These models are designed based on the hydraulic similarity principle and can simulate the dynamic changes of water flow and the diffusion process of substances in water in the natural environment in the laboratory. The research contents include flow velocity and flow state, water level and water surface line, discharge capacity, time-averaged pressure and pulsating pressure, local scouring and silting of riverbed, waves, water cavitation noise, water aeration concentration, ventilation wind speed and ventilation volume, rapids vibration and flood discharge atomization. When using the model to experiment with discharge capacity, a steep slope supported by an acrylic plate will be fixed on the discharge port of the reservoir model. When the reservoir discharges, the water flows directly out of the slope on the acrylic plate from the discharge port, and then the water pressure on the steep slope is detected by a pressure measuring tube, and then the liquid level in the liquid level tube beside the reservoir is visually displayed.

[0003] When using a pressure gauge to detect the pressure on the steep slope composed of acrylic plates, one end of the pressure gauge is directly against the back of the steep slope, and then the pressure probe on the pressure gauge is directly passed through the acrylic plate for fixation.

[0016] By adopting the above technical solution, when the fixed block two moves toward the fixed block one, the fixed block two drives the limit plate, the limit plate resists the synchronous moving component, and then the synchronous moving component simultaneously drives the two support rods to move toward the direction of the pressure measuring tube, and then the arc-shaped clamping blocks on the two support rods are clamped on the pressure measuring tube, thereby further improving the stability of the pressure measuring tube fixed on the discharge steep slope model and reducing the possibility of separation between the pressure measuring tube and the discharge steep slope model.

[0019] Furthermore, a support spring is provided between the second connecting rod and the first fixed block, and both ends of the support spring are fixedly connected to the second connecting rod and the first fixed block.

[0026] The following is combined with Figure 1 —5 further describes this application in detail.

[0027] The embodiment of the present application discloses a slope pressure test device for a reservoir discharge steep slope.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A slope pressure experimental device for a reservoir discharge steep slope comprises a corner 1 of a reservoir model, a discharge port is opened on the corner 1 of the reservoir model, a discharge steep slope model 2 is fixed on the corner 1 of the reservoir model, the discharge steep slope model 2 corresponds to the discharge port, a plurality of pressure measuring tubes 3 are fixed at the bottom of the discharge steep slope model 2, a plurality of connecting tubes 4 are fixed on the corner 1 of the reservoir model, the pressure measuring tubes 3 are correspondingly connected with the connecting tubes 4, liquid is poured into the connecting tubes 4, a reinforcement fixing mechanism 5 is arranged between the pressure measuring tube 3 and the discharge steep slope model 2, and an auxiliary stabilizing mechanism 6 is arranged between the pressure measuring tube 3 and the discharge steep slope model 2.

[0029] When conducting a slope pressure experiment on a reservoir discharge steep slope, first fix the pressure measuring tube 3 at the bottom of the discharge steep slope model 2, and then use the reinforcement fixing mechanism 5 to reinforce and fix the pressure measuring tube 3 to the discharge steep slope model 2. When using the reinforcement fixing mechanism 5 to reinforce and fix the pressure measuring tube 3, the auxiliary stabilizing mechanism 6 further fixes the pressure measuring tube 3 so that one end of the pressure measuring tube 3 is tightly against the discharge steep slope model 2. Then fill the reservoir model with water, and then let the water in the reservoir model flow out from the discharge port at one corner 1 of the reservoir model. When the water flows out from the discharge port, the water flows away from the discharge steep slope model 2. When the water flows away from the discharge steep slope model 2, the pressure measuring tube 3 contacts the discharge steep slope. The water flow pressure on the model 2 is detected, and then the pressure measuring tube 3 transmits the pressure to the connecting tube 4, so that the liquid height in the connecting tube 4 changes, and the water flow pressure on the discharge steep slope model 2 is intuitively observed, and the pressure measuring tube 3 fixed on the discharge steep slope model 2 is reinforced and fixed by using the reinforcement fixing mechanism 5. While the pressure measuring tube 3 is reinforced by the reinforcement fixing mechanism 5, the auxiliary stabilizing mechanism 6 further restricts the pressure measuring tube 3, so that the pressure measuring tube 3 can be stably fixed on the discharge steep slope model 2, reducing the possibility of the pressure measuring tube 3 falling off due to the vibration of the discharge steep slope model 2 caused by excessive water flow, and further improving the stability of the pressure measuring tube 3 fixed on the discharge steep slope model 2.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The reinforcement fixing mechanism 5 includes a fixing block 51 arranged on one side of the pressure measuring tube 3, the fixing block 51 is fixedly connected to the discharge steep slope model 2, a fixing block 52 is arranged on the side of the pressure measuring tube 3 away from the fixing block 51, a supporting sliding component 53 is arranged between the fixing block 52 and the discharge steep slope model 2, and a limiting component 54 is arranged between the fixing block 51 and the fixing block 52.

