DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-Figure 9 A concrete member prestress monitoring device shown includes a monitoring instrument body 1, an anchor plate 2 and an anchor 201, and a detection structure 3 is arranged between the anchor plate 2 and the anchor 201;

[0031] The detection structure 3 includes a mounting plate 301, a transmission module 302 is arranged on the top of the mounting plate 301, a sensor 303 is arranged on the side of the mounting plate 301 close to the anchor 201, a detection component 31 is arranged inside the mounting plate 301, and the transmission module 302 is signal-connected with the monitoring instrument body 1 and the sensor 303;

[0032] The detection assembly 31 includes a mounting seat 3101 disposed on one side of the mounting plate 301, a sensor 303 is disposed on the top of the mounting seat 3101, a knocking rod 3102 symmetrically distributed with the mounting seat 3101 and in contact with the surface of the anchor 201 is disposed on one side of the mounting plate 301, and the bottom of the mounting seat 3101 is in contact with the surface of the anchor 201;

[0033] One end of the striking rod 3102 close to the mounting plate 301 penetrates into the interior of the mounting plate 301 and is fixedly connected to a rotating shaft 3104 rotatably connected to the inner wall of the mounting plate 301, a spring 3105 is fixedly connected to the surface of the rotating shaft 3104, one end of the rotating shaft 3104 is fixedly connected to a rotating block 3106, and a connecting rod 3107 is fixedly connected to the surface of the rotating block 3106;

[0034] The mounting plate 301 has a sliding cavity inside, the inner wall of the sliding cavity is slidably connected to a connecting plate 3111, the top of the connecting plate 3111 is fixedly connected to an adsorption block 3112, the adsorption block 3112 is an iron metal material component, and the inner top wall of the sliding cavity is provided with an electromagnet 3113;

[0035] Two symmetrically distributed sliding rods 3110 are fixedly connected to the bottom of the connecting plate 3111 , a connecting rope 3109 is fixedly connected to the surface of the connecting rod 3107 , and the other end of the connecting rope 3109 is fixedly connected to the surface of the adjacent sliding rod 3110 .

[0036] By driving the knocking rod 3102 to knock on the surface of the anchor 201, its elastic wave is transmitted to the sensor 303 through the mounting seat 3101. After the sensor 303 detects the elastic wave, it is transmitted to the monitoring instrument body 1 through the transmission module 302, which is convenient for the staff to check the changes in the prestress of the concrete component. During the installation of the anchor 201, the position of the mounting plate 301 is positioned in conjunction with the anchor pad 2 to achieve the effect of long-term monitoring and avoid the magnetic suction seat of traditional detection from falling off due to vibration during construction.

[0037] By starting the electromagnet 3113, suction can be generated to drive the adsorption block 3112 to move upward. In this process, the connecting plate 3111 connected thereto can be driven to move upward synchronously, so that the connecting rope 3109 can be driven to move upward synchronously through the sliding rod 3110. Under the action of the guide wheel 3108, the connecting rod 3107 can be driven to rotate around the rotating block 3106, and at the same time, the rotating block 3106 can be driven to rotate the rotating shaft 3104. In this process, the mainspring 3105 can be tightened and as the rotating shaft 3104 rotates, the striking rod 3102 can be driven to rotate and deviate away from the surface of the anchor 201 until the electromagnet 3113 loses power and loses its power. Demagnetization force, at this time, under the action of the first spring 3115, the connecting plate 3111 is driven to reset quickly, and the pulling effect of the connecting rope 3109 on the connecting rod 3107 is released, so that the rotating shaft 3104 and the knocking rod 3102 can be reset under the action of the spring 3105. In this process, the knocking rod 3102 can be driven to reset and knock on the surface of the anchor 201, so as to transmit elastic waves for the sensor 303 to detect. Compared with the traditional method that requires manual knocking by staff, this method only needs to regularly turn on and off the power of the electromagnet 3113 to achieve automatic detection, which is beneficial to the long-term monitoring of prestressed concrete components.

[0038] like Figure 1-Figure 9 As shown, the other end of the mainspring 3105 is fixedly connected to the inner wall of the mounting plate 301, a first spring 3115 is fixedly connected between the top of the connecting plate 3111 and the inner wall of the sliding cavity, and the internal rotation of the mounting plate 301 is connected to a guide wheel 3108 for guiding the connecting rope 3109.

