[0039] In the prior art, underground well chamber diversion troughs are generally constructed by masonry, which has the disadvantages of low construction efficiency, high risk of working in confined spaces, and high requirements for masonry quality.

[0040] In view of this, the designer provides an underground well chamber diversion device, which is easy to assemble, flexible to use, long service life and low cost.

[0041] Please combine Figure 1 In this embodiment, the underground well chamber diversion device includes a diversion seat 100, a filter screen 200, a diversion baffle 300 and a slag collecting box 400; the diversion seat 100 is provided with a diversion groove 101, the diversion groove 101 has a first end 110 and a second end 120 in its extension direction, the filter screen 200 is installed on the diversion seat 100 and closes the second end 120; the diversion baffle 300 is installed in the diversion groove 101; the slag collecting box 400 is installed in the diversion groove 101 and is connected to the diversion groove 101, and is used to collect impurities carried in the liquid flowing in the diversion groove 101.

[0042] Based on the above, the working principle of the underground well chamber diversion device provided in this embodiment is as follows:

[0043] The guide seat 100 is installed at the set position of the well chamber, and the size of the guide seat 100 is designed according to the on-site environment for easy installation. After the guide seat 100 is installed, the water flows from the first end to the second end in the guide groove 101. During the flow, the water contacts the guide baffle 300. The guide baffle 300 slows down the water flow and can reduce the potential energy of the water flow. At the same time, since the water flows slowly in the guide groove 101, impurities are easily deposited in the slag box 400. Figure 1 Taking the middle perspective as an example, water flows from left to right. During the flow, the water first passes through the guide baffle 300 and then flows through the filter 200. When flowing through the filter 200, the impact on the filter 200 is small, and the filter 200 is not easily damaged by the impact, and has a long service life.

[0044] The following embodiments illustrate the details of the underground well chamber diversion device of the present application by way of examples.

[0045] Please combine Figure 1 and Figure 2 In this embodiment, the cross-sectional profile of the guide groove 101 is optionally arc-shaped, and the cross-sectional profile is a plane perpendicular to the extension direction of the guide groove 101. With such a design, after the water flows into the guide groove 101, the groove wall of the guide groove 101 has a diversion function, so that impurities can move from the groove wall of the guide groove 101 to the groove bottom wall, so that the impurities are deposited in the slag collecting box 400, which is conducive to the collection of impurities.

[0046] For example, in this embodiment, the cross-sectional profile of the guide groove 101 is semicircular.

[0047] It should be noted that the number of the guide baffles 300 can be multiple, and the multiple guide baffles 300 are arranged at intervals in the width direction of the guide groove 101. For example, in this embodiment, the number of the guide baffles 300 is two, and the two guide baffles 300 are arranged symmetrically. Since the number of the guide baffles 300 is multiple, the guide groove 101 can be divided into multiple subspaces, and the probability of water flow contacting the guide baffles 300 when flowing in the guide groove 101 increases, which can reduce the potential energy of the water flow, slow down the flow speed of the water flow, facilitate the deposition and collection of impurities, and also reduce the impact of the water flow on the filter 200, and the filter 200 has a long service life.

[0048] Furthermore, the thickness of the guide baffle 300 gradually decreases in the direction from the first end 110 to the second end 120, and the thickness direction of the guide baffle 300 is consistent with the width direction of the guide groove 101. With such a design, the guide baffle 300 is a gradual structure, and when impurities carried in the water flow flow to the side of the guide baffle 300 with a smaller width, the impurities are not easily accumulated on the side of the guide baffle 300, which is conducive to the impurities being deposited in the slag collecting box 400.

[0049] Please combine Figure 1 and Figure 3 In this embodiment, optionally, a threaded hole is provided on the end surface of the guide seat 100 corresponding to the second end 120, and the filter screen 200 includes a frame 210 and a mesh body 220 connected to the frame 210. A fastener 230 is provided on the frame 210, and the fastener 230 is screwed into the threaded hole so that the mesh body 220 closes the second end 120. It should be understood that the number of threaded holes can be multiple, and the multiple threaded holes are evenly spaced and arranged, and a fastener 230 can be provided in each threaded hole. The fastener 230 can be, but is not limited to, a screw or the like. The mesh body 220 is fixed to the guide seat 100 by the frame 210, and the frame 210 is firmly combined with the guide seat 100, which facilitates the installation and removal of the mesh body 220.

[0050] Furthermore, a sealing strip 240 is provided between the frame 210 and the guide seat 100. By providing the sealing strip 240, the sealing between the frame 210 and the guide seat 100 can be increased, and the water flow needs to pass through the mesh body 220 during the flow process to play a filtering role.

[0051] Furthermore, at least one of the frame 210 and the guide seat 100 is provided with a positioning groove, and the sealing strip 240 is embedded in the positioning groove. The sealing strip 240 is arranged in the positioning groove, and the position of the sealing strip 240 is accurate and not easy to fall off, so the sealing effect is good and the service life is long.

[0052] It should be understood that the sealing strip 240 can be a semicircular strip, and the extended shape of the positioning groove can also be a semicircular shape, which is conducive to the cooperation between the sealing strip 240 and the positioning groove. In addition, the threaded holes can be distributed on both sides of the positioning groove, so that the amount of compression of the sealing strip 240 is uniform and the sealing effect is good. The positioning groove can be provided on the frame 210, or on the side of the guide seat 100, or both the frame 210 and the guide seat 100 can be provided with positioning grooves.

[0053] In addition, in other embodiments, the frame 210 can be directly bonded and fixed to the side surface of the guide seat 100 .

[0054] In other embodiments, optionally, a mounting groove 102 is provided on the bottom wall of the guide groove 101, and the slag collecting box 400 is detachably connected to the mounting groove 102. With such a design, the slag collecting box 400 is arranged in the mounting groove 102, the height of the slag collecting box 400 is low, and the top of the slag collecting box 400 does not protrude from the bottom wall of the guide groove 101, which is conducive to slag collection.

[0055] In this embodiment, optionally, a buckle 410 is provided on the side of the slag collecting box 400 close to the first end 110 , and the slag collecting box 400 can leave the installation groove 102 when the buckle 410 is in an unlocked state.

[0056] It should be understood that by operating the buckle 410, when the buckle 410 is in an unlocked state, the slag collecting box 400 can be separated from the guide seat 100, so that the slag collecting box 400 can be removed and cleaned easily after being removed.

[0057] In this embodiment, optionally, a fixing through hole 103 for a bolt to pass through is provided on the guide seat 100. After the bolt passes through the fixing through hole 103, the guide seat 100 is fixed to the set position of the well chamber by the bolt, and the guide seat 100 is firmly positioned and not easily displaced during use. It should be understood that the fixing through holes 103 are provided on both opposite sides of the guide seat 100, and the fixing effect of the guide seat 100 is good, and the position is firmly and reliably.

[0058] The underground well chamber flow diversion device provided in this embodiment has a simple structure, is easy to assemble, is flexible to use, and has a long service life.
