Description

Technical Field

[0001] The present application relates to the technical field of manhole covers, and in particular, to a manhole cover that is easy to remove. Background Art

[0002] Sewers, underground gas pipes, water pipes, power pipes, communication pipes, national defense pipes and other underground pipes must have an outlet leading to the ground at intervals. The section from the pipe to the ground is called a manhole. The manhole opening is usually flush with the ground, so a manhole cover is needed to cover it.

[0003] At present, existing manhole covers are usually made of reinforced cement, metal, reinforced plastic and other materials, mainly in round and square shapes, and embedded in the ground to block the manhole opening. However, since manholes are often heavy, subsequent staff often need to lift them up with great effort before they can open and remove the manhole cover.

[0004] There is no manhole cover that is convenient to take out now. Utility Model Content

[0005] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a manhole cover that is easy to remove, including a base, a mounting ring is fixed to the edge of the upper port of the base, and the mounting ring is matched with the manhole cover, and the upper end surface of the mounting ring is symmetrically provided with two sections of clamping grooves along the circumferential edge of the base, and the clamping groove includes an inclined groove portion and a flat groove portion, the bottom surface of the inclined groove portion is a slope inclined toward the bottom of the base, the bottom surface of the flat groove portion is horizontal, and two clamping wheels are symmetrically fixed to the circumferential edge of the lower end surface of the manhole cover, and the clamping wheels are rolled in the clamping groove and roll along the inclined groove portion into the flat groove portion.

[0007] As a further preferred embodiment, at least two buckle grooves are symmetrically provided on the upper end surface of the manhole cover.

[0008] As a further preferred embodiment, a plurality of drain ports connected to the bottom are provided in the middle of the upper end surface of the manhole cover, a drain cylinder connected to the drain ports is constructed on the lower end surface of the manhole cover, and the drain cylinder is inserted into the base as the manhole cover covers the base.

[0009] As a further preferred solution, the middle portion of the inner wall of the water discharge cylinder bulges inwards to form a water collecting port, and a filter is elastically installed in the water collecting port.

[0010] As a further preferred solution, the filter element includes a filter arc plate that blocks the lower port of the water collecting port, and a sewage collecting trough is fixed around the edge of the filter arc plate.

[0011] As a further preferred solution, a fixing plate is horizontally fixed in the middle of the lower port of the water discharge cylinder, a mounting tube is fixed on the upper end surface of the fixing plate, a movable shaft is elastically inserted in the mounting tube, and the top end of the movable shaft is supported in the middle of the lower end surface of the filter arc plate.

[0012] As a further preferred solution, a limit plate is fixed on a section of the movable shaft placed in the installation tube, and a spring supporting the limit plate on the movable shaft is installed in the installation tube.

[0013] As a further preferred solution, the lower end of the movable shaft passes through the lower end surface of the fixed plate.

[0014] The beneficial effect of the present application is that it provides a manhole cover that is easy to remove. Thanks to the cooperation between the snap-in groove on the base and the snap-in wheel at the bottom of the manhole cover, rotating the manhole cover on the base can cause the snap-in wheel to roll along the inclined groove portion into the flat groove portion, thereby lifting the manhole cover from the upper end of the base. There is no need for staff to use tools such as crowbars to pry it open laboriously, so that staff can quickly open and remove the manhole cover, which is easy to use.

[0015] At the same time, the manhole cover is also provided with a water cylinder on the lower end face of the manhole cover, and the water collecting port in the water cylinder cooperates with the filter element to utilize the filter arc plate to filter the sewage entering the base and the inside of the water cylinder. As the debris in the sewage accumulates on the filter arc plate, the elastic support under the filter element will be overcome to make the filter element sink, so that the debris can slide along the curved surface of the filter arc plate to the sewage collecting trough at the edge of the filter arc plate for collection, thereby ensuring that the middle part of the filter arc plate can still perform good sewage filtration treatment and the filtering effect is good.

