Description

Technical Field

[0001] This utility model relates to the field of sandpit auxiliary devices, and in particular to a sandpit overflow and return device. Background Technology

[0002] With the increasing popularity of outdoor children's activities, outdoor sandpits have become a standard feature of children's activity areas. However, in actual use, sandpits present several problems, including sand scattering easily and being difficult to clean. The small particle size of the sand makes it easily blown away by the wind, and children inevitably bring sand out of the sandpit with their shoes and clothing during play. This causes the sand in the sandpit to deplete quickly, requiring regular replenishment. Sand also tends to accumulate on the ground around the sandpit, necessitating frequent cleaning.

[0003] To address the aforementioned problems, some improvements have been proposed in the prior art. For example, patent CN212235772U discloses a sand pit to prevent fine sand from overflowing. The sand pit has circular holes along its edge, each containing a spring. The edge of the sand pit is fitted with hinged, rotatable baffles. The lower ends of the springs extend into the circular holes, while their upper ends protrude from the holes and support the baffles.

[0004] While the improved sandpit can prevent the wind from blowing sand out of it, it still does not solve the problem of children carrying sand out of the sandpit through their shoes and clothing. Utility Model Content

[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1-4As shown, a sand pit overflow and return device includes a collection chamber 1 set at the edge of a sand pit 6. A sand leakage grid 2 is set at the top of the collection chamber 1, and a sand leakage guide plate 3 is set at the bottom of the collection chamber 1. A sand leakage box 4 is set at the end of the sand leakage guide plate 3 near the sand pit. The bottom plate 43 of both the sand leakage guide plate 3 and the sand leakage box 4 are inclined downwards towards the sand pit.

[0026] Collection chamber 1, as the main area for sand overflow recovery from the sand pit, serves to collect, store, and guide sand. Located at the edge of the sand pit 6, collection chamber 1 ensures that overflowing sand around the pit is collected promptly, preventing it from spilling outside the pit. The sand-leaking grid 2 allows people to walk through and lets sand flow from the sand pit 6 into the collection chamber, while also preventing larger debris or impurities from entering collection chamber 1. The design of the sand-leaking grid 2 ensures unobstructed sand recovery, preventing sand loss and filtering out some unwanted materials. The sand-leaking guide plate 3 guides sand from the sand-leaking grid 2 into the sand-leaking box 4. Due to the inclined design of the guide plate 3, the sand slides smoothly into the sand-leaking box 4 under the influence of gravity.

[0027] Furthermore, a filter screen 5 is provided between the sand-leaking grid 2 and the sand-leaking guide plate 3. The filter screen 5 can further remove impurities from the sand, ensuring that the sand entering the sand-leaking box 4 is cleaner. During the filtration process, the filter screen 5 can also prevent debris from entering the sand pit, thereby maintaining the quality and cleanliness of the sand in the sand pit. The setting of the filter screen 5 enhances the sand recycling effect and avoids the sand in the sand pit from being contaminated.

[0028] Furthermore, the collection chamber 1 includes a steel plate outer frame 11, and C-shaped channel steel 12 is fixedly arranged on both sides of the top of the collection chamber 1. The C-shaped channel steel 12 includes an upper top plate 121, a lower bottom plate 122 and a vertical connecting plate 123. The sand leakage grid 2 is installed on the upper end of the upper top plate 121 of the C-shaped channel steel 12 on both sides.

[0029] Furthermore, the filter screen 5 is installed on the upper end of the bottom plate 122 of the C-shaped channel steel 12 on both sides.

[0030] Furthermore, the sand-leaking box 4 has an opening on the side near the sand pit, and a sand-discharging grate 41 is hinged to the upper end of the opening. The sand-discharging grate 41 has multiple vertical sand-discharging grooves 42 evenly spaced along its length. The sand-discharging grate 41 allows sand to automatically pass through to the sand pit 6. When there is little sand, it can pass through the sand-discharging grooves 42; when there is a lot of sand, it can automatically push open the sand-discharging grate 41 to leak directly. When blocked, the hinged sand-discharging grate 41 can be manually opened to clean the sand-leaking box 4.

[0031] Furthermore, the bottom plate 43 of the sand-leaking box 4 is slidably connected to the two side walls of the sand-leaking box 4. When blocked, the bottom plate 43 can be manually pulled out to clean the sand-leaking box 4, providing an alternative cleaning method besides opening the hinged sand grate 41.

[0032] The C-shaped channel steel 12 serves as a supporting structure, enhancing the stability and structural strength of the collection chamber. The upper top plate 121 provides a fixed position for the sand-leaking grid 2, while the lower bottom plate 122 supports the installation of the filter screen 5. The vertical connecting plate 123 ensures the stability of the overall structure, making the entire device less prone to loosening or deformation during use.

[0033] Furthermore, the end of the sand-leaking guide plate 3 away from the sand pit is hinged to the side wall of the collection chamber 1, and the collection chamber 1 is provided with a diagonal brace plate 13 for supporting the sand-leaking guide plate 3 at the end of the sand-leaking guide plate 3 near the sand pit.

[0034] Furthermore, the inclined brace 13 is parallel to the sand guide plate 3 and uses surface support, which makes the structure more stable.

[0035] This sand pit overflow and return device, through its meticulously designed structural components, ensures that sand is not easily lost and can be effectively recycled and returned to the sand pit. The design of components such as the sand-leaking grid 2, filter screen 5, sand-leaking guide plate 3, and sand-leaking box 4 guarantees a smooth and efficient sand recycling process, while also removing impurities and maintaining the cleanliness and quality of the sand. The supporting structures, including the diagonal brace 13 and C-shaped channel steel 12, further enhance the stability and durability of the device. This device provides an effective technical solution to the problem of sand loss in sand pits, reduces the difficulty of sand pit maintenance, and improves the user experience.

[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
