Description

Technical Field

[0001] This invention relates to the field of concrete testing technology, specifically to a waterproof testing device for concrete test blocks. Background Technology

[0002] Concrete must have a certain degree of waterproofing performance according to relevant usage requirements; therefore, it is necessary to test the waterproofing performance of concrete.

[0003] CN220961129U discloses a concrete waterproofing performance testing device for building construction. By setting up a fixing mechanism, the concrete block can be fixed to prevent it from falling during testing. The water pressure from the nozzle can be adjusted by regulating the power of the water pump. Testing the concrete waterproofing performance using water droplets of different pressures improves the testing effect. Furthermore, the angle of the placement plate can be adjusted by the motor, enabling multi-faceted testing of the concrete block and further improving the testing effect and accuracy. However, this patent still has the following problems in practical use:

[0004] Although this concrete waterproofing performance testing device for building construction can adjust the pressure of the water droplets sprayed from the nozzle by adjusting the power of the water pump, and test the waterproofing performance of concrete by using water droplets with different pressures, the water pumped by the water pump is the return water after the concrete has been tested. Therefore, the return water is prone to impurities, which can easily damage the nozzle when it passes through it, thus reducing the practicality of the device.

[0005] A waterproof testing device for concrete test blocks is proposed to address the problems mentioned above. Summary of the Invention

[0006] The present invention provides the following technical solution: a waterproof testing device for concrete test blocks, including a screening mechanism and a high-pressure water pump installed inside the screening mechanism;

[0007] A clamping mechanism is provided on one side of the screening mechanism, and the bottom of the clamping mechanism is fixedly connected to the inner wall of the detection chamber.

[0008] Also includes:

[0009] The screening mechanism includes a testing chamber, a water storage tank is attached to the bottom of the testing chamber, a water outlet pipe is fixedly connected to one side of the top of the water storage tank, and one end of the water outlet pipe passes through the testing chamber and is fixedly connected to a filter box.

[0010] The bottom of the filter box is fitted and connected to the testing chamber. A filter frame is snapped into the inside of the filter box. Several filter screens are snapped into the inside of the filter frame. There are three filter screens, and the filter screens are evenly distributed inside the filter frame.

[0015] Preferably, the clamping mechanism includes a support frame, the bottom of which is fixedly connected to the testing chamber, a barrier is fixedly connected to the top of the support frame, a screen is fixedly connected to the center of the bottom of the barrier, a hopper is provided below the screen, one end of the hopper is fixedly connected to the support frame, and the other end of the hopper passes through the testing chamber and is fixedly connected to a water storage tank.

[0016] Preferably, a support column is fixedly connected to one side inside the enclosure, and sleeves are symmetrically fixedly connected to the top of the support column.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By setting up a screening mechanism, not only can the return water be filtered to improve water quality, but the filter screen can also be easily replaced. Water in the storage tank is pumped into the filter box by a high-pressure water pump. The return water is filtered through three layers of filter screens to remove larger impurities. Then, the return water passes through the high-pressure water pump and hose and is sprayed out from the high-pressure nozzle to perform waterproof testing on the concrete block. By pressing the button, the button moves within the limit sleeve. By using the cooperation between the button and the Z-shaped block, the stop bar can be moved into the limit sleeve, which can release the stop bar from limiting the filter box. The cover can then be opened to facilitate the removal of the filter frame inside the filter box for replacement or cleaning of the filter screen.

[0020] 2. By setting up a clamping mechanism, concrete blocks of different sizes can be quickly clamped, preventing the concrete blocks from shifting during the testing process and affecting the test results. The threaded action between the threaded rod and the sleeve can be used to change the length of the threaded rod extension. By using the connecting rod to limit the moving block, the moving block can be driven to move within the clamping block. At the same time, the clamping block rotates around the threaded rod, thus clamping concrete blocks of different sizes. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1

[0030] Please see Figure 1-7 The present invention provides a technical solution: a waterproof testing device for concrete test blocks, including a screening mechanism 1 and a high-pressure water pump 113 installed inside the screening mechanism 1; a clamping mechanism 2 is provided on one side of the screening mechanism 1, and the bottom of the clamping mechanism 2 is fixedly connected to the inner wall of the testing chamber 101; the screening mechanism 1 includes a testing chamber 101, a water storage tank 102 is attached to the bottom of the testing chamber 101, a water outlet pipe 103 is fixedly connected to one side of the top of the water storage tank 102, one end of the water outlet pipe 103 passes through the testing chamber 101 and is fixedly connected to a filter box 104, and the water storage tank 102 facilitates the reuse of water resources;

[0031] The bottom of the filter box 104 is fitted and connected to the test chamber 101. A filter frame 105 is snapped into the inside of the filter box 104. Several filter screens 106 are snapped into the inside of the filter frame 105. There are three filter screens 106, and the filter screens 106 are evenly distributed inside the filter frame 105. The filter screens 106 are set to facilitate the removal of impurities from the return water.