[0031] When one end of the pressure measuring tube 3 is fixed on the discharge steep slope model 2, one side of the pressure measuring tube 3 is in contact with the fixed block 1 51, and then the fixed block 2 52 is driven by the supporting sliding component 53 to move toward the fixed block 1 51, so that the fixed block 1 51 and the fixed block 2 52 clamp and fix the pressure measuring tube 3, and then the limiting component 54 fixes the fixed block 2 52, so that the fixed block 1 51 and the fixed block 2 52 are stably clamped on the pressure measuring tube 3, thereby improving the stability of the pressure measuring tube 3 fixed on the discharge steep slope model 2, and by fixing the pressure measuring valve on the discharge steep slope model 2, the fixed block 1 51 and the fixed block 2 52 are used to further fix the pressure measuring tube 3, so that when the water flows through the discharge steep slope model 2, the possibility of the pressure measuring tube 3 falling off due to the vibration of the discharge steep slope model 2 is reduced.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The supporting sliding assembly 53 includes a sliding rail 531 fixed on the discharge steep slope model 2, and a sliding block 532 is slidably connected to the sliding rail 531, and the sliding block 532 is fixedly connected to the fixed block 2 52.

[0033] When the pressure measuring tube 3 is inserted into the discharge steep slope model 2, the side of the pressure measuring tube 3 contacts the fixed block 1 51, and then the sliding block 532 is allowed to slide on the sliding rail 531, and the sliding block 532 drives the fixed block 2 52, and the fixed block 2 52 contacts the pressure measuring tube 3, and the fixed block 1 51 and the fixed block 2 52 clamp the pressure measuring tube 3. When the sliding block 532 slides on the sliding rail 531, the sliding block 532 drives the fixed block 2 52 to move, so that the fixed block 2 52 can be easily contacted with the pressure measuring tube 3.

[0034] Reference Figure 4 and Figure 5 The limiting assembly 54 includes two limiting plates 541 symmetrically fixed on the fixed block 52, and the two limiting plates 541 penetrate the fixed block 51. A clamping block 543 is arranged between one of the limiting plates 541 and the fixed block 51, and the clamping block 543 and the fixed block 51 are slidably connected. The clamping block 543 and the limiting plate 541 are both provided with clamping teeth 542, and the directions are opposite. A resistance spring 544 is arranged between the clamping block 543 and the fixed block 51, and both ends of the resistance spring 544 are fixedly connected with the clamping block 543 and the fixed block 51.

