A device for measuring the thickness of polymer cement waterproof coating

Abstract

The invention relates to the technical field of cement waterproof coating thickness measuring equipment and discloses a polymer cement waterproof coating thickness measuring device, comprising a measuring instrument, wherein a transmission line is fixedly connected to the bottom of the measuring instrument, and a fixed rod is fixedly connected to the end of the transmission line away from the measuring instrument. The sliding rod forces a piston plate to slide upward along the inner wall of a hydraulic box, so that a spring 1 is compressed and deformed. After the probe completes the measurement, when the fixed rod is recovered, it is ensured that the probe faces upward. As the sliding rod is no longer compressed, the spring 1 will release the pressure it receives, forcing the piston plate to move in the direction of an L-shaped transmission tube 1. At this time, anhydrous ethanol at the bottom of the piston plate is squeezed by the spring 1, transmitted to the inside of an atomizer through the L-shaped transmission tube 1, and finally sprayed outward from multiple spray heads, ensuring that the anhydrous ethanol sprayed outward from the multiple spray heads can shield the probe after each detection, thereby reducing the total amount of dust adhering to the outer wall of the probe during the process of transferring the measurement position.

Description

Technical Field

[0001] The invention relates to the technical field of cement waterproof coating thickness measuring equipment, in particular to a polymer cement waterproof coating thickness measuring device. Background Art

[0002] Polymer cement waterproof coating, abbreviated as JS waterproof coating, J refers to polymer, S refers to cement, so JS is polymer cement waterproof coating. Polymer cement waterproof coating is an organic liquid composed of polymer emulsions such as polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and various additives. Polymer cement waterproof coating is an inorganic powder composed of cement, quartz sand, light and heavy calcium carbonate and other inorganic fillers and various additives through reasonable proportioning and compounding. A two-component, water-based building waterproof coating is made. After applying polymer cement waterproof coating, its thickness needs to be measured. The commonly used coating thickness measuring equipment is an ultrasonic thickness gauge.

[0003] When applying cement waterproof coating, the surface of the cement board is quite undulating, which requires conventional instruments to measure at different locations and then take the middle value as the basic data. However, during multiple measurements, due to the high dust content in the air at the construction site, the coupling agent remaining on the outer wall of the probe will adhere to some fine dust, causing errors in the test data. To address the above problems, the following solution is proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a polymer cement waterproof coating thickness measuring device, comprising a measuring instrument, a transmission line fixedly connected to the bottom of the measuring instrument, a fixed rod fixedly connected to the end of the transmission line away from the measuring instrument, and a mounting plate fixedly connected to the end of the fixed rod away from the transmission line. The specific model of the measuring instrument is: Defus high coating thickness gauge;

[0005] The protection mechanism includes a probe, a hydraulic box for protecting the probe, a sliding rod, a piston plate, and a drive assembly for atomizing the liquid inside the hydraulic box;

[0006] The bottom of the mounting plate is fixedly connected to the outer wall of the probe, the outer wall of the mounting plate is fixedly connected to the outer walls of the four hydraulic boxes, the inner walls of the four hydraulic boxes are slidably connected to the outer wall of the sliding rod, the outer wall of the sliding rod is fixedly connected to the outer wall of the piston plate, and the outer wall of the piston plate is slidably connected to the inner wall of the hydraulic box.

[0007] Preferably, the drive assembly includes a spring 1 fixedly connected to the top of the piston plate, the end of the spring 1 away from the piston plate is fixedly connected to the inner wall of the hydraulic box, two L-shaped transmission tubes 1 are connected through the side walls of the four hydraulic boxes, and the ends of the two L-shaped transmission tubes 1 away from the hydraulic box are connected through an atomizer. Before use, make sure that the storage box and the hydraulic box are filled with anhydrous ethanol. The staff holds the measuring instrument in one hand and the handle in the other hand. After cleaning the required detection area, the staff points the probe downward and squeezes it downward to force the probe to contact the outer wall of the cement.

