Technical Field
[0001] The present application relates to the field of drainage systems, and in particular to an anti-clogging foundation pit drainage system for water conservancy and hydropower. Background Art
[0002] Foundation pit drainage refers to the preparatory work done when the groundwater level is higher than the excavation bottom surface during foundation pit excavation, and the groundwater will continuously seep into the pit to ensure that the foundation pit can be constructed under dry conditions, to prevent slope instability, foundation sand flow, pit bottom uplift, pit bottom pipe gushing and a decrease in foundation bearing capacity.
[0003] When existing water pumps are used to pump out water from large-area soil or water-logged foundation pits with complex terrain, conventional tubular water pumps or filter pipes will slow down the drainage speed due to the limitations of their water inlets or their traditional filter screens.
[0004] The inventors believe that the following defects exist: since the accumulated water in the foundation pit often contains impurities such as mud and sand, the presence of these impurities will cause damage to pumping equipment such as water pumps, and when pumping and draining water from a large area of stains or a water-logged foundation pit with complex terrain, it is impossible to achieve a convenient, efficient and anti-blocking effect, so there is room for improvement. Utility Model Content
[0005] In order to improve the damage caused by impurities such as mud and sand to water pumps and other pumping equipment; and to solve the problem that it is difficult to achieve convenient, efficient and anti-clogging effects when pumping and draining water from large-area stains or water-logged foundation pits with complex terrain, the present application provides an anti-clogging foundation pit drainage system for water conservancy and hydropower.
[0006] The present application provides an anti-clogging foundation pit drainage system for water conservancy and hydropower, which adopts the following technical solutions:
[0007] A water conservancy and hydropower anti-clogging foundation pit drainage system, comprising a cart placed on the ground, and a filtering device and a pumping device installed on the upper end surface of the cart; the cart comprises a horizontal plate, universal wheels installed at the four corners of the lower end surface of the horizontal plate, and a push rod fixed to one side of the horizontal plate; the filtering device comprises a shell with an opening on the lower end surface and a first filter screen connected to the shell opening with a sealing cover, and air bags are arranged around the four inner walls of the shell, and the air bags are fitted and fixed to the first filter screen; the pumping device comprises a water pump fixed to the upper end surface of the horizontal plate, and a first hose and a drainage hose sealed and plugged with the water pump; a plurality of battery packs for driving the water pump are fixed on the upper end surface of the horizontal plate, and a water pump switch for controlling the start and stop of the water pump is installed on the push rod; a circular hole is vertically penetrated through the upper end surface of the shell, and one end of the first hose away from the water pump is sealed and plugged into the circular hole.
[0008] By adopting the above technical scheme, when encountering large-area stains or water accumulation in foundation pits with less impurities, the conventional tubular water pump or filter pipe will slow down the drainage speed due to the limitations of its water inlet or its filter net, thereby affecting the construction speed; in view of the problems existing in the prior art, the present application proposes an anti-clogging foundation pit drainage system for water conservancy and hydropower. The filter device connected by the first hose in this embodiment is directly placed in the accumulated water, and the air bag will make the entire filter device float in the upper middle part of the large water-logged foundation pit, and because the larger sand and gravel sink to the bottom of the foundation pit, at this time, the air bag will make the ... Under the buoyancy of the bladder, combined with the pumping function of the water pump and the filtering function of the first filter net, a large amount of water is pumped out through the filtering device electrically connected to the water pump, which can not only increase the drainage speed but also effectively exclude impurities. Therefore, in the face of more complex terrain or deeper foundation pits, the first hose can be adjusted to a longer or shorter length to deal with these situations encountered; in terms of cost, both the outer filter steel net and the inner filter nylon net are relatively cheap, and the filtering effect on fine particles of dirt is better, which can effectively improve the efficiency of pumping out accumulated water in the foundation pit.
[0009] Preferably, the water pump is seal-connected with a second hose, the second hose is a retractable bellows structure, and a sealing cover at the pipe opening of one end of the second hose away from the water pump is connected to a second filter.
[0010] By adopting the above technical solution, when faced with complex terrain or a narrow foundation pit entrance, it is inconvenient to place the filtering device therein. The provision of the second hose allows the retractable hose to be inserted therein to solve the problem of pumping and draining water from the water-logged foundation pit.
[0011] Preferably, the first filter screen is a double-layer structure, the first filter screen comprises an outer first steel screen and an inner first nylon screen; the second filter screen comprises an outer second steel screen and an inner second nylon screen.