[0035] When the sliding block 532 drives the fixed block 2 52 to move, the fixed block 2 52 drives the limiting plate 541 to make the limiting plate 541 slide on the fixed block 1 51. When the limiting plate 541 slides, the inclined surface of the engaging tooth 542 on the limiting plate 541 contacts the inclined surface of the engaging tooth 542 on the engaging block 543, so that the engaging block 543 slides on the fixed block 1 51, and then the engaging block 543 squeezes the contact spring 544. When the fixed block 2 52 completely contacts the pressure measuring tube 3, the contact spring 544 pushes the engaging block 543, so that the engaging tooth 542 on the engaging block 543 is stuck with the engaging tooth 542 on the limiting plate 541. The part of the fixed block 2 52 that contacts the pressure measuring tube 3 is made of rubber material, so that the engaging teeth 542 on the limit plate 541 can be completely engaged with the engaging block 543, reducing the possibility of small errors causing the engaging teeth 542 on the engaging block 543 and the engaging teeth 542 on the limit plate 541 to be misaligned. By allowing the fixed block 2 52 to drive the limit plate 541 when moving, the limit plate 541 is allowed to move unidirectionally on the fixed block 1 51 under the action of the engaging block 543, so that the fixed block 2 52 remains fixed when it contacts the pressure measuring tube 3, thereby allowing the fixed block 2 52 to remain stable when it contacts the pressure measuring tube 3.

[0036] Reference Figure 4 and Figure 5 A sliding groove 546 is provided on the fixed block 51 , and a release block 545 is provided in the sliding groove 546 . The release block 545 is slidably connected to the fixed block 51 , and the release block 545 is fixedly connected to the clamping block 543 .

[0037] When it is necessary to remove the pressure measuring tube 3 from the leakage steep slope model 2, the release block 545 is directly moved in the sliding groove 546, and the release block 545 drives the clamping block 543 to move the clamping block 543 away from the limiting plate 541, and then the fixed block 2 52 is moved away from the fixed block 1 51. The pressure measuring tube 3 is free from the interference of the fixed block 2 52, and then the pressure measuring tube 3 is normally separated from the leakage steep slope model 2. By letting the release block 545 slide in the sliding groove 546, the release block 545 drives the clamping block 543 away from the limiting plate 541, so that the fixed block 2 52 can be easily moved in the direction away from the pressure measuring tube 3.

[0038] Reference Figure 3 , Figure 4 and Figure 5 The auxiliary stabilizing mechanism 6 includes two arc-shaped clamping blocks 61 symmetrically arranged on both sides of the pressure measuring tube 3 , support rods 62 are fixed on the two arc-shaped clamping blocks 61 , and a synchronous moving component 63 is arranged between the two support rods 62 .

[0039] When the second fixed block 52 is moved toward the first fixed block 51, the second fixed block 52 drives the limit plate 541, and the limit plate 541 contacts the synchronous moving component 63, and then the synchronous moving component 63 simultaneously drives the two support rods 62 to move toward the direction of the pressure measuring tube 3, and then the arc-shaped clamping blocks 61 on the two support rods 62 are clamped on the pressure measuring tube 3, and the pressure measuring tube 3 is further clamped and fixed by the arc-shaped clamping blocks 61, and at the same time, the contact surfaces of the two arc-shaped clamping blocks 61 are provided with inclined surfaces. Under the action of the inclined surface on the arc clamping block 61, the pressure measuring tube 3 is made to contact in the direction of the leakage steep slope model 2. When the fixed rod block 2 moves, the fixed block 2 52 drives the limit plate 541, and the limit plate 541 drives the synchronous moving component 63. The synchronous moving component 63 simultaneously drives the two arc clamping blocks 61 to contact the pressure measuring tube 3, thereby further improving the stability of the pressure measuring tube 3 fixed on the leakage steep slope model 2 and reducing the possibility of separation between the pressure measuring tube 3 and the leakage steep slope model 2.

[0040] Reference Figure 4 and Figure 5The synchronous moving component 63 includes two moving inclined blocks 631 symmetrically slidably connected to the fixed block 51, the two moving inclined blocks 631 are fixedly connected to the corresponding support rods 62, the inclined surfaces of the two moving inclined blocks 631 are slidably connected to the moving inclined blocks 632, the two moving inclined blocks 632 are fixed with connecting rods 633, a connecting rod 634 is fixed between the two connecting rods 633, and the end of the limiting plate 541 away from the fixed block 52 conflicts with the connecting rod 634.

