Description

Technical Field

[0001] The present application relates to the technical field of manhole covers, and in particular to a water vapor separator manhole cover. Background Art

[0002] The water vapor separator is used to be installed on the horizontal pipeline. The water vapor separator is a device used to separate gas and liquid in water vapor. Its working principle is mainly based on the principle of physics. When the steam and water enter the separation chamber of the separator, the flow rate of the steam and water slows down. Due to the small density of the gas, it floats to the top of the separation chamber, while the liquid sinks to the bottom of the separation chamber. Finally, the gas in the separator will be discharged and the liquid will be collected, thus realizing the separation of gas and liquid.

[0003] The manhole covers in the prior art were originally designed to be movable and do not have too many limiting structures. When the water vapor separator is installed underground and the exhaust pressure reaches more than 10 kilograms, the inspection wells near the water vapor separator are under high pressure, and there is a possibility that the manhole covers will suddenly open due to pressure, posing certain safety hazards to passing vehicles and personnel on the road, and therefore further improvements are needed. Utility Model Content

[0004] In order to reduce the possibility of the manhole cover suddenly opening due to pressure, the present application provides a water vapor separator manhole cover.

[0005] The water vapor separator manhole cover provided in this application adopts the following technical solution:

[0006] A water vapor separator manhole cover comprises a manhole seat and a manhole cover, wherein the manhole seat is used to be installed at the wellhead of an inspection well, one side of the manhole cover is hinged to the manhole seat, an air vent is provided on the surface of the manhole cover, a limiting member is provided between the manhole cover and the manhole seat, and the limiting member is used to slow down the opening and closing speed of the manhole cover.

[0007] By adopting the above-mentioned technical solution and setting the limiter, the manhole cover is normally closed on the manhole seat. When the air pressure is low, the gas can be discharged outward through the air vents to relieve the pressure. When the exhaust pressure exceeds the range value (above 10 kg), the manhole cover opens slowly under the action of the limiter, reducing the possibility of the manhole cover opening suddenly due to pressure, thereby reducing the safety hazards of vehicles and personnel passing by on the road.

[0008] Optionally, the limiting member includes a gas rod, one end of which is hinged to the inner wall of the well seat, and the other end of which is hinged to the lower surface of the well cover, and the gas rod normally closes the well cover to the well seat.

[0009] By adopting the above-mentioned technical solution and setting a gas rod, one end of the gas rod is hinged to the inner wall of the well seat, and the other end is hinged to the lower surface of the well cover to ensure that the well cover can be opened to release pressure; the cylinder can slow down the opening speed of the well cover, thereby reducing the possibility of the well cover being suddenly opened due to pressure.

[0010] Optionally, a plurality of elastic pull strips are provided on the inner wall of the well seat, one end of the elastic pull strip away from the well seat is connected to the free side of the manhole cover, and the well seat is provided with a winding piece for winding up the elastic pull strips.

[0011] By adopting the above-mentioned technical solution, through the arrangement of elastic pull strips and winding pieces, when the manhole cover is in the closed state, the winding piece winds up the elastic pull strips, and when the manhole cover is opened under pressure, the elastic pull strips exert a pulling force on the free side of the manhole cover, thereby further slowing down the opening speed of the manhole cover; when the manhole cover is in the open state, multiple elastic pull strips are blocked between the manhole cover and the well seat to reduce the possibility of people falling into the inspection well, thereby improving the safety of the overall structure.

[0012] Optionally, the winding member includes a rotating roller and a winding spring, the rotating roller is rotatably connected to the inner wall of the well seat, and the end of the elastic pull strip away from the well cover is used to be wound around the outer peripheral wall of the rotating roller; the winding spring is installed between the rotating roller and the well seat, and the winding spring normally causes the rotating roller to be wound around the elastic pull strip, and the well cover is closed on the well seat.

[0013] By adopting the above-mentioned technical scheme, through the setting of the rotating roller and the coil spring, the rotating roller reels the elastic pull strip under the action of the coil spring. When the manhole cover is opened, the elastic force of the elastic pull strip and the elastic force of the coil spring act on the manhole cover together to slow down the opening speed of the manhole cover; when the manhole cover is closed, the elastic force of the coil spring drives the rotating roller to rotate to reel in the elastic pull strip, thereby storing the elastic pull strip.

[0014] Optionally, an installation box is provided on the inner wall of the well seat, the rotating roller is rotatably connected in the installation box, the rotating roller is rotatably connected to the well seat through the installation box, and a connecting groove is opened on the side wall of the installation box for the elastic pull rod to pass through; a mounting piece is provided between the installation box and the well seat, and the installation box can be detachably mounted on the well seat through the mounting piece.

