Description

Technical Field

[0001] This utility model is a water conservancy project seepage prevention quality monitoring device, belonging to the field of water conservancy engineering. Background Technology

[0002] Cutoff walls are commonly used structural components in water conservancy projects. During use, their seepage prevention quality needs to be monitored. A transparent cylinder containing water is installed at the bottom of the cutoff wall. Inside the cylinder, a piston, pressurized by a driving component, slides and is connected to the cutoff wall. A sealing ring is installed between the cylinder and the wall. The piston, under pressure from the driving component, squeezes the water inside the cylinder, causing it to seep into the wall. Observing the water level changes in the cylinder allows for monitoring the cutoff wall's seepage prevention quality. However, the support frame on the cylinder needs to be installed at the bottom of the wall using expansion bolts. Installing these bolts requires drilling holes in the wall, which can affect its structure. Therefore, a water conservancy project seepage prevention quality monitoring device needs to be designed that allows the transparent cylinder to be installed on the cutoff wall without the need for expansion bolts. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water conservancy project seepage prevention quality monitoring device to solve the problems mentioned in the background technology. This utility model does not require the use of expansion bolts to fix the transparent cylinder to the seepage prevention wall, thus reducing the impact on the seepage prevention wall structure.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a water conservancy project seepage prevention quality monitoring device, comprising a transparent cylinder, the outer surface of which is machined with scale lines, a sealing ring installed on the lower surface of which is installed, a cap fitted on the upper end of which is provided, a vertical hole opened in the middle of the upper surface of which is provided, a column rod inserted into which is inserted, a cylinder body installed on the upper end of which is provided, a piston for squeezing water in which is provided on the lower end of which is provided, the piston being slidably installed in which is provided, a ring fixedly connected to the lower end of which is provided, a pressure ring fitted on which is provided, two L-shaped plates symmetrically connected and fixedly connected to the outer surface of which is provided, a support plate fixedly connected to the lower end of the vertical part of which is provided, a detachable counterweight installed on the upper surface of which is provided, and support members for stably placing the transparent cylinder on the top of the seepage prevention wall installed on the two parallel sides of which are provided.

[0005] Furthermore, the counterweight includes a counterweight block, and a plurality of counterweight blocks arranged vertically are provided on the upper side of the pallet. Two through holes are formed on the upper surface of the counterweight block, and two positioning rods that cooperate with the through holes are installed on the upper surface of the pallet. The positioning rods pass through the through holes.

[0006] Furthermore, rectangular grooves are provided on the opposite surfaces of the two pallets, and two small holes communicating with the rectangular grooves are provided on the upper surface of the pallets. A threaded head is fixedly connected to the lower end of the positioning rod, and the lower end of the threaded head passes through the small hole and is threadedly connected to a nut. The nut is set in the rectangular groove. A threaded hole that mates with the threaded head is provided at the middle position of the upper surface of the positioning rod, and the threaded head on one positioning rod is threadedly connected to the threaded hole on the other positioning rod.

[0007] Furthermore, the support member includes a support plate, and support plates are installed on two parallel sides of the support plate. The support plates are arranged perpendicularly to the support plate. A rectangular tube is sleeved on the end of the support plate away from the support plate. A positioning screw for limiting the relative position between the support plate and the rectangular tube is threaded on the side of the upper surface of the rectangular tube near the support plate. A vertical screw hole is opened on the side of the upper surface of the rectangular tube away from the positioning screw. A support screw is threaded in the vertical screw hole. A handle is fixedly connected to the upper end of the support screw. A base is installed on the lower end of the support screw.

[0008] Furthermore, a threaded sleeve is installed at the position of the positioning screw on the rectangular tube, the positioning screw is threaded into the threaded sleeve, and the threaded sleeve communicates with the internal space of the rectangular tube.

[0009] Furthermore, a bottom ring is fixedly connected to the lower end of the transparent cylinder. The outer diameter of the bottom ring is the same as the outer diameter of the sealing ring. Multiple column heads are evenly fixed on the lower surface of the bottom ring. The upper surface of the sealing ring is recessed downward to form multiple evenly arranged limiting holes that cooperate with the column heads. The column heads are inserted into the limiting holes.

[0010] The beneficial effects of this utility model are:

[0011] 1. Place the cap on the upper end of the transparent cylinder, then place the pressure ring on the cap so that the pressure ring contacts the sealing ring, placing the sealing ring between the transparent cylinder and the seepage barrier. Then place multiple counterweights arranged vertically on the support plate. Under the pressure of the counterweights, the cap applies pressure to the transparent cylinder, thereby improving the sealing effect of the sealing ring.

[0012] 2. After the threaded head on the positioning rod extends through the small hole into the rectangular groove, tighten the nut to complete the assembly of the positioning rod and the support plate. Then, make the positioning rod pass through the through hole on the counterweight to restrict the relative position of the counterweight and the support plate. Screw the threaded head on one positioning rod into the threaded hole on another positioning rod to complete the assembly of two positioning rods. Repeat this process to complete the assembly of multiple positioning rods. This allows for the miniaturization of the positioning rod length. The number of positioning rods can be selected according to the number of counterweights, eliminating the need to manufacture long positioning rods.

[0013] 3. Adjust the length of the support plate inserted into the rectangular tube to move the support screw to the required position, that is, change the relative position of the support screw and the support plate until the support screw moves to the required position of the seepage barrier wall. Then, use the positioning screw to restrict the relative position of the support plate and the rectangular tube so that the base plate at the lower end of the support screw contacts the top of the seepage barrier wall. At this time, the four support screws and other components support the transparent cylinder. It is not necessary to use expansion bolts to fix the transparent cylinder to the seepage barrier wall, thus reducing the impact on the seepage barrier wall structure.

