[0001] The utility model relates to the technical field of foundation pit construction, in particular to an automatic water replenishing device for a foundation pit water replenishing well. Background Technique

[0002] During the construction of deep foundation pits, due to the large variation range of the underground water level, it will often cause many changes in the additional stress around the foundation pit, resulting in cracking of the surrounding buildings due to settlement. Before the excavation of the foundation pit, it is necessary to equip observation wells to observe the underground water level and reduce the adverse impact of foundation pit dewatering on the settlement of surrounding buildings by means of construction water replenishment during the construction period.

[0003] For example, the application number: CN202222383535.4, the utility model discloses an automatic water replenishing device for a foundation pit water replenishing well, which relates to the technical field of foundation pit construction, including a water tank and a siphon tube. A sealing door is installed on the side of the water tank, a water inlet pipe is installed on the sealing door, a cover plate is installed on the top of the water tank, and an anti-blocking mechanism is installed on the cover plate. Compared with the prior art, the utility model injects and stores water into the water tank through the water inlet pipe, connects the water tank with the observation well by using the siphon tube, the first water pipe and the second water pipe.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 4 shown, an automatic water replenishing device for a foundation pit water replenishing well provided by the present invention includes a water tank 1, a filter cartridge 2, a water pump 3 and a water inlet pipe 4. The right side of the top of the water tank 1 is fixedly connected to the bottom of the water pump 3. The output end of the water pump 3 is communicated with one end of the water inlet pipe 4. The bottom of the surface of the filter cartridge 2 is fixedly connected to the bottom of the inner wall surface of the water tank 1. The other end of the water inlet pipe 4 is communicated with the bottom of the right side of the water tank 1. Both sides of the right side of the inner wall of the water tank 1 are fixedly connected with connecting plates 5. A contact sensor 6 is arranged inside the connecting plate 5. The input end of the water pump 3 is communicated with an external water source through a conduit. The front side of the top of the water tank 1 is fixedly connected with a control box 7. A floating plate 8 is arranged on the right side of the inner top of the water tank 1. Bumps 9 are fixedly connected to both the top and the bottom of the right side of the floating plate 8. An anti-offset mechanism 10 is provided on the left side of the top of the floating plate 8. A replacement mechanism 11 is fixedly connected to the outside of the contact sensor 6. The contact sensor 6 and the water pump 3 are both electrically connected to the control box 7 through wires.

[0024] Referring to Figure 4 , the anti-offset mechanism 10 includes a limiting groove 101. The limiting groove 101 is opened on the left side of the top of the floating plate 8. The inner wall of the limiting groove 101 is slidably connected with a limiting rod 102. The top of the limiting rod 102 is fixedly connected to the right side of the inner top of the water tank 1. The bottom of the limiting rod 102 is fixedly connected to the right side of the inner bottom of the water tank 1. Anti-rotation grooves 103 are opened on both sides of the limiting rod 102. The inner wall of the anti-rotation groove 103 is slidably connected with anti-rotation blocks 104. The outside of the anti-rotation blocks 104 is fixedly connected to both sides of the inner wall of the limiting groove 101.

[0025] As a technical optimization solution of the present utility model, by providing an anti-offset mechanism 10, during the process of the floating plate 8 being pushed by the water surface, the sliding fit between the limiting rod 102 and the limiting groove 101 can be used to limit the floating plate 8 in the front-back, left-right directions, preventing the floating plate 8 from deviating from its current orientation during the up-and-down movement, which may cause the convex block 9 on the floating plate 8 to fail to contact the contact sensor 6. Additionally, by using the sliding connection between the anti-rotation block 104 and the anti-rotation groove 103, the floating plate 8 is rotationally limited, preventing the floating plate 8 from rotating and causing the convex block 9 on the floating plate 8 to fail to contact the contact sensor 6.

[0026] Reference Figure 3 , the replacement mechanism 11 includes a plugging column 111. The inner side of the plugging column 111 is fixedly connected to the outer side of the contact sensor 6. A plugging groove 112 is formed on the inner side of the connecting plate 5. The plugging column 111 is plugged into the plugging groove 112. An inlay groove 113 is formed on the inner wall of the plugging groove 112, and an inlay ring 114 is inlaid inside the inlay groove 113. The inlay ring 114 is sleeved on the surface of the plugging column 111.

[0027] As a technical optimization solution of the present utility model, by providing a replacement mechanism 11, when the contact sensor 6 is in use and if it is damaged, the user can directly pull the contact sensor 6, causing the plugging column 111 to no longer be plugged into the plugging groove 112. Subsequently, the inlay ring 114 will disengage from the inlay groove 113, and then the contact sensor 6 can be replaced, thus facilitating the rapid replacement of the contact sensor 6.

[0028] Reference Figure 3 , a waterproof sleeve 12 is sleeved on the surface of the contact sensor 6. A magnetic ring 13 is fixedly connected to the outer side of the waterproof sleeve 12. A connecting groove 14 is formed on the inner side of the connecting plate 5, and the outer side of the inner wall of the connecting groove 14 is magnetically adsorbed to the inner side of the magnetic ring 13.

