[0024] As a further optimization scheme of the present invention, the inlet section is connected with a first solenoid valve, and the upper end of the pipe body section is provided with a second solenoid valve near the inlet section, and the second solenoid valve is lower than the outlet section.

[0025] As a further optimization scheme of the present invention, two inverted siphon pressure steel pipes are provided, and the two inverted siphon pressure steel pipes are interconnected through an X-shaped pipe.

[0026] As a further optimization solution of the present invention, a plurality of X-shaped pipes are provided, and the X-shaped pipes are provided with a bending position on the inverted siphon pressure steel pipe.

[0027] The present invention also discloses a method for using an inverted siphon pressure steel pipe installation device, which is applicable to the inverted siphon pressure steel pipe installation device and comprises the following steps:

[0028] Step 1: first excavate a foundation pit, excavate a foundation pit on the ground for burying the embedded parts, install the embedded parts in the foundation pit, fill and fix them, install the settlement adjustment part on the upper surface of the embedded parts, install an upper connecting plate on the upper surface of the settlement adjustment part, fix the casing part on the upper surface of the upper connecting plate with screws, and the inverted siphon pressure steel pipe is sleeved and fixed in the casing part, and adjacent inverted siphon pressure steel pipes are spliced ​​with each other;

[0029] Afterwards, a distance sensor is installed on the bottom surface of the upper connecting plate;

[0030] Step 2: Settlement monitoring: using a distance sensor to monitor the distance between the inverted siphon penstock and the ground, the preset distance is H, and the distance between the inverted siphon penstock and the bottom surface monitored in real time is set to H1;

[0031] If H1 < H, it proves that the inverted siphon pressure steel pipe has settled;

[0032] If H1 = H, it proves that the inverted siphon pressure steel pipe has not settled;

[0033] Step 3: When it is monitored that the inverted siphon pressure steel pipe has settled, the distance sensor feeds back the monitored information to the controller arranged at one end of the power mechanism. The controller controls the power mechanism to inflate the corresponding pressure chamber. After inflation, the lifting rod lifts the inverted siphon pressure steel pipe to rise, so that the height of the inverted siphon pressure steel pipe is restored.

[0034] The beneficial effect of the present invention is that when it is monitored that the inverted siphon pressure steel pipe has settled, the distance sensor feeds back the monitored information to the controller arranged at one end of the power mechanism. The controller controls the power mechanism to inflate the corresponding pressure chamber. After inflation, the lifting rod lifts the inverted siphon pressure steel pipe to rise, so that the height of the inverted siphon pressure steel pipe is restored, solving the problem of settlement.

[0035] When the inverted siphon pressure steel pipe of the present invention settles, the soil pushes the inclined surfaces on the two pressure push blocks, so that the reinforcing support plate extends from the side surface of the upper end plate of the I-shaped support plate, increasing the support surface between the bottom of the I-shaped support plate and the soil, thereby increasing the resistance during the settlement process and reducing the degree of settlement.

[0036] When the inverted siphon pressure steel pipe of the present invention continues to settle, it can continue to use the conical thorns to successively pierce other hollow balls, so that the soil reinforcing agent in the hollow balls flows out, reinforcing the soil multiple times, improving the stability of the device, and being able to avoid the phenomenon that the inverted siphon pressure steel pipe settles to a large extent.

[0037] The rubber layer of the present invention has a good elastic buffering effect. When the inverted siphon pressure steel pipe vibrates, the rubber layer has a shock-absorbing effect on the inverted siphon pressure steel pipe, reducing the phenomenon that the installation device of the inverted siphon pressure steel pipe vibrates severely due to the water source impacting the inverted siphon pressure steel pipe and vibrating, and further reducing the settlement phenomenon.

[0038] When the water in the inverted siphon pressure steel pipe of the present invention flows at the bending position, it can be interconnected through the inclined X-shaped pipes. The water flows in the two inverted siphon pressure steel pipes converge and offset each other, reducing the water hammer phenomenon at the bending position on the inverted siphon pressure steel pipe, thereby reducing the pressure of the inverted siphon pressure steel pipe installation device on the ground and reducing the settlement phenomenon.

[0039] In the present invention, when the distance sensor detects that the inverted siphon pressure steel pipe has settled, the controller is used to control the third solenoid valve to close, and the fourth solenoid valve and the corresponding fifth solenoid valve to open, so that the water pumped out by the water pump can flow into the pressure chamber through the output pipe, auxiliary pipe, branch pipe, and docking pipe in sequence, thereby achieving the purpose of lifting the casing part. When the casing part rises, the height position of the inverted siphon pressure steel pipe is restored to avoid settling of the inverted siphon pressure steel pipe. There is no need to set up an additional regulating mechanism, which is simple, convenient and low in cost.

