Description

Technical Field

[0001] The present application relates to the field of water injection devices, and in particular to a water injection device for research and development experiments of early-strength concrete admixtures. Background Art

[0002] Concrete admixtures are substances added to improve and adjust the properties of concrete. Their application in engineering projects is gaining increasing attention. While the addition of admixtures plays a role in improving concrete's performance, their development is significantly impacted by the selection, addition method, and adaptability of the admixture. Laboratory research and development of concrete admixtures requires performance testing, which requires the use of water injection devices.

[0003] Before existing concrete admixtures are put into use, they need to undergo compressive strength tests, flexural strength tests, plastic viscosity tests, and curing time tests. During the experiments, water needs to be added to the inside of the test frame to mix the concrete admixture and concrete, so as to observe the changes in the concrete after the addition of the concrete admixture.

[0004] During the existing concrete admixture experiment, when injecting water, personnel need to observe the water dosage next to the experimental frame and prepare to shut down the water supply equipment. During the observation process, the staff's time is delayed and the work progress is slowed down. Utility Model Content

[0005] The purpose of this application is to solve the problem in the above background technology that workers need to observe the water injection volume of the experimental frame, which wastes the workers' time. This application provides a water injection device for early-strength concrete admixture research and development experiments.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A water injection device for early-strength concrete admixture research and development experiments, comprising an experimental frame, a mounting plate fixedly mounted on one side of the surface of the experimental frame, a water pump fixedly mounted on the surface of the mounting plate, a drain pipe fixedly mounted on the output end of the water pump, a threaded groove provided on the surface of the drain pipe, a guide tube passing through the internal thread of the threaded groove, a control component provided inside the guide tube, a trigger switch fixedly mounted on one side inside the experimental frame, a mounting groove provided on a side adjacent to the bottom of the trigger switch, an automatic quantitative structure embedded inside the mounting groove.

[0008] During use, the water pump is connected to the power supply, and its output end guides water into the experimental frame through the guide tube on the drain pipe. The personnel can control the speed of water injection by adjusting the control component. When water is injected into the interior of the experimental frame, the water will move the floating ball in the automatic quantitative structure. When the floating ball floats to a certain horizontal plane, it will press the trigger switch to turn off the water pump, thereby achieving the effect of automatic quantitative injection.

[0009] Furthermore, the automatic quantitative structure includes a constraint plate fixedly installed inside the mounting groove, an observation tube fixedly installed on the surface of the constraint plate through an adjustment component, a floating ball is provided inside the observation tube, and a telescopic rod is fixedly connected to the surface of the floating ball.

[0010] By adopting the above technical solution and utilizing the setting of the automatic quantitative structure, the water injection volume can be automatically quantified, which reduces the tedious operations of personnel and improves work efficiency.

[0011] Furthermore, the adjustment assembly includes support plates fixedly mounted on both sides of the surface of the constraint plate, a through groove is opened on the surface of the support plate, a threaded rod is passed through the inside of the through groove, moving blocks are threadedly connected on both sides of the surface of the threaded rod, and an arc plate is fixedly mounted on the surface of the moving block.

[0012] By adopting the above technical solution and utilizing the setting of the regulating component, the quantitative amount of water injection can be controlled, thereby improving the practicality of the water injection device and making it more adaptable.

[0013] Furthermore, the telescopic rod includes a sleeve fixedly mounted on the surface of the floating ball, and the internal thread of the sleeve is threadedly connected to the lifting rod.

[0014] By adopting the above technical solution and setting the telescopic rod, the telescopic rod can be adjusted synchronously according to the adjustment of the adjustment component, thereby reducing the occurrence of the situation where the trigger switch cannot be touched due to insufficient length of the telescopic rod.

[0015] Furthermore, the bottom of the observation tube is clamped to a limit ring via a clamping rod, and the diameter of the groove provided on the surface of the limit ring is smaller than the diameter of the floating ball.

[0016] By adopting the above technical solution, the floating ball inside the observation tube can be disassembled and cleaned through the setting of the clamping rod and the limit ring. If the floating ball is in water for a long time, plants are easily grown on the surface of the floating ball, resulting in inaccurate control of the water injection volume.

