[0002] In today's era when environmental protection has attracted much attention, sewage pit interception devices, as important equipment in the field of environmental protection, have a pivotal position in maintaining ecological balance due to their performance and effect. Traditional sewage pit interception devices mostly adopt a fixed interception net design. Although this design can intercept larger dirt to a certain extent, its filtering effect is slightly insufficient when facing fine particles. In addition, this fixed interception net design, due to its fixed form, the gap of the interception net is fixed, making it impossible to adjust the gap size, so it is impossible to intercept dirt of different sizes. Utility Model Content

[0003] The utility model aims to overcome the problems that the existing sewage pit sewage interception device adopts a fixed interception net, has a poor filtering effect on fine particles, cannot adjust the gap size, and cannot intercept sewage of different sizes. The utility model aims to provide a sewage pit sewage interception device that can solve the above problems.

[0004] A sewage pit sewage interception device includes a first interception net and a second interception net arranged on the downstream side of the first interception net, the first interception net and the second interception net are both arranged horizontally in the sewage pit water inlet channel, and the gap between the first interception net and the second interception net is a diamond structure of the same size. A first fixed platform is arranged below the first interception net, the first fixed platform is fixed to the bottom of the sewage pit water inlet channel, and the top surface of the first fixed platform is connected to the bottom surface of the first interception net. A first lifting platform is arranged below the second interception net, the first lifting platform is arranged at the bottom of the sewage pit water inlet channel, and the top surface of the first lifting platform is connected to the bottom surface of the second interception net. A first limiting slide is vertically fixed to the inner side of the side wall of the sewage pit water inlet channel, and the two side edges of the first interception net and the second interception net are arranged in the first limiting slide.

[0005] Furthermore, the first limiting sliding groove has two grooves arranged vertically side by side, and the two side edges of the first interception net and the second interception net are respectively arranged in the two grooves.

[0006] Furthermore, when the height of the first lifting platform is at its lowest, the first lifting platform is at the same height as the first fixed platform, and the gaps between the first interception net and the second interception net overlap.

[0007] Furthermore, it also includes a first filter net, which is arranged on the downstream side of the second interception net, and the first filter net is arranged at an interval with the second interception net.

[0008] Furthermore, it also includes a second filter screen arranged on the downstream side of the first filter screen, a second lifting platform is arranged below the second filter screen, a second fixed platform is arranged below the first filter screen, and second limiting slide grooves are arranged on both sides of the first filter screen and the second filter screen.

[0009] Furthermore, the second limiting sliding groove is provided with two grooves vertically side by side, and the two side edges of the first filter screen and the second filter screen are respectively arranged in the two grooves.

[0010] Furthermore, the first lifting platform and the second lifting platform both include a connecting plate and a lifting bag, the lifting bag is fixed to the bottom surface of the connecting plate, a hydraulic pump station is provided on the top of the side wall of the sewage pit water inlet channel, and the hydraulic pump station is connected to the lifting bag through a hydraulic oil pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The sewage pit sewage intercepting device in the utility model is provided with a first interception net and a second interception net with the same gap size and both of which are diamond-shaped structures. The first interception net is installed at the bottom of the sewage pit water inlet channel, and a first lifting platform is arranged at the bottom of the second interception net, so that the height of the second interception net can be adjusted. When the first interception net and the second interception net are at the same height, the gaps between the two interception nets are overlapping.

The principle of providing the second filter net is the same as that of the second interception net, and the pore size formed by the first filter net and the second filter net can be adjusted by changing the height of the second filter net to filter particles of different particle sizes.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] like Figure 1 , Figure 2 as well as Figure 3As shown, the sewage pit sewage intercepting device in this embodiment includes a first interception net 1 and a second interception net 3 arranged on the downstream side of the first interception net 1. The first interception net 1 and the second interception net 3 are both arranged horizontally in the sewage pit water inlet channel 2, and the gap between the first interception net 1 and the second interception net 3 is a diamond structure of the same size. A first fixed platform 4 is arranged below the first interception net 1, and the first fixed platform 4 is fixed to the bottom of the sewage pit water inlet channel 2, and the top surface of the first fixed platform 4 is connected to the bottom surface of the first interception net 1. A first lifting platform 5 is arranged below the second interception net 3, and the first lifting platform 5 is arranged at the bottom of the sewage pit water inlet channel 2, and the top surface of the first lifting platform 5 is connected to the bottom surface of the second interception net 3.

[0026] A first limiting chute 6 is vertically fixed to the inner side of the side wall of the sewage pit water inlet channel 2, and the two side edges of the first interception net 1 and the second interception net 3 are arranged in the first limiting chute 6. Specifically, the first limiting chute 6 is vertically arranged with two channels side by side, and the width of the channel is adapted to the width of the edges of the first interception net 1 and the second interception net 3, and the two side edges of the first interception net 1 and the second interception net 3 are respectively arranged in the two channels. Preferably, the first interception net 1 and the second interception net 3 are both composed of a frame and an interception net body, and the frame is arranged in the channel.