[0040] In the present invention, when the inlet section and a section of the pipe body section close to the inlet section are filled with water, the first solenoid valve is closed and the second solenoid valve is opened. Since the second solenoid valve is lower than the outlet section, a siphon phenomenon can be formed. Therefore, the water source at the inlet section can automatically flow out from the outlet section. There is no need to fill the water source in the overall pipeline inside the inverted siphon pressure steel pipe in advance, and the energy consumption is low. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0050] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0051] As Figures 1 to 8 shown, an installation device for an inverted siphon penstock includes a casing part 2, a settlement adjustment part 3, an upper connecting plate 4 and a lower embedded part 5. The casing part 2 is installed and sleeved on the outer circle of the inverted siphon penstock 1 and is used to fix the inverted siphon penstock 1. The settlement adjustment part 3 is vertically distributed. The upper connecting plate 4 is connected to the upper end of the settlement adjustment part 3, and the lower embedded part 5 is connected to the lower end of the settlement adjustment part 3. The upper connecting plate 4 is used for fixed connection with the casing part 2, and the lower embedded part 5 is pre-embedded and fixed in the ground. When installing the inverted siphon penstock 1, first excavate a foundation pit, excavate a foundation pit on the ground for burying the lower embedded part 5, install the lower embedded part 5 in the foundation pit and fill it with solid materials, install the settlement adjustment part 3 on the upper surface of the lower embedded part 5, install the upper connecting plate 4 on the upper surface of the settlement adjustment part 3, fix the casing part 2 on the upper surface of the upper connecting plate 4 with screws, and the inverted siphon penstock 1 is sleeved and fixed in the casing part 2, and adjacent inverted siphon penstocks 1 are spliced with each other; then install the distance sensor 8 on the bottom surface of the upper connecting plate 4.

[0052] During operation, the distance sensor 8 is used to monitor the distance between the inverted siphon penstock 1 and the ground. The preset distance is H, and the distance between the inverted siphon penstock 1 and the bottom surface monitored in real time is set as H1;

[0053] If H1 < H, it proves that the inverted siphon penstock 1 has settled;

[0054] If H1 = H, it proves that the inverted siphon penstock 1 has not settled.

[0055] The settlement adjustment part 3 of the present invention includes a lifting cylinder 301, a lifting rod 302, a spring 303 and a pressure chamber 304. The bottom of the lifting cylinder 301 is fixedly connected to the lower embedded part 5. The lower end of the lifting rod 302 is telescopically arranged inside the lifting cylinder 301. The upper end of the lifting rod 302 is movably extended out of the top of the lifting cylinder 301 and is fixedly connected to the bottom surface of the upper connecting plate 4. The spring 303 is fixedly connected between the inner bottom surface of the lifting cylinder 301 and the bottom surface of the lifting rod 302. A pressure chamber 304 is formed between the inner bottom surface of the lifting cylinder 301 and the bottom surface of the lifting rod 302. A docking pipe 305 is provided on one side of the lowering tube 301, and the docking pipe 305 is connected with the interior of the pressure chamber 304; wherein, the input end of the docking pipe 305 is connected to the power mechanism of the inverted siphon pressure steel pipe 1; when the settlement phenomenon of the inverted siphon pressure steel pipe 1 is detected, the distance sensor 8 feeds back the monitored information to the controller set at one end of the power mechanism, and the controller controls the power mechanism to inflate the corresponding pressure chamber 304. After inflation, the lifting rod 302 lifts the inverted siphon pressure steel pipe 1 to rise, so that the height of the inverted siphon pressure steel pipe 1 is restored, thereby solving the settlement problem.

[0056] In order to further reduce the occurrence of settlement, the lower embedded part 5 in the present invention includes an I-shaped I-shaped support plate 501, which is pre-buried in the ground and is not prone to settlement. The installation is relatively stable. Sliding grooves 502 are arranged on both sides of the lower end of the I-shaped support plate 501, and a sliding plate 504 is slidably arranged in the sliding groove 502. A reinforcing support plate 503 is fixedly arranged on the upper end of the sliding plate 504, and a pressure push block 505 is fixedly arranged on the lower end of the sliding plate 504. The reinforcing support plate 503 is fixedly arranged on the upper end of the sliding plate 504. 3 and the pressure push block 505 are movably fitted on the upper and lower surfaces of the bottom plate body of the I-shaped support plate 501 respectively; the two corresponding pressure push blocks 505 are provided with inclined surfaces on the sides close to each other. When the inverted siphon pressure steel pipe 1 settles, the soil pushes the inclined surfaces on the two pressure push blocks 505, so that the reinforced support plate 503 extends from the side of the upper surface of the lower end plate body of the I-shaped support plate 501 to increase the support surface between the bottom of the I-shaped support plate 501 and the soil, thereby increasing the resistance during the settlement process and reducing the degree of settlement.