[0017] Furthermore, the control component includes an adjustment ring rotatably connected to one end of the guide tube, a sliding groove is provided on the surface of the adjustment ring, a sliding plate is slidably connected inside the sliding groove, a control rod is fixedly installed on the surface of the sliding plate, and the surface of the control rod is sleeved with the guide ring.

[0018] By adopting the above technical solution and utilizing the setting of the control component, the water injection speed can be controlled during water injection, thereby reducing the occurrence of excessive water flow rate, which leads to waste of water resources.

[0019] Furthermore, the surface of the guide ring is provided with arc grooves in a ring array, and the size of the arc grooves is adapted to the size of the control rod.

[0020] By adopting the above technical solution and utilizing the arrangement of the arc groove, the sliding plate can be controlled by the control rod so as to slide toward the two side pieces, thereby improving the stability of the sliding plate during movement.

[0021] Furthermore, limiting grooves are provided on both sides of the surface of the guide tube, and the size of the limiting grooves is adapted to the size of the sliding plate.

[0022] By adopting the above technical solution and setting the limiting groove, the sliding plate can slide on both sides, while reducing the occurrence of insufficient sliding space for the sliding plate.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In this application, through the setting of a trigger switch, a water pump and an automatic quantitative structure, during use, the personnel adjusts the automatic quantitative structure to an appropriate height through the adjustment component and adjusts the dosage of water required. After adjustment, the personnel uses the water pump to pump water into the interior of the experimental frame. When a certain dosage is pumped, the floating ball in the automatic quantitative structure will move upward, and the trigger switch is directly above the floating ball. The floating ball drives the telescopic rod to press the trigger switch to turn off the water pump, thereby playing the role of automatic quantitative filling when water is injected.

[0025] 2. In this application, through the setting of the guide tube and the control component, during use, the water pumped out by the water pump will enter the experimental frame through the guide tube, and then the personnel can rotate the adjustment ring through the guide tube. During the rotation, it will drive the sliding plate to slide inside the slide groove, and the control rod on the sliding plate will move through the arc groove track on the guide ring, and the sliding plate will move to both sides accordingly. The personnel can adjust the water injection speed by rotating the adjustment ring to adjust the water injection speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiments of the present application disclose a water injection device for use in research and development experiments of early-strength concrete admixtures.

[0034] Reference Figure 1 and Figure 2 A water injection device for the research and development experiment of early-strength concrete admixture includes an experimental frame 1, a mounting plate 2 is fixedly installed on one side of the surface of the experimental frame 1, a water pump 3 is fixedly installed on the surface of the mounting plate 2, a drainage pipe 4 is fixedly installed on the output end of the water pump 3, a threaded groove is provided on the surface of the drainage pipe 4, a guide tube 5 is passed through the internal thread of the threaded groove, a control component 6 is provided inside the guide tube 5, a trigger switch 7 is fixedly installed on one side of the interior of the experimental frame 1, a mounting groove is provided on the side adjacent to the bottom of the trigger switch 7, and an automatic quantitative structure 8 is embedded in the interior of the mounting groove.

[0035] During use, the water pump 3 is connected to the power supply, and its output end guides water into the experimental frame 1 through the guide tube 5 on the drain pipe 4. The personnel can control the water injection speed by adjusting the control component 6. When water is injected into the interior of the experimental frame 1, the water will move the floating ball 804 in the automatic quantitative structure 8. When the floating ball 804 floats to a certain horizontal plane, it will press the trigger switch 7 to turn off the water pump 3, thereby playing the role of automatic quantitative measurement.

[0036] Reference Figure 2 and Figure 3The automatic quantitative structure 8 includes a constraint plate 801 fixedly installed inside the mounting groove, and an observation tube 803 is fixedly installed on the surface of the constraint plate 801 through an adjustment component 802. A floating ball 804 is provided inside the observation tube 803, and a telescopic rod 805 is fixedly connected to the surface of the floating ball 804.

[0037] Among them, the adjustment component 802 includes a support plate 8021 fixedly installed on both sides of the surface of the constraint plate 801, a through groove is opened on the surface of the support plate 8021, a threaded rod 8022 is passed through the inside of the through groove, and a moving block 8023 is threadedly connected on both sides of the surface of the threaded rod 8022, and an arc plate 8024 is fixedly installed on the surface of the moving block 8023.