[0012] By adopting the above technical solution, the outer first steel mesh and the second steel mesh support the inner nylon mesh and protect the inner nylon mesh, effectively alleviating the impact and wear of larger sand and stones on the inner nylon mesh, and fully ensuring the functional operation of the inner nylon mesh.
[0013] Preferably, the diameter of the second hose is smaller than the diameter of the first hose.
[0014] By adopting the above technical solution, when faced with more complex terrain or a narrow entrance to the foundation pit, the filter device is not convenient to place therein. The second hose can solve the problem of pumping out water from the water-logged foundation pit by extending a retractable hose with a smaller diameter, thereby improving the efficiency of pumping out water from the foundation pit by operators.
[0015] Preferably, a storage rack is fixed to the upper end surface of the cart, and the storage rack includes four groups of short rods vertically fixed to the upper end surface of the horizontal plate and a fixing plate fixed to the upper end surface of each group of short rods; the water pump is fixed to the horizontal upper end surface of the fixing plate, and the battery pack is placed on the lower end surface of the fixing plate.
[0016] By adopting the above technical solution, in the case of rugged terrain, uneven road surface and poor geological environment, the setting of the cart facilitates the overall movement of the filtering device and the exhaust device by the operators, and improves the convenience of the operators' operation process; the setting of the storage rack increases the storage space of the cart, and the various groups of water pipes and battery packs are distributed up and down, which reduces the probability of the battery pack being soaked by water leakage from the water pipes, and improves the operation safety of the system.
[0017] Preferably, four groups of angle steels distributed opposite to each other are fixed to the upper end surface of the horizontal plate, and the filtering device is snap-fitted and fixed in each group of the angle steels.
[0018] By adopting the above technical solution, the filter device is clamped and fixed in each group of angle steels, which limits the displacement of the filter device and improves the stability of the filter device when the cart moves.
[0019] Preferably, a plurality of handles are fixed to the upper end surface of the shell.
[0020] By adopting the above technical solution, when faced with a situation where the filter device is needed, the provision of the handle facilitates the operator to carry the filter device, thereby improving the convenience of the operator in carrying the filter device.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. When encountering a large area of stains or water accumulation in a foundation pit with less impurities, the conventional tubular water pump or filter pipe will slow down the drainage speed due to the limitations of its water inlet or its filter screen, thereby affecting the construction speed. In view of the problems existing in the prior art, the present application proposes an anti-clogging foundation pit drainage system for water conservancy and hydropower. The filter device connected by the first hose in this embodiment is directly placed in the accumulated water. The airbag will make the entire filter device float in the upper middle part of the large water-logged foundation pit. Since the larger sand and stones sink to the bottom of the foundation pit, the buoyancy of the airbag will cause the filter device to float in the upper middle part of the large water-logged foundation pit. Under the action of combining the pumping function of the water pump and the filtering function of the first filter net, a large amount of water is pumped out through the filtering device electrically connected to the water pump, which can not only increase the drainage speed, but also effectively exclude impurities. Therefore, in the face of more complex terrain or deeper foundation pits, the first hose can be adjusted to a longer or shorter length to deal with these situations encountered; in terms of cost, both the outer filter steel net and the inner filter nylon net are relatively cheap, and the filtering effect on fine particles of dirt is better, which can effectively improve the efficiency of pumping out accumulated water in the foundation pit.
[0023] 2. When faced with more complex terrain or a narrow entrance to the foundation pit, it is not convenient to place the filter device therein. The second hose realizes the use of a retractable hose with a smaller diameter to extend into the pit to solve the problem of pumping water from the accumulated water in the foundation pit, thereby improving the efficiency of pumping water from the foundation pit for operators. The outer first steel mesh and the second steel mesh support the inner nylon mesh and also protect the inner nylon mesh, effectively alleviating the impact and wear of larger sand and stone on the inner nylon mesh, and fully ensuring the functional operation of the inner nylon mesh.
[0024] 3. In the face of rugged terrain, uneven roads, and poor geological environment, the setting of the cart facilitates the overall movement of the filtering device and the exhaust device by the operators, and improves the convenience of the operators' operation process; the setting of the shelf increases the storage space of the cart, and the various groups of water pipes and battery packs are distributed up and down, which reduces the probability of the battery pack being soaked by water leakage from the water pipes, and improves the operation safety of the system.