[0015] By adopting the above-mentioned technical solution and setting up the installation box and the installation parts, when the operator needs to open the manhole cover and enter the inspection well, the installation box is disassembled through the installation parts to separate the elastic pull rod from the well seat, thereby reducing the possibility of the elastic pull rod blocking the well seat and the manhole cover, so as to facilitate the operator to enter the inspection well.

[0016] Optionally, a first mounting hole is provided on the side wall of the mounting box, a second mounting hole is provided on the inner wall of the well seat, and the mounting member includes a mounting bolt, which is sequentially passed through the first mounting hole and the second mounting hole and is threadedly connected to the second mounting hole.

[0017] By adopting the above technical solution and by setting the mounting bolts, the mounting box can be disassembled and assembled by rotating the mounting bolts, thereby improving the convenience of disassembly and assembly of the mounting box.

[0018] Optionally, an embedding groove is provided on the inner wall of the well seat, and the installation box is embedded in the embedding groove; the installation component includes a rotating rod, a limit stop bar and a magnet, one end of the rotating rod is rotatably connected to the inner wall of the well seat, and the other end is fixedly connected to the limit stop bar, the limit stop bar is rotatably connected to the inner wall of the well seat through the rotating rod, and the limit stop bar is normally arranged vertically and blocked by the notch of the embedding groove; the magnet is embedded in the limit stop bar and is used to be magnetically attracted to the inner wall of the well seat.

[0019] By adopting the above technical scheme, through the setting of the rotating rod, the limit stop bar and the magnet, under normal conditions, the limit stop bar rotates to a vertical state and blocks the notch of the embedding groove, thereby blocking the installation box and keeping the installation box embedded in the embedding groove; when removing the installation box, the limit stop bar is turned to rotate so that the limit stop bar is disengaged from the notch of the embedding groove, and the installation box can be taken out, which greatly improves the convenience of disassembly and assembly between the installation box and the well seat; through the setting of the magnet, the limit stop bar is kept in a vertical state as much as possible to block the notch of the embedding groove, thereby improving the stability of the connection between the installation box and the well seat.

[0020] Optionally, a plurality of reflective marking layers are provided on the side wall of each of the elastic strips, and the plurality of reflective marking layers are arranged at intervals along the length direction of the elastic strip.

[0021] By adopting the above technical solution and setting the reflective identification layer, when the manhole cover is opened, the reflective identification strip has a striking effect, so that passing vehicles or people can pass through the opened manhole cover in time, thereby improving the safety of the overall structure.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the setting of the limiter, the manhole cover is normally closed at the manhole seat. When the air pressure is low, the gas can be discharged outward through the air vent to relieve the pressure; when the exhaust pressure exceeds the range value (more than 10 kg), the manhole cover will open slowly under the action of the limiter, reducing the possibility of the manhole cover opening suddenly due to pressure, thereby reducing the safety hazards of vehicles and personnel passing by the road;

[0024] 2. Through the setting of the elastic pull strip and the winding piece, when the manhole cover is in the closed state, the winding piece rolls up the elastic pull strip. When the manhole cover is opened under pressure, the elastic pull strip exerts a pulling force on the free side of the manhole cover, thereby further slowing down the opening speed of the manhole cover; when the manhole cover is in the open state, multiple elastic pull strips are blocked between the manhole cover and the well seat to reduce the possibility of people falling into the inspection well and improve the safety of the overall structure;

[0025] 3. Through the setting of the rotating rod, the limit stop bar and the magnet, under normal circumstances, the limit stop bar rotates to a vertical state and blocks the notch of the embedding groove, thereby blocking the installation box and keeping the installation box embedded in the embedding groove; when removing the installation box, the limit stop bar is turned to rotate so that the limit stop bar is disengaged from the notch of the embedding groove, and the installation box can be taken out, which greatly improves the convenience of disassembly and assembly between the installation box and the well seat; through the setting of the magnet, the limit stop bar is kept in a vertical state as much as possible to block the notch of the embedding groove, thereby improving the stability of the connection between the installation box and the well seat.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] Embodiment 1:

[0033] The embodiment of the present application discloses a water vapor separator manhole cover.

