TECHNICAL FIELD
[0001] The utility model relates to a water-logging sewage filtering device, concretely relates to a water-logging sewage filtering device in water power station equipment foundation pit. BACKGROUND
[0002] The water power station equipment foundation pit is usually arranged outdoors without the support structure, or the equipment itself is the unit facility that stores water or utilizes water energy to operate, therefore, the water-logging environment often exists in the foundation pit, and the mud and other impurities are accompanied.
[0003] In view that the water-logging cannot stay in the foundation pit for a long time, 1-2 drainage holes are often arranged at the lower part of the foundation pit bottom, so that the water-logging is conveniently drained, but a large amount of water-logging is accompanied by the mud, and the drainage pipeline is blocked for a long time, so that a large amount of manpower and material resources need to be spent for the subsequent pipeline dredging. SUMMARY
[0004] In view of the defects existing in the arrangement of the existing drainage technology, the utility model provides a water-logging sewage filtering device in water power station equipment foundation pit, which can effectively solve the above problems.
[0005] The technical scheme adopted by the utility model is as follows: a water-logging sewage filtering device in water power station equipment foundation pit, which comprises a water-logging sewage filtering device, a device clamping groove and a clamping groove fixing bolt; the water-logging sewage filtering device is a stainless steel fish scale structure mesh with a gap, the water-logging sewage filtering device is installed in the device clamping groove in the way of a bolt, and the device clamping groove is fixed on the inner wall and the bottom surface of the equipment foundation pit by the clamping groove fixing bolt.
[0006] The arrangement number of the water-logging sewage filtering device is 1, and the water-logging sewage filtering device is arranged at the position close to the drainage pipe in the water power station equipment foundation pit.
[0007] The stainless steel fish scale structure mesh is the convex of the fish scale structure punched out of the stainless steel plate, and the free end of the convex of the fish scale structure forms a gap, so that the mesh with one end in an open state is formed.
[0008] The utility model has the advantages of reasonable structure, safe use, easy construction, convenient replacement, wide applicability and quick installation, can effectively avoid that the impurity mud in the water-logging of the equipment foundation pit blocks the drainage pipeline, reduces the cleaning cost of the pipeline dredging, and can be widely applied to the water-logging environment that needs to filter the impurities and reduce the temporary maintenance.

[0013] In order to make the utility model's purpose, technical scheme and advantage more clear and clear, the following is with the drawing, and the utility model is further detailed.The specific embodiment described here is merely used to explain the utility model and is not used to limit the utility model.
[0014] In the description of the utility model, it needs to be explained that the orientation or position relation indicated by the terms "upper", "middle", "lower", "inner", "outer", "two sides" and the like is based on the orientation or position relation shown in the drawing, and is merely for the convenience of the simplified description of the utility model, and is not indicated or implied that the indicated device or element must have a particular orientation, a particular orientation configuration and operation, so it can not be understood as the limitation of the utility model.
[0015] In the description of the utility model, it needs to be explained that unless another explicit provision and limitation, the terms "installation", "set with", "connection" and the like should be understood broadly, for example "connection", can be fixed connection, can also be detachable connection, or integrally connected;Can be mechanical connection, can also be electrical connection;Can be directly connected, can also be indirectly connected through intermediate medium, can be the intercommunication of two elements.For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0016] As Figures 1-2 The utility model discloses a water and electricity station equipment foundation pit inner accumulated water sewage filtering device, including accumulated water sewage filtering device 1, device clamping groove 2, clamping groove fixed bolt 3;Accumulated water sewage filtering device 1 is the stainless steel scale structure screen 1.1 with gap, and accumulated water sewage filtering device 1 is installed in device clamping groove 2 through the way of latch, and device clamping groove 2 is fixed in the equipment foundation pit inner wall and bottom surface with clamping groove fixed bolt 3.
[0017] As Figure 3 The accumulated water sewage filtering device 1 is arranged at the position close to the drain pipe in the water and electricity station equipment foundation pit, and the number of the accumulated water sewage filtering device 1 is one.
[0018] The stainless steel fish scale structure mesh 1.1 is a fish scale structure protrusion punched out of a stainless steel plate, and the free end of the fish scale structure protrusion forms a gap, thereby forming a mesh with one end in an open state.
[0019] Specifically, the accumulated water drainage and filtration device 1 comprises a stainless steel fish scale structure mesh 1.1, each fish scale has protrusions arranged up and down, and cavities are arranged between the fish scales to drain the sewage and filter and adsorb the impurities and sludge in the water on the stainless steel fish scale structure mesh 1.1; the device clamping groove 2 is an installation accessory of the stainless steel fish scale drainage and filtration device 1, the clamping groove is fixed on the inner wall and bottom surface of the equipment foundation pit by bolts 3, the stainless steel fish scale drainage and filtration device 1 can be installed on the clamping groove 2 in a way of inserting a pin, and can be disassembled and cleaned after the impurities and sludge are adsorbed; the clamping groove fixing bolt 3 is a common bolt, which can fix the device clamping groove 2 on the inner wall and bottom surface of the equipment foundation pit.
