[0053] It can be understood that the aforementioned handle 200 can have the aforementioned gripping portion 210 and the connecting portion 220, the connecting portion 220 is connected to the gripping portion 210 and is movably connected with the aforementioned cover body 100, and in the aforementioned second working state, the connecting portion 220 can be located outside the accommodating groove 103 or at least partially located in the accommodating groove 103, and the specific setting can be combined with actual needs, and is not limited here. The aforementioned gripping portion 210 can be cylindrical structure, the axial direction of the gripping portion 210 is substantially parallel to the extension direction of the first end surface 101, the diameter of the gripping portion 210 is greater than or equal to 5 mm and less than or equal to 10 mm, and the diameter of the gripping portion 210 can be set according to actual needs, and is not limited here.

[0054] It can be understood that the aforementioned handle 200 can be movable relative to the aforementioned cover body 100 within a stroke range, that is, the aforementioned handle 200 can be movable between the first limit position and the second limit position, and in the case that the handle 200 is located at the aforementioned first limit position, the cover body 100 is limited to cooperate with the handle 200, so that the cover body 100 can limit the handle 200 to move further away from the second limit position, and correspondingly, in the case that the handle 200 is located at the aforementioned second limit position, the cover body 100 is limited to cooperate with the handle 200, so that the cover body 100 can limit the handle 200 to move further away from the first limit position; in actual application, the first limit position can be matched with the first working state of the handle 200, and the second limit position can be matched with the second working state of the handle 200, so as to stably place the handle 200 in the accommodating groove 103 or keep it in the second working state.

[0055] It can be understood that the first end face 101 is provided with the accommodation groove 103, that is, at least one slot of the accommodation groove 103 is located on the first end face 101. In actual application, the accommodation groove 103 can be a groove penetrating through the first end face 101 and the second end face 102, that is, the accommodation groove 103 can be a groove without a bottom, or the groove bottom of the accommodation groove 103 can be located between the first end face 101 and the second end face 102, or protrude from the second end face 102. The specific setting can be combined with the actual demand, which is not limited here.

[0056] It can be understood that the cap of the fire hydrant is usually threadedly connected to the hydrant body, so that in actual application, the opening and closing state of the cap can be adjusted by rotating the cap. Accordingly, the operation member 300 can be an operation tool suitable for achieving circumferential limiting cooperation with the cap when connected to the cap. For example, the operation member 300 can be, but is not limited to, an operation tool such as a wrench, a pipe wrench, or a cap key specially used for opening and closing the cap. Exemplarily, the operation member 300 can have a matching part 320 for connecting the cap. When the matching part 320 is connected to the cap, the matching part 320 is in circumferential limiting cooperation with the cap. The shape parameters of the part of the matching part 320 for connecting the cap can be set in a targeted manner in combination with the shape parameters of the cap, so as to ensure the adaptability between the matching part 320 and the cap, or the shape parameters of the part of the matching part 320 for connecting the cap can be adjusted, so as to improve the versatility of the matching part 320.

[0057] It can be understood that the number of handles 200 and accommodation grooves 103 can be two, and the handle 200 and the accommodation groove 103 correspond one by one.

[0058] As shown in Figures 2 to 7 In some examples, the operation member 300 includes a handle part 310, a matching part 320 for connecting the cap, the cap being threadedly connected to the hydrant body, the matching part 320 being in circumferential limiting cooperation with the cap when the matching part 320 is connected to the cap, and a connecting rod part 330, the handle part 310 and the matching part 320 being respectively arranged at two ends of the connecting rod part 330. The connecting rod part 330 is detachably arranged on the second end face 102.

[0059] In the technical scheme, the operation piece 300 can include the handle portion 310, the fitting portion 320, and the connecting rod portion 330. Based on the foregoing arrangement, the operation piece 300 can be circumferentially limited and matched with the cap of the fire hydrant by the fitting portion 320, and the handle portion 310 can be used by the operator to operate the operation piece 300, so that the operator can apply force to the operation piece 300 through the handle portion 310, and then rotate the cap connected with the fitting portion 320. Based on the arrangement of the connecting rod portion 330, the force arm of the torque applied by the operation piece 300 to the cap can be increased, so that the physical effort of the operator in rotating the cap can be reduced, and the rapid opening and closing of the cap can be facilitated. In addition, the operation piece 300 can be connected to the second end surface 102 through the connecting rod portion 330. Since the connecting rod portion 330 is located at the middle position of the operation piece 300, the balance of the operation piece 300 can be improved when the operation piece 300 is arranged on the second end surface 102, the risk of the operation piece 300 falling off the second end surface 102 can be reduced, and the structural reliability of the well lid device can be improved.

