321 meshes with the rack; the first spring 33 is vertically arranged at the bottom of the supporting member 31.

[0042] Among them, there are a plurality of clamping members 32, and the clamping members 32 are arranged at intervals along the circumference of the central axis of the supporting member 31.

[0043] When the workpiece 10 to be detected is placed on the top of the supporting member 31, the supporting member 31 is subjected to the pressure of the workpiece 10 to be detected, and the supporting member 31 slides downward along the vertical direction of the receiving groove 12. Since the side wall of the supporting member 31 is provided with a rack, and the gear 321 provided on the clamping member 32 meshes with the rack, when the supporting member 31 moves downward, it drives the clamping member 32 to flip, so as to clamp and fix the workpiece 10 to be detected. When it is necessary to take out the workpiece 10 to be detected, since the workpiece 10 to be detected is removed from the top of the supporting member 31, the acting force applied to the supporting member 31 by the workpiece 10 to be detected is cancelled, and the extrusion force received by the first spring 33 becomes smaller. Therefore, the first spring 33 returns from the compressed state to the natural state. Therefore, the supporting member 31 is reset under the elastic force of the first spring 33. When the supporting member 31 is reset, the rack drives the gear 321 to rotate, so as to drive the other end of the clamping member 32 away from the workpiece 10 to be detected.

[0044] Further, two jack holes 34 are provided on the side wall of the receiving groove 12, two symmetrically arranged connecting rods 35 are provided at the bottom of the supporting member 31, one end of each of the two connecting rods 35 is rotatably connected to the bottom of the supporting member 31, and the other end of each connecting rod 35 is inserted into the jack hole 34.

[0045] When the two connecting rods 35 are respectively inserted into the corresponding jack holes 34, the jack holes 34 are wedge-shaped holes. When the supporting member 31 moves downward, since one end of the connecting rod 35 is rotatably connected to the supporting member 31 and the other end is inserted into the jack hole 34, the smaller the angle between the connecting rod 35 and the horizontal plane becomes as the supporting member 31 moves downward until the central axes of the two connecting rods 35 are connected into a horizontal line. At this time, the connecting rod 35 plays a role of limiting and locking the supporting member 31.

[0046] Further, both ends of the reset member 36 are respectively connected to the rod bodies of the two connecting rods 35, and the reset member 36 is horizontally arranged. After the acting force applied to the supporting member 31 is cancelled, the reset member 36 drives the two connecting rods 35 to return to the initial state, drives the connecting rods 35 to be unlocked from the state of limiting and locking, and the first spring 33 drives the supporting member 31 to be reset.

[0047] Specifically, the reset member 36 is a reset spring.

[0048] On the basis of the above embodiments, please refer to Figure 4 and Figure 5 The detection assembly 2 further includes a second driving member 28, a first pushing member 24 and a drill rod 25. The first pushing member 24 is arranged on the upper end surface inside the vibrating cylinder 22, the second driving member 28 is connected to the power output end of the first pushing member 24, the drill rod 25 is vertically arranged in the vibrating cylinder 22, and one end of the drill rod 25 is connected to the power output end of the second driving member 28;

[0049] Among them, the second driving member 28 and the first pushing member 24 are respectively electrically connected to the control assembly. When the first pushing member 24 and the second driving member 28 are started, the second driving member 28 drives the drill rod 25 to rotate. Therefore, under the combined action of the first pushing member 24 and the second driving member 28, the drill rod 25 drills the workpiece to be detected 10, so as to detect the strength of the workpiece to be detected 10.

[0050] Since the fishing nets at different positions have different design requirements, the control assembly controls the feeding speed of the first pushing member 24 and the rotation speed of the second driving member 28, so as to perform strength detection in different ranges for fishing nets with different technical requirements.