[0014] 4. Add a counterweight to the cylinder, and under the action of the counterweight, the rod will drive the piston to move downward in the transparent cylinder. The piston will squeeze the water in the transparent cylinder, and under the action of pressure, the water will tend to seep into the seepage barrier wall at an accelerated rate. The change of water level in the transparent cylinder can be observed through the scale line to monitor the seepage barrier quality. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a water conservancy project seepage prevention quality monitoring device, including a transparent cylinder 1, with scale lines processed on the outer surface of the transparent cylinder 1, and a sealing ring 3 installed on the lower surface of the transparent cylinder 1. The lower end of the transparent cylinder 1 is connected and fixed to a bottom ring 2, the outer diameter of the bottom ring 2 is the same as the outer diameter of the sealing ring 3, and a plurality of column heads 23 are uniformly fixed on the lower surface of the bottom ring 2. The upper surface of the sealing ring 3 is recessed downward to form a plurality of uniformly arranged limiting holes 22 that cooperate with the column heads 23, so that the column heads 23 are inserted into the limiting holes 22, realizing the insertion of the sealing ring 3 and the bottom ring 2. The bottom ring 2 increases the contact range between the sealing ring 3 and the transparent cylinder 1.

[0024] See Figure 1 and Figure 2 A cap 16 is fitted onto the upper end of the transparent cylinder 1. A vertical hole is opened in the middle of the upper surface of the cap 16, and a rod 17 is inserted into the vertical hole. A cylinder body 18 is installed on the upper end of the rod 17, and a piston 21 for squeezing water in the transparent cylinder 1 is installed on the lower end of the rod 17. The piston 21 is slidably installed in the transparent cylinder 1. A counterweight is added into the cylinder body 18, and under the action of the counterweight, the rod 17 drives the piston 21 to move downward in the transparent cylinder 1. The piston 21 squeezes the water in the transparent cylinder 1, so that the water tends to seep into the seepage barrier wall more quickly under the pressure. The change of water level in the transparent cylinder 1 can be observed through the scale line to monitor the seepage barrier quality.

[0025] See Figure 1 , Figure 2 , Figure 4 and Figure 5A ring 20 is fixedly connected to the lower end of the cap 16. A pressure ring 15 is fitted on the ring 20. Two L-shaped plates 14 are symmetrically fixed to the outer surface of the pressure ring 15. A support plate 11 is fixedly connected to the lower end of the vertical part of the L-shaped plate 14. Multiple counterweights 19 are arranged vertically on the upper side of the support plate 11. Two through holes 24 are opened on the upper surface of the counterweights 19. Two positioning rods 12 that cooperate with the through holes 24 are installed on the upper surface of the support plate 11. The positioning rods 12 pass through the through holes 24. Rectangular grooves 10 are opened on the opposite sides of the two support plates 11. Two small holes communicating with the rectangular grooves 10 are opened on the upper surface of the support plate 11. A threaded head 25 is fixedly connected to the lower end of the positioning rod 12. The lower end of the threaded head 25 passes through the small hole and is threadedly connected to a nut 26. The nut 26 is set in the rectangular groove. Inside the groove 10, a threaded hole is provided at the middle of the upper surface of the positioning rod 12 to mate with the threaded head 25. The threaded head 25 on the positioning rod 12 extends through the small hole into the rectangular groove 10, and then the nut 26 is screwed on to complete the assembly of the positioning rod 12 and the support plate 11. The positioning rod 12 passes through the through hole 24 on the counterweight 19 to restrict the relative position of the counterweight 19 and the support plate 11. The threaded head 25 on one positioning rod 12 is screwed into the threaded hole on another positioning rod 12 to complete the assembly of two positioning rods 12. This process is repeated to complete the assembly of multiple positioning rods 12, thereby miniaturizing the length of the positioning rod 12. The number of positioning rods 12 can be selected according to the number of counterweights 19, without the need to manufacture long positioning rods 12.

[0026] See Figure 1 Support plates 9 are installed on two parallel sides of the support plate 11. The support plates 9 are arranged perpendicularly to the support plate 11. A rectangular tube 5 is fitted onto the end of the support plate 9 away from the support plate 11. A threaded sleeve 7, communicating with the internal space of the rectangular tube 5, is installed on the upper surface of the rectangular tube 5 near the support plate 11. A positioning screw 8, used to limit the relative position of the support plate 9 and the rectangular tube 5, is threaded into the threaded sleeve 7. A vertical screw hole 13 is opened on the upper surface of the rectangular tube 5 away from the positioning screw 8. A support screw 4 is threaded into the vertical screw hole 13. A handle is fixed to the upper end of the support screw 4. The base plate 6 is installed at the end. The length of the support plate 9 inserted into the rectangular tube 5 is adjusted so that the support screw 4 is moved to the required position. That is, the relative position of the support screw 4 and the support plate 11 is changed until the support screw 4 is moved to the required position of the seepage barrier wall. Then, the positioning screw 8 is used to limit the relative position of the support plate 9 and the rectangular tube 5 so that the base plate 6 at the lower end of the support screw 4 contacts the top of the seepage barrier wall. At this time, the four support screws 4 and other components support the transparent cylinder 1. It is not necessary to use expansion bolts to fix the transparent cylinder 1 to the seepage barrier wall, thus reducing the impact on the seepage barrier wall structure.