[0060] It can be understood that the circumferential limiting and matching refers to that the fitting portion 320 is limited and matched with the cap in the rotation direction of the cap thread, so that the fitting portion 320 can be synchronously rotated with the cap. For example, a columnar protrusion with a polygonal cross section is usually formed on the cap, the axial direction of the columnar protrusion is consistent with the axial direction of the cap thread, and correspondingly, the fitting portion 320 can be formed with a columnar groove with a polygonal cross section matched with the columnar protrusion, so that the columnar protrusion is inserted into the columnar groove, and the circumferential limiting and matching between the fitting portion 320 and the cap is achieved. The outer peripheral wall shape of the fitting portion can be arranged according to actual needs. For example, the outer peripheral wall of the fitting portion can be a cylindrical wall.

[0061] It can be understood that, as shown in Figures 2 to 7 The connecting rod portion 330 and the fitting portion 320 can be coaxially arranged, and the axial direction of the fitting portion 320 can be the axial direction of the columnar groove. The extension direction of the handle portion 310 and the axial direction of the connecting rod portion 330 can intersect.

[0062] In some examples, the connecting rod portion 330 is a telescopic structure, so that the distance between the handle portion 310 and the fitting portion 320 can be adjusted. The connecting rod portion 330 has a third working state and a fourth working state. In the third working state, the distance between the handle portion 310 and the fitting portion 320 is less than the diameter of the cover body 100. In the fourth working state, the distance between the handle portion 310 and the fitting portion 320 is greater than the diameter of the cover body 100.

[0063] In the technical scheme, the connecting rod part 330 can be a telescopic structure, and the cover body 100 can be a circular cover plate; based on the above arrangement, on the one hand, the connecting rod part 330 can be arranged on the second end surface 102 when in the third working state, so as to avoid the operation member 300 protruding from the circumferential side of the cover body 100, and facilitate the connecting rod part 330 to be hidden and stored in the fire well through the well mouth when covering the well mouth; on the other hand, the connecting rod part 330 can increase the distance between the handle part 310 and the matching part 320 when in the fourth working state, so as to further lengthen the force arm of the torque exerted by the operation member 300 on the cover, and reduce the physical exertion of the operator when screwing the cover.

[0064] As shown in Figures 5 to 7 some examples, the connecting rod part 330 includes: a pipe body 331, the matching part 320 being arranged at one end of the pipe body 331; a rod body 332, the rod body 332 being arranged in the pipe body 331, one end of the rod body 332 away from the matching part 320 being connected to the handle part 310 and located outside the pipe body 331, the rod body 332 being adapted to move along the axial direction of the pipe body 331; and a limiting assembly 333, the limiting assembly 333 being arranged on the rod body 332, the limiting assembly 333 having a limiting state and an unlocking state; in the limiting state, the limiting assembly 333 limits the movement of the rod body 332; in the unlocking state, the rod body 332 can move along the axial direction of the pipe body 331.

[0065] In the technical scheme, the connecting rod part 330 can include the pipe body 331, the rod body 332 and the limiting assembly 333; based on the above arrangement, on the one hand, the connecting rod part 330 can have telescopic ability while having a relatively simple structure, so as to reduce the manufacturing cost of the connecting rod part 330 and facilitate the compactness of the structure of the connecting rod part 330; on the other hand, the connecting rod part 330 can limit or release the relative movement between the rod body 332 and the pipe body 331 by means of the limiting assembly 333, and accordingly, when the limiting assembly 333 limits the relative movement between the rod body 332 and the pipe body 331, the relative position between the pipe body 331 and the rod body 332 can be ensured to be stable, so as to improve the structural stability of the operation member 300, thereby facilitating the operator to screw the cover by means of the operation member 300, and when the limiting assembly 333 releases the relative movement between the rod body 332 and the pipe body 331, the relative movement between the pipe body 331 and the rod body 332 can be facilitated, so as to realize the telescoping of the connecting rod part 330.

[0066] In some feasible examples, the rod body 332 is hollow inside, so as to reduce the weight of the rod body 332 and further facilitate the operator to use the operation member 300.

[0067] As shown in Figure 7As shown, in some examples, the limiting assembly 333 comprises a positioning pin 3331 having a connecting end and a fitting end, the peripheral side of the rod body 332 is provided with a mounting hole, the positioning pin 3331 is arranged through the mounting hole and is in sliding fit between the mounting hole and the positioning pin 3331, and the connecting end is located in the mounting hole; an elastic member 3332 is connected between the rod body 332 and the connecting end, and is used for applying a force to the positioning pin 3331 in the direction from the connecting end to the fitting end; wherein the peripheral side of the tube body 331 is provided with at least two positioning holes, the at least two positioning holes are arranged at intervals along the axial direction of the tube body 331, and the fitting end is adapted to extend into or exit the positioning hole.

