[0023] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As Figure 1 shown, an embodiment of the present utility model provides a substrate structure of a sand replacement method measuring instrument for installing a measuring instrument body 6, including: Figure 3 A substrate body 1, provided with a through hole 101 corresponding to the measuring instrument body 6;

[0025] Two mounting brackets 3, the substrate body 1 is provided with a mounting groove 103, and the two mounting brackets 3 are slidably arranged in the mounting groove 103 in a mirror image manner; and

[0026] A mounting unit, including a fastener arranged in the mounting groove 103 and a clamping block 5 arranged on the mounting bracket 3, the fastener is connected to the two mounting brackets 3 and is used to make the two clamping blocks 5 approach or move away from each other, so as to fix the substrate body 1 to the ground or release the restriction on it.

[0027] In an embodiment of the present utility model, when performing sand replacement method measurement for installing the substrate body 1, the substrate body 1 is directly placed on the surface to be measured, so that the through hole 101 of the substrate body 1 is aligned with the surface to be measured or the pit position. Then, the two mounting brackets 3 in the mounting groove 103 are respectively pulled out, so that the two mounting brackets 3 move out to both sides of the substrate body 1 respectively, which can increase the contact area between the substrate body 1 and the ground, thereby ensuring a certain stability. Among them, the ground needs to be ensured to be flat. Then, two holes corresponding to both sides of the substrate body 1 are opened on the ground, and the clamping blocks 5 on the two mounting brackets 3 are respectively clamped into the holes, so that the clamping blocks 5 are placed underground. By adjusting the fastener, the fastener drives the two mounting brackets 3 to move into the mounting groove 103, thereby reducing the distance between the two clamping blocks 5, so that the two clamping blocks 5 respectively abut against the side walls of the corresponding holes, realizing the clamping installation of the substrate body 1, ensuring the stability of the substrate body 1 on the surface to be measured. During the measurement process, manual assistance for pressing is not required, saving manpower and ensuring the accuracy of the measurement result. After subsequent use, by adjusting the fastener again, the two clamping blocks 5 move away from each other, so as to separate from the side walls of the holes, and the substrate body 1 can be directly removed, realizing rapid disassembly.

[0028] Based on the above solution, as

[0029] shown, the fastener is a bidirectional screw rod 4, two mounting blocks 104 are fixedly arranged in the mounting groove 103, the bidirectional screw rod 4 is rotatably arranged between the two mounting blocks 104, and both ends of the bidirectional screw rod 4 are respectively threadedly connected to the two mounting brackets 3. Figure 2

[0030] ​Specifically, when adjusting the two mounting brackets 3 by setting fasteners, internal threads are provided at the ends of the mounting brackets 3, and the internal threads are engaged with the threaded portions of the bidirectional screw 4. The thread directions of the bidirectional screw 4 are opposite. When the bidirectional screw 4 is rotated, the two mounting brackets 3 approach or move away from each other at both ends of the bidirectional screw 4, thereby realizing the adjustment of the two clamping blocks 5.

[0031] Moreover, as Figure 2 shown, a first bevel gear 401 and a second bevel gear 402 that mesh with each other are provided between the two mounting blocks 104. The first bevel gear 401 is fixedly provided on the bidirectional screw 4, the second bevel gear 402 is rotatably provided in the mounting groove 103, and the substrate body 1 is provided with a knob 403. The knob 403 penetrates into the mounting groove 103 and is connected to the second bevel gear 402. In order to more conveniently adjust the bidirectional screw 4, directly rotate the knob 403 on the substrate body 1, so that the knob 403 drives the connected second bevel gear 402 to rotate. When the second bevel gear 402 and the first bevel gear 401 are engaged, the second bevel gear 402 drives the first bevel gear 401 to rotate, so that the first bevel gear 401 drives the bidirectional screw 4 to rotate. The forward and reverse rotation of the bidirectional screw 4 can be directly controlled by the forward and reverse rotation of the knob 403, and the operation is more convenient.

[0032] Based on the above solution, as Figure 1 and Figure 4 shown, the mounting bracket 3 is provided with a groove. The clamping block 5 includes a telescopic cylinder 502 provided in the groove and a telescopic block 501 slidably provided in the telescopic cylinder 502. A spring 504 is provided in the telescopic cylinder 502, and the spring 504 abuts against the top end of the telescopic block 501. The clamping block 5 is composed of the telescopic cylinder 502 and the telescopic block 501, so that the clamping block 5 forms a telescopic structure. When the mounting bracket 3 is stored, by pressing the telescopic cylinder 502, the overall length of the telescopic cylinder 502 and the telescopic block 501 is the same as that of the groove, so that the mounting bracket 3 can be completely stored in the mounting groove 103, which is convenient for storage. When the mounting bracket 3 is taken out, the restriction of the mounting groove 103 on the telescopic block 501 is released, so that the telescopic block 501 can pop out under the action of the spring 504 for convenient fixed use.

[0033] Specifically, Figure 4 shown, a fixed tooth 503 is provided on one side of the telescopic block 501 close to the through hole 101. When the clamping block 5 abuts against the side of the ground hole under the action of the bidirectional screw 4, the fixed tooth 503 of the telescopic block 501 penetrates through the side of the hole, increasing the adhesion between the clamping block 5 and the side of the hole, thereby ensuring the stability of the fixed installation of the substrate body 1.

[0034] Specifically, as Figure 1As shown, a collection groove 102 is formed by downward depression of the substrate body 1; after measurement, the sand on the substrate body 1 that has not contacted the ground needs to be recycled. It is directly swept onto the substrate body 1 and stays in the collection groove 102, and can be used again after subsequent drying and sieving.

[0035] Specifically, as Figure 1 shown, a positioning ring 2 coaxial with the through hole 101 is provided in the collection groove 102, and the inner diameter of the positioning ring 2 is the same as the outer diameter of the measuring instrument body 6; under the action of the positioning ring 2, when installing the measuring instrument body 6, it is directly inserted into the positioning ring 2, so that the inner diameter of the measuring instrument body 6 always corresponds to the through hole 101 without deviation, ensuring the accuracy of the measurement result. Moreover, the inner side of the mouth of the positioning ring 2 has an inclined surface, which can guide the bottom of the measuring instrument body 6 into the positioning ring 2, further facilitating the installation and use.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