[0034] Reference Figure 1The water vapor separator manhole cover comprises a manhole seat 1 and a manhole cover 2. In the present embodiment, the manhole seat 1 is used to be installed at the wellhead of the inspection well. The manhole seat 1 is arranged as a rectangular ring structure, and the manhole cover 2 is arranged as a rectangular plate structure. One side of the manhole cover 2 is hinged to the inner wall of the manhole seat 1. It should be noted that a plurality of heavy-duty hinges 8 are installed between one side of the manhole cover 2 and the inner wall of the manhole seat 1 (the hinges 8 are the structure of the prior art, and the structure thereof will not be elaborated on in detail herein), and one side of the manhole cover 2 is hinged to the manhole cover 2 through a plurality of hinges 8.

[0035] Reference Figure 1 A plurality of air holes 21 are provided on the surface of the manhole cover 2, and each of the air holes 21 is a through hole penetrating the manhole cover 2. The air holes 21 are used for exhausting air to relieve the pressure of the inspection well. It should be noted that when the manhole cover 2 needs to be opened manually, the air holes 21 can be used for docking with tools such as hooks, so that the operator can hook up the manhole cover 2.

[0036] Reference Figure 1 A limiting member is installed between the manhole cover 2 and the manhole seat 1, and the limiting member is used to slow down the opening and closing speed of the manhole cover 2; the limiting member is set as a gas rod 3, and the number of gas rods 3 can be one or more. In the present embodiment, the number of gas rods 3 is set to two, one end of the gas rod 3 is hinged to the inner wall of the manhole seat 1, and the other end is hinged to the lower surface of the manhole cover 2. The gas rod 3 normally closes the manhole cover 2 to the manhole seat 1.

[0037] The implementation principle of Example 1 of the present application is: when the exhaust pressure in the inspection well exceeds the range value (above 10 kilograms), the manhole cover 2 is pushed open under pressure. At this time, the cylinder pulls on the manhole cover 2, which can slow down the opening speed of the manhole cover 2, thereby reducing the possibility of the manhole cover 2 being suddenly opened due to high pressure.

[0038] Embodiment 2:

[0039] The embodiment of the present application discloses a water vapor separator manhole cover.

[0040] Reference Figure 2 , Figure 3 The difference between the water vapor separator manhole cover disclosed in the embodiment of the present application and embodiment 1 is that:

[0041] In this embodiment, an installation box 6 is installed on the inner wall of the well seat 1, and a first installation strip 63 is fixedly installed on the bottom wall of the installation box 6. A first installation hole 62 penetrating the first installation strip 63 is provided on the side wall of the first installation strip 63. A second installation hole 11 is provided on the inner wall of the well seat 1. The second installation hole 11 is arranged opposite to the first installation hole 62. A mounting member 7 is installed between the installation box 6 and the inner wall of the well seat 1. The mounting member 7 is configured as a mounting bolt 71. The mounting bolt 71 is sequentially passed through the first mounting hole 62 and the second mounting hole 11 and is threadedly connected to the second mounting hole 11. The installation box 6 can be detachably mounted on the inner wall of the well seat 1 by the mounting bolt 71.

[0042] Reference Figure 2 , Figure 3 The mounting box 6 is a hollow long strip box structure, and a connecting groove 61 is provided on the side wall of the mounting box 6 away from the second mounting hole 11, and the connecting groove 61 is connected to the inside of the mounting box 6, and both ends of the connecting groove 61 are extended along the length direction of the mounting box 6; for the convenience of description, the side of the manhole cover 2 away from the hinge hinge 8 is defined as the free side of the manhole cover 2, and a second mounting strip 22 is fixedly installed on the free side of the manhole cover 2, and both ends of the second mounting strip 22 are extended along the length direction of the mounting box 6, and the second mounting strip 22 is detachably mounted on the lower surface of the free side of the manhole cover 2 by bolt fixing.

[0043] Reference Figure 2 , Figure 3 A plurality of elastic pull strips 4 are installed between the installation box 6 and the second installation strip 22. The elastic pull strips 4 are elastically arranged and are arranged at intervals along the length direction of the second installation strip 22. One end of the elastic pull strip 4 is fixedly connected to the side wall of the second installation strip 22, and the other end passes through the interior of the installation box 6 through the connecting groove 61. A winding piece for winding up the elastic pull strip 4 is installed in the installation box 6.

[0044] Reference Figure 3 In this embodiment, the winding member includes a rotating roller 5 and a winding spring. The rotating roller 5 is rotatably installed in the installation box 6. The rotating roller 5 is rotatably installed in the well seat 1 through the installation box 6. The axial direction of the rotating roller 5 is consistent with the length direction of the installation box 6. The end of the elastic pull strip 4 away from the well cover 2 (that is, the end of the elastic pull strip 4 away from the second installation strip 22) is inserted into the installation box 6 and fixedly connected with the outer peripheral wall of the rotating roller 5, driving the rotating roller 5 to rotate, so that the elastic pull strip 4 can be wound around the outer peripheral wall of the rotating roller 5 to reel the elastic pull strip 4.