[0008] Preferably, the driving assembly also includes a spray head fixedly connected to one end of the L-shaped transmission tube away from the several atomizers, a storage box is fixedly connected to the outer wall of the four hydraulic boxes, a grasping frame is fixedly connected to the outer wall of the storage box, and a blocking assembly is fixedly connected to the outer wall of the hydraulic box. The sliding rod first contacts the outer wall of the cement, and the sliding rod forces the piston plate to slide upward along the inner wall of the hydraulic box, so that the spring 1 is compressed and deformed. After the probe completes the measurement, when the fixed rod is recovered, ensure that the probe is facing upward. In this process, as the sliding rod is no longer compressed, the spring 1 will release the pressure it receives, forcing the piston plate to move toward the direction of the L-shaped transmission tube 1, presenting a Figure 4 At this time, the anhydrous ethanol at the bottom of the piston plate is squeezed by the spring 1, transmitted to the inside of the atomizer through the L-shaped transmission tube 1, and finally sprayed out from multiple nozzles. Through the application of the above components, it is ensured that after each probe completes detection, the anhydrous ethanol sprayed out by the multiple nozzles can shield the probe, reducing the total amount of dust adhering to the outer wall of the probe during the process of transferring the measurement position, thereby improving the detection accuracy of the equipment.

[0009] Preferably, the blocking assembly includes two blocking plates fixedly connected to the outer wall of the hydraulic box, a slide groove is provided on the inner wall of the blocking plate, the inner wall of the slide groove is connected to the inner wall of the hydraulic box, and the inner wall of the slide groove is connected to the inner wall of the L-shaped transmission pipe. Taking advantage of the fact that one end of the above-mentioned measuring probe is always facing downward, a blocking assembly is provided inside the equipment. When the equipment completes the detection, it is necessary to ensure that the probe is facing upward. During this process, the sliding plate moves toward the direction of the probe under the influence of gravity, presenting a Figure 8 At this time, the through hole groove 1 will coincide with the through hole of the hydraulic box, and the anhydrous ethanol inside the hydraulic box can be directly transmitted to the spray head through the above overlapping gap, thereby achieving the effect of anhydrous ethanol atomization protecting the probe.

[0010] Preferably, the blocking component also includes a sliding plate slidably connected to the inner wall of the slide groove, a through hole groove 1 is opened on the side wall of the sliding plate, and a low-speed component is provided on the inner wall of the mounting plate. When the probe is facing downward, the sliding plate will slide again along the inner wall of the slide groove, so that the sliding plate blocks the flow path between the L-shaped transmission tube 1 and the hydraulic box, so that the anhydrous ethanol inside the hydraulic box cannot be sprayed outward through the atomizer again. Through the application of the above-mentioned components, it is avoided that when the equipment is aligned with the test position, the nozzle head continuously sprays out atomized anhydrous ethanol, causing the anhydrous ethanol to mix with the coupling agent on the ground, affecting the ultrasonic transmission efficiency of the equipment.

[0011] Preferably, the low-speed component includes a hydraulic pipe fixedly connected to the inner wall of the mounting plate, a piston block is slidably connected to the inner wall of the hydraulic pipe, a pulling rod is fixedly connected to the top of the piston block, and the end of the pulling rod away from the piston block is fixedly connected to the bottom of the piston plate. Utilizing the characteristic that the above-mentioned piston plate moves up and down on the inner wall of the hydraulic box, a low-speed component is provided inside the equipment. When the sliding rod pushes the piston plate to move upward, the piston plate drives the piston block to move upward along the inner wall of the hydraulic pipe through the pulling rod, wherein the interior of the hydraulic pipe is filled with hydraulic oil, presenting a Figure 9 status.

[0012] Preferably, the low-speed component also includes three through-hole grooves 2 opened on the top of the piston block, the inner walls of the three through-hole grooves 2 are provided with right-angle grooves, the inner walls of the right-angle grooves are rotatably connected with a rotating plate, the inner walls of the through-hole grooves 2 are fixedly connected with a limiting column, and a supplementary component is provided on the inner wall of the hydraulic box. As the piston block moves upward, the hydraulic oil on the top of the piston block will reach the bottom of the piston block through the through-hole grooves 2. When the hydraulic oil passes through the through-hole grooves 2, the hydraulic oil from top to bottom will force the rotating plate to rotate downward, presenting a Figure 10 In the middle G state, the gap between the two rotating plates is relatively large, and the piston block moves up faster. As the spring 1 releases the mechanical force and forces the piston plate to slide downward, the liquid at the bottom of the piston block will flow upward again through the through-hole groove 2. At this time, the flowing hydraulic oil will drive the two rotating plates to rotate upward, causing the gap formed by the two rotating plates to shrink, slowing down the circulation efficiency of the hydraulic oil, increasing the resistance to the downward movement of the piston plate, and slowing down the downward movement of the piston plate. Through the application of the above components, it is avoided that after the equipment is away from the cement surface, the atomized anhydrous ethanol is immediately sprayed out through the nozzle, causing the atomized anhydrous ethanol to carry the dust remaining on the surface to fly, causing pollution to the outer wall of the probe.

