[0028] By installing the mounting plate 5 on the end of the sensor body 1 close to the pressure interface 2, the first connecting rod 6 drives the mounting block 7 and the internal adjustment structure thereof to be installed on the top of the pressure interface 2, by placing the sealing ring 4 on the two clamping blocks 12 inside the fixing block 8, and then fitting the two sides of the fixing blocks 8 together, and then passing the pressure interface 2 through the fixing block 8, and then starting the first electric push rod 9 to push the fixing plate 10 and the second electric push rod 11 to move downward, so that the clamping block 12 drives the density ring to correspond to the sealing groove 3 at the pressure interface 2, and the second electric push rod 11 is installed through the fixing plate 10. When the first electric push rod 9 moves downward, it drives the fixing rod 13 and the first rack 14 to move, so that the first gear 15 rotates, and the second rack 16 drives the limiting block 17 to move upward, so that the connecting spring 18 is compressed, so that the limiting block 17 is away from the sealing ring 4, and then the second electric push rod 11 is started to push the clamping block 12 close The sealing groove 3 makes the sealing ring 4 close to the sealing groove 3. When the sealing ring 4 is close to the sealing block, the first electric push rod 9 is started again to drive the fixed plate 10, the second electric push rod 11 and the block 12 to move downward, so that the block 12 is separated from the sealing ring 4, and the sealing ring 4 is no longer limited. Under the action of elasticity, it shrinks toward the middle, so that the sealing ring 4 moves to the inside of the sealing groove 3. After the installation is completed, the block 12 is moved to the original position by the second electric push rod 11, and the first electric push rod 9 drives the fixed plate 10 and the second electric push rod 11, The block 12 moves upward to the inside of the fixed block 8. At the same time, through the action of the first rack 14, the first gear 15 and the second rack 16, the connecting spring 18 stretches and pushes the limiting block 17 to move downward to press and fix the sealing ring 4 inside the sealing groove 3, so that the sealing ring 4 and the pressure interface 2 remain sealed, which is convenient for the installation of the sealing ring 4 and the use of the grouting pressure sensor.

[0029] like Figures 4 to 7 As shown, a movable opening is opened in the middle of the mounting block 7, and the movable opening is arranged corresponding to the arc-shaped opening on one side of the two fixed blocks 8. A first magnetic block 21 is fixedly installed on the top of the movable block 19, and the bottom of the sealing ring 4 is located at the bottom of the two fixed blocks 8. An adjustment structure is arranged inside the mounting block 7, and slots 22 are opened on both sides of the bottom end of the mounting block 7. A plug rod 23 is fixedly installed on the top of the two fixed blocks 8, and the plug rod 23 is plugged into the slot 22.

[0030] The movable opening and the arc opening facilitate the sensor body 1 and the pressure interface 2 to pass through the mounting block 7 and the fixed block 8, and the mounting block 7 is fixed by the mounting plate 5 and the first connecting rod 6. When the sealing ring 4 is placed on the block 12 inside the fixed block 8, the two fixed blocks 8 are fitted on one side, and then the two fixed blocks 8 and the sealing ring 4 are moved upward as a whole, so that the insertion rod 23 at the top of the fixed block 8 is inserted into the slot 22 at the bottom of the mounting block 7, so that the fixed block 8 is installed and fixed at the bottom of the mounting block 7 and is located on the outside of the pressure interface 2. At the same time, when the sealing ring 4 is installed, it is connected to the adjustment structure through the first magnetic block 21, so that the adjustment structure drives the moving block 19 to move, and the limiting block 17 is driven to move on the top of the sealing ring 4 through the connecting spring 18, so that the sealing ring 4 remains flat inside the sealing groove 3, thereby facilitating the pressure interface 2 to maintain sealing and preventing leakage during use.

[0031] like Figure 6 As shown, a movable opening is opened on the top of the two fixed blocks 8, and a second connecting rod is rotatably connected to the inner wall of the movable opening. A baffle 24 is fixedly connected to the middle of the second connecting rod. The baffle 24 is located at the bottom of the fixed block 8 and at the movable opening. The baffle 24 is located on both sides of the sealing ring 4.

[0032] The movable opening can be exposed by rotating the baffle plate 24. Since the bottom of the sealing ring 4 is located at the bottom of the two fixed blocks 8, the first electric push rod 9 can push the fixed plate 10, the second electric push rod 11 and the bottom of the fixed block 8 to move through the movable opening, so that the sealing ring 4 on the clamping block 12 corresponds to the sealing groove 3, thereby facilitating the automatic installation of the sealing ring 4. When the installation is completed, the baffle plate 24 is rotated to cover the movable opening, thereby facilitating the shielding and protection of the inside of the fixed block 8, and facilitating the improvement of the service life of the first electric push rod 9, the second electric push rod 11, the clamping block 12, the first rack 14, the first gear 15, the second rack 16 and the limiting block 17 inside the fixed block 8.