[0025] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0026] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0027] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0028] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0029] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] Reference Figure 1 , Figure 2 and Figure 3As shown, a manhole cover that is easy to remove includes a base 1, a mounting ring 101 is fixed to the edge of the upper port of the base 1, and the upper end surface of the mounting ring 101 is symmetrically provided with two sections of snap-in grooves 3 along the circumferential edge of the base 1, and the snap-in groove 3 includes an inclined groove portion 301 and a flat groove portion 302, the bottom surface of the inclined groove portion 301 is a slope inclined toward the bottom of the base 1, and the bottom surface of the flat groove portion 302 is horizontal.

[0031] The mounting ring 101 is equipped with a manhole cover 2, and two snap-in wheels 4 are symmetrically fixed to the circumferential edge of the lower end surface of the manhole cover 2. The snap-in wheels 4 are rolled in the snap-in groove 3 and roll along the inclined groove portion 301 into the flat groove portion 302. Two buckle grooves 201 are symmetrically provided on the upper end surface of the manhole cover 2, so that the staff can rotate the manhole cover 2 to make the snap-in wheels 4 roll along the inclined groove portion 301 into the flat groove portion 302. As the level of the bottom of the inclined groove portion 301 to the flat groove portion 302 rises, the snap-in wheels 4 will prop up the manhole cover 2 from the upper end of the base 1, thereby eliminating the need for the staff to pry it open with tools such as crowbars, so that the staff can quickly open and remove the manhole cover 2, which is convenient to use.

[0032] Reference Figure 3 and Figure 4 As shown, a plurality of drain ports 5 connected to the bottom are provided in the middle of the upper end surface of the manhole cover 2, and a drain cylinder 6 connected to the drain ports 5 is constructed on the lower end surface of the manhole cover 2, and the drain cylinder 6 is inserted into the base 1 as the manhole cover 2 covers the base 1, so that the manhole cover 2 can be discharged through the drain ports 5 and the drain cylinder 6.

[0033] like Figure 4 As shown, the middle part of the inner wall of the water collecting cylinder 6 is convex inwards to form a water collecting port 7, and a filter 8 is elastically installed in the water collecting port 7, so that the sewage entering the water collecting cylinder 6 will be collected at the filter 8. The filter 8 includes a filter arc plate 801 that blocks the lower end of the water collecting port 7, and a sewage collecting tank 802 is fixed around the edge of the filter arc plate 801.

[0034] At the same time, a fixing plate 9 is horizontally fixed in the middle of the lower port of the water discharge cylinder 6, and a mounting tube 10 is fixed to the upper end surface of the fixing plate 9. A movable shaft 11 is elastically inserted in the mounting tube 10, and the top end of the movable shaft 11 is supported in the middle of the lower end surface of the filter arc plate 801. In this embodiment, the movable shaft 11 is placed on a section of the installation tube 10 to fix a limit plate, and a spring 1001 is installed in the installation tube 10 to support the limit plate of the movable shaft 11, so that the filter arc plate 801 is elastically installed on the lower port of the water gathering port 7. Therefore, the filter arc plate 801 is used to filter the sewage entering the base 1 and the sewer cylinder 6. As the debris in the sewage accumulates on the filter arc plate 801, it will overcome the elastic support under the filter element 8 to make the filter element 8 sink, so that the debris can slide along the curved surface of the filter arc plate 801 to the sewage collecting trough 802 at the edge of the filter arc plate 801 for collection, thereby ensuring that the middle part of the filter arc plate 801 can still perform good sewage filtration treatment and have a good filtering effect.

[0035] In addition, the lower end of the movable shaft 11 passes through the lower end surface of the fixed plate 9, so that after the base 1 is taken out, the filter element 8 can be pulled down by the lower end of the movable shaft 11 to facilitate pulling the sewage collection tank 802 out of the water cylinder 6 to facilitate cleaning of dirt.

[0036] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
