DETAILED DESCRIPTION

[0028] The specific implementation of the utility model will be further described in detail below with reference to the accompanying drawings.

[0029] A concrete strength detection device for water conservancy engineering in this specific implementation manner, such as Figure 1-5 As shown, it comprises a container mechanism 1, the interior of the container mechanism 1 contains liquid, a concrete fixing mechanism 2 is installed inside the container mechanism 1, and a water-displacing mechanism 3 is also installed inside the container mechanism 1, and the water-displacing mechanism 3 is used to stir water flow to impact concrete fixed on the concrete fixing mechanism 2;

[0030] The concrete fixing mechanism 2 comprises: an inclined support slope 201, a concrete clamping plate 202 is fixedly connected to the top of the inclined support slope 201, a bolt hole 203 is opened on the concrete clamping plate 202, and bolts are passed through the bolt holes 203 to fix and limit the concrete;

[0031] The water-diverting mechanism 3 includes a transmission device 301 installed on the outer surface of the container mechanism 1 and a synchronous belt 302 installed inside the container mechanism 1. A roller is arranged inside the synchronous belt 302 to support the synchronous belt 302, and the roller is driven by the transmission device 301. A water flow paddle 303 is arranged on the outer surface of the synchronous belt 302. The water flow paddle 303 pushes the water flow when the synchronous belt 302 moves.

[0032] Through the above technical solution, an inclined support slope 201 is arranged inside the container mechanism 1 to support the concrete block, and bolts are passed through the bolt holes 203 to fix the concrete from both sides of the concrete block. Then, the transmission device 301 drives the synchronous belt 302, so that the water flow paddle 303 pushes the water in the container mechanism 1 to quickly and continuously flush the concrete block, thereby testing the strength of the concrete block against water impact and the ability of water erosion.

[0033] By changing the rotation speed of the transmission device 301, the water flow paddle 303 can achieve the purpose of high movement and slow movement. The highly moving water flow paddle 303 can increase the impact force of the water flow to test the strength of the concrete block to resist the impact of the water flow. The slowly moving water flow paddle 303 is used to gently push the water flow, thereby testing the strength of the concrete to resist water flow erosion under slow flow. If used in a seaside environment, salt can be added to the water in the container mechanism 1 to simulate the erosion of seawater.

[0034] Specifically, the inclined support slope 201 is an inclined slope, the concrete clamping plate 202 is L-shaped, and the bottom of the concrete clamping plate 202 is welded to the top of the inclined support slope 201 .

[0035] Through the above technical solution, the inclined support slope 201 is set as an inclined slope, so that when the concrete block is fixed, the concrete block is also set at an angle, so that the contact area between the concrete block and the water flow can be increased, so as to increase the detection area of ​​the concrete block;

[0036] The shape of the concrete clamping plate 202 is set to increase the contact area between the concrete clamping plate 202 and the inclined support slope 201 and to increase the strength of the concrete clamping plate 202 .

[0037] Specifically, there are multiple bolt holes 203 , and the multiple bolt holes 203 are linearly and equidistantly distributed.

[0038] Through the above technical solution, the purpose of setting multiple bolt holes 203 is to increase the position where the bolts can be fixed, so that concrete blocks of different sizes can be fixed using bolts. In order to adapt to concrete blocks of different sizes, the length of the bolts passing through the bolt holes 203 is also adapted to the size of the concrete blocks.

[0039] Specifically, the water flow paddle 303 is an arc-shaped plate structure, and the water flow paddle 303 and the synchronous belt 302 have the same width.

[0040] Through the above technical solution, the water flow paddle 303 is set to an arc-shaped plate structure, so that the ability of the water flow paddle 303 to push the water flow can be improved, thereby increasing the impact force of the water flow on the concrete block.

[0041] Specifically, the water flow paddles 303 are fixed on the outer surface of the synchronous belt 302 in an equidistant and circular manner, and the bottom of the water flow paddles 303 is close to the inner bottom of the container mechanism 1 .

[0042] Through the above technical solution, a large number of water flow paddles 303 are set to continuously push the water flow to increase the impact frequency of the water flow, thereby achieving the purpose of rapid detection. If the impact frequency of the water flow paddles 303 is small, the process of water impact resistance detection of the concrete block will be relatively long.

[0043] Specifically, the top of the container mechanism 1 is fixedly connected with a protection mechanism 4, and the protection mechanism 4 covers the top of the container mechanism 1 to prevent water splashing.

[0044] Through the above technical solution, the purpose of setting the protection mechanism 4 is to cover the top of the container mechanism 1, so as to effectively prevent the water flow from rushing out of the equipment, so as to save water resources and prevent the external ground from being polluted by the water flow.

[0045] Specifically, the protection mechanism 4 includes a fixed protection cover 401 . The fixed protection cover 401 covers the top of the synchronous belt 302 , and the length of the fixed protection cover 401 is half of the length of the container mechanism 1 .

[0046] Through the above technical solution, a fixed protective cover 401 is set to cover the top of the synchronous belt 302, so as to prevent water from being thrown out of the device during the movement of the water flow paddle 303, because when the water flow paddle 303 rotates, it will drive the water to move to the right side of the device, thereby splashing out from the right side of the device.

[0047] Specifically, the top of the container mechanism 1 is fixedly connected with a slide rail 101, and the protection mechanism 4 also includes a movable protection cover 402, which is symmetrical to the fixed protection cover 401, and a slider is installed at the bottom of the movable protection cover 402, which is slidably connected with the slide rail 101.

[0048] Through the above technical solution, the purpose of setting the slide rail 101 is to connect and support the movable protective cover 402, so that the movable protective cover 402 can slide left and right. When the movable protective cover 402 slides to the left, a gap can be left between the fixed protective cover 401 and the movable protective cover 402 to facilitate the placement of concrete blocks. When the movable protective cover 402 moves to the right, the fixed protective cover 401 and the movable protective cover 402 can fit each other, thereby achieving complete sealing of the top of the container mechanism 1 to completely avoid splashing water.

[0049] In order to better observe the status of the concrete block, the main bodies of the fixed protective cover 401 and the movable protective cover 402 may be transparent.

[0050] When in use, the concrete block is supported by setting an inclined support slope 201 inside the container mechanism 1, and bolts are passed through the bolt holes 203 to fix the concrete from both sides of the concrete block. Then, the transmission device 301 drives the synchronous belt 302, so that the water flow paddle 303 pushes the water in the container mechanism 1 to quickly and continuously flush the concrete block, thereby testing the strength of the concrete block against water impact and the ability of water erosion;

[0051] By installing a fixed protective cover 401 above the container mechanism 1 to cover the top of the synchronous belt 302, water can be prevented from being thrown out of the equipment during the movement of the water flow paddle 303, and a movable protective cover 402 is set to cover the top of the inclined support slope 201, so as to effectively prevent water from splashing when it hits the outer surface of the concrete block, thereby achieving a splash-proof effect.

[0052] It should be noted that although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
