Technical Field

[0001] The invention belongs to the technical field of temporary well closure at construction sites, and in particular relates to a well cover locking device and method. Background Art

[0002] During the construction process, temporary wells are usually dug on the ground. When the temporary wells are not in use, they need to be closed to avoid safety hazards. In the prior art, temporary wells are usually closed only by manhole covers. Although they can have a shielding effect, they lack the locking function of the manhole covers. The manhole covers are not installed firmly, so other people can easily open the manhole covers and enter the well without authorization, thereby causing dangerous accidents. Therefore, we propose a manhole cover locking device and method to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to solve the problem of unstable installation of manhole covers, the present invention provides a manhole cover locking device and method. The manhole cover locking device and method are further described below with specific embodiments combined with the accompanying drawings.

[0023] See also Figure 1 to Figure 3 As shown, a manhole cover locking device is used to fix the manhole cover installed on the manhole cover support, comprising:

[0024] The positioning member 1 includes a mounting portion 102 fixed around the manhole cover support 8 and a slot 103 opened on the upper portion of the mounting portion 102;

[0025] The locking member 2 includes a locking portion 202 and a pressing portion 201 for pressing on the top of the manhole cover 7, one end of the locking portion 202 is fixedly connected to the pressing portion 201, and the other end is inserted into the slot 103 with an adjustable insertion depth; and

[0026] A fixing component is used to fix the locking part to the slot. The fixing component includes two lock slot groups respectively arranged on two opposite inner walls of the slot and two electronic locks installed on the locking part and corresponding to the two lock slot groups respectively. The locking tongues of the two electronic locks extend outward and are respectively inserted into the two lock slot groups to fix the locking part to the slot.

[0027] Specifically, a plurality of locking components can be arranged around the manhole cover support 8 according to needs, so as to fix the manhole cover 7 to adapt to manhole covers 7 with different contours; the electronic lock 3 is a prior art and has the function of controlling the extension and retraction of the lock tongue 6.

[0028] Among them, see Figure 2 As shown, each of the lock slot groups includes a plurality of lock slots, and the plurality of lock slots are arranged along the length direction of the slot, and the lock tongue of the electronic lock is selectively inserted into the plurality of lock slots of the corresponding lock slot group.

[0029] By selectively inserting the lock tongue 6 of the electronic lock 3 into the plurality of lock slots 1031 , the insertion depth of the locking portion 202 into the slot 103 can be controlled, so that the pressing portion 201 is adapted to the manhole covers 7 installed at different heights.

[0030] Among them, see Figure 1-2 As shown, the positioning member 1 further includes two positioning portions 101, and the two positioning portions 101 are respectively connected to the two sides of the assembly portion 102;

[0031] The manhole cover locking assembly also includes two mounting assemblies respectively used to fix the two positioning portions 101 to the ground around the manhole cover support 8 .

[0032] Specifically, each mounting component includes a mounting piece and a mounting hole that penetrates along the thickness direction of the positioning portion 101; by passing the mounting piece through the mounting hole and inserting it into the ground around the manhole cover support 8, the assembly portion 102 can be fixed, making disassembly and assembly and reuse convenient; the mounting piece can be a pin.

[0033] Among them, see Figure 3 As shown, in this embodiment, the locking member 2 is in an inverted L shape as a whole.

[0034] Specifically, the pressing cover portion 201 is connected and fixed to the locking portion 202 to form an inverted L-shaped locking member 2, which can well achieve that one end of the locking member 2 is fixed to the assembly portion 102 and the other end is pressed on the top of the manhole cover 7, thereby fixing the manhole cover 7.

[0035] Among them, see Figure 3 As shown, the manhole cover locking assembly also includes a power supply unit 4 arranged inside the locking unit 202 and supplying power to the two electronic locks 3, and a control unit 5 arranged on the top of the pressing cover unit 201, and the control unit 5 is electrically connected to the power supply unit 4.

[0036] Specifically, the control unit 5 includes a control system connected to the power supply unit 4 by signal, and a human-machine interaction device that directly or indirectly receives control instructions. Preferably, the human-machine interaction device can be a password lock or a QR code. Taking the QR code as an example, the user can scan and identify the QR code through a smart device, such as a mobile phone, so that the smart device is connected to the control system by signal. When the control system receives the unlocking instruction, it sends a control signal to the power supply unit 4, and the power supply unit 4 supplies power to the electronic lock 3, so that the lock tongue 6 retracts, so that the lock tongue 6 is separated from the lock slot 1031, and the locking part 202 can be removed from the slot 103. The manhole cover locking assembly can be opened by remote control, which is convenient for management personnel to manage.

[0037] A method for locking a manhole cover comprises the following steps:

[0038] Providing a manhole cover locking assembly as described above;

[0039] Pass the mounting piece through the mounting hole and insert it into the ground around the manhole cover support 8, so as to fix the assembly part 102 around the manhole cover support 8;

[0040] The locking portion 202 is inserted into the slot 103 and the pressing portion 201 is pressed on the top of the manhole cover 7. The two electronic locks 3 are activated to extend the corresponding lock tongues 6 outward and insert them into the two lock slot groups 1031 respectively.