[0032] A cover plate 107 is attached to the top of the filter frame 105. One end of the cover plate 107 is rotatably connected to the filter box 104. A limit sleeve 108 is fixedly connected inside the other end of the cover plate 107. A button 109 is slidably connected inside the limit sleeve 108. A spring 110 is fixedly connected to one side inside the button 109. A stop bar 111 is fixedly connected to one end of the spring 110. By setting the spring 110, the stop bar 111 can always be engaged with the filter box 104 under normal conditions.

[0033] The end of the stop lever 111 away from the spring 110 passes through the limiting sleeve 108 and is fitted and connected to the filter box 104. A Z-shaped block 112 is slidably connected inside one end of the stop lever 111. Both ends of the Z-shaped block 112 are fitted and connected to the button 109. By using the cooperation between the button 109 and the Z-shaped block 112, the stop lever 111 can be moved into the limiting sleeve 108, which can release the limit of the stop lever 111 on the filter box 104.

[0034] The side of the filter box 104 away from the outlet pipe 103 is fixedly connected to the high-pressure water pump 113. The bottom of the high-pressure water pump 113 is fixedly connected to the test chamber 101. The output end of the high-pressure water pump 113 is fixedly connected to the hose 114. One end of the hose 114 is fixedly connected to the high-pressure nozzle 115. The top of the high-pressure nozzle 115 is fixedly connected to the test chamber 101. When the high-pressure water pump 113 is started, the water in the water storage tank 102 is pumped into the filter box 104. The return water is filtered through the three-layer filter screen 106, which can remove larger impurities in the water. Then the return water passes through the high-pressure water pump 113 and the hose 114 and is sprayed out from the high-pressure nozzle 115, so that the concrete block 210 can be tested for waterproofing.

[0035] The clamping mechanism 2 includes a bracket 201. The bottom of the bracket 201 is fixedly connected to the detection chamber 101. A barrier 202 is fixedly connected to the top of the bracket 201. A screen 203 is fixedly connected to the center of the bottom of the barrier 202. A hopper 204 is provided below the screen 203. One end of the hopper 204 is fixedly connected to the bracket 201. The other end of the hopper 204 passes through the detection chamber 101 and is fixedly connected to the water storage tank 102. The barrier 202 is used to prevent water from splashing everywhere.

[0036] A support column 205 is fixedly connected to one side inside the enclosure 202. A sleeve 206 is symmetrically fixedly connected to the top of the support column 205. A threaded rod 207 is threadedly connected to one end of the two sleeves 206. One end of the threaded rod 207 passes through the sleeve 206 and is symmetrically rotatably connected to a clamping block 208. A turntable is provided at the connection between the threaded rod 207 and the clamping block 208. The threaded rod 207 is rotatably connected to the turntable, and the turntable is rotatably connected to the clamping block 208.

[0037] Rubber blocks 209 are fixedly connected to the inner sides of the two clamping blocks 208. A concrete block 210 is attached to one side of the rubber block 209. A movable block 211 is slidably connected inside the clamping block 208. A connecting rod 212 is rotatably connected to one end of the movable block 211. A fixed block 213 is rotatably connected to the end of the connecting rod 212 away from the movable block 211. One end of the fixed block 213 is fixedly connected to the sleeve 206. By using the connecting rod 212 to limit the movable block 211, the movable block 211 can be moved within the clamping block 208.

[0038] Working principle: Before using this type of waterproof testing equipment for concrete test blocks, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 7 As shown, firstly, the concrete block 210 is placed between the two clamping blocks 208. Then, the threaded rod 207 is rotated. Using the thread action between the threaded rod 207 and the sleeve 206, the threaded rod 207 can be retracted into the sleeve 206. Using the connecting rod 212 to limit the movement block 211, the movement block 211 can be moved within the clamping block 208. At the same time, the clamping block 208 rotates around the threaded rod 207, so that concrete blocks 210 of different sizes can be clamped.

[0039] Next, the high-pressure water pump 113 is started to pump the water in the water storage tank 102 into the filter box 104. The return water is filtered through the three-layer filter screen 106 to remove larger impurities in the water. Then the return water passes through the high-pressure water pump 113 and the hose 114 and is sprayed out from the high-pressure nozzle 115 to perform waterproof testing on the concrete block 210.

[0040] Finally, pressing button 109 moves button 109 within the limiting sleeve 108. By utilizing the cooperation between button 109 and Z-shaped block 112, the stop bar 111 can be moved into the limiting sleeve 108, thereby releasing the stop bar 111 from limiting the filter box 104. This allows the cover plate 107 to be opened, making it easy to remove the filter frame 105 inside the filter box 104, so that the filter screen 106 can be replaced or cleaned.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
