Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 As shown:

[0029] A monitoring and protection device for deep foundation pits in subways includes a T-shaped mounting base 101 and multiple sets of mounting holes 102 on the surface of the mounting base 101.

[0030] In this implementation plan: In order to solve the technical problems existing in the prior art, such as the background art disclosed above, "when the monitoring equipment is inspected and maintained, the cabinet may restrict the working space of the maintenance personnel, making the inspection and maintenance of the equipment more difficult. The compact space may make it difficult for the maintenance personnel to easily access the equipment, increasing the difficulty and complexity of maintenance." In combination, this problem is obviously a real and difficult problem to solve.

[0031] Furthermore:

[0032] like Figures 1-5 As shown:

[0033] Based on the above: A panel 103 for installing monitoring equipment is fixedly installed on one side of the mounting base 101;

[0034] A first housing cover 105 and a second housing cover 106 are respectively provided on the panel 103. Multiple sets of drawer slides 104 are installed between the panel 103 and the first housing cover 105 and the second housing cover 106 respectively. The first housing cover 105 and the second housing cover 106 can slide stably on the panel 103 through the drawer slides 104.

[0035] The mounting base 101 has slots on both sides for insertion into the first housing cover 105 and the second housing cover 106. When the first housing cover 105 and the second housing cover 106 are inserted into the slots of the mounting base 101, the sides of the first housing cover 105 and the second housing cover 106 are in contact with each other.

[0036] A cabinet door 107 is hinged to one side of the first housing cover 105, and the cabinet door 107 is used to seal the opening formed by the docking of the first housing cover 105 and the second housing cover 106.

[0037] A locking mechanism 2 is installed between the cabinet door 107 and the second housing cover 106. The locking mechanism 2 includes a connecting plate 201 fixed to one side of the cabinet door 107 and a locking pin 203 sliding between both ends of the connecting plate 201. A second spring 202 is fixed between the locking pin 203 and the connecting plate 201.

[0038] The upper and lower sides of the second housing cover 106 are fixed with strip plates 205. One end of the strip plate 205 is provided with a insertion hole 204 for the locking pin 203 to be inserted. Both ends of the connecting plate 201 are provided with sliding grooves that are adapted to the locking pin 203. The locking pin 203 and the connecting plate 201 are slidably connected through these sliding grooves.

[0039] In this implementation plan: the monitoring point protection device for the deep foundation pit of the subway can be installed on the surface of panel 103 for the monitoring equipment;

[0040] The surface of the mounting base 101 has multiple sets of mounting holes 102. Bolts (not shown in the figure) pass through the mounting holes 102 to install the mounting base 101 in a designated position, thereby installing the protective device.

[0041] When it is necessary to inspect and maintain the monitoring equipment installed on the panel 103, by pressing the two sets of locking pins 203 at the same time, the locking pins 203 compress the second spring 202 until the locking pins 203 are compressed into the connecting plate 201, so that the locking pins 203 disengage from the insertion hole 204 opened in the strip plate 205, thereby releasing the connection lock between the connecting plate 201 and the strip plate 205.

[0042] While the connecting plate 201 and the strip plate 205 are unlocked, the connection lock between the cabinet door 107 and the second housing cover 106 is also released.

[0043] At this time, the cabinet door 107 is opened, allowing the cabinet door 107 to rotate on the first housing cover 105 via the hinge, thereby releasing the blockage at the opening formed by the docking of the first housing cover 105 and the second housing cover 106.

[0044] Then, the first housing cover 105 and the second housing cover 106 are pulled to move away from each other, and the first housing cover 105 and the second housing cover 106 slide stably on the panel 103 via the drawer slide rail 104.

[0045] This solution optimizes the cabinet structure by expanding the maintenance space for staff through the unfolding of the first housing cover 105 and the second housing cover 106. This allows maintenance personnel to easily access the monitoring equipment to be inspected and maintained, thereby significantly improving the efficiency of equipment inspection and maintenance. The limitations of the compact space are effectively alleviated, maintenance time is reduced, and the difficulty and complexity of maintenance are lowered.

[0046] Furthermore;

[0047] In an optional embodiment, one end of the locking pin 203 has a locking hole 206.

[0048] In this embodiment: a combination lock can be installed on the lock hole 206. The combination lock can limit and lock the lock pin 203 on the strip plate 205, preventing other people from pressing the lock pin 203 to open the cabinet door 107, thus achieving the anti-theft effect.

[0049] Furthermore;

[0050] In an optional embodiment, top pins 110 are slidably attached to both ends of the top of panel 103, a first spring 109 is fixed between the top pins 110 and panel 103, and a baffle 111 is fixed to one side of the sidewalls of the first housing cover 105 and the second housing cover 106 that are close to each other.

[0051] A movable groove adapted to the top pin 110 is provided on one side of the panel 103. The top pin 110 and the panel 103 are slidably connected through this movable groove. A handle 108 is fixed on the surface of the cabinet door 107.

[0052] In this embodiment: when the first housing cover 105 and the second housing cover 106 move to both ends of the panel 103, the top pin 110 is pressed to compress the first spring 109, preventing the top end of the top pin 110 from contacting the lower surface of the baffle 111. When the first housing cover 105 and the second housing cover 106 move, the baffle 111 passes over the top pin 110. Then the top pin 110 is released, and the first spring 109 rebounds to drive the top pin 110 to move upward, thereby blocking the baffle 111. This achieves the limitation of the first housing cover 105 and the second housing cover 106, preventing personnel from being blown closer to each other by the wind during maintenance and repair, thus affecting the personnel's maintenance operations.

[0053] A handle 108 is provided on the surface of the cabinet door 107, which facilitates the opening of the cabinet door 107.

[0054] The working principle and usage process of this utility model: This subway deep foundation pit monitoring and measuring point protection device; when it is necessary to inspect and maintain the monitoring equipment installed on the panel 103, by simultaneously pressing the two sets of locking pins 203, the locking pins 203 compress the second spring 202 until the locking pins 203 are compressed into the connecting plate 201, so that the locking pins 203 disengage from the insertion hole 204 opened in the strip plate 205, thereby releasing the connection lock between the connecting plate 201 and the strip plate 205; at the same time as the connecting plate 201 and the strip plate 205 are released from lock, the connection lock between the cabinet door 107 and the second housing cover 106 is also released;

[0055] Next, hold handle 108 and open cabinet door 107. Cabinet door 107 rotates on first housing cover 105 via hinges, thereby releasing the seal at the opening formed by the docking of first housing cover 105 and second housing cover 106. Then, pull first housing cover 105 and second housing cover 106 to move away from each other. First housing cover 105 and second housing cover 106 slide stably on panel 103 via drawer slide rail 104.

[0056] When the first housing cover 105 and the second housing cover 106 move to the two ends of the panel 103, the top pin 110 is pressed, which compresses the first spring 109, preventing the top end of the top pin 110 from contacting the lower surface of the baffle 111. When the first housing cover 105 and the second housing cover 106 move, the baffle 111 passes over the top pin 110. Then the top pin 110 is released, and the first spring 109 rebounds, driving the top pin 110 to move upward to block the baffle 111, thereby limiting the first housing cover 105 and the second housing cover 106.

[0057] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
