Description

Technical Field

[0001] The utility model relates to the technical field of permeameter equipment, in particular to a permeameter. Background Technique

[0002] The coefficient of permeability is an important index reflecting the permeability of soil. The permeability test is an important method for measuring the coefficient of permeability of soil and an important part of geotechnical tests. At present, for fine-grained soil, the variable-head permeability test is usually adopted. Its principle is to install the formed soil sample in a permeation container and let it stand for a certain period of time under a certain head pressure, while recording the change of the water head. Although the principle of this test method is simple, the accuracy of its test results is not high during the test process.

[0003] For example, the patent document with the publication number CN 219224499 U discloses a permeameter, including a device main body. A placement groove is formed in the left outer wall of the device main body. An installation groove is fixedly assembled on the inner wall of the placement groove. A controller is fixedly assembled on the inner wall of the installation groove. A guide plate is fixedly assembled at the top of the inner wall of the placement groove. An air pump is fixedly assembled on the right outer wall of the device main body. A control panel is fixedly assembled on the front outer wall of the device main body. By wrapping the sealant around the outer edge of the concrete test block and through a connection component, the gas generated by the operation of the air pump is transmitted between the expansion piece and the mother seat shell, so that the expansion piece expands towards the sealant side, thereby increasing the fit degree of the sealant and the concrete test block. By using the expansion piece instead of the sealing ring, the problem that the sealing ring needs to be repeatedly installed and removed during the test, resulting in many working steps and low working efficiency, is solved.

[0004] However, when this structure is used for actual concrete test block permeability testing, it can often only perform the one-by-one loading and unloading detection operation of concrete test blocks, resulting in low efficiency of the device during the permeability test, unable to achieve continuous and efficient concrete test block permeability testing operations. At the same time, the device cannot perform more precise sealing concrete test block permeability testing operations and cannot meet the daily use requirements. Therefore, it is urgent to design a permeameter to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a permeameter to solve the problem that the existing structure can often only perform the one-by-one loading and unloading detection operation of concrete test blocks during actual concrete test block permeability testing, resulting in low efficiency of the device during the permeability test, unable to achieve continuous and efficient concrete test block permeability testing operations. At the same time, the device cannot perform more precise sealing concrete test block permeability testing operations and cannot meet the daily use requirements as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A permeameter, comprising a permeation frame, a liquid storage tank is fixedly connected to the back of the permeation frame, an infusion pump is arranged at the top of the liquid storage tank, a storage rack is fixedly connected to the top of the permeation frame, and a hydraulic rod is arranged at the top of the storage rack;

[0007] A conveying rack, a conveying rack is fixedly connected to the bottom of the permeation frame, a conveyor belt is arranged inside the conveying rack, and a detection rack is movably connected to the surface of the conveyor belt.

[0008] Preferably, a magnetic attraction strip is arranged on the surface of the conveyor belt, and a magnetic attraction plate is arranged at the bottom of the detection rack.

[0009] Preferably, a permeation tank is arranged at the center of the side of the detection rack, and a water receiving tank is arranged at the bottom of the permeation tank.

[0010] Preferably, a sealing frame is arranged at the top of the detection rack, and telescopic air bags are arranged at the top of both ends of the detection rack.

[0011] Preferably, a positioning rack is fixedly connected to the inner top wall of the permeation frame, and abutting arc grooves are arranged at both ends of the bottom of the positioning rack.

[0012] Preferably, a lifting rack is arranged inside the storage rack through a hydraulic rod, and a permeation pressure nozzle is arranged inside the lifting rack.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] For this permeameter, by setting the permeation frame, liquid storage tank, infusion pump, storage rack, hydraulic rod, conveying rack, conveyor belt, detection rack, magnetic attraction strip, magnetic attraction plate, permeation tank, water receiving tank, lifting rack and permeation pressure nozzle, the equipment can perform continuous and efficient concrete test block permeation tests. During actual use, the staff first puts the concrete test block to be subjected to permeation test into the permeation tank of the detection rack, performs waterproof treatment on the edge, and then fixes the whole detection rack to the magnetic attraction strip on the surface of the conveyor belt inside the conveying rack through the magnetic attraction plate at the bottom for positioning and adsorption. Then, the whole detection rack moves along with the conveyor belt into the permeation frame. The hydraulic rod on the surface of the storage rack can be started to drive the lifting rack and permeation pressure nozzle at one end to abut against the center of the top of the detection rack. At this time, the permeation water in the liquid storage tank is quickly pressurized and introduced into the permeation tank of the detection rack through the permeation pressure nozzle in cooperation with the infusion pump, and the water receiving tank performs permeation water receiving operation. The equipment can continuously perform rapid permeation detection operations on multiple groups of detection racks inside the permeation frame, so as to realize continuous detection of the concrete test block inside the permeation tank, ensure the accuracy of the experimental results, and reflect the practicability of the equipment design.

[0015] This permeameter further improves the overall usage effect of the equipment through the provided permeation rack, detection rack, permeation tank, water receiving tank, sealing frame, telescopic airbag, positioning rack, and top connection arc groove. During daily use, when the detection rack enters the interior of the permeation rack, the telescopic airbags at both ends of the top of the detection rack can be activated to inflate and press adaptively against the top connection arc grooves at both ends of the bottom of the hydraulic rod, thereby quickly positioning and locking the entire detection rack inside the permeation rack. Subsequently, the lifting rack and permeation pressure nozzle driven by the hydraulic rod can be adaptively pressed against the sealing frame at the center of the surface of the detection rack for top sealing and fitting operations, enabling the permeation pressure nozzle to perform sealed pressurization operations inside the permeation tank and the water receiving tank, improving the effect of concrete specimen permeation detection and reflecting the comprehensiveness of the equipment design.