[0013] Preferably, the supplementary component includes a mounting column fixedly connected to the inner wall of the hydraulic box, the inner wall of the mounting column is provided with an inclined groove 1, the inner wall of the inclined groove 1 is connected through an L-shaped transmission pipe 2, and the inner wall of the inclined groove 1 is fixedly connected to a bracket 1, wherein Figure 1 The F position in the middle is a one-way water inlet pipe, and the staff can fill anhydrous ethanol into the storage box through F.

[0014] Preferably, the supplementary component also includes a sliding rod 1 slidably connected to the inner wall of the bracket 1, a blocking block 1 is fixedly connected to the top of the sliding rod 1, a spring 4 is fixedly connected to the side wall of the sliding rod 1, and the end of the spring 4 away from the sliding rod 1 is fixedly connected to the side wall of the bracket 1. When the piston plate moves downward, as the space between the bottom of the piston plate and the hydraulic tank increases, negative pressure is generated, and the negative pressure will force the blocking block 1 to slide downward along the inner wall of the bracket 1. At this time, the anhydrous ethanol on the inner wall of the storage box will pass through the L-shaped transmission pipe 2, and then fill the gap between the blocking block 1 and the inclined groove 1 to the inner wall of the hydraulic tank, and accumulate on the top of the piston plate.

[0015] Preferably, the supplementary component also includes an inclined groove 2 opened on the top of the piston plate, a bracket 2 is fixedly connected to the inner wall of the inclined groove 2, a sliding rod 2 is slidably connected to the inner wall of the bracket 2, a spring 5 is fixedly connected to the outer wall of the sliding rod 2, and a blocking block 2 is fixedly connected to the top of the sliding rod 2. When the piston plate moves upward, the anhydrous ethanol at the top of the piston plate will flow into the bottom of the piston plate through the gap between the blocking block 2 and the inclined groove 2, so that the anhydrous ethanol at the bottom of the piston plate is in a state to be sprayed. Through the application of the above components, the autonomous filling of the equipment is realized and the detection speed of the equipment is improved.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention utilizes the characteristic that each time the probe is tested, it is necessary to press hard to reduce the gap between the probe and the surface of the coating. Before use, ensure that the storage box and the hydraulic box are filled with anhydrous ethanol. The staff holds the measuring instrument in one hand and the handle in the other hand. After cleaning the required test area, the staff points the probe downward and squeezes it downward to force the probe to contact the outer wall of the cement. During this process, the sliding rod first contacts the outer wall of the cement, and the sliding rod forces the piston plate to slide upward along the inner wall of the hydraulic box, causing the spring 1 to be compressed and deformed. After the probe completes the measurement, when the fixed rod is retracted, ensure that the probe is facing upward. During this process, as the sliding rod is no longer compressed, the spring 1 will release the pressure it receives, forcing the piston plate to move in the direction of the L-shaped transmission tube 1, as shown in the following figure. Figure 4 At this time, the anhydrous ethanol at the bottom of the piston plate is squeezed by the spring 1, transmitted to the inside of the atomizer through the L-shaped transmission tube 1, and finally sprayed out from multiple nozzles. Through the application of the above components, it is ensured that after each probe completes detection, the anhydrous ethanol sprayed out by the multiple nozzles can shield the probe, reducing the total amount of dust adhering to the outer wall of the probe during the process of transferring the measurement position, thereby improving the detection accuracy of the equipment.

[0018] (2) The present invention utilizes the characteristics of the piston plate moving up and down on the inner wall of the hydraulic box, and a low-speed component is set inside the device. When the sliding rod pushes the piston plate to move upward, the piston plate drives the piston block to move upward along the inner wall of the hydraulic pipe through the pulling rod, and the hydraulic pipe is filled with hydraulic oil, showing a Figure 9 As the piston moves upward, the hydraulic oil on the top of the piston will pass through the through-hole groove 2 to the bottom of the piston. When the hydraulic oil passes through the through-hole groove 2, the hydraulic oil from top to bottom will force the rotating plate to rotate downward, showing Figure 10 In the middle G state, the gap between the two rotating plates is relatively large, and the piston block moves up faster. As the spring 1 releases the mechanical force and forces the piston plate to slide downward, the liquid at the bottom of the piston block will flow upward again through the through-hole groove 2. At this time, the flowing hydraulic oil will drive the two rotating plates to rotate upward, causing the gap formed by the two rotating plates to shrink, slowing down the circulation efficiency of the hydraulic oil, increasing the resistance to the downward movement of the piston plate, and slowing down the downward movement of the piston plate. Through the application of the above components, it is avoided that after the equipment is away from the cement surface, the atomized anhydrous ethanol is immediately sprayed out through the nozzle, causing the atomized anhydrous ethanol to carry the dust remaining on the surface to fly, causing pollution to the outer wall of the probe.