[0051] Further, please refer to Figure 5 , a protective sleeve 27 is sleeved outside the drill rod 25. One end of the protective sleeve 27 is connected to the first pushing member 24, and a second spring 26 is provided between the protective sleeve 27 and the first pushing member 24. The protective sleeve 27 can prevent the drill rod 25 from damaging the inner wall of the vibrating cylinder 22 by the slag during the drilling process. The second spring 26 can not only play a role in shock absorption in real time, but also prevent the drill rod 25 from suddenly breaking during the drilling process, resulting in the second driving member 28 colliding with the workpiece to be detected 10 under the inertial action of the first pushing member 24 and damaging the second driving member 28.

[0052] The first driving member 23 and the first pushing member 24 are hydraulic cylinders, electric push rods or air cylinders.

[0053] The hydraulic cylinder mainly effectively converts hydraulic energy into mechanical energy. During use, it is mainly a hydraulic actuator that makes a linear reciprocating motion. The structure of the whole device is simple and reliable. When it is mainly used to achieve reciprocating motion during use, a speed reduction device can be omitted, and there is no transmission gap, and it is very stable during operation. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides. The hydraulic cylinder basically consists of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

[0054] The structural forms of hydraulic cylinders are diverse. According to their motion modes, they can be effectively divided into linear reciprocating motion type and rotary swing type. According to the situation of the hydraulic pressure acting on them, the equipment can be divided into single-acting type and double-acting type; according to the structural form, it can be divided into piston type, plunger type and swing type. In a single-acting hydraulic cylinder, pressure oil is only supplied to one chamber of the hydraulic cylinder, and the cylinder is made to move in one direction by the hydraulic pressure, while the reverse movement is achieved by external forces such as spring force, self-weight or external load, etc.; while for a double-acting hydraulic cylinder, the piston moves in two directions through the alternate oil inlet of the two chambers and is completed by the action of the hydraulic pressure. Piston-type hydraulic cylinders can be divided into two structural forms: single-rod type and double-rod type. Their fixing methods include cylinder body fixing and piston rod fixing, and according to the situation of the hydraulic pressure acting, there are single-acting type and double-acting type. In a single-acting hydraulic cylinder, pressure oil is only supplied to one chamber of the hydraulic cylinder, and the cylinder is made to move in one direction by the hydraulic pressure, while the reverse movement is achieved by external forces such as spring force, self-weight or external load, etc.; while for a double-acting hydraulic cylinder, the piston moves in two directions through the alternate oil inlet of the two chambers and is completed by the action of the hydraulic pressure. An electric push rod, also known as a linear actuator, is mainly a new type of linear actuator composed of a motor push rod and a control device and other mechanisms, and can be considered as an extension of a rotary motor in terms of structure. An electric push rod is a power-driven device that converts the rotary motion of an electric motor into the linear reciprocating motion of a push rod. It can be used as an execution machine in various simple or complex technological processes to achieve remote control, centralized control or automatic control. The electric push rod has the characteristics of novel and delicate design, small volume, high precision, complete synchronization, good self-locking performance, hygiene, direct drive by the motor, and no need for pipeline gas sources, oil circuits, etc. It has now been widely used in equipment in various industries such as production lines, automobiles, opening of ventilation windows, military, stages, textiles, sewage treatment, etc.

[0055] A rubber pad is provided on the inner arc side of the clamping member 32. The rubber pad increases the friction force between the clamping member 32 and the workpiece to be detected 10, further clamping the workpiece to be detected 10. At the same time, the rubber pad can also change the rigid connection between the clamping member 32 and the workpiece to be detected 10 into a flexible connection.

[0056] Further, the reset member 36 is a reset spring.

[0057] Further, scale lines are provided on the guide rail 11, and the setting of the scale lines facilitates the intuitive observation of the operator.

[0058] In summary, the present invention includes a support frame 1, a detection assembly 2, a control assembly and a limit assembly 3. Compared with traditional strength detection equipment, it not only has a relatively simple structure, but also because the first driving member 23, the second driving member 28 and the first pushing member 24 have different specifications, different models can be selected according to different working conditions, making the volume of the present invention more compact during the actual production process.

[0059] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