[0029] As a technical optimization solution of the present utility model, by providing the waterproof sleeve 12, the magnetic ring 13 and the connecting groove 14, first, the waterproof sleeve 12 can cover and waterproof the contact sensor 6 to prevent the contact sensor 6 from being damaged due to direct contact with water. Then, by using the magnetic ring 13 and the connecting groove 14, when the waterproof sleeve 12 is damaged after long-term use, the user can directly pull off the waterproof sleeve 12, causing the magnetic ring 13 to no longer be magnetically adsorbed to the connecting groove 14, and then the waterproof sleeve 12 can be replaced.

[0030] Reference Figure 3 , an anti-slip ring 15 is sleeved on the surface of the waterproof sleeve 12. There are four anti-slip rings 15 and they are evenly distributed at equal intervals.

[0031] As a technical optimization solution of the present utility model, by providing an anti-slip ring 15, when the user needs to remove and replace the waterproof sleeve 12, the user's hand can contact the waterproof sleeve 12 through the anti-slip ring 15, which increases the friction between the user's hand and the waterproof sleeve 12 and prevents the situation of slipping caused by too low friction.

[0032] Reference Figure 4 , both sides of the floating board 8 are fixedly connected with wooden boards 16, and both sides of the wooden boards 16 are fixedly connected with air bags 17.

[0033] As a technical optimization solution of the present utility model, by providing the wooden board 16, the contact area between the floating board 8 and the water surface is increased by the wooden board 16, thereby improving the floating effect of the floating board 8. By further providing the air bag 17, the buoyancy of the air bag 17 can assist in improving the floating effect of the floating board 8 and prevent the friction between the floating board 8 and the limiting rod 102 from affecting the floating effect of the floating board 8.

[0034] Reference Figure 4 , both the left side of the top and the bottom of the floating board 8 are fixedly connected with counterweight rings 18, and the material of the counterweight rings 18 is stainless steel.

[0035] As a technical optimization solution of the present utility model, by providing the counterweight rings 18, the weight of the floating board 8 can be assisted to increase by the counterweight rings 18, avoiding the situation that the floating board 8 is not stable enough during use and cannot be used continuously. By utilizing the advantage of stainless steel being oxidation-resistant, the service life of the counterweight rings 18 is improved.

[0036] Working principle and usage process of the present utility model: During the process of the user using the water tank 1 to replenish water to the foundation pit, the floating plate 8 can continuously float on the water surface in the water tank 1. When the water in the water tank 1 is continuously drained and used, the water surface in the water tank 1 will drop, causing the floating plate 8 to drop. Then, when the floating plate 8 drives the convex block 9 to contact the contact sensor 6 at the bottom, the contact sensor 6 will send an electrical signal through the control box 7 to turn on the water pump 3. Then, the water pump 3 will pump water into the water tank 1, causing the water in the water tank 1 to gradually increase and the water surface to gradually rise. Then, the floating plate 8 will rise synchronously with the water surface. When the convex block 9 on the floating plate 8 contacts the contact sensor 6 at the top, the contact sensor 6 will send an electrical signal through the control box 7 to turn off the water pump 3, thereby stopping the water injection into the water tank 1. During the process of the floating plate 8 being pushed by the water surface, the sliding fit between the limiting rod 102 and the limiting groove 101 can limit the floating plate 8 in the front, back, left, and right directions, preventing the floating plate 8 from shifting its current orientation during the up and down movement, resulting in the convex block 9 on the floating plate 8 being unable to contact the contact sensor 6. By using the sliding connection between the anti-rotation block 104 and the anti-rotation groove 103, the floating plate 8 is rotationally limited, preventing the floating plate 8 from rotating and causing the convex block 9 on the floating plate 8 to be unable to contact the contact sensor 6. During the use of the contact sensor 6, if the contact sensor 6 is damaged, the user can directly move the contact sensor 6, causing the plugging post 111 to no longer be plugged into the plugging slot 112. Then, the inlay ring 114 will disengage from the inlay groove 113, and then the contact sensor 6 can be replaced, facilitating the quick replacement of the contact sensor 6 and having the ability to automatically replenish water to the water tank 1.

[0037] In summary: For this automatic water replenishing device for the foundation pit water replenishing well, by setting the floating plate 8, when the floating plate 8 contacts the contact sensor 6 at the bottom, the water pump 3 is turned on to pump water into the water tank 1 for water replenishment. When the convex block 9 on the floating plate 8 contacts the contact sensor 6 at the top, the water pump 3 is turned off, solving the problem that the user still needs to manually observe the scale tube on the water tank to understand whether the water in the current water tank is sufficient, and then the user manually goes to turn on the water pump to replenish water to the water tank, and it cannot automatically replenish water to the water tank.