[0033] like Figure 3 to Figure 4 As shown, the shape of the card block 12 is L-shaped, the card block 12 is located on one side of the limiting block 17, and it is located at the bottom of the fixing rod 13 and the first rack 14, the top of the first electric push rod 9 is fixedly installed on the top inner wall of the fixing block 8, and the middle of the first gear 15 is fixedly connected with a rotating rod, one end of the rotating rod is rotatably connected with a connecting plate, the top of the connecting plate is fixedly installed on the top inner wall of the fixing block 8, and the connecting plate is located on one side of the limiting block 17.

[0034] The L-shaped block 12 is used to limit the sealing ring 4, so that the sealing ring 4 is placed on the block 12 for easy installation. The first rack 14 is moved to drive the first gear 15 and the rotating rod to rotate, so that one end of the rotating rod rotates on one side of the connecting plate. The rotating rod is installed through the connecting plate, so that the rotating rod remains stable when rotating, thereby facilitating the second rack 16 to drive the limiting block 17 to move, so as to facilitate the sealing of the sealing ring 4 after installation.

[0035] like Figure 7 As shown, a socket is provided on one side of the two fixing blocks 8 that are close to each other, and the socket is located on one side of the mounting groove. A limiting rod 25 is fixedly installed on one side of the two fixing blocks 8 that are close to each other and at one end away from the socket. The limiting rod 25 passes through the socket and extends to the inside of the mounting groove, and the limiting structure 20 is located on the upper and lower sides of the limiting rod 25.

[0036] When one side of the two fixing blocks 8 fits together, the limiting rod 25 is inserted into the interior of the installation groove through the insertion hole, and the limiting rod 25 is limited by the limiting structure 20 at the same time, so that the two fixing blocks 8 are fixed, which makes it easier for the sealing ring 4 to be installed in the installation groove at the bottom end of the pressure interface 2, so as to improve stability.

[0037] like Figure 8 As shown, the limiting structure 20 includes a tooth plate 201, one side of the tooth plate 201 is meshed with a second gear 202, the middle of the second gear 202 is fixedly connected with a movable rod 203, both ends of the movable rod 203 are rotatably connected to the inner wall of the mounting groove, a fixed spring 204 is fixedly installed at the top of the tooth plate 201 and located on one side of the second gear 202, one end of the fixed spring 204 is installed with the inner wall of the mounting groove, the tooth plate 201 is in an inclined state, the side of the tooth plate 201 away from the second gear 202 is in contact with the side of the limiting rod 25, the tooth plate 201, the second gear 202, the limiting rod 25 and the fixed spring 204 are symmetrically arranged with the center of the limiting rod 25.

[0038] When the limiting rod 25 passes through the insertion hole and moves into the installation groove, the limiting rod 25 passes through two symmetrically arranged tooth plates 201, and one end of the limiting rod 25 squeezes the tooth plate 201, causing the tooth plate 201 to deflect, and the gear drives the movable rod 203 to rotate, and the fixed spring 204 is compressed. When the limiting rod 25 is completely moved into the installation groove, the tooth plate 201 is close to one end of the fixed spring 204 and fits with the upper and lower sides of the limiting rod 25, thereby supporting and fixing the upper and lower sides of the limiting rod 25, thereby improving the stability of the fitting and fixing of the two fixing blocks 8, thereby facilitating the installation of the sealing ring 4.

[0039] like Figure 3As shown, the adjustment structure includes a servo motor 26, a rotating shaft 27 is fixedly installed at the output end of the servo motor 26, a first rotating wheel 28 is fixedly installed at the bottom end of the rotating shaft 27, a second rotating wheel 29 is meshed with one side of the first rotating wheel 28, second magnetic blocks 30 are fixedly installed at both ends of the bottom of the second rotating wheel 29, the first magnetic block 21 is magnetically connected to the second magnetic block 30, the servo motor 26 is fixedly installed on the top inner wall of the mounting block 7, the first rotating wheel 28 is located on one side of the inside of the mounting block 7, the second rotating wheel 29 is located in the middle position inside the mounting block 7, the pressure interface 2 is located in the middle of the second rotating wheel 29, the second rotating wheel 29 is located at the moving port, a moving rod 31 is fixedly installed on the top of the second rotating wheel 29, and the bottom of the moving rod 31 is slidably connected to the top inner wall of the mounting block 7.