[0027] In this embodiment, when the first lifting platform 5 is at the lowest height, the first lifting platform 5 is at the same height as the first fixed platform 4, and the gaps between the first interception net 1 and the second interception net 3 overlap. At this time, the gap formed by the two interception nets is larger, so that larger impurities can be intercepted. When the second interception net 3 rises, the gaps between the two interception nets will be staggered, resulting in a smaller gap between the two interception nets, thereby intercepting smaller impurities, making up for the defect that a single fixed interception net cannot adjust the gap size. Specifically, the top surface of the first lifting platform 5 is in contact with the bottom surface of the second interception net 3, and the top surface of the first fixed platform 4 is in contact with the bottom surface of the first interception net 1.

[0028] The sewage pit intercepting device in this embodiment also includes a first filter screen 7 and a second filter screen 8 arranged on the downstream side of the first filter screen 7. The first filter screen 7 is arranged on the downstream side of the second intercepting net 3, and the first filter screen 7 and the second intercepting net 3 are arranged at intervals, so that a temporary storage space for waste is formed between the second intercepting net 3 and the first filter screen 7 to prevent the accumulation of waste filtered by the first filter screen 7 and cause blockage. The pore sizes of the first filter screen 7 and the second filter screen 8 are the same and both have a circular structure, and the pore sizes of the first filter screen 7 and the second filter screen 8 are smaller than the gap sizes of the first intercepting net 1 and the second intercepting net 3.

[0029] In this embodiment, a second fixed platform 10 is provided below the first filter screen 7, a second lifting platform 9 is provided below the second filter screen 8, and second limiting chutes 19 are provided on both sides of the first filter screen 7 and the second filter screen 8. The two second limiting chutes 19 are relatively and vertically fixed on the inner side of the side wall of the sewage pit water inlet channel 2, and the first limiting chute 6 is vertically provided with two grooves side by side, and the width of the grooves is adapted to the width of the edges of the first filter screen 7 and the second filter screen 8, and the edges of the first filter screen 7 and the second filter screen 8 are respectively provided in the two grooves. Preferably, the first filter screen 7 and the second filter screen 8 are both composed of a frame and an interception net body, and the frame is provided in the groove.

[0030] In this embodiment, when the second lifting platform 9 is at its lowest height, the second lifting platform 9 is at the same height as the second fixed platform 10, and the apertures of the first filter 7 and the second filter 8 overlap. At this time, the apertures formed by the two filter screens are the largest, thereby being able to intercept fine particles with larger particle sizes. When the second filter screen 8 is raised, the apertures of the two filter screens will be staggered, causing the apertures formed by the two filter screens to become smaller, thereby intercepting fine particles with smaller particle sizes. Specifically, the top surface of the second lifting platform 9 is in contact with the bottom surface of the second filter screen 8, and the top surface of the second fixed platform 10 is in contact with the bottom surface of the first filter screen 7.

[0031] Specifically, in this embodiment, the first lifting platform 5 and the second lifting platform 9 both include a connecting plate and a lifting bag, the lifting bag is fixed to the bottom surface of the connecting plate, and a hydraulic pump station 11 is arranged on the top of the side wall of the sewage pit water inlet channel 2. The hydraulic pump station 11 is connected to the two lifting bags respectively through two independently controlled hydraulic oil pipes. The lifting bags are rubber bags, and the rubber bags have a longitudinal corrugated structure. When the hydraulic pump station 11 pressurizes and injects hydraulic oil into the lifting bags, the height of the lifting bags is increased, and the depressurized hydraulic oil returns to the hydraulic pump station 11, so that the height of the lifting bags is reduced, thereby changing the height of the first lifting platform 5 and the second lifting platform 9.

[0032] In this embodiment, the top surfaces of the first interception net 1, the second interception net 3, the first filter net 7 and the second filter net 8 are all provided with lifting ears 12, so as to facilitate lifting and installation.

[0033] Embodiment 2:

[0034] like Figure 4 As shown, the sewage pit intercepting device in this embodiment also includes a lifting mechanism. The lifting mechanism includes a door frame 13 and a winch 14. The door frame 13 is movably arranged on the top surface of the side wall of the sewage pit water inlet channel, and the winch 14 is installed on the top surface of the door frame 13. The end of the lifting rope of the winch 14 is connected to a hook connected to the lifting ear 12.

[0035] Specifically, a slide rail 15 is provided on the top surface of the side wall of the sewage pit water inlet channel, and two sets of front and rear track wheels 16 adapted to the track are provided at the bottom of both sides of the door frame 13, and the track wheel 16 is provided with a braking structure (not shown in the figure), so that it can move forward and backward along the slide rail 15 on the side wall of the sewage pit water inlet channel, thereby hoisting and installing the first interception net 1, the second interception net 3, the first filter net 7 and the second filter net 8.

[0036] In order to further ensure the stability of the lifting mechanism, an L-shaped support arm 17 is provided on the side of the bottom of the gate frame 13 away from the sewage pit water inlet channel. The L-shaped support arm 17 is inverted and the upper end is fixedly connected to the bottom of the gate frame 13, and the lower end is close to the sewage pit water inlet channel. A roller 18 that rolls on the outer side of the side wall of the sewage pit water inlet channel is provided.