[0068] In the technical scheme, the limiting assembly 333 comprises the aforementioned positioning pin 3331 and the aforementioned elastic member 3332; based on the foregoing arrangement, in the case that the positioning pin 3331 extends into the aforementioned positioning hole, the limiting assembly 333 is in the aforementioned limiting state, the movement of the rod body 332 is limited, and the positioning pin 3331 can be relatively stably kept in the positioning hole under the action of the force applied by the elastic member 3332, so as to ensure the relative position stability between the tube body 331 and the rod body 332, improve the structural stability of the operating member 300, and facilitate the operation personnel to rotate the cap through the operating member 300; in actual application, the positioning pin 3331 can be caused to overcome the force applied by the elastic member 3332 and exit the positioning hole by applying a force opposite to the force output by the elastic member 3332 to the positioning pin 3331 in the positioning hole, and correspondingly, in the case that the positioning pin 3331 exits the aforementioned positioning hole, the limiting assembly 333 is in the aforementioned unlocking state, the movement limitation of the rod body 332 is removed, and the rod body 332 can move along the axial direction of the tube body 331, so as to facilitate the relative movement between the tube body 331 and the rod body 332, so as to realize the extension and contraction of the connecting rod part 330.

[0069] It can be understood that the aforementioned at least two positioning holes can comprise at least a first positioning hole and a second positioning hole; wherein along the axial direction of the tube body 331, the maximum distance between the first positioning hole and the fitting part 320 is a first distance, the maximum distance between the second positioning hole and the fitting part 320 is a second distance; along the axial direction of the rod body 332, the maximum distance between the positioning pin 3331 and the handle part 310 is a third distance; the sum of the aforementioned first distance and the aforementioned third distance is less than the diameter of the cap body 100, and the sum of the aforementioned second distance and the aforementioned third distance is greater than the diameter of the cap body 100. Based on the foregoing arrangement, in the case that the positioning pin 3331 is located in the first positioning hole, the connecting rod part 330 is in the aforementioned third working state, and correspondingly, in the case that the positioning pin 3331 is located in the second positioning hole, the connecting rod part 330 is in the aforementioned fourth working state.

[0070] In some examples, the tube body 331 and the rod body 332 are circumferentially limited and matched.

[0071] In the technical scheme, the pipe body 331 and the rod body 332 can be circumferentially limited and matched; based on the foregoing arrangement, the pipe body 331 and the rod body 332 can be synchronously rotated, so that the operator can apply a torque to the cover through the operation part, so as to realize the opening and closing adjustment of the cover.

[0072] In some examples, the cross section of the inner space of the pipe body 331 is polygonal, and the cross section of the rod body 332 is polygonal, and the shape of the cross section of the inner space is matched with the shape of the cross section of the rod body 332.

[0073] In the technical scheme, the cross section shapes of the inner space and the rod body 332 are constrained; based on the foregoing arrangement, the pipe body 331 and the rod body 332 can be circumferentially limited and matched, so that the operator can apply a torque to the cover through the operation part, so as to realize the opening and closing adjustment of the cover.

[0074] Exemplarily, the pipe body 331 and the rod body 332 can both be square tubes, so that the pipe body 331 and the rod body 332 can be made of profiles, reducing the manufacturing cost of the pipe body 331 and the rod body 332, and the weight of the rod body 332 can be reduced.

[0075] It can be understood that the shape of the cross section of the inner space is matched with the shape of the cross section of the rod body 332, that is, the outer contour shape parameters of the cross section of the inner space and the cross section of the rod body 332 are substantially the same.

[0076] As shown in Figures 2 to 4 In some examples, the outdoor fire well cover device further comprises a fixing member 400 formed with a clamping groove, and the fixing member 400 is arranged on the second end surface 102, and the operation member 300 is detachably clamped on the fixing member 400.

[0077] In the technical scheme, the outdoor fire well cover device can further comprise the fixing member 400; based on the foregoing arrangement, the operation member 300 can be disassembled on the second end surface 102 by cooperating with the fixing member 400, and correspondingly, when the operation member 300 is clamped on the fixing member 400, the position stability of the operation member 300 can be ensured, the operation member 300 can be fixed and placed relative to the cover body 100, and the risk of damage or loss of the operation member 300 can be reduced.