[0019] (3) The present invention utilizes the characteristic that one end of the measuring probe is always facing downwards, and a blocking component is provided inside the device. When the device completes the detection, it is necessary to ensure that the probe is facing upwards. During this process, the sliding plate moves toward the probe under the influence of gravity, presenting the following Figure 8 When the probe is facing downward, the sliding plate will slide again along the inner wall of the slide groove, so that the sliding plate blocks the flow path between the L-shaped transmission pipe 1 and the hydraulic box, so that the anhydrous ethanol in the hydraulic box cannot be sprayed out through the atomizer again. By applying the above components, it is avoided that the nozzle head continuously sprays out atomized anhydrous ethanol when the equipment is aligned with the test position, resulting in the mixing of anhydrous ethanol and the coupling agent on the ground, which affects the ultrasonic transmission efficiency of the equipment.

[0020] (4) The present invention utilizes the characteristic of the piston plate that squeezes the liquid inside the hydraulic box downward, and a supplementary component is provided inside the device. When the piston plate moves downward, as the space between the bottom of the piston plate and the hydraulic box increases, negative pressure is generated, and the negative pressure will force the blocking block 1 to slide downward along the inner wall of the bracket 1. At this time, the anhydrous ethanol on the inner wall of the storage box will pass through the L-shaped transmission pipe 2, and then fill the gap between the blocking block 1 and the inclined groove 1 to the inner wall of the hydraulic box, and accumulate on the top of the piston plate; and when the piston plate moves upward, the anhydrous ethanol at the top of the piston plate will flow through the gap between the blocking block 2 and the inclined groove 2 into the bottom of the piston plate, so that the anhydrous ethanol at the bottom of the piston plate is in a state to be sprayed out. Through the application of the above components, the self-filling of the device is realized, and the detection speed of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] For example 1, please refer to Figure 1 - Figure 6 The present invention is a device for measuring the thickness of a polymer cement waterproof coating, comprising a measuring instrument 1, a transmission line 11 being fixedly connected to the bottom of the measuring instrument 1, a fixing rod 12 being fixedly connected to the end of the transmission line 11 away from the measuring instrument 1, and a mounting plate 13 being fixedly connected to the end of the fixing rod 12 away from the transmission line 11. The specific model of the measuring instrument 1 is: Defus high coating thickness gauge;

[0039] The protection mechanism 2 includes a probe 21, a hydraulic box 22 for protecting the probe 21, a sliding rod 23, a piston plate 24, and a drive assembly 3 for atomizing the liquid inside the hydraulic box 22;

[0040] The bottom of the mounting plate 13 is fixedly connected to the outer wall of the probe 21, the outer wall of the mounting plate 13 is fixedly connected to the outer walls of the four hydraulic boxes 22, the inner walls of the four hydraulic boxes 22 are slidably connected to the outer wall of the sliding rod 23, the outer wall of the sliding rod 23 is fixedly connected to the outer wall of the piston plate 24, and the outer wall of the piston plate 24 is slidably connected to the inner wall of the hydraulic box 22.

[0041] The driving assembly 3 includes a spring 31 fixedly connected to the top of the piston plate 24. The end of the spring 31 away from the piston plate 24 is fixedly connected to the inner wall of the hydraulic box 22. Two L-shaped transmission tubes 32 are connected through the side walls of the four hydraulic boxes 22. The ends of the two L-shaped transmission tubes 32 away from the hydraulic box 22 are connected through an atomizer 33. Before use, make sure that the storage box 35 and the inside of the hydraulic box 22 are filled with anhydrous ethanol. The staff holds the measuring instrument 1 in one hand and the grasping frame 36 in the other hand. After cleaning the required detection area, the staff points the probe 21 downward and squeezes it downward to force the probe 21 to contact the outer wall of the cement.