[0039] The mainspring 3105 is used to assist in resetting the rotating shaft 3104 after rotation, the first spring 3115 is used to assist in resetting the connecting plate 3111, and the guide wheel 3108 is used to reduce the wear of the connecting rope 3109 during movement.

[0040] like Figure 1-Figure 9 As shown, a rack 3123 is slidably connected to the surface of one of the slide bars 3110, a second spring 3125 is fixedly connected between the surface of the rack 3123 and the inner wall of the slide bar 3110, a slide bar 3126 is fixedly connected to the surface of the rack 3123, a guide groove 3103 is provided inside the mounting plate 301, and the cross-section of the guide groove 3103 is a right-angled triangle, a transverse groove is provided on the surface of the slide bar 3110, and the other end of the slide bar 3126 passes through the transverse groove and is slidably connected to the inner wall of the guide groove 3103.

[0041] The inner wall of the mounting plate 301 is rotatably connected to a trigger plate 3119, one side of the mounting seat 3101 is fixedly connected to a mounting rod 3114, the other end of the mounting rod 3114 passes through the interior of the mounting plate 301 and is fixedly connected to a connecting seat 3120 which is slidably connected to the inner wall of the mounting plate 301, one end of the trigger plate 3119 is rotatably connected to the surface of the connecting seat 3120, and a third spring 3127 is fixedly connected between the mounting rod 3114 and the inner wall of the mounting plate 301.

[0042] The inner wall of the mounting plate 301 is rotatably connected with a gear 3124, which is meshed with the rack 3123. A rotating plate 3122 is fixedly connected to one side of the gear 3124, and a trigger rod 3121 is fixedly connected to the other side of the rotating plate 3122. The surface of the trigger rod 3121 contacts the surface of the trigger plate 3119.

[0043] A liquid storage chamber 3116 is provided inside the mounting seat 3101, and the interior of the liquid storage chamber 3116 is filled with a coupling agent. A contact chamber connected to the liquid storage chamber 3116 is provided at the bottom of the mounting seat 3101, and two symmetrically distributed partitions 3117 are fixedly connected to the inner wall of the contact chamber, and the surface of the partition 3117 is provided with evenly distributed through holes 3118. A contact groove is provided on the bottom surface of the contact chamber, and the coupling agent can be filled in the contact groove to contact the surface of the anchor 201.

[0044] The coupling agent can enter the contact cavity to increase the transmission effect of the elastic wave, facilitate the sensor 303 to receive, and improve the detection effect. However, the effect of the coupling agent will decrease after long-term use, so it needs to be replaced regularly.

[0045] When the electromagnet 3113 is energized to adsorb the adsorption block 3112, the connecting plate 3111 and the sliding rod 3110 can be driven to move upward synchronously. At this time, the rack 3123 can be driven to make the gear 3124 rotate a quarter of a circle, so that the gear 3124 drives the rotating plate 3122 to rotate synchronously. During the resetting process of the sliding rod 3110, the sliding rod 3126 is guided by the guide groove 3103 so that the rack 3123 slides along the surface of the sliding rod 3110, thereby separating from the gear 3124. Therefore, during the resetting process, the gear 3124 will not be driven to be reset, so as to achieve the effect of one-way rotation of the gear 3124. After resetting to the right position, the rack 3123 can be driven to be reset and re-engaged with the gear 3124 under the action of the second spring 3125, so as to facilitate the next trigger to drive the gear 3124 to rotate.

[0046] The second spring 3125 is in a stretched state under normal conditions, so that after the sliding rod 3126 slides to the highest point, the sliding rod 3126 is pulled by the second spring 3125 to move along the right angle side of the guide groove 3103. For details, refer to Figure 4 , from the attached Figure 4 It can be seen that the hypotenuse of the guide groove 3103 is in a vertical state, and the guide groove 3103 is opened in a right-angled triangle. It can be seen that the two right-angled sides of the guide groove 3103 can drive the sliding rod 3126 to return to the position where the hypotenuse is opened during the downward movement of the sliding rod 3110 and re-stretch the second spring 3125 for re-triggering. The opening of the transverse groove is used to limit the moving direction of the sliding rod 3126, so as to facilitate the adjustment of the position of the rack 3123 in cooperation with the guide groove 3103 and the second spring 3125.