[0038] Furthermore, the telescopic rod 805 includes a sleeve 8051 fixedly mounted on the surface of the floating ball 804 , and the internal thread of the sleeve 8051 is threadedly connected to the lifting rod 8052 .

[0039] In addition, the bottom of the observation tube 803 is clamped to the limit ring 10 through the clamping rod 9, and the diameter of the groove provided on the surface of the limit ring 10 is smaller than the diameter of the floating ball 804.

[0040] During use, in case 1, the personnel rotates the threaded rod 8022 through the support plate 8021, and the moving block 8203 on the threaded rod 8022 will move accordingly, and move through the curved plate 8024 during the movement, and the curved plate 8024 will drive the observation tube 803 to move accordingly, and at the same time rotate the lifting rod 8052 through the sleeve 8051, and adjust the lifting rod 8052 to different heights to match the height of the observation tube 803. The adjustment at this time is when the required water injection volume is low, and the horizontal plane of the required water injection volume is lower than the bottom of the observation tube 803, which requires adjusting the height of the observation tube 803. In the second case, when the required water level is between the top and bottom of the observation tube 803, only the length of the telescopic rod 805 needs to be adjusted. When the observation tube 803 moves, the internal floating ball 804 will drive the telescopic rod 805 to move accordingly. After water enters the observation tube 803, the water will drive the floating ball 804 to rise with the water level. When it rises to a certain position, the floating ball 804 will drive the telescopic rod 805 to press the trigger switch 7, turning off the water pump 3, achieving the function of automatically determining the water injection amount and improving the work efficiency of the personnel. At the same time, the personnel can remove the internal floating ball 804 by removing the limit ring 10 through the clamping rod 9 for removal and cleaning.

[0041] Reference Figure 2 and Figure 4The control component 6 includes an adjusting ring 601 rotatably connected to one end of the guide tube 5. A sliding groove is provided on the surface of the adjusting ring 601. A sliding plate 602 is slidably connected inside the sliding groove. A control rod 603 is fixedly installed on the surface of the sliding plate 602. A guide ring 604 is sleeved on the surface of the control rod 603.

[0042] The surface of the guide ring 604 is provided with arc grooves in a circular array, and the size of the arc grooves is adapted to the size of the control rod 603 .

[0043] In addition, limiting grooves are provided on both sides of the surface of the guide tube 5 , and the size of the limiting grooves is adapted to the size of the sliding plate 602 .

[0044] During the water injection process, when the water flow rate is too fast, the adjusting ring 601 will be rotated through the guide tube 5, and the sliding plate 602 will move along the trajectory of the arc groove provided on the surface of the guide ring 604 through the control rod 603 as the adjusting ring 601 rotates, and the sliding plate 602 will slide on both sides accordingly. When sliding, the water will flow out through the gap between the sliding plates 602, which plays a role in controlling the water flow rate during the water injection process and reducing the waste of water resources.

[0045] Working principle: The threaded rod 8022 is rotated through the support plate 8021, and the moving block 8203 on the threaded rod 8022 will move accordingly. During the movement, the curved plate 8024 moves, and the curved plate 8024 will drive the observation tube 803 to move. At the same time, the lifting rod 8052 is rotated through the sleeve 8051. The lifting rod 8052 is adjusted to different heights to match the height of the observation tube 803, thereby adjusting different automatic quantitative dosages.

[0046] Then the water pump 3 is turned on, and water flows into the guide pipe 5 through the drain pipe 4. The operator rotates the adjustment ring 601 through the guide pipe 5. Then the sliding plate 602 follows the trajectory of the arc groove on the surface of the guide ring 604 through the control rod 603 as the adjustment ring 601 rotates. The sliding plates 602 slide on both sides accordingly. When sliding, water flows out through the gap between the sliding plates 602, which controls the flow rate of water during the water filling process.

[0047] When the adjustment component 802 drives the observation tube 803 to move, the internal floating ball 804 will also drive the telescopic rod 805 to move. After the water enters the observation tube 803, the water will drive the floating ball 804 to rise along the horizontal plane. When it rises to a fixed position, the floating ball 804 will drive the telescopic rod 805 to press the trigger switch 7, turn off the water pump 3, and automatically quantify the water injection amount.