[0042] The driving assembly 3 also includes a spray head 34 fixedly connected to a plurality of atomizers 33 away from one end of the L-shaped transmission tube 32. The outer walls of the four hydraulic boxes 22 are fixedly connected to the storage boxes 35. The outer walls of the storage boxes 35 are fixedly connected to the grasping frame 36. The outer wall of the hydraulic box 22 is fixedly connected to the blocking assembly 4. The sliding rod 23 first contacts the outer wall of the cement. The sliding rod 23 forces the piston plate 24 to slide upward along the inner wall of the hydraulic box 22, so that the spring 31 is compressed and deformed. After the probe 21 completes the measurement, when the fixed rod 12 is recovered, ensure that the probe 21 is facing upward. In this process, as the sliding rod 23 is no longer compressed, the spring 31 will release the pressure and force the piston plate 24 to move toward the direction of the L-shaped transmission tube 32, as shown in the following figure. Figure 4 At this time, the anhydrous ethanol at the bottom of the piston plate 24 is squeezed by the spring 1 31, transmitted to the inside of the atomizer 33 through the L-shaped transmission tube 1 32, and finally sprayed out from the multiple spray heads 34. Through the application of the above components, it is ensured that after each detection by the probe 21, the anhydrous ethanol sprayed outward by the multiple spray heads 34 can shield the probe 21, thereby reducing the total amount of dust adhering to the outer wall of the probe 21 during the process of transferring the measurement position, thereby improving the detection accuracy of the equipment.

[0043] For example 2, please refer to Figure 7 - Figure 13The present invention is a device for measuring the thickness of a polymer cement waterproof coating. Based on Example 1, the blocking component 4 includes two blocking plates 41 fixedly connected to the outer wall of the hydraulic box 22. A slide groove 42 is provided on the inner wall of the blocking plate 41. The inner wall of the slide groove 42 is connected to the inner wall of the hydraulic box 22, and the inner wall of the slide groove 42 is connected to the inner wall of the L-shaped transmission pipe 32. Taking advantage of the fact that one end of the above-mentioned measuring probe 21 is always facing downward, a blocking component 4 is provided inside the device. When the device completes the detection, it is necessary to ensure that the probe 21 is facing upward. During this process, the sliding plate 43 moves toward the direction of the probe 21 under the influence of gravity, presenting the following Figure 8 state, at this time the through hole groove 44 will coincide with the through hole of the hydraulic box 22, and the anhydrous ethanol inside the hydraulic box 22 can be directly transmitted to the spray head 34 through the above overlapping gap, thereby achieving the effect of anhydrous ethanol atomization protecting the probe 21.

[0044] The blocking component 4 also includes a sliding plate 43 that is slidably connected to the inner wall of the slide groove 42. A through hole groove 44 is opened on the side wall of the sliding plate 43. A low-speed component 5 is provided on the inner wall of the mounting plate 13. When the probe 21 is facing downward, the sliding plate 43 will slide again along the inner wall of the slide groove 42, so that the sliding plate 43 blocks the flow path between the L-shaped transmission tube 32 and the hydraulic box 22, so that the anhydrous ethanol in the hydraulic box 22 cannot be sprayed out through the atomizer 33 again. Through the application of the above components, it is avoided that when the equipment is aligned with the test position, the nozzle 34 continuously sprays out atomized anhydrous ethanol, causing the anhydrous ethanol to mix with the coupling agent on the ground, affecting the ultrasonic transmission efficiency of the equipment.

[0045] The low-speed component 5 includes a hydraulic pipe 51 fixedly connected to the inner wall of the mounting plate 13, a piston block 52 is slidably connected to the inner wall of the hydraulic pipe 51, a pulling rod 53 is fixedly connected to the top of the piston block 52, and the end of the pulling rod 53 away from the piston block 52 is fixedly connected to the bottom of the piston plate 24. Taking advantage of the fact that the piston plate 24 moves up and down on the inner wall of the hydraulic box 22, a low-speed component 5 is provided inside the equipment. When the sliding rod 23 pushes the piston plate 24 to move upward, the piston plate 24 drives the piston block 52 to move upward along the inner wall of the hydraulic pipe 51 through the pulling rod 53, wherein the interior of the hydraulic pipe 51 is filled with hydraulic oil, presenting a Figure 9 status.