[0041] When the limit plate 541 moves, the limit plate 541 pushes the second connecting rod 634, the second connecting rod 634 drives the first connecting rod 633, and the first connecting rod 633 drives the second moving inclined block 632, so that the second moving inclined block 632 slides on the inclined surface of the first moving inclined block 631, and the first moving inclined block 631 drives the support rod 62 to move under the restriction of the first fixed block 51 and the push of the second moving inclined block 632. When the second fixed block 52 contacts the pressure relief pipe, the second fixed block 52 drives the limit plate 541, the limit plate 541 pushes the second connecting rod 634, the second moving inclined block 632 pushes the first moving inclined block 631, and the first moving inclined block 631 drives the support rod 62 to move toward the pressure measuring tube 3, so that the support rod 62 can drive the arc clamping block 61 to contact the pressure measuring tube 3.

[0042] Reference Figure 4 and Figure 5 A support spring 635 is provided between the second connecting rod 634 and the first fixed block 51 , and both ends of the support spring 635 are fixedly connected to the second connecting rod 634 and the first fixed block 51 .

[0043] When the fixed block 2 52 does not contact the pressure measuring tube 3, the support spring 635 limits the connecting rod 2 634, the connecting rod 2 634 limits the connecting rod 1 633, the connecting rod 1 633 limits the moving inclined block 2 632, and the moving inclined block 2 632 limits the moving inclined block 1 631, so that the support rod 62 on the moving inclined block 1 631 drives the arc clamping block 61 to maintain an open state. By using the support spring 635 to limit the support rod 62, the two arc clamping blocks 61 can be kept in an open state, reducing the possibility of the arc clamping block 61 delaying the fixation of the pressure measuring tube 3.

[0044] Working principle: When conducting a slope pressure test of a reservoir discharge steep slope, first fix the pressure measuring tube 3 at the bottom of the discharge steep slope model 2, and the side of the pressure measuring tube 3 contacts the fixed block 1 51. Then let the sliding block 532 slide on the sliding rail 531, let the sliding block 532 drive the fixed block 2 52, let the fixed block 2 52 contact the pressure measuring tube 3, let the fixed block 1 51 and the fixed block 2 52 clamp the pressure measuring tube 3, and the fixed block 2 52 drives the limit plate 541, and let the limit plate 541 contact the fixed block 1 51. When the limit plate 541 slides, the inclined surface of the engaging tooth 542 on the limit plate 541 contacts the inclined surface of the engaging tooth 542 on the engaging block 543, allowing the engaging block 543 to slide on the fixed block 1 51, and then the engaging block 543 squeezes the contact spring 544. When the fixed block 2 52 completely contacts the pressure measuring tube 3, the contact spring 544 pushes the engaging block 543, allowing the engaging tooth 542 on the engaging block 543 to be clamped together with the engaging tooth 542 on the limit plate 541, so that the fixed block 1 51 and the fixed block 2 are completely in contact with the pressure measuring tube 3. The block 2 52 clamps the pressure measuring tube 3. When the fixed block 2 52 drives the limit plate 541, the limit plate 541 pushes the connecting rod 2 634, the connecting rod 2 634 drives the connecting rod 1 633, and the connecting rod 1 633 drives the moving inclined block 2 632, so that the moving inclined block 2 632 slides on the inclined surface of the moving inclined block 1 631, and the moving inclined block 1 631 drives the support rod 62 to move under the restriction of the fixed block 1 51 and the push of the moving inclined block 2 632, so that the support rod 62 drives the arc clamping block 61 toward The pressure measuring tube 3 moves in the direction of the water flow, and then the pressure measuring tube 3 is further fixed, and then the water in the reservoir model is allowed to flow out from the discharge port 1 at the corner of the reservoir model. When the water flows out from the discharge port, the water flows away from the discharge steep slope model 2. When the water flows away from the discharge steep slope model 2, the pressure measuring tube 3 detects the water flow pressure on the discharge steep slope model 2, and then the pressure measuring tube 3 transmits the pressure to the connecting tube 4, so that the liquid height in the connecting tube 4 changes, and the water flow pressure on the discharge steep slope model 2 is intuitively observed.