[0045] The coil spring is installed between the rotating roller 5 and the inner wall of the installation box 6 (the coil spring is a prior art structure, its structure will not be elaborated here, and it is not shown in the figure). The coil spring normally causes the rotating roller 5 to be rolled up on the elastic pull strip 4, and the manhole cover 2 is closed on the manhole seat 1.

[0046] Reference Figure 2 , Figure 3 In this embodiment, a plurality of reflective marking layers 41 are installed on the side wall of each elastic strip 4. The reflective marking layers 41 have a reflective and eye-catching effect. The plurality of reflective marking layers 41 are arranged at intervals along the length direction of the elastic strip 4. The reflective marking layers 41 can be made of reflective paint. The reflective coating is applied to the side wall of the elastic strip 4. After the reflective paint solidifies, the reflective marking layers 41 are formed.

[0047] The implementation principle of Example 2 of the present application is as follows: through the setting of the elastic pull strip 4, on the one hand, when the manhole cover 2 is pressed to open outward, the elastic force of the elastic pull strip 4 and the elastic force of the coil spring act on the manhole cover 2, which can further slow down the opening speed of the manhole cover 2, thereby reducing the possibility of the manhole cover 2 being suddenly opened due to pressure, thereby reducing the safety hazard of vehicles and personnel passing by on the road; on the other hand, after the manhole cover 2 is opened, multiple elastic pull strips 4 block between the manhole cover 2 and the well seat 1, reducing the possibility of people stepping on air and falling into the inspection well; on the other hand, the reflective identification layer 41 of the elastic pull strip 4 can have a striking effect, so that people can promptly find the manhole cover 2 in the open state, thereby improving the safety of the overall structure.

[0048] When the operator needs to enter the inspection well for work, the installation box 6 can be disassembled by loosening the installation bolts 71, so that the elastic pull bar 4 can be separated from the well seat 1, so as to facilitate the entry of the operator and improve the operational convenience of the overall structure.

[0049] Embodiment 3:

[0050] The embodiment of the present application discloses a water vapor separator manhole cover.

[0051] Reference Figure 4 The difference between the water vapor separator manhole cover disclosed in the embodiment of the present application and embodiment 2 is that:

[0052] An embedding groove 12 is provided on the inner wall of the well seat 1 away from the hinge 8, and the two ends of the embedding groove 12 are extended along the length direction of the second mounting strip 22. The embedding groove 12 is used for matching and embedding the mounting box 6. In this embodiment, a plurality of mounting members 7 are provided and are arranged at intervals along the length direction of the mounting box 6; each mounting member 7 includes a rotating rod 72, a limit stop strip 73 and a magnet 74, one end of the rotating rod 72 is rotatably connected to the inner wall of the well seat 1, and the other end is fixedly connected to the limit stop strip 73, and the rotating rod 72 is located at the bottom of the embedding groove 12.

[0053] The limit stop bar 73 is in the shape of a long strip, and the side wall of the limit stop bar 73 close to the rotating rod 72 is abutted against the inner wall of the well seat 1 away from the hinge hinge 8. The limit stop bar 73 is rotatably connected to the inner wall of the well seat 1 through the rotating rod 72, and under the action of its own gravity, the length direction of the limit stop bar 73 is normally set vertically, so that the limit stop bar 73 partially blocks the notch of the embedding groove 12. When the length direction of the limit stop bar 73 is rotated to a horizontal state, the limit stop bar 73 is separated from the notch of the embedding groove 12; the magnet 74 is embedded in the side wall of the limit stop bar 73 close to the rotating rod 72, and the magnet 74 is used to be magnetically attracted to the inner wall of the well seat 1, so that the upper end of the limit stop bar 73 remains blocked by the notch of the embedding groove 12.

[0054] The implementation principle of Example 3 of the present application is as follows: when installing the installation box 6, rotate the limit stop bar 73 so that the length direction of the limit stop bar 73 is rotated to a horizontal state, and then the installation box 6 is embedded in the embedding groove 12, and then the limit stop bar 73 is rotated so that the limit stop bar 73 is blocked at the notch of the embedding groove 12, so as to limit the installation box 6 in the embedding groove 12, thereby greatly improving the convenience of disassembly and assembly of the installation box 6.