[0046] The low-speed component 5 also includes three through-hole grooves 54 opened on the top of the piston block 52. The inner walls of the three through-hole grooves 54 are provided with right-angle grooves 55. The inner walls of the right-angle grooves 55 are rotatably connected to a rotating plate 56. The inner walls of the through-hole grooves 54 are fixedly connected to a limiting column 57. A supplementary component 6 is provided on the inner wall of the hydraulic box 22. As the piston block 52 moves upward, the hydraulic oil at the top of the piston block 52 will reach the bottom of the piston block 52 through the through-hole grooves 54. When the hydraulic oil passes through the through-hole grooves 54, the hydraulic oil from top to bottom will force the rotating plate 56 to rotate downward, presenting a Figure 10 In the middle G state, the gap between the two rotating plates 56 is relatively large, and the piston block 52 moves up faster. As the spring 1 31 releases the mechanical force and forces the piston plate 24 to slide downward, the liquid at the bottom of the piston block 52 will flow upward again through the through-hole groove 2 54. At this time, the flowing hydraulic oil will drive the two rotating plates 56 to rotate upward, so that the gap formed by the two rotating plates 56 is reduced, the circulation efficiency of the hydraulic oil is slowed down, and the resistance to the downward movement of the piston plate 24 is increased, so that the speed of the piston plate 24 moving downward is slowed down. Through the application of the above-mentioned components, it is avoided that after the equipment is away from the cement surface, the atomized anhydrous ethanol is immediately sprayed out through the nozzle 34, causing the atomized anhydrous ethanol to carry the dust remaining on the surface to fly, causing pollution to the outer wall of the probe 21.

[0047] The supplementary component 6 includes a mounting column 61 fixedly connected to the inner wall of the hydraulic box 22, an inclined groove 62 is opened on the inner wall of the mounting column 61, an L-shaped transmission pipe 63 is connected to the inner wall of the inclined groove 62, and a bracket 64 is fixedly connected to the inner wall of the inclined groove 62. Figure 1 The F position in the middle is a one-way water inlet pipe, and the staff can fill anhydrous ethanol into the storage box 35 through F.

[0048] The supplementary component 6 also includes a sliding rod 65 slidably connected to the inner wall of the bracket 64, and a blocking block 66 is fixedly connected to the top of the sliding rod 65. A spring four 67 is fixedly connected to the side wall of the sliding rod 65. The end of the spring four 67 away from the sliding rod 65 is fixedly connected to the side wall of the bracket 64. When the piston plate 24 moves downward, as the space between the bottom of the piston plate 24 and the hydraulic tank 22 increases, negative pressure is generated, and the negative pressure will force the blocking block 66 to slide downward along the inner wall of the bracket 64. At this time, the anhydrous ethanol on the inner wall of the storage box 35 will pass through the L-shaped transmission pipe 263, and then fill the gap between the blocking block 66 and the inclined groove 62 to the inner wall of the hydraulic tank 22, and accumulate on the top of the piston plate 24.

[0049] The supplementary component 6 also includes an inclined groove 2 612 opened on the top of the piston plate 24, a bracket 2 68 is fixedly connected to the inner wall of the inclined groove 2 612, a sliding rod 2 69 is slidably connected to the inner wall of the bracket 2 68, a spring 5 610 is fixedly connected to the outer wall of the sliding rod 2 69, and a blocking block 2 611 is fixedly connected to the top of the sliding rod 2 69. When the piston plate 24 moves upward, the anhydrous ethanol at the top of the piston plate 24 will flow into the bottom of the piston plate 24 through the gap between the blocking block 2 611 and the inclined groove 2 612, so that the anhydrous ethanol at the bottom of the piston plate 24 is in a state to be sprayed. Through the application of the above components, the autonomous filling of the equipment is realized and the detection speed of the equipment is improved.