[0040] By starting the servo motor 26, the rotating shaft 27 and the first rotating wheel 28 are driven to rotate, so that the second rotating wheel 29 rotates, and the second rotating wheel 29 rotates inside the mounting block 7 through the moving rod 31. Through the magnetic connection between the first magnetic block 21 and the second magnetic block 30, the moving block 19 drives the connecting spring 18 and the limiting block 17 to move, so that the second rack 16 is separated from the first gear 15, so as to facilitate the limiting block 17 to rotate on the top of the sealing ring 4. At the same time, the rotation keeps the top of the sealing ring 4 flat without distortion, thereby improving the installation effect of the sealing ring 4 and preventing the grouting pressure sensor from leaking during use, thereby affecting its use.

[0041] Working principle: When in use, by installing the mounting plate 5 on one end of the sensor body 1 close to the pressure interface 2, the first connecting rod 6 drives the mounting block 7 and the adjustment structure inside it to be installed on the top of the pressure interface 2, the sensor body 1 passes through the middle of the mounting block 7, and then the sealing ring 4 is placed on the two clamping blocks 12 inside the fixing block 8, and then the two sides of the two fixing blocks 8 are fitted together, and the limiting rod 25 is inserted into the inside of the mounting groove through the jack. When the limiting rod 25 moves into the inside of the mounting groove, it squeezes the tooth plate 201, causing the tooth plate 201 to deflect, and the second gear 202 drives the movable rod 203 to rotate, and the fixed spring 204 presses When the limiting rod 25 is completely moved into the installation groove, the tooth plate 201 is close to one end of the fixing spring 204 and fits with the upper and lower sides of the limiting rod 25, thereby supporting and fixing the upper and lower sides of the limiting rod 25, so that the two fixing blocks 8 are fit and fixed, and the fixing block 8 is placed at the bottom of the installation block 7, and the fixing block 8 is installed at the bottom of the installation block 7 by plugging the plug rod 23 with the slot 22, and then the pressure interface 2 passes through the fixing block 8, and the baffle 24 is rotated to expose the movable port, and then the first electric push rod 9 is started to push the fixing plate 10 and the second electric push rod 11 to move downward, so that the block 12 drives the sealing ring 4 and the pressure interface 2 corresponds to the sealing groove 3 at the bottom. When the first electric push rod 9 moves downward, it drives the fixing rod 13 and the first rack 14 to move, so that the first gear 15 rotates, and the second rack 16 drives the limiting block 17 to move upward, so that the connecting spring 18 is compressed, so that the limiting block 17 is away from the sealing ring 4, and then the second electric push rod 11 is started to push the block 12 close to the sealing groove 3, so that the sealing ring 4 is close to the sealing groove 3. When the sealing ring 4 is close to the sealing groove 3, the first electric push rod 9 is started again to drive the fixing plate 10, the second electric push rod 11 and the block 12 to move downward, so that the block 12 is separated from the sealing ring 4, and the sealing The ring 4 is no longer restricted and shrinks toward the middle under the action of elasticity, so that the sealing ring 4 moves to the inside of the sealing groove 3. After the installation is completed, the second electric push rod 11 drives the block 12 to move to the original position, and the first electric push rod 9 drives the fixed plate 10 and the second electric push rod 11 and the block 12 to move upward to the inside of the fixed block 8. At the same time, through the action of the first rack 14, the first gear 15 and the second rack 16, the connecting spring 18 stretches and pushes the limiting block 17 to move downward to press and fix the sealing ring 4 inside the sealing groove 3, so that the sealing ring 4 and the pressure interface 2 remain sealed, which is convenient for the installation of the sealing ring 4.

[0042] When the sealing ring 4 is installed, the servo motor 26 is started to drive the rotating shaft 27 and the first rotating wheel 28 to rotate, so that the second rotating wheel 29 drives the moving rod 31 to rotate, and the second rotating wheel 29 rotates inside the mounting block 7 through the moving rod 31, and through the magnetic connection between the first magnetic block 21 and the second magnetic block 30, the moving block 19 drives the connecting spring 18 and the limiting block 17 to move, so that the second rack 16 is separated from the first gear 15, so as to facilitate the limiting block 17 to rotate on the top of the sealing ring 4, so that the top of the sealing ring 4 remains flat and will not be twisted, thereby improving the installation effect of the sealing ring 4 and preventing the grouting pressure sensor from leaking during use, thereby affecting its use.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