[0047] During the rotation of the rotating plate 3122, the trigger plate 3119 can be pushed to rotate by the trigger rod 3121, thereby driving the connecting seat 3120 connected thereto to drive the mounting rod 3114 to temporarily separate the mounting seat 3101 from the anchor 201. At this time, the used coupling agent in the contact cavity will flow out until the trigger rod 3121 is no longer in contact with the trigger plate 3119. The mounting rod 3114 can be driven to reset under the action of the third spring 3127. At this time, the coupling agent in the liquid storage cavity 3116 flows into the interior of the contact cavity under the influence of gravity, so as to replenish the space formed by the lost coupling agent in the contact cavity and ensure a good coupling effect of the contact surface. The setting of the partition 3117 and the through hole 3118 can make the coupling agent pass through the partition 3117 and gradually diffuse into the interior of the contact cavity, so as to ensure that the coupling agent at the center is always unused and a good conduction effect is ensured.

[0048] Refer to the attached Figure 3 It can be seen that the moving direction of the mounting rod 3114 is limited by the sliding groove provided on the mounting plate 301, so that the trigger plate 3119 is driven by the trigger rod 3121 to rotate counterclockwise, driving the mounting rod 3114 and the connecting seat 3120 to tilt upward, and the opening width of the sliding groove is slightly larger than the diameter of the connecting seat 3120, so that the mounting seat 3101 can be driven to separate from the anchor 201. In addition, the rotation angle of the trigger plate 3119 driven by the rotating plate 3122 through the trigger rod 3121 is not large, so that the mounting seat 3101 can be driven to tilt upward slightly to achieve the effect of separating from the anchor 201 without causing jamming.

[0049] For details, please refer to the attached Figure 8 It can be seen that the partition 3117 separates the contact cavity into three cavities, and the interior of the liquid storage cavity 3116 is connected to the middle cavity formed by the separation. This makes it possible for the coupling agent used in the original contact cavity to flow from the middle to both sides when the mounting seat 3101 is separated from the anchor 201 because the anchor 201 is cylindrical. After the mounting seat 3101 is separated, the coupling agent in the liquid storage cavity 3116 can be injected into the middle cavity to accelerate the discharge of the old coupling agent. After the mounting seat 3101 is reset, the newly added coupling agent can be injected from the through hole 3118 into the other two cavities formed by the separation, ensuring a good conduction effect.

[0050] Since the gear 3124 rotates a quarter turn each time, the coupling agent is replenished only after four tests, so there is no need to worry about the coupling agent being wasted.

[0051] Working principle: By starting the electromagnet 3113, suction can be generated to drive the adsorption block 3112 to move upward. In this process, the connecting plate 3111 connected thereto can be driven to move upward synchronously, so that the connecting rope 3109 can be driven to move upward synchronously through the sliding rod 3110. Under the action of the guide wheel 3108, the connecting rod 3107 can be driven to rotate around the rotating block 3106, and at the same time, the rotating block 3106 can be driven to rotate the rotating shaft 3104. In this process, the mainspring 3105 can be tightened and the striking rod 3102 can be driven to rotate and deviate away from the surface of the anchor 201 as the rotating shaft 3104 rotates, until the electromagnet 3113 loses its magnetic force after power is turned off. At this time, under the action of the first spring 3115, the connecting plate 3111 is driven to reset quickly, and the pulling effect of the connecting rope 3109 on the connecting rod 3107 is released, so that Under the action of the clockwork 3105, the rotating shaft 3104 and the knocking rod 3102 are driven to reset. In this process, the knocking rod 3102 can be driven to reset and knock on the surface of the anchor 201, so as to transmit elastic waves for the sensor 303 to detect. Compared with the traditional method that requires manual knocking by staff, this method only needs to regularly turn on and off the power of the electromagnet 3113 to achieve automatic detection, which is beneficial to the long-term monitoring of the prestressed concrete components. After the sensor 303 detects the elastic wave, it is transmitted to the monitoring instrument body 1 through the transmission module 302 for the convenience of staff to check the changes in the prestressed concrete components. During the installation of the anchor 201, the position of the mounting plate 301 is positioned in cooperation with the anchor pad 2 to achieve the effect of long-term monitoring and avoid the situation where the magnetic suction seat of the traditional detection is affected by vibration and falls off during the construction process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