[0050] A specific application of this embodiment is: before use, ensure that the storage box 35 and the hydraulic box 22 are filled with anhydrous ethanol, the staff holds the measuring instrument 1 with one hand and the grasping frame 36 with the other hand, and after cleaning the position of the required detection area, the staff points the probe 21 downward and squeezes downward to force the probe 21 to contact the outer wall of the cement. During this process, the sliding rod 23 first contacts the outer wall of the cement, and the sliding rod 23 forces the piston plate 24 to slide upward along the inner wall of the hydraulic box 22, so that the spring 1 31 is compressed and deformed. After the probe 21 completes the measurement, when the fixed rod 12 is recovered, ensure that the probe 21 is facing upward. During this process, as the sliding rod 23 is no longer compressed, the spring 1 31 will release the pressure, forcing the piston plate 24 to move toward the direction of the L-shaped transmission tube 1 32, as shown in the following figure Figure 4 At this time, the anhydrous ethanol at the bottom of the piston plate 24 is squeezed by the spring 1 31, transmitted to the inside of the atomizer 33 through the L-shaped transmission tube 1 32, and finally sprayed out from the multiple spray heads 34. Through the application of the above components, it is ensured that after each detection by the probe 21, the anhydrous ethanol sprayed outward by the multiple spray heads 34 can shield the probe 21, thereby reducing the total amount of dust adhering to the outer wall of the probe 21 during the process of transferring the measurement position, thereby improving the detection accuracy of the equipment.

[0051] Taking advantage of the fact that the piston plate 24 moves up and down on the inner wall of the hydraulic box 22, a low-speed component 5 is provided inside the device. When the sliding rod 23 pushes the piston plate 24 to move upward, the piston plate 24 drives the piston block 52 to move upward along the inner wall of the hydraulic pipe 51 through the pulling rod 53, wherein the hydraulic pipe 51 is filled with hydraulic oil, presenting a Figure 9 As the piston block 52 moves upward, the hydraulic oil on the top of the piston block 52 will reach the bottom of the piston block 52 through the second through-hole groove 54. When the hydraulic oil passes through the second through-hole groove 54, the hydraulic oil from top to bottom will force the rotating plate 56 to rotate downward, presenting a Figure 10In the middle G state, the gap between the two rotating plates 56 is relatively large, and the piston block 52 moves up faster. As the spring 1 31 releases the mechanical force and forces the piston plate 24 to slide downward, the liquid at the bottom of the piston block 52 will flow upward again through the through-hole groove 2 54. At this time, the flowing hydraulic oil will drive the two rotating plates 56 to rotate upward, so that the gap formed by the two rotating plates 56 is reduced, the circulation efficiency of the hydraulic oil is slowed down, and the resistance to the downward movement of the piston plate 24 is increased, so that the speed of the piston plate 24 moving downward is slowed down. Through the application of the above-mentioned components, it is avoided that after the equipment is away from the cement surface, the atomized anhydrous ethanol is immediately sprayed out through the nozzle 34, causing the atomized anhydrous ethanol to carry the dust remaining on the surface to fly, causing pollution to the outer wall of the probe 21.

[0052] Taking advantage of the fact that one end of the measuring probe 21 is always facing downwards, a blocking component 4 is provided inside the device. When the device completes the test, it is necessary to ensure that the probe 21 is facing upwards. During this process, the sliding plate 43 moves towards the direction of the probe 21 under the influence of gravity, presenting the following situation: Figure 8 When the probe 21 is facing downward, the sliding plate 43 will slide again along the inner wall of the slide groove 42, so that the sliding plate 43 blocks the flow path between the L-shaped transmission tube 1 32 and the hydraulic tank 22, so that the anhydrous ethanol in the hydraulic tank 22 cannot be sprayed out through the atomizer 33 again. By using the above components, it is avoided that the spray head 34 continuously sprays out atomized anhydrous ethanol when the equipment is aligned with the test position, causing the anhydrous ethanol to mix with the coupling agent on the ground, thereby affecting the ultrasonic transmission efficiency of the equipment.

[0053] Taking advantage of the characteristic that the piston plate 24 squeezes the liquid inside the hydraulic tank 22 downward, a supplementary component 6 is provided inside the device. When the piston plate 24 moves downward, as the space between the bottom of the piston plate 24 and the hydraulic tank 22 increases, negative pressure is generated, and the negative pressure will force the blocking block 66 to slide downward along the inner wall of the bracket 64. At this time, the anhydrous ethanol on the inner wall of the storage box 35 will pass through the L-shaped transmission pipe 263, and then fill the gap between the blocking block 66 and the inclined groove 62 to the inner wall of the hydraulic tank 22, and accumulate on the top of the piston plate 24; and when the piston plate 24 moves upward, the anhydrous ethanol at the top of the piston plate 24 will flow into the bottom of the piston plate 24 through the gap between the blocking block 2611 and the inclined groove 2612, so that the anhydrous ethanol at the bottom of the piston plate 24 is in a state to be sprayed out. Through the application of the above components, the device can be filled autonomously and the detection speed of the device can be improved.