[0057] In actual use, a hollow ball 506 is fixedly provided on the inner wall of the sliding groove 502. There are multiple hollow balls 506, and the multiple hollow balls 506 are evenly distributed. The multiple hollow balls 506 are supported between the sliding plate 504 and the inner wall of the sliding groove 502, so that the sliding plate 504 is located near the middle of the I-shaped support plate 501 in the initial state.

[0058] Furthermore, the hollow ball 506 is filled with soil reinforcement, and a long plate 507 is fixedly provided on one side of the sliding plate 504 close to the hollow ball 506, and a conical thorn 508 is fixedly provided on the upper surface of the long plate 507, and the conical thorn 508 corresponds to the bottom surface of the hollow ball 506; such as: super glue, when the super glue can be stored in the closed hollow ball 506 for a period of time depending on the type, usually at least one year, therefore, when the inverted siphon pressure steel pipe 1 settles, the conical thorn 508 can be used to strengthen the process of the support plate 503 moving outward. 8 A hollow ball 506 close to the sliding plate 504 is punctured first, so that the soil reinforcement in the hollow ball 506 flows out, thereby reinforcing the soil around the lower embedded part 5 and preventing the inverted siphon pressure steel pipe 1 from continuing to sink seriously. When the inverted siphon pressure steel pipe 1 continues to sink, the conical thorns 508 can be used to puncture other hollow balls 506 one after another, so that the soil reinforcement in the hollow ball 506 flows out, and the soil is reinforced multiple times to improve the stability of the device, which can prevent the inverted siphon pressure steel pipe 1 from sinking to a large extent.

[0059] It should be noted that the hollow ball 506 is made of plastic or other materials. When the sliding plate 504 moves, the hollow ball 506 can be flattened and squeezed between the sliding groove 502 and the sliding plate 504 without affecting the movement of the sliding plate 504 .

[0060] The factors that cause the inverted siphon penstock 1 to sink include not only the gravity of the inverted siphon penstock 1 itself, but also the water source. When a large amount of water is transported in the inverted siphon penstock 1, first, the gravity of the water is relatively large, and second, the water flow will cause the inverted siphon penstock 1 to vibrate, thereby aggravating the sinking. Therefore, the present invention reduces the problem of aggravating the sinking of the inverted siphon penstock 1 due to the water source from two directions:

[0061] In the first aspect, the casing part 2 of the present invention includes an outer casing 201, an upper fixing plate 202, a lower fixing plate 203 and a fixed bottom plate 205. The outer casing 201 is semi-annular, and the two outer casings 201 are jointly sleeved on the outer ring of the inverted siphon pressure steel pipe 1 to form an annular shape and are sleeved and fixed on the outer ring of the inverted siphon pressure steel pipe 1; the upper fixing plate 202 is fixedly connected to the upper end of the outer casing 201, and the lower fixing plate 203 is fixedly connected to the lower end of the outer casing 201. The two upper fixing plates 202 and the two lower fixing plates 203 are fixed by screws and nuts, and the fixed bottom plate 205 is fixed Connected to the bottom surface of the lower fixed plate 203, the fixed bottom plate 205 is fixed to the upper surface of the upper connecting plate 4 by screws; a rubber layer 204 is fixedly provided at the inner ring of the outer pipe sleeve 201, and the rubber layer 204 is in contact with the outer ring surface of the inverted siphon penstock 1; the rubber layer 204 has a good elastic buffering effect. When the inverted siphon penstock 1 vibrates, the rubber layer 204 has a shock-absorbing effect on the inverted siphon penstock 1, thereby reducing the phenomenon that the inverted siphon penstock installation device vibrates severely due to the vibration of the inverted siphon penstock 1 caused by the impact of the water source, and further reducing the settlement phenomenon.

[0062] The second aspect: two inverted siphon penstocks 1 are provided, and the water delivery pressure is relieved by the two inverted siphon penstocks 1, the contact area of ​​the installation position between the inverted siphon penstocks 1 and the ground is increased, and the settlement phenomenon is reduced, and the two inverted siphon penstocks 1 are interconnected through an X-shaped pipe 11; there are multiple X-shaped pipes 11, and the X-shaped pipes 11 are provided with a bending position on the inverted siphon penstock 1; when water in the inverted siphon penstock 1 flows at the bending position, it can be interconnected through the inclined X-shaped pipe 11, and the water flows in the two inverted siphon penstocks 1 converge and offset each other, reducing the water hammer phenomenon of the water flow on the bending position on the inverted siphon penstock 1, thereby reducing the pressure of the inverted siphon penstock installation device on the ground and reducing the settlement phenomenon.

