Description

Technical Field

[0001] This utility model relates to the field of subway construction technology, and in particular to a monitoring and protection device for deep foundation pits in subways. Background Technology

[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. Their construction has solved the problem of inconvenient transportation. During the initial construction phase, monitoring points need to be set up in deep foundation pits for effective monitoring of the pit's interior. To prevent damage to the monitoring equipment, protective devices are installed at these points, housing the monitoring equipment within these devices. However, existing protective devices for subway deep foundation pit monitoring points have at least the following drawbacks: 1. Typical protective devices cannot be adjusted in size, limiting their protection to a single monitoring device within the deep foundation pit; 2. Most subway deep foundation pit monitoring devices are integral, non-disassembly structures that cannot cool or dissipate heat from the internal monitoring equipment, thus requiring further improvement. Utility Model Content

[0003] The main purpose of this utility model is to provide a monitoring and protection device for deep foundation pits in subways, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A monitoring and protection device for deep foundation pits in subways includes a base plate. A rear limiting plate is fixedly connected to the upper rear part of the base plate. A shaped slot with an upper through-hole is opened in the middle of the front end of the rear limiting plate. A baffle is engaged in the shaped slot. An elliptical opening with left and right through-holes is opened at the left end of the baffle. A partition structure is provided in the elliptical opening. T-shaped limiting grooves with left and right through-holes are opened at both the upper front and upper rear parts of the base plate. An assembly heat dissipation structure is slidably connected in the two T-shaped limiting grooves. The two assembly heat dissipation structures are symmetrically distributed from left to right. The T-shaped limiting grooves are located between the two assembly heat dissipation structures.

[0006] Preferably, the partition structure includes a partition plate located inside the elliptical opening. The upper left end and the lower left end of the partition plate each have through holes that pass through from left to right, and each of the two through holes is provided with a snap-fit ​​component.

[0007] Preferably, the snap-fit ​​assembly includes a connecting post, and a fixing ring block is movably connected to the left and right outer surfaces of the connecting post, and an abutment block is fixedly connected to the upper outer surface of each of the two fixing ring blocks.

[0008] Preferably, the connecting column is fixedly connected to the partition plate through a through hole, and the two abutments engage the partition plate and the baffle plate together.

[0009] Preferably, the assembled heat dissipation structure includes a protective cabinet, with elongated sliders fixedly connected to the lower front and lower rear of the protective cabinet, a heat dissipation fan provided in the middle of the upper inner wall of the protective cabinet, and a cabinet door movably installed on the left front end of the protective cabinet.

[0010] Preferably, both of the elongated sliders are T-shaped, and the protective cabinet is slidably connected to the base plate via the two elongated sliders and the two T-shaped limiting grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting up a partition structure with two snap-fit ​​components, two connecting posts are inserted and fixedly connected to the partition. The left and right sides of the outer surfaces of the two connecting posts are movably connected with fixed ring blocks and abutment blocks. Therefore, with these coordinations, personnel can snap the partition into the through oval opening on the left end of the baffle. By rotating the abutment block, the partition and the baffle can be snapped together. Thus, it can adjust the size of the protective equipment placement area in the protective cabinet.

[0013] 2. By setting up an assembly heat dissipation structure, the protection cabinet is slidably connected to the base plate through two long sliders and two T-shaped limit grooves, which makes it easy for personnel to install the protection cabinet on which the equipment is placed.

[0023] A monitoring and protection device for deep foundation pits in subways includes a base plate 1. A rear limiting plate 2 is fixedly connected to the upper rear part of the base plate 1. A shaped slot 3 with an upper through-hole is opened in the middle of the front end of the rear limiting plate 2. A baffle 4 is engaged in the shaped slot 3. An elliptical opening 5 with left and right through-hole is opened at the left end of the baffle 4. A partition structure 6 is provided in the elliptical opening 5. A T-shaped limiting slide groove 7 with left and right through-hole is opened at both the upper front and upper rear parts of the base plate 1. An assembled heat dissipation structure 8 is slidably connected in the two T-shaped limiting slide grooves 7. The two assembled heat dissipation structures 8 are symmetrically distributed from left to right. The T-shaped limiting slide groove 7 is located between the two assembled heat dissipation structures 8.

[0024] In this embodiment, the partition structure 6 includes a partition plate 61 located inside the elliptical opening 5. The upper left and lower left ends of the partition plate 61 each have through holes 62, and each through hole 62 contains a snap-fit ​​component 63. The snap-fit ​​component 63 includes a connecting post 631. The left and right outer surfaces of the connecting post 631 are movably connected to fixing rings 632. The upper outer surfaces of the two fixing rings 632 are fixedly connected to abutments 633. The connecting post 631 is fixedly connected to the partition plate 61 through the through holes 62, and the two abutments 633 snap the partition plate 61 and the baffle 4 together. By providing the partition structure 6, which includes the partition plate 61, through holes 62, and snap-fit ​​components 63, and by using the two abutments 633 to snap the partition plate 61 and the baffle 4 together, the two protective cabinets 81 can be connected internally by disassembling the partition plate 61, thereby adjusting the size of the monitoring equipment placement area.

[0025] In this embodiment, the assembled heat dissipation structure 8 includes a protective cabinet 81. Long sliders 82 are fixedly connected to the lower front and lower rear of the protective cabinet 81. A cooling fan 85 is provided in the middle of the upper inner wall of the protective cabinet 81. A cabinet door 84 is movably installed on the left front end of the protective cabinet 81. Both long sliders 82 are T-shaped. The protective cabinet 81 is slidably connected to the base plate 1 via the two long sliders 82 and two T-shaped limiting grooves 7. By setting the assembled heat dissipation structure 8, the protective cabinet 81 is slidably connected to the base plate 1 via the two long sliders 82 and two T-shaped limiting grooves 7, so that the baffle 4 is located between the two protective cabinets 81, facilitating the assembly of the protective cabinet 81. Furthermore, the cooling fan 85 on the upper inner wall of the protective cabinet 81 can cool and dissipate heat for the monitoring equipment placed inside the protective cabinet 81.

[0026] It should be noted that this utility model is a monitoring and protection device for deep foundation pits in subways. During use, the upper rear part of the base plate 1 is first fixed to the rear limiting plate 2.

Then, two T-shaped limiting grooves 7 with left and right through-holes are opened on the upper end of the base plate 1. Personnel can slide two symmetrically distributed protection cabinets 81 into the two T-shaped limiting grooves 7 via two long sliders 82. This facilitates the assembly of the protection cabinets 81 of the foundation pit monitoring and protection equipment. Therefore, a cooling fan 85 is electrically connected via an external power cord. It can provide cooling and heat dissipation for the monitoring equipment inside the protection cabinet 81. In addition, the partition 61 is located in the oval opening 5 at the left end of the baffle 4.