[0063] The power mechanism of the inverted siphon pressure steel pipe 1 in the present invention includes a water pump 6. The inverted siphon pressure steel pipe 1 includes an inlet section 101, a pipe body section 102 and an outlet section 103. The inlet section 101 is higher than the outlet section 103, and the pipe body section 102 is lower than the inlet section 101 and the outlet section 103. One end of the water pump 6 is connected to a water source at one end of the inlet section 101. When the water pump 6 is started, the water source is sucked into the inlet section 101, and the water source passes through the inlet section 101 and the pipe body section 102 in sequence and is discharged from the end of the outlet section 103.

[0064] In order to facilitate on-site adjustment and repair of the settlement of the inverted siphon pressure steel pipe 1, the output pipe 61 on the water pump 6 is connected to the inlet section 101, and a third solenoid valve 601 is provided in the output pipe 61, and the third solenoid valve 601 is used to control the connection between the output pipe 61 and the inlet section 101; an auxiliary pipe 7 is provided on the output pipe 61, and the auxiliary pipe 7 is laid along the inverted siphon pressure steel pipe 1, and a fourth solenoid valve 701 is provided at one end of the auxiliary pipe 7 connected to the output pipe 61; a branch pipe 702 is provided on the auxiliary pipe 7, and the branch pipe 702 is connected to the corresponding docking pipe 305, and a fifth solenoid valve 7 is provided in the docking pipe 305. 03; When the distance sensor 8 detects that the inverted siphon pressure steel pipe 1 has settled, the controller is used to control the third solenoid valve 601 to close, and the fourth solenoid valve 701 and the corresponding fifth solenoid valve 703 to open, so that the water pumped out by the water pump 6 can flow into the pressure chamber 304 through the output pipe 61, the auxiliary pipe 7, the branch pipe 702, and the docking pipe 305 in sequence, thereby achieving the purpose of lifting the casing part 2. When the casing part 2 rises, the height position of the inverted siphon pressure steel pipe 1 is restored to avoid the inverted siphon pressure steel pipe 1 from settling. There is no need to set up additional control mechanisms, which is simple, convenient, and low-cost.

[0065] It should be noted that the controller is not shown in the figure, and can be installed in an electric control box used in conjunction with the water pump 6. This is existing technology and will not be described in detail here.

[0066] Considering that the inverted siphon pressure steel pipe 1 usually has a large diameter, when the water pump 6 is turned on, water needs to be filled in the entire pipeline of the inverted siphon pressure steel pipe 1 so that there is no air in the pipeline of the inverted siphon pressure steel pipe 1 in order to basically keep the water at the inlet section 101 end flooded and discharged to the outlet section 103. However, the initial startup power is relatively large, and it takes a period of time to meet the purpose of filling the entire pipeline of the inverted siphon pressure steel pipe 1, and the energy consumption is still relatively large. Therefore, in the present invention, 1011 is connected and arranged above the inlet section 101, and a first solenoid valve 104 is arranged on 1011. A second solenoid valve 105 is arranged at a position near the inlet section 101 on the upper end of the pipe body section 102, and the second solenoid valve 105 is lower than the outlet section. 103; when working, the first solenoid valve 104 is opened and the second solenoid valve 105 is closed, and the water pump 6 is started. The water pump 6 can draw water into the inlet section 101 and the section of the pipe body section 102 close to the inlet section 101, and the excess air is discharged from 1011. When the inlet section 101 and the section of the pipe body section 102 close to the inlet section 101 are filled with water, the first solenoid valve 104 is closed and the second solenoid valve 105 is opened. Since the second solenoid valve 105 is lower than the outlet section 103, a siphon phenomenon can be formed. Therefore, the water at the inlet section 101 can automatically flow out from the outlet section 103, and there is no need to fill the water source in the overall pipeline inside the inverted siphon pressure steel pipe 1 in advance, and the energy consumption is low.

[0067] During specific use, a water level sensor can be provided in the inlet section 101. The water level sensor is used to monitor whether the water level in the inlet section 101 has reached the level of filling the inside of the inlet section 101. The water level sensor is used in conjunction with the controller, the first solenoid valve 104 and the second solenoid valve 105 to achieve the purpose of automatic control, which is convenient and practical.

[0068] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
